KÄSIHIHNASOVITELMA

The invention relates to a handle device, such as a tool or a hand strap arrangement placed on a ski and walking handle. The hand strap assembly consists of at least one strap attachment member and a strap arrangement extending from the attachment member and adapted to pass around the hand.

The utility model FI-4881 incorporates a strap attached to a tool arm which improves the hand grip efficiency when using movable tools. The strap attachment points are on the handle / handle of the hand tool outside the edge line of the hand grip.

The disadvantage of such belt tensioning is that the tool shaft has to be modified even for holes to fasten the belt. These holes or similar changes in the shaft will weaken the strength of the shaft. The fastenings must also be sturdy, as the ends of the strap are fastened at each point to the shaft.

Knobs and straps for ski poles are known for example. EP 1105194, DE DE 4029688 A1 and US 5,248,163. Each of these publications discloses, as a handle part, a handle sleeve, e.g., attached to the end of a rod tube by means of a hot glue, which is pushed to the end of the rod tube as far as it can go. The handle, the sleeve has fastening means for a strap, both ends of which are attached to the handle. Rods * *, '»are manufactured in various diameters and circular cross sections as well as • 1 ·' 25 oval. The handle sleeves must be fitted with the inside diameter and the shape of the inner hole for the pipe in question.

. * -, This type of handle is difficult to remove from the rod tube and other tool arms because the · · ', hot-glue joint requires heating before attempting to remove. The wax, 30 wax sleeves must be relatively accurate with respect to the inside of the shaft or tube for its • · * f * * · installation. It is impossible to mount a circular sleeve handle on eg an oval tube.

'·' · 'Further, such a handle can only be mounted in one axial position on the shaft or rod tube. In addition, in most cases of ski poles, the strap starts at a bad position on the handle or even at the end of the shaft so that it is not preferably positioned with respect to the movement between the hand and the handle and the transmission. The known solutions have had to be followed by a strap attachment to the ends of the strap and in most cases this strap had to be combined with a strap length adjustment.

Further, a solution is known from U.S. Patent No. 3,995,872, in which a ski bar strap is attached to an open sleeve-like mounting member body. The attachment body is located under the handle of the sauerkraut. The belt does not wrap around the rod tube and thus allows the belt to be released in the event of an overload.

A solution is known from US Patent 6,135,902, wherein the strap attachment member is an open sleeve which engages around the handle portion. However, the strap does not rotate around the rod tube, which also causes the belt to loosen under certain stress.

It is an object of the invention to provide a new hand strap assembly which is easy to attach to a tool arm or a ski tube for ski and walking poles and which is easy to disassemble as well as to be moved on a shaft or tube. The hand strap assembly according to the invention is characterized in that at least one part of the strap which is part of the strap stiffening is arranged to extend around the fastening body of the arm.

20; * The advantage of the inventive hand strap assembly is that the new fastener type does not require: a precise fit between the fastener and the arm. The shaft or tube may even be slightly oval in cross-section and still be mainly for a circular shaft according to the invention; . this hand strap arrangement fits over it. The diameter difference may also be at least ± 1 mm between the fastening member to be mounted and the tube, and still the attachment member can be fitted reliably on the shaft. The strap around the user's hand wraps intact around the shaft and comes from the strap guides fitted in the attachment member and are oriented in the most favorable direction. · ·. out of the openings towards the user. As the belt passes around the arm, it tightens the fastening member *, in the operating position and also in various ways of locking the belt, the belt is also available to continuously tighten the fastening member against the handle.

> * '·>>' For skiing and walking stick applications, the attachment member is easily adjustable to different heights, and • the attachment member can be followed by a separate lock to ensure the body's resistance to high axial forces. Preferably, the mounting member is further shaped as a handle.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a hand strap assembly attached to a tool or ski rod arm.

Figure 2 shows another hand strap assembly attached to the tool arm.

Figure 3 shows a third arm strap assembly attached to the tool arm.

Fig. 1 shows a hand strap assembly according to the invention attached to a tool such as a hammer, ax, hydrant arm 1 or e.g. ski ski tube 1 comprising an open sleeve-like fastening member body 2 extending substantially over the largest diameter 15 of the arm 1. On the opposite side of the arm 1 there is a second body part 2 'which also extends beyond the largest diameter of the arm 1 for better grip. The hand strap 3 is arranged to rotate about the arm 1 and also around the part 2 'and is guided inside the body 2 so that it can come out of the oblique openings of the part 2 on both sides of the arm. The strap 3 binds the part 2 'to the shaft. Also, the portion 2 'is dimensioned such that it is itself tensioned around the shaft and does not bend away as it extends over half a revolution around the shaft. Also, part 2 is also tensioned around arm 1 and the attachment member as a whole remains on arm. Tensioning of the strap during use and gripping only increases the stability of the parts 2 and 2 'on the shaft. The parts 2,2 'are preferably plastic. Their inner surface or pieces may be made entirely of rubber / plastic compound, whereby the friction on the inner surface is • »·. ·· ·. 25 roin becomes great.

Figure 4 shows a ski or walking stick tube 1 to which a fastening member 2 is attached. The attachment part 2 includes an extension 11 which plugs the end of the tube 1 and at the same time prevents the attachment part 2 from sliding down the rod tube 1 during use. For a better grip, this also includes a second body portion 2 ', around which, or outside, if there is sufficient thickness in the part 2', the belt 3 rotates the shaft 1 through a channel formed in the part 2 '. . The strap 3 may be imaged on the inside of the part 2 against the arm 1 in a confined space so that by tensioning the strap coming from the opening vigorously, the parts 2 and 2 'remain under tension against the arm 1. The strap may also be designed so that it slides well outwardly in the outlet, but in the other direction, inwardly, it tends to lock into or out of the opening due to wedge-shaped, barbed or constricted structure.

From the attachment member 2, an auxiliary belt 7 is provided which has an outlet in the attachment member body 2 and to lock the end of the strap 7 to the attachment member body 2, a recess 12 is formed inside the attachment member 20 body 2 so as to accommodate The strap 7 may also be a two-piece or integral loop, whereby the two strap sections must: engage the body 2. In this case, the strap 7 may also wrap around the rod tube 1 and come out of the body through two recesses or even openings with the strap 3. Also this hih-! '. The belt then supports the attachment of the part 2 to the tube 1 and the pivoting pivoting pins via the thumb strap.

· * In addition to the parts being locked. The maximum load of the ski and walking stick attachment member is downwards, so that the locking according to Fig. 5 strengthens the attachment member of the attachment member 5 115452 precisely against this stress. The thumb grip area is represented by line P and the palm grip area by line K. The adjustment distance is S.

The locking arm 9 can also be partially or completely replaced by an adjustable strap, one end of which is fixedly attached to the part 11 or the body part 2 and tears at one end to the projection (pin, pin) or locking screw of these parts.

In these solutions, the strap 3 enters the palm and thumb region in the most preferred direction 10 and is positioned at the correct position on the arm in front of or above the thumb grip. The palm rest can be freely detached from the handle formed by the attachment body, and yet the strap 3 ensures that the tool or rod remains in the correct position between the open palm and thumb. In one embodiment of the arrangement, the belt outlets could also be located such that the attachment of the strap to the device strikes between the front edge of the palm and the thumb.

FIG. The various selected clamping lengths of the belt portion 7 '20 allow the clamping member body to be locked in the desired positions.

Parts 2, 2 ', 5 and 6 are made of a somewhat flexible material such that, ·; are smaller in internal space than the intended shaft or tube on which they are tensioned. Various friction enhancing coatings or means may be placed on or between the hand strap assembly and the arm surfaces.
