The present invention relates generally to winches and jacks and, more particularly, to handles for winches and jacks that are adjustable.
Towed vehicles or trailers are often designed to secure and haul cargo. Trailers may be arranged to haul specific types of cargo such as boats, automobiles, consumer products, and the like. Many such cargo items are heavy and difficult to move or maneuver onto the bed or frame of a towing trailer. To assist in moving or maneuvering cargo onto a towing trailer, such trailers are often equipped with a trailer winch assembly, whereby the winch assembly may commonly be attached to the tongue of the trailer. The winch may be connected to a cargo item by, for example, a strap, cable, rope, or chain for pulling the cargo item onto the trailer. There may also be brake or work winches that may be used for lifting or pulling.
The winch assembly may typically use a winch handle to rotate a drum thereby winding the strap or cable around the drum and thus pulling the cargo item towards the winch and onto the trailer. The winch assembly may also be used to unload a heavy item by rotating the drum in the opposite direction to unwind a strap or chain to allow the cargo item to be safely and easily slid off of the trailer.
Trailers are commonly supported by trailer jacks. Such jacks may typically be securable to the trailer tongue to support the trailer in a horizontal position when the trailer is uncoupled from a towing vehicle. Trailer jacks may also include jack handles. These jack handles may be of a similar form and function to winch handles that may be arranged to be manually rotated to raise and lower the tongue portion of a trailer.
Winch handles and jack handles may typically be manufactured or fabricated for specific winches or jacks or for specific applications and may not allow for any modification in the configuration or operation of the handle.
An adjustable handle assembly for adjusting a winch or jack is described. The handle assembly may include a crank bar a slide bracket and a grip. The crank bar may include an attachment aperture and adjustment aperture, wherein the attachment aperture may be attachable to a shaft of a winch or jack. The slide bracket may include at least one slot, such as a pair of slots, and a grip aperture, wherein the slide bracket may be capable of engagement the said crank bar forming an overall length of the handle assembly. The grip may be attachable to the grip aperture. There may be at least one fastener capable of engagement with the adjustment aperture and either of the first slot or the second slot. The crank bar may be adjustable along a length of the either the first slot or the second slot. The handle assembly may be lengthened to increase a force applied to the winch or jack. The handle assembly may be shortened to accommodate rotation of the handle assembly within a tight space.
Objects and advantages together with the operation of the embodiments disclosed herein may be better understood by reference to the detailed description taken in connection with the following illustrations, wherein:
Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. It is to be understood that other embodiments may be utilized and structural and functional changes may be made without departing from the respective scope of the invention. As such, the following description is presented by way of illustration only and should not limit in any way the various alternatives and modifications that may be made to the illustrated embodiments and still be within the spirit and scope of the invention.
An adjustable handle assembly 10 for use with a winch, such as a trailer or brake winch, or jack is illustrated in
The slide bracket 14 may be of any appropriate shape or size, such as a generally rectangular or square shape (
The slide bracket 14 may include a grip aperture 26 (
The slide bracket 14 may also include at least one flange 44 (
The crank bar 16 may be of any appropriate shape or size, such as of a generally rectangular planar, dog-leg or S-shape (
The first linear portion 32 may include an attachment aperture 38 (
The handle assembly 10 may be secured to the trailer winch or jack such that rotation of the handle assembly 10 may make the winch operable to pull or otherwise move objects, such as cargo, or to make the jack operable to adjust the height of a trailer. The handle assembly 10 may also be secured to a brake or work winch to aid in pulling or lifting. While described herein as being used with a trailer winch, brake winch, or jack, it is to be understood that the handle assembly 10 may be used with any appropriate type of device or apparatus that may have use for a handle and should not be limited to those described herein.
The transition portion 36 may be of any appropriate shape or size and be located at any appropriate position on the crank bar 16. For example, the transition portion 36 may be disposed between and connect the first linear portion 32 and second linear portion 34 (
The second linear portion 34 may be of any appropriate shape or size and may be located at any appropriate position on the crank bar 16. For example, the second linear portion 34 may be generally longer than the first linear portion 32 and may be located towards a second end of the crank bar 16. As another alternative, the first linear portion 32 may be generally longer than the second linear portion 34 and may be located towards a second end of the crank bar 16. The second linear portion 34 may also include an adjustment aperture 40 (
The aperture 40 in the second linear portion 34 may generally be utilized to secure the crank bar 16 to the adjustable slide bracket 14. For example, the crank bar 16 may be secured to the adjustable slide bracket 14 by a fastener 18 (
For example, the fastener 18 may be a threaded bolt, and the attachment of the crank bar 16 to the adjustable slide bracket 14 may be completed by threading another fastener, such as a nut 42 or other such mechanism, onto the bolt 18. It is to be understood that in such an arrangement the threaded fastener 18 may be passed through the aperture 40 and either one of the slots 22, 24, whereby the nut 42 may then be threaded onto the bolt 18 (
In another example, the fastener 18 may be a carriage bolt and the nut 42 may be a flange nut. A carriage bolt 18 may include square portion proximate to its head that may fit snuggly into the aperture 40 of the second linear portion 34, whereby the aperture 40 may be of a generally square shape (
The handle grip 12 may be of any appropriate shape or size, such as a generally cylindrically shape (
The handle grip 12 may be attached to the slide bracket 14 by any appropriate means. For example, the handle grip 12 may be rotatably attached or otherwise secured to the slide bracket 14 by passing a fastener 20 through a central bore (not shown) in the grip 12 and also through the aperture 26 in the bracket 14. The fastener 20 may be secured with another fastener, such as a nut 30 (
The fastener 20 may be of any appropriate shape, size or type, such as a screw, bolt or the like. For example, the fastener 20 may include a threaded shaft 46 and a head 28. The head 28 may be slightly larger than the shaft 46 and may abut the grip 12 at one end of the central bore to prevent the fastener 20 from passing all the way though the central bore and to position the fastener 20 relative to the grip 12 (
In such an arrangement, the portion of the fastener 20 extending out from the grip 12 may be passed through the aperture 26 located adjacent the end of the bracket 14 and the threaded nut 30, or other such securing mechanism, may be threaded onto the fastener 20 so that the handle grip 12 may be rotatably secured to the adjustable slide bracket 14. It is to be understood that the grip 12 may be rotatably attached or otherwise secured to the slide bracket 14 in any other variety of manners and should not be limited to that shown or described herein. For example, the grip 12 may be secured to the bracket 14 by a rivet, by a short threaded rod integrated with the grip 12 and extending from the grip 12, or the like.
The overall length of the handle assembly 10 may be adjusted by any appropriate means, such as by selectively securing the crank bar 16 to the adjustable slide bracket 14. For example, the adjustable positioning of the crank bar 16 relative to the slide bracket 14 may be facilitated by the pair of slots 22, 24 in the slide bracket 14. The fastener or bolt 18 may be used to secure the crank bar 16 to the bracket 14 via the first slot 22 (
The overall length of the handle assembly 10 may generally be longer when the crank bar 16 is secured to the bracket 14 via the first slot 22 (
In addition, within each slot 22, 24 the overall length of the handle assembly 10 may be further adjusted by sliding the bolt 18 along the length of the slot 22, 24, such as to the left or right (relative to
For example, the aperture 40 may be located at the approximate midpoint of the first slot 22 (
In another example, the aperture 40 in the second linear portion 34 of the crank bar 16 may be positioned so that it may be approximately at the midpoint of the second slot 24 (
The handle assembly 10 may be arranged so that the bracket 14 may slide relative to the crank bar 16 by loosely threading the nut 42 onto the bolt 18. The bracket 14 may be rigidly fixed with respect to the crank bar 16 by the application of torque to the nut 42 or bolt 18 to sufficiently tighten the nut 42 onto the bolt 18. It is to be understood that to alter the overall length of the handle assembly 10 the nut 42 and bolt 18 combination may be loosened so that the adjustment bracket 14 may be slid relative to the crank bar 16.
For example, the handle assembly 10 may be arranged so that when the crank bar 16 is secured through the first slot 22 of the adjustable slide bracket 14, the overall length of the handle assembly 10 may be adjusted between any appropriate lengths, such as between approximately 9 inches and approximately 11 inches. The handle assembly 10 may also be arranged so that when the crank bar 16 is secured through the second slot 24 of the adjustable slide bracket 14, the overall length of the handle assembly 10 may be adjusted between any appropriate lengths, such as between approximately 6 inches and approximately 8 inches.
In such an arrangement, the overall length of the handle assembly 10 may be selectively varied between approximately 6 inches and approximately 11 inches. It is to be understood that a handle assembly may be arranged to accommodate adjustments over a wide range of overall lengths and should not be limited to those shown and described herein. For example, the slots 22, 24 in the adjustable slide bracket 14 may be increased or decreased in length, the number of slots 22, 24 in a slide bracket 14 may be increased or decreased, the length of the bracket 14 or crank bar 16 may be increased or decreased, additional apertures 40 may be formed in the crank bar 16 to increase the number of locations at which the crank bar 16 may be secured to the bracket 14, and the like.
In addition, while the handle assembly 10 is shown and described herein as being adjustable via slots 22, 24, it is to be understood that the handle assembly 10 may be adjustable via any other appropriate means, such as a via a ratcheting mechanism and the like, and should not be limited to that shown and described herein.
The adjustable handle 10 may be used with any appropriate type of apparatus, such as with winches or jacks, whereby the overall length of the handle 10 may be adjustable. Such arrangements may allow winch and jack handles 10 to be selectively shortened or lengthened to accommodate different winches or jacks or to accommodate different applications for a specific winch or jack. For example, when a winch is utilized to move large or heavy cargo, a relatively large force may be needed to pull or otherwise move the cargo onto a trailer.
The length of the handle 10 may be increased to increase the force applied to the cargo to move or maneuver the cargo. The lengthening of the handle 10 may provide a longer lever arm, thus, allowing the winch operator to apply a greater pulling force on the cargo without substantially increasing the effort put forth by the operator to rotate the handle 10. Similarly, when a jack is utilized to support a trailer that is holding a heavy load, a relatively large force may be needed to raise the trailer to a horizontal position. The length of the handle 10 may be increased to increase the force applied to the trailer when the jack operator rotates the handle 10. Such an arrangement may assist the jack operator in raising and lowering a trailer.
In another example, a winch may be situated in a position that offers limited space around the winch, and thus, offers limited clearance for the handle 10 to be rotated. In such an arrangement, the handle 10 may be shortened to accommodate rotation of the handle 10 within the tight space or limited clearance without the handle 10 interfering with surrounding objects or surfaces. Similarly, a jack situated in a position with limited space and clearance may utilize a shortened handle 10 to operate in the limited space and clearance.
Arranging a handle 10 for a winch or jack so that the overall length of the handle 10 may be adjustable provides for greater flexibility in manufacturing and inventorying of such handles 10. For example, an adjustable winch or jack handle 10 may reduce the number of variations or types of non-adjustable handles that must be produced to satisfy the need for the numerous applications of winch and jack handles. In addition, adjustable handles 10 may reduce the number of variations or types of non-adjustable handles that must be inventoried by a manufacture or distributor to satisfy the need for the numerous applications of winch and jack handles.
Although the embodiments have been illustrated in the accompanying drawings and described in the foregoing detailed description, it is to be understood that the present application or claims are not to be limited to just the embodiments disclosed, but that the disclosed apparatus may be capable of numerous rearrangements, modifications and substitutions without departing from the scope of the claims hereafter.
This application claims benefit from U.S. Provisional Patent Application No. 61/201,543, entitled “Adjustable Handle For Winch And Jack,” filed on Dec. 11, 2008, which is hereby incorporated in its entirety by reference.
