Abstract

본 발명은 지지대를 필요로 하지 않는 환형 나침반에 관한 것이다.The present invention relates to an annular compass that does not require a support.

종래의 나침반은 지침을 사용하는 것으로 독립된 물품으로 되어 휴대 ·보관상에 문제가 있었다.Conventional compasses have a problem in carrying and storing as an independent article by using a guide.

본 발명의 목적은 손목시계 등에 일체로 부착하여 사용할 수 있는 환형의 나침반을 제공하는 것이다.It is an object of the present invention to provide an annular compass which can be used integrally with a watch or the like.

본 발명의 환형 나침반은 투명한 재질의 내부가 공동으로 된 환형의 케이스(2), 그 속에 동심원적으로 배치되며 영구자석편(6)을 지닌 환형의 방위지시체(5) 및 상기 방위지시체(5)를 케이스(2)의 내부공동의 중심부에 회전자재하게 부유시키도록 케이스(2)의 내부공동에 충전되는 점도가 낮고 윤활성 이 좋은 액체를 포함하여 구성된다.The annular compass of the present invention is an annular case (2) having a hollow inside of a transparent material, concentrically disposed therein, and an annular bearing indicator (5) having a permanent magnet piece (6) and the bearing indicator (5). It is configured to include a liquid having a low viscosity and good lubricity to be filled in the inner cavity of the case (2) so as to rotate freely in the center of the inner cavity of the case (2).

Claims

In an annular compass without support, a permanent magnet piece is arranged concentrically in an annular case (2) of transparent material in which the bearing is indicated on the outer surface and the inside is an annular cavity, and the annular inner cavity of the case (2). A low viscosity and good lubricity to fill the azimuth indicator (5) having the (6), and the azimuth indicator (5) in the inner cavity of the case (2) so as to rotate freely in the center of the inner cavity of the case (2) An annular compass, characterized in that it comprises a liquid (10).

2. The azimuth indicator (5) according to claim 1, characterized in that the azimuth indicator (5) consists of two opposing permanently arranged permanent magnets (6) made of a rare earth metal of Samarium material and an end portion of the permanent magnet piece (6) to form an overall annular shape. Two tube members (7). Annular compass, characterized in that the air is full except the portion occupied by the permanent magnet (6) of the tube member (7).

3. The annular compass according to claim 2, wherein the liquid (10) is made of petroleum having a specific gravity of 0.6-0.8, and the permanent magnet piece (6) is cobalt-based.

4. An annular compass according to claim 3, characterized in that the micro bearing (11) is used as sliding means in place of the liquid filled in the cavity in the case (2).
