Retractable fixture for portable visual electronic products

Abstract

This new and novel retractable fixture for portable visual electronic products is composed of a fixing clip, a supporting rod and a fixing base. The supporting rod is hinged to the fixing clip at one end and connected to the fixing base at the other. The fixing base is connected to the portable visual electronic product and the supporting rod is adjustable. This fixture quickly and easily adjusts the visual direction, angle and distance of portable visual electronic products and applies to common vehicles like various automobiles.

1 . A retractable fixture assembly for portable visual electronic products including an adjustable fixing clip means, an extendable supporting rod assembly and a fixing base assembly, means for hingedly connecting the fixing clip means to one end of the supporting rod assembly and means for connecting the fixing base assembly to the other end of the supporting rod assembly.  
   
   
       2 . The retractable fixture assembly as set forth in  claim 1  in which the supporting rod assembly comprises relatively movable internal and external sleeves and a spiral fixing block, the external sleeve has external threads and adjacent thereto includes a protruding pressure block, the fixing block includes internal threads whereby it is connected to the external sleeve and after the sleeves are relatively moved to a preselected position the spiral fixing block is adjusted to engage the pressure block to act against the internal sleeve to secure the sleeves and thus, the supporting rod assembly in the desired position.  
   
   
       3 . The retractable fixture assembly as set forth in  claim 1  in which the supporting rod assembly consists of internal and external sleeves and a spiral fixing block threaded on the external sleeve said external sleeve is threaded on its outside and defines notches at its end to permit inward bending thereof, said fixing block defines a conical opening whereby when the block is moved on said external sleeve the external sleeve is pressed inwardly against the internal sleeve to secure the internal and external sleeves relative to each other.  
   
   
       4 . The retractable fixture assembly as set forth in  claim 1  in which the fixing clip means comprises two clamping rods that are hingedly connected to the supporting rod assembly at one end thereof and means are provided at the other ends of the clamping rods to affix the clamping rods to a support member to secure the portable electronic product to be secured to the fixture assembly in a fixed position relative to the support member.  
   
   
       5 . The retractable fixture assembly as set forth in  claim 4  in which the means for hinging the fixing clip means to the supporting rod assembly include a first connecting block means that defines spherical concaves arranged in a circle at both sides thereof, and the clamping rods include a second connecting block means located on both sides of the first connecting block means including spring means therein, and disposed between the first and each of the second connecting block means are small steel balls, said springs act to press the small steel balls into said spherical concaves to circumferentially connect said blocks together, and means are provided to secure said blocks together.  
   
   
       6 . The retractable fixture assembly as set forth in  claim 5  in which said springs and said small steel balls are identical in number and the springs are regularly distributed between said first and second connecting blocks and there are included spring pressers disposed inside each of the second connecting blocks and the pressers define regularly distributed round holes for holding the springs.  
   
   
       7 . A retractable fixture assembly as set forth in  claim 1  in which the supporting rod assembly comprises relatively movable internal and external sleeves, and the means for connecting the fixing base assembly to the other end of the supporting rod assembly includes a connecting block assembly and means for connecting the internal sleeve to said connecting block assembly.  
   
   
       8 . A retractable fixture assembly as set forth in  claim 7  in which the means for connecting the internal sleeve to the connecting block assembly includes holes defined by said connecting block assembly, clamping pieces disposed adjacent said holes and means for securing said clamping pieces to said internal sleeve.  
   
   
       9 . A retractable fixture assembly as set forth in  claim 8  in which the connecting block assembly defines spherical concave surfaces on an end portion of the connecting block assembly and the fixing base assembly defines a convex contacting surface of steel balls through which the fixing base is embedded into the spherical concaves of the connecting block to circumferentially secure the fixing base and the connecting block, the end surface of the connecting block and the center of the convex contact surface defines holes, and fastening means including studs extending through said holes for axially securing the fixing base to the connecting block.  
   
   
       10 . A retractable fixture assembly as set forth in  claim 9  in which the convex contact surface of steel balls is formed by presser means pressing the steel balls against one side of the fixing base partially out of the holes to engage the concave surfaces defined by the connecting block assembly.  
   
   
       11 . A retractable fixture assembly as set forth in  claim 10  in which the fixing base includes a base body assembly adapted to be connected to a movable clamping piece connected to the portable electronic product to which the fixture assembly is to be connected, the base body assembly including a clamping flange and an elastic stopper located at one end of the clamping flange whereby the movable clamping piece and the base body are connected through the clamping flange and a clamping block located at the back of the movable clamping piece.
