Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention aims to prevent furniture such as chests of drawers and sideboards from falling over due to vibrations such as earthquakes. This invention relates to a furniture tipping prevention fitting that is fixed to a fixed part.

[Conventional technology]

If furniture such as chests of drawers or sideboards topples due to earthquakes or other vibrations, it not only poses a danger to people, but also scatters the items stored inside the furniture, impeding evacuation. In some cases, human lives may be affected. Additionally, if the furniture falls onto a stove, iron, etc. that is in use, a fire may occur.

Conventionally, therefore, as a safety measure, furniture has been fixed to pillars, walls, etc. of houses using furniture fall prevention fittings to prevent them from falling over.

For example, as shown in FIG. 6, a piece of metal piece 1 in the shape of a band is formed by bending a furniture fall prevention fitting into a substantially L-shape, and one piece 1a of the metal piece 1 is attached to the piece of furniture 2.
Fix it to the rear end of the top surface 2a with screws 3, etc., and
b is fixed to the pillars (or lintels) 4 of a house with screws 5, etc., or as shown in Fig. 7, the furniture fall prevention fitting is fixed to a linear fitting main body 6.
and fixing fittings 7a and 7b rotatably pivoted to both ends of the fitting main body 6, one of the fixing fittings 7
A is fixed to the rear end of the upper surface 2a of the furniture 2 with screws 3, etc., and the other fixing fitting 7b is fixed to the lintel 8 (or pillar) of a house with screws 5, etc. There is.

[Problem that the invention seeks to solve]

However, in these conventional methods, when the furniture fall prevention bracket is directly fixed to both the furniture and the pillar as shown in Fig. 6, the mounting position and mounting direction are limited. eye,
After deciding where to install the furniture, place the furniture, pillars, walls,
Depending on the situation with the fixed part such as the ceiling, it is necessary to decide whether to mount the furniture vertically or horizontally, and to use the appropriate fittings to prevent furniture from tipping over. There is the inconvenience of having to use . In addition, since the furniture fall prevention fitting is directly fixed to the furniture and the fixed part such as a pillar with screws or the like, the load due to vibration is applied directly to the fixed part. Therefore, the vibration loosens the screws and makes them easier to pull out, especially when the furniture 2 is shaken in the longitudinal direction and a toppling moment in the F direction is applied to the screws 5 fixed to the pillars 4, which are the fixed parts. There is a problem in that a lever force is applied using the O point of the part as a fulcrum, and the screw 5 comes out with a small force.

In addition, in the case shown in Fig. 7, the fixing fittings are pivotally attached to both ends of the fitting body, so the mounting position of the fixing fittings can be adjusted, and the lateral position relative to the front and back direction of the furniture can be adjusted. It can absorb shaking and vertical shaking, but vibrations caused by earthquakes
There are a wide variety of directions such as vertical, horizontal, diagonal, etc.
Moreover, since the furniture overturn prevention metal fitting generates complex vibrations that combine these vibrations, it is not possible to absorb vibrations other than those described above, that is, horizontal vibrations of the furniture in the lateral direction and vibrations in the diagonal direction. Therefore, even in the furniture toppling prevention fitting, there is a risk that the screws may loosen due to earthquake vibrations and come off.

The present invention has been made in view of the above-mentioned conventional problems, and is capable of following vibrations in all directions, such as vertical, horizontal, diagonal, and complex shaking that is a combination of these. The object of the present invention is to provide a furniture toppling prevention fitting whose mounting position can be easily adjusted.

[Means for solving problems]

To this end, the present invention provides a furniture fall prevention fitting in which a base fitting is provided on the top of a fixing fitting that is fixed to the upper surface of furniture such as a chest of drawers or a sideboard, and an elastic material is provided between the fixing fitting and the base fitting. Intervened,
A base metal fitting is supported at a predetermined distance above the fixed metal fitting so as to be vertically movable and swingable, and a bracket is provided on the base metal fitting,
One end of the arm fitting is rotatably attached to the bracket via a pivot pin, and the other end of the arm fitting is movably attached to a part of the house, such as a pillar or wall, via a mounting fitting. This structure achieves the intended purpose.

[Effect]

This configuration allows the furniture to shake due to earthquake vibrations, etc.
Even when the fixing metal fittings work together, the base metal fitting is supported by the fixed metal fitting through an elastic material so as to be able to move up and down and swing freely, and the base metal fitting and the fixed part are connected to an arm whose both ends are rotatable. Rotatable with metal fittings,
Since they are movably connected, the base metal fittings are free to tilt in any direction in response to the movement of the fixed metal fittings. Furthermore, even if the furniture moves up and down, the up and down movement is absorbed by the expansion and contraction of the elastic material and the rotation of the arm fittings. Therefore, no load is applied to the screws fixing the fixing metal fittings or the fixing piece, and therefore the screws do not come off.

〔Example〕

The present invention will be described below with reference to illustrative embodiments.

Furthermore, in the embodiment, the fixing metal fitting 11 and the base metal fitting 12
are connected by a connecting pin 18, but the connecting pin 18 can be omitted by fixing the lower end of the elastic material to the upper horizontal surface 11b of the fixing metal fitting 11 and the upper end of the elastic material to the lower surface of the horizontal surface 12a of the base metal fitting 12. Can be done.

The arm fitting 13 consists of a band-shaped plate whose both ends are bent into an arc shape in the same direction, and reinforcing flanges 13a are formed on both longitudinal edges thereof. The reinforcing flange 13 is attached to one end of the arm fitting 13.
A mounting flange 13b is formed extending from a, and a pivot pin 21 is rotatably fitted into the flange 13b. Both ends of the pivot pin 21 are fitted into brackets 12b erected on the horizontal surface 12a of the base metal fitting 12. Therefore,
One end of the arm fitting 13 is rotatably attached to the base fitting 12 via a pivot pin 21. Further, a mounting hole 23 having a diameter larger than the bolt diameter of the mounting bolt 22 and smaller in diameter than the head 22a of the mounting bolt 22 is bored at the other end of the arm fitting 13. .

Reference numeral 24 denotes a mounting fitting for attaching the other end of the arm fitting 13 to the attached part A of the house such as a pillar or lintel. is drilled. Further, the center part of the mounting bracket 24 is raised up in a substantially rectangular shape, and the upper surface thereof is curved in an arc so as to be approximately concentric with the bent part of the other end of the arm bracket 13. An engaging recess 26 is formed, and a bolt hole 27 is bored in the center of the engaging recess 26.
