Stylus having magnifying lens

Abstract

A stylus for a portable electronic device includes a main body, a nib, and a lens. The main body defines a chamber in an end, the nib and the lens are connected to the other end of the main body. A space if formed between the nib and the lens. An extending direction of the nib intersects with an extending direction of the lens to form an angle, and the angle is in a range from 0°-90°.

BACKGROUND

1. Technical Field

This disclosure relates to a stylus for portable electronic devices.

2. Description of Related Art

Styluses are often used with touch screens of electronic devices. A stylus may include a main body and a nib portion formed at one end of the main body, and be configured for comfortably held and used by an average user. However, the typical pen-like configuration is often difficult for certain types of users to accurately use, such as users with vision deficiencies.

Therefore, there is room for improvement within the art.

BRIEF DESCRIPTION OF THE DRAWINGS

Many aspects of the stylus can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the multifunctional case.

FIG. 1 is an integral schematic view of a stylus according to an exemplary embodiment.

FIG. 2 is similar to FIG. 1, but viewed from another angle.

FIG. 3 is also similar to FIG. 1, but viewed from yet another angle.

DETAILED DESCRIPTION

FIGS. 1, 2 and 3 show an exemplary stylus 100 for a touch screen of a portable electronic device for inputting information, etc. The stylus 100 includes a main body 10, a nib 13, and a lens 15. The nib 13 and the lens 15 are connected to the same end of the main body 10, and a space 135 is defined between the nib 13 and the lens 15. The extending direction B-B of the nib 13 intersects with the extending direction A-A of the lens 15 to form an angle α in a range of 0°-90°.

The main body 10 is generally tubular and can be made of plastic materials such as Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), etc. The main body 10 includes an opening end 101 and an opposite sealing end 103. The opening end 101 defines a chamber 105 extending to the sealing end 103 and two opposite cutouts 107. The chamber 105, is configured for receiving and holding a finger of a user. The cutouts 107 communicate with the chamber 105. The cutouts 107 facilitate insertion of a user's finger into the chamber 105 to adjust the position of the finger in the chamber 105. The sealing end 103 has an irregular spherical surface 1031 including a top side surface 1032 and an opposite bottom side surface 1033.

The nib 13 is a tiny post and protrudes from the bottom side surface 1033 of the spherical surface 1031 for touching the screen of the portable electronic device. The nib 13 can be made of elastic plastic materials such as Thermo Plastic Urethane (TPU), to prevent wear of the screen from contact by the nib 13.

The lens 15 generally has an elongated shape. The lens 15 extends from the top side surface 1032 of the spherical surface 1031 and can substantially shield the nib 13. The lens 15 can be a concave lens to act as a magnifying lens for users to better see characters on the display written using the nib 13.

To use the stylus 100, a user inserts their finger into the chamber 105 to wear the stylus 100, and thus the nib 13 can touch and write characters on the screen by manipulation of the finger. Meanwhile, the user can clearly see characters on the screen because of magnification by the lens 15, helping the user to have greater accuracy when using the stylus 100.

It is to be understood that even though numerous characteristics and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
