Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture such as a ceiling-embedded type, a ceiling-mounted type, or a wall-mounted type, in which the body of the fixture is fixed to a mounting bolt protruding from the ceiling or the wall. Mounting device.

[0002]

2. Description of the Related Art For example, a ceiling-embedded type straight tube fluorescent lamp illuminator has a fixture main body fitted into an embedded hole opened in the ceiling, and a stabilizer or the like is attached to the fixture main body and a long length. A pair of sockets is attached to both ends in the direction, and a structure in which a straight tube fluorescent lamp is detachably supported over these sockets is formed.

When fixing such an instrument body to an embedded hole in a ceiling, conventionally, an attachment hole is formed in the instrument body, and an attachment bolt previously hung from the ceiling is inserted into the attachment hole, and a lower end of the bolt is attached to the attachment hole. A structure was adopted in which the fixture body was hung on the mounting bolts by screwing a fixing nut and tightening the fixing nut.

However, in the case of such a structure, in order to fix the instrument body to the mounting bolt, an operator supports the instrument body with both hands and inserts the mounting bolt into the attachment hole of the body, and in this state While supporting the main body with one hand, a washer is passed through the mounting bolt with the other hand, and a nut is screwed.

By the way, the weight of the instrument main body may reach several kilograms to several tens of kilograms. Therefore, in the above work, such a heavy instrument main body is lifted from the floor to the ceiling surface, and the one hand is used. Since it is necessary to support it with the other hand and insert the washer and the fixing nut into the mounting bolt with the other hand in this position, the work is heavy labor. In particular, until the fixing nut is screwed onto the bolt, it is necessary to support the heavy instrument main body with one hand for a long time, which requires a considerable amount of force, and thus has a drawback of poor work efficiency. In addition, when a large number of appliances such as a building are installed, fatigue is accumulated and there is a problem that construction time is long due to reduced efficiency.

For this reason, the conventional method, for example, FIG.
27 to 27, a mounting means has been proposed in which a daruma-shaped (gourd-shaped) mounting hole 151 is opened on the top surface of the instrument body 150. In this product, a washer 152 and a nut 153 are previously attached to a mounting bolt 131 hanging from a ceiling slab, and the mounting bolt 131 is passed through the large-diameter portion 151a of the daruma-shaped mounting hole 151 to attach the washer 152 and the nut 153 together. The device main body 150 is moved horizontally while the mounting bolt 131 is inserted, and the mounting bolt 131 is inserted into the small diameter portion 151b of the mounting hole 151.

In this way, the washer 152 and the nut 153 are caught by the small diameter portion 151b of the mounting hole 151, so that the instrument body 150 can be suspended and temporarily fixed to the mounting bolt 131. Nut 1 in this state
When 53 is tightened, the fixture body 150 is attached to the mounting bolt 131.
Fixed in place.

However, in the case of this structure, the instrument body 150 is lifted from below and the attachment bolt 131 is inserted into the attachment hole 151.
When introducing the mounting bolts 131, it is necessary to look for the mounting bolts 131 while looking through the mounting holes 151, but since the Daruma-shaped (gourd-shaped) mounting holes 151 cannot be opened so large, it is difficult to find the position of the mounting bolts 131. ,
Therefore, it takes time to insert the mounting bolt 131.

Further, in this device, after the mounting bolt 131 is inserted into the large diameter portion 151a of the mounting hole 151 of the device body 150, the device body 150 is horizontally moved in the arrow direction of FIGS. Mounting hole 15
It is necessary to enter the small-diameter portion 151b of No. 1. In the case of a ceiling-embedded lighting fixture, since the fixture main body 150 is fitted into the embedding hole 135 opened in the ceiling surface 130, the embedding hole 135 in the ceiling surface 130 is formed to be large in advance for the horizontal movement. You need to do it. As a result, when the instrument body 150 is moved horizontally, a gap is created in the embedding hole 135, which may be exposed. In order to prevent this, it is necessary to widen the flange 154 of the opening of the device body 150.

Further, the mounting bolt 131 hung from the ceiling slab or the like is not always accurately positioned, and therefore the mounting bolt 131 and the mounting hole 1
It is necessary to align 52 and 52, and in this case, it is necessary to move the instrument body 150 horizontally and adjust the position.
However, the above-mentioned Daruma-shaped (gourd-shaped) mounting hole 151 cannot be formed large because the nut 153 must be hooked on the small diameter portion 151b, and accordingly, the instrument body 150 can be freely moved horizontally. Position adjustment is difficult.

Further, in the case of such a structure, the nut 1
Since the structure for moving the screw 53 back and forth is required, it takes a lot of time to rotate the nut 153, resulting in a problem that working efficiency is not good.

On the other hand, another mounting means as shown in FIG. 28, for example, has been proposed. In this example, the instrument body 1
A large-diameter mounting hole 160 is opened on the top surface of the 50, and a washer 152 and a nut 153 are previously provided in the mounting hole 160.
The mounting bolt 131 to which is attached is inserted, and the temporary fixing large diameter washer 165 is hooked on the mounting bolt 131.

The large-diameter washer 165 for temporary fixing is used for the instrument body 15
0 has a larger diameter than the mounting hole 160 and is provided with a notch groove 166. The notch groove 166 is inserted into the mounting bolt 131 from the side, and the washer 152 and the nut 1 are inserted.
It is supposed to be supported by 53. Therefore, when the large-diameter washer 165 for temporary fastening is hooked on the mounting bolt 131 in the state shown in the drawing and the hand is released from the instrument main body 150, the main body 150 of the instrument is fixed via the large-sized washer 165 for temporary fastening.
It can be temporarily stopped. Therefore, when the nut 153 is tightened in this temporarily fixed state, the instrument body 150 can be fixed to the mounting bolt 131 at a predetermined height.

In this case, since the mounting hole 160 is relatively large, the mounting bolt 131 can be easily searched for, and the instrument body 150 can be horizontally moved within the range of this diameter, so that fine adjustment is possible. It will be possible.

However, since the above-described mounting structure is a structure in which the temporary fixing large-diameter washer 165, the washer 152, and the nut 153 are mounted on the mounting bolt 131, the number of parts is large and the nut 153 is screwed back and forth. Therefore, it takes a lot of time to rotate and tighten the nut 153 to remove or tighten the nut 153, resulting in a problem that work efficiency is not good.

An object of the present invention is to mount a lighting fixture in which the work efficiency of mounting the fixture is improved to reduce the burden on the operator, the number of parts is small, and the position of the fixture main body can be adjusted with respect to the mounting bolt. To get the equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention shown in FIGS.
A description will be given based on examples. The present embodiment shows a case where it is applied to a lighting device for a direct pipe type fluorescent lamp of a direct ceiling type,
In FIG. 1, reference numeral 1 is a main body of the apparatus, 20 is a straight tube fluorescent lamp, and 30 is a ceiling surface of a building as an attached portion.

The instrument main body 1 has a long shape in which a sheet metal is processed into an inverted U-shaped cross section, and is attached to the ceiling surface 30 with its opening facing downward. A lighting device 2a such as a ballast and a terminal block 2b are attached to the central portion of the instrument body 1 in the longitudinal direction, and socket attachments 3 and 3 are attached to both ends of the instrument body 1 in the longitudinal direction. The sockets 4 and 4 are attached to the socket mounts 3 and 3, respectively. A straight tube fluorescent lamp 20 is attached to these sockets 4, 4.

The straight tube fluorescent lamp 20 has bases 22 and 22 attached to both ends of a straight tube bulb 21, and base pins 23 protruding from the bases 22 and 22 are sockets 4,
Engage 4 Therefore, the straight tube fluorescent lamp 20 is detachably attached to the sockets 4 and 4 and is mechanically and electrically connected.

A reflector (not shown) is usually attached to the lower surface of the fixture body 1 between the fixture body 1 and the straight tube fluorescent lamp 20 so as to cover the ballast 2a and the like. Has become.

A structure for mounting the instrument body 1 on the ceiling surface 30 will be described. Mounting bolts 31, 31 are embedded in the foundation ceiling made of a slab of a building (not shown),
These mounting bolts 31, 31 penetrate the ceiling surface 30 and project downward.

Mounting holes 5 and 5 for inserting the mounting bolts 31 and 31 are formed in the top wall of the instrument body 1, and these mounting holes 5 and 5 are, for example, oblong holes or oval holes. In short, at least one of the opposing sides is in the shape of an elongated hole in parallel with each other. Thereby, the penetrating positions of the mounting bolts 31, 31 can be adjusted. As shown in FIG. 4, on the top wall of the instrument body 1, the contact projections 6 that contact the ceiling surface 30.
Are formed.

The instrument body 1 as described above is supported by the fasteners 10 and 10 attached to the attachment bolts 31 and 31, respectively. Next, the locking tools 10 and 10 will be described.

As shown in FIGS. 2 to 5, the locking tool 10 is made by cutting a metal strip into a predetermined shape and bending it into a predetermined shape. It has elastically deformable locking pieces 12, 12 which are bent and formed by extending downward from opposite edges of 11. The locking pieces 12, 12 are opposed to each other in a wedge shape, and are fitted into the mounting hole 5 of the instrument body 1 from above to below. Then, the locking edge 12 which these locking pieces 12, 12 have at the tip thereof.
“A” abuts against the threaded portion of the mounting bolt 31 from both sides in the radial direction, whereby the threaded portion can be locked.

An insertion hole 13 is formed in the central portion of the base portion 11 of the engaging member 10 so that the mounting bolt 31 can freely pass therethrough. The insertion hole 13 has an elongated shape along the longitudinal direction of the mounting hole 5 formed in the instrument body 1, and the mounting bolt 31 is movable in the longitudinal direction of the insertion hole 13.

Further, the base portion 11 of the locking device 10 has stop collars 14 ... Located at, for example, four corners thereof, and these stop collars 14 ... Has become. The elastically deformable support pieces 15 and 15 projecting outward are cut and raised on the side walls of the elastically deformable locking pieces 12 and 12.

When the locking pieces 12 and 12 are fitted into the mounting holes 5 of the instrument body 1, the supporting pieces 15 and 15 are elastically returned, and the tips of these supporting pieces 15 and 15 are on the lower surface of the instrument body 1 (mounting holes). The bottom surface of the hole edge 5) is abutted. In other words, the support edges 15, 15 and the stop collar 14 hold the edge of the mounting hole 5 of the instrument body 1 from above and below. As a result, the locking tool 10 is attached to the instrument body 1 and is provided slidably along the longitudinal direction of the attachment hole 5.

The operation of the first embodiment having such a structure will be described. The locking tools 10 and 10 are attached to the mounting bolts 31 and 31 that are penetrating through the ceiling surface 30 in advance. In this case, as shown in FIG. 2, the lower end of the mounting bolt 31 is introduced from the insertion hole 13 formed in the base portion 11 of the locking tool 10,
The lower end of the mounting bolt 31 is inserted between the locking edges 12a of the locking pieces 12 and 12 while pushing the locking edges 12a of the locking pieces 12 and 12 apart with the lower ends of the mounting bolts 31.
Then, the locking pieces 12 and 12 are elastically restored, and the locking edges 12a of the locking pieces 12 and 12 elastically sandwich the mounting bolt 31 from both sides in the radial direction thereof, and abut the threaded portion of the bolt 31 to form a screw thread. Lock on. Therefore, it is possible to attach the fasteners 10 and 10 only by pushing them into the lower ends of the mounting bolts 31 and 31.

In this state, the instrument main body 1 is lifted up, and the fittings 10, 5 are attached to the mounting holes 5, 5 opened on the upper surface of the instrument main body 1.
Insert 10. In this case, when the locking pieces 12 and 12 of the locking tools 10 and 10 are fitted into the mounting holes 5 and 5, first, the elastically deformable support pieces 15 and 15 are formed at the opposite hole edges of the mounting hole 5. When the support pieces 15 and 15 are pushed and retracted, and the support pieces 15 and 15 exceed the thickness of the instrument body 1 and pass to the lower surface side, the support pieces 15 and 15 elastically return to the original shape. Therefore, the support piece 1
The upper wall of the instrument body 1 is clamped by 5, 15 and the stop collar 14 of the base portion 11.

For this reason, the instrument body 1 is provided with these locking tools 1
It is suspended from the lower ends of the mounting bolts 31 and 31 via 0 and 10, and even if the supporting force by the worker is released, the mounting bolts 31,
Supported by 31.

When the instrument main body 1 is pushed up in this state, the locking pieces 12 of the locking tools 10 and 10 slide the locking edges 12a of the locking bolts 12 onto the threaded portions of the mounting bolts 31 and are mounted successively over the screw threads. Ascend along the bolt 31. Then, when the contact projections 6 formed on the upper surface wall of the instrument body 1 come into contact with the ceiling surface 30, the pushing up of the instrument body 1 is stopped, and in this state, the locking pieces 12, 12 of the locking tools 10, 10. Locking edge 12 a of the mounting bolt 31 is locked to the thread of the mounting bolt 31, so that the instrument body 1 is secured to the mounting bolts 31, 31 via the locking tools 10, 10.
It can be fixed to and attached directly to the ceiling surface 30.

According to such a lighting fixture mounting device,
The fixtures 10 and 10 are attached to the mounting bolts 31 and 31 in advance, the device body 1 is lifted, and the fixtures 10 and 10 are fitted into the mounting holes 5 and 5, respectively. 1 can be temporarily fixed to the mounting bolts 31, 31. Therefore, the temporary fixing work is easy and can be performed in a short time, and it is not necessary to support the heavy instrument main body 1 for a long time.

After such temporary fixing, the instrument body 1 can be fixed at a predetermined position by pushing up the instrument body 1 and raising the contact projections 6 ... . That is, the final fixing is possible by simply pushing up the instrument body 1.

Therefore, since a nut or the like is not used, a laborious work such as a rotating operation is not required, and the mounting work of the instrument main body 1 can be carried out very easily, and it can be quickly carried out without requiring a great labor. . As a result, it is possible to significantly reduce the burden on the contractor who installs the equipment.

Moreover, the mounting bolts 31 and 31 and the locking tool 1
Since the instrument body 1 can be fixed only by 0, 10, the number of parts can be small.

Further, in the above-mentioned structure, the locking tool 10 attached to the mounting hole 5 sandwiches the instrument body 1 with the support piece 15 and the stop collar 14 in the direction of arrow A (the instrument body 1 and the mounting hole 5). Since it can be moved in the longitudinal direction), even if the projecting position of the mounting bolt 31 varies in advance, the locking tool 1
By shifting 0 along the mounting hole 5 in the direction of the arrow A, the engagement of the locking tool 10 can be reliably maintained, and therefore the mounting position can be adjusted. In this case, the tool body 1 can be displaced in the direction of arrow A if there is a margin around it, or conversely, only the locking tool 10 can be displaced in the direction of arrow A without moving the instrument body 1, and the position can be changed. Easy to adjust.

In order to make the locking member 10 movable in the mounting hole 5 in the direction of the arrow A as described above, it is necessary to form the mounting hole 5 in a relatively large size. For example, it becomes easy to look for the mounting bolt 31 from the bottom, and the work of aligning the mounting hole 5 with the mounting bolt 31 can be performed easily and quickly.

Moreover, even if the mounting hole 5 having such a large opening is formed, since the lower surface of the instrument body 1 is covered with a reflection plate (not shown), the mounting hole 5 is hidden and the appearance is impaired. Absent. Further, since the locking tools 10 and 10 are also hidden by the reflecting plate, the appearance is not deteriorated.

In the case of the first embodiment, the locking tool 10 is previously locked to the mounting bolt 31 and the instrument body 1 is temporarily fixed to the locking tool 10. Differently, the locking tool 10 is previously attached to the mounting hole 5 of the device body 1, and in this state, the device body 1 is lifted and the locking tool 1
0 may be locked to the mounting bolt 31.

6 to 10 show a second embodiment of the present invention which can achieve the objects of the present invention. In this second embodiment,
This is a case where it is applied to a ceiling-embedded lighting fixture, and the first embodiment is an example in which the locking device 10 is attached to the mounting hole 5 of the fixture body 1 so that its position can be adjusted relatively in the direction of arrow A. On the other hand, it differs from the first embodiment in that the locking tool 10 is provided so that the position can be adjusted in the arrow A direction and the arrow B direction orthogonal thereto. Since the configuration other than these points is the same as that of the lighting fixture mounting apparatus according to the first embodiment, the same components are designated by the same reference numerals as those in the first embodiment, and the description of the configuration will be given. Although the same actions and effects based thereon are omitted, these same components also constitute a part of the configuration of the apparatus of this embodiment. The configuration different from that of the first embodiment will be described below.

Since the ceiling-embedded fixture main body 40 of the ceiling-embedded lighting fixture according to the second embodiment is fitted into the embedding hole 35 opened in the ceiling surface 30, the embedding hole 35 is formed.
Since there is no room to shift the position in the horizontal direction inside, it is desirable to adjust the position of the locking tool 10 in the direction of arrow A and the direction of arrow B orthogonal thereto. Therefore, in this embodiment, the following structure is adopted.

That is, in the mounting hole 5 formed in the upper surface of the instrument body 40, guide walls 41 facing each other, which are bent downward at right angles along the edge of the hole extending in the longitudinal direction,
41 are formed. Further, in the present embodiment, the adjusting tool 45 is used which holds the guide walls 41, 41 from below and is slidable along the guide walls 41, 41.

The adjusting tool 45 is made of sheet metal and has a through hole 46 formed in the center thereof. The locking tool 10 having the same structure as the locking tool used in the first embodiment is attached to the through hole 46. The through hole 46 is a long hole in the direction orthogonal to the longitudinal direction of the attachment hole 5 formed in the instrument body 40, for example, a rectangular shape or an oval shape. The locking tool 10 attached to the through hole 46 is slidable in the direction of arrow A along the longitudinal direction of the through hole 46, as in the case of the first embodiment. Each part of the locking tool 10 is given the same reference numeral as the locking tool of the first embodiment.

The adjusting tool 45 includes guide walls 41, 41.
Sliding walls 47, 47 that slide along are formed upright.

Therefore, in the case of the second embodiment having such a configuration, the locking tool 10 is attached to the adjusting tool 45, and the adjusting tool 45 is attached to the guide wall 41 of the mounting hole 5 from the lower surface side of the tool body 40. The device main body 40 is lifted in this state. Then, the tool body 40 is fitted into the embedding hole 35 formed in the ceiling surface 30, and the locking tool 10 mounted on the adjusting tool 45 is locked to the mounting bolt 31. Then, the adjusting tool 45 is supported by the mounting bolt 31 via the locking tool 10, and the adjusting tool 45 supports the instrument main body 40, so that the instrument main body 40 is eventually hung from the mounting bolt 31.

In this state, the adjusting tool 45 is further pushed up, and the flange portion 48 formed on the opening edge of the instrument body 40 is fixed to the ceiling surface 3.
When it touches 0, it stops pushing up. As a result, as shown in FIGS. 9 and 10, the device body 40 is fixed in a state of being fitted in the embedding hole 35.

In the second embodiment, the locking tool 10 is attached to the through hole 46 formed in the adjusting tool 45 and is slidable in the direction of arrow A along the longitudinal direction of the through hole 46. In this adjusting tool 45, since the slide walls 47, 47 formed by standing up and down on the left and right are slidable in the arrow B direction along the guide walls 41, 41 provided with the mounting holes 5 of the instrument body 40, the locking is eventually achieved. The tool 10 can be adjusted in position in the directions of arrows A and B with respect to the tool body 40. Therefore, the instrument body 40 can be moved relative to the mounting bolt 31 in the directions of arrows A and B.

For this reason, even if the fixture body 40 is immovable in the horizontal direction because it is fitted in the embedding hole 35 of the ceiling surface 30, the locking tool 10 is movable in the directions of arrows A and B. The position of the locking tool 10 can be easily adjusted and aligned against variations in the position of the bolt 31, and reliable locking is possible.

11 to 15 show a third embodiment of the present invention which can achieve the object of the present invention. In the third embodiment, in order to further improve the mounting reliability of the fixture body 40 to the mounted portion (ceiling surface 30) in the ceiling-embedded lighting fixture, the through hole 46 of the adjusting tool 45 is formed as follows. It is different from the second embodiment in that it is configured and that the locking tool 10 has a shape maintaining structure. Since the configuration other than these points is the same as that of the lighting fixture mounting apparatus according to the second embodiment, the same components are designated by the same reference numerals as those in the second embodiment, and the description of the configuration will be given. Although the same actions and effects based thereon are omitted, these same components also constitute a part of the configuration of the apparatus of this embodiment. The configuration different from that of the second embodiment will be described below.

The through-hole 46 in the ceiling-embedded luminaire according to the second embodiment will be described. The through-hole 46 extends from the hole edge extending in the longitudinal direction and facing each other to the inside of the through-hole 46. The locking projections 46a that are projected are provided so as to respectively project.

To attach the locking tool 10 to the adjusting tool 45 having the through hole 46 having such a structure, the locking tool 10 may be fitted into the through hole 46 so as to pass from the upper side to the lower side. . Then, first, the elastically deformable support piece 15,
When the support pieces 15 and 15 pass through the lower surface side beyond the plate thickness of the instrument main body 40, the support pieces 15 and 15 are elastically restored to their original positions. Thus, it projects and is caught on the lower surface of the hole edge of the through hole 46. Therefore, the support pieces 15, 15 and the base portion 1
The upper wall of the instrument body 40 is clamped by the stop collar 14 of FIG.

In this case, since the through hole 46 has the locking projections 46a, 46a protruding from the edge of the hole, the support pieces 15, 15 of the locking tool 10 for supporting the instrument body 40 on the mounting bolt 31. It is possible to secure a large margin for hanging the through hole 46 to the hole edge. Therefore, irrespective of variations in the manufacturing dimensions of the locking tool 10, there is no risk that the support body 15, 15 will be reliably hooked to the hole edge of the through hole 46 and the tool body 40 will fall, and the mounting reliability of the tool body 40 will be reduced. It is desirable that the protrusion width H of the locking convex portion 46a that can improve the above-mentioned value is 2 to 3 mm.
This is because if it is more than that, the elastic deformation amount of the support pieces 15, 15 becomes too large, and an excessive operation force is required for fitting the locking tool 10 into the through hole 46, which is prevented. The operability of attaching the locking tool 10 to the adjusting tool 45 is secured, and below that, the through holes 46 of the support pieces 15, 15 are provided.
This is because the margin of contact with the hole edge becomes smaller than the necessary and sufficient value, and the mounting reliability tends to deteriorate.

Further, the shape maintaining structure of the locking tools 10 and 10 will be described. Contact ends 12b and 12b, which come into contact with each other in surface contact with each other, are formed at the tips of the pair of locking pieces 12 and 12 provided in the locking tools 10 and 10, respectively, and the locking tool 10 in its free state. The elastic force of the locking pieces 12, 12 allows the contact ends 12b, 12b to maintain contact. Moreover, one abutting end 12a has a cover portion 12b1 that covers the tip of the other abutting end 12b, so that the abutting end 12b, which is used when the fastener 10 is handled,
The injury of the worker due to the edge of the tip 12b is prevented.

By the way, the locking pieces 12, 12 provided on the locking tool 10 by bending have large variations in bending. However, as described above, since the engaging pieces 12, 12 are provided with the contact ends 12b, 12b that contact each other by their elastic force, the shape of the engaging tool 10 can be maintained in a predetermined state. Therefore, the gap between the locking edges 12a does not become abnormally narrow or disappears due to the variation, and a gap of a predetermined width can be secured between the locking edges 12a, 12a. Attach the locking tool 10 to the mounting bolt 31
The mounting bolt 31 can be easily passed through the gap when it is mounted on, and thus the locking tool 10 can be easily mounted on the mounting bolt 31.

The through hole 4 adopted in the third embodiment is used.
The structure 6 can be applied to the mounting hole 5 of the first embodiment. In this case, the locking projections that project inside the mounting hole 5 may be provided so as to project at the edge of the mounting hole 5 along the arrow A direction. Further, the contact end portions 12b and 12b used in the third embodiment can be applied to the locking portion 10 of the first and second embodiments.

16 to 24 show a fourth embodiment of the present invention which can achieve the objects of the present invention. The fourth embodiment is an example of a ceiling-embedded lighting fixture in which the locking device 10 is attached to the fixture main body 40 so that the position of the fixture 10 can be adjusted in both directions A and B. On the other hand, in that the locking tool 10 is provided so that the position can be adjusted only in the arrow A direction,
This is different from the third embodiment. Since the configuration other than these points is the same as that of the lighting fixture mounting apparatus according to the third embodiment, the same components are designated by the same reference numerals as those in the third embodiment, and the description of the configuration will be given. Although the same actions and effects based thereon are omitted, these same components also constitute a part of the configuration of the apparatus of this embodiment. The configuration different from that of the third embodiment will be described below.

That is, in order to further improve the mounting reliability of the instrument body 40, the through-holes 46 formed by projecting the locking projections 46a extending in the longitudinal direction and projecting inward from the opposite hole edges. The length E in the longitudinal direction is set to be slightly larger than the length F between the stop collars 14, 14 that are opposed to each other in the longitudinal direction of the base portion 11 of the locking tool 10. This limits the position of the locking device 10 in the direction of arrow B shown in the third embodiment so that it cannot be adjusted. Moreover, by shortening the through-hole 46 in this way, the longitudinal ends of the base portion 11 (including the pair of stop flanges 14 corresponding to the width direction of the base portion 11) of the locking tool 10 are locked. The locking tool 10 is attached to the adjusting tool 45 by sandwiching the hole edge of the through hole 46 between the pieces 15 and 15 from above and below.

Further, the through hole 4 adopted in the fourth embodiment.
The structure 6 is also applicable to the mounting holes 5 of the first to third embodiments.

In each of the above-described embodiments, the case of the ceiling-mounted lighting fixture and the ceiling-embedded lighting fixture has been described, but the present invention is not limited to these embodiments, and a wall-mounted lighting fixture or the like can be used. Even if it exists, it can be implemented, and the luminaire is not limited to the luminaire for the straight tube fluorescent lamp.

[0066]

As described above, according to the first aspect of the present invention, since the engaging member attached to the instrument body is engaged with the thread of the attaching bolt by the opposing engaging piece, the engaging member is rotated with respect to the attaching bolt. The operation body is locked without any operation, so that the tool body can be engaged with the mounting bolt with one touch through the locking tool. Therefore, the operator is freed from the work of manually supporting the instrument body. Moreover, since the locking tool can slide in one direction along the mounting hole of the instrument body, it is easy to adjust the position with respect to the mounting bolt. Furthermore, this product requires a small number of parts.

According to the invention of claim 2, the adjusting tool is attached to the instrument body so as to be slidable in one direction, and the locking tool is orthogonal to the one direction with respect to the adjusting tool. Since it is slidably attached in any direction, the locking device can be adjusted in any position in the horizontal direction of the instrument body.
Positioning of the locking tool with respect to the mounting bolt becomes easy.

According to the third aspect of the present invention, the engagement margin of the locking tool attached to the mounting hole of the instrument body or the through hole of the adjusting tool can be increased to the edge of the hole. It is possible to improve the reliability of attachment of the instrument body to the attached portion regardless of variations in the size of the fastener.
