Summary of the Invention

Problems to be Solved by the Invention

[0004] For an operator performing loading or unloading operations of goods, it is important that the loading platform lifted by the loading platform lifting device is easily visible. For example, when an operator moves goods from the loading platform into the loading platform, if the operator does not recognize the tip position or side end position of the loading platform, there is a risk that the goods will slide off the end of the loading platform. In particular, when working in a dark place at night or the like, it is important that the operator can easily visually recognize the tip position or side end position of the loading platform.

[0005] Furthermore, even if the loading platform is equipped with a stopper to prevent the load from sliding off, as disclosed in Patent Document 3, if the stopper is not upright but remains in a reclined state, the load may not be stopped by the stopper when the worker moves the load from the loading platform to the loading platform, and the load may slide off the loading platform. Therefore, it is important that the worker can easily see whether the stopper on the loading platform is upright or reclined. This is especially important when working in dark places such as at night.

[0006] Furthermore, since the loading platform is raised and lowered between the floor of the cargo vehicle's loading platform and the ground, it is important that its presence is easily visible to people around it, such as pedestrians. In particular, in dark places such as at night, there is a risk of people around the loading platform tripping over or colliding with it, so it is important that people around the loading platform can easily see the front and side edges of the loading platform.

[0007] This invention was conceived in view of the above-mentioned problems, and aims to provide a loading platform that allows workers to easily see the front and side ends of the loading platform even in dark places.

[0008] Furthermore, the present invention aims to provide a loading platform that allows workers to easily see the state of the stopper even in dark places.

[0009] Furthermore, the present invention aims to provide a loading platform that allows people standing around it to easily see the front and side edges of the loading platform, even in dark places. [Means for solving the problem]

[0010] A loading platform according to a first aspect of the present invention is a loading platform that is raised and lowered between the floor of the loading platform of a cargo vehicle and the ground by a loading platform lifting device provided on the cargo vehicle, and comprises a loading platform body and a light-emitting element provided on the side surface of the loading platform body. The loading platform body has a general part and a front end part provided on the front end side of the general part and having a loading surface that is inclined toward the ground toward the rear of the vehicle than the loading surface of the general part. The light-emitting element is provided on the side surface of the front end part of the loading platform body.

[0011] In a loading platform with such a configuration, the light-emitting element is located on the side of the front end portion, which is positioned further forward than the general portion of the loading platform body. Therefore, even in dark places, workers can easily see the front end and side end positions of the loading platform.

[0012] Furthermore, with a loading platform having such a configuration, the light-emitting element is provided on the side of the front end portion, which is located further forward than the general portion of the loading platform body. This makes it easier for people around the loading platform to see the front end and side end positions of the loading platform even in dark places.

[0013] A loading platform according to a second aspect of the present invention is a loading platform that is raised and lowered between the floor of the loading platform of a cargo vehicle and the ground by a loading platform lifting device provided on the cargo vehicle, and comprises a loading platform body and a light-emitting element provided on the side surface of the front end of the loading platform body.

[0014] With a loading platform having such a configuration, the light-emitting element is provided on the side of the leading edge of the loading platform body, making it easy for workers to see the leading edge and side edges of the loading platform even in dark places.

[0015] Furthermore, with a loading platform having such a configuration, since the light-emitting element is provided on the side of the leading edge of the loading platform body, people around the loading platform can easily see the leading edge and side edges of the loading platform even in dark places.

[0016] A third aspect of the present invention is a loading platform that is raised and lowered between the floor of the loading platform of a cargo vehicle and the ground by a loading platform lifting device provided on the cargo vehicle, comprising: a loading platform body; a stopper provided on the loading platform body that can change its posture between an upright position protruding from the loading surface of the loading platform body and a reclined position that constitutes a part of the loading surface; and a light-emitting element provided on the side surface of the loading platform body such that its position in the front-rear direction is close to or overlaps with the stopper when it is protruding above the loading surface.

[0017] With a loading platform having such a configuration, since the light-emitting element is provided on the side of the loading platform body, workers can easily see the side edge of the loading platform even in dark places.

[0018] Furthermore, in a loading platform with such a configuration, the light-emitting element is provided on the side of the loading platform body so that its position in the front-to-back direction is close to or overlaps with the stopper, which protrudes above the loading surface. Therefore, even in dark places, workers can easily see whether the stopper is standing upright or not.

[0019] Furthermore, with a loading platform having such a configuration, since the light-emitting element is provided on the side of the loading platform body, it is easy for people standing around the loading platform to see the side edge of the loading platform even in dark places.

[0020] A loading platform according to a fourth aspect of the present invention is a loading platform that is raised and lowered between the floor of the loading platform of a cargo vehicle and the ground by a loading platform lifting device provided on the cargo vehicle, and is provided on the side of the loading platform opposite to the loading surface and includes a light-emitting element that emits light outward in the vehicle width direction.

[0021] In a loading platform with such a configuration, a light-emitting element that emits light outward in the vehicle width direction is provided on the side of the loading platform opposite to the loading surface, making it easier for people around the loading platform to see the side edge position even in dark places. [Effects of the Invention]

[0022] According to the present invention, it is possible to provide a loading platform that allows workers and people around the loading platform to easily visually recognize the tip position and side end position of the loading platform even in a dark place.

[0023] Also, according to another aspect of the present invention, it is possible to provide a loading platform that allows a worker to easily visually recognize the state of a stopper even in a dark place.

[0024] Furthermore, according to yet another aspect of the present invention, it is possible to provide a loading platform that allows people around the loading platform to easily visually recognize the side end position of the loading platform even in a dark place.

[0026] <First Embodiment> A loading platform 10 according to the first embodiment of the present invention will be described. First, the cargo vehicle 1, the loading platform 10, and the loading platform lifting device 100 will be briefly described with reference to the drawings. In this specification, the directions of front, rear, left, right, up, and down will be defined with respect to the cargo vehicle 1.

[0027] As shown in Figure 1, the cargo vehicle 1 consists of a cargo bed D, a loading platform 10, a loading platform lifting device 100, and the like.

[0028] Cargo bed D is mounted on top of the chassis frame of cargo vehicle 1.

[0029] (Loading platform lifting device) The loading platform lifting device 100 is a lifting device installed on a cargo vehicle 1 that assists in the work of unloading cargo (not shown) from the loading platform D and loading cargo onto the loading platform D. The loading platform lifting device 100 has a pair of left and right posts 40 erected at the rear end of the loading platform D of the cargo vehicle 1, a slider 41 configured to move up and down along the posts 40, and a drive device (not shown) that drives the slider 41 in the vertical direction. The loading platform 10 is supported by the slider 41 and moves up and down as the slider 41, driven by the drive device, moves up and down.

[0030] As shown in Figure 1, the loading platform 10 is used by switching between an upright state and a horizontal state. In the upright state, the loading platform 10 is positioned to cover the rear of the loading platform D. The loading platform 10 can be switched from the upright state to the horizontal state by an operator rotating the lock lever 15 (shown in Figures 2 and 3) from the base end of the loading platform 10 (downward in the upright state) to the front end of the loading platform 10 (upward in the upright state). The loading platform 10 is then manually moved to the horizontal state by the operator and becomes a horizontal platform positioned at the same height as the bottom of the loading platform D.

[0031] Furthermore, the loading platform 10 descends from the height of the bottom of the loading platform D to the ground while maintaining a horizontal position, by a slider 41 driven by a drive unit along a pair of left and right posts 40. This movement assists workers in unloading goods from the loading platform D. At this time, the pair of left and right posts 40 extend to near the ground. When workers load goods onto the loading platform D, the loading platform 10 performs the reverse movement.

[0032] (Loading platform) As shown in Figures 2 and 3, the loading platform 10 includes a loading platform body 11, a grounding member 14, and a light-emitting element 20a.

[0033] The loading platform body 11 is a substantially plate-shaped member that forms the loading surface 11a of the loading platform 10. The loading platform body 11 has a general section 12 and a front end section 13 that is continuously provided on the front end side (rear end of the vehicle) of the general section 12. The general section 12 has a substantially horizontal loading surface 11a1 (11a). The loading surface 11a2 (11a) of the front end section 13 is inclined towards the ground towards the rear of the vehicle more than the loading surface 11a1 (11a) of the general section 12. In other words, the front end section 13 is a part that has a tapered shape at the front end of the loading platform body 11.

[0034] A grounding member 14 is provided on the surface of the loading platform body 11 opposite to the loading surface 11a, i.e., the back surface 11c of the loading platform body 11. In the first embodiment, the grounding member 14 is made of rubber. The grounding member 14 prevents the loading platform body 11 from directly contacting the ground even when it is lowered to the ground.

[0035] The light-emitting element 20a is provided on the side surface 11b of the loading platform body 11. Specifically, as shown in Figures 2 and 3, the light-emitting element 20a is provided on the side surface 11b of the front end side portion 13 of the loading platform body 11. In this embodiment, a part of the light-emitting element 20a is provided on the side surface 11b of the front end side portion 13 of the loading platform body 11, and the other part of the light-emitting element 20a is provided on the side surface of the general portion 12 of the loading platform body 11. The light-emitting element 20a is provided on the front end side of the loading platform body 11, beyond the tip of the lock lever 15 which is positioned towards the front end of the loading platform 10.

[0036] The light-emitting element 20a is included in the light-emitting device 20. The light-emitting device 20 includes, for example, a casing 21, a solar panel 23, a battery (not shown), a substrate (not shown), and a tilt detection unit (not shown), in addition to the light-emitting element 20a, as shown in Figures 4 and 5. The light-emitting element 20a emits light and is composed of a light-emitting element 22 and a lens cover 24.

[0037] The casing 21 is formed in a roughly pentagonal shape, with the portion positioned at the front side 13 of the loading platform body 11 sloping diagonally toward the ground.

[0038] In the first embodiment, the light-emitting element 22 is an LED element. The light-emitting element 22 is powered by a battery via a substrate (not shown).

[0039] The solar panel 23 generates power from sunlight to allow the light-emitting element 22 to emit light without the light-emitting element 20a receiving power from an external source. The power generated by the solar panel 23 is stored in a battery (not shown).

[0040] A tilt detection unit, not shown in the diagram, is connected to the circuit board and detects the tilt of the light-emitting element 20a. Specifically, when the tilt detection unit detects that the loading platform 10 is upright, the circuit board stops supplying power to the light-emitting element 22, and when the tilt detection unit detects that the loading platform 10 is horizontal, the circuit board supplies power to the light-emitting element 22. As a result, the light-emitting element 20a can only emit light when the loading platform 10 is horizontal.

[0041] The lens cover 24 covers the opening portion of the casing 21, and in particular covers the light-emitting element 22 and the solar panel 23. The lens cover 24 is made of a transparent material, and in the first embodiment, it is made of acrylic resin. The lens cover 24 has a scattering portion 25 and a transparent portion 26. The scattering portion 25 is the portion that covers the light-emitting element 22 and its surrounding portion, and scatters the light emitted by the light-emitting element 22 outward in the vertical direction, the front-rear direction of the vehicle, and the width direction of the vehicle. The transparent portion 26 is the portion that covers the solar panel 23 and transmits light without refraction or scattering.

[0042] (Effects and Benefits) According to the first embodiment of the loading platform 10 described above, since the light-emitting element 20a is provided on the side surface 11b of the front end side portion 13 of the loading platform body 11, workers can easily see the front end position and side end position of the loading platform 10 even in dark places.

[0043] Furthermore, according to the first embodiment of the loading platform 10, since the light-emitting element 20a is provided on the side surface 11b of the front end side portion 13 of the loading platform body 11, it is easy for people standing around the loading platform to see the front end and side end positions of the loading platform 10 even in the dark, thus preventing people standing around the loading platform 10 from tripping over or colliding with the front end or side end of the loading platform 10.

[0044] Furthermore, according to the first embodiment of the loading platform 10, since it is provided on the side surface 11b of the front side portion 13 which has a loading surface 11a2 that slopes toward the ground toward the rear of the vehicle, the position of the front side portion 13 where the orientation of the load changes when the worker moves the load on the loading surface 11a1, 11a2 can be easily seen by the worker even in the dark.

[0045] <Second Embodiment> Next, a loading platform 10A according to the second embodiment will be described. In the following, for each embodiment, only the differences from the loading platform 10 according to the first embodiment will be described, and parts that perform the same function as parts of the loading platform 10 will be described using the same names and reference numerals.

[0046] The loading platform 10A according to the second embodiment is raised and lowered between the floor of the loading platform D of the cargo vehicle 1 and the ground by a loading platform lifting device 100 provided on the cargo vehicle 1, along a pair of posts 40 erected on the cargo vehicle 1.

[0047] As shown in Figures 6 and 7, the loading platform 10A includes a loading platform body 11A and a light-emitting element 20Aaa.

[0048] The loading platform body 11A has a different shape at its tip portion 13A compared to the loading platform body 11 according to the first embodiment. Specifically, the loading surface 11Aa of the loading platform body 11A does not have a loading surface 11a2 that slopes toward the ground, like the tip side portion 13 of the loading platform body 11 according to the first embodiment. That is, the loading surface 11Aa of the loading platform body 11A is formed along a single plane from the base end to the tip end, and when the loading platform body 11A descends and the grounding member 14 touches the ground, a step difference corresponding to the thickness of the loading platform body 11A is created between the loading surface 11Aa and the ground.

[0049] The light-emitting element 20Aa is provided on the side surface 11Ab of the tip portion 13A of the loading platform body 11A. The light-emitting element 20Aa has the same components as the light-emitting element 20a according to the first embodiment, but the shape of the lens cover 24 is substantially rectangular and is formed to conform to the shape of the tip portion 13A of the loading platform body 11A.

[0050] (Effects and Benefits) According to the second embodiment of the loading platform 10A described above, since the light-emitting element 20Aa is provided on the side surface 11Ab of the front end 13A of the loading platform body 11A, workers can easily see the front end position and side end position of the loading platform 10A even in dark places.

[0051] Furthermore, according to the second embodiment of the loading platform 10A, since the light-emitting element 20Aa is provided on the side surface 11Ab of the front end 13A of the loading platform body 11A, it is easier for people around the loading platform to see the front end and side end positions of the loading platform 10A even in dark places.

[0052] Furthermore, according to the second embodiment of the loading platform 10A, a light-emitting element 20Aa is provided on the side surface 11Ab of the front end 13A of the loading platform body 11A, making it easy to see the position of the front end 13A and the side end of the loading platform body 11A even in the dark. Also, when the loading platform body 11A is in contact with the ground, the light-emitting element 20Aa is provided on the side surface 11Ab of the front end 13A of the loading platform body 11A where the loading surface 11Aa creates a step between it and the ground, making it easy for workers to see the position of the step where the orientation of the load changes when loading a load onto the loading platform body 11A, even in the dark.

[0053] <Third Embodiment> Next, the loading platform 10B according to the third embodiment will be described. First, the cargo vehicle 1B, the loading platform 10B, and the loading platform lifting device 100B in the third embodiment will be briefly described with reference to the drawings.

[0054] As shown in Figure 8, the cargo vehicle 1B consists of a cargo bed DB, a loading platform 10B, a loading platform lifting device 100B, a rear bumper B, and the like.

[0055] In the third embodiment, the cargo bed DB forms the bottom of a roughly rectangular cargo box with an opening at the rear. The rear opening of the cargo box is opened and closed by a door. For example, double doors or upper and lower doors are used as the doors that open and close the rear opening of the cargo box. Double doors consist of a left door that opens and closes the left side of the rear opening of the cargo box and a right door that opens and closes the right side of the rear opening of the cargo box. The left and right doors are attached to the left and right sides of the cargo box, respectively, via hinges having vertically extending pivot axes, and are attached to the cargo box so as to open from the center to both sides. Upper and lower doors consist of an upper door that opens and closes the upper side of the rear opening of the cargo box and a lower door that opens and closes the lower side of the rear opening of the cargo box. The upper end of the upper door is attached to the upper end of the cargo box via a hinge having a pivot axis extending in the vehicle width direction, and the cargo receiving platform 10B acts as the lower door.

[0056] The rear bumper B is joined to a subframe (not shown) to which the loading platform lifting device 100B is attached, via stays. The rear bumper B is divided into three sections in the vehicle width direction, and the arm device 50 of the loading platform lifting device 100, described later, passes through each gap.

[0057] (Loading platform lifting device) The loading platform lifting device 100B is a lifting device installed on the cargo vehicle 1B. The loading platform lifting device 100B has a pair of left and right arm devices 50 that are supported on the cargo vehicle 1B so as to be able to rotate up and down, and a hydraulic device (not shown) that drives the arm devices 50. The loading platform 10B is supported on the tip sides of the pair of arm devices 50, and as the arm devices 50 rotate up and down, the loading platform 10B moves up and down between the floor surface of the loading platform DB of the cargo vehicle 1B and the ground.

[0058] As shown in Figure 8, the loading platform 10B is used by switching between an upright state and a horizontal state. In the upright state, the loading platform 10B is positioned to cover the rear of the loading platform DB. The loading platform 10B is moved from the upright state to the horizontal state by the arm device 50, becoming a horizontal platform positioned at the same height as the floor surface of the loading platform DB. Furthermore, the loading platform 10B is lowered by the arm device 50 from the height of the floor surface of the loading platform DB to near the ground while maintaining a horizontal state, and then tilts so that its tip touches the ground. This movement allows the loading platform 10B to assist workers in unloading cargo from the loading platform DB. When workers load cargo into the loading platform DB, the loading platform 10B performs the reverse movement. In this way, the loading platform 10B is raised and lowered between the floor surface of the loading platform DB and the ground. The configuration of the loading platform 10B will be described later.

[0059] Each of the left and right arm devices 50 has a pivot arm whose base end is supported by the chassis frame (not shown) of the cargo vehicle 1B and whose tip end is provided to be rotatable vertically, and a hydraulic cylinder connected to the pivot arm. The base end of the pivot arm is rotatably supported by a subframe connected to the chassis frame. The hydraulic cylinder is supplied with and discharged pressurized oil by a hydraulic system. As a result, the pivot arm is driven by the hydraulic cylinder. The hydraulic system has a hydraulic pump, which is operated by the operator. A loading platform 10B is connected to the tip of the pivot arm. The pivot arm consists of multiple arms that form a parallel link. The link mechanism of the pivot arm driven by the hydraulic cylinder enables the movement of the loading platform 10B.

[0060] (Loading platform) As shown in Figures 9 and 10, the loading platform 10B includes a loading platform body 11B, a stiffener 16, a stopper 17, and a light-emitting element 20Ba.

[0061] The loading platform body 11B is a substantially plate-shaped member that forms the loading surface 11Ba of the loading platform 10B. The material used for the loading platform body 11B is not particularly limited, but in this embodiment, the loading platform body 11B has a known configuration in which a plurality of hollow aluminum alloy members are assembled together with the vehicle width direction as the longitudinal direction.

[0062] The stiffener 16 is provided on the underside 11Bc of the loading platform body 11B, and reinforces the loading platform body 11B from the underside. The stiffener 16 is formed in a roughly triangular shape when viewed in the vehicle width direction, and when the loading platform 10B is in contact with the ground, the stiffener 16 comes into contact with the ground.

[0063] The stopper 17 is a roughly plate-shaped member that extends in the vehicle width direction. The stopper 17 is provided on the loading platform body 11B so as to be able to change its posture between an upright position protruding from the loading surface 11Ba of the loading platform body 11B and a reclined position forming part of the loading surface 11Ba. Specifically, the stopper 17 can be switched between an upright state, where it stands above the loading surface 11Ba of the loading platform body 11B, and a reclined state, where it is aligned with the loading surface 11Ba of the loading platform body 11B, by rotating the front side of the vehicle up and down. The stopper 17 is provided near the tip of the loading platform body 11B, that is, near the rear end of the vehicle in the horizontal position of the loading platform body 11B. Although not shown, the loading platform body 11B has a storage space where the stopper 17 is stored when it is in the reclined state.

[0064] The light-emitting element 20Ba is provided on the side surface 11Bb of the loading platform body 11B, such that it is close to or overlaps with the stopper 17 which protrudes above the loading surface 11Ba, that is, the stopper 17 which is in an upright position. Hereinafter, "close to" means that the distance between the light-emitting element 20Ba and the stopper 17 in the front-rear direction is any value within the range of 0 mm to 20 mm.

[0065] The light-emitting element 20Ba is included in the light-emitting device 20B. As shown in Figures 11 and 12, the light-emitting device 20B includes, in addition to the light-emitting element 20Ba, a casing 21B, a solar panel 23B, a battery (not shown), a substrate (not shown), and a tilt detection unit (not shown). The light-emitting element 20Ba according to the third embodiment emits light and is composed of a light-emitting element 22 and a lens cover 24B. However, the lens cover 24B differs from the lens cover 24 of the light-emitting element 20a according to the first embodiment only in shape and size, so a detailed explanation is omitted. Similarly, the casing 21B and solar panel 23B of the light-emitting device 20B differ from the casing 21 and solar panel 23 of the light-emitting device 20 according to the first embodiment only in shape and size, so a detailed explanation is omitted.

[0066] (Effects and Benefits) According to the third embodiment of the loading platform 10B described above, since the light-emitting element 20Ba is provided on the side surface 11Bb of the loading platform body 11B, workers can easily see the side end position of the loading platform 10B even in dark places.

[0067] Furthermore, according to the third embodiment of the loading platform 10B, the light-emitting element 20Ba is provided on the side surface 11Bb of the loading platform body 11B such that its position in the front-to-back direction is close to or overlaps with the stopper 17 in the upright position. Therefore, even in dark places, it is easy for workers to recognize (visually confirm) whether or not the stopper 17 is upright.

[0068] Furthermore, according to the third embodiment of the loading platform 10B, the light-emitting element 20Ba is provided on the side surface 11Bb of the loading platform body 11B such that its position in the front-to-back direction is close to or overlaps with the stopper 17 in the upright position. This makes it easier for workers to see the position of the stopper 17 that holds the load when moving the load on the loading surface 11a, even in the dark.

[0069] Furthermore, according to the third embodiment of the loading platform 10B, since the light-emitting element 20Ba is provided on the side surface 11Bb of the loading platform body 11B, it is easier for people standing around the loading platform 10B to see the side edge of the loading platform 10B even in the dark, thus preventing people standing around the loading platform 10B from tripping over or colliding with the side edge of the loading platform 10B.

[0070] <Fourth Embodiment> Next, the loading platform 10C according to the fourth embodiment will be described. First, the cargo vehicle 1C and the loading platform 10C in the fourth embodiment will be briefly described with reference to the drawings.

[0071] As shown in Figure 13, the cargo vehicle 1C consists of a cargo bed DB, a loading platform 10C, a loading platform lifting device 100B, a rear bumper B, etc. The cargo bed DB, the loading platform lifting device 100B, and the rear bumper B are the same as those described in the third embodiment, so their description is omitted.

[0072] The loading platform 10C, like the loading platform 10B according to the third embodiment, is supported on the tip side of a pair of arm devices 50 of the loading platform lifting device 100B, and as the arm devices 50 rotate up and down, the loading platform 10C moves up and down between the floor surface of the loading platform DB of the cargo vehicle 1C and the ground.

[0073] (Loading platform) As shown in Figures 14 and 15, the loading platform 10C includes a loading platform body 11B, a stiffener 16, a stopper 17, a bracket 18, and a light-emitting element 20Ca. Of these, the loading platform body 11B, the stiffener 16, and the stopper 17 are the same as those described in the third embodiment, so their description is omitted.

[0074] Although the light-emitting element 20Ca has the same components as the light-emitting element 20Ba according to the third embodiment, it is installed in a different location. Specifically, the light-emitting element 20Ca is installed on the back surface 11Bc of the loading platform body 11B, opposite to the loading surface 11Ba, via a bracket 18. The light-emitting element 20Ca is installed on the back surface 11Bc of the loading platform body 11B with the direction of light emission directed outward in the vehicle width direction. As a result, even though the light-emitting element 20Ca is installed on the back surface 11Bc of the loading platform body 11B, it is possible to emit light outward in the vehicle width direction.

[0075] The bracket 18 is constructed, for example, using an angle material with an L-shaped cross-section. One side of the L-shape is bolted to the back surface 11Bc of the loading platform body 11B, and the casing of the light-emitting device, which includes the light-emitting element 20Ca, is bolted to the other side of the L-shape.

[0076] (Effects and Benefits) According to the fourth embodiment of the loading platform 10C described above, since the light-emitting element 20Ca that emits light outward in the vehicle width direction is provided on the surface 11Bc of the loading platform 10C opposite to the loading surface 11Ba, it is possible to make it easier for people standing around the loading platform 10C to see the side edge position of the loading platform 10C even in the dark, thereby preventing people standing around the loading platform 10C from tripping over or colliding with the side edge of the loading platform 10C.

[0077] (Modified version of the fourth embodiment) In the fourth embodiment, the loading platform body 11B of the loading platform 10C is made of an aluminum alloy, but the material of the loading platform body is not limited to this, and may be made of steel, for example. For example, the loading platform 10D shown in Figure 16 has a loading platform body 11D made of steel. Even in this case, the light-emitting element 20Da, which has the same configuration as the light-emitting element 20Ca in the fourth embodiment, is provided on the back surface 11Dc of the loading platform body 11D via a bracket 18. Since the light-emitting element 20Da is provided closer to the side end surface of the loading platform body 11D than the light-emitting element 20Ca in the fourth embodiment, the side end of the loading platform 10D equipped with the light-emitting element 20Da is more easily visible to people around the loading platform 10D even in the dark. Therefore, it is possible to prevent people around the loading platform 10D from tripping over or colliding with the side end of the loading platform 10D.

[0078] (Other variations) Although the five types of light-emitting elements 20a, 20Aa, 20Ba, 20Ca, and 20Da described above were all explained assuming the use of LED elements as the light-emitting element 22, the light-emitting element 22 is not limited to LED elements and may be constructed using, for example, an incandescent light bulb or a fluorescent tube.

[0079] In the first and second embodiments described above, a so-called vertical loading platform lifting device 100 equipped with a pair of left and right posts 40 was used as the device for raising and lowering the loading platform, and in the third and fourth embodiments, a loading platform lifting device 100B equipped with an arm device 50 was used as the device for raising and lowering the loading platform. However, the type of loading platform lifting device is not limited in each embodiment. That is, in the first and second embodiments, a loading platform lifting device 100B equipped with an arm device 50 may be used as the device for raising and lowering the loading platform, and in the third and fourth embodiments, a loading platform lifting device 100 equipped with a pair of left and right posts 40 may be used as the device for raising and lowering the loading platform.
