COMPOSITE FASTENER

INTRODUCTION

The present invention concerns a fastener consisting of two components that can connect each other in a non-permanent manner. The operation is like a hook and loop fastener but has a clear technical difference.

STATE OF THE ART

The so-called hook and loop fasteners are the most well-known quick closures, which intend to connect two components.

The generic trademark Velcro often refers to these hook and loop fasteners because of the brand's prominence.

Hook and loop fasteners consist of two components: typically, two linear fabric strips (or, alternatively, round "dots" or squares) that are attached (sewn or otherwise sutured) to the facing surfaces to be attached. The first part is provided with small brackets; the second has smaller loops. When the two are pressed together, the hooks get stuck in the loops, and the two click elements are temporarily fastened or bound. When separated, the strips make a characteristic tearing sound by pulling the two surfaces apart or peeling them off.

Mr. George De Mestral invented the original technique of hook and loop fastener. He applied for a patent CH295638A in 1951 with Velcro SA as the applicant.

This hook and loop technique has some specific advantages and disadvantages.

The advantages are that it is quite efficient and is now a well-known technique. It is also washable, which allows to keep it hygienic for a longer time.

However, there is also a range of drawbacks to it. It is expensive to make, over time, it loses its effect, and it tends to accumulate hair, dust, and fur in the hooks after a few months of regular use. The loops can become elongated or broken after prolonged use. The hooks are often attached to garments, especially loosely woven items such as sweaters. These clothes can be damaged when one tries to remove the hook and loop fastener, even if the sides are slowly separated. It also absorbs moisture and perspiration when worn on the skin, which means it will smell if not washed.

In addition to Velcro's original hook and loop fastener, there are also some variations on the market. The Slidingly Engaging Fastener is designed to address various issues with common hook and loop fasteners. Heavy-duty variants have mushroom-shaped stems on each plane of the clasp, which give an audible click when the two planes fit together. In addition, a strong pressure-sensitive adhesive adheres each part to its substrate.

SUMMARY

The present invention and versions thereof offer a solution to one or more of the disadvantages mentioned earlier. To this end, the present invention relates to composite fasteners and processes as described in the claims and further below.

The present invention relates in a first aspect to a building block, typically used in a set of multiple of said building blocks, comprising a substantially hollow body with a closed upper face, one or more closed walls projecting downward from said upper face, and an open lower face, wherein the closed upper face comprises a plurality of pins on the top side in a regular grid pattern, and wherein the bottom side of the upper face comprises a plurality of pins in a regular grid pattern. The walls comprise wall pins on the inwards facing side, said wall pins extending from the bottom side of the upper face along the walls, wherein said wall pins are part of the regular grid pattern defined by the plurality of pins on the bottom side of the upper face, preferably wherein the wall pins are shaped as a section of a pin on the bottom side, said section defined by a plane bisecting the pins parallel to the longitudinal axis of the pins, and more preferably said plane comprising the longitudinal axis of the pins.

The pins and the wall pins comprise at least one anchoring segment along the longitudinal axis with a radius greater than a radius of an underlying segment of the pins and wall pins respectively, and optionally a greater radius than a radius of an overlying segment of the pins.

The pins are flexible, for instance made up of a flexible material or by reducing the thickness of a rigid material to provide some flexibility, and the anchoring segments of the wall pins are flexible, for instance made up of a flexible material (or by reducing the thickness of a rigid material to provide some flexibility.

The pins on the top side, and the pins and the wall pins on the bottom side are configured such that when the top side of the building block is pushed against the open lower face of an other of said building blocks, the pins of the top side of the building block and the pins of the bottom side and the wall pins of the other of said building blocks flex to allow at least one of the anchoring segments of the pins of the top side of the building block to move past the anchoring segments of at least three of the pins of the bottom side and of the wall pins of the other of said building blocks, to place the building block and the other of said building blocks in an attached state. In a further embodiment, at rest, the pins on the top side are distanced from each other such that the anchoring segments of the pins of the top side at rest have a distance between them which defines a free space between the anchoring segments in the plane parallel to the upper face where a transverse cross-section of the anchoring segments of the pins and wall pins on the bottom side does not fit in, and wherein the underlying segments of the pins of the top side at rest define a space between the underlying segments in the plane parallel to the upper face where a transverse cross-section of the anchoring segments of the pins and the wall pins on the bottom side does fit in, in a way that when the top face of said block and the bottom face of an other of said blocks are pushed together facing each other with the anchoring segments of the pins on the top side of said block past the anchoring segments of the pins on the bottom side and the wall pins of the other of said blocks, the pins and wall pins hold each other clampingly Further embodiments are described in the claims. However, it should be noted that any of the teachings regarding the other aspects of the invention can be incorporated in the first aspect. As such, it is clear that the pins, anchoring segments and other parts (corner and wall pins being sections of the pins) may comprise any further features or characteristics as defined for these elements in terms of other aspects of the invention and vice versa. As such, the teachings of the further embodiments are to be considered as further embodiments for the present aspect, and the contents to be transferable thereto. For instance, the pins on the top side of the upper face are preferably rotated over about 45° with respect to the pins (and wall and corner pins if present) on the bottom side of the upper face.

In a preferred embodiment, the anchoring segments have a maximal diameter of at most 5.0 mm, but more preferably 4.0 mm or even 3.0 mm. Most preferably, the maximal diameter is about 2.75 mm, for instance 2.7 mm or 2.6 mm or 2.5 mm or 2.4 mm or less, such as 2.2 mm, 2.0 mm.

In a preferred embodiment, the anchoring segments have a minimal diameter of at least 2.0 mm, but more preferably 2.25 mm or even 2.5 mm.

In a preferred embodiment, the pins have a minimal diameter of at least 1.5 mm, preferably at least 1.75 mm, more preferably at least 2.0 mm or even 2.1 or 2.2 mm.

In a preferred embodiment, the pins have a maximal diameter, excluding the anchoring segments, of at most 2.5 mm, preferably at most 2.4 mm, or even 2.3 mm, 2.2 mm or less, for instance 2.1 mm, 2.0 mm.

Most preferably, the minimal difference in diameter between the anchoring segments and the rest of the pin is at least 0.1 mm, preferably at least 0.2 mm, more preferably at least 0.3 mm or even 0.4mm. Preferably, said minimal difference is capped at at most 0.75 mm, more preferably at most 0.6 mm, even more preferably at most 0.5 mm or even 0.4 mm.

An example of this would be pins with a diameter of 2.6 mm at the anchoring segments, and 2.2 mm at the other segments.

In a second aspect, the invention relates to a tile assembly comprising at least one connection strip, preferably a plurality of connection strips, and at least one tile, preferably a plurality of tiles. The connection strip is a substantially flat body comprising a coupling side and a preferably flat back side for attachment to an underground, wherein the coupling side comprises a plurality of pins in a regular grid pattern, preferably arranged in equidistant rows and columns.

The tile comprises a coupling side and a preferably flat back side, wherein the coupling side comprises a plurality of pins in a regular grid pattern, preferably arranged in equidistant rows and columns.

The pins comprise at least one anchoring segment along the longitudinal axis with a radius greater than a radius of an underlying segment of the pins, and optionally a greater radius than a radius of an overlying segment of the pins.

The pins of the tile, and preferably furthermore the tile, and/or the pins of the connection strip and preferably furthermore the connection strip, being flexible. It should be understood that for instance, the tile itself can be made from a rigid material, with the pins on the tile themselves being essentially rigid, wherein the flexibility of the pins of the connection strip allows the pins of the tile to be pushed into between the pins of the connection strip. Vice versa, the tile pins may be made flexibly, with the connection strip pins being rigid, under the same principle. Finally, in some occasions each set of pins is flexible, and potentially also the carrier (tile or strip) thereof. This flexibility can be ensured by making the pins of a flexible material and adding these to the building block, or can be made from the same material, where the pins are made flexible by choosing an appropriate thickness (or rather thinness), which provides for some flexibility.

The pins on the tile, and the pins on the connection strip are configured such that when the coupling side of the tile is pushed against the coupling side of the connection strip, the pins of the tile and the pins of the connection strip flex to allow at least one of the anchoring segments of the pins of tile to move past the anchoring segments of at least three of the pins of the connection strip, to place the tile and the connection strip in an attached state.

In a further embodiment, at rest, the pins of the tile are distanced from each other such that the anchoring segments of the pins of the tile at rest have a distance between them which defines a free space between the anchoring segments in the plane parallel to the coupling side of the tile where a transverse cross-section of the anchoring segments of the pins of the connection strip does not fit in, and wherein the underlying segments of the pins of the tile at rest define a space between the underlying segments in the plane parallel to the coupling side of the tile where a transverse cross-section of the anchoring segments of the pins of the connection strip does fit in, in a way that when the tile and the connection strip are brought together with the coupling surfaces facing each other, the pins hold each other clampingly.

Further embodiments are described in the claims. However, it should be noted that any of the teachings regarding the other aspects of the invention can be incorporated in the second aspect. As such, it is clear that the pins, anchoring segments and other parts may comprise any further features or characteristics as defined for these elements in terms of other aspects of the invention and vice versa. As such, the teachings of the further embodiments are to be considered as further embodiments for the present aspect, and the contents to be transferable thereto. For instance, the pins on the connection strip are preferably rotated over about 45° with respect to the pins on the tiles, while the grids of the tiles and connection strips are essentially the same (but shifted relative to each other when connected).

The present invention relates in the further aspect to composite fasteners consisting of at least a first click element or carrier and a second click element or carrier, at least wherein the first click element comprises pins provided on at least one side, the coupling surface, and an opposite second click element that contains at least pins provided on at least one side, the coupling surface, and wherein the two click elements can click together. The click elements or carriers comprise a coupling surface wherein many pins are provided, preferably in a regular grid pattern, preferably with equidistant rows and columns so that they are provided in a regular matrix pattern, typically rectangular or square. The pins comprise at least one anchoring segment along the longitudinal axis, which has a greater radius than an underlying segment (recess), and, optionally, a larger radius than an overlying segment (recess or pin top). The pins are preferably flexible, for instance made of a flexible material or by reducing the thickness of a rigid material to provide some flexibility.

Here the pins of the first carrier are distanced from each other at rest so that the anchoring segments of the pins of the first carrier have a distance between them which defines a free space between the anchoring segments in the plane parallel to the first carrier where a transverse cross-section of the anchoring segments of the pins of the second carrier does not fit in. In addition, they are distanced from each other in such a way that the underlying segments of the pins of the first carrier at rest define a space between the underlying segments in the plane parallel to the first carrier where a transverse cross-section of the anchoring segments of the pins of the second carrier fits in, such that when the first and second carrier are brought together with the coupling surfaces facing each other, the pins hold each other clampingly.

According to a certain preferred design, the click elements comprise at least one coupling surface with many pins on top, preferably in a regular grid pattern, preferably with equidistant rows and columns so that they are provided in a regular matrix pattern, typically rectangular or square.

The pins comprise at least one anchoring segment along the longitudinal axis, which has a greater radius than an underlying segment (recess), and, optionally, a larger radius than an overlying segment (recess or pin top). The pins are preferably flexible, for instance made of a flexible material or by reducing the thickness of a rigid material to provide some flexibility.

The pins are distanced from each other on the carriers (click elements) such that the anchoring segments of the pins of the first carrier have a distance between them equal to or greater than the pins at the recesses (underlying and optional overlying segments) but smaller than the radius of the anchoring segments of the pins of the second carrier, such that when the two carriers are brought together with the coupling surfaces facing each other, the pins hold each other clampingly.

The shape of the pins must be considered. For example, with square transverse cross-sections, a different interaxial distance must be considered compared to disc-shaped transverse crosssections of the pins.

"Transverse cross-sections" refers to cross-sections of the pins in a plane perpendicular to the lengthwise axis or longitudinal axis of the pins. Depending on the specific shape of the crosssection, the dimensions of the anchoring segments and the recesses below can be adjusted to ensure successful anchoring. In addition, the dimensions can also be further adjusted (more significant difference between the radius of anchoring segments and recesses) to obtain a more substantial or smaller difference to obtain a weaker connection.

According to a preferred embodiment, the click elements are periodically provided with a series of pins that are provided with a set of protrusions or anchoring segments (also called ribs) and recesses below on the side, with the protrusions of the pins of the first click element adjusted to match the recesses under the anchoring segments of the pins of the second click element and vice versa, and preferably so that they fit into the recesses of the pins of the second click element and the protrusions of the second click element into the recesses of the first click element. In what follows, these recesses are also referred to as a overlying, underlying, or intermediate segments relative to the ribs (or protrusions or anchoring segments). According to a preferred embodiment, the first and/or second carriers are flexible. Preferably, the carriers and pins on them are single-piece, allowing, for example, manufacture via 3D printing, injection molding, or other automated processes.

According to a preferred embodiment, the pins have multiple anchoring segments, with segments (recesses) with a lower radius in between. Preferably, all anchoring segments have substantially the same shape and dimensions and the recesses in relation to each other.

The general principle of the present invention is a method in which the pins of two different click elements exert a clamping effect on each other to obtain a clamping effect between the replaced click elements.

According to one aspect of the invention, the quick closure is formed by clicking two identical click elements together. This contains a base consisting of a plastic panel with pins on one side, wherein the sides of these pins are provided with recesses. These recesses have the shape of a barb. The hooks of these barbs are directed towards the surface of the base, with the function of the barb being active in the direction away from the surface and perpendicular to the surface of the base panel. Preferably, barbs are provided at the corners of the anchoring segments, as also visible in Fig. 1. In addition, by suitable positioning of the barbs, it can be ensured that the barbs of the pins of a first click element for two anchored click elements at rest, coincide with the barbs of the pins of the second click element, and thereby hooking together. The number of recesses is at least one per side, but preferably two, three, or even more. The pins can be square in shape, with the top beveled and/or rounded. These pins are at a certain distance from each other via an ordered pattern. This distance is equal in the x and y directions. The axis distance of the different pins is preferably equal to the distance of the maximum side or diameter of the pins increased by 50%, making it possible to link two click elements with each other. The height of the pins is preferably equal to the axis distance of the pins but can be longer or shorter depending on the desire for a stiffer or more flexible coupling. The sides of the adjacent pins are positioned in parallel with respect to each other. The intention is to apply the click elements that are identical to each other as a quick release. Two identical click elements are placed on top of each other with the top sides of the pins facing each other, with one click element rotated 45° in relation to the other click element in such a way that the pins of the one click element are rotated 45° around their longitudinal axis in relation to the pins of the second click element when brought together for linking. The two click elements are then pressed together. Since the one click element is rotated 45° in relation to the other click element, the patterns of the two click elements do not match. As a result, some pins of the one click element push the pins of the other click element away to a certain angle, those other pins hook into each other or almost do not push each other away, and some pins do not actively hook into other pins. With the (barb) hooks or ribs on the side of the pins, the protrusions are smaller than the recesses of the corresponding pins of the other click element in which they hook. In this version, the two click elements can be connected to each other in any place. A connection can also be made that has a curved shape in the basic direction.

Another aspect of the invention is that the quick closure is formed by clicking two different click elements together. The first click element contains a base consisting of a plastic panel with pins on one side, wherein the sides of these pins are provided with recesses and ribs anchoring segments. These recesses are in conjunction with the anchoring segments equipped with one or more barbs. The hooks of these barbs are directed towards the surface of the base, wherein the function of the barb is active when the retained element moves in the direction away from the surface (and perpendicular to the surface) of the base panel.

The number of recesses is at least one per side, but preferably two, three or even more. The pins can be square in shape, with the top beveled and/or rounded. These pins are at a certain distance from each other via an ordered pattern. This distance is preferably essentially equal in the x and y directions. The interaxial distance between directly adjacent pins (closest pins) is preferably at least 2.0 times the minimum radius of the anchoring segments, more preferably at least 2.10 times the minimum radius, and most preferably at least 2.25 times to even at least 2.5 times. This ensures a certain resistance between the anchoring segments when the pins of click elements are brought past each other.

Preferably this interaxial distance is a maximum of 4.0 times the minimum radius, but more preferably this is lower, namely a maximum of 3.5 times, or (2+V2) times the minimum radius. With the most obvious preference, it is a maximum of 3 or 2.5 times the minimum radius. By limiting this, it is ensured that once the pins of the click elements are linked (with the anchoring segments that are moved past each other), they cannot simply be disconnected due to the lateral forces that the pins exert on each other.

The interaxial or axis distance of the different pins is preferably equal to the distance of the maximum size of the pins plus 50%. The height of the pins is preferably equal to the axis distance of the pins but may vary depending on further requirements.

In a preferred embodiment, the pins are provided with two or more ribs or anchoring segments on top of each other, making it possible to anchor the click elements to each other on multiple levels, thus obtaining a more robust and more reliable attachment. In a preferred embodiment, the anchoring segments have a larger minimum radius than the maximum radius of the underlying segments. This guarantees a firm anchoring under any relative orientation.

The adjacent sides of the pins are arranged in parallel to each other. The second click element is similar in execution to the first click element, wherein the pins are provided in the same pattern but are rotated at an angle of 45° around their own axis, so the adjacent pins are facing each other with the angular sides (with the pins of the first click elements with the sides facing each other).

The intention is to apply the two different parts as a quick closure. Two different click elements are placed on top of each other, with the header sides of the pins facing each other, wherein the pins of the one click element fit between the pins of the other click element. Then, the two click elements are pressed together. Since the pins of the second click element are rotated 45° in relation to the first click element, but the patterns of the two click elements do match, the pins will be fixed in the free spaces. Each pin will be clamped by a pin of the other click element in the middle of each side of it. With this arrangement, almost all pins remain upright. In this version, only connections can be realized with an interval equal to the interaxial distance or axis distance between the different pins. Also, no connection can be made that has a pronounced curved shape.

However, under certain adaptations, curved connections are enabled, for instance by increasing the distance between the pins according to a first axis in the plane of the grid pattern, allowing the carriers to be connected under a curved shape, with the curve being along said first axis (i.e., curved around a second axis in the plane of the grid pattern, perpendicular to the first axis).

Alternatively (or building further on the above), the carriers can be connected after being heated slightly, to increase their deformability/elasticity. Once the connection is established, the carriers will return to a lower temperature (naturally or artificially) and set themselves in a strong connection.

The adhesion between the different click elements is optimal if the recesses have the shape and function of barbs. However, in the setups described in the previous versions, it is very complex and expensive to form the pins by forming them directly with injection molds or other techniques that use molds to form the recesses in the sides of the pins.

According to an alternative technique, the recesses are formed after the pins themselves are formed and after they have been removed from the molds. The recesses in the side of the pins or even the shape of the pins themselves can be formed in a second phase by using machining tools that pass along the sides of the pins and machining parts of the pins, by using, for example, small chisel-shaped tools where a piece of the pins can be removed in several steps so that they form the desired recesses such as forming the barb. This is possible for the different shapes as described in the previous versions.

According to another aspect of the invention, the pins may have a different shape than squares in terms of a transverse cross-section. These can be round, triangular or polygonal (preferably regular polygons, especially hexagonal or octagonal) in general. In height, the base shape of the pins can be straight, conical, inverted conical, or any other arbitrary shape. However, the preferred shape is to make it slightly conical with a minimum angle of 0-10°, preferably 0.5°-5° or even l°-2°, to make it easier to remove the shape from the production mold after injection molding.

Preferably, the width-height ratio of the pins is a ratio that is between one to two and one to three of the diameter or side in the base in relation to the height of the pin.

The top of the pin is preferably rounded or at least beveled so that the pins of the opposing click elements can push each other away if they touch each other on the ends and can, therefore, more easily interlock. Preferably the same applies to the top of lower ribs or anchoring segments for the same reason.

According to another aspect of the invention, the two click elements may be identical in a pattern when hooking together. Here, the center points of the pins are equally far from each other according to the same pattern. When hooking in the two click elements, the pins are not or hardly pushed away from each other, but the protrusions of the pin of the one click element hook into the recesses of the other click element and vice versa. In the version where the pins have a square shape, the pins of the opposite click element should be rotated 45° around their axis, but the same pattern is used. This has the effect that when clicking the two click elements together, the angular sides of the pin of one click element press into the lateral sides of the other pins. This gives a point load that makes it possible for the pins to be pressed together with a compressive force and pulled back apart with a tensile force, which is workable for its applications as is now applied in the current so-called hook and loop fastener applications. In particular, this is possible due to the flexible nature of the click elements and the pins, which makes it possible to detach external pins with the necessary (conscious) manipulation, and thus gives the pins located more to the inside the necessary freedom of movement to be detached. With this version, it is not or hardly possible that the click elements can take on a curved shape. Again, it is noted that some adaptations/alterations can be applied to enable curved shape connections for the fastener, such as extending inter-pin distance along a first axis and/or heating the carriers before connection, as mentioned previously. According to another aspect of the invention, the two click elements may be identical in a pattern when hooked together. The center points of the pins are the same distance from each other according to the same pattern and arrangement. When hooking in the two click elements, the two click elements are preferably rotated 45° in relation to each other before pressing them together. Some pins are not or hardly pushed away from each other, and other pins push the opposing pins away from each other to a large or lesser extent. In this version the click elements can take on a curved shape. An additional feature is that the click elements can be connected in a stepless way.

Preferably, the dimensions of the pins of the click elements are substantially the same (similar width and length), although this may differ. For example, you can opt for thicker pins on one click element and thinner pins on the other, or even a mix according to a predetermined pattern, although the latter is less preferable as the two click elements must be placed more accurately in relation to each other for a good link.

According to another aspect of the invention, the materials of the click elements can be composed of a uniform material such as a plastic such as LDPE, PLA, PVC, EVA, Z-PVC, PU, TPE, TPV, without having an exhaustive effect. Moreover, these can be hard, flexible, or semi-flexible. But other materials, such as carbon, steel, copper, etc, are also possible. These may or may not be flexible.

Also, the click elements that can be clicked together can be different in material.

According to another aspect of the invention, the materials of the click elements may be constructed from a composite material such as a plastic base combined with a steel band, a plastic base combined with steel pins, a steel base with plastic pins, or other possible variants.

According to another aspect of the invention, the basis of the present invention can be further supplemented with a hook connection. This hook connection has the function of blocking at least one side of the connection. The hook connection can be composed of a pin with a sphere or other widening on the one click element and an opening in the base panel. The opening in the other click element is provided so that the sphere of the pin can pass through smoothly and is also provided with an offshoot of the opening that is narrower than the opening through which the sphere can pass. After the sphere has been applied through the opening, the one click element is shifted relative to the other click element so that the sphere is positioned behind the narrower opening so that the two click elements are locked with each other. Since this connection is relatively weak, the two click elements are applied together according to the techniques described in the present invention. In a setup where the pins of one of the click elements are pushed through a fabric, all pins of this click element are pushed through the meshes of the fabric, whether or not including the pins provided with the spheres. The openings provided in the other click element are applied over the spheres and blocked by means of a pulling or pushing movement. Then the two click elements are pressed together. When tightening the fabrics in an opposite movement, an outward pressure will be applied to the pins of the click elements. The hook connection will absorb this pressure so that the pins of the different click elements remain hooked together and can therefore absorb high lateral forces. The crochet technique described above can be replaced by alternatives that have the same result within the intended objective.

According to another aspect of the invention, the dimensions of the two click elements are different in size. For example, the thickness of the different base panels can differ r, so that you get, for example, a click element that is quite stiff in which a more flexible click element can be clamped. But the click element's length and/or width can also vary. So, for example, several smaller click elements can be placed on a larger click element.

In an alternative aspect, the dimensions, or at least the thickness, are substantially the same for both click elements.

The dimensions of the pins themselves can also be different from each other. These can be compared to the different click elements, but also within the same click element, different sizes, shapes, numbers, and versions of the pins can be possible. The recesses on the pins can also be different with the different click elements but also within the same click element.

In a certain version of the present invention, the attachment between the different click elements uses a mix of attachment intensity in which the pins of the different click elements interact with each other in different places differently. By distributing the pins unordered over the base panel, a configuration can be created in which the click elements are clicked together at any place and/or at a random angle, whereby enough pins then apply pressure to each other to obtain a sufficiently strong connection.

In a certain version of the present invention, the attachment between the different click elements uses a mix of attachment intensity in which the pins of the different click elements interact with each other in different places in a different way. By dividing the pins over the base panel in an orderly but not symmetrical and/or linear way, a configuration can be created in which the click elements are clicked together at any place and/or at any angle, whereby enough pins then apply pressure to each other to obtain a sufficiently strong connection.

According to another aspect of the invention, the click elements can be provided with pins on both sides of the base panels. Another possible version is that the base panel is provided with pins on one side and on the other side a device to connect with another material where a different technique is needed, such as barbs, glue connection, screw connection, clamp connection, and other possible known connection techniques.

According to another aspect of the invention, the base of the click element may be part of a tool or other instrument. For example, the click element can be integrated into a clamping plier or other clamping mechanisms where the jaws of the tool or instrument is equipped with the pins as described in the present invention. But other parts such as a profile or a tube can also be provided with the described pins.

According to another aspect of the invention, the pins have the following possible shapes in terms of transverse cross-section, rectangle, square, round, polygon, or other possible geometric shapes. The shape may possibly be arbitrary in shape.

All sides of the pin are preferably provided with recesses to make the engagement in the opposite pin as efficient as possible.

The combination of recesses and protrusions can come in the execution of: barbs, squares, triangles wherein the flat side is preferably arranged so that it hooks on the flat side of the opposite pin, rib shapes wherein the side is composed of layered protrusions, this with a similar effect as in 3D printing, recesses in any shape, protrusions in random shape and other possible shapes that allow the hooking of the two opposing pins. Another possible version is that the pins have a rough surface so that the pins experience more resistance when they slide over each other, and thus a more significant clamping effect is obtained.

According to another aspect of the invention, the pins of the opposing click elements can be permanently connected to each other by using an adhesive bond. This can be by adding external glue or heating the click elements so that the pins merge. A variant of this is to obtain a semipermanent adhesive bond by using external glue with a limited adhesive strength or to determine the pins' material so that these spiked ones can melt into each other.

The operation:

The principle of the invention is to clamp the pins by applying two click elements that are provided with pins by moving them in the opposite direction toward each other. Here the pins push laterally against each other, creating a clamping effect.

There are two main configuration techniques:

1) here, a random curved arrangement is possible

Pins are pushed away in all directions

Preferably, the click elements used are identical but can also be variable

2) a random curved arrangement is not possible The click elements are preferably identical, depending on the version (sometimes the pins of the one click element must be longer than the pins of the other click element).

Only the curved shape is possible if the pins are further apart in an ordered and proportional way than the pins of the other click element, and this is only in the x-direction and not in the Y direction, for example.

Possible applications of the present invention without wanting to work exhaustively are: Connecting bandages or bandages where, according to a preferred embodiment form, the pins of one click element are longer than the other. The click element with the longer pins is pressed through the bandage. For this specific version, it is preferable to use a bandage with perforations wherein the central point of the perforations is equal to the central points of the pins applied by the bandage. The second click element is connected to the bandage on the pinless side, preferably at the end of the bandage. This connection can be made by a melting connection in which the bandage is fused in the click element, but it can also be done via a glue connection, a connection with barbs, or another connection.

Another possible application is a connection for a walking accessory such as a shoe. The hook and loop fastener technique is already frequently used in shoes to replace and/or supplement the well-known laces. The disadvantage of the hook and loop fastener technique is that over time it becomes less efficient in the adhesive force and that dirt can drastically reduce the operation of the hook and loop fastener. The aforementioned disadvantages can be eliminated by applying the present invention's fastening technique. For this application, it is preferable to use the version in which the attachment can take on a curved shape.

Other possible applications without wanting to enumerate exhaustively are belt connections, tent connections and fences, classic wall connection for hanging of mirrors and related applications, fixing of or to window screens (the mesh stucture is ideal for coupling with the carriers), holding seat upholstery in place, fixing mats, and the like.

Advantages

The present invention is mainly a competitor for the hook-eye connection and, more specifically for the version known under the brand name Hook and loop fastener.

It has the following advantages

• Minimal noise: With the traditional hook-eye connection, loosening the joint causes a significant noise due to pulling the hooks from the loops. This is not the case with the present invention.

• Washable and hygiene: with the traditional hook-eye connection, dirt sticks to the hooks, and dirt creep into the eyes. In the execution of the present invention, no dirt sticks, and is also very easy to clean, both manually and mechanically. The click elements can also be disinfected easily, making it suitable for use in the food and medical sectors. But also for swimming pools, playgrounds, hospitals, etc.

• Environmentally friendly: the click elements can be constructed from one material, and this material can be an environmentally friendly material such as bioplastic. This makes it not only environmentally friendly but also relatively cheap to produce.

• Adaptable: with most versions in plastic, it is also possible to cut and/or cut the click elements to size. • High forces: the specific structure of the click elements means that the lateral forces that can be absorbed are much higher than the traditional hook-eye connection. This makes the present invention suitable for heavier transport and vehicles and for more extreme applications.

• Glueable: since the click elements in most cases do not contain a woven fabric, and the click elements can also be glued together.

• Cheaper production: The simple construction of the click elements means that the production cost is much lower than with the traditional hook-eye connection, especially in the versions wherein the opposite click elements are identical or almost identical.

• Reliability: with the traditional hook-eye connection, hooks regularly break off after multiple uses. This does not play a role in the present invention

• Additional advantages are that most versions, according to the current invention, do not immediately stick. So it does not hurt if you hold the pins or walk over them and does not stick to the clothes if you wash them together, for example.

All references cited in this specification are hereby incorporated in their entirety by reference. In particular, the doctrine of all references specifically referred to here is to be incorporated by reference.

Unless otherwise defined, all terms used in revealing the invention, including technical and scientific terms, have the meaning as generally understood by one of the ordinary skills in the field to which this invention belongs. Through further guidance, definitions for the terms used in the description are included in the present invention's teachings. The terms or definitions used herein are given solely to assist in understanding the invention. Reference in this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or feature described in connection with the embodiment is included in at least one embodiment of the present invention.

So, the appearances of the expressions "in one composition" or "in a composition" in different places in this specification do not necessarily all refer to the same version but can. In addition, the special features, structures, or characteristics can be combined in any appropriate way, as would be clear to a professional from this description, in one or more embodiments. In addition, although some embodiments described herein include some but not other features included in other versions, combinations of features of different versions are intended to fall within the scope of the invention and constitute different performances, as will be understood by the craftsman.

For example, in the following claims, any of the claimed embodiments can be used in any combination.

The terms "first click element" and "second click element" refers to two types of click elements, which can still be of the same type.

When using the x, y, and z-axis as an indication, the example, wherein the click element is arranged horizontally, refers to the x-direction as the horizontal longitudinal direction, i.e., the direction on which the forces are applied. The y-direction stands for the width in the horizontal direction of the click element, and the z-axis is the vertical direction in which the click elements are moved to or from each other.

When defining the parts, such as the pins, gradients can be used to determine the shape of the pins according to the z-direction. This is preferably between 0 and 1°, but can also work with gradients between 1 and 3°, with possibilities up to 5°, and depending on the implementation of combination recesses and protrusions of the pins can, the shape of the pins themselves or a combination of shapes and/or different materials of pins, the slope of the pins can be >5° and the gradients can even be negative.

When defining the composition of the click elements wherein the arrangement of the pins of one element in relation to the other element is determined, it is preferably 45° but can also be larger than 45°. Depending on the design and/or composition of the elements, the shape of the pins themselves, or a combination of shapes and/or different materials of pins, the rotation difference between them can be between 0 and 180°.

The basis of the invention is the principle whereby the pins 17 of opposite click elements are provided with recesses wherein the pins 17 exert a certain pressure on each other if the click elements are pressed on each other and the opposite pins 17 touches each other. Fig. 1 shows some possible versions of pin 17 that allow efficient clamping. The preferred shape is a square as a basic shape that runs very slightly conical upwards, in the z-direction, to enable production via spray molding. Preferably, the angle of the conical shape is less than 1°. Fig. 1 shows four possible embodiments. The most leftside pin 1 has double ribs 5 that have the shape of a barb at the corners of it. These types of pins 17 are the most efficient but are quite more difficult to manufacture. The second pin 2 is provided with a single rib 5 with a flat bottom, the third pin 3 with double ribs 5 with a flat bottom 3, and the fourth pin 4 with a triple rib 5 with a flat bottom. The versions where the ribs 5 are provided with a flat bottom are easier to produce than the ribs 5 that has the shape of a barb. When applying the opposite click elements, the ribs 5 hook together with their flat side. Note that the barbs can also be provided in the second and fourth pin versions. Fig 2 shows single pins 4 with triple ribs 5 with a flat bottom arranged in the opposite direction.

In Fig 3, two opposing click elements interlock with the pins 4 of the different click elements positioned at the same center distance from each other, but pins 4 of one engagement click element 7 are rotated 45° in relation to the other engagement element 6. The pins 4 of both click elements are equipped with three ribs 5. When engaging, the protrusions, which form the ribs 5 of the pins 4, are positioned in the recesses 15 of the opposite pins 4. Fig 4 shows a principle representation of the two click elements in which the pins of one click element 7 is rotated 45 ° in relation to the other click element 6 and positioned towards each other. Fig 5 shows the basic components when the two click elements are clicked together, as shown in Fig

3. In this version, the pins are square in shape so that the angular sides of the pins 4 push into the middle of the long sides of the opposite pins 4.

In Fig 6 and Fig 7, replaced opposite but identical click elements 6 interlocks with the two click elements are rotated 45° in relation to each other. The pins 4 of both click elements are equipped with three ribs 5. When taking hold, the protrusions, which form the ribs 5 of the pins

4, are positioned as much as possible in the recesses of the opposite pins 4 but more randomly. Fig 8 shows a principle representation of the two click elements, in which one click element 6 is rotated 45 ° in relation to the other click element 6 and positioned towards each other. Fig 9 shows the basic composition if the two click elements 6 are clicked together, as shown in Figs 6 and 7. In this version, pins 4 are square in shape, but the sides and corners interlock in a random way. The chamfered sides of the top of the pins cause the pins to lie next to each other and interact, but this is done fairly randomly, depending on the desired distance and the bending of the base panels.

In some situations, it may be necessary to provide an additional blockage. For example, if the fastener is used to attach a bandage. As shown in Fig 12, on the base panel 21 of element 8, which is equipped with blocking pins 14, there is a substance 12 with openings. Because of this fabric 12, both the pins 17 and the blocking pins 14 are pushed so that the fabric 12 touches the base panel 21. The other click element 9 that is equipped with the blocking recess 16 is the fabric 18 on the outside of the click element 9. The connection between the click element 9 and the fabric 18 of, for example, the bandage can be done by means of glue, but also, for example, by providing barbs or a combination of these. As shown in Fig 10, the two click elements 8 and 9 are clicked together with the blocking pins 14 fitting through the blocking recess 16. When the two click elements 8,9 click together, the blocking pins 14 are first placed in the blocking recesses 16 at a certain angle. The blocking recesses have a shape that is defined so that the sphere 24 of the blocking pins 14 fits through them, with a spur that narrows so that the sphere 24 remains behind the base panel 21 of the click element 9. As soon as the sphere 24 has reached the final position of the constriction, the two click elements 8, 9 can be clicked together in a similar way as described above. A variant of this is shown in Fig 11. A two click elements 10, 11 that fit together are equipped on both sides with a blocking device consisting of the combination blocking pins 14 and blocking recesses 16 wherein the operation is similar to that described in Fig 10. However, when applying the blocking pins 14 in the blocking recesses 16, the base panel 21 of one click element 10 must be able to be bent to move the blocking pins 14 through the openings of the blocker recesses 16. When the pins 17 are clicked together, the blocking pins 14 will automatically move to their endpoint in the blocking recesses 16.

Many applications and variants are possible regarding the clicking together of the two click elements as a fastener. Figs 13 and 14 describe a variant in which the base panels 21 of the different click elements 13 are connected by a flexible bracket 22. When folding the two opposing click elements 13, the opposite pins 1 interlock with the pins 1 of the different click elements 13 positioned at the same center distance from each other, but the pins of one part of the engagement click element 1345° are rotated in relation to the other part of the engagement element 13. The pins 1 of the two parts of the click element 13 are equipped with two ribs 5 of the barb principle 1. When engaging, the protrusions, which form the ribs 5 of the pins 1, are positioned in the recesses of the opposing pins 1. One part of the click element is equipped with an extension 23 in which an eye 19 is provided so that a suspension device is formed. This is preferably composed of the same material as the base panels 21 of the click element 13.

An additional preferred embodiment, as shown in FIG 14, consists of a click element 6 that is extended with a foil 25. This allows the click element 6 to be attached to a smooth surface such as a tile. The air is pushed from under the foil 25, creating a suction effect and the click element sticking to the wall. Another object equipped with an opposite click panel 7 can be attached to the first click element 6. The advantage of such a version is that the whole side of the click element 6 and foil 25 can be built from 1 material, which greatly simplifies the production. According to another aspect of the invention, pins 17 and protrusions or ribs 5 have the following possible shapes in terms of transverse section, rectangle, square, round, polygon, or other possible geometric shapes. The shape of the pin itself may differ from the protrusions or ribs 5. In some preferred embodiments, it is appropriate and even necessary that the corners of the square or rectangular shapes be rounded in general.

An additional preferred embodiment, as shown in FIG 16, 17, and 18, is a click block 26 with the same function as the well-known LEGO block.

The click block 26 has external pins 3 at the top and internal pins 38 at the bottom. In this embodiment, the internal pins 38 are 45° rotated relative to the external pins. The external pins 3 and internal pins 38 are arranged in the x- and y- direction at an equal distance, making the click blocks 26 to be connected compatible both in the longitudinal direction and the transverse direction.

Another embodiment is possible wherein the external pins 3 and their ribs 5 have a round shape, and the internal pins 38 and related ribs 5 have a square shape or vice versa.

Combinations are also possible where, for example, the pins 17 themselves are square in shape, and the shape of ribs 5 is round.

The shapes of the pins 17 and ribs 5 can be used randomly together depending on the desired effect.

Fig 18 shows a transverse section of an arrangement of two superimposed click blocks 26. If these two click blocks 26 are pressed together, the external pins 3 at the top fill the space between the internal pins 38 from the bottom. The walls 27 of the click block 26 are equipped with wall pins 28 which provide an additional clamping of the external pins 3.

To ensure that the click blocks 26 cannot move sideways concerning each other when mounted, it is recommended that the dimensions of the external pins 3 and internal pins 38 are defined in such a way that the angular side of at least one pin touches the protrusion of the opposite pin. If the protrusions have a square shape, the angular side touches the center of the side of the square of the opposite rib 5.

In Fig 16-17-18, click blocks are provided with a set of external pins 3 and a set of internal pins 28.

The outside of the walls can possibly be provided in x-, y- and z- directions with an extra set of external pins 3 and/or internal set of pins 28, with or without additional walls 27.

The pins can be identical in shape and arrangement on both sides but also opposite in shape and/or arrangement. The protrusions of ribs 5 on the pins can be partially or entirely provided around the pin. Depending on the desired adhesive strength, these can be adjusted in shape and dimensions.

For the operation in general and considering the click blocks 26, it is recommended that the protrusions have a difference in size compared to the pin of 0.2mm, possibly 0.1 or 0.3 mm but preferably no larger than 0.4mm. This is independent of the size of the pins themselves. As an example, if the pin and protrusion are both square in shape and the pin itself has a width of 2mm between the parallel sides, the protrusion preferably has a width of 2.4mm between the parallel sides, possibly 2.2mm or 2.6mm but preferably no more than 2.8mm.

The ratios of the height of the ribs 5, the width of the ribs 5 between the parallel sides, and the number of ribs 5 also determine the strength of the connection between the internal pins 38 and external pins 17. This allows click blocks 26 with different adhesive strengths to be combined with each other.

It is recommended that the edges of the walls 27 of the click block 26 are rounded on the outside, which gives the advantage that they feel much softer in contrast to the current Lego blocks made in hard plastic.

One possibility is that the walls 27 of the click block 26 are pressable in a transverse direction. This creates a spring effect in which the ribs 5 of the external pins 3 can hook behind the internal pins 38 by pressing the wall 27 lightly. When releasing the tension on wall 27, wall 27 wants to return to its original position, whereby jacking the external pins 3 with the internal pins 38 under tension creates a solid connection.

Fig 17 shows a possible embodiment where the internal pins 38 are connected by partitions 39. Connecting at least 2 or more pins can make a closer and more stable connection. The partition can connect both external 3 and internal pins 38. An additional effect is that the walls 27 can retain their straight shape.

By varying the ribs of the pins in size and width, click blocks can be made with varying adhesive strength that can be combined with each other.

Smaller blocks can be provided with pins with triple ribs 4 to connect smaller pieces with e.g. only 1, 2, 3, or 4 pins. As a result, the adhesion will be more excellent.

The wall pins 28 that are located on one side that connects to a connecting click block can take the form of a full pin in combination with the other wall pin 28 of the connected click block 26.

Advantages compared to the well-known hard Lego bricks are the following: 1

The hard Lego bricks come off immediately when folding a flexible base, such as a mat provided with pins 17. This is not the case with the click blocks 26 as described in the present invention. Since the structure and tolerances of the click blocks are less critical, it is possible to use plastics such as certain bioplastics unsuitable for hard click blocks such as the well-known Lego blocks. By using click blocks that all have the exact definition of internal pins, but where the external pins can vary in the number of ribs and/or dimensions, click blocks with different adhesive strengths can be combined with each other.

As shown in FIG 19 and 20, an additional preferred embodiment consists of tiles 29, partly equipped with external pins with double ribs 3, connected using a connection strip 30. In the proposed version, the connection strip 30 is also equipped with external pins with double ribs 3.

The goal here is that half of the connection strip 30 is provided for a first tile 29 and that a second tile 29 to be connected is clicked on the other part of the connection strip 30. This creates a connection in which the tiles 29 are perfectly aligned so that the tiles can still be easily disassembled and reassembled after assembly.

Fig 20 shows a preferred embodiment wherein the connection strip 30 is provided with an additional sealing strip 32 and adhesive strip 31. The adhesive strip 31 makes it possible to attach the connection strip 30 to a surface such as a floor, wall, or ceiling. The sealing strip 32 divides the connection strip into two parts where the 2 parts preferably have an equal number of pins 3. When clicking tile 29 into connection strip 30, the side of the tile 29 pushes against the adhesive strip 32. Preferably, the sealing strip 32 is composed of flexible material and equipped with an extra recess in which fits the side of the tile 29. This allows a waterproofing connection between tile 29 and adhesive strip 32.

The pins 3 are preferably only provided along the sides partially or entirely along the entire length of the side of tile 29 but can also be provided on tile 29 in other places or even over the entire bottom.

The connection strip 30 can be made of soft or hard material in combination with the tiles 29, which can also be built from hard or soft material. This depends on the desired application.

The pins 3 provided on tile 29 can be of the same material in one piece but can also be different elements that may be composed of a different material. The connection strip 30 can also have the shape of a corner element to connect the tiles 29 on the corner sides but also in a cross shape to connect, for example, four tiles 29, but it can also be a grid or frame in which fit the tiles 29.

Because the tiles 29 can be easily replaced after assembly, they can be equipped with illuminating elements, pressure gauges, and other elements that may or may not run on batteries.

An additional possibility is that connection strip 30 will be equipped with additional channels in which, for example, electrical lines can be accommodated.

Fig 21 shows a closure strip 33 for closing, for example, an orthosis.

The closure strip 33 comprises three parts: click element one 6, click element two 7, and flexible connections 37. The closure strip 33 is preferably supplemented with a bracket 34 to connect the closure strip 33 with an element such as an orthosis.

For the application of closure strip 33 as a closure element for an orthosis, closure strip 33 is preferably provided with an opening 35 with which the closure strip can be connected to one side of the orthosis. On the other side of the orthosis, bracket 34 can be attached. When closing the orthosis using closure strip 33, click element two 7 is inserted through slot 40 of bracket 34, and slot 40 is located at the level of the flexible connection 37 between click element one 6 and click element two 7.

To block closure strip 33, click element two 7 is clicked on the first click element. Pins 3 of click element two 7 are rotated 45° compared to the pins 3 of click element one 6.

If the longitudinal direction of the closure strip 33 is the x-direction and the transverse direction is the y-direction, then the pins 3 of click element two 7 and click element one 6 are preferably equidistant both in the x-direction and y-direction.

However, it is possible that the pins 3 on the click elements 6,7 itself have a different distance in the x-direction and y-direction. For example, by setting pins 3 in the x-direction further apart than the y-direction, the effect can be obtained whereby pins 3 of click element 6 and click element 7 can easily be clicked in and out of each other but when they are put under tension in the x-direction a solid connection is realised.

To ensure that click element two 7 is placed correctly on click element one 6, click element one 6 can be provided with a vertical wall 36.
