Latch and lock structure

Claim 2

Latch and lock structure for holding a door in a closed position with respect to a door frame, comprising: latch means having handle means pivotally mountable on said door for movement between latched and unlatched positions, said handle means having a C-shaped end portion opening radially relative to the pivot axis; bracket means adapted for rigid securement to said door adjacent said handle means when it is in said latched position; padlock means having shackle means rigidly secured to said bracket means and having body means supported upon said shackle means for movement between locked and unlocked positions, said body means being disposed between the two legs of said C-shaped portion, when said body means is in said locked position and said handle means is in its latched position for positively preventing material pivotal movement of said handle means.

Claim 3

Latch and lock structure according to claim 1 wherein, the door is upwardly acting and the handle means is pivotally mounted near the lower edge of said door; wherein said latch means includes bolt means pivotally mounted on said door for movement around said axis; and including catch means mounted to said door frame and engageable by said bolt means for positively holding said door adjacent said door frame when said handle means is in said latched position.

Claim 4

Latch and lock structure according to claim 1, wherein said bracket means includes a rectangular casing having parallel top and bottom walls and an end wall, said shackle means being rigidly secured to said end wall, and said top and bottom walls having aligned openings through which one leg and the bight of said C-shaped portion are receivable as said handle means is moved into the latched position, said body means being disposed within said casing for movement toward and away from said end wall.

Claim 5

Latch and lock structure for holding an upwardly acting door of a truck van in a closed position with respect to the truck bed said latch means having handle means moveable between latched and unlatched positions, comprising: brackets means adapted to be rigidly secured to said door adjacent said handle means when it is in the latched position; wall means on said handle means defining a recess opening in a direction substantially perpendicular to the direction of movement of said handle means as said handle means approaches said latched position; and padlock means having shackle means adapted to be rigidly secured to said bracket means, and having body means supported on said shackle means for movement relative thereto into and out of a locked position within said recess when said handle means is in said latched position.

Claim 6

Latch and lock structure for holding an upwardly acting door of a truck van in a closed position with respect to the truck bed said latch means having handle means moveable between latched and unlatched positions, comprising: brackets means adapted to be rigidly secured to said door adjacent said handle means when it is in the latched position; wall means on said handle means defining a recess opening in a direction substantially perpendicular to the direction of movement of said handle means as said handle means approaches said latched position; and padlock means having shackle means adapted to be rigidly secured to said bracket means, and having body means supported on said shackle means for movement relative thereto into and out of a locked position within said recess when said handle means is in said latched position.

Claim 7

In an upwardly acting door for the van of a truck having a bed with a catch recess therein and having a catch with a downwardly facing catch surface rigidly held within said recess, a door latch and lock structure, comprising: an actuating member pivotally mounted upon the door near the lower edge thereof for movement around a pivot axis parallel with said bed when said lower edge is adjacent thereto, said member having a recessed end portion remote from and opening radially of said axis; a latch bolt pivotally supported upon said door for movement around an axis parallel with the first mentioned axis and with respect to said actuating member, said latch bolt having a shank and elongated arcuate hook means extending sidewardly from said shank and adapted to extend below saiD lower edge of said door for snug engagement with said catch surface, whereby the lower edge of said door is held closely adjacent said bed; bracket means mounted upon said door and engageable by said actuating member when said actuating member is in a position holding said hook means engaged with said catch surface; and padlock means having shackle means, rigidly secured to said bracket means, and having body means movable into and out of a locking position within said recess in said end portion when said actuating member is in said holding position.

Claim 8

In an upwardly acting door for the van of a truck having a bed with a catch recess therein and having a catch with a downwardly facing catch surface rigidly held within said recess, a door latch and lock structure, comprising: an actuating member pivotally mounted upon the door near the lower edge thereof for movement around a pivot axis parallel with said bed when said lower edge is adjacent thereto, said member having a recessed end portion remote from and opening radially of said axis; a latch bolt pivotally supported upon said door for movement around an axis parallel with the first mentioned axis and with respect to said actuating member, said latch bolt having a shank and elongated arcuate hook means extending sidewardly from said shank and adapted to extend below saiD lower edge of said door for snug engagement with said catch surface, whereby the lower edge of said door is held closely adjacent said bed; bracket means mounted upon said door and engageable by said actuating member when said actuating member is in a position holding said hook means engaged with said catch surface; and padlock means having shackle means, rigidly secured to said bracket means, and having body means movable into and out of a locking position within said recess in said end portion when said actuating member is in said holding position.

Claim 9

A structure according to claim 5, including a mounting plate rigidly secured to said door and axle means pivotally supporting said actuating member and said latch bolt, said axle means being rigidly secured to said mounting plate.

Claim 10

A structure according to claim 5 including cooperating stop means on said shackle means and said body means preventing disconnection of said body means from said shackle means.
