Abstract
Disclosed are pivoting mechanisms, sliding mechanisms, frames and tables. A pivoting mechanism includes a first coupling piece, a second coupling piece and a rod. The first and second coupling pieces are pivotally coupled with each other. The rod is operated by gravity to automatically lock or unlock the first and second coupling pieces. A sliding mechanism generally includes a slider and a locking member. The slider includes a sleeve to be slidably coupled with a bar. The locking member includes a restriction piece, operated by an elastic piece to be disposed inside of the bar, to automatically lock the sleeve at a certain position of the bar.
Claims20
A sliding mechanism comprising:
- a slider comprising:
- a sleeve configured to be slidably coupled with a first bar and pivotally coupled with one or more second bars, wherein at least a portion of the first bar is hollow and a first restriction hole is formed at a side wall of the hollow portion of the first bar;
- a second restriction hole formed at the sleeve and corresponding to the first restriction hole formed at the first bar;
- and
- a push button coupled with the sleeve and insertable into the second restriction hole;
- and
- a locking member comprising:
- an elastic piece configured to be disposed in the hollow portion of the first bar and adjacent to the first restriction hole formed at the first bar;
- and
- a restriction piece formed or coupled with the elastic piece;
- wherein when the second restriction hole formed at the sleeve is aligned with the first restriction hole formed at the first bar, the elastic piece pushes the restriction piece outwardly into the first restriction hole formed at the first bar and the second restriction hole formed at the sleeve, thereby restricting the sleeve from moving along the first bar;
- wherein the push button is configured to push the restriction piece inwardly to disengage the restriction piece from the second restriction hole formed at the sleeve, thereby allowing the sleeve to move along the first bar.
