The disclosure relates generally to connectors for fluid systems and vessels and more particularly to connectors for fluid systems that are quickly connectable and quickly disconnectable from each other.
Quick connect/disconnect adaptor systems, which are also referred to herein as quick connect/disconnect systems or as “QCD systems” are configured to facilitate the connection and disconnection of male and female connectors, particularly connectors used to connect a fluid conductor to a source of fluid. For instance, a house typically includes a sillcock, which is usually located at or near the foundation of the house. Oftentimes, this location can make it difficult to thread a hose to the sillcock, since the location can be difficult to access. QCD systems are used, for example, to reduce the difficulty in attaching a hose to the sillcock.
Typically, the QCD system includes a first component which screws onto the sillcock such that a threaded male portion of the sillcock mates with a threaded female portion of the first component. A second component of the QCD system is attached to the hose and often includes a threaded female portion which accepts a threaded male portion of the hose.
The first component and the second component, mate with one another, but typically not in a threaded fashion. Instead, the first component and the second component are coupled together through insertion of the second component into the first component where the two components are held together in watertight fashion by either a press-fit or by a partial rotation of one component with respect to the other component. The partial rotation of one component with the other acts to sealingly engage the first component to the second component to prevent leakage.
One issue encountered by users of QCD systems is that only the second component is connectable to the first component. Thus, when the first component is connected to the fluid source, the second component must be used, thereby preventing users from connecting non-QCD components to the fluid source. For this reason and/or other reasons, further developments in the area of QCD systems are desirable.
A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below.
Embodiments of the disclosure are related to quick connect/disconnect systems and methods for connecting and disconnecting fluid dispensing devices. The devices can be hoses, faucets, tubes, pipes, sprinklers, nozzles, wands, and other hose attachments. The system includes a main body which is connected to the source of fluid, such as water, and an adaptor, which is coupled to a delivery device, such as a hose.
According to one embodiment of the disclosure, a quick connect/disconnect (QCD) system includes a first component and a second component. The first component includes a first body defining a first fluid channel extending between a first end portion and a second end portion and defining a longitudinal axis, a first QCD coupling portion located at the first end portion, a first adaptor coupling portion located at the second end portion, and a first mating portion of a mating assembly operably connected to the first body. The second component includes a second body defining a second fluid channel extending between a third end portion and a fourth end portion, a first threaded coupling portion located at the third end portion, a second adaptor coupling portion located between the third end portion and the fourth end portion, and a second mating portion of the mating assembly operably connected to the second body. The mating assembly is configured such that when the first mating portion and the second mating portion are mated, the first adaptor coupling portion is coupled with the second adaptor coupling portion.
According to another embodiment of the disclosure, a method of manipulating a quick connect/disconnect (QCD) system includes aligning a first end portion of a first component, the first component having a second end portion with a first QCD coupling portion, with a third end portion of a second component; and moving a threaded portion of the third end portion within a first body of the first component. The method further includes mating a first mating portion of a mating assembly with a second mating portion of the mating assembly. The first mating portion being operably connected to the first body and the second mating portion being operably connected to a second body of the second component. The method also includes coupling a first adaptor coupling portion located at the first end portion with a second adaptor coupling portion located between the third end portion and a fourth end portion of the second component.

The end portion 109 includes a threaded coupling portion 106 including internal threads, which are configured to mate with corresponding male threads as may be found on a sillcock, faucet, or spigot, for example. The end portion 107 includes another threaded coupling portion 108 including external threads configured to threadingly engage corresponding female threads, such as, the female threads on the female coupler of a hose, for example. The coupling portion 108 can be used in conditions where the quick connect/disconnect feature of the QCD system 100 is not being used and can be coupled directly to a female coupler, for instance. The coupling portion 108 can also be eliminated if desired.

The retaining ring 140 is configured to engage the locking tab 114 and, when rotated to the locked position, to hold the QCD component 104 to the adaptor component 102. Rotation of the retaining ring 140 also compresses the O-rings 116 and 118 at the body 115 against the cuff 110 to strengthen a watertight seal between adaptor component 102 and the QCD component 104. Furthermore, when the rotating ring 140 is in the locked position, the detent 155 on the disconnecting axial stop 149 engages the detent 167 on the locking tab 114, and the detent 151 engages the first end 176 of the locking tab 114 to releasably retain the retaining ring 140 in the locked position.
The QCD component 800 further includes a QCD coupling portion 820 and a threaded coupling portion 824. The QCD coupling portion 820 is located at the first end portion 808 and is identical to the QCD coupling portion 137 of the QCD component 104. Accordingly, the QCD coupling portion 820 includes a sealing member 811, a spacer 812, and an o-ring 814 that correspond to the sealing member 130, the spacer 128, and the o-ring 127 of the QCD component 104 (see
The threaded coupling portion 824 is located at the second end portion 812 and is identical to the threaded coupling portion 106 of the adaptor component 102. Accordingly, the threaded coupling portion 824 is configured for threaded engagement to the threaded coupling portion 108 of the adaptor component 102.
In operation, the QCD system 100 is manipulated, as described below. First, the adaptor component 102 is connected to a source of fluid, such as a sillcock (not shown). The adaptor component 102 is a versatile unit that makes available to the user both the threaded coupling portion 108 and the cuff 110 of the mating assembly 117. Accordingly, with the adaptor component 102 connected to the sillcock, the female threaded coupling portion of a standard hose (for example) can be connected to the threaded coupling portion 108 or the QCD component 104 can be connected to the cuff 110. Thus, the user is able to easily use accessories, tools, and components that connect to either the coupling portion 108 or the QCD coupling portion 137 of the QCD component 104.
To use the QCD component 104 with the adaptor component 102, first the end portion 131 of the QCD component 104 is aligned with the end portion 107 of the adaptor component 102 such that the longitudinal axis 119 of the QCD component 104 is coaxial with the longitudinal axis 138 of the adaptor component 102. Also, in this configuration the fluid channel 125 of the QCD component 104 is aligned with the fluid channel 113 of the adaptor component 102.
Next, the QCD component 104 is advanced toward the adaptor component 102 so that the threaded coupling portion 108 is moved to a position within the body 115 of the QCD component 104. When the threaded coupling portion 108 is positioned within the body 115, the threaded coupling portion 108 is located between the end portion 129 and the end portion 131 of the QCD component 104. Then, the QCD component 104 is further advanced toward the adaptor component 102 so that the adaptor coupling portion 139 of the QCD component 104 is coupled to the adaptor coupling portion 121 of the adaptor component 102, and the QCD component 104 becomes rotationally fixed relative to the adaptor component 102. The QCD component 104 may have to be rotated with respect to the adaptor component 102 to enable the adaptor coupling portion 121 to couple to the adaptor coupling portion 139.
At substantially the same time (simultaneously) as the adaptor coupling portion 121 is coupled with the adaptor coupling portion 139, the mating portion (i.e. the cuff 110) is mated with the mating portion (i.e. the retaining ring 140) of the mating assembly 117. Mating the portions 110, 140 of the mating assembly 117 includes positioning the locking tabs 114 axially between the axial stops 147 and the axial stops 149 of the retaining ring 140. In particular, the QCD component 104 is moved toward the adaptor component 102 until the axial stops 147 abut the locking tabs 114. Accordingly, the mating assembly 117 is configured such that when the cuff 110 and the retaining ring 140 are mated, the adaptor coupling portion 121 is coupled with the adaptor coupling portion 139 and the end portion 108 is positioned between the end portion 129 and the end portion 131.
After the mating portions 110, 140 are mated, the retaining ring 140 is rotated to lock the QCD component 104 to the adaptor component 102. Rotation of the retaining ring 140 is stopped when the rotational stops 168 abut the end portions 180 of the locking tabs 114 of the cuff 110.
Another embodiment of the retaining ring 500 is shown isolation in
The QCD component 900 further includes a QCD coupling portion 920 and a threaded coupling portion 924. The QCD coupling portion 920 is located at the first end portion 908 and is identical to the QCD coupling portion 137 of the QCD component 104. Accordingly, the QCD coupling portion 920 includes a sealing member 911, a spacer 912, and an o-ring 914 that correspond to the sealing member 130, the spacer 128, and the o-ring 127 of the QCD component 104 (see
The threaded coupling portion 924 is located at the second end portion 912 and is identical to the threaded coupling portion 106 of the adaptor component 102. Accordingly, the threaded coupling portion 924 is configured for threaded engagement to the threaded coupling portion 108 of the adaptor component 102.
