Description

The invention relates to walking sticks for walking or running, for sports on nature trails, mountain or plain, such as trail, Nordic walking, hiking, "trekking" or the mountain race. The invention can also be applied to ski poles, ski touring or cross-country skiing.

The use of poles makes it possible, on the one hand, to help oneself with one's arms to relieve the uphill legs by transferring part of the load to the upper body and, on the other hand, to secure the supports by increasing their number, the improvement of the grip on slippery grounds (wet slopes, passage of streams, waterfalls ...) or poorly stabilized (gravel, scree, mud).

The technique of walking with poles is close to that of cross-country skiing, either in simultaneous thrust by planting the two sticks together every 2 to 3 steps or one baton after another at each step. The sticks can be kept by hand for the entire walk or race. The handles of some walking or running sticks also have a strap, allowing the user to release the handle of these without losing or dropping them.

The sticks can be telescopic to be stored or to adapt the length of the stick to the slope of the ground. However, this means may prove too long to implement during a race, especially on a rough course where their implementation can be frequent.

Another disadvantage of these sticks is the risk of injuries that can occur by wrist restraint in the wrist strap. Indeed, in the event of a fall or blockage of the tip of the stick, the user's hand may become stuck in the wrist strap, risking injury to the user, dislocation of the shoulder or wrist injury.

In addition, the user must strongly tighten the handle of the stick to help it without the hand skidding on the handle. This high pressure is a source of tension in the forearms of the user. Using the wrist straps to push without tightening the handle can be dangerous because of the risk of injury mentioned above.

One of the aims of the present invention is to propose a support stick intended for walking or running which can adapt the distance between the user's hand and the ground to the slope of the ground and the size of the ground. user. Another object of the present invention is a support stick intended for walking or running facilitating the effort of the user, can also be dropped without risk of being lost, while limiting the risk of injury by the strap.

For this purpose, the subject of the invention is a support stick intended for walking, running or skiing, comprising a handle, characterized in that it comprises a removable handle support projecting from the handle to forming a support under the portion of the grip portion of said handle to be grasped by the user, said support support having height adjustment means for positioning the removable handle support at different longitudinal positions of the handle.

To this end, the invention also relates to a support stick for walking, running or skiing, comprising a handle, characterized in that it comprises a removable handle support protruding from the handle to form an anchor piece of a strap placed above the portion of the grip portion of said handle to be grasped by the user, said support support having height adjustment means for positioning the support removable handle at different longitudinal positions of the handle.

Thus, during a walk or a race with poles, the length of the stick between the gripping part and the ground can be adapted to the slope of the ground. In addition, the user's hand can be supported on the removable handle support to propel itself and facilitate its progression without particular effort to hold the handle tight, avoiding the tensions that can be generated in the forearms.

The document of the prior art DE 26 32 201 describes a stick having a removable handle sliding on the upper part of the stick. This handle comprises an upper portion on which is attached a strap and a cylindrical main body which ensures in all positions of the handle gripping area of the stick by the user. Such a system has many disadvantages. In addition to the heaviness and complexity of the locking device of the handle in position, it is in particular reliability issues that pose a significant problem to users. Indeed, a malfunction or the breakage of the lever of the locking device renders the latter inoperative and therefore unusable stick, because the handle can not be attached to the stick.

Unlike the stick of the prior art, the invention proposes an advantageous solution insofar as the gripping zone of the stick by the user does not move with the removable support support, but it is the support removable support that moves along an area that is the potential gripping area.

The stick of the invention is characterized in particular by the fact that means for stopping the longitudinal movement of the hand along the gripping portion are provided. Indeed, since the gripping portion is long, in any case longer than the width of a hand, the user can grasp the stick in different positions of the gripping portion. In the remainder of this document, reference will be made to the portion of the grip portion intended to be grasped by the user's hand, the zone of the handle grasped by the hand at a given moment. The stop means prevent inadvertent slipping of the hand, for example due to too weak a capture.

According to a first embodiment of the invention, the means for stopping the longitudinal movement of the hand, along the gripping portion of the stick, comprise a support plate placed under the portion of the gripping portion of the handle which is intended to be entered by the user.

According to the first exemplary embodiment, said removable or sliding handle support cooperates by clipping with said handle to position the removable handle support at different longitudinal positions of the handle.

It can further be envisaged that said removable handle support cooperates with a profile of said gripping portion of said handle to position the removable handle holder at different longitudinal positions of the handle.

For example, said gripping portion has a succession of reliefs and recesses distributed along said handle, and said removable handle support has a fork configured to cooperate with the reliefs and recesses of the gripping portion of the handle by clipping the support removable handle at different longitudinal positions of the handle.

The successive reliefs and recesses may be regularly spaced at least two centimeters along said handle. The steps of movement of the height adjustment means then allow a setting both fast and accurate.

It is thus possible to adjust in a simple manner the position of the removable handle support on the handle by clipping the fork to a hollow having a height adapted to the will of the user. The handle formed by the profiled portion of the handle and the removable handle support can then be adjusted in height to adapt the position of the hand on the support stick at the slope of the ground.

The gripping portion of the handle may comprise an elastic material. Thus, the reliefs and hollows can be elastically deformed to clip the fork to the handle.

The fork has for example a narrowing to clipper by pinching the hollow of the handle. The ends of the narrowing are respectively provided with protruding bulges perpendicularly of the removable handle holder. The bulges are therefore projected against the reliefs, located on either side of the hollow cooperating with the removable handle support, which allows in particular to longitudinally retain the support to the handle in the position of use.

A circular groove may be provided in the recesses of the handle to cooperate with a radial projection of the fork of the removable handle holder. The insertion of the radial projection in the circular groove guides and participates in the maintenance by clipping of the fork to the handle.

The reliefs may have a shape at least partially spherical to facilitate and improve the grip of the handle by the user, the fingers of the hand can naturally be inserted between the reliefs of the handle at any height position of the handle support removable.

The removable handle support may have a front portion shaped to match the shapes of the reliefs reinforcing the reliability of the clipping and ensuring good stability of the removable handle support once it attached to the handle.

The removable handle holder may have retaining means cooperating with the handle to retain the removable handle holder when the fork is unclipped. This avoids losing the removable handle support when not clipped to the handle.

For example, two communicating lights are provided in said removable handle holder, the contours of a first lumen narrowing to form a fork cooperating with the reliefs and recesses of the handle for clipping the removable handle holder in a use position and the contours of a second light cooperating with the reliefs of the handle to retain the removable handle holder in a setting position and through which the reliefs of the handle can pass.

The shape of the outline of the second light can substantially match the widest periphery of the relief in the plane normal to the handle. Thus, the retention of the removable handle holder on the handle is improved since additional pressure is then required to move the removable handle holder through the reliefs along the handle.

The gripping portion of the handle has for example a length greater than 35 centimeters. To properly support the edge of the hand of the user, said removable handle holder has for example a protruding length of between 35 and 70 millimeters, preferably between 40 and 60 millimeters.

The support rod comprises a rod extending the handle which may have a succession of at least two reliefs and a hollow interposed between the two reliefs at a position of equilibrium to cooperate with the fork of the removable handle holder. Thus, the user can, if he wishes, continue his race without the use of poles but by wearing them horizontally. The removable handle holder being clipped in the vicinity of the center of gravity, the weight of the support stick is balanced on both sides of the holding position so that its porting is facilitated.

The removable handle support may comprise a retaining buttress, a first end of which is connected to a plate of the removable handle support projecting from the handle and a second end of which is shaped to cooperate with the handle. The second end of the retaining buttress may comprise two teeth cooperating with a recess and a relief of the handle. Thus, the load is better distributed on the strut formed by the retaining buttress.

The support stick may comprise an attachment band connected to one end of a plate of the removable handle support projecting from the handle, an inner surface of said fastening strip having attachment means intended to cooperate with additional hooking means carried by a clothing element of the hand of the user.

The fastener strip is then loosely connected to the movable handle holder with the clothing element of the hand and is not stressed during the effort. The attachment means therefore remain in place without requiring a large resistance force against the recess. The user's hand remains tied to the support stick by the fastening band without being belted by it as it would have been in a hand strap.

The support stick, then retained to the user can be released temporarily by the latter, for example to relieve the runner on small portions of the course where their use would no longer be justified or to free the hands to destine them to other uses. The sticks can remain hanged to the item of clothing worn by the user without it having any special effort to do to hold them and without having to put them on the ground. And, when the use of sticks proves again necessary, the user can quickly resume the sleeves of these.

The strap does not interfere with the wrist of the user, it does not remain stuck in case of falling or blocking the stick. In addition, the attachment means do not require a large resistance force to the recess, they can be chosen so as to be easily detachable and yield quickly under a greater effort, such as in case of a fall, thus avoiding the hand to remain a prisoner.

According to a first exemplary embodiment, said attachment means comprise ribbons provided with loops or hooks to form a VELCRO type connection with complementary attachment means.

According to a second exemplary embodiment, said attachment means and said complementary attachment means comprise respectively at least one magnetic metal element, said magnetized metal elements cooperating with each other.

According to a second and a third embodiment of the invention, the means for stopping the longitudinal movement of the hand along the gripping portion of the stick comprise an anchor piece of a strap, said piece being placed at above the portion of the gripping portion that is entered by the user.

Said fastening strip is for example connected to the end of the plate of the removable handle support by a strap passing through a bar resulting from the residue of material between two windows formed in the end of the tray of the removable handle holder.

The window may have an arcuate shape allowing lateral sliding of the adjustment strap. This facilitates the pivoting of the fastening strip relative to the removable handle holder, which increases the freedom of pivoting of the hand around the handle.

In these figures, the identical elements bear the same reference numbers. In the rest of the text, the "bottom" side corresponds to the side of the tip of the support stick as opposed to the "up" side corresponding to the side of the handle of the support stick.

The figure 1 represents a user 1 gripping the handle 2 of a support stick 3, intended for walking or running.

Walking sticks or running sticks are usually used in pairs, for sports on nature trails, mountain or plain, such as trail, Nordic walking, hiking, trekking or mountain running. The use of poles allows, on the one hand, to help his arms to relieve the legs uphill by transferring part of the load on the upper body and secondly, to secure the supports. The sticks can be straight (as represented on the figure 1 ), telescopic or foldable to be folded and stored.

As can be seen on the figure 2 , the support stick 3 comprises, in a conventional manner, a longitudinal rod 4 ending in a point at the opposite end of the handle 2. The tip may comprise a tip or washers, large for snowy or small terrain for " dry ".

The handle 2 has a gripping portion 100 which may comprise a succession of reliefs 6 and recesses 7 distributed along the handle 2.

The support stick comprises a removable handle support projecting from the handle 2 to form a support under the portion of the handle portion of the handle 2 to be grasped by the user. In addition, the support stick has height adjustment means for positioning the removable (or displaceable) handle support at different longitudinal positions of the grip portion 100 of the handle 2.

In the stick of the invention, the gripping portion 100 extends over a length greater than the width of the user's hand. The latter may choose to grab the stick at any position on the stick and it can move the removable support at leisure, so that it forms a support under the portion of the gripping portion 100 of the handle 2 which is entered by the user or as we shall see further, an anchor piece of the strap, above this gripping portion.

Thus, during a walk or a race with poles, the length of the support stick 3 between the gripping portion and the ground can be adapted to the slope of the ground. In addition, the hand of the user 1 can be supported on the removable handle support to propel and facilitate its progression without particular effort to hold the handle tight, avoiding the tensions that can be generated in the forearms.

According to the exemplary embodiment shown on Figures 1 to 12 , the removable handle support cooperates by clipping with the handle 2 to position the removable handle holder at different longitudinal positions of the handle 2. Also, in this example, the removable handle support cooperates with a profile of the gripping portion of the handle 2 to position the removable handle holder at different longitudinal positions of the handle 2.

According to a first variant represented on Figures 1 to 8 , the handle support 8a ( Figure 3a, 3b ) has a plate 9 protruding from the handle 2 substantially perpendicularly ( figure 1 ), to form a support transverse to the edge of the hand of the user 1. The plate 9 of the removable handle holder 8a may have a generally substantially concave shape to improve the holding of the hand. To properly support the edge of the hand of the user, the plate 9 of the removable handle holder 8a has for example a length of between 35 and 70 millimeters, preferably between 40 and 60 millimeters is shown the hand of the user 1 open on the handle 2, resting on the plate 9 of the removable handle holder 8a in figure 4 .

Better visible in Figure 3a or 3b , the removable handle support 8a has a fork 10 configured to cooperate with the reliefs 6 and the recesses 7 of the gripping portion of the handle 2 for clipping the removable handle holder 8a to different longitudinal positions of the handle 2. For this purpose, the profiled gripping portion of the handle 2 is provided longer than a conventional handle. For example, the gripping portion of the handle 2 has a length greater than 35 centimeters, preferably less than 55 centimeters for a total length of the support stick 3 (handle 2 and rod 4) of between 1 and 1.3 meters.

The removable handle holder 8a is for example of rigid material, such as plastic and the gripping portion of the handle 2 is of elastic material, for example rubber. Thus, the reliefs 6 and the recesses 7 may be elastically deformed to clip the fork 10 to the handle 2.

One can then simply adjust the position of the removable handle holder 8a on the handle 2 by clipping the fork 10 to a recess 7 having a height adapted to the will of the user. The handle formed by the profiled gripping portion of the handle 2 and the support of removable handle 8a, can then be adjusted in height to adapt the position of the hand on the support stick 3 at the slope of the ground.

For example, a regular succession of reliefs 6 and annular recesses 7 is provided to optimize the positions of height adjustments. For example, the reliefs 6 and the successive recesses 7 are regularly spaced at least two centimeters along the handle 2. Thus, the height adjustment means are able to position the removable handle holder 8a with displacement steps allowing a setting that is both fast and accurate.

The reliefs 6 advantageously have an at least partially spherical shape to facilitate and improve the grip of the handle 2 by the user, the fingers of the hand can naturally be inserted between the reliefs 6 of the handle 2 at any position in height of the removable handle holder 8a.

As distinguished on the example of the figure 3a , the fork 10 has a narrowing for clipping by pinching the recess 7 of the handle 2. The ends of the narrowing are respectively provided bulges 11a, 11b protruding perpendicularly from the removable handle holder 8a, on either side of the plate 9. bulges 11a, 11b are therefore projecting against the reliefs 6, located on either side of the hollow 7 cooperating with the removable handle holder 8a.

In the case of elastic reliefs 6, the bulges 11a, 11b deform the reliefs 6 during the coupling of the fork 10 to the handle 2 and then retain the removable handle holder 8a once the fork 10 coupled to the recess 7 of the handle 2 , the reliefs 6 then having resumed their original form. The bulges 11a, 11b have for example the shape of ramps culminating upstream of the narrowing of the fork 10, which facilitates the elastic deformation of the reliefs 6.

The removable handle holder 8a may also have a front portion 11c shaped to match the shapes of the reliefs 6. The front portion 11c has for example protruding bulges perpendicularly of the removable handle holder 8a, on either side of the plate 9 , marrying the partially spherical shapes of the adjacent reliefs 6. The bulges at the ends of the fork 11a, 11b and in the front portion 11c then have a wavelet shape on either side of the plate 9, improving the longitudinal retention of the removable handle holder 8a. The reliability of the clipping of the fork 10 is then reinforced, ensuring good stability of the removable handle holder 8a once it is attached to the handle 2.

According to an exemplary embodiment visible on the figure 6 , a circular groove 12 is formed in each recess 7 of the handle 2 between two successive reliefs 6 to cooperate with a radial projection 13 of the fork 10 of the removable handle holder 8a ( figure 3a ). The radial projection 13 is formed in the opening of the fork 10 of the removable handle holder 8a. The circular groove 12 is not felt by the fingers of the user resting on the spherical portions of the reliefs 6. Thus, the fork 10 of the removable handle holder 8a substantially deforms the reliefs 6 to fit into the throat circular 12 of the recesses 7 of the handle 2. The insertion of the protrusion radial 13 in the circular groove 12 guides and participates in maintaining by clipping of the fork 10 to the handle 2.

It is also possible that the removable handle support 8a has retaining means cooperating with the handle 2 to retain the removable handle holder 8a in a setting position when the fork 10 is declipped. The retaining means are then active and hold the removable handle holder 8a to the handle 2, when the fork 10 does not cooperate with the reliefs 6 and the recesses 7 of the handle 2. The removable handle holder 8a, however, remains free to pass them. reliefs 6 of the handle 2. This avoids losing the removable handle holder 8a when it is not clipped to the handle 2.

For example, and as depicted on the figure 3a , the removable handle support 8a has two communicating lights 14a, 14b formed in the plate 9.

A first light 14a has tapered contours to form a fork cooperating with the reliefs 6 and the recesses 7 of the handle 2 to clipper the removable handle holder 8a in a position of use. The first light 14a for this purpose has an area greater than the diameter of the annular recesses 7 of the handle 2 and less than the width of the reliefs 6 of the handle 2. The radial projection 13 is formed in the contour of the opening of the fork 10.

The contours of a second light 14b cooperate with the reliefs 6 of the handle 2 to retain the removable handle holder 8a in a setting position and through which the reliefs 6 of the handle 2 can pass. For this, the second light 14b has an area greater than the reliefs 6 of the handle. The area of the second light 14b is therefore greater than the area of the first light 14a. The elasticity of the reliefs 6 allows to unclip them from the first light 14a and move them through the communicating portion to the second light 14b. The removable handle holder 8a is thus retained at the handle 2 by the contours of the lights 14a, 14b of the removable handle holder 8a in the adjustment position.

The shape of the contour of the second light 14b can substantially match the widest periphery of the reliefs 6 in the plane normal to the handle 2. Thus, it improves the retention of the removable handle holder 8a since additional pressure is then required to deform the reliefs 6 and move the removable handle support 8a through the reliefs 6, along the handle 2.

The two communicating lights 14a, 14b have for example an eight-shape.

Thus, in a first "high" position of use of the support stick 3 ( figure 5 ), the radial projection 13 of the first lumen 14a cooperates with the circular groove 12 of the fourth hollow 7 of the handle 2 to clip the removable handle holder 8a. The center of the first lumen 14a is substantially oriented with the longitudinal axis of the support stick. In use, the hand of the user 1 squeezes the handle 2 and leans on the removable handle holder 8a, the fingers of the hand being interposed in the recesses 7 of the handle 2 located on the upper side to the fourth hollow.

Then, if the slope of the course requires to reduce the length of the support stick, for example uphill, the user unclips the fork 10 of the hollow 7 of the handle 2 by elastic deformation. For that, it pushes the handle 2 towards the second light 14b until aligning substantially the longitudinal axis of the stick with the center of the second light 14b (see the arrow D1 on the figure 6 ). The removable handle holder 8a is then retained in the handle 2 by the second light 14b in an intermediate adjustment position while being free to pass the reliefs 6 of the handle 2 to a second position of use (see arrow D2 on the figure 6 ).

When the position of the removable handle support 8a on the handle 2 is satisfactory for the user, the latter clips the radial projection 13 of the removable handle holder 8a in the circular groove 12 of the new hollow 7 of the handle 2. Thus, in a second "low" position of use of the support stick 3 ( figure 7 ), the first light 14a cooperates with the second recess 7 of the handle 2. The fingers of the hand are now inserted in the recesses 7 of the handle 2 situated on the upper side of the second recess 7.

Moreover, and better visible on figures 1 and 3a , the removable handle support 8a may comprise a fastening strip 15 connected to one end of the plate 9. The fastening strip 15 has an inner surface having attachment means intended to cooperate with complementary fastening means carried on the outer surface of a skating element 17 of the hand of the user 1.

Although on the figures 1 and 4 , the clothing element 17 is represented by a mitten, the clothing element 17 may be constituted by any other means allowing to be held in the hand of the user 1, such as a glove or a headband elastic around the back and the palm of the hand. In addition, gripping and / or antiperspirant fabric pieces 18 may be sewn into the inner surface and / or between the thumb and forefinger of the garment element 17, to enhance the comfort of the user 1 (see figures 4 and 8 ).

The fastening strip 15 is then loosely connected to the removable handle support 8a to the clothing element 17 of the hand and is not necessarily biased during the effort. The attachment means therefore remain in place without requiring a large resistance force against the recess. The hand of the user 1 remains linked to the support stick 3 by the fastening band 15 without being belted by it as it would have been in a hand strap.

The support stick 3, then retained by the user 1 may be temporarily released by the latter for example to relieve the runner on small portions of the course where their use would no longer be justified or to free the hands to destine to other uses. The support sticks 3 can thus remain hanging from the clothing element 17 worn by the user 1 without having any particular effort to do to hold them and without having to put them on the ground ( see figure 8 ). And, when the use of the sticks is again necessary, the user 1 can quickly resume the sleeves 2 thereof.

The fastening strip 15 does not interfere with the wrist of the user 1, it does not remain stuck in case of fall or blocking of the support stick 3. In addition, the attachment means do not require a great resistance force against the recess, they can be chosen so as to be easily detachable and give way quickly under a greater effort, such as in case of a fall, thus avoiding the hand to remain trapped.

According to a first example shown on the figure 3a , the attachment means 16a and the complementary attachment means 16b comprise ribbons respectively provided with loops and hooks, so as to form, in a manner known per se, a VELCRO (registered trademark) type connection.

According to a second example shown on the figure 3b the attachment means and the complementary attachment means respectively comprise two magnetized metal elements which cooperate with each other in pairs. Two first magnetized metal members 16c are attached to the inner portion of the tie strip 15 and two complementary second metal members (not shown) are attached to the garment member 17 of the user's hand.

For example, a flexible fastening strip 15 such as fabric is provided. For a better grip, it is expected that the fastening strip 15 and the outer surface of the clothing element 17 have suitable shapes to cover the back of the clothing element 17. It is also expected, for the same reasons and in the case of VELCRO type of fastening means, that almost all of the inner surface of the fastening strip 15 comprises fastening means 16a (see dotted surface on the figure 3a ). For example, the fastening strip 15 has a substantially triangular shape, a flared portion is located on the wrist side, so as to wrap the back of the hand.

According to another example not shown, the fastening strip has a tongue shape of rigid material, such as plastic. This type of material can be preferred in the case where magnetic elements are used.

The fastening strip 15 can be connected to the end of the plate 9 of the removable handle support 8a by an adjustment strap 19 passing in a bar of the end of the plate 9 ( figures 1 and 3a ). The bar results for example from the residue of material between two windows formed in the end of the plate 9.

According to another embodiment shown in figure 9 the end of the plate 9 has three windows forming two bars 20a, 20b for the passage of the adjustment strap 13. It is thus possible to have at least two distinct adjustment positions to adapt the removable handle holder 8b to two sizes different hands. On the other hand, the three windows allow self-locking tightening of the tightening strap 19 when the latter passes successively in at least two of the three windows.

In the example shown on the figure 1 , the adjustment strap 19 forms a loop, a first end of which is anchored to the fastening strip 15 and the second end has connection means with connecting means complementary to the outer surface of the fastening strip 15. connecting means and the complementary connecting means comprise ribbons respectively provided with loops and hooks, so as to form a VELCRO type connection. According to another example not shown, one of the two lights has a beveled edge to fix, in known manner, the second free end of the adjustment strap 19.

It can further be provided that the windows have substantially an arcuate shape allowing a lateral sliding of the adjustment strap 19, for example by having an arc of a circle wider than the width of the adjustment strap 19 ( figure 9 ). It thus facilitates the pivoting of the fastening strip 15 relative to the removable handle holder 8a, 8b, which increases the freedom of pivoting of the hand around the handle 2.

According to a second embodiment visible on the figures 9 and 10 , the removable handle support 8b has a retaining buttress 21 whose one end is connected to the plate 9 and a second end is shaped to cooperate with the handle 2 and support the plate 9 of the removable handle holder 8b.

The second end of the retaining buttress 21 comprises for example two teeth 22a, 22b to cooperate with a recess 7 and a relief 6 of the handle 2. The entrance is for example an arc. The more one presses on the plate 9 and more the entry engages in the hollow 7 of the handle 2, bearing on the relief 6 of the handle 2 below, thus distributing the load on the stay thus formed.

According to another embodiment of the support stick 3 represented in figure 11 , the longitudinal rod 4 has a succession of at least two reliefs 6 and a hollow 7 interposed between the two reliefs 6 at a position of equilibrium located in the vicinity of the center of gravity of the support stick 3, substantially in the middle of the length formed by the rod 4 and the handle 2. The reliefs 6 and the recess 7 located in the vicinity of the center of gravity of the support stick 3 are configured to cooperate with the fork 10 of the removable handle holder 8a, 8b. Thus, the user can, if he wishes, continue his race without the use of poles but by wearing them horizontally. The removable handle holder 8a, 8b is clipped in the vicinity of the center of gravity, the weight of the support stick is balanced on both sides of the holding position so that its porting is facilitated.

We can also provide more reliefs 6 and troughs 7 in the vicinity of the center of gravity, so as to facilitate and improve the grip of the rod 4 by the user. It is also conceivable that the longitudinal succession of reliefs 6 and recesses 7 of the handle 2 extends to this longitudinal equilibrium position.

The figure 12 discloses a third embodiment of the invention in which the removable handle holder 8c is placed above the portion of the gripping portion 100 which is gripped by the user's hand. The removable handle holder 80 is an anchor part of a strap designed to surround the hand or the wrist of the user. In this case, the stop of the longitudinal movement of the hand along the stick is done through the retention operated by the strap.

As can be seen at figure 12 , the strap is constituted by the association of a fastening strip 15 connected to the removable handle holder 8c and a mitten 17. Fastening means, not visible in this view, solidarize the fastening strip The attachment means are similar to those described above and may be self-gripping tapes.

The means for stopping the longitudinal movement of the hand also comprise a rigid tongue 101 provided to receive the thumb.

The figure 13 discloses a fourth embodiment of the invention in which as in the previous mode, the removable handle holder 8d is placed above the portion grasped by the hand of the user. The removable handle holder 8d will not be described in detail here in that it is an element similar to that described for the first embodiment and visible to the Figures 3a and 3b . The difference lies in the fact that a flexible type of strap is attached laterally to the removable handle support.

Before grabbing the stick, the user passes his hand in the loop of the strap 103. Thus the hand can no longer slide along the stick.

The invention is not limited to the few embodiments described here by way of example. In particular it can be provided that the removable handle support slides on the gripping portion 100 and is fixed thereto in another way by clipping.
