Definitions

  • the invention relates to a vacuum cleaner suction tube with at least one inner tube, at least one outer tube, and at least one locking device, wherein the inner tube has a toothed strip, wherein the locking device is attached to the outer tube, wherein the locking device by manual operation by a user from a locking position in a Release position can be brought, wherein the locking device comprises a rack, and wherein in the locking position, the rack is held in engagement with the rack of the inner tube, whereby the position of the inner tube is fixed relative to the outer tube.
  • Vacuum cleaner suction pipes are known in a variety of configurations in the art. Vacuum cleaner suction pipes establish the connection between the suction hose of a vacuum cleaner and the suction tool, for example a floor nozzle. In order to adapt the length of the vacuum cleaner suction tube to the individual requirements of a user, vacuum cleaner suction pipes are variable in their length, for example, by an inner tube is guided telescopically in an outer tube. The length of the vacuum cleaner suction tube is adjusted by relative displacement of the inner tube to the outer tube stepwise. The shortest path of a change in length is determined, for example, by the minimum distance of a locking recesses, which serves to lock the tubes relative to each other.
  • the EP 0 937 435 A2 discloses a vacuum cleaner suction tube having an inner tube and an outer tube, wherein the inner tube has embossed recesses which cooperate with a locking mechanism attached to the outer tube.
  • the locking mechanism has elastic latching hooks which engage in a latching position in the embossed recesses in the inner tube and thus determine the position of the inner tube relative to the outer tube.
  • the known from the prior art vacuum cleaner suction tubes have the disadvantage that a sufficiently temporary stabilization of the adjusted position between the inner tube and outer tube can be realized only with an additional spring force acting on the spring elements, so that even with dissolved locking mechanism by the Users must always overcome a spring force to move the inner tube relative to the outer tube, which means an extra effort for the user. Furthermore, the known vacuum cleaner suction tubes have the disadvantage that the distance between the locking positions is relatively large, whereby only imprecise adjustment is possible.
  • the present invention seeks to provide a vacuum cleaner suction tube, which allows a precise and straightforward adjustment of the length.
  • a vacuum cleaner suction tube in that the locking device can be moved by displacement relative to the outer tube and in the axial direction of the outer tube in the release position, and that the rack in the release position by a relative force between the outer tube and inner tube without the influence of a spring force can be pushed out of engagement with the rack by the tooth flanks of the teeth of the rack push the tooth flanks of the teeth of the rack upwards, whereby the inner tube is displaceable relative to the outer tube.
  • the locking device can thus be brought into at least one release position by manual displacement in the axial direction of the outer tube.
  • the locking device releases a movement of the rack out of engagement with the rack, so that the rack without the influence of a spring force, for example, in a recess is pressed back, whereby the inner tube and the outer tube are relatively displaceable.
  • the inner tube is guided in the outer tube, wherein preferably the outer diameter of the inner tube corresponds to the inner diameter of the outer tube.
  • the length of the vacuum cleaner suction tube ie the length of the outer tube with subsequent inner tube, is adjusted by moving the inner tube relative to the outer tube or the outer tube relative to the inner tube.
  • the space enclosed by the inner tube and by the outer tube forms from the end of the inner tube facing away from the outer tube to the end of the outer tube facing away from the inner tube that can be used during operation of the vacuum cleaner suction tube.
  • a locking device which fixes the position of the inner tube to the outer tube and of the outer tube to the inner tube, respectively.
  • the locking device has a rack, the teeth of which are held in the locking position in engagement with the teeth of the rack in a wall of the inner tube, whereby a relative movement of the inner tube is blocked to the outer tube.
  • the intermeshing teeth of the rack and the rack lead to a power transmission between inner tube and outer tube, which prevents relative movement of the inner tube to the outer tube.
  • the rack in the inner tube is preferably embossed in the wall of the inner tube.
  • As a material for the inner tube and the outer tube is preferably a stainless steel.
  • the locking device is in the unactuated state advantageous in the locked position, so that a relative movement of the outer tube is prevented relative to the inner tube without actuation of the user.
  • a user manually spins the locking device from the locking position to the release position by manually displacing the locking device in the axial direction of the outer tube relative to the outer tube, movement of the rack is released from engagement with the rack. It is not necessary that all components of the locking device are moved in the axial direction, but it is sufficient if only a single component or a plurality of components of the locking device to be moved.
  • the rack can thus move radially in the release position to the vacuum cleaner suction tube, without a spring force or other elastic force acting on the rack.
  • the rack is preferably held in its position positively with little play.
  • the locking device is in the release position and a user generates an axial force acting relative to the inner tube between the outer tube, for example, by holding the outer tube and exerts an axial force on the inner tube, the tooth flanks of the teeth of the toothed rack on the flanks of the teeth Rack upwards, so that the rack moves ratchet-like on the rack, while the inner tube is telescoped relative to the outer tube.
  • the rack can thus move without spring force on the rack, as long as the locking device is in the release position.
  • the rack is held only by its weight in engagement with the rack, which can be overcome by applying the relative force.
  • the teeth of the rack and the teeth of the rack are the same size, so that an advantageous engagement of the teeth takes place in each other.
  • the teeth of the rack and the teeth of the rack further preferably also have a straight toothing, so that in the release position, the flanks can advantageously slide past each other.
  • the teeth of the rack and the teeth of the rack are arranged orthogonal to the axis of the outer tube and the inner tube.
  • the vacuum cleaner suction tube described has the advantage that the operation of the locking device takes place in the same direction with the adjustment of the inner tube and the outer tube, whereby a particularly advantageous adjustment can be made by a user, as the forces for unlocking and adjusting in the same axis be applied. Consequently, a user can grasp the locking device with one hand in order to bring it into the release position while applying a displacement force to the inner tube with the other hand so that the inner tube moves relative to the outer tube and setting the length of the vacuum cleaner. Suction tube takes place.
  • the plurality of teeth on the rack and the rack has over locking devices only with one or two locking hooks the advantage that a larger area is available for power transmission. Due to the large area, a spring force for holding the latching hooks in their engaged position becomes unnecessary.
  • a plurality of inner tubes or a plurality of outer tubes is present, so that a plurality of locking devices is provided, whereby the vacuum cleaner suction tube is adjustable in several places, which preferably corresponds to the number of locking devices.

  • the user now diverts the locking device from the locking position - by displacing the locking device relative to the outer tube in its axial direction, the spring is elongated or compressed, so that it causes a restoring force from the release position to the locking position.
  • the locking device is thus always automatically returned to the locking position, when the user does not act on the locking device. For the release position this means that the locking device must be actively held by the user in the release position to adjust the length of the vacuum cleaner suction tube.
  • the spring is designed, for example, as a helical spring which is subjected to tension and / or pressure.
