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 when it closes, the boundaries between the tellers are only separated by counters, and if you go inside, you can get a panoramic view and can freely go around the counters. In addition, 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 because there was nothing to separate the counter.

The present invention has been made to solve the above problems, and 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 when the store opens or in an emergency. An example will be explained.

Figures 1 and 2 show the counters of financial institutions such as banks, and in the illustrated example, a door (1) [three windows 12 in a row] is installed on one side, and each window (2 windows) is installed on one side. ) is equipped with a security door (10) according to the present invention. This security door (
10) is provided at each counter because it separates the interior and exterior using the counter (3) as a boundary.

As shown in Figures 3 to 5, this security door (10
) raises the door ttU with the vertically movable door (II) held below the surface of the counter (3), the pillars f12) located on both sides of the door and guiding its vertical movement. It consists of a drive device (13+) and an actuating member a!5 for unlocking the door (latch 0 (a), which holds Ill in its raised position, and latch 04). This door is made of a strong board such as a steel board or a bulletproof board (tIi). Each support (12) is loosely supported by the edge of the door as shown in Figure 5. In this embodiment, commercially available tin balancers (13a) installed at the upper ends of both sides of the drive device (door openings for lJ and 1-) are used, and wires are (Depending on the country, a spring balancer is connected to an appropriate position on each side of the door (lil). In the figure, (16a)
) It is a u wire stopper. A door (shoes a'7 on both sides of the side edge of the IllO) is provided, and this portion abuts against the corresponding surface of the support Tl21 to ensure that the vertical movement of the door (Ill) is properly controlled.
You will be guided. Latch (preferably, an electric lock with an electromagnetically actuated stopper is used as the 14+. In the illustrated example, a spring balancer is used, so the door 1ll)
latch (14a) holding the underside of the counter (3).
) is used. (Latch C14a at the bottom of +511
) is an operating member such as a switch that unlocks the door. 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 in the example shown in FIG.
One step of descent allows the catch (14') to be retracted and engaged in the hole (lllL).

Preferably, as shown in FIG. 4, a cushioning material (21) is attached to the lower surface of the horizontal member (201) directly above the door 0υ. Also, a counter (3) is attached to the top of the door opening. A flat plate (22) made of a suitable material is installed to match the surface of.

When this security door is opened, the door (111 is held under the surface of the counter (3) by the latch (14a) Ic), as shown in Figures 6 and 4, but when it is closed, the operating member 09 is By operation, the latch (14a) is unlocked, the spring balancer (13a) pulls up the door opening, and the window (2) is closed. 1. Even in an emergency such as when you are robbed, if you touch the operating member (15) Ic,
Similarly, counter 1c (2) is closed. To open the counter (2), the latch (141) may be unlocked and the door Tl1l may be lowered manually.

Alternatively, the door may be lowered automatically.

In addition, in the above embodiment, a pair of spring balancers (
13a) is used, but depending on the relationship between the force of the spring balancer and the weight of the door, it is possible to use even one spring balancer. In addition, the raising of the door is not necessarily limited to the spring balancer, and for example, as shown in Figs.
In this case, both ends of the weight and the bottom of the door (Ill) are attached to the chain wheel (23) [hanging chain (24)
[Therefore, it is connected. Chain wheels on both sides (23) Common shaft of cane (
25) &? : Therefore, if connected, they will be moved up and down while maintaining the horizontal state. A roller (26) may be used instead of the shoe a'7) for guiding the door. Furthermore, this drive device 03) 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. and cannot enter inside.
This makes a significant contribution to crime prevention. Moreover, it has smoke and flame retardant effects, and has disaster prevention benefits.
