    摘要： A safety compass comprising first and second leg members. The leg members have a pivot opening and an arcuate slot formed in an upper portion thereof. The upper end portion of the leg members are pivotally attached together by a handle member having a pair of spaced apart side leaves that receive the upper end portions of the leg members therebetween. The leaves have horizontally aligned pivot openings and substantial vertical slots formed therein. A pivot pin member extends through the pivot openings formed in the leaves and the leg members. A guide pin member extends into and moves within the slots formed in the leg members and the leaves. A unique means is provided to retain a drawing implement. All of the component parts are preferably fabricated from a plastic material.

    摘要： A drafting or measuring instrument, such as a caliper, divider or compass, has legs pivotally connected at one end and carries working elements at the opposite ends which may be moved between closed and opened positions. A thin case for releasably holding the instrument has an opening with an inner side wall conforming generally to the outer edge of the instrument so that the instrument may be placed in the opening. Formed on the respective opening side wall and the instrument edge are cooperating projections and grooves. The instrument may be manually positioned in the opening with the attaching projections being engaged by the retaining grooves so that the instrument is releasably held in the case until relative pressure is exerted between the instrument and the case to remove the instrument. An aperture may be defined at one end of the opening to receive the working elements of the instrument.

    摘要： A protective member is provided for a compass device including two pivotably connected legs wherein one leg has a distal end including a projecting pin. This end also includes matching elongate slots in opposed surfaces and matching spaced grooves formed in these opposed surfaces at an upper distal portion. The member includes spaced side wall joined by an orthogonal wall. The side walls include internal shoulders at one end and internal, oppositely projecting lugs. The lugs are received in the slots in the one leg to able movement of the member between one end of the slots wherein the member is maintained in an inoperative position, and a second end wherein the member is disposed in an intermediate position. The member is pivotable about the lugs in to an operative position wherein the pin is shielded by the member.

    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.
