Garden Hose With Metal Sheath And Fabric Cover

Patent No. US11732826 (titled "Garden Hose With Metal Sheath And Fabric Cover") was filed by E Mishan & Sons Inc on Nov 8, 2021.

What is this patent about?

’826 is related to the field of garden hoses, specifically addressing improvements to hoses that incorporate a flexible metal sheath. These metal sheaths, while providing durability, can scratch surfaces and become slippery when wet, creating usability issues for consumers.

The underlying idea behind ’826 is to improve the user experience of metal-sheathed garden hoses by adding a fabric sheath over the metal. This fabric layer provides a softer, more grippable exterior, mitigating the scratching and slipperiness problems associated with bare metal.

The claims of ’826 focus on a garden hose comprising an inner polymer tube for water transport, a metal sheath providing structural support and protection, and a fabric sheath covering the metal sheath. The fabric sheath is secured to the metal sheath using constricting bands positioned near shoulders on the metal sheath near each end of the hose.

In practice, the hose functions by having the inner tube carry water under pressure, while the metal sheath protects the inner tube from damage and allows the hose to flex without kinking. The fabric sheath then provides a tactile and protective outer layer. The constricting bands ensure the fabric sheath remains in place, preventing it from sliding or bunching up along the length of the hose.

This design differentiates itself from prior art by adding the fabric sheath to address the specific problems of scratching and slipperiness. Unlike hoses with bare metal sheaths, this design offers a more user-friendly experience. The fabric is not directly attached to the metal sheath, allowing for some relative movement and maintaining flexibility, while the constricting bands provide securement without hindering the hose's overall bendability.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2020s when ’826 was filed, garden hoses were typically constructed with inner tubes made of flexible polymer materials. At a time when metal sheaths were commonly used to protect these inner tubes, the metal sheaths themselves could pose problems such as scratching surfaces or becoming slippery. When hardware or software constraints made adding an additional protective layer non-trivial, alternative solutions were needed to address these issues.

Novelty and Inventive Step

The examiner approved the application because they believed the claimed garden hose was novel and non-obvious. No prior art disclosed a hose with a polymer inner tube for conveying water between couplers, a metal sheath with shoulders near the couplers, and a fabric sheath fixed to the metal sheath by constricting bands at those shoulders.

Claims

The patent has 12 claims, with claim 1 being independent. Independent claim 1 is directed to a garden hose with a specific layered construction including an inner tube, metal sheath, and fabric sheath. The dependent claims elaborate on the features of the garden hose described in claim 1, such as the materials of the sheaths, the burst pressure, and the construction of the couplers.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Constricting band
(Claim 1)
“Constricting band 103 is disposed on the outside of fabric sheath 102 and is tightly fitted to pin fabric sheath 102 against sheath 114 and in place on hose 100. Constricting band 103 is disposed adjacent to a shoulder 104 of steel sheath 114 the shoulder having a larger diameter at its largest extent than band 103. Constricting band 103 may be in the form of a band or bands, rope or ropes, or wire or wires, made of nylon, metal, or any other suitable material.”A band that secures the fabric sheath to the metal sheath at the shoulders of the metal sheath.
Fabric sheath
(Claim 1)
“According to an embodiment of the subject technology, as best shown in FIGS. 1-3, woven fabric sheath 102 is disposed over steel sheath 114. Fabric sheath 102 may be a continuous seamless tube of fabric material or may be formed as a sheet of fabric material with opposite edges joined at a seam running the length of the sheath to result in a tube of fabric material. The fabric material may be natural fabric, or synthetic fabric, or a natural-synthetic fabric blend.”An outer covering placed over the metal sheath, secured by constricting bands at the shoulders of the metal sheath.
Metal sheath
(Claim 1)
“Sheath 114 may be in the form of spirally wound turns of sheet metal, with each turn interlinked with a next turn along the hose body to form a flexible metal sheath. Constricting band 103 is disposed adjacent to a shoulder 104 of steel sheath 114 the shoulder having a larger diameter at its largest extent than band 103. Any suitable shoulder-like feature of steel sheath 114 disposed near ends of the steel sheath 114 may be used for this purpose.”A flexible outer covering for a garden hose's inner tube, extending between the couplers and having shoulders near each coupler.
Polymer inner tube
(Claim 1)
“Within metal sheath 114, an inner tube of flexible polymer material is inside the hose 100 and extends the length of the hose between couplers 118, 119, for conveying water through the hose 100. Metal sheath 114 also extends the length of the hose between couplers 118, 119 to protect the inner tube.”A waterproof and flexible tube inside the metal sheath for conveying water.
