Vari-stage coupling device
View Patent ↗A Vari-Stage Coupling device that accomplishes the goal of coupling different styles of tubing in one device. The coupling device allows the user to incorporate different sizes of tubing into a single fitting decreasing the confusion as to which part fits with which tubing and decreasing his time looking for the right fitting. The coupling device also allows the user to need to use only one device for most all of his coupling needs.
1. A Variable Stage Coupling Device for conjoining flexible tubing comprising;
an exterior portion possessing a facing surface, having a centerpoint along a central axis perpendicular to said facing surface and an opening to allow ingress of said flexible tubing;
an interior portion, axially aligned with said exterior portion, having a centerpoint, possessing a common central axis with said exterior portion, an exiting surface and an opening to allow for egress of said flexible tubing;
a first angularly aligned conical section, interiorly inclined emanating from said exterior portion toward said centerpoint of said interior portion, axially aligned with said common central axis, following a consistent angle α terminating at a first edge that is formed by a first plane bisecting said first angularly aligned conical section;
a second angularly aligned conical section, interiorly inclined emanating from said first edge of said first angularly aligned section, sloped inwardly toward said centerpoint of said interior portion, coaxial with said first angularly aligned section, following a consistent angle of β, said second angularly aligned conical section terminating at a second edge formed by a second plane bisecting said second angularly aligned conical section, said second plane being parallel to said first plane; and
a reverse angularly aligned conical section, interiorly inclined emanating from said exiting surface of said interior portion toward said centerpoint of said exterior portion, axially aligned with said common central axis, following a consistent angle γ terminating at a step point along said bisecting second plane, said step point is located radially below the intersection of said second plane and said second angularly aligned conical section.
2. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where angle β is between 45-55 degrees.
3. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where angle α is between 20-30 degrees.
4. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where angle γ is between 45-75 degrees.
5. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where said device is integral with a separable housing, said housing being capable of attachment to a variety of coupling device bodies.
6. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where said device is configured to be integral therewith a single housing.
7. A Variable Stage Coupling Device for conjoining flexible tubing as in claim 1 where said opening of said exterior portion is shaped to match the profile of said flexible tubing.
