Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a security door used at a counter of a financial institution such as a bank.

Even if a financial institution closes its shutters at closing, the tellers are only separated by counters, and once inside, you can get a panoramic view and can freely go around the counters.
Additionally, there were disadvantages in terms of crime prevention, such as lack of protection for staff and others in the event of a burglar breaking into the counter since there was no partition between the counters.

The present invention has been made to solve the above problems, and therefore, an object of the present invention is to provide a security door suitable for crime prevention in financial institutions.

The security door according to the present invention is characterized in that it is installed at a counter in a bank or the like, so that the counter can be closed at the time of closing or in an emergency. An example will be explained.

Figures 1 and 2 show counters of financial institutions such as banks, and in the illustrated example, three counters 2 are installed in line with a door 1 on one side, and each counter 2
is equipped with a security door 10 according to the present invention. This security door 10 separates the inside and outside with the counter 3 as a border, and is therefore provided at each counter.

As shown in FIGS. 3 to 5, this security door 10 includes a vertically movable door 11 held below the surface of the counter 3, and pillars 12 located on both sides of the door to guide its vertical movement. , a drive 13 for raising the door 11, a latch 14 for holding the door 11 in its raised position, and an actuation member 15 for unlocking the latch 14. The door 11 is made of a strong board 11', such as a steel board or a bulletproof board. Each pillar 12 is the fifth
As can be seen, it is preferably formed by a profile with a concave cross-section that can loosely accommodate the edge of the door. In this embodiment, the drive device 13 is the door 1.
Commercially available spring balancers 13a installed at the upper ends of both sides of the door 11 are used, and wires 16 connect the spring balancers to appropriate positions on each side of the door 11. In the figure, 16a is a wire stopper. Shoes 17 are provided on both sides of the side edges of the door 11, and these portions abut against the corresponding surfaces of the support columns 12 to properly guide the vertical movement of the door 11. The latch 14 is preferably an electric lock with an electromagnetically actuated catch. In the example shown, a spring balancer is used, so a latch 14a is used to hold the door 11 below the surface of the counter 3. 15 is an operating member such as a switch for unlocking the lower latch 14a. In this case, if the latch is provided near the counter 3, one latch can serve as both the upper and lower latches. The latch may be of any suitable type, and the example shown in FIG. 6 is of the retractable type, so that the lowering of the strike 18 at the lower end of the door 11 retracts the latch 14' and engages the hole 11a. It's summery.

Preferably, as seen in FIG.
A cushioning material 21 is attached to the lower surface of the horizontal member 20 directly above the horizontal member 20 . Furthermore, a flat plate 22 made of an appropriate material that matches the surface of the counter 3 is installed at the top of the door 11. This configuration allows the top of the door to be used as an effective surface of the counter 3.

When this security door is opened, the door 11 is held under the surface of the counter 3 by a latch 14a, as shown in FIGS. 3 and 4, but when the door is closed, the latch 14a is released by operating the operating member 15. After locking, the door 11 is pulled up by the spring balancer 13a, and the window 2 is closed. Furthermore, in an emergency such as when a robbery occurs, the counter 2 can be closed in the same way by touching the operating member 15. To open the window 2, the latch 14 may be unlocked and the door 11 may be lowered manually. Alternatively, the door may be lowered automatically.

Although a pair of spring balancers 13a are used in the above embodiment, it is possible to use only one spring balancer depending on the relationship between the force of the spring balancer and the weight of the door. Further, the lifting of the door is not necessarily limited to a spring balancer. For example, as shown in FIGS. 7 and 8, a weight 13b that is heavier than the door 11 may be used. In this case, both ends of the weight and the door 11 The lower part of the chain 24 is connected to a chain wheel 23. If the chain wheels 23 on both sides are connected by a common shaft 25, they can be moved up and down while maintaining a horizontal state. Roller 26 is used instead of shoe 17 to guide the door.
may also be used. Furthermore, this drive 13 can also be an electric motor or a pneumatic or hydraulic cylinder.

As described above, according to the present invention, in an emergency or when closing time, the door below the surface of the counter can be raised to close the counter, so even if an intruder enters the building from the outside, he or she can cross the counter and close the counter. This makes a significant contribution to crime prevention as it is impossible to enter inside the building. Moreover, it has smoke and flame retardant effects, and has disaster prevention benefits. Furthermore, the top of the door can be used effectively.
