This inventionrelates toy chairs and more particularly to a chair especially arranged to be mounted ona Window ledgeto support a person when washing the outer surface .of'a window.

It is among the objects ofthe invention to provide a chair whichcan be iirmly mounted on a window ledge toprov'ide a safe support for a person washing the'outsidejof the associated Window, which canbe yquickly 'and easily mounted `in a window by merely hooking it over the Window ledge, whichincludessafety features to prevent the chair from being dislodged even if the wood work of the Window ledge should' give Way, which is light in Weight so that it can be easily handled and provides a comfortable seat, which can be used as an ordinary'chair When not in use for washing Windows, and which is simple and durable in construction," economical to manufacture, and neat and attractive in appearance.

Other objects and advantageswill become apparent from a 'consideration of the following description and the appended claims in conjunction with the accompanying drawings wherein: n

Figure 1 is" an elevational View' of. an inner side of a Window Withachair, illustrative of the invention,` mountedor the Window ledge;

Figure 6 is ya cross sectional view on the line 6-5 of Figure, looking in the directions of the arrows; and Y Figure 7 is a perspective view of a hook assembly secured on the seat of the chair for engagement with the window ledge.

With continued reference tothe drawings, the Window opening is provided in a building Wall I and the window has a `frame including a yWindow ledge, generally indicated at 'I I, and upper and lower sashes I2 and I3 slidably mounted in the frame. The ledge I'I includes' an outwardly inclined sill I4 the outer edge of Which projects outwardly beyond thefouter side of the building Wall at thebottom ofthe window opening, a stool I extending along -theinne'r edge of the sill I4 and projecting inwardly of the inner side of the building wall anda trim strip I6 extending along the inner side 'of' the wall at' the lower-'side of the stool I5. f K

As window structures are old and Well known to the art and, as the chair of the present inventionv may be used-with. various types of Window l 3 Claims. (Cl. 155-131) 2 structures, a more detailed description of the window construction is considered unnecessary for the purposes ofthe present disclosure.Y

The chair comprises a rectangular seat Il which may be formed of any suitable material, such as Wood or metal, a back I8 extending at one edge along one edge of the seat and projecting substantially perpendicularly from one side oi the seat, front legs I9 and 26 extending from the opposite side of the seat at the cornersthereof re'- mote from the back I8 and rear legs 2| and 22 projecting from the side of the seat opposite the back I8 and at the corners of the seat adjacent the back.

In the arrangement illustratedy the front legs and the back are providedr from a single piece of metal tubing which is first bent adjacent its midlength location toya substantially U\shape, the intermediate portion 23 of which provides the top of the back and theside portions or legs of which provide the side members 24 and 25 of the back. This U,shapestructure,is then provided Withtwo substantially right4 angular bends Which are opposite in directionr and spacedapart so that one of the bends occurs at the proximalends of the back members 24 and ..25 and the other occurs at the proximal ends of the front legs I9 and 2D. This lprovides two rails 2B and 21 which are disposed substantially at right angles to the associated back side members" and front legs with ythe rail l2'5 connecting the proximal end of the front leg I9 to the proximal end of the back side member 24 and the rail z'lvpconnecting the proximal end 0f the front leg ZIJto the proximal end of the back side member25. The seat I1 rests at its opposite sides on the rails 26 and 2l` and is rmly secured to these rails bysuitable means, such as the clips 28 riveted or otherwise firmly secured to the under side of the seatand to the rails.

Each of the rearlegs 24| and 2.2 is separately provided and comprises a length of vmetal tubing bent to the form of areversed ,Sv. vEach of the rear legs has a portion extending lalong the co1'- responding rail and provided Withan elongated slot, as indicated at ,29, in Fgure, and each rail is provided with an aperture -registering with the slot.' A bolt or other suitable fastener 3U extends through the aperture ineach rail andthrough the slot in the corresponding rear leg to adjustably connect the rear legs to the associated rails, the leg 2I being eonnectedt'o'the rail 26 and the leg 22 being connected to the rail 21, as is particularly illustrated' in Figure 6;I I

A hook structure, generally designated at 3I and particularly illustrated in Figure 7, is rigidly secured to the under side of the seat I1 between the rails 2S and 21. This seat structure includes two lengths of suitable tubing, as designated at 32 and 33 disposed in spaced apart and substantially parallel relationship to each other. The member 32 has a straight shank portion 34 on one end of which is provided a curved hook formation 35 of substantially U-shape. The shank 34 is provided at spaced apart locations therealong with apertures 36 and 31 and is provided between these apertures with an elongated slot 38 which extends through the shank in a direction substantially7 perpendicular to that in which the apertures 36 and 31 extend therethrough.

The member 33 comprises a straight shank portion 40 and a U-shape hook formation 4I at one end of the shank portion. The shank portion 4D is provided with spaced apart apertures 42 and 43 and with an elongated slot 44 between the apertures and extending through the shank in a direction substantially perpendicular to that in which the aperturesextend through the shank.

A bar 45 extends transversely of the shank portions 34 and 4B near the ends of the latter remote from the hooks 35' and 4I and is provided with transverse grooves disposed one near each end thereofv which'grooves respectively receive the slotted portions of the shanks 34 and 4i). Screws 46 and 41 extend longitudinally of the bar from the respectively opposite ends thereof and extend through the slots in the corresponding shanks to adjustably secure the members 32 and 33 to the bar. The surface of the bar 45 remote from the seat I1 is bevelled to fit the outwardly sloped or inclined window sill I4.

The members 32 and 33' are rigidly secured to the under side of the seat I1 by suitable fasteners extending through the apertures 35, 31, 42 and 43 so that the shank portions of these members are substantially parallel to the rails 2B and 21, the member 32 being disposed adjacent the rail 23 and the member 3'3 adjacent the rail 21, and so that the hook formations 35 and 4I extend perpendicularly away from the seat with their open ends facing the rear legs of the chair.

With this arrangement, when the hook formations 35 and 4I are engaged over the inner edge of the window stool I5, as is particularly illustrated in Figure 2, the rails 26 and 21 extend across the window ledge assembly and the inwardly curved rear legs 2I and 22 bear near their lower ends, that is their ends remote from seat I1, against the outer side of the building wall below the window opening therein. This arrangement rigidly supports the chair on the window ledge so that a person may safely sit in the chair while washing the outer side of the window.

The rear legs may be adjusted inwardly and outwardly relative to the seat to condition the chair to the width of a particular window ledge and the bar 45 may be adjusted along the shank portions of the hook members 32 and 33 so that this bar will rest at the proper position on the upper surface of the sloped window sill.

In order to provide an additional factor of safety an elongated tubular arm 50 is pivotally connected at one end to the leg I9 adjacent the seat I1 by a hinge 5I the axis of which is substantially parallel to the front leg I 9 and a similar arm 52 is connected to the front leg 2U by an associated hinge 53.

When the chair has been placed in the window opening, as illustrated in Figure 2, the front legs will be spaced inwardly from the trim strip I6 which extends along the inner side of the building wall below the Window stool I5. The distal ends of the arms 50 and 52 may be brought into engagement with this trim strip to hold the chair against dislodgment in the event the Wood work including the window stool I5 and the ledge III'` should give way under the Weight of a. person seated in the chair. As the trim strip is disposed directly against the building'wall, the arms will hold the chair'against a serious displacement even though the window stool engaged by the hooks should be disrupted.

In the case of wide Windows, the chair can be easily slid along the window ledge to render the entire outer surface of the window easily accessible and, if desired, suitable hooks or other attachments may be provided on the chair for supporting pails and other implements used in washing windows. i

.The invention may be embodied in other specie forms without departing from the spirit or essential characteristics thereof. The present embodiment is` therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended. claims rather than by the foregoing description, and all' changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
