Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
210 words
A fastening device for assembling together at least two modular casings in a side by side relationship, said fastening device comprising: a groove provided in a face of each of said casings, the groove of one casing being aligned with the groove of an adjacent casing to form a channel across said faces of said casings, each of said grooves having first engaging surfaces; a connecting slide slidably mounted in said groove for selective reciprocal movement in said channel between a fastened position and a disengaged position, said slide having a guide portion for guiding the slide in the groove and a second engaging surface at each end of said slide; one of the second engaging surfaces of said slide engaging one of the first engaging surfaces on the groove of one casing and another of the second engaging surfaces of said slide engaging another of the first engaging surfaces on the grooves of an adjacent casing in the fastened position of said slide, the distance between the second engaging surfaces on said slide corresponding to the distance between said first engaging surfaces on said one casing and said adjacent casing, the distance between said second engaging surfaces being no greater than the width of said face of said casing.
Claim 2
Dependent Claim
210 words
A fastening device for assembling together at least two modular casings in a side by side relationship, said fastening device comprising: a groove provided in a face of each of said casings, the groove of one casing being aligned with the groove of an adjacent casing to form a channel across said faces of said casings, each of said grooves having first engaging surfaces; a connecting slide slidably mounted in said groove for selective reciprocal movement in said channel between a fastened position and a disengaged position, said slide having a guide portion for guiding the slide in the groove and a second engaging surface at each end of said slide; one of the second engaging surfaces of said slide engaging one of the first engaging surfaces on the groove of one casing and another of the second engaging surfaces of said slide engaging another of the first engaging surfaces on the grooves of an adjacent casing in the fastened position of said slide, the distance between the second engaging surfaces on said slide corresponding to the distance between said first engaging surfaces on said one casing and said adjacent casing, the distance between said second engaging surfaces being no greater than the width of said face of said casing.
Claim 3
Dependent Claim
22 words
The fastening device of claim 1, wherein the slide is located completely on one face of a casing in the disengaged position.
Claim 4
Dependent Claim
28 words
The fastening device of claim 1, wherein the first engaging surface of said groove is a notch and the second engaging surface of said slide is a hook.
Claim 5
Dependent Claim
38 words
The fastening device of claim 3, wherein the groove of one casing includes two symmetrically positioned notches disposed in the bottom of said groove, the slide having two symmetrically positioned hooks for selectively engaging one of said notches.
Claim 6
Dependent Claim
14 words
The fastening device of claim 1, wherein the second engaging surfaces are elastically deformable.
Claim 7
Dependent Claim
66 words
The fastening device of claim 1 adapted for use on casings having two relatively narrow faces with terminals and two relatively large side faces, said groove extending above said terminals and across the entire width of said narrow face, the slide projecting beyond the plane of a large side face in the fastened position and being located between the large side faces in the disengaged position.
