Abstract

A computer enclosure includes a chassis (90), a cover (10) and a resilient member (50). The chassis includes a recess (911) and at least one locking member (70). A cover is mounted on the chassis. The cover has a stop (115) adapted to engage with the locking member for securing the cover on the chassis. The resilient member is attached to the cover and compressed in the recess for forcing the cover to move away from the chassis when the locking member is disengaged from the stop.

Claims

1. A computer enclosure comprising:

a chassis comprising a side wall, the side wall defining a first opening and a third opening, a locking member secured on an inner side of the side wall, the locking member comprising an elastic finger, the elastic finger comprising a second hook extending through the first opening from the inner side of the side wall to protrude out of an outer side of the side wall, the locking member further comprising an protrusion extending through the first opening from the inner side of the side wall to protrude out of the outer side of the side wall;

a cover adapted to be mounted on the chassis, the cover comprising a side panel facing the outside of the side wall of the chassis, the side panel forming a stop configured to slide over the second hook and bend the elastic finger to engage with the second hook; and

a pressing member mounted on the side panel of the cover with one free end of the pressing member secured on the side panel and the other free end adapted to swing on the side panel, the other free end of the pressing member being aligned with the protrusion configured to push the protrusion to bend the elastic finger to disengage the second hook from the stop.

2. The computer enclosure as described in claim 1, wherein the pressing member is mounted on an inner side of the side panel, the side panel defines a hole in alignment with the other free end of the pressing member to access the other free end of the pressing member.

3. The computer enclosure as described in claim 1, wherein a resilient member is attached to the cover, the resilient member comprising a spring and a fixing portion, the fixing portion is secured on the cover to attach the resilient member on the cover, and the spring is compressed between the cover and the chassis configured to move the cover away from the chassis when the second hook is disengaged from the stop.

4. The computer enclosure as described in claim 1, wherein a plurality of tabs is formed on the chassis for retaining the locking member thereon.

5. The computer enclosure as described in claim 1, wherein the chassis has a plurality of slits, and the cover has a plurality of latching pieces for engaging into the slits.

6. The computer enclosure as described in claim 1, wherein the locking member comprises a pair of wings secured on the side wall, the elastic finger is formed between the pair of wings, the second hook is formed on one end of the elastic finger, and the locking member further comprises a connecting portion connecting the other end of the elastic finger and the two wings together adapted to bend the one end of the elastic finger around the connecting portion.

7. A computer enclosure comprising:

a chassis comprising at least one locking member, the locking member comprising a pair of wings, an elastic finger formed between the pair of wings, and a connecting portion connecting an end of the elastic finger and the two wings together adapted to bend the other end of elastic finger around the connecting portion, the pair of wings firmly secured on the chassis, the other end of the elastic finger forming a second hook thereon;

a cover adapted to be mounted on the chassis, the cover having a stop, the stop configured to slide over the second hook and bend the elastic finger to engage with the second hook for securing the cover on the chassis; and

a resilient member compressed between the chassis and the cover for forcing the cover to move away from the chassis when the second hook is disengaged from the stop.

8. The computer enclosure as described in claim 7, wherein the chassis has a plurality of slits, and the cover has a plurality of latching pieces for engaging into the slits.

9. The computer enclosure as described in claim 7, wherein the resilient member comprising a spring and a fixing portion, the fixing portion is secured on the cover to attach the resilient member on the cover, and the spring is compressed between the cover and the chassis.

10. The computer enclosure as described in claim 7, wherein the chassis comprises a side wall, the side wall defines a third opening, the locking member is secured on an inner side of the side wall with the second hook extending through the first opening from the inner side of the side wall to protrude out of an outer side of the side wall.

11. The computer enclosure as described in claim 10, wherein the cover comprises a side panel facing the outside of the side wall of the chassis, the stop is formed on the side panel.

12. The computer enclosure as described in claim 7, wherein the chassis comprises a side wall, the locking member is secured on an inner side of the side wall, the sidewall defines a first opening, the locking member further comprises a protrusion extending through the first opening from the inner side of the side wall to protrude out of the outer side of the side wall, a pressing member is mounted on the cover with one free end of the pressing member secured on the cover and the other free end adapted to swing on the cover, the other free end of the pressing member is aligned with the protrusion and configured to push the protrusion to bend the elastic finger to disengage the second hook from the stop.

13. The computer enclosure as described in claim 12, wherein the pressing member is mounted on an inner side of the cover, the cover defines a hole in alignment with the other free end of the pressing member to access the other free end of the pressing member.

14. A computer enclosure comprising:

a chassis comprising a side wall with at least one opening defined, a plurality of tabs being formed on an inner surface of the side wall;

a cover mounted on the chassis, the cover having a stop formed on an inner surface of the cover; and

a locking member retained on the inner surface of the side wall of the chassis by the plurality of tabs, the locking member having at least one resilient hook extending through the opening in the side wall of the chassis and engaging with the stop of the cover;

whereby when the hook of the locking member is deformed into the opening of the chassis, the cover is ready to be removed wherein a pressing member for deforming the hook of the locking member is attached to the cover, and the pressing member is accessible outside.

15. The computer enclosure as described in claim 14, wherein a resilient member is compressed between the chassis and the cover for forcing the cover to move away from the chassis.

16. The computer enclosure as described in claim 15, wherein the chassis defines a recess at a front corner thereof for receiving the resilient member.

17. The computer enclosure as described in claim 16, wherein one end of the resilient member is secured on the cover, and the other end of the resilient member is compressed against a wall of the recess.
