Technical Field
The invention relates to a pole handle, in particular to a pole handle for walking poles, climbing poles, alpine ski poles, cross-country ski poles and Nordic walking poles. The pole grip has a grip body with a hook-shaped device for fastening a hand-holding device, in particular in the form of a bracelet or glove. The invention also relates to a pole having such a pole grip and to a method for mounting such a pole grip.
Background
In such devices, for example, from US5,516,150, a hook is provided on the pole grip and, at the associated glove, an arc-shaped device which is rigid and formed by a hard metal arch is provided in the region between the thumb and the index finger. The bow is introduced with its long, straight side into the narrow slot of the hook and, via the hook-shaped device, the bow and thus the glove is fixed to the pole grip.
In this case, a slight widening of the slot is provided in the lower middle of the hook, which causes the clip, when it is moved into the hook, to first press the two side edges of the hook slightly apart from one another (material deformation) and only when the clip has been pushed into the widening does the side edges return again into the starting position.
Thus, the elastic deformation of the hook device serves to ensure easy fixing of the bow in the hook and to avoid the bow from easily slipping out of the hook.
The following facts are particularly problematic at such devices: repeated deformation of such components, which are usually formed from plastic or metal, is undesirable due to fatigue phenomena.
Furthermore, the following problems arise in particular: the elastic deformation behavior of a material is extremely temperature dependent. The fixing effect obtained by deformation is therefore neither settable nor constant for different temperatures. The release cannot be clearly defined and the release values are generally not reproducible or very difficult to reproduce.
This is unacceptable in particular in the sports field, since large temperature differences inevitably occur on the one hand due to different weather conditions and on the other hand due to the warming up during use.
A pole grip is known from US5,110,154, in which a connection is established between the pole grip and a hand-holding device in that: a hard ring or bow fixed to the hand-holding device can be pushed into a recess in the form of a horizontal slot provided in the surface of the pole grip facing the hand-holding device. The slot is arranged here perpendicularly to the axis of the grip and must be of narrow design for good fastening, with the corresponding difficulty that the hand-holding device or a hard bow fastened thereto is introduced into the slot for fastening to the pole grip. For this purpose, a precise positioning of the bow relative to the slot must be employed, which is practically impractical.
From WO2006/066423 a pole grip is known, in particular for walking poles, climbing poles, alpine ski poles, cross-country ski poles, nordic walking poles, which has a grip body and a hook-shaped device for fastening a hand holding device, in particular in the form of a bracelet or a glove. In this case, a locking mechanism is provided in the region of the hook-shaped device, so that a loop-shaped, loop-shaped or eyelet-shaped device which is pushed into the hook-shaped device from above and is arranged on the hand-held device is secured in the hook-shaped device in a self-locking manner. In order to remove the loop-shaped, ring-shaped or eyelet-shaped device from the hook-shaped device, a button is provided in the crown, by means of which the locking mechanism can be moved or twisted so that it releases the previously closed region and the device can be removed again upwards. Such a self-locking mechanism with a release mechanism simplifies the operation, but is relatively complex and not suitable for all target groups.
A similar pole grip is known from WO2007/090310, but the device for self-locking fastening here comprises at least one recess for receiving a coupling element, particularly preferably in the form of an arch or a ring, which is arranged on the hand-holding device, wherein the device has a clamping element and the recess of the device is exposed in the insertion position of the clamping element, so that a coupling element of the hand-holding device, which is not connected to the pole grip, can be inserted into the recess, and wherein the device can be brought into a locking position, in which the recess is closed and the coupling element snaps into the recess, as a result of the clamping element being tilted.
EP- ｃA-2745888 describes ｃA handle with ｃA bracelet comprising ｃA strap connected to an insert. The body of the shank is oriented along a longitudinal axis. The insert housing is disposed in the upper end of the body such that the insert is inserted into the housing in a direction parallel to the axis. A locking mechanism holds the insert in the housing, wherein unlocking of said mechanism is effected directly by moving the insert in a direction opposite to the introduction direction of the insert. The locking mechanism comprises a locking device movable relative to the body.
Disclosure of Invention
Accordingly, it is an object of the invention to provide a simplified and nevertheless stable and reliable pole grip construction, in which a hand-holding device having a coupling element in the form of a bow or a loop can be fixed to the pole grip in a self-locking manner and, if necessary, can also be easily released again from said fixing.
The object of the invention is achieved by a pole grip having the features according to claim 1.
The invention accordingly relates to a pole grip, in particular for walking poles, climbing poles, alpine ski poles, cross-country ski poles, nordic walking poles, having a grip body and a hook-shaped device for fastening a hand-holding device, in particular in the form of a bracelet or a glove.
In this case, a movable locking mechanism (here, not a device with a rotatable locking mechanism, but a device which can be moved along an axis without any rotation of the locking mechanism, but rather a locking mechanism which can be moved along the axis without any rotation along the axis, wherein the locking mechanism is a component which in turn prevents a looped, looped or eyelet-like device being pushed in) is arranged in the region of the hook-shaped device, so that the looped, looped or eyelet-like device which is pushed into the hook-shaped device substantially from above and is arranged on the hand-held device (for example according to WO 2006/066424) is fixed in the hook-shaped device in a self-locking manner.
In this case, a movably mounted locking mechanism is explicitly provided, rather than a structure which ensures locking by material deformation or twisting, as is the case, for example, in the initially mentioned US5,516,150. As already mentioned, a great disadvantage of such a construction is that the corresponding material deformation is very temperature-dependent and the force for removal is correspondingly too great, in particular at low temperatures, or too small at high temperatures, and fatigue or material ageing and hardening adversely affects the effect.
In the pole grip proposed here, the hook-shaped device on the pole grip is arranged in the upper region on the hand side and comprises a retaining projection or a retaining pin which is spaced apart from the grip body towards the hand side in order to form an upwardly open insertion slit or is arranged as a cutout in the grip body.
The locking mechanism is designed in the form of a blocking projection which, in the tensioned position, limits the region of the device for loop, loop or eyelet with a limited relative force.
The proposed pole grip is then characterized in particular in that it is precisely and, in contrast to the constructions known from WO2006/066423 or WO2007/090310, for example, free of mechanisms by means of which the user can actively move or otherwise release the locking mechanism, so that the loop-shaped, ring-shaped or eyelet-shaped device which has been pushed into the hook-shaped device can be removed from the restricted region without force or against a significantly smaller force in order to detach the hand holding device from the pole grip.
It has surprisingly been found that if the locking mechanism is supported in the pole grip as a movable and non-rotatable or tip-over element, it can be sufficient and always still effective to design a very good but also relatively complex structure per se for many applications, as it is from WO2006/066423 or WO2007/090310, when the release mechanism according to W02006/066423 or W02007/090310 is dispensed with. In particular, the structure as proposed here is surprisingly always sufficient even at prohibitively low or very high temperatures.
In contrast to the constructions known from WO2006/066423 or WO2007/090310, in the construction proposed here, the hand-holding device is released from the state of being fixed on the pole grip by the hand-holding device being pulled in a targeted manner upwards until the locking device releases the loop again as a result of the temporary movement of the locking mechanism. In the constructions as known from WO2006/066423 or WO2007/090310, this functionality, although in some embodiments also designed for safe release, is always combined here with a separate release mechanism, i.e. a push button, a lever or the like, which is arranged on the pole grip and which to some extent moves or swivels the locking mechanism out of the insertion slit, so that the loop can then be removed from the slit essentially without force.
Furthermore, the force for safety release in these constructions according to W02006/066423 or W02007/090310 is also significantly greater than the force set when supported with the locking mechanism proposed here. In particular, within the scope of the invention, the force for extracting the bracelet (substantially parallel to the introduction direction of said ring) is generally set in the range of 60-100N, preferably in the range of 70-90N.
A first preferred embodiment of the invention is characterized in that the locking mechanism is designed as a locking pin which can be moved in the direction of movement against a restoring force, wherein the locking pin is tensioned in the shank against a retaining projection and/or against an internal stop, and a front region of the locking pin projects behind the retaining projection into the insertion slot or cutout and upwardly delimits a restricted region for the loop-shaped, ring-shaped or eyelet-shaped device, and a rear region in the shank is movably mounted in the recess.
The restoring force can be ensured, for example, by a spring, in particular in the form of a helical spring, which is arranged in a recess, wherein, for example, the helical spring at least partially surrounds an end section of the locking pin which is directed toward the pole grip.
The stick handle preferably being along the handThe pole axis extends and the introduction slit or cut-out behind the retaining projection defines an introduction direction running substantially parallel to the pole axis. According to a more particularly preferred embodiment, the direction of movement of the locking pin towards the retaining projection then forms an angle of less than 90 ° with the upwardly oriented pole axis direction
Now, this arrangement just leads to: although on the one hand sufficient fixing of the ring or eyelet is ensured against unintentional release from the pole shaft and said ring or eyelet can also be introduced easily from above, on the other hand it is also possible to remove it sufficiently easily.
In fact, for example, it is structurally particularly simple to provide: as also according to a preferred embodiment, the force for introducing the loop-shaped, ring-shaped or eyelet-shaped device from behind or below the locking pin is smaller than the force required for removing the loop-shaped, ring-shaped or eyelet-shaped device.
This is important and advantageous for the following reasons: it should be easier for the user to fasten the bracelet to the pole grip and, in addition, to be able to apply the force for locking more easily, since this corresponds to the load that the bracelet is normally subjected to on the pole grip. Conversely, the bracelet should not be able to be inadvertently released from the handle, that is to say the extraction force should be greater than the introduction force. Typically, the introduction force for locking the ring behind the retaining protrusion is in the range of 50-70N, preferably in the range of 55-65N, and the force for releasing is in the range of 70-90N, preferably in the range of 75-85N. The force is here considered to be measured parallel to the direction of introduction, i.e. substantially parallel to the pole axis.
Angle of rotation
Alternatively, it is possible to set the force relationship exactly in reverse, that is to say that the force for introducing the ring-shaped, ring-shaped or eyelet-shaped device from behind or below the locking pin is greater than the force required for removing the ring-shaped, ring-shaped or eyelet-shaped device. This is achieved, for example, by the direction of movement of the locking pin towards the retaining projection being at an angle of more than 90 ° to the upwardly oriented pole axis direction
In the rest state, the tip of the locking pin can contact the retaining projection or be spaced from the retaining projection by no more than 1mm, preferably no more than 0.5mm or 0.2 mm. The combination of this slight spacing with the hemispherical rounding and the above-mentioned angles can provide a particularly good construction.
The locking pin is preferably composed of metal or a high-strength plastic, for example glass fiber-reinforced, in particular polyamide or polypropylene. The shank body is preferably made of a thermoplastic material, for example polypropylene, wherein the shank body can also have a coating or lining made of another material, for example a softer (for example elastomer) plastic material or a cork coating, in certain shank regions.
The locking pin is particularly preferably mounted movably as a cylindrical (metal) pin in the shank body in such a way that, in the region of the adjoining insertion slot or cutout, the front region is guided in a cylindrical guide recess which widens towards the interior of the shank body in order to form a step to the recess in question.
The locking pin can have a circumferential collar adjoining the front region on the inside, the outer radius of which is substantially equal to or smaller than the inner radius of the recess mentioned, but is larger than the radius of the guide recess.
The rear region of the locking pin is preferably proximate to the flange towards the interior of the shank body and has a smaller outer radius than the flange, preferably equal to or slightly smaller than the front region of the locking pin.
The helical spring can then surround the rear region and bear against the flange. Instead of a helical spring, it is also possible to have a hollow-cylinder elastomer spring or generally an elastomer spring, which is then arranged, for example, between the closing pin and the inner end of the locking pin. In this case, the rear end of the locking pin can then be configured cylindrically without a heel behind the flange.
The locking pin preferably has a diameter in the range of 1-8mm, preferably in the range of 2-6mm, in particular in the range of 3-5mm, at least in the front region, preferably in the front region and in the rear region.
A further preferred embodiment, which is modular to a certain extent, is characterized in that a separate fastening block with a retaining projection, a locking pin and a guide for the locking pin is immovably fastened in a recess of the shank body, wherein the recess is preferably designed as a recess extending in the walking direction, so that the head region is formed laterally by the shank body. The fixed block is preferably fixed in the shank via at least one or preferably two transverse pins.
The holding block can have a through-hole for the locking pin, which is closed on the rear side of the holding block by a closing pin, preferably made of metal or plastic. The closing bolt can be glued, pressed in, screwed in or snapped in or a combination thereof. The fastening block can have a guide cylinder for the locking pin and at least one through-opening extending transversely to the walking direction (to reduce weight).
A further preferred embodiment is characterized in that the fastening block has two through-holes extending transversely to the pole axis or recesses which are each formed as a blind hole from both sides and are fastened in recesses in the grip body by means of corresponding transverse pins, wherein at least one of the transverse pins, preferably the transverse pin arranged further above with respect to the grip, additionally serves for fastening a covering cap which delimits the grip at least partially upwards, in that: the covering cap preferably has downwardly oriented fixing arms with through-holes for the respective transverse pins.
Such a covering cap having a convex surface forming the upper surface of the crown can be provided with a non-slip and/or soft (plastic) coating (for example as a two-part component) or be composed of a correspondingly non-slip and/or soft material at least in the outwardly exposed region.
The pole grip preferably has: a lower grip region which forms a lower grip region of the pole grip and has a recess for the pole shaft at the lower end; and a head region. The head region preferably has a front widening which transitions substantially smoothly into an upper grip region in the region of the front pole grip.
The widened portion preferably forms a projection in the region of the front pole grip extending in the walking direction beyond the grip region. In this case, the projection is preferably greater than 50% of the average extension of the grip region in the direction of travel. It is also preferred that a sectional plane of the head region, which opens out via a transverse axis of the head region, which is arranged transversely to the pole longitudinal axis and transversely to the walking direction, and the foremost point of the widening, forms an obtuse angle, preferably in the range of 90 to 135 degrees, with the pole longitudinal axis, the transverse axis being arranged where the head region is widest, measured transversely to the walking direction and transversely to the pole longitudinal axis.
The head region preferably has a rounded contour in the sectional plane. The front section thereof facing the walking direction is preferably substantially defined by the arc of a first circle, while the rear section thereof opposite the walking direction is substantially defined by the arc of a second circle. The centre points of the first circle and the second circle are preferably arranged offset from one another in the direction of travel by 0.5-6cm, wherein the radius of curvature of the first circle is smaller than the radius of curvature of the second circle in the region of the rear pole grip.
The invention further relates to a pole, in particular a walking pole, a climbing pole, a alpine ski pole, a cross-country ski pole or a nordic walking pole, having a pole grip as described above, a preferably one-piece or multi-piece pole tube (with an outer and/or inner clamping of the tube section) which can be adjusted as required, and a pole tip. The pole is provided alone or in combination with a hand holding device, in particular in the form of a bracelet or glove, on which a loop-shaped, ring-shaped or eyelet-shaped device is provided (for example according to WO 2006/066424). Preferably, in combination with the pole grip proposed herein, a bracelet is used comprising: an introduction opening for a hand; a first outlet for the back of the hand; and a second outlet for the thumb, wherein the hand-holding device further has a first strap guided between the thumb and the other finger, on which strap a coupling element is arranged, which can be fixed in a self-locking manner in or at the pole grip in a releasable mechanism, wherein the hand loop is characterized in that the first strap is designed to be elastic at least in regions on the outside hand side of the coupling element. Such a bracelet is known, for example, from WO 2016/037940, and its disclosure relating to bracelets is expressly incorporated herein.
Finally, the invention relates to a method for installing a pole grip of the type mentioned above, which is characterized in particular in that a locking pin is pushed into the retaining block, from its rear side into the recess and in particular into the guide recess; pushing a spiral spring; and closing the recess with a closing plug on the rear side; subsequently, the fixing block is inserted into a recess in the grip body of the stick grip; subsequently, as far as present, the covering cap is inserted to substantially close the final surface of the crown and is preferably locked in the tip region; and then the fixing block and the cap are fixed by means of the transverse pins, provided that the transverse pins of the transverse pins used for fixing the fixing block can also be used only for mounting the cap.

Detailed Description
Fig. 1 shows a side view of a pole grip from obliquely above and behind when the bracelet is unlocked, and fig. 2 shows a side view of such a pole grip from obliquely above and in front of it. Fig. 3 and 4 show the handle from above or below. Figure 5 shows a rear view of the pole grip.
The pole grip 1 has a front side 45 and a hand side 44 which are arranged with respect to the walking direction 30.
The pole grip 1 has a
The pole grip 1 has an
If the user for example uses the pole to descend a hill or simply wants to hold the pole in the uppermost area, the widened region 32 of the front side can be comfortably held by the user.
Correspondingly, in this region, there is also a cover element 33 facing upwards, which has a convex outer surface 57 that is of knotted or corrugated design and has a softer or slip-resistant surface coating 33a (for example made of thermoplastic elastomer (TPE) or EVA).
The
The bracelet 41 is designed here as a hand-securable bracelet with three openings (known for example from WO 2016/037940), the bracelet 41 being made of a hard and non-stretchable tear-resistant material (for example woven UHMwPE, for example) Forming a ring 42 (see fig. 6).
By pulling the loop 42 over the retaining protrusion 14, the entire bracelet 41 can be fixed to the pole grip 1 via this loop 42.
The retaining projection 14 or the region of the pole shank 1 surrounding the retaining projection 14 is designed such that the ring 42 itself locks onto the retaining projection 14. This will be explained in more detail below.
The details of the design of the head region 31 of the pole shaft 1 can be seen particularly clearly in fig. 6 and 7. Fig. 6 shows a cross section along a-a in fig. 5, while fig. 7 shows the detail of the section Z shown in fig. 6.
In the region on the hand side, the crown 31 has a fastening block 6 fitted into it. The fixing block has a retaining projection 14 which is arranged to some extent in a recess 16 of the fixing block 6.
Between this recess 16 and the retaining projection 14 there is a semicircular insertion slot 43 into which the ring 42 can be pushed downwards in a self-locking manner. In order to facilitate this insertion, the region of the slot 43 facing the crown is designed as a concave run-in region 17.
If the ring 42 is pulled down with sufficient force by means of the bracelet 41, the locking pin 7 disposed in this slot moves into the interior of the crown. This overcomes the spring force and after the locking pin has been reset, locks the ring 42 in such a way that the ring 42 is then jammed in the quasi-closed region 15 below the tip 9 of the locking pin 7.
The details of the structure of the fixing block 6 can be seen most clearly in fig. 7. The fastening block is shown here with a continuous recess 20 in the transverse direction. However, it is also possible for the fastening block 6 to be closed at least in the central region.
The fixing block 6 has first an upper transverse through hole 18 and a lower transverse through hole 19. The fixing block 6 is pushed into a recess 4 in the
An upper transverse pin 27, which simultaneously serves to fix the covering element 33 on the shank head, passes through the upper transverse through-hole 18 of the fixing block 6 and through an upper through-hole 51 in the shank body, as will be explained below.
The fastening block 6 now has the named retaining projections 14 on the hand side in one piece. The retaining projection is separated from the remaining fastening block 6 by the recess 16, so that an insertion slot 43 is formed between the mentioned concave insertion surface 17 and the retaining projection.
The introduction direction 46 is arranged substantially parallel to the pole axis 29, in particular along the introduction face 17. The main direction of the holding projection 14 can be arranged slightly obliquely outward, i.e. the lead-in slot 43 can be designed slightly V-shaped. As can be seen in particular from fig. 7, the main direction of the holding projection 14 can also be vertical, and the structuring of the holding projection tapers upwards, so that a V-shaped lead-in slot 43 is formed as shown in the drawing in the sectional view.
On the inner surface of the insertion region 17 facing the inside of the pole grip, there is now a guide recess 49 in the body of the fixing block 6, which to some extent also forms a through-opening 62 for the locking pin 7 in the fixing block 6. This guide recess 49 widens towards the inside of the pole grip at the encircling shoulder 13 into a recess 8 with a slightly larger inner diameter. The recess 8 then extends inward up to the back side 26 of the fixing block. That is, the recess 8 is designed as a through hole passing through the fixing block 6.
In which a locking pin 7 is movably supported.
The locking pin 7 has a front region 9 which projects with its tip 10 into the insertion slot 43 and limits the region 15 for the retaining ring 42 somewhat upwards. The pin 7, which is designed here as a stainless steel metal pin, then has a circumferential flange 11 immediately adjacent to the front region 9. The front area and the flange 11 have a circular cross-section.
Immediately inwardly of this flange 11 is a rear region 12 of the pin 7, which in turn has a smaller outer diameter than the flange 11. The outer diameter of the rear region 12 can be, for example, the same as the outer diameter of the front region 9, but can also be slightly smaller, as is shown here in the drawing.
A helical spring 48 is arranged in the hollow space between the inner wall of the recess 8 and the outer surface of the rear region 12, said helical spring being tensioned against the closing bolt 40 which is pushed into the recess 8 from the rear side 26 and is fixed thereto. The coil spring 48 is therefore located between the inner surface of the closing bolt 40 and the circumferential collar 11, so that a force acting on the pin 7 is generated toward the retaining projection 14. The stop of the pin 7 can either be provided by the shoulder 13, but it is also possible that the stop is provided by the contact of the tip 10 of the locking pin on the retaining projection. The closing bolt has a circumferential rib 24 which engages in a corresponding circumferential groove 23 in the opening 8. After the pin 7 and the helical spring 48 have been pushed into the fastening block 6 from behind, the closing bolt 40 can therefore be pushed into and fastened in the fastening block 6 in a simple and as self-locking manner as possible. Additionally or alternatively, it can also be glued.
In this case, the tip 10 of the locking pin 7 is formed in a convex hemispherical shape. Thus, the movable position of the locking pin 7 is tensioned towards the retaining projection 14 by the helical spring 48.
With regard to this construction, the following facts are important here in particular: the direction of movement 47 of the locking pin 7 towards the retaining projection 14 is at an angle of less than 90 degrees to the upwardly oriented pole axis 29
Generally, angle
The system proposed here is also advantageously modular. In other words, there is a fixing block 6 which is immovably fixed on the pole grip, to be precise via the transverse pins 27 and 28 already mentioned. The modular construction is best seen in the exploded view of fig. 8. The recess 4 in the
The key insertion part is the fastening block 6 already described above. The holding block is preferably made of hard plastic and has a transverse recess 20, where material for structural functions is not required at all. The guide cylinder 21 is designed for guiding the locking pin 7.
The fixing block 6 can be pushed from above into the recess 4 between the respective lateral wall regions 58, wherein the guide step 60 and the corresponding counter surface 61 in the recess ensure precise positioning of the fixing block in the crown.
The lower transverse pin 28 can then be pushed laterally, so that the fixing block 6 is fixed in the shank.
In the next step, the upper cap 33 is introduced. On the one hand, the cap 33 has a cutout 37 on the hand side; the upper region of the fixing block 6 is located in this cutout. On the other hand, the covering cap 33 has two downwardly oriented strip-shaped retaining arms 34, which are provided with laterally extending retaining openings 35 on their lower end, next to the precisely matching guide step 59. Outside the two partition walls 50 of the handle body, between which partition walls 50 the fixing block 6 is located, the fixing arms 34 are pushed down through the slits 63 into the handle body until the fixing openings 35 are coaxially oriented with the corresponding through holes 51. If the fixing block 6 is inserted correctly, the through-hole 51 is always already aligned with the through-hole 18 of the upper portion of the fixing block 6.
In order to ensure the fastening of the covering cap 33 with the concave inner region 36 provided with the rib 64 and the transverse rib 39 provided on the tip on the inside, the crown has a front fastening projection 38 with the locking projection 56 at the front tip. The tip of the covering cap 33 can now be pushed over the projection 38 and locked there. The upper transverse pin 27 can then be pushed through the openings 51, 35 and 18, so that the fixing block 6 is finally fixed in the crown, and likewise the covering cap 33.
