DESCRIPTION OF THE PREFERRED EMBODIMENTS
Refer to FIGS. 1 and 2 for an embodiment of the anchor structure for electronic devices of the invention. It mainly includes a first bar 1 and a second bar 2 that are pivotally coupled together through a hinge means 3. Through a fastening means 4 the hinge means 3 can be selectively set to a swivelable condition or a non-swivelable condition, and the first bar 1 and the second bar 2 also can be set to a corresponding swivelable condition or a non-swivelable condition.
Referring to FIG. 3, the first bar 1 and the second bar 2 are respectively a rod. The first bar 1 has a housing space 11 formed in a portion of the interior. The hinge means 3 includes an axle 31 hinged on one end of the first bar 1. The second bar 2 is fastened to the peripheral surface of the axle 31 so that the second bar 2 can be swiveled relative to the first bar 1 through the axle 31. The fastening means 4 includes a handle 41 which has a hinge portion 41a on a bottom end corresponding to the housing space 11 and pivotally coupled with the first bar 1. The hinge portion 41a runs through the first bar 1 and fastens to a cam 42 in the housing space 11. The cam 42 has a protrusive portion 42a on one side formed in a selected surface profile. The housing space 11 has one end leading to where the first bar 1 being coupled with the axle 31. The housing space 11 also holds a slidable brake element 43 and fastens to a spring 44 in a fixed manner on the one end. The spring 44 aims to keep the brake element 43 in contact with the cam 42 tightly so that turning of the cam 42 can selectively make the braking element 43 to slide away from the axle 31 or in a tight contact condition with the axle 31 to make the axle 31 in a swivelable condition or non-swivelable condition.
The axle 31 has a teeth structure on the peripheral surface to form a teeth surface 32. The brake element 4 has an end surface made from rubber corresponding to the axle 31 for pressing thereon. Hence the friction force between the brake element 43 and the teeth surface 32 can be increased.
The pivotal coupling portion of the first bar 1 and the axle 31 also has a damping wheel 33 which has a portion of elements fastened to the first bar 1, while other portion of the elements is fastened to the axle 31 so that when the first bar 1 swivels relative to the axle 31 the damping wheel 33 provides a damping resistance. Hence when the brake element 43 loosens the compression on the axle 31, the damping wheel 33 provides resistance against swiveling of the first bar 1 about axle 31 so that the second bar 2 can be firmly anchored on a selected position, and reduce the relative swiveling between the first bar 1 and the second bar 2 caused by gravity force.
The first bar 1 may have a base 5 on other end to mount the anchor structure onto the surface of a selected object. The second bar 2 may have a holding dock 6 on other end to hold the electronic device so that the whole anchor structure can be mounted onto the surface of the selected object.
Referring to FIGS. 3 and 4, when the handle 41 is moved to a first condition, the cam 42 rams the brake element 43 outwards in contact tightly with the teeth surface 32 of the axle 31 so that the axle 31 is in an anchored condition, and the first bar 1 and the second bar 2 are in the non-swivelable condition relative to each other. When the handle 41 is moved to a second condition, the cam 42 is released from the brake element 43, the brake element 43 is pushed inwards by the spring 44 to escape the teeth surface 32 of the axle 31, hence the first bar 1 and the second bar 2 are in the swivelable condition. But swiveling of the first bar 1 and second bar 2 is resisted by the damping wheel 33 and is proceeded in a slower fashion.
Refer to FIG. 5 for another embodiment of the invention. The base 5 has a top end fastened to a third bar 7. The first bar 1 is pivotally coupled with the top end of the third bar 7 through a second hinge means 3′. The second hinge means 3′ has a second axle 31′ pivotally coupled on one end of the first bar 1. The third bar 7 is fastened to the periphery surface of the second axle 31′ so that the third bar 7 can be swiveled relative to the first bar 1 through the second axle 31′. The handle 41 has a hinge portion 41a on the bottom end running through the first bar 1 and fastened to the cam 42 in the housing space 11. The cam 42 has a first protrusive portion 42a and a second protrusive portion 42b on two opposite sides formed respectively in a selected surface profile. The housing space 11 has one end leading to where the first bar 1 being coupled with the axle 31, and another end leading to where the first bar 1 being coupled with the second axle 31′. The housing space 11 further has a first brake element 43 and a second brake element 43′ slidable on two ends, and a first spring 44 and a second spring 44′ anchoring on the two ends. The first and second springs 44 and 44′ make respectively the brake elements 43 and 43′ in contact tightly with protrusive portions 42a and 42b of the cam 42 so that rotation of the cam 42 can selectively make the brake elements 43 and 43′ to escape the axles 31 and 31′, or slide to ram the axles 31 and 31′ tightly to allow the axles 31 and 31′ in a swivelable or non-swivelable condition.
When the handle 41 is moved to the first condition, the protrusive portions 42a and 42b of the cam 42 ram the brake elements 43 and 43′ outwards in contact tightly with the teeth surface 32 of the axle 31 so that the axle 31 is in an anchored condition, and the first bar 1 and the second bar 2 are in a non-swivelable condition relative to each other. Meanwhile the second brake element 43′ is in contact tightly with the second teeth surface 32′ to anchor the second axle 31′. The first bar 1 and the third bar 7 can also be selectively set to a non-swivelable condition. When the handle 41 is moved to the second condition, the protrusive portions 42a and 42a of the cam 42 are released from the brake elements 43 and 43′, and the brake elements 43 and 43′ are pushed inwards respectively by the springs 44 and 44′ inwards so that the first brake element 43 escapes the teeth surfaces 32 of the axle 31, and the first bar 1 and the second bar 2 can be selectively set in a swivelable condition relative to each other. Meanwhile the second brake element 43′ is moved away from the second teeth surface 32′ of the second axle 31′, and the first bar 1 and the third bar 7 can be selectively set in a swivelable condition relative to each other.
