<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIGS. 1 and 2 are diagrams showing the overall configuration of an interlocking fence. FIGS. 3 to 6 are diagrams showing the configuration of joint members that constitute the interlocking fence.

The interlocking fence in this embodiment is installed in facilities, event venues, roads, etc. to partition spaces. For example, multiple interlocking fences are used to form an enclosed space or guideway.

FIG. 1 is a diagram showing the overall configuration of the interlocking fence, and shows how it is installed on the ground. As shown in this figure, the connected fence has a substantially rectangular outer shape by connecting a plurality of pipe members P in a lattice shape via joint members 1, 2, and 3. Of the sides forming the outer shape of the interlocking fence, two legs F that are in contact with the ground are provided on the lower side that is located below when the interlocking fence is erected.

Here, when the articulated fence in this embodiment is transported or stored as will be described later, the leg portions F are rotated relative to the lower side as shown in FIG. A plurality of interlocking fences are stacked with their surfaces touching in the horizontal direction. In a state in which a plurality of connecting fences are stacked, the joint members 1, 2, and 3 located at the same location of the connecting fences come into contact with each other. For this reason, the interlocking fence in this embodiment is configured so that the joint members 1 and 2 that can come into contact with each other when stacked are in stable contact with each other, as described below.

Note that the connected fence in this embodiment is not necessarily limited to the external shape or lattice shape shown in FIG. It may be formed into any shape. Hereinafter, the configurations of the pipe member P and the joint members 1, 2, and 3 will be mainly described in detail.

The pipe member P is constituted by a substantially cylindrical member having a predetermined length, and its end portion is inserted into the inserted portion provided in the joint members 1, 2, and 3. In this embodiment, a plurality of types of pipe members P with different lengths are prepared, and the pipe members P are arranged at preset locations on the interlocking fence according to their own lengths, and the joint members 1, 2 and 3 are connected.

The joint members 1, 2, and 3 are configured to have a plurality of inserted portions into which the ends of the pipe members P described above are inserted. In this embodiment, a plurality of types of joint members 1, 2, and 3 having different numbers of inserted portions are prepared. For example, the joint members include a first joint member 1 having four inserted parts, a second joint member 2 having two inserted parts, and a third joint member 3 having three inserted parts. There are three types. The structures of the various joint members 1, 2, and 3 will be described in detail below.

First, the configuration of the first joint member 1 will be described with reference to FIGS. 3 and 4. Note that FIG. 3(a) is a diagram of the first joint member 1 viewed from the front side, FIG. 3(b) is a diagram of the first joint member 1 viewed from the back side, and FIG. 3(c) is a diagram of the first joint member 1 as viewed from the back side. It is a view seen from the side. FIG. 4A is a perspective view of the first joint member 1, and FIG. 4B is a diagram showing how the first joint members 1 are stacked.

The first joint member 1 has four inserted parts 11 into which the ends of the pipe members P described above are inserted, and each inserted part 11 is formed at a substantially right angle to the other inserted parts 11 adjacent to each other. It is arranged as follows. In other words, when the first joint member 1 is viewed from the back side (the other side) as shown in FIG. By arranging them so that they face each other, they are formed into a substantially cross shape. Here, the inserted portion 11 is formed into a substantially cylindrical shape with a size that allows the end portion of the substantially cylindrical pipe member P to be inserted therein. Therefore, on the back side of the first joint member 1, the outer surface of each inserted portion 11, that is, the outer surface of the substantially cylindrical shape, is formed in a shape arranged in a substantially cross shape, as shown in FIG. 3(b). has been done. At this time, since the outer surface of each inserted portion 11 is formed of a substantially arcuate surface, a convex portion of a cross-shaped substantially arcuate surface is formed on the back surface side of the first joint member 1. There will be.

On the other hand, on the front side shown in FIG. 3A, which is the opposite side to the back side shown in FIG. A thick portion 12 is formed by protruding the outer surface further toward the outside, that is, toward the front surface. Further, on the surface side of the thick portion 12, as shown in FIGS. 3A and 4A, there is a recess 13 having a substantially cylindrical outer surface arranged in a substantially cross shape, that is, a substantially cross shape. A substantially arcuate recess 13 is formed. This cross-shaped recess 13 has a shape into which the above-mentioned cross-shaped convex portion formed on the back side of the first joint member 1 fits.

FIG. 4B shows how the first joint members 1 described above are stacked. That is, when a plurality of interlocking fences are stacked as described above, the first joint members 1 located at the same location of the interlocking fences are in contact with each other and stacked. At this time, the cross-shaped recess 13 formed on the front side (one side) of the first joint member 1 located on the lower side is filled with the back side (on the other side) of the other first joint member 1 located on the upper side. The cross-shaped convex portions formed on the other surface side are arranged to face each other, and the concave portion 13 and the convex portions fit together. Therefore, the stacked state of the first joint members 1 is stabilized.

Next, the configuration of the second joint member 2 will be described with reference to FIGS. 5 and 6. Note that FIG. 5(a) is a diagram of the second joint member 2 viewed from the front side, FIG. 5(b) is a diagram of the second joint member 2 viewed from the back side, and FIG. 5(c) is a diagram of the second joint member 2. It is a view seen from the side. FIG. 6A is a perspective view of the second joint member 2, and FIG. 6B is a diagram showing how the second joint members 2 are stacked.

The second joint member 2 has two inserted portions 21 into which the ends of the pipe member P described above are inserted, and the two inserted portions 21 are arranged substantially at right angles to each other. In other words, when the second joint member 2 is viewed from the back side (the other side) as shown in FIG. By arranging it toward the other end, it is formed into a roughly curved hook shape. Here, the inserted portion 21 is formed into a substantially cylindrical shape with a size that allows the end portion of the substantially cylindrical pipe member P to be inserted therein. Therefore, on the back side of the second joint member 1, a concave portion is formed between the outer surfaces of each inserted portion 21, that is, between the outer surfaces of the substantially cylindrical portions, as shown in FIG. 5(b). Ru.

On the other hand, as shown in FIG. 6A, the front side of the second joint member 2 shown in FIG. 5(a), which is the opposite side to the back side shown in FIG. A convex portion 22 is formed that protrudes from a location between the insertion portions 21 toward the outside, that is, further toward the surface. This convex portion 22 has a shape that fits into the above-mentioned concave portion formed on the back side of the second joint member 2.

FIG. 6B shows how the second joint members 2 described above are stacked. That is, when a plurality of interlocking fences are stacked as described above, the second joint members 2 located at the same location of the interlocking fences are in contact with each other and stacked. At this time, the convex portion 22 formed on the front side (one side) of the second joint member 2 located on the lower side is attached to the rear side (on the other side) of the other second joint member 2 located on the upper side. The concave portions formed on the surface side) are arranged to face each other, and the convex portion 22 and the concave portion are fitted. Therefore, the stacked state of the second joint members 2 becomes stable.

Next, the configuration of the third joint member 3 will be explained. As shown in FIG. 1, the third joint member 3 has three inserted parts into which the end of the pipe member P described above is inserted, one inserted part and the other inserted part. On the other hand, other inserted portions located on both sides thereof are arranged at substantially right angles. That is, the third joint member 3 is formed in a substantially T-shape. The inserted portion is formed into a substantially cylindrical shape with a size that allows the end portion of the substantially cylindrical pipe member P to be inserted into the inserted portion.

Next, the leg portion F will be explained. First, as shown in FIGS. 1 and 2, the leg portions F are provided on the lower side, which is located below when the interlocking fence is erected, among the sides forming the outer shape of the interlocking fence. At this time, the leg part F is provided on the first joint member 1 which is located at the lower side of the articulated fence and located a predetermined distance inside from both sides in the width direction of the outer shape of the articulated fence. It will be done. Specifically, the leg portion F connects a pipe member P extending further downward to a first joint member 1 provided on the lower side, and connects a third joint member 3 to the lower end of the pipe member P. , furthermore, it is constructed by connecting a pipe member P of a predetermined length to the third joint member 3 along the horizontal direction. Note that the pipe member P horizontally connected to the third joint member 3 serves as a grounding portion that is grounded to the ground.

The leg part F configured as described above is constructed by connecting the third joint member 3 to the pipe member P extending further downward from the lower side of the articulated fence. It is rotatably connected to the state shown in FIG. 2 from the state shown in FIG. For this reason, by rotating the third joint member 3 with respect to the lower side while the pipe member P forming the ground contact portion is connected to the third joint member 3, the pipe member P as shown in FIG. As shown in Figure 2, it can be positioned perpendicular to the plane formed by the interlocking fence, and as shown in Figure 2, it can be positioned parallel to the plane formed by the interlocking fence. can.

In addition, the length of the pipe member P as a grounding part connected to the third joint member 3 is when the pipe member P is positioned parallel to the plane formed by the connecting fence as shown in Fig. 2. In addition, the end portion thereof is formed in such a length that it does not protrude outward from the side of the interlocking fence.

Next, the operation when using the interlocking fence configured as described above will be explained. First, a plurality of pipe members P of a plurality of types are connected in a lattice shape as shown in FIGS. 1 and 2 using a plurality of joint members 1, 2, and 3 of three types, and the outer shape is approximately rectangular. Then, the legs F are connected to the lower side to form an interlocking fence. When the interlocking fence is used by standing on the ground, the legs F are rotated as shown in Fig. 1, so that the pipe member P that becomes the ground contact part is aligned with the surface formed by the interlocking fence. It is placed perpendicular to the

On the other hand, when storing or transporting without using an interlocking fence, first rotate the leg part F as shown in Fig. 2, so that the pipe member P that becomes the ground contact part is formed of the interlocking fence. The position should be parallel to the plane. As a result, the entire articulated fence including the leg portions F has a flat plate shape located on a substantially flat surface, and the leg portions F do not protrude from the sides of the outer shape of the articulated fence. When multiple flat plate-shaped interlocking fences are laid horizontally and stacked, the joint members 1, 2, and 3 located at the same location of the interlocking fences will come into contact with each other. . At this time, the first joint members 1 are stacked as shown in FIG. 4B by being arranged so that the recesses 13 face the same side (front side or back side) at the same location of the interlocking fences. It happens. In other words, the recess 13 of the first joint member 1 fits into the convex portion formed on the side opposite to the surface on which the recess 13 of the other first joint member 1 that is in contact is formed. . Similarly, the second joint member 2 is arranged so that the convex portion 22 faces the same side (front side or back side) at the same location of the interlocking fences, so that the second joint member 2 can be stacked as shown in FIG. 6B. It will be. In other words, the convex portion 22 of the second joint member 2 fits into the concave portion formed on the side opposite to the surface on which the convex portion 22 of the other second joint member 2 that comes into contact is formed. Become. Therefore, the stacked joint members 1 and 2 come into stable contact with each other, and the stacked state of the interlocking fence itself becomes stable.

Note that the first joint member 1 and the second joint member 2 may be arranged in different directions as described below depending on the arrangement location of the connecting fence. For example, the first joint member 1 is arranged so that the recess 13 faces the front side of the paper at the location indicated by reference numeral 1a in FIG. It may be arranged like this. In other words, in the interlocking fence, the first joint members 1 (1a) located diagonally are arranged so that the recesses 13 face the surface side, and the first joint members 1 (1b) located diagonally ) may be arranged so that the recess 13 faces the back side. Similarly, the second joint member 2 is arranged so that the convex portion 22 faces the front side of the paper at the location indicated by the reference numeral 2a in FIG. 22. In other words, in the interlocking fence, the second joint members 2 (2a) located diagonally are arranged so that the convex portions 22 face the front side, and the second joint members 2 (2a) located diagonally 2b) may be arranged so that the convex portion 22 faces the back side. By doing this, the interlocking fences can be stacked stably without worrying about the front and back sides of each other.

Note that the shape of the above-mentioned connecting fence itself and the shape of each joint member 1, 2, and 3 are just examples, and no matter what shape it is, for example, the shape of the first joint member 1 and the second joint member 2 may be The concave portions 13, convex portions 22, convex portions, and concave portions are not limited to the shapes described above, and may have any shape.

Although the present invention has been described above with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments. The configuration and details of the present invention can be modified in various ways within the scope of the present invention by those skilled in the art.
