Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a barricade that is installed on a road or at a construction site to prevent entry into dangerous areas.

<Conventional technology and problems> Conventional barricades connect the supporting legs on both sides with an upper horizontal rod and a lower horizontal rod, and provide one leg body.
The supporting legs on both sides are connected by a lower horizontal rod to provide the other leg, and the upper ends of the other supporting legs are pivoted to the upper horizontal rod of one of the legs so that the legs can be opened and closed. It is constructed by attaching a foldable leg-spreading prevention rod consisting of two plates that regulates the leg-spreading angle between the lower horizontal rods of the body.

However, when using the legs apart, bend the body and
Until the folded spread restraint rod extends in a straight line,
Both legs can be opened by hand, and the legs can be closed during storage or transportation by bending the body and folding the legs to prevent the legs from opening by hand.
I was walking with my legs closed.

In this way, the opening/closing operation of the legs requires bending down and manually operating the leg-spreading restraining rod, which has the disadvantage of requiring a lot of effort to open/close the legs.

<Problems to be solved by the invention> The invention addresses the above-mentioned difficulties, and its purpose is to rotate one leg by grasping its upper transverse rod when the legs are closed. When the legs are opened, the legs can be opened at a predetermined angle, and even if the legs are exposed to wind pressure during use, there is no risk of the legs closing even if the entire body is lifted as it is. The purpose of the present invention is to provide a barricade whose legs can be closed by rotating one of the legs.

<Means for solving the problem> In order to achieve the above object, the present invention connects the supporting legs on both sides with an upper horizontal rod and a lower horizontal rod to form one leg body, and also connects the supporting legs on both sides with are connected by a lower horizontal rod to form the other leg, a bracket is provided above both supporting legs of the one leg, and the other leg has a vertical hole bored in the upper part of both supporting legs. Insert the shaft into the above bracket and attach the legs so that they can be opened and closed.
The stopper pin attached to each of the above brackets,
The stopper pin is inserted into a stopper hole consisting of a vertically long recess and a circular arc formed in the upper part of the support leg located on the bracket.The stopper pin is located in the circular arc of the stopper hole when the leg is closed, and in the vertically long recess of the stopper hole when the leg is opened. They are configured to engage with each other.

<Example> Examples will be described in detail below.

Reference numeral 1 designates one leg body, which is constructed by connecting supporting legs 2, 2 on both sides with an upper horizontal rod 3 and a lower horizontal rod 4. A frame-shaped bracket 5 having a U-shape in plan is attached to the upper part of the supporting legs 2, 2 on both sides. Reference numeral 6 denotes the other leg body, which is constructed by connecting support legs 7, 7 on both sides with a lower horizontal rod 8. The upper parts of the supporting legs 7, 7 on both sides are formed into a flat shape, and a vertically elongated hole 10 is bored in the flat part 9. The other leg 6 is constructed by inserting the upper flat parts 9 of the supporting legs 7, 7 into the bracket 5, and inserting the shaft 11 attached to the bracket 5 into the vertical hole 1.
0 and is attached to the bracket 5 so that the legs can be opened and closed. A stopper pin 12 is attached to each bracket 5, and is inserted into a stopper hole 15 formed of a vertically elongated recess 13 and an arcuate portion 14 formed in the upper part of the flat part 9 of the support legs 7,7. This stopper pin 12 is attached to a vertically elongated recess 13 of the stopper hole 15 when the legs are opened as shown in FIGS. 3 and 4.
1 and 2 to regulate the leg opening angle.
When the legs are closed as shown in the figure, they are removed from the vertically elongated recess 13 and positioned in the arcuate portion 14. Reference numeral 16 denotes a display board, which is suspended from the upper crossbar 3 of one of the legs 1.

1 and 2 show the barricade in a closed state where the barricade is lifted by gripping the upper horizontal rod 3 of one leg 1, and the other leg 6 is forced to close the stopper hole 15 by its weight. The shaft 11 is suspended by a stopper pin 12 located in the arc portion 14, and the shaft 11 is inserted into the vertical hole 10.
It is located at the bottom of the .

In this state, when using this barricade, when one leg 1 is rotated in the direction of arrow A from the lifted state, the stopper pin 12 moves the arcuate portion 14 in the stopper hole 15 from one end to the other end. At this point, the weight of the other leg body 6 acts on the other leg body, and the stopper pin 12 engages with the vertically long recess 13 of the stopper hole 15, and at the same time, the shaft 11 moves to the upper end of the vertically long hole 10 and the other leg body 6 moves. 6 descends,
The legs are opened in the state shown in Figure 4. When it touches the ground in this state, it can be installed with both supporting legs 1 and 6 spread out into an isosceles triangle as shown in FIG.
The opening angle of the legs is regulated by the engagement between the stopper pin 12 and the vertically elongated recess 13, and even if the legs are lifted, there is no danger of the legs being closed due to the engagement.

In the state shown in FIGS. 3 and 4, when the upper horizontal rod 3 of one leg 1 is grasped and pressed in the direction of the other leg 6, the stopper pin 12 comes out of the vertically elongated recess 13 of the stopper hole 15. arc part 14
At the same time, the shaft 11 moves to the lower end of the vertically elongated hole 10. In this state, when one leg 1 is rotated in the direction B and the barricade is lifted, the stopper pin 12 moves into the arcuate portion 14 of the stopper hole 15. is moved to one end, both legs 1 and 6 are brought closer together, and the legs are closed as shown in FIGS. 1 and 2.

<Effects of the invention> As is clear from the description of the above embodiment, in the present invention, when one leg is rotated by gripping its upper transverse rod in the closed state, the other leg can be rotated. Since the body descends under its own weight and the stopper pin engages with the vertically elongated recess of the stopper hole, the legs can be opened at a predetermined angle, and there is no need to provide a leg-spreading prevention rod as in the conventional example. Also, in this way, when the legs are spread,
The stopper pin engages with the vertically elongated recess of the stopper hole, so even if wind pressure is applied during use after the legs are opened,
Even if you lift the whole thing as it is, there is no risk of the legs closing.

Furthermore, in the present invention, when one leg presses the other leg when the legs are open, the stopper pin comes out of the vertically elongated recess of the stopper hole, so when one leg is rotated, the legs can be closed. .

As described above, the barricade of the present invention allows the legs to be opened and closed extremely easily and quickly by grasping the upper horizontal rod of one leg while standing without bending down. It has practical effects such as a simple structure.
