OFF-ICE ROTARY SWING William Dane, Elmont, N, Y.

Application September 6, 1940, Serial No. 355,694 I (01. 155-58) Claims. My invention 'rlates to improvements in swings.

An important object of this invention is to provide a seat in which a person may swing for amusement or mild exercise while procuring the benefits of a periodic ray treatment.

Another object of this invention is to provide a swing with means to regulate the duration of the treatment and yet have the body exposed to the open air.

' "A further object of the invention is to provide a swing which isrotatable about a vertical axis to enable aperson to follow the course of the sun to secure maximum solar intensity on a predetermined section of the body. 7

Another object is to provide a safe, easily oscillating swing for use in sun treatments.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing,

Figure 1 is a front view of a rotary swing embodying my invention,

Figure 2 is a plan View of the swing with parts broken away to show the details of constructio more clearly,

Figure 3 is a central vertical longitudinal section on the line 3-3 of Figure 2, and

Figure 4 is an enlarged section on the line 44 of Figure 3 illustrating the swing suspension and anti-friction bearings.

In the drawing, where for the purpose of illustration is shown a preferred embodiment of the invention, the reference numeral 5 indicates a slab on which the swing structure rests. A vertiends of crossbar l2. *A'bar I1 is attached to the outer marginof the awning. Cords I8 are attached to the bar and pass through guide eyecal shaft 6 is rigidly mounted in the slab 5 and extends into an aperture 1 in a base member 8 to constitute a journal. Base member 8 is preferably a strong platform disk having wheels 9 radially mounted on the disk periphery in any convenient manner to permit easy rotation of the disk about the verticalaxis 6. Abutment I0 is firmly attached to the platform disk 8 and provides an easy means for rotating the platform to a desired position by an easy push with the operators foot. 1

Vertical posts I I of convenient height are firmly attached to the platform disk 8. A crossbar l2, secured by suitable fasteners, serves to hold the columns ll together at their upper ends. The posts ll may be braced as at l3 to maintain them in a rigid vertical position at all times.

A canopy l4, preferably of fabric, is slidably mounted on rods l5 which are connected at two ends to anchors or loops 16 near the opposite lets or hooks 19 inserted in crossbar l2 and extend along post ll. Aneasy tug on cords l8 pulls bar I1 and serves to draw the awning along rods I5 into a compact position near the top of the frame. If desired, similar control means (not shown) may be employedto draw the awning to an open position.

Beneath crossbarl2 2. horizontal shaft 20 is securely mounted in columns H. Spaced rigid posts 2i depend from shaft 20 and at a sufficient distance out of contact with columns ll. Attached to the lower ends of pendulum members 2! is a seat structure 22. Below the seat a foot rest 23 is suspended by slender straps 24 so as to permit a free passage of sunlight to the back of the legs.

Pendulum members 2| are suspended from shaft 20 through anti-friction bearings 25. See Figure 4. Sleeve sections 26 encompassing shaft 20 space the pendulum members from each other and the columns II to accurately position the swing in its proper position between the uprights at all times.

The operation of the machine is as follows:

The person desiring a sun treatment steps on the platform 8 and seats himself in the swing with his feet on the rest 23. The pendulum posts 2| may be grasped for support. The patient may swing or be swung by an attendant while securing a sun bath. A tug on cord l8 will collapse the awning and permit the sun or other rays to reach the patient.

The backless construction of the seat and the open suspension of the footrest permit the sun to reach the patients dorsal regions to an almost unrestricted extent.

The entire swing structure may be rotated about the vertical pivot l to enable a desired portion of the patients body to face the direct rays of the sun. An individual standing on slab 5 may push on abutment It with his foot or thrust on column H with his hand and rotate the platform on its rollers 9 through the necessary are. This enables the maximum ray intensity to be directed on the part of the body under treatment. In the same manner the swing may be rotated to follow the sun in its orbit,

Thus the patient may secure the most effective treatment.

The awning 14 may be extended by sliding it along bars l5 to shield the patient from the sun when his skin has been given its exposure for struction, but that various changes and adaptions may be made therein without departing from the spirit of my invention as hereinafter claimed.

I claim:

1. An orientable unit of the character described, comprising, in combination, a rotatable support having a rotation axis of fixed position, a frame mounted on the rotatable support and extending upward therefrom on opposite sides of a vertical plane through said rotation axis extended, and a swing seat depending from said frame and free to oscillate with respect to the same.

2. An orientable unit of the character described, comprising, in combination, a rotatable support having a rotation axis of fixed position, a frame mounted on the rotatable support and extending upward therefrom on opposite sides of a vertical plane through said rotation axis extended, a swing seat depending from said frame and an adjustable canopy rotatable with the support and frame for shading the seat.

3. An orientable unit of the character described, comprising, in combination, a rotatable support having a rotation axis of fixed position, a frame including two spaced members mounted on the rotatable support and extending upward therefrom on opposite sides of a vertical plane through said axis of rotation extended, at least one rigid swing post depending from said frame between said frame members and having a swing seat connected with the free end thereof.

4. An orientable unit of the character described, comprising, in combination, a rotatable support having a rotation axis of fixed position, two spaced upright frame members mounted on said support on opposite sides of a vertical plane through said rotation axis extended, a crossbar connecting the upper portions of said frame tion axis of fixed position, a frame mounted on i the rotatable support and extending upward therefrom on opposite sides of a vertical plane through said axis of rotation extended, and a swing seat depending from said frame and free to oscillate with respect to the same.

WILLIAM DANE.
