Abstract
A tool capable of creating and measuring circles and circular profiles of any size without the need for a pivoting center arm. Circle size can be selectively adjusted and held, and both the inside and outside of tool creates and measures circles of a near infinite number of size. The tool contains marking rules such as radius, diameter, arc length, circumference, sector area, area of a circle for any size circle, etc., obviating the need for calculating the same, and any or a combination of unit measure systems can be employed.
Claims21
A device for creating curved shapes having a flexible ring-like body comprised of at least one part with at least a first arm, second arm, and transition section,
- a. wherein said transition section is located between said first and second arms, and
- b. wherein said first and second arms are slidably secured to each other by means of a mechanical fastener, and
- c. wherein one of the said arms is stacked on the other such that at least the inner or outer edges of said arms follow the same curvature when viewed from either the top of or bottom view of the device when said arms are slidably engaged, each of said arms having an inner circumferential edge and the inner circumferential edges of said arms are overlapping and coincident, and wherein a cross-sectional profiles of said first arm, second arm, and transition section comprise cut-out material sections patterned around a sweep profile or shape of the device for improving the bendability of the device.
A device for creating curved shapes having a flexible ring-like body and comprised of at least two parts,
- a. wherein said first part comprises a first arm and a transitions section and said second part comprises at least a second arm
- b. wherein said first and second parts comprise mechanical fastening features capable of securing said first and second part to each other such that said transition section is preferrably located between said first and second arms, and
- c. wherein said first and second arms are slidably secured to each other by means of a mechanical fastener, and
- d. wherein one of the said arms is stacked on the other such that at least the inner or outer edges of said arms follow the same curvature when viewed from either the top or bottom view of the device when said arms are slidably engaged, each of said arms having an inner circumferential edge and the inner circumferential edges of said arms are overlapping and coincident, and wherein a cross-sectional profiles of said first arm, second arm, and transition section comprise cut-out material sections patterned around a sweep profile or shape of the device for improving the bendability of the device.
A device for creating curved shapes having a flexible ring-like body and comprised of at least three parts,
- a. wherein a first part comprises a first arm, a second part comprises a second arm, and a third part comprises a transitions, and
- b. wherein said first, second, and third parts comprise mechanical fastening features capable of securing said first, second, and third parts to each other such that said transition section is preferably located between said first and second arms, and
- c. wherein said first and second arms are slidably secured to each other by means of a mechanical fastener, and
- d. wherein one of the said arms is stacked on the other such that at least the inner or outer edges of said arms follow the same curvature when viewed from either the top or bottom view of the device when said arms are slidably engaged, each of said arms having an inner circumferential edge and the inner circumferential edges of said arms are overlapping and coincident, and wherein a cross-sectional profiles of said first arm, second arm, and transition section comprise cut-out material sections patterned around a sweep profile or shape of the device for improving the bendability of the device.
