Cart with flexible latch
View Patent ↗A cart has a container body and a lid rotatably affixed to the container body so as to be selectively rotated between an open position and a closed position. A latch has a first end adapted to be rotatably affixed to the lid. A second end is adapted to engage the container body. The first end is connected to the second end by an arched member, the arched member is capable of flexure when a force is applied at a concave surface of the arched member.
1. A cart comprising:
a body;
a lid rotatably affixed to the body and moveable between a first position and a second position; and
a plastic latch pivotally mounted on the lid for selectively locking the lid in a closed position, the latch having a first member adapted to be pivotally mounted to the lid; a second member adapted to selectively engage a projection on the housing; and an arched member connecting the first member to the second member, a plurality of support members extending along a concave surface of the arched member configured to provide some strength to the arch member, the arched member being deflected to lengthen the arched member to allow a catch on the second member to engage the projection when a force is applied to a convex surface of the arched member, wherein the first member pivots about an axis, and a slit is formed in the first member along said axis, off center of said first member, providing guiding means for correctly installing the plastic latch to the lid.
2. The cart of claim 1 , wherein the catch extends from the second member, the catch being disposed along the second member at a position such that when no force is applied to the convex surface the catch is disposed so as not to engage the projection when adjacent the body, and when a sufficient force is applied to the convex surface, the catch is disposed to engage the projection.
3. The cart of claim 1 , further comprising a pivot formed in the lid, the first member having a receiving portion for receiving the pivot therein.
4. The cart of claim 1 , wherein the catch is formed with a camming surface.
5. The crate of claim 1 , wherein said second member includes a handle, the handle formed with an arch, the arch extending in a direction opposite to a direction in which the arch member extends.
6. A plastic latch for selectively locking a lid to a cart body comprising a first member adapted to be pivotally mounted to a lid; a second member adapted to selectively engage a projection on a cart body; and an arched member connecting the first member to the second member, a plurality of support members extending along a concave surface of the arched member configured to provide some strength to the arched member, the arched member being deflected to allow a catch extending from the second member to engage the housing when a force is applied to a convex surface of the arched member, wherein the first member pivots about an axis, and a slit is formed in the first member along said axis off center of said first member providing guiding means for correctly installing the plastic latch.
7. The latch of claim 6 , wherein the catch being disposed along the second member at a position such that when no force is applied to the convex surface, the catch does not engage the cart body and when a sufficient force is applied to the convex surface, the catch engages the cart body.
8. The latch of claim 6 , further comprising a receiving portion for receiving a pivot therein.
9. The latch of claim 6 , wherein said catch includes a camming surface thereon.
10. The latch of claim 6 , wherein said second member includes a handle, the handle formed with an arch, the arch extending in a direction opposite to a direction in which the arch member extends.
