Abstract
Disclosed are adjustable supports and frames. An adjustable support includes an inner bar, an outer bar and a locking/unlocking mechanism for controlling the relative movement of the inner and outer bars. The locking/unlocking mechanism includes a casing pivotally connected with the outer bar, a pin coupled with the casing, and an elastic member to engage the pin with the inner and outer bars.
Claims19
An adjustable support comprising:
- an outer tubular bar comprising a first restriction slot formed on a side wall of the outer tubular bar at a first side of the tubular bar;
- an inner bar disposed at least partially inside the outer tubular bar and selectively movable along a length direction of the outer tubular bar, the inner bar comprising a second restriction slot formed at a first side of the inner bar corresponding to the first restriction slot of the outer tubular bar;
- and
- a locking/unlocking mechanism disposed outside of the outer tubular bar, and configured to control movement of the inner bar with respect to the outer tubular bar, the locking/unlocking mechanism comprising:
- a casing comprising a first portion, a second portion and an intermediate portion between the first and second portions, wherein the intermediate portion is pivotally connected with the outer tubular bar such that the first and second portions of the casing are rotatable with respect to the outer tubular bar;
- a locking pin integrally formed or coupled with the first portion of the casing and disposed at a position corresponding to the first restriction slot of the outer tubular bar;
- and
- an elastic member coupled with the second portion of the casing, the elastic member having a first end abutting the second portion of the casing and a second end abutting the side wall of the outer tubular bar, wherein when the second restriction slot of the inner bar aligns with the first restriction slot of the outer tubular bar, the elastic member pushes at least a portion of the locking pin into the second restriction slot of the inner bar, thereby restricting the inner bar from moving along the length direction of the outer tubular bar.

- an inner bar disposed at least partially inside the outer tubular bar and selectively movable along a length direction of the outer tubular bar, the inner bar comprising a second restriction slot formed at a first side of the inner bar corresponding to the first restriction slot of the outer tubular bar;
- a locking/unlocking mechanism disposed outside of the outer tubular bar, and configured to control movement of the inner bar with respect to the outer tubular bar, the locking/unlocking mechanism comprising:
- a casing comprising a first portion, a second portion and an intermediate portion between the first and second portions, wherein the intermediate portion is pivotally connected with the outer tubular bar;
- a locking pin integrally formed or coupled with the first portion of the casing and disposed at a position corresponding to the first restriction slot of the outer tubular bar;
- and
- an elastic member coupled with the second portion of the casing, the elastic member having a first end abutting the second portion of the casing and a second end abutting the side wall of the outer tubular bar, wherein when the second restriction slot of the inner bar aligns with the first restriction slot of the outer tubular bar, the elastic member pushes at least a portion of the locking pin into the second restriction slot of the inner bar, thereby restricting the inner bar from moving along the length direction of the outer tubular bar;
- and
- a clip comprising a mounting pin at each of first and second free end portions thereof, wherein
- the intermediate portion of the casing comprises a first installation hole at each of first and second sides of the casing;
- the outer tubular bar comprises a second installation hole at each of second and third sides of the outer tubular bar;
- and
- the mounting pin has a first portion received in the first installation hole of the casing and a second portion received in the second installation of the outer tubular bar, thereby pivotally coupling the casing with the outer tubular bar.
