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 preamble of claim 1 is the DE 20 2009 014811 U1 called.

The DE 10 2010 060 722 A1 discloses a locking fitting, which comprises a locking device having an energy storage device, which is arranged on the frame and a corresponding connection fitting on a furniture panel, in particular on a front panel, which can be pulled up to the front panel with a catch lever on which the energy storage unit acts. A manually operated release lever is provided.

For drawers with high sides, two superimposed fastenings per frame are used to improve the fixed panel fit. It is known, for example, to fix the cover to the frame with two connection fittings lying one above the other on the cover and two correspondingly arranged 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 release the two locking devices or catch devices together in only one unlocking operation in order to remove the panel from the frame. When locking, it should also be ensured that the locking devices only release when the corresponding connecting fitting has reached the catch position, i.e. separate triggering is required for each safety gear.

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

The invention solves this problem by the subject matter of claims 1, 13 and 14.

With the multiple locking device obtained in this way, the functionality and nature required in the task can be implemented excellently, which in particular will also clarify the description of preferred exemplary embodiments. The two locking devices each have a first energy storage device and the second locking device additionally has a (further) energy storage device, which acts on the release preventer, which serves to prevent the second energy storage device from being triggered in the open position.

In order to implement the required functionality, it is advantageous if the release lever and the coupling lever can be brought into and out of a common over-center position.

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

The base body can consist of one or more elements, which can be mutually adjustable, if necessary, and can be at least sectionally plate-shaped. The elements of the base body can advantageously be designed as a base plate arrangement with at least one base plate. The term "base plate" should not be interpreted too narrowly. In any case, this includes sections which are just designed in sections, but also one or more struts, etc. In an embodiment with two or more base plates, a slot may be present between them. If necessary, this can advantageously be used for the safe arrangement of one or more functional elements.

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

With regard to a compact structure, it is further advantageous if the lower release lever is arranged on one outer side of the base body and the lower one Catch lever on the other outside or between two elements of the base body in a slot. In this way, these levers can move well without hindering each other's movement. Preferably, the release lever is also rotatably mounted on one end of the energy accumulator, which is also slidably guided in the elongated hole of the base body.

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

It can advantageously be provided that the spiral spring arrangement has a V-shaped or U-shaped spiral spring with two arcuate longitudinal legs, which are formed in one piece or in each case individually, the longitudinal legs being connected to one another via a bend in a one-piece configuration.

Then it is further advantageous in terms of the compact structure and the good function if the two arcuate longitudinal legs each have a bent end, which form the free ends of the spring arrangement, which elements to be loaded with force, in particular the base body, the release lever and the Catch lever, intervene and preferably fully or partially push it through.

So that the spiral spring does not have to be designed too large, it is further advantageous if the spiral spring arrangement has a spring amplifier. The function of the spring core is to guide the spiral spring and to allow a very good prestressing, preferably an almost maximum prestressing of the spiral spring.

In terms of design, this can be easily achieved by the spiral spring or its longitudinal leg being / are in some cases placed around a spring core which serves as a spring amplifier.

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

According to a further variant, it can advantageously be provided that the release lever of the first locking device has a torque transmission contour for attaching a corresponding tool.

Also created are a frame for a drawer with a locking device according to one of the claims related thereto and a drawer with a frame according to claim 13 and with a panel with a connecting fitting which is attached to the locking device.

Further advantageous embodiments of the invention can be found in the subclaims.

In Fig. 1 furniture 1 with a furniture body 2 with side walls 3 is shown. In the furniture body 2, several here - purely by way of example three - drawers 4, 5, 6 are placed between the side walls 3, which are displaceably guided on the inside of the side walls 3 by means of pull-out guides (not shown here), so that each of the drawers 4 , 5, 6 each can be pulled out of the furniture body 2 into an open position and again pushed out of this into a closed position.

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

The frame 8 has (see Fig. 2 ) a main direction X. This direction X is also the direction in which the drawer can be inserted into and withdrawn from the furniture body 3. The after Fig. 1 vertical direction is the direction Y - in which the width of the frame 8 is measured - and the other vertical direction in the usual installation position is the direction Z.

The frames 8 - see Fig. 2 and 3rd - Are preferably constructed in two shells and have an inner shell 11 and an outer shell 12. The inner shell 11 and the outer shell 12 each have a narrow cavity 13. A single-shell structure with a corresponding cavity would also be conceivable.

The outer shell 12 and the inner shell 11 preferably - but not necessarily - consist of a metal, in particular steel sheets, or of a light metal, in particular of aluminum or an aluminum alloy.

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

The front panels 7a, b are each mounted and held on the two frames 8 with at least one panel locking fitting, consisting of a connecting fitting 15 attached to the front panel and a locking device 14 arranged and attached to the frame 8 ( 4 to 10 ).

In the Fig. 2 frame 8 shown therefore has in each case the in Fig. 4 ff or those in the Fig. 11 ff illustrated locking device 14, which is designed to engage the connecting bracket 15 on the front panel 7a when the front panel 7a or b is attached to the frame 8, then pull it up to the frame 8 and then firmly on it - but releasable - to keep locked. This is in the 6 to 10 shown in several successive steps.

Since the frame 8 is designed to be relatively narrow in the Y direction and, at least in the case of variants, also vertically relatively flat, it is necessary to provide a correspondingly compact, yet safe and well-functioning locking device 14.

This is implemented with the locking device 14 to be described below, which is designed to engage behind the connecting fitting 15 and to secure it to the frame 8.

First, the connection fitting 15 is briefly considered. The connection fitting 15 has a panel support 16 - see Fig. 5 and 6 - On, which can be fastened with one or more fastening means (not shown here) like screws on the side of the front panel 7a facing the frame 8. In this case, two parallel webs 17, which extend in the direction of the frame 8 and are connected to one another by a bolt 18, are provided on the panel carrier 16, the bolt 18 being spaced apart from the panel carrier 16 so that a space is formed between them. Here, the bolt 18 is the element to be gripped behind by the locking device 14.

This configuration of the connection fitting 15 is preferred, but is not mandatory, but can be varied as long as an element that can be gripped behind by the locking device 14 is provided on the panel support 16 or the front panel 7a, b itself.

The locking device 14 is on a carrier element 19 ( Fig. 4 or 11 ) the frame 8 attached as an abutment. The connecting fitting 15 can also be adjusted with an adjusting device 50 from the position (Y and / or Z direction) relative to the locking device 14, which is advantageous but not mandatory.

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

A base body, here a base plate arrangement with here two base plates 20, 21, is attached to the carrier element 19. The base plates 20, 21 extend in sections parallel to one another and are spaced apart. They are angled at one or more edges here. Here, the base plates 20, 21 are located on both sides of the carrier element 19 and are adjustably fastened to it with fastening means 22 and the side adjusting device 50.

The base plates 20, 21 protrude in sections in the direction of the front panel 7a or here the connecting fitting 15 in sections over the carrier element 19, so that a slot 23 is formed between them ( Fig. 4 ). Instead of two (or more more) base plates 20, 21, the base plate arrangement could also have only a single base plate or more base plates than two, but the embodiment with two base plates 20, 21 is preferred because the elements to be described are held and guided well and securely on them. The base plates 20, 21 are connected to one another by means of fastening means such as rivets or the like (reference number 22) to form a flat base plate arrangement with the slot 23. In this case, they are arranged on the carrier element 19 so as to be adjustable according to one variant, or according to another variant they are fixedly positioned, ie not adjustable.

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

In addition to the base plate or plates 20, 21 as the base body, the locking device 14 has three main functional elements, which are arranged to be movable in any case relative to the base plate arrangement:

• a one- or multi-part release lever 24,
• a catch lever 25, and
• an energy accumulator, here in the form of a spring element 26.

The release lever 24 is arranged on one outside of the base plate arrangement and the catch lever 25 on the other side or between the base plates 20, 21 of the plate arrangement in the slot 23. Here, the catch lever 25 lies in the slot 23 , 25 each rotate and / or translate on these pages. They are compact in a confined space. In the side view - see e.g. Fig. 7a - The trigger lever 24 and the catch lever 25 are thus in sections one above the other.

The energy store 26 serves for energy storage and release as well as for the application of force to the release lever 24 and the catch lever 25. It can be designed per se in various ways, a preferred and advantageous embodiment being described below.

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

This energy store 26 as a spiral spring arrangement forms a particularly advantageously designed energy store for applying force to the locking devices, in particular according to the attached figures, but also forms an independent invention and is therefore suitable as an energy store for use on various types of fittings, in particular on furniture fittings.

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

The bend 31 and the longitudinal legs 29, 30 run 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 accommodated in a very compact manner parallel to the base plate arrangement. Here it lies essentially on the outside of the base plate arrangement parallel to the latter.

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

It is also conceivable that the two longitudinal legs 29, 30 each have their one ends inserted into (for example blind-hole-like) openings in the spring core 32 and are held and fixed in this way (not shown here).

The spring core 32 has a shape adapted to the shape of the curved longitudinal legs 29, 30 and enables a partial support of these longitudinal legs 29, 30 over part of the length of these legs, in particular in their sections which widen following the bend 31 ( Fig. 6 ) or which connect to the ends of the longitudinal legs 29, 30 which face the spring core 32.

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

In this way, the spiral spring 28 is well protected and guided in a defined manner on the spring core 32. The spring core 32 advantageously optimizes its effect. The walls 33, 34 lie parallel to the plate arrangement in the X / Z plane. The function of the spiral spring in interaction with a spring core is shown in the following figures. The task and the advantage of the spring core 32 achieved here are to guide the spiral spring 28 and to increase the energy which can be stored or stored in the spiral spring 28 compared to a spring without a core. It is conceivable to design the spring core in one or more pieces.

According to a preferred embodiment, the physical basis for the design of the spring core 32 lies in prestressing the one-part or multi-part spiral spring 28 of the energy accumulator 26 - in part or even in almost any area to completely or relatively close to the smallest possible elastic bending radius, which here as Energy increase is understood, since this position would not be practically usable without a spring amplifier. If this radius is undershot, plastic deformation occurs in the spiral spring 28, as a result of which further energy storage is no longer possible. The spiral spring 28 is then overstretched. According to the concept, the spring core 32 corresponds to a section of a cylinder, around which the spring wire is wound and, when it is unwound, assumes the straight shape again. The parameters required for the calculation are wire cross-section, material yield strength, modulus of elasticity. This results in a material yield strength of 1100 N / mm ^2, a spring diameter of 2.5 mm, a modulus of elasticity of 185,000 N / mm ² at a coil wound around a cylindrical wire, a bending inner radius of 208, 98 mm. Alternatively, the spring core 32 can be simply suitably designed in the experiment.

The radius R of the spring core 32 (see Fig. 7a ) preferably corresponds to the greatest possible elastic expansion of the spiral spring without disadvantageous deformation effects.

The arcuate longitudinal legs 29, 30 are preferably arranged parallel to the main direction of extension of the frame 8 and the bend 31 of the spiral spring 28 is oriented towards the side of the locking device 14 facing away from the connecting fitting 15, so that the spiral spring 28 extends well in the direction of the X direction Cavity 13 of the frame 8 can be accommodated on the side of the locking device facing away from the release lever 24.

The longitudinal legs 29, 30 are each bent by 90 ° (i.e. perpendicular to the base plate arrangement) at their free ends 36, 37, which are oriented in the assembly position on the frame 8 or on the preassembled drawer 4 in the direction of the front panel 7a. One - here upper - free end 36 passes through a bore 38 of the base plate arrangement (here the two base plates 20, 21) and the other - here lower free end 37 on the other hand an elongated hole (or a slot 39) of the base plate arrangement (here the two base plates 20, 21). The bore 38 and the elongated hole 39 are here in the Z direction (in the usual installation position on a drawer the vertical direction) in vertical alignment. The elongated hole 39 is also oriented vertically here and lies here in the vertical direction (Z) below the bore 38.

Thus, one free end - here the upper end - 36 of the spiral spring defines fixed but preferably rotatable on the base plate arrangement in the bore 38, while the other - here lower free end 37 can move in the slot 39 of the base plate arrangement.

The lower free end 37 of the spiral spring 28 also passes through a bore 40 of the trigger lever 24. The lower free end 37 thus serves as a rotary shaft for the trigger lever 24, which can rotate about the free end 37 of the spiral spring 28, which in turn rotates in the slot 39 can move. In this way, the trigger lever 24 can perform a superimposed rotary and translational movement on the base plate arrangement.

The lower free end 37 of the spiral spring 28 also passes through a bore 41 of the catch lever 25, so that this can also perform a superimposed rotational and translational movement on the base plate arrangement. The catch lever 25 also has an elongated hole 42, which is here slightly curved and lies above the bore 41. This slot 42 is penetrated by the other - here upper - free end 36 of the spiral spring 28. In this way, the catch lever 25 is forced to perform a defined rotational and translational movement (to be described in more detail) when the lower free end 37 of the spiral spring 28 moves in the elongated hole 39 of the base plate arrangement, which takes the catch lever 25 with it.

If the lower free end 37 of the spiral spring 28 is located at the upper end of the elongated hole 39 of the base plate arrangement, the spiral spring 28 is tensioned. This position corresponds to a position in which the front panel 7 is not yet attached.

If, on the other hand, the lower free end 37 of the spiral spring 28 is located at the lower end of the elongated hole 39 of the base plate arrangement, the spiral spring 28 is in its relaxed state. This position corresponds to a position in which the front panel 7 has been attached. The catch lever 25 has a hook-like locking end 43 which then engages behind the undercut, here the bolt 18 of the connecting fitting 15, which is then inserted into a horizontally extending slot 44 in the base plate arrangement, which is open in the direction of the front panel 7a.

The release lever 24 is provided so that the spiral spring 28 can be held in the tensioned position and so that it can be released from it and also that the spiral spring 28 can be moved from the relaxed position into the tensioned position.

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

The trigger lever 24 also has an arc shape, a control contour 46 being formed on the inner radius of this arc. With this control contour 46, the release lever 25 borders in the assembled position on the base plate arrangement on a pin 47 ( Fig. 7b ), which is provided on the side of the base plate arrangement and projects from it, on which the release lever 24 is also provided.

The control contour 46 and pin 47 and the rotary bearing are coordinated at the lower free end 37 of the spiral spring 28 in the elongated hole 39 in such a way that the release lever 24 can be moved with the tool into a release position in which the lower free end 37 of the spiral spring 28 lies in the elongated hole 39 of the base plate arrangement at the upper end, so that the spiral spring 28 is tensioned. For this purpose, the control contour 46 has a cam section 48. When the trigger lever 24 is turned into the position in which the one free end 37 of the spiral spring 28 in the elongated hole 39 of the base plate arrangement is at the top, the cam section 48 has been run over in a locking direction / position. In the manner of an over-center position, this position is a very stable position (here Fig. 6 , 7b ). An external action, a release, is required in order to release the locking device or the release lever 24 from this position.

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

In this position there is also a free end 49 - a web 49 - of the release lever 24 approximately at the height of the slot 44 for inserting the connecting fitting 15. This free end 49 of the release lever 24 is dimensioned such that an edge is attached to it when the front panel is attached of connection fitting 15 comes into contact ( Fig. 7a , 7b ). When the connecting fitting 15 or the front panel 7a or 7b is pushed in further, the free end 49 of the release lever 24 is moved further, so that the release lever 24 begins to rotate. During this rotation, the cam section 48 is passed over in the opposite direction to that during tensioning ( Fig. 8a , 8b ). This releases the arrangement from the over-dead center position. As a result, the spring, here the spiral spring 28, can now relax. This in turn causes the catch lever 25 to be moved into the locking position. The lower free end of the spiral spring 28 pulls the catch lever 25 downward, so that the upper end 36 of the catch lever 25 is displaced in the link or in the slot 42 of the catch lever 25.

The coordination of the elongated holes or links and pivot bearing of the locking device 14 is such that the catch lever 25 begins to engage behind the undercut (here the pin 18) of the connecting fitting 15 with its locking end 43, which results in the connecting fitting 15 due to the action of the spiral spring 28 further pulls on the locking device 14 and holds it stably. This position can be released by turning the trigger lever 24 back with a tool, for which purpose the cam section 48 can be moved over again by operating the tool.

Overall, this creates a very compact and yet secure locking fitting.

The 11 to 19 show the inventive embodiment of a panel locking fitting.

This panel locking fitting is similar to that of the 4 to 10 designed. For this reason, the same reference numerals have been assigned in some cases, and reference can be made in full to the description of the structure and function of the first exemplary embodiment.

A base plate arrangement is used and described below as the base body. This arrangement is advantageous. Instead of the base plate arrangement, however, a differently shaped base body can also be used.

But there are also differences to 1 to 10 . Even the variant of 11 to 19 locks a panel, especially a front panel, securely on the respective frame and has a compact design. But it is suitable for panels and frames with a greater height, so for the front panels 7b Fig. 1 and correspondingly higher frames 8, which are those to be discussed below Figures 11 to 19 disclose by way of example.

In drawers with high walls, in particular high front panels and high frames, two superimposed fastenings or locking devices 14a, 14b per frame are used to improve the fixed fit of the panel, which form such a multiple locking device, here a double locking device.

The mode of operation of fastening the panel with two connecting fittings 15 lying one above the other on the panel and two correspondingly arranged locking devices 14a, b on the frame, which together form the multiple locking device, is discussed below.

It is desirable to be able to release (and pretension) the two locking devices 14a, 14b or catch devices together in only one unlocking operation in order to remove the panel. When locking, it should also be ensured that the locking devices 14a, 14b only release when the corresponding connecting fitting 15 has reached its catch position, ie a separate release is necessary for each of the two locking devices 14a, 14b, which form the multiple locking device .

Preferably, each of the two locking devices 14a, 14b, which form the multiple locking device, should allow a certain tolerance compensation in order to ensure that the panel, in particular the front panel 7b, bears against the frame 8 without play.

Corresponding to this task, two of the connecting fittings 15a, 15b are first arranged vertically one above the other on the diaphragm 7b, which is indicated here only by a rod-shaped element. In the following, this is also referred to synonymously as multiple, here double connection fitting. The connecting fittings 15a, 15b are each identical in construction to those of the Fig. 1 to 10 built up and no longer functionally linked. Alternatively, a single connection fitting with two bolts arranged one above the other at a distance can also be used.

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

The in the Fig. 11 ff shown double locking device is designed to, when attaching the front panel 7b to the frame 8, the two superimposed connecting fittings 15 on the front panel 7b each simultaneously ( Fig. 16 ) or one after the other ( Fig. 18 and19) reach behind, then pull up to the frame and then hold it firmly - but releasably - locked ( Fig. 17 ).

The illustrate 11 to 16 in combination with Fig. 17 an attachment of a panel, in which the panel 7b is held and mounted parallel to the frame, Fig. 18 an attachment of a panel in an inclined / slightly tilted position, the lower edge of the panel 7b with the lower connecting fitting 15a leading in the attachment and Fig. 19 an attachment of an aperture which is tilted during the attachment, the upper edge of the aperture 7b leading the upper connecting fitting 15b. Fig. 17 illustrates the locked or locked position that cannot be distinguished in this respect.

The multiple locking device 14a, 14b is in turn formed on a base body which is attached to a carrier element 19 ( Fig. 4 or 11 ) can be attached. It can the double connection fitting 14 can also be adjusted with an adjusting device (not shown here) from the position (Y and / or Z direction) relative to the multiple locking device, which is advantageous but not mandatory.

The carrier element 19 is here again a frame adapter, which here is also again in the form of a sheet metal part and which can be fixed to the frame 8, for example in a cavity 13, e.g. on the inner shell 11 or the outer shell 12. The carrier element 19 can in turn also be designed in one piece with the frame 8. In addition, even the base 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 8.

On the carrier element 19, in turn, one or, in this exemplary embodiment, two base plates 20, 21 are fastened, which in turn form a base plate arrangement with the carrier element, which serves as the base body here. The base plates 20, 21 extend in sections parallel to one another and are spaced apart. They are angled at one or more edges here. Here, the base plates 20, 21 are located on both sides of the carrier element 19 and are fastened to it with fastening means 22.

The base plates 20, 21 protrude in sections in the direction of the front panel 7a or here the connecting fitting 15, in sections, over the carrier element 19, so that a slot 23 is formed in some areas between them (see in particular Fig. 12 ). Instead of two (or even more) base plates 20, 21, the base plate arrangement could also have only a single base plate or more base plates than two, the movable elements of the two locking devices 14a and 14b to be described being held and guided well and securely.

The base plates 20, 21 are connected to one another by means of fastening means 22 such as rivets or the like to form a flat base plate arrangement with the slot 23. In this case, they are arranged on the carrier element 19 so as to be adjustable according to one variant, or according to another variant they are fixedly positioned, ie not adjustable.

• 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.

In addition to the base plate or plates 20, 21, the lower and the upper lower locking device 14a and 14b of the multiple locking device each have three of the base plate arrangement relative to the main functional elements, which are in any case limitedly movable. Fig. 11 , 12th , 13 ):

• in each case a one-part or multi-part trigger lever 24a, 24b (the upper trigger lever 24b also being referred to below as a trigger preventer),
• a catch lever 25a, 25b and
• in each case at least one energy accumulator 26a, 26b.

The lower release lever 24a is arranged here, for example, on the outside of the base body, here the base plate arrangement, facing away from the energy accumulator 26a ( Fig. 16b ).

The upper trigger lever or trigger preventer 24b lies here in the preferred — but not mandatory — configuration in the slot 23.

Preferably, the lower and the upper catch levers 25a, b are each arranged compactly and securely between the base plates 20, 21 of the base plate arrangement in the slot 23, where they cooperate with the release preventer 24b.

In a side view - see e.g. Fig. 14 - The lower trigger lever 24a and the catch lever 25a are partially in register.

The lower trigger lever 24a and the upper trigger preventer 24b are mechanically functionally coupled to one another with a rod-like coupling element, here a coupling lever 60. This coupling lever 60 is here in a side view (see Fig. 16b ) designed approximately C-shaped. It is arranged here on the outside of the base plate arrangement, on which the lower release lever 24a is also arranged. The coupling lever 60 is articulated at its lower end with a bolt or pin 61 which passes through the coupling lever 60 and the lower trigger lever 24a.

The trigger preventer 24b is articulated at its upper end in a manner to be described with a further bolt 62 on the base body.

The coupling lever 60 is penetrated at its upper end, facing away from the lower trigger lever 24a, by a spring end 37 of the upper energy accumulator 26b.

The coupling lever 60 and the lower release lever 24a can assume a common dead center position in which the multiple locking device is kept open in a manner to be described.

A further force storage device acts on the upper release preventer 24b, which is provided in addition to the two force stores 26a, 26b. This further energy storage device is here a spring 63. In a further preferred embodiment, this spring 63 is compact and simple as a leg spring. One free arm 66 of the spring is supported on the base body, here the base plate arrangement, in an abutment-like manner, for example in a hole or slot 65, and the other arm 64 acts on the upper release preventer 24b and applies force to it in the direction of the upper catch lever 25b.

The two energy stores 26a, 26b of the two locking devices 14a and 14b in turn serve for energy storage and release, and in particular for the application of force to the lower release lever 24a and the two catch levers 25a, b. They are, for example, according to the type of 1 to 10 designed as a spiral spring arrangement, the type of articulation on the base plate arrangement and on the levers 24a and 25a, 25b differing from one another above and below. In this case, the bending springs 28a, b are arranged in mirror image. The bending springs 28a, b can in turn each be designed in one or more pieces.

The two energy accumulators 26a, b with the one-part or multi-part bending springs 28a, b cooperate with the catch levers 25a, b in such a way that they - unless they are prevented from doing so by the release lever 24a and the coupling lever 60 and / or the release preventer 24b , move into a position and hold it in which they pull the connecting fittings 15a, 15b with the front panel 7b onto the two locking devices 14a, b of the multiple locking device.

For this purpose, the longitudinal legs 29, 30 of the two spring elements 26a, b are in turn each at their free ends 36, 37, which are oriented in the mounting position on the frame 8 or on the preassembled drawer 5 in the direction of the front panel 7a, by 90 ° (ie vertically bent over to the base plate arrangement).

On the lower locking device 14a, the one - here upper - end 36 of the lower spiral spring 28a of the lower energy accumulator 26a penetrates the bore 38a of the base plate arrangement (here the two base plates 20, 21) and the other - here lower - end 37 on the other hand an elongated hole (or a slot 39a) of the base plate arrangement (here the two base plates 20, 21). The bore 38a and the elongated hole 39a are here aligned vertically in the Z direction (in the usual installation position on a drawer, the vertical direction). The elongated hole 39a is also oriented vertically here and lies here in the vertical direction (Z) below the bore 38a.

On the upper locking device 14b, the one - here upper - end 36 of the upper spiral spring 28b of the upper energy store penetrates an elongated hole 39b and the other - here lower - end 37 on the other hand a bore 38b of the base plate arrangement (here the two base plates 20, 21). The bore 38b and the elongated hole 39b here are aligned vertically in the Z direction (in the usual installation position on a drawer, the vertical direction). Here, both slots 39a, b and both holes 38a, b are even aligned.

The lower end 37 of the lower spiral spring 28a of the lower spring element 26a also passes through a bore 40a of the lower release lever 24a, which is in the vicinity of the upper end (in the Z direction) of the lower release lever 24a.

The lower end 37 of the lower spiral spring 28a of the lower energy accumulator 26a thus serves as an axis of rotation / shaft for the lower release lever 24a, which can rotate about the free end 37 of the spiral spring 28a, which in turn can move in the elongated hole 39a. In this way, the trigger lever 24a can carry out a superimposed rotary and translational movement on the base body, here the base plate arrangement.

The free lower end 37 of the lower spiral spring 28a also passes through a bore 41a located in the lower region of the lower catch lever 25a, this catch lever also being able to carry out a superimposed rotational and translational movement on the base plate arrangement. The lower catch lever 25 also has an elongated hole 42a which lies above the bore 41a. This elongated hole 42a is penetrated by the other - here upper - free end 36 of the lower spiral spring 28a. In this way, the lower catch lever 25a (similar to Figures 1-10 ) to a defined rotational and translational movement (to be described in more detail) when the lower free end 37 of the lower spiral spring 28a moves in the elongated hole 39a of the base plate arrangement, which also moves the lower catch lever 25a.

The upper end 36 of the upper spiral spring 28b does not pass through the release preventer 24b. However, the free upper end 36 of the upper spiral spring 28b passes through a bore 41b of the upper catch lever 25b. This can also perform a superimposed rotary and translational movement on the base plate arrangement. The upper catch lever 25b also has an elongated hole 42b, which lies below the bore 41b.

This elongated hole 42b is penetrated by the other - here lower - free end 37 of the upper spiral spring 28b. In this way, the upper catch lever 25b is also forced to perform a defined rotational and translational movement (to be described in more detail) when the lower end 37 of the upper spiral spring 28b moves or can move in the elongated hole 39b of the base plate arrangement, which entrains the upper catch lever 25b .

If the free lower end 37 of the lower spiral spring 28a is located at the upper end of the elongated hole 39a of the base plate arrangement, this spiral spring 28a is tensioned. This position corresponds to a position in which the front panel 7b is not yet fastened (see for example Fig. 14 ). Furthermore, if the free upper end 36 of the upper spiral spring 28b is located at the lower end of the elongated hole 39a of the base plate arrangement, this spiral spring 28b is tensioned. This position again corresponds to a position in which the front panel 7b is not fastened ( 11 to 16 ).

If, on the other hand, the other end of the respective spiral spring 28a or 28b is located at the other end of the elongated hole 39a or 39b of the base body, here the base plate arrangement, the respective spiral spring 28a and / or 28b is in a more relaxed state. This position corresponds to a position in which the front panel 7b has been attached ( Fig. 17 ).

Each of the two catch levers 25a, 25b has a hook-like locking end 43a, b, which is designed to then engage behind the undercut, here the bolt 18a or 18b, which then in each case in a horizontally extending slot 44a, b of the base plate arrangement is introduced, which is open in the direction of the front panel 7b.

So that the spiral springs 28a, b can be held in the tensioned position and so that they can be released therefrom and also the spiral spring 28a, b can be moved from the relaxed position to the tensioned and back, the coupled, here articulated coupled elements lower trigger lever 24a and upper trigger preventer 24b are provided.

The upper release preventer 24b is pivotally mounted with the pin 62 on the base body, here the base plate arrangement. The energy storage device assigned to it, here the spring 63, presses it in the direction of the front panel 7b. The lower end 67 of the upper release lever 24b acted upon by the spring 64 acts in this case (see, for example, FIG Fig. 14 ) on the upper catch lever 25b.

This lower end 67 is designed such that the upper catch lever 25b can be locked in such a way that the upper slot 44b is exposed. If an upper connecting fitting 15b is now moved to the frame 8, the upper release preventer 24b is pivoted away from the panel 7b against the force of the spring 63. As a result, the upper release preventer 24b is released in such a way that the upper energy accumulator 26b can act on the upper catch lever 25b and move it, so that the upper connecting fitting 15a is pulled towards the frame 8 ( Fig. 16a , Fig. 19 ) and is locked.

The lower release lever 24a is (as described) pivotally mounted on the base body, in particular the base plate arrangement. The trigger preventer 24b does not act on the lower locking or catching device 14a here. The lower safety gear can always trip. The release preventing device 24 ensures that the upper locking or catching device only releases when a bolt is in position at the top. Only the release is coupled.

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

If a lower connecting fitting 15a is now inserted into the lower slot 44b on the front panel 7b ( 15 to 16 or 18th , the lower release lever 24a is moved by the lower connecting bracket 15a and also pivoted. As a result, the lower release lever 24a is pivoted out of the over-dead center position, so that the lower spring arrangement 26b is released, so that the lower connecting fitting 15a is also pulled onto the frame 8.

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

As an alternative, the lower release lever 24a and the upper release lever or prevent 24b can also be actuated or triggered one after the other in this way, in particular if the front panel 7b is oriented obliquely at an angle to the front frame edge or to the Z direction ( Fig. 18 , 19th ). The lower connection fitting 15a can either be inserted into the lower locking device 15a first ( Fig. 18 ) or the upper connection fitting 15b into the upper locking device 15b ( Fig. 19 ).

The arrangement is such that if the lower connecting fitting 15a is first inserted into the lower slot 44a and then the upper connecting fitting 15b into the upper slot 44b, the lower locking device 14a is triggered first and then the upper locking device 14b ( Fig. 18 ).

The upper release preventer 24b directly holds the upper catch lever 25b in a stable blocking position due to the construction, when loaded by the force (from the spring 63).

If the lower connecting fitting 15a or its bolt 18 is inserted into the lower slot 44, the edge of this connecting fitting 15a facing the lower locking device 14a reaches the lower release lever 24a, so that it is pivoted rearward from the over-dead center position. In this way, the lower locking device 14a can be triggered, so that the lower catch lever 25a locks the lower connecting fitting 15a. By turning the lower trigger lever 24a, the coupling lever 60 is also pivoted (see also Fig. 18 ). If the upper connection fitting 15b is then or simultaneously inserted, its bolt 18b strikes the release preventer 24b in the slot 44b and pivots it.

As a result, the upper locking device 14b is also moved into its locking position, which also locks the upper connection fitting 15b on the upper locking device 14b.

If, on the other hand, the upper connecting fitting 15b is first inserted and then the lower connecting fitting 15a, the upper locking device 14b only triggers when the lower locking device 14a ( Fig. 18 ) has triggered. The latter is only released after the lower connection fitting 15a has been pushed in. The trigger preventer 24b is already pivoted at the top when the upper connection fitting 15b is inserted. In this position, however, the lower release lever 24a holds the upper catch lever 25b in the open position via the vertically oriented coupling lever 60. Only when the lower connection fitting 15a is also pushed in and the lower release lever 24a is pivoted is the coupling lever 60 also released from the stable vertical position, so that the upper connection fitting 15b is correspondingly locked on the upper locking device 14b.

The lower trigger lever 24a in turn has a torque transmission contour 45. Here, this is again not intended for direct manual movement, but for attaching a corresponding tool (exemplary training: Phillips and screwdriver). With the lower release lever 24a, the lower locking device 14a is released and then, or also via the coupling lever 60, also the upper release preventer 24b and thus the upper one of the locking devices 14b.

Overall, this creates a very compact and yet safe locking fitting for high panels.
