Definitions
- the invention relates to an automatic retraction mechanism for drawer pull-out guides with a guide rail to be fastened to a body wall of a piece of furniture and a guide rail — optionally with the interposition of a central rail — which is displaceably mounted relative to the guide rail and can be fastened to the drawer, one in one of the two aforementioned the outer rails arranged pawl housing is provided by a spring arrangement with an elongated coil spring bistable in two end positions spaced apart in the drawer movement direction movable pawl component, which has a receptacle for a driver provided on the other rail, which during the relative displacement of the rails when approaching the closed position, retracts into the receptacle and unlocks the pretensioned movable pawl component from " the assigned end position, whereby this under the action of the spring tension in the a The other end position is moved and, via the driver held in the receptacle, takes the rail assigned to it in the drawer-pulling direction.
- Drawer guides of this type provided with automatic retraction (DE 4 020 277 C2), which inevitably hold a drawer held in a cabinet body during the closing movement before reaching the fully closed position due to the tensioning force of a prestressed spring into the drawer closed position and against accidental occurrence Extending - for example, due to the reaction of the impact impact of the drawer panel on the cabinet body or due to air displacement inside the cabinet body when inserting or extending adjacent drawers - has become increasingly common in recent years.
- automatic retraction DE 4 020 277 C2
- the pretensioning springs used for pulling in must be dimensioned in such a way that the associated drawers are securely retracted even with heavy weight loads and, on the other hand, less weighted drawers are not opened unintentionally even with air currents in the body. It has now been shown that it is difficult here to optimally design the prestressing of the spring, which takes all requirements into account. As a rule, the tension force of the spring is therefore measured on the safe side, which means that at least lighter drawers are accelerated on the feed path and strike the body if they are not deliberately slowed down by the person operating the drawer.
- the invention has for its object to develop the known automatic feeders so that when opening a drawer equipped with them, no rapidly increasing closing force has to be overcome.
- this object is achieved according to the invention in that the elongated one, which is fixed at one end in the latch housing.
- Coil spring is initially arranged essentially parallel to the direction of displacement of the running rail in the latch housing and is then guided around a deflection device, and that the end of the spring not fixed in the latch housing is then returned to the movable latch component and is fastened to it.
- the deflection of the spring practically doubles its length, with the result that the increase in the pull-out resistance of the drawer is halved from its completely closed state until the latch component is locked and the associated rail is then uncoupled.
- a damping device which brakes the movement of the unlocked pawl component relative to the pawl housing can then also be provided.
- the deflection device of the automatic feed mechanism is designed as an arcuate sliding guide made of low-friction material.
- the sliding guide can then be a separate component with an arcuate guideway for the elongated helical spring, the separate component being fastened to the latch housing.
- the sliding guide can also be an integral part of the latch housing itself, which is provided with the arcuate guideway.
- the deflecting device can also be formed by at least one deflecting roller which is rotatably arranged in an end region of the latch housing and over which the elongated coil spring is or are guided. This prevents friction between the coil spring and the deflection device.
- the deflecting roller (s) is or are in turn provided in their circumferential surface with a guideway which is appropriately arched in cross section.
- the configuration can be such that the deflection roller (s) is or are rotatably mounted on the associated end region of the latch housing.
- the idler roller (s) can also be rotatably mounted on a separate fastening plate which can be fastened directly or indirectly to an associated rail of a drawer pull-out guide on the latch housing.
- the bias of the coil spring can be changed by changing the position of the separate mounting plate with respect to the pawl housing.
- the spaced-apart deflecting rollers are then expediently arranged in a deflecting roller housing projecting laterally from the latch housing, this deflecting roller housing advantageously being connected to the handle housing to form an integral unit.
- the damping device can also be functionally connected to the deflection roller.
- the damping device is then preferably formed by a rotary damper, the axis of rotation of which coincides with the axis of rotation of the deflection roller.
- rotary dampers are known per se and can be ordered from the relevant manufacturers according to the catalog.
- the rotary damper can then be assembled with the deflection roller.
- the rotary damper can also be integrated into the roller.
- Figure 1 is a side view of a first embodiment of an automatic feeder according to the invention in the end position assigned to a closed drawer.
- Fig. 2 is a side view of a second embodiment of the automatic feeder.
- 3 to 5 are a side view, a plan view and an isometric view of a third embodiment of the automatic feeder.
- FIG. 1 of an automatic pull-in mechanism according to the invention designated in its entirety by 10, has an elongated flat latch housing 12 in which a flat, disk-like latch component 14 is displaceably guided between two end positions.
- This guidance takes place through the engagement of two guide pins 16, 18, which protrude from the flat part of the pawl component 14 and are spaced apart from one another in the direction of displacement and which, in the manner of a link guide, are provided in a guide groove provided in the associated wall of the link housing 12 and extending linearly over most of their longitudinal extent 20 intervene. Only in the right end section in FIG.
- the pawl component 14 is provided on its upper edge with two projections 22, 24, which protrude from the edge of the pawl housing and are spaced apart from one another, between which a receptacle 26 is formed for a driver 28 which is only shown in broken lines in the drawing and which is formed by one when the drawer is pulled out
- Component of the pull-out guide protrudes relative to the pawl housing in the pull-out direction and inevitably shifts the pawl component 14 in the pawl housing 12.
- the pawl component 14 is thus taken to the right by the driver 28 from the position shown in FIG.
- the end position of the pawl component When the end position of the pawl component is reached, it is tilted, as mentioned, so that the front projection 24 in the pull-out direction is guided downwards into the interior of the pawl housing and by the tensioning force of the tension spring designed as an elongated coil spring 30 is locked in this tilted position.
- the driver 28 can then emerge from the receptacle 26 and thus the slide rail holding the drawer can be displaced on the guide rail largely without force.
- a damping device 32 is provided in an elongated recess, which is designed as a piston damper, in which a piston is mounted in an elongated cylindrical damper housing 34, the piston rod 36 of which extends out of the housing 34 and engages on the pawl component 14.
- One end of the elongated coil spring 30 is fastened above the cylindrical housing 34 of the damping device 32 in the pawl housing 12 and then ün housing to the left to a deflection plate 38 fastened to the left end of the housing with an arcuate recessed guideway 40 and in this guideway 40 back into the housing 12 and up to the pawl component 14, where the second end of the coil spring 30 is attached.
- the exemplary embodiment of the automatic feed system according to the invention shown in FIG. 10, designated 10 ', differs from the automatic feed system 10 described in connection with FIG. 1 only by the deflection device for the elongated coil spring, so that it is sufficient to describe the modified configuration below, while otherwise, to avoid repetition, reference can be made to the preceding description of the automatic feeder 10.
- a separate disc-shaped and rice-limited deflection roller 38 ' is used as the deflection device in the automatic feeder 10'.
- det which is rotatably mounted on a bearing pin 44 protruding from a separate mounting plate 42.
- This mounting plate can either be connected to the latch housing 12, or it can also be fastened directly or indirectly to one of the rails of the drawer pull-out guide, for example the fastening flange of the guide rail, by means of separate fastening screws 46.
- the pretension of the helical spring 30 can be changed by changing the distance between the pawl housing 12 and the fastening plate 42.
- the use of the deflection roller 38 ' also makes it possible to brake the damping of the movement of the pawl component 14 relative to the pawl housing 12 by using a rotary damper connected to the deflection roller 38'.
- rotary dampers are known per se and can be obtained from their manufacturers with the desired damping effect.
- the rotary dampers can then be connected, for example, to the deflection roller 38 ′ and supported on the fastening plate 42.
- An integration of the rotary damper into the deflection roller 38 ' is also conceivable.
- FIGS. 3 to 5 show, as a third exemplary embodiment, an automatic feeder 10 ′′ which basically corresponds functionally to the automatic feeders 10, 10 ′ described above, so that only the modifications made to these automatic feeders are described below, while it is sufficient with regard to the corresponding structure, to refer to the preceding description, especially since functionally identical components are assigned the same reference numerals in the various examples in the drawing figures.
- the essential modification to the automatic retraction system 10 ' is that the deflecting device instead of a deflecting roller 38' has two deflecting rollers 38 "which are spaced apart in the longitudinal direction and which are rotatably mounted on the base plate of a deflecting roller housing 48 which is laterally integrally attached to the pawl housing 12
- Spring 30 is - according to the automatic feeder 10 '- first by 180 ° around the circumference of the rear first guide roller 38 "of larger diameter around and then in the opposite direction to the front guide roller 38" of smaller diameter by 180 ° and in the guide roller housing 48 back to returned in the immediate vicinity of the first deflection roller 38 "of larger diameter.
- the free end of the spring 30 is then attached to a suitable, from the bottom of the deflection roller housing 48 protruding bracket attached. Due to the double deflection of the spring 30 into a total of three partial strands, a spring of a correspondingly greater overall length can be used, which - based on the same extension path of the latch component 14 - is tensioned to a lesser extent when a drawer is moved.
- the change in the preload of the spring 30 on the displacement of the pawl component 14 from one end position to the other is therefore less in relation to the initial preload. This allows the preload of the spring to be reduced, which results in a correspondingly lower pull-out resistance of the pull-out guide provided with the automatic retraction mechanism according to the invention and thus in a drawer supported on such a pull-out guide.
