Definitions

  • the invention generally relates to a releasable coupling for linear power transmission, in particular for drawer rails, according to the preamble of patent claim 1.
  • the invention relates to a damper which is releasably coupled to an opening and / or closing system, and in particular for furniture parts (drawers, doors, rotary, swivel and sliding doors, flaps ...) is provided.
  • Couplings for linear power transmission are well known in the art, for. B. on drawer rails as damper automatic retraction units from the DE 201 21 255 U1 , of the DE 203 18 929 U1 or the DE 102 56 133 B4 ,
  • the DE 201 21 255 U1 discloses a damper automatic retraction unit, wherein the linear damper and the automatic retraction are arranged in a common housing and the piston rod of the damper is integrally fixedly connected to the slide of the automatic retraction.
  • the DE 203 18 929 U1 discloses a damper automatic retraction unit, wherein the linear damper and the automatic retraction are also arranged in a common housing, but the piston rod of the damper and the catch member (slide) of the automatic retraction are formed as separate components, at least during the movement of the pawl member coupled together.
  • the piston rod end piece has a head part which is larger in relation to the outside diameter of the piston rod.
  • the DE 102 56 133 B4 discloses a linear damper, which is integrated in the drawer slide, wherein the piston rod of the damper is eccentrically guided in the cylinder.
  • Object of the present invention is a generic releasable coupling for linear power transmission, in particular for a combination between a Damper and a pull-in and / or pull-out automatic, to provide, which is easier, cheaper and more reliable in design, retrofitting and variability, as in the prior art.
  • At least one of the two components for radial force deflection by a radial offset, at least one radial displacement means which causes the releasable coupling for linear force transmission between the two components, and that the two components are constantly connected to each other via the releasable coupling are, wherein the radial displacement means is an integrally and cohesively connected to the displacement means L-, S- or Z-shaped bend or bend with purely radial or oblique or multi-stepped intermediate piece, or a two-part and non-positive or positive fit with the displacement means is connected eccentric block.
  • the advantage is that the two components to be detachably coupled can lie in different planes and have a radial offset with regard to the force input and output directions.
  • linear dampers automatic feeders and automatic pull-out, which are each arranged on the same rails of the rail system.
  • the damper linear damper, pneumatic or hydraulic
  • an opening and / or closing system eg automatic feed
  • a simple and good coupling and decoupling is ensured.
  • a "storage space optimization" of the overall system is achieved, so that the usable space in the drawer is not reduced, opposite Drawers without damper.
  • the damper according to the invention can be retrofitted (automatic intake also works without damper) and is interchangeable without major interventions such as disassembly of the entire guide.
  • the damper remains in a multi-functional part, which represents an extension of the drawer rail, and the automatic feed mechanism is fixed below the drawer rail.
  • the "functional level" of the two elements is offset, so that the parts of both elements which are displaceable and connected to each other are not displaceable on the same plane. Damper with a concentric piston rod are cheaper and have technical advantages over an eccentric piston rod, so that jamming and squeaking is avoided.
  • a touch-latch system could be used, i. that the push-pull of the touch-latch system could be equipped with a transversely compensating offset means.
  • the one and / or other element damper and / or automatic retraction or at least a part thereof (eg piston rod or spacer) is indirectly or directly equipped with an offset means, so that both elements can be connected and the displaceability of the parts can be smooth and trouble-free
  • the offset means may be formed integrally or not with this part or element.
  • the offset means may or may not have an elastically resilient and latching coupling device (in this case, the coupling device is on the other element).
  • the coupling device can thus be easily constructed so that the two elements can be coupled and decoupled well and safely (during assembly / disassembly, but remains in operation). It can be known per se: magnet, clamp, snap connection.
  • the shape of the bend can be adapted to the needs and e.g. be straight or oblique, S-shaped, Z-shaped or with steps, etc ..
  • the piston rod is preferably made of metal and preferably bent at its front free end, so provided with the bend.
  • Fig. 1 shows the body 2 (shown schematically) with a lower drawer 1 in the fully extended state with drawer slide 3 as a full extension, the upper drawer is removed and not shown.
  • Fig. 2 shows the drawer slide 3 in the extended state as a full extension with carcass rail 5, middle rail 6 and drawer rail 4, which are mounted to each other via conventional roller carriages or rollers longitudinally displaceable.
  • a multi-function part 7 at the front free end of the drawer rail 4 forms the extension of the drawer rail 4 and supports a damper 8, which is to slow down the retraction movement of the automatic retraction 11.
  • the multifunction part 7 is not necessarily necessary for the solution of the recording of the damper 8, which could alternatively be stored directly on the drawer rail 4.
  • the housing 15 of the automatic retraction mechanism 11 is mounted on the same rail as the damper 8, in this case the drawer rail 4. Both components, the damper 8 and the automatic retraction 11 but could alternatively be arranged on one of the other rails 4, 5.
  • the coupler 17 of the automatic intake 11 on the drawer rail 4 engages before the end of the closing process the stop / driver 18, which is located on the carcass rail 5, so that the drawer 1 automatically under the force of the spring 14, damped by the damper 8, pulled becomes.
  • the damper 8 therefore damps the end of the closing process.
  • Damper 8 and automatic retraction 11 are releasably connected by means of a piston rod 9 of the damper 8 and by means of a spacer 12 of the coupler 17 of the automatic retraction 11. Between damper 8 and automatic intake 11, a further component (not shown) may additionally be present.
  • Fig. 3 The piston rod 9 is centrally concentric, and not eccentric as in the prior art, arranged in the cylinder 19 of the damper 8 and guided there. However, the piston rod 9 of the damper 8 does not run on the same plane as the spacer 12 of the automatic retraction 11, but whose Lijnsmittenachsen have a radial offset 23, so that a radial force deflection of the power lines of the piston rod 9 and spring 14 (the spacer 12) to the radial offset 23 takes place. To connect the two parts 9 and 12, the end 10 of the piston rod 9 is angled or bent and engages e.g. in a recess 13 of the spacer 12 a.
  • Fig. 3a the coupling between damper 8 and automatic intake 11 is shown as an enlarged detail in the situation shortly before the end of the closing operation of the drawer 1, i. Damper 8 and automatic intake 11 are each half-retracted.
  • the damper 8 is here directly connected to the drawer rail 4, but may alternatively also be indirectly connected via the multi-function part 7 of Figures 2 and 3 with the drawer rail 4.
  • the housing 15 of the automatic retraction mechanism 11 is likewise connected directly to the drawer rail 4, but may also be indirectly connected to the drawer rail 4 via an intermediate component (not shown).
  • the free rear end of the piston rod 9 is connected to the spacer 12 of the automatic retraction 11, so that the bend or bend 10 of the piston rod 9 in the receptacle 13 of the spacer 12 superimposed.
  • This connection is therefore detachable, so that one of the elements 8 or 11 can be replaced, or both elements 8, 11. During operation of the drawer guide, the connection can not be solved, of course.
  • the receptacle 13 for the end 10 of the piston rod 9 can be designed arbitrarily.
  • the spring 14 hangs with its one end at the bottom of the housing 15 of the automatic feed 11, its other end hangs on the front end of the spacer 12.
  • the coupler 17 in the spacer 12 is rotatably mounted.
  • the coupler 17 engages in the stop 18 on the carcass rail 5, when the drawer guide comes to the end of the closing operation of the drawer 1 and the prestressed spring 14 (tension spring) relaxes and pulls in the feed direction 21 in the direction of the stopper 18 arresting coupler 17 together and takes the housing 15 of the automatic intake 11 with.
  • the housing 15 is displaced relative to the fixed spacer 12, since this is displaceably guided in the housing. Characterized in that the housing 15 of the automatic feed 11 is connected to the drawer rail 4, and this in turn with the drawer 1, the drawer 1 is retracted in the feed direction 21 in the furniture body 2.
  • the cylinder 19 of the damper 8 is on the piston when pulling the drawer rail 4 in the feed direction 21 20 of the damper 8, which is located at the other free end of the piston rod 9, pushed, whereby a damping of the retraction movement in the feed direction 21 of the drawer rail 4 and thus the drawer 1 takes place.
  • the damper therefore has conventional means (not shown) for braked slow displacement of the air (or fluid, e.g., oil) contained in the chamber portions of the cylinder 19.
  • the spring 14 After completion of the pulling of the drawer 1, the spring 14 is completely or partially relaxed, and the spacer 12 is in its extreme left (ie left in Fig. 3a) in its housing 15 and the piston 20 is also in its extreme left ( ie left in Fig. 3a) in its cylinder 19th
  • the pull-out of the drawer 1 in the withdrawal direction 22 is analogously reversed to the insertion process in the direction of insertion 21 as described above, with the difference that the damping function of the damper 8 is omitted. If the coupler 17 solves on the drawer rail 4 from the stop 18 on the carcass rail 5, then the spring 14 is again completely tense, as the spacer 12 in its extreme position right (ie right in Fig. 3a) in its housing 15 and the piston 20 is also in its extreme position right (ie right in Fig. 3a) in its cylinder 19.
  • Fig. 5 are two bends as an angled portion 10 b in the front free end of the piston rod 9 is present.
  • an additional part 16 is fixedly attached to the front free end of the piston rod 9, which can be detachably inserted with its pin 16a in the receptacle 13 of the automatic retraction 11.
  • FIG. 7 shows a part of a touch-latch system 26:
  • the ejector 24 is formed from outside like the damper 8 according to FIG. 3a with cylinder 19 and angled piston rod 9, 10, but inside the ejector 24 has a spring 25 between the bottom of the cylinder 19 and the piston 20.
  • the spring 14 of Figure 3a is omitted, ie, that the automatic retraction 11 loses its function and acts only as an extension element.
  • the angled piston rod 9, 10 is always connected during operation of the drawer with the spacer 12, but only temporarily with the stop 18, indirectly via the coupler 17.
  • Figure 3a combination damper automatic retraction
  • a touch-latch system 26 typically includes a pusher 24 and a latching system (not shown) wherein the latching system may be separate from pusher or integrated with the pusher.
