Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic opening/closing gate provided at the entrance of a parking lot or a house.

[Conventional technology]

Conventionally, fence-like automatic opening/closing gates installed at parking lot entrances, house entrances, especially apartment complex entrances, etc., have been constructed by laying two rails a horizontally on the ground, with running wheels attached to the lower end, as shown in Figure 7. Side view L
Place the plate-shaped gate body b of the mold on the rail a,
The gate body b is driven forward and backward by a cable in conjunction with a motor or the like, or by a rack and pinion system.

[Problem that the invention attempts to solve]

However, in the case of these automatic opening/closing gate bodies b that are L-shaped in side view, as a result of using two rails a, it is necessary to set the width of the lower part of the gate body b wide, and it is necessary to level the rail a itself. If the leveling is not done accurately, there is a problem that the wheels will wear out on one side, and even if the leveling is done accurately, the load applied to the wheels will be lower than that of the wheels located directly below the fence-like gate body b. Furthermore, the cable that drives the gate body b stretches over a long period of use, causing problems with the tension adjustment system, and because two rails a are used, space is required. The problem is that it requires a large area. The present invention is provided to solve these problems in automatic opening/closing gates.

In addition, as a conventional automatic opening/closing gate, it was actually opened in the 1980s.
There are also types such as No. 23598. This is an improved drive mechanism of the technology introduced in the conventional example described above. That is, instead of the rack and pinion method or cable traction method, a loop-shaped chain is used. Specifically, the chain is stretched in a loop shape between a pair of sprockets placed apart, and a motor is attached to one sprocket. The drive unit is constructed by associating the
The driving unit is arranged at the bottom of a wall fixedly installed on the ground, and the gate body is connected to the gate body by a connecting member protruding from a part of the chain, and the gate is rotated by rotating the chain in the forward or reverse direction. It moves the main body forward and backward.

However, automatic opening/closing gates employing this type of drive mechanism also have various problems. In other words, loop-shaped chains are used by standing vertically in order to save installation space, but because the chain is long, it tends to loosen due to its own weight, and the chain can come off the sprocket. There are concerns. Furthermore, this technique requires work to attach the drive unit to a fence that is fixedly installed on the ground, which poses a problem in that it requires a lot of labor and time.

The present invention aims to provide an automatic opening/closing gate that can solve these problems, and provides an automatic opening/closing gate that has less chain slack, can completely prevent the chain from falling off from the sprocket, and is easy to install. This is what I am trying to do.

[Means to solve the problem]

In order to solve this problem, the present inventor conducted extensive research and found that when arranging a chain, if the chain axis rod is vertical and the link plate is horizontal, the rigidity of the overlapping part of the link plate can be improved. They discovered that it is possible to prevent the chain from loosening, and also created a structure in which one chain is arranged in a straight line instead of arranging them in a loop, and also developed a sprocket that meshes with this chain to feed the chain. The present invention was completed based on the discovery that construction would be easier if the gate body was integrated into the guide means that maintains the upright state.

The automatic opening/closing gate of the present invention that solves such problems has a substantially plate-like structure that includes a rail arranged on the ground; wheels that roll on the rail are provided at the bottom, and a guided portion is provided in the length direction of the gate body. a gate body; a guide means provided on the side of the gate body and fixed to the ground, and provided with a guide portion for guiding the guided portion; Along the guide means, a single chain is placed flat so that the chain shaft rod is vertical and the link plate is horizontal, and is stretched in a straight line with both ends fixed to the gate body. A drive means that engages a drive sprocket associated with a drive source mounted in the guide means through a guide sprocket mounted thereon, and sends out the chain in the engaged state by rotation of the drive sprocket. It is characterized by having the following.

[Effect]

The automatic opening/closing gate of the present invention has a guide part installed in the guide means installed on the side of the gate body, which maintains the gate body in an upright state and allows a part of a chain stretched flat on the gate body to The gate body is moved forward and backward by engaging a driving sprocket through a guiding sprocket mounted in the guiding means and rotating the driving sprocket to send out the chain.

Since the guide part provided on the guide means installed on the side of the gate body guides the guided part of the gate body, one plate-shaped gate body can be stably erected, and a single rail can be used. It is possible to use a thin gate body, which does not require a large space for installation. In addition, a single chain arranged in a straight line is used, and the chain itself is placed flat so that the chain shaft is vertical and the link plate is horizontal, and the chain is horizontally pivoted as a guide. Since the chain is fed out by being engaged with the drive sprocket and the drive sprocket, the chain maintains its shape due to the rigidity of the overlapping portions of the link plates, and the chain does not loosen. Therefore, problems such as those caused by the chain falling off the sprocket never occur, and no maintenance is required over a long period of time.

Furthermore, the guiding sprocket and the driving sprocket for sending out the chain are mounted in a guiding means in which a guiding part is formed for guiding the gate body, and the drive-related mechanism other than the chain and the gate body are placed in an upright position. The automatic opening/closing gate can be easily constructed by simply transporting and installing the guide means with the drive-related mechanism integrated into the construction site, reducing the time and effort required for construction. and time can be significantly reduced.
