Description

connecting fitting

The invention relates to a Verbindungsbeschiag for releasably securing a plate-shaped furniture part, in particular a front panel, at an angle, preferably at right angles, aligned further ptattenför- shaped furniture part, in particular a side wall frame of a drawer, according to the preamble of claim 1.

A generic connection fitting is the subject of unpublished DE 10 2010 060 722.

The object of the present invention is to further improve a connection fitting of the generic type.

This object is achieved in that the release lever is constantly loaded by a force accumulator in the direction of the locking position.

By this measure it is achieved that accidental loosening of the connection fitting is reliably avoided, in particular acting on the connection fitting shocks or shocks can not lead to a repeal of the locking position.

By a spring, the release lever can always be brought in non-actuation in the locked position to the plant.

Of course, other measures instead of the spring are possible, e.g. to apply the release lever in the locking position by a permanent magnet. The permanent magnet can act on a ferromagnetic projection of the release lever in the locked position with its force field.

According to a development of the invention, it is provided that the spring is designed as a leg spring, which is supported with one of its legs on the upper side of the mounting base section and engages with its other leg the loosening lever on its underside facing away from the upper side of the mounting base section. Due to this installation position, the spring securing the locking position, in this case the leg spring, is secured against unauthorized unhooking or disassembly due to its inaccessibility due to the installation situation of the connection cover, for example, in a side wall frame of a drawer, so that no deliberate manipulation can lead to a cancellation of the locking position.

Preferably, the spring, in particular the leg spring, made of metal, preferably made of spring steel.

This results in a high expected life, so that the securing of the locking position of the connection fitting is practically permanently ensured.

Further features of the invention are the subject of further subclaims.

An embodiment of the invention is illustrated in the accompanying drawings and will be described in more detail below.

Hand force to reach the release position, wherein the release lever has been partially broken away to illustrate the position of the pin in the scenes.

Each connecting fitting, as shown clearly in FIG. 1, has two corresponding functional units which can be brought into engagement with one another, namely a carrying device 2 and a locking device 3 which can be brought into releasable engagement with the carrying device 2.

The carrying device 2 is fixed to a first plate-shaped furniture part, which (see FIGS. 3 to 5) is preferably designed as a front panel 4 of a drawer 5. This drawer 5 can be inserted into a furniture body 6 of a piece of furniture 7 in which it is displaceably guided so that it can be pulled out of the furniture body 6 into an open position and pushed out of it into a closed position (see FIGS. 3 and 4).

The locking device 3 (standing figures 2 and 6 and 7 and 8), however, is designed to be attached to a second plate-shaped furniture part, which is preferably formed as a side frame 8 of the drawer 5. The plate shape of the side frame 8 is realized here by a metallic double-wall cover 9, which is placed over one or more Zargenadapter 10 and, in a conventional manner, on the one or Zargenadaptern 10 can be locked, for example with mounting means such

Screws or locking means or the like. The Zargenadapter 10 also serve to receive a drawer bottom 1 (Figure 6) to the mounting contours 12 (Figure 2) and for placement on a rail construction, not shown here, with which the drawer is guided on the furniture body displaceable.

Each drawer 5 preferably has two of the side frames 8 and two of the connection fittings 1, so that the front panel 4 in two areas via one of the support means 2 with the corresponding Arretiereinrichtun- gene 3 at the corresponding two side frames 8 is connectable or in the mounted state connected is.

The construction of the carrying device 2 is largely arbitrary within the scope of the present invention. However, it must, at least on the first plate-shaped furniture part, for example the front panel 4, be fixable and have an abutment element, for example a suitable recess or a horizontally extending pin 13 in the installed position.

The locking device 3 has a base unit (see also FIG. 2), preferably a base angle 14, which is fixed to a leg (sections 15a, b) on an upper mounting surface 16 of the frame adapter 10 in the installed position, for example by welding. This fixing could also be done by other connecting means such as screws, furthermore, the base unit could also be integrally integrated in the frame adapter 10 (not shown here in each case).

It should be noted at this point that terms such as "top" and "bottom" are not generally to be understood as limiting. Rather, they relate to the usual installation and construction position of a piece of furniture, as shown in Figure 3.

The leg (Figure 2) is here divided into two leg portions 15a, b, between which there is a clearance to from the mounting surface 16 upwards To allow projecting contours of other, not further explained here functional elements.

The mounting surface 16 has in the front part, i. in the direction of the carrier device 2, an opening 17, through which functional elements of the locking device 3 to be explained still protrude into the frame adapter 0.

The frame adapter 10 has in a view perpendicular to the front panel plane substantially a U-shaped cross-section. Preferably, it is bent from a sheet metal, wherein the mounting surface 16 is formed by the shorter leg of the U-shaped cross section. In addition, the mounting contours 12 of the frame adapter 10 are in front of the drawer bottom 11. Between the two longer legs 18, 19 of the Zargenadapters a free space 20 is formed. This free space 20 is dimensioned such that a user can reach into it from below with his fingers.

The leg portions 15a, b have a mounting base portion 21 extending perpendicular to the mounting surface 16. On the mounting base portion 21, a locking lever 22 is articulated movably, which is movable from a release position to a locking position.

The locking lever 22 is preferably always completely within the side frame 8, so that no part of the locking device 3 extends into the front panel 4.

The locking lever 22 has a hook portion 23, which serves to engage behind the corresponding abutment, preferably a pin 13 on the support means 2. The locking lever 22 is designed as a lever mounted on one side. Its pivot bearing 24 is preferably located on its side facing away from the front panel 4 side. The locking lever 22 is preferably penetrated in this area at an opening 45 by a pin 25, which preferably passes through a slot-like opening 26 in the mounting base portion 21.

The opening 26 has a dimension that is significantly larger than the diameter of the pin 25 at least in the X direction, so that the pin 25 passes through the opening 26 with play.

At the mounting base portion 21 and the locking lever 22 mounting contours 27, 49 are formed as hooks on which a spring, here a Schraubenfe- 28, with their ends, which can form mounting arches, is mounted. The coil spring 28 is almost horizontal. Its one end is fixed in the mounted position preferably above the opening 26 in a recess 46 of the mounting base portion 21 and its other end is preferably located approximately midway between the pin 25 and the hook portion 23.

Thus, the coil spring 28 pulls the locking lever 22 in an upper locking position, in which when the hook-shaped portion engages behind the abutment on the support member or on the support means 2, which is a plate-shaped component is fixed to the other, so here the front panel. 4 on the one side frame 8.

Due to the mounting of the pin 25 on the rear reveal of the preferably slot-like opening 26, with play in the opening 26, the end of the locking lever 22 with the pin in the opening 26 can move something, especially in the direction parallel to the side frame 8 and perpendicular to the front panel 4.

This is particularly advantageous because it is prevented by the action described that hard shocks are forwarded to the front panel immediately with full impulse to the side frame 8. The shock pulse is rather removed by the interaction of the bearing clearance of the pivot bearing 24 and the spring 28 kinetic energy. Thus, the connection fitting 1 according to the invention significantly reduces the risk of damage to the side frame construction and the fastening of the front panel 4 with the pin sections 42, 43 of the support device 2 of the connection fitting 1 in a simple manner.

It is advantageous if the play in the pivot bearing 24 in at least one rieh- direction, preferably in the mounting direction or here the "X direction" (Figure 1) in the range of 0.3 to 3 mm, particularly preferably in the range of 0, The groove can be formed at the opening 26 and / or in the connection area between the pin 25 and the locking lever 22, for example at the opening 45.

To release the locking lever 22 from the connecting position, as shown in FIG. 1, a release lever 29 integrated in the locking device 3 is used. The release lever 29 preferably has an L-shape in a side view. It has a lever arm 30 and a release arm 31 which is aligned at an angle, here almost at right angles, to the lever arm 30. The release arm 31 is further formed in a view perpendicular to the side view (see also Figure 2) here in a stepped manner. Between the lever arm 30 and the release arm 31, in the enclosed by these arms angle, a control surface 51 is arranged, which is arranged almost vertically in the open position of the locking device 3. The lever arm 30 is advantageous here with its end to the mounting base portion 21, preferably to the front panel 4 and the support means 2 near the hook portion 23 by means of a pin 32, the corresponding openings 34 and 36 in the release lever 29 and in the Mounting base portion 21 in the material doubling 37 passes through, articulated. The material doubling 37 extends to the side on which the locking lever 22 is arranged in order to preclude a collision of the hook section 23 engaging in the carrying device 2 with the components in the carrying device 2 which are not explained here. In the mounting base portion 21, an arcuate gate 44 is formed, which is in an overlap with an angular gate 50 in the locking lever 22 so that the pin 33 both scenes 44, 50 passes through and in which the pin 33 is formed at a distance about its pivot point moved by the storage in the openings 34, 36, wherein an overpressable dead center is formed by the angular slide 50 and wherein the pin 33 is disposed in an opening 35 on the release lever 29. Further, a head 38 is formed on the pin 33, so that the locking lever 22 securely on

Mounting base portion 21 is guided in the slot 44 when the locking lever 22 moves between the open position and the locking position.

The slide 50 has, as shown particularly clearly in FIG. 2, a pocket 50a extending approximately in the direction of the upper edge of the locking lever 22 and a further pocket 50b extending in the direction of the front panel 4, approximately in the direction of the release arm 31. wherein the pin 33 engages in the locking position in the upwardly directed pocket 50a and in the release position in the approximately in the direction of the release arm 31 extending Ta- see 50b.

As FIGS. 2 and 15 in particular make clear, a spring 55, preferably a leg spring, is mounted on the pin 32, said spring being connected to one of its legs 55a on the mounting base section 21, preferably on the upper side. side of the mounting base portion 21 is supported and with its other leg 55b, the release lever 29 engages under the upper side of the mounting base portion 21 facing away underside, in particular in the region of the lever arm 30, which makes Figure 15 particularly clear. Thus, the release lever 29 is constantly loaded in the direction of the locking position and the pin 33 which is in the locking position in the upper pocket 50a of the link 50 is fixed non-positively by the force of the spring 55 in this locking position. The locking position can only be canceled by actuation, in particular by manual actuation of the release lever 29, but not by acting on the connection area shocks, loads or other external forces. Thus, a highly effective backup of the locking position is guaranteed.

Preferably, the spring 55 made of metal, in particular made of spring steel, and thus provides a prerequisite for an extremely long life, so that even in continuous operation damage or impairment of the above-described securing the locking position can not occur.

Due to the installation position, the spring 55 is practically inaccessible from the outside and can therefore not be removed or destroyed unrestrictedly.

The release arm 31 projects downwards through the opening 17 into the free space 20 and can be grasped there with a finger.

When locking, that is, when inserting the support means 2 in the locking device located in the open state 3 is actuated by the pin 13 of the release lever 29 on the control surface 51 and thus the pin 33 moves from the release position in the pocket 50b on the dead center of the gate 50 (see Figure 11). As a result, the locking lever 22 is released and pivots by the force of the coil spring 28 upwards, the pin 13 is engaged behind.

FIG. 7 also illustrates that the double-wall cover 9 can have a lateral opening 48 in order to allow lateral access to the diaphragm adjustment on the carrying device 2.

When the release arm 31 is pulled in the direction of the support device 2 or the front panel 4, the locking lever 22 is moved against the force of the spring 28 from the moved locking position and its upper position in an open position or lower position, preferably pulled (see Fig. 16).

Preferably, the locking and locking lever 22 by the pin 33 on the release lever 29 so far pivoted that a dead center in the gate 50 can be overcome, so that the locking lever 22 can remain after a corresponding movement in this position in an open position, which in particular facilitates the initial assembly, since in such a way the support means 2 with the front panel 4 is first brought into a mounting position in the locking device 3. By a sufficiently large force against the direction X on the front panel 4 then the support means 2 by means of the pin 13, the release lever 29 on the control surface 51 and thus the pin 33 move over the dead center of the gate 50, so that by the spring 28 of the locking lever 22 moves in its locking position, preferably pulled, in which the hook portion 23, the abutment - here the pin 13 - engages behind the support means 2.

Finally, it should be noted that the support means 2 preferably each with one or more dübeiartigen pin section {s) 42, 43 in openings of the Frontbiende 4 can be fixed (clamping and / or adhesive). Alternatively, it would also be conceivable to attach the carrying device 2 to a front panel 4 in another way, e.g. by means of screws (not shown here). This connection on the front panel 4 is significantly relieved by the device according to the invention described above and thus increases the service life of the furniture.

As an alternative to the leg spring 55 shown in the exemplary embodiments, the release lever 29 can of course also be permanently loaded in the direction of the locking position by other spring configurations (not shown here). LIST OF REFERENCE NUMBERS
