Abstract
A resettable pressure bar module includes a pressure bar, a rotation element, and a resetting element. The pressure bar includes an outer tube, an upper sealing element, and a lower sealing element. The upper sealing element and the lower sealing element are disposed in the outer tube and respectively disposed on the opposite two sides of the outer tube. The rotation element is fixed to the outer tube and the lower sealing element through a fixing element. One side of the resetting element includes a first guiding slope and a second guiding slope. The pressure bar passes through the resetting element. The rotation element is configured to rotate to a normal position along the first guiding slope or the second guiding slope.
Claims5
A resettable pressure bar module comprising:
- a pressure bar including an outer tube, an upper sealing element and a lower sealing element, with the outer tube adapted to be fixed to a chair cushion and disposed in a supporting tube, wherein the upper sealing element and the lower sealing element are disposed in the outer tube and respectively disposed on opposite two sides of the outer tube, with the pressure bar further including a piston and a piston bar, with the piston disposed within the outer tube and located between the upper sealing element and the lower sealing element along a longitudinal axis of the outer tube, with the piston bar including a first end and a second end spaced from the first end along the longitudinal axis, with the first end of the piston bar passing through the lower sealing element and fixed to the piston in the outer tube, with the second end of the piston bar being outside of the outer tube and fixed to the supporting tube, wherein the outer tube is moveable relative to the piston bar along the longitudinal axis;
- a rotation element fixed to the outer tube and the lower sealing element through a fixing element, with the rotation element disposed in the supporting tube and outside the outer tube;
- and
- a resetting element disposed in and fixed to the supporting tube, one side of which including a first guiding slope and a second guiding slope, wherein the outer tube of the pressure bar passes through the resetting element, and the rotation element is configured to rotate to a normal position along the first guiding slope or the second guiding slope,
- wherein the resetting element includes a guiding element and a vibration reducing element, with the guiding element including the first guiding slope and the second guiding slope, with the vibration reducing element including a vibration reducing portion located between the first guiding slope and the second guiding slope, with the normal position located at the vibration reducing portion, wherein the guiding element includes a recess, and the vibration reducing element is inserted into the recess to connect to the guiding element.
