3 Claims.

My invention relates to gliders ofthe swing type, and has for one of its objects the provision of a glider structure which, while it may be formed of metal members which are of light 5 Weight compared to the structures of previous gliders, is nevertheless of sufficient strength and rigidity.

Another object of my invention is to provide a glider structure which can be readily disassembled or knocked down, and which is of minimum overall length.

One form which my invention may take is shown in the accompanying drawings wherein Figure l'is a face View of the glider; Fig. 2 is an end View thereof; Fig. 3 is an enlarged view taken on the line IIIIII of Fig. 2; Fig. 4 is an enlarged side view of a portion of the structure of Fig. 2; Fig. 5 is a view taken on the line V-V of Fig. 4; Fig. 6 is aview taken on the line VIVI of Fig. 2, and Fig. 7 is an enlarged face view of aportion of the structure of Fig. 1.

The seat framework of the glider has at each end thereof, a yoke-like member 9 having an arm rest portion I and depending front and rear leg-like portions H and I2, respectively. A rear seat bar I3 and a front seat bar I4 have welded thereto at each end a bar I5, the bars I3, I4, and I being preferably in the form of angles. Box springs IE or other cushion-supporting elements are supported by the angles I3, I4, and I5.

Brace bars I! connect the leg elements II and I2 at each end of the seat structure, the ends of the bars I? being laterally turned and welded to said leg elements. The use of these brace bars permits the yoke members 9 to be made of lighter gage material than would otherwise be possible. The bars I'I also serve to prevent engagement of the cushions with the stationary end frames.

A back frame I8 has an angle bar I9 welded to its lower end, the bar I9 extending the full length of the seat frame. A link member 2|, at each end of the seat frame, has one of its ends pivotally connected to the back frame I8 and its other end pivotally connected to its associated end bar I5. The bar I9 abuts against the rear sides of the links 2| and rearward tilting movement thereof is prevented, although it can be folded forwardly, when desired. The lower portions of the bars 2I seat against the upwardlyexposed faces of the bars I5. The pivotal connections of the links 2I are, of course, removable, in order to facilitate disassembling of the structure.

In order to provide for a firmer connection between the seat bars, I provide a yoke bar 23 at each end of the seat frame. The bars 23 are welded to the leg members II and I2 and have their ends inwardly turned, such ends extending beneath the bars i5 and lying within the angles of the bars I3 and I4. The said inner ends carry pins or buttons 24 that have interfitting engagement with key hole slots formed in the bars I 3-I 4, as shown more clearly in Figs. 6 and 7.

The bars I5 and the pin and key hole connections referred to maintain the parts in rigid relationship. In order to overcome danger of accidental disconnection of the pins 24 from the key hole slots, the bar 23 may be slitted slightly to permit of tongues 24a being struck up therefrom, and bent to the position shown in Fig. 7, between the ends of the bars I3 and I4 and the legs I2-I I, respectively. However, by disengaging the key hole connections and disconnecting the links 2|, the seat frame structure can readily be knocked down for shipment or storage.

The stationary portion of the structure includes a pair of end frames each having a floor bar 26 that may suitably be provided with rubber caps or pads 21; a pair of supporting bars 28 disposed in crossed relation, and a top rail 29. Brace bars 3I are connected at each end to the uprights 28. These bars may suitably be of angular form and have the heads of bolts 32 welded therein, the bolts extending beyond the ends of the bars, and through the uprights 28. When nuts are attached to the bolts, the end frames are thereby rigidly connected.

The lower ends of the crossed bars 28 are welded to the sides of the floor bars 25, and their upper ends are welded within the groove or channel portions of the top rails 29, and may be welded at their points of crossing. One bar 28 of each pair is offset somewhat, as shown more clearly in Fig. 6, so that the ends of the uprights where they are connected to the floor bars 26 and. to the top rails 29, will lie in a common plane in each instance.

The seat frame is supported upon stationary end frames, at its four corners, by strap-like members 34 which are here shown as of spring steel; although these hanger members could be in the form of links. However, I prefer to use the spring strap hangers, because they permit of a smoother and noiseless swinging movement and resist any thrusts which tend to produce end sway of the seat.

The upper ends of the straps are connected to the down-turned fiat portions of the top rails 29, by means of bolts 35. While the straps 34 will ordinarily flex at various points throughout spring plates 37 being employed in the same 'manner as the spring plates 36.

It will be noted that the yoke members 9 of the seat frame are positioned over and lie in the same planes as the stationary end frames. In order to prevent interference by these yoke members with swinging movements of the seat frame,

the arm rest portions H! are made of considerably greater length than the leg portions and therefore are inclined downwardly toward one another, for connection to the lower ends of the verticallyextending straps 34.

Since the seat bars are inclined relative to the yoke-like member 9 and the end frames, with a higher point of connection with the legelements H than with the legs [2, and the yoke members 9 are of light gauge material, stiffening strips 39 are welded to the rear sides of the front legs I l.

I claim as my invention:

1. A glider comprising a pair of stationary end frames each of which includes a top rail, a floor bar, a pair of substantially flat uprights disposed in relatively crossed relation and secured at their upper and lower ends to the top rail and the floor bar, respectively, one of the uprights being offset nel form and having down-turned ends, a floor bar, a pair of substantially flat uprights disposed in relatively crossed relation and secured at their upper and lower ends to the toprail and the floor bar, respectively, one of the uprights being offset to cause their upper and lower ends to occupy a common vertical plane, suspending elements connected to the ends of the top rails, andseat-supporting legs connected to and extending upwardly from the lower ends of the suspending elements, the legs, the toprail and the uprights, at each end of the glider, being disposed in a common vertical plane.

3. A glider comp-rising a pair of stationary end frames each of which includes a top rail, a floor bar, a pair of uprights secured at their upper and lower ends to the top rail and the floor bar, respectively, suspending elements connected to the ends of the top rails, seat-supporting legs connected to and extending upwardly from the lower ends of the suspending elements, in relatively flared directions, and an arm rest carried by the upper ends of the legs, the legs, the arm rest, the top rail and the uprights, at each end of the glider, being disposed in a common vertical plane.

WILLIAM G. HARDY.
