  • Publication number: 20110018250
    Abstract: A stick snow ring (1) for a stick is described, with a stick holder (5) for receiving a stick tube. According to the invention, the stick snow ring (1) is characterized in that the snow ring region (2, 3) is designed as an essentially rigid disc and is fastened by means of a joint (4) in a manner such that it can rotate freely about a stick axis (A) and such that it can tilt about a tilt axis (B) over an angular range of 150°. The size of the snow ring can preferably be adapted individually to various use conditions.

  • Publication number: 20100218347
    Abstract: The invention relates to a pole grip (1), particularly for walking sticks, trekking poles, alpine ski poles, 5 cross-country ski poles and Nordic walking poles, comprising a grip body (3) and a hook-like device (14) for attaching a hand-retaining device particularly provided in the form of a hand strap or a glove. Latching means (6, 11) are placed in the area of the 10 hook-like device (14) in such a manner that a strapshaped, ring-shaped or eyelet-shaped device (33), which is inserted from above into the hook-like device (14) and which is provided on a hand-retaining device, is fixed in the hook-like device (14) in a self-latching 15 manner. This simple and self-latching mechanism enormously simplifies use and is preferably combined with a safety release in the event of a heavy load acting in the opening direction of the hook-like device.

  • Patent number: 7229101
    Abstract: A stick, such as a trekking stick, ski pole or walking stick, is provided with a shock absorber between a first and a second tubular section of a stick shaft that is equipped with a handle and a stick tip. According to the invention, the shock absorber comprises a guide sleeve, which is held in a rotationally fixed manner in a tubular section and In which a damping rod that is held in an axially fixed manner on the other tubular section Is guided and a compression spring device, operating between the guide sleeve and the damping rod. The aim of the invention is to obtain softer shock absorbing characteristics and resilience characteristics that are less abrupt with minimal kickback. This is achieved by the provision of an elastomer spring in the compression spring device, said spring being located in series with a helical compression spring.

  • Patent number: 7226084
    Abstract: A pole handle (10) provided with a hand retaining device (11) in the form of a toggle strap or a glove which can become detachably engaged with the pole handle (10) by means of a connecting element (64) disposed on the hand retaining device (11). A second connecting element (46) which cooperates with the first connecting element (64) is provided in a recess (26) of the pole handle and can be moved by means of an actuating member (41), which is accessible in the handle head region. In order to ensure a simpler and more ergonomic detachable fixing of the hand retaining device, access to the pole handle recess (26) is provided by means of a longitudinal slit (31) which extends from above to below the area of movement of the second connecting element (46), and parallel or inclined in relation to the longitudinal pole handle axis (17).
