3 Claims.

My invention relates to gliders, and more particularly to those of the flexibly-suspended or swinging type.

One object of my invention is to provide a swing or glider of such form that it has smoother movement than various types of swings heretofore produced.

Another object of my invention is to provide a glider wherein friction such as results in squeak ing is avoided.

Still another object of my invention is to pro vide a gliderwherein there is more effective resistance to side sway than in swings of various other types.

A further object of my invention is to provide an improved arrangement or structure for gliders, which is of simple form, and nevertheless possesses sufficient rigidity, and one which can be readily disassembled to knock-down condition.

One form which my invention may take is shown in the accompanying drawings wherein Figure 1 is a front view of the glider; Fig. 2 is an end view thereof; Fig. 3 is an enlarged view taken on the line IIIIII of Fig. 1; Fig. 4 is a front view of the structure of Fig. 3, partly in section; Fig. 5 is an enlarged view taken on the line V-V of Fig. 1; Fig. 6 is a view taken on the line VI-VI of Fig. 5; Fig. 7 is a view taken on the line VII-VII of Fig. 1; and Fig. 8 is a sectional plan view of the structure of Fig. 7.

The glider comprises a stationary supporting structure from which a swinging frame is flexibly supported. The stationary portion of the structure comprises end frames, each of which has a base or floor .bar III, a pair of uprights II, a second pair of uprights l2, and a top rail or strap l3. The bottom or base bars l0, of course, rest upon the floor or other supporting surface. The uprights II are secured to the base bars and the uprights l2, preferably by arc welding, but could be bolted in place, if desired. The top rail I3 is welded or otherwise secured to the uprights l2, and such uprights, together with the top rails l3, are bent downwardly at their ends, and suspending strips I 4, preferably of spring steel or the like, are rigidly secured at their upper extremities to said down-turned ends. There is, of course, one suspending strip It at each corner of the structure, and the swinging frame is secured to the lower ends of these suspending strips, as hereinafter explained.

The lower ends of the uprights l2 are curled to form eyes that are welded to the base bars It, as shown more clearly in Figs. 5 and 6, for receiving stud bolts It, the outer ends of the bolts 16 having nuts I! which will permit disconnection of the end frames. The end frames are connected together by a tie bar l8 which is shown as of angular form in cross section. The inner ends of the stud bolts l6 are welded to the inner walls 5 of the tie bar. It will be seen that when the uprights l2 are in place and the nuts I! screwed up tightly, the end frames are held in rigidly-assembled position.

The swinging frame is provided at each of its 10 front corners with a bar 20 that is disposed mainly in vertical position, but has its upper end bent outward to overlie the top rail I3, and at its lower end is bent outwardly and twisted to a vertical plane at 2| and bolted to the lower end 15 of one of the strips Ill. The frame carries an upright bar 22 at each of its rear corners, and these bars are similarly bent, to overlie the top rail and for attachment to the rear hanger strips M. A shield plate 23 is secured against the outer 20 sides of each pair of uprights 20-22, and serves as an arm rest, as well as to protect the clothing of the users from getting caught in the stationary frame members II and I2 when the glider is in motion.

A cross rail 25 has hooked engagement at its ends withthe front uprights 20, as shown more clearly at 26 in Figs. 1 and 4. A similar cross rail is connected in like manner to the rear uprights 22, as shown in Fig. 2. Angle bars 21 are 30 welded or otherwise secured to the cross rails 25 at the front and rear sides of the swinging frame. The members 25 and 21 serve as a support for seat cushions, or a mattress, or a spring bottom.

A back frame includes a bottom bar ,or rail 29, 35 a top rail 30 whose ends are bent down and secured to the rail 29 and cross bars 28. The ends of the bottom rail 29 are extended, so that they abut against the rear sides of the uprights 22. The back frame is provided at each end with a hook 40 member 3|, which has engagement'with a pin or stud 32 that is provided in each of the uprights 22.

As shown more clearly in Fig. '7, the hook members 3| are provided with notches which permit 5 of supporting the back frame at different degrees of inclination, according to the desires of the user. Back cushions 33 are shown as supported by the back frame.

Because the stationary end frames are com- 50 posed mainly of flat strips such as Hi, It and I2, in combination with the tension rail IS, the structure is of reasonably light weight, and is nevertheless resistant to distortion or swaying through thrust forces endwise of the seat, and endwise 66 Y swaying of the seat itself is resisted by reason of the suspending strips H being rigidly connected at their ends to the seat frame and the end frames and disposed flatwise with respect to the front of the seat, in parallelism with the wider faces of the uprights I l and I2 of the end frames.

I claim as my invention:---

1. A glider comprising a pair of end frames each having a floor bar, a top rail, two uprights of spring metal connected at their lower ends to mid points of the floor bar, and respectively bent forwardly and rearwardly at their vupper ends and connected to the ends of the top rail; and a. second pair of uprights each connected at its lower end to the floor bar at a point intermediate the said mid points and an extremity of the bar, and con-- nected at its upper end to an intermediate point in the said bent portion of one of the first-named uprights, a seat frame disposed between the end frames, and flexible suspending members each connected to a top rail and a comer of the seat frame.

2. A glider comprising a pair of end frames each having a floor bar, a top rail, two uprights of spring metal connected at their lower ends to the floor bars, and respectively bent forwardly and. rearwardly at their upper ends and connected to the ends of the top rails, a seat frame disposed between the end frames, and flexible suspending members respectively connected to the ends of the top rails and to the seat frame.

3. A glider comprising a pair of end frames each having a floor bar, a top rail, two uprights of spring metal connected at their lower ends to the floor bar, and respectively bent forwardly and rearwardly at their upper ends, the upper ends of the uprights being spaced apart further than the lowerv ends thereof, and connected to the ends of the top rail, a seat frame disposed between the end frames, and flexible suspending members respectively connected to the ends of the top rails and the seat frame.
