This application is the national stage of PCT/EP2003/010157 filed on Sep. 12, 2003 and also claims Paris Convention priority of DE 202 19 461.2 filed on Dec. 10, 2002.
The present invention concerns a pole handle, in particular for cross-country ski poles, nordic walking and alpine poles, comprising a hand retaining device, in accordance with the independent claim, and a ski pole comprising such a pole handle.
In the pole handle disclosed in DE 299 04 591 U1, the pole handle recess extends between an access for the first connecting element of a toggle strap and an opposite outlet opening for the actuating member in an acute-angle arrangement with respect to the longitudinal axis of the pole handle or ski pole. This means that the connecting element fixed on the toggle strap is locked from an inclined direction from below the upper pole handle end and exits in an opposite inclined downward direction. The actuating member and the second connecting member are formed in one piece and are designed as a one-armed lever. Since the pivot axis is disposed at the end of the second connecting member, locking requires great force and is difficult since the locking region is very close to the pivot axis. Moreover, the direction of locking of the first connecting element on the toggle strap to move behind the second connecting element on the one-armed actuating lever requires a movement which is not ergonomic and is extremely difficult to carry out using one hand only.
It is the object of the present invention to design a pole handle of the above-mentioned type which can be detachably mounted to the hand retaining device in a simpler and, in particular with regard to locking, more ergonomic manner.
This object is achieved with a pole handle of the above-mentioned type having the features of the independent claim.
In accordance with the invention, a simple and substantially linear motion in the direction of the longitudinal axis of the pole handle or of the ski pole is sufficient to lock the hand retaining device via its first connecting element thereby simultaneously utilizing counter pressure for the locking process generated by the ski pole itself via its support on the ground. This facilitates and accelerates at least the connecting motion without requiring assistance by the respective other hand.
To insert the first connecting element of the hand retaining device into the longitudinal slit on the pole handle, the latter could have a radial insertion opening in its upper region such that the initial mounting motion is radial and is then followed by an axial motion. However, in the preferred embodiment in which the longitudinal slit, which extends in the first wall delimiting the pole handle recess, can be accessed in a region of the handle head front face, the connecting motion consists exclusively of a substantially axial motion of the first connecting element and of the toggle strap, as the first connecting element is introduced into the longitudinal slit from the upper side of the handle head.
Preferred embodiments of the first connecting element of the toggle strap and its guidance in the longitudinal slit are shown by the features of one or more of the dependent claims.
Preferred constructive embodiments of the actuating member or advantageous handling to release the locking can be extracted from the features of one or more of dependent claims. The actuating lever is thereby disposed to prevent inadvertent actuation thereof while still permitting operation using one hand only for locking and releasing the first connecting element to and from the hand retaining device.
The invention also concerns a ski pole comprising a pole handle in accordance with the features of the independent claim and optionally with at least any one of the dependent claims.
Further details of the invention can be extracted from the following description which describes and explains the invention in more detail using the embodiment shown in the drawing.
The pole handle 10 shown in the drawing in accordance with a preferred embodiment comprises a basic body 12 which is produced e.g. from an injection-molded part of plastic material. The direct handle region of the basic body 12 is provided with a coating 14 of easy-to-grip material which is introduced into a peripheral groove 13 in the basic body 12 (shown in the drawing). The pole handle 10 is attached onto and over a pole tube 16 of a cross-country ski, alpine or nordic walking pole and is rigidly connected thereto (preferably glued or pressed).
The basic body 12 of the pole handle 10 is approximately oval in a lower region 18 and is disposed eccentrically with regard to the longitudinal axis 17 of the pole tube 16 (see
A two-armed lever 41 is pivotably held within the recess 26 via a pivot axle 42 such that it is parallel to the side surfaces 36, 37 of the basic body 12. The pivot axis 42 traverses the recess 26 in an upper rear region and is disposed or held in bores of the two side surfaces 36 and 37. The two-armed lever has an actuating arm 43 which projects outwardly through the opening 27 in the handle head front face 22. A locking arm 44 of the two-armed lever 41 is integral with the actuating arm 43 with the two arms 43 and 44 subtending an obtuse angle. The pivot axle 42 penetrates through the two-armed lever 41 in a region of the locking arm 44 proximate to the actuating arm 43. The locking arm 44 has a connecting element 46 in the form of a nose which terminates close to the front narrow side 21 of the basic body 12 having the longitudinal slit 31 and is provided with an inclined guiding surface 47 at its side facing away from the bottom 28 of the recess 26.
The two-armed lever 41 is loaded by a pressure spring 52 which is designed as a helical spring in the present case and one end of which is supported on the locking arm 44 of the lever 41 within the recess 26 and whose other end is immersed into a bore 54 which extends from the rear narrow side 23 to the inner recess delimitation 25 and is supported on a stop which is formed by a screw 56 inserted from the outside into the rear narrow side 23 of the basic body 12. The pressure spring 52 which extends in a slightly curved manner and is immersed in a blind bore 58 in the locking arm 44 pretensions the two-armed lever 41 into a rest position in which the actuating arm 43 abuts an edge region 48 of the recess 27. The connecting element 46 of the locking arm 44 is thereby proximate to the longitudinal slit 31 in the front narrow side 21. In accordance with arrow A, the two-armed lever 41 can be pivoted about the pivot axle 42, wherein the pivot delimitation is determined on the one hand by the edge region 48 of the recess 26 and on the other hand by the spring path of the pressure spring 52.
In accordance with one embodiment (not shown), the pressure spring 52 is designed as an approximately V-shaped leaf spring whose legs are supported on the inner side on a locking arm 44 and on the opposite side surface 25 of the recess 26 and whose apex faces the edge region 48 of the recess 26.
A toggle strap 11 or another holding device for the hand of a skier, such as e.g. a glove, can be detachably locked to the pole handle 10 (wherein
The connecting element or nose 46 of the locking arm 44 is a counter locking element and serves to lock the connecting element 64 behind the locking arm 44 of the two-armed lever 41. When the connecting element 64 held by the hand strap is introduced into the longitudinal slit 31 from the position in
