Description

  The present invention relates to a lighting device and a home fall warning device, and more particularly, to a lighting device whose light emission angle does not change even when a stone or the like collides, and a home fall warning device using the same.

  There is a gap between the station platform and the railway vehicle, but to prevent passengers from accidentally falling into the gap when passengers get on and off the platform, the platform is located in the station premises with the railway vehicle close to the platform. It is shaped to enter and stop. However, for example, when a platform is provided at a position where the track is curved, a relatively wide gap is inevitably formed between the platform and the railway vehicle.

  In recent years, as shown in FIG. 12, for example, as shown in FIG. 12, the lower part of the platform H is illuminated to make the passenger aware that there is such a gap between the platform and the railway vehicle. There is also a station that is provided with the apparatus 100 so as to illuminate a portion near the platform H on the side wall of the railway vehicle C, in particular, near the lower portion of the door of the railway vehicle C from below. In some cases, a rotating lamp used for an emergency vehicle or the like is used as the lighting device 100.

  However, when a lighting device having a flat radiating surface as illustrated in FIG. 12 is used as the illuminating device 100 that illuminates the railway vehicle C in this way, stones and the like that are jumped off by the wheels of the railway vehicle C are used as the radiating surface. If it hits, a radiation surface will be broken or an internal light source will be damaged. In addition, since a moment is applied by the collision of a stone or the like, the radiation surface of the lighting device 100 rotates around the support shaft 101 supported by the support arm portion 102 to change the radiation angle. Or the door part may not be properly illuminated. And if the part of the gap G is not properly illuminated, the passenger P cannot be notified of the existence of the gap G.

  However, on the other hand, there are many cases where the place where the lighting device 100 can be disposed is limited due to the structural limitation of the platform H. In this case, the lighting device should be appropriately adjusted in the direction of light emission so that the lighting device can be installed in a limited installation location and the side wall and door portion of the railway vehicle C can be appropriately illuminated. Is required to be possible.

  In this way, the illumination device that illuminates the gap G between the platform H and the railway vehicle C does not easily change the radiation angle even when it is hit by a bounced stone or the like, but on the other hand, for example, when the illumination device is installed As described above, when the worker intends to adjust the radiation angle, it is required that the radiation angle can be appropriately adjusted.

  Therefore, an object of the present invention is to provide an illuminating device in which the direction of light emission can be reliably maintained even when an impact is applied, and the direction of light emission can be appropriately adjusted. Another object of the present invention is to provide a home fall warning device capable of effectively calling attention so that passengers do not fall from the gap between the platform and the railway vehicle.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a lighting device and a home fall warning device according to the present invention will be described with reference to the drawings.

[Lighting device]
First, an embodiment of a lighting device according to the present invention will be described. As shown in FIG. 1, the illumination device 1 according to the present embodiment includes a pipe 2, a cap 3, a connector 4, a pipe clamp 5, a substrate 6, a light source 7, and the like.

  The pipe 2 is formed in a hollow cylindrical shape and is formed of a transparent material. As a material constituting the pipe 2, a polycarbonate pipe excellent in impact resistance, weather resistance, water resistance, transparency, dimensional stability and the like is preferably used. For the diameter of the pipe 2 and the length in the axial direction, the thickness of the peripheral wall 2a and the like, appropriate ones are selected according to the usage status of the lighting device 1 and the like.

In the present embodiment, the photocatalyst is applied to the outer surface of the peripheral wall 2a of the pipe 2, for example, by coating with liquefied glass containing titanium oxide (TiO ₂ ), which is a photocatalytic active material. By applying the photocatalyst to the peripheral wall 2 of the pipe 2 in this way, it becomes possible to float contaminants such as mud adhering to the peripheral wall 2 so as to flow down from the peripheral wall 2a with rainwater or the like. It becomes possible to have a function.

  Caps 3 are provided at the opening portions at both ends of the pipe 2, respectively, and the cap 3 closes the opening of the pipe 2 in a watertight state. For example, when the end of one side of the pipe 2 is formed so as to be closed in advance, the open end of the other side is closed in a watertight state by the cap 3.

  In this embodiment, as shown in FIG. 2, the cap 3 has a cylindrical insertion portion 3a to be inserted into the pipe 2, and an abutment with the end of the peripheral wall 2a of the pipe 2 having a larger diameter than the insertion portion 3a. It is comprised with the disk-shaped collar part 3b. A plurality of ribs 3c having a diameter slightly larger than the inner diameter of the peripheral wall 2a of the pipe 2 are formed on the outer peripheral surface of the insertion portion 3a of the cap 3 in an annular shape.

  The cap 3 is deformed so that each rib 3c is fitted to the inner peripheral surface of the peripheral wall 2a of the pipe 2 when the insertion portion 3a is inserted into the opening portion of the pipe 2, and each rib 3c and the peripheral wall 2a of the pipe 2 are inserted. The pipe is pressed in such a way that pressure is generated between the pipe 2 and the flange 3b until it is pushed into contact with the end of the peripheral wall 2a of the pipe 2 so that water tightness with the pipe 2 is ensured. The two openings are closed. In FIG. 2, illustration of a pipe clamp 5 and a substrate 6 described later is omitted.

  In the present embodiment, the cap 3 is provided with a connector 4 for connecting a wiring cable 8 connected to a light source 7 described later provided inside the pipe 2 and an external wiring cable 9. The connector 4 may be provided at the center of the disc-shaped collar portion 3b of the cap 3 as shown in FIG. 2, or may be provided at an eccentric position as shown in FIG. When the connector 4 is attached to the cap 3, a measure is taken to prevent rainwater or the like from entering the pipe 2 through the attachment portion.

  As shown in FIG. 1, both end portions of the pipe 2 are each gripped by a pipe clamp 5 installed on the ground or a predetermined mounting location. Specifically, assuming that the direction indicated by the arrow X in the figure is the front-rear direction of the lighting device 1, the pipe clamp 5 is a pair of sandwiching pieces extending upward from both front and rear ends of the base portion 5a provided below. The pipe 2 is inserted into a substantially circular space formed inside the base 5a and the sandwiching pieces 5b and 5c. And the base 5a and the clamping pieces 5b and 5c are gripped in a state in which both end portions of the peripheral wall 2a of the pipe 2 are fitted over the entire circumference.

  At that time, the pipe clamp 5 is in a state where the pipe 2 is simply gripped, that is, without tightening the fastening bolts 5f for fastening the flange portions 5d and 5e formed at the tip portions of the sandwiching pieces 5b and 5c. When the tight binding is released, the pipe 2 is allowed to turn around the axis, and when the pipe 2 is tightly fastened by the fastening bolt 5f, the pipe 2 is prevented from turning around the axis.

  As described above, in the present embodiment, the case where the pipe clamp 5 is used to fasten the pipe 2 by fastening the fastening bolt 5f is shown, but the pipe 2 is gripped loosely, As long as the rotation around the axis of the pipe 2 is prevented and the rotation around the axis of the pipe 2 is allowed in a state where the binding is released, a pipe clamp having another structure can be used. As shown in FIG. 3, it is also possible to use a pipe clamp 5 configured to hold the pipe 2 by locking the tip portions 5g and 5h of the holding pieces 5b and 5c.

  Further, in order to reliably prevent the rotation of the pipe 2 around the axis in a tightly bound state, a non-slip member (not shown) can be interposed between the pipe clamp 5 and the wall surface 2a of the pipe 2. As the anti-slip member, for example, a rubber member can be used. For example, the anti-slip member can be interposed by sticking a rubber sheet to the inner peripheral surface of the base 5a of the pipe clamp 5 or the sandwiching pieces 5b, 5c. . More simply, for example, rubber bands may be hung on both end portions of the peripheral wall 2 a of the pipe 2, and the pipe 2 may be gripped by the pipe clamp 5 together with the rubber band.

  Furthermore, in this embodiment, since the cylindrical pipe 2 is gripped by the pipe clamp 5 as it is, the pipe 2 is in a state where the binding is released, as shown in FIG. It can be rotated around the axis O at an arbitrary angle θ.

  However, as shown in FIG. 4B, for example, a plurality of concave portions 5i are formed in the base portion 5a and the sandwiching pieces 5b and 5c of the pipe clamp 5, and convex portions 2b are formed at both end portions of the peripheral wall 2a of the pipe 2, respectively. The pipe 2 is formed so as to be rotated about its axis stepwise by changing the concave portion 5i of the pipe clamp 5 into which the convex portion 2b of the pipe 2 is inserted. It becomes possible.

  For example, as shown in FIG. 4C, both end portions of the peripheral wall 2a of the pipe 2 are formed in a regular polygonal shape, and the base portion 5a of the pipe clamp 5 and the inner peripheral surface portions of the sandwiching pieces 5b and 5c are complementary thereto. Even if it is formed into a regular polygonal shape, the pipe 2 can be formed in the same manner as described above by changing each surface of the regular polygonal shape of the pipe clamp 5 corresponding to each surface of the regular polygonal shape of the pipe 2. The pipe clamp 5 can be arranged by being rotated stepwise around its axis.

  In the above case, simply by releasing the binding of the pipe clamp 5 to the pipe 2, the convex portion 2b of the pipe 2 cannot be easily detached from the concave portion 5i of the pipe clamp 5, or the corresponding surfaces of the pipe 2 and the pipe clamp 5 can be easily removed. In some cases, the pipe 2 cannot be easily rotated with respect to the pipe clamp 5. In such a case, for example, the sandwiching pieces 5b and 5c of the pipe clamp 5 are configured to be further expanded, and the sandwiching pieces 5b and 5c of the pipe clamp 5 are expanded to release the binding. It is also possible to configure to allow rotation around the axis.

  In addition, it is set as the structure which reversely arranges the unevenness | corrugation in FIG.4 (B), provides a convex part in the pipe clamp 5 side, and selects suitably one recessed part among several recessed parts provided in the pipe 2 side. Is also possible. 4B and 4C show the case where the pipe 2 is configured to be rotatable with respect to the pipe clamp 5 in increments of 60 °. However, the present invention is not limited to this. By arbitrarily changing the polygonal shape, the pipe 2 can be configured to rotate stepwise at a desired angular increment.

  As shown in FIG. 1, a substrate 6 and a light source 7 are disposed inside the pipe 2. Although not shown, the substrate 6 is provided with electronic parts and the like necessary for turning on the light source 7. The electronic parts and the like are externally connected via the connector 4 and the wiring cables 8 and 9 described above. Electric power is supplied, and a signal instructing to turn on and off the light source 7 is transmitted.

  Further, in the present embodiment, as shown in FIG. 5, the substrate 6 is fixed to the peripheral wall 2 a of the pipe 2 via the support member 10, and the substrate 6 is also piped in accordance with the rotation around the axis of the pipe 2. It rotates around the axis of 2. Note that the substrate 6 may be configured to be fixed to the cap 3 described above.

  A plurality of light sources 7 are arranged on one side of the substrate 6, and light emitted from the light sources 7 passes through the peripheral wall 2 a of the pipe 2 and is emitted to the outside. In the present embodiment, an LED (Light Emitting Diode) is used for the light source 7. The LED has a long life, has excellent visibility that the light emitted by the LED can be visually recognized regardless of day and night, and has characteristics such as low power consumption.

  Further, as shown in FIGS. 6A and 6B, an irradiation field of light emitted from the light source 7 can be obtained by using a lens for the LED that is the light source 7 or by appropriately adjusting the arrangement position of the LED. R can be widened (see FIG. 6A) or narrowed (see FIG. 6B).

  In the present embodiment, the substrate 6 on which the light sources 7 are arranged is fixed inside the pipe 2 in a so-called bare state. Since the pipe 2 is transparent, the bare substrate 6 can be seen from the outside. Therefore, from the viewpoint of the appearance design of the lighting device 1, for example, the substrate 6 is accommodated in a case or the like in a state in which the light emission from the light source 7 is not blocked, or the pipe 2 on the support member 10 side of the substrate 6. It is also possible to form a blindfold by painting the inner and outer surfaces of the peripheral wall 2a, attaching a film or the like, or applying a frosted glass-like process.

  Next, the effect | action of the illuminating device 1 which concerns on this embodiment is demonstrated.

  Electric power is supplied to the substrate 6 of the lighting device 1 via the connector 4 and the wiring cables 8 and 9, and the light source 7 is transmitted to the substrate 6 of the lighting device 1 by transmitting a signal instructing turning on / off or blinking of the light source 7 7 can be turned on, turned off, or blinked. At this time, which light source 7 should be turned on, turned off, or blinked at what timing may be sequentially instructed by the signal, or may be set in advance on the substrate 6 side.

  Further, the radiation angle of the light source 7 can be adjusted as follows. As shown in FIGS. 6A and 6B, the irradiation field R of the light emitted from the light source 7 can be widened or narrowed. In this case, as shown in FIG. 7, for example, an angle θi formed between a reference surface such as a surface E parallel to the ground and the normal direction of the substrate surface of the substrate 6 indicated by an arrow L in the drawing.

  In adjusting the radiation angle, if the pipe 2 is not attached to the pipe clamp 5, both end portions of the pipe 2 are inserted between the base portion 5a of the pipe clamp 5 and the sandwiching pieces 5b and 5c, respectively. Then, the pipe 2 is arbitrarily rotated around the axis in a state where the fastening to the pipe 2 is released without tightening the fastening bolt 5f, or in the case shown in FIGS. 4B and 4C, the pipe 2 Is rotated stepwise around the axis with respect to the pipe clamp 5 to adjust the angle θ around the axis O of the pipe 2 with respect to the pipe clamp 5 shown in FIG.

  Since the substrate 6 is fixed inside the pipe 2, the change amount θθ of the angle of the pipe 2 with respect to the pipe clamp 5 is changed to the change amount θi of the angle θi with respect to the reference plane in the normal direction L of the substrate surface of the substrate 6. Will be equal. Therefore, by adjusting the angle θ around the axis of the pipe 2 with respect to the pipe clamp 5 by rotating the pipe 2 around the axis, the radiation angle θi of the light emitted from the light source 7 can be easily adjusted.

  Then, after rotating the pipe 2 around the axis and adjusting the radiation angle θi of the light source 7, the pipe 2 is fastened by tightening the fastening bolt 5f of the pipe clamp 5, and the pipe 2 is prevented from turning around the axis. As a result, the radiation angle θi of the light source 7 is determined.

  At this time, in this embodiment, as shown in FIG. 8A, the hatched portions of both end portions of the peripheral wall 2a of the pipe 2 are the base portion 5 and the sandwiching piece 5b of the pipe clamp 5 not shown. 5c is externally fitted over the entire circumference, and the fastening wall 5a is clamped so that the peripheral wall 2a of the pipe 2 has a predetermined maximum static frictional force (maximum frictional force) with the base 5 of the pipe clamp 5, etc. Is done.

On the other hand, in the conventional illumination device 100 shown in FIG. 12, as shown in FIG. 8 (B), the circumferential surface portion of the support shaft 101 shown by hatching in the drawing is a support arm portion not shown. The radiating surface 103 is fixed so as not to rotate around the axis O ^* by being gripped by a state 102 having a predetermined maximum static frictional force.

In this state, when the stone S the like which has been flying collide, in the conventional lighting apparatus 100 shown in FIG. 8 (B), since the radius R ₂ of the support shaft 101 is small, the support shaft 101 and the support arms 102 Even if the maximum static friction force is large, if the torque around the axis O ^* generated on the radiation surface 103 due to the collision of the stone S or the like is large, the torque represented by the product of the maximum static friction force and the radius R ₂ of the support shaft 101 And the radiation surface 103 is rotated around the axis O ^* by the collision of the stone S or the like. Therefore, the radiation angle changes relatively easily.

In contrast, in the illumination apparatus 1 of the present embodiment shown in FIG. 8 (A), the maximum static frictional force by the pipe clamp 5 is very large, since larger radius R ₁ of the pipe 2, the pipe due to a collision, such as a stone S 2 does not exceed the torque represented by the product of the maximum static frictional force and the radius R _{1 of the} pipe 2, and the pipe 2 remains around the axis O even if a stone S or the like collides with it. Does not rotate. Therefore, the radiation angle θi of the light source 7 (not shown) is reliably maintained.

  As described above, according to the illuminating device 1 according to the present embodiment, the light source 7 is fixed inside the transparent pipe 2 having a relatively large radius, and both ends of the pipe 2 are fastened by the pipe clamp 5 and gripped. Since it functions so that the pipe 2 does not easily rotate even if a flying stone S or the like collides with the pipe 2, the radiation angle θi of the light source 7 is applied even when an impact is applied. That is, it is possible to reliably maintain the light emission direction.

  Normally, the pipe 2 can be tightly bound by the pipe clamp 5 to such an extent that, for example, an operator or the like grasps the pipe 2 and tries to rotate it around the axis O. Since it can be strongly bound in this way, according to the illuminating device 1 according to the present embodiment, not only the impact of the collision of the stone S or the like, but also the light emission direction can be ensured even when a stronger impact is applied. Maintained.

  Moreover, according to the illuminating device 1 which concerns on this embodiment, it becomes possible to rotate the pipe 2 around the axis | shaft O easily by canceling | releasing the binding of the pipe clamp 5. FIG. Therefore, the radiation angle θi of the light source 7, that is, the light radiation direction can be easily and appropriately adjusted.

  Furthermore, the pipe 2 including the light source 7 and the like can be easily replaced by releasing the binding of the pipe clamp 5, and the pipe 2 can be easily held by holding the pipe 2 with the pipe clamp 5. Can be attached.

  Needless to say, the arrangement of the light sources 7 on the substrate 6 is not limited to the arrangement shown in FIG. Moreover, the illuminating device 1 which concerns on this embodiment has versatility as mentioned above, and alerts so that the passenger P may not fall from the clearance gap G between the platform H and the rail vehicle C as mentioned above. It is not limited when used for a home fall warning device.

  Moreover, although this embodiment demonstrated the case where the illuminating device 1 was installed in the ground etc. so that the axis O direction of the pipe 2 may face a horizontal direction, it is not limited to this, The axis O direction of the pipe 2 May be arranged so as to face the vertical direction, and the pipe 2 can be arranged so as to be inclined with respect to the vertical direction. Furthermore, it is also possible to install the illuminating device 1 on a floor surface, a ceiling, an indoor or outdoor wall surface, a pillar, or the like.

  Further, in the present embodiment, as shown in FIGS. 6A and 6B, the lighting device 1 that emits light in a specific direction or a specific irradiation field R has been described. In addition, for example, as shown in FIG. 9, a plurality of substrates 6 a to 6 c on which light sources 7 are arranged are provided inside the pipe 2 of the lighting device 1 so that light is emitted in all directions around the pipe 2. Is also possible.

  Moreover, although this embodiment demonstrated on the assumption that visible lights, such as yellow, were radiated | emitted, the light radiated | emitted from the illuminating device 1 is not limited to visible light.

[Home fall warning device]
Next, an embodiment of the home fall warning device of the present invention using the lighting device 1 will be described.

  In the home fall warning device according to the present embodiment, a plurality of the above-described lighting devices 1 are disposed below the platform H as shown in FIG. Each lighting device 1 is disposed below each door of the railway vehicle C so as to illuminate at least the vicinity of the lower part of the door of the railway vehicle C among the portions of the side wall of the railway vehicle C close to the platform H from below. The angle θ around the axis of the pipe 2 is adjusted.

  In addition, when there is no space for the lighting device 1 to be disposed below the platform H, for example, as shown in FIG. The apparatus 1 may be disposed.

  At that time, as shown in FIG. 4 (B) and FIG. 4 (C) described above, the lighting apparatus 1 is arranged by rotating the pipe 2 stepwise around the axis with respect to the pipe clamp 5. If the angle θ around the axis of the pipe 2 of each lighting device 1 is aligned at a predetermined stage position, the radiation angles θi of all the lighting devices 1 can be easily aligned. It becomes.

  FIG. 11 is a block diagram showing a control configuration of the home fall warning device according to the present embodiment. The home fall warning device 20 includes the plurality of lighting devices 1 described above, vehicle detection means 21, and control means 22. Further, in the present embodiment, a monitoring panel 23 that displays the operation of the lighting device 1, a failure location, and the like is further connected to the control means 22.

  In the following, a case will be described in which lighting devices 1 are provided on both the upstream and downstream lines of one platform H shown in FIG. 11, but the present invention is not limited to this, and the platform H is not limited thereto. The present invention is also applicable to the case where the lighting device 1 is provided only on one side or the case where the lighting device 1 is provided on each of the plurality of platforms H.

  As the vehicle detection means 21, for example, a detection sensor that detects a reflected vehicle by emitting a laser beam, an ultrasonic wave, or the like to detect a railway vehicle C entering or stopping on the up or down line of the platform H may be used. it can.

  In addition, a railroad track is provided with an interlocking device that detects the position of the railcar C on the railroad and detects the status of the railcar C. The interlocking device can be used as the vehicle detection means 21. it can. The rail of the railway is insulated for each predetermined track (section), which is short-circuited by the wheels of the railway vehicle C. The interlocking device detects where the railway vehicle C is currently located by detecting the short circuit.

  When the railway vehicle C stops at the position of the up line or down line of the platform H, it enters one track (hereinafter referred to as a home truck), but it detects that the railway vehicle C is on the home track. Thus, information transmitted from the interlocking device can be used as a detection signal.

  The control means 22 is constituted by a computer having a CPU, ROM, RAM, input / output interface, etc. (not shown) connected to the bus, and receives a detection signal detected and transmitted by the vehicle detection means 21 such as a detection sensor or interlocking device. Then, based on this, a lighting signal is transmitted to each lighting device 1 on the side where the entry or stop of the railway vehicle C of the platform H is detected, and each lighting device 1 is turned on.

  In addition, when the detection signal from the vehicle detection unit 21 is no longer input, the control unit 22 stops transmitting the lighting signal to each lighting device 1 that is turned on, and turns off each lighting device 1. ing. Note that the control means 22 may be configured by using, for example, an FPGA (Field Programmable Gate Array) instead of using a computer, or by using a so-called sequencer.

  As described above, according to the home fall warning device 20 according to the present embodiment, as described above, the pipe 2 does not easily rotate due to the impact of the stone S or the like on which the lighting device 1 flies, and is difficult to break. Therefore, the light emission direction is maintained so that at least the vicinity of the lower part of the door of the railway vehicle C is continuously illuminated accurately.

  Therefore, even when time elapses after each lighting device 1 is attached, the light emission direction does not change or the pipe 2 does not break, and each time the railway vehicle C stops on the platform H, the door It is possible to reliably illuminate the vicinity of the lower part of the vehicle and to inform the passenger P of the existence of the gap G between the platform H and the railway vehicle C so that the passenger P does not fall into the gap G.

  Moreover, since the illuminating device 1 can be installed not only on a horizontal surface such as the ground but also on an upright surface such as a wall surface, even when there are structural restrictions on the platform H, the illuminating device 1 is appropriately arranged to transmit light. By appropriately adjusting the radiation direction, it is possible to radiate light to a necessary place such as near the lower side of the door of the railway vehicle C.

  Furthermore, since it becomes possible to accurately detect that the railway vehicle C has entered and stopped on the platform H by the detection sensor, the interlocking device, or the like as the vehicle detection means 21, it is possible to accurately turn on the lighting device 1 to be turned on. Even if the railway vehicle C does not enter the platform H, it is possible to prevent the lighting device 1 from turning on and causing the passengers P to feel uncomfortable, and it is possible to suppress wasteful power consumption. Become.

  In addition, it is also possible to radiate light near the lower part of the door of the railway vehicle C parked on the platform H, and at the same time, for example, to utter a voice that alerts the passenger P.
