Tennis ball retriever and storage cart |
摘要 |
A ball retrieving and storage cart generally comprises a wheeled carriage that rollingly supports a basket in a ball retrieving position. In an exemplary embodiment, the basket has a front end and a rear end and includes a bottom wall having two side members oriented front to rear and having a normal position spaced apart less than the ball diameter and defining a slotted aperture for entrance of a ball into the basket. In the ball retrieval position, at least one of the side members is a slanted member having a front end higher from the ground than a ball radius and a rear end lower to the ground than the ball radius. At least one of the side members is a deflectable member and is biased to the normal position but is sideways deflectable such that a ball on the ground entering the aperture sideways deflects the deflectable member sufficiently for the ball to pass into the basket. The wheels may define a rolling plane. The carriage includes a vertical frame member terminating in a push handle and the vertical frame member includes brackets for attaching a moveable basket at a serving position higher that is than the ball retrieving position.
