Abstract

The invention relates to a fixing device (10) for fixing a panel (2) of a drawer (1) to a panel structure (4a, 4 b). The fastening device (10) has at least one holding element (101, 201) arranged on the panel side and at least two catch devices (100, 200) arranged on the panel structure side. For locking purposes, the catch devices (100, 200) are mechanically coupled together in a functionally effective manner, such that the catch devices (100, 200) can be locked together to the at least one holding element (101, 201); and for unlocking purposes, the two catch devices (100, 200) are mechanically functionally separated so that the unlocking process is performed by actuating the respective catch devices (100, 200) separately.

Description

Fixing device for drawer panel

Technical Field

The invention relates to a fastening device for fastening a panel of a drawer to a frame, wherein the fastening device has a holding element that can be arranged on the panel side and has at least two catch devices arranged on the frame side.

Background

DE 9421872U 1 describes a fixing device for fixing a front panel of a drawer to a drawer frame. In addition to the retaining spring, the fastening device also has a locking device which functions in a self-locking, non-rigid or clamping manner according to fig. 15 and in a rigid locking manner according to fig. 21. In this way a safety function will be achieved, thereby safely preventing accidental release of the device-e.g. due to very large stresses caused by shaking movements or the like.

EP 2747599 a discloses the use of two or more catch devices arranged on top of each other in a relatively high drawer. Therefore, it is necessary to lock and release the two catch means separately to lock and release the panels with respect to the respective frames, or to lock and release them simultaneously.

The former of these solutions is more time-consuming in terms of actuation, while the second solution requires the implementation of a mechanically relatively complex coupling mechanism between the two catch means, which on the one hand is usually relatively expensive, and on the other hand has the disadvantage that the actuation force during unlocking is relatively high, since the catch means must usually be moved from the locked position to the unlocked position with only a single actuation overcoming the mutually exerted spring force of the two securing means.

Disclosure of Invention

The aim of the invention is to achieve a solution to this problem that is easy to implement in terms of design and at the same time easy to handle and functionally reliable.

The invention solves this problem by the subject matter of claim 1 and the methods according to claims 17 and 18.

Advantageous embodiments of the invention can be found in the dependent claims.

The feature according to claim 1, that for locking purposes the catch means are mechanically coupled to each other in a functionally effective manner, so that the catch means can be locked together on the respective holding element-by one application or one actuation. In contrast, for unlocking, the two catch means are not coupled to each other in a mechanically functionally effective manner, i.e. they are mechanically separated, so that unlocking is or has to be performed by individual actuation of the two catch means. In other words, the two catch means have a mechanically effective connection when locked, whereas they are not mechanically effective connected when unlocked, but have to be actuated-released separately.

This has the advantage that the force required for release is much smaller compared to a design where the two catch means are moved together into the release position by only one single actuation, because in case of a design where the two catch means are moved together into the release position by only one single actuation, the two catch means will have to be released against the action of the two spring means by only one single actuation movement.

On the other hand, if the two catch means are actuated separately, the release is preferably made separately at different times against the action of only one of the spring means at a time. Although the release for each frame takes longer-usually only a few seconds-it is much easier to perform. On the other hand, the locking can be performed simply by applying a single movement of the panel to the frame.

The features of claim 1 are furthermore advantageous, since, from a design point of view, only the kinematic coupling for locking has to be implemented, and not the kinematic coupling for releasing, which would make the assembly of the device consisting of two catch means significantly more complicated.

According to a first variant, it may be provided that, on one or both catch means, the respective catch means are locked in the catch position only as a result of a partial displacement of the axis of rotation of the catch means. With a catch device operating according to this working principle, the invention can be implemented particularly easily in terms of design.

For implementation in terms of construction, it can be advantageous and simple to provide the release element such that the release element is rigidly coupled to the catch element of one catch device both during unlocking and during locking, and such that the release element is rigidly coupled to the catch element of the other catch device only when locked.

If the catch element is locked in the catch position on one or both catch devices as a result of a local displacement of the axis of rotation of the catch element, it is advantageous if the rotational movement or pivoting of the respective catch element about its axis of rotation is superimposed or preceded or followed by a movement of the axis of rotation which locally, preferably linearly, displaces the axis of rotation. Such a defined displacement of the rotational axis position can be achieved in particular by displacing a central axis of a shaft section or a bolt or the like, with or on which a catch element of the catch means is pivotably mounted. In this case, the position is shifted into a catch position, which is selected such that an additional locking effect is produced as a function of the shift of the axis of rotation.

It can advantageously be provided that the direction of movement of the axes of rotation of the two catch elements when they are displaced is perpendicular or substantially perpendicular to the direction of movement of the holding element when the holding element is locked onto the catch means.

In order to achieve a well-functioning interlock, it can furthermore be provided that the displacement of the respective axis of rotation is implemented such that, in the catch position, it is located in the Y direction perpendicular to the main direction of extension of the frame or close to the Y direction of the central axis of the retaining bolt of the retaining element. It can be realized that, in the locked or interlocked state of the catch means, the instantaneous axis of rotation of the catch element can preferably lie just below or above the effective plane or on the effective plane of the retaining element (in particular the retaining bolt of the retaining element on the panel). The effective plane is defined by a plane defined between the X-axis and the Z-axis, which runs parallel to the base of the frame. This means that, by the opening movement of the drawer, with the accompanying force exerted on the front panel, only a small amount of torque or even no torque at all can be exerted on the catch element, so that advantageously it is practically impossible to overcome the locking mechanism by the opening movement of the drawer alone. Thus, no additional, for example rigid latching latches for holding the catch element in the holding position or clamping action for holding the holding element are required.

In a preferred embodiment variant of the invention, the drive geometry for the tool is integrated into a catch element of a catch device. The drive geometry interacts with the tool in a simple design and production-related manner and is therefore advantageously used for the unlocking and return possibilities of the catch element. On the other hand, on the other catch device, the drive mechanism is not integrated into the catch device, but into a release element assigned to the catch device.

In a preferred embodiment variant of the invention, the displacement of the respective axis of rotation is defined by the guide cam and the slotted connection. This results in a defined displacement of the axis of rotation, which is easy to implement in terms of production technology and is therefore advantageous.

It can advantageously be provided that the displacement of the axis of rotation of each catch element is defined by a mechanical control device which correlates the displacement of the axis of rotation with the pivot position of the catch element. In this way, a precise and defined movement into the catch position and out of the release position is achieved. It is simple and safe in terms of design if the mechanical control device is formed by a corresponding transmission. Thus, according to an advantageous design, the transmission means may comprise the transmission means of the catch means and the corresponding transmission means of the base element.

For example, the gear of each base element can be designed in a simple and advantageous manner as a linear gear, preferably as a toothed rack, which is arranged or formed on the base element.

In a further preferred embodiment variant of the invention, the respective displacement of the axis of rotation of the catch element is supported by rolling the drive of the catch element on the drive of the base element. In this way, the displacement of the axis of rotation is supported in a reproducible and therefore advantageous manner by simple kinematics. The drive of the base element can be designed in a simple manner as a linear drive, for example as a toothed rack, which is arranged or designed on the base element.

It is further advantageous if a mounting base is provided for mounting the two catch means. In terms of design, it can advantageously be provided that the mounting base has an overlapping housing for the two catch devices, which housing is formed by a first half-housing and a second half-housing, wherein at least the catch element and the release element are arranged in the housing.

The housing in which the catch element is safely accommodated is simply and advantageously formed. Furthermore, the slotted connection can be easily formed in this way for production purposes.

In a particularly preferred variant, at least one half shell is directly connected to a wall surface of the frame. However, this is not absolutely necessary, but is merely a constructive option.

In a further preferred embodiment variant of the invention, the holding element comprises a holding part which is attached to the base part and can have a U-shaped cross-sectional geometry, wherein the U is dimensioned such that the clear width of the U is greater than the width B of the housing, and a holding bolt. This simply and advantageously ensures that the retaining bolt can engage in the cutout of the catch element without interfering with the contour.

In a further preferred embodiment of the invention, at least one of the holding elements has at least one adjusting device. This ensures, with a simple and advantageous design, an adjustment of the relative position of the panel in the vertical and/or horizontal direction and/or the tilting direction with respect to the frame.

In a further preferred embodiment variant of the invention, the catch element can have a semicircular recess in which the geometrically identical, circularly integrally formed end of the guide element of the energy storage device, in particular of the spring device, engages. This creates a pivot joint through which the spring means is operatively connected with the catch member. Due to the pivot joint, the spring means always advantageously acts on the catch element without a bending moment.

In a further preferred embodiment variant of the invention, the two holding elements can be combined into a holding module by a continuous, preferably integral base, wherein the two holding parts are attached to the continuous base. The continuous one-piece base produces an advantageously simplified assembly of the retaining elements, which thus combine to form the retaining module. Preferably, the two retaining bolts are vertically spaced above each other.

Method according to claim 17, the panel being fixed by a single application movement, wherein the two catch means are released one after the other with a delay and engage with at least one retaining element, in particular two retaining bolts.

Method according to claim 18, the catch means being disengaged separately for releasing from the at least one holding element, in particular two holding bolts.

This method therefore supports the advantageous idea that, from a design point of view, only the coupling for locking has to be realized, without the need to realize a kinematic coupling for release that would make the assembly of the device consisting of two catch means significantly more complicated.

Detailed Description

Terms such as "upper", "lower", "right" or "left" refer to respective positions indicated in the drawings, and should be understood or observed with respect to movement, particularly rotation, in space of the indicated elements.

Fig. 1 and 2 each show one half of a drawer 1 in different views. The drawer 1 has a panel 2, a bottom panel 6 (shown only in fig. 2) and preferably a rear panel 3. The drawer 1 also has a first left frame 4 and a second right frame (not shown here).

The frame 4 shown here has a fastening device 10 with two

catch devices

100, 200 arranged vertically above one another. The second frame (not shown, but preferably provided) of the drawer 1 may be constructed in the same manner. However, for the sake of simplicity, only one of the frames 4 is shown and described below.

There is provided a fixing means 10 for fixing the panel 2 of the drawer 1 to each frame 4-see also fig. 4 and 5-wherein the fixing means 10 has at least one or two one-or

multi-piece retaining elements

101, 201 which may be arranged on the front panel side and two catch means 100, 200 which may be arranged on the frame side. Preferably, the two holding elements 101, 201 (see fig. 4) can be designed separately and can be fixed to the panel 2 individually or connected to each other and fixed to the panel 2 as an overlapping stack unit (see fig. 27). They are preferably arranged vertically to one another on the panel or are designed to be spaced apart from one another.

The

catch devices

100, 200 may be locked to the respective one or

more holding elements

101, 201 to connect the panel 2 to the respective frame (called locked position, see fig. 5). They can be released from this locking position (called release position, see fig. 11, then 12), thus separating the panel 2 from the respective frame 4.

The frame 4 may, for example, be made of a metal material (for example sheet metal) and has a cavity into which the catch means 100, 200 of the fixing means 10 of the panel 2 of the drawer 1 are inserted. However, these

catch devices

100, 200 can also be arranged on the drawer frame 4 in a different manner. The

respective holding element

101, 201 is arranged on the front panel and is fixed in a fixed or adjustable manner, for example screwed in. It can also engage in a cavity of the frame 4, which is preferably aligned at right angles to the panel in the catch position.

In order to be able to actuate, in particular unlock and release, the

respective catch devices

100, 200, the frames 4 may each have a cut-out 5a, 5b, which cut-

outs

5a, 5b may optionally be covered by a cover or an overlapping cut-out (not shown), through which cut-

outs

5a,

5b catch devices

100, 200 inserted into the respective frames 4 are accessible and actuatable from the outside.

The two

catch devices

100, 200 are coupled together in a mechanically functionally effective manner to lock and reach a locked position so that they can be locked on the

respective holding element

101, 201 by a single application movement of the panel. On the other hand, for unlocking and reaching the release position, the two

catch devices

100, 200 are not coupled to each other in a mechanically functionally efficient manner, so that unlocking is performed by individual actuation of the two

catch devices

100, 200.

This design is described below using a preferred embodiment. For this purpose, the function of the fastening device 10 with only one catch device must first be explained.

Fig. 19 shows a fixing device 10 for fixing a panel 2 of a drawer to a frame 4, the panel 2 of the drawer having a height smaller than that of fig. 1, the frame 4 having a correspondingly smaller height. The fixing device 10 has a panel-side holding member 101 and a single frame-side catch device 100. The catch device 100 has catch elements 116 which are pivotably mounted on the respective frame.

The catch element 116 can be subjected to a force by an energy storage device, in particular a spring device 104, and can be moved between a release position and a catch position, and in the catch position holds the holding element 101 of the panel to the frame 4.

The catch device 100 of fig. 19 has a mounting base with a base element 102. The base element 102 may be formed by an element of the frame 4 itself. However, it may also be formed by at least one separate element fixed to the frame 4, for example an element inserted into a cavity of the frame 4 and fixed to the frame 4. The base member 102 may be formed as at least one plate. The base element 102 serves for arranging the energy storage device and also serves as a support for the energy storage device. The energy storage device is preferably designed as a spring device. Therefore, in the following the term "spring means" is used, which in the following and also in the claims comprise different types of energy storage means.

In this case, the spring means 104 comprises a compression spring. Alternatively, the spring device 104 can also have another spring of a different design. The spring means 104 also has a guide element 105. The guide element 105 is here mounted movably in the holding bracket 103. The guide element 105 may have a stop 106 for the compression spring 104. The compression spring of the spring means 104 is arranged between the holding bracket 103 and the stop 106.

The catch device 100 can have a housing 108, which housing 108 has a first right half-shell 107a and a second left half-shell 107b extending parallel thereto as a further supplement to the mounting base or as a mounting base altogether.

Here, the

housing halves

107a, 107b are joined together (in this case with rivets) to form the housing 108. The

half shells

107a, 107b are made of a metallic flat material, for example a steel plate. Alternatively, the

half shells

107a, 107b can also be made of another material, for example aluminum or plastic. A gap or slit may be formed between the housings for accommodating one or the necessary functional elements of the two

catch devices

100 and 200 according to fig. 1 to 18.

The mounting base, here the housing 108 with the base element 102, may have at least one slotted connection 109, in which slotted connection 109 the guide cam 110 is slidably mounted. Here, the

half shells

107b, 107a each have a slotted connection 109, and the guide cam 110 is slidably mounted in this slotted connection 109. Furthermore, here, the one second left half-shell 107b can have a recess 111. Through this recess 111, a curved slotted hole 112 is visible, which is introduced into the first right half shell 107 a.

The two half-

shells

107a, 107b each have a geometrically identical, groove-

like cutout

114a, 114 b. In the locked position of the catch device 100, the cut-

outs

114a, 114b are penetrated by a holding bolt 115 (in a horizontal position) of the holding element 101 (see fig. 19). Furthermore, in the locked position, the catch elements 116 are each engaged in the cutout 114.

Fig. 19 also shows a retaining element 101 in an exemplary design. The holding element 101 has a base 117, by means of which base 117 the holding element 101 is attached to the panel 2 of the drawer 1. The holding element 101 also has a holding portion 118, which holding portion 118 is attached to the base portion 117 and has a U-shaped cross-sectional geometry. U is sized such that the clear width of U is greater than the width B of the housing 108. The holding portion 118 has two

notches

119a, 119b which are arranged in pairs and guide or fix the panel in the horizontal direction on the housing 108 when or after the holding portion 118 is locked. In order to adjust the relative position of the panel 2 with respect to the frames 4a, 4b in the vertical direction, the respective holding element 101 may have an adjustment device 120.

If the two

catch devices

100, 200 are arranged on top of one another, two

such retaining elements

101, 201 can be arranged on top of one another on the panel 2 or a retaining element 101 with two retaining bolts can be arranged on the panel 2 (fig. 27).

In fig. 20, the catch device 100 is shown without the left half-shell 107 b. Thus, the catch member 116 is clearly visible. The catch element 116 has a gear 121. The base member 102 also has a transmission 122. The two

gear mechanisms

121, 122 mesh with each other and are therefore operatively connected to each other. The

gears

121, 122 are preferably involute gear teeth. Other transmissions are also contemplated. The centre planes of the catch element 116, the gearing of the base element 102 and the compression spring 104 all lie in one plane in the longitudinal direction of the frame, which is why the width B of the housing with parallel half shells can be less than 8mm and, in particular, all forces can be released in one plane without generating tilting moments if possible.

The catch element 116 has a semicircular recess 123, in which semicircular recess 123 a geometrically identical, circularly integrally formed end 124 of the guide element 105 of the spring device 104 engages. This creates a pivot joint. The spring device 104 is thus operatively connected to the catch member 116. Due to the pivot joint, the spring device 104 advantageously acts on the catch element 116 with a bending moment which is as small as possible.

The catch element 116 also has a slot-like cutout 125. The boundaries of the slits 125 parallel to each other are preferably formed in a curved manner. The dimensions of the cutout 125 are selected such that the retaining bolt 115 of the retaining element 101 can be passed through the cutout 125 in the horizontal direction with little play at any time. The hook 127 in the catch element 116 is formed by the cut-out 125.

Also shown is a guide cam 110, which guide cam 110 is guided in a slotted connection 109 (also not shown here) of the left half shell 107b (also not shown here). The same guide cam 110 is guided in a slotted connection 109 of the right half-shell 107a (also not shown here). A cylindrical shaft section 126 may be formed between the two guide cams 110. The catch member 116 may preferably be pivotally mounted on the shaft segment 126.

The drive geometry 113 can also be seen, which drive geometry 113 is embedded in the catch element in a region in the form of a cross recess. The drive geometry 113 in combination with a corresponding actuating tool (here a phillips head screwdriver) serves as an unlocking and return possibility for the catch element 116. The tool passes through the drive geometry 113 and is engageable at least in the slotted hole 112 of the first right housing half 107 a.

The slotted hole 112 thus serves as a free space for the screwdriver tip, so that a reliable rigid connection between the drive geometry 113 and the screwdriver tip is achieved. Other drive geometries 113 than the cross recess shown here are also conceivable.

Fig. 21 to 25 show a locking process of the card grab device 100 for locking a panel in different sequential steps or increments (incriments).

In fig. 21, the catch device 100 is shown, wherein no frame 4 surrounds the catch device, but wherein the holding element 101 is in a basic position in which the catch device 100 is open.

In fig. 22, the catch device 100 is shown in the following position: in which retaining bolts 115 engage in

cutouts

114a, 114b, each formed by the two half-

shells

107a, 107b, and are in contact with catch elements 116. The

recesses

119a, 119b of the retaining part 118 have been placed on the two

half shells

107a, 107b (only 107a is shown here) such that the retaining bolt 115 engages centrally in the cut-

outs

114a, 114 b. The retaining portion is recessed on one of its legs so that the retaining bolt 115 is visible.

The catch element 116 has moved out of its initial position shown in fig. 21 and, by the movement of the retaining bolt 115 on the catch element 116, has been rotated partially clockwise about the shaft section 126 and has displaced the effective line of the spring force to some extent, so that an automatic rotational movement of the catch element 116 takes place, wherein the spring force of the spring element 104 or the force stored in the compression spring supports the movement of the retaining bolt 115 into the

cutouts

114a, 114 b. This movement is possible because the central axis of the retaining bolt 115, which is at a vertical distance from the instantaneous position of the central axis of the shaft section 126, acts on the catch element 116, so that a torque acting in the clockwise direction is exerted on the catch element 116.

The drive 121 of the catch element 116 has already rolled off (roloff) to some extent on the drive 122 of the base element 102. Due to the rolling movement, the shaft section 126 and thus the instantaneous axis of rotation of the catch element 116 have been moved vertically downwards to some extent by a guide cam 110 which is integrally formed on the shaft section 126 and is displaceably guided in the slotted connection 109.

In fig. 23, the catch device 100 is shown in a position in which the retaining bolt 115 engages in the cut-

outs

114a, 114b and in which the cut-outs 125 or hooks 127 of the catch element 116 engage with the retaining bolt 115. Due to the spring force of the spring element 104 or the force stored in the compression spring, the catch element 116 has completed a further partial clockwise rotation about the shaft section 126 compared to fig. 22.

In this case, the gear 121 of the catch element 116 has rolled off further on the gear 122 of the base element 102. Due to the rolling movement, the shaft section 126-and thus the instantaneous axis of rotation of the catch element 116-has been moved slightly further vertically downwards by the guide cam 110 which is integrally formed on the shaft section 126 and displaceably guided in the slotted connection 109, compared to fig. 22.

In fig. 24, the catch device 100 is shown in a position in which the retaining bolt 115 is engaged in the cut-

outs

114a, 114b and in which the cut-out 125 or the hook 127 of the catch element 116 has pulled the retaining bolt 115 and thus the retaining element 101 further into the cut-

outs

114a, 114 b. This causes the panel 2 (not shown here) to be pulled further to the respective frame 4a, 4b of the drawer 1. Due to the spring force of the spring element 104 or the force stored in the compression spring, the catch element 116 has again already made a further partial clockwise rotation about the shaft section 126, in comparison with fig. 23.

The gear 121 of the catch element 116 rolls down further on the gear 122 of the base element 102. Due to the rolling movement, the shaft section 126-and thus the instantaneous axis of rotation of the catch element 116-has been moved slightly further vertically downwards by the guide cam 110 which is integrally formed on the shaft section 126 and displaceably guided in the slotted connection 109, compared to fig. 23.

In fig. 25, the catch device 100 is finally shown in a locking end position, in which the retaining bolt 115 engages in the cut-

outs

114a, 114b and the retaining bolt 115 is located at the bottom of the cut-out 125. Thus, the panels 2 (not shown here) have rested on the respective frames 4a, 4b of the drawer 1 and are locked against accidental release.

Due to the spring force of the spring element 104 or the force stored in the compression spring, the catch element 116 has already undergone a further partial clockwise rotation about the shaft section 126, up to a possible end point, in comparison with fig. 8.

The gear 121 of the catch element 116 rolls down further on the gear 122 of the base element 102. Due to the rolling movement, in contrast to fig. 9, the shaft section 126-and thus the instantaneous axis of rotation of the catch element 116-is moved slightly further vertically downwards to the lower end point of the slotted connection 109 by means of a guide cam 110 which is integrally formed on the shaft section 126 and is slidably guided in the slotted connection 109.

The current axis of rotation of the catch element 116 and/or the center axis of the shaft section is therefore now located just below the effective plane a and/or on the effective plane of the retaining bolt 115 in the

cutouts

114a, 114 b. This means that, by the opening movement of the drawer 1, with the accompanying force exerted on the panel 2, only a small or no torque can be exerted on the catch element 116, so that overcoming the locking mechanism by the opening movement of the drawer is advantageously virtually impossible.

Furthermore, the catch element 116 already rests against the base element 102, so that a further clockwise rotation of the catch element 116 is not possible.

The locking of the retaining bolt 115 is thus achieved by a defined displacement of the central axis of the rotational axis or shaft section 126, on which the catch element 116 is pivotally mounted. This displacement is defined by the guide cam 110 and the slotted connection 109 and is supported by the rolling of the actuator 121 of the catch element 116 on the actuator 122 of the base element 102.

The catch device 100 can only be unlocked by a rotational movement of the catch element 116 against the rotational locking direction, which is initiated by a tool inserted into the drive geometry 113. In this case, the spring force of the spring element 104 must be overcome. Instead of the tool used, the drive geometry can also be designed such that it can be actuated manually without a tool.

Fig. 26 shows the card-catching device 100 without the holding element 101 in a spatially exploded view. It can be clearly seen that the shaft section 126, on which the catch element 116 is pivotably mounted, and the two guide cams 110, which are formed integrally with this shaft section 126.

In the case of a high drawer 1 with a high panel 2 and a high frame 4-in the embodiment shown-on both

catch devices

100, 200 substantially this design of fig. 19 to 25 is used.

The corresponding elements of the two

card grasping devices

100, 200 differ by the first digit of the reference numeral, which starts with a "1" for the lower card grasping device 100 and a "2" for the upper card grasping device 200. In the case of elements used by both of the

card grasping devices

100, 200, they are then labeled "1".

This means that the housing 108 with the two

housing halves

107a, 107b can be used for both card gripping devices 100 and 200 (see fig. 18 as well as fig. 4 and 5). A

base element

102, 202 may be provided for each of the

card grasping devices

100, 200, respectively.

Preferred configurations of the upper and lower

card grasping devices

200, 100 are described below. The function of the upper card-grasping device 200 may also be interchanged with that of the lower card-grasping device 100. For this purpose, only a mirror-symmetrical design of the catch device needs to be realized.

Here, the two

catch devices

100, 200 are further designed and arranged such that the design of the lower catch device 100 essentially corresponds in principle to the arrangement of fig. 19 to 25, such that during locking, the catch element 116 is turned such that the cut-out 125 engages on the retaining bolt 115 from top to bottom; while the upper catch means 200 are constructed so that during locking from the bottom up, the cut-out 225 of the upper retaining element 216 engages on the upper retaining bolt 215. In this way, the functional coupling during locking is particularly easy to achieve. The arrangement shown can also be used on a "head" rotated 180 ° to lock the panel. In the following, the function of the device consisting of the two

catch devices

100, 200 is described in more detail with reference to fig. 5 to 18.

Fig. 5 shows two

catch devices

100, 200, each in a final locked position, so that the panel 2 is firmly attached to the respective frame 4.

The respective retaining

bolts

115, 215 project into the respective cutouts 114, 214 (see also fig. 18). Thus, the panel 2 (not shown here) has rested against the respective frame 4a, 4b of the drawer 1 and is locked against accidental release.

This is because the current axis of rotation of the

respective catch element

116, 216 lies exactly outside the respective effective plane a, a' — here below at the bottom and above at the top-or on the effective plane of the retaining

bolt

115, 215 in the

cutout

114a, 114 b. Thus, by the opening movement of the drawer 1, with the accompanying force exerted on the panel 2, only a small or no torque is exerted on the

respective catch elements

116, 216, so that it is advantageously virtually impossible to overcome the locking mechanism by the opening movement of the drawer 1 alone.

The two

catch devices

100, 200 of the fastening device 10 differ in their configuration on the one hand with respect to the arrangement of the

catch elements

116, 216 and on the other hand with respect to some other constructional details.

The design of the lower catch device 100 here corresponds almost exactly to the design of fig. 19 to 25. However, in the mounted position with respect to the bottom panel 6 of the drawer 1, an edge recess 130 is provided at the upper edge of the lower catch member 116. Here, by way of example, it has a trapezoidal shape.

In one aspect, the upper catch means 200 has the opposite functional orientation as the lower catch means described above.

Then, a release element 230 (a kind of "release lever") is assigned to the catch element 216 of one catch device 200 (here the upper catch device).

The release member 230 is located just below the upper catch member 216 between the lower catch member 116 and the upper catch member 216. The release element 230 has a drive geometry or actuation profile 231 for applying an actuation tool. The actuating tool may be designed as a screwdriver with a corresponding torque transmission profile.

In a preferred design, the release element 230 is located between the two

half shells

107a, 107b and between the two

catch elements

116, 216, whereby the torque transmission profile is accessible through an arc-shaped slotted connection 232 in the housing 208 (preferably in both half shells). The slotted connection 232 is designed such that it allows the application of an actuating tool, so that the release element 230 can be moved together with the actuating tool in the slotted connection 232.

The release member 230 and the upper catch member 216 are mated with each other such that the upper catch member 216 can be moved with the release member 230 from the locked position to the unlocked position, particularly within a stacked linear and pivotal frame of movement, by actuating the release member 230. The release element 230 is in contact with the catch element 216 via the drive contour 233.

Fig. 5, 6 and 7 show how the release element 230 can be moved in the slotted connection 232 from right to left by an actuating tool (not shown here), as a result of which the catch element 216 is moved downward at its drive 121 at the corresponding drive 122 of the base element 212 and is finally pivoted clockwise until the cutout 225 of the catch element 216 finally releases the retaining bolt 216 of the upper retaining element 201 (fig. 5, 6, 7, 8 and 18). Thus, the upper card grasping device 200 has been moved to the release position (see fig. 8).

The lower catch element 116 is then moved in a similar manner at its drive contour 113 by the actuating tool from the locked position (fig. 8), wherein a separate further movement and actuation takes place into the unlocked position. In this case, the lower catch member 116 pivots counterclockwise and moves upward at the gear 121 until the cutout 125 of the lower catch member 116 finally releases the retaining bolt 116 of the lower catch member 116 (fig. 8 to 11). This also moves the lower and upper card-grasping

devices

100 and 200 together to the release position (see fig. 11).

This means that the two

catch devices

100, 200 are mechanically and functionally moved completely independently of each other by a single actuation from the locking position to the release position.

In the sense of claim 1, the two

catch devices

100, 200 are thus unlocked in a preferred and advantageous-but not necessarily so-design without being mechanically and functionally effectively coupled to one another, so that unlocking is achieved by individual actuation of the two catch devices.

On the one hand, this has the advantage that the force required for release is much smaller compared to a design in which the two

catch devices

100, 200 are moved together into the release position by only one single actuation, since in the case of a design in which the two

catch devices

100, 200 are moved together into the release position by only one single actuation, the action of the two spring means 104, 204 would have to be overcome by only one single actuation movement to release the two catch devices. However, in case of actuation of the two

catch devices

100 and 200, respectively, the release is done separately and only the action of one of the

spring devices

104 and 204 is counteracted at a time.

On the other hand, it is advantageous that, from a design point of view, it is not necessary to implement a corresponding kinematic coupling that would make the assembly of the device constituted by the two catch means more complex.

The release member 200 may be arranged in a limited movement, particularly pivotable on the upper catch member 216. This is achieved here by: one of the release elements 230, here the upper end, engages in a puzzle-like manner with a partially rounded head as a drive contour 233 in a correspondingly shaped recess 234 of the catch element 216, so that the release element 230 can be pivoted on the upper catch element 216 at a limited angle relative to the upper catch element 216. A spring 235, for example a V-shaped leaf spring, may be arranged between the upper catch member 216 and the release member 200, by means of which spring the lower end of the release member is pressed away from the upper end of the catch member 216.

In the release position of fig. 9, after removal of the actuating means, the release member 130 is pivoted downwards essentially by the action of the spring 235. In the release position of fig. 12, the lower projection 236 of the release member 130 extends into the edge recess 130 of the lower catch member 116. In this way, a rigid connection is achieved between the release element 230 of the upper catch device 200 and the catch element 116 of the lower catch device 100.

In this way, the

catch devices

100, 200 are coupled together in a mechanically and functionally effective manner for locking, so that they can be locked together on the respective retaining element by a single actuation, here a single application movement of the panel 2.

This is because this design makes the lower catch member 116 automatically pivot to the locking position by the lower spring member 104 when the lower retaining bolt 115 is triggered when the panel 2 is attached. The rigid connection between the lower catch member 116 and the release member 230 via the release member 230 also triggers the rotation of the upper catch member 216, which releases the spring 205 and guides it to the locked position.

This is possible because the upper catch element 216 is designed such that the upper retaining bolt 215 can be guided into the cutout 214 of the housing 108 up to a position corresponding to its locking position (see fig. 13), without touching the catch element 216. For this purpose, the outer circumferential contour of the upper catch element 216 is designed such that it is also at a distance from the upper retaining bolt 215 in this position. Therefore, the upper retaining bolt 215 cannot actuate the catch element 216 and does not trigger the locking process.

On the other hand, when the lower holding bolt 115 is inserted into the lower catch device at this insertion depth, the lower catch device 100 is caused to be triggered (fig. 14). Furthermore, a respective retaining lug 237, which projects into the cutout (114, 214), is integrally formed on at least one of the

half shells

107a, 107 b. The retaining lug 237 can be used to pre-position the retaining

bolt

115, 215 and thus the panel 2 on the frame 4, so that, for example, the panel 2 can be prevented from falling out after unlocking the

catch device

100, 200. Fig. 14 shows another side view of the elements of fig. 13 during release of the lower catch device 100 locked at the lower holding element 101 of the panel 2. Fig. 15 shows how the lower catch device 100 has been in an open state, wherein the lower catch element 116 has moved the projection 136 of the release element 230 of the upper catch device together with it at the recess 130, so that the release of the upper catch device 200 locked at the upper holding element 201 of the panel 2 is also triggered.

In order to adjust the relative position of the panel 2 with respect to the frames 4a, 4b in the vertical direction, one or both of the respective holding

elements

101, 201 may have one of the described vertical adjustment devices 120. In this way, tolerances can be easily compensated, in particular with regard to the relative positions of the two

catch devices

100, 200 and their elements.

According to fig. 27 a-27 c, it is also possible to combine two holding

elements

101, 201 into a holding module 131 by means of a continuous, also one-piece, base 117. The two

holders

118, 218 are then attached to a continuous base 117, which may be integrated into a panel. The continuous one-piece base 117 makes it easier to assemble the combined holding

elements

101, 201 into a holding module 131.
