Definitions
- a stacking type of chair has become very popular and common.
- Such a stacking chair is ordinarily designed to be stacked one upon another with a large number of chairs in a single stack, but superimposed close to each other so that a minimum of space is employed.
- a handle attached to the chair is also employed. It is one of the objects of this invention to provide a handle construction for such a chair which blends into the harmony of the chair construction and is recessed so that it is relatively protected from physical abuse to which the chairs are ordinarily subject.
- Another important problem with stacking chairs is that the stacking and unstacking and excessive handling of the chairs creates a wear condition on the non-frame portions such as the upholstered portions which oftentimes damages the upholstery and generally minimizes its life. It is the principal object of this invention to provide a stacking chair which has a protective frame around the non-frame portions and which is of a novel construction permitting the framing construction to be economically manufactured, but still very effective for maximizing protection of the non-frame portions.
- the general construction covered by this invention might well be considered for the seat portion of a stacking chair, it lends itself especially to the back portion.
- the back portions of the stacking type chairs are subject to a sliding action as the chairs are stacked and the construction of this invention particularly minimizes the wear conditions created by this sliding action.
- Such a condition is not so extreme with the seat portions of a stacking chair because the stacking of the chairs does not create any particular sliding action between the seat portions which come directly into contact with each other without any appreciable sliding movement.

Description
Dec. 13, 1966 E. J. STRAITS CHAIR CONSTRUCTION Filed Nov. 4, 1965 frzz/eiraiaw T: fimesi If WQZZZJT United States Patent 3,291,529 CHAIR CONSTRUCTION Ernest J. Straits, 712 S. 6th St., St. Charles, Ill. Filed Nov. 4, 1965, Ser. No. 506,316 4 Claims. (Cl. 297445) This invention relates to the art of chair construction and particularly to improvements in back construction for a chair.
To meet the requirements of institutional or meeting hall type usage, for storage purposes a stacking type of chair has become very popular and common. Such a stacking chair is ordinarily designed to be stacked one upon another with a large number of chairs in a single stack, but superimposed close to each other so that a minimum of space is employed.
In order to facilitate moving the chairs, a handle attached to the chair is also employed. It is one of the objects of this invention to provide a handle construction for such a chair which blends into the harmony of the chair construction and is recessed so that it is relatively protected from physical abuse to which the chairs are ordinarily subject.
Another important problem with stacking chairs is that the stacking and unstacking and excessive handling of the chairs creates a wear condition on the non-frame portions such as the upholstered portions which oftentimes damages the upholstery and generally minimizes its life. It is the principal object of this invention to provide a stacking chair which has a protective frame around the non-frame portions and which is of a novel construction permitting the framing construction to be economically manufactured, but still very effective for maximizing protection of the non-frame portions. Although the general construction covered by this invention might well be considered for the seat portion of a stacking chair, it lends itself especially to the back portion. It should be emphasized that the back portions of the stacking type chairs are subject to a sliding action as the chairs are stacked and the construction of this invention particularly minimizes the wear conditions created by this sliding action. Such a condition is not so extreme with the seat portions of a stacking chair because the stacking of the chairs does not create any particular sliding action between the seat portions which come directly into contact with each other without any appreciable sliding movement.
Other objects and advantages of the invention should become apparent upon reference to the accompanying drawings in which:
FIG. 1 shows a three-quarter front perspective view of a chair embodying the preferred features of the invention;
FIG. 2 is a front elevation view of only the upper back portion of the chair shown in FIG. 1;
FIG. 3 is a sectional view along the line 3--3 of FIG. 2 and particularly shows the upper rim construction of the seat back;
FIG. 4 is a sectional view along the line 4-4 of FIG. 2 and particularly shows the lower rim portion of the seat back; and
FIG. 5 is a partial cut-away and sectional view of the lower corner of the back of the chair as shown in FIG. 2 and particularly shows the connection between the seat back and the framing portions for it.
As shown in FIG. 1, the chair 1 consists of an upper frame 2 which suitably supports a seat cushion 3 which may be fastened to it by means of screws or other suitable fasteners commonly employed. The frame 2 has two substantially vertical arms 2a and 2b which extend upwardly and frame the two sides of a back cushion 4.
The upper edge of the back cushion 4 is held in place by an upper channel member 5 which is connected at its ends 5a and 5b to the upper ends of the arms 2a and 2b of the upper frame 2. The lower edge of the back cushion is held in place by means of a channel member 6 which is secured at its ends 6a and 6b to lower portions of the arms 2a and 2b as is hereinafter described.
Welded or otherwise fastened to the edge regions of the lower portions of the frame 2 are two downwardly depending leg frames 7. Each of these leg frames 7 is provided with two legs 7a and 7b which form the depending portions of the frame members 7. These legs 7a and 7b are downwardly divergent and are arranged in such a manner that they will nest with legs of identical chairs positioned one upon the other. This nesting action between the chairs is further permitted by having the back frame 2 directed upwardly at a slight angle beyond the vertical.
As particularly shown in FIGS. 2 through 5, the upper channel member 5 has a mid-portion So which is recessed relative to the end portions 5a and 5b. This recessed portion 50 is connected by two intenmediate portions 5d and 5e which provide the connection between the recessed portion 50 and the ends 5a and 5b. A handle 8 is permanently secured at its ends to these portions 5d and 5e of the channel member 5. With this arrangement, the recessed portion 50 provides clearance so that the handle 8 can be gripped conveniently with portions of the hand extending between the handle 8 and the recessed portion 5c. At the same time, the handle 8 does not extend above the level of the ends 5a and 5b of the channel member 5 so that it is protected from snagging or engaging other objects as the chair is manipulated during stacking, unstacking and otherwise.
The back cushion 4 is shaped at its upper edge to conform to the shape of the channel member 5 and, as particularly shown in FIG. 5, the upper edge of the back cushion 4 is recessed within the channel member 5 where it is fully protected.
The side portions of the back cushion 4 are of the same shape as the arms 2a and 2b of the upper frame 2 so that they closely abut the arms 2a and 2b without any spacing.
The lower edge of the back cushion 4 fits into the lower channel member 6, as particularly indicated in FIG. 4. In this manner, the lower edge of the back cushion is well protected. This lower channel member 6 is secured at its ends 6a and 6b to the arms 2a and 2b of the upper frame 2 by means of two L-shaped clips 9. One leg 9d of each of the clips 9 is secured in a slightly recessed portion 9a in either of the arms 2a and 2b and welded in place. The dimensions of the recess and the clip are such that the surface 91) of the clip is flush with the inner edge 20 of each arm 2a or 2b. The clip 9 has its other leg extending substantially perpendicular to the leg 9d and it is positioned along the inner surface 60 of the channel member 6. Each leg 90 is provided with a tapped hole 9e which is aligned with a hole 6d and a screw 10 is provided through these holes to secure the channel member 6 to the clip 9. With the leg 90 concealed in the channel 6 and with its other leg 9d concealed within the recess 9a of each arm 2a and 2b, the clip is completely invisible when the chair is completely assembled. Another advantage is that the channel member 6 provides a rigid brace for the chair back and a very effective edge protection for the back cushion 4.
In order to provide clearance to permit placement of the back cushion 4 in the upper channel member 5, the clip legs 9c are initially bent downwardly as indicated by dotted lines in FIG. 5. After the back cushion 4 is positioned, the leg 9c is bent up to the position shown in solid outline for final assembly.
Although the back cushion 4, as indicated in FIGS. 3 and 4, is indicated as one having a padding material 4a and a rigid backing member 4b covered with a flexible cloth or plastic covering 40, other internal constructions are possible without deviating from the scope of the invention. It is significant, though, that the construction shown is very durable because the back cushion 4 is well protected by its framing members 2a, 2b, 5 and 6 which hold it securely in place and protect all of its edges. A feature which enhances protection of the edges is that the channel members 5 and 6 wrap around the edges of the back cushion and project from it by an amount equal to the thickness of the material from which the channel members are made. In this manner, any severe sliding contact of one chair over another occurs primarily along the edges of the channel members. Similarly, the arms 2a and 2b withstand severe sliding contact. Even though the main body of the back cushion 4 comes in contact with other objects, such as other chairs being stacked with it, the frame portions 2a, 2b, 5 and 6 ordinarily prevent undue compression and Wear of the back cushion 4.
Although only a single embodiment of the invention has been shown and described, it should be clearly understood that the invention can be manufactured in other ways without departing from the true scope of the invention as defined by the appended claims in which:
