Abstract

A docking module facilitates conversion of a portable computer between a lap-top mode of operation and a desk-top mode of operation by permitting simultaneous attachment of the computer to a plurality of electrical connectors thereby eliminating the need for individual cable connections between the computer and the respective individual apparatus. Toggle latches that attach the docking module to the computer chassis contain spring biased latches designed to emit an audible signal indicating proper alignment between the complementary connectors on the facing surfaces of the docking module and the computer chassis, whereby toggling of the latches can be undertaken without danger of damaging the connectors.

Claims

1. A docking module apparatus for electrically joining a computer to one or more elements of ancillary support hardware, comprising:

a casing structure adapted for attachment to said computer having on one support surface a plurality of sets of complementary electrical connectors corresponding in number and location to mating sets of electrical connectors on a support surface on said computer, each connector having a plurality of mutually insulated contacts;

means for effecting alignment adjustment between said complementary sets of electrical connectors and said mating connectors;

manually operated toggle latch mechanisms for securing said apparatus to said computer and for completing the connection between the respective of said complementary electrical connectors and said mating connectors, said toggle latch mechanisms being disposed on opposite ends of said casing structure and having means thereon for grippingly engaging said computer; and

spring means for operating said computer engaging means and operative to impart an audible signal when said connectors are placed in accurate mutual alignment prior to the manual actuation of said toggle latch mechanisms.

2. Apparatus according to claim 1 including means on said compute forming a depression for engagement with said toggle latch mechanism, said toggle latch mechanism including a latch hook operatively engaged by said spring means and containing a projection for gripping engagement with said depression, said spring means exercising sufficient biasing force on said latch hook to effect emmision of an audible signal upon said projection entering said depression when said connectors are accurately mutually aligned.

3. Apparatus according to claim 2 wherein said depression is spaced from said computer support surface a distance within which to be engaged by said latch hook projection only when said connectors in each mating pair are placed in initial mutual engagement.

4. Apparatus according to claim 3 wherein said connectors in each mating pair include a pin-bearing male connector and a receptacle-bearing female connector and said depression can be engaged by said latch hook only upon receipt of all of the pins on all of said male connectors in the receptacles in said female connectors.

5. Apparatus according to claim 4 wherein said toggle latch mechanisms each include a toggle lever pivotally connected to said docking module casing, a latch hook pivotally connected to said toggle lever, and spring means operative to bias said toggle lever into both its unlatched and its latched positions.

6. Apparatus according to claim 5 wherein said toggle lever contains angularly disposed cam surfaces engageable with said spring means for biasing said toggle lever into its unlatched and latched positions.

7. Apparatus according to claim 6 wherein said spring means comprises a leaf spring having one end fixedly secured to said casing structure and its free end adapted to engage one or the other of said toggle lever cam surfaces.

8. Apparatus according to claim 6 wherein said leaf spring is a compound spring having free ends for biasing said toggle lever and said latch hook, respectively.

9. A docking module apparatus for joining a computer to one or more elements of ancillary support hardware, comprising:

a casing structure adapted for attachment to said computer having on one support surface a plurality of sets of complementary electrical connectors corresponding in number and location to mating sets of connectors on a support surface on said computer;

means for effecting alignment adjustment between said complementary sets of electrical connectors and said mating connectors;

manually operated toggle latch mechanisms for securing said apparatus to said computer and for completing the connection between the respective of said complementary electrical connectors and said mating connectors, said toggle latch mechanisms being disposed on opposite ends of said casing structure and having means thereon for grippingly engaging said computer; and

spring means for biasing said toggle latch mechanisms selectively into attaching or releasing relationship with said computer in response to alternate attaching and releasing manipulations of said toggle latch mechanisms.

10. Apparatus according to claim 9 wherein said attaching and releasing means includes means forming depressions in said computer and a latch hook having a projection surface associated with each toggle latch mechanism for grippingly engaging one edge of said depression upon manual actuation of an operating lever in one direction and a bearing surface facing oppositely from said projection surface for engagement with an oppositely facing second edge of said depression upon manual actuation of said operating lever in an opposite direction.

11. Apparatus according to claim 10 including cam and follower means cooperably disposed on said casing and said hook for urging said hook laterally outwardly from said depression under the influence of said operating lever.
