Abstract

The invention relates to a stick (10), such as a trekking stick, walking stick, or an umbrella cane or similar, whose lower end (11) is provided with a fixed tip (12). Said stick has a removable cover which is attached to said fixed tip (12) and which can cover an area of the lower end (11) of the stick. The aim of the invention is to create a cover which is suitable for both internal and external use, according to the use of the stick and which is secure against unexpected removal. According to the invention, the cover is provided in the form of an interchangeable tip (20) which is detachably secured in a positive fit to the lower end of the stick (11).

Description

STICK WITH INTERCHANGEABLE TIP

description

The present invention relates to a stick such as trekking, walking, umbrella stick or the like. , according to the preamble of claim 1.

In the case of trekking poles and also ski poles, it is known to put a protective hood on the pole end provided with the fixed hard metal tip, which should prevent the risk of injuries during the transport of the poles and also when handling in the sales shop. Such protective hoods are not suitable for normal use because they are relatively thin-walled. In addition, these protective hoods, since they are only attached more or less loosely, would not hold in the long run, in particular because they are not secured against being pulled off the fixed tip.

The object of the present invention is therefore to provide a stick of the type mentioned, the lower end of which can be provided with a removable hood which is suitable for use both indoors and outdoors in the relevant applications of the stick and is secured against being pulled off ,

To achieve this object, the features specified in claim 1 are provided for a stick of the type mentioned.

The measures according to the invention ensure that the stick can be provided with an interchangeable tip which can withstand essentially the same forces and forms of use as the existing stationary tip. The interchangeable tip can be used where the stationary tip, for example indoors O-

Adhesive connection is possible.

The features according to claim 6 or 7 take into account the intended use, for example hiking or walking in the first case and inline skating or cross-country skiing in the second case.

With the features of claim 8, a defined application of the interchangeable tip to the end of the stick is achieved, while at the same time securing against loosening can be achieved.

Further details of the invention can be found in the following description, in which the invention is described and explained in more detail with reference to the embodiment shown in the drawing. Show it:

Figure 1 in a partially sectioned and longitudinally sectioned representation of the lower end of a stick with an interchangeable tip and

2 shows a representation corresponding to FIG. 1, but with the interchangeable tip removed and only shown in view.

The stick 10 shown in the drawing only with its lower end 11 can be, for example, a trekking stick, a ski stick, in particular cross-country stick, a walking stick, an umbrella stick or the like, each in one-part or multi-part telescopic design. Depending on the type of stick 10, the intermediate section and / or handle section (not shown in each case) are or are designed in a corresponding manner.

In the illustrated embodiment, the lower end 11 of the stick is in use with a tip 12, in particular

The tip 12 is received while an adjoining intermediate region 24 tapers conically to the inner region 23 and is designed to match the corresponding conical intermediate region 15 of the stick end 11. An internal thread 25 adjoins the conical intermediate region 24, which fits screwably over the external thread 16 of the stick end 11. A larger-diameter end region 26 of the inner recess 22 surrounds the smooth cylindrical region 17 and the annular collar 18 of the stick end 11 and, when the interchangeable tip 20 is screwed on, lies with its annular face 27 on the corresponding annular surface 28 of the conical collar 19.

In addition to the fastening sleeve 21 made of hard material, the interchangeable tip 20 has a stressing element 31 which engages over a partial area of the free end of the fastening element 21 and is firmly connected to the latter. The stress element 31 is preferably made of an elastic plastic, which on the one hand can be subjected to abrasion resistance and on the other hand has a non-slip surface. The stress element 31 can, for example, be made of a plastic that is suitable for spraying the stress element 31 onto the tough-hard plastic or polyamide of the fastening element 21. In the exemplary embodiment shown, a positive connection is additionally provided for securing the stressing element 31 axially from the fastening element 21. For this purpose, the fastening element 21 is provided at its end projecting beyond the blind hole inner recess 22 with an annular groove 29 into which a corresponding annular shoulder 32 engages on the inner surface of the recess 33 of the stress element 31, for example sprayed on. The stress element 31 has longitudinal recesses 34 on the outer circumference side, which contribute to a grip when screwing the unscrewable tip 20 on and off the stick end 11. The free end of the stress element 31 is
