Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of a portion of a gate driven by a drive device, in which a drive shaft rotates.

[Prior Art] A gate called an electric gate in which a door 7 is opened and closed by a drive device 2 has been conventionally known. As shown in FIG. 4, in this conventional electric gate, a door body 7 is rotatably supported by a hinge metal fitting 8 on a gate post 1 and a drive device 2 is attached to the outer surface of the gate post 1, and the drive device 2 and the door are attached. The body 7 is connected by the drive arm 5, and the drive device 2 is driven to open and close the door body 7 via the drive arm 5. However, in this conventional example, the drive device 2 is not only unpleasant because it protrudes outside and is exposed, but it is dangerous.

For this reason, the present inventor has installed the drive device 2 in the gate post 1 as shown in FIG. 5, provided the lateral groove 3 in the gate post 1, and installed the drive arm 5 rotated by the drive device 2 from the inside of the gate post 1 into the lateral groove 3. It was considered that the tip end portion of the drive arm 5 is connected to the door body 7 by projecting it through the outside.

[Problems to be Solved by the Invention] However, in the structure shown in FIG.
Although the drive device 2 does not project to the outside and is exposed by installing the inside, the appearance is improved as compared with the one shown in FIG.
A lateral groove 3 is formed in the gate post 1, and the inside of the gate post 1 can be seen from the lateral groove 3, and the appearance is not good at this point, and there is a risk that a hand or a finger may be put in the lateral groove 3, which is dangerous. .

The present invention was devised in view of the above-mentioned conventional problems, and the purpose thereof is that the drive device does not project to the outside and is exposed, and the inside of the pillar cannot be seen from the lateral groove of the gate pillar. Moreover, it is to provide a safe gate in which a hand or a finger cannot be inserted into the lateral groove.

[Means for Solving the Problems] In the gate of the present invention, a driving device 2 is arranged in a tubular pillar 1 and a lateral groove 3 is provided in a side surface of the gate pillar 1, and is rotated by the driving device 2. The drive arm 5 is projected from the inside of the gate pole 1 to the outside through the lateral groove 3, the shield member 6 for closing the lateral groove 3 is attached to the drive arm 5, and the door body 7 is connected to the tip of the drive arm 5. By adopting such a configuration, the above-mentioned object of the present invention is achieved.

[Operation] In the present invention, however, by disposing the drive device 2 in the cylindrical gate post 1, the drive device 2 does not project and be exposed to the outside. Also the drive arm 5
By closing the lateral groove 3 by the shielding member 6 provided in the horizontal groove 3, the driving device 2 and the like in the gate post 1 cannot be seen from the lateral groove 3 portion, and by blocking the lateral groove 3 with the shielding member 6, the lateral groove 3 can be easily touched. I couldn't insert my finger, so I became safe.

[Embodiment] The present invention will be described in detail below with reference to an embodiment shown in the accompanying drawings.

The gate post 1 has a tubular shape and its upper end is closed. A drive device 2 such as a motor is installed in the tubular gate pillar 1. A door body 7 is rotatably attached to the gate pole 1 via a hinge metal fitting 8. A lateral groove 3 is formed on a side surface of the gate pole 1, and a drive arm 5 that is rotated by the drive device 2 is used.
Is projected from the inside of the gate pillar 1 to the outside through the lateral groove 3.
A door 7 is connected to the tip of the drive arm 5. A shield member 6 for closing the lateral groove 3 is attached in the vicinity of the lateral groove 3 of the drive arm 5.
Although it moves together, the lateral groove 3 can be shielded in the entire movement range of the drive arm 5 (that is, the range from the fully opened state to the fully closed state of the door body 7).

2 and 3 show one embodiment of the shielding member 6 in detail. In this embodiment, the shielding member 6 is formed by forming a strip material into an endless shape, and fixing the shielding member 6 made of the endless strip material to the drive arm 5. A support member 10 is provided inside the gate post 1 so as to face the inner peripheral surface of the gate post 1 with a gap 9 therebetween, and the support member 10 is provided with an auxiliary lateral groove 11 corresponding to the lateral groove 3. Then, the shield member 6 made of the above-mentioned endless band material is located in the gap 9 between the support member 10 and the inner peripheral surface of the gate pole 1, and the drive arm 5 to which the shield member 6 is attached is attached to the auxiliary lateral groove.
11, to be inserted into the lateral groove 3. Then, the drive device 2 is driven to rotate the drive arm 5 to open and close the door body 7. In this case, the shield member 6 also moves in the gap 9 as the drive arm 5 rotates. The lateral groove 3 is always closed by the shielding member 6.

Here, the support member 10 may be attached to the outer peripheral surface of the gate pole 1 with a gap.

The shielding member 6 is made of rubber, synthetic resin, metal plate, or the like having flexibility.

[Advantage of the Invention] According to the present invention, the driving device is arranged in the tubular gate pillar as described above, the lateral groove is provided on the side surface of the gate pillar, and the driving arm rotated by the driving device is provided in the gate pillar. Since the door is connected to the tip of the drive arm by protruding it from the inside to the outside via the lateral groove, the driving device does not project to the outside and is not exposed, resulting in a good appearance and safety. Since a shielding member is installed to block the horizontal groove, the horizontal groove can be closed with the shielding member so that the drive device etc. inside the gatepost cannot be seen from the horizontal groove, resulting in a better appearance, and it is also possible to insert a hand or finger into the horizontal groove. It cannot be done and is very safe.
