Description

Railing strut for a drawer

The present invention relates to a railing strut for a drawer, wherein the railing strut has at least one end region for connection to a wall element of the drawer, wherein the rail strut has at least one end region a locking device with at least one locking element, which engages to lock the rail strut with the wall element can be brought, wherein the rail strut in addition to at least one locking element has at least one movably mounted actuating element, wherein the at least one locking element is movable by applying force to the actuating element in a release position, in which in a locked state with the wall element of the rail strut locking between the rail strut and the wall element is detachable.

Furthermore, the invention relates to an arrangement with at least one rail strut of the type to be described and with at least one wall element, in particular a front panel or a rear wall, a drawer, wherein the end portion of the rail strut by the locking device with the wall element is detachably connectable.

Furthermore, the invention relates to a drawer with at least one rail strut of the type to be described and a method for mounting and dismounting a railing strut on a drawer.

Railing struts are used to increase the receiving volume of a drawer, for stiffening the drawer and in a length-adjustable training for tilt adjustment of drawer front panels. Typically, the rail struts are positioned at a predetermined distance above the drawer side walls, with the longitudinal direction of the rail strut being substantially parallel to the longitudinal direction of the drawer side wall.

An example of a rail strut is shown in EP 2 323 518 B1 of the Applicant. The rear end portion of the rail strut is via a snap connection element with connectable to the rear wall of the drawer. The snap connection element may comprise one or more plastic bottles, which engage in a locked state of the rail strut in corresponding openings of the rear wall. The disadvantage of this is that disassembly of the rail strut of the rear wall is relatively difficult and only with great effort to perform.

In the US 2007/159039 A1 a drawer with a railing strut is shown, which is provided in a rear end region with a clip for releasable connection to a drawer rear wall. The clip has a spring-trained web with a flap arranged thereon, which engages in the assembly of the rail strut in a corresponding receiving opening of the rear wall. To release the lock a screwdriver is inserted into an access opening of the rear wall, so that the lock between the tab and the receiving opening of the drawer rear wall is detachable. By lifting the resilient web by means of the screwdriver, the flap can be moved against its resilient action from the receiving opening of the rear wall, whereby the rail strut is separable from the drawer rear wall. The disadvantage of this is that the view is limited to the cloth and the accessibility to the cloth is difficult, with a tool is indispensable to release the lock.

Further releasable fastening possibilities of a railing strut on a drawer are shown in CN 2627916 Y, in WO 2017/001610 A1, in DE 10 2009 025 792 A1 and in EP 0 723 752 A2.

Object of the present invention is therefore to provide a rail strut of the type mentioned above while avoiding the disadvantages discussed above.

This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention it is provided that the at least one actuating element in a locked state with the wall element of the railing strut for a user for manual operation is accessible and directly operable, so that the lock between the rail strut and the wall element by the manual operation of the actuating element is releasable.

In other words, the rail strut has at least one movably mounted actuating element, by means of which the locking between the rail strut and a wall element of the drawer can be released on the wall element in an assembled state of the rail strut. The actuating element of the rail strut located in the mounting position is accessible to a user and directly operable, so that a comfortable disassembly of the rail strut (for example, for cleaning purposes) is made possible.

The actuating element may be formed separately from the at least one locking element. Alternatively, it is possible that the actuating element and the at least one locking element are formed on a common component, but as clearly distinguishable from each other components. According to one embodiment, the actuating element and the locking element are coupled to each other in motion, so that a corresponding application of force to the actuating element leads to a (non-destructive) movement of the locking element into the release position.

The actuating element may be displaceably mounted on the rail strut, preferably in a longitudinal direction of the rail strut, and / or may be tiltable or bendable about an axis which preferably runs horizontally in the mounting position.

The actuating element can be movably arranged on an end face of the rail strut and / or on a lateral surface of the rail strut. For example, the actuating element with an end face of the rail strut and / or substantially flush with a lateral surface of the rail strut, so that an unintentional exertion of force on the actuating element prevented and an attractive visual appearance is given.

The actuating element is designed for manual operation, wherein the actuating element may be provided with a friction-increasing corrugation. The at least one end region of the rail strut can have at least two locking elements, wherein the at least two locking elements can be moved into the release position together by exerting force on the actuating element. By the arrangement of two or more locking elements, which are movable by exerting force on the actuating element in a releasing the wall element release position, a particularly tamper-proof connection between the rail strut and the wall element and a comfortable unlocking of the locking elements from the wall element of the drawer brought about in the locked state become.

The railing strut can be connected directly to a wall element of the drawer, for example by a pin arranged on the rail strut, which can be inserted in a bore of the wall element and thus held in position. Alternatively, it is possible that the rail strut is connected to the wall element via at least one furniture fitting arranged or formed on the wall element.

Further details and advantages of the invention will become apparent from the following description of the figures. It shows or shows:

Fig. 1 shows a perspective view of a piece of furniture 1 with a furniture body 2 and drawers 3, which are mounted on Schubladenausziehführungen 4 relative to the furniture body 2 movable. The drawer pull-out guides 4 have a cabinet rail 5 to be fastened by fastening sections 6a, 6b to the furniture body 2 and at least one drawer rail 8 to be connected to the drawer 3, which is movably mounted relative to the cabinet rail 5. To realize a full extension of the drawer 3, an additional middle rail 7 may be provided, which is movably mounted between the carcass rail 5 and the drawer rail 8. The drawers 3 each have wall elements 9 and 11 (preferably in the form of a front panel 9a and a rear wall 11a), a drawer bottom 10 and a drawer side wall 12, which is connected to the drawer rail 8 of the drawer extension guide 4 or detachably connectable. In addition, at least one rail strut 13 is provided, which extends at least over a partial area between the front panel 9a and the rear wall 11 a and which is arranged at a predetermined distance above the drawer side wall 12 and the longitudinal direction (L) in an assembled state substantially parallel to the drawer side wall 12 extends. At least one second decorative plate 14b (FIG. 2b) can be arranged between the drawer side wall 12 and the railing strut 13.

Fig. 2a-2c show the mounting of the railing strut 13 on the drawer 3 in time sequences. The drawer 3 comprises a first wall element 9 and a further wall element 3a for receiving a first decorative plate 14a, which - like the second decorative plate 14b - can be made of glass, stone, wood, plastic or metal. On the first wall element 9 a furniture fitting 15 is arranged or formed in the form of a connecting pin, which is connectable to a first end portion of the rail strut 13. In the exemplary embodiment shown, the first end region of the railing strut 13 has a cavity 18 for receiving the furniture fitting 15. At the second end region of the rail strut 13, a recess 16 is arranged, which is formed in a plan view substantially rectangular or L-shaped and which is provided in the assembled state of the rail strut 13 for partially receiving the second wall element 11. The railing strut 13 is provided with a support member 17, which in a, preferably horizontally extending, opening 19 of the second wall element 11 can be inserted. In the recess 16 of the railing strut 13 at least one movably mounted locking element 23 a is arranged, which with a first recess 20 of the second wall element 11 is lockable. By an actuating element 21 in a mounted state of the rail strut 13, the lock between the rail strut 13 and the second wall element 11 is releasable. An imaginary connecting line 22 (FIG. 2 b) is arranged normal to the first and second wall elements 9, 11.

For mounting the railing strut 13, the procedure is as follows:

the rail strut 13 is brought with a first end area in connection with the first wall element 9 or with the furniture fitting 15 mounted on the first wall element 9 (FIG. 2b), the rail strut 13 being opposite the imaginary connecting line 22 which is normal to the wall elements 9, 11 is located, includes an acute angle,

- The acute angle is reduced by pivoting the rail strut 13 relative to the imaginary connecting line 22 (Fig. 2c) until the rail strut 13 is aligned substantially parallel to the imaginary connecting line 22, wherein it is preferably provided that the support member 17 of the rail strut 13 in the Opening 19 of the second wall element 11 is inserted,

- The railing strut 13 is then manually tilted about an axis extending in the longitudinal direction (L) of the rail strut until the at least one locking element 23a of the rail strut 13 is locked to the second wall element 11, wherein it is preferably provided that the at least one locking element 23a in a first recess 20 of the second wall element 11 engages.

The disassembly of the rail strut 13 from the second wall element 11 is effected in that the actuating element 21 is moved by exerting force (for example, by applying pressure to the actuating element 21 in the longitudinal direction (L) of the rail strut 13) in a release position in which the lock between the rail struts 13 and the wall element 11 or mounted on the wall element 9 furniture fitting 15 is solved.

Fig. 3a shows the rear end portion of the drawer 3 in a perspective and partially broken view from above. In the exemplary embodiment shown, the rail strut 13 has at least two movably mounted locking elements 23a, 23b on, wherein the first locking element 23a with the first recess 20 of the wall element 11 and the second locking element 23b with a second recess 20a of the wall element 11 are releasably lockable. The imaginary longitudinal axes of the recesses 20, 20a of the wall element 11 can thereby run at right angles to each other, whereby a particularly tilt-proof connection between the rail strut 13 and the wall element 11 is made possible. The locking elements 23a, 23b are biased by at least one spring element 24, wherein the locking elements 23a, 23b by force exerted on the actuating element 21 against the force of the spring element 24 is movable together in the release position. The spring element 24 is formed here by a resilient plastic part, which is supported on a stationary stop 25 of the rail strut 13. As a spring element 24 and mechanical spring elements such as compression springs, tension springs or torsion springs can be used.

The rail strut 13 is pre-positioned on the wall element 11 by the rail strut 13 is pushed with its front end on the furniture fitting 15 and the support member 17 of the rear end portion is inserted into the opening 19 of the wall element 11. The prepositioned position of the rail strut 13 is shown in Fig. 3a. By subsequent manual tilting of the railing strut 13 about an axis extending in the longitudinal direction (L), the locking elements 23a, 23b are moved against the force of the spring element 24, whereupon the two locking elements 23a, 23b engage in the recesses 20, 20a of the wall element 11, preferably engage (Fig. 3b). In this way, the railing strut 13 is arranged in the longitudinal direction (L) relative to the drawer 3 clearance and also made a particularly non-tilt connection between the rail strut 13 and the wall element 11, because the rail strut 13 with the at least one end portion at three different positions on the wall element 11 is fixed (support member 17 in opening 19, first locking element 23a in the first recess 20, second locking element 23b in the second recess 20a of the wall element 11). By applying force to the actuating element 21 in the longitudinal direction (L), the locking between the locking elements 23a, 23b and the recesses 20, 20a of the wall element 11 can be released again (FIG. 3c), wherein the spring element 24 in FIG. 3c is maximally compressed. As shown in FIGS. 3a-3c, For example, the spring element 24, the locking elements 23a, 23b and the actuating element 21 may be integrally formed together.

Preferably, it can be provided that the first locking element 23a and / or the second locking element 23b is or can be moved by exerting force on the actuating element 21 in a longitudinal direction (L) of the railing strut 13).

Fig. 4a shows the rail strut 13 in an exploded view, wherein at both end portions of the rail strut 13 a movably mounted actuating element 21, 21 a for releasing the lock between the front wall element 9 (for example, with the furniture fitting arranged on the wall element 15) and the rear wall element eleventh is provided. The provided for pre-positioning of the railing strut 13 support member 17 is formed in the form of a tab on a bearing part 30, wherein the support member 17 is inserted into the opening 19 of the wall element 11. The common structural unit, consisting of spring element 24, the locking elements 23a, 23b and the actuating element 21 is mounted in the mounting position relative to the bearing member 30 in the longitudinal direction (L) of the rail strut 13 slidably.

At the front end portion of the railing strut 13 is a, preferably in the longitudinal direction (L) resiliently formed, length compensation element 26 is arranged, which serves, in the locked state of the rail strut 13 with the wall elements 9, 11 a between the front end of the rail strut 13 and the wall element. 9 cover occurring gap. The cavity 18 for receiving the furniture fitting 15 is formed in a receiving part 31, wherein the furniture fitting 15 by means of movably mounted locking elements 23c, 23d of the receiving part 31 is releasably locked. The head part 33 (FIG. 4b) of the furniture fitting 15 can in fact be releasably locked to the locking elements 23c, 23d and to a locking element 23e connected to the second actuating element 21a. In the illustrated embodiment, the second actuating element 21 a on a lateral surface of the rail strut 13 (for example, on the underside 29 of the rail strut 13) is arranged, wherein the second actuator 21 a is mounted tiltable or bendable about an axis horizontally extending in mounting position 27. With the actuating element 21 a inclined surfaces 28a, 28b are connected, which in a movement of the second Actuator 21 a about the axis 27, the locking elements 23c, 23d of the receiving part 31 elastically expand, whereby the furniture fitting 15 (and thus the wall element 9) of the locking elements 23c, 23d, 23e is released.

4b shows a cross section of the front wall element 9, wherein the rail strut 13 is locked with the furniture fitting 15 arranged on the wall element 9. The furniture fitting 15 may have a dowel 32 for attachment to the wall member 9 and a head portion 33 spaced therefrom, which is locked with the locking elements 23 c, 23 d of the receiving part 31 and the locking element 23 e of the second actuating element 21 a. The second actuator 21 a is arranged on the underside 29 of the rail strut 13 and closes with the bottom 29 of the rail strut 13 substantially flush. The second actuator 21 a may, as shown in Figure 4b, be provided with a corrugation or with a tool holder. The second actuating element 21a is bendable or tiltable by applying pressure in a direction transverse to the longitudinal direction (L) extending about the axis 27, so that the locking elements 23c, 23d by the inclined surfaces 28a, 28b are expandable and thereby the head portion 33 of the furniture fitting 15 is releasable , Those portions of the head portion 33 and / or the locking member 23 e, which contact each other in a locked state, may have an inclined surface, whereby the head portion 33 by a movement of the second actuating member 21 a about the axis 27 from the front cavity 18 of the rail strut 13 actively ejected and thereby the disassembly of the railing strut 13 is done quickly and comfortably.

A particular advantage of the rail strut 13 is that it forms a prefabricated unit together with the locking device and that on the drawer 3, on which the rail strut 13 is to be mounted, for the purpose of locking no additional functional elements (with the exception of the opening 19 and the Recesses 20, 20a of the wall element 11) must be provided. If appropriate, the rail strut 13 can also be designed to be adjustable in length, which is possible for example by at least two mutually in the longitudinal direction (L) telescopically movable part struts of the rail strut 13.
