Description

[Technical field]

[0001] The present invention relates to a technique for moving road cones (also known as color cones: registered trademark), which are safety devices. [Background technology]

[0002] Road cones are very useful tools that can be used for various purposes. For example, when it is necessary to restrict a certain space, such as at a construction site or an accident site, a restriction line can be easily and quickly set up by lining up road cones on the restriction line and erecting a cone bar between the road cones (Patent Document 1, etc.).

[0003] In this case, multiple road cones need to be transported to the installation site, and then removed after the work is completed. In other words, road cones require the task of "moving." [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6998026 [Patent Document 2] Patent No. 7282410 Summary of the Invention [Problem to be solved by the invention]

[0005] When moving a road cone, it is common to lift it up and move it. On the other hand, road cones have the advantage that they can be stacked, making it possible to move multiple road cones at once.

[0006] However, stacking many road cones together can become quite large and heavy, making it difficult and dangerous to lift and move them all at once. In particular, heavy cones that use high-density materials for the base have become widespread in recent years, and stacking these heavy cones together is so heavy that it is extremely difficult to lift and move them by hand.

[0007] Therefore, the inventors of the present application have pondered over the creation of a technology that can move road cones smoothly, and have completed a groundbreaking movement method (the present invention) that has never been seen before. The present inventors' previous invention, "road cones with a base part with a circular horizontal cross section (Patent Document 2)," makes this road cone movement method (the present invention) even more effective. [Means for solving the problem]

[0008] The first invention of the present application is an auxiliary member for moving a road cone, which is a safety device having a conical main body with a trapezoidal cross section and a base below the main body that is wider than the main body, and is characterized in that it has a grip portion that can be held and an insertion portion that is inserted to fit into an opening provided at the top of the main body of the road cone, and the insertion portion rotates around its axial direction. A second invention is an auxiliary member for a road cone according to the first invention, characterized in that the insertion portion comprises an inner tube connected to the grip portion and an outer tube ring-mounted around the inner tube. A third invention is an auxiliary member for a road cone according to the first or second invention, characterized in that the base portion of the road cone has a circular horizontal cross section. The fourth invention is a method for moving a road cone, which is a safety device having a conical main body with a trapezoidal cross section and a base below the main body that is wider than the main body, comprising: an insertion step of inserting an auxiliary member for a road cone, the auxiliary member having a grip portion that can be held and an insertion portion that is inserted to fit into an opening at the top of the main body of the road cone, the insertion portion rotating around its axial direction, into an opening at the top of the main body of the road cone; a tilting step of tilting the road cone so that the side of the base of the road cone into which the auxiliary member for the road cone has been inserted abuts the installation surface; and a moving step of supporting the tilted road cone by gripping the grip portion of the auxiliary member for the road cone with one hand while pushing out the main body of the road cone with the other hand. A fifth invention is a method for moving a road cone relating to the fourth invention, characterized in that the insertion portion comprises an inner tube connected to the grip portion and an outer tube ring-mounted around the inner tube. A sixth invention is a method for moving a road cone according to the fourth or fifth invention, characterized in that the base of the road cone has a circular horizontal cross section. Effect of the Invention

[0009] The present invention has the following advantages. (1) The auxiliary member for the road cone has a grip portion that can be held, and an insertion portion that is inserted to fit into an opening provided at the top of the main body of the road cone, and the insertion portion rotates around its axial direction to insert the insertion portion into the opening provided at the top of the main body of the road cone, tilting the road cone so that the side of the base of the road cone into which the insertion portion is inserted comes into contact with the installation surface (the surface on which the road cone is to be installed, for example, the ground or floor surface; the same applies to other surfaces), and by supporting the tilted road cone by grasping the grip portion of the auxiliary member for the road cone with one hand (direction) and pushing the main body of the road cone with the other hand (propulsion), the road cone can be moved to the desired location while rolling. (2) The insertion part is composed of an inner tube connected to the grip part and an outer tube that is fitted around the inner tube, so that the outer tube, which is positioned to cover the outer circumference of the immovable inner tube, moves. Therefore, even if the outer tube moves in accordance with the movement (rotation) of the road cone, the inner tube is not affected by the movement of the outer tube, and the worker's hand that grasps the grip part connected to the inner tube is always fixed in a constant position, allowing the worker to safely move the road cone. (3) Since the base of the road cone has a circular horizontal cross section, when the road cone is rolled using the road cone auxiliary member, the arc-shaped side of the base abuts against the installation surface, allowing the road cone to be rolled extremely smoothly, like rolling a tire.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an auxiliary member for a road cone according to the present invention will be described with reference to the drawings. The embodiment described below is an example of the present invention, and the present invention is not limited to this embodiment.

[0012] 1 to 4 are explanatory diagrams illustrating a first embodiment of an auxiliary member for a road cone according to the present invention. First, FIG. 1 is an external view of an auxiliary member 10 for a road cone, and FIG. 2 is a cross-sectional view of the auxiliary member 10 for a road cone. As shown in the figure, the auxiliary member 10 for a road cone is rod-shaped and includes a grip portion 11 for gripping (grasping possible) and an insertion portion 15 for inserting into a road cone. The grip portion 11 has an anti-slip mechanism 12 having an uneven shape on a part of the axial direction, and a round hole 13 for a strap and a long hole 14 for a hook on the rear end side of the auxiliary member 10 for a road cone.

[0013] The insertion part 15 is composed of an inner tube 16 connected to the grip part 11, and an outer tube 17 attached to the inner tube 16. The outer tube 17 attached to cover the outer periphery of the inner tube 16 is movable relative to the immovable inner tube 16. This allows the insertion part 15 to have a structure in which the outer tube 17 rotates around its axial direction. A brim-shaped flange portion 18 is provided in the circumferential direction at the boundary between the insertion portion 15 and the grip portion 11 to act as a restricting portion when the insertion portion 15 is inserted into the road cone.

[0014] Next, Figs. 3 and 4 are views illustrating the usage state of the auxiliary member 10 for a road cone. 3 illustrates the process of inserting the road cone auxiliary member 10 into the road cone 20 (insertion process). As illustrated, the road cone 20 has an opening 23 at the top 22 of a conical main body 21 with a trapezoidal longitudinal section so that a safety light, a flashing light, or the like (not illustrated) can be attached. The insertion portion 15 of the road cone auxiliary member 10 is inserted into this opening 23. At this time, the insertion portion 15 is inserted so as to fit into the opening 23, and the flange portion 18 of the road cone auxiliary member 10 comes into contact with the top 22 of the road cone 20, completing the insertion of the road cone auxiliary member 10.

[0015] 4 illustrates a process of tilting the road cone 20 (tilting process) and a process of moving the road cone 20 (moving process) using the road cone auxiliary member 10. Note that Fig. 4(A) is a front view of the process, and Fig. 4(B) is a top view of the process.

[0016] Among the multiple road cones 20 (five in the figure) stacked for movement, the road cone auxiliary member 10 is inserted into the opening 23 of the topmost road cone 20, and the road cone 20 is tilted (tilting step) while holding the grip portion 11. Then, the side portion 26 of the base portion 25 formed wider than the main body portion 21 on the lower side of the main body portion 21 of the road cone 20 comes into contact with the installation surface 50 on which the road cone 20 is placed.

[0017] Then, the road cone 20 can be easily moved by pushing the road cone 20 forward while placing the other hand, other than the hand holding the grip portion 11, on the main body 21 of the road cone 20 (moving step). Here are the key points: (1) Because the base 25 of the road cone 20 has a circular horizontal cross section, the side 26 of the base 25 that comes into contact with the installation surface 50 is arc-shaped (R-shaped), and the road cone 20 rolls smoothly on the installation surface 50. Therefore, as long as the base 25a of at least the bottom road cone 20 out of the multiple road cones 20 stacked has a circular horizontal cross section, this movement process will go well. Note that the base 25a that comes into contact with the installation surface 50 does not necessarily have to have a "circular horizontal cross section," and the movement process is possible even if it has a "square horizontal cross section." However, a "circular horizontal cross section" is preferable because it allows for smoother rolling. (2) When the road cone 20 is pushed out with a hand placed on the main body 21 of the road cone 20, the outer tube 17 of the insertion portion 15 of the auxiliary member 10 for the road cone inserted into the road cone 20 rotates in conjunction with the push, so that the grip portion 11 does not rotate and the road cone can be held as is. (3) This road cone moving means (moving method) plays a role in controlling the “direction” of the road cone 20 as it is moved by the hand holding the grip portion 11, and in controlling the “propulsion force (speed)” of the road cone 20 as it is moved by the hand attached to the main body portion 21 of the road cone 20.

[0018] FIG. 5 is an explanatory diagram illustrating a second embodiment of the auxiliary member for a road cone according to the present invention. The auxiliary member 30 for a road cone of the second embodiment shown in FIG. 5 is substantially the same as the auxiliary member 10 for a road cone of the first embodiment shown in FIGS. The difference is that the road cone auxiliary member 10 has a grip portion 11 and an insertion portion 15 formed in a straight line, whereas the road cone auxiliary member 30 has a grip portion 31 formed at an angle (in a dogleg shape) to the insertion portion 35. By angling the grip portion 31, it becomes easier for some workers to hold the grip portion 31. The other structure of the auxiliary member 30 for road cones is the same as that of the auxiliary member 10 for road cones, so the description thereof will be omitted. [Industrial Applicability]

[0019] The road cone auxiliary member and road cone moving method of the present invention can be widely used at construction sites and elsewhere as a technique for moving road cones (especially multiple stacked road cones). [Explanation of symbols]
