May 28, 1963 R. M. ONEIL UMBRELLA WITH STAND Filed Aug. 17, 1960 IN VEN TOR.

L ,N E M*m T m A 0 N United States Patent 6 3,091,249 UMBRELLA WITH STAND Rose M. ONeil, 292 Butman Road, Lowell, Mass. Filed Aug. 17, 1960, Ser. No. 50,238 10 Claims. (Cl. 13516) This invention relates to a portable, foldable umbrella stand, or support, of light weight and inconspicuous appearance such that it may be continuously carried, ready for use, on the tip of an umbrella.

One object of the invention is to combine a strong, low cost, collapsible support with a conventional umbrella which permits the user to place a wvet, closed umbrella, in vertical position, in a sink to drain.

Another object of the invention is to provide a foldable stand for attachment to the tip of conventional umbrellas whereby the umbrella may be supported vertically on a golf course or at the doorway of a building whether open or closed. The likelihood of the umbrella being left on a hook, in a stand or on the ground and forgotten by the owner is thus diminished.

A further object of the invention is to provide a portable, foldable stand on an umbrella, formed of material similar to that in a conventional umbrella and devoid of cumbersome parts, the stand being rigid in operative position but conforming to, and embracing the fabric of, the umbrella when in inoperative position.

Still another object of the invention is to provide a light foldable umbrella stand which will clamp on the tip portion of ordinary umbrellas and may thereafter be available to support the umbrella in inverted, vertical, position whenever desired by the umbrella user.

A still further object of the invention is to provide an umbrella with a tripod on the tip portion, the legs of the tripod resiliently and swingably pivoting through the normal folding arc of the umbrella ribs but also swinging further to a fixed, umbrella-supporting, angular position.

Other objects and advantages of the invention will be apparent from the claims, the description of the drawing and from the drawing in which FIG. 1 is a side elevation showing the umbrella stand of the invention accommodating itself to the 'open position of an umbrella.

FIG. 2 is a view similar to FIG. 1 showing the stand accommodating itself to the closed position of an umbrella.

FIG. 3 is a view similar to FIG. 2 showing the umbrella inverted 13nd the stand in operative, umbrella supporting, position.

PEG. 4 is a view similar to FIG. 3 showing the stand supporting an open, inverted umbrella.

FIG. 5 is an enlarged side elevation, partly in section, showing the umbrella stand in umbrella-supporting position in full lines and showing, in dotted lines, the range of inoperative positions of the legs in embracing the fabric of an open or closed umbrella, and

FIG. 6 is a fragmentary view similar to FIG. 5 of a modification.

As shown in the drawing the foldable, portable umbrella stand 20 of the invention may be carried on any conventional umbrella 21, such umbrellas usually having a central rod 22, a handle 23 at one end of the rod and a projecting tip 24 at the other end of the rod. The umbrella 21 also includes ribs 25 pivotally connected to a slotted and grooved ring 2d, a slidable sleeve 27 on the rod 22 and struts 28 pivotally connecting the sleeve 27 to an intermediate part of the ribs. The ribs are covered with a suitable fabric 29 which folds into pleats, as shown in FIGS. 2 and 3, when the umbrella is in closed position and there are suitable spring catches 30 for locking the sleeve on the rod.

3,9l,249 Patented May 28, 1963 Umbrellas, such as 21, are decorative, light and fragile and it will be obvious that while many kinds of cumbersome umbrella stands, of known types, could probably be fixed to the tip 24, the resulting appearance and weight would make it impractical and of little use. No doubt, also means could be built into new umbrellas, as manufactured, which would serve the purpose of an umbrella stand but this would require re-design of umbrella making machinery and be of no assistance to the millions of persons now owning umbrellas. The gist of this invention, therefore, is to provide an umbrella stand which can be easily attached to existing umbrellas and which will be sufiiciently light and fragile in appearance to blend with the design of the umbrella.

Preferably, therefore, the umbrella stand Ztl is formed with a head 32, similar to the grooved slotted ring 26, and with at least three foldable legs 33, 34- and 35 made of material similar to that now used in umbrellas for the ribs 25 and struts 28. As best shown in FIG. 5, the head 32 is annular with a central opening 36, which is preferably an axial bore but could, of course, be a socket capable of accommodating the tip 24, if desired. The inside diameter of the opening 36 is slightly greater than the outside diameter of the conventional umbrella tip and, since such tips vary in diameter, I have found that an inside diameter of about one half inch will accommodate and receive the tip 24 of most umbrellas now in use.

The head 32 of stand 20 includes a plurality of radial slots such as 37 and 38, there being at least three such slots to accommodate at least three legs although more slots and legs can be used if desired. Each leg, such as 33, is formed of extremely light material of tubular or channel cross section, preferably of metal and may be flattened at each end 4% and 41 as well as at an intermediate point 42. The usual umbrella may be several feet in height but the

legs

33, 34 and 35 are preferably only about ten inches in length with the flattened intermediate portion 42 about eight inches from the outer end portion 41 and about two inches from the inner end portion 40. The flattened portions 41} and 41 each contain a

circular aperture

43 and 44, the apertures 43 of the legs receiving an annular wire or spring 45 encircling the head 32 in a peripheral groove 46. Thus the flattened portion of each leg closely fits its radial slot 37 to prevent sidewise movement but the leg is pivotable on the wire to swing in a radial plane relative to the head 32.

As thus far described, the pivotal mounting of the

legs

33, 34 and 35 on the head 3-2 is somewhat similar to conventional umbrella construction. It is essential, in this invention however, that the

radial slots

37 and 38, the shape of the flattened portions 40 and the depth of the groove 46 be such that the legs may freely swing through arcuate paths of about one hundred thirty-five degrees while in an umbrella, the folding arc of the ribs is less than ninety degrees. Thus as shown in full lines in FIG. 5, the

legs

33, 34 and 35, each are swingable in radial planes from an operative position, at about a forty five degree angle from the projected axis of the opening 36, through an angular distance of about one hundred thirtyfive degrees until they are again in substantial parallelism with the said projected axis. The latter position is shown in dotted lines, this being one inoperative position on a closed umbrella. The other inoperative position, on an open umbrella, wherein the legs are nearly in the plane of the slotted, grooved ring, or flange, 45 of head 32 is shown in FIG. 1.

Fastening means 50 is provided on head 32 preferably in the form of an integral collar 51 having a plurality of set screws such as 52 and 53 threaded therearound. A split clamp, of the type used on bicycles, pipes and the like, or any other suitable detachable fastening means, could be fixed to the ring 54 of head 32 for securing the stand 20 to the tip 24 but a collar with set screws on one, or both faces, of the ring 54 is inconspicuous and simple.

-Latehing means 57 is provided on the stand 20 for retaining the

legs

33, 34 and 35 in a predetermined angular relation to the head 32. The latching means is designed to include mechanism for detachably securing the legs, each at about an angle of forty-five degrees, when the stand is operative as an umbrella-supporting tripod as in FIGURES 3, 4 and 5. It is also designed to include mechanism for resiliently retaining the legs in embracing engagement with the fabric 29 of an umbrella, without tearing the fabric, when the device is in inoperative position and while the umbrella is either closed, open or being folded as shown in FIGURES 1 and 2. Latching means 57 includes at least one stop means 58 in the form of an annular flange 59, on head 32 of such outside diameter that it intercepts the edge of the flattened portion 40 of each leg, in the folding path, or are, of the leg, and forms a terminal point for such path. The

legs

33, 34 and 35 are thus prevented from approaching each other further and, in operative position, are each at the same fixed angle. The stop means 58 may include a similar flange on the opposite face of the ring 54, or as illustrated, the collar 51 may also form a stop to the swinging movement of the legs at the opposite ends of their arcuate paths. However, the umbrella 21 itself, serves as an effective stop when the legs are inoperative because the legs rest lightly against the fabric as shown in FIGURES 1 and 2. This is for the reason that the latching means includes an annular spring 61 threaded through the

apertures

43 and 44 of the flattened portions 42 of the

legs

33, 34 and 35. The'spring 61 normally defines a closed circular figure about two inches in diameter and it may be a metal coil spring, a rubber ring or of any other suitable elastomeric material. In the position of the stand 20, shown in FIG. 2 the spring 61 is relaxed but holds the legs against the fabric of the folded umbrella so that they'do not fall outwardly by gravity or during movement of the umbrella. When the umbrella is opened, as in FIG. 1, the spring 61 permits the legs to resiliently open and unfold, the tension of the spring being insufl'icient to cause fracture of the fabric 29 but suflicient to hold the legs against the fabric. Thus in umbrella supported position the'legs of the stand 20 hug the fabric of the umbrella while opening and closing through the folding arc of the ribs.

To place the stand 20 in operative umbrella-supporting position, the user may move one

leg

33, 34 or 35 past the dead centre of the folding path of the legs, whereupon the tension of spring 61 will snap all of the other legs through an additional folding path to the terminal point of thefolding path, at forty-five degrees to the head 32 and to the floor, ground or other support. When the legs are stopped by the flange 59, the spring 61 is under tension and defines a closed triangular figure. when the stand is a. tripod. The triangular figure of the spring may have sides about three or four inches in length which is suflici'ent to maintain the stand 20 as a tripod in: view of the lightness of the umbrella.

It will. be obvious that separate springs could beused in .place of a single annular spring 61 or that various other mechanical equivalents might be used in place of the specific embodiments shown herein.

In any case, the legs are spring loaded toward the folded position of FIG. 2, while in the folding arc of the umbrella ribs, and spring loaded toward the stop flangev 59, when swung slightly beyond that folding are.

As shown in FIG. 6 the portable umbrella stand of the invention may comprise a head 132 having a tip opening 136, radial slots 137 and fastening means 150, all similar to corresponding parts of stand 20. Each leg such as 133 4 a ing slot 143 extending to the inner end portion 140'. A pivotable link 160 connects the intermediate portion 142 to the wire 145 in the annular groove 146, and includes until dead centre is reached. Thereafter the spring enters the recesses 161 and spring loads the legs into the folded position shown in dotted lines. The umbrella 20 is not shown in FIG; 6 for clarity, but it will be apparent that when an umbrella is supported in the device, the inner ends 140 of the legs will bear against the fabric or ribs with the umbrella itself serving as the stop means for the legs. In the inoperative unfolded position, shown in dotted lines, the umbrella can be opened to the position shown in FIG. 1 in which case the spring 157 sim-- ply expands as the legs move outwardly. In this embodiment of the invention the umbrella'is not intended to be opened as in FIG. 4, but must be supported in the folded, or closed, position as in FIG. 3, since the inner ends 140 would tend to pierce the fabric unless the umbrella tip was unusually long.
