BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates generally to improvement in umbrella construction and, more specifically it relates to a non flip umbrella.
Commonly available umbrella used as a protection against the weather consists of a fabric canopy that is fastened to a skeletal frame with pivotally hinged ribs or braces radiating from a center pole or handle. A movable member defined by a sliding catch pivotally supports the braces of the ribs. The umbrella has a convex dome when open, and can be opened by sliding up or folded by sliding down said sliding catch.
The aforementioned conventional umbrella, though widely accepted satisfactorily by the end-user still encounters one pronounced defect. It has been observed that the fabric canopy is sustained in open or extended position merely by the force of the braces which bear on their ends to the sliding catch and at their outer ends against the respective ribs to which they are connected. Said braces and ribs cooperatively form a linkage-like support for the whole structure. Said linkage-like support is usually subjected by the lateral pressure of the weather which is always exerted against the outer edges of the fabric canopy. During windy weather condition (e.g. typhoon/storm), the fabric canopy together with the supporting ribs tends to flip-over or collapse over when a gale of wind or continuous strong wind blows through the inside of said umbrella thereby totally incapacitating the umbrella giving inconvenience to its user.
In view of the defects found in the utilization of the existing umbrellas, there is therefore a need to positively secure and/or reinforce the ribs and braces of the umbrella so as to preclude the tendency of collapsing over thereof. Accordingly, the present invention contemplates to introduce a guy assembly which could appreciably secure rigidly the ribs of the umbrella and thereby making it capable of positively sustaining the ribs in correct position without flipping over.
Another object of the invention is to provide a non flip umbrella wherein the guy assembly incorporated thereof has an inner end connected to said sliding catch and the outer end connected to said respective ribs.
A further object of the invention is to provide a non flip umbrella which is so simple in structure, permits facile assembly and reliable.
The objects of the invention, and its characteristic features and advantages will be further understood in the following detailed description taken in conjunction with the appended drawings.

FIG. 7(a) (b) (c) is a fragmentary view showing the mode of connecting the guy assembly with the ribs of the umbrella.
DETAILED DESCRIPTION
Referring now in detail to the several views of the drawings wherein like reference numerals designate the same parts throughout, there is illustrated a non flip umbrella which is generally designated by the reference numeral 10. This umbrella 10 conventionally comprises an elongated center pole 11 provided with an apex in the form of a hub 12 encompassingly fixed at the upper end of said center pole 11 and a series of ribs 13 hingely connected to said hub 12 and spacedly radiating from said center pole 11. Movably secured on said center pole 11 and proximately below the hub 12 is the sliding catch generally designated by the reference numeral 14, as in conventional structure, the sliding catch 14, defines a cylindrical sleeve 15 having at the upper terminal end thereof an integral chann
