  The intermediate mounting flange portion 17 is integrally provided with upper and lower support portions 21 and 22 having a circular cross section extending in opposite directions (up and down directions) on the upper and lower surfaces of the tip portion. Thereby, the upper and lower column parts 21 and 22 are arranged at the center of the back surface of the sensor light part 2. The intermediate mounting flange portion 17 functions as a column support portion that supports the upper and lower column portions 21 and 22. The upper and lower column portions 21 and 22 have such a length that a gap S exists between the front end surface thereof and the upper and lower mounting flange portions 15 and 16.

  As shown in FIGS. 2 and 4, the upper and lower support columns 21 and 22 are formed with female screw holes 21a and 22a at the center of the front end surface, and the upper and lower mounting flange portions 15 and 16 corresponding to the female screw holes 21a and 22a. The mounting holes 15b and 16b are formed through the tip of each.

  The fixture 3 includes two attachment plate members 31 whose one end portions are rotatably coupled to the support column portions 21 and 22, and are attached in a state where one is inverted with respect to the other. That is, it is a common part. The angle formed by the two mounting plate members 31 can be changed according to the shape (angle) of the mounted portion W.

  As shown in FIGS. 5A, 5B and 6, each mounting plate member 31 includes a plate-shaped mounting plate portion 31A in which mounting holes 31a and 31b to the mounted portion W are formed, and the mounting plate. It has 1st and 2nd arm parts 31B and 31C provided in the upper part or lower part of the one side edge part of part 31A, and the middle part, and was provided in the side.

  Engagement portions 31Ba and 31Ca that are rotatably engaged with the column portions 21 and 22 are formed at the tip portions of the first and second arm portions 31B and 31C. The first and second arm portions 31B and 31C are the tip end portions (engagement portions 31Ba and 31Ca) of the first and second arm portions 31B and 31C and the one side edge portion of the mounting plate portion 31A. The portions excluding the portion provided with are curved surfaces 31Bf, 31Cf, 31d, 31e.

  Further, as shown in FIGS. 7 and 8, the tip portion (engagement portion 31Ba) of the first arm portion 31B has a circular cross-section on the surface facing the second arm portion 31C. The engaging projection 31Bd is formed on the opposite surface with a concavo-convex portion 31Be that regularly extends in the radial direction, and is the tip portion of the second arm portion 31C, and the first arm portion 31B. An engagement recess 31Cd is formed on the surface opposite to the facing side so that the engagement protrusion 31Bd is rotatably engaged. Further, uneven portions 15c and 16c corresponding to the uneven portions 31Be are formed on the ends of the mounting flange portions 15 and 16 on the side facing the support columns 21 and 22. As a result, the mounting holes 15b of the mounting flange portions 15 and 16 can be rotated while the engaging portions 31Ba and 31Ca of the mounting plate member 31 are rotatably engaged with the column portions 21 and 22 in the mounting state to the mounted portion W. , 16b and the male screw 41 is applied to the female screw holes 21a, 22a via the flat washer 42 and the spring washer 43 and tightened so that the gap S is eliminated, as shown in FIG. The state where the portions 15c and 16c are separated from each other (see FIG. 9A) is changed to the state where the uneven portions 31Be and the uneven portions 15c and 16c are engaged with each other (see FIG. 9B). On the other hand, the mounting plate member 31 is fixed so as not to rotate relatively.

  Next, a procedure for attaching the sensor light 1 to a corner portion of the attached portion W, for example, at an angle of 90 degrees will be described.

  First, the two attachment plate members 31 and 31 are engaged with the engagement convex portion 31Bd in a state where the other attachment plate member 31 is reversed with respect to the one attachment plate member 31 and the positions of the slit portions 31Bb and 31Cb are matched. The recess 31 </ b> Cd is fitted and integrated as the fixture 3. Then, as shown in FIG. 6 and FIG. 7, they are spread in a single plate shape, and the column portions 21 and 22 of the sensor light portion 2 are inserted into the through-hole portions 31Bc and 31Cc through the slit portions 31Bb and 31Cb. At this time, since the mounting plate member 31 is formed of a synthetic resin material, the widths of the slit portions 31Bb and 31Cb are slightly smaller than the diameters of the column portions 21 and 22, but are spread by the resin elasticity and can be fitted without difficulty. .

  In this state, when attaching to the corner portion of the angle of 90 degrees, as shown in FIGS. 1A and 1B, the attachment plate members 31, 31 intersect so as to form 90 degrees, and each attachment plate member The attachment plate portion 31A of 31 is fixed to the attachment portion W by using attachment holes 31a and 31b using screws or the like. At this time, since the gap S is formed between the mounting flange portions 15 and 16 and the mounting plate member 31, it is easy to adjust the angle formed by the mounting plate members 31 and 31 according to the corner portion. In addition, there is no possibility that the sensor light portion 2 is detached from the fixture 3 by fitting the engagement convex portion 31Bd and the engagement concave portion 31Cd and fitting the engagement convex portion 31Bd and the support concave portions 31Cd.

  Then, after each mounting plate member 31 is mounted and fixed to the mounted portion W, the mounting angle of the sensor light unit 2 with respect to the mounting tool 3 is adjusted, and from the mounting holes 15b and 16b of the upper and lower mounting flange portions 15 and 16, It is fastened and fixed with a male screw 41 via a flat washer 42 and a spring washer 43. Thereby, the uneven part 31Be and the uneven parts 15c, 16c are engaged with each other and fixed so as not to rotate in the circumferential direction, and the positional relationship between the fixture 3 and the sensor light part 2 is fixed.

  Further, as shown in FIG. 10 (a), it can be attached to a flat wall surface, and as shown in FIGS. 10 (b) and 10 (c), a corner (an indented corner) having an angle exceeding 180 degrees. ) Can also be attached. FIG. 10C shows an attachment state when the angle is 270 degrees.

  (iii) In the above-described embodiment, the uneven portions 31Be, 15c, and 16c for fixing the mounting plate member 31 so as not to rotate relative to the support columns 21 and 22 are the uneven portions that regularly extend in the radial direction. However, it is not limited to such an uneven portion, and may be an uneven portion that generates a predetermined frictional force between the mounting plate member 31 and the upper and lower mounting flange portions 15 and 16 by tightening the male screw 41, and the shape is There is no particular limitation. Further, by reducing the gap without providing such uneven portions, a frictional force is generated and fixed between the mounting plate member 31 and the upper and lower mounting flange portions 15 and 16 by tightening the male screw 41. Is also possible.

  (iv) In the embodiment described above, the one side edge portion of the mounting plate portion 31A excluding the portion provided with the first and second arm portions 31B and 31C is the curved surfaces 31d and 31e.
