Boot and detachable extension therefor

Claim 2

A boot and a detachable extension therefor comprising a boot of flexible waterproof material having a connecting element adjacent its upper end formed integrally therewith, and an extension of flexible waterproof material having a cooperating connecting element at one end thereof formed integrally therewith and forming with said first connecting element a substantially leakproof joint, and a clamping element formed integrally with said boot and adapted to be resiliently applied over said joint to prevent leakage therethrough.

Claim 3

A boot and extension as defined in claim 1 wherein the clamping element is carried by the free end of a flexible tubular portion, the fixed end of the tubular portion being connected to the inside of the boot.

Claim 4

A boot having a connecting element for cooperation with an extension, and a clamping element formed integrally with said boot and adapted to be applied to said connecting element to conceal and protect the same when the extension is not in use.

Claim 5

A boot having a connecting element for cooperation with an extension, and a clamping element formed integrally with said boot and adapted to be applied to said connecting element to conceal and protect the same when the extension is not in use.

Claim 6

A boot and a detachable extension therefor comprising a boot of flexible waterproof material having a connecting element comprising a T-shaped ring formed integrally therewith, a tubular extension of flexible waterproof material having an annular slotted member formed integrally therewith and adapted to receive said ring to provide a connecting joint, and a clamping element Formed integrally with said boot and applied over said joint to render the same substantially waterproof.

Claim 7

A boot and a detachable extension therefor comprising a boot of flexible waterproof material having a connecting element comprising a T-shaped ring formed integrally therewith, a tubular extension of flexible waterproof material having an annular slotted member formed integrally therewith and adapted to receive said ring to provide a connecting joint, and a clamping element Formed integrally with said boot and applied over said joint to render the same substantially waterproof.

Claim 8

A boot and extension as defined in claim 4 wherein the lower portion of said tubular sleeve is folded down over said joint prior to applying the clamping element whereby the entire joint is concealed by said extension upon drawing the latter upwardly.

Claim 9

A boot and a detachable extension therefor comprising in combination, a boot of flexible waterproof material, a detachable extension of flexible waterproof material, the upper portion of the boot having spaced connecting elements, and the lower portion of said extension also having correspondingly spaced cooperating connecting elements, the boot having an integral outwardly downturned tubular portion, having an upturned lip and the extension having an inwardly upturned turned portion, the spaced connecting elements of the extension turned upwardly and cooperating with the correspondingly spaced connecting elements of the boot between the downturned tubular boot extension and the boot and the upturned lip cooperating with a connecting element on the extension.

Claim 10

A boot and a detachable extension therefor comprising in combination, a boot of flexible waterproof material, a detachable extension of flexible waterproof material, the upper portion of the boot having spaced connecting elements, and the lower portion of said extension also having correspondingly spaced cooperating connecting elements, the boot having an integral outwardly downturned tubular portion, having an upturned lip and the extension having an inwardly upturned turned portion, the spaced connecting elements of the extension turned upwardly and cooperating with the correspondingly spaced connecting elements of the boot between the downturned tubular boot extension and the boot and the upturned lip cooperating with a connecting element on the extension.

Claim 11

A boot and extension as defined in claim 6 wherein the free end of said inwardly upturned tubular portion of the extension is provided with a circular connecting element triangular in cross section for cooperation with a similar connecting element formed integrally with the upper end of said tubular downturned portion of the boot, the free end of said downturned tubular portion having a circular band L-shaped in cross section for cooperation with an oppositely directed similar band formed on said upturned portion providing an L-shaped joint.

Claim 12

A boot and extension as defined in claim 7 wherein a second circular band L-shaped in cross section disposed at the lower end of said upturned portion of the extension cooperates with an oppositely directed similar band formed on the boot providing a second L-shaped joint.

Claim 13

A boot as defined in claim 8 wherein the L-shaped circular connecting element formed at the free end of said downturned tubular portion is adapted to engage with the L-shaped connecting element formed on the boot when the extension is not in use.

Claim 14

A boot and extension as defined in claim 8 wherein said upturned portion is provided at its lower end with a projection adapted to engage said first L-shaped joint to hold the same frictionally tight upon pulling the extension upwardly.

Claim 15

A boot and extension as defined in claim 10 wherein the boot is provided with a plurality of circular projections adapted for overlapping engagement with similar projections extended from the upturned portion of said extension.
