DETAILED DESCRIPTION OF THE INVENTION

Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

In various exemplary embodiments, the technology described herein provides a materials safety cage and associated methods. The safety cage assembly is configured for transport by both a crane and a forklift. Additionally, the technology described herein provides a masonry materials safety cage for lifting with a crane, forklift, or the like.

Referring now to FIGS. 1 through 4, a safety cage assembly 100 is shown. FIGS. 1 through 4 represent the same safety cage assembly 100 in front perspective, front and back, side, and top views, respectively. The safety cage assembly 100 includes a cage 102 and a base 104. The safety cage assembly 100 is configured for storage, distribution, transportation, and handling of various goods in a pallet area 200 (FIGS. 2, 3, and 4) secured by the safety cage assembly 100. By way of example, the safety cage assembly 100 is utilized for moving masonry materials. The cage 102 has four vertical sides generally connected in a generally rectangular shape. The base 104 is configured to receive upon a top surface of the base 104 a load-bearing pallet, or the like, wherein the pallet is loaded with goods. The cage 102 is lowered upon the base 104, to attach, engage, and secure, the cage 102 to the base 104 for safe transportation of the pallet of goods.

The same safety cage assembly 100 includes a plurality of vertical corner rails 106. Each vertical corner rail 106 connects two ends of the vertical sides of the cage 102. Each vertical corner rail 106 is configured to provide structural support to the cage 102. Each vertical corner rail 106 has a leg for connectivity to the base 104. The same safety cage assembly 100 also includes a plurality of vertical side rails 108. Each vertical side rail 108 is vertically disposed in a center region of each of the vertical sides of the cage 102, thus configured to provide structural support to the cage 102.

The safety cage assembly 100 also includes a plurality of bottom frame rails 134. The bottom frame rails 134 are connected to the plurality of vertical corner rails 106 near the bottom of the cage 102 and configured to provide structural support to the cage 102. The bottom frame rails 134 are connected together in a generally rectangular shape and integrally formed with the cage 102. The safety cage assembly 100 further includes a plurality of top frame rails 132. The top frame rails 132 are connected to the plurality of vertical corner rails 106 near the bottom of the cage 102. The top frame rails 132 are connected together in a generally rectangular shape and integrally formed with the cage 102.

The safety cage assembly 100 also includes a plurality of top diagonal rails 118. The top diagonal rails 118 are horizontal and diagonal and connect the vertical corner rails 106 opposite one another at a top of the cage 102. The top diagonal rails 118 are configured to provide structural support to the safety cage assembly. Disposed upon each cage top corner, each corner formed at the joint of a vertical corner rail 106 top, pair of top frame rails 132, and top diagonal rail 118, is a gusset 120. The gusset 120 provides additional structure to the cage 102 and various frame members intersecting at each top corner of the cage (i.e., 106, 132, and 118).

Disposed on the top of the cage 102, at the cross-intersection of two top diagonal rails 118, is a platform 124. The platform 124 provides additional structural integrity to the cage 102 and provides support for the lifting of the cage 102. Located upon the platform 124 is a loop opening 122. The loop opening extends upwardly and is configured to receive a hook for lifting and transporting the cage 102.

The safety cage assembly 100 includes a plurality of metal plates 110. Each metal plate 110 is secured to one of the vertical corner rails 106, near the bottom of the rail, with a cage pin 116. Each metal plate 110 includes a handle grip 114 to grip and swing the metal plate 110 as needed for proper alignment with the base 104 and attachment to a base pin 112. A pin slot 202 (FIG. 2) is provided in which the base pin 112 enters and latches downwardly in a secure position.

The safety cage assembly 100 includes a wire mesh 126 disposed around the perimeter of the cage 102. The wire mesh 126 further secures the various rails and frames together and contains a pallet load with the cage 102. Thus, no contents loaded on a pallet contained within the safety cage assembly 100 are allowed to exit. This provides added safety to the safety cage assembly 100.

The base 104 of the safety cage assembly 100 includes a plurality of horizontal support rails 128, 130. The horizontal support rails 128, 130 include a number 130 of the horizontal rails extending from a left side to a right side of the base 104 and a number 128 of the horizontal rails extending from a front to a back of the base 104. The horizontal support rails 128, 130 are configured to provide structural support to the base 104. Alternatively, the horizontal support rails are configured diagonally between the corners of the base 104 to provide structural support to the base 104.

By way of example, a safety cage assembly 100 is manufactured by utilizing two-inch tubular steel. Other durable materials can be utilized so long as very heavy loads are supported. A square perimeter is constructed of the two-inch tubular steel, forming top frame rails 132. A square perimeter is constructed of the two-inch tubular steel, forming bottom frame rails 134. The rails 132 are integrally formed to each other, such as by welding. The rails 134 are integrally formed to each other, such as by welding. The square perimeters can, for example, measure fifty four inches measured from the outside of the frame and fifty two inches from the inside. The square perimeters can be strengthened by utilization of gussets 120 at the corners. The gusset 120 is, for example, a quarter-inch steel plate gusset. The top diagonal rails 118 can also be constructed from two-inch tubular steel connecting. The top diagonal rails 118 form an “X” shape across the integrally formed top frame rails 132. At the cross-section of the top diagonal rails 118, where the top diagonal rails 118 intersect in the “X,” a platform 124 is welded, or otherwise integrally formed, to maintain the top of the cage 102 and to support a loop opening 122. The loop opening 122 can be formed, for example, by utilizing a one-inch eye bolt having a six-inch opening to receive a crane hook, or the like. The eye bolt can be welded to the platform 124. The vertical corner rails 106 opposite one another can also be constructed of two-inch tubular steel, connecting, and integrally formed with, the top and bottom square perimeters. The vertical corner rails 106 are, for example, sixty inches in length. At approximately four inches above a base of each vertical corner rails 106 the bottom square perimeter is welded, or otherwise integrally formed, to the vertical corner rails 106. The remaining four inches below the weld creates “legs” for placement in the base 104. Within the bottom square perimeter constructed of the bottom frame rails 134, one-inch holes, for example, are drilled at each corner, configured to receive one-inch bolts, or pins, on which a half-inch, oval-shaped metal plate 110 is placed. The metal plate 110 is configured with two holes, one hole configured with a pin slot 202, so that another one-inch bolt, or pin, can pass through and slide down into the pin slot 202 to latch securely. The pallet base 104 similarly is constructed of two-inch tubular steel. The pallet base 104 is also fitted with corner receivers to accommodate the legs of the cage 102 as the cage 102 is lowered upon the base 104. The pallet base 104 is, for example, fitted with five inch by five inch angled steel feet, integrally formed with the base 104. In operation the cage 102 can be removed entirely from the base 104 in a vertical position, eliminating the need for additional work space.

Referring now to FIG. 5, the safety cage assembly 100 is depicted in use with a crane 500 and crane hook 502. Utilizing a crane 500 and crane hook 502 enables the cage 102 of the safety cage assembly 100 to be lifted above the base 104. By way of example, pallet area 200 is shown with a load of masonry blocks 504. A pallet of blocks 504 has been placed upon the base 104, by a forklift of the like. The crane 500 lowers the crane hook 502 holding the cage 102 over the loaded pallet and received at the base 104 by the corner receivers 506. A corner receiver 506 is located at each corner of the base and is configured to receive a leg from the vertical corner rails 106 of the cage 102. The cage 102 is secured to the base 104 with the metal plates 110, pin slots 202, and base pins 112. Once secured, the pallet of blocks 504 can be transported safely and securely. Once transported, the metal plates 110 and base pins 112 are released, allowing the cage 102 to be removed from the base 104 and pallet of blocks 504.

Referring now to FIGS. 6 and 7, close up views of the metal plate 110, cage pin 116, and base pin 112, with the cage 102 engaged to the base 104 (FIG. 6) and with the cage 102 disengaged from the base 104 (FIG. 7), all of the safety cage assembly 100, are shown. Each metal plate 110 includes a handle grip 114 to assist with alignment of the cage 102 to the base 104. Additionally, each metal plate 110 includes a pin slot 202 to receive the base pin 112.
