Definitions
- the present invention relates to umbrellas and particularly to an umbrella having a telescopic stick and three-section telescopic dome ribs.
- the present invention is an improvement over structure shown in applicants earlier applications. Since umbrellas of this type close to a very small package, it is somewhat difficult to open since all of the support structure and dome ribs are parallel to the axis of the stick and adjacent the stick, and especially since the support structure and the dome ribs are nested one within the other.
- a construction in accordance with the present invention includes an umbrella having a telescopic stick, a crown at one end of the stick, and dome ribs hinged to the crown.
- the dome ribs include three parts, each part telescopic in the other.
- a main runner is provided for sliding movement on the stick and an auxiliary runner slides between the crown and the main runner.
- the support structure is articulated to the auxiliary runner and the main runner to support the dome ribs in an open position.
- the support structure includes a stretcher member made up-oftwo articulated parts, with the end of one part hingedly connected to the dome ribs and the end of the other part'being hingedly connected to the auxiliary runner.
- a strutmember is hinged to the main runner and a link member is connected to the strut member and to the free end of the stretcher member part hinged to the dome ribs forming a quadrilateral structure with the stretcher member.
- Each of the parts forming the support structure are of U-shaped construction with the exception of the auxiliary link and one part is adapted to nest within the other when the umbrella is being closed.
- the quadrilateral structure has associated therewith a spring means normally forcing the quadrilateral structure towards an open position.
- the link member is provided with a hair-pin shaped extension which forms a bearing opening for the auxiliary link hinge and the free end of the hair-pin shaped auxiliary link bears against the stretcher member part hinged to the auxiliary runner when the umbrella is in a closed position, normally forcing it away from the auxiliary link.
- the spring means can be a hair-pin shaped element anchored at the hinge point between the stretcher member part hinged to the auxiliary runner and the strut member, or it can be a cutout portion of the strut curved in such a way so as to form the resilient spring member against the dome rib part hinged to the auxiliary runner.
- Another embodiment of the present invention would include a cut-out portion of the stretcher member curved to resiliently engage the stretcher member hinged to the auxiliary runner.
- Still a further embodiment of the present invention resides in a tension spring extended diagonally of the quadrilateral formed by the support structure between two diametrically-opposed hinge points.
- FIG. 1 is a schematic side elevational view of an umbrella in an open position
- FIG. 2 is a side elevation of an umbrella according to FIG. 1 in a closed position
- FIG. 3 is a fragmentary side elevation of the umbrella shown in FIG. 2 being open from a closed position;
- FIG. 4 is a fragmentary side elevation of the umbrella of FIG. 2 in anopen position
- FIGS. 5 through 9 are fragmentary views of different embodiments of a detail of the umbrella.
- FIG. 10 which is on the same sheet as FIG. 1, is a bottom plan view of the crown of the umbrella; and- FIG. 11, which is on the same sheet as FIG. 1, is a side elevation partly in cross section of the crown shown in FIG. 10.
- FIGS. 1, 2, 3 and 4 the three-stage umbrella is shown having a telescopic stick 1 comprising telescopic sections 2, 3 and 4.
- Stick section 4 has the smallest cross section and the free end thereof mounts a handle 5;
- the umbrella shown in the drawings is of the type generally known as a flat umbrella and, therefore, the handle 5 is of flattened cross section.
- the three-stage umbrella shown in the present embodiment has six dome ribs 6, each dome rib comprising'three sections, namely an inner section 6a, hinged to the crown 9; the central section 6b, telescopic in the section 6a; and an outer section 6c, telescopic within the central section 61;.
- Dome rib sections 60 and 6b are of U-shaped cross section, while outer section 6c is of steel wire circular cross section.
- Main runner 7 slides on the stick 1 and an auxiliary runner 8 slides on the stick 1 between the main runner 7 and the crown 9.
- the support structure is similarto' that described in US. Pat. No. 3,699,988 and includes articulated stretcher members 10 and 13 with the stretcher section hinged to the auxiliary runner 8, while it is articulated to the U-shaped stretcher section 13 at hinge point 19.
- the stretcher section 13 extends beyond the hinge point 19 to a hinge pin 20.
- a strut 11 is hinged to the main runner 7 at one end and to the stretcher section 10 intermediate thereof at the other end at the hinge point 18. Finally, an auxiliary link 12 extends between the hinge point 20 on the stretcher section 13 and a hinge point 21 is on the strut 11 spaced a short distance from the hinge point 18.
- the stretcher section 10 between the hinge points 19 and 18 as well as the link 12 and the stretcher section 13 between the hinge points 19 and 20 and the strut 11 between the hinge points 18 and 21 form a structural quadrilateral.
- the members 10, 11 and 13 are of U-shaped cross section and are arranged so that they can nest one within the other as shown in FIG. 2 when the umbrella is in a closed position.
- the auxiliary link 12 having an intermediate bend 48 nests within the U-shaped strut 11 which in turn nests within the U-shaped stretcher section 10 which itself nests within the stretcher section 13.
- the quadrilateral structure or parallelogram is identified by the letter V.
- the support structure is attached to the dome ribs 6 by means of the geats 14.
- a hinge pin is mounted within the geats l4 and the free end of the stretcher section 13 is hinged to the pin 15.
- the outer dome rib section 6c is also connected to the hinge pin 15 and, therefore, as the umbrella is being opened, stretcher section 13 pushes the outer section of the dome rib 6c outwardly, pulling with it the central section 6b.
- the articulated quadrilateral V formed by the above-mentioned hinge points 18, 19, and 21 is spring loaded'in accordance with the invention by a spring F in the direction of arrow x.
- the spring F is formed by a hair-pin shaped end 23 of the link 12 which extends over the hinge pin 21 and forms a bearing opening 22 over the pin 21.
- the extended end 23 is curved and enters the U-shaped stretcher section 10 resting against the web 24 thereof and is supported laterally by the legs 25 of this stretcher section 10.
- the spring F that is, the extended end 23 of the link 12 engages against the web 24 and is compressed or is loaded such that when the dome ribs are released, for instance, by unfastening a small retainer band which is generally about the cover of the umbrella when it is closed, the force of the spring F tends to open up the quadrilateral V by pushing out the stretcher section 10 thereby pivoting the dome ribs 6 in direction x. Since the cover material ,on the dome ribs 6 spreads out with the dome ribs 6, the main runner 7 is thus exposed and the person handling the umbrella can easily grip the main runner 7 in order to fully open the umbrella.
- the umbrella frame has a locking system for locking the umbrella in an open position.
- the auxiliary runner 8 has a downwardly extending sleeve 26 concentric with the axis of the stick. This sleeve 26 passes through the opening in the main runner 7 and is provided with two longitudinal slots 27 and 28 which are axially aligned but spaced apart.
- a catch 29 is provided on the umbrella stick as shown in FIG. 1 which engages an abutting end of slot 27 of the sleeve 26 as the runner 7 is pushed upwardly. This retards the forward movement of the runner 8 temporarily, thus enabling the stretcher section 10 and the strut 11 to spread the dome ribs 6.
- the runner 7 including an upwardly extending sleeve 30 passes over the catch 29 thereby allowing the runner 8 to proceed towards the crown.
- the catch 29 further engages the slot 28 against the abutting edge 32, as shown in FIG. 4, to finally limit the forward movement of the runner 8 towards the crown and leaving a space between the crown and the runner 8.
- the main runner 7 is locked in an open position as the catch 33 in the main runner engages through a slot in the sleeve 26 and into a slot provided in the stick as known.
- FIGS. 5 through 9 show other embodiments of the structure V.
- FIG. 5 shows a situation wherein a cutout portion 35 is cut out of the strut 11 and suitably bent in a curved position. This portion 35 is cut out from the web 36 of the strut 11 and engages the web 24 of the stretcher section 10.
- the link 12 is'modified compared to that shown in FIGS. 1 to 4 and is substantially as described in applicant's previous applications and merely acts to form the fourth side of the structural quadrilateral or parallelogram.
- a hair-pin device 37 is clipped onto the hinge pin 18, with one leg of the hair-pin spring 37, that is, leg 38 urging against the web 36 of the strut 11, while the other curved leg 39 urges against the web 24 of the stretcher section 10.
- a helical tension spring 40 extending diagonally across the quadrilateral and attached at one end to the hinge pin 20 and at the other end to the hinge pin 18. This is diagonally across the so-called parallelogram and always urges the parallelogram to an open position.
- the spring F is a cut-out portion of the stretcher section 10 and is from the web 24.
- This leg 42 urges against the web 43 between the legs 44 of the stretcher section 13 and forces the stretcher sections apart since they are normally nested together in a closed position.
- FIG. 9 shows yet another embodiment which is a reverse of that shown in FIG. 8, that is, the spring F is a cut-out leg 46 of the stretcher section 13 and urges against the back 47 of the stretcher section 10.
- An umbrella having a telescopic stick, a crown at one end of the stick, and dome ribs hinged to the crown; said dome ribs including three parts, each telescopic one within the other and a main runner provided for sliding movement on the stick with an auxiliary runner slidable on the stick between the main runner and the crown; a support structure articulated to the auxiliary runner and the main runner to support the dome ribs in an open position; the support structure including a stretcher member made up of two articulated parts with the end of one parthingedly connected to the dome ribs and the end of the other part being hingedly connected to tha auxiliary runner; a strut member hinged to the main runner and to the stretcher member and a link member connected to the strut member and to the free end of the stretcher member part hinged to the dome ribs forming a quadrilateral structure with the stretcher member; the link having an extension beyond the hinge point with the dome rib section hinged to the auxiliary
