Protection device for expansion device of portable computer

Claim 2

A protection device for the expansion assembly of a portable computer in which the assembly includes a circuit board disposed in a casing having a window facing an entrance of an expansion socket within the circuit board, the device comprising a support assembly for disposition on a periphery of the window, a connecting member disposed in the support assembly for sliding movement between the socket entrance and the window, the connecting member including a first end and a second end, a restriction member connected to the first end for restricting the sliding movement of the connecting member, a stopper member connected to the second end, the distance between the stopper member and the restriction member being greater than the width of the socket entrance, a locating member connected to the second end of the connecting member, wherein when the connecting member is slid to move the stopper member toward the socket entrance and shield a part of the socket entrance, the restriction member prevents the connecting member from further sliding movement in order to protect the expansion socket from improper use.

Claim 3

The protection device of claim 1 wherein the locating member is connected to the stopper member for sliding movement between two locating holes formed in the casing.

Claim 4

The protection device of claim 2 wherein the locating member includes a resilient plate provided with a protuberance.

Claim 5

The protection device of claim 1 wherein the support assembly includes a driving member extending from the connecting member for extending through a slide slot formed in the casing and disposed parallel to the sliding direction of the connecting member.

Claim 6

The protection device of claim 1 wherein the support assembly includes a slit disposed parallel to the sliding direction of the connecting member, the connecting member further including a projecting plate extending from a top section of the stopper member and slidably engaged within the slit.

Claim 7

The protection device of claim 1 wherein the support assembly includes a support for disposition on a lower edge of the window for supporting the connecting member.

Claim 8

The protection device of claim 1 wherein the support assembly includes a frame within which the connecting member is installed.

Claim 9

The protection device of claim 1 wherein the restriction device includes a lock hole.

Claim 10

The protection device of claim 8 further including a through hole formed in the casing and corresponding to the lock hole, the through hole extending to the outer face of the casing, a locating socket formed in the outer face of the casing, whereby when the connecting member is slid to dispose the stopper member toward the socket entrance to shield a portion thereof, the lock hole is disposed immediately adjacent to and aligned with the through hole to form an elongated passage.

Claim 11

The protection device of claim 8 wherein the lock hole extends to an outer side of the casing, the casing being disposed in a base seat, an outer side wall of the base seat being formed with a locating socket aligned with the lock hole, the locating socket including a central through hole passing from the outer side wall of the base seat to the inner side wall thereof, whereby when the connecting member is slid and the stopper member is moved toward the socket entrance to shield a part thereof, the lock hole is disposed adjacent to and aligned with the through hole to form an elongated passage.

Claim 12

The protection device of claim 9 further including a lock device having a lock head insertable in the locating socket and a lock core disposable at the axis of the lock head, the lock core protruding out of the lock head and having an outwardly extending lock lever corresponding to the elongated passage.

Claim 13

A protection device for the expansion assembly of a portable computer, wherein the assembly includes a circuit board disposed within a casing having a window, the circuit board having first and second expansion sockets and the window facing an entrance of each expansion socket, the device comprising a support assembly for disposition on a periphery of the window, a first connecting member and a second connecting member disposed in the support assembly for sliding movement between the first and second socket entrances and the window, each connecting member including a first end and a second end, a restriction member connected to the first end of the first connecting member for restricting the sliding movement of both connecting members, a first stopper member connected to the second end of the first connecting member and the first end of the second connecting member, a second stopper member connected to the second end of the second connecting member, the distance between the first and second stopper members being greater than the width of the second socket entrance, a locating member connected to the second end of the second connecting member, whereby when the first and second connecting members are slid, the first and second stopper members are moved toward the first and second socket entrances to shield respective parts thereof, and the restriction member secures and prevents the first and second connecting members from further sliding to protect the first and second expansion sockets from being improperly used.

Claim 14

A protection device for the expansion assembly of a portable computer, wherein the assembly includes a circuit board disposed within a casing having a window, the circuit board having first and second expansion sockets and the window facing an entrance of each expansion socket, the device comprising a support assembly for disposition on a periphery of the window, a first connecting member and a second connecting member disposed in the support assembly for sliding movement between the first and second socket entrances and the window, each connecting member including a first end and a second end, a restriction member connected to the first end of the first connecting member for restricting the sliding movement of both connecting members, a first stopper member connected to the second end of the first connecting member and the first end of the second connecting member, a second stopper member connected to the second end of the second connecting member, the distance between the first and second stopper members being greater than the width of the second socket entrance, a locating member connected to the second end of the second connecting member, whereby when the first and second connecting members are slid, the first and second stopper members are moved toward the first and second socket entrances to shield respective parts thereof, and the restriction member secures and prevents the first and second connecting members from further sliding to protect the first and second expansion sockets from being improperly used.
