EP1690473A2 - Touch-latch system for furniture with relatively moving furniture parts to each other, in particular furniture drawers, furniture doors or furniture flaps - Google Patents

Abstract

The drawer mounting system comprises a carcass rail (7) and a drawer rail (8) and optionally an intermediate connecting rail (9). The gap (3) between the front of the drawer and its front panel (4) can be adjusting using a knurled screw (10) in a mounting (18) attached to the drawer rail.

Description

The invention relates to a touch-latch system for furniture with mutually relatively movable furniture parts, in particular furniture drawer, furniture door, or furniture flap, according to the preamble of claim 1.

Such touch-latch systems are u.a. used on drawers or doors without handle on the front panel. Such touch-latch systems are known per se from the prior art, e.g. a Touch-Latch-System with the Kuli-Principle (rotary motion), or a Touch-Latch-System with a backdrop (2D-Herzkurve, 3D-Kurve).

Such devices are used to allow the opening and closing of drawers, doors, flaps and any other movable furniture parts that, for example, have no handle for aesthetic reasons. Opening and closing such movable furniture parts, for example, by lateral actuation of the front panel or other accessible part, is impractical or not possible, since it can not be operated and does not allow safe operation.

There are fittings for opening drawers are known, which are actuated by the drawer is pressed by a predetermined distance and then extended by a spring mechanism. This function is achieved in a known manner via so-called touch-latch fittings.

DE 198 21014 A1 discloses a device for opening a closure element, in particular a drawer, door, or flap of a piece of furniture, wherein a drive unit for opening the drawer, door, or flap is provided and a triggering element with in particular an el Front panel of the drawer, door, or flap is provided for operating the drive unit.

DE 100 08 350 A1 discloses a device for opening a furniture cover, in particular a drawer, door, or flap of a Piece of furniture, wherein a combination of a touch-latch fitting is provided with a damper and the touch-latch fitting is attached to a separate lower shell of the furniture cover.

EP 1 183 963 A1 discloses an adapter and a drawer with this adapter, which has at least two functional elements by means of which the opening and / or closing operation of the drawer can be influenced. As functional elements damping, locking and unlocking, motors and springs for opening and closing the drawer and touch-latch fittings with labyrinth and drive spring are disclosed. The touch-latch fittings are connected to the drawer frame at the rear of the drawer below the bottom of the drawer, which destroys storage space in the drawer.

DE 295 07 917 U1 and EP-743032 B1 disclose an underfloor rail system for drawers with a touch-latch system with a drawer in the closed position locking spring-loaded locking element, which is arranged below the guide rail system on the underside of the fixed carcass rail. The spring-loaded locking element is a latch which can be moved by means of a arranged on the extendable drawer rail driver. The latch is slidable in a flat guide body with a guideway with turning loop in the extension direction of the drawer. Disadvantage is that the arrangement of the touch-latch system below the guide rail system at the bottom of the fixed cabinet rail storage space is lost for the underlying drawer.

EP 1 314 842 A1 discloses a device for opening and closing a movable furniture part, in particular a drawer, door or flap, which corresponds to a touch-latch system. The device comprises two triggering and drive units, each having a triggerable by external force trigger element and a trigger element coupled to the drive element for moving the furniture part, and at least one locking element for locking the furniture part in the closed position and release of the furniture part in dependence of an outer Force on at least one trigger element, wherein the two tripping / drive units synchronously and substantially free of play by way and force-transmitting means are coupled together. The entire device is located in the front of the drawer and is mounted on corpus firm stops on the drawer bottom. The advantage is that you can press anywhere on the front panel to open the drawer, as a large trigger area is present. Disadvantage is the complex and cost-intensive construction, and also the large trigger area due to an unintentional triggering. If two independent per se known touch-latch fittings are provided, sometimes only one fitting is triggered, the other not. Another disadvantage is that the device takes a relatively large amount of space below and next to the drawer to complete and therefore storage space for the drawer is lost in itself.

DE 101 18 394 A1 discloses a touch-latch system with rotary movement and locking pin for doors, flaps and extracts of furniture. The exact arrangement of the touch-latch system on the furniture is not disclosed.

DE 100 60 655 A1 discloses a touch-latch system with rotary motion for doors, flaps and pull-outs of furniture. The exact arrangement of the touch-latch system on the furniture is not disclosed.

EP 0 131 909 A2 discloses a touch-latch system for ashtrays in the car with the coolie principle (rotary motion and 8-slot system). The touch-latch system is located in the rear of the car ashtray between the rear wall of the hinged part and the underside of the ashes for the ashtray.

GB 2 117 472 A discloses a cylindrical touch-latch system with 3D curve as a doorknob for a building door, but not for a piece of furniture.

Object of the present invention is to provide an initially described generic touch-latch system, which allows a simple and inexpensive adjustment of the front panel.

To achieve the objects, the present invention is characterized by the features of claim 1.

It is essential that the touch-latch fitting is designed to be adjustable in length.

The advantage is that a simple and cost-effective adjustment of the front panel is made possible by the length adjustability of the touch-latch fitting.

Preferably, when the entire touch-latch system or at least the touch-latch fitting of the touch-latch system is fully or almost completely integrated into existing components of the furniture, namely within the rail system (especially in the drawer rail, in particular at their a free end in the front area), or within the drawer (decor) in particular over the rail system, in particular in the rear wall area, or within a specially created recess in the material of the furniture body in particular in the rear wall area. It can also be provided that the touch-latch fitting is integrated in the door.

The advantage is that no additional space for the touch-latch fitting is required by integrating the touch-latch fitting into existing components of the furniture, so that the storage space for items to be stored in the furniture body, especially the drawer, in the desired manner can be maintained, or compared to furniture with touch-latch systems of the prior art is considerably increased.

The furniture drawer according to the invention comprises at least one touch-latch system with at least one touch-latch fitting, wherein preferably at least one pull-out in the furniture drawer is provided which includes at least one cabinet rail and a drawer rail and possibly a center rail.

In a first embodiment of the invention, the touch-latch fitting includes at least one preferably cylindrical housing and a sliding and / or rotating part, wherein the touch-latch fitting via a first part (housing or sliding and / or rotating part) directly or indirectly with one of the rails (cabinet rail, middle rail, drawer rail) is connected and on her other Part (sliding or rotating part or housing) temporarily during the opening and closing directly or indirectly with another rail (carcass rail, center rail, drawer rail) is in contact or can be coupled.

The touch-latch fitting is integrated in the existing components of the drawer and is therefore invisible or almost invisible in the retracted and / or extended state of the drawer / door / flap arranged in the furniture. No part of the touch-latch system comes out of the body during the movement of the drawer or stands out during the retracted or extended drawer / door / flap, so that there is no risk of injury to the user and no optical interference, but a harmonious design ,

There are also no complex attachments for the touch-latch system according to the invention necessary, such as an adapter, an additional strip or a stop, according to the prior art, which would have to be positioned accurately.

Also, no holes are necessary to plug the touch-latch system into the drawer.

The invention is expressly not limited to a drawer, but the attachment on the guide may be arbitrary, such. a drawer, a wire basket, a plate, etc. Also, the touch-latch system according to the invention, of course, in connection with furniture doors and furniture flaps used, so that no restriction on rail systems should be made.

In particular, it is provided that the housing of the touch-latch fitting is indirectly or directly connected to the drawer rail, preferably in the front region of the drawer rail, and the sliding and / or rotary member directly or indirectly on the cabinet rail, preferably on a on the cabinet rail attached stop strikes.

An alternative embodiment of the invention provides that the housing of the touch-latch fitting is indirectly or directly connected to the carcass rail, and the sliding and / or rotating part of the touch-latch fitting directly or indirectly on the drawer rail, preferably strikes a mounted on the drawer rail stop.

The touch-latch system is interchangeable with a damper integrated in the guide (e.g., damper as in DE-10256133 or EP-03012770.8). This applies in particular to the arrangement of the touch-latch system at the free end of a rail, e.g. the drawer rail. The advantage is that the customer or the fitter can decide "at the last minute" whether he wants to use the damper or the touch-latch system. It may be provided that a touch-latch system be mounted on one side and a damper on the other side.

Preferably, a single touch-latch system per drawer is present, but it can be arranged in different versions on each side of the drawer a particular identical touch-latch system or even several different touch-latch systems at different positions in the drawer or be present to the furniture body. However, preference is given to a single touch-latch system per drawer and an additional element is mounted as a sprung front-gap stop on the opposite side of the touch-latch system.

But to avoid malfunctions, a touch-latch system is mounted in a single guide. With two uncoupled touch-latch systems, it malfunctions when opening outside the trip range.

The trip range is predefined with the position of the touch-latch system and does not necessarily correspond to the entire front panel (depending on the front panel width). For narrow drawers it is the whole front panel, for wide drawers the release on the side with touch-latch is easy too the further you press the touch-latch system, the harder it becomes impossible to trigger (eg with 1200cm wide drawers).

By preferably one-sided equipped touch-latch system must be mounted on the opposite side of an additional element as a sprung front gap stop. Thus, a uniform gap between the front and body over the entire front width guaranteed (important in the closed state, since the touch-latch system requires a larger front gap: about 5 mm instead of only about 2 mm, to push the front to open can). This would be a possibly existing standard automatic retraction pull the opposite side of the front too far.

This is not necessary if there is only one pull-out guide per drawer, which is then arranged at the bottom and in the middle of the drawer.

The attachment to a single touch-latch system is preferably a buffer, e.g. is arranged on the inside of the front panel or generally on the body.

Also, the additional element may be a resilient pressure piece which is mounted in the opposite position of the touch-latch system.

It can be provided that there are two touch-latch systems per drawer (one per pull-out guide).

In one embodiment of the present invention, the two sliding parts and / or rotating parts of the touch-latch hardware are coupled via transmission means (e.g., cables, pulleys, tie bars), preferably under the drawer bottom or behind the drawer back panel.

In another embodiment of the present invention, the two touch-latch systems are independently mounted in the guide.

Independent touch-latch systems with locking work well with narrow ones Drawers, as the release area actually corresponds to the entire front panel.

In particular, the two touch-latch systems are locked in the closed state, which ensures a uniform front gap and eliminates the automatic catch. The drawer can not open unintentionally because it is locked. Normally, it is locked by the automatic retraction.
For wide drawers with 2 touch-latch systems with interlocking it can happen that when pressing (= when opening) one touch-latch system is unlocked and the other one is not pressed because one has pressed outside of the tripping area. If this is the case, you have to press on the side of the still locked touch-latch system and it unlocks. This "catch mechanism" tolerates the false alarms.

The locking of the touch-latch system is carried out in a preferred embodiment of the invention via a resilient hook between the housing of the touch-latch fitting, and the opposite rail.

In an alternative embodiment, the locking of the touch-latch system takes place via a coupling device at the end of the sliding part of the touch-latch fitting and an additional locking within the touch-latch system.

Instead of a automatic retraction, a touch-latch system can be used, preferably on the cabinet rail. Preferably, this touch-latch system has the same external dimensions as the automatic retraction. The touch-latch function is preferably realized via a heart curve. The lock is the same as the automatic retractor, where a hook is tilted and snaps onto one edge of the auto-retractable housing.

If the triggering distance of the touch-latch system is smaller than the feed path of an optional automatic feed mechanism, then the opening path of the drawer is limited, regardless of the weight of the drawer. To open the drawer completely, you must pull it once more. This can be as additional Security feature may be desirable to prevent unintentional too wide opening of the drawer.

However, if the triggering path of the touch-latch system is longer than the feed path of an optional automatic feed mechanism, then the automatic feed mechanism does not hold the drawer closed, but pushes the drawer through the automatic retraction path.

The touch-latch hardware of the principle known touch-latch system may have a particular curve, e.g. Heart curve, 3D curve or any other touch-latch principle have.

In another variant of the invention, the touch-latch system can be mounted on the left or right or in the middle of the drawer, e.g. drilled, e.g. in the drawer bottom or in the frame, or with adapter screwed somewhere, or drilled in the cabinet side. The associated to the touch-latch system stop member is preferably mounted in the body.

There may be two such touch-latch systems in the drawer connected via transmission means or two touch-latch systems which are independent of each other.

According to the invention, the length adjustability of the touch-latch fitting is effected by three different basic variants, namely an adjustment of the entire touch-latch fitting, or else only by an adjustment between defined individual parts of the touch-latch fitting, or by an adjustment of a stop, which cooperates with the touch-latch fitting. Of course, these three basic variants could also be arbitrarily combined.

Preferably, a simple and inexpensive all three previously described variants of the length adjustability of the touch-latch fitting of the touch-latch system is carried out either via an eccentric adjustment, or via a screw adjustment, or via a locking position adjustment. Of course, these three versions of the adjustment could also be arbitrary with each other be combined. The longitudinal adjustment has the advantage that the position of the front of the drawer can be adjusted.

The eccentric adjustment of the touch-latch fitting has either an eccentric screw with at least one cam or a worm screw with spiral screw winding. The angle of rotation of the eccentric screw is between 90 ° and 180 °, but up to a maximum of 360 °, the angle of rotation of the screw between 360 ° and 540 °, but can also be 720 ° or more, depending on the desired adjustment.

The screw adjustment of the touch-latch fitting has a threaded sleeve, which is screwed into or on the housing of the touch-latch fitting, or has a threaded spindle of a stop which with a sliding part and / or a push-off of the touch-latch -Beschlages length adjustable is connected by screwing movements.

The means for length adjustment, in particular eccentric adjustments of the touch-latch fitting preferably act between the sliding part of the touch-latch fitting and arranged at the front free end of the sliding part stop. The means for length adjustment, in particular screw adjustments preferably act between the housing of the touch-latch fitting and its sliding part, or between two components of the stop at the front free end of the touch-latch fitting.

In another variant of the invention, it may be provided that the spring force of the spring of the touch-latch fitting is designed to be adjustable. For example, For a heavy duty drawer, a spring with a larger spring force is advantageous, for a drawer that has only low capacity, a touch-latch fitting spring with a relatively low spring force is sufficient.

The spring force can be adjusted either in stages, or stepless. If the touch-latch-fitting spring is adjustable in predefined stages, the end of the spring, for example, hangs at different latching steps in the housing of the touch-latch fitting. With infinitely variable adjustability of the touch-latch fitting spring this is adjustable, for example via an adjusting screw, which is attached to the bottom of the housing of the touch-latch fitting.

A Vorbestückung is also conceivable, i. for a heavy duty drawer or door, a touch-latch fitting is used with a spring with a large spring force, and for a normal or light drawer or door, a touch-latch fitting is used with a spring with a lower spring force.

Of course, a stepless and gradual adjustability of the touch-latch fitting spring within a touch-latch fitting or drawer can also be combined.

In the following, the invention will be explained in more detail with reference to drawings illustrating several execution paths. Here are the drawings and their description further features and advantages of the invention.

In Fig. 1 to 4, a drawer slide 1 touch-latch system with integrated touch-latch fitting 5 is shown. The housing 6 of the touch-latch fitting 5 is connected to the drawer rail 2 and is temporarily in contact with the carcass rail 4 via the stop 9. The connection between the housing 6 of the touch-latch fitting 5 and the drawer rail 2 can through Known methods are: snap connection, rotary connection, insertion technique, screw connection, bayonet connection, Renkverbindung, etc ....

There are known drawer slides that have an integrated damper (see DE-10256133 or EP-03012770.8). The two systems (touch-latch and damper) can be replaced as required, if they have the same size.

The arrangement of the touch-latch system in the guide does not have to be limited to that in FIGS. 1 to 4!

In Figs. 1 and 2, the drawer slide 1 is closed or has just been opened. The touch latch fitting 5 is still (or ready) in the open state. The sliding part 7 of the touch-latch fitting 5 is pulled out and not in contact with the stop 9 of the carcass rail 4th

In Fig. 3, the drawer slide 1 is in the closed state, as well as the touch-latch fitting 5. The sliding part 7 is in contact with the stopper 9. The distance between the housing 6 of the touch-latch fitting 5 and the stopper 9 is comparable to the front gap 24 in FIG. 11.

In Fig. 4, the depressed position of the touch-latch fitting 5 can be seen. Among other things, it corresponds to the process of opening the drawer when the front panel of the drawer is pressed. The distance between the housing 6 of the touch-latch fitting 5 and the stop 9 is equal to zero (the sliding part 7 of the touch-latch fitting 5 is retracted), so that the unlocking of the system can take place.

FIG. 5 shows a first principle of a touch-latch system.

The housing 6 has on its inside eight longitudinally extending grooves 10, which are arranged at a distance of approximately 45 ° around, and wherein each second groove 10 is formed deeper. The grooves 10 do not extend over the entire length of the housing. 6

The rotary member 8 has four projections 13 offset by 90 °, each having an oblique edge 14 at its end. The inclination of these edges 14 corresponds to the inclination of the edges 12. The projections 13 can be guided displaceably only in the deep grooves 10 of the housing 6.
The rotary member 8 is located in the housing 6 between the lid 17 and the grooves 10th

The sliding part 7 has eight projections 11 which engage in all the grooves 10 of the housing 6, since these projections 11 are only as high as the four grooves 10, which are not very deep. The sliding part 7 is guided displaceably in the housing 6.
At the end of the disk part 7, eight edges 12 (like a sawtooth-like running surface) are provided.
The other end of the disk part 7 forms the stop, which comes temporarily in contact with the stopper 9.

The spring 15 is preferably in the rotary part. 8

When pressing the sliding member 7 against the stop 9, the edges 14 of the projections 13 come from the rotary member 8 with the edges 12 of the disk part 7 in contact and are rotated accordingly by a partial amount. If the force of the user pushes in or the drawer is closed, the sliding part 7 is again moved in the opening direction due to the spring force of the spring 15, and the rotary part 8 becomes one more by the contact of the edges 14 with the edges 12 Partial amount turned. The total rotation of the rotary member 8 when opening or closing is in this case 45 °.
In the closed state of the touch-latch system, the projections 13 from the rotary member 8 are outside the grooves 10 of the housing 6. In the open state of the touch-latch system are the projections 13 of the rotary member 8 in the grooves 10 of the housing. 6

The number of grooves, edges, and protrusions (45 ° / 90 °) is not the only possibility, there may be other divisions (e.g., 30 ° / 60 °).

The mounting device 16 on the housing 6 of the touch-latch fitting 5 is used for mounting on the drawer rail second

In Fig. 6 and 7, a second principle of a touch-latch system is shown. It is a backdrop principle with a heart curve.
The link pawl 20 is rotatably mounted in the housing 6 and runs in the gate 18. The Verrieglungsmechanismus is given by the shape of the heart curve of the gate 18. The link pawl 20 runs on one side of the curve of the link 18 when the user presses the touch-latch system or the front panel or when the drawer is closed. When the force subsides, the link pawl 20 is locked by the force of the spring 15 in the locking position 19 of the link 18. After unlocking, the link pawl 20 continues in the curve until it reaches the straight part of the gate 18 again.

The mounting device 16 on the housing 6 of the touch-latch fitting 5 is not shown. The end of the sliding sleeve 7 can strike the stop 9.

FIGS. 8 to 10 show a third principle of a touch-latch system. It is a backdrop principle with a 3D curve.
The link pawl 20 is mounted on the housing 6 via a first arm and its other arm runs in the gate 18. The Verrieglungsmechanismus is given by the shape of the 3D curve of the gate 18. When locking the crank pawl 20 engages in the locking position 19 of the link 18, when unlocking the link pawl 20 is removed from the detent position 19.

The mounting device 16 on the housing 6 of the touch-latch fitting 5 is not shown. The end of the sliding sleeve 7 can strike the stop 9.

Referring now to Figures 11 and 12, there is shown a drawer 21 having a "complete" built-in touch-latch system. The drawer 21 is located in the body 22nd

On one side of the drawer 21 is a touch-latch fitting 5 and a stop 9 in the drawer slide 1 (not shown here) integrated. The installation of a touch-latch system requires a larger front gap 24 between the front panel 23 and the body 22, as with conventional drawers with handle, so that the front panel can be pressed for the opening process. The front gap 24 may be about 1.5 to 6 mm, preferably 5 mm.

The side of the drawer 21 without touch-latch system is but fed by the usual built-automatic retraction (not shown) more. To eliminate this disadvantage, e.g. a buffer 25 is installed between the front panel 23 and the body 22 (either on the front panel 23 or on the body 22). The size of the buffer 25 corresponds to the size of the front gap 24.

Another variant is the installation of a resilient pressure piece on the opposite side of the touch-latch system (at the same position). For example, a cylinder is integrated into the guide only with spring and sliding sleeve.

Another possibility would be the installation of a resilient pressure piece in the automatic retraction so that it is not completely retracted or the displacement of the bolt, which engages in the driver of the automatic retraction.

Figs. 13 and 14 show a locking mechanism with a clip system.

In Fig. 13, a resilient hook 30 is attached to the housing 6 of the touch-latch fitting 5, which locks when retracting the drawer in the recess 29 of the carcass rail 4. Now, when the drawer is pulled in to trigger the touch-latch system, the spring force of the touch-latch system is sufficient to push the resilient hook 30 from its lock.
The length of the recess 29 corresponds approximately to the length of the front gap (path that you can press).

In Fig. 14, the reverse solution of Fig. 13 is shown. The resilient hook 31 is mounted on the carcass rail 4 and may e.g. are mounted in the recess 29 and locked in the recess 32 of the housing 6 of the touch-latch fitting 5 when retracting the drawer. Now, when the drawer is pulled in to trigger the touch-latch system, the spring force of the touch-latch system is sufficient to push the resilient hook 31 from its lock.

In Fig. 15, another locking mechanism is shown. At the end of the sliding part 7 is a coupling device 33, preferably a hook, and preferably a pad 34 is provided, which is not absolutely necessary if the sliding part 7 has a different geometry.
The block 34 acts as a stop for the sliding part 7 against the stop 9 and the hooks of the coupling device 33 engage behind the stop 9, as with the damper DE-10256133). About the coupling device 33, the rails (drawer rail 2 and cabinet rail 4) are held to each other in position when the drawer is closed.

Fig. 16: When retracting the touch-latch fitting 5 and the sliding part 7 with the knob 35 in the recess 36 of the housing 6 is additionally locked (push-pull and release are otherwise always locked).
When the touch-latch system is triggered, the spring force of the touch-latch fitting 5 is sufficient to press the knob 35 out of the recess 36.

Fig. 17 shows a variant for the additional lock. The sliding part 7 is always connected to the rotary part 8 via a plug connection (locking pin 37). The triggering works as in FIG. 16.

FIG. 18 shows another variant of the integrated touch-latch system.
The touch-latch system is integrated or mounted in the drawer frame 26 and abuts the stopper 27 on the body 22.

One way (not shown) is that there is only one touch-latch system on one side of the drawer 21, and preferably on the other side a buffer 25 between the body 22 and front panel 23 or a resilient pressure piece in the shop side without touch-latch system.

Another possibility according to FIG. 18 is that two touch-latch systems are present in the drawer, one per drawer frame 26, which are both interconnected with transmission means 28, so that there is synchronization and no false triggering. In Fig. 18, only a part of the drawer is shown with this variant.

It is also conceivable that two touch-latch systems are integrated in the drawer slide (one touch-latch system per drawer slide) and that they are connected to transmission means (e.g., the transmission means pass under the drawer bottom). With this variant, the triggering range becomes larger (on the entire front panel) and no false triggering occurs.

Figures 19 and 20 show another embodiment of the present invention with a touch-latch fitting 5, which is integrated in the body side wall 22 and rests with its front free end on the inside of the front panel 23, while the drawer 21 is closed. A separate stop 9 or 27 as in the previous embodiments can therefore be omitted. Of course, once again only one touch latch fitting 5 may be present on one side of the drawer 21, or two, one in the left and one in the right side wall 22 of the body, which in turn may be mechanically coupled to each other via transmission means for synchronization purposes but can work independently. Also, in turn, a lock on this touch-latch fitting 5 may be provided so that a automatic feed can then be omitted.

FIG. 21 shows a length adjustability of the touch-latch fitting 5. The length adjustment is necessary in order to adjust the front position so that all fronts in the body 22 are in the same plane when the drawers 21 are closed. For this purpose, an adjustable stop 38 is mounted at the front free end of the sliding part 7, which is adjustable via an eccentric 39, for example in the form of a slotted screw in the length 40 in the longitudinal extension of the touch-latch fitting 5. Of course, are of this inventive idea includes all length adjustment, such as telescopic adjustment, interchangeability of the sliding part 7 with shorter / longer sliding parts etc .. The typical adjustment 40 is about ± 2 mm.

FIGS. 22-25 show a touch-latch fitting 41 according to a second embodiment, which in turn includes the housing 6, in which the sliding part 7 is received in a longitudinally displaceable manner, at the front free end of which there is a stop 42. By means of a worm screw 43 within the stop 42, this is moved relative to the sliding part 7 in the longitudinal adjustment directions 40. The sliding part 7 engages longitudinally displaceable in the U-shaped profiled stop 42, which has at the free ends of the U-legs inwardly directed hook-shaped projections 44, so that the sliding part 7 to the stop 42 is exclusively axially displaceable, but not transversely or in other directions. Within the U-shaped profiled stop 42, a further recess 45 is introduced, for receiving the worm screw 43, the tool lug 46 is freely rotatably mounted in a bore 47 approximately centrally in the recess 45 of the stopper 42. On the underside of the sliding part 7 more (here 3 pieces) knobs 48 are arranged axially one behind the other, in the interstices 49, the spiral screw winding 50 of the worm screw 43 engages. Now, if the worm screw 43 (not shown) rotated by means of a tool in the approach 46 tool (left or right around), then runs the worm winding 50 in the spaces 49 between the nubs 48 and thus causes a relative displacement between stop 42 and sliding part. 7 in the adjustment 40. On the housing 6 of the touch-latch fitting 41 are in turn fastener 16 (see Fig. 5) for the direct or indirect attachment of the touch-latch fitting 41 on the piece of furniture, eg on the drawer rail 2, and optionally Latching means for latching the touch-latch fitting 41 on the piece of furniture, eg on the drawer rail 2. Advantage of the length adjustment of the touch-latch fitting 41 with the screw screw 43 with spiral screw winding 50 according to FIGS. 22-25 with respect to the length adjustment of the touch panel Latch fittings 5 with eccentric screw 39 (not shown cam) of Figure 21 is the longer adjustment of the worm screw 43, since in the example about a rotation of 540 ° the worm screw 43 lead to an extension or shortening, in the eccentric screw 39, however, only a rotation of 180 °, for example.

FIG. 26 shows an exploded view of a third embodiment of a touch-latch fitting 51 that is almost identical to the embodiment of the touch-latch fitting 5 according to FIG. 5, so that all the reference signs listed there also designate the same components in FIG. In contrast to the embodiment according to Figure 5, however, a sleeve 52 is provided, which contains the touch-latch contour (2D / 3D Koulisse), and which in the housing 6 via a thread (for example, fine thread). is screwed in. Depending on the depth of engagement of the sleeve 52 in the housing 6, different front gaps between front panel 23 and front of the body 22 result.

In Fig. 27, a fourth embodiment of a touch-latch fitting 53 is shown, wherein the stopper 54 is formed in two parts and includes a threaded spindle 56 and a Abdrücker 55. The threaded spindle 56 can be screwed into the Abdrücker 55, so that depending on the depth of engagement different front gaps between the front panel 23 and front of the body 22 result.
