2. Description of the Prior Art
Racks are widely used nowadays. Many of them are used to computer servers for organizing everything in a limited space. Therefore, the rack must have sliding rails corresponding in number to the computer servers for doing maintenance, replacement or any other services easily.
A number of related techniques have been published and patented, such as U.S. Pat. No. 6,181,549, U.S. Pat. No. 6,398,041, and U.S. Pat. No. 6,883,884.
U.S. Pat. No. 6,181,549 to Mills et al, titled “Chassis retaining system for an electronics rack”, disclosed a panel of a chassis provided with a handle, a securing device with a retaining surface, and a user interface device connected to the handle and the retaining device to secure the rack in place by means of the retaining surface. The securing device is coupled to the handle, and the retaining surface is movable with respect to the handle. The handle is mounted to the panel of the chassis, which must align with the rack. It is required to use a specific type of handle. When pushing the chassis back into the rack, the retaining surface of the handle will be used to secure the chassis. This design requires the handle in a specific type and at a specific position of the chassis.
U.S. Pat. No. 6,398,041 to Abbott, titled “Snap system for retaining slide mounted rack system into multiple racks without tools”, disclosed a pair of protuberances at respective ends of a slide assembly to be inserted into holes of support posts of a rack to be secured thereat. The slide assembly comprises a pair of rails to be connected with an enclosure or a chassis. The enclosure or chassis also connects to a pair of snaps corresponding to the support posts of the rack. When pushing the enclosure or chassis back into the rack, if a user would like to have the enclosure or chassis secured on the rack, the snaps are used to engage with the support posts of the rack.
U.S. Pat. No. 6,883,884 to Chen et al, title “Latch assembly for a track device”, disclosed a slide assembly composed of a first track member and a second track member. The first track member is slidable with respect to the second track member. The first track member comprises a latch assembly at one end thereof. The second track member comprises a latch seat for the latch assembly to be locked therein. The latch seat may be mounted on a wall for the latch assembly to be locked therein. The aforesaid patents did not mention direct engagement or disengagement of the slide assembly with respect to the rack when pushing the chassis or enclosure back into the rack.
