A mortise and tenon joint for furniture, includes a mortise piece and a tenon piece. The mortise piece includes a cut-out region. The cut-out region includes a surface. A mortise is located at the cut-out region. A tenon piece includes a tenon sized to fit within the mortise. The tenon piece has a surface that matches the surface of the cut-out region so that when the tenon is within the mortise, the tenon piece can be rotated into a first orientation so that the surface of the tenon piece is flush with the surface of the cut-out region, and the tenon piece can be rotated into a second orientation so that the surface of the tenon piece is not flush with the surface of the cut-out region.

Disclosed herein is a simple table usable in conjunction with PET bottles. The simple table includes: a table configured such that receiving depressions in which threads are formed on their inner circumferential surfaces are formed therein; and coupling parts configured such that threads corresponding to the threads of the receiving depressions are formed on the outer circumferential surfaces thereof and such that coupling holes in which threads corresponding threads on the outer circumferential surfaces of the mouth and neck portions of the PET bottles are formed on their inner circumferential surfaces are formed therein; wherein the coupling holes are formed to a depth larger than the heights of the mouth and neck portions of the PET bottles so that the heights of the PET bottles coupled to the table can be adjusted based on the insertion depths of the mouth and neck portions of the PET bottles.

A bedding or seating product comprises a connector assembly and a stabilizer assembly at each corner of the product for joining perpendicular first and second upholstered trusses. Each stabilizer assembly comprises a first bracket secured to the first truss, a second bracket secured to the second truss and a leg assembly comprising a leg and a threaded rod. One of the first and second brackets has a threaded boss and the other of the first and second brackets has an opening aligned with the threaded boss. The threaded rod extends through the aligned threaded boss and opening of the first and second brackets and the leg abuts the first and second trusses to assist supporting the product above the ground.

A table comprising a table base and a tabletop is disclosed. The table base comprises a top surface comprising a rotatable portion comprising one or more permanent magnets. The rotatable portion rotates independently from the table base. At least a portion of the tabletop comprises a ferromagnetic material. The tabletop further comprises a usable first side and a usable second side alternately mounted to the table base by an attractive force between the ferromagnetic material and the one or more permanent magnets. Rotation of the rotatable portion of the top surface, such that the one or more permanent magnets are oriented away from the ferromagnetic material, engages or disengages the attractive force.

A quick lock-release mechanism for assembling a table plate to table legs that includes a lower ring, a cap, two locking wings and a two springs. The lower ring includes a central hole and two opening pins. The cap includes a circumferential rim and two pins. The locking wings include an axial hole, a hole for receiving a tension screw and a sloping side. The springs and the locking wings are designed to be assembled onto the spring wings pins. The tension screws are designed to be screwed into the holes for receiving the tension screw. The springs push the locking wings toward the center of the mechanism so that the locking wings cover a part of the central hole and when rotating the cap relatively to the lower ring the spring wings pins exert force on the locking wings and push back the locking wings.

An apparatus may comprise a plate, an arm, and an arm fastener. The plate comprises: a plate edge, an arm mounting region, and surface mounting region(s). The surface mounting region(s) is configured to affix the plate to a surface with the plate edge facing a surface terminus of the surface. The arm comprises a leg mounting region. The arm fastener is configured to adjustably hold the arm to the arm mounting region with the leg mounting region extending beyond the plate edge.

A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.

An upholstered seating furniture frame (4) comprises a seat frame part (6) and at least a first leg part (8) connectable to the seat frame part (6). The seat frame part (6) comprises a seat frame structure (14, 16, 18, 20) which is at least partly made from hollow tubes. At least one of the seat frame part (6) and the first leg part (8) comprises a supporting device (72). The supporting device (72) is adapted to align and hold the first leg part (8) mounted to the seat frame part (6) in a self-standing intermediate assembly state. At least one of the seat frame part (6) and the first leg part (8) comprises at least portions of a final connecting device (76, 78, 80, 38, 104) adapted for final connection of the first leg part (8) to the seat frame part (6) for transforming the self-standing intermediate assembly state into a self-standing ready-to-use state.
