BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a system for securing a ski pole to the hand of a skier. The invention also relates to a ski pole which is adapted and intended for use in a system of the invention.
2. Description of the Background Art
In cross-country ski poles, the attachment between the hand and a handgrip is established by means of one or more loop-type straps wrapped around the hand. It has also been proposed that the ski glove be secured to a handgrip by means of straps fitted inside the glove (patent application FI-893528). This requires a specially designed glove, in addition to which the attachment between the glove and the handgrip is structurally inconvenient and difficult to release.


SUMMARY OF THE INVENTION

An object of the invention is to provide an improved assembly including a ski glove or a hand-wrapping harness strap and a ski pole, wherein the locking between the hand-wrapping harness strap or the glove and the handgrip is readily claspable and releasable and which provides a good grip and control of the ski pole even when the finger-hold of the handgrip is released. In cross-country skiing, this situation occurs at the end of a thrust when the hand is in a backward position and the forward motion of a ski pole is about to commence.
This object is achieved by means of a system set forth in the annexed claim 1. The characterizing features for an appropriate ski glove or a hand-wrapping harness strap are set forth in claim 6 and the characterizing features for a ski pole in claim 7. The non-independent claims disclose preferred embodiments for the invention.


BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be described by way of an exemplary embodiment with reference made to the accompanying drawings, in which
FIG. 1 shows a system of the invention applied to a ski glove in a perspective view;
FIG. 2 shows a ski-pole handgrip included in the system with a locking piece disengaged from its position; and
FIG. 3 shows a system according to a second embodiment of the invention applied to a hand-wrapping harness strap.


DETAILED DESCRIPTION OF THE INVENTION

Reference is first made to the embodiment of FIG. 1.
In a web area between the thumb and the index finger, a ski glove 1 is provided with a bracing 3 which is made of an inextensible, tough and break-proof, yet elastic material, such as e.g. polyurethane. The bracing 3 is provided with a lip 4 which is secured as an inlay to an extruded or injection-moulded locking piece 5. The locking piece 5 takes the shape of a wedge or a triangle and can be inserted sideways into a receiving cavity 6, included in a handgrip 2 and having a shape matching that of the locking piece 5, as shown in FIG. 2.
The handgrip 2 is provided with a locking bolt 7, 9, 10, including a press-button element 9 extending from the top of the handgrip and a latching pawl 7 engaging in a recess 8 made in the locking piece 5. The locking bolt can be pressed lengthwise of the handgrip against the force of a spring 11 for releasing the latching pawl 7 from the recess 8 of the locking piece 5. Thus, when the bolt 7, 9, 10 is in a depressed position, the locking piece 5 can be pushed into its position in the cavity 6 or disengaged from the cavity 6.
Designated in the locking piece 5 with reference numeral 12 is an attachment point for the lip 4, wherein the lip 4 is permanently secured. Thus, the locking piece 5 is an integral part of the ski glove 1. The user is free to choose fitting-size ski gloves and proper-length poles. The locking piece 5 does not prevent the ski gloves from being used also in applications other than a combination of the invention.
The lip 4 is as short as possible, virtually without a length dimension, the handgrip 2 coming into contact with the web between the thumb and the index finger. Stiffness of the lip 4 can be used to have an effect on how easily the pole is able to swing as the hand releases its grip during the backward movement. A relatively soft and thick bracing 3 protects th
