Retractable vehicle barrier with anti-twist belt for pull-in wire

Abstract

To reduce the number of sagging prevention rings and prevent the rings from acting as resistance to the wire, taking into consideration the retracting speed and sagging of the wire when the wire of an opening prevention stopper device for a retractable vehicle blocking fence is retracted. [Solution] The wire of the retractable vehicle barrier opening prevention stopper device 1 is provided with a guide ring 2 for extending it from the vertical direction to the horizontal direction, and the number of rings is sufficient to compensate for the sagging of the wire even when it is closed quickly, and each of the rings is structured to pull the ring downward so as not to create resistance when the wire is retracted.

Description

[Technical field]

[0001] This invention relates to an extendable vehicle barrier equipped with a retractable wire twist prevention belt that prevents twisting of the wire when the wire is retracted by the opening prevention device of the retractable vehicle barrier. [Background technology]

[0002] In conventional retractable vehicle barrier opening prevention device devices, there are four rings to prevent the wire from sagging when the wire is retracted.When the wire is retracted, this creates resistance and causes the wire to twist, often rendering it ineffective as an opening prevention device.

[0003] General Catalog 2024 p57 J-Win Co., Ltd. Summary of the Invention [Problem to be solved by the invention]

[0004] In consideration of the above-mentioned conventional situation, this invention aims to reduce the number of sagging prevention rings, taking into account the wire retraction speed and wire sagging when the wire of the opening prevention stop device of a retractable vehicle barrier is retracted, so that the rings do not become a resistance to the wire. [Means for solving the problem]

[0005] In order to achieve the above-mentioned objective, this device provides a guide ring for extending the wire of a retractable vehicle barrier opening prevention device from a vertical direction to a horizontal direction, and a number of rings to compensate for the sagging of the wire even when the barrier is closed quickly, and each of these rings is designed to pull downward so as not to create resistance when the wire is retracted. Effect of the Invention

[0006] As is clear from the above description, the present invention has the following advantages: (1) By minimizing the retraction resistance of the wire of the retractable vehicle barrier opening prevention device, the function of the opening prevention device can be extended as long as possible.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. EXAMPLES

[0009] Fig. 1 is a front view of the vehicle blocking telescopic fence of the first embodiment of the device of the present invention, in which a pull-in wire twist prevention belt is attached from the wheel shaft to the middle pipe frame. Fig. 2 is a side view, and Fig. 3 is an open view from the arrow. Fig. 4 is an arrow view before the twist prevention measures were taken. There are four rings through which the pull-in wire passes, and the direction of the rings is not constant, facing sideways or upwards, which causes an obstacle when the wire is pulled in, causing the wire to twist or to hang down without being pulled in. This makes the opening stopper device useless. As a countermeasure, as shown in Fig. 3, there are two rings, a guide ring 2 and a sagging prevention ring 3, and a pull-in wire twist prevention belt is attached to the rings and the wheel shaft as shown in the figure, so that they always face the wheel direction, preventing the wire from twisting or sagging. [Industrial Applicability]

[0010] To provide an opening stopper device for a retractable vehicle barrier that can be used for a long period of time. [Explanation of symbols]

Claims

[Claim 1] An expandable vehicle barrier in which the ring through which the pull-in wire passes is always oriented in the direction of the wheels thanks to a twist-prevention belt.
