Description

[Technical Field]

[0001] The present invention relates to a safety cone aid, a marking device, and a method for forming a marking device. [Background technology]

[0002] In construction work, etc., safety cones (also called pylons or triangular cones) and cone bars are sometimes used to mark safe passageways and restricted areas within the construction site, or as a warning device to draw attention to dangerous areas. Safety cones and cone bars are easy to handle and can be easily used as warning devices on construction sites that change daily. Since the height of a safety cone is generally around 700 mm, the height of the cone bar attached to this safety cone is about 600 mm. Therefore, a display device with a cone bar attached to a safety cone can be easily climbed over (stepped over) by a person. For this reason, Patent Document 1 discloses an auxiliary device that is installed on the top of a safety cone, which has a cone head with three parallel peaks formed on a base, and which makes it possible to arrange multiple cone bars side by side using the cone head.When using this auxiliary device, the two cone bars are arranged side by side with a gap between them, making it difficult to straddle. On the other hand, even when the auxiliary device of Patent Document 1 is used, the height of the cone bar is about 600 mm from the ground, and if used to indicate the division between vehicles or heavy machinery and people, it may be difficult for heavy machinery or large vehicles to see. Single-pipe barricades are sometimes used as temporary marking devices, but they require tools to set up and remove, which is more time-consuming than using safety cones.

[0008] In this embodiment, a marking device 1 used to mark safety passages and no-entry areas at construction sites will be described. Fig. 1 shows the marking device 1 of this embodiment. As shown in Fig. 1, the marking device 1 includes a pair of safety cones 2, 2, a pair of cone bars 3, 3 (a first cone bar 31 and a second cone bar 32), and an auxiliary tool 4 for the safety cone. The safety cone 2 comprises a conical body 21 and a base 22 formed at the bottom end of the conical body 21. The conical body 21 is approximately 700 mm high and has a hemispherical upper end. The base 22 is a plate-like portion that protrudes laterally from the bottom edge of the conical body 21. The base 22 is a square with sides of approximately 390 mm, and prevents the safety cone 2 from tipping over. In this embodiment, a weight 7 is placed on the base 22 as needed to prevent the safety cone 2 from tipping over or moving.

[0009] The cone bar 3 is a rod-shaped member that is hung horizontally between a pair of safety cones 2, 2. The cone bar 3 in this embodiment is 2 m long. Hanging portions 33, 33 are formed on both ends of the cone bar 3. The hanging portion 33 is a portion that is hung on the head of the cone body 21, and is annular in shape with an inner diameter equivalent to the outer diameter of the cone body 21 approximately 10 cm from the top end. By inserting the head of the cone body 21 into the hanging portion 33 (i.e., by placing the hanging portion 33 over the head of the cone body 21), it is possible to hang the end of the cone bar 3 on the head of the safety cone 2. In this embodiment, a pair of cone bars 3, 3 are arranged side by side, one above the other, with the lower first cone bar 31 spanning the pair of safety cones 2, 2, and the upper second cone bar 32 being arranged directly above the first cone bar 31 via safety cone auxiliary devices 4 provided on each safety cone 2. In other words, the pair of cone bars 3, 3 are arranged in positions that overlap in a plan view.

[0010] The safety cone auxiliary device 4 is a member that is provided on the top of the safety cone 2 (cone body 21) and that hooks the second cone bar 32. FIG. 2 shows the safety cone auxiliary device 4. The safety cone auxiliary device 4 is made of metal, and as shown in FIG. 2, it has two upper and lower ring-shaped portions 5, 5 and a raised portion 6. The safety cone auxiliary device 4 of this embodiment has a total height of approximately 590 mm, and when installed on the safety cone 2, the height from the ground to the top of the safety cone auxiliary device 4 is approximately 1 m. The ring-shaped portion 5 of this embodiment is formed by cutting a carbon steel pipe to a predetermined length (height).

[0011] The first ring-shaped portion 51, which is the ring-shaped portion 5 arranged on the upper side, is an annular member having an inner diameter larger than the outer diameter of the upper end of the safety cone 2 and smaller than the outer diameter of the middle portion of the safety cone 2. The first ring-shaped portion 51 is arranged around the safety cone 2 below the hook portion 33 of the first cone bar 31. The second ring-shaped portion 52, which is the ring-shaped portion 5 disposed on the lower side, is an annular member having the same central axis as the first ring-shaped portion 51, and is disposed juxtaposed below the first ring-shaped portion 51. The second ring-shaped portion 52 has a larger inner diameter than the first ring-shaped portion 51, and is disposed around the safety cone 2 below the first ring-shaped portion 51.

[0012] The bulky portion 6 is a member extending upward from the first ring-shaped portion 51, and has a shape that allows the hanging portion (end portion) 33 of the cone bar 3 (second cone bar 32) to be hung. The bulky portion 6 of this embodiment is formed by processing a φ6 mm zinc-aluminum alloy rod. The bulky portion 6 of this embodiment includes a pair of connecting portions 61, 61 connecting the first ring-shaped portion 51 and the second ring-shaped portion 52, a pair of widened portions 62, 62 extending upward from the upper end (first ring-shaped portion 51) of the connecting portion 61 in a direction away from the central axis of the first ring-shaped portion 51, and a narrowed portion 63 having an inverted V shape in a front view and extending upward from the upper ends of the pair of widened portions 62, 62. A gap is formed between the widened portion 62 and the outer surface of the cone body 21 of the safety cone 2, allowing the insertion of the hook portion 33 (see FIG. 1) of the cone bar 3. The narrowed portion 63 of this embodiment is formed at the same inclination angle as the outer surface of the cone body 21 of the safety cone 2. The hook portion 33 of the second cone bar 32 is hooked onto the narrowed portion 63.

[0013] A marking device forming method for assembling the marking device 1 of this embodiment will be described below. Figure 3 shows the marking device forming method of this embodiment. As shown in Figure 3, the marking device forming method includes a safety cone arrangement step S1, an auxiliary device installation step S2, a first cone bar attachment step S3, and a second cone bar attachment step S4. Figures 4(a) to (c) show each step of the marking device forming method. As shown in Fig. 4(a), the safety cone installation step S1 is a step of installing a pair of safety cones 2, 2 at a predetermined interval (approximately 2 m) (see Fig. 1). At this time, a weight 7 is placed on the base 22 of the safety cone 2 as needed. As shown in Fig. 4(b), the auxiliary tool installation step S2 is a step of installing the safety cone auxiliary tool 4 on the top of each safety cone 2 (see Fig. 1). The safety cone auxiliary tool 4 is placed from above the safety cone 2 with the top of the safety cone 2 inserted into the inner spaces of the first ring-shaped portion 51 and the second ring-shaped portion 52.

[0014] 4(c), the first cone bar hanging process S3 is a process of hanging the first cone bar 31 on the top of the safety cone 2. When hanging the first cone bar 31, first, the hanging portion 33 is inserted into the space surrounded by the first ring-shaped portion 51 (the top of the safety cone 2) and the bulky portion 6 (the widened portion 62 and the narrowed portion 63) of the safety cone auxiliary device 4. Next, the hanging portion 33 is lowered from above the top of the safety cone 2, and the hanging portion 33 is placed on (mounted around) the top of the safety cone 2. 1, the second cone bar hanging process S4 is a process of hanging the second cone bar 32 on the bulky portion 6 of the safety cone auxiliary device 4. When hanging the second cone bar 32, the hanging portion 33 is lowered from above the safety cone auxiliary device 4 so that the head of the reduced width portion 63 is inserted into the hanging portion 33, thereby hanging the hanging portion 33 on the reduced width portion 63.

[0015] The marking device 1 of this embodiment can be formed simply by combining the safety cone 2, the cone bar 3, and the safety cone auxiliary device 4, and therefore can be easily assembled and is excellent in workability. Furthermore, by installing the second cone bar 32 above the first cone bar 31 at a distance, the cone bar 3 is positioned higher than before, making the display device 1 easier to see. This improves visibility for heavy equipment operators and vehicle drivers, improving safety. Furthermore, since the second cone bar 32 is located at a high position (at a position of about 90 cm from the ground), it is difficult for a person to step over it, and therefore the display device 1 is formed with even greater safety. In addition, by arranging the cone bars 3 in two tiers, one above the other, it takes more effort to remove the cone bars 3 than when there is only one cone bar 3. If it becomes more difficult to remove the cone bars 3, it will discourage people from trying to remove the cone bars 3 and pass through illegally, making it a highly effective safety device.

[0016] The safety cone auxiliary device 4 is lightweight and easy to handle. This allows the marking device 1 to be easily assembled, disassembled, and moved, and it can respond to changes in safety passageways and restricted areas at construction sites as the construction progresses. In addition, the safety cone auxiliary device 4 is formed by combining a rod and an annular member, and is therefore less susceptible to wind loads, preventing the display device 1 from being blown over by the wind and falling over. Since multiple ring-shaped parts 5 are provided around the safety cone 2, it is stable and does not easily come off the safety cone 2.

[0017] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and each of the above-described components can be appropriately modified within the scope of the present invention. In the above embodiment, a case has been described in which a first ring-shaped portion 51 and a second ring-shaped portion 52 are provided, but the number of ring-shaped portions 5 is not limited and may be one, or three or more. In the above embodiment, the first ring-shaped portion 51 and the second ring-shaped portion 52 are formed from carbon steel pipes, but the material from which the first ring-shaped portion 51 and the second ring-shaped portion 52 are made is not limited, and they may be made from, for example, a zinc-aluminum alloy or resin. Also, in the present embodiment, a method of forming the first ring-shaped portion 51 and the second ring-shaped portion 52 by slicing a pipe material (steel pipe) into rings is exemplified, but they may also be formed by bending a bar material or a strip, or by cutting them out from a plate material.

[0018] Furthermore, the first ring-shaped portion 51 and the second ring-shaped portion 52 are not limited to being endless (annular), and may be, for example, C-shaped. In the above embodiment, the bulky portion 6 is formed by processing a zinc-aluminum alloy rod, but there is no limitation on the material that constitutes the bulky portion 6. For example, the bulky portion 6 may be formed by processing an aluminum alloy plate material. The shape of the bulkhead 6 is not limited as long as it can hook the hooking portion 33 of the cone bar 3, and may be, for example, an inverted J-shape as shown in Figure 5(a), or may have a shape in which a portion for placing the hooking portion extends out to the side from the J-shaped member as shown in Figure 5(b).
