2. Description of the Related Art In recent years, a sensor device having a detecting means for detecting a change in an irradiation field, for example, a change in brightness, has been manufactured separately from a lighting device, and this sensor device has been embedded and mounted on a ceiling wall of a building. There has been provided an illumination system in which a change in the brightness of an irradiation field is detected by a detection unit of the sensor device, and control such as turning on / off or dimming of the illumination device is performed based on the detection.

FIG. 14 shows the structure of a sensor device used in such a lighting system. The sensor device A includes a device main body 1 having an opening at a lower end, and the device main body 1 includes a housing portion 2 and a flange portion 3 horizontally extending outward from a periphery of the opening. In the housing part 2, as a sensor means, a PC board, an optical sensor 4 for detecting, for example, a change in brightness, a setting switch 5 for switching a detection operation time of the optical sensor 4, a detected brightness level, and the like. Is provided. The optical sensor 4 and the setting switch 5 are supported so as to be arranged on the opening surface at the lower end of the housing 2.

[0004] A cover panel 6 made of a light-transmitting synthetic resin is mounted below the instrument body 1, and the cover panel 6 covers an opening on the lower surface of the instrument body 1.

[0005] The peripheral portion of the flange portion 3 is
At a position separated by 0 °, a concave portion 10 is formed as an engagement receiving portion, as shown in FIG. Further, the cover panel 6 integrally has a peripheral side wall 6a which can be fitted to the outer periphery of the flange portion 3 at the peripheral edge, and engages with the concave portion 10 at a position 180 ° in the circumferential direction of the inner surface of the peripheral side wall 6a. Possible engaging claws 11 are formed integrally. These recesses 1
0 and the engaging claw 11 constitute an engaging means.

[0006] The outer side of the instrument body 1 is 180 ° in the circumferential direction.
At a distant position, a leaf spring 13 is mounted as mounting means. The pair of leaf springs 13 have their roots fixed to the opening side of the instrument body 1, and their free ends extend obliquely upward from the lower part of the instrument body 1 via bent portions 13 a bent in a V-shape. Is formed with a bent edge 13b which is bent in a hook shape.

[0007] B is a ceiling wall as a mounting portion to which the sensor device A is mounted.
4 are formed. When attaching the sensor device A to the ceiling wall B, first, the engaging claw 11 of the cover panel 6 is aligned with the concave portion 10 of the flange portion 3, and the cover panel 6 is fitted to the outer periphery of the flange portion 3. The cover panel 6 is attached to the flange 3 by engaging the claws 11 with the recesses 10 by their elastic deformation.

Next, the leaf springs 13 on both sides of the instrument main body 1 are pressed against the elastic force thereof along the peripheral wall of the accommodating section 2 to be pressed down, and the accommodating section 2 is attached to the ceiling wall B in this state. It is inserted into the hole 14 from below, and the hand is released from the leaf spring 13. Accordingly, the leaf springs 1 on both sides of the instrument body 1
3 is elastically expanded outward and inclined, and the inclined leaf spring 13 contacts the peripheral edge of the instrument mounting hole 14.

According to the above-described procedure, the instrument main body 1 is pulled upward by the elastic biasing force of the pair of leaf springs 13 that are going to spread. For this reason, the upper surface 3 ′ of the flange portion 3 is pressed against the lower surface B ′ of the ceiling wall B around the fixture mounting hole 14, and the fixture body 1 is embedded in the back side of the ceiling wall B by this pressure contact force. Supported by B.

Since the sensor device A having the above-described structure is embedded and mounted in a mounting portion such as a ceiling wall B, the mounting portion has a device mounting hole 14 having a size corresponding to the diameter of the sensor device A.
Need to be opened. Therefore, if it is not desired to make such a hole 14, it is necessary to take another mounting means for mounting the sensor device A.

Therefore, a device has been proposed in which the sensor device A is directly mounted on the mounting portion by using a direct mounting adapter shown in FIG. 13 instead of embedding the sensor device A in the mounting portion. The adapter 20 is formed of a metal adapter main body 21 having a rectangular box shape, and a spring receiving bracket 22 fixed inside the main body.

The adapter body 21 is provided with a power supply line through hole 23 and fixing holes 24 and 25 in a mounting wall 21a formed by an upper wall thereof. It is designed to be fixed to the ceiling wall through. On a front wall 21b formed by a lower wall of the adapter main body 21, a circular instrument mounting hole 26 having a size through which a portion other than the flange portion 3 of the sensor instrument A can be inserted is formed.

The spring receiving member 22 has a plate portion 22a which is welded to the rear surface of the front wall 21b and is located above the instrument mounting hole 26. A circular device mounting hole 27 having the same diameter as the device mounting hole 26 is formed in the plate portion 22a so as to face directly above the device mounting hole 26 so as to face each other. The spring receiving bracket 22 is provided to simulate the thickness of a ceiling wall as a mounting portion.

By using the adapter 20 having the above structure, the adapter main body 21 is fixed to the ceiling wall, and then the main body 21 and the tool mounting holes 26 of the spring receiving fitting 22 are fixed.
By inserting the pair of leaf springs 13 of the sensor device A into the contracted state into the sensor device 27, the sensor device A can be attached to the adapter 20 in the same manner as the attachment to the ceiling wall. Therefore, the sensor device A can be mounted on the ceiling wall via the adapter 20 without opening a large device mounting hole for embedding the sensor device A in the ceiling wall.

By the way, in the conventional sensor device A shown in FIG. 14, the length of the supporting leaf spring 13 is relatively short. For this reason, even when the sensor device A is embedded and mounted, or when the sensor device A is mounted on the ceiling wall B or the like via the adapter 20, a relatively large force is required when the leaf spring 13 is pressed down, and the sensor device A is mounted on the ceiling wall. Construction work when attaching to B becomes troublesome. As a remedy, when the strength of the leaf spring 13 is reduced, the force for fixing the sensor device A to the ceiling wall B is insufficient, and the possibility that the sensor device A is shifted below the ceiling wall B is increased. Moreover, the elastic deformation when the leaf spring 13 is compressed is limited by the free end of the leaf spring 13 hitting the vertical cylindrical surface of the housing portion 2, and usually the instrument mounting hole 14 or It is inserted into the instrument mounting holes 26, 27. That is, the pair of flattened leaf springs 13 are inserted into the instrument mounting holes 14 and the instrument mounting holes 26 and 27 in an inverted C-shape, and the bent edges 13a of these springs 13 are attached to the instrument mounting holes. Hole 14 and instrument mounting hole 26,
27 easily.

Further, the configuration of the adapter 20 requires a spring receiving plate 22 simulating the thickness of the ceiling wall.
The number of parts of the adapter 20 is large, and the cost is high. Moreover, even when the sensor device A is embedded and mounted on the ceiling wall, or when mounted on the ceiling wall via the adapter 20,
The attached sensor device A is not stopped. Therefore, if there is a dent or the like extending in the radial direction on the surface of the cover panel 6 and the mounting direction of the sensor device A is determined, the sensor device A naturally rotates after the mounting due to external vibration or the like. The orientation of the installation may change.

Further, in the sensor device A, as shown in FIG. 15, the upper surface 6a 'of the peripheral side wall 6a of the cover panel 6 detachably attached to the flange portion 3 and the flange portion 3
Is set to be at the same level as the upper surface 3 '. For this reason, when the upper surface 6a 'of the peripheral side wall 6a of the cover panel 6 is arranged at a higher level than the upper surface 3' of the flange portion 3 due to manufacturing variations or the like, the leaf spring 13 is used.
When the upper surface 3 'of the flange portion 3 comes into contact with the lower surface B' of the ceiling wall B, the cover panel 6 is pressed relatively downward by the elastic force. As a result, the pressing force causes stress on the engaging claws 11 of the cover panel 6, and the claws 11
And the cover panel 6 may fall off.

An instrument mounting hole 61 is formed in the bottom wall 52a of the second case 52, and a pair of spring receiving pieces 62 bent from the edge of the hole are integrally provided. The pair of spring receiving pieces 62 are separated from each other by 180 ° in the circumferential direction of the instrument mounting hole 61, and each project upward toward the mounting wall 51a. These spring receiving pieces 6
Numeral 2 is provided so as to simulate the thickness of the ceiling wall 34, and a concave portion 6 as shown in FIG.
3 are formed. The length of the recess 63 is the same as that of the leaf spring 36.
Greater than the width of.

The instrument mounting hole 61 is formed in such a size as to allow passage of a portion other than the flange portion 41 of the instrument main body 35 and prevent passage of the flange portion 41.
As shown in FIGS. 6 and 7, a pair of protrusion holes 61a is provided. Each of the spring receiving pieces 62 is erected from the edge at the back end of the protruding hole 61a. Therefore, the interval A between the bent base portions of the pair of opposing spring receiving pieces 62 is larger than the hole diameter B of the instrument mounting hole 61, and
As will be described later, when the sensor device 32 is attached to the adapter 33, the mutually parallel hole edges 61b of the protruding holes 61a and both side end surfaces 36d of the root side portion of the leaf spring 36 are close to each other (see FIG. 8). To face each other. or,
Based on the above configuration, as shown in FIGS. 6 to 8, a corner 65 protruding inside the hole diameter B is formed at the entrance of the protrusion hole 61 a.

Next, a procedure for mounting the direct-attached instrument device 31 having the above-described configuration on the ceiling wall 34 will be described.

First, a power line (not shown) drawn from behind the ceiling is passed through a power line through hole 55 of the first case 51.
The first case 51 is screwed to the lower surface of the ceiling wall 34. Next, the adapter 33 is assembled by combining the first case 51 with the second case 52, connecting the two via screws 53.

Thereafter, the sensor main body 35 of the sensor device 32 is inserted into the device mounting hole 61 of the adapter 33 together with the pair of leaf springs 36, and the sensor device 32 is mounted on the adapter 33. In this case, the leaf springs 36 on both sides of the instrument body 35
Are pressed against each other along the spring escape portion 43 of the instrument main body 35 against the elastic force thereof to be pressed down. That is, as shown by the two-dot chain line in FIG. It is elastically deformed as a fulcrum. In this state, while aligning the positions of the pair of spring receiving pieces 62 and the leaf springs 36, they are inserted into the instrument mounting holes 61 from below and released from the leaf springs 36. Then, the free end sides of the pair of leaf springs 36 are elastically expanded outward and separated so as to be separated from the instrument main body 35, and are inclined. 63 comes into contact with each other.

Next, the sensor device 32 is once lowered.
Thereby, the bent edge 36b of the leaf spring 36 is hooked on the concave portion 63, and the sensor device 32 is temporarily suspended. In this state, the electric connection between the power supply line already drawn into the adapter 33 and the sensor device 32 is performed. In this case, as described above, since the bent edge 36b of the leaf spring 36 is hooked on the concave portion 63, the hooking causes the sensor device 32 to rotate carelessly, and the leaf spring 36 comes off from the spring receiving piece 62. Is prevented. In other words, the temporary suspension state can be stably held, so that the connection work is easy.

Then, after this connection, the instrument body 35 is again
And a pair of leaf springs 36 is pushed up. By the above procedure,
As the pair of leaf springs 36 expand in an inverted C-shape due to their elastic force, the instrument body 35 is pulled up. Therefore, the upper surface 41a of the flange portion 41 is pressed against the lower surface of the bottom wall 52a around the device mounting hole 61, and the device main body 35 is mounted on the adapter 33 in a state in which the device main body 35 is embedded inside the adapter 33 by this pressing force. This mounting state is shown in FIGS.
Shown in In this way, the sensor device 3 via the adapter 33
2 can be attached to the ceiling wall 34, so that it is not necessary to make a large instrument mounting hole in the ceiling wall 34 unlike the case where the sensor instrument 32 is embedded and attached thereto.

As described above, the free ends of the pair of leaf springs 36 are compressed so as to approach each other, and the adapter 33 is pressed.
When the sensor body 32 and the leaf spring 36 are inserted into the device mounting hole 61 of the sensor body 32 and the sensor device 32 is mounted on the adapter 33 directly attached to the ceiling wall 34, the free end side is set to the spring at the upper end of the device body 35. It can be moved along the escape portion 43 and narrowed (see the state of the two-dot chain line in FIG. 3).
As a result, the free ends of the pair of leaf springs 36 are
5 is located inside the outer peripheral surface.

Therefore, the leaf spring 36 is connected to the instrument mounting hole 6.
Since it is less likely to be caught on the device 1, the pair of leaf springs 36 can be smoothly inserted into the device mounting hole 61 together with the device main body 35, and can be easily mounted on the sensor device 32.

In addition, since the spring relief 43 is provided at the upper end of the instrument main body 35 as described above, the two leaf springs 36 are formed to be long accordingly. The operating force for squeezing can be reduced. In addition, since the strength of the leaf spring 36 does not need to be reduced to reduce the operating force, the sensor device 32 is connected to the adapter 33.
And the sensor device 32 is prevented from being displaced below the adapter 33.

As described above, the leaf spring 36 having a long length is used.
Is deformed to a certain range, this leaf spring 36
Is supported in contact with the spring escape portion 43, so that there is no inconvenience that the leaf spring 36 is excessively deformed.

As described above, the sensor device 32 attached to the adapter 33 is pulled up by the elastic force of the leaf spring 36, and the upper surface 41a of the flange portion 41 is pressed against the bottom wall 52a of the adapter 33. In this state, as shown in FIG. 4, a margin S is generated between the bottom wall 52a and the end face 37c of the peripheral side wall 37a of the cover panel 37. For this reason, stress is not applied to the engagement claws 48 of the cover panel 37 even though the instrument body 35 is urged upward. Therefore, the engagement state between the engagement claws 48 of the cover panel 37 and the engagement recesses 42 of the flange portion 41 is always properly maintained, and the possibility of the cover panel 37 falling off is eliminated.

When the sensor device 32 is attached to the adapter 33, the root-side portions of the pair of leaf springs 36 are
The tool mounting hole 61 is housed in the protruding hole 61a, and the both end surfaces 37a of the root side portion are close to and opposed to the hole edge 61b of the hole 61a. for that reason,

When the instrument body 35 and the leaf spring 36 are inserted into the instrument mounting hole 71 and embedded in the ceiling wall 34 to mount the sensor instrument 32, the free end side has a spring relief formed by a tapered surface at the upper end of the instrument body 35. It can be moved along the part 43 and crushed (see the state of the two-dot chain line in FIG. 11). Thereby, the free ends of the pair of leaf springs 36 are located inside the outer peripheral surface of the instrument body 35.

Therefore, the leaf spring 36 is connected to the instrument mounting hole 7.
Since it is less likely that the sensor device 32 is caught by the sensor device 32, the sensor device 32 can be easily mounted by smoothly inserting the pair of leaf springs 36 together with the device main body 35 into the device mounting hole 71.

In addition, since the spring relief 43 is provided at the upper end of the instrument body 35 as described above, the two leaf springs 36 are formed to be long accordingly. The operating force for squeezing can be reduced. In addition, since the strength of the leaf spring 36 does not need to be reduced in order to reduce the operating force, the force for fixing the sensor device 32 to the hole of the device mounting hole 71 of the ceiling wall 34 does not become insufficient. Therefore, the sensor device 32 is prevented from being shifted below the ceiling wall 34.

c, a margin S is generated. For this reason, despite the fact that the instrument body 35 is urged upward, the cover panel 3
No stress is applied to the engaging claw 48 of FIG. Therefore, the engagement state between the engagement claws 48 of the cover panel 37 and the engagement recesses 42 of the flange portion 41 is always properly maintained, and the possibility of the cover panel 37 falling off is eliminated.

Therefore, the object of the present invention can be solved in the fourth embodiment as in the first embodiment.

The present invention is not limited to the above embodiments. For example, in the first embodiment, the screw 53 at the position corresponding to the free end of the leaf spring 36 (the screw 53 at the middle position in FIG. 1) is not used, or the screwing at the same position is eliminated. Or the first and second directions in a direction orthogonal to the direction connecting the pair of leaf springs 36.
The case bodies 51 and 52 may be screwed together to assemble the adapter 33. In such a configuration, since the interference between the screw 53 and the free end of the leaf spring 36 can be prevented, the height of the adapter 33 does not need to be particularly large in order to prevent the interference. Can be configured.
