  • the intended release of the loop 70 from the retaining mandrel is in turn ensured via a release button 18 with corresponding links 77, which the locking pin 7 via the transverse axis 20, which is displaceable in the elongated hole opening 48.
  • FIG Figure 3 A third embodiment is shown in FIG Figure 3 shown.
  • at least the lower region 65 of the holding mandrel is made in one piece and made of the same material as the handle body.
  • the first safety release and the construction of the fastening block 6, the locking pin 7 including the tensioning pin 22 and the spiral spring 23 is analogous to the embodiment 1 described above.
  • an upper region 66 of the holding mandrel 14 is formed from a soft and elastically deformable / flexible plastic.
  • a transition area 67 between the lower area 65 and the upper area 66 is formed from a soft and elastically deformable / flexible plastic.
  • such a handle head is produced in a two-component injection molding process, a different material being used for the area 66 than for the area 65.
  • the loop is shifted slightly upwards on one side and then comes into the area of the upper soft and bendable area 66. Since the upper area 66 is flexible, the loop can then also be made without mechanical safety release with spiral springs by rotating the fastening block 6 about the axis 11.
  • the transition area can be designed differently, different possibilities are in the Figures 3d -1 shown.
  • extension area 68 is a substantially circular cylindrical pin.
  • a somewhat spherical extension can be provided on the extension 68 also at the free end.
  • Figure 4 Another embodiment is shown in Figure 4 shown. As a major difference compared to the embodiment according to Figure 1 It should be emphasized that here essentially the entire mechanism for the retaining mandrel is combined in one unit, which can be assembled beforehand and then inserted into the recess 4 in the pole grip 1 and fastened in this recess 4.
  • An essential element of this design is an additional holding block 82, which is mainly used in the Figures 4 g) and h) is shown separately in two perspective views.
  • This holding block 82 is provided as a carrier for the mandrel block 26.
  • a hollow circular cylinder extension 85 with an axis opening 86 is provided on a surface 87 of the holding block 82 that faces the mandrel block 26.
  • the mandrel block 26 has a corresponding recess 28 which can be pushed onto the hollow circular cylinder extension 85.
  • the mandrel block 26 can then be fastened to the holding block 82 with a screw 88.
  • the mandrel block 26 is then rotatably mounted on the holding block 82.
  • the holding block 82 also has two arms 84, at the ends of which two through openings 83 are provided.
  • This holding block 82 can be connected to the fastening block 6 and the release button 18 with a holding pin 81. This is done by first pushing the release button 16 from above over the fastening block 6, in which the locking pin 7 with the spring 13 can already be inserted with the transverse pin 20.
  • the holding block 82 with the two arms 84 is also pushed on from below until the through openings 92, 83 and 98 are aligned and the holding pin 81 can be pushed in.
  • the V-shaped extension 39a of the fastening block 6 engages in a receiving pocket 94 in the mandrel block 26.
  • the unit formed in this way from the elements 6, 18, 26 and 82 can be almost prefabricated and then inserted into the recess 4 in the pole handle 1 and fastened in this recess 4 via the fastening transverse pin 99.
  • the compression spring 23 with the two spring end caps is pushed onto the eyebolt 22 from below through the handle bore and fixed by means of the hexagon nut 24.
  • the compression spring 23 is pretensioned and the desired release force is thus also adjusted.
  • this unit is then fixed in the recess 4 and its elements are nevertheless movable to the required extent for the release functions and the latching functions.
  • this fourth embodiment works essentially the same as the first embodiment: if the loop 70 is pushed over the retaining mandrel 14 from above, the locking pin 7 moves against the force of the spiral spring 13 into the fastening block 6 , and after the loop 70 has reached the holding area 15, The locking pin 7 pushes itself against the retaining mandrel 14 again and thus locks the loop 70 in the area 15.
  • the safety release also works in the same way as the first exemplary embodiment when the loop 70 is pulled upwards:
  • the force from below on the concave area 10 of the locking pin 7 causes the fastening block 6 to pivot about the axis 81 against the force of the spring 23 (compare in particular Figure 4e , there movement of block 6 counterclockwise), so that the loop 70 is released.
  • the possible lateral safety deflection of the holding mandrel 14 against a controlled triggering force is ensured here by the engagement of the V-shaped extension 39a of the fastening block 6 in the receiving pocket 94 in the mandrel block 26.
  • This receiving pocket 94 has two correspondingly V-shaped flanks 95, and the mandrel block 26 is secured by e.g. If the side pull on the loop is rotated around the axis 88, this can only be done by the flanks 95 of the receiving pocket 94 in the mandrel block 26 sliding on the flanks of the extension 39a of the fastening block 6, i.e. the fastening block 6 upwards against the force of the spring 23 is deflected.
  • the lateral deflection of the mandrel block 26 against this spring force is thus also possible and, after loading, the mandrel block 26 jumps back into its original vertical starting position, also because of this spring force.
  • Figure 5 Another embodiment is shown in Figure 5 shown. It has a similar trigger mechanism as the example according to Figure 4 , but also has a safety release around a second axis of rotation. Specifically, the mandrel block 26 cannot be tilted downward as intended when the hand strap is loaded, but rather backwards slightly when the hand strap is loaded so that the eyelet of the hand strap can just slide out between the locking pin and the retaining mandrel 14. In this way, to a certain extent, a safety release can be guaranteed around all three axes.
  • a replaceable cover is also provided, which allows accessories made of hard plastic, for example a guard for the hand (so-called gate guard, for example for slalom competition and training) to be attached to the pole handle using an adapter piece 111.
  • a guard for the hand for example for slalom competition and training
  • the stick handle according to this exemplary embodiment is shown with a closing cover 114, while in FIG The perspective views in c) and d) this cover is replaced by an insert or an adapter piece 111, typically made of metal, which has an internal thread 120 for a fastening screw, for example for a hand guard (not shown). Typically, the other free end of the handguard is attached to the stick tube directly below the handle body.
  • the cover 114 is shown in the exploded view Figure 5e more recognizable.
  • the cover that is inserted in the illustrations a) and b) is the cover 106.
  • This cover 106 has a cover plate 114 which, when inserted, forms the surface of the upper area of the handle.
  • This cover plate 114 is fastened to the pole handle via a fastening stump 107 which engages in a corresponding blind hole or an exposed area in the handle body and / or in the fastening block 7. At the lower end of this fastening stump 107 there is a transverse through opening.
  • the cover 106 can be fastened in the inserted state with the cross pin 11 in the handle body. Typically, a cane handle with cover 160 so inserted will be sold. If a user would like to attach a hand protector to such a handle, for example, the transverse pin 11 only needs to be removed, the cover 106 removed from the handle head, and the adapter 111 for the hand protector can now be inserted into the recess that has now been released.
  • This insert also has a fastening stump 107, at the lower end of which a transverse through opening 113 is provided for the transverse pin 11.
  • the adapter piece 111 can thus be fastened in the handle head quite analogously to the cover 106.
  • the adapter piece 111 now has a collar or circumferential flange 112 on the upper side, and the fastening stump 107 is designed as a blind hole that is open at the top and has an internal thread.
  • the fastening screw of an accessory can now easily be screwed into this internal thread 120 and the accessory is thus firmly fastened to the handle head without further manipulation.
  • FIG. 5 e) in particular in an overall view with g) it can now also be recognized how in this exemplary embodiment the retaining pin 14 is mounted about two axes of rotation in the sense of a further improved safety release.
  • the mandrel block 26 is in turn fastened rotatably to a holding block 82 via a screw 88.
  • the holding block 82 has a hollow circular cylinder extension 85 provided for this purpose.
  • the opening in this extension serves as a receiving opening for the screw 88 and is adjacent at the same time the axis of rotation for the mandrel block 26 about the first axis 86.
  • the holding block 82 has two fork arms 84, at the free ends of which two aligned through-openings 83 are provided.
  • the holding block 82 can be fastened to the fastening block 6 in a pivotable manner via these through openings in 83 with the holding pin 81.
  • the fastening block 6 has two lateral recesses and a through opening 92 in them.
  • the two fork arms 84 of the holding block 82 can be pushed into or onto these recesses until the through openings 83 are aligned with the through opening 92, after which the transverse pin 81 be inserted.
  • the eyebolt 22 is pivotably articulated with the fastening pin 21 on the fastening block 6.
  • the locking pin 7 is also mounted in the recess 8 so as to be displaceable against the return of the spiral spring 13.
  • the locking pin 7 is caught by the transverse pin 20, which passes through the transverse hole 64, protrudes beyond it on both sides, and engages in the elongated guide hole 48 in the fastening block 6.
  • the locking pin 7 is accordingly only displaceable in the recess 8 within the limits specified by the elongated hole 48.
  • the locking pin 7 clamps the loop of the wrist strap with its tip, for this purpose a concave area 10 is also provided here, which delimits the area 15.
  • the unit thus formed from holding block 82, mandrel block 26 and fastening block 6 is held in the recess 4 in the handle head by the tensioning pin (eyebolt) 22 fastened via the fastening pin 21, which is tensioned from below via the cavity 5 with the spiral spring 23 and with the locking nut 24 is attached.
  • the release button 18 is also captured on this unit via the transverse pin 21.
  • the two free ends of the transverse pin protrude beyond the lateral surface of the fastening block 6 and engage in the two curved elongated holes 101 of the release button 18.
  • the release button 18 has a transverse through opening 100 and is mounted in the handle head so that it can be tilted about the axis of this transverse pin 11 via the transverse pin 11, which passes through the through opening 109 in the handle body. If the release button 18 is pressed down in the rear area, ie at the retaining pin 14, the cross pin 21 is displaced in the running direction due to the link 101 and thus the locking pin 7 is pushed further into the recess 8 against the force of the spring 13, and thus the Area 15 released. This is the manipulation that is carried out when the user properly uses the Wants to detach the wrist strap from the grip body.
  • the mandrel block is rotatably mounted about the axis 88 on the holding block 82, a V-shaped extension 39a on the holding block 82 engaging in a receiving pocket 94 in the mandrel block 26 here as well. If the mandrel block is rotated about the first axis of rotation, the extension 39a moves along the inclined flanks 95 and moves the fastening block 6 upwards against the return of the spring 23.
  • the fastening block 6 moves somewhat counterclockwise about the axis 81, so that the area 15 is opened somewhat, and the fastening block 6 shifts somewhat to the right.
  • the transverse pin 11 can be displaced in an elongated upwardly open recess 110 of the fastening block 6.
  • the release button 18 remains in its normal position. This now leads to the transverse pin 21 migrating upward in the curved link 101 and thus the transverse pin to the left and the locking pin 7 being pushed into the fastening block 6.
  • the fastening pin 7 follows the displacement of the fastening block 6 in the illustration in FIG Figure 5 g) not to the right and so the eyelet is released from the area 15.
  • the cover 102 is the cover 102.
  • the handle body has two opposed, transparent or even formed as a through opening areas 115 through which the spiral spring 23 is visible.
  • the cover 102 which can for example be made of transparent or translucent material and can be provided with a decoration entirely or in partial areas, can now be snapped onto the grip body from behind, the areas 115 being covered.
  • the cover 102 is designed to some extent in the form of a saddle, but it is also possible to provide two such covers individually for each side.
  • non-slip surface can be produced, for example, by a sprayed-on skin made of a softer plastic material or by a structured, roughened surface.
