13 c aims. (61.135 36) This invention .relates to blunt tips; for the ribs 'ofumbrellas the term umbrella being taken to include parasols'. i i

I At present many tips are differing prin- "5 cipally in the methods by which the fabric is attached to the tip; and the tip to the rib.. All of these present tips; however, are pointed at the ends and so-present a ,hazard to persons walking or standing. close to the openumbrella or parasol. It is the principal "object of my invention to remove this hazard by providing a blunt tip, while at the same time performing all the functions which the present day tips perform.

It is another objectv to prolongthelife of the fabric by reducing fabric stresses at the rib p H It isanother object ofzthisinvention to provide a tip which will beso'decorative as'to enhance theappearance of theentire umbrella.

It is another" object to effect economies by re-. ducing the number' of ribs'i'equire'd'.

According to my invention,'I provlde a rib end member widened alongthe periphery of the umbrella but flattened and disposed below the fabric, and a shallow decorative protrusion Onthe outside of the fabric.

Various methods of. constructing said rib end.

member and said-decorative member, separately or in one piece, are shown in the accompany ing drawing, in which I e Fig. 1 is a plan viewof a rib'and tip assembly wherein the tip isformed of a plastic member arranged to receive the rib and retain the fabric.

-Asingle molded or cast member 1 designed to perform the functions of the elongated support and of the decorative member is shown in Figs. 1, 2 and 3. The member l has ahole View of a of w I retaining the fabric on an elongatedjribtip by therein into which is inserted the rib R, which is affixed therein by means of the pins 8 closely fitting beside the corrugations 9 in the ribR.

The fabric Fis placed in the slot. it] andis held 1 by the seam oi the fabric and .by pins in the enlarged end portions H of the slot Ill. I

A simplified form of mounting the strip l6 of decorative material is shown in the exploded view of Fig. 5, in which the shell I-i shown in Figs. 7

and dis used as a frame forretaining the strip i5,..whil e the tongues l8 and]? are bentover inside the holes !9 to simultaneously. affix the shell H to the supporting member l5 and to anchor the'iabric F. Anotheramethod of deccrating the rib tip is to mount jewels in-the shell indicated in Fig.- 4;,

The supporting member pressed fromsheet metal, as indicatedvin the plan view of Fig. 6, or, cast or molded in a may, be. spot 'Wldfid, soldered or brazed to the rib R. If cast or molded, it may either be cast-or molded integrally with the rib R or afiixed in the manner shown in Fig.1;

One method of attaching a molded or'f'cast l5 may be I either I If constructed from sheet metal it decorative pieceis shown in Fig. 9, in which the 1 elongated metallic member 24 is molded or cast into the decorative, piece 23, or affixed to the under surface thereof by means suchas'solder ing' erbrazing. Thismember 24 is inserted inholes 25 during assembly and used to; anchor thev fabric and affix the member 23 in place on the Alternatively, the member 24' may be a screw. i V H Another method of jattaching the. fabric' is to use buttons 28. as shown ,in Fig. 10;. .Recesses 29 are provided in the rib tip;j3fi for the buttons whichshould preferably be of the form having no holes on the outside but an eye 32 on the inside. The buttons 28 may alternatively be sewn in place or attached by staples to theholes and 3!. sewed in place without the use of buttons;

No restriction is placed on the position, of

Inall of these'designs, the life of the fabric I is considerably increased over standarddesigns,

because the large area over which the fabric is attached at each rib .tip results in lowered fabric stresses. 7

In the design of rib tips according to my invention, no restrictions are placed uponthe relative thickness and width of each tip, or upon the angles at which said tips may be set, in order to allow the widest latitude for decorative design. Neither is any restriction placed upon the thickness of the member which is retained afiixed over the fabric, as 'l' in Fig. .3 and i"! in Fig. 6. I

It may be seen that an umbrella maybe con structed with a reduced number of ribs when each rib is equipped with a broadened tip, which will effect a considerable economy .in manufaca ture.

'Other methods of constructing a widenedtip and decorating it may be used, but the -combi -na tion of safety and decorative features is claimed as follows: I
