Abstract

PURPOSE:To provide horizontal bar supporting legs for a barricade by which a fence can be installed in the very limit of a restricted area. CONSTITUTION:This horizontal bar supporting legs are constituted of a pair of legs 1a, 1b of which one-side ends are rotatably supported capably of being opened/closed, and a pair of leg connecting tools 4a, 4b of which one-side ends are rotationally movably supported with the pair of legs and the other ends are connected together capably of being bent mutually and oppositely. One 1a of the pair of legs is nearly vertical against the installing face at opening the legs, and horizontal bars 10, 11 or 10, 12 are respectively pinchedly held with the rotatable supporting part of the pair of legs and the positions between the connecting tools and at least the one leg.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal bar support leg for barricades used in the field of construction work, road works and the like.

[0002]

2. Description of the Related Art Barricades are used to clearly indicate prohibited areas during road construction. Since such a barricade must be movable as required, it is required that it can be freely assembled and disassembled for ease of transportation. Also, since construction work and road works are usually performed over a wide area, it is absolutely necessary that the barricade price be low.

For example, a barricade which has been conventionally used in road construction or the like, as described in Japanese Utility Model Publication No. 62-7687 of the present applicant, holds a pipe between two A-type supporting legs to form a barricade. I was making up. Then, a fence was installed between the two pipes to prohibit traffic, but this fence got into the center of the A type, and it was a restricted area (according to the conventional barricade, two pipes were supported. There was a drawback that the fence could not be installed at the last minute.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a fence supported by a pipe supported by A-type supporting legs is installed at the end of a barricade, and is restricted to a restricted area. It is an object of the present invention to provide a horizontal bar support leg for a barricade in which a fence is installed.

[0005]

In order to achieve the above-mentioned object, the present invention pivotally supports one end of a pair of legs so as to be openable and closable with respect to each other, and the opening and closing is performed by bending a leg connecting tool provided on the leg. It is characterized in that it is configured such that a connecting horizontal bar can be held between the shaft supporting portions of the pair of legs and the leg connecting tool and the leg.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings. In FIGS. 1, 2 and 3, grippers 2a and 2b are fixed to the tips of the legs 1a and 1b, respectively. The grippers 2a and 2b are, for example, a shaft 3 composed of a bolt and a nut and a gripper 2a. 2b and legs 1a, 1b are pivotally supported so that they can be opened and closed. The legs 1a are made of a substantially straight channel material, and the legs 1b are made of a channel material which is bent in a V shape at about 1/3. When the legs are opened, the other ends of the legs 1a and 1b with respect to the grippers 2a and 2b are substantially parallel to each other and perpendicular to the installation surface.

Leg connecting tools 4a and 4b are attached near the other ends of the gripping tools 2a and 2b of the legs 1a and 1b. As shown in FIG. 3, in order to make the legs 1a and 1b foldable,
The leg connector 4b is longer than the leg connector 4b.
One ends of the leg connecting tools 4a, 4b are rotatably supported by the legs 1a, 1b via shafts 5a, 5b composed of bolts and nuts, and the other ends thereof are supported by a shaft 6 also composed of bolts and nuts. The leg connectors 4a and 4b are connected to each other and the shaft 6
The legs 1a and 1b can be bent with the legs opened and closed. The leg connecting tools 4a, 4b are attached to the legs 1a,
It is preferably mounted at a position 1/3 to 1/4 below the length of 1b.

Next, the operation of the above-mentioned barricade horizontal bar support leg will be described. The legs 1a and 1b are opened and closed around the shaft 3, and accordingly, the grasping tools 2a and 2b and the leg connecting tools 4a and 4 are provided.
The tip of b is also bent in the direction of the grippers 2a and 2b. Leg 1
The leg connectors 4a and 4b are aligned with each other when a and 1b are opened. Collars 7a, 7b project near the shafts 5a, 5b of the legs 1a, 1b so that the horizontal bar can be sandwiched between the leg connectors 4a, 4b and the legs 1a, 1b.

Next, a method of using the barricade horizontal bar support leg described above with reference to FIG. 4 will be described. The horizontal bar 10 is placed in the space formed by the grippers 2a, 2b and the horizontal bar 11 is placed in the space formed by the grippers 6, 6'with the legs 1a, 1b being half opened (FIG. 3). . Furthermore, the leg connector 4
The horizontal bars 11 and 12 are placed in the spaces formed between a and 4b, the legs 1a and 1b, and the collars 7a and 7b, respectively.

Next, when the legs 1a and 1b are completely opened, the grasping tools 2a and 2b and the leg connecting tools 4a and 4b are operated according to the principle of leverage.
, The legs 1a, 1b, and the collars 7a, 7b completely hold the horizontal bars 10, 11, 12 respectively, and the horizontal bars 10, 11, 1
2 does not move laterally. A protective net 13 for preventing children from entering can be installed between the horizontal bars 10 and 11.
Further, by using the horizontal bar 11 that is thinner (lighter) than the horizontal bar 12, the barricade can be made less likely to fall over the entire surface.

Usually, this type of support leg is provided with a leg 1a by its own weight,
1b acts freely and the horizontal bars 10, 11, 12 naturally act as the grippers 2a, 2b and the leg connectors 4a, 4b, and the leg 1.
The horizontal bar 1 is held between a and 1b and the brims 7a and 7b.
There is no need to attach a special means for fixing 0, 11, 12 to the legs 1a, 1b, the appearance is neat, and there are no protrusions, which is convenient for transportation. In addition, barricades can be installed at the last minute of the safety area. It should be noted that the reference numbers recited in the claims should not be construed as limiting the claims for the purpose of easy understanding of the invention.

[0012]

As described above, according to the present invention, there is provided a horizontal bar supporting leg for a barricade which has an extremely simple structure, is inexpensive, can be easily assembled, disassembled, and transported, and can be installed at the end of a safe area. You can
