An umbrella includes a shaft, a notch, a runner, a plurality of ribs, a plurality of stretchers, a plurality of tips and an umbrella cloth. The notch is fixed with the shaft, the runner slides on the shaft, the ribs are connected with the notch pivotally, the stretchers are pivotally connected between the runner and the ribs, the tips are fixed to the ribs, two ribs are inserted into each tip, and there is a clearance between the two ribs inserted into the same tip, umbrella cloth is fixed with ribs, ribs are covered with umbrella cloth, and umbrella cloth has a plurality of folded parts passing through the clearances respectively. Accordingly, the umbrella cloth of the invention is different from a conventional umbrella cloth which is made by sewing together many small panels of waterproof cloth with each other, so that the umbrella cloth has higher waterproof ability.
摘要:
A method of forming an umbrella canopy having a substantially continuously aligned decorative pattern displayed thereon, wherein the canopy is of the type used on large, outdoor and/or recreational umbrellas. The method includes forming an elongated sheet of canopy material with the decorative pattern displayed along a continuous portion of the length thereof. The decorative pattern is defined by a plurality of substantially equivalent, successively disposed pattern segments, wherein adjacent ones of such pattern segments are inverted relative to one another. The canopy sections used to construct the final product of the umbrella canopy are formed by extending each of a plurality of bias cuts along the entire width of the sheet of canopy material and at predetermined angular orientations to a central longitudinal axis of the sheet. The separated canopy sections are then arranged into a substantially common orientation and interconnected to collectively correspond to an intended configuration of the umbrella canopy being formed.

This invention relates to a device for accurate view of the entire sky from the horizon regardless of the location on earth of the user. The device is an umbrella type design that a person stands underneath and views the night sky through the device. The device includes an umbrella portion and a removably attachable drape portion. The umbrella portion provides the structure of the device and the drape provides the mapped out night sky thereon which may be removably detachable and adjustable for an accurate depiction of the sky.

An umbrella cover if formed from a unitary piece of material, an octagonal piece of material having eight corners, which may be decorated, such as by printing, without image segmentation. The cover has eight generally triangular slits therein extending one from each corner of the octagon toward, but in spaced relation from, a center point, a point of each triangle at the inner end of the slit. The sides of each slit are sewn together to form a dart. The cover is tacked to an eight-rib frame, with each dart tacked adjacent a flexion point in a rib.

A canopy system including a canopy frame and a canopy cover supported by the canopy frame. The canopy cover includes an inner solid portion, an outer solid portion, and a meshed portion disposed between the inner and outer solid portions and disposed proximately to an outer periphery of the canopy cover.

The umbrella has a tie strap with a width preferably of at least about one-half the length of a rib linkage's cover rib so that the tie strap tends to function as a cover for a collapsed and furled umbrella. The tie strap preferably has a centerline that is substantially normal to the umbrella's centerpost when the umbrella is fully collapsed so that when the tie strap is wrapped around the umbrella, the cover rib linkages are neatly held with less bunching being visible to the user's eye than if a prior art tie strap were used.
摘要:
A method of eliminating corrugation in central umbrella cover, being made of a plain weave cloth, in which the weft has no stretchability, while the warp has a slight stretchability; before the umbrella cloth being cut into an umbrella cover, the umbrella cover and the main rib are set a different angle of ten degrees; the tail end of the main ribs and the sewing points of the umbrella cloth are not fallen on the parallel line of the warp or the weft; from the sewing points to the central part of the ribs, there are different length so as to balance the tension of various stretch points; the edge of the umbrella cover is cut out and sewed properly so as to provide suitable corrugation-proof. When the umbrella is opened, the central portion of the umbrella cover would not have corrugation and looseness because of the main ribs having a slight curvature, and the oblique weave mesh able to balance the stretched tension.
摘要:
A garden umbrella employing an upper canopy extending from the top of the umbrella pole to the middle of long canopy ribs, and a lower outer canopy extending in a ring around the outer part of the umbrella and having long sleeves sewn across the canopy in a radial pattern for receiving a canopy rib in each sleeve. The canopy ribs are pivotally connected to a runner notch, while the other ends of the canopy ribs are received in the canopy sleeves. Stretcher ribs are pivotally connected between each canopy rib and a top ribholder secured at the top of the umbrella pole. The rib and runner notch configuration, together with the outer canopy, permit very easy opening and closing of the umbrella by movement of the runner notch between its upper, open umbrella position and its lower, closed umbrella position. The lower canopy comprises panels sewn together along the bottom of each rib such that a wind vent space is formed with the upper canopy which extends to the top of each rib. The lower canopy panels also include metal rods sewn therein at selected locations for maintaining the shape and handling of the canopy. Counterweights are provided in the canopy ribs to facilitate opening of the umbrella. Also, a strap is designed to wrap the lower canopy when the umbrella is closed.

A retractable dual solar screen which is supported by adjustable poles above the tanner or sun bather and selectively screens out harmful UV radiation and/or provides shade without UV screening. The first screen filters UV radiation and the second screen filters a broad spectrum of sunlight. In addition, an adjustable mechanism allows the planes of the screens to direct the flow of air currents such that a wind acceleration effect is achieved which causes accelerated airflow over the user, thereby cooling the body temperature of the user. The height of the device is adjustable.
