Description

  The present invention relates to a furniture overturn prevention device that is installed between the top surface of a furniture and the wall of the room or between the side of the furniture and the wall of the room. It is related to securing a high safety living space.

In order to prevent furniture from falling, there was an invention in which the upper surface of the furniture and the ceiling of the room were connected by an elastic member, or side plates extending from the floor to the ceiling were attached to both sides of the furniture to prevent the furniture from falling (For example, refer to Patent Documents 1, 2, and 3.)
However, even though these inventions are effective when the ceiling of the room has a sufficient strength, there is a problem that the ceiling is broken when the strength of the ceiling is weak, which is not useful.
Therefore, although it was considered to connect the furniture and the wall of the room with brackets, the board constituting the entire surface of the wall was weak and there was a problem that the furniture could not be supported even if a bracket was attached thereto.
A normal wall has a bone called a torso between the pillars to attach the board, and the torso is strong enough, so if you attach furniture to the torso, Although it is possible to prevent toppling, the torso is a member that extends horizontally and is attached at a pitch of about 300 mm above and below, so it is not possible to connect furniture to the torso by simply placing the torso depending on the position of the torso. In addition, there is a problem that the size of the bracket becomes excessive and the appearance looks bad.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a fall prevention device for fixing furniture so that it does not fall when an earthquake occurs.
In particular, a furniture fall prevention tool that can adjust the distance between the mounting positions and the posture relationship according to the positional relationship between the wall shell and the furniture, and is a cheap and simple furniture fall prevention tool that does not impair the beauty. Is to provide.

  To provide a base to be attached to the wall and a bracket to be attached to furniture, and to connect the base and the bracket so that they can be extended and contracted by a swing arm and an extension arm. Further, the attachment between the base and the swing arm and the attachment between the extension arm and the bracket are configured to be swingable.

According to the present invention, it is possible to provide a furniture overturn prevention device having a function of preventing the furniture from falling over when an earthquake occurs.
In particular, the space between the base attached to the wall and the bracket attached to the furniture can be freely adjusted, and the furniture can be attached to the base and bracket by shifting the vertical and horizontal positions. It is now possible to fix furniture that easily adapts to changes in the position of the edges and the situation of the furniture.
In addition, the present invention can prevent the furniture from falling down when an earthquake occurs, so that the safety of people living near large furniture has increased. Furthermore, it was possible to provide an inexpensive and simple furniture fall prevention tool having an aesthetic appearance.

A base, a swing arm having one end supported by the base so as to be swingable and having a screw rod, and a screw side screw portion at one end screwed into the screw rod The furniture has a fall prevention tool including an extension arm and a bracket that holds the other end of the extension arm in a swingable manner.
The base may be configured so that the swing arm is swingably held and attached to the wall. For example, if a mounting surface for mounting on a wall is provided and two or more holes for passing wood screws are provided on the mounting surface, the mounting surface can be mounted on the wall.
The base, the screw rod, the extension arm and the bracket are preferably made of iron, because the strength is so strong that it is possible to reduce the size of the fall-preventing tool and it is cheaper.
In the configuration in which the swing arm is swingably held by the base, there is a configuration in which a hole penetrating both the base and the swing arm is drilled and a pin is inserted to couple the swing arm without play. Also, there is a little play for each other, such as a structure in which an iron ring fixed to the base and an iron ring fixed to the swing arm are connected to each other through the other ring, or a combination of a neck hole stopper and a hole. Concatenated configurations are possible.
At this time, the two swing directions of the swing between the base and the swing arm and the swing between the extension arm and the bracket are configured to be swingable in substantially the same direction. Of course, both of them may be configured to be able to swing in any direction, but if they are configured to be able to swing in at least approximately the same direction, the relationship between the mounting posture of the base and the bracket can be adjusted in a two-dimensional plane. This is because it can be made possible.
The screw rod is a male screw, and preferably has a screw as close as possible to the swinging portion at one end, thereby increasing the range of adjustment of the distance between the base and the bracket. The extension arm is longer than the length of the screw rod, and a female screw of the same size as the screw rod is provided on one side.
Then, the other end of the extension arm is held swingably by the bracket. About the structure hold | maintained so that rocking is possible, the structure similar to the structure which hold | maintains a rocking | swiveling arm by the above-mentioned base may be sufficient. It is preferable to provide play in any one of the two locations that are configured to be swingable so as to be able to swing because various postures can be selected for the mounting posture.

A base, a swing arm having one end supported by the base so as to be swingable and having a screw rod, and a screw side screw portion at one end screwed into the screw rod An extension arm having an extension arm having a neck-side screw portion at the other end, and a neck hole stopper attached by screwing a set screw portion into the neck-side screw portion,
Further, a bracket having a neck hole that is larger than the neck portion of the neck hole stopper and smaller than the head portion of the neck hole stopper is provided, and the neck hole stopper is attached to the extension arm through the neck portion in the neck hole. Thus, the furniture is provided with a tip-over preventing tool for the furniture, in which the other end of the extension arm is swingably held by the bracket.
The present invention is a device in which the extension arm is attached to the bracket in the above-described device, in which the neck hole stopper and the hole are combined. Both a configuration in which the neck side screw portion of the extension arm is a female screw and the set screw portion for fixing the neck hole is a male screw, and a configuration in which the neck side screw portion is a male screw and the set screw portion is a female screw are conceivable.
Here, if the neck side surface of the head of the neck hole stopper has an outer surface shape that is substantially the same as a spherical band from which a part of the spherical surface is cut off, when the neck hole stopper swings, This is preferable because the oscillation is smooth.
By making the neck hole smaller than the outer diameter of the extension arm and the outer diameter of the head of the neck hole stopper, the bracket is prevented from being detached from the neck part of the neck hole stopper and the neck hole is larger than the outer diameter of the neck part. A hole. As long as the extension arm does not get stuck in the neck hole or the head of the neck hole stop does not come out from the neck hole, the neck hole is a long hole and the width of the long hole is the outside diameter of the extension arm or the outside of the head. If the width is smaller than the diameter, it is possible to make the elongated hole longer than the outer diameter of the extension arm or the outer diameter of the head.

Further, when the base mounting surface and the bracket mounting surface are configured to intersect at a substantially right angle, the swing arm and the extension arm can swing within a range of 0 to 37 degrees with respect to the bracket mounting surface. Use furniture to prevent falls.
In many cases, the wall to which the base is attached and the upper and side surfaces of the furniture intersect at right angles. Therefore, the mounting surface of the base and the mounting surface of the bracket are configured to intersect at a substantially right angle. The swing arm and extension arm can swing within the range of 0 to 37 degrees with respect to the mounting surface of the bracket. However, it can be attached.
The above-described furniture overturn prevention device is a furniture overturn prevention device having a rocking cylinder portion that covers the entire screw rod of the rocking arm.
The screw rod needs to be made of iron from the viewpoint of strength, but it looks bad as it is, and it is not appropriate to apply a coating from the viewpoint of maintaining the accuracy and strength of the screw. Therefore, the entire screw rod is covered with an oscillating cylinder having an inner diameter larger than that of the extension arm, and the extension arm is inserted into the oscillating cylinder so that the oscillating side screw is screwed onto the screw rod. Is.
The above-described furniture overturn prevention device, wherein the distance from the swinging part at one end of the swinging arm to the swinging part at the other end of the extension arm can be adjusted within a range of 300 to 500 mm. To prevent furniture from falling.
Since the wall shell is attached to the pillar at a pitch of about 300 mm in the vertical direction, when the bracket is attached to the upper surface of the furniture, the height from the bracket mounting surface to the swinging part of the swinging arm is a maximum of 300 mm. Sometimes. At this time, if the extension arm is attached so as to be 37 degrees with respect to the mounting surface of the bracket, the length from the swinging part at one end of the swinging arm to the swinging part at the other end of the extension arm is about 500 mm long. Because it will be. Moreover, it is because it is thought that the length below 300 mm is unnecessary in practical use.

A first embodiment of the present invention will be described below with reference to FIGS. The fall prevention tool 1 according to the first embodiment includes a base 4, a swing arm 5 that is swingably held by the base 4, and a screw side screw portion 6 a at one end of a screw rod 5 b of the swing arm 5.

The neck hole stopper 7 is made of iron and has a head portion 7a, a neck portion 7b, and a set screw portion 7c. The head portion 7a has an outer diameter of 15 mm, and the neck side surface 7d has an outer surface shape of a substantially spherical band. did. The neck 7b was 6 mm in outer diameter x 8 mm in length, and the set screw 7c was an M6 male screw. For this reason, when the set screw portion 7c for fixing the neck hole is completely screwed into the neck side screw portion 6c of the extension arm, a neck portion having an outer diameter of 6 mm and a length of 8 mm is formed.
The bracket 8 was formed by bending a flat steel having a thickness of 1.9 mm into an L shape, and having one side as a holding surface 8c for attaching to the neck hole stopper 7 and the other as an attaching surface 8a for attaching to furniture. A neck hole 8b having a hole diameter of 10 mm was provided on the holding surface 8c.

In the fall prevention tool 1 of the first embodiment, when the swaying side screw portion 6a of the extension arm is screwed to the root of the screw rod 5b, the swaying end 6d of the extension arm is positioned 15 mm from the center of the pin 9, and the screw of the screw rod When the swaying side screw portion 6a of the extension arm is screwed in the vicinity of the end 5c, the swaying side end 6d of the extension arm is positioned 223 mm from the center of the pin 9.
Since the length of the neck portion 7b of the neck hole stop is 8mm with respect to the thickness 1.9mm of the holding surface 8c of the bracket, there is play of 6.1mm, but the bracket 8 is separated by 3mm from the neck side end 6e of the extension arm. , The distance A from the center of the pin 9 which is one of the swing centers to the holding surface 8c of the bracket which is the other swing center can be freely adjusted within a range of 298 to 506 mm. .
The neck 7b has an outer diameter of 6 mm and a length of 8 mm with respect to the neck hole 8b having a thickness of 1.9 mm and a hole diameter of 10 mm, and the neck side surface 7d of the head has a substantially spherical outer surface shape. Therefore, the angle B of the extension arm 6 with respect to the mounting surface 8a of the bracket can be inclined up to 40 degrees.
Also, all the outer surfaces of the swing arm 5, the extension arm 6, the neck hole stopper 7, the bracket 8 and the pin 9 except for the base 4 and the screw rod 5b are painted to have an aesthetic appearance. The screw rod 5b is not painted from the viewpoint of maintaining the accuracy and strength of the screw, but the screw rod 5b is covered with the swinging cylinder portion 5d so that it is not noticeable to the human eye, and the aesthetics of the entire fall prevention device 1 is obtained. Can be maintained.

In a normal wall, a cylinder head 2b having a thickness of 16 mm and a width of 42 mm is attached to the indoor side of the pillar 2a at a pitch of 300 mm, a gypsum board 2c is attached to the indoor side of the trunk 2b, and a cloth 2d is attached to the surface of the gypsum board 2c. There are many cases to stretch.
The gypsum board 2c is weak in strength, but the torso 2b has sufficient strength to prevent the furniture 3 from falling over, so the base 4 of the fall prevention tool 1 is sandwiched between the gypsum board 2c and the cloth 2d. Attach to tab 2b. Further, the bracket 8 is attached to the furniture 3.
Since the mounting surface 4a of the base and the mounting surface 8a of the bracket are each provided with a mounting hole, the screw of the wood screw 10 is screwed into the trunk 2b through the mounting hole, and the wood screw 10 is passed through the mounting hole. By screwing into the furniture 3, the base 4 is attached to the wall and the bracket 8 is attached to the upper surface of the furniture 3.
Since the trunk 2b has a pitch of 300 mm, it is considered that the height C from the upper surface of the furniture 3 to the trunk 2b is 300 mm when the conditions are the worst. At this time, when the angle θ between the fall prevention tool 1 and the upper surface of the furniture 3 is set to 37 degrees, the distance between the center of the pin 9 and the intersection of the bracket holding surface 8c and the center of the neck portion 7b of the neck hole stop is as follows. It becomes 500 mm, and the fall prevention tool 1 can be attached.
In addition, since the fall prevention tool 1 of the first embodiment is configured to allow play in the relationship between the neck hole stopper 7 and the holding surface 8c of the bracket and swing in all directions, the bracket 8 is attached to the side surface of the furniture. Even if there is a vertical displacement in the position where the wall shell 2b and the bracket 8 are attached, it can be easily attached.
