Abstract
A progressive release or multi-point engagement device according to aspect of the present disclosure includes a first component and a second component connected to the first component with mounted coil spring. The first component is movable relative to the second component and latch by moving the canted coil spring to a second common groove. Alternatively, a second spring is used to move the second component and relative to a third component. When a second engagement position is desired, a relatively higher a force may be necessary to move the relevant component.
Claims12
A device with multi-stage engagement comprising:
- a first component defining a first axis;
- a second component defining a second axis connected to the first component with a first canted coil spring captured by a groove located on the second component and a groove located on the first component;
- a third component defining a third axis connected to the second component with a second canted coil spring;
- and
- wherein the first, second, and third axes are common to one another and define a common axis, and a force required to release the connection between the second component and the third component is less than a force required to release the connection between the first component and the second component, and wherein the device has two release configurations including:
- a first release configuration in which the third component moves relative to the second component and relative to the first component along the common axis;
- and
- a second release configuration following the first release configuration in which movement of the third component causes the second component to move together with the third component but relative to the first component along the common axis.
A method of making a device with multi-stage engagement, the method comprising:
- releasably connecting a first component defining a first axis to a second component defining a second axis with a first canted coil spring captured by a groove located on the second component and a groove located on the first component, the connection being releasable with a first required force exerted on at least one of the first component or the second component;
- releasably connecting the second component to a third component defining a third axis with a second canted coil spring, the connection being releasable with a second required force exerted on at least one of the second component or the third component;
- wherein the first, second, and third axes are common to one another and define a common axis, and the second force is less than the first force, and
- wherein the device has two release configurations including:
- a first release configuration in which the third component moves relative to the second component and relative to the first component along the common axis;
- and
- a second release configuration following the first release configuration in which movement of the third component causes the second component to move together with the third component but relative to the first component along the common axis.
