Description

Storage shelf for a piece of furniture or household appliance

The present invention relates to a shelf for a piece of furniture or household appliance according to the preamble of claim 1. The invention further relates to a piece of furniture or household appliance with such a shelf.

Shelfs of the generic type consist essentially of a support plate and a guided on this at the same time rotatably and translationally movable shelf, the rotatory and translationally movable mobility, an accessibility of otherwise difficult to reach areas in a storage space of a piece of furniture or household appliance such as one Office, kitchen, fridge or freezer.

For example, DE 42 1 6 765 A1 discloses a shelf equipped with a turntable, in which the turntable is installed directly in the base plate of the shelf.

From DE 10 2017 106 170 A1, a support that is positively guided relative to the support plate and that can be rotated and translated at the same time is known.

A disadvantage of these shelves known from the prior art is, on the one hand, the relatively complex assembly of such a shelf.

In addition, due to the relatively complex assembly, cleaning of the shelf is only possible in the assembled state, so that partial areas of the shelf can only be cleaned after the entire shelf has been dismantled beforehand.

The object of the present invention is to provide a storage shelf which can be built, dismantled and cleaned in a simpler manner in the body of a piece of furniture or household appliance.

This object is achieved by a shelf for furniture or household appliance with the features of claim 1.

The object is also achieved by a piece of furniture with the features of claim 17 and a household appliance with the features of the application. Proverb 18 solved. In addition, a method for mounting a Ablagebo dens is described in claim 19.

The shelf according to the invention has a support plate which is arranged in a fixed manner on a body of the furniture or household appliance, and a support which is positively guided relative to the support plate and is simultaneously rotatable and translationally movable.

Mutually facing bearing surfaces of the support plate and the tray each have at least predominantly closed, circumferential grooves in which rolling elements are guided. The support plate can be detachably attached to the body of the furniture or household appliance.

At least one fastening area for releasable fixation of the support plate on the body of the furniture or household appliance is formed on the support plate. The shelf can be fixed to the support plate without tools.

A shelf formed in this way can be assembled in a simple manner and mounted on the body of a piece of furniture or household appliance.

The tool-free fixing of the shelf on the support plate also enables cleaning and disassembly of the shelf in a simple manner.

In addition, the storage shelf can be manufactured and transported inexpensively by eliminating a factory pre-assembly compared to storage shelves known from the prior art.

Advantageous embodiments of the invention are the subject of

Dependent claims.

According to an advantageous embodiment of the invention, the Laufril len are integrated into the bearing surfaces of the support plate and the tray. This enables a low overall height of the shelf.

According to an alternative, also advantageous embodiment of the invention, the grooves are attached to the bearing surfaces of the support plate and the Abla ge, in particular integrally or screwed. As a result, the support plate and the shelf are much easier to manufacture, since no grooves are formed here and openings for the guide channel and the pin have to be made in the support plate or the shelf.

According to an advantageous embodiment of the invention, a pin protruding in a guide channel of the support plate is arranged on the bearing surface of the shelf. The pin can advantageously have a mushroom-shaped head.

This enables simple and reliable guidance of the tray relative to the support plate for the translatory movement.

According to a further embodiment variant, the guide channel has an undercut, which is engaged behind by a cam of the pin in the assembled state of the support on the support plate. The undercut can be formed over the entire area of the guide channel.

The undercut is advantageously formed only in the region of the guide channel that comes into engagement with the pin when the tray moves.

In the starting position, the tray can be removed from the support plate without great effort, and the tray is secured to the support plate during the movement.

This ensures a vertical fixation of the shelf on the support plate in a simple manner.

To facilitate tool-free assembly of the support plate with the tray, the guide channel according to a preferred embodiment has a Mon day range with at least one locking element into which the pin is insertable bar.

In order to prevent unintentional sliding out or pivoting of the tray relative to the support plate from a starting position, a taper is provided at one end of the guide channel, with which the pin is stable in a position in which the tray is positioned in a starting position relative to the support plate is. This taper is preferably formed by the free ends of each other against lying locking elements.

The locking elements thus perform two different tasks, namely on the one hand the releasable fixation of the pin in the guide channel in the vertical direction and the second the above-mentioned pre-fixing of the pin in the position holding the tray in its initial position.

According to a further advantageous embodiment variant, the guide channel is designed as a separate component which can be mounted in a recess in the support plate which is adapted to the outer contour of the guide channel.

The guide channel preferably has at least one latching lug on its outer circumference, which can be latched in a latching recess in the recess of the support plate, so that the guide channel can be inserted and latched into the recess in the support plate in a simple manner.

According to a further preferred embodiment variant, the outer circumference of the guide channel is designed asymmetrically and with a

Provide positioning piece so that the taper of the guide channel can only be used in the predetermined position in the support plate during installation.

According to one embodiment variant, the storage shelf additionally has a rolling element cage for folding the rolling elements and the carrier plate for correct positioning of the ball cage at least one positioning element.

According to a further embodiment variant, the fastening area of the support plate has at least one receptacle for folding a fastening element.

The fastener is according to a preferred one

Design variant designed as a suction cup, the receptacle being designed as a suction cup receptacle for folding the suction cup.

This variant is particularly suitable for use in

Refrigerators with glass shelves, on which such suction cups ensure a good FHalt. According to an alternative embodiment variant, at least one of the receptacles is designed as a bolt receptacle for carrying out a fastening element formed as a bolt.

This variant is particularly suitable for use in furniture with wood or plastic floors.

According to yet another alternative embodiment variant, the fastening area has at least one adhesive surface on which an adhesive element for fixing the support plate to a floor of the furniture or household appliance can be attached.

As an adhesive element, for example, a double-sided adhesive strip is possible.

The furniture according to the invention is characterized by a shelf as described above.

The household appliance according to the invention is also characterized by a storage shelf as described above.

The inventive method for mounting a shelf has the following steps: a. Attaching a support plate to a body of the furniture or household appliance by means of one of the releasable fastening elements mentioned above; b. Placing a rolling element cage with rolling elements mounted therein on the support plate; c. Place a shelf with a bearing surface on the rolling element cage, a pin protruding from the bearing surface of the shelf being inserted into the guide channel.

Optionally, step a1 is followed by step a1, inserting a guide channel into a recess in the support plate, provided that the guide channel is designed as a separate component. In this case, step a1 can also be carried out at the factory, so that this step is not necessary when assembling the shelf on site at the end customer.

The guide channel can also be integrally formed on the support plate.

Preferred exemplary embodiments of the invention are explained in more detail below with reference to the accompanying drawings. Show it:

18 shows a flat-rate device with shelves according to the invention.

In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. relate exclusively to the exemplary representation and position of the shelf, the support plate, the shelf, the guide channel, the pin selected in the respective figures and the same. These terms are not to be understood as restrictive, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.

In Fig. 1, reference number 1 overall designates a variant of an inventive shelf.

As shown in Fig. 2, the shelf 1 has a support plate 2 and a relative to the support plate 2 positively guided, at the same time rotatable and translatory movable shelf 3.

The support plate 2 is, as exemplarily and schematically shown in FIGS. 17 and 18, attached to a body 13, 14 of a piece of furniture 1 1 or a household device 12, for example an office, kitchen, refrigerator or freezer.

As is further shown in FIG. 2, facing bearing surfaces 21, 33 of the support plate 2 and the tray 3 have respective, at least predominantly closed, circumferential grooves 22, 34, in which rolling elements 10 are guided. The rolling elements 10 are received in a rolling element cage 4. The rolling element cage 4 in the preferred embodiment shown here has an approximately circular base body 41, from which webs 42 extend radially inwards and outwards, at the ends of which rolling element receptacles 43 are formed, in which the rolling elements 10 are held, so that they are held in easy to accomplish between the shelf 3 and the support plate 2 can be set ge and are secured against falling out during operation.

The rolling element receptacles 43 are shaped in such a way that the rolling elements 10 are held securely. The rolling element cage 4 can also have other geometries and other arrangements of rolling element receptacles 43.

The support plate 2 is detachably attached to the body 13, 14 of the furniture 1 1 or household appliance 12.

For this purpose, two fastening areas 25 for releasably fixing the support plate 2 to the body 13, 14 or to a fixed part, for example a floor, of the furniture 1 1 or household appliance 12, are integrally formed on the support plate 2, as shown in FIG. 2.

It would also be conceivable to only form such a fastening region 25 on the support plate 2.

The tray 3 can be fixed on the support plate 2 without tools. This is before given, as shown in FIGS. 2, 3 and 6, on the bearing surface 33 of the tray 3 in a guide channel 5 of the support plate 2 projecting pin 6 is arranged. The pin 6 is preferably captive on or in the bearing surface 33 of the tray 3 fixed or integrally formed on the tray 3.

For the vertical fixing of the pin 6 in the guide channel 5, the latter preferably has an undercut 55, which is engaged behind by a cam 62 of the pin 6 in the assembled state of the shelf 3 on the support plate 2.

The guide channel 5 is, as can be clearly seen in FIGS. 2, 7 and 8, preferably be designed as a separate component which can be mounted in a recess 23 of the support plate 2 which is adapted to the outer contour of the guide channel 5. To fix the guide channel 5 in the recess 23, the guide channel 5 is preferred, as shown in FIGS. 7, 8 and 5, provided with at least one locking lug 56 which can be locked in a corresponding locking recess 29 in the recess 23 of the support plate 2.

As shown in FIGS. 7 and 8 further, the guide channel 5 has a mounting area 53 with at least one latching element 54, into which the pin 6 can be inserted in a simple manner.

The mounting area is the outer contour of the cam 62 and the neck area 61 of the pin 6 is designed accordingly, so that when the shelf 1 is put together after inserting the guide channel 5 into the support plate 2, the tray 3 is placed on the support plate 2, the no 62 of the pin 6 plunges into the mounting area 53 of the guide channel 5.

A complete assembly of the shelf 3 can be indicated to the user visually or acoustically by a “click” sound. In this embodiment, there is no undercut in the assembly area 53, so that both assembly and disassembly of the shelf 3 can be carried out without great effort.

After assembly, the shelf 3 can move translationally along the guide channel 5 away from the assembly area 53. The cam 62 of the pin 6 reaches the area vertically below the undercut 55, shown in FIG. 8. This ensures that the tray 3 is held securely on the support plate 2 during a movement.

As shown in Fig. 8, at one end of the guide channel 5, a taper 58 is provided with which the pin 6 is stable in a position that positions the tray 3 in an initial position relative to the support plate 2.

This ensures that the tray 3 does not move unintentionally out of an initial starting position without the application of force.

In the embodiment variant shown here, the taper 58 is formed by the free ends of locking elements 54 arranged opposite one another, the spacing d ₂ (width of the taper) being slightly less than a distance di (width of the guide) between mutually opposite regions of the undercut 55.

In order to ensure correct positioning of the guide channel 5 in the recess 23, the outer circumference 52 of the guide channel 5 is formed asymmetrically by forming a positioning piece 57. The positioning piece 57 is formed in the embodiment shown here at one end of the guide channel.

It is also conceivable to provide the outer circumference 52 of the guide channel 5 at another position with a positioning piece 57.

It is important that the installation of the guide channel 5 can only be carried out in a predetermined orientation in order to ensure the fixation of the pin 6 and thus of the tray 3 in the starting position.

When the guide channel 5 is inserted into the support plate 2, the insertion depth is limited by a circumferential undercut 51 which in the assembled state rests on the bearing surface 21 of the support plate 2.

In the above-mentioned initial position of the tray 3, the pin 6 is held in the mounting area 53 of the guide channel 5.

In order to move the tray 3 from the starting position into a loading and unloading position, a force on the tray 3 is accordingly necessary.

The grooves 22, 34 are shaped such that when force is exerted on the shelf 3 in the horizontal direction, the shelf 3 from a starting point corresponding to the orientation of the shelf 3 shown in FIG. 1 relative to the support plate 2 rotated into a 180 ° Loading or unloading position is movable, in which the tray 3 is not only rotated by 180 °, but is also translated by a distance defined by the length of the guide channel 5 to facilitate loading and unloading.

To disassemble the shelf 3, the shelf 3 is raised in the starting position shown in FIG. 1 with little effort, so that the cam 62 of the pin 6 leaves the assembly area 53 and thus disengages from the guide channel 5. As shown in FIGS. 2, 3 and 6, the tray 3 on its underside 33 has a plurality of pins 35, with which an inclination of the tray 3 can be prevented with one-sided load.

As shown in FIGS. 2 to 5, the fastening area 25 of the support plate 2 has at least one receptacle for folding a fastening element.

2 to 5, several shots are shown that allow different fastening options of the support plate 2 on a floor 15 of the furniture 1 1 or flat-rate device 12.

Thus, the fastening region 25 has at least one receptacle, which is designed as a suction cup receptacle 26 for folding a fastening element designed as a suction cup 7.

The fastening area 25 also has at least one receptacle, which is designed as a bolt receptacle 24 for carrying out a fastening element designed as a screw bolt 9.

As shown in FIG. 4 in particular, the fastening area 25 has at least one FHaft surface 27, on which a flute element 8 for fixing the support plate 2 to a floor 15 of the furniture 11 or fluff device 12 can be attached. The flaft element 8 is designed in particular as a double-sided adhesive element.

In the two embodiment variants shown in FIGS. 9 to 1 6, the grooves 122, 134, 222, 234, in contrast to the embodiment variant shown in FIGS. 1 to 8, are not integrated in the bearing surfaces 21, 33 of the support plate 2 and the shelf 3 , but as separate groove bodies 101, 102,

201, 202 formed, which are attached to the respective bearing surfaces 121, 133, 221, 233 of the support plate 120, 220 and the shelf 130, 230.

Thus, in FIGS. 9 to 12, an embodiment variant of a storage shelf 1 is shown, in which the grooves 122, 134 are firmly bonded to the support plate 120 and shelf 130, in particular by gluing. In the embodiment variant of a storage shelf 1 shown in FIGS. 13 to 1 6, the running grooves 222, 234 are screwed onto the support plate 220 and the storage shelf 230.

As shown in Figures 1 1 and 12 or 15 and 1 6, the

Grooved body 101, 102, 201, 202 for this purpose on their respective bearing surface 121, 133, 221, 233 of the support plate 120, 220 and the shelf 130, 230 side facing flat to provide a sufficiently large adhesive or contact surface with to create the bearing surfaces 121, 133, 221, 233 of the support plate 120, 220 and the shelf 130, 230.

On the side of the tread body 101, 102, which faces away from the respective bearing surfaces 121, 133, 221, 233 of the support plate 120, 220 and the shelf 130, 230,

201, 202, the actual grooves 122, 134, 222, 234 are formed.

In the screw-on variant of the shelf 1, as shown in FIGS. 13 to 1 6, additional screw receptacles 206 are provided in the tread bodies 201, 202 through which screws 205 can be passed. The

Screws 205 are screwed for mounting the tread bodies 201, 202 through the screw receptacles 206 into screw holes 207 provided therefor in the support plate 220 and the shelf 230.

As shown in FIGS. 10 and 14, in these embodiment variants, the respective groove bodies 101, 102, 201, 202 are preferably in the center

Recesses 103, 104, 203, 204 for receiving and positioning the guide channel 150, 250 and the pin 1 60, 260 formed.

The guide channel 150, 250 and the pin 1 60, 260 are for final fixation after insertion or also clipping into the respective recesses 103, 104, 203, 204 on the bearing surfaces 121, 133, 221, 233 of the support plate 120, 220 and the shelf 130, 230 cohesively or fixed by screwing Ver.

The shape and function of the grooves 122, 134, 222, 234, the guide channel 150, 250 and the pin 1 60, 260 corresponds essentially to the execution variant described above with reference to FIGS. 1 to 8. In contrast to the embodiment variant described in FIGS. 1 to 8, in the embodiment variants shown in FIGS. 9 to 16 the support plate 120, 220 and the shelf 130, 230 are much easier to manufacture, since there are no molded grooves and openings for the guide channel 150,

250 and the pin 160, 260 in the support plate 120, 220 or the tray 130,

230 must be introduced.

The improvements described above make it easy to assemble and disassemble the shelf 1 and, at the same time, space-saving transport. This enables assembly and disassembly by the user, which is particularly advantageous in the case of retrofitting a shelf 1 in existing furniture 11 or leisure appliances 12.

The following steps are carried out to assemble a shelf: a. Attaching a support plate to a body of the furniture or household appliance by means of one of the releasable fastening elements mentioned above; b. Placing a rolling element cage with rolling elements mounted therein on the support plate; c. Place a shelf with a bearing surface on the rolling element cage, a pin protruding from the bearing surface of the shelf being inserted into the guide channel.

If the guide channel 5 is designed as a separate component, this is done after step a. as a further step: a1. Insert the guide channel in a recess in the support plate.

This step a1 can be carried out both when assembling the shelf on site at the end customer and at the factory, so that this step is omitted when assembling the shelf on site at the end customer.

So that the shelf 1 is always correctly installed, it is also necessary in addition to the above-mentioned assembly steps that the ball cage 4 is positioned exactly on the support plate 2. For this purpose, the support plate 2 has, in this exemplary embodiment, two positioning elements 20 on its bearing surface 21 facing the shelf 3. However, it can also be only one or more than two positioning elements. The ball cage 4 is placed on the support plate 2 in such a way that the rear outer rolling element recesses 43 bear against the positioning elements 20. This ensures that the rolling elements 10 grooves 22, 34 move perfectly in the barrel. The correct positioning of the tray 3 on the Ku gelkäfig 4 is ensured by the interaction of pin 6 and guide channel 5. If the grooves 122, 134, 222, 234 are formed separately, as shown in FIGS. 9 to 16, step a takes place. or between steps a. and b. still the steps d. Attaching a tread body 102, 202 to the support plate 120, 220 and e. Attaching a groove body 101, 201 to the position 130, 230.

To attach the tread body 101, 102, 201, 202 to the support plate 120,

220 and the shelf 130, 230, the groove body 101, 102, 201, 202 are preferably glued or screwed to the support plate 120, 220 and the shelf 130, 230.
