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.

To prevent this, a structure in which each stand is screwed to the crosspiece has been proposed in recent years, but the crosspiece is easily deformed, especially when pressure is applied to the lower crosspiece, and the strength is lower than that of a welded joint structure. There was a disadvantage that the value decreased.

The object of the present invention is to solve the above-mentioned problems at once with a simple structure, and to provide a new handrail that is excellent in strength and durability and is easy to assemble.

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 4 orthogonally supported between columns 1 and 1 that are vertically installed at regular intervals, and a grid that is equally spaced between the upper and lower rails 2 and 4. The stand 3 is arranged vertically in the form of a structure, and the present invention is characterized by the connection structure between the lower crosspiece 4 and each stand 3.

That is, the lower crosspiece 4 has a gutter-like cover 46 that covers the lower end of each stand 3.
and a receiving plate 41 which is disposed opposite to the lower end surface of each stand 3 and supports and fixes the cover 46.

The cover 46 is made by pressing metal silver into a downward gutter shape, and has insertion holes 47 formed at equal intervals in the earthen wall to match the cross-sectional shape of the stand.
In addition, the upper end of the folded piece is further bent inward to form the mounting wall 48.
．． 48, and the ends of both mounting walls 48 are folded back and bent downward to form engaging protrusions 49 and 49.

The receiving plate 41 includes a stand receiving surface 43 that is fitted between the mounting walls 48, 48 of the cover 46, a screw hole 40 is provided in the center of the receiving surface 43, and the above-mentioned screw hole 40 is formed on both side edges by press processing or the like. Upper opening retaining grooves 44,44 that engage with the protrusions 49 are formed, and the upper edges of the bent pieces 45,45 on the outside of each retaining groove 44 are lowered by the thickness of the cover 46, respectively. There is.

Each stand 3 has protrusions 31, 31 formed on opposite edges of the lower end, and a stop plate 5 with a screw hole 51 is inserted into the stand 3, and the protrusions 3
1 and 31 are bent inward to support the stop plate 5.

The ends of the upper crosspiece 2 and lower crosspiece 4 are screwed to the L-shaped fittings 6 and 7 attached to the support column 1, and in FIG. It is a metal fitting.

Then, the lower end of the stand 3 is inserted into each insertion opening 47 of the cover 46, and the lower end surface of the stand 3 is placed on the mounting wall 48.48.

Next, the receiving plate 41 is made to face the lower end surface of the stand 3, and the receiving plate 41
While fitting the receiving surface 43 between the mounting walls 48, 48 and engaging the protrusion 49 into the engagement groove 44, insert the setscrew between the screw holes 40, 51 of the receiving plate 41 and the stop plate 5. 42 is threaded, and the mounting walls 48, 48 of the cover 46 are tightened and fixed between the lower end surface of the stand 3 and the receiving plate 41.

As described above, in the present invention, each stand 3 is connected to the insertion hole 4 of the cover 46.
Since the cover 46 is tightened and fixed by the receiving plate 41 through the lower crosspiece 4, the lower crosspiece 4 has a better appearance than the conventional welded structure.In particular, since a retaining part is formed between the cover 46 and the receiving plate 41, Even if tread pressure is applied to the cover 46 and a force in the opening direction is applied to both mounting walls 48, 48, the protrusion 49 at the tip of the mounting wall 48 will not hold the support plate 4.
Since the cover 46 is engaged with the engagement groove 44 of No. 1 and prevented from escaping from the groove 44, there is no risk that the cover 46 will be deformed or separated from the stand 3. It has a distantly related effect.
