Abstract

A hose or duct having and end with an adjustable clamp fixed in an enforced position thereon. The clamp includes a band which encircles the hose or duct. The band has an adjustable diameter operable to compress the hose or duct to form a fluid tight seal onto an exterior of a connection port. The adjustable clamp secured to the duct or hose by at least one mounting pad.

First claim

What is claimed is:

1. A positionally fixed clamp for a hose or duct, the positionally fixed clamp comprising:
an adjustable ring shaped clamp having a circumferential band having an adjustable diameter, the clamp adapted for mounting on an radially outer circumferential surface of a duct or hose to compressibly secure the duct or hose to a connection port or fitting;
a position fixing band having at least one T-shaped portion, including:
a head portion of the T-shaped portion, the head portion arranged on a radially inner surface or arranged on a radially outer surface of the circumferential band of the ring shaped clamp,
wherein the head portion engages with and positionally locks the position fixing band to the adjustable ring shaped clamp;
at least one position fixing leg, each leg formed by the at least one T-shaped portion of the position fixing band, the at least one position fixing leg projecting in a longitudinal direction outwardly from the head portion and the adjustable ring shaped clamp;

wherein the position fixing band is elongated on and conforms to an arcuate shape of the radially outer surface or the radially inner surface of the adjustable ring shaped clamp;
wherein the position fixing band is permanently secured onto the circumferential band of the clamp by spot welds or by rivets;
further comprising:
the hose or duct of a rubber or plastic material, the hose or duct having:
a connecting end for sealably connecting to a connection port or fitting;
a radially inner surface;
a radially outer circumferential surface;

wherein the adjustable ring shaped clamp is arranged on closing about an outer circumference of the hose or duct, the adjustable ring shaped clamp positioned at a fixed radial position on the outer circumferential surface and at a fixed longitudinal spacing from the connecting end;
a first mounting pad securely fixed onto the outer surface of the hose or duct, the first mounting pad securely fixed onto the at least one position fixing leg, fixing the rotational position and longitudinal spacing of the adjustable ring shaped clamp on the hose or duct.

2. The positionally fixed adjustable clamp according to claim 1 , further comprising:
a second mounting pad securely fixed onto the outer circumferential surface of the hose or duct, the second mounting pad securely fixed onto the adjustable ring shaped clamp, fixing the rotational position and longitudinal spacing adjustable ring shaped clamp on the hose or duct,
wherein the first mounting pad and the second mounting pad are spaced apart in a longitudinal direction and aligned longitudinally.

3. The positionally fixed adjustable clamp according to claim 2 , wherein
the first mounting pad, together with the hose or duct, surrounds and encapsulates a portion of the at least one position fixing leg; and
the second mounting pad extends in a longitudinal direction across and covers a radially outer portion of the adjustable ring shaped clamp.

4. The positionally fixed adjustable clamp according to claim 2 , wherein
the first and second mounting pads are rubber pads or plastic pads;
wherein the mounting pads are permanently secured to the hose or duct by vulcanization, or permanently welded onto the hose or duct.

5. A positionally fixed clamp for a hose or duct, the positionally fixed clamp comprising:
an adjustable ring shaped clamp having a circumferential band having an adjustable diameter, the clamp adapted for mounting on an radially outer circumferential surface of a duct or hose to compressibly secure the duct or hose to a connection port or fitting;
the circumferential band having at least one T-shaped portion, including:
at least one position fixing leg, each position fixing leg formed by the circumferential band, the at least one position fixing leg projecting in a longitudinal direction outwardly from the circumferential band;

further comprising:
the hose or duct of a rubber or plastic material, the hose or duct having:
a connecting end for sealably connecting to a connection port or fitting;
a radially inner surface;
a radially outer circumferential surface;

wherein the adjustable ring shaped clamp is arranged on and closing about an outer circumference of the hose or duct, the adjustable ring shaped clamp positioned at a fixed radial position on the outer circumferential surface and at a fixed longitudinal spacing from the connecting end;
a first mounting pad securely fixed onto the outer surface of the hose or duct, the first mounting pad securely fixed onto the at least one position fixing leg, fixing the rotational position and longitudinal spacing adjustable ring shaped clamp on the hose or duct;
a second mounting pad securely fixed onto the outer circumferential surface of the hose or duct, the second mounting pad securely fixed onto the adjustable ring shaped clamp, fixing the rotational position and longitudinal spacing adjustable ring shaped clamp on the hose or duct;
wherein the first mounting pad and the second mounting pad are spaced apart in a longitudinal direction and aligned longitudinally.

6. The positionally fixed adjustable clamp according to claim 5 , wherein
the first mounting pad, together with the duct or hose, surrounds and encapsulates a portion of the at least one position fixing leg; and
the second mounting pad extends in a longitudinal direction across and covers a radially outer portion of the adjustable ring shaped clamp.

7. The positionally fixed adjustable clamp according to claim 5 , wherein
the first and second mounting pads are rubber pads or plastic pads;
wherein the mounting pads are permanently secured to the hose or duct by vulcanization, or permanently welded onto the hose or duct.
