Abstract

A shuttle lock for use with an artificial limb comprises an upper assembly, a lower assembly, and a locking mechanism. The upper assembly includes a cutout for a channel with a wide portion and a narrow portion, and a lip around an outer edge of the upper assembly such that a groove does not extend to the outer edge of the upper assembly. The lower assembly includes a platform that surrounds a portion of an aperture, two spring pockets, a cutout complementary to the cutout of the upper assembly. A locking-mechanism pocket extends from the spring pockets to surround the aperture and includes a middle portion and two side portions that flank the middle portion. The middle portion is raised above the side portions and includes a width less than a width of the platform. A bottom of the lower assembly includes a sunken portion terminating before coupling holes.

Dependent claims

A shuttle lock for use with an artificial limb, the shuttle lock comprising:

an upper assembly including:
an aperture for receiving a coupler;
a cutout for a channel, wherein the cutout includes a wide portion and a narrow portion;
a groove on a surface of the upper assembly, wherein the groove extends radially from the aperture toward an outer edge of the upper assembly;
and
a lip around the outer edge of the upper assembly such that the groove does not extend to the outer edge of the upper assembly;
a lower assembly including:
an aperture that aligns with the aperture of the upper assembly when the upper assembly and the lower assembly are coupled together;
a platform that surrounds a portion of the aperture of the lower assembly, wherein the platform includes a width;
a first spring pocket located co-radially with the aperture of the lower assembly;
a second spring pocket located non-radially with the aperture of the lower assembly, wherein the second spring pocket is longer than the first spring pocket;
a cutout, wherein the cutout includes a wide portion and a narrow portion, such that when the upper assembly and the lower assembly are coupled together, the channel is formed;
a locking-mechanism pocket that:
extends from the first spring pocket and the second spring pocket and surrounds the aperture of the lower assembly;
includes a middle portion;
and
includes two side portions that flank the middle portion, wherein the middle portion is raised compared to the side portions and includes a width less than a width of the platform;
a bottom including:
a collar surrounding the aperture of the lower assembly, wherein the collar protrudes away from a surface of the bottom;
coupling holes that are flush with the surface of the bottom;
and
a sunken portion extending from the collar and terminates before the coupling holes;
and
a locking mechanism including:
a lock plate with an aperture that fits around the platform;
a pin that fits into the channel and abuts the lock plate such that when a user activates the pin, the lock plate traverses within the locking-mechanism pocket to unlock the shuttle lock;
a first spring within the first spring pocket, wherein the first spring biases the lock plate linearly to be locked;
and
a second spring within the second spring pocket, wherein the second spring adds tension to the lock plate.
