Description

The present invention relates to a furniture element, in particular to a shelf or rack, according to the restrictive part of paragraph 1 of the claims.

Furniture elements, such as, in particular, shelves or racks in which a support plate and a shelf guided on it are located and are at the same time rotatable and translational, are known, for example, from JP 10318669 or DE 10 2017 106 170 A1.

In particular, the support plate described in the second publication has proven itself in practice.

To move a shelf that is open there, you must pull on the side wall or the handle attached to it to rotate and slide out the shelf.

It is an object of the present invention to further develop a furniture element, such as a shelf or rack, in such a way as to further simplify the operation of moving the shelf from a resting position to an unloading position or the opening movement of a rack closed by side walls in a resting position to a position in which the shelves of the rack are accessible to the user .

This problem is solved with the help of a furniture element having the characteristics of paragraph 1 of the formula.

The furniture element according to the invention, in particular in the form of a base or a shelf having at least one level of tiers, has a frame or shelf and a bottom panel.

The base in this case refers to pallet floors, turntables and shelves in household appliances.

The supporting surfaces of the frame and the bottom panel facing each other each have at least one running groove in which the rolling elements are guided.

The frame can be moved relative to the bottom panel from its original position to an intermediate position, then to the open position and back.

In the intermediate position, the housing rotates relative to the bottom plate in one direction of rotation and is displaced in a given direction.

An opening and/or closing mechanism with a power battery supporting the opening and/or closing movement of the frame is located on the surface of the bottom panel facing away from the frame.

Such a furniture element is characterized by an easily activated opening, where only a slight pressure is required on the frame of the furniture element to move the frame from its original position, supported by the power of the power battery, to the open position.

Preferred embodiments of the invention are the subject of the dependent claims.

According to a preferred embodiment, the mechanism is located on the surface of the bottom panel facing away from the frame.

According to a preferred further development of the invention, a guide channel is provided in the bottom panel, which defines the direction in which the guide element is displaceably mounted, the mechanism being connected to the guide element.

In addition, the power battery is attached to the bottom panel and connected to the guide member to maintain the sliding movement in the guide channel.

As a result, all the mechanics of the mechanism are mounted under the bottom panel, invisible to the observer.

According to a preferred further development, the mechanism includes a pin protruding from a surface of the bottom panel remote from the frame, and a control disk rotatably mounted on the guide member and having a plurality of control elements for controlling the movement of the control disk relative to the pin.

The pin and the control disk controlled by it provide structurally simple and reliable control of the opening of the frame of the furniture element.

According to another preferred development, the control disk is designed as an annular disk having a central hole surrounding the guide element. The control elements are located, in particular formed, on an annular surface facing the lower panel.

The first control elements are preferably made in the form of circular gripping elements located at the same angular distance from each other, with a recess open to the center of the control disk.

This allows, in particular, to fix the frame both in the initial and in a predetermined open position.

The second control element is preferably made in the form of a toothed ring located between the first control elements and the central hole, with teeth located at the same angular distance from each other and directed towards the first control elements.

The teeth and the imaginary central perpendicular of the recesses of the first control elements are aligned in an angular range of 60 to 120°, particularly preferably at approximately right angles to each other.

This allows the control disk to be controlled in an uncomplicated manner, so that the release of the control disk from the pin, caused by pressing the frame from its original position against the opening direction, is accompanied by a slight rotational movement of the control disk.

After subsequent release of the frame, the frame can be opened by means of the power accumulator, wherein a pin passes between two adjacent first control elements, allowing the frame to move further in the opening direction.

According to a preferred embodiment of the invention, the power battery is made in the form of a torsion spring.

Such torsion springs can be inexpensively manufactured and installed on a furniture element.

According to a preferred further development, the power battery, which is designed as a torsion spring, is fixed at its first end in a drilled hole on the surface of the bottom panel facing away from the frame.

This allows the power battery to be installed on the bottom panel in a simple and cost-effective manner.

According to another preferred development, the power accumulator, which is designed as a torsion spring, is fixed at its second end in a drilled hole on the surface of the guide element facing away from the frame.

To avoid an unwanted increase in the height of the furniture element, the surface of the bottom panel facing away from the frame has a cutout into which the mechanism is inserted.

According to a preferred embodiment, the guide element is part of a locking device for vertically securing the bottom panel to the frame of the furniture element, which results in a reduction in the number of required components of the furniture element.

According to another alternative embodiment of the invention, a guide channel is provided in the bottom panel, which defines the direction, and in which the guide carriage is movably mounted. Such a guide carriage serves in particular to further stabilize and further improve the running smoothness of such a rotatable furniture element.

The displaceable installation of such a guide carriage in the guide channel of the bottom panel is also possible in principle without a mechanism for opening or closing the frame with a power battery supporting the opening and/or closing movement of the frame.

In an alternative embodiment, this mechanism for opening and/or closing the frame with a power battery supporting the opening and/or closing movement of the frame is in the form of an ejector or a push and move mechanism with a plunger associated with the power battery with which to push the guide carriage from the initial position along the guide channel.

The use of such a pushing and moving mechanism makes it possible, in particular, to construct a furniture element without an actuator handle and to initiate the opening movement of the furniture element by pushing it against the intended opening direction. It is also possible to use an ejection mechanism that can be operated in another way.

According to another preferred embodiment, the guide carriage is formed as part of a fixing device for vertically securing the bottom panel to the frame.

According to a preferred further development, this locking device has a roller bearing located on the underside of the guide carriage facing away from the frame, with at least two rollers arranged one behind the other in the longitudinal direction of the guide channel.

The rollers have circumferential V-shaped grooves into which V-shaped bridges project from opposite side walls of the guide channel, and these V-shaped bridges form the rolling surfaces for the rollers.

The interaction of these successive rollers with V-shaped bridges ensures, on the one hand, reliable vertical fastening of the guide carriage.

In addition, the support width of this translational-rotating mechanism is further increased by a plurality of rollers arranged one behind the other, so that reliable guidance is ensured even when using heavier furniture elements, in particular in the weight range of more than 50 kg, without causing the furniture element to tilt .

According to a further preferred embodiment, a bearing journal projecting into the hole in the support panel is formed integrally on the upper side of the guide carriage facing the frame of the furniture element for rotating the support panel and thus the frame of the furniture element relative to the bottom panel, in this case, the rolling bearing ring inserted into the hole is put on the bearing journal.

According to another preferred embodiment, a stop is located on one end surface of the guide carriage, which abuts the plunger of the ejector or push-and-pull mechanism as the guide carriage approaches.

This embodiment of the guide carriage makes it possible to dispense with a small number of bearing components.

In the following description of the figures, terms such as “top”, “bottom”, “left”, “right”, “front”, “rear”, etc., refer solely to the approximate design and location of the furniture element, frame, bottom panel, guide member, pin, control disk, control member, etc., selected from the respective figures. These terms are not to be understood in a restrictive manner, and these instructions may change for other operating positions, mirror symmetrical designs, etc.

In fig. 1-4, the first variant of the furniture element according to the invention is designated by position number 1. The furniture element 1 here is made in the form of a rack having a frame 3 with a square base and three storage compartments with corresponding shelves 33 and two side walls 32 covering the frame 3 from the side.

The furniture element 1 also has a bottom panel 2 located on the frame 3.

The supporting surfaces 21, 31 of the frame 3 and the bottom panel 2, facing each other, have corresponding running grooves 22, 62, into which the rolling elements 51 are guided, which serve to support the frame 3 with the possibility of translational and rotational movement relative to the bottom panel 2.

In fig. 5 shows an alternative embodiment of a furniture element 1 according to the invention, in which the frame is made in the form of a shelf having a support surface 31, which, together with a lower panel 2, which is not visible here, can perform rotational and translational movement relative to the lower panel 2 in a similar way using corresponding rolling elements guided in running grooves, which are not shown here.

The operation of the corresponding furniture element is described, for example, in DE 10 2017 106 170 A1 or DE 10 2018 108 977 A1, which have not yet been published.

This furniture element may also preferably be provided with an opening and/or closing mechanism, described below.

As shown in FIG. 4, it is also possible to form the running grooves 62 of the frame 3 in a separate support panel 61 attached to the underside of the first flange 31.

As shown in FIG. 4, the rolling elements 51 are preferably installed in a rolling element frame 5, which in the embodiment shown here is made in the form of a square-shaped frame corresponding to the base area of the furniture element 1, having a total of eight rolling elements 51 installed therein, preferably in the form of balls.

In this case, the bottom panel 2 together with the rolling elements 51, the rolling element frame 5 and the support panel 61 or running grooves 62, if provided on the lower side of the first flange 31, together form a translational-rotational bearing 6.

With such a translational-rotary bearing 6, the frame 3 can be offset relative to the bottom panel 2, for example, from the corner of the room 4 in the direction A and, essentially, simultaneously rotated about the rotation axis of a variable position from the initial position shown in FIG. 1, in the direction of rotation R ₁ through the intermediate position shown in FIG. 2 to the open position shown in FIG. 3.

In this case, the proportions of translation and rotation in the overall movement may change during the movement.

To enable translational movement, the bottom panel 2 contains a guide channel 23, which specifies the direction A of the translational movement and in which a guide element 71 is movably installed.

The guide element 71 is preferably part of a fixing device 7 for vertically fastening the bottom panel 2 to the frame 3 of the furniture element 1.

In addition to the guide member 71, which is rotatably and movably held in the guide channel 23, the locking device 7 has a screw 72, which is secured to the underside of the bottom flange 31 and, in the case of the support panel 61, located between the bottom panel 2 and the frame 3 , is screwed through the central hole 63 of this support panel 61 into a screw hole provided for this purpose on the upper side of the guide element 71 facing the frame 3.

The guide channel 23 runs approximately diagonally on the surface of the bottom panel 2, which allows the frame 3 of the furniture element 1 to be pulled out from the corner of the room 4.

In this context, it is, of course, also possible to use a fully rotatable slewing bearing 6 structure with a guide channel 23 running, for example, parallel to the side edge of the bottom panel 2, whereby the frame 3 of the furniture element 1 can be moved forward from the rear wall, for example perpendicular to the back wall, and at the same time rotated.

As shown in FIG. 6, an opening and/or closing mechanism associated with a guide member 71 is located on the surface of the bottom panel 2 facing away from the frame 3, with a power battery 9 supporting the opening and/or closing movement of the frame 3.

In the preferred embodiment shown here, the mechanism is designed as a so-called Push-to-move mechanism, by means of which, by gently pressing the front surface or side wall 32 of the frame 3, the mechanism is released from the basic position shown in FIG. 1, and after subsequent release of the frame 3, the furniture element 1, driven by the power battery 9, can be moved from the original position shown in FIG. 1 to the intermediate position shown in FIG. 2.

In addition to the power battery 9, which is attached to the bottom panel 2 and is preferably in the form of a torsion spring, the mechanism includes a pin 10, which protrudes from the surface of the bottom panel 2 facing away from the frame 3, and a control disk 8, which is rotatably mounted on the guide element 71 and has a plurality of control elements 82, 83 for controlling the movement of the control disk 8 relative to the pin 10.

In addition to the embodiment of the power battery 9 in the form of a torsion spring, as shown in FIG. 6-20, other embodiments of the power battery 9 are also possible.

The power battery 9, shown in Fig.6-20, made in the form of a torsion spring with a first section 91 and a second section 92, bent at an angle relative to the first section 91, is fixed, in particular inserted, by the first end 93, which forms the end of the first section 91 , in the drilled hole 26 on the underside of the bottom panel 2, facing away from the frame 3.

The part of the first section 91 of the torsion spring 9 immediately adjacent to this first end is placed under the counter jumper 27 extending from the bottom panel frame 25 into the bottom panel cutout 24, such that the first end 93 of the power battery cannot move out of its position. , inserted into the drilled hole 26.

The counter web 27 is preferably thinner at its free end 28 than the base of the counter web 27, which is close to the frame 25.

The cutout 24 serves to accommodate the mechanism, which is thus discreetly housed in the bottom panel 2 and protected from dirt. The result is a small overall height of the bottom panel 2.

The power battery 9, made in the form of a torsion spring, is fixed with a second end 94, forming the end of the second section 92, in a drilled hole 73 on the surface of the guide element 71, facing away from the frame 3.

As shown in Fig.6-20, the control disk 8 is made in the form of a ring 81 with a central hole 84 covering the guide element 71.

The control elements 82, 83 are located on an annular surface facing the bottom panel 2, and in the preferred embodiment shown here are integral with the latter.

The first control elements 82 are made in the form of circular gripping elements located at the same angular distance from each other, with a recess 85 open towards the center of the control disk 8, adjacent to the two legs of the corresponding first control element 82.

The imaginary central perpendicular of the recess 85 is not radially aligned with the center of the hole 84, but is at an angle thereto.

The second control element 83, as shown in FIG. 6-20, is a toothed ring located between the first control element 82 and the central hole 84, with teeth 86 located at the same angular distance from each other and directed towards the first control elements 82.

The teeth 86 and the imaginary central perpendicular of the recesses 85 of the first control elements 82 are preferably aligned in an angular range of 60 to 120°, in particular approximately perpendicular to each other.

It is also possible to attach legs (not shown) to the surface of the bottom panel 2 facing away from the frame 3, especially if the bottom panel does not have the cutout 24 shown in FIG. 6 to accommodate the opening mechanism.

Fig. 7-20 further disclose an exemplary process for opening a furniture element 1 configured as a shelving unit.

In this regard, in FIG. 7 shows the initial position of the frame 3 of the furniture element 1 shown in FIG. 1. As shown here, the control disk 8 is positioned such that one of the first control elements 82 receives the pin 10 in its recess 85.

Due to the connection of the control disk 8 with the guide element 71, the translational movement of the guide element 71 together with the frame 3 in direction A, shown in FIG. 2, and is blocked.

In the position shown in FIG. 8, the user lightly presses the frame 3 in a direction opposite to the direction A. At the same time, the frame 3 is pressed in the opposite direction.

In this case, the guide element 71 is pressed together with the control disk 8 in a direction opposite to the direction A, so that one first control element 82 moves away from the pin 10, so that in this position the pin 10 is located between the first control element 82 and the second control element 83 , made in the form of a gear ring.

When the frame 3 is pressed further into the switching limit position shown in FIG. 9, the second control element 83 is pressed into engagement with the pin 10 so that the pin 10 is located between the two teeth 86 of the second control element 83. In this way, further pressing on the frame 3 is prevented.

The power battery 9, made in the form of a torsion spring, is in the maximum voltage position.

Then the user can release the frame 3. As a result of releasing the user's pressure, the power accumulator 9 acts as a torsion spring and presses the guide element 71 together with the control disk 8 along the guide channel 23 in direction A. This causes the frame 3 to move into the intermediate the position shown in Fig. 2.

During this process, the side edge of one of the first control elements 82 abuts the pin 10, causing the control disk 8 to rotate slightly.

The first control element 82 slides on the pin 10 during further movement, with a slight rotation of the control disk 8, as shown in Figs. 10 and 11.

After passing the first control element 82, the pin 10 is disconnected from the mechanism, thereby freeing the frame for translational and rotational movement to the intermediate position shown in FIG. 2.

The unlocking position is shown in Fig. 12.

In fig. 13 shows the position of the bottom panel 2 in an intermediate position of the frame 3 shown in FIG. 2. The power battery 9, made in the form of a torsion spring, is in the maximum voltage position.

In order to fully open the frame 3 from the intermediate position shown in FIG. 2 to the open position shown in FIG. 3, the translational-rotational movement of the frame 3 is first performed again until the pin 10 passes the intermediate position shown in FIG. 14, in which the pin 10 is still not engaged with the mechanism, to the position shown in FIG. 15.

In this process, the outer edge of one of the first control elements 82 abuts the pin 10, causing the control disk 8 to rotate or align.

In the image from FIG. 16, the frame 3 and the control disk are in a position in which the pin 10 can slide between two adjacent first control elements 82 in a direction opposite to the direction A.

In this position, the power battery 9 is unloaded, so that to further move the frame 3 to the open position, the user must again press the frame 3 against direction A.

When the frame 3 is pressed against the direction A, the pin 10 again falls between the two teeth 86 of the second control element 83 when the control disk 8 is pushed further, as shown in FIG. 17.

The user feels this by the fact that with additional pressure there is no further movement of the frame, due to its blocking by the contact of the pin 10 with the second control element 83.

If the user then releases the frame, this release of pressure in turn activates the power accumulator 9, which presses the frame 3 together with the guide member 71 and control disk 8 in direction A, as shown in FIG. 18.

As shown in FIG. 19, the pin 10 rests against the inner side of the leg of one of the first control elements 82, forming a recess 85.

In this process, the control disk 8 rotates until the pin 10 is completely seated in the recess 85 of one of the first control elements 82, as shown in FIG. 20. In this position, the frame 3 is now completely open, allowing easy access to the shelves 33.

If the frame 3 needs to be moved back to the closed position, the above described movement sequence is carried out in the same order.

Accordingly, in order to start moving the frame 3 to the closed position, the frame 3 is unlocked by pressing.

This ensures that the frame 3 cannot move out of its end positions without manual intervention and is maintained in the open or closed position during movement.

Alternatively, the mechanism can be configured to have, optionally, only one lock in one end position and only one support during the opening or closing movement.

In fig. 21-30, an alternative embodiment for translational-rotational mounting of furniture element 110 is disclosed.

As shown in FIG. 21 and 22, the bottom panel 120 also has running grooves 122 on its support surface 121 facing the support panel 161 for guiding the rolling elements 151, here in the form of balls. The running grooves 162 of the support panel 161 are not shown.

The rolling elements 151 are also placed in the rolling element cage 150 to prevent loss. Unlike the embodiment shown in FIG. 4, the rolling element cage 150 here has a circular shape with several projections extending radially outward.

There is also a guide channel 123 provided centrally and diagonally to the two side edges of the bottom plate 120, which are aligned at right angles to each other.

The guide carriage 171 is movably mounted in this guide channel 123.

The guide carriage 171, as part of the locking device 170, has on its upper side facing the support panel 161 or the frame 130 of the furniture element 110 a bearing journal 172 projecting into a hole 163 in the support panel 161, which is preferably formed integrally with the upper part carriage guide 171.

This bearing journal 172 serves as an axis for a rolling bearing ring 177 inserted into the hole 163 of the support panel 161, in particular a ball bearing ring, by which a simple rotational movement of the support panel 161 relative to the guide carriage is effected. 171 and therefore relative to the bottom panel 120.

On the lower side of the guide carriage 171, facing away from the support panel 161, there is a roller bearing having at least two rollers 174 arranged, in particular, fixed one behind the other in the longitudinal direction of the guide channel 123.

Each of these rollers 174 has a circular V-shaped groove 175 into which V-shaped bridges 124 protrude from opposite side walls of the guide channel 123 to form running surfaces for the rollers 174.

The V-shaped grooves 175 of the rollers 174, which are guided along the V-shaped bridges 124 in the guide channel 123, provide an extremely stable and constant sequence of translational and rotational movement of the furniture element 110. The locking device 170 is protected from unintentional loosening at the top and bottom in each case by the locking element , in particular with a removable locking pin 176, 178. This makes it possible to easily assemble and disassemble the furniture element.

In this embodiment, the translational-rotating installation is also preferably configured such that the guide carriage 171, similar to the guide member 71, moves from a home position in which the furniture frame 130 is in its home position relative to the stationary part of the furniture piece 100 during the opening movement, moves along the guide channel 123 to the opposite ends of the guide channel 123 and moves from the opposite end of the guide channel 123 back to the original position to achieve the open position.

As shown in FIGS. 21 and 25-27, as an alternative to the mechanism shown in FIGS. 6-20 to open and/or close the frame 3 with the help of the power battery 9 facilitating the opening and/or closing movement of the frame 3, an ejector or pushing and moving mechanism 140 with a plunger 142 connected to the power battery 141 is used in the bottom panel 120.

By means of this ejector or push-and-travel mechanism 140, the guide carriage 171 can be ejected from its resting or open position along the guide channel 123 upon activation, thereby initiating the translational and rotational movement of the support panel 161 and thus the furniture element 110.

As shown in FIGS. 25-27, the pushing and moving mechanism 140 is located on the underside of the bottom panel 120 facing away from the support panel 161 in a receiving groove 127 provided for this purpose, which is here fixed in position in the receiving groove 127 by a retaining member. 143, made in the form of a plate.

The plunger 142 thus projects into the guide channel 123, as shown in FIG. 26 and 27.

As a result, upon approaching the guide carriage 171, the plunger 142 can be pressed against the force of the power battery 141, for example, in the form of a compression spring, into the housing housing the power battery 141, and pressed into the latching position by means of a latching mechanism known in the art. .

To operate the push and move mechanism 140, the plunger 142 must be pushed further into the housing from the position shown in FIG. 25, against the pushing direction, which is accomplished by pressing the frame of the furniture element 110 against the body against the pushing direction of the pushing and moving mechanism 140.

When the push and move mechanism 140 is actuated, the guide carriage 171 is pushed along the guide channel 123, thereby causing the frame 130 of the furniture element 110 to open.

In this case, the plunger 142 interacts with the guide carriage 171 in such a way that not only the opening movement of the frame 130 of the furniture element 110 from the original position is supported, but also the closing movement of the frame 130 of the furniture element 110, that is, both directions of movement are supported by only one ejector or mechanism 140 pushing and moving.

This initial position is shown as an example in Fig. 28. In this position, the frame 130 of the furniture item 110 is positioned in the furniture item 100 such that the outer walls of the frame 130, together with the outer walls of the fixed portion of the furniture item 100, cover the outside of the furniture item.

In the open position shown as an example in FIG. 30, the frame 130 of the furniture item 110 is located in the furniture item 100 such that the two outer walls of the frame 130 are located immediately in front of the outer walls of the stationary portion of the furniture item 100 and are accessible from the outside from areas of the furniture item covered by the outer walls.

As in the starting position shown in FIG. 28 and in the open position shown in FIG. 30, the guide carriage 171 is in the position shown in FIG. 25, as explained above.

According to another preferred embodiment, there is a stop 173 that is located on one end surface of the guide carriage 171 to push the guide carriage 171. When the guide carriage 171 approaches the ejector plunger 142 or the push and move mechanism 140, the stop 173 abuts the plunger 142.

To illustrate the movement of the furniture element 110, FIG. 23 and 24 show a bottom panel 120 supported by a furniture base 101 on which a support panel 161 attached to the underside of the frame 130 of the furniture item 110 is slidably and rotatably mounted. Here in fig. 23 shows a starting position corresponding to placing the furniture elements 110 in the starting position shown in FIG. 28.

In fig. 24 shows the position of the support panel 161 rotated approximately 65° relative to the base 101 and bottom panel 120.

In fig. 25 shows the starting position shown in FIG. 23, on the underside of the bottom panel 120 and the support panel 161, in which the guide carriage 171 is almost completely pressed into the ejector plunger 142 or the push and move mechanism 140.

In fig. 26 shows the position of the support panel 161 rotated by 5° relative to the bottom panel 120 in perspective corresponding to FIG. 25. In this position, the support panel 161 is progressively displaced by the distance of movement of the plunger 142 from the original position.
