  • Patent number: 10702738
    Abstract: A treadmill includes a base frame and an one-way damping device. The one-way damping device includes a rotatable braking plate, an one-way clutch, and a resistance unit. The resistance unit is fixedly mounted to the base frame and abuts against the braking plate. The one-way clutch is sleeved on one of two rotating shafts of the base frame, is not engaged with the braking plate when the rotating shafts are rotated in a first rotational direction, and is engaged with the braking plate when the rotating shafts are rotated in a second rotational direction, which in turn drives the braking plate to co-rotate against a frictional force between the braking plate and the resistance unit.

  • Patent number: 9926082
    Abstract: An opening portion of a vent member is prevented from being blocked, and thus ventilation is reliably performed. A plurality of opening portions (40A, 40B) are formed in a single vent stringer (20), and thus even in a case where one of the opening portions (40A, 40B) is blocked, ventilation is secured by the other opening portion. At this time, since the opening portions (40A, 40B) are formed in surfaces different from each other in the vent stringer (20), a possibility that both the opening portions (40A, 40B) may be simultaneously blocked is less.

  • Patent number: 8105219
    Abstract: A training apparatus for use by flyers in a cheerleading squad includes a stable base assembly, a balancing assembly, and a fixed or adjustable column located between the stable base assembly and the balancing assembly. The balancing assembly includes a deflectably resilient member and a standing surface that promotes proper alignment and mimics the feel that a flyer experiences when being supported by a base cheerleader. The deflectably resilient member provides two degrees of freedom of movement to the standing surface when the standing surface is under an external load. The standing surface preferably provides about the same standing area that typically provided by a base cheerleader. The column may be a fluid-activated cylinder that moves between a first and second vertical position and simulates a flyer being raised by the base.

Each cushioning device (22) includes a spring (46) that may be attached at each of its ends to first and second caps (48, 50). The spring (46) includes longitudinally aligned regions (58, 60) interposed between the caps (48, 50). The region (58) exhibits a lower spring rate (64) than a spring rate (66) of the other region 60. In response to an imposed force, the first region (58) of spring (46) first compresses. When the imposed force is great enough, due to a user's weight, the second region (60) of spring (46) will then compress.

  • Patent number: 6598365
    Abstract: An impact and energy absorbing product for floors, walls, panels, crash mats and other flat surfaces. More particularly, the invention teaches the usage of coiled springs in conjunction with polymeric materials or metals such as titanium or steel, to help absorb and dissipate forces of humans and other objects coming in contact with said flat surfaces. Depending upon the exact environment in which the same are to be used, the coiled springs may be constructed of polymers or metals such as titanium or steel—lightweight, yet durable materials to accomplish the purposes of the invention. In the preferred mode of attachment, an insert is fitted to each end of each spring, with a flared insert then placed into a molded female slot upon a flat surface to hold the spring in place. Thus, a floor or wall surface may comprise a series of female slots such that multiple springs can easily slide therein.
