Definitions
- the invention relates to a telescopic vacuum cleaner suction pipe with an outer tube and an inner tube with locking recesses into which one that couples the outer tube and one that can be operated manually Slider or push button unlockable, under the action of a spring standing locking element engages.
- Vacuum cleaner suction pipes of the above type are known essentially by the type and design of the slide differentiate between the push button and the spring. Instead of many be on Subject of DE 195 28 814 C1 referenced. At this Embodiment is the locking element when the slide is not actuated held in its locked position by a spring under pressure and when the slide is actuated against the force of the spring to one Relative displacement of inner tube and outer tube in his Unlocked position moved.
- the locking element consists of two at an opposite acute angle to the longitudinal axis of the outer tube on an inclined sliding plane one in one Recess of the outer tube inserted in a form-fitting manner Guide body slidable, in separate locking recesses engaging clamp bodies, of which the relative movement from inside to outside tube locking clamps to solve this Locked position along the slide out of its recess its inclined sliding plane is displaceable.
- Such two-part telescopic tubes have an insertion length between 530 mm and 600 mm on and with a full Extension length between approx. 880 mm and 1030 mm.
- a bigger one Extension length is often desirable in practice, but fails because of the then too large insertion length, which is not only the packaging and Transport costs increased, but also a correspondingly larger Warehousing costs.
- a remedy could be e.g. three-part telescopic vacuum cleaner suction pipe create.
- this is linked to the problem that one hand the locking principle of locking between the first interior and the Outer tube can not be transferred to the third telescopic tube, because then the inner tube would no longer move in the outer tube.
- Another problem arises from the requirement that one three-part vacuum cleaner tube the flow losses are not may increase because otherwise the performance of the previous used motors prove inadequate or with a unwanted drop in suction power could be associated.
- the invention sets now the invention.
- Characteristics a) and d) a cross-sectional narrowing compared to the previous two-part telescopic vacuum cleaner suction pipe prevented.
- Feature b) states that the outer tube with the third tube only in extended Position near the end areas by a non-positive and / or positive locking element is detachably coupled.
