Abstract
Claims
1. A shock-absorbing device suitable for installation between a chair post and a seat, comprising: a support rod unit suitable for being disposed at the top of the chair post; a lower support unit swayably connected to the support rod unit; an upper support unit suitable for being disposed at the bottom of the seat and spaced above the lower support unit; a front shock-absorbing unit including a floating block swayably connected between the front side of the lower support unit and the front side of the upper support unit, and a shock-absorbing body disposed between the floating block and the upper support unit; and a rear shock-absorbing unit including an elastic member elastically connected between the rear side of the lower support unit and the rear side of the upper support unit.
2. The shock absorption device as described in claim 1, wherein, The upper support unit includes an extension block located on the front side, the floating block of the front damping unit is located in front of the extension block and forms an angle with the extension block, and the damping body is located between the floating block and the extension block.
3. The shock absorption device as described in claim 2, wherein, The extension block has an upper end and a lower end below the upper end. The floating block has a lower pivot corresponding to the lower end and an upper pivot extending forward and upward from the lower pivot and spaced in front of the upper end. The front damping unit also includes a rear pivot pivotally connected to the lower pivot and the lower end, and two front pivots located in front of the rear pivot and pivotally connected to the upper pivot and the lower support unit. The floating block and the extension block can swing relative to each other about the rear pivot, and the floating block and the lower support unit can swing relative to each other about the front pivots. When the floating block and the extension block are clamped together, the damping body is clamped and damped.
4. The shock absorption device as described in claim 3, wherein, The front damping unit also includes a connector extending longitudinally and connecting the upper pivot and the upper end, the connector passing through the damping body to limit the damping body between the upper pivot and the upper end.
5. The shock absorption device as described in claim 4, wherein, The front shock absorber unit also includes a buffer member disposed on the front side of the upper pivot. The connector has a rod head located on the front side of the buffer member, a rod body extending rearward from the rod head and passing through the buffer member, the upper pivot and the shock absorber, and a rod tail formed at the rear end of the rod body and locked to the upper end.
6. The shock-absorbing device as described in any one of claims 2 to 5, wherein, The support rod unit includes a support member mounted on the top of the chair rod. The support member has a lower support portion spaced behind the extension block. The lower support unit includes two rocker arms located on the left and right sides of the support member and pivotally connected to the floating block at their front ends, a shaft assembly rotatably passing through the lower support portion and connected between the rocker arms, and a main support shaft mounted on the shaft assembly and connected to the rocker arms. The rocker arms are swaying relative to the support member with the shaft assembly as the center.
7. The shock absorption device as described in claim 6, wherein, The support member also has an upper support above and behind the lower support. The support rod unit also includes an upper pivot extending laterally and rotatably through the upper support. The lower support unit also includes a lower pivot located behind the main support shaft and rotatably pivotally connected between the rocker arms, and a connecting rod pivotally connected between the lower pivot and the upper pivot.
8. The shock absorption device as described in claim 7, wherein, The lower support unit also includes a lower top block located behind the lower pivot and rotatably pivotally connected between the rocker arms. The upper support unit also includes an upper top block located on the rear side and spaced above the lower top block. The rear shock absorber unit also includes a connecting member passing through the elastic member and connecting the lower top block and the upper top block.
9. The shock-absorbing device as claimed in claim 8, wherein, The rear shock absorber also includes a limiting body placed between the upper and lower blocks of the connector.
10. The shock-absorbing device as claimed in claim 8, wherein the seat includes a seat cushion and a seat arch disposed at the bottom of the seat cushion, the seat arch having two bilaterally symmetrical mounting sections spaced apart below the seat cushion, wherein, The upper support unit also includes two support frames spaced above the rocker arms and respectively supporting the mounting sections, two top pressing blocks that press the mounting sections against the support frames, and two fixing members that fix the top pressing blocks to the support frames. The support frames are integrally connected between the left and right sides of the extension block and the left and right sides of the upper top block.
