Definitions

  • the present invention relates to a telescopic tube for a vacuum cleaner, and more particularly to a three part telescopic tube.
  • Telescopic tubes to be able to adjust the length of a vacuum cleaner tube.
  • One advantage with telescopic vacuum cleaner tubes is to be able to optimize the tube length for a specific cleaning task or for the height of a person that is using the vacuum cleaner.
  • Telescopic tubes also provide the benefit of minimizing the length of the tube when not in use, thus facilitated storage is provided.
  • the basic concept of telescopic tubes is to have an inner tube that is movably arranged within an outer tube.
  • the tubes are further provided with a locking member, for instance a simple form of recess and engagement means that is released by means of a control mechanism, for instance by pressing down a release button, while the user pushes or pulls out the movable tube with respect to the outer tube.
  • a locking member for instance a simple form of recess and engagement means that is released by means of a control mechanism, for instance by pressing down a release button, while the user pushes or pulls out the movable tube with respect to the outer tube.
  • the locking member keeps the inner tube in position.
  • Telescopic tubes comprising three tubes joined with two telescopic links in the same unit are available on the market today. With two telescopic links a telescopic tube, which can be minimized in respect to its maximum length, i.e. when the two movable tubes are fully extended, is obtained.
  • the two telescopic links are controlled by two separate control mechanisms, each controlling one individual telescopic link.
  • a problem with this known three-part telescopic tube is that the adjusting the length of the tube by operating the telescopic links can be experienced as troublesome.
  • This object may be achieved by a telescopic tube for a vacuum cleaner according to the present invention as defined in claim 1 .
  • a telescopic tube for a vacuum cleaner comprising a first inner tube, a second inner tube, and an outer tube.
  • the first and second inner tubes are slidably arranged inside the outer tube and the first and second inner tubes are lockable relative the outer tube.
  • the first inner tube is arranged relative to a first end portion of the outer tube to form a first telescopic link with the outer tube such that the first inner tube is extendable from the first end portion.
  • the second inner tube is arranged relative to a second end portion of the outer tube to form a second telescopic link with the outer tube such that the second inner tube is extendable from the second end portion.
  • a three-part telescopic tube for a vacuum cleaner where the outer tube encompasses two inner tubes that each are arranged to form a telescopic link at a respective end of the outer tube.
  • the outer tube forms the intermediate tube of the three-part tube while it at the same time is fully accessible in any position: the fully extended position, the fully retracted position or any intermediate position between these positions.
  • both tubes are easily accessible at their respective ends at all times, and the total length of the tube is easily adjustable.
  • the first inner tube and the first end portion of the outer tube are arranged with a first releasable locking member, and the second inner tube and the second end portion of the outer tube are arranged with a second releasable locking member. Due to the releasable locking members, the tubes can be securably locked relative each other in a locking position of the locking members and easily movable relative each other in a released position of the locking members.
  • the telescopic functions of the two respective telescopic links can be easily controlled by a control mechanism for the locking members, which control mechanism is arranged on the outside of the outer tube.
  • control mechanism is arranged to control the first and second locking members simultaneously.
  • This exemplary embodiment of the invention provides a telescopic three-part tube, that has two telescopic links that are controlled with only one control mechanism that is arranged to control the first and second locking members simultaneously.
  • the telescopic tube is thereby allowed to be operated from retracted to extended positions by a one grip operation, which may simplify the length adjustment of the telescopic tube.
  • Using one control mechanism also may simplify the construction complexity compared with prior three-part tubes, i.e. fewer parts can be used, and thus the manufacturing costs of the tube can be decreased.
  • control mechanism comprises an interconnecting part between the first locking member and the second locking member, which is favourable for allowing simultaneous control of the first and second locking member.
  • the interconnecting part is at least a part of a cylinder shell surface encompassing the outer tube. Since the outer tube is accessible in all position it allows for a common grip when extending and/or retracting the first and second telescopic links.
  • the interconnecting part may be an integrated part of the outer tube.
  • the first locking member and the second locking member are arranged to be released when receiving a longitudinally directed force in excess of a predefined threshold force.
  • the operation of the telescopic tube is user friendly. The user only has to hold the outer tube with one hand and push or pull the inner tubes with the other hand to change the inner tube positions.
  • the control mechanism includes a releasable locking device for releasing the first and second locking members allowing the repositioning of the inner tubes to a required position.
  • the locking device When deactivating the locking device and after reaching the new required position, the locking device then locks the telescopic tube in the new position.
  • the outer tube has a larger diameter than the first inner tube and the second inner tube, and the second inner tube has a larger diameter than the first inner tube.
  • the first inner tube can be retracted into the second inner tube, which in turn can be retracted into the outer tube. This allows for achieving a reduced length of the telescopic tube in the fully retracted position. Thus, valuable space can be saved when storing the tube.
  • the position of the inner tubes relative to the outer tube is continuously adjustable, thus making it possible for the user to make a precise adjustment of the length to fit to his or her own height or to some other required criteria, like for instance required radial range of the vacuum cleaner tube.
  • the position of the inner tubes relative to the outer tube is stepwise adjustable, allowing fixed preferred positions of the telescopic tube.
  • At least one of the first and second inner tubes is connectable to a vacuum cleaner nozzle.
  • the first inner tube has a smaller diameter than the second inner tube, it may be more favorable to connect the vacuum cleaner nozzle to the first inner tube than the second inner tube. Due to the first inner tube having a smaller diameter than the second inner tube, the air steam will flow from a smaller diameter tube to a greater diameter tube, reducing the risk that dust particles in the air stream will clog the tube or that larger debris will get stuck further up the tube.
  • placing the first inner tube with the smallest diameter closest to the vacuum cleaner nozzle may be favorable to the weight distribution of the vacuum cleaner tube, and may make the telescopic tube easier to manoeuvre.
  • the telescopic tube for a vacuum cleaner is connectable to a vacuum cleaner housing or a flexible tube.
  • the telescopic tube is advantageously connected directly to the vacuum cleaner housing or to a flexible tube, depending on the type of vacuum cleaner.
  • one end of the telescopic tube is preferably placed directly on the vacuum cleaner housing while the other end is provided with a handle, while on a canister model the telescopic tube is used as the vacuuming tube and is connected to a vacuum cleaner nozzle at one end and to a flexible tube at the other end.
  • the telescopic tube is used as a vacuuming tube and is connected to a vacuum cleaner nozzle at one end, and to the vacuum cleaner housing at the other end, as shown in FIG. 5 .
