Description

[Detailed description of the invention] 【Technical field] The present invention relates to an electric storage door for opening and closing a storage entrance. [Background technology]

Conventional electric garage doors have a structure in which the door body is opened and closed by a switch operating section attached to the wall or pillar of the garage. Therefore, in order to open or close the door, it is necessary to get out of the vehicle and move to the position of the switch operation portion each time, which is troublesome. For this reason, the inventors of the present invention considered operating the door body remotely using a remote controller, but the receiver that receives the signal from the remote controller and transmits the signal to the control device depends on the relationship with the drive device. In the same way, it needs to be built into the pillar. However, since the pillar supports the door body and requires strength, it is made of metal.If the receiver is built into this pillar, the metal pillar will cause damage to the area around the receiver. The remote controller is electrically shielded, causing problems such as signals from the remote controller not reaching the receiver or malfunction. Although this problem can be solved by attaching the receiver to the outer surface of the support, there is a problem in that the receiver is more likely to be tampered with by children or the like.

[Objective of the Invention 1] The present invention was made in view of the above-mentioned technical background, and its purpose is to make it possible to remotely control the door body even from inside a car, and to provide a metal strut. The objective is to ensure that the receiver built into the device can be operated using a remote controller. DISCLOSURE OF THE INVENTION The electric storage door of the present invention has an arm 3 that supports a door body 4.
The proximal end of the is rotatably supported by a metal support 1, and a drive device 5 for driving the arm 3 to open the door body 4 is provided in the support 1, and a portable remote control is provided. It is equipped with a receiver 8145 that controls and operates the drive device 5 in response to signals from the controller 44 and the remote controller 44, and this receiver 45 is built into the pillar 1 and is connected to the pillar 1.
The structure is characterized in that a portion corresponding to the built-in position of the receiving FI 45 is opened, and this opening 48 is not covered with anything other than a non-conductive lid 49. Since the door body 4 can be opened and closed by the remote controller 44, if the remote controller 44 is installed in the car, the door body 4 can be opened and closed from inside the car without getting out of the car. Furthermore, since an opening 48 is provided in the pillar 1 and this opening 48 is not covered with anything other than a non-conductive lid 49, the signal from the remote controller 44 is not shielded and passes through the opening 48 in the pillar 1. The receiver 45 can be reliably reached, and remote control by the remote controller 44 can be ensured. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows an example in which an electric storage door is installed at the entrance/exit of a parking space 2 formed in a wall 7 of a fence. On both sides of the parking space 2, pillars 1 are erected on the concrete floor 8, and on the inner side surfaces of both pillars 1, the base ends of arms 3, which are approximately V-shaped, are pivoted so as to be movable up and down. . The door body 4 is integrally fixed to the tips of the pair of arms 3, and as the arms 3 rotate, the door body 4 can be flipped horizontally upward from the closed state vertically on the Funkrete floor 8. It can be moved in the open state and in the open state. The door body 4 is opened W/I by rotating the arm 3 by a drive device 5, and the drive device 5 is housed inside one of the pillars 1. The structure of the drive device 5 is shown in FIGS. 3 to 6. A substantially fan-shaped cam 12 is disposed at the top of the narrow square cylindrical casing 9. This cam 12 has a structure as shown in FIGS. 7 and 8. A cylindrical shaft portion 60 is provided at the center of the cam 12, and the shaft portion 60 is rotated at the top of the casing 9. The cam 12 is movably supported on this shaft portion 6.
It can be rotated around 0. Shaft part 60
A square hole 59 is bored in the center of the arm 3, and a square bar-shaped rotating shaft 10 protruding from the base end of the arm 3 is inserted into the square hole 59 so as to rotate together with the cam 12. is maintained. Therefore, when the cam 12 rotates within the column 1, the arm 3 also rotates 1+7PW! kAMnMPjla
No. 1 foot;-ke b-pu cstk□ A connecting portion 19 for connecting with the link fil+t17 is protruded from the green on the front side of the cam 12, and a connecting portion 19 for connecting with the link fil+t17 is protruded from the center of the shaft portion 60 on the back side of the cam 12. An arcuate green 11 with a constant distance is formed, and a fitting hole 61 matching the shape and dimensions of the chain piece is recessed at the extended end of this green 11. If the chain piece at the end of the chain 13 is fitted into this fitting hole 61 from the side, the chain 13 will not come out of the fitting hole 61 even if the chain 13 is pulled.
The chain 13 is connected to the cam 12, and the chain 13, whose end is held by the cam 12, goes around the edge 11 and is suspended below the cam 12. Furthermore, chain 13
The upper end of the tension spring 14 is hooked to the pin 26 provided at the lower end of the casing 9.
The tension spring 14 pulls the chain 13 downward, which in turn biases the rotating shaft 10 in the direction of rotation shown in FIG. At this time, the chain 13 is always connected to the rotating shaft 1 by the cam 12.
Since it is maintained at a constant distance from 0, the length of the arm of the moment of tensile force of the chain 13 does not change as the rotating shaft 10 rotates, and the arm length of the moment arm of the chain 13 is always connected to the rotating shaft 10 via the chain 13. By keeping the moment of the working tension spring 14 at its maximum, the force of the tension spring 14 can be exerted efficiently at all times. Furthermore, a detected body 56 for pushing the sensing levers 62 of the limit switches LSO and LSC is attached to the back of the cam 12 with a screw, and the tip of the detected body 56 is connected to the cam 12.

As shown in FIGS. 10 and 11, the worm wheel 16 is provided with a through hole 64 in the center through which the fixed shaft 15 is inserted, and a helical threaded portion 65 that engages with the worm 23 is formed on the outer peripheral surface. , a plurality of screw holes 66 and a coupling hole 67 are provided surrounding the through hole 64. On the other hand, as shown in FIGS. 12 and 13, at the center of the clutch plate 57 is a through hole 69 through which the fixed shaft 15 is inserted.
A screw hole 70 for driving a screw is bored to surround the through hole 69, and a coupling protrusion 68 is protruded from the side facing the worm wheel 16. A clutch pawl 18a is formed in an annular shape on the side opposite to 17b. Then, the coupling protrusion 68 of the clutch plate 57 is fitted into the coupling hole 67 of the worm wheel 16, and a screw (not shown) is driven from the screw through hole 66 of the worm wheel 16 to the screw fixing hole 70 of the clutch plate 57. This allows the worm wheel 16 and the clutch plate 57 to be firmly integrated. The lower link 17b has a shape as shown in FIGS. 14 and 15, and has a through hole 71 at one end for inserting the fixed shaft 15, and an upper link 17a at the other end. a for joining
An inward hole 72 is bored, and the clutch plate 57 is provided around the through hole 71 on the surface facing the clutch plate 57.
The latch pawl 18b can be engaged with the clutch pawl 18a of

Further, the lower link 17b can not only rotate around the fixed shaft 15 (but also slide in the axial direction of the fixed shaft 15 along a key (not shown) fitted in the keyway 73, Lower link 17b
By sliding, the clutch pawl 18a of the clutch plate 57 and the clutch pawl 18b of the lower link 17b are engaged or disengaged, and the lower link 17
A spring 74 is interposed in a compressed state between b and the inner surface of the casing 9, and the elastic force of the spring 74 causes the clutch pawl 18b of the lower link 17b to mesh with the clutch pawl 18a of the clutch plate 57. . Thus, the clutch 18 is formed by the clutch plate 57 and the lower link 17b. The latch 18 and link mechanism 17 are constructed between the fan-shaped cam 12 and the worm wheel 16 as described above. This link mechanism 17 is composed of the above-mentioned upper link 17a and lower link 17b. That is, as shown in FIG. 4, the upper end of the upper link 17a is rotatably connected by a shaft 20 to a connecting portion 19 protruding from the outer periphery of the fan-shaped cam 12, and is inserted into the fixed shaft 15. The upper end of the lower link 17b and the lower end of the upper link 17a are rotatably connected by a shaft 21, and the upper end of the lower link 17b is also slidably connected to the shaft 21 like the lower end. Therefore, when the worm wheel 16 is driven, the lower link 17b is rotated via the clutch 18, and the cam 12 is further rotated via the link mechanism 17. Regarding the mechanism that moves the worm wheel 16 ffl,
This is shown in FIG. A bearing stand 32 is fixed to the casing 9 on the side of the worm wheel 16, and a worm 23 is attached to a worm shaft 33 which is pivotally supported on the bearing stand 32, and the worm 23 is attached to the worm wheel 16. are engaged. The bearing is connected to the motor 3 via the reduction gear 8!24 below the stand 32.

The rotation shaft 10 of the arm 3 is rotationally driven. At this time, the cam 12 is urged in the opening direction of the door body 4 by the tension spring 14, and most of 1a'ML of the door body 4 is biased by the tension spring 14.
4, a small motor with low torque can be used as the motor 34 for opening and opening the door body 4, and when lifting the door body 4, the motor 34 is used to move the rotation shaft 10. The door body 4 can be opened with a power smaller than the own weight of the door body 4 by rotating the door body. Conversely, when closing the door body 4, the motor 34 is reversely rotated to close the tension spring 14.
When the rotating shaft 10 is reversed against the spring force, the door body 4 is closed onto the concrete floor 8. Next, the means for disengaging the clutch 18 is shown in FIGS.
As shown in the figure. A clutch release lever 28 is rotatably mounted on the inner surface of the casing 9 with a pongee 22, and a locking pin 28a protruding from the lower end of the clutch release lever 28 is inserted into the id @ 75 of the lower link 17b. It is fitted in so that it can slide freely. An opening 2 is formed in the casing 9 at a portion corresponding to the upper end of the clutch release lever 28.
A set screw 30 is screwed into the upper end of the clutch release lever 28 from the outer surface side of the casing 9, and the set screw 30 is screwed into a screw hole 77 provided in the back plate 76 of the opening 29. By doing so, the clutch 18 can be locked in the engaged state. On the other hand, by removing the set screw 30 from the back plate 76, the clutch release lever 28 is rotated, and the lower link 17b is moved to the fixed shaft 15.
by sliding the clutch pawl 18b in the axial direction of the clutch plate 5.
The engagement can be released from the clutch pawl 18& of No.7. Therefore, in the event of an emergency such as an accident, the set screw 30 is removed from the back plate 76, the clutch release lever 28 is rotated to separate the clutch pawls 18m and 18b, and the clutch 18 is released.
6 and the lower link 17b becomes 717-, and the link mechanism 17 becomes able to move freely, allowing the door body 4 to be opened and opened by hand. However, normally, the clutch release lever 28 is fixed to the back plate 76 when the clutch 18 is engaged, and the opening 29 is covered with a protective cap 78 to protect the clutch release lever 28 from tampering, as shown in FIG. The drive device 5, which is integrally housed in the casing 9 as described above, is housed in the upper part of the support column 1 so as to be freely extracted. As shown in Fig. 16, the column 1 consists of a metal deep groove-shaped column main body 1a with a substantially U-shaped cross section and a metal shallow groove-shaped cover body 1b with a substantially U-shaped cross section. Engagement recesses 79 having a substantially C-shaped cross section are formed at both ends of 1a, and a lid 80 is provided, and the engagement protrusion 80 is inserted from the upper end of the engagement recess 79 and slid downward. By doing so, the engaging concave portion 79 and the engaging convex portion 80 can be engaged with each other as shown in FIG.
is starting to form. Furthermore, a plurality of protrusions 50 are provided on the inner surface of the support main body 1a, extending over the entire length of the top and bottom, and a substantially U-shaped groove 51 is recessed in the center of the protrusion 50, extending over the entire length of the top and bottom. has been done. This groove 51 is not open on the outer surface of the support main body 1a, and as shown in FIG. 17, uneven ribs 81 are provided along the entire length on both sides of the groove 51, so that the threads of a screw can engage with each other. A large number of them are formed. The upper end of the column 1 is covered with a column cap 31 made of synthetic resin as shown in FIG. The column cap 31 is supported on the column 1, and the piece 83 is attached by screwing the piece 83 downward from the inner surface of the column cap 31 toward the inner surface of the column 1. Therefore, by removing the column cap 31, the drive device 5 inside the column 1 can be inserted and removed from the upper end opening of the column 1 for inspection. Further, as shown in FIG. 2, the drive device 5 is controlled by a control device W135 also built into the support column 1, and the control device 35 includes three switch operation sections 6 and a remote controller. It is designed to be operated from 44 onwards. The indoor switch operation section 6 is indoor switch panels 6a and 6b provided on the back surface (or the inner surface) of the support column 1, and is provided on both support columns 1. Among these, the switch panel 6a provided on the support 1 on the side where the drive device 5 etc. are located has an open button 36.
An a1 close button 37a and a reset button 38 are provided, and this switch panel 6a is connected to the control device 35 by a connector 39. A switch panel 6b provided on the other pillar 1 is provided with an open button 36b and a close button 37b, and the switch panels 6a, 6b are connected to a terminal 40 of a control device 35. Moreover, the switch operation unit 6 on the outdoor side is a switch box 41 embedded in the wall surface 7 of the fence outdoors,
As shown in FIG. 25, this switch box 41 is provided with an open button 36c, a close button 37c, and a tumbler-type mode changeover switch 42, and the switch box 41 is a control device! It is connected to the terminal 40 of 35. Note that this switch box 41 is provided with simple locking means 43a, 43b so that it can be locked and prevented from being tampered with. Further, a plurality of remote controllers 44 of the remote control type may be used, and the remote controller 44 has a dark button 36d.
and a close button 37d. A radio wave signal is sent from the remote controller 44 to the antenna 84 of a receiver 45 built in the support column 1 and connected to the control device 35, and from the receiver 45 to the control device 3.
A signal is input to 5. This remote controller 44 is provided with an internal switch 85 for switching the signal mode, and an LED lamp 86 that lights up when the open button 36d or the close button 37d is pressed is provided on the surface. On the other hand, receive M8!
A combination switch 87 for switching the signal mode is also provided on the surface of the receiver 8!45, and only when the signal mode of the remote controller 44 and the signal mode of the receiver 45 match, the receiver 8! It is adapted to respond to the controller 44. Furthermore, the receiver 45
There is also an LED lamp 88 on the surface that lights up when it receives an open signal and an LED lamp 89 that lights up when it receives a close signal.
and is provided. Therefore, these LED lamps 8
6.88.89 of course serves as an operation signal, but is also used for operation confirmation and inspection. That is, when the open button 36d or the close button 37d is pressed, the LED lamp 8 of the remote controller 44
If 6 lights up, you can confirm the normal operation of the remote controller 44. At the same time, if the predetermined LED lamp 88 or 89 of the receiver 1fi 45 lights up, you can confirm the normal operation of the receiver 45. Therefore, the remote controller 44 and the receiver 8!45
It is difficult to determine which of the control device 35 and the control device 35 is malfunctioning. The control device 35 is built in below the drive device 5 in the support column 1, and the receiver 45 is built in below. The structure of the installation of the control device 35 and the receiver @ 45 on the inner surface of the column 1 is shown in FIG. 16, and is controlled by placing the back side on the protrusion 50 formed on the inner surface of the column 1! ! A gap 52 is formed between the back of the receiver 45 and the inner surface of the support 1, and the control device 3
The control device 35 or the receiver 8!45 is attached to the column 1 by driving a screw 53 into the groove 51 from the receiver 8!45. Therefore, since the column 1 does not require a screw hole for attaching the control device 35 or the receiver 45, the control device 35 or the receiver 45 will not be wetted by water that has entered the column 1 through the screw hole. In addition, since a gap 52 is formed between the inner surface of the column 1 and the inner surface of the column 1, the dew condensation water generated on the inner surface of the column 1 flows down along the gap 52, and is transmitted to the control device fi35 and the receiver l!4.
5 will not get wet. Therefore, the control device 35 and receiver 45 can be reliably protected from water. Further, since the control device 35 and the receiver 45 are attached to the groove 51, the driving position of the screw 53 is not restricted, and the height can be freely adjusted. And I received it! 145 and the control device 35 are connected by a signal cord 54. That is, signal code 54
is derived from the bottom surface of the receiver 45, and the signal code 5
A plug 58 at the tip of the controller 4 is inserted into a connecting portion 55 provided on the lower surface of the control device 35 to be connected. In this way, since the signal cord 54 comes out from the bottom of both the receiver 45 and the control device W135, even if water flows down along the surface, water will not enter the inside from the outlet of the signal cord 54. There is no such thing. *In addition, the case 35a of the control device 35 has a structure as shown in FIGS. An eaves portion 91 is provided in a protruding manner so as to surround the top and sides. Therefore, the water flowing down the surface of the control device 35 flows down to both sides along the eaves portion 91 at the lower part of the control device 35, so as not to wet the connection port 90, the terminal 40, and the connection portion 55. Further, as shown in FIG. 23, an eave-shaped @@92 is also projected above the combination switch 87 of the receiver 45, and the In part 92 allows water to flow into the combination switch 87.
This prevents it from entering the inside of the 7. Note that the hole 93 for screwing the receiver 45 to the protrusion 50 of the support 1 is a pothole hole, so after loosely driving the screw 53 into the protrusion 50, hook this hole 93 to the screw 53. This allows the receiver 8!45 to be easily fixed by tightening the screw 53. Furthermore, as shown in FIG. 2, the control device 35 includes a 100° volt power source 46 via an earth leakage breaker MCB, a three-phase AC motor 34 in the drive device 5, and a limit for detecting the fully open state of the door body 4. A switch LSO and a limit switch LSC that detect the fully closed state of the door body 4 are connected to each other, and an overload detection circuit 47 that detects when an abnormal load is applied to the door body 4 is provided inside the control device 35. Built-in. The limit switch LSO1LSC is attached to the side of the drive device 5 inside the column 1, as shown in FIG. The limit switch LSC is arranged above the cam 12,
The limit switch LSO is located behind the cam 12, and both limit switches LSO%LSC are attached with screws (not shown) inserted through the round hole 94 and the long hole 95, and when the screws are loosened, limit switch L
S.O. The LSC is designed so that the positions of the limit switches LSO and LSC can be adjusted 1111 times within the length range of the elongated hole 95 with the round hole 94 as the center, and are attached to the cam 12 when the door body 4 is fully open and fully closed. The position of the detected object 56 is adjusted so as to surely contact the sensing levers 62 of the limit switches LSO and LSC. For example, an electric circuit as shown in FIG. 29 is configured in the control device W135, and operates as shown in chart 70 of FIG. 30. The 70-chart in Figure 30 shows a remote controller, but as is clear from the circuit diagram in Figure 29, the pond switch panels 6a and 6b
The same applies to the case where the control operation is performed using the switch box 41 or the switch box 41, and the same applies to the case where these different pushing means are mixed at the same time. A case where the operation of this circuit is modified by the remote controller 44 will be described. First, assume that the door body 4 is closed. When the open button 36d of the remote controller 44 is pressed, the LE of the remote controller 44 is pressed.
The D lamp 86 lights up, a signal radio wave is transmitted, and the signal is received Is! When it reaches 145, the LED on the open side of reception 8!45
The lamp 88 lights up, the automatic return type switch 08Wd is turned on via the reception fi 45, the electromagnetic contactor M CI at address 1 is excited, and the contact M on the forward side of the motor drive circuit is turned on.
C is turned on, and the motor 34 of the drive device 5 rotates normally to open the door body 4. At the same time, a self-holding circuit is formed in the electromagnetic contactor MC2, and the opening operation continues even if the switch 03Wd is turned off. In this way, if no abnormal load is applied to the door body 4, the opening operation color tJLIJ+Wlk
A a*A+fllll&-1mm-Th y-Is
l Heat - 1 Twitch LSO is turned off, the self-holding circuit of the electromagnetic contactor MC, is released, the contact MC of the motor drive circuit is turned off, the motor 34 stops, and the door body 4 stands still. . However, when an abnormal load is applied to the door body 4 during operation and the overload detection circuit 47 outputs an output, the electromagnetic contactor MC2 at address 2 is excited and the contact MC of the motor drive circuit is turned off, so the motor 34 is immediately stops, and the door body 4 is stopped midway. In this state, the self-holding circuit of the electromagnetic contactor MC works, so after removing the cause of the overload, the remote controller 4
Even if the open button 36d or the close button 37d of 4 is pressed, each open/close switch 06Wd%C3Wd does not work. In this case, press the reset button 38 on the switch panel 6a provided on the pillar 1 to open the reset switch R3W,
It is necessary to release the self-holding circuit of the electromagnetic contactor MC1. This is to ensure safety in the event of an abnormality. After resetting,
When the open button 36d or the close button 37d of the remote controller 44 is pressed, a predetermined operation is performed. Also, when the close button 37d of the remote controller 44 is pressed during the opening operation, an automatic return switch C3Wd is activated via the receiver 45.
is turned on, the magnetic contactor MC2 at address 2 is excited, turning off the contact MC2 at address 1, and the magnetic contactor MC2 at address 1 is turned off.
Release the self-holding of C, and temporarily turn off the normal rotation side contact MC of the motor drive circuit, and then turn off the magnetic contactor MC at address 2.
2, the contact MC2 on the reverse side of the motor drive circuit
is turned on, the motor 34 is reversed, and the closing operation of the door body 4 is started. At the same time, the electromagnetic contactor MC at address 2 forms a self-holding circuit. The closing operation continues in this manner, and when the door body 4 reaches the fully closed state, the limit switch LSC turns off, releases the self-holding of the electromagnetic contactor MC2 at address 2, and turns off the contact MC2 of the motor drive circuit. The motor 34 is stopped and the door body 4 is kept stationary in the closed state. Note that if the open button 36d is pressed during the opening operation, or if the close button 37d is pressed during the closing operation, each operation continues. Furthermore, as shown in the lower half of the 70-chart in FIG. Next, the function of the mode changeover switch 42 provided in the outdoor switch box 41 will be explained. In FIG. 4, 03Wa is the open button 3 of the switch panel 6a.
oSWb is a switch that is turned on by operating the open button 36b of the switch panel 6b, and 08We is a switch that is turned on by operating the open button 36c of the switch box 41. C3Wa is a switch that is turned on by operating the close button 37a of the switch panel 6a, and cswb is a switch that is turned on by one operation of the close button 37b of the switch panel 6b.
Switches c are turned on by the close button 37c of the switch box 41, and are each provided in parallel with the switch C3Wd. The mode changeover switch 42 is the above-mentioned switch OS Wa or OS Wb. Switch SWm is turned on by operating six switches 5W111 inserted in series with 03Wc, C3Wa, C3Wb, and C8Wc. Therefore, if the mode changeover switch 42 is turned on, each switch 03Wa
, 08Wb, 08Wc, C3Wa. cswb%C8Wc is effective and both switch panels 6a. 6b, switch box 41 and remote controller 2
44, the door body 4 can be opened and closed in a multi-mode. On the other hand, when the mode selector switch 42 is turned to the off side, the switch SWm is turned off, and the switches OS Wa and OS Wb are turned off. 08Wc, C3Wa, C3Wb, and C3We are equivalent to the off state, the switch panels 6a, 6b and the switch box 41 become inoperable, and the remote controller 4
4 becomes a remote control only mode. Moreover, if the right two terminals 40 for the mode changeover switch 42 are short-circuited with a conductor among the terminals 40 shown in the MS2 diagram, the switch SWm is fixed in the on state.
It is possible to disable the mode selector switch 42 and prevent the switch to the remote control only mode due to mischief. If it is configured to be turned off, it can be used exclusively for remote control regardless of the switching of the mode selector switch 42 due to a short circuit of the terminal 40.The electric storage door configured as described above can be used for automatic entry and exit. In some cases, for example, the remote controller 44 is installed in a car, and the opening/closing operation of the door body 4 can be remotely controlled by sending a signal to the receiver 45 from inside the car without getting out of the car.
When the remote controller 44 is not installed in the vehicle, the door body 4 can be opened and closed indoors by pushing the switch panels 6a and 6b provided on the pillar 1 with the hand taken out from the driver's seat. In particular, since the switch panels 6a and 6b are provided on the pillars 1 on both sides, it is possible to drive the car regardless of whether it is a domestic car or a foreign car, or whether the front side of the car is facing indoors or outdoors. The door body 4 can be opened and closed from inside the car no matter which side the seat is on. Furthermore, when the remote controller 44 is not available, the switch box 41 is used to open and close the door body 4 outdoors. The switch box 41 can also be positioned at a height that can be reached from the driver's seat. It is not only cars that open and close this door body 4 to pass through, but also people, so in that case, people can pass through the switch panel 6a of the pillar 1,
6b or the outdoor switch box 41 to open and close the door body 4 to allow passage. An opening 48 for inspection is opened on the inner side of the support column 1 facing the path of the automobile, facing the built-in devices A such as the control device 35 and the receiver M@45. This makes it easier to perform maintenance and inspection. This opening 48 may be left open, but if it is closed with a removable lid 49, the M2S should not shield the radio waves entering the receiver 45 like those made of synthetic resin or glass. The material shall be non-conductive. Further, 1i49 is made transparent or semi-transparent so that the LED lamps 88 and 89 of the receiver 45 inside can be seen through the lid 49. Further, in the illustrated example, the lids 49 for the opening 48 on the control device 35 side and the opening 48 on the receiver 8!45 side are separate bodies, but they may be integrally closed by a single lid 49. Note that the above electric circuit is an example, and the design can be changed as appropriate. What is shown in FIGS. 31 to 33 is the other side of the present invention,
The limit switch LSO1LSC is integrally formed as a limit switch block B, and is detachably attached inside the casing 9. That is, a support plate 98 with a hole is projected from a mounting plate 97 having a horizontal holding piece 96 at the upper end, a nut 100 is welded to the hole in one of the support plates 98, and a bolt 101 is attached to the nut 100 and the support plate 98. The switch holder 102 is pivotally attached to the end of the bolt 101 using an E-ring or the like, and the switch holder 10
A protrusion 104 protruding from the mounting plate 97 is slidably fitted into the elongated hole 103 of the switch holder 103, and the switch holder 102 is structured so that the position of the switch holder 102 can be adjusted to the left or right by rotating the pole 101. Holder 102
The position of the limit switch LSC attached to the tip of the detection object 56 can be easily and precisely adjusted so as to perform a predetermined operation with respect to the detected object 56. Similarly, the position of the switch holder 102 to which the limit switch LSO is attached can be adjusted up and down by rotating a bolt 101 inserted into a support plate 99 having a hole in the mounting plate 97. Thus, in the limit switch block B configured as described above, the holding piece 96 at the upper end of the mounting plate 97 is removably attached to the horizontal piece 105 extending inward from the upper end of the casing 9 with screws 106. The limit switch block B can be taken out from the casing 9 for easy maintenance and inspection. The means for detecting the fully open state and the fully open state of the door body 4 is not limited to the limit switch as described above, but may also be an optical means such as an automatic switch or a magnetic means such as a magnet switch. It is not limited to waiting.

【Effect of the invention】

As described above, the present invention rotatably supports the base end of the arm that supports the door by a metal support, and a drive device for driving the arm to open and close the door is installed in the support. It is equipped with a portable remote controller and a receiver that receives signals from the remote controller to control the drive device, so the door can be opened and closed using the remote controller, and the remote controller can be installed inside the car. If you do so, you can open and close the door from inside the car without getting out of the car. In addition, this receiver is built into the pillar, and the part of the pillar corresponding to the position where the receiver is built is opened, and this opening is not covered with anything other than a non-conductive lid, so the signal from the remote controller is shielded. There is an advantage in that the receiver can be reliably reached through the opening in the support column without any interference, and that remote counterfeiting by a remote controller can be ensured. Furthermore, since the receiver is built into the support and can be removed, there is no risk of the receiver being tampered with by children or the like.
