Abstract

A garden hose with an outer flexible sheath of spirally wound and linked turns of sheet material, an inner tube of flexible polymer inside the sheath and end couplers with nipples press fit into ends of the tube and connector mechanisms connecting the couplers to the outer sheath. Each connector mechanism has inner and outer press fit shells at the end of the sheath, with flared ends separated by a washer.

First claim

What is claimed is:

1. A garden hose comprising:
a hose body ( 12 ) of at least about 10 feet in length;
the hose body comprising a flexible metal outer sheath ( 14 ), and an inner tube ( 16 ) of flexible, waterproof polymer material strong enough to withstand domestic water pressure, the inner tube being inside and extending along the length of the outer sheath ( 14 );
a first coupler ( 18 ) having a first nipple ( 18 a ) press fit into a first end of the inner tube ( 16 ), the first coupler ( 18 ) being adapted to connect the garden hose to a water faucet;
a second coupler ( 20 ) having a second nipple ( 20 a ) press fit into a second end of the inner tube ( 16 ), the second coupler ( 20 ) being adapted for discharging water from the garden hose;
a first connector connecting the first coupler to a first end of the outer sheath and a second connector connecting the second coupler to a second end of the outer sheath;
wherein the first connector or the second connector comprises:
an inner metal shell ( 22 ) having an inner hollow cylindrical body ( 22 a ) engaged over one end of the inner tube ( 16 ), the inner cylindrical body ( 22 a ) having a flared end ( 22 b ) press fit over the one end of the inner tube ( 16 ) into which the nipple ( 18 a , 20 a ) of one of the couplers is inserted, the inner cylindrical body ( 22 a ) also having an opposite unflared end ( 22 c ), the inner cylindrical body ( 22 a ) including an annular enlargement ( 22 d ) between the ends thereof, with at least a portion of the inner cylindrical body ( 22 a ) including the opposite unflared end ( 22 c ), being inside one end of the outer sheath ( 14 );
an outer metal shell ( 24 ) having an outer hollow cylindrical body ( 24 a ) engaged over the inner cylindrical body ( 22 a ), the outer hollow cylindrical body ( 24 a ) having a flared end ( 24 b ) adjacent to but spaced outwardly of the flared end ( 22 b ) of the inner cylindrical body ( 22 b ), the outer hollow cylindrical body ( 24 a ) having a large diameter portion ( 24 d ) and an opposite unflared end ( 24 c ) at the large diameter portion ( 24 d ), the large diameter portion ( 24 d ) being over the annular enlargement ( 22 d ) of the inner hollow cylindrical body ( 22 a ) and the portion of the inner cylindrical body that is inside the one end of the outer sheath ( 14 );

a fixing washer ( 26 ) in the space between the flared ends ( 22 b , 24 b ) of the inner and outer cylindrical bodies ( 22 a , 24 a );
the large diameter portion ( 24 d ) and unflared end ( 24 c ) of the outer hollow cylindrical body ( 24 a ) being press fit radially to the annular enlargement ( 22 d ) and unflared end ( 22 c ) of the inner hollow cylindrical body ( 22 a ) with the one end of the outer sheath ( 14 ) between portions of the inner and outer shells ( 22 , 24 ), for positively fixing the shells to the outer sheath ( 14 ); and
a hollow sleeve ( 28 ) having a body ( 28 a ) extending around the outer metal shell ( 24 ) and one end ( 28 b ) fixed to one of the couplers, the body ( 28 a ) of the a hollow sleeve ( 28 ) having an inner small diameter ring portion ( 28 c ) engaged behind the fixing washer ( 26 ) for positively securing the shells.

2. The garden hose of claim 1 wherein the length of the hose body is about 25 feet.

3. The garden hose of claim 1 wherein the length of the hose body is about 50 feet.

4. The garden hose of claim 1 wherein the length of the hose body is about 100 feet.

5. The garden hose of claim 1 wherein the length of the hose body is longer than 100 feet.

6. The garden hose of claim 1 further comprising a hollow tapered sleeve having a body extending around the first connector and one end fixed to the first coupler, the sleeve tapering outwardly away from the first coupler to leave room for the hose body to bend freely but within the sleeve near the first coupler.

7. The garden hose of claim 1 further comprising a hollow tapered sleeve having a body extending around the second connector and one end fixed to the second coupler, the sleeve tapering outwardly away from the second coupler to leave room for the hose body to bend freely but within the sleeve near the second coupler.

8. The garden hose of claim 1 , wherein the first coupler is a female coupler with a fixed portion connected to the first nipple and a moveable portion movably mounted to the fixed portion.

9. The garden hose of claim 1 , wherein the second coupler is a male coupler and comprises a holding disc to help a user firmly hold the second coupler while threading a nozzle or spray head onto the second coupler.
