Description

The present invention relates to a feeder device for moving a drawer or for moving a rail of a drawer extension guide in the closed end position relative to a furniture body, with a Ausricht having housing, which serves to mount the feeder horizontally to a furniture body, wherein in or on the housing a spring-loaded carrier for applying force to the drawer or the rail of the drawer extension is at least partially movably mounted along a linear travel, wherein the driver with the drawer or with the rail of the drawer extension is releasably coupled.

Furthermore, the invention relates to a piece of furniture with at least one drawer, which can be pulled over a collection device of the type to be described in a closed end position.

Feeding devices for drawing a drawer in the closed end position have long been known, for example from the EP 0 391 221 B1 the applicant or from the GB 2 297 578 A , When Schubladenausziehführungen, which do not have their own collection device, there is often the desire to retrofit them with an additional locking device, the retraction movement can also be particularly attenuated. There are so-called roller thrust guides, in which a closure by gravity is brought about. This is made possible by a carcass rail, which has a rear sloping inlet bevel in the rear end. If the drawer is closed, it moves towards the end of the closing movement by the intended inlet slope by itself in the closed end position. If now the drawer is to be pulled into the closed position via an additional retraction device, the presence of the rear inlet slope can bring about an undesired decoupling or a jamming between the spring-loaded driver and a coupling element, which can be releasably coupled to the driver. In order to prevent such unwanted decoupling or jamming, in practice, the housing to be additionally mounted to the feeder with a slight inclination mounted on the furniture body, namely to the effect that the linear Traversing of the driver with its inner end of the body occupies a lower position than the front end of the body of the driver, so as to compensate for the inlet slope of the drawer extension guide. Such an oblique mounting of the collection device on the furniture body is relatively complex to perform and also requires a manual routine of the assembly staff.

Object of the present invention is to simplify the intended installation of such a retraction device on the furniture, wherein the retraction device is used in particular in connection with an inlet bevel having Schubladenausziehführung.

This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

According to the invention, it is thus provided that the linear travel path of the driver runs obliquely to the alignment of the housing.

The Ausregel of the housing can be formed by a side edge of the housing, which is substantially horizontal in the assembled state of a furniture. In a substantially rectangular housing, the linear travel of the driver can be arranged obliquely to a longitudinal axis of the housing.

In other words, the housing or its Ausrichtlinie can be mounted with horizontal orientation on the furniture body, in particular, provided for this purpose hole pattern can be used. By such arranged on the furniture body hole grid the fitter are given various predetermined attachment points available, whereby the housing can be easily attached to the furniture body with horizontal orientation. The travel of the driver runs obliquely to the alignment rule, so that in this way the inlet slope of the drawer extension is compensated.

In one embodiment of the invention can be provided that the driver between a parking position in which the spring is tensioned, and a End position, in which the spring is at least partially relaxed, is movably mounted along the linear travel, wherein the end position relative to the parking position is lowered in the assembled state of the collection device to a piece of furniture and the Ausrichtlinie of the housing is horizontal.

In a possible embodiment of the invention can be provided that the linear travel of the driver relative to the Ausrichtlinie of the housing between 2 ° and 8 °, preferably between 2 ° and 4 °, is inclined.

In addition, it can be provided that a damping device is provided, through which a movement of the driver is damped. The use of rotary and / or linear dampers with a displaceable piston in the cylinder has already proven itself here. According to one embodiment of the invention can be provided that the damping device has a - preferably hydraulic - cylinder-piston unit.

The furniture according to the invention is characterized by a collection device of the type described. In this case, it may be provided that a drawer pull-out guide is mounted on the furniture carcass, which has a drawer rail to be fastened to the furniture body and at least one drawer rail displaceably mounted thereto, wherein the carcass rail has an inlet bevel in the rear end area for the automatic retraction of the drawer into the closed end position, and wherein the linear travel of the driver of the retraction device is substantially parallel to the inlet slope of the carcass rail.

Fig. 1a shows a perspective view of a piece of furniture 1 with a furniture body 2, wherein drawers 3 are movably mounted on Schubladenausziehführungen 4 relative to the furniture body 2. The drawer pull-out guide 4 has a cabinet rail 5 to be fastened to the furniture body 2 and at least one drawer rail 6, which at the same time also forms the side wall of the drawer 3. The carcass rail 5 may have a C-shaped cross-section, wherein a roller 7 fixedly mounted on the drawer rail 6 can run along the C-profile of the carcass rail 5.

Fig. 1b shows the furniture 1 Fig. 1a with removed drawers 3. For each drawer 3 a cabinet rail 5 is to be fixed on each side of the furniture body 2. The carcass rail 5 has in the front end region to a stationary mounted roller 8, on which the drawer rail 6 can run. For retracting the drawer 3 in the fully closed end position, a collection device 9 is attached to the furniture body 2, which is to be described in more detail in the following figures. The feeder 9 detects the drawer 3 towards the end of the closing movement, whereupon the drawer 3 is pulled by the action of a spring of the feeder 9 in the full closed position.

Fig. 2 shows the furniture body 2 to be fastened to the carcass rail 5, which carries a roller 8 at the front end region. In the rear end region, the carcass rail 5 in the depth direction of the furniture 1 obliquely downwardly extending inlet bevel 10, through which the drawer rail 6 (and thus the drawer 3) can run by gravity into the full closed position. For additional movement support of the drawer 3 in the closed end position a separate feed device 9 with a spring-loaded driver 11 is present, which detects a to the drawer 3 or to be fixed to the drawer rail 6 coupling element 14, whereupon coupled to the driver 11 coupling element 14 (and thus the drawer 3) by spring force in the Furniture carcass 2 is fed. Due to the inlet slope 10 of the carcass rail 5, however, the rear end portion of the drawer rail 6 is lowered slightly in the closed position, which may lead to an undesirable jamming or unwanted decoupling between the driver 11 and the coupling member 14. The housing 9a of the intake device 9 has a linear travel path 12 for the driver. An angled section 13 adjoins the linear travel path 12, as a result of which the driver 11 can be guided into a parking position secured in force and / or at least partially in a form-fitting manner. The coupling element 14 to be coupled with the carrier 11 extends substantially horizontally in the mounting position.

Fig. 3a shows the attached to the furniture body 2 carcass rail 5 in a side view, which has the sloping downwardly sloping inlet bevel 10 in the rear end. The housing 9a of the intake device 9 is fixed to the furniture body 2 with a horizontal orientation. The housing 9a of the intake device 9 has an alignment rule A, which extends substantially horizontally in the mounting position. It can be seen that the linear travel path 12 of the driver 11 extends obliquely to the alignment rule A of the housing 9a, in particular in the depth direction of the furniture body 2 is arranged sloping into it. In one possible embodiment, the linear travel path 12 of the carrier 11 runs essentially parallel to the sloping inlet bevel 10 of the carcass rail 5, so that the coupling element 14 (FIG. Fig. 2 ) relative to the driver 11 over the entire travel of the drawer 3 can occupy the same height distance. Fig. 3b shows the in Fig. 3a marked area in an enlarged view. It can be seen that the longitudinal direction of the carcass rail 5 is essentially parallel relative to the alignment line A of the housing 9a of the intake device 9. The housing 9a can therefore be easily attached to the furniture body 2 via standard provided rows of holes.

Fig. 4 shows an exploded view of the collection device 9 with the housing 9a, on or in which a linear travel path 12 with the adjoining angled portion 13 is arranged or formed. The driver 11 can be pulled by the action of the spring 15 in a rear end position. To damp this retraction movement, a damping device 16 in the form of a cylinder-piston unit 17, 18 is provided, through which the last closing path of the drawer 3 can run attenuated. The piston rod 18 may be connected via a coupling part 11 a with the driver 11 - in particular articulated. For attachment of the housing 9a left and right attachment points 19a and 19b are present. The two attachment points 19a and 19b can be pushed by rotation by 180 ° on the guides 20 of the housing 9a. Depending on the position of the attachment points 19a and 19b, the housing 9a of identical design can optionally be fastened on the left and on the right side of the furniture body 2, wherein the flat sides of the attachment points 19a and 19b rest flat against the furniture body 2.

Fig. 5 shows a perspective view of the intake device 9 with the driver 11 in a biased parking position.

Fig. 6a and Fig. 6b each show the housing 9a of the feeder 9, wherein in Fig. 6a the attachment points 19a and 19b are arranged such that an assembly on the right side of the furniture body 2 is possible. In Fig. 6b however, the attachment points 19a and 19b occupy a position so that the housing 9a can be fixed on the left side of the furniture body 2.
