TECHNICAL FIELD
[0001] The present invention relates to a pole handle for, for example, a hiking pole, a trekking pole, a ski pole, or a Nordic walking pole. Furthermore, the present invention relates to a pole with such a pole handle and a method for assembling such a pole handle. STATE OF THE ART
[0002] From the prior art, for example from DE 299 06 612 U1, walking stick handles are known which are gripped by the user from a direction perpendicular to the longitudinal axis of the stick. The contours of the walking stick handle are designed in such a way that they are suitable for a sequential arrangement of the fingers of a user's hand. When a force is applied from above, a projection serves as a downward support for the index finger. A walking stick in which a knob forms the handle is disclosed in DE 10 2006 008 066 A1. The knob is mounted eccentrically on the stick shaft. This walking stick handle is only suitable for gripping from above.
[0003] Further walking stick handles with an ergonomic design of the handle head are known from EP-A-2 168 641.
[0004] In such handle constructions, the loops can be adjustably attached using different mechanisms, see for example EP-A-1 848 298, WO-A-2018 / 166854, EP-A-1 819 406.
[0005] US-A-2019216186 describes an ergonomic handle for a mobility device, comprising a central gripping portion, the lower portion of which flares outwardly to form a support ledge for an ulnar portion of a user's hand when the hand grips the central column gripping portion, and which extends substantially perpendicular to a longitudinal axis of the central column gripping portion, surrounding the lower portion of the gripping portion, the handle having a slotted cavity bisecting the support ledge and extending upwardly into the central column gripping portion, and the support ledge having a sloped ledge portion sloped downwardly at a rear portion of the support ledge. PRESENTATION OF THE INVENTION
[0006] Accordingly, the object of the present invention is to provide an improved and novel pole grip, in particular a pole grip that is as lightweight as possible using as little structural material as possible, yet still provides the necessary stability even under heavy loads. Furthermore, the proposed pole grip should be visually appealing and should be able to externally demonstrate the technical functionality of the lightweight construction.
[0007] Specifically, it is a matter of proposing a pole handle, in particular for a ski pole, cross-country ski pole, trekking pole or Nordic walking pole, with a head area and a grip area, as well as an axial recess open at the bottom on one side to accommodate a pole tube.
[0008] According to the invention according to a first aspect, such a pole handle is characterized in particular in that the pole handle has a core made of the actual structure-forming material (for example and preferably made of a thermoplastic material such as in particular polyamide, polycarbonate, polypropylene, polyethylene or mixtures thereof, optionally (glass) fiber reinforced), wherein the core has at least partially a first, left side wall and a second, right side wall in the interior of the handle. In other words, in the core, in the head region, there is a cavity extending essentially along the running direction, preferably approximately horizontally or rising slightly forward in the running direction, which is delimited on the left side by the first side wall and on the right side by the right side wall.
[0009] The two side walls are connected at the top by a cover surface, with the side walls and cover surface enclosing a cavity, and the first, left-hand side wall and the second, right-hand side wall in the head area laterally delimiting the cavity. Both side walls each have at least one or preferably two openings in a direction transverse to the longitudinal axis of the pole handle and transverse to the running direction when used as intended. The openings each form a breakthrough area, i.e., a cross-sectional area of the respective through-opening.
[0010] The individual opening area of at least one of the openings, preferably of the majority or all of the openings, is more than 10 mm 2< , in particular more than 15 mm 2< , in particular in the range of 10-50 mm 2< . Alternatively or additionally, the total area of the openings on at least one or both sides, ie in a side wall, of the handle is more than 10 mm 2< , preferably more than 15 mm 2< , or more than 20 mm 2< , in particular in the range of 10-50 mm 2< .
[0011] The design with the aforementioned cavity, the side walls, and the openings in these side walls allows for a stable construction of an elongated cavity extending in the direction of travel within the handle head, without compromising stability even under heavy loads. The webs of this, for example, organic, structure ensure great stability, and the proposed construction can also be easily implemented using conventional processes (injection molding) for the core of the pole handle.
[0012] A first preferred embodiment is characterized in that webs are formed between the openings or the openings are formed by a lattice structure with openings.
[0013] At least one or more of the openings can be in the form of polygons, with possibly rounded corners, e.g. in the form of triangles, quadrilaterals (kite, rhombus, square, rectangle, trapezoidal shape, e.g. parallelogram, trapezoid).
[0014] Typically, the cover surface is solid or grid-shaped. If the cover surface is grid-shaped with full openings, the attachment described below or a separate attachment or coating preferably also covers the surface of the cover surface to prevent the penetration of dirt or similar substances.
[0015] The pole handle preferably has at least one attachment, preferably detachably attached to the core, which partially encloses the core in the head region of preferred masses in the circumferential direction, and which at least partially, preferably completely, covers the openings and / or recesses in the cover surface on the outside. The attachment is preferably non-positively and / or positively attached to the core and / or is positively attached to a loop fastening element likewise embedded in the handle head, or at least contributes to its guidance. For example, it can be two attachments attached to each side, or else a single attachment that grips around the front tip like a clamp and rests against it laterally.
[0016] The attachment is typically and preferably made of a transparent or translucent thermoplastic material, for example polyamide, polycarbonate, polyacrylate (eg PMMA), POM or a mixture of such materials, so that the internal structure is visible.
[0017] The pole handle, including the head and grip areas, preferably has a hard core made of a thermoplastic material and a soft material, such as foam or cork, arranged on top of it in the grip area. The hard core made of a thermoplastic material can have a circumferential recess in the grip area, in which a corresponding foam or cork sheath is arranged. This not only further reduces weight but also makes the handle more comfortable to grip.
[0018] The casing can be made of foam (e.g. EVA), cork, or a composite material, such as wood, raffia, textile, fleece, metal, or a combination of such materials.
[0019] To enable the assembly of such constructions, the hard core can be separated in the lower grip area, i.e., in the area where the axial recess for a pole tube is provided, i.e., have a circumferential slot. Thus, the two-part hard core of the handle can be assembled with the casing by placing the upper or lower section of the hard core in front, sliding on the circumferential casing, and inserting the other section of the hard core into the other free opening in the casing, and then connecting the parts together, e.g., by gluing.
[0020] This proposed design can also be used to provide pole handles of different sizes and shapes in a quasi-modular manner. For example, it is possible to vary the length of the handle section by providing the same head section and upper hard core, and lower hard core sections of different lengths. Then, a sheath of the desired length is combined with a lower hard core section of the desired length, always with the same upper hard core.
[0021] Furthermore, it is possible, in addition to or independently of this, to design the sheath with a different shape while maintaining the same hard core. This allows a whole series of different handles to be provided while maintaining the same hard core by simply using different sheaths. The different sheaths can vary in terms of material and / or shape.
[0022] Particularly preferred within a handle series is to utilize all possible variations, for example by having a single hard core upper section with a handle head, which is always the same, and lower hard cores of different lengths depending on the desired length of the handle area, as well as sheaths of different lengths made of different materials and with different shapes. Alternatively, the upper sections with handle head and hard core area can have different lengths and be combined with lower, hard core areas, either of the same length and shape or of different lengths and shapes. In this way, even user-specific, customized combinations can be provided with comparatively low production effort, which opens up interesting possibilities, especially with today's possibilities of online shipping directly from the production site to the customer.
[0023] The pole handle with a pole longitudinal axis and a front pole grip area pointing in a running direction and a rear pole grip area oriented opposite to the running direction, as well as a wrap-around area and a curved head area adjoining the wrap-around area, wherein the wrap-around area has an upper wrap-around area adjacent to the head area and a lower wrap-around area facing away from the head area, typically has a grip nose in the head area, which in the front pole grip area merges into the upper wrap-around area essentially without a step, wherein the grip nose in the front pole grip area is designed in a projection projecting beyond the wrap-around area in the running direction.
[0024] The overhang typically amounts to more than approximately 50% of the average extent of the gripping area in the direction of travel. Typically, a sectional plane of the head area, which is defined by a transverse axis of the head area arranged transversely to the longitudinal axis of the pole and transversely to the direction of travel, and a forwardmost tip of the grip nose, is angled at an obtuse angle of between 90 and 135 degrees from the longitudinal axis of the pole.
[0025] The handle head preferably projects beyond the grip area in a front region. For better grip, the handle head has at least one elevation on its front underside, preferably approximately halfway between the front edge of the grip area and the tip of the handle head. Further preferably, the underside and optionally at least partially also an area that extends somewhat laterally to the rear are made of a particularly grip-friendly material. Typically, the core of the handle head consists of a hard thermoplastic material, such as polyamide, polycarbonate, polyethylene, polypropylene, or mixtures or glass fiber reinforced thereof. A softer elastomer material can be provided in the lower region of the handle head as a grip-friendly material, which then preferably also provides the aforementioned elevation.The entire core of the handle or at least the upper area with the handle head can be made from a single material, or in a 2K process with an elastomer insert, particularly on the underside of the handle head.
[0026] The upper side or cover surface as well as a cover section of the loop fastening element can also be formed from a grip-friendly elastomer material or at least with a coating of a grip-friendly elastomer material.
[0027] The attachment can be designed as a clamp with two lateral arms, wherein the arms of this clamp virtually encompass the handle head from the front, and wherein the arms extend from a front wall of the attachment backwards to the rear area of the head area of the pole handle and thereby partially cover the side walls and the openings arranged therein, preferably completely, on the outside.
[0028] In this case, each of the lateral arms preferably has at least one first means for a force-fitting and / or form-fitting connection to the core and preferably additionally has at least one second means for a force-fitting and / or form-fitting connection to or at least for guiding, preferably also for securing against loss, a coupling element, wherein at least the second means is preferably a latching means which latches into a latching recess or on a latching extension of a latching structure in the core, wherein furthermore preferably a projection formed by the coupling element engages in a guiding contour in the coupling element, in particular for a tilting movement of the coupling element, but also holds the coupling element in the handle head.
[0029] Both the first, left side wall and the second, right side wall can each have at least three openings in the head area in a direction transverse to the longitudinal axis of the pole handle and transverse to the running direction.
[0030] The first side wall and the second side wall preferably each have at least two or three openings separated from one another by a web, wherein the webs extend from the cover surface of the pole handle downwards in the direction of the handle area and are preferably arranged substantially parallel to the pole handle longitudinal axis or at an angle to the pole handle longitudinal axis.
[0031] The webs are preferably aligned inclined with respect to the pole handle longitudinal axis, wherein webs arranged further forward in the running direction are preferably inclined from bottom to top towards the front, in particular preferably at an angle with respect to the pole handle longitudinal axis of 20-80°, or in the range of 30-60°, and webs arranged further back in the running direction are inclined from bottom to top towards the rear, in particular preferably at an angle with respect to the pole handle longitudinal axis (S) of 10-70°, or in the range of 20-60°.
[0032] The openings in the two side walls are preferably mirror-symmetrical with respect to a plane spanned by the longitudinal axis of the pole handle and the running direction.
[0033] The side walls are further preferably offset in an upper region of the head region with respect to a lower region of the head region inwards towards the cavity, whereby a shoulder is formed between the upper region of the head region and the lower region of the head region, which shoulder partially surrounds the head region in the circumferential direction and on which the attachment rests at least partially, wherein preferably by the shape of the attachment and its position in this offset region a substantially continuous and closed surface of the handle region is formed, apart from gaps between components.
[0034] The bars typically extend from the top surface of the pole handle downwards towards the grip area to the partially circumferential shoulder.
[0035] A further preferred embodiment is characterized in that the attachment is at least partially, preferably completely transparent or translucent, so that the openings in the core are visible from the outside. The pole handle can have a central recess on the rear side in the head region, which is delimited at the top by a cover surface, in which recess a loop fastening element with a hand strap attached to the loop fastening element is received in a rear region of the head region, wherein the loop fastening element preferably has an opening which is aligned with an opening in the side walls, so that the loop fastening element, when viewed through the opening in the side walls in a rest position, is essentially not visible from the outside.
[0036] The pole handle according to the invention further preferably has, between the cover surface and a lower region of the handle head on the back of the handle head, two lateral curved or angled webs, between which a loop fastening element as described above is preferably arranged.
[0037] Furthermore, the pole handle can have an attachment detachably attached to the core, which partially encloses the core in the head region in the circumferential direction, and which at least partially, preferably completely, covers the openings and / or recesses in the cover surface, including the opening formed by the webs, on the outside. The attachment is preferably fastened to the core in a force-fitting and / or form-fitting manner and / or is fastened to a loop fastening element likewise embedded in the handle head, with areas of the attachment engaging behind the webs on the inside and, if necessary, engaging in a guiding manner in curved recesses of a loop fastening element. The use of additional fastening elements can thus be dispensed with.
[0038] The present invention further relates to a method for assembling a pole handle as set out above, which is particularly characterized in that the hand strap is attached to the loop fastening element with a free end and is then inserted as a module into the central recess and tiltably fastened in the handle head via a transverse pin. Preferably, before or after inserting the loop fastening element, an attachment is pushed on and fastened to the handle head, preferably from the front or side, and preferably in a self-locking manner. As a result, the attachment is additionally secured to the handle head via the loop fastening element or via this attachment or regions thereof, and is preferably additionally guided for the tilting movement.
[0039] Last but not least, the present invention relates to a pole, in particular a ski pole, cross-country ski pole, or Nordic walking pole, with a pole handle as set out above or mounted as set out above.

[0042] In a rest position X1, in which the loop fastening element is embedded in the surface contour of the handle head and in which the size of the hand strap cannot be adjusted, the loop fastening element can be tilted upwards about the rotation axis into an adjustment position X2, and in this adjustment position X2 the size of the hand strap can be adjusted.
[0043] This provides a simple design that is particularly advantageous with regard to assembly, repair, and replacement of components. It ensures excellent retention of the strap in the rest position while still allowing easy length adjustment of the hand strap in the adjustable position. The strap fastening element can be prefabricated as a module and installed together with the hand strap as a whole into a corresponding handle head. This also optimizes production processes and inventory management, as such a unit can be used for various models with regard to further design of the handle.A first preferred embodiment is characterized in that the loop fastening element has a through-opening through which the loop band of the hand strap is led out of the pole handle, is guided around the user's hand, and passes through the same through-opening with the free end through the loop fastening element, wherein preferably the free end of the loop band is guided behind this through-opening downwards around the loop fastening element around a deflection area and is then led out of the handle head below the loop as a free loop end.
[0044] This loop guide allows for good clamping and also offers advantages in terms of modularity, as the prefabricated unit consisting of loop fastening element and hand strap can be easily assembled, especially when one end of the loop is attached to the loop fastening element.
[0045] In the rest position, the loop band is preferably clamped between a bottom side of the loop fastening element and an opposite bottom of the central recess.
[0046] Preferably, means are arranged in the clamping area and / or in the deflection area to prevent the size of the hand strap from being adjusted.

[0056] Furthermore, the loop fastening element can have means on its front surface in the transition to the cover section (which, when in use, forms the surface of the handle head in the rest position X1) which ensure a seal, in particular in the form of a projection and / or a sealing lip.
[0057] The pole handle can also have at least one, preferably clamp-shaped, attachment that is positively and detachably connected to the loop fastening element and / or to the core. This can, for example, be two attachments attached to each side.In the case of a clamp-shaped attachment, this can have two side walls which converge in a front wall in the running direction and are connected downwards in a front region by a base, wherein the side walls each have a free end directed rearwardly opposite the running direction, on which end a locking pin is arranged, and wherein the locking pins each engage in a curved guide channel arranged on opposite side walls of the loop fastening element, whereby the loop fastening element is guided in the central recess of the pole handle during a tilting movement of the loop fastening element, and wherein preferably the at least one guide channel is formed along the curvature of a cover section of the loop fastening element.

A softer elastomer material can be provided in the lower region of the handle head as a grip-friendly material, which then preferably also provides the aforementioned elevation.The entire core of the handle or at least the upper area with the handle head can be made from a single material, or in a 2K process with an elastomer insert, particularly on the underside of the handle head.
[0088] The upper side or cover surface as well as a cover section of the loop fastening element can also be formed from a grip-friendly elastomer material or at least with a coating of a grip-friendly elastomer material.
[0089] The present invention further relates to a method for assembling a pole handle as set out above, which is characterized in that the hand strap is attached to the loop fastening element with a free end and is then inserted as a module into the central recess and tiltably fastened via a transverse pin in the handle head. Preferably, before or after inserting the loop fastening element, at least one attachment is preferably pushed on, preferably from the side or from the front, and fastened to the handle head, preferably in a self-locking manner. As a result, the attachment is additionally secured to the handle head via the loop fastening element, or the loop fastening element via this attachment, or regions thereof. Preferably, the loop fastening element is additionally guided by an engagement of the attachment for the tilting movement.
[0090] Last but not least, the present invention relates to a pole, in particular a ski pole, cross-country ski pole, or Nordic walking pole, with a pole handle as set out above or mounted as set out above.
[0091] Alternatively or additionally, the present invention relates to a pole handle with the following properties: A pole handle, in particular for a ski pole, cross-country ski pole, trekking pole or Nordic walking pole, with a head area and a grip area, as well as an axial recess open on one side downwards for receiving a pole tube.
[0092] In this case, such a pole handle is characterized in particular in that the pole handle has a core made of the actual structure-forming material (for example and preferably of a thermoplastic material such as in particular polyamide, polycarbonate, polypropylene, polyethylene or mixtures thereof, optionally (glass) fiber reinforced), wherein the core has at least partially a first, left side wall and a second, right side wall in the interior of the handle.
[0093] The two side walls are connected at the top by a cover surface, with the side walls and cover surface enclosing a hollow space, and the first, left side wall and the second, right side wall in the head area laterally delimiting the hollow space. Both side walls each have at least one or preferably two openings in a direction perpendicular to the longitudinal axis of the pole handle and perpendicular to the running direction when used as intended.
[0094] The individual opening area of at least one of the openings, preferably of the majority or all of the openings, is more than 10 mm 2< , in particular more than 15 mm 2< , in particular in the range of 10-50 mm 2< . Alternatively or additionally, the total area of the openings on at least one or both sides, ie in a side wall, of the handle is more than 10 mm 2< , preferably more than 15 mm 2< , or more than 20 mm 2< , in particular in the range of 10-50 mm 2< .
[0095] The design with the side walls and the openings in these side walls allows for a stable, elongated cavity inside the handle head without compromising stability, even under heavy loads. The webs of this, for example, organic structure ensure great stability, and the proposed construction can also be easily realized using conventional processes (injection molding) for the core of the pole handle.
[0096] A first preferred embodiment is characterized in that webs are formed between the openings or the openings are formed by a lattice structure with openings.
[0097] At least one or more of the openings can be in the form of polygons, with possibly rounded corners, e.g. in the form of triangles, quadrilaterals (kite, rhombus, square, rectangle, trapezoidal shape, e.g. parallelogram, trapezoid).
[0098] Typically, the cover surface is solid or grid-shaped. If the cover surface is grid-shaped with full openings, the attachment described below or a separate attachment or coating preferably also covers the surface of the cover surface to prevent the penetration of dirt or similar substances.
[0099] The pole handle preferably has at least one attachment, preferably detachably attached to the core, which partially encloses the core in the head region of preferred dimensions in the circumferential direction and which at least partially, preferably completely, covers the openings and / or recesses in the cover surface on the outside. The attachment is preferably non-positively and / or positively attached to the core and / or positively attached to a loop fastening element also embedded in the handle head. For example, it can be two attachments, each attached laterally.
[0100] The attachment is typically and preferably made of a transparent or translucent thermoplastic material, for example polyamide, polycarbonate, polyacrylate (eg PMMA), POM or a mixture of such materials, so that the internal structure is visible.
[0101] The pole handle, including the head and grip areas, preferably has a hard core made of a thermoplastic material and a soft material, such as foam or cork, arranged on top of it in the grip area. The hard core made of a thermoplastic material can have a circumferential recess in the grip area, in which a corresponding foam or cork sheath is arranged. This not only further reduces weight but also makes the handle more comfortable to grip.
[0102] The casing can be made of foam (e.g. EVA), cork, or a composite material, such as wood, raffia, textile, fleece, metal, or a combination of such materials.
[0103] To enable the assembly of such constructions, the hard core can be separated in the lower grip area, i.e., in the area where the axial recess for a pole tube is provided, i.e., have a circumferential slot. Thus, the two-part hard core of the handle can be assembled with the casing by placing the upper or lower section of the hard core in front, sliding on the circumferential casing, and inserting the other section of the hard core into the other free opening in the casing. The parts are then joined, e.g., glued.
[0104] This proposed design can also be used to provide pole handles of different sizes and shapes in a quasi-modular manner. For example, it is possible to vary the length of the handle section by providing the same head section and upper hard core, and lower hard core sections of different lengths. Then, a sheath of the desired length is combined with a lower hard core section of the desired length, always with the same upper hard core.
[0105] Furthermore, it is possible, in addition to or independently of this, to design the sheath with a different shape while maintaining the same hard core. This allows a whole series of different handles to be provided while maintaining the same hard core by simply using different sheaths. The different sheaths can vary in terms of material and / or shape.
[0106] Particularly preferred within a handle series is to utilize all possible variations, for example by having a single hard core upper section with a handle head, which is always the same, and lower hard cores of different lengths depending on the desired length of the handle area, as well as sheaths of different lengths made of different materials and with different shapes. Alternatively, the upper sections with handle head and hard core area can have different lengths and be combined with lower, hard core areas, either of the same length and shape or of different lengths and shapes. In this way, even user-specific, customized combinations can be provided with comparatively low production effort, which opens up interesting possibilities, especially with today's possibilities of online shipping directly from the production site to the customer.
[0107] The pole handle with a pole longitudinal axis and a front pole grip area pointing in a running direction and a rear pole grip area oriented opposite to the running direction, as well as a wrap-around area and a curved head area adjoining the wrap-around area, wherein the wrap-around area has an upper wrap-around area adjacent to the head area and a lower wrap-around area facing away from the head area, typically has a grip nose in the head area, which in the front pole grip area merges into the upper wrap-around area essentially without a step, wherein the grip nose in the front pole grip area is designed in a projection projecting beyond the wrap-around area in the running direction.
[0108] The overhang typically amounts to more than approximately 50% of the average extent of the gripping area in the direction of travel. Typically, a sectional plane of the head area, which is spanned by a transverse axis of the head area arranged transversely to the longitudinal axis of the pole and transversely to the direction of travel, and a forwardmost tip of the grip nose, is angled at an obtuse angle of between 90 and 135 degrees from the longitudinal axis of the pole.
[0109] The attachment can be designed as a clamp with two lateral arms, wherein the arms of this clamp virtually encompass the handle head from the front, and wherein the arms extend from a front wall of the attachment backwards to the rear area of the head area of the pole handle and thereby partially cover the side walls and the openings arranged therein, preferably completely, on the outside.
[0110] In this case, each of the lateral arms preferably has at least one first means for a force-fitting and / or form-fitting connection to the core and preferably additionally has at least one second means for a force-fitting and / or form-fitting connection to a coupling element, wherein at least the second means is preferably a locking means which locks into a locking recess or on a locking extension of a locking structure in the core.
[0111] Both the first, left side wall and the second, right side wall can each have at least three openings in the head area in a direction transverse to the longitudinal axis of the pole handle and transverse to the running direction.
[0112] The first side wall and the second side wall preferably each have at least two or three openings separated from one another by a web, wherein the webs extend from the cover surface of the pole handle downwards in the direction of the handle area and are preferably arranged substantially parallel to the pole handle longitudinal axis or at an angle to the pole handle longitudinal axis.
[0113] The webs are preferably aligned inclined with respect to the longitudinal axis of the pole handle, wherein webs arranged further forward in the running direction are preferably inclined from bottom to top towards the front, in particular preferably at an angle with respect to the longitudinal axis of the pole handle of 20-80°, or in the range of 30-60°, and webs arranged further back in the running direction are inclined from bottom to top towards the rear, in particular preferably at an angle with respect to the longitudinal axis of the pole handle of 10-70°, or in the range of 20-60°.
[0114] The openings in the two side walls are preferably mirror-symmetrical with respect to a plane spanned by the longitudinal axis of the pole handle and the running direction.
[0115] The side walls are further preferably offset in an upper region of the head region with respect to a lower region of the head region inwards towards the cavity, whereby a shoulder is formed between the upper region of the head region and the lower region of the head region, which shoulder partially surrounds the head region in the circumferential direction and on which the attachment rests at least partially, wherein preferably by the shape of the attachment and its position in this offset region a substantially continuous and closed surface of the handle region is formed, apart from gaps between components.
[0116] The bars typically extend from the top surface of the pole handle downwards towards the grip area to the partially circumferential shoulder.
[0117] A further preferred embodiment is characterized in that the attachment is at least partially, preferably completely transparent or translucent, so that the openings in the core are visible from the outside. The pole handle can have a central recess on the rear side in the head region, which is delimited at the top by a cover surface, in which recess a loop fastening element with a hand strap attached to the loop fastening element is received in a rear region of the head region, wherein the loop fastening element preferably has an opening which is aligned with an opening in the side walls, so that the loop fastening element, when viewed through the opening in the side walls in a rest position, is essentially not visible from the outside.
[0118] The pole handle according to the invention further preferably has, between the cover surface and a lower region of the handle head on the back of the handle head, two lateral curved or angled webs, between which a loop fastening element as described above is preferably arranged.
[0119] Furthermore, the pole handle can have an attachment detachably attached to the core, which partially encloses the core in the head region in the circumferential direction, and which at least partially, preferably completely, covers the openings and / or recesses in the cover surface, including the opening formed by the webs, on the outside. The attachment is preferably fastened to the core in a force-fitting and / or form-fitting manner and / or is fastened to a loop fastening element likewise embedded in the handle head, with areas of the attachment engaging behind the webs on the inside and, if necessary, engaging in a guiding manner in curved recesses of a loop fastening element.

[0122] In the Figures 1-14 A first preferred embodiment of the pole handle 1 according to the invention is shown. The same reference numerals designate the same elements according to the list of reference numerals.
[0123] The stick handle 1 (cf. Figure 1 )has a head region 2 or a grip head and a grip region 3. The pole grip 1 is essentially constructed from the following basic elements, namely a pole grip core 1a (typically made from a plastic material in an injection molding process in one or more components), an attachment element 7, which is pushed or placed onto the core 1a in the head region 2, or the grip nose 2a, from the front and partially clasps the front upper grip region of the head region 2, and a coupling module consisting of a loop fastening element 5 with a hand strap 4 attached thereto, which in the present embodiment is adjustable in size. The core 1a of the pole grip is, as shown in Figure 2 and Figure 12recognizable, a one-piece or multi-part, multi-component component which typically has a surface coating made of a grip-friendly material in the grip area 3, or a corresponding sheath, typically made of a grip foam or natural material, e.g. cork. The core 1a of the pole grip can also be divided transversely to the pole axis in order to, for example, mount alternative grip materials in the form of sleeves, which can make up a portion of the gripping surface. At the lower end of the grip area 3, the pole grip 1 or the core 1a of the pole grip 1 has a shoulder 17 directed backwards, opposite to the running direction L, or towards the pole grip user when in use, on which shoulder the user can support the ball of his hand when gripping the pole grip 1 in the circumferential direction U in the lower grip area.
[0124] The core 1a of the pole handle 1 has a central axial pole handle recess 16 in the form of a blind hole from below, which is typically limited upwards towards the handle head and is arranged essentially along the pole handle longitudinal axis S. The axial recess 16 serves to receive and fasten a pole tube (not shown) or a tube section of a pole, in particular a ski pole, cross-country pole, trekking pole or a Nordic walking pole.
[0125] The head region 2 of the pole handle 1 has a front region 2a or a grip nose pointing in the running direction L, wherein the running direction L is arranged essentially perpendicular to the pole handle longitudinal axis L and points away from the user of the pole handle 1. The head region 2 of the pole handle 1 is covered by the user's palm when the user supports themselves on the pole handle from above. In the front region 2a of the head region 2, the pole handle 1 has a raised portion 40 below the grip head 2 in the transition region to the grip region 3. This serves to facilitate gripping, particularly when the grip head is grasped from behind and above and the fingers enclose this lower front region.It is then possible, for example, to place the index finger in the depression in front of this elevation 40 and the middle finger in the depression behind this elevation 40, or shifted one finger position further, the middle finger in the depression in front of the elevation 40 and the ring finger in the depression behind the elevation 40.
[0126] The head area 2 of the pole handle 1 has a central recess 11 on the top side from the rear, for receiving a loop fastening element 5 for a hand strap 4 (compare for example Figure 2 or Figure 7 ). This central recess 11 extends from the rear region 2b of the head region 2 to the front region 2a. The core 1a is thus partially hollow in the head region 2.
[0127] The core 1a has, viewed in the direction of travel L, a first, left side wall 14a and a second, right side wall 14b. These are open to the rear and converge in a front wall 14c in the front region 2a of the pole handle 1. In the upper and front handle region 2a, the side walls 14a, 14b are partially offset inwardly, forming a shoulder 21 that partially extends in the circumferential direction U. The core 1a has several openings 12a-12f, 15 in the said side walls 14 in the head region 2. In the illustrated embodiment, these are realized by a first opening 12a, a second opening 12b and a third opening 12c in the first, left side wall 14a and by a fourth opening 12d, a fifth opening 12e and a sixth opening 12f in the second, right side wall 14b of the core 1a.In this case, two openings 12a, 12d (front), 12b, 12e (in the middle), and 12c, 12f (rear) are located opposite each other in the head region 2 of the core 1a. The openings each form a breakthrough area 12, i.e., a cross-sectional area of the respective through-opening.
[0128] The front wall 14c has in the illustrated embodiment of Fig. 2 a seventh breakthrough 15.
[0129] The openings 12a-12f in the side walls 14a, 14b are each separated from one another by webs 13a-13d and the frontmost webs 13e and 13f in the respective side walls 14a, 14b. The webs 13a-13f extend essentially from the top or cover surface 6 of the core 1a downwards in the direction of the grip region 3 up to the partially circumferential shoulder 21. The cover surface 6, which is closed in this embodiment, is correspondingly supported by a plurality of webs 13, and the side walls and the cover surface enclose a cavity 42 running in the running direction, which merges rearwardly into the recess 11 and is closed at the front by the front wall 14c.
[0130] These webs can be aligned essentially parallel to the pole's longitudinal axis, but, as shown in this exemplary embodiment, can preferably be oriented as bionic structures adapted to the typical loading directions. Thus, the rear webs 13b, 13d are inclined from bottom to top, and the front webs 13a, 13c are inclined from bottom to top, each typically at an angle of 30-60° to the rear relative to the pole's longitudinal axis, and at an angle of 20-45° to the front relative to the pole's longitudinal axis. This results in a kind of lattice or mesh structure of the core 1a in the upper head region 2 to support the top surface 6.
[0131] Furthermore, the cover surface 6 is supported rearwardly on both sides by an arcuate web 41 which connects the cover surface 6 to the lower part of the core and laterally encloses and guides the loop fastening element 5.
[0132] The surface of the head area 2 of the pole handle 1 and thus the grip surface from above (cf. Figure 11 ) is formed partly by the upper side or cover surface 6 of the core 1a, partly by the attachment element 7 and partly by the loop fastening element 5. The curved upper side or the cover section 25 of the loop fastening element 5 in the rest position or the non-tilted locking position are almost completely integrated into the outer contour of the head area 2. The surface of the head area has a side view when the loop fastening element is removed (see Figure 14 ) via a first step 19 at the transition from the top to the loop fastening element, and via a second step 20 at the transition to the lower handle area, so that the loop fastening element is embedded flush with the surface of the handle head.
[0133] The attachment element 7 encompasses or covers in the head region 2 of the pole handle 1 with the front wall 7c of the attachment element 7, which is designed as a clamp, the front region or the front wall 14c of the core 1a, and with its two arms 7a, 7b extending laterally from the front wall 7c, the flanks or side walls 14a, 14b of the core 1a, as shown in the exploded view of Figure 2 recognizable. The attachment 7 thus encloses with its two side walls 7a, 7b and its front wall 7c on three sides the front area of the handle head and the two lateral areas of the side walls 14. Furthermore, it encloses an area which serves to accommodate a locking structure 35 in the interior of the head area 2 of the core 1a, as in Figure 9 and Figure 10a shown.
[0134] In the front area of the attachment 7, it has a base 7d connecting the two side walls 7a, 7b (cf. Figure 13), which has a recess 7g and delimits the interior in the front area downwards. The bottom 7d extends essentially parallel to the Figure 8 drawn section plane BB, which extends parallel to a longitudinal axis of the head region K1. When the attachment 7 is pushed from the front onto the core 1a in the head region 2 of the pole handle 1, the base 7d slides at least partially from the front into a slot 18 in the locking structure 35 and the attachment 7 locks onto the core 1a of the pole handle 1. This is made possible by a positive connection between a substantially semicircular locking tongue 34 with an undercut on the locking structure 35 inside the head region 2 and the corresponding recess 7g in the base 7d of the attachment (cf. Figure 10a). The recess 7g has a slot-like extension 7k directed in the running direction L to enable the widening of the attachment 7 for locking into place. The recess 7g is delimited towards the rear by two lugs 7h, 7i directed inwards essentially transversely to the longitudinal axis of the side arms 7a, 7b of the attachment towards the interior space 7m. When the clamp-shaped attachment is fitted, the two lugs 7h, 7i engage under the two opposite front openings 12a, 12d in the slot 18 in the head region 2 of the core 1a and lock into the undercut behind the locking tongue 34 of the core 1a, each in a locking recess or in the respective undercut.
[0135] Instead of this base 7d with corresponding recess 7g it is also possible (cf. Fig. 10b), to provide on the front wall 7c locking tongues directed rearward in the running direction, for example two such tongues with two laterally outwardly directed projections at the free end, and these can engage in the opening 15 in the handle head and behind it engage behind the webs 13e and 13f in the cavity 42 behind the front wall.
[0136] The openings are each overlapped or covered by a lateral arm 7a, 7b of the attachment. When in place, the front wall 7c and the side walls 7a, 7b of the attachment rest on the shoulder 21 of the core 1a, which surrounds the head region 2 in the front region 2a and on both sides and seamlessly merges with the curvature of the head region 2 into the rear region 2b. The arms 7a, 7b have a concave curvature directed toward the interior space 7m of the attachment 7.
[0137] The cover element 7 serves, among other things, to seal the open, lightweight construction with the webs and thus prevent dirt or similar from penetrating the handle head. On the other hand, it also provides the smoothest and most seamless surface for the handle. The cover element is typically and preferably made of a transparent or translucent thermoplastic material, for example, polyamide, polycarbonate, polyacrylate (e.g., PMMA), POM, or a mixture of such materials, so that the internal structure is visible.
[0138] At the free end of the respective first, left arm 7a or the second, right arm 7b of the attachment, each arm 7a, 7b has a locking hook, locking web, or locking pin 7e, 7f. This locking pin 7e, 7f extends from the respective arm 7a, 7b initially inward, i.e., toward the interior 7m of the attachment 7 and then toward the upper rear. These locking pins 7e, 7f serve to fasten the attachment 7 to the loop fastening element 5 and thus indirectly to fasten the attachment to the core 1a. Furthermore, they have a guiding function for the loop fastening element 5, as described below. The locking pins 7e, 7f engage from the outside through the openings 12c and 12f respectively and then engage behind the curved web 41. In other words, the attachment 7 is pushed on from the front, engages with the locking pins on the inside around the webs 41 and engages further forward with the recess 7g on the locking tongue 34.
[0139] The head region 2 of the pole handle 1 also has a rear region 2b, which faces the pole handle user and in which a hand strap 4 is attached. In the illustrated first embodiment, the hand strap 4 is arranged in the central recess 11 in the head region 2a of the pole handle 1 and in the illustrated embodiment is Figure 5aThe loop fastening element 5, which can be tilted in the direction of the movement indicated, is connected to or coupled to the pole grip 1. In the exemplary embodiment shown, the loop fastening element 5 is designed in a block-shaped manner. The central recess 11 of the pole grip 1 is delimited at the bottom in the core 1a by a base 27 and separated from the upper end of the pole grip recess 16. The hand strap 4 has a loop section 4a which is designed to at least partially enclose a hand or wrist of the pole grip user. The loop section 4a is arranged between a first, free loop end 4c, which protrudes from the interior of the pole grip and can be pulled by hand to reduce the loop width, and a second loop end 4d, which is fastened in or on the loop fastening element 5.
[0140] In the illustrated first embodiment, a deflection section 4b is arranged between the loop section 4a and the first, free loop end 4c, which deflection section is guided around a deflection area 22 of the loop fastening element 5 (compare in particular Figure 2 and Figure 6 ).The second loop end 4d is fastened to a front side 29 of the loop fastening element 5 facing the running direction L by means of a fastening means 10, which in the present embodiment is designed as a screw. By forming a projection 24 extending in the running direction L on the upper front edge of the loop fastening element 5, the second, fastened loop end 4d is covered upwards toward the top of the head region 2a of the pole handle 1 and protected from environmental influences, and the thickness of the loop material fastened in this region is compensated, so that the front surface of the loop fastening element is essentially flush.To guide the loop band to form the loop section 4a, the loop fastening element 5 has a through-opening 26 in the form of a slot-shaped channel, which is arranged essentially parallel to the base surface 35 of the loop fastening element 5, and which, with its longitudinal axis K 2 in the non-tilted or resting state of the loop fastening element 5, is arranged essentially along the longitudinal axis K 1 of the head region of the pole handle. Both loop regions that form the loop section 4a for the hand are guided through this through-opening 26, i.e., both the region to the fastened second loop end 4a and that to the free loop end 4c.
[0141] The loop fastening element 5 according to the illustrated first embodiment of Figures 1-14is arranged in the central handle head recess 11 about a rotation axis or tilting axis D about a pin 9 arranged in a through opening 8, tiltable or pivotable, namely between a rest position X1, as in Figure 5a shown, and a tilt position X2, as shown in Figure 5b The pivoting range is approximately 30-40°. In the resting position, the loop width is fixed, and in the tilted position of the loop fastening element 5, the loop width is adjustable. The loop width in the latter position of the loop fastening element can be reduced by pulling on the first, free end 4a of the hand strap, and can be increased by pulling on the part of the loop section 4a facing the first, free end.
[0142] In the resting position of the loop fastening element 5, the deflection section 4b of the hand strap 4 is clamped between the bottom 27 of the handle head recess 11 and the underside or bottom 5c of the loop fastening element 5. The clamping is achieved here essentially analogously to a labyrinth seal, in the form of a clamping section 23 of the loop fastening element 5, which is designed as a projection 23 directed downwards towards the bottom 27 of the handle head recess 11. In addition to the frictional engagement, there is also, to a certain extent, a positive engagement via one or possibly several clamping edges. The clamping force required to fix the loop is significantly lower due to the labyrinth edge than with a linear line of force, which enables an improved clamping effect with the same clamping force or the same clamping effect with a lower clamping force.For this purpose, the bottom 27 of the handle head recess 11 has a clamping section 27a formed as a step 37 by means of an edge 11b. When the loop fastening element is at rest, the loop band is clamped between its deflection section 4b and the first, free loop section 4a projecting outwards from the through-opening 26, designed as a channel, of the loop fastening element 5, by frictional engagement between the projection 23 and the stepped section 27b of the bottom 27 of the handle head recess 11. The frictional engagement as a result of the deflection of the free end of the loop band after passing through the through-opening 26 downwards and backwards around the loop fastening element, which frictional engagement is located in a deflection area 22 (cf. Figure 14 )can be reinforced by corresponding cross ribs or similar, is correspondingly reinforced by the clamping between clamping projection 23 and step 27b. The latter clamping has the advantage that it can be used under the typical downward load of the hand strap during use due to the corresponding torque applied (clockwise in the illustration according to Figure 4 ) is reinforced.
[0143] As in Figure 2The loop fastening element 5 is shown as a separately formed component that can be attached to a "core body" or core 1a of the pole handle 1. The fastening is achieved by a pin 9, which is inserted into a first through-opening 8a in the left side wall of the pole handle 8b, then guided through a through-opening 38, which extends from a first, left side wall 5a of the loop fastening element 5 to a second, right side wall 5b through the loop fastening element 5, and then guided through a second through-opening 8b in the right side wall of the head region 2a of the pole handle 1. When the loop fastening element 5 is inserted, the longitudinal axis of the through-opening 38 or the longitudinal axis of the pin 9 is arranged essentially transversely to the pole handle longitudinal axis S and transversely to the running direction L.
[0144] In Figure 14The loop fastening element 5 or folding element is shown in detail. The loop fastening element 5 has a curved cover section 25, which has a slightly projecting front edge 39 in the running direction. The cover section 25 or the upper side of the loop fastening element is integrated into the upper side 6 of the pole handle 1 in the rest position and simultaneously forms the rear area 2b of the head area 2 of the pole handle 1. The loop fastening element 5 is additionally captured by the engagement of the locking pins 7e and 7f (see Figure 7a ) into corresponding guide channels 28a and 28b.
[0145] To reduce weight, the loop fastening element can have recesses or windows 32 where a solid material design is not necessary under load considerations. In general, the loop fastening element is preferably made of a thermoplastic material, for example, polyamide, polypropylene, polyethylene, polycarbonate, each optionally reinforced with (glass) fiber, or mixtures of such materials.
[0146] The loop fastening element 5 also has a bottom side 37 which, when inserted into the pole grip recess 11, is directed towards the bottom 27 of the central recess 11 of the pole grip 1 when at rest. Likewise, the loop fastening element 5 has a first, left side surface 5a and a second, right side surface 5b which are arranged parallel to a plane E defined by the grip head longitudinal axis K1 and the pole grip longitudinal axis S, and which extends parallel to the plane shown in Figure 3shown section plane AA.
[0147] Both in the first, left side surface 5a, and in the second, right side surface 5b, a guide channel 28a or 28b is arranged which is curved in accordance with the rotational movement of the loop fastening element and extends parallel to the curvature of the cover section 25, namely from the underside 37 of the loop fastening element 5 (groove open there) over a partial area of the respective side wall 5a, 5b, and not completely up to the front wall 29 of the loop fastening element 5. This respective guide channel 28a, 28b serves, in addition to the aforementioned catching of the element, to guide the loop fastening element 5 during the tilting process about the rotation or tilting axis 9 or around the pin 9. This guidance is achieved by the two lateral locking pins 7e, 7f of the attachment 7 described above, which are also correspondingly curved, engaging or locking into these two guide channels 28a, 28b.This locking connection between the loop fastening element 5 and the attachment 7 connects the attachment 7 to the loop fastening element 5, and thereby also indirectly connects the attachment to the core 1a of the pole handle 1 via the loop fastening element 5. The locking connection thus simultaneously provides a guide function for the rotation of the loop fastening element 5 between the locking position and the adjustment position, as well as a loss protection for the attachment 7 on the core 1a of the pole handle 1.
[0148] In each of the two side surfaces 5a, 5b of the loop fastening element 5, a locking channel 33a, 33b is arranged, into which a locking comb 31a, 31b directed inwards from the side wall 14a, 14b of the core 1a engages in the rest position, i.e., in the non-tilted position of the loop fastening element 5. The locking channels 30a, 30b each run essentially parallel to the bottom surface 37 of the loop fastening element 5. The locking combs 31a, 31b run essentially parallel to the bottom 27 of the central recess 11 of the core 1a.
[0149] In addition, each side wall 5a, 5b of the loop fastening element 5 has a further locking channel 33a, 33b, which intersects the first and second locking channels 30a, 30b at an acute angle. The intersection point of the first locking channel 30a with the third locking channel 33c in the first side wall 5a of the loop fastening element 5 and the intersection point of the second locking channel 30b with the fourth locking channel 33d in the second side wall 5b of the loop fastening element 5 is defined by the through-opening 38 in the loop fastening element 5 and by the receiving channel for the transverse pin 9 for the tiltable connection of the loop fastening element 5 to the pole grip core 1a. Thus, the loop fastening element 5 locks in the non-tilted resting state according to Figure 5a with its first and second locking channel 30a, 30b in the two opposing locking combs 31a, 31b in the core 1a, which, for example, in Figure 6on the second side wall 14b of the core 1a. In order to tilt the loop fastening element 5 forward for the purpose of adjusting the diameter of the hand strap, the loop section 4a of the hand strap 4 is pulled upwards. When tilting the loop fastening element 5 forwards about the rotation / tilt axis or about the cross pin 9, the locking combs 31a, 31b are displaced from the respective corresponding first and second locking channels 30a, 30b, and thus this locking connection is canceled, wherein in the tilted state according to Figure 5b The locking combs 31a, 31b engage the third and fourth locking channels 33a, 33b, respectively, thus establishing a further locking connection. The engagement and disengagement results, on the one hand, in a slight, positively locking fixation of the respective position, but on the other hand also in haptic and, if necessary, acoustic feedback for the user.
[0150] Furthermore, when the loop fastening element 5 is tilted or pivoted, the clamping area 23 of the loop fastening element 5 is lifted from the step section 27a. During the tilting process, the projection 24 on the cover section 25 of the loop fastening element 5 is also pivoted into the central recess 11 of the head section 2.
[0151] The loop fastening element 5 further comprises a front surface 29 directed towards the running direction L, the surface of which extends at an angle of less than 90° to the bottom surface 27 of the loop fastening element 5. A recess 10a is arranged substantially centrally in this front surface 29, which recess serves to receive a fastening means 10 for the second loop end 4d. In the illustrated embodiment of Figure 2 , or Figure 5a, 5bThis fastening element is usually a screw. However, it can also be a rivet, a pin, an adhesive connection, an eyelet in the wrist strap with a hook, or a combination of such fastening elements.
[0152] If the loop fastening element 5 is replaced or dismantled, for example to replace the hand strap, the attachment 7 can first be removed from the core 1a and from the loop fastening element 5, i.e. the locking connection between the locking pins 7e, 7f on the arms 7a, 7b of the attachment 7 and the loop fastening element 5 can be released by spreading the arms 7a, 7b apart. This spreading also releases the locking connection between the locking tongue 34 of the core 1a and the locking lugs 7g, 7h on the base 7d of the attachment 7. Subsequently (or even beforehand), the cross pin 9 can be pressed out of the through-opening 8a in the loop fastening element 5 and out of the through-opening 8 below the head region 2 of the core 1a, for example using a pin with a smaller diameter.By pulling the loop fastening element 5 backwards along the locking comb 31a, 31b, the loop fastening element 5 can be removed from the central recess 11 of the core 1a.
[0153] Alternatively, the transverse pin 9 can first be pressed out of the through-hole 8a in the loop fastening element 5 and out of the through-hole 8 below the head region 2 of the core 1a, for example, using a pin with a smaller diameter. Then, by spreading the arms 7a, 7b apart and pulling the loop fastening element 5 upwards or backwards, the loop fastening element 5 can be removed from the central recess 11 of the core 1a. Subsequently, the attachment 7 is removed from the core 1a, i.e., the locking connection between the locking pins 7e, 7f on the arms 7a, 7b of the attachment 7 is released.
[0154] To assemble the pole grip 1 during manufacture or after replacing or repairing the loop fastening element 5 or the hand strap 4, either the loop fastening element 5 is first inserted into the central recess 11 of the grip head 2 of the pole grip 1 essentially from the rear along the longitudinal axis K1 of the head region 2 and along the locking combs 31a, 31b and fastened to the core 1a of the pole grip 1 by means of the transverse pin 9, as described above, and then, for a further, indirect connection of the loop fastening element 5 to the core 1a of the pole grip 1, the attachment 7 is pushed from the front onto the core 1a of the pole grip 1. Or in the reverse order, first attaching the attachment and then inserting and fastening the loop fastening element 5 in the central recess 11 of the grip head 2 of the pole grip 1.
[0155] In Figure 15 is a variant of the handle according to Figure 4shown. The handle here has a circumferential sheath 43 made of a cork material or a foam material (e.g. EVA) in the grip area. The sheath 43 is inserted into a circumferential recess 44 in the actual area 45 of the hard core material that forms the handle. The sheath 43 fits flush with the contour of the handle all along the edge. This ensures a particularly grip-friendly and lightweight construction. To ensure that such a construction can be easily assembled, the cylindrical area 45 of the hard core material of Figure 3 has a circumferential slot 46, i.e.the handle is formed in two parts with respect to the hard core material, there is an upper region 48 with the head region 2 and the upper part of the region which forms the axial recess 16, and a lower part 49 which, for example, comprises the shoulder 17 and the lower part of the region which forms the axial recess 16.
[0156] Advantageously, the slot 46, as shown in dashed lines in the figure, is designed with a winding profile 47, in particular in such a way that this ensures a certain degree of anti-twist protection and, to a certain extent, can also provide a positive or even frictional connection between the upper and lower parts. In a preferred variant, the winding slot 46 has longitudinal sections 50 of the edges that run along the axis of the stick, as well as transverse sections 51 of the edges that run in the circumferential direction and perpendicular to the axis of the stick. Preferably, the longitudinal edges of the winding slot of the upper and lower parts fit together with virtually no play, or even sliding when in contact, or even deliberately frictionally rubbing, in order to achieve the most precise alignment of the two handle parts with respect to rotation around the stick axis.In a further advantageous manner, the winding slot, in its transverse direction to the pole axis, forms a gap 52 at the transverse edges 51 between the front contact surfaces of the two sleeve sections of the handle parts when the sheath is installed. This prevents over-determination of the handle parts. This design of the slot is advantageous, independent of the other features of the embodiment used here for illustration, and is to be considered in accordance with the invention.
[0157] Such a grip head is assembled by placing the upper section 48 in front of the handle, then sliding the sheath 43 onto the cylindrical section 45 from below, and then sliding the lower section 49 from below into the then exposed lower opening in the sheath 43. The parts are connected to one another by applying adhesives between the sheath and the upper section 48 and the lower section 49. Additionally, connecting means can be provided between the upper section 48 and the lower section 49. Since this section is ultimately fixed by the inserted pole tube, it may be sufficient to provide an adhesive connection from the respective section 48 / 49 to the sheath 43. Analogously, the elastomer section already mentioned above can also be arranged on the underside of the grip head in the area of the elevation 40 in a corresponding recess in the hard core material.Typically, such an elastomer area is not manufactured as a separate component, but rather is simply molded onto the hard core material using a two-component process.
