Adjustable pivot joint
First Claim
Patent Images
1. A pivot joint comprising:
- a first rotation arm and a second rotation arm, the first rotation arm coupled to an engagement piece having at least one portion with an angled perimeter, and the second rotation arm having a locking portion also having an angled perimeter, wherein the angled perimeters of the at least one portion of the engagement piece and the locking portion allow the locking portion to receive the engagement piece to provide a locking mechanism for the pivot joint;
a pivot piece about which the first rotation arm and the second rotation arm are rotatable, and a spring mechanism positioned around the pivot piece and between the first rotation arm and the second rotation arm;
a release mechanism having a series of pins, the second rotation arm having a series of holes through which the series of pins are positioned, wherein the series of pins extend through the series of holes to move the engagement piece against the spring mechanism and out of the locking portion when the release mechanism is activated to allow at least one of the first rotation arm and the second rotation arms to move relative to the other.

Abstract
An adjustable pivot joint includes rotation arms which, when locked, prevent pivoting about an axis. A release mechanism is used to unlock the rotation arms to allow pivoting about the axis for adjustment of the pivot joint. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

15. A pivot joint comprising:
-
a rotation mechanism having a first rotation arm coupled to an engagement piece and a locking portion recessed within a second rotation arm, the engagement piece having a plurality of teeth, and the locking portion having a plurality of grooves, such that when the engagement piece is positioned within the locking portion and the plurality of teeth and the plurality of grooves are aligned together, the rotation mechanism lockably engages the first rotation arm and the second rotation arm; and
a release mechanism configured to disengage the first rotation arm and the second rotation arm by removing the plurality of teeth from the plurality of grooves when a spring mechanism positioned between the first rotation arm and the second rotation arm is compressed. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of pivoting a joint apparatus, comprising:
-
providing a first rotation arm and a second rotation arm, the first rotation arm coupled to an engagement piece having at least one portion with a sloped perimeter, and the second rotation arm having a locking portion also having a sloped perimeter capable of receiving the at least one portion of the engagement piece;
releasing the engagement piece from the locking portion by moving the first rotation arm to apply pressure against a spring mechanism;
rotating at least one of the first and second rotation arms around a pivot piece; and
locking the first and second rotation arms in a desired position by releasing pressure on the spring mechanism and engaging the engagement piece and the locking portion to prevent the first and second rotation arms from moving relative to each other. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
