Sports equipment

Abstract

The present invention relates to a kind of sports equipment. The sports equipment includes a frame and an upper body exercise device arranged on the frame, wherein the upper body exercise device mainly includes a left-hand object, a right-hand object and a power transmission system. The power transmission system has two opposite ends respectively connected to the aforementioned two objects, and an elastic component is arranged between the aforementioned two ends. When any object moves from its starting position to the end position, it will drive the corresponding end of the force transmission system to produce a corresponding positive displacement, and the elastic component will increase the deformation and elastic force correspondingly; relatively, when a certain end of the force transmission system moves When the displacement is reversed, it will drive the corresponding object to move from its end position to the starting position, and the elastic component will reduce the deformation and elastic force correspondingly, that is, the elastic force of the elastic component will make the positive displacement of one end and the reverse displacement of the other end tend to match. The invention allows the user to simultaneously exercise the upper body and the lower body in a natural and comfortable state.

Description

technical field [0001] The present invention relates to sports equipment, in particular to a sports equipment that includes an upper body exercise device that can be used in conjunction with a lower body exercise device, thereby allowing users to perform whole-body exercises. Background technique [0002] Common aerobic indoor sports equipment, such as treadmills, exercise bikes, steppers, slide machines, etc., are all sports equipment for users to exercise their lower body. However, recently, more and more such sports equipments have added the function of hand movement (commonly known as "dual-function (dual-function)"), so that the user can exercise the upper body and the lower body at the same time. [0003] For example, U.S. Patent No. 4,625,962, No. 6,123,649, and early published patent cases such as No. 2005 / 0124471 and No. 2005 / 0209059 all disclose dual-function sports equipment based on treadmills. In the sports equipment disclosed in these patent documents, the upp...

Problems solved by technology

[0004] 1. In most structures, the left-hand grip and the right-hand grip are independent of each other and do not affect each other. That is, the aforementioned upper body exercise device is equipped with two sets of recovery mechanisms (mainly elastic components), which respectively provide a recovery force to move the corresponding grip. The collection is towards the starting point, so the cost is higher

Some structures even set up two sets of resistance mechanisms, providing different resistance sources for the left hand and right hand respectively, which not only is troublesome to adjust, but also increases the cost

[0005] 2. When the left and right handles each have a set of corresponding recovery mechanisms, in each arm swing cycle, the elastic components of each set of recovery mechanisms must undergo a large elastic deformation and recovery, so it is easy to elastic fatigue, lower service life

[0006] 3. In some structures, the grip of the left hand and the grip of the right hand pull each other rigidly and instantly, that is, the distance that one hand pulls with force will cause the other hand to be pulled back synchronously, resulting in stiff arm movements. Natural, and may even disrupt body balance, causing movement hazards

[0007] In addition, although the upper body exercise devices in U.S. Patent No. 5,527,245 and No. 6,599,223 are designed to be used in conjunction with the lower body exercise device, they basically do not allow the hands to move in an alternating left-right and full-range swing mode, so the arm movement is relatively slow. Incomplete, and the movement posture of the upper body and the lower body does not work well together

Furthermore, these two cases each use a single recovery mechanism to recover the left and right handles, but they both set "moving pulleys" between the recovery mechanism and the aforementioned two handles (note: here the fingers will float along their radial direction. pulley), which reduces the power efficiency of the recovery mechanism (and resistance mechanism), and relatively wastes the manufacturing cost
