Definitions

  • This invention relates to self-closing umbrellas and more particularly to umbrellas of the type in which at least one spring is set under tension when the umbrella is opened by human force, and is then held under tension by a lock mechanism, the lock mechanism being releasable manually. Closing of the umbrella is then effected by releasing the lock mechanism, whereupon the force of the spring will ⁇ automatically close the roof.
  • umbrellas of the type referred to the opening of the roof require considerable fo-rce and is therefore felt to be inconvenient. Also, many users of umbrellas will sometimes prefer to handle an umbrella in the conventional way, that is by moving a runner or sleeve up or down the stick. For these reasons, self-closing umbrellas have heretofore been of limited use only.
  • FIG. l is a diagrammatic view of an umbrella representing a rst embodiment of my invention, showing the umbrella closed;
  • FIG. 2 is a diagrammatic 'View of the umbrella illus trated in FIG. l, showing the position of the parts after opening the cover by placing the tip of the umbrella on the ground and pressing the handle downwards;
  • FIG. 3 is a diagrammatic view of the umbrella illustrated in FIG. 1, showing the position of the parts after opening the umbrella in the same way as an ordinary umbrella is opened;

  • FIG. l5 is a modiii-cation of the embodiment shown in FIGS. ll to 14, showing the upper of the umbrella with roof open.
  • the umbrella stick consists of two tubular parts -20 and Z1 which are telescopically insertabtle one within the other, these parts being best seen from FIG. 3,
  • Part 20 carries a crown 22 to which the ribs 23 are hinged or pivoted.
  • a helical spring 24 FIGS. 4 and 8 is disposed in the interior of the tubular part 2.0; this spring extends up to the tip 25 of the stick is supported at one end by ⁇ an end face 26 of the tip and at the other end by means of ⁇ a plate 27 -fixed to the end of a rod 2S.
  • Rod 2-8 extends through the interior of the stick nearly down to the handle 29 and is fixed at its lower end by a transverse pin 30 (FIG.
  • Pawl 31 being pivoted at 32 and acted upon by ⁇ a leaf spring 33, has a catch 34 which engages an opening 35 in stick part 20.
  • the pawl 31 also has a button 36 iiXed to it which when pressed disengages catch 34, thus releasing the stick parts 20 and Z1.
  • the spring 24 then comes into action and pushes the stick parts 20' and 2l apart.
  • the rod 28I is offset from the axis of the stick; the rod is formed near its lower end with a longitudinal slot 67 which provides a passage for the pin 32 of the pawl 31.
  • a runner or sleeve 38 is longitudinally displaceable on the stick.
  • Struts 40 are hinged or pivoted at 39 to the sleeve 38 and are connected by hinges or pivots y4I to the ribs 23 to serve for opening and supporting the cover in the usual manner, the cover not being shown for simplicity.
  • Sleeve 28 carries a locking pawl 42 which is pivoted at 41 and is provided with .a button 43 and a catch portion 44.
  • catch 44 engages an opening ⁇ 45 in sleeve 38 and enters into an opening 46 in the Wall of stick part 21.
  • a coil spring 47 (FIG. 6) tends to hold pawl 4Z in the locked position.
  • In the wall of the stick part 21 there is provided a further opening 48 for the catch 44, as shown in FIG. 8.
  • Catch 44 engages this opening when the umbrella is in the spread position shown in FIG. 3.
  • the umbrella After the umbrella hasY been opened in this way, it may be closed again by releasing pawl 42 and bringing the sleeve 38 again into the position shown in FIGS. 1 and 6.
  • the umbrella after having being opened may instead be prepared for automatic closing by one hand just by placing tip 25 on the ground and telescoping the stick, spring 24 being compressed thereby, without lirst actuating pawl 42 so that the inverted sleeve 38 is moved downwardly along with outer tubular part 21 along inner tubular part 20. The umbrella is thereby brought directly from the position shown in FIG. 3 to the position shown in FIG. 2, the cover remaining open.
  • Stick parts 20 and 21 are prevented from relative rotation.
  • longitudinal and interengaging ribs 49 and 5t) in parts 20 and 21 may be provided, as shown in FIG. 9.
  • Sleeve 38 can similarly be prevented from rotation, in order to ensure that the catch 34 engages the openings 46 yand 48, although it has little tendency to rotate about the stick axis, being rather firmly held in position by 'the struts 40. Therefore, no rotation preventing means have been shown in the drawing.
  • the locking devices 34 and 44 provided in the umbrella shown in FIGS. 1 to 9 may be combined into a single locking device which performs the functions of both, as shown in FIG. 10.
  • a locking pawl 52 is pivoted on sleeve 38 at 52 and, when the umbrella is in the open position shown in FIG. 2, its catch 53 engages an opening 54 in the sleeve 38 and an opening 55 in stick part 21 as well as in an opening 56 in stick part 21 and then locks all three parts 20, 21 and 38 relatively to each other.
  • the coil spring 24 utilized in the embodiments described above is replaced by a spring assembly located outside the stick.
  • the stick of the umbrella shown in FIG. l1 consists of two tubular parts 60 and 61, inner part 60 being shown in dotted lines in FIG. 11 and sectioned in FIG. 13. Parts 60 and 61 may be telescoped in the same manner as parts 20 and 21 in the umbrella according to FIGS. l to l0.
  • a crown 62 is fixed to the projecting upper end of part 60, ribs 63 being pivoted to the crown in the. usual way.
  • a tip 64 fixed to part 60 extends beyond the crown 62.
  • Tubular part 61 carries a handle 65.
  • a sleeve 66 is slidably mounted on the stick and is connected to each of the ribs 63 by means of struts 67, these struts being pivoted individually to the sleeve 66 at points designated 69.
  • the struts 67 are not just simple, rods, as will be described later.
  • the interior of the lower section of stick part 61 resembles that of stick part 21, shown in FIG. 5, except that the parts designated 28 and 30 are missing.
  • sleeve 33 is shown to carry a pawl 42 engaging openings 45 and 46, no such means are necessary in the embodiment shown in FIGS. 11 to 15.
  • a locking pawl 70 pivoted at '71 and acted upon by a leaf spring 72, which has a catch 73 engaging an opening 74 and projecting into an opening 75 just as in FIG. 5,r the opening 74 being provided in the stick part 60 and the opening 75 being provided in the lower stick part 61.
  • Pawl 70 also has a release knob 76 projecting through an opening in lower stick part 61.
  • the struts 67 pivotally connecting the ribs 63 to the sleeve 60 are designed to act as springs.
  • a brief description will sufce here, struts of the kind to be described now being well known to those skilled in the art.
  • the umbrella is equipped with a total of eight ribs; there are provided a total number of sixteen leaf springs 77 and 78, springs 77 differing from springs 78 only with respect to their arrangement and being otherwise identical therewith.
  • Each two adjacent springs 77, 78 form a pair representing one of the struts 67.
  • the leaf springs 77, 7S are just at pieces of steel of rectangular cross section, the longer sides of the rectangle lying approximately at right angles to the plane of the paper in FIG. 12.
  • Clamps 79 are provided for interconnecting the springs 77, 78 of each pair and thus assuring that the springs run parallel to each other from the respective pivot 69 on sleeve 66 to the point where the clamp 79 is xed to them.
  • the pivots 69 are offset angularly from the ribs 63 and that the inner section of each leaf-spring pair extends along a line bisecting the angle formed by the two adjacent ribs.
  • spring struts of the type described are a means for automatically closing the umbrella, which is basically equivalent to the spring 24 utilized in the embodiment illustrated in FIGS. l to 10.
  • the stick assembly is considerably simpliled lif the spring assembly is placed outside the stick, and it is, for eX- ample, thus possible to replace the pawl 42 shown in FIG. 5 by a locking means of simpler design ibut not less eiective.
  • FIG. 13 A type of spring catch suitable for an umbrella shown in FIG. l1 is illustrated in FIG. 13.
  • FIG. 13 shows an enlarged sectional view of the stick when extended, with sleeve 66 in its upper position, the umbrella thus having been opened in the conventional way without telescoping the stick.
  • a spring 81 stamped from ilat sheet steel, is disposed in the upper stick part 60 close to its lower end, spring 81 being prevented from longitudinal displacement by a stud 82 projecting into a hole 83 in part 6i).
  • the spring 81 has a catch 84 which, in the position shown in FIG. 13, projects through slots 85 and 86 in the walls of tubular stick parts 60 and 61.
  • Catch 84 has an-upper edge 87 running at right angles t the stick axis and forming a'face suitable for supporting the lower edge of the sleeve 66, as shown.
  • Catch 84 also has a rounded side face 88 projecting radially beyond the radius of sleeve V66 to an extent slightly exceeding the wall thickness of the lower and outer telescope member or stick part 61.
  • catch 84 When the umbrella is to be closed, catch 84 is depressed by hand so that the upper edge 87 releases the lower edge of the sleeve 66, the latter then moving down the stick and the roof ⁇ being closed.
  • Sleeve 66 now keeps Spring 81 in a position in which its rounded edge 88 contacts the inner surface of the sleeve 66. Owing to the dimensioning of the rounded edge 88, as speciiied above, catch 84 from now on will not prevent lower stick part 61 from moving up with reference to upper stick part 60. In fact, the catch 88 will then be moved further inward to an extent equaling the thickness of the wall of the outer stick part 61.
  • the umbrella after having ⁇ been closed by releasing spring 81 and letting sleeve 66 move down the stick, may be opened by telescoping parts 60 and 61 in the manner described above in connection with FIGS. 1 to 10. It may thereupon be closed automatically by pressing knob 76 and thereby releasing the outer stick part 61.
  • the umbrella having been closed either in the way just mentioned or by releasing spring 81 in the way explained above, may also be opened again by shifting sleeve 66 towards crown 62 until catch 84 of spring 81 locks, all parts then again being in the position shown in FIG. 13.
  • FIGS. l1 to 14 is not the only feasible way of providing spring action by means of a spring o-r springs disposed outside the stick.
  • the form of spring mechanism shown in FIG. 15 may for example be used instead.
  • all those parts of the umbrella which are not shown in FIG. l5 are identical with the corresponding parts in FIGS. 11 to 14.
