Definitions

  • This invention relates to umbrellas and more specifically to a distinctively special umbrella that is characterized as including a structure with a minimum number of parts so arranged as to retain the function of a many-part umbrella even though parts of a conventional umbrella have been eliminated.
  • the inner ends of the canopy supporting ribs are pivotally connected to ring slidable in a hollow shaft.
  • the instant invention includes a canopy which is free of supporting ribs but does cooperate with a series of radially extending members designated in this specification as chords in the sense that these chords are members which subtend an arc-like length of canopy and are generally horizontal as in the supporting framework of a bridge.
  • Fig. 1 is a plan view taken from the top of the opened umbrella.
  • Fig. 2 is a vertical section, with parts in elevation, generally taken along line A-A of Fig. 1 and looking in the direction of the arrows.
  • Fig. 3 is a plan view, with parts broken away, illustrating a pin-wheel configuration for the pivotal connection of the chords to the slidable ring.
  • the umbrella canopy is made up of a plurality of triangles, the bases of which form the continuous outer margin of the canopy and the apices of which are joined together to form that inner portion of the canopy which covers the top of the umbrella staff.
  • the sides of the canopy triangles are seamed together so that the canopy in open position is in the general form of a multifaceted pyramid.
  • the canopy is in the form of a hexagonal pyramid comprising six triangular facets.
  • the umbrella is illustrated in open position and the canopy is shown extended over the top of the staff and affixed to the outer ends of the radially, generally horizontally and somewhat downwardly outstretched chords.
  • chords are each pivotally connected to the ring and tube assembly and the ring is integrally connected to the tube and is longitudinally slidable therewith over the coaxial umbrella staff.
  • the ring and tube assembly is shown in its lowermost locked position with the canopy open. In this position the spring-pressed latch extends outwardly from the staff and protrudes through the vertical slot in the tube near its lower end which does not quite reach the umbrella handle.
  • the canopy fabric When the umbrella is latched in open position, the canopy fabric will be in tension and the chords will be cooperating therewith to form structural triangulation with the upper end of the staff.
  • the canopy fabric, the chords, and the staff form structural triangles or triangular structures.
  • chord members which in their extended position are generally horizontal and somewhat lower at their outer ends are preferably somewhat flexible but they may also be relatively rigid
  • SUBSTITUTE SHEET SUBSTITUTE SHEET and still serve to create tension in the canopy fabric when the umbrella is in open position. This structure functions as desired even under windy conditions.
  • the umbrella includes a canopy of hexagonal pyramid form corresponding to six chord members extending from the staff. It is to be understood that the base of the pyramid may be a square corresponding to four chord members or an octagon corresponding to eight chord members or the canopy may be of a higher order of polygonal base pyramid with a corresponding number of chord members.
  • the desired triangular structure is formed by ribs immediately in contact with the underside of the canopy, links pivotally connected to ribs and to the slidable ring and the staff.
  • the hinging or pivotal connection of the inner ends of the chords to the slidable ring may be effected in a conventional manner, the pivotal connection may also be made in pin-wheel configuration.

Abstract

Un parapluie comprend une calotte (calotte ouverte de parapluie), un manche (manche coaxial de parapluie) et une série d'éléments radiaux semblables à des cordes (cordes radiales) reliés par une extrémité au bord de la calotte et par l'extrémité opposée à un ensemble de tube et d'anneau verrouillable coaxialement monté sur le manche de façon à glisser sur celui-ci. Les cordes et la calotte forment des triangles structuraux sous tension lorsque le parapluie est ouvert.
