Description

The present invention relates to a self-supporting suspension device for hanging shelves, baskets or similar devices, with or without the help of brackets, consisting of at least two racks, which in their raised position are oriented essentially vertically, supports, which are part of each rack and made in the form of an elongated element, which when assembled with a corresponding rack is located essentially at right angles relative to the longitudinal direction of the rack, and the stabilization element, which th adapted to be attached to said uprights to provide a durable interconnection of a plane which is substantially at right angles with respect to said supports.

The invention also relates to a method for assembling this self-supporting suspension device.

Self-supporting shelf-mounted sets of shelves for storage are already known in a variety of options. All of them are united by the fact that they contain end-assembled end elements and a design for lateral stabilization of a set of shelves. Commonly used metal profiles, such as flat rods, metal rods or thin metal wires, which are secured diagonally in adjacent end elements. Often also used devices such as scissors, made for this purpose and secured in a similar manner. The rear elements, made as a whole, adapted for fastening with nails to adjacent end elements, perform the same function. Various shelves are placed on the shelf brackets, which are attached to the racks of the end elements. As a rule, many holes are drilled in the racks, which are designed to install shelf brackets. Brackets for shelves are made in the form of pins, corner profiles containing pins, or wire clamps.

Another type of self-supporting set of shelves for storage contains end elements, which consist of a pair of metal racks that are connected to each other using screwed, crossed flat rods or similar elements, and in some sets of storage shelves they are stabilized with screwed shelves.

These self-supporting sets of storage shelves combine the fact that they require a rack in each corner of the shelves, and the fact that assembling these sets of storage shelves requires a lot of pins and / or bolts. When assembled in an upright position, they are also usually laborious and difficult to assemble. In addition, they are intended only for shelves, but not for wire baskets, hangers for clothes, hangers for trousers and similar devices.

The aim of the present invention is to provide a self-supporting suspension device that is convenient for assembly and does not require screw or bolt connections or similar joints, which is stable, contains a small number of elements and requires minimal space for assembly.

Another objective of the present invention is to provide a self-supporting suspension device in which shelves, wire baskets, clothes shelves, trouser racks and the like can be easily fixed with the possibility of replacement / rearrangement.

Another goal is to create a self-supporting suspension device in which both sides can be used for hanging shelves, wire baskets, etc., which are easily accessible.

These goals are achieved by means of a self-supporting suspension device in accordance with the foregoing, which is characterized in that each rack contains at least two mutually parallel shelves that are connected to each other using at least one partition, while the internal distance between the shelves corresponds to the thickness of the support, and the support contains a slot at one of its ends, into which the rack partition is inserted, while the shelves surround the support by means of a clamp.

Methods for assembling a self-supporting suspension device in accordance with this invention are described in independent claims 1 and 12.

Other options for a self-supporting suspension device are apparent from the features set forth in the dependent claims.

With reference to FIGS. 1-16, which respectively depict elements in an embodiment of a self-supporting suspension device in accordance with the invention and an assembled device, the suspension device comprises at least two posts 1 and the same number of supports 2.

In this embodiment, the uprights 1 are a hollow guide or a profile with a rectangular cross-section, containing two mutually parallel shelves 3 and two mutually parallel partitions 4, see Fig.3. In this embodiment, the partitions 4 comprise slots or grooves 5 which are arranged in pairs and to which shelves, baskets, clothes shelves or similar devices can be suspended, either directly or by means of brackets, see, for example, Elfa Planerings-och Produktguide brochure " The racks 1 can also be made in the form of a U-shaped profile and, for example, are similar to the supporting guide in the aforementioned Elfa brochure, as shown in Fig. 19. However, the racks 1 must contain at least one partition 4 and a pair of parallel shelves 3, the purpose of which will become clear in the future.

The supports 2 are made in the form of an elongated element, preferably in the form of a hollow sheet metal element with an adjusting screw 6 at each end to ensure accurate vertical alignment of the corresponding rack, as will be apparent from reading the narrative. You can also use only one adjusting screw, see Fig. 19, or a support of any design suitable for this purpose. The support 2 has a sufficient thickness T in the transverse direction, see Fig. 19. In addition, at one of its ends, the support comprises a slot 7, which is oriented perpendicular to the longitudinal axis of the support and extends from the upper side of the support towards its lower side, but not to the very end. The distance A between the slot 7 and this end preferably corresponds to essentially half of the internal distance between the partitions 4 of the rack 1, for reasons that will be apparent from the description with reference to Fig. 18. In addition, the internal distance between the shelves 3 essentially corresponds to the thickness T of the support 2. Because the rack 1, when it is mounted on the support 2, must firmly and reliably grasp the support, so that they together function as a rigid assembly, which will be described more in detail in connection with the description of the assembly method.

The self-supporting suspension device in accordance with the invention also contains a stabilization element 8 so that the assembled suspension device has torsional rigidity in the longitudinal direction (in a plane located at right angles to the supports of the assembled suspension device), as shown by the two-way arrow L in Fig. 16 and as you know from the sets of shelves for storage mentioned in the introduction. Various types of stabilization elements are shown in FIGS. 8, 21-23, 25-29 and will be discussed in more detail in the description with reference to these drawings.

Finally, the self-supporting device in accordance with the invention in some embodiments also comprises a locking bar 9, see FIGS. 9, 18 and 24, the function of which will also be described with reference to these drawings.

Below, reference will be made to FIGS. 1 and 5-11, which illustrate various assembly steps of a section of an embodiment of a self-supporting suspension device in accordance with the invention. First, two racks 1 are inserted into the slot 7 in their respective supports 2, so that the lowermost end of the partition 4 abuts against the lowest part of the slot, and the shelves 3 are pressed into the end of the support at a distance A, see Figs. 1 and 5.

Then, the said parts are placed in the form of a single unit on the base, preferably on the floor, while the supports 2 are directed from each other. In this embodiment, the shelves 3 of the racks 1, in their lower part (in the vertical position of the suspension device) contain a pair of spaced through holes 11 in which the stabilization element 8 is fixed. In this embodiment, the stabilization element 8 is made in the form of two rods 12, which at their two ends contain a portion 13 of the rod, which bends essentially at right angles to the longitudinal axis of the rod, see FIG. 2. At a distance from this portion 13, an eyelet 14 is formed on the rod, and this distance substantially corresponds to the thickness of the shelves 3.

The first bent portion 13 of one of the rods 12 is inserted into the lower hole 11 of the rack 1, and the second bent portion 13 of the rod 12 is inserted into the upper hole 11 of the second rack and vice versa, so that the rods 12 are crossed with each other, as illustrated in Fig. 8.

In the next step, the supports 2 are rotated towards each other so as to become substantially parallel (and perpendicular to the floor), see FIG. 9. Then the bent section 13 and the eye 14 of the rods 12 fix the rods on the shelves 3 in such a way as to guarantee the mutual distance between the racks 1, as well as their parallelism, see figure 3.

In order for the supports 2 to remain parallel and for the assembled section to be a strong and stable assembly (to prevent the racks from turning), the locking bar 9 is mounted on the upper end of the racks, that is, at their end opposite the end inserted into the support 2, see FIG. 10. In this embodiment, the locking bar 9 is preferably an elongated profile that comprises two shelves 15 and at least one partition 16, see FIG. 4. At the ends of the locking bar 9 there is a slot 17, the width of which corresponds to the thickness of the shelf 3 racks. Thus, the locking bar is pushed into the upper ends of the two uprights 1, while the opposite shelves 3 of the uprights are inserted into the slots 17, which are most clearly shown in FIGS. 11 and 18.

Finally, the assembled section 18 is mounted and aligned by means of adjusting screws 6 so that the racks, if required, have an exact vertical orientation, see Fig. 11.

If it is necessary to add sections to the said self-supporting suspension device, the bent sections 13 of two rods 12 are inserted into two holes 11 of one of the racks, which are located opposite the said holes 11, see Figs. 12 and 13. If the preassembled section 18, see Fig. 11 , is located near the wall, the bent parts of the rods are inserted into the corresponding holes 11 with the rods 12 oriented in parallel and directed in the same direction as the support 2 of the rack in question, in contrast to the situation when eh first section 18, in which the direction of orientation of the rods opposite the direction of orientation of the support, see FIG. 6.

Then, the crossed rods are rotated so as to be located essentially in the same plane as the pre-assembled rods.

The rack 1, mounted on the support 2 in accordance with the above, is placed near the already assembled section 18, while its support is directed in the same direction, and the bent parts at the free ends of the two crossed rods are inserted into the corresponding aforementioned holes in the rack shelf 3, see Fig. 15. Then the support together with the stand rotates from the already assembled section 18 so as to become parallel and directed in the same direction as the other supports. And finally, the stand is secured by means of a locking bar 9, as described with reference to FIGS. 4 and 9-10.

If it is necessary to introduce additional sections into the suspension device, the above procedure is repeated.

In the above embodiment, a self-supporting suspension device in accordance with the invention, each rack contains only one support. If the suspension device is designed to be placed at a distance from the wall, for example as a room partition or for the safe use of both sides of the suspension device, it is preferable to use two supports for each rack. In this case, a profile with a closed section is used, that is, two shelves 3 and two partitions 4, see figure 3. As already mentioned with reference to figure 1, the distance And between the slot 7 of the support and its end closest to the slot, essentially corresponds to half the internal distance between the partitions 4 of the rack. Two supports 2 are placed with the ends mentioned adjacent to each other and directed in opposite directions. The rack 1 is inserted into the slots 7 and presses the ends of the supports against each other, as illustrated in Figs. 17 and 18, as a result of which a rigid and durable assembly is formed connecting the racks with the supports. If for each rack two supports are used instead of one support, the assembly method corresponds to that described above with reference to FIGS. 5-16.

In the aforementioned embodiments of the suspension device in accordance with the invention, a stabilization element 8 is provided in the form of two separate crossing rods which are fixed in adjacent racks. They can also be made in the form of a single node, i.e. before fixing to the posts 1, the rods 12 can be connected to each other. Thus, Fig. 27 depicts the rods 12 connected rotatably to each other by means of a through anchor bolt or a rivet connection 31 in the respective central parts of the rods. In an alternative embodiment, it is possible to bend each rod substantially into a V-shape and connect the rods 12 to each other using one or two bolts or rivet joints 31, as illustrated in FIG. FIG. 26 illustrates an embodiment in which the rods 12 bent into a V-shape are connected to each other to provide torsional rigidity by means of a connecting plate 32 to which they are attached, for example by welding or soldering.

The stabilization element 8 may also have other embodiments, one of which is illustrated in FIG. The stabilization element 8 may have an embodiment similar to the embodiment of the fixing beam 9, that is, a profile comprising two shelves 19 (of which only one is shown in FIG. 21) and at least one partition 21. A pair protrudes from its two ends. spaced closed or open clamps 22 (only closed clamps are shown in the drawing) that have a contour corresponding to the cross-section of the uprights, which in FIG. 21 is rectangular. Due to the torsional rigidity of this stabilization element, to ensure the necessary stability of the suspension device, it is sufficient to install the clamps 22 on each rack 1, that is, there is no need for a fixing bar. Instead of the clamps 22 in the partition / partitions 21 near the ends of the stabilization element 8, a through hole may be provided having a contour corresponding to the cross section of the struts into which the struts (not shown) are inserted.

When using the aforementioned stabilization element 8, the assembly of the suspension device includes fewer steps. After inserting one end of the struts into the slot of the respective supports (see FIG. 5), the drains are placed on the aforementioned base in such a way that the supports are located essentially at right angles to each other. Then the racks are passed into the clamps 22 or through holes, after which the already assembled suspension device is installed in a vertical position.

FIG. 22 illustrates another embodiment of a stabilization element 8. In this embodiment, the stabilization element comprises a relatively wide sheet metal plate 23, which at each end comprises a portion 24 bent into a U-shape. The shape of this section corresponds to the shape of the rack and partially surrounds the corresponding racks. The bent portion also includes inwardly directed hook elements 25 for fixing engagement with slots or grooves 5 of the uprights.

Fig. 23 illustrates an alternative embodiment of the stabilization element shown in Fig. 22. This embodiment of the stabilization element 8 differs from the stabilization element shown in FIG. 22 in that the sheet metal plate 23 contains at its ends not a U-shaped portion, but a portion 26 that bends at right angles to the sheet metal and which ends with hook-shaped elements 25 for engagement with slots or grooves 5 in the uprights 1.

The assembly of the suspension device using the stabilization element 8 corresponding to FIGS. 22 and 23 is preferably performed similarly to the assembly described with reference to FIG. 21, which is obvious to a person skilled in the art.

FIGS. 28 and 29 illustrate alternative embodiments of the stabilization element 8 shown in FIGS. 22 and 23. For greater clarity of the stabilization element being attached to the struts, the left struts shown in FIGS. 28 and 29 are shown in longitudinal section through two partitions 4 of the struts 1 In these embodiments, the stabilization element 8 comprises a flat (Fig. 28) or curved (Fig. 29) plate 23 made of sheet metal or other suitable material. Instead of fixing in the slots or grooves 5 of the uprights 1, holes 11 are used, shown in FIGS. 5-18. From each end of the plate 23, a pair of spaced hook elements 25 (illustrated in detail in FIG. 28) or a bent portion 13 (as shown in FIG. 29) protrudes. At the ends of the pair of rods 33 with a rectangular or circular cross-section, hook-shaped elements 25 and bent portions 13 of the rods are preferably placed respectively, which are fixed on the upper and lower parts of the plate 23 (in its attached state). The two end sections 34 of the plate function as the ears 14, illustrated in FIG.

The stabilization elements 8 corresponding to FIGS. 25-29 are assembled in the same way as described with reference to FIGS. 6-16 and 18, and in particular, FIGS. 8-9 and 14-16, which is obvious to a person skilled in this technical field.

24 is a cross-sectional view of an alternative embodiment of the locking bar 9. Here, the locking bar is arched, but of course it may have a different shape and, for example, may be linear with the angled end portions 28. In this embodiment, the ends of the locking bar the rails 9 contain protruding ridges or cut parts 27, the thickness of which essentially corresponds to half the internal distance between the shelves 3 racks, and the width of which essentially corresponds to oyaniyu partitions 4 between racks. Due to this, the two ridges 27 of the two locking bars 9 can be inserted in shape to the upper end of the same drain and prevent rotation of this rack.

A number of embodiments of a suspension device in accordance with the invention have been discussed above, and it will be apparent to those skilled in the art that the various features presented in the various drawings can be combined in various ways within the scope of the present invention.

Thus, the invention is not limited to the above description and illustrations in the drawings and can be modified within the scope of the attached claims.
