An object of the present invention is to provide a slant-adjusting unit which is convenient to adjust the slant of the flat plate supported by the legs and furniture having the unit.

and a slant-adjusting unit 200, comprising a first spherical plate 210, second spherical plate 220 having an inner curved surface in facing relation to an outer curved surface of the first spherical plate 210, and a third spherical plate 230 having an outer curved surface in facing relation to an inner curved surface of the first spherical plate 210, and furniture 1, comprising a flat plate 100, the slant-adjusting unit 200 connected to any position of the flat plate 100, a column portion 300, and connected to the slant-adjusting unit 200, and the flat plate 100 integrated with the first spherical plate 210 to adjust the slant at will.

A joint for furniture includes furniture piece that has a first hole that extends through a surface of the furniture piece and out the furniture piece, and that has a second hole with an opening in the furniture piece. A leg is fitted to the furniture piece. The leg has a hole. A curved tenon piece includes a head. The curved tenon piece is curved sufficiently to allow the curved tenon to enter the first hole through the surface of the furniture piece, to exit the first hole, to extend through the hole in the leg and to enter into the second hole so that the head leg is held snugly to the furniture piece by the curved tenon piece.

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.

A joint structure includes a first connecting unit, a second connecting unit, and a securing member. The first connecting unit has a distal end portion, a proximate end portion, and a connecting surface formed on the proximate end portion. The second connecting unit has a coupling surface and a connecting slot formed on the coupling surface. The securing member is configured to securely connect the first and second connecting units, so when the proximate end portion of the first connecting unit is inserted into the connecting slot of the second connecting unit, the securing member is configured to lock up the first and second connecting units. The joint structure is configured to prevent lateral rotational movement between the first and second connecting units and to reinforce the furniture structure having such joint structure, especially when an excessive load is applied to the distal end of the connecting unit.

The invention relates to a device and to a method for producing components which are to be used, for example in the field of furniture and components industry. These components can be for example, tables, chairs, cabinets, furniture fronts, frame elements or similar.

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 rack construction assembly for building a storage rack includes a plurality of bracket units. Each of the bracket units has a plurality of channels therein to insertably receive dimensional lumber. Thus, the dimensional lumber is arranged to form a rack for storing objects. Each of the channels corresponding to each of the bracket units is oriented at right angles with respect to each other. Thus, the dimensional lumber corresponding to each of the channels defines an X axis, a Y axis and a Z axis of the rack.
