Embodiment Construction

[0019] Figure 1 is used to illustrate the surroundings of the present invention, showing a passageway, such as a window 12, in a wall 10 of a building, with protective strips or gratings mounted on the outer surface 16 of the wall 10. Grid 14. The window 12 is slidable between open and closed positions for ventilation purposes, while also providing an emergency passage for entry and exit. The guard strip 14 is mounted on the wall surface 16 by hinges 18 and locked by a single opening device 20 according to the invention. An opening device 20 is attached to the guard strip on the opposite side of the hinge 18, so that once the device 20 is opened, the guard strip 14 can be swung aside of the hinge 18, thereby allowing emergency access to the building. In some installations it may be preferable to omit the hinge 18 and use two or more opening devices according to the invention to connect the protective strip to the wall.

Abstract

A lock mechanism for releasably locking a security bar (14) over an opening (12) through a wall (10) includes a housing (30, 32, 60) for mounting to the wall adjacent the opening. An engagement mechanism (28) is coupled to the security bar (14). A keeper member (26) in the housing is movable to selectively engage a lock surface (102) on the engagement mechanism to restrain the engagement mechanism from movement relative to the housing; the engagement mechanism being allowed to move unrestrained relative to the housing when the keeper member does not engage the lock surface. A manually-operable latch mechanism in the housing moves the keeper member out of engagement with the lock surface. A receiver tube (70) forms a passage between the housing and the outside surface of the wall, with the engagement mechanism (28) extending through the receiver tube without engaging the receiver tube so that the engagement mechanism and security bar are laterally moveable due to settling of the structure of which the wall is a part. An optional slide mechanism (22) is operable by an external operator (120), such as a thermal sensor, smoke detector or wireless receiver, to operate the latch mechanism (24).

Description

technical field [0001] The present invention relates to an opening device for a protection strip, and more particularly to such an opening device which allows the protection strip to be opened from the inside of the room and allows the protection strip caused by the subsidence of the building to be opened relative to the device. A fixed wall moves slightly. Background technique [0002] In recent years, people have become more and more concerned about the safety of themselves and their property. This concern has led to an increase in the installation of guard strips or gratings on passages, such as doors and windows, of dwellings or other buildings. In the usual way of installation, the protective strip is installed directly on the surface of the building's outer wall to prevent entry from the passageway. [0003] At the same time, people are also more and more concerned that in the event of an accident such as a fire, the protective strip will prevent the occupants from p...
