Description

Technical Field

[0001] The present invention relates to indoor lighting for a railway model arranged indoors.

Background Art

[0002] A lighting component of Patent Document 1 and a railway model having the structure shown in FIG. 9 are known as the prior art. FIG. 9(A) is a view of the railway model 900 seen from the side, and FIGS. 9(B) and 9(C) are cross-sectional views of the railway model 900 taken along the line A-A in FIG. 9(A). The railway model 900 includes a floor portion 910, wheels 920, a vehicle body 930, a light emitter 940, and a transparent substrate 950. The floor portion 910 has a conductive plate 911. The conductive plate 911 is generally made of copper. Two conductive plates 911 extend in the length direction of the floor portion 910. Electric power to the railway model 900 is supplied from a line via the wheels 920. The wheels 920 are formed of a conductive material, and although not shown, the wheels 920 and the conductive plate 911 are electrically connected. Therefore, when the railway model 900 running on a line according to a standard is placed on the line, electric power is supplied to the conductive plate 911. The difference between FIGS. 9(B) and 9(C) is the difference in the position and width of the conductive plate 911, and it often depends on the manufacturer of the railway model.

[0003] The supplied electric power is generally a DC pulse, but it may also be AC. The vehicle body 930 is arranged on the floor portion 910. The vehicle body 930 includes a door portion 931, a window portion 932, and the like. The light emitter 940 is arranged at the end on the roof side inside the vehicle body 930 and is connected to the conductive plate 911 by a conductor 942. The light emitter 940 emits light in the length direction of the vehicle body 930. The transparent substrate 950 is arranged on the roof side inside the vehicle body 930 and has prisms 951 at a plurality of locations in the length direction of the vehicle body 930. Since the light emitted by the light emitter 940 is diffused by reflection at the prisms 951 and the like, it appears as if there is an indoor light at the position of the prisms 951. The floor portion 910 may have columns 912 for supporting the transparent substrate 950. When there are no columns 912, the transparent substrate 950 is attached to the ceiling of the vehicle body 930 with double-sided tape.

[0004] In the prior art shown in FIG. 9, a light emitter 940 and a transparent substrate 950 constitute indoor lighting for a railway model. Note that the indoor lighting for a railway model is not necessarily standard equipment for a railway model and is often provided as an option.

Summary of the Invention

Problems to be Solved by the Invention

[0006] For a railway model 900 running on a track according to standards, the width of the wheels 920 is determined according to the track standards, and the width of the vehicle is approximately the same. However, in the prior art, as shown in FIGS. 9(B) and 9(C), the position and width of the conductive plate 911 differ for each manufacturer of railway models. Also, the lengths of the floor part 910 and the vehicle body 930 differ depending on the type of railway model 900 even among the same manufacturer. For example, when the railway model 900 is a bullet train, the floor part 910 and the vehicle body 930 are long, and when it is a conventional train, the floor part 910 and the vehicle body 930 are short.

[0007] Indoor lighting for a railway model is a product that may also be provided by parties other than railway model manufacturers. Railway model manufacturers basically design and manufacture indoor lighting for their own railway models. On the other hand, for those other than railway model manufacturers, there is a problem that even for a railway model running on a track according to standards, it is required to provide indoor lighting for railway models that can be used for various manufacturers and various lengths of railway models. An object of the present invention is to provide indoor lighting for railway models that can be used for various railway models.

Means for Solving the Problems

[0008] The indoor lighting for a railway model of the present invention includes a lighting unit and an adapter arranged on the roof side of the interior of the railway model. The lighting unit has a substrate, a light source, a power supply circuit, through-holes, and conducting wires. The light source is arranged in the length direction at a predetermined interval on one surface of the substrate. The power supply circuit has a rectifying section and a constant voltage supply section formed in a power supply circuit area that is part of the substrate. Two through-holes are formed in the substrate within the power supply circuit area. Two conducting wires are formed on one surface of the substrate outside the power supply circuit area so as to extend in the length direction and supply a predetermined voltage supplied by the constant voltage supply section. The adapter has screw holes for through-holes, fixing screws, and protrusions. Two screw holes for through-holes correspond to the through-holes. The fixing screws are conductive, pass through the through-holes, and fix the adapter by being inserted into the screw holes for through-holes. The protrusions are conductive and face a conductive plate arranged on the floor portion of the railway model. The light source outside the power supply circuit area is arranged between the two conducting wires. The protrusions are electrically connected to the input of the rectifying section.

Advantages of the Invention

[0009] The indoor lighting for a railway model of the present invention includes a lighting unit and an adapter arranged on the roof side of the interior of the railway model. As long as it is within the range of a railway model running on a line according to the standard, the lighting units can be made common, and the position and size of the protrusions of the adapter may be adjusted to be suitable for the conductive plate arranged on the floor portion of the railway model. Therefore, according to the indoor lighting for a railway model of the present invention, it is possible to provide indoor lighting for a railway model that can be used for various railway models.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail. Components having the same function are given the same number, and redundant explanations are omitted.

Examples

[0012] The structure of the railway model is shown in Fig. 1. Fig. 1(A) is a view of the railway model 800 seen from the side, and Figs. 1(B) and 1(C) are cross-sectional views of the railway model 800 taken along the line A-A in Fig. 1(A). The railway model 800 includes a floor portion 910, wheels 920, a car body 930, a lighting portion 100, adapters 201, 202, and compression coil springs 401, 402. The floor portion 910 has a conductive plate 911. The conductive plate 911 is generally made of copper. Two conductive plates 911 extend in the length direction of the floor portion 910. Electric power to the railway model 800 is supplied from a line (not shown) via the wheels 920. The wheels 920 are formed of a conductive material, and although not shown, the wheels 920 and the conductive plate 911 are electrically connected. Therefore, when the railway model 800 running on a line according to the standard is placed on the line, electric power is supplied to the conductive plate 911. The difference between Figs. 1(B) and 1(C) is the difference in the position and width of the conductive plate 911, which often depends on the manufacturer of the railway model.

[0013] The supplied power is generally a DC pulse, but it can also be AC. The vehicle body 930 is arranged on the floor part 910. The vehicle body 930 is provided with a door part 931, a window part 932, etc. The lighting part 100 is arranged on the roof side of the interior of the vehicle body 930. When the floor part 910 has columns 912, the lighting part 100 may be supported by the columns 912. Also, when there are no columns 912, the lighting part 100 may be attached to the ceiling of the vehicle body 930 with double-sided tape. The lighting part 100 is connected to the conductive plate 911 via the adapters 201, 202 and the compression coil springs 401, 402.

[0014] Figure 2 is a diagram showing an example of the structure of the lighting part. Figure 3 is a diagram showing a first example of the structure of the interior lighting for a railway model, and Figure 4 is an enlarged view of the vicinity of the adapter in the case of the first example of the structure. Figure 5 is a diagram showing a second example of the structure of the interior lighting for a railway model, Figure 6 is an enlarged view of the vicinity of the adapter in the case of the second example of the structure, and Figure 7 is an enlarged cross-sectional view of the vicinity of the adapter in the case of the second example of the structure. Figure 8 is a diagram showing the structure and use of the auxiliary conductive plate. The interior lighting 11, 12 for a railway model includes at least the lighting part 100 arranged on the roof side of the interior of the railway model 800 and the adapters 201, 202. The interior lighting 11, 12 for a railway model may also include the compression coil springs 401, 402. The interior lighting 11, 12 for a railway model may further include the auxiliary conductive plate 511.

[0015] Figure 2(A) is a plan view of the lighting part 100 seen from one surface 101 of the substrate 105, and Figure 2(B) is a side view of the lighting part 100 seen from the side. In Figure 2(B), one surface 101 is on the lower side and the other surface 102 is on the upper side. When the lighting part 100 is arranged on the roof side of the interior of the railway model 800, one surface 101 is on the lower side. The lighting part 100 has a substrate 105, a light source 110, a power supply circuit 120, through holes 130, and conducting wires 140.

[0016] The light source 110 is arranged in the length direction at a predetermined interval on one surface 101 of the substrate 105. Here, the "length direction" refers to the direction of the long side of the rectangular substrate 105 shown in Fig. 2(A), and is also the traveling direction of the railway model 800. The "width direction" refers to the direction of the short side of the rectangular substrate 105 shown in Fig. 2(A). There are a plurality of light sources 110, which are arranged at intervals where illumination of the railway model is desired. Therefore, it is a component whose arrangement is prioritized among the components of the lighting unit 100. An LED may be used as the light source 110, and the light source unit 115 is formed by a resistor 111 connected in series with the light source 110. By supplying a predetermined constant voltage to the light source unit 115, the light source 110 emits light. For example, the light source units 115 are arranged at intervals of 8 to 13 mm.

[0017] The power supply circuit 120 includes a rectifying unit 121 and a constant voltage supply unit 122. Also, the range including the part of the substrate 105 that forms the power supply circuit 120 will be referred to as the power supply circuit range 125. In the lighting unit 100, as described above, the position of the light source 110 is prioritized. Other components are arranged while prioritizing the light source 110. Also, when there is no pillar 912, the lighting unit 100 is attached to the ceiling of the vehicle body 930 with double-sided tape. Therefore, it is desirable that the other surface 102 of the substrate 105 has irregularities to such an extent that double-sided tape can be used.

[0018] Two through holes 130 are formed in the substrate 105 within the power supply circuit range 125. There is wiring connected to the input of the rectifying unit 121 in the vicinity of the through hole 130. For example, a conductive range may be formed around the through hole 130 on the other surface 102 and connected to the input of the rectifying unit 121 on the one surface 101 side. The rectifying unit 121 converts a DC pulse or AC supplied via the wheels 920 into DC. The constant voltage supply unit 122 is a circuit that supplies a predetermined constant voltage so that the light source 110 emits light. Both the rectifying unit 121 and the constant voltage supply unit 122 utilize existing technologies, and the configuration excluding the wiring may be arranged on one surface 101 of the substrate 105.

[0019] The two conductive wires 140 are formed on one surface 101 of the substrate outside the power circuit range 125 so as to extend in the length direction, and supply a predetermined voltage supplied by the constant voltage supply unit 122. The light source 110 outside the power circuit range 125 is disposed between the two conductive wires 140. A predetermined voltage is supplied to the light source unit 115 via the two conductive wires 140. Even within the power circuit range 125, there exists a light source unit 115 in which the light source 110 and the resistor 111 are connected in series, and a predetermined voltage supplied by the constant voltage supply unit 122 is supplied. However, the arrangement and wiring of the resistor 111 may be different from those outside the power circuit range 125.

[0020] The substrate 105 may be assumed to have a length assuming the longest railway model among various railway models. Outside the power circuit range 125, two conductive wires 140 are formed in the length direction, and the light source 110 is disposed therebetween. Therefore, if the substrate is cut between the light sources 110, the substrate 105 can be shortened while maintaining the insulation between the two conductive wires 140. Thus, the user himself / herself can adjust the length of the indoor lighting 11, 12 for the railway model according to the railway model 800 to be installed. Also, between the light sources 110 outside the power circuit range 125 and on the other surface 102 of the substrate 105, a groove 150 may be formed in the width direction of the substrate 105. Since the groove 150 is formed in the width direction on the other surface 102, the substrate 105 can be cut by folding it along the groove 150. That is, the user can easily adjust the length of the substrate 105 without using tools. For example, a glass epoxy substrate having a thickness of about 0.6 to 0.8 mm and a width of about 9.5 mm may be used for the substrate 105, and a groove 150 that can be cut by folding may be formed. Note that since the power circuit range 125 can be made sufficiently short compared to the length of the railway model 800, it is not necessary to cut the substrate 105 within the power circuit range 125.

[0021] The adapters 201 and 202 have screw holes 210 for through holes, fixing screws 301 and 302, and protrusions 300. The two screw holes 210 for through holes correspond to the through holes 130. The fixing screws 301 and 302 are conductive, pass through the through holes 130, and are inserted into the screw holes 210 for through holes to fix the adapters 201 and 202 to one surface 101 side of the substrate 105. The protrusions 300 are conductive and face the conductive plate 911 disposed on the floor portion 910 of the railway model 800. The protrusions 300 are electrically connected to the input of the rectifying unit 121 via the fixing screws 301 and 302. Since there is a wiring connected to the input of the rectifying unit 121 in the vicinity of the through holes 130, it is only necessary to connect the fixing screws 301 and 302 to the wiring.

[0022] FIG. 3(A) is a view of the indoor lighting 11 for railway models (first structural example) as seen from one surface 101 of the substrate 105, FIG. 3(B) is a side view of the indoor lighting 11 for railway models, and FIG. 3(C) is a view showing the relationship with the floor portion 910 when the indoor lighting 11 for railway models is viewed in the longitudinal direction. FIGS. 3(B) and 3(C) also show the compression coil spring 401. FIG. 4(A) is an enlarged view of the vicinity of the adapter of the indoor lighting 11 for railway models, and FIG. 4(B) is an enlarged view also showing the compression coil spring 401.

[0023] In the indoor lighting 11 for railway models, the fixing screw 301 is inserted from the other surface 102 of the substrate 105 in the direction of the adapter 201. The fixing screw 301 forms the protrusion 300 by protruding to the opposite side of the substrate 105 of the adapter 201. That is, the protrusion 300 is the tip portion of the fixing screw 301 and the screw portion near the tip portion. The compression coil spring 401 may be attached to the screw portion near the tip portion of the fixing screw 301. With such an attachment, even a user can easily attach it. Therefore, when transferring to a user or the like, the compression coil spring 401 may be transferred or the like in a state where it is not attached. Entanglement of the compression coil springs 401 with each other can also be prevented.

[0024] In the indoor lighting 11 for a railway model, the through hole 130 will face the conductive plate 911 disposed on the floor portion 910 of the railway model 800. When the conductive plate 911 is disposed at a position close to the center of the floor portion 910 as shown in FIG. 3(C), it is easy to adopt the configuration of the indoor lighting 11 for a railway model. Since it is electrically connected to the input of the rectifying unit 121 via the fixing screw 301, it is desirable to dispose the through hole 130 at the end of the power supply circuit range 125.

[0025] FIG. 5(A) is a view of the indoor lighting 12 (second structural example) for a railway model seen from one surface 101 of the substrate 105, FIG. 5(B) is a side view of the indoor lighting 12 for a railway model, and FIG. 5(C) is a view showing the relationship with the floor portion 910 when the indoor lighting 12 for a railway model is seen in the length direction. FIGS. 5(B) and (C) also show the compression coil spring 402. FIG. 6(A) is an enlarged view of the vicinity of the adapter of the indoor lighting 12 for a railway model, and FIG. 6(B) is an enlarged view also showing the compression coil spring 401. In the indoor lighting 12 for a railway model, the adapter 202 also has two conductive portions 250. The conductive portion 250 electrically connects the fixing screw 302 inserted into the through hole screw hole 210 and the protrusion 300.

[0026] More specifically, for example, the adapter 202 for the indoor lighting 12 of the railway model also has two position adjustment screw holes 220, two conductive parts 250, and two adjustment screws 303. And one set is formed by one through-hole screw hole 210, one position adjustment screw hole 220, and one conductive part 250 respectively. That is, two sets of the combination of the through-hole screw hole 210, the position adjustment screw hole 220, and the conductive part 250 are formed. The conductive part 250 electrically connects the fixing screw 302 inserted into the through-hole screw hole 210 of the same set and the adjustment screw 303 inserted into the position adjustment screw hole 220. The adjustment screw 303 inserted from the substrate 105 side into the position adjustment screw hole 220 protrudes from the opposite side of the substrate 105 of the adapter 202 to form a protrusion 300. That is, the protrusion 300 is the tip of the adjustment screw 303 and the screw part close to the tip. The compression coil spring 402 may be attached to the screw part close to the tip of the adjustment screw 303. With such an attachment, even a user can easily attach it. Therefore, when transferring etc. to a user, the compression coil spring 402 may be transferred etc. in a state where it is not attached. It is also possible to prevent the compression coil springs 402 from getting entangled with each other.

[0027] The position adjustment screw hole 220 is preferably formed so as to have a gap with the substrate 105 or formed at a position without the substrate 105 when the adapter 202 is fixed to the substrate 105. This is to prevent the head of the adjustment screw 303 from deforming the substrate 105. When the conductive plate 911 is arranged at the end of the floor part 910 as shown in FIG. 5(C), the configuration of the indoor lighting 12 for the railway model is suitable.

[0028] In the example of the adapter 202 shown in FIG. 7, the conductive part 250 is provided with a hole through which the adjustment screw 303 passes. When the adjustment screw 303 is attached, the conductive part 250 comes into contact with the head of the adjustment screw 303. The conductive part 250 is not provided with a hole at the position of the fixing screw 302. When the adapter 202 is fixed to the substrate 105 with the fixing screw 302, the tip of the fixing screw 302 comes into contact with the conductive part 250. Note that the head height of the adjustment screw 303 may be below the gap between the substrate 105 and the adapter 202.

[0029] The indoor lighting 11, 12 for a railway model may also include an auxiliary conductive plate 511 as shown in FIG. 8. In some cases, it may be difficult to bring the compression coil springs 401, 402 into contact with the conductive plate 911 itself. In such a case, a part of the conductive plate 911 may be replaced with the auxiliary conductive plate 511. The auxiliary conductive plate 511 is arranged so as to partially overlap with the power supply conductive plate 911 arranged on the floor portion 910 of the railway model 800. Therefore, the auxiliary conductive plate 511 and the conductive plate 911 are electrically connected. Further, the auxiliary conductive plate 511 comes into contact with the compression coil springs 401, 402. The auxiliary conductive plate 511 may be provided with a stopper 512 to stabilize its position with respect to the floor portion 910. The stopper 512 has the effect of preventing the auxiliary conductive plate 511 from entering the inside of the floor portion 910.

[0030] The indoor lighting 11, 12 for a railway model according to the present invention includes a lighting unit 100 and adapters 201, 202 arranged on the roof side of the interior of the railway model 800. As long as it is within the range of a railway model running on a line according to a standard, the lighting unit 100 can be made common, and the position and size of the protrusions 300 of the adapters 201, 202 may be adjusted to be suitable for the conductive plate 911 arranged on the floor portion 910 of the railway model. Therefore, the manufacturing cost of the lighting unit 100, which is high, can be reduced by mass production effects, and the differences for each railway model can be adjusted by the adapters 201, 202. Therefore, according to the indoor lighting 11, 12 for a railway model of the present invention, it is possible to provide indoor lighting for a railway model that can be used for various railway models.
