Description

The present invention relates to a fitting for doors, flaps and pull-outs of furniture, especially kitchen furniture, that of successive Operations are moved alternately to an open or closed position.

Such fittings are known for example as locking devices, by means of which a door, flap or pull-out is held in a closed position is and only after pressure on the front of the door, flap or pull-out can be opened again. Such touch-Latsch fittings are particularly then used when the door, flap or for optical or functional reasons the pull-out cannot be provided with handles. In order to open the To reach the piece of furniture, the user actuates the front of the door, flap or the pull-out by slight pressure in the closing direction, which makes the touch-laces Fitting switches to the release position and the door, flap or the Excerpt can be opened.

It is the object of the present invention to provide a simple, robust and reliable fitting for doors, flaps and pull-outs of furniture, especially kitchen furniture.

This task is based on a generic fitting solved that the fitting comprises a first and a second locking element, which in a first position (closed position) in such a form-fitting manner Are connected that the mobility of the second locking element in a first direction is blocked, and that a release element is provided, through which the first locking element when the second moves Locking element in a direction opposite to the first direction a movement in a direction that is oblique or perpendicular to the first direction experiences second direction, causing the locking elements in a second position (Open position) are moved, in the movability of the second Locking element is guaranteed in the first direction.

The first direction corresponds, for example, to the direction of the opening movement a door, flap or pull-out. The second direction is different can run vertically or at an angle.

In the first position, the two locking elements are in such a way with each other in contact that the second locking element no longer in the Opening direction of the door, flap or pull-out can be moved because this is held by positive locking by the first locking element. After operating the fitting, the locking elements become relative moved to each other in a second position in which a movement of the second Locking element in the first direction is possible, d. H. in which the door The flap or the pull-out can be opened.

Starting from the closed position, the second locking element is in a direction opposite to the first direction, i.e. in the closing direction of the door, Flap or the extract, moves, the release element causes that other of the locking elements in the second, for example to the first Direction oblique direction, is moved. This relative movement has as a result, the second locking element is now free in the first direction can be moved.

According to a preferred embodiment of the present invention provided that the first locking element by a in the fitting pivotally received pawl is formed, which has a groove, and that the second locking element is formed by a rod that one in the Groovable projection includes. When the door closes, flap or the pull-out, the projection of the rod is moved into the groove and runs through this until finally a position is reached in which the rod is no longer in Opening direction is movable. Is now on the furniture front by the user exerted a force acting in the closing direction, the rod is in one of the first Direction opposite direction and the jack in the second direction moves so that the projection of the rod from the aforementioned area of Groove is removed and moved into groove areas where movement of the second Locking element in the first direction is possible.

It is particularly advantageous if the release element comprises a spring which is on the first locking element exerts a force acting in the first direction. Due to the spring force, the first locking element is always parallel to the aligned in the first direction. If the second locking element in one of the moves in the first direction opposite direction, the spring force leads to that the first locking element, for example the pawl, in such a way deflected into a centered position that the projection of the Bar is moved to areas of the groove where there is a release of the bar and pawl is possible.

According to a preferred embodiment of the present invention is a sleeve provided, which is acted upon by the spring on its inside and with Your outside is connected to the first locking element.

The release element can be provided on the pawl with an approach have inclined surface relative to the first direction, by the projection provided on the rod is moved in the second direction. The sloping surface thus has the effect that as soon as the Projection of the rod comes into contact with this, a movement of the pawl into the second direction, so that the projection from the The closed position of the groove can be removed.

In a further embodiment of the present invention it is provided that the Jack has an approach surrounded by the groove, which has a concave area has, in which the projection of the rod in the first position is held.

The second locking element can be formed by a rod which in the Fitting is movably received in the first direction and there can be one or several springs can be provided, through which one on the rod in the first Directional force is exerted. The bar thus serves to open the door, Flap or pull-out to open a gap, thereby engaging with the Hand and thus opening the door, flap or pull-out is possible. The Rod is not attached to the door, flap or pull-out, but is located always in the fitting in which it is movably received. The spring force causes the fitting after its operation and after a change of Locking elements in the release position on the door, flap or the Excerpt exerts a force acting in the opening direction.

In a further embodiment of the present invention it is provided that the second locking element by one with the door, flap or the extension of the Furniture connectable pin is formed. The pin can thus be firmly attached to the door, Flap or the extract can be arranged and have a projection which in a corresponding groove of the pawl can be accommodated.

Fig. 2 shows an illustration of the pin 20 ', which is L-shaped and with a leg mounted on the inside of a door, flap or pull-out becomes. In the end region of the other leg, the projection 22 is provided can be inserted into the groove 12 of the pawl 10. Will the door, flap or the pull-out closed, the projection 22 is inserted into the groove 12 and runs through first the upper beveled area of FIG. 1b (below) Groove 12 finally up to the upper of the semicircular recesses of the groove 12 guided. If the user then lets go of the furniture front, one leads for example spring arranged in the hinges of the door or flaps, that the projection 22 on the concave region 17 of the extension 16 and is held there. The door, flap or pull-out is now in one first position (closed position) in which an opening due to the positive Engagement of the projection 22 and the approach 16 is prevented.

If the user now wants to open the piece of furniture from this position, he exerts a force acting in the closing direction on the door, flap or pull-out out, whereby the projection 22 on the serving as a release element obliquely extending surface 15 of the neck 14 is pressed. The one in the first Closing movement of the Projection 22 leads to a due to the bevel of the approach 14 Movement of the pawl 10 in a second direction predetermined by the slope, whereby the projection 22 finally into the lower of the circular Recesses of the groove 12 is performed (see Fig. 1b (below)). Leaves the user then go the furniture front, the projection 22 passes through the lower straight Area of the groove 12 and is finally released from the groove 12, so that can open the piece of furniture.

Fig. 3 shows a further embodiment of the fitting according to the present Invention. 3a shows the housing halves 50 and 60 as individual parts as well as in an assembly. On the housing half 60 serving as the lower part the approach 62 is arranged, which serves to receive the pivotable pawl 10.

3b shows a rod 20 designed as a slide with a projection 22 and with Approaches 24 for holding the springs 40 (see Fig. 3e). The springs 40 are also held by the approaches 64 shown in Fig. 3a.

Fig. 3e shows the assembly of the fitting without the housing cover. On the approach 62 is pivotally received the pawl 10. In the area to the left of Approach 52 extends the spring 30 from the sleeve shown in Fig. 3d 32 is surrounded and the one on the pawl 10 facing right into the first Exerts directional force.

In the groove 12 of the pawl 10, the projection 22 is designed as a slide Rod 20 added. The rod 20 is in a first direction and in one this opposite direction is movable back and forth in the fitting, however cannot be removed from the fitting. One acts to the right on the rod 20 directional force applied by the springs 40 which causes the rod 20 always experiences a force acting in the open direction of the fitting.

The approach 16 has a concave region 17, in the upper end region the protrusion 22 in the first position (closed position) of the two Locking elements is held. The springs 40 exert a force on the rod 20 force directed to the right, acting in the first direction, but due to the positive contact between the concave region 17 of the Approach 16 and the projection 22 does not lead to movement of the rod. Starting from this position, the rod will move slightly according to Fig. 3e Pressed on the left, as is the case when the furniture front is pressed, the Projection 22 removed from the concave portion of the neck 14 and the pawl 10 pivots clockwise. This will caused that the force of the spring 30 acts on the pawl 10, which leads to that the pawl 10 in a first direction, d. H. in a direction parallel to Direction of movement of the rod 20 is aligned. The pawl 10 from this Moved out position, the spring 30 constantly exerts a restoring force that this leads that the pawl 10 is returned to the position shown in Fig. 3e. Due to the spring force of the spring 30, the pawl 10 exercises when moving the rod 20 in a first direction, a pivoting movement in a second direction leads to the protrusion 22 emerging from the concave region 17 of the extension 16 is moved, as can be seen from Fig. 3e. In this way, the Shorten the actuation path when unlocking the fitting. The projection 22 now runs through the groove 12 to the end of the groove due to the spring force of the springs 40, whereby the rod 20 is extended at the same time.

With an insertion movement of the rod 20, the projection 22 passes through the in Fig. 3e lower, oblique area of the groove 12 and is finally released the furniture front held in the concave area 17 of the approach 16.

Figure 9 shows a sequence of different positions of the rod 20 and the Jack 10 during the closing process of a door, flap or a pull-out as well as during the opening process after unlocking the rod 20. The illustration 9 a) sets the fitting according to the invention when the door is open, Flap or an opened extract. The rod 20 with projection 22nd is in its extended position and is in this by the in Springs 40 acting in the opening direction are held. When closing the not Door, flap or the extract shown, the rod 20 is now in the Housing of the fitting inserted, the projection 22 with the approach 16 of the pawl 10 comes into contact and, as can be seen from FIG. 9 b), the pawl 10 slightly up, d. H. pivoted counterclockwise.

If the rod 20, which is designed as a slide, is pushed in further, the rod passes through Projection 22 continues the groove 12 and finally reaches that part of the groove 12 which between the shoulder 16 and the opposite projection 11 on the Pawl 10 extends. Due to the acting on the pawl 10 by the spring 30 The pawl 10 experiences a restoring force at this moment Swivel motion, d. H. a clockwise swivel motion until the Projection 22 finally received in the concave region 17 of the pawl 10 is. Fig. 9 c) provides the fitting with the door, flap or closed closed pull-out. The fitting is in the closed position. The Movement of the rod 20 in the opening direction is blocked. The jack 10 is in a slightly opposite to the starting position according to FIG. 9 a) upward pivoted position.

Is now one on the front of the door, flap or pull-out by the user 9 directed to the left, that is, acting in the closing direction force exercised, this leads to the rod 20 and thus also the projection 22nd can also be moved to the left, with the result that the projection 22 from the position shown in FIG. 9 c) is removed. This leads to the pawl 10 due to the force of the spring 30 in its horizontal starting position is pivoted back, as can be seen from Fig. 9 d). Fig. 9 d) thus represents the fitting immediately after the triggering process, i.e. immediately before the door, flap or pull-out opens. By the force of the springs 40 is now after the release, the rod 20 designed as a slide to the right, d. H. moved in the opening direction, with the projection 22 through the upper region the groove 12 runs and the pawl 10 is pivoted as shown in FIG. 9 e). The projection 22 now runs freely through the groove 12 and then leaves the pawl 10. The rod 20 is so far due to the force of the spring 40 moved right until the position shown in Fig. 9 a) is reached. The Opening force for the door, flap or pull-out is provided by the spring-loaded applied as a rod 20 executed slide.
