Description

[Detailed explanation of the idea]

[0001]

[Industrial Application Field] This invention is for keeping the door closed by attracting the free end of the door hinged to the main body, such as a front panel hinged to the front of a video deck, with a magnet. Regarding magnetic holders.

[0002]

[Prior Art] As shown in FIGS. 3 and 4, a conventional magnetic holder has a convex-shaped protrusion 1'.
A magnet piece 2 having the same shape as the main body of the yoke plate is sandwiched between two magnetic yoke plates 1, 1 having an adsorption body 3, and the protrusions 1', 1 of both yoke plates on the front surface. The adsorbent body 3 is later accommodated in a cylindrical housing 4 having an opening 4' through which the portion 1' can protrude outward, and then an elastic sponge piece 5 is inserted, and while compressing the sponge piece, the absorber 3 is inserted into the housing 4. Attach the bottom plate 6 to the end with adhesive or the like to close it up, and use the elasticity of the sponge pieces to press the adsorbent 3 so that the protruding parts 1', 1' of each yoke piece are pushed out through the opening 4' on the front surface of the housing.
When the protrusions 1' and 1' are pushed by the free end of the door when the door is closed, both yoke plates compress and retract the sponge pieces, buffering the force of closing the door. ing.

[Problems to be solved by the invention] Magnetic holders are generally extremely small parts, and it is troublesome to even assemble and insert the adsorbent 3 into a small housing. In addition, it is necessary to glue and fix the bottom plate to the rear end of the housing at the end, making assembly extremely time-consuming. Furthermore, in order to attach this magnetic holder to the main body, it is necessary to pass screws through the left and right flanges that protrude from the front end of the cylindrical housing, and screw these screws into the main body to secure it. It is also very time consuming.

[0004]

[Means for Solving the Problems] The present invention was developed with the aim of eliminating both the number of steps required for assembly and the number of steps required for attachment to the main body. An adsorbent with a magnet piece sandwiched between plates is housed in a housing made of plastic, and the adsorbent is compressed by a spring piece in the housing to cause the protruding parts of both yoke plates to protrude outward from the front surface of the housing. In the magnetic holder, the housing includes a cylindrical accommodating part into which the adsorbent can be inserted from the open rear end, and a hinge connected to one side of the rear end of the cylindrical accommodating part, a lid wall that closes an open rear end; A collar projecting outward is provided, and mounting wings projecting diagonally forward on both sides of the rear end portion are provided, and the lid wall has an integrated body whose one end is joined to the lid wall on the surface facing the inside of the cylindrical storage portion. It is characterized by the provision of an arcuate spring piece.

[0005]

In the embodiment shown, a housing 10 molded from plastic comprises a cylindrical storage section 11 into which an adsorbent 3 can be inserted from its open rear end, and a cover wall 13 which is integrally connected to one side of the rear end of the cylindrical storage section 11 by a thin hinge 12 and which closes the open rear end of the storage section.

[0006] The cylindrical housing part 11 has a front end wall 1.
4, and the left and right guards 15, 15 that extend outward from both sides.
The front end wall 1 has left and right mounting wings 16, 16 projecting diagonally forward and outward from both sides at the rear end.
4 is provided with an opening 17 through which the protruding portions 1' of both yoke plates of the adsorbent 3 can protrude outward.
The lid wall 13 also has a front end wall 14 when the hinge 12 is bent to close the open rear end of the cylindrical housing portion 11.
an arcuate spring piece 18 with one end joined to the inner surface facing the
is provided.

[0007] In order for the lid wall 13 to maintain the opened and closed rear end of the cylindrical accommodating portion 11 in a closed state, a claw 19 is engaged with the free end of the lid wall 13, and the aforementioned claw is engaged with the accommodating portion 11. A hole 20 is provided. Note that the claw 19 may be provided in the housing portion 11 and the hole 20 may be provided in the cover wall 13.

[0008] To assemble, insert the adsorbent 3 from the rear into the cylindrical housing part 11 in the molded state shown by the broken line in FIG. Take it out through the opening 17 in the wall 14. Then, the hinge 12 is bent to push the cover wall 13 into the rear end of the cylindrical housing part 11, the claw 19 is engaged with the hole 20 to fasten the lid wall 13, and the open rear end of the cylindrical housing part 11 is is closed with a cover wall 13. With this, the cover wall 1
An arcuate spring piece 18 provided on the inner surface of the absorber 3 elastically presses the absorber 3 from behind.

[0009] To attach it to the main body 21, open a mounting opening 22 in the main body through which the cylindrical accommodating part 11 can pass, and push the cylindrical accommodating part into the mounting opening 22 from the rear end as shown by the arrow in FIG. . This allows mounting wing 1
6 and 16 are bent inward and the cylindrical housing part enters the mounting opening, and when the flanges 15 and 15 come into contact with the edge of the mounting opening, the mounting wings 16 and 16 pass through the mounting hole and end. The holder is elastically restored and hooked onto the back edge of the mounting opening to fix the holder to the main body 21.

[0010] When the door, which is attached to the main body by a hinge or the like, is closed, the protrusion 1' of the suction body 3 is pushed into the free end of the door at the end of the closing process, and the yoke plates 1, 1 deform the arc-shaped spring piece 18 and pull it into the cylindrical accommodating section 11, cushioning the force closing the door, and when the force closing the door is released, the arc-shaped spring piece 18 returns to its original state and pushes the yoke plate back to its original state, and the magnetic force of the magnetic piece 2 keeps the door in the specified closed position.

[0011]

[Effect of the invention] As is clear from the above, according to the present invention, the adsorbent is inserted into the cylindrical accommodating portion 11 from the rear end with the protrusions 1', 1' of the adsorbent 3 at the tips, The hinge 12 is bent to close the rear end of the cylindrical housing portion with the lid wall 13. As a result, the arcuate spring piece 18 on the inner surface of the lid wall pushes the suction body 3 from behind, causing the suction body 3 to
The front end of the protrusion 1' is connected to the opening 1 in the front end wall 14.
It can be taken out and assembled from 7 and is very easy to assemble. Also, to attach it to the main body, it is only necessary to open a mounting opening 22 in the main body through which the cylindrical accommodating part 11 passes, and push the cylindrical accommodating part into the mounting opening from behind while bending the mounting wings 16 inward. Therefore, it can be attached to the main body with one touch without the need to screw in screws.
