Abstract: A handrail jointer which is most suitable to install a handrail easily at a placing site even on a slope which is bent and has a complicated shape having a varying inclination. The handrail jointer 1 comprises the post connector 10 connected to the post 5, the handrail holders 31, 32 having the handrail holding portions 31a, 32a holding the handrail members 7, and the elbow body 20 attached to the post connector 10 and having the fitting portions 23, 24 for fitting the handrail holders 31, 32. These handrail holders 31, 32 are rotatably attached at certain angles to the fitting portions 23, 24 so that the handrail holders 31, 32 can rotate in a neck roll exercise manner on the fitting portions 23, 24.

Abstract: A leveling assembly for setting a vertical prop is comprised of an inclined surface setting member 20 and a horizontal surface forming member 30. The horizontal surface forming member 30 has a horizontal surface 32 to be adjusted to a horizontal position and an opposite first adjusting surface 31 that is not parallel to horizontal surface 32. The inclined surface setting member 20 has a setting surface 21 facing a slope inclined surface 11 and an opposite second adjusting surface 22 facing the first adjusting surface 31 which is not parallel to the setting surface 21. The horizontal surface forming member 30 and the inclined surface setting member 20 are placed on top or each other, and the horizontal surface 32 is adjusted to the horizontal position relative to the slope inclined surface 11 by rotating the members relative to each other to change the degree angle between the horizontal surface 32 and the setting surface 21.

Abstract: A leveling assembly for setting a vertical prop comprised of inclined surface setting member 20 and horizontal surface forming member 30 wherein; the horizontal surface forming member 30 has a horizontal surface 32 to be adjusted as being horizontal and a first adjusting surface 31 formed by surface not parallel to horizontal surface 32, the inclined surface setting member 20 has a setting surface 21 facing a slope inclined surface 11 and a second adjusting surface 22 facing the first adjusting surface 31 formed by a surface not parallel to setting surface 21, and, the horizontal surface forming member 30 and inclined surface setting member 20 to be piled up to make the first adjusting surface 31 and the second adjusting surface 21 next to each other, and, the horizontal surface 32 to be horizontal to the slope inclined surface 11 by rotating relatively the position and changing degree between the horizontal surface 32 and the setting surface 21.
