[0008] The equipment loading device according to a first embodiment of the present invention is a device that is installed at the rear of a vehicle having a chassis frame arranged in the fore-and-aft direction of the vehicle, and that loads equipment so that it can be pulled out of the vehicle, and that includes: a loading platform on which the equipment is placed and which can be moved between a loading position on the vehicle and a pulled-out position outside the vehicle which is lower than the loading position; a holding member that holds the loading platform between the chassis frames; a rail member that is installed on a subframe arranged on the chassis frame at an angle to the horizontal so that the rear side of the vehicle is lower; a sliding member to which the loading platform is attached and which slides along the rail member; a winch having a wire rope wound around a drum; a rope fastening member that is connected to the sliding member and to which the wire rope is fastened; and a locking member that locks the sliding of the sliding member. When installed in a vehicle, the loading surface of the loading platform in the loading position is lower than the floor of the vehicle's loading platform, When the mounting table is in the loading position, if the wire rope connected to the rope fastening material is unwound from the drum with the locking material unlocked, the slide material slides diagonally downward, causing the mounting table to move to the extraction position, and when the mounting table is in the extraction position, if the wire rope connected to the rope fastening material is wound onto the drum, the slide material slides diagonally upward, causing the mounting table to move to the loading position. In addition, since the loading height of the equipment is lower than when it is placed on the floor, operability when operating the equipment while it is placed on the platform and visibility of instruments are improved. According to this embodiment, by moving the mounting platform using an inclined rail member and a slide member that slides along the rail member, when raising or lowering the portable pump, it is possible to move it from the mounting position to the extended position, or from the extended position to the mounting position, in a single operation. Furthermore, by using a winch, the burden on firefighters and others can be reduced compared to manually raising and lowering the mounting platform, and the mounting platform can be raised and lowered safely and quickly.

[0009] The present invention No. 2 In this embodiment, in the equipment loading device according to the first embodiment, a hook is provided at the tip of the winch, which is detachably connected to a rope fastening material. According to this embodiment, the winch can be used not only to raise and lower the table but also for other tasks such as removing obstacles.

[0010] The present invention The third The embodiment of the present invention is No. 2 The equipment loading device according to the embodiment is provided with a detection means for detecting whether or not a hook is hooked on the rope fastening material, and a notification means for notifying the result of detection by the detection means. According to this embodiment, it is possible to prevent firefighters or the like from unlocking the locking member when the hook is not engaged.

[0011] The present invention Fourth The embodiment of the present invention is No. 1 In the equipment loading device according to the embodiment, the rope fastening member is located on the tip side of the loading platform. According to this embodiment, the hook can be easily attached to and detached from the rope anchoring material.

[0012] The present invention No. 5 The embodiment of the present invention is No. 1 In the equipment loading device according to the embodiment, the loading table is attached to the slide member with the loading surface being horizontal. According to this embodiment, the equipment placed on the table is also horizontal, making it easier to operate the equipment while it is placed on the table.

[0013] The present invention No. 6 In this embodiment, in the equipment loading device according to the first embodiment, the inclination angle of the rail material is set to 5 degrees or more and 15 degrees or less. According to this embodiment, the slide member can be smoothly slid with the equipment placed on the platform without requiring a particularly large winch capacity. Also, in the unlikely event of a winch malfunction, the platform with the equipment placed on it can be manually pushed up from the extracted position to the loaded position with a relatively small force, and can be safely extracted from the loaded position to the extracted position.

[0014] The present invention SeventhThe vehicle according to the embodiment includes first to No. 6 The equipment loading device is provided according to any one of the above embodiments. According to this embodiment, the loading height of the equipment is lower than when it is placed on the floor, so a vehicle can be provided that is easy to operate when the equipment is placed on the loading platform and has excellent visibility of the instruments. [Example]

[0015] Hereinafter, an equipment loading device according to an embodiment of the present invention and a vehicle equipped with the equipment loading device will be described. FIG. 1 is a schematic side view of a vehicle equipped with an equipment loading device according to this embodiment. Note that FIG. 1 also shows some of the components arranged inside the vehicle to make the configuration easier to understand. FIGS. 2 to 4 are schematic diagrams of the rear of a vehicle equipped with an equipment loading device, with (a) being a perspective view, (b) being a side view, (c) being a rear view, and (d) being a top view. FIG. 2 shows the loading platform in the loading position, FIG. 3 shows the loading platform in the extended position, and FIG. 4 shows the state in which an obstacle is being towed by the winch's wire rope. Note that in FIGS. 2 to 4, exterior panels and the like are omitted to make the configuration easier to understand. The vehicle 1 is provided with a chassis frame 5 having a left chassis frame 5A and a right chassis frame 5B extending in the longitudinal direction of the vehicle. The vehicle 1 in this embodiment is a fire engine, and an equipment loading device is provided at the rear of a loading platform (luggage compartment) 3 installed behind the cabin 2, using a subframe 6 installed on the chassis frame 5 of the vehicle 1, so that equipment (portable pump) 4 placed on the equipment loading device can be pulled out towards the rear of the vehicle. The pulled-out portable pump 4 can be removed from the equipment loading device and transported to the fire scene, etc. Note that the portable pump 4 is not shown in Figures 2 to 4.

[0016] The equipment loading device is a device for loading a portable pump 4 so that it can be pulled out of the vehicle, and is equipped with a mounting platform 10 on which the portable pump 4 is placed, a pair of rail members 20 installed on a subframe 6, a pair of slide members 30 to which the mounting platform 10 is fixed and which slide along the rail members 20, an electric winch 40 installed on the subframe 6 and having a wire rope 41 wound around a drum, a rope fastening member 50 to which a hook 42 attached to the end of the wire rope 41 is connected, a locking member 60 that locks the slide member 30 to prevent it from sliding, and a holding member 70 that holds the mounting platform 10 in a state where it is spanned between the chassis frames 5. The platform 10 is movable between a loading position on the vehicle and a pulled-out position outside the vehicle that is lower than the loading position, and is located between the left chassis frame 5A and the right chassis frame 5B in a top view. The left chassis frame 5A is located to the left of the center in the vehicle width direction, and the right chassis frame 5B is located to the right of the center in the vehicle width direction. The rail material 20 consists of one rail material 20A located above the left chassis frame 5A and the other rail material 20B located above the right chassis frame 5B, and is installed diagonally relative to the approximately horizontal subframe 6 to which it is attached so that the rear side of the vehicle is lower. The slide member 30 is made up of one slide member 30A fitted to one rail member 20A, and the other slide member 30B fitted to the other rail member 20B. The slide member 30 has a multi-stage telescopic structure, and its length increases as it protrudes from the rail member 20. When the slide member 30 is in its most retracted state, it does not protrude further rearward than the rear face of the vehicle 1.

[0017] As the holding member 70, mounting brackets 71 are provided on the leading stages of one slide member 30A and the other slide member 30B, and a plurality of fixing members 72 are provided on both the left and right ends of the mounting base 10. The mounting brackets 71 protrude downward more gradually as they approach the front of the vehicle. By connecting the fixing member 72 to the lower part of the mounting bracket 71, the mounting base 10 is attached to the sliding member 30 so as to bridge between the left chassis frame 5A side and the right chassis frame 5B side. This also results in one sliding member 30A and the other sliding member 30B being connected via the mounting base 10. By arranging the mounting platform 10 between the chassis frames 5 rather than on the floor of the loading platform 3, the mounting surface of the mounting platform 10 in the loading position can be made lower than the floor of the loading platform 3 of the vehicle 1. This makes the loading height of the portable pump 4 (the height from the ground when the mounting platform 10 is in the loading position) lower than in the case of a conventional floor-mounted arrangement, improving operability when operating the portable pump 4 while it is placed on the mounting platform 10 and visibility of instruments. Note that the height of the mounting surface of the mounting platform 10 in the loading position is preferably approximately the same as or lower than the top end of the chassis frame 5.

[0018] The mounting base 10 is preferably attached to the slide member 30 so that the mounting surface is approximately horizontal (approximately parallel to the chassis frame 5). This makes the portable pump 4 mounted on the mounting base 10 also approximately horizontal, making it easier to operate the portable pump 4 while it is mounted on the mounting base 10 and also making it easier to see the instruments provided on the portable pump 4. The area below the mounting table 10 is open and has no floor, making it possible to drain or exhaust the air while the portable pump 4 is still loaded. Furthermore, if the drain pipes and exhaust pipes connected to the portable pump 4 at one end are open to the atmosphere and the other ends are not connected to anything, it is not necessary to remove these pipes when lowering the portable pump 4, and the portable pump 4 can be lowered quickly.

[0019] The winch 40 is mounted on a platform 43 attached to the subframe 6 below the rail material 20 so as to span between the left chassis frame 5A and the right chassis frame 5B. The platform 43 protrudes downward from the lower end of the chassis frame 5, and the rear cover 7 is hingedly connected to the rear of the vehicle. By positioning the winch 40 in this manner, the operator of the winch 40 can easily visually check the winding status of the wire rope 41. Furthermore, since there is no need to provide installation space for the winch 40 on the loading platform 3, it becomes possible to load other firefighting equipment onto the loading platform 3. The winch 40 is operated by a person using a wired or wireless controller or the like. A rope anchoring member 50 is provided on the front end side (rear side of the vehicle) of the platform 10. The rope anchoring member 50 has a ring on which a hook 42 at the front end of a wire rope 41 can be hung, and the wire rope 41 is connected to the rope anchoring member 50 by hanging the hook 42 on this ring. The hook 42 is detachable from the rope anchoring member 50, and can be used for other tasks in addition to using the winch 40 to raise and lower the platform 10, such as by removing an obstacle α, such as a fallen tree, as shown in FIG. 4 . The rope anchoring member 50 can also be provided on the rear end side of the platform 10, but by providing it on the front end side of the platform 10, the hook 42 can be easily attached to and detached from the rope anchoring member 50.

[0020] The locking member 60 is provided on the subframe 6 so as to be located near the tip of the sliding member 30 when it is in its most retracted state. In addition, a fixing bar 61 is provided at the tip of the sliding member 30, protruding outward. The locking member 60 has a recess for receiving the fixing bar 61, and when the fixing bar 61 is locked in this recess, the sliding member 30 cannot slide. This prevents the mounting table 10 from unintentionally moving from the loading position to the drawn-out position.

[0021] Since the mounting platform 10 is attached to the sliding member 30, the rope anchoring member 50 provided on the mounting platform 10 is indirectly connected to the sliding member 30. Therefore, by hooking the hook 42 of the wire rope 41 onto the rope anchoring member 50 and operating the winch 40, the sliding direction and speed of the sliding member 30 can be controlled. It is also possible to connect the rope anchoring member 50 directly to the sliding member 30. When the wire rope 41 with the hook 42 hooked on the rope fastening material 50 is unwound from the drum with the locking material 60 unlocked, the loading table 10 at the loading position moves to the drawing-out position as the sliding material 30 slides obliquely downward. Furthermore, when the wire rope 41 with the hook 42 attached to the rope fastening member 50 is wound onto the drum, the platform 10 in the withdrawn position moves to the loading position as the sliding member 30 slides obliquely upward. After the platform 10 has been moved to the loading position, the sliding member 30 is locked with the locking member 60. In this way, by providing the rail members 20 at an angle and moving the mounting platform 10 by the slide members 30 that slide along the rail members 20, when raising or lowering the portable pump 4, it is possible to complete the movement from the mounting position to the drawn-out position, or the movement from the drawn-out position to the mounting position, in a single operation. Furthermore, by using the winch 40, the burden on firefighters and the like can be reduced compared to manually raising and lowering the mounting platform 10, and the mounting platform 10 can be raised and lowered safely and quickly. When moving the mounting base, the rear cover 7 on which the license plate and other parts are arranged is rotated downward and opened so as not to interfere with the slide member 30.

[0022] The inclination angle of the rail material 20 is preferably between 5 and 15 degrees, and more preferably about 10 degrees. By using such an inclination angle, the slide material 30 can slide smoothly with the portable pump 4 mounted on the mounting base 10 without requiring the winch 40 to have a particularly large capacity. Furthermore, in the unlikely event that a malfunction occurs in the winch 40, the mounting base 10 with the portable pump 4 mounted thereon can be manually pushed up from the extracted position to the loaded position with a relatively small force, and can also be safely extracted from the loaded position to the extracted position. When manually raising or lowering the winch 40, the clutch of the winch 40 is placed in neutral. Furthermore, as will be described later, if the locking material 60 is unlocked when the hook 42 is not hooked onto the rope anchoring material 50, or if the locking material 60 is unlocked when the wire rope 41 is slack, the sliding material 30 will suddenly slide and the portable pump 4 will slide out, but the speed can be reduced compared to when the slope is steep.

[0023] Figure 5 is an image diagram showing a safety device related to the connection of the hook, where Figure 5(a) is a bottom perspective view when the platform is in the pulled-out position, and Figure 5(b) is a top perspective view when the platform is in the loaded position. As described above, the hook 42 of the wire rope 41 can be detached from the rope anchoring member 50, and the winch 40 can be used not only to raise and lower the platform 10 but also for other tasks such as removing the obstacle α. However, although the hook 42 of the wire rope 41 can be detached even when the platform 10 carrying the portable pump 4 is in the loading position, if the locking member 60 is unlocked when the hook 42 is not engaged with the rope anchoring member 50, the platform 10 carrying the portable pump 4 will suddenly slide off. Therefore, as a safety device to prevent firefighters or the like from unlocking the locking member 60 when the hook 42 is not engaged, it is preferable to provide a detection means 80 that detects whether the hook 42 is engaged with the rope anchoring member 50 and an alarm means 81 that alarms the detection result of the detection means 80. In this embodiment, the detection means 80 is a U-shaped photoelectric sensor installed near the rope anchoring member 50, and the notification means 81 is an indicator installed near the locking member 60. The photoelectric sensor detects whether the hook 42 is connected to the rope anchoring member 50, and if the hook is connected, a green light on the indicator lights up, and if the hook is not connected, a red light on the indicator lights up. This allows firefighters or others attempting to unlock the locking member 60 to easily determine whether the hook 42 is connected to the rope anchoring member 50, thereby preventing them from accidentally unlocking the locking member 60 when the hook 42 is not connected. The notification means 81 may be one that notifies the user of the presence or absence of a hook connection using text, voice, or sound. Furthermore, when winding up the wire rope 41 after using the winch 40 to remove an obstacle, etc., there is a possibility that the wire rope 41 may become slackened due to the lack of load. If the locking member 60 is released to move the platform 10 to the withdrawn position while the wire rope 41 is in such a slack state, the platform 10 carrying the portable pump 4 will suddenly slide down to a position where the wire rope 41 can be taken up. For this reason, it is preferable to provide the equipment loading device with a slackness prevention device that prevents the wire rope 41 from becoming slackened.

[0024] FIG. 6 is an image diagram showing a method for fixing a portable pump to a mounting table, where FIG. 6(a) is a top perspective view showing the state before fixing, and FIG. 6(b) is a top perspective view showing the state after fixing. The equipment loading device includes, as members for fixing the portable pump 4 to the mounting base 10, nut plates 90 provided at each of the left and right ends of the mounting base 10, a fixing plate 91 that holds down the lower part of the portable pump 4 placed on the mounting base 10 from above, and butterfly bolts 92 that connect the nut plates 90 and the fixing plate 91. The nut plates 90 and the fixing plate 91 have holes formed therein through which the butterfly bolts 92 are passed, and the portable pump 4 is fixed to the mounting base 10 by placing the portable pump 4 on the mounting base 10, engaging the fixing plate 91 with the nut plate 90 so that the holes in the fixing plate 91 overlap the holes in the nut plate 90, and then fastening them together with the butterfly bolts 92. By fixing the portable pump 4 to the mounting base 10, the portable pump 4 can be prevented from slipping off the mounting base 10 while the vehicle is moving, and the portable pump 4 can be prevented from falling even if the mounting base 10 suddenly slides down due to slack in the wire rope 41 or the like.
