The operation of these coil springs 35 will be described later.

  FIG. 6 shows the front shape of the fixture 5, and the description will be continued with reference to FIG. 6. As shown in FIG. 6, the attachment device 5 has a substantially square surface 50, and four side surfaces 51 are formed around the surface 50. As will be described later, the side surface 51 can also be configured to be a position defining portion that defines the mounting position of the housing 10.

  The portion including the surface 50 is made of, for example, a synthetic resin, and four projecting member passage holes 52 are formed therein. Each of these projecting member passage holes 52 extends from the surface 50 toward the inside of the attachment device 5, and the tip thereof is connected to an engagement hole 53 extending in the direction of arrow A. The cross-sectional shape in the plane parallel to the surface 50 of each overhang member passage hole 52 is a rectangular shape that is long in the vertical direction, and the overhang member 24 inserted into the overhang member 24 together with the engaging portion 25 is described later. It is allowed to move in the direction of arrow A and in the opposite direction. In this embodiment, the overhang member passage hole 52 and the engagement hole 53 constitute a member passage hole in the present invention.

  Further, when the luminaire 1 is attached to the attachment device 5, the surface 50 is prevented from rattling in the attachment direction, that is, the direction in which the distance from the attachment device 5 changes. Four columnar protrusions 54 for facilitating the work of removing the bracket from the mounting device 5 are formed. The operation of the projection 54 will be described in detail later.

  Moreover, when the lighting fixture 1 is attached to the attachment fixture 5 from the bottom surface 11 side, the driving current power supply terminal 57 and the current receiving terminals 17 and 19 formed on the bottom surface 11 are in contact with the surface 50. 59 and signal current feed terminals 58 and 60 which are in contact with the power receiving terminals 18 and 20 respectively. The power supply terminals 57, 58, 59 and 60 are urged outward, that is, in front of FIG. 6, by a biasing means such as a spring (not shown) to ensure contact with the power receiving terminal. Yes.

  Of the four overhanging member passage holes 52, the peripheral portions of the two overhanging member passage holes 52 on the upper side in FIG. 6 are substantially T-shaped and are convex portions 61 slightly raised from the surface 50. 62, and the peripheral portions of the two projecting member passage holes 52 on the lower side in FIG. 6 are convex portions 63 and 64 that are formed in a vertically long rectangular shape and slightly raised from the surface 50. As will be described later, these convex portions 61 to 64 act as position defining portions that define the position in the vertical direction of the housing 10 (that is, the linear direction including the arrow A direction).

  Further, on the surface 50, connectors 70 and 71 to which wiring for receiving a drive current from the outside is connected, connectors 72 and 73 to which wiring for receiving a signal current from the outside is connected, and the mounting device 5 are provided on a wall surface or the like. The attachment holes 74 to 77 for attachment, the string attachment portion 78 to which the other end of a lighting fixture fall prevention string (not shown) whose one end is fixed to the housing 10 side, and the vertical attachment direction of the attachment instrument 5 are shown. Indications 79 and 80, a wiring passage hole 81 for passing the above-described wiring, and the like are provided. Furthermore, a circuit board (not shown) for the drive current and the signal current is accommodated in the mounting fixture 5.

  Hereinafter, an operation of attaching the lighting fixture 1 to the mounting fixture 5 will be described. FIG. 1 shows a state after the lighting device 1 is attached to the attachment device 5, and FIG. 5 shows an enlarged peripheral portion of the overhang member 24 under this state. 5 shows the overhanging member 24 passing through the long hole 11a on the side surface 12 side of the housing 10, and the following description will be made on this portion. The same applies to the overhanging member 24 passing therethrough.

  In the lighting fixture 1 before the state shown in FIGS. 1 and 5, that is, the lighting fixture 1 removed from the mounting fixture 5, the two slide members 22 are urged by the compression coil springs 26, thereby It is in the foremost position (the uppermost position in the figure). The foremost position is defined by the front end surface 24a of the overhang member 24 shown in FIG. 5 coming into contact with the inner wall (upper wall surface in the drawing) of the long hole 11a. Instead of this, the foremost position of the slide member 22 may be defined by the upper end of the slide member 22 shown in FIG.

  In the lighting device 1 in the above state, first, the square frame 16 of the housing 10 surrounds the four side surfaces 51 of the mounting device 5, for example, by holding both side surfaces 12 and 13 with both hands of the operator. It is set to the position where When the lighting fixture 1 is pushed into the mounting fixture 5 as it is, the inclined end surface 25b of the engaging portion 25 at the tip of the overhanging member 24 becomes the inner wall 52a of the overhanging member passage hole 52 (in the drawing). The engagement portion 25 and the overhanging member 24 move downward against the urging force of the compression coil spring 26 by being pressed against the outer edge portion of the upper wall surface). As a result, the engaging portion 25 gets over the inner wall of the overhanging member passage hole 52 and moves upward, that is, in the direction of the arrow A by the urging force of the compression coil spring 26. As shown in FIG. Get in. Thus, when the four engaging portions 25 are respectively engaged with the engaging holes 53, the inner surface 25a of the engaging portion 25 is engaged even if an external force in a direction away from the mounting device 5 acts on the lighting device 1. Since it abuts against the inner wall 53a of the joint hole 53, the luminaire 1 is prevented from being detached from the mounting fixture 5. The inner wall 53a is a surface that engages with the engaging portion 24 after moving in the arrow A direction and prevents the engaging portion 24 from moving to the surface 50 side.

  When the lighting fixture 1 is attached to the mounting fixture 5 in this way, if the relative positions of the two are correct, the convex portions 61 and 62 of the mounting fixture 5 are substantially T-shaped formed on the housing 10 of the lighting fixture 1. The concave portions 41 and 42 are combined with each other, and the convex portions 63 and 64 are combined with rectangular concave portions 43 and 44 which are also formed in the housing 10. If the lighting fixture 1 is to be attached to the mounting fixture 5 in an incorrect direction, the above-described combination is not performed, and it is impossible to push the housing 10 to a predetermined position. Is prevented from being attached. And when the convex portions 61, 62, 63 and 64 are combined with the concave portions 41, 42, 43 and 44, respectively, the housing 10 of the lighting fixture 1 cannot move in the vertical direction (the linear direction including the arrow A direction). The vertical position of the housing 10 is defined.

  When the lighting fixture 1 is attached to the mounting fixture 5 in the correct orientation, the four protrusions 54 of the mounting fixture 5 enter the round holes 34 of the housing 10 of the lighting fixture 1 and are disposed in the round holes 34. The coil spring 35 is compressed. Therefore, the housing 10 is pushed away from the attachment device 5 and is held at a position where the inner surface 25 a of the engagement portion 25 abuts against the inner wall 53 a of the engagement hole 53. Thereby, it is prevented that the lighting fixture 1 rattles in the mounting direction, that is, the direction in which the distance from the mounting fixture 5 changes.

  The four protrusions 54 define the vertical position of the casing 10 together with the convex portions 61 to 64, particularly when the outer diameter is set to a value that is slightly smaller than the inner diameter of the round hole 34. It also acts as a position defining part. In this case, the overhang member 24 and the engaging portion 25 of the lighting fixture 1 basically serve to prevent the lighting fixture 1 from dropping off.

  When the lighting fixture 1 is attached to the mounting fixture 5 in the correct orientation, the power receiving terminals 17 and 19 formed on the bottom surface 11 of the housing 10 come into contact with the drive current power supply terminals 57 and 59 of the mounting fixture 5 respectively. Similarly, the power receiving terminals 18 and 20 formed on the bottom surface 11 come into contact with the signal current power supply terminals 58 and 60 of the fixture 5, respectively, so that power can be supplied from the fixture 5 to the lighting fixture 1. As described above, since the power feeding terminals 57, 58, 59 and 60 are urged outward, the contact with the power receiving terminals 17, 18, 19 and 20 is ensured, respectively.

  When removing the luminaire 1 from the fixture 5, for example, while holding the both side surfaces 12 and 13 with both hands of the operator, the two operation portions 23 are moved downward by the thumb of each hand, that is, in the direction opposite to the arrow A direction. Is moved to. As a result, the two slide members 22 are moved downward, and the four engaging portions 25 are respectively pulled out downward from the engaging holes 53. Therefore, if the lighting fixture 1 is pulled away from the mounting fixture 5 as it is, the lighting fixture 1 is removed. be able to.

  In this embodiment, when the lighting fixture 1 is attached to the mounting fixture 5, the casing 10 is pushed away from the mounting fixture 5 by the action of the coil spring 35 compressed as described above. . Therefore, when the engagement between the engagement portion 25 and the engagement hole 53 is released as described above, the housing 10 is elastically separated from the attachment device 5 and the bottom surface 11 of the housing 10 and the attachment device 5 are separated. A slight gap is formed between the surface 50 and the surface. Therefore, the lighting device 1 can be easily removed from the mounting device 5 by inserting a fingertip into the gap.

  When attaching the lighting fixture 1 to the mounting fixture 5, the operator moves the two operation portions 23 downward as described above, and then pushes the lighting fixture 1 toward the mounting fixture 5, thereby The operation unit 23 may be released when the bottom surface 11 of the ten reaches a predetermined position in contact with the surface 50 of the fixture 5. If such an operation is indispensable, the end surface 25b of the engaging portion 25 may not be particularly inclined.

  As described above, the operation unit 23 may be arranged inside the housing 10 so as not to be exposed from the housing 10. In that case, the front portion of the housing 10 is made detachable from the housing main body, and when the luminaire 1 is attached or detached, the front portion or the like is removed from the housing main body and operated in that state. The unit 23 may be operated. Even in this case, if the end face 25b of the engaging portion 25 is an inclined surface, the operation portion 23 need not be operated when the lighting fixture 1 is attached. You don't have to remove it from

  Further, as shown in FIG. 7, the engaging portion 25 may be formed in a state parallel to the bottom surface 11 and facing in the lateral direction with respect to the arrow A direction. In this case, as shown in FIG. 8, the attachment device 5 has an L-shaped opening on the surface 50 and extends to the inside of the attachment device 5, and an engagement hole 153 having an inner wall 153a. What is necessary is just to provide the member passage hole which consists of. The inner wall 153a is a surface that engages with the engaging portion 24 after moving in the arrow A direction and prevents the engaging portion 24 from moving toward the surface 50 side.

  In the present embodiment, the dimensions are set so that there is a slight gap between the side surface 51 and the frame body 16; however, if the dimensions are set so that they are closely combined, the illumination The mounting position of the fixture 1 in the vertical direction (linear direction including the direction of arrow A) and the direction orthogonal thereto is defined by the four side surfaces 51 of the fixture 5 coming into contact with the frame 16 of the lighting fixture 1 from the inside. Is also possible. That is, in such a case, the side surface 51 also functions as a position defining portion that defines the vertical mounting position of the housing 10.

  Moreover, when forming them so that there may be a slight gap between the side surface 51 and the frame body 16, it is possible to define the vertical mounting position of the luminaire 1 using the overhanging member 24. . That is, in that case, the front end surface 24a of the overhanging member 24 presses the inner wall 52a of the overhanging member passage hole 52 of the mounting device 5, and the inner surface 16a of the upper side portion of the frame 16 and the mounting device 5 So as to be in contact with the side surface 51 of the upper side portion. By doing so, the lighting fixture 1 has a shape in which a part of the mounting fixture 5 is sandwiched from above and below by the upper side portion of the frame 16 and the overhanging member 24, and its vertical mounting position is defined. That is, in this case, the upper side portion of the frame body 16 and the side surface 51 of the portion in contact with the frame body 16 constitute a movement blocking mechanism that blocks the lighting device 1 from moving in the direction opposite to the arrow A direction with respect to the mounting device 5. It will be.

  In this case, the upper side portion of the frame 16 constitutes the holding member in the present invention, the inner surface 16a serves as a contact surface, and the front end surface 24a of the projecting member 24 serves as the pressing surface and the projecting member passage hole 52. The inner wall 52a becomes a pressed surface.

  Note that when the vertical mounting position of the lighting fixture 1 is defined as described above, the lower side portion of the frame body 16 may be omitted. Furthermore, when the attached lighting fixture 1 is difficult to move in the left-right direction, or when there is no problem even if it moves slightly in the left-right direction, the right side portion and the left side portion of the frame 16 may be omitted. Furthermore, the member which prescribes | installs the attachment position of the lighting fixture 1 may be comprised from a short convex part etc. other than said frame 16.

  Further, as shown in FIG. 9, the movement preventing mechanism that prevents the lighting fixture 1 from moving in the direction opposite to the arrow A direction with respect to the mounting fixture 5 includes a convex portion 90 formed on the mounting fixture 5 side, and the lighting fixture. It can also be configured with the lower side surface 33 of one casing 10.

  Moreover, in the above embodiment, it is made to attach to the attachment fixture 5 in the state which the lighting fixture 1 stood up, However, The lighting fixture 1 is used in the horizontal state, using the mechanism as demonstrated above as it is.
