Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
130 words
A latching device for latching a drawer to a drawer slide having a notch in its upper surface, comprising a rail having a horizontal web formed with a slot, and an upstanding flange along one edge, connection points on the flange for connecting the flange to the side of the drawer, and a one-piece resilient plastic catch having a relatively inflexible body snap-coupled to co-operating snap-coupling attachment means on the web, a relatively flexible neck molded integrally with the body, and a relatively inflexible head molded integrally with the neck and normally passing through the slot in the web for engagement with the notch in the slide and being pivotable upwardly by flexure of the neck relative to the body to release the engagement of the head with said notch.
Claim 2
Dependent Claim
130 words
A latching device for latching a drawer to a drawer slide having a notch in its upper surface, comprising a rail having a horizontal web formed with a slot, and an upstanding flange along one edge, connection points on the flange for connecting the flange to the side of the drawer, and a one-piece resilient plastic catch having a relatively inflexible body snap-coupled to co-operating snap-coupling attachment means on the web, a relatively flexible neck molded integrally with the body, and a relatively inflexible head molded integrally with the neck and normally passing through the slot in the web for engagement with the notch in the slide and being pivotable upwardly by flexure of the neck relative to the body to release the engagement of the head with said notch.
Claim 3
Dependent Claim
24 words
A device as claimed in claim 1 in which the neck has a relatively thin cross-section as compared with the head and the body.
Claim 4
Dependent Claim
78 words
A device as claimed in claim 1 in which one of the body and web carries a projecting abutment and the other has a recess co-operating with the abutment to retain the body against movement laterally of the web, and one of the body and the web carries a laterally projecting retaining member and the other has a laterally projecting engagement member co-operating with the retaining member to retain the body against movement upwardly away from the web.
Claim 5
Dependent Claim
39 words
A device as claimed in claim 3 in which the retaining member and engagement member bias the adjacent portion of the body resiliently downwards toward the web whereby the abutment and recess are biased into engagement with one another.
Claim 6
Dependent Claim
94 words
A device as claimed in claim 1 in which the body has an integrally molded stub and an integrally molded hook on its lower side, the hook defining a recess facing toward the head, and the coupling attachment means on the web comprise a hole snugly receiving the stub and a tab bent upwardly from the web with a free end facing away from the slot and received in said recess, the tab biasing the portion of the body carrying the hook resiliently downward toward the web relative to the portion carrying the stub.
Claim 7
Dependent Claim
34 words
A device as claimed in claim 5 in which the stub is formed adjacent the end of the body remote from the head and the hook is spaced between the stub and the neck.
Claim 8
Dependent Claim
25 words
A device as claimed in claim 6 in which the underside of the body is formed with an indentation between the hook and the tab.
Claim 9
Dependent Claim
34 words
A device as claimed in claim 1 having a projection with a downwardly and outwardly sloping upper surface on the flange of the rail engaging the upper side of the body adjacent the neck.
Claim 10
Dependent Claim
48 words
A device as claimed in claim 1 having a tab bent inwardly from the side of the flange of the rail, the lower surface of the tab engaging the upper side of the body adjacent the neck, and the upper surface of the tab sloping downwardly and outwardly.
Claim 11
Dependent Claim
24 words
A device as claimed in claim 9 in which said tab overlies the part of the body having the hook formed on its underside.
Claim 12
Dependent Claim
24 words
A device as claimed in claim 9 in which the tab is formed by an approximately semi-circular portion of the wall of the flange.
Claim 13
Dependent Claim
26 words
A device as claimed in claim 1 in which the upper side of the body is smoothly convexly curved at the end remote from the head.
Claim 14
Dependent Claim
30 words
A device as claimed in claim 1 in which a side of the head facing toward the body engages or is closely adjacent to the adjacent side of the slot.
Claim 15
Dependent Claim
20 words
A device as claimed in claim 13 in which in the normal position said side inclines downwardly toward the body.
Claim 16
Dependent Claim
26 words
A device as claimed in claim 1 in which the head portion includes a downward projection engaging the upper side of the web adjacent the slot.
Claim 17
Dependent Claim
26 words
A device as claimed in claim 15 in which the projection is formed between a portion of the head passing through the slot and the body.
Claim 18
Dependent Claim
23 words
A device as claimed in claim 1 in which the upper side of the head is formed with a laterally projecting edge portion.
Claim 19
Dependent Claim
23 words
A device as claimed in claim 17 in which the edge portion projects from the end of the head remote from the body.
Claim 20
Dependent Claim
39 words
A device as claimed in claim 5 wherein the rail is symmetrical about a transverse median line and the web portion of the rail is formed adjacent each of its ends with said tab and said hole and slot.
