Definitions

  • My invention relates' to improvements in folding umbrellas having telescoping stick and rib members and subsidiary braces or stretchers jointed with one of their ends to the main braces or stretchers and with their opposite ends-to an auxiliary runner which is freely vshiftable on the Istick and supports the frame in expanded position.
  • One of the objects of the improvements is to provide an umbrella which is simple in construction and reliablein operation, and in which more particularly the umbrella' may be readily opened, closed and collapsed.
  • Another object of the improvements is to provide an umbrella in which certain parts may be made from materials,
  • the said braking means may be in the form of a spring pressed lug projecting outwardlly from the stick and adapted to be pressed inwardly by the auxiliary runner being pushed upwardly.
  • Fig. 1 is a fragmentary elevation partly in section showing a folding umbrella with the stick 5 jointed with their ends respectively to the outer rib sections 4 and a main runner B, and supple- (Cl. 13S-23)sammlungy runner
  • Fig. 2c is a sectional plan view taken on the line 2c--2c of Fig. 2b,
  • Fig. 3 is a fragmentary sectional elevation on an enlarged scale showing another modification of the said braking'means
  • Figs. 4 to 6 are similar fragmentary elevations showing modifications of the said braking means, the figures showing the braking means in different positions, Figs. 7 and 8 are fragmentary sectional ele- 10I vations illustrating another modification of the said braking means, the said figures showing the parts indifferent positions,
  • Fig. J9 is a sectional plan view taken on the une 9 9 pf Fig. '1, 15
  • Figs. 10, 11 and 12 are fragmentary sectional elevations showing other modifications of the braking means
  • Fig. 13 is an elevation similar to thevone shown in Fig. 1 showing a modiiication ofthe umbrella with the stick members extended, the full lines showing the rib sections closed and the dotted lines showing the same opened,
  • Fig. 14 is an elevation showing the umbrella illustrated in Fig. 13 in collapsed position
  • Fig. 15 is a fragmentary sectional elevation on an enlarged scale showing the median part of the stick in extended position
  • Fig. 1 shows the stick members extended
  • the said means consist of a nose or lug Il which is in frictional engagement with the auxiliary runner I0, thus exerting braking action on the said runner when the main runner 6 is pushed upwardly, the said braking action beingsufllclent to prevent telescoplng of and to compel expansion of the frame of the umbrella.
  • said nose or lug is carried by a v spring located within the stick member I and it projects through a slot made in the wall of the said stick member. The braking action begins immediately when the main runner 6 is pushed upwardly.
  • Fig. 2 I have shown a modification in which the nose or lug Il' is located slightly above the auxiliary runner I0, so that the braking action begins immediately after the main runner has begun to move upwardly and before an unde sired telescoping of the rib sections together has begun.
  • Fig. 2a I have shown another modification in which the. braking action is exerted on the auxiliary runner by means of the spring pressed locking member I2 provided for holdingA the sticky members in extended position, the said locking member being passed through slots made in the stick members and into frictional engagement with the auxiliary runner I0.
  • the dimensions of the parts must be such that, with the stick extended and the umbrella in closed position, the auxiliary runner I0 is either in position for immediate engagement by the locking member I2 as is shown in the figure, or (analogously to the arrangement of Fig. 2) slightly below the said locking member.
  • the auxiliary runner is circular in cross-section, but I prefer to enlarge it at the side of the latch 1I on which the main runner is supported when the umbrella is expanded.
  • This construction is shown in Figs-'2b and 2c.
  • the runner is bulged outwardly at 92.
  • the outwardly bulged portion 92 passes over the latch 1I.
  • the runner I0 shown in the other figures may be similarly shaped.
  • the stick members are locked in extended position by means of locking devices which either are shifted by hand before the stick members are collapsed, or which, yieldingly held in advanced position, are forced aside by the collapsing movement of the stick members.
  • the last named construction is more simple, but in constructions now in use it-is not satisfactory, inasmuch as considerable. force must be exerted for collapsing the umbrella, and inasmuch as, further, the connection between the extended stick members is not sufficiently stable.
  • Another object of the improvements is to provide a locking device for the stick members which is more satisfactory in operation, and which connects the extended stick members to each other in a reliable way, and which can be readily released without requiring a special operation.
  • the invention consists in constructing the locking member so that it acts as a positive locking device when it is in fully advanced locking position, and which when shifted from locking position to an intermediate position of advance may by the powerful collapse of the stick members be shifted to fully withdrawn position'. Therefore the spring or other device for setting the locking member in locking position may be comparatively weak, so that the pressure needed' for collapsing the umbrella is small.
  • the locking device when the umbrella is expanded the ystick members are connected into a perfectly rigid stick which is able to take up the pressure of the wind, while when the umbrella is closed the locking device may be operated by comparatively small power.
  • the locking device then is suiiicient to hold the closed umbrella with the stick in extended position, but permits the stick members to be readily collapsed by hand.
  • the upper stick member Ia is the outer member of the telescoping stick, and it has the lower stick member 2a slidably mounted therein.
  • the locking device for the stick members is in the form 'of a curved spring IZI which is supported at I3 and I4 on the wall of the stick member 2a.
  • the said spring is formed at its upper end with a locking head which comprises upper and lower transverse faces I5 which are substantially perpendicular to the axis of the umbrella, and a bevelled portion I8, the said head being adapted for4 engagement with slits I6 and I1 made in the stick members Ia .and 2a.
  • the spring 'I2I has the function slightly to brake the aux-v iliary runner Ill when the umbrella is opened, as
  • One arm 2I of the said lever is formed with a locking nose or lug22 which engages inthe slits I6 and I1 of the stick members I and 2.
  • arm 23 has acoiled spring 2
  • the arm 23 of the lever 2I is not disposed perpendicularly to the axis of the stick. but at an acute angle thereto. Therefore, when the lever is turned from the position shown in Fig. 4 into those shown in Figs. v5 and 6, the length a: of the lever through which the spring 26 acts on the lever 2i is successively reduced, as is indicated in Figs. 4 tov 6.
  • the lever 20 providing the locking nose or lug 22 is not made perpendicular to the axis of the stickbut inclined relatively uthereto.
  • the security of the lock is not thereby diminishedfbut the pressure of the retracted lever on the inner wall of the stick member 2 is reduced, because the length of the lever 20 acting on the said wall is large.
  • the said lever 20 is inclined at an acuteangle to the direction of the movement of the outer stick member.
  • My improved construction of the locking device shown in Figs. 4 to 6 is particularly valuable in such ⁇ constructions in which the inward'movement of the lever 20 is started by the auxiliary runner I0 being passed over the same. In this case the highest resistance needed for forcing the nose inwardly from the position shown in Fig. 4
  • the lever 20 has the additionalfunction of lexerting braking action on the auxiliary runner I0, as has been described with reference to Figs. 1 to 3.
  • the upper stickmember I is located within the lower stick member 2, and in 4this'respect the construction.is similar to the one illustrated 'in Fig. 1.
  • a separate lever 21 is provided for exerting braking action on the auxiliary runner, while the lever 20I merely has the function' to lockv the stick members in extended position.
  • the lever 20I is similar in construction to the one described withl reference to Figs, 4 to 6, and the same reference characters have beenused to indicate corresponding parts. Ihe lever 21 is mounted within the stick member I on a pivot bolt 20.
  • the inner ends of the arms 23 and 2.5i ⁇ of thev levers 20I and 21 are connected with each other by a spring 30 tending to turn the said levers outwardly.
  • the lever 21 is provided with a rounded arm 32 projecting through a slit made in the stick member I and into position for braking engagement with the auxiliary runner I0, a nose 3i being provided for limiting'the outward movement of the arm 32.
  • the locking nose 22 of the lever 20I is' shaped so that it is pressed inwardly when the stick' members ⁇ I and k2 are telescoped together without requiring preliminary operation.
  • the moment exerted by the spring 30 is reduced as the lever 20I is pressed v inwardly, as has been indicated by the letter fc, so that in the position ofthe parts shown in Fig. 8 the friction of the lever 20I at 26 on the inner wall of the Lstick member 2 is small, the said friction being further reduced by the inclined position ofthe arm 2i.
  • the pivot bolts I9 and 28 of the levers 20I and 21 are fixed to sheet metal brackets 33 formed at their ends with enlarged portions 34 having a length substantially equal to the inner diameter of the stick member I. These. sheet metal brackets are inserted into the stick member and iired in position by means of va rivet 35.
  • de scribedwith reference to Figs. 4 to 9 permit the manufacture of the stick members from light metal, because the friction of the said levers sliding on the wall of the stick members is small.
  • the wear of the stick member 2 Aby the levers 20 and 20I sliding thereon may be further reduced by making the said stick member from comparatively tough metal, such for example as steel or brass, while the other parts of the stick, and more particularly the stick member I is made from light metal.
  • 'Ihis is particularly useful when the levers 20 and 20I and the springs attached thereto are not constructed so that the moment exerted by the-spring is reduced when the said levers are pushed inwardly.
  • 'I'he stick members Ib and 2b are made from light metal, and the bottom end 44 of the stick member ib is reinforced by means of a sleeve 45 made from steel and held in position by means of the shoulder 43 provided between the portion 44 and the body of the stick member Ib, and an inwardly pressed ridge 46.
  • 'I'he said sleeve may have a very thin wall, so that it does not increase the diameter of the stick member Ib.
  • 'I'he sleeve is formed with a slit 48 corresponding to the slit 41 of the portion 44.
  • the stick members are telescoped inwardly, and thereby the lever 39 recedes into the stick.
  • the sleeve 45 is made from hard material, so that it is capable of taking u ⁇ p the pressure of the lever 39 .without being deformed thereby. Therefore the stick members themselves may be made from any desired material, because they are not subject to wear by the pressure of the lever 39, and the said members may be made from material which is safe as against corrosion.
  • the reinforcement of the stick member by means, of a sleeve or ring is particularly reliable, because the force exerted by the lever is directed outwardly, and the sleeve is not subject to deformation by such outward pressure. Further, the pressure is distributed from the said sleeve over a large surface of the stick member.
  • a slit 48 is provided, I wish it to be understood that my invention is not limited to this feature, and that the reinforcing sleeve 45 may be disposed so that the lever 39 engages the lower margin thereof.
  • Fig. 11 The modification shown in Fig. 11 is similar to the one described with reference to Fig. 10, and the same reference characters have been used to indicate corresponding parts.
  • the bottomV end of the outer stick member Ic has the same diameter all through its length, andit is formed at a part remote from its bottom. end with an inwardly pressed circumferential portion 5
  • is fitted internally of the stick member Ic and between the portion 5
  • is used.' not only for locking the stick members, but it also limits the outward movement of the telescoping members, and therefore it is subject to slight jars.
  • the upper stick member Id is reinforced by an outer steel sleeve 52 fixed in position on the reduced end 44 of the outer stick member Id.
  • a positive locking device has been shown in Fig. 12.
  • the said positive locking device consists of a spring'53 which is located limited by an inwardly pressed ridge 55 made in the wall of the outer stick member Id and the enlarged top vend 56 of the inner stick member.
  • the spring engages not only the steel ring 45, 45
  • the pressure on the steel ring is somewhat reduced, -while the strain on the stick member is not very high. Therefore the wall of the ring may be comparatively thin.
  • Figs; 13 to 16 I have shown a modification in which all or a part of the inventions described with reference to Figs. 1 to 12 are embodied, and which in addition shows other improvements.
  • the umbrella com prises two telescoping stick members 51 and 58 which are hexagonal in cross-section, and in which the stick members are adapted to be locked in extended position by a latch 59 which is similar in construction tothe locking levers 20, 20
  • the top part of the'lower or outer stick member 58 near the latch 13 may likewise be reinforced internally or externally, by a sleeve such as the sleeves 45, 45
  • the stick member 51 carries a crown 60 to which the inner rib sections 6
  • the expanded frame is supported by means of main braces 63 which are connected at 64 to the outer rib sections 62, and by means of auxiliary braces 65 which are jointed at 66 to the main braces andat 61 to an auxiliary runner 68.
  • the main braces 63 are jointed to the main runner 69 which is locked in position by means of springs vany braking action is prevented.
  • Fig.,1 ⁇ 3 shows (in full lines) the umbrella in the closed position' and with the stick members extended.
  • the auxiliary runner 68 is located on the lower stick member58.
  • the stick member 58 passes over .the upper stick member 51, the stick lmember 58 and the auxiliary runner 68 moving simultaneously in a direction towards the crown ⁇ 60. Since the .auxiliary runner 68 is located on the stick member 58 the upper edge 12 of the stick member engages the spring 1l before the runner 68 can come to engagement therewith. Therefore the spring 1I is forced into the stick member 51 by the stick member 58, and has no retarding action on the auxiliary runner 68.v
  • the invention is not limited to the construction shown in Fig. 13 in which the auxiliary runner is placed on the lower stick member 58.
  • the retarding action on the auxiliary runner is particularly objectionable when the stick members are being extended, and to avoid this it is suiicient that the auxiliary runner 68 be located on the outer stick member 58 when the umbrella is in collapsed position as shown in Fig. 14, and that it does not leave this position on the outer stick member before the spring 1i has been released from the stick member 5B.
  • the main runner 69 consists of an elongated tubular body which is formed with a slit through which the latch 18 passes outwardly when the stick members have been extended, as is shown in Fig. 13.
  • the said tubular member forming the main runner is located within the hollow handle 13, where it presses the spring 10 inwardly, as is shown in Fig. 14.
  • the runner 69 -is elongatedat 16 so far that also in the collapsed umbrella the spring 10 is located within the said tubular member, ythe upper margin of the said tubular member being always located above the spring.
  • the main runner may be used'for supporting the subsidiary runner 68 when the umbrella is in open position.
  • the upper margin 11 of the tubular extension 16 bears on the bottom side of the auxiliary runner and provides, a reliable support therefor holding the same in centered position.
  • the same result may be obtained by ⁇ Aproviding the auxiliary runner at its bottom end with a tubular extension.
  • the dimensions of the runners and other 5 parts of the frame of the umbrella are properly selected, such an extension of one of the runners may 4be dispensed with.
  • the dimensions of the parts are such that when the umbrella is open the main 10 runner provides a support for the auxiliary runner, which is held betweenthe said main runner and the crown of the umbrella, as is shown in Fig. l in dotted lines.
  • the auxiliary runner engaging the crown 15 ' provides a limit for the upward movement of the main runner.
  • the spring latch 59 takes the form of a lever 13 supported within the stick at 18, the inner arm of the said lever having a 20 coiled spring attached thereto and the spring being anchored at 80.
  • the nose 59 passes through aAslit 82 of the inner stick member, and when the stick of the umbrella is extended, it engages in a corresponding slit 83 of the outer-stick member, so that the stick members are locked as against axial movement in either direction.
  • the slit 82 is located in an enlarged portion 84 of the inner stick member 51a by means of which the stick member is guided within the outer stick member 58a.
  • the guide is further improvedby having the margin 85 of the stick member 58a bent inwardly.
  • the nose 59 locks the stick members not only as against collapsing, but it also limits the out- 35 ward movement of the stick members before the enlarged portion 86 engages the contracted por ⁇ tion 85. Therefore the said portions are spaced from each other when the stick is in extended position, and thereby wedging lof thevparts is 40 prevented.
  • the braking devices such as the lugs or springs Il, i2, 20, etc., are operative only at the beginning of the upward movement of the auxiliary runner, and 45 thereafter the said runner has unimpeded movement on the stick so that the umbrella caribe easily opened and closed.
