Quick connect coupling
First Claim
1. A coupling comprising:
- a male and female half that are coupled together in axial alignment,a keying portion at one end of said male half having at least one keying element with a bearing surface, and an end portion,an opening in the side of said female half having a recess therein shaped for location of said keying element, said opening allowing said keying portion to engage said opening in a direction transverse to said aligned axis for connecting said coupling, said recess having abutment surfaces against which said bearing surface locates when engaged, said bearing and abutment surfaces preventing separation of said coupling when placed under tension along said aligned axis,a locking member within said female half engageable with the end portion of said keying portion to prevent said keying portion disengaging from said recess, said locking member journaled for movement along the longitudinal axis of said female half, anda cover slidably secured to said female half, said cover engageable with said locking member to move said locking member along the longitudinal axis of said female half.

Abstract
A coupling comprising a male and female half (11, 12) that are coupled together in axial alignment. A keying portion (13) is provided at one end of the male half (11) which has at least one keying element (14) with a bearing surface (20). The female half (12) has an opening (17) located on one side with recesses (18) therein shaped for location of the keying element (14). The opening (17) allows the keying portion (14) to engage the opening (17) in a direction that is transverse to the aligned axis. The recess (18) has abutment surfaces (21) against which the bearing surfaces (20) locate when the keying portion (14) is engaged within the recess (18). The bearing (20) and abutment (21) surfaces prevent separation of the coupling when placed under tension along the aligned axis. The invention provides a simplified means for connection of the coupling while at the same time allowing relative rotation between the male and female halves (11, 12).

13. A coupling comprising a male and female half that are coupled together in axial alignment,
a keying portion at one end of said male half having at least one keying element with a bearing surface, an opening in the side of said female half having a recess therein shaped for location of said keying element, said opening allowing said keying portion to engage said opening in a direction transverse to said aligned axis for connecting said coupling, said recess having abutment surfaces against which said bearing surface locates when engaged, said bearing and abutment surfaces preventing separation of said coupling when placed under tension along said aligned axis, and a rope socket secured to one end of said coupling comprising: -
a socket body having a first end secured to said coupling and a second end, a first bore extending part-way into said socket body from the first end of the socket body, a second bore of a diameter that is smaller than said first bore, said second bore extending from the second end of said socket body to the first bore, and a side opening in said socket body that opens a part of said first bore. - View Dependent Claims (14, 15)
