Convertible pallet with selectively actuated rolling feature
A convertible pallet assembly, and associated method of making the convertible pallet, includes a first, planar pallet surface, and a second, planar support surface spaced therefrom. First and second sidewalls extend in parallel relation between the pallet surface and the support surface from adjacent opposite sides thereof. The sidewalls include first and second wheels with respective rotational axes that extend perpendicular to the sidewalls. An actuation mechanism is associated with each sidewall. The actuation mechanism has (i) a first position that allows the first and second wheels on one side to move upwardly and downwardly relative to the sidewall in a non-load carrying condition, and (ii) a second position such that the first and second wheels on the one side project outwardly from the support surface in a load carrying condition whereby the assembly can be rolled on the wheels as a cart.
1. A convertible pallet assembly comprising:
a first, planar pallet surface;
a second, planar support surface;
first and second sidewalls extending between the pallet surface and the support surface from adjacent opposite sides thereof, the sidewalls disposed in parallel relation to one another and each sidewall includes at least first and second wheels with respective rotational axes that extend perpendicular to the sidewalls; and
an actuation mechanism operatively associated with each sidewall, the actuation mechanism of each sidewall having (i) a first position that allows the first and second wheels on a side to move upwardly and downwardly relative to the sidewall in a non-load carrying condition, and (ii) a second position such that the first and second wheels on the one side project outwardly from the support surface in a load carrying condition whereby the assembly can be rolled on the wheels as a cart, each actuation mechanism including an interconnecting member joining the first and second wheels on the side, and wherein the interconnecting member is configured to slide fore and aft relative to the respective sidewall.
2. The pallet assembly of claim 1 wherein the first and second wheels of the first sidewall move together upwardly and downwardly relative thereto.
3. The pallet assembly of claim 2 wherein the first and second wheels of the second sidewall move together upwardly and downwardly relative thereto.
4. The pallet assembly claim 2 wherein the first and second wheels of the second sidewall move together upwardly and downwardly relative thereto, and move upwardly and downwardly independent of the first and second wheels of the first sidewall.
5. The pallet assembly of claim 1 wherein the pallet surface and the support surface are spaced apart by a predetermined dimension adapted to receive associated arms of an associated pallet jack or associated forklift.
6. The pallet assembly of claim 1 wherein the interconnecting member is configured to slide upwardly and downwardly relative to the support surface.
7. The pallet assembly of claim 6 wherein the interconnecting member includes at least one raised surface extending outwardly therefrom that selectively engages a projecting surface operatively associated with the pallet surface, the raised surface and the projecting surface spaced from one another in the first position of the actuating mechanism, and abutting one another in the second position of the actuating mechanism.
8. The pallet assembly of claim 7 further comprising a recess that receives the raised surface in the first position of the actuating mechanism.
9. The pallet assembly of claim 8 wherein each actuating mechanism includes a cam and a follower that is interposed between the pallet surface and the first and second wheels.
10. The pallet assembly of claim 9 wherein the cam is provided on one of the pallet surface and the sidewall, and the follower is provided on the interconnecting member.
11. The pallet assembly of claim 10 wherein the cam is a face cam having a generally L-shaped slot formed by first and second portions in which the first portion extends between the pallet surface and the support surface, and the second portion extends generally parallel to the support surface.
12. The pallet assembly of claim 11 wherein the cam surface further includes first and second detents at distal ends of the first portion and second portion, respectively.
13. The pallet assembly of claim 1 wherein each sidewall includes first and second wall portions forming a cavity therebetween that receives the first and second wheels on a respective side.
14. A method of making a convertible pallet assembly comprising:
providing a first, planar pallet surface;
providing a second, planar support surface;
joining the pallet surface to the support surface with first and second sidewalls extending therebetween, wherein each sidewall includes at least first and second wheels;
providing an interconnection member on each sidewall that joins the first and second wheels thereof, and configuring the interconnecting member to slide fore and aft relative to the respective sidewall; and
moving the first and second wheels between (i) a first position that allows the first and second wheels on one side to move upwardly and downwardly relative to the sidewall in a non-load carrying condition, and (ii) a second position such that the first and second wheels on the one side project outwardly from the support surface in a load carrying condition whereby the assembly can be rolled on the wheels as a cart.
