DETAILED DESCRIPTION

(8) FIG. 1a shows a sectioned illustration of an embodiment of a telescoping and/or folding pole 10 according to the invention and FIG. 1B shows a perspective view thereof.

(9) In this embodiment, the telescoping and/or folding pole 10 is intended to be used, for example, as a walking pole and has a handle 17 and a base 18 for this purpose.

(10) The telescoping and/or folding pole 10 contains a first tubular portion 1 and a second tubular portion 2, wherein the first tubular portion 1 is arranged along a specific length in a precisely fitting manner in the second tubular portion 2.

(11) The outer diameter of the first tubular portion 1 corresponds to this end with the exception of a gap dimension to the inner diameter of the second tubular portion 2 so that the first tubular portion 1 can be axially displaced in the second tubular portion when the securing element 4 does not prevent this.

(12) The securing element 4 extends through a radial opening 3 and is resiliently loaded in a radially outward direction by means of a resilient element 8 in the form of a yoke spring.

(13) The second tubular portion 2 is positioned on the portion of the securing element 4 which projects beyond the first tubular portion 1. A pushing-together of the first tubular portion 1 with the second tubular portion 2 is thereby prevented.

(14) Between the first tubular portion 1 and the second tubular portion 2 there is further a cable connection 15 so that an additional pushing-out of the first tubular portion 1 from the second tubular portion 2 is possible only to a limited extent.

(15) The telescoping and/or folding pole 10 thereby has a substantially fixed length and can, as mentioned, be used as a walking pole or the like. In order to reduce the length of the telescoping and/or folding pole 10 so that it can, for example, be stored, the securing element 4 can be uncoupled and the first tubular portion 1 can be pushed into the second tubular portion 2, which will be described below.

(16) To this end, the embodiment is illustrated in four phases of the uncoupling of the securing element 4.

(17) FIGS. 2A and 2B show the embodiment in the still-coupled state of the securing element 4 as a perspective illustration and a sectioned illustration. FIGS. 7A and 7B each show a cut-out from FIGS. 2A and 2B in the region of the securing element 4. FIGS. 6A and 6B show the same subject-matter as FIGS. 7A and 7B from a slightly different perspective.

(18) FIGS. 3A and 3B show the first step for uncoupling the securing element 4 as a perspective illustration and a sectioned illustration. FIGS. 8A and 8B each show a cut-out from FIGS. 3A and 3B in the region of the securing element 4. In this first step, the first tubular portion 1 and the second tubular portion 2 are pulled slightly apart so that the second tubular portion 2 moves out of the recess 5 in the securing element 4. With respect to the recess 5 and the engagement of the second tubular portion 2, reference may be made to FIGS. 11A to 11F.

(19) The securing element 4 can now be pressed counter to the action of the resilient element 8 into the first tubular portion 1. This is shown in FIGS. 4A and 4B as a perspective illustration and a sectioned illustration. FIGS. 9a and 9b show in each case a cut-out from FIGS. 4A and 4B in the region of the securing element 4. A chamfer 12 which is directed in the direction of the second tubular portion 2 on the securing element 4 facilitates this for the user.

(20) It should be mentioned that the radial opening 3in this embodiment a holecan be clearly seen in FIG. 9A.

(21) The actual telescoping action is now possible, that is to say, by the first tubular portion 1 being pushed into the second tubular portion 2. This is shown in FIGS. 5A and 5B as a perspective illustration and a sectioned illustration. FIGS. 10A and 10B each show a cut-out-out from FIGS. 4A and 4B in the region of the securing element 4.

(22) As can be seen in FIG. 10B, the resilient element 8 further loads the securing element 4 so that the securing element 4 again automatically extends through the radial opening 3 as soon as the first tubular portion 1 has been pulled to a sufficient extent out of the second tubular portion 2 again. The telescoping and/or folding pole 10 can thereby automatically be moved again into the starting state illustrated in FIGS. 1A and 1B.

(23) In the telescoped state, which is illustrated, for example, in FIG. 10B, the rail opening 3 further retains the securing element 4 and the resilient element 8 in the correct axial position.

(24) As already mentioned, the first tubular element 1 may be adjoined, for example, by a third tubular element which is connected by means of the cable connection 15 or in a telescoping manner to the first tubular element 1.

(25) In FIGS. 11A to 11F, the embodiment is in various views in the region of the securing element 4. In the drawings:

(26) FIGS. 11A and 11B show lateral illustrations, FIG. 11C shows the detail A from FIG. 11B, FIG. 11D shows a sectioned illustration (see the plane drawn in FIG. 11F), FIG. 11E shows the detail C from FIG. 11D and FIG. 11F shows a horizontal section.

(27) It can be seen that the sleeve 16 of the second tubular portion 2 engages in the recess 5 of the securing element 4. In this embodiment, the recess 5 is in the form of a groove.

(28) The groove has a groove base 11, a radially inwardly directed face 6 as a groove flank and a radially outwardly directed face 7 as another groove flank. In this regard, reference may also be made to FIGS. 13a to 13I.

(29) An end face 14 of the sleeve 16 of the second tubular portion 2 is positioned on the groove base 11 and prevents the first tubular portion 1 from being pushed together with the second tubular portion 2.

(30) The radially inwardly directed face 6 prevents the securing element 4 from being pressed in with the resilient loading being overcome as long as the securing element 4 engages in the groove.

(31) As a result of the resilient loading of the securing element 4, the radially outwardly directed face 7 applies a radial securing force to the portion of the second tubular portion 2 which engages in the groove (in this instance, a portion of the sleeve 16).

(32) FIGS. 13A to 13I show the securing element 4 as different perspective views and sectioned views.

(33) Particularly FIG. 13E clearly shows that the recess 5 has a bend. This bend is configured in such a manner that the second tubular portion 2 can engage precisely in the recess 5, although the second tubular portion 2 is itself curved (cf. FIG. 11E).

(34) Particularly FIG. 13D shows the mentioned chamfer 12 which simplifies the pressing-in of the securing element 4 when the first tubular portion 1 and the second tubular portion 2 has to be retained in the slightly pulled-apart position which is shown in FIGS. 3A, 3B, 8A and 8B.

(35) Particularly FIGS. 13g and 13H show that the radially inwardly directed face 6 and the radially outwardly directed face 7 are not completely parallel with the center axis of the first tubular portion 1 and the second tubular portion 2. This facilitates simple and rapid engagement and extraction of the second tubular portion 2 into or from the recess 5.

(36) Particularly FIG. 13D shows that the securing element 4 has guide faces 19 which guide the securing element 4 in the radial opening 3 of the first tubular portion 1 in such a manner that rotations of the securing element are prevented and the chamfer 12 always remains orientated in the desired direction.

(37) In addition to the embodiment shown in this instance, other embodiments are of course possible. For example, the second tubular portion 2 could be configured without a sleeve 16 and thus engage directly in the recess 5.

(38) In place of yoke springs, for example, conical springs or other springs which are adapted to the inner geometry of the first tubular portion could also be used.

(39) Additional radial openings could also be provided in the second tubular portion 2, wherein the securing element extends through overlapping radial openings. The recess could then, for example, be dual-sided or circumferential. In this manner, a telescoping and/or folding pole according to the invention which can be adjusted in terms of length could be produced. The securing element 4 would then not only inhibit pushing together but also pulling apart the first tubular portion 1 and the second tubular portion 2.
