Abstract

PROBLEM TO BE SOLVED: To adjust a securing inclination of a beam in the wide range by pivoting a male coupling of a cap to be fitted in the head of a pillar and a male coupling of a receiving metal piece to be fastened on a beam, and forming the upper surface of the female coupling and lower surface of the male coupling into an circular arcuate projection respectively. SOLUTION: A branched female coupling 6A of a cap 6 to be fitted in the head portion of a pillar 7 and the male coupling 8A of a receiving metal piece 8 to be fastened to a beam 9 are pivoted. Also, the upper surface of the female coupling 6A and the lower surface of the male coupling 8A are formed into a circular arc respectively. In addition, one portion of the female coupling is threaded to screw with a horizontal bolt. As a result, even in situations where the male coupling 8A rotates widely, it does no interfere with the female coupling 6A. Accordingly, an inclination of the beam 9 in a vertical plane including the axis of the pillar 7 can be adjusted in a wide range. Moreover, no exposure of other portions but head portion of the horizontal bolt 11 creates excellent appearance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guard pipe joint, and more particularly, to a guard pipe having an excellent appearance in which a beam mounting inclination angle in a vertical plane including an axis of a column can be adjusted in a wide range. The present invention relates to a joint for use in a vehicle.

2. Description of the Related Art Conventionally, as shown in FIG. 10, in a guard pipe formed by fixing a handrail beam 2 made of a round pipe or the like to the upper end of a support column 1, the support column 1 and the beam 2 are as follows. Was fixed. That is, bolt holes 1A and 2A are formed in the top plate 3 and the beam 2 of the column 1, and the U-shaped bolt 4 is inserted through the bolt holes 1A and 2A to
To conclude.

[0003]

However, when the terrain where the guard pipe is to be installed is inclined, the beam 2 cannot be fixed to the column 1 obliquely in accordance with the inclination of the terrain. I had to deal with it by adjusting it, which was inefficient.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a joint for a guard pipe which can adjust a mounting inclination angle of a beam in a wide range in a vertical plane including an axis of a column and has an excellent appearance. is there.

[0005]

According to the first aspect of the present invention,
In a guard pipe joint for fixing the beam to the head of the column so that the angle can be adjusted in a vertical plane including the axis of the column, the beam is fitted into the head of the column.
A cap having a bifurcated female joint on the upper surface, and a receiving fixture having a male joint fixed to the beam and having a lower surface capable of being angle-adjusted to the female joint by a horizontal bolt on the lower surface, the upper surface of the female joint and The lower surfaces of the male joints are each formed in a convex shape in an arc shape, and thus the angle of attachment of the beam in the vertical plane can be adjusted over a wide range.

The invention according to claim 2 is characterized in that the receiving bracket is connected to the cap so that the angle can be adjusted by a horizontal spring pin instead of the horizontal bolt.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a guard pipe joint according to an embodiment of the present invention.

FIG. 1 is a partially cutaway front view showing a guard pipe joint of the present invention, FIG. 2 is a side view showing a guard pipe joint of the present invention, and FIG. 3 is a guard pipe joint of the present invention. , FIG. 4 is a plan view showing the cap of the guard pipe joint of the present invention, FIG. 5 is a side view showing the cap of the guard pipe joint of the present invention, and FIG. FIG. 7 is a front view showing a receiving fitting in the guard pipe fitting, FIG. 7 is a bottom view showing the receiving fitting in the guard pipe fitting of the present invention, FIG. 8 is a side view showing the receiving fitting in the guard pipe fitting of the present invention, FIG. 9 is a front view showing a bolt for connecting the cap and the receiving fitting in the joint for a guard pipe of the present invention.

In FIG. 1 to FIG. 9, reference numeral 6 denotes a cap fitted into the head of the column 7, and a forked female joint 6A is formed on the upper surface thereof. One of female joint 6A 6
A1 is threaded with a horizontal bolt 11 to be described later. The upper surface of the female joint 6A is formed to be convex in an arc shape.

Reference numeral 8 denotes a receiving bracket fixed to the beam 9 by bolts 10. On its lower surface, a male joint 8A is formed on the female joint 6A of the cap 6 so as to be freely adjustable in angle by a horizontal bolt 11. ing. The lower surface of the male joint 8A is formed to be convex in an arc shape. Note that a horizontal spring pin may be used instead of the horizontal bolt 11.

According to the joint for a guard pipe of the present invention configured as described above, a guard pipe is constructed as follows. First, the cap 6 is fitted into the head of the column 7 and fixed. Next, the female joint 6 of the cap 6
The male joint 8A of the receiving metal fitting 8 is fitted between A. Next, the horizontal bolt 11 is inserted into the female joint 6A and the male joint 8A and tightened.

In this manner, the receiving member 8 is
Is fixed at a predetermined inclination angle, the end of the beam 9 is placed on the receiving fitting 8 via the inner sleeve 12, and is fixed with the bolt 10. Thus, a guard pipe is constructed.

As described above, the female joint 6A and the male joint 8A are pivotally supported by the horizontal bolt 11, and the upper surface of the female joint 6A and the lower surface of the male joint 8A are each formed in a convex shape in an arc. Therefore, even if the male joint 8A rotates over a wide range, it does not interfere with the female joint 6A. Therefore, the mounting inclination angle of the beam 9 in a vertical plane including the axis of the column 7 can be adjusted over a wide range. Moreover, since only the head of the horizontal bolt 11 is exposed from the joint, an excellent appearance can be obtained. This effect appears more remarkably by replacing the horizontal bolt 11 with a horizontal spring pin.

[0014]

As described above, according to the present invention, the female joint of the cap fitted into the head of the column,
Adjusting the mounting inclination angle of the beam over a wide range by supporting the male joint of the receiving fixture fixed to the beam and forming the upper surface of the female joint and the lower surface of the male joint in a convex shape, respectively. Can be. Moreover, since there are few members exposed from the joint, useful effects such as obtaining an excellent appearance can be obtained.
