  FIG. 1 shows a state where the fall prevention furniture 1 which is one of the embodiments of the present invention is installed. The fall prevention furniture 1 is installed in a space 93 between the furniture 91 and the ceiling 92 in a state of being placed on the furniture 91. The overturn prevention furniture 1 includes a box-shaped storage unit 10 and an inverted L-shaped lifting unit 20 disposed in a rear direction (rear direction) 112 of the storage unit 10. The storage unit 10 is a rectangular parallelepiped hollow body as a whole, and can store objects by opening and closing the two left and right doors 16a and 16b provided in the front direction (front direction) 111. The elevating unit 20 is a rectangular plate-like slide back plate 21 extending in the vertical direction 100 and a plate-like shape attached to the end portion 21 a of the slide back plate 21 in the upward direction 101 at a substantially right angle to the slide back plate 21. The flat plate 25 is provided. The elevating unit 20 can be moved up and down in the vertical direction 100. In this example, the flat plate 25 is close to the ceiling 92, and the slide back plate 21 is in contact with the wall 94 between the furniture 91 and the ceiling 92. The storage unit 10 is set by means 40.

  FIG. 2 schematically shows a state in which the fall prevention furniture 1 is installed in a cross-sectional view. As shown in FIGS. 1 and 2, the storage unit 10 includes a first back plate (main body back plate) 11 that constitutes the back surface, a top plate 12 that constitutes the top surface, a bottom plate 13 that constitutes the bottom surface, Side plates 14 and 15 constituting the side surfaces of the door and doors 16 (16a and 16b) constituting the front surface. A slide back plate (second back plate) 21 of the elevating unit 20 is set on the main body back plate 11 of the storage unit 10 by a fixing means 40. That is, the fall prevention furniture 1 includes a storage unit 10 installed between the furniture 91 and the ceiling 92, a first back plate (main body back plate) 11 constituting the back surface of the storage unit 10, and a main body back plate 11. A second back plate 21 arranged in the rear direction 112, the second back plate (slide back plate) 21 moving up and down in the vertical direction 100 along the main body back plate 11, and the slide back plate 21 as the main body And fixing means 40 for fixing to the back plate 11. In the fall prevention furniture 1, since the main body back plate 11 and the slide back plate 21 are in contact with each other, that is, the two plates are fixed in a surface contact state, the storage unit 10 has a simple configuration. Can be firmly and stably connected to the lifting unit 20.

  As shown in FIG. 2, when rolling in the front-rear direction 110 occurs with respect to the furniture 91 due to an earthquake or the like, the furniture 91 has a moment (falling moment) 81 that tends to rotate about the lower end portion 91 a of the front direction 111. Works. In the fall prevention furniture 1, the slide back plate 21 is fixed to the main body back plate 11 in a state where the slide back plate 21 is slid in the upward direction 101 and the flat plate 25 is brought close to the ceiling 92. Therefore, a moment (resistance moment) 82 that opposes the lifting (lifting) of the upper end portion 91b of the furniture 91 in the rear direction 112 can act on the furniture 91, and the furniture 91 can be prevented from falling. Since the slide back plate 21 extends in the upward direction 101 along the wall 94 from the upper end portion 91b that easily lifts when the furniture 91 falls, a resistance moment 82 that opposes the fall moment 81 accompanying the roll in the front-rear direction 110. Is easy to act on the furniture 91.

  As shown in FIGS. 1 and 2, in the fall prevention furniture 1, the storage unit 10 can effectively use a space 93 between the furniture 91 and the ceiling 92 as a storage space. Further, the slide back plate 21 is set along the main body back plate 11 and the wall 94 so that the elevating unit 20 does not protrude into the space 93 a in the upward direction 101 of the storage unit 10. For this reason, the slide back plate 21 arranged along the wall 94 is difficult to enter the field of view of the user who uses the fall-preventing furniture 1 and is difficult to stand out. Therefore, the fall prevention furniture 1 can provide a clean appearance (design) with no or very little pressure on the user and without any obstruction in the space 93a in the upper direction 101 of the storage unit 10.

  Further, since the slide back plate 21 is a single plate, it is easy to adjust to the wall 94 by adjusting the color, and it is easy to achieve harmony with the furniture 91 and other furniture. For this reason, it is easy to give the user who uses this fall prevention furniture 1 the aesthetics (impression) as if the slide back plate 21 is melted into the wall 94 without giving a feeling of pressure or discomfort. Furthermore, since the slide back plate 21 is a single plate, the slide back plate 21 is resistant to rolling in the left-right direction 120 and easily increases the contact area with the wall 94. For this reason, in this fall-preventing furniture 1, since the two surfaces of the flat plate 25 and the ceiling 92, the slide back plate 21 and the wall 94 are in contact, the furniture 91 is supported even in a lateral direction 120 roll. It's easy to do. Furthermore, in the fall prevention furniture 1, the flat plate 25 of the lifting unit 20 is fixed in a state of being close to the ceiling 92, that is, the flat plate 25 is fixed in a non-contact state slightly apart from the ceiling 92. It is easy to suppress giving.

  FIG. 3 is a perspective view of the fall prevention furniture 1 as viewed from the front direction 111. FIG. 4 is a perspective view of the fall prevention furniture 1 viewed from the rear direction 112. As shown in FIG. 3, the top plate 12 of the storage unit 10 is provided with a hole 12 a penetrating the top plate 12 in the vertical direction 100 at a position close to the main body back plate 11. The fall prevention furniture 1 further includes lifting / lowering means 30 that lifts and lowers the slide back plate 21 in the vertical direction 100. The elevating means 30 penetrates the hole 12a of the top plate 12, and a first height adjusting bolt 31 capable of elevating the flat plate 25 of the elevating unit 20 in the vertical direction 100, a nut 33 set in the hole 12a, A handle 34 for rotating the height adjusting bolt 31 is provided. For this reason, by operating the handle 34 and raising the height adjusting bolt 31, the slide back plate 21 can be pushed up and the flat plate 25 can be adjusted to a predetermined height in the vertical direction 100.

  As shown in FIG. 4, the slide back plate 21 includes two slits (grooves) 22 for height adjustment that extend in the upward direction 101 from the end portion 21 b in the downward direction 102. As described above, the fall prevention furniture 1 includes the fixing means 40 that fixes the slide back plate 21 to the main body back plate 11. As shown in FIGS. 3 and 4, the fixing means 40 includes two plates 41 extending in the left-right direction 120 sandwiching the slide back plate 21 together with the main body back plate 11 from the rear direction 112, and the plate 41 through the slit 22. And four sets of bolts 42 and nuts 43 that connect the main body back plate 11 to each other. For this reason, the slide back plate 21 pushed up to a predetermined height by the height adjusting bolt 31 can be fixed to the main body back plate 11. Furthermore, the height adjusting bolt 31 can be removed after the slide back plate 21 is fixed to the main body back plate 11, and it is possible to prevent the user from feeling uncomfortable. The main body back plate 11 is provided with a pair of left and right holes 11a through which the bolts 42 are passed, in three stages (rows) according to the height at which the slide back plate 21 is fixed. The slide back plate 21 of this example is fixed by inserting four sets of bolts 42 into the two-step holes 11 a in the upper direction 101 of the main body back plate 11. The number and arrangement of the holes 11a are not limited to this example.

  As shown in FIG. 4, the two slits 22 symmetrical in the left-right direction 120 formed in the slide back plate 21 are below the center 102 in the vertical direction 100 of the slide back plate 21, that is, below the slide back plate 21. It is placed at half the position. Therefore, as shown in FIG. 3, when the slide back plate 21 is pushed upward along the main body back plate 11, the slit 22 hardly appears in the front direction 111, and the slit 22 enters the user's field of view. It is easy to suppress. Furthermore, since the slit 22 is disposed at the lower half position of the slide back plate 21, it is possible to suppress the strength of the slide back plate 21 from being lowered. Further, as shown in FIGS. 3 and 4, a cosmetic material 17 that covers the slide back plate 21 from the left-right direction 120 is attached to the rear direction 112 of the main body back plate 11. For this reason, it can prevent that the slide back board 21 appears in the state exposed in the left-right direction 120, and can improve the beauty | look of the fall prevention furniture 1. FIG.

  The size and shape of the slide back plate 21 and the main body back plate 11 are not limited to this example. The length h2 in the vertical direction 100 of the slide back plate 21 of this example is about 1.5 times the length h1 of the main body back plate 11 in the vertical direction 100, but h2 is substantially the same as h1. Good. When the length (height) in the vertical direction 100 of the space 93 between the furniture 91 and the ceiling 92 is large, the distance to push up the slide back plate 21 tends to increase, so h2 is 1.4 to 1 of h1. It is easy to secure a contact area between the slide back plate 21 and the main body back plate 11 by setting it to about 6 times. For example, when the furniture 91 has a height of 180 cm, a height from the floor to the ceiling 92 of 245 cm, and the fall prevention furniture 1 having h1 of 40 cm is installed in the space 93, h2 is about 55 to 65 cm. Is preferred. The same applies to the following embodiments.

  On the other hand, when the length (height) in the vertical direction 100 of the space 93 between the furniture 91 and the ceiling 92 is small, it is preferable that h2 is about 1.0 to 1.1 times h1. For example, when the furniture 91 has a height of 200 cm, a height from the floor to the ceiling 92 of 245 cm, and the fall prevention furniture 1 having h1 of 40 cm is installed in the space 93, h2 is about 40 to 45 cm. Is preferred. Thus, when the space 93 between the furniture 91 and the ceiling 92 is small, the distance to push up the slide back plate 21 is also reduced, and thus the slide back plate 21 can be further prevented from entering the user's field of view. The same applies to the following embodiments.

  Moreover, although the raising / lowering means 30 and the fixing means 40 of this example are examples which can be performed simply and at low cost, they are not limited to this example. In addition, the flat plate 25 of the present example is fixed in a state in which the flat plate 25 is brought close to the ceiling 92, but can be fixed in a state in which the flat plate 25 is in contact with the ceiling 92. As described above, since the slide back plate 21 extends in the upward direction 101 along the wall 94 from the upper end portion 91b that easily lifts when the furniture 91 falls, the slide 91 further acts on the furniture 91 with a resistance moment against the fall moment. The furniture 91 can be easily supported not only by the roll in the front-rear direction 110 but also by the vertical shake in the up-down direction 100. The same applies to the following embodiments.

  Further, the flat plate 25 is attached so as to slightly protrude from the end portion 21a of the slide back plate 21 in the front direction 111, but the size and shape of the flat plate 25 are not limited to this example, and for example, the front direction of the flat plate 25 It is also possible to give the user a soft aesthetic (impression) by making the end of 111 round. Further, the T-shaped lifting unit 20 can be configured by attaching the flat plate 25 so as to slightly protrude in the rear direction 112 from the end portion 21a of the slide back plate 21. In addition, it is possible to provide an unevenness (tenon) between the bottom plate 13 of the storage unit 10 and the upper surface of the furniture 91 to improve the fall prevention effect. Moreover, the fall prevention furniture 1 of this example can be installed in various furniture, such as a chiffon, a closet, a bookshelf, a cupboard, and a cabinet. The same applies to the following embodiments.

  FIG. 5 is a perspective view of the fall prevention furniture 1a, which is one of the different embodiments of the present invention, as seen from the front direction 111. FIG. FIG. 6 is a perspective view of the fall prevention furniture 1a viewed from the rear direction 112. FIG. As shown in FIG. 5, the top plate 12 of the storage unit 10 is provided with a slit 12 b that penetrates the top plate 12 in the vertical direction 100 and extends in the horizontal direction 120 at a position facing the main body back plate 11. . For this reason, the slide back plate 21 of this example is inserted into the storage unit 10 through the slit 12 b of the top plate 12. Furthermore, the slide back plate 21 includes a protruding plate (projecting portion) 26 provided in a lower direction 102 than the top plate 12. The protruding plate 26 is attached so as to protrude slightly in the front direction 111 at a substantially right angle to the slide back plate 21. The elevating means 30 is set on the pedestal, a second height adjusting bolt 32 that can raise and lower the protruding plate 26 of the slide back plate 21 in the vertical direction 100, a pedestal 35 that supports the two height adjusting bolts 32, and the like. A nut 33 and a handle 34 for rotating the height adjusting bolt 32 are provided. Therefore, by operating the handle 34 and raising the height adjusting bolt 32, the slide back plate 21 can be pushed up and the flat plate 25 can be adjusted to a predetermined height in the vertical direction 100. In the following embodiments, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 5 and FIG. 6, the fixing means 40 of the present example includes a slide back plate 21 and two plates 41 extending in the left-right direction 120 sandwiching the main body back plate 11 from the front direction 111 and the slit 22. The plate 41 and the main body back plate 11 are provided with four sets of bolts 42 and nuts 43. That is, the fall prevention furniture 1a of this example also includes the storage unit 10 installed between the furniture 91 and the ceiling 92, the first back plate (main body back plate) 11 constituting the back surface of the storage unit 10, and the main body back. A second back plate 21 disposed in the front direction 111 of the plate 11, which is a second back plate (slide back plate) 21 that moves up and down in the vertical direction 100 along the main body back plate 11, and a slide back plate 21. And fixing means 40 for fixing to the back plate 11 of the main body.

  Also in the fall prevention furniture 1a, the slide back plate 21 can be fixed to the main body back plate 11 in a state where the slide back plate 21 is slid in the upward direction 101 and the flat plate 25 is brought close to the ceiling 92. For this reason, similarly to the fall prevention furniture 1, the furniture 91 can be prevented from falling by causing a resistance moment to act against the lifting of the upper end portion 91 b of the rear direction 112 of the furniture 91. Furthermore, also in this fall prevention furniture 1a, the storage unit 10 can effectively use the space 93 between the furniture 91 and the ceiling 92 as a storage space. Further, the slide back plate 21 of the elevating unit 20 is set along the main body back plate 11 so that the elevating unit 20 does not protrude into the upper space 101 a of the storage unit 10. For this reason, the slide back plate 21 disposed along the main body back plate 11 is difficult to enter the field of view of the user who uses the fall-preventing furniture 1a and is not easily noticeable. Therefore, even in this fall-preventing furniture 1a, it is possible to provide a clean appearance (design) which does not cause a feeling of pressure to the user or is extremely small and does not obstruct the space 93a in the upper direction 101 of the storage unit 10.

  Furthermore, in the fall prevention furniture 1 a, the slide back plate 21 passes through the slit 12 b of the top plate 12 and is stored inside the storage unit 10. For this reason, unlike the fall prevention furniture 1, there is no need to attach the decorative material 17 that covers the slide back plate 21 from the left-right direction 120. Furthermore, since the elevating means 30 and the fixing means 40 are also housed in the housing unit 10, they do not enter the user's field of view in appearance, and the fall-preventing furniture 1 a having a clean and organized design as a whole can be provided.

  In addition, in the fall prevention furniture 1a of this example, since the slide back board 21 can be supported in the state adjusted to predetermined height with the raising / lowering means 30, it is also possible not to provide the fixing means 40. FIG. In this case, it is not necessary to provide the slit 22 in the slide back plate 21.

  FIG. 7 shows a state in which the fall prevention device 5 which is one of further different embodiments of the present invention is installed. The fall prevention device 5 contacts the slide back plate 21 that moves up and down along the back plate 91c constituting the back surface of the furniture 91, the fixing means 40 that fixes the slide back plate 21 to the back plate 91c, and the ceiling 92. The flat plate 25 is a flat plate 25 that is attached to the end portion 21a of the slide back plate 21 in the upward direction 101 at a substantially right angle. The slide back plate 21 is also provided with two slits (grooves) 22 for height adjustment extending from the end portion 21 b in the lower direction 102 in the upper direction 101. The fixing means 40 includes four plates 41 extending in the left-right direction 120 sandwiching the slide back plate 21 together with the back plate 91c from the rear direction 112, and four sets of connecting the plate 41 and the back plate 91c via the slits 22. A bolt 42 and a nut 43 are provided.

  In this way, when the space 93 between the furniture 91 and the ceiling 92 is narrow and the above-described anti-falling furniture 1 and 1a cannot be installed, the anti-tip device 5 can be directly attached to the furniture 91. . Also in the fall prevention device 5, the slide back plate 21 can be fixed to the back plate 91c in a state where the slide back plate 21 is slid in the upward direction 101 and the flat plate 25 is brought close to the ceiling 92. For this reason, similarly to the fall-preventing furniture 1 and 1a, a resistance moment that opposes the lifting of the upper end portion 91b in the rear direction 112 of the furniture 91 can act on the furniture 91, and the furniture 91 can be prevented from falling. Further, the slide back plate 21 is set along the back plate 91 c and the wall 94 so as not to protrude into the space 93 in the upward direction 101 of the furniture 91. For this reason, the slide back plate 21 arranged along the wall 94 is difficult to enter the user's field of view and is difficult to stand out. Therefore, this toppling prevention device 5 can also provide a clean appearance (design) that does not give the user a feeling of pressure or is extremely small, and that there is no obstruction in the space 93 in the upward direction 101 of the furniture 91.

  In addition, when the width of the furniture 91 in the left-right direction 120 is wide, the plurality of fall prevention devices 5 can be mounted side by side in the left-right direction 120.
