(4) The apparatus 1 configured as described above is provided with four cylinders 5 as described below. First, the plate 2 is placed on the installation surface 6, and the plate 2 is fixed to the installation surface 6 with the anchor bolt 7. Next, the first cylinder 5 is placed on the plate portion 2. At this time, as shown in FIG. 2, the cylinder 5 is arranged outside the hooked portion 313 on which the cylinder 5 is to be hooked. Then, the band 4 is passed through the cylinder 5 from above and fitted to the cylinder 5, the cylinder 5 is wound by the winding portion 41, the hooking portion 42 is directed inward, and the band 4 is passed through the hooking portion 313. To wear. Similarly, the second to fourth cylinders 5 are respectively placed on the plate portion 2, and the band 4 is externally fitted to the band portion 313.

Here, the entire shape of the band 4 does not change like a chain, and the entire shape is substantially fixed in a ring shape protruding outward in a substantially L-shape. , That is, the bent portion of the hook portion 42 is hooked to the hook portion 313. Therefore, the arrangement position of the cylinder 5 to which such a band 4 is externally fitted is regulated by the position of the hooked portion 313. As shown in FIG. 2, each of the hooks 313 is arranged such that the other hooks 313 are located substantially symmetrically with respect to the center of the column 3. 5 is arranged such that another cylinder 5 comes to a position substantially symmetrical with respect to the center of the column 3.

As described above, since the other cylinders 5 are disposed at positions substantially symmetrical with respect to the cylinders 5 in the plan view with respect to the center of the column 3, the four sides of the plate portion 2 are substantially equally distributed. The plate portion 2 is held down by its own weight, and therefore, even if vibrations or the like due to an earthquake occur, there is little possibility that the plate portion 2 will rise from the installation surface 6. The cylinder 5 is supported by the support portion 31 via the band 4. However, since the support portion 31 is provided not on the wall surface of the building but on the support portion 3 erected on the plate portion 2, the support portion 31 is supported. The possibility that the part 3 itself falls off from the installation location is small. Therefore, the possibility that the cylinder 5 falls down is small.

Further, since the attached portions 313 are provided at positions substantially overlapping with the perpendicular bisectors of each side of the plate portion 2 in plan view, the cylinder 5 is also viewed in plan as shown in FIG. In this case, each of the sides of the plate portion 2 is provided at such a position as to be approximately bisected by a vertical bisector of each side, so that the plate portion 2 is pressed in four directions with good balance.

In FIG. 1, the first column 32 is connected to the lower part of the support 31, and the second column 33 is connected to the upper part of the support 31. However, when the height of the cylinder 5 is low, FIG. As shown in the figure, the first column 32 is connected to the upper part of the support 31, the second column 33 is connected to the lower part of the support 31, and the second column 33 is connected to the column fixing part 21. By connecting, the position of the support part 31 can be lowered, and the cylinder 5 can be supported at an appropriate position according to its height.

Further, the device 1 can be used as a device for arranging two cylinders. In such a case, the four attachment portions 313 are located at positions substantially symmetric with respect to the center of the column 3. Two cylinders are arranged using the two attached portions 313.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 10 is a perspective view of the cylinder overturn prevention device 10 of the second embodiment in which two cylinders 5 are arranged, and FIG. 11 is a plan view thereof. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be appropriately omitted. Note that the support portion 310 is configured in the same manner as the support portion 31, but has different functional parts, so different reference numerals are used.

The apparatus 10 includes a plate portion 20, a column portion 3 erected at the center of the plate portion 20, a band 4 fitted externally to the cylinder 5 and hung on a support portion 310 of the column portion 3, And an anchor bolt 7 for fixing 20 to the installation surface.

The plate portion 20 is made of metal such as stainless steel, and includes a substantially rectangular (excluding a substantially square here) plate-like base portion 25 and a column fixing portion 21 erected at the center of the base portion 25. It has a substantially rectangular shape other than a substantially square shape in plan view.

支 The support portion 3 is erected and fixed to the plate portion 20. A support portion 310 is provided at an intermediate portion of the support portion 3. Here, the support portion 310 has the same structure as the support portion 31 of the first embodiment in order to share components. However, the two portions provided as the attachment portions 313 are provided at positions substantially overlapping the vertical bisectors (shown by two-dot chain lines in FIG. 11) of the short sides of the plate portion 20 in plan view. The member 314 that is only the hooked portion 313 and is used as the hooked portion 313 in the first embodiment is not used as the hooked portion 313 in the second embodiment.

Two cylinders 5 are arranged in the apparatus 10 as follows. First, the plate portion 20 is fixed to the installation surface with the anchor bolt 7. Then, the first cylinder 5 is placed on one side in the longitudinal direction on the plate portion 2, the band 4 is externally fitted to the cylinder 5, and the band 4 is attached to the hooked portion 313 on the same side. Hang on. Next, the second cylinder 5 is placed on the other side in the longitudinal direction on the plate portion 2, the band 4 is fitted over the cylinder 5, and the band 4 is attached to the attachment portion 313 on the same side. Hang on.

As a result, as shown in FIG. 11, the two cylinders 5 are arranged at positions substantially symmetric with respect to the center of the column 3 in plan view, and both sides of the plate portion 20 are substantially evenly arranged. Will be held down by its own weight. For this reason, even if vibrations or the like due to an earthquake occur, there is little possibility that the plate portion 20 will rise from the installation surface. And since the possibility that the support part 310 itself which supports the cylinder 5 falls off from the installation location is small, the possibility that the cylinder 5 will fall down is also small. Further, compared to the plate portion 2 of the first embodiment, the plate portion 20 of the second embodiment requires a small installation space, so the device 10 is suitable for a place where there is no room for the installation space, such as a home. .

In the apparatus 10, the support section 310 having the same structure as the support section 31 is used in order to share parts with the apparatus 1, but the support section 310 having no member 314 may be used.

Further, in the device 1 of the first embodiment, the attached portions 313 are respectively disposed at positions substantially overlapping the diagonal lines of the plate portion 2 in plan view, and the cylinders 5 are disposed on the diagonal lines of the plate portion 2. It may be configured as follows. Even with such a configuration, the four sides of the plate portion 2 are substantially uniformly pressed by the weight of the cylinder 5.

Further, the shapes of the plate portion 2 and the plate portion 20 can also be changed. For example, the plate portion 2 is configured to have a substantially octagonal shape in plan view, or the plate portion 20 is configured to be substantially elliptical in plan view. Or may be configured.

Further, the shapes of the band 4 and the attached portion 313 are not limited to those described above. For example, as shown in FIG. As shown in FIG. 12 (b), a small-diameter annular member 41 is connected to a connecting member 44 having a hook portion 42 having a shape, or an annular winding portion 41 having a diameter slightly larger than the diameter of the cylinder 5. The attachment portions 42 may be connected. As shown in FIG. 13, when the hanging portion 42 is hooked on the hanging portion 313, the hanging portion 313 is connected to the outer periphery of the column 3 in order to reduce the play of the hanging portion 42. A shape having a width corresponding to the hooking portion 42 in the tangential direction may be used.

バ ン ド Also, the band 4 may be a chain. However, if the entire shape of the band 4 is substantially fixed as described above, the band 4 is hardly displaced when wound around the cylinder 5, and the cylinder 5 is hard to move from the arrangement position.

That is, the present invention can adopt various configurations without departing from the scope of the claims for utility model registration.
