Abstract

PROBLEM TO BE SOLVED: To prevent a convex mirror itself from becoming bulky or increasing in weight, and to install it so as not to create a gap between two orthogonal wall surfaces such as an L-shaped road. Further, the convex mirror side may be processed at one place for mounting, and further provides a mounting structure for the convex mirror that can be slightly moved in the vertical direction even after mounting. SOLUTION: One end of a tension coil spring 3 is located at the center of three arc-shaped end sides 1b and 1c of a convex mirror made of a spherical plate 1 having a convex surface of a one-eighth spherical body as a mirror surface near the one-arc-shaped end side. The other end of the tension coil spring 3 is spring-forced to the support member 2 of the fixture which is attached to the corner portion where the two wall surfaces Wa and Wb are orthogonal to each other so as to straddle the two wall surfaces Wa and Wb. In the obtained state, the mirror is locked so that the other two-arc-shaped end sides 1b and 1c of the convex mirror are brought into contact with the two wall surfaces Wa and Wb.

As shown in FIGS. 1 to 4, the support member 2 of the fixture B has contact pieces 2 a and 2 a that are in contact with the two wall surfaces Wa and Wb so as to straddle the two orthogonal wall surfaces Wa and Wb of the corner portion. It is assumed that it was provided. Then, stop holes 6 are provided at both ends of the abutting pieces 2a and 2a, screws are screwed into the two wall surfaces Wa and Wb from these stop holes 6 or nails are driven into the support member 2 so that the two wall surfaces Wa, It can be attached to Wb. These rely pieces 2a, it is between 2a and that provided a support piece 2b, and assumed that further provided with a locking hole h ₂ of the coil spring 3 tensile to the support piece 2b.

As shown in the figure, the supporting member 2 is formed by bending a long metal plate or a synthetic resin plate into a substantially square shape by 90 ° to form the abutting pieces 2a and 2a. multiplied pass as assumed in which a support piece 2b made of a metal plate or a synthetic resin plate elongated between 2a, as the locking hole h ₂ is provided in a central portion of the bottom side near the support piece 2b Yes. Incidentally, the engagement of the stop hole h ₂ provided at the lower edge side of the support piece 2b, as described later, orthogonal two-wall Wa of the corner portion, in high altitude operations, such as mounting above the Wb, tensile This is because the coil spring 3 is easily locked.

Further, as shown in FIG. 5, the support member 2 is bent at 135 ° inside both ends of a long metal plate or synthetic resin plate, and the bent portions are made into contact pieces 2a and 2a, and are not bent. and that the portion and the support piece 2b, it may be that the locking hole h ₂ in the central portion of the bottom side near the support piece 2b is provided.

Further, as shown in FIG. 6, the support member 2 is formed by bending a long metal plate or synthetic resin plate into a substantially square shape by 90 ° to form the contact pieces 2a and 2a. 2a, it is assumed in which a support piece 2b made of a metal plate or a synthetic resin plate so as to protrude from 2a of the lower end side, the locking hole h ₂ is provided in a central portion of the end side near the support piece 2b It may be a thing.

The tension coil spring 3 connects the convex mirror A and the support member 2 in a spring-biased state, and is engaged with the locking hole h ₁ of the spherical plate 1 of the convex mirror A at one end. the hooks 3a to be sealed is provided, it is assumed in which a hook 3b which are engaged the the locking hole h ₂ of the support piece 2b of the support member 2 at the other end. Incidentally, the tension hook 3a of the coil spring 3 is directly locking holes h ₁ of the spherical plate 1 of the convex mirror A, without locking, the locking by the locking member 4 to be described below is interposed You can also.

The locking member 4, as shown, and those projecting shaft portion 4b in the center of a circular plate-like head 4a, is assumed in which a locking hole h ₃ to the shaft portion 4b, the through the shaft portion 4b in the locking hole h ₁ of the spherical plate 1 of the convex mirror a, the tension coil spring spherical plate 1 of the convex mirror a stop at the head 4a, the engaging holes h ₃ of the shaft portion 4b 3 hooks 3a are locked.

  In the convex mirror mounting structure of the present invention as described above, since the convex mirror A to be used is composed of the spherical plate 1 with the convex surface of the eighth spherical body as the mirror surface, the convex mirror itself is bulky. In other words, the weight does not increase, and it is easy to attach to two orthogonal wall surfaces Wa and Wb of the corner portion such as an L-shaped path, and there is no risk of dropping.

  And the mounting structure of the convex mirror of this device is such that the two arc sides 1b and 1c of the convex mirror A are brought into contact with the two wall surfaces Wa and Wb in a state where the spring bias of the tension coil spring 3 is obtained. Since the convex mirror A can be slightly moved in the vertical direction, even if a gap is formed between the convex mirror and the ceiling after the convex mirror is mounted, the convex mirror A can be moved upward. The gap is not generated, and dust or dust does not enter the gap, and the dust or dirt does not accumulate inside the convex mirror A and become dirty.

Furthermore, the mounting structure of the convex mirror of this invention is a three arcuate end edges 1a of the convex mirror A, 1b, of providing the locking holes h ₁ to the central portion of one arcuate end edges 1a close of 1c, one Since it is sufficient to process only the portion, the labor of the processing is reduced, and the convex mirror A can be easily attached.

  In addition, since the convex mirror mounting structure of the present invention can move the convex mirror A slightly in the vertical direction as described above, if the convex mirror A is moved in the vertical direction even after mounting the convex mirror A, The reflection angle of the convex mirror A can be finely adjusted.
