Description

[Technical Field]

[0001] The present invention relates to an air cushion personal digital assistant case. [Background technology]

[0002] Conventionally, in order to protect the mobile information terminal case 100 from impact, a number of cavities a are formed in the inside part of the four-circumferential frame part F. Although a part of the cavity a forming part (partition wall ww, arch wall w3) is in contact with the back of the mobile information terminal 99, the cavity a is not sealed, and there is a drawback in the conventional technology in that when an impact is received, the compressive force of the air in the cavity a (the effect of the air cushion) cannot be expected to mitigate the impact. In addition, in the past, when protecting the mobile information terminal case 100 from impacts such as dropping, a hollow section a that is in communication with the outside air air0 is provided on the inside part of the four-circumferential frame section F of the mobile information terminal case 100, and adjacent hollow sections a are separated by partition walls ww, thereby reducing the contact surface between the mobile information terminal case 100 that is protected from impact and the four-circumferential frame section F, creating a flexible structure and absorbing the impact. However, from a design perspective, if the four-way frame F were made transparent (or translucent), the outline of the partition wall ww of the hollow section a would stand out like dirt, resulting in a poor appearance (Figures 9 and 11). Furthermore, the recent trend in conventional technology is to make the four-way frame portion F as thin as possible, and it has been pointed out that the provision of a hollow portion a in the inner part of the four-way frame portion F that is in communication with the outside air air0 weakens the structure against impacts, which is a drawback of the conventional technology. Furthermore, in the past, in order to protect the mobile information terminal case 100 from impact, multiple hollow portions a were provided in the inner part of the four-circumferential frame portion F, which weakened the strength of the impact absorbing structure and forced the thickness (thickness in the outward direction) of the four-circumferential frame portion F to increase, which had the disadvantage of not being able to achieve the effect of the smart design of the mobile information terminal case 100. Here, the prior art is as follows: The conventional mobile information terminal case 100 is This portable information terminal case 100 is comprised of a four-sided frame portion F, a transparent bottom plate G, a portable information terminal case storage portion S, and a plurality of hollow portions a arranged along the longitudinal direction of the four-sided frame portion F, with the portable information terminal case storage portion S being surrounded by the four-sided frame portion F and the transparent bottom plate G. The hollow portions a are opened from the inside to the outside of the four-sided frame portion F, with opening a0 facing inward, and five sides except for opening a0 on the inside of the four-sided frame portion F are surrounded by walls w of the four-sided frame portion (Figures 6 to 11). DISCLOSURE OF THE INVENTION

Summary of the Invention [Problem to be solved by the invention]

[0005] First problem to be solved by this invention The first problem to be solved by the present invention is: To provide an air cushion portable information terminal case 100 characterized in that a four-periphery frame part F of the portable information terminal case 100 is covered with an outer four-periphery frame part FO to trap air therein and form a sealed air cushion part A. Second problem to be solved by this invention The second problem to be solved by the present invention is: To provide an air cushion mobile information terminal case 100 that eliminates the drawback that the outline of the partition wall ww that separates the hollow portion a of the four-circumferential frame portion F of the mobile information terminal case 100 (particularly when the four-circumferential frame portion F is made of a transparent or semi-transparent body) stands out like dirt, resulting in a poor appearance (Figs. 9 and 11). That is, the second problem to be solved by the present invention is: The object of the present invention is to provide an air cushion mobile information terminal case 100 that eliminates the drawback that, empirically, in the case of a transparent or semi-transparent four-sided frame portion F, the outline of the partition wall ww that separates the hollow portion a stands out clearly like dirt, resulting in a poor appearance (Figures 9 and 11). Third problem to be solved by this invention The third problem that the present invention aims to solve is: The object of the present invention is to provide an air cushion portable information terminal case 100 which eliminates the drawback of the prior art that the case is weak in strength against impact by providing a hollow portion a which is in communication with the outside air air0 in the inner part of the four-circumferential frame portion F of the portable information terminal case 100. Fourth problem to be solved by this invention The fourth problem to be solved by the present invention is: To provide an air cushion portable information terminal case 100 characterized in that the thickness (thickness toward the outside) of the four-perimeter frame part F of the portable information terminal case 100 is kept thin (while maintaining a smart design) and is joined to cover the four-perimeter frame part FO (in the case of a transparent, semi-transparent or opaque body), and air is trapped inside to form a sealed air cushion part A. ******************************************************* <Explanation of terms in the prior art> ******************************************************* Prior art mobile information terminal case 100 The conventional mobile information terminal case 100 is This portable information terminal case 100 is comprised of a four-sided frame portion F, a transparent bottom plate G, a portable information terminal case storage portion S, and a plurality of hollow portions a arranged along the longitudinal direction of the four-sided frame portion F, with the portable information terminal case storage portion S being surrounded by the four-sided frame portion F and the transparent bottom plate G. The hollow portions a are opened from the inside to the outside of the four-sided frame portion F, with opening a0 facing inward, and five sides except for opening a0 on the inside of the four-sided frame portion F are surrounded by walls w of the four-sided frame portion (Figures 6 to 11). ******************************************************* The four-perimeter frame portion F is a component of the conventional mobile information terminal case 100, and refers to the four-perimeter portion that holds the transparent bottom plate G. When combined with the transparent bottom plate G, this portion forms the mobile information terminal storage section S. Two or more hollow portions a are formed inside the four-sided frame portion F, and adjacent hollow portions a are separated by a partition wall ww (FIG. 6(A), FIGS. 9 to 11). The four-sided frame portion F is composed of a pair of long frame portions F1 and a pair of short frame portions F2. The length L1 (cm) of the long frame portion F1 is longer than the length L2 (cm) of the short frame portion F2. The transparent bottom plate G is the same as the <Explanation of terms in the present invention>. The portable information terminal case storage section S is the same as the <Explanation of terms in this invention>. The hollow portion a is a recessed portion that extends from the inside to the outside of the frame portion F, with the opening a0 facing inward. The hollow portion a is surrounded on five sides by the walls w of the frame portion F, excluding the opening a0 on the inside of the frame portion F. Here, "bonding" refers to the joining of the components of the present invention into one. For example, the components include a four-sided frame F and a transparent bottom plate G, and this set of components is bonded together. Bonding includes bonding by adhesion using an adhesive or the like (adhesive bonding), and in the present invention, surface bonding, in which surfaces are bonded together, is considered to increase the bonding strength (adhesion strength). A plurality of hollow portions a are formed along the longitudinal direction of the four-periphery frame portion F, and adjacent hollow portions a are separated by partition walls ww. Although the opening a0 inside the hollow portion a comes into contact with the back of the mobile information terminal 99 when the mobile information terminal 99 is stored in the mobile information terminal case 100, the air in the hollow portion a is in communication with the outside air air0 and does not function as an air cushion. From the above, the hollow portion a is also referred to as a recessed portion a because it communicates with the outside air air0. The opening a0 is the opening of the hollow portion a located inside the hollow portion a (in the case where the mobile information terminal 99 is stored, the opening is located close to the mobile information terminal 99) (FIG. 11). Wall w refers to the wall of cavity a. Here, wall w is composed of two partition walls ww and one arch wall w3 (Figure 11). The arch wall w3 refers to the wall w of the cavity a, which is arch-shaped and spans the opening a0. The cavity a has an arch wall w3, which indicates that the cavity a is not a through recess. The arch wall w3 and the partition wall ww are perpendicular to each other (Fig. 11). "The portable information terminal case storage section S is configured to be surrounded by a four-sided frame section F and a transparent bottom plate G" is the same as <Explanation of terms in this invention>. The terms "transparent body" and "semi-transparent body" are the same as those in the <Terminology in the present invention>. The walls w (of the four circumferential frame portions) are components of the conventional mobile information terminal case 100, and refer to the five walls surrounding the hollow portion a, excluding the opening a0 inside the circumferential frame portion F. The five walls surrounding the hollow portion a, excluding the opening a0 inside the circumferential frame portion F, are composed of two partition walls ww and one arch wall w3 (Figure 11). Partition wall ww refers to the wall that separates adjacent cavity sections a within the four-sided frame section F (Figure 11). * Outside air air0 is the same as <Explanation of terms in this invention>. "The portable information terminal case storage section S is configured to be surrounded by a four-sided frame section F and a transparent bottom plate G" is the same as <Explanation of terms in this invention>. - "To provide an air cushion mobile information terminal case 100 that eliminates the drawback that the outline of the partition wall ww that separates the hollow portion a of the four-circumferential frame portion F of the mobile information terminal case 100 (particularly when the four-circumferential frame portion is transparent or translucent) stands out like dirt, resulting in a poor appearance." (Second problem) means "The second problem is to eliminate the drawback that, in the case of a four-circumferential frame portion F that is transparent or translucent, the outline of the partition wall ww that separates the hollow portion a, empirically, stands out like dirt, resulting in a poor appearance." (Pay attention to the outline of the partition wall ww in Figure 9.) Figure 9 shows the case where the frame portion is made of a transparent material, and it can be seen that the recess provided in the frame portion F, i.e., the outline of the hollow portion a, stands out from the outside like dirt, which is a drawback that makes the product look bad. ******************************************************* <Relationship between the XYZ coordinate system (in the prior art) and the six views (front view, rear view, top view, bottom view, left side view, right side view)> is the same as <Explanation of terms in the present invention>. ******************************************************* [Means for solving the problem]

We have already defined the (right-handed) XYZ coordinate system in <About the (right-handed) XYZ coordinate system> (Figure 12). In this XYZ coordinate system, six views (front view, back view, top view, bottom view, left side view, right side view) are defined as follows (Figure 12). Of the six views, the front view will be first defined. The view seen by an observer at the front of the mobile information terminal case 100 observing the mobile information terminal case 100 at the rear side is defined as the front view (the X direction is from the paper surface to the back side of the paper).

The terminal case is shown in Figs. 1 to 5, in which the frame F is opaque (shown by hatching), and the outer frame FO and transparent bottom plate G are transparent. In other words, the terminal case is shown as it appears when observed from the outside. In other words, the hatched portion corresponds to the frame F. Here, "bonding" refers to the joining of the components of the present invention into one. For example, the components include the four-circumference frame portion F and the outer four-circumference frame portion FO, and the four-circumference frame portion F and the transparent bottom plate G, and these two sets of components are bonded together. Bonding includes bonding by adhesion using an adhesive or the like (adhesive bonding), and in the present invention, surface bonding, in which surfaces are bonded together, is considered to increase the bonding strength (adhesion strength). The air cushion mobile information terminal case 100 is characterized in that the four-perimeter frame portion F is joined so as to cover the outer four-perimeter frame portion FO, and air is trapped inside to form a sealed air cushion portion A. This is the present invention in which the characteristic constituent element of the above mobile information terminal case 100 is added, in which the four-perimeter frame portion F is joined so as to cover the outer four-perimeter frame portion FO, and air is trapped inside to form a sealed air cushion portion A (Figures 1 to 5). The four-perimeter frame portion F is a component of the mobile information terminal case 100 and refers to the four-perimeter portion that holds the transparent bottom plate G. When combined with the transparent bottom plate G, it forms the mobile information terminal storage section S. Furthermore, the four-perimeter frame portion F is combined with the outer four-perimeter frame portion FO to cover it, trapping air inside and sealing it, forming the air cushion portion A. The air cushion portion A is the portion that provides the shock absorbing function of the present invention. The four-sided frame portion F is composed of a pair of long frame portions F1 and a pair of short frame portions F2. The length L1 (cm) of the long frame portion F1 is longer than the length L2 (cm) of the short frame portion F2. The longitudinal frame portion F1 of the four-way frame portion F refers to a pair of longitudinal frame portions of the four-way frame portion F. The long frame portion F2 of the four-sided frame portion F refers to a pair of short frame portions of the four-sided frame portion F. The outer frame portion FO is a component of the mobile information terminal case 100, and is slightly larger than the frame portion F so that it can cover the frame portion F from the outside, and is designed so that both ends are flush with each other. The frame portion F and the outer frame portion FO, and the frame portion F and the transparent bottom plate G are joined together, and the mobile information terminal case storage section S is configured to be surrounded by the frame portion F and the transparent bottom plate G. The outer frame portion FO is composed of a pair of long frame portions FO1 and a pair of short frame portions FO2. In other words, it has a ring-shaped, integrated structure composed of a pair of long frame portions FO1 and a pair of short frame portions FO2, and the outer frame portion FO can be injection molded and mass-produced, which has resulted in a remarkable effect that would have been unforeseen by those skilled in the art: it is possible to provide an inexpensive mobile information terminal case 100. The length L1 (cm) of the long frame portion FO1 is longer than the length L2 (cm) of the short frame portion FO2. The longitudinal frame portion FO1 (longitudinal frame portion FO1) of the outer four-circumferential frame portion FO refers to a pair of longitudinal frame portions of the four-circumferential frame portion FO. The long frame portion FO2 (short frame portion FO1) of the outer four-circumference frame portion FO refers to a pair of short frame portions of the four-circumference frame portion FO. The mobile information terminal case storage section S is a storage space surrounded by a four-sided frame section F and a transparent bottom plate G. The transparent bottom plate G is a component of the mobile information terminal case 100, and is a component that forms the mobile information terminal storage section S, which is the section that stores the mobile information terminal 99, by combining the four-circumferential frame section F and the transparent bottom plate G. The transparent bottom plate G is a transparent body that is provided so that when a mobile information terminal 99 is stored in the mobile information terminal case 100, the decorative screen Dg on the back of the mobile information terminal can be seen from the back side of the case by combining the four-sided frame portion F with the transparent body G. The transparent bottom plate G corresponds to the glass plate of a picture frame for displaying a picture, etc. The picture frame corresponds to the four-sided frame portion F, and the picture, etc. corresponds to the decorative screen Dg. The air cushion part A is the part that has the shock absorbing function of the present invention, and is the part that is sealed by joining the outer four-circumferential frame part FO so as to cover the four-circumferential frame part F, trapping air inside (Figure 1 (A), Figures 5 (A) to (D)). The air cushion portion A has a ring-shaped integral structure similar to the air portion of a rubber tire of a bicycle, for example. The air refers to the air trapped in the air cushion portion A in the mobile information terminal case 100 when the outer frame portion FO is joined to cover the outer frame portion F. * "By joining the four-perimeter frame part F so as to cover it with the outer four-perimeter frame part FO" means "by joining both ends of the four-perimeter frame part F and the outer four-perimeter frame part FO along the four perimeter, the four-perimeter frame part F is surrounded by the transparent bottom plate G, and the outer four-perimeter frame part FO is sandwiched between the four-perimeter frame part F and the transparent bottom plate G, and air is trapped and sealed between them to form the air cushion part A."
