Application January 30, 1956, Serial No. 562,119
'2 Claims. (Cl. 254-129) This invention relates to a new and useful improvement in a window opener, and more particularly to the sash of a window that has become stuck to the window frame and cannot be opened by manual means.
It is well known that when houses and buildings are decorated, the windows, when painted, generally become stuck by the paint and tools are generally required to open them. When such devices are used, the woodwork of the window quite frequently becomes scarred in the process of opening it.
One of the objects of this invention is the provision of a device adapted to open a stuck window.
Another object of this invention is the provision of a window opener so constructed that it will not mar or deface a window when it is used to open such window.
Other objects and features will more fully appear from the following description and accompanying drawings, in which:
Fig. l is an elevational of a window showing the application of the invention;
Fig. 2 is a sectional side view of a window and the device applied thereto, and taken along lines 22 of Fig. 1;
Fig. 3 is a view in side elevation of a detail of the invention with one buffer, cushion or pad in section;
Fig. 4 is a sectional view taken along lines 4-4 of Pi 3, and
Fig. is a sectional view taken along lines 5-5 of Fig. 4.
Referring more particularly to the drawings a stanchion or bar 1 has a resilient cushion or rubber pad 2 secured thereto in order to prevent the marring or scarring of an object it is adapted to rest upon. A carriage 3 is provided with an aperture 4 through which bar 1 passes in slidable fashion.
A channel 5 is adapted to accommodate a lever 6 mounted in pivotal fashion upon an axle or pin 7 disposed in the sides of said channel. The lever 6 has one of its ends 8 angular in shape and is adapted to accommodate a resilient tip or cushion 9 to prevent the marring of an object when force is applied by said lever against said object.
A leg 10 on said carriage has an orifice 11 therein to accommodate a hook 12. End 13 of said hook constitutes an eye and is adapted to engage bar 1 in slidable fashion. Shank 14 of the hook is smaller in diameter than orifice 11 and a wing-nut 15 is mounted in threadable fashion on end 16 of the hook and rests upon a washer 17 that engages leg 10.
It is thought obvious that when the carriage is actuated or adjusted upwardly or downwardly towards pad 2, the hook will impinge upon or grip the bar 1 in an angular fashion and thereby prevent vertical displacement with respect to the carriage and bar, and thereby lock the former to the latter.
A window 18 consists of a casement or frame 19 provided with sashes 20 and 21 that are adapted to respectively move in tracks 22 and 23, all of which is wellknown in the art.
The device functions as follows: Assume that sash 20 is stuck or secured to frame 19 by paint or other adhesive material, then bar 1 has its padded end resting upon frame 19, while the padded end of lever 6 rests or engages sash 20. Hook 12 then locks the carriage in a suitable position for operation. Lever 6 is then forced downwardly thereby applying force to the sash and causing it to move to an open position.
Of course, the aperture through which the stanchion or bar passes is greater in diameter than the latter and when force is applied to the lever it also tends to move the carriage in angular fashion against the stanchion or bar and this also tends to lock the carriage thereto.
it is also to be understood that the device may be applied in transverse fashion to a window.
Having described this invention, what is claimed is:
1. In a window opener of the kind described, said opener comprising a bar having a carriage slidably movable and adjustable mounted thereon, said carriage having an apertured portion therein, said aperture of said apertured portion comprising transverse dimensions larger than the transverse dimensions of said bar, thereby providing for limited tilting movement of said carriage on said bar for gripping action of said carriage on said bar in any adjusted position of said carriage on said bar, said carriage having walls on one side thereof defining a channel, a lever, said lever being pivoted intermediate its ends in said channel to the walls thereof, said lever havin a power arm and a weight arm, said Weight arm having on its free end a suitable pad to prevent marring of a widow sash, said carriage having on the outermost portion thereof a leg projecting therefrom, said leg having an aperture therein transversely thereof, the axis of said aperture being at right angles to the axis of said bar, a bolt, said bolt having one end thereof provided with a screw thread and a threaded nut thereon, said bolt having its other end provided with an embracing portion slidably embracing said bar, said bolt loosely passing through said leg whereby said carriage may be forcibly tilted into gripping action with said bar to maintain said carriage in any suitably adjusted position on said bar, one end of said bar having a pad thereon for nonmarring contact with a window frame.
2. In a window opener of the kind described, said opener comprising a bar, a carriage mounted in slidable fashion upon said bar, a lever pivotally mounted on said carriage and having a portion thereof of greater length from said pivot than the remaining portion; a hook having one of its ends engaging said carriage and the other of its ends mounted about said bar in slidable fashion, said carriage and hook adapted to grip said bar and prevent vertical displacement between said bar, carriage and hook upon suitable and adequate lever force.
