PARASOL AND UMBRELLA.

Application filed March 15, 1927. Serial No. 175,495.

This invention relates generally to improvements in parasols and umbrellas, or similar articles, but specifically has to do with certain novel and unique means for re movably securing the usual tops of said parasols or umbrellas on their supporting frames.

Another object of the invention is to provide means for releasably securing the top to said ribs at a plurality of points inter 3? mediate the tips of said ribs and the central parts, all as will be described more fully 7 figure the cover or top of the parasol is portion of said top and wherein said top is assembled in such a manner as to present a foundation for attaching said above means to the top.

5 Another object is to provide a parasol or umbrella composed of light and durable parts and simplified means in relation there to for securely retaining the covers thereof in their proper position, until changed or re- 3 newed.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of shown connected thereto.

Fig. 4 is an elevation of certain clips.

Fig. 5 is another elevation thereof taken at right angles to Fig. 4.

Fig. 6 is a sectional view, slightly enlarged, on the line 66 of Fig. 1, to illustrate the folding of the meeting ends of the several segments composing the top and the method of attaching the clips thereto.

Fig. 7 is an enlarged elevation of one of the outer corners of the parasol to show the connection between said top and the knob; and

Fig. 8 is an elevation of one of the knobs.

Referring now in detail to the accompany ing drawings, numeral 10 denotes generally my improved parasol or umbrella, the same being provided With a. cover or top 11, composed of a plurality of segments, having a central opening at the top thereof for securing toa tip 12, (see Fig. 3), carried by the usual stem 13. This stem will be provided, of course, with the well-known handle of any wanted design, but since it forms no part of the instant application an illustration thereof is deemed unnecessary.

Referring to Figs. 2 and 3 of the drawings it is noted that said tip 12 is provided with a central bore 14, extending part-way therein for the reception of the upper portion or extremity of said stem 13, that portion of said tip 12, adjacent the base thereof, being cored out to define a concavity 15 into which may be seated the usual upwardly directed projection of the annulus 16, (see Fig. 1) to which latter is pivotally secured the several ribs 17 of the parasol. Referring again to said tip 12, and especially Fig. 2, an annular groove 18 is observed as positioned intermediate the-base and top portions of the tip, while the extreme basal portion is beveled outwardly to define a flared portion 19, and, further, apertures 20 encircle the groove 18 and extend through said tip and into the concavity 15.

Continuing now with the general description of the complete structure, let 21 denote the clips adapted to releasably secure each, of the ribs 17 to the top, said clips comprising spring lateral arms 22 and 23 and prongs 24 for affecting connection between said clip and its individual'fold or crease of the top.

The means for securing the outer corners of the top 11 comprises a knob 25, (see Fig. 8) having a central bore 26 extending partway into the shank portion 27 of said knob and a transverse opening 26 extending there- 'through and at right angles preferably to said bore 26. Attention is now directed to the particular form of said knob and itwill be observed that said shank portion 27 is diminished outwardly to form a graceful reduced portion 28 blending into a neck 29 adjacent an enlargement 30. This enlargement 30 being at the outer portions of the complete parasol ornamentation thereof is expedient and hence it is within the province of my invention to decorate the same with different cuttings in the form of annular projections or flutes to accomplish this purose.

p The foregoing description comprises the main elements of my invention and I will now proceed with the details of construction and ormation to the complete article.

As a first step said tip 12 is inserted within the central opening at the top of the segmental cover 11 until it abuts the annular groove 18. Here it is secured by any suitable means, though I prefer to use stitching, the same being passed through the apertures 20 and thus interlocking the said cover within the groove, as clearly shown in Fig. 3. The tip 12 may now be inserted over the stem 13 and gently tapped to effect a reasonably tight connection, but in all events said tip may be removed in the future by a strong pull outwardly thereof, as will appear hereinafter. The concavity 15 now fits into the projection at the top of the annulus 16 and a neat fit is assured. In securing the outer corners of the cover 11 to the ends of the ribs 17, the material adjacent said knobs 25, (which have been previously affixed to the ends of the ribs), is wrapped partway around the shank portion 27 and including the reduced portion 28, whereupon cord or thread 31 may be stitched through said opening 26 and continuously wrapped around the adjacent portions 32 and 33 of the cover which partly encircle said shank portion 27 of the knobs 25. Figure 7 clearly shows this construction and it should be carefully observed that the reduced portion 28 is also encircled by the cover and the tapered construction of said portion 28 tends to resist the pull exerted thereon when the parasol is in opened position. This is a feature of some importance.

Hereinbefore the cover or top 11 of the parasol has been referred to as segmental. By this is meant that the entire structure of the top is made up of a plurality of sections stitched together to form the whole. The manner of connecting the several segments is clearly shown in the typical section in Fig. 6. Here it is noted that the segment A is folded upon itself, the end thereof being folded laterally as indicated at 34, and that the section B is wrapped thereover, the edge portion thereof terminating over the edge portion of its companion section A. This wrapping 35 is then stitched to the lateral fold 34 of said section A, as indicated at 36. By this construction a well-defined means for securing the clips thereto is afforded, and as shown in Fig. 6, said clips 21 are positioned upon the free edges of the sections A and B and the prongs 24 inserted through the stitched portion and bent to make a tight fastening.

' These clips are positioned intermediate the militia ends of the ribs 17 and directly thereover and thus it is only necessary to spring same into said clips, as shown in Fig. 6, the spring arms 22 and 23 thereof releasably securing same in position.

In the event it is desired to dismantle the construction, it is only necessary to retract the knobs 25 from the ends of the ribs 17, individually release the latter from each of the clips 21 and upon lifting the tip 12 from the stem 13 the entire top of the parasol is freed from the ribs and other structure, and when it is understood that said covers are desired for re-mounting, that same will be obtainable, equipped with the tip 12, and clips 21 and knobs 25 intact, the fact that an instant act will remount a parasol cover and secure same positioned to an old frame, so that a general newness appears, becomes quite apparent.

By my invention the tops or covers of a parasol or umbrella may be removed and replaced with a minimum amount of effort and by an inexperienced person. The various parts may be purchased at a reasonable price and a variety of colors may be had for parasols in accordance with the desires and taste of the individual. The tip and knob may be made of celluloid or similar material and the clips should preferably be brass to render the structure rust-proof.

lVhile the above presents the invention in its preferred form, right is reserved to make such changes and alterations which fall within the scope of the appended claim.

I claim:

In a parasol having a segmental top, the edges of the adjoining segments of said top being folded upon themselves to provide a stitched upstanding portion, a clip adapted 1 to removably secure said top to a rib of the parasol, said clip comprising lateral prongs adapted to pierce and effect engagement with said upstanding portion of said top and presenting substantially parallel resilient arms adapted to releasably engage said rib.

In testimony whereof I aflix my s' nature.

OSCAR I AI-IN.
