Sept. 8, 1953 w. c. LUCAS CORNER FASTENER FOR CHAIRS Filed June 12, 1950 lung'- INVENTOR WALTER C. LUCAS BYZM'I 5 4% ATTORNEY Patented Sept. 8, 1953 CORNER FASTENER FOR CHAIRS Walter C.,Lucas,'Asheboro, N. 0. Application June 12, 1950, Serial No. 167,525 2 Claims. (Cl. 155-196) This invention relates to chairs for general use and the particular object of the invention is to provide a chair of sturdy and simple construction.

An important feature of the invention resides in locating all of the legs within the seat frame of the chair, and by extending the back legs upwardly, utilizing them as a support for the back of the chair.

An equally important feature of the invention is a chair construction wherein the legs are braced against the corners of the seat frame and secured to each adjacent side of the frame at the respective corners.

Another feature of the invention resides in supporting the seat by means of the seat frame, the legs, and corner braces for the seat frame.

A feature which produces a strong and simply built seat frame resides in joining the ends of the seat frame at the corners by mitered joints and connecting the mitered corner joints by an embedded fiat metal strip. Thereby is avoided the use of dowels, nails and similar devices formerly employed in chair manufacturing.

A further advantage of the invention resides in a chair having relatively few parts which may be easily assembled and, if necessary, easily repaired.

Referring to the drawings:

Figure 1 is a side view partly broken away;

Figure 2 is a front view;

Figure 3 is a rear view; and

Figure 4 is a, section on the line 4-4 of Figure 2 through the rear leg.

In Figure l the seat frame is indicated as a whole at I upon which is positioned the seat I I, the seat being supported by the frame and the front legs I2 and the rear legs I3.

The seat frame I2 consists of four pieces of wood, the ends of which are neatly connected as by a mitered joint I4 and are held together by the embedded fiat metal strip I5, as shown in Figure 4 which extends across the joint, as shown. At each corner of the frame I0 there is provided a brace I6, which, it will be noted, extends interiorly of the seat frame and is connected to the adjacent two sides thereof by countersunk screws I1. The seat is held in position in the usual manner by means of screws III which extend upwardly from the braces to engage the wooden base I9 of the seat. This wooden base is covered with any suitable type of upholstery 20 in the usual manner. Referring to Figure 1, it will be noted that the seat is supported by the front legs, as well as by the seat frame, and by the braces I6.

' Each leg fits neatly into a corner of-the chair, as shown in Figure 4, and is connected' to the adjacent side members of the seat frame III by means of the countersunk screws 2| and 22 which extend at right angles to each other. Thus, the legs are braced against the sides of the seat frame at the respective corners, as shown at 23, and connected to the adjacent sides, so that a sturdy construction is provided. This rigidity and strength is further enhanced by the provision of corner blocks I6, as shown in Figure 4 which are glued or otherwise secured to the adjacent side of the seat frame and a leg at each corner of the chair seat frame.

At the back of the chair, the rear legs l3 are extended upwardly, as shown at I3, and to their spaced upper ends is connected, by screws 24 or in any other suitable manner, the upholstered back of the chair 25. The seat II is cut away, as shown at 26 in Figures 1 and 3 just sufficient to allow the extended portions of the legs I3 to pass therethrough and form a neat appearing structure.

The rear legs adjacent the seat frame III are undercut to provide recesses, as at 21, on the two sides abutting the adjacent corner portions of the sides of the seat frame, as shown in Figures 1, 3 and 4, so as to receive these sides of the seat frame and support the same, as shown at 28. Also, the front legs are undercut to form ledges 29 on one side to support the opposite sides of the seat frame at the front portion of the seat.

By arranging all of the legs so that they are disposed within the seat frame, in the manner described, a chair having substantial rigidity is produced and, at the same time, a very comfortable and attractive article is obtained. In thi connection, and referring to Figure 4, it will be noted that the brace I6 can be arranged so as to have one side abut the adjacent corner of each leg, as shown at 30, which will impart additional strength to the chair.

By cutting away the seat II at the rear corners, as shown at 26, it is possible to utilize the legs I3 by reason of their integral extensions I3 to form the support for the back which will result in considerable saving of both labor and material, and, as indicated, will add rigidity to the chair.

A chair produced in accordance with this invention can be readily asembled since there are few parts and these can be replaced readily, if necessary, for purposes of repair.

I claim:

1. A chair having a seat frame, legs each di-' rectly connected to two adjacent sides of the frame and within the frame at the corners thereof, the rear legs extending upwardly through the frame to provide a support for a chair back, said rear legs at two sides thereof having undercut portions providing recesses to receive the adjacent sides of the seat frame at the corners, the front legs having undercut portions providing recesses to receive the sides of the seat frame at the front thereof, brace members extending across each of the corners of the seat frame and having one side thereof engaging a leg to impart rigidity to the chair, at least one corner block united to one side of each leg and the'adjacent side of the seat frame, a chair back secured to 5 the extensions of said rear legs, and a seat positioned on said frame and supported by said frame. by said legs, and by said braces, said seat cut away to permit the Ices to pass upwardly having the back corners extensions of the rear therethrough.

2. A chair according to claim 1 wherein the adjacent ends of said seat frame meet in mitered joints to form the corners and are connected by embedded metal strips extending across the corner joints.
