Slidable deadbolt security device for sliding doors and windows enabling selective locking thereof in closed or partially open position
First Claim
1. A slidable deadbolt security device for installation in association with horizontally slidable door assemblies and horizontally slidable window assemblies, said slidable deadbolt security device comprising:
- a) an elongated body having first, second, top and bottom sides and front and back ends, said elongated body having at least one slot that penetrates said first and second sides and extends longitudinally of said body from adjacent said front end to adjacent said back end; and
b) a slidable deadbolt assembly mounted in said at least one elongated slot and digitally deployable or retractible to selectively engage or disengage, respectively, an associated slidable door or window to limit to at most the length of said slot the degree to which said slidable door or slidable window may be partially opened and which precludes lifting of said slidable door or slidable window when said slidable deadbolt is in engaged condition, while enabling unrestricted slidability of said associated door or window when said slidable deadbolt is in disengaged retracted condition.

Abstract
Presented is a slidable deadbolt security device designed for installation with a sliding glass door or sliding glass window. The slidable deadbolt security device is fastened to the threshold in association with the leading edge of the fixed door portion of a slidable door assembly. A deadbolt is manipulable to engage or disengage the sliding door portion. The relationship of the slidable deadbolt and the sliding door frame is such that the deadbolt cannot be disengaged from the sliding door frame unless the sliding door is completely closed. In an aspect of the invention relating to sliding glass windows, the slidable deadbolt is slidably mounted on the windowsill adjacent the leading edge of the fixed window portion of the window assembly and spaced laterally from the fixed window frame to enable the slidable window portion to move therebetween. An aperture in the frame of the sliding glass window, or in a flanged bracket attached to the trailing edge of the sliding glass window portion, receives the deadbolt, permitting the window to be partially opened a predetermined amount, but prevents further opening, prevents manipulation of the deadbolt to release its engagement with the window frame or flange, and prevents lifting of the slidable window from its track.

18. In combination, a slidable window assembly including a fixed window pane and a horizontally slidable window pane having a rear edge arranged in juxtaposed parallelism to said fixed window pane and normally slidable in relation thereto, said slidable window pane having an apertured bracket attached to said rear edge;
- and a slidable deadbolt assembly operatively associated adjacent the rear edge of said slidable window pane and including a slidable deadbolt selectively deployable to engage the aperture in said bracket, said slidable deadbolt when engaged with said bracket being slidable with said bracket and window to restrict the degree of movement of said slidable window pane between completely closed and partially open conditions and retractable to disengage said apertured bracket to enable unrestricted movement of said slidable window pane and bracket.

19. As an article of manufacture:
-
a) an elongated body having first, second, top and bottom sides and front and back ends, at least one elongated slot that penetrates said first and second sides and is spaced generally medianly between said top and bottom sides and extends longitudinally of said body from adjacent said front end to adjacent said back end, said at least one elongated slot at its end adjacent said front end being enlarged to provide a generally circular aperture having a diameter greater than the width of said at least one elongated slot; and b) a slidable deadbolt assembly mounted in said at least one elongated slot in said enlarged circular aperture associated with the front end of said elongated body, said slidable deadbolt assembly comprising an elongated shaft having a pull head at one end, a deadbolt head at the opposite end, an intermediate integral radial flange spaced a predetermined distance from said pull head and having a diameter greater than the width of said slot but smaller than the diameter of said enlarged circular aperture, spring means interposed between said deadbolt head and said first side of said elongated body and normally resiliently biasing said deadbolt head away from said first side, whereby said slidable deadbolt assembly may be selectively translated to compress said spring means and to position said integral radial flange so that it resiliently impinges on the second side of said elongated body and said deadbolt head is retracted toward said first side of said elongated body and enabling said retracted slidable deadbolt assembly to move longitudinally along said at least one slot.
