DETAILED DESCRIPTION

(15) The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

(16) With reference to FIGS. 1-4, a socket assembly 10 is illustrated. The socket assembly 10 includes a frame 14, an input member 18, an output member 22, a first transfer member (e.g., first shaft 26), and a second transfer member (e.g., second shaft 30). The socket assembly 10 can be constructed in any suitable manner, including assembly from separate parts or 3d printed in its assembled state. In FIG. 1, the socket assembly 10 is illustrated with a line nut assembly 34 that includes a nut 38 and a conduit 42. The nut 38 can be a hex nut, as shown, or have another external shape configured to be engaged by the output member 22. The nut 38 is configured to be threaded onto a mating fluid connector (not shown, e.g., a fluid port or a mating connector of a corresponding second conduit). The mating fluid connector (not shown) has external threads configured to mate with the internal threads (not specifically shown) of the nut 38. The top of the nut 38 defines a nut aperture 46 coaxial with a rotational axis 50 of the nut 38.

(17) The conduit 42 is a fluid conduit, such as a rigid pipe or a flexible hose for example. The conduit 42 is hollow such that a fluid (e.g., a liquid or a gas) can flow through it. One end of the conduit 42 extends through the nut aperture 46 and the nut is configured to secure the conduit 42 to the mating connector (not shown) so that the conduit 42 is in fluid communication with the flow path of the mating connector (not shown). In the example provided, the conduit 42 is a rigid pipe that has a proximal portion 54 that extends coaxially from the end by a first distance and is coupled to a distal portion 58 by a bend portion 62. In the example provided, the bend portion 62 is a 90 degree elbow such that the distal portion 58 extends therefrom at perpendicular angle relative to the rotational axis 50, though the bend portion 62 can be configured at other angles.

(18) Referring to FIG. 2, the frame 14 includes a top housing 110, a bottom housing 114, and a connecting body 118. It is understood that the frame 14 shown in FIGS. 1 and 2 is symmetrical across the plane used for the cross-section of FIG. 2. The top housing 110 forms a shell that defines an input cavity 122 and a pair of first recesses 126 (only one of which is shown in FIG. 2). In the example provided, the input cavity 122 is a cylindrical cavity disposed coaxially about the axis 50. The first recesses 126 are open to the input cavity 122 and extend radially outward of the input cavity 122. The input cavity 122 is open through the top of the top housing 110.

(19) The bottom housing 114 is spaced apart from the top housing 110 along the axis 50 and forms a shell that defines an output cavity 130 and a pair of second recesses 134 (only one of which is shown in FIG. 2). In the example provided, the output cavity 130 is a cylindrical cavity disposed coaxially about the axis 50. The second recesses 134 are open to the output cavity 130 and extend radially outward of the output cavity 130. The output cavity 130 is open through the top and bottom of the bottom housing 114 via apertures 138 and 142, which are respectively defined by the top and bottom walls of the bottom housing 114. The output cavity 130 extends radially outward of the apertures 138, 142. In the example provided, the apertures 138, 142 are cylindrical and the same size, though other configurations can be used. The aperture 142 through the bottom wall is large enough to receive the nut 38 (FIG. 1) therethrough. In an alternative configuration, the aperture 138 through the top wall of the bottom housing 114 can be a different shape and/or can be smaller than the aperture 142, while still being large enough to receive the conduit 42 (FIG. 1) therethrough.

(20) The bottom housing 114 also defines a slot 146 open through a side of the bottom housing 114 and extending fully through the one side of the bottom housing 114. In other words, the slot 146 is open in the radial direction to permit movement of the conduit 42 in the radial direction from an exterior of the bottom housing 114 into the output cavity 130 and the slot 146 is open in the axial direction through the top and bottom walls of the bottom housing 114. Thus, the bottom housing 114 has a generally “C” shape or a discontinuous annular shape where the slot 146 forms the discontinuity in the annular shape.

(21) The connecting body 118 extends axially between the top housing 110 and the bottom housing 114 to connect the two housings 110, 114 and rigidly support them spaced axially apart. The connecting body 118, the top housing 110, and the bottom housing 114 cooperate to define a conduit space 150 configured to receive the conduit 42 between the top and bottom housings 110, 114. The conduit space 150 is open to the output cavity 130 through the aperture 138 and open through the same side of the socket assembly 10 as the slot 146 to allow the conduit 42 to bend off the axis 50 and away from the socket assembly 10. In the example provided, the connecting body 118 is a discontinuous annular shape such that the connecting body 118 extends between the top and bottom housings 110, 114 along a side of the socket assembly 10 that is opposite the slot 146. In the example provided, the connecting body 118 defines a pair of shaft bores 154 (only one of which is shown in FIG. 2) that generally connect the input cavity 122 to the output cavity 130. Each shaft bore 154 connects one of the first recesses 126 to one of the second recesses 134.

(22) Referring to FIGS. 3 and 4, the input member 18 includes a tool recess or aperture 210, a cylinder 214, and an input gear 218. In the example provided, the tool aperture 210 is defined by a cylindrical boss 222 that extends coaxially from the cylinder 214. The tool aperture 210 has a predefined shape that is configured to receive and engage with a mating predefined shape of a corresponding tool (not shown; e.g., a square head of a ratchet wrench or socket driver). Alternatively, the boss 222 can have an exterior surface of a predefined shape configured to be received in a mating interior feature of the tool (not shown). In the example provided, the boss 222 extends through an aperture 226 (FIG. 2) in the top wall of the top housing 110 (FIG. 2).

(23) The cylinder 214 is coaxial with the axis 50 and is disposed within the input cavity 122 (FIG. 2) and configured to rotate relative to the top housing 110 (FIG. 2). While not specifically shown, one or more bearings can optionally support the input member 18 for rotation within the top housing 110 (FIG. 2). The input gear 218 is coupled to the cylinder 214 for rotation therewith about the axis 50 and is coaxial with the axis 50. The input gear 218 is located on an opposite axial end of the cylinder 214 as the boss 222. The input gear 218 defines a plurality of teeth. In the example provided, the teeth of the input gear 218 are external spur gear teeth, though other configurations can be used. In the example provided, the input gear 218 has an outermost diameter that is less than the diameter of the cylinder.

(24) The output member 22 includes a socket head 230 and an output gear 234. The socket head 230 is disposed coaxially about the axis 50 and includes a plurality of interior facing walls 238 arranged in a predetermined shape to define a socket cavity 242. The walls 238 are configured to mate with the exterior surface of the nut 38 (FIG. 1) to impart torque thereto. In the example provided, the walls 238 of the socket cavity 242 are arranged in a hexagonal pattern about the axis 50, though other shapes can be used depending on the mating nut 38 (FIG. 1). The socket cavity 242 is open through the top and bottom ends of the output member 22 via apertures 246 and 250. In the example provided, the apertures 246, 250 are the same size and shape as the socket cavity 242. In an alternative configuration, the aperture 246 through the top of the output member 22 can be a different shape (e.g., cylindrical) and can be smaller than the socket cavity 242, while still being large enough to receive the conduit 42 (FIG. 1) therethrough.

(25) The output gear 234 is coupled to the socket head 230 for rotation therewith about the axis 50. The output gear 234 includes a plurality of teeth disposed about the axis 50. In the example provided, the teeth are external spur gear teeth, though other configurations can be used. In the example provided, the teeth are formed about the perimeter of the socket head 230, but are configured to have a maximum diameter that is less than or equal to the diameter of the cylindrical outer surface 254 of the socket head 230.

(26) The output member 22 also defines a slot 258 open through a side of the output member 22 and extending fully through the one side of the output member 22 (i.e., through the socket head 230 and the output gear 234). In other words, the slot 258 is open in the radial direction to permit movement of the conduit 42 (FIG. 1) in the radial direction from an exterior of the output member 22 into the socket cavity 242 and the slot 258 is open in the axial direction through the top and bottom of the output member 22. Thus, the output member 22 has a generally “C” shape or a discontinuous annular shape where the slot 258 forms the discontinuity in the annular shape, similar to the bottom housing 114.

(27) The output member 22 is coaxial with the axis 50 and disposed within the output cavity 130 (FIG. 2) and configured to rotate relative to the bottom housing 114 (FIG. 2). While not specifically shown, one or more bearings can optionally support the output member 22 for rotation within the bottom housing 114 (FIG. 2). The slot 258 of the output member 22 is configured to align with the slot 146 of the bottom housing 114 when the output member 22 is in a first rotational position, shown in FIG. 1.

(28) The first and second shaft 26, 30 each includes an input transfer gear 262 and an output transfer gear 266. The input transfer gears 262 are disposed at one end of their corresponding shaft 26, 30 and meshingly engaged with the input gear 218, while the output transfer gears 266 are disposed at the opposite end of the corresponding shaft 26, 30 and meshingly engaged with the output gear 234. In the example provided, the input transfer gears 262 are disposed partially within the first recesses 126 and the output transfer gears 266 are disposed partially within the second recesses 134. Each of the shafts 26, 30 extends axially through a corresponding one of the shaft bores 154 and is rotatable relative to the frame 14. While not specifically shown, the shafts 26, 30 can be optionally supported for rotation relative to the frame 14 by bearings. In an alternative configuration, not specifically shown, the connecting body be arranged such that it does not include the shaft bores 154 and the shafts 26, 30 extend through the bottom of the top housing 110 and the top of the bottom housing 114, but are external to the connecting body 118.

(29) Referring to FIGS. 1-3, the socket assembly 10 is operated by first aligning the slots 146, 258, then moving the socket assembly 10 so that the proximal portion 54 of the conduit 42 is moved through the slots 146, 258 and into the socket cavity 242. The socket assembly 10 is then moved axially toward the nut 38 until the nut is received in the socket cavity 242, as shown in FIG. 1. The tool (not shown) is attached to the tool aperture 210 and operated to drive the rotation of the output member 22 and rotation of the nut 38.

(30) In an alternative construction, the socket assembly 10 can have a variable gear ratio between the input member 18 and the output member 22. In one such configuration, schematically shown in FIG. 5, the input member 18 includes a first input gear 218a and a second input gear 218b axially adjacent to each other. The first and second input gears 218a and 218b are similar to the input gear 218 (FIGS. 3 and 4) and have a similar diameter to each other, but different numbers of teeth relative to each other. The input member 18 and the frame 14 (FIGS. 1 and 2) are configured to permit the input member 18 to move axially relative to the shafts 26, 30 between a first position wherein the input transfer gears 262 engage the first input gear 218a and a second position wherein the input transfer gears 262 engage the second input gear 218b.

(31) Alternatively, as shown in FIG. 6, the shafts 26, 30 and the frame 14 (FIGS. 1 and 2) are configured to permit the shafts 26, 30 to move axially relative to the input member 18 between a first position wherein the input transfer gears 262 engage the first input gear 218a and a second position wherein the input transfer gears 262 engage the second input gear 218b. The output transfer gears 266 are configured to remain engaged with the output gear 234 when in the first and second positions.

(32) In yet another alternative construction, shown in FIG. 7, the shafts 26, 30 have two input transfer gears 262a and 262b axially adjacent to each other. The first and second input transfer gears 262a and 262b are similar to the input transfer gear 262 (FIGS. 3 and 4) and have a similar diameter to each other, but different numbers of teeth relative to each other. The shafts 26, 30 and the frame 14 (FIGS. 1 and 2) are configured to permit the shafts 26, 30 to move axially relative to the input member 18 between a first position wherein the first input transfer gears 262a engage the input gear 218 and a second position wherein the second input transfer gears engage 262b the input gear 218. The output transfer gears 266 are configured to remain engaged with the output gear 234 when in the first and second positions.

(33) Alternatively, the input member 18 and the frame 14 (FIGS. 1 and 2) can be configured to permit the input member 18 to move axially relative to the shafts 26, 30 between a first position wherein the first input transfer gears 262a engage the input gear 218 and a second position wherein the second input transfer gears 262b engage the input gear 218.

(34) In still alternative construction, shown in FIG. 8, the shafts 26, 30 have two output transfer gears 266a and 266b axially adjacent to each other. The first and second output transfer gears 266a and 266b are similar to the output transfer gear 266 (FIGS. 3 and 4) and have a similar diameter to each other, but different numbers of teeth relative to each other. The shafts 26, 30 and the frame 14 (FIGS. 1 and 2) are configured to permit the shafts 26, 30 to move axially relative to the output member 22 between a first position wherein the first output transfer gears 266a engage the output gear 234 and a second position wherein the second output transfer gears 266b engage the output gear 234. The input transfer gears 262 are configured to remain engaged with the input gear 218 when in the first and second positions.

(35) Alternatively, the output member 22 and the frame 14 (FIGS. 1 and 2) can be configured to permit the output member 22 to move axially relative to the shafts 26, 30 between a first position wherein the first output transfer gears 266a engage the output gear 234 and a second position wherein the second output transfer gears 266b engage the output gear 234.

(36) In another alternative configuration, shown in FIG. 9, the output member 22 includes a first output gear 234a and a second output gear 234b axially adjacent to each other. The first and second output gears 234a and 234b are similar to the output gear 234 (FIGS. 3 and 4) and have a similar diameter to each other, but different numbers of teeth relative to each other. The output member 22 and the frame 14 (FIGS. 1 and 2) is configured to permit the output member 22 to move axially relative to the shafts 26, 30 between a first position wherein the output transfer gears 266 engage the first output gear 234a and a second position wherein the output transfer gears 266 engage the second output gear 234b.

(37) Alternatively, the shafts 26, 30 and the frame 14 (FIGS. 1 and 2) can be configured to permit the shafts 26, 30 to move axially relative to the output member 22 between a first position wherein the output transfer gears 266 engage the first output gear 234a and a second position wherein the output transfer gears 266 engage the second output gear 234b. The input transfer gears 262 are configured to remain engaged with the input gear 218 when in the first and second positions.

(38) For any of the preceding configurations shown in FIGS. 5-9, the switching between first and second positions can be achieved by any suitable means, such as a lever or switch that can be actuated from the exterior of the frame 14 (FIGS. 1 and 2). The lever or switch can be manually moved by a user or the socket assembly 10 can be switched between the first and second positions via an actuator such as a solenoid for example. With reference to FIGS. 10-12, one non-limiting example of a manual switch is illustrated and identified with reference numeral 310. In the example provided, the switch 310 includes a body or plate 314 that is coupled to both shafts 26, 30 for common axial translation with the shafts 26, 30. The shafts 26, 30 are rotatable relative to the plate 314. The plate extends through an aperture 318 in the frame 14 to be accessible from the exterior of the frame 14. The example shown in FIGS. 10 and 11 can correspond to any of the configurations of FIGS. 6-9 where the shafts move relative to the frame 14. While not specifically shown, a similar switch can be attached to the input member 18 (FIGS. 5-7) or the output member 22 (FIG. 8 or 9) and extend exterior of the frame 14 in order to permit a user to axially move the input or output member 18 or 22 while still permitting rotation of the input or output member 18 or 22.

(39) The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
