A further object is to provide means for locking the links in alinement with the staff sections when the umbrella is used in the ordinary manner, and means for preventing closing movement of said links when the stafi sections are adjusted to center the cover over the head of the user.

A still further object of the invention is generally to improve this class-of devices so as to increase their utility, durability and efficiency.

the parallel links; Fig. 3 is a similar view,

looking at the opposite side of the umbrella; Fig. 4 is an end elevation, showing the manner of lockin the links in open position; Fig. 5 is a etail perspective view of a portion of one of the links and spring through the inner catch or lock for holdin the links in closed position, the s ring catc or look being detached from the adjacent link in order to more clearly illustrate the construction thereof; Fig. 6 is a detail rspective view of the locking collar detac ed; F' 7 is a vertical sectionalview, artly in gevation, illustrating a modified orm of the invention.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0% the drawing by the same reference characters.

The improved stafi adjusting means'forming thesubject matter of the present invention may be applied to umbrellas, parasols and the like, and by way of illustration is shown in connection with an umbrella of the ordinary construction, in which 5 designates the cover, the ribs 6 of which are con nected to the runner 7 by the usual braces 8.

The supporting rod or staff of the umbrella is preferably formed in two sections 9and 10 pivotally connected by parallel links 11 and 12, said links having their inner faces smooth and unobstructed. and their outer faces provided with longitudinal reinforcing ribs 13. The inner end of the upper stafl section is cut-away to form a reduced extension 14, to the free end of which is pivotally connected at 15, the adjacent end of the link 12, the other end of the link 12 being pivotally mounted at 16 on a similar extension 17 formed on the inner end of the lower staff section 10. One end of the mating link 11 is pivotally connected at 18 with the terminal of the extension 17, the other end of said matin link being pivotally connected at 19 with t e ex-- tension 14 on the upper staflf section, as best shown in Fi 2 of the drawings. One side of each sta section is provided with a flat face so as to permit the links 11 and 12 to be folded one upon the other to a position in alinement with the staff section when the umbrella is used in the usual manner.

Pivotally mounted at 20 on the reinforcing rib of the link 12, is a locking member, preferably in the form of a lever 21, one end of which is provided with a terminal lip 22 which enters a socket or depression 23 formed in an enlargement on the link 12, while the other end thereof is provided with a laterally extendin In 24 which projects at ace of the link 12 for engagement with a socket or depression 25 formed in the flat face of the mating link llwhe n the links are folded, thus to prevent 5 in'open position.

accidental opening movement of said links when the umbrella is not in use.

The lug2 t is normally and yieldably supported in position to enter the socket or depression 25 by means of a spring 26, one end of which is riveted or otherwise rigidly secured to the link12, while the other end thereof bears against the locking memberat the lug 24. Projecting laterally from. the flat face of the link 11, at one longitudinal edge thereof, is anear 27 adapted to enter a notch or recess 28 formed in the adjacent longitudinal edge of the mating link 12, thus to limit the closing movement of the links and assist in alining the latter with the staff sections.

As a means for locking the parallel links in open position, there is provided a sleeve 29, the upper end of which is formed with a cam face 30 adapted to enter a shallow recess 31 in the lower longitudinal edge of an extension 32 on the link 12, when said sleeve is rotated. The lower end of the sleeve 29 is provided with 9. depending stop lug 33 which engages stop shoulders 34 formed on a stationarycollar 35 secured to the lower staff section 10 for limiting the rotarymove- 'ment of said sleeve.

The sleeve 29is also provided with a vertically disposed slot 36 opening through the cam face 30, which slot, when the sleeve is rotated in one direction, registers with theextension 32 and permits the links to be moved to open position. Thus it will be seen that by rotating the sleeve 29 until the slot 36 therein registers with the extension 32 and subsequently depressing the locking member 21, and then moving the links laterally, said links will assume the position shown in Fig.2 of the drawings, and in which position they will be securely locked by rotating the sleeve 29, the cam face 30 of said sleeve enteringthe recess3l 'in the extension on the lower link 12, thus to prevent accidental closing movement: of the links.

A lug 36' is preferably formed on the ex-' tension 17 of the lower staff section 10. and adapted to enter a recess 37 in the adjacent link-12 to assist in sustaining the weight of the umbrella cover andits associated parts when-the links are moved to open position. Mounted'on the extension 14; of the upper staflf section 9, is a spring catch 38 adapted to engage the runner 7 and support the cover Under normal conditions, the parallel links ll-and 12 are disposed in alinement with the upper and lower by means of the sleeve 29, the solid portion of which covers the extension 32 on the lower link 12. In order to open the umbrella, it is merely necessary to slide the runner 7 longitudinally of the staff until the runner engages the catch 38 and in which position, it will be held from closing movement, the locking member 21 yielding to the ressure of the runner when the umbrella is opened so as not to form any obstruction to the passage of said runner. With the parts in this position, the umbrella may be used in the ordinary manner, that is to say, with .the usual rigid rod or staff. 1

When it is desired to move the handle of the stafl out of alinement with the upper staff section so as to permit a erson to stand directly beneath the center o the umbrella,

the sleeve 29 is' rotated in, order to present the slot 36 tothe extension 32 of the link 12, after which the catch 21 is depressed, which disengages the lug 24 from 'the socket 25 so that by exerting a slight pressure on the parallel links, said links may be moved to open position, as best shown in Fig. 2 of the drawings,-and in which position, they will be securely held by rotating the sleeve 29, as before stated.

It will here be notedthat as the links 11 and 12 are moved to open position, the inner pivoted end of the upper link 11 will bear against the lower edge of the runner 7 and move the latter out of engagement with the catch 38, and when'the links 11 and 12 are moved to folded or closed position in alinement with the staff sections-9 and 10, the runner 7 will bear against the catch 38 and partially'embrace the link 11, thus to assist in holding said links in alinement with said staff sections.

If desired, the upper catch 38 may be dispensed with, in WhlCh event, the runner 7 will be provided with a longitudinal slot 39 to accommodate the link 11, as best shown in Fig. 7 of the drawings, the construction and operation ofthe parts being otherwise similar to that shown in Figs. 1 and 2 of the drawings.
