Abstract
Abstract The invention relates to a universally movable suspension member for a direction indicating display system, especially for a gyro system (2), in which a bellows unit (1) is provided between a revolving disk (3) and the gyro system (2). The suspension member is designed as a double-bellows unit including two oppositely folded bellows (5, 6) so that, while a reliable and accurate indication is obtained, the volume of construction is decreased and the manufacturing costs are reduced.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
A universally movable suspension member for direction-indicating display systems, especially for a gyro system (2), in which the suspension member is disposed between a revolving disk (3) and the gyro system (2) to suspend the gyro system from the disk for pendulum type motion about a pivot point (9) spaced beneath said disk, and wherein the suspension member has the form of a concentric double-bellows unit (1) having a flexible bellows section (7) comprising a plurality of axially spaced pairs of registering, oppositely directed folds (5,6), wherein the space defined between said pairs of oppositely directed folds is filled with a damping liquid, and wherein a supporting ring (8) is dipsosed in the space between each pair of said registering folds.
Claim 2
Dependent Claim
121 words
A universally movable suspension member for direction-indicating display systems, especially for a gyro system (2), in which the suspension member is disposed between a revolving disk (3) and the gyro system (2) to suspend the gyro system from the disk for pendulum type motion about a pivot point (9) spaced beneath said disk, and wherein the suspension member has the form of a concentric double-bellows unit (1) having a flexible bellows section (7) comprising a plurality of axially spaced pairs of registering, oppositely directed folds (5,6), wherein the space defined between said pairs of oppositely directed folds is filled with a damping liquid, and wherein a supporting ring (8) is dipsosed in the space between each pair of said registering folds.
Claim 3
Dependent Claim
22 words
A suspension member as claimed in claim 1, characterized in that the supporting rings (8) include throttling openings communicating with said liquid.
Claim 4
Dependent Claim
38 words
A suspension member as claimed in claim 1, characterized in that the flexible section (7) of the bellows unit (1) is made of a material selected from the group consisting of rubber, resilient metal, polytetrafluoroethylene and elastomeric plastics.
Claim 5
Dependent Claim
31 words
A suspension member as claimed in claim 1, characterized in that each supporting ring is made of a material selected from the group consisting of brass, aluminum, plastics and plastics-reinforced fabric.
Claim 6
Dependent Claim
29 words
A suspension member as claimed in claim 1, characterized in that the liquid in the double bellows unit is selected from the group consisting of glycerin and silicone fluid.
Claim 7
Dependent Claim
50 words
A suspension member as claimed in claim 1, wherein said flexible bellows section (7) is annular in configuration, and said gyro system (2) is enclosed in a housing (15) which is secured intermediate its ends in the bottom of said double-bellows unit (1) coaxially of said flexible bellows section (7).
Claim 8
Dependent Claim
30 words
A suspension member as claimed in claim 6, wherein the center of gravity (5) of said gyro system (2) registers approximately with the bottom of said double bellows unit (1).
