UNITED STATES PATENTS 2,482,340 9/1949 Holmsten 292/346 2 Claims, 3 Drawing Figures CRASH BAR BRACKET ASSEMBLY This invention relates to security, more particularly to devices for preventing illegal entry.

A principal object of this invention is to provide an enclosing structure at the end of a crash bar. This structure is permanently attached to the door covering that portion of the bar but does not interfere with the normal intended use of the crash bar.

Another object of this invention is to provide a device that is quick and easy to install, is reliable for the life of the crash bar and low incost.

These and other objects will be readily evident upon a study of the following specification together with the accompanying drawing wherein:

FIG. 1 is a front view of the device shown installed on a crash bar;

FIG. 2 is a front view of the device as purchased;

FIG. 3 is a side view thereof.

This invention is designed to stop and prevent illegal entry through any set of double doors provided with crash bars. Such bars are used in schools, public buildings and other structures where larger groups of people congregate. There has developed a great need for some type of prevention to illegal entry by vandals and burglars. The financial loss to schools and other public buildings has not stimulated serious consideration of the inherent failure in security where crash bars are used. This invention seeks to make illegal entrance impossible without interfering in any way with fire safety regulations.

Referring to FIG. 1, a crash bar is shown installed on an emergency door of a double door 15, 16. As normally installed, the intruder wedges an implement at the interface 12 between doors 15 and 16 and reaching bent portion 12a of crash bar 10, moves the bar sufto bent portion 12a of bar 12.

The device 17 shows a piece of steel angle 18 having a facing surface 19 and a side surface 20. Angle material 18 is bent so that there is a straight portion 21 and an angularly disposed portion 22 conforming to the angle that bend makes with crash bar 12. Bend 21 has affixed thereto or integrally a bracket 23 having a contour as seen in FIG. 3 and terminating in screw attachment holes 24. Angle portion 22 has affixed thereto or integrally a bracket 25 having screw attachment holes 26. The parts having screw holes 24 and 26 are in one plane as seen in FIG. 3 for attachment to an emergency door. Such attachment may now be examined in FIG. 1 where holes 24 and 26 show screws 27 and 28 respectively.

It may now be seen and appreciated that side portion 20 of angle 18 covers bent portion 12a of crash bar 10, effectually so as to prevent the passage of an implement through interface 11 and over the top portion 12a with the intention of unlocking the door.

What I claim is:

l. A security device for use on a crash bar comprising a means for enclosing the end of said crash bar at the front and side thereof without interference to the intended function thereof for the purpose of preventing the use of an implement, passed through the interface of an emergency double door, to manipulate said crash bar from outside of said door.

2. A device of the type described in claim 1, wherein a piece of angle iron or the like is bent to the contour of the end of said crash bar, said angle iron provided with means for permanent attachment to said emergency door, one face of said angle iron disposed between said bent portion of said crash bar and said interface, the other face of said angle iron disposed in front of said bent portion of said crash bar, and installed without interference to normal operation of said crash bar.

Claims (2)

1. A security device for use on a crash bar comprising a means for enclosing the end of said crash bar at the front and side thereof without interference to the intended function thereof for the purpose of preventing the use of an implement, passed through the interface of an emergency double door, to manipulate said crash bar from outside of said door.

2. A device of the tYpe described in claim 1, wherein a piece of angle iron or the like is bent to the contour of the end of said crash bar, said angle iron provided with means for permanent attachment to said emergency door, one face of said angle iron disposed between said bent portion of said crash bar and said interface, the other face of said angle iron disposed in front of said bent portion of said crash bar, and installed without interference to normal operation of said crash bar.
