Title: Adjustable table stand and device using the same

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to devices, and particularly to a device with a table stand which is adjustable to select a desirable viewing angle. 
     2. Description of Related Art 
     Some devices are equipped with a support such as a table stand that swivels out from the device to support the device on a flat surface. However, most current table stands are not adjustable or not easily adjustable, and the table stands fold out at a predetermined angle with the device. As a result, the viewing angle for different users cannot be adjusted. 
     Therefore, there is room for improvement in the art.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure will now be described in detail with reference to the drawings. 
     Referring to  FIG. 1 , a device  10  includes a main body  100  and a table stand  200  connected to the main body  100 . The main body  100  includes a front housing  110  with a display panel (not shown) and a rear housing  130  engaged with the front housing  110 . In this embodiment, the device  10  may be a digital photo frame, a mobile internet device, or a GPS device. 
     Referring to  FIG. 2 , the rear housing  130  includes an outer surface  131 . The outer surface  131  is partially recesses to define a receiving portion  140  for receiving the table stand  200 . 
     The receiving portion  140  includes a bottom surface  141  and side surfaces  142  surrounding the bottom surface  141 . The side surface  142  further includes an upper side  1421 , a lower side  1422 , a left side  1423  and a right side  1424 . At least one of the left side  1423  and the right side  1424  defines a guiding slot  1426 . In this embodiment, both the left and the right side  1423  and  1421  define a guiding slot  1426 . The receiving portion  140  further defines two pivot holes  1427  at the end of the left side  1423  and the right side  1424  respectively. 
     A plurality of elastic trapezoidal locking portions  143  protrudes from the bottom surface  141 , and is arranged in a line along the longitudinal direction of the receiving portion  140 . The trapezoidal retaining portions  143  are parallel with each other, and each two adjacent trapezoidal locking portions  143  define a locking groove  145 . The locking groove  145  is used for locking the table stand  200  to prevent the table stand  200  from sliding with respect to the main body  100 . The locking portion  143  includes an upper portion  1431  and a lower portion  1432 . The upper part  1431  defines a slope which is used for guiding the table stand  200  to insert the locking groove  145  easily. The lower part of the locking part  143  is used for locking the table stand  200  in one of the locking grooves  145 . The locking portions  143  are made of elastic material, so that the locking portions  143  can deforms elastically. 
     The table stand  200  includes a first supporting element  210 , a second supporting element  230 , a first pivot  250  and at least one retaining pin  270 . 
     The first supporting element  210  is a retaining board which is a substantially rectangular plate. The retaining board  210  includes a first end  213  and a second end  215  opposite to the first end  213 . The first end  213  defines two first pivot holes  216 . The second end  215  defines at least one second pivot hole  217 . Opposite ends of each the retaining pin  270  are respectively received in the second pivot hole  217  and the guiding slot  1426 , thus the second end  215  of the retaining board  210  is able to slide in the receiving portion  140 . 
     The second supporting element  230  is a turning board which is a substantially rectangular plate. The turning board  230  includes a third end  231  and a fourth end  234  opposite to the third end  231 . The fourth end  234  defines a third pivot hole  235 . The first pivot  250  extends through the first pivot holes  216  and the third pivot holes  235  to rotatably connect the turning board  230  with the retaining board  210 . Two second pivots  233  are coaxially located respectively at the opposite sides of the third end  231 . The third end  231  further defines two openings  232 , such that the third end  231  can be deformed. The second pivot  233  inserts in the pivot holes  1427  of the rear housing  130  via the deformation of the third end  232 , thus the turning board is capable of rotating with respect to the rear housing  130 . 
     To provide support for the main body  100 , the retaining board  210  and the turning board  230  are rotated relative to the main body  100  to a support position. The third end  231  is inserted into the pivot holes  1427  of the receiving portion  140 . The retaining pin  270  is slidably received in the guiding slot  1426  such that the second end  215  of the retaining board  210  is received in one of the locking grooves, thus an angle is defined between the retaining board  210  and the turning board  230 . As such, the table stand  200  can be fixed and defines an angle with respect to the main body  100 . 
     Further referring to  FIG. 3 , the angle between the table stand  200  and the main body  100  can be adjusted via fixing the second end  215  of the retaining board  210  in a different locking groove  145 . The retaining pin  270  moves in the guiding slot  1426  so that the retaining board  210  inserts from one of the locking grooves  145  to another one. Thereby, the main body  100  can be placed at different appropriate viewing angles. Referring to  FIG. 4 , the table stand  200  can be rotated to be received in the receiving portion  140  if the main body  100  does not need to be supported. 
     While various exemplary and preferred embodiments have been described, it is to be understood that the disclosure is not limited thereto. To the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
