Definitions
- the present invention relates to a length-adjustable tube, especially for ski or Walking sticks according to the preamble of claim 1.
- the expansion element used in the expansion device in Generally is made of a relatively hard plastic a problem in that to clamp the Spreading device the relevant expansion element in the outer tube already determined at the beginning of the spreading movement have to be. This is in terms of diameter tolerances of outer tube and inner tube of a length-adjustable tube not so easy to guarantee.
- the object of the present invention is therefore a length-adjustable tube of the type mentioned at the beginning create, in which the friction element in a simple manner on Spreading element can be attached and a gripping the Spreading device inside the outer tube in any case is guaranteed.
- the features are provided according to claim 2, so that a resilient application and holding of the slotted ring on the expansion element is possible.
- the features according to claim 2 are provided. This also prevents possible damage to the friction element if the diameter differences between the inner and outer tubes are too small.
- Connection section of a length-adjustable tube 10 is a Inner tube 11 guided in an outer tube 12 telescopically.
- the inner tube 11 at its end facing the outer tube 12 provided with a spreading device 15 and 115, respectively which the inner tube 11 in the outer tube 12 at any Positions can be fixed by clamping.
- the in Figures 1 and 2 according to a first Spreading device 15 shown embodiment has an outer element in the form of an expansion element 16, a Inner element 17 and an adjusting screw or Male threaded rod 18.
- Removal rod 18 is in a manner not shown with her an end region rotatably at the end 13 of the inner tube 11 held.
- the inner element 17 is on the outer threaded rod 18 screwed with its axial central internal thread 21.
- the inner element 17 is provided on the outside with a cone 22 or conical.
- the outer threaded rod 18 penetrates the internally threaded bore 21 of the inner element 17 and is at its protruding end with a stop part 26, such as for example, a lock nut rotatably connected.
- the Stop part 26 engages over the wider forehead of the inner element 17 partially.
- the outside expansion element 16 has an inner cone or Inner cone 27, the slope of that of the outer cone or cone 22 of the inner element 17 corresponds.
- the inner element 17 is in the counter-directed expansion element 16 is added without play, in the illustrated embodiment, outer cone 22 and Inner cone 27 are of equal length.
- that is Expansion element made of a plastic, while the inner element 17th is made of metal. That is at its front end on the outer circumference essentially cylindrical Spreading element 16 with an insertion or receiving part 28 provided with a spherical outer peripheral surface is.
- the expansion element 16 is both from its in Insertion direction front end as well as from its rear End of provided with a slot arrangement, each made two diametrically opposed slots 31 there, the pairs of slots in a manner not shown are circumferentially offset from one another by 90 °.
- the expansion element 16 has one behind the other in the axial direction arranged annular grooves 34 and 35, in each one with a axial slot 36 provided ring 37 is inserted.
- the Ring 37 slotted on one side has two layers or two layers formed, the inner in the annular groove 34 and 35 of the Spreading element 16 lying layer 42 made of a relatively hard Plastic is made, while the outer layer 43 by a soft elastic, with a non-slip surface Plastic is formed and the outer peripheral surface 19 of the Spreading element 16 protrudes.
- Layer 34 of the ring 37 slotted on one side is axial Towards crowned.
- This spherical outer surface 38 is such shaped so that its ends have an outer diameter that the outer diameter of the peripheral surface 19 of the expansion element 16 either corresponds or is preferably smaller.
- the one-sided slotted ring 37 can thus easily resilient expansion into the annular groove 34, 35 of the expansion element 16 be placed so that it is then under spring force and in Circumferentially rotatably abuts the expansion element 16, however is held axially immovably in the annular groove 34 or 35.
- the spreading device 115 has a pipe longitudinal direction extending screw 118, which is held on the inner tube 11 in a rotationally fixed manner and an expansion element 116 with an internal thread 121 which only over an axial portion of the Spreading element 116 extends.
- the one causing the spreading movement of the spreading element 116 Screw 118 has at its front end in extension of the Threaded portion 120 a conical tip 123.
- Das Spreading element 116 has a cylindrical portion 146, of which the internal thread 121 runs out and to which one in Diameter larger slotted cylindrical section 147 integrally connects the intersecting slots 131 and 132 is divided into four jaws 151.
- the internal thread 121 protrudes into the larger cylindrical section 147 and merges into a conical blind hole 152, at the Inner wall the cone tip 123 of the screw 118 for Spreading the jaws 151 comes to rest.
- annular groove 134 On the larger diameter slotted cylindrical section 147 an annular groove 134 is provided, in which, as in the first Embodiment a ring provided with a slot 136 137 is inserted.
- This one-sided slotted ring 137 is formed of two layers or two layers and thus has corresponding to the ring 37 in the first embodiment designed layers 142 and 143. layers 142 and 143 have the same designs, materials and properties like layers 42 and 43 of ring 37.
- the present invention is that of the spreading element 16 or 116 brought soft elastic ring not slotted but carried out continuously.
- a soft elastic ring is to over the expansion part to a corresponding ring groove to be brought, elastically expandable.
- the expansion part two injection molded half shells or one half divided element, which half-shells or halves by means are held together by a continuous soft elastic ring.
- the attachment of the friction elements on the circumference of the Spreading part can be done by gluing or welding; it can but also a positive connection can be provided, for example in the form of a locking pin, one Dovetail connection or a snap connection according to Art of a circlip.
- FIGS. 6 to 9 show flexible elements 156 and 157, respectively or 158, the in their properties and modes of action outer soft elastic layers 43, 143 of the one-sided slotted rings 37, 137 correspond.
- These soft elastic Elements 156, 157 and 158 are immediately in form 161 or 162 or 163 of the expansion element 116 ', 116 "or 116' '' introduced or injected.
- the soft elastic elements 156 and 157 are elongated according to Figures 6 and 8 rectangular, the in the embodiment of Figure 6 Formations 161 have a closed edge, while 8, the formations 162 at one end of the Spreading element 116 "are open.
- the soft elastic elements 156 and 157 are at least in the axial direction crowned outer surface and each in one of the Clamping jaws 151 ', 151' 'introduced and thus over the circumference of the expansion element 116 ', 116' 'arranged evenly distributed.
- the soft elastic elements 158 are point or blob-like in corresponding formations 163 in the clamping jaws 151 '' 'of the expansion element 116' '' and over the respective peripheral area of a jaw 151 evenly distributed.
- the one used soft elastic plastic has a corresponding non-slip Surface.
- each clamping jaw 151 has a corresponding brake wing 164.
- the designs of the flexible elements 156 to 158 can also according to the embodiment of the expansion element 16 Figure 1 can be provided by the instead of the annular grooves 34 and 35 corresponding formations over the circumference of the expansion element 16 evenly distributed, are arranged.
