Definitions

  • An umbrella frame of the parallelogram type which includes a stick, a crown at one end of the stick, a main runner slidable on the stick, and an auxiliary runner slidable on the stick between the main runner and the crown.
  • Stretcher members are hingedly connected to the main runner, while strut members are hinged to the auxiliary member and each to a mid point of each stretcher member.
  • a dome rib is pivotally connected to each end of a stretcher member and extends inwardly from the end of the stretcher member a short distance where it is connected to a linkage member which in turn is hingedly connected to the strut member forming a quadrilateral parallelogram linkage with the dome rib.
  • FIG 3 UMBRELLA FRAME BACKGROUND OF THE INVENTION 1.
  • the present invention relates to an umbrella, and more particularly, to an umbrella frame of the parallelogram type.
  • the covering material is, therefore, furled and folded against the stick, particularly that portion of the material between the crown and the dome rib end. That section of the material is caught between the folded strut and stretcher member against the stick.
  • the disadvantage of this construction is that when the umbrella covering material is wet and the user wishes to close the umbrella, there is no alternative but to fold the covering material up against the stick as described above.
  • the dome ribs may be closed against the stick without having to telescope the dome ribs and furl the covering material allowing the covering material to be stretched fully along the length of the stick enabling it to dry more easily.
  • the frame immediately folds against the stick when it is not in a fully opened position. When the fabric is in a moist condition, it will not dry easily when it is folded and furled up against the stick as described above.
  • an umbrella stick a crown at one end of the stick, a main runner slidable on the stick, stretcher members hinged to the crown, an auxiliary runner slidable on the stick between the main runner and the crown, strut members hinged to the auxiliary runner and each to mid points on each stretcher member, dome ribs hinged to the end of the stretcher member, wherein each dome rib extends inwardly a short distance from the hinge point with the stretcher member. and link members hinged to the extension of the dome rib and to the strut members to provide a parallelogram linkage therebetween.
  • resilient type fingers may be connected to the crown to allow the fabric to mushroom outwardly when the umbrella is being closed and collapsed in its smallest package position.
  • FIG. 1 is a side elevational schematic view of an umbrella frame in accordance with the present invention which is in an open position;
  • FIG. 2 is an enlarged fragmentary enlarged detail view of the umbrella shown in the position of FIG. 1;
  • FIG. 2A is a radial cross-section taken along line 2A-2A of FIG. 2;
  • FIG. 3 is a further enlarged view showing the umbrella frame in a closed, but not completely collapsed, position
  • FIG. 4 is a view similar to FIG. 3, but showing the umbrella in its closed collapsed position.
  • an umbrella stick 1 comprising two telescopic sections 2 and 3. Both stick sections 2 and 3 are of polygonal, preferably hexagonal, cross-section so as to prevent rotation of one stick section relative to the other.
  • a locking detent device 4 is provided between the sticks in order to temporarily lock the umbrella sticks in an extended position.
  • a handle 5 is attached to the free end of stick section 3 as shown in the drawings.
  • a crown 6 is attached to the stick section 3.
  • a main runner 24 slides on the stick 1 and a lock lever 37 is adapted to engage an opening Ra in the stick section 3 when the umbrella is in its open position.
  • the main runner 24 includes a bore 24 which has a crosssection similar to the cross-section of the stick 1.
  • a plurality of stretcher members 25 are hinged to the flange 26 of the runner 24.
  • An auxiliary runner 27 slides on the stick between the runner 24 and the crown 6.
  • the auxiliary runner also defines a center bore 27' having a cross-section similar to the cross-section of stick section 3.
  • the auxiliary runner includes a substantially cylindrical sleeve 27" and a flange 28.
  • Strut members 29 are hinged to the flange 28.
  • Each strut is hinged to a stretcher member 25 by means of a hinge pin 30 midway of a stretcher 25.
  • a dome rib hinge member 14 is hingedly mounted to the end of each stretcher member 25 by means of hinge pin 16.
  • the dome rib hinge member 14 includes an extension 19 to which a link member 31 is hinged at 15.
  • the link member 31 is also hinged at its other end to the strut member 29 at hinge pin 33.
  • the link 31, a portion of the strut 29 between the hinge pins 33 and 30, the stretcher member 25 between the hinge pins 30 and 16, and the dome rib hinge member 14 define a parallelogram structure p.
  • a dome rib 7 including a rod of circular cross-section 7b and the dome rib tip 23 is fitted in a sleeve 34 in the dome rib hinge member 14.
  • the angle at which the dome rib 7 lays is determined by the parallelogram linkage described above.
  • the umbrella may be provided with a crown flange 50 into which spring-like fingers 51 are provided, to form the cover material 20 into a mushroom when the umbrella is being collapsed.
  • the main runner 26 includes a sleeve extension 36 which acts as a spacer for the main runner whenthe umbrella is in an open position.
  • a fabric cover is provided over the frame and is attached centrally by the crown 6 including the cap 53 and the annular flange 50.
  • the fabric is also attached in the area of the dome rib hinge members 14 by means of threads 21 and also to the dome rib tips 23.
  • One of the struts 29 can be provided with an opening device including a pawl 59 fixed in a U-shaped structure and including an engaging head 54.
  • the pawl 54 is spring loaded when the umbrella is in its closed position and as the runner is released from a position shown in FIG. 4, the pawl pushes the strut 29 away from the auxiliary runner sleeve 27' and thereby initially opens the parallelogram structure.
  • An umbrella including a frame having a telescopic stick comprising at least two axially collapsible sections, a crown at one end of the stick, a main runner slidable on the stick, an auxiliary runner slidable on the stick between the main runner and the crown, means associated with the main runner and the stick for preventing rotation of the auxiliary runner relative to the stick but allowing axial sliding movement of the auxiliary runner on the stick, stretcher members hinged to the main runner, strut members hinged to the auxiliary runner and to the stretcher members, a non-telescopic.
  • the means associated with the auxiliary runner, and the stick for preventing rotation include a surfaceof polygonal cross-section onthe stick and an inner bore in the auxiliary runner-having a similar cross-sectionto that, '7" d ofthe stick.
