Application November 18, 1946, Serial N 0. 710,422
My present invention relates to an improved knockdown chair of the type comprising a minimum of parts so arranged that the assembly or disassembly may be accomplished in a very short time, and at the same time, the chair or table made according to my invention will be when locked in position strong and durable. Due to the simplicity of the parts, the chair or table may be manufactured at low cost, and will fill a need in collapsible furniture for indoor or outdoor use.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.
In the drawings:
Figure 1 is a side elevational view of the assembled chair according to my invention.
Figure 2 is a front elevational view thereof.
Figure 3 is a top plan view of the chair.
Figure 4 is an enlarged detail view of the front locking dowel for the seat; and Figure 5 is a sectional view thereof at line 5-5 of Figure 4.
Figures 6, 7, 8, 9, and are plan views of the various elements of the chair.
Figure 11 is an end elevational view of the structure of my invention as embodied in a knockdown table.
Figure 12 is a side elevational view thereof.
Figure 13 is a perspective View of the dowel and dovetail slot locking means for the table top.
Figure 14 is a bottom plan view of the assembled table.
Figure 15 is a plan view of the side piece.
Figure 16 is a plan View of the leg elements.
Figure 17 is a partial bottom plan view of the table top showing the locking slot; and
Figure 18 is a Vertical sectional View of the table top through the slot of Figure 17.
Referring now to the drawings wherein like characters indicate like parts I have illustrated the present embodiment of the structure of my invention as comprising the sides 2 having legs 4 and 6 with the back supports 8, and provided with vertical notches 12 over the front legs 4, horizontal slots [4 over the rear legs 6, and vertical slots 16 at the upper ends of the back supports 8.
A front brace member 18 is formed with notches 20 for co-action with the notches l2, and the upper edge of the brace is dovetailed as at 22.
The seat 24 is provided with rear notches 2B for co-action with the notches it of the sides and 2 the slot 23 near the rear edge of the seat is locked as hereinafter stated, while the dowel 36 under the front part of the seat engages the dovetail 22 of the brace.
The T-back 32 is formed with notches 34 in the under edge of the cross member for co-action with the notches it of the back supports 8, and the base 35 is fitted for insertion through the slot 28 of the seat. A vertical slot in the base of the back as at 38 is positioned at a point in the base 36 so that it will be below the seat when the base is inserted through the slot 23, and the wedge 48 is passed through the slot 38 to frictionally engage the under side of the seat and thus retain the wedge in driven position,
All of the five parts hereinbefore described may be of plywood or other suitable material, and may be ornamented or dadoed as desired, and it will be apparent that when the parts are assembled as stated and as shown in the drawings, the chair parts will be locked securely in position. No tools are required either in the assembly or disassembly, as any suitable object may be employed to drive home the wedge.
A further exemplification of the structure of my invention is set forth in Figures 11 through 19 of the drawings wherein the invention is embodied in a knockdown table.
This embodiment comprises the legs 42 and 44 connected by member 46 and having upper notches 48, the dowels 59 in the upper edge of the connecter. The sides 52 are notched at 54 for co-action with the notches 48 and dowels 56 are positioned central of the upper edge of these side members,
The table top 58 is provided with dovetailed slots 6|] drilled at 52 for the entrance of the dowels, and when the legs and sides have been assembled and interlocked, the top is placed thereon with the drilled openings to the slots aligned with the dowels, and then a slight movement of the top will seat the dowels in the dovetailed slots. Disassembly follows a reverse procedure.
From the above description of the construction and manner of assembly it will be apparent that the chair and table incorporating the structure of my invention may be assembled with facility and ease, and the disassembled elements may be packed in a relatively small package for carrying or storage.
No nails, screws, glue or other matter is required other than the interlocking slots and notches of the various elements, and in the case of the chair, the wedge is the key to the locking 3 of the assembly, while in the case of the table, the dowels and the dovetailed slots provide the locking means.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
A knockdown chair comprising notched leg and back support sections, a notched seat engaging the lower portion of th back support sections and resting on the top of the leg sections, a front brace interlocked with the leg sections and having an upper dovetailed notch, a fan shaped dowel on the seat engaging the latter notch, a back having notches engaging the back support sections and a lower tongue extending through the rear of the seat and formed with a slot therethrough, and a wedge through th slot engaging the under side of the seat and comprising the key to the assembled chair.
EDWARD F. CENIS.
