Abstract
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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0036] The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.
[0037] Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.
[0038] As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
[0039] The phrase “andlor,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
[0040] As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
[0041] It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including,” when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
[0042] An umbrella assembly 100 is described and depicted herein in at least
[0043] 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 oilier materials are contemplated.
[0044] 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
[0045] As shown in
[0046] As shown in
[0047] 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.
[0048] 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 12.8 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] As shown in
[0053] 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.sup.2. Thus, as shown in
[0054] 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
[0055] 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
[0056] 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.
[0057] In some examples, and as shown in
