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.

Review of related technology: U.S. Patent No. 10,441,040 B2 describes an umbrella. The umbrella has a canopy, a main shaft, and a plurality of ribs pivotally attached to the main shaft. Each rib is of adjustable length and includes a pair of outer rib elements. The outer rib elements are flexible and normally adopt a straight configuration aligned with the main shaft in a closed position of the umbrella. In an open position of the umbrella, the outer rib elements flex so that outer ends of the outer rib elements extend generally circumferentially with respect to the canopy. The umbrella can have ribs that would normally be of one piece, in which case accommodation is made for an effective change in the radius of the ribs as the outer rib elements flex.

U.S. Patent No. 10,182,627 B2 describes a sunshade apparatus, such as an umbrella or sunshade, that includes a canopy with extendable portions that may be positioned in a manner so as to maximize shade.

The canopy comprises a material covering supported by flexible ribs and rib extension retainer cords. The umbrella further provides an adjustable strap extending between the exterior distal ends and a handle on one distal end of a flexible collapsible material. The adjustable strap further provides a D-ring and clasp on one end allowing for removal of said strap. Various umbrellas exist. However, their means of operation are substantially different from the present disclosure, as the other inventions fail to solve all the problems taught by the present disclosure.

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 string/restraining 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. Brief Description of the Drawings

An umbrella assembly 100 is described and depicted herein in at least FIG. 1, FIG. 3, and

FIG. 4. As shown in at least FIG. 1, the umbrella assembly 100 generally comprises a canopy component 102, a handle component 108, and a frame component 110. The frame component

110 allows for the containment, storage, protection and mobility of the several components of the umbrella assembly 100, which will be discussed in turn.

The canopy component 102 comprises an interior side 106 disposed opposite an exterior side 104. The exterior side 104 of the canopy component 102 comes into contact with a weather event, such as rain. As such, a material of the canopy component 102 may be a water or weather resistant material, such as a nylon material or a polyester material. Though materials comprising the canopy component 102 have been explicitly listed herein, such listing is for illustrative purposes only and other materials are contemplated.

The frame component 110 is affixed between the canopy component 102 and the handle component 108. The handle component 108 may be of any shape and the handle component 108 is not limited to a curved shape as shown in FIG. 1. In some examples, the handle component

108 may comprise a non-slip material. In other examples, the handle component 108 may comprise a portion of non-slip material.

As shown in FIG. 1 and FIG. 2, the frame component 110 has a first end 116 disposed opposite a second end 118. Moreover, a body portion is located between the first end 116 and the second end 118 of the frame component 110. As shown in various figures, the first end 116 of the frame component 110 flares outward. However, the shape of the frame component 110 is not limited to any particular shape. The first end 116 of the frame component 110 comprises an opening 146. The second end 118 of the frame component 110 engages the handle component

108.

As shown in FIG. 2, the body portion of the frame component 110 includes an inner hollow component 112 surrounded by an outer component 114. The inner hollow component 112 of the frame component 110 is configured to house numerous components that are used for the functioning of the umbrella assembly 100, such as: a spring 122 (of FIG. 3, FIG. 4, FIG. 5, FIG.

6, FIG. 7, and FIG. 8), a set of ribs 128 (of FIG. 1, FIG. 3, FIG. 4, FIG. 5, and FIG. 6), a seat component 134 (of FIG. 3 and FIG. 7), a support rod 140 (of FIG. 1, FIG. 3, and FIG. 9), and/or a base component 152 (of FIG. 3, FIG. 4, FIG. 7, and FIG. 8), among other components not explicitly listed herein. The spring 122 has a first end disposed opposite a second end, where the second end is affixed to the base component 152 proximate the second end 118 of the frame component 110.

The base component 152 is substantially planar in shape and may comprise any geometric shape.

In some examples, the spring 122 is an extension spring. In other examples, the spring 122 is a compression spring. It should be appreciated that the spring 122 may be another type of spring not explicitly listed herein.

Each rib of the set of ribs 128 has a first end disposed opposite a second end. The first end of each rib of the set of ribs 128 is affixed to the interior side 106 of the canopy component

102. The first end of a first subset from the set of ribs 128 are affixed to a first location along a periphery of the interior side 106 of the canopy component 102. Further, the first end of a second subset from the set of ribs 128 are affixed to a second location on the interior side 106 of the canopy component 102. 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 102 as compared to the first location. As such, the second subset from the set of ribs 128 may be shorter in length than the first subset from the set of ribs 128. Further, it should be appreciated that in some examples, the first end of each rib of the set of ribs 128 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

112 of the frame component 110. A material of each rib of the set of ribs 128 may 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 ribs 128) to cause them to arc downwards, the instant invention requires no such string/restraining line. In some examples, the seat component 134 is substantially cylindrical in shape. The seat component 134 has a first side disposed opposite a second side. The first side of the seat component 134 is configured to receive the second end of each rib of the set of ribs 128. The second side of the seat component 134 is affixed to the first end of the spring 122.

The support rod 140 has a first side disposed opposite a second side and is substantially cylindrical in shape. The first side of the support rod 140 is configured to contact the interior side

106 of the canopy component 102. The second side of the support rod 140 contracts the first side of the seat component 134.

A manual mechanism to open and close the umbrella assembly 100 is also described. The outer component 114 of the frame component 110 comprises a knob 148 affixed to a planar portion 150. The planar portion 150 is located perpendicular to the frame component 110. The planar portion 150 is located partially within the inner hollow component 112 and extends to a location outside of the frame component 110.

As shown in FIG. 8, the planar portion 150 is affixed to the seat component 134. Moreover, a force exerted on the knob 148 by the user in a direction away from the handle component 108 (e.g., an upward direction) from a first location 162 to a second location 160 moves each rib of the set of ribs 128 from the closed position within the inner hollow component

112 of the body portion of the frame component 110 to the open position such that each rib of the set of ribs 128 and the canopy component 102 are moved to a location outside of the frame component 110. The open or in-use position of the canopy component 102 may also be referred to as a blooming formation or configuration. It should be appreciated that the force exerted on the knob 148 in the upward direction results in the open position due to the spring 122 being 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 spring 122 from the second location 160 to the first location 162 (e.g., moving each rib of the set of ribs 128 from 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 ribs 128 and the canopy component 102 into the inner hollow component 112 of the body portion of the frame component 110). In fact, the elastic potential energy of the spring 122 draws each rib of the set of ribs 128, as well as the canopy component 102, back into the inner hollow component 112 of the body portion of the frame component 110. 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 spring 122. The elastic potential energy is equal to the work done to stretch the spring 122, which depends upon the spring 122 constant 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 kx 2 . Thus, as shown in FIG. 8, the knob 148 moves 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 ribs 128 is a curved shape, as shown in FIG. 5. Further, in the instant invention, each rib of the set of ribs 128 comprises a bending resistance such that when each rib of the set of ribs 128 is retracted into the inner hollow component 112 of the body portion of the frame component 110, a shape of each rib of the set of ribs 128 moves towards planar shape, as shown in FIG. 6. No pulley or string is needed by the instant invention for each rib of the set of ribs 128 to bend.

In some examples, the knob 148 comprises a lock component (not shown). The lock component may be configured to lock the knob 148 in the open position or in the closed position. In other examples, and as shown in FIG. 9, the second side of the support rod 140 may include a hook component 154. The hook component 154 may be configured to engage the first end of the spring component 122 in 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 in FIG. 10, the body portion of the frame component

110 may comprise one or more openings 156 (or vent holes) disposed therethrough to allow the canopy component 102 to dry when the canopy component 102 is in the closed or non-use position. In some examples, the one or more openings 156 may be randomly spaced. In other examples, the one or more openings 156 may be spaced in a repetitive pattern.
