Jan. 3, 1956 w. SMYRNOW REVOLVING FAN PARASOL Filed Nov. 2, 1953 IN VEN TOR.

SMYRNOW BY W 8%; Army/m United States Patent REVOLVING FAN PARASOL William Smyrnow, Brooklyn, N. Y. Application November 2, 1953, Serial No. 389,722 9 Claims. (Cl. 135-16) This invention relates to new and useful improvements in parasols.

On many occasions when using a parasol it is necessary, in order to avoid discomfort, to protect oneself against the temperature as well as the sunshine. With this in mind, the primary object of the present invention is to provide a parasol with apparatus for creating a current of air directed over the body of the user of the parasol.

Another object of the invention is to provide a parasol with apparatus for creating a current of air which is readily actuated by the fingers of the hand of the user that holds the parasol.

A further object of the invention is to provide a parasol with apparatus of this kind which is inconspicuous and which is highly efficient in operation.

It is further proposed to produce a parasol with apparatus of this kind which is simple and rugged in construction and which can be manufactured and sold at a reasonable cost.

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 various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a side elevational view of a parasol embodying my invention.

Fig. 2 is a sectional view of the top of the parasol.

Fig. 3 is an enlarged vertical sectional view of the handle portion of the parasol.

Fig. 4 is a fragmentary elevational view of the connection between the stick of the parasol and the driving member for rotating the stick.

Fig. 5 is a side elevational view of an air agitating web or wing member.

.Fig. 6 is an enlarged cross-sectional view taken on the plane of the line 66 of Fig. 3.

Fig. 7 is another enlarged sectional view taken on the line 7-7 of Fig. 3.

The frame of the parasol is of the usual construction comprising ribs 10 pivotally connected to an upper collar 11 fixed near upper end 12 to stem or stick 13. Braces 14 are pivotally connected at one end 15 to the ribs and at the other end 16 to runner 17 encircling the stem or stick 13 and capable of sliding thereover. The cover 18 preferably of flexible fabric material is fixed to ribs 10. Catch 19 pivotally mounted and connected in a slot in the stem or stick 13 has an outward spring movement for securing the lower runner 17, ribs 10, braces 14 and cover 18 in an elevated position, as shown in Fig. 1.

According to the present invention, webs or wing members 20 are secured atone end to the runner 17 by hooks 21 secured to one end of the webs, and at their opposite ends they are stitched to the tips 22 of the ribs. Intermediate their ends, the webs or wing members are connected to the ribs at their juncture with the braces 14 2,729,220 Patented Jan. 3, 1956 i so that the upper end edges of the webs or wing members vstem or stick 13 of the parasol.

the parasol at the top of the stem or stick including the extend along the braces and along the ribs from the ends of the braces outwardly thereof to the tips 22. The webs fold with the cover upon closing the parasol.

The movement of the air is created as by the webs or wing members 20 being transversely vertically inclined and rotated with the top of the parasol including the cover, ribs and braces. Such rotation of the parts is accomplished by rotation of the stem or stick 13 at the handle portion thereof.

For rotating the stem or stick I provide apparatus carried by a tubular handle 23 closed at its outer end by a plastic cap 24 screw threaded onto the handle, and at its inner end by a plastic cap 25 screw threaded onto the inner end of the handle. An elongated plug member 26 is rotatably mounted in the handle and has a squareshaped socket portion 27 opening toward the top of the parasol for receiving the reduced bottom end 28 of the stick or stem 13. The plug member is formed with a flange 29 inwardly of its top end which loosely seats on the top end of the handle and positioned between said top end and the inner cap 25 to hold the plug member in the handle. The bottom face of the plug member is formed with ratchet teeth 30.

A crank device 31 is pivotally supported on the inner face of the outer cap 24 of the handle by a pivot pin 32 formed integrally therewith. The crank device is formed with an upstanding lug 33, and slidably supported on the lug 33 is a cylindrical clutch member 34 having ratchet teeth 35 on its upper face adapted to mesh with the teeth 30 on the plug member 26. A pressure coil spring 36 encircles the lug 33 and has one end seated on the top of the crank device and has its other end impinging against the bottom face of the clutch member 34 for urging the ratchet member with its teeth 35 upwardly so as to force said teeth 35 into mesh with the ratchet teeth 30 of the plug member.

The slidable lug is provided with a key 33 adapted to slidably engage in a keyway 34* formed in the bottom portion of the clutch member 34.

The handle 23 is formed with a cutout portion 37 providing a ledge 38 at the bottom of the handle, at one side thereof. A pivot pin 39 is mounted at the top of the sidewall 40 of said cutout portion and extends radially of the handle. An elongated lever member 41 has one end 42 hooked around the pivot pin for pivotally supporting the lever member. The other end 43 of the lever member is enlarged and is held outwardly of the handle 23 by an elongated spring 44 which is bent upon itself midway its ends and has one leg 45 secured to the inner wall 46 of the cutout portion of the handle, the other leg 47 impinging against the enlarged end 43 and urging it outwardly.

A toggle link member 48 has one end operatively connected to the crank device 31 and has its other end pivotally connected to a bar 49 slidable along the top of the ledge 38 at the bottom of the handle 23 and guided by a loop 50 secured to the ledge. The outer end of the slidable bar 49 is formed with a loop member 51 for connection to a hook member 52 formed on the rear of the enlarged end 43 of the lever member 41.

In operation, inward pressure by the hand of the user on the lever member 41 will force said lever member inwardly which in turn will slide the bar 49 along the ledge 38 of the handle andmove the toggle link member 48 thereby reciprocating the crank device 31. The ratchet teeth 35 on the clutch member 34 and the ratchet teeth 30 on the plug member 26 being in mesh by virtue of the spring 36, the reciprocating movement of the crank device is imparted to the plug member 26 and to the supported This rocks the parts of cooperation of the spring 44 when pressure on the lever member 41-is released;

While I have illustrated and described the preferred embodiment of my invention, it-isto be understood that I do not limit myself to the precise construction herein disclosedand the right is:reserved-to all changes and modifications coming within the scope of the invention as=defined in the appended claims.
