Abstract

PURPOSE: A multi compass is provided to apply various writing articles, and to draw a circle or an arc in various materials. CONSTITUTION: A multi compass comprises a knurling (111), and a circular spring steel (112). The knurling is arranged in a top of a center of the spring steel. The spring steel comprises a handle unit (110) including an open interval; a center supporting unit (120) connected to one end of the open interval; a pen holder (131), a pen holder supporting unit (132), and a connecting unit (133), and is connected to the other end of the open interval. The pen holder comprises a pair of pen holding members. A pair of the pen holding members and the pen holder supporting unit is combined through the connecting unit. A rotation of the pen holder and a distance between pen holding members are controlled when the connecting unit is loosely combined. A pen holding unit (130) which prevents a control of the distance and the rotation is included, when the connecting unit is tightly combined.

1 to 3, the multi compass 100 includes a handle part 110, a center support part 120, a pen holding part 130, and a radius adjusting part 140. In one embodiment, the multi compass 100 may further include a ruler 150 and a ruler fixing bolt 160.

The handle portion 110 is composed of a circumferential shaped nuling 111 and a circular spring steel 112.

The knurling 111 may be disposed on the top of the center of the spring steel 112. This is to allow the user to easily draw a circle or an arc by rotating the multi-compass 100 while holding the circumferential knurling 111. In one embodiment, the knurling 111 may correspond to about 20 mm to 40 mm in the longitudinal direction.

The spring steel 112 may form an opening in the opposite direction to which the knurling 111 is coupled. One end between the openings of the spring steel 112 may be coupled to the central support 130, and the other end may be coupled to the pen holding unit 140.

The radius adjusting unit 140 may adjust the distance between the center supporting unit 120 and the pen holding unit 130 by connecting the spring steel 112, the center supporting unit 120, and the pen holding unit 130 together. In one embodiment, the radius adjusting unit 140 may be composed of a bolt and a nut. In one embodiment, the ruler 150 may be attached to one end of the radius adjusting unit 140, and may be fixed by the ruler fixing bolt 160.

The central support 120 may be coupled to one end between the openings of the spring steel 112, and the other end may become increasingly sharper away from the engagement portion. This may allow the center point to be accurately positioned and fixed when drawing a circle or an arc with the multi-compass 100.

The pen holding part 130 includes a pen holder 131, a pen holder support 132, and a fastening part 133.

One end of the penholder support 132 may be coupled to the other end between the openings of the spring steel 112. The pen holder 131 may be composed of a pair of pen holding members, and each pen holding member may have a semi-cylindrical shape. One end of each pen holding member may be coupled to the pen holder support 132 through a fastening portion 133. In one embodiment, the semi-cylindrical shape of the pair of pen-holding members may face and insert and fix various writing instruments therebetween. The fastening part 133 may be composed of a bolt and a nut, and the bolt may be implemented with a butterfly bolt to facilitate loosening and tightening by hand.

In one embodiment, when the fastening part 133 is loosely coupled, the rotation of the pen holder 131 and the distance between the pair of pen holding members can be adjusted, and when tightly coupled, the rotation of the pen holder 131 and the pair of pen holding are performed. Control of distance between members can be prevented. In one embodiment, the fastening portion 133 may adjust the degree of looseness or tightness by loosening, tightening between the bolt and the nut.

It is a figure explaining the penholder rotation of a multi compass.

Referring to FIG. 4, the multi-compass 100 can adjust the penholder 131 fastening force by loosening and tightening the bolt and nut of the fastening part 133, and pairing with the rotation of the pen holder 131 when the fastening force is weak. It is possible to adjust the distance between the pen holding member of the.

As a result, the multi-compass 100 may be used to draw circles or arcs of various sizes through the rotation of the pen holder 131.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims It can be understood that
