Description

The invention relates to a multiple-locking device for a locking fitting according to the preamble of claim 1, a frame with such a locking device and a drawer.

The DE 10 2010 060 722 A1 discloses a locking fitting comprising a locking device having a force storage device, which is arranged on the frame and a corresponding connection fitting on a furniture plate, in particular on a front panel, which can be pulled with a catch lever on which the force accumulator acts on the front panel. Here, a manually operable release lever is provided.

For drawers with high sides come to improve the diaphragm seat two superimposed fasteners per frame used. Thus, it is known to realize an attachment of the panel with two superimposed on the panel connection fittings and two corresponding superimposed locking devices on the frame. The two locking devices thus form a double locking device and thus also a multiple locking device.

It is desirable to be able to solve the two locking devices or safety gear together in just a single unlocking operation to remove the panel from the frame. When locking is also to ensure that the locking devices only trigger when the corresponding connection fitting has reached the catch position, i. for each safety gear each separate triggering is necessary.

The creation of a compact locking fitting with such functionality is the object of the invention.

The invention solves this problem by the subject-matter of claims 1, 17 and 18.

• - einem ein- oder mehrstückigen Grundkörper,
• - an der ersten Arretiervorrichtung sind zumindest drei mindestens begrenzt bewegliche Haupt-Funktionselemente vorgesehen: ein Auslösehebel, ein Fanghebel, und ein Kraftspeicher,
• - an der zweiten Arretiervorrichtung sind zumindest drei mindestens begrenzt bewegliche Haupt-Funktionselemente vorgesehen: ein von einer Kraftspeichervorrichtung kraftbeaufschlagter Auslöseverhinderer, ein Fanghebel, und ein Kraftspeicher, und
• - ein Koppelhebel zum Koppeln der ersten Arretiervorrichtung mit der zweiten Arretiervorrichtung.

Claim 1 provides a multi-locking device comprising at least first and second locking devices for a frame, each designed to cooperate with a multiple connection fitting for a panel, having the following features:

• a single or multi-piece basic body,
• - At the first locking at least three at least limited movable main functional elements are provided: a release lever, a catch lever, and a power storage,
• - At the second locking at least three at least limited movable main functional elements are provided: a kraftbeaufschlagter of an energy storage device trip, a catch lever, and a power storage, and
• - A coupling lever for coupling the first locking device with the second locking device.

With the multi-locking device designed in this way, the functionality and properties required in the task can be excellently implemented, which in particular will also clarify the description of preferred exemplary embodiments. In this case, the two locking devices each have a first energy storage and the second locking device additionally a (further) force storage device which acts on the tripping preventing serves to prevent a triggering of the second power storage device in the open position.

It is advantageous for the realization of the required functionality when the release lever and the coupling lever can be brought into a common over-center position and from this solvable.

It is also advantageous if the force-loaded release lever is acted upon by a spring as an energy storage device directly or indirectly with force.

The main body may consist of one or more elements, which may be mutually adjustable, and at least partially plate-shaped, may exist. Advantageously, the elements of the base body may be formed as a base plate assembly having at least one base plate. The term "base plate" is not too narrow. This includes in any case sections of just trained facilities but also one or more struts, etc. In a version with two or more base plates may be present between them a slot. This can possibly be used advantageously for the safe arrangement of one or more functional elements.

The energy accumulator may consist of one or more spring elements and possibly connecting or deflecting elements, bolts or levers.

In terms of a compact design is also advantageous if the lower release lever is arranged on the one outer side of the base body and the lower catch lever on the other outer side or between two elements of the main body in a slot. Thus, these levers can move well without hindering each other in the movement. Preferably, the release lever is also rotatable on one end of the Stored energy storage, which is further guided displaceably in the slot of the body.

According to another embodiment of the energy storage can be designed as a spiral spring arrangement, since such a spiral spring arrangement provides particularly well the necessary spring force for actuation and particularly well, for example, in a frame can be accommodated.

It can be advantageously provided that the spiral spring arrangement comprises a V-shaped or U-shaped spiral spring with two arcuate longitudinal limbs, which are integrally or individually formed, wherein the longitudinal limbs are connected to each other in a one-piece configuration via a bend.

Then it is further advantageous in terms of compact design and good function, when the two arcuate longitudinal legs each have a bent end, which form the free ends of the spring assembly, which in force to be acted upon elements, in particular the main body, the release lever and the Catch lever, engage and enforce these preferably in whole or in part.

So that the spiral spring does not have to be designed too large, it is also advantageous if the spiral spring arrangement has a spring amplifier. The task of the spring core is to guide the spiral spring and to allow a very good preload, preferably a nearly maximum, bias of the spiral spring.

Structurally, this is easy to implement by the bending spring or its longitudinal limbs is at least partially placed around a spring core / are, which serves as a spring amplifier.

In terms of a compact construction of the spring arrangement is further advantageous if the spring core has a shape adapted to the shape of the bent longitudinal leg shape and ensures partial support of these longitudinal limbs over a portion of the length of these legs, especially in their sections that expand.

What is also provided is a frame for a drawer with a locking device according to one of the related claims and a drawer with a frame according to claim 17 and with a panel with a connection fitting which is attached to the locking device.

Further advantageous embodiments of the invention can be found in the dependent claims.

In 1 is a piece of furniture 1 with a furniture body 2 with side walls 3 shown. In the furniture body 2 are between the sidewalls 3 several here - purely exemplary three - drawers 4 . 5 . 6 set, by means of (not shown here) pullout guides relative to the furniture body 2 on the side walls 3 inside sliding, so that each of the drawers 4 . 5 . 6 each from the furniture body 2 can be pulled out in an open position and again pushed out of this into a closed position.

One or more of the drawers 4 . 5 and 6 show (see 1 and 2 in interaction) preferably a front panel 7a or 7b (here in two different vertical heights) on, two here parallel (side) frames 8 (of which in 2 one is shown), a back wall 9 and a floor 10 , The in 2 illustrated drawer 5 has the front panel 7a - here a vertically relatively flat front panel - on.

The frame 8th points (see 2 ) on a main extension direction X. This direction X is also the direction in which the drawer in the furniture body 3 retractable and extendable from this is. The after 1 this vertical direction is the direction Y - in the width of the frame 8th is measured - and the other in the usual installation position vertical direction the direction Z.

The frames 8th - please refer 2 and 3 - Are preferably constructed in each case double-shelled and have an inner shell 11 and an outer shell 12 on. The inner shell 11 includes with the outer shell 12 each a narrow cavity 13 , A single-shell construction with a corresponding cavity would also be conceivable.

Preferably - but not mandatory - are the outer shell 12 and the inner shell 11 from a metal, in particular steel sheets, or from a light metal, in particular aluminum or an aluminum alloy.

It is further preferred that the outer shell 12 and the inner shell 11 a very narrow frame 8th form, whose cavity 13 preferably narrower than 15 mm. Especially with such narrow frames 8th the invention to be explained below can be used advantageously.

The front panels 7a , b are each on the two sides 8th with at least one diaphragm lock fitting, consisting of a connection fitting attached to the front panel 15 and one on the frame 8th arranged and fastened locking device 14 , assembled and held ( 4 to 10 ).

In the 2 illustrated frame 8th Therefore, each of the in 4 ff or in the 11 ff pictured locking device 14 on, which is designed in each case, when attaching the front panel 7a or b to the frame 8th each the connection fitting 15 on the front panel 7a first to reach behind, then to the frame 8th to pull on and then at this firmly - but releasably - to keep locked. This is in the 6 to 10 shown in several consecutive steps.

Because the frame 8th In the Y-direction is designed relatively narrow and at least in variants also vertically relatively flat, it is necessary, a correspondingly compact designed but still safe and well-functioning locking device 14 to accomplish.

This is done with the locking device to be described below 14 implemented, which is designed to the connection fitting 15 behind and behind the frame 8th to secure.

First, let's briefly the connection fitting 15 considered. The connection fitting 15 has a diaphragm carrier 16 - please refer 5 and 6 - On, with one or more fasteners (not shown here) as screws on the frame 8th facing side of the front panel 7a is fastened. On the screen carrier 16 Here are also here two in the direction of the frame 8th extending parallel webs 17 provided with a bolt 18 connected to each other, wherein the bolt 18 to the diaphragm carrier 16 spaced so that there is a free space between them. Here is the bolt 18 that of the locking device 14 behind element.

This embodiment of the connection fitting 15 is preferred, but is not mandatory, but may be varied as long as one of the locking device 14 behind tangible element on the panel 16 or the front panel 7a , b itself is provided.

The locking device 14 is on a support element 19 ( 4 or 11 ) of the frame 8 attached as an abutment. Here is the connection fitting 15 further with an adjusting device 50 from the position (Y and / or Z direction) relative to the locking device 14 adjustable, which is advantageous but not mandatory.

The carrier element 19 Here is a Zargenadapter, which is also designed here as a sheet metal part, and the frame 8th for example, in the cavity 13 can be fixed, for example on the inner shell 11 or the outer shell 12 , The carrier element 19 Can also be made in one piece with the frame 8th be designed. It serves as an abutment for the locking device 14 on the frame 8th ,

On the support element 19 is a basic body, here a base plate arrangement with here two base plates 20 . 21 , attached. The base plates 20 . 21 extend in sections parallel to each other and are spaced from each other. They are angled here at one or more edges. Here are the base plates 20 . 21 on both sides of the carrier element 19 and are at this with fasteners 22 and the side adjusting device 50 adjustable attached.

The base plates 20 . 21 stand in the direction of the front panel 7a or here the connection fitting 15 both sections on the support element 19 before, so that between you a slot 23 is trained ( 4 ). Instead of two (or more) base plates 20 . 21 For example, the base plate assembly could include only a single base plate or more base plates than two, the dual base plate version 20 . 21 However, it is preferred because the elements to be described are held and guided well and securely. The base plates 20 . 21 are with fasteners such as rivets or the like. (Reference numerals 22 ) with each other to a flat base plate assembly with the slot 23 connected. They are on the support element 19 according to a variant arranged adjustable or fixed by another variant fixed - that is not adjustable - positioned.

• - einen ein- oder mehrteiligen Auslösehebel 24,
• - einen Fanghebel 25, und
• - einen Kraftspeicher, hier in Form eines Federelementes 26.

Next to the or the base plates 20 . 21 as a body, the locking device 14 three on the base plate assembly relative to this at least limited movably arranged main functional elements on:

• - A single or multi-part release lever 24 .
• - a catch lever 25 , and
• - An energy storage, here in the form of a spring element 26 ,

The release lever 24 is arranged on the one outer side of the base plate assembly and the catch lever 25 on the other side or between the base plates 20 . 21 the plate assembly in the slot 23 , Here lies the catch lever 25 in the slot 23 , That's how these levers can work 24 . 25 each rotating and / or translational move on these pages. They are thus compact in a small space. In the side view - see eg 7a - are the release lever 24 and the catch lever 25 thus in sections one above the other.

The energy storage 26 is used for energy storage and release as well as for applying force to the release lever 24 and the catch lever 25 , It can be configured in various ways, with a preferred and advantageous embodiment being described below.

The energy storage 26 is after 4 to 10 each designed as a spiral spring arrangement, which is very advantageous, but again not mandatory.

This energy storage 26 as a spiral spring arrangement forms a particularly advantageous designed power storage for applying force to the locking devices in particular according to the accompanying figures, but also forms an independent invention and is thus advantageous as energy storage device for use on fittings of various kinds, in particular furniture fittings.

The spiral spring arrangement comprises a bending spring 28 (see also 5 ), here a wire bending spring, which has a U-shaped basic shape with two longitudinal legs 29 . 30 , having. These longitudinal legs may have a bend 31 be connected with each other (see 5 and 6 ). But it is also conceivable that the longitudinal legs 29 , 30 not with each other are connected, so that the bending spring 28 not in one piece but designed in several pieces (not shown here).

This is where the bend goes 31 and the longitudinal legs 29 . 30 largely in one plane. This plane runs parallel to the base plate arrangement here - here to the base plates 20 . 21 in the X / Z plane. The spiral spring 28 is thus housed very compact parallel to the base plate assembly. It lies substantially on the outside of the base plate assembly parallel to this.

The two longitudinal legs 29 . 30 the spiral spring 28 can be compressed in the Z direction at their free ends, causing the spiral spring 28 Energy stores by relaxing - ie by moving the longitudinal legs 29 . 30 away from each other - can be released again, in a manner to be described, the release lever 24 and the catch lever 25 to move. Here is the spiral spring 28 in sections, around a spring core 32 laid (see 6 ), which serves as a spring amplifier.

It is also conceivable that the two longitudinal legs 29 . 30 each with its one ends in (eg blind hole) openings of the spring core 32 plugged in and are held and fixed (not shown here).

The spring core 32 has one to the shape of the bent longitudinal leg 29 . 30 adapted shape and allows partial support of these longitudinal legs 29, 30 over part of the length of these legs, in particular in their sections, which widening to the bend 31 connect ( 6 ) or attached to the ends of the longitudinal legs 29 . 30 connect that to the spring core 32 are turned.

In addition, on the spring core 32 laterally two parallel walls 33 . 34 formed between which a slot 35 is formed, in which the longitudinal leg 29 . 30 over part of its length and, if present, preferably the bend 31 are arranged.

Such is the spiral spring 28 well protected and guided defined on the spring core 32 , Through the spring core 32 their effect is optimally optimized. The walls 33 . 34 lie parallel to the plate assembly in the X / Z plane. In the following figures, the function of the spiral spring is shown in interaction with a spring core. The task and the advantage achieved here of the spring core 32 it is, the spiral spring 28 to lead and in the spiral spring 28 storable or stored energy against a spring without core to increase. It is conceivable to design the spring core in one or more pieces.

The physical basis for the design of the spring core 32 lies in a preferred embodiment therein, the one or more parts bending spring 28 of the energy store 26 - bias partially or even in almost every area to the very or relatively close to the smallest possible elastic bending radius - which is understood here as an energy increase, since this position would not be practically usable without spring amplifier. If this radius is undershot, a plastic deformation occurs in the spiral spring 28 on, whereby a further energy storage is no longer possible. The spiral spring 28 is then overstretched. Conceptually corresponds to the spring core 32 a portion of a cylinder around which the spring wire is wound and when unwinding again assumes the straight shape. Parameters required for calculation are wire cross-section, material yield strength, modulus of elasticity. Thus, with a material yield strength of 1100 N / mm ² , a spring diameter of 2.5 mm, an E modulus of 185000 N / mm ² on a wire wound around a cylinder results in a bending inner radius of 208, 98 mm. Alternatively, the spring core 32 to be designed simply in an attempt.

The radius R of the spring core 32 (please refer 7a ) preferably corresponds to the greatest possible elastic elongation of the spiral spring without adverse deformation effects.

Preferably, the arcuate longitudinal legs 29 . 30 parallel to the main extension direction of the frame 8th arranged and the bend 31 the spiral spring 28 lies to that of the connection fitting 15 opposite side of the locking device 14 oriented so that the spiral spring 28 good in the X direction long cavity 13 the frame 8th on the release lever 24 opposite side of the locking device can be accommodated.

The longitudinal legs 29 . 30 are each at their free ends 36 . 37 , in assembly position on the frame 8th or on the pre-assembled drawer 4 in the direction of the front panel 7a oriented 90 ° (ie perpendicular to the base plate assembly) bent over. The one - here upper - free end 36 passes through a hole 38 the base plate assembly (here the two base plates 20 . 21 ) and the other - here lower free end 37 on the other hand, a slot (or a slot 39 ) of the base plate assembly (here the two base plates 20 . 21 ). The hole 38 and the slot 39 lie here in the Z direction (in the usual installation position on a drawer, the vertical direction) vertically aligned. The slot 39 is also vertically aligned here and lies here in the vertical direction (Z) below the hole 38 ,

This is the one free end - here the upper end - 36 of the spiral spring defined stationary but preferably rotatable on the base plate assembly in the bore 38 while the other - here lower free end 37 in the slot 39 the base plate assembly can move.

The lower free end 37 the spiral spring 28 further penetrates a hole 40 the release lever 24 , The lower free end 37 thus serves as a rotary shaft for the release lever 24 that is about the free end 37 the spiral spring 28 turn, which in turn is in the slot 39 can move. Such is the release lever 24 perform a superimposed rotational and translational movement of the base plate assembly.

The lower free end 37 the spiral spring 28 also penetrates a hole 41 of the catch lever 25 , so that this can perform a superimposed rotational and translational movement of the base plate assembly. In this case, the catch lever 25 also has a slot 42 on, which is here slightly bent executed and above the bore 41 lies. This slot 42 is from the other - here upper - free end 36 the spiral spring 28 interspersed. This is the catch lever 25 forced to a defined rotational and translational motion (to be described later) when the lower free end 37 the spiral spring 28 in the slot 39 the base plate assembly shifts what the catch lever 25 entraining.

Is the lower free end 37 the spiral spring 28 at the upper end of the slot 39 the base plate assembly is the spiral spring 28 curious; excited. This position corresponds to a position in which the front panel 7 not yet attached.

Is the lower free end 37 the spiral spring 28 however, at the bottom of the slot 39 the base plate order, is the bending spring 28 in her relaxed state. This position corresponds to a position in which the front panel 7 has been fastened. The catch lever 25 has a hook-like locking 43 on, then the undercut, here the bolt 18 of the connection fitting 15 , engages, which then into a horizontally extending slot 44 the base plate assembly is inserted in the direction of the front panel 7a is open.

So that the bending spring 28 can be held in the cocked position and so that it can be solved from this and thus the bending spring 28 from the relaxed position can be moved to the cocked, is the trigger 24 intended.

The release lever 24 has a torque transmission contour 45 on. Here, this is not intended for direct manual movement, but for applying a corresponding tool (exemplary training: Phillips and screwdriver).

The release lever 24 also has an arc shape, wherein at the inner radius of this arc a control contour 46 is trained. With this control contour 46 is adjacent to the release lever 25 in mounted position on the base plate assembly to a pin 47 ( 7b ), which is provided on the side of the base plate assembly and protrudes from this, on which also the release lever 24 is provided.

Here is the vote of control contour 46 and pen 47 and the pivot bearing at the lower free end 37 the spiral spring 28 in the slot 39 such that the release lever 24 with the tool in a release position is movable, in which the lower free end 37 the spiral spring 28 in the slot 39 the base plate assembly is located at the upper end, so that the bending spring 28 is curious. The control contour 46 has a cam section for this purpose 48 on. Upon rotation of the trigger lever 24 in the position in which the one free end 37 the spiral spring 28 in the slot 39 of the base plate assembly is at the top, the cam portion 48 have been run over in a locking direction / position. This position is in the manner of an over-center position a very stable position (here 6 . 7b ). It requires an external action, a trigger to the locking device or the release lever 24 to get out of this position.

The locking device 14 is biased in this state. The arresting 43 of the catch lever 25 is outside - here above - the slot 44 for inserting the connection fitting 15.

In this position is also a free end 49 - a footbridge 49 - Of the trigger lever 24 approximately at the height of the slot 44 for inserting the connection fitting 15. This free end 49 the release lever 24 is sized so that when attaching the front panel an edge of the connection fitting 15 comes to the plant ( 7a . 7b ). Upon further insertion of the connection fitting 15 or the front panel 7a or 7b becomes the free end 49 the release lever 24 Moved so that the release lever 24 starts to turn. In this rotation, the cam portion 48 run over in the opposite direction as when tightening ( 8a . 8b ). This solves the arrangement of the over-center position. As a result, now the spring, here the bending spring 28 , relax. This in turn causes the already described movement of the catch lever 25 in the locked position. The lower free end of the spiral spring 28 pull the catch lever 25 down, leaving the top end 36 the catch lever 25 in the Backdrop or in the slot 42 of the catch lever 25 is moved.

The vote of the slots or scenes and pivot bearing of the locking device 14 is such that the catch 25 the undercut (here the bolt 18 ) of the connection fitting 15 with his arrestor 43 begins to reach behind, what the connection fitting 15 due to the effect of the spiral spring 28 continue to the locking device 14 pulls and holds on to this stable. This position can be released by turning the release lever back 24 with a tool, including the cam section again 48 to be run over by tool operation.

Overall, such a very compact and yet secure Arretierbeschlag is created.

The 11 to 19 show the embodiment of the invention of a shutter-locking fitting.

This shutter lock fitting is similar to that of 4 to 10 designed. Therefore, some of the same reference numerals have been given and it can be fully referenced to the description of the construction and the function of the first embodiment.

Hereinafter, a base plate assembly is used and described as the base body. This arrangement is advantageous. Instead of the base plate arrangement but in turn also a different shaped body can be used.

But there are also differences to 1 to 10 , Also the variant of 11 to 19 locks an aperture, in particular a front panel, securely on the respective frame and has a compact design. But it is suitable for panels and frames with a higher height, so for the front panels 7b out 1 and correspondingly higher frames 8th , which are the ones to be discussed below 11 to 19 to disclose by way of example.

In drawers with high walls, especially high front panels and high frames, come to improve the Blendenfest seat two superimposed fasteners or locking devices 14a . 14b each frame for use, which form such a multiple locking device, here a double-locking device.

The following is the operation of a fastening of the panel with two superimposed on the panel connection fittings 15 and two correspondingly superimposed locking devices 14a , b discussed on the frame, which together form the multiple locking device.

Desired is the two locking devices 14a . 14b and / or to be able to release and / or retract safety gears together in one single unlocking operation in order to remove the diaphragm. When locking should also be ensured that the locking devices 14a . 14b only trigger when the appropriate connection fitting 15 has reached its catching position, ie for each of the two locking devices 14a . 14b , which form the multi-locking device, a separate triggering is necessary.

Preferably, furthermore, each of the two locking devices 14a . 14b , which form the multi-locking device, allow a certain tolerance compensation to a play-free concern of the panel, in particular the front panel 7b , on or in front of the frame 8th to ensure.

Corresponding to this task are first on the aperture 7b , which is indicated here only by a rod-shaped element, per frame 8th two of the connecting fittings 15a . 15b arranged vertically one above the other. This is also synonymous as a multiple, here double connection fitting referred to below. The connection fittings 15a . 15b are identical to those of the 1 to 10 constructed and not further functionally coupled with each other. Alternatively, a single connection fitting with two spaced-apart bolts can be used.

In addition, on the frame 8th two locking devices 14a . 14b arranged vertically one above the other, which are mechanically coupled together. Such an arrangement is also referred to below as a double locking device.

The in the 11 ff pictured double locking device is designed to attach the front panel 7b to the frame 8th in each case the two superimposed connection fittings 15 on the front panel 7b each simultaneously ( 16 ) or one after the other ( 18 and 19 ) first to reach behind, then to pull up to the frame and then to this firmly - but releasably - to keep locked ( 17 ).

This illustrate the 11 to 16 in combination with 17 an attachment of a diaphragm, wherein the aperture 7b held and mounted parallel to the frame, 18 an attachment of an aperture in oblique / slightly tilted position, the lower Edge of the aperture 7b with the lower connection fitting 15a at the start leads and 19 an attachment of a tilted aligned when fitting iris, wherein the upper edge of the panel 7b with the upper connection fitting 15b leads. 17 each illustrates the so far not distinguishable locked or locked position.

The multiple locking device 14a . 14b is in turn formed on a base body, which on a support element 19 ( 4 or 11 ) is attachable. Here, the double connection fitting 14 Furthermore, with an adjusting device (not shown here) from the position (Y and / or Z-direction) be adjustable relative to the multiple locking device, which is advantageous but not mandatory.

The carrier element 19 Here is again a Zargenadapter, which in turn is further formed here as a sheet metal part, and on the frame 8th for example in a cavity 13 can be fixed, for example on the inner shell 11 or the outer shell 12 , The carrier element 19 in turn, can also be integral with the frame 8th be designed. In addition, even the main body can be designed in one piece with the carrier element. The carrier element serves as an abutment for the double-locking device 14 on the frame 8th ,

On the support element 19 is again one or in this embodiment, two base plates 20 . 21 attached, which in turn form a base plate assembly with the support member, which serves as a base body here. The base plates 20 . 21 extend in sections parallel to each other and are spaced from each other. They are angled here at one or more edges. Here are the base plates 20 . 21 on both sides of the carrier element 19 and are at this with fasteners 22 attached.

The base plates 20 . 21 stand in the direction of the front panel 7a or here the connection fitting 15 both sections on the support element 19 before, so that between you a slot partially 23 is formed (see in particular 12 ). Instead of two (or more) base plates 20 . 21 Again, the base plate assembly could have only a single base plate or more base plates than two, with the still to be described movable elements of the two locking devices 14a and 14b well and safely held and managed.

The base plates 20 . 21 are with fasteners 22 such as rivets or the like. Together to form a flat base plate assembly with the slot 23 connected. They are on the support element 19 according to a variant arranged adjustable or fixed by another variant fixed - that is not adjustable - positioned.

• - jeweils einen ein- oder mehrteiligen Auslösehebel 24a, 24b (wobei der obere Auslösehebel 24b nachfolgend auch als Auslöseverhinderer bezeichnet wird),
• - jeweils einen Fanghebel 25a, 25b und
• - jeweils zumindest einen Kraftspeicher 26a, 26b.

Next to the or the base plates 20 . 21 have the lower and upper lower locking device 14a and 14b the multiple locking device in each case three again on the base plate assembly relative to this at least limited movably arranged main functional elements ( 11 . 12 . 13 ):

• - In each case a one- or multi-part release lever 24a . 24b (where the upper release lever 24b hereinafter also referred to as tripping inhibitor),
• - one catch lever each 25a . 25b and
• - Each at least one energy storage 26a . 26b ,

The lower release lever 24a Here is an example of the energy storage 26a facing away from the outside of the body, here the base plate assembly, arranged ( 16b ).

The upper release lever or tripping prevention 24b is here in a preferred - but not mandatory - design in the slot 23 ,

Preferably, here are the lower and the upper catch lever 25a , b each compact and secure between the base plates 20 . 21 the base plate assembly in the slot 23 arranged where they are with the tripping prevention 24b interact.

In a side view - see eg 14 - are the lower release lever 24a and the catch lever 25a partially covered.

Here are the lower release lever 24a and the upper tripping prevention 24b with a rod-like coupling element, here a coupling lever 60 , mechanically functionally coupled with each other. This coupling lever 60 is here in a side view (see 16b ) designed in approximately C-shaped. It is here arranged on the outside of the base plate assembly, on which also the lower release lever 24a is arranged. The coupling lever 60 is hinged at its lower end with a bolt or pin 61 that the coupling lever 60 and the lower release lever 24a interspersed, connected.

The tripping prevention 24b is articulated at its upper end in yet to be described way with another bolt 62 arranged on the base body.

The coupling lever 60 is at its top - from the bottom release lever 24a facing away - end of a spring end 37 of the upper energy storage 26b interspersed. The coupling lever 60 and the lower release lever 24a may adopt a common over-center position in which the multiple Locking device is kept open in a manner to be described.

On the upper tripping prevention 24b acts another force storage device, which in addition to the two force accumulators 26a . 26b is provided. This further power storage device is here a spring 63 , This spring 63 is in a further preferred embodiment compact and simply formed as a leg spring. The one free arm 66 the spring is supported on the base body, here the base plate arrangement, for example in a hole or slot 65 Widerlager-like and the other arm 64 acts on the upper tripping prevention 24b and acts on this in the direction of the upper catch lever 25b with power.

The two energy storage 26a . 26b the two locking devices 14a and 14b serve in turn for energy storage and release and in particular for applying force to the lower release lever 24a and the two catch levers 25a , b. They are each, for example, by type 1 to 10 designed as a spiral spring arrangement, with the top and bottom of the type of articulation on the base plate assembly and the levers 24a such as 25a , b is different from each other. In this case, the bending springs 28a , b arranged in mirror image. The bending springs 28a , b may in turn be designed one or more pieces.

The two energy storage 26a , b with the single or multi-part bending springs 28a , b act in such a way with the catch levers 25a , b together, that they have this - unless they get it by the trigger 24a and the coupling lever 60 and / or the tripping prevention 24b be prevented, move to a position and hold in this, in which they the connecting fittings 15a . 15b with the front panel 7b to the two locking devices 14a , b of the multi-locking device.

These are the longitudinal legs 29 . 30 the two spring elements 26a , b again at their free ends 36 . 37 , in assembly position on the frame 8th or on the pre-assembled drawer 5 in the direction of the front panel 7a oriented 90 ° (ie perpendicular to the base plate assembly) bent over.

At the lower locking device 14a intersperses the one - here upper - end 36 the lower spiral spring 28a of the lower energy storage 26a the hole 38a the base plate assembly (here the two base plates 20 . 21 ) and the other - here lower - end 37 on the other hand, a slot (or a slot 39a ) of the base plate assembly (here the two base plates 20 . 21 ). The hole 38a and the slot 39a are here in the Z direction (in the usual installed position on a drawer, the vertical direction) vertically aligned. The slot 39a is also vertically aligned here and lies here in the vertical direction (Z) below the hole 38a ,

At the upper locking device 14b intersperses the one - here upper - end 36 the upper spiral spring 28b of the upper energy storage a slot 39b and the other - here bottom - end 37 on the other hand a hole 38b the base plate assembly (here the two base plates 20 . 21 ). The hole 38b and the slot 39b lie here in the Z direction (in the usual installation position on a drawer, the vertical direction) vertically aligned. Here even both slots are aligned 39a , b and both holes 38a , b.

The lower end 37 the lower spiral spring 28a of the lower spring element 26a further penetrates a hole 40a the lower release lever 24a located near the (in the Z direction) upper end of the lower release lever 24a lies.

The lower end 37 the lower spiral spring 28a of the lower energy storage 26a thus serves as a rotation axis / shaft for the lower release lever 24a that is about the free end 37 the spiral spring 28a can turn, which in turn can move in the slot 39a. Such is the release lever 24a perform a superimposed rotational and translational movement of the base body, here the base plate assembly.

The free bottom end 37 the lower spiral spring 28a also penetrates one in the lower part of the lower catch lever 25a lying hole 41a , Wherein this catch lever can perform a superimposed rotational and translational movement of the base plate assembly. In this case, the lower catch lever 25 also a slot 42a on, above the hole 41a lies. This slot 42a is from the other - here upper - free end 36 the lower spiral spring 28a interspersed. Such is the lower catch 25a (similar to 1 - 10 ) are forced to a defined rotational and translational motion (to be described later) when the lower free end 37 the lower spiral spring 28a in the slot 39a the base plate assembly shifts what the lower catch lever 25a moved.

The upper end 36 the upper spiral spring 28b does not penetrate the tripping device 24b , The free upper end 36 the upper spiral spring 28b but passes through a hole 41b of the upper catch lever 25b , Also, this can perform such a superimposed rotational and translational movement of the base plate assembly. In this case, the upper catch lever 25b in turn, a slot 42b on, below the hole 41b lies.

This slot 42b is from the other - here lower - free end 37 the upper spiral spring 28b interspersed. Such is the upper catch 25b also forced to a (to be described later) defined rotational and translational movement when the lower end 37 the upper spiral spring 28b in the slot 39b the base plate assembly can move or shift what the upper catch lever 25b entraining.

Is the free lower end 37 the lower spiral spring 28a at the upper end of the slot 39a the base plate assembly, this is bending spring 28a curious; excited. This position corresponds to a position in which the front panel 7b not yet attached (see eg 14 ). Is also the free upper end 36 the upper spiral spring 28b at the lower end of the slot 39a the base plate assembly, this is bending spring 28b curious; excited. This position again corresponds to a position in which the front panel 7b not attached ( 11 to 16 ).

Is the other end of the respective spiral spring 28a or 28b however, at the other end of the slot 39a or 39b of the main body, here the base plate order, is the respective bending spring 28a and or 28b in a more relaxed state. This position corresponds to a position in which the front panel 7b has been fastened ( 17 ).

Each of the two catch levers 25a . 25b has a hook-like locking 43a, b, which is designed, then the undercut, here the bolt 18a or 18b, which is then respectively inserted in a horizontally extending slot 44a, b of the base plate assembly, which faces the front panel 7b is open.

So that the bending springs 28a , b can be held in the cocked position and so that they can be released from this and thus the bending spring 28a , B can be moved from the relaxed position into the tensioned and back, the coupled, here articulated coupled elements lower release lever 24a and upper tripping prevention 24b intended.

The upper tripping prevention 24b is pivotable with the pin / bolt 62 on the body, here the base plate assembly stored. The power storage device assigned to him, here the spring 63 , pushes it towards the front panel 7b , The lower end works 67 the upper one by the spring 64 spring-loaded release lever 24b (see eg 14 ) on the upper catch 25b one.

This lower end 67 is designed so that the upper catch 25b so lockable is that the top slot 44b is free. Now is an upper connection fitting 15b to the frame 8th moves, the upper tripping preventer 24b against the force of the spring 63 from the aperture 7b pivoted away. As a result, the upper tripping preventer 24b is released so that the upper energy storage 26b on the upper catch 25b can act and move this, so that the upper connection fitting 15a to the frame 8th is used ( 16a . 19 ) and locked.

Also the lower release lever 24a is (as described) pivotally mounted on the base body, in particular the base plate assembly. However, the tripping prevention device 24b does not act on the lower arresting or catching device here 14a , The lower safety gear can always trigger. The tripping prevention 24 ensures that the upper locking device only triggers when a bolt is in position at the top. Only the unlocking is coupled.

The lower release lever acts 24a on the lower catch 25a one, so that also the lower slot 44a is free.

Will now be a lower connection fitting 15a on the front panel 7b in the lower slot 44b inserted ( 15 to 16 or 18 , the lower release lever 24a of the lower connection fitting 15a moved and also pivoted. This will cause the lower release lever 24a pivoted out of the over-center position, leaving the lower spring assembly 26b is released, so that the lower connection fitting 15a to the frame 8th is used.

The lower release lever 24a and the upper trip lever or preventer 24b can be actuated or triggered at the same time, in particular when the front panel 7b aligned parallel to the front edge of the frame ( 16a, b ).

Alternatively, the lower release lever 24a and the upper release lever or preventer 24b are, however, also actuated or triggered in succession, in particular if the front panel 7b is aligned obliquely at an angle to the front Zargenkante or Z-direction ( 18 . 19 ). It can either first the lower connection fitting 15a in the lower locking device 15a be introduced ( 18 ) or the upper connection fitting 15b in the upper locking device 15b ( 19 ).

The arrangement is such that when the lower connection fitting 15a first in the lower slot 44a is introduced and then the upper connection fitting 15b in the upper slot 44b , the lower locking device 14a timed first and then the upper locking device 14b ( 18 ).

The upper tripping prevention 24b holds due to the construction of stored energy (from the spring 63 ) directly the upper catch lever 25b in a stable locked position.

Will the lower connection fitting 15a or its bolt 18 in the lower slot 44 introduced, which reaches the lower locking device 14a facing edge of this connection fitting 15a the lower release lever 24a , so that it is pivoted from the over-center position backwards. Such is the lower locking device 14a trigger, leaving the bottom catch 25a the lower connection fitting 15a locked. By turning the lower release lever 24a is also the coupling lever 60 pivoted (see 18 ). Will then or at the same time the upper connection fitting 15b introduced, pushes his bolt 18b in the slot 44b on the tripping prevention 24b and pans it.

This will also the upper locking device 14b moved into its locking position, which is also the upper connection fitting 15b on the upper locking device 14b locked.

If, however, the upper connection fitting 15b first inserted and then the lower connection fitting 15a , releases the upper locking device 14b only off, although the lower locking device 14a ( 18 ) has triggered. The latter is only due to insertion of the lower connection fitting 15a Approved. Although the trigger is 24b above also already when inserting the upper connection fitting 15b pivoted. In this position, but still holds the lower release lever 24a over the vertically aligned coupling lever 60 the upper catch 25b in the open position. Only by the insertion of the lower connection fitting 15a and the pivoting of the lower release lever 24a also becomes the coupling lever 60 released from the stable vertical position, so that a corresponding locking of the upper connection fitting 15b on the upper locking device 14b he follows.

The lower release lever 24a in turn has a torque transmission contour 45. Again, this is not intended for a direct manual movement, but for applying a corresponding tool (exemplary training: Phillips and screwdriver). With the lower release lever 24a becomes the lower locking device 14a solved and then or at the same time via the coupling lever 60 also the upper tripping prevention 24b and thus the upper of the locking devices 14b ,

Overall, such a very compact, yet safe working locking fitting for high aperture is created.
