Abstract
A portable container has a floor support assembly with parallel side support rails extending from the front to the rear of the assembly and an intermediate support rail between and parallel to the side support rails. Floor support members are secured to and extend transversely across the rails. A floor is secured to the floor support members. The support rails have a height sufficient to enable the tines of a lifting device to pass under the floor support members for lifting the container. A lower stabilizing member is secured to the bottom of one or more of the deck support members and defines a downwardly facing landing pad surface. The landing pad surface has a width that is less than the distance between the tines of the lifting device and a length that is greater than the distance between the tines of the lifting device.
Description
- The present invention relates generally to portable storage containers. More particularly, it relates to a portable storage container with a pallet floor support assembly that can be accessed by a lifting device from either end or side. The container can be lifted from the side with a lifting device having relatively short tines, such as a pallet jack.
- Storage containers that can be lifted by a forklift or similar lifting device are known. In addition, pallets that support and secure goods while they are being lifted by a forklift, pallet jack, or other lifting device are known. Such containers and pallets, however, have a number of drawbacks. A traditional or standard pallet can only be lifted by a forklift engaging the pallet from either end—but not the side. Such a pallet has four stringers, or rails, which are used to add stability to the pallet and to guide the lifting-device tines into place only from one end or the other. It is often desirable, however, to lift a pallet with forklift from one of its sides rather than just from one of its ends.
- In addition, traditional storage containers and larger pallets cannot be conveniently lifted using standard warehouse lifting devices, such as a standard pallet jack or forklift. These containers and larger pallets typically have dimensions that exceed the fork tine length limitations of standard lifting devices, which have relatively short tines. Such storage containers and pallets therefore require specialized equipment, or frequent use of fork extensions or readjustment of the distance between the fork tines.
- It is an object of the present invention, therefore, to provide an improved portable storage container and a pallet base that can be lifted with a lifting device, such as a forklift, from the front, back or either side of the container.
- Another object of the present invention is to provide such a portable storage container and pallet base that can be lifted using standard warehouse lifting devices, such as a pallet jack.
- Yet another object of the invention is to provide such a portable storage container and pallet base that can be lifted from the front, back or either side without having to adjust the distance between the tines of the lifting device.
- Still another object of the present invention is to provide a pallet base that requires fewer rails or stringers than the traditional four stringers.
- Additional objects and advantages of the invention will be set forth in the description that follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations pointed out in the appended claims.
- To achieve the foregoing objects, and in accordance with the purposes of the invention as embodied and broadly described in this document, there is provided a portable container with a floor support assembly that has two generally parallel side support rails extending from the front to the rear of the floor support assembly. An intermediate support rail is disposed between and generally parallel to the side support rails. Floor support members are secured to and extend transversely across the rails. A floor is secured to at least one of the floor support members. The support rails have a height sufficient to enable the tines of a lifting device to pass under the floor support members for lifting the container. One or more relatively short lower stabilizing members are secured to the bottom of one or more of the deck support members and define a generally planar downwardly facing landing pad surface. The landing pad surface has a width that is less than the distance between the tines of the lifting device and a length that is greater than the distance between the tines of the lifting device.
- In this configuration, the container can be lifted from the front, back or either side of the container using standard warehouse lifting devices, such as a forklift or pallet jack. The stabilizing members provide a support surface or landing pad that can rest on the tines of a forklift that engages the container from the side. With these stabilizing members, the improved pallet requires only three lengthwise stringers, rather than the traditional four stringers. The dimensions and placement of the stabilizing members also allow for lifting of the container from the front, back or either side without having to adjust the distance between the tines of the lifting device.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate the presently preferred embodiments of the invention and, together with the general description given above and the detailed description of the preferred embodiments given below, serve to explain the principles of the invention.

Also as used in this document, the term “assembly” can include a single member or an assembly of components.
- Referring to
FIG. 1 , a portable storage container, generally designated 10, is shown. Thestorage container 10 can be lifted by a lifting device that engages the container from thesides front end 22 orrear end 23. Thecontainer 10 includesopposing side walls 12, a back wall 14 (not shown), atop 16, afloor 18 supported by afloor support assembly 20 and a hingeddoor 24 for providing access for loading and unloading thestorage container 10. In the embodiment shown inFIG. 1 , thewalls 12, 14,top 16,floor 18 anddoor 24 are made of sheet material, such as sheets of plywood, and thestorage container 10 includes aprotective cover 25, such as a vinyl cover, for protection against the elements. In one preferred embodiment, thestorage container 10 is about 8 feet long, 5 feet wide and 7 feet high. - Referring to
FIGS. 2-5 , thefloor support assembly 20 is in the form of a pallet, including two generally parallel side rails orstringers intermediate rail 28 that is generally parallel to and disposed between theside rails 26. Each of therails floor support assembly 20. Most typically, thefloor support assembly 20 will be elongated in the direction of therails rails rails Floor support members 30 are secured to an upwardly facing surface of theside rails 26 and extend transversely across therails container floor 18 is secured to the tops of thefloor support members 30 to provide a generally planar, upwardly facing floor surface. Each of theside rails 26 has achannel 27 along its length for receiving a lower edge of one of theside walls 12. - Still referring to
FIGS. 2-5 , each of theside rail assemblies 26 includes acorner support block 32 at each of its ends and aside support block 33 midway between its ends. Similarly, theintermediate rail assembly 28 includes anend support block 34 at each of its ends and acenter support block 35 midway between its ends. The support blocks 32, 33, 34, 35 support therails tines 50 of a lifting device, such as a forklift, to pass under therails container 10. Thecorner support block 32 and theend support block 34 define tine-receivingopenings 40 in the front and rear of thefloor support assembly 20 to allow the lifting device to engage the container from the front or the rear. Thecorner support blocks 32 andside support blocks 33 define tine-receivingopenings 42 in the sides of thefloor support assembly 20 to allow the lifting device to engage the container from eitherside container 10 from the front 22, rear 23 or either of thesides tine receiving openings container 10. - As can be seen in
FIGS. 2 and 5 , preferably the corner support blocks 32 and the side support blocks 33 have chamfered orbeveled feet center support block 35 have beveledfeet feet floor 18 for added structural strength. Thebeveled feet feet tines 50. If the tines of the lift device are misaligned as they are inserted under thefloor support assembly 20 such that the ends of the tines strike thefeet - Referring to
FIGS. 4-7 , two relatively short lower stabilizingmembers 36 are secured to the bottom of a plurality of thefloor support members 30. The lower stabilizingmembers 36 are in the form of boards mounted generally parallel to theintermediate rail 28 on either side of thecenter support block 35 and are long enough to traverse three of thefloor support members 30. With the stabilizingmembers 36, thefloor support assembly 20 requires only three lengthwise rails, rather than the four rails of a traditional pallet. Preferably, the lower stabilizingmembers 36 have a thickness that is the same as that of theintermediate rail 28. The lower stabilizingmembers 36 and theintermediate rail 28 define a generally planar downwardly facinglanding pad surface 38. Thelanding pad surface 38 has a width W that is less than the distance between thetines 50 and a length L that is greater than the distance between thetines 50. In one preferred embodiment, wherein the width of the floor support assembly is 20 is about 5 feet, each of the lower stabilizingmembers 36 has a length of about 34 inches and a width of about 5.5 inches. The landing pad surface width W is about 17.5 inches and the landing pad surface length L is about 34 inches. - As shown in
FIG. 7 , in this configuration, thelanding pad surface 38 provides a support surface that can rest on thelifting device tines 50 when the lifting device engages thecontainer 10 from either side. While, as shown inFIG. 6 , this configuration also allows for the lifting device tines 50 (shown with tine extensions 51) to be inserted underneath thefloor support members 30 from theends container 10 on either side of thelanding pad surface 38 and without interference from thelanding pad surface 38. - Also preferably, the stabilizing
members 36 have tapered ends 37. In this configuration, if the tines of the lifting device are misaligned as they are inserted under thefloor support assembly 20 from one of the container ends 22, 23 so that a tine strikes one of the stabilizing member ends 37, the tapered shape will tend to cause thestabilizer member 36 to glance off the tine rather than being caught on it. - In one preferred embodiment of the
container 10, therails floor support members 30, the support blocks 32, 33, 34, 35 and the lower stabilizingmembers 36 are made of wood and thefeet - Upon reading this disclosure, it will be understood that the portable storage container of the present invention provides a number of advantages over previous designs. A container according to the invention can be lifted with a lifting device, such as a forklift, from the front, back or either side of the container. The container can be lifted using standard warehouse lifting devices, such as a pallet jack. The relatively short stabilizing members oriented lengthwise underneath the central area of the pallet platform provide a support surface or landing pad that can rest on the tines of a forklift used to lift the pallet from the side. With these stabilizing members, the improved pallet requires only three lengthwise stringers, rather than the traditional four stringers. The dimensions and placement of the stabilizing members also allow for lifting the container from the front, back or either side without having to adjust the distance between the tines of the lifting device.
- Having read this disclosure, it will also be understood by those having skill in the art that modifications may be made to the invention. Therefore, the invention in its broader aspects is not limited to the specific details, representative devices, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the general inventive concept.
