UMBRELLA ASSEMBLY

An umbrella assembly is described. Manual movement of a knob away from a handle moves each rib and a canopy to a position outside of an inner hollow component of a frame such that the umbrella assembly is in an open and in-use position. In the open and in-use position, a shape of each rib of the set of ribs is curved. Elastic potential energy of a spring located within the inner hollow component of the frame retracts each rib and the canopy into the inner hollow component of the frame. Each rib has a bending resistance such that when each rib is retracted into the inner hollow component of the frame, a shape of each rib moves towards a planar shape.

FIELD OF THE EMBODIMENTS

The field of the invention and its embodiments relate to an improved umbrella assembly.

BACKGROUND OF THE EMBODIMENTS

An umbrella or parasol is a folding canopy supported by wooden or metal ribs that is usually mounted on a wooden, metal, or plastic pole. An umbrella is designed to protect a person against environmental elements, such as rain, snow, or sunlight. Umbrellas may be both portable and stationary. Portable umbrellas may comprise light-weight materials and a minimum amount of structure for ease of transportation. However, such materials may result in the umbrella's moving parts being destroyed when exposed to unpredictable high winds to an extent that the umbrella is no longer usable. Moreover, some umbrellas are difficult to expand into an in-use and open position and to retract into a non-use and stored position. Thus, what is needed is an improved umbrella assembly that is configured to maintain the frame integrity of the umbrella and is also easy for a user to convert from a non-use position to an in-use position.

SUMMARY OF THE EMBODIMENTS

The present invention and its embodiments relate to an improved umbrella assembly.

A first embodiment of the invention describes an umbrella assembly. The umbrella assembly generally comprises a canopy component, a handle component, and a frame component. The canopy component comprises an interior side disposed opposite an exterior side The exterior side of the canopy component comes into contact with an environmental condition, such as rain. As such, a material of the canopy component may be a water or weather resistant material, such as a nylon material or a polyester material.

The frame component of the umbrella assembly is affixed between the canopy component and the handle component. In some examples, the handle component may comprise a non-slip material. In other examples, the handle component may comprise a portion of non-slip material. The frame component has a first end disposed opposite a second end. Moreover, a body portion is located between the first end and the second end of the frame component. The first end of the frame component comprises an opening and the second end of the frame component engages the handle component.

The body portion of the frame component includes an inner hollow component surrounded by an outer component. The inner hollow component of the frame component is configured to house numerous components that are used for the functioning of the umbrella assembly, such as: a spring, a set of ribs, a seat component, a support rod, and/or a base component, among other components not explicitly listed herein.

The spring has a first end disposed opposite a second end, where the second end is affixed to the base component proximate the second end of the frame component. The base component is substantially planar in shape. In some examples, the spring is an extension spring. In other examples, the spring is a compression spring. However, it should be appreciated that the spring is not limited to these examples, as such examples are provided for illustrative purposes only.

Each rib of the set of ribs has a first end disposed opposite a second end. The first end of each rib of the set of ribs is affixed to the interior side of the canopy component. The first end of a first subset from the set of ribs are affixed to a first location along a periphery of the interior side of the canopy component. Further, the first end of a second subset from the set of ribs are affixed to a second location on the interior side of the canopy component. It should be appreciated that the first location differs from the second location. Moreover, the second location is proximate a center of the canopy component as compared to the first location. Further, it should be appreciated that in some examples, the first end of each rib of the set of ribs may be curved in a horn shape (e.g., similar to that of a shoe horn) to allow for easy retraction into the inner hollow component of the frame component. A material of each rib of the set of ribs may be a metal material, a fiberglass material, or a plastic material, among other materials not explicitly listed herein. Unlike traditional systems, the instant invention requires no such stringlrestraini ng line for the set of ribs.

In some examples, the seat component is substantially cylindrical in shape. The seat component has a first side disposed opposite a second side. The first side of the seat component is configured to receive the second end of each rib of the set of ribs. The second side of the seat component is affixed to the first end of the spring.

The support rod has a first side disposed opposite a second side. The first side of the support rod is configured to contact the interior side of the canopy component. The second side of the support rod contracts the first side of the seat component.

A manual mechanism to open and close the umbrella assembly is also described. The outer component of the frame component comprises a knob affixed to a planar portion. The planar portion is located partially within the inner hollow component and extends to a location outside of the frame component. The planar portion is affixed to the seat component such that a force exerted on the knob in a direction away from the handle component (e.g., an upward, direction) moves each rib of the set of ribs from the closed position within the inner hollow component of the body portion of the frame component to the open position at a location outside of the frame component. This movement also brings the canopy component to a position outside of the frame component. An elastic potential energy of the spring retracts each rib of the set of ribs and the canopy component into the inner hollow component of the body portion of the frame component.

In some examples, the knob comprises a lock component that may lock the knob in the open position or the closed position. In other examples, the second side of the support rod may include a hook component that may be configured to engage the first end of the spring component in an event that the lock component becomes accidentally disengaged or fails to function as expected.

In some examples, the body portion of the frame component may comprise one or more openings (or vent holes) disposed therethrough to allow the canopy component to dry.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

An umbrella assembly100is described and depicted herein in at leastFIG. 1,FIG. 3, andFIG. 4, As shown in at leastFIG. 1, the umbrella assembly100generally comprises a canopy component102, a handle component108, and a frame component110. The frame component110allows for the containment, storage, protection and mobility of the several components of the umbrella assembly100, which will be discussed in turn.

The canopy component102comprises an interior side106disposed opposite an exterior side104. The exterior side104of the canopy component102comes into contact with a weather event, such as rain. As such, a material of the canopy component102may be a water or weather resistant material, such as a nylon material or a polyester material. Though materials comprising the canopy component102have been explicitly listed herein, such listing is for illustrative purposes only and oilier materials are contemplated.

The frame component110is affixed between the canopy component102and the handle component108. The handle component108may be of any shape and the handle component108is not limited to a curved shape as shown inFIG. 1. In some examples, the handle component108may comprise a non-slip material. In other examples, the handle component108may comprise a portion of non-slip material.

As shown inFIG. 1andFIG. 2, the frame component110has a first end116disposed opposite a second end118. Moreover, a body portion is located between the first end116and the second end118of the frame component110. As shown in various figures, the first end116of the frame component110flares outward. However, the shape of the frame component110is not limited to any particular shape. The first end116of the frame component110comprises an opening146. The second end118of the frame component110engages the handle component108.

As shown inFIG. 2, the body portion of the frame component110includes an inner hollow component112surrounded by an outer component114. The inner hollow component112of the frame component110is configured to house numerous components that are used for the functioning of the umbrella assembly100, such as: a spring122(ofFIG. 3.FIG. 4,FIG. 5,FIG. 6,FIG. 7, andFIG. 8), a set of ribs128(ofFIG. 1,FIG. 3,FIG. 4,FIG. 5, andFIG. 6), a seat component134(ofFIG. 3andFIG. 7), a support rod140(ofFIG. 1,FIG. 3, andFIG. 9), andlor a base component152(ofFIG. 3,FIG. 4,FIG. 7, andFIG. 8), among other components not explicitly listed herein.

The spring122has a first end disposed opposite a second end, where the second end is affixed to the base component152proximate the second end118of the frame component110. The base component152is substantially planar in shape and may comprise any geometric shape. In some examples, the spring122is an extension spring. In other examples, the spring122is a compression spring. It should be appreciated that the spring122may be another type of spring not explicitly listed herein.

Each rib of the set of ribs128has a first end disposed opposite a second end. The first end of each rib of the set of ribs128is affixed to the interior side106of the canopy component102. The first end of a first subset from the set of ribs128are affixed to a first location along a periphery of the interior side106of the canopy component102, Further, the first end of a second subset from the set of ribs128are affixed to a second location on the interior side106of the canopy component102. It should be appreciated that the first location differs from the second location. Moreover, the second location is proximate a center of the canopy component102as compared to the first location. As such, the second subset from the set of ribs128may be shorter in length than the first subset from the set of ribs128. Further, it should be appreciated that in some examples, the first end of each rib of the set of ribs12.8may be curved in a horn shape (e.g., similar to that of a shoe horn) to allow for easy retraction into the inner hollow component112of the frame component110. A material of each rib of the set of ribs128may be a metal material, a fiberglass material, or a plastic material, among other materials not explicitly listed herein. Unlike traditional systems that require use of a string/'restraining line to pull on the flexible ribs (e.g., the set of ribs128) to cause them to arc downwards, the instant invention requires no such string/restraining line.

In some examples, the seat component134is substantially cylindrical in shape. The seat component134has a first side disposed opposite a second side, The first side of the seat component134is configured to receive the second end of each rib of the set of ribs128. The second side of the seat component134is affixed to the first end of the spring122.

The support rod140has a first side disposed opposite a second side and is substantially cylindrical in shape. The first side of the support rod140is configured to contact the interior side106of the canopy component102. The second side of the support rod140contracts the first side of the seat component134.

A manual mechanism to open and close the umbrella assembly100is also described. The outer component114of the frame component110comprises a knob148affixed to a planar portion150. The planar portion150is located perpendicular to the frame component110, The planar portion150is located partially within the inner hollow component112and extends to a location outside of the frame component110.

As shown inFIG. 8, the planar portion150is affixed to the seat component134. Moreover, a force exerted on the knob148by the user in a direction away from the handle component108(e.g., an upward direction) from a first location162to a second location160moves each rib of the set of ribs128from the closed position within the inner hollow component112of the body portion of the frame component110to the open position such that each rib of the set of ribs128and the canopy component102are moved to a location outside of the frame component110. The open or in-use position of the canopy component102may also be referred to as a blooming formation or configuration. It should be appreciated that the force exerted on the knob148in the upward direction results in the open position due to the spring122being extended.

When a lock component/mechanism is not used or is disengaged, an external force exerted by the user is not needed to bring the spring122from the second location160to the first location162(e.g., moving each rib of the set of ribs128from an open position or an in-use position to a closed position or a non-use position by retracting each rib of the set of ribs128and the canopy component102into the inner hollow component112of the body portion of the frame component110), In fact, the elastic potential energy of the spring122draws each rib of the set of ribs128, as well as the canopy component102, back into the inner hollow component112of the body portion of the frame component110. As described herein, “elastic potential energy,” is potential energy stored as a result of deformation of an elastic object, such as the stretching of the spring122. The elastic potential energy is equal to the work done to stretch the spring122, which depends upon the spring122constant k, as well as the distance stretched. According to Hooke's law, the force required to stretch the spring will be directly proportional to the amount of stretch. The force has the form F=−kx, where the work done to stretch the spring a distance x is Work=½ kx2. Thus, as shown inFIG. 8, the knob148moves a distance “D” between the open and in-use position to the closed and non-use position.

It should be appreciated that typical collapsible/foldable umbrella assemblies are known in the art. However, such systems require use of a string/restraining line to pull on the flexible ribs to cause them to arc downwards, The instant invention requires no such string/restraining line. In fact, in the open and in-use position, a natural shape of the first end of each rib of the set of ribs128is a curved shape, as shown inFIG. 5. Further, in the instant invention, each rib of the set of ribs128comprises a bending resistance such that when each rib of the set of ribs128is retracted into the inner hollow component112of the body portion of the frame component110, a shape of each rib of the set of ribs128moves towards planar shape, as shown inFIG. 6. No pulley or string is needed by the instant invention for each rib of the set of ribs128to bend.

In some examples, the knob148comprises a lock component (not shown). The lock component may be configured to lock the knob148in the open position or in the closed position. In other examples, and as shown inFIG. 9, the second side of the support rod140may include a hook component154. The hook component154may be configured to engage the first end of the spring component122in an event that the lock component becomes accidentally disengaged or fails to function as expected.

Though a manual mechanism has been described, an automatic mechanism may also be used, in some examples, the mechanism may be partially or fully automated.

In some examples, and as shown inFIG. 10, the body portion of the frame component110may comprise one or more openings156(or vent holes) disposed therethrough to allow the canopy component102to dry when the canopy component102is in the closed or non-use position. In some examples, the one or more openings156may be randomly spaced. In other examples, the one or more openings156may be spaced in a repetitive pattern.
