Abstract

Abstract A device at a multi-way lever, so-called «joy-stick», comprised for example in a manipulator, comprising a housing (2) and projecting therefrom a control lever (3), which at its end located in the housing is hinged. According to the invention, a sleeve (13) is mounted concentrically about the lever (3), which sleeve (13) at one end is provided with a conic surface (14) intended by action of a spring force on the sleeve (13) to abut a plate (15) with a slide surface (16). The slide surface (16) includes a portion (17) with a conic surface so formed that the conic surface (14) of the sleeve upon abutment to the conic surface of the slide surface (16) is centered with respect to the slide surface to a non-operative position. By the invention a sturdy and simple device is obtained, which simply can be modified with respect to the force required for moving the lever (3) from its non-operative position. Modifications of the cross-sectional profile of the slide surface (16) yield different characteristics with respekt to said force required.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 135 words
A device at multi-way lever, so-called "joy-stick", comprised for example in a manipulator, comprising a housing and projecting therefrom a control lever, which at its end located in the housing is hinged, characterized i n that a sleeve (13) is mounted concentrically about the lever (3), which sleeve (13) at one end is provided with a conic surface (14) intended by action of a spring force on the sleeve (13) to abut a plate (.15) with a slide.surface (16), which slide surface includes a central portion (17) with a conic surface and outside thereof a concave portion to the sleeve, which conic surface is designed so that the conic surface (14) of the sleeve (13) upon abutment to to the conic surface.of the slide surface (16) is centered with repsct to the slide surface (16).
Claim 2
Independent Claim 135 words
A device at multi-way lever, so-called "joy-stick", comprised for example in a manipulator, comprising a housing and projecting therefrom a control lever, which at its end located in the housing is hinged, characterized i n that a sleeve (13) is mounted concentrically about the lever (3), which sleeve (13) at one end is provided with a conic surface (14) intended by action of a spring force on the sleeve (13) to abut a plate (.15) with a slide.surface (16), which slide surface includes a central portion (17) with a conic surface and outside thereof a concave portion to the sleeve, which conic surface is designed so that the conic surface (14) of the sleeve (13) upon abutment to to the conic surface.of the slide surface (16) is centered with repsct to the slide surface (16).
Claim 3
Dependent Claim 50 words
A device as defined in claim 1, characterized i n that the sleeve is located about the lever (3) between the free end of the lever and said plate (15), and that the slide surface (16) of the plate (15) is directed to the free end of the lever (3).
Claim 4
Dependent Claim 91 words
A device as defined in claim 1 or 2, characterized in that the height of the plate (15,21) varies with the radial distance from the conic portion (17) and outward, at the same time as its height varies in circumferential direction, preferably according to a sinus shape, so that the variation in height in circumferential direction is greatest at the outer periphery (22) of the plate (21) and smallest or insignificant at the transition of the conic portion (17) to the portion of the slide surface (16) which is located outside.
Claim 5
Dependent Claim 58 words
A device as defined in claim 3, characterized i n that said variation in height is such, that the height of the plate (21) in radial direction is highest in four mutually perpendicular directions (24-27) and lowest in four perpendicular directions (28-31), which lastmentioned directions (28-31) are offset 45 in circumferential direction relative to said firstmentioned directions (24-27).
Claim 6
Dependent Claim 53 words
A device as defined in claim 1 or 2, characterized in that the plate (15) is axial-symmetric, and the height of the plate (15) varies with the radial distance from the conic portion (17) and outward, so that the height increases substantially in said direction close to the periphery of the plate (15,33,34).
