As shown in FIG. 2, two hinges 20, 20 as rotating couplings are disposed on the base end portion 4 </ b> A of the lamp body 4, and the lid 1 is connected to the lamp body via these hinges 20, 20. 4 is pivotally supported so that it can be opened by rotating upward. Even if the hinges 20 and 20 are detached or damaged, the lid body 1 is immediately dropped or drooped by adopting a configuration in which the lid body 1 is pivoted upward with respect to the lamp body 4 and opened. There is nothing to do.
When performing operations such as lamp replacement and maintenance inspection, the lid body 1 is opened upward so that the lid body 1 does not get in the way when the lid body 1 is opened. In addition, a lid support device 50 that holds the lid 1 in an open state with respect to the lamp body 4 is provided in the lamp body 4, and the specific configuration of the lid support device 50 will be described in detail later. Describe.

As shown in FIGS. 1 and 2, a locking mechanism 40 that firmly locks the lid 1 is provided at the distal end 4 </ b> B of the lamp body 2 </ b> A of the lighting fixture 2 in order to securely hold the closed state of the lid 1. ing. The locking mechanism includes an inner latch device 30 that locks the lid body 1 by a latch, and an outer latch device 31 that is provided so as to cover the inner latch device 30 and locks the lid body 1 by a latch. The lamp body 4 and the lid body 1 are double latched by the inner latch device 30 and the outer latch device 31, and the lid body 1 is firmly locked.
As a result, even if a relatively strong force is applied to open the lid body 1 by wind and rain or vibration, the lid body 1 is prevented from being opened even if the lighting fixture 2 is installed at a relatively high place on the side of the road. .

A main body side partition wall 6 is provided inside the lamp body 4, and the main body side partition wall 6 partitions the interior into a component storage portion 7 on the base end portion 4 </ b> A side and a lamp storage portion 9 on the distal end portion 4 </ b> B side. ing.
As shown in FIG. 3, the component storage unit 7 has a column fixing unit 10 as a fixing means for the column 3 and a terminal block 13 disposed adjacent to the column fixing unit 10 at the center thereof. It is stored. As shown in FIG. 2, the lamp housing portion 9 includes a socket mounting base 14 </ b> A, a socket 14 attached to the socket mounting base 14 </ b> A and electrically connected to the terminal base 13, and a lamp attached to the socket 14. 5, and the above-described light projection opening 15 is formed on the lower surface of the lamp housing 9.

  As shown in FIG. 3, the column fixing unit 10 fixes the column receiving unit 11 that receives the upper end of the column 3 inserted from the lower side of the lamp body 4, and the column receiving unit 11 and the upper end of the column 3. A fixing bolt 12 as a fixing member to be fixed, and the fixing bolt 12 is screwed into a bolt hole (not shown) drilled in the upper end portion of the column 3 to fix the lamp body 4 to the column 3. And the rotation stop of the lamp body 4 about the column 3 is performed.

  The lamp 5 shown in FIG. 2 has a columnar shape having a long axis, and is attached to the socket 14 in a posture that extends from the base end portion 4A side to the tip end portion 4B side (the column 3 to the road side) in the lamp storage portion 9. Thus, a substantially symmetrical light distribution can be realized along the traffic direction of the road with the luminaire 2 as the center. As this lamp 5, for example, a mercury lamp, a high-pressure sodium lamp or the like is used. In particular, by using a high-pressure sodium lamp, power saving can be realized as compared with a mercury lamp, and running costs can be reduced and resources can be effectively used.

Further, as shown in FIG. 2, a lid body side partition wall 21 is provided inside the lid body 1, and the lid body side partition wall 21 corresponds to the component storage portion 7 and the lamp storage portion 9 of the lamp body 4. The interior is partitioned into a component storage portion covering portion 22 on the base end portion 4A side and a reflecting mirror storage portion 24 on the distal end portion 4B side.
The component storage portion cover portion 22 functions as a cover member that covers the component storage portion 7 of the lamp body 4, and the reflection mirror 27 is stored in the reflection mirror storage portion 24.
In the component storage cover portion 22, when the lid 1 is closed, the upper edge portions 29 on both sides of the component storage portion 7 enter the inside of the component storage portion cover portion 22 in close contact with each other. Prevention of intrusion of wind and rain and foreign matter into the storage unit 7 is achieved.
Further, the reflecting mirror housing portion 24 is provided with a packing 24A along the edge. When the lid body 1 is closed, the contact portion between the reflecting mirror housing portion 24 and the lamp housing portion 9 is formed by the packing 24A. Sealed to prevent the entry of wind and rain and foreign objects.

The reflecting mirror 27 is made of a material having a high reflectivity with respect to the radiated light of the lamp 5 (for example, aluminum) in a substantially dome shape, and the inner surface has irregularities corresponding to the light distribution to be realized. Is formed.
The reflecting mirror 27 is located on the lamp body 4 side in a state where the lid 1 is closed, and is formed to have a size enough to cover the periphery of the lamp 5 accommodated in the lamp body 4 from above. A U-shaped notch 28 for avoiding the socket 14 provided in the lamp body 4 is formed on the base end 4A side.
Further, the reflecting mirror 27 is configured so that the edge portion 27A comes close to the lower surface of the lamp body 4 when the lid 1 is closed, and leaks light from the gap between the reflecting mirror 27 and the lamp body 4. In this way, most of the radiated light of the lamp 5 can be taken out from a light projecting opening 15 formed on the lower surface of the lamp body 4.

  When the lid 1 is in the closed state, the main body side partition wall 6 that partitions the interior of the lamp body 4 and the lid body side partition wall 21 that partitions the interior of the lid body 1 come into contact with each other. The lamp housing part 9 and the parts housing part 7 of the lamp body 4 are completely separated by the lid side partition wall 21. As described above, by separating the lamp storage unit 9 and the component storage unit 7, for example, smoke or the like that has entered the component storage unit 7 from the gap between the column 3 and the column fixing unit 10 enters the lamp storage unit 9. This prevents a decrease in efficiency due to contamination of the translucent plate 16 and the reflecting mirror 27.

Next, the configuration of the above-described lid support device 50 that holds the lid 1 in an open state will be described in detail.
As shown in FIG. 2, the lid support device 50 is disposed on the left side of the lamp body 2A. When the lid 1 is closed, the lid support device 50 is folded and made compact as shown in FIG. It is stored in the component storage unit 7 in a state.

4 to 6 are enlarged views of the lid support device 50. FIG. 4 is a perspective view showing the open state, FIG. 5 is a side view showing the open state, and FIG. 6 shows the closed state. It is a side view.
As shown in these drawings, the lid support device 50 includes a bendable link mechanism 54 for connecting the lamp body 4 and the lid 1, and a link mechanism when the lid 1 is opened with respect to the lamp body 4. And a stopper mechanism 70 that restricts the folding of the lid 54 and holds the lid 1 incapable of being closed.

  Specifically, one end 54A of the link mechanism 54 is fixed to the inside of the lamp body 4, and the other end 54B is fixed to the inside of the lid 1. As shown in FIGS. With the opening and closing of 1, the transition is made between a linear state and a bent state. In the opened state, the link mechanism 54 is linear, and the stopper mechanism 70 restricts the bending of the link mechanism 54, whereby the link mechanism 54 is held linearly. Thus, the link mechanism 54 held in a straight line functions as a so-called grip bar, and the lid 1 is held against the lamp body 4 so as not to be closed.

When the restriction of the link mechanism 54 by the stopper mechanism 70 is released, the link mechanism 54 can be folded and closed, and when the lid 1 is completely closed, as shown in FIG. It is stored in the component storage unit 7 in a state of being folded into a substantially V shape and becoming compact.
As described above, since the lid support means included in the lid support device 50 is configured to use the link mechanism 54 that can be bent as the lid 1 is opened and closed, the link mechanism 54 is provided when the lid 1 is closed. It can be stored in a folded and compact state, saving space.

In the present embodiment, as shown in FIGS. 2 and 3, the link mechanism 54 is configured such that one end 54 </ b> A on the side connected to the lamp body 4 is disposed on the base end 4 </ b> A side in the lamp body 4. Yes. More precisely, as shown in FIG. 3, the one end 54 </ b> A of the link mechanism 54 is in the base end portion of the component storage portion 7 of the lamp main body 4 than the column fixing portion 10 stored in the component storage portion 7. It is connected to the position avoided on the 4A side.
With such a configuration, when the lid 1 is opened, the link mechanism 54 moves from the position deviating to the base end portion 4A side from the column fixing portion 10 to the lid 1 as shown in FIG. Therefore, the link mechanism 54 does not interfere with the extension of the hand into the component storage portion 7 of the lamp body 4.

  In particular, in this embodiment, as shown in FIGS. 2 and 3, the fixing bolt 12 for fixing the column receiving portion 11 of the column fixing portion 10 to the column 3 is connected to the link mechanism 54 (lid support device 50). Although provided on the same side, one end 54 </ b> A of the link mechanism 54 is connected to a position avoiding the base end 4 </ b> A side with respect to the column fixing part 10, so that the link mechanism 54 obstructs the operation of the fixing bolt 12. Thus, the fixing bolt 12 can be operated safely and steadily.

Next, the link mechanism 54 and the stopper mechanism 70 included in the lid support device 50 will be described in more detail.
The link mechanism 54 includes a lamp-side fixed link 51 whose one end 51 </ b> A is screwed and fixed to the lamp body 4, and a lid-side fixed link 52 whose one end 52 </ b> A is screwed and fixed to the lid 1 via the mounting base 53. A lamp-side movable link 56 having one end 56A rotatably supported by a support pin 55 on the other end 51B of the lamp-side fixed link 51, and one end on the other end 52B of the lid-side fixed link 52. 58A is rotatably supported by a support pin 57, and the other end portion 58B has a lid side movable link 58 that is rotatably supported by a support pin 59 on the other end portion 56B of the lamp side movable link 56. It is configured. The lamp-side movable link 56 and the lid-side movable link 58 rotate about the support pin 59 so that they can be bent (bent) as described above. The lamp-side fixing link 51 may be formed integrally with the lamp body 4 to further increase the strength. Similarly, the lid-side fixing link 52 is formed integrally with the lid 1 to increase the strength. It is good also as a structure which raises more.

As shown in FIG. 6, in the closed state, the link mechanism 54 has the lamp-side movable link 56 and the lid-side movable link 58 bent in a substantially V shape with the support pin 59 as a valley, as described above. Are stored in the component storage portion 7 of the lamp body 2A in a compact state.
When the lid 1 is opened upward (arrow A in FIG. 6) from this closed state, the lid-side fixed link 52 fixed to the lid 1 is pulled upward, and in conjunction with this, the lid-side movable link 58 and the lamp-side movable link 56 connected to the lid-side movable link 58 are pulled up. At this time, the lamp-side movable link 56 rotates with respect to the lamp-side fixed link 51 in the same direction (arrow C in FIG. 6) as the rotation direction of the lid 1 (arrow B in FIG. 6) with the support pin 55 as the center. By moving, as shown in FIG. 5, the connecting part (bent part) of the lamp-side movable link 56 and the lid-side movable link 58 is pulled upward, and the lid 1 is further opened, so that The lamp-side movable link 56 and the lid-side movable link 58 are extended in a substantially linear shape (bar shape).

  The structure of the connecting portion of the lamp-side movable link 56 and the lid-side movable link 58 will be described in further detail. As shown in FIGS. 4 to 6, the other end 56B of the lamp-side movable link 56 and the lid-side movable link 58 are connected. In each of the other end portions 58B, elongated holes 61 and 62 are formed extending along the longitudinal direction of the lamp-side movable link 56 and the lid-side movable link 58 (indicated by the arrow X in FIG. 4). The lamp-side movable link 56 and the lid-side movable link 58 are rotatably connected by the support pin 59 passing through both the long holes 61 and 62, and further, as shown in FIG. The pin 59 moves along the long holes 61 and 62, and the lamp-side movable link 56 and the lid-side movable link 58 are configured to be extendable and contractable in the longitudinal direction.

  The stopper mechanism 70 operates so as to restrict the rotation of the lid-side movable link 58 in the closing direction when the lamp-side movable link 56 and the lid-side movable link 58 rotate and become linear. The bending of the link mechanism 54 is restricted by holding the lamp-side movable link 56 and the lid-side movable link 58 linearly. Thereby, the link mechanism 54 functions as a gripping rod, and the lid 1 is held by the link mechanism 54 so as not to be closed.

The configuration of the stopper mechanism 70 will be described in detail. As shown in FIGS. 4 and 5, the stopper mechanism 70 is provided at the other end portion 56 </ b> B of the lamp-side movable link 56, and the lid-side movable link 58 supports the support pin 59. It has a stopper plate 71 that restricts rotation in the direction of closing the lid at the center (arrow D in FIGS. 4 and 5).
As shown in FIG. 4, the stopper plate 71 is formed by bending a bent piece formed on the other end portion 45 </ b> B of the lamp-side movable link 56, and the lid-side movable link 58 is movable on the lamp side by the long hole 62. As the entire length of the lid side movable link 58 and the lamp side movable link 56 is reduced, the stopper plate 71 is moved to the link 56 side, so that the stopper plate 71 has an edge 58C of the other end 58B of the lid side movable link 58. Thus, the rotation of the lid-side movable link 58 in the closing direction is restricted, and the lid-side movable link 58 and the lamp-side movable link 56 are maintained in a substantially linear shape.
On the contrary, the lid side movable link 58 moves in the direction away from the lamp side movable link 56 along the long hole 62, so that the other end portion 58 </ b> B of the lid side movable link 58 and the stopper plate 71 are engaged. Is released, and the lid-side movable link 58 and the lamp-side movable link 56 can be bent at the connecting portions around the support pin 59.

Under the above configuration, the lid support device 50 operates as shown in (A) to (G) as the lid 1 is opened and closed as shown in FIG.
That is, as the lid body 1 is opened upward from the closed state ((G) of FIG. 7), the link mechanism 54 in the folded state has one end 54B on the side connected to the lid body 1 at the lid body 1. At the same time, it is pulled upward ((E) and (F) in FIG. 7) and becomes linear ((C) in FIG. 7).

When the lid 1 is continuously opened, the lid side movable link 58 and the lamp side movable link 56 are extended ((B) in FIG. 7). When the lid 1 is extended to the maximum, the link mechanism 54 opens the lid further. It is regulated ((A) in FIG. 7: maximum open state).
Further, when the lid-side movable link 58 is moved to the lamp-side movable link 56 when the lid-side movable link 58 and the lamp-side movable link 56 are linear, as described above, the other end of the lid-side movable link 58 is moved. The state in which the lid-side movable link 58 and the lamp-side movable link 56 are in a substantially linear shape is held in contact with the edge 58C of the portion 58B, whereby the lid body 1 is held by the link mechanism 54 so that it cannot be closed. (D in FIG. 7: locked state).

  When the locked state is released and the lid body 1 is closed, the lid body side movable link 58 is separated from the lamp side movable link 56 by opening the lid body 1 or the like, and the other end portion 58B of the lid body side movable link 58 and the stopper are separated. The engagement with the plate 71 is released ((C) in FIG. 7). As a result, the lid-side movable link 58 and the lamp-side movable link 56 can be bent at the connecting portion around the support pin 59, for example, by pulling the stopper plate 71 forward (toward the distal end portion 4B side). The movable link 56 and the lid-side movable link 58 are folded around the support pin 59 ((E), (F), (G) in FIG. 7), so that when the lid 1 is completely closed, the lid is supported. The device 50 is housed in the lamp body 4 in a state where the link mechanism 54 is compactly folded ((G) in FIG. 7: closed state).

Here, for example, the lamp-side movable link 56 and the lid-side movable link 58 of the link mechanism 54 extend, as in the maximum open state of FIG. In the state in which the engagement between the stopper plate 71 and the stopper plate 71 is released, there is nothing that regulates the rotation of the lid-side movable link 58 and the lamp-side movable link 56. The lid 1 will be closed without permission.
Therefore, in the lid support device 50 of the present embodiment, the lid side movable link 58 is moved to the lamp side movable link 56 side in conjunction with the lid closing operation of the lid body 1 as shown in FIGS. A guide piece 80 is provided for the purpose.

More specifically, as shown in FIG. 5, the guide piece 80 is provided at the end 58A of the lid-side movable link 58 on the lid-side fixed link 52 side, and when the lid 1 rotates in the closing direction, When the lower edge 52C of the lid-side fixed link 52 that moves integrally with the lid 1 comes into contact with the guide piece 80, and the lid 1 is rotated in the closing direction, the lid-side movable link 58 becomes the lamp-side movable link. It is pressed to the 56 side. As a result, the other end portion 58B of the lid body side movable link 58 is engaged with the stopper plate 71, and the lid body 1 is automatically locked so that it cannot be closed.
Therefore, when the lid 1 is opened to some extent and the lid-side movable link 58 and the lamp-side movable link 56 are linear, even if the lid 1 is released in a state where the lid 1 is not sufficiently locked, Since the lid body 1 is automatically locked so as not to be closed with the movement of the lid body 1, the lid body 1 is not unexpectedly closed.

Further, the lamp-side movable link 56 is formed with a long hole 63 along the longitudinal direction at the connecting portion with the lamp-side fixed link 51, and the support pin 55 moves along the long hole 63. The lamp side movable link 56 is configured to be extendable and contractable with respect to the lamp side fixed link 51.
As a result, the distance between the ends 54A and 54B of the link mechanism 54 is variable, and as shown in FIG. 7A, the maximum open state in which the lid 1 is opened to the maximum, and FIG. As shown in FIG. 5, the opening degree θ of the lid 1 can be made different between the locked state in which the lid 1 is locked so as not to be closed.

At this time, by adjusting the length of the long hole 63 of the lamp-side movable link 56, that is, the amount of expansion / contraction of the lamp-side movable link 56 with respect to the lamp-side fixed link 51, for example, as shown in FIG. In the maximum open state, the opening degree θ can be an obtuse angle (90 degrees or more), and as shown in FIG. 7D, the opening degree θ can be an acute angle (90 degrees or less) in the locked state.
In particular, by setting the opening angle θ in the locked state to an acute angle, there is a building wall or the like behind the lighting fixture 2 (base end portion 4A side), and the lid 1 is greatly opened by being obstructed by the wall or the like. Even if this is not possible, the opened lid 1 can be reliably locked.

As described above, according to the present embodiment, the lid body 1 is supported by the lid body support device 50 including the foldable link mechanism 54 in an open state, and therefore the lid body 1 is closed. In this case, the link mechanism 54 can be housed in the lamp body 4 in a compactly folded state, and the space can be used effectively.
Further, since one end 54A of the link mechanism 54 is connected to the base end 4A side of the lamp body 4, the link mechanism 54 is opened from the base end 4A side of the lamp body 4 to the lid 1 when the lid 1 is opened. The link mechanism 54 does not get in the way when reaching into the lamp body 4.

  In particular, according to the present embodiment, since the one end 54A of the link mechanism 54 is connected to a position avoiding the base end portion 4A side with respect to the column fixing portion 10, the link mechanism 54 obstructs the operation of the fixing bolt 12. Thus, the fixing bolt 12 can be operated safely and steadily.

Further, according to the present embodiment, the lamp-side movable link 56 and the lid-side movable link 58 of the link mechanism 54 are connected to each other by the support pins 59 so as to be movable and movable, and the lamp-side movable link 56 is interlocked with the opening. When the end side 58B of the lid side movable link 58 moves to the lamp side movable link 56 side, the stopper plate 71 of the stopper mechanism 70 is engaged with the end side 58B. Thus, the rotation of the lid-side movable link 58 is restricted, and the lamp-side movable link 56 and the lid-side movable link 58 are held in a substantially linear shape.
As a result, the stopper mechanism 70 automatically engages with the lid-side movable link 58 in conjunction with the opening of the lid and restricts the rotation, so that the opening can be performed only with the engagement structure without using a separate device such as a gas spring. The stopper mechanism 70 can be operated in conjunction with the lid to support the lid 1.

  Further, according to the present embodiment, the lid support device 50 includes the guide piece 80 that is pressed by the lid-side fixed link 52 in conjunction with the closure and moves the lid-side movable link 58 to the lid-side movable link 56 side. If the lid 1 is opened to some extent and the lid-side movable link 58 and the lamp-side movable link 56 are linear, the lid 1 can be opened even if the lid 1 is released without being fully locked. Since the lid 1 is automatically locked so as not to be closed with the movement of the body 1, the lid 1 is not unexpectedly closed.

  Further, according to the present embodiment, the lamp-side movable link 56 is connected to the lamp-side fixed link 51 by the support pin 55 so as to be extendable and contractable, and the opening degree θ of the lid 1 in the locked state is set to the lamp-side movable link 56. Adjustable by the amount of expansion and contraction. As a result, the opening degree θ in the locked state can be adjusted to an acute angle, and there is a building wall or the like behind the lighting fixture 2 (on the base end portion 4A side). Even when the opening cannot be greatly opened, the opened lid 1 can be reliably locked.

  In addition, embodiment mentioned above shows the one aspect | mode of this invention to the last, and a deformation | transformation and application are arbitrarily possible within the scope of the present invention.

  For example, in the above-described embodiment, the lighting fixture 2 in which the distal end portion of the support column 3 is inserted and fixed from the lower side is shown. However, the present invention is not limited to this, and as shown in FIGS. The present invention can also be applied to the luminaire 100 having a configuration in which the distal end portion of the support column 3 is inserted and supported from the rear surface side. 8 and 9, the members described in the above embodiment are given the same reference numerals.

In this luminaire 100, as shown in FIG. 8, the distal end portion of the column 3 extending substantially horizontally from the outer wall 200 of a building or the like is inserted from the base end portion 4A side of the lamp body 4, and as shown in FIG. In addition, the lamp body 4 is fixed to a column fixing portion 170 disposed substantially at the center of the component storage portion 7 of the lamp body 4.
This column fixing part 170 is configured to include a column receiving part 150 that receives the column 3 so as to cover the tip of the column 3 and a fixing bolt 160 that fixes the column receiving part 150 to the column 3.
Also in such a lighting fixture 100, the link mechanism 54 is fixed by connecting one end 54 </ b> A of the link mechanism 54 included in the lid support device 50 to a position avoiding the base end 4 </ b> A side with respect to the column fixing part 170. There is no obstacle to the operation of the bolt 160.

Here, as shown in FIG. 8, if the support column 3 is short and the outer wall 200 and the lighting fixture 100 are close to each other, the outer wall 200 may be in the way and the lid 1 may not be opened widely.
