DESCRIPTION

Door shelf for a refrigeration and / or freezing device

The present invention refers to a door shelf for a refrigeration and / or freezing apparatus with at least one retaining part movably arranged, to fix at least one object that is located on the door shelf.

A retention portion of that kind of a door shelf is used to prevent or limit as much as possible unwanted movements of products to be refrigerated, by closing and opening the door (centrifugal forces). Due to the state of the art, door shelves are already known with retention parts arranged in a movable manner. In the known door shelves, the retention part is fastened in a molding or in the plastic shelf itself. Such fastening has the disadvantage that a retention part undergoes a comparatively significant deformation. This in particular can be problematic because the hooks of the retaining part are shaped and made correspondingly thin, in order to generally guarantee deformation. In the case of improper handling, however, this can lead to breakage of the hook and, thus, to the uselessness of the retention part. This applies in particular when the material used is comparatively brittle, as is the case, for example, with polystyrene. During use and movement, the hooks are loaded again. With the passage of time this can eventually lead to a breakage of the hooks.

From DE 102 08 067 A1, a door shelf unit for a refrigeration apparatus according to the preamble of claim 1 is known, which comprises a door shelf with a positioning surface for housing objects and at least one side wall . The door shelf has a compartment separator that can be moved in the side wall. The side wall also has an open downward groove in which a spring of the movable compartment separator is engaged along the groove. By application CN 2 588 292 And a door shelf is also known where the inner side of an anterior wall has sliding grooves in which a sliding plate is arranged.

The object of the present invention, therefore, is to improve in this respect a door shelf of the kind mentioned in the introduction, so that the retention part is exposed only to comparatively reduced loads and, therefore, presents a particularly long lifespan.

This object will be achieved through a door shelf with the features of claim 1.

Accordingly, it is envisaged that the door shelf has at least one first guide element in which the retention part is disposed displaceably through at least a second guide element, where the guide elements are made so that the Second guide element, through a relative movement with respect to the first guide element, in the lateral direction of the door shelf, can be introduced into the first guide element and / or can be separated from the first guide element. The essential advantage of that embodiment of the invention lies in the fact that the retention part is introduced laterally, due to which the loads of the retention part are kept reduced, so that the disadvantages known by the State of the art, mentioned above.

It is possible that the first guide element disposed in the door shelf is realized so that the retention part can not only be introduced in one place, but in several places, for example on both sides of the door shelf.

The expression "that can be introduced" is understood so that the two guide elements can be engaged with one another in a suitable manner, so that the retention part is arranged in a relative displaceable manner with respect to the door shelf. The expression does not presuppose a special realization of the guiding elements.

In addition, the present invention refers to a preferred embodiment for a refrigeration and / or freezing apparatus with at least one retaining part movably arranged to fix at least one object that is on the door shelf, where the shelf The door has at least one first guide element in which the retention part is disposed displaceably through at least a second guide element, where the guide elements are arranged so that they are not visible in the case of a view from the door shelf from the front and / or from the top. Through this variant of the invention a particularly advantageous total optical impression of the arrangement of the retention part is achieved. In this way, it is envisaged that the fixing of the retention part is arranged in a hidden way. The expression "not visible" should also be understood in the case that the guide elements, in the case of a view of the door shelf from the front and / or from above, are only visible through the material of the door shelf, as well as of the retention or translucent part, so that they cannot be seen "geometrically".

In order to simplify an introduction of the second guide element of the retention part in the first guide element, according to the invention it is envisaged that the first guide element is made chamfered in its end area, that is, in the area in which the retention part is introduced or removed.

By means of an insert chamfering of that kind, the retention part can be mounted and removed easily.

In another variant of the invention it is provided that the door shelf has a limiting means, preferably a wall that forms a limitation of the door shelf, and that the first guide element is arranged in the mentioned limiting means or on the wall.

Preferably, the limiting means, from the view of a user, is located near the area or in the area of the front side of the door shelf. By way of example, the limiting means may be a bar, grid or wall of the door shelf arranged on the front side.

In another variant of the invention it is envisioned that the retention part is arranged in a suspended manner so that its base side surface is not in contact with the base of the door shelf or unless it is not in Contact with it in some sections. Preferably, it is provided that the retention part is arranged suspended, so that the retention part, regardless of the tolerances that are presented, is completely or partially suspended on the base, that is, on the base surface of the door shelf.

In another variant of the invention it is envisioned that the door shelf has a limiting means, in particular a wall, and that the retaining part, on its side facing the limiting means, has at least one rib or one or more projections that are located adjacently in the limiting means.

The mentioned friction rib, the projection or the projections can act as counter-supports, guaranteeing that the retention part is suspended on the base of the door shelf, that is to say that it is not supported, regardless of the tolerances that are presented.

In another variant of the invention it is envisioned that the first guide element is formed by a groove or by a projection, and that the second guide element is formed by a projection or by a groove, where the groove and the projection are designed so that The projection is slidably housed in the groove.

In another variant of the invention it is envisioned that the first guide element is arranged in a wall section that is directly or indirectly connected to the limiting means or to the wall of the door shelf.

By way of example, it is possible that the first guide element is arranged in a wall section that extends essentially parallel to the wall of the front side of the door shelf, where the wall section and the wall of the front side of the door shelf can be connected to each other through a bridge.

Preferably, the said projection is made in the form of a drop. For example, alternatively or additionally, it can extend in the longitudinal direction of the door shelf or of the limiting means. Through this drop form, especially advantageously, it is possible to guarantee the desired positioning of the retention part, in particular the suspended arrangement of the aforementioned retention part, regardless of the tolerances that arise.

In another variant of the invention it is envisioned that the retaining part, in its rear area of the base side, has a support rib that is used as loss protection. If a deformation of the limitation occurs, in particular of the wall on the front side of the door shelf, that support rib can be used as a protection against losses on the rear side of the retention part.

In addition, the present invention refers to a refrigeration and / or freezing apparatus with one or more door shelves that can be hooked on the internal door of the apparatus, where the internal door, as well as at least partially the shelf or The door shelves are made of plastic. Preferably, at least the part or parts of the door shelf that are adjacent to the inner door or that are connected thereto are made of plastic.

It is possible for example the combination of polypropylene door shelf and polystyrene inner door materials, polyoxymethylene door shelf and acrylonitrile butadiene styrene internal door, variants of those combinations, as well as other combinations of the materials. By using plastic they can be avoided

Clicking noises, as well as better engagement comfort can be achieved when adjusting for height.

In principle it is possible to combine different materials, for example transparent materials for one or more components of the door shelf with non-transparent materials for other components of the door shelf.

5 Thus, for example, it is possible to make the transparent retention part and the door shelf itself (without retention part) or its parts, such as the base plate and / or the wall of the front side and / or the lateral parts, of opaque material. The reverse case is also possible, that is, to make the retention part of opaque material and the door shelf itself or the mentioned parts thereof (base plate and / or cover of the front side and / or side parts) of transparent material .

10 The term "transparent" encompasses any kind of transparency or translucency. Correspondingly, the term "opaque" encompasses materials that do not possess such properties.

Preferably, the said cooling and / or freezing apparatus is made such that it has a door shelf according to one of claims 1 to 10, which can be hooked on the internal door. Preferably, several hitch positions are provided in the internal door, so that the door shelf 15 can be adjusted for height, as well as can be engaged in the various positions mentioned.

Furthermore, the present invention refers to a refrigeration and / or freezing apparatus characterized in that the apparatus has one or more door shelves according to one of claims 1 to 10.

The door shelves can be hooked on the door of the appliance. However, it is not a mandatory feature 20 of the present invention.

Other particularities and advantages of the invention are explained in detail through an exemplary embodiment represented in the drawing. The figures show:

Figure 4: a view of the wall on the front side of the door shelf in a view from the placement surface of the door shelf,

Figure 5: a sectional representation through the front side part of the retention part; Y

Figure 6: A perspective view of the front side section of the retention part.

30 Figure 1 shows a door shelf 10 according to the present invention.

The door shelf has a first side part 12 and a second side part 14, between which a wall 16 of the front side extends. The side parts 12, 14; as well as the wall 16, U-shaped surround the placement area of the door shelf 10. On the side parts 12, 14; on its upper side, a rod 20 is disposed which, like the wall 16 on the front side, serves to secure against a fall the product that must be refrigerated which is located in the door shelf 10.

The lateral parts 12, 14 and 16 can be made of one piece or they can also be composed of several pieces. Preferably, they are made of plastic.

As can be seen in Figure 2, the base plate 30 of the door shelf, which for example can be made as a glass plate, but can also be made of other materials, such as plastic, is inserted into a groove 17 on the front side of the anterior wall 16. Such a connection between the base 30 may also be possible with respect to the side parts 12, 14; that is to say that the base, as well as the glass plate 30, can be joined with the lateral parts 12, 14; as well as with the wall 16 on the front side, through a joint connection.

The reference sign 40 in Figure 1 indicates a retaining part that can move in a lateral direction. That retention part may be composed of plastic or other materials. The retention part, at

If centrifugal forces occur during the opening or closing of the door, it is used essentially to prevent as much as possible displacements of the product to be refrigerated in the door shelf 10, as well as to limit the area of movement. For example, it is possible to place a bottle, can or the like on the door shelf, then moving the retention part 40 until a movement of the bottle or can is no longer possible or is hardly possible.

As can be seen in particular in Figure 2, the retaining part 40 is not placed upside down on an existing profile, but is guided laterally. Thanks to this, the deformations and tensions that occur in the retention part 40 are minimal, avoiding the problem known by the state of the art, which, among other things, can lead to a breakage of the connecting element or the hook of the retention part.

As can be seen in particular in Figure 2, after the wall 16 on the front side of the door shelf 10 there is a bridge 19, which obliquely extends upwards. A wall section 19 'extends from the end area of that bridge 19, which extends essentially parallel to the wall 16 on the front side. In the area of the lower end of that wall section 19 'there is a projection 50 that extends towards the contiguous section of the retaining part 40, that is, towards the inner side of the door shelf 10.

The projection 50 is made in the form of a drop and forms a suspended housing for the retention part 40. The retention part 40 has a wall section 42 that has a recess or groove 43, in which the projection 50 is engaged in the form drop of wall section 19 '. On the other side of the wall 19 'extends at least one projection 44, for example two projections, of the retaining part 40. The wall section 19'; in this way, it is housed between two parts of the retaining part 40, in that case between the wall section 42 and the projection or the projections of the wall 44. Through the projection 50 which is housed in the groove 43 the retention part 40 is held in a certain position, in this example of execution in a suspended position. By properly selecting the guiding conditions, as well as the first and second guiding means, it is possible to safely prevent an undesired displacement of the retaining part 40. In the exemplary embodiment shown in this case, the first guiding means they are formed by the projection 50 and / or the wall section 19 '. The second guide means are formed by the groove 43 and / or by the wall sections or projections 42, 44 of the retaining part 40.

The reference sign 46 indicates a friction rib disposed on the front side of the retention part 40, which is used as a counter-support and ensures that the retention part is suspended on the base, as well as on the base plate 30 of the door shelf, regardless of the tolerances that arise. In the exemplary embodiment shown here, the retaining part 40, is thus arranged suspended through that construction. However, it is not a mandatory feature of the invention.

The friction rib 46 may be chamfered laterally. Instead of a friction rib, one or more projections can also be provided.

The reference sign 60 according to Figure 2 indicates a laterally chamfered support rib, arranged in the rear area of the retaining part 40, which is formed as retaining part 40 and is used as loss protection.

As can be seen in Figures 1 and 2, the first and second guide elements are arranged so that they are not visible from the front and from the top, so that as a whole a pleasant overall optical impression results.

The retaining part 40, as well as the wall 16 on the front side may be composed of the same material or different materials. Through a suitable combination of materials it is possible to avoid friction noise to a large extent.

Figure 3, in a sectional perspective view, again shows the wall 16 of the front side of the door shelf, the connecting bridge 19, as well as the vertical wall section 19 ', in whose area of the lower end is the 50 drop-shaped or ribbon-shaped projection. The projection 50 extends in the longitudinal direction of the wall 16. It can be carried out continuously or discontinuously.

In figure 4 the arrangement according to figure 3 can be seen in a view that starts from the base surface 30 of the door shelf 10.

In Figure 4 it can be seen that the wall section 19 'does not extend over the entire length of the wall 16 of the front side, so that one or more insertion areas are formed in which the retention part is fixed, where it can then move laterally on the wall section 19 ', as well as on the preferably continuous projection 50. With the reference sign 51, the insert chamfering is indicated in Figure 4

side, where this chamfering facilitates the insertion of the retention part 40, as well as the groove 43 of the retention part 40.

Figure 5 again shows the retaining part 40 in its section of the front side, in a sectional representation with the groove 43 extending in the lower area of the wall section 42, which, following the groove 43, it becomes a horizontal wall section 42 ', which consequently becomes a vertical section 42' ', on the front side, of the retaining part 40.

The reference sign 44 indicates a projection of the retention part which, in the inserted state of the retention part 40, is located adjacently in the wall section 19 '. As can be seen in the perspective view according to Figure 6, the retention part has two projections 44 spaced apart from each other, between which a free space is maintained. Between the wall section 42 and the sides of the projection 44 facing the wall section 43, the wall section 19 'of the wall 16 of the front side is introduced laterally. As shown in the upper part, in the area of the lower end of the wall 42, where it becomes the horizontal section 43, is the groove 43 that is used to house the projection 50.

In Fig. 5 the arrangement of the friction rib 46 of the retention part 40 is clearly shown again, with which, on the front side, the retention part 40 is located adjacently on the inner side of the wall 16 of the front side of the door shelf 10. In the manner explained, the friction rib, preferably laterally chamfered, is used as a counter-support, holding the retaining part 40 in the desired position.

The door shelf 10 according to the present invention may have connecting elements for engaging the door shelf 10 in connecting elements of the internal door. Therefore, it is possible that the shelf 10 is not fixedly arranged in the internal door of an apparatus, but may be removed or hooked, due to which it is also possible to adjust its height. To avoid noise by clicking, it is considered advantageous if the door shelf is composed of plastic, at least partially. The corresponding applies to the internal door. It is possible, for example, to combine a polypropylene door shelf with an internal polystyrene door, a polyoxymethylene door shelf with an internal acrylonitrile butadiene styrene door, etc. Other combinations are also possible, such as polypropylene door shelf with acrylonitrile butadiene styrene internal door or polyoxymethylene door shelf with polystyrene internal door, as well as other combinations of materials.

Through an appropriate combination of materials, improved coupling comfort is guaranteed.

As explained above it is possible to realize the retention part 40 and the adjacent parts of the door shelf, in particular the wall 16 on the front side, the bridge 19 and the wall section 19 ', so as to avoid the most possible friction noise when moving the retention part.

Through the design of the door shelf according to the exemplary embodiment shown here, an optically pleasing solution is achieved, which is only exposed to comparatively reduced loads, since the retaining part is not turned upside down, but is introduced in lateral form However, the retention part can move easily and without friction noise. In addition, it can be easily assembled and disassembled, offering good adjustment comfort. Instead of a retention part, of course, two or more than two retention parts can also be provided per door shelf.
