Abstract
In a door latch system having a metal latching member engageable with a metal striker, a noise suppressor of resilient material is dovetail jointed to the latching member, in such a position thereon that the striker makes noiseless contact therewith upon closure of the door. The latch further comprises a stop of resilient material arranged for contact with the striker in a fully latched position, and a guide of relatively rigid, wear-resistant material extending along a striker guideway in the main body of the latch.
Claims13
A latch comprising a main body defining therein a striker guideway into and out of which a striker is movable, a latching member rotatably disposed across the striker guideway within the main body and having a recess for engagement with the striker, means for controllably restraining the latching member from rotation in one direction, a shaft rotatably supporting the latching member, and a noise suppressor member of resilient material substantially integrally attached to the latching member so as to define part of the recess, said noise suppressor member being so arranged on the latching member as to collide with the striker upon entrance thereon into the striker guideway, said noise suppressor member comprising a mounting plate having a hole for receiving said shaft and a noise suppressor proper formed integral with the mounting plate and secured directly to the latching member.
A latch comprising a main body defining therein a striker guideway into and out of which a striker is movable, a metal latching member mounted within said main body in a manner rotatable about a rotating axis, said latching member being disposed across the striker guideway and having a recess for engagement with the striker, said recess having a cutout, receding from the contour of the recess, along only one side part thereof with which the striker is in contact during its advance into and along the striker guideway, a swingable ratchet member having a pawl engageable with the latching member to controllably restrain the latching member from rotation in one direction, and a noise suppressor member of resilient material immovably fitted in said cutout so as to define the contour of the recess along said side part of the recess, said noise suppressor member extending over the full dimension of the latching member with respect to the direction of said rotation axis.
