Definitions

  • the invention relates to an umbrella, more particularly to an automatic spreading umbrella with a handle shaft of considerable strength to prevent bending and.breakage thereof.
  • a first conventional umbrella includes a spring-loaded telescopic handle shaft, a hub mounted on a top end portion of the handle shaft, a rib assembly mounted pivotally at one end to the hub, a lower runner mounted slidably on the handle shaft and movable toward and away from the hub, an upper runner mounted slidably on the handle shaft between the hub and the lower runner, and a stretcher assembly connected operably to the rib assembly and the lower and upper runners.
  • First and second rib spreading coil springs are sleeved on the handle shaft in such a manner that the first rib spreading coil spring is disposed between the hub and the upper runner while the second rib spreading coil spring is disposed between the upper and lower runners.
  • the stretcher assembly When the lower runner is moved away from the hub, such as when folding the umbrella, the stretcher assembly will pull the rib assembly downward to a retracted position, thereby compressing the first and second springs in an axial direction of the handle shaft. When the lower runner is moved toward the hub, the stretcher assembly will push the rib assembly, thereby releasing the first and second springs from compression and consequently permitting the rib assembly to be disposed in a stretched state.
  • first and second springs around the handle shaft prevents the rib assembly from being retracted closely relative to the latter, thereby rendering the size of the folded umbrella to be relatively bulky.
  • a second conventional umbrella includes a spring-loaded telescopic handle shaft, a hub fixed to a top end portion of the handle shaft, a lower runner mounted slidably on the handle shaft, a rib assembly mounted pivotally at one end to the hub, an upper runner mounted slidably on the handle shaft above the lower runner, and a stretcher assembly connected operably to the rib assembly and the upper and lower runners such that the umbrella can be operated so as to dispose the same in unfolded or folded states.
  • a wall surface confining the top end portion of the handle shaft is formed with an axial slot.
  • a slide pin extends through a wall body of the upper runner and the slot so as to limit axial sliding movement of the upper runner on the handle shaft. Formation of the slot weakens the strength of the handle shaft. The longer the slot, the weaker the handle shaft will become.
  • an object of this invention is to provide an automatic spreading umbrella which can overcome the aforementioned disadvantages that are associated with the conventional umbrellas.
  • an umbrella comprises:
  • an automatic spreading umbrella of this invention is shown to include a handle shaft (40), a hub (60), a lower runner (50), a rib assembly (80), a stretcher assembly (100), an upper runner (70), a coiled compression spring (90), and a spreader assembly (200).
  • the handle shaft (40) is a known spring-loaded telescopic handle shaft that has a tubular top end portion (40T) with a distal end surface.
  • a stop member (42) is disposed in the top end portion (40T) and is spaced apart from the distal end surface.
  • the hub (60) is mounted securely on the top end portion (40T) of the handle shaft (40).
  • the lower runner (50) is mounted slidably on the handle shaft (40) and is movable toward and away from the hub (60).
  • the lower runner (50) can be locked releasably on the handle shaft (40) in a known manner so as to retain the umbrella in a folded state (see Fig.2).
  • the lower runner (50) is preferably provided with a radial notch (50R).
  • the handle shaft (40) is provided with a spring-biased catch (40E) at a lower portion thereof to engage the notch (50R) of the lower runner (50), thereby locking the lower runner (50) on the handle shaft (40). Operation of the catch (40E) will result in release of the lower runner (50) from the locked state.
  • the rib assembly (80) is mounted pivotally at one end on the hub (60) in a conventional manner.
  • a canopy (not shown) is mounted on the rib assembly (80) in a manner that is known in the art.
  • the stretcher assembly (100) is connected operably to the rib assembly (80) and the lower runner (50) in a known manner.
  • the upper runner (70) has an enlarged head (72) disposed above the hub (60), and a guide shaft (71) that extends from the enlarged head (72) and into the tubular top end portion (40T) of the handle shaft (40) .
  • the compression spring (90) is sleeved on the guide shaft (71), and has a bottom end (90B) that is disposed in the top end portion (40T) of the handle shaft (40) and that abuts against the stop member (42), and a top end (90T) that extends outwardly of the top end portion (40T) of the handle shaft (40) and that abuts against the head (72) of the upper runner (70).
  • the spreader assembly (200) is connected operably to the rib assembly (80) and the head (72) of the upper runner (70).
  • the stretcher assembly (100) will pull the rib assembly (80) to the folded state, thereby causing the rib assembly (80) to pull the spreader assembly (200) and move the head (72) of the upper runner (70) toward the hub (60) and compress the compression spring (90).
  • the lower runner (50) can be locked on the handle shaft (40) at this time.
  • the compression spring (90) expands and pushes the upper runner (70) away from the hub (60).
  • the spreader assembly (200) then pulls the rib assembly (80) to a stretched state, as best shown in Figure 1, thereby pulling the stretcher assembly (100) to move the lower runner (50) toward the hub (60).
  • the stop member (42) can be a pin which extends through a radial hole formed through the top end portion (40T) of the handle shaft (40). Alternatively, the stop member (42) can be formed integrally with the top end portion (40T).

    einen Speichenaufbau (80), der schwenkbar mit einem Ende an der Buchse (60) befestigt ist,
    einen Streckaufbau (100), der wirksam mit dem Speichenaufbau (80) und dem unteren Schieber (50) verbunden ist,
    eine gewendelte Druckfeder (90), die ein unteres Ende (90B), das an dem oberen Endabschnitt (40T) der Griffstange (40) angeordnet ist und das gegen das Stoppelement (42) anliegt, und ein oberes Ende aufweist, das an dem oberen Schieber (70) anliegt, und
