Description

[Technical Field]

[0001] The present invention relates to a cone bar storage mechanism for storing cone bars in road cones (also known as color cones: registered trademark). [Background technology]

[0002] When road cones and cone bars are lined up alternately, when construction vehicles or the like enter or exit, the road cones and cone bars must be moved to ensure there is space for the construction vehicles to enter and exit.

[0003] Specifically, as shown in Figure 16(A), one road cone 50 and the two cone bars 60, 60 on either side of it are moved to create space for construction vehicles 70 (such as 2-ton to 4-ton trucks) to enter and exit, as shown in Figure 16(B). Also, as shown in Figures 17(A) to (B), when the construction vehicle 71 is large (such as a 10-ton class truck), two road cones 50 and three cone bars 60 will need to be moved to make room.

[0004] At this time, the removed cone bar will get in the way of guidance if it is "held in hand," so in most cases it will be "left on the road."

[0005] In that case, the following problems arise: (1) When cone bars are placed sideways on the road, a step of approximately 4 cm in thickness (the diameter of the cone bar) is created, posing a risk of pedestrians and cyclists falling over. (2) When cone bars are placed sideways on the road, they take up space on the road, with a length of approximately 1.5 to 2.0 meters (the length of the cone bar), creating a risk of obstructing the progress of pedestrians and cyclists. (3) When moving a road cone and a traffic cone bar, both hands are occupied because one hand holds the road cone and the other holds the traffic cone bar. When blowing a horn or making a hand signal to warn of danger, one hand must be released, which delays the act of warning of danger. (4) Placing the cone bar on the road causes dirt and sand to get on it, making the work site look unsightly. (5) Cone bars are often thrown away when "putting them on the road," making them prone to breakage. (6) If you place cones on the road, they will be blown away and scattered when the wind blows.

[0006] On the other hand, although it is slightly different from the above-mentioned problem, Patent Document 1 discloses an invention in which cone bar tape (a tape-like cone bar) is built into a triangular cone (road cone) to solve the following problem: "When attaching cone bars to a triangular cone, there is a problem that it takes time and effort to remove the cone bars one by one from the work vehicle. Cone bars are long, which makes them difficult to remove from the work vehicle. Also, when working on the road while holding multiple cone bars, there is a problem that the cone bars may be dropped. It is extremely dangerous if a cone bar is dropped on a road with heavy traffic." (Patent Document 1, Detailed Description of the Invention,

[0005] and

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

[0007] [Patent Document 1] Japanese Patent Publication No. 2020-84523 [Patent Document 2] Patent No. 7162319 Summary of the Invention [Problem to be solved by the invention]

[0008] The invention of Patent Document 1 solves the problem by incorporating cone bar tape into the cone, but uses a retractable cone bar tape instead of the typical hard cone bar used to embed it inside the cone. Also, because the cone bar tape is embedded inside the cone, it has the disadvantage of not being able to be "stacked" (which allows for compact storage, keeping, and transportation), which is one of the features (convenience) of cones.

[0009] In response to this, the inventors of the present application have been pondering over ways to solve the above problems while still using the hard cone bars that are currently widely used. As a result, they have arrived at the idea of ​​storing the cone bars in an upright position in the road cone, and have invented the invention described in Patent Document 2. Further pondering has now led to the completion of the present invention. [Means for solving the problem]

[0010] First, the first to fourth aspects of the present invention relate to a first part for storing cone bars that is attached to an existing road cone. The first invention is a first part for storing a cone bar, which is used to store a cone bar that is installed between two main bodies of a road cone having a conical main body, and is characterized in that the first part body that is attached to the upper end of the main body of the road cone has one or more engaging portions that engage with engaging portions provided on the cone bar. The second invention is a first part for storing cone bars according to the first invention, characterized in that the inner surface of the first part body that faces the upper end of the main body of the road cone is provided with a convex portion that abuts against the upper end. A third invention is the first part for storing cone burrs according to the first or second invention, characterized in that the locked portion is slit-shaped. The fourth invention is a first part for storing cone bars according to the third invention, characterized in that the inner surface of the first part body that faces the upper end of the main body of the road cone has a recessed portion around the engaging portion.

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

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

[0013] According to the present invention, by attaching a first part for storing cone bars to an existing road cone and a second part for storing cone bars to an existing cone bar, the cone bar can be "stored upright" in the road cone. This makes it possible to solve the above problems (1) to (6) by retrofitting existing road cones and cone bars without having to replace them. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of a cone bar storage structure (mechanism) 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.

[0016] A first embodiment of a cone bar storage structure according to the present invention is shown in FIGS. 1 and 2 are explanatory views of a first part for housing a cone burr according to the first embodiment. First, FIG. 1 shows a cone bar storage first part (first part) 10 to be attached to a road cone (not shown). As shown in the figure, first part 10 has a cylindrical first part body 11 that flares out at the bottom, and two slit-shaped locking portions 12, 12 extending vertically. An inner surface 13 of first part body 11 has a plurality of convex portions 14, 14, ... extending vertically. In addition, inner surface 14 has a concave portion 15 around locking portion 12. Reference numeral 16 denotes an attachment hole for attaching first part 10 to a road cone.

[0017] Next, FIG. 2 illustrates a state in which the first part 10 is attached to an existing road cone 1. The road cone 1 has a conical main body 2, and a first part 10 is attached to its upper end 3. At this time, it is preferable that the tip of the first part 10 protrudes from the top 4 of the road cone 1. The first part 10 also has a plurality of convex portions 14, 14, ... on its inner surface 13, and the upper end 3 of the road cone 1 comes into contact with these convex portions 14, 14, .... Even if the first part 10 is attached to the road cone 1, it can be collected and stored by stacking after use in the same manner as in the conventional case.

[0018] 3 and 4 are explanatory views of the second part for housing the cone burrs in the first embodiment. First, FIG. 3 shows a cone bar storage second part (second part) 20 that is attached to a cone bar (not shown). 3(a), the second part 20 includes 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 stand upright from the base portion 21, and has a T-shaped cross section in the short side direction. The body 23 of the locking portion 22 is provided so as to be inclined rather than parallel to the longitudinal direction of the base portion 21. This is clearly shown in the plan view of Figure 3(b), and the reason for this will be explained in paragraph

[0022] below. In order to attach the second part 20 to a cone bar (not shown), the base part 21 has mounting holes 25 for screws, and the locking part 22 has mounting holes 26 for cable ties. Furthermore, one end of the body 23 is cut down to form a slope 27 to make it easier to insert the locking portion 22 into the locked portion 12.

[0019] Next, FIG. 4 illustrates the state in which the second part 20 is attached to the existing cone bar. 4(a) shows a non-extendable cone bar to which the second part 20 is attached. In this case, the base part side holes 25, 25 of the base part 21 are used to attach the second part 20 to the bar main body 5 with screws 40, 40 or the like. 4(b) shows the second part 20 attached to a telescopic cone bar. In this case, because the telescopic structure of the bar body 6 means that screws 40 cannot be used, the body-side holes 26, 26 of the locking part 22 are used, and the part is attached to the telescopic side of the bar body 6b with cable ties 41, 41 or the like.

[0020] 5 to 7 are explanatory diagrams relating to a storage structure (mechanism) of the cone bar using the first part 10 and the second part 20. FIG. First, FIG. 5 illustrates a 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, FIG. 6 shows a cross-sectional view of the storage structure (mechanism) of the cone bar shown in FIG. 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 virtue of the multiple convex portions 14, 14, ... provided on the 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 the recessed portion 15 around the locked 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 be formed by only either the convex portion 14 or the concave portion 15.

[0022] Furthermore, FIG. 7 illustrates a state in which the cone bars 7, 7 are housed (fixed) in the road cone 1. As shown in the figure, the stored cone bars 7, 7 are stored in the road cone 1 without interfering with each other. This is because the locking portions 22 of the second part 20 are not parallel to the longitudinal direction of the base portion 21 but are inclined. In other words, because the locked portions 12, 12 of the first part 10 are provided in symmetrical positions, if the locking portions 22 of the second part 20 were parallel to the longitudinal direction of the base portion 21, the cone bars 7, 7 would be stored in the same direction (on a line) and would interfere with each other. To avoid this, the locking portions 22 are inclined relative to the base portion 21. In addition, 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 inclined vertically, or a method may be used in which the inclination of the base portion 21 and the locking portion 22 is combined with the inclination of the locked portions 12,12.

[0023] A second embodiment of the cone bar storage structure according to the present invention is shown in FIGS. Hereinafter, the second embodiment will be described with respect to differences from the first embodiment, and a description of commonalities will be omitted. In addition, common parts in the drawings will be denoted by the same reference numerals.

[0024] 8 and 9 are explanatory views of the first part for housing the cone burrs according to the second embodiment. The first part (first part) 10' for storing cone burrs of the second embodiment differs from the first part (first part) 10 for storing cone burrs of the first embodiment in that the upper ends of the first part bodies 11 are connected by connecting portions 18. This improves the strength of the first part bodies 11.

[0025] 10 and 11 are explanatory views of a second part for housing the cone burrs according to the second embodiment. The second part (second part) 20' for storing cone burrs in the second embodiment differs from the first part (first part) 20 for storing cone burrs in the first embodiment in that a contact part 28 is formed by extending further from the inclined surface 27 of the body part 23. The role of this contact part 28 will be described later (paragraph

[0026] )do.

[0026] 12 to 14 are explanatory diagrams relating to a storage structure (mechanism) of the cone bar using a first part 10' and a second part 20'. As shown in the figures (particularly FIG. 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 abutting portion 28 of the second part 20′ first slides into the locked portion 12 of the first part 10′, abutting against the periphery of the locked portion 12. Furthermore, the head 24 of the second part 20′ slides while abutting against the connecting portion 18 of the first part 10′. Therefore, since both the upper part of the first part 10′ (abutting against the connecting portion 18) and the lower part of the second part 20′ (abutting against the abutting portion 28) abut, the locking portion 22 is inserted (slid) into the locked portion 12 with great stability. As a result, this insertion operation is easy.

[0027] FIG. 15 illustrates another embodiment of the locking between the locked portion of first part 10 and the locking portion of second part 20. In FIG. 15(a), second part 20 has L-shaped locking portion 22b, which is locked to locked portion 12b formed as a perforation in first part 10. In FIG. 15(b), second part 20 has L-shaped locking portion 22b, which is locked to stand-shaped locked portion 12c formed on first part 10. In FIG. 15(c), second part 20 has L-shaped locking portion 22b, which is locked to bent, stand-shaped locking portion 12d formed on first part 10.

[0028] Although not shown in the figures, other embodiments for engaging the interlocking portion of the first part 10 with the interlocking portion of the second part 20 may include using a "magnet" or "hook and loop fastener" to interlock the interlocking portion of the first part 10 with the interlocking portion of the second part 20. [Industrial Applicability]

[0029] The cone bar storage structure of the present invention is a cone bar storage technology that is compatible with the hard cone bars that are currently widely used, and can be widely used at construction sites and elsewhere. [Explanation of symbols]
