Description

[Technical Field]

[0001] The present invention relates to a cone bar. [Background Art]

[0002] Conventionally, at construction sites, event venues, and the like, cone bars have been used to block surrounding traffic or form simple alignment passages by bridging between the tips of installed traffic cones. However, since the length of a cone bar is generally about 1 m to 3 m, space for transportation, storage, etc. is required, which has the disadvantage of increasing the cost for securing storage space and the transportation cost when transporting a large number of cone bars to large-scale construction sites or event venues.

[0003] In Patent Document 1, in order to solve the above-mentioned disadvantages, there is disclosed a cone bar having a joint composed of a convex socket and an insert into which the socket is inserted, wherein the cone bar is configured such that bar divided bodies obtained by disassembling a bar main body can be transported and stored, and ends of the disassembled bar divided bodies can be connected to each other at a construction site or the like after transportation.

[0004] Patent Document 2 discloses a cone bar device in which a stretchable main body portion is configured by slidably connecting an inner pipe and an outer pipe, and a stopper mechanism portion that enters and fixes to an overlapping portion where the inner pipe and the outer pipe overlap each other is provided.

Figure 5 is a diagram showing the state of use of Figure 4. Figure 6 is a diagram showing the cone bar in a contained state. Figure 7 is an overall plan view showing a modified example of the cone bar.

[0012] As shown in Figure 1, the cone bar 10 includes a pair of end divisions 11, an intermediate division 12 provided between the pair of end divisions, and a connecting portion 20 that detachably connects the ends of the end divisions 11 and the ends of the intermediate division 12. The cone bar 10 becomes a simple fence that blocks passage between a pair of cones 1 by inserting the cone bar rings 13 provided at both ends of the cone bar through the tips of the installed pair of cones 1.

[0013] The end divided body 11 and the intermediate divided body 12 are bar divided bodies obtained by cutting a cone bar 10 formed in an elongated cylindrical shape at an intermediate portion in the longitudinal direction. In the present embodiment, the intermediate portion in the longitudinal direction of the cone bar 10 is cut at two positions, and three bar divided bodies having substantially the same length are formed. The end divided body 11 is provided at one end with a cone burring 13 that is hooked to the tip of a cone 1, and is formed at the other end side with an opening 11a to which the connecting portion 20 is attached. The intermediate divided body 12 is formed at both ends with openings 12a, 12a to which the connecting portions 20 are attached.

[0014] The connecting portion 20 includes a male connecting portion (first connecting portion) 30 attached to one end side of the end divided body 11, a female connecting portion (second connecting portion) 40 attached to both ends of the intermediate divided body 12, and a connecting string 50 that connects the male connecting portion 30 and the female connecting portion 40. The male connecting portion 30 and the female connecting portion 40 are formed by resin molding.

[0015] The male connecting portion 30 includes a male-side attachment portion 31 formed in a cylindrical shape fitted into the openings 11a, 12a of the end divided body 11 or the intermediate divided body 12, a protruding portion 32 protruding from the male-side attachment portion 31, and a flange-shaped male-side flange portion 33 formed on the outer peripheral surface of the male-side attachment portion 31.

[0016] As shown in FIG. 4, the protruding portion 32 is formed in a bottomed cylindrical shape, and has a male-side opening 32a formed on the tip end side, and a male-side bottom portion 32b formed on the base end side connected to the male-side attachment portion 31. A male-side connecting hole 34 through which the connecting string 50 is inserted is formed in the male-side bottom portion 32b.

[0017] Further, a locking piece 35, which is an annular protrusion, is formed on the outer peripheral surface of the protruding portion 32. The locking piece 35 is arranged closer to the base end (the male-side bottom portion 32b) in the longitudinal direction of the protruding portion 32.

[0018] As shown in FIG. 4, the male-side flange portion 33 has an outer diameter substantially the same as the outer peripheral surfaces of the end divided body 11 and the intermediate divided body 12. The male flange portion 33 acts as a restricting piece that prevents insertion at a predetermined mounting position when the outer surface of the male connecting portion 30 is inserted into the openings 11a and 12a of the end section 11 or the intermediate section 12.

[0019] As shown in Figure 4, the female connector 40 is formed in a bottomed cylindrical shape and has a female opening 40a formed at the tip end, a female bottom portion 40b formed at the base end, and a flange-shaped female flange portion 43 formed on the outer circumferential surface of the female connector 40. A female connecting hole 44 is formed in the female bottom portion 40b through which the connecting string 50 is inserted.

[0020] Furthermore, an annular groove, a locking groove 45, is formed on the inner circumferential surface of the female connector portion 40. The locking groove 45 is located near the longitudinal end (female side opening 40a) of the bottomed cylindrical female connector portion 40.

[0021] As shown in Figure 4, the female flange portion 43 has approximately the same outer diameter as the outer circumferential surfaces of the end portion 11 and the intermediate portion 12. The female flange portion 43 acts as a restricting piece that prevents insertion at a predetermined mounting position when the outer surface of the female connecting portion 40 is inserted into the openings 11a and 12a of the end division 11 or the intermediate division 12.

[0022] As shown in Figure 4, the connecting cord 50 has a stopper 51 formed at one end that is inserted through the male connecting hole 34, and a stopper 51 formed at the other end that is inserted through the female connecting hole 44. In other words, the connecting string 50 connects the male bottom portion 32b and the female bottom portion 40b via the protruding portion 32 of the male connecting portion 30, which is formed in the shape of a bottomed cylinder, and the inside of the cylinder of the female connecting portion 40.

[0023] (Mechanism of Action and Effects) Next, the operation and effects of the cone bar 10 described above will be explained based on Figures 1, 5, and 6. As described above, the cone bar 10 can be switched to a usage state in which the ends of the end sections 11 are connected to both ends of the intermediate section 12 by inserting the male connector 30 into the female connector 40, as shown in Figures 1 and 5. At this time, the locking piece 35 formed on the male connector 30 side is locked into the locking groove 45 formed on the female connector 40 side, thus maintaining the usable state of the cone bar 10.

[0024] On the other hand, as shown in Figures 2 and 6, the cone bar 10 can be switched to a housed state by pulling out the male connector 30 from the female connector 40, thereby separating it into a pair of end sections 11, 11 and an intermediate section 12. In this housed state, the cone bar 10 maintains a state where the ends of the pair of end sections 11 and the end of the intermediate section 12 are connected by a connecting string 50.

[0025] According to this configuration, by switching to the storage state, the cone bar 10 can be divided into three bar sections (a pair of end sections 11 and an intermediate section 12), and folded compactly via the connecting string 50. This makes it easy to store and transport the cone bar 10. Furthermore, as shown in Figure 6, in the retracted state, the cone bar 10 is connected to each other by connecting strings 50, which reliably prevents situations where the cone bar 10 cannot be reassembled into a usable state due to the loss of part of the end section 11 or intermediate section 12.

[0026] Furthermore, by forming the protruding portion 32 on the male connecting portion 30 side into a bottomed cylindrical shape with one end open, as shown in Figure 5, when the cone bar 10 is switched to the usage state, the bent connecting string 50 is smoothly accommodated in the space within the protruding portion 32. This prevents the connecting string 50 from getting caught between the male connecting part 30 and the female connecting part 40 when inserting the male connecting part 30 into the female connecting part 40 to connect the connecting parts 20, thus preventing proper insertion. As a result, the connection work of the connecting parts 20 becomes easier and smoother.

[0027] Furthermore, both ends of the connecting cord 50 are formed with a knot 51 when inserted through the male connecting hole 34 and the female connecting hole 44. As a result, when the cone bar 10 is switched to the operating state, the connecting string 50, which is housed within the protruding portion 32 while bending, pushes the stopper 51 further inward toward the end section 11 and the intermediate section 12. This configuration makes it more reliable to prevent the connecting string 50 from getting caught between the male connecting part 30 and the female connecting part 40, thus making the connection work of the connecting part 20 easier and smoother.

[0028] Furthermore, the cone bar 10 described above is detachably attached by inserting a male connector 30 or a female connector 40 into the openings 11a and 12a of the end section 11 and the intermediate section 12. Therefore, if a part of the end section 11, the intermediate section 12, or the connector 20 is damaged, only the damaged part can be replaced, resulting in excellent maintainability.

[0029] In the above embodiment, the male connector 30 is attached to the opening 11a of the end section 11, and the female connector 40 is attached to the opening 12a on the intermediate section 12 side. However, the configuration is not limited to the above, and one of the connectors 20 may be a male connector 30 and the other a female connector 40. For example, as shown in Figure 7, a female connector 40 may be attached to the ends of a pair of end divisions 11, and male connectors 30 may be attached to both ends of the intermediate division 12.

[0030] Furthermore, in the above embodiment, the cone bar 10 was divided into three bar sections, resulting in a pair of end sections 11, 11 and an intermediate section 12. However, the number of divisions can be two or more, and is not limited to three. For example, the cone bar 10 may be divided into two parts, and the intermediate divider 12 may be omitted, or the cone bar 10 may be divided into four parts, and two intermediate dividers 12 may be provided.

[0031] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate.

[0032] As described above, the following matters are disclosed in this specification: (1) At least two or more bar divisions, It comprises a connecting portion attached to the end of the bar segment, which detachably connects the ends of the bar segments together, The connecting portion comprises a first connecting portion attached to one end of the bar segment, a second connecting portion attached to the other end of the bar segment, and a connecting string connecting the first connecting portion and the second connecting portion. Cone bar. This configuration allows for a simple and low-cost way to switch the cone bar to a compact storage state, reliably preventing the loss of any parts of the bar, thus reducing transportation and storage costs. Furthermore, assembly to the operational state becomes smoother and easier.

[0033] (2) The first connecting portion has a cylindrical mounting portion that fits onto the end of the bar division and a protruding portion that protrudes from the mounting portion, The second connecting portion is formed in the shape of a bottomed cylinder with one end open, its outer circumferential surface fitted to the end of the bar division, and its inner circumferential surface detachably fitted to the protruding portion. The aforementioned protrusion is formed in the shape of a bottomed cylindrical shape with an open tip. Fixing holes are formed in the bottom of the protruding portion and the bottom of the second connecting portion through which the connecting string is inserted. (1) The cone bar described above. With this configuration, when the first connecting part is inserted into the second connecting part to connect them, the bent connecting cord is housed in the space within the protrusion. As a result, the connecting cord is less likely to get caught between the first and second connecting parts, making the connection process of inserting the first connecting part into the second connecting part smoother and easier.

[0034] (3) An annular locking groove is formed on the inner circumferential surface of the bottomed cylindrical second connecting portion. An annular locking piece is formed on the outer circumferential surface of the bottomed cylindrical projection, which is locked into the locking groove. The cone bar as described in (1) or (2). This configuration allows the first and second connecting parts to maintain a connected state during use with a simple setup.
