FIG. 6 is an end elevation of FIG. 5 i.e., looking from right to left at FIG. 5, for example; and

FIG. 7 is a top plan view of the handle element of FIG. 5, showing the tubular sleeve of 'the primary slide in phantom lines.

Q DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the drawing in detail, and first considering FIG. 1, an open, longitudinally collapsible umbrella U includes a stick 1, comprised of telescopically related, graduated

sections

2, 3 and 4 retained in extended relation by means of suitable, spring-urged detents 5; the sections 2-4 are preferably polygonal in cross section; hexagonal, for example.

Suitably secured to the upper end of stick section 2 is a rectangular headpiece 6 having a peripheral, skirt-groove receiving a pivot wire, and conventional, foldable or telescopic dome ribs 9 are pivotally mounted at one or the other of the narrow ends 7 or 8 or the headpiece.

An auxiliary slide is indicated generally at 13 and is an inverted T-shape in elevation; see FIG. 2 having diametrically opposed wings 12 to which are pivoted primary dome-struts l0, terminally pivoted or articulated at 11 to intermediate portions of the dome ribs 9. The auxiliary slide 13 includes an enlarged diameter sleeve portion 19 circumposed about the stick 2; the function of which to subsequently be described.

A primary slide is indicated generally at 14 and has pivotally connected to the wings l5 and 16 inner ends of tension ribs 14' which are terminally articulated to intermediate portions of the dome-struts 10. The sleeve 19 of the auxiliary slide 13 has an inwardly directed flange 19' at its upper end, and is engaged by one end of an axially disposed coil or compression spring 18, passing through the sleeve 19 and engaging the upper surface of the primary slide 14; the coil spring is circumposed about the umbrella stick, and normally loads the dome toward upward or an open position; and when the umbrella is collapsed, the spring is compressed, and until the ribs are substantially extended radially, the full force and effect of the compression or power spring is not exerted to open" the dome of the umbrella. Still further, the coil spring is of such a length and exerts a force to maintain the dome open" or extended. As is conventional, in order to close" the umbrella, the primary slide is pulled downwardly in the direction x as shown on FIG. 2; the spring 18 is compressed when the umbrella is fully opened and initially exerts a downward force when the umbrella is being closed.

As seen in FIG. 2, the primary slide includes a depending sleeve 17 having at one side an inwardly extending notch, groove or channel 22 which diverges from beneath wing 16 on a shallow arc terminating laterally above the bottom 17' of the sleeve 17. Formed at the diametrically opposed side of the sleeve 17 is a notch 23; beneath wing 15, and in which is disposed a pivotal latch-lever 21 (which is releasably engageable with cooperating portions on the umbrella stick as is conventional). The latch lever 21 is confined for pivotal movement in a slot or channel 20; see FIG. 3, and the outer cross section of the sleeve 17 is preferably polygonal, i.e., an elongated octagon, and having intersecting side edges 25, generally defining an elliptical configuration at the bottom of the sleeve 17 of slide 14; note end surfaces 27 are generally shorter in length than surfaces 26; the former lying along the minor axis y'-y' and surfaces 28 lying along the major axis y-y; as previously mentioned, the intersections of the sides 26-28 define a basic elliptical shape which is conveniently grasped when both opening and closing the umbrella.

Referring .to FIG. 4, the umbrella is shown in its collapsed or folded condition. The dome-ribs 9 will be conventional, either the foldable or telescopic types; for example, the foldable type being illustrated. Interrnediately of the ribs 9 are hinge-plate elements 31 defining tips disposed downwardly and generally at the lowermost portion of the folded or collapsed umbrella.

Suitably secured to the lower end of stick element 4, is a handle element 29 (preferably molded) which constitutes a component of the inventive contribution, functioning in cooperation with the major slide 14. The handle 29 includes diametrically opposed, upwardly opening recesses or compartments 32 which removably receive and orient tips 31. Note in FIG. 4 that sleeve 17 of the primary slide 14 depends to an upstanding mounting sleeve element 29' disposed between and generally defining the opposed recesses 32. The sleeve element receives the lower end of the stick element 4, being connected thereto by a transverse pin element 29", for example.

Referring to FIGS. 5 and 6, an alternate handle element 29 is shown, and reference numerals similar to those previously used will be used to identify correspondingly similar structure. The handle 29 includes a tubular hollow sleeve or tunnel 30 which has an inner bore cross section; see FIG. 6, defining an ellipse which correspondingly accommodates the polyangular exterior cross section of the sleeve 17. The sleeve of slide 14 substantially fills the tunnel bore and thus the tips or hinge plates 31 of the dome ribs cannot enter into the tunnel. Further, the external surface of the tunnel 30 is also polyangw lar defining lateral, angular surfaces 33 forming one side of the lateral chambers 32 for the dome-rib tips 31; orienting and locating these tips; and their rib, in generally spaced, parallel relation when the umbrella is folded and collapsed. The tunnel 30 includes upwardly diverging side surfaces 35 which engage the

wings

15, 16 of the primary slide 14, and guide the wings into proper orientation for subsequent opening of the umbrella; the surfaces 35 defining transverse grooves or notches 34 into which the

respective slide wings

15, 16 are removably received.

If desired, the notch 22 in the sleeve 17 may be provided with transverse serrations or ribs at 22' to facilitate gripping the slide 14 when raising or lowering the umbrella dome.

Rsum

From the structure disclosed, it is evident that the primary slide 14 includes opposed

notches

22, 23 which facilitate opening and closing of the umbrella; yet permitting the slide to be constructed as a relatively small and inconspicuous element; this is particularly desirable in the case of poweroperated umbrellas where the spring 18 exerts particularly great force at certain attitudes of opening, and when the spring must be compressed during closing to store energy for subsequent opening; compactness is important in collapsible umbrellas of the generally rectangular cross section when collapsed; further, it is important that the parts are properly oriented during both opening and closing to minimize inadvertent rubbing of ribs, dome and slides, so that wear on the parts is minimized; further, as the umbrella is opened and closed, the sleeve 17 is gripped at 22, 23; and fingers disposed in the latter notch 23 result in operation (opening) of the latch-lever 21; retaining the slide 14 for free reciprocable movement on the umbrella stick; additionally, the elliptical or polyangular configuration of sleeve 17 as well as tunnel 30 exteriorly facilitate gripping of the slide and handle, respectively; further, the fingers disposed below

wings

15, 17, when closing the umbrella, can absorb the considerable force imposed by spring 18 on slide 14 when the latch-lever 21 is released; additionally, the elliptical shape of the sleeve 17 and tunnel 30 conform generally to the rectangular shape of the umbrella crown and slides, the longer axis of the ellipse extending in the direction common to the longer side of the rectangle; and further, the wider bottom of the sleeve 17 (formed by notches 22, 23) conveniently and comfortably conform to the users hand making the umbrella comfortable to manipulate with minimum effort.
