Description

Technical Field

[0001] The present invention mainly relates to a support leg for a barricade used at a construction site or the like.

Background Art

[0002] At a road construction site or the like, it is common to install a barricade to prohibit entry, and a support leg for a barricade that can be installed by spanning a single pipe as a tool for easily constructing a barricade is widely known. In addition, as this type of barricade, a plastic one that is lightweight, easy to carry, and difficult to cause injury even when a pedestrian hits it has recently become mainstream.

[0003] On the other hand, at a road construction site, traffic guidance of automobiles (for example, lane change, etc.) is often required, and security guards are often arranged. However, when security guards cannot be arranged in terms of labor costs, etc., guiding arrow boards or the like are often installed. Conventionally, a technique of attaching a light reflecting material to a support leg for a barricade to give it the function of an arrow board (for example, see Patent Documents 1 to 5) is also known.

[0004] However, since the above-mentioned conventional support leg for a barricade has a configuration in which a light reflecting material is attached to the flat surface portion of the support leg, there are cases where it is difficult to notice the reflected light from the driver's seat depending on the angle at which the light of the automobile headlamp hits (for example, when the distance between the automobile and the barricade is far, it is easy to notice from the driver's seat, but when the distance between the automobile and the barricade approaches, it becomes difficult to notice, etc.).

[0006] The present invention aims to solve the problems of the prior art described above, and in summary, it provides a support leg for a barricade that can guide automobile traffic and allows the driver to easily notice the reflected light even when the distance or position between the automobile and the barricade changes. [Means for solving the problem]

[0007] As a means of solving the above problems, the present inventor has provided a support leg for a plastic barricade used by spanning a bar material P, wherein the support leg body 1 includes an upper head 11 to which the bar material P can be attached and detached, and a body 12 formed below the head 11, and a V-shaped recessed groove 12a is formed in the body 12 in which an upper half-line U and a lower half-line D intersect at a predetermined angle when viewed from the front, and a light-reflecting material can be attached to the bottom surface of the recessed groove 12a, and the bottom surface of the recessed groove 12a is formed as a bent surface in the short direction of the groove.

[0008] Furthermore, in this invention, the bottom surface of the groove 12a is composed of a first bottom surface F facing forward formed on the inside of the V-shape and a second bottom surface L facing left or right formed on the outside of the V-shape, and the first bottom surface F and the second bottom surface L can form a bent surface in the short direction of the groove. As a result, when the distance between the car and the barricade is far, the light reflecting material facing forward can reflect light, and when the distance between the car and the barricade is close, the light reflecting material facing left or right can reflect light in an oblique direction.

[0009] Furthermore, in this invention, the bottom surface of the groove 12a is inclined downward or upward in the longitudinal direction of the upper half-line U and the lower half-line D grooves such that the apex T of the V-shape is the deepest or shallowest point. This makes it easier to reflect the light upward towards the driver's seat of the vehicle, even when the distance between the vehicle and the barricade is close and light is incident downward, thus providing an excellent vehicle guidance effect.

[0010] Furthermore, by forming a pair of recessed grooves 12a symmetrically on the body portion 12 and extending across the entire upper and lower portion of the body portion 12, and by forming a window portion W between the pair of recessed grooves 12a, it can be used for either right-side or left-side guidance, and by keeping the area of ​​the body portion 12 small, the weight of the barricade support legs can be reduced.

[0011] Furthermore, in this invention, by forming grooves 12 of the same shape on the front and back surfaces of the body portion 12 in opposing positions, the orientation of the front and back can be changed, allowing it to be used for either right-side guidance or left-side guidance. [Effects of the Invention]

[0012] The support leg for the barricade of the present invention is configured to have a V-shaped groove formed on the body, to which a light-reflecting material can be attached to the bottom surface of the groove, and the bottom surface of the groove is formed as a curved surface in the short direction of the groove. As a result, even when the distance between the vehicle and the barricade changes and the relative positions of the headlights, driver's seat and barricade change, the groove reflects light from surfaces with different angles, making it easier to reflect light back to the driver's seat, thus making it easier for the driver to notice the reflected light.

[0013] Therefore, when driving a car and passing through a construction site, it is easy to notice the barricade's directional signs whether you are far away or close by, and by following the signs and avoiding the construction site, you can pass through safely. [Brief explanation of the drawing]

In the figures, what is indicated by reference numeral 1 is the support leg main body, and what is indicated by reference numeral 2 is the clamp member. Also, what is indicated by reference numeral U is the upper half straight line of the U-shape, and what is indicated by reference numeral D is the lower half straight line of the U-shape. Also, what is indicated by reference numeral F is the first bottom surface, and what is indicated by reference numeral L is the second bottom surface. Also, what is indicated by reference numeral W is the window portion.

[0016] [[ID=ZO]]「Configuration of the Barricade Support Leg」 [1] Regarding the basic configuration The basic configuration of the support leg for a barricade in the present embodiment will be described. In the present embodiment, as shown in FIG. 1, the support leg main body 1 of the plastic support leg for a barricade is constituted by an upper head portion 11 to which a bar material P can be detached, a trunk portion 12 formed below the head portion 11, and a leg portion 13 formed further below the trunk portion 12. Also, clamp members Z are attached to the head portion 11 and the trunk portion 12 of the support leg main body 1 so that the bar material P can be attached. The bar material P is not particularly limited, but generally, a steel pipe (single pipe) or a resin pipe that is used by spanning over the support leg for a barricade can be preferably used.

[0017] It should be noted that there seems to be an error in the original text where "符号Z" is used instead of "符号2" in the description of attaching the clamp member in line . The above translation has been corrected accordingly.Further, on the body portion 12 of the support leg body 1, a U-shaped concave groove portion 12a is formed in which the upper half straight line U and the lower half straight line D intersect at a predetermined angle in the front view of FIG. 1, and a light reflecting material S such as a light reflecting sheet is attachable to the bottom surface of the concave groove portion 12a as shown in FIG. 2. Also, by making the bottom surface of the concave groove portion 12a a curved surface in the short side direction of the groove (the direction orthogonal to the longitudinal direction of the groove) as shown in FIG. 2, even when the distance between the automobile and the support leg for the barricade changes and the relative positions of the headlight, the driver's seat, and the barricade change, light can be reflected toward the driver's seat.

[0018] [2] Regarding the support leg body [2-1] Material of the support leg body Next, the support leg body 1 will be described in detail. Regarding the material of the support leg body 1, in this embodiment, high-density polyethylene (HDPE) is adopted, but other resins can be used as long as they are thermoplastic resins having a predetermined strength. For example, ABS resin, polypropylene, etc. can also be adopted. Also, in this embodiment, a hollow blow molded product is adopted for the support leg body 1, but a solid one or an injection molded product can also be adopted.

[0019] [2-2] Shape of the head Regarding the shape of the head 11 of the support leg body 1, in this embodiment, in the front view shown in FIG. 1, it has a cavity portion 11a in the center and is provided with a mounting bar portion 11b on the cavity portion 11a. Then, by inserting the clamp member 2 into the cavity portion 11a and fixing it to the mounting bar portion 11b, the clamp member 2 is attached to the head 11 of the support leg body 1. The shapes of the head 11, the cavity portion 11a, and the mounting bar portion 11b are not limited to this and can be appropriately changed according to the type of the clamp member 2.

[0020] [2-3] Shape of the body portion Regarding the shape of the body 12 of the support leg body 1 described above, in this embodiment, as shown in Figure 1 when viewed from the front, it has an A-shape with a large window W in the center and diagonal support columns on the left and right sides. The left and right support columns each have a V-shaped recessed groove 12a formed along their entire length. In this embodiment, as shown in Figure 1 when viewed from the front, a cavity 12b is formed in the lower center, and a mounting bar 12c is provided on the cavity 12b. The clamp member 2 for attaching the bar material P is inserted into the cavity 12b and fixed to the mounting bar 12c, thereby attaching the clamp member 2 to the body 12 of the support leg body 1. Note that the shapes of the cavity 12b and the mounting bar 12c are not limited to these and can be appropriately changed depending on the type of clamp member 2.

[0021] Regarding the groove portion 12a described above, in this embodiment, as shown in Figure 2, the bottom surface of the groove portion 12a is composed of a first bottom surface F facing forward formed on the inside of the V-shape and a second bottom surface L facing left or right formed on the outside of the V-shape, and the first bottom surface F and the second bottom surface L form a bent surface in the short direction of the groove. As a result, when a light-reflecting material S is attached to the bottom of the groove portion 12a, it is possible to reflect light forward when the distance between the car and the barricade is far, and to reflect light diagonally to the left or right when the distance between the car and the barricade is close.

[0022] The angle between the first bottom surface F and the second bottom surface L of the groove 12a is not particularly limited, but it is preferably within the range of 150 to 175 degrees. The first bottom surface F and the second bottom surface L of the groove 12a can also be formed in a curved shape, and the second bottom surface L can be composed of multiple surfaces with gradually different inclines. In this embodiment, the curved surface consisting of the first bottom surface F and the second bottom surface L is convex, but it can also be formed concave. The depth of the groove 12a can also be appropriately changed according to the thickness of the light-reflective sheet or other light-reflective material (e.g., light-reflective paint) used.

[0023] Furthermore, in this embodiment, as shown in Figures 1 and 3, the bottom surface of the groove 12a is inclined downward or upward in the longitudinal direction of each groove, the upper half-line U and the lower half-line D, such that the apex T of the V-shape is the deepest point. Specifically, the grooves are inclined such that the depth of the groove 12a at each end of the upper half-line U and the lower half-line D is smallest, and the depth of the groove 12a at the apex T of the V-shape is largest. This makes it easier to reflect the light upward towards the driver's seat of the vehicle, even when the distance between the vehicle and the barricade is close and light is incident downward, thus providing an excellent vehicle guidance effect.

[0024] The angles of the upper half-line U and lower half-line D of the groove 12a are not particularly limited, but are preferably in the range of 150 to 175 degrees. The upper half-line U and lower half-line D of the groove 12a can also be curved inclined surfaces, and furthermore, the inclined surfaces can be angled in stages from each end of the upper half-line U and lower half-line D toward the apex T of the V-shape. In this embodiment, the grooves of the upper half-line U and lower half-line D are inclined so that the apex T of the V-shape is the deepest part, but they can also be inclined so that the apex T of the V-shape is the shallowest part (the part with the least depth).

[0025] In this embodiment, a pair of recessed grooves 12a are formed symmetrically on the left and right support columns of the body 12, extending across the entire upper and lower portion of the body 12, and a window W is formed between the pair of recessed grooves 12a, allowing the light-reflecting material S to be attached to either the left or right recessed groove 12a. Therefore, the barricade support legs can be used for either right-side or left-side guidance. Furthermore, by providing the window W, the area of ​​the body 12 in the front view in Figure 1 can be reduced, thus allowing the barricade support legs to be made lighter. In this embodiment, weight reduction is further achieved by providing weight-reducing cutouts 12d on the lower left and right portions of the body 12.

[0026] In this embodiment, as shown in Figure 4, identical grooves 12 and 12' are formed on the front and back surfaces (front and back) of the body portion 12 at opposing positions. This allows the vehicle to be used for either right-side or left-side guidance by changing the orientation of the front and back surfaces. In this embodiment, the grooves 12a on the front and back surfaces are identical in shape, but it is also possible to use grooves 12a with different bottom shapes on the front and back surfaces. In this embodiment, symmetrical, V-shaped grooves 12 are formed, but it is also possible to use a V-shaped groove 12a on only one side (left or right).

[0027] [2-4] Leg shape Regarding the shape of the legs 13 of the support leg body 1 described above, as shown in Figures 1 and 4, in this embodiment, legs 13 are formed on both the left and right sides. The size, arrangement, and number of legs 13 can be appropriately changed depending on the shape of the body 12. It is also possible to adopt a support leg body 1 shape without legs 13. In this embodiment, as shown in Figure 4, a protruding wear portion 13a is formed on the bottom surface of the legs 13 to prevent the main body of the legs 13 from being worn down even when the barricade support legs are dragged and carried. Regarding the shape of this wear portion 13a, in this embodiment it is formed in a wave-like linear shape, but it can also be formed in a dotted or multi-row shape.

[0028] [2-5] Overall shape of the support screen body In this embodiment, the support leg body 1 is shaped like type A in a front view as shown in Figure 1, but the overall shape is not limited to this. For example, a flat plate shape without a window portion, as shown in Japanese Patent Application Publication No. 2001-90034, can be adopted, as can an arrow-shaped shape, as shown in Japanese Patent Application Publication No. 2006-144314. Furthermore, when adopting a flat plate or arrow-shaped shape, multiple V-shaped recessed groove portions 12a facing the same direction can be formed side by side.

[0029] [3] About light-reflective materials Regarding the light-reflecting material S described above, in this embodiment, a light-reflecting sheet is used that is attached to the entire bottom surface of the groove 12a, but a light-reflecting paint can also be applied to the bottom surface of the groove 12a. In addition, the light-reflecting sheet can be insert-molded, or the light-reflecting sheet or light-reflecting paint can be attached or applied only to the groove 12a rather than to the entire surface.
