Abstract
Abstract A coupling mechanism is disclosed which is adapted for transverse coupling to a keeper pin. A housing is provided for transversely receiving the keeper pin. Detent bodies associated with the housing are included for releasably coupling to the keeper pin. A sleeve is slidably associated with the housing for releasably locking the detent bodies in a coupled position with the keeper pin. A spring is included for normally biasing both the detent bodies and the sleeve to the detent locking position.

Claims Analysis

Claim 1
Independent Claim
405 words
A coupling mechanism adapted for transverse coupling to a keeper pin which comprises: a housing having a slotted front portion adapted to transversely receive a keeper pin, said slot extending coaxially with the longitudinal axis of said housing; detent means associated with said housing for releasably coupling a keeper pin and movable between coupled and uncoupled positions; a slidable keeper pin receiving member mounted in said housing having a forward end engagable by a keeper pin and keeper pin biasing means associated therewith for normally biasing said member in a direction whereby said detent means abuts against said keeper pin receiving member, thereby retaining said detent means in said uncoupled position until said keeper pin receiving member is moved against its bias to thereby release said detent means permitting said detent means to move to its coupled position, said keeper pin receiving member having a plug attached to its end remote from said forward end and said plug being adapted to abut against the end of said housing remote from said slotted front portion when said keeper pin receiving member is mounted in said housing; sleeve means slidably associated with said housing for releasably locking said detent means in said coupled position and movable between a position locking said detent means in said coupled position and a position allowing movement of said detent means to said uncoupled position, said sleeve means being slotted to transversely receive a keeper pin, said sleeve means slot extending coaxially with the longitudinal axis of said housing, said sleeve means further including a detent body contact surface displaced sufficiently from said housing to permit movement of said detent bodies into said uncoupled position when said sleeve means is in said detent movement allowing position and a locking portion having a locking surface rearward of said front portion, said locking surface retaining said detent bodies in said coupled position when said sleeve means is in said detent locking position; and biasing means for biasing said detent bodies to said coupled position and said sleeve means to said detent locking position including an inwardly sloping biasing surface which connects said front portion detent body contact surface with said locking surface whereby forward slidable movement of said biasing surface when said biasing surface is in contact with said detend bodies causes inward movement of said detent bodies toward said coupled position and a spring for urging said biasing surface in said forward direction.
Claim 2

A coupling mechanism adapted for transverse coupling to a keeper pin which comprises: a housing having a slotted front portion adapted to transversely receive a keeper pin, said slot extending coaxially with the longitudinal axis of said housing; detent means associated with said housing for releasably coupling a keeper pin and movable between coupled and uncoupled positions; a slidable keeper pin receiving member mounted in said housing having a forward end engagable by a keeper pin and keeper pin biasing means associated therewith for normally biasing said member in a direction whereby said detent means abuts against said keeper pin receiving member, thereby retaining said detent means in said uncoupled position until said keeper pin receiving member is moved against its bias to thereby release said detent means permitting said detent means to move to its coupled position, said keeper pin receiving member having a plug attached to its end remote from said forward end and said plug being adapted to abut against the end of said housing remote from said slotted front portion when said keeper pin receiving member is mounted in said housing; sleeve means slidably associated with said housing for releasably locking said detent means in said coupled position and movable between a position locking said detent means in said coupled position and a position allowing movement of said detent means to said uncoupled position, said sleeve means being slotted to transversely receive a keeper pin, said sleeve means slot extending coaxially with the longitudinal axis of said housing, said sleeve means further including a detent body contact surface displaced sufficiently from said housing to permit movement of said detent bodies into said uncoupled position when said sleeve means is in said detent movement allowing position and a locking portion having a locking surface rearward of said front portion, said locking surface retaining said detent bodies in said coupled position when said sleeve means is in said detent locking position; and biasing means for biasing said detent bodies to said coupled position and said sleeve means to said detent locking position including an inwardly sloping biasing surface which connects said front portion detent body contact surface with said locking surface whereby forward slidable movement of said biasing surface when said biasing surface is in contact with said detend bodies causes inward movement of said detent bodies toward said coupled position and a spring for urging said biasing surface in said forward direction.
Claim 3
Dependent Claim
36 words
The coupling mechanism according to claim 1 wherein said detent means include at least two detent bodies associated with said housing at spaced locations adapted to transversely couple to an elongated keeper pin of round cross-section.
Claim 4
Dependent Claim
23 words
The coupling mechanism according to claim 1 which additionally includes an elongated keeper pin of round cross-section for coupling to said detent means.
