ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a collapsible canopy which may be used to supply shelter from sun and rain for outdoor activities. More specifically, the present invention relates to a collapsible canopy similar to an umbrella.
In an umbrella-type canopy commercially available for protection from the whether, a flaccid cover is supported by a central standard and is held extended by pivoted ribs attached to the standard. Such umbrella-type canopy can only provide a limited surface area of protection because of the condition of its framework. The framework of an umbrella-type canopy must be changed so that the umbrella-type canopy can provide a large surface area of protection.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a collapsible canopy which can provide an increased surface area of protection and which can be provided with one, two, three, four, or more covers each of which can be expanded or collapsed as a whole.
The collapsible canopy according to the present invention accordingly comprises a post, at least one slide bracket slideably received on the post, and at least one scissor assembly each having a first side and a second side and being formed by a plurality of scissor units connected in end-to-end relation. Each scissor unit is formed by a pair of cross members which are pivotally connected to each other at their midpoints. One of the scissor units at said first side has one cross member pivotally connected at the end thereof to the top end of said post and the other cross member pivotally connected at the end thereof to its respective slide bracket. A plurality of pairs of upper and lower connecting members are provided for each scissor assembly, in which one pair of upper and lower connecting members are pivotally connected to their respective outer ends of two cross members of the scissor unit at the second side, and each of the other pairs of upper and lower connecting members are pivotally connected at some pair of the upper and lower connections of two adjacent scissor units to their respective ends of four cross members. A plurality of cover support members and a plurality of strutting members are arranged for each pair of upper and lower connecting members, in which the plurality of cover support members are pivotally connected at the ends thereof to the upper connecting member, and the plurality of strutting members are each pivotally connected at one end thereof to the lower connecting member and at the other end thereof to the middle portion of its respective cover support member. At least one reeling device each being attached to said post and having a cable fixedly attached to one of the at least one slide bracket is provided for expanding the collapsible canopy.
