Abstract

Abstract A multidirectional sensor having an operator mounted within a guide tube and spring biased in one axial direction for movement from a first position to a second actuated position. The operator is constrained against movement by the engagement of a plurality of balls mounted within apertures in the wall of the guide tube with a shoulder of the operator. The balls are held against movement outwardly of the guide tube apertures by an internal annular wall of an annular pendulous seismic mass mounted on the guide tube for movement axially and rotationally thereof. The axis of the guide tube, the axis of pendulosity of the mass, and the axis of the mass are coaxial. This wall is interrupted by a plurality of equally spaced axial grooves and the balls normally engage the wall intermediate the grooves. Spring seats on spaced annular walls of the mass and a common stop on the sensor housing are engageable by opposing threshold springs to locate the mass against movement axially of the guide tube. One of the springs torsionally engages the mass to locate the mass against movement rotationally of the guide tube. The sensor can be externally reset when the operator is in actuated position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 99 words
A sensor comprising, in combination, a support, an operator mounted on the support for movement between first and second positions relative thereto, detent means operable to hold the operator in the first position against movement to the second position, a pendulous seismic mass, means mounting the mass on the support for bodily movement along the axis of pendulosity thereof and rotational movement about such axis, and means operably connecting the mass to the detent means to release the detent means from the operator upon either mode of movement of the mass relative to the axis through a predetermined distance.
Claim 2
Dependent Claim 99 words
A sensor comprising, in combination, a support, an operator mounted on the support for movement between first and second positions relative thereto, detent means operable to hold the operator in the first position against movement to the second position, a pendulous seismic mass, means mounting the mass on the support for bodily movement along the axis of pendulosity thereof and rotational movement about such axis, and means operably connecting the mass to the detent means to release the detent means from the operator upon either mode of movement of the mass relative to the axis through a predetermined distance.
Claim 3
Dependent Claim 119 words
A sensor comprising, in combination, a support, an operator mounted on the support for movement along a predetermined axis between first and second positions relative thereto, detent means operable to hold the operator in the first position against movement to the second position, a pendulous seismic mass, means mounting the mass on the support for bodily movement along the axis of pendulosity thereof and rotational movement about such axis, the axis of pendulosity being coaxial with the axis of movement of the operator, and means operably connecting the mass to the detent means to release the detent means from the operator upon either mode of movement of the mass relative to the axis of pendulosity through a predetermined distance.
Claim 4
Dependent Claim 119 words
A sensor comprising, in combination, a support, an operator mounted on the support for movement along a predetermined axis between first and second positions relative thereto, detent means operable to hold the operator in the first position against movement to the second position, a pendulous seismic mass, means mounting the mass on the support for bodily movement along the axis of pendulosity thereof and rotational movement about such axis, the axis of pendulosity being coaxial with the axis of movement of the operator, and means operably connecting the mass to the detent means to release the detent means from the operator upon either mode of movement of the mass relative to the axis of pendulosity through a predetermined distance.
Claim 5
Dependent Claim 107 words
A sensor comprising, in combination, a support, an operator mounted on the support for movement between first and second positions relative thereto, detent means operable to hold the operator in the first position against movement to the second position, a pendulous seismic mass, means mounting the mass on the support for bodily movement in either direction relative to the axis of pendulosity thereof and rotational movement in either direction relative to such axis, and means operably connecting the mass to the detent means to release the detent means from the operator upon either mode of movement of the mass relative to the axis through a predetermined distance.
