摘要:
A compass (1) with safety pivot is disclosed for drawing arcs or complete circles on a surface without perforating it and in an absolutely safe manner for young users. The safety pivot of said compass has a rounded end at the end of a pin (8) housed in the body (9). Said rounded end is partially or fully covered by a non-slip finish (7') designed to be in contact with said drawing surface to define the centre of the arc or circle to be drawn. Application to drawing instruments rotating about a point.

A multi-purpose hand tool has a first member having a first portion and a second portion. A second portion member is slidably and pivotally coupled to the second portion of the first member. A coupling assembly pivotally couples the second member to the second portion of the first member and allows the second portion between a first position proximate a first end of the second portion in which the multi-purpose hand tool can be used to obtain a measurement for a first marking or scribing operation, and a second position proximate a second end of the second portion opposite the first end thereof in which the multi-purpose hand tool can be used to obtain a measurement for a second marking or scribing operation different from the first marking or scribing operation, thereby providing a multi-purpose hand tool reconfigurable for a plurality of purposes.

The present invention is directed to a device (10) for describing arcs. The device (10) includes a pair of legs (12, 14) connected at a pivot joint (16). A shoe (20) is disposed at the end of one leg (12, 14) to support the device (10) and maintain the center point of the arc while the device (10) is used. An instrument (32) is attached to the other leg so arcs can be formed as the device (10) is rotated about the shoe (20). A rack (56) and wheel (64) are also connected to the legs (12, 14) to adjust the radius of the arc.

A multi-purpose hand tool has a first member having a first portion and a second portion, and second member that is slidably and pivotally coupled to the second portion of the first member. A coupling assembly pivotally couples the second member to the second portion of the first member and allows the second member to slide on and pivot relative to the second portion between a first position proximate a first end of the second portion, and a second portion, and a second position proximate a second end of the second portion opposite the first end thereof in wich the multi-purpose hand tool can be used to obtain a first and second measurement for a first and a second marking or scribing operation, thereby providing a multi-purpose hand tool reconfigurable for a plurality of purposes.
