  • Patent number: 9605796
    Abstract: A posture holding apparatus including, a base onto which a substance is placed, a supporting member being attached onto the base so that the supporting member swings between a standby state and an active state, and a swinging support member having a returning force for returning the supporting member to the standby state, wherein the swinging support member is structured by a swinging member, a biasing member for applying a biasing force to the swinging member to the standby state, a liquid pressure output member for outputting liquid pressure in response to a weight of the substance, and a displacement amount adjusting member, with which a point of action of the biasing force applied from the biasing member to the supporting member is moved in response to the liquid pressure such that a distance from the pivot to the point of action changes.

  • Patent number: 9239129
    Abstract: A holding force adjusting apparatus to be attached to a posture holding apparatus having a base, a supporting member which is attached onto the base so that the supporting member freely swings between a standby state where the supporting member does not support a substance on the base and an active state where the supporting member supports the substance in an inclination state, and a swinging support member having a biasing force for returning the supporting member to the standby state when the supporting member is inclined, the holding force adjusting apparatus being designed to adjust a biasing force of the swinging support member, the holding force adjusting apparatus including a weighting detection member for detecting weight of the substance to be placed, and a returning force adjusting member for adjusting the bias force according to a detected weight by the weight detecting means.

  • Publication number: 20120186496
    Abstract: The present invention provides a moving apparatus capable of efficiently utilizing work space on a desk, and stabilizing an operating load. The present invention includes a placing portion to place a personal computer, a moving portion to move the personal computer from a use position for using the personal computer to a non-use position different from the use position, and a fixing device to detachably fix the moving portion to a desk. The position of the placing portion is determined by the length of an extension mechanism. The positioning operation to determine the length of the extension mechanism is performed by an operating device that transfers the displacement magnitude of an operating portion to an action portion by hydraulic pressure. The operating load is stabilized because the displacement magnitude is transferred by hydraulic pressure.

  • Patent number: 8099864
    Abstract: The present invention provides a reinforcing bar tie the enables the connection intersecting reinforcing bars. The invention houses a tie made of an elastic member in a reception space, and extrudes it with an extruding member. At this time, the curved portions provided on both ends of the tie advance while guiding portions of a guiding member push them open, and are guided to an intersecting position of two reinforcing bars. Further, by extruding with the extruding member the tie detaches from the guiding member and winds around the intersection of the two reinforcing bars with a force sufficient to couple the two reinforcing bars together.

  • Patent number: 8020486
    Abstract: The objective of the present invention is to provide a device that accurately communicates a subtle variation of an operation side to an action side. Specifically, in the present invention, an operating device is provided to perform a lock release operation of an extension device. The operating device feeds oil to a valve chamber by pressing a piston. When the flow rate of the fed oil is excessive, the valve is pressed to an opening resisting a biasing force of a compressed spring, thereby a rapid increase in the oil supplied to the action section is suppressed. Further, the supplied oil is suppressed to a very small amount by the throttle section, thereby an increase in the operation amount on the action section side is suppressed while maintaining the supply of the oil.
