JOINT STRUCTURE BETWEEN A BIKE REAR RACK AND A SHOPPING CART

WIPO Patent Application WO/2011/129532

A2

The present invention relates to a joint structure between a bike rear rack and a shopping cart. The rear rack comprises at least one wire arranged at right angles to the longitudinal direction of the bike; and the shopping cart comprises a tray having wheels attached to both sides thereof, and a handle coupled to the tray. For the handle, an eye bolt which has a ring at the tip is mounted on the top of the handle. The wire is coupled to a joint device detachable from the eye bolt, with the joint device comprising: two parallel fixing boards, each having an opening formed in one side; a pair of arc-shaped locking pieces that are hinged between the fixing boards by means of a hinge pin, so as to open and close the mouth portion of the opening; and a support plate for receiving the fixing boards and the locking piece therein, while being joined to the wire. The present invention with the configuration described above is advantageous in that the bike and the shopping cart can be easily attached to and detached from each other, whenever necessary. In addition, the locking pin pair creates a more stable joint state to the eye bolt, and the use of a locking pin prevents the separation of the joint device and the eye bolt due to an external shock.
