Abstract
A locking clip for use with a hose coupling is provided that includes a first member and a second member that grasp and maintain a locking arm of a locking mechanism commonly used in conjunction with hose couplings.
Claims19
A hose coupling locking clip adapted for constraining locking arms of a hose coupling that includes a clevis portion with a rotatably interconnected locking arm, comprising:
- a plate having a right edge with a right wall extending therefrom and a left wall with a left wall extending therefrom, the distance between said left edge and said right edge defining a first width;
- a left locking shoulder having a first edge and a second edge, said first edge interconnected to said left wall wherein said left locking shoulder is angled with respect to said left wall;
- a right locking shoulder having a first edge and a second edge, said first edge interconnected to said right wall wherein said right locking shoulder is angled with respect to said right wall and wherein a second distance between said second edge of said left locking shoulder and said second edge of said right locking shoulder is less than said first distance;
- a left locking wing wall interconnected to said second edge of said left locking shoulder, said left locking wing wall angled with respect to said left locking shoulder in a direction toward said left wall;
- a right locking wing interconnected to said second edge of said right locking shoulder, said right wing angled with respect to said right locking shoulder in a direction toward said right wall;
- a left clevis plate interconnected to said left locking shoulder and generally parallel thereto;
- a right clevis plate interconnected to said right locking shoulder and generally parallel thereto;
- a left retention tab interconnected to said left clevis plate about 90 degrees relative thereto;
- a right retention tab interconnected to said right clevis plate about 90 degrees relative thereto;
- wherein said left clevis plate and said right clevis plate are adapted to be associated with the clevis of the hose coupling with the locking arm positioned therebetween;
- and
- wherein when the locking arm of the hose coupling is positioned adjacent to said plate, said left locking shoulder and said right locking shoulder prevent movement of the locking arm without deflection of said left locking wing wall and said right locking wing.
A hose coupling locking clip adapted for constraining locking arms of a hose coupling that includes a clevis portion with a rotatably interconnected locking arm, comprising:
- a plate having a right edge with a right wall extending therefrom and a left edge with a left wall extending therefrom;
- a left shoulder interconnected to said left wall;
- a right shoulder interconnected to said right wall;
- a left clevis plate interconnected to said left wall;
- a right clevis plate interconnected to said right wall, said left clevis plate and said right clevis plate being adapted to be associated with the clevis of the hose coupling with the locking arm positioned between said left clevis plate and said right clevis plate;
- and
- wherein when the locking arm of the hose coupling is positioned adjacent to said plate, said left shoulder and said right shoulder restricts movement of the locking arm.
A hose coupling locking system for integration with a hose coupling that generally includes a female portion for receiving a fluid conveying member, said female portion having an opening, said hose coupling also including a locking arm with a locking arm end that is rotatably interconnected to said female portion by way of a pin and clevis, wherein said locking arm is capable of moving from a first position of use where said locking arm end is positioned through said opening and in engagement with the fluid conveying member and a second position of use wherein said locking arm end is positioned such that the fluid conveying member is capable of freely interconnecting or disconnecting from said female portion, comprising:
- a first locking member having a first clevis wall with an aperture therethrough that is positioned between said clevis and one side of said locking arm with said pin extending through said first clevis wall;
- a first wall interconnected to and extending from said first clevis wall;
- and
- a first shoulder wall interconnected to and extending at an angle relative to said first wall such that when said locking arm is in a first position of use, said first shoulder wall prevents said locking arm from moving to said second position of use.
