issue).

``Problems that the invention aims to solve'' However, since gates are installed outdoors, the driving part must be protected from wind and rain, and the movable parts must be kept as much as possible from exposure for safety reasons. Furthermore, it is desirable that the installation and maintenance of the gate be easy.

However, as shown in Figure 7, the drive unit is buried underground, which requires troublesome installation work and maintenance, and in the systems shown in Figures 8, 9, and 10, the moving parts are exposed. There were problems in that it was dangerous and the installation work was troublesome.

On the other hand, if the driving device is housed inside the gatepost as shown in FIG. 6, the above problems can be solved, but there are some difficulties in the structure inside the gatepost and the installation of the door.

"Means for Solving the Problems" The present invention was made in order to solve the above-mentioned problems.
Attach the door 55 with the drive device 35.
In the automatic gate which is opened and closed by
At the same time, a driven-side rotating shaft 47 that is transmitted by the rotating shaft 44 of this drive device 35 is attached, and this support 34a, the driving device 35, and the driven-side rotating shaft 47 are connected to the notch 38 for hinge protrusion. , 39 is fitted and covered with a gatepost cylinder 37, and one end of the hinge parts 40, 41 can be detachably attached to the driven side rotating shaft 47 side by passing through the hinge protruding notches 38, 39. Installation, hinge protrusion notches 38, 3 of the gate post cylinder 37 on the other end side of the hinge parts 40, 41
This is a gate mounting device characterized in that the door 55 is mounted on a protruding portion from the gate 9.

"Function" The hinge parts 40, 4 are attached to the pillar 34a inside the gate post 34.
The drive device 35 is installed in advance with the drive device 1 removed. A decorative gatepost cylinder 37 is fitted and covered on this. Then, the hinge protrusion notches 38 and 39 formed in the cylinder body 37 coincide with the hinge part attachment parts, so the hinge parts 40 and 41 are attached by passing through the notches 38 and 39 from the outside. Then, the door 55 is fixed to the hinge parts 40, 41 to complete the installation.

Installation and maintenance of the door 55 and drive unit 35 are easy,
Moreover, it is highly safe because no moving parts are exposed.

"Embodiment" Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 5.

34 is a gatepost, and this gatepost 34 has four pillars 34a made of angle wood.
A drive part 35 is attached to the lower part by a, and a hinge receiver 36 is attached to the upper part, and a decorative square cylinder body 37 is fitted so as to cover the drive part 35 and the hinge receiver 36. After that, the hinge parts 40 and 41 are attached to the drive part 35 and the hinge receiver 36 from the notches 38 and 39.
Connect by screwing one end of the two together.

The motor shaft 42 of the drive section 35 is coupled to a reducer 43, and a rotating shaft 44 on the drive side of the reducer 43
A link 46 with a guide roller 45 is connected to the link 46 . Further, a link 49 having a guide groove 48 is connected to the rotating shaft 47 on the driven side. The other end of this link 49 has the hinge portion 40
One end is screwed together, and the other end protrudes outward.

A support stand 5 that supports the rotation shaft 47 on the driven side
On the bottom side of 0, there is a link 49 as shown in Figure 5.
A fan-shaped recess 51 is provided to restrict the movement range of the
Both inner edges serve as stoppers 52, 52 of the link 48. Further, on the upper surface side of the support base 50, there is a recess 5 that restricts the movement range of the link 46, as shown in FIG.
3 are provided, and both inner edges serve as stoppers 54, 54 of the link 46.

A gate 55 is attached to the hinge parts 40, 41 with screws 59, with metal fittings 56, 57, 58 abutting against them.

In such a configuration, the rotation of the drive unit 35 is decelerated by the reducer 43, and the rotation shaft 44 on the drive side is
The link 46 rotates to the right in FIG.
The rotation of one link 46 causes the guide roller 45 to
moves while sliding in the guide groove 48 of the other link 49, so the other link 49 also rotates in the right direction in FIG. When the angle between the one link 46 and the other link 49 is substantially perpendicular, even if one link 46 rotates at a constant angular velocity, the other link 49 rotates slowly. When one link 46 and the other link 49 substantially coincide with each other, the other link 49 rotates at the highest speed. Furthermore, when it rotates and reaches a substantially right-angled position again, it rotates slowly, and when the drive-side rotation shaft 44 rotates 260 degrees, the driven-side rotation shaft 47 rotates 90 degrees, and the other link 49 rotates. It comes into contact with a stopper 52 and stops.
At this time, when one link 46 rotates 260 degrees,
Since the other link 49 rotates 90 degrees, the speed is reduced by 90/260.

Next, if the door 55 cannot be opened or closed automatically due to a power outage, motor failure, etc., when the door 55 is manually rotated, the driven side rotating shaft 47 will be connected to this via the hinge parts 40 and 41. An integral link 49 rotates. Then, the link 46 engaged with this link 49 and the drive-side rotating shaft 44 rotate, and further,
The motor 35 rotates via the reduction gear 43.

In the above embodiment, the guide roller 45 is provided on the link 46 and the guide groove 48 is provided on the link 49, but the guide groove 48 may be provided on the link 46 and the guide roller 45 may be provided on the link 49.

"Effects of the invention" (1) The drive part 35 is installed inside the gate post 34, and the hinge parts 40 and 41 are installed by fitting the gate post cylinder 37 and passing through the notches 38 and 39, and then attaching the door 55. In addition, when inspecting and repairing the drive part 35 inside the gate post 34, remove the hinge parts 40 and 41, remove the gate post cylinder 37, and then expose the drive part 35. Therefore, the installation and maintenance of the door 55 and the drive section 35 are easy.

(2) Since not only the drive device 35 but also the driven side rotating shaft 47 which is transmitted by the rotating shaft 44 of the drive device 35 is attached to the column 34a inside the gate post 34, no movable parts are exposed. , can be protected from rainwater and dust, and is highly safe.

(3) One end of the hinge parts 40, 41 is removably attached to the rotating shaft 47 side on the driven side through the hinge protrusion notches 38, 39, and the hinge parts 40, 4
Since the door 55 is attached to the protruding parts from the hinge protruding notches 38 and 39 of the gatepost cylinder 37 on the other end side of 1, various types of doors 55 can be attached by replacing the hinge parts 40 and 41. can be exchanged.

(4) The transmission mechanism between the rotating shaft 44 on the driving device 35 side and the rotating shaft 47 on the driven side is such that a link 46 with a guide roller 45 is connected to the rotating shaft 44, and
A link 49 having a guide groove 48 on the rotating shaft 47
are connected, and when the link 46 rotates, the guide roller 45 is engaged with the guide groove 48 and slides, and the link 49 is rotated, so that the opening and closing operation is slow at the beginning and end, and quick in the middle. It is safer for people passing by, and there is less chance of equipment failure.

(5) The transmission mechanism between the rotating shaft 44 on the driving device 35 side and the rotating shaft 47 on the driven side includes providing a fan-shaped recess 51 in the support base 50 in the gate post 34 to restrict the movement range of the link 49; By providing the recess 53 that restricts the movement range of the link 46, the rotation angle of the rotation shaft 44 and the rotation shaft 47, that is, the rotation angle of the door 55, becomes accurate, and not only does it not open or close more than necessary. In the case of a double door, when the door is closed, the two doors are always aligned, and no misalignment occurs.
