摘要： An improved snowshoe includes a frame at least partially covered by a membrane, a front claw, and biased mounting means for pivotally attaching the front claw to the frame at an offset relative to a neutral frame plane. The biased mounting permits the user's foot to pivot the front claw downward increasing friction with the underlying terrain, but also urges the snowshoe to pivot toward an angle restoring the offset when the snowshoe is lifted. This results in the back of the snowshoe being urged downward, minimizing snow throwing by the snowshoe back, without producing dragging. At the same time, the front of the snowshoe is urged upward, tending not to trip the user. The biased mounting preferably includes at least one resilient strap attached to the frame and, at the strap center, to the front claw. The preferred embodiment includes a rear cleat mounted to the upper membrane surface, and including at least one wall projecting downward through the membrane. This rear cleat minimizes snowshoe skating and allows the snowshoe to be used confidently downhill. Alternatively, a rear cleat may be mounted to the back and/or sides of the snowshoe frame. Further, a rear cleat according to the present invention may be retrofitted to an existing snowshoe to minimize rear sway and allow confident downhill use. Alternatively, a rear cleat according to the present invention may be retrofitted to the user's boot.
摘要翻译：改进的雪鞋包括至少部分地被膜覆盖的框架，前爪和用于相对于中立框架平面以偏移枢转地将前爪枢转地附接到框架的偏置安装装置。偏置的安装允许使用者的脚将前爪向下枢转以增加与下面的地形的摩擦力，但是还促使雪鞋在雪靴被提升时朝着恢复偏移的角度枢转。这导致雪橇的后面被向下推动，最大限度地减少了雪橇后退的积雪，而不会产生拖曳。同时，雪鞋的前面被向上推，倾向于不让使用者跳闸。偏置安装件优选地包括附接到框架的至少一个弹性带，并且在带中心处包括至前爪。优选实施例包括安装到上膜表面的后防滑板，并且包括至少一个向下突出穿过膜的壁。这种后挡板最大限度地减少了雪鞋滑冰，并允许雪鞋自信地使用下坡。或者，后防滑板可以安装到雪鞋框架的后部和/或侧面。此外，根据本发明的后防滑板可以被改装到现有的雪橇上，以最小化后摆动并且允许自下而上的使用。或者，根据本发明的后防滑钉可以被改装到使用者的靴子上。

摘要： An apparatus for measuring the angle of flexure between an elongated body limb and the portion of the body to which the limb is affected. The apparatus can be used to monitor flexure between a thigh and lower portion of a human leg. The apparatus is useful during the performance of rehabilitative knee-bends includes means for coupling the apparatus to the thigh, and two gravity actuated switches for monitoring the angle between a long axis of the thigh and a vertical axis. The apparatus indicates when the extreme points of the knee-bend have been crossed.

摘要： A snowshoe is constructed of molded plastic nose and tail pieces, both connected to a pair of rigid rails to complete the snowshoe frame. A stretched deck membrane, in an area over the heel of a user's shoe or boot, has left and right sides secured to the rails, and preferably is also supported on the tail piece and on aft portions of the nose piece. In one embodiment the rails are of tubular metal, secured to aft portions of the nose piece and forward portions of the tail piece via reinforced, shaped cavities in the molded plastic, contoured to receive the rails. The snowshoe construction is efficient in assembly and cost because there is no need for bends in the rails, the molded plastic components are relatively inexpensive, and snowshoes of different lengths may be produced simply by changing the lengths of the rails and of the deck membrane. In one specific embodiment the rails are extendable, as with telescopically fitted tubing sections, so that the length of a snowshoe may be adjusted for different snow conditions.

摘要： An apparatus for measuring the angle A of flexure of a joint between longitudinal axes of adjacent, jointed body parts includes first and second coupling mechanisms for fixture respectively to the first and second body parts. Each of the coupling mechanisms is fixed to its respective body part at a specified distance from the joint being measured. The apparatus further includes a measuring device for generating a signal representative of the direct, linear distance between the coupling mechanisms as the joint passes through a range of motion. A computing device operates in response to the signal generated by the measuring device to determine the angle A in accordance with the law of cosines. An advantage of the apparatus is that it is significantly tolerant of improper placement of the coupling mechanisms.

摘要： A snowshoe has a front claw and shoe harness assembly including a molded, conclave footpad. The footpad has front-to-back concavity so as to cradle the ball of the user's foot, helping the user locate the foot properly and preventing slippage fore-and-aft and rotationally relative to the snowshoe. In preferred embodiments, the contoured footpad is of a rubbery, somewhat compliant material to further promote friction and cradling of the ball of the shoe.
