Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a temporary lock type magnetic catch, and more particularly to a magnetic catch having a function of automatically adjusting the protruding position of the adsorbent.

<Prior art> Generally, when a magnetic catch is attached to furniture, if there is a gap between the attracting body of the magnetic catch and the target body attached to the rotating door side, the suction effect of the magnetic catch will be significantly reduced. It must be installed correctly to avoid gaps.

Therefore, in the past, there have been many types of magnetic catch in which the adsorbent body is formed so as to be movable in the front and rear directions with respect to the casing, and can be fixed at a predetermined position with fixing screws.

<Problems to be Solved by the Invention> However, the above-mentioned conventional means is very troublesome because it requires manual adjustment of the contact with the door each time it is installed.

Therefore, the main purpose of this invention is to solve the above-mentioned problems by automatically adjusting the protruding position of the adsorbent for a magnetic catch attached to a furniture frame by simply closing the door. That is.

<Means for solving the problem> In order to achieve the above purpose, the present invention has a magnetic plate 1
A and a yoke plate 1b are held together by a synthetic resin frame 1c, and this adsorbent 1 is attached to a front opening 2.
a casing 2 that can be retracted and retracted from a, and a spring 3 that constantly presses the adsorbent 1 in the projecting direction.
The adsorbent 1 can slide in the pushing direction by engaging the directional ratchet teeth 4 formed on its upper surface with the teeth 5 elastically supported on the casing 1 side, but cannot slide in the projecting direction. Furthermore, the tooth body 5 is rotatably supported by a vertical pivot shaft, and the pivot shaft 6 is inserted into the top plate from a hole 7 formed in the top plate 2b of the casing 2. It is exposed upward, and an engagement groove or a rotation knob for a screwdriver or the like is formed at the exposed end, and the rotation shaft 6 is rotated to move the teeth 5 from the engaged position by 90 degrees.
The tooth body 5 is configured to be able to be disengaged from the ratchet teeth 4 by rotating the tooth body 5 once.

<Function> As shown in FIG. 4, the magnetic catch configured as described above can be installed on the furniture frame A with the adsorbent 1 protruding greatly, and then the magnetic catch can be opened by closing the door B. , the suction body 1 is pushed by the door and retreats as shown in FIG. 5, and can be automatically held in close contact with the suction target 8 of the door at a predetermined door closing position. Also, by rotating the rotating shaft 6 with a screwdriver or the like to rotate the tooth body 5 by 90 degrees from the engaged position, the engagement with the ratchet teeth 4 is released, thereby returning the adsorbent body 1 to its original protruding position. can be done.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes an adsorbent of the magnetic catch according to the present invention, which is formed by a magnet plate 1a and yoke plates 1b, 1b integrally held together by a synthetic resin frame 1c. The adsorbent 1 is held by a casing 2 so as to be retractable from its front opening 2a, and is constantly pressed in the projecting direction by a spring 3. Further, the adsorbent 1 has directional ratchet teeth 4 formed on its upper surface extending in the front-rear direction. And this ratchet tooth 4
A tooth body 5 supported on the casing 1 side is elastically engaged with the casing 1 side via a spring 12, so that the adsorbent body 1 can slide in the pushing direction but is prevented from moving in the projecting direction. There is. The tooth body 5 has a disk shape and is supported rotatably by a vertical pivot shaft 6 and movably upwardly against the spring 12. The rotation shaft 6 is exposed above the top plate through a hole 7 formed in the top plate 2b of the casing 2, and an engagement groove 13 for a screwdriver or the like is formed at the exposed end. By rotating the tooth body 5 by 90 degrees from the meshing position, the meshing teeth of the tooth body 5 are changed to a direction perpendicular to the ratchet tooth 4, and the tooth body 5 is rotated 90 degrees from the meshing position.
It is configured such that the engagement with the ratchet teeth 4 can be released by riding on the ratchet teeth 4. Incidentally, in place of the engagement groove 13, a rotary knob portion that can be operated by hand may be formed.

Reference numeral 14 designates the bottom plate of the casing 2, which is bonded to the casing with an adhesive.

As shown in FIG. 4, the magnetic catch configured as described above can be used by attaching the adsorbent 1 to the furniture frame A with the adsorbent 1 protruding greatly, and then closing the door B. 1 is pushed by the door and retreats as shown in FIG. 5, and can be automatically held in close contact with the object to be attracted 8 of the door at a predetermined door closing position. Furthermore, when the rotating shaft 6 is rotated with a screwdriver or the like to rotate the tooth body 5 by 90 degrees from the meshing position, the meshing teeth of the tooth body 5 are converted to a direction perpendicular to the ratchet teeth 4 and the tooth body 5 is rotated 90 degrees from the meshing position. It rides on the ratchet teeth 4, thereby disengaging from the ratchet teeth 4 and allowing the suction body 1 to return to its original protruding position. In this case, as shown in FIG. 3, if the design is made in advance so that when the adsorbent 1 is fully pushed into the casing 2, the meshing portion of the ratchet teeth 4 with the tooth body 5 is eliminated, the rotational movement The shaft 6 can be rotated smoothly.

<Effects of the invention> Since the present invention is configured as described above, if the adsorbent 1 is attached to the furniture with the adsorbent 1 protruding largely from the casing 2, the adsorbent 1 can be attached to the door simply by closing the door B. The door can be pushed back and automatically fixed in a predetermined door closing position in close contact with the adsorbed object 8 of the door, which is convenient as it can omit manual adjustment each time it is installed. , In addition, if you accidentally replace adsorbent 1 with casing 1
Even when the suction body 1 is pushed inward, the suction body 1 can be easily returned to its original protruding position by rotating the rotation shaft 6 and releasing the engagement of the teeth 5 with the ratchet teeth 4. It has the advantage of being able to be used repeatedly.
