Summary of the Invention

Problems to be Solved by the Invention

[0005] However, safety cones cannot be folded and stored flat side by side, and even when stacked on top of each other, they cannot be stacked high, taking up a large amount of storage space. Also, guardrails, especially those called single-pipe barricades, often have A-shaped synthetic resin integral stands on both sides, which cause bulkiness during storage and transportation. Also, when used in factories or near the coast, there are problems such as lack of durability and weather resistance.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a regulating stand that can be folded during transportation and storage, and a regulating stand with excellent durability.

Means for Solving the Problems

[0007] In order to solve the above problems, the regulating stand according to the present invention includes a stand body composed of a top portion and a first leg portion, a second leg portion hinge-coupled to an end of the top portion, and at a vicinity of the lower ends of both leg portions, one end is hinge-coupled to a hinge support member attached to the first leg portion so as to face the second leg portion, and the other end is lockable to the second leg portion, and a connecting member that holds both leg portions in an open-leg posture during assembly and use in a state where the other end is locked to the second leg portion. Clamp portions for detachably holding a regulating horizontal member are respectively attached to the upper surface of the top portion and the upper surface of the connecting member. The top portion, the first leg portion, and the second leg portion that constitute the stand body are each composed of a member having a U-shaped cross section with a concave inner side, the connecting member is composed of a member having a U-shaped cross section with a concave lower side, and an outer width dimension of the connecting member is equal to or less than an inner width dimension of the second leg portion. The connecting member rotates around a hinge so that the other end of the connecting member faces upward from an open-leg posture during assembly and use of both leg portions, and can be stored between both leg portions in a closed-leg posture of both leg portions. When the connecting member moves from a closed-leg posture to an open-leg posture of both leg portions, the connecting member rotates around a hinge so that the other end of the connecting member faces downward, and at an open-leg posture during assembly and use of both leg portions, a locking recess formed on the lower surface of the other end of the connecting member is locked from above to a locking shaft attached and supported near the lower end of the inner surface of the U-shaped cross section of the second leg portion.

Effects of the Invention

[0008] As described above, according to the restricting stand of the present invention, during storage and transportation, both legs can be folded into the closed-leg position, and the connecting part can be stored inside both legs, so that it can be stored and transported in a compact state. During use, the folded legs can be opened, the connecting member can be locked, and the horizontal member can be held by the upper and lower clamping parts, achieving the excellent effect of being easily assembled into the open-leg position.

Best Mode for Carrying Out the Invention

[0010] The best mode for carrying out the present invention will be described with reference to the drawings. FIGS. 1 to 6 show an embodiment of the present invention. In the figures, reference numeral S indicates the restricting stand.

[0011] As shown in FIGS. 1 and 2, the stand S is composed of a stand body 1 including a top 2 and a first leg 3, a second leg 4 hinged to an end 2a of the top 2, and a connecting member 5 having one end 5a hinged to the first leg 3 and capable of being locked to the inner surface of the second leg 4.

[0012] The stand body 1 is composed of a top portion 2 that extends horizontally in the front-rear direction and a first leg portion 3 that extends obliquely downward from an end portion 2b of the top portion 2. The top portion 2 and the first leg portion 3 are each made of a stainless steel member having a U-shaped cross-section with a downward (inward) concave cross-sectional shape, and the upper end of the first leg portion 3 is fixed to the end portion 2b of the top portion 2 by welding.

[0013] The second leg portion 4 has the same length as the first leg portion 3, is made of a stainless steel member having a U-shaped cross-section with an inward concave cross-sectional shape, and is rotatably supported at an end portion 2a of the top portion 2 via a hinge portion 6.

[0014] The connecting member 5 is supported such that its base end portion 5a can rotate upward via a hinge portion 8 with respect to a hinge support member 7 attached and supported in a horizontal posture near the lower end portion of the inner surface of the first leg portion 3. A locking recess 9 formed on the lower surface of the free end 5b of the connecting member 5 can be locked from above with respect to a locking shaft 10 attached and supported near the lower end portion of the inner surface of the second leg portion 4. The stand S in the open-leg posture with the locking recess 9 of the free end 5b of the connecting member 5 locked to the locking shaft 10 has an A-shaped shape as a whole when viewed from the front.

[0015] A first clamp portion 11 for detachably holding a regulating horizontal member 20 is attached to the upper surface of the top portion 2 of the stand body 1. A second clamp portion 12 for detachably holding the same regulating horizontal member 20 is attached to the upper surface of the connecting member 5.

[0016] The first clamp portion 11 and the second clamp portion 12 are each composed of a clamp body 13 and a clamp piece 14. The clamp body 13 is fixed to the upper surfaces of the top portion 2 and the connecting member 5 respectively by bolts and nuts (not shown), and the upper clamp piece 14 is hingedly coupled to the lower clamp body 13 so as to be rotatable. The first clamp portion 11 and the second clamp portion 12 are both made of stainless steel, but iron can also be used.

[0017] The above-mentioned first clamp part 11 and second clamp part 12, with the upper clamp piece 14 open, place the end of the horizontal member 20 inside the lower clamp body 13, close the upper clamp piece 14, and fasten the clamp body 13 and the clamp piece 14 together with bolts 15 and nuts 16, thereby firmly fixing and supporting the horizontal member 20.

[0018] The horizontal member 20 uses a steel pipe, but stainless steel or iron members can also be used. Instead of the steel pipe, a protective fence that can be supported by the first clamp part 11 and the second clamp part 12 may be installed.

[0019] For the regulating stand S with the above structure, from the posture during assembly and use shown in Fig. 2 (in the A-shaped open-leg posture), as shown in Fig. 3, by rotating the connecting member 5 counterclockwise (in the direction of arrow A) around the hinge part 8, the free end 5b of the connecting member 5 slides upward along the inner surface of the second leg part 4. During this process, the second leg part 4 opens with respect to the first leg part 3. However, if the connecting member 5 is further rotated counterclockwise (in the direction of arrow A) around the hinge part 8, the second leg part 4 can be rotated in the direction of closing with respect to the first leg part 3. As a result, as shown in Fig. 4, the second leg part 4 becomes substantially parallel to the first leg part 3, and the posture during storage can be changed to a closed-leg posture where the connecting member 5 is housed inside the second leg part 4.

[0020] Next, the usage method of the regulating stand S configured as above will be described below with reference to the drawings.

[0021] First, transport the required number of stands S and horizontal members 20 stored in a horizontal posture in the warehouse to the site. Fig. 6 shows the stand S stored in a horizontal posture and arranged in the warehouse. As shown in the figure, the stand S is stored in a state where the first and second leg parts 3, 4 and the connecting member 5 are compactly folded.

[0022] As described above, in the stand S in a state where the first and second legs 3 and 4 and the connecting member 5 are compactly folded, as shown in FIGS. 3 to 4, the connecting member 5 is rotated upward around the hinge portion 8, and then the second leg 4 is rotated downward around the hinge portion 6. By doing so, with the connecting member 5 almost completely housed in the concave connecting member housing portion 17 formed on the inner surface side of the second leg 4, the second leg 4 can be closed to a closed leg posture substantially parallel to the first leg 3.

[0023] The administrator can efficiently store a large number of stands S in a compactly folded state in the warehouse together with the horizontal member 20.

[0024] Next, when the folded stand S is transported from the warehouse to the site of regulation together with the horizontal member 20 in the required number, it is unloaded from the cargo compartment and the barricade is assembled. Regarding the stand S in the folded state, as shown in FIG. 3, when the second leg 4 is rotated in the leg-opening direction around the hinge portion 6 with respect to the first leg 3, the second leg 4 opens with respect to the first leg 3, and at the same time, the connecting member 5 rotates downward around the hinge portion 8 (in the direction of arrow B), and the free end 5b of the connecting member 5 slides downward in the connecting member housing portion 14 (in the direction of arrow B), and the locking concave portion 9 of the free end 5b of the connecting member 5 is locked to the locking shaft 10 from above as it is. Thereby, the stand S becomes the leg-opening posture during assembly and use shown in FIG. 2(A).

[0025] When the stand S is in the leg-opening posture during assembly and use shown in FIG. 2(A), the remaining stands S are also changed from the folded state to the posture during assembly and use in the same procedure. As shown in FIGS. 5 and 1, two horizontal members 20 are attached vertically between these pair of stands S, S. One end portion of the horizontal member 20 is disposed at the upper and lower open first and second clamp portions 11 and 12 of the stand S, the clamp piece 14 is closed from above, and it is tightened with the clamp body 13 by bolts 15 and nuts 16. This is also disposed and attached to the other end portion of the horizontal member 20 with respect to another stand S.

[0026] In this way, after finishing the assembly of the barricade composed of a pair of stands S, S and two horizontal members 20, 20, the remaining barricades are sequentially assembled. The assembled barricades can be used alone or in combination for regulation in the factory site or passageway, and for safety measures at the construction site (such as manhole construction).

[0027] According to the stand S of this embodiment, during storage and transportation, as shown in FIG. 4, both leg portions (the first leg portion 3 and the second leg portion 4) are folded in the closed leg posture, and the connecting portion 5 is stored in the connecting portion storage portion 17 inside one leg portion (the second leg portion 4), and can be stored and transported in a compact state as shown in FIG. 6.

[0028] Also, according to the stand S of this embodiment, during use, the folded leg portions (the first leg portion 3 and the second leg portion 4) are opened, and at the same time, the connecting member 5 is locked to the locking shaft 10 to maintain the open leg posture. Then, the horizontal member 20 is held by the upper and lower clamp portions (the first clamp portion 11 and the second clamp portion 12), and the barricade can be easily assembled.

[0029] As shown in FIG. 5, a display 19 including a bulletin 18 for attracting the attention of pedestrians and passers-by can be suspended from the horizontal member 20 between the stands S, S.

[0030] According to the stand S of this embodiment, since all the constituent members (the stand body 1, the second leg portion 4, the connecting member 5, the first and second clamp portions 11, 12) are made of stainless steel, they are superior in durability and weather resistance compared to those made of synthetic resin used in conventional stands. Therefore, it is suitable for regulation within the factory facilities, for regulation in areas where gas is likely to occur such as volcanic regions, and for ensuring safety in places such as coastal areas (e.g., quay wall construction) where salt damage is likely to occur.

[0031] Thus, according to the regulating stand of the present invention, a regulating stand that can be installed outdoors or indoors, is excellent in durability and weather resistance during use, and can be folded compactly during storage and transportation has been realized.

Industrial Applicability

[0032] The regulating stand according to the present invention can be temporarily installed outdoors or indoors and is widely applicable as a tool for demarcating a restricted area such as prohibiting entry, prohibiting access, and ensuring safety.
