DETAILED DESCRIPTION

[0045] For purposes of this description, certain aspects, advantages, and novel features of examples of this disclosure are described herein. The disclosed methods, apparatus, and systems should not be construed as being limiting in any way. Instead, the present disclosure is directed toward all novel and nonobvious features and aspects of the various disclosed examples, alone and in various combinations and sub-combinations with one another. The methods, apparatus, and systems are not limited to any specific aspect or feature or combination thereof, nor do the disclosed examples require that any one or more specific advantages be present or problems be solved.

[0046] Although the operations of some of the disclosed examples are described in a particular, sequential order for convenient presentation, it should be understood that this manner of description encompasses rearrangement, unless a particular ordering is required by specific language set forth below. For example, operations described sequentially may in some cases be rearranged or performed concurrently. Moreover, for the sake of simplicity, the attached figures may not show the various ways in which the disclosed methods can be used in conjunction with other methods. Additionally, the description sometimes uses terms like provide or achieve to describe the disclosed methods. These terms are high-level abstractions of the actual operations that are performed. The actual operations that correspond to these terms may vary depending on the particular implementation and are readily discernible by one of ordinary skill in the art.

[0047] As used in this application and in the claims, the singular forms a, an, and the include the plural forms unless the context clearly dictates otherwise. Additionally, the term includes means comprises. Further, the term coupled generally means physically, mechanically, chemically, magnetically, and/or electrically coupled or linked and does not exclude the presence of intermediate elements between the coupled or associated items absent specific contrary language.

[0048] FIG. 1 is a perspective view of a fitting installation apparatus 100, according to one example. The apparatus 100 can be used, for example, for installing a fitting into a fluid line. FIG. 1 depicts the apparatus 100 in a non-inserting state with a fitting omitted. FIG. 2 is a side view of the apparatus 100. FIG. 3 is a front view of the apparatus 100. FIG. 4 is a top view of the apparatus 100.

[0049] As shown in FIG. 1, the apparatus 100 comprises a main body 10 and a fitting installation member 20. The fitting installation member 20 is movably coupled to the main body 10. The main body 10 is configured to receive and support at least a portion of a fluid line. The fitting installation member 20 is configured to be inserted through a fitting, pierce the fluid line, and insert the fitting into the fluid line.

[0050] The fitting installation member 20 of the apparatus 100 comprises a handle 21, a shaft 22, and a tip portion 23. The handle 21 and the shaft 22 can be coupled in a thread manner, in other manner such as adhesive, bonding, etc., or they can be integrally formed as a single, unitary component.

[0051] The handle 21 of the fitting installation member 20 has a spherical shape, as shown in FIGS. 1-3. It shall be understood, however, that the handle 21 can have other shapes, such as ellipsoidal shape or cubic shape.

[0052] The shaft 22 of the fitting installation member 20 has an elongate shape and can be inserted into the main body 10, as further described below. The shape of the cross section of the shaft 22 is matched with the shape of the hole 15 in the guide member 11. As shown in FIG. 1, the cross section of the shaft 22 and the hole 15 on the guide member 11 both have a circular shape to be matched with each other. Accordingly, the shaft 22 can move axially and rotationally relative to the hole 15. Other shapes are also possible. For example, the cross section of the shaft 22 and the hole 15 in the guide member 11 can both have a non-circular shape (e.g., hexagonal shape, rectangular shape, etc.), to be matched with each other. Such non-circular configurations allow the shaft to move axially relative to the hole but restrict relative rotational movement between the shaft and the hole.

[0053] The tip portion 23 of the fitting installation member 20 is formed on the other end of the shaft 22 (i.e., the opposite side of the handle 21). The tip portion 23 is smaller than the shaft 22 in a first dimension, i.e., size in cross section. The shaft 22 and the tip portion 23 can both have a circular cross section, as is shown in FIG. 1 and FIG. 3. However, it should be understood that they can also have other shapes of cross section, such as a non-circular shape. In the example wherein both the shaft 22 and the tip portion 23 have circular cross section, the diameter of the tip portion 23 in its cross section is smaller than the diameter of the shaft 22 in its cross section. There can optionally be a transitional portion formed between the shaft 22 and the tip portion 23, having a diameter decreasing from the diameter of the shaft 22 to the diameter of the tip portion 23. This transitional portion can be omitted.

[0054] The tip portion 23 has an end 26 configured to pierce and be inserted into a fluid line. The end can optimally be a tapered and pointed end, or can have other shapes, to be suitable for piercing and/or being inserted into a fluid line.

[0055] As is shown in FIGS. 1-3, the main body 10 of the apparatus 100 comprises a guide member 11, a base 12, and two side walls 13. As mentioned above, the main body is configured for supporting a fluid line and for guiding the fitting installation member 20 relative to the fluid line.

[0056] The guide member 11 of the main body 10 is used to guide the movement of the shaft 22 of the fitting installation member 20. A hole 15 as described above is provided on the guide member 11, wherein the shaft 22 passes through the hole 15.

[0057] The base 12 of the main body 10 comprises a support element 19 having a groove 14 (which can also be referred to as a channel) formed therein. The support element 19 can be configured to support at least a portion of a fluid line. The groove 14 of the support element 19 is sized to accommodate at least a portion of the fluid line along a first direction, and the hole 15 and the shaft 22 passing through the guide member 11 are directed to extend in a second direction intersecting the groove 14. The first direction and the second direction can be perpendicular to each other, such that the shaft 22 and the fitting, which extend in the second direction, are perpendicular to the fluid line, which extend along the first direction.

[0058] The main body 10 can optionally comprise one or more side walls (e.g., two side walls 13) to connect the guide member 11 with the base 12. The guide member 11 can extend along the first direction between the two side walls 13. The guide member 11 can be integrally formed with the two side walls or can be coupled with the side walls 13 through, for example, adhesion or welding. Various other means for coupling can be used.

[0059] The side walls 13 and the base 12 are coupled, for example, by welding, or can be internally formed. The groove 14 is supported by the base 12 and extends along the first direction between the two side walls. In the example of FIGS. 1-3, the base 12 further comprises two protruding feet 16, to further support the groove 14 and the apparatus 100. In the example of FIGS. 1-3, the main body 10 further comprises a back supporting wall 17 that extends between and connects the two side walls 13, to provide additional support to the whole apparatus.

[0060] As is stated above, the side walls 13 can be integrally formed with the guide member 11, the base 12, and the back supporting wall 17. It should be understood that the guide member 11, the base 12, the side walls 13, and the back supporting wall 17 can be made of different materials and be separately produced.

[0061] FIG. 5 is an expanded and unfolded view of a base of a main body 10 of an apparatus for installing a fitting onto a fluid line according to one example of the invention.

[0062] As is shown in FIG. 5, the base 12, the side walls 13, the protruding feet 16, and the back supporting wall 17 are integrally formed as one piece. The one piece is then folded along the line L1 and line L2 to a 90 degree towards a same direction, to form the main body 10 together with the guide member 11 and the groove 14. The guide member 11 and the groove 14, as is shown in FIG. 1, has the same size with the back supporting wall 17 in the first direction, and are coupled to the one piece after it is folded. The guide member 11 and the groove 14 can be coupled to the one piece through adhesion, welding, or other appropriate approaches.

[0063] FIG. 6 is a perspective view of part of a fitting installation member 20 according to one example.

[0064] As is shown in FIG. 6, the shaft 20 of the fitting installation member 20 comprises a thread portion 24, in order to be in thread connection with the handle 21 (shown in FIG. 1) of the fitting installation member 20. It should be understood that the thread portion 24 can be omitted, and the handle 21 and the shaft 22 can be integrally formed.

[0065] In some instances, the tip portion 23 can comprise a stepped portion 25. As will be described below, during fitting installation process, the tip portion 23 would be inserted into the fitting. The stepped portion 25 can, for example, be used to adjust the length of the tip portion 23 and the shaft 22 that is inserted into the fitting. In some instances, the stepped portion can comprise threads. The threads can be configured to receive a nut or other component configured to adjust the effective working length of the tip portion 23.

[0066] FIG. 7 is a side view of an example of a fitting 30 that can be used with the apparatus 100. FIG. 8 is a section view of the fitting along the line 8-8 shown in FIG. 7.

[0067] As is shown in FIG. 7 and FIG. 8, the fitting 30 comprises a boss 31, a sleeve 32, and a nipple portion 33. The boss 31 is threaded connected to the sleeve 32 and is used to connect the sleeve to a branch fluid line after the fitting 30 is installed to a fluid line and after the fitting installation member 20 is removed from the fitting 30 and from the fluid line. The boss 31 fastens the sleeve 32 to the branch fluid line after the sleeve 32 is inserted into the branch fluid line through relative rotation between the boss 31 and the sleeve 32.

[0068] When installing the fitting 30 into a fluid line, the sleeve 32 of the fitting 30 surrounds the shaft 22 of the fitting installation member 20. Accordingly, the sleeve 32 is slightly larger than the shaft 20 in the first dimension, to accommodate part of the shaft 22 into the cavity 34 of the sleeve 32.

[0069] The nipple portion 33 of the fitting 30 is formed on the end of the sleeve 32, and a cavity 35 is also formed within the nipple portion 33. The cavity 35 formed in the nipple portion 33 is in communication with the cavity 34 formed in the sleeve 32. The nipple portion 33 is smaller than the sleeve 32 in the first dimension, and accordingly, the cavity 35 formed in the nipple portion 33 is smaller than the cavity 34 formed in the sleeve 32 in the first dimension. An annular wall 36 is formed between the cavity 34 in the sleeve 32 and the cavity 35 in the nipple portion 33, such that when the shaft 22 and the tip portion 23 fitting installation member 20 are inserted into the cavity 34 of the fitting 30, the end of the shaft 22 is pressed against the annular wall 36, and the tip portion 23 protrudes into the cavity 35 formed in the nipple portion 33 of the fitting 30. The tip portion 23 is larger than the nipple portion 33 in a second dimension, i.e., the length of the tip portion 23 L23 as shown in FIG. 3 is larger than the length of the nipple portion L33 as shown in FIG. 8, such that the tip portion 23 extends in the cavity 35 formed in the nipple portion 33 and protrudes out from nipple portion 33.

[0070] FIG. 9 is a perspective view of an apparatus for installing a fitting onto a fluid line, with fitting 30 installed, according to one example of the invention. FIG. 10 is a side view of the apparatus for installing the fitting 30 onto a fluid line in FIG. 9. FIG. 11 is a section view of the apparatus for installing the fitting 30 onto a fluid line along the Line 11 in FIG. 10.

[0071] As is shown in FIGS. 9-11, the fitting 30 is disposed on the fitting installation member 20 such that the shaft 22 is partially inserted into the cavity 34 of the fitting 30.

[0072] When installing the fitting 30 onto a fluid line, the shaft 22 first passes through the hole 15 formed on the guide member 11. Then the shaft 22 is then partially inserted into the cavity 34 of the fitting 30, such that the tip portion 23 extends through the nipple portion 33 of the fitting 30. A fluid line can be disposed within the groove 14 of the base 12. The fitting installation member 20 is further advanced together with the fitting 30 to the fluid line, and part of the tip portion 23 that protrudes out from the nipple portion 33 of the fitting 30 is inserted into the fluid line.

[0073] In the depicted example, the outer surface of the shaft 22 and the hole 15 are smooth such that the shaft 22 of the fitting installation member 20 can move axially and/or rotationally relative to the guide member 11 of the main body 10. In this manner, the shaft 22 is moved axially relative to the guide member 11 (and a fitting relative to a fluid line) by pushing or pulling the shaft 22 (e.g., via the handle).

[0074] In other examples, the shaft 22 and the hole 15 can comprise a threaded connection. In such instances, the shaft 22 can be rotated in a first direction (e.g., clockwise) relative to the guide member 11 to advance the shaft axially relative to the guide member 11 (and a fitting relative to a fluid line), and the shaft 22 can be rotated in a second direction (e.g., counterclockwise) relative to the guide member 11 to retract the shaft axially relative to the guide member 11. The thread connection between the shaft 22 and the guide member 11 may be advantageous for relatively thicker fluid lines, users with less strength, and/or when more precision is required. In some instances, the handle 21 of the shaft can comprise an elongate shape to provide leverage for rotating the shaft 22 relative to the guide member 11. In some instances, the handle 21 and the shaft can comprise a T shape.

[0075] As can be seen in FIG. 10 and FIG. 11, when the tip portion 23 of the fitting installation member 20 is inserted into the fluid line, as the fitting installation member 20 continues to move towards the groove 14 and the fluid line accommodated therein, the shaft 22 presses the annular wall 36 inside the fitting 30 and thus the fitting 30 continues to advance to the fluid line. Accordingly, the fluid line is pierced by the tip portion 23 and at least a part of the nipple portion 33 of the fitting 30 is inserted into fluid line with the tip portion 23 of the fitting installation member 20. When the fitting installation member 20 is withdrawn, a locking portion 37 (see FIGS. 7-8) of the fitting 30 prevents the fitting 30 from retracting out of the fluid line with the fitting installation member 20. As a result, the fitting 30 is coupled to the fluid line.

[0076] As is shown in FIGS. 9-11, a screw member 27 can be optionally formed on the shaft 22, to be in thread engagement with the thread portion 24 of the shaft 22. The screw member 27 is used to adjust the length of the shaft 22 that can pass through the hole 15 of the guide member 11. Thus, the length of the tip portion 23 that can be inserted in the groove 14 can be adjusted by the screw member 27. In other words, the screw member 27 acts as a stopper that restricts movement of the shaft 22 of the fitting installation member 20 relative to the guide member 11 of the main body 10.

[0077] Traditionally, a piercing tool is first inserted into the fluid line to form a hole therein, and then the fitting 30 is inserted into the hole. Accordingly traditional approach would be time consuming. By using the apparatus (e.g., the apparatus 100) and method disclosed herein, a user can install the fitting in a single step in which the fluid line is pierced and the fitting is secured to the fluid line. Additionally, the fluid line is supported, thereby reducing the likelihood of kinking. Further, the apparatus is safer than a typical tool because the piecing element is guided by the main body and guarded by the base. As yet another advantage, it is easier to place the fittings along the fluid line in a consistent and uniform manner. As such, the disclosed apparatus and methods save time and make it easier to install fitting into a fluid line.

[0078] FIG. 12A is a perspective view of an apparatus for installing a fitting onto a fluid line in a non-inserting state, according to one example of the application. FIG. 12B is a perspective view of the apparatus for installing a fitting onto a fluid line in FIG. 12A, in an inserted state, according to one example of the application. FIG. 12C is a perspective view of the apparatus for installing a fitting onto a fluid line in FIG. 12A, with the fitting in an inserted state and the fitting installation member removed from the fitting and from the fluid line, according to one example of the application. FIG. 12D is a perspective view of the apparatus for installing a fitting onto a fluid line in FIG. 12A, with the fitting in an inserted state and the apparatus removed, according to one example of the application.

[0079] As is shown in FIG. 12A, the fitting 30 is disposed on the fitting installation member 20 such that the shaft 22 is partially inserted into the cavity 34 of the fitting 30. The tip portion 23 of the fitting installation member 20 extends through the nipple portion 33 of the fitting 30. A fluid line 40 is disposed within the groove 14 of the base 12.

[0080] In FIG. 12B, the fitting installation member 20 is further advanced together with the fitting 30 to the fluid line, and part of the tip portion 23 that protrudes out from the nipple portion 33 of the fitting 30 is inserted into the fluid line. When the tip portion 23 of the fitting installation member 20 is inserted into the fluid line, as the fitting installation member 20 continues to move towards the groove 14 and the fluid line accommodated therein, the shaft 22 presses the annular wall 36 inside the fitting 30 and thus the fitting 30 continues to advance to the fluid line. Accordingly, the fluid line 40 is pierced by the tip portion 23 and at least a part of the nipple portion 33 of the fitting 30 is inserted into fluid line with the tip portion 23 of the fitting installation member 20.

[0081] In FIG. 12C, when the fitting installation member 20 is withdrawn, the fitting 30 is coupled to the fluid line 40.

[0082] In FIG. 12D, the fitting 30 continues to be coupled to the fluid line 40, and the apparatus 100 is removed from the fitting 30 and from the fluid line 40.

[0083] FIG. 13 is a side view of a portion of a fitting installation member 200 according to another example. The fitting installation member 200 functions similar to the fitting installation member 20 and can be used, for example with the apparatus 100 in lieu of the fitting installation member 20. One difference between the fitting installation member 200 and the fitting installation member 20 is that the fitting installation member 200 comprises an adjustable and/or replaceable tip portion 203.

[0084] The fitting installation member 200 comprises a shaft 202 and the replaceable tip portion 203.

[0085] In this example, an internal thread portion 208 is formed in a cavity 209 of the shaft 202, and a matching external thread portion 207 is formed on the tip portion 23. The tip portion 203 can be removed from the shaft 202, making replacement of the tip portion 203 to be easy.

[0086] In some examples, the tip portion 203 can comprise a flange member 205 extending radially outwardly relative to one or more other sections of the tip portion 203. The flange member can be configured to contact in interior shoulder of a fitting. In some examples, the flange member 205 movable relative to the tip portion (e.g., via a threaded connection). In this manner, the flange member can be used to adjust the effective length of the tip portion 203 that is inserted into a fitting.

[0087] FIG. 14 is s side view of a fitting 300 according to another example. FIG. 15 a section view of the fitting 300 along the line 15-15 in FIG. 14.

[0088] In this example, a valve 304 is formed on the fitting 300, and the valve 304 can lock or unlock the fluid path within the fitting 300 through rotation.

[0089] The disclosed methods, apparatus, and systems should not be construed as limiting in any way.
