JP3074927U - A conventional device that leaves traces of opening and closing doors - Google Patents

Abstract

(57) [Summary] [Problem] A device in which when a door or the like is opened by another person, the trace remains, and even if the trace is erased, the trace remains. A luminous body emits light when a reed switch is separated from a magnet. It can be turned off only by the lock, and it is counted each time the lock is used, and the number of times used is continuously displayed without disappearing. In order to open the apparatus, the cork sheet must be peeled off, and the shape is stored in a photograph or the like.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for leaving a trace of a person who intrudes into a house or a room by using a device intentionally made, but technically, a logic circuit 25 is used. It belongs to the technology of controlling the voltage in combination and mechanically releasing it to achieve the purpose.

[0002]

[Prior art]

 There are devices that activate the sensor when a person comes near the door 20 and automatically leave a mark on the video camera, and devices that activate the sensor and turn on the lighting. The mechanism for counting and displaying the number of times the lock 4 is used is the same as that of a pedometer.

[0003]

[Problems to be solved by the invention]

 The device 18 is small and has a structure 7, 8, 9 in which the inside of the device 18 cannot be opened unless destroyed. When the door 20 is opened by another person, the trace remains, and even if the trace is to be erased, it is erased. It is necessary to have the structure 7, 8, 9 that is devised so as to allow the internal battery to be replaced or repaired in the device 18 in which such traces remain.

[0004]

[Means for Solving the Problems]

 In order to visually recognize that the door 20 and the like have been opened, the luminous body 3 emits light when the door 20 is opened, and once it emits light, it cannot be turned off unless the internal switch 2 is pressed by the push lock 4 ( By devising FIGS. 1 and 2) and attaching a device (FIG. 3) capable of displaying the number of times the lock 4 is turned off even if the lock 4 is turned off by any method, the door 20 or the like is provided. So that you can know that someone was trying to open it.

Further, in order to obtain structures 7, 8, and 9 that cannot be opened unless they are broken, screws 6 are fixed on both sides of the case 16 and a cork sheet 7 is bonded 8 from above, and It is possible to confirm by removing the case cover, but it is conceivable that another person removes the case cover 9, opens the inside of the device 18, and then reattaches the cork sheet 7. Therefore, the screws 6 on both sides of the case 16 are considered. When the cork sheet 7 is attached to the cork sheet 7 from above, the appearance of the cork sheet 7 is stored in a photograph or the like, so that if the appearance of the cork sheet 7 has changed, another person has opened the device 18. You can see that. In this case, it is better not to put the adhesive 8 between the cork sheet 7 and the case cover 9 as shown in FIG. If so, it is better to use one or the other. The case carver 9 is prevented from falling off by the ring 29.

[0006] Each time the battery is replaced, the cork sheet 7 is reattached neatly.

The circuit is protected by the fuse 27.

[0008]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. FIG. 1 shows an electronic circuit in which a light emitter 3 emits light when the power supply 1 is cut off. Although not shown in FIG. 1, 0.1. A fuse of A to 0.5 A is inserted.

FIG. 2 shows a structure in which the light emitting body 3 is turned off by mechanical means using an extruded tablet 4.

FIG. 3 is a view showing the mounting on the board 13 for capturing the number of times the lock 4 is turned. The wiring 22 is arranged so that when the protruding portion 14 on the substrate 13 comes into contact with the metal plate from which the extruded tablet 4 is pushed out, it is energized and counted. The extruded tablet 4 is made of a conductive metal, and is wired to it. Two count wires 22 extend from the counter display 12 and are connected to the protrusion 14 and the push lock 4.

FIG. 4 shows FIGS. 1, 2 and 3. The appearance which combined. Implementation omission view seen from above. The size of the substrate 13 is 72 mm × 78 mm, and the thickness is 1 mm to 2 mm.

FIG. 5 is a cross-sectional view of the device 18 cut from the center of the set screw 6 on both sides. The shape of the case 16 is a hollow cube of 80 mm × 115 mm × 22 mm and the thickness is about 1 mm. The shape of the cork sheet 7 is a rectangle of 80 mm × 20 mm and a thickness of 2 mm to 5 mm, which is firmly adhered to both sides of the case 16, and when it is peeled off, it becomes ragged. Can be checked.

A hole is formed in the carver 9 so that the count 5 and the light-emitting body 3 can be confirmed. Since the purpose is to cover and hide the case 16 and change the appearance except that the hole of the lock 4 is opened, the shape can be freely set. Nothing needs to be inserted between the device 18 and the case carver 9. Stop with a sticker that can be seen to be peeled off.

FIG. 6 shows an embodiment of the invention. In the case of attaching to the door 20 with the velcro tape 10 or the like (a-1), the reed switch 1 and the magnet 21 are attached so that the sensitivity is good on the opposite side to the attached side, that is, after attaching to the front side of the door 20. . That is, the magnet 21 is attached to the wall 19 so as to come above the reed switch 1 with the door 20 closed. When the device 18 is mounted on the wall 19 (b-1), the reed switch 1 is mounted on the side opposite to the side on which the device 18 is mounted, that is, when mounted on the outside of the wall 19. The magnet 21 is attached to the inside of the door 20 so as to have high sensitivity. The same applies to (a-2) and (b-2) when embedded in the door 20 or the wall 19.

The reed switch 1 is mounted with a thick door 20, a wall 19, etc. therebetween so as not to be affected by other magnetism. If this is not possible, attach the lead switch 1 to the tip of the projection, etc., and attach the magnet 21 so that the sensitivity is good.

When the number of reed switches 1 is increased, a lot of open / close can be monitored.

[0017]

[Effect of the invention]

 The door 20 was opened and closed. Alternatively, it is possible to know that it is about to be opened and closed, and the trace cannot be erased unless the battery is exhausted or the device 18 is destroyed. Since the size of the device 18 is fixed, the device 18 can be embedded in the door 20 or the wall 19 for use. The appearance can be varied because the case 16 is covered with the carver 9.

FIG. 3 is a view of mounting on the board 13 for capturing the number of times the lock 4 is turned. When the protrusion 14 on the substrate 13 comes into contact with the metal plate from which the extruded tablet 4 is pushed, the wiring 22 is energized and counted. The extruded tablet 4 is made of a conductive metal, and is wired to this. Two counter wires 22 extend from the counter display 12 and are connected to the protruding portion 14 and the push-out lock 4. Counting unit 12 is reset when multiplied by externally al high voltage to the tablet 4.
