- the runner device includes a sleeve 01' barrel 22 provided with an outwardly peened lower end to which a protective and strengthening cover 24 is crimped or otherwise attached.
- Sleeve 22 also carries an annular runner crown which is roughly U-shaped in cross section and includes an outer rim portion 25, an inner rim portion 26 and a, connecting portion 28.
- Inner rim portion '28 of the runner crown fits over sleeve 22 in close telescoping engagement and is shown as being held in posiiton between an annular bead or collar 30 on sleeve 22 and the outwardly peened upper end 32 of the sleeve.
- This construction holds the runner crown with its middle portion 28 in the position of a flange extending radiall outward with respect to the sleeve and substantially perpendicular to the length thereof and with runner crown portion 25 in the position of a collar extending upwardly from the outer periphery of flange 28.

- the dotted position to the left of the position in full lines being that assumed by the brace when the runner is near the limit of its downward travel
- the dotted position shown to the right of the position in full lines being that held by the brace when the umbrella is fully extended in use and the runner is at the limit of its upward travel.
- the illustrated device is simple to manufacture and in addition it requires no extra material beyond that initially present in the runner crown, since tabs 35 are composed of the material necessarily displaced from within holes 33 in the formation of these holes and which would otherwise be scrap. It provides rugged construction which readily withstands the severe thrust against the runner, particularly during erection and use of the umbrella when substantially the entire weight of the canopy as well as the force of any wind directed against the upper surface thereof is concentrated at the points of contact between looped brace ends 38 and flange 28 of the runner crown.
- this construction provides for distribution of the thrust over the upper surface of tabs 35 as braces with the actual point of contact between" each looped brace end 38 and tab 35 moving progressively inward as the runner moves upward. Since the strain increases during this motion, the re sult is that its actual point of application to flange 28 moves radially inward and so decreases its leverage on the flange and on the junction between the flange and inner collar 26.
- This construction is accordingly well suited for use with umbrellas oflarge size and under severe service conditions.

6' Claims. (01. 135-28) This invention relates to umbrellas, and particularly to umbrellas of sturdy construction adapted for use on tractors, at the seashore, and other places Where they are subject to rough treatment and severe service conditions.
One of the principal objects of the present invention is to provide a novel runner device of simple and sturdy construction, adapted for use with umbrellas of the above type.
Another object is to provide an umbrella runner having novel reinforcing means which also serve as supporting bearings for the braces of the umbrella ribs.
Other objects and advantages of the invention will be apparent from the following description, the accompanying drawings, and the ap pended claims.
In the drawings, which illustrate a preferred embodiment of the invention, and in which like characters of reference designate like parts throughout- Fig. 1 is an elevational view, partly broken away, illustrating an umbrella provided with a runner embodying the invention;
Fig. '2 is an enlarged section taken substantially on the line 2-2 in Fig. 1;
Fig. 3 is an enlarged vertical section illustrating the operation of the runner; and
Fig. 4 is a further enlarged detail view.
In the drawings, umbrella standard It is preferably composed of steel tubing or other suitable material. The umbrella canopy H is shown as mounted at the upper end of standard In by means of plate 12 and outer cap 14. Notch ring is also secured to the upper end of standard It! and provides pivoted connections for the hooked upper ends of ribs l6. These ribs 16 are in turn supported by braces l8 whose lower ends are pivotally supported by a runner indicated generally at 20, the construction of which is shown in enlarged detail in Figs. 2 to 4.
In the illustrated construction the runner device includes a sleeve 01' barrel 22 provided with an outwardly peened lower end to which a protective and strengthening cover 24 is crimped or otherwise attached. Sleeve 22 also carries an annular runner crown which is roughly U-shaped in cross section and includes an outer rim portion 25, an inner rim portion 26 and a, connecting portion 28. Inner rim portion '28 of the runner crown fits over sleeve 22 in close telescoping engagement and is shown as being held in posiiton between an annular bead or collar 30 on sleeve 22 and the outwardly peened upper end 32 of the sleeve. This construction holds the runner crown with its middle portion 28 in the position of a flange extending radiall outward with respect to the sleeve and substantially perpendicular to the length thereof and with runner crown portion 25 in the position of a collar extending upwardly from the outer periphery of flange 28. This collar portion 25 of the runner crown is preferably inclined inwardly toward the upper end thereof, as shown particularly in Figs. 3 and 4, an angle of the order of 15 from the vertical having been found to give satisfactory results in practice.
In assembling the device, each of the looped ends 38' of rib braces I8 is inserted in its proper hole 33 from the outside, and the end of the brace is preferably flattened as'shown at 40 to facilitate this step. In the subsequent use of the umbrella, each of tabs 35 serves both to reinforce flange '28 and also to provide a bearing which supports brace ends 38 throughout the various positions assumed by the brace in the use of the umbrella. Three of these positions are shown in Fig. 3, the position shown in full lines being an intermediate position assumed during the upward and downward travel of the runner, the dotted position to the left of the position in full lines being that assumed by the brace when the runner is near the limit of its downward travel, and the dotted position shown to the right of the position in full lines being that held by the brace when the umbrella is fully extended in use and the runner is at the limit of its upward travel.
The illustrated device is simple to manufacture and in addition it requires no extra material beyond that initially present in the runner crown, since tabs 35 are composed of the material necessarily displaced from within holes 33 in the formation of these holes and which would otherwise be scrap. It provides rugged construction which readily withstands the severe thrust against the runner, particularly during erection and use of the umbrella when substantially the entire weight of the canopy as well as the force of any wind directed against the upper surface thereof is concentrated at the points of contact between looped brace ends 38 and flange 28 of the runner crown.
Furthermore, this construction provides for distribution of the thrust over the upper surface of tabs 35 as braces with the actual point of contact between" each looped brace end 38 and tab 35 moving progressively inward as the runner moves upward. Since the strain increases during this motion, the re sult is that its actual point of application to flange 28 moves radially inward and so decreases its leverage on the flange and on the junction between the flange and inner collar 26. This construction is accordingly well suited for use with umbrellas oflarge size and under severe service conditions. It is also capable of use with a variety of stop members, one being shown for purposes of illustration as a spring wire 50 coiled about a pin 52 set in standard l and having its end 54 braced against the inside of the standard.
While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
