' INVENTOR A 'm/z Sf/TFL LONGITUDINALLY COLLAPSIBLE UMBRELLA This application is a continuation application of US Ser. No. 829,971, filed June 3, 1969, now abandoned.

BACKGROUND OF INVENTION 1. Field of Invention An improved handle construction for longitudinally collapsible umbrellas for producing a flat rectangular package when collapsed, and more particularly an improved fan-shaped handle for promoting consistent operation and collapsing of the umbrella.

2. Description of Prior Art In prior art collapsible umbrellas having an upwardly opening receptacle for receiving dome rib tips, the bordering edges of the receptacle were in a single plane, this requiring considerable dexterity on the part of a person-attempting to collapse the umbrella since all dome rib tips had to be properly oriented and aligned before insertion into the handle receptacle; the simultaneous alignment of perhaps eight rib tips and maintaining them for simultaneous insertion in the handle gave rise to inconsistent operation, and general dissatisfaction, as well as excessive damage and wear on the cooperating parts.

OBJECTS OF THE INVENTION The general objects of the invention are to provide an improved handle for longitudinally collapsible umbrellas in which side walls generally project beyond end walls to form an open-sided dome-tip receiving receptacle; in which the handle receptacle accommodates a runner on which stretcher ribs are pivoted; in which the handle side walls diverge outwardly and include beveled camming edges; in which the handle side walls are arcuate so that dome rib tips are progressively engaged from the unbrella stick outwardly so the ribs are engaged and oriented in proper sequence; in which the handle provides a shape conveniently grasped in ones hand; and whereby the handle provides a configuration completely enclosing and concealing the umbrella runner.

BRIEF DESCRIPTION OF THE DRAWINGS These together with other and more specific objects and advantages will become apparent from a consideration of the following description of preferred embodiments of the invention when taken with the drawings forming a part of the description, in which:

FIG. 1 is a fragmentary, perspective view of the collapsed umbrella stowed in a carrying case;

FIG. 2 is an enlarged side elevational view of the collapsed umbrella and showing the handle, stick, stretcher ribs and dome ribs;

FIG. 3 is a side elevational view similar to FIG. 2, the near side wall being removed and the handle bottom wall being sectioned;

FIG. 4 is a vertical section taken generally on the plane of line 4-4 of FIG. 3;

FIG. 5 is a vertical section taken substantially on the plane of line 55 of FIG. 3;

FIG. 6 is a horizontal section taken substantially on the plane of line 6-6 of FIG. 3;

FIGS. 7, 8 and 9 are views similar to FIG. 5, showing various modifications; and

FIG. is a perspective view of the erected umbrella.

DESCRIPTION OF THE UMBRELLA Referring to FIG. 10, an erected umbrella of the eight dome rib type includes a central stick comprising decreasingly-diametered,

tubular elements

2, 3 and 4 extending respectively from a crown piece connected to element 2 and to which is hinged dome ribs 12 on which is suitably secured a flexible, foldable canopy. The tubular elements 2-4 are retained in extended relation by suitable locks; such as spring-urged detents 5 (not shown in detail), and the element 4 will telescope into element 3 and then both

elements

3 and 4 will telescope into element 2 when the umbrella is collapsed for storage, for example.

Reciprocably supported on the stick 1 is a runner 7 having

diametrical wings

8 and 9 to which are pivotally connected stretcher ribs 10 which are pivoted at 11 to a respective dome rib 12. Reciprocable above runner 7 is an auxiliary runner 13 to which are hinged on

wings

14 and 15 auxiliary stretcherribs l6 hinged to intermediate portions of ribs 10.

The umbrella crown,

runners

7 and 13 have a generally T-shape in elevation and the head serves to define the relatively flat packaged rectangular cross section of the collapsed umbrella, see FIGS. 3 and 6, for example.

Secured to the lower end of stick .1, i.e., connected to element 4 by means of an upwardly extending pin 33 integral with a narrow bottom 32, is a handle indicated generally at 6. As mentioned, the umbrella, when collapsed, assumes a generally flat rectangular shape, and the handle 6 aids to define this shape.

The handle when viewed in side elevation is generally fan-shaped having

sides

17 and 18 integral with the bottom 32 spaced outwardly from pin 33 (diverging upwardly slightly), and having upper, arcuate side margins 24, see FIG. 2, terminating in a slightly arcuate upper edge 27. The inner bordering edges of the

sides

17 and 18 are beveled at a merging into inwardly inclined surfaces b continuing to form outer margins of

receptacles

20 and 21 which will receive dome rib tips 12' see FIG. 3. The runner 7 in the collapsed-umbrella condition will have end edges 8' and 9 of the

respective wings

8 and 9 forming an orienting portion for the ribs 12, and the wings 11 will be received between opposed portions of the

walls

17 and 18, see FIGS. 3 and 6 The bottom wall 32 includes transverse, slightly raised

end walls

22 and 23 having beveled inner edges 0 at the upper edge which serve to cam the dome tips 12' into the

receptacles

20 and 21.

The bottom wall 32 has formed in upwardly extending relation, a well 30 into which is received the lower tubular sleeve portion 7 of the runner 7, see FIG. 3, and the sleeve portion 7 includes the usual laterallydisplaceable lock or latch 31.

The

walls

27 and 18 project at least out to the edge 19 of walls 22 and 23 (or therebeyond), and the

walls

17 and 18 are of sufficient height to enclose the wings of runner 7, as seen in FIG. 3, and since the

wings

8 and 9 are retained between

walls

17 and 18, the runner 7 cannot twist on stick I when the umbrella is collapsed. The arcuate margins 24 assist when inserting the collapsed umbrella into a rectangularly cross-sectioned carrying case 26, see FIG. 1, but have an additional orienting function with respect to dome tips 12.

Considering FIG. 5, the innermost tips 12' are shown by phantom lines as just engaging beveled edge a and the tips will be cammed toward surfaces b, and since the inner dome tips first engage the portion 27 closest to stick element 4, as the collapsing continues, the outermost tips 12' will then engage a more outward portion of edge 24, engaging the beveled surface which urges the tips inwardly, eventually striking beveled surface of

end walls

22 and 23. Thus, the tips are progressively or successively engaged by camming surfaces urging them into the

receptacles

20 and 21.

In FIG. 7, the same general handle arrangement 6 is provided, however, the walls 17' and 18 include only the upper beveled portion a which is considerably deeper or of greater width than bevels a of FIGS. 4 and 5. The end walls 22 and 23 (not shown) have bevels 0, however, the inner surfaces of walls 17' and 18 are generally parallel.

In FIG. 8, the walls 17" and 18" are relatively thin and converge downwardly to form a relatively wide mouth at the upper edge of the receptacle in which the dome tips 12 will be received and are guided by beveled surfaces a to inclined inner or lower camming surfaces b.

In FIG. 9, the walls 17" and 18" are relatively thin and upper

arcuate portions

28 and 29 which form arcuate camming surfaces a and the walls are of generally uniform thickness.

According to the described embodiments, an exceptionally flat umbrella is produced, and the dome rib tips are grouped or oriented into handle receptacles in an expeditious and consistent manner without excessive strain or umbrella damage. The rib tips are progressively oriented, i.e., they first engage surfaces a and subsequently engage surfaces b, or the equivalent. Further, the inner rib tips 12' engage the margin 27 adjacent the stick 1, and continued collapse of the umbrella results in the outer ribs engaging outer of lateral portions of margin 24, below the portions of edge 27 which were first engaged by the inner tips. The outer ribs will engage camming surfaces c of

end walls

22, 23, and the runner 7 will have its sleeve 7' engaged in well 30, and the

wings

7 and 8 are received or confined between

walls

17 and 18; the outer ends 8'9 of the wings serving to engage and orient the inner rib tips 12'see FIG. 6. The fan shape of the handle facilitates insertion into case 26, and the shape of the handle facilitates insertion into case 26, and the shape of the handle lends to comfortable and secure grasping in ones hand.

The umbrella dome or flexible covering is likewise received in the upwardly diverging, generally wide mouth of the handle, thus promoting a smooth uniform packaged umbrella without unsightly bulges.
