Definitions

  • the present invention is directed to an umbrella of the type commonly used outdoors, and in particular, to the type adapted to include an enlarged canopy and associated frame assembly in order to provide an optimum shaded area or otherwise protected area beneath the umbrella.
  • the umbrella assembly is structured to have an automatically variable length depending on whether the umbrella is in either an expanded position or a collapsed position. When disposed in the collapsed position, the feature ensures that interference between the enlarged canopy and/or supporting portion of the frame assembly and any object surrounding the base of the umbrella is avoided.
  • Umbrellas of various types, sizes and configurations have been used and continue to be used extensively for a variety of different utilitarian and recreational activities. Perhaps most common is a portable umbrella which is typically handheld and utilized to protect an individual from adverse whether conditions, and most often rain. Handheld umbrellas are generally light-weight but of durable construction to facilitate being carried around by an individual user. The functional or operational components of such known umbrella structures are such as to render them quickly and easily positioned between collapsed position, convenient for storage purposes, and an expanded position, wherein the expanded umbrella canopy overlies and shelters the user from rain, sun, etc.
  • umbrellas are primarily designed for recreational use. These are generally large, upstanding umbrellas commonly found at outdoor public locations such as (but not limited to) restaurants, sidewalk cafes, hotels, around swimming pools, and a variety of other areas that cater to the outdoor congregation of a plurality of people. As such, these larger outdoor umbrellas are primarily structured to shield individuals from the sun, and possibly from other environmental conditions such as wind, light rain, etc. With regard to providing shade from the sun, it is understood that due to the earth's rotation, the sun's rays can be directed throughout the day at more than one angle, and in some cases, it may be desirable to shift or otherwise angle the umbrella's canopy so as to offer an adequate amount of shade in response.
  • umbrellas are also typically structured to endure relatively harsh weather conditions, including consistent and repeated exposure to the sun's rays.
  • these larger outdoor umbrellas can be exposed to high winds, such as those associated with an unexpected storm, etc.
  • umbrellas intended for outdoor use should possess sufficient structural integrity and other features to address these situations, including being capable of extended use, and even under such harsh conditions.
  • they should also be structured to permitting them to be relatively easily moved between the expanded and collapsed position, and ideally, should also include some structure for permitting them to be moved or rolled to another location for storage, such as for safe-keeping when not in use, etc.
  • one of the primary functional features of large, outdoor umbrellas is the ability to provide shade to a significantly large area. Therefore, in order to optimize the shaded area, at least in terms of dimension, there is an increased demand for outdoor umbrellas which have a canopy and accompanying plurality of supporting ribs of significantly greater size. Clearly, the larger sized canopy produces a larger shaded area.
  • many umbrellas, including those that provide a larger shaded and/or sheltered area are frequently used in combination with tables, chairs or other seating facilities and/or a variety of other structures, in order that individuals may enjoy a protected area offered by the umbrella for extended periods.
  • one area of concern involves the physical interference of the outer peripheral portions of the extended size canopy (and/or supporting structure associated with the canopy) with any one or more objects placed beneath or in the adjacent vicinity of the umbrella, such as a table or chair, as the umbrella is closed into its collapsed position.
  • Such physical interference is a common occurrence, especially when the size of the canopy necessitates the dimensioning of the supporting rib structure being almost equal in length to that of the supporting pole or stanchion which is a necessary part of the frame assembly.
  • supporting poles or stanchions of extended length provide additional problems.
  • the positioning of the canopy may then be at too great a distance above the table or other supporting surface to be aesthetically pleasing and/or to provide meaningful shade or shelter of the intended area there-beneath.
  • umbrellas having extended length support poles or stanchions encounter significant instability problems in situations where they are subjected even to mild wind conditions.
  • the present invention is intended to present a solution to the above described needs and others which remain in this field of art.
  • the present invention is directed to an umbrella of the type which is typically, but not exclusively, used outdoors for providing shade or other shelter to a given area.
  • an umbrella of the type which is typically, but not exclusively, used outdoors for providing shade or other shelter to a given area.
  • such outdoor umbrellas are of a sufficient size to establish a desired protected or shaded area.
  • the present invention is more specifically directed to an umbrella and an accompanying frame assembly which overcomes known disadvantages and problems associated with the use of umbrellas having an increased size canopy and supporting rib structure.
  • the umbrella assembly of the present invention incorporates structural and operational features which provide for the substantially automatic variance of the height or longitudinal dimension of a supporting stanchion assembly.
  • the length of the stanchion assembly is adjusted or changed in order that the perimeter of the canopy and/or the outer, free ends of the supporting ribs are raised a sufficient distance above a supporting surface to prevent their interference with objects in the vicinity of the base of the stanchion.
  • a preferred embodiment of the umbrella assembly of the present invention includes a frame which incorporates the aforementioned stanchion assembly.
  • the stanchion assembly is operatively disposed in a vertically upright or otherwise generally upstanding orientation relative to the ground or other supporting surface on which it is positioned. It is recognized as common practice to surround the base of the stanchion with a table or a variety of other objects which facilitate the use of the shaded or protected area beneath the umbrella. As such, the stanchion may even be at least partially supported by the table as it extends upwardly therefrom a sufficient distance for positioning of a canopy at a predetermined and desired height above the shaded or protected area.
  • the frame assembly of the present invention also includes a plurality of ribs having an inner end pivotally or otherwise movably connected to an outer or upper end of the stanchion, normally by means of a connecting hub. When in an expanded position, the plurality of ribs extend outwardly therefrom in supporting relation to a canopy positioned exteriorly of the ribs.
  • at least one preferred embodiment of the frame assembly of the present invention includes a plurality of struts having an inner most end pivotally or otherwise movably connected to a main hub. The outer end of each of the struts is pivotally or otherwise movably attached at a fixed location along the length of a corresponding one of the plurality of ribs.
  • a positioning assembly is mounted on the stanchion assembly in direct association with the main hub, the plurality of struts and the plurality of ribs.
  • the positioning assembly is operable to selectively dispose the umbrella between the expanded position and a collapsed position.
  • the plurality of ribs depend downwardly from the upper end or portion of the stanchion assembly in somewhat surrounding relation and along at lest a majority of the length of the stanchion assembly.
  • the stanchion assembly of various preferred embodiments of the present invention is structured to include an automatically adjustable and/or variable longitudinal dimension, dependent on whether the umbrella is in the extended position or the collapsed.
  • the stanchion assembly includes an adjustment assembly associated therewith.
  • the adjustment assembly may be more specifically defined as a biasing mechanism which serves to raise or outwardly extend an upper portion of the stanchion assembly from a remaining portion thereof, in order that the canopy and supporting rib structure also be raised a greater distance from the supporting surface on which the umbrella rests.
  • the stanchion assembly comprises a first portion generally comprising a majority of the length of the stanchion assembly extending upwardly from the supporting surface on which the umbrella is positioned.
  • a second portion of the stanchion assembly is defined by an upper end or upper portion thereof which is separable from the first portion of the stanchion assembly.
  • the plurality of supporting ribs and the canopy secured thereto is mounted on the second portion of the stanchion assembly and movable therewith relative to the first portion as well as the supporting surface on which the umbrella is mounted.
  • the adjustment assembly and/or biasing mechanism is interconnected in at least partially supporting relation between the first and second portions of the stanchion assembly.
  • various preferred embodiments of the present invention may include the biasing mechanism being fluid activated, and even more specifically, embodied in the form of a pneumatic spring or fluid activated piston and cylinder assembly.
  • at least one additional preferred embodiment of the present invention could include a mechanical type basing mechanism operatively interconnected between the first and second portions of the stanchion assembly. If utilized, the mechanical biasing mechanism would be structured to raise the second portion, the canopy and the plurality of supporting ribs associated therewith, as the umbrella is selectively disposed into the collapsed position.

  • the present invention is directed to an umbrella assembly, generally indicated as 10 , and in particular, to a frame assembly generally indicated as 12 and associated therewith.
  • a canopy secured to the frame assembly 12 in a somewhat conventional manner, dependent on the specific structural features of the canopy.
  • the canopy is preferably formed from an at least partially flexible material so as to facilitate its positioning, along with other attendant portions of the frame assembly 12 , between an outwardly extended or expanded position and a somewhat downwardly depending collapsed position.
  • the canopy can be formed from a variety of different materials, dependent at least in part on the particular application for which the umbrella 10 is intended. In any event, the canopy material should be such as to provide shade from the sun as well as shelter from other weather conditions.
  • the umbrella 10 and the frame assembly 12 include a stanchion assembly, generally indicated as 14 .
  • the stanchion assembly 14 when disposed in an operable position, normally assumes a vertical or at least substantially upstanding position, as shown.
  • the lower end 16 of the stanchion assembly 14 is connected to or otherwise associated with a supportive base 18 .
  • the base 18 typically is disposed on a supporting surface 20 , which may be a ground surface, deck, or a variety of other support structures representative of the area for location where the umbrella 10 is used.
  • the umbrella 10 and in particular, the frame assembly 12 further includes a first or main hub structure 22 movably connected to the stanchion 12 so as to move along at least a portion of the length thereof as the umbrella 10 and frame assembly 12 are disposed between the fully extended position of FIG. 1 and the collapsed position of FIG. 3 .
  • a second hub structure 24 is also secured to the stanchion 14 adjacent an upper end thereof as disclosed. The second hub 24 functionally differs from the first hub 22 by being connected or attached in a substantially fixed location adjacent the upper portion of the stanchion assembly 14 .
  • both the first and second hubs 22 and 24 may be rotatable about the central axis of the stanchion assembly 14 if, for example, it is desirable to rotate or reorient the canopy portion of the umbrella. It is also emphasized that while the specific structural features of the first and second hubs 22 and 24 may vary, possible embodiments thereof are substantially equivalent to the hub structures disclosed in U.S. Pat. No. 6,314,976 issued to the inventor herein, which patent is incorporated herein in its entirety by reference.
  • Additional structural features of the frame assembly 12 include a plurality of ribs 26 having one end pivotally or otherwise movably interconnected to the upper portions of the stanchion assembly 14 such as by being pivotally attached to the second hub 24 .
  • the ribs 26 may vary in number and serve as the primary structure for the mounting and support of the aforementioned canopy structure.
  • the canopy structure is movable with the plurality of ribs 26 as the umbrella 10 and frame assembly 12 are selectively positioned between the expanded position of FIG. 1 and the collapsed position of FIG. 3 .
  • FIG. 10 Yet additional structural features of the frame assembly 10 include a plurality of struts 28 which are preferably equal in number to the plurality of ribs 26 .
  • Each of the struts 28 have an inner end as at 28 ′ pivotally or otherwise movably connected to the first hub 22 and movable therewith along the length of the stanchion 14 as the umbrella 10 and frame assembly 12 are disposed between the expanded and collapsed positions.
  • the outer ends 28 ′ of each of the struts 20 are pivotally or otherwise movably connected to a correspondingly position one of the plurality of ribs 26 as schematically represented in FIGS. 1-3 and shown in more detail in FIGS. 7 and 8 .
  • the struts 28 When the struts 28 are disposed in the collapsed position of FIG. 3 they substantially surround the exterior of the stanchion 14 and are located on the interior of the plurality of ribs 26 , depending downwardly from the hub 24 and/or the upper end of the stanchion.
  • distinguishing features of the umbrella 10 as well as the frame assembly 12 include the relatively long, extended length of each of the ribs 26 .
  • a canopy structure connected to and supported by the ribs 26 when in the expanded position of FIG. 1 has a relatively enlarged or significantly increased diameter from that normally found with conventional outdoor, shade umbrellas.
  • the shaded area provided by the umbrella 10 can be greatly increased by extending the size of the canopy carried by the frame assembly 10 .
  • the provision of an enlarged canopy requires the structuring of the plurality of support ribs 26 to have an extended or enlarged length.
  • certain problems and/or disadvantages evolve relating to the operation of the umbrella 10 and frame assembly 12 , as described previously herein.
  • the umbrella 10 and frame assembly 12 is represented in a fully expanded position.
  • movement of the ribs 26 to a collapsed or closed position utilizing a conventional stanchion or center, support pole would result in the outer ends 26 ′ of the ribs 26 , as well as the periphery of a canopy supported thereon, extending downwardly to a location on the stanchion assembly 14 indicated as 100 .
  • the path of travel of the outer ends of the ribs 26 utilizing a conventional fixed length stanchion assembly 14 , is schematically represented by the directional arrows 102 presented in phantom.
  • the ribs 26 being of extended length, would be disposed along the length of a conventional, fixed length stanchion to a point very close to the supporting base 18 and/or supporting surface 20 .
  • This positioning of the ends 26 ′ at the location 100 relative to the supporting surface 20 would result in the inability to place any type of table, seating arrangement or other objects in the immediate vicinity of the supporting base 18 and/or support surface 20 .
  • tables, chairs, and a variety of other objects are commonly associated with outdoor umbrellas, and in fact, may be specifically structured to surround and/or engage a lower portion of a support pole or stanchion. Provision of such accommodating structures, such as a table, would be impractical for use with a conventional outdoor umbrella having a plurality of ribs of extended length and supporting a canopy of an extended diameter.
  • one feature of the present invention is the provision of an umbrella 10 , and in particular, a frame assembly 12 having a variable height or longitudinal dimension dependent on whether the umbrella is in the expanded position of FIG. 1 or the collapsed position of FIG. 3 .
  • the stanchion assembly 14 of the present invention is specifically structured to have its height, when in an operable position, increased or decreased dependent upon whether the umbrella 10 and frame assembly 12 is in the aforementioned expanded or collapsed positions.
  • This functional height may, of course, vary.
  • the stanchion assembly 14 is structured to have its length, or height automatically varied to substantially correspond to the proper or functional height, as set forth above.
  • the stanchion assembly 14 includes a first portion 40 which has an elongated configuration and which extends along preferably a majority a length of the stanchion 14 between its opposite ends.
  • the first portion of the stanchion 40 includes an at least partially hollow interior and may be generally defined by a tubular construction of the type well known in the umbrella industry.
  • the stanchion assembly 14 further comprises a second portion 42 which is coaxially disposed to the first portion 40 and which is separable therefrom as represented in FIGS. 2, 3 , 5 , 6 and 8 .
  • the second portion 42 may comprise a shorter longitudinal dimension than the first portion and defines the upper portion of the stanchion assembly 14 to which a plurality of ribs 26 are connected.
  • the plurality ribs 26 move with the second portion 42 and are raised or extended coaxially outwardly from the first portion 40 .
  • This outward extension or raising of the second portion 42 relative to the first portion 40 serves to increase the height or longitudinal dimension of the stanchion assembly 14 while concurrently raising the plurality of ribs 26 to the position demonstrated in FIG. 3 , when the umbrella 10 and frame assembly 12 are disposed in the collapsed position.
  • the outward extension of the second portion 42 relative to the first portion 40 serves to extend the length of the stanchion 14 and position the plurality of ribs 26 and free ends 26 ′ upwardly, a significantly greater distance from the support surface 20 and support base 18 .
  • the adjustment assembly preferably comprises a biasing mechanism which, in a most preferred embodiment, comprises a fluid activated biasing structure such as, but not limited to, a pneumatic spring and/or a fluid activated cylinder and piston assembly.
  • the biasing mechanism comprises a cylinder and piston assembly including a cylinder 50 fixedly secured on the interior of the stanchion 14 and more specifically on the interior of the first portion 40 of the stanchion assembly 14 .
  • a piston 52 is cooperatively structured with and movable relative to the cylinder 50 and is disposed, at least partially, on the interior of the second portion 42 of the stanchion assembly 14 .
  • sleeves 56 and 58 are disposed in concentric, surrounding relation to portions of the cylinder 50 and the piston 52 respectively.
  • the cylinder and piston assembly 50 and 52 is activated by air or other fluid. As such, when the umbrella 10 and frame assembly 12 are in the extended position of FIGS. 1, 4 and 7 , the cylinder and piston assembly 50 , 52 are in a compressed position and as such exert an outwardly directed, separating, biasing force on the second portion 42 .
  • the biasing force exerted by the cylinder and piston assembly 50 , 52 serves to separate and extend the second portion 42 outwardly from the first portion 40 of the stanchion assembly 14 , as schematically represented by directional arrow 60 .
  • This serves to extend or lengthen the longitudinal dimension of the stanchion assembly 14 while concurrently raising the plurality of ribs 26 and a canopy structure supported thereon.
  • the piston 52 extends outwardly from the cylinder 50 a maximum or predetermined distance so as to separate the second portion 42 from the first portion 40 a predetermined or maximum distance.
  • This will position the plurality of ribs 26 and any canopy structure supported thereon a sufficiently spaced distance from the supporting surface 20 on which the umbrella 10 is positioned, to provide adequate space between the free outer ends 26 ′ of the plurality of ribs 26 and the supporting surface 20 . Adequate room will thereby be provided to prevent any contact or other interference with the plurality of ribs 26 and any table, seating assembly or other objects in the vicinity of the lower portion of the stanchion 14 and/or base 18 .
  • the structural specifications of the cylinder and piston assembly 50 , 52 may vary, it is intended that the biasing force produced thereby and exerted on the second portion 42 is sufficient to cause the intended separation, while concurrently serving to at least partially support the plurality of ribs 26 and a canopy structure thereon in the outwardly extended position, while the umbrella 10 is collapsed.
  • this outwardly directed and supporting force of the cylinder and piston assembly 50 , 52 may be overcome with minimal effort, when it is desired to dispose the umbrella 10 in the aforementioned outer, expanded position of FIG. 1 .
  • positioning assembly may take the form of a pulley and cable assembly appropriately interconnected to the stanchion assembly 14 and more specifically to the first and second portion 40 and 42 and/or the hubs 22 and 24 mounted thereon.
  • the exertion of a pulling force on a positioning cable will result in downward travel of the second portion 42 relative to the first portion 40 against the biasing force exerted thereon by the adjustment assembly 46 until the first and second portions are disposed in contact and/or supporting engagement with one another as clearly demonstrated in FIGS. 1, 4 and 7 .
  • the positioning line associated with the aforementioned pulleys may be locked into position by a gripping cleat of the type known in the industry.
  • the biasing force of the adjustment assembly 46 will be dominant and serve to raise the second portion 42 from the first portion 40 and thereby extend the longitudinal dimension of the stanchion assembly 14 .
  • the plurality of supporting ribs 26 and any canopy structure supported thereon will be raised so as to provide adequate spacing between the free ends 26 ′ of the plurality of ribs 26 and the supporting surface 20 , as described in detail above.
