Abstract
A delayed actuator mechanism with visco-elastic timer is provided including a support section and an actuator section mounted to the support section. A compression spring biases the actuator section in a first state and permits the actuator section to be selectively switched to a second state. In that state a cocked torsion spring urges a detent carried by the actuator into engagement with a shoulder of the support section to restrain the actuator section in the second state. A visco-elastic delay mechanism gradually relaxes the torsion spring until the compression spring overcomes the detent shoulder restraint to abruptly switch the actuator section to the first state.
Claims31
A delayed actuator mechanism with visco-elastic timer comprising:
- a support section;
- an actuator section mounted to said support section;
- biasing means for urging said actuator section into a first state and permitting said actuator section to be selectively switched to a second state;
- means for restraining said actuator section in said second state;
- and
- visco-elastic delay means for gradually releasing said means for restraining until said biasing means overcomes said means for restraining to abruptly switch said actuator section to said first state.
A delayed fluid dispenser with visco-elastic timer comprising:
- a support section having a reservoir for containing a fluid and port means for dispensing said fluid;
- an actuator section mounted to said support section;
- biasing means for urging said actuator section into a first state and permitting said actuator section to be selectively switched to a second state;
- means for temporarily restraining said actuator section in said second state;
- visco-elastic delay means for gradually releasing said means for restraining until said biasing means overcomes said means for restraining to abruptly switch said actuator section to said first state;
- and
- means responsive to said actuator section in one of said first and second states for accelerating vaporization of said fluid in said reservoir and dispensing of said fluid through said port means.
A delayed fluid dispenser with visco-elastic timer comprising:
- a support section having a reservoir for containing a fluid and port means for dispensing said fluid;
- an actuator section mounted to said support section;
- biasing means for urging said actuator section into a first state and permitting said actuator section to be selectively switched to a second state;
- means for restraining said actuator section in said second state;
- visco-elastic delay means for gradually releasing said means for restraining until said biasing means overcomes said means for restraining to abruptly switch said actuator section to said first state;
- and
- closure means for closing to cover said port means in response to said actuator means being in one of said first and second states and opening to uncover said port means in response to said actuator means being in the other said state.
A delayed actuator mechanism with visco-elastic timer comprising:
- a support section;
- an actuator section mounted to said support section;
- biasing means for urging said actuator section into a first state and permitting said actuator section to be selectively switched to a second state;
- means for restraining said actuator section in said second state;
- and
- visco-elastic delay means for gradually releasing said means for restraining until said biasing means overcomes said means for restraining to abruptly switch said actuator section to said first state;
- and
- said means for restraining including first gear means operably connected to said visco-elastic delay means and complementary second gear means connected to said actuating section and responsive to said biasing means for driving said first gear means until said second gear means disengages said first gear means and said actuator section is abruptly switched to said first state.
