Abstract
The disclosure includes a connection method to fluidly connect a fluid pathway in a handle is formed co-linearly or axially and connects to a lumen through a tool and shaft. The body and movable latch may be an integral single molded plastic part connected by a flexible. In operation actuating the movable latch to raise or lower a latching beak within a corresponding open guide in the plastic body. The shaft fits into a shaft guide in the body which intersects the beak guide to temporarily latch the shaft to the body via a mounting fixture the shaft with the beak; and, wherein the body has a face end and a tail end.
Claims21
A connection method to connect a shaft to a body, the method comprising:
- forming, as one piece, a plastic movable latch and a body connected by a hinge;
- actuating the movable latch to raise or lower a latching beak within a corresponding open beak guide in the plastic body;
- inserting a shaft having a lumen running axially into a shaft guide in the body which intersects said beak guide;
- temporarily latching the shaft to the body via a mounting fixture in the shaft with said latching beak;
- wherein the body has a face end and a tail end;
- and,
- wherein a fluid pathway having a larger diameter towards said tail end and a smaller diameter towards said face end is formed axially through said body and configured to fluidly connect through the guide connection to the shaft's lumen.
An ergonomic quick release system comprising:
- a plastic molded handle having a front half comprising a front section and a back half comprising a back section and a tail end;
- a fluid pathway having a larger diameter towards said back section and a smaller diameter towards said front section formed axially from said tail end to an open guide connection;
- a face end with an interface;
- a shaft guide collinear with the interface configured to accept a shaft;
- a beak guide with an open top and an open bottom;
- a plastic flexible hinge portion integrally formed as part of the front half of said handle;
- a plastic movable latch with a first side, a second side and a middle region formed as part of said hinge portion;
- wherein the first side faces the front section and a beak extends therefrom;
- wherein said beak forms a latch cooperating with a mounting fixture;
- and,
- wherein pressing on the movable latch lifts said beak out of said mounting fixture.
A quick release connection comprising:
- a body having a front section, a back section, and a fluid pathway having a larger diameter towards said back section and a smaller diameter towards said front section formed axially therethrough;
- an interface opening at the face end of said front section of said body which is collinear with a shaft guide configured to accept a shaft;
- a beak guide with an open top and an open bottom generally perpendicular to said shaft guide and intersecting said shaft guide;
- a plastic hinge portion integrally formed as part of said body;
- a plastic movable latch with a first side, a second side and a middle region formed as part of said hinge portion;
- a beak extending from said latch into said beak guide;
- and,
- wherein said beak is configured to a latch a corresponding mounting fixture on a shaft.
