Definitions

  • the invention relates to a connecting element according to the preamble of claim 1, a connecting system of connecting elements according to claims 22 and 50 and a refrigerator with such connecting elements.
  • the connecting element and the connecting systems are preferably used in the interior of a refrigerator for fastening the shelves, but they can also be used for fastening components of furniture, such as shelves and cupboards.
  • Refrigerators are known in which recessed receiving strips are provided for fastening the shelf compartments to two opposite side walls. Such a side wall is shown in Fig. 8.
  • the receiving strips (20) extend almost over the entire depth of the shelf compartment, which usually consists of wire-shaped bars that are connected to one another to form a grid. Lateral bars of these shelf compartments are either placed on the strips or inserted into the refrigerator from the front.
  • the inner housing of a refrigerator facing the cold room side is usually manufactured as a one-piece plastic injection-molded part for production-related and food-hygiene reasons. Between this one-piece molded plastic part and its foam insulation on the back, it is usually
  • CONFIRMATION COPY se a composite material that additionally stabilizes the plastic injection molded part.
  • the plastic molded part is made as thin-walled as possible to save material.
  • the connection systems consisting of mounting strips have the advantage of good stability even with small wall thicknesses, but they are also disadvantageous. They require a considerable amount of material in the production of the side walls and the application of their rigid foam insulation, since the structure of multiple strips arranged one above the other extends almost over the entire length of each side wall.
  • the production of a large-area multiple strip structure requires a not inconsiderable amount of tools. In particular, there is an increased effort for mold construction in the production by injection molding.
  • the multiple strip structure is also unsanitary, since the large number of cutouts and projections is difficult to clean, which is particularly critical when storing food.
  • the multiple strip structure also results in reduced insulating properties of the side wall, since the multiple strip structure ultimately behaves like a number of heat-conducting fins, which “improves” the heat exchange between the cold room side and the outside of the refrigerator.
  • the connecting element is arranged on its rear side on a wall and a receiving section is also provided for connection to a component
  • the receiving section can be individually adapted to the requirements of the shelf compartment without having to meet the manufacturing requirements to be taken into account when manufacturing a wall, in particular without to have to pay special attention to the thin walls of the wall.
  • the wall can then be made flat outside the connection point with a connecting element.
  • the connecting element can thus simultaneously be used for connection to the wall as well as for the connection to a component.
  • the receiving section of the connecting element can be used universally for different parts.
  • the connecting element is removably held on the wall, so that it can be easily replaced. So not only the wall, especially in the area of the connecting element, can be cleaned completely and easily after a few assembly steps.
  • a particularly advantageous embodiment of the invention provides a first variant, in which the back of the connecting element is held in a form-fitting manner with clamping forces on the wall, so that no additional fastening elements are required.
  • a particularly quick assembly can be achieved with this first variant if a recess is provided on the rear of the connecting element, into which a projection engages on the wall.
  • the connecting element according to this first variant can be easily pushed onto the projection on the wall parallel to the wall assigned to it.
  • the connecting element is connected to the component via a snap or clamp connection.
  • a shelf can be attached to the connecting element quickly and easily, which also enables the connecting element to be preassembled to facilitate handling on the shelf to be positioned.
  • the connecting element preferably additionally has a support section which can be used to additionally support the component on the connecting element, which increases the stability and the load-bearing capacity of the shelf.
  • the connecting element has at least one cylindrical receiving section, which is open on the side opposite the rear side, the one rod-shaped section of the component, such as a shelf of a refrigerator, can accommodate.
  • the rod-shaped section is locked on the cylindrical receiving section and can be removed via a tapered section on the cylinder wall side.
  • two cylindrical receiving sections are provided on the side opposite the rear wall, which are arranged on two sides of the connecting element and into which a rod can be inserted, the longitudinal extent of which is parallel to the longitudinal direction of the cuboid recess, a continuous support section being arranged above the receiving sections.
  • the connecting element is held on the wall with its rear side, in that a part of the connecting element is pushed perpendicular to the wall onto a projection of the wall or inserted into a recess in the wall.
  • a pushing in or pushing on perpendicular to the wall makes it possible to produce a large-area, form-fitting contact between the fastening element and the wall in the main loading direction with a very simply designed fastening element.
  • a particularly advantageous development of the alternative second variant of the invention provides that the receiving section is formed by an opening in the connecting element, which extends essentially parallel to the axis, along which the connecting element onto the holding projection or into the holding recess can be inserted. Due to the possibility of inserting the component perpendicular to the wall into the connecting element, a connection between the component and the fastening element can be made very easily, and there is also the possibility of being perpendicular anyway to use the tapered struts of a grid-shaped shelf for fastening between the component and the connecting element.
  • a particularly advantageous development of this second variant provides that the opening forming the mounting portion completely penetrates the connecting element. It is thus possible to guide the connecting element on the component in such a way that the connecting element can be displaced relative to the component and so that engagement with the wall can be established or canceled in a simple manner.
  • the tube-shaped structure has further disadvantages, particularly in refrigerators.
  • the tube-shaped structure is disadvantageous with regard to the problem-free arrangement of the shelving compartments according to the user's wishes.
  • the shelves can only be installed and removed by pulling out or inserting the shelf compartments in a drawer-like manner through the door of the refrigerator so that they come into or out of engagement with the receiving strips.
  • the need to pull this out is impractical.
  • the door of the refrigerator swings open in the direction of the kitchen wall, or if the refrigerator is arranged in the corner area of an angle kitchen, for example, so that the refrigerator door cannot be opened much more than 90 °, the following problem arises. In this case, the compartments in the refrigerator door may protrude into the area through which the shelf compartments must be pushed for removal and installation, even when the refrigerator door is fully open.
  • the inner housing of the refrigerator cannot be designed freely in the area of the door as long as the shelf compartments can be pushed in through the door opening.
  • the sealing flange facing the door must be designed so that it does not protrude inwards and hinder the ability to insert the shelf compartments.
  • the holding strips of the shelf compartments are arranged at a large distance from one another to avoid these disadvantages, this is also unsatisfactory. Installation and removal of the shelf compartments is then no longer dependent on the ability to insert the shelf compartments through the door opening. Because the shelf compartments can be tilted into the diagonal at a large distance from the mounting rails in the interior of the refrigerator and then easily removed through the door opening or installed in the opposite direction. In this case, however, the variability of the arrangement of the shelf compartments is restricted. Because in order to make it possible that the shelf compartments inside the refrigerator can be tilted from their horizontal position into a diagonal and vice versa, a clear distance between the superimposed mounting strips is essential.
  • connection system for connecting shelves to furniture such as a refrigerator, which not only can take advantage of the advantages of the fastening elements according to the invention, but also allows shelves to be attached very closely to one another to allow for simple assembly at the same time.
  • connection system with the features of claim 22.
  • Advantageous refinements of the connection system according to the invention are specified in subclaims 23 to 49.

  • a connection system designed in this way enables each individual shelf to be completely disengaged from the walls for disassembly, despite the fact that the optional fastening points for the shelves are very close together. The shelf can then be tilted and easily removed from the refrigerator. Nevertheless, the attachment is easy and quick to use. There are no strength problems even with thin-walled side walls.
  • all the guides and connecting elements are matched to one another in such a way that all connecting elements assigned to the component can be displaced on the component in such a way that they disengage from the Come wall, whereby the component comes free from the walls, so that it can be positioned in another place or removed entirely.
  • the connecting elements By pushing the connecting elements back on one side, the component is either completely free in the horizontal position or in any case only has to be tilted by a small amount in the diagonal direction in order to be completely free.
  • a further advantageous embodiment of the connecting system according to the invention provides that at least on one side of the component all guides and the connecting elements assigned to them are coordinated with one another in such a way that at least on this one side of the component all connecting elements can be displaced on the component in such a way that the component first comes free from the wall on this one side, whereupon the remaining connecting elements can also be brought out of engagement with the wall by moving the component, so that the structural part is released from the walls on both sides.
  • the component is a shelf
  • the shelf only has to be elaborately designed on one side in order to close the gap to the wall there as well.
  • a noticeable gap between the shelf and the wall must only be accepted on one side.
  • connection elements which only disengage from the walls in a second step by moving the component relative to the walls Bring wall and coordinate the projections or recesses of the wall associated with these connecting elements so that the component can be tilted after it has come free on one side of the wall.
  • This tiltability makes it possible on the side on which the component is first brought out of engagement with the wall by moving the connecting elements, to make do with a smaller displacement path of the connecting elements. In this way, the distance between the shelf and the wall can be further reduced even without special design of the component or shelf.
  • an advantageous embodiment of the fastening system according to the invention provides that the guide is formed by a strut of the grating and preferably by a main strut of the grating.
  • the guide can then be produced in a simple manner by dispensing with a strut in the region of the outer edges of the grating, as a result of which a free section suitable for guiding is available on the main strut of the grating.
  • the component can also be supported on these connecting elements perpendicular to the wall. This is particularly important if the component is to be clamped between the walls. It is then possible for the elastic bracing to support the component against the force of a spring element at the bottom of the blind hole of this connecting element.
  • the connecting element or the connecting elements are permanently attached to one side of the component, preferably by pressing, gluing, locking or injection molding. Furthermore, it can be provided that at least on one wall side the projections or recesses of the wall are designed such that they can only be brought into engagement with connecting elements which are provided for fastening on this wall side. In this way, protection against assembly errors can be achieved, in particular if different types of fastening elements are provided for different walls.

If the dimensions are correct, the KHpp then clamps in the installed position between the adjacent fastening element and the guide stop.
  • the at least one leaf spring (of the clip) is advantageously designed in the manner of a clamped cantilever and at the same time the extension of the clip along the axis of the guide element at the clamping point of the leaf spring is less than at the free end of the leaf spring. Between the two side edges of the KHpp, a wedge effect is created when the clip is inserted, which allows the spring to be tensioned with little effort.
  • the KHpp designed in this way can be very easily mounted on the guide, since first its front section can be attached to the guide element with almost no tension and then the spring tension of the clip is inevitably produced by the further pressing on, without the pressing being associated with difficulties and during Press on the KHpps must be taken care of the leadership.
  • an opening is made at least on one leg of the KHpps, but preferably on both legs, at the free end of the leg.
  • the opening is preferably designed so that the blade of a flat screwdriver or similar tool can be attached. This makes it possible for people with only small forces, especially older people, to easily remove the clip if necessary using an auxiliary tool.

It is not necessary, or at most a very slight tilting of the grating, in order to be able to raise or lower it.
  • the fastening elements 37 are pushed back to their original position along the strut 27 a that is inserted into them. Now the grating can be pushed back or pushed open with the fastening elements 37 onto the wall projections 38 assigned to the new position by simply pushing it down.

Abstract

La présente invention concerne un élément de fixation permettant la fixation simple, bon marché et stable de composants entre deux surfaces opposées et se faisant face. L'invention concerne en outre différents systèmes de fixation avec lesquels on peut exploiter au maximum les avantages offerts par les éléments de fixation selon l'invention et qui, en particulier lorsqu'ils sont utilisés dans des réfrigérateurs, permettent un retrait ou un changement d'emplacement simple et rapide de rayons, en particulier de grilles. Les systèmes présentés offrent la possibilité, en particulier lorsqu'ils sont utilisés dans des réfrigérateurs, de bloquer le composant à fixer entre les parois de sorte que les vibrations partant du compresseur ne puissent entraîner aucune vibration indésirée au niveau dudit composant, en particulier de la grille.
