Description

  The present invention relates to an overturn prevention device for preventing furniture such as a bookshelf, a cabinet or a desk, a refrigerator, a piano, various furniture, or various devices from falling due to vibration caused by an earthquake or the like.

  Conventionally, appliances that prevent falls such as household cupboards, bookshelves, storage furniture such as clothes dance, refrigerators or pianos, office cabinets and desks, and open shelves and various equipment in factories, etc. have been proposed. .

  For example, “Tokyo Fire Department Digital Library” disclosed in Non-Patent Document 1 “Workplace earthquake countermeasures (issued in August 2008) (http://www.tfd.metro.tokyo.jp/hp-sidouka/ 2008-2350-3 /) "Countermeasures for preventing fall / fall of office furniture" discloses a method for fixing a ceiling surface and a wall surface of a cabinet or the like with an L-shaped bracket using screws or the like. .

  Moreover, in the spring-type turnbuckle disclosed in Patent Document 1, a turn-preventing bracket is attached to the ceiling surface of the furniture and the wall surface of the room with nails or screws, and a turn spring body is provided between the tip-preventing bracket. A structure for hanging a buckle is disclosed.

  Moreover, in the earthquake-proof furniture overturn prevention tool disclosed in Patent Document 2, a structure in which one of T-shaped members is attached to a wall surface and the other is attached to furniture with an adhesive material or the like is disclosed.

  Tokyo Fire Department Digital Library Workplace earthquake countermeasures (issued in August 2008)   Japanese Patent Laid-Open No. 2002-248023   JP 2005-224562 A

  However, in the L-shaped metal fitting disclosed in Non-Patent Document 1, there is a possibility that a nail or a screw that stops the L-shaped metal fitting may be removed due to vibration such as an earthquake. In particular, in current general houses and office offices, fire walls such as plasterboard must be used for the walls, and nails and screws may be easily removed.

  In order to solve such a problem of the L-shaped metal fitting, the spring-type turnbuckle disclosed in Patent Document 1 uses a spring to provide a buffering function that relaxes the load transmitted to the fall-preventing metal fitting. However, this buffer function is intended to increase the time during which the so-called impact force, which is an instantaneous load, is applied, and not to reduce the load transmitted to the metal fitting for overturning. It was not enough to prevent the nails and screws used for easy wall surfaces from coming off.

  In addition, since the anti-seismic furniture overturn prevention device disclosed in Patent Document 2 receives a load on an adhesive surface having a predetermined area as disclosed, the wall surface is broken rather than an L-shaped bracket fastened with a nail or a screw. Is less likely. However, in various experiments by the applicant, if a strong adhesive tape or the like is used to reliably prevent a fixture or the like that is to be prevented from falling, the gypsum board may be destroyed. In addition, even when the gypsum board is not destroyed, the strength of the paper or resin wallpaper affixed to the surface is very low, or the adhesive strength of the glue used when pasting the wallpaper is low As a result, the wallpaper may be peeled off from the plasterboard.

FIG. 2 is a diagram illustrating an example of an installation method of the fall prevention tool 10. FIG. 3 is a diagram illustrating an example of a fall prevention state of various fixtures. FIG. 4 is a diagram illustrating another example of the installation method of the fall prevention tool. FIG. 5 is a diagram illustrating an example of a fixing portion of the fall prevention tool 10.

  The fall prevention device 10 of the present invention includes household furniture such as cupboards, bookshelves, clothes dance, refrigerators or pianos, various cabinets and desks in offices, and various furniture 100 such as open shelves and various devices in factories. Used for.

  The fall prevention tool 10 includes a first fixing portion 20 having a first bonding portion 21 that is bonded and fixed to a wall surface 120 on one surface, and a second bonding portion that is bonded and fixed to the surface of various fixtures 100 on one surface. A second fixing portion 40 provided with 41, a first locking portion 24 provided on the other surface of the first fixing portion 20, and a second locking provided on the other surface of the second fixing portion 40. A rubber belt 60 as an elastic member spanning the portion 44 is roughly provided.

  The first locking portion 24 includes two standing portions 25 that are erected on the other surface of the first fixing portion 20, and a hook that is spanned between the end portions of the two standing portions 25. And a transfer unit 26. One end 63 of the rubber belt 60 is inserted into an insertion hole 27 formed by the two standing portions 25, the spanning portion 26, and the other surface of the first fixing portion 20.

  Similarly, the second locking portion 44 is spanned between two standing portions 45 erected on the other surface of the second fixing portion 40 and end portions of the two erected portions 45. It is comprised from the spanning part 46. The other end side 64 of the rubber belt 60 is inserted into an insertion hole 47 formed by the two standing portions 45, the spanning portion 46, and the other surface of the second fixing portion 40.

  The rubber belt 60 can be any material such as natural rubber or synthetic rubber as long as the material and type satisfy the function of preventing various types of furniture from falling. Similarly, the shape may be a belt-like shape shown in FIG. 1, and there is no problem with a shaft-like body or a square-shaped body. The rubber belt 60 is inserted into a rubber belt main body 62 for expanding and contracting as an elastic member, one end side 62 inserted into one insertion hole 27 at both ends of the rubber belt main body 62, and the insertion hole 47 at the other end. And the other end 64 side.

  In addition, one end side wall portion 65 that abuts the spanning portion 26 is provided on the end of the one end side 63 on the rubber belt main body 62 side. An end side inclined portion 67 is provided. Similarly, the other end side wall portion 66 is provided on the other end side 64 at the end of the rubber belt main body 62 so as to come into contact with the spanning portion 46. From the other end side wall portion 66 toward the end portion. The other end side inclined portion 68 is provided.

  Since the one end side 62 and the other end side 64 have such a shape, vibrations such as earthquakes occur in the various fixtures 100 in a state where the fall prevention device 10 is stretched between the various fixtures 100 and the wall surface 120. Even when the one end side wall portion 65 acts, the one end side wall portion 65 abuts on the spanning portion 26 and the other end side wall portion 66 abuts on the spanning portion 46, so that the both end portions are not detached from the respective fixing portions. .

  The one end side inclined portion 67 and the other end side inclined portion 68 are inclined portions for smoothly passing through the insertion hole 27 and the insertion hole 47, respectively.

  The one end side 62 and the other end side 64 have the above-described structure, but are not limited to this configuration. For example, the shape of the entire rubber belt 60 is changed to the shape of the belt main body 62. The belt shape may be extended. In the case of this shape, as shown in FIG. 5, the rubber belt 60 is inserted into the insertion holes 27 and 47, and then folded toward the belt main body 62 and inserted into the insertion hole. It is good also as a structure fixed to each fixing | fixed part by pinching | interposing using the U-shaped member 29 which pinches | interposes all of the spanning part 26 and the folded back rubber belt.

  Further, in this embodiment, the rubber belt 60 as the elastic member has been described. However, it is needless to say that, for example, a spring or other material / member can be used as long as it is a member that expands and contracts by a load.

  The usage method of the fall prevention tool 10 of the present invention having the above configuration will be described below.

  FIG. 2 is a view showing a state in which two fall prevention tools 11 and 12 are attached to a cabinet 102 as various fixtures 100. The cabinet 102 is placed on the floor surface 122 so that the back surface is in contact with the wall surface 120.

  In the two fall prevention devices 11 and 12, each first fixing portion 20 is bonded and fixed to the wall surface 120 via the first bonding portion 21, and the second fixing portion 40 fixes the second bonding portion 41. To the ceiling surface 104 of the cabinet 102.

The first adhesive portion 21 and the second adhesive portion 41 are made of, for example, an acrylic foam as a base material, an acrylic adhesive material on both surfaces thereof, and a bonding tape (so-called double-sided tape) having a tensile strength of 120 N / cm ^2. It is used. In addition, the 1st adhesion part 21 adhere | attached on a wall surface may use the joining tape which adhere | attaches reliably on an uneven | corrugated wallpaper, for example by having thickness and a softness | flexibility to a base material.

  When vibration such as an earthquake acts on the cabinet 102 with the two anti-tip devices 11 and 12 attached as shown in FIG. 2, generally the direction parallel to the short side of the bottom surface of the cabinet 102 (on the paper surface in FIG. 2). It will swing in the vertical direction). As a result, the cabinet 102 swings in a direction away from the wall surface 120, and is hung between the first fixture 20 bonded and fixed to the wall surface 120 and the second fixture 40 bonded and fixed to the ceiling surface 104. The passed rubber belt 60 expands and contracts as the cabinet 102 swings.

  The expansion and contraction of the rubber belt 60 reduces the momentum of the cabinet 102 due to the acceleration of the earthquake, and as a result, the force (striking force) acting on the first fixture 20 and the second fixture 40 is reduced.

  The non-stretchable belt was used in place of the rubber belt 60 in the test that reproduced the maximum acceleration (818 gal (north-south direction)) at the time of the Great Hanshin-Awaji Earthquake on the three-dimensional shaking table of the UR Urban Research Institute of Technology. In some cases, the plasterboard as a wall surface may be destroyed or the wallpaper affixed to the surface of the plasterboard may be damaged. However, when the rubber belt 60 is used, such destruction or damage is observed. There wasn't.

  When the first fixing member 20 is fixed to the wall surface 120, when the nail or the screw is used instead of the first bonding portion 21, the above-described three-dimensional structure is also obtained even when the rubber belt 60 is used as an elastic member. In the shaking table test and other tests, the wall surface 120 was broken or damaged. As described above, the first fixing tool 20 is fixed to the wall surface 120 through the first bonding portion 21, and an elastic member is provided between the first fixing tool 20 and the second fixing tool 40. It has been confirmed that the configuration of hanging has a high effect in preventing the fall of various fixtures.

  The second fixing portion 40 has been described as being bonded and fixed to the ceiling surface 104 via the second bonding portion 41 provided on one surface thereof, but it is possible to use fixing with a nail or a screw. However, if it is an office fixture or the like that does not come off due to the vibration of the earthquake and can be damaged by this nail or screw, the second fixing portion 40 is fixed without using the second adhesive portion 41. Also good.

  FIG. 3 is a view of the cabinet 102 as seen from a direction parallel to the surface of the wall surface 120, and shows the state of the cabinet 102 that rarely occurs due to various conditions in the above-described tests on the three-dimensional shaking table and other tests. ing.

  When the earthquake vibration is very large, for example, with a seismic intensity of 6 or higher, the cabinet 102 may move in parallel against the static frictional force or dynamic frictional force of the floor 122 due to the earthquake force (acceleration). When the cabinet 102 is translated so as to slide on the floor surface in the direction away from the wall surface 120, the fall prevention tool 12 spanned between the wall surface 120 and the ceiling surface 104 causes the ceiling surface 104 side of the cabinet 102 to be As shown in FIG. 3, it may be in a state of falling over toward the wall surface 120.

  In particular, since the overturn prevention device 10 of the present invention is spanned between two fixing devices by a rubber belt 60 that is an elastic member, when it receives a very large vibration, it moves in parallel from the wall surface 120, and this figure. 3 may occur. (Of course, in the case of a non-stretchable belt, the wall surface 120 is destroyed or damaged before this state is reached, and the cabinet 102 falls down.) This state of FIG. There is no need to prevent as much as possible.

  FIG. 4 is a diagram showing attachment of the two fall prevention tools 11 and 13 to the cabinet 102 for preventing the state of FIG. As in FIG. 2, the cabinet 102 is placed on the floor surface 122 so as to contact the wall surface 120.

  In the fall prevention tool 11, the first fixing portion 20 is bonded and fixed to the wall surface 120 via the first bonding portion 21, and the second fixing portion 40 is bonded to the ceiling surface 104 via the second bonding portion 41. It is fixed. In FIG. 4, the overturn prevention tool 11 is arranged on the right side of the page, but it may be on the left side of the page or the approximate center of the ceiling. A plurality of them may be provided.

  The fall prevention tool 13 is bonded and fixed between a position separated from the ceiling surface 104 by a predetermined distance in the height direction of the cabinet 102 and the wall surface. In FIG. 4, the position is a substantially center of gravity position of the one side surface 106 of the cabinet 102.

  In the state of FIG. 3, the ceiling surface 104 is fixed to the wall surface 120 via the fall-prevention device 12 when the cabinet 102 is translated so as to slide on the floor surface in a direction away from the wall surface 120 due to very large vibration. Therefore, it is considered that this occurs because the cabinet 102 swings around the second fixed portion 40 as a fulcrum.

  In the attachment of the fall prevention tools 11 and 13 shown in FIG. 4, the fall prevention tool 13 restricts swinging with the second fixing portion 40 of the fall prevention tool 11 as a fulcrum, so that the cabinet 102 shown in FIG. The situation where it falls to the side does not occur.

  It should be noted that the attachment position of the fall prevention tool 13 to the one side surface 106 is effective as long as it is separated from the ceiling surface 104 to some extent, but as shown in FIG. effective. In addition, in FIG. 4, although the fall prevention tool 13 is only one piece, you may provide multiple.

  As described above, according to the present invention, since an adhesive-fixed fixture is used, it is possible to provide a fixture for preventing the overturn of various fixtures that can be easily attached to various fixtures and can be manufactured at a low cost.

  In addition, a fixture for adhesive fixing using a bonding tape is easy to remove due to the rotational force in a plane parallel to the adhesive surface, and provides a tipping prevention tool that facilitates movement of various fixtures when rearranging indoors. Is possible.

  Further, as described in detail above, it is possible to provide a tipping prevention tool that reliably prevents tipping of various types of furniture.
