    15 20 25 30 2 for example plates of a larger model on a shelf inside the cabinet. Alternatively, the entire existing cabinet can be replaced with a new one which is located a distance from the wall behind the cabinet. This means increased costs in connection with the installation of height-adjustable cabinets.
    Thus, there is a need for better diagonally height-adjustable cabinet fittings that at least partially solve the problems above.
    SUMMARY OF THE INVENTION An object of the invention is to at least partially eliminate the above problems by realizing that stabilizing the conductor arms of the cabinet interior in an area where instability usually occurs allows the cabinet interior to be fully retracted relative to the wall behind the cabinet interior without become unstable. The object of the invention is achieved according to an aspect of the invention by a stabilizing device for a height-adjustable cabinet device provided with at least two articulated arms, which stabilizing device comprises a guide part and a coupling part, which start from a mounting portion, the stabilizing device being arranged to be pivotally mounted at a hinge point on its mounting portion around a point on a first hinge arm of the cabinet interior, said coupling part being arranged to cooperate with a coupling unit on a second hinge arm of said cabinet housing when said hinge arms are moved from a first position to a second position, the guide part cooperating with a control unit on a wall bracket for a cabinet device for controlling the movement of the stabilizing device when said conductor arm is moved from the first position to the second position.
    A stabilizing device as above means that the guide arms are prevented from moving in an undesirable manner relative to each other, i.e. outside a desired path. This is done by the coupling unit cooperating with the coupling part and by the control part cooperating with the control unit. The interaction of the guide part with the control unit also to some extent prevents the guide arms from moving in an undesired manner in relation to a wall in which the wall bracket is attached. The desired trajectory of the guide arms means that the guide arms are substantially parallel. In this way, the cabinet interior is stabilized when the conductor arms are in such a way that instability usually occurs in cabinet cabinets of known technology, i.e. the cabinet cabinet is in a position which is located in the area which is so close to a rear wall behind the cabinet interior that the cabinet interior becomes unstable. Such a position is in an area where the guide arms have passed a breaking point in which the angle between the longitudinal extent of the second guide arm and the longitudinal extent of the side piece is large enough so that the parallel relationship of the guide arms can be influenced. Stabilization of the cabinet interior means that the side pieces of the cabinet interior are prevented from moving non-parallel relative to the wall because the conductor arms are prevented from moving non-parallel.
    The coupling unit on the first articulated arm may be part of the articulated arm or a free-standing part attached to the articulated arm. The control unit can be a part of the stabilizing device, a part of the wall bracket or a free-standing part.
    The coupling part can be designed as a projection, for example in the form of a rotatable roller which is adapted to be received by the coupling part, which in that case may comprise a groove. Alternatively, the coupling part may be in the form of two elongate parallel projections which together form a groove which can receive a shaped projection arranged on the coupling part, such as a rotatable roller.
    The guide part may comprise a projection, such as a rotatable roller which is arranged to be guided against a guide unit in the form of a rail or a groove.
    Alternatively, the control unit may be formed as a projection, such as a rotatable roller, and the control part may comprise a rail or a groove, the control unit being arranged to be guided along the control unit.
    The first position and the second position may both be any position in the area where the conductor arms of prior art cabinet fittings are usually unstable or one of the positions may be in the area where instability usually occurs and the other within the usually stable area of the conductor arms. in cabinet fittings of known technology.
    According to an exemplary embodiment, said coupling part comprises a recess.
    By means of a recess in the coupling part, a projection on the guide arm can easily be forced into a predetermined path. According to an exemplary embodiment, the conductor arms are prevented from moving in an undesired manner by the coupling unit on the first conductor arm following the recess of said coupling part.
    The coupling unit can be a part of the stabilizing device according to the invention which is arranged to be mounted on said second guide arm, a part of the guide arm or a free-standing part.
    According to an exemplary embodiment, the control part comprises a projection which is intended to cooperate with the control unit when said guide arms are moved from a first position to a second position.
    In this way, the guide arms can in a simple manner be further prevented from moving in an undesirable manner relative to each other.
    According to an exemplary embodiment, said projection is a rotatable roller.
    A rotatable roller reduces the friction, which means that the force that the motor needs to use to move the cabinet interior from a first position to a second position becomes less compared to a non-rotatable roller. Furthermore, the reduced friction means that any surface coating on the control unit wears off at a slower rate.
    According to an exemplary embodiment, said control unit is a rail.
    A rail may comprise only one plane or be shaped like a horizontal U, so that it at least partially encloses the projection on the guide part.
    According to an exemplary embodiment, said guide part is angled relative to the coupling part at the hinge point at the fastening portion in the plane of the longitudinal extent of the stabilizing device.
    Such an angled stabilizing device prevents the lower guide arm from moving relative to the upper guide arm so that it follows the desired path. Furthermore, an angled stabilizing device means that the longitudinal extent of the guide part can be made shorter compared to a straight stabilizing device, which means that the movement of the stabilizing device is not hindered by the wall bracket. A shorter guide part also results in a better balancing of the stabilizing device around the hinge point at the fastening portion, which means that it is easier to control the stabilizing device. A stabilizing device where the guide part weighs considerably more than the coupling part can be pivoted by its own weight in an undesirable manner. in such a position where the stabilizing device does not affect the conductor arms. This in turn can lead to the stabilizing device being angled in a manner which does not allow the coupling part to cooperate with the coupling unit when the cabinet interior is again moved to such a position where it is desirable for the stabilizing device to actuate the conductor arms.
    According to an exemplary embodiment, an angle between said guide part and said coupling part in the plane of the longitudinal extent of the stabilizing device is between 130 and 160 degrees.
    According to an exemplary embodiment, an angle between said guide part and said coupling part in the plane of the longitudinal extent of the stabilizing device is 145 degrees.
    By choosing such an angle, the lower articulated arm is prevented from moving in an undesired manner relative to the upper articulated arm. Instead, both leaders can follow their intended, that is, natural, path in relation to the wall bracket. The position of the stabilizing device on the guide arm affects which angle is suitable since the purpose of the stabilizing device is to stabilize the guide arms by preventing them from moving substantially outside their natural path. The attachment point of the upper articulation arm in the wall bracket in relation to the attachment point of the lower articulation arm also affects the choice of angle.
    According to an exemplary embodiment, said guide part follows a path which forms an acute angle together with the vertical extent of the wall bracket in a plane which is substantially perpendicular to an imaginary rear wall of the cabinet interior.
    By selecting a suitable angle, the guide part of the stabilizer can be pivoted in a good way, so that the guide arms are further prevented from moving in an undesired manner, i.e. mainly outside their natural path.
    According to an exemplary embodiment, an angle between the path of the guide part and the vertical plane of said wall bracket is between 30 and 60 degrees.
    According to an exemplary embodiment, an angle between the path of the guide part and the vertical plane of said wall bracket is 45 degrees. According to an exemplary embodiment, a ratio between an angle between the path of the guide part and the vertical plane of said wall bracket and the angle between the guide part and the coupling part is between 0.2 and 0.4.
    In this way a desired movement of the stabilizing device can be achieved which in turn prevents unwanted movement of the guide arms.
    According to an exemplary embodiment, it further comprises a cushion arranged at the hinge point at the fastening portion in order to reduce the friction against a sliding path of the wall bracket.
    A cushion reduces the friction against the slide while stabilizing the cabinet when moved between the first and second positions.
    According to another aspect of the invention, the object is achieved by a cabinet device comprising a wall bracket, at least two guide arms, which at one end are pivotably arranged at the wall bracket and at their other end pivotably support a side piece, a control unit arranged at the wall bracket, and a stabilizing device comprising a guide part and a coupling part, which start from a fastening portion. The stabilizing device is pivotally mounted at a hinge point at its mounting portion around a point on a first hinge arm of the cabinet interior, said coupling part being arranged to cooperate with a coupling unit on a second hinge arm of said cabinet interior when the cabinet interior is moved from a first position to a second position. , said stabilizing device preventing the guide arms from moving in an undesired manner relative to each other, said control unit at the wall bracket cooperating with the control part of the stabilizing device when the cabinet device is moved from the first position to the second position.
    Such a cabinet interior according to the invention is stable, i.e. side pieces of the cabinet interior are prevented from moving non-parallel relative to the wall, when the guide arms are in such a way that instability usually occurs in cabinet cabinets of known technology, i.e. the cabinet interior is recessed by the guide arms to a position located within the area so close to a rear wall behind the cabinet interior that the cabinet interior becomes unstable. Thus, the cabinet interior according to the above recess enables substantially the whole way in relation to a rear wall in which the wall bracket is attached. According to an exemplary embodiment, said stabilizing device may have any of the features discussed in the first aspect of the invention.
    According to an exemplary embodiment, said control unit and the vertical extent of the wall bracket form an angle between 30 and 60 degrees in a plane which is substantially perpendicular to an imaginary rear wall of the cabinet interior.
    According to an exemplary embodiment, said control unit and the vertical extent of the wall bracket form an angle of 45 degrees in a plane which is substantially perpendicular to an imaginary rear wall of the cabinet interior.
    By choosing a suitable angle, the interaction of the guide member with the control unit can be facilitated while the movement of the stabilizing device can be controlled in a desired manner, which helps to prevent the movement of the guide arms substantially outside their natural path in which they are substantially parallel in their longitudinal extent.
    According to an exemplary embodiment, said coupling unit on the second guide arm is a rotatable roller.
    A rotatable roller reduces the friction, which means that the force that the motor needs to use to move the cabinet interior from a first position to a second position becomes less compared to a non-rotatable roller. Furthermore, the reduced friction means that any surface coating on the control unit wears off at a slower rate.
    According to an exemplary embodiment, the cabinet interior further comprises at least one sliding path in the form of a circular arc extending perpendicularly from the wall bracket, wherein a cushion arranged at the hinge point at the fastening portion of the stabilizing device is arranged to slide / abut against the sliding path.
    Such a slide is advantageous because it stabilizes the movement of the cabinet interior when it is moved between a first and a second position.
    According to an exemplary embodiment, the cabinet interior further comprises a motor and a belt, the motor being arranged at the upper part of the wall bracket and the belt starting from a roller, which roller is arranged at and driven by the motor, and extends via the first The end of the lead arm attached to the side piece to the other end of the lead arm attached to the side piece.
    In this way, the cabinet interior's mechanism for raising and lowering can be easily operated mechanically. By arranging a motor and a belt on each side of the cabinet interior instead of just a large motor, each unit takes up little space inside the cabinet and the cabinet volume between the motors can be used more efficiently.
    Additional features and advantages of the present invention will become apparent when the appended claims and the following description are studied. One skilled in the art will recognize that various features of the invention may be combined to create embodiments in addition to those described below, without departing from the scope of the invention.

    Description of exemplary embodiments Throughout the description, words such as above, below, upper, lower, etc. are meant to have their usual meaning, i.e. they refer to vertical conditions, when the cabinet interior is in use. In the description below, the recessed and unfolded position need not refer to a fully recessed and a fully unfolded position, respectively, but the recessed and unfolded position can refer to positions that are recessed or unfolded in relation to a previous position of the cabinet interior. By diagonally height-adjustable cabinet interior is meant that the cabinet interior follows an arcuate path when it is raised or lowered and moved both vertically and horizontally.
    Figure 1 schematically illustrates the scope of the invention and shows a height-adjustable cabinet interior 1 in a fully unfolded position. The figure shows a cabinet interior 1, which is mounted inside an existing cabinet 2 and which can be lifted diagonally between a folded-out position and a folded-in position (not shown). The cabinet interior 1 comprises two guide arms 3a, 3b on each side by means of which the cabinet interior 1 can be raised and lowered. The hinge arms 3 are pivotally arranged, in pairs at a wall bracket 10 on each side, in that one end of each hinge arm 3a, 3b is pivotally fastened in the respective wall bracket 10. The cabinet interior 1 also comprises two side pieces / walls 4, a rear wall 5, an upper disc 6 and a lower disc 7. The opposite ends of the guide arms 3a, 3b are pivotably arranged in pairs at the respective side piece 4. In this way the side pieces 4, the rear wall 5 and the upper 6 and lower 7 disc are supported by the guide arms 3a, 3b. The cabinet interior 1 further comprises a motor 8 and a belt 9 on each side. The motors 8 are arranged at the upper part of the associated wall bracket 10 and the belt 9 starts from a roller at each motor 8, which roller is driven by the respective motor 8. The belt 9 extends via the end point of the first conductor 3a which is attached to the side piece 4 to the second conductor 3b end point which is attached to the side piece 4. When the cabinet interior 1 is in its fully extended, or lower, position, it is moved diagonally downwards in relation to its folded-in, or upper, position. In this way, a person who does not reach the height of the cabinet in an upper normal position can easily reach the desired contents of the cabinet. 10 15 20 25 30 10 The side pieces 4 may contain grooves (not shown) for shelves or a smaller cabinet module with shelves can be attached to the side pieces 4. In such cases the rear wall 5, as well as the upper 6 and lower plate 7 can be omitted.
    The raising and lowering mechanism of the cabinet interior 1 is suitably remotely controlled by means of a remote control or alternatively the mechanism can be controlled by means of a button which is arranged in a suitable place, for example at the worktop on a part projecting below the current existing cabinet 2. Even if the cabinet interior 1 is shown as mounted inside an existing cabinet 2 with the door or door 11 mounted on the existing cabinet 2, the door or door 11 within the scope of the invention can also be mounted on the height-adjustable cabinet interior 1. In this way the opening of the cabinet is facilitated without an opening mechanism. needs to be installed.
    Figs. 2a-2d are a series of figures schematically illustrating the function of a stabilizing device 12 according to the invention and the function of a height-adjustable cabinet device 1 comprising a stabilizing device 12 according to the invention. The operation of the stabilizing device 12 according to the invention is described in detail below.
    Fig. 2a is a perspective view of an exemplary stabilizing device 12 according to the invention mounted on a diagonally height-adjustable cabinet device 1, where the cabinet device 1 is in a recessed position, in which the stabilizer device 12 acts on the guide arms 3a, 3b of the cabinet device 1. The cabinet interior 1 is mounted in an existing or a new cabinet 2 with standard dimensions in, for example, a kitchen. The cabinet interior 1 comprises on both sides a vertical wall bracket 10, two slides 13a, 13b, two guide arms 3a, 3b, a control unit in the form of a rail 14, a side piece 4, a motor 8 and a belt 9. A stabilizing device 12 according to the invention is pivotably mounted at the upper of the conductor arms 3a, 3b. As can be seen from the figure, the cabinet interior 1 comprises two sets of all constituent parts except shelves and the like, which sets are symmetrically arranged on each side of the cabinet interior 1. That is, one set is arranged on one side of the cabinet interior 1 and the other up the set is arranged on the other side of the cabinet interior 1 as a mirror image of the first set. With regard to details of the invention, essentially only one of the sets will be described, but the same also applies to the other set.
    Figure 2a shows a recessed figure of only the stabilizing device 12, which comprises a fastening portion 15, a guide part 16 and a coupling part 17.
    The mounting portion 15, located between the guide member 16 and the coupling member 17, includes a through hole 18 for pivotable attachment to the upper guide arm 3a.
    The coupling part 17 comprises a continuous elongate recess 19. The extent of the recess 19 from one end of the stabilizing device 12 is chosen in such a way that the cabinet interior 1 can be folded substantially all the way to an existing rear cabinet wall (not shown). Even if the recess 19 is shown as continuous in the figure, it does not have to be. Instead, the recess 19 can be shaped as a recess on the side of the stabilizing device 12 facing the upper guide arm 3a. The guide part 16 comprises a rotatable roller 20 which is arranged in the free end 21 of the guide part. The roller 20 is rotatable in the direction of movement of the guide part. The angle oi between the guide part 16 and the coupling part 17 is suitably between 130 and 160 degrees. An angle oi of 145 degrees is particularly suitable.
    The guide part 16 and the coupling part 17 can be designed in such a way in relation to each other so that the stabilizing device 12 is angled in a desired way when it does not affect the conductor arms 3a, 3b. That is, the weight ratio of the guide member 16 and the coupling member 17 is such that the gravity acting on the guide member 16 causes the stabilizing device 12 to end up in a desired position relative to a horizontal plane through the articulation point at which the stabilizing device 12 is attached to the guide arm 3a. In this way, the coupling unit 34 on the lower guide arm 3b can easily cooperate with the coupling part 17 when the guide arms 3a, 3b are moved from a position where the stabilizing device 12 does not affect the guide arms 3a, 3b to a position where the stabilizing device 12 begins to affect the guide arms 3a, 3b . Alternatively, the stabilizing device 12 can be attached to its fastening portion 15 to the upper guide arm 3b in such a way that a resistance needs to be overcome when the stabilizing device 12 is pivoted. In this case, this resistor is of such a size that it counteracts the force of gravity of the guide part 16 and the angle of the stabilizing device 12 is maintained without external influence when the stabilizing device 12 does not affect the guide arms. The guide part 16 may alternatively comprise a non-rotatable roller or some other type of projection. The stabilizing device 12 may further comprise a cushion 22 which is intended to slide against an upper sliding path 13a of the wall bracket. Alternatively, the cushion 22 may be a free-standing part mounted to the stabilizing device 12.
    The stabilizing device 12 is preferably made of some type of metal, but may also be made of composite, wood or a plastic material with sufficient strength. This also applies to the rail 14, the roller 34, the wall bracket 10 and its projecting parts, the guide arms 3a, 3b, the slides 13a, 13b, the spacers 33 and the side pieces 4.
    The vertical wall bracket 10 extends substantially along the height of the existing cabinet 2. The wall bracket 10 has a rear portion 23 and a side portion 24, which are arranged substantially perpendicular to each other. On the side portion 24 of the wall bracket 10 there are two projecting brackets 25, 26 for the conductor arms, of which the lower 25 is located in the lower end portion of the wall bracket 10 and the upper 26 is located at a suitable distance therefrom to ensure the device becomes stable while desired. to be able to fold the guide arms 3a, 3b so far in relation to the wall bracket 10 that the cabinet interior 1 is substantially recessed all the way relative to a rear wall of the existing cabinet 2.
    Such a distance is about one third of the entire height of the wall bracket 10.
    The distance can be varied approximately 10% in any direction, without this requiring major modifications of the stabilizing device 12 according to the invention. An excessive distance between the guide arms means that the stabilizing device needs to be modified in such a way that there is a risk that the wall bracket 10 prevents the stabilizing device 12 from moving because the guide part 16 is stopped by the wall bracket 10.
    The wall bracket 10 comprises two sliding paths 13a, 13b which are intended to stabilize the movement of the guide arms 3a, 3b. The slides 13a, 13b are shaped as circular paths which have such an extent that the guide arms 3a, 3b can follow them along the entire movement of the guide arms 3a, 3b. The lower slide 13b extends between the lower 25 and upper 26 attached to the guide arms 3a, 3b in such a place that a cushion 27 arranged on the lower guide arm 3b can abut against the slide 13b when the guide arm 3b is moved between a recessed and a folded-out position or vice versa. One end of the lower slide 13b is bent to form an end support 28 for the lower guide arm 3b in its fully extended position. The upper slide 13a extends at such a distance above the bracket 26 for the upper guide arm 3a that the cushion 22 arranged on the stabilizing device 12 or the upper guide arm 3a can abut against the upper slide path 13a when the upper guide arm 3a is moved from a recessed position to an unfolded position or vice versa. Above the upper slide 13a, the guide unit 14 in the form of the rail 14 is arranged at the wall bracket 10. The rail 14 is arranged inclined downwards so that an acute angle is formed between the rear portion 23 of the wall bracket 10 and the longitudinal extent of the rail 14. This angle is suitably between 30 and 60 degrees. An angle of 45 degrees is particularly suitable. In the exemplary embodiment of the figure, the rail 14 is formed by a sheet metal plate which is bent so as to form a fastening portion 29 and a rail portion 30. The fastening portion 29 is provided with two through holes for fastening by means of a suitable fastening element to the side portion 24 of the wall bracket 10. and the upper slide 13a. The rail 14 may alternatively be formed as part of the wall bracket 10. The rail 14 may also be part of the stabilizing device. The rail 14 can furthermore be fastened only to the side portion 24 of the wall bracket 10.
    In the upper end portion of the wall bracket 10, the motor 8 and a roller 32 are arranged.
    The roller 32 is rotatably arranged between two fastening portions 31 which extend perpendicularly from the rear portion 24 of the wall bracket 10 about a substantially horizontal axis which is parallel to the rear portion 24 of the wall bracket 10. On the roller 32 the belt 8 is arranged. The strap 8 is attached at one end to the roller 32 and at its other end attached to an end portion of the lower guide arm 3 which is located at the side piece 4 of the cabinet interior 1. In between, the strap 8 is passed over the attachment point of the upper guide arm 3a to the side piece of the cabinet interior. 4.
    The side piece 4 of the cabinet interior 1 extends substantially along the entire height of the existing cabinet 2 and thus also approximately the longitudinal extent of the wall bracket 10. The side piece 4 is arranged to be raised and lowered at the wall bracket 10 by means of the guide arms 3a, 3b.
    One end of the lower guide arm 3b is pivotally arranged in a bracket 25 at the lower end portion of the wall bracket 10. A distance 33 is arranged between the lower guide arm 3b and the bracket 25. The distal end of the lower guide arm 3b relative to the wall bracket 10 is pivotably arranged substantially at a vertical center line on the side piece 4 of the cabinet interior 1. The length of the lower guide arm 3b is such that the cabinet interior 1 can be folded out in the desired manner at the same time. the cabinet interior 1 is sufficiently stable. In the preferred embodiment of Figure 2a, the lower guide arm 3b extends between its bracket 25 on the wall bracket 10 and a point approximately one third from the upper end edge of the side piece 4. The upper guide arm 3a is designed in a corresponding manner and fastened correspondingly to its bracket at the wall bracket 26 and the upper end portion of the side piece 4, respectively. The transverse extent of the guide arms 3a, 3b is such that it allows the cabinet interior 1 to be folded in in the desired manner.
    On the lower guide arm 3b a coupling unit 34 (a mold-adapted projection) in the form of a rotatable roller 34 is arranged. Alternatively, the coupling unit may be a non-rotatable roller or some other type of projection.
    An exemplary stabilizing device 12 according to the invention is arranged at the cabinet interior 1. The stabilizing device 12 is pivotally arranged at the upper guide arm 3a at the mounting portion 15 of the stabilizing device 12, in such a way that it can rotate about an axis perpendicular to both the upper the longitudinal extent of the guide arm 3a and the longitudinal extent of the stabilizing device 12. The stabilizing device 12 is further arranged on the guide arm 3a in such a way that the articulation point around which the stabilizing device 12 is pivotable in line with a center line of the slide 13a in its longitudinal extent. In this way, the cushion 27 at the articulation point can slide towards the slideway 13a. within the scope of the invention, other locations along the guide arm 3a are also possible, but this may mean that it is desirable to modify the extent and location of the slideway 13a, the length of the guide part 16 and the length and location of the rail 14.
    A ratio of the angle between the coupling lens part 17 and the guide part 16 of the stabilizing device 12 and the angle between the rail 14 and the rear part 23 of the wall bracket 10 is between 2.9 and 3.6. The relationship between the two angles contributes to the stabilization of the cabinet interior 1 being possible. This relationship between the angles is preferred when the stabilizing device 12 is attached to the guide arm 3a according to the embodiment of the figures. If the stabilizing device 12 is attached to another position, this may mean that it is desirable to modify the angles of the stabilizing device 12 and the rail 14, respectively. Furthermore, this may mean that the length of the guide part 16, the coupling part 17, the recess 19 of the coupling part 17 and the rail 14 needs to be modified.
    In the retracted position, the roller 20 on the stabilizing device 12 is in its end position closest to the wall bracket 10 on the rail 14. The roller 34 on the lower guide arm 3b is correspondingly in its end position at the recess 19 on the coupling part 17. Since the guide arms 3a, 3b are connected in relation to each other they are prevented from being substantially parallel along their longitudinal extent. The rail 14 on the wall bracket 10 further helps to prevent the guide arms from moving in an undesirable manner, since the rail 14 cooperates with the roller 20 on the stabilizing device 12 and forces the stabilizing device 12 to move in a predetermined manner. In this way, the lower end of the cabinet interior 1 is stable and substantially unshakable, despite the fact that the cabinet interior 1 folds all the way into a rear wall of the existing cabinet 2 in which the cabinet interior 1 is mounted.
    In the fully retracted position of the cabinet interior 1, the belt 9 emanating from the roller 32 at the motor 8 is completely wound up at the roller 32 apart from the part extending to the end of the lower guide arm 3b at the side piece 4.
    Fig. 2b is a perspective view of an exemplary stabilizing device 12 according to the invention mounted on a diagonally height-adjustable cabinet interior 1, where the cabinet interior 1 is in a slightly extended position.
    In the slightly extended position in Figure 2b, the stabilizing device 12 is in its active area, i.e. in the area where the stabilizing device 12 counteracts instability of the cabinet interior 1 by influencing the conductor arms 3a, 3b. The roller 20 on the guide part 16 is still exactly in contact with the rail 14 and the roller 34 on the lower guide arm 3b cooperates with the recess 19 at the coupling part 17. When the guide arms 3a, 3b are moved towards a second more extended position relative to a previously first folded position their mutual distance at the same time as the distance of the guide arms 3a, 3b relative to the wall bracket 10 at the respective end point attached to the side piece 4 increases, since the guide arms 3a, 3b are pivotably arranged at the end point attached to the wall bracket 10. This leads to the stabilizing device 12 is pivoted about the shaft located at its mounting portion 15 and at which the stabilizing device 10 is arranged at the upper guide arm 3a. Thus, the angle between the coupling part 17 of the stabilizing device 12 and the vertical extent of the wall bracket 10 increases in the plane of the longitudinal extent of the stabilizing device 12.
    Fig. 2c is a perspective view of an exemplary embodiment of a stabilizing device 12 according to the invention mounted on a diagonally height-adjustable cabinet device 1, where the cabinet device 1 is in a partially extended position, in which the stabilizer device 12 does not affect the conductor arms 3a, 3b.
    In the unfolded position in Figure 2c, the roller on the guide member 16 is not in contact with the rail 14 and the roller 34 on the lower guide arm 3b does not cooperate with the coupling member 17. Thus, Figure 2c illustrates the boundary position or end position of an area where the stabilizer 12 is passive or non-passive. active, that is, does not affect the conductor arms 3a, 3b. In this area, the cabinet interior 1 is sufficiently stable in itself because the distance of the guide arms 3a, 3b relative to each other is large enough to prevent the lower part of the cabinet interior 1 from moving relative to the rear wall in an undesired manner. This area corresponds to the area in which cabinet fittings of prior art are allowed to move.
    Fig. 2d is a perspective view of an exemplary embodiment of a stabilizing device 12 according to the invention mounted on a diagonally height-adjustable cabinet device 1, where the cabinet device 1 is in a fully extended position, in which the stabilizer device 12 does not affect the conductor arms 3a, 3b.
    In the unfolded position in Figure 2d, the roller 20 on the guide member 16 is not in contact with the rail 14 and the roller 34 on the lower guide arm 3b does not cooperate with the coupling member 17. Figure 2d illustrates one end point of the area where the stabilizing device 12 is passive or inactive , that is, does not affect the conductor arms 3a, 3b. This end point corresponds to the end point of cabinet fittings of prior art. In the fully extended position in Figure 2d, the cushion 15, 27 on the respective guide arm 3a, 3b at the free end of the respective sliding path 13a, 13b is on the wall bracket 10. The lower guide arm 3b rests against the end support 28 on the lower sliding path 13b. In this position, the belt 9 arranged on the roller 32 at the motor 8 is as wound out as possible. The raising and lowering mechanism of the cabinet interior 1 is driven by the motor 8 by unwinding the belt 9 when lowering or unwinding when raising.
    When the cabinet interior 1 is moved back towards its recessed position in Figure 2a, the roller 34 on the lower guide arm 3b is inserted into the recess 19 on the coupling part 17 when the conductor arms 3a, 3b and the cabinet interior 1 pass the position in Figure 2c (in opposite direction to the arrow in Figure ) and the stabilizer enters its active area. The recess 19 on the coupling part 17 forms a groove in which the roller 34 is forced to move so as to prevent the guide arms 3a, 3b from moving in an undesired manner relative to each other. In the exemplary embodiment in Figures 2a-2d, this means that the conductor arms 3a, 3b are prevented from not being parallel in their longitudinal extent.
    When the cabinet interior 1 is moved further towards its recessed position in figure 2a, the roller 20 on the guide part 16 is forced to cooperate with the rail 14 by running over it. In this way, the guide arms 3a, 3b are further prevented from moving in an unfavorable manner.
    By combining the interaction of the coupling part and the coupling unit with the interaction of the control part and the control unit, the cabinet interior is stabilized, which means that the side pieces of the cabinet interior are prevented from moving non-parallel in relation to the wall.
    When raising and lowering, i.e. folding out and folding in, the cabinet interior 1 follows an arcuate path and is further stabilized by the cushions 22, 27 arranged at the guide arms 3a, 3b abutting against the sliding paths 13a, 13b on the wall bracket 10.
    It will be appreciated that a variety of modifications of the above-described embodiment of the invention are possible within the scope of the invention, as defined by the appended claims. Thus, for example, as described above, the recess 19 at the coupling part 17 does not have to be continuous but can only be a recess which forms a groove, or the roller 34 on the lower guide arm 3b can be fixed and not rotating. Furthermore, the roller does not have to be in the form of a roller but can be a projection with an arbitrary shape, as long as its function is the same.
    In an alternative embodiment, the guide part 16 of the stabilizing device 12 comprises a rail instead of a rotatable roller 20 and the guide unit 14 at the wall bracket 10 is instead in the form of a rotatable roller. Such a rail of the stabilizing device 12 extends at an angle from one side of the end of the guide part 16, on which side the angle between the guide part 16 and the coupling part 17 is greatest, towards the mounting portion 15 and the other side of the guide part 16 in such a way as desired movement of the stabilizing device 12 is achieved. In this way an angle is formed between a longitudinal extent of the guide part 16, on the side where the angle between the guide part 16 and the coupling part 17 is largest, and the rail which is between 7 and 15 degrees. Preferably the angle is 11 degrees.
    The rotatable roller on the wall bracket is in this embodiment arranged at the end portion of the upper slideway 13a at the wall bracket 10.
    In a further alternative embodiment, the coupling unit 17 on the lower guide arm 3b is in the form of two parallel elongate projections forming a groove and the coupling part 17 of the stabilizing device 12 comprises a rotatable roller which is arranged in such a way that it can be guided by the groove between the projections on the lower guide arm 3b.
    Instead of being mounted on the upper guide arm 3a, the stabilizing device 12 within the scope of the invention can also be mounted at a hinge point on the lower guide arm 3b in a similar manner as described above. In such an embodiment, the stabilizing device 12 can be slightly modified, inter alia, in that the guide part 16 and the coupling part 17 are placed in an inverted manner relative to the joint point. The coupling unit 34 is further arranged on the upper guide arm 3a and the control unit 14 is modified and positioned so that it can cooperate with the projection on the guide part 16. Such a control unit 14 projects near the bracket 25 for the lower guide arm 3b so that an obtuse angle is formed in relation to the vertical extent of the rear portion 23 of the wall bracket 10.
    The number of conductor arms 3a, 3b of the cabinet interior 1 is not limited to two but can also be more. In such cases, the number of stabilizing devices 12 can be increased to a suitable number to obtain sufficient stability. Even if the cabinet interior 1 is described as mounted in an existing cabinet 2, it can of course also be mounted in a completely new ordinary cabinet with standard dimensions after this has been mounted in the desired location. 19 The alternative embodiments above can also be combined with each other.
