Description

Modular wall bar assembly

Technical Field

The invention relates to a wall bar assembly (wall bar assembly) which can be assembled from components which can be packed relatively compactly in the unassembled state.

Background

Wall studs are well known and have been manufactured by many different manufacturers for many years. Typically, it is mounted on the walls of gymnasiums and gymnasiums.

Publication number US4772011 discloses a wall bar assembly which is divided into parts that can be assembled together and disassembled. Rectangular plugs with corresponding recesses in the vertical elements are used to connect the modules vertically.

Publication US5156580 discloses a structure similar to a wall bar assembly. The two sections are connected by a tongue and groove arrangement in the vertical element.

Publication US4657242 relates to a doorway mountable wall bar assembly. The vertical elements are connected by a bolted connection extending through the overlapping portions.

Disclosure of Invention

According to the present invention there is provided a modular wall bar assembly comprising a plurality of modules, wherein each module comprises two vertical beams and a plurality of horizontal bars. The horizontal bars extend at their respective ends into bar receiving holes in the vertical beams. According to the invention, the vertical beams of at least two vertically connected modules are provided at their facing beam ends with a slotted recess provided with horizontal beam slots. The modular wall bar assembly also includes a module connecting and securing element including a connecting portion having an element recess configured to engage the beam channel. The module connecting and securing element further includes a set screw through hole configured to receive a set screw extending through the module connecting and securing element and into the vertical wall surface.

The vertical wall surface may typically be a wall inside or outside a house.

As used herein, terms like "horizontal" and "vertical" relate to the orientation of various features in an assembled state. The skilled person will appreciate that this orientation will of course be different when the modular wall bar assembly is in a non-assembled mode, for example in a package. For example, the term "vertical beam" refers to a beam structure that will have a substantially vertical orientation when the modular wall bar assembly is in an installed condition.

By means of the modular connection and fixing elements, it is possible to connect two vertical beams together and to fix the assembly to a wall. According to many embodiments, this connection and fixation can be achieved with only one element and one screw/bolt.

According to the invention, the element module connecting and securing elements arranged between two beams (and the upper and lower beams) will simultaneously engage the beam channels of the two beam ends connected together. Thus, one portion of the element will engage the first beam end and another portion will engage the second beam end.

The skilled person will understand that for embodiments where two modules are arranged laterally adjacent to each other, the two modules will share a vertical beam at their intersection. Thus, the term "each module comprises a vertical beam" also means an embodiment in which two horizontally adjacent modules share one single vertical beam.

In one embodiment of the present invention, the module connecting and fixing member may further include a spacing portion configured to be disposed between the rear of the beam and the wall. In such an embodiment, the vertical beams would be arranged at a distance from the wall surface. This distance may be selected by selecting the horizontal length of the spacer portion. In particular, the distance may be chosen such that a person can climb up the wall bar assembly by comfortably placing his feet on the horizontal bar, i.e. leaving enough space between the wall and the bar such that a person cannot climb using only the front of his feet. Furthermore, it is advantageous that the distance between the horizontal bar and the wall should not be too long, as this may pose a safety risk. In some embodiments, the desired distance between the horizontal bar and the wall may be about 8cm to 10 cm.

The end of the vertical beam may advantageously be provided with a fixing screw slot between the front face of the vertical beam and the grooved recess. When the beam ends are arranged together, their respective set screw slots will be aligned with each other and constitute holes or access openings for set screws.

The module connecting and securing element may further comprise an end edge terminating in an extension of the element recess. Advantageously, the end edge will determine the length of the element that can be inserted into the slotted recess of the beam end.

The horizontal bar may advantageously comprise a bar end provided with an insert having a semi-circular cross-section and a mating face. The rod attachment hole may then extend through the insertion portion and terminate at the mating face. The rod attachment holes may then be configured to align with the attachment bolt holes in the vertical beams.

In such embodiments, the assembly may further include a rod end piece having a mating face that may be configured to abut the mating face of the insertion portion and may present a workpiece aperture configured to align with the rod attachment aperture.

Furthermore, the mating face may advantageously extend along the axial distance, and then the rod attachment hole may be centrally arranged on the mating face.

By this feature, two adjacently arranged rods can be attached in the same rod receiving hole of one beam. That is, both rods may be attached to the same beam with only one rod attachment bolt.

In some embodiments, the modular wall bar assembly may further include a beam foot releasably attachable to the lower end of the lower beam. The beam foot may include a base, a foot slot configured to engage with the beam slot of the lower end of the lower beam, and a set screw through hole configured to receive a set screw.

In some embodiments, the modular wall bar assembly may further include a top end piece configured to attach to the top of the element on the top of the uppermost vertical beam. The tip end piece may also have a slotted end piece recess provided with an internal end piece groove configured to engage with an element groove of the module connecting and securing element.

In some advantageous embodiments, the vertical beams and/or the horizontal bars may comprise identical ends facing in opposite directions. With this embodiment, there is no need to consider which end of the beam or rod, respectively, is to be connected. For example, there is no risk of incorrect assembly of the wall bar assembly due to the vertical beams being installed "upside down" since both orientations will be correct.

Figures 1, 2 and 3 show a modular wall bar assembly 1 according to the present invention in an assembled state. In the present embodiment, the assembly 1 comprises three modules 3 arranged on top of each other in a vertically stacked manner. Each module 3 has two vertical beams 5 arranged at a mutual lateral distance. Four horizontal bars 7 extend between each vertical beam 5. The assembly 1 shown here therefore has twelve rods 7 arranged in parallel. Those skilled in the art will appreciate that each module 3 may comprise more or fewer bars, for example three bars 7 or five bars 7. Furthermore, the assembly 1 may comprise another number of modules 3, for example only two, four, five or significantly more.

Fig. 4 is a perspective view of a single vertical beam 5, which is not in an assembled state. For supporting the four bars 7, the beam 5 is provided with four bar receiving holes 9. The rod receiving hole 9 is configured to receive an end of the rod 7.

The vertical beam 5 has an upper beam end and a lower beam end 11, which in this embodiment are identical. At the beam end 11 there is an end face 13 facing in the longitudinal direction of the beam, i.e. facing in the vertical direction when in the assembled state. In the end face 13 there is a grooved recess 15. The grooved recess 15 includes a horizontal beam groove 17.

Although not visible in fig. 4, the lower beam end 11 of the illustrated beam 5 also includes such a grooved recess 15 with a horizontal beam groove 17.

When two vertical beams 5 are arranged on top of each other in an abutting manner, their facing grooved recesses 15 together form a cavity. Fig. 5 shows in perspective two vertical beams 5 arranged in this way. Also shown in fig. 5 is a module connecting and securing element 19 which is configured to be inserted into the cavity formed by the two facing slotted recesses 15.

A more detailed view of the module connecting and fixing element 19 is given in fig. 6 and 7. In this embodiment, the module connecting and fixing element 19 ("element") comprises a connecting portion 21 and a spacing portion 23. The connecting portion 21 is a portion of the element 19 that is configured to be inserted into the cavity formed by the grooved recess 15. The connecting portion 21 includes an element groove 25 configured to engage the beam groove 17 in the grooved recess 15. Thus, when the element 19 is inserted, it keeps the two adjacent vertical beams 5 from separating from each other. The element grooves 25 extend in a horizontal direction (when in an assembly mode) corresponding to the beam grooves 17 in the grooved recesses 15.

The element recess 25 extends as far as an end edge 27 on the element 19. Advantageously, the connecting portion 21 of the element 19 can be inserted all the way into the slotted recess 15 until the end edge 27 abuts a portion of the vertical beam 5.

In the perspective view of fig. 6, the front end of the fixing screw through hole 29 is seen on the connecting portion 21. The fixing screw through hole 29 extends through the entire element 19. Referring again to fig. 5, the set screw 31 is shown in a non-engaged state. The set screw 31 is configured to extend through the member 19 and into the wall (not shown) to which the modular wall bar assembly 1 is to be mounted.

Figure 8 shows the element 19 in a front cross-sectional view.

As shown in fig. 4, the beam end 11 further includes a set screw slot 33 through which the set screw 31 can pass. When the two beam ends 11 are joined together, their respective set screw slots 33 will align and constitute holes or openings for the set screws 31. As shown in fig. 4, the fixing screw slot extends between the front face or front edge of the vertical beam 5 and the slotted recess 15.

Referring again to fig. 3, 6 and 7, the spacer portion 23 of the element 19 will orient the vertical beam 5 at a distance from the wall corresponding to the length of the spacer portion 23. Thus, in some embodiments, the element 19 can be manufactured without any spacer portions 23, so that the vertical beam 5 substantially abuts the wall with its rear edge. Fig. 3 shows the vertical beam 5, the spacer portion 23 and the inner end of the fixing screw 31 in a side view.

As the skilled person will appreciate, the fixing screws may be in the form of bolts, wood screws or any suitable means for extending through the beam 5, the element 19 and into the fixed part of the wall.

Reference is now made to fig. 10 and also to fig. 5. The rods 7 extend into the rod receiving holes 9 of the beam 5 through their respective rod ends 35. In the illustrated embodiment, the rod end 35 includes an insert portion 37 having a semi-circular cross-section and has a mating surface 39. An end of the through-rod attachment hole 41 is arranged in the center of the mating face 39.

Fig. 9 shows a rod end piece 43 configured for its attachment to the insert portion 39 of the rod 7 within the rod receiving hole 9 of the beam 5. The rod end piece 43 also has a mating surface 45 configured to abut the mating surface of the rod 7. Further, the lever end piece 43 has a workpiece hole 47 aligned with the lever attachment hole 41 of the lever 7.

As shown in fig. 5, the rod 7 is fixed to the vertical beam 5 by a rod attachment bolt 49. The rod attachment bolt 49 is inserted from the rear side of the beam 5 through an attachment bolt hole, not shown. Further, it extends through the rod attachment hole 41 of the rod 7 and the workpiece hole 47 of the rod end piece 43. The workpiece hole 47 of the stem end piece 43 may advantageously be threaded so that the stem attachment bolt 49 remains in place. The rod attachment holes 41 of the rods 7 and/or the attachment bolt holes in the beam (not shown) may also be threaded.

Fig. 11 is a cross-sectional top view through the rod end 35 and the rod end piece 43 connected together in the rod receiving hole 9 of the vertical beam 5. The rod attachment bolts 49 (fig. 5) are not shown. As shown in fig. 11, the rod attachment hole 41 and the workpiece hole 47 are aligned and configured to receive a rod attachment bolt 49. Fig. 11 also shows attachment bolt holes 51 extending from the rear of the beam, through the rod receiving hole 9 and into the material at opposite sides of the rod receiving hole 9 for a distance. When inserted, the attachment bolt 49 holds the rod 7 in its assembled position and prevents the rod from rotating within the rod receiving bore 9.

Reference is now made to fig. 12, which is another cross-sectional top view through the rod end 35 of the rod 7. In this view, the rod attachment bolt 49 is not shown. In the embodiment shown in fig. 12, two rods 7 have been inserted into the rod receiving bore 9 and have been fastened with a common rod attachment bolt 49. The stem end piece 43 is not present.

The attachment arrangement shown in fig. 12 is applied when arranging the module 3 transversely with respect to another module. Such an embodiment is depicted in fig. 13, where one vertical stack of modules 3 comprises three modules 3 and the adjacent one comprises two modules 3. The modules 3, in which the bars 7 share a vertical beam 5, will be arranged in a common beam 5 according to the solution shown in fig. 11. In a beam 5 that is not shared by two modules 3, the rods are advantageously attached to the beam 5, i.e. with the rod end pieces 43, according to the arrangement shown in fig. 11.

Fig. 14 is a perspective view of the beam foot 53. The beam foot includes a base 55 configured to rest on the floor or ground, adjacent to a wall. In addition, beam foot 53 includes a foot slot 57 corresponding to element recess 26 of element 19. Thus, the foot slot 57 fits into the beam slot 17 of the slotted recess 15 in the beam end 11.

Reference is also made to fig. 15 and 16, which show the beam foot 53 in front and top views, respectively. Like the module connecting and fastening element 19, the beam foot 53 also has a fastening screw through opening 59. The beam foot 53 can thus be fixed to the lower end of the vertical beam 5 in the same way as the element 19 described above. In this regard, the base 55 of the beam foot 53 becomes part of the vertical beam and the foot slot 57 becomes part of the element recess 25 of the element.

Fig. 17 and 18 show the tip piece 61 in perspective view and rear view, respectively. The tip end piece 61 is configured to attach on top of the element (which is arranged on top of the uppermost beam 5) 19. Tip end piece 61 has a slotted end piece recess 63 provided with an internal end piece groove 65. The tip end piece 61 is configured instead of the upper beam 5. Thus, the inner end piece groove 65 corresponds to the beam groove 17 of the grooved recess 15 of the beam end 11.
