Description

The present invention relates to a drawer having a device for attaching a movable rail to a drawer slide, having a support that is located on a side panel on which a U-shaped holder is located, and the movable rail is configured to be inserted with a front end section into the U-shaped holder, and the movable rail is configured to be locked onto the support and/or holder by at least one latch that engages at least one hole on the movable rail, wherein the drawer has a front panel, and a method for installing the drawer on the movable retractable guide rail.

WO 2012/068594 discloses a docking device for attaching a drawer to a slide rail. The rail is secured to a latch portion which has a flexible spring tab to hold the rail in the locked position. To remove the lock, the latching part can be detached from the rail using a handle. The flexible spring tongue is reinforced with a stiffening rib to limit flexibility. However, in similar plastic components, the fluidity of the plastic may result in reduced joint holding forces.

Thus, the present invention is directed to provide a drawer having a device for securing a movable slide rail to a drawer, and a method for installing the drawer, which provide a reliable and stable connection between the rail and the drawer for a long period of time.

This problem is solved by a drawer having the features of clause 1 of the formula of the invention, and a method having the features of clause 12 of the formula of the invention.

A drawer according to the invention comprises a device for securing a movable slide rail with a U-shaped holder into which an end section of the rail can be inserted to be locked onto at least one latch. The holder rests indirectly or directly on the front panel on a supporting surface so that bending load can be absorbed by the holder, which increases the rigidity of the holder and dimensional stability. This ensures that the rail can be held stably in the U-shaped holder even over long periods of time.

The U-shaped holder preferably has a foldable tab on which a support surface is formed on a side facing the front panel. The U-shaped holder may have a slotted seat, the support surface being offset perpendicular to the longitudinal direction of the slotted seat, such that the application of force to the support surface results in a rotational movement of the bendable tab. Thus, the bendable tab can be pre-pressed by a force on the supporting surface in the direction of the slotted socket. The movable rail in the installation position is located in a slotted socket, which provides improved fixation of the rail in the holder.

In this case, the bendable tab can press and pinch the movable rail in the installation position, under pressure with a certain pre-pressure through the supporting surface into the installation position. The support surface need not be directly pressed against the front panel, but may be indirectly contacted by one or more additional interconnected components. In any case, the support is provided by a component that is firmly connected to the front panel. In this case, the front panel can be pre-pressed by at least one spring in the direction of the holder. Such a spring can be provided, for example, in the side panel of the front panel fixing device, by means of which the front panel is pre-pressed towards the side panel. The front panel can then press against the support surface to act on the holder, in particular the bendable tab of the holder.

According to the first variant, the latch for locking the movable rail can be made integral with the support, preferably on a bendable bridge. The latch may be formed by forming a protrusion that engages a hole in the rail for locking purposes. Alternatively or additionally, the latch may be located on a separate mounted pivot arm that is pre-pressed by a spring into the locked position. Such a lever can be mounted, for example, rotatably on a support.

The U-shaped holder has a surface on which a support surface is formed on a side facing the front panel relative to the installation position. This support surface projects from the holder toward the front side and may be subject to pressure from the front panel or a component connected to the front panel to pre-press the holder, in particular the bendable tab on the holder. The U-shaped holder with a bendable tab can be produced as a molded part made of plastic. The support is preferably made of a bent metal plate on which the holder is fixed.

If the rail has two longitudinally offset holes to lock the rail onto the latch, different mounting positions may be provided depending on the drawer front design and what holding forces the connection must withstand. The arrangement of the two longitudinally offset holes also allows the drawer to be pre-installed on the rail and then secured in the final installation position on the movable rail in a second installation step.

In the method according to the invention, a drawer is placed on two movable rails of two drawer guides in order to then slide the drawer along the movable rails, the front end section of each rail being inserted into a U-shaped holder on which the bendable tab is spread. The movable rail is then locked onto the movable rail as the drawer is further displaced, the support surface of the holder resting indirectly or directly on the front panel, and the bendable tab on the holder is pre-pressed towards the movable rail. In this way, during installation, support for the holder can be ensured and the connection between the drawer and the rail can be optimized.

FIGS. 15A to 15D show various schematic views of a modified sliding guide rail mounting apparatus.

The drawer 1 contains two side panels 2 and one front panel 3. As shown in Fig. 2, the bottom panel 4, on which the movable slide rail is attached, is located between the side panels 2.

As can be seen from the detailed view in Fig. 3, a holder 6 fixed to a support 5 is located under the bottom panel 4. The support 5 may be made of a bent metal plate and includes a latch 8 formed as a protrusion or convex and connected by a bendable jumpers with support 5. For this purpose, a slot 9 is provided, which gives flexibility to the bendable jumper 7, located in the longitudinal direction of the retractable guide rail.

In FIG. 4, the side panel 2 is shown uncovered, so that the means 4 for securing the front panel 3 are visible. The means a10 comprise two connecting parts 11, which can be fixed to the support 12 of the front panel 3. The front panel 3 is locked by means of the connecting parts 11 and the support 12, is pre-pressed by springs 13 towards the side panel 2. The front panel 3 presses against the side panel 2 here in the upper region and is pre-pressed in the lower region towards the supporting surface 14 of the holder 6. It can also be provided that the front panel 3 is attached only by one or more than two connecting parts 11 on the side panel 2.

FIGS. 5 and 6 show a bottom view of a drawer in which the holder 6 is shown under the bottom panel 4. The holder 6 includes a slotted seat 15 which extends parallel to the longitudinal direction of the drawer rail and is enclosed by a U-shaped holder 6. The slotted seat 15 is provided with a foldable tab 16 that is integrally formed with the holder 6. A support surface 14 that presses against the front panel 3 is formed on the bendable tab 16 on the side facing the front panel 3. It is also possible to provide additional components between the support surface 14 and the front panel 3, so that the supporting surface 14 on the front panel 3 is supported only indirectly through additional components.

The latch 8, which is located on the bendable jumper 7 of the support 5, is provided on the slotted socket 15 on the side opposite to the bendable tab 16. The latch 8 is provided in the area of the tip of the bendable tab 16.

The installation of the movable slide rail 20 is shown in FIGS. 7 and 8. The movable rail 20 includes two holes 21 and 22, which are offset in the longitudinal direction of the rail. The intermediate position during installation is shown in Figs. 7 and 8, in which the latch 8 is not blocked on either of the two holes 21 and 22. In this position, the bendable jumper 7 is deflected at the latch 8, which protrudes in relation to the rail 20 Thus, the rail 20 is pressed against the bendable tab 16, which is made of plastic and can be deformed. To avoid this, the bendable tab 16 is supported by a support surface 14 on the front panel 3, and the bendable tab 16 has a plurality of support ribs 60 that extend substantially perpendicular to the longitudinal direction of the rail 20. The support surface 14 is offset from the end of the rail 20 in the direction , perpendicular to the longitudinal direction of the rail 20, for example, by 4-40 mm.

The device for fastening the movable rail 20 of the retractable guide is shown without the rail 20 in Figs. 9 and 10. It can be seen that the latch 8 can be rotated on the bendable jumper 7, and the end section of the rail 20 can be inserted into the slotted socket 15. In the installation position, the latch 8 can be blocked in one of two holes 21 or 22.

In Fig. 11, the tab 16 is shown in its installation position. During installation, the tab 16 may be subject to a force that occurs, for example, when the rail 20 is locked on the latch 8, in particular if the latch 8 is not yet completely locked on the hole. A force is then applied to the tab 16 through the rail 20 and rotated clockwise as in FIG. 11. Thus, the slotted socket 15 is slightly moved apart.

In FIG. 12, the rail 20 is then locked onto the latch 8. A force F acts on the support surface 14 from the front panel 3, for example through a spring 13, by means of which the front panel 3 is pre-pressed towards the side panel 2. Thus, the bendable tab 16 is pre-pressed in the direction of the slotted socket 15, as shown by the force F in Fig. 12. In this case, the bendable tab 16 rotates counterclockwise, as shown by a comparison of FIGS. 11 and 12. The contact surfaces opposite each other on the slotted seat 15 are thus aligned substantially parallel.

In Fig. 13, the holder 6, having a slotted socket 15, is shown without a support 5 and without a movable rail 20. The holder 6 is made in the form of a molded part made of plastic and can be inserted as a strip section 61 into the side panel 2 and into the socket on the support 5. Bendable tab 16, which rests on the support surface 14 on the side facing the front panel 3, is formed integrally with the strip section 61 in the mold.

FIGS. 14A to 14D show schematically the installation of the movable slide rail 20 on the U-shaped holder 6.

In FIG. 14A, the rail 20 is positioned in front of the bendable tab 16 of the holder 6, and part of the wall of the rail 20 is pressed against the latch 8, which is rotated by the bendable bridge 7. If the rail 20 is moved further along the holder 6, as shown in FIG. 14B, the end section falls into the slotted slot 15 of the U-shaped holder 6. In this case, the latch 8 is locked on the hole 22 of the rail 20. In this locked position, the rail 20 is pre-installed on the U-shaped holder 6. This position can be used, for example, for transportation purposes.

The position is shown in Fig. 14C, where the rail 20 is inserted further into the slotted socket 15 of the holder 6. Due to contact with the entrance bevel on the latch 8, it is again deflected and pressed against the wall section of the rail 20, as shown by the arrow. The rail 20 is pressed in this position against the bendable tab 16, as shown by the second arrow. The bendable tab 16 rests on the support surface 14, which is pressed against the front panel 3.

Now the rail 20 can be inserted into the holder 6 until the latch 8 is locked on the second hole 21. Thus, the latch 8 is no longer pressed against the rail 20, and the bending tab 16 can rotate back, the rotation movement being supported by a force from the front panel 3 on the supporting surface 14.

In the installation sequence of Figs. 14A-14D, the latch 8 is made integral with the support 5, which is made of a bent metal plate. It is also possible to install a latch 8' on a pivot arm 7' which is rotatably mounted on a bearing 70. The arm 7' may be rotatably mounted on a holder 6 or a support 5. Installation of a modified rail mounting device 20 is shown in Fig. 15A- 15D.

In FIG. 15A, rail 20 is positioned next to bendable tab 16 and presses latch 8' on swing arm 7' against the force of spring 71. If rail 20 is now further inserted into slotted slot 15 on holder 6, as shown in FIG. 15B, latch 8 ' is locked at the first hole 22 of the rail 20. Thus, the lever 7' rotates around the bearing 70 under the action of the spring 71. This position can be used as a transport position.

In FIG. 15C, the rail 20 is further installed and moves towards the front panel 3, causing the arm 7' to rotate against the force of the spring 71. In this position, the spring 71 is pressed against the wall section of the rail 20, which then presses on the bendable tab 16, which can deform it. The bendable tab 16 rests here on the support surface 14, which is pressed against the front panel 3.

15D shows the mounting position of the rail 20 in which the latch 8' is locked on the second hole 21. Thus, the lever 7' is again rotated by the force of the spring 71, and the bendable tab 16 is rotated towards the slotted seat 15, this movement being assisted by the front panel 3 and supporting surface 14. Bendable tab 16 can press and pinch rail 2 here.

In the illustrated example embodiments, the rail 20 includes two openings 21 and 22 for locking a latch 8 or 8'. Of course, only one hole or more than two holes 21 and 22 can be provided.

The support surface 14 of the holder 6 rests directly on the front panel 3. Of course, it is also possible to provide additional components between the front panel 3 and the support surface 14.

In the illustrated example embodiments, the tab 16 is made integral with the holder 6. Of course, it is possible to manufacture the tab 16 separately, rotatably mounted on the holder 6 via an axis.
