Description

  The present invention relates to an improvement of a shutter device.

  Conventionally, as this type of shutter device, for example, mainly for crime prevention purposes, the shutter device is installed at the entrance of a building or structure (hereinafter referred to as “building or the like”) and includes a plurality of slats connected in the vertical direction. The shutter panel, a drum that winds up the shutter panel, and guide grooves that are provided on pillars or the like and guide the left and right ends of the shutter panel are configured.

The shutter device configured in this way basically blocks not only the entrances and exits of buildings, but also all the spaces between the pillars, and is constructed at night and on holidays when it becomes less popular from buildings. The main purpose is to make it difficult for a burglar to infiltrate an object or the like (see Patent Document 1).
JP-A-7-127362 (FIGS. 9 and 10)

  That is, in the conventional shutter device, the entrance of a building or the like can be blocked, but the space between the columns is blocked. Therefore, the shutter panel is long in the left-right direction and takes time to open and close.

  Then, when operating a store or the like in a building or the like, with a conventional shutter device, even if a burglar invades a store or the like that is in operation, it is difficult to catch the robber. As a result, it can be said that there is a crime deterrent effect against crime prevention at night and the like, but it is difficult to be useful for crime prevention at a store in operation.

  Therefore, the present invention has been developed to improve the above-described problems, and an object of the present invention is to provide a shutter device that has an excellent crime deterrent effect on a store or the like that is in business.

  In order to achieve the above object, a shutter device according to the present invention includes a shutter panel formed by connecting a plurality of slats in a lateral direction, an arc-shaped hanger rail that slidably suspends each slat, and a lower end of each slat. Are configured to include an arc guide rail that slidably guides the slat, and a drive unit that drives the slat at the forefront of the shutter panel along the hanger rail.

  In addition, another shutter device of the present invention includes a pair of shutter panels formed by connecting a plurality of slats in the lateral direction, an arc-shaped hanger rail for slidably suspending each slat, and a lower end of each slat freely slidable. And a drive means for driving a slat at the forefront of each shutter panel along the hanger rail, and is set to be double-opened.

  In the shutter device of the present invention, since the most advanced slat of the shutter panel is driven, it is possible to close the shutter device at high speed by sliding the shutter panel at high speed along the hanger rail and the guide rail.

  Further, since the hanger rail and the guide rail are arcuate, the shutter panel is driven at a position where the door is avoided regardless of the door type of the doorway, so that the shutter device can be reliably closed.

  Therefore, when operating a store or the like in a building or the like, it has been difficult for a conventional shutter device to catch a robber even if a burglar invades during the operation, but the shutter device of the present invention reliably closes at high speed. Therefore, it is possible to prevent a person who seems to be a burglar from entering the store, and further to capture the robber in the store.

  And because the robber can be informed of the existence of a shutter device that closes at high speed, he realizes that he will be caught or attempted even if he commits a crime for robbery not only at night but also during daytime business. The crime deterrent effect can be improved dramatically.

  In addition, since the shutter panel slides along the arc-shaped hanger rail and the guide rail, even if the doorway of the store or the like is arranged at the center between the pillars of the building or the like, It can be installed without difficulty, can be installed without difficulty at the entrance / exit arranged in the corner, and the shutter device can be installed in a store or the like in a space-saving manner.

  Further, since the shutter panel slides along the arc-shaped hanger rail and the guide rail, even if the door of the entrance / exit is an inward opening door, it becomes impossible for a person to enter / exit from the entrance / exit by retrofitting the shutter device. Therefore, the versatility and practicality of the shutter device are improved.

  Further, when the shutter device is double-opened, the moving distance of each shutter panel is shortened, so that the shutter device can be closed at a higher speed.

The tension spring 79 is urged, and the tensioner sprocket 78 is engaged with the middle portion of the string far from the hanger rail 4 to give tension to the chain 73.

  Therefore, the tension of the chain 73 is optimally maintained by the tensioner 76, and the chain 73 is prevented from falling off the sprockets 71 and 72.

  The motor 75 is attached to the frame F, and the power of the motor 75 is transmitted to the sprockets 71 and 71 via the belt transmission mechanism 80, the bevel gear mechanism 81, and the chain transmission mechanism 82, which are also attached to the frame F, respectively. By driving the motor 75, the left and right chains 73, 73 are driven in directions opposite to each other.

  That is, when the motor 75 is rotationally driven to one side, the left chain 73 is guided clockwise by the guide member 74 and the right chain 73 is guided counterclockwise by the guide member 74 in FIG. The slats 2, 2 connected to the links a, a of the chains 73, 73 move away from each other, and the shutter panels 3, 3 are driven in a direction to open in synchronization with each other. The shutter device S can be opened by being housed in the shutter boxes 6 and 6.

The slats 2, 2 connected to the links a, a of the chains 73, 73 move in a direction approaching each other, and finally the slats 2, 2 contact each other via the cushion members 26, 26. The shutter panels 3 and 3 are driven in a closing direction synchronously, and the shutter device S is closed.

  The chains 73 and 73 are guided along the hanger rails 4 and 4 by the guide members 74 and 74 when driven, so that the shutter panels 3 and 3 can slide along the hanger rails 4 and 4. Since the slats 2 and 2 at the forefront in the closing direction of the shutter panels 3 and 3 are driven, the shutter panels 3 and 3 can be driven in the closing direction at high speed. The smooth movement of the spherical body 9 with respect to the hanger rail 4 and the guide rail 5 makes the slide of the shutter panels 3 and 3 smooth, and the shutter panel 3 and 3 can be moved further in the closing direction. .

  Further, each slat 2 is provided with a roller 25 that rolls in contact with the upper surface of the hanger rail 4 and slide members 24, 24 that face the side surfaces of the hanger rail 4 via brackets 23. In this respect, smooth movement of the shutter panel 3 is ensured and high-speed movement of the shutter panel 3 in the closing direction is ensured.

  Further, the shutter box 6 is not a drum winding type like a conventional shutter device, and the spiral empty portion 63 does not hinder the movement of the shutter panel 3 in the closing direction. Fast movement in the direction is guaranteed.

  The motor 75 described above is controlled by a controller C installed in the store R, and basically, the shutter device S can be opened and closed by manually operating the controller C.

  Since the motor 75 is used as the driving source for the shutter panels 3 and 3, the opening / closing speed of the shutter panels 3 and 3 can be easily controlled, and the responsiveness is good. If the torque of the motor 75 can be detected during the opening / closing driving of the shutter panels 3 and 3, and the driving of the motor 75 is stopped when the torque exceeds a predetermined value, the shutter panel 3 can be stopped. , 3 can be automatically stopped when fully opened and closed, and the motor 75 is automatically stopped when a person or the like is caught between the shutter panels 3 and 3. can do.

  Further, when the shutter panels 3 and 3 are closed, the state-of-the-art slats 2 and 2 are provided with cushion members 26 and 26, respectively. Even if the shutter panels 3 and 3 collide with each other when moving to the closing position, the cushion members 26 and 26 reduce the impact at the time of the collision.

  Next, locking of the shutter panels 3 and 3 after the shutter panels 3 and 3 have moved to a position where the shutter device S is completely closed will be described.

  As shown in FIGS. 7 and 8, the structure for locking the shutter panels 3 and 3 includes a receiver 92 having a hole 91 provided in the slat 2 at the forefront of each shutter panel 3 and 3, and A rod 93 that can be inserted into and removed from the hole 91, a solenoid 94 that is a rod driving means for moving the rod 93 forward and backward toward the hole 91, and an external part that is held by the slat 2 and is provided outside the slat 2 by the advancement of the rod 93. A movable rod 96 inserted into the hole 95 and a spring 97 as a biasing means for biasing the movable rod 96 in the direction of retreating from the external hole 95 are provided.

  The metal receiver 92 is attached to the front side of the square pipe 22 of the slat 2 in FIG. 7, and a hole 91 penetrating vertically is provided in the metal receiver 92. A rod 93 driven along the vertical direction can be inserted.

  The rods 93, 93 that are inserted into and removed from the respective holes 91 of the receiving plates 92, 92 are both attached to the plate 94 b that is connected to the movable iron core 94 a of the solenoid 94 fixed to the frame F. When the solenoid 94 is driven, the rods 93 and 93 are moved up and down synchronously. When the slats 2 and 2 are moved downward when the shutter device S is completely closed, the rods 93 and 93 are inserted into the holes 91. The upper end portions of the slats 2 and 2 are fixed so as not to move from the spot, the shutter panels 3 and 3 are locked, and the shutter device S can be kept closed. On the contrary, when the rods 93 and 93 are moved upward, the rods 93 and 93 come out of the hole 91 so that the slats 2 and 2 can be moved.

  The movable rod 96 is divided into an upper movable rod 96a and a lower movable rod 96c. The upper movable rod 96a is attached to the front of the square pipe 22 of the slat 2 in FIG. The two rod guides 98a and 98b are supported so as to be movable up and down, the movable rod 96a is inserted, and the spring receiver 96b provided in the middle of the movable rod 96a and the rod guide 98b of the slat 2 below. It is urged | biased upwards with the spring 97 interposed between the spring receivers 100 attached to the position.

  The lower movable rod 96c on the other side is also supported by two rod guides 99a and 99b attached to the front of the square pipe 22 of the slat 2 in FIG. 7 so as to be vertically movable, and the movable rod 96c is inserted. At the same time, it is directed upward by a spring 97 interposed between a spring receiver 96d provided in the middle of the movable rod 96c and a spring receiver 101 attached at a position below the rod guide 99b of the slat 2. Is encouraging.

  In addition, in front of the square pipe 22 of the left slat 2 in FIG. 7 and immediately below the spring receiver 100, a hole 110 into which the tip of a movable rod 96a provided on the left slat 2 is inserted and removed, and a right side An arm 112 having a hole 111 through which a tip of a movable rod 96a provided in the slat 2 is inserted and removed is attached, and the rods 93 and 93 are moved downward to push the movable rods 96a and 96a downward. The movable rods 96a and 96a are inserted into the holes 110 and 111, respectively, and the slats 2 are integrated with each other at the intermediate portion to lock the shutter panels 3 and 3 so that the shutter device S is closed. Can be maintained. Conversely, when the rods 93 and 93 are moved upward, the movable rods 96a and 96a are moved upward by the springs 97 and 97, extracted from the holes 110 and 111, and the slats 2 and 2 can be moved. It can be.

  Furthermore, the external hole 95 is specifically provided in the outer peripheral side rail 52 of each guide rail 5 and 5. When each of the slats 2 and 2 is in a position to completely close the shutter device S, when the lower movable rods 96c and 96c are moved downward, the distal ends of the movable rods 96c and 96c are respectively connected to the outer holes 95 and 96, respectively. 95, the lower ends of the slats 2 and 2 are fixed immovably from the spot, the shutter panels 3 and 3 are locked, and the shutter device S can be kept closed. On the contrary, when the movable rods 96c, 96c are moved upward, the movable rods 96c, 96c come out of the external holes 95, 95 by the urging force of the springs 97, 97 to move the slats 2, 2. can do.

  The lower movable rods 96c and 96c are pushed down via the upper drive rods 96a and 96a when the rods 93 and 93 driven by the solenoid 94 move downward. By driving, it is possible to switch between fixing and opening the lower end portions of the slats 2 and 2.

  Therefore, by driving the solenoid 94 and moving the rods 93 and 93 up and down, the shutter panels 3 and 3 can be switched between fixing and opening, so-called French dropping structure. Since the upper and lower portions and the middle portion can be fixed, the shutter device S can be firmly locked in the closed state.

  The left movable rod 96 may be integrated with the upper movable rod 96a and the lower movable rod 96c without being divided.

  Since the solenoid 94 is used, the shutter panels 3 and 3 can be locked instantaneously. The solenoid 94 may be driven manually by the controller C as in the case of the motor 75. For example, a position sensor that detects the position of each slat 2, 2 is provided to provide the shutter device S. A control device for driving the solenoid 94 may be provided so that it can be determined whether or not the shutter panel is closed, and the shutter panels 3 and 3 may be automatically locked when the shutter device S is closed. . In this case, it is desirable to control the motor 75 to stop driving when the shutter device S is closed when the shutter device S is closed.

  As described above, the shutter device S is double-opened, but the left or right side portion of the shutter device S in FIG. 1 can be independently formed as a single-open shutter device, as shown in FIG. If the one-side shutter device S2 is installed at the entrance E2 of the corner of the store etc. R, the shutter device S2 does not waste the space of the store etc. R. In the case of a single opening, the arm 112 provided on the slat 2 may be provided on the wall of the store or the like R, and even if the arm 112 is not provided, it can be fixed above and below the slat 2. Since this is possible, there is no problem in terms of locking the shutter panel 3.

  In the shutter devices S and S2 configured as described above, the most advanced slat 2 of the shutter panel 3 is driven as described above, so that the shutter panel 3 is moved along the hanger rail 4 and the guide rail 5. The shutter device S can be closed at high speed by sliding at high speed.

  Further, since the hanger rail 4 and the guide rail 5 are formed in an arc shape, the shutter panel 3 is driven at a position that avoids the door regardless of the door type of the entrances E and E2, so that the shutter devices S and S2 are surely installed. Can be closed.

  Accordingly, when operating a store R in a building or the like, it has been difficult for a conventional shutter device to catch a robber even if a burglar invades during the operation, but the shutter device S of the present invention ensures high speed. Since it can be closed, the intruder can be prevented from entering the store, and furthermore, the robber can be captured in the store R or the like.

  And since it is possible to inform the existence of the shutter devices S, S2 that close at high speed to the robber, it is said that it will be attempted whether it is caught not only at night but also during the daytime business, even if the crime is committed by the robber. This will make it possible to realize this and dramatically improve the crime prevention effect.

  Furthermore, since the shutter panel 3 can be locked, it is possible to effectively capture a robber or prevent the intrusion of a robber and to fix the slats 2 and 2 in a closed state at a plurality of locations. In this case, the shutter devices S and S2 can be firmly maintained in the closed state, so that the capture of the burglar or the prevention of the intrusion of the burglar can be ensured.

  In the situation where there is no clerk at the store R such as at night or on holidays, if the shutter devices S and S2 are opened and closed by a human sensor such as an infrared sensor, the store or the like may be used for robbery at night or the like. It is also possible to use the shutter devices S and S2 for the purpose of capturing robbers against the intrusion into R.

  Further, since the shutter panel 3 slides along the arc-shaped hanger rail 4 and the guide rail 5, even when the doorway E of the store R or the like is arranged at the center between the pillars of the building or the like. It can be installed without difficulty in the store etc. R, can be installed without difficulty at the entrance E2 arranged at the corner, and the shutter devices S, S2 can be installed in the store R etc. in a space-saving manner. In addition, since the shutter panel 3 slides along the arc-shaped hanger rail 4 and the guide rail 5, even if the doors of the entrances E and E2 are inwardly-opening doors, the entrance and exit are provided after the shutter devices S and S2. Since there is no adverse effect that makes it impossible for people to enter and exit from E and E2, the versatility and practicality of the shutter devices S and S2 are improved.

  Furthermore, since the shutter device S is double-opened, the moving distance of the shutter panels 3 and 3 is shortened, so that the shutter device S can be closed at a higher speed.

  As for the locking of the shutter panel 3, the rod 93 is driven by the solenoid 94. Using this as a motor, the rotational movement of the motor is converted into the vertical movement of the rod 93 using an appropriate mechanism. It may be.
