A pair of energizing male fittings 26 are housed together with a protector 37 and a spring 38 while being pressed by a holding plate 39. The spring 38 has an axis directed in the radial direction of the main body 27A, and a bottom of the recessed hole 27F so that the energizing male fitting 26 and the protector 37 are both pushed out in the horizontal direction toward the center of the through hole 25. It is interposed between the base of the protector 37. The holding plate 39 is fixed to the main body 27A with screws 27G. The protector 37 is provided side by side on the hooking pawl 28 side of the energizing male metal fitting 26, and prevents a hand from inadvertently touching the energizing male metal fitting 26 when operating the operating nail 36. Have. Specifically, as shown in FIG. 9, the base portion of the current-carrying male fitting 26 is fitted to the base portion of the protector 37 in a state that the base portion of the protector 37 is projected to be slightly shorter than the tip protruding position of the protector 37. The spring 38 is interposed between the base of the protector 37 and the bottom of the recessed hole 27F. Further, a current-carrying metal fitting 40, which allows the current-carrying male metal fitting 26 to slide and is electrically connected, is fitted into the recessed hole 27F, and is further electrically connected to the current-carrying metal fitting 40.

A cam guide 24N for smoothly introducing or withdrawing the tip cam surface 37A into or from the slit 24M is formed, and the tip cam surface 37A is guided by the cam guide 24N so that the pressing force of the spring 38 is exerted. Against this, the energizing male fittings 26 are once pushed into the recessed holes 27F, and after passing through the cam guide 24N, they are again projected by the pressing force of the spring 38, and then into the slits 24M of the hooking ceiling 24, and again. The energizing male fittings 26 are fitted into the hooking slits 24I, respectively. Although not shown, a cam guide similar to the cam guide 24N is provided at the opening end of the slit 24I formed facing the current-carrying female metal fitting 22, that is, the end of the slit 24I on the lid 24D side. Can be adopted.

Reference numeral 42 in the drawing denotes an arc-shaped elongated hole formed in a symmetrical position of the main body 27A of the ceiling receiving member 27. The ceiling receiving member 27 is attached to the chassis 21A of the lighting fixture 21. A screw 21C (see FIG. 6) for mounting is inserted, and the mounting angle of the sealing receiving member 27 with respect to the chassis 21A is freely changed within the range of the long hole 42.

As shown in FIG. 6, there are a reflector 21D, a lamp holder 21E also serving as a lamp socket, a lamp support spring 21F, a fluorescent lamp 43, and a globe on the lower surface of the chassis 21A of the luminaire 21. A cover can be detachably attached to the central lower surface opening of the chassis 21A communicated with the through hole 25, if necessary.

In the above-described embodiment, as shown in FIGS. 12 and 13, the hooking ceiling rosette C (in FIG. 12, when the embedded hooking ceiling rosette is used, and in FIG. 13 the hooking ceiling rosette is used). (The operation state when a rosette is used is shown.) After the hook ceiling 24 is attached, the lighting fixture 21 (not shown) is pushed up and the ceiling receiving member 27 opened on the upper surface of the lighting fixture 21. Simply by inserting the hooking ceiling 24 into the through hole 25, the current-carrying female metal fitting 22 provided on the side surface of the hooking ceiling 24 is electrically connected to the current-carrying male metal fitting 26 on the lighting fixture 21 side. The hooking claw 28 provided on the sealing receiving member 27 is locked to the locking portion 29 provided on the side surface of the hooking ceiling 24, whereby the ceiling receiving hook 24 receives the sealing hook. The retaining member 27 is attached. As described above, the lighting fixture 21 can be easily attached as if it were directly attached to the ceiling A. Further, even when the lighting fixture 21 is removed, the operating claws 36 are slid horizontally with respect to each other and away from the center of the lighting fixture 21 against the pressing force of the spring 34. The illuminator 21 can be easily removed because the illuminator 21 is retracted and disengaged from the locking portion 29, and the illuminator 21 can be simply pulled down.

By the way, in the lighting fixture used in this embodiment, since the hook ceiling 24 is configured to include the metal fixture fixing bracket 33, it is formed on the left and right hanging pieces 32 of the fixture fixing bracket 33. The weight of the lighting fixture 21 loaded on the locked portion 29 is dispersed from the hanging piece 32 of the fixing fixture 33 to the upper plate 31, and the weight after the dispersion is hooked to the ceiling of the ceiling 24. Since the load is applied to the plate 24A, the weight of the luminaire 21 is dispersed and applied to the entire ceiling plate 24A of the hook ceiling 24. Therefore, it is not necessary to consider the increase in the strength of the hook ceiling 24 itself, and the hook ceiling 24 can be designed compact in all aspects such as bulk and wall thickness, and the overall lighting fixture can be made thinner.

The energizing male fitting 26 and the hook 28 are configured to slide horizontally together, and in addition, the operating hook 36 integrally provided on the lower surface of the hook 28 has an operating hook 36. Since the hooking pawl 28 is operated by sliding operation in the horizontal direction, the bulk of the sealing receiving member 27 is formed to be remarkably compact, and further thinning can be achieved.

(Example 2) In Example 1, the lower surface of the hooking ceiling 24 is formed into a flat surface, but as shown in FIGS. 3 to 4, 6 to 7 and FIG. On the lower surface of the hooking ceiling 24, a structure is adopted in which a semi-arcuate recessed groove 45 whose center is convex upward is formed by aligning the center with a substantially central position between the left and right straight side walls 24L. You can In the hooking ceiling 24, the current-carrying female metal fitting 22 and the lock pin 24J are arranged at the corner portion of the body 24C, so by making good use of the structural characteristics that other parts do not exist in the central portion, This recessed groove 45 is successfully formed. This recessed groove 45 is fully utilized when it is used in a lighting fixture equipped with a straight tube fluorescent lamp, and the recessed groove 45 is used in the upper half of the straight tube fluorescent lamp 43. As compared with the case of the first embodiment, the vertical height of the mounting device is reduced by at least half of the vertical dimension of the fluorescent lamp 43 of the straight tube. Can be realized.

(Third Embodiment) In the first embodiment, the current-carrying male fitting 26 is formed by the spring 38 in the through hole 25 of the sealing receiving member 27 so as to project freely. As shown, there is provided a click mechanism 46 in which the current-carrying male fitting 26 is held in two predetermined positions, that is, the posture in which it projects into the through hole 25 and the posture in which it retracts into the recessed hole 27F. It moves in and out by manual operation without using a spring. Specifically, on the side wall of the recessed hole 27F, there are two positions, that is, a position where the energizing male metal fitting 26 is projected into the through hole 25 and a position where the tip is retracted from the through hole 25 into the recessed hole 27F. A recessed hole 46A is formed at a position corresponding to, and a protrusion 46B is formed on the base of the protector 37, and the current-carrying male fitting 26 is retracted into the recessed hole 27F and the posture in which it is projected into the through hole 25. The projections 46B are fitted into the recessed holes 46A at two predetermined positions, that is, the two positions of the conducting male fitting 26 are fixedly held.

Further, in the case of the present example, the operation claw 47 is integrally formed on the lower surface of the base portion of the protector 37 in the same manner as the hook claw 28, and the sealing receiving member is formed. The operation claw 47 is fitted on the lower surface of the main body 27A of 27, and an operation hole (not shown) penetrating from the concave hole 27F to the lower surface of the main body 27A is formed so that the operation claw 47 can slide from the lower surface of the main body 27A. Has been drilled.

(Fourth Embodiment) In the first embodiment, the hooking claws 28 are formed in the through holes 25 of the sealing receiving member 27 by the springs 34, respectively. As shown in FIG. 5, there is provided a click mechanism 48 in which the hooking claw 28 is held in two predetermined positions, that is, the posture in which it is projected into the through hole 25 and the posture in which it is retracted into the recessed hole 27C. The hook claw 28 is moved in and out by manual operation without using a pulling. Specifically, there are two positions on the side wall of the recessed hole 27C: the position where the hook 28 is projected into the through hole 25 and the position where the tip is retracted from the through hole 25 into the recessed hole 27C. A recessed hole 48A is formed at a position corresponding to the position, and a projection 48B which can be fitted into the recessed hole 48A is integrally formed on the side surface of the base of the hooking claw 28 so as to project integrally. The protrusions 48B are fitted into the recessed holes 48A at two predetermined positions, that is, a position in which they are projected into the through holes 25 and a position in which they are retracted into the recessed holes 27C, and the hooking pawls 28 are 2 postures are fixedly held. In this case, it is needless to say that the operation of the hook 28 is carried out by the operation claw 36.

Fifth Embodiment In the third embodiment, the click mechanism 46 employs a configuration in which the energizing male metal fitting 26 is held in the two retracted positions. Since the plug male blade 22A elastically clamps the energizing male metal fitting 26 (see FIG. 9), by utilizing the function of the female electromechanical metal fitting 22, the click mechanism 46 is not used. Can also be adopted. That is, the left and right holding parts 40A (see FIG. 9) at the tip of the current-carrying metal fitting 40, which are electrically connected to the current-carrying male metal fitting 26 from both the left and right sides thereof, are provided with elastic spring forces in directions toward each other. Then, the energizing male metal fitting 26 is elastically held from both sides by the both holding portions 40A. As a result, the energizing male metal fitting 26 elastically moves between the receiving blade 22A of the energizing female metal fitting 22 and the left and right holding parts 40A of the tip of the energizing metal fitting 40 in an operating state in which it is electrically connected to the energizing female metal fitting 22. When it is held, its working posture is well maintained, and when it is in the non-working posture in which it is retracted from the through hole 25, its retreat working posture is well held by both the holding portions 40A.

(Embodiment 6) Further, although the current-carrying male fitting 26 is configured to be capable of retracting and retracting, without adopting such a configuration, although not shown, the projecting male member 26 is always kept in a protruding posture as necessary. It is also possible to adopt a configuration in which the sealing receiving member 27 is fixedly attached. Further, the protector 37 can also be constructed by removing it if necessary. However, in the case where the energizing male metal fitting 26 is retracted, it goes without saying that the part 37F for holding the electrically conductive male metal fitting 26 at a portion corresponding to the base portion of the protector 37 is necessary.

It should be noted that the above-mentioned respective embodiments, particularly the mutual combination of the automatic male and female operations and the automatic operation and manual operation relating to the withdrawal and retraction of the hook 28 can be freely combined as necessary, and are not necessarily as illustrated. It is not limited to only the combination of operating means.

The luminaire 1 in the present invention corresponds to the luminaire 21 in this embodiment, the hook plug blade 3 corresponds to the hook plug blade 23, the hook ceiling 4 corresponds to the hook ceiling 24, and electricity is supplied. The male fitting 5 corresponds to the energizing male fitting 26, the through hole 6 corresponds to the through hole 25, the sealing receiving member 7 corresponds to the sealing receiving member 27, and the locked portion 8 corresponds to the hooking pawl 28. The locking portion 9 corresponds to the locking portion 29, the operating portion 10 corresponds to the operating claw 36, the upper plate 11 corresponds to the upper plate 31, the hanging piece 12 corresponds to the hanging piece 32, and the device fixing bracket 13 Corresponds to the fixture fixing bracket 33, and the hook sealing main body 14 corresponds to the main body 27A.

Is superposed on the upper surface and the left and right side surfaces of the plastic hook ceiling main body 14 respectively, and the left and right hanging pieces 12 of the device fixing bracket 13 are formed into a ladder shape with a plurality of upper and lower stages. The locking portion 9 is integrally formed, faces the inside 15 of the window formed in the lower surface of the sealing receiving member 7, and extends outward from the center of the sealing receiving member 7. An operation portion 10 that is horizontally pressed from the lower surface of 7 is integrally formed on the lower surface of the locked portion 8, and the load of the lighting fixture side is passed through the locking portion 9 to the upper plate of the fixture fixing bracket 13. 11 also bears, and the upper surface of the ceiling body 14 is also hooked Also, unlike the conventional way of intensively loading on the plastic locking part, the load is shared by the two members, the fixture fixing bracket 13 and the hook ceiling body 14. Since it is supported, the strength of the hook ceiling body 14 can be significantly improved as compared with the hook ceiling made of conventional resin alone, and as a result, the resin meat forming the body of the hook ceiling can be improved. In addition to being able to make the thickness remarkably thin, the bulk can also be constructed to a tremendous thinness, which is one-third of that of the conventional one, and it has been made extremely compact. At the same time, the sealing receiving member 7 and the operating portion 10 integrally formed with the sealing receiving member 7 for operating the sealing receiving member 7 are configured to be operated and slid only in the horizontal direction. As compared with the means in which the operating portion is vertically operated with respect to the member, the mounting device has been made thinner.

According to a second aspect of the present invention, a through groove 45 having a convex center is formed on the lower surface of the hook ceiling body 14, and a straight fluorescent tube is provided with an upper half portion thereof. Since it can be installed in the penetrating groove 45, the vertical height of the mounting device can be reduced by at least half of the vertical dimension of the fluorescent lamp of the straight tube. Thinning has been achieved.

According to the third aspect of the invention, when the ceiling receiving member 7 is hooked and detached from the ceiling 4, the operator's finger operating the locked portion 8 reaches the energizing male metal fitting 5 and is not prepared. Since it protects against contact with, it contributes to further improvement of safety.

The invention according to claim 4 contributes to attaching / detaching the sealing receiving member 7 to / from the sealing 4 with one touch.

Since the inventions according to claims 5 and 7 enable the energizing male fitting 5 to enter and leave the guide groove without the entrance and exit, for example, as shown in FIG. The lower part of the plug can be completely closed, and not to mention the smart appearance, the current-carrying male fitting 5 is completely hooked inside the ceiling 4 at the time when the current-carrying male fitting 5 electrically contacts the current-carrying female fitting 2. However, unlike the conventional structure, the vertical length of the guide groove portion between the current-carrying male fitting 5 and the current-carrying female fitting 2 is remarkably short because there is no part exposed to the outside of the device. The hook ceiling 4 can be made even thinner.
