This invention generally relates to the field of spools, and more particularly to driven spools for manually winding a coil of material such as winding and storing air hose.
Hose reels are known and are in general of the type depicted in U.S. Pat. No. 8,403,250 or European patent number EP 1491480.
The invention provides a simple manual means of winding and storing a coil of material. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In one aspect, the invention provides a spool for winding a coil of material. An embodiment of this aspect includes a first flange and a second flange. A hub extends between the first flange and the second flange to define the channels around the hub upon which the coil may reside. A support structure is found along an inside of the hub and a first handle and a second handle are rotatably mounted to the support structure and each are independently rotatable relative to the other.
The support structure may include a first gusset and a second gusset in spaced relation wherein the first gusset includes a first annular aperture and the second gusset includes a second annular aperture. Each aperture defines a bearing support surface.
The first handle can include a ring rotatably mounted within the annular aperture of the first gusset. The ring can further include a grip spanning an inner diameter of the ring and may be fixedly attached thereto. The outer surface of the ring comprises a bearing surface in relation to the annular aperture of the first gusset.
The second handle can include a ring rotatably mounted within the annular aperture of the second gusset. The ring can further include a grip spanning an inner diameter of the ring and may be fixedly attached thereto. The outer surface of the ring comprises a bearing surface in relation to the annular aperture of the second gusset.
The first and second handles when rotated impart driving rotation to the hub to wind the spool. The handles follow the same path about an axis of rotation of the spool.
The hub and flanges may be oval.
The first handle has a first axis of rotation. The second handle has a second axis of rotation. The spool has an axis of rotation. The first and second handle axes of rotation are parallel to the spool axis rotation.
In certain embodiments the first fixed handle spans the first flange and a second fixed handle spans the second flange. The first and second fixed handles bisect the spools axis of rotation and the first and second fixed handles are between the handles. The flanged sides can include at least one notch for receiving an end of the coil material. The flange side can have two diametrically opposed hose notches.
The support structure can include first and second apertures which define first and second circular bearing surfaces. The first and second handles are mounted for rotation of the first and second circular bearing surfaces respectively.
In certain embodiments a transport handle extends across and inside of the hub and between the first and second handles. The transport handle may be fixed and unitarily formed with the flanges.
Each of the first and second handles can include a ring, body and a grip traversing the ring body wherein each ring body engages one of the bearing surfaces.
The grips can split the ring body with first and second semi-circular aperture segments defined on opposite sides of the grip and being sized to receive a hand therethrough for grasping the grip.
The first handle and the second handle may include a handle axis of rotation. The handles when in rotation simultaneously rotate about a spool axis of rotation.
In another aspect, the invention provides a spool for winding a coil of material. An embodiment of this aspect includes a first flange and a second flange. A hub extends between the first flange and the second flange to define a channel around the hub upon which the coil may reside. A support structure is located along an inside of the hub. A first handle and a second handle are carried by the support structure on opposite sides of a spool axis. The handles when simultaneously rotated in a first direction rotate the spool about the spool axis in a first spool rotation direction. The handles when simultaneously rotated in a second direction rotate the spool about the spool axis of rotation in a second spool rotation direction. The first direction and the second direction are opposite one another and the first spool rotation direction and the second spool rotation direction are opposite.
The first and second handles are rotatably mounted to the support structure and each are independently rotatable relative to the other. The hub is symmetric about the spool axis.
The support structure may comprise a first gusset and a second gusset in spaced relation. Each gusset can include an annular aperture and each annular aperture defines a bearing support surface.
The first handle may include a ring rotatably mounted within the annular aperture of the first gusset. The ring may further comprise a grip spanning an inner diameter of the ring and fixedly attached thereto. An outer surface of the ring comprises a bearing surface in relation to the annular aperture of the first gusset. The second handle may comprise a ring rotatably mounted within the annular aperture of the second gusset. The ring may further comprise a grip spanning an inner diameter of the ring and fixedly attached thereto. An outer surface of the ring comprises a bearing surface in relation to the annular aperture of the second gusset.
In yet another aspect, the invention provides a spool for winding a coil of material that may include a first flange and a second flange. A hub can extend between the first flange and the second flange to define a channel around the hub upon which the coil may reside. There may be a support structure along an inside of the hub that comprises a first gusset and a second gusset. A first handle may be located within an annular aperture of the first gusset. A second handle may be within an aperture of the second gusset. Each handle is rotatable. Each annular aperture includes a center axis that is offset a center spool axis of the spool.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Turning now to the drawings,
A spool 10 for winding a coil of material 60 is shown. The hub 16 extends between a first flange 12 and a second flange 14. The support structure 20 is found along the inside of the hub 16 and a first handle 22 and a second handle 24 are rotatably mounted to the support structure 20 and are each independently rotatable relative to the other 48, 50.
With reference to
For transport of the spool 10 a first fixed handle 52 is illustrated spanning the first flange 12. Likewise a second fixed handle 54 spans the second flange 14. Because the fixed handles 52 and 54 are merely used for convenient transport of the spool 10 it is not the intent to limit then handles construction or mounting to the spool 10 as shown here. Rather, it can be readily appreciated that the fixed handles 52, 54 may be made of plastics, wood, or even metal to name just a few materials. The spool 10 though shown with fixed handles 52, 54 may also be produced without fixed handles or may just include just one fixed handle. The handles maybe formed in molds integral with the flanges or might be later fixedly attached to the spool 10 through any number of means such as fasteners for example. Further, the fixed handles, though illustrated here with an integral and centered rectangular grip portion might include grips with rubber or wood or various ergonomic and aesthetically pleasing materials for example.
Turning now
Further illustrated in FIG. 3's assembly view are the handles 22, 24 formed in two sections 42a, 42b which hold together the two sections of the spool previously discussed which include the flanges 12, 14, hub 14, and support structure 20. The handle sections 42a, 42b are fixedly attached to one another by a fastener means 62. Screws 62 are illustrated as the fastening means but certainly other fastening means for example rivets may be used or the two handle section might be made so as to just snap together for example. In certain embodiments the two sections of the spool come together and are secured to one another via the handles 22, 24 but the two spool sections could be formed together and not as separated section or they might be as shown here in two sections and joined using any known means such as fasteners, glue, plastic weld or even snapped together to give just a few examples.
The handles 22, 24 include hand grips 44 which are used to manually impart rotational force to the handles 22, 24 which in turn rotate the entire spool 10. In one embodiment grips 22, 24 may span the inner diameter of the rings 42 but can be fixed on the ring in various configurations so as to permit the necessary rotation of the handles about their axes of rotation 28, 30.
Hose notches 56 may be located on the flanges 12, 14 as desired. Shown here is one envisioned embodiment with diametrically opposed hose notches 56 on the flanges 12, 14. Although four hose notches 56 are shown it can be readily seen that the spool 10 might be made without any hose notches 56 or may be made with number of hose notches 56 from one to four or more depending on the desired aesthetic presentation or depending functionally on the coil of material 60 to be wound upon the hub 16.
The flanges 12, 14 the hub 16 and the support structure 20 may be oval as illustrated, but might just as well be circular or of any shape provided the handles 22, 24 are rotatable relative to the hub 16 so as to permit driving rotation to be applied thereto so as to rotate the spool 10 to wind a coil of material 60. Likewise, the annular apertures 36, 38 may be annular or circular or of a shape provided they can receive the handles 22, 24 so as to permit rotational force to be applied thereto for winding the coil of material 60 in the channel 18 about the hub 16.
Likewise rotational force may be applied to each handle 22, 24 so as to rotate the handles 22, 24 in a counter-clockwise manner. Thus, the first handle 22 turns counter-clockwise about its first handle axis of rotation 28 while the second handle 24 turns counter-clockwise about its second handle axis of rotation 30. Thus, the handles follow the same counter-clockwise path of rotation about the spool axis of rotation 26. In turn, the spool 10 rotates counter-clockwise to wind a coil of material 60 about the hub 16.
The spool 10 may be may be made various materials and of such dimension and weight so as to permit an operator to lift the spool 10 with both hands, apply rotation force thereto, and coil a winding of material upon the hub for storage and transport for example.
