DETAILED DESCRIPTION OF THE INVENTION

(19) Various embodiments of the present invention are described and shown in the accompanying materials, descriptions, instructions, drawings, and photographs. For purposes of clarity in illustrating the characteristics of the present invention, proportional relationships of the elements have not necessarily been maintained in the drawings and photographs. It will be appreciated that any dimensions included in the drawings are simply provided as examples and dimensions other than those provided therein are also within the scope of the invention.

(20) The description of the invention references specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The present invention is defined by the appended claims and the description is, therefore, not to be taken in a limiting sense and shall not limit the scope of equivalents to which such claims are entitled.

(21) One objective of the present invention is to provide a quick release mounting mechanism for mounting an attachment, such as a fork or other tool, to a forklift or other piece of industrial and construction equipment. One embodiment of the present invention is designed to (a) provide a means for lockably mounting an attachment to a carriage or lifting actuator that requires less human operation, (b) allow for a wide array of lifting equipment to connect and integrate, in a simple and cost-effective manner, with existing industrial and construction equipment without sacrificing loading capacity of the overall assembly, and (c) eliminate the need for complex devices and systems to retrofit existing industrial and construction equipment.

(22) FIG. 1 depicts one of the most common pieces of industrial and construction material-moving equipment known in the art, a forklift 10. Forklifts 10 are widely used in factories and warehouses for moving objects which are loaded on a pallet (not shown), for example. Forklifts 10 generally comprise a motorized vehicle portion 20, a lift portion 30, a loading system 40, and elongated forks 50. The lift portion 30 of traditional forklifts 10 is vertically movable up and down by an operator of the forklift 10. The lift portion 30 commonly includes a mast 32, an actuator (not shown) that can be powered by a hydraulic cylinder (not shown), a lift carriage 34, and elongated forks 50 that extend outward from the front of the forklift 10.

(23) FIG. 2 depicts a loading system 40 for a forklift (not shown), generally comprising a pair of forks 50 attached to a lift carriage 34, as is known in the art. The forks 50 of the loading system 40 may be dimensioned to be received by a pallet (not shown), and this enables the forks 50 to, when raised along the mast 32 of the lift portion 30 of the forklift 10, as shown in FIG. 1, relative to the ground, lift the pallet and its associated contents. The lift carriage 34 may take many different forms, as will be recognized by those of ordinary skill in the art, but generally comprises an at least one structural cross bar 36, 38 extending in a lateral direction. As shown in FIG. 2, a first, upper cross bar 36 may support the forks 50. As further shown in FIG. 2, a second, lower cross bar 38 may be included to resist the rotational forces of the fork 50 relative to the first, upper cross bar 36. Although FIG. 2 depicts the forks 50 being supported on the first, upper cross bar 36, it will be understood that it is possible for the second, lower cross bar 38 to support the forks 50 in the same or similar manner. Given that substantial load will normally be supported by the cross bars 36, 38, each cross bar 36, 38 is preferably made of solid steel or other metal which is sufficiently strong to bear the loads that are likely to be encountered thereby. The elongated forks 50, when attached to the at least one cross bar 36, 38, extend away from the lift carriage 34 and the at least one cross bar 36, 38.

(24) As shown in FIG. 3, the forks 50 are preferably substantially L-shaped having a substantially vertical portion 52, with a distal end 54, and a substantially horizontal portion 56 separated by a bend or heel 58. A mounting mechanism 60 is attached to the distal end 54 of the vertical portion 52 of the fork 50. The mounting mechanism 60 generally comprises a hook portion 62 and locking mechanism 80a. The hook portion 62 is adapted for receiving an at least one cross bar (now shown) of a carriage (not shown) and the locking mechanism 80a secures the fork 50 to the at least one cross bar.

(25) FIGS. 4-7 illustrate previously known locking mechanisms 80a, 80b of mounting mechanism 60 adapted for attaching forks (partially shown) to an at least one cross bar (not shown). FIGS. 4 and 5 illustrate a pin locking mechanism 80a in which a fastening device 90, such as a pin, screw, or a retractable plunger, may be manually selectively tightened or loosened, which enables an operator to selectively and securely connect and disconnect the attachment (partially shown) to a lift carriage (not shown). As best shown in FIG. 5, the pin locking mechanism 80a fastening device kit 90 generally comprises a bolt 92, a spring 94, and a mushroom cap 96. FIGS. 6 and 7 illustrate another locking mechanism 80b fastening device generally comprising, as best shown in FIG. 7, a bolt 92, a spring 94, a handle 100, and a pin 102. Locking mechanism 80b can be generally operated in a similar manner to locking mechanism 80a to achieve the same result. Therefore, as demonstrated in FIGS. 4-7, typical detachable attachments (partially shown) can be manually connected and disconnected to the lift carriage, which requires an operator to engage and disengage the locking mechanisms 80a, 80b.

(26) FIGS. 8-13 depict perspective views of an improved mounting mechanism 60 according to one embodiment of the present invention. The improved mounting mechanism 60 may generally comprise an improved hook portion 62 and an improved locking mechanism 80. The hook portion 62 may comprise a proximal end 64 affixed or otherwise attached to an attachment (partially shown) and a free distal end 66 that generally defines a generally vertical section 68. In one embodiment, the improved locking mechanism 80 can be attached to the distal end 66 of the hook portion 62. Although FIGS. 8-13 depict the proximal end 64 of the hook portion 62 as being affixed or otherwise attached to a lateral face of the attachment, it will be appreciated that the hook portion 62 and the proximal end 64 thereof can be designed, arranged, and configured so that the proximal end 64 can be affixed or otherwise attached to various faces of the attachment, including, without limitation, a top face of the distal end of the partially depicted attachment or the bottom face of a hook-shaped distal end of the attachment (not shown).

(27) The hook portion 62 may define an opening 70 between the distal end 66 and/or the generally vertical section 68 and the attachment. The at least one cross bar (not shown) fixedly attached to a lift carriage (not shown), or other suitable member, may be selectively inserted in the opening 70 of the improved mounting mechanism 60 without removing or moving elements of the lift carriage. Further, it will be appreciated that the improved hook portion 62 will be made of material at least sufficient to withstand vertical forces commonly demanded in the industrial and construction industry. Further, as best illustrated in FIG. 10, the generally vertical section 68 of the hook portion 62 of the improved mounting mechanism 60 may comprise a recess 72.

(28) The improved locking mechanism 80 may comprise a pivotable latch member 82, a pin 84, and one or more magnets 86, wherein the latch member 82 may be selectively and adjustably biased to a closed or opened position or orientation by the forces of one or more of the magnets 86. The recess 72 of the vertical section 68 may be capable of fully or partially receiving the latch member 82 or any portion thereof; for example, this would include a second section 112 of the latch member 82 when the latch member 82 is positioned in the open orientation. In FIGS. 8-10, the latch member 82 is illustrated as being positioned in a closed position or orientation. In FIG. 11-14, the latch member 82 is illustrated as being positioned in an open position or orientation.

(29) As best shown in FIGS. 8-14, the pivotable latch member 82 can be selectively and adjustably biased in either the open orientation or the closed orientation by forces acting upon the latch member 82 relative to a fulcrum or pivot point, which can be a pin 84 pivotably coupled thereto. The pin 84 of the improved locking mechanism 80 may be disposed in or around the improved hook portion 62 proximate the distal end 66 thereof. In one embodiment, the pin 84 may be located in a position so that when the latch member 82 is in a closed orientation (see FIGS. 8-10 and 15-16), as best illustrated in FIG. 15, the center of center of gravity of the latch member 82 is located in front ofor, relative to the configuration depicted in FIG. 15, to the left ofthe center axis of the pin 84, thereby keeping the latch member 82 in its closed orientation under the force of gravity. Further, as discussed in further detail below, a magnet 86 may optionally be provided to further selectively retain the latch member 82 in its closed position or orientation. Similarly, the pin 84 may likewise be located in a position so that when the latch member 82 is in an open orientation (see FIGS. 11-14), the center of center of gravity of the latch member 82 is located behind the center axis of the pin 84, thereby keeping the latch member 82 in its open orientation under the force of gravity. Again, a magnet 86 may optionally be provided to further selectively retain the latch member 82 in its open position or orientation.

(30) It will be understood that a magnet 86 can be used to selectively retain the latch member 82 in an open orientation or closed orientation through attracting magnetic forces or repelling magnetic forces. For example, in the closed orientation, the magnet 86 can be adapted to magnetically attract a first section 110 of the latch member 82 and/or repel a second section 112 of the latch member 82. Further, in the open orientation, the magnet 86 can be adapted to magnetically attract a second section 112 of the latch member 82 and/or repel a first section 110 of the latch member 82. Accordingly, the forces acting on the latch member 82 to retain it in a desired orientation can include magnetic forces, gravitational forces, spring forces, other suitable forces, or any combination thereof. Preferably, the forces acting upon the latch member 82 to bias its orientation can be overcome, so as to influence the orientation of the latch member 82 relative to its biased orientation, by the application of opposing rotational forces relative to the pin 84 that are at least non-negligible. It will be appreciated that the counteracting nature of opposing forces acting on the latch member 82 may allow for the latch member 82 to be balanced in a manner that it may be disturbed from its biased position with at least a non-negligible disturbing force.

(31) FIGS. 11-12 best illustrate the use of a magnet 86 with the improved mounting mechanism 60 as a means for biasing the pivotable latch member 82 according to one embodiment. It will be understood that, in one embodiment, the magnet 86 may be a neodymium magnet made from an alloy of neodymium, iron, and boron. It will be appreciated, however, that the magnet 86 can be any magnet and may be made of any magnetic material, including any combination diamagnetic, paramagnetic, ferromagnetic, and antiferromagnetic materials. The magnet 86 may alternatively be an electromagnet. In another embodiment, the latch member 82 may, but need not, include an additional, complementary magnet (not shown) positioned to couple with the magnet 86 or the hook portion 62. In an additional embodiment, wherein the magnet 86 is coupled with the complementary magnet, the magnet 86 may be capable of selectively reversing polarity so that it is capable of selectively attracting or repelling the complementary magnet. In another embodiment, a magnet is not provided on the vertical section 68, but one or more magnets are provided on the first section 110 and/or second section 112 of the latch member 82.

(32) In one embodiment, as best illustrated in FIG. 13, when the latch member 82 is in the open orientation and the latch member 82, or any portion thereof, is received in the recess 72 of the vertical section 68 of the hook portion 62, the latch member 82, or the portion thereof received in the recess 72, can be substantially flush or coplanar with the surrounding hook portion 62 while also further defining the opening 70 between the generally vertical section 68 of the hook portion 62 and the attachment (partially shown) in conjunction with the surrounding hook portion 62. In other embodiments (not shown), the second section 112 of the latch member 82 may be fully received within the recess 72 such that it is set back from the inner surface of the vertical section 68.

(33) As shown in FIG. 14, the latch member 82 may be L-shaped and can include a first section 110 and a second section 112 extending generally perpendicularly from a central bend portion 114. As best shown in FIG. 15, the length L of the second section 112 (as measured from a center axis of the pin 84 to the distal end of the second section 112) may be such that the second section 112 extends at least partially into the opening 70 of the hook portion 62 when the latch member 82 is in its closed orientation. In another embodiment, the length L of the second section 112 (as measured from a center axis of the pin 84 to the distal end of the second section 112) may be such that the second section 112 extends entirely into the opening 70 of the hook portion 62 when the latch member 82 is in its closed orientation, such that the distal end of the second section 112 flushly engages the portion of the attachment or the hook portion 62 directly opposite of the latch member 82. In one embodiment, the length L of the second section 112 is equal to or less than the width W of the opening 70 combined with the thickness T between the center axis of the pin 84 and the closest inner edge of the improved hook portion 62 defining the opening 70. Similarly, the length L of the second section 112 should be such that a second section 112 may pass by the at least one cross bar 36, 38 when the latch member 82 is rotated between closed and open orientations, and vice versa. In one embodiment, the length L of the second section 112 is equal to or less than the distance D between the center axis of the pin 84 and the at least one cross bar 36, 38.

(34) Further, as partially illustrated in FIGS. 12 and 14, the second section 112 of the latch member 82 may comprise an area 116 of optionally reduced thickness at or near its distal end. As best illustrated in FIG. 14, this optionally reduced thickness of the second section 112 may be used to assist with receiving the latch member 82, or any portion thereof, into the recess 72 of the hook portion 62 of the improved mounting mechanism 60.

(35) FIG. 15 illustrates an improved mounting mechanism 60 engaged by and receiving an at least one cross bar 36, 38 with a generally circular cross section. It will be appreciated that the received cross bar 36, 38 may have any suitable cross sectional shape. In one embodiment, the attachment (partially shown) may be mounted to the equipment via the improved mounting mechanism 60 in such a manner that the attachment may be pivotally mounted relative to the cross bar 36, 38such that the attachment can freely rotate about the pivot point defined by the cross bar 36, 38. In another embodiment, the attachment may be mounted such that it is generally fixed and restricted from rotating relative to the cross bar 36, 38 or a carriage (not shown). It will be appreciated that the improved mounting mechanism 60 may be adapted for permitting an attachment to be moved laterally (e.g., forks may be moved laterally in order to adjust the spacing between the forks). It will also be understood that, in one embodiment, the improved mounting mechanism 60 may be designed to restrict both the lateral and the rotational movement of the attachment or attachments.

(36) Further, as best illustrated in FIG. 15, in conjunction with the hook portion 62, the latch member 82 may lockably retain and serve to ensure that the at least one cross bar 36, 38 does not disengage from the attachment in the event that there is an atypical movement overcoming the forces otherwise engaging the at least one cross bar 36, 38 to the hook portion 62. In FIG. 15, the latch member 82 is shown in its biased closed orientation, and because of the counteracting forces acting upon the latch member 82, the received cross bar 36, 38 cannot disengage from the attachment without disturbing the biased latch member 82. In other words, if the received cross bar 36, 38 were to come into contact with the second section 112 of the latch member 82, the latch member 82 would be prohibited from rotating, as the first section 110 of the latch member 82 would be engaged against the vertical section 68, or an outer surface thereof, of the hook 62.

(37) FIG. 16 depicts an improved fork 50 that includes an improved mounting mechanism 60 attached to the distal end 54 of the substantially vertical portion 52 of the fork 50. The improved hook portion 62 of the improved mounting mechanism 60 may be formed as a unitary component with the fork 50. In other embodiments, the improved hook portion 62 may be affixed or otherwise attached to the fork 50, for example, through welds, bolts, pins, or other suitable attachment means. It will be appreciated that a single improved mounting mechanism 60 may be attached to more than one fork 50.

(38) FIG. 17 depicts an improved fork 50 and an improved mounting mechanism 60 according to one embodiment of the present invention. As best illustrated in FIG. 17, the improved mounting mechanism 60 may be substantially as wide as the working face of the elongated fork 50, but it will be appreciated that the improved mounting mechanism 60 can be wider or narrower if required.

(39) In operation, the pivotable latch member 82 may be biased in a closed orientation. Then, when a yet-to-be-received cross member, such as an at least one cross bar 36, 38 or other longitudinal member, interfaces with the pivotable latch member 82 biased in the closed orientation, the latch member 82 can release from its closed orientation. During this release of the latch member 82, the cross member can pass by the pivotable latch member 82 into the opening 70 of the hook portion 62. More specifically, in one embodiment, the improved mounting mechanism 60 is adapted for permitting an attachment to be mounted to a piece of equipment, such as a forklift 10, via the improved mounting mechanism 60 with little to no operator interaction with the improved mounting mechanism 60. In that mounting operation, the carriage 34 may be positioned such that an at least one cross bar 36, 38 is located just beneath the improved mounting mechanism 60. The latch member 82 may be in either a closed orientation or an open orientation. The carriage 34 may then be raised so that the cross bar 36, 38 may be received within the opening 70. If the latch member 82 is in its closed orientation, the cross bar 36, 38 can engage the second section 112 of the latch member 82 thereby rotating the latch member 82 toward an open orientation as the carriage 34 is raised. Once the cross bar 36, 38 has passed by the second section 112 of the latch member 82, the latch member 82 may be rotated back to its closed orientation in order to retain the cross bar 36, 38 within the opening 70. It will be appreciated that, in one embodiment, the latch member 82, when in its closed orientation, may only partially extend into the opening 70 of the hook portion 62 and adequately retain the cross bar 36, 38 within the opening 70. That rotation of the latch member 82 back to its closed orientation may occur automatically as a result of a gravitational force or other force, or may be influenced by an operator.

(40) The process of unmounting an attachment from a piece of equipment, such as a forklift 10, may be equally as simple. In one embodiment, the latch member 82 can rotated from its closed orientation to an open orientation in order to allow the received cross member, such as an at least one cross bar 36, 38 or other longitudinal member, to pass by the latch member 82 and be disengaged from the opening 70. It will be appreciated that the second section 112 of the latch member 82 may be partially or fully recessed and received within the vertical section 68 of the hook 62 via the recess 72, such that the cross member may pass thereby without impediment as it is being lowered through the opening 70. Accordingly, the vertical section 68 of the hook 62 may include a slot, depression, recess 72, or the like defined therein that is suitable for receiving at least a portion of the second section 112 of the latch member 82 when the latch member 82 is in its open orientation. The latch member 82 can be retained in its open orientation as a result of one or more forces, such as a magnetic force, gravitational force, spring force, other suitable force, or any combination thereof.

(41) It will be appreciated that, in one embodiment, the process of mounting or unmounting an attachment from a piece of equipment can be achieved while the improved mounting mechanism 60 is generally perpendicular to the ground via the length of the attachment or while the attachment is generally vertical to the ground.
