Abstract:
A detachable hose coupling having improved interlocking U-shaped staple, which includes:a generally cylindrical female sleeve piece having a pair of coaxially aligned bored open surfaces which are in opposing generally equidistant positions and displaced from a vertical plane passing through a central longitudinal axis of said female sleeve piece and further has a longitudinal axial open surface extending therethrough in communication with said bored open surfaces;a generally cylindrical male piece of a size and configuration to permit insertion into said female sleeve piece wherein said male piece has a longitudinal axial open surface extending therethrough and further has external recessed surface portion which when said male piece is inserted into said female sleeve piece is generally alignable with said bored surfaces to provide an interconnecting open surface through said detachable hose coupling, and wherein said recessed surface is further defined to provide a first line of contact of a first predetermined configuration in said interconnecting open surface and said bored open surfaces each provide a second and third line of contact of a second predetermined configuration in said interconnecting open surface; anda generally U-shaped staple having a cross-sectional with at least a first peripheral surface of a complimentary configuration to said first predetermined configuration for contact with said first line of contact and having a second peripheral surface of a complimentary configuration to said second predetermined configuration for contact with said second line and third lines of contact, wherein at least one of said first peripheral surface and said second peripheral surface includes at least one radially recessed surface portion to permit a predetermined amount of fluid flow thereby, and wherein said U-shaped staple has a generally D-shaped cross-section having and radially recessed surface defined in said second peripheral arcuate surface.
