In the illustrated embodiment, there are three engagement teeth 112 for each display attachment slot 110. There are two display attachment slots 110 for each side 38. There may be a different number of engagement teeth 112 in other embodiments of the display attachment slots 110.
Product display attachment points further include display attachment slots 118. The display attachment slots 118 are diamond shaped. There are three display attachment slots 118 on each side of the hand access hole 60. The respective display attachment slots 118 are grouped together in a triangular pattern.
As noted above, the fractional plastic pallet 20 is reparable. The pallet support legs 40 are formed separate from the top deck 30, with the top deck 30 being detachable from the pallet support legs 40 for pallet repair. Snap pins, for example, may be used to secure each pallet support leg 40 to an underside of the top deck 30. Alternatively, attachments other than snap pins may be used, as readily appreciated by those skilled in the art. If the fractional plastic pallet 20 is damaged, anyone of the pallet support legs 40 and the top deck 30 may be replaced as needed.
Each pallet support leg 40 has a center leg section 42 and a pair of leg extensions 44 extending from the center leg section 42. The center leg section 42 and the pair of leg extensions 44 are monolithically formed. The center leg section 42 is secured to the top deck 30 while the leg extensions 44 provide pallet stability.
Each center leg section 42 is spaced from the sides 36, 38 of the top deck 30. This advantageously allows four way entry with pallet handling equipment 150, as illustrated in
Each pallet support leg 40 has a length within a range of 75% to 95% of the length of the top deck 30, and a width within a range of 10% to 20% of a width of the top deck 30. The overall length and width of the pallet support legs 40 provide stability for the pallet 20. Also, a length of each center leg section is within a range of 30% to 40% of an overall length of each pallet support leg 40.
As noted above, the fractional plastic pallet 20 may be sized such that the top deck 30 has a length of 24 inches and a width of 20 inches. An example length of the pallet support legs 40 may be 20.4 inches and an example width of each pallet support leg 40 may be 2.95 inches. An example length of the center leg section 42 may be 5.28 inches.
In addition, the fractional plastic pallet 20 is stackable with other fractional plastic pallets 20, as illustrated in
More particularly, the pallet 20 includes a top deck 30 that includes a product support surface 32 and an opposing underside 34, and with the product support surface 32 including a pair of pallet support leg receiving areas 160. A pair of pallet support legs 40 is on the underside of the top deck 30 and is aligned with the pallet support leg receiving areas 160. By having the pallet support legs 40 engaging or interlocking with the pallet support leg receiving areas 160 stability is provided as stacked fractional plastic pallets 20 are moved.
The illustrated pallet support leg receiving areas 160 are recessed within the product support surface 32 of the top deck 30, as illustrated in
The grid pattern of spaced apart square protrusions 162 is for engaging a corresponding grid pattern of spaced apart square protrusion openings 172 on the underside 170 of each pallet support leg 40, as shown in
Another feature of the fractional plastic pallet 20 is directed to shrink wrap gripping members 180 used with the application and retention of shrink wrap over a product being carried by the top deck 30. Shrink wrap is commonly used to secure a product to a pallet. This is often an alternative to banding, although both can be applied if desired.
A problem encountered in applying shrink wrap to a pallet is in securing the ends of the shrink wrap. This problem is encountered both at the start and the finish of shrink wrapping since the wrap might not want to adhere to the product or the pallet, or may fail to retain itself against the product of the pallet at the end.
Referring now to
The shrink wrap gripping members 180 take the form of a two-sided groove, similar to the shape of an anvil. The two-sided groove has a front recess 182 and a rear recess 184 and a narrowed opening 186. The narrowed opening 186 allows the shrink wrap to be located into the groove, but makes it harder for it to come out again. The wrap can be pulled into either the front or rear recesses 182, 184, and can secure an end of the wrap either at the start or at the end of the wrapping process.
The bottom edge of the top deck 30 includes grooves 190 for use as a banding strap locator, as illustrated in
The top deck 30 includes a hand access hole 60. In the illustrated embodiment the hand access hole 60 is located at or towards the center of gravity of the fractional plastic pallet 20, or at or near the center of the product support surface 32. In other embodiments, there may be a pair of hand access holes 60. The pair of hand access holes 60 may be centered within the top deck 30. Alternatively, the hand access hole 60 is optional such that in other embodiments of the top deck 30 a hand access hole will not be included.
The hand access hole 60 provides an easy means for an operator to handle the fractional plastic pallet 20. The hand access hole 60 is sized large enough for a user to insert all four fingers of his hand therethrough. By providing the central hand access hole 60 towards the center of the fractional plastic pallet 20, or at or near the balance point of the fractional plastic pallet 20, the pallet 20 can very easily be grasped by the user for carrying it or for unloading it from a stack of pallets.
Finger grip details can be provided on one or both long sides of the hand access hole 60. A rounded end wall may be provided at one or both short ends thereof. A rounding of the finger grips or ends of the hand access hole 60 offers a smother engagement surface to the user. This also can make the fractional plastic pallet 20 more comfortable when being lifted.
The top deck 30 is formed using ribbing grids 200, as illustrated in
In addition, the product support surface 32 of the top deck 30 includes an array of frictional points 31 to prevent slippage of products on the product support surface 32. Each frictional point 31 has a circular shape and is in the form of a raised stub, for example.
The fractional plastic pallet 20 also includes a ridge 39 that extends along the corners of the pallet. The ridge 39 is at the lower edge of sides 36, 38. The corners are configured so that they are recessed from the ridge 39, as shown in
A method for making the above illustrated pallet 20 includes forming a top deck 30 that includes a product support surface 32 and an opposing underside 34, and with the product support surface 32 including a pair of pallet support leg receiving areas 160.
The method further includes forming a pair of pallet support legs 40. Each pallet support leg 40 includes a center leg section 42 and a pair of leg extensions 44. The center leg section 42 has a first end and a second end opposite the first end. The pair of leg extensions 44 extend outwards from the second end of the center leg section 42. An underside of the center leg section 42 and the pair of leg extensions 44 is configured to engage one of the pallet support leg receiving areas 160 of an identical pallet when stacked thereon.
The method further includes coupling the first ends of the center leg sections 42 of the pair of pallet support legs 40 to the underside of the top deck 30. Each pallet support leg 40 is aligned with a corresponding pallet support leg receiving area 160 in the top deck 30.
