Field of the Invention

[0001] The present invention relates to building construction, more particularly to an adjustable threaded rod elements for connecting or mounting construction elements, such as in combination with a pipe hanger system and to methods for connecting or mounting such elements, as well as method for producing such elements. More particularly invention relates to an element for a pipe hanger system , i.e. one and/or two threaded rod(s) and a pipe hanger system comprising said element for supporting water, gas, or waste pipes by attachment to various supports, e.g. concrete supports and wooden supports e.g. floor joists.

Background of the invention

[0002] In constructing houses and buildings with any framework, such as a wooden framework or concrete framework it is common to run construction elements such as pipes of various types beneath or above or in parallel for example a number of spaced apart, parallel floor joists. It is not practical to make cut-outs, such as drilling aligned holes in the joists or other construction elements for guiding construction elements such as a pipe through such cut-outs. Drilling is too time consuming and weakens the load capacity the construction framework and may be violations of local building codes. [0003] One common way of suspending construction elements such as pipes from other construction elements such as joists is to utilize segments of sheet metal, a threaded metal rod, or plastic strapping having a series of holes punched therethrough. Segments of this strapping, or parts attached thereto are wrapped around the pipe at spaced intervals and nailed to the joists bottom. The pipe is still somehow free, in many cases, to more upwardly, horizontally, or laterally, which is rather undesirable. [0004] Another common method of installation of piping requires the utilization of individual pipe hangers. These typically have a J- type configuration and are made of metal or plastic including rubber around the pipes. The longer leg, rod or stem of the J-type hanger is nailed to the stud and the pipe is received in the curved portion of the hanger. The J-type hangers must be manufactured in different sizes and various lengths to accommodate various pipe diameters and how long the suspension is to be, various pipe diameters for waste water are the commonly known in Denmark to be of diameters on 110 mm and 160 mm. Using known devices and methods for mounting construction elements like piping in buildings or construction sites faces several challenges firstly known devices made from corrosion resistant metal of fixed dimension are expensive make and once made they are difficult to fit or adjust to the many different types of construction elements to be fitted into a building. Further known devices comprising threading are sensitive to dirt and other materials present during constructions which can get caught or entangled with the threading and thereby obstructing or even blocking its function.

[0021] The present invention provides for improved mounting of one construction element onto another construction element and offers solutions to challenges and drawbacks of the art, more specifically by providing in a first aspect an adjustable threaded rod element (10) for mounting a first construction element (50) on a second construction element (51) comprising, on a majority of its longitudinal axis, an outer thread (18), and in one end an inner (female) connector opening (15), and in the other end an outer (male) connector protrusion (12), wherein the inner connector opening (15) and the outer connector protrusion (12) are adapted to fit into each other so that the outer connector protrusion (12) of one threaded rod element can connect and lock into the inner connector opening

(15) of another threaded rod element; wherein the thread (18) has one or more longitudinal sections

(16) without threading. The present inventors have found that the one or more longitudinal sections (16) without threading prevents or reduces dirt at a construction site from obstructing the functioning of the threading and thereby the use of the threaded rod (10) for mounting construction elements. Sections with no threading may be provided for by cutting or casting groves in the threading in the longitudinal axis of the rod (10), which are sufficiently wide and spacious to catch and contain any pebbles, sand, gravel, dust or the like (dirt) getting entangled in the threading during operation. [0022] In some embodiments the treaded rod (10) may include 2, 3, 4 or more longitudinal sections (16) without threading, where the optimal number of sections without threading depend on the dimension of the threaded rod (10) and the threading.

[0023] The inner (female) connector opening (15) and the outer (male) connector protrusion (12) for connecting two or more threaded rods (10) may be a "click and lock" system or more preferable comprise matching threads of a smaller dimension than the thread (18), adapted so that one threaded rod element can connect and lock into another threaded rod element by screwing the threaded outer (male) connector protrusion (12) of one threaded rod element into the threaded inner (female) connector opening (15) of another threaded rod element. The threading of the inner (female) connector opening (15) and the outer (male) connector protrusion (12) may also have one or more, such as 2, 3, 4 or more longitudinal sections (16) without threading to provide for resistance to dirt obstructing the screwing function of the threading.

[0024] The outer thread (18) is present on a majority or most of the longitudinal axis of the treaded rod (10). In this context a majority means more than 50%, such as 75%, such as 80% such as 90%, such as 95% and up to and including 100% of the longitudinal axis of the treaded rod (10) any preceding claim, wherein the threaded rod element (10) comprises an outer thread (18) on its entire longitudinal axis.

[0025] In a further refinement the threaded rod element may comprise a visible length indicator or marking (13). Such an indicator is very useful for example when measuring out a desired length of the threaded rod, especially when the mounting of construction elements require the coordinated application of multiple rods, such as when mounting longer stretches of pipes or wires.

[0026] The threaded rod element (10) can be made of any desirable material, but as opposed to many known elements of similar function, the threaded rod element (10) of the invention can be made from a material comprising a synthetic polymer, which is suitable for casting by mould injection. This material may optionally be reinforced by organic or inorganic fibers and/or other additives to provide suitable properties of the rod matching the intended use of the rod. Properties like wear and tear resistance and resistance to environmental conditions such as radiation (including sunlight), temperature, pH or other chemical influence, may be modified by choice of polymer and/or additives. In one embodiment the synthetic polymer is selected from polyamide (nylon) 66, Polyamide (nylon) 6, polypropylene or polyethylene. In another embodiment the additives include inorganic fibers such as glass fibers or any composites thereof.

[0027] The first construction element (50) which can suitably be mounted by use of the threaded rod (19) of the invention includes but is not limited to pipes, wires, hoses, ducts, rails and/or guides, while second construction element (51)s onto which the first construction element (50) is mounted suitably includes but is not limited to floors, ceilings, walls, joists, beams, and/or pillars of a construction or building.

[0028] In a further aspect the threaded rod (10) of the invention is used together in combination with additional elements in a system for mounting the first construction element (50) onto the second construction element (51). Accordingly, also provided for herein is a mounting system (10, 20, 30) for mounting a first construction element (50) on a second construction element (51) comprising the threaded rod element (10) of claims Error! Reference source not found, to [0026] , a joint element (20) and a flexible strap element (30); wherein the joint element (20) has a cubic, cuboid, trapezoid frustrum or conical frustrum structure and comprises i) a first surface (40), optionally being the base surface or the surface opposite to the base surface, comprising an inner threading (24) adapted to connect to and match with the outer thread (18) of the threaded rod (10), ii) a second and a third lateral and opposite positioned surfaces (41), each comprising one or more connector openings (27, 28) adapted to connect with the strap element (30), and iii) a fourth surface (42) adapted to engage with the first and/or second construction element (51); and wherein the strap element (30) comprises two opposite end portions (39) each end portion comprising one or more protrusions (37, 38) adapted to fit into the one or more openings (27, 28) of the joint (20) allowing the two end portions (39) of the strap (30) to connect and lock into the second and third surface of the joint (20). While the joint element (20) may have a cubic or box structure, shapes of a truncated pyramid or conus ("frustra") are preferred because a slope angle of the lateral (side) surfaces offers not only easier attachment of the strap, but also improved locking and load carrying properties of the strap once attached to the joint. The first, second and third surfaces of the joint element (20) need not be completely plane but can have a certain level of curvature as can be seem from figure 5.

[0029] For attaching the strap element (30) to the joint element (20) the strap element (30) may comprise in each of its end portions (39) at least one protrusion (36) angled and dimensioned on the strap to carry a majority of the load which the first construction element (50) applies on the strap element (30) and at least one protrusion (37, 38) angled and dimensioned for locking the strap end portion (39) to the joint element (20). In one embodiment the strap element (30), in each of its end portions (39), comprises three protrusions (36, 37, 38) of which one protrusion (36) is angled and dimensioned to carry a majority of the load which the first construction element (50) applies on the strap element (30) and the two other protrusions (37, 38) are angled and dimensioned for locking the strap end portion to the joint element (20).

[0030] The fourth surface (42) of the joint element (20) facing the mounted first construction element (50) is preferably curved, angled or otherwise shaped to match the curves, angles or other shape of the first construction element (50) to increase grip of the strap element (30) and the joint element (20) on the first construction element (50). Accordingly, where the first construction element (50) is a pipe the fourth surface (42) preferable have a curvature matching the outer circumference of the pipe. [0031] The strap element (30) have in particular embodiments a dimensional length so that it when it is attached to the joint element (20), the strap (30) and the joint (20) together span, enclose, encircle and/or tightly fit in the approximately circular cross section the a first construction element (50) of an approximate tubular dimension as described herein, optionally having a circumference corresponding to a circular diameter of 10 to 500 mm, such as 50 to 250 mm, such as 100 to 200 mm.

[0032] The mounting system of the invention may further comprise a second joint element (20) connected to the threaded rod element (10) at the opposite end of where the first joint element (20) is connected to the threaded rod (10), said second joint element (20) adapted to be fastened on the second construction element (51) by suitable fastening means, including but not limited to screws, nails or adhesives. The joint element (20) may therefor also be equipped with a hole or opening (26) for fixing the joint element (20) by means of a nail or screw.

[0033] Moreover, the present invention has the objects of - just to name a few - to comprise few mechanical parts, to improve the mentioned leg, rod or stem, to be cheap to manufacture, to be of the same material throughout, providing for simple adjustment on the building site, i.e. either shorter or extendable to a longer length, to be low in weight, to be fast and easy to install, to require less or no maintenance, and to be simple to adjust, shorten and to extend if need be, for the user and having a good guidance for enable cutting length so as to achieving accurate graduated heights.

[0034] Moreover, the present invention, has the important object of being usable in environments and surrounding, where there is a danger that very small dirt particles, such as tiny pebbles, sand, gravel and dust get into the threads of the present inventions element: the threaded rod(s), while still allowing that the threads are usable, i.e. the threads can be used to screw two parts such as two rods together, or the rod to another mating part.

[0035] These objects are achieved in that the invention has been given the features as defined in the claims.

[0036] Embodiments of the invention are described in greater detail in the following.

[0037] Described herein are specific embodiments of that which the inventor(s) considers at present to be useful modes of fabrication, assembly, and operation for carrying out the invention. These are necessarily narrow embodiments and cover only a few of the many possible ways to practice the invention. Therefore, it is to be understood that the invention itself is actually much broader in scope, as set forth in the invention defined by the appended claims.

[0038] The following figures are shown in order to explain the invention in details and by means of various parts and embodiments of the inventions' threaded rod and pipe hanger system along with actually two identical rods, one threaded rod is shown for the pipe hanger system.

[0039] Figure 1 shows one embodiment of an assembled pipe hanger system.

[0040] The pipe hanger system (10, 20, 30) comprising a threaded rod (10), a joint (20) and a strap (30). [0041] The threaded rod (10) is explained in this context as one important and adjustable element of the pipe hanger system.

[0042] In principle in one embodiment one rod (10) may be used solely, however when need arises for a longer suspension of the pipe two - or more - threaded rods may be connected to one another. This is possible, see figures 1, 2 and 4, in that the outer thread (12) of one threaded rod (10) can be screwed into the inner thread (15) of another rod.

[0043] Likewise, in one embodiment three threaded rods may be connected to each other.

[0044] The pipe hanger system (10, 20, 30) is in one embodiment intended for mounting a pipe encircled by the strap (30), which strap (30) holds, suspends and keeps the pipe in proper place. The pipe may be a pipe for water, gas, waste or a pipe for central heating or for cooling a house, an apartment, a story building etc.

[0045] Figure 2 shows that in one embodiment a threaded rod belonging to the pipe hanger system. The threaded rod (10) having on its one end (14), here the upper end an outer thread (14), the outer thread (14) of the threaded rod (10) has a dimension enabling it to be screwed into a corresponding mating inner thread (24) of the upper side of a joint (20), see figure 1 and 5, whereby the threaded rod (10) is fixed to the joint (20).

[0046] Figure 3 shows that in one embodiment an end of the threaded rod belonging to the pipe hanger system. The threaded rod (10) generally has an outer thread (18) at the most of its length, however it has on its end (12), here the lower end (12) a smaller dimensioned outer thread (12). On the opposite end of the rod (10), i.e. inside the bigger outer thread (14) (which has the same dimension as the thread (18)) of the threaded rod (10), see figure 2 and 4 is another inner thread 15. This inner thread 15 allows two threaded rods (10) to be mounted to one another in that the small dimensioned outer threaded end (12) of one threaded rod (10) is screwed onto the inner thread (15) on the end (14) of another threaded rod (10). This allows the pipe hanger system to have an element as a (almost) double length threaded rod (10), comprising two mounted together threaded rods (10), mounted to the joint (20). Likewise, this further allows that the pipe hanger system to have a longer element in the form of a (almost) triple length threaded rod (10), which rod (10) comprises three mounted together threaded rods (10) joined by two mountings (14) and (15) to one another.

[0047] In figure 2, 3 and 4 it is shown by (13) that in one embodiment for every one centimeter there is a visible indication (13) - as a partly circular mark - for every centimeter length of the shown threaded rods (10). This has the advantage that the threaded rod or rods (10), if need be, can be shortened (cut over, broken, sawed) at any centimeter length by shortening, e.g. by means of a saw, a knife or a similar cutting tool it at the visible indication (13).

[0048] Figure 4 shows one embodiment of the other end of the threaded rod belonging to the pipe hanger system. The threaded other end (14) of the threaded rod (10) is to be screwed into the inner thread (24), see figure 1 and 5, of the upper side of the joint (20). By doing so the threaded rod (10) is screwingly fixed into and to and on the top side of the joint (20)

[0049] Figure 5 shows one embodiment of a joint belonging to the pipe hanger system. The joint (20) has a pair of three openings 27, 28 on its two sides, and the joint (20) has an inner thread 24 on its upper side, and a through going hole 26 on its bottom side, the hole 26 is intended for receiving a screw or a nail enabling the joint (20) to be nailed or screwed on another building part, e.g. a ceiling, a room divider or a like fixed horizontal structure.

[0050] In one embodiment a pair of three protruding pins (36, 37, 38) of the strap (30), see figures 6 and 7, is in one embodiment adapted to fit into the corresponding mating pair of the three openings (27, 28, 29) of the joint (20). This fitting of six (= two times three) pins into six holes (of the joint (20)) allows the two opposite ends (39) of the strap (30) to be tightly and potentially irreversibly locked to and into the joint (20), when the straps' (30) pair of the three protruding pins (36, 37, 38) is pushed and forced into the two times three openings (27, 28, 29) of the joint (20), and hereby the strap (30) mounts and holds the pipe, if the pipe was present in and surrounded by the strap (30) before the straps (30) two ends (39) was locked into six openings (27, 28, 29) of the joint.

[0051] Figure 6a shows a first embodiment of a strap belonging to the pipe hanger system. This small strap is intended for pipes with pipe diameters of 110 mm.

[0052] Figure 6b shows a second embodiment of a strap belonging to the pipe hanger system. This bigger dimensioned strap (30) is intended for pipes with pipe diameters of 160 mm. The two straps (30) - from figures 6 and 7 - each have a pair of at three protruding pins 37, 38 on its two opposite ends (39). The pins 37 and 38 make it possible to mount the strap (30) - with a pipe inside its perimeter - to the joint (20) as shown in figure 1. Of course, thereby the strap (30) mounts and holds the pipe and surrounds it tightly by means of the surrounding now mounted strap (30) to the joint (20).

[0053] Subsequently in one embodiment the assembled pipe hanger system with a pipe inside the strap (30) fulfils its purpose, namely to mount the pipe in a proper position, when the end (12), though cut of a few centimeters, of the threaded rod (10) is beforehand fixed to another joint (20) mounted (e.g. by a nail or a screw) e.g. to the underside of a support, e.g. a concrete support, wooden support or a floor joist. By cutting e.g. two centimeter of the end (12) of the threaded rod (10) (along with the inner thread 15) a bigger outer thread - corresponding to the dimension of the outer thread (14) of the other end - of the threaded rod (10) is available and thus mountable to the inner thread (24) of the other mentioned joint (20), which joint (20) can be nailed or screwed to the underside of the support, since the diameter of the hole (26) of the joint (20) is big enough to be used to direct and mount a screw or a nail into the support. [0054] Moreover, in one embodiment by cutting a chosen part of the rods' length, e.g. some centimeter of any of its two ends (12, 14) of the threaded rod (10) it still maintains it purpose, however with a shorter desired length.

[0055] It is important, and in the spirit or gist of the invention, that in one embodiment all the discussed outer threads (12, 14, 18) of the threaded rod (10) have four longitudinal sections (16) where the thread is not fully present, as shown approximately 25 % of the threads, see figures 2, 3 and 4, is not present, but simply missing.

[0056] However, in one embodiment the element in the form of one or the two threaded rods (10) may have in more embodiments one, two, three or even more than four longitudinal sections (16) where the mentioned threads (12, 14, 18) are not fully present.

[0057] Therefore, any of the above embodiments, has the big advantage that the outer treads (12, 14, 18) - of the threaded rod(s) (10) - is/are well applicable (during managing, handling and mounting of e.g. pipes) in environments where very small dirt particles, such as tiny pebbles, sand, gravel and dust are present, since - even if the small dirt particles are by mistake or simply by handling (the inventions three parts) present in the threaded rod's (10) threads - then the outer threads (14, 18) can still mate with and be screwed into the inner thread (24) of the joint (20). Consequently, and likewise, in one embodiment the small outer thread (12) (of one rod (10) or of two extended rods, (12) can still mate with and be screwed into the inner thread (15) of another similar rod (10), when small dirt particles are present in one and/or two threads of the two threads (12) and (15).

[0058] While the foregoing embodiments of the invention are at present considered to be preferred, it is understood that numerous variations e.g. in construction and the dimensions of the rod, joint and strap, the materials thereof, be made therein by those skilled in the art and it is intended to cover in the appended claims all such variations and modifications as fall within the true spirit/gist and scope of the present invention.

[0059] The invention further provides a method for mounting the first construction element (50) onto the second construction element (51) comprising connecting the first construction element (50) and the second construction element (51) with the mounting system of the invention. Typically, the practitioner of the present invention would fist fix a joint (20) on the second construction element (51) and thereafter measure out a desired length of the threaded rod (10) or multiple rods connected together and screw one end of the (combined) rod into the joint fixed to the second construction element (51). Thereafter the practitioner would typically attach a further joint (20) to the other end of the (combined) rod, place the first construction element (50), such as a pipe, against the fourth surface (46) of the joint (20) and fixing it to the joint by strapping and locking the strap (30) around it. [0060] The invention further provides a method for producing one or more of the adjustable threaded rod element (10) of claims 1 to 8, the joint element (20) of claims 10 to 14 or the strap element (30) of claims 10 to 14 comprising providing a synthetic polymer of claims 7 to 8 and injecting the synthetic polymer into a mould and releasing threaded rod element (10), the joint element (20) or the strap element (30) from the mould.
