ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a ski pole grip, in particular for cross-country poles, having a wrist strap, which is releasably lockable to the pole grip via a first connecting element that is fixed to the wrist strap, and a second connecting element cooperating with the first connecting element, provided in a pole grip recess and movable counter to resilient bearing by means of an actuating member that is accessible in the region of the grip head.
In one such pole grip, known from German Patent DE 196 36 852 C1, the pole grip recess is accessible from a circumferential side for the first connecting element solidly connected to the wrist strap, and is covered on the face end of the grip head by a release cap and the actuating member. The actuating member is movable in the axial direction of the pole grip and is coupled with the second connecting element for the sake of axial motion of the second connecting element. In this known pole grip, the inlet and outlet of the pole grip recess are accordingly disposed perpendicular to one another, which is appropriate in designing downhill ski poles, in particular, since the pole grips for such poles are typically provided with a slightly curved grip head face end extending substantially perpendicular to the axis of the pole.
OBJECT AND SUMMARY OF THE INVENTION
The object of the present invention is to provide a pole grip of the type defined at the outset whose releasable wrist strap fastening is adapted to the preferably slenderer forms of cross-country ski pole grips and is released in a structurally simpler way.
To attain this object, in a pole grip of the type defined at the outset, the inlet to the pole grip recess into and out of which the first connection element can be introduced and retracted, is disposed in an approximately rectilinear alignment with the outlet of the pole grip recess, in whose region the actuating member is actuatable.
By the provisions according to the invention, because of the approximately rectilinear alignment, a structurally simpler capability of releasable locking of the two connecting elements inside the pole grip recess is obtained. Moreover, the face end of the grip head of the cross-country ski pole can be designed in a more versatile way.
By disposing the pole grip recess at an acute angle to the longitudinal axis of the pole grip, or of the pole tube connected to it, or by providing the inlet to the pole grip recess on a circumferential region and providing the outlet of the pole grip recess on a leveled grip head end of the pole grip; or protruding the actuating member past the outlet of the pole grip recess, it is attained that the capability of locking the wrist strap in the pole grip does not increase the diameter of the pole grip; that is, the pole grip can be kept very slender. Nevertheless, designing the upper free end of the pole grip is advantageously possible.
Advantageous handling of the release of the locking is obtained if the by forming the actuating member as a lever pivotably supported in the pole grip recess. The actuating lever is disposed on the one hand in such a way that it cannot be actuated unintentionally, yet nevertheless in such a way that one-hand operation is possible.
Advantageous and simple constructive provisions are obtained from the emboding the actuating member as a lever and forming it and the second connecting element as, one piece, or by pivotably connecting the actuating lever between the pivot axis and the outlet of the pole grip recess with a spring, or by providing a spring which is based on an inner wall region of the pole grip and which presses the actuating member against a wall region of the pole grip that defines the outlet of the pole grip recess.
Advantageous features of the connecting elements and their disposition inside the pole grip recess are realized in that the first and second connecting elements are provided with lugs that interests with one another, or in that the first connecting element, in the state in which it is thrust into the pole grip recess is braked on an inner guide face of the pole grip, or in that the inner guide face is provided with a stop.
Further details of the invention can be learned from the ensuing descriptions, in which the invention is described and explained in further detail in terms of the exemplary embodiment shown in the drawing.
