Abstract
A casket lock structure for securing a casket top in a closed and sealed position. An elongated lock bar is slideably mounted inside the front of a casket. A connecting bar is pivotally mounted at one end to the lock bar and at the other end to an offset portion of a shaft extending through the wall of the casket such that rotation of the shaft causes a lateral translational movement of the lock bar. Striker pins fastened to the casket top are adapted to engage hook portions formed into the lock bar as the top is closed.
Claims12
A casket lock structure for securing a casket top in a closed and sealed position comprising:
- an elongated lock bar and means for slidably mounting it along a casket wall, said bar having at least one hook portion;
- a shaft to be rotatably supported through the casket wall at a point intermediate the length of the lock bar;
- means for rotating said shaft;
- a connecting bar having one end pivotally mounted to the lock bar at a point laterally offset from said shaft, offset means on said shaft being so associated with the other end of the said connecting bar that rotation of said shaft causes a lateral translational movement of the said one end of the connecting bar and, in turn, the lock bar to which it is mounted;
- and,
- means associated with the casket top for engaging said hook portion of the lock bar as the top is closed;
- said lock structure having a locked position corresponding to the closed and sealed position of the casket top;
- and
- said lock bar, connecting bar and offset means being so connected and arranged relative to one another that the angular displacement of the handle required to produce a small uniform downward displacement of the casket top increases as the lock structure approaches its locked position, thereby increasing the leverage of shaft rotation to lock bar translation so as to maximize the closing force applied to the casket top as it approaches its closed and locked position.
A casket lock structure for securing a casket top in a closed and sealed position comprising:
- an elongated lock bar and means for slidably mounting it along a casket wall, said bar having at least one hook portion;
- a shaft to be rotatably supported through the casket wall at a point intermediate the length of the lock bar;
- means for rotating said shaft;
- a connecting bar having one end pivotally mounted to the lock bar at a point laterally offset from said shaft, offset means on said shaft being so associated with the other end of said connecting bar that rotation of said shaft causes a lateral translational movement of the said other end of the connecting bar and, in turn, the lock bar to which it is mounted;
- means associated with the casket top for engaging said hook portion of the lock bar as the top is closed;
- and
- a locking bracket slidably mounted along said lock bar, spring means urging said locking bracket toward the said other end of the connecting bar, said locking bracket having a slanted edge surface so that as the said other end of the connecting bar approaches the end of its rotational displacement, it will bear against the slanted edge portion of the locking bracket and be urged toward its final locked position.
A casket lock structure for securing a casket top in a closed and sealed position comprising:
- an elongated lock bar and means for slidably mounting it along a casket wall, said bar having at least one hook portion;
- a shaft to be rotatably supported through the casket wall at a point intermediate the length of the lock bar;
- a longitudinal slot in said lock bar, said slot permitting the translational displacement of the lock bar about said shaft which extends therethrough;
- means for rotating said shaft;
- a connecting bar having one end pivotally mounted to the lock bar at a point laterally offset from said shaft, offset means on said shaft being so associated with the other end of said connecting bar that rotation of said shaft causes a lateral translational movement of the said other end of the connecting bar and, in turn, the lock bar to which it is mounted;
- means associated with the casket top for engaging said hook portion of the lock bar as the top is closed.
