WINDOW CHAIR Filed Sept. 21, 1931 vlllllllllllllunlrlrllr II v 'IJWIIIIIIIIIIII'IIIIIIIIA 660:?6 5098a cf)? INVENTOR Hrs ATTORNEYS Patented May 3 3, 1933 PATENT OFFICE GEORGE SVEJDA, JR., OF CHICAGO, ILLINOIS WINDOW CHAIR Application filed September 21, 1931. Serial No. 564,160.

This invention relates to certain novel improvements in window chairs, and has for its principal object the provision of an improved construction of this character 5 which will be highly efficient in use and economical in manufacture.

It is an object of this invention to provide an improved safety window chair.

Another object of the invention is to provide new, efficient, and inexpensive means to secure the chair in the window and thereby to insure the safety of the occupant.

A further object of the invention is to provide new, efiicient and inexpensive means to prevent side sway or lateral motion of the chair in the window, with respect to the vertical axis of the window, and thereby to minimize the danger of the hooks, which prevent backward tipping of the seat, be

coming disengaged from the sill.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing showing the preferred form of construction, and in which:

Fig. 1 is a perspective view of a preferred embodiment of the invention;

Fig. 2 is a fragmentary sectional View of a conventional window illustrating the invention arranged therein; and

Fig. 3 is a sectional view of my improved means to prevent lateral motion or side sway of the chair.

In the drawing, which illustrates a preferred and practical embodiment of the invention, 10 indicates generally my improved chair which includes a frame 11 on which is arranged a seat 12. The frame 11 includes side rails 13 which at their rear ends project upwardly above the seat to provide with cross pieces 14: a back rest or panel 15.

Braces 23 extend between the panel 15 and the rails 13, each of these braces 23 including an upright portion 16 secured to the corresponding rail 13.

Extending between the uprights l6 and the rails 13 are braces 17 each of which includes an offset portion 18 that is spaced from the adjacent upright 16. A brace 19 extends between each upright 16 and the seat 12.

Hook elements 20 are provided at the front ends of the rails 13 and these hook elements are joined by a brace 21. Depending from each of the rails 13 is a leg 22.

In Fig. 2 the manner of mounting the chair in a conventional type of window at is illustrated. The window 24 includes a vertical frame 10, a sill generally indicated at 25 and which includes the innermost part 26 and the outermost part 27. Sash guiding grooves are indicated at 28.

in use the chair is arranged in the window, as shown in Fig. 2, with the hook elements 20 engaging tlle innermost part 26 of the sill and the legs 22 resting upon the outermost sill part 27, the engagement of the hook elements with the part 26 preventing the chair and its occupant from tipping backwardly out of the window.

To prevent side sway or lateral motion of the chair in the window I provide improved means, generally indicated at 30, now to be described, and illustrated in section in Fig. 3. Said means includes devices that are provided in duplicate one at each side of the chair, and each device includes a cylinder or barrel 28 from the closed end 29 of which projects a boss 31 which is provided with an aperture 32 to receive a pintle or the like 43 that extends between and is mounted in an upright 16 and adjacent portion 18, thereby to pivot-ally mount the devices 30 at the sides of the chair.

Slidably mounted in each of the cylinders 28 is a plunger 34 which includes a piston 35 that is urged toward theopen end of the cylinder by a compression spring 36 in the cylinder, said open side being closed by a closure element 37 On each plunger 34 a head 38 is mounted in any suitable manner, as by a pin 39, and these heads 38 are adapted to fit into the sash grooves 28 and frictionally grip the window frame, against which they are urged by the springs 36.

When not in use the devices 30 will hang down at the inner sides of the uprights 16, and when the chair is placed in the window the devices 80 will be swung out into the position of Figs. 1 and 2, downward pressure being applied to compress the springs 36 and and thus force the heads 38 into the sash grooves 28, whereupon the heads 38 will grip the portions of the vertical frame 40 that form the sash grooves 28, thus preventing side sway or lateral movement of the chair and minimizing the resulting danger of the hooks 20 becoming disengaged from the sill part 26, which has been an objectionable feature of the prior art and a detriment to the use of this type of chair by workmen such, for example, as window cleaners, and others.

A bracket or arm 41 may be pivotally mounted on the panel 15, if desired, to support a pail 42 or other object.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is:

1. A window chair, a seat structure, means to secure the seat structure in a window against endwise displacement therefrom, means pivotally mounted on the seat structure for movement in a vertical plane paral lel to the axis of the window and extensible beyond the sides of the seat structure into gripping engagement with the window, the second-named means including window gripping members, and including spring means to urge said gripping members into gripping engagement with the window.

2. A window chair, a seat structure, means to secure the seat structure in a window against endwise movement therefrom, and means to prevent sidewise movement of the seat structure in the window, the second named means including elements pivotally mounted on the seat structure for movement in a plane vertical parallel to the axis of the window and extensible beyond the sides of the seat structure, members including portions movably mounted in said elements, and spring means in said elements to urge said members into gripping engagement with the window.

8. A window chair, a seat structure, means to secure the'seat structure in a window against endwise displacement, and means to prevent sidewise movement of the seat structure in the window, the secondnamed means including cylinders pivotally mounted on the seat structure for movement GEORGE SVEJDA, JR.
