Definitions
- a collapsible umbrella of the type including framedefining two section ribs in which the outer rib sections are slideable along the inner rib sections between extended and contracted positions and a cover overlying the frame and secured to the umbrella notch and the inner and outer ends of the outer ribs, is provided with a spreader member including a hub mounted on the notch and outwardly sprung radially projecting resilient fingers underlying the crown of the cover.
- the hub and fingers are integrally formed of a synthetic polymeric resin and the fingers are interconnected by pliable flexible connectors which may be integrally formed with the fingers and are positioned between the unbrella ribs and cover, the fingers interdigitating the ribs.
- the present invention relates generally to improvements in umbrellas and it relates particularly to an improved collapsible umbrella provided with a mechanism facilitating the compact shaping of the umbrella cover attendant to the collapsing of the umbrella.
- Collapsible umbrellas generally include a shaft with telescoping sections permitting longitudinal extension and contraction thereof and ribs which are likewise formed of two sections relatively movable between longitudinally extended and contracted positions.
- rib outer sections are slideable along the rib inner, notch-pivoted sections and are hinged at their inner ends to spreaders which are connected to the runner.
- the umbrella cover is mounted at its center to the notch and is connected at points along its periphery and between its center and periphery respectively to the outer and inner ends of the outer rib sections.
- the collapsible umbrella of the above type possesses an important drawback and disadvantage.
- the inner section of the umbrella cover With the collapse of the closed umbrella frame the inner section of the umbrella cover is generally bunched into a bulky condition and must be manually reformed and compacted to permit the insertion of the collapsed umbrella into a mating sheath or envelope.
- This umbrella cover shaping operation is, at its best, awkward, inconvenient and time consuming, requiring a high degree of manual dexterity for optimum results and otherwise leaving much to be desired.
- Another object of the present invention is to provide an improved collapsible umbrella.
- Still another object of the present invention is to provide an improved collapsible umbrella of type provided with longitudinally contractable two piece ribs.
- a further object of the present invention is to provide an improved collapsible umbrella provided with means for shaping the umbrella cover attendant the collapse of the umbrella to facilitate the application of a cover sheath thereover.
- Still a further object of the presentinvention is to provide a collapsible umbrella of the above nature having a cover-shaping mechanism characterized by its simplicity, reliability, ruggedness, convenience, ease of operation and low cost.
- a collapsible umbrella comprising a shaft, a notch mounted on said shaft, a plurality of longitudinally contractable ribs hinged attheir inner ends to said notch and swingable between an open position extending outwardly from said notch and a closed position extending proximate said shaft, elements slideable along said ribs between positions proximate and remote from said notch with the contraction and extension respectively of said ribs, a cover member overlying said ribs and secured at its outer border to the outer ends of said ribs and at points between the center and periphery of said cover to said slide elements, said cover member including a crown section between the center of said cover and the points thereof secured to said slide elements, and fingers interdigitating the ribs and connected by flexible elements for resiliently outwardly spreading and maintaining said cover crown section when said ribs are in their closed contracted condition.
- the notch includes a circular base to the border of which the umbrella ribs are hinged and an integrally formed upwardly directed externally threaded hollow cylindrical section mounted on the umbrella shaft.
- the umbrella cover has a central opening engaged by a grommet which registers with the notch and cylindrical section and is locked in position by a screw cap engaging the threaded cylindrical section.
- the umbrella ribs include inner sections and outer sections longitudinally slideable along the respective inner sections, the umbrella cover being secured at its periphery and at inwardly spaced points to the outer ribs inner and outer ends.
- the cover crown spreading means includes an annulus or hub sandwiched between the notch base and the cover grommet and resilient fingers projecting radially from the hub and sprung outwardly.
- the resilient fingers may be loops or sector-shaped elements formed of spring wire, resilient arms formed of synthetic organic ploymeric resins, or the like.
- the resilient fingers may straddle or interdigitate the ribs and in the latter case are provided with flexible connector elements which may be integrally formed with the fingers and overlie the ribs.
- the resilient fingers When the umbrella is closed, the resilient fingers are pressed inwardly by the overlying umbrella cover but upon longitudinal contraction of the ribs the upper or inner part of the cover is released and is spread uniformly outwardly by the resilient fingers and assumes an open dome or mushroom shape.
- the resilient open crown is easily and rapidly collapsed into a compact uniform condition by pressing axially downwardly on the cover crown to collapse the resilient fingers which assures the proper shaping of the crown in a manner which is optimum for ensheathing the collapsed umbrella.
