Description:
BACKGROUND OF THE INVENTION  
         [0001]    (1) Field of the Invention  
           [0002]    This invention relates to a supporting frame structure, and more particularly to a base that is used to support a portable device assembled with a supporting frame. By the use of hinges of the supporting frame and a lifting frame as well as a sliding track groove on the base, the supporting frame can be easily lifted up by one single-direction movement to a fixed angle to complete the buildup and placement.  
           [0003]    (2) Description of the Prior Art  
           [0004]    Generally speaking, most traditional chargers use a concave trough at the bottom part to support the base of the recharging device. The concave trough is restricted by the external appearance and internal mechanisms to cause the device lack proper support during the recharging duration and can easily become loose, fall down, or have a bad connection if encounters an external force, which greatly compromises the intended function of the charger. Please refer to FIG. 1, a schematic structure view of a prior charger, which includes a base  1 , and the base  1  further includes a concave trough at the bottom  2 , where the concave trough at the bottom  2  is used to accommodate the recharging device. The base further includes a display unit  3  to inform user operation status during recharging.  
           [0005]    As stated above, the device is placed in the concave trough at the bottom  2  during the actual recharging duration. Because of its improper design, the concave trough at the bottom  2  might not be able to provide enough support for the recharging device, a bad connection between the device and the charger might occur with a mere touch and interrupts the recharging task or even harms the circuit.  
           [0006]    In addition, generally high-tech devices should avoid hitting and bumping. Other than the charger mentioned before, since portable devices are designed for convenient carrying, their structure designs have been strengthened. However, without proper handling, they can still be damaged by improper hitting and bumping. Take the example of PDA (Personal Digital Assistant), due to the continuous innovation of technology, its size gets smaller and smaller while the precision gets higher and higher, but design for device protection still lags behind.  
           [0007]    In conclusion, the shortcomings of the prior art includes:  
           [0008]    1. Lack of support and fixation function;  
           [0009]    2. Unable to provide effective support during the recharging duration to fully utilize the recharge efficiency.  
         SUMMARY OF THE INVENTION  
         [0010]    To improve the shortcomings of prior art, the present invention provides a supporting frame structure that is used to support a portable device and comprises a supporting frame, a lifting frame, a base and hinges coupling together, so the portable device can be securely placed on top of the base and not be damaged by negligence or external forces.  
           [0011]    A supporting frame and a lifting frame are assembled on top of the base and hinges are used to secure the supporting frame and the lifting frame. When the supporting frame rotates upwards and moves hinges, the moving hinges then move the lifting frame to slide along the sliding track groove to a fixed angle and secure the lifting frame and the supporting frame onto the base.  
           [0012]    Accordingly, it is a primary object of the present invention for the portable device to avoid external disturbances when placed on the base to fully utilize the base&#39;s operation efficiency, e.g., the recharging operation.  
           [0013]    It is another object of the present invention to provide ease operation that can be built with a single action to allow a portable device to be securely placed.  
           [0014]    It is a further object of the present invention to provide a supporting frame that is able to maintain the visual coherence of exterior design while not in use and also convenient storage.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0023]    This invention disclosed herein is directed to a supporting frame structure. In the following description, numerous details are set forth in order to provide a thorough understanding of the present invention. It will be appreciated by one skilled in the art that variations of these specific details are possible while still achieving the results of the present invention. In other instance, well-known components are not described in detail in order not to unnecessarily obscure the present invention.  
         [0024]    Please refer to FIG. 2, a schematic structure view of a preferred embodiment in accordance with the invention, which is a supporting frame structure used to support a portable device. The structure shown in FIG. 2 comprises a supporting frame  10  and abase  20 . The supporting frame  10  is connected to the base  20  by the use of hinges and revolving axis. With one single-direction movement, the supporting frame  10  can be lifted upwards to a fixed angle to complete the buildup and placement.  
         [0025]    Please refer to FIG. 3, a schematic structure explosion view of a preferred embodiment in accordance with the invention, which allows a better understanding of the connecting relationship between the hinges and revolving axis of the supporting frame  10  and the base  20 . The supporting frame  10  is a           shape frame and includes a pair of supporting revolving axis  17  at the front ends of its two arms. The supporting revolving axis  17  are placed into the matching supporting revolving axis holes  23  of the base  20  to fasten the supporting frame  10 . The supporting revolving axis  17  further includes a revolving axis tenon  18  that is used to connect and fasten the supporting frame  10  and base  20 . By fastening the supporting revolving axis  17  onto the base  20 , the supporting frame  10  can be lifted upwards by the user.  
         [0026]    As shown in FIG. 3, the center of the supporting frame  10  is connected with a lifting frame  14  and on one end of the lifting frame  14  further includes a sliding pivot  16 . The sliding pivot  16  is placed in a sliding track groove  26  on the base  20  to connect the supporting frame  10  and the lifting frame  14  with the base  20 . Through the use of sliding track groove  26 , the lifting frame  14  props up while the supporting frame  10  being lifted upwards, i.e., the supporting frame  10  is supported by the prop-up lifting frame  14 . And after the sliding pivot  16  moves backwards to the end of the sliding track groove  26 , the supporting frame  10  is supported upwards at a fixed position. The connecting relationship of the supporting frame  10  and the lifting frame  14  will be elaborated in detail in FIG. 4 and FIG. 5.  
         [0027]    Besides of the supporting revolving axis holes  23  and the sliding track groove  26 , the base  20  further includes a supporting frame storage groove  24  and a hinge storage groove  25 , a storage trough  27  and a display unit  28 , as shown in FIG. 3. The supporting frame storage groove  24  provides storage for the supporting frame  10  when it&#39;s not in use. It is able to maintain structure coherence, improve visual aesthetics, and be carried conveniently by allowing the supporting frame  10  to be stored in the supporting frame storage groove  24  during its idle state. In addition, since the connection between the lifting frame  14  and the supporting frame  10  is protruded out from the supporting frame  10 , by the use of the hinge storage groove  25 , the supporting frame  10  does not protrude out from the supporting frame storage groove  24  of the base  20  when it is not in use. The storage trough  27  is for placing user belongings and its size can vary depends on the intended portable object. The present invention is not limited for the use of potable electronic devices, like mobile phone or PDA (Personal Digital Assistant), but also can be used for other electronics communication devices or instruments, or even computer peripherals. The display unit  28  is used to inform user the operation status of the portable device, for example, when the base to be a charger, the display unit  28  is able to inform user the recharging status of the portable device.  
         [0028]    Please refer to FIG. 4, a schematic structure explosion view of the supporting frame  10  and the lifting frame  14  of a preferred embodiment in accordance with the present invention. As stated before, the supporting frame is a           shape structure and includes a supporting revolving axis  17  at each front end of its two arms, while the center of the supporting frame  10  is connected to the lifting frame  14 . The detail descriptions of the supporting revolving axis  17  and the lifting frame  14  have been stated in FIG. 3 and won&#39;t be repeated. The description stated here is only for the connect ion between the supporting frame  10  and the lifting frame  14 . As shown in FIG. 4, there is a hinge  12  at both ends of where the supporting frame  10  and the lifting frame  14  are connected, and the two hinges  12  are placed in the two hinge grooves  19  on the supporting frame  10 . Each hinge  12  further includes a pivot  13  which is matched with a pivot fastening hole  15 . The both pivot fastening holes  15  are mounted on both sides of the front end of the lifting frame  14 , so the lifting frame  14  is placed at the center of the supporting frame  10  through the pivots  13 , while the two hinges  12  become a hinge frame  11  and connect the lifting frame  14  and the supporting frame  10  to allow them to rotate a certain angle.  
         [0029]    The hinges  12  shown in FIG. 4 allow the supporting frame  10  to spring back after being rotated to a certain angle, and different angles produce various strengths and directions of torques in order for the buildup and storage of the supporting frame  10 . The hinge  12  used in the present invention is different from general door hinges. Ordinary hinges can only be used for the purpose of rotation and cannot spring back after being rotated to a certain angle. For example, the hinge used by the notebook screen cannot spring back after being rotated to a certain angle. The hinge used in the present invention is able to provide torque, so after the supporting frame  10  is lifted up to an angle, it only requires one hand to handle the lifting frame  14 , so that the supporting frame  10  springs back immediately and retreats to the base  20 , back to its idle state. And when the supporting frame  10  is lifted, the sliding pivot  16  of the lifting frame  14  can also be secured at the end of the sliding track groove  26 .  
         [0030]    Please refer to FIG. 5A, a first schematic view of a preferred embodiment in use in accordance with the present invention. When the base is not in use, the supporting frame  10  is stored in the supporting frame storage groove  24  of the base  20 , the hinge frame is also stored in the hinge storage groove  25 , and the lifting frame  14  is placed flat in the sliding track groove  26 , which allows to maintain the visual coherence of the structure. FIG. 5B is a second schematic view of a preferred embodiment in use in accordance with the present invention. As shown in FIG. 5B, the base  20  is in its active, state, where the supporting frame  10  is able to rotate upwards through the support of the supporting revolving axis  17 . And the hinge frame  11  moves the lifting frame  14  and the sliding pivot  16  of the lifting frame  14 , with the sliding pivot sliding along the sliding track groove  26  to the end of the sliding track groove  26 , the supporting frame  10  and the lifting frame  14  forms an angle, as shown in FIG. 5C, a third schematic view of a preferred embodiment in use in accordance with the present invention. When the bottom of the lifting frame  14  is secured at the end of the sliding track groove  26 , the supporting frame  10  is lifted upwards and secured at an angle for the user to place a portable object on top of the base  20 .  
         [0031]    The specification stated above uses the rechargeable devices like mobile phone or PDA as examples of a preferred embodiment. In fact, the structure of the present invention can also be used for other electronic communication devices and instruments or computer peripherals, to provide steady support for the electronic devices or computer peripherals. The only differences of the structure being used for various devices are the size and the placement method, and the structure can be used alone or in company with the base to provide steady support.  
         [0032]    In conclusion, the advantages of the present invention may include:  
         [0033]    1. Simple structure and can be easily assembled.  
         [0034]    2. Easy operation, which only needs one single-direction movement to complete the buildup.  
         [0035]    3. Convenient storage, which maintains the visual coherence of external appearance.  
         [0036]    While the present invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be without departing from the spirit and scope of the present invention.
