Ski pole with a shock absorbing arrangement

The invention relates to a ski pole according to the preamble of claim 1. Such a ski pole is known from AT-PS 326 016, Fig. 19. There the tip of the pole is cushioned by two leaf springs, which yield when loaded and are therefore shock-absorbing works. However, the arrangement shown there is cumbersome, little secured against corrosion, and increases the weight of the pole considerably.

AT-PS 304 332 shows a similar arrangement. There, too, a compression spring is provided in the area of the pole tip, which When the stick is not in use, push a cover sleeve over the tip of the stick, thereby protecting it from injuries. With such a Arrangement, it is also known from US Pat. No. 2,596,733 to arrange the spring in the area of the stick handle, but then the Stick very heavy and unwieldy.

Therefore it is an object of the invention to provide a shock absorbing To create a ski pole which at least partially eliminates the above-mentioned disadvantages.

This object is achieved according to the invention by what is stated in the claim 1 specified measures. The result is a ski pole whose weight is only slightly increased and which is shock-absorbing Spring link is well protected against corrosion.

Further details and advantageous developments of the invention result from what is described below and in the

embodiment shown in the single figure, as well as from the subclaims.

The single figure shows a longitudinal section through the upper part of a ski pole according to the invention. In the case of the Embodiment consists of the actual stick section in the usually from an aluminum tube 10, but of course a fiberglass rod or the like could also be used will.

In the upper end of the stick 11 is a plastic molding 12 attached, e.g. by gluing or by mechanical deformation of the stick end 11. This shaped piece 12 has at the top an extension 13 for receiving the lower end of a coil spring 14, which serves as a spring member to absorb shocks. The fitting 12 extends over a considerable length in the tube 10, e.g. preferably as shown to about 4 - 5 cm. It has a cylindrical guide recess in its center 15 with a diameter in the range of preferably 6 ... 8 mm, and adjoining this below a recess 16 with a hexagonal Cross-section. The cylindrical guide recess 15 has a preferred length of about, for example, as shown 3 - 5 cm.

The upper stick end 11 is guided in an axially displaceable manner Recess 18 of a stick handle 19 of known shape. Of the Handle 19 consists in the usual way of a plastic, e.g. PVC or polyethylene, and is preferably made of transparent

qeducated. For the guide of the upper stick end 11 can in hand aluminum or hard plastic qriff 19 a tube from / injected, as indicated at, but it has been shown that the axial Guiding in the plastic of the handle 19 is completely sufficient, especially if the plastic is set a little harder, as is readily apparent in the craftsmanship.

In the upper end of the recess 18 there is an abutment 24

attached, e.g. by pressing in or by gluing. It can be made of plastic or greased aluminum.

It has at its lower end an extension 25 for receiving the upper end of the coil spring 14. Furthermore, it is with a Provided threaded hole 26 into which a screw bolt 27 is screwed with its threaded end and additionally glued is to prevent rotation of this screw bolt 27 securely. The screw bolt 27 extends through the interior of the helical spring 14 and the cylindrical recess 15 to the hexagonal recess 16 in which its hexagonal head 28 is axially displaceable, but non-rotatable, out. In this way the handle 19 is in fact relative to the tube 10 in FIG Slidable in the longitudinal direction, but not rotatable relative to the tube 10. Naturally, this is particularly important for cross-country ski poles, in which the tip of the stick must have a certain angular position relative to the handle 19. The hexagon head 28 at the same time acts as a stop to prevent the handle from being torn off the stick 10. The bolt 27 can also be screwed and be secured by a lock nut. The smooth cylindrical part of the screw bolt 27 is in the cylindrical recess 15 is guided with little play, e.g. preferably with a play of the order of magnitude of 0.05 mm, i.e. that the diameter of the bolt 27 is, for example, 6.0 mm and the diameter of the recess 15 is 6.05 mm. This causes serving as a guide member screw bolt 27 a longitudinal guide of the handle 19 on the stick 10 and relieves the lateral guidance. The fitting 12 can be made of a special dimensionally stable polyamide, which also has the required good sliding properties. The one serving as a spring link Helical spring 14 itself is a standard spring. Alternatively, a spring with progressive spring characteristics could be used, e.g. a conical spring, or a spring made of a suitable elastomer.

Instead of a round bolt 27, an out-of-round bolt could naturally also be used, e.g. a square, which is in a complementary non-circular recess 15 out. will. In this case the head 28 can be round. The shown Solution is preferred, however, since standard parts can be used with it, e.g. a standardized hexagon screw 27, so that

the production is possible very inexpensively.

The lateral recess 31 on the obscure end of the handle is used to Attachment of a handle loop - not shown. This is by means of a '- screw from - not shown Type wood screw clamped into a recess engages in the abutment 24 and thereby pulls it upwards. The abutment 24 and the upper one are expedient The end of the recess 18 is slightly conical, as the drawing shows, so that when this screw is tightened a conical pressing takes place, which holds the abutment 24 in a rotationally secure manner.

For better visual control, the screw bolt 27 is expediently either chrome-plated or silver-colored galvanized, while the coil spring 14 is galvanized in gold. The function can then pass through the transparent handle 19 of the spring member 14 can be controlled excellently.

During assembly, the abutment 24, the spring and the shaped piece 12 are first put together. Then the screw bolt 27 attached in the manner shown, whereby the parts 24, 14 and 12 are connected to form a structural unit. This construction f The unit is then attached to the upper end of the stick 11, e.g. by gluing. Then the stick 10 with this ^ Unit attached in handle 19. So the assembly is extraordinary easy, and the structural units can be pre-assembled and pre-adjusted to a certain preload before they are built in. Such a possibility is not available in any of the known solutions according to the prior art given, i.e. these known solutions were far more complicated and cumbersome to assemble, while in the case of the invention e.g. also the replacement of a damaged handle 19 without further is possible.
