Description

  The present invention is a drawer for a self-supporting box that can be pulled out along the linear guides on both sides, and has a cover at the end area on the front side. Locking device allows the cover to be locked to the front end area on the side where the drawer is pulled out on one side and the box on the other side to close the opening when the drawer is pulled out of the box It relates to a drawer for a free-standing box.

  In particular, in the case of a self-supporting floor cabinet used as partition furniture in a kitchen facility, for example, it is necessary that the drawer fitted in the box can be pulled out on both sides and can be accessed from both sides. In that case, it is necessary to provide a cover on both sides of the drawer which can be drawn on both sides in order to be able to meet the aesthetic requirements. Here, the function of the drawer with the cover on both sides is that the cover on the drawer side of the drawer is locked with the drawer, while the cover on the opposite side covers the box opening caused by the drawer being pulled out. Must be designed to be locked with the box.

  As a solution, it is known that the height position is changed as soon as a drawer that can be pulled out on both sides starts to be pulled out, and the corresponding cover lock mechanism is activated by this height position change. However, this has the disadvantage that the drawer operation is difficult, especially when the weight of the items stored in the drawer is relatively large. Further, this method is possible only when the drawer is simply drawn, and is impossible when all the drawers are drawn.

  Therefore, an object of the present invention is to create a drawer that can be pulled out on both sides without consuming a great deal of force regardless of the weight of the stored item, and in addition, it can be pulled out entirely.

  According to the present invention, according to the invention, each locking device is attached to a cover, holds a locking element that can be slid laterally with respect to the pulling direction, a first cam mounted on the drawer, and a box. It consists of a second cam that can be attached. When the drawer is pulled out, the lock element reaches the lock area of the first cam while being controlled by the second cam, and when the drawer is pulled away from the cover, the lock element is This is solved by the fact that the first cam and the second cam are shaped so as to reach the lock area of the second cam while being controlled by one cam.

  With this solution, optimum movement is achieved when the drawer is pulled out on both sides along the linear guide, regardless of how heavy the storage in the drawer is.

  In an advantageous manner, two locking devices are provided for both covers, respectively, which are each arranged in the side edge area of the corresponding cover. Thereby, these locking devices can be stored in the side space between the drawer and the box boundary. A linear guide is also housed in this, so that optimum holding for the cover is achieved.

  In a further advantageous embodiment of the invention, each holding part is made of one fastening piece fastened to the cover, one leg of which protrudes in the direction of withdrawal from the cover, and is spaced from each other. A holding element made of two open plates is fastened in an adjustable manner, and a locking element in the form of a pin can be inserted into a vertical slit in each of the plates. ing. As a result, the cover can be adjusted in an optimum manner with respect to the height position and the lateral position of the cover on the one hand in the drawer drawing direction on the one hand and on the other hand on the adjacent front cover on the other hand. In addition, the creation of the holding element made by two plates, each with a longitudinal slit, makes an optimum guide for the pin acting as a locking element.

  The guide of the pins within the longitudinal slits of both plates of the holding element is improved by providing a guide surface supported by the plates at both end areas of the pins.

  In an advantageous manner, the first cam and the second cam are arranged to overlap and stand between the plates when the drawer is pushed into the box. In addition to saving space, this arrangement also allows the locking element to operate in an optimal manner.

  In an advantageous manner, the first cam has a first slit-like recess which acts as a track cam for the locking element that opens towards the cover, which descends towards the area opposite the cover, The end region, which goes down directly below, consists of a plate that forms a lock region, the second cam has a second slit-like recess that also acts as a track cam for the lock element that opens towards the cover, This is the plate that forms the lock area at the end area that rises toward the area opposite to the cover and rises directly above. Both of these cams can now be manufactured very simply, so that the control of the locking element is possible in an optimal manner.

  In a further advantageous form of the invention, linear guides are arranged on both sides of the drawer, each linear guide comprising a first rail fastened to the drawer and a second rail that can be fastened to the box. Both rails are connected to each other by a guide element so as to be movable in the vertical direction. The first cam is fastened to the first rail, and the second cam is fastened to the second rail. This arrangement allows the unit to be manufactured and assembled on the factory side, thereby facilitating assembly into the box on site.

  Advantageously, a stopper is attached to the holding element and cooperates with a stop element attached to the second cam, thereby limiting the movement of the covering into the box. This allows exact positioning of the cover in the box.

  In an advantageous manner, the drawer is made up of a bottom plate, two side walls and two front walls, where the side walls consist of a cover plate covering the linear guide and the cam, each time the cover is pulled out of the drawer. It touches the corresponding front side. In this way, a simple structure is created, and in addition, the guide and cam are protected from dirt.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  Illustrated in FIG. 1 is a box 1 that constitutes a self-supporting floor cabinet of kitchen equipment, such as used for example in a partition. In its upper area the box 1 has a drawer 2. The drawer 2 can be drawn out on both sides of the box 1, and the drawn-out state of the drawer 2 is drawn with a solid line, and the drawer 2 when drawn out on the other side is drawn with a one-dot chain line. When pulling out the drawer 2 on each side, the first cover 3 is locked with the drawer 2 and, on the other hand, locked with the second cover 4, which results from pulling out the drawer on this side.

  As can be seen from FIG. 2, the drawer 2 is provided with one linear guide 5 on each side. Each of the linear guides 5 includes a first rail 6 fastened to the drawer 2. Furthermore, the linear guides 5 each include a second rail 7 that can be fastened to the box 1. Both rails 6 and 7 are guided by a guide element in a manner known in the art, for example a ball guide which allows the first rail 6 to swing while being guided in the pull-out direction with respect to the second rail 7. Are connected to each other.

  A first cam 8 is fastened to each of the first rails 6. This first cam 8 now moves with the drawer 2 when the drawer 2 is withdrawn from the box 1 (FIG. 1). One second cam 9 is fastened to each of the second rails 7 in the end region. This second cam 9 is now held against movement on the box side.

  Both covers 3 and 4 are each fastened with a holding part 10, and as will be seen later, the locking element is held there. This holding part 10 is also arranged on the covers 3 and 4 so as to cooperate with the first cam 8 and the second cam 9 as will be described later.

  Each holding part 10 is made from a fastening piece 11, which in this embodiment is shaped as an angle 11 fastened to the respective covering 3 or 4 by one leg 12. A holding element 14 is fastened in an adjustable manner to the other leg 13 protruding in the pull-out direction from the respective covering 3 or 4. This holding element will be described in detail later.

  As can be seen from this illustration, the drawer 2 consists of two side walls made of a bottom plate 15, two front walls 16 and 17, and cover plates 18 and 19 (FIG. 1). Cover the cams 8 and 9.

  FIG. 3 shows the locking device as arranged in various ways for the drawer 2 as described above. The holding element 14 consists of two plates 20 and 21 spaced apart from one another, each with a longitudinal slit 22. The vertical slit 22 is arranged perpendicular to the drawing direction. A lock element 23 in the form of a pin 24 is inserted into the vertical slit 22. The pin 24 has one guide surface 25 in each of the end regions. When the locking element 23 is inserted in the longitudinal slit 22, both guide surfaces 25 are supported by the plates 20 and 21, so that the locking element 23 is guided in an optimal manner. The lock element 23 can be slid along the vertical slit 22.

  The first cam 8 fastened to the first rail 6 includes a plate 26. The plate 26 has a first slit-shaped recess 27 that serves as a track cam for the locking element 23. The first slit-shaped recess 27 is open toward the cover 3. This first slit-shaped recess descends towards the area opposite to the cover 3 and ends in an end area 28 that descends directly below it, which forms the lock area.

  The second cam 9 consists of a plate 29 fastened to the second rail 7, which has a second slit-like recess 30 which also serves as a track cam for the locking element 23. The second slit-shaped recess is also open toward the cover 3 and rises toward the area opposite to the cover and ends in the end area 31 that rises directly above it. create.

  FIG. 4 is a cross-sectional view showing the first rail 6 and the second rail 7 of the linear guide 5. A first cam 8 is fastened to the first rail 6, and a second cam 9 is fastened to the second rail 7. Both cams 8 and 9 are arranged to stand between the plates 20 and 21 of the holding element 14. In this figure, the locking elements 23 inserted into the longitudinal slits 22 of the plates 20 and 21 can also be seen. Here, as will be described later, the outer area of the locking element 23 is passed through the longitudinal slits 22 of both plates 20 and 21, and the first cam 8 and the second cam 9 of this locking element 23. It can be seen that the vertical slit 22 can be moved vertically.

  As can be seen from FIG. 5, when the drawer 2 is pulled out, the locking element 23 is in the vertical area 28 of the first cam 8. Thus, both plates 20 and 21 of the holding element 14 are locked to this first cam 8 via a locking element 23 in the lower region of the longitudinal slit 22. The cover 3 is now held by this drawer 2. Both plates 20 and 21 are here supported by the first rail 6 and in addition are held by a stop element 32 attached to the first cam 8. The stop element cooperates with the recess of the holding element 14 and here serves as a stopper 33.

  When the cover 3 is in this fixed position with respect to the drawer 2, the cover 3 can be adjusted between the holding element 14 and the angle 11 (FIG. 2), as described above, so that it matches the front 34 of the box 1. Can be adjusted.

  As shown in FIG. 5, when the drawer 2 is pushed in from the pulled-out position, the first cam 8 is swung over the second cam. This is because both cams are arranged side by side. The locking element 23 now approaches the ascending region of the second slit-like recess 30 of the second cam 9.

  As can be seen from FIG. 7, when the drawer 2 is further pushed into the box 1, the lock element 23 gradually passes through the upward slit region of the second slit-like recess 30 of the second cam 9 and the vertical slit of the holding element 14. Go up the 22nd. However, the lock is not released yet.

  As shown in FIG. 8, when the drawer 2 is completely pushed into the box 1, the lock element 23 further rises along the contour of the second slit-shaped recess 30. Here, the locking element 23 arrives from the vertical area 28 of the first slit-shaped recess 27 of the first cam 8. However, the locking element simultaneously reaches the vertical area 3 1 of the second slit-like recess 30 of the second cam 9. As a result, the cover 3 is held at a position in contact with the box 1 with the second cam 9 as a reference, as shown in FIG. Now, the drawer 2 has reached the state of being pushed into the box.

  Now, when the drawer 2 is pulled out on the other side, i.e. in a direction away from the cover 3, the lock element 23 moves up through the ascending region of the first slit-shaped recess 27 of the first cam 8 while being controlled. Then, it reaches the vertical area 31 of the second slit-like recess 30 of the second cam 9. Thereby, the holding element 14 and the cover 3 together therewith are locked by the second cam 9 in a fixed position with respect to the box 1.

  When the drawer 2 is further pulled away from the cover 3, the first cam 8 comes out of the area of the second cam 9, and the lock element 23 is at the upper position and the vertical portion of the slit-like recess of the second cam. It remains standing in the zone 31 and is held by the spring element 35. The lock element 23 now exits from the first slit-shaped recess 27 of the first cam 8. The cover 3 is now held in a position that closes the drawer opening of the box 1.

  In the reverse operation, the lock operation steps described above are performed in the reverse order. On the opposite side of the drawer, the lock operation steps are simultaneously performed in the reverse order.

  With this device, the cover can be locked and unlocked in an optimal manner together with the drawer 2 or the box 1 which can be moved respectively. The movement characteristics of the drawer are not impaired.

  A buffer element and a pull-in aid can be attached to this drawer in an advantageous and known manner. With this element, which is made in duplicate, each at the same time, end position is buffered when the drawer is closed, and at the same time the drawer is placed in the correct retracted position. This prevents the drawer from running out and jumping out from the other side when closed strongly.
