Description

The present invention relates to an opening device for a pull-out, in particular for drawers, with a guide housing on which a latch is slidable along a guide, wherein the latch is fixed along the guide in two spaced positions and has a receptacle for an activator with a movable rail of the pull-out guide is coupled, and a latching mechanism is provided to fix the latch in a closed position against the force of a spring, and a latching mechanism.

A pull-out guide is formed from a guide rail fixed to the furniture carcass and a running rail fixed to the pull-out element, as well as, if appropriate, an extending center rail.

The EP 766939 discloses an opening and closing device for a drawer, in which the back of the drawer, a lever is arranged, which can be fixed to a latching mechanism. For this purpose, the lever is moved along a control cam against the pressure of a spring. The spring and the control cam are spaced apart from each other and contacted the spring in the event of engagement end of the drawer. As a result, control cam and spring to each other Be tuned, especially with regard to the location and arrangement of a drawer in the furniture body. In addition, the space requirement of the locking mechanism is comparatively large.

In the EP 743032 a further development of the locking mechanism for a drawer slide is shown, in which a coupled with a drawer activator with a latch is connectable. The latch is guided on a guideway of a housing and can be locked in a closed position of the drawer against the force of a spring. As a result, the drawer is moved in the opening direction in an unlocking of the latch. The guidance of the latch along the guideway to the housing leads just in jerky or jerky movements to considerable material loads. This limits the life, whereby the permanent tensile load of the spring can lead to fatigue. The open housing can also affect the contamination of the leadership of the latch.

The EP 1845821 discloses a pullout guide opening and closing device in which a cam on a track rail is coupled to a latch member which is guided along a latch housing. The latch member is coupled to a detent mechanism that can latch the latch member in two spaced apart positions. For this purpose, the pawl housing has a guide track on a housing in which a pin of a coupling rod is guided. The coupling rod is biased by a spring and coupled at one end to the latch member. Again, the leadership of the coupling rod along a cam to the fact that the material loads during pivoting are significant. Especially with shock loads, damage and malfunctions can occur here. In addition, the life of such a Rastmechanismusses is limited.

It is therefore an object of the present invention to provide an opening device for a pull-out, which has a low material wear in a simple and compact design.

This object is achieved with an opening device for a pull-out guide with the features of claim 1 and a latching mechanism with the features of claim 6.

According to the invention, the latching mechanism has a substantially cylindrically shaped housing with a control cam along which a control element is displaceably guided in a longitudinal direction of the housing and is rotatable about a longitudinal axis. This allows the control slide in the housing along the control cam, with only low material loads are present. Because the cam can guide the control smoothly, since this is both flexible and rotatable, so that no bending loads or greater frictional forces can occur. In addition, the control is arranged protected in the housing, so that even dirt can not affect the function of the locking mechanism.

According to a preferred embodiment of the invention, a rod is movable by the control, which is coupled at the end with the latch, Thus, a substantially linear movement can be transmitted to the latch, wherein the rod can be guided almost sealed in the housing of the latching mechanism, so that this is particularly protected. In addition, the mechanism of the latch and the mechanism of the latching mechanism can be provided spaced apart from each other, so that the opening device can be mounted in a furniture carcass even in confined space.

For a good guidance of the control this may be annular. Thereby, the control may be guided on its outer peripheral surface, wherein at least one radially projecting projection may be provided, which then engages in the control cam. It can also be formed two or more projections, wherein a plurality of contact surfaces of the control cam can provide a guide of the control.

For the possibility of effective production of the housing with a control cam, this can be designed in several parts, wherein a cylindrical housing part is provided, to the at least one outer housing part for training the control cam is at least partially inserted. The control cam can be formed by an edge portion which is formed on the inserted part of the outer housing part. The inserted portion may be inserted sleeve-shaped in the cylindrical housing part, wherein the edge portion then cooperates with a projection or a plurality of projections on the control.

Preferably, an outer housing part is at least partially inserted on each side of the cylindrical housing part. As a result, the opposite housing parts can form a completely or partially closed control cam on opposite sides.

In a further embodiment of the invention, a control cam arranged adjacent to the inner wall of the cylindrical housing part is provided on the at least one outer housing part, which cam cooperates with the at least one projection of the control element. The cam can be formed thin-walled and be supported on the cylindrical outer housing part, so that a secure guidance of the control is ensured.

For an effective assembly, the at least one outer housing part can be locked to the cylindrical housing part.

In a preferred embodiment of the invention, an energy accumulator for biasing the latch is provided in the housing. The energy accumulator can be supported as a compression spring end to an outer housing part.

Preferably, the closed position of the latch is adjustable via the latching mechanism. As a result, the closed position of the front panel of a drawer can be adjusted accordingly, for example, for a flush alignment. Thus, an adjustment of the trip path to ensure the function is possible. Due to the manufacturing conditions in furniture large tolerances are accepted in order to achieve high reliability of the opening device can be made adjustable. Because the front panel of a drawer is on the pull-out, the activator and the latch with the Locking mechanism coupled so that mounting tolerances on the locking mechanism can be compensated. To adjust the closing position, at least one housing part, which forms a part of the control cam with a latching receptacle, can be adjusted relative to the guide housing of the latching pawl. Because for the adjustment of the latch, it is sufficient if the corresponding locking receptacle of the locking mechanism is adjusted relative to the guide housing. A stepless adjustment is made possible, for example, when an outer housing part is adjustable via a thread in the longitudinal direction.

For a compact design of the latching mechanism, the energy accumulator can be designed as a compression spring which acts on the latching pawl via the rod arranged in the housing. The compression spring can be supported on a disc which is coupled to the rod, so that the rod is guided linearly within the housing. Due to the smaller diameter relative to the control with the radially protruding projections, the control cam does not act on the disc. As a result, the energy storage is largely protected from external environmental influences.

The opening device does not have to be supplemented by a locking device, which allows cost savings and a very compact design. Known from the prior art opening device must be supplemented by a locking mechanism via a tension spring to prevent accidental opening of the drawer. The tumbler is via a projection on the control element, which is fixed in the closed position in a locking receptacle of the control cam.

An end stop is formed via a slot stop on the latch and a slot stop on the guide housing. Regardless, the distance of the front panel relative to the furniture body can be adjusted by the adjusting device to ensure the function of the opening device.

The housing of the opening device can also be made in one piece, for example with a film hinge. On the other hand, it is conceivable with a lost slot, like a waxy kernel, to work. It is also conceivable to produce the housing from two halves. Other manufacturing methods can be used.

The locking mechanism according to the invention is preferably used for opening devices for drawer guides, but can also be used for other movable furniture parts, such as flaps or sliding doors. In this case, the latching mechanism may also have a movable stop, which is not fixedly connected to a latch or the movable furniture part. The stop is preferably arranged terminally on the rod of the latching mechanism. The latching mechanism can move a movable furniture part from a first to a second position via the movable stop. Preferably, the locking mechanism is used for ejecting movable furniture parts. Possible applications include e.g. also household appliances such as ovens or refrigerators.

The opening device also includes a housing 11 having a latching mechanism to fix the latch 7 in two spaced-apart positions. One of these positions is the closed position in which the detent pawl 7 is locked against the force of a spring. The latch 7 is coupled via a rod 10 with the latching mechanism in the housing 11.

The terms "open" and "close" refer to an end position of the drawer 1 in a furniture body in which the drawer is retracted and can be opened or closed accordingly. However, the "closed position" may also be another position in which the component to be fixed is held by the latching mechanism.

In FIG. 3 the latch 7 is shown without the activator 9, which engages in a receptacle 90 on the latch 7, which is formed by two spaced-apart projections 91 and 92. The guide 8 on the guide housing 6 has at one end a bent portion 80, on which the latch 7 is pivoted to release the activator 9. From this position, the running rail 4 can be moved to a fully extended position. The latch 7 is further locked by a latching mechanism in a closed position of the pull-out or the drawer 1.

In FIG. 4 the components of the housing 11 and the latching mechanism are shown. The housing 11 comprises a sleeve-shaped middle housing part 12, to which an outer housing part 13 is attached. Here, a sleeve-shaped portion 14 engages with a smaller outer diameter in the sleeve-shaped housing 12 a. At the section 14, an edge 15 is formed at the end, which forms part of a control cam. The outer housing part 13 has at the portion 14 further projections 16 which are engaged in corresponding recesses 17 on the sleeve-shaped housing 12. The locking recesses 24 are used to set the housing 11 to the guide housing 6 by means of locking lugs 25. It is also a force, positive and / or cohesive fixing of the housing 11 to the guide housing 6 conceivable.

On the opposite side of the sleeve-shaped housing part 12, a second outer housing part 20 is provided, which also has a portion 21 with a reduced outer diameter, which is inserted into the sleeve-shaped housing part 12. At the portion 21, an edge 22 is provided, which also forms part of a control cam. At the portion 21 projections 23 are further formed, by means of which the housing part 20 can be latched to the sleeve-shaped housing part 12. For this purpose, corresponding recesses 18 are provided. An inner peripheral wall 19 of the sleeve-shaped housing part 12 surrounds the sections 14 and 21 of the outer housing parts 13 and 20. The outer housing part 20 has latching recesses 24 for fixing the housing 11 to the guide housing 6.

Furthermore, a rod 10 is provided in the housing 11, the end having a spherical portion 26 which is latched with the latching pawl 7. On the opposite side, a disc 27 is concentrically fixed to the rod 10, which serves for the end-side support of a spring 28. Further, on the opposite side of the disc 27 to the spring 27, an annular control member 30 is pushed onto the rod 10, which comprises two radially outwardly projecting projections 31. The control element 30 is in the housing 12 and rotatably disposed about the rod 10. Thus, a uniform force distribution is ensured within the opening device, tilting or jamming of the opening device is thus avoided.

In FIG. 5 the middle sleeve-shaped housing part 12 is shown, in which two each of the inner wall arranged regions of the diametrically opposed control cams 33 are shown, which correspond in their sections 15 and 22 with the sections 15 'and 22' of the housing parts 13 and 20 and thus a form circumferential groove-like cam 33. The control cam 33 shown corresponds to the path of movement of the projections 31 on the control element 30 when opening and closing the drawer 1.

The FIG. 6 shows the assembly shown transparently. Thus, the circumferential groove-like cam 33 can be seen.

An end portion of the rod 10 with the control 30 is the FIG. 7 again. In the FIG. 8 as well as in the FIG. 11 are the two radial projections 31 on the control 30 recognizable. The sectional drawing FIG. 9 gives the view of the bead 37 on the rod 10 and the groove 38 in the control member 30 for rotatable mounting and longitudinal fixation of the control 30 free.

An alternative embodiment of the end portion of the rod 10 with the control 30 'is the FIG. 10 again. Here, a snapped into a groove 44 spring washer 39 for rotatable mounting and longitudinal fixation of the control 30 'is shown. The sectional drawing FIG. 12 gives the view of the spring washer 39 and the groove 44 in the rod 10 for rotatable mounting and longitudinal fixation of the control element 30 'free.

The function of the latching mechanism will be described below with reference to FIGS FIGS. 13A to 13F explained in more detail.

In FIG. 13A the locking position is shown in the closed position, in which the locking mechanism 30 locks the control member 30 against the force of the pressurized spring. The control 30 is supported on the disc 27, over which the rod 10, the latch 7, and engaging in position 90 activator 9, and thus the running rail 4 and the drawer 1 is fixed. In the closed position, the radially projecting projections 31 in the pressure spring side remote turning point of a recording at the tips of the protruding portions 15 are held. In the illustrated embodiment, two projections 31 and 31 'are provided on opposite sides of the control element 30, both of which are fixed in corresponding latching receptacles.

In order to release the latching mechanism from the closed position, is accordingly FIG. 13B the drawer 1 and thus on the latch 7 wherein the activator rests on the projection 92, and the rod 10 along its longitudinal axis 50 in the direction of the spring 28 and pushed the spring 28 further compressed. When inserting the rod 10, the control element 30 is rotated, since the two projections 31 slide on the flat-inclined side of the section 15 'to the spring 28 facing turning points, which is formed by the edge 15.

Below is then accordingly FIG. 13C the drawer 1 is released, due to the spring force, the projections 31 of the control element 30 come to rest on the portion 15 of the control cam 33 but no longer slide back into the locking receptacle 40 at the top of the section 22, but past a tip 41 of the control curve are guided so that the rod 10 is pressed in the opening direction due to the force of the compression spring 28 until the in FIG. 13D shown position is reached. In this position, the control element 30 bears against a stop 60 which is formed on the housing part 20. The stopper 60 may be guided in the sleeve-shaped guide 32, the rod 10, wherein the rod 10 has a smaller diameter than the control element 30. The drawer 1 can now be gripped from the slightly open position on the front panel and moved further in the opening direction. In the in FIG. 13D shown position, the latch 7 releases the activator 9 on the running rail 4 due to the arrangement in the bent end portion 80. When the drawer 1 is to be closed again from the open position, the activator 9 abuts against the projection 92 and via the latch 7, the rod 10 is pressed against the force of the spring 28. This will also the control member 30 moves within the cam, since the control member 30 is coupled in the axial direction with the rod 10.

Shortly before reaching the fully retracted position of the drawer 1 ( FIG. 13F ), the control curve begins to act on the edge 15 'of the housing part 13 on the radial projections 31, so that the annular control element 30 is rotated about the longitudinal axis 50. Characterized lie in the final position, the projections 31 of the compression spring 28 facing turning points formed by the projections 15 ', opposite locking receptacles 40 at the top of the edges 22 fixed. When you release the drawer 1 then moves due to the force of the spring 28, the control 30 on the locking receptacle 40, formed by the edge 15, to, wherein the projections 31 and 31 'come into contact on a run-up slope 43 of the locking receptacle 40 and thereby the Move back to cause a further rotation of the control 30. Subsequently, the locking mechanism is again in the in FIG. 13A shown closed position.

At the in FIGS. 13A to 13F As shown, the position of the projections 31 on the control element 30 relative to the longitudinal axis 50 is shown on the right side. The control member 30 is not slidably held along the longitudinal axis 50 on the rod 10 but rotatably supported, see FIGS. 7 to 12 , With each opening and closing of the drawer 1, the control 30 rotates, depending on the design of the control cam 33 by a maximum of 180 °. In the exemplary embodiment, the control rotates oscillating by about 120 °. If a plurality of projections 31 or only one projection 31 are provided on the control element 30, the angle of rotation and direction of rotation of the control element 30 can be modified accordingly. In addition, a rotation of the control element 30 is only possible in a rotational direction about the rod 10, so that the control element 30 is moved circumferentially in one or more closing cycles.

In the Figures 14A and 14B a second embodiment of an opening device is shown in which the latching mechanism is formed modified relative to the first embodiment, wherein the same components are denoted by the same reference numerals. In this locking mechanism, the position of the closed position can be adjusted. It is on the guide housing 6, a housing 11 'is provided, the two relatively adjustable sleeve-shaped housing parts 12' and 20 '. The housing part 20 'is fixedly connected to the guide housing 6, while the housing part 12' is adjustable by turning, as indicated by the arrows. In the closed position of the drawer 1, an end stop is formed from the insertion stop 36 on the latch 7 and the insertion stop 35 on the guide housing 6.

In the FIGS. 15A and 15B the function of adjusting the housing parts 20 'and 12' is shown. By rotating the sleeve-shaped housing part 12 ', the position of the sleeve-shaped housing part 12' shifts relative to the stationary housing part 20 '. As a result, the position of the rod 10 is adjusted to which the latch 7 and according to the drawer 1 is coupled.

How out FIG. 16 shows, the fixedly coupled to the guide housing 6 housing part 20 'has a threaded portion 29, whose external thread is in engagement with an internal thread on the housing part 21. The housing part 21 'is latched via one or more projections 23 with the sleeve-shaped housing part 12'. Furthermore, the outer housing part 13 with the sleeve-shaped housing part 12 'is locked.

The sleeve-shaped housing part 12 'has on the outer circumference a plurality of ribs 25', which serve to facilitate turning. When the sleeve-shaped housing part 12 'is rotated, the unit of sleeve-shaped housing part 12', outer housing part 13 and housing part 21 'moves relative to the fixed housing part 20'. On the housing part 21 ', the locking receptacle 40 is formed on a sleeve-shaped portion, on which the projections 31 of the annular control element 30 can be fixed. As a result, the position of the latching receptacle 40 relative to the guide housing 6 is adjusted when turning the sleeve-shaped housing part 12 ', which causes an adjustment of the drawer 1 relative to the surrounding furniture body accordingly. Thus, the gap between front panel and furniture body can be regulated. As a result, the gap can be adjusted so that a high reliability for the opening device is achieved.

The function of the opening device is otherwise formed as in the first embodiment, in particular, the annular control member 30 moves according to the described control curve.

In FIG. 17 is a sectional side view of the housing 11 is shown, wherein the engagement of the sleeve-shaped portions 14 and 21 in the sleeve-shaped housing part 12 are visible. As a result, a cylindrical guide is formed in the housing 11, which acts as a linear guide for the disk 27 on the rod 10. Furthermore, the annular control element 30 can also be rotated about the longitudinal axis 50 via the described control cam 33.

In the illustrated embodiments, the control cam 33 is formed by two housing parts 13 and 20 which act on the annular control element 30. It is then of course also possible to provide in the sleeve-shaped housing part 12 a recess which passes through the wall of the housing part completely or partially and then forms a control cam for one or more projections 31 of the control elements 30.
