Mechanical latch module
First Claim
1. A latch module, for connecting to a retaining pin of a chassis, comprising:
- a button carriage comprising a user-operable button,wherein the button carriage is slidably coupled to a latch module chassis of the latch module, thereby enabling the button carriage to move between an extended and a depressed position with respect to the latch module chassis, andwherein the button carriage, when the button is depressed a first time, moves from the extended position to the depressed position;
an inverter arm,wherein the inverter arm is pivotally coupled to the latch module chassis,wherein the inverter arm is mechanically linked to the button carriage at a first end of the inverter arm, andwherein the button carriage, moving from the extended position to the depressed position, as the button is depressed, causes the inverter arm to pivot;
a latch arm, mechanically linked to a second end of the inverter arm,wherein the latch arm is slidably coupled to the latch module chassis,wherein pivoting of the inverter arm causes the latch arm to slide from a non-blocking position into a blocking position,wherein, in the blocking position, the latch arm extends toward and makes contact with the retaining pin of the chassis, andwherein, in the non-blocking position, the latch arm is away from and not in contact with the retaining pin of the chassis; and
a latch biasing spring between the button carriage and the inverter arm, generating a biasing force that, in the blocking position, causes the inverter arm to exert a force against the retaining pin.

Abstract
A latch module that includes a button carriage that is slidably coupled to a latch module chassis, thereby enabling the button carriage to move between an extended and a depressed position. The button carriage, when a user-operable button of the button carriage is depressed a first time, moves from the extended position to the depressed position. An inverter arm that is pivotally coupled to the latch module chassis and that is mechanically linked to the button carriage pivots when the button carriage, moves from the extended position to the depressed position, as the button is depressed. A latch arm that is mechanically linked to the inverter arm slides from a non-blocking position into a blocking position when the inverter arm pivots. In the blocking position, the latch arm extends beyond a retaining pin of a chassis; and in the non-blocking position, the latch arm clears the retaining pin.

12. A latch module, for connecting to a retaining pin of a chassis, comprising:
-
a button carriage comprising a user-operable button, wherein the button carriage is slidably coupled to a latch module chassis of the latch module, thereby enabling the button carriage to move between an extended and a depressed position with respect to the latch module chassis, and wherein the button carriage, when the button is depressed a first time, moves from the extended position to the depressed position; an inverter arm, wherein the inverter arm is pivotally coupled to the latch module chassis, wherein the inverter arm is mechanically linked to the button carriage at a first end of the inverter arm, and wherein the button carriage, moving from the extended position to the depressed position, as the button is depressed, causes the inverter arm to pivot; a latch arm, mechanically linked to a second end of the inverter arm, wherein the latch arm is slidably coupled to the latch module chassis, wherein pivoting of the inverter arm causes the latch arm to slide from a non-blocking position into a blocking position, wherein, in the blocking position, the latch arm extends toward and makes contact with the retaining pin of the chassis, and wherein, in the non-blocking position, the latch arm is away from and not in contact with the retaining pin of the chassis; and a lock arm, pivotally coupled to the latch module chassis, wherein the lock arm is configured to engage with the button carriage, thereby preventing the button carriage from leaving the extended position, when the lock arm is not actuated by the retaining pin. - View Dependent Claims (13)

14. A latch module, for connecting to a retaining pin of a chassis, comprising:
-
a button carriage comprising a user-operable button, wherein the button carriage is slidably coupled to a latch module chassis of the latch module, thereby enabling the button carriage to move between an extended and a depressed position with respect to the latch module chassis, and wherein the button carriage, when the button is depressed a first time, moves from the extended position to the depressed position; an inverter arm, wherein the inverter arm is pivotally coupled to the latch module chassis, wherein the inverter arm is mechanically linked to the button carriage at a first end of the inverter arm, and wherein the button carriage, moving from the extended position to the depressed position, as the button is depressed, causes the inverter arm to pivot; a latch arm, mechanically linked to a second end of the inverter arm, wherein the latch arm is slidably coupled to the latch module chassis, wherein pivoting of the inverter arm causes the latch arm to slide from a non-blocking position into a blocking position, wherein, in the blocking position, the latch arm extends toward and makes contact with the retaining pin of the chassis, and wherein, in the non-blocking position, the latch arm is away from and not in contact with the retaining pin of the chassis; and a track arm, pivotally coupled to the latch chassis, wherein the track arm comprises a track that defines a trajectory of the latch arm between the non-blocking and blocking positions of the latch arm, when the track arm is in an operating position. - View Dependent Claims (15, 16)
