Definitions

  • a latching device is located at the handle and movable within the space for locking the spherical knobs received therein, and a control device located inside the stick and operatively connected with the latching device. The control device is actuable for releasing the latching device into locking condition only when the knobs are received in the space.
  • My invention relates to collapsible umbrella of the type having roof-supporting ribs formed of three telescoping members, a corresponding telescopic, triblejointed umbrella stick, a main slider mounted on the stick and slidable therealong, a plurality of struts respectively having one end thereof articulatingly connected to the inner end of the middle roof-supporting rib members yand the other end thereof to the main slider, respective locking members between the middle and the outer roofsupporting rib members, a handle formed with an annular groove for receiving therein spherical knob members located at the free end of the outer roof-supporting ribs, and a displaceable latch member which, in latching position thereof, latches the spherical knobs in the handle.
  • the roof-supporting rib members simultaneously become excessively bent and, under certain circumstances undergo changes in shape due to having exceeded the elastic limit of the material, i.e., metal, for example, of which they are made. Such deformations of the roof-supporting rib members are most undesirable because the rib members are unable or are able only with great difficulty to be telescoped.
  • a latching member for locking the spherical knob members in the handle groove is operatively connected with a control member mounted within the stick of the umbrella.
  • the control member retains the locking member in nonlocking condition when the umbrella frame is not fully collapsed, and is actuable from a location at the middle portion of the stick for releasing the latching member to lock the spherical head members in the annular groove only after the spherical head members are actually received in the annular groove.
  • control member operatively connected between the latching member for the spherical knob members, which is mounted on the umbrella handle, and the middle joint of the umbrella stick can have dilerent constructions.
  • the control member comprises a push-pull rod movable between limiting positions determined by resilient stop means.
  • the push-pull rod is mova-ble out of one limiting position thereof by engagement of the end of the middle joint of the stick facing the umbrella handle with the resilient stop means, and being movable out of the other limiting position thereof by the insertion of a nosepiece, that is spring-mounted on the push-pull rod, into a recess formed in the wall of the hollow middle joint of the stick.
  • the latching member comprises a spring-biased disc displaoeable in the direction of the axis of the umbrella stick.
  • the dise is coupled by a plurality of balls with the push-pull rod, the balls being disposed between oppositely inclined conical surfaces formed on the push-pull rod on the one hand and on the latching member on the other hand.
  • FIG. 1 is a longitudinal sectional View of an umbrella frame constructed according to the invention, shown in fully extended condition of the stick thereof;
  • FIGS. 2 to 4 are views similar to FIG. 1 showing the stick in progressively shortened or telescoped phases thereof;
  • FIG. 5 is a longitudinal view of part of the umbrella frame in the extended condition of FIG. 1 showing two roof-supporting ribs in crossed condition;
  • FIG. 6 is a longitudinal View of the umbrella frame corresponding to the fully shortened condition of the stick shown in FIG. 4;
  • FIG. 7 is a partial cross sectional view taken along the line VII- VII in FIG. 5;
  • FIG. 8 is a partial cross sectional view taken along the line VIII-VIII in FIG. 6;
  • FIG. 9 is an enlarged longitudinal sectional view of part of the umbrella frame corresponding to the fully extended condition of the frame substantially as shown in FIG. 1 but with the struts thereof omitted;
  • FIG. 10 is a view corresponding to FIG. 9, however showing the frame in completely shortened or collapsed condition
  • FIG. 11 is an enlarged portion of the umbrella frame shown in FIG. 9 and identified by the reference character E therein;
  • FIG. l2 is another view corresponding to that of FIG. l1 showing the push rod within the stick located in another position.
  • FIGS. l to 4 of the drawing there is shown a stick of an umbrella frame formed of three telescopically slidable hollow joints 1, 2 and 3, of which the joint 3 is slidable in the joint 2, and the latter in the joint 1.
  • the stick joint 1 carries an umbrella crown 4 at the free end thereof, and the stick joint 3 has a handle 5 at the free end thereof, Roof-supporting ribs generally bearing the reference numeral 7, are pivotally connected at one end thereof -to the crown 4 by hinges 6 and are provided at the other end thereof with respective spherical knob members 8 (so-called points).
  • the roof-supporting ribs are formed, like the stick 1, 2, 3, of three telescopically collapsible portions, namely an inner portion 9, a middle portion 10 and an outer portion 11.
  • the inner ends of the middle portions 10 of which only an eye 12 is visible in FIG. l, are pivotally connected by a respective strut 13, the so-called main strut, to a slider 14, the socalled main slider, mounted on and displaceable along the stick 1, 2, 3.
  • the main slider 14 is held stationary by a suitable locking mechanism in the position shown in FIG. 1, and can also be locked in the vicinity of the umbrella crown 4 at the stick when the umbrella frame is open. Suitable locking or latching mechanism-s for this purpose are known and, in the interest of avoiding unnecessary complexity, are not shown in the drawings.
  • Each main strut 13 is hingedly connected with the auxiliary slider 15 by an auxiliary strut 16, which is connected by a joint 17 to the main strut 13 associated therewith.
  • the middle roof-supporting rib portion 10 and the outer roof-supporting rib portion 11 of each roofsupporting rib can be locked relative to one another in the extended condition thereof.
  • Locking devices for this purpose are likewise known and are therefore not shown in detail in the drawings.
  • the locking device is automatically snapped into locking position.
  • the middle rib portion 10 and the outer roof-supporting rib portion 11 of each roof condition while a relative sliding is effected between the inner rib portion 9 and the middle rib portion 10.
  • Two spring-mounted nosepieces 20 and 21 serve for mutually locking the stick joints 1, 2 and 3.
  • the nosepiece 20 interlocks the stick joints 1 and 2 and is formed on an arm 22, as shown in FIG. 9, which is subjected to the biasing action of a hairpin-shaped spring 23.
  • the arm 22 and the spring 23 are mounted in a bushing 24 which is fastened by a pin 2S to the middle portion 2 of the stick at the upper end thereof as shown in FIG. 9.
  • the nosepiece 20 In the locking position of FIGS. l to 3 and 9, the nosepiece 20 extends through registered slots or recesses 26 and 27 formed respectively in the stick joints 1 and 2.
  • the edge 28 of the nosepiece 20 is so shaped that the nosepiece 20 recedes into the interior of the hollow stick when the joints of the stick are telescopically collapsed by applying inwardly directed forces acting on the crown 4 and the handle 5 of the stick. In this inward direction, the locking action of the nosepiece 20 is thus only forcelocking and not form-locking. When the forces are applied in the opposite direction, i.e., when the stick is being extended, an edge 29 of the nosepiece 20 prevents the stick joints from separating from one another.
  • the nosepiece 21 serves for interlocking the stick joints 2 and 3 and is secured to a leaf spring 29a having an end which is anchored in a recess 30 formed in the Wall of the stick joint 3 and is thereby prevented from axial displacement.
  • the other end 31 of the leaf spring 29a abuts the resilient push-pull rod 32 which forms part of a control member 33, the purpose of which will be described more fully hereinafter.
  • the nosepiece 21 extends through two slots or recesses 34 and 34a formed respectively in the stick joints 2 and 3 in the interlocking position thereof as shown in FIG. 9.
  • the edge 35 of the nosepiece 21 is so shaped that the interlocking of the stick joints 2 and 3 is effected by form-locking or by force in both directions when the umbrella frame is extended. If the umbrella frame is therefore telescopically collapsed by applying pressure at both ends of the stick, then only the nosepiece 20, which interlocks the joints 1 and 2 solely by force-locking, yields initially, while the nosepiece 21 remains in the locking position shown in FIG. 9. The result thereof is that, when being telescopically collapsed, only the stick joints 1 and 2 are initially slidable relative to one another, while no relative displacement occurs between the stick joints 2 and 3. During the further course of collapsing the stick, the lower edge 36 of the stick joint 1, as shown in FIG.
  • the handle 5 is provided with an annular space or groove 36 on the side thereof facing the umbrella crown 4, which serves for receiving the spherical knob members 8 respectively located at the free ends of the roof-supporting ribs of the umbrella.
  • an opening 37 having ⁇ a diameter which is somewhat smaller than the diameter of the annular space 36, due to the shoulder 38 provided on the handle 5.
  • a latching member 39 is axially displaceably mounted on the handle 5 and is formed with a flange 40 which, in the locking position shown in FIG. 10, extends into the annular space 36.
  • the latching member 39 is subjected to the action of a helical spring 41 which continuously biases it and tends to move it into the locking position shown in FIG. 10.
  • the undesired crossing shown in FIGS. 5 and 7 can be prevented, however, when the umbrella is collapsed into the position shown in FIGS. 6 and 8 by the fact that the stiffer middle and inner rib portions 9 and 10 again straighten out the outer rib portions 11 when the umbrella is being collapsed and consequently assume the position shown in FIGS. 6 and 8.
  • This is possible, however, only if the spherical knobs 8a and 8b at the ends of the ribs can be arranged without hindrance within the annular space 36 of the handle 5 because of the suitable width c available within the annular space 36.
  • the nal position assumed by the ribs is that shown in FIG. 6.
  • the latching member 39 is controlled by the aforedescribed control member 33 comprising a plug 42 which is displaceably mounted within the hollow stick joint 3 and is connected to the resilient push-pull rod 32.
  • This control member 33 is so formed that when it is moved from the position shown in FIG. l0 into the position shown in FIG. 9, i.e., in the direction toward the umbrella crown 4, the latching member 39 is actually moved in the opposite direction, i.e., in the direction toward the end of the handle 5.
  • the plug 42 is provided with a conical recess 43 having a conical surface 44 which, in the position thereof shown in FIG. 10, serves for receiving a plurality of spheres or balls 45 therein.
  • the latching member 39 is provided with a corresponding conical recess 46 having a conical surface 47 which is, however, inclined in an opposite direction to the conical surface 44.
  • the balls 45 are received in the recess 46 when the latching member 39 is located in the non-locking position shown in FIG. 9.
  • the control member 33 With the aid of the balls 45 prevents the locking member 39, which is subjected to the biasing action of the spring 41, from passing into the locking position. Only when the control member 33 is displaced into the position shown in FIG. 10, are the balls 45 able to roll into the recess 43 in which they free the latching member 39 so that it can be shifted under the biasing action of the spring 41 into the locking position shown in FIG. 10. For this purpose, a displacement of the control member 33 in a direction toward the handle of the stick is required. If, contrariwise, the control member 33 is displaced from the position shown in FIG. 10 in a direction toward the umbrella crown 4, the conical surface 44 forces the balls 45 outwardly, and the latter in turn press the conical surface 47 and the latching member 39 therewith into the position shown in FIG. 9.
  • the control member 33 by means of the push-pull rod 32, is displaced through the middle stick portion 2 in both axial directions. Both positions, which can be assumed by the control member 33 as shown in FIGS. 9 and 10, are determined by an abutment nosepiece 48 which is secured to the rod 32 and is always received in a slot or recess 49 formed in the stick joint 3.
  • the recess 49 serves as a stop member and has an axial length equal to that of the path which is to be traveled by the latching member 39 as it transfers from the position of FIG. 9 into that of FIG. 10.
  • the control member 33 is force-lockingly secured by a nosepiece 50 which engages a springy bendable peak portion 51 formed in the upper end of the leaf spring 29a.
  • the control member 33 is transferred from the position shown in FIG. 9 into that shown in FIG. l0 by a pin 53 extending from the bushing 24 when the pin 53, near the end of the second phase of the telescopic collapse of the umbrella frame, engages the nosepiece 50. Accordingly, the spherical knobs of the roof-supporting ribs, which have rearranged themselves while being telescopically collapsed and have been inserted in the annular space 36,
  • the nosepiece 48 Toward the end of the extension of the joints 2 and 3, the nosepiece 48 becomes inserted into a recess 54 of the stick joint 2. If the stick joints 2 and 3 are not yet fully extended, that is to a point at which the nosepiece 21 is inserted into its respective recess, then, due to the insertion of the nosepiece 48 into the recess 54 according to FIGS. 2 and 12, the further displacement of the resilient pushpull rod 32 and the plug 42 is interrupted. By further displacement of the stick joint 3 to its end position until the nosepiece 21 is inserted into the recess 34, the nosepiece 50 slides over the peak portion 51 of the leaf spring 29a, whereby through the push-pull rod 32, the latching member 39 is transferred into its free position.
  • the nosepiece 48 is raised out of the recess 54 over the inclined surface 55, due to an edge 56 which borders the upper end of the slot or recess 49, which serves as a stop member according to FIG. 12, so that the stick joint 3 is further displaced into its limit position.
  • Collapsible umbrella comprising a substantially hollow stick formed of three telescoping portions, a plurailty of roof-supporting ribs respectively formed of an inner, a middle and an outer portion telescoping one another, said ribs being hingedly connected at the free end of said inner rib portions to one end of said stick, said outer rib portions having respective spherical knob members at the free ends thereof, a main runner mounted on said stick and displaceable along the axis of said stick, a plurality of main struts each pivotally linked with said main runner and with a respective middle portion of said roofsupporting ribs, a handle located at the other end of said stick and formed with an annular space for receiving said spherical knob members therein, in fully telescoped 'condition of said stick and said roof-supporting ribs, said annular space having -a given radial width at least equal to twice the diameter of said spherical knob members, latching means located at said handle and movable Within said annular
  • Collapsible umbrella according to claim 1 including means for locking the respective middle and outer rib portions relative to one another in extended condition thereof, rand further means operatively connecting said control member and said middle rib portions for maintaining said latching means in locking condition as said stick and roof-supporting ribs are being extended until said respective middle and outer rib portions are locked relative to one another by said locking means.
  • control means comprises a push-pull rod displace-l able within said hollow stick between a pair of limiting positions, resilient stop means for determining both limiting positions of said push-pull rod, said resilient stop means comprising a resilient nosepiece engageable by the end of said middle stick joint facing said handle for moving said push-pull rod out of one of said limiting positions thereof and conversely said resilient nosepiece being receivable in a recess formed in the wall of said middle stick joint for moving said push-pull rod out of the other of said limiting positions.
  • said latching means are displaceable in the axial direction of said stick and including spring means in said handle biasing said latching means and tending to maintain said latching means in locking condition, said latching means having a flange portion receivable in said annular space in the locking condition of said latching means, said latching means and Said control means having conical surfaces defining space means therebetween and ball means located within the space means between said conical surfaces and cooperating with said surfaces for coupling said latching means and said control means together so that movement of said control means in a given axial direction produces movement of said latching means in an opposite direction thereto.
