A flexible tube includes an envelope, a spiral tube and a built-in component. The spiral tube includes a first area portion and a second area portion. The spiral tube is under an initial tension throughout the overall length, and the built-in component includes a supplement area portion which supplements the elasticity of the spiral tube.

A hose connector (5) which can be fixed to the hose end region of a flexible hose (6) and includes an outer part (7), which surrounds the hose end region, and an inner part (8), which can be inserted into the clear cross section of the hose. The inner part (8) is in the form of a hollow rivet and is deformable between an initial form, which can be inserted into the clear cross section of the hose at the hose end region, and a widened form, which sealingly and fixedly clamps the at least one hose between the inner part (8) and the outer part (7). A hose line that can also be formed for example as a two-chamber or multi-chamber hose line is provided. Moreover, a method for producing a hose connector on the hose end region of a flexible hose is provided.

An antistatic flexible hose, including: a hose body which is formed of a soft material having flexibility; a conductive layer which is provided along an outer peripheral face of the hose body in an axial direction; a conductive wire which is wound in a spiral shape along the outer peripheral face of the hose body and an outer surface of the conductive layer and which is provided so as to be pressure-welded, in a radial direction, to the outer peripheral face of the hose body and the outer surface of the conductive layer; and a reinforcing member which is provided in a spiral shape along the conductive wire so as to protrude from the outer peripheral face of the hose body and the outer surface of the conductive layer.

A metal braided hose includes: an inner tube including an elastic material; a first metal wire braided layer enveloping an outer surface of the inner tube; and a second metal wire braided layer enveloping the first metal wire braided layer. A wire thickness of the second metal wire braided layer is smaller than a wire thickness of the first metal wire braided layer.

A garden hose has an inner tube for conveying water at domestic water pressure from a first coupler disposed at a first end of the inner tube to a second coupler disposed at a second end of the inner tube, the inner tube being waterproof and flexible, the first coupler adapted to threadedly connect to a conventional water faucet and the second coupler adapted to threadedly connect to a conventional garden appliance. The hose has a metal sheath disposed over the inner tube and extending from the first coupler to the second coupler, the flexible metal sheath having a first shoulder near the first coupler and a second shoulder near the second coupler, the metal sheath being flexible, and a fabric sheath disposed over the metal sheath and fixed to the metal sheath by a first constricting band disposed at the first shoulder and a second constricting band disposed at the second shoulder.

The rigid hose for wet dry vacuum is configured for use with the hose of a domestic appliance. The rigid hose for wet dry vacuum is a protective structure. The rigid hose for wet dry vacuum protects the hose. The rigid hose for wet dry vacuum sets the hose in a fixed position such that the curvature of the center axis of the prism structure of the hose will not shift during use of the hose. The rigid hose for wet dry vacuum comprises a bimodal shell. The bimodal shell is a bimodal flexible structure.

Apparatus and methods for removing and/or destroying support structures associated with objects fabricated using additive manufacturing techniques are presented herein. Structural supports may be used during an additive manufacturing process to prevent deformation of a build piece (e.g., three dimensional (3D) printed structure). In some examples, a build piece may be manufactured such that the structural supports are internal to the completed build piece. However, removing the structural supports may reduce the weight of the build piece and reduce the amount of debris trapped within the build piece. Thus, certain aspects of the disclosure are directed to a hose including a bendable and elongated tube member as well as a fracturing member configured to fracture an internal support structure within an additively manufactured part.
