Description

  The present invention relates to a protective case for storing a portable information device.

There are various protective cases for protecting portable information devices such as mobile phones or portable information terminals, which are precision electronic devices, from external impacts, etc., depending on the shape and application of the device. Proposed.

  Even if the conventional general mobile phone has a difference in the shape of an integrated type or a two-fold type, its interface is usually composed of a liquid crystal display screen and a group of key buttons. It is common to have a shape in which the main body is taken out when used by storing and carrying, or only the liquid crystal display screen or key button part is exposed at all times or during use.

  On the other hand, in recent years, as mobile information devices have become more sophisticated and multifunctional, mobile phone functions that do not have a key button group and can be used by touching a large touch panel LCD screen with a finger Portable information devices equipped with are rapidly spreading. Moreover, such touch panel type portable information devices are not only of the same size as conventional mobile phones, but, for example, a case having a casing of about A4 size and a liquid crystal display screen of about 10 inches diagonally has been developed. Yes.

  In such touch panel type portable information devices, since the liquid crystal display screen occupies a wide area on the front of the device body, the user generally holds the outer part of the device body with one hand and operates the touch panel with the other hand. is there. Therefore, in addition to the shape of the protective case, the entire device body is housed in a protective member and removed when in use, the front surface of the device body is open, and only the outer and back surfaces are covered with a protective member. Molds are the mainstream.

Many of the front open type protective cases are made by integrally molding an elastic material such as silicone rubber or hard resin material such as plastic. As for the latter, what is closely attached to the main body is generally one in which the main body device can be exactly inserted into the protective case.

These protective cases are made of materials that have a transparent or colored material, or are processed mainly by coloring or drawing patterns on the back surface to provide protective cases of various colors and designs. The number of users who prepare a plurality of protective cases for one portable information device and use them for replacement is increasing.

This reflects the tendency of users to seek expression of personality in information equipment that they always carry. While this protective case naturally has the function of protecting the original portable information device, it has a sense of quality or texture that exceeds the level of simple accessories, and a variety of designs tailored to the TPO and the user's mood. It is clear that the need for enjoying the mobile phone is increasing further from the fact that many manufacturers other than the manufacturer of the portable information device have entered the manufacture and sale of the protective case alone.

  Even in the case of the front open type protective case, the high protective function of the original portable information device and the durability of the protective case itself, while providing a higher level of quality and high quality, and having a high level of design. Application of a material member is conceivable. Examples of such high-quality members include metal materials that have a profound feeling and are suitable for high-quality painting, three-dimensional processing, and surface processing such as etching, but also wood and lacquering processing. In addition to decorative members that have been subjected to raving, inlaying, etc., various types of leather can be considered.

  By the way, as described above, a touch panel type portable information device needs to be a front open type in consideration of convenience in use. On the other hand, the outer part not only needs to be slippery when the device main body is held with one hand in the use environment, but also is a part that is easily subject to shock when dropping etc. High material is desirable. The rear part has a large area and is the most visible part except for the front interface, so it is suitable for the above-mentioned high-quality materials, but it is not used outside when not in use, such as when a portable information device is placed on a table etc. Therefore, it is desirable to protect the high quality member itself from friction and the like. Furthermore, in view of the needs of the above-mentioned users, it is desirable to have a structure in which a plurality of high-quality members and outer parts having different textures and designs are held as replacement parts and can be used by freely replacing them.

  Here, when a hard material such as a metal is used as a high-quality member used for the back plate, the impact from the back surface is directly conducted to the portable information device, and the hard material is attached when the protective case is attached to or detached from the device. Since the wear on the back of the equipment due to the friction with the device is considered, it is necessary to consider the countermeasures.

  In addition, since a portable information device generally has a camera lens for taking a photograph or a moving image on the back surface, it is necessary to provide an opening for the camera lens on the back surface of the protective case. As described above, the opening can be an accent on the design of the back surface of the protective case, which is usually flat. Therefore, it is desirable to design the opening in consideration of this point.

  In order to solve the above problems, a portable information device protective case according to the present invention has the following configuration.

The invention described in claim 1 is a portable information device protective case in which a back plate is detachably fitted to an outer portion, and the outer portion is formed to be in close contact with the outer periphery of the side surface of the device main body. The back plate is made of a plate-like member that is in close contact with the back surface of the device body and covers the whole.

The invention described in claim 2 is the portable information device protective case according to claim 1, wherein the back plate is covered with a covering material on the surface that is in close contact with the back of the device body. And

The invention described in claim 3 is the portable information device protective case according to claim 1 or 2, wherein the back plate is formed on the outer edge portion that fits the outer portion. Thickness is large and the cross section is formed in the substantially convex shape which protrudes from an apparatus main body back side.

The device described in claim 4 is the portable information device protection case according to any one of claims 1 to 3, wherein the back plate has a groove on the outer edge surface that fits with the outer portion, The outer portion has a linear convex portion on an inner surface portion to be fitted with the back plate, and the groove portion and the convex portion are fitted and fixed to each other.

And

First, according to the portable information device protective case according to claim 1, it is composed of two members, an outer portion and a back plate, and these are detachably fitted to form a protective case. Various combinations can be realized by preparing a plurality of members of patterns and patterns, and so-called "customization" can be made according to the user's preference and TPO. In addition, the outer portion is made of an elastic body formed in a substantially band shape so as to be in close contact with the outer periphery of the side surface of the device body. Therefore, the outer portion can be easily attached to and detached from the device by stretching the outer portion. Since the device itself is tightened by its own elasticity, the device will not accidentally fall out of the protective case. In addition, the back plate is made of a plate-like member that is in close contact with the back of the device and covers the entire surface. Therefore, the back of the device is protected, and the back plate itself exhibits a high-class feeling and high quality and is highly designed. An excellent decorative effect can be obtained by using a high-quality member having the above.

  The protective case may be attached to the main body of the device by attaching the main body of the device to the protective case with the back plate fitted to the outer side, or by previously overlapping the back plate of the main body of the device. You may hold | maintain and may fit an outer part.

  According to the portable information device protection case according to claim 2, the surface of the back plate that is in close contact with the back of the device main body when attached is covered with the covering material, so that the high-quality member used for the back portion Even when a hard material such as metal is used, the impact from the back surface is directly transmitted to the portable information device, or the wear on the back surface of the device due to friction with the hard material when the protective case is attached to or detached from the device. Can be prevented.

As the material of the covering material, a soft material formed in a shape overlapping with the back plate, for example, a sheet of plastic or silicon rubber, or a thermoplastic polyurethane (TPU) softer than plastic and harder than silicon rubber is suitable. However, the material is not limited to these as long as it is easy to mold and exhibits the above-described effects. The covering material may be an independent member, but from the viewpoint of easy mounting of the protective case to the device, it is desirable to bond it integrally to the back plate in advance.

According to the portable information device protective case according to claim 3, the back plate has a thickness other than that of the outer edge portion fitted to the outer side portion, and the cross section protrudes from the back side of the device body.

As described above, according to the configuration of the portable information device protective case according to the present invention, it naturally has the function of protecting the original portable information device, but it has a high-class feeling or high level that exceeds the level of simple accessories. It is possible to provide an attractive and highly competitive portable information device protection case that meets the needs of consumers to enjoy a variety of designs tailored to the texture, TPO and user's mood. In addition, the portable information device protective case according to the present invention is not limited to a portable information device of a conventional mobile phone size, but a larger one having a touch panel type liquid crystal display screen, for example, a case whose size is about A4 size. It can also be applied to things.

  Hereinafter, a preferred embodiment of a portable information device protection case according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an overall perspective view illustrating the appearance of the latest model of a typical touch panel type portable information device in the Japanese market. The shape of the device main body 1 is a substantially rectangular parallelepiped with rounded corners, and a touch panel type liquid crystal display screen 2 occupies most of the front surface of the device. A terminal socket 3 to which a cable connector for charging or data transfer is attached is disposed at the center of the lower surface of the apparatus body. FIG. 2 is an overall perspective view illustrating the appearance of the device viewed from the back. A camera lens 4 and a flash 5 for taking pictures / moving pictures are disposed on the back of the apparatus.

FIG. 3 is an overall perspective view showing a state where the touch panel type portable information device shown in FIGS. 1 and 2 is attached to the portable information device protection case of the embodiment according to the present invention. The outer portion 10 surrounds the entire outer peripheral side surface portion of the device main body 1 and also covers the entire front surface edge portion of the device with a uniform width.

FIG. 4 is an overall perspective view illustrating the appearance of the protective case with the device main body 1 of FIG. The outer side portion 10 covers the outer peripheral edge portion of the back plate 20 over the entire circumference with a uniform width. The back plate 20 may be a flat plate-like body that overlaps with the back of the device body 1. However, in this embodiment, the back plate 20 has a larger thickness at the other portions than the outer edge, and has a cross section. Is formed in a substantially convex shape that protrudes from the back side of the device main body, and as a whole, the surface immediately rises from the edge. As a result, a three-dimensional effect is generated as compared with the case where the back plate 20 is a simple plate shape, and a high-class feeling and profound feeling are added to the appearance.

FIG. 5 is an overall perspective view showing the structure of the portable information device protection case according to the embodiment of the present invention. The left figure shows a state in which the back plate 20 is fitted to the outer part 10, and the right figure shows a state in which the back plate 20 is separated from the outer part 10. The back plate 20 has a two-layer structure in which the covering material 22 is bonded to the entire surface of one surface of the hard member 21 (the surface that is in close contact with the back surface of the device main body 10).

FIG. 6 is a cross-sectional perspective view showing a cross section when the protective case with the device main body 1 of FIG. 4 attached is cut along the line XX ′. The cross-section of the outer portion 10 has a substantially U-shape facing each other, and each has a structure in which the side end portion of the device main body 1 is sandwiched between U-shapes. As described above, since the material of the outer portion 10 is an elastic body, the outer portion 10 at the time of wearing is tensioned in the direction of the arrow in the drawing by its own elasticity, so that the outer portion 10 does not fall off from the device body 1. ing.

FIG. 7 is an enlarged cross-sectional view in which a cross-section of a portion surrounded by a circle Y in FIG. 4 is further enlarged. A groove 23 is provided on the outer edge surface of the back plate 20 in contact with the outer portion 10. On the other hand, a linear convex portion at a position corresponding to the groove 23 is formed on the U-shaped inner surface of the outer portion 10 in the back direction. 11 and the groove portion 23 and the convex portion 11 are closely fitted, so that the fitting portion is further tightened by the elasticity of the outer portion 10 when the device 1 is mounted as described above. The displacement between the back plate 20 and the outer portion 10 is effectively prevented, and the device main body 1 is prevented from being inadvertently dropped from the protective case.

Further, the cross section of the lower (back side) side of the U-shaped outer portion 10 is formed to be slightly larger in thickness than the thickest portion of the back plate 20 and the apparatus main body 1 is mounted. When the protective case is placed on a table or the like, the hard member 21 on the surface is prevented from directly touching the surface of the table or the like, and the possibility that the surface of the hard member 21 is damaged by friction is reduced.

FIG. 8 is an enlarged cross-sectional view in which the cross-section of the portion surrounded by the circle Y in FIG. 4 is enlarged when the back plate 20 is a simple plate shape. The fitting relationship between the back plate 20 and the outer portion 10 is the same as in FIG.

FIG. 9 is a cross-sectional perspective view showing a cross section of the back plate 20. As described above, the back plate 20 has a structure in which the covering member 22 is bonded to the hard member 21 that forms the surface on the back side (exposed surface), and in this figure, the hard member 21 and the covering member 22 are separated. Indicates the state. The hard member 21 is formed to have a smooth step so as to rise to the back side in the vicinity of both ends of the outer edge portion, and the groove portion 23 is provided on the outer edge portion in parallel with the outer edge line. The substantially convex shape of the hard member 21 having such a step is not essential, and is a decorative process that adds a sense of quality and profoundness to the appearance of the protective case. For example, when a metal plate is used as the material of the hard member 21 Can be formed relatively easily by press working or the like. On the other hand, the cross-section of the covering material 22 is formed with a thin outer edge portion corresponding to the stepped shape of the hard member 21 and a thick portion other than the hard member 21, and adheres to the hard member 21 without a gap. As a result, the cross section of the back plate 20 is a smooth flat surface on the front side that is in close contact with the device main body 1, and as a whole forms a substantially convex shape that rises from the back side of the device main body. The reason why the covering material 22 is formed to have a substantially convex cross section is to prevent the possibility of causing a gap between the hard member 21 and separation, and the material used for this is soft plastic, silicon rubber, or the like. Thermoplastic polyurethane (TPU), which is softer than the sheet or plastic and harder than the silicone rubber, is suitable, but the material is not limited to these as long as it is easy to mold and exhibits the above effects.

FIG. 10 is an enlarged cross-sectional view in which a cross section of a portion surrounded by a circle Z in FIG. 4 is enlarged. A through hole 24 is provided in the back plate 20 at a position corresponding to the camera lens disposed on the back surface of the device body 1. The upper figure shows a state where the hard member 21 and the covering material 22 constituting the back plate 20 are bonded, and the lower figure shows a state where they are separated. Here, the covering material 22 has a cylindrical protrusion 26 in the through hole 24, while the hard member 21 has a hole 25 having a size corresponding to the outer diameter of the cylindrical protrusion 26. The projecting portion 26 penetrates through the hole 25 and the cylindrical cross section is exposed on the surface of the hard member 21. Therefore, when the back plate 20 is viewed from the back side, the through holes 24 are trimmed by the covering material 22, and exhibit a decorative effect that adds an accent to the appearance of the back plate 20. For this reason, it is desirable for the decoration effect that the material of the covering material 22 is selected so that the material and the color of the hard member 21 have a design contrast.

Since the hard member 21 forming the exposed surface of the back plate 20 is the most important member in the decorative effect of the protective case, surface decoration by various materials, surface processing, painting, and the like can be considered. For example, when the hard member 21 is made of metal, it is conceivable to use titanium or an alloy thereof that is lightweight, strong, and excellent in corrosion resistance. It is possible to express the texture of solid metal without painting or surface processing, or to apply unevenness pattern processing by so-called hairline processing or etching on the surface, and various coating techniques using advanced coating technology used for eyeglass frame processing Texture, color, and pattern painting may be applied. Further, when the “window” is opened by cutting the hard member 21 with various patterns, the covering material 22 is exposed through the “window”, so that a three-dimensional “watermark engraving” effect can be exhibited. Become.

As a material for the hard member 21, materials having various decorative effects other than metal can be used. For example, wood or decorative plates with lacquering, lacquering, inlaying, etc., leather attached with a hard core or directly attached to the covering, or exterior parts of automobiles for racing It is also conceivable to use a carbon fiber plate used.

By preparing the back plate 20 using various members as described above and the outer portion 10 of various colors, the user can customize the protective case of their favorite design by arbitrarily combining them, Needs to enjoy a variety of designs tailored to the mood of the TPO and users, while naturally having the function of protecting the original portable information device, but with a sense of luxury and high quality beyond the level of simple accessories. It becomes possible to satisfy.
