Embodiment for Carrying Out the Invention

[0012] [Embodiment] Hereinafter, a method for manufacturing an internally illuminated sign according to an embodiment of the present invention, a fixture used in the manufacturing method, and an internally illuminated sign manufactured by the manufacturing method will be described.

[0013] FIG. 1 is a diagram showing a portable generator 2 and an existing internally illuminated sign 1A that receives power supply from the portable generator 2., The internally illuminated sign 1A is typically a movable sign used at night at a road construction site or the like.,

[0014] The internally illuminated sign 1A includes a base member 11, a pillar 12 erected from the base member 11, a first sign 13A and a second sign 14A attached to the upper part of the pillar 12, and a warning light 15A attached to the uppermost part of the pillar 12.

[0015] FIG. 2 is a diagram showing the inside of the first sign 13A.

[0016] The first sign 13A comprises a housing body 131 and a housing cover 132 that covers the opening of the housing body 131. Inside the housing body 131, a mounting bracket 133 is fixed for the user to install a fluorescent lamp 3, which is the light source. The fluorescent lamp 3 is lit by power supplied from a portable generator 2 (see Figure 1).

[0017] Note that in Figure 2, the wires and sockets for supplying power to the fluorescent lamp 3 are omitted from the illustration.

[0018] Multiple screw holes O3 (for example, 4 vertically x 2 rows, totaling 8) are provided on the inner wall of the housing body 131.

[0019] Figure 3 shows the structure for fixing the first marker 13A to the support post 12. The first marker 13A is attached to the support post 12 using a connecting fitting 16, a bolt 17, and a nut 18. The connecting fitting 16 shown as an example in Figure 3 is a fitting called a saddle band.

[0020] The bolt 17 passes through the screw hole O3 provided in the housing body 131 (see Figure 2) of the first sign 13A, and the screw hole provided in the connecting fitting 16. Then, a nut 18 is screwed onto the bolt 17 on the back of the housing body 131, thereby fixing the first sign 13A to the support column 12 together with the connecting fitting 16.

[0021] Figure 4 shows the inside of the second marker 14A.

[0022] The second sign 14A comprises a housing body 141 and a housing cover 142 that covers the opening of the housing body 141. Inside the housing body 141, a mounting bracket 143 is fixed for the user to install a fluorescent lamp 4, which is the light source. The fluorescent lamp 4 is lit by power supplied from a portable generator 2 (see Figure 1).

[0023] Note that in Figure 4, the wires and sockets for supplying power to the fluorescent lamp 4 are omitted from the illustration.

[0024] Screw holes O4 are provided on the inner wall of the housing body 141.

[0025] The user modifies an existing internally illuminated sign 1A into a battery-powered internally illuminated sign by following the procedure described below, in accordance with the manufacturing method of an internally illuminated sign according to one embodiment of the present invention.

[0026] First, the user removes the fluorescent lamp 3 (see Figure 2) from the housing body 131 of the first sign 13A (step S1). Figure 5 shows the inside of the first sign 13A with the fluorescent lamp 3 removed.

[0027] Next, the user prepares the reflective members 134(1) and 134(2) (step S2). Figure 6 is a plan view of the reflective members 134(1) and 134(2).

[0028] The reflective member 134(1) is made by cutting a flexible reflective sheet into a circular shape, with portions corresponding to the mounting bracket 133 (see Figure 5) and screw hole O3 (see Figure 5) cut out.

[0029] The reflective member 134(2) is made by cutting a flexible reflective sheet, and its vertical length is approximately the same as the depth of the inner surface of the housing body 131 (see Figure 5), and its horizontal length is approximately the same as the circumference of the circle whose diameter is the inner diameter of the housing body 131.

[0030] The flexible reflective sheets used in these reflective members are preferably diffuse reflective sheets with high reflectivity and high diffuse reflectivity. For example, white PET film, foamed PET sheet, fluororesin (PTFE) sheet, etc., can be used.

[0031] Next, the user attaches the reflective members 134(1) and 134(2) to the inside of the housing body 131 (step S3).

[0032] Figure 7 shows the state in which the reflective members 134(1) and 134(2) are attached to the inside of the housing body 131. The reflective member 134(1) is attached to the bottom surface (the back surface visible from the front) of the housing body 131, and the reflective member 134(2) is attached to the circumferential inner surface of the housing body 131.

[0033] It is desirable to use a highly removable adhesive (including an adhesive sheet) for attaching the reflective members 134(1) and 134(2). This makes it easy to restore the sign to its original condition upon return, for example, if the internally illuminated sign 1A is a leased item.

[0034] Next, the user prepares the mounting bracket 135 (step S4).

[0035] Figure 8 is a front view of a mounting fixture 135 according to one embodiment of the present invention.

[0036] The mounting fixture 135 comprises a pair of tension poles 1351 (1351R, 1351L), a plurality of cushioning members 1352 (1352RU, 1352RB, 1352LU, 1352LB), a pair of connecting bars 1353 (1353U, 1353B), and a plurality of magnetic mounts 1354 (1354RU, 1354RB, 1354LU, 1354LB).

[0037] The tensioning pole 1351 is a rod-shaped device positioned between opposing inner walls of the housing body 131 (see Figure 3) and has a biasing mechanism that generates a force from the inside outwards relative to the inner walls.

[0038] Each tension pole 1351 has an outer cylindrical member 13511, an inner cylindrical member 13512 that is slidably inserted into the outer cylindrical member 13511, and leg members 13513 and 13514 provided at both ends.

[0039] A spring (not shown) is inserted inside the outer cylindrical member 13511, and the biasing force of this spring biases the inner cylindrical member 13512 in a direction that pushes it outward (upward in Figure 8).

[0040] The cushioning member 1352 is positioned between the foot members 13513 and 13514 and the inner surface of the housing body 131.

[0041] The cushioning member 1352 deforms to fill the gap between the leg members 13513 and 13514 and the inner surface of the housing body 131, and also plays a role in weakening vibrations that travel from the housing body 131 toward the tension pole 1351.

[0042] The connecting bar 1353 is a component that connects and fixes a pair of tension poles 1351R and 1351L to each other.

[0043] The magnetic mount 1354 includes a hose clamp 13541 and a magnetic plate 13542.

[0044] The hose clamp 13541 is attached to the outer cylindrical member 13511 or the inner cylindrical member 13512 of the tensioning pole 1351.

[0045] The hose clamp 13541 has, for example, a cylindrical band portion that partially overlaps in the circumferential direction, and a pair of clip portions attached to two locations on the cylindrical portion so as to extend radially outward.

[0046] When a user firmly pinches the clip portion of the hose clamp 13541 with their fingers, the clamp portion expands and separates from the outer surface of the outer cylindrical member 13511 or the inner cylindrical member 13512.

[0047] In that state, the user moves the hose clamp 13541 to a desired position in the extension direction of the outer cylindrical member 13511 or the inner cylindrical member 13512, and to a desired angular position around the axis of the outer cylindrical member 13511 or the inner cylindrical member 13512, and then releases their fingers from the clip portion.

[0048] When the user's finger moves away from the clip portion of the hose clamp 13541, the band member, which had been expanded by the force of the user's finger, attempts to return to its original shape, and the band portion contacts the outer surface of the outer cylindrical member 13511 or the inner cylindrical member 13512 with an inward bias. As a result, the frictional force between the inner surface of the band portion of the hose clamp 13541 and the outer surface of the outer cylindrical member 13511 or the inner cylindrical member 13512 fixes the hose clamp 13541 in the desired position on the outer cylindrical member 13511 or the inner cylindrical member 13512.

[0049] The magnetic plate 13542 is fixed to the tension pole 1351 by a hose clamp 13541. The magnetic plate 13542 is a plate-shaped member made of iron.

[0050] If a gap is created between the hose clamp 13541 and the inner cylindrical member 13512 or the outer cylindrical member 13511, a spacer (not shown) may be used to fill the gap.

[0051] The tensioning pole 1351, the buffer member 1352, and the connecting bar 1353 constitute an example of a fixing mechanism, which is a mechanism for the mounting fixture 135 to fix itself to the housing of the sign.

[0052] Furthermore, the magnetic mount 1354 constitutes an example of a coupling mechanism, which is a mechanism for the mounting fixture 135 to detachably connect to a light-emitting device (light-emitting device 136, described later).

[0053] Next, the user installs the prepared mounting bracket 135 inside the housing body 131 (step S5).

[0054] Figure 9 shows the mounting bracket 135 installed inside the housing body 131.

[0055] The user inserts each tensioning pole 1351 (see Figure 8) of the mounting fixture 135 into the housing body 131 while it is retracted against its biasing force.

[0056] Then, the leg members 13513 and 13514 (see Figure 8) of each tension pole 1351 are positioned to contact the opposing inner walls of the housing body 131 (the surfaces to which the reflective members 134(2) in Figure 7 are attached) via the cushioning member 1352 (see Figure 8), thereby releasing the force that had been constricting each tension pole 1351.

[0057] As a result, the tension pole 1351 exerts a force on the inner wall of the housing body 131 from the inside out due to the biasing force of the spring (not shown), and the mounting bracket 135 is fixed inside the housing body 131.

[0058] Next, the user prepares two light-emitting devices 136 (step S6).

[0059] Figure 10 is an external view of the light-emitting device 136, where Figure 10(A) is a front view and Figure 10(B) is a right side view.

[0060] The light-emitting device 136 comprises a light-emitting section 1361, a base unit 1362, and two magnets 1363.

[0061] The light-emitting section 1361 includes an LED (not shown) and a cover that covers the LED.

[0062] The base unit 1362 incorporates a battery (not shown), an LED drive circuit (not shown), and a battery charging circuit (not shown).

[0063] The two magnets 1363 are mounted on the bottom surface of the base unit 1362 with a gap between them.

[0064] Next, the user connects the two prepared light-emitting devices 136 (136L, 136R) to the mounting bracket 135 (step S7).

[0065] Figure 11 shows the state in which two light-emitting devices 136 (136L, 136R) are connected to the mounting fixture 135.

[0066] The user brings the magnet 1363 (see Figure 10) of each light-emitting device 136 close to the magnetic plate 13542 (see Figure 8) of the magnetic mount 1354 (see Figure 8) of the mounting fixture 135.

[0067] As a result, the magnet 1363 of the light-emitting device 136 and the magnetic plate 13542 of the magnetic mount 1354 are attracted to each other by magnetic force, and the two light-emitting devices 136 (136L, 136R) are detachably connected to the mounting fixture 135.

[0068] Next, the user adjusts the direction of light emission from the light-emitting device 136 (step S8). This adjustment is made to minimize unevenness in the brightness of the light transmitted through the sign (housing cover 132) and to make the sign easier to see.

[0069] The user can adjust the direction of light emission from the light-emitting device 136 by firmly pinching the clip portion of the hose clamp 13541 (see Figure 8) with their fingers to widen the clamp portion, changing the angle position of the hose clamp 13541 relative to the tension pole 1351 (see Figure 8), and then releasing their fingers from the clip portion.

[0070] Figure 12 is a diagram illustrating how the light emission direction of the light-emitting device 136 has been adjusted.

[0071] Figure 12(A) shows a state in which the primary light emission direction (indicated by the arrow) of the light emission device 136L is adjusted to the left, and the primary light emission direction (indicated by the arrow) of the light emission device 136R is adjusted to the right.

[0072] Figure 12(B) shows the state in which the light-emitting device 136L has been rotated approximately 30 degrees clockwise when viewed from above, and the light-emitting device 136R has been rotated approximately 30 degrees counterclockwise when viewed from above, compared to the state in Figure 12(A).

[0073] In this way, by directing the light emission direction of the light-emitting device 136 towards the inner surface or bottom surface of the housing body 131 to which the reflective member 134 (see Figure 7) is attached, rather than towards the housing cover 132 (see Figure 5), the light from the light-emitting unit 1361 is diffusely reflected by the reflective member 134, making it possible to illuminate the housing cover 132 more uniformly.

[0074] After adjusting the direction of light emission, the user attaches the housing cover 132 (see Figure 5) to the housing body 131 and closes it.

[0075] This completes the modification work on marker 13A. Hereafter, the modified marker 1 will be referred to as marker 13B.

[0076] The user then performs the same procedure as steps S1 to S8 above for the second sign 14A (see Figure 4), removing the fluorescent lamp 4 (see Figure 4), attaching the reflective members 134(1) and 134(2), installing the mounting bracket 135, installing and adjusting the direction of the light-emitting devices 136L and 136R, and closing the housing cover 142 (see Figure 4). Hereinafter, the modified second sign will be referred to as the second sign 14B.

[0077] Next, the user removes the warning light 15A (see Figure 1) from the support column 12 (step S10). This removal is done, for example, by removing the bolts and nuts (not shown in Figure 1, etc.) that secure the warning light 15A to the support column 12.

[0078] Next, the user attaches a warning light 15B, which has a separate, removable battery built in and emits light using power supplied from that battery, to the very top of the support pole 12.

[0079] With the above steps completed, the modification of the existing internally illuminated sign 1A is finished. Hereafter, the modified internally illuminated sign will be referred to as internally illuminated sign 1B.

[0080] Figure 13 shows the external appearance of the internally illuminated sign 1B.

[0081] The first sign 13B, the second sign 14B, and the warning light 15B of the internally illuminated sign 1B are powered by electricity supplied from a built-in battery.

[0082] Internally illuminated sign 1B has the same appearance as the original internally illuminated sign 1A (see Figure 1), but differs in that it emits light without requiring power supply from an external power source such as the portable generator 2 (see Figure 1).

[0083] The user removes the light-emitting devices 136L and 136R from the first marker 13B and the second marker 14B, for example, after completing work at the construction site for the day.

[0084] Since the light-emitting devices 136L and 136R are detachably connected to the mounting fixture 135 by magnetic force, the user can easily remove them without using tools.

[0085] Additionally, the user removes the battery (not shown) from the warning light 15B.

[0086] Subsequently, the user charges the batteries of the removed light-emitting devices 136L and 136R, as well as the battery removed from the warning light 15B, at their office or other location.

[0087] Then, for example, at the start of work at the construction site the following day, the user attaches the charged light-emitting devices 136L and 136R to the first sign 13B and the second sign 14B, and attaches the charged battery to the warning light 15B.

[0088] By following the steps S1 to S10 described above (a method for manufacturing an internally illuminated sign according to one embodiment of the present invention), the user can easily change an existing internally illuminated sign 1A that requires an external power source such as a portable generator 2 to a battery-powered internally illuminated sign 1B.

[0089] Furthermore, since the mounting bracket 135 is fixed by the biasing force of the tension pole 1351, and the reflective members 134(1) and 134(2) are attached with a removable adhesive, the user can easily return the internally illuminated sign 1B to the state of the internally illuminated sign 1A before modification by removing the mounting bracket 135, peeling off the reflective members 134(1) and 134(2), and reinstalling the fluorescent lamp 3.

[0090] [Differentiation] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible. Examples of such modifications are shown below. Two or more of the following modifications may be combined as appropriate.

[0091] (Variation 1) The configuration of the mounting fixture 135 described in the above embodiment is not limited to that shown in Figure 8, and can be modified in various ways.

[0092] For example, the leg members 13513 and 13514 of the tension pole 1351 may be made of rollers.

[0093] Figure 14 shows the state in which the light-emitting devices 136L and 136R are installed inside the housing body 131 using a mounting fixture 135 in which the foot members 13513 and 13514 are made of rollers.

[0094] In this configuration, the mounting bracket 135 (foot members 13513 and 13514) and the inner wall of the housing body 131 (reflective member 134(2)) will be in contact at a single point.

[0095] Furthermore, the lengths of the connecting bars 1353U and 1353B may be adjustable. This allows the mounting fixture 135 to be more widely applicable to various housing bodies 131 having different inner diameters.

[0096] Furthermore, the number of tension poles 1351 provided by the mounting fixture 135 is not limited to the two shown in the above embodiment. For example, there may be one.

[0097] Figure 15 shows a configuration in which, using a mounting bracket 135 with one tension pole 1351, light-emitting devices 136U and 136B, which have a similar configuration (built-in battery), are installed inside the housing body 131 instead of light-emitting devices 136L and 136R.

[0098] The mounting fixture 135 in this modified example comprises a tensioning pole 1351, a T-shaped member 1355, and a connecting fitting 1356 (for example, a saddle band).

[0099] The T-shaped member 1355 is made of a magnetic material (for example, iron) and is fixed to the tension pole 1351 by a connecting fitting 1356.

[0100] The two light-emitting devices 136U and 136B are attached to the T-shaped member 1355 by magnetic force, back to back, such that their respective main light-emitting directions are opposite to each other (180 degrees apart).

[0101] As a result, the light-emitting device 136U and the light-emitting device 136B are integrated, forming a light-emitting unit that is close to a cylindrical shape overall, enabling light emission in approximately 360 degrees around its longitudinal axis.

[0102] With this configuration, since there is only one tension pole 1351, the degree to which the light from the light-emitting device 136 is blocked by the tension pole 1351 can be reduced.

[0103] (Modification 2) The fixing mechanism of the mounting fixture 135 is not limited to the one using the tension pole 1351 described in the above embodiment.

[0104] For example, a screw-based fixing mechanism may be adopted, utilizing the existing screw holes O3 (see Figure 2) in the housing body 131.

[0105] Figure 16 shows the state in which the light-emitting devices 136U and 136B are attached by magnetic force to a mounting bracket 135, which is attached to the housing body 131 by a screw fixing mechanism using existing screw holes O3 (which are hidden and not visible in Figure 16). Figure 16(A) is a front view, and Figure 16(B) is a top view of the mounting bracket 135 (the housing body 131 is a cross-sectional view taken horizontally and viewed from above).

[0106] The mounting fixture 135 according to this modified example has a T-shaped member 1355. The T-shaped member 1355 is the same as the T-shaped member 1355 according to Modified Example 1 (see Figure 15), and is made of a magnetic material (for example, iron).

[0107] The T-shaped member 1355 is fixed to the inside of the housing body 131 by screwing a bolt 17 and a nut 18 into it. Specifically, the bolt 17 passes through the screw hole (not shown) of the T-shaped member 1355, the screw hole O3 of the housing body 131, and the screw hole provided in the connecting fitting 16, and is screwed into the nut 18 on the back of the housing body 131. In other words, in this modified example, the mounting fixture 135 is fixed to the inside of the housing body 131 by fastening it together with the housing body 131 using the bolt 17 and nut 18 used to fix the housing body 131 to the support column 12.

[0108] The two light-emitting devices 136U and 136B are attached to the T-shaped member 1355 by magnetic force in a back-to-back position, similar to the modification 1 (see Figure 15), such that their respective main light-emitting directions are opposite to each other (180 degrees apart).

[0109] In the example shown in Figure 16, a cushioning member 1352 is placed between the T-shaped member 1355 and the bottom surface of the housing body 131. This cushioning member 1352 plays a role in reducing vibrations transmitted from the housing body 131 to the T-shaped member 1355, and consequently to the light-emitting devices 136U and 136B. As a result, even if the batteries built into the light-emitting devices 136U and 136B are lithium-ion batteries, which are prone to ignition due to impact, the risk of such ignition is reduced.

[0110] Furthermore, the fixing mechanism for the mounting bracket 135 may utilize the fluorescent lamp holder 137 provided on the housing body 131.

[0111] Figure 17 shows how the light-emitting devices 136U and 136B are installed inside the housing body 131 using a mounting fixture 135 equipped with a fixing mechanism that utilizes a holder 137 for fluorescent lamps.

[0112] Figure 17(A) shows the inside of the housing body 131 with the fluorescent lamp removed. The housing body 131 is provided with a holder 137 for holding the fluorescent lamp.

[0113] Figure 17(B) is a front view of the mounting fixture 135 according to this modified example. The mounting fixture 135 comprises a dummy fluorescent lamp 1357, a pair of mounting brackets 1358 (1358U, 1358B), and magnetic plates 13542 attached to each mounting bracket 1358.

[0114] The dummy fluorescent lamp 1357 is a component whose shape mimics that of a fluorescent lamp, and it constitutes the fixing mechanism of the mounting fixture 135. However, the shape of the dummy fluorescent lamp 1357 does not need to be entirely mimicking that of a fluorescent lamp; the part other than the part held by the holder 137 may differ in shape from that of a fluorescent lamp.

[0115] The magnetic plate 13542 attached to the mounting bracket 1358 constitutes the connecting mechanism of the mounting fixture 135.

[0116] The user inserts the dummy fluorescent lamp 1357 of the mounting bracket 135 shown in Figure 17(B) into the fluorescent lamp holder 137 of the housing body 131 in the state shown in Figure 17(A). As a result, the mounting bracket 135 is fixed to the housing body 131, as shown in Figure 17(C).

[0117] Subsequently, the user brings the magnet 1363 (see Figure 10) of the light-emitting device 136U or 136B close to the magnetic plate 13542 attached to the mounting bracket 1358U or 1358B, respectively.

[0118] As a result, the light-emitting devices 136U and 136B are connected to the mounting fixture 135 by magnetic force, resulting in the state shown in Figure 17(D).

[0119] (Variation 3) The connecting mechanism between the mounting bracket 135 and the light-emitting device 136 is not limited to the magnetic connecting mechanism described in the above embodiment (where a magnetic material is provided on the mounting bracket 135 and a magnet is provided on the light-emitting device 136), as long as it can be easily attached and detached by the user.

[0120] For example, a magnet may be provided on the mounting bracket 135, and a magnetic material such as iron may be provided on the light-emitting device 136.

[0121] Furthermore, the mounting bracket 135 and the light-emitting device 136 may each be provided with magnets arranged so that the polarity of their opposing surfaces is different.

[0122] Alternatively, a mechanical fitting mechanism may be used as a connecting mechanism instead of, or in addition to, magnetic force.

[0123] In that case, the mounting fixture 135 has a fitting portion that fits with the fitting portion of the light-emitting device 136.

[0124] Examples of mechanical fitting mechanisms for connecting parts include the following:

[0125] Bayonet-type mechanism: Similar to changing a camera lens, this mechanism involves aligning the projection on the flash unit 136 with the groove on the mounting bracket 135 and inserting it, then rotating it slightly to lock it in place.

[0126] Sliding mechanism: A mechanism in which a groove (rail) is provided on the mounting bracket 135, and a corresponding projection on the light-emitting device 136 is slid into place. A spring-type locking pin or a simple stopper may be provided at the end to prevent detachment due to vibration.

[0127] Snap-fit ​​mechanism (clip type): A mechanism that secures the light-emitting device 136 by pressing it into a claw (clip) made of resin or metal, which is provided on the mounting bracket 135 side.

[0128] Alternatively, a fastening mechanism using hook-and-loop fasteners may be used instead of, or in addition to, magnetism.

[0129] In that case, when the pair of mutually engaging members constituting the hook-and-loop fastener are designated as a first member and a second member, the mounting fixture 135 has the first member and the light-emitting device 136 has the second member. Alternatively, the mounting fixture 135 may have the second member and the light-emitting device 136 may have the first member.

[0130] (Modification 4) In the above embodiment, the magnetic mount 1354 having the hose band 13541 is an example of a connecting mechanism that connects to the fixing mechanism (tension pole 1351) of the mounting fixture 135 in a way that allows the position (specifically, the direction of light emission) of the light-emitting part 1361 (LED, etc.) of the light-emitting device 136 to be changed.

[0131] The configuration of the coupling mechanism that allows the position of the light-emitting part 1361 to be changed is not limited to one using a hose clamp 13541, and other configurations may be adopted.

[0132] For example, the configuration may allow the angle of the part to which the light-emitting device 136 is mounted to be changed by loosening and tightening screws.

[0133] (Variation 5) The cushioning member 1352 described in the above embodiment and modified example 2 (see Figure 16) is an example of a cushioning material that reduces vibrations transmitted from the housing body 131 to the battery (not shown) of the light-emitting device 136.

[0134] The cushioning material is not limited to the cushioning member 1352 (e.g., rubber material), but other types of cushioning materials (e.g., metal springs, air springs, etc.) may be used as long as they can mitigate vibrations transmitted from the housing to the battery of the light-emitting device 136.

[0135] Furthermore, the position where the cushioning material is placed is not limited to the above embodiment (between the tensioning pole 1351 and the housing body 131) or the modified example 2 (between the T-shaped member 1355 and the housing body 131). For example, the cushioning material may be placed between the connecting mechanism of the mounting fixture 135 and the light-emitting device 136, or the cushioning material may be placed inside the light-emitting device 136 between the battery and the surrounding components.

[0136] (Experimental variation 6) A retractable caster 19 may be attached to the base member 11 of the internally illuminated sign 1A (see Figure 1) or the internally illuminated sign 1B (see Figure 13).

[0137] Figure 18 shows an internally illuminated sign 1B equipped with a base member 11 to which retractable casters 19 that can be raised, lowered, and locked by pedal operation are attached. Three or more retractable casters 19 are attached to the base member 11.

[0138] The retractable caster 19 has a mechanism that allows the caster (wheel) portion to be raised and lowered by pedal operation.

[0139] When the user lifts the pedal of the retractable caster 19, the caster rises, and the bottom surface of the base member 11 makes contact with the ground. As a result, the internally illuminated sign 1B is stably installed and cannot be moved. Consequently, even if the battery of the light-emitting device 136 is a lithium-ion battery that is prone to ignition due to impact, the risk of ignition due to impact while the internally illuminated sign 1B is being moved is reduced.

[0140] Conversely, when the user presses down on the pedal, the casters are pressed against the ground, and the entire base member 11 is lifted off the ground. As a result, the internally illuminated sign 1B is supported by the casters and becomes easily movable.

[0141] Furthermore, the retractable caster 19 has a cantilever structure. This cantilever structure also has the effect of absorbing vibrations transmitted from the road surface when moving the internally illuminated sign 1B.

[0142] (Example 7) In the above embodiment, the light-emitting device 136 has a built-in battery, but it is not limited to this. For example, the light-emitting device 136 may be configured to receive power from an external battery connected by an electric wire.

[0143] Furthermore, the battery built into the light-emitting device 136 may be removable. In that case, the user can remove the battery from the light-emitting device 136, take only the battery back to the office or elsewhere, and charge it.

[0144] (Variation 8) In the above embodiments, the internally illuminated sign 1A (see Figure 1) and the internally illuminated sign 1B (see Figure 13) are described as portable signs, but the present invention is not limited thereto. The mounting fixture, manufacturing method, and internally illuminated sign according to the present invention are also applicable to fixed-installation signs.

[0145] (Extreme variation 9) The shapes, numbers, sizes, etc., of each component described with reference to the figures in the above embodiments and variations 1 to 8 are merely illustrative examples and may be modified as appropriate without departing from the spirit of the present invention.

[0146] For example, the shapes of the reflective members 134(1) and 134(2) are not limited to the shapes exemplified in Figure 6 (a circle with a portion cut out, a rectangle with an unfolded circumference). A configuration in which numerous rectangular or other shaped reflective members are arranged (attached) in a row on the inner surface and bottom surface of the housing body 131 or housing body 141 is also possible.
