Description

background

The present invention relates to a holding element for an extendable cabinet frame for a pull-out tall cabinet.

State of the art

Tall cabinets are available in different heights to suit different room heights. Tall cabinets usually contain a number of shelves. These shelves can be connected to the cabinet walls using connecting elements. Such connecting elements are described, for example, in the document WO2017/015402 A1 described.

If these tall cabinets are extendable, the front of the tall cabinet is movable relative to the stationary side walls and the rear wall. In this case, the previously known connecting means cannot be used, since these connecting means are usually fixed to the side walls of the tall cabinet. If the extendable tall cabinet contains a plurality of shelves, these shelves are usually held in a cabinet frame, whereby the cabinet frame can be extended together with the shelves. The cabinet frame also serves as a holder for the front of the tall cabinet.

Such a cabinet frame usually consists of two vertically running support elements and at least two horizontal support elements connecting the two vertically running support elements, which form a support element frame. The horizontal support elements are slidably mounted in the base plate and the cover plate. For this purpose, a guide rail can be attached to the base plate and to the underside of the cover plate, which accommodates the associated guide elements of the horizontal support elements. In order to accommodate different construction heights, such cabinet frames have a telescopic design. In particular, the two vertically running support elements contain at least one outer support element and one inner support element, whereby the inner support element can be slid in the outer support element. The inner support element can be moved, for example, by means of Screws can be attached to any position in the outer support element so that the overall height of the vertical support element can be adjusted to the desired height of the tall cabinet. This makes it possible to easily adapt a standard cabinet frame, hereinafter referred to as the cabinet base frame, to different heights.

The additional height may not be used if no additional storage space can be provided on the inner support element. To remedy this disadvantage, an additional holding device is usually provided, which can be used to hold additional storage spaces. According to the previously known solution, holding hooks are provided at predetermined intervals on the outside of the outer support element, into which a corresponding support surface can be hung at the desired height. Such holding hooks cannot be attached directly to the inner support element, since the holding hooks would make it impossible to move the inner support element in the outer support element. For this purpose, a support element sleeve is provided as a holding element, which is arranged so that it can be moved on the inner support element. This support element sleeve can be attached to any position on the inner support element using locking screws. The support element sleeve is equipped with holding hooks for an additional storage space, so that one (or more) additional storage spaces can be attached to the support element sleeve. This makes it possible to use the additional height of a tall cabinet.

The support element sleeve must be provided before the cabinet frame is installed in the tall cabinet. Since the cabinet frame has to support the shelves and the front, it is permanently connected to the base plate and the cover plate via a guide element. Retrofitting an existing cabinet frame with the corresponding support element sleeves therefore requires the entire frame to be removed, which is very time-consuming.

In addition, the support element sleeve must be precisely leveled to avoid a storage surface deviating from the desired horizontal position.

Another disadvantage is that the distance to existing storage areas can vary. The storage space under and/or above the additional storage area can be larger or smaller than the Distance between the remaining shelves. Therefore, the available storage space may not be used optimally, especially if the distance to the adjacent shelf is smaller.

A holding device for shelves for a shelf, which can be attached to different places on a support element, is also available in the DE 3517568 A1 shown. The holding device comprises a sleeve, a locking device and a base insert which is connected to the corresponding shelf of the rack. The base device is put over the holding device, whereby the holding device can be fixed on the support element at the desired height. Since the sleeve has a closed, square cross-section, it must be put over the end of the support element. If the end of the support element is at too great a height or a closed frame is formed by the support elements, the attachment of such a sleeve involves some effort and, like the support element sleeve described above, can only be carried out before the support element frame is assembled.

A connecting element for a shelf for storing plants is shown in the document US2022/0218108 A1 disclosed. The connecting element comprises a first wall element, a second wall element and a third wall element, wherein the second wall element and the third wall element are arranged adjacent to the first wall element. The second wall element is arranged opposite the third wall element. A fourth wall element is arranged opposite the first wall element. The fourth wall element has a slot running in the longitudinal direction. To increase the structural stability of the vertical supports of the shelf, the connecting element is inserted into the support, which encloses the connecting element on all sides. The connecting element is thus arranged inside the support with a C-shaped cross-section. Fastening elements, for example rivets, are attached to the inside of the connecting element and are received in corresponding openings in the connecting element and corresponding openings in the support.

With the document US2022/0218108 A1 Using the connector described above, two supports can be connected to each other to increase the distance between adjacent shelves of the shelf if necessary, when the plants require a greater height due to their growth. This solution allows the height of the vertical supports of the shelf to be be increased. The solution relates to a connecting element for increasing the distance between two adjacent shelves of a shelf whose overall height can be changed. This solution is not suitable for a holding element for a cabinet frame for a tall cabinet with a plurality of shelves, wherein the holding element is designed in such a way that additional shelves can be attached, because the overall height of the cabinet and thus also the overall height of the support element frame, which is intended to accommodate the shelves, is predetermined.

There is therefore a need for a holding element which can be attached to a support element frame for attaching storage surfaces for a tall cupboard without any significant effort and without the use of tools.

The object of the invention is to provide a holding element for a cabinet frame which can be easily attached to the support element frame in order to provide an additional storage area. In addition, there is a need for a holding element by means of which the distance between the lowest additional storage area and the topmost storage area of the cabinet base frame can be set to a certain, predetermined distance.

Description of the invention

The object of the invention is achieved by a holding element for an extendable cabinet frame for a pull-out tall cabinet according to claim 1. Advantageous embodiments of the holding element for the extendable cabinet frame are the subject of claims 2 to 9. An extendable cabinet frame containing a holding element according to the invention is the subject of claim 10.

When the term "for example" is used in the following description, this term refers to embodiments and/or embodiments, which is not necessarily to be understood as a more preferred application of the teaching of the invention. Similarly, the terms "preferably", "preferred" are to be understood as referring to an example from a set of embodiments and/or embodiments, which is not necessarily to be understood as a more preferred application of the teaching of the invention. Accordingly, the terms "for example", "preferably" or "preferably" refer to a plurality of embodiments and/or embodiments.

The following detailed description contains various embodiments of the holding element according to the invention. The description of a specific holding element is to be regarded as an example only. In the description and the claims, the terms "include", "comprise", "have" are interpreted as "include, but not limited to".

A holding element for an extendable cabinet frame for a pull-out tall cabinet contains a first wall element, a second wall element and a third wall element, wherein the second wall element and the third wall element are arranged adjacent to the first wall element. The second wall element is arranged opposite the third wall element. A fourth wall element is arranged opposite the first wall element. The first, second, third and fourth wall elements enclose a cuboid-shaped cavity. In the installed state, the support element unit of the cabinet frame is located in this cuboid-shaped cavity.

The fourth wall element has a slot running in the longitudinal direction. The first, second, third and fourth wall elements are designed to enclose the support element unit of the cabinet frame. The first, second, third and fourth wall elements are designed to rest on the support element unit of the cabinet frame. In other words, the first, second, third and fourth wall elements enclose the support element unit of the cabinet frame in the installed state. In particular, the inner surfaces of the first, second, third and fourth wall elements rest on the corresponding outer surfaces of the support element unit of the cabinet frame.

The second wall element and the third wall element each have an outer side, wherein at least one receiving element for an additional storage surface is attached to at least one of the outer sides.

The holding element thus has a substantially C-shaped cross-section, wherein the base of the C-shaped cross-section is formed by the first wall element, wherein the legs of the C-shaped cross-section adjoining the base are formed by the second and third wall elements, and wherein end sections of the C-shaped cross-section adjoining the legs are formed by the fourth wall element, which contains the slot. In particular, the holding element is elastically deformable in such a way that that the slot can be widened manually using minimal force. The retaining element can thus be attached to the support element unit of the extendable cabinet frame without the need for tools.

According to one embodiment, the second wall element and the third wall element each have an outer side, with at least one hook element or a recess being attached to at least one of the outer sides. If one or more receiving elements are provided, an additional storage area can be provided if the tall cabinet has a higher construction height than the minimum construction height.

According to one embodiment, the slot has a width that is variable in at least one partial area. In particular, the holding element has a first end and a second end, wherein the partial area in which the width of the slot is variable adjoins at least one of the first or second ends. According to this embodiment, the holding element can be plugged onto a support element of the cabinet frame particularly easily with even less effort. In particular, the partial area can have a length that is a maximum of 35% of a total length L of the holding element. In particular, the holding element can be plugged onto the support element at an acute angle in relation to the support element with the partial area with variable slot width. The slot is already partially widened by the support element, so that only a small amount of additional effort is required to plug the entire holding element onto the support element.

In particular, the width of the slot in the partial area decreases with increasing distance from the first or second end adjoining the partial area. According to this embodiment, the holding element is thus less rigid at the first or second end adjoining the partial area, so that elastic deformation in the partial area is facilitated. The holding element can thus be attached to a carrier element with less effort. According to an alternative embodiment, such a partial area can also be provided at the first and second ends.

According to one embodiment, the receiving element closest to the first end has a distance from the first end which is designed such that in the installed state a standard distance is obtained from each adjacent receiving element. In many cases, storage areas are installed at a constant distance from each other so that the storage space created above each of the storage areas is sufficient for each Storage area has the same height. When the holding element is used, it is designed in such a way that its underside rests on the outer support element of the cabinet frame. The holding element is plugged onto the inner support element of the cabinet frame. Therefore, the receiving element closest to the first end can be provided at a corresponding distance from the first end so that the standard distance is achieved when installed. This means that additional storage areas that are provided to utilize the additional height of the tall cabinet can also be arranged exactly at the standard distance. On the one hand, the same storage space is available for each storage area, and on the other hand, the arrangement of adjacent storage areas at the same distance from one another can be desirable for aesthetic reasons.

According to one embodiment, the holding element is elastically deformable in such a way that it is designed for tool-free assembly on a support element unit belonging to a cabinet frame. The elasticity of the holding element enables it to be assembled without tools on the associated support element unit of the cabinet frame. In particular, the holding element can contain a plastic or a metal. For example, the holding element can be made of plastic, which simplifies its manufacture, since such a holding element can be manufactured using an injection molding process, for example. For example, the holding element can be made of a metal, which allows an extended service life of the holding element to be achieved.

The invention further relates to an extendable cabinet frame comprising a holding element according to one of the preceding embodiments. In particular, the invention relates to an extendable cabinet frame for a pull-out tall cabinet comprising a support element frame and at least a first and a second holding element. The support element frame contains a first support element unit, a second support element unit, a lower guide element and an upper guide element. The first support element unit and the second support element unit contain a plurality of receiving elements for at least one storage surface. The first support element unit and the second support element unit have a height that can be adjusted depending on the height of the tall cabinet.

Each of the first and second support members includes a first wall member, a second wall member and a third wall member. The second wall member and the third Wall elements are arranged adjacent to the first wall element, with the second wall element being arranged opposite the third wall element. A fourth wall element is arranged opposite the first wall element, so that the first, second, third and fourth wall elements enclose a cuboid-shaped cavity. The fourth wall element has a slot running in the longitudinal direction.

The holding element is designed such that the first, second, third and fourth wall elements enclose the corresponding first or second carrier element unit. The second wall element and the third wall element each have an outer side, with at least one receiving element for an additional storage surface being attached to at least one of the outer sides. The holding element can contain any of the features described above.

According to one embodiment, the first carrier element unit contains a first partial carrier element and a second partial carrier element. The second carrier element unit contains a first partial carrier element and a second partial carrier element. According to this embodiment, the second partial carrier elements can be moved telescopically in the first partial carrier elements. According to one embodiment, the first and second carrier element units run in a substantially vertical direction. In particular, the first and second carrier element units are arranged in a vertical direction in the installed state.

According to one embodiment, at least one of the first or second guide elements comprises at least one stationary guide rail and a guide rail that is movable relative to the stationary guide rail via rolling elements. The stationary guide rail can be fastened in particular to the cabinet floor or to the cabinet ceiling. The movable guide rail is movable relative to the stationary guide rail. In particular, the first and second guide elements can contain roller tracks for rolling elements. The movement of the rolling elements on the roller tracks enables the movable guide rail to be moved relative to the stationary guide rail.

The second wall element 3 and the third wall element 3 are arranged adjacent to the first wall element 1. The second wall element 2 is arranged opposite the third wall element 3. A fourth wall element 4 is arranged opposite the first wall element. The first, second, third and fourth wall elements 1, 2, 3, 4 enclose a cuboid-shaped cavity. The fourth wall element has a slot 5 running in the longitudinal direction. The second wall element and the third wall element each have an outer side, wherein at least on one of the outer sides at least one receiving element 6 for a storage area is attached. This storage area is an additional storage area that can be used in addition to existing storage areas. The first, second, third and fourth wall elements are designed to rest on a support element unit of the cabinet frame. The support element unit can be part of a support element frame of a cabinet frame 15, as in Fig. 5a or Fig. 5b The support element frame serves to accommodate a plurality of storage surfaces, which are known per se and have therefore been omitted from the simplified illustration. According to the present embodiment, two receiving elements 6 are attached to the outside of the second wall element 2 and two receiving elements 6 are attached to the outside of the third wall element 3.

Fig.2 shows a top view of the holding element 10 according to Fig.1 . Any rounding of the edges has been omitted in the simplified drawing. The holding element 1 comprises the first wall element 2, the second wall element 2, which adjoins the first wall element 1, and the third wall element 3, which adjoins the first wall element 1 on the opposite side. The second wall element 2 and the third wall element 3 extend at an angle of essentially 90 degrees to the first wall element 1. The fourth wall element 4 also adjoins the second wall element 2. The fourth wall element 4 adjoins the third wall element 3 in the same way. The second wall element 2 is arranged in particular parallel to the third wall element 3. The fourth wall element 4 is arranged in particular parallel to the first wall element 1. The fourth wall element 4 contains a slot 5 which runs in the longitudinal direction of the holding element. The longitudinal direction of the holding element extends at a right angle to the plane of the drawing. A first and a second partial wall element of the fourth wall element 4 are formed by the slot 5. The holding element 10 thus has a substantially C-shaped cross-section, the base of the C-shaped cross-section being formed by the first wall element 1, the legs of the C-shaped cross-section adjoining the base being formed by the second and third wall elements 2, 3. The two legs and thus the second and third wall elements 2, 3 are arranged opposite one another. The fourth wall element is formed by end sections of the C-shaped cross-section adjoining the legs.
