A new and improved low cost disposable umbrella in particular one that is suitable for being conveniently stored or arranged in a stack or a vending machine to be dispensed therefrom in the manner that newspapers, shopping bags and the like are dispensed. The umbrella comprises a canopy, a canopy support, handle mechanism and lock mechanism for optionally securing the canopy in an open condition or permitting closing the umbrella. The canopy has a periphery in the form of a closed geometrical figure provided with radial fold lines dividing the canopy into at least one pair of opposed panels and at least two other pairs of opposed panels secured to the first pair of opposed panels. The canopy support is attached to the first pair of opposed panels but not to the other pairs of opposed panels. In the open condition of the umbrella, the canopy support supports the first pair of opposed panels attached thereto and holds the canopy in open condition.

## Background
This invention relates to a disposable umbrella and more particularly to a flat folding umbrella type protector which may be made of inexpensive material such as corrugated board or other planar material such as cardboard and which may be folded, when closed, so that it may be conveniently stored or arranged in a stack and dispensed from an article dispensing machine in the manner that newspapers and shopping bags are dispensed.

Prior to the instant invention, there have been attempts at producing disposable umbrellas from simple planar materials, but such prior devices have not achieved acceptance in the trade and by the consumer because they are awkward to use, or they are too expensive to produce.

The umbrella in accordance with the invention can be made on automatic handling machines having gluing equipment and folding mechanism. The parts or elements of the umbrella are simply die cut. The operation of the disposable umbrella is simple and fool-proof. The umbrella is easy to hold when open, easy to store when closed and operates in a manner in which the comsumer expects it to operate.

FIG. 1 shows an elevational view of the umbrella according to the present invention folded in storage or standby condition;

FIG. 2 is a top plan view of the umbrella in open condition;

FIG. 3 is a bottom plan view of the umbrella in open condition;

FIG. 4 is a view taken along section 4--4 in FIG. 2;

FIG. 5 is a view taken along section 5--5 in FIG. 4;

FIG. 6 shows a view similar to FIG. 1 of an alternative embodiment of the present invention;

FIG. 7 is a view taken along section 7--7 in FIG. 6;

FIG. 8 is a view taken along section 8--8 in FIG. 7;

FIG. 9 shows a view similar to FIG. 4, but of the embodiment of FIG. 6;

FIG. 10 is a view taken along section 10--10 in FIG. 9;

FIG. 11 is a view similar to FIG. 10 showing a variation in structure of the upper end of the handle element;

FIG. 12 is a view in perspective showing details of a locking device; and

FIG. 13 is a view in perspective of the lower portion of a handle.

Referring particularly to the drawings, one embodiment of the invention comprises the umbrella 1, according to FIGS. 1-5 includes a canopy 2 that is a die cut circle having two radial fold lines 18 and four radial fold lines 19, so as to produce two 90.degree. panels 10 and four 45.degree. panels 11 as clearly shown in FIGS. 2 and 3. Umbrella 1 further comprises a one piece canopy support 3 and a handle mechanism 4.

It is significant that the panels 11 are different from the panels 10 as when the umbrella is open, the canopy support 3 cooperates with the canopy 2 to support all of the panels 10 and 11.

The canopy support 3 is a die cut simple planar sheet having a principal central fold line 20 and two principal panels 12 at the ends of which there are provided integral glue flap elements 13 or the like, which as may be seen in FIG. 4 extend under the canopy 2 and are fixedly secured to panels 10 of canopy 2. When it is desired to close the umbrella 1, the locking tabs 21 are pressed inwardly so that they are once more flush with the handle elements 15 and then the canopy support 3 may be lowered by pulling downwardly at fold line 20, for example, to close the umbrella 1 which will take the flat position illustrated in FIG. 1.

As may be seen in FIGS. 3 and 4 the radial fold lines 18 between each pair of the two pairs of panels 11 are generally coplanar with fold line 20 of canopy support 3 whereby as the umbrella 1 is closed, panels 12 of canpopy support 3 will fold downwardly about fold line 20 with portions of panels 11 adjacent to radial fold lines 18 being folded about fold lines 18 and movable inwardly between panels 12 of canopy support 3. The radial fold lines 19 defining one side of each of a panel 10 and a panel 11 of the canopy 2 facilitates folding the panels 11 inwardly therearound and between panels 10 and also the movement of panels 10 together to a folded generally flat condition as illustrated in FIG. 1.

In an alternative embodiment of the present invention according to FIGs. 6-10, the umbrella 1' includes a canopy 2' that is a die cut circle having two radial fold lines 18' and four radial fold lines 19', so as to produce two 90.degree. panels 10' and four 45.degree. panels 11' similar to corresponding elements in the embodiment of FIGS. 2 and 3. Umbrella 1' further comprises a canopy support 3' and a handle mechanism 4'.

The panels 11' of the alternative embodiment are also different from the panels 10' as when the umbrella is open, the canopy support 3' cooperates with the canopy 2' to support all of the panels 10' and 11'.

The canopy support 3' is a die cut simple planar sheet having a principal central fold line 20' and two principal panels 12' at the ends of which there are provided integral glue flaps 13' . As will be apparent from FIG. 9, the canopy support panels 12' support the canopy panels 10' at the location where the glue tabs 13' are secured thereto. The canopy support 3' is otherwise free from contact with the canopy panels 11' as may be seen in FIG. 10, without bearing points as in the embodiment of FIGS. 1-5 and supports canopy panels 11' only through their connection with canopy panels 10'. Thus it will be understood that canopy support 3', which initially is formed of a simple rectangular planar sheet, supports all six panels of the canopy 2' including the two 90.degree. panels 10' and the four 45.degree. panels 11'.

When the canopy 2' of umbrella 1' is open and held erectly with handle mechanism 4' vertically, fold lines 18' are seen to extend above the planes of panels 10 as illustrated in FIGS. 9 and 10.

The canopy support 3' is provided with a central opening 14' through which handle elements 15', 15' of handle mechanism 4' extend. The handle elements 15', 15' at their upper ends, are provided with head extensions 16' and glue tabs 17' which are secured to the canopy as illustrated in the FIG. 9. Note in FIG. 10 that head extension 16' is wider than lower portions of handle element 15' and opening 14' so that upward movement of canopy support 3' is limited thereat. Heat extension 16' thus forms a facsimile T with the rest of handle element 15'.

The canopy support 3' may slide up and down over the handle elements 15', 15' to open and close canopy 2'. Canopy support 3' may be locked in open position by pulling the locking tabs 21', which initially are flush with the handle elements 15', out into the position shown in FIG. 9 so that they extend under the canopy support 3'. It is seen in FIG. 10 that lock tab 21' is generally rectangular and is integral with handle element 15' along a generally vertical hinge portion 23'. When it is desired to close the umbrella 1', the locking tabs 21' are pressed inwardly so that they are once more flush with the handle elements 15' and then the canopy support 3' may be lowered by pulling downwardly at fold line 20', for example, to close the umbrella 1' which will take the flat position illustrated in FIG. 6.

In the collapsed or closed condition of umbrella 1' as illustrated in FIGS. 6-8, canopy panels 10' are disposed on the outside with portions of panels 12' of canopy support 3' sandwiched therebetween, portions of handle elements 15' in turn sandwiched between the said portions of panels 12' and finally canopy panels 11' in turn sandwiched between said portions of handle elements 15". Umbrella 1' may also be reinforced by strips of tape T along various edges as seen in FIGS. 7 and 8.

Other alternative features of the present invention may include a lock key 25' which may be inserted in slots 27' formed in handle elements 15' beneath support panels 12' as illustrated in FIG. 12.

Further, alternative features of the present invention may include the incorporation of reinforcement within the material of handle elements 15' in the form of wires 29', or the like as seen in FIGS. 10 and 13. It is clear that such wires 29' terminate below heads 16' for optimum operatiion. Moreover, instead of the cross bar head 16' to form the letter T with elements 15' as seen in FIG. 10, handle elements 15' may be formed with a head extension 16" having upwardly diverging sides 17" above the opening 14' of canopy support 3'. Also, at the lower end of handle elements 15' a reversely folded portion 31' may be folded to provide a grip which may be secured to the main portion of handle element 15' by taping or by adhesive.

It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
