Hands-free device capable of adjusting an angle of its mounting seat in any direction and positioning same
View Patent ↗A hands-free device capable of adjusting an angle thereof toward any direction and positioning same includes a suction cup including a central, threaded bolt; a swivel mount rotatably mounted on the suction cup; a first turning assembly rotatably mounted on the swivel mount; an arm having one end pivotably formed with the first turning assembly; a second turning assembly including a pivot formed at one end of the arm and adapted to pivot about the first turning assembly; and a mounting seat fixedly formed at the other end of the arm, the mounting seat including a rotatable seat member projected therefrom for securely engaging with a portable electronic device.
1. A hands-free device capable of adjusting an angle thereof toward any desired direction and positioning the same comprising:
a suction cup ( 1 ) including a central, threaded bolt ( 12 );
a swivel mount ( 2 ) rotatably mounted on the suction cup ( 1 );
a first turning assembly ( 3 ) rotatably mounted on the swivel mount ( 2 );
an arm ( 4 ) having one end pivotably formed with the first turning assembly ( 3 );
a second turning assembly ( 5 ) including a pivot ( 51 ) formed at one end of the arm ( 4 ) and adapted to pivot about the first turning assembly ( 3 ); and
a mounting seat ( 6 ) fixedly formed at the other end of the arm ( 4 ), the mounting seat ( 6 ) including a rotatable seat member ( 66 ) projected therefrom for securely engaging with a portable electronic device,
wherein the swivel mount ( 2 ) comprises:
a base ( 21 ) including a central hole ( 24 );
a central main gear ( 22 ) provided in the hole ( 24 ) and put on the bolt ( 12 );
a plurality of peripheral auxiliary gears ( 23 ) adapted to engage with the main gear ( 22 ); and
a ring ( 20 ) including inner teeth ( 28 ) engaged with the auxiliary gears ( 23 ) such that turning the ring ( 20 ) will cause the main gear ( 22 ) to turn on the bolt ( 12 ) via a gear transmission of the auxiliary gears ( 23 ) for pressing both the base ( 21 ) and the suction cup ( 1 ) to take air between the suction cup ( 1 ) and an attached planar surface away.
2. The hands-free device of claim 1 , wherein the swivel mount ( 2 ) further comprises:
a plurality of first stubs ( 25 ) provided around the hole ( 24 ), and a plurality of second stubs ( 26 ) having inner threads alternately provided with the first stubs ( 25 ).
3. The hands-free device of claim 1 , wherein the main gear ( 22 ) comprises a central threaded channel ( 222 ) secured to the bolt ( 12 ).
4. The hands-free device of claim 2 , wherein the first turning assembly ( 3 ) comprises:
a lower disc ( 31 ) threadedly secured to the second stubs ( 26 ) and including a central, hollow cylinder ( 312 ) and a plurality of first engagement elements ( 311 ) provided around the cylinder ( 312 );
an upper disc ( 32 ) including a central bottom hole ( 321 ), a spring biased pin ( 91 ) inserted through the cylinder ( 312 ) into the hole ( 321 ) for rotatably, slidably putting the upper disc ( 32 ) on the cylinder ( 312 ), a plurality of second engagement elements ( 322 ) provided around the hole ( 321 ) and engaged with the first engagement elements ( 311 ), and two upper risers ( 323 ); and
a cover ( 33 ) secured to the upper disc ( 32 ) and including a cut ( 331 ) with the pivot ( 51 ) formed therein such that lifting the cover ( 33 ) will resiliently disengage the second engagement elements ( 322 ) with the first engagement elements ( 311 ) for enable the cover ( 33 ) to turn about the swivel mount ( 2 ), and lowering the cover ( 33 ) will lockingly engage the second engagement elements ( 322 ) with the first engagement elements ( 311 ).
5. The hands-free device of claim 4 , wherein the first engagement elements ( 311 ) are recesses and the second engagement elements ( 322 ) are projections.
6. The hands-free device of claim 4 , wherein the pivot ( 51 ) comprises a plurality of cavities ( 511 ) arranged as an arc on either side of the cut ( 331 ), and two grooves ( 512 ) formed on both sides of the cut ( 331 ), and the second turning assembly ( 5 ) further comprises:
a bifurcation ( 52 ) including two circular boards ( 521 ) each including a plurality of through holes ( 522 ) arranged as an arc and aligned with the cavities ( 511 ), and two shafts ( 523 ) rotatably provided in the grooves ( 512 ) and rested upon the risers ( 323 );
two mated cup-shaped members ( 53 ) each including a plurality of pegs ( 531 ) provided around its periphery and inserted through the through holes ( 522 ) into the cavities ( 511 ) for releasably securing the bifurcation ( 52 ) to the cover ( 33 ); and
a resilient member ( 54 ) anchored between cup portions of the cup-shaped members ( 53 ) such that pivoting the arm ( 4 ) about the cover ( 33 ) will cause the pegs ( 531 ) to clear the cavities ( 511 ) by compressing the resilient member ( 54 ), and stopping the pivoting will cause the pegs ( 531 ) to enter the cavities ( 511 ) for positioning.
