Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a cap mounting structure for a fence strut in an exterior fence.

(Prior Art) Conventionally, a fence strut and a cap are attached by, for example, a method of welding a cap covering the upper end of the strut, a method of screwing the outer peripheral surface of the cap to the strut, or a plurality of methods on the outer peripheral surface of the upper end of the strut. This is done by forming a hole, and caulking only the portion of the cap that covers the column corresponding to the hole from the outside to make it engage with the hole.

(Problems to be solved by the invention) However, in the case of the above-mentioned welding, there is a problem that it is necessary to perform a finishing work after welding and it takes a lot of time to install the welding portion, and the welded portion has a bad appearance. In the case of screw fixing, it is necessary to process so that the screw can be fixed on the support or the cap side, and it takes time and labor for the processing and screw fixing, and there is a problem that the screw is exposed and the appearance is spoiled. . Further, when caulking a plurality of portions of the cap, the caulked outer peripheral surface of the cap is dented, and there is a problem that the appearance is damaged.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the cap mounting structure of the fence post of the present invention has a protrusion or a plurality of protrusions provided in the circumferential direction on the outer surface of the upper end of the pillar, the inner surface of which is A cap having a mounting cylinder part corresponding to the outer peripheral shape and having an inner diameter substantially equal to the strut outer diameter and gradually expanding toward the lower end from the upper end is attached to the upper end part of the strut by externally mounting the mounting cylinder part. And the stopper step provided on the upper end of the inner surface of the mounting cylinder is brought into contact with the upper end surface of the column, and the mounting cylinder is uniformly crimped from the outside to engage with the ridge or projection. Is.

(Example) Hereinafter, the present invention will be described with reference to the drawings.

In the drawings, (1) is a column, and a metal tube is generally used. The cross-sectional shape of the support column (1) is generally circular, but it may be of any suitable shape such as a quadrangle, a polygon, or an ellipse. A protrusion (11) or a plurality of protrusions (12) are provided on the outer surface of the upper end of the support column (1) in the circumferential direction. For example, in the case of FIG. 1 and FIG. 2, the support wall (1) has its peripheral wall deformed by press working or the like so that a plurality of protrusions (12) are provided in the circumferential direction. In the case of FIG. 3 as well, the peripheral wall of the column (1) is similarly deformed so that the ridges (11) project in the circumferential direction. Further, the protrusions (11) and the protrusions (12) may be provided on the outer peripheral surface of the column (1) without deforming the peripheral wall of the column (1). The shapes of the ridges (11) and the projections (12) are not particularly limited, such as a mountain shape in cross section and a semicircular shape.

(2) is a cap, which is generally made of metal or the like. The cap (2) is formed of a mounting cylinder part (21) and a lid part (22) that closes one opening of the cylinder part (21). The mounting cylinder portion (21) has an inner surface corresponding to the outer peripheral shape of the support column (1). For example, when the pillar (1) has a circular cross-sectional shape, the inner surface of the mounting cylinder (21) is also circular. The inner surface of the mounting tube portion (21) is an inclined surface that gradually expands toward the lower end from the upper end having an inner diameter substantially equal to the outer diameter of the column (1), and even if the inner surface is simply smooth. Good, the groove (23) corresponding to the ridge (11) and the protrusion (12) of the column (1) as shown in FIG.
May be provided. Further, a step portion (24) is generally provided at the upper end portion of the inner surface of the mounting cylinder portion (21) to serve as a stopper when the pillar (1) is covered. Although the lid portion (22) has a cone shape in the drawing, it may have an appropriate shape such as a simple flat plate shape.

Then, the cap (2) is covered by inserting the mounting tube portion (21) onto the upper end of the support column (1), and the mounting tube portion (21) is externally attached by the jig (3) as shown in FIG. It is crimped uniformly, and the inner surface of the mounting cylinder portion (21) is engaged with the protrusion (12) as shown in FIG. 1 or the protrusion (11) as shown in FIG. When the outer periphery of the mounting cylinder portion (21) is provided with irregularities (25) from the surface of decorative effect as shown in FIG. 5, the inner surface has irregularities (31) corresponding to the irregularities (25). It suffices that the jig (3) be used to crimp the mounting tube portion (21).

(Effects of the Invention) As described in detail above, in the cap mounting structure of the fence post of the present invention, a protrusion or a plurality of protrusions are provided on the support column in the circumferential direction, and the mounting tube portion of the cap covered by the support is outward. Since it is uniformly caulked from the above and is engaged with the above-mentioned ridge or projection, it is possible to keep the cap lid in various shapes without damaging it, and the cap can be easily and uniformly attached. In terms of appearance, there are no welded parts, screws, or dents due to caulking as in the past, and there is no loss of appearance.

In addition, the inner surface of the mounting cylinder portion is an inclined surface that gradually widens toward the lower end from the upper end of the inner diameter that is almost equal to the outer diameter of the column, and a stopper step is provided at the upper end of the inner surface. Since the step is put on the support and the step comes into contact with the upper end of the support, the mounting cylinder can be easily covered up to the predetermined position of the support before the mounting cylinder is crimped, and the cap mounting work is uniform. Easy to do.
