Abstract

In a computer logic package, it is sometimes desirable to have a small feature logic book 2 that is mechanically and electrically attached to a large logic book 1 (see Fig. 1). The large logic book establishes the interface to the remaining logic in the computer and physically supports the small book. These small books can be easily added to the large book by a simple latching device 3. A one-piece molded latch that performs the desired functions is herein described. The small book is inserted into the large book with the latch in the lower position. The latch is then lifted to engage the camming surfaces 4. As the latch is pivoted further, it will lock onto the rear surface of the small book.

Small Logic Book Latch

In a computer logic package, it is sometimes desirable to have a small feature logic book 2 that is mechanically and electrically attached to a large logic book 1 (see Fig. 1). The large logic book establishes the interface to the remaining logic in the computer and physically supports the small book. These small books can be easily added to the large book by a simple latching device 3. A one-piece molded latch that performs the desired functions is herein described. The small book is inserted into the large book with the latch in the lower position. The latch is then lifted to engage the camming surfaces 4. As the latch is pivoted further, it will lock onto the rear surface of the small book. To remove the small book, the latching member is squeezed to disengage the latch and then pivoted downward to cam the small book out of the large book.

The large book 1 has side surfaces that are designed with camming slots 4 for the small book latch 3. The side surfaces 5 provide the guiding entrance slot for the small books. The small book has the proper width enabling it to slide easily between the sides of the large book and still have the latch levers 3 engage the camming slots. The latch 3 has pivots on the small book that are used to give the proper action to engage the small book into the large book. The top of the latch has a pivoting member 7 with a retaining tip 8 that engages the rear surface of the small book through a mat...
