Abstract

An auxiliary fastening apparatus for engaging with tablet electronic device is provided, including a receiving unit, an angle adjustment mechanism and a support unit. The apparatus may further include an auxiliary belt. The receiving unit is for placing the tablet PC on, and the angle adjustment mechanism and the support unit are to enable the receiving unit to stand in either portrait or landscape mode. The auxiliary belt can be wrapped around the wrist to prevent the handheld tablet PC from slipping and falling to the ground. The unique structure of the support unit allows the tablet PC to tilt a small angle when placed on a desk top for convenient use. The auxiliary fastening apparatus of the present invention provides convenient use of the tablet PC in various occasions.

Claims

1. An auxiliary fastening apparatus, for engaging to a tablet electronic device, comprising:

a receiving unit, having a large-area disk, with a plurality of protruding clappers on a circumference of said disk, a rear surface of said disk being a back of said receiving unit;

an angle adjustment mechanism, formed on the back of said receiving unit, for enabling an angle adjustment; and

a support unit coupled to said angle adjustment mechanism, said support unit forming an angle with the back of said receiving unit when flipped up, said angle adjustment mechanism enabling said support unit to be angularly adjusted with the back of said receiving unit, said support unit comprising a support element, a connection element and a buckle element, said support element being connected to said buckle element via said connection element, said connection element being made of a soft material to allow said connection element to be bent at a large angle, one end of said support element being coupled to said angle adjustment mechanism to serve as a support frame of said support unit, a side of said buckle element disposed away from a connection to said connection element forming a buckle plate having a shape bent facing towards said receiving unit, said buckle plate being adapted to buckle to a side of said receiving unit, wherein when said connection element is bent, said buckle element is close to said support element.

2. The auxiliary fastening apparatus as claimed in claim 1, wherein said plurality of protruding clappers are formed on at least three sides of said receiving unit.

3. The auxiliary fastening apparatus as claimed in claim 1, wherein said plurality of protruding clappers are bent and formed on four corners of said receiving unit.

4. The auxiliary fastening apparatus as claimed in claim 1, wherein said angle adjustment mechanism further comprising an axial element, a rotation element and a resilient push obstruct element;

wherein said axial element protrudes from a central region of the back of said receiving unit, an inside of said axial element forming a housing space to accommodate resilient push obstruct element, said resilient push obstruct element having a protruding tooth extending to an outside of said axial element, said rotation element having a ring and an inner wall of said ring forming an inner ring tooth, said inner ring tooth being sheathed outside of said axial element, and said protruding tooth matching to engage said inner ring tooth.

5. The auxiliary fastening apparatus as claimed in claim 1, wherein the central region of the back of said receiving unit forms at least an engaging trench for providing a connection to other connection devices.

6. The auxiliary fastening apparatus as claimed in claim 5, wherein said engaging trench is formed on a lid fastened to said axial element on the back of said receiving unit.

9. The auxiliary fastening apparatus as claimed in claim 1, further comprising a restrictive element connected between said support unit and said angle adjustment mechanism, said restrictive element maintaining an angle and relative position between said support unit and said angle adjustment mechanism after said support unit is flipped up.

7. An auxiliary fastening apparatus, for engaging to a tablet electronic device, comprising:

a receiving unit, having a large-area disk, with a plurality of protruding clappers on a circumference of said disk, a rear surface of said disk being a back of said receiving unit;
