Description

TUBE CONNECTOR INCLUDING LOCKING CAPTURE FINGERS
FIELD
[0001] The present disclosure relates to tube connectors, and, more particularly, to a tube connector mostly interior to connected piping with external locking capture fingers.
BACKGROUND
[0002] Tube connector systems can be both larger and more cumbersome than desirable in an environment having fluid carrying pipes, particularly those connectors that are primarily exterior to connected piping. Current systems may further limit use of smart systems, smart tools, torque-sensing connection verification, and hands-free tightening. Systems may also lack double redundancy if clamps fail or a way to verify that a connection is successful before putting the tube connector system into use. Therefore, there is a need in the market for an improved tube connector to connect piping and allow fluid to travel from one pipe to the other.
SUMMARY
[0003] Disclosed is a tube connector system that has a connector body with a proximal end and a distal end. A through-passage is open through the connector body from the proximal end to the distal end and circumscribes a longitudinal center of the connector body. Present is a stepped outer surface of the connector body wherein a center step defines the functional transverse center and the greatest diameter of the connector body, at least one proximal step and at least one distal step of lesser diameter extending longitudinally from the center step and terminating respectively at the proximal and distal ends. The center step is designed to be abutted by the open ends of two connected pipes, the connected pipes of a lesser diameter than the center step, one pipe circumscribing the at least one proximal step and the other pipe circumscribing the at least one distal step, the through-passage of the connector body creating a pathway for liquid from one pipe to the other.
[0004] At least one proximal O-ring seal member and at least one distal O-ring seal member are disposed partially within connector grooved portions circumscribing the outer surface of the connector body on, respectively, at least one proximal step and at least one distal step extended from the center step, the O-ring seal members designed to abut, be circumscribed by, and be partially compressed toward the longitudinal center by the inner surface of connected piping to create 360-degree seals.
[0005] Parallelly oriented proximal and distal capture fingers circumscribe the center step longitudinally apart from the functional transverse center of the connector body. The capture fingers are designed to be rolled outward from the transverse center of the connector body over a flared lip portion of the connected piping abutted to the center step and a compressible colored ring tube portion circumscribing each pipe and abutted to the outer surface of the flared lip portions of the connected piping. A polymer clamp structure is designed to circumscribe the center step. An interior wedge portion of the clamp structure is designed to wedge between and abut the parallelly oriented proximal and distal capture fingers and to sustain transversely inward vectored force against the center step and longitudinally outward vectored force against the capture fingers from force exerted by a clamp member tightened around the diameter of the clamp structure.
[0006] In one embodiment of the disclosed tube connector, at least one cutaway portion of each capture finger is designed to permit viewing the colored ring within an interior portion of the given capture finger when the given capture finger has been rolled outward over its section of the lip portion of connected piping and colored ring. The compressible colored ring tube portion, when viewable through the cutaway portion of each capture finger, indicates a successful closure. In some embodiments of the disclosed tube connector, the compressible colored ring tube portion is a contrasting color from one or more of a group of green, yellow, orange, turquoise, light blue, and white.
[0007] In some embodiments of the disclosed tube connector, the proximal end and the distal end of the connector body are substantially equidistant from the actual transverse center of the connector body.
[0008] In some embodiments of the disclosed tube connector, the connecter body has the center step, a first proximal step of the at least one proximal step circumscribed by two parallelly oriented O-rings, and a first distal step of the at least one distal step circumscribed by two parallelly oriented O-rings.
[0009] In some embodiments of the disclosed tube connector, the connecter body has the center step, a second proximal step extending from the first proximal step and having the proximal end of the connector body, and a second distal step extending from the first distal step and having the distal end of the connector body.
[0010] In some embodiments of the disclosed tube connector, an outer groove portion of the polymer and radially collapsible clamp structure is designed to be circumscribed by and secured by a screw clamp.
[0011] In some embodiments of the disclosed tube connector, the tube connector is designed to be, upon installation, more than 85% interior to the connected pipe members.
[0012] In some embodiment of the disclosed tube connector, the center step defines the functional transverse center and the actual transverse center of the tube connector.
[0013] In inventive concept, to include the system and its corresponding method, now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description, and any preferred and/or particular embodiments specifically discussed or otherwise disclosed. Inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration only and so that this disclosure will be thorough, complete, and will fully convey the full scope of the inventive concepts to those skilled in the art.

DETAILED DESCRIPTION
[0002] Following are more detailed descriptions of various related concepts related to, and embodiments of, methods and apparatus according to the present disclosure. It should be appreciated that various aspects of the subject matter introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the subject matter is not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.
[0003] FIGS. 1-20 illustrate a disclosed representative tube connector system 10 that has a substantially cylindrical connector body 100 with a proximal end 101 and a distal end 109. Further, the tube connector 10 may be made through injection molding, though other manufacturing methods may be used. A through-passage 120 is open through the connector body 100 from the proximal end 101 to the distal end 109 and circumscribing a longitudinal center 105 of the connector body 100. Present is a stepped outer surface 110 of the connector body 100 wherein a center step 115 defines the functional transverse center 125 and the greatest diameter of the connector body 100. At least one proximal step 111 and at least one distal step 119 of lesser diameter extend longitudinally from the center step 115 and terminate respectively at the proximal end 101 and distal end 109. The functional transverse center 125 of the connector body 100 is a portion of the connector body 100 that is between connected pipes and may also be the actual transverse center 125 of the connector body 100 between the proximal end 101 and the distal end 109 of the connector body 100. The center step 115 is designed to be abutted by the open ends of two connected pipes, the connected pipes of a lesser diameter than the center step 115, one pipe circumscribing the at least one proximal step 111 and the other pipe circumscribing the at least one distal step 119, the through-passage 120 of the connector body 100 creating a pathway for liquid from one pipe to the other.
[0004] FIGS. 1-20 further illustrate at least one each O-ring seal member 130 disposed partially within connector grooved portions 135 circumscribing the outer surface 103 of the connector body 100 on at least one proximal step 111 and at least one distal step 119 extended from the center step 115, the O-ring seal members 130 designed to abut, be circumscribed by, and be partially compressed toward the longitudinal center 105 by the inner surface of connected piping to create 360-degree seals. Parallelly oriented proximal capture fingers 141 and distal capture fingers 149 circumscribe the center step 115 longitudinally apart from the functional transverse center 125 of the connector body 100, the capture fingers 141, 149 designed to be operably malleable enough to be rolled outward from the transverse center 125 of the connector body 100 over a flared lip portion 152 of the connected piping, the flared lip portion 152 of the connected piping labeled in this disclosure for illustration though apart from the inventive concept as a portion of the connecting piping, abutted to the center step 115 and a compressible colored ring tube portion 350, as initially illustrated in FIG. 3, circumscribing each pipe and abutted to the outer surface of the flared lip portions 152 of the connected piping. [0005] FIGS. 1-20 further illustrate views of the tube connector system 10 with the addition of, as initially illustrated in FIGS. 5-14 and 17, a polymer clamp structure 560 designed to circumscribe the center step 115. An interior wedge portion 565 of the clamp structure 560 is designed to wedge between and abut the parallelly oriented proximal capture fingers 141 and distal capture fingers 149 and to sustain transversely inward vectored force against the center step 115 and longitudinally outward vectored force against the capture fingers 141, 149 from force exerted by a clamp member 568 tightened around the diameter of the clamp structure 560.
[0006] FIGS. 1-20 further illustrate that in one representative embodiment of the disclosed tube connector system 10, at least one cutaway portion 145 of each capture finger 141, 149 is designed to permit viewing the colored ring tube portion 350 within an interior portion of the given capture finger 141, 149 when the given capture finger 141, 149 has been rolled outward over its section of the lip portion 152 of connected piping and colored ring tube portion 350. The compressible colored ring tube portion 350, when viewable through the cutaway portion 145 of each capture finger 141, 149 indicates a successful closure. In the representative embodiment of the disclosed tube connector system 10, the compressible colored ring tube portion 350 is a contrasting color from one or more of a group of green, yellow, orange, turquoise, light blue and white. A contrasting color is a color that makes it easy for a person to see that color because of at least one or more of its differences, such as white against black, and brightness, such as viewing fluorescent green.
[0007] FIGS. 1-20 further illustrate that in one representative embodiment of the disclosed tube connector system 10, the proximal end 101 and the distal end 109 of the connector body 100 are substantially equidistant from the actual transverse center 125 of the connector body 100. Some other embodiments of the tube connector system 10 may be asymmetrical where the transverse center 125 is functional instead of actual. In the representative embodiment, the transverse center 125 is both actual and functional.
[0008] FIGS. 1-20 further illustrate that in one representative embodiment of the disclosed tube connector 10, the connecter body 100 has the center step 115, a first proximal step 111A of the at least one proximal step 111 circumscribed by two parallelly oriented O- rings, and a first distal step 119A of the at least one first distal step 119 circumscribed by two parallelly oriented O-rings 130. The disclosed tube connector system 10, inclusive of the connector fingers 141, 149, may be at least one or more of polymer and metal, and may have components where some are polymer and some are metal.

[0010] FIGS. 1-20 further illustrate that in one representative embodiment of the disclosed tube connector system 10, the polymer clamp structure 560 has radially collapsible flexible extenders 563. In one representative embodiment of the disclosed tube connector system 10, an outer groove portion 567 of the polymer and radially collapsible clamp structure 560 is adapted to be circumscribed by and secured by a screw clamp 569. Other clamp types may be used, to include universal locking systems, lock clamps, finger locks, ties such as zip ties, crimping locks, and other locks known to those skilled in the art to secure tubes to piping. [0011] FIGS. 1-20 further illustrate that in one representative embodiment of the disclosed tube connector system 10, the connector body 100 is adapted to be, upon installation, more than 85% interior to the connected pipe members, thereby affording further compactness, burst resistance, and less chance for debris collection.
