' A. GIRARDI CHAIR FOR WIfiDOW CLEANING Filed Feb. 27, 1926 2 Sheets-Sheet 1 INVENTOR ANGELO fi/RARDI' BY fill/1M ATTORNEYS Patented Nov. 30, 1926.
ANGELO GIRARDI, OF UNION CITY, NEW JERSEY.
CHAIR FOR WINDOW) CLEANING.
Application filed February My invention relatesv broadly to chairs commonly employed by window cleaners while engaged in the1r work.
The object of my invention is to provide a strong portable chair which may be economically manufactured, conveniently folded for transportation, and can be securely locked in the window.
These and other objects and the means by which I accomplish them will appear in the following description of the mode in which I at present prefer to carry the invention into practice. The various features of the invention will then be pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this specification in which like parts are designated by the same numerals in all the figures.
Figure 1 is a. longitudinal sectional elevation taken on line 11 of Figure 2 showing the present preferred form of my improved chair secured in a window.
Figure 2 is a plan view of the same.
Figure 3 is a front elevation of the same.
Numeral 5 represents the ordinary window frame or casing set in a wall 6 and having a sill 7 and bottom rail 8.
9 designates the back of the chair proper preferably formed of metal tubing, though it may be formed of solid rods or any other suitable material. The side members of the back 9 are extended downward and carried forward as shown in Figure 1 so that the bearings 10 on the lower ends of said side members abut against wall 6. In this instance, back 9 is preferably strengthened by cross-braces 11 of any suitable material and construction.
The seat of the chair is designated by 12, is hinged to back 9 in a manner which will hereinafter be described. and is preferably formed by stamping or other suitable means from a single sheet of metal stock. The sides of the seat are preferably bent up to form flanges 13 which are out out as at 1 1 to form longitudinal guides terminating in stops 30 for arms pivoted at 16 to the front of the seat 12.
In use the arms 15 are swung outward through the cut-out arm guides 14 and are then adapted to bear against the window frame 5 and so look the chair securely in place in the window frame. I prefer to make these arms of stock having a circular Serial no. 91,193.
cross section to provide a better bearing surface against the frame 5, but it is obvious that other forms of arms will be equally as suitable. The outer ends of the arms are extended forward to form guide pieces 16 which serve to guide and steady the arms 15 in the guides 14 of flanges 13. At the forward ends of guide pieces 16 are preferably provided upturned handles 17 serving also as stops which limit the inward movement of the arms 15 and also afford hand holds, for the window-cleaner in pulling out the arms when the arms are in the position shown in dot and dash lines in Figure 2.
The chair is adapted for use in various sized windows, and to prevent the chair from moving laterally so as to displace one of the arms from its engagement when used in a large window frame, I prefer to provide laterally extending frames 18 on the arms 15. These frames, as is obvious, prevent any undue lateral displacement of the chair and also serve as additional guides for the arms 15 in their movement in the guides 14 Extending downward from said chair, and preferably integral therewith, is bearing 19 adapted to bear against the outside of wall 6 and substantially in the normal vertical plane of the lower bearing ends 10 of back 9. The provision of this bearing surface 19 and its alignment with bearing ends 10 serve to prevent the chair from sliding forward on the window sill and also steady the chair and secure it from moving.
To hinge seat 12 to back 9, I secure said seat as by riveting at 20 to angle plates 21 and then pivotally securing by pin 22 the seat and angle plates attached thereto to wing plates 23 which, in this instance, are rigidly secured to the side members of the back 9 by folding one end of said wings around the respective side members and then welding or otherwise rigidly securing the wing plates to said side members. To guide the seat 12 in its movement about pivots 22, I prefer to provide pins 24 secured to flanges 13 and angle plates 21 which are adapted to ride in arcuate slots 25 provided in wing plat-es 23. By so hinging seat 12 to back 9, the chair may be folded as shown in Figure 1, the seat occupying the position indicated in dot and dash lines.
It will thus be seen that I have provided a strong and economically-manufactured window-cleaners chair which has a minimum of parts, may be folded for transportation, and is readily portable.
It is evident that many changes may be made in the specific construction and arrangement described without departing from the boundaries of my invention as defined by the following claims.
I claim as my invention 1. A foldingchair for Window cleaning and the like comprising a back, a seat hinged to said back, arms pivoted to the front of said seat to swing upward with said seat against the back and to swing outwardly and forwardly and bear against the inside of a window frame, longitudinal arm guides in the sides of the seat, and stops for the arms on the inner ends of said arm guides.
2. A folding chair for window cleaning and the like comprising a back, a seat hinged to said back, arms pivoted to the front of said seat to swing upward with said seat against the back and to swing outwardly and forwardly and bear against the inside of a window frame, longitudinal arm guides in the sides of the seat, arm stops on the ends of the guides, and frames on the inside of the arms to work in said guides and limit the lateral displacement of the chair.
In testimony whereof I afiix my signature.
ANGELO GIRARDI.
