Abstract

A quick release coupler system is provided. The coupler system has a female housing unit having an interior passageway for receiving a fluid, such as grease, from a male housing unit. The interior passageway of the female housing unit has a plurality of pins located within a plurality of cavities. The plurality of pins move from a first position to a second position within the plurality of cavities. The pins of the female housing unit removably lock onto a corresponding male housing unit. Once the female housing unit is locked onto the male housing unit, a fluid passageway between the female housing unit and the male housing unit is created and a fluid may flow from the female housing unit to the male housing unit.

Claims (10)

1 . A quick release coupler system having: a female housing unit having an exterior surface and an interior passageway having a hollow portion: a male housing unit having an exterior surface and an interior passageway having a hollow portion; wherein the interior passageway of the female housing unit has a has at least one cylindrical hollow space and wherein at least one pin is located partially within the cylindrical hollow space of the female housing unit; wherein the pin moves from a first position to a second position within the cylindrical hollow space of the female housing unit; and wherein the pin locks the female housing unit to the male housing unit.
2 . The quick release coupler system of claim 1 wherein the cylindrical hollow space is not parallel to the interior passageway of the female housing unit.
3 . The quick release coupler system of claim 1 wherein the cylindrical hollow space is not perpendicular to the interior passageway of the female housing unit.
4 . The quick release coupler system of claim 1 wherein the pin is made of steel.
5 . The quick release coupler system of claim 1 wherein the pin has a first end and a second end and wherein the first end and the second end of the pin have different diameters.
6 . The quick release coupler system of claim 1 wherein the angle of the cylindrical hollow space is between forty and eighty degrees with respect to the interior passageway of the female housing unit.
7 . The quick release coupler system of claim 1 further comprising: a spring located within the female housing unit wherein the spring surrounds the interior passageway of the female housing unit.
8 . The quick release coupler system of claim 1 further comprising: a movable sleeve surrounding the interior passageway of the female housing unit wherein the movable sleeve moves from a first position to a second position.
9 . The quick release coupler system of claim 1 further comprising: a first end of the male housing unit wherein the first end of the male housing unit has an indented ring and wherein the indented ring receives the pin of the female housing unit.
10 . The quick release coupler system of claim 1 further comprising: a terminal end of a ledge of the movable sleeve wherein the terminal end of the ledge of the movable sleeve has an indented portion forming a space and wherein the space may receive the pin.

Description

REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Application No. 63/715,531 filed on Nov. 2, 2024, the entire contents of which are incorporated by reference herein. BACKGROUND OF THE INVENTION A quick release coupler system is provided. The coupler system has a female housing unit having an interior passageway for receiving a fluid, such as grease, from a male housing unit. The interior passageway of the female housing unit has a plurality of pins located within a plurality of cavities. The plurality of pins move from a first position to a second position within the plurality of cavities. The pins of the female housing unit removably lock onto a corresponding male housing unit. Once the female housing unit is locked onto the male housing unit, a fluid passageway between the female housing unit and the male housing unit is created and a fluid may flow from the female housing unit to the male housing unit. Couplers for fluids are common. For example, U.S. Publication No.: 20080190489 to Wrubel discloses a chuck for connecting a pressure device to a valve stem of a pressurized vessel includes a body portion having a first passageway that is configured to receive an outer tube portion of a valve stem of a pressurized vessel therein. The body portion has a guide portion at an inner end of the first passageway. A pin element is movably disposed within a second passageway of the body portion and is movable along the coaxial passageways. The pin element extends longitudinally from the guide portion and toward an engaging end of the body portion. The guide portion includes an alignment element at least partially around the second passageway and extending longitudinally toward the engaging end of the body portion and at least partially around the pin element for engaging and supporting an interior portion of the end of the outer tube portion of the valve stem. Further, U.S. Pat. No. 4,458,719 to Strybel discloses a service connection including a first coupler adapter mounted to a service hose end fitting and a second coupler adapter mounted to a service fitting. In the illustrated embodiment, the adapters are threadedly connected to the hose end fitting and service fitting, respectively, and are provided with structure for effecting a quick connection between the adapters and, thus, between the service hose and service fitting. In one embodiment, the hose fitting adapter defines a rectilinear through passage, and in another embodiment, the hose fitting adapter defines a right angle turn flow passage. The hose fitting adapter is provided, in the illustrated embodiment, with a core depressor for engaging an opening in the core valve of the service fitting upon sealed connection of the adapters. The hose fitting adapter may be provided with a shutoff valve which is adapted to be opened by the engagement of the core depressor thereof with the core valve of the service fitting. However, these patents fail to describe a quick release coupler system which is easy to use. Further, these patents fail to provide for a quick release coupler system which allows a user to easily and efficiently secure a female housing unit to a male housing unit in the manner described herein. SUMMARY OF THE INVENTION A quick release coupler system is provided. The coupler system has a female housing unit having an interior passageway for receiving a fluid, such as grease, from a male housing unit. The interior passageway of the female housing unit has a plurality of pins located within a plurality of cavities. The plurality of pins move from a first position to a second position within the plurality of cavities. The pins of the female housing unit removably lock onto a corresponding male housing unit. Once the female housing unit is locked onto the male housing unit, a fluid passageway between the female housing unit and the male housing unit is created and a fluid may flow from the female housing unit to the male housing unit. An advantage of the present quick release coupler system is that the present quick release coupler system is ideal for coupling a male unit and female unit in a fluid line, for example, a grease line or air line. Another advantage of the present quick release coupler system is that the present quick release coupler system is durable. And another advantage of the present quick release coupler system is that the present quick release coupler system has movable pins which lock a female housing unit to a male housing unit. Another advantage of the present system is that the present quick release coupler system is durable. For example, the pins of the present system may be made of a durable steel. For a more complete understanding of the above listed features and advantages of the quick release coupler system reference should be made to the detailed description and the drawings. Further, additional features and advantages of the invention are described in, and will be apparent from, the d
