A pedestal leg assembly includes a pedestal leg and floor base. The leg includes a plurality of teeth near the bottom end of the leg and a connecting bolt in a threaded engagement with the bottom end of the leg. The floor base includes a recessed portion having a slot in its bottom surface to receive the bolt and a release mechanism configured to pivot between a lock position and a release position. In lock position the release mechanism engages at least one of the teeth to prevent rotation of the pedestal leg in at least one direction. When pivoted into release position, the release mechanism is moved away from engagement with the teeth to allow rotation of the pedestal leg in both clockwise and counterclockwise directions. The pedestal leg assembly may include a powered connection to receive input power and/or a communication signal at the floor base and transfer the power and communication signals to a supported table top surface.

A multi-directionally engageable column combination structure comprising a column, a first hook body, and a second hook body. The column is in a straight cylindrical shape and has an outer circular surface and two end faces. A plurality of axial combination grooves are disposed at the outer circular surface, and the combination groove has an opening, a first catching groove and a second catching groove; a front end of the first hook body has a first hook portion, a rear end of the first hook portion has a first engaging portion, a front end of the first hook portion has a first hook pillar, a first hook edge is disposed at a front end of the first hook pillar, an abutting edge is disposed at a position that is on the first hook portion and corresponds to the outer circular surface of the column; a side of the first engaging portion has a first engaging surface, and a first combination hole is disposed on the first engaging surface; a front end of the second hook body has a second hook portion, a rear end of the second hook portion has a second engaging portion, a front end of the second hook portion has a second hook pillar, a second hook edge is disposed at a front end of the second hook pillar, a side of the second engaging portion has a second engaging surface attached against the first engaging surface, and a second combination hole is disposed, the first and second hook edges of the first and second hook bodies hook the first and second catching grooves respectively, and then engaging elements are inserted into the first and second combination holes for combination. Thus, better assembly convenience and stability are achieved in the present application.

A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

Disclosed herein is a detachable interlocking system for securing at least two articles together, the interlocking system including: a first interfacing portion; ii. a second interfacing portion; iii. the first and second interfacing portions being in complementary arrangement configured to engage with one another in a first engaged position and are moveable to a second interlocked position; iv. locking means to interlock the first and second interfacing portions together; v. reciprocating means to receive and accommodate the locking means; wherein movement from the first engaged position to the second interlocked position engages the locking means to interlock the first and second interfacing portions together.

The present disclosure provides systems and methods for assembling a device while maintaining the aesthetic appearance and structural integrity of a visible surface of the device. In one or more implementations of the invention, a system includes a first assembly piece with an assembly region that comprises an opening defined by first and second connecting elements. The system further includes a second assembly piece and a fastening assembly, where a portion of the second assembly piece is shaped to fit within the assembly region opening and the fastening assembly spans the first and second connecting elements to secure the first assembly piece to the second assembly piece, and tightening of the fastening assembly causes the second connecting element to deform, pressing a surface of the second assembly piece against an adjacent surface of the first connecting element and retaining a substantially even visible surface of the device.

The leg includes a plurality of teeth near the bottom end of the leg and a connecting bolt in a threaded engagement with the bottom end of the leg. The floor base includes a recessed portion having a slot in its bottom surface to receive the bolt and a release mechanism configured to pivot between a lock position and a release position. In lock position the release mechanism engages at least one of the teeth to prevent rotation of the pedestal leg in at least one direction. When pivoted into release position, the release mechanism is moved away from engagement with the teeth to allow rotation of the pedestal leg in both clockwise and counterclockwise directions. The pedestal leg assembly may include a powered connection to receive input power and/or a communication signal at the floor base and transfer the power and communication signals to a supported table top surface.

Provided is a coupling system comprises a first tubular member with a top end and a second tubular member with a bottom end, defining together a longitudinal axis. One of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending socket portion. The other one of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending plug portion for coaxial snug receipt within the socket portion. Each tubular socket portion and the plug portion is configured with a lock opening intersecting the longitudinal axis. The coupling system includes a locking plug configured for locking engagement of the lock openings while in register with one another, thereby preventing axial or rotary displacement of the first tubular member and the second tubular member.
