COLLAPSIBLE WINDOW CHAIR.

Application filed December 22, 1923.

To all whom it may concern. v

Be it known that I, MICHAELIS Scion- MANN, a citizen of the United States, and a resident of New York, borough of Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in a Collapsible Window Chair, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a class of devices adapted to be used for supporting persons on the exterior of winows.

My invention has for its object primarily to provide a device designed to be employed to support persons on the exterior of the windows of buildings and other structures for accomplishing without the danger of falling various kinds of work, such as cleaning windows, glazing, painting, hanging and taking down awnings and for other general uses, and which is made preferably in the form of a chair serving to overcome the hesitancy of timid persons against working exteriorly of windows, The chair is further adapted to be collapsed and removed from the window for occupying a limited space when not in use. The invention consists es sentially of a seat or platform for being dis posed outwardly of a window upon the sill of its frame for accommodating a person thereon either in a sitting or standing posture on the exterior of the window, and serving to prevent the occupant from liability of falling from the seat, a back is flexibly connected to the outer part of the seat. The back may be swung upwardly and clownwardly from the seat so that the device may be packed in a limited space when not in use, and means is provided on the seat for engaging the inner edge of the sill to removably fasten the seat to the window frame.

A further object of the invention is to provide a window chair of a simple, efficient and durable construction which may be made of suitable material in any appropriate size and shape.

With these and other objects in view, the invention will be hereinafter more full explained with reference to the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be ointed out in the claim at the end of the escription.

Serial No. 682,179.

In the drawing, Figure 1 is a fragmentary view showing an inner elevation of a window with one form of my improved collapsible chair applied thereto.

Fig. 2 is a side elevation of the chair, and

Fig. 3 is a front elevation of the chair showing the seat folded upon the back of the chair.

The device or chair has a seat or platform 10 which may be of any appropriate size and shape, though the form of the seat illustrated is substantially rectangular and of a size to permit of being removably disposed from the inner to the exterior of the win dow, as 11, of a building or other structure so as to lie upon the sill, as 12, between the stiles, as 13, 14:, of the frame of the window as well as protruding a sufficient distance to allow a person to be accommodated on the seat in a standing or sitting posture exteriorly of the window. The seat is also preferably adapted to be arranged so that its inner edge will be disposed on the usual protruding inner edge of the sill 12 of the window and so that the central part of the seat will be disposed above the lower guide rail, as 15, of the sash 16 of the window.

To the outer edge of the seat or platform 10 may be hinged or flexibly connected, at 17, the lower edge of a back, as 18, for serving to protect a person on the seat against liability of falling, and this back is pref erably substantially rectangular as well as adapted to be swung upwardly and down wardly from the seat toward and from the exterior of the window. The chair may thereby be collapsed for occupying a limited space when not applied to a window, and the seat and back may be made of wood, fibre, metal or other suitable material.

In order to limit the upward or outward movement of the back 18 from the seat 10; that is, to prevent the back from moving beyond an approximately right angular position relative to the seat when swung upwardly, I provide flexible connections, as 19 and 20. The flexible connections 19, 20 may be of any suitable formations so that they will freely yield or bend when the seat and back are folded together, though each of these flexible connections shown are in the form of a pair of chains, as 21, 21 and 22,

chains 21. 21 are held, at 24, to parts of the back 18 in proximity to the hinge 17. @ne of the ends of the chains 22, 22" of the flexible connection 20 is attached, at 25, and 25 to the ends of a bar, as 26, disposed across and below the edge of the seat opposite to the back 18, and the other ends of the chains 22, 22 are fastened, at 27, 27, to the upper parts of the side edges of the back. The back will thereby beheld against liability of movement beyond its right angular position when swung upwardly from the seat for protecting the occupant from danger of falling, and the back also tends to over come the hesitaney of timid persons against working eXteriorly of windows for cleaning the panes of glass or glazing or painting or for accomplishing other work.

Under the ends of the inner edge of the seat 10 are corresponding hoolesliaped members or catches 28, 29 adapted to engage the protruding inner edge of the sill 12 for movably fastening the seat to the frame of the window. Under the seat 10 below the back 18 may be similar substantially U-shaped members or supports 30, 31 for serving as means to support the seat 10 at a determined elevation above the outer part of the sill of the window frame. The hookshaped member 28' and the U-shaped member or support 30 may be integrally formed from a metal bar 32 which is fastened on the underside of one of the side edge parts of the seat. One of the ends of the bar 32 is curved downwardly to provide the hook member 28, and the other end of the bar is bent to provide the U-shaped support 30, while the central part of the bar may be bent to provide, a recess, as 33, for accommodating the cross rail 15 of the sill of the window frame. The hook-shaped member 29 and the U-shaped member or support 31 may also beintegrally formed from a pliable metal bar 34 which is secured on the underside of the other side edge part of the seat. One of the end parts of this bar 34 is curved downwardly to provide the hook member 29, and the other end part of the bar is bent to provide the ltsliaped support 31. The central part of the bar 34 bent to provide a recess, as which is in register with the recess 33 to accommodate the cross rail 15 of the sill of the window frame. When the chair fastened to the window frame by engaging the inner edge of the sill with the hook-shaped members or catches'28, 29, the seat 10 and back 18 will be disposed outwardly of the window, and the bar v26 extends across the free end parts of the hook-shaped members in spaced rela tion to the seat for also engaging the underside of the inner edge of the sill of the window frame. The fastening means 25, 25 of the chains 22, 22 may be in the forms of bolts or screws for also securing the bar 26 to the free end parts of the hook-shaped members, and by attaching the chains to the bar and hook-shaped members the pres sure of the occupant of the chair against the back will serve to pull the chains for causing the hook-shaped members and the cross-bar 26 to tightly grip the sill of the window frame. Between the seat and the central parts of the bars 32 and 34 may be two cross-bars, as 36, 37, for bracing the bars 32 and 34, and the bars 36, 37 may be fastened to the seat 10 by removable screws or bolts to allow the bars 36, 37 to be suitably spaced from each other as occasion may require.

In the foregoing description, I have em bodied the preferred form of my invention, but I do not wish to be understood as linr iting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention. therefore, I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent The combination with a collapsible window chair having a substantially rectangula r seat with a back hinged thereto, of two spaced parallel. bars fastened on the underside of the seat and both bars having ou of their corresponding ends bent to provide yielding depending hooks for being disposed over the inner edge of the sill of the window. said bars having their other ends bent in approximately ti -shapes to provide sup ports for elevatingthe seat above the sill and the bars having their central parts also bent to provide recesses for accommodating the rail of the window sill, a cross-bar connecting' the free ends of the hooks, and chains having their ends attached to upper parts of the back and to the free end parts of the said hooks for limiting the upward movement of the back and to force the free ends of the hooks toward the seatwhen the back is under upward pressure.

This specification signed and witnessed this 21st day of December. A. 1923.
