EP4176768B1 - Shelf system comprised of injection moulded plastic parts - Google Patents

Description

The invention relates to a shelving system made of injection-molded plastic parts, in which a number of frame elements can be plugged together to form a shelving frame with one or more shelf levels for accommodating shelves and / or drawers, according to the preamble of claim 1.

The assembled shelf frame of such a shelf system therefore comprises, depending on the shelf level, at least one circumferential, horizontal frame in its basic shape, i.e. square in plan view, and a vertical support at each corner of the frame. The vertical supports extend from the frame of a first shelf level or, if each shelf level comprises more than one frame, from one of the frames of the first shelf level to the or a frame of an adjacent second shelf level. For reasons of stability, the vertical supports are designed in one piece in order to form the individual shelf levels and the shelf frame as a whole together with the respective horizontal frame.

Shelves made of plastic, in particular composed of injection-molded plastic parts, which are optionally equipped with drawers or containers placed in the shelf levels, can be used in a variety of ways because they are not only comparatively light, but due to the material properties of plastic they are suitable for environmental conditions for which wood-based materials are suitable and metals are not suitable, for example in damp rooms. In addition, the design options when producing the shelf using plastic injection molding are particularly diverse.

In order to bring a shelf from the place of manufacture to the point of sale and/or to the end customer, it is advantageous not to close the shelf in the assembled state transport, as the transport volume would be many times larger than when transporting a kit. This applies in particular to shelves made of plastic, as the ratio of weight to volume is particularly unfavorable when the shelf is transported in the assembled state. Therefore, it is common to manufacture plastic shelves as a shelving system of the present type, in which a number of rack elements are fitted together to form a shelf frame and to transport the shelving system in the unassembled state.

However, if the shelf consists essentially of frame elements fitted together, the stability of the shelf frame is a critical issue that requires special attention. It is therefore common practice to produce a circumferential horizontal frame, which is square in its basic shape, in one piece for each shelf level in order to achieve the greatest possible stability of the assembled shelf frame. The vertical supports are then inserted into the corners of the horizontal frame, and a relatively large amount of effort must be invested at this point in order to make the plug-in connection stable. This is usually achieved using reinforcing ribs, material doubling and the like. Nevertheless, the stability of a shelf frame composed of frame elements in this way, especially if it comprises several shelf levels, is often in need of improvement.

The present invention is therefore based on the object of improving a shelving system of the type mentioned in terms of its stability without having to accept disadvantages for the transport of the shelving system.

This task is solved by a shelving system with the features of claim 1. Preferred refinements and developments of the shelving system according to the invention are set out in claims 2 to 15.

A shelf system designed according to the invention made of injection-molded plastic parts, in which a number of frame elements can be plugged together, in order to form a shelf frame with one or more shelf levels for accommodating shelves, containers and / or drawers, the assembled shelf frame having at least one circumferential, square, in particular rectangular horizontal frame for each shelf level and a vertical support at each corner of the frame , which extends from the or a frame of a first shelf level to the or a frame of an adjacent second shelf level, differs from the prior art significantly in that the frame elements, insofar as they form or include a support, each consist of one support and two first and second frame elements which are integrally formed thereon and which can be plugged together with further frame elements to form the frame, the first and second frame elements enclosing a corner angle of the frame between them.

The frame elements designed according to the invention thus extend in all three spatial directions: the support runs vertically in its installed position, while the two frame elements extend horizontally in the installed position, each forming part of the frame and thereby enclosing the corner angle of the frame between them. The three legs of the frame elements according to the invention, i.e. the support and the first and second frame elements, thus run in three different spatial directions. If the square horizontal frame of the shelving system is rectangular, the three legs of the frame elements run in mutually orthogonal directions.

Since the frame elements according to the invention are injection molded in one piece, the three legs mentioned are extremely stable and connected to one another without play, and since they extend in three different spatial directions, these frame elements give the assembled shelf frame a particularly high level of stability. Nevertheless, they can be transported to save space when not assembled in the initial state.

The frame elements of the shelving system according to the invention can be designed differently; In addition to the frame elements essential to the invention with three legs, i.e. a support and two frame elements integrally formed thereon, further frame elements can be provided, in particular in order to complete the frame with frame elements without molded supports. For example, it can also be provided to provide additional, one-piece frames, so that each shelf level is provided with two frames, one one-piece frame and one assembled frame.

However, it is particularly preferred if a shelf level is formed by only four frame elements, each of which includes a support and two frame elements, the frame elements being able to be plugged together with the frame elements of the two adjacent frame elements and the frame elements of all four frame elements together forming the frame of this level Form a shelf frame. Such a design of the shelving system according to the invention avoids unnecessary complexities when putting the frame elements together, and as little material as possible is used, which is advantageous from a cost and sustainability perspective. Consequently, in this preferred embodiment of the shelving system according to the invention, the supports are also designed in one piece, which is optimal in terms of stability criteria.

In order to solve the conflict of objectives of using as little material as possible while at the same time having the highest possible stability, it is preferred if the frame elements and possibly also the supports are shaped as a hollow profile or as an open profile, in the case of the frame elements preferably as a profile that is open at the bottom. As is known, the profiling increases the stability of the components while at the same time advantageously reducing the wall thickness.

In order to improve the stability of the plug connections, i.e. the connection of the frame elements to one another to form the frame, it is preferred in the present invention if each first frame element of each frame element, insofar as this forms or comprises a support, an immersion piece with a reduced profile cross-section is formed, and at the same time every second frame element with a counterpart (if the second frame element is shaped as a downwardly open profile) and / or open end (if the second Frame element is shaped as a hollow profile) is provided to accommodate the immersion piece. In this way, the first and second frame elements can be plugged together and a very stable plug connection can be achieved.

It is further preferred here if the immersion piece of the first frame element is provided with at least one locking lug, and an end region of the second frame element or the counterpart of the second frame element is provided with a recess adapted to this locking lug, or vice versa, i.e. that the counterpart or the end region the second frame element is provided with the locking lug and the first frame element is provided with the adapted recess. This also results in a positive connection in the insertion direction, so that the frame elements are secured to one another in a form-fitting manner in all three spatial directions after they have been plugged together. On the one hand, this increases stability; On the other hand, depending on the design of the locking lugs, this results in a plug connection that can no longer be removed without being destroyed. This is a great advantage, especially when it comes to full shelves, where the parts must under no circumstances come loose from one another unintentionally.

To the extent that the frame elements of the shelving system according to the invention are shaped as a hollow profile or as a profile that is open at the bottom, it is preferred if the profile shape of the frame has a gradation running around the inside of the frame to accommodate a shelf, a container or a drawer. Due to such a circumferential gradation, the container or drawer snaps into the shelf due to gravity, and a shelf can be stably fitted into the gradation. The advantages are apparent.

In order to further optimize the stability of the shelving system according to the invention, the supports of the frame elements can comprise a head element at their end opposite the frame elements, which is preferably integrally formed onto the support or the entire frame element. As a counterpart, receptacles for the head elements are provided in the frame or in the corner area of the two frame elements of the frame element. The supports of a first shelf level can thus be inserted with their head elements into suitable receptacles in a second, adjacent shelf level.

This connection can also be additionally stabilized with at least one locking lug in the head element or in the matching receptacle in the frame and with at least one recess in the frame or in the head element adapted to the locking lug. As with the frame elements, a positive connection can be established between the support of a first shelf level and the frame of an adjacent second shelf level using such a locking lug or through several such locking lugs, even in the plugging direction. This can also optionally achieve a connection that can no longer be detached in a non-destructive manner.

The frame elements of the shelving system according to the invention can be plugged together in such a way that the supports extend downwards from the frame elements and are therefore plugged from above onto the frame elements of a shelf level below. In the context of the present invention, however, it is preferred to be the other way around, in particular if the supports are provided with head elements for insertion into suitable receptacles in the frame of a second adjacent shelf level, i.e. that the receptacles of the frame are provided on the underside of the frame, while the supports are separated from the frame extend upwards.

In this case, adapter pieces can advantageously be provided which are inserted into the receptacles of the lowest frame of the shelf frame in order to attach feet or rollers to the underside of the frame. Alternatively or In addition, four bearing points for storing one roll each can be formed on the underside of the frame. A design with rollers makes it possible to easily move the entire shelf frame even when items are stored on the shelf. The particularly light and stable nature of a shelf made of injection-molded plastic parts enables this design, which offers advantages particularly when used in the household, for example in the bathroom.

If the shelf levels are formed by a frame underneath and four supports pointing upwards, a cover is expediently provided for fitting onto the four supports of a shelf level in order to complete the top shelf level. To the extent that the supports are provided with head elements for insertion into suitable receptacles in the context of a second adjacent shelf level, it is expedient if the lid is equipped with such suitable receptacles for the head elements of the supports. In this way, it can then be placed particularly stably on the supports of the top shelf level and connected to them.

The shelving system according to the invention offers particular advantages if at least one drawer or container is provided for insertion into a shelf level; because then it is possible, and also preferred in the context of the present invention, for the frame elements to be placed in the drawer or container as long as they are not plugged together. In this case, the dimensions of the frame elements with support and two first and second frame elements integrally formed thereon must be dimensioned in such a way that the frame elements can be placed in the drawer or container.

This is particularly important when the first frame elements of the frame elements are provided with immersion pieces for plugging together; because these immersion pieces should be as long as possible for optimal stability of the assembled frame. At the same time, however, it is preferred if they are only long enough for the corresponding frame element can still be placed in the drawer or container. It is therefore expedient if the first frame elements of the frame elements are provided with immersion pieces that just allow the frame elements to be inserted into the drawer or container.

The shelving system according to the invention is therefore particularly preferably designed in such a way that it consists of several shelf levels, at least one drawer or at least one container and a lid, and that a shelf level is constructed for transport and the drawer or container is inserted into it, while the remaining frame elements inserted into the drawer or container in a non-assembled state and the lid is placed on it or placed on the supports of the assembled shelf level.

If several drawers and/or containers are provided, these can be placed in the built-up lowest shelf level when immersed in one another and the remaining frame elements can be placed in the top drawer or the top container. This results in a particularly compact transport structure for the individual parts of the shelving system according to the invention, which is at the same time stable and therefore offers particular advantages during transport.

An exemplary embodiment of a shelf system designed according to the invention is described and explained in more detail below with reference to the accompanying drawings. The invention is not limited to this embodiment; Nevertheless, the following description and the drawings may reveal further features that may be essential to the invention.

Figure 1 shows an isometric representation of an exemplary embodiment of a shelving system designed according to the invention, as it can be used by the end customer in the assembled state. This shelving system has a Shelf frame 1 with three shelf levels 2, 2', 2", which is completed on the top side with a lid 3 and on the underside with four rollers 4 to form a shelving system. The shelf frame 1 is used to hold drawers or containers (not shown here); however, it can can also be completed with shelves (not shown).

The shelf frame 1 of the present shelving system is composed of a total of twelve frame elements 5, which form a circumferential frame 6 per shelf level 2, 2 ', 2", square in its basic shape, in this case rectangular, from which four supports 7 extend upwards to the frame 6 'the shelf level 2' above. The supports 7 are located in the corners of the frame 6 in order to keep the shelf accessible from all sides.

The frame 6 of each shelf level 2 has a profile shape with a gradation 8 running around the inside of the frame 6. With the help of this gradation 8, a shelf (not shown) can be inserted into the frame 6. Alternatively, a drawer or a container (not shown here) can snap into a rest position when pushed into the shelf frame 1 using the circumferential gradation 8 in the frame 6. This is particularly helpful if the shelf frame 1 is to be moved to another location using the rollers.

The frame elements 5 from which the shelf frame 1 in Figure 1 is assembled are in the Figures 2 and 3 presented in different perspectives. If the frame 6, which is formed by the frame elements 5, has a square shape, the frame elements 5 can be designed identically. In the present exemplary embodiment, the frame 6 is rectangular in shape with two longer and two shorter sides; accordingly there is a “right” and a “left” frame element 5.

Each frame element 5 is manufactured as a one-piece injection-molded part, and it each comprises a support 7 and two frame elements integrally formed thereon, namely a first frame element 9 and a second frame element 10. The supports 7 expand at their ends opposite the frame elements 9, 10 into a head element 11, with the help of which a positive plug-in connection can be produced with the frame 6 'of the shelf level 2' above. For this purpose, receptacles 12 are formed in the corner of the connecting area of the first 9 and second frame element 10 on the underside of the frame element 5 or the frame 6, into which the head elements 11 of adjacent frame elements 5 can be inserted appropriately ( Figure 3 ). In order to form a positive connection between the assembled parts in the direction of the insertion movement, locking lugs 13 are formed on two sides of the head elements 11, which lock into recesses 14 in the receptacles 12.

Out of Figure 7 , a sectional view of the connection between a support 7 and a frame 6 'of the shelf level above, is the positive plug-in connection that results from the fit of the head element 11 in the receptacle 12' and additionally due to the locking lug 13 snapping into the recess 14' , explained in detail.

From the Figures 2 and 3 It can also be seen that the first frame elements 9 continue at their ends into an immersion piece 15, which has a reduced profile cross section and can be inserted into the end of the second frame element 10 of a further frame element 5. The immersion pieces 15 are relatively long in relation to the length of the two frame elements 9, 10, which optimizes the stability of the frame 6 composed of the frame elements 9, 10.

Like in particular Figure 3 shows, the supports 7 are formed as a hollow profile and the frame elements 9, 10 as a downwardly open profile, the already mentioned receptacle 12 for a head element 11 of a further frame element 5 being additionally formed into the profile. To accommodate the immersion piece 15 when assembling the frame 6, the second frame element 10, designed as an open profile, is completed at its end to form a counterpart 16, which serves to accommodate the immersion piece 15 appropriately. The fit between the immersion piece 15 and the counterpart 16 as well as the profile shape of the frame elements 9, 10 ensure a highly stable, positive plug connection.

In order to also form a positive connection in the insertion direction, the immersion pieces 15 are each provided with a locking lug 17, which lock into a recess 18 adapted to this locking lug 17 in the counterpart 16 as soon as the first frame element 9 of a first frame element 5 is connected to the second frame element 10 of a second Frame element 5 is put together.

This form fit is shown in a sectional view Figure 4 shown in detail. The reference numbers used there are identical to the reference numbers in the previous figures, which were used for the same elements. In this respect, the Figure 4 reference is made to the description of the preceding figures.

Figure 5 shows a shelf level 2 of the shelf frame 1 Figure 1 . This shelf level 2 consists of a circumferential, rectangular frame 6 and four supports 7 attached to its corners, the supports 7 not being plugged onto a one-piece frame 6 as in the prior art, but the shelf level 2 consisting of four plugged-together three-dimensional frame elements 5 exists. The frame elements 5 have already been described in detail with reference to Figures 2 and 3. In this respect, reference can be made to the previous description.

What in the context of Figures 2, 3 and 5 becomes obvious, the inventive core idea is to divide the frame 6 into four corner pieces using two cutting planes, each consisting of a first frame element 9 and a second frame element 10, which enclose a corner angle of the frame 6, here a right angle between them. Integral with these corner pieces of the frame 6 during injection molding is the support 7 of the corresponding corner of the Frame 6 molded. This creates a frame element 5 from which the individual shelf levels 2 can be assembled using a plug connection. The frame elements 5 thus extend in one piece in three orthogonal spatial directions, so that ultimately there is no stable plane with unstable elements attached to it in the third spatial direction, as is the case in the prior art. Instead, the three spatial directions of the shelf frame 1 are stable in all three spatial directions due to the one-piece design of the frame elements 5 with their orthogonal legs.

The fact that in the present exemplary embodiment the frame 6 is not supplemented with intermediate pieces (not shown) between the first and second frame elements 9, 10, but rather the complete frame is assembled with the two frame elements 9, 10 of the four frame elements 5, increases stability the frame 6 and thus the entire shelf frame 1 additionally.

The Figure 6 shows two shelf levels 2, 2', as already shown in Figure 5 shown and each consisting of four frame elements 5 according to Figures 2 and 3 are assembled when placing the two shelf levels 2, 2` on top of each other. Here too, the same reference numerals are used for identical parts of the shelf levels 2, 2 'as in the previous figures, so that reference can be made to the description of the previous figures for explanation.

In Figure 8 is the top shelf level 2" of the shelf frame 1 in a slightly different perspective Figure 1 shown to illustrate the plug-in connection between the supports 7" of the frame elements 5" of the top shelf level 2" with the lid 3:
The lid 3 is also provided in its four corners with receptacles 12 which are molded into the lid 3 and into which the head elements 11" of the supports 7" of the top shelf level 2" can be inserted appropriately. Also recesses 14 for the locking lugs 13" of the head elements 11" are provided in the receptacles 12 of the lid 3, so that the lid 3 sits firmly on the top shelf level 2" and can no longer be removed from it.

Out of Figure 9 shows how the rollers 4 are attached to the frame 6 of the lowest shelf level 2. For this purpose, the shelf frame 1 has been turned over in the illustration so that you can see the underside. To attach the rollers 4 to the frame 6, four adapter pieces 19 are provided, which are placed in the receptacles 12, which actually serve for head elements 11 of further supports 7. These adapter pieces 19 are also equipped with locking lugs 13 in order to be inserted positively and firmly into the receptacles 12. On the underside, the adapter pieces 19 each have a cylindrical opening 20, into which a bearing pin 21 of a roller 4 can be inserted and stored therein.

Additionally, how Figure 9 Also clarified, a bearing point 25 is formed on the underside of each frame element 5. In the present case, this also forms a cylindrical opening into which a bearing pin 21 of a roller 4 can be inserted and stored therein. With these bearing points 25, rollers 4 can be attached to the frame 6 without having to use adapter pieces 19.

The Figures 10 , 11 and 12 Finally, show how advantageously the present exemplary embodiment of a shelf system designed according to the invention can be packaged for shipping:
The lowest shelf level 2, consisting of four assembled frame elements 5, which form the frame 6 and four supports 7 extending upwards, is already assembled. A container 22 is inserted into the frame 6 and, as intended, is set to fit into the circumferential gradation 8 of the frame 6. Two further containers 22' and 22" are placed in the container 22, immersed in it.

The container 22" for the top shelf level 2" ( Figure 1 ) accommodates the frame elements 5' and 5" of the other two shelf levels 2 in individual parts. For this purpose, their first and second frame elements 9, 10 are dimensioned so that they fit into the container 22". In addition, the container 22" also accommodates the rollers 4 and the adapter pieces 19.

Completed by the lid 3 ( Figure 11 ), all individual parts of the in Figure 1 The illustrated embodiment of a shelving system according to the invention is compact and stably transportable in a small space.

How Figure 12 shows, only two boxes 23 in the form of hollow cuboid halves need to be placed over two sides of the in Figure 11 The structure shown can be placed inside out and fixed with a strap 24 to form a stable package for shipping. It is obvious that these few steps that are possible using the present invention and are necessary for shipping a shelving system according to the invention keep the effort as low as possible and allow the shelving system to be transported in as space-saving a way as possible. At the same time, the fully assembled shelving system is very stable ( Figure 1 ) due to the frame elements 5 extending in three spatial directions, from which the shelf frame 1 of the shelf system is composed.
