Description

FIELD OF THE INVENTION

The present invention relates to a protective cover unfolding and positioning device, in particular to the protective cover unfolding and positioning device with the features of a simple installation, an easy and convenient use, and capable of providing an innovative diversified way of unfolding and fixing a protected portable telecommunication product or electronic device, so as to achieve the effects of the convenient and efficient operation, use or viewing, and the whole protective cover has the features of a simple cost-effective manufacture and a handy and thin design for an easy carry and not occupying much space, and improves over the conventional devices of the same sort.

BACKGROUND OF THE INVENTION

As science and technology advance, portable telecommunication products and electronic devices such as digital media players (DMP), global positioning systems (GPS), tablet PCs, touch screen mobile phones using a light crystal display (LCD) and an organic light emitting diode (OLED) display as interfaces are developed and introduced to the market constantly.

In general, the telecommunication products or electronic devices come with a protective cover to provide an easy carry and reduce rubbing, collisions or damages. Most protective covers have a cover or bag for accommodating the telecommunication product or electronic device directly, or the telecommunication product or electronic device is designed to be able to combine with a protective cover directly. Although the design of the protective cover or bag can achieve the effect of protecting the telecommunication product or electronic device, it has a single function on practical application and cannot meet the user requirements. Therefore, the inventor of the present invention has developed “an improved protective cover” as disclosed in R.O.C. Pat. Application No. 99210050 and shown in FIGS. 1 to 4, wherein a telecommunication product or electronic device A has a stylish design capable of connecting, folding and unfolding a first protective plate 10 and a second protective plate 11 to protect the telecommunication product or electronic device A. The first protective plate 10 is provided for installing the telecommunication product or electronic device A and includes a folding portion B disposed on a transverse peripheral surface of the first protective plate 10 for dividing the first protective plate 10 into an upper support portion 101 and a lower support portion 102, and a positioning element 1011, 1021 installed at the upper and lower support portions 101, 102 separately for positioning the telecommunication product or electronic device A. The second protective plate 11 includes at least one transverse positioning slot 111 and a buckle loop 112 disposed at the periphery of the second protective plate 11, for latching and protecting the telecommunication product or electronic device A when the second protective plate 11 is folded and stacked onto the first protective plate 10.

When use, the first and second protective plates 10, 11 can be folded and stacked with each other to protect the telecommunication product or electronic device A (as shown in FIG. 3) and also can be unfolded to lift the first protective plate 10 upward, and then a lower end of the telecommunication product or electronic device A is separated from a lower support portion positioning element 1021 of the first protective plate 10 and plugged slantingly and fixed into any one of the positioning slots 111 of the second protective plate 11 to achieve the effect of disposing the telecommunication product or electronic device A obliquely to facilitate users' operations and improve the viewing effect (as shown in FIG. 4).

The transverse positioning slot 111 is formed on a peripheral surface of the second protective plate 11 for fixing the telecommunication product or electronic device A obliquely, so as to achieve the effect of a simple, easy and convenient operation, and such arrangement is welcome by users. However, the inventor of the present invention conducted further researches and experiments and developed an improved protective cover unfolding and positioning device to provide add-on values to the product. In other words, some necessary manufacturing procedures must be taken to form the transverse positioning slots 111, regardless of the quantity of the transverse positioning slots 111. The larger the quantity, the more complicated are the manufacturing procedures. These complicated manufacturing procedures often incur a higher cost. In addition, the telecommunication products or electronic devices A must be plugged into the transverse positioning slots 111 one by one before the effect of fixing the telecommunication products or electronic devices obliquely is achieved. In addition to the relatively slow operation, particularly the quantity and interval of the transverse positioning slots 111 directly limit the angle of disposing the telecommunication product or electronic device A, so that there will be limitation and inconvenience for users to operate or view the telecommunication product or electronic device A. To cope with the formation of the transverse positioning slots 111, the second protective plate 111 is thicker, and thus resulting in increased volume and clumsiness.

SUMMARY OF THE INVENTION

It is a primary objective of the present invention to overcome the aforementioned drawbacks of the prior art by providing a protective cover unfolding and positioning device, such that when the portable telecommunication product or electronic device is unfolded for use, the operation is simple, easy, quick, convenient and efficient, and the telecommunication product or electronic device can be fixed obliquely at a position to provide a more diversified and variable application, and the manufacture of the protective cover is simpler and cheaper, and the invention can save materials and improve the portability of the protective cover unfolding and positioning device.

To achieve the aforementioned and other objectives, the present invention provides a protective cover unfolding and positioning device, wherein a position restoring element is installed at a position of folding portion adjacent to the upper and lower support portions of the first protective plate, and the position restoring element provides a restoring resilience for bending and folding the upper and lower support portions by using the folding portion as a base.

The unfolded first protective plate is lifted upward to move a lower end of a telecommunication product or an electronic device to be disposed obliquely on a peripheral surface of a second protective plate peripheral surface, and when the upper and lower support portions of the first protective plate are folded with each other automatically at the folding portion, the weight of the telecommunication product or electronic device exerted onto the first protective plate upper and the lower support portions and the restoring resilience provided by the position restoring element to the upper and lower support portions assure that the obliquely disposed telecommunication product or electronic device is supported securely to maintain the positioning stability, and the angle of the oblique telecommunication product or electronic device can be adjusted freely to achieve the simple operation and convenient viewing effect, and the second protective plate does not require any positioning device corresponding to the telecommunication product or electronic device, and the whole protective cover can have a thin design to achieve the effects of saving materials, providing a handy device for an easy and convenient carry, and occupying not much space.
