Description

Rotatable wall unit pull-out

The present invention relates to a cabinet with a body, a shelf and an adjustment device, by means of which the shelf is linearly displaceable and a swivel joint about the axis of rotation of which the shelf is rotatably mounted on the adjustment device according to the preamble of claim 1.

In such a cabinet there is a constant need to reach stowed objects which are located in a rear area of the cabinet in a simple manner. If the cabinet is a base cabinet, can For example, a drawer system can be provided which can be pulled out of the cabinet and at least partially transports the shelf out of the body of the cabinet. If the cabinet is an overhead cabinet, a pull-out only helps to a limited extent, since the objects, which are located, in particular, in a rear central part, are still difficult to reach.

The present invention is based on the object of specifying a cabinet which can be used both as a top cabinet and as a base cabinet, with the accessibility to the rear areas of the shelf being easier than in the prior art.

According to the invention, the object is achieved by the characterizing features of claim 1.

According to the invention, it can be provided that at least one holding mechanism is provided which is designed to reversibly fix the tray in a predefined rotational position, having a resilient receptacle and a holding element that can be reversibly fixable in the receptacle.

The two parts of the holding mechanism, in particular the resilient receptacle and the holding element, can jointly fix the rotatably mounted tray in at least one position. This can be the case in particular when the reversibly fixable element is arranged in the resilient receptacle.

A first part, for example the resilient receptacle, can be provided on a static part of the shelf or the adjustment device. The other part, for example the holding element, which can also be referred to as the engaging element, can be arranged on a rotatable part of the shelf, in particular the rotatable shelf. Particularly preferably, the holding element can be attached to the rotatable part of the rotary joint and / or the resilient receptacle be arranged in a static part of the swivel joint. In principle, the arrangement can also be reversed.

A static part of the shelf or the swivel joint can be an area on the adjustment device or the swivel joint which is provided to accommodate the swivel joint or the rotatable part of the swivel joint for the rotational movement of the shelf or is connected to it.

This can be pulled out of the cabinet with a portion of the adjusting device that can be pulled out of the cabinet and / or form a base on which the swivel joint / the rotatable part of the swivel joint is arranged. The static part can, for example, be an extendable plate or be arranged on it.

The holding mechanism can also be used as a means for positioning, fixing or holding means.

The resilient receptacle can also be referred to as a guide element and / or driver and / or shaped spring and / or receptacle.

The retaining element can also be referred to as a removable element or an engaging element.

According to the invention, an adjusting device can therefore be provided, by means of which the shelf is linearly displaceable and rotatably mounted about an axis. As a result, a rear area of the shelf, in particular after the shelf has been pulled out (linear displacement), can be more easily accessible from the side or from the front by rotating the shelf through any angle of, for example, 90 ° or 180 °. The invention is implemented at least when a rotatable pull-out is provided (shelf).

The adjusting device can in principle be designed in one piece or in several pieces. The pull-out device can be used in particular for linear displacement of the would be provided, preferably a complete pull-out availability of the tray is provided.

It is particularly preferably provided that the adjustment device has a pull-out device, in particular a shear or cross pull-out or a rail pull-out, for linear displacement of the shelf.

The shear or cross extension can be formed with one or more shear units or elongated means connected in series, wherein a shear unit has at least two means, in particular arms, connected to one another in an articulated or displaceable manner at one point or along an axis. Particularly preferably, a shear or cross extension is formed with at least two shear units, which can be connected to one another via their respective ends. For example, a rotating device can be provided in an end area of the shear or cross extension, by means of which the shelf can be rotated relative to the body, in particular about a (vertical) axis.

The rail extension can be fastened / lockable both on the two side walls of the body and on the rear wall, the cover and / or the bottom of the body. The rail extension can, for example, also be provided as one or more rails which are delivered / connected to / connected to the shelf in a freely adjustable area between the side walls of the shelf, for example from below. Here, instead of being attached to the side walls, the rail extension can also be attached to at least one of the other three named areas of the body. This can in particular increase a maximum width of the shelf within the body, since no space is required for the rail extension on the sides of the shelf or the adjusting device. For a particularly optimal use of space, the shelf can roughly correspond to the basic shape of the body. This can in particular be a square or rectangular shape. The size of the shelf, especially if it is a square or rectangular basic shape, can be so large that a free rotation of the shelf within the body in a retracted position is prevented by the side walls and the rear wall. In such a case, free rotation is only possible if the shelf is guided out of the body by a linear displacement of the adjustment device or the pull-out device so that the corners of the shelf 11 come past the side walls of the body during rotation. This is ensured in particular when the shelf 11 is completely led out of the body, or the shelf 11 is so much smaller than the base area of the body that it can be freely rotated even when the shelf is partially removed from the base body.

The present invention is intended in particular to make a contribution when a free rotatability of the shelf within the body is fundamentally not possible due to the dimensions of the shelf.

It is preferably provided that the adjusting device is attached to an inner rear and / or side wall of the body. As a result, the adjustment device can be provided completely in the interior of the body. In particular with a simultaneous attachment to the rear and side walls or rear wall, cover and / or base, an increased strength of the anchoring of the adjustment device on the body can be provided, since especially in the extended state a support filled with heavy filling material has an increased leverage effect on the connecting elements between the Adjusting device and the body can exercise. It can expediently be provided that the adjusting device has locking means which detachably fix the shelf and / or the adjusting device in an extended position. In order to enable a smoothly rotatable shelf with respect to the body, it may be necessary to pull the shelf out of the body at least so far that the preferably angular shelf can be guided past the side walls of the body during a rotary movement. Should the adjustment device be at least partially returned in the direction of a retracted position of the shelf in the body, for example through contact with an operator, free rotation of the shelf may be hindered. By means of the locking means, the shelf can be fixed in an extended position in which the drawer protrudes far enough from the body to enable it to be freely rotated. In this way, damage to the body wall caused by rotating the shelf can be prevented.

Particularly preferably, it is provided that the locking means has at least one, preferably spring-loaded, roller which engages over or engages behind a body wall in the area of the opening of the body. In principle, any desired locking means for locking the shelf or the pull-out device in an extended position can be provided, which can be released again in a simple manner in order to return the shelf to the body of the cabinet without great effort.

According to one embodiment, at least one roller or an overlapping or engaging element can be provided, which is supported on any body wall against a pull-in direction of the shelf in a retracted position inside the body. This can be, for example, a front edge of a side wall, a cover or a base of the body or an outside of the side wall, the base or the cover of the body. In both cases, reaching over or reaching behind leads to a resistance or a holder / holding of the adjustment device as a whole, which prevents the shelf from being freely returned to a retracted position inside the body. The roller can in particular be spring-loaded, whereby it can be returned to a starting position by a user by overcoming a corresponding counter-pressure on the shelf or the pull-out device, which can enable the shelf to be adjusted from the extended position to the retracted position within the body.

To release a lock of the shelf, for example by means of the roller, a release mechanism can also be provided which, when actuated, moves the roller or the lock from the overlapping or rear-reaching working position back into a retracted rest position, which allows the shelf to be adjusted from the extended position to can release the withdrawn position within the body. An opening can basically be the area in which a cabinet door or a panel is usually arranged in order to cover it.

According to a development of the invention, it is particularly expedient that the adjusting device has a rotating device for the rotatable displacement of the shelf. In principle, the rotating device can be a bearing, a turntable or some other element which enables the tray to be rotated with respect to the adjusting device. In order to provide as large a support surface as possible, which can absorb forces in particular when tilting sideways, the rotating device can be designed as a plate or double plate, with one of the two plates being attached to the adjusting device and the other to the shelf in particular in the case of the double plate. The two plates of the double plate arrangement can be rotated with respect to one another, whereby a sufficiently large support area is provided which, when the support is loaded on one side or when one side of the support is pulled down, absorbs the forces. takes and protects or spares the corresponding bearing or bearings.

In particular, for a defined rotatability of the shelf, it can be provided that the rotating device is designed to displace the shelf in a rotating manner between at least two orientations. For example, it can be useful to define a first position in which the tray is in its starting position. The starting position can in particular be the position in which the shelf can be inserted into the body without any problems. In this position, for example, a side edge of the body can be aligned approximately parallel to a side edge of the shelf. A second orientation can be provided at any desired (rotational) angle that differs from the first position. Rotation by 90 ° or 180 °, 270 ° or 360 ° (or less than 360 °) can be particularly useful, i.e. the second orientation differs by 90 ° or 180 °, 270 ° or 360 ° or any angle in between . In particular, it can be provided that the shelf can be fixed in the first or second orientation. In principle, the second position can be defined in such a way that when the shelf is rotated, it is arranged in an inclined position with respect to the body, for example 100 °, 290 °, etc.

It can expediently be provided that at least one locking position is provided in at least one of the orientations of the shelf, in which the shelf can be releasably latched or releasably fixed. A particularly expedient fixing can consist of a latching which can be provided by means of a latching element. Such a latching element can be provided in each of the (two) fixable orientations in order to enable the shelf to be fixed in the corresponding position or orientation. A latching element can also be present if it is a receptacle for an area or a means of the shelf in which the area or the middle tel is set solvable. In particular, the latching element can have a guide slot which has a driver for the area or the means of the tray, wherein the driver can hold the means or the area, in particular in a latching position. To release the (latching) connection, it can be provided that an initial resistance has to be overcome or that the means or the area of the shelf has to be pushed further into the latching so that it can be released. For this purpose, the guide link can be designed with a corresponding path for releasing the area or the means. The area or the means can, for example, also be a hook that can be guided in the backdrop or that can be advanced.

The latching element can preferably provide a releasable connection with the shelf, whereby a simple change between the individual orientations of the shelf can be provided. For a connection with the latching element, an engagement means can be provided, which can be designed, for example, as a hook, a means or a region, and is provided to engage with the latching element in a manner that secures the deposit. In principle, any means is conceivable as an engagement means which can be fastened to the shelf and which can be releasably connected to the latching element to fix the position. The latching element can in particular be provided on the adjusting device, in the area of the rotating device, in particular in the area of the turntable or double turntable. In principle, the locking element can also be referred to as a locking device. This can be provided with the link guide in which the receiving means for a pin, tenon, bolt or some other element (means, hook, area, removable element) of the shelf is provided.

The receiving means can in particular be a guide element which, for. B. the pin, the pin, the bolt or other element receives, and which is movably mounted within the backdrop. The guide can be with a track be provided for the guide element, which can correspond approximately to the rotational movement of the shelf or the joint or the turntable or at least can follow this path. The guide element can also be operatively connected to a spring which can be relaxed or tensioned when the tray is rotated while the guide element is in operative connection with the pin, pin, bolt or other element of the receptacle (transmission element). Thus, by moving the shelf, the spring can be tensioned while the shelf is fed to a defined orientation in which the shelf or the guide element (driver) can be locked (see FIGS. 11 to 15). On the other hand, when the locking connection of the guide element is released, the spring force can be used to independently move the transmission element of the tray in the direction of a second defined orientation after the locking connection has been released. The transmission element can have a drivable element which can interact with the at least one guide element and can engage in it (FIGS. 11 to 15).

In this second orientation, a separate guide element with a further spring can in turn be provided, which can in turn interact in a spring-tensioning manner with the same transmission element of the shelf or a second transmission element of the shelf and can have a latching connection for securing the shelf in the second orientation.

It may be necessary, starting from a first alignment of the shelf to a (pivot) point / area in which one (first) spring is already relaxed, but the shelf is not yet locked in the second position, against the spring tension of the second spring to tension this and to feed the tray for example by hand to the second alignment. Between the relaxation of the first spring and the tensioning of the second spring, a range of rotation between the first or second orientation can be provided in which both springs are relaxed or are partially relaxed or neither the first nor the second spring can be changed in their state. In this area, the shelf can be freely rotatable about its axis independently of the link guide or guide elements.

It is particularly preferably provided that the stowage device has foldable side walls which can be lowered outwards. Furthermore, the cabinet according to the present invention can have at least one of the following properties, which can be freely combined with one another in any way.

- The body has a cuboid base body,

- the shelf has roughly the same shape as the body,

- the shelf is roughly the same width as the pull-out device,

- the first orientation is a starting position in which the shelf can be completely accommodated in the body,

- The second alignment can be provided rotated by at least 90 °, preferably 180 °, about the axis to the first alignment,

- the shearing mechanism has at least two shearing units that work together,

the shear mechanism has a support element which is in guided contact with at least one of the shear elements.

The present invention will be further described using preferred embodiments with reference to the accompanying drawings.

FIG. 14 shows the arrangement according to the invention according to FIG. 11 of two guide elements according to the invention on a swivel joint, the entrainment element 13 '"being delivered to the driver 31 ¹ and the driver 31' moving the entrainable element 13 '" in a spring-relaxing manner towards the second end position;

FIG. 15 shows a perspective illustration of a guide element according to the invention in an individual illustration.

Figure 1 shows a cabinet 10 according to the invention, on which a shelf 1 1 is mounted such that it can be pulled out and rotated. The tray 11 can have side walls 15, 16 which are arranged to be foldable in order to move them from an approximately vertical to an approximately horizontal orientation. In principle, all side walls of the tray 11 can have this function. Figure 2 shows an exploded view of the cabinet 10 according to the invention with an adjusting device for linear adjustment (pulling out) and horizontal rotation of the shelf 11. The adjusting device can have at least one, preferably two, guides 14, for example in the form of a linear extension, which are connected to a Swivel joint 13 can interact. The swivel joint 13 can also be designed with a turntable. A plate 12 or a rod on which the swivel joint 13 can be arranged can be provided as a connecting element between the swivel joint and the guide. In principle, the swivel joint can also be in direct contact with the guides 14. Compared to the adjustment device, in particular the guides 14 or the body 10 ′ of the cabinet 10, the shelf 11 can be rotatably mounted via the joint 13.

Figure 3 shows an even more detailed exploded view of the first embodiment of the present invention, which also shows that the shelf 11 can consist of a shelf as well as side walls 15 and 16, which can interact via corner elements 14 to border the shelf. In particular, joints can be provided in the corner elements 14, via which the side walls 15 and 16 can be mounted on the shelf so that they can pivot about a horizontal axis. As a result, they can be lowered in order to obtain easier access to the objects stored on the shelf 11. Instead of an inclination about an axis of rotation, it is also possible for the wall to be displaced, for example vertically downwards, in order to obtain easier access to the shelf 11. Appropriate guides can be provided for this. The plate 12 can be referred to as a platform and can be provided as a connection between the swivel joint 13 and the guides 14.

FIG. 4 shows a variant of the embodiment according to FIGS. 1 to 3, in which the platform 12 is designed as a cross linkage, at its intersection a receptacle 12 ′ for the swivel joint 13 can be provided. In principle, a constructive connection between the guide and the swivel joint can be provided. In Figure 4, the tray 11 is largely pulled out of the body 10 ', so that the tray 11 can be freely rotated relative to the body 10'. Such rotatability can be seen, for example, from FIG. 5, in which a front area 11 'of the shelf 11 faces the body opening, that is to say the shelf has been rotated through almost 180 ° or more than 180 °. The shelf can be so large that it cannot be freely rotated in the cabinet itself, but only becomes freely rotatable when it is pulled out of the cabinet via the guide.

As can be seen from FIG. 5, the side walls can in principle also be provided as individual struts which can form a railing around the shelf 11 via corner pillars.

FIG. 6 shows a further embodiment of the present invention which, instead of the classic guides 14, has a shear or cross mechanism 20 as a pull-out device, by means of which the tray 11 can be pulled out of the body 10 '. The mechanism 20 can be formed with at least one, preferably two, pairs of arms or (elongated) means. To support the mechanism and / or as a guide for the first pair of elongated means 15, 15 'relative to the body, a support arm 17 can be provided on which the first pair of (elongated) means 15, 15' can slide along. In an end region of the individual elongated means of the first pair of elongated means 15, 15 ', a second pair of (elongated) means 16, 16' can be connected, which can carry the swivel joint 13 individually or together. The individual (elongated) means of the two pairs can be directly or indirectly connected to one another in an articulated manner. The individual elongated means can also be referred to as shear members. As can be seen in particular from FIG. 8, the support arm 17 can have a guide part 17a. At least one of the two elongate means 15, 15 'can be guided along this guide part. At least one of the two elongate means 15, 15 'preferably also has a guide part 15a, 15a' which cooperates with the guide part 17a of the support arm. In this embodiment in particular, the support arm can also be referred to as a guide arm, with a supporting function not necessarily being provided. For the interaction of the individual guide parts 17a, 15a and / or 15a ', a connecting means, for example a bolt, can be provided which can slide along, in particular in / on / on, the individual guide parts. Thus, a guide area / a guide part can be formed, which can act as a joint at the same time. In particular, the guide parts of the two elongate means 15, 15 'can be limited in length, whereby a maximum extension of the drawer can be adjusted. When the connecting means has reached a front end region of a guide part in / on / on which it moves, an extension end position can be reached.

FIG. 9 shows the shear or cross arrangement according to FIG. 8 in a perspective view from below. From this it can be seen that the elongated means 15 'has reached an end region of the guide or support 17 and thus an end position of the tray 11 can be reached. In this, the shelf 11 can protrude so far from the body 10 'that the shelf 11 can rotate freely about the joint 13 or the axis of rotation of the joint. In this end position, the tray 1 1 preferably protrudes completely from the body 10 '.

Figure 10 shows the tray 11 on the above-described shear or cross mechanism in a rotated position in which a front part of the tray 11 protrudes to the rear. It is therefore possible to rotate the shelf 1 1 ready in which the respective corners of the shelf 11 can be guided past the side walls of the body 10 'without these making contact in a manner damaging the material. According to the invention, this can be prevented in the retracted state of the tray 11. These two embodiments are to be understood as an exemplary representation of possibilities of how the present invention can enable an adjustment device for linear displacement and rotation of a shelf about an axis. In principle, a door can be attached to the cabinet, which door can be closed in particular when the shelf 11 is located inside the body in the retracted position described.

FIG. 11 shows a preferred embodiment of the swivel joint 13, which can also be designed with a rotary plate. The swivel joint 13 can have a first area 13 ′ which can be fixed in relation to the mechanism 22 or the platform 12, that is to say in relation to a part that can be pulled out of the cabinet. For this purpose, recesses 35, for example in the form of bores, can be provided, via which the mechanism can be fixed in relation to the pull-out part of the cabinet. The swivel joint 13 can preferably be screwed or riveted to the extractable part via these recesses. Furthermore, the swivel joint 13 can have a second part 13 ″, which is mounted rotatably with respect to the pull-out part of the cabinet, preferably around a fixed axis of rotation. The rotatable mounting can in particular exist with respect to the first part 13 '. The rotatable second part 13 ″ can be provided with a drivable element 13 ′ ″, which can also be referred to as a pin or as a projecting means (in the direction of the axis of rotation). When the second part 13 ″ of the swivel joint 13 is rotated, the entrainable element 13 ′ ″ can also carry out the movement of the second part 13 ″, since it can be attached to it. A guide element 30, which can also interact with the removable element 13 ′ ″, can also be fixed in relation to the pull-out part of the cabinet. The guide element 30 can have a driver 31, for example in the form of a hook or a receptacle, which can be provided and arranged to interact with the entrainable element 13 '"or to receive it, preferably in a guiding manner. The interaction can in particular consist in that the entrainable element 13 ′ ″ is arranged in a receptacle of the driver 31 when the entrainable element 13 ′ ″ is provided in a suitable position relative to the guide element 30. Depending on which function the guide element 30 has, the entrainable element 13 '"can guide the driver 31 or the driver 31 can guide the entrainable element 13'". This relationship is explained further below.

The entrainable element 13 ″ can in particular be able to be advanced to the entrainment member 31 in an angular section of the rotation of the rotary joint 13 about its own axis. The driver 31 can interact with a spring 32 and / or a damper 33, the driver 31 being able to be supported so that it can be guided along a link / link guide 34. Against the spring force of the spring 32, the driver 31 can be moved along the link 34 into a first end region in which the driver 31 can be at least partially spaced approximately radially from the axis of rotation of the swivel joint 13. In particular in FIG. 11 on the right-hand side of the figure, this can be a lower end region of the link 34. In this position, the driver 31 can have a position in which the entrainable element 13 '"is at least partially released from the receptacle of the driver 31, whereby a rotation (clockwise) of the entrainable element 13'" (with the swivel joint) from a Contact area with the driver 31 is made possible. The link can be conformable to an outer contour of the joint 13, in particular a circumference of the joint.

This end position of the driver 31 is shown, for example, on the left side of FIG. 11 on the driver 31 '. In this position, the driver 31 is prepared for receiving the removable element 13 '". Through a contact of the entrainable element 13 '"with the driver in its first end position, as shown for the driver 31' in Figure 11, this can be moved / pushed out of the first end area (latching area) radially spaced from the axis of rotation of the swivel joint 13, whereby the spring tensioned in this position, which is not shown in detail on the left side (30 '), can be relaxed. The spring 32 guides the driver 31 through the link 34 approximately tangentially to the rotary joint 13, while the spring 32 relaxes at least partially. The damper 33 can be arranged opposite the direction of relaxation movement of the spring 32. As a result, the relaxation of the spring 32 and thus also the movement of the driver 31 is carried out in a damping manner, in particular along the link 34.

If a (second) end position in the link 34, a maximally retracted damping position of the damper 33 or a maximum relaxation of the spring 32 is reached, the driver 31 has reached its second end position in which it is at least partially brought closer to a rotation axis of the swivel joint 13, than in the first end position already described above.

The link 34 can approximately reproduce a circumferential shape of the rotary joint 13, in particular the shape of the outer circumference of the first part 13 ', or be embodied approximately tangentially to the rotary joint 13. Preferably, the alignment of the spring and / or damper is approximately parallel to one another and / or tangential to the rotary joint 13, in particular tangential to the point of the rotary joint 13 at which the driver 31 is fed to the rotary joint 13 so that it is connected to the entrainable element 13 '"is engaged.

By turning the upper cabinet clockwise from the position of the removable element 13 '"shown in FIG. 11, the driver 31 is removed from the device via the removable element 13'" (which also rotates by rotating the tray 11 through the swivel joint 13) position shown on the right in moves the radially spaced position against the spring force of the spring 32. This position is shown, for example, in FIG. 12, in which the driver has reached its at least partially radially spaced first end position and the removable element 13 ′ ″ leaves the receptacle of the driver 31 when the rotary joint is rotated clockwise. The first end region of the link 34 can be provided with a latching / bearing point or a latching / bearing receptacle in which the driver 31 can be positioned against the spring tension 32. A rotary movement of the rotary joint can thus be released by an approximately linear displacement of the driver.

Two guide elements 30 are preferably provided on the swivel joint 13 along the circumference of the swivel joint 13, preferably the first end points of the guide slot, in which the receptacle of the driver 31 is at least partially radially spaced from the drivable element 13 '", along the circumference of the swivel joint point to each other.

Figure 12 shows the two drivers 31 and 31 ¹ in their respective first end position. Due to their relative positioning along the outer circumference of the rotary joint 13, the entrainable element 13 ′ ″ can move between the two second end positions of the two drivers 31 and 31 ′ (along the circumference) of the rotary joint 13. Any further rotation can be restricted by the stop of the driver 31 or 31 'on the respective damper 33, 33' or a second end position 35 or 35 'along the respective link 34 or 34'. The driver 31 can accordingly be designed to release the entrainable part 13 ′ ″ from its receptacle only to one side, that is to say when the rotary joint is rotated either clockwise or counterclockwise. If, as in FIG. 11, the entrainable part 13 '"is provided on the right-hand side in the driver 31 in its second end position, the spring 32 is tensioned and the driver 31 in its clockwise direction by turning the swivel joint 13 or the tray 11 first end position of the backdrop relocated. Here, the entrainable element 13 ′ ″ guides the driver 31 into its first end position. If, however, the entrainable element 13 '"is fed to the driver 31 and the driver 31 is moved out of its first end position, the spring relaxes against the damping effect of the damper 33, and the driver 31 guides the entrainable element 13'" in the direction of its second End position. Whether the entrainable element 13 ′ ″ or the driver 31 determine the common movement along the link 34 therefore depends on the starting point of the driver 31 in the link 34.

The two guide elements 30 and 30 ‘can be provided at any desired angle to one another along the outer circumference of the joint 13. In Figure 11, they are aligned approximately at a 180 ° angle to each other. This also restricts the rotatability of the support 11 or the joint 13 to an angle of approximately 180 °. The restriction of the rotatability of the receptacle or the joint 13 can depend in particular on the angular position of the two drivers 31 and 3T in their two second end positions, as is shown, for example, in FIG. 11 on the right-hand side on the driver 31.

By relative positioning of the two drivers 31 and 31 ′ along an outer circumference of the joint 13, an angle of rotation of the rotary joint 13 or of the support 11, which is attached to the rotary joint 13, can be adjusted. The swivel joint can only rotate as far as the entrainable element 13 '"allows it to move between the two second end positions. For the functioning of the guide elements 30 in interaction with the removable element 13 '", it is fundamentally irrelevant whether the guide elements 30 and 30' are arranged on the shelf 11 and the removable element 13 '" is provided on a static part of the swivel joint 13 is or the other way around. In contrast, it can be decisive for the invention that the entrainable element 13 ′ ″ and the guide elements 30 and 30 ′ are attached to different parts of the swivel joint or to different parts of the pull-out unit. One of the parts (30, 30 ') / 13 should be arranged at least on a static area, i.e. a non-rotatable area, wherein the other part can be arranged on a rotatable part, for example the joint or the receptacle 11. The first end position along the link 34 is denoted by the reference number 36 in FIG.

In summary, it can be stated that the present invention relates both to this and to further embodiments of a drawer / shelf which can be pulled out of a cabinet body and is basically rotatably mounted.

It can preferably be provided that although the drawer / shelf can be freely rotated on a swivel joint, the free rotatability can be interrupted in certain positions due to an interaction of the swivel joint with means for positioning the rotatable part of the drawer / shelf, i.e. a Determination of the drawer / shelf in a certain position is enabled. This definition can be overcome or the drawer can be detached from the definition or fixed position.

The fixing can particularly preferably take place in a damped and / or guided manner, as a result of which vibrations, which can be attributed to the fixing, for example, can be reduced or avoided. In principle, it can be preferred that the drawer can either be moved back and forth between one or more fixations or is basically freely rotatable, i.e. rotatable through 360 °, the rotatability in the area of the fixation being interrupted to the extent that the fixation must be overcome.

FIG. 16 shows a further embodiment of the present invention which can basically function according to the same principle as the first embodiment.

The concept can be described in that a swivel joint 40 is provided on which a drawer / shelf, that is, a stowage option for a drawer, can be arranged. In relation to a base body of the pull-out drawer, the stowage facility can therefore be rotatable.

The base body can also be limited to a pull-out mechanism for the drawer / shelf.

The swivel joint can have a part 41 which can be fixed on the base body of the drawer and which is preferably fixed thereon.

Holding means 50, 51 are preferably provided which make it possible to fix the rotatable part, that is to say the attachment / tray, on the rotary joint in predefined rotational positions despite the free rotatability of the rotary joint.

For this purpose, a (resilient) receptacle, which can also be referred to as a shaped spring 50, can be provided on the swivel joint 40 or on a fixed (non-rotatable) part of the drawer. As a counterpart, a holding element 51 which can be reversibly fixed / engaging in the receptacle and which can also be referred to as an engaging element 51, for example a nose or a pin, can be provided accordingly on a fixed part of the drawer or the swivel joint. Thus, a first of the two parts (receptacle, holding element) can be provided on the swivel joint 40 and a second of the two parts on the base body or the fixed part of the drawer. A fixed part of the drawer can in particular be a non-rotating part or a stationary part of the extension of the drawer.

The receptacle, for example the shaped spring 50, can be designed, for example, as an open pretzel, as shown in FIG. In principle, the shaped spring 50 can have at least two functions. On the one hand, it can provide a receptacle 52 in which the engaging element 51 can be reversibly fixed, whereby the rotatable part of the drawer can be fixed in a (rotary) orientation which corresponds to an engagement of the engaging element in the receptacle of the shaped spring. When the engaging element is fixed in the receptacle of the shaped spring, the drawer can thereby be fixed in a rotational position.

A second function of the shaped spring can be to absorb the momentum of the rotatable part of the drawer before the engaging element 51 is fixed, that is to say to brake a rotary movement of the tray / drawer before it is fixed.

This can counteract damage to the shaped spring 50, since the rotatable part of the drawer / shelf does not have to first brake from the full speed of the rotary movement to 0 in the receptacle 52 of the shaped spring. For this purpose, a contact area 53 can be provided on the shaped spring which can be in contact with the engaging element 51 at least in some areas. This contacting 54 is evident, for example, from FIG. 17, in which the engaging element 51 is already in contact with the shaped spring 50, but is not yet arranged / fixed in the receptacle 52 of the shaped spring 50 (FIG. 16).

The contact area 53 of the shaped spring 20 to the engaging element 51 can be under spring tension in the contact state, which with increasing approach of the engaging element 51 can rise to the receptacle 52 on the shaped spring. For this purpose, the shaped spring can have a distance from a circular path of the element 51 around the swivel joint which decreases the closer (as a function of) the element 51 approaches the receptacle 52. A part of the spring can thereby experience a bending force starting from, that is to say through, the element 51, which can provide a braking sliding contact between element 51 and spring 20.

The rotational speed of the rotatable part of the drawer can thus be reduced by a type of sliding contact before the engaging element 51 reaches the receptacle 52 of the shaped spring 50. The shaped spring, which can also be referred to as the receiving element 50, can be formed symmetrically or asymmetrically. This shape can in particular extend along a circumferential path of the element 50. At least in the case of a symmetrical structure, the engaging element can be detachable from the receptacle 52 on both sides of the shaped spring, that is to say can execute a rotary movement on both sides of the shaped spring.

In principle, it may be possible, by applying a corresponding force to the rotatable part 40 of the rotary joint, to overcome the retaining force of the shaped spring 50, in particular its receptacle 52, and to release the engaging element from the receptacle 52 of the shaped spring 50.

This enables a further rotation of the rotary joint beyond the contact point / area between the receptacle 52 of the shaped spring 50 and the engaging element 51. In principle, a plurality of shaped springs 50 and / or engaging elements 51 can be provided on the rotatable part 40 of the swivel joint and / or the fixed part (that is, the non-rotating / static part) of the drawer. As a result, a plurality of (rotational) locking positions can be provided for the rotatable part of the drawer / receptacle on the adjustment device.

Referring to Figures 16 and 17, two engaging members 51 are disposed on the rotatable part 40 of the pivot joint on opposite sides thereof and a shaped spring 50 is provided on the fixed part of the drawer or the fixed part of the swivel joint 41 (which can be displaceably mounted via the adjusting device). In this way, the rotatable part of the drawer / receptacle can be fixed in two positions, with a rotation of 180 ° being possible between the positions.

The retention / retention force of the shaped spring 50 on the engaging element 51 in the engagement of the two shown in Figure 16 can be overcome by applying a corresponding force on the rotatable part of the swivel joint, preferably in both directions, resulting in a total rotation of 360 ° the drawer and beyond can be made possible.

The shaped spring 50 can also be referred to as a receiving element 50 for the reversible fixing of an engaging element 51 or area of the rotatable part 40 of the swivel joint for a drawer or support. The reversible fixing can take place from the receiving element 50 in both directions of rotation of the rotary joint.

For a particularly simple assembly of the swivel joint, it can be provided that a receptacle 60 for the swivel joint is provided on the fixed part of the drawer. This can be provided, for example, U-shaped or horseshoe-shaped, wherein the swivel joint with its fixed / to be fixed / non-rotating part 41 can be inserted, inserted or connected to a, preferably open, region of the receptacle.

To fix the swivel joint on the fixed part of the drawer, that is to say on the non-rotatably mounted part of the drawer, a fixing element, for example in the form of a hook, can be provided which holds the swivel joint in the receptacle 60. FIG. 18 shows the swivel joint and its receptacle 60 separated from one another, it being possible for guide rails 61 to be provided on the receptacle which can align the swivel joint, in particular the fixed part 41, in the exact position in the receptacle.

It is particularly preferred that the drawer can be held in an open position after it has been pulled out. For this purpose, corresponding FIGS. 19 and 20, a holding mechanism 80, 81 can be provided, which can be attached to a rear side of the drawer and to an inside of a body and, when the drawer is fully or as required, engage with one another (can be locked / locked) so that a certain compressive force has to be applied in order to release the drawer from the receptacle 80 of the holding mechanism so that it can be returned to the body. This compressive force can preferably be set greater than the compressive force which must be exerted on the rotatable part of a drawer in order to release the pivot joint / the engaging element of the rotatable part of the drawer from the receptacle 50, in which the drawer is fixed in an orientation of the rotary movement is. As a result, the drawer can be rotated via the above-mentioned locking points, e.g. in the form of the shaped springs 50, without the drawer being inadvertently moved back into the body.

The locking 80, 81 can in particular be designed as a latchable (FIG. 20) pair of hooks.

Alternatively, an actuatable area, a button or a lever can also be provided to release the holding mechanism 80, 81, which is in operative connection with the holding mechanism and can cancel the locking.

FIG. 21 shows a particularly preferred embodiment of the entire drawer which is shown in an exploded view and shows individual parts of such a drawer. In principle, each of these individual parts can be used without an additional part and in any combination thereof can be provided to practice the present invention.
