Application November 29, 1935, Serial No. 52,049

12 Claims.

This invention relates to umbrellas or parasols of the collap'sible type in which a marked reduction is effected in the overall length of the umbrella, when fcl'osed, so that it may be conveniently carried in thepocket, handbag or suitcase.

The subject matter of the present application is, in Lpart, a continuation 'of my prior application'for lpatentfierial No. 752,197, filed November19, 1:934, "and relates more particularly to the latch means, whereby the telescopically connected sections @of the umbrella staff are retained in telescoped or extended relation to each other.

-A more particular object of the invention resides in the provision of a yieldable latch element mounted within the inner staff section and .a pin mounted on the end of the outer stall section, and having means at its inner end adapted to coact with said latch element.

In one embodiment of the invention, the latch device may be provided with spaced parts for coacting engagement with spaced means on one of the staff sections, whereby said staff sections are retained in telescoped or extended relation to each other.

In another embodiment of my invention, the pin carried by the outer staff section may be manually moved to cooperate with the latch element and move the latter to released position, whereby the'inner staff section may be extended from the outer section.

It is a further general object of my invention to provide a latch means for the sectional umbrella staff which is simple, durable and inexpensive in its construction, as well as eflicient and reliable in practical operation.

With the above and other objects in view, the invention consists in the improved umbrella or .parasol, and in the form, construction and relative arrangement of its several parts as will be hereinafter, more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings, wherein I have illustrated several simple and practical embodiments of the invention and in which similar reference characters designate corresponding parts throughout the several views:

Fig. .1 is a fragmentary vertical section illustrating one embodiment of the invention, and

showing the umbrella open and ready for use.

Fig. 2 is a similar vertical section on an. enlarged scale-showing the umbrella closed and the staff sections in telescoped relation.

Fig. 3 is a vertical sectional view similar to mounted in the end of this sleeve, for a'purpose one of its ends to the member Fig. '1, illustrating a modifiedembodiment of the invention, and V Fig. 4 l is a sectional View corresponding to Fig. 2 of the modified form of the device.

Referring in detail to the drawings, the umbrella staff as herein shown, embodies upper and lower sections 5 and 6 respectively, of thin walled metal tubing. Preferably, the lower section '6 is telescoped within the upper section 5, suitable means being provided to limit the outward extension of the section 6 from the staff section 5. Upon the upper end of the outer staif section 5, a sleeve l is suitably fixed and a pin -8 is to be later explained. i

The usual runner 9 is vertically slidable on the staff section 6 and carries a latch element -*i to releasably engage at one of its ends in an opening in the wall of the staff section 5 'to retain said runner at the limit of its outward 2O movement. To the sleeve l and the runner 9, the parts of the umbrella frame are connected. This frame, herein "generally indicated at H,- has a covering of e1asticsheet material 12, suitably applied thereto. For a more particular description of this collapsible frame and its covering, reference maybe had to my pending application forpatent above referred to.

Within the staif section-6, a slotted or grooved member i3 is suitably fixed. As shown in Figs. 1 and 2 of the drawings, a latch member in the form of a bowed leaf spring M is connected at I3 and at its other free end is provided with an angularly .offset part it and adjacent thereto with the convex stud it for bearing engagement against the inner wall of the staff section 6. Intermediate of its ends, a lug i! is fixed to the latch element 9 to project outwardly through an opening it in the Wall of the staff section 6 when the'staff sections are in t'elescoped relation. This lug is received in a recess iii in the lower end of the wall of the stall section 5 to releasably hold the section 6 in its extended position and "Bis moved into the section 5 untilits end abuts against the end of the sleeve 11, the angular offset 15 at the free end of the'latch element l4 first engages the conical end 2| of the pin 8 and yieldably moves said latch element from its normal position until said end portion l5 of the latch element snaps over the shoulder 22 of said pin. The stud l6 bearing against the wall of the staff section 6 insures adequate tension of the spring to resist unintentional outward movement of said staif sections.

In opening the umbrella, the staff section 6 is first pulled outwardly, the end I 5 of the latch element M yielding in response to such pull and being disengaged from the shoulder 22 of the pin 8. At the limit of the outward movement of the staff section 6, the lug H on the latch element is projected outwardly into the recess l8 in the end of the staff section 5, thus preventing unintentional inward movement of the stafi section 6 and locking the staif sections against relative rotation.

In Figs. 3 and 4 of the drawings, I have shown a slightly modified form of the invention in which the member I3 is mounted in the staff section 6 at a point adjacent to its upper end. The latch element 23 is mounted in the slot or groove of the member I5 for pivotal movement upon the pin 24. In this case, said latch element is in the form of a lever (one end of which projects below the member l3 and has an angular locking finger 25 adapted to be projected outwardly through registering openings 26 and 21 respectively in the staff sections 5 and 6 by means of the spring 28 which is connected at one of its ends to the latch lever and has bearing engagement at its other end against the wall of the staff section 6. Preferably, this spring 28 in spaced relation to its point of attachment to the latch lever has bearing contact upon a stud 29 fixed to said lever, so that said spring will be properly tensioned when the lever is displaced from its normal position.

At its other end, the latch lever 23 is formed with an obliquely inclined lug 3!], with which the conical end 3| of pin 32 is adapted to coact. In this case, the pin 32 is carried by a separate cap member 33 threaded through the outer end of the sleeve 1 and which cap member also serves to clamp the central portion of the umbrella cover l2 against the said sleeve. The pin 32 extends through a recess in said cap member and is surrounded by the coil spring 34 which bears against the head of the pin and yieldably urges the same outwardly to its normal position.

In spaced relation to its lower end, the wall of the staff section 5, in this last described form of the device, is provided with an opening 35, with which the opening 26 of the staff section 5 is adapted to register when the latter section is extended outwardly to its limit from the section 5. The angular member 25 of the latch lever is then projected outwardly by the spring 28 through these registering openings, thereby locking the two staff sections against any longitudinal or rotative movement.

In closing the umbrella, the end 25 of the latch lever is pressed inwardly through the opening 35 and the staff section 6 is forced longitudinally into the section 5. When the end of said section 6 abuts against the inner end of the cap member 33, the opening 26 will be in registration with the opening 21 and the angular or inclined lug 30 of the latch lever will be opposed to the conical end 3| of the pin 32, thus limiting the outward projection of lug 25 by the spring 28 through the registering openings, so that there will be very little projection of the end of this latch lever beyond the outer surface of the staff section 5 to thereby obviate the possibility of the accidental movement of the latch lever to its release position.

Therefore, in this form of the invention, unlike that first described, the latch lever operates to also hold the two staff sections against relative rotation when in their telescoped positions.

In order to move the lever 23 to its release position, pressure is applied to the end of pin 32 with the finger, thereby compressing spring 34 and causing the conical end 35 of said pin to coact with the inclined lug 30 thereby rocking the latch lever and moving its angular end 25 inwardly through the opening 21 of the staff section 5 against the resistance of the spring 28. Staff section 6 may then be moved outwardly to its extended position from section 5, as seen in Fig. 4 of the drawings.

From the foregoing description in connection with the accompanying drawings, the construction, manner of operation and several advantages of the described embodiments of my invention will be clearly and fully understood. It will be seen that either alternative provides a latch means for the telescoping staff sections, which is simple, reliable and efficient in its functional operation, as well as durable and inexpensive in its construction. The described constructions, as to the form and relative arrangement of the several elements, are more or less suggestive, though in actual use, I have found the same to be preferable. However, it is to be understood that in the practical application and development of my present invention, I reserve the privilege of resorting to all such legitimate variations in the details of my present disclosure as may be fairly comprehended within the scope of the appended claims.
