[0048] The cone setting and recovering device 1, 100 of the present application integrally has two functions of a cone setting device for placing a conical road regulating member (cone C) in an erected state on a road surface G of a road and a cone recovering device for recovering the conical road regulating member placed in the erected state on the road surface G of the road. Therefore, in the following description, the cone setting device and the cone recovering device are described by the cone setting and recovering device 1, 100. Further, in the case where the cone setting and recovering device 1, 100 is used as the cone setting device and the cone recovering device respectively, as described later, some elements need to be disassembled.

[0049] As the cone setting device, the cone setting and recovering device 1, 100 includes a setting portion for placing a conical road regulating member (hereinafter referred to as cone C) in an erected state on a road surface G of a road and a coupling portion 70, 170 for coupling the setting portion to the side outside of a cargo bed 6, 106 of a vehicle 4, 104. In addition, as the cone recovering device, the cone setting and recovering device 1, 100 includes a recovering portion for recovering the cone C and a coupling portion 70, 170 for coupling the recovering portion to the side outside of the cargo bed 6, 106 of the vehicle 4, 104. Here, as described later, most of the configuration of the setting portion and the recovering portion are common, and therefore, the setting and recovering portion 10, 110 is described in detail as the setting portion. In addition, the coupling portion 70, 170 is the same in the cone setting device and the cone recovering device. Further, as the vehicle 4, 104, a truck capable of carrying a plurality of cones C on the cargo bed 6, 106 and having the side of the cargo bed 6 open is generally assumed.

[0050] The setting and recovering portion 10, 110 as the setting portion is configured by a wheel 18, 118, a placing portion 20, a lowering device, and a pushing-out device 50, 150. The wheel 18, 118 is for running in contact with the road surface G of the road. The placing portion 20 places the cone C in the erected state, and as long as the cone C can be placed in the erected state, it does not necessarily need to be a plate shape. The lowering device lowers the placing portion 20 from the height of the cargo bed 6, 106 of the vehicle 4, 104 to the height not in contact with the road surface G, and specifically, is a lifting device 30, 130. The pushing-out device 50, 150 is for pushing out the cone C placed on the placing portion 20 from the placing portion 20.

[0051] As the basic usage of the cone setting and collecting device 1, 100 as a cone setting device, first, the placing portion 20 places the cone C in an erected state in the placing portion 20 in a state where the placing portion 20 is located at the height of the cargo bed 6, 106 of the vehicle 4, 104. Here, the height of the cargo bed 6, 106 refers to the height of the placing portion 20 which is suitable for an operator who is located at the cargo bed 6, 106 to pick up one cone C from the cargo bed 6, 106 and place the cone C in an erected state, in a state where a plurality of cones C are stacked on the cargo bed 6, 106 of the vehicle 4, 104.

[0052] Then, the placing portion 20 on which the cone C is placed is lowered from the height of the cargo bed 6, 106 of the vehicle 4, 104 to a height which does not contact the road surface G by the lifting device 30, 130 as a lowering device. The height which does not contact the road surface G is preferably as close as possible to the height of the road surface G, but is preferably a height which is the limit at which the placing portion 20 does not contact the road surface G due to the unevenness of the road surface G.

[0053] In a state where the placing portion 20 on which the cone C is placed is lowered from the height of the cargo bed 6, 106 of the vehicle 4, 104 to a height which does not contact the road surface G, the pushing-out device 50, 150 pushes out the cone C from the placing portion 20 in the direction of the road surface G of the road and places the cone C in an erected state on the road surface G of the road, whereby the cone C is placed (set) on the road surface G.

[0054] Next, the collecting portion of the cone setting and collecting device 1, 100 as a cone collecting device, i.e., the setting and collecting portion 10, 110 is composed of the wheel 18, 118, the dumping arm 60, 160, the collecting rod 28, 128, and the lifting device, etc. The wheel 18, 118 is as described above. The dumping arm 60, 160 is used to dump the cone C which is erected on the road surface G on the road surface G. The collecting rod 28, 128 is inserted into the inner surface side of the cone C which is dumped by the dumping arm 60, 160 and hooks the dumped cone C. The lifting device, specifically the lifting device 30, 130, is used to lift the collecting rod 28, 128.

[0055] As the basic use method of the cone setting and recovering device 1, 100 functioning as a cone setting device, first, the vehicle 4, 104 is caused to travel toward the cone C standing on the road surface G of the road, and the cone C standing on the road surface G of the road is caused to fall by the dumping arm 60, 160. Next, the cone C fallen by the dumping arm 60, 160 is caused to be hooked to the recovering rod 28, 128, and the recovering rod 28, 128 on which the fallen cone C is hooked is caused to be raised to the height of the cargo bed 6, 106 of the vehicle 4, 104 by the lifting device 30, 130 functioning as a raising device. Here, the height of the cargo bed 6, 106 refers to the height at which the fallen cone C is unloaded from the recovering rod 28, 128 by the operator standing on the cargo bed 6, 106 of the vehicle 4, 104 and is piled on the cargo bed 6, 106.

[0056] The connecting portion 70, 170 for connecting the setting and recovering portion 10, 110 to the lateral outside of the cargo bed 6, 106 of the vehicle 4, 104 includes a cargo bed side fixing portion 72, 172 which is stopped and fixed to the cargo bed 6, 106 of the vehicle 4, 104, a setting and recovering portion side fixing portion 90, 190 which is a setting portion side fixing portion on the vehicle 4, 104 side fixed to the setting and recovering portion 10, 110 and is a recovering portion side fixing portion, and a connecting arm 94, 194 which is erected between the cargo bed side fixing portion 72, 172 and the setting and recovering portion side fixing portion 90, 190 disposed in the above and below positional relationship.

[0057] In the connecting portion 70, 170, one end of the connecting arm 94, 194 is swingably fixed to the cargo bed side fixing portion 72, 172 by the rotation damper 84, 184. In addition, the other end of the connecting arm 94, 194 is swingably fixed to the setting and recovering portion side fixing portion 90, 190 by the rotation damper 92, 192. By such a structure, the cargo bed side fixing portion 72, 172 and the setting and recovering portion side fixing portion 90, 190 of the connecting portion 70, 170 are swingably connected by the connecting arm 94, 194. Further, according to the connecting portion 70, 170 configured as such, the structure is simple and inexpensive, and can be provided to a majority of trucks and the like, and it is not necessary to prepare a dedicated vehicle.

[0058] According to the cone setting and recovering device 1, 100 configured as such and functioning as a cone setting device and a cone recovering device, the basic action is simple and inexpensive compared to the conventional cone setting and recovering device.

[0059] Example 1

[0060] Next, the use of the cone setting and recovering device 1, 100 configured as such will be described. Figures 1-8The conical body setting and collecting device 1 as one example of a conical body setting device will be described in detail. As described above, the conical body setting and collecting device 1 is outlined, and first, the details of the connecting portion 70 that connects the setting and collecting portion 10 of the conical body setting and collecting device 1 to the loading platform 6 of the vehicle 4 will be described.

[0061] The connecting portion 70 is composed of a loading platform side fixing portion 72, a setting and collecting portion side fixing portion 90 as a setting portion side fixing portion, and a connecting arm 94, and connects the setting and collecting portion 10 as a setting portion to the outside of the side of the loading platform 6 of the vehicle 4. The loading platform side fixing portion 72 of the connecting portion 70 is a structure that can be locked and fixed to the loading platform side plate 8 of the loading platform 6 of the vehicle 4. Specifically, the loading platform side fixing portion 72 is composed of an upper side portion 74, a locking portion 76, a downward portion 78, an abutting portion 80, a support portion 82, and the like.

[0062] The upper side portion 74 is composed of an upper side portion parallel portion 74a that extends in the advancing direction of the vehicle 4, and an upper side portion right angle portion 74b of a bar that extends at right angles from the end portions of the upper side portion parallel portion 74a in the front and rear (hereinafter, the front and rear refer to the front and rear with respect to the advancing direction of the vehicle 4). The downward portion 78 of a bar is downward from the end portions of the upper side portion parallel portion 74a in the front and rear of the upper side portion 74. In addition, the locking portion 76 of a bar is downward from the side opposite the downward portion 78 of each upper side portion right angle portion 74b of the upper side portion 74. The abutting portion 80 of a disc is provided at the lower end side of the locking portion 76 in a manner opposite the downward portion 78. Further, the support portion 82 of a plate is erected in a state with the surface facing the horizontal direction at the lower ends of the two downward portions 78. The rotation damper 84 is provided in a manner with the axis perpendicular to the plate face (i.e., in the horizontal direction) at the front and rear sides of the support portion 82.

[0063] The setting and collecting portion side fixing portion 90 of a plate that extends in a state with the face facing the horizontal direction is disposed below the support portion 82 of the loading platform side fixing portion 72. The rotation damper 92 is provided in a manner with the axis perpendicular to the plate face (i.e., in the horizontal direction) at the front and rear sides of the setting and collecting portion side fixing portion 90.

[0064] A plate-shaped connecting arm 94 is mounted between the front side of the support portion 82 of the loading platform side fixing part 72 and the front side of the receiving section side fixing part 90, and between the rear side of the support portion 82 of the loading platform side fixing part 72 and the rear side of the receiving section side fixing part 90. One end of each connecting arm 94 is flexibly fixed (shaft-supported) to the loading platform side fixing part 72 via a rotation damper 84, and the other end is flexibly fixed (shaft-supported) to the receiving section side fixing part 90 via a rotation damper 92. With this structure, the loading platform side fixing part 72 and the receiving section side fixing part 90 of the connecting part 70 are flexibly connected by the connecting arms 94, allowing for vertical movement.

[0065] The mounting and recycling section side fixing part 90 of the connecting part 70 is fixed to the side surface of the vehicle 4 side of the frame part 12 of the mounting and recycling section 10, which will be described later. The mounting and recycling section side fixing part 90 of the connecting part 70 is fixed at the height of the mounting and recycling section 10, which is the height at which the mounting and recycling section 10 can follow the unevenness of the road surface G and travel on the road surface G when the vehicle 4 and the mounting and recycling section 10 are connected by the connecting part 70.

[0066] like Figure 4 and Figure 12 As shown, the loading platform side fixing part 72 of the connecting part 70 is fixed to the loading platform side plate 8 of the loading platform 6 of the vehicle 4. Specifically, the loading platform side fixing part 72 is inserted into the loading platform side plate 8 between the inverted U-shaped locking part 76 (abutting part 80) and the downward part 78, and is placed such that the lower surface of the upper right angle part 74b of the upper part 74 abuts against the upper end of the loading platform side plate 8. Then, the abutting part 80 is pressed from the locking part 76 onto the loading platform side plate 8, thereby locking and fixing the loading platform side fixing part 72 to the loading platform 6 (loading platform side plate 8).

[0067] Next, a specific example of the setting and retraction unit 10, which serves as the setting part of the cone setting device, will be described. The setting and retraction unit 10 consists of a frame 12, wheels 18, a mounting part 20, a lifting device 30 as a lowering device, and a pushing device 50. The frame 12 is a longitudinally elongated, approximately rectangular frame, consisting of four sides of the vehicle and two opposite sides. Support rods 14 and 16 are respectively mounted on the top and bottom sides of the two frame parts 12, and the two frame parts 12 are spaced apart to accommodate the cone C. Four wheels 18 are provided on the outer side of the bottom side of the frame part 12.

[0068] A vertically extending lifting device 30 is provided between support rods 14 and 16. For example... Figure 4As shown, the lifting device 30 is in a tower shape, and stands up in the center of the two frame portions 12. In addition, on both sides of the tower-shaped lifting device 30 (each frame portion 12 side), a guide rod 40 extending upward and downward is erected between the strut 14 and the strut 16 (the upper end of the guide rod 40 is fixed to the strut 14 by a guide rod fixing member 40a).

[0069] The lifting device 30 is constituted by a chain 34 strung on pulleys 34a (not shown on the lower side) provided on the inside of the upper side and the lower side, a motor 32 that rotates the pulley on the lower side, and a cover plate 38 that covers these, and the like.

[0070] As shown in Figures 2-4 , the placement portion 20 is disposed between the two frame portions 12, and as shown in Figure 2 , is in a substantially L shape when viewed from the front, and the bottom surface is in a hopper shape that enables the cone C to be placed in a standing state on the placement plate 22. The standing plate 24 is located on the back side of the placement portion 20, and the standing plate 24 is connected to the chain 34 of the lifting device 30 by a connecting portion 36. In addition, the standing plate 24 of the placement portion 20 is fixed to a guide portion 42 that is slidably held by the two guide rods 40. The placement portion 20 of such a configuration is able to be raised or lowered by the movement of the chain 34 of the lifting device 30 in a state of being slidably held by the guide rods 40. By such a configuration, the placement portion 20 becomes in a state of being open toward the outside of the setting and recovering portion 10 (toward the axis of the advance or retreat of the vehicle 4).

[0071] A push-out device 50 is provided on the bottom side of the strut 16 between the two frame portions 12 of the setting and recovering portion 10. A solenoid 54 of the push-out device 50 is disposed in the axis of the advance or retreat of the vehicle 4, and a push-out plate 52 is provided perpendicularly at the end of the solenoid 54. The push-out plate 52 is normally erected at the same position as the standing plate 24 of the placement portion 20, and is pushed out to a placement plate groove 22a provided in the placement plate 22 by the movement of the solenoid 54 at the time of pushing out the cone C, which will be described later.

[0072] Next, the action and the use method of the cone setting and recovering device 1 as a cone setting device will be described using Figures 5-8 . Figures 5-8 The description of the vehicle 4 and the connecting portion 70 is omitted in the following.

[0073] First, as shown in Figure 5 (a) and Figure 5 (b), the cone C is placed in a standing state on the placement plate 22 of the placement portion 20 in a state where the placement portion 20 is at the height of the cargo bed 6 of the vehicle 4. Then, as shown by the arrow in Figure 5 (a) and Figure 6 (a) and Figure 6(b) shown, the placement portion 20 (placement plate 22) on which the cone C is placed is lowered from the height of the cargo bed 6 of the vehicle 4 to a height not in contact with the road surface G by the lifting device 30 as a lowering device.

[0074] The timing at which the placement portion 20 (placement plate 22) on which the cone C is placed is lowered from the height of the cargo bed 6 can be directly operated by the worker, and in addition thereto, can be set to be automatically lowered. For example, a lowering control device (not shown) can be provided, and when it is detected that the cone C is placed on the placement portion 20 at the height of the cargo bed 6 of the vehicle 4, the lowering of the placement portion 20 by the lifting device 30 is started. If this lowering control device is provided, the worker can place the cone C on the placement portion 20 (placement plate 22), and the work becomes easy.

[0075] Next, in the state in which the placement portion 20 on which the cone C is placed is lowered from the height of the cargo bed 6 of the vehicle 4 to a height not in contact with the road surface G as shown in Figure 6 (a) and Figure 6 (b), the cone C is pushed out from the placement portion 20 (placement plate 22) toward the road surface G by the pushing-out device 50. Specifically, the solenoid 54 of the pushing-out device 50 causes the pushing-out plate 52 to protrude, and the pushing-out plate 52 pushes out the cone C on the placement plate 22 from the placement portion 20 (placement plate 22) toward the road surface G as shown in Figure 7 . Thus, as shown in Figure 8 , the cone C pushed out from the placement portion 20 (placement plate 22) by the pushing-out device 50 becomes a state of falling on the road surface G, and in addition, since the placement portion 20 is pushed out from the height of the cargo bed 6 of the vehicle 4 to a height not in contact with the road surface G, the cone C is placed on the road surface G in a standing state. At this time, by causing the vehicle 4 to travel in the opposite direction to the direction in which the cone C is pushed out (the recovery portion 10 is also caused to travel in the opposite direction to the direction in which the cone C is pushed out), the cone C becomes a state of being disposed and remaining on the road surface G.

[0076] In addition, the timing at which the pushing-out device 50 pushes out the cone C from the placement portion 20 (placement plate 22) toward the road surface G can also be controlled by a device that is automatically controlled in accordance with the traveling state of the vehicle 4 (recovery portion 10) or the like. However, it is not limited to being automatically controlled, and the timing at which the cone C is pushed out can also be determined by the worker. Specifically, a pushing-out instruction switch (not shown) for instructing the timing at which the cone C is pushed out toward the road surface G to the pushing-out device 50 can also be included. If automation is performed, a complicated and expensive structure is required, but if the pushing-out instruction switch is used, the timing at which the cone C is pushed out can be obtained by a simple and inexpensive method.

[0077] After the ejection of the cone C (the placement of the cone C to the road surface G) is completed, the ejection plate 52 returns to the original position, and the empty placement portion 20 is returned to the height of the loading platform 6 by the lifting device 30. Then, as described above, the operator places the cone C again on the placement portion 20 (the placement plate 22), and the setting of the cones to the road surface G is repeated. During this period, the vehicle 4 is driven (the setting recovery portion 10 is also driven) in the direction opposite to the direction in which the cone C is ejected (in the case of the vehicle 4 in Figure 1

[0078] Example 2

[0079] Next, the cone setting and recovery device 1 as one example of the cone recovery device will be described in detail using Figures 9-16 The outline of the cone setting and recovery device 1 is as described above, and, regarding the same reference numerals as those on the drawing described in Example 1, the description will be omitted. The difference between Example 1 and Example 2 is that the cone setting and recovery device 1 as the cone setting device has the placement portion 20, and instead, the cone setting and recovery device 1 as the cone recovery device has the dumping arm 60 and the recovery rod 28 (including the standing plate 26). Further, with respect to the cone setting and recovery device 1, the placement portion 20, the dumping arm 60, and the recovery rod 28 (including the standing plate 26) are replaced depending on whether the cone setting and recovery device 1 is used as the cone setting device or as the cone recovery device.

[0080] The dumping arm 60 of the cone setting and recovery device 1 as the cone recovery device is used to dump the cone C standing on the road surface G on the road surface G, and is disposed on the side closest to the cone C standing on the road surface G to be recovered in the traveling direction of the cone setting and recovery device 1. Specifically, in the example of the dumping arm 60 of Example 2, as shown in Figure 11

[0081] Figures 10-12 ​​​As shown, the recovery rod 28 is positioned between the two frame sections 12, protruding horizontally from the lifting device 30 (which serves as a lifting device) towards the cone C to be recovered, which is erected on the road surface G in the direction of travel where the recovery device 1 is installed on the cone. One end of the recovery rod 28 (the fixed side, the lifting device 30 side) is fixed to the erecting plate 26, which is connected to the chain 34 of the lifting device 30 via a connecting part 36. The other end of the recovery rod 28 is open.

[0082] The lifting plate 26 is fixed to the guide portion 42, which is slidably held in place by the two guide rods 40. The retraction rod 28 (lifting plate 26) can be raised or lowered by moving the chain 34 of the lifting device 30 while it is slidably held in place by the guide rods 40.

[0083] Next, use Figures 13-16 This section explains the operation and usage of the cone-setting recovery device 1, which is a cone recovery device. Figures 13-16 The description of vehicle 4 and connecting part 70 is omitted.

[0084] First, the vehicle 4, i.e., the recycling unit 10, is driven towards the cone C erected on the road surface G. Then, as... Figure 13 As shown, the V-shaped portion 60aa of the M-shaped portion 60a of the tilting arm 60 abuts against the upper part of the cone C erected on the road surface G. At this time, even if the upper part of the cone C is not located in the center of the V-shaped portion 60aa of the M-shaped portion 60a of the tilting arm 60, the upper part of the cone C will shift towards the center of the V-shaped portion 60aa due to the V-shape, forming... Figure 13 (b) shows the positional relationship. Furthermore, the shape of the tilting arm 60 does not need to be M-shaped as long as the cone C is tilted and locked in place by the recovery rod 28, but by being M-shaped, the recovery of the cone C can be performed more reliably.

[0085] Furthermore, if vehicle 4 moves the recycling device 10, then as Figure 14 As shown, the tilting arm 60 begins to tilt the cone C, and the cone C tilts. If the recovery device 10 is provided and moves toward the tilted cone C, then as... Figure 15 As shown, the recovery rod 28 is inserted into the inner surface of the tilted cone C. Thus, the tilted cone C is engaged with the recovery rod 28.

[0086] Next, the recovery rod 28, with the tilting cone C attached, is raised to the height of the loading platform 6 of the vehicle 4 via the lifting device 30, which serves as a lifting mechanism. Figure 16 As shown, with the cone C raised to the height of the loading platform 6 of the vehicle 4 via the recovery rod 28, the operator removes the cone C from the recovery rod 28 and recovers the cone C. The recovered cone C is then transferred to the loading platform 6 of the vehicle 4.

[0087] Moreover, the timing at which the recovery lever 28 in the state of being caught with the cone C is raised from the position of the road surface G can also be controlled using a device that automatically controls so that the recovery lever 28 is automatically started to be raised when it is detected that the recovery lever 28 is caught with the cone C. However, the timing at which the recovery lever 28 is raised can also be decided by the operator, not limited to the case of automatically controlling. Specifically, a raising start instruction switch (not shown) for instructing the lifting device 30 of the timing at which the recovery lever 28 is raised can also be included. Although automation requires a complex and expensive structure, if it is a raising start instruction switch, the timing at which the recovery lever 28 is raised can be obtained by a simple and inexpensive method. A use method in which the recovery lever 28 is raised in the state of being caught with two cones C by the raising start instruction switch can also be adopted.

[0088] Moreover, the cone setting and recovery device 1 can also be installed on either side of the outer side of the cargo bed 6 of the vehicle 4, and can be arbitrarily decided according to which side is used or which position it is desired to set the cone C with respect to the road, and the like. According to which side of the outer side of the cargo bed 6 of the vehicle 4 the cone setting and recovery device 1 is installed, the direction of the setting and recovery portion 10 can also be arbitrarily decided according to the setting direction of the cone C, the recovery direction, and the like.

[0089] Example 3

[0090] Next, the cone setting and recovery device 100, which has the same basic structure as the cone setting and recovery device 1, but is partially modified, will be described using Figure 17 and Figure 18 However, since the description of the cone setting and recovery device 100 as a cone recovery device is more different than the cone setting and recovery device 1, the description will be mainly as a cone recovery device. Moreover, the operation of the cone setting and recovery device 100 is the same as that of the cone setting and recovery device 1.

[0091] First, the skeleton portion 112 of the setting and recovery portion 110 of the cone setting and recovery device 100 is the same shape as the skeleton portion 12 of the cone setting and recovery device 1, and the struts 114 and 116 connecting the left and right skeleton portions 112 are the same as the struts 14 and 16 of the cone setting and recovery device 1. However, the wheels 118 are set to be larger in diameter than the wheels 18 of the cone setting and recovery device 1, and greatly protrude to the side of the skeleton portion 112. In this way, by setting the wheels 118 that are larger in diameter to greatly protrude to the side of the skeleton portion 112, the setting and recovery portion 110 of the cone setting and recovery device 100 can stably travel on the road surface G of the road. In addition, as Figure 17As shown, the position of the cargo bed 106 of the vehicle 104 on which the cone setting and recovering device 100 is provided is located on the front side of the rear wheel 104b, rather than being located midway between the front wheel 104a and the rear wheel 104b as in the example of the cone setting and recovering device 1. By providing the cone setting and recovering device 100 on the cargo bed 106 on the front side of the rear wheel 104b, the cone setting and recovering device 100 also more stably follows the vehicle 104 in the case where the vehicle 104 is curved and the setting or recovering of the cone C is performed.

[0092] Further, the standing plate 126, the recovering rod 128, the lifting device 130, the electric motor 132, the connecting portion 136, the cover plate 138, the guide rod 140, the guide rod fixing member 140a, and the guide portion 142 are the same structures as those of the cone setting and recovering device 1.

[0093] Regarding the ejecting device 150, the cone setting and recovering device 1 uses the solenoid 54 to move the ejecting plate 52, but in the cone setting and recovering device 100, the electric motor 154 is used as a driving source, and a driving portion 156 having a chain structure is used to move the ejecting plate 152. Thus, the cone setting and recovering device 100 is able to act only by electric power.

[0094] The basic shape of the dumping arm 160 is the same as that of the cone setting and recovering device 1, and is a shape in which a round bar is bent in an approximately M shape upward in plan view, and a linear portion 162 is detachably fixed from each of the frame portions 112 from the end portions of the approximately M shape. The shapes of the M-shaped portion 160a and the V-shaped portion 160aa of the dumping arm 160 are also the same as those of the dumping arm 60 of the cone setting and recovering device 1, but in the dumping arm 160, a protruding guide portion 160b protruding in an approximately U shape is provided on the outer sides of the linear portion 162 on the traveling direction side of the dumping arm 160. Including the protruding guide portion 160b, the dumping arm 160 is a shape that enables the cone C to be reliably dumped in front of the recovering rod 128.

[0095] The structure of the connecting portion 170 is slightly different from that of the connecting portion 70 of the cone setting and recovering device 1. Specifically, a height adjustment portion 174 that adjusts the height from the cargo bed side plate 108 is provided on the upper portion of the cargo bed side fixing portion 172. Then, the following basic structure is the same as that of the connecting portion 70 of the cone setting and recovering device 1, and the connecting arm 194 is swingably provided between the cargo bed side fixing portion 172 and the setting and recovering portion side fixing portion 190 by the rotation dampers 184, 192. However, in the cone setting and recovering device 100, the connecting arm 194 is provided in a manner that hangs in a plumb shape, unlike the connecting arm 94 of the cone setting and recovering device 1. Figure 17 As can be seen, the connecting arm 194 is different from the connecting arm 94 of the cone setting and recovering device 1, and is provided in a manner that hangs in a plumb shape.

[0096] The present application can have various embodiments and modifications without departing from the broad spirit and scope of the present application. In addition, the above-described embodiments are for describing the present application and do not limit the scope of the present application. That is, the scope of the present application is indicated by the claims rather than the embodiments. And, various modifications implemented within the meaning of the claims and the equivalent of the present application are to be considered within the scope of the present application.

[0097] This application is based on Japanese Patent Application No. 2023-086676 filed on May 26, 2023. The disclosure of Japanese Patent Application No. 2023-086676 is incorporated herein by reference in its entirety.
