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

The invention relates to a pole grip for ski poles, Walking sticks, trekking poles or the like, with one Wrist strap according to the preamble of claim 1.

Commercially available ski poles with a stick grip Fixed hand straps are relatively cumbersome too handle when, as in alpine skiing, when skiing, it is necessary to get your hands out of the wrist straps frequently to have to take out. For this reason, so-called "Epee handles" developed that no longer have wrist straps exhibit. The disadvantage of these handles is that they are Give skiers insufficient support and the Stick is immediately lost when released.

In one according to the preamble of claim 1 trained and known from DE 28 08 549 A1 Stick handle is the first connecting element on his the Hand strap applied end fork-shaped and via a holding pin that is open in the top Stick handle recess is held, lockable. The disadvantage of this construction is that Reinstall the first connector on Stick grip after a safety release with im Essentially the same amount of effort is required for the security release is necessary; in other words, reconnecting is cumbersome and time-consuming. Moreover there is the possibility of with this construction Safety release not only in the longitudinal direction of the pole, but also in a direction across the stick handle, what is not desired. The possibility of the wrist strap from Stick stick consciously and without any major effort solve does not exist.

In a stick handle known from DE 78 04 390 U1 the connecting element between a stationary Stick handle faceplate and one in the stick handle held insert in the way releasably latched that use in a direction pointing to the tip of the stick is compliant. This essentially results in the above mentioned disadvantages, in particular the triggering direction is essentially contrary to that for a Security triggering is essential.

Another known stick handle according to DE 78 08 851 U1 uses a hinged lid on the handle head face, the is opened by pulling on the wrist strap, creating a free end of the wrist strap is released. It's hard here the hand strap again after a safety release to thread and under the lid to be closed fix and put the glove back in the loop to thread.

The object of the present invention is therefore a Pole handle for ski poles, hiking poles, trekking poles or To create the like of the type mentioned, in which reconnecting the hand strap and stick handle a security trip regardless of the size of the Release force with minimal insertion force in simple and can be done quickly and at the same time deliberately loosening the wrist strap from the stick handle without offers significant effort.

To solve this problem are the mentioned type the features specified in claim 1 intended.

The measures according to the invention ensure that after a safety release, that with the wrist strap connected first connecting element quickly and easily in Stick handle or between the handle head face and the second connecting element can be latched. The one for this The effort required is low because it is only from the corresponding spring force on the second connecting element is dependent. In contrast, it is for Security release required force from the Adjustment of the resilient release plate dependent. Different from the known lid solutions in the subject of registration due to the elastic resilient trigger plate a provision of the Trigger plate ensures that the stick handle always for re-engagement of the first connecting element ready. No further measures are necessary for this. In addition, the stick handle according to the invention Hand strap from stick handle also wanted by simple Pressure on the actuator can be released.

An advantageous embodiment of the connecting elements is Subject matter of claim 2. If the first Connecting element has a latch that the second Reaching behind the connecting element, the trigger means to Only release the trigger until the catch is released. The first connecting element can then come out of the recess to be pulled.

A preferred storage of the trigger is with the Features given according to claim 3. With up Directed tensile load on the wrist strap is that Release means around the advantageous according to claim 4 arranged axis pivotable, which causes the locking released between the first and second connecting element is.

Advantageously, according to claim 5, the pivoting part of the plate on a resilient Element on so the compressibility of the the elastic element ultimately determines the tensile force, which is necessary for a release. For determination this traction can alternatively be the characteristics Claim 9 may be provided.

Claims 10 to 17 describe constructive alternatives the arrangement of release means and actuator for deliberate release in the middle or on the side, of which the the latter is the most ergonomically preferred.

If the stick handle according to the invention is also used should be, if a release is not even in the event of a fall is desirable, for example on ski tours where the Users often in rough terrain and in Deep snow moves and the ski pole in no case may be lost, the trigger means according to claim 18 lockable by a locking device. The Storey then always remains connected to the user's hand.

If the wrist strap is incorporated into a glove, the risk of losing the wrist strap is reduced can go.

Further advantageous configurations result from the Features of the other subclaims.

A stick handle 10 shown in FIGS. 1 and 2 according to FIG a first exemplary embodiment has a base body 12 on, for example, from an injection molded part Plastic is made. The base body 12 can with a Cover 14 made of easy-to-grip material. The pole grip is on a pole 16 of a ski pole, Hiking poles, trekking poles or the like attached.

The stick handle 10 has in the area of its upper Grip end piece on the side of a recess 18 in which Wrist strap 20 is set. This is the wrist strap 20 via a locking pin 22 firmly with a first Connecting element 24 connected (Figure 2). The first Connecting element 24 can be inserted into the recess 18 and has a locking lug 26 which is inserted in the State of the first connecting element a locking edge 28 (FIG. 4) of a second connecting element 30 engages positively.

The second connecting element 30 is in the longitudinal direction of the stick preferably spring-mounted. There is a sleeve for this 32 into a recess 34 also receiving the cane 16 pressed in the inserted condition on the cane 16 rests and is thereby determined. In the sleeve 32 is a resilient means 36, for example one Coil spring, which is included in the sleeve 32 and on the other hand on an underside 38 of the second Connection element 30 is supported. So the travel is limited, a lock nut 40 is on a coil spring 36 and sleeve 32 penetrating and rod connected to the second connector 30 42 screwed on. The rod 42 is part of one Actuator 44, which has an actuation button 46 is accessible from the handle head face 48. The second Connecting element 30 is preferably on rod 42 sprayed on. The second connecting element 30 is thus in the Stick handle 10 axially movable, spring-loaded and can in axial direction over the actuator 44 down be moved until the bottom 38 a paragraph 50 of Sleeve 32 touches. After releasing the actuator 44 this together with the second connecting element 30 represented by the spring 36 in FIG Moved back to the starting position. By depressing the Actuator 44 is the latching between the first and second connecting element 24 and 30 releasable. The Wrist strap 20 can be separated from the stick handle 10. The engagement or release path is by turning the Lock nut 40 adjustable.

In a preferred embodiment of the first and second Connecting element 24 and 30 has the second Connecting element 30 has a chamfer on its upper side 52 on which a likewise bevelled surface 54 of the first connecting element when inserting the first Connecting element 24 is guided into the recess 18, so that the second connecting element 30 without tilting slidable against the spring force of the spring 36 downwards is and the first connecting element 24 engage cleanly can. To facilitate the introduction of the first Connecting element 24 has this on its end face Rounds 56 and 58 and further bevels 60 and 62 on (Figures 2, 5 and 6). The first in the forehead area Connecting element 24 has a slot 64 in which the inserted state the rod 42 of the Actuator 44 is located.

In Figures 11 to 13 is a second Embodiment of a stick handle 110 with the first and second connecting elements 124 and 130. In this embodiment, the rod 142 is the Actuator 144 about as large in diameter formed like the second connecting element 130 and has a slot 118 through which the first Connecting element 124 can be passed through. The latch 126 positively engages behind a locking edge 128 of the second connecting element 130 or the rod 124 of the Actuator. Around the first connecting element 130 It is an effort to be able to introduce it quickly and easily 166 is provided which has a funnel-like opening 168 having the funnel mouth into the slot 118 flows.

According to the invention, a flexible trigger means 70 or 170 provided through which one of the connecting elements 24, 30 or 124, 130 is held in the locked position and only when there is tensile load on the wrist strap 20 in one Direction with one running in the longitudinal direction of the stick Force component, the direction of which from the tip of the stick to Stick handle points out, ie according to FIGS. 1 and 2 or 11 above, yields, so that the release means 70 or 170 held connecting element 24, 30 or 124, 130 can be brought into its locked position.

In the first exemplary embodiment according to FIGS. 1 to 10 is the compliant trigger 70 through a lid 72 formed, the one side facing the handle head face 74 of the recess 18 forms. Here, the cover 72 is made from a plate 76 which is pivotable about an axis 78 is stored. When pivoting the plate 76 in In a direction of arrow 83, the recess 18 is to a certain extent opened at the top so that the first connecting element 24 no longer held in the locked position (Figure 2) and without depressing the actuator 44 from Stick handle 10 is removable. Part 80 of plate 76 rests on a resilient element 82 which at Swiveling the plate 76 in the direction of arrow 83 compressed becomes. In a simple variant shown in Figure 2 is the resilient element 82 made of a cushion elastic material formed.

In a variant shown in Figure 7 that is spring-elastic element 82 by a coil spring 84 formed, the resilient force is adjustable, by inserting the spring 84 into the plate 76 screwed grub screw 86 is pre-compressible.

When pulling on the wrist strap 20 in one direction with one running in the longitudinal direction of the stick Force component whose direction from the tip of the stick to Stick handle points upwards, ie according to FIGS. 1 and 2 is directed, the plate 76 in the direction of arrow 83 against the resilient force of the resilient Element 82 pivoted. If the traction on the Wrist strap 20 is large enough, the plate 76 becomes so far pivots that the first connecting element 24 so far is raised that the locking lug 26 is no longer the second Connecting element 30 engages behind. The wrist strap 20 with the first connecting element 24 then comes from the stick handle 10 free.

This trigger mechanism is supported by that with tensile load on the wrist strap not upwards only the release means 70, i.e. the plate 76, upwards can yield, but also a slight rotation of the first connecting element 24 can occur, so that thereby the second connecting element 30 slightly after is pressed down, which still supports the unlatching is so that the plate 76 are pivoted only a little got to.

In a variant that is not shown, this is spring-elastic element 82, the restoring force is adjustable by a cushion wedge made of elastic Material formed between the part 80, the plate 76 and the base body 12 along a bevel of the Base body is slidably mounted. The upholstery wedge can be moved over a thread, for example, whereby the compression properties and thus the Restoring force and thus the release force is infinitely variable is adjustable.

In a further variant of the Invention can trigger 70 by Stick handle material must be formed, which is then in the area of Handle head end face 48 must be correspondingly flexible, to upward in the case of tensile loads on the wrist strap 20 to give way, so that the first connecting element 24 unlocked. In another alternative it would be conceivable that the cover 72 by, for example, belt or Velcro is held under appropriate load to open. It would also be possible to cover 72 by a to establish a positive connection.

It is understood that the trigger means 170 in the second Embodiment according to Figures 11 to 13 accordingly the aforementioned trigger means 70 can be formed.

In a further embodiment of the invention, the Stick grips a locking device 88 through which the release means 70 or 170 can be locked. The Locking device 88 includes one Locking pin 90, which in one in the stick handle bored hole 92 and in a with this hole 92nd aligned bore 94 of the release means 70 can be inserted (Figure 3).

In one shown in Figures 8 and 9 Embodiment of the locking device 88 is the Locking pin 90 via a slide 96 between one Release position and one shown in the figures Lockable position slidable. The slider is from the handle head face 48 accessible and can therefore at seized stick handle 10 slightly actuated with the thumb become. In an alternative embodiment it would take place a slide a rotating mechanism for the Locking device conceivable.

So that the stick handle 120 according to the invention with a wrist strap 20 is convenient and easy to use, is the wrist strap formed according to Figure 10. The wrist strap 20 includes a loop part 100 which tightly encloses the wrist, which can be changed circumferentially using Velcro fasteners. The loop part 100 is widened on the inside of the hand, from which extends a connector 102, which on his free end with the first connecting element 24 or 124 connected is. Next is the first connecting element 24 or 124 connected to a tension element 104, which over the Back of the hand with the grasping the wrist Loop part 100 preferably via Velcro fasteners is connectable. The tension element 104 preferably consists of an elastic material, such as an elastic band or similar. With the wrist strap 20 in place extends the first connecting element 24 or 124 finger-like away from the palm so that when gripping of the stick handle 10, the first connecting element 24 or 124 without further manipulations in the recess 18 or 118 is insertable and there due to the spring-loaded second connecting element 30 or 130 automatically locked. In one embodiment, the wrist strap 20 be incorporated into a glove 106. The user of the The stick handle according to the invention then only needs the gloves tighten and grip the stick handle 10. The glove 106 locked with its first connecting element 24 or 124 then automatically with the stick handle 10. This is one Combination of optimal functionality and simultaneous Security guaranteed.

The stick handle 210 shown in FIGS. 14 to 17 according to a third embodiment also has a base body 212 from, for example, one Injection molded part made of plastic. The base body 212 is also with a covering 214 made of easy-to-grip material Mistake.

While the stick handles 10 and 110 of the first and second Embodiment, the actuator 44 and 144 in is arranged and designed such that a Actuation button 46 or 146 with respect to the stick handle or of the cane 16 arranged axially in the middle and one Opening 47 and 147 in the lid 72 of the release means 70 or 170 penetrates and on the handle head face 48 or 148 protrudes slightly, is the stick handle 210 of the third embodiment, the actuator 244th formed in this way and with respect to the cover 272 of the Trigger means 270 arranged such that it with the provided two openings 247, 247 ' Handle head end face 248 on both sides of the Trigger means 270 is actuated.

For this purpose, the actuator 244 has a U-shaped Base 243, on the two parallel upstanding Each have an actuation button 249 or 251 is integrally formed and the basic or Connecting leg 245, the second connecting element 230 forms. The base leg 245 is in accordance with FIG. 17B in arranged in a lower rear area. Between two upright legs of the U-shaped base 243 the recess 218 for the second connecting element 224 educated. As can be seen in FIG. 14, this has first connecting element 224 a latch 226 and that second connecting element 230 a corresponding undercut locking edge 228. It is also here it can be seen that the recess 218 is not only of the two upright legs of the U-shaped base 243 but also from the base body 212 and the cover 272 of the Trigger means 270 is limited.

The wrist strap is like the first embodiment 220 held in the first connecting element 224. Further is as in the first embodiment, the cover 272 of the Trigger means 270 pivotally mounted about an axis 278, axis 278 near the inner end of the recess 218 is arranged offset in height. Different from the first The embodiment is the rear 280 of the cover 272 provided with an undercut nose 281 that adjusts supports an upstanding part 285 of the base body 212. The nose 281 is designed to be resilient, so that the tensile load on the cover 272 about its axis 278 swiveling at the front according to arrow 283, wherein the nose 281 yields resiliently; to The resilient nose 281 brings about relief, in return of the lid 272 into that shown in FIG Starting position.

The second connecting element 230 or the one identical to it Base leg 245 of the U-shaped base 243 of the Actuator 244 is on the bottom 238 with a Blind hole recess for receiving one end of one axial coil spring 236 provided, the other ends in a pot-like recess protruding into the 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 Embodiment. The two operating buttons 249 and 251 on the U-shaped base 243 are along the inside Boundary surfaces of the cover 272 of the release means 270 and on the outside along the boundary of the rest Cover of the handle head face 248 out. Since the movement buttons 249 and 251 are connected to each other to solve the first Connection element 224 from the stick handle 210 optionally one or the other button is pressed.

According to the sub-figures 17 A and B, the actuation buttons 249 and 251 along their top or operating surface provided a soft layer 253. It goes without saying that this operating area instead also as a hard area can be trained.
