Description
-;3 ;I;his invention relates to a multi-purpose pallek which, in o~e of the aspects of the invention, can ~e used ac: a flat pallet for the handling ol :joods, in another aspect as a palle~ container, or which in a still ~urther aspect 5. can be extended to be used as a flat pallet of larger dimension.
In industry one of the difficulties encountered in pallets is their inflexibility, in that they cannot be used for general purposes. There is a well recognized need to 10. have containers which can also be used as pallets, but attempts which have been made to provide such dual purpose products have heretofore met with only limited success, and the main object of this invention is to provide a pallet having demountable side walls which will make a satisfactory container, 15. that is, a container which will have relatively rigid sides and which will withstand normal wear and tear without losing its demountable facility. :
~riefly in this invention there is provided, in a pallet 20. having upright tubular spaces between a base frame and a load frame, a pair of side frames inserted into the upper ends of the tubular spacers and a pair of end rails which engage the side frames and hold them in position, arranged so that the pallet may be used as a flat pallet or as a contdiner.
25. Specifically, in one aspect of the invention a pallet has a base frame, a load frame, a pair of side frames, and a pairof end rails, a plurality of spacers joining the base frame to the load frame, said spacers comprising tubular sec~ion corner .., ' .,~
-members extending vertically and constituting sockets, each said side frame having posts the depending ends of which are releasably insertable in respective said sockets to be supported thereby to be upstanding therefrom, each end rail having retaining means releasably interengageable with the side frames and operable to retain the upper ends of the side frames in spaced relationship with each other and a pair of outrigger frames releasably engageable with the load frame and arranged to project outwardly from the ends thereof.
Another problem encountered with pallets is that different products require different platform sizes, and a Eurther object of this invention is to provide improvements whereby a pallet can be extended to become of larger dimension.
In another aspect of the invention each outrigger may have projecting beams which engage a load frame bearer, and a bearer which engages the load frame. This then provides a very simple and ef*ective mean~ for e~tending the area of a pallet.
An embodiment of the invention i~ described hereunder in some detail with reference to and as illustrated in the accompan~ing drawings, in which:
Figure 1 is an "exploded" view of a pallet which em-bodies the first aspect of the invention, including a base frame, a load frame, a pair of side frames and a pair of end rails;
Figure 2 is an end elevation taken in the direction of arrow "2" on Figure 1, Figure 3 is a side elevation taken in the direction of arrow "3" on Figure 1, Figure 4 is a fragmentary plan illustrating an out-rigger on the load frame, and Fig. 5 is a corresponding fragmentary side elevational section taken on line 55 Of Fig. ~l.
In this embo(liment a pallet 10 is forme~ to have a 5. base frame 11 (which is normally the ground-engaging frame) and a load frame 12 (which normally supports a load), there being tubular spacers 13 between the frames 11 and 12.
The base frame 11 comprises three parallel bars 15 which are flat members arranyed to lie on the ground and 10. thereby enable a jacking truck to ride over them to get beneath the pallet in one direction only, and end rails 16 of tubular sectioi~ positioned adjacent the ground so as to allow entry of the forks of a fork lift truck (even though they will not allow entry of a jacking truck).
15. The load frame 12 comprises side rails 18 formed from rectangular section tubing and end rails 19 formed from square section tubing, there being intermediate bearers 20 between the end rails also of square tubing and of si~ilar section to the end rails. The spacers 13 which join the 20. load frame and base frame are also of rectangu~ar section tubing but are relatively short in length. The spacers 13 at the corners of the end rails project outwardly to provide support shelves 22 at each ~:orner of the pallet as seen best in Fig. 1. Each corner is also provided with an 25. upstanding square tubular socket 23 which functions as a socket for receiving the lower end of a frame post of a side frame.
Each side frame 26 is a substantiall~ rectangular frame having two posts at its ends which are insertable within respe¢~ve sockets 23 at the corners of the pallet. The upper end of each post 27 forms a tub~,lar socket, and its lower end is chamfered at 2~. Each side frame 26 has a upper rail 30 and a lower rail 31 both of which are of rect-5. angular section tubing, and circular section bracing struts 32 join the rails 30 and 31. Each rail 30 has a pair of upwardly and inwardly sloping locating lugs 33 thereon, which abut against and thereby locate side bars 15 of another pallet when stacked.
10. ~ach end rail 35 is provided with a pair of depending spigots 3~ each of which enters a socket constituted by the upper end of a respective side frame post 27. This prevents inward displacement of the upper ends of both the side frames and end frames. The lower ends of the side 15. frames are prevented from displacement in any direction by virtue of the spigot and socket c:onnections. The construction described above is found to give a surprisingly rigid structure when the end rails and side frames are positioned on the pallet base and load frames to form therewith a pallet container.
20. Furthermore the bearers can ~upport a planar sheet of material (for example cardboard).
The invention however extends in one of its aspects beyond a pallet container as described above and in another aspect of the invention illustrated in Figs. 4 and 5, there ~ 25. are provided outriggers 41 which are rectangular frames having - projecting beams 42 extending inwardly toward one another from opposite ends of base frame 11. The projecting beams 42 lie beneath the end rails 19 and bearers ~0, and carry on them ~7~3 tubular section retainers 43, the beams 42 of each outrigger also having thereon a pair of bearers 44, the arrangement being such that a bearer o each outrigger is supported by the support shelves 22 on the ends of the pallet base frame, S. and a bearer 44 abuts the outer side surface of respective end rails 19 of the load frame of the pallet base as shown in FiyO 5. The tubular section retainers 43 abut the inner fac0s of the square end rails 19 of the pallet base to prevent outward displacement of the outriggers. End-wise 10. displacement is prevented by abutment of the ends of the bearers 44 against the rectangular tubular sockets 23 of the pall~t base.
The invention will be seen to be very simple, but notwithstanding its simplicity the invention results in an 15. effective multi-purpose pallet which can be used as a four-way pallet for fork lift trucks, a two-way pallet for jacking trucks, a container, or an extensible pallet.
In industry one of the difficulties encountered in pallets is their inflexibility, in that they cannot be used for general purposes. There is a well recognized need to 10. have containers which can also be used as pallets, but attempts which have been made to provide such dual purpose products have heretofore met with only limited success, and the main object of this invention is to provide a pallet having demountable side walls which will make a satisfactory container, 15. that is, a container which will have relatively rigid sides and which will withstand normal wear and tear without losing its demountable facility. :
~riefly in this invention there is provided, in a pallet 20. having upright tubular spaces between a base frame and a load frame, a pair of side frames inserted into the upper ends of the tubular spacers and a pair of end rails which engage the side frames and hold them in position, arranged so that the pallet may be used as a flat pallet or as a contdiner.
25. Specifically, in one aspect of the invention a pallet has a base frame, a load frame, a pair of side frames, and a pairof end rails, a plurality of spacers joining the base frame to the load frame, said spacers comprising tubular sec~ion corner .., ' .,~
-members extending vertically and constituting sockets, each said side frame having posts the depending ends of which are releasably insertable in respective said sockets to be supported thereby to be upstanding therefrom, each end rail having retaining means releasably interengageable with the side frames and operable to retain the upper ends of the side frames in spaced relationship with each other and a pair of outrigger frames releasably engageable with the load frame and arranged to project outwardly from the ends thereof.
Another problem encountered with pallets is that different products require different platform sizes, and a Eurther object of this invention is to provide improvements whereby a pallet can be extended to become of larger dimension.
In another aspect of the invention each outrigger may have projecting beams which engage a load frame bearer, and a bearer which engages the load frame. This then provides a very simple and ef*ective mean~ for e~tending the area of a pallet.
An embodiment of the invention i~ described hereunder in some detail with reference to and as illustrated in the accompan~ing drawings, in which:
Figure 1 is an "exploded" view of a pallet which em-bodies the first aspect of the invention, including a base frame, a load frame, a pair of side frames and a pair of end rails;
Figure 2 is an end elevation taken in the direction of arrow "2" on Figure 1, Figure 3 is a side elevation taken in the direction of arrow "3" on Figure 1, Figure 4 is a fragmentary plan illustrating an out-rigger on the load frame, and Fig. 5 is a corresponding fragmentary side elevational section taken on line 55 Of Fig. ~l.
In this embo(liment a pallet 10 is forme~ to have a 5. base frame 11 (which is normally the ground-engaging frame) and a load frame 12 (which normally supports a load), there being tubular spacers 13 between the frames 11 and 12.
The base frame 11 comprises three parallel bars 15 which are flat members arranyed to lie on the ground and 10. thereby enable a jacking truck to ride over them to get beneath the pallet in one direction only, and end rails 16 of tubular sectioi~ positioned adjacent the ground so as to allow entry of the forks of a fork lift truck (even though they will not allow entry of a jacking truck).
15. The load frame 12 comprises side rails 18 formed from rectangular section tubing and end rails 19 formed from square section tubing, there being intermediate bearers 20 between the end rails also of square tubing and of si~ilar section to the end rails. The spacers 13 which join the 20. load frame and base frame are also of rectangu~ar section tubing but are relatively short in length. The spacers 13 at the corners of the end rails project outwardly to provide support shelves 22 at each ~:orner of the pallet as seen best in Fig. 1. Each corner is also provided with an 25. upstanding square tubular socket 23 which functions as a socket for receiving the lower end of a frame post of a side frame.
Each side frame 26 is a substantiall~ rectangular frame having two posts at its ends which are insertable within respe¢~ve sockets 23 at the corners of the pallet. The upper end of each post 27 forms a tub~,lar socket, and its lower end is chamfered at 2~. Each side frame 26 has a upper rail 30 and a lower rail 31 both of which are of rect-5. angular section tubing, and circular section bracing struts 32 join the rails 30 and 31. Each rail 30 has a pair of upwardly and inwardly sloping locating lugs 33 thereon, which abut against and thereby locate side bars 15 of another pallet when stacked.
10. ~ach end rail 35 is provided with a pair of depending spigots 3~ each of which enters a socket constituted by the upper end of a respective side frame post 27. This prevents inward displacement of the upper ends of both the side frames and end frames. The lower ends of the side 15. frames are prevented from displacement in any direction by virtue of the spigot and socket c:onnections. The construction described above is found to give a surprisingly rigid structure when the end rails and side frames are positioned on the pallet base and load frames to form therewith a pallet container.
20. Furthermore the bearers can ~upport a planar sheet of material (for example cardboard).
The invention however extends in one of its aspects beyond a pallet container as described above and in another aspect of the invention illustrated in Figs. 4 and 5, there ~ 25. are provided outriggers 41 which are rectangular frames having - projecting beams 42 extending inwardly toward one another from opposite ends of base frame 11. The projecting beams 42 lie beneath the end rails 19 and bearers ~0, and carry on them ~7~3 tubular section retainers 43, the beams 42 of each outrigger also having thereon a pair of bearers 44, the arrangement being such that a bearer o each outrigger is supported by the support shelves 22 on the ends of the pallet base frame, S. and a bearer 44 abuts the outer side surface of respective end rails 19 of the load frame of the pallet base as shown in FiyO 5. The tubular section retainers 43 abut the inner fac0s of the square end rails 19 of the pallet base to prevent outward displacement of the outriggers. End-wise 10. displacement is prevented by abutment of the ends of the bearers 44 against the rectangular tubular sockets 23 of the pall~t base.
The invention will be seen to be very simple, but notwithstanding its simplicity the invention results in an 15. effective multi-purpose pallet which can be used as a four-way pallet for fork lift trucks, a two-way pallet for jacking trucks, a container, or an extensible pallet.
