However, with the above-mentioned conventional structure, when storing an unused fence, a depth that can accommodate the legs is required, which limits the storage space and puts pressure on the storage space. Ta. Furthermore, if the legs are made smaller, it becomes easier to store the fence, but if the legs are too small, there is a problem in that the fence cannot be erected stably.
Therefore, an object of the present invention is to provide a leg structure for a fence that is easy to store and can stably support the fence.

In order to solve the above-mentioned problems, the present invention includes a first leg member and a second leg member that can be grounded to support the posts of a fence, and the first leg member is at least one of the posts of the fence. The second leg member includes a column forming a part of the column, and a first support fixed to the lower end of the column so as to be orthogonal to the column, and the second leg member is arranged above the first support. a second support part that can be placed on the column, and is rotatably and vertically movably attached to the pillar part, and the second leg member is rotated with respect to the first leg member. Accordingly, the first support part and the second support part are configured to be able to take an open state in which they are open to each other, and a closed state in which the second support part is stacked on the first support part, and the By moving the second leg member up and down with respect to the first leg member, the first leg member and the second leg member are engaged with each other and cannot be rotated, and a fixed state is achieved. It is configured to be able to switch between a movable state in which the engagement between the first leg member and the second leg member is released.

The present invention is as described above, and by rotating the second leg member with respect to the first leg member, the first support part and the second support part can be brought into an open state where they are open to each other, and a second It is configured to be able to take a closed state in which the support part is superimposed on the first support part. Therefore, during use, the fence can be stably supported in the open leg state. Furthermore, by closing the legs when storing, the legs can be folded into a small size for storage.

Moreover, by moving the second leg member up and down relative to the first leg member, a fixed state in which the first leg member and the second leg member are engaged with each other and cannot be rotated, and a fixed state in which the first leg member and the second leg member cannot be rotated can be achieved. It is configured to be able to switch between a movable state in which the engagement between the leg member and the second leg member is released. Therefore, the above-described open leg state and closed leg state can be switched by a simple operation of lifting and rotating the second leg member. Further, since no special structure is required for fixing the second leg member, the fence can be manufactured with a reduced number of parts.

It is an exploded view explaining the structure of a fence. (a) An exploded view of the legs, (b) a view of the legs in an open state, and (c) a view of the legs in a closed state.

Embodiments of the present invention will be described with reference to the drawings.
The fence 10 according to this embodiment is a movable fence 10 that can be used as a partition, a gate, an enclosure, a fence, etc., and can be left in any location.

The fence 10 according to the present embodiment is configured to be expandable and retractable, and includes a plurality of pillars 11 and a fence main body 15 disposed between the pillars 11, as shown in FIG. The fence main body 15 according to this embodiment is composed of a link mechanism that can be expanded and contracted.

In addition, in this embodiment, although the fence main body 15 is comprised by the link mechanism which can expand and contract between the pillars 11, it is not limited to this. For example, any member that functions as the fence 10, such as a panel, a lattice, or a net, may be used as the fence body 15 and placed between the supports 11 instead of the link mechanism. Further, in this embodiment, the number of columns 11 is three, but the number is not limited to this, and the number of columns 11 can be set arbitrarily. That is, one fence main body 15 may be provided between two posts 11, or four or more posts 11 may be provided, and a fence main body 15 may be provided between each of these posts 11.

The support column 11 is a long member disposed substantially perpendicular to the ground, and is made of hollow aluminum material, for example. As shown in FIG. 4, the support column 11 according to the present embodiment is vertically separable. Specifically, each support post 11 can be separated into an upper part to which both ends of the fence body 15 are connected, and a lower part (post part 21 to be described later) forming the leg part 12. The upper and lower parts of the support column 11 are formed of pipes that can be inserted into and removed from each other, and are integrally fixed with fasteners such as bolts.

The fence main body 15 is a part that is provided between adjacent pillars 11 and functions as a partition or a blindfold. The fence main body 15 according to the present embodiment is a link mechanism including a plurality of link bars 16 arranged in a diagonal grid pattern and a rotation shaft 17 that rotatably connects the intersecting link bars 16. This link mechanism constitutes a pantograph mechanism with a link bar 16 rotatably connected by a rotation shaft 17, and as shown in FIGS. 1 and 2, it can be expanded and contracted by changing the angle of the link bar 16. It is composed of

In this embodiment, one set of fence bodies 15 is provided between adjacent pillars 11, and each of these fence bodies 15 is independently expandable and retractable. That is, one fence main body 15 can expand and contract independently without affecting the expansion and contraction of other fence main bodies 15.

Further, both ends of these fence bodies 15 are each attached to the pillars 11 so as to be horizontally rotatable. Therefore, the fence main body 15 is rotatable around the support 11. With this configuration, the plurality of fence bodies 15 can be arranged at any angle. For example, in addition to arranging the plurality of fence bodies 15 in a straight line, it is also possible to arrange the plurality of fence bodies 15 in a bent manner as shown in FIG. Furthermore, when the fence 10 is not in use, the fence 10 can be folded as shown in FIG.

By the way, the support column 11 according to this embodiment includes a leg portion 12 at the lower end. As shown in FIG. 1, the legs 12 can be expanded into an X-shape in plan view and can support the support column 11 so that it does not fall. As shown in FIG. 4, the leg portion 12 includes a first leg member 20 and a second leg member 30 that can be grounded to support the pillars 11 of the fence 10.
The first leg member 20 is an inverted T-shaped member as shown in FIGS. 4 and 5, and includes a column part 21 and a first support part 22.

The column portion 21 is a rod-shaped portion and constitutes at least a portion of the column 11. The column part 21 according to this embodiment constitutes the lower part of the column 11 and can be connected to the upper part of the column 11. Specifically, the column portion 21 according to the present embodiment is configured as a pipe that can be inserted into a pipe that constitutes the upper part of the column 11. A straight support 11 is constructed by inserting the pipe of the pillar 21 into the upper pipe and fixing it with a fixture such as a bolt.

In addition, in this embodiment, although the pillar part 21 comprised the lower part of the pillar 11, it is not limited to this, and the pillar part 21 may comprise the entire pillar 11. That is, the column 11 may be used as it is as the column 21 of the first leg member 20.

The first support portion 22 is a portion fixed to the lower end of the column portion 21 so as to be perpendicular to the column portion 21 described above. The first support portion 22 according to the present embodiment is a prismatic portion fixed to the lower end portion of the column portion 21 in an inverted T shape. The first support portion 22 can support the fence 10 with its lower surface being in contact with the ground.

Further, the second leg member 30 is a member that is rotatably and vertically movably attached to the pillar portion 21 of the first leg member 20 described above. The second leg member 30 is an inverted T-shaped member as shown in FIGS. 4 and 5, and includes a cylindrical portion 31 and a second support portion 32.

The tube portion 31 is a cylindrical portion through which the column portion 21 can be inserted, as shown in FIG. The inner diameter of this cylindrical portion 31 is formed to be slightly larger than the outer diameter of the columnar portion 21. By penetrating this cylinder part 31 with the pillar part 21, the cylinder part 31 can slide in the axial direction (vertical direction) of the pillar part 21 and can rotate in the circumferential direction (horizontal direction) of the pillar part 21. It has become.

The second support portion 32 is a portion fixed to the lower end of the cylindrical portion 31 so as to be perpendicular to the cylindrical portion 31 described above. The second support portion 32 according to the present embodiment is a portion having a U-shaped cross section and fixed to the lower end portion of the cylindrical portion 31 in an inverted T shape. Specifically, as shown in FIG. 5, the second support portion 32 includes a horizontal upper plate portion 32a connected to the lower end of the cylindrical portion 31, and a horizontal upper plate portion 32a extending downward from both ends of the upper plate portion 32a. A pair of side plate portions 32b are provided. As a result, the second support portion 32 has an opening 32d that opens downward in cross-sectional view. This opening 32d is for engaging the first support part 22, as will be described later, and is opened to a size that allows the first support part 22 to fit completely therein. That is, the internal space of this opening 32d is formed to be approximately equal in height and width to the first support portion 22 in cross-sectional view.

Further, a notch portion 32c that opens downward is formed in the center portion of the pair of side plate portions 32b (a portion directly below the cylindrical portion 31 in side view). This notch 32c is for engaging the first support part 22, as will be described later, and has an opening large enough to allow the first support part 22 to fit therein. That is, the inner side of this notch portion 32c is formed to be approximately equal in height and width to the first support portion 22. In addition, since the rigidity of the second support part 32 is reduced by forming this notch part 32c, in this embodiment, the connection point between the cylindrical part 31 and the second support part 32 (above the notch part 32c) Ribs 33 are provided to reinforce the second support portion 32.

This second support part 32 can support the fence 10 in cooperation with the first support part 22, as shown in FIG. 5(b). When the fence 10 is supported by the second support part 32, the second support part 32 is arranged to be orthogonal to the first support part 22 in plan view. By arranging it in this way, the lower end of the second support part 32 is in contact with the ground, and the fence 10 can be supported. Moreover, when this second support part 32 is not used, the second support part 32 can be placed on the first support part 22, as shown in FIG. 5(c).

In this way, in the leg portion 12 according to the present embodiment, the first support portion 22 and the second support portion 32 are mutually connected by rotating the second leg member 30 with respect to the first leg member 20. It is configured to be able to take an open leg state (the state shown in FIG. 5(b)) and a closed state (the state shown in FIG. 5(c)) in which the second support part 32 is overlapped with the first support part 22. ing.

Note that when the user wants to change the leg portion 12 from the open leg state to the closed leg state or from the closed leg state to the open leg state, the user lifts the second leg member 30 upward, and the first leg member 20 The engagement between the second leg member 30 and the second leg member 30 is released, and the second leg member 30 becomes rotatable. Then, by rotating the second leg member 30 to the open leg state or the closed leg state and then lowering it downward, the first leg member 20 and the second leg member 30 engage with each other, and the second leg member 30 engages with the second leg member 30. The member 30 becomes unable to rotate.

In this way, the leg section 12 according to the present embodiment can be configured such that the first leg section 20 and the second leg section 30 are connected by moving the second leg section 30 up and down relative to the first leg section 20. The first leg member 20 and the second leg member 30 are configured to be switchable between a fixed state in which they are engaged with each other and cannot be rotated, and a movable state in which the first leg member 20 and the second leg member 30 are disengaged.
Note that the fixed state according to the present embodiment is realized using the opening 32d and the notch 32c of the second support portion 32.

That is, as shown in FIG. 5(c), when the first leg member 20 and the second leg member 30 are in the closed and fixed state, the first support portion 22 is engaged with the inside of the opening 32d. This prevents the second leg member 30 from rotating relative to the first leg member 20.

Further, as shown in FIG. 5(b), when the first leg member 20 and the second leg member 30 are in the open and fixed state, the first support part 22 is engaged with the notch part 32c. This prevents the second leg member 30 from rotating relative to the first leg member 20.

As explained above, according to the present embodiment, by rotating the second leg member 30 with respect to the first leg member 20, the first support part 22 and the second support part 32 are opened to each other. It is configured so that it can take an open leg state and a closed leg state where the second support part 32 is superimposed on the first support part 22. Therefore, during use, the fence 10 can be stably supported in the open leg state. Furthermore, by keeping the legs closed when storing, the legs 12 can be folded into a small size for storage.

That is, in the open leg state, the first support part 22 and the second support part 32 are assembled in an X shape in a plan view, so the fence 10 can be supported in all directions (unlike the conventional I In the case of a leg portion having a letter shape, it is weak against force in a direction perpendicular to the longitudinal direction of the leg portion, and cannot support the fence 10 in all directions). Therefore, even with a structure in which a plurality of fence bodies 15 can be arranged at any angle as in this embodiment, the fence 10 can be stably supported regardless of the angle of the fence bodies 15.

In addition, in the closed leg state, as shown in FIG. can be closed. Therefore, the depth required for storing the fence 10 is minimized, and the fence 10 can be stored compactly. In addition, in this embodiment, since the fence main body 15 is rotatable around the support posts 11, the fence main body 15 is rotated so that the width direction of the fence main body 15 and the longitudinal direction of the legs 12 match. If so, the depth of the fence 10 can be reduced as shown in FIG. However, even if the fence main body 15 cannot rotate around the pillar 11, if it is configured so that the longitudinal direction of the first support part 22 and the width direction of the fence main body 15 match, the structure shown in FIG. As shown, the depth of the fence 10 can be reduced.

Furthermore, in the fence 10 according to the present embodiment, by moving the second leg member 30 up and down relative to the first leg member 20, the first leg member 20 and the second leg member 30 are engaged with each other. It is configured to be switchable between a fixed state in which the first leg member 20 and the second leg member 30 are disengaged from each other and a fixed state in which they cannot be rotated together. Therefore, the above-described open leg state and closed leg state can be switched by a simple operation of lifting and rotating the second leg member 30. Moreover, since a special structure for fixing the second leg member 30 is not required, the fence 10 can be manufactured with a small number of parts.
