Abstract

PURPOSE:To meet needs without trouble even when an electric motor mechanism is out of order by a method in which when a connecting pin detachably set between a drive lever and a worm wheel is set, opening or closing is made electrically, and when the connecting pin is removed, opening or closing is made manually. CONSTITUTION:One ends of arms 2 are connected to both sides of a door 1, and the other ends are pivotally supported on a rotary shaft 4 in such a way as to the door 1 to rotationally move laterally and vertically for opening or closing the door 1. A motor 6 is operated, and the arms 2 are operated through a worm 7, a worm wheel 5, and drive levers 8 for electrically opening or closing the door 1. When the electric motor mechanism is out of order, a connecting pin 9 inserted between the levers 8 and the worm wheel 5 is removed for freeing the movement of the arms 2 in order to manually open the door 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the structure of a garage door provided at the entrance/exit of a galley.

[Prior Art] In the conventional galley door, as shown in Fig. 4, one end of the arm 2 is connected to both sides of the door body 1, and an arm is attached to the upper end of the support 9 whose lower end is buried underground. It is formed by connecting the other ends of 2 rotatably with a rotating shaft 4, and is closed when the door body 1 is turned vertically, and opened when the door body 1 is rotated and turned horizontally upward. It had become.

[Problems to be Solved by the Invention] In such a conventional example, the door body 1 is opened and closed manually, so when opening the door body 1, the heavy door body 1 must be lifted and opened, and the door body 1 must be closed again. There is a problem that the door body 1 must be supported to close it because there is a risk that the door body 1 will forcefully close due to its own weight if the hand is released. In order to eliminate this problem, there are models that are electrically driven using a motor, but in the case of electrically driven models, if the drive mechanism breaks down, the door body 1 cannot be moved manually and cannot be opened or closed. was there.

The present invention has been made in view of the above points, and an object of the present invention is to provide a garage door that can be electrically opened and closed without requiring any effort, and that can also be opened and closed manually when the mechanism fails. There is something to do.

[Means for solving the problem 1 In order to solve the above problems, the garage door of the present invention has three pillars.
A worm wheel 5 is rotatably attached to a rotating shaft 4 rotatably attached to the upper part of the support column 3, and a worm 7, which is rotationally driven by a motor 6 disposed in the support column 3, is meshed with the worm wheel 5 and rotated. A driving punch 8 attached to the shaft 4 and the arm 2 are connected, and the driving punch 8 and the worm wheel 5 are connected to each other.
A connecting bottle 9 is attached between the two and can be freely inserted and removed.

[Action 1] When the drive punch 8 and the worm wheel 5 are connected by connecting the connecting bottle 9, the power is transmitted to the motor 6, the ohm 7, the worm wheel 5, the drive punch 8, and the arm 2 in this order, and the door body 1 is electrically powered. The door body 1 can be opened and closed manually, and by removing the connecting pin, the drive punch 8 rotates freely relative to the worm wheel 5, and the door body 1 can be opened and closed manually.

[Embodiment] Reference numeral 3 indicates a hollow support column, and as shown in FIG. 1, a pair of support columns 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 composed of an upper arm 2a, a lower arm 2+3, and a connecting portion 2c. 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 connected to the upper ends of both sides of the door body 1.
A is orthogonal. One end of the lower arm 2b is connected to the central portions on 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 at a connecting portion 2c.

As shown in FIG. 2, a rotary shaft 4 is rotatably mounted on the upper part of the support column 3, and a worm wheel 5 is rotatably mounted on the rotary shaft 4. A drive shaft 10 is disposed vertically so as to be orthogonal to the rotation shaft 4, and the upper and lower ends of the drive shaft 10 are rotatably supported by bearings 11. A motor 6 with a speed reducer is disposed below the drive shaft 10, and an output shaft 12 of the motor 6 is connected to the drive shaft 10. A worm 7 is integrally provided on the drive shaft 10, and the worm 7 and the worm wheel 5 are meshed with each other. A driving punch 8 is arranged on the rotating shaft 4 in parallel with the worm wheel 5, and the driving punch 8 is fixed to the rotating shaft 4. The drive punch 8 and the worm wheel 5 are provided with bottle holes 13.14, and the connecting bottle 9 is inserted into and removed from the bottle holes 1.3.14 at will. The rotating shaft 4 integrated with this driving punch 8
The connecting part 2c of the arm 2 is connected outside the support 3,
The arm 2 is driven integrally with the driving punch 8.

However, while the door body 1 is in the closed state facing vertically, the motor 6
When driven, the arm 2 is driven via the drive shaft 10, the worm 7, the worm wheel 5, the drive punch 8, and the rotating shaft 4, and the door body 1 is driven upward, so that the door body 1 faces upward and laterally. It will be opened like this. When the motor 6 is driven in the opposite direction to that described above while the door body 1 is in an open state facing sideways, power is transmitted in the opposite direction to that described above, and the door body 1 can be closed so as to face vertically. Furthermore, when the connecting bottle 9 is removed, the driving punch 8 can freely rotate relative to the worm wheel 5.
It can be separated from the transmission system of the motor 6 and the door body 1 can be opened and closed manually. If the door body 1 is to be opened and closed only manually, use the support post 3.
If a gas spring 15 is installed inside the door and the gas spring 15 is connected to the connecting hole 16 of the driving punch 8, the spring 15 can assist in opening and closing the door body 1 when opening and closing it manually. and close slowly.

Further, FIG. 3 shows another embodiment. Rotating shaft is bearing17.
The drive punch 8 is rotatably attached to the rotating shaft 4 via a bearing 19. The driving punch 8 and the worm wheel 5 are connected by a connecting pin 9 which can be inserted and removed freely. A connecting portion 2c of the arm 2 is connected to the driving punch 8. This embodiment also operates in the same way as the above embodiment.

[Effects of the Invention] As described above, the present invention includes a worm wheel rotatably mounted on a rotating shaft rotatably mounted on the upper part of a support, and a worm that is rotatably driven by a motor disposed within the support. The arm is connected to the driving punch which is meshed with the wheel and attached to the rotating shaft, and the connecting bottle is detachably installed between the driving punch and the worm wheel.
When the motor is driven with the connecting bottle connected, ohm,
The door body can be opened and closed by electrically driving the door body through a worm wheel and a driving punch, and the door body can be opened and closed without requiring any effort, and by removing the connecting bottle, the driving punch can be changed to a worm wheel. On the other hand, the door can be rotated freely and the door can be opened and closed manually, so it can be used even if the electric suspension system breaks down.

Claims (1)

[Claims] [1] One end of each arm is connected to both sides of the door body, and the other end of each arm is rotatably attached to a support, so that when the door body is facing vertically, it is in the closed state, and when the door body is facing upward and horizontally. For garage doors that are oriented in an open state, a worm wheel is rotatably attached to a rotating shaft rotatably attached to the upper part of a support column, and the worm is rotationally driven by a motor installed within the support column. The garage door is constructed by meshing with the worm wheel, connecting a drive rod mounted on a rotating shaft with the arm, and attaching a connecting pin between the drive rod and the worm wheel so as to be freely insertable and removable.
