  • Patent number: 7845660
    Abstract: The invention relates to an anti-roll/pitch system for use in a vehicle, in which a first mass, for instance a cabin, is suspended to a second mass, for instance a chassis, by means of a bearing arm, which is pivotally connected to the second mass around a pivot axis, via spring means. The anti-roll/pitch system comprises means to adjust a point of application of a spring force acting on the bearing arm, so as to adjust a moment exerted by said spring force on said bearing arm to counteract a load exerted on the bearing arm by the first mass. The spring force is exerted on the bearing arm through a flexible, elongated member, such as a string or cable, which takes up little space when adjusting the point of application. The invention furthermore relates to a built-in unit and a vehicle, equipped with an anti-roll/pitch system according to the invention.

  • Patent number: 5913892
    Abstract: A compressor fixture structure for a refrigerator comprises a plurality of compressor fixture structure units. Each of the compressor fixture structure units includes a support, a moving member, a spring, a compressor support, a fixing shaft, and hollow cylindrical buffer members. The support has a first spring fixing member on the center portion thereof and two side walls at both ends each upper portion of which is outwardly slanted. The moving members have an upper plate and a lower plate and a second spring fixing member formed on the lower plate. The spring is fixedly inserted between the first spring fixing member and the second spring fixing member. The compressor support is placed on the moving member. The fixing shaft is inserted through the moving member and the compressor support. The two hollow cylindrical buffer members are fixed between the slanted upper portion and the lower plate, respectively.

  • Patent number: 5765803
    Abstract: A suspension system for a seat for a vehicle having a base frame rigidly attached to the vehicle. The front of a seat support frame is pivotally moveable with respect to the base frame. Springs mounted between the seat support frame and the base frame cushion the seat from forces imparted while driving the vehicle on irregular surfaces. The springs further limit the pivotal movement of the seat support frame with respect to the base frame. There are shock absorbers for dissipating energy absorbed by the springs. The pivotal movement of the seat is around two different axes of rotation, one of the axes being a horizontal axis extending across the width of the vehicle and the other axis being a longitudinal axis extending from the front to the rear of the vehicle.

  • Patent number: 5765802
    Abstract: A vehicle seat suspension includes a bottom frame adapted to be mounted on the vehicle and a top frame located above the bottom frame and adapted to support a seat thereon. A substantially fully collapsible scissors linkage is interconnected between the bottom frame and the top frame enabling the bottom frame and the top frame to move relative to each other substantially in parallelism. A biasing arrangement is disposed between the top frame and the bottom frame and has a preload force urging the top frame away from the bottom frame. A first adjustment mechanism is located in the top frame and selectively enables fore and aft adjustment of the top frame relative to the bottom frame.

  • Patent number: 5758859
    Abstract: A land vehicle seat assembly for absorbing explosive shocks is mounted on e vehicle's floor. The assembly has an anti-friction pad on the floor. A base plate on the pad swings around a pin fixed to the floor at the front of the plate. Horizontal shock absorbers at either side of the plate deceleratingly retard swinging of the plate. Stops at the sides of the plate limit plate swing. The assembly includes a pair of upright rails fixed to the plate and a seat slidable on the rails. A light duty unit such as a pneumatic spring or a shock absorber connects to the plate and seat. A heavy duty shock absorber, responsive only to shocks above a certain power, is connected to the plate. The heavy duty shock absorber can absorb shocks an order of magnitude greater than does the light duty unit.

  • Patent number: 5725186
    Abstract: Adapter bracket mechanisms for securing various roll-up signs to a sign stand. The bracket mechanisms are positioned vertically upright from the base of a sign stand. The adapter bracket mechanisms hold the lower end of the vertical cross brace of the roll-up sign. The mechanisms include a U-shaped channel and either a slide bar or pivoting lever arm member for enclosing the cross brace within the channel. A threaded turn-lock member securely holds the sign in the adapter bracket mechanism. If desired, a protector member can be used to help hold the vertical cross brace in the bracket mechanism and protect the cross brace from possible damage. Another embodiment utilizes a threaded knob to wedge the vertical cross brace in the channel.

  • Patent number: 5386962
    Abstract: A mount for a compressor or the like which sits on a base includes a top surface which is securable to the base. The top surface defines a well having a floor. An opening is formed in the bottom of the floor and a shaft extends from beneath the well floor to above the upper surface. The shaft includes a lower flange positioned below the well floor and an upper flange positioned above the top surface. A spring is positioned between said well floor and the top flange to absorb vibrations and any resulting shock produced by the compressor. A pair of upwardly extending generally perpendicular walls are provided on the upper surface to prevent the spring from engaging the upper surface or deflecting excessively. The walls and the upper flange are sized such that when the shaft moves with respect to the well, the upper flange will contact the wall before the spring contacts the upper surface or deflects excessively.
