Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A sectional carrying case capable of being interlocked with another sectional carrying case comprising dovetailed tongue and groove formations on at least one side of the carrying case to permit it to be interlocked with complementary dovetailed tongue and groove formations of another sectional carrying case, at least one of the groove formations of the sectional carrying case having an open end, a guide slot in a side of the sectional carrying case having the tongue and groove formations, a slide interlocked with and accommodated for movement within said guide slot, an extension formed integrally with said slide to permit actuation of the slide, and a releasable lock formed integrally with the slide and movable from a release position adjacent the end of one of the tongues to a locked position partially across the open end of said open-ended groove formation to prevent relative movement of the sectional carrying case with an adjacent carrying case with which it is interlocked.
Claim 2
Dependent Claim
160 words
A sectional carrying case capable of being interlocked with another sectional carrying case comprising dovetailed tongue and groove formations on at least one side of the carrying case to permit it to be interlocked with complementary dovetailed tongue and groove formations of another sectional carrying case, at least one of the groove formations of the sectional carrying case having an open end, a guide slot in a side of the sectional carrying case having the tongue and groove formations, a slide interlocked with and accommodated for movement within said guide slot, an extension formed integrally with said slide to permit actuation of the slide, and a releasable lock formed integrally with the slide and movable from a release position adjacent the end of one of the tongues to a locked position partially across the open end of said open-ended groove formation to prevent relative movement of the sectional carrying case with an adjacent carrying case with which it is interlocked.
Claim 3
Dependent Claim
75 words
A sectional carrying case as set forth in claim 1 in which the guide slot is located in the region of a corner of the sectional carrying case and extends in a substantially vertical direction and including a vertically extending convex surface formed on the corner of the sectional carrying case and a complementary concave surface formed on a portion of the releasable lock to slidably engage the convexly curved surface of the carrying case.
Claim 4
Dependent Claim
59 words
A sectional carrying case as set forth in claim 1 including an outwardly extending flange at the upper edge of the sectional carrying case and a guide opening in said flange in which said actuating extension is guided to permit the upper end of the actuating extension to be finger depressed to move the releasable lock to locked position.
Claim 5
Dependent Claim
60 words
A sectional carrying case as set forth in claim 1 in which the releasable lock includes a locking surface which in the release position of the lock is in face-to-face engagement with the end of one of the tongue formations and in the locking position is movable to partially close the of open end of one of the groove formations.
Claim 6
Dependent Claim
34 words
A sectional carrying case as set forth in claim 4 including a dovetail notch which in the release position of the lock forms a continuation of the dovetail edge of the adjacent tongue formation.
