Description

  The present invention relates to a case for storing a portable electric product, and more particularly, to a configuration that can prevent the magnet provided in the case and the influence on the electric circuit from the outside.

Portable small electronic products such as portable telephones and CD players are widespread. They are often carried in a leather case or the like.
A belt, hook, magnet, or the like is used as a mechanism for opening and closing the case. Of these, the case using the magnetizing action of the magnet for opening and closing is convenient for easy opening and closing smoothly.

However, if a magnet is provided in the case, the magnetic force may adversely affect the electrical product.
Electrical products may be provided with sensors that detect magnetism, which may cause malfunctions. In addition, an induced current generated with the movement of the magnet may affect the circuit. For example, a malfunction that a display of a mobile phone emits light has been reported.

For example, Patent Document 1 discloses a storage case for a portable telephone using a magnet. However, such a prior art has not taken into consideration a device for preventing the adverse effect of the magnet.

  Accordingly, an object of the present invention is to provide a storage case for a portable electrical product that can prevent the influence of magnetic force on a magnet provided in the case and an external electric circuit.

  In order to achieve the above object, a portable electrical product storage case of the present invention has the following configuration. That is, in a case for storing a portable electric product, a container having a substantially box shape having an opening and containing the electric product, and a substantially tongue-like piece projecting from the container and having a container opening. A lid body that opens and closes, and the engaging portion of the housing body and the engaging portion of the lid body, which are portions that engage with each other when the lid is closed to form a closed state, can be substantially in contact with each other. A magnet is disposed on at least one of the body engaging portion and the lid engaging portion, and a magnetizable metal plate is disposed on the side where the magnet is not disposed. It controls opening and closing, and further, a substantially plate-like magnetic absorbing material is disposed on the inner side of the magnet in the container engaging portion.

  Here, a magnetically adherent metal plate is disposed in the lid engaging portion, a magnet is disposed in the housing engaging portion, and a magnetic absorber is disposed on the inner side thereof. May not be provided with a magnet. Then, the induced current accompanying the approach of the magnet of a cover body engaging part and a movement is prevented.

  In addition, a non-magnetic material such as plastic is disposed further inside the magnetic absorber disposed in the container engaging portion to further suppress the influence of the magnet disposed in the container engaging portion. Also good.

  An iron plate can be suitably used as the magnetic absorber disposed in the container engaging portion.

  According to the present invention, the mechanism for opening and closing the case uses the magnetizing action by the magnet, so it is convenient to open and close the case smoothly. Moreover, although the magnet is used, the influence of the magnetism on the electrical product can be prevented.

Embodiments of the present invention will be described below with reference to the drawings.
Here, a portable telephone is illustrated as a portable electric product stored in the case, but any portable small electric product such as a CD player or a PDA is applicable as the electric product stored in the case.

1 and 2 are perspective views showing a use state of the case for a portable telephone according to the present invention, in which FIG. 1 shows an open state and FIG. 2 shows a closed state. FIG. 3 is an explanatory plan view of the case in the opened state.
The portable electrical product storage case according to the present invention includes at least a storage body (10) and a lid (20).
The container (10) is substantially box-shaped, and the portable telephone (30) is taken in and out from the opening (11).
The lid (20) has a substantially tongue-like shape protruding from the vicinity of the opening (11) of the container (10) and has a configuration for opening and closing the opening (11).

The surfaces of the engaging portion (12) of the container (10) and the engaging portion (21) of the lid (20), which are portions that engage with each other when the lid is closed, are substantially flat. It has become.
The lid engaging portion (21) has a magnetized metal plate (22) embedded therein, and the housing engaging portion (12) includes a magnet (13) and a magnetic absorption member. The material (14) is embedded in order.
Therefore, the container (10) and the lid (20) are controlled to contact and separate by the magnetic adhesion action between the magnet (13) and the magnetizable metal plate (22), and the container engaging portion (12). Since the surfaces of the lid engaging portion (21) are both substantially flat, both slide smoothly along the surface, so that the contact / separation operation is easy.

  The magnetizable metal plate (22), the magnet (13), and the magnetic absorber (14) may be exposed on the surface without being embedded in the case material.

As the magnetic absorber (14), a magnetically adherent metal plate such as an iron plate can be used.
The area of the magnetic absorber (14) in the plane parallel to the container engaging portion (12) is designed to be larger than that of the magnet (13), so that magnetism from the magnet (13) is caused by the magnetic absorber (14). It is difficult to be transmitted to the mobile phone (30) by being dispersed.

FIG. 4 is a plan view of the case in an open state showing another embodiment.
In the present embodiment, the magnet (23) is also disposed in the lid engaging portion (21). By arranging the magnets (13) and (23) at the joints (12) and (21), the magnetic force is enhanced.
However, when the magnet is not provided in the lid engaging portion (21) as in the above embodiment, the approach of the magnet that occurs when the lid (20) is moved and the induced current that accompanies the movement of the magnet are prevented. There are advantages to being.

  In the present embodiment, a non-magnetic material (15) such as a plastic is disposed further inside the magnetic absorber (14) disposed in the container engaging portion (12). Since the magnetism from the magnet (13) is blocked by the nonmagnetic material (15), the influence on the mobile phone (30) is further suppressed.

  According to the present invention, the utility value is high because it is easy to open and close the case and can prevent the influence of magnetism while having a simple configuration.
