Definitions

  • the present invention relates to a collection device, in particular for movable furniture parts, according to the preamble of claim 1.
  • the EP 1 362 527 discloses a draw-in device for drawers, in which a driver is guided along a housing and is biased by a spring in a collection device. To lock the driver in a biased position, it can be rotated about an axis parallel to the direction of movement. As a result, the feeder has a compact design. For unlocking a projecting on a rail pin moves against the driver to rotate it again so that the driver is then moved together with the running rail in a retraction position.
  • This feeder is suitable only for relatively light furniture parts, as only small forces can be transmitted via the pin on the rail and the filigree driver. In addition, it can come when pulling through the feed device to stop noise.
  • the driver is rotatable about an axis parallel to the direction of movement to be locked in a position with tensioned energy storage.
  • the driver can be formed as an elongate cartridge, which requires little space in the radial direction.
  • the driver is coupled to a damper, which slows down the closing movement, so that no loud impact noises arise upon reaching the closed position.
  • the feeder is particularly suitable for moving furniture parts, such as sliding doors or drawers, but other purposes are possible.
  • the damper is arranged in the housing, so that a particularly compact structure is present.
  • the driver may be formed substantially sleeve-shaped.
  • the damper can be accommodated at least partially within the driver in the closed position of the driver, so that only little installation space is required.
  • the energy accumulator is preferably designed as a helical spring, within which the damper is at least partially arranged. As a result, the space inside the coil spring can be optimally used.
  • the activator comprises at least one web with a run-on slope, by means of which the driver is rotatable.
  • the at least one web can be inserted into the driver in the longitudinal direction of the driver, so that driver and activator are fixed to one another.
  • the activator has two webs, which are fixable to recordings on the driver, so that a stable operation of the driver is given by the activator.
  • a holder is provided on an end face of the driver, which can be engaged behind by a head portion of at least one web of the activator in order to couple the activator with the driver.
  • the head section thus serves for coupling with the activator and can be rotated over the run-on slopes on the webs.
  • a connection with the damper for example with the piston rod of the damper, are manufactured, so that the holder has several functions at the same time.
  • an L-shaped guideway is formed on the housing, in which a radial projection of the driver is guided. At the shorter leg of the guideway then the driver can be locked or locked. It is also possible to provide two or more L-shaped guideways, on each of which a radial projection of the driver is guided.
  • the damper preferably comprises a damper housing and a piston rod which can be pushed or pulled out into the damper housing.
  • the damper housing may be cylindrical and be inserted into a receptacle of the housing.
  • the damper may be formed as a fluid damper, in particular silicone damper, air damper or other damper for braking the movement of the driver in the closing direction. In the opening direction, the damper can preferably pull apart easily.
  • a spring is provided for increasing the braking forces during a closing movement of the driver.
  • the spring may have a progressive spring characteristic and / or be designed as a compression spring, which is arranged around a piston rod of the damper. This allows a smooth closing, wherein the spring only slows down the closing movement, but the energy storage of the retracting device is stronger in order to move the driver securely in the closed position.
  • the feed device according to the invention is preferably used for fitting a sliding door, but can also be mounted on drawer runners for drawers. Other purposes are possible.
  • a collection device 1 comprises a housing 2, in which a driver 3 is guided displaceably.
  • the driver 3 can be coupled to an activator 5, which is connected to a fitting, for example a guided in a rail 6 carriage 4 for a sliding door. 7
  • FIG. 2 is the collection device in a position in which the activator 5 is coupled to the driver 3 straight.
  • the driver 3 is biased by a force accumulator 8 in the form of a coil spring in the closing direction, wherein the energy accumulator 8 is fixed with one end 80 to the driver 3 and with the opposite end 81 to the housing 2.
  • a force accumulator 8 is fixed with one end 80 to the driver 3 and with the opposite end 81 to the housing 2.
  • Within the force accumulator 8 is a cylindrical damper housing 9, in which a piston rod 10 is inserted and pulled out.
  • the piston rod 10 is inserted into a receptacle 11 of the damper housing 9 and formed so that a closing movement is decelerated.
  • the Damper be designed as a fluid damper, air damper or damper of another type, which exerts a braking force on the driver 3.
  • the piston rod 10 is connected at the end with a ball coupling 12 with a holder 30 on the driver 3.
  • the damper housing 9 is supported on a bottom 20 of the housing 2.
  • the energy storage 8 pulls the driver 3 together with the activator 5 and a furniture part coupled thereto in a closed position.
  • the movement is decelerated by the damper, the piston rod 10 is inserted into the damper housing 9 until the in FIG. 3 shown position is reached.
  • a spring 13 When moving the driver 3 in the closed position, a spring 13 is further compressed, which optionally ensures that the closing movement is further slowed down.
  • the spring 13 is formed as a compression spring and supported at one end on the damper housing 9 and on the opposite side to the holder 30. When moving the driver 3 in the closing direction, the spring 13 is compressed, wherein the spring force increases and thus for a further deceleration of Activator 5 and a coupled furniture part provides.
  • the activator 5 pulls the driver 3 in the opening direction, in which case the energy accumulator 8 is tensioned and the spring 13 is relaxed.
  • FIG. 5 the housing 2 of the collection device is shown in detail.
  • a recess 21 is provided, can be inserted into the webs of the damper housing 9 in order to position this exactly.
  • a groove-shaped guide track 22 is further formed with an angled end portion 23, which serves to guide the driver 3.
  • the driver 3 is in FIG. 6 shown in detail.
  • the driver 3 is formed substantially sleeve-shaped and comprises a radially outwardly projecting projection 32 which is guided in the guide track 22 and upon reaching the angled end portion 23 ensures that the driver 3 is rotated about an axis parallel to the direction of movement.
  • the driver 3 comprises at a front end a holder 30 to which a coupling 12 of the piston rod 10 is fixable. On the holder 30 recesses 31 are further formed, which serve for connection to the activator 5.
  • the activator 5 is in FIG. 7 illustrated in detail and formed in this embodiment, integral with a carriage 4 with rollers 60 to which a holder 61 is fixed for a sliding door.
  • the activator 5 has on each side two protruding ridges 50 which can be coupled to a driver 3 of a collection device, wherein in the present case only one side of the activator 5 is described in more detail.
  • Each web 50 comprises a cross section which can be inserted into the ring-segment-shaped recesses 31 of the driver 3.
  • each web 50 has a thickened head portion 51, to which a recess 52 connects.
  • a projection 54 with a run-on slope 53 is formed on the web 50.
  • the starting bevel 53 on the projection 54 comes against a contact surface of the holder 30 and rotates about an axis parallel to the direction of movement of the activator 5 and the driver 3.
  • the rotational movement of the driver 3 is the projection 32 moved out of the angled end portion 23, as shown in FIG FIG. 8B is shown.
  • the driver 3 can now be moved by the force of the force accumulator 8 in the feed direction.
  • the rotational movement of the driver 3 further causes the head portions 51 engage behind the holder 50 on the webs 50, so that now the activator 5 is retracted by the driver 3 in the closing direction.
  • the driver 3 is shown together with the damper.
  • the piston rod 10 of the damper is disposed within the driver 3 and fixed at the end via a coupling 12 to the holder 30.
  • the piston rod 10 is arranged centrally in the driver 3, so that in the region of the annular segment-shaped recesses 31, the webs 50 of the activator 5 can engage easily, in order then to be fixed after rotation of the driver 3 to the radial webs of the holder 30 can.
  • an opening movement of the activator 5 pulls the driver 3 against the force of the force accumulator 8 in the opening direction until the driver 3 reaches the angled end portion 23 and the projection 32 causes a rotation of the driver 3.
  • the head portions 51 are released on the webs 50 and can be pulled out of the recesses 31 of the driver 3 again.
  • the collection device is used for a sliding door.
  • a pullout guide 40 is provided, on which a drawer 41 is held.
