A foldable leg assembly for use with self-leveling platforms, tables, and devices that includes at least one rotatable bracket assembly having a first section with an upper portion and a lower portion, wherein a curved channel is formed in the upper portion and wherein a stem and flange receiving region is formed in the lower portion; and a second section adapted to be connected to the first section and having an upper portion and a lower portion, wherein a curved channel is formed in the upper portion and wherein a stem and flange receiving region is formed in the lower portion; and at least one support device having a pivot device that is adapted to pivotally and rotationally engage the stem and flange receiving regions of the at least one rotatable bracket assembly, wherein the pivot device further includes a stem; a flange positioned on top of the stem; and a leg receiving portion.

An example folding table with simultaneously extending legs includes a table top structure. The example table also includes a plurality of table legs to support the table top structure. Each of the table legs part of a spherical four bar linkage. The example table also includes a plurality of driver links for the plurality of table legs. The driver links each part of a single driver component with a pivot at a center of the table top structure. The example table also includes a rotating coupler for on each end of the driver links. When one of the table legs is folded and unfolded, the other table legs move simultaneously in a first direction to open and in a second direction to retract.

A foldable frame with enhanced stability includes a mounting assembly, a first leg assembly and a second leg assembly. Each of the first and second leg assemblies are pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position. Each of the first and second leg assemblies includes a substantially straight first leg and a substantially straight second leg. The first and second legs are slanted outwardly to increase the supporting area and thus enhance the stability of the foldable frame and stability of other structures supported by the foldable frame.

A locking mechanism for a sliding rod having two spherical heads comprises the sliding rod, a sliding seat, and a locking device. The sliding seat is slidably mounted on the sliding rod along a length direction of the sliding rod. The locking device comprises the two spherical heads, one or more elastic members, and a button. The sliding seat comprises two buckle holes configured to correspond to the two spherical heads. The button is mounted at a position of the sliding seat corresponding to the two buckle holes. The two spherical heads are configured to be locked to the two buckle holes to inhibit sliding movement of the sliding seat, and the button is configured to act on the two spherical heads to drive the two spherical heads to exit from the two buckle holes to release the sliding seat from being inhibited from movement.

A foldable table includes a table tops and legs mounted for movement relative to the table top.

A multi-size folding table with a stable structure is provided. A table board includes a middle table board and two side table boards. Two ends of the middle table board are respectively pivotally connected to the two side table boards. The two side table boards are configured to be rotated to achieve unfolding and folding thereof. A bottom surface of the table board is correspondingly disposed with guiding members. The guiding members are respectively connected to four table leg assemblies. The four table leg assemblies are configured to reciprocate. Each of the four table leg assemblies includes a supporting leg for supporting the table board. When the two side table boards are in an unfolded position, the supporting legs are located below the two side table boards. When the two side table boards are in a folded position, the supporting legs are located below the middle table board.

A locking mechanism for a sliding rod having two spherical heads comprises the sliding rod, a sliding seat, and a locking device. The sliding seat is slidably mounted on the sliding rod along a length direction of the sliding rod. The locking device comprises the two spherical heads, one or more elastic members, and a button. The sliding seat comprises two buckle holes configured to correspond to the two spherical heads. The button is mounted at a position of the sliding seat corresponding to the two buckle holes. The two spherical heads are configured to be locked to the two buckle holes to inhibit sliding movement of the sliding seat, and the button is configured to act on the two spherical heads to drive the two spherical heads to exit from the two buckle holes to release the sliding seat from being inhibited from movement.
