Description

  The present invention relates to a gate bar device that is opened and closed by a gate opening / closing device installed in an entrance lane, an exit lane, or the like of a parking lot, and more specifically, a foldable gate bar in which the gate bar is configured to be foldable. It relates to the device.

  As for the folding gate bar device used in a parking lot, there is a “rotating device for a folding gate bar” described in Patent Document 1 conventionally.

  FIG. 12 illustrates the configuration of a “turning device for a half-folded gate bar” described in Patent Document 1 as a conventional example. In FIG. 12, 101 is a gate opening / closing device, 110 is a opening / closing device for a root end portion. 101, a proximal-side bar attached to the rotary shaft 102, and 120, a distal-side bar that is pivotally supported by the distal end side of the proximal-side bar 110 so as to be able to be bent using joint joint means generally indicated by reference numeral 103. The proximal bar 110 and the distal end bar 120 constitute a gate bar. Further, 131 is a pivot lever whose lower end is pivotally supported at the tip of the proximal bar 110 and whose upper end protrudes obliquely upward in the direction of the switch 101 when the proximal bar 110 is horizontal. Thus, a pulling member 140 is attached between the upper end of the rotating lever 131 and the opening / closing machine 101, and the opening / closing operation is performed while the front end side bar 120 is always kept in a horizontal state.

Reference numeral 132 denotes an intermediate lever having one end pivotally supported on the upper end portion side of the pivot lever 131 and the other end pivotally supported on the root end portion of the distal end side bar 120. As shown in the figure, the front end bar 120 is opened and closed in a folded state while maintaining the horizontal state by the link means constituted by the intermediate lever 132 and the pulling member 140 according to the opening and closing operation of the hand side bar 101. It is configured.
Japanese Patent No. 3162935

  However, the “turning device for a half-folded gate bar” described in the above-mentioned Patent Document 1 is an upper side constituting the joint interlocking means (four-node parallel link means) generally indicated by reference numeral 130 as shown in FIG. An intermediate portion of the rotation lever 131 protrudes from the upper side surface of the distal end portion of the proximal side bar 110. In addition, the rotational support shaft of the proximal side bar 110 and the distal end side bar 120 is biased toward the lower portion of the gate bar. In addition, since each part has a complicated shape, several gaps are created during the opening and closing operation of the gate bar, resulting in a large space. There was a risk of catching hands.

  Furthermore, since the device described in Patent Document 1 has a lot of irregularities in the middle bent portion, even if the entire gate bar is covered with a cover in order to protect vehicles, passers-by, etc., the periphery of the bent portion is covered. In particular, since the lower protrusion cannot be covered with a simple cover or the like to ensure safety, a cover with a complicated shape is required, which increases the cost.

  Therefore, the technical problem of the present invention is to reduce the number of protrusions around the intermediate portion that is bent halfway, and to prevent a space portion that may pinch a hand when the gate bar is opened and closed, so An object of the present invention is to provide a folding gate bar device that is devised so that it can be used safely for people.
