The present invention will be explained in detail below with reference to Examples.

Reference numeral 1 denotes a support section such as a column, and the base ends of a pair of support arms 2 are rotatably supported at the upper ends of the support sections 1 disposed on the left and right sides, respectively. Reference numeral 3 denotes a door face body formed, for example, in a vertical lattice shape, and the distal end portions of the respective support arms 2 are connected to vertical frames 6 on both left and right sides of the door face body 3. Then, when the door face body 3 is turned vertically as shown in FIGS. 1 and 2, it is closed.
It is designed to be released when the door face body 3 is turned horizontally above the sea urchin shown in Figure tj&3. The vertical stile 6 has a square pipe shape with a hollow interior, and has a U-shaped vertical groove 7 with a lip in cross section extending in the operator's direction on the side to which the support arm 2 is connected. A fixing plate 8 in the form of a rectangular plate is installed inside the vertical groove 7 so as to be slidable up and down, and a punching hole 13 is formed in the fixing plate 8.

Reference numeral 9 denotes an arm mounting bracket, and the opening-shaped fitting part 14.
It is constructed by having mounting pieces 10 extended from the two lower ends. A long hole 11 is bored in the mounting piece 10 in the horizontal direction, and a locking piece 15 having a cross-sectional path I5 shape is extended from the center of the lower end of the lower mounting piece 10 in the width direction. The width of the protruding base of the locking piece 15 is narrower than the width of the opening on the side surface of the vertical groove 7, and the width of the tip is wider than the width of the opening. The fitting portion 14 has a size such that it can fit into the tip of the support arm 2, which is hollow inside, and is provided with a tapped hole 16.

A through hole 17 is bored at the tip of the support arm 2. The arm mounting bracket 9 is constructed by inserting the locking piece 15 into the vertical groove 7 from the longitudinal end of the vertical stile 6, and inserting the mounting piece 10 into the vertical groove 7.
is arranged on the outer surface side of the vertical stile 6 so as to be in contact with the outer surface side of the vertical stile 6,
The arm mounting bracket 9 is fixed to the vertical stile 6 by screwing the door mounting bolt 12 into the screw hole 13 through the elongated hole 11. The fitting part 14 of the arm mounting bracket 9 is fitted into the tip of the support arm 2, and the arm mounting bolt 18 is inserted into the screw hole 1 through the through hole 17.
The tip of the support arm 2 is fixed to the arm mounting bracket 9 by screwing into the support arm 6. At this time, by loosening the door mounting bolt 12, the fixed plate 8 can be slid up and down to adjust the vertical position, or the elongated hole 11 can be slid against the door mounting bolt 12 to adjust the horizontal position. The arm mounting bracket 9 can be aligned with the tip of the support arm 2. After adjusting the position of the arm mounting bracket 9 with respect to the tip of the support arm 2, the door mounting bolt 12 is tightened and fixed. At this time, the cut-and-raised piece 19 on the bottom of the vertical groove 7 is cut and raised at a position corresponding to the tip of each door mounting bolt 12. Then, the cutting piece 19 is positioned above the tip of each door mounting bolt 12, and even if the door mounting bolt 12 becomes somewhat loosened and the fixing plate 8 is able to slide, the tip of the door mounting bolt 12 is cut and raised. The fixing plate 8 will not come off upward together with the arm mounting bracket 9 by being locked to one piece. Furthermore, even if the door mounting bolt 12 is completely removed, the locking piece 15 will be locked to the opening edge (limp part) of the vertical groove 7, and the arm mounting bracket 9 will not come off from the opening on the side of the vertical groove 7. The piece 15 is locked to the cut-and-raised piece 19, and the fixing plate 8 will not come off together with the arm mounting bracket 9.

[Effects of the Invention] As described above, the present invention provides longitudinal grooves in the longitudinal direction of the vertical stile of the door face body in the shape of a cross section with a lip, and also includes a fixing plate inside the vertical groove, and the outer surface of the vertical groove of the vertical stile Place the arm mounting bracket on the side, and screw the door mounting bolt into the fixing plate from the outside of the mounting piece that is in contact with the outside of the vertical stile of the arm mounting bracket to secure the arm mounting bracket to the vertical stile. When the plate slides in the longitudinal direction of the U1 groove, a cut-and-raised piece that can be locked by the tip of the mounting bolt is cut and raised from the bottom of the vertical groove, so even if the door-mounting bolt is loosened, the fixed plate will still slide. This prevents the fixing plate from coming off upward along with the arm mounting bracket, and since the locking piece extending from the arm mounting bracket is positioned within the vertical groove, the locking piece is The locking piece will not come off from the vertical stile even if the door mounting bolt comes off when it is locked in the vertical groove, and furthermore, when the fixing plate slides in the longitudinal direction of the vertical groove, the tip of the locking piece will be cut and raised. Even if the door mounting bolt is removed, the locking piece will lock onto the cut-and-raised piece and the fixed plate will not be able to slide. The fitting part of the arm mounting bracket is fitted into the tip of the hollow support arm, and the arm mounting bolt is screwed into the fitting part from the outer surface of the tip of the support arm. Since the tip wlI portion of the support arm is fixed to the arm mounting bracket, the support arm can be reliably mounted to the arm mounting bracket by fitting the fitting portion and screwing in the arm mounting bolt. . Therefore, according to the present invention, the door face piece can be reliably attached to the support arm, and there is no danger of the door face piece coming off and the support arm flying up and hitting someone's head, or causing injury when the door face piece falls over. It can be used safely without any damage.
