An ear projects outwardly between the apertures and an elongated slot in the overlapping portion. The lapped portion includes a plurality of openings, each having an outwardly projecting hook. The hooks and projections are geometrically shaped to, upon engagement with one another, laterally center the lapped and lapping portions and interlock the portions to one another. The lapped portion includes an outwardly projecting protuberance engageable in the slot of the lapping portion to guide the portions for longitudinal and laterally constrained movement. The ear has parallel sides and lobes projecting outwardly from the sides, forming a purchase for the jaws of a crimping tool, preventing the tool from slipping from the ear. Upon interlocking the hooks and projections, the ear is crimped to secure the clamp about the parts. | InventorAssigneeApplicationNo. 691021 filed on 08/05/1996US Classes:24/20CW, Circumferentially swagged band clamp24/20R, Metal bands24/20EEEnd-to-end integral band end connectionField of Search24/20CW, Circumferentially swagged band clamp24/20R, Metal bands24/19, With tighteners24/22, One piece24/20EE, End-to-end integral band end connection24/20W, Swedged to lock band ends24/23W, Swedged sheet metal band connection24/23EEEnd-to-end integral with band connecting meansExaminersPrimary: Sakran, Victor N.Attorney, Agent or FirmUS Patent ReferencesRe33639, 4299012, Hose clampIssued on: 11/10/1981 Inventor: Oetiker4492004, Earless clamp structure Issued on: 01/08/1985 Inventor: Oetiker4622720, Fastening arrangement for open hose clamp Issued on: 11/18/1986 Inventor: Oetiker4711001, Fastening arrangement for open hose clamp Issued on: 12/08/1987 Inventor: Oetiker4991266, Mechanical interlock for open clamp structures Issued on: 02/12/1991 Inventor: Oetiker5103535, Clamping band Issued on: 04/14/1992 Inventor: Ishijima5105509, Hose clamp Issued on: 04/21/1992 Inventor: Lilley5138746, Clamp structure Issued on: 08/18/1992 Inventor: Ojima, et al.5191684, Clamp structure Issued on: 03/09/1993 Inventor: Kenwright5305499, Hose clamp Issued on: 04/26/1994 Inventor: Oetiker5339496Self-aligning clamp structure Issued on: 08/23/1994 Inventor: Oetiker International ClassB65D 063/00 |
