With reference now to the drawings, and in particular to
As best illustrated in
A pivoting assembly 12 is coupled to the base member 11. The pivoting assembly 12 is designed for being selectively coupled to the carriage of the forklift whereby the pivoting assembly 12 extends between the base member 11 and the carriage of the forklift. The pivoting assembly 12 is designed for being actuated by a user for pivoting the base member 11 with respect to the carriage of the forklift.
An arm member 13 slidably engages the base member 11 whereby the arm member 13 is selectively extendable from the base member 11. The arm member 13 is designed for engaging an edge of the slab whereby the arm member 13 tips the slab onto the forks of the forklift when the pivoting assembly 12 pivots the base member 11.
The base member 11 comprises a perimeter wall 14. The perimeter wall 14 defines a lumen 15 of the base member 11 extending through the base member 11. The lumen 15 of the base member 11 slidably receives the arm member 13 whereby the arm member 13 is slidably extendable from the lumen 15 of the base member 11.
The arm member 13 comprises an arm portion 16. The arm portion 16 is slidably positioned in the lumen 15 of the base member 11 whereby the arm portion 16 is selectively extendable from the base member 11 for engaging slabs of varying dimensions. The arm member 13 comprises a pick portion 17. The pick portion 17 is coupled to the arm portion 16 whereby the pick portion 17 is positioned opposite the base member 11. The pick portion 17 is designed for engaging a side and edge of the slab for tipping the slab onto the forks of the forklift when the base member 11 is pivoted by the pivot assembly.
An extending assembly 18 is coupled to the base member 11 and the arm member 13. The extending assembly 18 slides the arm member 13 with respect to the base member 11 whereby the extending assembly 18 is for adjusting a length of the arm member 13 extending from the base member 11 when the extending assembly 18 is actuated by the user.
The extending assembly 18 comprises an extending ram 19. The extending ram 19 is coupled to the arm member 13 and the base member 11. The extending ram 19 is designed for being operationally coupled to a hydraulic system of the forklift whereby a length of the extending ram 19 is adjustable for extending and retracting the arm member 13 with respect to the base member 11 when the hydraulic assembly is selectively actuated by the user.
The extending ram 19 comprises an extending piston 20 and an extending cylinder 21. The extending piston 20 is selectively extendable from the extending cylinder 21. The extending cylinder 21 is coupled to the base member 11. The extending piston 20 is coupled to the arm member 13 whereby the arm member 13 is slid with respect to the base member 11 when the extending piston 20 is selectively extended from the extending cylinder 21. The extending cylinder 21 is designed for being operationally coupled to the hydraulic system of the forklift whereby selective actuation of the hydraulic system of the forklift selectively extends and retracts the extending piston 20 with respect to the extending cylinder 21.
The pivoting assembly 12 comprises a pivoting ram 22. The pivoting ram 22 is coupled to the base member 11. The pivoting ram 22 is designed for being coupled to the carriage of the forklift whereby the pivoting ram 22 extends between the base member 11 and the carriage of the forklift. The pivoting ram 22 is designed for being operationally coupled to a hydraulic system of the forklift whereby a length of the pivoting ram 22 is adjustable for pivoting the base member 11 with respect to carriage of the forklift when the hydraulic assembly is selectively actuated by the user.
The pivoting ram 22 comprises a pivoting piston 23 and a pivoting cylinder 24. The pivoting piston 23 is selectively extendable from the pivoting cylinder 24. The pivoting cylinder 24 is designed for being coupled to the carriage of the forklift. The pivoting piston 23 is coupled to the base member 11 whereby the base member 11 is designed for being pivoted with respect to the carriage of the forklift when the pivoting piston 23 is selectively extended from the pivoting cylinder 24. The pivoting cylinder 24 is designed for being operationally coupled to the hydraulic system of the forklift whereby selective actuation of the hydraulic system of the forklift selectively extends and retracts the pivoting piston 23 with respect to the pivoting cylinder 24.
In use, the user actuates the hydraulic system to extend the extending piston 20 from the extending cylinder 21 and thereby adjust the length of the portion extending from the base member 11. The pivoting assembly 12 is then used to pivot the base member 11 so that the pick portion 17 of the arm member 13 is positioned around the side and edge of the slab. The extending assembly 18 and the pivot assembly are used in conjunction to positioned the slab onto the forks of the forklift. When the user is read to deposit the slab on a pallet the user actuates the pivot assembly to pivot the base member 11 with respect to the carriage of the forklift to position the arm member 13 and the base member 11 out of the way of the slab being deposited on the pallet.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
