Description

  The present invention relates to a security system for preventing a suspicious person from entering the room from the outside, and in particular, suspended items such as blinds and roll curtains (in this specification, suspended by doors, windows, etc.) It shall refer to curtains, blinds, etc. as decorative items).

Conventionally, problems as a security system for preventing a suspicious person from entering the room from outside (referred to herein as a crime prevention system) have been as follows.
(1) The conventional security system has a special key to prevent suspicious persons from entering the room from the outside, and doubles (double lock) the keys such as doors and windows by attaching an auxiliary key. However, new methods that are not related to the type of key have increased, and “key exchange” alone cannot prevent criminal techniques.
(2) Although the method of making the glass of a door and a window into the reinforced glass containing steel wire was taken, it is cut by a glass cutter etc., and a crime cannot be prevented.
(3) Although methods such as attaching a frame made of iron, aluminum, etc. to the casing outside the window with screws are taken, the screws can be easily removed with a screwdriver, so there is little security effect. In addition, the construction cost is increased to attach the frame made of iron, aluminum, etc., and the cost is increased.
(4) A method of installing a security device (including an alarm device) as a security system on a frame part (also referred to as a sash part) of a door or window of a building is taken. The outer peripheral part and the glass part are broken and unlocked, and the suspicious person enters the room, preventing crime.
(5) Further, the security systems (1) to (4) do not have a security system at the time when a suspicious person enters the room.

  In other words, the above (1) to (4) are security systems that prevent a suspicious person from entering through a door or window that is the boundary between the outside and the room, and when the suspicious person enters the room. It is not a security system. The security system cannot prevent theft of important documents in the room, important computer system data, etc. once a suspicious person enters the room. In the following description, the security system that prevents a suspicious person from entering through a door or window that is the boundary between the outside of (1) to (4) and the room is referred to as a first security system. The security system at the time of entering is referred to as a second security system. In addition, there is currently no accurate technology for the second security system.

  The invention described in Japanese Patent Application Laid-Open No. H10-228561 is “invented for the purpose of providing a wiring structure for an obstacle detection device, and has a seat at the lower end of a shutter curtain guided by a guide rail installed in an opening. In a shutter provided with an obstacle detection switch on a plate, a winding wire is connected to the obstacle detection switch, and the lead wire is provided at the lower end portion of the guide rail and is accumulated in the direction of continuous winding. It is characterized by being wound around a tool. "

  In addition, the invention described in Patent Document 2 states that, “With this obstacle detection device, when no obstacle is detected by the detection means, the reflecting member is hidden by the obstacle detection interlocking means, and the obstacle is detected. Since the reflecting member is exposed by the obstacle detection interlocking means when it is done, the reflecting member is in a hidden state in the normal time which occupies most of the time because the opening / closing body has reached the fully open position. For this reason, it is difficult to collect dust on the reflecting member, and it is possible to prevent malfunction of the obstacle detection device ".

  In addition, the invention described in Patent Document 3 states that “the obstacle detection device for an electric shutter according to the present invention is provided with a light receiver on the shutter case side of the electric shutter, and the lower end side of the shutter curtain faces the light receiver. A piezoelectric light emitting means capable of irradiating light, and a pressurizing means for pressurizing the piezoelectric light emitting means by moving a seat plate at a lower end of the shutter curtain relative to the shutter curtain. When the seating plate at the lower end of the shutter curtain comes into contact with the obstacle during the descent of the shutter, the pressurizing unit pressurizes the piezoelectric light emitting unit, and the piezoelectric light emitting unit irradiates light toward the light receiver. It is characterized by being configured to stop the descent of the shutter curtain ".

Japanese Patent Laid-Open No. 06-307174 (second page, left column, lines 40 to 47, and FIGS. 1 to 4) JP 2001-214678 A (page 3, left column 43 to 50, and FIGS. 1 to 8) JP 2002-147151 A (page 2, right column, lines 9 to 20 and FIGS. 1 to 7)

  However, the above-described conventional security system is a first security system for preventing a suspicious person from entering through a door or a window which is a boundary between the outside and the room, and at the time when the suspicious person enters the room. It is not a second security system.

  Further, the invention described in Patent Document 1 includes “1 is a window shutter that is installed on a window, and the window shutter 1 includes a guide rail 2 that is integrally installed on the left and right of the window opening, and the guide rail. 2 is configured using various member devices such as a shutter curtain 3 that is guided to open and close, a winding drum 4 that winds and unwinds the shutter curtain 3, and an opening and closing device 5 that rotates the winding drum 4 forward and backward. The shutter curtain 3 is guided to the guide rails 2 that are integrally built on the left and right of the window opening. Has been. As described above, the obstacle detection device using the shutter curtain 3 is not an alarm device for a suspended suspended article.

  Further, the invention disclosed in Patent Document 2 states that “the building shutter 2 includes a shutter case 3 attached to the upper wall of the opening 1 and a winding that is rotatably built inside the shutter case 3. The upper end of the shaft 4 is connected to the horizontal winding shaft 4, and the shutter curtain 5 that can be unwound from the winding shaft 4 by the rotation of the winding shaft 4, and the left and right sides of the opening 1. Guide rails 6 that are attached to the walls on both sides and guide the opening and closing operation of the shutter curtain 5 by sliding the left and right ends of the shutter curtain 5 as an opening / closing body slidably, and the shutter case 3 An opening / closing machine 8 disposed inside and connected to the winding shaft 4 via a transmission mechanism 7 such as a sprocket or a chain, and a control device 9 for controlling the driving of the opening / closing machine 8 are included. Adult "(Patent Document 2, page 4, 38-50 line right column), has been described as. As described above, the shutter curtain 5 that is an opening / closing body is slidably inserted into the guide rails 6 at the left and right ends of the shutter curtain 5 so that the shutter curtain 5 moves up and down and repeats the opening and closing operation. As described above, the obstacle detection device using the shutter curtain 5 is not an alarm device for a suspended suspended article.

  In addition, the invention described in Patent Document 3 states that “FIGS. 1 and 2 show an example of an electric shutter provided with an obstacle detection device 1. 2 is a shutter case installed at the upper part of an opening of a building, A winding shaft 4 of the shutter curtain 3, an opening / closing device 5 for driving the winding shaft 4, a control panel 6 and the like are internally provided, 7 is a pair of guide rails installed on the left and right sides of the opening, and 8 is a wall surface. The switch box is provided with an open button, a close button, and a stop button for commanding “up”, “down”, and “stop” operations at arbitrary positions of the shutter curtain 3 ”(Patent Document 3). , Page 3, left column, lines 9 to 18). In this way, both sides of the shutter curtain 3 are moved up and down the opened guide rails 7 provided on the left and right sides. As described above, the obstacle detection device using the shutter curtain 3 is not an alarm device for a suspended suspended article.

  Summarizing what has been described above, the conventional security system is a solution to the first security system. The security systems disclosed in Patent Documents 1 to 3 are obstructions below the shutter curtain that moves up and down the side groove. The present invention relates to a detection device that detects an object, and is not a second security system intended to prevent a suspicious person from entering the room from the outside. Also, it is not an alarm device for suspended items.

  Therefore, the present invention has been made in view of the above, and an object of the present invention is a second security system that is a security system at the time when a suspicious person enters a room.

  In other words, the first conventional security system was to increase the strength of doors, window glass, and frame parts (sash parts), and to prevent intrusions from outside by installing a security device. The second security system uses the principle that suspensions such as blinds and curtains installed on the indoor side of doors and windows swing by applying a slight force to the suspensions. The task is to produce an audible alarm in response to the shaking at the time of joining.

  In order to achieve the above-mentioned object, the following measures are taken in the suspension alarm device of the present invention.

  The present invention according to claim 1 is an alarm device for a suspended article which senses a suspended article such as a horizontal blind, a roll curtain, etc. due to external energy, and is detected at the lower part of the suspended article. The suspension device alarm device is characterized in that an alarm unit is provided at a position set from the detected part.

  This is because the alarm device for a suspended article according to the present invention attaches an alarm device that senses the vibration caused by external energy such as wind or force to suspended articles such as horizontal blinds and roll curtains. That is, a second security system that prevents a suspicious person from entering the room at a low cost can be constructed.

  The present invention according to claim 2 is an alarm device for a suspended article that senses a swing caused by external energy in a suspended article such as a horizontal blind or a roll curtain, and an alarm unit is provided below the suspended article. And a detected part is provided at a position set from the alarm part.

  This is the same as in claim 1 above, but the alarm unit, which is a component of the alarm device, is attached to the lower part of the suspended article, and the detected portion, which is another component, is set at the position set from the alarm unit. It is provided. The difference between the first aspect and the second aspect is that the attachments on the other side of the alarm part and the detected part, which are constituent elements of the alarm device, are simply replaced.

  More specifically, in claim 1, the detected part constituted by the magnet base can be easily attached to the lower part of the suspended article (specifically, the lower part of the blind). Can be easily attached to accessories. Further, in claim 2, there is an advantage that the alarm unit can be incorporated in the lower part (specifically, the lower part of the blind) of the suspended article from the beginning of the production of the suspended article.

  The present invention according to claim 3 is an alarm device for a suspended article that senses a swinging suspended article such as a horizontal blind or a roll curtain caused by external energy, and is detected at the lower part of the suspended article. The suspension alarm device is characterized in that a detection portion is provided at a position set from the detected portion, and a detection alarm portion is provided at a position separated from the detection portion.

  This is because the detection unit is provided at a position set from the detected unit, and the detection alarm unit is provided at a position separated from the detection unit. It is separated. For example, by placing a detection unit on an indoor window frame and providing a detection alarm unit at a position away from it (other place in the room, outside the room, etc.), the alarm unit cannot be destroyed when a suspicious person enters. In this way, it is for preventing a problem that no alarm sound is generated.

  The present invention according to claim 4 is an alarm device for a suspended article that senses a suspended article such as a horizontal blind, a roll curtain, etc. suspended by external energy, and is detected at the lower part of the suspended article. The suspension alarm device is characterized in that a detection portion is provided at a position set from the detected portion, and a detection alarm portion integrated with the detection portion is provided.

  This is a combination of the detection unit and the detection alarm unit with respect to the third aspect. The integration means that the wiring of the detection unit and the detection alarm unit is incorporated in the same base, the detection unit and the detection alarm unit are accommodated in the same housing, etc., and by integrating, it is compact and simple. This is to reduce the cost.

  The present invention according to claim 5 is the alarm device for a suspended article according to claim 1 or 2, wherein the alarm device is activated by generation of a magnetic force line by a relative movement of the detected portion constituted by the magnet base and the magnet base. An alarm unit having a switch, and the alarm unit includes an acoustic unit having an electromagnet that generates an alarm sound, and prevents the suspicious person from entering the room by the alarm sound. This is an alarm device for suspended articles such as horizontal blinds and roll curtains.

  This is because a simple member called a magnet base is used for the detected part and a simple structure having a switch and an acoustic part is used for the alarm part, so that an alarm device can be manufactured at a low cost. It is a thing.

  According to a sixth aspect of the present invention, there is provided the alarm device for a suspended article according to the third or fourth aspect, wherein an induced current is generated by generation of a magnetic force line due to a relative movement of the detected portion and the magnet base, and a detected part. And a detection alarm unit having a switch that operates on the magnetic force generated in the coil by the induced current, and the detection alarm unit has an acoustic unit having an electromagnet that generates an alarm sound. The alarm device for suspended articles such as a horizontal blind and a roll curtain for preventing a suspicious person from entering the room by the alarm sound.

  This is because a simple member called a magnet base is used for the detected part, an induction current is generated in the detection part due to the lines of magnetic force, and the detection alarm part has a simple structure including a switch and an acoustic part. By doing so, an alarm device can be manufactured at a low cost.

  The present invention according to claim 7 is the alarm device for a suspended article according to claim 5, wherein the alarm unit includes a self-holding device incorporating a relay circuit. It is an alarm device.

  This is because the alarm device for the suspended goods turns on the alarm unit and emits an alarm sound due to the swing of the suspended article, but when the vibration returns to the initial position, the alarm is turned off and the alarm sound stops. In order to avoid this, once the alarm unit generates an alarm sound, a relay circuit is connected to the alarm unit's electric circuit so that the alarm sound continues to sound unless the alarm unit's electric circuit is manually shut off. It has a built-in self-holding device. By doing so, when an alarm sound is generated once due to the intrusion of a suspicious person, the alarm sound of the alarm device is not stopped unless the electric circuit of the alarm unit is manually turned off.

  The present invention according to claim 8 is the alarm device for a suspended article according to claim 6, wherein the detection alarm unit has a self-holding device incorporating a relay circuit. Alarm device.

  This has a self-holding device in which a relay circuit is incorporated in the electric circuit of the detection alarm unit, similarly to the alarm unit of claim 7. Since the function of the detection alarm unit is the same as that of the alarm unit, a description thereof will be omitted, but the detection alarm unit manually turns on the electric circuit of the detection alarm unit when an alarm sound is emitted once due to the intrusion of a suspicious person. Unless it is turned off, the alarm sound of the alarm device does not stop.

  The present invention has the following effects from the above description.

  The present invention is designed for use in everyday life, such as blinds, which do not require large-scale construction, and can be easily used for crime prevention products at low cost. Does not lose its original function as a decorative product, but also fulfills the basic functions of sun protection and decoration.

  In addition, the present invention allows the security system to be installed later on the already installed blinds, which does not require complicated construction and can be installed at low cost. became.

  In addition, when a suspicious person enters the room from the outside, it naturally touches the suspended items such as curtains and blinds, so the suspended items are shaken and displaced from the stationary position, and the alarm device is activated. A warning tone sounds at a high tone. However, it is clear that it is impossible for a suspicious person to attempt to enter a room without touching his / her equipment. Therefore, the present invention fulfills the function of the second security system.

  In addition, in the present invention, it is only necessary to set the alarm device to the switch OFF state in everyday life, and to set the alarm device to the switch ON when going out, and the alarm device is activated (ON state) with a simple operation. Can do.

  In addition, the present invention can construct a security system simply by placing a set bar incorporating an alarm unit of an alarm device on the indoor window frame when going out when the object to be detected is provided at the lower part of the suspended item. There is no problem in daily life and the beauty is not impaired.

  In addition, the present invention is designed to prevent danger when a small child approaches a window and touches a suspended item, because it functions as a security system and generates an alarm sound. It can also be used as a security system that can respond to small winds caused by forgetting to close windows, so you can prevent forgetting to close windows, even if an indoor fire occurs. The suspension system is shaken by the flow of wind due to the fire, and the security system is activated and an alarm sound is generated. Therefore, it can also be used for indoor fire prevention.

In (b), the detected part 1 is composed of a magnet base 11 and a cradle 12, the magnet base 11 is embedded in the cradle 12, and the detected part 1 is attached to the blind lower part 53 with screws 13 and 13. (C) is the one in which the magnet base 11 as the detected portion 1 is inserted and fixed in the cylindrical blind lower part 63. Since the magnet base 11 is visible from the hole 631 drilled in the blind lower part 63, the magnet base 11 can be set and fixed at a predetermined position. Moreover, although (a) and (b) described the embodiment of the horizontal blind 50, it can be similarly applied to the roll curtain 60, and (c) describes the embodiment of the roll curtain 60. However, the horizontal blind 50 can be similarly implemented. As described above, the detected portion 1 may be configured by the magnet base 11 alone, may be configured by the magnet base 11 and the cradle 12, and may have various other configurations. In addition, there are various methods such as embedding, screwing, insertion, adhesion, and fixing for the installation or attachment of the detected portion 1 to the blind lower portion 53 or 63, and these may be set as appropriate.

  Next, FIG. 10 is an electrical circuit diagram of an alarm unit for explaining the first and second embodiments (FIGS. 1 and 2) of the alarm device of the present invention. (A) is in the OFF state when the switch is attracted to the magnet base, and (b) is in the OFF state when the switch leaves the magnet base and the iron piece contacts the end of the electromagnet and the electric circuit is in the OFF state. (C) is a switch ON state, and an iron piece contacts a contact piece and an electric circuit is in an ON state.

  Next, a first embodiment of the alarm device according to the present invention will be described with reference to FIGS. 1, 5, 6 and 10. FIG. As shown in FIG. 1, the alarm device of the present invention includes a detected unit 1 configured by a magnet base 11 and an alarm unit 3 configured by an electric circuit that emits an alarm sound. Then, as shown in FIG. 6, the horizontal blind 50 is tilted to the left side by external energy from the right side. As a result, the detected portion 1 constituted by the magnet base 11 installed in the lower blind portion 51 of the horizontal blind 50 is free from the influence of the magnetic lines of the magnet base 11 on the switch 31 due to the leftward movement of the horizontal blind 50 ( Precisely, the influence of the magnetic field lines is weaker than the force of returning to the ON side of the switch 31.) Therefore, the alarm installed or placed in the indoor window frame 81 or embedded in the set bar 70 provided The switch 31 of the electric circuit of the unit 3 changes from the OFF state to the ON state.

  That is, in (a), the switch 31 is in the OFF state due to the magnetic force of the magnet base 11, but the detected blind 1 is moved from the right side by an external force as shown in FIG. 6 (b). When it is swung to the left, the distance between the magnet base 11 installed in the lower blind portion 53 and the alarm unit 3 changes. Therefore, the magnetic force that has caused the switch 31 to be in the OFF state is weakened by the magnetic force of the magnet base 11, and the switch 31 is turned off. Turns on. Of course, the switch 31 is set to be in the switch ON state when the magnetic force of the magnet base 11 of the detected portion 1 does not work. Therefore, unless a magnetic force acts on the switch 31, the switch 31 is turned on. In consideration of the case where the alarm device is not used, the manual switch 37 is provided in the electric circuit. When the alarm device is used, it is a condition that the manual switch 37 is in an ON state. . When the alarm device is not used, the manual switch 37 is turned off.

  Next, the acoustic unit A of the alarm unit 3 will be described. The acoustic part A winds the electromagnet coil 33 around the iron core 34, and when a current flows through the electromagnet coil 33, magnetic force is generated, and the iron piece 35 is attracted to and brought into contact with the end 341 of the iron core 34. If it does so, since an electric circuit will cut | disconnect and an electric current will be cut | disconnected, magnetic force will lose | eliminate, the iron piece 35 will return to an original position with a spring force, and the contact piece 36 and the iron piece 35 will contact. Then, a current flows through the electric circuit, and the state (b) is obtained. By repeating steps (b) to (c) and (c) to (b), the hitting sound or vibration sound between the iron piece 35 and the end 341 and the hitting sound or vibration sound between the iron piece 35 and the contact piece 36 are obtained. Repeats and sounds an alarm sound.

  In other words, the alarm sound is generated when the switch 31 of the electric circuit of the alarm unit 3 is ON. In FIG. 10A, the switch 31 is attracted to the magnet base 11 and the switch is in the OFF state and the electric circuit is in the OFF state. In FIG. 10B, when the switch 31 is turned on, a current is supplied to the electromagnet coil 33. It flows into the electromagnet 32 and the iron piece 35 is attracted to and contacts the end portion 341 of the iron core 35 to cut off the electric circuit current. Then, in (c), the magnetic force of the electromagnet 32 is lost, and the iron piece 35 returns to its original position by the spring force of the iron piece 35, contacts the contact piece 36, and a current flows through the electric circuit. Then, since an electric current flows through the electromagnet coil 33 of the electromagnet 32, a magnetic force is generated in the electromagnet 32, and the iron piece 35 is attracted and brought into contact with the head portion 341 of the iron core 34 to be in the state (b). The operations of (b) and (c) are repeated at high speed and vibrated to generate a sound, which becomes an alarm sound.

  In addition, this electric circuit is a mechanism for generating an alarm sound. However, if it is a radio wave transmission electric circuit (including an electronic circuit) that transmits a radio wave signal, it can transmit radio waves. In other words, the sound unit A of the alarm unit 3 can be used as a transmission circuit, and a reception circuit can be set at another place so that an alarm or the like for notifying abnormality can be recognized.

  Further, the second embodiment of the alarm device of FIG. Further, when an alarm device is attached to the roll curtain 70 of FIG.

  Next, FIG. 11 is a drawing of an electric circuit for explaining a detection alarm unit of the alarm device of the present invention. The alarm device to which the detection alarm unit of FIG. 11 is attached includes a detected unit, a detection unit, and a detection alarm unit. Accordingly, description will be made with reference to FIGS. 1, 5, and 11. FIG.

  The alarm device of the present invention will be described with reference to FIG. The detected portion 1 is provided in the lower blind portion 53 of FIG. 1, the detecting portion 2 is installed or embedded in the set bar base 11 in place of the alarm portion 3 of FIG. 1, and the detecting alarm portion 4 is provided at a position away from the horizontal blind 50. Provided. Naturally, the detection alarm unit 4 is separated from the detection unit 2. By the way, “separated” in this case means being away from the horizontal blind 50 by being away from the side of the window to which the horizontal blind 50 is attached, outside, or the like. . The detection unit 2 may be installed or placed on the indoor window frame 81 instead of being embedded in the set bar base 71.

  In the above description, the detection unit 2 and the detection alarm unit 4 are provided at positions separated from each other, but the detection unit 2 and the detection alarm unit 4 may be integrated. `` Integration '' in this case refers to incorporating the wiring of the detection unit and detection alarm unit on the same base, housing the detection unit and detection alarm unit in the same housing, etc., by integrating, Compact, simple and low cost can be achieved.

  And the electric circuit in the alarm device of the present invention comprises an alarm unit 3 that catches the reaction of the detected unit 1 of the magnet base 11 with respect to the electric circuit, and a detection alarm that generates a sound and a signal with the detection unit 2. Part 4 is separated. When the magnet base 11 of the detected part 1 moves, a current flows in a coil (not shown) provided in the detecting part 2 by electromagnetic induction, and a current flows in the coil 49 of the detection alarm part 4 by the current flowing by this electromagnetic induction. Then, the magnetic field changes and the switch 41 is turned ON / OFF (the connection of the coil 49 is not shown). FIG. 11 corresponds to the state of FIG. 10A, and the electric circuit of the alarm device of FIG. 11 also emits an alarm sound by repeating the states of FIGS. 10B and 10C. Details have been described with reference to FIG.

  Also, when the detection alarm unit 4 of FIG. 11 is attached to the roll curtain 60 of FIG.

  Next, FIG. 12 is a drawing of an electric circuit when a relay circuit as a self-holding device is incorporated in the alarm unit of the alarm device of the present invention. As illustrated, the alarm unit 3 includes a self-holding device in which a relay (also referred to as a relay) 39 is incorporated between the switch 31 and the manual switch 37. Since the acoustic part A including the electromagnet 32 is the same as that of FIG. 10, it is omitted (not shown). By the way, in the electric circuit of the alarm unit 3 in FIG. 10, the magnetic lines of force of the magnet base 11 change due to the swing of the suspended article and the switch 31 of the alarm unit 3 is turned on to generate an alarm sound. When returning, the switch 31 is turned OFF and the alarm sound stops. On the other hand, in FIG. 12, by incorporating a self-holding device incorporating a relay circuit into the electric circuit of the alarm unit 3, an alarm sound is continuously generated.

  That is, in FIG. 12, in order to prevent the alarm sound from stopping when the swing of the suspended article returns to the initial position as shown in FIG. If a self-holding device incorporating a relay circuit as a bypass circuit in the switch 31 portion of the electric circuit of the alarm unit 3 is provided so that the alarm sound continues to sound unless the electric circuit of the alarm unit 3 is manually interrupted. It is what you have. In this way, when an alarm sound is generated once due to the intrusion of a suspicious person, the alarm sound of the alarm device is not stopped unless the electric circuit of the alarm unit 3 is manually turned off. In FIG. 12, when the switch 31 is turned on, a current flows through the circuit of the relay 39 including the coil 391 and the switch 392, and the switch 392 is turned on by the magnetic force due to electromagnetic induction of the coil 391. Is continuously energized, the switch 392 continues to be in the ON state. In other words, the circuit of the relay 39 works and the electric circuit of the alarm unit 3 is a device that has a self-holding function so as to hold the connection state. Therefore, the alarm sound generated once is stopped by shutting off the electric circuit by the manual switch 37 (the manual switch 37 is in the OFF state).

  12 illustrates the case where the alarm unit 3 of FIG. 10 is provided with a self-holding device using a relay circuit, but the detection alarm unit 4 of FIG. 11 may be similarly provided with a self-holding device using a relay circuit. it can. The function in this case is the same as in FIG.
