It is a feature.

The tape type security fence of the present invention will be described in detail. The case is a member that accommodates a tape, that is, a regulation tape, and is also a main body of the tape type security fence.
The case is made of a resin material formed in a desired shape, and a rotating body (for example, a drum body) around which a restriction tape is wound is supported on a shaft standing in the case. Has been.

  Also, the case is usually molded using a resin material with excellent moldability, but it can be formed using other materials such as a metal material, or a synthetic resin for shock buffering, etc. An elastic member may be provided.

  Inside the rotating body, a coiled winding spring (spring spring) for automatically winding the tape connected to the rotating body is provided, so that the rotating body is arranged around the axis mentioned above. The tape is always urged in the direction in the case, that is, the winding direction.

The tape enters and exits from the tape entrance / exit provided in the case, and when the winding of the tape is finished, the mounting member connected to the tape leading end is locked to the tape entrance / exit (the tape enters the case). Will be prevented from being pulled in).
In addition, it is desirable from the viewpoint of tape protection that the mounting member is locked to the tape inlet / outlet portion so that a part or the whole of the connecting portion of the mounting member is positioned in a substantially fitted state in the tape inlet / outlet port.

  Therefore, the connecting portion of the mounting member is composed of a pin having a trident in the longitudinal direction and a pin accommodating portion in which the pin can be inserted from the tip end of the trident, and the center of the trifurcated portion of the pin accommodated in the pin accommodating portion. A slit having a predetermined length (dimension) is formed at a portion facing the pin.

  The slit has a cylindrical portion provided in the width direction of the end portion of the tape so that the tape can pass through at least a dimension (slit length) when the pin fitted to the center pin of the three-pronged portion of the pin is inserted.

  Further, the thickness of the central pin in the trifurcated portion of the pin is such that at least the cylindrical portion provided in the width direction of the tape end portion is fitted, the gap (slit) between the right pin and the central pin in the trifurcated portion of the pin, the left side The gap (slit) dimension between the pin and the center pin is selected in consideration of at least the thickness of the tape.

And the center pin of the pin that fits the cylindrical part at the tip of the tape is the outside of the slit due to the tension of the tape that is stretched between the external members (safety devices) when using the tape-type security fence. When the pin is inserted and set in the pin housing part, at least the tip of the central pin of the pin should be positioned inward of the pin housing part beyond the tip part of the slit. desirable.

The tape may automatically stop (lock) at the specified position.

  Also, when returning the tape into the case, both the former and the latter should be able to release the tape (lock) by operating the operating means such as buttons and levers so that the tape can be wound into the case. do it.

  In addition, the mounting member is a ring when the external member (security device) for mounting the mounting member is a load cone, but when the external member (security device) is in another shape, The shape is adapted to the shape of the external member (security device), and the shape is not particularly limited.

And, on the opposite side of the case from the tape entrance, there is provided a main body mounting member for mounting the case as the main body of the tape-type security fence to an external member (security device), and the main body mounting member is provided at the tip of the tape. For example, if the mounting member provided at the front end of the tape is a ring body, the main body mounting member is also a ring body.
However, the mounting member at the front end of the tape may be different from the main body mounting member.

  In addition, when the main body mounting member is configured to be detachable from the case and the mounting member at the tip of the tape is changed to another type, the main body mounting member may be replaced in accordance with the replaced mounting member. Sometimes it can be done.

  The material of the case and the mounting member is not particularly limited, and may be formed using, for example, a synthetic resin material (including rubber) that can be easily molded. Of course, you may form using a metal material, a carbon material, etc.

In addition to the three-pronged pin most suitable for the present invention, two or four or more pins may be used depending on the size of the tape-type security fence, the tape length, and the like.
In this case, a slit is provided at a site substantially opposite to the fitting pin for fitting the cylindrical portion provided at the tip of the tape set (accommodated) in the pin accommodating portion.

  According to the tape-type security fence of the present invention, since the connection between the tape and the mounting member for mounting on the mounted security device can be easily released, the above-mentioned mounting is performed while using the tape-type security fence. Even when the mounting member is damaged and the mounting member must be replaced on site, the connection between the tape and the mounting member can be released and the replaced mounting member and the tape can be connected in a short time.

  As a result, it is possible to shorten the time at which the tape on the site, that is, the restriction line is released, so that the occurrence rate of the disaster caused by the release of the restriction line can be extremely low, and the mounting member Since the replacement work can be performed in a short time, the burden on the replacement worker can be greatly reduced. In addition, the replacement can be simplified and the connection of the replaced mounting member and the tape can be easily and firmly connected. Secondary disasters can be prevented.
