Brake mechanism
First Claim
1. A brake mechanism comprising:
- an axially extending input having first and second ends;
a chassis interfacing with the input such that the input is movable relative to the chassis;
a lock coupled to the chassis for constraining movement of the input relative to the lock; and
a release mechanism coupled to the lock and responsive to a force applied relative to the input and the chassis such that when the force is greater than a release force the release mechanism allows the lock to disengage the input and such that when the force is less than the release force the release mechanism does not allow the lock to disengage the input.

Abstract
A brake mechanism includes an input, a chassis, a lock and a release mechanism. The input is an axially extending input having first and second ends. The chassis interfaces with the input such that the input is movable relative to the chassis. The lock is coupled to the chassis for constraining movement of the input relative to the lock. The release mechanism is coupled to the lock and is responsive to a force applied relative to the input and the chassis such that when the force is greater than a release force level the release mechanism allows the lock to disengage the input and such that when the force is less than the release force level the release mechanism does not allow the lock to disengage the input.

15. A brake mechanism for controllably regulating relative motion between a first body and a second body, the brake mechanism comprising:
-
an axially extending input having first and second ends, the first end being coupled to the first body;
a chassis coupled to the second body, the chassis configured to interface with the input and configured such that the input is movable relative to the chassis;
a lock coupled to the chassis, the lock having a first state in which the lock constrains movement of the input relative to the lock and the lock having a second state in which the lock allows movement of the input relative to the lock; and
a release mechanism coupled to the lock and responsive to a force applied relative to the first and second bodies such that when the applied force is greater than a release force the release mechanism causes the lock to be in the first state and such that when the applied force is less than the release force the release mechanism causes the lock to be in the second state. - View Dependent Claims (16, 17, 18)

19. A brake mechanism for controllably regulating relative motion between a first body and a second body, the brake mechanism comprising:
-
an axially extending input having first and second ends, the first end being coupled to the first body;
a chassis coupled to the second body, the chassis configured to interface with the input and configured such that the input is movable relative to the chassis;
a force mechanism configured for engagement with the chassis;
a lock holder configured adjacent the force mechanism and having a first recess;
a first locking plate received within the recess of the lock holder and configured to variably engage the input dependant upon a force applied relative to the first and second bodies. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A brake mechanism for controllably regulating relative motion between a first body and a second body, the brake mechanism comprising:
-
an axially extending input having first and second ends, the first end being coupled to the first body;
a housing coupled to the second body, the housing configured to interface with the input and configured such that the input is movable relative to the housing;
a release slide within the housing configured to slide relative to the input;
a shaft extending through the release slide generally perpendicular to the axially extending input;
a pinion coupled to the shaft;
a first wrap spring clutch configured about the shaft; and
a first slip clutch configured about the shaft;
wherein the first wrap spring clutch is configured to variably engage the input dependant upon a force applied relative to the first and second bodies. - View Dependent Claims (29, 30, 31)

32. A brake mechanism for controllably regulating relative motion between a first body and a second body, the brake mechanism comprising:
-
an axially extending shaft having first and second ends, the first end being coupled to the first body;
a chassis coupled to the second body, the chassis configured to interface with the shaft and configured such that the shaft is movable relative to the chassis;
a force generator that generates a compression force, the force generator configured for engagement with the chassis;
a lock holder configured to receive the compression force from the force generator, the lock holder having a first and a second recess;
first and second locking plates received within the first and second recesses of the lock holder that are each configured with openings through which the shaft extends;
a detent feature in communication with the lock holder and the force generator.
