Description:
CONNECTORS INTEGRATED INTO INTERCONNECTED MATS

DESCRIPTION OF THE INVENTION

Field of Technology

Connectors for interconnecting mats; interconnecting mats; floor mats; connection of mats; securing of mats; double-sided connection; pedestrian mats; load-bearing road mats; surface protection mats; helicopter landing pads.

Technical Problem

Temporary road or ground protection mats need to be interconnected at the construction site to provide a stable working surface. Typically, the connectors and associated components must be delivered to the site separately, where individual components can be lost. Assembly with non-integrated components takes time, and if connector components are lost then mats cannot be assembled. In addition, there are products known on the market that are designed in such a manner that the connectors can be inserted or operate only from one predetermined side of the mat.

The connector system in this invention is fully integrated into the mats, avoiding the need for separate connector components and allowing the mats to be connected from both sides. In this way, the basic mats can be used with either surface uppermost, and without the need to disassemble and reposition the connector. State of the Art

There are several solutions for the interconnection of mats available on the market. The existing solutions are designed as follows:

the connectors are inserted at construction sites or at the points of assembly of interconnecting mats; or

the mats are interconnected by using a bolting assembly, which requires the use of power or electrical tools to assemble the mats instead of partially rotating a hand tool.

Furthermore, the existing solutions do not allow the connector to be connected on both sides or the connector is not integrated, and the components may be lost. If the components are lost, the assembly is disrupted, since the road/platform cannot be assembled. Lost components also present a pollution hazard and a risk of being consumed by animals or a risk of injury or damage when mowing crops or can become foreign objects on the road surface with the potential to cause damage.

Description of New Invention

The subject matter of the invention is a connector integrated into interconnected mats, solving the technical problems of:

connecting the interconnecting mats 2;

respective availability of the connector for interconnecting mats 1 to connect the interconnecting mats 2.

The technical problem is solved in the following way:

the interconnecting mats 2 are constructed in such a manner that they have mat overlaps 3 and mat underlaps 4 constructed as follows:

• the upper mat overlap 3 is constructed along the edges of two adjacent sides of the interconnecting mat 2 in such a manner that the thickness of the interconnecting mat 2 on the mat overlap 3 is smaller, preferably by approximately one half of the thickness of the interconnecting mat 2;

• the lower mat underlap 4 is constructed along the edges of two adjacent sides of the interconnecting mat 2 in such a manner that the thickness of the interconnecting mat 2 on the mat underlap 4 is smaller, preferably by approximately one half of the thickness of the interconnecting mat 2;

the mat overlaps 3 and the mat underlaps 4 on the interconnecting mats 2 are provided with holes on interconnecting mats 6 through the interconnecting mats 2, with the axis of the holes on interconnecting mats 6 running perpendicular to the plane of the interconnecting mats 2;

the connector for interconnecting mats 1 is integrated in the edges of the interconnecting mat 2, namely in the mat overlaps 3 and/or the mat underlaps 4, thus being always available for connecting the interconnecting mats 2;

the connector for interconnecting mat 1 used for locking or unlocking the connection is limited by at least one securing plate 7 on the side of the connector head 15;

the connector for interconnecting mat 1 is turned by an angle of 0° to 180°, preferably by an angle of 90° or approximately 90°, for locking.

The mat overlaps 3 and the mat underlaps 4 on the interconnecting mats 2 are provided with recesses for the plates 5, whereby the recesses for the plates 5 on the interconnecting mats 2 are located in such a manner that when assembling the interconnecting mats 2, the recesses for the plates 5 on the mat overlaps 3 and the mat underlaps 4 are positioned one above the other. Holes on interconnecting mats 6 are provided perpendicular through the recesses for the plates 5. The recesses for the plates 5 can be constructed in any way, but preferably they are constructed as deepening or grooves.

The interconnecting mats 2 are assembled into a larger unit or surface, forming a load-bearing base for carrying loads, for example work pad areas, roads, pathways, helicopter landing pads and similar. The dimensions of the mat edges are optional, but preferably the mat overlap 3 and the mat underlap 4 have the same width and thickness, preferably one half of the thickness of the interconnecting mat 2.

The connectors for interconnecting mat 1 in this invention are fixed to one of the edges of the interconnecting mat 2, namely on the mat overlap 3 or the mat underlap 4. The connectors for interconnecting mat 1 are integrated into the interconnecting mats 2 during the production of interconnecting mats 2, which prevents the connectors for interconnecting mat 1 from being lost and ensures faster connection and assembly of the interconnecting mats 2.

The shaped recess for connector tools 13 can be positioned only on the side of the connector head 15, but preferably the shaped recess for connector tools 13 is positioned on both sides of the connector for interconnecting mat 1, namely on the connector head 15 side and the connector foot 12 side or the shaped recess for connector tools 13 runs through the complete connector for interconnecting mat 1 along the connector axis. The connector tools used for turning the connector for interconnecting mat 1 into locked or unlocked position can be any tools, preferably an Allen key. The connectors for interconnecting mat 1 can be turned into locked position from the upper side of the connector for interconnecting mat 1 or from the upper or lower side of the connector for interconnecting mat 1. The top of the connector head 15 can be equipped with a slot on the connector head 14, allowing the connector for interconnecting mat 1 to be turned into unlocked or locked position by using a large screwdriver or similar tool. During the assembly, the connector for interconnecting mat 1 can be positioned with the connector head 15 facing upwards or the connector head 15 facing downwards.

The interconnecting mats 2 can also be assembled in such a way that the connector head 15 of the connector for interconnecting mat 1 is securely fixed to the mat underlap 4, and the connector foot 12 is visible on the upper mat overlap 3. The interconnecting mats 2 can be made of any material, but preferably they are made of plastic materials, metallic materials or wood materials.

The connector for interconnecting mat 1 is constructed in such a manner that, viewed in the direction of the axis through the connector, the circular cross-section on the upper half is preferably of the same diameter, except on the circular groove within the connector body 11, where the connector for interconnecting mat 1 has a smaller cross-section because the connector for interconnecting mat 1 is fixed to the interconnecting mat 2 with at least one securing plate, preferably with two securing plates 7. The dimension of the circular groove within the connector body 11 corresponds in shape to the dimensions on the securing plates 7 ; the outer diameter of the circular groove within the connector body 11 coincides with the inner diameter on the securing plates 7, and the height of the circular groove within the connector body 11 coincides with the thickness of the securing plates 7. The cross-section in the lower part of the connector for interconnecting mat 1 on the side of the connector foot 12 is smaller, and the connector foot 12 is positioned at the bottom of the connector. The connector foot 12 can be flat on surfaces where it fixes the interconnecting mat 2 or it can be shaped in such a way as to ensure a more secure connection in the locked position.

The connector for interconnecting mat 1 is preferably made up of one part; however, it may consist of two or more parts. One of the variants of assembly of the connector for interconnecting mats 1 is at the point of the circular groove within body of connector 11.

On the edge of the mat, namely the mat overlap 3 or the mat underlap 4, to which the connector for interconnecting mat 1 is fixed on the side of the connector head 15 by using at least one securing plate 7, there is a hole on interconnecting mat 6 which is at a right angle to the interconnecting mat 2, preferably having a circular cross-section and preferably being of the same diameter as the diameter of the upper half of the connector for interconnecting mat 1 on the side of the connector head 15. On the other edge or the edge of the other interconnecting mat 2, to which the connector for interconnecting mat 1 is not securely fixed, and where the axis of the hole on interconnecting mat 6 coincides with the axis of the hole on interconnecting mat 6 with a circular cross-section, the hole with a non-circular cross-section is constructed in such a manner that the lower part of the connector for interconnecting mat 1 or the connector foot 12 passes through the edge of the mat, and when the connector for interconnecting mat 1 is turned, preferably by 90°, the connector foot 12 rotates and forms a secure connection of the interconnecting mats 2. The assembly is constructed with a tolerance, which means that enough friction is created between the connector for interconnecting mat 1 and the interconnecting mats 2 in the closed position in order to prevent opening during use. Furthermore, the production tolerances take account of the expansion of individual components due to thermal expansion of materials. The connector for interconnecting mat 1 can be made of any material, but preferably it is made of metallic or plastic material. The connector for interconnecting mat 1 is one side limited with at least one securing plate 7, and on the other side preferably with at least one receiver plate 9. If the interconnecting mats 2 are made of metal, it is possible to construct the edge of the mat through which the connector foot 12 passes without using the receiver plate 9, since in that case, the material of the interconnecting mat 2 is sufficiently strong to bear the load without using the receiver plates 9.

The securing plates 7 and the receiver plates 9 are fixed in the recess for the plate 5 in any way, preferably by screws. The contact surface between the mat overlap 3 and the mat underlap 4 bears the load evenly over the surface. The securing plates 7 and the receiver plates 9 can be made of any material, but preferably they are made of metallic material.

The material of the receiver plate 9 can be thicker on the external surface to allow the connector foot 12 to pass through the lower interconnecting mat 2 in case of fixing to a hard base, for example concrete, which enables turning the connector foot 12 into locked position. In addition, instead of using thicker material to ensure appropriate distance for fixing at least one receiver plate 9, fasteners with higher heads are used, preferably screws with higher heads. When using the interconnecting mats 2 made of metal, the material can be thicker on the lower side of the interconnecting mat 2 in the immediate vicinity of the hole on interconnecting mat 6 which is positioned on the interconnecting mat 2.

The essence of the invention is further explained below with the description of the embodiment and attached figures, whereby the figures are part of this patent application and show the following:

Exemplary embodiment:

The interconnecting mats 2 have mat overlaps 3 and mat underlaps 4 which are constructed as follows:

the upper mat overlap 3 is constructed along the edges of two adjacent sides of the interconnecting mat 2 in such a manner that the thickness of the interconnecting mat 2 on the mat overlap 3 is one half of the thickness of the interconnecting mat 2;

the lower mat underlap 4 is constructed along the edges of two adjacent sides of the interconnecting mat 2 in such a manner that the thickness of the interconnecting mat 2 on the mat underlap 4 is one half of the thickness of the interconnecting mat 2; the mat overlaps 3 and the mat underlaps 4 on the interconnecting mats 2 are provided with holes on interconnecting mats 6 through the interconnecting mats 2, with the axis of the holes on interconnecting mats 6 running perpendicular to the plane of the interconnecting mats 2;

the connectors for interconnecting mats 1 are integrated in the mat overlaps of interconnecting mats 2, thus being always available for connecting the interconnecting mats 2;

the connector for interconnecting mat 1 is turned through an angle of 90° or nearly 90° for locking.

The mat overlaps 3 and the mat underlaps 4 on the interconnecting mats 2 are provided with recesses for the plates 5. The recesses for the plates 5 are constructed as deepening or grooves.

The interconnecting mats 2 are assembled into a larger unit or surface, forming a temporary roadway on a construction site. The connectors for interconnecting mat 1 are integrated/embedded into the interconnecting mats 2 during production.

The shaped recess for turning tools 13 is positioned on both sides of the connector for interconnecting mat 1. The turning tools used for turning the connector for interconnecting mat 1 into locked or unlocked position is an Allen key. The connectors for interconnecting mat 1 can be turned into locked position from the upper or lower side of the connector for interconnecting mat 1. The top of the connector head 15 is equipped with a slot on the connector head 14, allowing the connector for interconnecting mat 1 to be turned into unlocked or locked position by using a large screwdriver or similar tool.

The interconnecting mats 2 are made of plastic material. The upper half of the connector for interconnecting mat 1 has a circular cross-section of the same diameter, except on the circular groove within the connector body 11, where the connector for interconnecting mat 1 has a smaller cross-section because the connector for interconnecting mat 1 is fixed to the interconnecting mat 2 with two securing plates 7. The cross-section in the lower part of the connector for interconnecting mat 1 on the side of the connector foot 12 is smaller, and the connector foot 12 is positioned at the bottom of the connector.

On the edge of the mat, to which the connector for interconnecting mat 1 is fixed on the side of the connector head 15 by using the securing plates 7, there is a hole on interconnecting mat 6 which is at a right angle to the interconnecting mat, having a circular cross-section of the same diameter as the diameter of the upper half of the connector for interconnecting mat 1 on the side of the connector head 15. On the other edge or the edge of the other interconnecting mat 2, to which the connector for interconnecting mat 1 is not securely fixed, and where the axis of the hole on interconnecting mat 6 coincides with the axis of the hole on interconnecting mat 6 with a circular cross-section, the hole with a non-circular cross-section is constructed in such a manner that the lower part of the connector for interconnecting mat 1 passes through the edge of the mat, and when the connector is turned, preferably by 90°, the connector foot 12 rotates and forms a shaped connection of the interconnecting mats 2. The assembly is constructed with a tolerance, which means that enough friction is created between the connector for interconnecting mat 1 and the interconnecting mats 2 in the closed position in order to prevent undesirable opening during use. The connector for interconnecting mat 1 is made of metallic material.

The movement of the connector for interconnecting mat 1 is one side limited with two securing plates 7, and on the other side with one receiver plate 9. The securing plates 7 and the receiver plate 9 are fixed in the recess for the plate 5 by screws. The securing plates 7 and the receiver plate 9 are made of metallic material.

It is self-evident that the above described invention can be also used in other particular forms without changing the substance of the invention.
