Abstract

A frame height adjusting mechanism is adapted for a frame including an inner pipe and an outer pipe sheathing on the inner pipe. A fixing hole is formed on one of the inner pipe and the outer pipe. A plurality of positioning holes is formed on the other one of the inner pipe and the outer pipe. The frame height adjusting mechanism includes a driving member which is slidably disposed on the inner pipe or the outer pipe where the fixing hole is formed and includes at least one first inclined surface, and at least one engaging member which is slidably disposed on the driving member and passing through the fixing hole to insert into one of the plurality of positioning holes. The at least one first inclined surface pushes the at least one engaging member to disengage from the corresponded positioning hole when the driving member slides upwardly.

First claim

What is claimed is:

1. A frame height adjusting mechanism adapted for a frame, the frame comprising a horizontal pipe, a cover installed on the horizontal pipe, an inner pipe and an outer pipe sheathing on the inner pipe and fixed on a lower end of the horizontal pipe, a sliding slot being sunk from a top surface of the horizontal pipe, a fixing hole being formed on a front side of a lower end of the outer pipe, a plurality of positioning holes being formed on a side of the inner pipe adjacent to the fixing hole along a vertical direction, and the frame height adjusting mechanism comprising:
a driving member slidably disposed on the outer pipe, the driving member comprising at least one first inclined surface, an upper end of the driving member passing through the horizontal pipe upwardly and being movable relative to the horizontal pipe along the vertical direction;
at least one engaging member slidably disposed on the driving member and passing through the fixing hole to insert into one of the plurality of positioning holes, the at least one first inclined surface pushing the at least one engaging member to disengage from the corresponded positioning hole when the driving member slides upwardly, the at least one engaging member and the at least one first inclined surface being disposed on a lower end of the driving member;
a linking member slidably disposed on the horizontal pipe along a longitudinal direction of the horizontal pipe, the linking member comprising at least one second inclined surface driven to push the driving member by the linking member, the linking member being slidably received in the sliding slot and covered by the cover;
a stopping portion upwardly protruding from an end of the linking member near a side of a lower end of the at least one second inclined surface; and
an abutting portion downwardly protruding from the cover and abutting against a side of the stopping portion toward the at least one second inclined surface.

2. The frame height adjusting mechanism of claim 1 , wherein an extending direction of the at least one second inclined surface and a sliding direction of the linking member are located in a same plane, and the frame height adjusting mechanism further comprises at least one first contacting portion disposed on the upper end of the driving member and abutting against the lower end of the at least one second inclined surface.

3. The frame height adjusting mechanism of claim 2 , wherein the driving member further comprises a rectangular portion, and the at least one first contacting portion is a column protruding from a side of the rectangular portion.

4. The frame height adjusting mechanism of claim 3 , wherein an avoiding slot is formed on the linking member and extends along the sliding direction of the linking member, the driving member passes through the linking member, the rectangular portion is slidably received in the avoiding slot, the linking member comprises two second inclined surfaces disposed on two sides of the avoiding slot, and the frame height adjusting mechanism comprises two first contacting portions respectively protruding from two sides of the rectangular portion.

5. The frame height adjusting mechanism of claim 3 , wherein a guiding slot is formed on the outer pipe along the vertical direction, and the rectangular portion is slidably received in the guiding slot.

6. The frame height adjusting mechanism of claim 1 , further comprising a first resilient member disposed between the cover and the linking member, and the first resilient member providing a first resilient force for pushing the driving member downwardly.

7. The frame height adjusting mechanism of claim 1 , wherein a circular hole is formed on the cover for allowing the driving member to pass through upwardly, and the circular hole penetrates the abutting portion.

8. The frame height adjusting mechanism of claim 1 , wherein the at least one first inclined surface obliquely extends away from a rear side of the outer pipe from top to bottom, the at least one engaging member comprises a second contacting portion, and the second contacting portion abuts against an upper end of the at least one first inclined surface when the at least one engaging member is inserted into one of the plurality of positioning holes.

9. The frame height adjusting mechanism of claim 8 , wherein a recess area is formed on a front side of the outer pipe, the fixing hole is formed on a bottom wall of the recess area, the driving member is located in the recess area, a long hole is formed on the lower end of the driving member and corresponded to the fixing hole, the long hole extends along the vertical direction, the at least one first inclined surface located at an outer periphery of the long hole protrudes from a side of the driving member away from the rear side of the outer pipe, the at least one engaging member is a pin of a rotating structure, and the second contacting portion protrudes from an outer periphery of the at least one engaging member.

10. The frame height adjusting mechanism of claim 9 , wherein a U-shaped portion protrudes from the side of the driving member away from the rear side of the outer pipe and encloses a lower portion of the long hole, and the at least one first inclined surface is formed on an upper end of each of two side walls of the U-shaped portion.

11. The frame height adjusting mechanism of claim 9 , wherein the frame further comprises a lower plug detachably inserted into the lower end of the outer pipe, the lower plug comprises a sliding portion slidably received in the recess portion, and a through hole is formed on the sliding portion and corresponded to the fixing hole.

12. The frame height adjusting mechanism of claim 11 , further comprising a second resilient member disposed between the lower plug and the at least one engaging member, the second resilient member providing a second resilient force for inserting the at least one engaging member into one of the plurality of positioning holes.

13. The frame height adjusting mechanism of claim 1 , further comprising an operating member and a connecting wire, the operating member being slidably disposed on the frame, an end of the connecting wire being fixed on the operating member, and the other end of the connecting wire extending along the horizontal pipe and being fixed on the linking member.

14. A frame comprising:
two bottom feet disposed oppositely;
two lower stands vertically fixed on the two bottom feet respectively;
two upper stands sheathing on the two lower stands respectively;
a bottom pipe disposed between the two bottom feet;
a horizontal pipe fixed between the two upper stands, a sliding slot being sunk from a top surface of the horizontal pipe;
a cover installed on the horizontal pipe;
an inner pipe fixed on the bottom pipe;
an outer pipe slidably sheathing on the inner pipe and fixed on a lower end of the horizontal pipe, a fixing hole being formed on a front side of a lower end of the outer pipe, a plurality of positioning holes being formed on a side of the inner pipe adjacent to the fixing hole along a vertical direction; and
a frame height adjusting mechanism comprising:
a driving member slidably disposed on the outer pipe, the driving member comprising at least one first inclined surface, an upper end of the driving member passing through the horizontal pipe upwardly and being movable relative to the horizontal pipe along the vertical direction;
at least one engaging member slidably disposed on the driving member and passing through the fixing hole to insert into one of the plurality of positioning holes, the at least one first inclined s
