Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a rake door provided at the entrance/exit of a lane, and more particularly to the structure of a rake door that is electrically driven to open and close.

[Conventional technology 1] In a conventional garage door, one end of the arm is connected to both sides of the door body, and the other end of the arm is rotatably connected to the upper end of a column whose lower end is buried in the ground using a rotating shaft. It was designed to be closed when the door body was turned vertically, and opened when the door body was rotated upward and horizontally. In order to be able to open and close the door electrically, the rotating shaft is driven by a motor.

[Issue to be solved by the inventionffi] In the above conventional example, the door can be opened and closed electrically, but there is a problem that the door moves if force is applied inadvertently to the door in the closed or open state. There is also the problem that in order to prevent accidental movement, the lock bin must be inserted between the arm and the support, and a separate locking operation must be performed to lock it. was there.

The present invention has been made in view of the above points, and an object of the present invention is to be able to lock the door body so that it does not move in the closed state or the open state, and moreover, to easily lock it by electrical means. is to provide a storage door.

[Means for Solving the Problems] To achieve the above object, the present invention provides a storage door in which one end of an arm 2 is connected to each side of a door body 1, and the other end of each arm 2 is rotatably connected to a support 3. Connected to the rotating shaft 4 attached to the
In a galley door that is in a closed state when the door body 1 faces vertically and in an open state when the door body 1 faces upward and horizontally, a driven gear 5 of a rotating shaft 4 is integrally provided within a support 3. At the same time, a drive gear 8 driven by a motor 7 via a reduction gear 8!6 is meshed with the driven gear 5, so that when the door body 1 is in a closed state facing the vertical direction and when it is open when the door body 1 is facing the horizontal direction. The present invention is characterized in that a locking body 9 is provided which locks into the locking grooves 11a+11b of the driven gear 5 in the state, and the engagement and disengagement of the locking body 9 is controlled by a solenoid 10.

[Operation] By driving the motor 7, the rotary shaft 4 is driven via the deceleration 1s16, the drive gear 8, and the driven gear 5, and the door body 1 can be electrically driven to open and close. Further, the driven gear 5 can be locked by controlling the locking body 9 with the solenoid 10 in the closed state and in the open state.

[Example] Reference numeral 3 indicates a hollow pillar, and as shown in the first frame, a pair of pillars 3 are erected so as to face each other. Reference numeral 1 denotes a door body, which is formed in a grid shape. Reference numeral 2 denotes an arm, which is configured in a V-shape with an upper arm 2a and a lower arm 2b. One end of the upper arm 2a is connected to the upper ends of both sides of the door body 1, and the upper arm 2a is orthogonal to the door body 1.

One end of the lower arm 2b is connected to the middle part of both sides of the door body 1, and the other end of the upper arm 2a and the other end of the lower arm 2b are integrated. A rotary shaft 4 is inserted horizontally into the upper end of the support column 3 so as to be freely rotatable, and an arm 2 is connected to the rotation shaft 4 outside the support column 3. A driven gear 5 made of a bevel gear is integrally attached to the rotating shaft 4 within the support 3, and a drive gear 8 made of a bevel gear is meshed with the driven gear 5. A speed reducer 6 is placed below the drive gear 8, and a motor 7 is placed below the speed reducer 6, so that the rotation of the motor can be decelerated at speed 6 and transmitted to the drive gear 8. ing. A pair of locking grooves 11a are provided on the outer periphery of the driven gear 5.

11b are formed at intervals of approximately 90° in the circumferential direction. A lock body 9 is attached to the outer periphery of the driven gear 5 so as to be rotatable around the pongee 12, and the lock body 9 is provided with the locking groove 11.
A locking portion 13 that can be locked to the a and llb is provided. The lock body 9 is provided with a tension spring 14 that urges the locking portion 13 to rotate in a direction in which it locks in the locking grooves 11a and llb. A solenoid 10 is provided near the lock body 9 to rotate the lock body 9 against the spring force of a tension spring 14. Further, a manual lock release rod 15 is slidably mounted above the driven gear 5.
A protrusion 16 protruding from the outer periphery of the holder 5 is fitted along an L-shaped id groove 17. Then, when the operating portion 18 at the base end of the manual lock release rod 15 is pushed and rotated with a screwdriver or the like to engage the protrusion 16 with the engagement portion 17a of the idle groove 17, the tip of the manual lock release rod 15 becomes the lock body. 9
is rotated against the tension spring 14 to remove the locking portion 13 from the locking grooves 11a and llb. Further, the pillar 3 is provided with a first micro switch 20 and a second micro switch 7 21 at the top and bottom, and the driven gear 9 is provided with the first micro switch 20 and the second micro switch 21, respectively.
．． Dog 2 operating the second microswitches 20 and 21
2.23 is provided. Further, a gas spring 27 is installed inside the column 3, and the upper end of the gas spring 27 is rotatably connected to a drive arm 28 fixed to the rotating shaft 4.

A cap 24 is attached to the upper end of the column 3.

However, when closing the door body 1 from the state shown in FIG. 2(,) to the state shown in FIG. 2(b), if the closing switch is turned on by operating the operation button 26 or by operating the remote control, /id 10 is turned on, lock body 9 rotates in the direction of arrow A in Fig. tJS4, locking portion 13 comes out of locking groove 11a, and the lock is released.

The motor 7 is then rotationally driven, the drive gear 8 is rotationally driven clockwise via the reducer 6, and the driven gear 5 is rotationally driven in the direction of the arrow in FIG. At the same time, the dog 22 fixed to the driven gear 5 rotates, and the dog 22 moves to the first position.
Away from the micro switch 20, the driven gear 5
At the same time, the fixed drive 7-arm 28 rotates, and the door body 1 rotates via the rotating shaft 4 and the arm 2, thereby closing the door body 1. When the drive arm 28 and the driven gear 5 rotate 90 degrees and the door body 1 is closed, the dog 23 hits the second micro switch 21 and the rotation of the motor 7 is stopped. At the same time, the solenoid 10 is turned off, the lock body 9 is rotated in the direction of the arrow C in FIG. 4 by the spring force of the tension spring 14, and the locking portion 13 is locked in the locking groove 11b. Further, when opening the door body 1 from the state shown in FIG. 2(b) to the state shown in FIG. 2(a), when the opening switch is turned on by operating the operation button 26 or operating the remote control, the solenoid 1 is turned on, the lock body 9 rotates in the direction of arrow A in FIG. 4, the locking portion 13 comes out of the locking groove 11b, and the lock is released. The motor 7 is then rotated in the opposite direction to the above, the drive gear 8 is rotated counterclockwise via the reduction gears 8 and 6, and the driven gear 5 is rotated in the two directions indicated by the arrows in FIG. At the same time, the dog 23 is fixed to the driven gear 5.

[Effects of the Invention] As described above, the present invention has a rotating shaft driven gear integrally provided within the support, and a drive gear driven by a motor via a reduction gear is meshed with the driven gear, so that there is no connection from the motor to the reduction gear. Of course, the door can be opened and closed electrically by rotating the rotating shaft through the drive gear and driven gear, and it can also be opened and closed when the door faces vertically, and when it is open when the body faces horizontally. Since a locking body is provided that locks into the locking groove of the driven gear, the door can be locked to prevent it from moving in the closed and open states, preventing the door from opening or closing due to inadvertent external force. Moreover, since the engagement and disengagement of the lock body is controlled by a solenoid, locking and unlocking can be easily performed electrically.
