DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a stick, such as a ski pole, a walking stick or the like with a pole grip and a pole tube, whose length can be changed, as well as with an adjustment device including a hinge by means of which at least one grip area of the pole grip can be fixed in an angled away position with respect to the pole tube.
BACKGROUND OF THE INVENTION
Ski poles, in particular for alpine skiers, wherein the pole tube is bent in the upper area close to the pole grip, so that when the ski pole is pushed in, it can be held with a natural, unstrained position of the wrist, even when it is pushed in with its tip relatively far ahead, are known.
In order to be able to individually adjust the angle between the ski pole and the pole grip, a ski pole with an adjustment device is known from published German application, DE 44 40 343, by means of which the pole grip can be fixed in an angled away position with respect to the pole tube. Further than that, the length of the ski pole disclosed in the noted publication can be changed, so that it can be adapted to various body sizes and can be shortened to a shorter size for better stowing in a backpack or the like.
However, it is disadvantageous in connection with the known ski pole in that the stowing size, i.e. the minimum length of the ski pole, is considerably larger than with known ski poles whose length can be changed in a telescopic manner, because a lower portion of the ski pole can only be pushed into the upper pole tube as far as the hinge of the adjustment device. Because of this, either the stowing size is increased, or the pole must be divided several times for achieving a shorter stowing size, but this is correspondingly disadvantageous in regard to cost.
SUMMARY OF THE INVENTION
It is an object of the present invention to make an improved pole available, wherein at least one grip area of the pole grip can be fixed in place in an angled away position with respect to the pole tube, but can nevertheless be shortened to a short stowing size.
This object is attained by a pole which has two partial elements which are connected by means of an adjustment device, which adjustment device is arranged outside of the pole tube.
If the pole tube has two partial elements connected via the adjustment device, and the adjustment device is arranged outside of the pole tube, the pole tube can remain hollow on the inside even in the area of the hinge. If the partial elements connected by means of the adjustment device are aligned flush, it is possible to push in a further pole tube in a telescopic manner into the pole tube constituted by the partial elements and the hinge. The pole in accordance with the present invention can then be telescopically pushed together to a stowing size reduced a maximum amount, which corresponds to that of known telescopic ski poles whose grip, however, cannot be angled away with respect to the pole tube. After pulling out the telescopic pole tube elements, at least the grip area of the pole grip can be fixed in an angled away position with respect to the pole tube by means of the adjustment device.
An advantageous arrangement of the hinge with respect to the individual tubes of the pole tube results in that the outer tube has two partial elements and when the two partial elements are aligned in a straight line, the inner tube can be pushed into the upper one of the two partial elements through the hinge.
One of the two partial elements has an extension element which has laterally projecting shaft pins constituting a hinge shaft, which are received by a fork-shaped receiving element provided on the other partial element. With this a simple and stable embodiment of the pole in accordance with the present invention, wherein the pole can be angled away in a plane defined by the shaft pins results.
So that the partial elements of the pole tube connected by means of the adjustment device do not fall apart when loosening the adjustment device for adjusting the angle, it is provided in an embodiment of the present
