Abstract

The disclosure generally relates to drywall carts and uses thereof. In aspects, a drywall cart is provided, which includes a cart frame, an overhanging safety bar, at least one pivot arm, and a lip guard, each configured to stabilize the drywall cart. In other aspects, a drywall cart safety kit is provided, which includes an overhanging safety bar, a first pivot arm and a second pivot arm, and a lip guard, configured to be attached to a drywall cart and to prevent the drywall cart to which it is attached from tipping or falling over. In further aspects, a method of using a drywall cart is provided, the method including the steps of raising an overhanging safety bar, loading drywall onto a base of the drywall cart, lowering the overhanging safety bar to secure the drywall, and transporting the drywall.

Claims (49)

1 . A drywall cart configured to transport one or more drywall sheets, the drywall cart comprising:

a cart frame;

an overhanging safety bar movably attached to the cart frame; and

a sheath, wherein the overhanging safety bar is configured to vertically slide within the sheath between a raised position and a lowered position;

wherein the overhanging safety bar is configured to be placed about the one or more drywall sheets to secure the one or more drywall sheets to the drywall cart during transport.

2 . The drywall cart of claim 1 , further comprising:

at least one pivot arm configured to stabilize the drywall cart; and

a lip guard configured to secure the one or more drywall sheets to the drywall cart during transport.

3 . The drywall cart of claim 1 , wherein drywall sheets may be loaded onto the drywall cart when the overhanging safety bar is in the raised position, and wherein the drywall sheets are secure on the drywall cart when the overhanging safety bar is in the lowered position.

4 . The drywall cart of claim 1 , further comprising at least one pivot arm configured to stabilize the drywall cart, wherein the at least one pivot arm is disposed in a perpendicular position relative to a base of the cart frame.

5 . The drywall cart of claim 4 , wherein the at least one pivot arm comprises a pivot assembly to enable motion of the at least one pivot arm towards the base of the cart frame, in either direction, upon application of force thereto.

6 . The drywall cart of claim 5 , wherein the at least one pivot arm is biased to revert to the perpendicular position absent a reaction force to retain the at least one pivot arm in an angled position.

7 . The drywall cart of claim 1 , further comprising a lip guard configured to secure the one or more drywall sheets to the drywall cart during transport, wherein the lip guard is configured to prevent the drywall sheets from falling from a base of the cart frame.

8 . The drywall cart of claim 1 , further comprising a lip guard configured to secure the one or more drywall sheets to the drywall cart during transport, wherein the lip guard is configured to alternate between a stored position and a deployed position via at least one latch arm.

9 . The drywall cart of claim 1 , further comprising a plurality of wheels, each wheel of the plurality of wheels coupled to the cart frame.

10 . The drywall cart of claim 9 , further comprising a pair of pivot arms configured to stabilize the drywall cart, each pivot arm of the pair of pivot arms having a wheel assembly separate from the plurality of wheels and coupled to the cart frame via an arm portion.

11 . A cart configured to transport one or more drywall sheets, the cart comprising:

an overhanging safety bar;

a sheath, wherein the overhanging safety bar is configured to vertically slide within the sheath between a raised position and a lowered position;

a first pivot arm and a second pivot arm; and

a lip guard;

wherein each of the overhanging safety bar, the first pivot arm and the second pivot arm, and the lip guard are configured to prevent the cart and/or the one or more drywall sheets from tipping or falling over.

12 . The cart of claim 11 , wherein the first pivot arm and the second pivot arm are disposed on opposite sides of a base of the cart.

13 . The cart of claim 12 , wherein each of the first pivot arm and the second pivot arm are disposed perpendicular to the base of the cart.

14 . The cart of claim 11 , wherein each of the first pivot arm and the second pivot arm comprises:

a wheel assembly;

a pivot assembly; and

an arm portion extending between the wheel assembly and the pivot assembly;

wherein the arm assembly couples the wheel assembly to the pivot assembly to facilitate movement of the wheel assembly relative to a base of the cart.

15 . The cart of claim 14 , wherein the pivot assembly comprises a pivot pin and a spring attached thereto.

16 . A method of using a drywall cart, the method comprising:

raising an overhanging safety bar;

loading drywall onto a base of the drywall cart;

lowering the overhanging safety bar to secure the drywall;

moving a lip guard from a stowed position into a deployed position to further secure the drywall; and

transporting the drywall.

17 . The method of claim 16 , wherein the drywall cart comprises a plurality of pivot arms disposed perpendicular to the base of the drywall cart.

18 . The method of claim 17 , wherein the plurality of pivot arms are configured to flex during transportation of the drywall cart upon contact with a passing surface.

19 . A drywall cart configured to transport one or more drywall sheets, the drywall cart comprising:

a cart frame;

an overhanging safety bar movably attached to the cart frame to secure the one or more drywall sheets to the drywall cart during transport; and

at least one pivot arm configured to stabilize the drywall cart, wherein the at least one pivot arm is disposed in a perpendicular position relative to a base of the cart frame,

wherein the at least one pivot arm comprises a pivot assembly to enable motion of the at least one pivot arm towards the base of the cart frame, in either direction, upon application of force thereto, and

wherein the at least one pivot arm is biased to revert to the perpendicular position absent a reaction force to retain the at least one pivot arm in an angled position.

20 . A drywall cart configured to transport one or more drywall sheets, the drywall cart comprising:

a cart frame;

an overhanging safety bar movably attached to the cart frame to secure the one or more drywall sheets to the drywall cart during transport; and

a lip guard configured to secure the one or more drywall sheets to the drywall cart during transport,

wherein the lip guard is configured to alternate between a stored position and a deployed position.
