  An embedded mounting device according to an embodiment of the present invention will be described with reference to the drawings. The elements constituting the implantable attachment device in the figure are determined in terms of dimensions and shapes for convenience of explanation, and the implantable attachment device is not limited to the illustrated form.

  1 to 3 show a support 5, a slider 7, a spring 9, a swing arm 11, a connecting rod 13, and a trigger 15 that constitute the operating unit 3 of the implantable attachment device 1. FIG. 1 shows an example in which the support 5 is inserted into the opening 19 formed in the ceiling plate 17 from below. 2 and 3 show the elements of the operation unit 3 provided inside each of the three supports 5 shown in FIG. 1 in two drawings. The drawings refer to FIGS. 1 to 3 unless otherwise specified.

  An edge member 21 that is hooked around the periphery of the opening 19 of the ceiling plate 17 is joined to the lower ends of the three supports 5. Each support 5 is obtained by joining a circular plate 27 having an insertion hole 25 to the upper end of a bent steel plate having a side opening 23. For example, the socket 29 inserted through the insertion hole 25 can be fixed to the disk 27, and a lighting fixture 31 such as a light bulb can be attached to the socket 29. Furthermore, each support body 5 protrudes support pieces 33, 35, 37, 39 inside thereof. A slit 41 is formed in the support piece 33, and a guide rod 43 passes through the support pieces 33 and 35. The guide rod 43 has its upper end abutted against the support piece 37, and the enlarged diameter portion 45 formed on the guide rod 43 is engaged with the support piece 35.

  The swing arm 11 is connected to the support piece 39 via a first pin 49 inserted through a shaft hole 47 formed at the rear end thereof, and is directed in the direction indicated by the arrows R and F with the first pin 49 as a fulcrum. You can turn. The direction pointed by the arrow F is referred to as “motion direction” below. The tip 51 of the swing arm 11 is formed flat. A shaft hole 53 is formed in the longitudinal direction of the swing arm 11. The trigger 15 is a lever in which a claw portion 57 is provided on a rectangular piece in which a long hole 55 is formed. The first pin 49 is inserted into the elongated hole 55 of the trigger 15 together with the shaft hole 47 of the swing arm 11, and the trigger 15 can turn in the same direction as the swing arm 11 with the first pin 49 as a fulcrum.

  The slider 7 is a gate-shaped metal fitting having one side piece 59 and another side piece 61, and is guided by the guide rod 43 so as to be raised and lowered at a position higher than the first pin 49. The other side piece 61 is inserted into the slit 41 of the support piece 33, and a plurality of check claws 65 are formed in a sawtooth shape. The spring 9 is a compression coil spring that is disposed around the guide rod 43 between the slider 7 and the support piece 35 and generates a force that pushes the slider 7 downward.

  The connecting rod 13 is formed with shaft holes 67 and 69 at its lower end and upper end, respectively. The swing arm 11 and the connecting rod 13 are rotatably connected to each other via a second pin 71 that penetrates the shaft holes 53 and 67. The upper end of the connecting rod 13 is connected to one side piece 59 of the slider 7 via a third pin 73 inserted through the shaft hole 69. The force of the spring 9 is transmitted to the swing arm 11 via the connecting rod 13.

  Rivets or the like may be applied as the first to third pins 49, 71, 73. The elements described so far constitute the operation part 3, and an assembly drawing thereof is shown in FIG. Reference numeral 75 denotes a reflector in which a light bulb or the like is installed.

  The procedure for constructing the implantable attachment device 1 will be described below. First, the opening 19 is formed in the ceiling plate 17. Alternatively, a ceiling board having a pre-made opening 19 is prepared. The diameter of the opening 19 may be larger than the disk 27 of the support 5 and smaller than the edge member 21.

  As shown in FIG. 4, the second pin 71 is positioned at a dead point with respect to the connecting rod 13 when the swing arm 11 takes the standing posture. Here, the dead point is not limited to the fact that the first and second pins 49 and 71 form a line strictly in the longitudinal direction of the connecting rod 13, and the first pin 49 has an arrow R rather than the above dead point. It is also possible to turn in the direction, in other words, to move back to a position where the operation direction is slightly reversed. In this case, the connecting rod 13 is provided with a stopper 77 that defines a limit at which the swing arm 11 can reverse the operation direction.

  Subsequently, the operator makes the trigger 15 in a horizontal posture and extends outward from the support 5, and engages the claw portion 57 of the trigger 15 with the swing arm 11. The operator holds the implantable attachment device 1 and raises the implantable attachment device 1 from directly below the opening 19 of the ceiling plate 17, thereby inserting the support 5 into the opening 19. In this process, as shown in FIG. 5, the peripheral edge of the opening 19 of the ceiling plate 17 contacts the trigger 15, and the trigger 15 receives an external force from the ceiling plate 17 and turns in the operation direction. At the same time, the swing arm 11 turns in the operation direction according to the trigger 15, and when the second pin 71 deviates from the dead point, the swing arm 11 receives the force of the spring 9 and rapidly turns in the operation direction. Thereby, as shown in FIG. 6, the tip 51 of the swing arm 11 is close to the ceiling plate 17, and the ceiling plate 17 can be sandwiched between the tip 51 of the swing arm 11 and the edge member 21.

  Since the construction is completed by the above procedure, according to the implantable attachment device 1, it is not necessary to particularly perform the work of fixing the support 5 to the ceiling plate 17, and the lighting fixture 31 can be quickly placed in the opening 19 of the ceiling plate 17. And can be installed easily. Moreover, the embedded mounting device 1 does not require metal fittings for positioning the support 5 on the ceiling plate 17 and has an advantage that it is not necessary to tighten bolts or the like.

  Further, as described above, the swing arm 11 swings in the operation direction as the slider 7 descends. In this process, the check pawl 65 of the other side piece 61 is in sliding contact with the mouth edge of the slit 41, but when an upward external force is applied to the slider 7 shown in FIG. Engage with. As a result, the slider 7 is prevented from rising, so that the swing arm 11 having the tip 51 close to the ceiling plate 17 does not inadvertently return in the direction of the arrow R. This effect can be achieved even when any one of the plurality of check claws 65 is engaged with the lip of the slit 41 and the embedded mounting device 1 is attached to a ceiling plate having a thickness different from that of the ceiling plate 17. The

  When removing the mounting device 1 from the ceiling plate 17, the operator presses the other side piece 61 with his / her finger in the direction in which the check claw 65 separates from the lip of the slit 41 and swings against the force of the spring 9. The arm 11 is turned in the arrow R direction. As a result, the swing arm 11 is in a standing posture, and when the second pin 71 reaches the dead point, the implantable attachment device 1 returns to the state shown in FIG. Thereafter, the implantable attachment device 1 can be immediately removed from the ceiling board 17 simply by lowering the implantable attachment device 1 by an operator.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the slider 7, the spring 9, and the connecting rod 13 shown in FIGS. 2 and 3 constitute a biasing means 79 that generates a force for turning the swing arm 11 in the operation direction. You may do it. Further, the connecting rod 13 and the first and second pins 49 and 71 constitute a holding means 81 for restricting the swing of the swing arm 11 taking an upright posture. The arrangement of the pins 49, 71, 73 can be changed as appropriate. The edge member 21 is not necessarily ring-shaped. The implantable attachment device 1 preferably includes two or more operation units 3.
