Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view illustrating a configuration of a lighting fixture 1 according to the present embodiment.
The lighting apparatus 1 is an apparatus that can be installed outdoors and used as, for example, road lighting. As shown in the figure, the lighting fixture 1 includes a fixture main body 10 that is supported by the tip 2A of a column 2 that is erected outdoors such as a roadside, a streetside, a parking lot, or a park. Installed. The column 2 shown in the figure is a so-called arm type in which a tip end portion 2A of a column erected on the ground or the like is bent substantially horizontally in an L shape. The instrument body 10 has a substantially rectangular shape in plan view, and a rear end 10A viewed from a road or the like to be irradiated is attached to and supported by the column 2.

FIG. 2 is a perspective view showing an internal configuration on the rear end 10 </ b> A side of the instrument body 10. FIG. 3 is a cross-sectional view of the rear end 10 </ b> A side of the instrument body 10. FIG. 4 is an exploded view of the rear end 10 </ b> A side of the instrument body 10.
As shown in these drawings, a clamp chamber 21 for accommodating the clamp 5 is provided inside the instrument body 10 on the rear end 10A side. The clamp 5 is a support member that supports the instrument body 10 in a state of being attached to the column 2. In the present embodiment, the clamp 5 is fixed by four screws 30 (FIG. 5) from the outside of the instrument body 10 in a state where the clamp 5 is housed in the clamp chamber 21.

The clamp 5 of the present embodiment includes a cylindrical tube portion 50 and a pair of fixed pieces 52.
The cylindrical portion 50 is a member into which the distal end portion 2A of the support column 2 is inserted. As shown in FIG. 4, a cylindrical portion insertion hole 60 formed by a knockout hole is provided at the rear end 10 </ b> A of the instrument body 10. An end portion 50A of the cylindrical portion 50 is inserted into the cylindrical portion insertion hole 60 from the inside of the clamp chamber 21, protrudes to the outer side of the instrument body 10, and the distal end portion 2A of the column 2 is inserted from the end portion 50A.
A plurality of bolt holes 54 are formed on the outer peripheral surface of the cylindrical portion 50, and the distal end portion 2 </ b> A of the support column 2 and the cylindrical portion 50 are fastened by bolts inserted into the respective bolt holes 54.

  Further, on the outer peripheral surface of the cylindrical portion 50, a ridge 55 extending along the central axis direction of the cylindrical portion 50 is formed. By providing the ridge 55, the strength for bolt mounting can be increased. On the other hand, the cylindrical portion insertion hole 60 is provided with a recess 57 for receiving the protrusion 55. The posture (direction) of the cylindrical portion 50 around the central axis is defined by the engagement of the ridges 55 and the concave portions 57 in addition to the screws 30.

  The fixing piece 52 is a part for fixing the clamp 5 to the instrument body 10 by bolting to the instrument body 10. The fixing pieces 52 are provided on both sides of the cylinder portion 50. As shown in FIG. 4, the clamp chamber 21 is formed with a pair of engagement surfaces 58 extending from the rear end surface 63 to the bottom surface 65. The fixed piece 52 is engaged with these engaging surfaces 58.

  A plurality of screw holes 59 are formed in the fixed piece 52, and a long hole 61 is formed in the engagement surface 58. The long hole 61 extends over each screw hole 59 of the fixed piece 52, and each of the screw holes 59 is exposed to the outside of the instrument body 10 by the long hole 61. Thereby, even if the clamp chamber 21 is not opened, a screw is inserted into each of the screw holes 59 from the outside of the instrument body 10 through the long hole 61 to fasten the fixing piece 52 and the engaging surface 58, and loosen the fastening. it can.

  In the present embodiment, the fixed piece 52 slides on the engagement surface 58, and the mounting angle of the instrument body 10 is varied by this sliding movement.

More specifically, each of the fixed piece 52 and the engagement surface 58 has an arc shape in side view as shown in FIG. The arc drawn by the fixed piece 52 and the engagement surface 58 is a part of the circle 68 of a predetermined radius centered on the rotation center O set in the instrument body 10 on the rear end 10A side of the instrument body 10. It is. The rotation center O is the rotation center when adjusting the mounting angle.
As the fixed piece 52 slides along the arc of the circle 68 of the engagement surface 58, the instrument body 10 rotates about the rotation center O. By this rotation, the mounting angle (inclination angle) of the instrument body 10 with respect to the axial direction of the distal end portion 2A of the column 2 can be varied, and the angle can be adjusted.

In the lighting fixture 1 of this embodiment, the mesh structure is formed in the surface where the fixing piece 52 and the engagement surface 58 contact each other.
Specifically, as shown in FIG. 4, the fixing piece 52 is formed with a clamp-side concavo-convex portion 70 in the arc-shaped surface that contacts the engagement surface 58. On the other hand, a main body side uneven portion 72 is formed on the engagement surface 58 in the arc-shaped surface that contacts the fixed piece 52.

  The clamp side uneven portion 70 and the main body side uneven portion 72 mesh with each other, thereby forming an interlocking structure. And in adjustment of the attachment angle of the instrument main body 10, it becomes adjustable by changing the meshing position with the clamp side uneven | corrugated | grooved part 70 and the main body side uneven | corrugated | grooved part 72. FIG.

In the present embodiment, the clamp-side uneven portion 70 and the main body-side uneven portion 72 have different lengths in the arc range (that is, the slide movement range). Specifically, the length of the main body side uneven portion 72 of the engaging surface 58 where the long hole 61 is formed is shorter than the clamp side uneven portion 70 of the fixing piece 52 where the screw hole 59 is formed. Yes.
With this configuration, the tool body 10 can be easily cast and the cost can be reduced. That is, when trying to provide a relatively long concave and convex portion inside the instrument body 10, in the casting of the instrument body 10, a portion that requires an undercut treatment occurs, and it is necessary to create a mold that slides inward. Manufacturing cost will be high. On the other hand, even if the clamp 5 is cast, if a relatively long uneven portion is provided, a sliding mold is required, but the cost is less than that of forming a long uneven portion inside the instrument body 10.

  Here, in addition to the arm type, a pole type is known as the support 2. As shown in FIG. 5, in the pole-type column 102, the tip end portion 102 </ b> A of the column 102 is inserted and supported at the bottom of the lighting fixture 1. In the lighting fixture 1 of this embodiment, the lighting fixture 1 can be attached to the pole-type support | pillar 102 using the same clamp 5 as the case of an arm type.

  That is, as shown in FIG. 3, an arc drawn by the fixing piece 52 and the engaging surface 58, that is, a place where the fixing piece 52 slides is formed in a convex shape toward the outside of the rear end 10 </ b> A of the instrument body 10. ing. With this configuration, as shown in FIG. 6, the clamp 5 is erected so that the central axis of the cylindrical portion 50 faces the vertical direction and the end portion 50 </ b> A for receiving the tip end portion 102 </ b> A of the support column 102 is positioned downward. Even when the hole 54 is directed to the inside of the clamp chamber 21, as shown in FIG. 7, the fixing piece 52 of the clamp 5 can be engaged with the engaging surface 58 on the side of the instrument body 10. . Further, this makes it possible to slide the fixed piece 52 along the engagement surface 58 and change the mounting angle of the instrument body 10.

Thus, according to the present embodiment, the following effects can be obtained.
That is, in the lighting fixture 1 of the present embodiment, an engagement surface 58 that extends from the rear end surface 63 to the bottom surface 65 of the fixture body 10 and on which the fixed piece 52 of the clamp 5 slides is provided in the fixture body 10. It has been. The fixing piece 52 and the engagement surface 58 are part of an arc shape of a circle 68 centering on the rotation center O when the mounting angle of the instrument body 10 is adjusted, and are convex to the outside of the instrument body 10. is there.
As a result, the clamp 5 is rotated by 90 degrees, and the fixed piece 52 of the clamp 5 is engaged with the engagement surface 58, so that it can be attached to either the arm-type support column 2 or the pole-type support column 102. It is possible to adjust the mounting angle of the instrument body 10.

Moreover, in the lighting fixture 1 of this embodiment, the fixing piece 52 of the clamp 5 is screwed from the outside of the fixture body 10.
Thereby, even if it does not open the clamp chamber 21 of the instrument main body 10, the clamp 5 can be slid and the attachment angle of the instrument main body 10 can be easily adjusted only by loosening a screw. In addition, since the clamp 5 is provided inside the instrument body 10, the clamp 5 does not fall off from the instrument body 10 even if the screw is removed.

Further, in the lighting fixture 1 of the present embodiment, the fixing piece 52 of the clamp 5 is provided with a plurality of screw holes 59 for screwing, and the engagement surface 58 of the fixture body 10 is provided with the plurality of screw holes 59. A long hole 61 is provided to extend over. Further, on the contact surfaces of the fixed piece 52 and the engagement surface 58, a clamp side uneven portion 70 and a main body side uneven portion 72 that mesh with each other are provided. And the main body side uneven part 72 is shorter than the clamp side uneven part 70 in the length of the slide movement direction of the region where the uneven part is formed.
With this configuration, the tool body 10 can be easily cast and the cost can be reduced.

  The above-described embodiment is merely an example of one aspect of the present invention, and can be arbitrarily modified and applied within the scope of the gist of the present invention.

For example, as shown in FIG. 8, the engagement surface 58 may extend to an arc shape (that is, a semicircular arc shape) having a central angle of approximately 180 degrees. As a result, by simply rotating the clamp 5 by 90 degrees, both the arm-type support column 2 and the pole-type support column 102 can be attached so that the angle can be adjusted using the same clamp 5.
Instead of the engagement surface 58, the clamp-side uneven portion 70 may extend to an arc shape (that is, a semicircular arc shape) having a central angle of approximately 180 degrees.

  Moreover, although it was set as the structure which clamps the clamp 5 from the outer side in the lighting fixture 1, you may screw from the inner side of the fixture main body 10 not only in this. In this case, a plurality of screw holes 59 for screwing may be provided in the engaging surface 58 instead of the fixed piece 52, and the long hole 61 may be provided in the fixed piece 52. Further, when the elongated hole 61 is provided in the fixed piece 52, the length of the region in the slide transition direction of the clamp side uneven portion 70 is shorter than that of the main body side uneven portion 72.

  The present invention is applicable to any lighting fixture attached to the support columns 2 and 102.
