Definitions

  • the present invention relates to pneumatic air hoses. More specifically, the present invention pertains to an improved air hose that is utilized in conjunction with an air compressor and a variety of pneumatic tools such as blow guns, nail guns, and air staplers.
  • An air compressor is a device that converts power from a motor or engine into energy to compress air.
  • the compressed air is generally contained within a pressure vessel, and the release of the compressed air can be triggered in quick bursts.
  • Two of the most common uses for an air compressor are inflation and pneumatic tools.
  • An inflation attachment includes a nozzle that allows one to inflate everything from beach balls to automobile tires.
  • Pneumatic tools are generally faster, lighter and more powerful than traditional power tools.
  • Some pneumatic tools that are useful with an air compressor include: a blown gun, a nail gun, an air stapler, and a spray gun.
  • An air compressor is usually attached to a pneumatic tool by an elongated air hose.
  • these hoses can be bulky and cumbersome to work with.
  • Such elongated hoses can be easily tangled and frustrating to unwind and rewind neatly for each use.
  • a traditional hose also may require significant storage space. Therefore, there exists a need for an improved air hose that is compact and configured for use with air compressors.
  • Devices have been disclosed in the prior art that relate to hoses. These include devices that have been patented and published in patent application publications. Devices in the art include those that expand longitudinally and laterally upon the application of fluid pressure. Other devices include a hose for fluids having an inner tube member made from elastic material and an outer tube member made from a non-elastic material. These prior art devices, however, do not disclose a hose utilized with an air compressor and having the structure of the present invention. The foregoing is a list of devices deemed most relevant to the present disclosure, which are herein described for the purposes of highlighting and differentiating the unique aspects of the present invention, and further highlighting the drawbacks existing in the prior art.
  • U.S. Patent Number 8,291,942 to Berardi discloses a hose that expands longitudinally and laterally upon the application of fluid pressure.
  • the Berardi device can expand longitudinally up to six times its contracted length.
  • the Berardi device discloses an inner tube made from elastic material and an outer tube made from non-elastic material.
  • the inner tube is positioned concentrically within the outer tube secured by the first end and second end of both inner and outer tubes.
  • hose having an inner tube member made from elastic material and an outer tube member made from a non-elastic material.
  • the inner tube member is secured to the outer tube at the ends by an inlet coupler and an outlet coupler.
  • the inlet coupler is adapted to secure to a water supply and the outlet coupler is coupled to a flow restrictor allowing the inner tube to equalize in pressure with water received from water supply. Water expands the inner tube longitudinally and laterally.
  • U.S. Patent Number 4,895, 185 to Champleboux discloses a flexible hose and expandable hose for utilization in fields.
  • the Champleboux device discloses a hose including at least two pairs of adjacent reinforcing layers made of flexible cables disposed helically and attached to at least one rigid end piece.
  • Rigid end piece include an inner supporting element and an outer gripping element.
  • Inner supporting element and outer gripping element are coaxial and having conical compression surfaces, which diverge toward one end.
  • the Champleboux device is a hose for well packers.
  • U.S. Patent Number 6,889,701 to Kovacik discloses a reel for storing an air hose having a spring-loaded pulley system mounted therein.
  • the reel includes a hollow reel housing with a flange mounted thereon exterior of the housing, a pulley rotatably mounted inside the housing.
  • the pulley further includes a nozzle mounted thereon.
  • a reel hose is wound on the pulley with one end attached to the nozzle.
  • the devices disclosed in the prior art have several known drawbacks. These devices are limited as they are not adapted for use with an air compressor.
  • One invention discloses a hose that expands longitudinally and laterally upon the application of fluid pressure.
  • Another invention discloses a hose for fluids having an inner tube member made from elastic material and an outer tube member made from a non-elastic material.
  • an expandable pneumatic air hose formed from an inner elastic tubular member surrounded by an outer inelastic tubular sleeve.
  • the process is carried out by connecting one end of the elastic tubular member to an air compressor and connecting the other end thereof to a pneumatic tool, engaging the air compressor to expand the inner tubular member to an extended state while the outer tubular sleeve is extended along with the inner tubular member to a length greater than the original non- extended state.
  • the expandable hose resumes its original non-extended state.
  • FIG. 1A is a perspective view of the expandable air hose of this invention in the non-extended state.
  • FIG. IB is a perspective view of a portion of the extendable air hose in the extended state.
  • FIG. 2A is a cross section of an end of the expandable hose in the non-extended state.
  • FIG. 2B is a plan view of the extendable air hose in the non-extended state having a length D.
  • FIG. 3 A is a cross section of the extendable air hose in the extended state.
  • FIG. 3B is a plan view of the extendable air hose in the extended state having a length D2.
  • FIG. 4 is a plan view illustrating the pneumatic air hose in its operational mode.
  • a pneumatic air hose may be formed so as to be extendable for use with pneumatic tools while having a non-extended shorter state for storage when not in use.
  • Figure 1 A is a perspective view in partial cutaway of the extendable hose 1
  • the extendable hose has an inner tubular elastic member 3 surrounded by a tubular inelastic sleeve 5.
  • Inner elastic tubular member 3 is connected to pneumatic fitting 7 which can be connected to a pneumatic tool or air compressor in the conventional mode.
  • a handle 9 facilitates attachment.
  • the expandable air hose 1 when inflated extends to approximately one and one-half to two times its non-extended state. When extended the outer non-elastic tubular sleeve 5 is extended along with the elastic tubular member 3. Inelastic sleeve 5 is capable of extending to the greater length due to a very loose ruffling about the elastic tubular member 3.
  • Figure 3 A is a partial cutaway view of the extendable hose 1 in the extended state.
  • Figure 3 A is a plan view of the expandable pneumatic hose 1 in the non-extended state having a length D.
  • Figure 3B is a plan view showing the expandable hose 1 in the extended state having a length D2.
  • the ratio D2 to D is within the range of 1.5 to 2. This extension occurs upon application of compressed air at a pressure within the range of 90- 120 psi.
  • Figure 4 is a plan view of the expandable hose 1 connected to an air compressor
  • the expandable hose 1 When inflated and extended the expandable hose 1 has the extended length to facilitate use thereof. However, when the air compressor is disengaged the expandable hose has memory and returns to the original non-extended state.
  • Suitable materials of construction for the outer tubular inelastic sleeve are nylon or other inelastic materials.
  • the inner elastic tubular member 3 is preferably formed from a thermoplastic elastomer or natural butyl rubbers. In test of the expandable hose it has been found that pressures up to 600 psi may be achieved without rupture of the elastic tubular member.

Abstract

L'invention concerne un tuyau d'air pneumatique qui est formé à partir d'un élément tubulaire élastique interne entouré par un élément tubulaire non élastique externe. Pendant l'utilisation, une extrémité du tuyau d'air est raccordée à un compresseur d'air et l'autre extrémité à un outil pneumatique. Lorsqu'ils sont en prise l'un avec l'autre, le tuyau d'air pneumatique et l'élément tubulaire élastique interne se dilatent jusqu'à un état étendu tandis que le manchon tubulaire externe est étendu conjointement avec l'élément tubulaire interne jusqu'à une longueur supérieure à la longueur dans l'état d'origine non étendu. Lors du désengagement du compresseur d'air, le tuyau extensible reprend son état initial non étendu.
