Abstract

A pivot point for pallets is provided to enable rotation of the pallet rotation about the pivot point when loaded and seated on a floor. The pivot point may be a pressure relief pivot spherical cap or spherical dome that is attached or integrated to a balancing point along an underside of the bottom deck of the pallet.

Claims

1. A pivotable pallet having a single pivot point operatively associated to a balancing point along an underside of the pivotable pallet, wherein the single pivot point protrudes out of plane of said underside so that when the pivotable pallet is along a supporting surface, the single pivot point interfaces with said supporting surface, wherein the single pivot point has an inward facing flat surface directly connected to a central stringer of the pivotable pallet and an outward facing surface defining a spherical dome with a diameter that confines the single pivot point within a profile of the central stringer of the pivotable pallet.

2. The pivotable pallet of claim 1, wherein the single pivot point is molded during formation of the pivotable pallet.

3. The pivotable pallet of claim 1, wherein the single pivot point is a spherical cap.

4. The pivotable pallet of claim 3, wherein the diameter of the spherical cap is between one and a half inches to four inches.

5. The pivotable pallet of claim 4, wherein a height of the spherical cap is between one-sixth of an inch to one inch.

6. A method of improving a pivotability of a pallet, the method comprising attaching a single pivot point of claim 1 to a balancing point along an underside of a central stringer of said pallet.

7. The method of claim 6, wherein the diameter of the spherical cap is between one and a half inches to four inches.

8. The method of claim 7, wherein a height of the spherical cap is between one-sixth of an inch to one inch.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0023] Broadly, an embodiment of the present invention provides a pivot point for pallets that enables their rotation when loaded and seated on a floor. The pivot point may be attached or integrated to a balancing point along an underside of the bottom deck of the pallet.

[0024] Referring to FIGS. 1-8, the present invention may include a pressure relief pivot 10 and 22 for a pallet 14 and 20, respectively. The pressure relief pivot 10 may have a spherical cap or spherical dome geometry, wherein the height of the cap is less than the radius of the associated sphere of the spherical cap/dome. The pressure relief pivot 10 may be solid (spherical dome) through its entire height or may be hollowed out, along its inward facing surface 12, have the shape of a contact lens (spherical cap). The diameter of the spherical cap/dome may be between one-and-a-half inches to four or more inches. A height of the spherical cap/dome may be between one-sixth to one or inches. The term pressure relief connotes that the pivot 10 or 22 interfaces with the supporting surface/floor when the pallet 14/20 is properly placed on said supporting surface/floor, thereby the pivot 10 or 22 carries a substantial amount of the pallet 14/20 weight being located at a balancing point of the pallet 14/20, relieving a substantial amount of the pressure/weight and thus reducing the resulting frictional force applied to a remainder of the underside of the pallet 14/20 so that the pallet 14/20 can easily rotate about the rounded surface of the pivot 14/20.

[0025] The pressure relief pivot 10 may be formed with and by way of liquid resin or other material and manufacturer process (e.g., additive manufacturer) may be utilized, as long as the material and manufacturer process enable the functionality disclosed herein. The pressure relief pivot 10 may be rounded and/or sanded along its outward facing surface 11 to provide a suitable tapered or rounded surface on which to pivot a loaded pallet. In one embodiment, the pressure relief pivot 22 may be a spherical dome that is integrated or molded to be part of a molded pallet 20.

[0026] The pressure relief pivot point 10/22 may be attached or molded to a central bottom point of the pallet 14/20 along an underside thereof. There are many forms of pallets, and the type of pallet that the present invention is applicable with is not limited to those shown in the drawings. In the drawings, the pressure relief pivot point 10/22 is shown attached to an underside of a bottom deck/lower surface member 16/24.

[0027] By central bottom point it is understood that the location of the pressure relief pivot point 10/22 is associated with a surface that would otherwise interface with a supporting surface (e.g., floor), but for the pressure relief pivot 10/22, and wherein this location is a point with respect to which the pallet is balanced with respect to applied forcese.g., the center of mass of a distribution of mass of the pallet in space (sometimes referred to as the balance point) or point at any given time where the weighted relative position of the distributed mass sums to zero.

[0028] The present invention embodies the pressure relief pivot 10/22 operatively associated with the balance point along an underside of a pallet 14/20. Accordingly, during use, in contrast to all the weight flatly distributed along the entirety of the underside of a conventional pallet, making it difficult to spin or rotate a pallet, the operatively associated pressure relief pivot 10/22 reduces the friction, enabling rotation or spinning the pallet 14/20, as illustrated in FIG. 7.

[0029] The present invention embodies a method of improving a pallet 14, through attaching a pressure relief pivot 10 at the balancing point along an underside of the pallet 14, whereby the pallet 14, even loaded with 3000+ pounds, can now be rotated or spun with a small fraction of the force needed (relative to prior art pallets) resulting in little to no damage to the pallets during the lifespan of the pallet in turn extending the lifespan of the pallet, since this is how 95% of all damages to pallets occur.

[0030] Additionally, the present invention may be used in any field of technology moving heavy objects that need to be spun or rotated during any step of the transportation of the product.

[0031] As used in this application, the term about or approximately refers to a range of values within plus or minus 10% of the specified number. And the term substantially refers to up to 80% or more of an entirety. Recitation of ranges of values herein are not intended to be limiting, referring instead individually to any and all values falling within the range, unless otherwise indicated, and each separate value within such a range is incorporated into the specification as if it were individually recited herein.

[0032] For purposes of this disclosure, the term aligned means parallel, substantially parallel, or forming an angle of less than 35.0 degrees. For purposes of this disclosure, the term transverse means perpendicular, substantially perpendicular, or forming an angle between 55.0 and 125.0 degrees. Also, for purposes of this disclosure, the term length means the longest dimension of an object. Also, for purposes of this disclosure, the term width means the dimension of an object from side to side. For the purposes of this disclosure, the term above generally means superjacent, substantially superjacent, or higher than another object although not directly overlying the object. Further, for purposes of this disclosure, the term mechanical communication generally refers to components being in direct physical contact with each other or being in indirect physical contact with each other where movement of one component affect the position of the other.

[0033] The use of any and all examples, or exemplary language (e.g., such as, or the like) provided herein, is intended merely to better illuminate the embodiments and does not pose a limitation on the scope of the embodiments or the claims. No language in the specification should be construed as indicating any unclaimed element as essential to the practice of the disclosed embodiments.

[0034] In the following description, it is understood that terms such as first, second, top, bottom, up, down, and the like, are words of convenience and are not to be construed as limiting terms unless specifically stated to the contrary.

[0035] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the present invention.
