Title:
【発明の名称】長さ調節自在スキー棒および円筒状シャフトのクランプ
Document Type and Number:
Japanese Patent JP2656216
Kind Code:
B2
Abstract:
An adjustable length ski pole (4) includes two telescopically fitted together ski pole halves (4a, 4b), and a clamp (16, 116) disposed about the joint between the two pole halves. The clamp (16, 116) includes a resilient tubular member (20, 120) having an annular sidewall (24, 124) which defines a cylindrical bore (28, 128), where the sidewall (24, 124) is formed with a longitudinally extending gap (32, 132) to allow the tubular member (20, 120) to be selectively biased to reduce the gap width and thus the diameter of the bore, or to enlarge the gap width and thus the diameter of the bore. The gap (32, 132) defines first (32a, 132a) and second (32b, 132b) opposing sidewall edges having coaxial first (34, 134) and second (36, 136) openings respectively. The clamp (16, 116) also includes a pin (40, 140) anchored at one end in the first opening to extend with the other end through the second opening, and a lever arm (48, 148) pivotally attached at one end to the other end of the pin (40, 140), to move between a clamped position, in which the lever arm (48, 148) lies in contact with the ski pole to bias the first and second sidewall edges towards one another, and an unclamped position, in which the lever arm is pivoted away from the ski pole to allow the gap (32, 132) to widen. The sidewall edge includes a camming surface (44, 144) and the lever arm (48, 148) includes a camming knuckle (62, 162) formed at said one end to contact the camming surface (44, 144) and force the second sidewall edge toward the first sidewall edge when the lever arm (48, 148) is pivoted to the clamped position, to thereby secure the two pole halves (4a, 4b) in a fixed position relative to one another.
