The outdoor lighting fixture 10 which is 1st Embodiment of this invention is the main body case 12 which comprises one side of the fixture main body 11, the cover 13 which comprises the other of the fixture main body 11, the lamp | ramp 14 accommodated in the cover 13, and a main body. The street lamp includes a lens 15 fixed at a position corresponding to the lamp 14 of the case 12, a hollow illumination column 16 fixed to the main body case 13, a string-like body 17, and a rod-like body 18.

  As shown in FIG. 1, the main body case 12 is formed in a semi-egg shape using, for example, aluminum die casting which is a molding material. The surface of the main body case 12 is painted to prevent corrosion.

  The main body case 12 has an illumination column fixing hole 19 at the end of the illumination column, and the end of the illumination column is connected to the end of the cover 13 on the illumination column 16 side via a hinge member 20. ing.

  The main body case 12 includes a latch member 21 at the end on the side opposite to the illumination column 16. The latch member 21 is locked to the main body case 12 by being hooked on the cover 13 when the cover 13 is closed with respect to the main body case 12 via the hinge member 20.

  The main body case 12 has a string-like body binding portion 22 that is a fixed portion at a substantially central portion of the lower surface thereof. The string-like body binding portion 22 is formed so as to protrude into a cylindrical boss shape.

  The lens 15 is made of a transparent or translucent resin and is attached to the lower surface of the main body case 12.

  The cover 13 is formed in a shape that covers the half egg shape of the main body case 12. The surface of the cover 13 is painted to prevent corrosion. The cover 13 includes a socket 23, and the lamp 14 is attached to the socket 23. The socket 23 is electrically connected to an instrument wiring (not shown). The appliance wiring is electrically connected to an external lighting circuit through the inside of the lighting column 16.

  A reflector 24 for reflecting the light from the lamp 14 toward the ground is formed around the socket 23.

  As shown in FIG. 2, the illumination column 16 is a hollow column having a uniform inner diameter. The illuminating column 16 has a base end portion buried in the ground, and has a distal end portion opened.

  The string-like body 17 is a wire member that can withstand a large load such as a wire rope and has a relatively small wire diameter. The string-like body 17 has a corrosion resistance sufficiently longer than the time when corrosion or metal fatigue occurs in the main body case 12 and the cover 13 forming the instrument main body 11.

  One end portion 25 of the string-like body 17 is bound to the string-like body binding portion 22 of the main body case 12 by a washer 26 and a screw 27. The length of the string-like body 17 is set to a value sufficiently shorter than the value obtained by subtracting the length dimension of the instrument body 11 from the length dimension from the opening at the tip of the illumination column 16 to the ground.

  The string-like body 17 is inserted into the illumination column fixing hole 19 of the main body case 12, and the rod-like body 18 is bound to the other end portion 28.

  As shown in FIG. 3, the rod-like body 18 is formed in a rod shape using a steel material such as a steel material for machine structure. The rod-like body 18 has an annular string-like body binding ring portion 29 at the upper end thereof, and a support shaft portion 30 below the string-like body binding wheel portion 29.

  When the support shaft portion 30 is disposed obliquely at the opening of the illumination column 16, the upper end thereof is engaged with the opening of the illumination column 16 and the lower end thereof is engaged with the inner surface of the illumination column 16. The illumination column 16 has a sufficiently long length L1 in the axial direction. At this time, the support shaft 30 is held in the opening of the lighting column 16 by tilting the opening of the lighting column 16 at an inclination angle θ1 of about 45 degrees with respect to the axial direction of the lighting column 16 (see FIG. 6). It has become so.

The string-like body 17 is rotatably connected to the rod-like body 18 by being bound to the string-like body binding ring portion 29.
As a result, when the string-shaped body 17 and the rod-shaped body 18 are twisted, the string-shaped body 17 and the rod-shaped body 18 are rotatably connected to each other, so that a shear stress accompanying the twist is applied to the string-shaped body. There is nothing.
Therefore, the string-like body 17 is not cut by twisting.

  As shown in FIG. 4, the main body case 12 is formed with three through-holes 31 arranged in the axial direction of the illuminating column 16 at the edge on the illuminating column 16 side. The three through holes 31 are formed through the illumination column fixing hole 19. The illumination column 16 has a screw hole 32 corresponding to the through hole 31.

  When the main body case 12 is attached to the illumination column 16, the illumination column fixing hole 19 is extrapolated to the illumination column 16 and the three through holes 31 are aligned with the screw holes 32 of the illumination column 16. The main body case 12 is fixed to the lighting column 16 by a nut 33 disposed in the lighting column 16, a bolt 34 screwed into the nut 33, a bolt 35 screwed into the screw hole 32, and a washer 36.

  As shown in FIG. 5, the outdoor lighting fixture 10 is installed by burying the base end part of the illumination pillar 16 in the ground, and the fixture main body 11 is arranged at a high place.

  During this normal use, the string-like body 17 in which the one end portion 25 is bound to the string-like body binding portion 22 of the main body case 12 accommodates the other end portion 28 in the illumination column 16 together with the rod-like body 18.

  As shown in FIG. 6, when corrosion or metal fatigue has occurred in the main body case 12 of the instrument main body 11 due to long-term use, the main body case 12 in the instrument main body 11 with a relatively large load becomes the load of the entire instrument main body 11. Unbearable.

  If the illumination column fixing hole 19 of the main body case 12 is detached from the illumination column 16 by any chance, the string-like body 17 is dropped together with the instrument body 11 and pulled out from the opening of the illumination column 16. Go.

  As the string-like body 17 is pulled out, the rod-like body 18 rises in the illumination column 16. When the string-like body binding ring portion 29 of the rod-shaped body 18 reaches the opening of the illumination column 16, the rod-shaped body 18 is disposed obliquely and the upper end portion of the shaft support portion 30 is engaged with the opening of the illumination column 16. Combine.

Then, the rod-shaped body 18 is tilted at an inclination angle θ1 of about 45 degrees with respect to the axial direction of the illumination column 16 inside the illumination column 16 and its lower end is engaged with the inner surface of the illumination column 16 to form a rod shape. The body 18 does not move, and the withdrawal of the string-like body 17 is stopped.
In addition, when the length of the string-like body 17 is set to, for example, the length from the rod-like body 18 when the rod-like body 18 is caught in the opening of the illumination column 16 to a position where the instrument body 11 does not collide with a person, The main body 11 does not collide with a person.

  Thereby, the string-like body 17 hangs and holds the instrument main body 11 to prevent the instrument main body 11 from falling.

  As shown in FIG. 7, in the 1st modification of the rod-shaped body 18 applied to the outdoor lighting fixture 10 of 1st Embodiment which concerns on this invention, the upper end part and lower end part of the support shaft part 30 are made from an elastic body. A buffer member 37 was attached. The buffer member 37 buffers an impact force when contacting the inner surface of the illumination column 16.

In the rod-shaped body 18 of the first modified example, when the rod-shaped body 18 comes into contact with the inner surface of the illumination column 16, the shock is not applied to the string-shaped body 17 by the buffer member 37.
Therefore, the string-like body 17 is not cut by an impact or the like.

  As shown in FIG. 8, in the 2nd modification of the rod-shaped body 18 applied to the outdoor lighting fixture 10 of 1st Embodiment which concerns on this invention, a string-shaped body binding part is carried out in the center part of the comparatively long support shaft part 30. As shown in FIG. 38 was formed.

  In the rod-shaped body 18 of the second modified example, since the support shaft portion 30 has the same top and bottom structure with the string-like body binding portion 38 as the center, the insertion direction to the illumination column 16 can be made from any direction, and workability can be improved. Improvements can be made.

  As shown in FIG. 9, in the third modification of the rod-shaped body 18 applied to the outdoor lighting fixture 10 of the first embodiment according to the present invention, the retaining plate member 39 is not attached to the other end portion 28 of the string-shaped body 17. And the pipe member 40 having a predetermined length (corresponding to the length dimension L1) was assembled by accommodating the string-like body 17 above the retaining plate member 39.

  In the rod-shaped body 18 of the third modified example, since the rod-shaped body 18 can be manufactured simply by inserting the pipe member 40 through the string-shaped body 17 at the construction site, the man-hour can be drastically reduced.

In the outdoor lighting fixture 10 of the first embodiment, the rod-like body 18 bound to the other end portion 28 of the string-like body 17 is accommodated in the lighting column 16, and the one end portion 25 of the string-like body 17 is tied to the string-like shape of the main body case 12. The instrument body 11 bound to the body binding portion 22 is fixed to the illumination column 16. When the instrument body 11 is detached from the illumination column 16 due to corrosion or metal fatigue, the string-like body 17 is pulled out from the illumination column 16 together with the instrument body 11. However, as the string-like body 17 is pulled out, the rod-like body 18 is hooked and held at the front end of the illumination column 16 by the opening of the illumination column 16 and the inner surface below the opening, and the string-like body 17 is pulled out. Stopped.
Thereby, it is not necessary to fix another member to the illumination column like the conventional one.
Accordingly, it is possible to improve the productivity by reducing the number of parts, and at the same time, it is possible to drastically improve the workability at the time of manufacture and construction and to prevent the fall.

In the outdoor lighting device 10 according to the first embodiment, when the string-shaped body 17 and the rod-shaped body 18 are twisted, the string-shaped body 17 and the rod-shaped body 18 are bound together in a freely rotatable manner. Shear stress is not applied to the string-like body 17.
Therefore, since the string-like body 17 is not cut by twisting, the quality can be improved.

In the outdoor lighting fixture 10 of 1st Embodiment, when the rod-shaped body 18 contacts the inner surface of the illumination pillar 16, the shock at that time is not given to a string-shaped body by the buffer member 37.
Therefore, since the string-like body 17 is not cut by an impact or the like, the quality can be improved.
