Description

The present invention relates to a pole handle for ski poles, hiking poles, trekking poles or the like, with a hand strap, according to the preamble of claim 1.

In a pole handle with a hand strap, as known from DE 196 36 852 Cl, an actuating element accessible from the forehead side is provided for the deliberate release of the hand strap from the pole handle. To do this, it is only necessary to press the actuating element downwards so that the first connecting element connected to the hand strap is released from the pole handle recess. One problem here can be that during the

When ascending or descending on skis, if the user supports himself with the palm of his hand on the front of the pole handle, the actuating element may be inadvertently pressed down and the hand strap may thus be released from the pole handle.

The object of the present invention is therefore to provide a pole handle for ski poles, hiking poles, trekking poles or the like of the type mentioned at the beginning, in which an unintentional release of the hand strap from the pole handle when used while supporting oneself is avoided.

To achieve this object, the features specified in claim 1 are provided in a stick handle of the type mentioned.

The measures according to the invention ensure that the generally pressing support of the user's palm on the front side of the handle head prevents the first connecting element from becoming loose from the pole handle recess.

The features according to claim 2 ensure that pressure on the actuating member simultaneously means pressure with the palm of the hand on the safety button. A preferred embodiment for this results from the features according to claim 3.

According to one embodiment of the present invention, the features according to claim 4 and, in a further embodiment, those according to claim 5 are provided. This immediately secures the first connecting element connected to the hand strap. In other words, even if the actuating member is pressed downwards, the first connecting element remains in its position within the pole grip recess.

According to another embodiment of the present invention, the features according to claim 6 or those according to claim 7 and/or 8 are provided. In this embodiment, pressing the safety button blocks the actuating member relative to the release means, i.e. it cannot be pressed downwards.

The features according to claim 9 and/or 10 ensure that the safety device or safety button is pressed first before the actuating member for releasing the loop from the handle head recess can be actuated.

Further details of the invention can be found in the following description, in which the invention is described and explained in more detail using the embodiments shown in the drawing. They show:

The pole handle 10 shown in the drawing according to two embodiments has a base body 12, which consists for example of an injection-molded part made of plastic. The base body 12 can be provided with a covering 14 made of

be provided with a material that is easy to grip. The pole handle is placed on and over a pole tube 16 of a ski pole, hiking pole, trekking pole or the like.

The pole handle 10 has a recess 18 on the side in the area of its upper handle end piece, in which a hand strap 20 is fixed. For this purpose, the hand strap 20 is firmly connected to a first connecting element 24 via a cross pin 22. The first connecting element 24 can be inserted into the recess 18 and has a first locking lug 26 which, when the first connecting element 24 is inserted, positively engages behind a locking edge 28 of a second connecting element 30.

The second connecting element 30 is preferably mounted in a spring-loaded manner in the longitudinal direction of the pole. For this purpose, the base body 12 is provided with a projection 55 which projects into the pole tube 16 and which is provided with a blind hole open from above, in which a spring-elastic means, for example a helical spring 36, is accommodated, which is supported at one end on the base of the blind hole 56 of the projection 55 and at the other end in a recess in the underside 38 of the second connecting element 30. An actuating member 44 is operatively connected to the second connecting element 30, which is accessible from the handle head front side 48. The second connecting element 30 is thus mounted in the pole handle 10 in an axially movable spring-loaded manner and can be in

axial direction via the actuating member 44. After releasing the actuating member 44, it is moved back together with the second connecting element 30 via the spring 36 into the starting position shown in Figure 1. By pressing down the actuating member 44, the locking between the first and second connecting elements 24 and 30 can be released. The hand strap 20 can be separated from the pole handle 10.

Furthermore, a flexible release means 70 is provided, by which the first connecting element 24 is held in the locked position and which only gives way when the hand strap 20 is subjected to a tensile load in a direction with a force component running in the longitudinal direction of the pole, the direction of which points from a pole tip to the pole handle, i.e. upwards according to Figure 1, so that the first connecting element 24 held by the release means 70 can be brought out of its locked position.

The flexible release means 70 is formed by a cover 72, which forms a side of the recess 18 facing the handle head front side 48. The cover 72 consists of a plate 76, which is pivotally mounted about an axis 78. When the plate 76 is pivoted in the direction of the arrow 83, the recess 18 is opened upwards, so to speak, so that the first connecting element 24 is no longer held in the locked position (Figure 1) and can be released without pressing down the

Actuating member 44 is removable from the pole handle 10. A part 80 of the plate 76 rests on a spring-elastic element 82 which is acted upon when the plate 76 is pivoted in the direction of the arrow and which is formed here by a one-piece metal leaf spring. The one-piece metal leaf spring 82 is arranged in an area which lies beyond the pivot axis 78 with respect to the recess 18.

In the embodiments shown, the actuating member 44 is designed and arranged in relation to the cover 72 of the triggering means 70 in such a way that it can be actuated from the handle head front side 48 provided with two openings 47, 47' on both sides of the triggering means 70. For this purpose, according to Figure 6, the actuating member 44 has a U-shaped base 43, on whose two upwardly projecting parallel legs an actuating button 49 or 51 is formed in one piece and whose base or connecting leg 45 forms the second connecting element 30. The base leg 45 is arranged in a lower, front area as seen in the direction of travel, according to Figure 6B. Between the two upright legs of the U-shaped base 43, the recess 18 for the second connecting element 24 is formed, which is delimited not only by the two upright legs of the U-shaped base 43 but also by the base body 12 and the cover 72 of the release means 70.

The two actuating buttons 49 and 51 on the U-shaped base 43 are guided on the inside along the boundary surfaces of the cover 72 of the release means 70 and on the outside along the boundary of the remaining cover of the handle head front side 48. Since the two actuating buttons 49 and 51 are connected to one another in terms of movement, one or the other actuating button can be pressed to release the first connecting element 24 from the pole handle 10.

The pole handle 10 according to both embodiments has a safety device 60 (Figures 1 and 2) or 60' (Figures 3 to 5), which serves to prevent the first connecting element 24 from being released from the pole handle recess when the user supports himself with the palm of his hand on the handle head front side 48 while skiing and possibly inadvertently presses down one of the actuating buttons 49 and 51 of the actuating member 44. This can be possible if the support is not essentially centered on the top of the cover 72 of the release means 70.

For this reason, the safety device 60 or 60' has a safety button 61 or 61', which is held in a spring-loaded manner in an axial bore 62 or 62' of the cover 72 of the release means 70. The safety button 61 or 61' projects above the top of the cover 72 in the resting state.

In the first embodiment, according to Figure 1, the safety button 61 is connected to an axial safety pin 63 that points towards the first connecting element 24. The through hole 62 in the cover 72 is of stepped design, with a compression spring 65 being arranged between the underside of the safety button 61 and a shoulder 64 of the through hole 62, which concentrically surrounds the safety pin 63. The safety pin has a widening 66 at its end facing away from the safety button 61, which, under the action of the compression spring 65, rests from below against another shoulder of the stepped through hole 62.

When the safety button 61 is pressed, the larger diameter end 66 of the safety pin 63 enters a blind hole 67 in the first connecting element 24 that is coaxial with the through hole 62. This means that even if, in addition to pressing the safety button 61 downwards according to arrow A, the actuating member 44 is also actuated, thereby releasing the first connecting element 24 from the locking connection with the second connecting element 30, the first connecting element 24 still remains in the handle head recess due to the blocking by the safety pin 63. It goes without saying that when supporting the palm of the hand on the front side of the handle head, the safety button 61 is always pressed first and only then, if necessary, the actuating member.

In the embodiment shown in Figures 3 to 5, the safety button 61' acts on a radially movable safety slide in the form of a curved safety leaf spring 63' which is guided in radial slots 68' of the cover 72 of the release means 70. For example, the leaf spring 63' is elongated rectangular with a curved central region so that its ends can be moved in two opposite radial directions. The slots 68' in the cover 72 of the release means 70 are aligned with grooves 69' machined into the two buttons 49 and 51 of the actuating member 44, into which the two ends of the leaf spring 63' engage when the safety button 61' is actuated in the direction of arrow A'. By pressing the safety button 61, the curved area of the leaf spring 63' is brought into a horizontal plane against its pre-tension, so that the ends of the leaf spring 63' can move radially outwards and thus into the groove 69'. This blocks the movement of the actuating member 44 in the direction of arrow A', so that the first connecting element 24 cannot be released from the handle head recess. When the safety button 61' is released, the leaf spring 63' presses the safety button 61' upwards and thus comes free from the grooves 69' of the actuating member 44. It goes without saying that the actuating member 44 according to Fig. 2 in the illustration according to Fig. 6 would still have to be provided with the grooves 69'.

With regard to the embodiment shown in Figures 3 to 5, it is also possible to replace the leaf spring 63' by radially movable slides which can be moved, for example, by means of an actuating surface provided on the safety button 61'.
