Description

DESCRIPTION

Sliding drawer side frame

The invention relates to a side frame for a sliding drawer.

From the state of the art a side frame with a locking device is known for a removable fixing of a piece of furniture in the form of a plate, in particular of a front panel on the side frame, the front panel having a support device, which can be removably engaged with the locking gear. Such a side frame is known from DE 102010 060722 A1. The connection hardware of this state of the art has proven its effectiveness in practice and is characterized in that a base section is mounted on or configured on a frame adapter of a side frame of a sliding drawer and that a Manually operable release lever is hinged to a locking lever and the base section and extends to a clearance on a frame adapter so that a user can manually actuate it in the clearance. However, there is a need for further optimization for use on relatively tall side frames and front panels.

Document DE 202009014 811 U1 describes a connecting fitting for removably connecting a first piece of furniture with a second piece of furniture. The furniture fitting has a receiving element and at least two fixing elements, the receiving element being assigned to a first piece of furniture and the at least two fixing elements being assigned to a second piece of furniture, or vice versa. The housing element has locking equipment for removably holding the at least two fastening elements, the at least two fastening elements can be locked together in the housing element. The locking device of the receiving element has at least two locking elements that are subjected to or are subject to an energy accumulator, preferably a spring, which can interlock with the fixing elements.

In document DE 202009014811 it is problematic that the actuation of the fixing device between the front panel and the side frame or the sliding drawer or the release of the lock of the connection between the front panel and the side frame respectively is only possible with an additional tool. , such as, for example, a screwdriver.

From DE 298 18651 U1 a fixing device is known for fixing a front panel to sliding drawer frames. The fixing device has a front panel and a part of the respective sliding drawer that connects the dowel piece. The dowel piece has one or more expansion dowels that can be inserted into assigned holes in the front panel, with expansion screws that can be inserted through an opening in the dowel piece into the associated expansion dowel and can be rotated around. the expansion plug respectively by means of an operating lever and thereby expand the expansion plug. Consequently, the actuation of the actuating lever is carried out without the aid of a tool "by hand". A disadvantage of DE 298 18651 U1 is that a geometrically suitable variant of the fastening device is stored for each frame or panel height and must be kept ready or in preparation for the assembly of a sliding drawer.

From document US 6,234,596 B1 a connecting fitting for upper sliding drawers is known, which can be connected in two places to a front panel, respectively a lever used in combination for locking and releasing being provided at opposite ends of a base body , which runs between the two levers. The disadvantage is that this connecting fitting requires a relatively long base body, connecting the two levers, that it is not suitable for a variety of sliding drawer heights and that it cannot be mounted on support equipment of various types, since it It itself has a kind of fixing pin that must be inserted into a hole in the front panel, which is not suitable for narrow front panels.

For technological background document WO 2012/169982 is still mentioned.

In view of the state of the art, the object of the invention is to improve the side frame described at the beginning in such a way that it can be used in a simple way even in tall sliding drawers.

The invention solves this object by the object of claim 1. Apart from that, the invention achieves the object of claim 12.

The two locking devices defined in claim 1 in each of the side frames are constructed with mirror symmetry to each other. Since, in the case of lower sliding drawers, locking devices designed with mirror symmetry are anyway provided for the right and left side frames, it is possible to provide these two locking devices on tall sliding drawers on each side once each. This avoids that for two side frames of a sliding drawer four different locking devices have to be produced together.

In an advantageous embodiment variant of the invention, both locking devices are in each case independently operable from one another by a separate release lever in each case, which can each be operated with a single hand. The need for a tool to release the lock is therefore advantageously eliminated.

In a further advantageous embodiment variant of the invention, the locking devices are arranged in a mutually oriented manner, so that their release lever can advantageously be released with one hand respectively on one side of the sliding drawer or of the locking devices of the a side frame. For this reason, the handling of the locking equipment of the connecting fittings is advantageously facilitated. Advantageously, a tool-free removal of the front panel is possible. However, a tool can also be used for disassembly.

According to a further variant embodiment of the invention, a handle may also be provided to simultaneously actuate the two release levers of the two locking devices. The handle can also be arranged so that no displacement or removal of the side frame is necessary. Advantageously, a tool-free removal of the front panel is possible.

Further refinements and developments which advantageously contribute to the compact construction are indicated in claims 9-11.

The invention is explained in more detail below by means of an embodiment with reference to the drawings. They show:

In FIG. 1 a drawer cabinet 2 is represented. The drawer cabinet 2 has a cabinet body 3. In the cabinet 3 there are inserted in this case (in a purely exemplary manner) three sliding drawers 4, 5. The drawers The sliding drawers 4, 5 are guided in a displaceable manner in the furniture body 3, so that each of the sliding drawers 4, 5 is respectively pulled out of the furniture body 3 in an open position and can be pushed back from this into a closed position .

The sliding drawer 5 illustrated in Figures 2a and b has a first plate-shaped piece of furniture, which is preferably configured as a front panel 6 (in this case, a relatively tall front panel 6). The sliding drawer 5 has at least one second piece of furniture in the form of a plate, which forms one of the two side frames 1a, 1b of the sliding drawer 5. In the following example, the sliding drawer 5 is described with two side frames 1a, 1 B. The side frames 1a, 1b are preferably constructed in each case with two housings. In this connection, an outer casing 11a, 11b is displaceably guided in an inner casing 10a, 10b and the inner casing 10a, 10b forms a narrow cavity with the outer casing 11a, 11b respectively. Furthermore, the sliding drawer 5 still has a rear wall as well as a sliding drawer bottom 12. Preferably, but not necessarily, the outer casing and the inner casing consist of aluminum. According to a particularly preferred configuration, the outer casing and the inner casing are designed as extruded profiles of aluminum. Furthermore, it is preferred that the outer casing and the inner casing form a very narrow side frame. which is preferably narrower than 15mm, in particular narrower than 12mm. The invention can be used to advantage precisely in the case of such narrow side frames.

In Figure 2b the outer casing 11b of the left side frame 1b is not represented, seen from the operator of the sliding drawer 5, of the sliding drawer 5 and the inner casing 10a of the right side frame 1a is not represented, seen from the operator of the drawer sliding 5.

Each of the side frames 1a or 1b respectively has two connecting fittings 7a, 7b, with which the front panel 6 can be respectively attached to the side frame.

For this, the front panel 6 can be connected or is connected in the assembled state by connection fitting 7a, 7b via a support device 8 respectively to a corresponding locking device 9a, 9b on the corresponding side frame 1a or 1b.

The locking device 9a, 9b of the connecting fitting 7a, 7b can be fixed in different ways to the side frame 1a, 1b of the sliding drawer 5. In the case of double-walled side frames 1a, 1b, performs a fixation of a respective base plate 18 of the locking device 9a, 9b preferably in the inner casing 10a, 10b of the side frame 1a, 1b preferably through a shaping process, more preferably through a press-fit assembly with perforation prior or through clinching with prior drilling. As an alternative, other reversible and irreversible fixing possibilities are also conceivable.

In the context of the present invention, the structure of the support equipment 8 can be realized in different ways. It must be capable of being fixed or fixed to the first piece of furniture in the form of a plate, for example the front panel 6, and have a buttress element, for example a suitable recess or a plug 14 extending horizontally in the position of installation. The support kit 8 can be fixed (by clamping and / or adhesive), for example, with one or more dowel-shaped plug sections (not shown here) in openings in the front panel 6. Alternatively, It would also be conceivable to fix the support kit 8 to the front panel 6 in other ways, thus, by means of screws (see for this Figure 5d).

In Figure 5a, the sliding drawer 5 is shown with the front panel 6 mounted or locked and the outer casing 11b of the side frame 1b pushed back. The locking device 9a, 9b is therefore respectively in a locking position. The locking device 9a, 9b each have a release lever 22. The release lever 22 is therefore also in the locking position.

In Figure 5b, the sliding drawer 5 is shown with the front panel 6 still locked and the outer casing 11b of the side frame 1b pushed back. Accordingly, the respective release levers 22 of the locking equipment 9a, 9b moved in the direction of the release position.

In Figure 5b, the sliding drawer 5 is represented with the front panel 6 more released from the side frames 1a, 1b and the outer casing 11b of the side frame 1b pushed back. Accordingly, the respective release levers 22 of the locking equipment 9a, 9b moved further in the direction of the release position. In Figure 5d, the sliding drawer 5 is shown with the front panel 6 partially released and the outer casing of the side frame 1b pushed back. Consequently, the respective release levers 22 of the locking device 9a, 9b are in a release position, so that the front panel 6 can be detached from the sliding drawer 5.

In this connection, it is advantageously provided that each of the side frames 1a, 1b respectively has a second locking device 9b in addition to the first locking device 9a, this second locking device 9b being arranged and / or configured with mirror symmetry by above the first locking device 9a in the inner casing 10a, 10b of the side frame 1a, 1b and being arranged in the cavity between the inner casing 10a, 10b and the outer casing 11a, 11b of the side frame 1a and 1b.

By the term "with mirror symmetry" it is preferably understood in this case that the first locking device 9a is reflected perpendicularly to a plane of symmetry (which runs through the XY line and preferably in this case longitudinally through the center of the drawer sliding or otherwise perpendicular to the side frame 1a, 1b; see Figure 3), so that the resulting reflected image coincides with the position and location of the second locking equipment 9b. The locking devices are constructed in particular in such a way that the lower locking device of the left side frame is constructed identically to the upper locking device of the right side frame and vice versa. This is represented in Figure 2b, Figure 3 and Figure 4 as well as in Figures 5a to 5d so that in each case it can be clearly recognized.

Advantageously, both locking devices 9a, 9b can in each case be actuated independently of each other by the respective separate release lever 22, which in each case can be actuated manually by a user. In this regard, the distance of the release levers 22 from each other is preferably selected from so that both release levers 22 can be operated simultaneously with different fingers of one hand.

By using two locking devices 9a, 9b in different positions / orientations, a front panel fixing can be realized simply, inexpensively and thus advantageously even in the case of tall front panels 6. An arrangement of various construction height variants of locking devices 9a, 9b is thereby advantageously eliminated.

In Figure 2b, Figure 3 or Figure 4 as well as in Figures 5a to 5d it is represented in such a way that in each case it can be clearly recognized that the locking devices 9a, 9b are respectively arranged in a mutually oriented manner in the respective side frames 1a or 1b, so that their release levers 22 can be advantageously released with one hand respectively on one side of the sliding drawer 5 or the locking devices 9a, 9b of the side frames 1a or 1b. As a result, the handling of the locking devices 9a, 9b of the connecting fittings 7a, 7b is advantageously facilitated. Advantageously, a tool-free removal of the front panel 6 is possible.

Alternatively, a handle may also be present (in this case, not shown), to simultaneously actuate both release levers 22 of both locking devices 9a, 9b. The handle can also be arranged so that a displacement or removal of the outer casing 11a, 11b from the side frame 1a, 1b is not necessary. Advantageously, a completely tool-free disassembly of the front panel 6 is possible in such a way.

The structure of the preferred locking device of particularly compact construction will now be described by means of Figures 6a to 6d.

The locking device 9a has a spring-loaded locking lever 17 movably articulated, movable on a base plate 18 from a release position to a locking position.

The locking lever 17 is in the mounted state of the locking device 9a or 9b or of the side frame 1a, 1b, preferably always completely within a side frame 1a, 1b, so that no part of the locking device 9a extends towards the front panel 6. In Figures 5a to 5d, the sliding drawer 5 is respectively shown with the outer casing 11b of the side frame 1b pushed back. By simple and thus advantageous displacement of the outer casing 11a, 11b of the side frame 1b or 1a, the locking devices 9a or 9b are advantageously hidden from the outside in the locking position of the locking device 9a or 9b or when the front panel 6 is mounted.

The locking lever 17 represented in a way that can be clearly recognized in Figure 6a, 6b and, in particular, in Figure 6d, has a hook-shaped section 29, which is configured to engage behind a buttress or pin 14 on the support piece or on the support device 8 in the locking position of the locking device 9a. Apart from that, the locking lever 17 is pivotably or rotatably positioned relative to the base plate 18 on a bolt 27. The locking lever 17 further has a slide 28.

Mounting contours 19, 20, preferably hooks, are formed on the base plate 18 of the locking device 9a and on the locking lever 17, on which a spring is mounted, in this case a helical spring 21, with its ends that can form mounting eyelets. In such a way, the coil spring 21 pulls the locking lever 17 into an upper locking position. In the upper locking position, the hook-shaped section 29 of the locking lever 17 engages from behind in the front panel mounted state a buttress on the support piece or on the support equipment 8, whereby the One plate-shaped component is attached to the second plate-shaped component, thus, in this case, the front panel 6 in a side frame 1a or 1b. In such a way, the front panel 6 is removably fixed on the side frames 1a, 1b.

The base plate 18 has a cantilever 30 (or a step) that extends over the entire longitudinal extension of the base plate 18, which, in combination with a passage 31, forms a constructive space to house the helical spring 21. Apart from that , the base plate 18 has on its two longitudinal edges 32a, 32b several notches 33, which serve in the case of a process of shaping the inner casing 10a, 10b of the lateral frame 1a or 1b, to fix the locking device 9a or 9b to this.

Apart from that, the base plate 18 has a keyhole-shaped recess 34, which is geometrically designed in such a way that it can accommodate the buttress or the pin 14 in the support piece or in the support device 8 or correspond to the buttress or with the pin in the support piece or in the support device 8. This recess 34 simply prevents that, after releasing the locking device 9a, 9b, the front panel 6 may fall. Therefore, it is ensured that the front panel 6 can be released manually simultaneously, without tools and without risk on both sides.

Apart from that, the base plate 18 has a slide 35, which, in the assembled state of the locking device 9a or 9b, is pierced by a bolt 36, which simultaneously also pierces the slide 28 of the locking lever 17 and the release lever 22. Thereby, release lever 22 is in operative connection with release lever. lock 17.

The release lever 22 is preferably L-shaped in a side view. It has a lever arm 23 and a release arm 24, which is oriented angularly, in this case almost at a right angle, to the lever arm. 23. Apart from that, the release arm 24 is configured in a staggered manner perpendicular to the side view (see also Figure 6a and Figure 6d). Between the lever arm 23 and the release arm 24, a control surface 25 is arranged at the angle included by these arms, which is arranged almost perpendicularly in the open position of the locking device 9a. The release lever 22 is rotatably positioned by a bolt 37 on the base plate 18. In this regard, the release lever 22 may advantageously be elastically pre-tensioned in the locked position, so that inadvertent release of the release lever 22 from the locked position. Furthermore, the release lever 22 can also be elastically pre-stressed in the release position, in order to support an insertion of the support device 8 into the locking device 9a, 9b of the side frame 1a, 1b.

On latching, that is, on inserting the support gear 8, the release lever 22 on the control surface 25 is actuated by the pin 14 and the bolt 36 is thereby moved over the neutral location of the slide. 28. Therefore, the locking lever 17 is released and pivots upwards by the force of the helical spring 29, the pin 14 engaging behind the hook section 29 of the locking lever 17. Therefore, the equipment lock 9a, 9b is locked and thus the front panel 6 is removably fixed on the side frames 1a, 1b.

The locking device 9b is configured and arranged like the locking device 9a, but with mirror symmetry with respect to it.
