(Other embodiments)
As described above, as the handrail of the present invention, the embodiment in which the panel upper frame 52 of the panel unit 5 is supported by the panel upper support means 2 fixed to the support column 1 has been described. However, the handrail of the present invention is the panel unit 5. It suffices if the support means 2 on the panel that supports the above can be arranged at a predetermined height, and may be supported by, for example, the wall surface of the balcony shown in FIG.
For example, when the end of the support means 2 on the panel is close to the wall surface of the building, the end of the support means 2 on the panel may be arranged at a predetermined height via the wall bracket 7 fixed to the wall surface. it can. The wall bracket 7 fixed to the wall surface of the building is composed of, for example, a vertical surface portion 71 for fixing to the wall surface and a mounting surface portion 72 for mounting and fixing the support means 2 on the panel, and the wall bracket 7 is vertical. The surface portion 71 is formed with screw holes for fixing to the wall surface as elongated holes 71a long in the vertical direction.
As a result, the height position of the wall bracket 7 can be finely adjusted with respect to the wall surface. For example, even when used in combination with the support column 1, the height of the end portion of the support means 2 on the panel is adjusted to match the height of the support column 1. The position can be determined accurately.

(Panel unitized structure)
The handrail according to the embodiment of the present invention has the above-mentioned structure as the handrail and also has the following panel unit structure. Hereinafter, description will be made with reference to the drawings.
The handrail according to the present embodiment is provided with a panel upper frame 52 and a panel lower frame 53 on the upper and lower sides of a panel 51 such as glass in order to facilitate on-site construction. The work can be simplified and the construction period can be shortened.
Then, in order to securely fix the unitized panel unit 5 to the support columns 1 and the like, an upper locking piece 522 is formed downward from the panel upper frame 52 of the panel unit 5, and the panel upper support means. A locking piece portion 221 is formed upward from the upper surface of the extension portion 22 of 2.
By forming the locking piece portion 221 of the panel upper support means 2 so as to extend upward in this way, the upper locking piece 522 locked inward of the locking piece portion 221 is screwed from above. Since it can be fixed by the fixing means N such as (FIG. 8A), both can be securely fixed. Further, since the panel upper support means 2 and the panel upper frame 52 integrated by screw fixing are integrated by the cap tree 6, both are more firmly fixed.

Similarly, the lower locking piece 532 is formed downward from the panel lower frame 53 of the panel unit 5, and the vertical portion 42 is formed upward from the inner end portion of the horizontal portion 41 of the panel lower support means 4. The lower locking piece 532, which is in contact with the inside of the vertical portion 42 and locked, can be fixed from above by a fixing means N such as a screw (FIG. 8 (b)). It is possible to securely fix the panel unit 5 and prevent the panel unit 5 from falling off to the outdoor side (opposite to the support column).
Further, the panel lower support means 4 for supporting the panel lower frame 53 is fixed to the support column via the bracket 3, and the panel lower support means 4 is mounted on the bracket 3 positioned with respect to the support column 1. Since it can be placed and fixed by fixing means such as screws, it is not necessary to hold the panel lower support means 4 horizontally at the time of construction, and the construction can be performed reliably and easily. Further, when the panel lower frame 53 is directly fixed to the support column 1 with screws or the like, the load of the panel unit 5 is concentrated on the screws, whereas the panel lower support means 4 for supporting the panel lower frame 53 is attached to the support column 1. On the other hand, when the load is fixed via the bracket 3, the load of the panel unit 5 can be distributed to the bracket, and the local load can be reduced.

Further, the panel lower frame 53 is formed with a hanging piece 533 whose outer surface hangs downward, and the hanging piece 533 of the panel lower frame 53 abuts on the outer side of the falling prevention piece 32a of the bracket 3 while bracketing. Since it is fixed to the panel lower support means 4 screwed and fixed to 3, it can be integrally fixed as a whole, and the panel unit 5 can be prevented from falling off to the indoor side (post side). ..

As described above, the wall material constituting the handrail is composed of the panel, the panel upper frame, and the panel lower frame, and is locked to the upper locking piece of the panel upper frame and the lower locking piece of the panel lower frame. Since the portion is formed by the locking piece portion and the vertical portion extending above the panel upper supporting means and the panel lower supporting means, the upper locking piece of the panel upper frame and the lower locking piece of the panel lower frame are formed. After locking, it can be fixed by screwing from the upper position, and fixing can be performed easily and reliably.
