Abstract

The present invention relates to a high impact hose coupling having a hollow body constructed of plastic, a helical restriction means to hold the hose end within the coupling body, a double locking means for locking coupling halves together, and a static electric conducting gasket to allow the conduction of static electricity within the coupling.

Claims

1. A high impact hose coupling apparatus comprising:

a hollow coupling body further comprising a hose retention means disposed at an outside diameter of the coupling body half, a hose restriction means disposed on an inside diameter surface of the hollow coupling body half, a plurality of partially annular flange surfaces extending radially outward at a first end of the coupling body half and each flange surface having a raised portion on at least one lateral surface, a plurality of ears disposed at the first end of the coupling body half which extend in an axial direction of the coupling body half having cut-outs to receive the flange surfaces with at least one raised portion of a flange of a second coupling body half in a locking relationship, an annular groove extending into the first end of the coupling body half;

a spring locking means disposed at a first end of the coupling half body having a retractable portion extending through the flange surface for disposition in a second coupling body half preventing relative rotation between a first and second coupling body half in a locking relationship;

a static electricity dissipating means disposed in the annular groove.

3. The coupling apparatus, as recited in claims 1 or 2, wherein the hose retention means are a plurality of holes in the hollow body capable of receiving screws in a screw/nut relationship to hold a hose disposed in the coupling body half.

4. The coupling apparatus, as recited in claims 1 or 2, wherein the hose restriction means is a raised helical rib disposed on the inside diameter of the body.

5. The coupling apparatus, as recited in claims 1 or 2, wherein the coupling body half is made of a high impact plastic.

6. The coupling apparatus, as recited in claims 1 or 2, wherein the static electricity dissipating means is a gasket.

7. The coupling apparatus, as recited in claims 1 or 2, wherein the coupling dissipates static electricity through the interior of the coupling body with a hose end disposed therein and through the inside diameter of the gasket.

2. A high impact coupling apparatus comprising:

a hollow coupling body further comprising a hose retention means, a hose restriction means on an inside diameter surface, a plurality of flange surfaces extending radially outward at a first end of the coupling half body, a raised portion of a lateral surface of each flange, a plurality of ears to engage the flange surfaces in a locking relationship disposed at a first end;

a spring locking means disposed at a first end to prevent rotational displacement of two coupling halves when in a locking realtionship;

a static electricity dissipating means disposed in an end of the coupling body half.
