Definitions

  • the present invention relates to a retraction and damping device for a pull-out on both sides pull-out element, in particular drawer, in a freestanding body, which is slidably mounted in the direction of withdrawal in linear guides, and which is equipped at the front end portions each with a cover with detachable Locking means are provided, by means of which the covers are respectively lockable on the pull-out end side of the pull-out or on the body, see, for example DE 20 312 325 U1 ,
  • the object of the present invention is thus to provide a retracting and damping device for a pull-out element which can be pulled out on both sides, which retracts and damps an extension element inserted from both sides into the closed position.
  • the solution of this object is achieved in that the retraction and damping device has a sliding transverse to the pull-out of the pull-out sliding part with a cam which is fixed to the body and spring means in a closed position can be pulled, and the cam interacts with curves on the Pull-out are attached, and which have in the closed position of the pull-out a recess, in which the cam on the sliding part in the closed position of the pull-out element is pressed by the spring means.
  • the curve has a first curved path on both sides, along which the cam of the sliding part runs when the pull-out element pushes into the carcass.
  • a pivotable tongue closing off the unused curved path is provided between first curved paths running away from the indentation on both sides.
  • this tongue is avoided that when running the cam on the corresponding curved path lifting this cam can enter from the web.
  • a further advantageous embodiment of the invention is that of the indentation, the curve on both sides has a second curved path along which the cam of the sliding part when pulling out the Ausziehimplantations extends from the body, which has a lower slope of the indentation than the first curved path, and which second curved path again opens into the first curved path. Due to the lower slope of this web is achieved that the tensioning of the spring means of the retraction and damping device with less force is possible.
  • third cam tracks are attached to the outer region facing away from the indentation of the curve, which have a sloping shape towards the respective pull-out side of the pull-out element.
  • the sliding part cooperates with a locking arrangement, by means of which the sliding part with the cam in the closed position opposite the closed position can be locked.
  • the locking arrangement is provided with a pivotable from a locked position to an unlocked position latch which is controllable via a further curve path provided on the curve. This gives a simple structure of this arrangement.
  • the sliding part is equipped with a cooperating with the spring means damping element, whereby an optimal operation is achieved.
  • the spring means are mounted on both sides of the sliding part tension springs, and the damping element is a piston-cylinder unit, which is mounted between the two tension springs. This gives you optimal functionality.
  • a further advantageous embodiment of the invention is that the curve consists of a plate, preferably of plastic, and that the cam tracks are milled into the plate tracks. This results in a simple method of production.
  • the cam is designed as a roller rotatably mounted on an axis. This role can be unrolled on the tracks with little friction.
  • Fig. 1 is shown in a spatial representation of the pull-out 1 (with dash-dotted lines), which has the shape of a drawer.
  • This drawer is extendable along linear guides 2 in the direction of the double arrow 3 on both sides of a body, not shown.
  • one part 4 of the linear guide 2 is attached to the drawer 1, while the other part 5 of the linear guide 2 is fixed to the body, not shown.
  • This other part 5 of the linear guide has an angle section 6.
  • the locking device 7 is shown, with which the rear cover, not shown, can be locked to the drawer 1.
  • these locking devices 7 cause the cover on the extendable side is connected to the drawer, while the opposite cover is connected to the body.
  • the locking devices ensure that the cover which is in each case located on the pull-out side of the drawer is locked to the drawer, while the opposite cover is locked to the carcass.
  • a rail 8 is fixed, in which the sliding part 9 is slidably mounted.
  • the direction of displacement of this sliding part 9, represented by the double arrow 10, is perpendicular to the pull-out direction of the drawer and consequently to the double arrow 3.
  • the sliding part 9 is equipped with a cam 11.
  • a plate 13 is fixed, which is provided with a plurality of curved paths, as will be described in detail later.
  • this plate 13 which consists of plastic, the curves are milled from the bottom seen, the plate then rests with the flat side on the bottom of the bottom 12 of the drawer.
  • the curves already exhibiting molded plastic could be made and used.
  • the sliding part 9 is provided with a bracket 14, on whose legs in each case a tension spring 15 and 16 is mounted.
  • the other ends of the tension springs 15 and 16 are each mounted on one end of a transverse web 17, which is fixed to the end of the rail 8 facing away from the linear guide 2.
  • the sliding part 9 is pulled with the cam 11 against the transverse web 17, the cam 11 is thereby pressed against the curve of the plate 13, as will be seen later in detail.
  • a locking arrangement 18 is attached to the rail 8, which will also be described in detail later.
  • a recess 19 is mounted in the plate 13 in the central region. From this recess 19 from each extending on both sides a first Curved track 20 and a second curved track 21.
  • the drawer 1 is in the retracted position in the body.
  • the plate 13 is thus symmetrical with respect to the cam 11, this means that the cam 11 is located in the recess 19 of the curves, that is, the sliding part 9 is in the retracted position, which is achieved by the tension springs 15 and 16.
  • the latch 22 of the latch assembly 18 is in the unlocked state.
  • the drawer 1 can now be fully extended, as in Fig. 5 is shown.
  • the latch 22 which is latched in the slot 26 which is attached to the sliding part 9, the sliding part remains in the fully extended position.
  • the springs 15 and 16 are fully cocked.
  • the drawer 1 can now again against the retracted position in the direction of the arrow 25, as in Fig. 6 is shown, are pushed back.
  • the sliding part 9 is still in the locked position.
  • the cam 11 thus does not follow when pushing back the drawer 1 more of the second curved path 21, but enters the first curved path 20 a.
  • the cam 11 has reached the first cam 20, as shown in FIG Fig. 6 is shown, the bolt 22 enters the sphere of influence of the other curved path 23.
  • the latch 22 is lifted by the further curved path 23 and releases the slot 26.
  • a pivotable tongue 28 is disposed between the first two cam tracks 20. This pivotable tongue 28 locks when inserting the drawer 1, the respectively not used cam track 20. This ensures a safe flow is achieved. In the fully retracted position the situation is reached again, as in Fig. 2 has been shown.
  • the slope of the second curved path 21 seen from the recess 19 forth is less than the slope of the first curved path 20, also seen from the recess 19 ago. This ensures that when extending the drawer from the retracted position by the lower pitch of the second cam track 21, the force for tensioning the tension springs 15 and 16 is relatively low. As a result, the drawer 1 can be brought from the inserted to an extended position with little effort. As a result of the greater incline of the first curved track 20 as seen from the indentation 19, it is achieved that the retraction process for retracting the drawer 1 into the retracted position takes place with greater force. This ensures that the drawer 1 is pulled into the fully retracted position, caused by the tensile force of the tension springs 15 and 16 in cooperation with the sliding part 9 and the cam eleventh
  • the sliding part 9 can be seen, which is equipped with the cam 11.
  • the cam bears against the first curved path 20.
  • the latch assembly 18 in which the latch 22 is pivotally supported about an axis 30.
  • Fig. 8a is the sliding part 9 in the locked position.
  • the bolt 22 is thus outside the sphere of influence of the other cam track 23, the bolt 22 is pivoted about the compression spring 31 so that the bolt 22 in the slot 26 of the sliding part 9 engages.
  • the cam 11 is formed as a roller 32 which is rotatably supported on a journal 33, which journal 33 is fixed to the sliding part 9.
