Abstract
A canopy support is movable relative to a juvenile seat to raise and lower a canopy with respect to the seat. The canopy support includes a hub mount on each side of the seat, an arched canopy frame, and a hub mount ring for connecting each end of the arched canopy frame to one of the hubs. Each hub mount ring is configured to interact with its companion hub to retain the arch canopy frame in a selected position relative to the seat.
Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates to a canopy, and particularly, to a canopy used with a juvenile seat. More particularly, the present invention relates to a canopy and canopy frame used with an infant or juvenile seat.




Canopies are used with infant or juvenile seats to protect a child from inclement weather conditions, such as hot sun, wind, rain, and snow. Canopies for juvenile seats frequently are positioned over the juvenile seat to cover at least a child's head and upper torso from such weather conditions. Since weather can change frequently and unexpectedly, it is desirable to have a canopy assembly having some components already coupled to the juvenile seat, the remaining components attaching rapidly to provide a protective cover for the child.




According to the present disclosure, a juvenile seat unit includes a seat and a canopy support movable relative to the seat to raise and lower a canopy with respect to the seat. The canopy support includes a hub coupled to each side of the seat and a hub mount ring anchored to each of the hubs to rotate about a hub axis associated therewith.




An arched canopy frame is included in the juvenile seat unit and is coupled to the hub mount rings to rotate therewith. An interface between at least one of the hubs and its companion hub mount ring provides means for releasably retaining the arched canopy frame in a fixed position relative to the seat selected by the user so that a canopy carried on the canopy support can be retained in a selected position relative to the seat.




Each hub mount ring is formed to include an inner edge defining a circular aperture receiving one of the hubs therein. Each hub mount ring is able to rotate about its companion hub as the arched canopy frame is moved by a user to a selected position.




In preferred embodiments, the interface between each hub and its companion hub mount ring is established by peripherally spaced-apart, radially outwardly extending teeth on the hub and radially inwardly extending teeth on the hub mount ring. The hub mount ring teeth mate with the hub teeth to retain the arched canopy frame in a fixed position relative to the seat at the option of the user.




Each hub mount rim includes first and second C-shaped sections arranged to extend around one of the hubs provided on the side of the seat. The first C-shaped section of each hub mount ring is coupled to the arched canopy frame. Two extensible accordion links are included in each hub mount ring and arranged to interconnect the first and second C-shaped sections so that those sections can move relative to one another.




The canopy support preferably includes two arched canopy frames that cooperate to support the canopy over the seat when the canopy is raised and alongside the seat when the canopy is lowered. Thus, two hub mount rings are anchored to each of the hubs. A first of the arched canopy frames is coupled to a first pair of the hub mount rings and a second of the arched canopy frames is coupled to a second pair of the hub mount rings so that each arched canopy frame can be rotated about an axis extending through the hubs (relative to the seat and to the other arched canopy frame) to raise and lower the canopy.




Features of the invention will become apparent to those skilled in the art upon consideration of the following detailed description of preferred embodiments exemplifying the best mode of carrying out the invention as presently perceived.

includes a cylindrical wall


70


having a diameter sized to fit into aperture


60


formed in each hub mount ring


28


,


30


,


32


,


34


so that each of rings


28


,


30


,


32


,


34


can be mounted on one of canopy support hubs


20


,


24


to rotate about the hub axis


25


. Each hub


20


,


24


further includes a plurality of peripherally spaced-apart, radially outwardly extending hub teeth


72


on cylindrical wall


70


as shown, for example, in

FIGS. 4-6

.




As suggested, for example, in

FIG. 6

, the radially inwardly extending teeth


65


in the toothed peripheral segment


64


of each hub mount ring


28


,


30


,


32


,


34


engage the hub teeth


72


on one of hubs


20


,


24


to retain the hub mount rings


28


,


30


,


32


,


34


in selected fixed positions relative to hubs


20


,


24


. This causes the arched canopy frames


36


,


38


, which frames


36


,


38


are coupled to the hub mount rings


28


,


30


,


32


,


34


, to be retained in selected fixed positions relative to seat


12


so as to establish a position of the canopy


14


carried on the arched canopy frames


36


,


38


relative to the seat.




By rotating the hub mount rings


28


,


30


,


32


,


34


about the hub axis


25


relative to the hubs


20


,


24


, the radially inwardly extending teeth


65


in the toothed peripheral segment


64


of each hub mount ring


28


,


30


,


32


,


34


ratchet or otherwise move relative to hub teeth


72


on hubs


20


,


24


to enable a user to move the arched canopy frames


36


,


38


about hub axis


25


and thereby raise and lower canopy


14


with respect to seat


12


. Such ratcheting movement is facilitated by extension and contraction of the extensible accordion links


54


,


56


provided to couple the C-shaped sections


50


,


52


for relative movement to one another in each hub mount ring


28


,


30


,


32


,


34


.




First extensible link


54


is defined by a first V-shaped slot


80


positioned to interrupt smooth surfaces on edges


62


,


66


of C-shaped sections


50


,


52


and a first W-shaped slot


82


positioned to interrupt an outer peripheral edge


84


of C-shaped sections


50


,


52


. Second extensible link


56


is defined by a second V-shaped slot


81


positioned to interrupt smooth surfaces on edges


62


,


66


of C-shaped sections and a second W-shaped slot

28


,


30


from hub


24


. In the illustrated embodiment, handle support


48


includes a sleeve


90


that extends into an opening bounded by cylindrical wall


70


and an annular flange


92


extending radially outwardly from sleeve


90


to engage a rim


93


provided on hub mount ring


28


so that hub mount rings


28


,


30


are trapped (yet rotatable about hub axis


25


) between left side


22


of seat


12


and annular flange


92


. A similar arrangement is provided on handle support


46


to retain hub mount rings


32
