Description

  The present invention includes an elastically urged travelable carriage on which a furniture part can be releasably connected and a separation drive body is tiltably supported thereon, and a fluid buffering device for buffering a retracting movement of the carriage. It relates to a closing device and / or a retracting device for movable furniture parts.

Such a closing device and / or a retracting device for use in a drawer is known, for example, from US Pat. Here, the drawer which can travel freely over the most part of the drawer range is gripped by the driver of the retracting device in the rear pull-in range and reliably pulled to the rear end position, ie closed. Due to the shock absorber integrated in the retracting device, the last part of the closing movement is buffered and a quiet closing process is achieved without any closing noise.
European Patent Publication No. 1120066

  The object of the present invention is to improve this kind of closure device and retraction device by making the fluid damping device effective exclusively in the case of a push-in movement of the drawer.

  The problem according to the present invention is solved by having a stop body in which the fluid shock absorber is separated from the travelable carriage and the carriage hits the opposing stop body during the retraction movement.

The fluid shock absorber includes a cylinder and a piston that can travel linearly in the cylinder,
The stop is conveniently provided to be formed from the free end of a piston rod protruding from the cylinder.

  With the arrangement according to the invention, the piston is rapidly moved upon opening of the drawer, thus preventing air from being pushed into the cylinder. Furthermore, the drawer pulling movement is not braked.

  In another embodiment of the invention, the stop is provided such that it is formed by the free end of the driver pin that activates the rotary shock absorber during the retracting movement of the carriage.

The closing device and / or the retracting device according to the present invention is more convenient as a retracting device for the drawer, but can also be used as a door closing device. Also, in the latter case, the door can swing freely over most of the opening stroke, and when the door is in the closing process, it will be grasped by the closing device only when it comes close to its closed state and will be securely closed. .
Next, two embodiments of the present invention will be described with reference to the accompanying drawings.

  In the illustrated embodiment, the closing device and / or the retracting device 1 is supported by the support rail 2 of the drawer guide set. The support rail 2 is attached to the side wall of the house in a conventional manner. A lock portion having a driving body pin 6 protruding downward is attached to the rear end of the insertion-side drawer rail 3.

  The closing device and / or the retracting device 1 has a housing 7 fixed on the horizontal bar of the support rail 2.

  Inside the housing 7, a carriage 8 on which the drive body 12 is tiltably supported is arranged so as to be able to travel linearly. The driving body 12 is supported by the carriage 8 via pins 13 and has a protrusion 24 that is guided in the guide path of the housing 7.

  Two elastic bodies 14 are fixed to the fixed portion 15 and engaged with the carriage 8. The elastic body 14 is configured as a tension spring. The fixing part 15 is separated from the housing 7 in the assembly position, but is a supplementary part of the housing 7. The distance from the housing 7 to the fixed portion 15 determines the tension of the elastic body 14.

  2 to 5, the closing device and / or the retracting device 1 according to the present invention is in a ready state. When the drawer is closed and the drawer rail 3 is moved rearward, the driving body pin 6 fits into the notch 16 of the driving body 12, and the driving body 12 starts to rotate from the locked state shown in FIG. As soon as the protrusion 4 of the drive body 12 is in the guide path of the housing 7, the elastic body 14 pulls the carriage 8 with the drive body 12 backwards, so that the drawer is brought into a fully retracted state. In the illustrated embodiment, the closing device and / or the retracting device 1 are arranged on the fixed support rail 2 and the driver pin 6 is arranged on the insertion side extraction rail 3. The reverse arrangement, i.e. the arrangement of the closing device and / or the retracting device 1 on the drawer rail 3 and the arrangement of the driver pin 6 on the support rail 2 may also be possible.

  Furthermore, a fluid damping device 9 is provided which can be configured directly in the housing 7 or arranged side by side with the housing 7 in the illustrated embodiment.

  In the embodiment of FIGS. 1 to 6, the fluid shock absorber 9 includes a cylinder 10 and a piston rod 11, and is configured as a linear shock absorber including a piston that can run in the cylinder. The free end of the piston rod 11 serves as a stop for the carriage 8. The carriage 8 serves as an opposing stop body and has a protrusion 17 projecting sideways. It is essential for the invention that the piston rod 11 is not pivoted by the carriage 8 but hits the carriage 8 or the protrusion 17 of the carriage 8 only during buffering. When the carriage 8 is in the preparatory position with the driving body 12 in the initial position, the free end of the piston rod 11 has previously hit the projection 17 or is at a slight distance from the projection.

  In the case of the opening of the drawer, that is, when the carriage 8 is moved forward together with the driving body 12, it is essential that the piston rod 11 is not pulled together with the carriage 8. The protrusion 17 of the carriage 8 moves from the free end of the piston rod 11 and the piston of the shock absorber is moved into the ready state again at a substantially lower speed than the carriage 8, for example by a spring in the cylinder 10. . In this way, air is prevented from entering the cylinder 10 and this is particularly important if the buffer fluid is, for example, oil.

  In the embodiment according to FIG. 7, the fluid shock absorber is configured as a rotary shock absorber 20 with a pinion 18 that meshes with the rack 19. The rack 19 serves in this embodiment as a drive rod for the rotary shock absorber 20, and thus replaces the piston rod 11 of the previous embodiment. The free end of the rack 19 further abuts against the opposing stop body of the carriage 8 formed by the protruding portion 17 when buffering.

  When the drawer is opened, the projecting portion 17 moves from the free end of the rack 19, and the rotation shock absorber 20 is not biased by the carriage 8 when the drawer is opened. In the ready state, a spring 21 is provided that moves the rack 19 independently of the movement of the carriage 8 and the driving body 12.

1 schematically shows a drawing of a drawer guide set with a closing device and a retracting device according to the invention. Fig. 2 shows a development view of a part of a closure device and a retracting device according to the invention. Fig. 2 shows a plan view of a closing device and a retracting device according to the invention in the ready state. Fig. 2 shows a view from below of a closing device and a retracting device according to the invention in a ready state. Fig. 5 shows a view of the closure device and retraction device according to Figs. Fig. 2 shows a plan view of a closing device and a retracting device according to the invention at the end of the buffer stroke. Fig. 4 shows a plan view of another embodiment of the closing device and the retracting device according to the invention in the ready state.
