Lock with a Rotational Indicator of Status
First Claim
1. A lock including:
- a body;
a key-operable locking mechanism placed in the body, wherein the key-operable locking mechanism includes;
a core including a key hole in a front end; and
a block connected to a rear end of the core and formed with an axial protrusion, an upper radial protrusion on an upper face of the axial protrusion, a lower radial protrusion on a lower face of the axial protrusion, wherein the core can rotate the block about the axial protrusion into an unlocking position from a locking position; and
an indicator placed in the body and formed with a recess for receiving the block, wherein the recess includes a first wall for contact with the upper radial protrusion of the block and a second wall for contact with the lower radial protrusion of the block, wherein the indicator is rotatable into an indicating position from an original position;
wherein the upper radial protrusion of the block abuts the first wall of the recess to rotate the indicator into the indicating position from the original position when the core rotates the block into the unlocking position, wherein there is a gap between the lower radial protrusion of the block and the second wall of the recess to allow the lower radial protrusion of the block to move toward the second wall of the recess when the core returns the block into the locking position.

Abstract
A lock includes a body, a key-operable locking mechanism and a rotational indicator. The locking mechanism includes a spindle and a block. The spindle includes a key hole in an end and is connected, at another end, to the block to allow the block to be rotated from a locking position to an unlocking position. The indicator is disposed in the lock body, and includes, at a front end, a recess for receiving the block. With the indicator in the original position, as the block is rotated to the unlocking position, the block pushes a first side wall of the recess of the indicator to rotate the indicator to an indicating position. When the indicator is in the indicating position, a space is defined between a second side wall of the recess of the indicator and the block, and the block is moved in the space.

6. A lock including:
-
a receptacle; a tongue detachably engaged with the receptacle; a strap connected to the receptacle at an end and connected to the tongue at another end; a key-operable locking mechanism placed in the receptacle, wherein the key-operable locking mechanism includes; a core including a key hole in a front end; and a block connected to a rear end of the core and formed with an axial protrusion, an upper radial protrusion on an upper face of the axial protrusion, a lower radial protrusion on a lower face of the axial protrusion, wherein the core can rotate the block about the axial protrusion into an unlocking position from a locking position; and an indicator placed in the receptacle and formed with a recess for receiving the block, wherein the recess includes a first wall for contact with the upper radial protrusion of the block and a second wall for contact with the lower radial protrusion of the block, wherein the indicator is rotatable into an indicating position from an original position; wherein the upper radial protrusion of the block abuts the first wall of the recess to rotate the indicator into the indicating position from the original position when the core rotates the block into the unlocking position, wherein there is a gap between the lower radial protrusion of the block and the second wall of the recess to allow the lower radial protrusion of the block to move toward the second wall of the recess when the core returns the block into the locking position.
