Abstract
A rib linkage system of the topless type comprises stretcher ribs 30 to connect the umbrella's runner 18 with each cover rib 25, support ribs 42 to connect the umbrella's ferrule 17 with each stretcher rib 30, and control links 52 to connect each support rib 42 with its associated cover rib 25. The connection of the support rib 42 with the stretcher rib 30 is by means of a split or bifurcated brace structure 57, 60 that enhances the stability of the linkage system when the umbrella is full opened. The control link 52, support rib 42, stretcher rib 30, and cover rib 25 all cooperate to define a generally parallelogram configuration beneath the stretcher rib when the umbrella is in between its full opened and full closed positions (Fig. 2), and to define a generally triangular configuration when the umbrella is full opened Fig. 1., again to enhance the stability of the linkage system when the umbrella is opened and also to permit the umbrella to collapse into a short and compact storage or full closed position (Fig.3). <IMAGE>
Description
SPECIFICATION
Umbrella rib linkage system
This invention relates to umbrellas. More particularly, this invention relates to an improved umbrella rib linkage system, and to an umbrella that incorporates that improved rib linkage system.
There are two basic types of umbrellas, namely, stick umbrellas and collapsible umbrellas. In a stick umbrella, the umbrella centrepost is of a single fixed length. In a collapsible umbrella, on the other hand, the umbrella centerpost is composed oftwo or more sections that can telescope one within the other in order to shorten the centerpost length and, thereby, shorten the umbrella itself, when it is in the collapsed or storage position. Collapsible umbrellas, have been well received in the market place in recent year, because they are so easy to store and to carry by their owners. A collapsible umbrella can be carried in a briefcase or handbag or the like so it is always available for use if the need arises, whereas a stick umbrella is normally only carried when it appears that its use will be necessary.
A rib linkage system for a collapsible umbrella must permit an overall umbrella length that is reasonably short in the storage or full closed position, relative to the full opened or use position, so the umbrella can be easily stored or carried wherever desired by the user.
There are a couple of different basic types of rib linkage systems by which a collapsible umbrella's cover can be erected and collapsed that meet this short length objective, one being of a simplerstructure and easierto operate, than the others. This one type of collapsible umbrella rib linkage system has seen significant success in the market place, and is known as a topless umbrella rib linkage system. The topless rib linkage system is particularly usefui and practical in connection with collapsible umbrellas. The topless umbrella rib linkage system incorporates a series of cover ribs that only partially support the umbrella's cover when it is open.The cover ribs extend radially inward from the outer periphery ofthe covertoward the centrepost, but they stop significantly short ofthe centrepost, e.g., they may only extend half the radial distance from the cover's outer periphery to the centerpost. Thus, the cover ribs are not directly connected to the umbrella's ferrule. This is contrary to other rib linkage systems in which the umbrella's cover ribs are directly connected to the umbrella's certerpost and do extend radially outward from the centerpost to the cover's periphery. One such topless rib linkage system that has been well received in the collapsible umbrella market place isthat illustrated in U.S. patent No. 3 467115.
Acollapsible umbrella must be relativelyshort when it is collapsed for storage, but it also must be of regular or usable size when it is open. In other words, it is desirable to maintain as large a radius as possible forthe umbrella'scoverwhen the umbrella isfull opened, while providing a rib linkage system that permits the centrepost and rib linkages, as well as the cover, to be retracted to a desirably short overall length when it is in a storage or full collapsed position.
But in meeting this overall objective, it also is necessarythatthe umbrella's rib linkage system be relatively strong so as to withstand wind forces to which the umbrella may be subjected during use. In this regard, it is necessary that the umbrella's rib linkage system be strong against wind induced forces generally parallel to the centerpost that might tend to collapse the rib linkages, as well as wind induced forces generally perpendicularto the centerpost that might tend to sway or bend the rib linkages.
In accordance with one aspect of the invention, an umbrella comprises a center post having a runner slidablethereon, a cover connected at its center to the centerpost, and a topless rib linkage having a cover rib to which the cover is connected, a stretcher rib connecting the runner and the cover rib, a support rib connecting the stretcher rib and the centerpost, and a control link connecting the support rib and the cover rib, the stretcher rib, cover rib, support rib and control link defining a profile opening of generally parallelogram configuration when the umbrella is between full opened and full closed positions, and defining a profile opening of a generally triangle configuration when the umbrella is in the full opened position.
In accordance with another aspect of the invention, an umbrella comprises a centerpost having a runner slidable thereon, a cover connected at its center to the centerpost, and a topless rib linkage having a cover rib to which the cover is connected, a stretcher rib connecting the runner and the cover rib, a support rib connecting the center post and the stretcher rib, and a control link connecting the support rib and the cover rib, the support rib being bifurcated at least at its outer end to provide parallel struts at the outer end, the support rib struts being positioned outboard ofthe control link and outboard ofthestretcher rib at the respective connections of the support rib with the control link, and of the support rib with the stretcher rib.
In accordance with yet another aspect of the
invention, an umbrella comprises a centerpost having a runner slidable thereon, a cover connected at its center to the centerpost, and a topless rib linkage
having a cover rib to which the cover is connected, a stretcher rib connecting the runner and the inner end of the cover rib at a location between the support rib's ends and also connected to the centerpost,the outer end of the support rib being of a generally dog leg configuration, and a control link connecting the outer end ofthe support rib with the cover rib at a location between the cover rib's ends, the control link being connected to the toe end ofthe support rib's dog leg outer end, thereby locating the control link beneath the stretcher rib when the umbrella is furl opened and held in an upright use position.
Such rib linkage systems have the stability and strength so asto permit practical use ofthe umbrella by the umbrella's owner, and further are structured to permit use in a collapsible umbrella that is of a relatively short length.
The umbrella rib linkage system includes a stretcher
rib that connects the umbrella's runner with each cover rib, and a support rib that connects the umbrella'sferrulewith each stretcher rib, and a control link that connects each support rib with its associated cover rib.
The connection of the support rib with the stretcher rib is preferably by means of a split or bifurcated brace structure that enhances the stability ofthe linkage system when the umbrella is full opened. The control link, support rib, stretcher rib, and cover rib all cooperate to define suitably a generally parallelogram configuration beneath the stretcher rib when the umbrella is in between its full opened and full closed positions, and to define a generallytriangularconfiguration when the umbrella is full opened, again to enhance the stability of the linkage system when the umbrella is opened and also to permit the umbrella to collapse into a shortand compactstorage orfull closed position.
The invention will now be described, by way of example, with referance to the accompanying drawings, in which:
Figure lisa side view of one embodiment of umbrella in accordancewiththe invention, the umbrella being shown in the full opened position,
Figure 2, is a side view similarto Figure 1 but showing the umbrella of Figure 1 in an intermediate open position,
Figure 3 is a side view similarto Figures 1 and 2 but showing the umbrella of Figures 1 and 2 in thefull closed position;
Figure 4 is a cross sectional view of the umbrella of
Figure 2,taken along iine4-4 of Figure 2, and
Figure 5 is a cross sectional view similar to Figure 4, but illustrating another embodiment of umbrella in accordance with the invention.
The umbrella shown in Figures 1 to 4 is collapsible into a storage position shown in Figure 3 and erectable into a use position shown in Figure 1. The umbrella basically includes a centerpost 10, a cover 11, and a series of eighttopless rib linkages 12. The centerpost 10 includes an upper section 14 and a lower section 15 telexcopable relative one to the other between collapsed (Figure 3) and erected (Figure 1 ) positions, same being held in the erected position by a first spring loaded latch 16 in accord with known umbrella practice. The umbrella cover 11 is supported byeightseparate rib linkages 12, all these linkages being identical one to the other. The rib topless linkages 12 interconnect with the umbrella's ferrule 17, and with the umbrella's runner 18.The umbrella's ferrule 17 is fixed to the top end ofthe centerpost, and the runner is movable orslidable along the centerpost for raising and lowering the cover 11. The runner 18 is held in an upper or umbrella full opened position by a second spring loaded latch 19 also in accord with known umbrella practice. A handle 20 isfixed tothe bottom end ofthe centerpost 10 so the umbrella can be easily held by the userwhen it is open.
Each topless rib linkage 12 includes a cover rib 25 to which the cover 11 is fixed at its outer periphery 26 as at 27, e.g., by tying with thread. The cover rib 25 extends radially inward toward the umbrella's centerpost 10, but is of length Lonly equal to about one-half the radius L' of oftheumbrella's cover so that the cover rib terminates as at its inner end 28 about midway between the cover's periphery 26 and the centerpost.
It is this cover rib 25 structure, which cover rib 25 is not connected to the umbrella's ferrule 17, that gives use to the "topless" reference in the characterization of a topless rib linkage system.
The topless rib linkage 12 also includes a stretcher rib 30 pivotally connected as at 31 at its inner end 32 to the runner 18, and pivotally connected as at 33 at its outer end 34to the cover rib 25. Note the stretcher rib 30 is generally linear from one end 32 to the other 34, and defines longitudinal axis 35 when the rib linkage 12 is relaxed as shown in Figure 3. A bracket 37 is mounted to the inner end 28 of the cover rib 25, the bracket being configured to establish a generally radially inward and downward directed dog leg atthe inner end 28 of that cover rib. It is at toe end 38 ofthe cover rib dog leg's foot 39 that the stretcher rib 30 is pivotally connected.As is apparent from Figure 1, therefore, the pivot connections 33 ofthe cover rib 25 with the stretcher rib 30 is spaced inward of the longitudinal axis 40 of that cover rib. Thus, and as particularly shown in Figure 1, the pivot connection 33 ofthe stretcher rib 30 with the cover rib 25 is spaced slightly inward of the cover 11 itself when the umbrella is full opened to minimize rubbing, and therby wear, of the cover at that point.
The rib linkage 1 2further includes a support rib 42 pivotally connected as at 43 at inner end 44to the ferrule 17, and pivotallyconnected as at45 intermedi- ate its inner and outer 46 ends to the stretcher rib 30.
The intermediate pivot connection 45 is established by ears 47 mounted to the stretcher rib 30 that locate that pivot connection 45 above and outboard of the stretcher rib 30, i.e., between the stretcher rib and the umbrella's cover 11 and above the longitudinal axis 35 of that stretcher rib. The outer end 46 of the support rib 42 is formed to establish a generally radially outward and upward directed dog leg configuration, the support rib's dog leg configuration being substantially a reverse image ofthe dog leg configuration provided on the inner end 28 ofthe cover rib 25. In otherwords, angle 49 at dog leg end 28 of the cover rib 25 is substantially the same as angle 50 at dog leg end 46 of the support rib 42.
The rib linkage 12 also includes a control link 52 pivotally connected as at 53 at its inner end 54to the support rib 42, and pivotallyconnected as at 55 at its outer end 56 to the cover rib 25. Note particularly that the former point connection 53 is therefore established between the support rib's longitudinal axis 57 and the cover rib's longitudinal axis 40 i.e., is not on the support rib's longitudinal axis. This, of course, is because ofthe radially outward directed dog leg configuration of the outer end 46 ofthe support rib 42.
Inwardly directed ears 58, that are part of bracket 37, are mounted to the cover rib 25 adjacent its inner end 28 to establish the pivot connection 55 of the control link 52 with the cover rib 25. The pivot connection 55 so defined is inwardly positioned relative to the longitudinal axis 40 ofthe cover rib 25. Note particularlythe linear axis 60 ofthefoot end 46 of the support rib 42 is generally coaxial with the linear axis 62 of the control link 52 when the umbrella isfull opened as shown in Figure 1, but not otherwise.
The configuration of the rib linkage 12, i.e., the stretcher rib 30, the support 42, the control link 52 and the cover rib 25, when the umbrella is in an intermediate open/close position is as shown in Figure 2, and when thethe umbrella sin afull opened position isas shown in Figure 1. In both ofthese positions, the control link 52 is oriented beneath the stretcher rib 30, i.e., the control link is underslung beneath the stretcher rib, so as to define a rib linkage profile opening 65 slung under or positioned beneath the stretcher rib when the umbrella is held vertically upright in a use position.When the umbrella rib linkage 12 is in the intermediate open/close position, this underslung opening 65 is of a generally parallelogram configuration as shown in Figure 2. On the other hand, when the umbrella rib linkage 12 is in the full opened position this underslung opening 65 is of a generally triangular configuration as shown in Figure 1.This parallelogram/triangle configuration change of the profile opening 65, it is believed, enhances the structural stability of the rib linkage 12 during use of the umbrella.And the fact that the control link 52 is underslung beneath the stretcher rib 30 in this rib linkage 12 permits the umbrella to be collapsed to a shorter length X, as shown in Figure 3, for easier storage in smaller spaces than would be the case if the control linkwas abovethe stretcher rib 30 (as is currently used in topless umbrella rib linkagescur- rently sold in the market place, and as shown in U.S.
patent no.3467 115). This parallelogram/triangle interrelationship ofthe rib linkage profile opening 65 defined bythe stretcher rib 30, support rib 42, control link 52, and cover rib 25, between the intermediate (Figure3) and full opened (Figure 1) positions ofthe umbrella, is made possible by virtue of the dog leg configuration ofthe support rib 42 at its outer end 46, and the factthatthe pivot connection 53 of the control link 52 with the support rib 42 is radially outward ofthe longitudinal axis 57 of that support rib.
The structural rigidity of the rib linkage 12, when the umbrella is full opened, is also enhanced by the structure ofthe support rib 42 at its outer end 46 and in that area where same is pivotally connected to the stretcher rib 30, see Figure 4 and 5. The stretcher rib 30, in cross section, is of a generally U-shaped configuration at the point 45 where it is pivotally connected with the support rib 42. The stretcher rib 30 provides two ears 47 that stand upwardly above the stretcher rib's longitudinal axis 35. The support rib 42, in preferred form as shown in Figure 4, is defined by a pair of struts 66,67 pivotal ly connected to the ferrule 17 in equally spaced radial slots 68 by wire 69, the struts being parallel one with the other.One 66 of each pair of struts is pivotally connected to one 47a of the stretcher rib's ears, and the other 67 ofthe struts is pivotally connected to the other47b of the stretcher rib's ears, same being connected by common pin 70.
Note the struts 66,67 of support rib 42 are located outboard of the stretcher rib 30 on opposite sides thereofto entrap the stretcher ribtherebetween. And further, note the toe end 46a on one 66 ofthe support struts is connected on one side ofthe control link 52, and the toe 46b ofthe other 67 of the support struts is connected on the other side of the control link. This bifurcated dog leg 57,60 structure ofthe support rib 42 at its outer end where it is connected to the stretcher rib 30 and to the control link 52 is also important relative to enhancing the structural stability of the rib linkage 12.This, topless rib linkage 12 stability is enhanced againstwind type forces that are exerted against the umbrella cover 11 during use of the umbrella, those forces being shown diagrammatically by phantom arrows 71A, 71 B disposed generally parallel to the centerpost 14 as well by phantom arrows 72, 73 generally perpendiculartothe centerpost.The point here is that the support rib 42 structure at its enterconnection 45 with the stretcher rib 30 as well as with the control link 52, in combination with the geometry of the support rib at its dog leg outer end 46 which provides th e pa the parallelogram/triangle configura- tion ofthe opening 65 defined by the rib linkage 12 in the intermediate (Figure2) and full opened (Figure 1 ) position ofthe umbrella, all cooperate to enhance the stability ofthattopless umbrella rib linkage.
An alternative embodiment ofthe support rib 42 is illustrated in Figure 5. The alternative embodiment of the support rib differs from the Figure 4 embodiment in thatthe alternative embodimentsupport rib 75 is of a single piece or unitary configuration. The alternative support rib 75 is of a generally U-shaped cross sectional configuration throughout its length except at its inner end 76 and at its outer end 77. At its inner end 76,the U-shaped support75 is pressed together as at 78 to provided a single pivot connection 79 at which the support rib is pivotally connected by wire 80 in a single slot 81 to the ferrule 17. At its outer end 77, however, the U-shaped support rib 75 is bifurcated as is the case with the support rib 42 shown in Figure 4.
This bifurcated end 77 defines opposite parallel struts 82, 83, each ofthe struts being of a dog leg configuration identicaltothe dog leg end 46 of support rib 42. As is the case with the Figure 4 embodiment, the dog leg sections 82, 83 so defined at the outer end 77 ofthe alternative support rib 75 are pivotally connected by pin 84 on the outboard sides of the stretcher rib 30, and on the outboard side of the end 54 ofthe control link 52. This alternative embodiment support rib 75 also improves the structural stability ofthe rib linkage 12 when the umbrella is in the full opened position.
