Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a magnetic door catch for furniture that closes a door of furniture having a hinged door.

(Prior Art) In a conventional fine-adjustment type furniture magnetic door catch, for example, as shown in FIG. 10, a magnetic storage case 3 is provided with a loosely fitted magnet 2 having a yoke 1 superimposed and adsorbed on its upper and lower surfaces. The magnetic storage case is fixed to the mounting base 6 with a male screw 4 and a female screw 5 (some models are fixed with a single screw due to the structure). 3 in the front-back direction as appropriate, and by tightening the female screw 5 at a predetermined position, the meshing teeth (not shown) formed on the sliding surfaces of the magnet storage case 3 and the mounting base 6 are removed. The magnet storage case 3 is fixed by meshing with each other.

(Problem to be solved by the present invention) However, in the conventional magnetic door catch described above, since the female screw 5 directly penetrates the yoke 1 and the magnet 2, the impact caused by the opening and closing of the door is applied to the yoke 1 and the magnet. 2 to the female screw 5, the impact causes the female screw 5 to loosen, causing a problem in that the magnet storage case 3 moves. If the magnetic storage case 3 moves, there is a risk that the door will not be able to be closed even if the door is closed.

The present invention has been developed in view of the above-mentioned conventional problems, and is capable of reliably fixing the magnetic storage case, and also prevents the fixing screws from loosening due to the impact of opening and closing the door. The purpose of this invention is to provide a magnetic door catch.

(Means for Solving the Problem) Therefore, in the present invention, the magnetic door catch is integrally formed with a spring piece extending horizontally from the center of the lower surface in the left and right direction on the lower surface of the magnetic storage case. Both ends of the spring piece are engaged with the side edges of the lower end opening of the magnetic storage case fitting part of the mounting base, and meshing teeth are formed in the front and back direction of the engagement surface, and the magnet of the magnetic storage case is The storage part has a screw hole that communicates with the screw hole drilled in the magnet storage case, and a locking means is formed on the outer periphery for fitting and locking the yoke superimposed and adsorbed on the upper and lower surfaces of the magnet. The structure is such that meshing teeth that mesh with the meshing teeth are formed on the side edge of the lower end opening of the magnetic storage case fitting part of the mounting base that faces the teeth, or there are meshing teeth formed in the center of the lower ends of both sides of the magnetic storage case. a spring piece extending horizontally in the direction is integrally formed, and both ends of the spring piece are engaged with the lower surface of a mounting piece extending integrally from both sides of the magnetic storage case fitting part of the mounting base, Engaging teeth are formed in the front-back direction on the engagement surface, and a screw hole is provided in the magnet storage part of the magnet storage case that communicates with a screw hole drilled in the magnet storage case, and a screw hole is formed on the outer periphery of the magnet storage case. A locking means for fitting and locking the yoke superposed and adsorbed is formed on the lower surface, and meshing teeth that mesh with the meshing teeth are formed on the lower surface of the mounting piece of the mounting base that faces the meshing teeth. It was designed to achieve the intended purpose.

(Function) With the above configuration, after the magnetic storage case is assembled into the magnetic storage case fitting part of the mounting base, by tightening the fixing screw, the magnetic storage case and the mounting base are formed on the sliding surfaces. The meshing teeth mesh with each other, and the meshing teeth formed on both ends of the spring piece formed on the magnetic storage case mesh with the side edge of the lower end opening of the magnetic storage case fitting part of the mounting base or on the lower surface of the mounting piece. The teeth engage and the magnetic storage case is fixed.

When fixing the magnetic storage case,
Since the spring piece acts like a spring washer due to its elasticity, the magnet storage case is fixed more reliably.
Further, even if an impact is applied to the magnet or yoke due to opening and closing of the door, the impact is alleviated by the spring piece and blocked by the locking means,
Since the impact is not transmitted to the fixing screw, the screw will not loosen due to the impact. Furthermore, even if the fixing screws naturally loosen slightly due to long-term use of the magnetic door catch, the magnetic storage case will be fixed to the mounting base by the action of the spring washer of the spring piece. Since the magnetic storage case can be held in a closed state, the magnetic storage case will not slide or move.
