Description

Folding male bollard {FOLDABLE ∩-TYPE BOLLARD}

The present invention relates to a U-shaped bollard, and more particularly, it is possible to fold or stand the body more easily and easily by forming a folding hole rotated 90 degrees while being subjected to a torsion spring tension between the pillar and the support tube formed at the bottom of the body. So that it's about a folding bollard.

Generally, U-shaped bollards are installed at entrances such as sidewalks and parks, and are used for restricting traffic of vehicles.

Meanwhile, as bicycle lanes are recently activated, U-shaped bollards are installed in lanes to distinguish and warn the bicycle lanes and driveways.

In order to distinguish the bicycle road and the driveway, conventionally, both pillars of the U-shaped bollard were fixed in the ground, and in this case, there was a problem that the sanitation agency had to clean the broom directly because it was impossible to operate the cleaning vehicle.

In order to solve the above-mentioned problem, the U-shaped bollard and the body for restricting the passage of the vehicle; A support tube for supporting both pillars of the body; It consists of chains connected between the body and the support tube to prevent separation, if necessary, the body inserted into the support tube is lifted up and then lowered and laid on its side, and is lifted up and inserted into the support tube.

However, since the U-shaped bollard is made of a heavy metal pipe to prevent breakage and the like, it is difficult for a person to lift or lay down and suffer from difficulties.

The present invention has been made to solve the above problems, the use of the U-shaped bollard installed to limit the passage of the vehicle or to separate the boundaries of the roadway easier and simpler, with less force in use The purpose is to provide convenience.

The foldable U-shaped bollard of the present invention forms a folding hole between the pillar and the support tube of the body to achieve the above object, so that the upper joint and the lower joint constituting the folding hole receive the tension by the torsion spring. Means were devised to allow the body to be folded or erect with tension.

The foldable U-shaped bollard of the present invention described above is easier and simpler to use the foldable torsion of the torsion spring, and has the effect of providing convenience for use to fold or stand the body with less force.

Hereinafter, the configuration of the folding U-shaped bollard of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a front view of the foldable U-shaped bollard of the present invention, Figure 2 is a side view of the folded body of the foldable U-shaped bollard of the present invention.

As shown in Figs. 1 and 2, the U-shaped bollard 1 of the present invention includes: a body 2 having a plurality of shock absorbing layers and ultra-high brightness reflectors; A support tube 4 buried in the ground; It is composed of a folding hole (5) formed between the pillar (3) and the support tube (4) of the body (2).

As shown in FIG. 3, the folding port 5 includes an upper joint 8a fixed to a lower end of the column 3 by a screwing method or the like; A lower joint 8a fixed to the upper end of the support tube 4 by a screwing method or the like; A torsion spring (9) mounted between the upper joint (8a) and the lower joint (8b) and connected to the shaft (14); The upper joint 8a is composed of a pin 7 having a chain 6 connected to one side to fix the position of the body 2 coupled to the pillar 3.

In addition, the upper joint (8a) constituting the folding hole (5), as shown in Figure 4a, 4b, the upper end is formed with a screw for fastening to the column 3, the lower end of the upper joint shaft end (10a) While protruding to one side, the shaft fitting hole 11a is drilled through the center of the shaft end 10a.

And one end of the lower end of the shaft end (10a) of the upper joint (8a) is formed so that it can be easily rotated when folding the body (2), the other end of the lower end of the shaft end (10a) to be perpendicular to the body When erected vertically so as not to fall further back, the shaft end (10a) is formed through the fixing holes (13a, 13b) positioned at the 0 and 270 degrees point to form the U-shaped bollard (1) When (2) is erected vertically, the pin (7) is fixed to the position fixing hole (13a), and when the body (2) is rotated by 90 degrees, the pin (7) is fixed to the position fixing hole (13b). ) To be fixed.

As shown in FIGS. 5A and 5B, the lower joint 8b constituting the folding hole 5 is provided with a screw for fastening to the support tube 4 at a lower end thereof, and a lower joint shaft end 10b thereon. The torsion spring mounting groove 15 is provided in the middle of the branched shaft end 10b.

A shaft joint hole 11b is formed at the center of the branched shaft end 10b of the lower joint 8b, and a pin hole 12 is formed above the shaft joint hole 11b.

Meanwhile, one wing 9a of the torsion spring 9, which is mounted by connecting the upper and lower joint shaft ends 10a and 10b of the upper joint 8a and the lower joint 8b and the shaft 14, is connected to the upper joint. It is fixed above the shaft end (10a), the other wing (9b) of the torsion spring (9) is fixed to the bottom of the torsion spring mounting groove (15) of the lower joint shaft end (10a) is subjected to tension during rotation.

The U-shaped bollard 1 of the present invention configured as described above is installed in the lane to distinguish the boundary between the bicycle road and the driveway, in which the hole is drilled in the lane and the support tube 4 is fixed firmly.

The U-shaped bollard (1) normally maintains the body (2) in the upright position to limit the traffic of the vehicle or to separate the road between the bicycle lane and the road, the body (2) when the traffic of the cleaning vehicle is required Fold 90 degrees.

At this time, provided in the folding hole (5) formed between the pillar (3) and the support tube (4) of the body (2), pull out the pin (7) connected to the chain (6) on one side and then remove the body (2) And the lower joint shaft end 10b of the lower joint 8b in which the upper joint shaft end 10a of the upper joint 8a constituting the folding hole 5 is connected to the shaft 14 by pulling down and pulling sideways. ) Is rotated by 90 degrees, and the torsion spring 9 mounted between the upper joint shaft end 10a and the lower joint shaft end 10b is subjected to tension.

As described above, after the body 2 is rotated by 90 degrees and folded, the pin 7 is formed in the upper joint 8a while being pushed into the pin hole 12 of the lower joint 8b. If it passes through 13b, it will be fixed.

On the contrary, when the body 2, which has been rotated by 90 degrees, is erected, the pin 7 that has been inserted into the position fixing hole 13b formed in the upper joint 8a of the folding hole 5 is removed, and then the body 2 is removed. When slightly lifted up, the body (2) is easily upright by the restoring force of the torsion spring (9), which is mounted between the upper and lower joints (8a) and (8b) under tension, and the pin (7) is fixed by inserting it into the pin hole 12 formed in the lower joint 8b so as to pass through the position fixing hole 13a formed in the upper joint 8a.
