Definitions

  • This invention relates to an improved folding mechanism for a flat top umbrella.
  • a favorite collapsible flat top umbrella as shown in Figure 3, comprises a shaft (13) provided with a fixed pivot ring (131) serving for the pivotal joints of the proximal first main ribs (10) and a slidable pivot ring (12) serving for the pivotal joints of the support ribs (11).
  • main ribs refers to the ribs which serve to maintain the shape of the canopy of the umbrella
  • support ribs refers to the ribs for supporting the main ribs to maintain the open state of the umbrella.
  • a second main rib (9) is provided with a pivotal joint (92), to which the distal end of lower rib (11) is pivoted, at a distance from its proximal end (91), where the distal end of a bridging rib (93) is pivoted, the proximal end of the bridging rib. (93) being pivoted to the first main rib (10) at a position spaced from its distal end which is pivoted to the lower rib (11) at a distance from its distal end (92).
  • bridging rib refers to a link of which the both ends are respectively pivoted to two ribs which are otherwise disconnected with each other mechanically.
  • Such umbrella has a disadvantage that the collapsed structure is unsatisfactorily long, since the collapsed length depends on the length of the second main rib (9). As a result, the umbrella cannot be folded up and shortened to a length short enough to be received in a handbag or the like. If the umbrella is shaved a fraction to meet this requirement, the rib will have to be shortened, thus the canopy may become too small to provide sufficient shielding from rain drops or shading of sunshine.
  • the problem of the aforesaid flat-top umbrella is solved by means of pivoting the most proximal upper rib and the lower rib at a distance from their distal ends.
  • the umbrella also comprises a shaft (8), a fixed pivot ring (81) and a slidable pivot ring (7) with a spring loaded check (82).
  • the inner (most proximal) main rib (3) and the support rib (6) pivot each other at a distance from their distal ends.
  • the distal end of first main rib (3) has two pivotal joints (31) (32) respectively pivoting the proximal ends of two parallel (but very close to each other) middle main ribs (2) (4.), of which the distal ends are respectively pivoted to the two pivotal joints (121) (122) of a pivoter (12), to which the proximal end of the outer main rib (1) (the most distal main rib) is fixed.
  • a bridging rib (5) bridges the distal end of support rib (6) and a pivotal joint (25) on the upper middle main rib (2) at a distance from its proximal end (32).
  • the distal sections of inner main rib (3) and the pivoter (12) define a second parallelogram.
  • FIG 4 A modified, equally satisfactory embodiment is seen in Figure 4, in which there are also two parallelograms defined by the framework.
  • the upper middle main rib (2A) is longer than the lower middle main rib (4A), extending beyond its pivotal point (25A) with the bridging rib (5A) and reaching an end pivotal point (32A) with main rib (3).
  • the shorter lower middle main rib (4A) only extends to an end pivotal point (31A) with (5A).
