[0022] A traffic cone setup device / traffic cone collection device 1, 100 according to the present application has two integral functions: as a traffic cone setup device for setting up a cone-shaped road barrier element (cone C) in an upright position on a road surface G of a road, and as a traffic cone collection device for collecting the cone-shaped road barrier element that is set up in an upright position on the road surface G of the road. Therefore, in the following description, the traffic cone setup device and the traffic cone collection device are described by the traffic cone setup device / traffic cone collection device 1, 100. When the traffic cone setup device / traffic cone collection device 1, 100 is used both as a traffic cone setup device and as a traffic cone collection device, some of the elements must be exchanged as described below.

[0023] The traffic cone setup device / traffic cone collection device 1, 100 comprises, as a traffic cone setup device, a stand for setting up the cone-shaped road barrier element (hereinafter referred to as "cone C") in an upright position on the road surface G of the road and a coupling 70, 170 for connecting the stand to a lateral outer surface of a loading platform 6, 106 of a vehicle 4, 104. Furthermore, the traffic cone setup device / traffic cone collection device 1, 100, as a traffic cone collection device, comprises a retrieval device for collecting the traffic cone C and the coupling 70, 170 for connecting the retrieval device to the lateral outer surface of the loading platform 6, 106 of the vehicle 4, 104. The stand and the retrieval device share most of their configurations, as described below, and in particular, the stand and the retrieval device are referred to as the stand / retrieval device 10. 110 described.Furthermore, the coupling 70, 170 is identical for the traffic cone setting device and the traffic cone collection device. It should be noted that vehicle 4, 104 is assumed to be a truck, which can generally be loaded with a large number of traffic cones C on the loading platform 6, 106 and has an open side of the loading platform 6.

[0024] The erector / retraction device 10, 110, which serves as an erector, is formed from wheels 18, 118, an erector section 20, a lowering device, a sliding device 50, 150, and the like. The wheels 18, 118 are in contact with the road surface G and cause the erector / retraction device 10, 110, which serves as an erector, to move. The traffic cone C is placed in an upright position on the erector section 20, which does not necessarily have to be flat, as long as the traffic cone C can be placed in an upright position. The lowering device lowers the erector section 20 from a height of the loading platform 6, 106 of the vehicle 4, 104 to a height at which no contact with the road surface G is made, and is in particular a lifting and lowering device 30, 130.The sliding device 50, 150 pushes the guide cone C placed on the setup section 20 away from the setup section 20.

[0025] In a basic method of use of the traffic cone setting device / traffic cone collection device 1, 100, which is put into operation as a traffic cone setting device, the traffic cone C is first set upright on the setting section 20 in a state in which the setting section 20 is at the same height as the loading platform 6, 106 of the vehicle 4, 104. Here, the height of the loading platform 6, 106 is a height of the setting section 20 that is suitable for a worker on the loading platform 6, 106 of the vehicle 4, 104 to pick up a traffic cone C from the loading platform 6, 106 and place the traffic cone C in a state in which a large number of traffic cones C are loaded on the loading platform 6, 106.

[0026] Then, the mounting section 20, on which the traffic cone C is mounted, is lowered from the height of the loading platform 6, 106 of the vehicle 4, 104 to a height at which no contact with the road surface G is made, by means of the lifting and lowering device 30, 130, which serves as the lowering device. The height at which no contact with the road surface G is made is preferably a height at which the road surface G is as close as possible, and is preferably a height up to the outermost limit at which the mounting section 20 does not make contact with the road surface G due to irregularities in the road surface G.

[0027] In a state where the mounting section 20, on which the traffic cone C is mounted, is lowered from the height of the loading platform 6, 106 of the vehicle 4, 104 to a height at which no contact with the road surface G is made, the traffic cone C is pushed from the top of the mounting section 20 towards the road surface G by the sliding device 50, 150, and the traffic cone C is placed in an upright position on the road surface G. Thus, the traffic cone C is erected (installed).

[0028] Next, the erector / retrieval device 10, 110, which serves as the retrieval device for the traffic cone erector / traffic cone collection device 1, 100, is formed from the wheels 18, 118, a tipping arm 60, 160, a retrieval rod 28, 128, a lifting device, and the like. The wheels 18, 118 are as described above. The tipping arm 60, 160 tips over the traffic cone C standing upright on the road surface G. The retrieval rod 28, 128 is inserted into an inner side of the traffic cone C tipped over by the tipping arm 60, 160 and engages with the toppled traffic cone C. The lifting device raises the retrieval rod 28, 128 and is, in particular, the lifting and lowering device 30, 130.

[0029] As the basic method of operation for the traffic cone erection device / traffic cone collection device 1, 100, which is put into operation as a traffic cone collection device, the vehicle 4, 104 is first brought towards the traffic cone C standing upright on the road surface G of the road, and the traffic cone C standing upright on the road surface G of the road is knocked over by the tipping arm 60, 160. Next, the traffic cone C knocked over by the tipping arm 60, 160 is hooked onto the recovery pole 28, 128, and the recovery pole 28, 128, to which the knocked-over traffic cone C is hooked, is raised by the lifting and lowering device 30, 130, which serves as a lifting device, to the height of the loading platform 6, 106 of the vehicle 4, 104.Here, the height of the loading platform 6, 106 is a height suitable for the worker on the loading platform 6, 106 of the vehicle 4, 104 to hold the raised traffic cone C with one hand, to remove the traffic cone C from the catch pole 28, 128 and to stack the traffic cone C on the loading platform 6, 106.

[0030] The coupling 70, 170 for coupling the lifting / retracting device 10, 110 on the lateral outside of the loading platform 6, 106 of the vehicle 4, 104 comprises a loading platform-side mounting section 72, 172, which is locked and fastened to the loading platform 6, 106 of the vehicle 4, 104; a lifting / retracting device-side mounting section 90, 190, which is a lifting / retracting device-side mounting section and a retracting device-side mounting section, which is fastened to the lifting / retracting device 10, 110 on the side of the vehicle 4, 104; and a coupling arm 94, 194, which is provided via the loading platform-side mounting section 72, 172 and the lifting / retracting device-side mounting section 90, 190, which are arranged in a vertical positional relationship. is.

[0031] In coupling 70, 170, one end of the coupling arm 94, 194 is pivotally attached to the load platform-side mounting section 72, 172 via a rotary damper 84, 184. The other end of the coupling arm 94, 194 is further pivotally attached to the mounting section 90, 190 on the erector / retractor-side mounting section via a rotary damper 92, 192. With this configuration in coupling 70, 170, the load platform-side mounting section 72, 172 and the erector / retractor-side mounting section 90, 190 are pivotally connected to each other by the coupling arm 94, 194. Coupling 70, 170 with this configuration has a simple structure, is cost-effective, can be installed on many trucks and similar vehicles, and eliminates the need for a special vehicle.

[0032] The traffic cone setting device / traffic cone collection device 1, 100, which is the traffic cone setting device and the traffic cone collection device with such a configuration and such basic movements, has the advantage that it has a simpler structure and is more cost-effective than a conventional traffic cone setting device / traffic cone collection device. Design 1

The sliding plate 52 is normally upright in the same position as the upright plate 24 of the erecting section 20, and when the guide cone C described below is pushed, the sliding plate 52 is pushed into an erecting plate groove 22a provided in the erecting plate 22 by a movement of the solenoid 54.

[0045] Next, the movements and use of the traffic cone setting device / traffic cone collection device 1, which serves as a traffic cone setting device, will be described using the Fig. 5A to 8 described. Fig. 5A to 8 do not show a description of vehicle 4 and coupling 70.

[0046] First, as in the Fig. 5A and Fig. Figure 5B shows the guide cone C in an upright position on the mounting plate 22 of the mounting section 20 in a state where the mounting section 20 is at the height of the loading platform 6 of the vehicle 4. Then, as indicated by an arrow in Fig. 5A indicates that the mounting section 20 (mounting plate 22), on which the traffic cone C is mounted, is lowered from the height of the loading platform 6 of the vehicle 4 to the height at which no contact with the road surface G is made, by using the lifting and lowering device 30 as a lowering device, as shown in Fig. 6A and Fig. 6B is shown.

[0047] The timing for lowering the support section 20 (support plate 22), on which the traffic cone C is placed at the height of the loading platform 6, can be set by the worker directly operating the lifting and lowering device 30. Alternatively, the support section 20 can be lowered automatically. For example, a lowering control device (not shown) can be provided that initiates the lowering of the support section 20 by the lifting and lowering device 30 when the lowering control device detects that the traffic cone C on the support section 20 is in a position where it is at the height of the loading platform 6 of the vehicle 4. By providing the lowering control device, the worker can simply place the traffic cone C on the storage area 20 (storage plate 22), thus simplifying the task.

[0048] Next, in the state in which the mounting section 20, on which the traffic cone C is mounted, is lowered from the height of the loading platform 6 of the vehicle 4 to the height at which no contact with the road surface G is made (see Fig. 6A and Fig. 6B), the guide cone C is pushed from the top of the mounting section 20 (mounting plate 22) by the sliding device 50 onto the road surface G. In particular, the electromagnet 54 of the sliding device 50 pushes the sliding plate 52 out, and as in Fig. As shown in Figure 7, the sliding plate 52 presses the guide cone C on the mounting plate 22 from the top of the mounting section 20 (mounting plate 22) onto the road surface G. Then, as shown in Fig. As shown in Figure 8, the traffic cone C, pushed out of the mounting section 20 (mounting plate 22) by the sliding device 50, is dropped onto the road surface G and is also pushed away from the height of the loading platform 6 of the vehicle 4, along with the mounting section 20, which is at a height where no contact with the road surface G is made. This causes the traffic cone C to be placed upright on the road surface G. At this point, the vehicle 4 is moving in a direction opposite to the direction in which the traffic cone C is being pushed out (the mounting / retrieval device 10 is also moving in a direction opposite to the direction in which the traffic cone C is being pushed out), and thus the traffic cone C is placed upright on the road surface G and remains there.

[0049] It should be noted that the timing at which the pushing device 50 pushes the traffic cone C from the top of the mounting section 20 (mounting plate 22) onto the road surface G can be controlled by a device that automatically performs a control operation according to the driving condition and the like of the vehicle 4 (mounting / returning device 10). However, the present disclosure is not limited to the case in which the control is performed automatically, and the operator can determine the pushing time. In particular, a pushing command switch (not shown) can be provided to give the pushing device 50 a command at the time of pushing the traffic cone C onto the road surface G. Automation requires a complex and expensive mechanism, but with the pushing command switch, the timing for pushing the traffic cone C can be set in a simple and cost-effective manner.

[0050] After the deployment of the traffic cone C (placing the traffic cone C on the road surface G) is complete, the sliding plate 52 is returned to its starting position, and the empty mounting section 20 is raised and lowered back to the height of the loading platform 6 by the lifting and lowering device 30. The worker then places the traffic cone C again on the mounting section 20 (mounting plate 22), as described above, and repeats the placement of the traffic cone C on the road surface G. Meanwhile, the vehicle 4 is moved in a direction opposite to the direction in which the traffic cone C is being deployed (forward direction of vehicle 4 in the case of vehicle 4 in Fig. 1) (The erector / retractor 10 also moves in a direction opposite to the direction in which the traffic cone C is extended). By repeating the sequence of movements, several traffic cones C can be continuously erected at a predetermined distance on the road surface G. Design 2

[0051] Next, the traffic cone setting device / traffic cone collection device 1 will be presented as an example of the traffic cone collection device using the Fig. Figures 9 to 16 describe in detail. The construction of the traffic cone setting device / traffic cone collection device 1 is as described above, and the description is omitted if a component has the same reference numeral as in the drawings already described in embodiment 1. One difference between embodiment 1 and embodiment 2 is that the setting section 20 is provided in the traffic cone setting device / traffic cone collection device 1, which serves as a traffic cone setting device, while the toppling arm 60 and the recovery rod 28 (including an upright plate 26) are instead provided in the traffic cone setting device / traffic cone collection device 1, which serves as a traffic cone collection device.It should be noted that the setting section 20, the tipping arm 60 and the recovery pole 28 (including the upright plate 26) are exchanged depending on whether the traffic cone setting device / traffic cone collection device 1 is used as a traffic cone setting device or as a traffic cone collection device.

[0052] The tipping arm 60 of the traffic cone setting device / traffic cone collection device 1, which serves as a traffic cone collection device, tips over the traffic cone C standing upright on the road surface G and is arranged on a side that is closest to the traffic cone C standing upright on the road surface G and is to be retrieved in the direction of travel of the traffic cone setting device / traffic cone collection device 1. In particular, as shown in Fig. Figure 11 shows an example of the toppling arm 60 in embodiment 2. The toppling arm 60 is made from a rod that is curved in an M-shape in a plan view and is designed to project towards the side of the traffic cone C standing upright on the road surface G and in the direction of travel of the traffic cone setting / collecting device 1 in a state in which both ends of an M-shaped section 60a, which has an M-shape, extend as linear sections 60b and are provided over the two frames 12. Furthermore, a height at which the toppling arm 60 extends horizontally is defined as a height described below, at which the toppling arm 60 rests against the traffic cone C standing upright on the road surface G and the traffic cone C is toppled.

[0053] As in the Fig. As shown in Figures 10 to 12, the retrieval pole 28 is arranged between the two frames 12 and projects horizontally from the side of the lifting and lowering device 30, which is the lifting device, in the direction of the traffic cone C standing upright on the road surface G and in the direction of travel of the traffic cone erection / collection device 1, in which the traffic cone is to be retrieved. One end on a fixed side (side of the lifting and lowering device 30) of the retrieval pole 28 is attached to the upright plate 26, and the upright plate 26 is connected to the chain 34 of the lifting and lowering device 30 via the connecting section 36. The other end of the retrieval pole 28 is open.

[0054] The upright plate 26 is attached to the guide 42, which is pivotally held by the two guide rods 40. The recovery rod 28 (upright plate 26) can then be raised and lowered by moving the chain 34 of the lifting and lowering device 30 into a position in which the recovery rod 28 (upright plate 26) is pivotally held by the guide rod 40.

[0055] Next, the movements and use of the traffic cone setting device / traffic cone collection device 1, which serves as a traffic cone collection device, will be described using the Fig. Described in sections 13A to 16. Fig. Items 13A to 16 do not contain a description of vehicle 4 and coupling 70.

[0056] First, the vehicle 4, i.e., the erector / return device 10, which serves as a return device, is caused to move towards the traffic cone C standing upright on the road surface G. Then, as in the Fig. 13A and Fig. Figure 13B shows a V-shaped section 60aa of the M-shaped section 60a of the toppling arm 60 against an upper section of the traffic cone C standing upright on the road surface G. At this point, the upper part of the traffic cone C moves towards the center of the V-shaped section 60aa of the M-shaped section 60a of the toppling arm 60 due to its V-shape, even if the upper part of the traffic cone C is not in the center of the V-shaped section 60aa of the M-shaped section 60a of the toppling arm 60, and a Fig. The position relationship shown in Figure 13B is achieved. It should be noted that the shape of the tipping arm 60 does not necessarily have to be M-shaped, as long as the traffic cone C can be tipped and brought into a state in which it is hooked onto the recovery pole 28, but if the shape is M-shaped, the recovery of the traffic cone C can be achieved more reliably.

[0057] When vehicle 4 moves the support / return device 10, as shown in Fig. As shown in Figure 14, the toppling arm 60 begins to tip the traffic cone C, and the traffic cone C is tipped over. When the erector / return device 10 moves towards the tipped traffic cone C, as shown in Figure 14, the toppling arm 60 begins to tip the traffic cone C. Fig. As shown in Figure 15, the retrieval rod 28 is inserted into the inside of the overturned traffic cone C. In this way, the overturned traffic cone C is hooked onto the retrieval rod 28.

[0058] Next, the recovery pole 28, which engages the overturned traffic cone C, is raised to the height of the loading platform 6 of vehicle 4 by the lifting and lowering device 30, which is the lifting device. As in Fig. As shown in Figure 16, the worker, in a state where the traffic cone C is raised by the retrieval pole 28 to the height of the loading platform 6 of the vehicle 4, removes the traffic cone C from the retrieval pole 28 and retrieves the traffic cone C. The retrieved traffic cone C is moved to the loading platform 6 of the vehicle 4.

[0059] It should be noted that the timing of the lifting of the recovery pole 28, in a state where the traffic cone C is engaged from a position on the road surface G, can be controlled by using a device for automatically executing a control such that the recovery pole 28 is automatically lifted when it is detected that the recovery pole 28 is engaging the traffic cone C. However, the present disclosure is not limited to the case where the control is automatic, and the worker can determine the timing for lifting the recovery pole 28. In particular, a lifting start command switch (not shown) can be provided to give a command to the lifting and lowering device 30 at the time of lifting the recovery pole 28.Automation requires a complex and expensive mechanism, but the timing for raising the recovery pole 28 can be set simply and cost-effectively using the raising start command switch. The raising start command switch can also be used to raise the recovery pole 28 in a state where two guide cones C are engaged.

[0060] It should be noted that the traffic cone setting device / traffic cone collection device 1 can be attached to either outer side of the loading platform 6 of the vehicle 4, and that the side to be used can be freely chosen, depending on where the traffic cone C is to be placed in relation to the road, and so on. The orientation of the setting device / retrieval device 10 can also be freely determined by the side of the outer flanks of the loading platform 6 of the vehicle 4 on which the traffic cone setting device / traffic cone collection device 1 is attached, depending on the setting direction and the collection direction of the traffic cone C. embodiment 3

[0061] Next, the traffic cone setting device / traffic cone collection device 100 is described, which has the same basic structure as the traffic cone setting device / traffic cone collection device 1, but is partially modified, using the Fig. 17 and Fig. 18. However, since the difference in the description of the traffic cone setting device / traffic cone collection device 100, which serves as a traffic cone collection device, is more pronounced than in the description of the traffic cone setting device / traffic cone collection device 1, the description of the traffic cone collection device is given primarily. It should be noted that the movements of the traffic cone setting device / traffic cone collection device 100 are similar to those of the traffic cone setting device / traffic cone collection device 1.

[0062] Initially, the frames 112 of the erector / retrieval device 110 of the traffic cone erector / traffic cone collector device 100 have the same shape as the frames 12 of the traffic cone erector / traffic cone collector device 1, and a strut 114 and a strut 116, which connect the left and right frames 112, resemble the strut 14 and the strut 16 of the traffic cone erector / traffic cone collector device 1. However, the wheels 118 have a larger diameter than the wheels 18 of the traffic cone erector / traffic cone collector device 1 and are arranged so that they project far beyond the sides of the frames 112. The wheels 118, with a relatively large diameter, are arranged so that they extend far beyond the sides of the frames 112, enabling the erector / retrieval device 110 of the traffic cone erector / collecting device 100 to move stably on the road surface G. As in Fig. As shown in Figure 17, the loading platform 106 of the vehicle 104, on which the traffic cone erector / collecting device 100 is installed, is located directly next to a rear wheel 104b and not, as in the example of the traffic cone erector / collecting device 1, in the middle between a front wheel 104a and the rear wheel 104b. The traffic cone erector / collecting device 100 is positioned on the loading platform 106 directly next to the rear wheel 104b, so that the traffic cone erector / collecting device 100 follows the vehicle 104 more stably even when the vehicle 104 is driving in a serpentine pattern, and performs the erection and retrieval of the traffic cone C.

[0063] It should be noted that an upright plate 126, the recovery rod 128, the lifting and lowering device 130, a motor 132, a connecting section 136, a cover 138, a guide rod 140, a guide rod holder 140a and a guide 142 have the same structure as the traffic cone setting device / traffic cone collection device 1.

[0064] With regard to the sliding device 150, the sliding plate 52 is moved in the traffic cone setting device / traffic cone collection device 1 using the solenoid 54, while a sliding plate 152 is moved in the traffic cone setting device / traffic cone collection device 100 by a drive 156 with chain structure and using a motor 154 as a drive source. In this way, the traffic cone setting device / traffic cone collection device 100 can only be set in motion by electricity.

[0065] The toppling arm 160 has a shape in which a round bar is bent in plan view into an essentially M-shape, which in its basic form resembles the traffic cone setting device / traffic cone collection device 1, and has a structure in which a linear section 162 extends from an essentially M-shaped end section of each of the frames 112 and is detachably attached. An M-shaped section 160a and a V-shaped section 160aa of the toppling arm 160 also resemble the shape of the toppling arm 60 of the traffic cone setting device / traffic cone collection device 1, but the toppling arm 160 is provided with a projecting front section 160b, which projects in an essentially U-shape on each of the two outer sides of the linear section 162 on a direction-of-movement side of the toppling arm 160.The forward section 160b of the overturning arm 160 gives it a shape with which the guide cone C can be reliably tipped in front of the recovery pole 128.

[0066] The coupler 170 has a structure that differs slightly from that of the coupler 70 of the traffic cone erector / traffic cone collector 1. In particular, a height adjuster 174 is provided on an upper section of the loading platform-side mounting section 172, which sets a height from a loading platform-side plate 108. Furthermore, a basic structure in which the coupling arm 194 is pivotably arranged between the loading platform-side mounting section 172 and the erector / return device-side mounting section 190 via the rotary dampers 184 and 192 resembles the coupler 70 of the traffic cone erector / traffic cone collector 1. However, as can be seen from Fig.As can be seen in Figure 17, the coupling arm 194, in contrast to the coupling arm 94 of the traffic cone setting device / traffic cone collection device 1, is designed to be suspended vertically.

[0067] The foregoing describes some exemplary embodiments for illustrative purposes. Although the preceding discussion has presented specific embodiments, it will be clear to those skilled in the art that changes in form and detail can be made without departing from the general spirit and scope of the invention. Accordingly, the description and the drawings are to be regarded as illustrative rather than limiting. This detailed description is therefore not to be understood in a limiting sense, and the scope of the invention is defined only by the claims contained therein, together with the entire range of equivalents to which such claims refer.
