Description

[Technical field]

[0001] The present invention relates to a safety device for a vehicle having a loading platform on which luggage can be loaded and unloaded. The present invention also relates to a vehicle equipped with the safety device, and a device for lifting and lowering the loading platform of the vehicle. [Background technology]

[0002] A vehicle having a loading platform on which a cargo box is mounted and on which cargo can be loaded and unloaded is disclosed, for example, in Patent Document 1. In a vehicle having a conventional loading platform lifting device as disclosed in Patent Document 1, the loading platform assumes an operating position in which it is horizontal when loading and unloading cargo, and the cargo can be placed on the horizontal loading platform and lifted and lowered together with the loading platform.

[0003] When no cargo is being loaded or unloaded, the loading platform can be in an upright vertical position and can be placed in a standby position close to the rear of the cargo box. In the standby position, the loading platform does not protrude to the rear of the vehicle, leaving the space behind the vehicle open. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2002-114114 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when changing from the standby position to the operating position, the loading platform is located at the rear of the vehicle body, so if people nearby cannot predict the operation of the loading platform, they may come into contact with the loading platform. Also, there may be an object in the area where the loading platform is located, and the loading platform may come into contact with the object when deployed to the operating position.

[0006] Therefore, an object of the present invention is to provide a vehicle safety device capable of calling attention to the surroundings when the loading platform is deployed. Another object of the present invention is to provide a vehicle equipped with a safety device capable of calling attention to the surroundings. Still another object of the present invention is to provide a loading platform lifting device for a vehicle equipped with a safety device capable of calling attention to the surroundings. [Means for solving the problem]

[0007] A first aspect of the present invention for solving the above problems is a safety device for a vehicle having a loading platform that is positioned behind a loading platform when loading and unloading luggage from the loading platform, the loading platform taking an operating position in which it occupies the ground in a state of extending behind the loading platform when loading and unloading luggage, and taking a retracted position in which it does not occupy the ground behind the loading platform when not loading and unloading luggage, and the safety device for a vehicle having a loading platform is characterized in that it has a light irradiation device that emits a light beam that indicates the area of ​​the ground that the loading platform occupies behind the vehicle.

[0008] When loading or unloading cargo, the loading platform assumes an operational posture in which it occupies the ground with the platform extending out to the rear of the platform (disposed in the operational position), and when loading or unloading cargo, it assumes a retracted posture in which it does not occupy the ground behind the platform (retracted to the retracted position). In other words, when the loading platform assumes the retracted posture (retracted to the retracted position), a space is formed behind the platform. Therefore, it is possible for a person to enter the formed space or for an object to be placed therein. If the loading platform is disposed in the operational position in such a state, there is a risk that the loading platform may come into contact with a person or an object. According to this aspect, the loading platform has a light projection device that projects a light beam indicating the area of ​​the ground occupied behind the vehicle, so that people around the vehicle can see the ground where the light beam is projected and can avoid entering the space behind the loading platform. That is, by shining the light beam on the ground, it is possible to alert people in the vicinity to the area of ​​the ground where the light beam is shining, and when the loading platform starts to move to the operating position, the people in the vicinity can recognize that the loading platform will be located in the area where the light beam is shining. Therefore, before the loading platform completes its movement to the operating position, the people in the vicinity can move away from the area where the light beam is shining so as not to come into contact with the loading platform 7. Also, the vehicle occupant or worker can visually check whether there is an object illuminated by the irradiated light beam, and can then move the object from the area illuminated by the light beam, or move the vehicle to a location where there is no object illuminated by the light beam and perform loading and unloading of luggage. In other words, with the vehicle safety device of this aspect, the extent of the area to which the loading platform will be moved can be grasped before the loading platform changes position to the operating position, thereby ensuring safety when the loading platform is deployed from the standby position to the operating position.

[0009] It is preferable that the light irradiation device irradiates the light immediately before the load receiving platform changes its position from the retracted position to the operating position.

[0010] According to this configuration, the light irradiation device emits light just before the loading platform changes its position from the retracted position to the operating position, so that people around the vehicle can know in advance that the loading platform will be deployed from the standby position to the operating position and can avoid the area on the ground that would be occupied by the deployed loading platform.

[0011] It is preferable that the light irradiation device irradiates light onto the entire area of ​​the ground occupied by the loading platform, or onto the boundary between the area of ​​the ground occupied by the loading platform and other areas of the ground.

[0012] According to this configuration, the light emitting device emits light onto the entire area of ​​the ground occupied by the loading platform, or onto the boundary between the area of ​​the ground occupied by the loading platform and other areas of the ground, so that the range of the area occupied by the loading platform is indicated before the loading platform changes its position from the standby position to the operating position, thereby making it possible to reliably prevent the loading platform from coming into contact with people or objects in the vicinity.

[0013] It is preferable that the light projecting device projects light to display characters on the ground.

[0014] According to this configuration, a message can be conveyed to people in the vicinity by displaying letters on the ground. For example, displaying the word "Danger" can alert people in the vicinity and discourage them from entering the area.

[0015] The light application device preferably applies a flashing light beam.

[0016] According to this configuration, the light irradiation device irradiates a blinking light beam, which easily attracts the attention of people in the vicinity.

[0017] It is preferable that the vehicle has a cargo box, and the light irradiation device is provided on the cargo box.

[0018] According to this configuration, the vehicle has a cargo box, and by providing a light beam projection device on the cargo box, it is easy to project light beams onto the ground where the cargo receiving platform is deployed without being interfered with by the cargo receiving platform in the standby position.

[0019] It is preferable that the light irradiation devices are provided at a plurality of locations on the loading platform.

[0020] According to this configuration, since the light beam irradiation devices are provided at multiple locations on the loading platform, the light beam can be reliably irradiated onto the ground to which the loading platform is moved.

[0021] A second aspect of the present invention is a vehicle having a loading platform and a loading platform lifting device for raising and lowering the loading platform, which raises and lowers the loading platform to load and unload cargo onto the platform, wherein the loading platform takes an operating position in which it occupies the ground in a state of extending behind the platform when loading and unloading cargo, and takes a retracted position in which it does not occupy the ground behind the platform when not loading and unloading cargo, and has a light irradiation device that is capable of irradiating light onto the ground in the area occupied by the loading platform in the operating position.

[0022] The loading platform of the vehicle of this aspect assumes an operating position in which it occupies the ground with the platform protruding out to the rear when loading and unloading luggage, and assumes a retracted position in which it does not occupy the ground behind the platform when not loading and unloading luggage. That is, when the loading platform changes its position from the retracted position to the operating position, the loading platform moves into the space behind the platform. Therefore, when the loading platform is in the retracted position, the space behind the platform is empty, and people can pass through it or place objects there. However, if the loading platform is changed to the operating position in this state, there is a risk that the loading platform may come into contact with people or objects. According to this aspect, the vehicle has a light ray irradiation device that can irradiate light rays onto the ground in the area occupied by the receiving platform in the operating position at least when the receiving platform is in the retracted position, so that people at the rear of the vehicle can see the ground irradiated with the light rays and recognize in advance that the receiving platform is moving. This can alert people in the vicinity, and they can evacuate from the area before the receiving platform deploys to the operating position. In addition, a worker who loads and unloads luggage can check whether or not an object is present in the area irradiated with the light rays before the receiving platform assumes the operating position. If an object is present in the area irradiated with the light rays, the object will be present on the ground in the area occupied by the receiving platform in the operating position, and the object will be exposed to the light rays. Therefore, the worker can notice the presence of an object exposed to the light rays and remove (move) the object from the area occupied by the receiving platform in the operating position (area irradiated with the light rays). If an object on the ground in the area occupied by the loading platform in the operating position (area irradiated with the light beam) cannot be removed, the worker can take safety measures such as moving the vehicle and changing the location where the loading and unloading work is carried out. By irradiating light beams from the light irradiation device, the worker can make such a judgment and avoid the loading platform coming into contact with people or objects, which is extremely safe.

[0023] A third aspect of the present invention is a vehicle having a loading platform and a loading platform lifting device for raising and lowering the loading platform, which raises and lowers the loading platform to load and unload cargo onto the loading platform, wherein the loading platform lifting device has a parallel link mechanism connecting the loading platform and the loading platform, and the loading platform can be taken into an upright standby position and a horizontal operating position by the loading platform lifting device, and the vehicle has a light irradiation device that is capable of irradiating light onto the entire area occupied by the loading platform in the operating position on the ground.

[0024] The vehicle of this aspect has a loading platform and a loading platform lifting device for raising and lowering the loading platform, and is a vehicle in which the loading platform is raised and lowered by the loading platform lifting device, and cargo is loaded and unloaded from the loading platform. The loading platform lifting device has a parallel link mechanism that connects the loading platform and the loading platform, and the loading platform can be placed in an upright standby position and a horizontal operating position by the loading platform lifting device. Therefore, the loading platform in the standby position is in an upright position and occupies a very small area, while the loading platform in the operating position is in a horizontal position and occupies a large area, making it easy to place luggage on it. That is, when the loading platform changes (deploys) from the standby position to the operating position, it changes from an upright state to a horizontal state. In other words, the loading platform is disposed in the rear of the vehicle and occupies the area that was not occupied by the loading platform in the standby position in the operating position. Therefore, if people are passing through the area or objects are placed therein, there is a risk that the loading platform may come into contact with the people or objects. However, the vehicle of this aspect has a light beam irradiation device, and the light beam irradiation device can irradiate the entire area occupied by the cargo receiving platform in the operating position on the ground with light beams, so that a person at the rear of the vehicle can see the ground on which the light beams are irradiated and recognize in advance that the cargo receiving platform is moving. Therefore, people in the vicinity can be alerted and can evacuate from the vicinity of the area before the cargo receiving platform deploys to the operating position. Also, a worker who loads and unloads luggage can check whether or not there is an object in the area irradiated with the light beams before the cargo receiving platform deploys to the operating position in the horizontal state. If an object exists in the area irradiated with the light beams, the object is exposed to the light beams, so the worker realizes that the object must be removed, and can remove (move) the object (obstacle). If the object exposed to the light beams cannot be removed from the area occupied by the cargo receiving platform in the operating position (area irradiated with the light beams), the worker can take safety measures such as moving the vehicle and changing the location where the cargo receiving platform is loaded and unloaded. By emitting light from the light emitting device, the worker can make such a judgment and it is possible to prevent the loading platform from coming into contact with people or objects, which is extremely safe.

[0025] It is preferable that the parallel link mechanism is fixed to the loading platform at a predetermined height position, the parallel link mechanism rotates around the part fixed to the loading platform, and irradiates a light beam onto an area projected in a planar view onto the ground of the loading platform in an operating position at the height position of the rotation center of the parallel link mechanism.

[0026] According to this configuration, the parallel link mechanism is fixed to the loading platform at a predetermined height, and the parallel link mechanism rotates around the part fixed to the loading platform, irradiating a light beam onto an area projected in a planar view onto the ground of the loading platform in an operating position at the height position of the rotation center of the parallel link mechanism, so that the light beam is irradiated onto an area larger than the area occupied by the loading platform placed on the ground. As long as no person or object enters the area illuminated by the light beam, no person or object will come into contact with or collide with the lowering loading platform before it reaches the ground, ensuring safety.

[0027] A fourth aspect of the present invention is a vehicle loading platform lifting device that is mounted on a vehicle having a loading platform and raises and lowers a loading platform used for loading and unloading luggage from the loading platform of the vehicle, wherein the loading platform assumes an operating position in which it occupies the ground in a protruding state behind the loading platform when luggage is being loaded or unloaded, and assumes a retracted position in which it does not occupy the ground behind the loading platform when luggage is not being loaded or unloaded, and the vehicle loading platform lifting device is characterized in that it has a light irradiation device that emits a light beam indicating the area of ​​the ground occupied by the loading platform behind the vehicle.

[0028] The vehicle loading platform lifting device of this aspect is mounted on a vehicle having a loading platform, and lifts and lowers the loading platform used for loading and unloading luggage onto and from the loading platform of the vehicle. The loading platform takes an operating position in which it occupies the ground in a state of protruding behind the loading platform when loading and unloading luggage, and takes a retreated position in which it does not occupy the ground behind the loading platform when not loading and unloading luggage. That is, when the loading platform changes its position from the retracted position to the working position, the loading platform moves to the space behind the loading platform, so that when the loading platform is in the retracted position, the space behind the loading platform is open, allowing people to pass through and place objects there. However, if the loading platform is changed to an operating position in which it extends rearward in this state, there is a risk that the loading platform may come into contact with people or objects. According to this aspect, the vehicle has a light emitting device that emits a light beam indicating the area of ​​the ground occupied by the loading platform at the rear of the vehicle, and the light emitting device emits a light beam onto the area of ​​the ground occupied by the loading platform in the operating position, so that people at the rear of the vehicle can see the ground illuminated with the light beam and recognize in advance that the loading platform is moving. Therefore, before the loading platform deploys to the operating position, people in the vicinity are alerted and can evacuate from the area. Also, workers who load and unload luggage can check whether there is an object in the area illuminated with the light beam before the loading platform deploys to the horizontal operating position. If an object is present in the area illuminated by the light beam, the object (obstacle) will be exposed to the light beam, allowing the worker to notice the presence of the object and remove (move) it. If the object exposed to the light beam cannot be removed, the worker can take safety measures such as moving the vehicle and changing the location where the loading and unloading of cargo is carried out. By illuminating the light beam with the light beam illumination device, the worker can make such a judgment and avoid the situation where the loading platform comes into contact with people or objects, which is extremely safe.

[0029] The loading platform lifting device preferably has a parallel link mechanism that connects the loading platform and the loading platform, the parallel link mechanism being fixed to the loading platform at a predetermined height position, the parallel link mechanism rotating around a portion fixed to the loading platform and irradiating a light beam onto an area projected in a planar view onto the ground of the loading platform in an operating position at the height position of the rotation center of the parallel link mechanism. Effect of the Invention

[0030] The vehicle safety device, vehicle, and vehicle loading platform lifting device of the present invention can alert people around the vehicle when the loading platform is changed from a retracted position to an operating position, thereby preventing the loading platform from coming into contact with people or objects. [Brief description of the drawings]

[Figure 4]1A is a partial side view of the rear of a vehicle equipped with a safety device according to this embodiment, in which (a) shows the loading platform in an operating position positioned at the floor height of the cargo box, (b) shows the loading platform in (a) in the middle of descending, and (c) shows the loading platform in (b) having landed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The following description will be given with reference to the drawings. As shown in Figures 1(a), 1(b) and 2, a vehicle 1 carries a cargo box 2 on a vehicle body 1a (cargo platform). A bumper device 3 and a cargo platform lifting device 4 are attached to the rear of the vehicle body 1a. The cargo platform lifting device 4 has a parallel link mechanism 4a. The base side (front end side) of the cargo platform lifting device 4 is attached to the vehicle body 1a, and a cargo platform 7 on which cargo can be placed is attached to the tip side (rear end side), which is the free end.

[0033] The parallel link mechanism 4a is equipped with a drive cylinder 5, and the height position of the load-receiving platform 7 can be changed between the height of the ground G and the floor surface (not shown) of the cargo box 2 according to the extension and contraction of the drive cylinder 5. In addition, a drive cylinder (not shown) is provided at the portion of the parallel link mechanism 4a where the load-receiving platform 7 is connected. By driving this drive cylinder (not shown), the position of the load-receiving platform 7 can be switched between an upright position (retracted position) and a horizontal position (operating position).

[0034] Here, the operating position refers to a state in which the cargo receiving platform 7 is horizontal and disposed between the floor height of the cargo box 2 and the ground G. The retracted position refers to a state in which the cargo receiving platform 7 has moved from between the floor height of the cargo box 2 and the ground G. The platform lifting device 4 having the parallel link mechanism 4a is a conventionally known device, and other detailed description thereof will be omitted.

[0035] A light irradiation device 8 (safety device) is provided on the upper part (lintel) of the packing box 2. The light irradiation device 8 is composed of an LED lamp, and for example, an "LED drawing lamp" manufactured by Koito Manufacturing Co., Ltd. can be used.

[0036] As shown in Fig. 1(a) and Fig. 1(b), the light beam irradiation device 8 irradiates an irradiation light beam 9. The irradiation light beam 9 is irradiated to a predetermined range from the light beam irradiation device 8. As shown in Fig. 1(b), the range of the irradiation light beam 9 is the same as or slightly larger (wider) than the area occupied by the load receiving platform 7 in the operating position.

[0037] That is, the light beam irradiation device 8 can irradiate a light beam onto an area the same size as the area occupied by the cargo receiving platform 7 placed on the ground G, or onto an area slightly larger than the area occupied by the cargo receiving platform 7. In other words, as shown in Fig. 2, the irradiation light beam 9 irradiated from the light beam irradiation device 8 spreads into a light beam irradiation area 10 on the ground G, and the area of ​​this light beam irradiation area 10 is the same as or slightly larger than the area occupied on the ground G by the cargo receiving platform 7 in a horizontal position.

[0038] In this embodiment, as a preferred embodiment, an example is shown in which the light irradiation area 10 is the same as or slightly larger than the area occupied by the loading platform 7 on the ground G, but the light irradiation area 10 may also be smaller than the area occupied by the loading platform 7.

[0039] When the light beam irradiation area 10 coincides with the area that the receiving platform 7 occupies on the ground G, the outline of the light beam irradiation area 10 indicates the boundary between the area on the ground G that the receiving platform 7 occupies and other areas. That is, in this case, if outside the light beam irradiation area 10, there is no contact with the receiving platform 7 even if the receiving platform 7 in the standby position is changed to the operating position.

[0040] Additionally, "slightly" means within about plus or minus 30% of the area that the loading platform 7 occupies on the ground surface G. In practice, it is preferable for safety reasons to make the area that the loading platform 7 occupies on the ground surface G and the area irradiated by the irradiation light beam 9 slightly wider than to make the area that the irradiation light beam 9 irradiates coincident with each other or to make the area that the irradiation light beam 9 irradiates slightly narrower.

[0041] The light beam irradiation device 8 can irradiate a directional light beam, and can draw any character or shape on the ground G, for example, by drawing a character within a light beam irradiation range 10a as shown in Fig. 3(a), by irradiating a light beam in a frame shape on a light beam irradiation range 10b to draw a frame on the light beam irradiation range 10b as shown in Fig. 3(b), or by irradiating a light beam on the entire area of ​​a light beam irradiation range 10c as shown in Fig. 3(c). Also, in Figs. 3(a) to 3(c), the light beam irradiation device 8 can irradiate a blinking light beam, and the character or shape to be drawn on the ground G can be indicated by the blinking light beam.

[0042] In this embodiment, the light beam irradiation device 8 starts irradiating the light beam at the same time as the power supply to the receiving platform lifting device 4 is turned on. That is, the light beam irradiation device 8 starts irradiating the irradiation light beam before the receiving platform 7 in the retracted position changes position (deploys) to the horizontal operating position. Then, when the receiving platform 7 assumes the operating position, the light beam irradiation device 8 stops irradiating the irradiation light beam. In this manner, the timing of starting and stopping irradiation of the irradiation light beam 9 by the light beam irradiation device 8 is configured to be linked to the operation of the receiving platform lifting device 4. In response to an instruction to irradiate, it is possible to irradiate the irradiation light beam onto the ground (light beam irradiation area 10) in the area occupied by the receiving platform 7 in the operating position.

[0043] Here, the irradiation of the irradiation light beam 9 from the light irradiation device 8 may be started and stopped manually, independently of the operation of the loading platform lifting device 4, by providing a dedicated switch. Furthermore, the light irradiation device 8 may be configured to constantly irradiate the irradiation light beam 9.

[0044] In this embodiment, an example has been described in which the light irradiation device 8 irradiates the irradiation light beam 9 in accordance with the area (area) occupied by the receiving platform 7 on the ground G when it is placed on the ground G, but the irradiation light beam 9 can also be set to the maximum area range of the trajectory traced by the receiving platform 7 when it changes its position from the retracted position to the operating position (the widest area of ​​the receiving platform 7 projected onto the ground G when the receiving platform 7 is raised or lowered).

[0045] That is, as shown in Fig. 4(a) to Fig. 4(c), the load receiving platform 7 rotates around the connecting member 6 (a part fixed to the vehicle body 1a (loading platform) side) integral with the vehicle body 1a, and moves from the floor height of the cargo box 2 (Fig. 4(a)) to the ground G (Fig. 4(c)). At that time, when the load receiving platform 7 reaches the height position (predetermined height position) of the rotation center of the parallel link mechanism 4a (Fig. 4(b)), the end side 7a of the load receiving platform 7 protrudes most from the vehicle body 1a. That is, there is almost no difference in the front-rear direction positions (parts A and C projected onto the ground G) of the end side 7a of the load receiving platform 7 at the height positions shown in Fig. 4(a) and Fig. 4(c). However, as shown in Fig. 4(b), when the load receiving platform 7 reaches the height position of the rotation center of the parallel link mechanism 4a, the end side 7a protrudes backward beyond the position where part A is projected to the position where part B is projected.

[0046] Therefore, if a person or object approaches the vehicle body 1a from part B of the ground G, the loading platform 7 will come into contact with or collide with the person or object when it reaches the height position of the connecting member 6. Therefore, the irradiation range of the light irradiation device 8 is expanded to at least the portion B of the ground G (the movement trajectory of the load-receiving table 7, which is the maximum protruding range of the load-receiving table 7 toward the rear of the vehicle 1). That is, the irradiation light beam 9 is irradiated onto an area OB projected in a plan view onto the ground G of the load receiving platform 7 in an operating posture at the height position of the rotation center (connecting member 6) of the parallel link mechanism 4a. Here, part O is a portion near the rear of the vehicle body 1a, the front end of the projection area of ​​the load receiving platform 7, and indicates the position of the irradiation light beam irradiated by the light irradiation device 8 closest to the vehicle body 1a.

[0047] This makes it possible to prevent people or objects from entering the range of the movement trajectory of the loading platform 7 when it is raised or lowered, and to prevent contact or collision with the loading platform 7. In other words, it is preferable that the light irradiation device 8 irradiates the irradiation light beam 9 not only to the OA area in the front-rear direction of the vehicle 1, but also to the OB area.

[0048] The size relationship between area OA and area OC varies depending on the floor height of the load-receiving platform 7 and the height of the connecting member 6, but area OB is always larger than areas OA and OC. In other words, if the irradiation beam 9 is irradiated onto area OB and no person or object enters the range of area OB, the load-receiving platform 7 will not come into contact with or collide with anything as it rises and falls.

[0049] In this embodiment, the light beam irradiation device 8 is provided on the lintel part (upper part) of the packing box 2, but the light beam irradiation device 8 may be provided at a position other than the lintel part of the packing box 2. For example, the light beam irradiation device 8 may be provided on the threshold part (lower part) of the packing box 2, the bumper device 3, the license plate (not shown), or the vehicle body 1a (chassis frame).

[0050] In addition, although the present embodiment shows an example in which one light beam irradiation device 8 is provided, a plurality of light beam irradiation devices 8 may be provided. For example, the light beam irradiation devices 8 may be provided at several (a plurality of) locations among the lintel and threshold of the cargo box 2, the bumper device 3, the license plate (not shown), the vehicle body 1a (chassis frame), and the like.

[0051] The color of the irradiated light beam 9 is arbitrary and may be any color. When a plurality of light irradiation devices 8 are provided, the color of the irradiated light beam may be the same, or different colors may be used for each.

[0052] In this embodiment, the loading platform 7 is described as being raised and lowered by the parallel link mechanism 4a and switched between a horizontal position and an upright position, but the present invention can be implemented in the same way even if the loading platform 7 is a vertical lifting type or an underfloor storage type. The vertical lifting type is a type in which the loading platform 7 is raised and lowered along a support provided on the vehicle (car body 1a or cargo box 2). The loading platform 7 may be manually moved from a vertical position to a horizontal position (or vice versa). The underfloor storage type is a type in which the loading platform is stored (retracted) below the car body 1a (cargo platform) and protrudes rearward during operation. [Explanation of symbols]
