Definitions

  • a folding umbrella comprises a telescoping handle, a flexible fabric cover and a number of rib assemblies, with each of the rib assemblies having three segments.
  • the first segment closest to the handle is hollow, and has an end pivotally attached to the handle by a fixed pivot.
  • center segment is slidably disposed within the first segment and the third segment has an end pivotally attached to the center segment.
  • Means are provided for automatically sliding the center rib segment into the first segment and also pivoting the third rib segment to a position forming an acute angle with the first and center rib segments when the umbrella is closed.
  • the first and center rib segments are extended with respect to each other and the third rib segment is held in alignment with the first and second rib segments by a resilient tento the universal joint rides.
  • the umbrella is operated by j means of the sliding pivot. To open the umbrella the sliding pivot is first pulled away from the fixed pivot thus extending the sliding center rib segments with respect to the first segments.
  • the sliding pivot is then pushed toward the fixed pivot thus opening the ribs and applying tension to the resilient tension element inthe pivoting ribs.
  • Locking means are included on the handle to lock the sliding pivot in the open position.
  • the handle comprises a series of three segments having diameter larger in turn and fitted slidably one in another for the purpose of extending when the umbrella is open and sliding into one another when the umbrella is closed.
  • the invention relates in general to foldable umbrellas and is directed in particular to an umbrella foldable compactly in three parts.
  • Most conventional folding umbrellas have a structure in which the ribs can be folded into two segments.
  • Very few folding umbrellas have a structure in which the ribs slide to stretch or contract or in which the ribs may be folded into three segments.
  • the ribs will automatically stretch or bend with the opening or closing of the umbrella so that the trouble of stretching or bending of the ribs by hand is eliminated.
  • an automatic mechanism has not been available for umbrellas of the type in which the ribs slide to stretch or contract or in which the ribs may be folded into three segments.
  • An object of this invention is to provide. a folding umbrella having three part ribs with automatic means. for opening and closing the ribs.
  • Another object of this invention is to provide an umbrella having ribs wh1ch slide to stretch or contract with an automatic means for opening and closing the ribs.
  • Patented July 29, 1969 "ice Another object of this invention is to provide an extremely compact folding umbrella.
  • Another object of this invention is to provide an umbrella foldable in three segments wherein the opening and closing operations can be carried out quickly and smoothly by a simple mechanism.
  • FIG. 1 is a side view of an umbrella incorporating the invention showing a rib in a partially closed position.
  • FIG. 2 is a side view of an umbrella incorporating the invention showing a rib in the open position.
  • FIG. 3 is an enlarged fragmentary view showing part of a rib in the partially closed position.
  • FIG. 4 is an enlarged side view of the upper end part of a stay rib with the umbrella in the open position.
  • FIG. 5 is an enlarged perspective view of a joint piece to be attached to the upper end part of the stay rib shown in FIG. 4.
  • the umbrella is shown as having a handle comprising an upper handle 1, an intermediate handle 2 and a lower handle 3. These three handles are of diameters larger in turn and are fitted slidably in one another.
  • An upper pivot ring 4 is fixed to the upper end of the upper handle 1 and has main ribs 6 pivoted thereto through a retaining ring 5.
  • An intermediate pivot ring 7 is fitted slidably on the outer periphery of the upper handle 1.
  • a lower pivot ring 8 is provided with a longer upper tube 8a and a lower tube 8b having an engaging slot.
  • An engaging piec 9 is resiliently fitted on the upper handle 1 and provided with an upper slow sloped projection 9a, a lower slow sloped projection 9b and an engaging notch 90. The upper slow sloped projection 9a is to fit into the engaging slot in the lower tube 8b when the lower pivot ring 8 is pushed up to the uppermost position.
  • a slider rib 10 is slidably inserted into the main rib 6 and has a stay ri-b universal joint 11 disposed at the upper end.
  • the stay rib universal joint 11 is formed of a metal sheet folded into half to provide symmetrical right and left parts including a projection 11a which is to make it easy to pass through a short guide tube 12-fitted to the outer periphery of the lower end of the main rib 6 and toimprove the stability, a narrow base part 11b following the projection 1111, a projecting part 11d provided with a pin hole 11c and an engaging projection 11:: at the upper end.
  • a retaining tube 13 encloses the stay rib universal joint 11 and lower end portion of themain rib 6.
  • a slot 13a in the tube 13 receives the projecting part lid of the stay rib universal joint 11.
  • a notch at the left end of the tube 13 is engaged with the engaging projection 11e of the stay rib universal joint 11.
  • a stay rib 14 is rockably connected at its lower end with the lower pivot ring 8 through a retaining ring 15.
  • a joint piece 16 provided with an L-shaped slot 16a is fixed tothe upper end of the stay rib.
  • a waveshaped part 161 is formed on the lower side of the joint piece 16 so as to make it easy to fix the joint piece to the stay rib by crimping the stay rib.
  • the stay rib is made rockable with respect to the universal joint by fitting the L-shaped slot 16a to a pin 17 extending through the pin hole of the stay rib universal joint 11.
  • An auxiliary stay rib 18 is rockably connected at its upper end with the intermediate pivot ring 7 through a retaining ring 19 and is pivotally connected at the lower end through a pin 20 to a bearing piece 21 fixed on the stay rib 14.
  • a tip rib 22 is provided at its upper end with a fitting 22a which is pivoted upward slidably through pivotally connected by a pin 24 to a bearing piece 23 fixed to the lower end of the slider rib 10.
  • a bent connecting piece 25 is connected to the fitting 22a at the upper end of the tip rib 22 through a pin 26.
  • An operating wire 28 is connected at one end to the other end of said bent connecting piece 25 through a tension spring 27.
  • a hook part 28a formed at the other end of the operating wire 28 is slidably fitted in the L-shaped slot 16a.
  • FIG. 2 shows the umbrella as opened.
  • the hook part 28a of the operating wire 28 is engaged with the elbow part B of the L-shaped slot 16a in the joint piece 16 and one end part A of the L-shaped slot 16a is engaged with the pin 17.
  • the tip rib 22 is pulled by the tension of the tension spring 27 so as to extend to be aligned with the slider rib 10.
  • the umbrella While the umbrella is opened, if the engaging piece 9 is pushed in with a finger, due to the tension of the stretched cloth (not illustrated), the umbrella will move to close. If the lower tackle tube 8b is gripped with fingers and the lower tackle 8 is made to slide downward, toward handle 3, the umbrella will gradually close. At this time, the hook part 28a will slide toward the end part C (see FIGS, 1 and on the stay rib side in the L-shaped slot 16a. Then, if the upper tackle 4 is gripped with one hand and the bottom of the lower handle 3 is strongly pushed with the other hand, the intermediate handle 2 and the lower handle 3 will be moved to cover the outer periphery of the upper handle 1 and at the same time the slider rib will slide upward within the main rib 6.
  • the projection 11a will move through the short guide tube 12. While the umbrella is closed, the bent corner part B of the L-shaped slot 16a will engage with the pin 17. While the umbrella is closed as shown in FIGS. 1 and 3, as there will be no force of the tension spring 27, the tip rib 22 will be able to be freely rocked upward to be folded.
  • the lower handle 3 and the intermediate handle 2 should be pulled out downward and the lower tackle 8 should be made to slide to the lowermost position. Then, if the lower tackle 8 is raised, the intermediate tackle 7 will also rise with it, the stay ribs 14 will expand and the umbrella will open. In such case, with the tension of the tension spring 27, the tip rib 22 will extend to be aligned with the main rib and slider rib and the stay rib and auxiliary stay rib 18 will be tensioned.
