 The invention relates to a canopy structure for a play yard, and particularly a structure that has a base dock to engage with a canvas bracket and a claw to couple with the upper frame of a play yard to facilitate installation and removing, and provide improved shading through the canvas bracket which is adjustable angularly.
 Play yards mainly provide a safe playing space for infants or babies to protect them from exposure to danger when their parents are not around. When used outdoors, play yards that are not foldable have to be disassembled for transportation and assembled again for use. This is quite troublesome. Hence many parents prefer play yards that are constructed by movable joints and rods so that they can be easily extended and folded to make transporting by car easier. The foldable play yard disclosed in U.S. Pat. No. 4,811,437 is a typical example. However, when used outdoors, the play yard and the infant in the play yard are exposed to sunshine, which could be very irritating or even harmful to the infant. Hence play yards equipped with canopies were developed. For instance, U.S. Pat. No. 5,862,548 discloses a play yard system and canopy that has a canopy coupled to a play yard structure to provide shade. However, its canopy is not foldable. Assembly is troublesome and storage is difficult. Moreover, its fixed canopy structure forms a constant shading angle and cannot be adjusted to block the sunshine projecting in different angles at different times. The whole play yard has to be moved frequently to avoid direct sunshine. Its shading effectiveness and practicality are unsatisfactory.
 In view of the foregoing disadvantages, the primary object of the invention is to provide a canopy structure for an outdoor play yard that has a detachable canopy to protect the infant in the play yard from exposure to sunshine.
 Another object of the invention is to provide a pair of coupling base docks to connect the canopy structure so that the canopy structure may be selectively mounted onto the frame of the play yard to block sunshine when in use, and removed easily when not in use to facilitate folding and storage of the play yard.
 A further object of the invention is to provide a canvas bracket that includes a bracket seat, a pivotal hub and a plurality of supporting rods. The pivotal hub couples with the supporting rod and is pivotally engaged with the bracket seat such that the canvas bracket may be turned about the bracket seat to fold and unfold to facilitate storage without being removed from the base dock.
 Yet another object of the invention is to adjust the angle of the canvas bracket by turning the pivotal hub to provide desired shading according to change in the sunshine projecting angle to block unwanted sunshine effectively.
 The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
