4 Claims.

My invention relates to a new and improved umbrella.

One of the objects of my invention is to provide an umbrella which has certain improvements in construction, over the umbrella shown in U. S. Patent No. 1,911,784 issued on May 30, 1933.

Another object of my invention is to provide an improved construction at the inner or handle part of the umbrella.

Another object of my invention is to provide an improved construction for the sectional ribs of the umbrella.

Another object of my invention is to provide a new and improved means for connecting the runners, to the sectional ribs of the umbrella.

Another object of my invention is to provide a new and improved device for connecting the portions of the sectional ribs of the umbrella to each other.

Other and additional objects of my invention will be set forth in the following description and drawings, which illustrate a preferred embodiment of the invention.

Fig. 8 is an elevation which corresponds generally to Fig. 7, said Fig. 8 showing the respective upper and lower rib sections.

Fig. 9 is an elevation, showing the umbrella in the partially extended position.

Fig. 10 is a sectional View on the line lili9 of Fig. 9.

Fig. 11 is a detail elevation of an upper or inner rib section.

The improved umbrella comprises a pair of telescopic stick sections la. and lb. The upper or outer stick section la. is tubular, and the inner stick section ib is also tubular, and it is slidably mounted Within the outer stick section la..

As shown in Fig. 1, the inner stick section lb is provided with a slot, in which a detent or catch 2 is located. Asshown in Fig. 1, this detent 2 is provided with a metal shank 2a, which is resili- 1935, Serial No. 26,942

ent, and which ts and is held frictionally within the adjacent part of said inner stick section lb.

When the umbrella stick is extended, as shown in Fig. 9, the detent or catch 2 is moved laterally by the resilient shank 2a so that detent 2 engages the lower end of the outer stick section la.. The detent or catch 2 can be forced inwardly, in the usual manner, in order to collapse the stick of the umbrella.

The improved construction of the detent or catch 2 makes it unnecessary to fasten the same to the inner stick section ib, and the frictional grip of the shank 2a., keeps said member 2 reliably in the position which is illustrated in Fig. 1, as well as in the position which is shown in Fig. 9.

A tubular runner 3 is slidably mounted upon the outer stick section la., and the upper or outer stick member la is provided with the usual spring detent or catch 23, in order to hold the runner 3 in its upper position, which is illustrated in dotted lines in Fig. 9. If desired, the runner 3 could have a vertical slot, closed at both ends, above the bottom of the runner, and catch 23 could project through said slot, when the runner 3 is in its upper position.

As shown in Fig. 1, the spring detent 23 is connected to a ring 24. For this purpose, the spring detent 23 is provided with a head H, which is partially located in an opening 29, which is provided in the upper stick member la. An opening 25 is also provided in the upper stick member ia, so that the detent 23 can be moved inwardly, in order to release the runner 3, if it is desired to collapse the umbrella.

The collar 24 is suitably connected to the upper stick section la.

The runner 3 is provided with spreaders il, which are pivotally connected thereto, and said spreaders i are also pivotally connected to the upper rib sections 5a.. The spreaders d are preferably made of tempered and springy metal of solid cross section, like the rib sections.

The spreaders i are pivotally mounted in recesses of the runner 3, by means of a wire ring 5, which passes through suitable openings in the lower ends of said spreaders. The general details of construction which are not specically mentioned herein, are shown in said U. S. Patent No. 1,911,784.

As shown in Fig. 1, the upper end oi the upper stick member la is provided with a collar 3, which is suitably connected to said stick member ia. This connection can be by means of a drive iit, or by any other suitable means.l Said collar 8 has an upper flange, which is externally threaded. A stop-head 5l) is located at the upper end of the stick member Ib, and this member 5i! is provided with an enlarged head, as shown in Fig. 1. A head It has an internal thread, by

means of which it can be screwed into the position shown in Fig. l.

When the stick is extended by moving the inner stick-member ib downwardly, the head 50 enters the outer stick memberla, since head 50 moves in unison with inner stick member Ib. In the extended position of the stick, head 50 is below catch 23. The head 56 makes it impossible to push the inner stick member upwardly, while the spring catch 23 is held inwardly. If theoperator attempts to do this, the head 56 strikes against spring 23. If the top of the tubular inner stick member is open, it is possible to have the rim of the inner stick member engage the catch 23, and either break or bend the catch.

This head Il! serves to clamp the upper end of the fabric covering C` of the umbrella.

In this improved construction, each of the upper rib sections 5a, is provided with a twisted head part 53. This twisted head part 53, is generally perpendicular to the body of said ribsection 5a. The twisted head part is made by twisting the upper end of the upper rib section, through an angle of 90. Said upper rib section has a solid rectangular cross-section. Each twisted part 53 of the rib section 5a is provided with a bore or opening, and a wire ring 9, which is located in a suitable groove of the collar 8, serves to connect the rib sections 5a. in a turnable manner, to said collar S. By making the rib sections 5a. of integral construction, and by twisting their upper ends in the manner indicated, a very sturdy and reliable and cheap construction is provided.

As shown in Fig. 7, the lower end of each rib section 5a, is provided with a channel member 55, which is connected to said rib section 5a by means ci a fastening member 55. As shown in Fig. 7 and Fig. 8, the channel member 55 is provided with perforated ears 51. As shown in Fig. 8, each lower rib section 5b is connected to said ears 57, by means of a pivot pin 58. This channel member 55 limits the turning of the rib section 5b, relative to the rib section 5a, and when the ribs are in the extended position shown in Fig. 9, each channel member 55 provides a strong backing for its associated pair of rib sections.

As shown in Fig. 11, each upper rib section 5d is provided with a portion of reduced thickness, thus providing shoulders 54.

Each spreader 4 is provided with a one-piece member 60, which partially embraces the adjacent rib section 5a. The shoulders 54 provide abutments, thus preventing any relative longitudinal shift between said members and the rib sections 5a. Said members 6l! are turnably connected to the spreaders 4 by means of pins 1. As shown in Fig. 8, the ears 5l are provided with inwardly projecting flanges. The upper ends of the rib sections 5b are twisted, like the twisted ends 53 which have previously been described. Said upper twisted ends of the rib sections 5b fit between the inwardly directed anges of the ears 51.

Referring to Fig. 1, the lower end of the inner stick member Ib is externally threaded, and a head 52 is provided with a recess whose wall is internally threaded. The head 52 can therefore be secured to the lower end of the stick member Ib.

'Ihe head 52 is provided with a cup-shaped flange 52a.. A detent 5I is connected to the inner surface of the head 52. rIhe detent 5! is provided with separated arms Sla, which are of resilient construction, so that the inwardly directed ends of said resilient arms Sla can detachably engage the corresponding flange of the runner 3, when the umbrella is in the collapsed condition.

When the runner is in its bottom position, the bottom of the runner extends over the top end of catch 2, so that said catch 2 is moved inwardly, either wholly or partially. Hence the inner stick member can be pushed into the outer stick member, without further manipulation of catch 2. That is, the bottom of the runner projects below the top edge of the vertical recess which is provided at the bottom edge of the outer stick member, and which catch 2 enters when the stick is extended. The engagement of catch 2 in said slot prevents any relative turning movement between the stick members, when they are in the extended position.

The bottom end of the outer stick-member (which may be made of aluminum) may be reinforced by a ring of hard metal, such as steel or brass, which has a press t on the lower end of the outer stick member. In its lower position, the runner passes over said ring reinforcement.

I have shown a preferred embodiment of my invention but it is clear that numerous changes and omissions can' be made Without departing from its spirit.

I claim:

, 1. An umbrella having a rib section of solid rectangular cross section, one end of said rib section being twisted substantially around the longitudinal axis of said ribsection, relative to the body of said rib section.

2. A rib construction for an umbrella comprising an upper rib section and a lower rib section, said rib sections having bodies of solid and rectangular cross section, the upper end oi the upper rib section being twisted relative to the body thereof and around the longitudinal axis of said upper rib section, a connecting member rigidly connected to the lower end of the upper rib section, said connecting member being provided with lateral flanges having ears which are provided with inwardly directed flanges, the width of the upper rib section being substantially equal to the distance between the adjacent walls of said lateral flanges, the lower rib section having a solid and rectangular cross section, the width of the lower rib section being substantially equal to the width of the upper rib section, the upper end of the lower rib section being twisted relative to the body thereof and being located between the flanges of said ears, and a pin pivotally connecting said ears to the upper end of the lower rib section.

3. In an umbrella, a runner slidably mounted on a telescoping stick, a head having a cup-shaped flange mounted on the handle end of said stick in which the lower end of the runner is located when the umbrella is collapsed, and spring detent means located within said cup-shaped flange and connected to said head, said spring detent means being adapted to engage said runner releaseably.

4. In an umbrella, a runner, a spreader pivotally connected to said runner, a pivotally mounted rib having shoulders intermediate the ends thereof, and a connecting member for pivotally connecting said rib to the spreader, said connecting member passing at least partially around the rib and having its edges substantially abutting said shoulders.
