Abstract
A weight is guided for free movement in a horizontal plane but is urged to a home position by the transmission mechanism which connects the weight to an actuated device. A ball with a flat face is seated in a cup and has an extension with a further ball received in an upstanding tube on the weight. A plunger with a button face engaging the flat face of the ball is spring urged to force such ball to that position which forces the weight to home position and the actuated device responds to movement of the plunger from such position.
Claims14
In a safety system, the combination of a housing having a base plate portion and an annular guide surface means in spaced parallel relation to said base plate portion, a disc shaped mass captive between said base plate portion and said annular guide surface means and having an upstanding tubular member extending upwardly through the center of said annular guide surface means so that the disc is movable in a generally horizontal plane within the limits dictated by engagement of said tubular member with said guide surface means, said housing also including ball seat means concentric with said annular guide surface means and having an opening centrally thereof, a semispherical ball member seated in said ball seat means and having a ball extension received within said tubular member, said ball member having a flat upper surface disposed generally horizontally when said ball extension is centered with respect to said annular guide surface means, said housing also incuding a guide sleeve above said flat upper surface and concentric with said annular guide surface means, a plunger reciprocably received in said guide sleeve and having a button-like lower end engaging said flat upper surface so that said plunger is moved upwardly as said disc is moved from its home position and said flat upper surface is tilted, spring means urging said plunger downwardly for normally urging said disc to its home position, and means responsive to upward movement of said plunger for actuating a safety device.
In a safety system including a safety device to be actuated in response to an acceleration force exceeding a predetermined magnitude, a mass for sensing acceleration force, guide means for constraining said mass to move in a generally horizontally path, and transmission means connecting said mass to said device for normally forcing said mass to a home position and for actuating said device in response to movement of said mass from said home position, said transmission means comprising a tilting element connected with the mass through a first ball joint and journalled on a frame through a second ball joint and provided with an annular tilting rim and a downwardly spring-loaded pressure element slidably journaled in the frame opposite the tilting rim and cooperating with the tilting rim.
In a safety system including a safety device to be actuated in response to an acceleration force exceeding a predetermined magnitude, a mass for sensing acceleration force, guide means for constraining said mass to move in a generally horizontal path, and transmission means connecting said mass to said device for normally forcing said mass to a home position and for actuating said device in response to movement of said mass from said home position, the transmission means comprising a time delay device transferring the movements of the mass with time delay to the safety device.
In a safety system including a safety device to be actuated in response to an acceleration force exceeding a predetermined magnitude, a mass for sensing acceleration force, guide means for constraining said mass to move in a generally horizontal path, and transmission means connecting said mass to said device for normally forcing said mass to a home position and for actuating said device in response to movement of said mass from said home position, said transmission means comprising an arcuate member having a pivot center displaced from said path and an extension engaging said mass.
