COLLAPSIBLE UMBRELLA Application filed November 27, 1929. Serial No. 410,188.

This invention relates to new and useful improvements in umbrellas and has more particular reference to a novel collapsible umbrella.

The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, dependable in use and efficient in action, and which can be manufactured and sold at a reasonable The invention proposes a collapsible handle, collapsible ribs mounted on the top 7 thereof and consisting of inner and outer rib sections, covering material attached onsaid ribs, means for holding the handle collapsed, means for holding. the handle extended,- means for holding the inner rib sections collapsed or extended, and means for holding the outer rib sections collapsed or extended.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the 1 v various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure I-- Fig. 1 is a side elevational view. of the unibrella in fully collapsed condition.

Fig. 8 is a fragmentary enlarged detailed view of a portion of Fig. 7.

Fig. 9 is an enlarged fragmentary view of the upper portion of my umbrella, as shown in Fig. 2.

The collapsible umbrella cons sts of a collapsible handle 10, collapsible ribs mounted on the top of the handle lOand consisting of each other for limiting the pivoting of the a top plug 14. anda flange .25 on thebottom H dle section 16. Flanges 1'7 are arranged on the intermediate and bottom handle sections 15 and 16 and eoact with each other to limit the eXtended'position of these parts. .Slots 18 are formed in the intermediate handle section 15 and receive pegs 19 projecting from the top handle section 14 for 79 limiting relative movements of these parts. In addition, flanges 20 are arranged upon the top and intermediate handle sections and coactiwith each other for limiting the extended position of these parts. a The inner and outer rib sections 11 and 12 of each of the ribs are pivotally connected together by rivet pintles 21. Lugs 22 project from the rib sections and are engageable with rib sections into aligned position or into a position in which the inner rib section is horizontal and the outer rib section may assume downward vertical positions. Dot and dash lines 23 in Fig. 2 indicate the vertical 35 position of the outer rib section while the full lines indicate the aligned positions. A. coaxial spring 2 1 is aranged upon-the rivet pintlev 21 and acts between the inner and outer rib sections for normally urging the outer rib section into the vertical when the inner rib section is in the horizontal,

The said mounting of the collapsible ribs upon the handle consistsof a vertical 'rod 25 rotatively mounted onthe'top handle section handlesection 14. The handle section 14 has of the rod 25 rotatively engaging in the plug 14 for nonslidably and rotatively connecting these parts. A flange on the rod 25 rotatively engages in the disc 26 for nonslidably and rotatively connecting these parts. A collar 27 projects from the disc 26 and is provided with lugs 28 engaged by pintle pins 29 pivotally supporting the inner rib sections. The pivotal supporting is near the inner end of the inner rib section as may be seen from an inspection of Fig. 2.

The said covering material 13 is of conventional construction, that is, it may be of cloth and is attached upon the ribs. The means for holding the handle in collapsed condition consists of a latch 30 mounted upon the bottom handle section 16 and engageable with a hook 31 on the top handle section 14 so'as to hold the sections of the handle together.

The means for holding the handle is extended condition consists of an expansion spring 32 within the handle and acting be tween the top and bottom handle sections so as to normally urge these sections apart. This spring is so designed that it does not extend the handle into. its fully extended position. Preterably the amount of extension should be about eighty per cent. The means for holding the handle in fully extended position is concluded with spring catches 33 mounted upon the intermediate and top handle sections and engageable against the top edges of the bottom and intermediate handle sections respectively. After the spring 32 has extended the handle approximately eighty per cent,the sections must be manually pulled apart for accomplishing the -lnll extension.

Tl e means for holding the inner rib sections collapsed or extended consists ot-a member 34 slidably connected with the. disc 26, as for example by pegs 35 projecting from the disc 26 and engaging thru apertures formedin the member 34. This member 34 is threadedly engaged upon the vertical rod 25. A tree collar 36 slidably mounted upon the rod 25 and is provided with lugs 37 formed with elongated slots 33 accommodating pintle pins 39 engaging thru the inner ends of the inner rib sections 11.

A spring 40 is connected between the meniber 34 and the collar 36. In the lowered position of the collar as illustrated in Fig. 1, the spring 40 acts as an expansion spring so as to normally urge the collar downwards and thus pivot the inner rib sections into extended positions. The vertical rod 25 is'formed with a head portion 41 which may be manually rotated so that the member 34 is raised. In the raised position, the spring 40 acts as a tension spring and draws the collar 3.6 upwards so as to correspondingly pivot the inner rib sections into the collapsed condition.

The means for holding the outer rib sections in collapsed or extended-positions consists of a drum 42 attached upon each of the I outer rib sections and coaxially on the rivet pintle 21. Cords 43 are Wound upon these drums and connect with main cords 44 extended thru the hollow collapsible handle 10 and attached on their inner ends upon the bottom handle section 16. A spring 45 is interposed between the ends of the cords 44.

The operation of the umbrella may be easily traced by first assuming the collapsed position shown in Fig. 1. For extending the umbrella, it is merely necessary to manually disengage the latch 30 so as torelease the hook 31. Thereupon spring 32 urges the handle 10 into eighty per cent of its extended position. In this condition the outer-rib sections 12 may assume the vertical position indicatedby the dot and dash lines 23. This is accomplished by proper rotation of the rod 25 for lowering the member 34 so that the spring 40 urges the collar 36. downwards.

Next the handle may be fully extended manually and the position is maintained by the catches 33 assuming their operative positions. Upon complete extension ofthe handle 10, the cords 43 and 44 are drawn upon under the resilient action of the spring 45 so as to move the outer rib sections into their extended positions.

lVhile I have shown and described the preferred'embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the inven? tion as defined. in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. In a collapsible umbrella, a handle, a top disc above the top of said handle, a rod rotatively and nonslidably mounted on said handle and rotatively and nonslidably mounted through said disc, :1- head formed on the extended end of said rod, a collar fixed on said disc, rib sections pivotally mounted on the collar and having their inner ends extended towardssaid rod, a free collar on the rod and pivotally connected with the inner ends of said ribs, a member threadedly engaged on said rod, means for slidably supporting said member and restraining rotations, and. a spring acting between said member and said free collar so that in one position of the memher the spring is under compression to extend the rib sections and in anoth'erposition ofsaid member obtained by rotation of said rod said spring is under tension to fold said rib sections. 1
