Abstract

An adjustable device holder includes a holder base including a bottom panel, a cover panel covering the bottom panel, two parallel sliding grooves located on the bottom panel and a shaft column located at the bottom panel between the sliding grooves, and an adjustment module including two adjustment plates slidably coupled to the sliding grooves and having a respective integrated tooth rack, two clamping members respectively pivotally connected to the adjustment plates for holding a mobile electronic device therebetween and a rotating wheel coupled to the shaft column of the holder base and having an integrated external ring gear meshed between the tooth racks of the adjustment plates.

Claims

1. An adjustable device holder, comprising:

a holder base comprising a bottom panel, a cover panel covering said bottom panel, an accommodation chamber defined between said bottom panel and said cover panel, two access holes bilaterally defined between said bottom panel and said cover panel and disposed in communication between said accommodation chamber and the atmosphere and a control member inserted through said cover panel, a shaft column located at a center of an inner wall thereof, a mounting structure located at a center thereof, an operating hole cut through opposing top and bottom walls thereof and disposed adjacent to one lateral side of said mounting structure, a bottom release member, said bottom release member comprising an operating rod inserted through said operating hole of said cover panel and a press portion extended from a front side thereof and suspending in a bottom side relative to said mounting structure, a positioning member, said positioning member comprising a bearing portion located at a front end thereof for stopping against said press portion of said bottom release member and a pressure surface and an engagement portion respectively located at opposing top and bottom sides of an opposing rear end thereof, said control member comprising a push rod extended from a bottom side thereof and stopped against said pressure surface of said positioning member and a knob located at a top side thereof and suspending outside said cover panel; and

an adjustment module adjustably mounted at said holder base for holding a loaded mobile electronic device, said adjustment module comprising two adjustment plates, two pivot joints, two clamping members respectively pivotally connected to said adjustment plates by said pivot joints, and a rotating wheel rotatably coupled to said shaft column of said bottom panel, each said adjustment plate comprising two parallel sliding rails respectively slidably coupled to sliding grooves of said bottom panel, an engagement portion disposed between said two parallel sliding rails and facing toward one of said bottom release member and said positioning member of said cover panel, an extension arm forwardly extended from a front end thereof, a tooth rack formed integral with and extending along an inner side of said extension arm, each said clamping member defining therein a clamping hole for securing a mobile electronic device, said rotating wheel comprising a center axle hole rotatably coupled to said shaft column of said bottom panel and an external ring gear formed integral with a periphery thereof and meshed with the tooth racks of said adjustment plates.

2. The adjustable device holder as claimed in claim 1, wherein said bottom panel further comprises a plurality of stop blocks spaced around a periphery of said shaft column;

said rotating wheel of said adjustment module further comprises an inside annular flange formed in one end of the center axle hole thereof for stopping against said stop blocks of said bottom panel.

3. The adjustable device holder as claimed in claim 1, wherein said holder base further comprises a rotating hole formed in said mounting structure of said cover panel, an internal gear formed integral with a part of said mounting structure within said rotating hole, and a rotating member rotatably capped on said rotating hole, said rotating member comprising a plurality of equiangularly spaced and downwardly extending retaining strips, a locating block located on an outer side of each said retaining strip and meshed with said internal gear.

4. The adjustable device holder as claimed in claim 1, wherein said cover panel of said holder base further comprises a plurality of engagement blocks located on a bottom wall thereof at two opposite sides of said operating hole in a parallel manner;

said bottom release member further comprises a plurality of sliding slots spaced around said operating rod and respectively slidably coupled to said engagement blocks of said cover panel.

5. The adjustable device holder as claimed in claim 1, wherein said cover panel of said holder base further comprises two locating plates extended from the bottom wall thereof adjacent to an opposite lateral side of said mounting structure, each said locating plate defining therein a pivot hole, said positioning member comprising two pivot rods symmetrically disposed at two opposite lateral sides thereof and respectively pivotally coupled to the pivot holes of said two locating plates.

6. The adjustable device holder as claimed in claim 1, wherein each said adjustment plate of said adjustment module further comprises a longitudinal rib located on the extension arm thereof, and a sliding groove disposed in parallel to said longitudinal rib, the longitudinal rib of one said adjustment plate being coupled to the sliding groove of the other said adjustment plate.

7. The adjustable device holder as claimed in claim 1, wherein each said pivot joint comprises a pivot hole located on one respective said adjustment plate, a tubular pivot pin located on one respective said clamping member, and a rivet fastened to said tubular pivot pin to pivotally secure said tubular pivot pin to the pivot hole of the respective said adjustment plate.

8. The adjustable device holder as claimed in claim 1, wherein each said clamping member of said adjustment module comprises a cushion pad fixedly bonded thereto around the clamping hole thereof.
