Definitions

  • the present invention relates to a collapsible umbrella lying flat when closed with a stick having at least two sections adapted to telescope into each other and with at least eight ribs each comprising at least two parts and adapted to telescope and/or fold.
  • FIG. 1 shows a side view of one-half of an opened-up collapsible umbrella according to the invention
  • FIG. 2 shows a plan view of the opened umbrella
  • FIGS. 3 to 12 show a cross section through a possible em bodiment of the notch, runner or auxiliary runner with different arrangements of the pins.
  • an umbrella frame according to the invention which is characterized primarily in that the ends of the ribs, stretchers and possible auxiliary stretchers are linked to the notch runner or auxiliary runner by pins which are inserted into corresponding bores in the notch, runner or possible auxiliary runner.
  • the ends of the ribs, stretchers or auxiliary stretchers arranged at each of the short and long sides of the notch, runner and auxiliary runner are preferably held by one pin.
  • the pins for the long sides there may respectively be provided two short pins.
  • the two longitudinal pins there may be provided two pins lying on either side of the hold for the stick on the longitudinal centerline of the notch, runner or auxiliary runner.
  • the pins lying parallel to the longitudinal centerline are prevented from slipping out by the transverse pins running across at the short sides.
  • the pins lying parallel to the longitudinal centerline that they project into the hole in the notch, runner or auxiliary runner.
  • the pins serve not only to attach the ribs or stretchers but simultaneously serve as a releasable fastener for other parts.
  • at least one of the two pins lying on the longitudinal centerline projects into the hole in the notch, runner or auxiliary runner.
  • replace the two pins with one continuous pin on the longitudinal centerline of the notch so that this pin also passes through the stick.
  • An umbrella frame designed in conformity with the invention results in a collapsible umbrella frame which is flat when closed while the individual parts of the umbrella are especially simple, and consequently can be produced at low costs. Moreover, the individual parts can be assembled quickly in a simple manner.
  • the umbrella frame comprises a stick l with a notch 2 at its upper end. Attended to this notch there are in this embodiment two-piece ribs 5 which support the umbrella cover 3. The ribs are by stretchers 6 attached to the runner 3 which is guided on the stick ll. In the embodiment shown in FIGS. l and 2 there is also provided an auxiliary runner 4 with auxiliary stretchers 7joined to the stretchers 6.
  • the notch 2 is of an elongated shape and is symmetric with regard to a longitudinal centerline L.
  • the ends of the ribs 5 are arranged symmetrically with respect to a transverse axis 0 of the notch 2.
  • This elongated shape and symmetry with respect to the longitudinal centerline L and transverse axis 0 also holds for the runner 3 with stretchers 6 and the auxiliary runner t with auxiliary stretchers 7. This arrangement means that when the umbrella is being opened, no twisting forces will be exerted upon the umbrella cover 8.
  • FIGS. 3 to 12 show various possible designs for the notch 2, runner 3 or auxiliary runner 4 and for the mode of attachment of the ribs 5, stretchers 6 or auxiliary stretchers 7 to the respective holder. Although the 10 different designs are illustrated for the notch 2 and ribs 5, they also apply to the runner 3 with stretchers 6 or the auxiliary runner 4 with auxiliary stretchers 7.
  • FIG. 3 there is depicted the stick 1 to which the notch 2 is fixed.
  • the notch 2 is oblong and symmetric with respect to the longitudinal centerline L and transverse axis 0.
  • the four ribs 5 arranged at the two long sides are linked in pairs to longitudinal pins 9b each running on one side parallel to the longitudinal centerline L.
  • These longitudinal pins 9b run outside hole lla in notch 2 which hole is provided for stick ll.
  • one or both of the langitudinal pins 9b may respectively be replaced by two short pins so that each of these pins holds one rib 5 on the long side.
  • each of these pins 9d links to the notch 2 those ribs 5 on the long sides which lie on one side of the transverse axis 0.
  • the ribs 5 at each short side are attached as before to the pin 9a which simultaneously prevents the respective pin 9d from slipping out.
  • FIGS. 7 and 8 illustrate furthermore that it is possible to fix the notch 2 to the stick l with one or both of the pins 9d. Altemately, this may be achieved by having instead of the two pins 9d a continuous pin 9e along the longitudinal centerline L for all the ribs 5 at the long sides as shown in FIG. 9.
  • FIG. 10 depicts a runner 3 of which that part which carries the ends of the stretchers 6 is joined to a guiding bush 3a.
  • the hole la in the runner 3 for the stick ll thus corresponds to the bore in the bush 3a.
  • a pin 9b extending over the entire length of the runner 3 parallel to the longitudinal centerline L is offset inwardly in such a way that it passes through part of the bush 3a in the manner of a secant. In this way a simple or additional connection of the guiding bush 3a to the runner 3 may be effected.
  • both longitudinal pins 9b could be used to fix the bush 311, as shown in FIG. ill. The same method can be used] to fix the bush of an auxiliary runner.
  • the last embodiment depicted in FIG. 12 shows that in the case of a runner 3 (or auxiliary runner) the ends of the pins 9d lying on the longitudinal centerline L may be used to prevent rotation of the runner 3 on the stick ll. To this end, the ends of the pins 9d project into axial recesses lb in the stick 1, thus holding the runner 3 and preventing it from rotating.
  • a collapsible umbrella frame lying flat when closed which comprises in combination a stick, a first member forming notch means connected to one end of said stick, a second member forming runner means displaceably mounted on said stick and movable toward and away from said first member, and umbrella-cover-supporting means pivotally connected to said members, at least one of said members when viewed in the axial direction of said stick being of substantially greater length than width so that said member has a longitudinal axis along its length, first pin means in said member extending parallel to said longitudinal axis pivotally connecting certain of said supporting means on opposite sides of said member, and second transverse pin means at each end pivotally connecting other of said supporting means to said member, said transverse pin means extending across and blocking the ends of said longitudinal pin means against removal.
  • At least one of said first pin means for pivotally connecting comprises a plurality of pins extending in the longitudinal direction of said at least one member.
  • said first member is provided with a substantially central bore receiving said stick
  • said first pin means for pivotally connecting comprises a plurality of pins on opposite sides of a plane of symmetry both extending through said central bore and transverse to said first member
