  • a base end of the connecting rib f is pivotally connected to the support rib d at its intermediate portion.
  • a base end of the end rib g is pivotally connected to a tip end of the connecting rib f through a connecting means and a tip end of the receiving rib e is pivotally connected to the end rib 3 near the base end thereof.
  • the rib assembly comprises the support rib, the receiving rib, the end rib and the connecting rib which are so assembled as to form a quadrilateral Q when the umbrella is opened.
  • the length of each side of the quadrilateral must be strictly determined in order that the umbrella can be neatly folded. Accordingly, it is required to process each rib very precisely.
  • the connecting rib f is extremely short in the umbrella of this kind, it is difficult to process such short ribs at each end thereof for making connecting portions thereof. In addition it is required to manufacture such special short ribs, leading to high cost in manufacturing.
  • the conventional folding umbrella as shown in FIG. 1 and FIG. 6 has such a rib structure that in the open position of the umbrella, the receiving rib is held at an acute angle to the center rod.
  • a considerably strong force is needed at the end of opening operation, which has made the umbrella of this type unsuitable for ladies and children.
  • the opening operation can be facilitated by providing a substantially right angle between the receiving rib e and the center rod a as explained'in detail 4 in the following.
  • FIG. 6 a receiving rib e is at an acute angle to a center rod 0 in the open position
  • FIG. 7 a receiving rib e is at a substantially right angle to a center rod 11 in the open position.
  • 0, designates the angle defined by the receiving rib e and the center rod a in FIG. 6, and 0, is an acute angle.
  • 0, designates the angle defined by the extension line of the receiving rib e and the line normal to the end rib g in FIG. 6, and 0 6 90.
  • the umbrella can be opened.
  • FIGS. 2 to 5 there is illustrated a construction of a folding umbrella according to the present invention.
  • Numeral 1 represents a center rod
  • numeral 2 an upper rib-holder
  • numeral 3 a running tube which has a length sufficient to reach the upper rib-holder 2 when the umbrella is opened
  • numeral 4 a lower rib-holder fixedly fitted around said running tube 3
  • numeral 5 intermediate rib-holder slidably mounted on said running tube
  • numeral 3a a projection formed on said running tube 3 in order to prevent said intermediate rib-holder 5 from slipping out of the posi tion.
  • the running tube may be provided with a radially extending portion as shown in FIG. 5 at its upper portion for the same purpose.
  • a folding umbrella in which a longer rib (a sliding rib) is employed as a connecting rib instead of such a short connecting rib as employed in a conventional folding umbrella.
  • Said connecting rib 8 is not connected to the support rib 6 but crosses the support rib to extend to the intermediate rib-holder 5.
  • a base end of said connecting rib is pivotally connected to said intermediate rib-holder 5 which is slidably provided between the upper rib-holder 2 and the lower rib-holder 4.
  • At least one side of the quadrilateral Q should be variable to give the umbrella a beautiful appearance in its open position and to collapse or fold the umbrella neatly.
  • a tip end of the receiving rib 7 is pivotally connected to the sliding means 10 provided at the portion where the end rib meets with the receiving rib.
  • a base end thereof is pivotally connected to the lower rib-holder 4.
  • the end rib 9 is pivotally connected to a tip end of the connecting rib 8 through the connecting means 9a.
  • the sliding means'lt) is slidably titted on the end rib 9.
  • the receiving rib 7 is pivotally connected to said slid- .ing means 10 and the connecting rib slidably crosses the support rib.
  • the support rib 6 is, as can be seen from FIG. 4, composed of two parallel rib members, an upper end of said support rib being pivotally connectedto the upper ribholder 2 and a lower end being pivotally connected to the receiving rib 7 at its intermediate portion.
  • the support rib 6 is composed of two parallel rib members and the connecting rib 8 is slidably inserted therebetween
  • the connecting rib may be composed of two parallel rib members and the support rib may be slidably inserted therebetween.
  • the stop 9b is formed in order to prevent the sliding means 10 from sliding further to the direction of the tip end of the end rib than the required position during the operation of opening.
  • the receiving rib is kept at a substantially right angle to the center rod 1 in the open position, thereby enables the umbrella to be opened with less force than that needed for opening a conventional folding umbrella. Without the stop, the connecting rib and the receiving rib are in an unstable state.
  • FIGS. 3A and 38 there are described other examples for a rib assembly according to the present invention.
  • the connecting means'9a is pivotally connected to a tip end of the connecting rib 8 and a tip end of the receiving rib is pivotally connected to the sliding means 10 which is a part of said end rib 9 or an extension integrally formed with the end rib 9 at its base portion.
