Holder and support apparatus

Abstract

A holder and support apparatus is provided for clamping portable devices of different sizes, including a support platform, at least two position adjustment sets, and at least two clamping sets. The support platform is for the electronic device to place on. The platform includes at least two guiding tracks, with each position adjustment set located at a guiding track for sliding and rotating the guiding track to adjust position and angle. Each clamping set is installed on position adjustment set. Through sliding and rotating position adjustment set on guiding track to change the position of clamping elements, the clamping size formed by a plurality of clamping elements can be changed to clamp on devices of different sizes.

What is claimed is: 
     
         1 . A hold and support apparatus, applicable to clamping on portable electronic devices of different sizes, said apparatus comprising:
 a support platform, for placing said portable electronic device, having at least two guiding tracks distributed on said support platform;   at least two position adjustment sets, with each said position adjustment set installed at each said guiding track, said position adjustment set further comprising an arm and a lock element, said arm having a first end and a second end, with said first end engaged to said guiding track and able to slide and rotate on said guiding track, said locking element for fastening said first end of said arm to said guiding track; and   at least two clamping sets, with each said clamping set installed to said second end of said arm, said clamping set further comprising a fixing base and a clamping element installed on said fixing base, said fixing base coupled to said arm and able to rotate around said arm, said clamping elements being for clamping on side wall of said portable electronic device.   
     
     
         2 . The apparatus as claimed in  claim 1 , wherein said support platform comprises a convex carrying base at center area of said support platform. 
     
     
         3 . The apparatus as claimed in  claim 2 , wherein four said guiding tracks are included, and said four guiding tracks are originating from said carrying base and extending outwards toward four corners of said support platform. 
     
     
         4 . The apparatus as claimed in  claim 3 , wherein said guiding tracks have an arc-shaped trajectory. 
     
     
         5 . The apparatus as claimed in  claim 1 , wherein said clamping element is L-shaped, further comprises a vertical plate and a lateral plate, for assembly, said lateral plate is hidden inside said fixing base, said fixing base has an inside space matching the shape of said lateral plate so that said lateral plate can move laterally without being disengaged from said fixing base. 
     
     
         6 . The apparatus as claimed in  claim 5 , wherein said fixing base further comprises a spring inside, with both ends of said spring attached to said lateral plate and a protruding column inside said fixing base, said spring provides a force to press said vertical plate against said fixing base without external force applied. 
     
     
         7 . The apparatus as claimed in  claim 1 , wherein each said guiding track further comprises a guiding trench penetrating said support platform, concave positioning track neighboring on both sides of said guiding trench and against inner wall of said support platform, and tooth rack formed on bottom surface of said positioning track. 
     
     
         8 . The apparatus as claimed in  claim 7 , wherein said lock element further comprises an axial element, a brake element and a wrench element, said first end of said arm has an axial hole and a round slide block, for assembly, said round slide block of said arm is placed inside said positioning track, and said axial element passes, from top to bottom, said axial hole, said guiding trench, and said brake element, said wrench element is coupled to bottom end of said axial element. 
     
     
         9 . The apparatus as claimed in  claim 8 , wherein said brake element is not round, with terminating surface having teeth corresponding to said tooth rack of said guiding track. 
     
     
         10 . The apparatus as claimed in  claim 1 , wherein said support platform comprises three guiding tracks, and the number of said position adjustment sets and said clamping sets are also three; in this manner, said guiding tracks are distributed in area surrounding the center part of said carrying base in an isometric manner, i.e., equal angles among each pair of said guiding tracks.
