Description

[Detailed description of the invention] (Field of industrial application) The present invention is a magnetic door catcher for furniture that closes a door of furniture having a hinge type door, and in particular, a magnetic storage case is used as a mounting base. This invention relates to an improvement in a fine adjustment type magnetic door catch for furniture, which allows the installation position to be adjusted by sliding the door as appropriate.

(Prior Art) In a conventional fine-adjustment type furniture magnetic door catch, for example, as shown in FIG.
Magnet 2 with yoke 1 polymerized and adsorbed on the upper and lower surfaces
The magnetic storage case 3, which is loosely fitted, is fixed to the mounting base 6 with a male screw 4 and a female screw 5 (some cases are fixed with a single screw due to the structure). By loosening it, move the magnetic storage case 3 appropriately in the front and back direction,
By tightening the female screw 5 at a predetermined position, meshing teeth (not shown) formed on the sliding surfaces of the magnetic storage case 3 and the mounting base 6 are engaged with each other, and the magnetic storage case 3 is closed. I am trying to fix it.

(Problems 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 opening and closing the door is applied to the yoke 1 and the magnet. 2 to the female screw 5, the impact causes the screw to loosen, causing the magnet storage case 3 to move. If the magnetic storage case 3 moves, there is a possibility that the door will not be able to be closed even if the door is closed.

Further, in the conventional device, the male screw 4 is inserted from the bottom surface of the mounting base 6, and a space 7 is provided on the bottom surface of the mounting base 6 so that the male screw 4 can be lowered when the screw is loosened. As a result, the entire door catch becomes thick, which not only makes it unsightly and is unsuitable for furniture with outset doors, but also loosens the screws too much when making fine adjustments. It becomes impossible to screw together the female screw 5. Therefore, in this case, it is necessary to remove the mounting screws for the furniture, etc., remove the mounting base 6, and reassemble it, which is not only troublesome, but also causes the screw holes to be closed by removing the mounting screws. There is a risk that the mounting base 6 will become larger and that the mounting base 6 will not be able to be attached to that part.

Therefore, the present invention was 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. In addition, even if the fixing screw is loosened too much during fine adjustment, the magnetic storage case can be fixed in place by tightening the screw again without removing the mounting base from furniture, etc. Its purpose is to provide a networked architecture.

(Means for Solving the Problems) Therefore, in the present invention, the magnetic door catch is formed by forming the magnetic storage case from a resin material into a thin box shape having a rectangular opening on the front side. A protrusion that locks the magnet is formed approximately in the center of the upper and lower surfaces of the inside.
and a long screw hole is bored at the rear of the protrusion,
Engaging teeth are formed on both sides of the screw hole on the lower surface of the magnetic storage case, and further, an inclined surface is formed by cutting diagonally on both sides of the lower surface of the magnetic storage case, and meshing teeth are formed in the rear half of the inclined surface. At the same time, a locking tube with a female thread carved on the inside is installed in the center of the rear end of the mounting base, and on both sides of the locking tube, meshing teeth are provided that mesh with the meshing teeth formed on both sides of the screw hole of the magnetic storage case. furthermore, a flange having an inclined surface similar to the inclined surface is protrudingly provided on the upper surface of the mounting base at a substantially intermediate portion in the front-rear direction at a position opposite to the inclined surface formed on the magnetic storage case, The intended purpose is achieved by forming meshing teeth on the sloped surface of the flange that mesh with meshing teeth formed on the sloped surface of the magnet storage case.

(Function) With the above configuration, the magnet is locked to the protrusion formed on the magnet storage case via the yoke that is attracted to the magnet, and the rear end of the magnet is connected to the locking cylinder provided upright on the mounting base. It is designed so that it does not come into contact with the Therefore, even if an impact is applied to the magnet or yoke due to opening and closing of the door, the impact will not be transmitted to the locking tube. Therefore, the impact is not transmitted to the fixing screw screwed into the locking cylinder, so the fixing screw does not loosen due to the impact.

Further, the impact is transmitted to the magnetic storage case through the protrusion, but the magnetic storage case has meshing teeth formed at four locations on both sides of the screw hole of the magnetic storage case and on both the left and right sides, and the mounting base. Since the meshing teeth are meshed with each other, they will not slide due to the impact. Furthermore, the sloped surfaces formed on both sides of the bottom surface of the magnetic storage case are in close contact with the flanges formed on the top surface of the mounting base, so that the impact of unbalanced loads applied to the magnet and yoke (normally doors are not hinged). Because the door rotates around the center, the impact caused by opening and closing the door is not applied evenly to the front of the magnet and yoke, but is applied closer to the hinge.Therefore, the magnet and yoke have locking parts. ), even if a force in the direction of rotation is applied to the magnetic storage case via the magnet or yoke, the rotation is prevented by the flange. This can also prevent the fixing screw from loosening.

(Example) The present invention will be described below with reference to an illustrative example.
