Abstract

The present invention is a system for direct docking of a storage device/carrier to a back plane of a support frame. The system includes a storage device/carrier including guidance tracks. Guidance rails are connected to the support frame, engage the guidance tracks respectively and guide and support the storage device/carrier into a mating engagement with a connector on a backplane of the support frame. Each guidance rail includes at least one spring element which raises the storage device/carrier away from the support frame as it is inserted thereinto. Further, the storage device/carrier includes opposed, outwardly extending spring elements which bear against the support frame. In operation, the opposed spring elements on the storage device/carrier are compressed as the storage device/carrier is inserted onto the guidance rails and bias the storage device/carrier against the support frame. As the storage device carrier engages with a connector, a reduced cross section region of the guidance tracks engage the sides of the guidance rails, thereby reducing slack between the guidance tracks and the guidance rails.

Claims

1. A system for direct docking of a storage device/carrier to a back plane of a support frame, the system comprising:

(a) a storage device/carrier;

(b) guidance tracks connectable to one of said support frame and said storage device/carrier; and

(c) guidance rails, connectable to another of said support frame and said storage device and adapted to engage said guidance tracks, respectively, for guiding and supporting said storage device/carrier into mating engagement with a mating connector on said back plane of said support frame, each of said guidance rails including at least one spring element extending from a surface thereof which is positioned to bear against an adjoining guidance track;

(d) spring means mounted on said storage device/carrier and in opposition to said spring elements, said spring means caused by action of said spring elements to be compressed and to bear against said support frame upon installation of said storage device/carrier into said support frame so as to restrain said storage device/carrier from movement in a direction orthogonal to mating surfaces of said guidance rails and guidance tracks.

2. The system of claim 1, wherein each said guidance track is divided into at least two segments, a first said segment being positioned to initially receive a mating guidance rail and having internal dimensions which enable movement of said guidance rail parallel to said mating surfaces.

3. The system of claim 2, wherein each said guidance rail includes a nose section which manifests a reduced cross section from a remainder of said guidance rail and a second said segment of said guidance track includes a reduced cross-section segment which, when mated with said nose section restrains movement of said guidance rail in a plane parallel to said mating surfaces of said guidance rail and said guidance track.

4. The system of claim 1, wherein each guidance track includes peripheral walls which act to restrain a guidance rail upon insertion of said guidance rail thereinto.

5. The system of claim 3, further comprising:

latch means for automatically locking said storage device/carrier in said support frame.
