Hereinafter, embodiments will be described in detail with reference to the drawings.
Drawing 1 is an appearance perspective view showing the important section of road light 100 which is an example of the lighting fixture concerning an embodiment. The road lamp 100 is installed on a highway, for example, and illuminates the road from a relatively high place.

  The road lamp 100 has an appliance main body 10 fixed to the upper end of the column 2 in a cantilever state. That is, the instrument main body 10 has one end fixed to the upper end of the column 2 and extends in a substantially horizontal direction toward the other end. The instrument main body 10 has a substantially rectangular transparent or translucent illumination window 11 on the lower surface side thereof. A plurality of LED light sources, reflectors, lighting circuits, and the like (not shown) are accommodated in the appliance body 10. When the LED light source is turned on, illumination light is emitted through the illumination window 11.

  FIG. 2 is a perspective view showing the upper surface side of the instrument body 10. A recess 12 for attaching an adapter 3 (see FIG. 5) for fixing the upper end (not shown here) of the column 2 to the instrument body 10 is provided on the upper surface side of the instrument body 10. That is, the recess 12 is provided at a position offset toward one end side in the longitudinal direction of the instrument body 10. A mounting hole (not shown) penetrating the lower surface side of the instrument body 10 is provided at the bottom of the recess 12. The upper end of the column 2 is inserted into the recess 12 from the lower surface side of the instrument main body 10 through the attachment hole.

  The adapter 3 can be attached from the upper surface side of the instrument body 10, and is fastened and fixed in the recess 12 in an inclined posture by a plurality of screws (not shown). For this reason, if the instrument main body 10 is attached to the upper end of the column 2 via the adapter 3, the illumination window 11 becomes an obtuse angle with respect to the column 2, and the illumination light is irradiated obliquely with respect to the road surface. In addition, the upper end of the support | pillar 2 is screwed and fixed from the outer side of the adapter 3 with the several screw which is not shown in the state inserted in the adapter 3. FIG. The adapter 3 has a bottom portion that comes into contact with the upper end of the column 2, and this bottom portion engages with the upper end of the column 2.

  In addition, a power source side cable (not shown) and an LED light source side (lighting circuit side) cable (not shown) wired through the support column 2 are provided at substantially the center of the upper surface 10a of the instrument body 10. A connector unit 4 for connection is fixed by a plurality of screws 4a. The cable on the power source side is led to the connector unit 4 through a wiring hole (not shown) of the adapter 3, and the cable on the LED light source side is led to the connector unit 4 through a wiring hole (not shown) penetrating the instrument body 10. The end of each cable is connected to a predetermined terminal of the connector unit 4 by a screw (not shown).

  Furthermore, an adapter 3 (that is, the upper end of the support column 2) attached to the recess 12 and an upper surface cover 5 (opening / closing member) that covers the connector unit 4 are attached to the upper surface 10a of the instrument body 10 so as to be openable and closable. The upper surface cover 5 has a shape bulging in a dome shape, and the adapter 3 and connector slightly projecting upward from the upper surface 10a of the instrument body 10 in a state (not shown) arranged at a closed position where the upper surface 10a is closed. The unit 4 can be accommodated. The upper surface cover 5 is fastened and fixed to the upper surface 10a of the instrument body 10 by a plurality of screws (not shown) while being rotated to the closed position.

  3 and 4 are enlarged views of a connection portion in which the upper surface cover 5 is rotatably connected to the upper surface 10a of the instrument body 10. FIG. The upper surface cover 5 is movably connected to the upper surface 10a of the instrument body 10 via a hinge 6 (connection member). The hinge 6 connects the end of the upper surface cover 5 away from the column 2, that is, the end of the other end side of the instrument body 10, so as to be rotatable with respect to the upper surface 10 a of the instrument body 10. The rotation shaft 6 a of the hinge 6 extends in a direction orthogonal to the longitudinal direction of the instrument body 10.

  FIG. 5 is a side view showing a state in which the top cover 5 is opened to a predetermined angle. On the upper surface 10a of the instrument body 10, a protrusion 7 (regulating member) for abutting on the abutting surface 5a of the upper surface cover 5 to restrict the rotation in the opening direction so that the upper surface cover 5 does not open beyond a predetermined angle. Is protruding. The protrusion 7 protrudes integrally upward from the upper surface 10a on the opposite side of the hinge 6 with respect to the support column 2 (adapter 3), that is, on the other end side of the instrument body 10 from the hinge 6.

  When the top cover 5 is opened to the state shown in the figure (predetermined angle), the upper end of the protrusion 7 comes into contact with the contact surface 5a at the base end of the rotation of the top cover 5 and the top cover 5 opens in the opening direction. The rotation of is controlled. This state is shown in FIG. In the present embodiment, the protrusion height of the protrusion 7 is designed so that the upper surface cover 5 does not open 90 degrees or more with respect to the upper surface 10 a of the instrument body 10. The number and shape of the protrusions 7 can be arbitrarily set.

  In this embodiment, in order to fix one end side of the instrument main body 10 to the support column 2, a hinge 6 that rotatably connects the top cover 5 to the instrument main body 10 is provided on the other end side of the instrument main body 10. For the same reason, a protrusion 7 for restricting the rotation of the top cover 5 in the opening direction is provided on the other end side of the instrument body 10. That is, since it is difficult to secure a space for providing these structures on one end side further than the recess 12 for housing the adapter 3 for attaching the support column 2, the hinge 6 and the protrusion 7 are connected to the connector main unit 10 from the connector unit 4. Provided on the end side.

  FIG. 6 is a partially enlarged view in which a connection portion of the top cover 5 with respect to the top surface 10a of the instrument body 10 is enlarged. As described above, with the state in which the rotation of the upper surface cover 5 in the opening direction is restricted (the state shown in FIG. 5), the upper surface cover 5 can be rotated in the closing direction. As described above, when the worker performs the maintenance work while the upper surface cover 5 is rotatable in the closing direction, the upper surface cover 5 may be inadvertently closed during the work, and workability is reduced. In addition, work safety may be impaired.

  For this reason, in this embodiment, the structure for preventing the upper surface cover 5 opened to a predetermined angle from being inadvertently rotated in the closing direction is provided. That is, the road lamp 100 according to the present embodiment includes a stopper 1 (locking member) provided so as to be slidable along the upper surface 10 a of the instrument body 10. FIG. 6 shows a state where the stopper 1 prohibits the top cover 5 opened to a predetermined angle from rotating in the closing direction. In this state, the contact surface 5 a of the top cover 5 is slightly separated from the upper end of the protrusion 7.

  The stopper 1 abuts against the locking wall 5b (contact portion) of the top cover 5 that is to be closed in the closing direction from the open position at a predetermined angle in the state of being arranged at the position (first position) shown in FIG. The upper cover 5 is prohibited from rotating in the closing direction. Further, the stopper 1 is retracted to a position where it does not interfere with the upper surface cover 5 in the middle of the rotation in a state where the stopper 1 is disposed at the position (second position) shown in FIG. 3, and the upper surface cover 5 is allowed to rotate in the closing direction. . The stopper 1 is provided at a position where it can be covered by the upper surface cover 5 in a state where the stopper 1 is disposed at the position shown in FIG.

  As shown in FIGS. 3 and 4, a pair of slide rails 8 a and 8 b that slidably hold the stopper 1 along the longitudinal direction of the instrument body 10 are integrally projected on the upper surface 10 a of the instrument body 10. Yes. The two slide rails 8a and 8b extend in parallel with each other, and hold the stopper 1 between them in a slidable manner. Further, between the two slide rails 8a and 8b, a slide protrusion 9 is slidably engaged with a slide groove 1a (described later) of the stopper 1 so as to be slidable.

  The stopper 1 is formed, for example, by processing a single rectangular belt-shaped metal plate. The stopper 1 has a slide portion 1b that is sandwiched between the above-described two slide rails 8a and 8b and faces the upper surface 10a of the instrument body 10, and the slide portion 1b has the above-described slide groove 1a. Moreover, the stopper 1 has the latching | locking part 1c bent to the cross-sectional U-shape following the end of this slide part 1b.

  As shown in FIG. 3, after the upper surface cover 5 is opened to a predetermined angle, the stopper 1 is slid leftward in the figure and placed in the state shown in FIG. The five locking walls 5b face each other. The gap between the locking wall 5b of the upper surface cover 5 and the upper surface 10a of the instrument body 10 with the contact surface 5a of the upper surface cover 5 being in contact with the upper end of the protrusion 7 and the upper surface cover 5 being opened to a predetermined angle. Is slightly larger than the height from the upper surface 10 a of the instrument body 10 to the upper surface 1 d of the locking portion 1 c of the stopper 1. For this reason, when the stopper 1 is inserted into the gap, the locking wall 5b of the upper surface cover 5 is slightly separated from the upper surface 1d of the locking portion 1c of the stopper 1.

  After the stopper 1 is disposed at the position shown in FIG. 4, when the upper surface cover 5 is slightly rotated in the closing direction, the locking wall 5b of the upper surface cover 5 comes into contact with the upper surface 1d of the locking portion 1c of the stopper 1, The top cover 5 is locked in the state shown in FIG. By performing the maintenance work in this state, it is possible to reliably prevent a problem that the upper surface cover 5 is inadvertently closed during the work, improve workability, and ensure safety.

  When releasing the locked state by the stopper 1 from the state of FIG. 6, the upper surface cover 5 is slightly rotated in the opening direction, and the locking wall 5 b of the upper surface cover 5 is moved from the upper surface 1 d of the locking portion 1 c of the stopper 1. The contact surface 5 a is brought into contact with the upper end of the protrusion 7. In this state, the stopper 1 is slid from the position shown in FIG. 4 to the position shown in FIG. By moving the stopper 1 to the position of FIG. 3, the stopper 1 can be retracted from the movement path of the top cover 5, and the top cover 5 can be rotated in the closing direction.

  In the present embodiment, the width of the locking portion 1 c of the stopper 1 (the length in the direction perpendicular to the longitudinal direction of the instrument body 10) is designed to be substantially equal to the width of the locking wall 5 b of the top cover 5. However, the width of the locking portion 1c of the stopper 1 may be larger than the width of the locking wall 5b of the top cover 5. Thereby, the mechanical strength of the latching | locking part 1c of the stopper 1 can fully be raised, damage to the stopper 1 can be prevented, and the reliability of an apparatus can be improved.

Next, the installation procedure of the road light 100 described above will be described.
The column 2 of the road lamp 100 is previously installed at a predetermined position along the road, and the fixture body 10 is attached to the upper end of the column 2. In addition, the upper surface cover 5 is rotatably attached to the instrument body 10 via a hinge 6. Further, it is assumed that the adapter 3 is fastened and fixed in advance in the recess 12 of the instrument body 10.

  First, the worker lifts the instrument main body 10 provided with the adapter 3 to the upper end of the column 2 and fits the upper end of the column 2 to the adapter 3. At this time, prior to the work, the worker opens the top cover 5 and slides the stopper 1 to the position shown in FIG. 4 to fix the top cover 5 in the open position. In this state, the worker inserts a plurality of screws from the outside of the adapter 3, and fastens and fixes the adapter 3 to the upper end of the column 2. Thereby, the instrument main body 10 is fixed to the upper end of the column 2.

  Thereafter, the worker fixes the cable routed through the column 2 to the connector unit 4, and fixes the cable on the instrument body 10 side to the connector unit 4. Then, the worker slides the stopper 1 from the position of FIG. 4 to the position of FIG. 3, closes the upper surface cover 5 to the upper surface 10 a of the instrument body 10, and covers the upper end of the column 2 together with the connector unit 4. Finally, the worker fastens and fixes the upper surface cover 5 to the upper surface 10a of the instrument body 10 using a plurality of screws.

  As described above, according to the present embodiment, when the appliance main body 10 of the road lamp 100 is attached to the upper end of the support column 2, the top cover 5 can be reliably fixed at the open position, so that workability can be improved. Safety can be increased. Even when the instrument body 10 is removed from the support column 2 for maintenance of the instrument body 10, the upper surface cover 5 can be fixed in the open position, and workability and safety can be improved.

  In addition, according to the present embodiment, since the upper surface cover 5 is fixed at the open position, a simple configuration is provided in which the stopper 1 is simply slid, so that the device configuration can be simplified and the manufacturing cost of the device can be reduced. Further, according to the present embodiment, the top cover 5 can be securely fixed at the open position by simply sliding the stopper 1 between two positions, and the work burden on the worker can be reduced. 100 installation costs can be reduced.

  FIG. 7 is a side view showing a modification of the mechanism for fixing the top cover 5 to the open position. Here, the same reference numerals are given to components that function in the same manner as in the above-described embodiment, and detailed description thereof will be omitted.

  In this modification, a stopper 1 ′ is used in which the length of the locking portion 1 c in the longitudinal direction is longer than that in the embodiment described above. That is, the stopper 1 ′ has a function of restricting the upper surface cover 5 opened at a predetermined angle from rotating in the opening direction and a function of prohibiting the upper surface cover 5 from rotating in the closing direction from the open position. .

  When the stopper 1 ′ is slid to the position shown in FIG. 7, the contact surface 5a ′ of the upper cover 5 faces the upper surface 1d of the locking portion 1c, and at the same time, the engagement of the upper cover 5 with the upper surface 1d of the locking portion 1c. The stop wall 5b faces. The protruding height of the contact surface 5a ′ is such that when the locking portion 1c of the stopper 1 ′ is inserted into the gap between the upper surface cover 5 ′ opened to the open position and the upper surface 10a of the instrument body 10, the locking portion 1c. It is designed so that a slight gap is formed between the upper surface 1d of the upper surface and the upper surface cover 5 '.

  When the upper surface cover 5 tries to rotate in the opening direction from the state shown in FIG. 7, the contact surface 5 a ′ contacts the upper surface 1 d of the locking portion 1 c of the stopper 1, and the upper surface cover 5 rotates in the opening direction. To regulate. Further, in this state, when the upper surface cover 5 tries to rotate in the closing direction, the locking wall 5b comes into contact with the upper surface 1d of the locking portion 1c of the stopper 1, and the upper surface cover 5 is prohibited from rotating in the closing direction. Control.

  According to the above modification, the top cover 5 ′ opened to the open position can be fixed by one stopper 1 ′, and the rotation in the opening direction and the closing direction can be prevented at the same time. It can be omitted, and the apparatus configuration can be simplified accordingly.

  The above-described embodiments are presented as examples and are not intended to limit the scope of the invention. The above-described embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
