[Lock mechanism 5]
A plurality (two in the present embodiment) of the locking mechanisms 5 are provided on the upper surface of the lower plate 24c in the space K described above (that is, the inner surface of the wall of the housing 2) with a predetermined interval in the left-right direction. In order to prevent the opening operation of the lid 3 by engaging with the engaging portion 4 of the lid 3, the following configuration is provided.

  As shown in FIGS. 1 and 4, the lock mechanism 5 is mounted on the upper surface of the lower plate 24 c of the outer frame member 24 (the inner surface of the wall of the housing 2), and is supported by the plate base 33. A substantially rectangular locking plate 6 that locks with the locking portion 4 of the lid 3, a support pin 34 that loosely fits in a pin hole 6 c of the locking plate 6, and a locking pin 34 that is locked by the support pin 34. The urging means 35 that urges the plate 6 in the direction approaching the lower side (the inner surface of the wall of the housing 2) and the through-hole 9 in the wall (the plate base 33 and the lower plate 24c) of the housing 2 are freely retractable. And a bit member 8 whose lower end is exposed to the outside.

By this lock mechanism 5, the lid 3 is held in a state where the lower end portion is locked and closed by the outer frame member 24, and the bit member 8 is pushed in from the outside of the lower surface of the wall of the housing 2, thereby The locking plate 6 rises against the urging force, the locking between the locking plate 6 and the locking portion 4 is released, and the lid 3 can be opened upward.
[Plate base 33, locking plate 6, bit member 8, etc.]
The plate base 33 is a substantially rectangular parallelepiped member attached to the upper surface of the lower plate 24c so that the longitudinal direction is along the front and rear, and a wide groove 33a into which the locking plate 6 can be fitted is formed on the upper surface. ing. A screw-engagement hole 33b in which a female screw is cut to screw the support pin 34 is provided in the approximate center of the bottom surface of the groove 33a. The through hole 9 (strictly, a part of the through hole 9) is formed (see FIG. 4).

The through hole 9 is provided with a small hole diameter portion 9a whose lower portion (portion close to the lower plate 24c) is smaller in diameter than the upper portion, and a hole step between the small hole diameter portion 9a and the upper portion (large hole diameter portion 9b). 9c is formed.
The lower plate 24c is provided with a communication hole 37 that communicates with the small hole diameter portion 9a when the plate pedestal 33 is attached. The following is provided on the wall of the housing 2 including the communication hole 37. The through-hole 9 is defined.

The plate base 33 is provided with a thin plate-like leg portion 33c that protrudes outward in the front-rear direction from the lower part of the front-rear surface. The protruding ends of the front and rear leg portions 33c abut against the front and rear inner surfaces of the lower pedestal portion 31b, thereby preventing the plate pedestal 33 from shifting due to the unlocking operation (see FIG. 1).
The locking protrusion 4a of the locking portion 4 passes through the entry hole 36 provided in the lower pedestal portion 31b and enters the upper portion of the leg portion 33c of the plate pedestal 33 in the space K (lower pedestal portion 31b). Come.

As shown in FIGS. 1 and 4, the locking plate 6 is a horizontally long plate disposed so that its longitudinal direction is along the front and rear.
A flange portion 6a is formed extending downward from the front and rear ends of the locking plate 6 (on the inner side of the wall of the housing 2). The extending width of the flange portion 6a is such that when the locking plate 6 comes into contact with the bottom surface of the groove 33a, the locking groove of the locking protrusion 4a that has entered the entry hole 36 of the lower pedestal portion 31b with the lid 3 closed. 4b is set to such a length that the hook 6a can be locked.

Further, the length of the locking plate 6 (the distance between the front and rear flanges 6a) can be locked simultaneously with the locking portions 4 of the front and rear lids 3 when the locking plate 6 is in contact with the bottom surface of the groove 33a. Thus, the locking plate 6 is set so as to be spanned between the front and rear locking portions 4 as much as possible.
As a result, the two lids 3 supported by the housing 2 can be blocked by the single locking mechanism 5 (locking plate 6) to prevent the opening operation, and the housing lid stopper 1 can be reduced in size and structure. Can be simplified.

In addition, the front and rear outer sides of the front end of the flange portion 6a are chamfered, and the chamfered portion 6b facilitates entry of the tapered locking protrusion 4a to a position where it is locked with the flange portion 6a.
A pin hole 6c penetrating in the plate thickness direction is formed in the approximate center of the locking plate 6. The diameter of the pin hole 6c is set to be slightly larger than the diameter of the support pin 34.
The support pin 34 includes a flange-shaped head portion 34a, and a male screw portion 34b is formed from a midway portion to a lower portion in the pin axis direction.

Therefore, by screwing the male threaded portion 34b into the screwing hole 33b of the plate base 33, the support pin 34 stands up from the bottom surface of the groove 33a of the plate base 33, and the head portion 34a of the support pin 34 extends from the bottom surface of the groove 33a. It is located at a predetermined height L (head height L).
The biasing means 35 is a coiled compression spring 35 (pressing spring), and the inner diameter thereof is larger than the support pin 34 and the pin hole 6c of the locking plate 6, and the head of the support pin 34 It is formed smaller than the diameter of 34a.

The length of the compression spring 35 is a natural length that is not compressed and is longer than the head height L. Therefore, if the compression spring 35 and the locking plate 6 are loosely fitted to the support pin 34 and the male thread portion 34b of the support pin 34 is screwed into the screwing hole 33b of the plate base 33, the locking plate 6 is always provided. The peripheral portion of the pin hole 6c is pressed (biased) downward (in the direction approaching the wall inner surface of the housing 2).
Due to the downward biasing by the compression spring 35, the locking plate 6 comes into contact with the bottom surface of the groove 33a, and the flanges 6a of the locking plate 6 are simultaneously locked to the front and rear locking portions 4.

As described above, the locking plate 6 is configured so as to be close along the wall inner surface side of the housing 2 at the time of locking and to be unlocked with a minimum separation. If the proximity / separation distance can be ensured, the lock mechanism 5 can be built in the existing lower pedestal portion 31b (space K), and space saving can be achieved in the housing 2.
Further, the compression spring 35 presses only the peripheral part (that is, the substantially central part) of the pin hole 6 c of the locking plate 6, and the pin hole 6 c is loosely fitted in a state where a gap is formed with the support pin 34. Yes.

Therefore, the locking plate 6 can be inclined with respect to the bottom surface of the groove 33a (the wall inner surface of the housing 2) on the plate base 33. That is, only the front and rear ends of the locking plate 6 are grooves. 33a can be lifted away from the bottom surface.
As shown in FIGS. 1 and 3, the bit member 8 includes a substantially cylindrical body portion 8a, a tapered contact portion 8b provided on one end side of the body portion 8a, and the body portion 8a. A bit diameter small portion 8c having a diameter smaller than that of the body portion 8a provided on the end side is provided. A bit step 8d is formed between the small bit diameter portion 8c and the body portion 8a.

The bit member 8 is formed such that the body portion 8a is slightly smaller in diameter than the large hole diameter portion 9b of the through hole 9, and the small bit diameter portion 8c is slightly smaller in diameter than the small hole diameter portion 9a and the communication hole 37. 9 can slide in and out freely.
The bit member 8 has a length of the body portion 8 a that is substantially the same as the large hole diameter portion 9 b of the through-hole 9, and a small bit diameter portion 8 c has a total hole length of the small hole diameter portion 9 a and the communication hole 37. It is formed longer than the length.

Therefore, as shown by the solid line in FIG. 1, when the bit step 8 d is locked to the hole step 9 c of the through hole 9, the bit member 8 has the tip of the contact portion 8 b at the groove 33 a of the plate base 33. It is substantially in contact with the lower surface of the locking plate 6 that is located at substantially the same height as the bottom surface and is biased downward (the surface on the side close to the wall inner surface of the housing 2).
Further, since the bit step 8d is locked to the hole step 9c, the bit member 8 is prevented from being pulled out from the through hole 9. Further, when the bit step 8d is engaged with the hole step 9c, the bit diameter small portion 8c of the bit member 8 protrudes outward from the lower surface of the lower plate 24c (the outer wall surface of the housing 2).

Therefore, as shown by the phantom line in FIG. 1, the bit member 8 is retracted into the through hole 9 by pushing the protruding small portion 8c against the urging force of the compression spring 35, and the contact portion 8b is By pressing the lower surface of the locking plate 6, the locking plate 6 can be separated from the plate base 33 (the wall inner surface of the housing 2).
Due to the separation of the locking plate 6, the locking of the hook portion 6 a of the locking plate 6 and the locking portion 4 of the lid 3 is released, and the lid 3 can be opened (see the phantom line in FIG. 1). .

On the other hand, since the locking plate 6 is biased downward by the compression spring 35, when the bit diameter small portion 8c is released, the bit member 8 moves downward in the through hole 9 (on the outer wall side of the housing 2). And the small bit diameter portion 8c again protrudes outward from the lower surface of the lower plate 24c.
As a result, the lock mechanism 5 provided in the housing 2 can be released (opening the lid 3) from the outer wall surface of the housing 2, and the bit can be operated without exposing all of the housing lid stopper 1 to the outside. Since only the small-diameter portion 8c is required to protrude, the bulge on the outer wall surface of the housing 2 can be minimized and the appearance of the housing 2 can be improved.
[Unlocking either front or back]
FIG. 3 shows that the small-diameter portion 8c of the bit member 8 protrudes in two places in the front-rear direction because the through-hole 9 is provided in the front-rear direction with the support pin 34 interposed therebetween as described above. ing.

At this time, if any one of the front and rear bit diameter small portions 8c is pushed in, the end of the pushed-in locking plate 6 is lifted up, that is, the locking plate 6 is the bottom surface of the groove 33a of the plate base 33 (housing 2). The inner surface of the wall is inclined in the front-rear direction.
Therefore, when the locking plate 6 is tilted and separated, only the collar portion 6a on the cantilevered side of the front and rear end portions of the locking plate 6 releases the locking with the locking portion 4 of the lid 3 on the same side. It becomes possible.

In addition to this, if both the front and rear bit diameter small portions 8c are pushed in at once, the locking plate 6 moves upward (mainly parallel to the bottom surface of the groove 33a of the plate base 33) (housing). 2). In this case, the locking between the locking plate 6 and the front and rear locking portions 4 can be simultaneously released.
Therefore, the unlocking can be easily performed according to the necessity of the opening operation of the front and rear lid 3.

The two sets of bit members 8 and through holes 9 constitute separation means 7 that separates the locking plate 6 from the plate base 33.
[Usage Mode of Case Lid Stopper 1]
A usage mode of the housing lid stopper 1 shown in FIGS. 1 to 4 will be described.
When replacing parts such as the light source 10 inside the housing 2 or performing repair work on the light emitting device 21 that has already been installed, the installation position of the housing 2 itself (ceiling T such as a station building or building) Depending on the size of the part to be replaced, it is necessary to open either the front or rear lid 3.

Therefore, the operator pushes in the bit member 8 on the side of the lid 3 to be opened, and releases the locking between the locking plate 6 and the locking portion 4.
In addition, the light emitting device 21 such as a guidance display or a signboard is mostly attached at a high position so as to catch the eye, but even if the worker performs a work with a stepladder or the like, the light emitting device 21 is outside the housing 2. Since the lock of the lid 3 can be released simply by pushing the protruding bit diameter small portion 8c, the operation can be performed very easily.

Further, since only the small bit diameter portion 8c of the lock mechanism 5 protrudes to the outside, the cords and clothes are prevented from being caught during the work, and the conspicuous lower surface of the housing 2 has a clean design.
After the replacement of the light source 10 of the light emitting device 21 and the like is completed, a current is supplied to the light source 10 to illuminate the light emitting surface 23, so that a guidance display, an advertising matter, etc. are raised to attract attention.
[ Reference form]
Next, a reference form of the housing lid stopper 1 will be described.

FIG 5, the light emitting device 21 is shown having a reference embodiment der Ru housing lid stopper 1.
The most different point of the case lid stopper 1 according to the reference embodiment from the first embodiment is that the lid 3 is provided only on the front surface (one side) of the housing 2.
Thus, locking plate 6, the front side of the hook 6a is interlocked with the locking groove 4b of the engaging portion 4, and thus to prevent the opening of the operation the lid 3 on the front side.

In FIG. 5, the locking plate 6 is also provided with the flange portion 6 a on the rear side, and the bit member 8 and the through hole 9 are also provided on the rear side of the support pin 34, but these may be omitted. .
Further, the light emitting device 21 has the rear surface side of the housing 2 without the lid 3 attached to the wall surface W, and the attachment member 22 is not provided on the upper plate 24 a of the outer frame member 24.
Other functions and effects are substantially the same as those of the first embodiment.

The present invention is not limited to the embodiment described above. Each configuration of the case lid stopper 1 or the like, or the overall structure, shape, dimensions, and the like can be appropriately changed in accordance with the spirit of the present invention.
The case lid stopper 1 stops the lid 3 of the housing 2 of the light emitting device 21, but may be used to stop the lid 3 of the sealing case 2 such as a switchboard or cubicle.
The housing 2 may not be formed in a substantially rectangular parallelepiped shape but may be a substantially cylindrical shape.

The lock mechanism 5 exposes the end of the bit member 8 that presses the locking plate 6 to the outside. However, if the locking mechanism 5 can release the locking with the locking portion 4 from the wall outer surface side of the housing 2, Any configuration may be employed such that a part of the stop plate 6 is exposed to the outside, or the locking plate 6 and the bit member 8 are integrated.
The locking plate 6 is urged in a direction approaching the wall inner surface of the housing 2, but conversely, the locking plate 6 may be urged in a direction away from the wall inner surface of the housing 2. In this case, the flange portion 6a of the locking plate 6 extends upward, and the locking groove 4b of the locking projection 4a is formed in a downward opening shape.

Further, the locking plate 6 may be longer than the front-rear width of the lower plate 24c of the outer frame member 24. In this case, the flange portion 6a of the locking plate 6 is exposed back and forth from the hole provided in the lower pedestal portion 31b. Thus, an opening that can be locked with the flange 6 a is provided as a locking portion 4 on the inner surface of the lower end of the lid 3.
The urging unit 35 is a compression spring, but may be a coiled tension spring, a leaf spring, or the like as long as the urging member 6 is urged in a desired direction.

  INDUSTRIAL APPLICABILITY The present invention can be used as a light-emitting device such as a guide plate or a signboard, a lid stopper for stopping a lid of a casing such as a switchboard or a cubicle, and a light-emitting device related to stopping the lid using this stopper.
