(First embodiment)
Embodiments of the overturn prevention tool according to the present invention will be described below in detail with reference to the drawings. FIG. 1 and FIG. 2 are views showing a fixture to which a fall prevention tool according to a first embodiment of the present invention is attached, FIG. 1 is a front view, and FIG. 2 is a side view. The overturn prevention tool 1 includes a first square tube 10 as an “inner cover”, a second square tube 20 as an “outer cover”, and a belt (not shown). The fixture 7 has a front surface 70, an upper surface 72, a lower surface 74, a side surface A 76, a side surface B 77, and a back surface 78. The overturn prevention tool 1 has a structure in which the outer wall surface of the first square tube 10 is in contact with the inner wall surface of the second square tube 20 and is detachably inserted. The furniture 7 is placed on the floor surface 80 of the room 8 and placed so that the back surface 78 is in contact with the wall surface 84. On the upper surface 72 of the fixture 7, the overturning prevention tool 1 including the first square tube 10 and the second square tube 20 is placed, and the first square tube 10 and the second square tube 20 are connected by a not-shown lock. And the sum of the length of the exposed portion of the first rectangular tube 10 and the length of the second rectangular tube 20 is a distance between the upper surface 72 of the fixture 7 and the ceiling 82 by a length adjusting means (not shown). It is equal to.

  When strong shaking such as an earthquake occurs in the above state, the fixture 7 receives a force in a direction in which the back surface 78 is separated from the wall surface 84 with the point P at the end of the lower surface 74 in contact with the floor surface 80 as a center point. However, the wall surface 84 side of the upper end 102 of the first square tube 10 of the tipping prevention tool 1 is caught by the ceiling 82, and the back surface 78 of the fixture 7 does not leave the wall surface 84. Therefore, the fixture 7 is prevented from falling by the tipping prevention tool 1.

  FIG. 3 is an explanatory diagram showing that the fixture 7 is prevented from falling by the tipping prevention tool 1. As shown in FIG. 3 (a), when strong shaking due to an earthquake or the like occurs, the fixture 7 rotates around a point P on the lower surface 74 of the fixture 7 as shown by a two-dot chain line, and falls down unless there is a ceiling 82. start. In this case, the point S on the wall surface 84 side of the upper end 102 of the first square tube 10 of the tipping prevention tool 1 draws a locus with the point P as the center. The locus of the point S passes through the upper side of the ceiling 82 as shown by the two-dot chain line in FIG. Here, the point S in the case of FIG. When the fall further proceeds, as shown by the two-dot chain line in FIG. 3 (b), the point S ′ becomes a place point S ″ having almost the same height as the ceiling 82, and after that, it falls below the ceiling 82 and falls. In this way, as the fixture 7 falls, the locus of the point S draws a locus of an arc indicated by the dotted line from the point S ′ to the point S ″. In addition, the locus of this point S ′ point S ″ is located above the ceiling 82. The above is an explanation of the overturn of the fixture 7 if there is no ceiling 82. However, the existence of the ceiling 82 is present. Thus, the point S of the first square tube 10 of the overturning prevention tool 1 is caught by the ceiling 82 and does not draw an arc as shown by a two-dot chain line. In this embodiment, the fall-adjusting tool 1 can be placed on the upper surface 72 of the fixture 7 with no gap between the ceiling 82 and the ceiling 82 in this embodiment. The point S hardly moves, so that a partial fall does not occur in the gap between the fixture 7 and the ceiling 82, and the fall prevention tool 1 is not broken at all.

  FIG. 4 is a perspective view of a tipping prevention tool according to the first embodiment of the present invention, and FIG. 5 is a plan view of the tipping prevention tool. The tipping prevention tool 1 includes a first square tube 10 as an “inner cover”, a second square tube 20 as an “outer cover”, and four belts as “belt-shaped members”. Is done. The first square tube 10 has a substantially rectangular cross section, and has an upper end portion 102, a lower end portion 104, an inner wall surface 106, and an outer wall surface 108. The second square tube 20 has a substantially rectangular cross section, and has an upper end portion 202, a lower end portion 204, an inner wall surface 206, and an outer wall surface 208. The four belts include a first belt 32, a second belt 34, a third belt 36, and a fourth belt 38. The first belt 32 has an end A322 and an end B324, the second belt 34 has an end C342 and an end D344, the third belt 36 has an end E362 and an end F364, and a fourth belt. The belt 38 has an end portion G382 and an end portion H384.

  The first square tube 10 is removably inserted inside the second square tube 20. In this case, there is a slight gap 25 between the outer wall surface 108 of the first rectangular tube 10 and the inner wall surface 206 of the second rectangular tube 20. Therefore, the first square tube 10 and the second tube 20 are locked as follows. That is, the end portion A322 of the first belt 32 is affixed to one surface of the four outer wall surfaces 208 of the second rectangular tube 20 with an adhesive or the like, and is bent at the upper end portion 202 of the second rectangular tube 20. Then, the gap 25 is inserted, and further bent at the lower end of the first square tube 10, and the end B324 is attached to the four inner wall surfaces 106 of the first square tube 10 with an adhesive or the like. Similarly, the end portion C342 of the second belt 34 is attached to one surface of the outer wall surface 208, and the end portion B344 is attached to the inner wall surface 106 with an adhesive or the like.

  In this state, when the first corner 10 is inserted from the upper part of the second rectangular tube 20, the first belt 32 near the lower end of the rectangular tube 10 that was initially pushed in is inserted. The slack is reduced as it is pushed in, finally disappears, and the first belt 32 becomes taut. As a result, the first square tube 10 and the second corner 20 are locked against the pushing force from above by the first belt 32. The same applies to the second belt 34, the third belt 36, and the fourth belt 38.

  Next, adjustment of the sum of the length of the exposed portion of the first rectangular tube 10 and the length of the second rectangular tube 20, that is, the upper end portion 102 of the first rectangular tube 10 and the lower end of the second rectangular tube 20 is performed. Adjustment of the length with the unit 204 is performed as follows. The position where the end portion A322 of the first belt 32 is attached to the outer wall surface 208 of the second rectangular tube 20 with an adhesive or the like, or the end portion B324 of the first belt 32 is the four surfaces of the first rectangular tube 10 By adjusting the position where the adhesive is attached to an inner wall surface 106 and adjusting the length of the first belt 32, the length of the exposed portion of the first rectangular tube 10 and the second rectangular tube 20 are adjusted. The sum with the length can be adjusted. The same applies to the second belt 34, the second belt 34, the third belt 36, and the fourth belt 38.

  Both the first square tube and the second square tube are made of cardboard or the like for the purpose of weight reduction. Also, metals such as wood and aluminum are used to increase the strength. In some cases, these corrugated cardboard, wood and metal are used in combination. The four tapes are made of paper, vinyl or the like. In addition, although the 1st square tube and the 2nd square tube showed both the cases where the cross section is a substantially square cylinder shape, the case where a cross section is a substantially elliptical shape is also included.

  As a result of the above, the overturning prevention tool 1 composed of the first rectangular tube 10 and the second rectangular tube 20 is locked against the pressing force from the ceiling 82 which is generated by strong shaking such as an earthquake, and is long. The sum of the length of the exposed portion of the first rectangular tube 10 and the length of the second rectangular tube 20 can be accurately adjusted to the distance between the upper surface 70 of the fixture 7 and the ceiling 82 by the height adjusting means. Therefore, a partial fall does not occur in the gap between the fixture 7 and the ceiling 82, and the destruction of the fall prevention tool 1 due to this does not occur at all.
