  • Patent number: 5168889
    Abstract: The invention provides a simple removable and storable weather and sun covering for a wheelchair. Two embodiments include a soft cover version which can be dismantled and stowed in a container on the wheelchair and a hard top version which can be easily removed and stored when not needed. Common to both covers is a cover support clamp bracket uniquely suited for securing a variety of covers and cover frames to the frame of most any wheelchair. The cover support clamp bracket can be left on the wheelchair even when not in use or easily removed when not needed. A tubular extension fitting the clamping bracket increases wheelchair cover stability. No special frame work retainers are required in the framework of the soft cover such as corner joints or collars as seen in other cover frameworks.

  • Patent number: 5158102
    Abstract: An umbrella frame having two collapsibly protractable structures defining ear-like projections. The umbrella frame has a plurality of ribs and associated pivotally attached struts extendable to define a characteristic dome shaped umbrella. The struts are further attached to a runner axially slidable on a central shaft of the umbrella that causes the outward extension of the struts to push the ribs outwardly when the runner is upwardly moved. In addition, two pairs of braces are respectively pivotally attached on one end to opposing struts either at the same point or at separate locations thereon, and extend through respective guide brackets fixedly attached to respective outer ribs. The other ends of the braces extend beyond the outer dome of the umbrella and are pivotally attached to a swivel coupling that causes loop shaped bending of the braces to define outwardly projecting ears from the characteristic dome shaped umbrella when the struts are extended by upwardly moving the runner.

  • Patent number: 5146940
    Abstract: An umbrella cover for covering a closed umbrella is provided. The umbrella cover comprises a cylindrical roll of a spirally wound strip which may be elongated by axially pulling out the outer end of the the wound strip. The inner end of the wound strip is secured to the ferrule of the umbrella. The strip has formed therein a plurality of parallel slits extending at a predetermined tilt angle in relation to the longitudinal axis of the strip, and a plurality lips which have a configuration capable of engaging with the slit. The strip is wound such that the lip in one turn of the spirally wound strip is engaged with the slit in the adjacent turn of the wound strip so that the lip can slide along the slit upon elongation of the cylindrical roll, and such an engagement of the lips in the slit prevents the wound strip from being excessively pulled out. The strip may comprise two overlaid film tapes each having the slits or the lips formed therein, or one film tape having the both.
