Abstract
A lock system includes a swing latch, one or more pins, and a channel. The swing latch includes a latch arm having a keyed profile at a first end and a swing bar extending from a second end. The one or more pins have a hook portion and a peg portion. The hook portion defines an aperture. The hook portion is configured to engage the swing bar and the aperture is configured to release the swing bar. The channel is configured to accommodate a rotational movement of the swing latch, such that, responsive to the aperture aligning with the swing bar, the swing latch is permitted to rotate through the channel.
Claims20
A lock system comprising:
- a swing latch including a latch arm having a keyed profile at a first end and a swing bar extending from a second end;
- one or more pins having a hook portion and a peg portion, the hook portion defining an aperture, wherein the hook portion is configured to engage the swing bar and the aperture is configured to release the swing bar;
- and
- a channel configured to accommodate a rotational movement of the swing latch, such that, responsive to the aperture aligning with the swing bar, the swing latch is permitted to rotate through the channel;
- wherein at least one of:
- (a) the lock system further comprises a key configured to lift the one or more pins to align the aperture with the swing bar and rotate the swing latch, the key including a shaft with a sleeve rotatable about the shaft, the sleeve having a first keyed blade;
- (b) the swing latch includes a cam bar positioned proximate the first end of the latch arm, opposite the keyed profile;
- or
- (c) the lock system further comprises an internal locking mechanism including:
- a second keyed blade coupled with a spring,
- a first gear coupled with the swing latch and positioned opposite the keyed profile,
- a second gear rotatably engaged with the first gear, wherein rotation of the first gear causes rotation of the swing latch and the second gear;
- and
- a tapered member coupled to the second gear, the tapered member configured to push the second keyed blade to compress the spring.

A lock system comprising:
- a key including:
- a bow;
- a shaft extending from the bow, the shaft having a keyed profile at a free end thereof;
- a sleeve rotatably coupled around the shaft;
- and
- a keyed blade extending from the sleeve;
- wherein at least one of:
- (a) the sleeve is a first sleeve and the keyed blade is a first keyed blade, wherein the first sleeve is removable from the shaft, further comprising a second sleeve with a second keyed blade that is different from the first keyed blade, wherein the second sleeve is configured to replace the first sleeve;
- (b) the first keyed blade is removable from the sleeve and the second keyed blade is configured to replace the first keyed blade;
- (c) the sleeve defines a slot, wherein the shaft includes a tab received in the slot, and wherein the slot permits partial rotation of the tab and, therefore, the shaft relative to the sleeve;
- or
- (d) the keyed profile is a first keyed profile and the lock system further comprising a lock including:
- a swing latch including a latch arm having a second keyed profile at a first end and a swing bar extending from a second end;
- and
- one or more pins having a hook portion and a peg portion, the hook portion defining an aperture, wherein the hook portion is configured to engage the swing bar and the aperture is configured to release the swing bar;
- wherein the keyed blade is configured to lift the one or more pins to align the aperture with the swing bar and the first keyed profile is configured to engage with the second keyed profile to facilitate rotating the swing latch to release the swing bar from the one or more pins to unlock the lock.

A key-operated lock system comprising:
- a key including:
- a shaft having a first keyed profile;
- and
- a sleeve disposed around the shaft, the sleeve including a keyed blade;
- and
- a lock assembly including:
- a plurality of pins, each of the plurality of pins having a top portion and bottom portion, the top portion defining an aperture;
- and
- a swing latch including:
- a second keyed profile;
- and
- a swing bar configured to engage with the top portion of the plurality of pins;
- wherein, when the key is inserted into the lock assembly, (a) the keyed blade engages with the bottom portion of the plurality of pins to lift the plurality of pins to align the apertures with the swing bar and (b) the first keyed profile of the shaft engages with the second keyed profile of the swing latch to facilitate rotating the swing latch to unlock the lock assembly.
