A push-in-plunger-lock and a housing-cylinder comprising:
- I) the push-in-plunger-lock comprising:
- a) a first-cylinder comprising:
- i) a first end without an end cap;
- ii) a second end with an end cap and a first hole in the end cap;
- iii) a lengthwise slot in the wall of the first-cylinder;
- and
- iv) a second hole in the wall of the first-cylinder;
- b) a second-cylinder being rotatably connected to a round cylindrical plunger, the plunger linearly extending through the first-cylinder second end first hole, the second-cylinder being lockable and un-lockable to the plunger with a key;
- c) the second-cylinder surrounding a portion of the plunger, the rotation of the plunger in the second-cylinder allows the plunger to be released from a linear locked position in the first-cylinder creating an unlocked position of the plunger, the second-cylinder moves in a linear motion with the plunger, the second-cylinder is non-rotatable within the first-cylinder;
- d) the key for rotating the position of the plunger within the first-cylinder and the second-cylinder;
- e) the second-cylinder movable in a linear direction in the first-cylinder first end;
- f) a pressure-inducing-device creating outward pressure between the first-cylinder second end and the second-cylinder;
- g) a first-securing-device in the first-cylinder able to interact with a grooved-notch in the plunger for locking the plunger in a linear position in the first-cylinder;
- h) the grooved-notch positioned perpendicular to the plunger length, the grooved-notch cutting across approximately sixty degrees of a circumference of the plunger, viewing the plunger in a vertical position and the second-cylinder at the bottom of the plunger:
- i) a top side and a bottom side of the grooved-notch are at a ninety degree angle from a grooved-notch floor;
- ii) the left and the right side of the grooved-notch floor slopes into the round circumference of the plunger allowing a smooth transition of the first-securing-device from the grooved-notch onto the round circumference of the plunger, therefore, unlocking the plunger from the first-cylinder linear locked position;
- iii) the top and bottom side of the grooved-notch enables the plunger to be linearly locked in place in the first-cylinder near the first-cylinder second end, when the grooved-notch is pushed to the first securing device, the first-securing-device inserts itself into the grooved-notch to lock the plunger linearly in place;
- and
- iv) the left and the right side of the grooved-notch enables the plunger to become unsecured from the first-securing-device during a rotation of the plunger by the key, the first-securing-device interacting with and exiting the floor of the grooved-notch to free the grooved-notch from the first-securing-device, therefore, allowing a linear retraction of the plunger within the first-cylinder creating an unlocked position of the push-in-plunger-lock;
- i) a second-securing-device attached to the second-cylinder secures the alignment of the second-cylinder in the first-cylinder slot, the second-securing-device moves inside the first-cylinder slot and provides a stop position at the first end of the first-cylinder slot preventing the second-cylinder from completely exiting the first-cylinder first end, the first end of the first-cylinder slot being near the first end of the first-cylinder;
- j) a first-clearance-area between the inner wall of the first-cylinder and the plunger, the first-clearance-area being approximately equal to the difference of the inner wall of the first-cylinder and the outer edge of the first hole of the first-cylinder second end;
- k) with the push-in-plunger-lock moved to the locked position, the second-cylinder passes by the first-cylinder second hole, therefore covering and eliminating the first-clearance-area at the second hole location;
- l) with the push-in-plunger-lock in the unlocked position, the second hole provides an access opening to the first-clearance-area;
- II) the housing-cylinder comprising;
- a) a first open end and a second open end, the first open end utilized for attaching to a lockable device such as a ratchet chain binder, the second open end utilized for the insertion of the push-in-plunger-lock;
- b) a third hole in the housing-cylinder aligns with the push-in-plunger-lock first-cylinder second hole after insertion of the push-in-plunger-lock first-cylinder into the housing-cylinder;
- c) a cylinder-pin that fits into the housing-cylinder third hole in a very tight fit and the cylinder-pin to fits into the first-cylinder second hole in a loose fit, mandating the housing-cylinder third hole comprise a smaller diameter hole when compared to any diameter of the first-cylinder second hole, and therefore, attaching the housing-cylinder to the first-cylinder,
- d) the cylinder-pin in an installed-position maintains a locked-position of the push-in-plunger-lock first-cylinder and the housing-cylinder, the installed-position of the cylinder-pin is when the cylinder-pin is positioned in the housing-cylinder third hole and the first-cylinder second hole without entering the first-clearance-area of the push-in-plunger-lock, in the installed position;
- i) the cylinder-pin prevents the first-cylinder from being removed from the housing-cylinder;
- and
- ii) the outward facing end of the cylinder-pin being even or nearly even with the outer surface of the housing-cylinder preventing a pulling or turning outward removal of the cylinder-pin from the housing-cylinder third hole or from the first-cylinder second hole;
- e) with the push-in-plunger-lock is in the locked position and the cylinder-pin residing in the installed-position, the cylinder-pin is prevented by the second-cylinder from being pushed into the first-clearance-area of the push-in-plunger-lock, therefore maintaining the installed-position of the cylinder-pin and maintaining the locked-position of the first-cylinder in the housing-cylinder preventing the push-in-plunger-lock from being removed from the housing-cylinder;
- and
- f) with the push-in-plunger-lock is in the unlocked position and the second-cylinder moved away from the first-cylinder second hole, the cylinder-pin is enabled to be pushed into the first-clearance-area dislodging the cylinder-pin from the housing-cylinder third hole resulting in the first-cylinder being unsecured from the housing-cylinder allowing the push-in-plunger-lock to be removed from the housing-cylinder.
