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 which can be arranged on the panel side and has at least two catch devices arranged on the frame side.

Background

DE 94 21 872 U1 describes a fastening device for fastening a front panel of a drawer to a drawer frame. The fastening device has, in addition to the retaining spring, a locking device which acts 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. very large stresses due to shaking movements or the like.

EP 2747599A discloses the use of two or more catch devices arranged one above the other in a relatively high drawer. Thus, it is necessary to lock and release the two catch means respectively 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 devices, which is on the one hand generally relatively expensive and on the other hand has the disadvantage that the actuation force during unlocking is relatively high, since only a single actuation has to be used to move the catch devices from the locked position to the unlocked position against the mutually applied spring forces of the two securing devices.

Disclosure of Invention

The object of the present 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 present invention solves this problem by products and methods according to some embodiments.

Advantageous embodiments of the invention may be found in some embodiments.

According to a feature of some embodiments, for locking purposes, the catch means are mechanically coupled to each other in a functionally efficient manner, so that the catch means can be locked together on the holding elements-either by one application or by a single actuation. In contrast, for unlocking, the two catch devices are not coupled to each other in a mechanically functionally effective manner, i.e. they are mechanically separated, so that the unlocking is or has to be performed by separate actuation of the two catch devices. In other words, the two catch devices have a mechanically effective connection when locked and they are not mechanically effective connected when unlocked, but have to be actuated-released separately.

This has the advantage that the force required for the release is much smaller than in a design in which the two catch means are moved together into the release position by only one single actuation, since in the case of a design in which 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 carried out separately against the action of only one of the spring means at different times. Although the release takes a longer time for each frame-typically 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.

Furthermore, the features of some embodiments are advantageous in that from a design point of view only a kinematic coupling for locking has to be implemented, not a kinematic coupling for release that would make the assembly of the device consisting of two catch devices significantly more complex.

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 due to a partial displacement of the rotation axis 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 the construction, the release element can then advantageously be arranged in a simple manner such that it is rigidly coupled to the catch element of one catch device both during unlocking and during locking, and such that it 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 partial displacement of the rotation axis of the catch element, it is advantageous if a rotational movement or pivoting of the respective catch element about its rotation axis is superimposed or preceded or followed by a movement of the rotation axis which displaces the rotation axis locally, preferably linearly. Such defined displacement of the rotational axis position may be achieved in particular by displacing the central axis of the shaft section or bolt or the like, with or on which the catch element of the catch device is pivotally mounted. In this case, the position is shifted to a catch position, which is selected such that an additional locking effect is produced as a function of the shift of the rotation axis.

It may be advantageously 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 it is locked to the catch device.

Furthermore, in order to achieve a well-functioning interlock, it may be provided that the displacement of the respective rotation axes is implemented such that, in the catch position, it is located in the Y-direction perpendicular to the main extension direction of the frame or in the Y-direction close to the central axis of the holding bolt of the holding element. It may be realized such that in the locked or interlocked state of the catch arrangement the momentary rotation axis of the catch element may preferably lie just below or above the effective plane or on the effective plane of the holding element, in particular of the holding bolt of the holding element on the panel. The effective plane is defined here by a plane defined between the X-axis and the Z-axis, which runs parallel to the bottom of the frame. This means that by means of the opening movement of the drawer, with the 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 it is advantageously practically impossible to overcome the locking mechanism by means of the opening movement of the drawer alone. Thus, no additional, for example rigid locking latches are required to hold the catch element in the holding position, or no clamping action is required to be achieved for holding the holding element.

In a preferred embodiment variant of the invention, the drive geometry for the tool is integrated into the catch element of a catch device. The drive geometry interacts with the tool in a simple design and in a production-related manner and is therefore advantageously used for 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 the release element assigned to the catch device.

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

It may advantageously be provided that the displacement of the rotation axis of each catch element is defined by a mechanical control device which relates the displacement of the rotation axis to the pivoting 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. If the mechanical control is formed by a corresponding transmission, it is simple and safe in terms of design. Thus, according to an advantageous design, the transmission means may comprise transmission means of the catch means and corresponding transmission means of the base element.

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

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

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

A housing is simply and advantageously formed in which the catch element is safely accommodated. 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 the wall surface of the frame. However, this is not absolutely necessary, but is merely a constructional choice.

In a further preferred embodiment variant of the invention, the holding element comprises a holding portion and a holding bolt, which holding portion is attached to the base portion and can have a U-shaped cross-sectional geometry, wherein the U is then dimensioned such that the clear width of the U is greater than the width B of the housing. 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 adjustment device. This ensures, in a simple and advantageous design, an adjustment of the relative position of the panel in the vertical and/or horizontal direction and/or in the oblique 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 element. Thanks to the pivot joint, the spring means always advantageously act on the catch element without bending moment.

In a further preferred embodiment variant of the invention, the two holding elements can be joined to form 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 results in an advantageously simplified assembly of the holding elements, which are thus combined to form the holding module. Preferably, the two retaining bolts are vertically spaced above and below each other.

According to the method according to some embodiments, the panel is fixed by a single application movement, wherein the two catch means are released time-lapse one after the other and engage with at least one holding element, in particular two holding bolts.

According to a method according to some embodiments, the catch means are detached separately for release from the at least one holding element, in particular the two holding bolts.

The method thus supports the advantageous idea that, from a design point of view, only the coupling for locking has to be achieved, without the kinematic coupling for release having to be achieved which would make the assembly of the device constituted by the two catch devices significantly more complex.

Detailed Description

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

Fig. 1 and 2 each show one half of a drawer 1 in different views. The drawer 1 has a front 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 simplicity, only one of the frames 4 is shown and described below.

A fixing device 10 for fixing the panel 2 of the drawer 1 to each frame 4 is provided-see also fig. 4 and 5-in which the fixing device 10 has at least one or two one-piece or multi-piece holding elements 101, 201 which can be arranged on the front panel side and two catch devices 100, 200 which can 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 alone or connected to each other and to the panel 2 as an overlapping stack (see fig. 27). They are preferably arranged vertically to each other on the panel or are designed to be spaced apart from each other.

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 (referred to as locked position, see fig. 5). From which they can be released (referred to as release position, see fig. 11, then 12) in order to separate the panel 2 from the respective frame 4.

The frame 4 may for example be made of a metallic 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 may 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 by screwing. It can also be engaged in a cavity in the frame 4, which is preferably aligned at right angles to the panel in the catch position.

In order to be able to actuate the respective catch device 100, 200, in particular to unlock and release it, the frames 4 may each have a cut-out 5a, 5b, which cut-out 5a, 5b may optionally be covered by a cover or overlapping cut-out (not shown), through which cut-out 5a, 5b the catch device 100, 200 inserted into the respective frame 4 is accessible from the outside and actuated.

The two catch devices 100, 200 are coupled together in a mechanically functionally effective manner to lock and reach a locked position such that they can be locked onto 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 effective manner, so that unlocking is performed by separate 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 means must first be explained.

Fig. 19 shows a fixing device 10 for fixing the panel 2 of a drawer to the frame 4, the panel 2 of the drawer having a smaller height than in fig. 1, the frame 4 having a correspondingly smaller height. The fixing device 10 has a panel-side holding element 101 and a single frame-side catch device 100. The capture device 100 has capture elements 116 pivotally mounted to respective frames.

The catch element 116 can be subjected to forces by the energy storage means, in particular the spring means 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 capture 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 which is fixed to the frame 4, for example an element which is 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 is used for arranging the energy storage device and also as a support for the energy storage device. The energy storage device is preferably designed as a spring device. The term "spring device" is therefore used hereinafter, which in the following and also in the claims includes different types of energy storage devices.

In this case, the spring means 104 comprises a compression spring. Alternatively, the spring device 104 may also have another spring of a different design. The spring device 104 also has a guide element 105. The guide element 105 is here movably mounted 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 card capturing mechanism 100 may have a housing 108, the housing 108 having a first right half-shell 107a and a second left half-shell 107b extending parallel thereto, as a further complement to or entirely as a mounting base.

Here, the half shells 107a, 107b are joined together (in this case with rivets) to form a shell 108. The half shells 107a, 107b are made of a metallic flat material, for example steel plate. Alternatively, the half-shells 107a, 107b may also be made of another material, such as aluminum or plastic, for example. A gap or a slit may be formed between the housings for accommodating the necessary functional elements of one or both of the catch devices 100 and 200 according to fig. 1 to 18.

The mounting base, here a housing 108 with a base element 102, may have at least one slotted connection 109, in which slotted connection 109 a guide cam 110 is slidably mounted. Here, the half-shells 107b, 107a each have a slotted connection 109, in which slotted connection 109 a guide cam 110 is slidably mounted. In addition, a second left half shell 107b may have a recess 111. Through this recess 111 a curved slotted hole 112 is visible, which is introduced into the first right half-shell 107a.

The two half-shells 107a, 107b each have geometrically identical, slot-like cutouts 114a, 114b. In the locked position of the catch arrangement 100, the cutouts 114a, 114b are penetrated by the holding bolts 115 (in the horizontal position) of the holding element 101 (see fig. 19). Further, in the locked position, the catch elements 116 are each engaged in the cutout 114.

Fig. 19 also shows the holding element 101 in an exemplary design. The holding element 101 has a base 117, the holding element 101 being attached to the panel 2 of the drawer 1 by the base 117. 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 the holding portion 118 is locked or after having been 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 adjusting device 120.

If two catch devices 100, 200 are arranged one above the other, two such holding elements 101, 201 may be arranged one above the other on the panel 2 or a holding element 101 with two holding bolts may be arranged on the panel 2 (fig. 27).

In fig. 20, the card capturing device 100 is shown without the left half shell 107 b. Thus, the capture element 116 is clearly visible. The catch element 116 has a transmission 121. The base element 102 also has a transmission 122. The two transmissions 121, 122 are meshed with each other and are thus operatively connected to each other. The transmissions 121, 122 are preferably involute gear teeth. Other transmission arrangements are also conceivable. The centre planes of the catch element 116, the transmission 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, if possible, all forces can be released in one plane without tilting moments being generated.

The catch element 116 has a semicircular recess 123, in which 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 means 104 is thus operatively connected to the catch element 116. Due to the pivot joint, the spring means 104 advantageously acts on the catch element 116 with as little bending moment as possible.

The catch element 116 also has a slot-like cutout 125. The borders 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 holding bolt 115 of the holding element 101 can pass through the cutout 125 in the horizontal direction with little play at any time. Hooks 127 in the catch element 116 are formed by cutouts 125.

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

The drive geometry 113 can also be seen, wherein the drive geometry 113 is embedded in the catch element in the form of a cross-shaped recess in a region. The drive geometry 113, in combination with a corresponding actuation tool (here a phillips screwdriver), serves as 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 half shell 107 a.

Thus, the slotted hole 112 serves as a free space for the screwdriver tip, so that a reliable rigid connection between the driving 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 the locking process of the catch device 100 for locking panels in different sequential steps or increments (increments).

In fig. 21, the catch device 100 is shown without the frame 4 surrounding the catch device, but with the holding element 101 in the basic position in which the catch device 100 is open.

In fig. 22, the capture device 100 is shown in the following positions: wherein the retaining bolts 115 engage in cutouts 114a,114b each formed by the two half-shells 107a, 107b and are in contact with the catch element 116. The recesses 119a, 119b of the holding portion 118 have been placed on the two half-shells 107a, 107b (here only 107a is shown), so that the holding bolt 115 engages centrally in the cutouts 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 has been partially rotated clockwise about the shaft section 126 by the movement of the holding bolt 115 on the catch element 116 and has displaced the effective line of spring force to such an extent 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 holding bolt 115 into the cutouts 114a,114 b. This movement is possible because the central axis of the holding bolt 115-at a vertical distance from the instant position of the central axis of the shaft section 126-acts on the catch element 116, whereby a torque acting in a clockwise direction is exerted on the catch element 116.

The transmission 121 of the catch element 116 has rolled down (roll off) to some extent on the transmission 122 of the base element 102. Due to the rolling movement, the shaft section 126 and thus the momentary rotational axis 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 capture device 100 is shown in a position in which the retaining bolt 115 is engaged in the cutouts 114a, 114b and in which the cutout 125 or the hook 127 of the capture element 116 is engaged 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 in comparison with fig. 22.

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

In fig. 24, the catch arrangement 100 is shown in a position in which the holding bolt 115 is engaged in the cutouts 114a, 114b and in which the cutout 125 or the hook 127 of the catch element 116 has pulled the holding bolt 115 and thus the holding element 101 further into the cutouts 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. Because of the spring force of the spring element 104 or the force stored in the compression spring, the catch element 116 has again rotated further partially clockwise about the shaft section 126, as compared to fig. 23.

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

In fig. 25, the catch device 100 is finally shown in a locked end position, in which the retaining bolt 115 is engaged in the cutouts 114a, 114b and the retaining bolt 115 is located at the bottom of the cutout 125. Thus, the panels 2 (not shown here) have already 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 been rotated further partially clockwise around the shaft section 126, as compared to fig. 8, to the possible end point.

The transmission 121 of the catch element 116 rolls off further on the transmission 122 of the base element 102. Due to the rolling movement, the shaft section 126, and thus the momentary rotation axis of the catch element 116, is slightly moved further vertically downwards than in fig. 9 to the lower end point of the slotted connection 109 by 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 central axis of the shaft section thus now lies just below the effective plane a and/or on the effective plane of the holding bolt 115 in the cutout 114a, 114 b. This means that by means of the opening movement of the drawer 1, with the concomitant force exerted on the panel 2, only little or no torque can be exerted on the catch element 116, so that it is advantageously practically impossible to overcome the locking mechanism by means of the opening movement of the drawer.

Furthermore, the catch element 116 has already been abutted 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 rotation 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 link 109 and is supported by the rolling of the transmission 121 of the catch element 116 on the transmission 122 of the base element 102.

The catch device 100 can only be unlocked by a rotational movement of the catch element 116 against a rotational locking direction, which is activated 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 catch 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 pivotally mounted, and two guide cams 110 which are integrally formed with the shaft section 126.

In the case of a high drawer 1 with a high panel 2 and a high frame 4, in the illustrated embodiment, this design of fig. 19 to 25 is basically used on both catch devices 100, 200.

The corresponding elements of the two catch devices 100, 200 differ by the first digit of the reference number, which starts with a "1" for the lower catch device 100 and a "2" for the upper catch device 200. In the case of elements used in both capture devices 100, 200, they are labeled "1".

This means that a housing 108 with two half-shells 107a, 107b can be used for both catch devices 100 and 200 (see fig. 18 and fig. 4 and 5). Base elements 102, 202 may be provided for each of the capture devices 100, 200, respectively.

The preferred construction of the upper and lower card grasping devices 200, 100 is described below. The function of the upper capture device 200 may also be interchanged with the function of the lower capture device 100. For this purpose, only a mirror-symmetrical design of the catch means has to be achieved.

Here, the two catch devices 100, 200 are further designed and arranged such that the design of the lower catch device 100 corresponds in principle to the arrangement of fig. 19 to 25, so that during locking the catch element 116 rotates such that the cutout 125 engages on the holding bolt 115 from top to bottom; while the construction of the upper catch arrangement 200 is designed such that during a bottom-up locking, the cutout 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 implement. The arrangement shown can also be used on a "head" rotated 180 ° to lock the panel. Hereinafter, the function of the device consisting of the two card capturing devices 100, 200 is described in more detail with reference to fig. 5 to 18.

Fig. 5 shows the two catch devices 100, 200, each in a final locked position, such that the panel 2 is firmly attached to the respective frame 4.

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

This is because the current rotation axis 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 holding bolt 115, 215 in the cutout 114a, 114 b. Thus, by the opening movement of the drawer 1, with a force exerted on the panel 2, only little or no torque is exerted on the respective catch element 116, 216, so that it is advantageously practically impossible to overcome the locking mechanism by the opening movement of the drawer 1 only.

The two catch devices 100, 200 of the fastening device 10 differ in terms of the arrangement of the catch elements 116, 216 on the one hand and in terms of other constructional details on the other hand.

Here, the design of the lower catch device 100 corresponds almost entirely to the design of fig. 19 to 25. However, in the mounted position relative to the bottom panel 6 of the drawer 1, an edge recess 130 is provided at the upper edge of the lower catch element 116. Here, as an example, it has a trapezoid shape.

In one aspect, the upper capture device 200 has a functional orientation opposite to that of the lower capture device described above.

The release member 230 (a "release lever") is then assigned to the catch member 216 of one catch device 200 (here the upper catch device).

The release member 230 is located just below the upper capture member 216 between the lower capture member 116 and the upper capture member 216. The release element 230 has a drive geometry or actuation profile 231 for applying the actuation tool. The actuation 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 arcuate 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 actuation tool such that the release element 230 can move together with the actuation tool in the slotted connection 232.

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

Fig. 5, 6 and 7 show how the release element 230 can be moved from right to left in the slotted connection 232 by means of an actuating tool (not shown here), whereby the catch element 216 is moved downwards at its transmission 121 at the corresponding transmission 122 of the base element 212 and finally pivoted clockwise until the slot 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 capture device 200 has been moved to the release position (see FIG. 8).

The lower catch element 116 is then moved in a similar manner by the actuation means at its drive profile 113 from the locking position (fig. 8), wherein further movement and actuation into the unlocking position takes place separately. Here, the lower catch element 116 pivots counterclockwise and moves upward at the transmission 121 until the cutout 125 of the lower catch element 116 finally releases the retaining bolt 116 of the lower catch element 116 (fig. 8 to 11). This also moves the lower capture device 100 and the upper capture device 200 together to a 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 separate actuation from the locking position to the release position.

The two catch devices 100, 200 are thus designed in a preferred and advantageous, but not necessarily so, manner without being mechanically and functionally effectively coupled to one another, so that the unlocking is effected by a separate actuation of the two catch devices.

On the one hand, this has the advantage that the force required for the release is much smaller than in a design in which the two catch devices 100, 200 are moved together to 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 to the release position by only one single actuation, the two catch devices would have to be released by only one single actuation movement against the action of the two spring devices 104, 204. However, in the case of the actuation of the two catch devices 100 and 200 respectively, the release is carried out 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 from a design point of view that it is not necessary to implement a corresponding kinematic coupling which would make the assembly of the device constituted by the two catch devices more complex.

The release element 200 may be arranged in particular in a limited movement pivotable on the upper catch element 216. This is achieved here by: one of the release elements 230, here the upper end, engages in a jigsaw-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 pivot 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 element 216 and the release element 200, by means of which spring the lower end of the release element is pressed away from the upper end of the catch element 216.

In the release position of fig. 9, after removal of the actuation tool, the release element 130 essentially pivots downwards due to the action of the spring 235. In the release position of fig. 12, the lower projection 236 of the release element 130 protrudes into the edge recess 130 of the lower catch element 116. In this way, a rigid connection is achieved between the release element 230 of the upper capture device 200 and the capture element 116 of the lower capture 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 holding element by a single actuation, here a single applied movement of the panel 2.

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

This is possible because the upper catch element 216 is designed such that the upper holding 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 the upper catch element is also at a distance from the upper holding bolt 215 in this position. Thus, 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 grab device at this insertion depth, the lower grab device 100 is caused to be triggered (fig. 14). Furthermore, a respective holding lug 237 is integrally formed on at least one of the half-shells 107a, 107b, which projects into the cutout (114, 214). The holding lugs 237 can be used to pre-position the holding bolts 115, 215 and thus the panel 2 on the frame 4, so that, for example, the panel 2 can be prevented from falling off 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 retaining element 101 of the panel 2. Fig. 15 shows how the lower catch arrangement 100 has been in an open state, in which the lower catch element 116 has moved the protrusion 136 of the release element 230 of the upper catch arrangement together with it at the recess 130, so that the release of the upper catch arrangement 200 locked at the upper retaining 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 respect to the relative positions of the two catch devices 100, 200 and their elements.

According to fig. 27 a-27 c, the two holding elements 101, 201 can also be combined into a holding module 131 by means of a continuous, also integral, base 117. The two holders 118, 218 are then attached to a continuous base 117, which may be integrated into the panel. The continuous integral base 117 makes it easier to assemble the combined holding elements 101, 201 into the holding module 131.
