Description

  The present invention relates to a movable furniture portion having a rail body disposed between a rear wall portion and a front panel, and more particularly to a movable drawer portion. The rail body is attached to the front panel by a rotatable adjustment member, and the front panel is inclined by the rotation of the adjustment member.

  This type of movable furniture or drawer is already known, and is particularly used in front panels of multiple drawers stacked or juxtaposed in one or more furniture frames (main bodies). Function to adjust. These adjustment functions are used particularly when the furniture is installed so that the arrangement surfaces on the front side of the furniture are as uniform or coincident as possible to satisfy aesthetic requirements.

  The prior arts DE 9001486U1, DE 19507322U1 and DE 19830740A1 are connected to the rail body by means of a rotating (with thread) adjustment member (connection sleeve 16 in DE 9001486U1, adjustment nut 4 in DE 29507322U1, adjustment nut 16 in DE 19830740A1). The present invention relates to a furniture drawer extending member including a front panel whose inclination can be adjusted by rotation of an adjusting member by a mountain. AT387894B discloses and illustrates the adjustment of the tilt of the front panel by rotation of the right and left threads. DE3819512C1 discloses in the embodiment shown in FIG. 9 the adjustment of the inclination by the rotation of the adjusting member (47) with the right and left threads in relation to the shelf structure.

  For this purpose, the German utility model specification (DE 8912349) discloses a drawer rail. Here, screw elements are suspended from the front panel and are connected to the rail by means of threads. This rotation of the screw element causes a change in the space between the rear wall and the front panel, the front panel being inclined with respect to the rest of the drawer. The disadvantage here is that the screw element is only suspended from the front panel and can be connected in a state of being relatively fixed to the front panel only by the sleeve being pushed back.

  It is an object of the present invention to provide an improved adjustment mechanism for the tilt of the front panel of the drawer that is improved and simplified compared to the prior art.

  In the movable furniture portion of the present invention, this object is achieved by rotating the adjustment member to change both the adjustment member gap relative to the front panel and the adjustment member gap relative to the rail body. That is, when the adjustment member is rotated, both the front panel and the rail body move relative to the adjustment member. This allows further improved adjustment. This is because the half rotation of the adjusting member provides a length adjustment that requires a full rotation of the screw element in the conventional structure.

  In one preferred embodiment, the adjustment member is connected to the front panel and the rail body by respective threads. One thread is the right thread and the other is the left thread. Therefore, the total length of the rail changes correspondingly by the rotation of the adjusting member (the rotation axis is parallel to the rail). Furthermore, a screw connection provides an improved mounting state over the hanging engagement.

  Although the front panel itself and the rail body certainly have corresponding threads for the adjusting member, the front panel fixing element is preferably connected to the front panel by means of an unfoldable connection Advantageously, the thread of the rail body is provided on the connecting element provided above and preferably connected to the rail body by a press-fit connection (press-fit connection). In this case, the expansion connection may be a connection by parallel pins fixed to the front panel.

  More preferably, the adjustment member has a male thread and a female thread. In this case, the male thread of the adjustment member engages with the corresponding thread of the rail body or its connecting element, and the female thread of the adjustment member engages with the corresponding thread of the front panel fixing element To do.

  In another example, the adjustment member has two guide slots. When the guide projections of the front panel fixing element and the connecting element are engaged with these guide slots and the adjusting member rotates, the gap between the front panel and the rail body changes.

  Yet another example of such a structural design is to provide, for example, a wedge-shaped surface on the adjustment member. When this is rotated, both the rail body and the front panel are pulled apart or attracted. Alternatively, a tapered wedge-shaped surface can be provided inside the adjustment member, and the rail body and the front panel can be pushed back by rotation thereof. It is also possible to provide a cable or the like led inside. The cable is now tensioned by the rotation of the adjustment member, or the load is removed by the action of the protrusion acting on the cable, providing adjustment on both sides. Alternatively, it is possible to use a band that is twisted by rotation and narrows the distance between both sides. Further, the elastic part can be used to provide an adjusting action by pressing or displacing each side by rotation on both sides.

  In yet another embodiment, the adjustment member is in the form of an adjusting cylinder, preferably with irregularities on its peripheral surface. In this case, the unevenness is particularly easy to handle in terms of adjustment.

  In yet another embodiment, the rail body is connected to the rear wall by a snap connection element and the adjustment member is covered with a displacement cover cap. In this case, the cover cap contributes to aesthetic enhancement and protects the completed adjustment mechanism.

  In still another embodiment, the front panel and the rear wall are connected to each other using a frame on the lower side of the rail body. In this connection structure, since the spring is used for the connection element between the front panel and the frame, the front panel can be inclined by the rotation of the adjusting member. As described above, by using the spring, it is possible to suppress the stress generated when the inclination is excessive. If not suppressed, this stress will especially damage the connection between the frame and the front panel. This arrangement provides a wedge-shaped gap between the front panel and the frame depending on the degree of tilt.

  The furniture itself having the movable furniture portion described in claims 1 to 10 of the present specification is also an object of the present invention.

    1 and 2 illustrate a furniture 15 having a furniture frame 16 into which three drawers 1 are pushed. The enlarged portion E indicates the inclination of the two front panels that are inclined with respect to the orientation direction of the frame 12 and the furniture frame 16. By this inclination, the front panel 3 of the furniture 1 is given a scale-like appearance having a step. This tilt is corrected by the adjusting mechanism according to the invention.

  FIG. 3 illustrates a movable furniture section or drawer section 1 including at least a rear wall section 2, a front panel 3, a drawer frame 12 with a drawer bottom and two rail bodies 4 with a cover cap 11.

  FIG. 4 illustrates the rail 19, illustrating the rail body 4, the cover cap 11, the front panel fixing element 7 and the snap-fit connecting element 10.

  FIG. 5 is an exploded view of the rail 19. Here, an adjusting mechanism in the form of an adjusting member 5 associated with the connecting element 8 and the front panel fixing element 7 is shown. In this case, the male thread 6 a of the adjusting member 5 engages the corresponding thread 6 b of the connecting element 8, and the female thread 6 c is provided in connection with the corresponding thread 6 d of the front panel fixing element 7. After the connecting elements 8 are inserted into the rail body 4, they are preferably connected in a press-type manner. The rail body 4 can include a rectangular cylindrical steel member whose corners are curved. The connecting element 8 and the snap-fit connecting element 10 are combined with the rail body 4 by a push-type connection. The snap-fit connecting element 10 preferably engages the rear wall 2 in the lateral direction. The adjustment member 5 has irregularities 9 for easy handling. Further, the adjusting member 5 is provided with a wrench size portion 20 and is used for adjusting or rotating the adjusting member 5 with a suitable tool (for example, an open wrench).

  6 and 7 are side views for comparison of the drawer 1. Since the cover cap 11 is pushed back, the adjusting mechanism in each figure can be seen. The gap X between the adjusting member 5 and the front panel fixing element 7 and between the rail body 4 is clearly illustrated in the detailed view A. After the rotation has been carried out (see detail drawing D), the gap X changes on both sides. If the corresponding thread pitch is given, a half turn of the adjustment member 5 provides an amount (interval) corresponding to the length that changes in one conventional turn.

  FIG. 8 illustrates a large slope of the front panel due to improper settings, too short rails 19 or other irregularities. As a result, a large stress is generated in the connection region of the individual members of the drawer 1. In order to prevent such a heavy load or excessive stretching, a spring 14 is provided on the connecting element 13 between the front panel 3 and the frame 12, and a front brace (here) is attached to the front panel 3. The frame 12 is tilted with respect to (not shown). This creates a gap 17 between the front panel 3 and the frame 12.

  FIG. 9 illustrates the inclination of the front panel 3 of the drawer 1 which has been corrected unlike FIG.

  FIG. 10 illustrates another example of a two-rail with two adjustable rails 19 placed on each side wall of the drawer 1.

  FIG. 11 is a schematic diagram illustrating another example of the adjusting member 5, preferably provided with a mounting fitting gap, having two guide slots 20 provided in the adjusting member 5. . The guide projections 21 of the front panel fixing element 7 and the guide projections 21 of the connecting element 8 are guided into these guide slots 20. FIG. 12 is a schematic sectional view thereof. When the adjustment member 5 is rotated clockwise, the guide protrusion 21 moves in the inclined guide slot 20, and the gap between the adjustment member 5 and the front panel fixing element 7 or the gap between the connection elements 8 is changed. Similarly, FIG. 13 illustrates a gap X that varies on both sides between the adjustment member and the front panel or between the drawer boxes. FIG. 14 is a schematic cross-sectional view showing the position of the adjusting member 5 after rotation.

  As described above, in the present invention, the orientation of the panel with respect to the drawer, the orientation of the drawer with respect to the front surface of the furniture frame, or the orientation of the front panel of the plurality of drawers are not parallel to each other and are not aligned. In order to improve the appearance (in order to avoid the front panel in a state of having a step and arranged in a scale shape), it is a drawer rail that can adjust the inclination of the front panel, and is compact and stable. A length adjusting mechanism having a simple structure is provided.
