CHAIR CONSTRUCTION May 2, 1967 Filed May 17, 1965 2 Sheets-Sheet 2 United States Patent O 3,317,242 CHAIR CONSTRUCTION Donald L. Moore and Orville E. Snyder, Gallatin, Tenn., assignors to Hamilton Cosco, Inc., Columbus, Ind., a corporation of Indiana Filed May 17, 1965, Ser. No. 456,276 4 Claims. (Cl. 297-353) This invention relates to a chair construction, and more particularly to a chair back rest.

It is an object of this invention to provide a chair having a back rest mounted thereon which can be easily assembled for shipment in a compact knocked-down condition, which will be of attractive appearance, and which will prove sturdy and durable in use.

In accordance with one form of the invention, there is provided a chair having a seat supported on a suitable ground-engaging base. A pair of back supports extend upwardly above the seat at the rear thereof for supporting a back rest in an elevated position above said seat. Spacers are interposed between the back rest and the back supports, and fastening means exten-d through s-aid back supports and spacers for reception in the back rest for mounting said back rest on said supports. A channeled cover extends over the upper ends of the back supports to hide their connections to the back rest. A plate is mounted on said cover and is provided with a pair of guides receivable on the back supports. Said plate is provided with -a finger adjacent its lower end adapted to receive fastening means for interconnecting said cover and back rest.

Other objects and features of the invention will become apparent from the more detailed description which follows and from the accompanying drawings, in wihch:

FIG. 1 is a side elevation of a chair embodying the invention;

PIG. 2 is a rear elevation of the chair back rest with portions thereof being broken away;

FIG. 3 is an enlarged vertical section taken on the line 3-3 of FIG. 2; and

FIG. 4 is an enlarged horizontal section taken on the line 4 -4 of FIG. 2.

As shown in the drawings, a seat is mounted ron any suitable ground-engaging base for supporting said seat in an elevated position above the ground. If desired, the seat can be carried on side frames 14 having upwardly projecting membersv 15 adapted to support arm rests 16.

A pair of laterally spaced, generally L-shaped back supports 17 are connected at their lower ends to the seat 10 or base 12 and project upwardly from the rear edge of the seat for supporting a back rest 18. Conveniently said back rest is formed from a wooden panel 19 having a cushioned cover 20 extending thereover. A tubular spacer 22 having a width less than the widths of the back supports is interposed between each of the supports 17 and the back rest 18. Screws 24 extend through the back supports 17 and spacers 22 for reception in tapped staples 25 in the back rest for xedly mounting the back rest on said back supports.

In order to hide the interconnection between the back support and back rest to thus enhance the appearance of the chair, a channeled cover 27 is disposed over the upper ends of the back supports and spacers. As shown, said cover comprises a web 28 disposed against the rear faces of the back supports 17 and interconnecting a pair of forwardly projecting legs 29. Desirably, the upper end of the web 28 is bent forwardly to form a top cover wall 30. A mounting plate 32 is mounted on the inner face of the cover web 28. Said plate has vertically extending L- shaped guides 34 at its lateral ends which are receivable on the front and adjacent side faces of the back supports 3 ,3 17,242 Patented May 2, 1967 17 for thus retaining the cover 27 in a xed later-al position with respect to said back supports. The lower end of the plate 32 comprises a forwardly projecting nger 35 adapted to be disposed in abutting engagement with the rear face of the back rest 18. Said finger is provided with an opening 36 for the reception of a screw 38 for Iixedly mounting the cover on the back rest.

In -assembling the back rest on the back supports, the screws 24 are drawn up in the staples 2S with the spacers 22 being interposed between said back supports and back rest. 'l`=he cover plate 27 is then slid downwardly over the back supports with the guides 34 sliding against the front and side faces of said back supports. With the cover in the desired position of vertical adjustment on the back supports, the screw 38 is tightened as by inserting a screwdriver through the open lower end of the cover. Thus, with the back rest fully assembled, all of the interconnections between said back rest and the back supports will be hidden from View and will not detract from' the appearance of the chai-r.

We claim:

l1. In a ch-air construction, a back rest, a pair of back supports connected to the back rest for supporting said back rest in an elevated position above a chair seat, a cover having an open lower end and extending over the upper portion of said back supports, and a plate carried within said cover and mounted on the inner face thereof having a pair of guides slidably received on said back supports, said plate having an offset finger at its lower en-d adapted to be connected to said back rest for mounting the cover thereon.

2. In a chair construction, a back rest, a pair of laterally spaced back supports for supporting said back rest in an elevated position above a chair seat, spacing means interposed between said back rest and back supports, fastening means extending through said spacing means and interconnecting said back rest and back supports, a channeled cover extending over said spacing means and the upper portion of said back supports with said spacing means disposed within the extent of said cover, and a plate carried within the cover and mounted on the inner face thereof havinga pair of gui-des carried on the adjacent portions of said back supports, said plate having its lower end offset against said back rest and adapted to be connected thereto.

3. In a chair construction, a back rest, a pair of laterally spaced back supports for supporting said back rest in an elevated position above a chair seat, spacing means interposed between said back rest and back supports, fastening means extending through said spacing means and interconnecting said back rest and back supports, a channeled cover extending over said spacing means and the upper portion of said back supports, and -a plate mounted on the inner face of said cover and having a pair of guides carried on the adjacent portions of said back supports with the upper portions of said back supports being interposed between said guides and the inner face of said cover, said plate having its lower end offset against said back rest and adapted to be connected thereto.
