Description
The present invention relates to a case for a tablet PC, and more particularly, to a case for a tablet PC that can protect a smartphone or tablet PC, and can be placed on a desk at an appropriate angle for ease of use.
In general, tablet PCs have a handwriting recognition function, which enables users to input text or pictures into a word file or office through pen input, and to access the Internet from anywhere via wireless LAN. All.
Recent advances in computer and wireless network technology have enabled palm-sized tablet PCs to perform as comparable to desktop or laptop computers. The spread of tablet PCs is increasing due to the increase in popularity.
In particular, with the launch of high-end tablet PCs from global companies such as the iPad and Galaxy Tab, the demand is expected to explode.
However, as PCs increase in size due to miniaturization, the possibility of dropping or colliding with other objects increases.
Complex and sophisticated IT devices, such as tablet PCs, are more likely to fail when an external shock is applied due to a drop, especially when the core parts are damaged, such as when the LCD screen is broken due to an impact. Is lost, causing considerable damage. In addition, there is a greater possibility of scratching the surface when it comes into contact with or bumps into another object or a buckle attached to a user's clothing or an object housed in a bag.
On the other hand, the tablet PC is mainly used for the purpose of the Internet or video viewing, and especially in the case of video viewing, it is necessary to use it at an oblique angle on a desk or a flat floor surface.
In this regard, the applicant has filed Korean Utility Model Registration Application No. 20-2010-0011351.
The prior art is provided with an auxiliary storage unit with a cover on the back of the PC storage to accommodate the stylus fan, gender or earphones, as well as to open the storage cover to perform the support function tablet The PC was set up at an angle.
However, the prior art requires a lot of manufacturing labor because the cover is to be rotatably coupled, there is a problem that the product unit price will increase.
The present invention has been devised to solve the above problems of the prior art, without having a separate support means, by using a portion of the case as a support means to reduce the manufacturing labor, so that the volume can be concise The purpose is to provide a tablet PC case.
An object of the present invention described above, the storage unit is accommodated tablet PC; A main cover connected to one side of the housing and covered to protect the LCD screen of the tablet PC; A first connector connecting the housing and the main cover; An end cover connected to one side of the main cover and covered on an outer surface of the main cover; And a second connecting portion connecting the main cover and the end cover, wherein one side of the rear side of the housing is formed with an insertion groove into which an end of the end cover is inserted, and the end cover is coupled to the insertion groove of the housing. And it can be achieved by a tablet PC case, characterized in that the main cover has an inclination angle.
The end cover is formed to be curved portion is connected to the second connecting portion is formed curved portion, characterized in that the width is narrowed toward the other end.
The second connection portion is characterized in that made of a soft material to be extensible.
One side of the main cover is characterized in that the hole is formed to pass through the earphone string.
The hole is characterized in that a thin plate having a slit into which the earphone string is fitted.
The accommodating part may have a stepped portion formed at an edge thereof to be in close contact with the side surface of the tablet PC so as to exert a fixing force.
According to the present invention, the end cover is bent backward to be coupled to the rear of the storage unit to have an inclination angle suitable for the use of the tablet PC, so that it is convenient to use, the configuration is simple, and there is an effect of reducing the manufacturing labor.
1 is a perspective view of a tablet PC case according to the present invention,
2 is a rear view of the tablet PC case according to the present invention,
3 is a perspective view showing a state of use of the tablet PC case according to the present invention,
Figure 4 is a side view showing a state of use of the tablet PC case according to the present invention.
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
1 is a perspective view of a tablet PC case according to the present invention, Figure 2 is a rear view of the tablet PC case according to the present invention, Figure 3 is a perspective view showing a state of use of the tablet PC case according to the present invention 4 is a side view showing a state of use of the tablet PC case according to the present invention.
As shown in Figures 1 to 4, the case for a tablet PC according to the present invention (A), the receiving portion (1) that the tablet PC 100 is accommodated; A main cover 2 connected to one side of the accommodating part 1 and covered to protect the LCD screen of the tablet PC 100; A first connection part 3 connecting the accommodating part 1 and the main cover 2; An end cover 4 connected to one side of the main cover 2 and covered by an outer surface of the main cover 2; It comprises a second connecting portion 5 for connecting the main cover 2 and the end cover (4).
In addition, the rear side of the housing 1 is formed with an insertion groove 16 into which the end of the end cover 4 is inserted so that the end cover 4 is coupled to the insertion groove 16 of the housing 1. The payment part 1 and the main cover 2 have an inclination angle.
The accommodating part 1 is manufactured in the same shape as the shape of the tablet PC 100, is formed in a substantially rectangular shape, and the stepped portion 12 is formed at the edge of the tablet PC 100 so as to be firmly fixed.
Step 12 is particularly formed in the corner portion to be in close contact with the side and the edge of the tablet PC (100).
An insertion groove 16 is formed on the rear surface of the accommodating part 1 to have a predetermined length so that the end of the end cover 4 is inserted.
The main cover 2 is manufactured in the same area and shape as that of the accommodating part 1, and the inner cover is formed of molten or other soft material because it must be in contact with the LCD screen.
On one side of the main cover (2) is formed a hole 6 to pass through the earphone string. Since the earphone string is slid outward and shakes easily, the thin plate 7 having a slit 72 into which the earphone string is fitted is formed in the hole 6 so that the earphone string can be fixed by improving it.
The end cover 4 is formed to be connected to one end of the main cover 2 and is covered on the outer surface of the accommodating part 1 so that the tablet PC 100 can be wrapped so as not to be separated.
The end cover 4 is formed to be curved to the portion connected to the second connecting portion 5, the curved portion 42 is formed, the width is narrowed toward the other end.
The first and second connection parts 3 and 5 are made of a soft material so as to be extensible.
One side of the end cover 4, that is, the portion connected to the second connecting portion 5 may be formed in an arc shape to be in close contact with the outer surface of the accommodating portion 1 without being excited.
Referring to the use of the present invention configured as described above is as follows.
Looking at the case of storage, the tablet PC 100 is accommodated in the accommodating part 1, the main cover 2 is covered, and then the end cover 4 is brought into close contact with the outer surface of the main cover 2 to be completely wrapped.
On the other hand, when the tablet PC 100 is placed on a desk and used, the main cover 2 is rolled back to the rear of the accommodating part 1, and then the end cover 4 is swung upward, and the end thereof is inserted into the accommodating part 1. When the groove 16 is inserted into the groove 16, the main cover 2 and the housing 1 have a predetermined inclination angle.
Therefore, since the tablet PC 100 accommodated in the storage unit 1 may have an inclination angle suitable for work, it may be convenient to use and an appropriate viewing angle may be secured.
Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such changes and modifications being attached It is obvious that the claims belong to the claims.
