Description

Technical Field

[0001] The present invention relates to a mechanism for storing a cone bar in a load cone (so-called color cone: registered trademark).

Background Art

[0002] When a construction vehicle or the like enters or exits in a state where load cones and cone bars are arranged alternately, it is necessary to move the load cones and cone bars to secure a "space for the construction vehicle to enter and exit".

[0003] Specifically, as shown in FIG. 16(A), one load cone 50 and two cone bars 60, 60 on both sides thereof are moved, and as shown in FIG. 16(B), a space for a construction vehicle 70 (such as a 2t - 4t truck) to enter and exit is secured. Also, as shown in FIGS. 17(A) to (B), when the construction vehicle 71 is large-sized (such as a 10t-class truck), two load cones 50 and three cone bars 60 are moved to secure a space.

[0004] At this time, since the removed cone bar will interfere with the guidance if it is "held in the hand", in most cases, it will be "left on the road".

[0005] In that case, there are the following problems. (1) When the cone bar is laid horizontally on the road, a thickness of about 4 cm (the diameter of the cone bar) becomes a step, and there is a risk that pedestrians and bicycles may fall. (2) When the cone bar is laid horizontally on the road, a rod with a length of about 1.5 m to 2.0 m (the length of the cone bar) is in a state of "occupying a place" on the road, so there is a risk of interfering with the progress of pedestrians and bicycles. (3) When moving the road cone and cone bar, one hand holds the road cone and the other holds the cone bar, leaving both hands occupied. This means that if you need to blow a whistle or give a hand signal to warn of danger, you will have to let go of one of your hands, which will delay your ability to warn of danger. (4) Placing the cone bars "on the road" can cause them to become dirty with soil and sand, making the work site look unsightly. (5) Cone bars are often thrown when "placing them on the road," making them prone to breaking. (6) If the cone bars are placed on the road, they will be blown away and scattered by the wind.

[0006] On the other hand, although slightly different from the above problems, Patent Document 1 discloses an invention that incorporates a cone bar tape (tape-shaped cone bar) into a traffic cone (road cone) in order to solve the following problems: "When attaching cone bars to traffic cones, there was a problem that it was time-consuming and troublesome to take out the cone bars one by one from the work vehicle. Cone bars are long and difficult to take out from the work vehicle. Also, when working with multiple cone bars on the road, there was a problem that the cone bars being held would be dropped. Dropping cone bars on a busy roadway is extremely dangerous." (Detailed description of the invention in Patent Document 1

[0005] and

[0006] ). [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2020-84523 [Patent Document 2] Patent No. 7162319 [Overview of the project] [Problems that the invention aims to solve]

[0008] The invention described in Patent Document 1 solves the problem by embedding the cone bar tape inside the traffic cone, but instead of using a typical rigid cone bar, it uses a retractable cone bar tape. Furthermore, because the cone bar tape is embedded inside the traffic cone, one of the advantages of a traffic cone, "stackable" (= compact storage, handling, and transport), is not possible, which is a disadvantage.

[0009] In response to this, the inventor of the present invention pondered how to solve the above problems while continuing to use the rigid cone bars that are currently widely used. As a result, he arrived at the idea of ​​"storing the cone bar in an upright position" within the road cone, and invented the invention described in Patent Document 2. And now, after further consideration, he has completed the present invention. [Means for solving the problem]

[0010] First, the first to fourth inventions of the present invention relate to a first part for storing a cone bar, which is attached to and used with existing road cones. The first invention is a first part for storing a cone bar, which is used to house a cone bar installed between the main bodies of a road cone having a conical main body, and is characterized in that the first part body, which is attached to the upper end of the main body of the road cone, is provided with one or more locking parts for locking a locking part provided on the cone bar. The second invention is a first cone bar storage part according to the first invention, characterized in that the inner surface of the first part body facing the upper end of the main body of the road cone is provided with a convex portion that contacts the upper end. The third invention is a first part for storing a cone bar according to the first or second invention, characterized in that the locking portion is slit-shaped. The fourth invention is a first cone bar storage part according to the third invention, characterized in that the inner surface of the first part body facing the upper end of the main body of the road cone has a concave portion around the locking portion.

[0011] Next, the fifth and sixth inventions of the present invention relate to a second part for storing a cone bar, which is attached to and used with an existing cone bar. The fifth invention is a second part for storing a cone bar, which is used to store a cone bar installed between the main bodies of a road cone having a conical main body, and is characterized by comprising a base portion that is attached to the rod-shaped bar body of the cone bar, and a locking portion for locking to a locking portion provided on the first part body that is attached to the upper end of the main body of the road cone. The sixth invention is a second cone bar storage part according to the fifth invention, characterized in that the locking portion has a T-shaped cross-section in the short direction that locks with the slit-shaped locking portion of the first part.

[0012] Furthermore, the seventh and eighth inventions of the present invention relate to a cone bar storage parts set (first cone bar storage part + second cone bar storage part) that is attached to and used with existing road cones and cone bars, respectively. The seventh invention is a cone bar storage parts set characterized by comprising a first cone bar storage part according to any of the first to fourth inventions and a second cone bar storage part according to the fifth or sixth invention. The eighth invention is a cone bar storage parts set according to the seventh invention, characterized in that the locking portion of the second cone bar storage part and the locked portion of the first cone bar storage part are locked together so that the cone bars being stored do not interfere with each other. [Effects of the Invention]

[0013] According to the present invention, by attaching the first part for storing the cone bar to an existing road cone and the second part for storing the cone bar to an existing cone bar, the cone bar can be stored in an upright position within the road cone. This allows the above-mentioned problems (1) to (6) to be solved by retrofitting existing road cones and cone bars without having to replace them.

[Modes for carrying out the invention]

[0015] The following describes an embodiment of the cone bar storage structure (mechanism) according to the present invention, based on the drawings. The embodiments described below are merely examples of the present invention and are not limited thereto.

[0016] A first embodiment of the cone bar storage structure according to the present invention is shown in Figures 1 to 7. Figures 1 and 2 are explanatory diagrams relating to the first part for storing the cone bar according to the first embodiment. First, Figure 1 shows the first part (first part) 10 for storing the cone bar, which is attached to the road cone (not shown). As shown in the figure, the first part 10 has a cylindrical first part body 11 with a flared base, and is provided with two slit-shaped locking portions 12, 12 running vertically. The inner surface 13 of the first part body 11 is provided with a plurality of convex portions 14, 14, ... running vertically. The inner surface 14 is also provided with concave portions 15 around the locking portions 12. Reference numeral 16 denotes a mounting hole for attaching the first part 10 to the road cone.

[0017] Next, Figure 2 illustrates the state in which the first part 10 is attached to the existing road cone 1. The road cone 1 has a conical body portion 2, and the first part 10 is attached to its upper end portion 3. At this time, it is preferable that the tip of the first part 10 protrudes from the top portion 4 of the road cone 1. In addition, the first part 10 has a plurality of convex portions 14, 14, ... on its inner surface 13, and these convex portions 14, 14, ... come into contact with the upper end portion 3 of the road cone 1. Furthermore, even with the first part 10 attached, the road cone 1 can be stacked and collected / stored after use, just as in the conventional method.

[0018] Figures 3 and 4 are explanatory diagrams relating to the second part for storing the cone bar in the first embodiment. First, Figure 3 shows the second part (second part) 20 for storing the cone bar (not shown), which is attached to the cone bar. As shown in Figure 3(a), the second part 20 comprises a base portion 21 extending in the longitudinal direction of the cone bar (not shown) and a locking portion 22 provided on the base portion 21. The locking portion 22 is composed of a body portion 23 and a head portion 24 that rise from the base portion 21, and has a T-shaped cross-section in the short direction. Furthermore, the body portion 23 is provided so as to be inclined to the longitudinal direction of the base portion 21, rather than being parallel to it, in relation to the locking portion 22. This is clearly shown in the plan view illustrated in Figure 3(b), and the reason for this will be explained in paragraph

[0022] below. Furthermore, in order to attach the second part 20 to the cone bar (not shown), the base portion 21 is provided with mounting holes 25 for screws, and the locking portion 22 is provided with mounting holes 26 for cable ties. Furthermore, the body portion 23 has a beveled end 27 that is cut down to facilitate insertion of the locking portion 22 into the locked portion 12.

[0019] Next, Figure 4 illustrates the state in which the second part 20 is attached to the existing cone bar. Figure 4(a) shows the second part 20 attached to a non-extendable cone bar. In this case, the second part 20 is attached to the bar body 5 using screws 40, 40, etc., by using the base-side holes 25, 25 of the base part 21. Figure 4(b) shows the second part 20 attached to the telescopic cone bar. In this case, since screws 40 cannot be used due to the telescopic structure of the bar body 6, the holes 26, 26 on the body side of the locking part 22 are used to attach it to the bar body 6b that is to be telescopic using cable ties 41, 41, etc.

[0020] Figures 5 to 7 are explanatory diagrams regarding the storage structure (mechanism) of the cone bar using the first part 10 and the second part 20. First, Figure 5 illustrates the state in which the cone bar 7, to which the second part 20 is attached, is locked to the first part 10 attached to the road cone 1. As shown in Figure 5(a), by inserting the locking portion 22 of the second part 20 into the locked portion 12 of the first part, the locking portion 22 is locked to the locked portion 12, as shown in Figure 5(b), and the cone bar 7 is stored (fixed) in the road cone 1.

[0021] Next, Figure 6 shows a cross-sectional view illustrating the storage structure (mechanism) of the cone bar shown in Figure 5. As shown in the figure, the first part 10 forms a clearance 17 between itself and the upper end 3 of the road cone 1 by a plurality of convex portions 14, 14, ... provided on its inner surface 13. This allows the head 24 of the locking portion 22 of the second part 20 to be inserted into the space of this clearance 17, so that the locking portion 22 is securely locked to the locked portion 12. Furthermore, even if this clearance 17 is insufficient, the inner surface 13 of the first part 10 has a concave portion 15 around the locking portion, which can compensate for the clearance 17. In this embodiment, the clearance is formed by the convex portion 14 and the concave portion 15 of the first part 10, but the clearance may also be formed by only one of the convex portion 14 or the concave portion 15.

[0022] Furthermore, Figure 7 illustrates the state in which the cone bars 7,7 are stored (fixed) in the road cone 1. As shown in the figure, the retracted cone bars 7,7 are housed in the road cone 1 without interfering with each other. This is because the locking portion 22 of the second part 20 is inclined, rather than parallel to the longitudinal direction of the base portion 21. In other words, since the locked portions 12,12 of the first part 10 are located in symmetrical positions, if the locking portion 22 of the second part 20 were parallel to the longitudinal direction of the base portion 21, the cone bars 7,7 would be housed in the same direction (on a line) and would interfere with each other. To avoid this, the locking portion 22 is inclined with respect to the base portion 21. Furthermore, in order to avoid interference between the cone bars 7,7, the base portion 21 and the locking portion 22 may be arranged parallel to each other, and only the locked portions 12,12 may be tilted vertically. Alternatively, the tilt of the base portion 21 and the locking portion 22 may be combined with the tilt of the locked portions 12,12.

[0023] A second embodiment of the cone bar storage structure according to the present invention is shown in Figures 8 to 14. In the following description of the second embodiment, the differences from the first embodiment will be explained, and the explanation of the similarities will be omitted. Similarly, common reference numerals in the drawings will be the same.

[0024] Figures 8 and 9 are explanatory diagrams relating to the first part for storing the cone bar in the second embodiment. The first cone bar storage part (first part) 10' of the second embodiment differs from the first cone bar storage part (first part) 10 of the first embodiment in that the upper end of the first part body 11 is connected by a connecting part 18. This improves the strength of the first part body 11.

[0025] Figures 10 and 11 are explanatory diagrams relating to the second part for storing the cone bar in the second embodiment. The second part (second part) 20' for storing the cone bar in the second embodiment differs from the first part (first part) 20 for storing the cone bar in the first embodiment in that it is further extended from the slope 27 of the body portion 23 to form a contact portion 28. The role of this contact portion 28 will be described in the following paragraph.

[0026] )do.

[0026] Figures 12 to 14 are explanatory diagrams regarding the storage structure (mechanism) of the cone bar using the first part 10' and the second part 20'. As illustrated (especially in Figure 13), by inserting the locking portion 22 of the second part 20' into the locked portion 12 of the first part 10', the locking portion 22 is locked to the locked portion 12, and the cone bar 7 is stored (fixed) in the road cone 1. At this time, the contact portion 28 of the second part 20' first slides toward the locked portion 12 of the first part 10', sliding while contacting the periphery of the locked portion 12. Furthermore, the head portion 24 of the second part 20' slides while contacting the connecting portion 18 of the first part 10'. As a result, there is contact at both the upper part of the first part 10' (contact with the connecting portion 18) and the lower part of the second part 20' (contact with the contact portion 28), making the insertion (sliding) of the locking portion 22 into the locked portion 12 extremely stable. Consequently, this insertion operation becomes easy.

[0027] Figure 15 illustrates another embodiment relating to the locking of the locked portion of the first part 10 and the locking portion of the second part 20. Figure 15(a) shows that the second part 20 is equipped with an L-shaped locking portion 22b, which is locked to a locking portion 12b formed in the first part 10. Figure 15(b) shows that the second part 20 is equipped with an L-shaped locking portion 22b, which is locked to a base-shaped locking portion 12c formed on the first part 10. Figure 15(c) shows that the second part 20 is equipped with an L-shaped locking portion 22b, which is locked to a bent, stand-shaped locking portion 12d formed on the first part 10.

[0028] Although not shown in the diagram, as another embodiment of the locking mechanism between the locking portion of the first part 10 and the locking portion of the second part 20, a magnet or hook-and-loop fastener may be used to lock the locking portion of the first part 10 and the locking portion of the second part 20. [Industrial applicability]
