Crimp-on clamp for flexible duct

Claim 2

In a flexible ducting having a convoluted wire supporting a flexible material, a clamp at at least one end of said ducting, comprising, an over-center toggle clamp, a deformable receptacle secured to each end of said clamp, one receptacle receiving a free end of said convoluted wire, the other receptacle being clamped about the endmost convolution of the wire in said hose.

Claim 3

A ducting as in claim 1 in which said one receptacle comprises a tubular socket, said wire end extending into said socket, said socket and wire end being crimped to retain said wire in said socket.

Claim 4

A ducting as in claim 1 in which said other receptacle comprises a V-shaped sheet metal element forming a pair of jaws, said jaws being disposed around said wire and crimped thereto.

Claim 5

In a flexible ducting having a convoluted wire supporting a flexible material, a clamp at at least one end of said ducting, comprising, a tubular socket receiving a free end of said wire and being crimped thereto, said socket having an integral extension, a link having one end pivotally secured to said extension, a V-shaped metallic connector crimped about an endmost convolution of said wire adajcent said link, said connector having an integral extension pivotally secured to said link, said link and extensions being configurated to provide an over-center toggle clamp.

Claim 6

In a flexible ducting having a convoluted wire supporting a flexible material, a clamp at at least one end of said ducting, comprising, a tubular socket receiving a free end of said wire and being crimped thereto, said socket having an integral extension, a link having one end pivotally secured to said extension, a V-shaped metallic connector crimped about an endmost convolution of said wire adajcent said link, said connector having an integral extension pivotally secured to said link, said link and extensions being configurated to provide an over-center toggle clamp.

Claim 7

A ducting as in claim 4 in which said connector extension has an arcuate portion projecting away from said ducting, said socket extension having a cavity overlying said projecting section when said socket extension is in clamping position.

Claim 8

A ducting as in claim 5 wherein said flexible material is laminated about said wire, the free end of said wire being stripped of said flexible material and inserted into said tubular socket, said V-shaped connector being crimped about said flexible material and portion of the wire which the flexible material surrounds.

Claim 9

In a flexible ducting having a convoluted wire supporting a flexible material, a toggle clamp at at least one end of said ducting, comprising, a center link, a movable link consisting of a strap pivotally connected at one end to one end of said center link, the other end of said strap having a socket receiving and crimped to a free end of said wire, a fixed link consisting of an L-shaped strap having one end pivoted to the other end of said center link, said L-shaped strap having a leg folded upon the strap to form a V-shaped connector, said connector being positioned over an adjacent convolution and crimped thereto.

Claim 10

In a flexible ducting having a convoluted wire supporting a flexible material, a toggle clamp at at least one end of said ducting, comprising, a center link, a movable link consisting of a strap pivotally connected at one end to one end of said center link, the other end of said strap having a socket receiving and crimped to a free end of said wire, a fixed link consisting of an L-shaped strap having one end pivoted to the other end of said center link, said L-shaped strap having a leg folded upon the strap to form a V-shaped connector, said connector being positioned over an adjacent convolution and crimped thereto.

Claim 11

Ducting as in claim 7 in which said connector crimp is a V formed intermediate the ends of said connector, the remaining portions of said connector on each side of said V being in substantial alignment.

Claim 12

Ducting as in claim 7 in which said fixed clamp has an arcuate portion extending from said connector to said pivotal connection to said center link projecting said pivotal connection radially outwardly of said ducting, said arcuate portion having a longitudinal stiffening crown.

Claim 13

Ducting as in claim 9 in which the strap of said movable link has an outwardly projecting bow intermediate its ends overlying said outwardly projecting pivotal connection, said bow having a longitudinal stiffening crown.
