Abstract
Abstract A hope coupling is adapted for receptive engagement with a male coupler element having an external annular groove. The hose coupling includes a tubular body having a longitudinally extending bore adapted to receive the male coupler element. At least one slot in the tubular body provides communication from outside the tubular body to the interior of the longitudinal bore. The slot extends axially along the tubular body and radially inwardly with respect to the longitudinal axis of the bore. A pin is mounted in the slot for movement therein from an inner position wherein it protrudes within the bore to an outer position wherein it is positioned outside the bore. A biasing guide collar for the pin includes oppositely disposed side wall members at the opposite ends of the pin and which collar is slidably mounted on the outside of the tubular body. A spring provided on the tubular body biases the collar to urge the pin into its inner position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
175 words
A hose coupling for a male coupler element comprising a tubular body having a longitudinally extending bore formed to receptively engage said male coupler, said tubular body having at least one through slot formed in the outer surface thereof and extending axially along said body and radially inwardly to said bore, at least one pin movably mounted in said slot for movement into said bore, actuating means provided on said tubular body for moving said pin out of said bore, guide means provided on said tubular body for urging said pin into said bore and resilient biasing means engageable with said guide means to bias said guide means against said pin, said guide means being displaceably movable along the axis of said tubular body and formed to abuttingly engage said actuating means when said actuating means moves said pin out of said bore, the abutment of said actuating means and said guide means isolating said pin from the biasing force of said biasing means when said actuating means move said pin out of said bore.
Claim 2
Dependent Claim
175 words
A hose coupling for a male coupler element comprising a tubular body having a longitudinally extending bore formed to receptively engage said male coupler, said tubular body having at least one through slot formed in the outer surface thereof and extending axially along said body and radially inwardly to said bore, at least one pin movably mounted in said slot for movement into said bore, actuating means provided on said tubular body for moving said pin out of said bore, guide means provided on said tubular body for urging said pin into said bore and resilient biasing means engageable with said guide means to bias said guide means against said pin, said guide means being displaceably movable along the axis of said tubular body and formed to abuttingly engage said actuating means when said actuating means moves said pin out of said bore, the abutment of said actuating means and said guide means isolating said pin from the biasing force of said biasing means when said actuating means move said pin out of said bore.
Claim 3
Dependent Claim
23 words
A hose coupling as claimed in claim 1 wherein said tubular body includes two of said through slots, said slots being oppositely disposed.
Claim 4
Dependent Claim
19 words
A hose coupling as claimed in claim 2 wherein a pin is movably mounted in each said through slot.
Claim 5
Dependent Claim
24 words
A hose coupling as claimed in claim 1 wherein said guide means comprise a guide collar having a guide channel for accommodating said pin.
Claim 6
Dependent Claim
28 words
A hose coupling as claimed in claim 4 wherein said pin is recessed within said guide channel during movement of said actuating means against said guide collar isolated.
Claim 7
Dependent Claim
31 words
A hose coupling as claimed in claim 4 wherein said guide channel is defined by spaced and oppositely disposed wall portions on said guide collar at opposite ends of said pin.
Claim 8
Dependent Claim
41 words
A hose coupling as claimed in claim 6 wherein said wall portions project from said guide collar a distance that is dimensionally greater than the diameter of said pin such that said pin can be recessed entirely within said guide channel.
Claim 9
Dependent Claim
52 words
A hose coupling as claimed in claim 7 wherein said actuating means comprise a sleeve slidably mounted on said tubular body for displacement thereon, said sleeve having an internal shoulder formed to abut against the wall portions of said guide means when said actuating means moves said pin out of said bore.
Claim 10
Dependent Claim
37 words
A hosE coupling as claimed in claim 1 further including complementary engaging means on said guide means member and said tubular body member for preventing rotational movement of said guide means with respect to said tubular body.
Claim 11
Dependent Claim
34 words
The hose coupling of claim 9 wherein said engaging means includes a keypin and keyslot, said keypin being provided on one of said members and said keyslot being provided on the other said member.
Claim 12
Dependent Claim
22 words
The hose coupling of claim 9 wherein said engaging means includes complementary flat surfaces on said guide means and said tubular body.
Claim 13
Dependent Claim
178 words
In combination a tubular body having a longitudinally extending bore and a pair of oppositely disposed through slots formed in the outer surface thereof and extending axially along said tubular body and radially inwardly to said bore, a pin movably mounted in each said slot for movement into said bore,a guide collar provided on said tubular body for engagement with said pins to move said pins into said bore, said guide collar being displaceably movable along the axis of said tubular body and including a guide channel for accommodating said pins, said guide channel being defined by spaced and oppositely disposed wall portions on said collar extending away from said collar, each wall portion having a free end at a greater distance from the collar than the diameter of said pins, such that said pins can be entirely recessed within said guide channel, and biasing means on said tubular body engageable with said guide collar for urging said guide collar to move said pins into said bore, and actuating means to move said pins out of said bore.
Claim 14
Dependent Claim
178 words
In combination a tubular body having a longitudinally extending bore and a pair of oppositely disposed through slots formed in the outer surface thereof and extending axially along said tubular body and radially inwardly to said bore, a pin movably mounted in each said slot for movement into said bore,a guide collar provided on said tubular body for engagement with said pins to move said pins into said bore, said guide collar being displaceably movable along the axis of said tubular body and including a guide channel for accommodating said pins, said guide channel being defined by spaced and oppositely disposed wall portions on said collar extending away from said collar, each wall portion having a free end at a greater distance from the collar than the diameter of said pins, such that said pins can be entirely recessed within said guide channel, and biasing means on said tubular body engageable with said guide collar for urging said guide collar to move said pins into said bore, and actuating means to move said pins out of said bore.
