Abstract

A handle for ski sticks and the like provided with a wrist strap. The wrist strap is attached to the stick handle by a first connecting element fixed at the wrist strap and a second connecting element lodged at the ski's stick handle, which are interlocked. To insure that the connection between the stick handle and the wrist strap is disengaged automatically only in case of danger and no inopportune releasing occurs, a flexible releasing device is installed, which holds one of the connecting elements at the interlocked position and yields only when the wrist strap is pulled in the same direction, a direction with a force component running longitudinally in the stick from its tip toward the handle, so that the second connecting element held together by the releasing device can be disengaged from its interlocked position.

Description

Stick handle with wrist strap

DESCRIPTION

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

Commercially available ski poles with hand straps fixed in the stick handle are relatively cumbersome to handle if, as in alpine skiing when driving a lift, it is necessary to frequently have to take your hands out of the hand straps. For this reason, so-called "epee handles" were developed that no longer have hand straps. A disadvantage of these handles is that they do not give the skier sufficient support and the Stick is immediately lost when released.

In a stick handle designed according to the preamble of claim 1 and known from DE 28 08 549 AI, the first connecting element is fork-shaped at its end applied to the wrist strap and can be latched via a retaining pin which is held in the stick handle recess which is open at the top. A disadvantage of this construction is that the reattachment of the first connecting element to the stick handle after a safety release is connected with essentially the same amount of force that is necessary for the safety release; in other words, reconnecting is cumbersome and time-consuming. In addition, with this construction there is the possibility of safety release not only in the longitudinal direction of the stick, but also in a direction transverse to the stick handle, which is not desirable. There is no possibility of deliberately loosening the wrist strap from the stick handle without substantial effort.

In the case of a stick handle known from DE 78 04 390 Ul, the connecting element between a stationary stick handle end plate and an insert held in the stick handle can be releasably latched in such a way that the insert points in a direction pointing towards the tip of the stick is compliant. This essentially results in the disadvantages mentioned above, the triggering direction in particular being essentially opposite to that which is essential for a safety triggering.

Another known stick handle according to DE 78 08 851 U1 uses a hinged lid on the end face of the handle, which is opened by pulling on the hand strap, whereby a free end of the hand strap is released. Here it is tedious to thread the hand strap again after a safety release and to fix it under the lid to be closed and to thread the glove back into the strap.

The object of the present invention is therefore to provide a pole grip for ski poles, hiking poles, trekking poles or the like of the type mentioned, in which the reconnection of the wrist strap and pole grip after a safety release, regardless of the size of the release force with minimal insertion force, in a simple and quick manner can be done and he offers at the same time a deliberate release of the wrist strap from the stick handle without significant effort.

To solve this problem, the features specified in claim 1 are in a stick handle of the type mentioned intended .

The measures according to the invention ensure that after a safety release, the first connecting element connected to the hand strap can be quickly and easily snapped into the stick handle or between the handle head face and the second connecting element. The effort required for this is low, since it only depends on the corresponding spring force on the second connecting element. In contrast, the force required for the safety release depends on the setting of the resilient release plate. In contrast to the known cover solutions, a resetting of the release plate is ensured in the subject of the application due to the elastically flexible release plate, so that the stick handle is always ready for the first connecting element to snap back into place. No further measures are necessary for this. In addition, in the stick handle according to the invention, the wrist strap can also be released from the stick handle by simply pressing the actuating element.

An advantageous embodiment of the connecting elements is the subject of claim 2. If the first connecting element has a latching lug that engages behind the second connecting element, the triggering means must Only release the trigger until the catch is released. The first connecting element can then be pulled out of the recess.

A preferred storage of the trigger means is given with the features according to claim 3. When the hand strap is subjected to an upward tensile load, the release means can be pivoted about the axis which is advantageously arranged according to claim 4, as a result of which the latching between the first and second connecting element is released.

Advantageously, according to claim 5, the part of the plate to be pivoted rests on a resilient element, so that the compressibility of the resilient element ultimately determines the tensile force that is necessary for triggering. To determine this tensile force, the features according to claim 9 can alternatively be provided.

Claims 10 to 17 describe constructive alternatives of the arrangement of triggering means and actuating element for central or lateral deliberate triggering, of which the latter is the ergonomically preferred.

If the stick handle according to the invention also used should, if a release is not desired even in falls, for example on ski tours in which the user often moves in rough terrain and deep snow and the ski pole must not be lost in any case, the release means according to claim 18 can be locked by a locking device. The stick then always remains connected to the user's hand.

If the wrist strap is incorporated into a glove, the risk of the wrist strap being lost is reduced.

Further advantageous embodiments result from the features of the other subclaims.

characters

17A to C, an actuator of the stick handle according to FIG. 14, which is integral with the second connecting element, in front view, in longitudinal section or in plan view. A stick handle 10 shown in FIGS. 1 and 2 according to a first exemplary embodiment has a base body 12 which, for example, consists of an injection molded part made of plastic. The base body 12 can be provided with a covering 14 made of material that is easy to grip. The pole grip is attached to a pole 16 of a ski pole, hiking pole, trekking pole or the like.

The stick handle 10 has a recess 18 in the side of its upper handle end piece, in which a hand strap 20 is fixed. For this purpose, the wrist strap 20 is firmly connected to a first connecting element 24 via a securing pin 22 (FIG. 2). The first connecting element 24 can be inserted into the recess 18 and has a latching lug 26 which, in the inserted state of the first connecting element, engages behind a latching edge 28 (FIG. 4) of a second connecting element 30 in a form-fitting manner.

The second connecting element 30 is preferably mounted so as to be resiliently movable in the longitudinal direction of the stick. For this purpose, a sleeve 32 is pressed into a recess 34 which also receives the cane tube 16, which rests on the cane tube 16 in the inserted state and is thereby fixed. A resilient means 36, for example a helical spring, is accommodated in the sleeve 32, which means on the one hand in the sleeve 32 and on the other hand is supported on an underside 38 of the second connecting element 30. So that the spring travel is limited at the top, a locking nut 40 is screwed onto a rod 42 which passes through the helical spring 36 and the sleeve 32 and is connected to the second connecting element 30. The rod 42 is part of an actuating member 44 which is accessible from the handle head face 48 via an actuating button 46. The second connecting element 30 is preferably sprayed onto the rod 42. The second connecting element 30 is thus axially movable, resiliently mounted in the stick handle 10 and can be moved downward in the axial direction via the actuating member 44 until the underside 38 touches a shoulder 50 of the sleeve 32. After releasing the actuating element 44, it is moved back together with the second connecting element 30 via the spring 36 into the starting position shown in FIG. 2. By depressing the actuator 44, the locking between the first and second connecting elements 24 and 30 can be released. The wrist strap 20 can be separated from the stick handle 10. The engagement or release path can be adjusted by turning the lock nut 40.

In a preferred embodiment of the first and second connecting elements 24 and 30, the second connecting element 30 has a bevel on its upper side 52, on which a likewise bevelled surface 54 of the first connecting element is guided when the first connecting element 24 is inserted into the recess 18, so that the second connecting element 30 can be moved downward without tilting against the spring force of the spring 36 and the first connecting element 24 is clean can snap into place. To make it easier to insert the first connecting element 24, it has rounded portions 56 and 58 and further bevels 60 and 62 on its end face (FIGS. 2, 5 and 6). In the end region, the first connecting element 24 has a slot 64, in which the rod 42 of the actuating element 44 is located in the inserted state.

In Figures 11 to 13 is a second

Embodiment of a stick handle 110 with the first and second connecting elements 124 and 130 shown. In this exemplary embodiment, the rod 142 of the actuating member 144 is approximately as large in diameter as the second connecting element 130 and has a slot 118 through which the first connecting element 124 can be passed. The locking lug 126 engages positively behind a locking edge 128 in turn of the second connecting element 130 or the rod 124 of the actuating member. In order to be able to insert the first connecting element 130 quickly and easily, an insert is required 166 is provided, which has a funnel-like opening 168, the funnel opening opening into the slot 118.

According to the invention, a flexible trigger means 70 or 170 is provided, by which one of the connecting elements 24, 30 or 124, 130 is held in the latched position and only when the hand strap 20 is subjected to tensile load in one direction with a force component running in the longitudinal direction of the stick, the force component thereof Direction from a stick tip to the stick handle points, ie according to FIGS. 1 and 2 or 11 upwards, so that the connecting element 24, 30 or 124, 130 held by the release means 70 or 170 can be brought out of its locked position.

In the first exemplary embodiment according to FIGS. 1 to 10, the flexible triggering means 70 is formed by a cover 72 which forms a side 74 of the recess 18 which faces the handle head end face. 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, as it were, opened upward, so that the first connecting element 24 is no longer held in the locked position (FIG. 2) and can be removed from the stick handle 10 without depressing the actuating member 44. Part 80 of plate 76 rests on a resilient element 82 which is compressed when the plate 76 is pivoted in the direction of arrow 83. In a simple variant shown in FIG. 2, the spring-elastic element 82 is formed from a cushion made of elastic material.

In a variant shown in FIG. 7, the resilient element 82 is formed by a helical spring 84, the resilient force of which can be adjusted in that the spring 84 can be pre-compressed by a grub screw 86 screwed into the plate 76.

When there is tensile load on the wrist strap 20 in one direction with a force component running in the longitudinal direction of the stick, the direction of which points from the tip of the stick to the stick handle, i.e. is directed upwards according to FIGS. 1 and 2, the plate 76 becomes in the direction of arrow 83 against the resilient force of the resilient element 82 pivoted. If the pulling force on the wrist strap 20 is large enough, the plate 76 is pivoted so far that the first connecting element 24 is raised so far that the catch 26 no longer engages behind the second connecting element 30. The wrist strap 20 with the first connecting element 24 then comes free from the stick handle 10. This release mechanism is further supported by the fact that when the tensile load on the wrist strap is upward, not only can the release means 70, that is to say the plate 76, give upward, but also a slight rotation of the first connecting element 24 can occur, so that the second connecting element 30 thereby is pressed down slightly, which still supports the unlatching, so that the plate 76 only has to be pivoted slightly.

In a variant not shown, the resilient element 82, the restoring force of which is adjustable, is formed by a cushion wedge made of elastic material, which is slidably mounted between the part 80, the plate 76 and the base body 12 along a bevel of the base body. The cushion wedge can be moved, for example, via a thread, whereby the compression properties and thus the restoring force and thus the release force can be adjusted continuously.

In a further variant of the invention, not shown, the triggering means 70 can be formed by the stick handle material, which must then be correspondingly flexible in the area of the handle head end face 48, in order to move upward in the case of tensile loads on the wrist strap 20 to be able to yield, so that the first connecting element 24 unlocks. In a further alternative, it would be conceivable for the cover 72 to be held by, for example, straps or Velcro strips, which open when subjected to a corresponding load. It would also be possible to fix the cover 72 by means of a non-positive connection.

It goes without saying that the triggering means 170 in the second exemplary embodiment according to FIGS. 11 to 13 can be designed in accordance with the aforementioned triggering means 70.

In a further embodiment of the invention, the stick handle has a locking device 88, by means of which the triggering means 70 or 170 can be locked. The locking device 88 comprises a locking pin 90 which can be inserted into a bore 92 made in the stick handle and into a bore 94 of the release means 70 aligned with this bore 92 (FIG. 3).

In an embodiment of the locking device 88 shown in FIGS. 8 and 9, the locking pin 90 can be displaced via a slide 96 between a release position and a locking position shown in the figures. The slide is accessible from the handle front face 48 and can therefore be used seized stick handle 10 can be easily operated with the thumb. In an alternative embodiment, a rotary mechanism for the locking device would be conceivable instead of a slide.

The hand strap according to FIG. 10 is designed so that the stick handle 120 according to the invention with the hand strap 20 is convenient and easy to use. The wrist strap 20 comprises a loop part 100 which tightly encloses the wrist and which can be changed in its circumference via Velcro fasteners u. On the inside of the hand, the loop part 100 is widened, from which a connecting part 102 extends, which is connected at its free end to the first connecting element 24 or 124. Furthermore, the first connecting element 24 or 124 is connected to a tension element 104 which can be connected via the back of the hand to the loop part 100 encompassing the wrist, preferably via Velcro fasteners. The tension element 104 preferably consists of an elastic material, for example an elastic band or the like. In the applied state of the wrist strap 20, the first connecting element 24 or 124 extends finger-like away from the palm of the hand, so that when the stick handle 10 is gripped, the first connecting element 24 or 124 can be inserted into the recess 18 or 118 without further manipulations and there due to of the spring-mounted second connecting element 30 or 130 automatically locked. In one embodiment, the wrist strap 20 can be incorporated into a glove 106. The user of the stick handle according to the invention then only has to put on the gloves and grip the stick handle 10. The glove 106 with its first connecting element 24 or 124 then automatically locks with the stick handle 10. This ensures a connection of optimal functionality and simultaneous safety.

The stick handle 210 shown in FIGS. 14 to 17 according to a third exemplary embodiment also has a base body 212 made of, for example, an injection molded part made of plastic. The base body 212 is also provided with a covering 214 made of material that is easy to grip.

While in the case of the stick handles 10 and 110 of the first and second exemplary embodiment, the actuating member 44 and 144 is arranged and designed in such a way that an actuating button 46 and 146 is arranged axially in the center with respect to the stick handle and the stick tube 16 and an opening 47 and 147 penetrates in the cover 72 of the release means 70 or 170 and protrudes somewhat on the end face 48 or 148 of the handle head, in the case of the stick handle 210 of the third exemplary embodiment the actuating element 244 is designed in this way and with respect to the cover 272 of the Trigger means 270 arranged such that it can be actuated from the handle head end face 248 provided with two openings 247, 247 'on both sides of the trigger means 270.

For this purpose, the actuating member 244 has a U-shaped base 243, on each of which two upwardly projecting parallel legs an actuating button 249 or 251 is integrally formed and the base or connecting leg 245 forms the second connecting element 230. The base leg 245 is arranged in accordance with FIG. 17B in a lower rear area. The recess 218 for the second connecting element 224 is formed between the two upright legs of the U-shaped base 243. As can be seen in FIG. 14, the first connecting element 224 has a locking lug 226 and the second connecting element 230 has a corresponding undercut locking edge 228. It can also be seen here that the recess 218 is not only of the two upright legs of the U-shaped base 243 but is also limited by the base body 212 and by the cover 272 of the release means 270.

As in the first exemplary embodiment, the wrist strap 220 is held in the first connecting element 224. Furthermore, as in the first exemplary embodiment, the cover 272 of the Trigger means 270 pivotally mounted about an axis 278, wherein the axis 278 is arranged offset in height near the inner end of the recess 218. In contrast to the first exemplary embodiment, the rear side 280 of the cover 272 is provided with an undercut nose 281, which is supported on an upstanding part 285 of the base body 212. The nose 281 is designed to be resilient, so that when the tensile load is applied, the cover 272 swings forward about its axis 278 in accordance with the arrow 283, the nose 281 yielding in an elastically resilient manner; after relief, the resilient nose 281 causes the cover 272 to be returned to its starting position shown in FIG. 14.

The second connecting element 230 or the base leg 245 of the U-shaped base 243 of the actuating element 244, which is identical therewith, is provided on the underside 238 with a blind hole recess for receiving one end of an axial coil spring 236, and the other end in a pot-like recess protruding into the pole tube 216 of the base body 212 is held and guided. The corresponding movement limitation of the second connecting element 230 corresponds to that of the first exemplary embodiment. The two actuation buttons 249 and 251 on the U-shaped base 243 are on the inside along the boundary surfaces of the cover 272 of the release means 270 and on the outside along the boundary of the remaining cover of the handle head face 248. Since the two actuation buttons 249 and 251 are connected to one another in terms of movement, one or the other actuation button can be pressed to release the first connection element 224 from the stick handle 210.

According to the partial figures 17 A and B, the actuation buttons 249 and 251 are provided with a soft layer 253 along their upper or actuation surface. It goes without saying that this actuating surface can instead also be designed as a hard surface.
