DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1A is an end view showing an embodiment of a handrail according to the present invention, and shows a state in which a trunk 3 and a cap 4 are connected. The rim 3 and the cap 4 are made of an extruded profile made of an aluminum alloy, the rim 3 has an upper opening structure, and the skirt 4 has a lower opening structure.

Reference numerals 10 and 11 denote locked portions provided on the upper and lower portions of the side plate portion 5 of the body edge 3, respectively.
0 designates the lower surface a as an inclined surface (an R surface may be used). The locked portion 11 is formed as a protruding piece that protrudes laterally below the side plate portion 5 of the body edge 3.

On the other hand, on the inner surface of the side plate 7 of the coping 4, locking portions 12, which are locked by the locked portions 10, 11, respectively, are provided.
13, and a restricting piece 15 that is in contact with the upper horizontal portion 14 of the body edge 3 is formed to protrude inward. The lower surfaces of the locking portions 12, 13 are formed as inclined surfaces b, c.

As shown in FIG. 6, attachment of the cap 4 to the rim 3 is performed by pressing the cap 4 against the rim 3 fixed to the column 2 so as to cover the rim 3 from above. . As a result, first, the lower locking portion 13 of the cap 4
The lower inclined surface c of the main body 3 comes into contact with the locking portion 10 of the body edge 3 and flexes due to the flexibility of the side plate portion 7 of the coping 4. At the same time, the side plate portion 5 of the body edge 3 also deforms inward due to flexibility. As a result, the locking portion 13 exceeds the upper locked portion 10 of the upper rim 3, and further, exceeds the lower locked portion 11, and the locking portion 13 is locked to the locked portion 11. You. Also, the upper locking portion 12 of the cap 4
Is also locked to the lower inclined surface a of the upper locked portion 10 by the same operation, and the restricting piece 15 abuts on the upper horizontal portion 14 of the body edge 3, thereby connecting the cap 4 to the body edge 3. .

When removing the cap 4 from the rim 3, FIG.
As shown in (B), the lower edge of the side plate 7 of the cap 4 and the trunk 3
When the tool 20 such as a screwdriver is inserted into the gap g between the lower portion of the side plate portion 5 and pivoted to open it, the cap 4 is centered on the tip of the locking portion 13 on the right side in the drawing of FIG. 2A, the locking of the left locking portion 13 on which the driver is inserted by the locked portion 11 is released, and thereafter, FIG.
