[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a car stop strut that is installed upright along the sidewalk to separate an entrance / exit of a park or a sidewalk from a sidewalk, and a horizontal pipe for connecting a lateral pipe passed between the strut. Regarding the coupling device.

[0002]

[Prior art]

 At the entrances and exits of parks and at the boundaries between roads and sidewalks, car stop stanchions are erected for the purpose of restricting the passage of vehicles and people, and further, intrusion prevention to prevent traffic between the stanchions. A horizontal pipe is passed over.

In the conventional connecting means for the horizontal pipe, a fitting hole is formed in advance on a required side surface of the car stop strut, and the lateral pipe is made a little longer than the interval between the strut so that a few pipes are formed. The pillars were assembled as a set, and the horizontal pipes were previously connected and connected, and this was raised, and the work of standing up each pillar was repeated to perform the construction.

The means for preliminarily fixing the lateral pipe requires a plurality of workers because it is long in the lateral direction and has a large load. Further, the lateral pipe may come off during the work, or The work was not efficient because it was restrained by the horizontal pipes and the work of burying the columns did not proceed. In this case, the columns and the horizontal pipes may be assembled one by one, but it is more inefficient and time-consuming to sequentially perform different steps including the concrete driving work, and in the end, the above-mentioned work I have to rely on you. In addition, no matter what steps were taken, the horizontal pipe would be completely fixed after the construction, so even if the horizontal pipe were damaged, it was not easy to replace it.

In view of this, there is provided a vehicle stop strut having a short receiving pipe screwed to the vehicle stop strut and a lateral pipe between the adjacent vehicle stop strut that is connected at both ends to the receiving pipe afterwards by a connecting means. A lateral pipe connecting device has been proposed.

In this structure, the receiving pipe is fixed in advance to the car stop strut body, and then the lateral pipe is connected between the adjacent car stop strut by connecting the both ends to the receiving pipe by means of connecting means. Yes, it is possible to fix the car stop strut body first by retrofitting the horizontal pipe, which facilitates the installation work and allows one operator to do the work. It has the advantage that it can be easily replaced.

[0007]

[Problems to be solved by the device]

 Generally, in order to stand a car stop strut on a road surface with a slope, it is not a right angle to the slope but a right angle (that is, a vertical direction) to the horizontal plane. In such a case, the horizontal pipe is fixed at almost the same position of the car stop strut, so if the horizontal pipe is to be applied, it will be slanted due to the drop between the strut. It was not possible to deal with it in the configuration. Therefore, in such a case, a chain was used instead of the horizontal pipe to cope with the situation.

It is an object of the present invention to provide a lateral pipe connecting device for a bollard strut having a structure capable of coping with a sloped road surface.

[0009]

[Means for Solving the Problems]

 According to the present invention, a fixed metal fitting is fixed to a side surface of a car stop column, and an outer surface is formed with a vertical arcuate guide surface, and an end face is formed with an arcuate sliding surface in close contact with the fixed metal fitting. Adjacent to the arcuate guide surface, the arcuate sliding surface is abutted, and the guide action of both arcuate surfaces allows it to tilt up and down, which is screwed to the car stop column through the fixing metal fittings. It is characterized in that it is provided with lateral pipes between the vehicle stop struts, the both ends of which are connected to the receiving pipe by a connecting means afterwards.

Here, the vertical arcuate guide surface and the arcuate sliding surface include spherical surfaces. When one is a convex surface, the other closely contacting this is a concave surface.

[0011]

[Action]

 The receiving pipe is screwed to the car stop column through the fixing bracket. At this time, the receiving pipe and the fixing bracket are in intimate surface contact with each other on the arc-shaped guide surface and the arc-shaped sliding surface, and the guiding action causes the receiving pipe to move to an arbitrary position with respect to the fixing bracket. It can be tilted in the vertical direction, and its tilted position is maintained with the screwing operation. And this inclination angle is made to correspond to the inclination of the road surface on which the car stop columns are erected. Then, the lateral pipe is attached between the adjacent car stop struts by retrofitting the both ends to the receiving pipe by the connecting means.

【Example】

 An embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 4, the car stop strut 1 is provided with a strut body 2, a head 3 fixed to the upper end of the strut body 2, and a plurality of rod-shaped anchors 4 projecting from the strut body 2. It comprises a cylindrical driving member 5 which is connected to a male screw formed at the lower end of the column main body 2 and is buried in the ground.

A screw hole 11 penetrating inward is formed in the center of the opposing peripheral surface of the pillar main body 2.

At the position of the screw hole 11, a short tubular receiving pipe 15 is fixed via a fixing fitting 12. A through hole 13 is formed in the center of the fixing fitting 12, and a convex arcuate guide surface 14 is formed on the outer surface thereof.

The receiving pipe 15 has a bottomed shape, one end of which is shielded by an end plate portion 16. The end plate portion 16 has an arc shape, and the outer surface thereof is a concave arc sliding surface 18 having the same curvature as the arc guide surface 14. An elongated hole 17 is formed in the end plate portion 16 of the receiving pipe 15 in the upward and downward directions. Further, a through hole 19 is formed on the peripheral surface of the receiving pipe 15.

Further, in the receiving pipe 15, an arcuate surface having the same curvature as that of the end plate portion 16 is formed on the inner surface of the receiving pipe 15 so as to abut the end plate portion 16, and the outer surface is a flat bolt supporting surface and the center is A fixed washer 20 having a through hole 21 formed therein is disposed. The fixed washer 20 has a diameter smaller than the inner diameter of the receiving pipe 15 and is relatively movable along the inner surface of the arc of the end plate portion 16. Then, in the receiving pipe 15, a fixing bolt 23 is inserted from the through hole 21 through the long hole 17 of the end plate portion 16 and the through hole 13 of the fixing metal fitting 12, and the head thereof is attached to the outer surface of the fixed washer 20. Is supported by.

In such a structure, the arcuate guide surface 14 and the arcuate sliding surface 18 are formed by arcuate surfaces curved only in the up-down direction or spherical surfaces. By the surface contact between the arcuate guide surface 14 and the arcuate sliding surface 18, the receiving pipe 15 can be tilted and adjusted in the up-down direction along the arcuate guide surface 14 with the arc center as the center of rotation. As will be described later, it is appropriately tilted in accordance with the tilt angle of the road surface f, and the tilted position is held by the fixing bolt 23. The horizontal pipe 25 provided between the pillar bodies 2 is a circular pipe having the same outer diameter and the same material as the receiving pipe 15. Then, at both ends thereof, long holes 26, 26 are formed along the longitudinal direction.

Further, at both ends of the horizontal pipe 25, a short pipe having an inner diameter which is fitted into the horizontal pipe 25 constituting the connecting means in a substantially close contact manner and having screw holes 31 and 32 formed at both ends thereof. The inner pipe 30 is fitted.

Next, the connecting means of the horizontal pipe 25 will be described.

In such a configuration, as shown in FIG. 4, when applied to a road surface f with a slope, first, the car stop columns 1 are fixed in advance at a predetermined interval in a direction perpendicular to the horizontal plane. In this state, a drop is generated on each of the car stop support columns 1 corresponding to the inclination of the road surface f. Therefore, the fixing bolts 23 are loosened to incline the receiving pipe 15 so as to be parallel to the road surface f, as shown in FIG. 3, so that the receiving pipes 15 and 15 of the adjacent car stop columns 1 and 1 are placed on the road surface f. So that they face each other. At this time, the end plate portion 16 of the receiving pipe 15 is loosely clamped between the fixing metal fitting 12 and the fixed washer 20 as shown in FIG. 2, and the circular arc guide surface 14 and the circular arc sliding surface 18 cause the arc center to move. With the long hole 17 as the center of rotation, the rotation thereof is allowed to allow tilting. After fixing the position, the fixing bolt 23 is tightened again.

On the other hand, the long holes 26, 26 (only one of which is shown) formed at both ends of the horizontal pipe 25 are communicated with the screw holes 31 of the short inner pipe 30 fitted in the horizontal pipe 25 in advance. Then, the position of the inner pipe 30 is adjusted, and the screw 33 is screwed to the extent that the inner pipe 30 can slide from the elongated hole 26 to the screw hole 31.

Next, the inner pipe 30 is completely inserted into the horizontal pipe 25, the horizontal pipe 25 is brought into contact with the receiving pipe 15 at their end edges, and the screw 33 is operated by a finger to move along the long hole 26. And slide it to insert the end of the inner pipe 30 into the receiving pipe 15. Then, another screw hole 32 formed in the inner pipe 30 is communicated with the through hole 19 of the receiving pipe 15, and the screw 34 is screwed from the through hole 19 into the screw hole 32. When the screws 33 and 34 are tightened, the horizontal pipe 25 is connected between the pillar bodies 2 and 2.

Therefore, even if the road surface f has a slope as shown in FIG. 4, the horizontal pipe 25 is inclined along the road surface f as shown in FIG. You will get it. Moreover, since the distance between the horizontal pipe 25 and the receiving pipe 15 can be finely adjusted through the long hole 26, the distance error between the car stop columns 1 and 1 can be adjusted only by changing the exposed gap of the inner pipe 30. It will be possible. Further, in the connection mode, the receiving pipe 15 having the same diameter and the lateral pipe 25 are continuous with each other, and an appearance like a series is exhibited and no discomfort is caused.

In the above configuration, the arc-shaped guide surface 14 may be concave and the arc-shaped sliding surface 18 may be convex.

FIG. 5 shows the above-described basic structure, in which the spring support pieces 40, 40 (only one of which is shown) are mounted in the lateral pipe 25, and the springs 41, 41 are housed from both ends thereof. The inner end is held by the spring support pieces 40, 40, and the spring 41 is used to elastically contact the inner end of the inner pipe 30. In such a structure, when connecting the horizontal pipe 25 between the column main bodies 2 and 2, first, the screws 33 and 34 are pushed inward with a finger, and the inner pipe 30 is resisted against the springs 41 and 41. , The retracted position is stored in the horizontal pipe 25, the horizontal pipe 25 is aligned and passed between the receiving pipes 15 and 15, and the retracting operation by the finger of the screw 33 is released. Then, the inner pipe 30 is fitted into the receiving pipe 15 by the urging force of the spring 41, the screw hole 32 is communicated with the through hole 19 of the receiving pipe 15 as described above, and the screw 34 is inserted into the through hole. The horizontal pipe 25 is connected between the column main bodies 2 and 2 by screwing from 19 to the screw hole 32 and tightening the screws 33 and 34 further.

In such a structure, there is an advantage that the inserting operation of the inner pipes 30, 30 is facilitated by the urging force of the springs 41, 41.

[Effect of device]

 As described above, according to the present invention, the arcuate sliding surface that is in close contact with the fixing metal fitting 12 is provided on the end face through the fixing metal fitting 12 on the outer surface of which the vertical arcuate guiding surface 14 is formed on the side surface of the car stop strut 1. The receiving pipe 15 on which 18 is formed is fixed, and the guiding action of the arcuate guide surface 14 and the sliding surface 18 makes it possible to tilt the receiving pipe 15 about the arc center as a rotation center, and the lateral pipe 25. Since the rear pipes are connected to the receiving pipes 15 and 15 of the adjacent car stop struts 1 and 1 so as to be passed over, even when the car stop struts 1 are fixed to the inclined road surface f, the struts 1 and 1 are also fixed. Since the horizontal pipe 25 can be placed in parallel with the slope, it can be applied not only to a horizontal road surface but also to various road surfaces, and the versatility of this kind of car stop strut 1 and the horizontal pipe 25 can be improved. It has an excellent effect.
