Description

  The present invention relates to a transmission for obstacle detection in an architectural shutter device for transmitting an obstacle detection signal when an obstacle detection is performed in a process of closing a shutter curtain in an electrically operated shutter device for building. It relates to the waterproof structure and waterproof method of the machine.

In general, a motorized architectural shutter device provided for opening and closing an opening such as an entrance of a building has an opening when a shutter curtain is wound around a winding drum by forward and reverse driving of an opening and closing machine and unrolled. When the obstacle detection switch (seat plate switch) detects an obstacle, the seat plate at the lower end of the shutter curtain abuts against the obstacle in the process of closing the shutter curtain. An obstacle detection signal may be transmitted from a transmitter provided on the seat plate, and the switchgear may be urgently stopped based on the reception of the obstacle detection signal by the receiver. In such an architectural shutter device, the seat plate provided with the transmitter is located closest to the floor when the shutter curtain is fully closed, particularly when the shutter curtain is a pipe like a grille shutter. Water such as rainwater is likely to be directly exposed from the outside, and high waterproofness is required.
By the way, the transmitter may break down for some reason, and in this case, if the cause of the breakdown is investigated and the part which is broken down (for example, the substrate) is replaced, the maintainability is bad. Therefore, in such a case, maintenance is improved by replacing the entire transmitter. For this reason, although the cable drawn out from the obstacle detection switch and the cable drawn out from the substrate side are detachably connected via the connector, it is not preferable that the connector get wet, so there the transmitter It is known that a connector chamber is provided in such a way that the connector chamber is made waterproof and the connector is protected from water (see, for example, Patent Document 1).

However, in the prior art, a U-shaped groove is formed in the wall constituting the connector chamber, and a cable drawn from the obstacle detection switch is fitted in the groove and the entire inner peripheral surface of the connector chamber is formed. A support portion lower than the open end of the connector chamber is provided, and in a state where the cable is fitted in a semicircular groove portion provided in the support portion, a packing is applied so as to abut the support portion. By covering the body, the opening of the connector chamber is sealed in a waterproof manner. In this case, the cover has a semicircular groove whose tip is semicircular in order to pass the cable half protruding from the groove of the wall. In the packing, a semicircular groove is provided to pass through the cable half protruding from the groove of the support.
By the way, when the lead wire connected to the switch is directly exposed, the cable pulled out from the obstacle detection switch is likely to be broken due to the lead wire coming in contact with foreign matter, and the lead wire therefore In order to cover in a loose fit, a flexible cylindrical covering material is used. In this case, assuming that the covering material abuts on the semicircular groove and covers the covering material, the covering material is flexible so that it is easily bent and a gap is formed between the covering material and the groove so that water may infiltrate from here. . Therefore, it is proposed that the cover be forcibly covered by the groove as if the cover is crushed, but in such a case, the cover will be bent and deformed by being crushed, but water is There is a fear of infiltrating. In addition, although it is conceivable to waterproof using packing, the packing is not in close contact only by coming into contact with the cable, and in any case there is a problem that it is not sufficient as a waterproofing measure. There is a problem to be solved.

The present invention has been made to solve these problems in view of the above situation, and the invention of claim 1 is in contact with an obstacle on the seat plate at the lowermost end of the shutter curtain. And an obstacle detection transmitter for outputting an obstacle detection signal according to the detection of the obstacle, and the obstacle detection response is made based on the input of the obstacle detection signal.

Hereinafter, embodiments of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a motorized architectural shutter device, the shutter device 1 includes a shutter curtain 2 for opening and closing an opening, a winding drum 3 for winding the shutter curtain 2, Guide rails 4 provided on the left and right of the opening to guide opening and closing of the shutter curtain 2 unwound from the winding drum 3, an opening and closing machine 5 for rotating the winding drum 3 forward and reverse, opening and closing the opening and closing machine 5 It is as in the prior art that it is configured by various member devices such as a switch device (push button switch) 6 for performing the stop operation.
Incidentally, the present invention can be adopted to any of various types of architectural shutter devices such as a weight shutter device, a lightweight shutter device, and a grille shutter device.

  The shutter curtain 2 is formed by connecting a plurality of slats 2a in a single plate shape, and the lowermost seat plate 7 of the shutter curtain 2 is formed of a substantially wedge-shaped upper half 7a and a substantially wedge-shaped lower plate In the lower half 7b, both leg pieces 7d are loosely fitted between the two legs 7c of the upper half 7a, and the upper piece 7e of the lower half 7b is the upper half. By locking the lower piece 7f from the upper side from the upper side, the upper half 7a can be moved up and down in a state in which the lower side is prevented from falling off.

  A plurality of obstacle detection switches 8 are provided on the upper side piece 7g of the seat plate upper side half 7a so as to face the lower side piece 7h of the lower side half 7b at appropriate intervals in the left-right direction. Causes the obstacle detection switch 8 to be disposed between the upper and lower halves 7a and 7b, but the obstacle detection switch 8 is fixed to the upper half upper piece 7g via the screw 8a. And 8a, a detection unit 8d swingably provided to the main body 8b via a support shaft 8c, and a bullet (not shown) for biasing the detection unit 8d downward. ing. In each of the obstacle detection switches 8, the detection portion 8d is connected in series through the connection member 8e, and the lower half 7b is a floor surface or the like when the shutter curtain 2 is fully opened or closed. When the lower half 7b is suspended by its own weight in a state in which the lower half 7b is not in contact with an obstacle, the lower half lower piece 7h is separated from the detection portion 8d. In such a thing, when the lower half 7b is in contact with an obstacle during the closing operation of the shutter curtain 2 and the downward movement of the lower half 7b is restricted, the lower half 7b is the upper side. The relative movement of the lower part 7a relative to the half 7a causes the lower half lower piece 7h to abut on the detection part 8d and push it upward. Incidentally, in the present embodiment, the relative upward movement of the lower half 7b with respect to the upper half 7a is, for example, an oblique one in which the obstacle is biased to the left or right side and the biased side Even when the detection unit 8d is pushed up, as described above, since the detection unit 8d is connected in series by the connecting member 8e, a detection operation is performed in which all the detection units 8d are pushed up, thereby performing the detection operation It is advised that there is no leakage of

  On the other hand, one of the obstacle detection switches 8 is provided with a micro switch (normally ON contact, b contact) 9 as a sensor switch in the main body 8b. The micro switch 9 is a detection unit 8d. In the state of hanging down due to the biasing force of the bullet, the operation portion (not shown) provided on the detection portion 8d is pressed into contact with the switch bar 9a of the micro switch 9, and the switch bar 9a is pushed. As a result, the microswitch 9 is maintained in the ON state. On the other hand, as described above, when the detecting portion 8d is pushed up against the biasing force of the bullet 8e by coming into contact with the obstacle, the operating portion 8f is separated from the switch contact 9a and the switch bar 9a is A biasing operation of a bullet (not shown) is performed to perform a separation operation, whereby a detection operation of switching the microswitch 9 to OFF is performed, whereby an obstacle detection signal is output.

  A lead wire 10a is drawn out from the micro switch 9, and a cylindrical covering material 10b is fitted on the lead wire 10a in a loose fitting manner, whereby the cable (wiring) 10 of the present invention is obtained. It is configured. The cable 10 passes through the through hole 7i provided in the upper half upper piece 7g to reach the upper surface of the upper half upper piece 7g.

  Reference numeral 11 denotes a transmitter for transmitting an obstacle detection signal. The transmitter 11 is mounted on the slat 2a in a vertical piece 7j erected from the upper half 7g of the seat plate 7 through the screw 11a. Although fixed together with the seat bar 2b to be connected, the transmitter 11 is configured to include a case main body 11b opened at the vertical piece 7j side and a lid 11c covering the opening side. In the transmitter 11, a battery chamber 11d in which the battery 12 is assembled, a substrate chamber 11e in which the substrate 13 is assembled, a connector half 14a provided at the tip of the cable (specifically, the lead wire 10a) 10 and the substrate 13 A connector chamber 11f is provided for storing the connector 14 in which the halves of the connector half 14b provided at the tip of the lead wire 13a pulled out from the housing 14 are detachably connected. When the obstacle detection signal is input from the obstacle detection switch 8 as described above, the transmitter 11 receives the obstacle detection signal from the light emitting member (for example, a light emitting diode that emits far-infrared light) provided on the substrate 13. When the receiver 17 provided in the magsa unit 16 above the opening receives and outputs this obstacle detection signal, the received signal is inputted to the control unit 18, and the opening / closing machine 5 performs closing operation. When there is an emergency stop signal and an obstacle avoidance operation signal set in advance is output to the switchgear 5, the necessary obstacle detection response can be performed in this way. ing. In the present embodiment, the lead 13a on the substrate 13 side is not provided with a covering material, but may of course be covered with a covering material if necessary.

The connector chamber 11f is formed by making the lid 11c concave toward the case main body 11b, but a through hole 11h through which the substrate side lead wire 13a penetrates is formed in the bottom portion 11g of the connector chamber 11f. Thus, the board-side connector half 14b is accommodated in the connector chamber 11f.
On the other hand, the cable 10 drawn from the obstacle detection switch 8 is led from the end of the transmitter 11 to the connector chamber 11f so as to run in the concave groove 11i formed in the lid 11c, and provided at the tip The transmitter-side connector half 14a is connected to the substrate-side connector half 14b in the connector chamber 11f, and after the connector 14 is connected in this manner, the screw receptacle 11j provided protruding from the connector chamber bottom 11g The partition 11k abutted against the front end portion of is fixed via a screw 11p. In addition, a through hole 11m for penetrating the cable 10 is formed in the partition body 11k, and the light emitting member 15 is opposed to the light emitting window 11o formed of a translucent material, whereby an obstacle is caused. The detection signal is transmitted through and is received by the receiver 17. Incidentally, the partition 11k can be formed of an appropriate material such as a resin material, a metal, or a paper. Further, the partition 11k is not limited to one fixed to the screw receiver 11j via the screw 11p, for example, a support (for example, at least two) capable of planarly supporting the partition 11k from the connector chamber bottom 11g or the peripheral wall A support and a cross-shaped support are provided in a protruding manner, and the partition 11k is abutted and supported by the support, or an opposing distance between a plurality of peripheral walls (at least two surfaces) of the connector chamber 11f is described later. A step is formed such that the bottom side half S1 side to be formed is narrow and the opening side half S2 is wide, and the partition 11k is abutted and supported on the step so that the screw is not fixed. Can also be implemented.

  Thus, when the connector 14 is connected by the connector chamber 11f and the connector chamber 11f is closed by the partition 11k, the connector chamber 11f is formed by the partition 11k and the bottom half portion S1 in which the connector 14 is disposed. It is divided into an opening side half portion S2, but after wiring, the opening side half portion S2 is filled with a waterproof material (putty, caulking material) 19 having a non-hardening soft viscosity. Since the filled waterproof material 19 has soft viscosity, the waterproof material 19 has a peripheral wall of the opening side half S2, a surface on the opening side half S2 side of the partition 11k, and a circumference of the cable 10. It adheres well to the surface (It adheres well along the deformed surface as it deforms under the filling pressure when the covering material 10b is filled with the waterproof material 19), and the opening side half S2 has no gap. The bottom half portion S1 in which the connector 14 is accommodated is sealed, and thereby the waterproof function can be enhanced.

  In the present embodiment configured as described above, the obstacle detection switch 8 detects that the seat plate 7 at the lowermost end of the shutter curtain is in contact with an obstacle, and the obstacle detection with the obstacle detection. A transmitter 11 for detecting an obstacle that outputs a signal is provided, and an obstacle detection response is made based on the input of the obstacle detection signal, and the obstacle detection is performed while the shutter curtain 2 is closed. If this is done, the closing operation of the shutter curtain 2 will be stopped urgently, and then the necessary obstacle avoidance operation will be performed. In this case, the concave shape is fitted on the lid 11 c of the obstacle detection transmitter 11 The connector chamber 11 f forms the connector chamber 11 f, and the connector chamber 11 f is connected to the bottom side half portion S 1 in which the connector 14 is installed and the case connected to the obstacle detection switch side. The bottom part is divided into an opening side half part S2 to be pulled in, and the space is divided by a partition 11k, and the opening side half part S2 is filled with a waterproof material 19 to ensure waterproofness, so the bottom part The waterproof material 19 does not enter the side half S1 and is not attached to the connector 14, and the connector 14 can be protected.

  Moreover, since the waterproofing material 19 is soft and viscous, even when the covering material 10b of the cable 10 is deformed when the opening side half portion S2 is filled, the waterproofing material 19 adheres in a state along the deformation well. As a result, the water resistance of the connector 14 can be protected.

  Moreover, since the waterproofing material 19 is non-hardening, when maintenance such as replacing the transmitter 11 is performed, the partitioning body 11k is exposed by coming out from the opening side half portion S2, and the screw 11l is removed. If the partition 11k is taken out, the connector 14 will be exposed, and the connector 14 can be removed and the replacement work of the transmitter 11 can be simplified.

  The present invention is not limited to the above embodiment. For example, the seat plate is an inverted T shape, and a tape switch is provided on the lower surface (bottom surface) of the seat plate as an obstacle detection switch. Can also be implemented. The connector chamber can of course be provided not on the lid side but on the case body side.

  The present invention can be used as a transmitter for obstacle detection in an architectural shutter device for opening and closing an opening.
