Description

DESCRIPTION

Coupling device for drawer with rear lock

The invention relates to a rear locking coupling device according to the preamble of claim 1.

A coupling device according to the order is known from EP 2937018 A1.

In different drawers, in particular system drawers, latches or coupling devices, with which the drawers are attached to a pull-out guide fixed to the furniture body, are a component of one or both of the side walls or frames of the drawer.

In wooden drawers, these coupling devices are often attached to a drawer base or panel, which means additional effort for the furniture maker.

In system drawers with relatively narrow side walls or frames made of metallic materials, such as steel, on the other hand, concealed pull-out guides are often used. The structure of the drawers resembles wooden drawers in this respect, i.e. the drawer with narrow side frames is arranged with a continuous base on the pull-out guides of the drawer and between the respective pull-out guide and the cabinet body In each case, there is a construction space for the side frame.

This construction space can be used for receiving a latch or a coupling device, with which the frame, and thus the drawer, are attached to the pull-out guide.

According to an embodiment variant for such a latch or for such a coupling device, as shown in FIG. 12a or 12b, a retaining spring 103' with a coupling device housing is fixed firmly. in a side frame 3' of a drawer 2'. When the drawer engages, the retaining spring 103' locks in a first retaining window 9a', which has a running rail 7' of the extraction guide 6'.

Tests have shown that a second retaining window 9b', which is provided by the running track 7' of the extraction guide 6', is not necessarily reached safely during subsequent locking. The retaining air between the retaining spring 103' and the retaining window 9a', 9b' leads to unwanted clicking noises when the drawer 2' is closed and the front panel of the drawer comes into contact with the cabinet body 1'. .

The invention aims to reduce this problem.

The invention solves this objective by means of the object of claim 1.

A coupling device for fixing and locking a drawer on a pull-out guide is achieved, the drawer having at least one base, on its sides respectively a frame, as well as a front panel, and the pull-out guide having at least a body rail and at least one running rail.

In this case, the pull-out guide is fixed with the body rail to a furniture body and a free end of the slide rail is surrounded by a hook element of the coupling device, the hook element being configured in a slider of the device coupling and hooking a retaining element retaining driver, which is movably housed in the slider, as a result of movement of the drawer on the extraction guide, in a retaining window of the rolling rail, so that the running rail is locked in the drawer due to an interaction of the hook element and the retaining element.

Finally, the slider is movably guided relative to a base element of the coupling device, the base element being fixed to the frame and the slider and base element having complementary fixing means, so that the base element and The slider can be fixed in relation to each other in different positions.

In this way, the functions of a locking of the running rail with the coupling device and thus with the drawer, as well as the function of a fine adjustment of a gap between the front panel and the housing, are functionally separated from each other. piece of furniture in the closed state of the drawer.

Due to this, the drawer is advantageously locked or fixed, so to speak, free of play in the extraction guide. In this case, the additional retaining means serve advantageously for the secure contact of the front panel with the cabinet body in the case of a drawer that is inserted completely into the cabinet body and likewise advantageously also for tolerance compensation.

According to claim 1, the fastening means are designed to be simple in construction and reliable in their ability to function as retaining means, so that the base element and the slider can be locked relative to one another in different retaining positions.

According to claim 1 the retaining means further comprise a retaining plate with retaining toothing as well as a locking spring arrangement with a tongue. The tongue can be a one-piece configured part of the locking spring arrangement, for example an end of a leaf spring, or a separate part of the spring itself, of the locking spring arrangement. Alternatively, for example, an embodiment of the locking spring arrangement is conceivable as a unit with a rotatable pawl, which can be engaged with one end in the latching toothing and is forcefully biased by a spring, in particular a helical spring. . As a result, the retaining means are advantageously simple and robust in each case. Other configurations are conceivable. There are different possibilities for the realization, thus also mixed forms from a force-fit fixing and a positive connection in different positions.

In another preferred embodiment of the invention, the base element has a parallelepiped-shaped base geometry. As a result, the base element is advantageously robust and compact, so that it can safely permanently accommodate other components as well as operating forces.

According to another embodiment, it can be advantageously provided that by means of a cam, in particular as part of a spring arrangement, such a force is applied to the retaining element that the retaining driver passes through the retaining window, in particular due to the spring force.

In another preferred embodiment of the invention, the base element has a perforation with an essentially rectangular cross-section, the perforation having one or more recesses. In this way, a component can be mounted in a simple and thus advantageous manner on the base element without additional fastening means.

In a further preferred embodiment of the invention, the at least one spring arrangement is easily hooked into the one or more recesses. The spring arrangement can be made in one or more parts in different ways. A trapezoidal spring is mentioned by way of example as a possibility for the practical embodiment, in which case a form-fitting connection can thus exist between the base element and the spring, in particular the trapezoidal spring.

In a further preferred embodiment of the invention, the base element has a cutout, which is designed in such a way that the locking spring arrangement can be connected with its free end on the base element side via the cutout. positive with the base element. As a result, the locking spring arrangement can be mounted in a simple manner, and thus advantageously without additional fastening means, on the base element.

In a further preferred embodiment of the invention, a release button is provided, the release button being arranged movably on the base element, in particular being movably guided or rotatably mounted.

In a further preferred embodiment of the invention, a housing plate is pivotally attached to the base element, so that the recesses as well as the recesses and the perforation are closed. As a result, the cam, in particular as part of the spring arrangement, the locking spring arrangement, as well as the release button, are secured in a simple and advantageous manner against falling of the base element.

In another preferred embodiment of the invention, the retaining element has a first tongue and a second tongue, the second tongue resting on a slider. As a result, by moving the slider relative to the base element, the latching element is released from the latching window in a simple and thus advantageous manner. This results in simple and thus advantageous handling of a release function of the coupling device.

In the case of another preferred embodiment of the invention, the first latch of the retaining element can be displaceable on a surface of the spring arrangement, in particular configured as a trapezoidal spring, which is arranged parallel to the free end of the latch. spring arrangement. As a result, the spring arrangement applies a permanent actuating force to the retaining element, so that the retaining driver passes through the retaining window. As a result, an advantageously secure locking of the coupling element is ensured.

In another preferred embodiment of the invention, the fastening driver has a bevel on its side facing the front panel. As a result, it is ensured in a simple and advantageous way that tolerances are compensated and that the locking of the coupling element is free of play.

The invention also creates a drawer, which has at least one base, on its sides respectively a frame, as well as on its front side a front panel, the drawer presenting at least one extraction guide, in which it is fixed with a device coupling according to one of the claims that refers to it. Furthermore, the invention provides a piece of furniture with a furniture body, which has at least one such drawer. Further advantageous developments of the invention are apparent from the other subclaims.

In FIG. 1, a cut-out of a wall or a cabinet panel of a cabinet body 1 with a drawer 2 is shown. Only one side wall of the cabinet body 1 is shown here. The drawer 2 has two frames 3, of which only one frame 3 is shown here. The frames 3 are in this case designed as so-called "narrow" frames 3, which have a relatively small width, which it can be, for example, below 15 mm. They can be made of a metallic material, such as sheet steel. However, they can also be made of another material, such as wood, or a replacement material for wood or a plastic material.

The drawer 2 has a base 4, which is attached to the frames 3. The drawer 2 also has a front panel 5. The drawer 2 can also have a rear wall, which is not shown here. The base 4 of the drawer 2 is arranged in this case separated from the lower end of the corresponding frame 3 in the direction of the upper end of the corresponding frame 3. The base 4 rests on two extraction guides 6, respectively, showing in Figure 1a only one of them. the two extraction guides 6.

The pull-out guide 6 is designed in each case as a telescopic construction, in which case only one running rail 7 of the pull-out guide 6 is shown. The pull-out guide 6 can also be designed according to another design principle. The extraction guides 6 are arranged respectively in a construction space between the base 4 and the lower end of the frames 3 and are respectively in contact with the frame 3. The extraction guides 6 are fixed to the furniture body 1, more precisely to the side wall of the furniture body 1, a curved body rail of the corresponding extraction guide 6 surrounding the lower end of the respective frame 3 (see Figure 12a for this).

The drawer 2 furthermore has a coupling device 100, with which the drawer 2 can be fixed or locked in the pull-out guide 6. The coupling device 100 is arranged in a cutout 8 of the frame 3, so that the coupling device 100 fills a construction gap in the frame 3 or between a wall of the frame 3 and the running track 7 of the pull-out guide 6 and is in contact with the running track 7 of the pull-out guide 6.

In Figure 1a a state of the drawer 2 is represented before a displacement on the extraction guides 6, while in Figure 1b a state is represented, in which the drawer 2 is fixed and locked through the coupling device 100 respectively to the extraction guide 6.

Figure 2a shows the arrangement of Figure 1a enlarged, with the furniture body 1 having been omitted or not being shown. Figure 2a shows the coupling device 100. The coupling device 100 has a compact geometry, in this case essentially parallelepiped type. A hook element 101 can be clearly seen, as well as a fastening driver 102, which is configured by a retaining element 103 at its free end. The hook element 101 accordingly has a hook. Figure 2a also shows the running rail 7 of the extraction guide 6. The running rail 7 in this case has a U-shaped cross-section. A rib of the running rail 7 has a window in its edge area. retention 9.

In Figure 2b the arrangement of Figure 1b is shown somewhat enlarged, with the furniture body 1 also being omitted. hook of the hook element 101 surrounds the edge area of the rib of the running rail 7 and the end of the rib is in contact on the base of the hook mouth of the hook. The retaining driver 102 of the retaining element 102 engages in the retaining window 9 of the rib. Due to this the drawer 2 is advantageously locked or fixed so to speak without play on the extraction guide 6. The setting of the locking play will be described in greater detail below.

In FIG. 3, the coupling device 100 and its individual parts are shown in a clearly recognizable manner. The coupling device 100 has a base element 104. The base element 104 has a parallelepiped base geometry and serves to receive, fasten and guide other individual parts of the coupling device 100.

The base element 104 has a hole 105 with an essentially rectangular cross section. The perforation 105 additionally has two recesses 106a, 106b. In the recesses 106a, 106b a spring arrangement, embodied here as a trapezoidal spring 107, is hooked with its two free ends. This results in a form-fitting connection between the base element 104 and the trapezoidal spring 107. The trapezoidal spring 107 is made of a flat material as a bending part.

The base element 104 additionally has a cutout 108, which is designed in such a way that the locking spring arrangement 109 can be connected positively with a free end of the base element via the cutout 108. 104. In the installed state of the locking spring arrangement 109, a tongue 110 engages in the base element 104, which functions as a kind of locking pawl in the installed state of the coupling device 100, of the locking spring arrangement 109, in the clearance of the recess 108. The locking spring arrangement 109 is made of flat material as a bending part.

A release button 112 is engaged in a further recess 111 of the base element 104. The release button 112 is movably guided in the recess 111 in this exemplary embodiment. In the assembled state of the coupling device 100, the release button 112 serves to unlock the locking spring arrangement 109 in the event of the coupling device 100 being blocked. In this case, the release button 112 is activated manually, i.e. it is moved in the direction of the coupling device 100. In this case, the free base element end of the release button 112 thus pushes against the tongue 110, that the tongue 110 protrudes from a retaining toothing 113, which has a retaining plate (see also FIGS. 9b, 10b for this).

A housing plate 115 is movably attached to the base element 104, preferably pivotally. The fastening is configured with a connection, in this case with a form-fitting connection, for example a riveted connection. The fixing can also be designed in another way. The housing plate 115 is pivotally attached to the base element 104 such that the recesses 108, 111 as well as the recesses 106a, 106b and the hole 105 are closed, so that the trapezoidal spring 107, the arrangement The locking spring 109 as well as the release button 112 are secured against falling out of the base element 104. The housing plate 115 has a tongue 116. The tongue 116 is produced, for example, by a chamfering process. , and has a threaded bore 107. Through the tongue 116, the housing plate 115 has an L-shaped cross-sectional geometry at least in sections. The tongue 116 engages in the assembled state of the housing plate 115 on the base element 104 in a cavity 118.

The base element 104 has a through hole 119 in the region of the cavity 118. In the assembled state of the cover plate 115, a screw 120 passes through the through hole 119 and the threaded hole 117. With the screw 120 you can The inclination of the base element 104 relative to the housing plate 115 can thus be adjusted via the threaded bore 117. In the assembled state of the coupling device 100, the housing plate 115 is in contact with the respective frame. 3 of drawer 2 and fixed to it.

The coupling device 100 furthermore has a slider 121. The slider 121 has guide surfaces 122 of a sliding guide, through which it is displaceably guided by the base element 104. The base element 104 has correspondingly thereby geometrically corresponding guide surfaces 103 . The guide surfaces 122, 123 or the sliding guide are/are configured in such a way that in the mounted state of the slider 121, a kind of flat guide results in the base element 104. The type of the sliding guide can also be geometrically configured in another way. The slider 121 has, at least in sections, a U-shaped cross-sectional geometry, so that the slider 121 has a shell-like configuration. The slider 121 additionally has the hook element 101 at its free end. On an inner side of an arm of the C-shaped cross-section of the slider 121, the retaining plate 114 is connected here via a riveted connection. positive connection with the slider 121. In this case, the retaining toothing 113 is directed towards the inner side of the U-shaped cross-section of the slider 121.

Furthermore, the retaining element 103 is mounted in the slider 121 in a movable, preferably pivotable manner. In this connection, the retaining element 101 is arranged on the shell-like inner side of the C-shaped cross section of the slider 121. The retaining driver 102 of the retaining element 103 is directed in the same direction as the hook element. 101 of the slider 121. The slider 121 is configured in such a way that the retaining driver 102 can be swiveled out of the C-shaped cross section. For this, the slider 115 has a cutout 124.

In addition, the retaining element 103 has a first tongue 125 and a second tongue 126. The tongues 125, 126 are each produced, for example, by a chamfering process and configured in such a way that through the tongues 125 , 126 conceptually results in a U-shaped cross-section, at least in sections, of the retention element 103.

In Figure 4a the drawer 2 is represented in a partial top view. In a shown here starting state of a locking process of the drawer on the pull-out guides 6 (not shown here) together with the coupling device 100, the front panel 5 of the furniture body 1 is separated with the gap A.

In FIG. 4b, the drawer 2 is shown in section through the coupling device 100. The coupling device 100 is shown in the assembled state. It can be clearly seen that the coupling device 100 is arranged in the cutout of the frame 3 of the drawer 2.

The retaining element 103 can also be clearly seen, here in the unlocked state, which is movably mounted, preferably pivotally, in the slider 121. The second tongue 126 of the retaining element 103 rests on a slider 127. It can be The trapezoidal spring 107 can also be clearly seen, which engages with its two free ends in the recesses 106a, 106b.

The running rail 7 of the extraction guide 6 is in contact with one of the ribs of the U-shaped cross-section of the slider 121. You can also clearly see the retaining window 9 in the running rail 7. Also the hook element 101, which forms the slider 121. The hook or hook mouth of the hook element 101 is configured in such a way that it can surround a running rail rib 7 on three sides. The retaining plate 104 with the retaining toothing 113 is also shown in a clearly recognizable manner. The locking spring arrangement 109, which rests with its free end pointing towards the central body in the recess 111 of the base element 104. The tongue 110 of the locking spring arrangement 109 engages in this starting position of the locking process in a tooth gap of the retaining tooth system 113, which is arranged further away in the direction of the front panel 5. The release button 112 is accordingly not actuated, however, its free end facing the locking spring arrangement 109 is in contact with the locking spring arrangement 109.

Correspondingly, the slider 121 and the base element 104 have complementary retaining means, i.e. the locking spring arrangement 109 or the tongue 110, as well as the retaining plate 114 or the retaining toothing 113. so that the base element 104 and the slider 121 can be locked relative to each other in different retention positions.

The retaining means 109, 110, 113, 114 serve advantageously for the safe contact of the front panel 105 with the cabinet body 1 in the case of drawer 2 completely inserted in the cabinet body 1, as well as advantageously also for tolerance compensation.

In Figure 5a the drawer 2 is represented in a partial top view. In the state shown here of the locking process of the drawer 2 on the extraction guides 6 (not shown here) through the coupling device 100, the front panel 5 is separated from the furniture body 1 with a gap B, the gap being B smaller than gap A in Figure 4a or 4b. In other words, drawer 2 moved further on extraction guide 6.

Compared to Figure 4b the hook of the hook element 105 surrounds in Figure 5b the front panel side free end of the running rail 7 of the extraction guide 6, so that the front panel side free end enters in contact with the base of the hook mouth, which forms the hook element 101.

As a result, the extraction guide 6 is surrounded on three sides by the hook element 101 of the slider 121 on its running rail 7. This advantageously results in a defined gap between the base of the hook mouth of the hook element 101 with respect to the retaining window 9 of the running rail 7.

Also in Figure 6a the drawer 2 is shown in a partial top view. In the state shown here of the locking process of the drawer 2 on the extraction guides 6 (not shown here) through the coupling device 100, also called rear locking, the front panel 5 is separated from the furniture body 1 with a gap C, gap C being smaller than gap B of Figure 5a or 5b. This means for its part that the drawer 2 has moved further in the direction of the furniture body 1. This is possible even though the running track 7 of the extraction guide 6 is already in contact with the base of the hook mouth of the element. hook 101, since the base element 104 (not shown here) can move relative to the slider 121.

Compared to Figure 5b, by moving the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 relative to the slider 121, the retaining element 103 has likewise been displaced relative to the guide. extraction 6.

As a result, the first tongue 125 of the retaining element 103 was displaced on a surface 128 of the trapezoidal spring 107, which is arranged parallel to the free ends of the trapezoidal spring 107. As a result, the retaining element 103 has led to It performs a counterclockwise pivoting movement about its pivot point P, so that the clamping driver 102 of the retaining element 103 now passes through the retaining window 109. As a result, the extraction guide 6 is locked against through the coupling device 100 with drawer 2.

Via the trapezoidal spring 107, a continuously acting force is applied to the retaining element 103, which ensures that the retaining driver 102 reliably passes through the retaining window 9.

On its side facing the front panel, the retaining driver 102 has a chamfer 129 (see also FIG. 3). Dimensional tolerances of the hook element 101 can be compensated for by the chamfer, so that the chamfer 129 advantageously ensures, so to speak, a fixed, play-free locking.

Furthermore, the locking spring arrangement 109 has also been moved relative to the slider 121 and thus relative to the retaining plate 114. As a result, the tongue 110 of the locking spring arrangement 109 now engages in a tooth gap of the retaining toothing 113, which is arranged in direction front panel 5 behind the tooth hole, which is furthest in the direction of drawer extraction 2.

In the state shown in Figure 7a of the drawer 2 on the extraction guides 6 (not shown here) through the coupling device 100, the front panel 5 of the drawer 2 is separated from the furniture body 1 with a gap D, being gap D again smaller than gap C of Figure 6a or 6b. This means for its part that the drawer 2 has moved further in the direction of the cabinet body 1, so that a gap between the front panel 5 and the cabinet body 1 continued to be minimized. This is possible despite the fact that the running rail 7 of the extraction guide 6 is already in contact with the base of the hook mouth of the hook element 101, since the base element 104 (not shown here) can be displaced relative to slider 121.

This is depicted in a recognizable manner in FIG. 7b. Essentially differences or additions to Figure 6b are described below. Compared to FIG. 6b, due to the movement of the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 in relation to the slider 121, the locking spring arrangement 109 has also been displaced in relation to the slider. 121 and thus in relation to retaining plate 114.

As a result, the tongue 110 of the locking spring arrangement 109 now engages in a tooth gap of the retaining tooth system 113, which is located between the tooth gap, which is arranged furthest in the extraction direction, and a tooth gap. tooth gap, which is arranged furthest in the posterior wall direction (not shown here).

In Figure 8a the drawer 2 is shown in a partial top view. In the state shown here of the locking process of the drawer 2 on the extraction guides 6 (not shown here) through the coupling device 100, the front panel 5 is in contact with the furniture body 1. This is possible despite that the running rail 7 of the extraction guide 6 is already in contact with the base of the hook mouth of the hook element 101, since the base element 104 (not shown here) can move relative to the slider 121. This is shown in a way that can be clearly seen in Figure 8b. Compared to Figure 7b, by moving the base element 104 in the direction of the rear wall (not shown here) of the drawer 2 relative to the slider 121, the locking spring arrangement 109 has also been displaced relative to the slider 121 and thus relative to retaining plate 114.

As a result, the tongue 110 of the locking spring arrangement 109 now engages in the tooth gap of the retaining tooth system 113, which is arranged further away in the rear wall direction (not shown here). Due to the retaining toothing 113 with several tooth gaps, it is possible, depending on the tolerance position, that this tooth gap is not reached, even though the front panel 5 has come into contact with the furniture body 1. In this case, In this sense, the retaining toothing 113 serves not only advantageously for the secure contact of the front panel with the cabinet body 1 in the case of the drawer 2 inserted completely into the cabinet body 1, but also advantageously also for tolerance compensation.

In Figure 9a the drawer 2 is shown in a partial top view. In the state shown here at the beginning of the unlocking process of the drawer 2 from the extraction guides 6 (not shown here) through the coupling device 100, the front panel 5 is in contact with the furniture body 1.

This is depicted in Figure 9b. Compared to Figure 8b, in Figure 9b the unlocking button 112 is actuated, so that the tongue 110 of the locking spring arrangement 109 has moved away from the detent toothing 113. The actuation of the unlocking button 112 is possible manually, since the geometry of the respective cutout 8 of the respective frame 3 has such dimensions that such a manual or manual actuation of the release button 112 is possible. As a result, the front panel 5 and thus the Drawer 2 in total of furniture body 1 in the extraction direction, so that a gap with a gap E can be formed again.

This is depicted in Figure 10a and Figure 10b. Due to the actuated release button 112, the tongue 110 of the locking spring arrangement 109 is no longer engaged with the latching toothing 113, so that by means of the relative displacement capability of the slider 121 with respect to the base element 104 , the front panel and thus the drawer 2 can be moved further away from the furniture body 1 in the extraction direction.

Figure 10b shows a state of the unlocking process, in which case the first tab 125 of the retaining element 103 has left the surface 128 of the trapezoidal spring 107 and the second tab 126 of the retaining element 103 moves on the slider 127 In this sense, the retaining element 103 has carried out a pivoting movement in a clockwise direction about its pivot point P. However, the retaining driver 102 continues to engage in the retaining window 9.

Via the slider 127, in the event of further movement of the drawer 2 in the extraction direction, i.e. away from the furniture body 1, the retaining element 103 is pivoted further in a clockwise direction about its pivot point P. As a result, the retaining driver 102 of the retaining element 103 is moved out of the retaining window 9, as is clearly shown in FIG. 11b.

In this way, the starting state according to Figure 4a or 4b is reached again, so that the drawer 2 can be removed from the pull-out guide 6.
