Description

[Detailed description of the invention] The present invention relates to a fixing device for a magnet device that is attached to the opening of a pencil case. It consists of two side U-shaped magnetic attraction plates, each having a horizontal bar protruding from the middle part of the wall, and a permanent magnet and elastic claws protruding from the upper and lower parts of the back plate capable of holding the horizontal bar from above and below. A fixing device for a magnet device in a pencil case, characterized in that the magnet device is inserted into the box and the horizontal bars are clamped from above and below by elastic claws of a suction plate to fix the magnet device to the box. It is related to.

Conventionally, as shown in Japanese Utility Model Publication No. 51-54016, it has been known to attach and fix a magnet device to the opening of the pencil case body, but the conventional method is to provide a protrusion on the inner wall of the box and attach the magnet The magnet device was fixed to the box by drilling a hole in the metal plate of the device and assembling them, but this protrusion gets in the way when inserting the device, and the protrusion easily slips out of the hole, causing the magnet to fail. There were drawbacks such as the device falling out of the box.

The fixing device according to the present invention is a completely new technology developed in view of the drawbacks of the prior art.

To specifically explain one embodiment of the device according to the present invention with reference to the drawings, in Figs. is installed so that it can be opened and closed freely. A box 4 with an open top and bottom is provided inside the opening of the writing case 1, and horizontal bars 5 and 6 are protruded from the middle portions of the front and rear inner walls of the box 4, respectively. Reference numeral 7 denotes a magnet device, which consists of a block-shaped permanent magnet 8 and side U-shaped magnetic attraction plates 9 and 10 that can hold the magnet 8 from both sides, and the back plates of the attraction plates 9 and 10 have A plurality of elastic claws 11 and 12 which can hold the horizontal bars 5 and 6 from above and below, respectively, are punched and bent from this back plate into a U-shape facing upwardly and downwardly, thereby resisting external pressure from one side. Therefore, it is configured to bend inward.

In the assembly configuration of the fixing device of the present application, as shown in FIGS.
When the magnet device 7 is assembled by being clamped and held together by the magnets 10 and then inserted into the box 4, the elastic claws 12 provided at the bottom of the suction plates 9, 10 are moved by the horizontal bars 5, 6. When the horizontal bars 5, 6 collide with the elastic claws 11 provided at the top, the elastic claws 12 that have passed through the horizontal bars 5, 6
The elastic claws 11, 12 stand up along the lower surface of the
The magnet device 7 can be mounted and fixed in the box 4 by sandwiching the horizontal bars 5 and 6 from above and below. Numerals 13 and 14 are suction fittings provided on the lids 2 and 3, respectively.

As mentioned above, the device according to the present invention forms a box with an open top and bottom at the opening of the writing case, and has horizontal bars protruding from the front and inner surfaces of the box, while the back plate of the suction plate of the magnet device has a box with an open top and bottom. A plurality of elastic claws are provided in parallel in corresponding positions above and below, which will protrude to the original state when the retracting and pressing is stopped by pressing from one side, so when inserting the magnet device into the box, the lower claw The magnet device can be smoothly inserted into the box because it falls down against the horizontal bar, and when the magnet device is fully inserted, the lower claw passes through the horizontal bar and stands up, aligning with the upper claw. In addition, it is possible to prevent the magnet device from falling out of the box by holding the horizontal bar from both the upper and lower sides, and the overall structure is simple to assemble and can be mass-produced at low cost.
