Spring Assisted Patents (Class 472/113)
  • Patent number: 9498673
    Abstract: An exercise device with a swing function includes a main body and a plurality of support mechanisms. The main body has a base which includes a front part and a back part. Each of the plurality of support mechanisms has a height and is abutted upon a ground to sustain the base. The height of each of the plurality of support mechanisms is changeable. When the main body is controlled to drive the base, the base stresses each of the plurality of support mechanisms to change its height. Therefore, the main body can be inclined to any direction to form a swing motion.

  • Patent number: 8033921
    Abstract: A single rider teeter-totter has a support frame and a longitudinal beam member pivotally coupled to the support frame. A seat for a user is attached to a first end of the beam member. A counterbalancing resistance is provided by a plurality of elastic members, each of which is attached at a first end to the support frame. A number of the elastic members appropriate to the weight of the user are secured to a securing station disposed on the beam member. The unused elastic members may be secured to a second securing station attached to the support frame.

  • Patent number: 7413516
    Abstract: A teeter-totter is constructed with a pair of seats mounted at opposite ends of a rocker beam. The seats, when aligned horizontally, are below the pivot point so as to provide a pendular component of motion. The pivot is supported on an overhead framework and the rocker beam is suspended below the pivot to eliminate the pinch points found in conventional teeter-totter designs. A counterbalance mechanism may be incorporated so that users of different weights remain in balance while operating the teeter-totter.

  • Publication number: 20070298944
    Abstract: A safer, more user-friendly spring-balance single-rider teeter-totter includes manual adjustments for both the vertical position of the spring, which adjusts the rest height of the seat, and the horizontal position of the spring from the pivot, which adjusts the counterbalance resistance. A safety cover may be provided for the spring or other counterbalance mechanism.

  • Patent number: 5496237
    Abstract: An exercise apparatus which also serves as an effective training device for mountain bikers. The invention utilizes a frame resembling that of a bicycle's frame. The frame supports handle bars having a gripping portion and two foot pedals. Each pedal is fixable to the frame and adjustable in height. Each foot pedal further has an abrasive upper surface for contact with the sole of a user's shoe. This abrasive upper surface acts to prevent slippage of the user's foot from the pedal. The frame is supported by two legs, one supporting the front part of the frame, the second supporting the rear part of the frame. Each leg is rotatably attached to the frame and oriented in a diagonal direction. The range of motion of each leg is limited by a compression spring which further acts to rotate the legs to their extended state after an external force causes them to retract.

  • Patent number: 5447474
    Abstract: A game apparatus with multiple playing modes includes a base unit, a plank support mounted uprightly on the base unit, and an elongated plank unit. The plank support includes a pair of parallel upright plates, a balancing seat which extends between top ends of the upright plates and which has two ends mounted rotatably on the upright plates, a cylindrical support rod which extends between the upright plates below the balancing seat and which has two ends mounted rotatably on the upright plates, and a positioning beam which extends between the upright plates and which is spaced vertically from the support rod so as to form a clearance therewith.

  • Patent number: RE34407
    Abstract: A water sports apparatus, for simultaneous practicing of a number of types of water sports, being a container having an inclined floor surface and closable lower supply nozzle. Water shooting upwardly over the floor surface flows over an overflow into a supplementary pool which is subdivided into two regions, between which regions is placed a grate, and preferably, on the downstream side of the grate, a backflow valve. On the end of the inclined floor near the supply nozzle is placed an elevated water container, the water from which enables starting of the supercritical torrential flow, until a water quantity necessary for circulation and having sufficient velocity is returned through a return line from the region of the supplementary pool farthest away from the overflow. The region of the supplementary pool near to the overflow enables the athlete to exit from the apparatus without influencing the supercritical torrential stream in the water container.
