A sliding screen door security kit comprising a sliding screen door, a security grille for mounting on a sliding screen door, a key-operated locking unit for attachment to said sliding screen door capable of preventing the sliding screen door from sliding and from being lifted off of its track, a sliding flat bolt locking unit comprising a fixed flat bolt and a keeper which slidably engages said bolt, which when engaged is capable of preventing the sliding door from being lifted off of its track, and mounting hardware therefor.
A sliding door security system to be used in a building in combination with a static panel, a sliding screen door and a sliding glass door comprising a sliding screen door and a sliding glass door, each door sliding in an upper track and a lower threshold track, the sliding screen door having a rear surface and a front surface, as well as a rear frame border and front frame border both of which are around the perimeter of the sliding screen door;
- the rear surface of the sliding screen door facing the sliding glass door;
- said front frame border around the perimeter of said sliding screen door being provided with a surface-mounted and attached security grille, wherein the mounted and attached security grille slides along with the sliding screen door, provides security to the interior of a building, as well as allowing air to readily circulate to the interior of the building to which the sliding screen door is attached, one of said sliding glass door and said stationary panel having a flat bolt and the other of said sliding screen door and said stationary panel having a keeper for engaging said flat bolt when the sliding screen door is fully closed to prevent removal of said sliding screen door.
In a building having a sliding door structure for a patio or balcony, wherein the structure includes a frame, a stationary glass panel, a sliding glass door, and a sliding screen door, respectively, the improvement comprising a security grille attached to the sliding screen door and sliding therewith, a key-operated lock between the sliding screen door and the frame and accessible internally of the building, such that even if the sliding screen door with its security grille attached thereto is penetrated by an intruder, the lock cannot be unlocked by the intruder to open the sliding screen door and further the sliding glass door may be opened at any desired distance from the frame, thereby adjusting the degree of desired ventilation while assuring security for the occupants of the building, one of said sliding glass door and said stationary glass panel having a flat bolt and the other of said sliding screen door and said stationary glass panel having a keeper for engaging said flat bolt when the sliding screen door is fully closed to prevent removal of said sliding screen door.
In a building having a sliding door structure for a patio or balcony, wherein the structure includes a frame, a stationary glass panel, a sliding glass door, and a sliding screen door, respectively, the improvement comprising a security grille attached to the sliding screen door and sliding therewith, a key-operated lock between the sliding screen door and the frame and accessible internally of the building, in addition attached to the stationary glass panel and the sliding screen door are a stationary horizontal flat bolt and keeper, such that when the sliding screen door is closed, the stationary horizontal flat bolt will lock into its keeper and with the key-operated lock fastened the sliding screen door cannot be lifted out of its track.
In a building having a sliding door structure for a patio or balcony, wherein the structure includes a frame, a stationary glass panel, a sliding glass door, and a sliding screen door, respectively, the improvement comprising a security system in which a security grille is attached to the inside surface of the stationary glass panel and with a second security grille attached to the outside of the sliding screen door and sliding therewith, a key-operated lock between the sliding screen door and the frame and accessible internally of the building, and attached to the stationary glass panel and the sliding glass door are a stationary horizontal bolt and keeper, such that when the sliding screen door is closed, the stationary horizontal flat bolt will lock into its keeper and with the key-operated lock fastened, the sliding screen door cannot be lifted out of its track and further even if the sliding screen door with its security grille attached thereto is penetrated by an intruder, the lock cannot be unlocked by the intruder to open the sliding screen door.
A building having a sliding door structure for a patio or balcony, wherein the structure includes a frame, a stationary glass panel, a sliding glass door, and a sliding screen door, respectively, the sliding doors having respective tracks and further having respective open and closed positions, the improvement comprising a security grille attached to the sliding screen door and sliding therewith, such that the sliding glass door may be opened at any desired distance from the frame while the sliding screen door is in the closed position thereof, thereby adjusting the degree of desired ventilation while assuring security for the occupants of the building, a first lock installed between the sliding screen door and the frame and accessible internally of the building, the first lock including a first bolt movable along a substantially vertical axis, thereby precluding horizontal movement of the sliding screen door from the closed position thereof, a second lock installed between the sliding screen door and the stationary glass panel, the second lock including a second bolt movable along a substantially horizontal axis with the movement of the sliding screen door and engaging a keeper on said stationary glass panel, thereby precluding a substantial vertical movement of the sliding screen door out of the respective track therefor, such the first and second locks, respectively, preclude substantial movement of the sliding screen door and the security grill attached thereto in the vertical plane thereof.
