Abstract
A latch may include a follower and a driver. The follower may include a follower opening configured to receive a post of a housing. The driver may include a driver opening configured to receive the post of the housing such that the driver is selectively rotatable relative to the post. The driver may further include an interfacing finger positioned to be received by the follower opening. The interfacing finger may be configured to urge the follower to slidingly move relative to the housing as the driver is rotated relative to the post.
Claims18
A latch comprising:
- a follower including a follower opening configured to receive a post of a housing:
- the post of the housing including a partially cylindrical portion including a flat surface and a flange configured to maintain a driver on the post;
- and
- the driver including:
- a driver opening including a slot portion and a rounded portion wider than the slot portion, the driver opening configured to receive the post of the housing such that the driver is selectively rotatable relative to the post, the slot portion sized to receive the partially cylindrical portion of the post when in an aligned orientation relative to the flat surface and not to receive the partially cylindrical portion of the post when not in the aligned orientation relative to the flat surface;
- and
- an interfacing finger positioned to be received by the follower opening, wherein the interfacing finger is configured to urge the follower to slidingly move relative to the housing as the driver is rotated relative to the post.

A module comprising:
- a housing including a post including a partially cylindrical portion including a flat surface and a flange configured to maintain a driver on the post;
- a follower including a follower opening shaped to slide relative to the post as the follower slides relative to the housing;
- and
- the driver including:
- a driver opening including a slot portion and a rounded portion wider than the slot portion, the driver opening shaped to rotate relative to the post as the driver is rotated between a latched position and an unlatched position, the slot portion sized to receive the partially cylindrical portion of the post when in an aligned orientation relative to the flat surface and not to receive the partially cylindrical portion of the post when not in the aligned orientation relative to the flat surface;
- and
- an interfacing finger positioned to be received by the follower opening, wherein the interfacing finger is configured to:
- urge the follower to a latched position relative to the housing as the driver is rotated from the unlatched position to the latched position, and urge the follower to an unlatched position relative to the housing as the driver is rotated from the latched position to the unlatched position.
5 more elements
A module comprising:
- a housing including:
- posts, each including:
- a partially cylindrical portion including a flat surface;
- and a flange configured to maintain a driver on the posts;
- channels;
- and depressions;
- a follower including:
- follower arms, each including an unlatch projection;
- follower openings sized and positioned to receive the posts of the housing and to slide relative to the posts as the follower slides relative to the housing;
- and a detent protuberance;
- and
- the driver including:
- driver arms including driver openings, each of the driver openings including a slot portion and a rounded portion wider than the slot portion, the slot portions being configured to receive the partially cylindrical portion of the posts when in an aligned orientation relative to the flat surface and being configured not to receive the partially cylindrical portion of the posts when not in the aligned orientation relative to the flat surface, the driver openings sized and positioned to:
- receive the posts;
- and rotate relative to the posts as the driver is rotated between a latched position and an unlatched position;
- interfacing fingers positioned to be received by the follower openings of the follower and the channels of the housing;
- and a detent projection, wherein the interfacing fingers are sized and positioned to:
- urge the follower to a latched position relative to the housing as the driver is rotated from its unlatched position to its latched position;
- and
- urge the follower to an unlatched position relative to the housing as the driver is rotated from its latched position to its unlatched position;
- and wherein the detent projection and the detent protuberance are positioned such that the detent projection is resiliently deformed to create a resistance to be overcome to rotate the driver from the latched position to the unlatched position.
