Abstract
A multi-purpose clamp for clamping an attachment to a support structure. This clamp consists of a first rigid panel with two edges, a second rigid panel hingedly attached to the first edge of the first rigid panel, a third rigid panel hingedly attached to the second edge of the first rigid panel, a threaded sleeve and rod for changing the angular orientation of the second rigid panel with respect to the third rigid panel and opposing grips located on the faces of both second and third rigid panels.
Claims15
A multi-purpose clamp for clamping an attachment to a support structure, said clamp comprising:
- (a) a first rigid panel having first and second edges, said edges being parallel and spaced apart, and a face and backside;
- (b) a second rigid panel hingedly attached to the first edge of said first rigid panel and having a face;
- (c) a third rigid panel hingedly attached to the second edge of said first rigid panel and having a face;
- (d) an adjusting means for changing and holding the angular orientation of said second rigid panel with respect to said third rigid panel from a first position wherein the sum of the opposing angles between said second rigid panel and said first rigid panel, and said third rigid panel and said first rigid panel is substantially greater than 180.degree., to a second position wherein said sum of the opposing angles is substantially less than 180.degree.;
- and
- (e) opposing grips attached to the said faces of said second and third rigid panels.
A multi-purpose clamp for clamping an attachment to a support structure, said clamp comprising:
- a first rigid panel having first and second edges and a face and backside;
- second rigid panel hingedly attached to the first edge of said first rigid panel and having a face;
- a third rigid panel hingedly attached to the second edge of said first rigid panel and having a face;
- an adjusting means for changing and holding the angular orientation of said second rigid panel with respect to said third rigid panel from a first position wherein the sum of the opposing angles between said second rigid panel and said first rigid panel, and said third rigid panel and said first rigid panel is substantially greater than 180.degree., to a second position wherein said sum of the opposing angles is substantially less than 180.degree.;
- opposing grips attached to the said faces of said second and third rigid panels;
- said adjustig means includes a threaded sleeve hingedly affixed to said third rigid panel and engaging a threaded rod pivotally attached to said second rigid panel;
- and
- a stop means by which said second rigid panel can move pivotally around a point on the length of said threaded rod but said rod is allowed to pivotally turn around said point.
A multi-purpose clamp for clamping an attachment to a support structure, said clamp comprising:
- (a) a first rigid panel having first and second edges, a face and a backside;
- (b) a second rigid panel hingedly attached to the first edge of said first rigid panel and having a face;
- (c) a third rigid panel hingedly attached to the second edge of said first rigid panel and having a face;
- (d) an adjusting means for changing and holding the angular orientation of said second rigid panel with respect to said third rigid panel from a first position wherein the sum of the opposing angles between said second rigid panel and said first rigid panel, and said third rigid panel and said first rigid panel is substantially greater than 180.degree., to a second position wherein said sum of the opposing angles is substantially less than 180.degree. including a threaded sleeve hingedly affixed to said third rigid panel and engaging a threaded rod pivotally attached to said second rigid panel;
- (e) opposing grips attached to said faces of said second and third rigid panels;
- (f) stops attached to said face of said first rigid panel and extending above said threaded rod and said threaded sleeve;
- and
- (g) a turntable means to orient an attachment to a desired position, said turntable means including a locking means to secure said chosen orientation of said attachment.
