Abstract
Abstract This disclosure describes improvements in transit/combination case design. The transit/combination case cover latches are mounted in angled recesses on each of the four sides of the case cover to permit easy removal thereof from the front when stacked with other cases. Novel arrangements of cover latching mechanisms which are multi-functional to provide a hinging capability are disclosed which are operable in the angled recesses of the cover. Multi-functional case body reinforcement and stacking facilities are included in the form of complementary elongated raised portions and depressions in the top and underside of the case body respectively, which serve the double utility on the inner surface of the case bottom of being slides, or of providing bases therefore, to facilitate easy removal of the case contents. Provision is also made for pivotable cover latch mechanisms which provide the additional function of intercase latching when in the stacked mode. In a preferred embodiment of latch mechanism having hinging capability and ''''round-the-corner'''' operation required from the mounting thereof in the angled recesses of the case cover, the latch hook is utilized as the tension member of the pivot arrangement, while the compression member of the pivot arrangement forms an integral part of the latch itself.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
97 words
A transit/combination case comprising: a. a case body; b. a front cover removably attached to said body; c. at least one angled recess at a predetermined position on said front cover such that the recess on each cover in a stack of similar cases will align to provide a combined recess area; and d. latching means mounted within said recess for attaching said cover to said body whereby access to said latching means is provided by the combined recess area allowing for removal of said front cover from said body without removing the case from the stack.
Claim 2
Dependent Claim
97 words
A transit/combination case comprising: a. a case body; b. a front cover removably attached to said body; c. at least one angled recess at a predetermined position on said front cover such that the recess on each cover in a stack of similar cases will align to provide a combined recess area; and d. latching means mounted within said recess for attaching said cover to said body whereby access to said latching means is provided by the combined recess area allowing for removal of said front cover from said body without removing the case from the stack.
Claim 3
Dependent Claim
34 words
A transit/combination case according to claim 1 wherein the front cover further comprises: a. a face portion; b. a pair of opposing top and bottom portions; and c. a pair of opposing side portions.
Claim 4
Dependent Claim
21 words
A transit/combination case according to claim 2 wherein the top and bottom portions each contain a pair of angled recesses therein.
Claim 5
Dependent Claim
22 words
A transit/combination case according to claim 3 wherein each pair of said top and bottom portion angled recesses contain a latch mechanism.
Claim 6
Dependent Claim
19 words
A transit/combination case according to claim 2 wherein the said side portions each contain a pair of angled recesses.
Claim 7
Dependent Claim
19 words
A transit/combination case according to claim 5 wherein each pair of side portion angled recesses contain a latch mechanism.
Claim 8
Dependent Claim
47 words
The transit/combination case of claim 6 wherein the height of said male members is predetermined with respect to the depth of said female members to result in a predetermined gap between two abutting cases in a stack to allow for ease in case removal from the stack.
Claim 9
Dependent Claim
54 words
A transit/combination case according to claim 1 wherein said latching means comprises: a. a latch fixedly attached to said case cover, with one end hingedly attached to said body; and b. a latch strike fixedly attached to said case body for receiving said latch hook to secure said front cover to said case body.
Claim 10
Dependent Claim
67 words
The transit/combination case of claim 1 further comrising a plurality of male protruding members on the top surface of said case body, and a plurality of female recesses on the bottom surface of said case body in a one-to-one correspondence so that the female members of a top case will intermate with the corresponding male members of a bottom case in a stack thereby providing intercase support.
Claim 11
Dependent Claim
114 words
The transit/combination case according to claim 1 further comprising: a. at least one first L-shaped intercase latching member containing an aperture on a raised section thereof fixedly attached to a predetermined position at the bottom of said case body; and b. at least one second L-shaped intercase latching member containing a pair of raised sections thereon, with a latching member intermediate said raised sections fixedly attached to the top of said case body in a predetermined position so that the first L-shaped member of one case will align and intermate with the second L-shaped member of an abutting case in a stack allowing said latching means to contact the aperture of said first member.
Claim 12
Dependent Claim
129 words
The transit/combination case according to claim 10 wherein said first member is a metallic piece having a broad L-shaped raised portion with an aperture in one leg thereof serving as a latching strike and wherein the second member is a metallic piece having a pair of L-shaped parallel raised portions, recessing a latch mechanism mounted therebetween on one leg and providing a stacking recess therebetween on the other leg of said L-shaped second member, the latter being of complementary design with and serving as a receptacle for said stacking portion of said first member arranged on the adjacent case in a stack, and said latch mEchanism of said second member being arranged to engage with said strike of said first member provided on the adjacent case in the stack.
Claim 13
Dependent Claim
34 words
The transit/combination case according to claim 11 wherein the recessed latch mechanism from said second member is multi-functional and arranged to be pivotable to a secondary position for engaging and securing the case cover.
Claim 14
Dependent Claim
26 words
The transit/combination case according to claim 12 wherein the multi-functional latch mechanism is provided with means for storing the latch hook in a non-protruding storage position.
Claim 15
Dependent Claim
62 words
The transit/combination case according to claim 11 whereinsaid intercase stacking and latching arrangement further includes a bent rectangular metallic loop captivated between said second member and the case body within said parallel raised portions, said loop being exposed on one end between said parallel raised portions for providing a stop and preventing lateral displacement of said first member in the stacked mode.
Claim 16
Dependent Claim
41 words
The transit/combination case according to claim 14 wherein said loop is exposed between said parallel raised portions at the other ends thereof for providing a means for lashing together the cases in the stacked mode and for tying down the stack.
Claim 17
Dependent Claim
44 words
The transit/combination case according to claim 15 wherein said parallel raised portions of said second member are arranged to cooperate with said raised portions of said second member of the adjacent case in a stack to prevent a front-to-back shifting between the respective cases.
