  The luminaire described in Patent Document 1 employs a structure in which a socket cover is slid by pressing a button for unlocking the socket cover when replacing the lamp. In this structure, the release button can be confirmed at a glance. Therefore, if a lighting fixture adopting this structure is installed on a ceiling or the like having a height of about 2 m in a place where an unspecified number of people are present, such as a railway vehicle, the lock can be easily released. There is a risk that the person will remove the lamp.

  In the luminaire described in Patent Literature 2, a structure is adopted in which the socket cover is pinched and deformed, the engagement protrusion of the socket cover is removed from the engagement recess of the cover base, and the socket cover is slid. In the operation of pinching the socket cover by hand, a gripping force can be easily applied. Therefore, since the socket cover can be easily slid even with this structure, the lamp may be removed by an unintended third party.

  For example, an object of the present invention is to prevent a socket cover that covers a socket for a lamp from being easily removed.

The socket cover mounting mechanism according to one aspect of the present invention is:
A socket cover mounting mechanism for mounting a socket cover for covering a socket for a lamp by sliding the socket cover on a socket cover base provided around the socket,
A guide groove is formed inside the socket cover,
A claw is formed at the tip of the protruding piece protruding from the surface to which the socket cover of the socket cover base is attached,
With the claw entering the guide groove, the socket cover slides to a position covering the socket.

  In the present invention, the socket cover covers the socket in a state where the claw formed at the tip of the protruding piece protruding from the surface of the socket cover base where the socket cover is attached enters the guide groove formed inside the socket cover. The structure that slides to the position is adopted. For this reason, the socket cover cannot be easily removed.

  As shown in FIGS. 5 and 6, the socket cover base 15 includes a base plate 41, two slide guide portions 42, and two protruding pieces 43. The base plate 41 is formed with an insertion hole 44 into which the socket 13 is inserted. The two slide guide portions 42 are erected from the base plate 41 in parallel with each other so as to sandwich the insertion hole 44. An engagement recess 45 corresponding to the engagement protrusion 35 of the socket cover 14 is formed on one end side of each slide guide portion 42. The two projecting pieces 43 project (stand up) from the surface of the base plate 41 to which the socket cover 14 is attached, in the vicinity of the other end side (the side opposite to the engaging recess 45) of the slide guide portion 42. A claw 46 is formed at the tip of each protruding piece 43. The claw 46 is tapered. Between the two protruding pieces 43, a mounting sounding recess 47 corresponding to the mounting sounding protrusion 34 of the socket cover 14 is formed.

  Below, the procedure (Socket cover attachment method concerning this Embodiment) which attaches the socket cover 14 to the socket cover base 15 is demonstrated.

  First, after the straight tube lamp 20 is attached to the socket 13, the inner surface of the slide guide portion 42 of the socket cover base 15 and the outer surface of the slide piece 32 of the socket cover 14 are brought into contact with each other. The socket cover 14 is fitted into the socket cover base 15.

  When the socket cover 14 is fitted into the socket cover base 15, the claw 46 at the tip of the protruding piece 43 of the socket cover base 15 enters the guide groove 33 of the socket cover 14. In this state, the cover body 31 of the socket cover 14 is slid so that the outer surface of the slide piece 32 of the socket cover 14 slides along the inner surface of the slide guide portion 42 of the socket cover base 15. Close. That is, the cover body 31 is slid to a position where the cover body 31 of the socket cover 14 covers the socket 13 with the claw 46 entering the guide groove 33. At this time, the mounting sounding projection 34 of the socket cover 14 is fitted into the mounting sounding recess 47 of the socket cover base 15 and a sound is produced. At the same time, the engaging projection 35 of the socket cover 14 fits into the engaging recess 45 of the socket cover base 15. In other words, in a state where the cover body 31 of the socket cover 14 has reached the position covering the socket 13, the mounting sounding projection 34 fits into the mounting sounding recess 47 and the engaging projection 35 fits into the engagement recess 45.

  As described above, in the present embodiment, the socket cover 14 can be easily attached to the instrument body 11 simply by being inserted into the socket cover base 15.

  In this embodiment, the claw 46 of the socket cover base 15 is inserted into the guide groove 33 of the socket cover 14 so that the claw 46 moves along the guide groove 33, and the claw 46 is detached from the socket cover 14. It has two effects: prevention and sliding guide of the socket cover 14. That is, according to the present embodiment, it is possible to prevent the socket cover 14 from being easily removed by vibrations or unintended operations, and the socket cover 14 can be easily attached.

  In the present embodiment, since the claw 46 is tapered, the claw 46 can easily enter the guide groove 33. Therefore, the attachment of the socket cover 14 becomes even easier.

  In the present embodiment, when the socket cover 14 is closed, the mounting sound projecting portion 34 fits into the mounting sound generating recess portion 47, and at that time a sound such as “click” sounds. It can be confirmed that it is attached to the cover base 15. Further, since a feeling of moderation (clicking feeling) is generated when the mounting sounding projection 34 is fitted into the mounting sounding recess 47, it can be confirmed that the socket cover 14 is closed by touch.

  The wearing sound projecting convex portion 34 is an example of a projecting portion, and the mounting sound producing recess portion 47 is an example of a recessed portion. The same effect as described above can be obtained by changing the mounting sounding convex part 34 to a concave part and changing the mounting sounding concave part 47 to a convex part. That is, it is possible to easily confirm that the mounting of the socket cover 14 is completed by generating a sound when the convex portion is fitted into the concave portion.

  In the present embodiment, when the socket cover 14 is closed, the engagement convex portion 35 fits into the engagement concave portion 45, so that the end portion on the opening side of the socket cover 14 can be prevented from sliding down. Therefore, even if a malfunction occurs in the claw 46 and the claw 46 is easily detached from the guide groove 33, the socket cover 14 can be prevented from falling off by fitting the engagement convex portion 35 and the engagement concave portion 45. .

  Moreover, the engagement convex part 35 is an example of a convex part, and the engagement recessed part 45 is an example of a recessed part. Even if the engaging convex portion 35 is changed to a concave portion and the engaging concave portion 45 is changed to a convex portion, the same effect as described above can be obtained. That is, by fitting the convex portion into the concave portion, the convex portion is prevented from coming off in a direction perpendicular to the surface of the socket cover base 15 to which the socket cover 14 is attached. When the lighting fixture 10 is installed on the ceiling of a railway vehicle or the like, the socket cover 14 can be prevented from falling off.
