Definitions

  • the invention relates to a holding device for a shelf on a shelf wall, a connecting element according to the preamble of claim 12, a shelf according to the preamble of claim 13, and the use of the holding device in a piece of furniture according to claim 16.

This ensures that the retaining element securely remains in the retracted position, as long as this does not affect a magnetic force through the second connecting element.
  • the holding element of the first connecting element Due to the magnetic attraction between the connecting elements, the holding element of the first connecting element is automatically extended into the holding position, as soon as the connecting elements come into magnetically effective proximity, so that no additional step is required for this. If a plurality of first connecting elements are provided at different heights in the rack walls, then only those holding elements in the immediate vicinity of which there is a shelf with corresponding second connecting elements are in the extended holding position.

  • the projections for example, completely encircling.
  • a combination of materials, for example, take place in that the projections are formed of metal, which are then connected during injection molding with the rest, for example made of plastic housing 9.
  • metal flakes are much easier to plastically reshape, a second limiting element 22 can be formed in a particularly simple and stable manner.
  • these second limiting elements 22 can be deformed radially inwardly simply by means of cold or hot deformation, so that they project inward and form a boundary for the holding element 7. As a result, a particularly cost-effective production and assembly is possible.
  • Such protrusions or a snap hook can also in the illustrated embodiments of the second Connecting element 5 may be provided to allow a reliable fixation of the magnet 14.
  • the housing 9 at the opening of its first guide portion 10 may have rounded or chamfered edges in order to avoid tilting of the holding element 7 during extension and retraction.
  • the embodiments described and shown in the figures can also be used in general for the connection of furniture pieces, for example for the positioning and fixing of stacked boxes. Due to the magnetic force, the holding device can be spatially freely arranged on the furniture. This is especially true in combination with the above-described additional magnetic elements for mutual positioning of the furniture parts to be joined.
  • the holding element 7 of the first connecting element 4 may be wholly or partly magnetic, in which case the second connecting element 5 consists of a magnetically attractable material such as steel, iron, etc. It is also possible for both the second connecting element 5 and the retaining element 7 of the first connecting element 4 to be wholly or partially magnetically executed. In this case, the poles of the magnets are to be aligned so that the holding element 7 is used to the second connecting element 5, when the second connecting element 5 comes in the vicinity. In order to achieve a visually appealing and uniform surface and to protect the second connecting element 5 designed as a magnet from damage, the second connecting element 5 can be partially or completely covered by a cover, for example made of plastic.

Abstract

L'invention concerne un dispositif de retenue (1) pour une surface (2) de rayonnage sur une paroi (3) de rayonnage, le dispositif comprenant un premier élément de liaison (4) destiné à être agencé sur la paroi (3) de rayonnage et un deuxième élément de liaison (5) destiné à être agencé dans la surface (2) de rayonnage, au moins un des éléments de liaison (4, 5) comprenant un aimant (14) agissant par attraction sur l'autre élément de liaison (5, 4), afin de déplacer magnétiquement un élément de retenue (7) du premier élément de liaison (4) le long d'une direction d'extraction X d'une position de retrait rentrée dans une position de retenue sortie pour retenir la surface (2) de rayonnage sur la paroi (3) de rayonnage. L'invention vise à permettre un détachement simple et rapide des surfaces de rayonnage de la paroi de rayonnage, et à réaliser en outre un positionnement sûr des surfaces de rayonnage ainsi qu'une paroi de rayonnage esthétiquement plaisante. À cet effet, le premier élément de liaison (4) comprend un boîtier (9) et un élément ressort (8) qui est agencé dans le boîtier (9) et qui retient l'élément de retenue (7) dans le boîtier (9) dans la position de retrait rentrée et s'appuie d'une part sur une zone à section transversale (12) agrandie de l'élément de retenue (7) et d'autre part sur une zone à section transversale (10) rétrécie du boîtier (9).
