A chair (1) wherein the back rest (10) comprises two elongated connection members (11a, 11b) each provided with a hole (12a) extending along a crossing direction (T). The respective leg (20a, 20b) is provided with a first bore (21a) extending along a longitudinal direction (L) and a second bore (22a) extending along the crossing direction (T), connecting with the first bore (21a). The first bore (21a) is configured to receive a portion of the elongated connection member (11a). The corner pieces (31a, 31a′) are provided with a through-going hole (32a) being configured to be in register with the hole (12a) of the elongated member (11a) and the second bore (22a) of the leg (20a, 20b). The chair (1) further comprises a first and a second fastening arrangement (40) extending through the through-going hole (32a) and through the second bore (22a) into the hole (12a) of the elongated connection member (11a) to interconnect the back rest (10), the legs (20a, 20b) and the corner pieces (31a, 31b, 31a′). The disclosure also relates to a kit of parts configured to be assembled into a chair.

A bench including a first support, a second support, a seat, and one or more protective metal plates. The seat extends between the supports. The metal plates extend above the seat or below the seat, or both, and provide at least NIJ Level IIA, preferably Level IV, ballistic protection. The metal plates are attached to the bench, partially or completely, via one or more reversible toolless connections such as a slotted hole and headed stud. The bench can be assembled and disassembled in the field by unskilled labor with few or no tools required.

A plate connecting assembly according to an embodiment includes a first frame, with an upper portion and a lower portion of the first frame making a predetermined angle with each other, and a second frame having a first support portion facing the upper portion and a second support portion facing the lower portion. In the plate connecting assembly, a first fixation-subject object is fixed between the upper portion and the first support portion, a second fixation-subject is fixed between the lower portion and the second support portion, and thus the first and second fixation-subject objects are fixed in such a manner that an angle therebetween is the same as an angle that the upper portion and the lower portion make with each other.

A whiteboard includes a whiteboard support and a board body, the whiteboard support includes two support rods arranged in parallel with each other, and each of them is formed by rigidly connecting the first tube body and the second tube body, can be detached one by one, and then stored. Compared with the one-piece support rod of the conventional whiteboard, the whiteboard according to the present embodiment greatly reduces the occupied area and reduces the difficulty in transportation, and the transportation cost for the enterprise. Meanwhile, by providing at least two insertion slots at different heights on the side of the support rod facing the board body, the board body of the whiteboard can be adjusted in height so as to adapt to use of people of different heights.

A modular cabinet assembly has at least a first sub-cabinet and a second sub-cabinet. Each sub-cabinet includes a back board having at least two separate back board pieces that are pivotably connected to each other, a left side board pivotably connected to one of the at least two back board pieces, and a right side board pivotably connected to another of the at least two back board pieces. At least one shelf board having opposite ends is removably connected to the left side board and the right side board of either the first sub-cabinet or the second sub-cabinet. A first end board is connected to either an upper end of the first sub-cabinet or a lower end of the second sub-cabinet. A first connector removably connects the left side boards of the first and second sub-cabinets, and a second connector removably connects the right side boards of the first and second sub-cabinets.

An oval-shaped T-nut that is received within an oval receiver machined into the upholstered panel to be secured to a chair frame is provided. The oval shape of the T-nut prevents the oval-shaped T-nut from rotating when a screw is driven into the T-nut. Further, this eliminates the necessity of stapling the traditional plastic T-nut to the chair panel, thus saving time and money associated with the manufacture of an upholstered metal frame chair. In addition to the oval-shaped T-nut described herein, a novel U-shaped screw catch is also provided which cooperates with a barbed nylon or plastic push rivet to secure the upholstered chair panels to one another. Further, a method for connecting upholstered seat back panels to the tabs positioned on the back frame of a chair, utilizing the T-nut and the screw catch is disclosed.
