DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture mounting apparatus for mounting a lighting fixture to a hook-type ceiling wiring device such as a hanging ceiling provided on a ceiling or a hooking embedded rosette.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing a conventional lighting fixture mounting structure generally used. In the figure, in order to attach the lighting fixture main body 103 to the hanging ceiling wiring fixture 101 provided on the ceiling, first, a disk-shaped lighting fixture mounting device 102 is attached to the hanging ceiling wiring fixture 101. Next, the fitting tube portion 104 of the lighting fixture main body 103 is externally inserted into the lighting fixture mounting device 102. A pair of claws 1 urged inward by a spring (not shown) inside the fitting tube portion 104.
The claw 105 is engaged with the lighting fixture mounting device 102 to hold the lighting fixture main body 103. The claw 105 is tapered at its distal end so that the lighting fixture body 103 can be smoothly inserted into the lighting fixture mounting device 102. Further, when the lighting fixture main body 103 is detached from the lighting fixture mounting device 102, the claw 105 can be forcibly opened by the operation lever 106.

FIG. 13 is a perspective view of the lighting fixture mounting device 102 as viewed obliquely from below. Lighting fixture mounting device 102
Is provided with a pair of blades 107 for hooking connection with the hook-type ceiling wiring device 101 (FIG. 12). A groove 102a is formed in the circumferential direction of the side surface, and a substantially C-shaped (see FIG. 14) ring 108 is mounted therein. The ring 108 is detachable, and is attached and detached according to the type of the hook-type ceiling wiring device 101. For example, when the hook-type ceiling wiring device 101 is a hook-type ceiling (completely exposed type) as shown in FIG. 12, the lighting device main body 103 is attached with the ring 108 attached. In this case, the pawl 105 climbs over the outer peripheral surface of the ring 108 to reach the upper surface of the lighting fixture mounting device 102 and engages there. Thereby, the lighting fixture main body 103 is held. On the other hand, if the hook-type ceiling wiring device 101 is a hook-embedded rosette (semi-embedded type) whose protruding length from the ceiling is shorter than the hook ceiling, the ring 108 is removed and the groove 102 is removed.
a is not blocked. In this case, when the fitting tubular portion 104 is externally inserted into the lighting fixture mounting device 102, the claw 105
02a. Therefore, the lighting fixture body 103 can be stably held at that position.

In this manner, the mounting position of the lighting fixture body 103 in the height direction can be adjusted by attaching and detaching the ring 108. As a result, the distance between the ceiling of the lighting fixture body 103 and the ceiling can be kept substantially constant regardless of the type of the hook-type ceiling wiring fixture 101. A spacer (also used as an insect repellent) for suppressing rattling of the lighting fixture body 103 is attached between the upper portion of the lighting fixture body 103 and the ceiling.

[0005]

However, in the conventional lighting fixture mounting apparatus 102 as described above, the mounting operator sometimes mistakenly attaches or detaches the ring 108. For example, if the installation worker accidentally removes the ring 108 even though the hook-type ceiling wiring device 101 is a hanging ceiling, the lighting device body 103 can be mounted, but the upper surface and the ceiling can be mounted. Becomes larger than the appropriate value. As a result, particularly in the case of a lighting apparatus provided with a horizontal pulling switch (a switch string is suspended horizontally after being stretched horizontally), the lighting apparatus main body 10 is operated by the switch operation.
3 swings and becomes unstable. Conversely, if the ring 108 is not removed even though the hook-type ceiling wiring device 101 is a hook-mounted embedded rosette, the lighting fixture body 10
3 cannot be attached. As described above, there is a problem that if the installation operator makes a mistake in attaching and detaching the ring 108, the lighting fixture cannot be properly attached.

[0006] In view of the above-mentioned conventional problems, the present invention provides a lighting fixture mounting apparatus capable of always and properly mounting a lighting fixture main body without depending on the attention of a mounting operator. The purpose is to:

[0007]

SUMMARY OF THE INVENTION A lighting fixture mounting apparatus according to the present invention is a lighting fixture mounting apparatus connected to at least two types of hook-type ceiling wiring devices having different protruding lengths from a ceiling. A first end having a plug blade hooked and connected to the wiring fixture on an end face, and having a first support portion that selectively engages with an engaging portion on the side of the lighting fixture main body to support the lighting fixture main body; The mounting member engages with the first mounting member and is movable with respect to the first mounting member within a predetermined range in a direction orthogonal to the ceiling surface, and interferes with one hook-type ceiling wiring device. A second mounting member having a projection that interferes with another hook-type ceiling wiring device and a second support portion that selectively engages with the engagement portion and supports the lighting device body. In a free state, the protrusion should be maintained in a state protruding from the end face. An elastic body for urging the second mounting member relatively to the first mounting member, wherein the first support portion is provided when the blade is hooked and connected to the one hook-type ceiling wiring device. When the lighting device main body is supported by the above and the plug blade is hooked and connected to the other hook-type ceiling wiring device, the protrusion of the second mounting member is brought into contact with the hook-type ceiling wiring device. By pushing the first attachment member against the elastic body, the second attachment member is relatively moved with respect to the first attachment member, and based on this movement, the difference in the protruding length is canceled. The lighting device main body is supported by the second support portion moved in the direction in which the lighting device is moved (claim 1).

In the lighting fixture mounting apparatus thus configured, when the plug blade is hooked and connected to the hook type ceiling wiring device, the first support portion supports the lighting fixture main body. On the other hand, when the plug blade is hook-connected to the other hook-type ceiling wiring device, the first mounting member is opposed to the elastic body from a state in which the protrusion of the second mounting member is in contact with the hook-type ceiling wiring device. By pressing, the second mounting member is relatively moved with respect to the first mounting member, and based on this movement, the second support portion, which has moved in a direction to offset the difference in the protruding length, has a lighting device body. Support the part. Therefore, the difference in the projection length from the ceiling surface due to the type of the hook-type ceiling wiring device can be compensated for by changing the support portion, and the distance between the lighting fixture body and the ceiling surface can be kept substantially constant.

In the above-mentioned lighting fixture mounting apparatus, the second mounting member is substantially below the first mounting member in a state of being hooked and connected to the hook type ceiling wiring device, and the first mounting member has a first side mounted on a side surface thereof. A notch for exposing a part of the mounting member downward may be provided (claim 2). In this case, it is possible to perform an operation of attaching the lighting fixture attachment device while passing the finger through the notch and pushing up the first attachment member with the fingertip.

In the lighting fixture mounting device (claim 2), a pressing plate for holding a spring as the elastic body is disposed below the second mounting member, and the pressing plate is also provided with the first mounting member. A notch for exposing a part downward may be provided (claim 3). In this case, it is possible to perform an operation of turning the lighting fixture attaching device while putting the finger on the notch and pushing up the first attaching member with the fingertip.

[0011] In the lighting fixture mounting device (claim 1), when the lighting fixture main body is supported by the second support, the difference in height between the first support and the second support is different. Preferably, the difference between the protrusion lengths is substantially equal to the difference between the protrusion lengths. In this case, the difference in the protruding length depending on the type of the hook-type ceiling wiring device is surely offset by the difference in the height position of the support portion. Therefore, the distance between the lighting fixture body and the ceiling surface can be kept constant.

A pair of blades 11 hooked and connected to the hook-type ceiling wiring device is provided to protrude upward from the upper surface 1a. Escape holes 1d are provided at four locations on the same circumference as the periphery of the upper surface portion 1a so as to fit a projection 2d of the second mounting member 2 described later. Further, a pair of holes 1e of the upper surface portion 1a is provided to allow the screw 7 (FIG. 1) to pass therethrough. On the other hand, as shown in FIG. 2C, a pair of lead wire terminals 12 respectively connected to the blade 11 is provided on the back side of the upper surface portion 1a (however, illustration of the lead wire is omitted). .).

The side surface portion 1b of the first mounting member 1 is cut out at two opposing predetermined ranges on the outer periphery to form a cutout portion 1f. A protrusion 1g is provided at a circumferential edge of the side surface 1b along the notch 1f. The flange-shaped portion 1c is provided at a lower end of the outer periphery of the side surface portion 1b except for the pair of cutouts 1f, and has a function as a “first support portion” that supports the lighting fixture body (details will be described later). I do.)

Next, FIG. 3 is a view showing the second mounting member 2, wherein (a) is a plan view, (b) is a side view, and (c) is a bottom view. 1 and 3, the second mounting member 2
Is made of resin, and its basic shape is an upper surface portion 2a shaped as a part of a circle and a partially cylindrical side surface portion 2b
And a flange 2c formed at the lower end of the outer periphery of the side surface 2b. The four protruding portions 2d are provided to protrude upward from the outer peripheral end of the upper surface portion, and are arranged on the same circumference so as to be inserted into the escape holes 1d of the first mounting member 1 described above. The spring holding portion 2e is formed by press-forming the center of the upper surface portion 2a, and is a convex portion in FIGS.
(C) is a concave portion. The pair of square holes 2 f formed with the spring holding portion 2 e interposed therebetween serve as escape holes for the lead terminal 12. Further, a pair of round holes 2g is formed with the spring holding portion 2e interposed therebetween so as to insert the guide member 4. FIG. 1 shows a pair of bosses 2h projecting behind the upper surface 2a.
A female screw for screwing the screw 8 is formed.

The side surface 2b and the upper surface 2 of the second mounting member 2
In a, two opposite predetermined ranges on the outer circumference are cut away to form notches 2i. The flange portion 2c is provided at the lower end of the outer periphery of the side surface portion 1b except for the pair of cutout portions 2i, and has a function as a “second support portion” that supports the lighting fixture body (details will be described later). I do.) Flange 2c
Is tapered so that its outer diameter decreases toward the bottom.

As shown in FIG. 1, a lighting fixture mounting device 10 is provided.
The first mounting member 1 and the second mounting member 2 configured as described above are further provided with a spring 3, a resin guide member 4, a metal holding plate 5, a metal cover 6, a screw 7, and a screw. 8 is assembled. Here, the spring 3 is a compression spring. The guide member 4 has a stud-like external shape, and has a through hole 4a through which the screw 7 is inserted.
Further, the cylindrical portion (the portion excluding the tack head) 4b of the guide member 4
Is smaller than the inner diameter of the round hole 2g of the second mounting member 2 described above. A press-formed spring holding portion 5a is formed as a recess at the center of the holding plate 5, and female screw portions 5b are formed on both sides of the spring holding portion 5a. The holding plate 5 has an escape hole 5 for the boss 2h of the second mounting member 2.
c is provided, and a notch 5d cut from the outer periphery of another circular portion is provided. The cover 6 is provided with a pair of holes 6a through which the screws 8 are inserted, and an arc-shaped notch 6b at an opposite position on the outer periphery.

Here, assuming that the vertical direction of the drawing, that is, the direction perpendicular to the ceiling surface on which the lighting fixture mounting device 10 is mounted is the “axial direction” of the device, the notch 5 d of the pressing plate 5 in a plane perpendicular to the axial direction. The cutout area by the second
The notch 2i of the mounting member 2 is arranged so as to overlap with a notch area on the same plane. That is, when the device is viewed in a plan view, at least a part of a region depressed from the outer periphery of the entire device due to the presence of the notches 5d and 2i is common. Similarly, the cutout area formed by the cutout portion 6b of the cover 6 in a plane orthogonal to the axial direction is also arranged so as to overlap the cutout area of the cutout portion 2i of the second mounting member 2 in the same plane. Therefore, the cutout areas on the plane orthogonal to the axial direction by the cutout portion 6b of the cover 6, the cutout portion 5d of the holding plate 5, and the cutout portion 2i of the second mounting member 2 coincide with each other within a predetermined range. The position on the circumference of the notch 2i of the second mounting member 2 substantially coincides with the position on the circumference of the notch 1f of the first mounting member 1.

To assemble the lighting fixture mounting apparatus 10,
First, the first mounting member 1 and the second mounting member 1 are inserted such that the protrusion 2d of the second mounting member 2 is inserted into the escape hole 1d of the first mounting member 1.
The mounting members are engaged with each other. Next, the spring 3 is connected to the spring holding portion 2 e of the second mounting member 2 and the spring holding portion 5 of the holding plate 5.
a and the cylindrical portion 4b of the guide member 4 is
The holding plate 5 is inserted into the round hole 2 g of the mounting member 2.
And the second mounting member 2 are pressed against each other. In this state, the screw 7 is passed and screwed into the female screw portion 5 b of the holding plate 5.
Finally, the cover 6 is fixed to the second mounting member 2 with the screws 8.

In the lighting fixture mounting apparatus 10 assembled and completed as described above, the second mounting member 2 is the first mounting member 1.
And the guide by the guide member 4 regulates rotation in a plane perpendicular to the axial direction, and in the axial direction, the rotation of the spring 3 against the first mounting member is prevented. In a predetermined range. Further, as described above, the notch 6b of the cover 6, the notch 5d of the holding plate 5, and the second
The notch 2i of the mounting member 2 has a common notch area on a plane orthogonal to the axial direction, and the notch 2 of the second mounting member 2
The position on the circumference of i is the notch 1f of the first mounting member 1.
, A predetermined concave space continuous in the axial direction is formed.

FIG. 4 is a side view of the lighting fixture mounting apparatus 10 assembled as described above. As shown in the figure, a concave portion V is formed so as to penetrate inward from the side surface and the side surface. The concave portion V is a concave portion that can be touched by a human finger when the lighting fixture mounting device 10 is mounted. In addition, since the notch is not provided in the upper surface 1a of the first mounting member 1, a part of the back surface of the upper surface 1a is exposed downward (a state that can be seen from below), and the tip of the finger is there. The pressing force is applied. In other words, the thumb and forefinger are applied to the pair of recesses V, and while holding the lighting fixture mounting device 10 so as to be pinched, the plug blade 11 is inserted into the hook-type ceiling wiring device and the fertilizer is turned, thereby turning the lighting fixture mounting device. 10 can be attached to a hanging ceiling wiring device. At this time, since the finger is settled in the concave portion V, it is easy to apply the fertility.
In the assembled state, the height at which the protrusion 2d of the second mounting member 2 projects from the upper surface of the first mounting member 1 is h1,
Assuming that the height of the flange portion 1c of the first mounting member 1 is h2, h
1 + h2 is designed to be equal to the difference in the projecting length of the hook ceiling and the hooking embedded rosette described below from the ceiling surface downward.

Next, a state in which the lighting fixture mounting apparatus 10 assembled as described above is mounted on a hook-type ceiling wiring device will be described. FIG. 5 is a side view showing a mounting state of the lighting fixture mounting device 10 when the hook-type ceiling wiring device is the hanging ceiling 31. The hooking ceiling 31 has a larger protruding length (that is, height) H1 downward from the ceiling 32 and a relatively smaller overall width W and overall length L as compared with the hooking embedded rosette. Both the total length L and the total width W are smaller than the inner diameter of a circle formed by the four protrusions 2d of the second mounting member 2. Therefore, the hooking ceiling 31
Even if the lighting fixture mounting device 10 is attached to the device, the protrusion 2d does not interfere anywhere. That is, the lighting fixture mounting device 10
Are mounted in the assembled state shown in FIG. An engaging portion (details will be described later) of the lighting fixture main body is held so as to ride on the upper surface of the flange portion 1c of the first mounting member 1. The distance between the upper surface of the flange portion 1c and the ceiling surface is Hc.

FIG. 6 is a side view showing the mounting state of the lighting fixture mounting device 10 when the hook-type ceiling wiring fixture is the hook-mounted embedded rosette 33. The hook-mounted embedded rosette 33 has a disk shape and, compared to the hook-sealing 31, has a ceiling 3.
2, and the diameter D is relatively large.
This diameter D is larger than the outer diameter of the circle formed by the four protrusions 2d. Therefore, when the lighting fixture mounting device 10 is to be mounted on the hooking embedded rosette 33, the projection 2
d always contacts the hooking embedded rosette 33. Projection 2
When the first mounting member 1 is further pushed up from a state where d is in contact with the hooking embedded rosette 33, the second mounting member 2 is relatively moved with respect to the first mounting member 1 against the spring 3 (FIG. 1). Descends. As a result, the projection 2d that has protruded from the upper surface 1a of the first mounting member 1 is retracted, and the luminaire main body is located between the flange 2c of the second mounting member 2 and the flange 1c of the first mounting member. There is a gap into which the engaging portion can enter. At this time, the distance Hr from the ceiling surface to the upper surface of the flange portion 2c is the difference between the protrusion length of the hooking ceiling 31 and the hooking embedded rosette 33 (H1-
H2) is a decreasing factor, but the difference dH in the height of the upper surfaces of the flanges 1c and 2c is an increasing factor. This difference dH is
It is equal to h1 + h2 described above. Therefore, the height difference dH is
This corresponds to the difference in the protrusion length of the hooking ceiling 31 and the hooking embedded rosette 33 from the ceiling surface. That is, dH = H1
-H2. Therefore, the increase factor and the decrease factor offset each other,
Eventually, the distance Hr = Hc.

FIGS. 7 and 8 show a lighting fixture main unit 4 attached to a lighting fixture mounting device 10 attached to a hook-type ceiling wiring fixture.
FIG. 7 is a cross-sectional view illustrating a state in which the hook-type ceiling wiring device is a hook-sealing 31; FIG. 8 is a cross-sectional view illustrating a state where the hook-type ceiling wiring device is a hook-embedded rosette 33; Each is shown. In FIG. 7, the lighting device main body 40 has a housing 41, a top plate 42 attached to an upper portion thereof, and a distal end portion tapered.
An engagement portion 44 urged inward from 1 by a spring 43
And The weight of the entire lighting fixture including the lighting fixture body 40 is applied to the engaging portion 44. Lighting fixture body 4
In order to attach the lighting fixture 0 to the lighting fixture mounting apparatus 10, the lighting fixture main body 40 is extrapolated from below from the state where the mounting of the lighting fixture mounting apparatus 10 shown in FIG. 5 is completed. Thereby, the engaging portion 4
4 abuts against the flange 2 c of the second mounting member 2 and retreats outward against the spring 43. In this way, as the lighting fixture main body 40 rises, the engaging portion 44 gets over the flange portion 2c, and subsequently gets over the flange portion 1c of the first mounting member 1. Here, the engaging portion 55 is engaged with the upper surface of the flange portion 1c. Thereby, the lighting fixture main body 40 is securely held by the lighting fixture mounting device 10. A gap Xc is formed between the ceiling surface of the ceiling 32 and the outermost top surface of the top plate portion 42, and a spacer 45 that is also used as an insect repellent is attached here.

On the other hand, as shown in FIG. 8, when the hook-type ceiling wiring device is the hook-mounted embedded rosette 33, the engaging portion 44 becomes the flange-like portion of the second mounting member 2 as the lighting device main body 40 rises. Get over 2c. Here, the engaging portion 55 is engaged with the upper surface of the flange portion 2c. Thereby, the lighting fixture main body 40 is securely held by the lighting fixture mounting device 10. As described above, the gap Xr formed between the ceiling surface of the ceiling 32 and the outermost top surface of the top plate portion 42 is, as described above, the hooking ceiling 31.
The distance Hc (FIG. 5) from the ceiling surface to the upper surface of the flange portion 1c in the case of (1) is substantially equal to the distance Hr from the ceiling surface to the upper surface of the flange portion 2c in the case of the hooking embedded rosette 33. 31 is substantially equal to the gap Xc. That is, irrespective of whether the hook type ceiling wiring device is the hook ceiling 31 or the hook embedded rosette 33, the gap between the top plate portion 42 and the ceiling surface is constant. Therefore, by providing a certain spacer or the like, the lighting fixture main body 40 can always be stably attached.

It should be noted that, in the present embodiment, the lighting fixture mounting device 10 is attached to the hooking ceiling and the hooking embedded rosette, but it is needless to say that the present invention can be applied to other types of hooking type ceiling wiring fixtures. . Further, if a similar supporting portion is provided in addition to the flange portions 1c and 2c, 3
It is possible to attach the lighting fixture in a fixed attachment state to the above-described hook-type ceiling wiring fixture. Further, it is also possible to use another elastic body instead of the spring 3 .

FIG. 9 is a perspective view showing a first mounting member and a second mounting member of a lighting fixture mounting apparatus according to a second embodiment of the present invention. In the present embodiment, a guide portion 1h that is recessed from the outer peripheral surface of the first attachment member 1 and extends downward is formed at the position of the notch 1f of the first attachment member 1 in the first embodiment. I have. As shown by the dashed line in the figure,
The notch 2i of the second mounting member 2 is formed with a predetermined size so as to allow the guide 1h of the first mounting member 1 to escape. Although not shown, also in the present embodiment, members similar to those of the holding plate 5 and the cover 6 in the first embodiment are provided, and a cutout portion adapted to the guide portion 1h is provided in these members. In the lighting fixture mounting apparatus of the second embodiment configured as described above, at the time of mounting, the worker can perform the mounting (or removing) operation by touching the entire surface of the finger to the guide portion 1h. Therefore, there is an advantage that operation is very easy. In addition, when the entire device is assembled, the inside of the device is prevented by the presence of the guide portion 1h.
It has the effect of preventing foreign substances from entering the interior. Other configurations and mounting operations are the same as those of the first embodiment.

FIG. 10 is a plan view showing a schematic external shape of the first mounting member 1 of the lighting fixture mounting apparatus according to the third embodiment of the present invention. In the present embodiment, parallel opposing flat operating portions 1i recessed from the outer periphery are provided at opposing positions on the outer periphery corresponding to the notches 1f in the first embodiment, and only the upper surface portion 1a is circular. is there. Although illustration is omitted, in this embodiment, members similar to the second mounting member, the holding plate 5 and the cover 6 in the first embodiment are provided, and they are compatible with the first mounting member 1. Needless to say, the shape is changed. In the lighting fixture mounting apparatus of the third embodiment configured as described above, at the time of mounting, the operator can perform the mounting (or removing) operation by touching the entire surface of the finger to the operation unit 1i. Moreover, since the operation unit 1i is relatively wide, a plurality of fingers can be applied. Therefore, there is an advantage that it is very easy to operate while having a simple configuration. Also, as in the second embodiment,
Since the inside is prevented from being exposed when the entire apparatus is assembled, there is an effect of preventing foreign substances from entering the inside.

FIG. 11 is a perspective view showing a first mounting member of a lighting fixture mounting apparatus according to a fourth embodiment of the present invention.
In the first mounting member 1 in the present embodiment, a plurality of tapered portions 1j are formed by chamfering the outer peripheral side of the lower end portion of the flange portion 1c for each small section. A non-tapered portion 1k that is not chamfered is interposed between adjacent tapered portions 1j. Other configurations are the same as those of the first embodiment. In the lighting fixture mounting apparatus according to the fourth embodiment configured as described above, even if the operator's finger touches the outer peripheral portion other than the notch portion 1f at the time of mounting, the first mounting member 1 is formed by the presence of the tapered portion 1j.
The finger meat is hardly caught between the first mounting member 2 and the second mounting member 2. Therefore, the mounting operation can be performed more safely. The configuration in which the tapered portion 1j is provided as in the present embodiment may be used in combination with the configurations in the second and third embodiments.

[0030]

The present invention configured as described above has the following effects. According to the lighting fixture mounting device of claim 1,
When the projection of the second mounting member abuts on the hook-type ceiling wiring device, the second mounting member is moved relative to the first mounting member by pressing the first mounting member against the elastic body from that state. And the supporting portion of the lighting fixture main body is changed based on this movement. Therefore, the difference in the projection length from the ceiling surface due to the type of the hook-type ceiling wiring device can be compensated for by changing the support portion, and the distance between the lighting fixture body and the ceiling surface can be kept substantially constant. This makes it possible to always and appropriately mount the lighting fixture body.

According to the lighting fixture mounting apparatus of the second aspect, the first mounting member is passed through the cutout portion without being disturbed by the second mounting member substantially below the first mounting member, and the fingertip is used. While pushing up, the operation of mounting the lighting fixture mounting device can be performed.

According to the lighting apparatus mounting apparatus of the third aspect, the operation of turning the lighting apparatus mounting apparatus can be performed while placing the finger on the notch and pushing up the first mounting member with the fingertip. The fixture mounting device can be easily attached to the hook-type ceiling wiring fixture.

According to the lighting fixture mounting apparatus of the present invention, the difference in the protruding length depending on the type of the hook-type ceiling wiring fixture can be offset with certainty by the difference in the height position of the supporting portion, so that the lighting fixture main body and the lighting fixture main body can be removed. The distance from the ceiling surface can be kept constant. Therefore, by providing a certain spacer between the lighting fixture main body and the ceiling surface, it is possible to reliably prevent rattling of the lighting fixture main body and to surely prevent insect invasion.
