Description

[Detailed description of the invention] [Field of industrial application] This invention is a retractable magnet that is provided with a magnet around the outlet of the box that stores the gem clip, and which always attracts and holds the gem clip at the outlet. Regarding BOTS.

[Conventional technology]

Conventionally, this type of magnetic box has been formed into a substantially rectangular parallelepiped as shown in FIG. They were connected by fitting or gluing.
The upper case 22 has an outlet 23, and the side wall 2
A magnet 25 is fixed to the inside of 4.
As a result, when one of the gem clips in the storage chamber 26 is attracted to the magnet 25 through the side wall 24, the other gem clips are successively attracted, and when a gem clip is taken out along the drawer surface 27, the magnet 25 is continuously attracted. The structure was such that a gem clip was held in the part.

[The problem that the idea attempts to solve]

In the above-mentioned conventional magnetic boxes, the height of the magnetic box is set in advance at the time of manufacture, and various types of magnetic boxes are used depending on the amount of gem clips to be stored and the height of the desk drawer in which they are stored. Therefore, it is necessary to manufacture and prepare many types of magnetic boxes, which increases costs, and it is inconvenient for users to change the product depending on the application. When storing in a desk drawer, magnetic boxes of various heights were sometimes required depending on the height of the desk drawer.

[Means to solve the problem]

In order to solve the above-mentioned problems of the conventional magnetic box, the present invention provides a lower case including a cylindrical side wall with a thread formed thereon and a fixed wall provided on the outer periphery of the lower end of the side wall, and a screw on the side wall of the lower case. an upper case having a cylindrical side wall with a mating screw, an extraction port around which a magnet is fixed, and a ring-shaped protrusion; The magnetic box is composed of a ring-shaped protrusion and an elastic bellows having a ring-shaped groove that fits therein, and the lower end of the bellows extends so as to surround the outer peripheral surface of the bottom of the lower case. You can. This allows the height and capacity of one magnetic box to be changed arbitrarily.

[Effect]

Since the present invention is constructed as described above, when the upper case is rotated, the height of the magnetic box changes due to the screw engagement between the side wall of the upper case and the side wall of the lower case, and the capacity also changes.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 and 2.

The magnetic box 1 consists of a lower case 2, an upper case 3, and a bellows 4 provided on the outer periphery of the lower case 2 and the upper case 3. The lower case 2 has a cylindrical side wall 5
It has the shape of a container with an open top and a fixed wall 6 around the lower end and a bottom 7. A female thread 8 is formed on the inner peripheral surface of the side wall 5. The upper case 3 has a take-out opening 10 at its constriction, and on its outer periphery there are magnets 1 separated into a plurality of pieces, each forming a part of a ring.
1 is fixed. A cylindrical side wall 15 having an inclined wall 12 and a male thread 14 screwed into the female thread 8 of the side wall 5 of the lower case 2 is provided at the upper part of the extraction opening 10 . A ring-shaped projection 13 extending horizontally is provided on the outer periphery of the upper end of the inclined wall 12. A ring-shaped groove 16 that loosely fits into the ring-shaped protrusion 13 of the upper case 3 is provided from the outside to the lower part of the extraction opening 10 of the upper case 3.
A bellows 7 made of an elastic body is fixed to the fixed wall 6 of the lower case 2 with an adhesive or the like. Further, as shown in FIG. 3, the lower end 17 of the bellows 4 may extend from the outer periphery of the fixed wall 6 of the lower case 2 to surround the outer peripheral surface of the bottom 7.

When assembling the magnetic box with the above configuration, the lower end 17 of the bellows 4 is fixed to the outer periphery of the fixed wall 6 of the lower case 2, and the male thread 14 of the upper case 3 is screwed into the female thread 8 of the lower case 2. , the ring-shaped protrusion 13 of the upper case 3 is connected to the ring-shaped groove 16 of the bellows 4.
On the other hand, the bellows 4 is assembled by fitting into the bellows 4 due to its elasticity.

In use, when the upper case 3 is rotated in the direction of the arrow in Fig. 2, the ring-shaped protrusion 13 of the upper case 3 and the ring-shaped groove 16 of the bellows 4 are loosely fitted, so the bellows 4 is screwed. The upper case 3 rotates without being rotated, and the height of the upper case 3 changes due to the screws in the side wall 15 of the upper case and the side wall 5 of the lower case 2. Furthermore, the bellows 4 expands and contracts in accordance with changes in the height of the case 3. Therefore, the user of the magnetic box can change the height and capacity to any desired size by twisting the upper case 3 as required. After setting in this way, when one of the gem clips placed in the case is taken out from the take-out opening, the other clips are connected in a chain by the action of the magnet, and the other clips are attracted to the peripheral wall of the take-out opening. Retained.

In the above embodiment, a female thread was formed on the side wall of the lower case, and a male thread was formed on the side wall of the upper case. The lower case may have a male thread and the upper case may have a matching female thread.

[Effect of idea]

Since the present invention is constructed as described above, the magnetic box can be changed to any desired height and capacity by rotating the upper case. Furthermore, when storing the magnetic box in a desk drawer, the height can be easily changed to any desired height depending on the situation of the storage area. Additionally, the bellows maintain approximately the same appearance despite changes in height and capacity.

In addition, since the bellows are made of elastic material, the upper case
Fitting into the lower case and assembling work are easy, and even if the magnetic box swings in a desk drawer and comes into contact with other stationery, it will not be damaged due to mutual buffering action. Furthermore, if the lower end of the bellows extends so as to surround the bottom outer circumferential surface of the lower case, the lower case will be completely fitted to the fixed wall, and the magnetic box will not be placed on the desk. When doing so, it is possible to prevent the desk from being scratched.
