The present invention relates to a device that can securely open and close the door using a magnet and a push button.

In the present invention, the principle that the door is opened and closed by the difference in stroke, that is, the stroke, between the magnet and the pushbutton is used.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 (a) and 2 (b) show briefly the structure and the opening and closing principle of the opening and closing device of the present invention in the open and closed states, respectively. In the opening and closing device of the present invention, a magnet button 2 is installed between two push buttons 1 and 1 'located at both sides of the rear of the door. The push buttons 1, 1 'are supported in place by the support 3, and the support 3 is supported with the push button springs 4, 4' and the magnet button spring 4 "together. A spring support plate 5. These springs are enclosed within push buttons 1, 1 'and magnet button 2. In each button, a guide plate 6 is fixed to the support 3, In the guide plate 6, a guide plate pusher 7 is provided which is integrally fixed to the main body of each button, and in front of the buttons is a door D whose surface is made of an iron plate 8.

The guide plate 6 is well illustrated in FIG. 2. In the drawings, A, B, C, D, E, F and A represent the relative positions and heights of the grooves that are caught when the guide plate nipple 7 formed on the guide plate 6 moves.

The structure of the pusher 7 of the guide plate 6 is as shown in FIG. Since the pusher 7 is circumferentially fixed to the lower end of the other end of the leaf spring 9, one end of which is fixed to the guide plate 6 fixed to the support 3, pushbuttons 1 and 1 ' And the magnet button (2) are pressed.

In the present invention in which such a configuration is completed, the pushbuttons 1, 1 'and the magnet button 2 make the forward-reverse movement in the direction of the arrow in FIG. Push buttons 1 and 1 'are in the state shown in FIG. 1 (b), i.e., in the closed position and back to the state shown in FIG. ", And the distance is represented by" L "as shown in FIG. 1 (b). In the same stroke, the stroke in which the magnet button 2 has moved is indicated by "L". When the push button (1) (1 ') is shifted from the first (a) to the first (b) degrees, the pusher (7) is fixed, but it is as if in Fig. 2 A≥B≥C≥ It is as if it moved to D, and it will be in the same state as 1st (b) degree eventually. At this time, the magnet button 2 is moved in the left and right directions according to the movement of the support 3, which is also a movement by the guide plate 6 and the pusher 7. The guide plate 6 always tries to move to the left according to the action of the springs 4, 4 ′, 4 ″ fixed to the support plate 5.

In Figure 1, door D is on the right ( In the table direction) (state of FIG. 1 (b)). Door D is closed because it is attached to the magnet button (2). When opening the door D, push it again to the right by D ', E' in the second (a) degree, and the presser 7 moves from D 'to E' and moves further along E → F → A, It will be in a state (state of FIG. 1 (a)). At this time, since the stroke " L " of the push buttons 1 and 1 'is longer than the stroke " l " of the magnet button 2, the door D attached to the magnet falls and the closed state is released. The strokes "L" and "L" can be appropriately selected according to the weight of the door and the strength of the magnet.

Claims (1)

A magnet button 2 is provided between two push buttons 1 and 1 'positioned on both sides of the rear of the door D, and these buttons are positioned in position by the support 3, and the support stand One side of (3) is supported by a push button spring (4), (4 ') and a magnet button spring (4 ") that is stored inside each of the support plate, the back side of the support plate is formed with a pressing nipple (7) A door opening and closing device using a magnet and a push button, wherein the guide plate (6) is fixed, and the stroke of the magnet button is shorter than that of the push buttons (1) and (1 ').
