Cart connection assemblies and methods
View Patent ↗In certain embodiments, a connection assembly can engage a cart, such as a retail shopping cart, to facilitate pushing and/or pulling the cart or a number of carts that have been nested together. In some embodiments, the connection assembly includes an engagement member with a recess. In an open position of engagement member, the recess can be configured to receive a portion of a frame member of the cart. In a closed position of the engagement member, the portion of the frame member can be secured with the connection assembly, thereby providing a secure connection with the cart to facilitate movement of the cart to a desired location.
1. A cart connection assembly configured to releasably connect with a shopping cart, the connection assembly comprising:
a housing configured to couple with a cart retriever;
an engagement member pivotally connected with the housing and having a recess and a flange, the engagement member rotatable relative to the housing about an engagement member pivot axis between a first position and a second position with respect to the housing, wherein when in the first position the engagement member is configured to receive a leg portion of a shopping cart in the recess, and wherein when in the second position the leg portion is inhibited from being removed from the recess;
a biasing element configured to bias the engagement member toward the first position;
a latch configured to pivot relative to the housing about a latch pivot axis and configured to engage the flange of the engagement member when the engagement member is in the second position, thereby retaining the engagement member in the second position, the latch pivot axis being not parallel with the engagement member pivot axis; and
a release configured to disengage the latch and the flange, thereby allowing the engagement member to rotate from the second position to the first position.
2. The connection assembly of claim 1 , wherein the recess opens toward a front of the housing, the recess opening being generally unobstructed thereby facilitating access by the leg portion of the shopping cart.
3. The connection assembly of claim 1 , further comprising a plurality of engagement members connected with the housing and a corresponding plurality of latches configured to engage a respective one of the engagement members.
4. The connection assembly of claim 3 , wherein a lateral spacing between at least two of the plurality of engagement members is adjustable, thereby allowing for the connection assembly to connect with shopping carts of various widths.
5. The connection assembly of claim 1 , wherein when the leg portion is received in the recess and abuts the engagement member, the engagement member is encouraged to rotate from the first position toward the second position.
6. The connection assembly of claim 1 , wherein the latch further comprises a cam element configured to engage the engagement member when the engagement member rotates from the first position toward the second position.
7. The connection assembly of claim 1 , wherein the latch further comprises an opening configured to engage the flange of the engagement member.
8. The connection assembly of claim 1 , wherein the latch has a latched position and an unlatched position, the connection assembly further comprising a spring configured to bias the latch toward the latched position.
9. The connection assembly of claim 8 , wherein the release is configured to rotate the latch from the latched position to the unlatched position.
10. The connection assembly of claim 1 , wherein the release is manually actuated.
11. The connection assembly of claim 1 , wherein the leg portion of the shopping cart comprises a rear leg portion.
12. The connection assembly of claim 1 , wherein the housing is pivotably mounted to the cart retriever.
13. The connection assembly of claim 1 , further comprising the cart retriever, the housing being coupled with the cart retriever.
14. The connection assembly of claim 1 , further comprising a front-to-rear axis along which the shopping carts are collected, and wherein:
the housing further comprises a notch having a notch axis that is not perpendicular to the front-to-rear axis;
the recess comprises a recess axis extending along a longitudinal length of the recess;
the notch axis and the recess axis are not perpendicular when the engagement member is in the first position, thereby configuring the housing and the engagement member to allow the leg portion of the cart to be received in the notch and the recess; and
the notch axis and the recess axis are not parallel when the engagement member is in the second position, thereby configuring the housing and the engagement member to inhibit removal of the cart from the notch and the recess.
15. The connection assembly of claim 1 , wherein the biasing element biases the engagement member toward the first position such that the engagement member rotates from the second position toward the first position with sufficient force to eject the leg portion of the cart from the recess.
16. The connection assembly of claim 1 , wherein the latch pivot axis is perpendicular to the engagement member pivot axis.
17. The connection assembly of claim 14 , wherein the notch axis is parallel to the front-to-rear axis.
18. The connection assembly of claim 14 , wherein the notch axis and the recess axis are parallel when the engagement member is in the first position.
19. The connection assembly of claim 14 , wherein the notch axis and the recess axis are perpendicular when the engagement member is in the second position.
