Description

  The present invention relates to a gate device for restricting traffic provided in an entrance / exit passage of a building or facility, and more specifically, raises and lowers a restricting member between a lowered position that prevents passage of the passage and an elevated position that does not prevent passage. The present invention relates to a gate device.

This type of gate device has been mainly used in which a regulating member is suspended from above with a wire, and the wire is lifted and lowered by winding the wire around a reel.
However, in order to raise and lower a firm heavy regulating member by the conventional method, a driving device such as a motor and a reduction gear for driving the reel is inevitably enlarged. Therefore, a correspondingly large space for installing these drive units is required above the passage, vibration and noise are large, and the winding speed is slow.
turn into.

  On the other hand, as a device that can move the restricting member up and down even when there is no space above the passage, for example, the other end of the main arm that is pivotally coupled to the gate body is pivotally coupled to the column. There has been proposed a gate opening and closing device in which the other end of the auxiliary arm is connected to a support column so as to be rotatable and vertically movable (see, for example, Patent Document 1).

  However, such a device that rotates with an arm requires a rotation width in the front-rear direction, and when a heavy weight regulating member is moved up and down, a large load is applied to the arm and the drive unit, and there is a limit.

  Therefore, there is a problem that the space above the passage is limited and quietness is also required. For example, in an underground parking lot of an apartment house, there is a problem that an elevating gate for raising and lowering a heavy regulating member cannot be installed.

It is a fence body composed of ... The lengths, intervals, and the like of the horizontal rods 20 and 21 and the vertical rods 22 of these fence bodies are appropriately set according to the width and height of the passage W, the number of the fence bodies, and the like. In addition, structures other than such a fence body are also employable.

  The lower split member 2A is provided with a locking piece 23 that is engaged with the split member 2B and integrated with each other at a position that rises and overlaps the upper split member 2B. In this example, the regulating member 2 is configured in two stages, but in the case of three or more stages, the lowermost divided member may be provided with a locking piece that engages with another divided member, or Each division member may be provided with a locking piece that engages with the division member adjacent on the upper side.

  The left and right guide members 3 are formed by juxtaposing a plurality of guide rails 3A and 3B that hold the left and right end portions of the respective divided members 2A and 2B and guide them up and down while regulating lateral blurring. Sliding members 24, 24 that slide on the inner surface of the guide rail are provided on the vertical rods at the left and right end portions of the guide rail.

The guide rails 3A and 3B are provided with latching portions 30A and 30B for holding the divided members 2A and 2B at their predetermined lowered positions. However, the latching portion 30A that supports the split member 2A may be omitted.
