Description

[Detailed Description of the Invention] The present invention relates to the improvement of handrails installed on building balconies, parks, etc., for example.

Conventional handrails have a large number of standers arranged in a grid pattern between upper and lower rails, and each stand and rail are usually fixed by spot welding.

In the case of such welding and fixing, it is unavoidable that the manufacturing work requires a large amount of time and effort for positioning, temporary attachment, main welding, finishing by grinding, painting, etc., and there is a particular inconvenience that corrosion may occur from the spot welded parts. there were.

In order to prevent this, in recent years a structure has been proposed in which each stand is screwed to the crosspiece.

However, it is not easy to provide a screw hole in the upper end surface of a stand which is a hollow body, and both methods require time and effort to form the screw hole, causing a decrease in manufacturing efficiency and an increase in cost.

The object of the present invention is to provide a handrail that solves the problems of the conventional handrail at once by providing a new structure that allows a stop plate with screw holes to be easily attached to the upper end opening of the stand.

The present invention will be specifically described below based on embodiments shown in the drawings.

As is well known, the handrail in the illustrated example has upper and lower rails 2 and 3 orthogonally supported between columns 1 and 1 that are vertically installed at a constant interval, and a grid that is equally spaced between the upper and lower rails 2 and 3. The stand 4 is arranged vertically in a manner similar to the above.

The upper crosspiece 2 consists of a receiving frame 21 and a cover 26 that is engaged with the frame 21 and surrounds the front, rear, and upper parts thereof, and the receiving frame 21 has a lower opening engagement groove into which the upper end of the stand 4 fits. 22, and a stopper hole 23 is formed in the bottom wall of the groove at a spacing between the studs.

On the other hand, each stand 4 is made of a pipe material with a square cross section, and the upper end is provided with a plurality of protrusions 41 by stamping on the inner surface of the pipe slightly downward from the upper end, and the upper end of the opposite side wall is provided with claw pieces 42.4.
2 is formed, and a stop plate 43 having a screw hole 44 is fitted to the upper end of the pipe, supported by the protrusion 41, and fixed by bending the claw pieces 42 and 42.

The upper end of the stand 4 is fitted into the engagement groove 22 of the receiving frame 21 so that the locking hole 23 and the screw hole 44 are aligned, and the locking screw 24 is screwed in from above to tighten and fix.

In the receiving frame 21, the lower portions of both groove walls are provided with engaging grooves 25, 25 that open inwardly toward each other, while the cover 26
The lower portions of the front and rear walls are bent inwardly and the ends thereof are bent outward to form retaining sides 27, 27. The cover 26 is placed over the receiving frame 21 and the engaging side 27 is engaged with the engaging groove 25. It matches.

Incidentally, the end of the upper crosspiece 2 is fixed by screwing the receiving frame 21 to the L-shaped metal fitting 5 fixed to the support column 1.

As described above, the present invention does not use a fixing structure by welding, but connects the upper rail 2 and the stand 4 with screws, so there is no corrosion, and the appearance and durability of the handrail can be improved.

Further, the stop plate 43 having a screw hole 44 is fitted into the upper end opening of the stand 4, and the stop plate 43 is held between the protrusion 41 formed on the stand 4 and the claw plate 42, so that the stop plate 43 After the retaining plate 43 is fitted, the screw hole 44 can be formed very easily on the upper end surface of the stand by simply bending the claw plate 42.
No special parts are required for fixing the device, contributing to improved manufacturing efficiency and reduced costs.The structure is simplified and has effects that are distantly related to the original purpose of the invention.
