Definitions

  • the invention relates to a device for absorbing a shock when a movable component, for instance a pivotable panel such as a door, a hatch or a swivel window, or a slidable element such as a sliding window or a drawer, is closed against a fixed component such as a frame edge, and/or for preventing rattling that results from play between this closed fixed component and this movable component .
  • a movable component for instance a pivotable panel such as a door, a hatch or a swivel window, or a slidable element such as a sliding window or a drawer
  • the device of the type stated in the preamble comprises according to the invention:
  • a stop element which is intended to be accommodated slidably in lengthwise direction in a hole arranged for this purpose in the fixed or the movable component, and having a free end which is intended for pressure force-transferring co-action with the other component;
  • the spring means are connected on their one end zone to the stop element and on their other end zone to the hole such that during operation the stop element is displaceable between a free, pressed-outward end position, which is defined by the length of the spring means in their non-tensioned position, and a pressed-in position.
  • An advantage of the device according to the invention is that it comprises only two components, i.e. the stop element and the spring means.
  • the device according to the invention can hereby be manufactured simply and/or inexpensively.
  • the spring means comprise a draw spring.
  • a draw spring has the advantage that, when the movable component is closed against the fixed component, the stop element is pressed into the hole with elongation of the draw spring, whereby the kinetic energy of the movable component is at least partially converted to potential energy in the draw spring, whereby the shock during closure is prevented or at least substantially reduced.
  • the draw spring In the closed position of the movable component the draw spring moreover tends to be displaced to its non-tensioned position and to press the stop element outward, whereby the stop element exerts a pressure on the movable component and so prevents rattling as a result of play in the lock.
  • the spring has on its other end zone at least one widened portion, whereby the spring fits only up to this widened portion into the hole.
  • Such a widened portion provides a simple connection between the spring means and the hole.
  • the draw spring comprises a number of windings, wherein the widened portion is formed by a winding on the other end zone of the spring, this winding having a diameter larger than the diameter of the hole, and wherein the other windings have a diameter smaller than the diameter of the hole.
  • a widened portion is provided in simple manner by embodying an end winding of the spring with a greater diameter, whereby the spring fits only as far as this winding into the hole and a simple connection between the spring and the hole thus takes place .
  • the spring means extend round at least a part of the stop element .
  • connection between the stop element and the spring means is realized easily in an embodiment of the device according to the invention in which the stop element has on its end zone remote from the free end a recess in which the one end zone of the spring is received with clamping fit.
  • the free end of the stop element is optionally provided with a layer of flexible, resiliently compressible material.
  • a layer can absorb a shock during closing of the movable component and can efficiently prevent rattling.
  • the invention further relates to an assembly of a fixed component, such as a frame edge, and a movable component, for instance a pivotable panel such as a door, a hatch or a swivel window, or a slidable element such as a sliding window or a drawer, wherein there is arranged in the fixed component or the movable component a device as described above for absorbing a shock when the movable component is closed against the fixed component and/or for preventing rattling that results from play between this closed fixed component and this movable component, which device comprises:
  • a stop element which is intended to be accommodated slidably in lengthwise direction in a hole arranged for this purpose in the fixed or the movable component, and having a free end which is intended for pressure force-transferring co-action with the other component;
  • the spring means are connected on their one end zone to the stop element and on their other end zone to the hole such that during operation the stop element is displaceable between a free, pressed-outward end position, which is defined by the length of the spring means in their non-tensioned position, and a pressed-in position.
  • the movable component is preferably connected movably to a side of the fixed component, and wherein an opposite side of the fixed component is provided with the hole in which the device is accommodated fittingly such that the device extends substantially perpendicularly relative to the surface of the movable component which closes against the fixed component when the movable component is situated in a closed position.
  • Rattling is effectively prevented when the device is arranged at this location in the fixed component and extends perpendicularly relative to the surface of the movable component which closes against the fixed component when the movable component is situated in a closed position.
  • FIGS. 1A and IB show respectively a perspective view and a longitudinal section of a shock and rattle damper according to the invention in non-tensioned position;
  • figures 2A and 2B show respectively a perspective view and a longitudinal section of a shock and rattle damper of figure 1 in pressed-in position;
  • figure 3 is a perspective view of the shock and rattle damper of figure 1 in mounted position.
  • figures 4A and 4B show a longitudinal section of the shock and rattle damper of figure 1 in respectively the mounted, non-tensioned position and the pressed-in position.
  • Figures 1A and IB show a shock and rattle damper 1 with a stop element 2 which has a free end 3.
  • Stop element 2 has on an end zone a recess 4 in which an end zone 7 of a draw spring 5 is received with clamping fit.
  • End zone 7 of draw spring 5 extends for this purpose radially inward from the winding periphery of spring 5.
  • the stop element 2 takes a hollow form, wherein two recesses 4 are arranged in the edge of stop element 2.
  • Spring 5 extends round at least a part of stop element 2.
  • Figures 1A and IB show that spring 5 has a number of windings, wherein an end winding 6 on the other end zone of spring 5 has a diameter greater than the diameter of the other windings.
  • the shock and rattle damper 1 of figure 1 is shown in pressed-in position in figures 2A and 2B. In this pressed-in position the end winding 6 on the other end zone of spring 5 extends close to the free end 3 of stop element 2.
  • FIGs 3, 4A and 4B show shock and rattle damper 1 in mounted situation in a frame 20.
  • frame 20 Arranged in frame 20 is a drilled hole 21 in which stop element 2 with the spring 5 extending therearound is accommodated slidably in lengthwise direction.
  • Hole 21 in frame 20 is arranged in a side of frame 20 located opposite the side of frame 20 on which door 22 is hingedly suspended.
  • shock and rattle damper 1 extends perpendicularly relative to surface 23 of door 22 which closes against frame 20, at least in closed position of door 22.
  • end winding 6 has a diameter greater than the diameter of hole 21, whereby shock and rattle damper 1 fits up to end winding 6 into hole 21.
  • the other windings have a diameter smaller than the diameter of hole 21. It is noted that any widening of spring 5 close to its end zone facing toward the free end 3 can be suitable instead of the end winding 6. Spring 5 could thus be provided for instance with a flange such that spring 5 fits no further into hole 21 than up to this flange. It is also noted that it will be apparent that the length of hole 21 must be greater than the length of stop element 2 as measured between its rear surface 24 and a free end surface 16 of the free end 3.
  • FIG 4B the shock and rattle damper 1 is shown arranged in frame 20 in a pressed-in position.
  • the kinetic energy thereof is at least partially converted to potential energy in spring 5 because spring 5 is elongated, whereby the shock during closure is prevented, or at least substantially reduced.
  • the shock and rattle damper 1 further prevents rattling resulting from play in the lock.
  • spring 5 will urge stop element 2 to its free, pressed-outward end position because spring 5 displaces to its non-tensioned position, such that shock and rattle damper 1 is ready to absorb another shock when the door 22 is closed once again.
  • the free, pressed-outward end position is defined by the length of spring 5 in its non-tensioned
  • the length of the part of stop element 2 in the pressed-outward end position outside hole 21 is the length of stop element 2 minus the length of spring 5 in its tensioned position .
  • stop element 2 can be provided with a layer of flexible, resiliently compressible material .
  • Stop element 2 can be manufactured by injection moulding from an appropriate plastic. Owing to its simple form the stop element 2 can be manufactured in simple and inexpensive manner.
  • shock and rattle damper 1 can take place in simple manner by arranging spring 5 round stop element 2 and fixedly clamping the one end zone of spring 5 into recess 4 of stop element 2.
