Latch apparatus

Abstract

A latch apparatus includes a holder, a locking member capable of being received in the holder and a driving member connecting to the locking member. The holder includes an accessing hole in one of the sidewalls thereof. The locking member includes a locking portion and is movably placed between a first position and a second position. When the locking member moves to the first position, the locking portion extends out of the holder via the holder accessing hole. When the locking member moves to the second position, the locking portion is received in the holder. The driving member is capable of be manipulated to slide and cause the movement of the locking member from the first position to the second position.

1 . A latch apparatus comprising:
 a holder comprising a sidewall defining an accessing hole therein;   a locking member capable of being received in the holder, comprising a locking portion and movable between a first position and a second position, wherein in the first position, the locking portion extends out of the holder via the holder accessing hole, and in the second position, the locking portion is received in the holder; and   a driving member connecting to the locking member, and capable of be manipulated to slide and cause the movement of the locking member from the first position to the second position.   
   
   
       2 . The latch apparatus as claimed in  claim 1 , wherein the locking member is resiliently biased towards the first position. 
   
   
       3 . The latch apparatus as claimed in  claim 2 , further comprising a resilient member resiliently biasing the locking member towards the first position. 
   
   
       4 . The latch apparatus as claimed in  claim 3 , further comprising a support, wherein a first end of the support is capable of pivotably connected to the locking member and a second end of the support is pivotally engaged with the holder; the resilient member is a torque spring located near the second end of the support, a first arm of the resilient member is engaged with the support and a second arm of the resilient member fixed to the holder. 
   
   
       5 . The latch apparatus as claimed in  claim 1 , wherein the driving member further comprises a sliding slot defined in an end thereof, the locking member comprises a post pivotally and slidably received in the sliding slot. 
   
   
       6 . The latch apparatus as claimed in  claim 1 , wherein the holder further comprises at least one another wall defining a guiding slot therein, and a shaft fixed to the driving member, the shaft is slidably received in the guiding slot. 
   
   
       7 . The latch apparatus as claimed in  claim 6 , wherein the guiding slot comprises a sliding portion, a positioning portion and a neck portion formed between the sliding portion and the positioning portion. 
   
   
       8 . The latch apparatus as claimed in  claim 6 , wherein the driving member comprises at least one shoulder; the locking member comprises at least one tab protruding from a side thereof adapted to abut against the shoulder of the locking member. 
   
   
       9 . The latch apparatus as claimed in  claim 1 , further comprising a cover, wherein the holder comprises an opening configured to be covered by the cover. 
   
   
       10 . The latch apparatus as claimed in  claim 9 , wherein the cover comprises a claw and a pair of engaging teeth formed on opposite ends thereof; the holder further comprises a retaining portion and pair of detents capable of engaging with the cover claw and engaging teeth, respectively. 
   
   
       11 . The latch apparatus as claimed in  claim 9 , wherein the cover comprises at least one limiting portion extending therefrom, and configured to abut against the support. 
   
   
       12 . A functional module assembly adapted to be retained in a chassis defining a locking hole therein, the functional module assembly comprising:
 a functional module; and   a latch mechanism attached to the functional module and comprising:
 a locking member configured to be biased to engage with the chassis locking hole; and 
 a driving member connected to the locking member, and capable of be manipulated to slide with respect to the function module and enable the disengagement of the locking member from the chassis locking hole overcoming the biasing. 
   
   
   
       13 . The functional module assembly as claimed in  claim 12 , wherein the latching mechanism further comprises a holder configured to be fixed to the functional module and receive the locking member. 
   
   
       14 . The functional module assembly as claimed in  claim 13 , wherein the latching mechanism further comprises a torque spring received in the holder, and adapted to bias the locking member to extend out of the holder and engage with the chassis locking hole. 
   
   
       15 . The functional module assembly as claimed in  claim 13 , wherein the locking member is pivotally connected to the driving member, and the locking member is capable of being pivoted to disengage from the chassis locking hole when the driving member slides.
