Abstract

PURPOSE: To prevent a door from opening even at earthquake time not less than seismic intensity 6 by making force to close a door of a hinge having a spring and attracting force of a magnet catch fixed to a main body on the opening end side of the door act as jointly using opening preventive force. CONSTITUTION: A door 61 of a hinged door is fixed to a main body 91 such as furniture and a house by a hinge 30 having a spring, and force F to close the door 61 is generated. On the other hand, a magnet catch 40 is fixed to the main body 91 on the opening end side of the door 61, and attracting force G is generated between it and a magnetic substance plate installed on the door 61. Even at earthquake time not less than seismic intensity 6, the total of the closing force F of the hinge 30 having a spring and the attracting force G of the magnet catch 40 acts as jointly using opening preventive force, and opening of the door 61 can be prevented. In the door 61 having a vertical length not more than 90cm, the jointly using opening preventive force is set not less than about 3.5kg, and preferably, it is set not less than about 4kg, and much preferably, it is set not less than about 4.5kg or about 5kg, and in the case of the door 61 having a vertical length not less than 90cm, it is preferable to be set not less than about 6kg.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing the opening of a hinged door which prevents the hinged door from being opened during an earthquake or the like.

[0002]

2. Description of the Related Art Conventionally, a method of preventing the opening of a hinged door for preventing the hinged door from being opened in the event of an earthquake has not been developed.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for preventing the opening of a hinged door, which solves the above-mentioned conventional problems and prevents the hinged door from being opened during an earthquake or the like.

[0004]

In order to achieve the above object, the present invention provides a combined opening prevention force of a hinge with a spring and a magnet catch of about 3.
It proposes a method for preventing the opening of the hinged door, which is set to 5 kg or more.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for preventing the opening of a hinged door according to the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a hinge with a spring (30) used in the method for preventing the hinged door from opening according to the present invention. The hinge with a spring (30) includes a hinge body (31) and a door mounting piece (3).
The door mounting piece (32) generates a force F for closing the door (61) (see FIG. 2) by a built-in spring (not shown) of 2), which is known per se. The spring hinge (30) is fixed to the main body (91) of furniture, house, etc. at the hinge main body (31) as shown in FIG. The side end portion of the door (61) is fixed to the door mounting piece (32) and has a closing force F to support the door (61).
Next, a magnet catch (40) is similarly fixed to (91) on the body of furniture, a house, or the like. The magnet catch (40) has a force G for closing the door (61) by the attractive force of the magnet.

[0006] The closing force F of the above hinge with spring (30)
And the combined closing force G of the magnetic catch (40), the combined opening prevention force (the opening force that is the pulling force when viewed from the user side) (the pulling force at the normal position) is about 3.5 kg or more (preferably About 4 kg or more) (more preferably about 4.5)
Kg or more) (more preferably about 5 Kg or more).
As a result, it is possible to prevent the opening of the hinged door (61) in most cases even in an earthquake with a seismic intensity of 6 or more, which is the minimum required for disaster prevention. When the combined opening prevention force is less than about 3.5 kg, in most cases the seismic intensity is 6 and the hinged door (6
It cannot prevent the opening of 1). This means that in the Great Hanshin Earthquake on January 17, 1995, the cupboard of the inventor's own house (the combined opening prevention power was less than about 3.5 Kg, which was about 2 Kg) was opened at seismic intensity 6 and the dishes fell and scattered. It is known from the fact of the disaster.

A large magnet or a rare earth magnet may be used as a method for increasing the attraction of the magnet of the magnet catch (40). As another method, there is a method in which a plurality of magnets are arranged side by side or vertically stacked to increase the attractive force of the magnets. Finally, in the method of the present invention, not the attraction force of the magnet of the magnet catch (40) itself but the closing force F of the spring hinge (30) and the magnet catch (4).
It is confirmed that the combined opening prevention force, which is the sum of the closing force G of 0), is important.

Next, the above description is based on the assumption that the door (61) has a vertical length smaller than 90 cm (for example, about 45 cm, 60 cm, etc.) which is a normal length for a cupboard. Therefore, as a matter of course, when the vertical length of the door (61) is 90 cm or more (however, it is common to use furniture as a maximum of about 1.8 m to 2 m or less), the door (6
1) The force associated with its own mass is large and the stored items are
The force that collides with 1) and pushes it also becomes large. In this case, the combined opening prevention force, which is the sum of the closing force F of the spring hinge (30) and the closing force G of the magnet catch (40), is about 3.5 kg or more (desirably about 4 kg or more).
(More desirably, about 4.5 Kg or more) (More desirably, about 5 Kg or more) It is desirable that the force is greater than or equal to about 6 Kg or more. The force of about 6 kg or more corresponds to a force in which the closing force F of the spring hinge (30) is substantially the same and the closing force G of the magnet catch (40) is doubled. Next, the above explanation was about "furniture, housing, etc.", but especially in the case of furniture, if the furniture is fixed to the housing, the opening of the door (61) at seismic intensity 6 is further prevented. You can

The embodiments of the method for preventing the opening of the hinged door of the present invention are as described above, and the effects thereof are listed below. (1) According to the method of preventing the opening of the hinged door of the present invention, the combined use of the spring hinge and the magnetic catch has an opening prevention force of about 3.5K.
Since it is over g, it is possible to prevent the opening of the hinged door in the event of an earthquake. (2) The method for preventing the opening of the hinged door of the present invention has a combined opening prevention force of the hinge with the spring and the magnetic catch of about 3.5K.
Since it is g or more, it is possible to prevent the opening of the hinged door in most cases even in the case of an earthquake with a seismic intensity of 6 or more, which is the minimum required for disaster prevention.
