6 Claims.

My invention relates to improvements in folding umbrellas, and more particularly in umbrellas of the type in which the ribs comprise three -telescoping sections, the median sections being freely movable on the inner rib sections and having the braces attached to their inner ends, and the outer and median rib sections being provided with locking means for holding the outer stick sections in extended positions, and in which the inner rib sections are adapted to disengage said locking means when the ribs are being collapsed. One of the objects of the improvements is to provide an umbrella of this type in which the median and outer rib sections are uniformly moved inwardly and with their locking means into engagement with the inner rib sections, so that said locking means are simultaneously disengaged. This is important for the reason that the ribs might be injured if only one or a few of the outer '20 sections remain in locked position so that it must take up the whole pressure of the hand when the ribs aretelescoped inwardly. In the preferred construction subsidiary braces and a subsidiary runner are provided which insure such uniform movement of the median and outer rib sections.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawing:

Figs. 1 to 4 are elevations showing the frame of the umbrella respectively collapsed, extended and in two intermediate positions, Fig. 1 showing the umbrella collapsed, Fig. 2 showing the same with the outer rib sections extended and the other parts collapsed, Fig. 3 showing the same in the position in which the handle and the outer stick member is further telescoped outwardly, and Fig. 4 showing the same in completely extended position, the dotted lines in Fig. 4 showing the frame in open position,

Fig. 5 is a detail sectional view on an enlarged scale showing the joint and the locking means of the outer and'median rib sections and the outer end of an inner rib section which is about to disengage the said locking means,

Fig. 6 is an elevation viewed from the left in Fig. 5, and

Fig. '7 is a sectional elevation showing a detail.

In the construction shown in the figures the frame of the umbrella comprises a stick composed of telescopic members i, 2 and 3, the stick member 3 being telescopingly located within the stick member 2, and the stick member 2 being located Germany August 3, 1938 within the stick member i.

To the upper or inner stick member I a crown 4 is fixed which has the ribs jointed thereto.

The said ribs comprise inner sections 5 and median outer sections 6 and i, which are in telescopic engagement with one another. The upper or inner rib section 5 may consist of a solid rod and the median and outer rib sections 5 and consist of rods which are U-shaped in cross section. The rib section 5 engages in the channel of rib section 6 engages in rib section i.

the rib section 6, and the the channel of the outer The cover 8 of the umbrella is ati1 engaging in a slot 25 of the runner, and in the expanded position of the umbrella the runner I5 is supported on a spring latch I6.

To the lower stick member 3 a handle 24 is secured.

To the inner or upper ends of the outer rib sections 1 sleeves iii are fixed which are slitted at their opposite ends to provide spring. latches l9 and 20, the said spring latches being bent inwardly and into positions for engaging in notches 2| and 22 made in the webs of the rib member 6, the said notches providing shoulders locking the sleeves i8 and the outer rib sections 1 in position on the median rib sections 6.

The spring latches i9 prevent inward movement of the rib sections I, and the spring latch 20 prevents the said rib sections 1 from being pulled outwardly and out of engagement tions 6.

with the median rib sec- Similar latches 26 are provided at the inner ends of the median rib sections 6 for preventing outward movement of the said rib sections out of engagement with the rib sections 5. These spring latches have been shown in Fig. 7.

When the umbrella is collapsed from the position shown in Fig. 4 and into the position shown in Fig. 3 the median rib sections 6 are telescoped inwardly on the rib sections 5, and there is practically no resistance to such inward movement,

because there are not looking members preventing such inward movement of the rib sections, and the auxiliary braces ll do not exert pressure on the main braces 9, the said auxiliary braces H acting on the main braces 9 only when the umbrella is in the expanded position shown in Fig. 4 in dotted lines.

Near the end of the inwa'rdmovement of the rib sections 8 the outer ends 230i the rib sections get-into positions for engaging the spring latches i9, which thereby are "pressed outwardly and out of engagement withthe notches 2|, the rib members 5 being prefer ably tapered at their outer ends. Thus the looking members l8 connecting the rib sections 6 and I are disengaged-so that also the outer rib sections 'imay be telescoped inwardly and into the umbrella the auxiliary braces ll insure simultaneous and uniform inward movement of the rib sections 6 and therefore simultaneous disengagement of the spring latches l9, the said auxiliary braces being all jointed to the same runner i6 and always holding all the ribs in equal angular positions relatively to the stick.

Further when the outer rib sections l are telescoped outwardly from collapsed position into extended position the resistance to be overcome is but small, because at this time the cover is loose, the said cover being expanded only afterwards by the auxiliary braces II when the umbrella is opened.

When the closed umbrella is collapsed at first the inner rib sections andthereafter the outer rib sections are telescoped inwardly. When the umbrella is extended from the collapsed position shown in Fig. l the rib sections are telescoped outwardly in the reverse order, the outer ends of the outer rib sections 1 are pressed by the hand on the handle 24, and they are telescoped outwardly together with the outer stick member 3, until the locking members l8, l9, 2| are engaged, the rib sections 1 being prevented from being pulled out of engagement with the rib sections 6 by the spring pawls 20 engaging in the notches 22. This operation does not require much force because the cover of the umbrella is not stretched, and the rib sections 5, 6 and the stick members I and 2 do not take part in this operation, because the spring I! is held by the stick member 2 in retracted position and out of engagement with the slot 25 of the runner l5. When the umbrella is further extended the spring I! engages in the said notch 25, and thereafter the runner I5, the main braces 9, the auxiliary braces II, the auxiliary runner i4 and the rib sections 6 are pulled outwardly.

I claim:

1. In a folding umbrella, a frame comprising a stick, ribs each comprising three telescoping sections, the inner and median rib sections being freely movable relatively to each other, a runner,

bragesjointed to said runner and to the inner 'ends'o'f" the median rib sections and adapted to hold the said median rib sections extended, means engaging said stick and braces adapted when the umbrella is open to hold said braces in positions for holding said median rib sections extended, and locking members adapted 'to hold the outer rib sections relatively to said median rib sections in extended positions, said locking members being in position for being disengaged by 5 sections, the inner and median rib sections being 10 freely movable relatively to each other, a main runner, main braces jointed to said main runner and to the inner ends of the median rib sections and adapted to hold the said median rib sections extended, a subsidiary runner, subsidiary braces jointed to said subsidiary runner and to said main braces and adapted when the umbrella is open to hold said main braces in positions for holding said median rib sections extended, and

locking members adapted to hold the outer rib sections relatively to said median rib sections in extended positions, said locking members being in positions for being disengaged by said inner rib sections when the umbrella is being collapsed-.

3. A folding umbrella as claimed" in claim 1,

v in which the said inner rib sections are telescopingly mounted within said median rib sections, and in which said locking members project into the paths of said inner rib sections and into positions for being thrown thereby into nonlooking positions. I

4. In a folding umbrella, a rib comprising three telescoping sections, one formed near its end adjacent to another section with a shoulder, and

a locking member in the form of a sleeve fixed to the end of said other section and carrying a spring in position for locking engagement with said shoulder, said spring being in position for being disengaged from said shoulder by the rib section remote from said locking member and shoulders.

5. In a folding umbrella, a stick, a rib comprising three telescoping sections, a locking device between the outer and median sections consisting of a sleeve carrying a spring nose and a notch,

said sleeve and notch being provided respectively on said outer and median sections, said spring nose being in position for being disengaged from said shoulder by the inner rib section.

6. A folding umbrella as claimed in claim 1,

comprising a stick made in telescoping sections, a handle on the outer stick section in position for having the outer ends of said outer rib sections assembled thereon, and a spring latch on the outer stick section for holding said runner when the umbrella isclosed with the stick in extended position, said spring latch being on its stick section in such position that when the collapsed umbrella is being extended with the said outer rib sections assembled on said handle it is held by the median stick section in retracted position and released therefrom only when the said outer rib sections are substantially in the positions in which the said locking members are in positions for getting into locking engagement.
