DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic gate of the present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 denotes a gate pillar that is installed at the entrance of a parking lot or a house. Two gate pillars are arranged facing each other according to a predetermined width of the entrance, and a sprocket wheel 8 is provided at a vertical position in the gate pillar.・ 8 rotatably arranged and the upper and lower sprocket wheels 8 ・
The chain 6 is stretched between the eight. Then, any one of these, for example, an upper sprocket wheel is attached with a motor of the lifting device 7 to drive the chain.

Ends of the horizontal crossing members 2 having a required strength are locked to the chains 6 and 6 and auxiliary horizontal cross members 3 are formed at predetermined intervals from the horizontal horizontal members 2 for blocking. A plurality of 3 are provided, and the ends of the auxiliary horizontal member and the blocking horizontal member are slidably inserted and supported in the long holes formed along the longitudinal direction of the inner surface of the gate pillar. Then, the blocking horizontal member and the auxiliary horizontal member are connected to each other via the rope 4 such as a chain or a link.

[0009] A plurality of connecting cords for connecting the blocking horizontal member and the auxiliary horizontal member are arranged at required intervals in the longitudinal direction of the blocking horizontal member. The horizontal members should be supported so that they are almost parallel to each other. A lower horizontal member 9 is disposed below the lowermost step of the plurality of auxiliary horizontal members, and the lower horizontal members 9 are connected by the cords in the same manner as the auxiliary horizontal members.

Further, a horizontal crossing member for protection, an auxiliary horizontal crossing member, etc. are fitted and inserted on the floor surface between the gate posts, and a horizontal crossing member is fitted with an upper surface opened so that the horizontal crossing member for blocking is flush with the floor surface. A ply box 10 is provided. Therefore, the blocking horizontal member, the auxiliary horizontal member, and the lower horizontal member have a cross-sectional shape that fits inside the horizontal member fitting box. When the horizontal blocking member is housed in the fitting box, the opening surface of the fitting box is closed as shown in FIG.

Further, as shown in FIG. 4, the auxiliary horizontal members, which are interposed between the lower horizontal members and the blocking horizontal members, are fitted on the lower portions of the horizontal blocking members so as to overlap each other and are stored in a low volume. At the same time, the transmission shaft 5 is rotatably arranged at the bottom of the insertion box below the lower horizontal member, the sprocket wheels are supported at both ends of the transmission shaft, and the chains are meshed with each other.

Therefore, in the automatic gate formed as described above, when the gate is opened from the closed state as shown in FIG. 1, when the motor of the lifting device 7 is driven, the chain is driven via the sprocket wheel. As a result, the blocking horizontal member locked in the chain descends. At this time, the lower horizontal member suspended from the connecting cords is first stored in the fitting box, and then the lower horizontal member is sequentially folded and stored in the fitting box. The gate is completely opened by closing the opening surface of the fitting box with the horizontal crossing material.

On the other hand, when the opened gate is closed, the chain is driven in the opposite direction by rotating the motor in the opposite direction, and the blocking horizontal member is pulled up by the chain. . As the blocking horizontal member rises, the auxiliary horizontal member and the lower horizontal member connected to the connecting horizontal member are sequentially pulled up, and the gate is completely closed.

When the gate is opened and closed, the lifting device is turned on and off to drive the motor, and the motor is automatically stopped when the horizontal crossing member reaches a predetermined position. Provide a switch, etc.

In the above embodiment, the chain is used as the means for moving up and down the blocking horizontal member, but it is also possible to use a wire or the like.

[0016]

According to the automatic gate of the present invention, a plurality of blocking horizontal members and auxiliary horizontal members are connected to each other between the gate columns installed opposite to each other so as to be vertically movable and the blocking horizontal members. Since it is provided with an elevating means for elevating and lowering, and when the horizontal member is raised, it blocks the space between the opposite gate columns, and when it is lowered, it is depressed into the floor, the mechanism is simple and the operation can be surely performed. Also, when the gates are lowered, the space between the gateposts becomes completely flat, and the opening width between the gateposts can be maximized, and an automatic opening / closing gate with a large opening width can be used even on a site where there is little room in the lateral direction of the entrance. There are advantages such as being provided.
