Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a card insertion hole that inserts and removes cards from the outer seat side to the inner seat side. , relates to a card lock having a card reader.

0002

[Conventional technology]

Traditionally, card readers for this type of card lock are made of synthetic resin or zinc die. The reality is that they are manufactured from low melting temperature alloys such as cast.

0003

[Problem that the idea aims to solve]

However, since the material of the above card reader is synthetic resin or low melting temperature alloy, In the case of a synthetic resin card reader, if a fire breaks out indoors, the same card The reader ignites due to the heat, and the flames and hot air (wind) are diffused and discharged from the card insertion hole to the outside. This caused the fire to spread. In the case of the latter low-melting temperature alloy card reader The same card reader melted down, and the flames and hot air were diffused and discharged to the outside as before. There was a drawback. In addition, when a fire occurs outside the room, contrary to the above, the flames and hot air will spread to the inside. This caused the fire to spread. This device is designed to prevent fires from occurring indoors (or outdoors) in the event of a fire occurring indoors (or outdoors). Make sure that the flames and hot air do not penetrate the door and spread to the outside (or inside) of the room. It is intended to prevent the spread of fire and eliminate all of the above drawbacks. It has been resolved.

As shown, the card insertion hole 13 of the outer case 1 and card reader 12 is open during normal operation. A shutter 30 is provided. As shown in FIG. 6, this shutter 30 has a horizontally bent portion on a flat vertical plate. 31 is formed, and the spring receiver 33 is held in the through hole 32 of this bent portion 31. 3 is always biased downward by a spring 34 provided at the The lower end 30A of the shutter 30 resists the biasing force and the contact portion 1 of the card reader 12 It is designed to be locked to 2A. Therefore, as mentioned above, the indoor side is at high risk of fire, etc. When the temperature is generated, the high temperature reaction member 20 is fused and the card reader 12 is opened as shown in FIG. The lower end 30A of the shutter 30 touches the contact part 12A of the card reader 12. Therefore, when the shutter 30 is no longer locked, the shutter 30 is moved downward by the biasing force of the spring 34. The shutter 30 is inserted into the card insertion holes 13, 13 on the outer case or the card slot on the outer case. Block the heater insertion hole (not shown) and exhaust the flames and hot air from the indoor side to the outdoor side. prevent.

0012 The vertical plate portion 30B of the shutter 30 is attached to the shutter holder 35 that is placed against the door A. While in contact with the outer end surface 35A, insert the insertion hole 35 of the shutter holder 35 from the indoor side. B. In the guide groove 30C of the shutter 30 and the insertion hole 10B of the outer inner case 10. At the same time, insert the male thread 3 of the screw 37 into the female thread 36A of the threaded post 36. Screw 7A and secure. In addition, the elongated hole 30A of the shutter 30 is Insert the screw 38 between the screw hole 35C of the case 35 and the screw hole 10C of the outer inner case 10. Through this process, these three parties are fixed.

[0014] Note that the mounting structure of the card reader 12 is not limited to that of the above embodiment. For example, as shown in FIG. 13, the card reader 12 is inserted into the card reader insertion hole 1A of the outer case 1. The small diameter portion 12B at the front end is inserted and the front end surface 12C of the small diameter portion 12B and the front end surface of the outer seat 1 are connected. are on the same plane, and the card insertion hole is the card insertion hole 1 of the card reader 12. It may be only 3, and the design can be changed arbitrarily. In this case, a fire inside the room, etc. When the card reader 12 melts, the action of the high temperature reaction member 20 (not shown) The card reader 12 is moved backward, and the shutter 30 is moved down to open the outer seat 1. The card reader insertion hole 1A is closed to prevent hot air from being discharged to the outside.

[0015] The shutter 30 is moved so as to close the card insertion hole in the event of a high temperature event such as a fire. As a method of melting the high temperature reaction member 20 as in the above embodiment, the card reader can be The method shown in FIGS. 14 to 17 is not limited to the method of moving the door 12 and lowering the shutter 30. or any other configuration can be adopted.

[0016] In the case of FIG. 14, the small diameter portion 12B formed at the front end of the card reader 12 is heated to a desired temperature. The high-temperature reaction member 20 is made of a material that melts at Due to the generation of heat, this high temperature reaction member 20 melts and falls, and the shutter 30 moves down to release the outer seat. The card insertion holes 13, 13 are closed. In this case, the The reader 12 can be implemented even if it does not melt at all. Card reader 12 is in front Card reader mounting plate 14 shown in the embodiment (however, spring 16, cylindrical part 21, etc. are not required) It may be attached to a frame or other frame. Same as above example Reference numerals indicate similar configurations.

[0017] The one in FIG. 2C, a gap 40 for the shutter 30 to be inserted is formed in advance, and this gap is A shutter 30 is suspended by a spring 34 above the shutter 40 so as to be movable up and down. The bent portion 31 of the shutter 30 is normally connected to a high temperature reactor such as a thermal fuse or shape memory alloy. It is suspended from the upper horizontal plate 10D of the outer inner case 10 by a response member 20, and is When the temperature reaches a constant temperature, the high temperature reaction member 20 melts or changes shape, causing the spring 34 to be attached. Use force to move the shutter 30 down and close the card insertion holes 13 and 13 on the outer seat. This is what is written.

[0018] Note that, without providing the spring 34 in the case of FIG. A high temperature reaction member 20 made of a shaped member is provided, and the lower position of the shutter 30 is In this case, a member for locking the lower end 30A of the shutter 30 is horizontally installed inside the outer seat 1. It is possible to adopt a structure in which:
