| 20130187315 | Lockable Gas Spring Arrangement - A lockable gas spring arrangement includes a gas spring with a closed cylinder, a displaceably guided piston and piston rod. A fastening tube fastened with its one end in the region of the free end of the piston rod and on which a locking element is arranged. The locking element is able to be moved substantially radially to the piston rod between an unlocked position permitting a free insertion movement and a locked position bearing against the front face of the cylinder on the piston rod side when the piston rod is extended. The locking element is able to be urged by a spring into its locked position. The locking element is able to be moved manually from its locked position into its unlocked position and is able to be retained automatically in its unlocked position by a retaining device. | 07-25-2013 |

| 20090001637 | Hydraulic Shock Absorber - In a front fork in which a partition wall member is provided in an inner periphery of an inner tube, a working fluid chamber is comparted under the partition wall member and an oil reservoir chamber is comparted over the partition wall member, a main suspension spring is interposed between an upper spring bearing in a piston rod side attached to an outer tube side and a lower spring bearing in a bottom portion side of the inner tube, within the working fluid chamber of the inner tube, and a sub suspension spring is interposed between an upper spring bearing in an upper end portion side of the outer tube side and a lower spring bearing in the partition wall member provided in an inner periphery of the inner tube, within the oil reservoir chamber of the inner tube. | 01-01-2009 |
| 20090045559 | SWITCH HOUSING FOR GAS SPRING - A switch housing is shaped to be coupled to a gas spring and includes a limit switch having a control element which is moved to actuate the limit switch when the gas spring rod moves between first and second positions. The housing includes a cylindrical aperture for receiving the body of a gas spring with one end of the aperture including an annular wall and a coupling for attaching to the rod of a gas spring. In one embodiment the housing mounts the limit switch in offset relationship to the cylindrical aperture with the control element of the switch extending into the aperture to be actuated by the body of a gas spring. | 02-19-2009 |
| 20090057967 | GAS SPRING ASSEMBLY AND METHOD OF MANUFACTURE - A flexible wall and end structure assembly includes a flexible wall and an end structure. The flexible wall is formed from an elastomeric material and a filament structure. A bead wire is formed into an open end of the flexible wall. The end structure is received along the open end of the flexible wall and forms a substantially fluid-tight seal therewith. A portion of the filament structure is compressed between the bead wire and the end structure and extends therefrom in radially-outwardly spaced relation to said end structure. A gas spring assembly including such a flexible wall and end structure assembly is included. A method of manufacture is also included. | 03-05-2009 |
| 20090184447 | FLUID-FILLED TYPE VIBRATION DAMPING DEVICE - A Fluid-filled type vibration damping device, which is configured to be free from the necessity of supplying a continuous application of electricity to a coil so as to maintain a movable valve body in either an opened state or a closed state, is provided. The device includes a cam mechanism, which transmits a rotational drive force of a motor to the movable valve body in the form of a reciprocating drive force. In the device, a first rotation angle switch is connected to a first control switch in series relative to a motor coil, and a second rotation angle switch is connected to a second control switch in parallel relative to the first switch. The first rotation angle switch is turned on in a state of a first angular range θ | 07-23-2009 |
| 20100148412 | HYDRAULIC SHOCK ABSORBER - In a hydraulic shock absorber, a second washer, which is assembled around a lower end projection of a lower spring receiver and is retained to enlarged portions provided at the tip end of the lower end projection so that the enlarged portions are prevented from falling, is attached to a step portion of an axle bracket, and the tip end of an inner tube, which is threadedly engaged with the axle bracket, is supported by the second washer. | 06-17-2010 |
| 20100213650 | LIQUID-FILLED VIBRATION ISOLATOR - A liquid-filled vibration isolator has a first orifice channel providing communication between a pressure receiving chamber and a balancing chamber. One of the pressure receiving chamber and the balancing chamber is communicated via a second orifice channel with an intermediate liquid chamber. The second orifice channel has a shorter distance or a larger cross-sectional area than the first orifice channel. An elastic film member, such as a membrane, separates the intermediate liquid chamber and the other of the pressure receiving chamber and the balancing chamber from each other. A communicating hole of a predetermined size is formed in the elastic film member. An imaginary orifice channel combined from the two orifice channels provides a high damping effect on input vibration of relatively low frequency. As the vibration frequency increases, a gradual transition is made to the damping characteristic of the second orifice channel only. | 08-26-2010 |
| 20140145382 | DIAMETER -VARIABLE CYLINDRICAL AIR PRESSURE SPRING - The invention relates to a diameter-variable cylindrical air pressure spring. The current air pressure spring has the shortcomings of complex structure, insufficient deformation stroke and poor ventilation effect. The diameter-variable cylindrical air pressure spring comprises a spring body, the spring body is formed by at least one hollow cavity body, the sidewall of the cavity body is of a multilayered structure, a closed cavity containing pressure air is formed between every two layers of the sidewall, the cavity body is in a diameter-variable cylindrical shape with two thicker ends and a thinner middle part, and a vent hole is arranged on each cavity, the spring is hollow and therefore good in top-to-bottom air penetrability, the inflation amount of the cavity is adjusted in real-time by means of inflation or deflation via the vent hole in order to adjust the hardness (elasticity) of the air pressure spring and to enhance the comfortable level and applicable scope; after the pressure air in the cavities is eliminated and the diameter-variable cylindrical air pressure spring is compressed, the spring takes up a small space and can be coiled to facilitate package, storage and transportation; and cavity columns may be independent, or may be formed in rows or in lines, and the cavities of the cavity columns may be either independent of or communicated with each other. | 05-29-2014 |
