and concealed when the chair is in its unfolded useful position.
We have heretofore filed an application upon a folding chair, having Ser. No. 689,949, filed August 12, 1946, now abandoned. The present application is a continuation thereof with improvements in structure which better the structure shown in the prior application and by means of which the chair may be more economically manufactured and have a better appearance.
An understanding of the invention may be had from the following description, taken in connection with the accompanying drawing, in which,
Fig. 1 is a perspective view of the folding chair in its unfolded useful position.
Fig. 2 is a fragmentary enlarged perspective view, illustrating the connecting between the upper ends of the back legs of the chair to the front legs thereof. I
Fig. 3 is a horizontal section, substantially on the plane of line 33 of Fig. 2.
Fig. 3a is a similar section on the plane of line 3a3a of Fig. 1.
Fig. 4 is a side elevation of the folded chair.
Fig. 5 is a fragmentary rear elevation, at one side of the folded chair shown in Fig. 4.
Fig. 6 is a partial vertical section and a rear elevation, the section being taken on the plane of line 85 of Fig. 4.
Fig. 7 is a fragmentary vertical section and side elevation, the section being taken on the plane of line 'II of Fig. 5.
Fig. 8 is a fragmentary vertical section substantially on the plane of line B8 of Fig. 5, and
Fig. 9 is a similar section showing the parts in a different position, Fig. 8 being the folded position of the chair and Fig. 9 the useful, unfolded position thereof. Like reference characters refer to like parts in the different figures of the drawings and the sections are taken looking in the directions indicated by the arrows associated with the section lines.
In the disclosed structure, a front frame of inverted U-form has spaced apart legs I which are integrally connected by a U-shaped bend 2 at their upper ends. Preferably, substantially at the joinder of the straight legs I with the U-bend 2, a bend, as indicated at 3 is made in each side of the frame so that the upper bend portion is inclined forwardly at an angle to the plane of the spaced legs I. It is, however, to be understood that such bends as indicated at 3 need not be used and will not be used in one form of chair. A back supporting member 3 of any desired structure is secured to and fills the upper U-bent portion. Such front frame in the use of the chair inclines upwardly and to the rear, as shown in Fig. l, and is supported by two spaced rear legs 5 foldably connected to the front legs I as hereafter described. At the lower ends of each leg I and 5, floor engaging feet 6, preferably are attached.
Such frame with the legs I, and the rear legs 5 are formed from lengths of sheet metal which are bent and shaped to provide oppositely spaced parallel sides I, connected integrally by an are shaped bend 8 which will be at the front of the front legs I and at the rear of the rear legs 5 each side I. At the back of the front legs and at the front of the rear legs flanges 9 are bent inwardly at right angles toward each other to and from the sides I. Such flanges come together except that between the upper and lower ends of the front legs I, sufficient metal 'is removed to provide in the rear side of each of the legs I an elongated relatively narrow slot It]. Each slot IE! at the upper end portion may be further widened as indicated at Iila for reasons hereafter appearing. The two front legs I and the two rear legs 5 adjacent their lower ends have rods I I extending between and permanently connected therewith by welding or any other equivalent connecting means for reinforcement and extending said legs to prevent their separation.
Each of the rear legs 5 has the metal of the sides l turned inwardly toward each other to make an abutment I2 at the upper end of each rear leg; and from the edges of the flanges turned in to make such abutment, two spaced ears I3 extend upwardly. A link I4 of flat metal is pivotally connected atone end to and is located between each pair of ears I3 at the upper ends of the legs 5. The links I4 extend through the slots I0 and at their inner ends have pivotalconnection to bars I5 formed of flat metal which are permanently and rigidly secured one within each of the front legs I. Said links I lhave a pivotal connection to the upper ends of the bars I5 which are somewhat elongated over what is required for such pivotal connection, to strengthen and reinforce the front legs I and to dispense with making such bars in rights and lefts, for the right and left front legs.
Two additional rods I6 are located one between the spaced front legs I, and the other between the spaced rear legs 5. The rod I6 between the front frame legs I preferably extends through the inner sides of said legs and have a permanent and rigid connection to the bars I5, so that said bars I5 provide a support of greater strength for such rod upon which the chair seat is mounted for folding movement. The rod I8 between the back legs 5 is a distance below the upper ends of said legs and to it the folding seat of the chair is connected at its rear under portion.
The chair seat which may be made in many specific ways preferably includes two spaced side bars I! of a generally angular form in cross section having vertical and horizontal legs. Between the horizontal legs a steel supporting bottom of a seat I8 is located and secured. The side bars I1 are mounted on the front rod I6 at a distance from the rear edge of the seat, and the rear edge of the seat is connected to the rear bar I6. The seat above the side bars I1 and its metal bottom It may be finished in any desired material, as by upholstering padding underneath a cover therefor, by a wood veneer panel secured in place, or in various other ways to provide the form of the seat wanted.
The upper ends of the rear legs 5, at the abutments I2 when the seat is folded as in Fig. l, are inclined to both the horizontal and vertical. When the folded seat shown in Fig. 4 is to be unfolded to the position as in Fig. 1, the legs I and 5 are separated at their lower ends and the seat turned downwardly whereupon links I4 (Figs. 1 and 4) automatically swing in a counter-clockwise direction and pass, together with ears I3 through the slots It] and are located wholly within the hollow legs I (Fig. 9) with the abutments I2 of the rear legs 5 against the flanges 9 at the rear sides of the front legs I. The seat likewise is simultaneously swung or turned about the front rod I6 in a counter-clockwise direction from the substantially vertical folded position g hown in Fig. 4 to the horizontal position as in The chair is of novel structure, and economical to produce. When in its useful position, Fig. 1, it has a distinctive and attractive appearance, the links I4 and ears I3 being wholly concealed and the abutment provided at the upper end of each rear leg 5, at I2, being snugly against the flat rear sides of the front legs I, providing smooth joints without unsightly projections. The channel form, in cross section of the legs, with opposite rounded and flat sides gives strength and rigidity to the structure, and is one which is readily fabricated. The reinforcement and strengthening provided by the bars I5 add to the value of the chair and provide increased strength for support of the seat and an weight thereon. The slots II] at their upper ends may be widened as much as necessary for the passage of the ears I3 and for the heads of the pivot which connect said ears with the links I4, as indicated at Illa.
The structure is a marked improvement in the art of folding chairs in its provision of a sturdy and durable, economically produced chair, and one which may be folded to occupy small space. It is light in weight and has a particularly desirable appearance.
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
