    Abstract: The present invention relates to an energy absorbing apparatus. Specifically, the apparatus comprises a first disk and a second disk atop the first disk, and a plurality of collapsible arms around the perimeter of the disks connecting the first disk and the second disk, and an elastic material disposed between at least two of the collapsible arms, wherein collapsing of the arms causes the elastic material to stretch, storing kinetic energy from the vertical direction as potential energy in the horizontal direction, wherein release of the potential energy from the elastic material causes the arms to return to an uncollapsed state. Systems utilizing the energy absorbing apparatus, methods of making and methods of using the same are further provided.

Provision is made for adjusting the position of the pivotal connection between the link and the gas spring lengthwise of the link, and for adjusting the position of the pivotal connection of the gas spring to the frame in a direction toward or away from the point of articulation of the pendulum lever to the frame. Guides for the load are provided, comprising rollers mounted on the frame in between which a vertical member slides vertically.

  • Patent number: 5195709
    Abstract: A supporting structure for supporting a TV set on an armrest of a seat of an aircraft or other vehicle so that the TV set can be turned in a vertical plane between an operating position outside a cavity formed in the front portion of the armrest and a housing position within the cavity, can be turned about a vertical axis at the operating position, and can be tilted with respect to the vertical axis. The supporting structure includes a hinge mechanism provided at the front upper end of the cavity, and a turning mechanism supported on the hinge mechanism and supporting the TV set so that the TV set can be turned at the operating position in both horizontal and vertical planes. A hinge pin included in the hinge mechanism is provided at one end with a diametrical through hole expanding toward the opposite open ends.

  • Patent number: 5145020
    Abstract: A suspension system for a wheelchair comprises a frame, a pivot bar mounted to the frame through a hinge point, and a seat mounted on the pivot bar. The pivot bar is supported from the frame by a shock absorber and a helical spring so that impacts transferred to the frame through the wheelchair wheels are partially decoupled from the movement of the seat. The movement of the seat is constrained in a single plane along the longitudinal axis of the wheelchair.

  • Patent number: 4881350
    Abstract: An anti-earthquake structure insulating the kinetic energy of earthquake from buildings, which is constructed between a building and the construction site thereof, including a plurality of supporting layers having multiple ball seats, plural ball members correspondingly disposed on and pressed between said ball seats with extremely small rolling friction thereagainst, and a plurality of sliding block linkages disposed between the building and the supporting layers, whereby horizontal displacement of the construction site can apply no horizontal force to the supporting layers, and consequently, the building will remain stable and rigid, the sliding block linkages further converting vertical wobbling force into horizontal force, permitting the horizontal force to be absorbed by multiple buffer springs via lever devices.

  • Patent number: 4801122
    Abstract: An apparatus for supporting an object on a base for isolating the object from movement of the base, typically an art object, instrument, case, or housing for projection during seismic activity. The apparatus includes a base plate for attachment to the base, with a frame positioned on the base plate and adapted for omni-directional movement over the base plate. A lever is pivotally mounted on the frame and is connected to a spring, typically by a cable. The lever is also connected to the base plate, typically by another cable, with movement of the base plate moving the lever and extending the spring, after which the spring retracts, restoring the apparatus to the rest position.

  • Patent number: 4681292
    Abstract: Horizontal pneumatic shock absorbers are connected through gears and levers to convert the longitudinal control of the shock absorbers to vertical control of seat frames of vehicles. Particularly, a preferred embodiment of a resilient support has sufficiently low height to permit placement of the support between the seat and the frame of a motorcycle for supporting the seat at a normal level. The preferred embodiment has, in addition to a pneumatic shock absorber for support, a shock absorber applying an opposing force for controlling bounce. Also, spring couplings connect the levers for supporting the seat to provide resilience for cushioning rapid shocks of moderate intensity while the shock absorbers function more flowly for longer excursions.

  • Patent number: 4648655
    Abstract: A tractor seat of the type having a seat pan 14 which is hooked on to a vertically movable spring biassed carriage 12, so that the seat pan can be released and moved out of the way of a standing driver, has a latch device 18 comprising a headed pin 20 secured to the pan 14 and a catch plate 22 secured to the carriage and formed with an aperture 22a for receiving the headed pin 20. The catch plate is resilient so that it can be bent away from the pin to release the seat pan. In particular the aperture tapers from the lower end normally occupied by the pin to an upper end through which the head of the pin cannot pass, so that accidental lifting of the pan will lock the headed pin within the aperture.
