Dolly device for loading containers
View Patent ↗A dolly device for loading and unloading a container which comprises a control frame that pivots among a plurality of operational positions such that the control frame facilitates the loading or unloading of the container and supports the container while being transported from location to location.
1. A dolly device for loading and unloading a container, comprising:
a. a base having a lower portion supported by a plurality of roller devices;
b. a support surface operably mounted relative to the base and having a plurality of friction reducing members configured to reduce the amount of friction between the support surface and a container moving on the support surface;
c. a control frame mounted above the base and the support surface for pivoting between a plurality of operational positions for selectively limiting the movement of a container supported on the support surface; and
d. a locking mechanism having a plurality of locking positions configured to selectively hold the control frame in a plurality of stop positions.
2. A dolly device according to claim 1 , wherein the control frame is mounted by support members.
3. A dolly device according to claim 2 , wherein the support members extend between the base and the control frame providing support for pivotal movement of the control frame relative to the base.
4. A dolly device according to claim 1 , wherein the support surface is movably supported relative to the base.
5. A dolly device according to claim 4 , wherein the support surface is mounted relative to the base such that the support surface can be adjusted along a substantially horizontal axis relative to the base.
6. A dolly device according to claim 4 , wherein the support surface is mounted relative to the base such that the support surface can be adjusted along both the substantially widthwise and substantially lengthwise axes relative to the base.
7. A dolly device according to claim 4 , further comprising an adjustable assembly configured to selectively locate the support surface at one of a plurality of heights relative to the base.
8. A dolly device according to claim 1 , wherein the friction reducing members comprise rotatable members.
9. A dolly device according to claim 8 , wherein the rotatable members comprise cylindrical rollers.
10. A dolly device according to claim 1 , wherein the control frame comprises at least one leverage handle.
11. A dolly device according to claim 10 , wherein the control frame comprises at least one unloading extension configured with the leverage handle to initiate removal of the container from the dolly device.
12. A dolly device according to claim 1 , wherein the locking mechanism comprises at least three locking positions, each corresponding to an operational position of the control frame.
13. A dolly device for loading and unloading a container, comprising:
a. a base having a lower portion supported by a plurality of roller devices;
b. a support surface operably mounted relative to the base and having a plurality of friction reducing members configured to reduce the amount of friction between the support surface and a container moving on the support surface;
c. a control frame mounted above the base and the support surface for pivoting between a plurality of operational positions for selectively limiting the movement of a container supported on the support surface; and
d. a multi-positional gate lock attached to the control frame and defining a plurality of unloading and loading positions for the control frame,
e. support members extending between the base and the control frame providing support for pivotal movement of the control frame relative to the base.
14. A dolly device according to claim 13 , further comprising an adjustable assembly configured to selectively locate the support surface at one of a plurality of heights relative to the base.
15. A dolly device according to claim 13 , wherein the support surface is mounted relative to the base such that it can be adjusted along both the substantially widthwise and substantially lengthwise axes relative to the support surface.
16. A dolly device according to claim 13 , wherein the control frame comprises at least one leverage handle.
17. A dolly device according to claim 16 , wherein the control frame comprises at least one unloading extension configured with the leverage handle to initiate removal of the container from the dolly device.
