DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

(7) Referring to FIG. 1 to FIG. 3, a support frame for a portable electronic device 4 in accordance with the present invention comprises a square frame body 1, a first support arm 2, and a second support arm 3. The lengths of the first support arm 2 and the second support arm 3 are adjustable. The portable electronic device 4, such as a smart phone, a tablet computer, a notebook computer, etc., can be held on the frame body 1. The inner edge of the frame body 1 defines a first side 11 and a second side 12 opposite to each other.

(8) The first support arm 2 includes a first casing plate 21 and a first inner plate 22. The first casing plate 21 is in a hollow shape. The first casing plate 21 has a first hollow space 23 therein and a first opening 24 at one end thereof. The first casing plate 21 is pivotally connected to the first side 11 of the frame body 1 with a pivot shaft 211, so that the first casing plate 21 is pivotal relative to the frame body 1. The first inner plate 22 is accommodated in the first hollow space 23. One end of the first inner plate 22 extends out of the first opening 24. The first inner plate 22 can be pulled out from the first opening 24 and is movable relative to the first casing plate 21.

(9) The first casing plate 21 and the first inner plate 22 have a relatively retaining structure. Two sides of the first inner plate 22 are provided with a plurality of first positioning portions, respectively. Each of two sides of the first casing plate 21 is provided with a first positioning member 25 corresponding to the first positioning portions. The first inner plate 22 can be retained by positioning the first positioning member 25 to one of the first positioning portions. In this embodiment, as shown in FIG. 4, the plurality of first positioning portions are spaced first engaging teeth 26. The first positioning member 25 is accommodated in a first accommodating room 212 of the first casing plate 21 and has a first engaging portion 251 extending toward the first engaging teeth 26. The first positioning member 25 has elasticity. The first engaging portion 251 is normally engaged with one of the first engaging teeth 26, so that the first casing plate 21 and the first inner plate 22 are relatively retained. When the first positioning member 25 is pressed, as shown in FIG. 5, the first positioning member 25 is deformed and disengaged from the first engaging teeth 26 to release the retaining state of the first casing plate 21 and the first inner plate 22. Accordingly, the length of the first support arm 2 can be adjusted by changing of the relative position of the first casing plate 21 and the first inner plate 22.

(10) As shown in FIG. 1 to FIG. 3, the second support arm 3 includes a second casing plate 31 and a second inner plate 32. The second casing plate 31 is in a hollow shape. The second casing plate 31 has a second hollow space 33 therein and a second opening 34 at one end thereof. The second casing plate 31 is pivotally connected to the second side 12 of the frame body 1 with a pivot shaft 311, so that the second casing plate 31 is pivotal relative to the frame body 1. The second inner plate 32 is accommodated in the second hollow space 33. One end of the second inner plate 32 extends out of the second opening 34 and is pivotally connected to the first inner plate 22 through a pivot shaft 30. The second inner plate 32 can be pulled out from the second opening 34 and is movable relative to the second casing plate 31.

(11) The second casing plate 31 and the second inner plate 32 have a relatively retaining structure. Two sides of the second inner plate 32 are provided with a plurality of second positioning portions, respectively. Each of two sides of the second casing plate 31 is provided with a second positioning member 35 corresponding to the second positioning portions. The second inner plate 32 can be retained by positioning the second positioning member 35 to one of the second positioning portions. In this embodiment, as shown in FIG. 4, the plurality of second positioning portions are spaced second engaging teeth 36. The second positioning member 35 is accommodated in a second accommodating room 312 of the second casing plate 31 and has a second engaging portion 351 extending toward the second engaging teeth 36. The second positioning member 35 has elasticity. The second engaging portion 351 is normally engaged with one of the second engaging teeth 36, so that the second casing plate 31 and the second inner plate 32 are relatively retained. When the second positioning member 35 is pressed, as shown in FIG. 5, the second positioning member 35 is deformed and disengaged from the second engaging teeth 36 to release the retaining state of the second casing plate 31 and the second inner plate 32. Accordingly, the length of the second support arm 3 can be adjusted by changing the relative position of the second casing plate 31 and the second inner plate 32.

(12) With the above structure, the present invention can change the angle of supporting the electronic device 4 by adjusting the length of the first support arm 2 or the second support arm 3. In detail, when the first casing plate 21 and the second casing plate 31 are pivoted and opened relative to the frame body 1, the corresponding inner plate can be pulled out from the first casing plate 21 or the second casing plate 31 to adjust the length of the first support arm 2 or the second support arm 3. For example, as shown in FIG. 6, only the first inner plate 22 is pulled out from the first casing plate 21. As shown in FIG. 7, the first inner plate 22 and the second inner plate 32 are pulled out from the first casing plate 21 and the second casing plate 31, respectively. Accordingly, the included angle between the first support arm 2 and the second support arm 3 can be changed, and thus the angle of supporting the electronic device 4 is changed.

(13) Furthermore, as shown in FIG. 1 and FIG. 2, the first casing plate 21, the second casing plate 31, the first inner plate 22 and the second inner plate 32 are provided with recessed control portions 27, 28, 37, 38 respectively to facilitate the operation control.

(14) The advantage of the present invention is that the first support arm 2 and the second support arm 3 can use the multiple positioning portions thereof to achieve multi-stage length adjustment, so that the supporting angle can be changed for different environments when in use. On the other hand, the means for adjusting the length of the first support arm 2 and the second support arm 3 is that the inner plates 22, 32 are received in the casing plates 21, 31, so that the overall height of the support frame is not affected, meeting the trend of thinning of electronic devices.

(15) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
