The lid stopper 100 for a lighting fixture according to the embodiment of the present invention includes a fixture main body 510 having a rectangular shape in plan view, which is formed like a main body of a lunch box, with side surfaces raised from the four sides of the bottom portion, and this fixture. And a lid 520 made of a glass plate that closes the main body 510. The instrument body 510 and the lid body 520 are hinged so as to be pivotable by a hinge 530 so that the instrument body 510 can be opened and closed. A packing 540 made of silicon rubber or the like is disposed inside the flange portion of the opening peripheral edge of the main body 510.
In addition to the light source, the instrument body 510 incorporates a reflection plate for efficiently guiding light from the light source to the outside. For this reason, the internal space of the instrument main body 510 is limited.
The lid 520 and the instrument main body 510 are kept closed by a locking member (not shown).
The casing configured in this manner is attached in a state where the instrument main body 510 is in contact with the peripheral wall at a high position of the tunnel.

  As shown in FIGS. 7 and 8, the guide member 110 constituting the lighting device lid stopper 100 is formed by bending two opposite sides of a substantially square stainless steel plate at right angles. The bent portion is the wall portion 111, and the base portion 112 is in between. Therefore, the wall portion 111 is connected to the base portion 112.

The wall 111 is provided with a guide groove 113 having a substantially L shape with a short horizontal axis. A sliding groove portion 113 </ b> A (corresponding to an L-shaped vertical axis) occupying most of the guide groove 113 is formed in parallel to the wall portion 111. The guide groove 113 is set to have a width dimension that allows a sliding engagement portion 150 described later to slide smoothly.
A lock groove 113B (corresponding to an L-shaped horizontal axis), which is one end of the slide groove 113A, is bent in a direction perpendicular to the open side of the wall 111 from the slide groove 113A. In addition, the lock groove 113B is set to a size that allows at least a sliding engagement portion 150 (to be described later) to be completely fitted.

  The base portion 112 has two base portion side through holes 114 through which bolts 610 for attaching the guide member 110 to the instrument body 510 pass. As shown in FIG. 7, the base part side through-hole 114 may be opened on a straight line connecting the lock grooves 113B of the guide grooves 113 of the two wall parts 111. As shown in FIG. In some cases, it is established on a straight line connecting the start ends (corresponding to the uppermost position of the L-shaped vertical axis) of the sliding groove 113A of the guide groove 113 of the two wall portions 111. Of course, it may be formed in the middle.

  On the other hand, as shown in FIGS. 7 and 9, the support member 120 attached to the lid 520 is configured to bend at a right angle with the two short sides of the rectangular stainless steel plate as the ears 121. . The ear 121 has an opening 123 for supporting an arm member 130 described later. Further, two support member side through holes 124 through which bolts 620 for attaching the support member 120 to the lid 520 pass are formed in the substrate portion 122 which is a portion in contact with the lid 520.

Further, as shown in FIG. 10, the arm member 130 is formed in a substantially arc shape, and both ends of the arc-shaped portion 131 are substantially circular land portions 132A and 132B. Arm through holes 134A and 134B are formed in the centers of the land portions 132A and 132B, respectively.
The arm member 130 is pivotally supported on the support member 120 by using one arm through hole 134B, the opening 123 of the support member 120, and the bolt / nut 140.
Two arm members 130 are used for one lighting fixture lid stopper 100.

The arm member 130 is attached in a state in which the arm member 130 can slide in the guide groove 113 by the other arm through hole 134A, the guide groove 113 of the guide member 110, and the sliding engagement portion 150 formed of a bolt and a nut. It is the shaft portion of the bolt that fits into the guide groove 113. Therefore, the shaft portion of the bolt is slightly smaller than the thickness dimension of the guide groove 113, and the head portion of the bolt is set larger than the thickness dimension of the guide groove 113.
The arm member 130 is attached to the guide member 110 or the like so that the concave side faces the inner surface side of the side surface of the instrument body 510.

The guide member 110 of the lighting device lid stopper 100 configured as described above is fixed to the inside of the side surface of the fixture body 510 by using a bolt 610 and a nut that is screwed to the bolt 610, and the support member 120 is provided inside the lid 520. A bolt 620 and a nut screwed to the bolt 620 are fixed to the side surface.
Moreover, the lighting device lid stopper 100 is attached to the same position as the hinge 530 that hinges the fixture body 510 and the lid 520.

The lighting fixture lid stopper 100 thus attached to the housing operates as follows.
As shown in FIG. 1, the lid 520 is at a position perpendicular to the side surface of the instrument body 510 and closes the instrument body 510. And the glass plate which comprises the cover body 520 is contacting the packing 540 inside the opening peripheral part of the instrument main body 510. FIG.
In this state, the sliding engagement portions 150 of the two arm members 130 are located at the start end of the sliding groove 113A.

The locked state between the lid body 520 and the instrument body 510 is released, and the lid body 520 is moved in the opening direction.
Then, as shown in FIG. 2, according to the movement of the lid 520, the sliding engagement portion 150 of the arm member 130 moves the sliding groove 113A toward the lock groove 113B. In this state, the arm member 130 is not in contact with the packing 540.

  When the lid body 520 is further moved and the state shown in FIG. 3, that is, immediately before the lid body 520 is in the open state, the sliding engagement portion 150 is positioned at the end portion of the sliding groove 113A. In this state, the sliding engagement portion 150 is in the sliding groove portion 113A and has not yet been fitted into the lock groove portion 113B.

Then, the arm member 130 contacts the packing 540. Then, due to the elastic force of the packing 540, the sliding engagement portion 150 is fitted into the lock groove portion 113B as shown in FIG. In this state, the lid body 520 is completely opened, and is not closed even if the hand is released from the lid body 520. This is because the sliding engagement part 150 is fitted and locked in the lock groove 113B.
Note that even if the lid 520 is displaced for some reason and the arm member 130 is displaced as a result, the arm member 130 is surely in contact with the packing 540, so that a reliable operation is guaranteed.
In this state, the arm member 130 is not in contact with the packing 540. This is because the arm member 130 moves in a direction away from the packing 540 by fitting the sliding engagement portion 150 into the lock groove portion 113B.

In order to release this state, that is, to close the lid 520, it is necessary to move the two arm members 130 toward the packing 540 at the same time. This is because the two arm members 130 are pushed up to the packing 540 side with fingers or the like to simultaneously disengage the two sliding engagement portions 150 from the lock groove 113B.
When the two arm members 130 are pushed up toward the packing 540 and the two sliding engagement portions 150 are separated from the lock groove portions 113B and enter the sliding groove portions 113A, the lid body 520 is moved in the closing direction. To be able to.

  If the force in the closing direction is forcibly applied to the lid 520 without pushing up the arm member 130 toward the packing 540, the force is applied in the direction in which the sliding engagement portion 150 is fitted by the lock groove 113B. Therefore, the open state of the lid 520 is not released. In particular, if the force is excessive, the arm member 130 is bent into a square shape as shown in FIG. When the lid 520 is a glass plate, it may be damaged by an excessive force. However, since the arm member 130 is deformed before the glass plate is damaged, the glass plate can be prevented from being damaged.

  Further, even if a force in the opening direction is further applied to the lid body 520 in the open state, the arm member 130 is pressed against the packing 540 and the sliding engagement portion 150 is further pressed against the lock groove portion 113B. The engagement between the sliding engagement portion 150 and the lock groove portion 113B is not released. Therefore, even if a force in the opening direction is applied to the lid body 520 in the open state, the lid body 520 does not close.

For example, when the lid 520 is open for maintenance, the lid 520 may be inadvertently closed because the arm member 130 is pressed against the packing 540 even if the operator's helmet or the like hits the lid 520. Therefore, the lid body 520 does not close against the operator's will during maintenance, so safety is high.
Particularly, in the case of the lighting device lid stopper 100 using the above-described two arm members 130, the sliding engagement portion 150 of one arm member 130 out of the two arm members 130 is locked. If the remaining one arm member 130 maintains the engaged state even if it is detached from the groove 113B, the lid 520 will not be closed unexpectedly, so that the safety is high.

  By forcibly applying a force in the opening direction to the lid 520 in the open state, the arm member 130 is strongly pressed against the packing 130, the arm member 130 is bent, and the glass plate is damaged in advance. Can be prevented.

  Furthermore, since the lid stopper 100 for lighting equipment is set so that the arm member 130 does not exceed the size of the guide member 110, including when the lid 520 is opened and closed, a light source, a reflector, etc. Can be stored inside the instrument body 510 with a limited space.

Since the above-described lighting device lid stopper 100 is provided with the two arm members 130, the lid body 520 is provided at the center of the lid body 520, so that the lid body 520 in the open state can be stably provided at two locations. Can be supported.
However, considering higher stability, it is desirable to provide a plurality of lighting device lid stoppers 100 in one housing. It would be desirable to provide it at the same location as the hinge 530.

  In the above-described embodiment, two arm members 130 are used for one lighting fixture lid stopper 100. However, one arm member 130 or three or more arm members 130 may be used.

  Further, the lighting device lid stopper 100 is not limited to the tunnel lighting device housing, but is provided with a lid that is hinged to the device body and pivoted to be opened and closed. Needless to say, the present invention can be applied to any lighting fixtures.
