Patent Application
20150378451
The present invention relates to portable sheaths, and more particularly, to a sheath for containing a penlike device in a manner to enhance the portability thereof.
Portable electronic devices which come with a touchscreen are in wide use and are commonly commercially available in the form of tablets, smartphones, and notebook computers. To operate a portable electronic device, users touch icons and the keys of virtual keyboards displayed on a user interface provided on the touchscreen, using their fingertips, so as to execute software and apps installed on the portable electronic device. However, the foresaid prior art has drawbacks. It is likely that a user's fingertip is bigger than an icon or the keys of a virtual keyboard on the user interface of a portable electronic device, and in consequence the user's big fingertip are unlikely to touch any intended icon or key precisely. In winter, it can be too cold for bare fingers to touch a touchscreen outdoors. Human fingers are naturally oily even when thoroughly clean, and get dirty in the course of daily life. Oil and dirt from the fingers can build up on a touchscreen. Furthermore, not everyone can user their fingers, for example, in case of moderate orthopedic disabilities in the upper limbs. To overcome the aforesaid drawbacks of the prior art, users use styluses with their portable electronic device, because styluses have advantages over human fingers in the following aspects. Unlike fingers, styluses are not only precise but also have multiple tip designs. Styluses protect the touchscreen from scratches which might otherwise be caused by long sharp fingernails. Moreover, portable touchscreen-equipped electronic device users have a higher typing speed with styluses than with fingers.
However, most conventional portable electronic devices equipped with a touchscreen neither come with a stylus nor include any structure for receiving a stylus. As a result, users have to carry a stylus in order to operate the touchscreen by means of the stylus. Furthermore, conventional styluses are so small that users are likely to forget to bring a stylus or lose it. For the above reasons, the prior art brings inconvenience to the users.
In view of the aforesaid drawbacks of the prior art, it is an objective of the present invention to allow a stylus to be fastened to a portable electronic device equipped with a touchscreen such that users can carry the portable electronic device together with the stylus conveniently.
In order to achieve the above and other objectives, the present invention provides a portable sheath, comprising: a sheath body including an insertion portion; and a cord connected to the sheath body and adapted to fasten the sheath body to a data-related device.
Regarding the portable sheath in an embodiment of the present invention, the sheath body includes a soft outer layer and a support layer coupled to the soft outer layer.
Regarding the portable sheath in an embodiment of the present invention, the support layer is provided in form of one of a cardboard and a metal sheet.
Regarding the portable sheath in an embodiment of the present invention, a cleaning layer is disposed on the sheath body.
Regarding the portable sheath in an embodiment of the present invention, the cleaning layer is provided in form of a wiping fabric made of a flannel.
Regarding the portable sheath in an embodiment of the present invention, the insertion portion of the sheath body is pouch-shaped and has a closed bottom end.
Regarding the portable sheath in an embodiment of the present invention, the cord is elastic.
Regarding the portable sheath in an embodiment of the present invention, the sheath body and the cord are coupled together by means of machine sewing.
Regarding the portable sheath in an embodiment of the present invention, the sheath body and the cord are integrally formed as a unitary structure.
According to an embodiment of the present invention, a portable sheath comprises a sheath body into which a stylus can be inserted and thus contained therein. The portable sheath further comprises a cord which can be fastened to a data-related device, such that the stylus can be attached to the data-related device, thereby allowing a user to carry the data-related device together with the stylus conveniently.
Objectives, features, and advantages of the present invention are hereunder illustrated with specific embodiments in conjunction with the accompanying drawings, in which:

Referring to
In practice, the support layer 15 is provided in the form of a support board, such as a cardboard or a metal sheet, and adapted to reinforce the sheath body 10 and thus render the sheath body 10 rigid and non-deformable.
In practice, the cleaning layer 17 is provided in the form of a wiping fabric made of a flannel, and adapted to wipe dust and fingerprints from the touchscreen of the data-related device.
Hence, according to the present invention, the portable sheath 100 contains the penlike device 200 and is fastened to the data-related device, such that users are less likely to lose the penlike device 200 or forget to bring the penlike device 200.
For illustrative sake, in an embodiment of the present invention, the data-related device is a smartphone 310 (shown in
Referring to
Preferably, the stylus 200′ is retractable (not shown) to allow the users to determine whether to extend or retract, and by what extent, the stylus 200′ according to the user's handwriting gesture preferences. The retractable stylus 200′ has the following advantages: the stylus 200′ comes with one size (and particularly, one length) only and is for use with the portable sheath 100 which also comes with one size (and particularly, one length) only; and, as the stylus 200′ will still be applicable to the smartphone 310 even if the smartphone 310 has a shorter length than the maximum length of the stylus 200′, because the stylus 200′ is retractable and thus can be refracted before being mounted on the short smartphone 310. To sum up its advantages, the stylus 200′, which comes with one size (and particularly, one length) only, is applicable all data-related devices regardless of their size (and particularly, one length).
Referring to
In conclusion, according to an embodiment of the present invention, a portable sheath comprises a sheath body into which a stylus can be inserted and thus contained therein. The portable sheath further comprises a cord which can be fastened to a data-related device, such that the stylus can be attached to the data-related device, thereby allowing a user to carry the data-related device together with the stylus conveniently.
The present invention is disclosed above by preferred embodiments. However, persons skilled in the art should understand that the preferred embodiments are illustrative of the present invention only, but should not be interpreted as restrictive of the scope of the present invention. Hence, all equivalent modifications and replacements made to the aforesaid embodiments should fall within the scope of the present invention. Accordingly, the legal protection for the present invention should be defined by the appended claims.
