My invention relates to improvement in furniture construction.

Some of the more important advantages of the device, which is the subject of my invention are: (1) My invention provides means for assembling chairs and other furniture items quickly from their component parts. (2) Furniture items embodying my invention can be quickly dismantled for shipment or storage thus greatly reducing shipping and storage costs. (3) Furniture items embodying my invention can be manufactured readily from plastic materials and plywood. (4) And, furniture items embodying my invention are strong, sturdy, and economical in construction.

One form of the invention is illustrated in the accompanying drawing, in which:

Figure 1 is a side View of a chair constructed in a manner embodying my invention.

Figure 2 is an enlarged sectional view of Fig. 1 taken through 2-2 to show in detail the single connecting means which is an important feature of my invention.

Figure 3 is a View of the back and sides of the chair together with a sectional view of the seat and part of the stand to show the relation of these various pieces to each other.

Figure 4 is an enlarged sectional view of Fig. 3 taken through 4-4 to show in detail additional important interlocking features of my invention.

Figure 5 is a collective detail perspective view of the chair showing the parts in position to be assembled.

In describing my invention in greater detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views.

Referring to the drawings, the chair, which is of a knock-down type, comprises a base or pedestal formed from interengaged member 5 and 6, which base supports a removable back member I and side members 8 and 9 interengaging with the upper end of the back member 1, and detachably anchored at their lower ends to the seat II] at opposite sides thereof. The lower ends of the side members are held in anchored relation by removable pins II and I2, and the whole assembly is locked together in chair form by a single bolt [3 extending downwardly through the seat and through a washer l4 held in the upper end of the pedestal, and with which a nut l5, on the bolt, cooperates for rigidly holding the parts together.

The lower ends of the arms 8 and 9 extend downwardly through openings I6 and I! in opposite sides of the seat I0 and terminate below 4 Claims. (Cl. 155134) the seat. The lower ends of the arms 8 and 9 are provided with spaced apertures for the reception of transverse removable pins II and I2, hence it will be seen that the lower ends of the arms are rigidly anchored to the rear portion of the seat at opposite sides thereof, hence will rigidly support the upper end of the back I. The rear side of seat It] is recessed as shown in Figure 5 to form opposite shoulders 18 and IQ for the reception of the lower end of the back I and the notches (a in opposite sides of the lower end of the back, therefore it will be seen there is a positive detachable interlocking of the lower end of the back and rear of the seat. The upper end of the back I is provided with recesses 20 and 2| for the reception of the upper bifurcated ends 22 and 23 of the arms 8 and 9. Pins H and 12 pass through the spaced apertures 24 and 25 in the portions of the side members 8 and 9 projecting below the seat It), as clearly shown in Figure 1. Extending in opposite directions from the center of the under side of the seat ID are channels 26, and extending in cross relation thereto and in a direction from the front to the rear of the under side of the seat are channels 21 for the reception of the upper edges of the crossed interengaged pedestal members 5 and. 6. The pedestal member 5, which is in vertical longitudinal relation in the structure, is provided with a rearwardly elongated arm 210. having spaced notches 28 and 29 therein, and which notches are in alinement with the apertures 2d and 25 of side members 8 and 9, so that when the locking pins II and [2 are placed in position, or inserted from one side of the structure to the other, they will be received in the notches 28 and 29. Pins H and I2 are preferably provided with notches 38 and 3| in their under sides adapted to spring into interengagement with the bottom of the notches 28 and 29 for preventing easy longitudinal displacement of the pins.

Substantially centrally of the seat I8, an aperture 32 is provided for the reception of the bolt l3. Bolt l3 extends downwardly into the upper end of the pedestal and terminates below the entrance passage 33 in the upper end of the pedestal and below the inwardly extending arms 34, 35, 36 and 31 of the crossed pedestal members. Disposed on the bolt 13 is the washer M, which washer engages the under sides of the arms 34 to 3'! inclusive, and the washer is held in close binding engagement with the under side of said arms by the nut [5. It will be seen that when the nut I5 is tightened the seat In is securely clamped on the upper edges of the crossed members 5 and 6, and said upper edges are forced into interengagement with the seat and into the channels in the under side of the seat. The outer end of the elongated arm 21a terminates in an upwardly extending arm 29, which arm engages the rear lower side of the back 1, after the rear end of the arm 2| is in the recess 40 in the lower end of the back, hence it will be seen that the lower end of the back is securely locked between the shoulders l8 and [9 against outward movement. It will be noted that the upper side of the rearwardly extending arm 21a, adjacent the member 39, engages the upper end of the recess 40.

From the above it will be seen that a knockdown chair is provided which is simple in con struction, and held together by a single bolt and two locking pins. It will also be seen that the device can be cheaply manufactured and sold.
