Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a lighting fixture mounting device which can be combined with both a thick hook ceiling outlet and a thin hook ceiling outlet provided on a ceiling surface or the like and has durability of its own weight strength. .

[0002]

[Prior art]

 The fixed side fixture of the conventional lighting fixture mounting device has a plug part with a hook ceiling plug that engages with a hook ceiling outlet on the upper surface, and a round brim-shaped lower stage support part that projects outward on the lower surface of the round tubular part. It is equipped with a pair of claws that open and close inside the tubular part of the detachable device that is integrated with the lighting fixture. At this time, it is desirable to be able to combine a thick hook ceiling outlet provided on the ceiling surface and a thin hook ceiling outlet type with a small gap on the ceiling surface. However, using two steps for opening and closing movements has drawbacks such as complicated structure and increased cost.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to remedy the above-mentioned drawbacks by providing a circular lower surface metal fitting that engages with the lower surface of the round brim-shaped lower stage supporting portion projecting outward on the lower surface of the circular cylindrical portion, and facing the same. A circular top fitting is provided on the top of the round tube, and a pair of claws that opens and closes inside the tube on the side of the lighting fixture is used to attach or detach either the outer circumference of the round top fitting or the outer circumference of the round brim-shaped lower support. Make the structure As a result, it rotates in a pair of claws that open and close inside the tubular part of the detachable device that is integrated with the luminaire as before, so it has the advantage that the orientation of the luminaire can be freely selected. Both the thick hook ceiling outlet and the thin hook ceiling outlet can be combined with a small gap on the ceiling surface, and the pair of claws should be in one step and the opening and closing part should be in two steps. The present invention intends to provide a structure of a lighting fixture mounting device which can cope with the above-mentioned problems, has durability of the weight of the lighting fixture itself, has a one-way assembling property, and can be manufactured at low cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a lighting fixture mounting device of the present invention comprises a circular lower surface metal fitting that engages with the lower surface of a round brim-shaped lower stage support portion protruding outward from the lower surface of the round tubular portion, and a circular lower surface metal fitting facing the lower surface metal fitting. The upper surface of the round tubular part is equipped with a circular top fitting, and a pair of one-step claws that open and close to the inside of the tubular part on the side of the luminaire are provided on the outer circumference of the circular upper fitting or the outer circumference of the round brim-shaped lower support part. Either of these is attached or detached.

[0005]

[Action]

 The fixed-side device has a plug part with a pair of hook sealing plugs that engage with the hook ceiling outlet on the upper surface, and a round brim-shaped lower stage support part that projects outward on the lower surface of the round tubular part. A circular lower surface metal fitting that engages with the lower surface of the collar-shaped lower support, and a circular upper surface metal fitting is provided on the upper surface of the round tubular part facing this, and tighten the circular upper metal fitting from the circular lower metal surface side with a fixing means such as a screw. As for the detachable side device, the detachable side device holds a pair of claws that open and close inside the cylindrical part of the detachable side device, and the outer periphery of the circular upper surface metal fitting or the outer periphery of the round brim-shaped lower stage support part is held by the one-step claw portion.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the lighting fixture mounting device includes a fixed-side fixture 1 and a removable-side fixture 2. The attachment / detachment is structured such that the attachment / detachment side device 2 is attached / detached by a pair of claw portions that open / close move inside the tubular portion. At this time, it is desirable that both the thick hook ceiling outlet and the thin hook ceiling outlet provided on the ceiling surface can be combined with a small gap on the ceiling surface. FIG. 2 is an explanatory view showing the former, and FIG. 3 is an illustration showing that the latter can be engaged in combination corresponding to the latter. Details of the fixed-side instrument 1 will be described with reference to FIGS. The fixed-side instrument 1 has a plug portion 4 provided with a pair of hook sealing plugs for engaging with hook ceiling outlets on an upper surface 3, and a round brim-shaped lower stage support portion 6 protruding outward on a lower surface of a round tubular portion 5. A circular lower surface metal fitting 7 that engages with the lower surface of the round brim-shaped lower stage support portion 6 is provided, and a circular upper surface metal fitting 8 is provided on the upper surface 3 of the circular cylindrical portion facing the circular lower surface metal fitting 7. 9 is a fixing means such as a screw for tightening the circular upper surface metal fitting 8 from the circular lower surface metal fitting 7 side. The screw engaging portion of the circular upper surface metal fitting 8 is a recess 10 so that the tip of the screw is deeper than the upper surface 3. Reference numeral 11 represents a cord set, and 12 is an insulating frame that insulates the inner surface of the plug portion 4 and forms the lead-out portion of the cord set 11. In FIG. 1, reference numeral 13 denotes a pair of one-step claw portions that open and close inside the tubular portion of the attachment / detachment side device 2. In FIG. 2, the outer periphery of the circular upper surface metal fitting 8 is semi-fixed by pressing the outer periphery of the round brim-shaped lower stage support portion in FIG. Since the lighting device is integrated with the detachable side device 2 by a procedure such as using the outer peripheral hole 14, the detachable side device 2 can be easily detached from the fixed side device 1.

[0007]

[Effect of device]

 Since the present invention is laterally formed as described above, it has the following effects. As described above, the fact that the attaching / detaching side device 2 can be easily attached / detached from / to the fixed side device 1 makes it possible to easily attach / detach the lighting device. It has the advantage that the direction of the lighting fixture can be freely selected because it rotates within a pair of claws that open and close inside the tubular part of the detachable fixture that is integrated with the lighting fixture as before. Both the ceiling hook ceiling plug socket and the thin hook ceiling plug socket type can be combined with a small gap on the ceiling surface, and the pair of claws 13 can be set in one step without opening and closing the moving parts in two steps. Therefore, the structure is simplified, the operation is ensured, and the manufacturing cost is reduced. The weight of the lighting fixture is semi-fixed by pressing the outer periphery of the circular upper surface metal fitting 8 in FIG. 2 and the round brim-shaped lower stage support in FIG. Even when the number of fixing screws of the circular upper surface metal fitting 8 is two as in the embodiment, the moment acts on the force for bending the outer circumference of the metal fitting downward, and this point has a strong strength that acts on the compression resistance of the round tubular member 5. It has strength and durability without being damaged even if it is loaded for a long period of time. The circular lower surface metal fitting 7 that engages with the lower surface of the collar-shaped lower stage support portion 6 is reinforced, and the circular cylindrical portion 5 is sandwiched between the circular upper surface metal fittings 8 so as to be stronger. It has a reliable structure. The circular top metal fitting 8 is used as the bottom surface so that it can be assembled in one direction and can be manufactured at low cost.
