Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a magnetic catch, and more particularly to a magnetic catch that can be easily unlocked by pressing a push button.

(Background Art) Generally, in a magnetic catch, a magnet with a strong attraction force is required in order to reliably maintain the closed position of the door, but this strong attraction force becomes a hindrance when the door is opened. Therefore, a light-touch magnetic catch is used at the expense of the closing force of the normal door.

(Purpose of the invention) Therefore, the present invention uses a magnet with strong adsorption force, and when the push button formed on the front of the door is pressed, the iron piece adsorbed by the magnet tilts due to the force of the spring. The main purpose of this invention is to provide a unique magnetic catch in which the adhesion with the magnet is released and the door can be opened naturally by the force of the spring without using the handle. .

(Disclosure of the invention) The details of the invention will be described below based on an embodiment shown in the drawings.

In the figure, number 1 is an iron piece that is attracted to a magnet 3 attached to the furniture body 2, and is tiltable to the frame 5 by a set angle, preferably 30 degrees, using a pivot 4 formed at one end as a fulcrum. The frame 5 is attached to the back side of the door 6. The iron piece 1 is constantly pressed in a tilting direction by a spring 9. Reference number 7 is a stopper that holds the iron piece 1 in a position parallel to the door. 8 is provided on the frame 5, and the stopper further includes an inclined guide surface 7A that contacts the free end of the iron piece 1 and rotates backward when the iron piece 1 returns from an inclined position to a parallel position. We are prepared. Reference number 10 is a push button provided on the front side of the door, and is constantly pressed in the projecting direction by a spring 11, and the rear end of the push button passes through the door and is attached to the rear surface of the stopper 7. is in contact with. When the push button 10 is pressed, the stopper 7 rotates counterclockwise and disengages from the iron piece.

In the state shown in FIG. 1, the iron piece 1 is attracted to the magnet 3 and the door is closed. When the push button 10 is pressed from this state, the engagement by the stopper 7 is released and the iron piece 1 is tilted by the force of the spring 9. (See Figures 2 and 3).

Due to this tilting movement, the attraction between the magnet 3 and the iron piece 1 is released, and the door 6 is biased in the opening direction and opened naturally. In general, the attraction force of a magnet is strong in the direction perpendicular to the attraction surface, but it decreases significantly in the tangential direction. The iron piece 1 can be easily separated from the magnet 3. Further, it is preferable to use a relatively strong spring 9 of the iron piece 1.

(Effects of the present invention) As described in detail above, according to the present invention, simply by pressing and releasing the push button, the stopper that engages the iron piece is released and the iron piece is tilted by the force of the spring. When the adhesion with the magnet is released, the door can be released naturally without using the handle due to the force of the spring, and the iron piece tilts against the magnet adsorption surface and comes off, creating a strong adsorption force. You can easily remove the iron piece from the magnet by using a magnet with a
This has the effect of ensuring that the door is kept in a closed position.

Claims (1)

[Scope of utility model registration request] An iron piece to be attracted by the magnet is formed on the back of the door so that it can tilt around a pivot formed at one end thereof, a spring is provided to constantly press the iron piece in the direction of inclination, and the iron piece is held parallel to the door. A stopper is provided for holding the iron piece in the position, and the stopper has an inclined guide surface that abuts against the free end of the iron piece and retreats when the iron piece returns from the inclined position to the parallel position, and further includes a stopper on the front surface of the door that is always directed toward the protruding direction. A magnetic catch in which a push button and a stopper are interlocked and connected so that when the push button receives elasticity and is pressed, the stopper is moved back from a position where the iron piece is engaged to a position where it is released.
