DETAILED DESCRIPTION

[0021] It is understood that in the drawings, not all reference numbers are included in each drawing for the sake of clarity. In addition, positional terms such as upper, lower, raised, front, back, side, rear, above, below, etc., refer to the apparatus when in a use orientation as shown in the drawings. The skilled artisan will recognize that the relative and absolute positioning of certain elements of embodiments of the apparatus in accordance with the present disclosure can and will assume different orientations when in use.

[0022] Referring now to the drawings, the present disclosure includes embodiments of an apparatus arranged and configured for lifting a pallet, skid, and/or cart. FIG. 1 illustrates a first embodiment of a lifting apparatus with the lifting forks in a lowered position. A crank handle 1, is turned in a clockwise fashion to raise and counter-clockwise to lower the forks. It is attached to a winch 2, which can be locked into position to prevent inadvertent lowering. A cable 14, which is attached to the winch on one end and the fork housing apparatus 13, and on the other end is embedded into the upper frame 10 and runs around pulleys and/or guides preferably located within the fork housing and upper frame 10. The adjustable forks 7 are attached to the fork housing 13 with grooves and notches and the width between the left and right forks can be adjusted to small, e.g., 1-inch increments.

[0023] The winch and pulley housing/mount 11 comprises part of the upper frame and provides added structural support to the overall apparatus. There are handles 3 on both sides of the apparatus which are used in moving it by a pulling or pushing motion from the operator. This motion is supported by front casters 5 (which are mounted on a lower portion of the frame and may provide a locking function) and back casters 8 which are housed inside the lower frame 9. A spring-loaded or otherwise biased cross bar 4 provides support to the overall apparatus and, during operation, may be depressed and locked in a lower position that will allow a pallet or cart to be moved over the cross bar 4 and placed under the load supported by the raised forks. This bar is released from its lowest position when the operator activates the release footswitch 6 or other release mechanism.

[0024] In some embodiments, the manual lifting mechanism including the winch, pulley and cable system may be replaced partially or completely with hydraulic, pneumatic, electric, and/or other mechanical mechanisms efficient systems.

[0025] Referring to FIG. 2, the illustration demonstrates the apparatus in a raised position. The cross support bar 30 is in the lowered and locked position. This will permit the operator to position another pallet and/or cart underneath it. The hand crank 32 has been rotated clockwise to lift and lock the fork housing and forks. The forks 31 are shown to be in their highest raised position and parallel with the fixed winch housing 33.

[0026] An operator 34 will typically operate the apparatus from a position at the front of the apparatus, a position that provides access to all controls, handles, cranks, locks, and releases, while the load(s) are handled on the opposite side of the apparatus.

[0027] Referring to FIG. 3, the illustration demonstrates the positioning of a pallet of implements underneath the apparatus from the front using a conventional pallet jack.

[0028] Some embodiments of the apparatus include a frame comprising an upper frame 10, which supports the lift mechanism in the pallets, and a lower frame 9 provides a lateral extension of the apparatus and supports the wheels/casters/rollers 5, 8 that will allow the apparatus to move across the work floor. Depending on the application, one or more of the wheels/casters/rollers 5, 8 may be fixed, may provide limited horizontal rotation, or may provide for a full 360 rotation to allow the operator to effectively move in position the apparatus. Similarly, depending on the application, one or more of the wheels/casters/rollers 5, 8 may be selectively lockable/releasable so that the apparatus remained in a desired location.

[0029] Some embodiments of the apparatus may be provided with stabilizing elements including, for example, the rear cross bar 4. Additional stabilizing elements may be provided on the apparatus frame, particularly for applications that may require lifting heavy or unbalanced loads. These stabilizers may be arranged and configured with arms that can swing out and/or down from the frame and contact the floor in order to provide additional support. The terminal ends of the stabilizers may include one or more adjustable feet connected to toothed slides or screws that will allow for fine adjustment of the positioning of one or more of the feet.

[0030] As illustrated in FIG. 4A, a vertical pivot joint 20 is provided on, for example the upper frame 10. A support arm 22 extends from the pivot joint and terminates in a fixture 24 that provides for adjustment of a support rod 26 on which is provided a foot 28. As illustrated in FIG. 4B, support arm may be pivoted from a position adjacent the upper frame to a use position in which the foot is extended away from the upper frame. The support rod 26 may then be adjusted as necessary to place the foot 28 on the floor and provide additional stability to the entire apparatus. As will be appreciated by those skilled in the art, the support mechanisms will typically be provided on both sides of the apparatus and may also be provided or attached to the lower frame 9.

[0031] As illustrated in FIG. 5A, a horizontal pivot joint 50 is provided on, for example the upper frame 10. A support arm 52 extends from the pivot joint and terminates in a fixture 54 that provides for adjustment of a support rod 56 on which is provided a foot 58. As illustrated in FIG. 5B, support arm may be pivoted from a position adjacent the upper frame to a use position in which the foot is extended away from the upper frame. The support rod 56 may then be adjusted as necessary to place the foot 58 on the floor and provide additional stability to the entire apparatus. As will be appreciated by those skilled in the art, the support mechanisms will typically be provided on both sides of the apparatus and may also be provided or attached to the lower frame 9.

[0032] As illustrated in FIG. 6, in some embodiments of the apparatus, a single pair of lifting forks 7 is provided for lifting a first load L1 to an upper storage position thereby creating storage space below the first load in which a second load L2 can be deposited. Although as shown in FIG. 6, the second load is resting on the ground, the apparatus may be configured whereby a pallet jack or cart (not shown) carrying the second load L2 may be parked, thereby increasing the available storage without increasing the storage footprint.

[0033] As illustrated in FIG. 7, in some embodiments of the apparatus, a single pair of lifting forks 7 is provided for lifting a first load L1 to an upper storage position thereby creating storage space below the first load in which a second load L2 can be deposited. The apparatus in FIG. 7, however, includes a secondary support structure 76 that can support the second load without the need for the use of a pallet jack or cart (not shown), thereby freeing up those tools for use with other loads and allowing both the first and second loads to be carried by the apparatus.

[0034] As illustrated in FIG. 8, in some embodiments of the apparatus, a first pair of lifting forks 7 is provided for lifting a first load L1 to an upper storage position thereby creating storage space below the first load in which a second load L2 can be deposited. The apparatus in FIG. 8, however, includes a second pair of lifting forks 77 that can be used to lift and support support the second load without the need for the use of a pallet jack or cart (not shown) to position the second load, thereby freeing up those tools for use with other loads and allowing both the first and second loads to be carried by the apparatus.

[0035] The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting thereof. Although one or more embodiments of the invention have been described, persons of ordinary skill in the art will readily appreciate that numerous modifications could be made without departing from the scope and spirit of the disclosed invention. As such, it should be understood that all such modifications are intended to be included within the scope of this invention. The written description and drawings illustrate the present invention and are not to be construed as limited to the specific embodiments disclosed.
