The invention relates to a folding pole (1), normally comprising four pipe sections (7-9), wherein the pipe sections (7-9) are connected to each other by means of plug-in connections while aligned along the pole axis (32) in the assembled state of the folding pole (1), and normally only three pipe sections (8, 8, 9) are still connected to each other by means of a movable connecting element (16) in the folded state, and wherein a pole handle (2) is arranged on a top pipe section (7) and a pole tip (23) is arranged on a bottom pipe section (9). According to the invention, at least one of the plug-in connections is realized by means of an external clamping mechanism (10), wherein the clamping mechanism (10) is fastened to a first pipe section (7), and wherein a second pipe section (8), which has an outside diameter smaller than or nearly equal to the inside diameter of the first pipe section (7), and which is supported in the first pipe section (7) so as to be movable itself, can be fastened in the relative axial position by the external clamping mechanism (10). The further plug-in connections are designed as pure plug-in connections, wherein pipe sections (8, 8, 9) are fastened only in an axial direction in the connected state. The pipe sections (7-9) are connected to each other by means of at least one tension cable (16), which is fastened to the bottom pipe section (9) and to the top pipe section (7) and which is arranged so as to pass through the interior (31) of the at least two middle pipe sections (8, 8). The folding pole (1) is designed in such a way that the folding pole can be transferred from the folded state to the assembled state by connecting the further plug-in connections, and then, with the external clamping mechanism (10) released, pulling the second pipe section (8) out of the first pipe section (7) until the tension cable (16) is under tension, and fastening the external clamping mechanism (10).

The present invention provides a method and a device for modulating one's motion in a sport or recreational activity such as inline skating, skateboarding or snowboarding. The device comprises a collapsible or retractable base having a distal end and a proximal end; and a removably attached motion modulating element on the proximal end and/or the distal end of the base.

A power and stabilizing apparatus for rolling or sliding-based recreational activities is disclosed. The apparatus may include a shafted body coupled to a biased member. The biased member may be a bowed biased member or any other biased member configured to store and release energy during use of the apparatus. The apparatus may also include a shoe coupled to the biased member opposite the body, the shoe having a traction element coupled thereto. The body may be a shafted telescoping body configured to lock in an extended position and lock in a retracted position. The body may be coupled to the bowed biased member with a coupling member having a first leg coupled to the body and a second leg coupled to the bowed biased member.

Folding stick having at least three tubular portions which assembled are interconnected by plug-in connections, and at least two tubular portions are interconnected by a pull cable in the folded state. The plug-in connections have, at one tubular portion, a guide pin provided with a central through-opening for the pull cable and is fastened in this tubular portion by a fastening portion and has a plug region axially opposite. The fastening portion and plug region have a through-opening for the pull cable. A closure plug is removably inserted into the plug region and has an axial slot through which the pull cable can be introduced into the axial through-opening in the radial direction. A tubular protective sheath is provided around the pull cable and is form-fittingly held in or on the closure plug.

An automatic leg tube locking device including a hollow cylinder shaped guide switch and a circular truncated cone shaped guide post which are mutually matched for use. Through holes are evenly formed in the side surface of the guide switch, the through holes are adapted with locking shafts, a transmission mechanism is arranged between the guide switch and the guide post, so that the guide switch vertically moves along the inclined cylinder surface of the guide post and drives the locking shafts to move along the guide post when the guide switch and the guide post rotate relative to each other. A photography tripod, a unipod and a crutch are further provided. The automatic leg tube locking device, the photography tripod, the unipod and the crutch are capable of pulling the leg tube to any position and lock the leg tube automatically in a locking state.

A pole comprising a pole handle and a pole tip, with at least two tube portions located therebetween, which in an assembled state of the pole are connected to one another by means of insertion connections aligned along a longitudinal pole axis A. At least one of the plug connections is realized on a second tube portion by way of a form-fit and/or force-fit locking device, wherein the second tube portion has a smaller the same outer diameter than the inner diameter of a first tube portion, and which can be inserted into the first tube portion, and which can be fixed in the relative axial position by means of the form-fit locking device. On at least one of the plug connections, a tubular sleeve having a clamping element in a receiving groove is arranged between the tubular sleeve and the lower end of the first tubular portion.

For ski poles, walking poles and similar, a length-adjusting arrangement including an inner element 2 and an outer tube 1, there being a locking device 3 on this same first end 11 of the outer tube 1, with which locking device 3 the inner element 2 and the outer tube 1 can be releasably locked in various axial positions relative to each other, there also being a regulating device 4 on the other end 12 of the outer tube 1, with which regulating device 4 the locking device 3 can be manoeuvred, the outer mantle surface of the inner element 1 2 including two or more cut-outs 21 arranged at a distance from each other in the axial direction of the inner 419 element 2, the locking device 3 including a latching element 32 that is axially fixed relative to the outer tube 1 but, relative to this same outer tube 1, is displaceable between a first position where parts of said latching element 32 are inserted in one of said cut-outs 21 and a second position where said latching element 32 is disengaged from said cut-outs 21 and where the latching element 32 being moved, under the influence of a spring member 43, in a direction towards said first position, in which position the inner element 2 and the outer tube 1 are locked in the axial direction relative to each other and where the latching element 32 is moved, under the influence of the regulating device 4, in a direction towards said second position via an axially displaceable control 6, this control 6 being in the space between the outer mantle surface of the inner element 2 and the inner mantle surface of the outer tube 1, said control 6 extending axially from said locking device 3 to said regulating device 4 and where, in said second position, the inner element 2 and the outer tube 1 can be displaced in the axial direction relative to each other.

A ski pole assembly that includes: a ski pole, which defines a cavity; an extension, which is at least partially received by the cavity and is configured to traverse the cavity along a longitudinal axis of the ski pole; and a mounting mechanism that is configured to removably couple an attachment to the extension.

A variety of ski and hiking poles are described. In one aspect, magnets are provided on the pole handles and baskets to facilitate magnetic coupling a pair of poles together in a state suitable for carrying. In some embodiments, a pair of magnets are provided on each side of the handle. In some embodiments, a basket alignment piece is attached to the pole shaft. The alignment piece helps facilitate attachment of the basket to the pole shaft in an orientation that aligns the basket magnets relative to the handle magnets. In another aspect novel wrist straps are described.
