This is a National Stage of International Application No. PCT/EP2015/070239 filed Sep. 4, 2015, claiming priority based on Swiss Patent Application No. 01358/14 filed Sep. 9, 2014, the contents of all of which are incorporated herein by reference in their entirety.
The present invention relates to a hand-retaining device having a coupling element and to a pole handle having a hook-like device for the self-locking fastening of such a hand-retaining device, in particular for a ski pole, a Nordic walking pole, a cross-country pole or a hiking pole.
The prior art, for example DE 299 06 612 U1, discloses either pole handles which are engaged around by the user in a direction transversely to the pole longitudinal axis, or pole handles with a pommel, such as, for example, from DE 10 2006 008 066 A1, which are only suitable to be engaged around from above.
EP 2 168 641 describes an ergonomic pole handle which is suitable to be engaged around in both ways. Said pole handle makes it possible for the user to use it in a manageable and ergonomic manner not only in the engaged-around hand position known of ski poles from a direction substantially transverse to the pole longitudinal axis, but additionally also for support or pushing away by means of the effect of a force from above, which is useful above all, for example, in the case of sloping ground. The pole handle described there comprises a device for the adjustable fastening of a hand strap which is conventional per se. To this end, on the rear pole handle region, the handle head comprises a recess for receiving a hand-retaining device or a clamping element connected to a hand-retaining device. In this case, the device comprises an eccentric element which is rotatable and/or pivotable about an axis. Consequently, the fastening means that is guided in the fastening region between the top surface of the eccentric element and a stationary abutment, or a hand strap or a clamping element fastened thereon, is clamped between the eccentric element and the abutment as a result of rotating or pivoting the eccentric element in the locking rotational direction, the eccentric element being rotatable or pivotable by means of a lever or hinged handle for clamping the hand-retaining device. The length of the hand strap is held here so as to be adjustable, the hand strap, however, is fixedly fastened on the pole handle.
The invention comes into play here. The object accordingly underlying the invention is to provide a hand-retaining device for a pole handle which is improved compared to the prior art. In particular, it involves improving a hand-retaining device for coupling to a pole handle for walking poles, trekking poles, alpine poles, cross-country poles and Nordic walking poles, in particular also for pole handles with a domed handle head which is suitable to be engaged around from above. It is a further object to provide a pole handle which, among other things, is able to be used but does not have to be used, with such a hand-retaining device.
The object is achieved, among other things, by a hand-retaining device that serves for fastening on a pole handle, in particular preferred for a ski pole, a Nordic walking pole, a cross-country pole or a hiking pole, such as, for example, described in EP 2 168 641. The hand-retaining device according to the invention is particularly suitable for fastening on a pole handle as described further below, but is, however, an invention in its own right independent of the pole handle described below and can consequently also be used for fastening on differently developed pole handles. WO 2006/066423 and WO 2006/066424 disclose a pole handle or a hand-retaining device suitable for coupling to the pole handle having a self-locking mechanism. First of all, it does not appear possible to utilize such a coupling mechanism for a pole handle which can be engaged around both from above and from the side, such as, for example, described in EP 2 168 641 as the short distance defined by the coupling element between the retaining mandrel and the hand-retaining device prevents the user from engaging around the pommel from above. The hand-retaining device proposed here or rather the pole handle proposed here allow this in a surprisingly practical and efficient manner, however, with the corresponding adaptations.
The hand-retaining device includes an insertion opening for the hand, a first exit opening for the back of the hand and a second exit opening for the thumb, and also comprises a first strip which is guided between the thumb and the other fingers, on which is provided a coupling element which can be fastened in a self-locking manner in a releasable mechanism in and/or on the pole handle. The core of the invention is that the first strip is realized, at least in regions, in an elastic manner. The elasticity of the first strip, on which the coupling element is fastened, enables a user to engage around the handle head of the pole from above even with the hand-retaining device fastened on the pole handle, i.e. to change from a lateral engaging round position of the handle body into an engaging-around position of the handle head from above and back depending on what the terrain or the walking movement requires. The first strip is preferably elastic in a region of the hand-retaining device on the side of the exterior surface of the hand, i.e. in a region which extends from the coupling element on the side of the top surface of the hand. In contrast, it is preferred when the region of the first strip which extends proceeding from the coupling element to the region of the hand-retaining device on the side of the interior surface of the hand is realized in a non-elastic manner, for example in the form of single-layer or multi-layer webbing which forms said non-elastic region of the first strip or is sewn onto the first strip in the region on the side of the interior surface of the hand. When the hand is pulled, the strain on the hand strap, especially in the region of the hand strap on the side of the interior surface of the hand, is downward and when the hand moves it is upward especially in the region on the side of the exterior surface of the hand. It is consequently preferred that when the hand is moved downward, the length of the first strip is not increased or is hardly increased, whilst when the hand is moved upward (such as, for example, when engaging around the handle head from above) the length of the first strip is greatly increased such that the handle head is able to be engaged around comfortably from above.
When a force of 10N is applied, a strip of a length of 5 cm is to be designated as elastic when at said force it experiences a change in length of at least 3 mm, preferably at least 5 mm, 10 mm or even 15 mm or 20 mm. In contrast to this, “non-elastic” in the context of said invention means that when the abovementioned force of 10 N is applied to a strip of the same length, elongation of less than 3 mm, preferably of less than 2 mm and in particular preferably of less than 1 or 0.5 mm is effected.
According to a preferred embodiment, the hand-retaining device, between the thumb and the other fingers or between the first exit opening for the back of the hand and the second exit opening for the thumb, comprises a second strip which connects a region of the hand-retaining device on the side of the exterior surface of the hand and a region of the hand-retaining device on the side of the interior surface of the hand preferably in one piece. In this case, the first strip overlaps the second strip thereby forming a space. Said gap or separation is necessary so that when the handle head is engaged around from above, the hand strap remains in its normal fit on the hand, whilst, independently of this, the length of the first strip can be stretched as a result of its elasticity and consequently the distance between the coupling element and the hand can be increased. Both strips are loosely placed in the region below the fastening element such that the head of the handle is able to be engaged around. In the subsequent extension of the second strip, it is fastened on the hand-retaining device on the side of the inside surface of the hand in order to be able to absorb tensile forces in the intended direction of stress.
According to a further preferred embodiment, the second strip is multi-layered in the region on the side of the exterior surface of the hand, i.e. realized from at least two preferably non-elastic material layers, and the first elastic strip extends in the region on the side of the exterior surface of the hand between two such material layers of the second strip. The first elastic strip is consequently guided to a certain extent through a tunnel or channel which is formed from the second strip preferably in the region on the side of the exterior surface of the hand. In this case, it can be advantageous when the first elastic strip in the non-extended state does not project out of the tunnel or only projects out a little, and only projects out of the tunnel when the hand of the user engages around the pole handle from above, i.e. when the first elastic strip is acted upon or stretched.
The hand-retaining device, in this case, can be realized as a hand strap or in the form of a glove. In the event of a glove, the coupling element is arranged on a first strip which overlaps the strip or the glove portion, run between the thumb and the index finger. In this case, the strip which runs between the thumb and the index finger and forms part of the glove is to be understood as the second strip.
The first strip is preferably a strip which is fastened on the hand-retaining device and is formed at least in a first region from an elastic or flexible, preferably rubber elastic material. For example, the first elastic region of the elastic strip can be formed from an elastic band or rubber band or a non-woven textile material with elastic and non-elastic regions and/or constituents. The first elastic region is preferably arranged in the region on the side of the exterior surface of the hand. It is also conceivable for the entire first strip to be realized from an elastic band which, however, in the case of a non-elastic region, for example in the region of the hand strap on the side of the interior surface of the hand, is sewn to non-elastic webbing in said non-elastic region.
In a particularly advantageous embodiment, the first strip connects the region of the hand-retaining device on the side of the exterior surface of the hand to the region of the hand-retaining device on the side of the interior surface of the hand, or provides a further connection between said two regions in addition to the second strip. The first strip is fastened on the hand-retaining device preferably on its first end on the side of the exterior surface of the hand and on its second end on the side of the interior surface of the hand, preferably as a result of sewing.
In this case, it is particularly preferred when the hand-retaining device is realized in part in multiple layers in a region on the side of the exterior surface of the hand. In such a case, the first strip is fastened, preferably sewn, on the hand-retaining device preferably on its first end on the side of the exterior surface of the hand, which faces the insertion opening for the hand on the top surface of the hand or exterior surface of the hand, between a first material layer and a second material layer. The seam, in this case, can project through all the material layers of the hand-retaining device. In this case, it is advantageous when the region of the hand-retaining device on the side of the exterior surface of the hand comprises a slot or an insertion opening, through which the first strip, or the elastic region of the first strip can enter and be guided up to its fastening as it were in a “tunnel” between two material layers. The portion of the elastic region of the first strip placed outside the tunnel, measured from the coupling element up to the entry of the first strip into the slot or the insertion opening, is preferably smaller than the tunneled portion which runs under the top material layer of the region of the hand-retaining device on the side of the exterior surface of the hand.
It is particularly advantageous when the first strip, or the end thereof on the side of the exterior surface of the hand, is fastened close to the insertion opening for the hand on the region of the hand-retaining device on the side of the exterior surface of the hand. As a result, the length of the elastic region of the first strip can be maximized and consequently a maximum engaging-around position of the handle head from above is made possible without the elastic restoring force of the elastic strip being felt to be uncomfortable, or the restoring force pulling the user hand back into the lateral engaging-around position. The distance between the fastening or the seam and the edge of the hand-retaining device adjoining the insertion opening for the hand, in this case, is a maximum of between 0.5 and 5 cm, preferably a maximum of between 0.5 and 3 cm. In particular, said fastening is at a distance of between 1.5 and 2.5 cm from said insertion opening for the hand. The distance between the coupling element and the fastening of the first strip in the region on the side of the exterior surface of the hand is preferably greater than that between the coupling element and the fastening of the first strip in the region of the hand-retaining device on the side of the interior surface of the hand.
The first strip in a region between its fastening in the region of the hand-retaining device on the side of the exterior surface of the hand on its first end on the side of the exterior surface of the hand and its fastening in the region of the hand-retaining device on the side of the interior surface of the hand on its second end on the side of the interior surface of the hand, is preferably not fastened on the hand-retaining device, preferably at least in a region of the coupling element or in the vicinity thereof. The first strip consequently sticks out from the main body of the hand-retaining device in a region in which it overlaps the second strip, which connects the region on the side of the interior surface of the hand in one piece to the region of the hand-retaining device on the side of the exterior surface of the hand, thereby forming a space. In the embodiment mentioned further above, where the second strip is realized in multiple layers in the region on the side of the exterior surface of the hand, and where the first elastic strip extends in the region on the side of the exterior surface of the hand between two such material layers of the second strip, said space can be limited to a minimum, i.e. the first strip and the second strip touch one another in said overlap region possibly in regions, but are at least not connected together in said overlap region, or are realized as two separate elements in said overlap region, or are displaceable relative to one another.
The coupling element can be realized, for example, as a toothed rigid element, as a hook-like device or a preferably flexible strap-shaped/ring-shaped or eye-shaped device, wherein the coupling element is realized in a particularly preferred manner as a flexible strap or eye and is essentially produced from a low-stretch, where applicable plaited material, or from a braided or coated wire-like material. The strap or eye preferably consists of a cable or stirrup or a flexible plastics material cord with inherent rigidity. In the event of the strap or eye, the hand-retaining device is particularly suitable for fastening on a pole handle as it comprises a hook-like device on which the hand strap can be coupled.
The hand-retaining device preferably comprises a variably securable first fastening device in the region between the insertion opening for the hand and the first exit opening for the back of the hand, for example by means of two complementary Velcro regions.
It is additionally also an object of the invention to provide an improved pole handle with a hook-like device for the fastening of a hand-retaining device. Said object is achieved in particular by a pole handle suitable for a pole, in particular in a preferred manner for a ski pole, a Nordic walking pole, a cross-country pole or a hiking pole, and comprises a handle body and a handle head with a hook-like device for the fastening of a hand-retaining device, particularly for the fastening of a hand-retaining device, in particular in the form of a hand strap or a glove. The pole handle according to the invention is an invention in its own right independent of the above-described hand-retaining device. The pole handle according to the invention can be used in combination with the hand strap according to the invention, however other hand-retaining devices with a strap-shaped or eye-shaped device can also be coupled to said pole handle. The handle head is preferably integrally molded onto the top handle body region, but can also be integrally molded onto a tube forming the central recess for the pole tube or fitted onto the top handle body region or the tube, or inserted into the tube. The hook-like device, in this case, is fastened on a separate locking module or forms part thereof. The locking module is insertable into a recess which is accessible from one hand side and/or from above, in particular a recess of the handle head which is accessible from above in the axial direction, and is fastenable in and/or on the handle head. Rotatable or displaceable latching means are arranged in and/or on the locking module in such a manner that a coupling element which is realized as a strap-shaped, ring-shaped or eye-shaped device, is essentially pushed from above into the hook-like device and is provided on the hand-retaining device, is fixed in a self-locking manner in or on the hook-like device and on the locking module.
The locking module is preferably fastened on the handle head by means of at least one first cross pin which is arranged transversely with respect to the longitudinal axis of the pole handle. According to a preferred embodiment, the locking module is additionally fastened on the handle head by means of a second cross pin. If the handle head comprises a cover, at least one of the cross pins preferably serves at the same time for fastening a cover on the handle head, as described below.
According to a next preferred embodiment, the handle head comprises a cover which is arranged on its top surface and is realized in a convex manner according to a particularly preferred embodiment and, for reinforcement, can comprise possible struts and/or shoulders and/or further reinforcing and/or guiding structures. The cover is preferably realized so as to be removable. To this end, the cover can comprise for example, a latching lug which projects into the interior of the head region and is fixable there in a self-locking manner in a structure provided for this purpose. As an alternative to this, the handle head can also comprise a latching lug which can hook or latch into an undercut of the cover when the cover is mounted. The cover, on its rear end facing a direction which is opposite to the running direction, preferably comprises two legs which, in the rest position, extend substantially parallel to the longitudinal axis of the pole handle or to a pole longitudinal axis. Said legs can comprise a recess each, through which a second cross pin or axial pin can be guided transversely with respect to the pole longitudinal axis and to the running direction, preferably parallel to a transverse axis of the handle head. The two recesses of the legs, in this case, are preferably in alignment with two recesses in the handle head. The cover is able to be fastened on the head region and, at the same time, the locking module can also be fastened on the handle head for the fastening of a hand strap by means of the second, substantially horizontally arranged cross pin. In this case, the second cross pin preferably penetrates the handle head transversely relative to the pole longitudinal axis and transversely relative to the running direction, as well as the two legs of the cover. The locking module preferably comprises a latching block which is mounted so as to be displaceable and/or rotatable, on or in which latching means are arranged.
In the case of a particularly preferred embodiment, the locking module additionally comprises an actuating element which is fastened on the latching block and can be tilted from the outside against spring force thereby releasing the self-locking.
The actuating element or the release button thereof is developed at least partially so as to form a contour with its top surface preferably on a top surface of the handle head and/or on a hand side directed to the hand-retaining device. In a rest position, the top surface of the actuating element on the top surface of the handle head is integrated at least in part or in particular almost completely in an outside contour of the handle head, and this also remains so during an actuating movement of the actuating element or of the release button. The outside contour of the handle head, in this case, extends in a substantially semicircular or arcuate manner from a tip of the handle head up to a hand-side boundary between the handle head and the handle body.
It is particularly advantageous when the locking module has an axial spiral spring which is arranged in a cavity of the handle body, is pretensioned downward for emergency release and the tension of which is able to be adjusted preferably by means of an adjusting nut.
The latching means are preferably realized in such a manner that in the case of stress that exceeds a normal usage force in the direction of the opening of the hook-shaped device, an emergency release of the strap-shaped, ring-shaped or eye-shaped device is effected.
The latching means are preferably realized in the form of a retaining lug, which in a preferred manner has a beveled flank in the insertion direction upward, and which, in a position tensioned against the hook-like device, defines downward a latching region for the strap-shaped, ring-shaped or eye-shaped device which is restricted against a force, which in a preferred manner is adjustable. According to a particularly preferred embodiment, the retaining lug is preferably connected in one piece to a spring-loaded latching pin, or forms part thereof.
The retaining lug, in this case, is preferably mounted so as to be displaceable, wherein displacement, thereby releasing the restricted latching region against a defined and in a preferred manner adjustable force, is made possible upward, and wherein in a preferred manner the force is ensured by means of a spring or a resilient element. The retaining lug is preferably tensioned with a spiral spring or, as an alternative to this, with an elastomer spring or torsion spring to a displacement position closing the latching region, wherein said tensioning is preferably adjustable such that a safety release is only effected at a force of more than 50-250 N. Said design consequently includes the advantage of an adjustable emergency release for the entire locking module. The release force can be adjusted in a very simple manner by, for example, the locking module being removed from the handle head, and the adjusting nut being adjusted corresponding to the requirements using a corresponding tool. As a result of using a spiral spring, said safety release is also ensured even under the most varied temperature conditions, and, in addition, the spiral spring is well concealed in such a manner in the interior of the pole handle that contamination, icing up or the like can be excluded.
According to a further preferred embodiment, the locking module comprises a fixing element on which the hook-like device is arranged, as well as a latching block on which the latching means are arranged and which is mounted in the handle body downward in the direction of the longitudinal axis of the pole handle by means of an anchoring element. Said locking module preferably additionally comprises a rotatable and/or tiltable actuating element which is realized for releasing the self-locking, wherein the latching block and the actuating element are engaged around by the fixing element and/or are received at least in part in the fixing element.
A particularly advantageous embodiment of the present invention includes a pole handle having a hand-retaining device, or a pole, in particular a ski pole, a Nordic walking pole, a cross-country pole or a hiking pole, having a pole handle according to, and a hand-retaining device is fastened or is fastenable on the pole handle.
A substantial advantage of said modular design is the simplified mounting of the locking module which is produced as an entire unit. As a result of the modular design of the locking module, the locking module is producible as an individual assembly and can be inserted into a handle head or handle body. In addition, as a result of the locking module being received in the recess of the handle head, the retaining mandrel or the hook-shaped device is embedded in an optimum manner in the outside contour of the pole handle, and is not felt to be obtrusive.
Further exemplary embodiments are described in the dependent claims.
Preferred embodiments of the invention are described below by way of the drawings which serve purely for explanation and are not to be seen as restricting, in which:
The pole handle 1 shown comprises a longitudinal axis 56, a handle body 3 with a front pole handle region 3a pointing in a running direction or movement direction B and a rear pole handle region 3b which is aligned in the opposite direction to the running direction. The pole handle 1 or the handle body 3 thereof has, from below, a central recess or a cavity 5, which is arranged along the or substantially parallel to the pole handle longitudinal axis 56 (not shown in the figure) and into which the pole, which is formed, for example, from an aluminum or carbon or glass-fiber tube, can be inserted and fastened therein. The pole handle shown in
The pole handle 1 additionally comprises an arched handle head 2 which connects to the top of the handle body 3. The handle head 2 comprises a handle nose with a tip 65 or is formed in part by a handle nose which merges substantially in a shoulderless manner into the top region of the handle body in the front pole handle region 3a. The handle lug in the front pole handle region 3a is realized in a protrusion projecting beyond the handle body region in the running direction B. The handle head 2 has a recess 4, which is open upward and toward the user hand or toward the hand side H and in which a locking module 6 is arranged. The locking module 6 is shown in detail in
It can be seen in
In the preferred exemplary embodiment shown, the latching block 20, the anchoring element 57 and the actuating element 9 are all held by the fixing element 15. The fixing element 15 is realized in regions in a shell-shaped manner. It comprises a first leg 7 and a second leg 8 which form a shell-shaped region, as well as a web 13 which connects the legs 7, 8 of the fixing element 15 to a hook-shaped device 14 that is realized as a retaining mandrel. In this case, the two legs 7, 8 enclose the two side walls 20a, 20b of the latching block 20. The retaining mandrel 14 in said exemplary embodiment is connected in one piece to the shell-shaped region of the fixing element 15. The bottom surface of the fixing element 15 forms a bottom 64 which serves for supporting the fixing element 15 or the entire locking module 6 on the support surface 63 in the transition region between the handle head 2 and the handle body 3.
A retaining pin 31, which projects through the bore 58 into the cavity of the handle body 3, is attached on the locking module 6 over an axis 56. The retaining pin 31 has an eye 32 on the top side for the rotatable fastening on the locking module 6 with the axis 33. For fastening the anchoring element 57 on the latching block 20, the anchoring element 57 with its eye 32 is introduced from below into a recess 60 of the latching block 20 which is flanked by two small legs in the bottom region of the latching block 20. Said legs comprise one through-bore 61b each which is suitable to receive a pin 34 along an axis 33, the pin 34, for the purposes of fastening the anchoring element 57, penetrating the respective bore 61 of the legs of the latching block 20, and in between the eye 32 of the anchoring element 57.
On its bottom end, the retaining pin 31 is provided with a thread. The retaining pin 31, or rather the entire locking module 6 fastened thereon by means of the latching block 20, is tensioned downward with the aid of a stop element 29, which abuts against the top cover of the cavity or against the bottom surface of the support surface 63, with a spiral spring 28 by means of an adjusting nut 30, which is screwed onto the thread of the retaining pin 31 from below. At one end the spiral spring 28 rests from below on the top stop element 29 on a correspondingly provided shoulder, and at the other end from above on the bottom stop element 40.
A latching pin 10, which serves for the automatic latching of the coupling element 79, for example in the form of a strap-shaped/ring-shaped or eye-shaped device, is arranged in the locking module 6, or in the latching block 20 forming part of the locking module 6. The latching pin 10 is arranged substantially horizontally with respect to the longitudinal axis 56. It is mounted in the locking module 6 in a recess or bore 54 specifically provided for this purpose so as to be displaceable along an axis 88, the latching pin 10 being tensioned against the retaining mandrel 14 by means of a spiral spring 35. The latching pin 10 has a retaining lug 11 which, in a preferred manner, is beveled from above and is realized substantially horizontally at the bottom such that, for example, a strap-shaped/ring-shaped or eye-shaped device 79 inserted from above, displaces the latching pin 10 rearward against the spring tension of the spiral spring 35 and the strap-shaped/ring-shaped or eye-shaped device 79 is captive under the latching pin 10 in the latching region 59. The latching pin 10 comprises a (through-)bore 62 which extends horizontally with respect to the pin axis 88 and through which a cross pin/guide pin 39 is inserted in order to guide the latching pin 10 inside an elongate hole 41 in the interior of the latching block 20.
The locking module 6 has an actuating element 9 with a release button 37 on the top surface 68. In the present exemplary embodiment, said release button 37 is connected in one piece to the actuating element 9 or to the wings 9a, 9b thereof. The latching block 20, or the side walls 20a, 20b thereof, are surrounded from above and behind, i.e. when viewed from the retaining mandrel 14, by the two wings 9a, 9b of the actuating element 9. The portion of the latching block 20 which is directed rearward (toward the retaining mandrel 14 or toward the hand) and comprises the recess 54 for the latching pin 10 is inserted, in this case, from below into a recess 27 of the actuating element 9. The recess 27 is realized as a result of the realization of the wings 9a, 9b of the actuating element 9 in the manner of an inverted U-shape. The latching block 20 additionally comprises a top shoulder 21, the width of which is greater than the length of the through-bore 26, measured in a direction horizontally to the longitudinal axis 56. Said shoulder 21 rests on the top of a back 89 of the actuating element 9. The great advantage of said design is that the projections or wings 9a, 9b of the actuating element 9 are positioned in an ideal manner for the actuation of the desired release, however an unwanted release is nevertheless able to be avoided completely.
If the strap-shaped/ring-shaped or eye-shaped device 79 pushed over the retaining mandrel 14 is to be released from the latching region 59 under normal conditions, a release button 37 is provided for this purpose on the top surface 68 in the locking module 6 or on the actuating element 9. A rotational axis 38 is arranged horizontally and transversely with respect to the direction of the latching pin 10 in the locking module 6. The actuating element 9 forming the release button 37 is mounted inside the locking module 6 so as to be tiltable about said rotational axis 38 (anti-clockwise in
With the actuating element 9 in a rest position, the guide pin 39 rests at the bottommost end of the respective elongate hole 51a, 51b, and during the rotational movement D of the actuating element 9 in the running direction B is pushed upward at an angle. The respective elongate hole 51a, 51b comprises to this end a direction of movement which is arranged angled downward in relation to that of the elongate hole 41 in the latching block 20. Thus, the rotational movement D of the actuating element 9 is converted into a displacement movement of the latching pin 10 along the axis 88 substantially in the running direction B: If the release button 37, which in the present exemplary embodiment is realized in one piece with the lateral projections or wings 9a, 9b, is pressed downward, for example by the thumb of the hand gripping the pole, the actuating element 9 tilts slightly downward as one unit and as a result, when rotating about the rotational axis 38 (in arrow direction D in
The latching block 20 is consequently held in the actuating element 9 by two pins: on the one side by the axial pin 19 which is arranged along the rotational axis 24 of the locking module 6 and also at the same time connects the latching block 20 and the actuating element 9 to the respective leg 7, 8 of the fixing element 15, and secondly by the guide pin 39 which, when viewed from inside to outside, connects the latching pin 10 to the latching block 20 and then to the actuating element 9.
On a top region, the latching block 20 comprises a through-bore 26 which is arranged horizontally with respect to the longitudinal axis 56 of the pole handle 2 and is suitable to receive an axial pin 19 along a rotational axis 24. The axial pin 19, in this case,—when viewed from inside to outside-first of all penetrates said bore 26 in the latching block 20, then two bores 43a, 43b in the respective wings 9a, 9b of the actuating element 9, as well as the respective bore 42a, 42b of the respective above-described legs 7, 8 of the fixing element or of the fixing shell 15. As a result, the actuating element 9 rotates about the rotational axis 38 on the latching block 20. During the rotational movement of the actuating element 9, only the actuating element 9 and the latching pin 10, and the spiral spring 35 thereof, move in the locking module 6, not, however, the latching block 20 itself or the fixing element 15. When the locking module 6 is inserted in the handle head 2, the through-bore 26 in the latching block 20, the bores 43b in the fastening element 9, the bores 42a, 42b in the fixing element 15 extend coaxially to one another along the axis 24, along with the axial pin 19 which is inserted therein and connects the fastening element 9, the latching block 20 and the fixing element 15 to the handle head 2.
By inserting the locking module 6 into the recess 4 of the handle head 2, the retaining mandrel 14 is embedded optimally in the outside contour of the pole handle 1. Nevertheless, there is still an ideal insertion opening from above for an eye/strap 79, as shown in
In addition, the locking module 6 is fastened on the handle head 2 along an axis 44 transversely with respect to the longitudinal axis 56 of the pole handle 1 by means of a further cross/fastening pin 45. Said pin engages from outside through a bore 49a or 49b on the outside of the handle head into the recess 4, and then through the bore 47a or 47b in the legs 7 or 8 of the fixing element 15. In the present exemplary embodiment in
The advantage of the arrangement of said further cross pin 45 is that the torsion forces which are brought about by the tilting of the actuating element 9 about the rotational axis 38 and at all events—in particular in the event of a fall—also by the rotating of the entire locking module 6 about the rotational axis 24, are better absorbed.
The pole handle 1 according to the exemplary embodiment shown in
In the exemplary embodiment shown, a latching lug (not shown), which, in the fitted state, projects from the front handle head edge into the hollow region of the cover 6 and there latches into a recess or an undercut on the inside surface of the cover 6, is arranged in the front tapering region of the handle head 2. In the exemplary embodiment shown, the inside surface of the cover 6 comprises several struts (not shown). A cutout 25 for the release button 37 of the actuating element 9 is arranged in the rear portion of the cover 6 which, in the mounted state, faces the rear pole handle region 3b, i.e. points in a direction H opposite to the running direction B.
For mounting the locking module 6, which is produced as an entire unit, it can be inserted from above into the recess 4 in the pole handle 1, the anchoring element 57 provided on the locking module 6 being inserted into the through-bore 58 between the recess 4 and the cavity 5 for the pole tube in the handle body 3. On the retaining pin 31, the anchoring element comprises a top stop element 29, as well as a spiral spring 28 which is pushed over the retaining pin 31, and a bottom stop element 40, which is screwed from below onto the thread of the retaining pin 31, and an adjusting nut 30. The downward spring-elastic retaining force, which is exerted onto the locking module 6 by means of the spiral spring 28, can be adjusted by the adjusting nut 30 being screwed upward more or less. Finally, a fastening pin 46 can be pushed in laterally through the bores 50b, 50c in the handle head 2 along an axis 38.
When viewed from outside to inside (from both sides of the handle head), the fastening pin 46 penetrates the bores 50a or 50b in the handle body 2, as well as the bores 48a or 48b of the legs 7 or 8 of the fixing element 15, then the two bores 52b of the wings 9a, 9b of the actuating element 9, and then the bore 53 of the latching block 20.
Between the bores 50a, 50b in the handle head 2 and the bores 48a, 48b in the fixing element 15, the fastening pin 46 additionally penetrates, according to a particularly preferred exemplary embodiment, on each side of the handle head, a bore/recess of a leg of a cover 12 (the legs not being visible in
The fastening pin 46 consequently serves at the same time for fastening the locking module 6 in the handle head 2 and fastening the cover 12.
The adjustable emergency release of the entire locking module 6 produced by said design functions as follows: If an excessive force (for example in the case of a fall) is exerted from below namely onto the retaining lug 11 by a strap-shaped/ring-shaped or eye-shaped device 79, the entire locking module 6 is rotated about the rotational axis 24, (in the representation of
The hand strap 70 according to the exemplary embodiment shown comprises an insertion opening 71 for the hand, a first exit opening 72 for the back of the hand and a second exit opening 73 for the thumb.
The hand strap 70 is fastened on a pole handle 1 of the pole at least indirectly by means of a first strip 74 which is guided between the thumb and the other fingers.
The head region of the pole handle 1 shown in
The actual hand-retaining device 70, which is realized as a hand strap 70 in the present exemplary embodiment in
Said strip then has at least one variable connecting region. The variable region is the region between the opening 72 for the back of the hand and the insertion opening 71 for the hand. In said region, a first Velcro strip 82 is provided for adjusting and fastening the hand strap on the hand. In the present exemplary embodiment, said Velcro strip is a webbing on the outside surface of which two complementary Velcro regions are mounted, a first Velcro region in the end region and a second Velcro region of complementary type in the region in which said first Velcro strip 82 is sewn to the hand strap. The free end of the fastening strip 82 is guided through a feed-through stirrup 84. The loose end of said fastening strip 82 in the non-fastened state typically has a retaining aid 82a which can be realized, for example, by a hemmed turnover of the webbing. Said retaining aid also serves for the purpose of preventing to a large extent the fastening strip 82 from unintentionally sliding through the feed-through stirrup 84. The fastening strip 82 can be placed around said feed-through stirrup 84 for fastening the hand strap on the hand, the first Velcro region coming to rest on the second Velcro region and it thus being possible to adjust in a fixed lasting manner the distance between the regions 85 and 86 (two ends of the hand strap), in dependence on the size of the hand and in dependence on whether the user wears gloves or not.
In the hand-retaining device according to the invention, a coupling device 79, which is realized as a strap-shaped/ring-shaped or eye-shaped device, is fastened on a first strip 74 for fastening the hand-retaining device on a pole handle. Said first strip 74 overlaps a second strip 75 which, as mentioned above, is guided between the thumb and the fingers and, in the present exemplary embodiment, is connected in one piece to the region 76 on the side of the exterior surface of the hand and to the region 77 on the side of the interior surface of the hand of the hand-retaining device 70. Said first strip 74 is realized in part in an elastic manner. In the exemplary embodiment shown in
In order to keep the length of the elastic region 74a of the first strip 74 as long as possible, the fastening 66 of the end of the first strip 74 on the side of the exterior surface of the hand is to be mounted as close as possible to the insertion opening 71 for the hand. As a result, the seam in the event of fastening through sewing is then to be close to the feedthrough stirrup 84. In the present exemplary embodiment, the fastening is arranged at a distance d of approximately between 1.5 and 2.5 cm away from the insertion opening 71 for the hand, measured from the edge of the hand strap 70 at the insertion opening 71 for the hand on the hand side H.
The second strip 75, which connects the region 76 of the hand-retaining device 70 on the side of the exterior surface of the hand to the region 77 on the side of the interior surface of the hand, is realized in a substantially non-elastic manner, or only insofar as the material chosen for the hand-retaining device is elastic per se. At all events, the second strip 75 is realized in a reinforced manner, e.g. by sewing on a webbing strip, preferably on its top surface which is directed toward the first strip.
In the present example, the first strip 74 is only realized in an elastic manner in the region 76 on the side of the exterior surface of the hand, i.e. no further than up to the fastening region 87 where the hand strap 70 is fastened on a pole handle 1, or where the coupling element 79 is arranged. The first strip could, however, also be realized in an elastic manner additionally in the region 77 of the hand-retaining device 70 on the side of the interior surface of the hand.
In the present exemplary embodiment, the hand-retaining device 70 is realized in a reinforced manner by a reinforcing edge 80 at its three openings 71, 72, 73. This increases the wearing comfort and contributes to the dimensional stability of the hand strap such that the hand strap has a certain inherent rigidity even in the non-worn state and does not collapse, which makes inserting the hand easier. In the present exemplary embodiment, the reinforcing edge is consequently a textile or webbing strip which is folded over the edge region of the hand strap at the boundary to the openings and sewn and/or bonded in said regions with the material of the hand strap. As a result, the hand strap abuts as comfortably as possible against the hand. However, the reinforcing edge does not necessarily have to consist of a separate strip material or band material, but can be formed by a seam or a join to a certain extent from the edge region of the material strip forming the hand strap.
