Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cone installed for dividing a predetermined area in a construction site, a traffic control area, or the like.

[0002]

2. Description of the Related Art A cone is used to clarify a danger area at a construction site such as a road repairing work or a civil engineering construction work and to guide a person.
It is used to regulate the traffic of vehicles in traffic-controlled areas and plays an important role in ensuring safety and preventing accidents. For this reason, it is required that the cones, including the bars, ropes, chains, etc., which are locked to the cones, be securely fixed, and the location and arrangement of the cones change frequently during use, making them easy to carry. It is important that the distance between the cones and the direction of the cones be easily changed. Conventionally, variously improved cones have been proposed in this regard.

For example, in Japanese Utility Model Registration No. 3048692, a vertical or horizontal bar is provided at the suspension ring portion of a cone bar passing through a circular center, and a concave portion for inserting the suspension ring is provided at the head of the cone. There is disclosed a cone in which a suspension ring is strongly pressed and inserted. According to this cone, the cone bar attached to the cone is hard to come off,
Installation is easy.

Further, Japanese Utility Model Registration No. 3029794 discloses a cone in which a rubber sheet for preventing slipping is attached to an upper end portion. According to this cone, when removing the stacked cones or retrieving the arranged cones, there is no missing or falling off, and the gripping force is reduced.

Japanese Utility Model Application Laid-Open No. 5-87014 discloses a cone provided with a tape connected to a winding device and configured to be able to be pulled out and a mounting member configured to lock a leading end of an adjacent tape. Has been described. According to this cone, the installation distance between the cones can be freely set, and the movement and resetting of the section range can be dealt with without delay, and it is possible to contribute to labor saving and space saving in cleaning up and transporting and storing.

[0006]

As described above, there have been proposed cones in which the fixing of the cones is ensured, the interval and the direction are easily changed, and the cones are easily transported. There are still points to be improved. The cone described in Japanese Utility Model Registration No. 3048692 discloses that the cone bar is securely fixed, but it is difficult to hold the cone by hand as in the case of a conventional cone.
There is a disadvantage that it cannot be carried with one hand.

The cone described in Japanese Utility Model Registration No. 3029794 has an anti-slip effect when grasped by hand, but requires a considerable gripping force to grasp and lift the cone, and moves a large number of cones. The problem of significantly fatigued hands and arms when carrying or carrying is not solved. The cone described in Japanese Utility Model Application Laid-Open No. 5-87014 has the advantage that the installation distance between the cones can be freely set, but it is difficult to hold the cone with one hand as with a conventional cone, and one-handed. It has the drawback of not being portable.

[0008] In addition to the above, there has been proposed a device in which a locking portion for locking a rope or a chain is provided at the upper end of a cone to securely fix the rope or chain (Japanese Utility Model Laid-Open No. 7-12513). However, such a structure,
When a cone bar with a suspension ring is used, there is a problem that the locking portion is in the way and it is difficult to fit the suspension ring.

The problem to be solved by the present invention is to make the cone easy to hold by hand when installing, clearing, transporting, and storing the cone, thereby saving labor for carrying work and ensuring the installation work.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a cone which is provided to divide a predetermined area at a construction site, a traffic control area, or the like, and has one or a plurality of through holes formed in an upper peripheral wall of the cone body. And a reinforcing material is attached to the periphery of the through hole. Here, it is preferable that the size of the through-hole is such that a finger can be inserted when the cone is carried.

By forming a through hole through which a finger can be inserted in the upper portion of the cone body, when carrying the cone, the finger can be inserted into this through hole and lifted up, so that the cone can be easily carried with one hand. The conventional method of gripping the top like a cone requires a great deal of gripping force to grip and lift, while the method of lifting with a finger can lift with little force. Also,
It is easy to change the direction and position of the cone while lifting it with your finger, and the direction of the cone is determined when you lift it with your finger. It can be easily installed according to the position and orientation.

Since the reinforcing material is attached to the periphery of the through hole, the attachment of the reinforcing material can prevent the periphery of the through hole from being chipped or broken. As the reinforcing material, a material having the same material as the cone body or having a strength equal to or higher than that of the cone body is used. As the material of the cone body, relatively soft synthetic rubber or hard synthetic resin is generally used, but when the cone body is made of synthetic rubber, synthetic rubber, synthetic resin, metal, etc. are used as reinforcing materials for the through holes. When a member is used and the cone body is made of synthetic resin, a member such as synthetic resin or metal can be used as a reinforcing material.

The reinforcing member can be attached to the peripheral edge of the through hole by means of, for example, screwing, bonding using an adhesive, fitting, or engaging with a claw. it can. Further, the reinforcing member may be composed of a pair of members, and may be attached from inside and outside of the cone.

When a hard synthetic resin or metal is used as the reinforcing material, the member is processed so that there is no sharp portion on the surface of the member so as not to hurt the finger inserted into the through hole.
On the other hand, if the cone is lifted if the entire surface is smooth, the finger will slip easily, so to prevent slipping, form an uneven surface on the surface that does not hurt the finger, or cover it with a soft material such as rubber. It is desirable to do.

The through hole in the upper part of the cone body not only allows a finger to be carried when carrying, but also allows a rope, a chain, a bar, etc. to pass through the hole. You can change the position of the cone or adjust the spacing as it is. In addition, a light-emitting body provided with a battery, a reflector that reflects light, an audio alarm with a sensor, a display board, and the like can be attached using a through hole.
