Description

Piece of furniture

The present invention relates to a piece of furniture according to the preamble of claim 1.

From document EP 1 845 821B, a closing and opening device for drawers is known, in which an interlocking mechanism is provided for holding the drawer in a closed position. The interlocking mechanism comprises a prestressed lever through a spring, which is movable along a cam curve. The lever can be held in a locked position from which it is compressed, when opening the drawer, against an impulse slope, in order to then be moved along the cam curve. In this interlocking mechanism it is harmful that the modifications of the groove between the front panel of the drawer and the furniture, conditioned by the tolerances, cannot be compensated. In addition, in wide drawers it can happen that a biased introduction of the drawer, which unlocks one side of the locking mechanism, and on the other side still does not cause any unlocking. In addition, in the case of a strong introduction, the lever may trip over one end of the cam curve and be damaged.

The document DE 101 62 573 publishes a Touch-Latch hardware for locking a movable piece of furniture. For this, two mounting hardware are arranged on a frame, on which rotating levers are supported. The levers are joined together by a rod, which is provided, by means of a guide hardware, with a curved guide, in which a bolt is guided. Through the movement of the bolt and the rod, a piece of furniture can be locked.

Hence, the objective of the present invention is to achieve a piece of furniture with an interlocking mechanism that allows a compensation of the tolerances when assembling a drawer, and also that guarantees a safe opening also in the case of wide drawers.

This objective is achieved with a piece of furniture with an interlocking mechanism with the characteristics of claim 1.

According to the invention, an exit area for the tracer, in which the tracer is movable away from the housing, has been configured in the cam curve, on the pulse slope and adjacent to the housing for the interlocking position that the creeper can move as far as possible into the exit zone, without encountering an end of the cam curve. Through this a compensation of the tolerances can take place through the exit zone, both in the assembly of an extraction guide in a body of a piece of furniture, as well as in the case of a relative displacement of the position of the panel frontal with respect to the body of the furniture, since the drag can be introduced in the exit zone with almost no end stop. In addition, in the case of especially wide drawers, the movement of the drag on the opposite sides may also be different, so that a necessary introduction of the drag into the exit zone, beyond the interlocking, is also possible.

Preferably, the exit zone, at least one, comprises a section of the channel in which the carrier is movable from one side to the other. Through this, a lateral displacement of the drive in the exit zone can be avoided, so that the exit zone is effective in the direction of introduction.

In one configuration of the invention, two output zones are spaced apart from each other in the cam curve, one exit zone being effective before the insertion position and one exit zone after the insertion position. Through this, a certain biased position can be compensated for both opening and closing.

Preferably, the exit zone widens in a direction separate from the insertion position. Through this, a recess can be configured in the area of the exit zone, in which the dirt accumulates, due for example to abrasion in the movement of the drag on the cam curve.

According to the invention, a piece of furniture is also made available in which a drawer is movably housed in a body of a piece of furniture, an extraction guide with an insertion mechanism according to the invention being provided on opposite sides. Preferably, the length of the exit zones in the two locking mechanisms is here greater than the distance of a front panel of the drawer from the cabinet body, in the closed position. Preferably, in all the exit zones the distance between the housing of the insertion position and the end of the exit zone is greater than the distance from the front panel of the drawer to the cabinet body.

The invention is described in more detail below by means of several exemplary embodiments, with reference to the attached drawings. Shows:

An extraction guide 1 comprises a guide rail 2, which can be fixed to the body of a piece of furniture, and in which a sliding rail 3 is movably housed. In order to achieve a complete extraction, between the guide rail 2 and the travel rail 3 can be placed at least one intermediate rail 28. On the travel rail 3 an activator 4 has been fastened, which fits into a housing in a drag 5. The drag 5 is slidably housed in a travel guide 6 with a bent end section, the travel guide 6 being formed on a housing 7 that is fixedly connected with the guide rail 2. A spring element 8 has been placed on the housing 7.

As can be seen in Figures 2A and 2B, a rod 9 is provided in a spring housing 8 of the spring element, which is coupled with the drive 5 in a final section 10. The rod 9 is provided with a disk 11 in the opposite side, on which a pressure spring 12 is supported. The opposite end of the pressure spring 12 is supported on a cover 13, which is fixed on the spring housing 8. The housing 8 of the spring can be fixed with retention on a sleeve 14 of the housing 7.

A drag 16, which is formed by a wire with a bent end section 17, has also been fastened on the carrier 5. The drag 16 fits into a construction piece 20 with a cam curve, which is held in the housing 7 on a fixing section 19. The construction piece 20 is held on the housing 7 in a housing 18, the drag 16 being housed movable between the construction piece 20 and the housing 18.

A modified embodiment of an insertion mechanism on an extraction guide 1 is shown in Figure 3, in which a compact housing 7 'is provided, in which a drag 5' is guided. In this case, the spring element comprises a spring housing 8 ', in whose lower part a housing 18' is configured, which is coupled with the construction piece 20. Between the construction piece 20 and the housing 18 'the housing is housed. mobile 16, which is movable with the 5 'on a coupling element 15.

The construction piece 20 configures a cam curve 21 for the drag 16, as will be shown in Figures 4A and 4B. The cam curve 21 is configured in a loop-shaped area, and has a final section 23 of a single rail in the opening direction. Furthermore, in the cam curve 21, a trough-shaped housing 22 has been configured for the drag 16, in which the drag 16 can be fixed by engaging the force of the pressure spring 12.

As can be seen from Figures 5A and 5B, adjacent to the housing 22 there is an impulse slope 29, against which the final section 17 of the drag 16 is compressed when the locking mechanism is to be unlocked. Then, the drag 16 travels along the pulse slope 29, in a channel-shaped exit zone 24, and then moves on the cam curve by the force of the spring 12.

In figure 5A the construction piece 20 is shown in detail shortly before the engagement of the drag 16 in the closed position. Then, the final section 17 is in a second exit zone 25, which is located in front of the housing 22. In Figure 5B it is shown in detail that an elastic retaining ratchet 27 has been placed on the cam curve 21 , whose free end is positioned on the cam curve 21, and in the resting position it reaches the exit zone 25, which has a widened end area. In the area of the retention ratchet 27, the drag 16 is laterally displaced to such an extent that it slides in a movement in the housing 22 by the spring 12, and engages there after a certain lateral displacement, and

it then rests in front of the 29 slope of momentum.

An area of the cam curve 21 in the area of the housing 22 is shown in detail in Figure 6A, two elongated exit zones 25 'and 24 being configured, in the form of a channel. The exit zone 25 'is configured with a greater length than the exit zone 24, and in this final section the dirt 30 can be accumulated, which originates through abrasion in the movement of the drag 16 along the cam curve 21, or through other sources.

An exit zone 25 is shown in detail in Figure 6B, which widens and thus configures a recess in which dirt 30 can accumulate.

Figure 6C shows in detail two zones 25 'and 24' spaced apart from each other, which have the same length, and in this sense form a final U-shaped section of the cam curve 21, in which it is configured centrally the slope 29 of impulse.

Figure 6D shows in detail an embodiment of two outlet zones 24 '' and 25 '', which are joined together, so that in a final U-shaped section dirt 30 can accumulate. here the volume of the exit zone is greater than that necessary for the guide of displacement of the conveyor 16, so that impurities can be stored in that zone. According to the invention, the junction zone is not covered by the final section 17, since then the resting position cannot be reached. If, however, the junction area has to be traversed through the final section 17, the insertion function can be activated again by a new pressure on the front panel of a drawer in the closing direction.

Figures 7A to 7D show a piece of furniture in which the locking mechanism according to the invention is used. The furniture comprises a body 40 of the furniture on which at least one front panel 41 for a drawer is housed in a movable way. An extraction guide 1 can be mounted correspondingly on opposite sides of the furniture body 40.

In order to open the drawer, the front panel 41 of a drawer is pressed against the body 40 of the furniture, in the closing direction. In this, a position corresponding to Fig. 7B can be reached through a lateral effort, in which the front panel 41 already rests on one side on the body 40 of the furniture, and on the opposite side a distance L between the body 40 of the furniture and the front 41 of the drawer (figure 7C).

In the area of the construction piece 20 and the cam curve 21, the position of the drag 16 is such that, according to Figure 8A on the left side, that is, where there is a distance L between the body 40 of the furniture and the front 41 of the drawer, the drag 16 was displaced only minimally outside the housing 22, and was displaced laterally, by means of the support on the impulse slope 29, but is displaced at least minimally within the exit zone 24. On the side opposite, the drag 16 has moved considerably, on the contrary, within the exit zone 24, since there the front panel 41 rests on the body 40 of the furniture. However, this unequal movement of the front panel 41 in relation to the body 40 of the furniture is not harmful for the disengagement of the two locking mechanisms, since at least on both sides such movement of the corresponding drag 16 was achieved, that this It was moved out of the respective housing 22.

Figures 9A to 9D show a body 40 of a piece of furniture with a front panel 41 during the closing process. Here too, by way of example, there is a distance L on the left side of the body 40 of the furniture between the body 40 of the furniture and the front panel 41. This acts on the locking mechanism in the manner shown in Figures 10A and 10B. On the right side, the front panel 41 rests on the body 40 of the furniture, so that, according to FIG. 10B, the drag 16 was almost completely displaced within the exit zone 25 ', and thus an insert is guaranteed Sure in the next step.

On the opposite side there is, according to fugures 19A and 9C, a distance L between the front panel 41 and the body 40 of the furniture. However, the drag 16 was displaced through the cam curve to such an extent that the retention ratchet 27 was exceeded, and thereby the drag 16 is positioned in front of the exit zone 25 ’. If the front panel of the drawer is now released, both the drag 16 on the left side and the drag 16 on the right side slide into the respective housing 22 provided for them in the construction piece 20.

In the preceding exemplary embodiments, the locking mechanism for an extraction guide was described. Naturally, it is also possible to provide such a locking mechanism in the case of doors, hatches or other folding construction parts. In addition, the type of locking mechanism can be configured with a spring element and other construction parts other than those described.
