Definitions

• the invention relates to a hand strap assembly for fixing a hand strap in a handle of a sports pole, such as a ski pole, a walking pole or a pole for roller- skating for example.
• a hand strap which has a joining element for joining the hand strap into the handle.
• the connecting part of the hand strap is fixed directly into the hand grip with some kind of a locking arrangement.
• a prior art assembly One problem with such a prior art assembly is that the strap needs to bend at the interface between the strap and the handle whenever the user's hand moves. This causes the strap to become worn at the point of the interface.
• Another problem with such an arrangement is that it is not very easy to release and insert the hand strap from/to the handle. Releasing the hand strap may be necessary, for example, in order to change the hand strap.
• Patent document US 6502862 discloses a hand strap assembly, wherein a loop element of a the hand strap is fixed to the handle of a pole using separate drawing elements. These drawing elements may have a bolt element at their end for the attachment of the hand strap to the handle. It is thus possible to insert and release the bolt element and the hand strap from the handle.

It is thus possible to insert and release the bolt element and the hand strap from the handle.
• Patent document CH 195360 discloses a partial solution to the problems discussed above. This document discloses an arrangement wherein a strap loop is fixed to the handle of a pole using a releasable ring attachment. The strap is tread through the attachment ring and the strap can thus turn at the ring. The ring may also turn at the attachment to the handle. The strap loop can be released from the handle by pulling the strap upwards and thus releasing the ring from the handle.
• the hand strap loop may easily be released unintentionally from the handle. This may happen if the user loosens the grip from the handle while pulling the pole forward. In this situation the attachment ring is pulled upwards and is released from the handle. The unintentional falling away of the pole this way may be very undesirable, especially in sports competitions.
• the users of the sports poles often like to have their grip at the upper end of the handle.
• the fixing ring may turn into wrong position under the user's hand. This may hurt the user's hand, or the ring may be in such a position where it can not bear the necessary forces.
• the objective of the invention is therefore to provide a hand strap assembly, which is easy, reliable, efficient and ergonomic to use.
• the object of the invention is achieved by providing a hand strap assembly in which there is a joining element between the hand strap and the handle, and wherein the joining element is connected to the handle with a joint allowing the joining element to turn during the use of the sports pole.
• the joining element has a quick release joint with the handle to allow easy releasing and changing of hand straps. It is also possible to provide an easy adjustment between the strap and the joining element.
• An assembly according to the invention for fixing a hand strap in the handle of a sports pole comprising a joining element which is connected to the handle and to at least one fixing strap of the hand strap, is characterized in that the joining element is fitted to the handle by means of a joint allowing the joining element to turn, and the joining element has at a distance from the joint an opening through which a fixing strap of the hand strap is threaded in order to fix the fixing strap to the joining element, whereby the turning of the joining element allows a movement of the hand strap relative to the handle during the use of the sports pole.
• the distance from the interface between a fixing strap and the joining element to the closest point of the handle surface or extension thereof is smaller than the distance from the joint between the joining element and the handle to said same point.
• the present invention offers several advantages when compared to the prior art hand strap assemblies.
• the straps do not need to make sharp bending when the position of the user's grip is changed e.g. in the direction of the handle.
• the user can also pull the pole while moving the hand forward without any risk of the pole getting loosened from the strap/joint.
• the joining element is able to turn even under the hand of the user, and the joining element does not get into any positions which could be harmful to the user's hand, or positions where an exerted force of training might damage the parts, or positions where a proper usage of the pole is not possible.
• One further advantage of the assembly according to the invention is that the fixing strap running from the hand strap can be locked into different positions in regards to the joining element in the handle, whereby it is possible to adjust the distance between the hand strap and the handle.
• the fixing strap runs horizontally through an opening of the joining element retaining its width, whereat by stretching strain it need not bend/twist even if the handhold on the pole would change.
• the joining element which is twistingly fixed in the handle secures that at skiing the strap does not get into bending when the handhold changes.
• the strap can be easily locked to the joining element opening.
• locking means include e.g. a wedge, a buckle which can be integrated to the joining element, stickers at the surface of the straps.
• the adjustment can be made easily without tools.
• the fixing strap can also be sewed or otherwise permanently locked into a determined length.
• the joining element can also be easily constructed removable by quick release locking, whereby the hand strap is easily changed for instance into a pole of different length.
• sports pole means in this patent application e.g. ski poles, walking poles or roller-skating poles.
• sports pole is not limited here to only certain use but it includes any poles used for human activities in leisure time, professional sports, etc.
• sticker means in this patent application material, which has a surface that sticks to a surface of other similar material, such as velcro, thus providing repeated mutual attachment of two strap parts.
• surface extension relates in this patent application to a handle which has a recess for a joining element.
• the surface extension means the area where the surface of the handle would be if the recess would not exist.

• FIG 1a shows an exemplary hand strap assembly 1 of a sports pole according to the invention.
• the strap has a wrist part comprising a self adhesive strap portion and a buckle for adjustment of the wrist part to match the measures of the user's hand.
• the tightening strap 8 of the wrist part is threaded through the buckle and turned back. Thanks to its self-adhesive sticker surface, part 8 gets re-fixed turned from buckle to its own surface that remained on the other side of buckle.
• Figure 1 shows that also fixing strap 3 gets from its other end fixed below self adhesive portion 8.
• the length of the attachment strap 3 can be adjusted by selecting, on which spot the attachment strap is located below the part 8, and be locked there.
• the other end of the attachment strap 3 can be permanently sewed in the hand strap.
• the attachment strap 3 circulates through a joining element 4 in the handle portion 10, whereby the attachment between the hand strap and the handle is achieved.
• the strap 3 runs through an opening 9 of the joining element 4.
• the attachment strap 3 is thus bended only perpendicular to width direction, and thus only in the direction recommended for straps. Therefore no harmful stretching strain arises in the attachment strap 3.
• the joining element 4 can be attached to the handle 10 by means of a joint 6. There is arranged a formation of a hollow in the handle 10 for the joining element as a turning space that it needs.
• the joining element is mainly inside the handle and there able to turn at least 20°, or even 30 ° . When the user's hand is moving in changing the grip at the handle, the joining element 4 turns accordingly.
• the attachment strap therefore does not get into bending even if the hand makes grip changes.
• joint pin 6 for example.
• the joint does not allow a quick release of the joining element 4 from the handle.
• the hand strap can still be removable, since the free-released end of attachment strap 3 can be thread trough opening 9 of the joining element 4.
• a quick-release locking of the joint pin 6 in the articulation may be implemented e.g. so that on pushing the joint pin 6 the joining element 4 releases the locking of pin 6 and the hand strap 1 is then removable.
• Figure 1 b shows an exemplary joining element 4 which can be used in a hand strap assembly according to the invention.
• a hole 7 for instance for locking by means of joint pin 6 and in the other end an opening 9, from which attachment strap 3 is thread through.
• Strap 3 is locked in opening 9 e.g. by means of a wedge 5, buckle or other manner known per se.
• Figure 1c shows the upper part of an exemplary handle according to the invention.
• the handle 10 is shown partly cut, whereby the formation of the hollow formation for joining element 4 is illustrated as well as the space for turning of the joining element, angle ⁇ .
• one portion 2 of the handle 10 there is, for instance, cork as coating.
• FIG. 2a illustrates side view of another exemplary hand strap assembly of the invention.
• the handle 20 has a space for a joining element 24, and the joining element is connected to the handle by means of a joint.
• the joint can be released by pressing a button 26.
• the joining element also has a vertical hole 29 for the attachment of the fixing strap.
• FIG. 2b illustrates an exploded view of the assembly according to Figure 2a.
• the handle 20 has a space 268 for a joining element 24 and a support part 264.
• the handle also has a hole 261 for a press button 260.
• the press button 260 is installed from the inside of the handle into the hole 261.
• the button 260 has a shoulder, which prevents the button to come through the hole.
• the support part 264 is installed from above the handle into the space.
• the hole 265 of the support part will be located concentric with the hole 261 of the handle and with the button 260.
• the joining element is installed into the space 268 between the support part 264 and another side wall of the handle.
• the joining element 24 has a projecting part 27, which snaps into the hole 265 of the supporting part.
• the projecting part 27 of the joining element 24 can rotate within the hole 265 of the support part 264. Due to this articulated joint the joining element 24 can turn within the space 268. When button 260 is pressed, the button pushes the projecting part 27 out of the hole 265. Thus the joining element can be removed from the handle.
• the hand strap is fixed to the hole 29 of the joining element.
• the force of the hand strap is led via the joining element and projecting part 27 to the support part 264 and further to the handle 20. Since there may be large forces applied, it is preferable to produce the joining element and the support part of a strong material.
• the support element and/or the joining element may be made of different, stronger and more durable material than the main part of the handle 20.
• the support element and/or the joining element can be e.g. different type of plastics than the main part of the handle.
• Figure 2c illustrates a joining element 24 of the assembly according to Figure 2a.
• the Figure shows the projecting part 27 and the opening 29.
• In the opening there is an integrated wedge in order to slightly tighten the strap into the opening and thus prevent sliding of the fixing strap.
• Figure 2d illustrates one alternative for attaching the fixing strap to the joining element 24 of an assembly of Figure 2a.
• the main strap which is led between the thumb and the forefinger is marked 281.
• a separate fixing strap 231 is attached to the main strap e.g. by sewing.
• the fixing strap 231 is thread through the opening 29 of the joining element.
• FIG. 3a illustrates a further exemplary embodiment according to the present invention.
• the handle 30 has a recess 368 for a joining element 34.
• the joining element has an articulated joint at both sides on the handle.
• the joining element has projecting parts 37 at its sides, and the projecting parts snap directly into circular holes at the sides of the handle 30.
• the projecting parts can rotate within the circular holes, and thus the joining element can turn around the middle axis of the holes.
• the joining element can be removed by pressing the projecting parts 37 at both sides.
• the projecting parts are thus turned out of the circular holes, and the joining element can be released by pulling it out from the handle.
• the joining element 34 of Figure 3a has means for fixing two fixing straps to the joining element.
• a first, lower fixing strap can be led through openings 391 and 393.
• a second, upper fixing strap can be led through openings 392 and 393.
• Figure 3b illustrates a joining element 34 of the assembly of Figure 3a.
• the Figure 3b shows the two projecting parts 371 and 372 of the joining element, which provide the articulating joint with the handle.
• the Figure 3b also shows the upper opening 392 and the middle opening 393 for fixing straps.
• Figure 3c illustrates one alternative for attaching the fixing strap to the joining element 34 of an assembly of Figure 3a.
• the main strap parts are led directly to the joining element as fixing straps.
• the lower strap 281 is connected at a fixed length to the joining element.
• the upper strap 396 is leas through openings 393, around a shaft 395 and through openings 392 and 393. This way the joining part functions as a buckle and the upper fixing strap can be adjusted and locked to a desired length.
• the embodiments described above included arrangements where the joining element is mostly located within the handle. Although this is a preferable arrangement, it is also possible to locate e.g. the sides of the joining element outside the handle. For example, by producing the joining element in Figure 3a wider, it would be possible to have the sides at the outer surface of the handle.
• the articulating joints could be made e.g. with a shaft without a quick release construction. Using such an arrangement it would be possible to make the recess within the handle much smaller. With a smaller recess the handle might also be stronger.
• the fixing strap may be directly led from the wrist part of the hand strap, or the fixing strap may be a separate strap which is connected to a strap part being led between the thumb and forefinger of a user's hand.
• the fixing strap can be an integral part of the hand strap, and the hand strap, including the fixing strap(s) can be made of a single fabric.
• the described embodiments have a joining element including a hole for attaching the fixing strap, also other means for attaching the strap to the joining element can be designed.
• the advantageous applications of the present invention include walking poles, ski poles and roller-skating poles, but the hand strap assemblies according to the scope of the invention include applications for any poles used for human activities.
