Description

technical area

The Innovation relates to vacuum cleaner parts and in particular a constructive Improvement of the telescopic suction tube of household vacuum cleaners.

State of technology

Suction Tubes Vacuum cleaners usually have an outer tube, a telescopic retractable inner tube and in between a locking mechanism, the two pipes coupled together so that the length of the Suction tube can be adjusted. After releasing the locking mechanism can the inner tube telescoped as desired to a suitable length become. Afterwards, and inner tube interlocked again. There are many types of latch mechanisms and correspondingly many inner and outer tubes. Examples are given in Chinese patents CN200510038703.4, CN200420079535.4 and CN03221741.2.

Although the vacuum cleaners are length adaptable Suction pipes possess, which simplifies their handling, so can be Nevertheless, certain areas of the house, for example, below or above the cabinets, difficult to reach. That's because of the one-dimensional changeability the suction pipes.

Summary the innovation

The The present invention overcomes the above disadvantages of the prior art of technology and provides a portable telescopic suction tube group for vacuum cleaners ready when you after removing the inner tube from the outer tube can easily adjust the axis angle between inner and outer tube. Thereby The dust can be easily removed from almost anywhere in the house.

The Telescopic suction tube group according to the invention for vacuum cleaners includes at least one telescopic inner tube, an outer tube and a first locking mechanism between inner and outer tube, characterized in that the inner tube with the outer tube via a Ball joint pair is coupled, consisting of a ball joint head and a ball joint socket, wherein the ball joint head with one end the inner tube is connected and the ball joint socket in the outer tube is inserted.

Becomes the inner tube from the outer tube pulled, so can between the two tubes as desired means of the ball joint pair an axis shear angle can be set - under Forming an L-shape - which you easily dust over or over under furniture can remove.

A Further improvement is that of the connected to the inner tube Ball joint head has a positioning recess. The adjusting knob of the first locking mechanism on the outer tube then has a protruding End with a positioning part, which is in the positioning dent can intervene. After release of the first locking mechanism by the adjusting knob becomes the inner tube of the outer tube when in use pulled, set an axial shear angle between the two tubes, the adjusting knob is reset and the positioning parts are fastened in the positioning recess, so that inner and outer tube are locked together. This remains even when exposed an external force get the set angle. The positioning and locking devices the pipe group can released after vacuuming in the same way on the knob become, what for the user is very comfortable.

Detailed description of the preferred embodiments

The 1 . 2 and 3 show a telescopic assembly for vacuum cleaners according to the invention. The main parts comprise a central tube 1 , an inner tube 2 , an outer tube 3 , a small inner lining cuff 4 , a sealing ring 5 , a push-button plate 6 , a movable bolt block 7 , a movable sliding block 8th , a feather 9 , a bolt 10 , a groove 11 , a ball joint head 12 , a ball joint socket 13 , a large inner lining cuff 14 , a recording 15 a detachable mounting head connection, a head of a detachable mounting head connection 16 , a sealing ring 17 , a button closure 18 , a conical spring 19 , a button closure part 20 , a button closure cover 21 , a second lock hole 22 for positioning the central tube in the inner tube 2 , a first bolt hole 20 for positioning the condyle 12 in the inner tube 2 ,

The center tube 1 can telescope into the inner tube 2 be inserted over the small inner lining cuff 4 , attached to the flared end of the inner tube 2 , A second locking mechanism, consisting of a push-button plate 6 , a movable bolt block 7 , a movable sliding block 8th , a spring 9 , a bolt 10 and a groove 11 , is at the flared end of the inner tube 2 attached, with the movable bolt block 7 and the movable shift block 8th are arranged in a herringbone-like concave depression on the central tube. They are used when positioning and mooring using the push-button plate 6 actuated. Their exact construction is disclosed in CN200510038703.4.

On the inner tube end face opposite the flanged end is a first latch hole 23 , A positioning projection and a shoulder for limiting the axial position are provided on the outside of the ball joint head. The ball joint head 12 that with the ball joint socket 13 engages is in the inner tube by detecting the positioning projection in the first latch hole 23 attached. The big inner lining cuff 14 is in the flared end of the outer tube 3 attached, and the ball joint cuff 13 Can telescope into the large inner lining cuff 14 be inserted. As a result, after the inner tube has been pulled out, the axial angle between the inner and outer tubes can be adjusted by means of the ball joint pair. A first locking mechanism, consisting of a button closure 18 , a conical spring 19 , a button closure part 20 , a button closure cover 21 , is mounted on the crimped end of the outer tube. Its exact construction is not explained here, but it is to be found in the prior art. The button closure part 20 has a longer end with a position hook. The ball joint head 12 in the inner tube has a Positionierausnehmung, in which the position hook of the elongated end of the button closure part 20 can be fixed in position after the shear angle between the two tubes is set. In addition, the inner tube has an axially extending groove into which a projection on the outer tube may spring during assembly, so that a mutually rotating inner and outer tube is avoided. This makes the telescope setting more comfortable.

The other end of the outer tube 3 which opposes the curled end is with a release mounting head connection receptacle 15 inserted. This has an internal concave groove and forms an angle to the axial alignment. The inner concave groove forms a pair of hinges with the protruding peripheral edge of the connecting head 16 the demountable mounting head, wherein the protruding edge forms a corresponding axial angle. The angle of the vacuum cleaner head used in the mounting head connector head 16 can be mounted in use by turning the mounting head connection head 16 be set. This makes his use easier.

• 1. Durch die ineinander greifende Konstruktion der drei Rohre ist die Rohrbaugruppe nach dem Zusammenklappen kompakter und sie kann einfacher und billiger mit den Staubsaugern versandt und gelagert werden.
• 2. Das Mittelteil der Rohrbaugruppe kann über das Kugelgelenkpaar jeden beliebigen Winkel annehmen, wodurch deren Gebrauch handlicher wird.
• 3. Das mit dem Staubsaugerkopf zusammengebaute Ende kann durch Drehen gekrümmt werden, so dass man nicht Staubsaugerköpfe mit verschiedenen Winkeln wie im Stand der Technik verwenden muss.

The telescopic tube group according to the invention for vacuum cleaners according to the invention can be handled conveniently and easily and has a variety of functions and properties:

• 1. Due to the interlocking construction of the three tubes, the tube assembly is more compact after folding and it can be shipped easier and cheaper with the vacuum cleaners and stored.
• 2. The middle part of the pipe assembly can take any angle through the ball joint pair, making their use handy.
• 3. The end assembled with the vacuum cleaner head can be curved by turning, so you do not have to use vacuum cleaner heads with different angles as in the prior art.

Next the embodiment described above The present utility model includes still other embodiments. So can For example, the various locking mechanisms of the state the technique used. The telescopic central tube can, for example. be inserted into an inner tube end without the inner lining. At the other end of the outer tube an internal concave recess may be at an angle to the axis, so that the inner concave recess forms a joint pair with the projecting peripheral edge of the mounting connection head, wherein the protruding edge forms a corresponding axial angle. The present utility model extends to these other embodiments and their equivalents.
