## Title
Direct current powered hose rewinding apparatus

## Abstract

The present invention relates to portable hose carts for handling and storage of flexible hoses, such as garden or air hoses. The cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, an enclosure for supporting the spool, wheels at one end of the base of the enclosure, and a handle assembly for tilting the frame onto the wheels to facilitate moving the device. The handle assembly is telescoping mounted and includes a handle mounted near the top of the handle assembly. The spool is rotatable by either a direct current powered motor or a folding manual crank. Power from the electrical motor is transferred to the spool via an infinitely adjustable torque transfer assembly. When the cover is in the open position, the direct current motor is operationally locked out, and when the cover is rotated into the closed position, the direct current motor is operable. The device may further include a reciprocating guide assembly that operates during rotation of the spool to rewind the hose into a compact configuration.

FIELD OF THE INVENTION
This invention is directed to hose rewinding apparatus for flexible hoses. More specifically, the present invention relates to a direct current powered, motor driven hose rewinding apparatus with manual override that is mounted within a protective safety enclosure. The safety enclosure includes a telescoping handle and a pair of wheels for easy transport and storage.
BACKGROUND INFORMATION
The prior art has proposed a number of different structures for rewinding and storing a hose when it is not in use. These devices generally include stationary hose reel hangers that can be mounted to a surface of a building, such as an outer wall of a house, or portable hose reel carts that permit ready transport of the hose from one location to another.
In the past it was common to retrieve hoses and the like by manually winding them around a suitable structure, such as a wall mounted hanger, or simply bundling them into loose coils. Surface (or wall) mounted hose reels or hangers come in a wide variety of configurations. For example, one surface mounted hose hanger includes a simple, semi-circular metal or plastic support that is mounted to the building, over which the hose is looped or hung. Another surface mounted device or reel includes a rotatable fitting that is mounted to the building surface to which a manually rotated reel is mounted. Unfortunately, when hose is pulled out from such manually wound devices, it often becomes snarled or tangled and requires appreciable time and effort to correct the situation. Additionally, these surface mounted reels and hangers are often considered unsightly, particularly if they are mounted to the front of the building and are not covered or otherwise obscured by plants or foliage.
Portable hose reel carts permit ready transport of the hose from one location to another. Portable hose reel carts typically include an open, manually rotatable reel or spool positioned between a pair of side frames with wheels. The hose is manually wound upon the reel for storage and pulled or dispensed from the reel for use.
Although such carts have become wide spread in use because of their portable storage capabilities, they do have drawbacks. First, these devices require manual winding of the hose. Rewinding long hoses requires a considerable effort. Due to the low positional location of the winding mechanism on these devices, many users may be physically unable to complete the rewinding. Additionally, a hose stored on such a reel is exposed to the elements. Often hoses are made of rubber or like materials that can become stiff or brittle and can break when subjected to ultra-violet radiation or low temperature extremes, particularly with advanced age.
Portable hose reel carts may also be considered by some to be unsightly. Given that most hose reel carts are designed for use in and around garden and lawn areas, it is expected and natural for these carts to become dirty. As such, some users may be inclined to constantly remove a hose reel cart, particularly from the front of a house, when, for example, the cart becomes dirty, muddy or discolored.
In an effort to solve some of these problems, a number of hose retrieval devices have been developed which automatically retrieve and rewind hose on a reel in such a manner so as to avoid tangling the next time the hose is deployed or paid out. Such devices generally include a reel and a level wind mechanism for guiding the hose onto the reel. The level wind mechanism includes a traversing screw, a guide rod, and a follower. The reel is generally directly driven by a motor and/or an intermeshing clutch assembly. Unfortunately, the electric motors of the prior art devices have voltage requirements that reduce portability and increase the risk of electrical shock. Additionally, the clutch mechanisms utilized on these devices are either completely engaged or completely disengaged and lack an infinitely adjustable torque transfer assembly to allow operator controlled speed and/or force of hose retrieval.
Unfortunately, many of these motorized devices also lack a suitably safe enclosure to protect the operator and/or small children from being accidentally caught in the device. For example, none of the motorized hose reels known are equipped with safety interlocks to prevent the motor from being engaged if an enclosure cover is opened. To compound the problem, many of these devices do not provide for an emergency stop and require the entire hose to be retracted before the device can be stopped. Retracting the entire hose may take several seconds and exacerbates emergency situations such as when a person or pet has been caught in the machine or in the hose as it is retracted. In addition, none of the devices known provide a disengaging hose winding guide. The level winds of the prior art are capable of causing severe damage to an operator, child or pet that may accidentally get caught in the rewinding device.
Accordingly, there exists a need for a rechargeable battery operated motorized hose rewinding and storage device that permits safe motorized take-up and manual dispensing of a hose that is also aesthetically pleasing. Such a hose rewinding and storage device that can be safely used to retract and “hide-away” the hoses stored therein when not in use. The hose rewinding device should also be constructed for easy transport and storage while maintaining a overall compact profile.
DESCRIPTION OF THE PRIOR ART
A number of hose rewinding assemblies in the prior art utilize electric motors to drive a reel for retracting an elongate member such as a cord or hose. Examples are disclosed as follows:
U.S. Pat. No. 4,832,074 discloses an automatic hose rewinding device having an alternating current (AC) motor driven reel. The desired amount of hose is pulled out of the enclosure manually for use. After use a button is pushed once and the hose is completely retracted until a device on the end of the hose strikes a bar to disengage the AC motor. The design of the device does not allow small increments of the hose to be retracted. If the operator wishes to use a smaller amount of hose, the entire hose must be retracted and the desired amount of hose must be manually pulled out again. Additionally, the use of alternating current reduces portability of the device and increases the risk of electrical shock.
U.S. Pat. No. 4,513,772 discloses an automatic hose winding apparatus having an intermeshing, non-slipping clutch. The desired amount of hose is pulled out of the enclosure manually for use. For retraction, the operator must manually lock the intermeshing clutch mechanism in place. When the hose is completely retracted a device on the end of the hose strikes a lever to disengage the intermeshing clutch. The design of the device allows increments of the hose to be retracted, however, the operator must manually disengage the clutch before any amount of hose can be manually payed out. The apparatus makes no disclosure or suggestion of a protective enclosure or a disengaging hose guide.
U.S. Pat. No. 5,495,995 discloses a motor driven hose reel assembly. The device interconnects two sensors and a motor to monitor the quantity of hose manually pulled from the reel. By pulling on the hose manually, the hose is rewound in an amount less than that necessary to completely rewind the hose. Because the device is operated in a retraction direction when the hose is pulled, the design requires the operator to overcome the pulling force of the device to extend hose from the machine.
U.S. Pat. No. 4,012,002 discloses a coupling mechanism for use in conjunction with a hose reel to automatically and selectively engage or disengage the reel and motorized drive train. The coupling utilizes a sliding spring pin on the drive train which is designed to automatically engage one of a series of cooperating stop lugs on the reel to transmit the driving power of the motor to the rotatable reel. The spring pin can be manually locked in a disengaged position to allow the hose reel to freewheel. When the spring pin is engaged the device operates in direct drive from the motor.
U.S. Pat. No. 6,149,096 discloses a retractable reel device especially useful for electrical cables. The device is specifically designed to allow an operator to pull out a desired amount of cable. Once the cable is paid out, the device maintains a predetermined amount of tension on the cable. Thereafter, any slack in the cable is automatically retracted by an AC motor.
Thus, what is lacking in the art is a direct current powered hose rewinding device having an infinitely adjustable torque transfer method for modulating hose retrieval. The references are further deficient in teaching the use of a rechargeable battery in combination with a direct current (DC) motor for powering the hose retrieval device. Moreover, the references are deficient in teaching an enclosure with safety interlocks that prevent the motor from being engaged when a cover is in an open position. The devices are further deficient in teaching a safety hose guide assembly that is capable of disengagement in the event that the path of the device is inadvertently blocked. The prior art devices are still yet deficient in teaching a motorized hose rewinding device with manual override, allowing the hose to be retracted manually as well as by motor. Even further, the prior art devices are deficient in teaching a device which includes a telescoping handle and a pair of rearwardly mounted wheels for easy transport of the device.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides an improved direct current powered hose rewinding device having an enclosure including a telescoping handle and a pair of rotatably mounted wheels to provide portability. Additional features include various embodiments of infinitely variable torque transfer assemblies which cooperate with the direct current motor for power-assisted hose retrieval.
The apparatus includes a motorized rotatable spool carried and contained within an enclosure. The rotatable spool includes a hub and a pair of flanges at opposing ends of the hub, and is configured for storage, motorized take-up, and manual pay-out of the flexible hose. Power for the motorized spool is supplied through a control assembly that includes a rechargeable battery, a main power switch, and at least one safety interlock. The safety interlock(s) are incorporated into the enclosure and prevent motorized operation of the spool when the enclosure is opened.
The enclosure has left and right side wall panels, front and rear wall panels extending between the left and right wall panels, and a cover. The enclosure is configured for receiving a rotatable spool for storing a length of flexible hose within the enclosure.
The cover pivots about a pair of hinges that mount the cover to the enclosure for movement between a closed position and an open position. The hinge arrangement includes hinge pin bosses extending upwardly from a top edge of the rear panel, wherein a hinge pin extends from each of the hinge pin bosses about laterally and in axial alignment with respect to each other. The cover is formed having a depending lip and a pair of pockets that are integrally formed into the rear wall of the depending lip for cooperation with each respective hinge boss and pin. Preferably, the pins are formed as fluted cylindrical elements extending from the bosses, axially aligned to one another to facilitate rotational movement.
When the cover is rotated into the open position, a safety interlock switch assembly prevents motorized operation of the hose spool. When the cover is rotated into the closed position, an engagement pin extending from the underside of the cover cooperates with the safety interlock switch to allow motorized operation of the spool.
To facilitate take-up and pay-out of the hose with the cover closed, the front wall panel includes a cut-out portion extending downward from the top edge thereof adjacent to the junction with the cover. In this arrangement, when the cover is closed, the cut-out accommodates traversing a portion of the flexible hose therethrough.
In one embodiment a reciprocating hose guide assembly is linked to the spool. When the spool is rotated, the reciprocating hose guide will move back and forth across the spool to uniformly and smoothly wrap the hose on the spool to provide a compact storage configuration.
In a further embodiment, the reciprocating hose guide can be released from its double-helix lead-screw in the event that its path becomes blocked, such as by debris or when a hand or arm is mistakenly placed in the opening. Alternatively, the hose guide may be manually disengaged to facilitate easy hose pay-out, and can thereafter be repositioned before being manually re-engaged.
A sliding seal fluid inlet joint permits the hose outlet joint to rotate with the hose spool without disconnecting the hose. This arrangement permits rotating the spool without twisting or torquing internal components, while maintaining sealed fluid communication between the water supply and the hose.
For rotational operation the spool is provided with a winding means capable of manual rotational movement of the spool in relation to the enclosure and an electrically energized power assist means for selective and operative engagement of the winding means. The winding means is illustrated as a hand crank extending through the enclosure and connected to the spool at about its axis of rotation. The power assist means is illustrated as a DC powered motor mounted within the enclosure and connected to the hose spool via a torque transfer assembly. In some embodiments the torque transfer assembly utilizes a dynamic clutch assembly to transfer torque from the motor to rotate the torque transfer assembly thereby rotating the spool. In other embodiments the clutch assembly may regulate torque supplied to the spool via a foot pedal operated clutch assembly. In one embodiment the foot operated cantilever forces an idler friction wheel into engagement with a drive friction wheel and a spool friction wheel to selectively couple and decouple the DC motor to and from the spool to modulate the pulling force and rotational speed of the hose spool. When the foot pedal is depressed the main power switch of the control assembly supplies current from the battery to start the DC motor and the idler friction wheel is forced into engagement to provide the desired speed and/or force required for hose retrieval. Release of the pedal stops the motor and allows hose to be freely pulled from the spool as desired.
In an alternative embodiment the foot operated cantilever forces an idler gear into engagement with a drive gear and a spool gear to selectively couple and decouple the DC motor to and from the spool to modulate the pulling force and rotational speed of the hose spool. When the foot pedal is depressed the main power switch of the control assembly supplies current from the battery to start the DC motor and the idler gear is forced into engagement to provide the desired speed and/or force required for hose retrieval. Release of the pedal stops the motor and allows hose to be freely pulled from the spool as desired. The device may also include at least one idler gear to adjust torque and rotational speed of the hose spool with respect to the motor.
Because motors often operate at relatively high RPM, the DC motor may include an internal gear train coupled between the armature of the DC motor and the DC motor output shaft. The internal gear train is capable of reducing RPM output and increasing motor torque.
Power for the control assembly is provided by a removable, replaceable, and rechargeable battery assembly conveniently stored within its own closed compartment in the enclosure. Connection to the battery is made via a unique clip-on connector that also provides an integrated battery charging jack. The clip-on connector is constructed and arranged to prevent the clip from being incorrectly connected to the battery and the assembly requires directional installation into the enclosure for electrical connection to the control assembly. The integrated charging jack in the clip-on connector allows convenient battery recharging without disconnecting the clip from the battery. In this manner the battery can be safely and easily removed, recharged, and/or reinstalled into the enclosure without danger of incorrect connection.
Therefore, it is an objective of the present invention to provide a motorized hose rewinding apparatus wherein the speed and/or force of hose retrieval is modulated by virtue of an infinitely adjustable torque transfer assembly.
It is a further objective of the present invention to provide a motorized hose rewinding apparatus that is constructed to utilize a DC power source.
It is still a further objective of the present invention to provide a motorized hose rewinding apparatus having a removable and rechargeable power source.
Yet another objective of the present invention is to provide a battery operated rechargeable motorized hose rewinding apparatus capable of protecting the hose during storage from direct contact with the elements.
Still another objective of the present invention is to provide a motorized hose rewinding apparatus that is aesthetically appealing to consumers.
Still yet another objective of the present invention is to provide a motorized hose rewinding apparatus that includes an enclosure having safety interlocks to prevent motorized operation when the enclosure is opened.
Still yet another objective of the present invention is to provide a hose rewinding device that provides portability by utilizing wheels and telescoping handle assembly to permit easy transport of the device.
Still yet another objective of the present invention is to provide a hose winding guide assembly that includes automatic as well as manual disengagement features.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
It is to be understood that while a certain form of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
Referring now to FIGS. 1 and 2, generally, there is shown a direct current powered hose rewinding device 100 in accordance with the principles of the present invention. The hose rewinding device 100 includes a motor driven spool 12 onto which the hose is mechanically wound or taken up, and from which the hose is manually fed out or paid out.
The enclosure 14 includes a front wall panel 30 and a rear wall panel 34, a left side wall panel 32, a right side wall panel 36, and a pivoting cover 38. Optionally, the enclosure 14 can include a bottom panel (not shown) for substantially fully enclosing the spool 12 and protecting the spool 12 and hose from the elements. The optional bottom panel is preferably constructed as a reversible member with an enhanced friction engaging first surface and a relatively smooth second surface. In this manner the bottom panel could be inserted to prevent the apparatus from skidding on hard surfaces where staking is not practical. In addition, the bottom surfaces of the left side wall panel 32 and right side wall panel 36 may be constructed with optional rubber pads 33 to further engage hard surfaces. As will be apparent from the drawings, the front, rear and side panels 30-36, and the cover 38 enclose the spool 12 such that the spool is substantially not visible from outside of the enclosure 14 when the cover 38 is closed.
In a first embodiment the front panel 30 of enclosure 14 includes a cut-out portion 52 extending downwardly from the top lip thereof. The cut-out portion 52 can be elongated and is suitably sized to accommodate a standard size garden hose so that the hose can be paid-out from or taken-up onto the spool 12 without lifting the cover 38. That is, the hose can freely move through the cut-out opening 52 without opening the cover 38.
In a most preferred embodiment the front panel 30 of enclosure 14 includes an elongated cut-out portion 52 extending downwardly from a top lip thereof. The cut-out portion 52 is sized to accommodate a reciprocating hose guide assembly 50 (FIG. 3A) so that the hose can be uniformly and smoothly wrapped on the spool 12 to provide a compact storage configuration or easily paid-out from the spool 12 without lifting the cover 38.
The enclosure 14 preferably includes a pair of wheel recesses 40 extending inwardly into the right side panel 36 and left side panel 32 for housing the rotatably mounted wheel assemblies 43. The wheel recesses 40 are generally positioned at a lower rear portion of the side panels and each includes a centrally located wheel assembly hub 212 and aperture 41 (FIG. 4) for accepting the wheel 200 and axle portion of a wheel assembly 43.
In a most preferred embodiment, the right side panel wheel recess 40 includes a foot pedal aperture 45. The foot pedal aperture is adapted to allow the second end 42 of the cantilever 110 (FIG. 6A) to extend therethrough. The foot pedal 47 extends outwardly with respect to the side panel 36, as shown in FIGS. 3A and 3B, when the foot pedal 47 is in an operational position and is recessed with respect to the outermost portion of the side panel 36, as shown in FIG. 1, when the foot pedal 47 is in a storage position. This construction prevents inadvertent operation of the foot pedal 47 and permits compact storage of the device.
A manual override winding crank 24 is external of the enclosure 14 and extends through a side wall for connection to the spool 12, preferably on an end opposite to that of the in-tube 20 (FIG. 2), to facilitate manual take-up of the hose. The crank 24 includes a folding handle 25 capable of folding into a recess 26 formed in the crank 24. The handle releasable lock 28 (FIG. 3A) in the crank 24 cooperates with detents in the handle 25 to permit the handle 25 to be locked into either a position parallel to the crank or a position perpendicular to the crank. Locking the handle 25 in the parallel position permits the spool to rotate without the danger of the rotating handle hitting or snagging objects or persons within its path and also permits a compact enclosure.
Now referring to FIGS. 3A and 3B, the motorized hose rewinding apparatus 100 is illustrated partially exploded. The battery cover 48 and handle 25 are illustrated in their respective open positions and the foot pedal 47 in its respective operative position.
Incorporated into the enclosure 14 is a lockout assembly 62 that prevents the direct current motor 98 (FIG. 6A) from operating when the cover 38 is in the open position. The lockout assembly 62 is illustrated as, but not limited to, an engagement pin 64 cooperating with a normally open micro-switch 68. Other devices well known in the art suitable for sensing an open cover and locking out electrical devices when the cover is open may be substituted for the pin and switch assembly illustrated herein. Such devices may include but should not be limited to micro-switches, proximity switches, mercury switches, mechanical switches, optical switches and the like.
Also visible is the reciprocating hose guide assembly 50 and the basket member 44. The reciprocating hose guide assembly 50 contains a double helix lead-screw 54, guide rod 56, and carriage 58. The reciprocating hose guide assembly 50 is linked via gear-train 96 (FIG. 6A) to the hose spool 12 so that when the hose spool 12 is rotated, the double helix lead-screw 54 rotates at a desired ratio with respect to the hose spool 12. The lead-screw 54 is journaled for rotation between side members 32 and 36 and is substantially parallel to the central hub portion of spool 12. The lead-screw 54 engages the carriage 58 via follower 66, allowing the carriage 58 to move back and forth across the lead-screw 54 and the guide rod 56 when engaged during both manual and motorized operation. The follower 66 can be manually disengaged from the lead-screw 54 to permit easy pay-out of hose or repositioning of the carriage 58. Operation of the hose guide assembly 50 permits hose to be uniformly and smoothly wrapped on the spool 12 to provide a compact storage configuration. Optionally the follower 66 may include a disengagement feature that permits the carriage 58 to release from the lead-screw 54 in the event that the carriage 58 is obstructed during motorized or manual hose rewinding.
Referring to FIG. 4, the spool 12 is supported by and rotatably mounted within the enclosure 14. The spool 12 includes a central hub 16 constructed of two mating halves 16A and 16B and a pair of radially extending flanges 18 that are configured to accommodate a length of the flexible hose wrapped around the hub 16 between the flanges 18. In a typical arrangement, the hose spool 12 can store upward of 150 feet of 5⁄8 inch garden hose.
Those skilled in the art will recognize that the hose spool 12 includes a water inlet port or in-tube 20 and an outlet port or out-tube 22. The in-tube 20 is mounted to the enclosure 14 at about the axis of rotation of the spool 12. The in-tube 20 is connected to the out-tube 22 by a sliding seal arrangement 23 which will be recognized by those skilled in the art. This arrangement permits the in-tube 20 to remain fixed to the enclosure 14, while the out-tube 22 rotates with the spool 12. In this configuration, the in-tube 20 and out-tube 22 remain in fluid communication with one another. This arrangement permits rotating the spool 12 without twisting or torquing internal components, while maintaining sealed fluid communication between the water supply and the hose.
Also visible is one embodiment of the torque transfer assembly 68 having the structural transfer cover 46 removed. The transfer cover 46 cooperates with the right side panel 36 to provide structural support to the torque transfer assembly.
Still referring to FIG. 4, the wheel assemblies 43 are shown. Each of the wheel assemblies include a wheel 200 and an axle member 202. The axle member 202 includes an axle stub 204. On a first end of the axle stub is a plurality of integrally formed spring clips 206. The spring clips are constructed and arranged to cooperate with the wheel assembly aperture 41 for push in interlocking installation of the wheel assemblies 43. On a second opposite end of the axle stub 204 is an integrally formed thrust plate 208. In operation, the wheel aperture 210 is placed over hub 212 and the axle member 202 is slid into wheel assembly aperture 41. In this manner the axle stub extends through a central portion of said wheel for interlocking engagement with the rear panel and the thrust plate abuts the wheel to rotatably secure the wheel to the enclosure.
Referring to FIG. 5, an exploded view of the enclosure is shown 14. The panels 30-38 are preferably molded components formed from high strength polymeric (plastic) material, such as polystyrene or the like. The panels 30-38 are most preferably configured such that the front and rear panels 30, 34 have contoured posts 70 that insert into recesses or channels 72 formed integrally and extending vertically along the front and rear edges of each side wall panel 32 and 36. The contoured projections 70 include ramped surfaces or snap-type elements 76 that engage openings 78 in the channels 72 to lock the panels to one another.
Advantageously, this configuration permits ready assembly of the enclosure 14 with a minimum number of tools, and involves a minimum number of parts.
The rear panel 34 includes a telescoping handle assembly 130. The telescoping handle assembly 130 is moveable between a storage position, as illustrated in FIG. 1, wherein the handle is substantially the same height as the enclosure 14 and an in-use position, as illustrated in FIG. 2, wherein the handle extends above the overall height of the enclosure. The telescoping handle 130 assembly preferably includes a pair of spaced apart telescoping members 132 and a handle member 134 extending substantially horizontally between the telescoping members. The rear panel member 34 includes a pair of integrally formed channels 136 constructed and arranged to guide the telescoping handle assembly 130 during movement between the storage and the in-use positions. The telescoping members 132 each include at least one detent 138 constructed and arranged to cooperate with at least one protrusion 140 integrally formed into the telescoping member channels 136 to secure the handle assembly 130 in at least one predetermined position.
The cover or top panel 38 is fitted to the panels 30-36 using a hinge arrangement indicated generally at 80. The hinge arrangement 80 permits pivoting or rotating the cover 38 between the closed position and an open position. The cover 38 is configured so that when opened and maintained in the open position, use of the motorized spool is locked out via lockout assembly 62 (FIG. 3A).
The hinge arrangement 80 includes a pair of integrally formed hinge pin bosses 142 extending upwardly from the top edge 144 of the rear panel 34, each boss including a laterally extending and axially aligned hinge pin 146. In a present embodiment, the cover 38 has a depending lip 88 extending around the perimeter of the cover. The depending lip includes a front 148, a rear 150, a left 152 and a right surface 154, the rear surface having a pair of pockets 156 (FIG. 2) constructed and arranged to cooperate with a respective hinge pin 146 and boss 142. Each of the pockets 156 are configured to permit rotational movement of the cover 38 about the pins 146 for upward rotational movement of the cover.
The rear panel 34 also includes a pair of wheel assembly receivers 158 each constructed and arranged to cooperate with the axle portion of a wheel assembly 43 (FIG. 1). In the preferred embodiment one of the wheel assembly receivers 158 is integrally formed into the left edge 160 of the rear panel and one of the wheel assembly receivers 158 is integrally formed into the right edge 162 of the rear panel. The wheel assembly receivers 158 are positioned to align with the left and right side panel wheel assembly hubs 212 and apertures 41.
The rear panel 34 further includes a pair of integrally formed hooks 164 constructed and arranged to cooperate with a basket member 44 (FIG. 3A), wherein the basket member 44 is constructed and arranged to fit within the enclosure 14 while permitting hose storage about spool 12. The basket member provides storage space within the enclosure for a variety of hose accessories.
Referring to FIGS. 6A, 6B and 6C, one embodiment of the torque transfer assembly 172 and hose guide gear-train 96 are shown. For motorized operation, the motorized hose rewinding apparatus 100 is provided with a DC powered motor 98 connected to the torque transfer assembly 172 which is connected to the spool 12. In these embodiments the torque transfer assembly is illustrated as but not limited to a friction drive assembly 168 (FIG. 6B) and a gear drive assembly 170 (FIG. 6C). In the friction drive assembly 168 a friction drive wheel 106 is rotatably secured within the enclosure and suitably coupled to the direct current motor output shaft 166. At least one friction idler wheel 114 is constructed and arranged for selective engagement with the friction drive wheel 106 and rotatable responsive to rotation of the friction drive wheel 106. At least one driven friction idler wheel 116 is positioned for engagement the friction idler wheel 114 wherein the friction idler wheel 116 is rotatable responsive to rotation of the idler wheel 114. A respective spool friction wheel 118 is secured to the hub 16 of spool 12 to be rotatable therewith, the spool friction wheel 118 being larger in diameter than the friction drive wheel 106. The spool friction wheel 118 is rotatable responsive to the friction idler wheels 114 and 116, thereby enabling the direct current motor 98 to rotate the spool 12 at a rotational speed less than the rotational speed of the friction drive wheel 106.
In the drive gear assembly 170 a drive gear 107 is rotatably secured within the enclosure and suitably coupled to the direct current motor output shaft 166. At least one idler gear 115 is constructed and arranged for selective engagement with the respective drive gear 107 and at least one driven idler gear 117 wherein the idler gears 115 and 117 are rotatable responsive to rotation of the drive gear 107. A spool gear 118 is secured to the hub 16 of spool 12 to be rotatable therewith. The spool gear 118 larger in diameter than the drive gear 107. The spool gear rotatable responsive to the idler gears 115 and 117, thereby enabling the direct current motor 98 to rotate the spool 12 at a rotational speed less than the rotational speed of the drive gear 107.
The preferred embodiment includes a second assembly pivotably mounted within the enclosure illustrated as a cantilever 110 having a first end 164, preferably including the idler wheel 114 or idler gear 115, and a second end 42 including a pivotally mounted foot pedal 47. The construction and arrangement of the second assembly allows the pulling force and rotational speed of the motorized spool 12 to be regulated. For example, when the foot pedal 47 is depressed the current from the battery 132 (FIG. 12) flows through a fuse and is allowed to start the DC motor 98. The idler gear 115/friction wheel 114 is forced into engagement with the drive gear 107/friction wheel 106 and any driven idler gears 117/friction wheels 116 respectively to rotate the spoo1 gear/friction wheel 118 to provide the desired rotational speed and/or force for hose retrieval. It should be appreciated that the clutch assembly may regulate torque supplied to the spool via the foot operated cantilever to modulate pulling force and rotational speed of the hose spool. Release of the pedal 47 stops the motor 98 and releases engagement of the idler gear 115/friction wheel 114, and allows the spool 12 to be freely rotated. In this manner, the operator of the present invention can easily regulate the rewinding of hose around the spool 12 as well as allow hose to be manually paid out.
When the pedal 47 is depressed the motor rotates the spool through the action of the torque transfer assembly 68. That is, the motor 98 rotates the drive gear 107/friction wheel 106, the idler gear 115/friction wheel 114 respectively operatively engages and rotates driven idler gears 117/friction wheels 116, that rotates the spool gear/friction wheel 118 to complete the power-assisted rotation of the spool 12. The hose winding guide lead-screw 54 is caused to rotate through the action of gears 118, 120, and 122. That is, when spool 12 is rotated by motor 98 or by handle 25, the spool 12 and spool gear 118 rotates, which causes the idler gear 120 to rotate, which causes lead screw 54 to also rotate.
Referring to FIGS. 7A and 7B an alternative embodiment of the power assist means is illustrated. In this embodiment a clutch assembly 170 is suitably coupled to the direct current motor output shaft 166 for transferring rotational torque from the direct current motor 98 to the torque transfer assembly 172.
