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.
Claims9
A pivoting mechanism comprising:
- a first coupling piece configured to be fixed at a proximal end of a first bar, wherein the first coupling piece comprises a first slot elongated in a first direction;
- a second coupling piece configured to be fixed at a proximal end of a second bar, wherein the second coupling piece comprises a second slot, wherein the second slot has a closed bottom and an open top, and wherein the second slot has a length in the first direction that is shorter than the first slot of the first coupling piece in the first direction;
- a third coupling piece comprising a third slot having a closed bottom and a closed top, wherein the third slot is elongated in the first direction;
- a first rod disposed, cross-sectional-wise, in the third slot of the third coupling piece and movable along the third slot of the third coupling piece, wherein the first and second coupling pieces are pivotally coupled with each other by the first rod;
- and
- a second rod integrally formed or coupled with a top portion of the third coupling piece, the second rod disposed, cross-sectional-wise, in the first slot of the first coupling piece and movable along the first slot of the first coupling piece;
- wherein when the first and second coupling pieces are aligned with each other and the open top of the second slot of the second coupling piece faces downwardly, the third coupling piece together with the second rod moves by gravity to a first position where the second rod is disposed outside of the second slot of the second coupling piece, thereby allowing the first and second coupling pieces to rotate with respect to each other around the first rod;
- and
- wherein when the first and second coupling pieces are aligned with each other and the open top of the second slot of the second coupling piece faces upwardly, the third coupling piece together with the second rod moves by gravity to a second position where the second rod is disposed in the second slot of the second coupling piece, thereby restricting the first and second coupling pieces from rotating with respect to each other around the first rod.
