Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/882,360, filed Dec. 28, 2006, the entirety of which is hereby incorporated herein by reference for all purposes.
- The present invention relates generally to umbrellas and more particularly, to collapsible umbrellas.
- Collapsible umbrellas have been known for a substantial period of time. The advantage of collapsible umbrellas over the non-collapsible types is that collapsible umbrellas can provide cover for the user when needed, but can be quickly collapsed for storage or non-use. Generally, collapsible umbrellas have a plurality of support arms to support an umbrella canopy, which is used to protect a user from rain, snow, or other weather elements. The support arms are generally hinged in one or more locations to render the support arms and canopy collapsible. A typical collapsible umbrella can be seen in
FIGS. 1-4 . As best seen inFIGS. 3-4 , the top surface of the umbrella, which is the surface that is exposed to rain or other elements when in use, is exposed to the user when the umbrella is in a collapsed configuration. Because the top surface of the umbrella is generally exposed to a user when collapsed, water often splashes onto the user, the user's clothes, or leaks onto surrounding items, such as car floorboards, flooring, etc. - Thus it can be seen that a need exists for improvements to collapsible umbrellas to provide for an umbrella that permits a user to collapse the umbrella without getting wet. It is to the provision of this need and others that the present patent application is directed.
- In one aspect, the present invention is a collapsible umbrella including a canopy having a top side and a bottom side. The umbrella is capable of being manipulated between an open position and a closed position. The top side of the canopy is substantially exposed when the umbrella is in the open position, and only the bottom side of the canopy is substantially exposed when the umbrella is in the closed position.
- In another aspect, the present invention is a collapsible umbrella including a canopy, a central support shaft, a plurality of support braces, and a sliding carriage attached to the central support shaft. The canopy has a top side and a bottom side. The support braces are coupled to the canopy and the sliding carriage. User operation of the sliding carriage along the central support shaft manipulates the umbrella between an open configuration and a closed configuration. The top side and bottom side of the canopy are substantially exposed when the umbrella is in the open configuration, and the top side is substantially enclosed when the umbrella is in the closed configuration.
- These and other aspects, features and advantages of the invention will be understood with reference to the drawing figures and detailed description herein, and will be realized by means of the various elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following brief description of the drawings and detailed description of the invention are exemplary and explanatory of preferred embodiments of the invention, and are not restrictive of the invention, as claimed.

It is to be understood that this invention is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed invention. Also, as used in the specification including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment.
- With reference now to the drawing figures, a typical
collapsible umbrella 10 can be seen inFIGS. 1-4 . Generally, a known collapsible umbrella includes acanopy 20, acentral support shaft 30, a slidingcarriage 40, and a plurality of hingedsupport braces 50. Thecanopy 20 has atop surface 22, which is directly exposed to the elements, and abottom surface 24. When theumbrella 10 is in the open position, as best seen inFIG. 1 , thecanopy 20 is stretched over thesupport braces 50, providing cover for a user of the umbrella from rain, sleet, snow, sun exposure, etc. When a user has finished utilizing the umbrella and wishes to close it for storage, entry into a vehicle or building, or for any other reason, a user may collapse theumbrella 10 as seen inFIG. 3 . Typically, to close theumbrella 10, a user may slide thecarriage 40 along thesupport shaft 30 in the direction away from thecanopy 20. When thecarriage 40 is moved vertically away from thecanopy 20, thesupport braces 50, which are generally connected to both thecanopy 20 and to thecarriage 40, slide vertically with the carriage causing thecanopy 20 to collapse and fold into partitions. To aid in the collapse of thecanopy 20, thesupport braces 50 usually have one ormore hinges 52 that permit the braces to bend into two or more pieces, as best seen inFIG. 4 . Optionally, thesupport shaft 30 is telescoping to further minimize the size of a closedcollapsible umbrella 10. A typicalcollapsible umbrella 10 may also include a handle 60 for user ease in holding the umbrella during use. - As detailed above, a typical
collapsible umbrella 10 can be very convenient for a user because of its ability to provide cover for a user during inclement weather, while permitting a user to collapse the umbrella into a fraction of the size for storage. However, a drawback to thecollapsible umbrella 10 is that when a user utilizes the umbrella for cover against rain, it is likely that the user will get wet when trying to collapse the rain soakedumbrella canopy 20. The user is likely to get wet because thetop surface 22 of the canopy can harbor a substantial amount of water immediately after use, and the water is often directed towards the user or other surroundings when theumbrella 10 is closed. This occurs because thetop surface 22 of theumbrella 10 is exposed when the umbrella is either in the open or closed position. - The
collapsible umbrella 110 of the present invention avoids the above listed deficiencies of the typicalcollapsible umbrella 10 and dramatically reduces the amount of water that a user may contact when using. In reference toFIGS. 5-6 , acollapsible umbrella 110 according to a first example embodiment of the present invention is depicted, having acanopy 120, acentral support shaft 130, asliding carriage 140, a plurality of support braces 150 (not shown), and ahandle 160. The canopy can be described as including atop surface 122 and abottom surface 124. Uniquely, thecollapsible umbrella 110 of the present invention permits a user to close thecanopy 120 of the umbrella in the opposite direction from typicalcollapsible umbrellas 10, such that the canopy is reversed upon closing, as best seen inFIG. 6 . It can be seen that while thetop surface 122 of thecanopy 120 is exposed to the elements when in use, thebottom surface 124 becomes the surface that is exposed to the user and surroundings when in the closed position. Because water that remains in connection with thecanopy 120 after use by a user typically resides only on thetop surface 122 of the canopy, thebottom surface 124 is generally dry. By enabling a user to close theumbrella 110 such that thebottom surface 124 is exposed, a user is thus able to interact with exposed areas of the umbrella without getting wet. Additionally, a user is able to better direct/shake the accumulated water from thetop surface 122 of thecanopy 120 by holding theumbrella 110 upside down and permitting the water to drain away from the user. - In another example embodiment of the present invention, a user can collapse the
umbrella 110 into thehandle 160 such that little or no part of thecanopy 120 is exposed when the umbrella is in the closed position, as shown inFIG. 7 . In alternate embodiments, thehandle 160 can include means for enclosing thecanopy 120 within, such as with Velcro®, one or more zippers, a waterproof cover, etc. - In still another example embodiment of the present invention, the
umbrella 110 can collapse into foldable sections to minimize the size of the umbrella when closed, as best seen inFIG. 8 . In such an embodiment, the support braces 150 have multiple joints to permit two or more folds in thecanopy 120. Such an embodiment allows theumbrella 110 to collapse into a more vertically compact position for storage or non-use. This embodiment will be described in greater detail below. - With reference now to
FIG. 9 , an example embodiment depicting acollapsible umbrella 110 is shown without acanopy 120 for clarity. It can be seen that the support braces 150 further comprise two sections: alower section 155, and anupper section 156 and are coupled to each other through ahinge 152. The distal end of thelower section 155 is connected to thecentral support shaft 130 with a cable, wire, orstring 170, which provides stability and support for thebrace 150 andcanopy 120 when theumbrella 110 is in the open position. The base end of thelower section 155 is directly coupled to the slidingcarriage 140. Theupper section 156 is connected to the slidingcarriage 140 with asecond wire 172, which rotates the upper section of thesupport brace 150 vertically when theumbrella 110 is being closed. Thewire 172 is preferably connected to the distal end of theupper section 156, although it is not necessary, and preferably connects to thecarriage 140 through the interior of thecentral support shaft 130 as seen inFIG. 9 . In alternate embodiments, thewire 172 connects theupper section 156 to thecarriage 140 via the exterior of thesupport shaft 130. -
FIGS. 10-13 further depict an example embodiment of the present invention in operation. When a user wishes to close theumbrella 110, the user can slide thecarriage 140 along thecentral support shaft 130 towards thehandle 160. In doing so, the carriage moves thelower sections 155 of the support braces 150 into a substantially vertical position as seen inFIGS. 11-13 . At the same time, as the slidingcarriage 140 is moved towards thehandle 160, thewires 172 rotate theupper sections 156 of thebraces 150 towards a vertical position exposing the bottom side of thecanopy 120. As the slidingcarriage 140 vertically traverses thecentral shaft 130 towards thehandle 160, the central shaft can telescopically be compacted as best seen inFIG. 13 .FIG. 6 depicts a similar embodiment shown with thecanopy 120 included. - Another example embodiment of the present invention is seen in
FIGS. 14-16 . Having many of the same features as theprevious example umbrella 110, this embodiment is different it that it has two ormore hinges 152 in the support braces 150, creating alower section 155, anupper section 156, and anintermediate section 157. Because of the multiple hinges, thebraces 150 and thecanopy 120 are collapsible into a plurality of sections, minimizing the vertical height of thecollapsed umbrella 110 while still exposing thebottom side 124 of the canopy to the user when the umbrella is closed.FIG. 8 depicts a similar embodiment shown with thecanopy 120 included. - It should be noted that there are numerous additional mechanical configurations that can be utilized to achieve a collapsible umbrella according to the present invention and the present invention is not limited to the configurations presented herein. For example, the distal ends of the support arms can include magnetic tips to keep the support arms together when umbrellas according to example embodiments of the present invention are in the collapsed position.
- While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
