Description

The invention relates to a displacement device with a pair of scissors for a sliding door, optionally a folding sliding door, and a piece of furniture with at least one such displacement device, by means of which a sliding door, optionally a folding sliding door, can be displaced into a door compartment.

Sliding doors, optionally folding sliding doors, are often used to close off openings in pieces of furniture, which are pushed into a door compartment after the opening has been released, so as not to be a nuisance.

the US8336972B2 discloses a piece of furniture with a door compartment in which a displacement device is provided, by means of which the sliding door can be displaced within the door compartment. The displacement device comprises a pair of scissors, by which a stop profile connected to the sliding door is held in a vertical orientation. The scissor arms of the scissors cross can be rotated against each other so far that they are aligned parallel to each other in the end position of the sliding door and the scissors cross takes up little space and the sliding door can be retracted far into the door compartment. The displacement device also includes running rails, along which the stop profile can be slidably mounted in the door compartment by means of carriages.

the US9284761B2 discloses a piece of furniture with a displacement device by means of which a folding sliding door can be displaced into a door compartment. The folding sliding door comprises two door elements, of which the first door element is connected at the trailing edge by hinges to a stop profile, which is vertically aligned and held displaceably by a pair of scissors. The leading edge of the second door element, which is connected to the first door element by hinges, is connected to a carriage which can be displaced along a running rail which has two rail sections which are aligned perpendicularly to one another and are connected to one another by a curved section, one of which in the door compartment is led in.

In the case of the sliding devices mentioned, the sliding door is manually pushed into the door compartment and manually pulled out of the door compartment again. The manual movement of the sliding door requires a relatively large amount of force, which is why sliding devices are often equipped with drive devices.

the DE2045763A1 discloses a piece of furniture with a sliding device with a scissors cross whose scissor arms are connected to one another by a spring in order to automatically retract a sliding door held by the scissors cross into a door compartment.

If a sliding door is automatically ejected from a door compartment or automatically retracted into a door compartment by means of a mechanical drive device that has an energy store such as a spring or weight, the energy store must be manually recharged when the sliding door is pushed back into the starting position, which is why the effort required to manually push in or pull out the sliding door and load the drive mechanism is practically doubled.

Due to the considerable weight of the sliding door that is held, displacement devices of this type are also exposed to high forces, which is why undesirable noises may result during the actuation of the displacement device. Furthermore, signs of wear can occur after a longer period of operation.

The present invention is therefore based on the object of creating an improved sliding device with a pair of scissors and a piece of furniture with at least one improved sliding device with which a one-piece or multi-piece sliding door, optionally a folding sliding door, can be inserted into a door compartment.

The displacement device should allow the sliding door to be displaced between a rear stop and a front stop within a door compartment of a piece of furniture, manually or by means of a drive device, with as little effort as possible.

If the displacement device is provided with drive devices, these should be able to be operated reliably with energy stores of relatively small dimensions.

The displacement device, in particular the scissors device, should take up as little space as possible when folded. The scissor arms of the scissors cross should be able to be rotated in relation to one another to such an extent that they are aligned at least approximately parallel to one another in the end position of the sliding door.

The scissor arms should preferably be adjustable in such a way that they are aligned parallel to one another in the end position.

Disturbing noises and signs of wear should be avoided during operation of the displacement devices.

This object is achieved with a displacement device according to claim 1 and a piece of furniture with at least one such displacement device according to claim 12. Advantageous configurations of the invention are specified in further claims.

The displacement device is intended for a piece of furniture with wall elements that delimit a door compartment on one side of the piece of furniture or on both sides of the piece of furniture, into which a one-part or multi-part sliding door, optionally a folding sliding door, can be slid, which is slidably held by the displacement device.

The displacement device comprises a stop profile which is connected or can be connected to a one-part or multi-part sliding door by stop hinges and which is held in a vertical orientation by a scissors cross so that it can be displaced in a horizontal direction.

The scissors cross comprises a first scissors arm and a second scissors arm, which are rotatably connected to one another by a scissors bearing which defines an axis of rotation. The first scissor arm includes a first end piece rotatably and slidably supported in a first bearing device by a first bearing member and a second end piece rotatably supported in a third bearing device by a third bearing member. The second scissor arm includes a first end piece rotatably and slidably supported in a second bearing mechanism by a second bearing member and a second end piece rotatably supported in a fourth bearing mechanism by a fourth bearing member.

According to the invention, it is provided that the third bearing device or the fourth bearing device, preferably the third and the fourth bearing device, each have a bearing body with two bearing plates which are spaced apart from one another and between which the associated second end piece of the first scissor arm or the associated second end piece of the second scissor arm is rotatably supported by a bearing shaft. Furthermore, it is provided that the third and fourth bearing device are held at different distances from the axis of rotation and are arranged radially one above the other when the scissor arms are aligned parallel to the axis of rotation.

By mounting the second end piece of the first scissor arm and/or the second end piece of the second scissor arm between two bearing plates, forces acting on the scissor cross can be advantageously absorbed. Torsion of the scissor arms is largely avoided even under heavy loads. Friction losses are significantly reduced in the bearing devices, so that the sliding door that is held can be moved back and forth with reduced effort. Sliding doors that are operated purely manually result in increased comfort for the user with regard to the easily movable sliding door. If drive devices are used, they are less stressed and can be correspondingly smaller in size. When using mechanical drive devices, which only push the sliding door in one direction, there is a double advantage when the sliding door is returned manually: on the one hand, the scissors cross and, on the other hand, the appropriately dimensioned drive device only exert a reduced counteracting force, which occurs when the door is pushed in or pulled out Sliding door must be overcome.

Due to the reduction in the forces that occur in the bearing devices, noise emissions and signs of wear are also reduced. The scissors cross itself can therefore also be dimensioned more advantageously.

The arrangement of the third and fourth bearing device at different distances from the scissors axis allows the third and fourth bearing device to rotate against each other when the scissors cross is brought together or when the sliding door is driven in, without colliding with one another. Instead, when the scissor arms are aligned parallel to the axis of rotation, they lie radially one above the other. The scissor arms can therefore be moved completely towards one another and aligned parallel to one another, even with the largest dimensioning of the third and fourth bearing device. When the scissor arms are aligned in parallel, the third and fourth bearing devices are preferably in positive contact with one another with little play.

In a preferred embodiment, the second end piece of the first scissor arm and the second end piece of the second scissor arm have unequal lengths starting from the axis of rotation, which correspond to the distances between the third and fourth bearing device from the axis of rotation. The desired radial spacing of the third and fourth bearing device can therefore be achieved by appropriate dimensioning of the scissor arms.

In preferred configurations it is provided that the distances between the first bearing element and the third bearing element, which are held by the first scissor arm, are equal or unequal to the axis of rotation and/or that the distances between the second bearing element and the fourth bearing element, which are held by the second scissor arm , to the axis of rotation are equal or unequal. The scissor arms, on which the openings for the bearing elements are preferably provided in the same way, therefore preferably have unequal lengths.

The bearing elements are preferably designed as bearing shafts or bearing bolts. In preferred configurations, at least one of the bearing elements is mounted in the associated bearing opening without friction on one or both sides, for example by means of a rotary bearing, a roller, a roller bearing or a sliding bearing. In this way, friction losses are reduced to a minimum.

In further preferred configurations, it is provided that the third and/or the fourth bearing device preferably has vertically running longitudinal openings in the bearing plates of the associated bearing body, in which the associated third or fourth bearing element is preferably mounted so that it can be displaced vertically. In this way, optimal movements of the scissors cross are ensured. The third or fourth bearing element held in the longitudinal opening receives play parallel to the stop profile, by means of which blocking of the scissors cross is avoided, while the parallel guidance of the stop profile is further ensured. The longitudinal opening thus serves to ensure the necessary play and not to shift the bearing element over a greater distance when the scissor arms are rotated together. The third and the fourth bearing element of the third and fourth bearing device are therefore always kept at least approximately at the same level.

The first and the second bearing element, which are displaced over a greater distance when the scissor arms rotate, are preferably also mounted without friction. It is preferably provided that the first bearing element of the first bearing device is slidably mounted in a first bearing channel of a first bearing body of the first bearing device by means of a first bearing roller, and/or that the second bearing element of the second bearing device is mounted in a second bearing channel of a second bearing body by means of a second bearing roller the second storage device is slidably mounted.

So that the scissors cross can be correctly positioned within a door compartment and/or the stop profile can be precisely aligned vertically, at least one of the bearing devices is preferably adjustable or slidably mounted along a retaining rail and can be fixed in a suitable position.

If heavier sliding doors are connected to the stop profile, it is preferably provided that the stop profile is connected to an upper guide mechanism at an upper end piece, which is slidably mounted on an upper guide rail, and/or that the stop profile is connected to a lower guide mechanism at a lower end piece is connected, which is slidably mounted on a lower guide rail. The guide drives, which are preferably provided with running elements such as rollers or wheels, or sliding elements, are provided for guiding and possibly also for carrying or supporting the stop profile and relieve the scissors cross.

In preferred configurations of the sliding device or of the piece of furniture, the sliding door is a folding sliding door which has a first door element with a leading edge and a trailing edge and a second door element with a leading edge and a trailing edge, the first door element with its trailing edge the stop profile and its leading edge is connected to the trailing edge of the second door element by door hinges. A front carriage is preferably mounted on the leading edge of the second door element and is displaceable along a running rail which has a door compartment section which runs parallel to the guide rails and which is connected to a front section by a curved section. The runner can run along the front of the piece of furniture and into a door compartment on both sides.

The piece of furniture can be a cupboard or an arrangement, optionally a room arrangement with wall elements that delimit at least one door compartment. The door of the piece of furniture can be designed in one piece or have several door elements as a folding sliding door.

1 shows a piece of furniture according to the invention or a cupboard 1, in which a door compartment 10 is integrated on both sides. A folding sliding door 11 shown in the closed position can be slid into the first door compartment 10 by means of a displacement device 9 according to the invention, and a one-piece sliding door 11 held by a displacement device 9 according to the invention was pushed into the second door compartment 10 . The left folding sliding door 11 is completely pulled out of the door compartment 10 and completely unfolded, so that the door elements 111, 112 are aligned in one plane. Two thirds of the cabinet opening 100 are therefore covered by the left sliding door 11 .

1 further shows that the piece of furniture 1 has side walls 12, a top panel 14, a bottom panel 15 and partitions 13, each of which delimits one of the door compartments 10 with a side wall 12.

Like this too 2 shows, the trailing edge of the first door element 111 when the sliding door 11 is extended is connected by stop hinges 55 to a stop profile 5 which is vertically aligned and displaceable within the door compartment 10 . The leading edge of the first door panel 111 is connected by door hinges 119 to the trailing edge of the second door panel 112, the leading edge of which is connected to a front running gear 73 at the top. The front drive 3 is guided in a running rail 3 which has a front section 32 which runs along the front of the cabinet 1 and which is connected on both sides by curve sections 33 to door compartment sections 31 which run into the door compartments 10 .

The metal stop profile 5 is provided with a cross-sectional profile that allows the mentioned hinges 55 and bearing devices 62, 63 and drives 71, 72 to be installed in a simple manner and preferably to be held in a form-fitting manner, so that they can be fixed in a simple manner, for example by a grub screw be able.

By means of the bearing devices 62, 63, the stop profile 5 is connected to a scissors cross 4, which keeps the stop profile 5 vertically aligned and displaceable.

The scissor cross 4 from 2 , which e.g. also in Figure 4c 1 comprises a first scissor arm 41 and a second scissor arm 42 rotatably connected to each other by a scissor link 43 .

The first scissor arm 41 comprises a first end piece 411, which is rotatably and vertically displaceably held in a first bearing device 61 by a first bearing element 613, and a second end piece 412, which is rotatably held in a third bearing device 63 by a third bearing element 633. As is described below, the third bearing element 633 is also held in a displaceable manner in order to ensure that the scissors cross 4 can be opened and closed without resistance.

The second scissor arm 42 comprises a first end piece 421, which is rotatably and vertically displaceably held in a second bearing device 62 by a second bearing element 623, and a second end piece 422, which is rotatably held in a fourth bearing device 64 by a fourth bearing element 643.

The first and the fourth bearing device 61, 64 are connected to the piece of furniture 1, for example to the intermediate wall 13. The second and the third bearing device 62, 63 are connected to the stop profile 5.

When the scissors cross 4 is moved together or apart, the upper end pieces 411, 421 of the scissor arms 41, 42 can move vertically in this preferred embodiment of the displacement device 9, with the stop profile 5 always being held in a vertical orientation. The scissor cross 4 can also be turned through 180°, so that the lower end pieces of the scissor arms 41, 42 are held in a vertically displaceable manner.

In this preferred embodiment of the displacement device 9, the upper end piece of the stop profile 5 is also connected to an upper guide mechanism 71, which is slidably mounted on an upper guide rail 21. The lower end piece of the stop profile 5 is connected to a lower guide mechanism 72 which is movably mounted on a lower guide rail 22 . The guide rails 21, 22 are aligned parallel to one another and perpendicular to the stop profile 5 and are connected, for example, directly or indirectly to the top panel 14, the bottom panel 15, a side wall 12 and/or an intermediate wall 13. When the sliding door 11 is folded, the stop profile 5 can thus be pushed into the door compartment 10 up to a first stop and out of the door compartment 10 again up to a second stop. The first guiding carriage 71 can also fulfill a carrying function. The second guide carriage 72 can perform a support function.

The sliding door 11 can be moved into the door compartment 10 or moved out of the door compartment 10 manually or with support or automatically by at least one optional drive device 96 , 98 .

2 also shows damping devices 95 which are mounted within the door compartment 10, for example on a rear wall, intermediate wall 13 or side wall 12 of the cabinet 1 and which absorb the sliding door 11 in the rear end position.

3 FIG. 12 shows the part of the displacement device 9 from FIG 2 after the folding sliding door 11 has been fully pushed in, the first door element 111 of which has been cut open in order to reveal an optionally provided first drive device 96 on the upper side of the door compartment 10 and an optionally provided second drive device 98 on the underside of the door compartment 10. The first drive device 96 is arranged above the first guide rail 21 in a first bearing rail 216 . The second drive device 98 is arranged below the second guide rail 22 in a second bearing rail 228 . In addition to the first bearing rail 216, part of the running rail 3 is arranged in which the leading edge of the second Door element 112 arranged front drive 73 is held. The scissor cross 4 was dismantled.

The first drive device 96 has a first coupling element 961 which protrudes into the running area of a first coupling part 719 which is held by a carriage arm 718 or by the carriage body of the upper guide carriage 71 .

The second drive device 98, which has a second coupling element 981, is arranged on the underside of the lower guide rail 22 in such a way that the second coupling element 981 protrudes into the running area of a second coupling part 729, which is held by a carriage arm 728 or by the carriage body of the lower guide carriage 72 is.

When the upper guide carriage 71 is displaced, its first coupling part 719 is in contact with the first coupling element 961 of the first drive device 96 in a rear or distal displacement area of the door compartment 10. The lower guide carriage is in a subsequent front or proximal displacement area of the door compartment 10 72 with the second coupling part 729 in contact with the second coupling element 981 of the second drive device 98.

As soon as the first drive device 96 is unlocked and the upper guide carriage 71 is moved forward, the second coupling part 729 moves into the second coupling element 981 and is pushed forward by the second drive device 98, which was unlocked by the rotation of the coupling element 981, up to the front end stop pulled.

As soon as the sliding door 11 is pushed back into the door compartment 10, the second coupling element 981 is returned to the position shown and tilted in order to lock the second drive device 98 which has been loaded again. Preferably during the process of locking the second drive device 98, the first coupling part 719 comes back into contact with the first coupling element 961 and returns it to the position shown. In this process, the first drive device 96 is loaded and locked. This locking can be released again by pressing the sliding door 11 again, after which the sliding door 11 is moved back again by the unlocked first drive device 6 .

3 FIG. 12 further shows that the upper bearing rail 216 is connected to the running rail 3 and to an upper mounting rail 201. The upper guide rail 216 and the running rail 3 are form-fitting with one another coupled and aligned parallel to each other. The lower bearing rail 228 is connected to a lower mounting rail 202 at the lower side. When installing the displacement device 9, the mounting rails 201, 202 are preferably mounted first. The parts shown of the preferably configured displacement device 9 are arranged one above the other, so that they only take up little space inside the door compartment 10 between the folded door elements 111, 112.

Figure 4a shows the displacement device 9 with the cross scissors 4 of 2 , which has two scissor arms 41, 42 rotatably connected to one another by a scissor bearing 43, which is connected to the piece of furniture 1 by first and fourth bearing devices 61, 64 and to the stop profile 5 by second and third bearing devices 62, 63. The scissors cross 4 was related to 2 already described in the introduction. The first storage device 61 and the fourth storage device 64 are mounted, for example, on a side wall 12 or intermediate wall 13 of the cabinet 1 or possibly of a building that has a door compartment 10 for receiving a sliding door 11 . The second and the third bearing device 62, 63 are connected to the stop profile 5, on which stop hinges 55 can also be mounted, which are connected to the trailing edge of the sliding door 11 or a door element 111.

Figure 4b shows the displacement device 9 of FIG Figure 4a with the scissor arms 41, 42 of the scissor cross 4, which are almost completely turned against each other. The scissor cross 4 is in Figure 4b , 7a , 8a and 8b shown in this rotational position of the scissor arms 41, 42 so that they are individually visible and the device parts do not overlap constantly. The scissor arms 41, 42, on the other hand, can be rotated further until they are aligned parallel to one another.

Figure 4c shows a front view of the displacement device 9 of FIG Figure 4a with the scissor arms 41, 42 rotated apart. The distance R63 from the third bearing device 63 or from the third bearing element 633 to the axis of rotation x and the distance R64 from the fourth bearing device 64 or from the fourth bearing element 643 to the axis of rotation x or to the scissor-type bearing 43 drawn. Furthermore, the radial difference D63-64 between these distances R63, R64 is shown, corresponding to which the third bearing device 63 and the fourth bearing device 64 are superimposed radially when the scissor arms 41, 42 are twisted together, as is shown in Figure 4b is shown. The selection of the distances R63, R64 thus ensures that the scissors cross 4 can be rotated completely, even if the third and fourth Bearing device 63, 64 are larger in size and are provided for supporting the associated second end pieces 412, 422 of the two scissor arms 41, 42 on both sides.

Concentric circular segments (shown in dot-dashed lines) show that the distance R61 of the first bearing device 61 from the axis of rotation x corresponds to the distance R63 of the third bearing device 63 from the axis of rotation x, and that the distance R62 of the second bearing device 62 from the axis of rotation x corresponds to the distance R64 of the fourth bearing device 64 corresponds to the axis of rotation x. In this preferred embodiment, the difference between the length L41 of the first scissor arm 41 and the length of the second scissor arm L42 therefore corresponds to twice the radial difference D63-64.
