Williams and Warren P. Miller, Anderson, Ind., assignors to American Playground Device Co., Anderson, had, a corporation of Indiana Filed June 15, 1960, Ser. No. 36,435 1 Claim. (Cl. 297280) This invention relates to swing structures and more particularly to swing seat constructions for use for small preschool age children.

An object of this invention is to provide a novel contoured swing seat, of simple and inexpensive, but durable construction, for use in supporting small children. Another object of this invention is to provide a novel and improved contoured nursery swing seat rapidly usable for small and pro-school age children and which is shaped and anatomically contoured to provide a safer and more comfortable ride than any heretofore known comparable swing seat devices.

A further object of this invention is to provide novel and improved anatomically contoured swing seat, designed to assure strength and durability, including rigid suspension members arranged and constructed to cause a load exerted on the swing seat to be evenly distributed thereon when the swing seat is in load-bearing condition thus assuring a long life to the swing seat.

A further object of invention is to provide an anatomically contoured seat which may be fitted with legs and used as a play chair for small children and other similar uses.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference character refer to the same or simi lar parts throughout the several views and in which:

FIG. 1 is a side elevational view of the novel contoured swing seat construction;

FIG. 2 is a top plan view of the contoured swing seat construction taken approximately along line 2-2 of FIG. 1 and looking in the direction of the arrows;

FIG. 3 is a front elevational view of the novel contoured swing seat taken along a line 3-3 of FIG. 1 and looking in the direction of the arrows;

FIG. 4 is a top plan view of the attachment and reinforcing member;

FIG. 5 is a side elevational view of the attachment and reinforcing member; and

FIG. 6 is a cross-sectional View taken approximately along line 66 of FIG. 5,

Referring now to the drawings it will be seen that our novel contoured nursery swing seat, designated in its entirety by the reference numeral 10, is of integral construction, as best seen in FIGS. 1 to 3. The contoured swing seat 10 is preferably molded from strong durable Fiberglas reinforced plastic to present a rather light, but highly durable structure. 'This Fiberglas reinforced plastic, which is impervious to water, will not conduct or retain heat, and is there-fore ideal for outside use. In the preferred embodiment the nursery swing seat 10 be colored and the color will be molded into the seat, thus giving the swing seat a very pleasing appearance throughout the life of the swing seat.

This contoured nursery swing seat 110 includes a seat portion 11 which is inclined downwardly and rearwardly and has a downwardly and outwardly curved front flange 12, as best seen in FIGS. 1 and 3. The swing seat 10* also includes a back rest portion 13 which is integrally formed with the seat portion 11 and extends upwardly adjacent the rear thereof and terminates in an outwardly and rearwardly flared peripheral flange portion 14.

Side portions 15 are integrally formed with the back rest portion 13 and seat portion 11 and extend forwardly from the back rest portion and upwardly from the seat portion 11. These side portions 15 have outwardly turned upper peripheral flange portions 16 which actually define arm rests as best seen in FIG. 2 and the side portions also have outwardly turned but vertically disposed peripheral flange portions 17 which are continuous with the front flange portion 12 of seat portion 11. The outwardly flared upper peripheral flange portions 16 are continuous with the front flange portions 17 of the side portions and also continuous with the peripheral flange portion 14 of the back rest 13. It will therefore be seen that while the nursery swing seat 10 is of integral construction a continuous outwardly curved peripheral flange is provided to thereby insure comfortable use of the swing seat by small children.

Means are provided for connecting the nursery swing seat 10 to conventional depending chains which are secured to a swing frame structure so that the swing seat may be moved in oscillating fashion relative to the supporting structure. These interconnecting means comprise rigid suspension members 18 which, as best seen in FIG. 1, are of rigid, substantially inverted V-shape construction. In the preferred embodiment the suspension members .18 are preferably formed from cold rolled steel rods which are cadmium plated for appearance and long life and each of these suspension members includes a pair of diverging legs 19' connected by a small loop or high-t portion 20. The lower ends of the legs 19 are threaded as at 21 as best seen in FIG. 1.

A pair of elongate reinforcing and attachment members 22 preferably iormed of galvanized steel or the like are disposed in abutting relation beneath the undersides of the arm rests 16. Each of these attachment members 22 is secured to its associated suspension member 18 adjacent the lower free ends of legs 19 thereof. It will be seen that each of the attached members 18 is provided with apertures 23 adjacent each end thereof and these apertures are arranged in registering relation with corresponding apertures formed in the arm rests 16 to thereby permit the legs 19 of each of the suspension members 18 to extend therethrough. A look nut 24 of conventional hexagonal configuration cooperates with a stop nut 25 to secure the lower threaded ends of suspension members 18 to the reinforcing and attachment member 22 and the arm portion 16 of the swing seat 10. It will be seen that the suspension members 18 are connected to their associated arm rest portions 16 at widely spaced points therealong and each of these suspension members cooperates with its associated reinforcing attachment member 22 to reinforce the arm rest along their entire longitudinal extent. These members 22 are of curved crosssectional configuration and each has an upwardly curved rear portion to cooperate with the correspondingly shaped portion of the arm rests 16.

The contoured nursery swing seat 10 is also provided with a retaining bar 26 which extends between and is slidable on the suspension members 18 This elongate safety retaining bar is preferably formed of hardwood, the ends of which are provided with suitable apertures 27 through which extend the forwardmost legs 19 of each of the suspension members 18 so that the retaining bar 26 is mounted on the suspension members for vertical sliding movement relative thereto. It will also be noted that retaining bar 26 is provided with a cover 28 of heavy linear polyethelene which may be peppermint striped or otherwise colored for added appearance and appeal.

This uniquely constructed contoured nursery seat is especially safe and anatomically contoured for use by small children. When the swing seat 10 is in use, it will be suspended for support by conventional chains which will be connected to the bight or loop portion 20 of each of the suspension members 18. These uniquely constructed inverted V-shaped suspension members 18 actually cause the load exerted on the swing seat, when the latter is in load-bearing relation, to be evenly distributed thereon so that the swing seat will be subjected to even wear, thus insuring a maximum durability and much longer life.

It is also pointed out that not only are the arm portions 16 reinforced throughout their respective lengths by the cooperative relation between the reinforcing and attachment member 22 and the suspension members '18, but the entire side portions are reinforced by means of the retaining bar 26 which extends between the suspension members 18. The diverging leg portions '19 of each suspension member are rigidly interconnected by their associated bight or loop portions and since the retaining bar 26 extends between the forwardmost of these legs 19, the rearmost parts of the side portions 15 will also be reinforced and load stresses will be transferred evenly from the swing seat to the suspension member and thereafter to the associated suspension chains.

The seat portion 11 is provided with an elevated central front portion 11a as best seen in FIGS. 2 and 3 and the rearwardly inclined configuration of the seat portion 11 cooperates with the central portion 11a to eliminate any tendency of the child to slip forwardly from the swing seat during oscillation thereof. The rearwardly sloping seat which terminates in an upwardly and outwardly curved back rest portion cooperates with the side portions to not only present a safe, durable construction, but one in which the child may enjoy a more comfortable ride than any heretofore known swing seat construction.

It will be noted that the various portions of the seat 10 generally curve and blend together so that there are no sharp corners, and as pointed out above, the swing seat is shaped and contoured to also eliminate any tendency of the child to be accidentally displaced therefrom.

It will therefore be seen from the foregoing description that we have provided a nursery swing seat which is readily usable by small children and is arranged and constructed to function in a more efiicient and safe manner than any heretofore known comparable devices. It will be noted that the uniquely constructed nursery swing seat is not only of light, durable construct-ion, but also presents a highly pleasing appearance. It will therefore be seen from the preceding paragraphs that we have provided a novel nursery swing seat which will provide small children many hours of pleasure.

It will, of course, be understood that various changes may be made in the form, detail, arrangement and proportion of the parts without departing from the scope of our invention which consists of the matter described herein and set forth in the appended claim.
