In FIG. 1, the barricade 100 is formed by two barricade components 1 which are installed apart from each other in the horizontal direction X in order to support two single pipes 10 which are separated from each other in the vertical direction Y in the horizontal direction X. It is composed. The barricade structure 1 includes a main body 2 and a cap portion 3 formed of a separate body that can be attached to and detached from the main body 2.

As shown in FIG. 2, the main body 2 has a first insertion portion 21 formed so as to penetrate in the horizontal direction X, and a first female screw surface 22 formed on the inner peripheral surface of the first insertion portion 21. .. Further, the first insertion portion 21 and the first female screw surface 22 are formed at two positions separated from each other in the vertical direction Y of the main body 2. Further, the main body 2 is provided with an arrow 23 in the rotation direction when the cap portion 3 is inserted on the upper surface of the portion where the first insertion portion 21 on the one end side X1 is formed. On the other hand, the arrow is not provided on the other end side X2 of the main body 2.

Therefore, using the arrow 23 as a mark, the side of the main body 2 into which the cap portion 3 is inserted (one end side X1) and the direction in which the cap portion 3 is screwed can be easily determined, so that workability is improved. It should be noted that the arrow 23 can be considered in various installation examples such as when it is printed directly on the main body 2, when it is attached to the main body 2 with a sticker or the like, or when it is integrally formed during blow molding of the main body 2. Be done. Further, it goes without saying that the same can be performed with anything other than the arrow 23 as long as it serves as a mark for the main body 2, for example, a pattern is applied to one end side X1 of the main body 2, and the color is colored. Various examples can be considered.

As shown in FIG. 3, the main body 2 is integrally formed with a first insertion portion 21 and a first female screw surface 22 in a hollow shape by blow molding, which is an inexpensive manufacturing method, using a resin material, for example, polyethylene. NS. The first insertion portion 21 of the main body 2 is formed in a tapered shape in which the inner diameter becomes smaller from the one end side X1 to the other end side X2. That is, the inner diameter W1 of one end side X1 of the first insertion portion 21 is formed larger than the inner diameter W2 of the other end side X2.

As shown in FIG. 4, the cap portion 3 includes a tubular portion 31, a second insertion portion 32 formed so that one end of a single pipe 10 can be inserted in the horizontal direction X of the tubular portion 31, and a tubular portion. The outer peripheral surface of 31 has a first male threaded surface 33 screwed into the first female threaded surface 22 of the first insertion portion 21. Therefore, the inner diameter W5 of the second insertion portion 32 is formed to be the same as or slightly larger than the outer diameter W6 of the single pipe 10 (see FIG. 5C). The cap portion 3 has three or more slit portions 34 extending in the horizontal direction X from the other end side X2 end to the one end side X1 in the cylindrical portion 31 at equal intervals in the circumferential direction, and here at equal intervals in the circumferential direction. It is formed in 4 places.

A closed wall 310 is formed on one end side X1 of the tubular portion 31. Further, a knob portion 35 projecting from one end side X1 of the closing wall 310 is provided. Then, the knob portion 35 is formed with a through hole 36 in a direction perpendicular to the horizontal direction X. The size of the knob portion 35 is formed so that it can be inserted into the second insertion portion 32 of the cap portion 3.

The inner diameter W2 (see FIG. 3) of the other end side X2 of the first insertion portion 21 of the main body 2 is formed to be smaller than the outer diameter W4 (see FIG. 4) of the other end side X2 of the tubular portion 31 of the cap portion 3. NS. The inner diameter W1 (see FIG. 3) of one end side X1 of the first insertion portion 21 of the main body 2 is formed to be larger than the outer diameter W4 of one end side X1 of the tubular portion 31 of the cap portion 3. Therefore, the tubular portion 31 of the cap portion 3 can be attached to and detached from the first insertion portion 21 of the main body 2.

Further, the outer diameter W4 of the other end side X2 of the cap portion 3 is formed to be smaller than the outer diameter W3 of the one end side X1. The cap portion 3 is formed of a resin material having higher strength than the resin material of the main body 2, for example, a prepropylene containing glass fiber. An example in which the relationship between one end side X1 and the other end side X2 of the outer diameter of the tubular portion 31 of the cap portion 3 is formed such that the outer diameter W4 of the other end side X2 is smaller than the outer diameter W3 of the one end side X1. However, the present invention is not limited to this, and it is conceivable that the outer diameter of the tubular portion 31 of the cap portion 3 is formed to be the same from one end side X1 to the other end side X2. It is also conceivable that the outer diameter of the tubular portion 31 of the cap portion 3 is formed so that the outer diameter W3 of the one end side X1 is smaller than the outer diameter W4 of the other end side X2. However, considering the ease of attaching and detaching the main body 2 of the cap portion 3 to the first insertion portion 21, the outer diameter W4 of the other end side X2 of the cap portion 3 is formed to be smaller than the outer diameter W3 of the one end side X1. Is desirable.

Then, as shown in FIG. 5C, with one end of the single pipe 10 inserted into the second insertion portion 32 of the tubular portion 31 of the cap portion 3, the first female screw surface of the first insertion portion 21 of the main body 2 is inserted. The first male threaded surface 33 of the tubular portion 31 of the cap portion 3 can be screwed into the 22.

A method of installing the barricade 100 using the barricade structure 1 of the first embodiment configured as described above will be described with reference to FIGS. 5A and 5B. First, the two main bodies 2 are arranged at positions separated from each other in the horizontal direction X. At this time, the direction of the main body 2 is determined with the arrows 23 described on the main body 2 facing each other. Next, one end of the single pipe 10 is inserted from the other end side X2 of the first insertion portion 21 of the main body 2 and protrudes from the one end side X1 of the first insertion portion 21 of the main body 2 (FIG. 5A).

Next, one end of the single pipe 10 is inserted into the second insertion portion 32 of the cap portion 3 (FIG. 5B). Next, with the single pipe 10 inserted in the second insertion portion 32 of the cap portion 3, the operator grasps the knob portion 35 of the cap portion 3 with one hand and first of the main body 2. It is inserted into the insertion portion 21 from one end side X1 and rotated with the direction of the arrow 23 as a mark. Then, the first male screw surface 33 of the cylindrical portion 31 of the cap portion 3 is screwed into the first female screw surface 22 of the first insertion portion 21 of the main body 2 (FIG. 5C). At this time, while grasping the side of the single pipe 10 from the other end side X2 of the first insertion portion 21 with the other hand of the operator, or rotating the cap portion 3 in the direction opposite to the rotation direction. If this is done, the cap portion 3 can be easily and surely screwed into the first insertion portion 21.

Here, the first insertion portion 21 of the main body 2 is formed in a tapered shape in which the inner diameter becomes smaller toward the other end side X2 from the one end side X1, and further, the other end side X2 of the first insertion portion 21 of the main body 2 is formed. Since the inner diameter W2 of the cap portion 3 is formed smaller than the outer diameter W4 of the other end side X2 of the cap portion 3, the cap portion 3 is directed from one end side X1 of the first insertion portion 21 of the main body 2 toward the other end side X2. The more it is screwed, the more it will be tightened. Therefore, one end of the single pipe 10 in the second insertion portion 32 of the cap portion 3 can be securely fixed by using the cap portion 3 at the position of the first insertion portion 21 of the main body 2.

Further, in the screw insertion of the cap portion 3, since the slit portion 34 exists in the cylindrical portion 31 of the cap portion 3, the tubular portion 31 of the cap portion 3 collapses in the central axis Q direction, and the cylinder of the cap portion 3 The width of the slit portion 34 of the shape portion 31 in the circumferential direction is reduced. Thereby, the tightening can be performed more reliably. Therefore, the single pipe 10 in the second insertion portion 32 of the cap portion 3 is more securely fixed by the tubular portion 31 of the cap portion 3.

Then, the other end of the single pipe 10 and all other parts are also performed in the same manner, and when the single pipe 10 is installed on the main body 2 by using the cap portion 3, the barricade configuration 1 is configured as shown in FIG. The barricade 100 can be installed.

When the cap portion 3 is attached to the main body 2 and the operator's force is insufficient in the operation for tightening the cap portion 3 as shown above, a rod-shaped shape is formed in the through hole 36 of the cap portion 3. A member, for example, a shaft portion of a screwdriver, can be inserted, and the cap portion 3 can be rotated and tightened according to the "lever principle".

Then, when the use of the barricade 100 is completed, the single pipe 10 is removed from the barricade structure 1 and disassembled. In this case, the operation opposite to the previous operation, the knob portion 35 is gripped, the cap portion 3 is rotated in the direction opposite to the arrow 23, and the cap portion 3 is removed from the main body 2. However, since the cap portion 3 is tightened and firmly installed in the first insertion portion 21 of the main body 2, in order to remove the cap portion 3, a rod-shaped member is inserted into the through hole 36 of the knob portion 35. If the cap portion 3 is rotated in the direction opposite to the arrow 23 according to the "leck principle", the cap portion 3 can be easily and easily removed from the main body 2. Then, after the single pipe 10 is removed, only the cap portion 3 is screwed and inserted without inserting the single pipe 10 into the first insertion portion 21 of the main body 2.

Then, the main body 2 into which the cap portion 3 is inserted can be stacked and stored as shown in FIG. This is because the knob portion 35 of the cap portion 3 of one barricade component 1 is inserted into the second insertion portion 32 of the cap portion 3 of the other barricade structure 1 on the stacked upper side. Therefore, since the barricade components 1 can be laminated without gaps when transporting, storing, or moving a plurality of barricade components 1, the required volume can be reduced. Further, since the knob portion 35 is inserted into the second insertion portion 32 of the cap portion 3, it is possible to prevent the load collapse of the plurality of stacked barricade components 1. Further, since the main body 2 can be transported, stored, and moved while being attached to the cap portion 3, the barricade configuration 1 can be handled without losing the cap portion 3.

In the first embodiment, an example in which the first insertion portion 21 and the first female screw surface 22 are integrally molded by blow molding the main body 2 is shown, but the present invention is not limited to this, and for example, FIG. 7 shows. As shown, it is also conceivable to form the first insertion portion 21 and the first female screw surface 22 separately from the main body 2. In that case, the first insertion portion 21 and the first female screw surface 22 can be formed of a material different from that of the main body 2, and is more durable than the material of the main body 2 which is the same as the cap portion 3, for example. For example, it is conceivable to form it with polypropylene containing glass fiber. Then, if the first insertion portion 21 is fixed to the main body 2 in advance by adhesion or the like, it can be used in the same manner as in the first embodiment.

Further, in the first embodiment, an example is shown in which the slit portions 34 are formed in the cap portion 3 at four locations separated from each other in the circumferential direction, but the present invention is not limited to this, and the slit portions 34 are equal in the circumferential direction. If three or more pieces are formed apart from each other at intervals, it is easy to fall down in the direction of the central axis, and the same effect can be obtained. Further, the larger the number of slit portions 34, the easier it is for the collapse to occur. Therefore, it is desirable to form the number of slit portions 3 to such an extent that the durability of the cap portions 3 can be ensured.

Further, in the first embodiment, an example in which two single pipes 10 are used is shown, but the present invention is not limited to this, and if three single pipes 10 are used, the main body 2 is supported. It is also possible to appropriately form the first insertion portion 21 at the location where the first insertion portion is to be formed and to install the first insertion portion 21 by using the cap portion 3 as in the first embodiment.

Further, the external shape of the main body 2 is not limited to the one shown in FIG. 2, and other shapes such as a character shape or an animal shape can be formed in the same manner.

Embodiment 2.
In the first embodiment, an example in which the cap portion has a first male screw surface is shown, but the present invention is not limited to this, and an example in which the cap portion has a second female screw surface will be described. FIG. 8 is a diagram showing a partial configuration of the barricade structure according to the second embodiment. 9A is a side view showing the configuration of the insert body of the barricade structure shown in FIG. 8, and FIG. 9B is a side view showing the structure of the cap portion of the barricade structure shown in FIG. 10A is a right side view showing the configuration of the main body of the barricade configuration shown in FIG. 8, and FIG. 10B is a left side view showing the configuration of the main body of the barricade configuration shown in FIG. 11A, 11B and 11C are diagrams showing the installation process of the barricade component shown in FIG.

In each figure, the same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 8, the barricade component 1 of the second embodiment is composed of a main body 2, an insert body 4, and a cap portion 3. The main body 2 is formed so that the first insertion portion 210 penetrates in the horizontal direction X. The insert body 4 is formed as a separate body that can be attached to and detached from the first insertion portion 210 of the main body 2. The cap portion 3 is formed separately from the first insertion portion 210 of the main body 2 and the main body 2 that can be attached to and detached from the insertion body 4. Then, the insertion body 4 is inserted from the other end side X2 of the first insertion portion 210 of the main body 2.

The insertion body 4 includes a third insertion portion 41 formed so that one end of the single pipe 10 can be inserted in the horizontal direction X, a second male screw surface 42 formed on the outer peripheral surface of the third insertion portion 41, and the like. It has at least one stop portion 43 (see FIG. 9A) on the outer periphery of the end side X2, here at two locations 180 degrees apart in the circumferential direction. Therefore, the inner diameter W9 of the third insertion portion 41 is formed to be the same as or slightly larger than the outer diameter W6 of the single pipe 10 (see FIG. 11C).

The outer diameter of the third insertion portion 41 of the insertion body 4 is such that the outer diameter W18 of the one end side X1 is smaller than the outer diameter W8 of the other end side X2. Further, the outer diameter of the third insertion portion 41 of the insertion body 4, that is, the outer diameter W8 of the other end side X2 and the outer diameter W18 of the one end side X1 is formed to be smaller than the inner diameter W7 of the first insertion portion 210 of the main body 2. Will be done. Therefore, the third insertion portion 41 of the insertion body 4 can be attached to and detached from the first insertion portion 210 of the main body 2. In the insert body 4, there are three or more slit portions 44 extending in the horizontal direction X from one end side X1 end to the other end side X2 at equal intervals in the circumferential direction, and here at four locations evenly spaced in the circumferential direction. Is formed in. The insert 4 is formed of a resin material having higher strength than the resin material of the main body 2, for example, a prepropylene containing glass fiber.

Although the outer diameter of the third insertion portion 41 of the insert body 4 is formed so that the outer diameter W18 of the one end side X1 is smaller than the outer diameter W8 of the other end side X2, the outer diameter is not limited to this. It is also conceivable that the outer diameter of the third insertion portion 41 of the insertion body 4 is formed to be the same from one end side X1 to the other end side X2. It is also conceivable that the outer diameter of the third insertion portion 41 of the insertion body 4 is formed so that the outer diameter W3 of the one end side X1 is larger than the outer diameter W4 of the other end side X2. However, considering the ease of attaching the main body 2 of the insertion body 4 to the first insertion portion 210 and the ease of attaching the cap portion 3 to the insertion body 4, the third insertion portion 41 of the insertion body 4 It is desirable that the outer diameter W18 of the one end side X1 is smaller than the outer diameter W8 of the other end side X2.

The cap portion 3 is formed in a tubular portion 37 having the same inner diameter W7 as the inner diameter W7 of the first insertion portion 210 or having a small outer diameter W10, and in the tubular portion 37 so that the insert body 4 can be inserted in the horizontal direction X. On the inner peripheral surface of the second insertion portion 38, the second female screw surface 39 screwed onto the second male thread surface 42 of the insert body 4, and the outer circumference of the one end side X1 of the tubular portion 37. It has a flange portion 311 (see FIG. 9B) having an outer diameter W11 formed larger than the inner diameter W7 of the first insertion portion 210 while projecting to the outer peripheral side. Therefore, the tubular portion 37 of the cap portion 3 can be attached to and detached from the first insertion portion 210 of the main body 2.

The tubular portion 37 is formed in a tapered shape in which the inner diameter of the second insertion portion 38 decreases from the other end side X2 toward the one end side X1. That is, the inner diameter W12 of the other end side X2 of the second insertion portion 38 is formed larger than the inner diameter W13 of the one end side X1. Further, the inner diameter W13 of one end side X1 of the second insertion portion 38 of the tubular portion 37 is formed to be smaller than the outer diameter W18 of one end side X1 of the insertion body 4. Further, the inner diameter W12 of the other end side X2 of the second insertion portion 38 of the tubular portion 37 is formed to be larger than the outer diameter W18 of the one end side X1 of the insertion body 4. The main body 2 has a first recess 211 (see FIG. 10A) that engages with the stopper 43 of the insertion body 4 at the other end side X2 of the first insertion portion 210, and a cap portion 3 at one end side X1 of the first insertion portion 210. It has a second recess 212 (see FIG. 10B) that engages with the collar portion 311 of the.

Then, as shown in FIG. 11C, with one end of the single pipe 10 inserted into the third insertion portion 41 of the insertion body 4, the insertion body 4 is inserted into the first insertion portion 210 of the main body 2 from the other end side X2. It is inserted, inserted into the first insertion portion 210 of the main body 2, the stop portion 43 is engaged with the first recess 211, and the tubular portion 37 of the cap portion 3 is seconded to the second male screw surface 42 of the insertion body 4. The female screw surface 39 can be screwed and inserted. Further, the flange portion 311 of the cap portion 3 is engaged with the second recess 212 of the main body 2.

A method of installing the barricade 100 using the barricade structure 1 of the second embodiment configured as described above will be described with reference to FIGS. 11A to 11C. In addition, the part different from the above-described first embodiment will be mainly described. One end of the single pipe 10 is inserted into the third insertion portion 41 of the insertion body 4 (FIG. 11A). Then, with the single pipe 10 inserted into the third insertion portion 41 of the insertion body 4, the insertion body 4 is inserted into the first insertion portion 210 of the main body 2 from the other end side X2.

Then, the stop portion 43 of the insertion body 4 is engaged with the first recess 211 of the main body 2 (FIG. 11B). The process is not limited to the steps of FIGS. 11A and 11B. For example, after engaging the stop portion 43 of the insert body 4 with the first recess 211 of the main body 2, the third insertion portion 41 of the insert body 4 is engaged. A single pipe 10 may be inserted therein to be in the state shown in FIG. 11B.

Next, with the single pipe 10 inserted into the third insertion portion 41 of the insertion body 4, the operator grasps the knob portion 35 of the cap portion 3 with one hand and first of the main body 2. It is screwed into the insertion portion 210. The second female screw surface 39 of the tubular portion 37 of the cap portion 3 is screwed into the second male screw surface 42 of the insertion body 4 inserted into the first insertion portion 210 of the main body 2 (FIG. 11C).

The second insertion portion 38 of the cap portion 3 is formed in a tapered shape in which the inner diameter becomes smaller from the other end side X2 toward the one end side X1, and further, the second insertion portion 38 on the one end side of the tubular portion 37. Since the inner diameter of the insert body 4 is smaller than the outer diameter W8 of the one end side X1 of the insert body 4, the insert body 4 inserted into the first insertion portion 210 of the main body 2 is formed from the one end side X1 by the cap portion 3. The more it is screwed toward the other end side X2, the more it is tightened. Therefore, one end of the single pipe 10 in the third insertion portion 41 of the insertion body 4 can be securely fixed by using the cap portion 3 at the position of the first insertion portion 210 of the main body 2.

Further, in the screw insertion of the cap portion 3, since the slit portion 44 exists in the insertion body 4, the insertion body 4 collapses in the central axis Q direction, and the width of the slit portion 44 of the insertion body 4 in the circumferential direction is reduced. .. Thereby, the tightening can be surely performed. Then, the single pipe 10 in the third insertion portion 41 of the insertion body 4 is more securely fixed by the insertion body 4. Further, when installed in this way, the stopper 43 of the insertion body 4 is engaged with the first recess 211 of the main body 2 to prevent the insertion body 4 from coming off to the one end side X1. Further, since the flange portion 311 of the cap portion 3 is engaged with the second recess 212 of the main body 2, it is prevented from coming off to the other end side X2.

Since the outer diameter W11 of the collar portion 311 of the cap portion 3 is formed to be larger than the inner diameter W7 of the first insertion portion 210 of the main body 2, the collar portion 212 is not engaged with the second recess 212. It is possible to prevent the portion 311 from coming into contact with the main body 2 and coming off to the other end side X2.
