- The field relates to a pivotable reel assembly, and in particular, for a pivotable reel assembly for spooling and unspooling a linear element.
- Linear elements (such as hoses for conducting fluid, electrical cords, air hoses, etc.) can be cumbersome and difficult to manage. Mechanical reels have been designed to help spool hoses onto a drum-like spool apparatus. Some conventional reels are manually operated, requiring the user to physically rotate the reel, or drum, to spool the hose. This can be tiresome and time-consuming for users, especially when the hose is of a substantial length. Moreover, conventional reels may be mounted to a fixed structure, such that the reel does not move in response to the user moving to a different location. Accordingly, there remains a continuing need for improved reel assemblies.
- In one embodiment, a reel assembly is disclosed. The reel assembly can include a frame comprising a base and an elongate mounting portion configured to pivot relative to the base about a pivot axis. The elongate mounting portion can comprise a proximal portion coupled with the base, a distal portion, and an intermediate portion between the proximal and distal portions. A spool drum can be connected with the intermediate portion of the elongate mounting portion. The spool drum can be configured to rotate about a rotational axis to spool and unspool a linear element, the rotational axis generally transverse to the pivot axis. A wheel can be connected to the distal portion of the elongate mounting portion and configured to roll about the pivot axis. The distal portion can position the wheel along a transverse axis that is generally transverse to the rotational axis and the pivot axis.
- In another embodiment, a reel assembly is disclosed. The reel assembly can include a frame and a spool drum connected with the frame. The spool drum can be configured to rotate about a rotational axis to spool and unspool a linear element. A spooling support can be coupled with the frame and offset from the spool drum along a transverse axis that is generally transverse to the rotational axis. The spooling support can be configured to translate along a spooling support axis generally parallel to and offset from the rotational axis. A motor can be operably connected with the spool drum to cause the spool drum to rotate about the rotational axis and can be operably connected with the spooling support to cause the spooling support to translate about the spooling support axis.

The elongate mounting portion can include a proximal portion coupled with the base, a distal portion, and an intermediate portion between the proximal and distal portions. A spool can be connected with the intermediate portion of the elongate mounting portion. The spool can be configured to rotate about a rotational axis to spool and unspool a linear element, with the rotational axis being generally transverse to the pivot axis. A wheel can be connected to the distal portion of the elongate mounting portion. The wheel can be configured to roll about the pivot axis. The distal portion of the mounting portion can position the wheel along a transverse axis that is generally transverse to the rotational axis and the pivot axis. The wheel can rotate about the transverse axis so as to cause the wheel to roll along a pathway disposed about the pivot axis.
- Beneficially, therefore, the reel assembly can pivot about a fixed pivot point, e.g., a pivot axis that does not translate during operation of the reel assembly. In various embodiments, the base of the reel assembly can be wider than the spool and can be dimensioned so as to resist overturning moments due to a user pulling the linear element and/or due to the weight of the reel assembly. In some embodiments, the base need not penetrate a support surface (e.g., the ground) during operation. Moreover, in various embodiments, the reel assembly can comprise conduits and connectors that enable the user to operate the linear element (e.g., a hose or cord) without tangling from an input line. Advantageously, the base of the reel assembly can comprise a connector having a connector axis aligned with the pivot axis. A conduit can connect to the connector, and can be routed around or through the frame to a second connector at an end of the spool drum. A conduit in the spool drum can provide communication with a proximal end of the linear element connected to the spool drum.
- In some embodiments, a motor can be operably connected with the spool to cause the spool to rotate about the rotational axis. A motor controller can be in electrical communication with the motor. The motor controller can be configured to transmit control signals to the motor to control the operation of the motor. In some embodiments, the reel assembly can include a spooling support coupled with the frame and offset from the spool along a transverse axis that is generally transverse to the rotational axis. The spooling support can be configured to translate along a spooling support axis generally parallel to and offset from the rotational axis. In various embodiments, the motor can be operably connected with the spooling support to cause the spooling support to translate about the spooling support axis.
- Beneficially, the embodiments disclosed herein can utilize a motor and motor controller to automatically spool and/or unspool a linear element, such as a hose, cord, etc. In various embodiments, for example, a controller can be configured to automatically shut off the supply of water to a water hose and can automatically spool (e.g., retract) the hose along the reel. In various embodiments, a controller can be configured to automatically unspool a water hose and begin supplying water to the hose. In some embodiments, the controller can comprise a timer that automatically starts and/or shuts off the supply of water after a predetermined time period. In some embodiments, the reel assembly can be controlled by a handheld remote control unit that communicates with the controller and/or motor controller over a wireless network.
- In some embodiments; the reel assembly can comprise a power switch that can be used to turn the reel assembly on and/or off when pressed by a user. The reel assembly can also comprise a wind-in switch that, when pressed by the user, automatically turns off the supply of fluid (e.g., liquid or gas) or current to the linear element (whether the linear element comprises a fluid hose or an electrical cord) and automatically winds in the linear element to spool the linear element about the spool. In various embodiments, when the reel assembly is turned OFF by the user, the battery may be preserved. In various embodiments, when the reel assembly is turned ON by the user and is inactive for a predetermined period of time, a controller can place the reel assembly into a sleep mode to conserve battery power.
- In the sleep mode, the controller may not communicate with external devices (such as a handheld remote control) over a communications network (such as a wireless network), which can significantly conserve battery power and lengthen battery life. When a user pulls the hose when the reel assembly is in sleep mode, the force induces a back electromotive force (EMF) in the motor, which sends an alert signal to the controller indicative of the back EMF. The controller can comprise processing electronics (which may be active processing components and/or passive electronic components) that can determine whether the user wishes to use the reel assembly based on the alert signal. If the alert signal indicates that the user wishes to use the reel assembly, then the controller can activate the reel assembly into an active state for operation by the user.
- Moreover, the embodiments disclosed herein can beneficially enable the user to pivot the reel assembly about a pivot axis that is non-parallel to (e.g., generally transverse to) the rotational axis of the spool. For example, the user may desire to direct a water hose (or other linear element) along a different direction or orientation. The embodiments disclosed herein can comprise a wheel offset from a pivot axis such that the user can pull, push, or otherwise move a distal portion of a frame so as to cause the reel assembly to pivot relative to the pivot axis. In some embodiments, the user can manually pivot the reel assembly about the pivot axis. In other embodiments, a motor can automatically cause the reel assembly to pivot. In addition, the embodiments disclosed herein can advantageously enable the linear element (e.g., hose, cord, etc.) to spool uniformly across a lateral width of the spool. For example, a spooling support can translate along a spooling support axis that is generally parallel to the rotational axis of the spool so as to evenly spool the linear element along the spool.

FIGS. 1-6 illustrate one embodiment of areel assembly 1. For example,FIG. 1 is a schematic rear perspective view of thereel assembly 1.FIG. 2 is a schematic front perspective view of thereel assembly 1 shown inFIG. 1 .FIG. 3 is a schematic top plan view of thereel assembly 1 shown inFIGS. 1 and 2 .FIG. 4 is a schematic front view of thereel assembly 1 shown inFIGS. 1-3 .FIG. 5 is a schematic left side view of thereel assembly 1 shown inFIGS. 1-4 .FIG. 6 is a schematic right side view of thereel assembly 1 shown inFIGS. 1-5 . The reel assembly can be used to support, reel and/or unreel a linear element that has a length larger (e.g., at least five times larger or at least ten times larger) than its width. For example, thereel assembly 1 shown inFIGS. 1-6 can be used to reel and/or unreel a hose having a lumen through which a fluid can flow, e.g., a water hose, an air hose, etc. In other arrangements, thereel assembly 1 can be used to spool and/or unspool an electrical cord or other linear element. - The
reel assembly 1 can comprise aframe 2 having abase 3 and an elongate mounting portion 4 extending from and/or otherwise coupled with thebase 3. Thebase 3 can comprise a relatively wide mounting surface that can rest on a support surface, such as the ground. In some embodiments, thebase 3 can be supported on the support surface (e.g., the ground) without any penetrating fasteners to secure thebase 3 to the support surface. In such arrangements, thebase 3 can be sufficiently wide so as to reduce overturning moments due to the weight of the components of theassembly 1. In other embodiments, thebase 3 may include one or a plurality of fasteners (such as stakes) to affix thebase 3 to the ground. In one embodiment, thebase 3 can have a generally circular shape. In other embodiments, thebase 3 can have other suitable shapes. - In the illustrated embodiment, the mounting portion 4 of the
frame 2 can comprise a pair of spaced apart,elongate arms proximal portion 5 to adistal portion 7. Although a pair ofarms proximal portion 5 can extend between and interconnect the pair ofarms base 3 such that the mounting portion 4 can pivot about a pivot axis P relative to thebase 3. Thus, theproximal portion 5 of theframe 2 can provide the pivoting connection to thebase 3, such that the proximal portion 5 (and hence the frame can pivot relative to thebase 3, with thebase 3 being generally stationary, during use. In the illustrated embodiment, theproximal portion 5 can be a planar piece with a length that is smaller than the outer effective diameter of thebase 3. In other embodiments, theproximal portion 5 can be about the same size and shape as the base, can be slightly smaller than thebase 3, or can be slightly larger than the base. - A
spool drum 8 can be mounted to anintermediate portion 6 of the mounting portion 4 disposed between the proximal 5 anddistal portions 7. For example, as shown inFIGS. 1 and 2 , thespool drum 8 can be rotatably coupled with theintermediate portion 6 such that thespool drum 8 can rotate about a rotational axis R that is non-parallel with (e.g., generally transverse to) the pivot axis P. In the illustrated embodiment, thespool drum 8 is disposed (e.g., offset) relative to the pivot axis P such that the pivot axis P and the rotational axis R do not intersect. Thespool drum 8 can comprise afirst end piece 9 and asecond end piece 10 spaced apart along the rotational axis R.A spooling surface 11 can be defined between the first andsecond end pieces spool drum 8 can rotate about the rotational axis R in a first direction (e.g., counterclockwise about the axis R as illustrated inFIG. 1 ) to spool the linear element (not shown) onto the spoolingsurface 11 of thespool drum 8. The spool can rotate about the rotational axis R in a second opposite direction (e.g., clockwise about the axis R as illustrated inFIG. 1 ) to unspool the linear element (not shown) from the spoolingsurface 11 of thespool drum 8. Theend pieces surface 11. - The
distal portion 7 of the mounting portion 4 can extend distally of theintermediate portion 6. In the illustrated embodiment, abend 18 in the mounting portion 4 can be defined at or near theintermediate portion 6 so as to angle thedistal portion 7 relative to theproximal portion 5. For example, as shown inFIG. 2 , thedistal portion 7 can comprise a segment angled generally along a transverse axis T which is non-parallel to (e.g., generally transverse to) the rotational axis R and the pivot axis P. Thedistal portion 7 of the mounting portion 4 can also comprise ahorizontal segment 16 coupled with avertical segment 17. The horizontal andvertical segments vertical segment 17 being smaller than a length of thehorizontal segment 16. Awheel 12 can be rotatably coupled with thevertical segment 17 of thedistal portion 7. In the illustrated embodiment, thewheel 12 comprises two rollers parallel to one another, but it should be appreciated that in other embodiments, thewheel 12 may comprise only a single roller. Thehorizontal segment 16, thevertical segment 17, and thewheel 12 can be dimensioned such that a lowermost portion of thewheel 12 contacts the support surface, e.g., the lowermost portion of thewheel 12 may be generally coplanar with a lowermost portion of thebase 3 in various arrangements. In one embodiment, thewheel 12 can contact and roll on the support surface (e.g., ground surface) as thereel assembly 1 is pivoted about the pivot axis P. In use, the pivot axis P may be generally fixed such that the pivot axis P does not translate along and/or tip relative to the support surface during use. For example, the weight of thereel assembly 1 and/or the width of thebase 3 may be configured to reduce or eliminate translation of thereel assembly 1 along the ground when subjected to normal pulling forces on the linear element. In another embodiment, thewheel 12 can contact and roll on a track (e.g., circular track) disposed or implemented on the support surface. - As shown in
FIGS. 2, 3, 5, and 6 , thewheel 12 can be disposed along the transverse axis T. For example, in the illustrated arrangement, thewheel 12 can be positioned such that the transverse axis T is positioned generally transverse to a major surface of thewheel 12. The pair ofend pieces wheel 12 disposed between the corresponding pair of planes. Thewheel 12 can rotate about the transverse axis T so as to cause thereel assembly 1 to roll along a path disposed about the pivot axis P. In some embodiments, the user can manually pull thedistal portion 7 of the frame 2 (for example, by pulling a linear element transverse to the axis T) to as to cause thewheel 12 to roll about (and the mounting portion 4 andspool drum 8 to pivot about) the pivot axis P. In other embodiments, a motor can be operated to automatically cause the mounting portion 4 to pivot about the pivot axis P andbase 3, e.g. based on a sensed pulling direction by the user. - In some embodiments, the
reel assembly 1 can advantageously include a spoolingsupport 13 coupled with theframe 2 and offset from thespool drum 8. The spoolingsupport 13 can cause the linear element to be spooled onto the spoolingsurface 11 of thespool drum 8 in a relatively uniform manner, which can reduce tangling and kinking of the linear element. For example, as shown inFIGS. 2, 3, 5, and 6 , the spoolingsupport 13 can be disposed along the transverse axis T. As shown inFIG. 2 , for example, the spoolingsupport 13 can comprise an opposing pair ofbearings support 13 can capture the linear element between thebearings reel assembly 1. The spoolingsupport 13 can be configured to translate along a spooling support axis S that is generally parallel to and offset from the rotational axis R. In some embodiments, a spoolingactuator 23 can be configured to cause the spoolingsupport 13 to translate along the spooling support axis S. For example, the spoolingactuator 23 can comprise a screw or threaded member that converts rotational movement to translational movement to move the spoolingsupport 13 along the axis S. - As shown in
FIGS. 2-5 , thereel assembly 1 can comprise amotor 19 that may be controlled by a motor controller (not shown). The motor controller can optionally be controlled via a remote control and/or one or more user interface controls (e.g., control buttons) on thereel assembly 1. Themotor 19 can comprise any suitable type of motor that converts an electrical input into mechanical motion. Themotor 19 can cause a motor shaft (not shown) to rotate, which in turn can cause afirst gear 20 to rotate (seeFIGS. 2-5 ). Rotation of thefirst gear 20 can cause a second gear 22 (FIG. 3 ) to rotate, which in turn can cause a third gear 21 (seeFIGS. 2 and 5 ) to rotate. As shown inFIGS. 2 and 5 , for example, thethird gear 21 can comprise a ring gear with teeth on an inner surface thereof. Rotation of the third gear 21 (induced by the motor 19) can cause thefirst end piece 9 and thespool drum 8 to rotate about the rotational axis R to cause the linear element to spool and/or unspool from the spoolingsurface 11. - In addition, as shown in
FIG. 3 , rotation of the second gear 22 (induced by the motor 19) can impart rotation to the spoolingactuator 23. For example, in the illustrated embodiment, thesecond gear 22 can impart rotation to the spoolingactuator 23 by way of a connectingelement 24. In the illustrated embodiment, the connectingelement 24 can comprise a belt that imparts rotation of the spoolingactuator 23 upon corresponding rotation of thesecond gear 22 and themotor 19. The belt can comprise a loop of material disposed about a pin or bearing of the spoolingactuator 23. Rotation of the spoolingactuator 23 can cause the spoolingsupport 13 to translate along the spooling support axis S. For example, as explained above, the spoolingactuator 23 can comprise a threaded connector that causes translation of the spoolingsupport 13 when rotated. Beneficially, therefore, themotor 19 can cause the linear element (not shown) to be automatically spooled and/or unspooled from thereel assembly 1, and can simultaneously or concurrently ensure that the linear element is uniformly distributed across the spoolingsurface 11. Thesame motor 19 can be used to cause the spooling and/or unspooling rotation of thespool drum 8 about the rotational axis R, and the translation of the spoolingsupport 13 along the axis S that is parallel to and offset from the rotational axis R. - As shown in
FIGS. 2-6 , thereel assembly 1 can further include acontroller 25 configured to receive and/or transmit electrical signals from and/or to a handheld remote control. Additional details of thecontroller 25 are provided below with respect toFIG. 18 . In some embodiments, thecontroller 25 can comprise a wireless controller having anantenna 49 in communication with processing electronics configured to process signals received from and/or transmitted to the handheld remote control. In operation, the user can activate the handheld remote control to actuate the motor controller andmotor 19 to cause the linear element to unspool from thespool drum 8. In embodiments that utilize a linear element comprising a liquid or gas hose, the user can interact with the handheld remote control to cause liquid or gas to flow through the linear element at predetermined or desired flow rates and/or pressures. In some embodiments, the user can interact with the handheld remote control to shut off the flow of liquid or gas through the linear element, and can cause the linear element to retract and/or spool about thespool drum 8. In some embodiments, a battery can also be coupled to theframe 2 so as to provide power to thecontroller 25 and/or themotor 19. It should be appreciated that, although thecontroller 25 is illustrated as being on the side of thevertical segment 17 nearer themotor 19, in other embodiments, thecontroller 25 can instead be disposed on the opposite side of thevertical segment 17, e.g., opposite themotor 19, Additional details of reel assemblies and their operation can be found throughout US 2012/0168003, US 2016/0003400, US 2014/0021283, US 2012/0267466, US 2013/0015284, US 2006/0266868, and US 2006/0000936, the entire contents of each of which are incorporated by reference herein in their entirety and for all purposes. It should be appreciated that the disclosed embodiments can be utilized in combination with any of the features and functionalities provided in the aforementioned disclosures. - Due to the pivoting of the
reel assembly 1 about the pivot axis P and the rotation of thereel 8 about the rotational axis R, it can be challenging to connect a conduit to thereel 8 for subsequent connection to the output linear element, e.g., a garden hose, an electrical cord, etc. Thereel assembly 1 shown inFIGS. 1-6 can connect to various source conduits that connect to a source. For example, in some embodiments, the source conduits can comprise tubular members connected to a water faucet for implementations in which the linear element comprises a water hose. In other embodiments, the source conduits can comprise cord segments that connect to an electrical outlet for implementations in which the linear element comprises an electrical cord. - As shown in
FIGS. 1-3 and 5-6 , thebase 3 can comprise afirst connector 14 configured to connect to a source conduit. As shown inFIG. 1 , for example, thefirst connector 14 can extend laterally from thebase 3 generally parallel to the support surface (e.g., the ground). In embodiments that utilize a linear element comprising a water hose, for example, thefirst connector 14 can comprise a male or female connection that interconnects with a tubular conduit configured to convey water. The tubular conduit can connect to a water faucet or other source of water. Thefirst connector 14 can communicate with an internal conduit (not shown) disposed within thebase 3. For example, the internal conduit can comprise one or more internal tubes, channels or hoses (for conveyance of water or gases one or more internal cables (for conveyance of electrical signals or power), or any other suitable type of conduit. The internal conduit can communicate with asecond connector 15, illustrated inFIGS. 1 and 3 . Thesecond connector 15 can provide fluidic or electrical communication between the conduit within thebase 3 and another conduit that connects to thespool drum 8 and ultimately the working linear element, as explained below in connection withFIGS. 7A-7C . -
FIG. 7A is a front perspective view of a reel assembly similar to the reel assembly ofFIGS. 1-6 .FIG. 7B is a rear perspective view of the reel assembly ofFIG. 7A .FIG. 7C illustrates a connector used to connect to a linear element. The features ofFIGS. 7A-7C may be the same as or generally similar to the features described above in connection withFIGS. 1-6 . As shown inFIGS. 7A-7B , thereel assembly 1 can comprise athird connector 27, which may be the same as or complementary to the first andsecond connectors conduit 28 can extend between thesecond connector 15 and thethird connector 27. For example, theconduit 28 can be routed around and/or through various portions of theframe 2. In the embodiment ofFIGS. 7A-7B , for example, theconduit 28 can extend from thesecond connector 15 on thebase 15, through anaperture 29 of theframe 2, and to thethird connector 27. In one embodiment, the conduit can be a tube made of a substantially rigid material (e.g., a plastic material such as polyvinyl chloride or PVC, a metal, etc.). Advantageously, theconnectors reel assembly 1 to rotate 360 degrees, for example without affecting the flow of water from the water source (e.g., water faucet) to the hose or linear material on thespool drum 8. Moreover, as shown inFIG. 7B , thesecond connector 15 can extend from thebase 3 and through theproximal portion 5, and can have a connector axis C along which fluid (for hoses) or electrical current (for cords) flows. The connector axis C can beneficially be aligned with the pivot axis P, which can enable fluidic or electrical communication to the spooled linear element without tangling when the user pivots thespool drum 8. - In some embodiments, the
conduit 28 can be a hose that extends between the second andthird connectors third connector 27, though the angular range of motion may be less than 360 degrees, such as less than 270 degrees, less than 180 degrees, etc. As shown inFIG. 7C , for example, thethird connector 27 can comprise amale connection 33 with external threads for connecting to a corresponding female connection of a water hose. An internal conduit (e.g., a fluid conduit, such as a hose, or an electrical conduit, such as a cord or cable) can be disposed within or on thespool drum 8. The internal conduit of thespool drum 8 can fluidly or electrically communicate with afourth connector 26 exposed on an outer surface of thespool drum 8, such as the spoolingsurface 11. Another conduit (not shown) can connect to a proximal end of the linear element, and the linear element can be wound or spooled around the spoolingsurface 11. In another embodiment, the proximal end of the linear element (e.g., hose) can connect to thefourth connector 26. -
FIG. 8 illustrates aspool drum 8 configured for use in various embodiments. Thespool drum 8 ofFIG. 8 can be the same as or substantially similar to thespool drum 8 described and illustrated in connection withFIGS. 1-7C , except, thespool drum 8 can comprise acontour 30 on an outer surface of theend pieces contour 30 can define a plurality of recesses separated by outwardly-projecting webs to define a mesh-shaped structure. -
FIG. 9 is a schematic side view of areel assembly 1 according to various embodiments. Thereel assembly 1 can be the same as or similar to thereel assembly 1 ofFIGS. 1-8 , except thereel assembly 1 can include ahousing 31 disposed about the reel. Thehousing 31 can comprise any suitable shape or design. In the illustrated embodiment, for example, thehousing 31 can define a frog-shaped profile. -

Unless otherwise noted, the components illustrated inFIGS. 10A-13B can be the same as or substantially similar to like-numbered components shown and described in connection withFIGS. 1-9 . The features shown inFIGS. 10A-13B can be readily combined with the features described in connection withFIGS. 1-9 . - For example, as shown in
FIGS. 10A-10C , alinear element 32 can be spooled about the spoolingsurface 11 of thespool drum 8. As explained above, in various embodiments, thelinear element 32 can comprise a fluid hose (e.g., a water hose, an air hose, etc.) or an electrical cord. Anoutlet 39 can be provided at a distal end of thelinear element 32, and thelinear element 32 can be disposed between thebearings outlet 39 positioned distal thebearings outlet 39 can comprise a nozzle or other connector when thelinear element 32 comprises a fluid hose. Theoutlet 39 can comprise an electrical connector when thelinear element 32 comprises an electrical cord. In addition,FIGS. 10A-10C illustrate abattery 34 that provides power to thecontroller 25. Thebattery 34 can comprise any suitable type of battery, such as a lithium ion battery. As explained below in connection withFIG. 18 , a power switch and/or a wind-in switch can be provided at or near thecontroller 25 to turn thereel assembly 1 ON or OFF, and/or to automatically wind in thelinear element 32. - In addition, as shown in
FIG. 10B , the base can have a lower surface that defines a lateral dimension L of thebase 3, such that the lower surface is to be supported by the support surface (e.g., the ground) during use of thereel assembly 1. Thespool drum 8 can have a width w along the rotational axis R defined by a distance between the outer surfaces of theend pieces spool drum 8 is less than the lateral dimension L of the base. Dimensioning thebase 3 to be wider than thespool drum 8 may provide improved stability for thereel assembly 1 when the user pulls on thelinear element 32. For example, when a user pulls thelinear element 32 along a direction tangent to the pivot axis P, the resulting moment may tend to cause thereel assembly 1 to overturn. Providing a sufficientlywide base 3 can assist in preventing such overturning moments. In various embodiments, the lateral dimension L of thebase 3 can be in a range of 9 inches to 24 inches, in a range of 9 inches to 18 inches, in a range of 10 inches to 15 inches, in a range of 9 inches to 13 inches, in a range of 9 inches to 12.5 inches, o rin a range of 10 inches to 12 inches, e.g., about 12 inches. In some embodiments, the width w of thespool drum 8 can be in a range of 3 inches to 8 inches or in a range of 4 inches to 8 inches. - Moreover, as shown in
FIGS. 12A-12B , additional components can be provided to assemble thereel assembly 1. For example, as shown inFIG. 12A , abushing 37 and asleeve 36 can be provided to connect theconduit 28 to thespool drum 8. As explained above, theconduit 28 can provide fluidic communication (when the linear element is a fluid hose, such as a water or air hose) or electrical communication (when the linear element is an electrical cord) between thesecond connector 15 and thethird connector 27. Internal conduit(s) of thespool drum 8 can provide fluidic or electrical communication to the linear element, e.g., by way of thefourth connector 26 shown inFIG. 7A . Anaxle shaft 38 can provide a smooth surface about which thespool drum 8 can rotate. Moreover, as shown inFIG. 12A , afastener 41 can connect thewheel 12 to thehorizontal segment 16. Thewheel 12 can rotate about thefastener 41. Furthermore, as shown inFIG. 12B , the spoolingsupport 13 can further comprise a spoolingguide 40. The spoolingguide 40 can comprise a rod along which thebearings FIG. 2 . Abushing 42 can connect to the spoolingactuator 23 to couple the spoolingactuator 23 to theframe 2. - Turning to
FIGS. 13A and 13B , as explained above, thefirst connector 14 can connect an input line (such as an input hose or cord) to one or more conduits in the base 3 (not shown). The one or more conduits in thebase 3 can connect to thesecond connector 15. Thesecond connector 15 may be coupled with thebase 3 and/or theproximal portion 5. For example, thesecond connector 15 can extend from thebase 3 through an aperture of theproximal portion 5. Thesecond connector 15 can have a connector axis C that provides communication (whether fluidic or electrical) vertically from thebase 3 and to theconduit 28 by way of a fitting 50. The connector axis C can be non-parallel relative to the rotational axis R and can be aligned with the pivot axis P. The fitting 50 can provide horizontal communication between thesecond connector 15 and theconduit 28. Further, as shown inFIGS. 13A, 13B , theconduit 28 can be angled so as to define afirst conduit segment 28 a and asecond conduit segment 28 b angled relative to thefirst conduit segment 28 a by way of an intervening bend. Theangled conduit 28 can provide fluidic or electrical communication to thethird connector 27 as explained herein. For example, as shown inFIG. 13B , and as explained above with respect toFIG. 7B , theconduit 28 can be disposed around or through theframe 2 so as to communicate with thethird connector 27. For example, theconduit 28 can extend through theaperture 29, which may comprise a hole or a slot in theframe 2. By orienting thesecond connector 15 along the pivot axis P and by routing theconduit 28 around or through theframe 2, the arrangement shown inFIGS. 13A-13B can beneficially enable the user to pivot theframe 2 andspool drum 8 about the pivot axis P without tangling the linear element during use. Thethird connector 27 can be configured to provide fluid or electrical communication with thelinear element 32 along a second connector axis parallel to the rotational axis R, e.g., to provide fluid or current through thespool drum 8. Theconduit 28 can therefore have a first end portion connected to thesecond connector 15 and a second end portion connected to thethird connector 27, with at least a portion of theconduit 28 extending non-parallel relative to the connector axis C. Theconduit 28 can be bent so as to pass through or around the mounting portion 4 of theframe 2 to provide fluid or electrical communication between theconnectors - The
proximal portion 5 of theframe 2 can be coupled with thebase 3 by way of an intervening disc bearing 36 (also illustrated inFIG. 12A ). As explained below in connection withFIGS. 14A-14C , the disc bearing 36 can provide a relatively hard, low friction surface that supports the pivotableproximal portion 5 of theframe 2. Although theproximal portion 5 is illustrated as having a polygonal (e.g., rectangular) profile, in other arrangements, theproximal portion 5 can be rounded. As theframe 2 pivots about the pivot axis P, a bottom surface of theproximal portion 5 can bear or press downwardly against an upper surface of thedisc bearing 36. The relatively low friction surface provided by the disc bearing 36 can enable smooth pivoting motions relative to thestationary base 3. Thedisc bearing 36 can comprise a sufficiently hard material that can bear the weight of thereel assembly 1 while also enabling smooth pivoting of thespool drum 8 about the pivot axis P. In various embodiments, the disc bearing 36 can comprise a polymer, such as Delrin® (acetal or polyoxymethylene), manufactured by DuPont™. In other embodiments, however, the disc bearing 36 can comprise one or a plurality of bearings or rollers that can provide smooth pivoting motions relative to thebase 3. - Moreover, as shown in
FIG. 13B , an upper surface of thebase 3 can comprise one or a plurality ofprojections 35 extending therefrom. Theprojections 35 can have a height h that is less than a thickness t of the disc bearing 36 (shown inFIG. 14C ). During operation, theframe 2 and/orspool drum 8 may tilt (e.g., due to user-applied forces to the linear element 32) so that the outer portions of theproximal portion 5 extending beyond thedisc hearing 36 may contact or rub against thebase 3, and/or may induce excessive pressure against regions of thedisc bearing 36. For example, if theframe 2 tilts excessively to one side, then the corresponding underlying region of the disc bearing 36 may experience excessive wear, and/or theframe 2 may experience increased friction during pivoting. - The
projections 35 extending from thebase 3 can beneficially provide support to theproximal portion 5 of theframe 2 if theframe 2 and/orspool drum 8 tilt during operation. The support provided by theprojections 35 can reduce the load on thedisc bearing 36 and can accordingly improve the pivoting motion of theframe 2. In some embodiments, the height h of theprojections 35 can be only slightly smaller than the thickness t of thedisc bearing 36. For example, in some embodiments, the height h of theprojections 35 can be shorter than a thickness t of the disc bearing 36 by an amount in a range of 1/16 inches to 1/64 inches, or in a range of 1/20 inches to 1/36 inches, e.g., about 1/32 inches. In some embodiments, the height h of theprojections 35 may be no more than 99% of the thickness t of thedisc bearing 36, no more than 95% of the thickness t of thedisc bearing 36, no more than 90% of the thickness t of thedisc bearing 36, no more than 75% of the thickness t of thedisc bearing 36, or no more than 50% of the thickness t of thedisc hearing 36. For example, the height h of theprojections 35 may be in a range of 50% to 99% of the thickness t of thedisc hearing 36, in a range of 75% to 99% of the thickness t of thedisc bearing 36, or in a range of 75% to 95% of the thickness t of thedisc bearing 36. In addition, a plurality ofprojections 35 are shown in an annular pattern around the pivot axis P; however, in other embodiments, only a single projection 35 (e.g., a ridge) can extend annularly around the pivot axis P. In various embodiments, theprojections 35 can be rounded so as to improve the support for thedisc bearing 36. -
FIG. 14A is a top perspective view of the disc bearing 36 shown inFIG. 13B .FIG. 14B is a top plan view of the disc bearing ofFIG. 14A .FIG. 14C is a schematic side sectional view of the disc bearing ofFIGS. 14A-14B . Thedisc bearing 36 can comprise anopening 45 through which components may extend to provide mechanical connection, fluid communication, and/or electrical communication between thebase 3 and theframe 2. For example, thesecond connector 15 can extend through theopening 45 to connect to theconduit 28 by way of the fitting 50. Other rotating shafts or components may also extend through theopening 45. - As shown in
FIGS. 14A-14C , the disc bearing 36 can comprise a plurality ofannular ridges 43 projecting upward and spaced apart by interveningannular grooves 44. In the illustrated embodiment, for example, the disc bearing 36 can comprise a firstouter ridge 43 a, asecond ridge 43 b, and a thirdinner ridge 43 c. A firstouter groove 44 a can be disposed between the firstouter ridge 43 a and thesecond ridge 43 b. A secondouter groove 44 b can be disposed between thesecond ridge 43 b and the thirdinner ridge 43 c. Beneficially, theannular ridges 43 can provide a low surface area (and hence low friction) bearing surface on which theproximal portion 5 of theframe 2 can pivot. For example, theannular ridges 43 can provide a bearing surface along which the mounting portion 4 of theframe 2 slides when the mounting portion 4 pivots about the pivot axis P. - Moreover, the use of
multiple grooves 44 can advantageously trap debris within thegroove 44 such that the debris does not increase the friction when theproximal portion 5 pivots relative to thedisc bearing 36. For example, debris (dirt, sand, dust, etc.) may enter thereel assembly 1 and may pass over or on top of the firstouter ridge 43 a. Such inwardly-moving debris can beneficially be trapped in the firstouter groove 44 a. For example, if debris passes on top of theridge 43 a, movement of theframe 2 and/or gravity may cause the debris to fall off theridge 43 a and into thegroove 44 a. Similarly, debris may pass over or on top of the thirdinner ridge 43 c, Such outwardly-moving debris can beneficially be trapped in the secondinner groove 44 b. Thus, thegrooves 44 can trap debris so as to provide a receptacle for debris that passes over the grooves, thereby reducing friction. Although a plurality ofridges 43 are shown inFIGS. 14A-14C , it should be appreciated that in other embodiments, only a single ridge may be provided. As explained above, the thickness t of thedisc bearing 36, as measured from an uppermost surface of the disc bearing 36 (e.g., a top surface of the ridges 43) to a lowermost surface of thedisc bearing 36, can be in a range of ⅛ inches to ½ inches, e.g., about ¼ inches. -
FIG. 15 is a schematic top plan view of areel assembly 1, according to another embodiment, Unless otherwise noted, components shown inFIG. 15 may be the same as or similar to like-numbered components shown inFIGS. 1-14C . For example, as with the above embodiments, theproximal portion 5 of theframe 2 can be pivotally connected to thebase 3, such that theframe 2 and thereel drum 8 can pivot about the pivot axis P. The pivot axis P can be relatively stationary during use. Further, thereel drum 8 can rotate about the rotational axis R, which can be transverse to the pivot axis P. - Unlike the embodiments shown above, however, the pivoting motion of the
frame 2 and reeldrum 8 about the pivot axis P can be provided by a pivoting engagement between thebase 3 and theproximal portion 5 of theframe 2. For example, as shown inFIG. 15 , theproximal portion 5 of theframe 2 may be similar in size and shape to thebase 3, such that theproximal portion 5 fits over thebase 3. Thus, as shown by the hidden lines ofFIG. 15 , theproximal portion 5 of theframe 2 is wider than theunderlying base 3 so as to obscure thebase 3 in the top view ofFIG. 15 , In other embodiments, however, theproximal portion 5 can be narrower than thebase 3. As shown inFIG. 15 , thebase 3 can comprise a channel 47 defining anouter channel wall 47 a and an inner channel wall 47 b. In the illustrated embodiment, a plurality ofrollers 46 can be provided side by side in the channel 47 in an annular arrangement about the pivot axis P. In various embodiments, therollers 46 can comprise ball bearings or other suitable rolling components. Theproximal portion 5 of theframe 2 can be disposed over therollers 46 such that, when the linear element is pulled by the user (e.g., in a direction tangent to the base 3), theframe 2 andspool drum 8 can freely pivot about the pivot axis P. Although a plurality ofrollers 46 are shown inFIG. 15 , in other embodiments, thespool drum 8 can connect to a wheel (similar to thewheel 12 shown herein) that can roll along the channel 47 in thebase 3. -
FIGS. 16A and 16B are schematic top plan views of abase 3 that incorporates pivotingbase extensions 48 for improved stability. As explained herein, it can be desirable to dimension thebase 3 such that thebase 3 can accommodate overturning moments due to external forces (e.g., a user pulling the linear element) and/or the weight of thereel assembly 1. However, the lateral dimension L may be limited by packaging constraints, user preferences, and other factors. For example, it can be important to dimension thebase 3 with the lateral dimension L sufficiently large so as to account for overturning moments, but small enough to fit within packaging constraints that may be set by the customer or another entity. Furthermore, the user may prefer that the lateral dimension L be small enough to store in small closets, etc. - Accordingly, in the embodiment of
FIGS. 16A-16B , thebase 3 can have a first stored profile as shown inFIG. 16A , and a second deployed profile as shown inFIG. 16B . In the stored profile ofFIG. 16A , theextensions 48 may be disposed under the body of thebase 3. To deploy thebase 3 to the deployed profile ofFIG. 16B , the user can rotate theextensions 48 outwardly about respective extension pivot axes r such that a proximal portion of eachextension 48 is connected with an outer periphery of thebase 3 at the respective extension pivot axis r, and a distal portion of eachextension 48 extends outwardly from the periphery of thebase 3. As shown in the deployed profile ofFIG. 16B , theextensions 48 can provide an increased footprint as compared with the stored profile ofFIG. 16A . Beneficially, the stored profile ofFIG. 16A can enable thebase 3 to fit within small packages and/or to be stored in small spaces. For example, in various embodiments, the stored profile can have a largest lateral dimension L in a range of 8 inches to 15 inches, or in a range of 10 inches to 15 inches e.g., about 12 inches. The deployed profile ofFIG. 16B can improve the stability of thebase 3 and its ability to withstand overturning moments, by increasing the footprint of thebase 3 during use. The largest lateral dimension of thebase 3 withextensions 48 extended outwardly inFIG. 16B can be in a range of 12 inches to 36 inches, in a range of 15 inches to 36 inches, or in a range of 15 inches to 24 inches. In the deployed profile, the largest lateral dimension can be measured as the maximum dimension measured between two outermost points of thebase 3 andextensions 48. -
FIGS. 17A and 17B are schematic top plan views of abase 3 that incorporates slidingbase extensions 48 for improved stability. Thebase 3 shown inFIGS. 17A-17B is generally similar to thebase 3 andextensions 48 shown inFIGS. 16A-16B , except inFIGS. 17A-17B , theextensions 48 are slideable relative to the body of thebase 3, as opposed to rotatable. For example, in the stored profile ofFIG. 17A , theextensions 48 are disposed underneath the body of thebase 3. The stored profile ofFIG. 17A can enable theassembly 1 to be packaged or stored within a compact footprint. To improve the stability of theassembly 1 during use, the user can slide theextensions 48 outwardly along a slider s. Thus, as with the embodiment ofFIGS. 16A-16B , the extensions of 48 ofFIGS. 17A-17B can improve the stability of the reel assembly while enabling packaging or storage within a smaller footprint. As withFIGS. 16A-16B , in the embodiment ofFIGS. 17A-17B , the stored profile can have a largest lateral dimension L in a range of 8 inches to 15 inches, or in a range of 10 inches to 15 inches e.g., about 12 inches. The deployed profile ofFIG. 16B can improve the stability of thebase 3 and its ability to withstand overturning moments, by increasing the footprint of thebase 3 during use. The largest lateral dimension of thebase 3 withextensions 48 extended outwardly inFIG. 16B can be in a range of 12 inches to 36 inches, in a range of 15 inches to 36 inches, or in a range of 15 inches to 24 inches. -
FIG. 18 is a schematic system diagram of a reel assembly, according to various embodiments. Unless otherwise noted, the components ofFIG. 18 may be the same as or generally similar to like-numbered components shown and described in connection withFIGS. 1-17B . For example, thereel assembly 1 can comprise acontroller 25 that includes processing electronics configured to control the operation of theassembly 1. Thecontroller 25 can comprise active integrated device dies such as processors that can be programmed to execute instructions stored on non-transitory computer readable storage media. Thecontroller 25 can also include passive circuit elements, such as resistors, capacitors, and inductors that cooperate to perform various functions. - As explained above, the battery 34 (such as a lithium ion battery) may provide electrical power to the
controller 25 and other components of the reel assembly such as themotor 19. Thecontroller 25 can comprise processing electronics that sends instructions to the motor to cause thespool drum 8 to rotate and/or the spoolingactuator 23 to translate to spool and/or unspool the linear element. For example, thecontroller 25 can send electrical signals to themotor 19 to drive the motor, which in turns imparts rotation to the gears 20-22, for example, by way of a motor shaft. - In some embodiments, the user can operate a handheld
remote control 55 to control the operation of thereel assembly 1. For example, as explained in the references appended hereto, the handheldremote control 55 can communicate with theantenna 49 of thereel assembly 1 over a wireless communications network. In addition, acontrol mechanism 58 may be switchably connected to the spool drum 8 (e.g., to the connectors and/or conduits coupled with the spool drum 8) and thelinear element 32. In embodiments in which thereel assembly 1 includes a fluid hose as thelinear element 32, thecontrol mechanism 58 can comprise a control valve that selectably controls the flow of water to thelinear element 32. The user can interact with theremote control 55 to turn on or turn off the supply of fluid (e.g., water) to the fluid hose. In embodiments in which thereel assembly 1 includes an electrical cord or cable as thelinear element 32, thecontrol mechanism 58 can comprise an electrical switch that selectably controls the supply of current to thelinear element 32. The user can interact with theremote control 55 to turn on or turn off the current supplied to thelinear element 32. In addition, in various embodiments, the user can interact with thecontrol mechanism 58 to automatically turn off the supply of fluid and/or current and to initiate re-spooling of thelinear element 32 onto thespool drum 8. - As shown in
FIG. 18 , a wind-inswitch 56 and apower switch 57 can be provided on thereel assembly 1. In some arrangements, thecontroller 25 may continuously monitor the wireless network for any incoming commands transmitted from theremote control 55 to thecontroller 25. Such continuous monitoring may draw power from thebattery 34, reducing the overall lifetime of thebattery 34. Beneficially, in the embodiments disclosed herein, thecontroller 25 and thereel assembly 1 can have an OFF mode in which the user presses thepower switch 57 to OFF and an ON mode in which the user presses thepower switch 57 to ON. When thepower switch 57 is switched to OFF, thereel assembly 1 can shut down such that thebattery 34 provides no power to the other components (e.g., the controller 25) of thereel assembly 1. In the OFF mode, therefore, in some embodiments, thecontroller 25 may not monitor any activity of thereel assembly 1. - When the
power switch 57 is switched to ON, the user can pull thelinear element 32 from thespool drum 8 to unspool thelinear element 32. For example, in some embodiments, the user can manually activate the control mechanism 58 (e.g., a water faucet in embodiments in which thelinear element 32 is a water hose) to supply fluid and/or current to thelinear element 32. In other embodiments, the user can interact with theremote control 55 to activate the control mechanism 58 (e.g., a smart water valve for embodiments that utilize a water hose) to supply fluid or current to thelinear element 32. When the user is finished using thelinear element 32 andreel assembly 1, the user can depress the manual wind-inswitch 56, which can automatically shut off the flow of fluid or electricity to thelinear element 32 and automatically wind in thelinear element 32 to re-spool thelinear element 32 about thespool drum 8. For example, thecontroller 25 can send a shut-off signal to thecontrol mechanism 58, and/or can send a wind signal to themotor 19 to cause themotor 19 to spool thelinear element 32 onto thedrum 8. In other embodiments, the user can interact with theremote control 55 to communicate with the controller 25 (e.g., over a wireless network) to shut off the flow of fluid or electricity to thelinear element 32 and/or to wind in thelinear element 32. In still other arrangements, when the user depresses thepower switch 57 to the OFF position, thecontroller 25 can automatically cause the flow of fluid or electricity to shut off and the linear element to spool onto thedrum 8. - In some embodiments, the
controller 25 can be programmed to place thereel assembly 1 in a sleep mode if a predetermined amount of time passes with little or no activity. For example, the controller can comprise processing electronics (including active and/or passive components) that can determine whether themotor 19 is operating to spool thelinear element 32, and/or whether thelinear element 32 is being unspooled from thedrum 8. For example, in some embodiments, the user can manually unspool thelinear element 32 from thedrum 8 by pulling the linear element. Pulling thelinear element 32 can induce a back electromotive force (EMF) in themotor 19 that can be monitored by thecontroller 25. If themotor 19 has been inactive for a predetermined time period, e.g., thelinear element 32 is not being spooled onto or unspooled from thespool drum 8, then thecontroller 25 can place the reel assembly in the sleep mode. In still other arrangements, the reel assembly can include one or a plurality of sensors that can detect system activity. For example, one or more motion sensors (e.g., accelerometers, gyroscopes, position sensors, etc.), one or more optical sensors, or other types of sensors can be provided on thecontroller 25, on thespool drum 8, on various portions of thelinear element 32, or on any other suitable portion of thereel assembly 1. The sensors can send signals to thecontroller 25, and based on the signals from the sensors, thecontroller 25 can determine whether to place theassembly 1 in sleep mode. - Beneficially, when the system is in sleep mode, the
battery 34 need not supply any electrical power to thecontroller 25 or any other components of thereel assembly 1. For example, in sleep mode, thecontroller 25 may not continuously monitor for wireless signals being transmitted by theremote control 55 or other signals from other components (such as the control mechanism 58). Thus, when in sleep mode, the life of thebattery 34 may beneficially be extended. Thereel assembly 1 can move from the sleep mode to the activated ON mode when the user pulls the linear element 32 (or if the user engages the ON switch in some embodiments). When the user pulls thelinear element 32, thelinear element 32 will tend to unspool from thespool drum 8, causing thespool drum 8 to rotate. Rotation of thespool drum 8 can induce the back EMF in themotor 19. The back EMF can be detected by processing circuitry in thecontroller 25, and thecontroller 25 can activate thereel assembly 1 for operation by the user. After activation from sleep mode, the user can operate theremote control 55 and/or the switches on thereel assembly 1 to use thereel assembly 1. - Thus, the embodiment of
FIG. 18 enables automatic and/or manual control of the reel assembly. The use of the sleep mode can beneficially extend the battery life of thebattery 34. It should be appreciated that other buttons and functionalities can be included in thereel assembly 1 ofFIG. 18 . -
FIGS. 19A-24 illustrate the incorporation of awear ring assembly 60 into thereel assembly 1. Thereel assembly 1 can be any suitable reel assembly, including those explained herein.FIG. 19A is a schematic perspective exploded view of awear ring assembly 60, according to various embodiments.FIG. 19B is a schematic perspective exploded view of awear ring assembly 60, according to another embodiment.FIG. 19C is a schematic perspective view of the wear ring assembly ofFIG. 19A in an assembled configuration. Thewear ring assembly 60 can comprise awear ring 61 havingfirst portion 61 a configured to removably connect to asecond portion 61 b. Thewear ring 61 can be disposed within awear ring support 62. As shown inFIGS. 19A-19B , thewear ring support 62 can comprise afirst support 62 a configured to removably connect to asecond support 62 b. For example, as shown inFIGS. 19A-19B , thewear ring 61 can comprise aridge 63 configured to be received within a correspondinggroove 64 of thewear ring support 62. Thewear ring 61 ofFIG. 19B may be generally similar to thewear ring 61 ofFIG. 19A , except thewear ring 61 ofFIG. 19B may be thinner, e.g., may be entirely disposed within thewear ring support 62. - Beneficially, the
wear ring assembly 60 ofFIGS. 19A-19C can enable improved spooling and/or unspooling of thelinear element 32 about thespool drum 8. For example, thewear ring 61 can comprise a smooth, relatively hard surface to enable thelinear element 32 to slide through anopening 65 in thewear ring assembly 60 with reduced friction. The reduced friction provided by thewear ring 61 can enable the user to easily pull thelinear element 32 from thespool drum 8. In various embodiments, thewear ring 61 can comprise a polymer, such as Delrin® (acetal or polyoxymethylene, manufactured by DuPont™ which can enable relatively low friction engagement between thelinear element 32 and the inner surface of thewear ring 61. Moreover, as explained herein, the relatively constrained opening 65 can reduce kinking of thelinear element 32 by smoothing out any bends or kinks in thelinear element 32 prior to spooling onto thespool drum 8. - In addition, the use of a plurality (e.g., two)
portions wear ring 61 and the use of a plurality (e.g., two) supports 62 a, 62 b can beneficially enable the user to replace thewear ring 61 if thewear ring 61 were to degrade or otherwise experience reduced performance during use. For example, in some embodiments, the first andsecond portions wear ring 61 can be removably engaged snapped, threaded, or otherwise engaged) to one another. In some arrangements, the first andsecond supports portions wear ring 61 and of thesupports narrow opening 65 about thelinear element 32 proximal theoutlet 39, which may be wider than thelinear element 32 and theopening 65. -

As shown inFIGS. 21-24 , thehousing 66 to which thewear ring assembly 60 is coupled can be connected with the spoolingsupport 13, such that thehousing 66 and wearring assembly 60 translate along the spooling support axis S (seeFIG. 2 ) so as to provide a uniform spool onto thespool drum 8. As shown inFIGS. 22-24 , for example, thehousing 66 can couple with the spooling actuator 23 (such as a reversing screw) by way of connectingsegment 67. - As explained above, as the
linear element 32 is spooled onto thespool drum 8, thehousing 66 and wearring assembly 60 may translate along the spooling axis S. e.g., due to rotation of the spooling actuator 23 (e.g., a reversing screw). The translation of thewear ring assembly 60 can enable thelinear element 32 to uniformly spool onto thespool drum 8. Moreover, the diameter or lateral major dimension of theopening 65 of thewear ring 61 may be larger than the outer dimension of thelinear element 32, such that theopening 65 constrains thelinear element 32 and reduces kinking or bending of thelinear element 32. For example, the inner major dimension of theopening 65 can be in a range of 1.1 times to 2 times the outer major dimension of thelinear element 32, in a range of 1.2 times to 1.8 times the outer major dimension of thelinear element 32, or in a range of 1.2 times to 1.4 times the outer major dimension of thelinear element 32. -
