' v 8 Claims. (Cl. 135-20) This invention relates to umbrellas and particularly to an improved inflatable umbrella, an object being to provide a construction which is simple and which may be readily nested in a 5' small closed receptacle when not in use.

Another object of the invention is to provide a collapsible umbrella with the canopy portion made of rubber and the other parts of various materials and arranged to act both as a pump 10 for inflating the canopy and as a handle.

A further object, more specifically, is to provide in a collapsible umbrella acanopy portion made of inflatable rubber and associated with a tubular container and a piston which uses the container as a cylinder for compressing and directing the air into the canopy to inflate the same. L

In the accompanying drawings- Fig. 1 is a longitudinal vertical sectional view 20 of an umbrella disclosing an embodiment of the invention, with the parts shown in nested position;

Fig, 2 is an enlarged fragmentary sectional view showing the deflating valve illustrated in 25 Fig. 1;

Fig. 3 is a sectional view through Fig.- 2 ap-v proximately on the line 3-3;

Fig. 4 is an enlarged fragmentary sectional view through Fig. 1 approximately on the line so I Fig. 5 is a vertical sectional view through the umbrella when in use;

Fig. 6 is a top plan view of the umbrella when in use, the same being on a reduced scale;

Fig. 7 is an enlarged fragmentary sectional view through Fig.6 approximately on the line Fig. 8 is an enlarged fragmentary sectional view through Fig. 6 approximately on the line so Referring to the accompanying drawings by numerals, I indicates a casing which forms-part of the handle when the umbrella is in use. In this casing, when the parts are nested, is a can- 15 opy2 which is adapted to be inflated to appear as shown in Figs, 5 and 6. The canopy 2 is made from an upper and a lower sheet of thin rubber 3 and 4 cemented or vulcanized together at 5, and carrying at their inner ends thickened zones 6 and 1 for reinforcing purposes. In connecting the top and bottom members 3 and 4 of the canopy 2, the parts are preferably vulcanized together when the portion is exterior and then the entire device is turned inside out so that th 5 parts will appear as shown in Fig. 5.

bers l9 and 20 to act on g I, which casing may be metal.

inga washer 31 preferably of to by cement or in any other desired manner. ,A 10

valve seat It is arranged at I2, said valve seat having the end of the rod an opening l5, as

- shown in Fig. 2, which is adapted to be closed by a soft rubber valve member [6 connected to the lower end I! of a ring l8. s ring isprovided with V-shaped members I 9 and which coact with a pin 2i. The ring I8 is of spring metal and normally is in the position shown in Fig, 1. The fact that the portions 2i and 22 tend to move together, as shown in Fig. -1, causes the mem- 20 the pin 2i to pull the valve member l6 against its seat. When it is desired to deflate the canopy 2, ring it is pushed downwardly to the position shown in Fig. 2, whereupon the'same action of the'portions 2i and 22 will tend to hold the valve open.

From Fig. 1 it will be seen that the rod I2 is provided with a longitudinal passageway 23 into which the valve l6 extends and which merges into sight apertures 24 and 25, whereby air interior of the canopy 2 may readily escape when the valve i6 is open. It will be noted that a cord or other element 26 binds the canopy to the rod i2 around the bore l3 and a similar cord or ligament 2! binds the lower part to the rod l2 immediately below the inlet valve 28. This valve is provided with rubber valve members 29 and 30. The valve members 29 and 30 are connected by a resilient piece of rubber 3|, or if desired a coil spring could be used whereby the valves normally rest against their seats 32 and 33 screwed into suitable apertures in the rodl2. It will be observed that there is provided a longitudinally extending inlet bore or air passageway 34' which extends from the valve seats 32 and 33 downwardly, as shown in Fig. 1, and through a bottomwasher 34 and associated parts. A cap 35 of any. desired material is screwed into the casing The cap 35 may also bemetal, rubber, wood, or material. The washer 34- with its associated parts, including the rod l2, forms a pump piston and includes an externally threaded knob 36 havmetal. A second metal washer 38 is held in place bya nut 39 55 other suitable screwed on to the lower end of the rod ii. In this way all the parts are rigidly secured together.

Whenit is desired to use the umbrella, the cap 8 at the top, as shown in Fig. 1, is unscrewed and the parts are pulled out until the entire canopy is exterior of the casing l. The rod I! may be grasped, or cap 8 maybe grasped, and the piston including the washer 34 'reciprocated, whereupon it will act as a pump piston and force air from casing I upwardly through the passageway 34 and out through the inlet valves 29 and 30 into the interior of the canopy 2. This action continues for a short time or until theicanopy is fully inflated as shown in Fig. 5. After the canopy has been fully inflated, the knob 36 is moved upwardly and screwed into the sleeve III, as shown in Fig. 5, whereupon the umbrella is ready for use.

When it is desired to nest the umbrella, as shown in Fig. 1, the wire handle i8 is depressed to the position shown in Fig. 2 and the air will immediately begin to escape. If desired, the canopy may be squeezed between the ends to force the air out quickly and then the knob 36 is unscrewed and the parts forced into the casing l,

as shown in Fig. 1. After this has been done the cap 8 is screwed into place and the handle 18 pulled upwardly.

In making the canopy, upper and lower sheets of elastic rubber are used-and in order to give the desired appearance and stifi-ness to the rubber sheets they are vulcanized along certain lines, for instance, a number of lines 40 are vulcanized. from the periphery to the thickened portion 6. In Fig. 6 eight of these lines have been provided. As shown in Fig. 8, these lines connect the top and bottom sheets of rubber for the full distance between the thickened parts 6 and 1 and the periphery. Auxiliary lines ll and are provided between the principal lines of vulcanization, said auxiliary lines being vulcanized particularly as indicated in Fig. '7. These auxllairy lines connect the top and bottom sheets of rubber together in the same way as the principal lines 40 but extend for a less distance inwardly from the periphery. In this way the periphery is stifiened by the vulcanized edges 5 and the various radial lines of vulcanization just described, while the center. is stiffened by the thickened or reinforced portions 6 and 1, whereby when the canopy is inflated it will appear substantially as shown in Figs. 5 and 6.

When the parts are nested, as showninFig. 1,

the umbrella is so small that it may readily be carried in the hand bag or possibly in the pocket of the wearing apparel'of the person using the umbrella.
