A leg assembly, and a shock absorption mechanism for a pole are provided. The shock absorption mechanism comprises a pole body and a leg assembly, wherein the leg assembly comprises a support leg, a tray surrounding the support leg, and a connecting sleeve for connecting the pole body inserting from the top of the support leg. When a bottom of the pole body is inserted into the connecting sleeve and tightly resists against the elastic limiting clamps, the elastic limiting clamps will be pushed outward and limited in the guiding slots of the support leg, so that the connecting sleeve with the pole body can move upward and downward relative to the support leg. There is a mounting space for the shock absorption spring between the support leg and the connecting sleeve, and the support leg has a trend of moving downward due to resistance from the shock absorption spring.

A ski pole accessory includes at least one pole connector, a supporting base, and a plurality of tapering strings forming a streamer. The supporting base has a securing element connected to the pole connector, and a length that extends along at least a majority of a pole length of a ski pole when the supporting base is attached to the ski pole. The strings are individually connected to and extending from the supporting base. The strings extend along at least a majority of the length of the supporting base with each string being offset from an adjacent string of the plurality of strings along the supporting base.

An instructional device for an instructor to use with a student for downhill skiing is disclosed. In use, the instructor skis to the side and behind the student skier. A curved extension member is provided at the end of a shaft and is placed against the student skier's midsection to provide stability and balance for the student. Two student handles can be attached to the extension member. The student handles serve two purposes. The device can be easily converted for use either from the student's right side or left side, depending on the instructor's preference. Second, the student handles can be added as the student progresses to help correctly position the student's hands and develop good posture for the eventual use of ski poles. An instructor handle is located along the shaft. The instructor handle may be adjustable along the length of the shaft.

The invention provides an ergonomic handle for a mobility device comprising a central column grip region that has its lower portion extend outwards, forming a support ledge, for an ulnar portion of a user's hand upon the hand gripping the central column grip region, that extends substantially perpendicular to a longitudinal axis of the central column grip region, surrounding the lower portion of the grip region, the handle having a slit cavity that splits the support ledge and extends upward into the central column grip region, and the support ledge having an incline ledge portion that is sloped downward at a rear area of the support ledge.

The present invention discloses an automatic telescopic pole, which comprises a first pole section having an upper end and a lower end; a second pole section telescopically disposed inside the first pole section; a handle disposed on the upper end of the first pole section; an elastic member disposed between the second pole section and the first pole section; a clasp-type telescopic locking device disposed between the second pole section and the first pole section; a driving rod having an upper end and a lower end, and disposed in the clasp-type telescopic locking device along a longitudinal direction of the first pole section; wherein, a button mechanism having a button is disposed on the handle; and, a lock catch is slideably disposed on the handle and in front of the button mechanism.

A pole handle (1), for walking sticks and the like, having a handle body (3) and a hook-like device (14) for fastening a hand strap or of a glove. A displaceable latch-in structure (7) is arranged in the region of the hook-like device (14) such that a eyelet-form device (42), which is provided on the hand strap or glove and is pushed into the hook-like device (14) essentially from above, is fixed in the hook-like device (14) with self-latching action. The pole handle (1) does not have any structure that can displace or free the latch-in structure (7), such that an eyelet-form device (42) pushed into the hook-like device (14) can be removed from a confined region (15) in a force-free manner or counter to a relatively low force, the hand strap or glove being separated from the pole handle (1) in the process.

Technologies are disclosed herein for controlling a head-mountable heads-up display system comprising a heads-up display unit and a hand cover. The hand cover includes a plurality of input elements located on appendages thereof that are configured to cause the hand cover to transmit input signals to the heads-up display unit. The heads-up display unit is configured to display virtual image content within a field of view of a user. As a result of receiving a user input, the heads-up display unit may display virtual image content based on a user input. The heads-up display unit updates the virtual image content as a result of receiving an input signal corresponding to an interaction between a pair of input elements of the hand cover. The heads-up display system may be useable in connection with a system of an outdoor recreational area to obtain information regarding the outdoor recreational area.

An embodiment includes a walking stick. The walking stick includes a rod assembly, a water purification assembly, and a manual pump. The rod assembly extends from a first end to a second end that is opposite the first end along a longitudinal direction of the rod assembly. The rod assembly includes at least one rod portion. The water purification assembly is integrated with the rod assembly. The manual pump is configured to impose a pressure gradient in the water purification assembly. The manual pump includes a plunger that is physically coupled to a handle portion. Motion of the plunger relative to the water purification assembly draws water into an inlet tube that is positioned in the rod portion and through the water purification assembly. The motion of the plunger results from translation of the handle portion in substantially the longitudinal direction of the rod assembly.

A system for monitoring performance of a user includes at least one processor, and at least one memory including a computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the system to perform operations including obtaining force data measured by at least one force sensor coupled with one or more poles and velocity data measured by at least one sensor for measuring velocity of the user, determining poling power based on the force data and the velocity data, and outputting a poling power indicator based on the determined poling power.
