  • Patent number: 10264886
    Abstract: A pivot shaft (10) which is a first shaft member coupled to a supporting member, an inner cylinder (12) which is a second shaft member coupled to a supported member, and an outer cylinder (14) which is a third shaft member are disposed to be approximately coaxial with each other and disposed radially in multiple layers. The pivot shaft (10) and the inner cylinder (12) are coupled to each other through a first rubber-like elastic member (11), and the inner cylinder (12) and the outer cylinder (14) are coupled to each other through a second rubber-like elastic member (13). The total reaction force is increased by restricting the rotation of the outer cylinder (14) by means of an operating pin (19) which is a reaction force adjusting part and thereby adding a reaction force resulting from the second rubber-like elastic member (13) to a base reaction force resulting from the first rubber-like elastic member (11).

  • Patent number: 9241573
    Abstract: A resilient-support adjusting device of a chair backrest includes a base and a spring-tensioning brace and a backrest-fastening seat pivotally connected to two ends of the base. The backrest is fixed to the backrest-fastening seat. A spring is tensioned between the spring-tensioning brace and the backrest-fastening seat. The base contains upper and lower abutting members that have inclined abutting surfaces abutting against each other. The upper abutting member has an upper end abutting against a swinging end of the spring-tensioning brace. The lower abutting member has an engaging member that can be driven by the operating lever to rotate. The engaging member and the lower abutting member engage with each other. When rotated, the operating lever drives the spring-tensioning brace to swing and draw the spring. The spring thus draws the backrest-fastening seat harder, making the backrest have stronger backward resilient support.

  • Patent number: 6676101
    Abstract: A horizontal-motion vibration isolation system for supporting an object in an equilibrium position relative to a base while suppressing the transmission of horizontal vibratory motion between the object and the base includes a plurality of columns, each column having a rigid member with a first end and a second end. A tilt mechanism is operatively connected to each first end of the rigid members and the object. Likewise, a tilt mechanism is operatively connected to each second end of the rigid members and the base. Each tilt mechanism exhibits a tilt rotational stiffness and the horizontal translation of the object relative to the base causes tilt rotation of the columns. The tilt rotational stiffness of the tilt mechanisms is approximately proportional to the compression load transmitted to the columns by the weight of the object, so that the horizontal natural frequency of the system is nearly insensitive to the payload weight.

  • Patent number: 6663076
    Abstract: A seat post includes a tube having a stop secured in the middle portion. A pipe is slidably extended through the stop. A rod is secured to the pipe and has a seat cushion secured on top. A spring may bias the pad to engage with a stop of the tube and to cushion the rod. A bolt is threaded to the tube and engaged with the pad for adjusting the spring force of the pad and the spring against the pipe. A barrel is secured on the tube and one or more studs are engaged between the barrel and the rod for preventing the rod from rotating relative to the barrel.

  • Patent number: 6557816
    Abstract: A motor mounting structure having a motor and a mounting portion to which the motor is mounted. When an external force resulting from a load acting in a direction orthogonal to a motor shaft is applied to the shaft, a hardness or configuration of an elastic member disposed between the motor and the mounting portion to which the motor is mounted changes. Alternatively, a configuration of the mounting portion may be changed and the motor mounted such that the motor shaft is parallel to a set target mounting direction. Accordingly, an unbalanced load is not partially applied to a driving force transmission mechanism at the time the motor is rotated, and an excessive load is not placed on the motor.

  • Publication number: 20020195535
    Abstract: A chair height adjustment mechanism includes an energy storage unit which has a compressible fluid. This compressible fluid allows the compressible fluid displaced by the piston rod entering the cylinder, to store energy for subsequent use as the chair seat is raised. This fluid may be of the type that has a dual phase at room temperature such that increase in pressure on the compressible fluid causes a portion of that compressible fluid to transition from gaseous phase to liquid phase. This makes the energy storage unit a constant force spring. The features of this constant force spring may be used in a conventional piston cylinder, shock absorbing device, as well.

  • Patent number: 6102354
    Abstract: A device for cushioning shocks is provided. A relatively unstable, collapsible elastomeric member which has guides integrally formed thereon, is surrounded by a guide sleeve which provides controlled deflection as well as damping for the elastomeric member. A piston is used to collapse the elastomeric member. The cush of the present invention can be utilized in hydraulic systems where an elastomeric bladder provides primary energy storage and in other applications where the cush of the present invention is the primary damper. This cush can be preloaded and, where desired, can be provided with the capability to adjust the preload.

  • Patent number: 6098937
    Abstract: A support stand, support stand assembly, and method of making the same with the support stand featuring a base with central hub-like reception area either capped or uncapped at its bottom and a supporting rod that has a diameter less than that of the side wall defining the reception area so as to form an annular gap. An elastomer material, which is preferably a liquid urethane that cures at room temperature, is poured into the gap so as to form an energy management member which acts as a flexible cushioning element by helping to dampen and diffuse rocking forces of the supporting rod with respect to the base. The energy management member also acts to glue the supporting rod to the base through the bonding properties.

  • Patent number: 5558301
    Abstract: In order that the acceleration suffered by the occupant (O) of an aircraft, particularly a rotary-wing aircraft seat in the case of an accident remains below a humanly withstandable limit, no matter what the size of said occupant, a seat is proposed in which a height regulation of the pan or bucket (16), in which the occupant is received, also has the effect of modifying the inclination of the energy absorbers (38). Thus, the vertical component of the retaining force exerted on the pan (16) by said absorbers decreases with the size of the occupant, which leads to the desired result.
