2 Claims. (Cl. 135-40) This invention relates to a telescopic umbrella comprising stick and cover rib parts having a telescopic relation.

An object of the present invention is to provide only two telescopic tube or stick members, the inner stick member being secured to the bottom of a cup-shaped handle.

In the accompanying drawings in which is disclosed an embodiment according to the invention:

Fig. l is a view of the telescopic umbrella in accordanee with the present invention in extended, but not put-up condition;

Fig. 2 is a view of an intermediate position; and

Fig. 3 is a view of the umbrella when fully telescoped.

The umbrella includes a stem 1 and the toe piece 2, the upper rib parts 3 being pivotally connected thereto in a known manner. With the stem 1 is assembled the inner telescoping shaft 4, at the lower end of which is mounted a cup-shaped handle 5. The main runner 6 of tubular form is somewhat elongated and has pivoted thereto intermediate its ends the main stretchers 8, and to the other ends of which stretchers are pivoted the lower cover ribs 9, the rib parts 3 and 9 being telescoped together. With the stretchers 8 are assembled auxiliary stretchers 10, the ends of which are pivoted to an auxiliary runner 11 that is slidably mounted on the stem 1. A lower clamping spring 12 is provided for looking the main runner 6 in known manner.

The main runner 6 has a lower slot 13 at its inner end inwardly of the pivotal connections 7 between the runner 6 and the main stretchers 3 for engaging with the runner clamping spring 12 carried by the inner shaft. A second slot 15 in the main runner 6 is aligned with the aforesaid slot 13 and is positioned outwardly of the pivots 7 for the main stretchers and is also associated with the elamping spring 12. Moreover, the stem has a longitudinal slot 16 arranged in the plane of the runner clamping spring 12,

"ice

by which means the runner clamping spring 12 is forced through the slot 16 when telescoping the shaft 4 and the stem 1. With this, the slot 16 has such a length that not only the clamping spring 12 may pass through it, but also the stem 1 may slidably be moved upon the shaft to an extent that the stem fully coincides with the shaft, without the elamping spring 12 being forced out of the second slot 15 into the shaft.

The mode of handling the telescopic umbrella according to the invention is as follows: From the position of Fig. 1 showing the shaft and the stem in extended condition, the shaft 4 with the handle 5 is first telescoped, and that to such an extent that the runner clamping spring 12 may engage with the upper slot 15 of the rnain runner (Fig. 2). Thereafter, the stem 1 and the shaft 4 are further telescoped. When doing so, the runner clamping spring 15 is first forced back by the lower end of the stem 1, but after that it may engage with the slot 16, the position of the main runner thus being secured by the runner clamping spring 12. At last, the stem 1 is telescoped until the lower end of the stem is stopped by the bottom of the handle, the lower end of the stem 1 coinciding with the main runner 6. In this way, the umbrella is telescoped to the shortest possible length.

I claim:

1. ln a telescopie umbrella, an inner shaft and an outer stem telescoping over the inner shaft, an elongated main runner on the inner shaft, a cup-shaped handle at the inner end of said inner shaft of a diameter greater than the diameters of the main runner and the outer stem, a clamping spring carried by the inner shaft adjacent the handle, said main runner having aligned slots therein aligned With said clamping spring for selective engagement with the spring for mantaining the runner in the cup-shaped handle in the telescoped condition of the umbrella.

2. A telescopic umbrella as in claim l, wherein the inner end of the outer stem has an elongated slot therein to receive the clamping spring when the outer stem is telescoped inwardly over the inner shaft and received in said handle.
