Full Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an adjustable mounting device for securing an umbrella to a stroller, carriage, pram, walker, wheelchair or other such device to provide protection from environmental conditions to an individual pushing the device, without requiring use of a hand to hold the umbrella. 
     2. Description of Related Art 
     Baby strollers often come equipped with canopies and rain covers that protect the child from environmental conditions such as sun and rain. The person pushing the stroller, hereinafter referred to as “a user”, however, is not provided such protection and as such often must hold an umbrella separately, in addition to pushing the stroller. Due to size and other design characteristics, many strollers require two hands to steer properly, so a rainstorm or other such event can provide a frustrating experience to the parent or other individual wheeling the stroller through inclement weather. 
     Other patents have discussed mechanisms for attaching an umbrella or parasol to a baby carriage or stroller. For example, U.S. Pat. No. 7,493,908 (Carter) relates to an umbrella anchored to a stroller by a guy line or guy lines, belt or buckle. Such method of attachment does not address the critical problem of keeping the umbrella stable and upright while in motion. Such method also does not effectively take into account the direction of the rain or the height of the user. 
     U.S. Pat. No. 6,244,557 (Maze) relates to a bridging mechanism to attach to two spaced handlebars of a stroller. The application of such mechanism is very limited. For example, the mechanism is not useable on the multitude of strollers that contain a single handlebar, does not permit maneuverability of the umbrella, and does not allow for stow-ability on the stroller. 
     U.S. Pat. No. 4,919,379 (Goetz) relates to a clamping fixture for attaching umbrellas, parasols, sunscreens and the like to baby carriages or strollers. Such device is intended exclusively to protect the child seated in the stroller and does not address the problem of keeping the user dry in a rainstorm, or the awkwardness of trying to push a stroller on a rainy day, while holding an umbrella. Such device also does not provide adjustability for position or height. 
     Accordingly, there is room for improvement in mechanisms for providing an umbrella to a user of a stroller. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of umbrella holding methods now present in the prior art, the present invention provides a new umbrella mounting device for a stroller wherein the same can be utilized for protecting the user of a stroller from inclement weather. 
     In one embodiment of the invention, an umbrella assembly for providing cover to a user pushing a stroller or similar device is provided. The assembly includes a clamp mechanism structured to be coupled to a portion of the stroller and an umbrella portion selectively coupled to the clamp mechanism. The umbrella portion is selectively rotatable relative to the clamp mechanism among a plurality of positions. 
     The umbrella portion may be moveable among the plurality of positions while coupled to the clamp. The plurality of positions may comprise a first position in which the umbrella is structured to be positioned generally above the user and a second position in which the umbrella portion has been rotated about 180° downward from the first position. The clamp mechanism may comprise a first knob and a second knob, the first knob being structured to tighten or loosen the clamp mechanism from the stroller and the second knob being disposed to adjust the coupling of the umbrella portion and the clamp member. The umbrella portion may comprise a telescoping shaft having a lower portion and an upper portion, the lower portion having a number of apertures disposed therein and the upper portion having a button member protruding radially therefrom. The button member may be structured to selectively engage a selected one of the number of apertures in a manner that allows for the relative positioning of the lower portion and the upper portion to be selectively adjusted. 
     In another embodiment of the invention, another umbrella assembly for providing cover to a user pushing a stroller or similar device is also provided. The assembly includes an umbrella having a shaft extending therefrom and a clamp mechanism having a first portion structured to be coupled to a portion of the stroller and a second portion coupled to the shaft of the umbrella. The second portion of the clamp mechanism is selectively rotatable about the first portion of the clamp mechanism such that the umbrella may be placed among a plurality of positions. 
     The second portion of the clamp mechanism may be selectively rotatable with respect to the first portion of the clamp mechanism from a first position to a second position about 180 degrees from the first position. The first portion of the clamp mechanism may comprise a first knob that is structured to tighten or loosen the coupling of the first portion and the portion of the stroller. The second portion of the clamp mechanism may comprise a second knob member that is structured to control rotation of the second portion about the first portion. The second portion of the clamp mechanism may comprise a hollow shaft that slidably engages the shaft of the umbrella. The hollow shaft may comprise a number of apertures disposed therein and the shaft of the umbrella may comprise a button member protruding radially therefrom, the button member being structured to selectively engage a selected one of the number of apertures in a manner that allows for the relative positioning of the shaft of the umbrella within the hollow shaft of the second portion to be selectively adjusted.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As used herein, the singular form of “a”, “an”, and “the” include plural references unless the context clearly dictates otherwise. As used herein, the statement that two or more parts or components are “coupled” shall mean that the parts are joined or operate together either directly or indirectly, i.e., through one or more intermediate parts or components, so long as a link occurs. As used herein, “directly coupled” means that two elements are directly in contact with each other. As used herein, “fixedly coupled” or “fixed” means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other. 
     As used herein, the word “unitary” means a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a “unitary” component or body. As employed herein, the statement that two or more parts or components “engage” one another shall mean that the parts exert a force against one another either directly or through one or more intermediate parts or components. As employed herein, the term “number” shall mean one or an integer greater than one (i.e., a plurality). 
     Directional phrases used herein, such as, for example and without limitation, top, bottom, left, right, upper, lower, front, back, and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein. 
     In addressing deficiencies of known designs, embodiments of the present invention provide a mounting device that attaches securely and easily to a stroller, carriage, pram, walker, wheelchair or other pushchair. As employed herein, the term “stroller” shall be used to mean a stroller, carriage, pram, walker, wheelchair or other similar device. It is a further object of the invention to provide an umbrella suitable for attachment to the mounting device that works on strollers, wheelchairs and walkers, and protects users of virtually all heights from all directions of rain. In these respects, the umbrella mounting device for a stroller, according to the present invention, substantially departs from the conventional concepts and designs of the prior art, and in doing so, provides an apparatus primarily developed for purposes of protecting the user of the stroller from inclement weather. 
     Referring to the drawings,  FIG. 1  depicts an adjustable umbrella assembly according to a non-limiting embodiment of the present invention, generally designated with the reference numeral  10 , attached to a conventional folding or collapsible stroller  12 . The stroller  12  seats a young child (not shown) who may be protected from rain, wind and cold by a canopy  14  or other suitable rain shield (not shown), such as those commonly available from stroller manufacturers and retail stores carrying strollers and accessories. The umbrella assembly  10 , which may also attach to a pram, baby carriage, wheelchair, or other suitable device, includes an umbrella portion  15  having a cover  16  and a telescoping shaft  18 . Telescoping shaft  18  includes a lower section  20  and an upper section  22  slidable within lower section  20 . Lower section  20  of shaft  18  is coupled to an upper portion of the frame  23  of the stroller  12 , preferably at or about a handle portion  24  by a clamping mechanism  25  as shown in  FIGS. 1-3 . The clamping mechanism is described in further detail below. It is to be readily appreciated that such positioning of the umbrella assembly  10  protects a caregiver (or other person pushing the stroller) from precipitation or other environmental conditions (e.g., without limitation, sunlight). 
     As commonly utilized in known umbrella designs, cover  16  is generally formed from a lightweight waterproof or water resistant material, such as nylon, vinyl, canvas or other suitable material used in umbrella manufacture, which is sized and cut to provide a selected diameter for the particular umbrella. Such diameter should be selected to provide rain, wind and precipitation protection for an adult standing underneath. Aside from further details of the telescoping shaft provided below, the remainder of umbrella portion  15  may be fabricated using generally any suitable collapsible umbrella mechanism. 
     Having thus described an overview of an example embodiment of an umbrella portion  15  according to an embodiment of the invention, an example embodiment of a clamping mechanism  25  will now be described in conjunction with the FIGS., particularly in conjunction with the exploded view of  FIG. 4 . The example clamping mechanism  25  of  FIG. 4  serves two general functions: first it serves to couple umbrella portion  15  to stroller  12 , and second it serves to allow for the adjustment of the relative positing of umbrella portion  15  with respect to stroller  12 . 
     In providing the first function, clamping mechanism  25  includes a first clamp member  30  having a threaded shaft  32  extending through a portion thereof such that a first end  34  of threaded shaft  32  protrudes from a first side of clamp member  30 , and an opposite second end  36  protrudes from an opposite second side of clamp member  30 . A second clamp member  38  includes a pivot pin  40  that interlocks with a corresponding portion of first clamp member  30 , creating a hinge point that allows the two clamp members  30 ,  38  to cooperatively engage, and be tightened, on a selected portion of the stroller  12 , preferably at or near the handle portion  24 . The two clamp members  30 ,  38  are tightened by turning a stroller tightening knob  42  threadedly disposed on threaded shaft  32  at or near first end  34 . Stroller tightening knob  42  is preferably formed from an inner half  44  and an outer half  46  that are fused together. A threaded nut  48  is preferably installed in the tightening knob  42  during manufacture. Preferably, such elements are made from a composite material such as reinforced polycarbonate (or other type of composite) or other suitable material. In use, the tightening knob  42  opens and closes the clamp formed by the first and second clamp members  30 ,  38  to secure the umbrella assembly  10  to the stroller  12 . Preferably, the tightening knob  42  is manufactured to only loosen a selected amount, and thus cannot be removed from the threaded shaft and potentially lost by a user. 
     Preferably, one or both of clamp members  30 ,  38  are provided with a number of generally small grip protrusions  50  molded into the concave clamp area (not numbered) thereof. The grip protrusions  50  allow the clamp formed by the first and second clamp members  30 ,  38  to grip the cushioned (rubber, foam, plastic or metal) handles or other selected portion of a stroller. 
     In a preferred embodiment, the surface of the outer half  46  of tightening knob  42  contains an embossed star logo to differentiate the tightening knob from the positioning knob (discussed below) for the user. 
     In providing the second function, clamping mechanism  25  includes a positioning knob  60  formed from inner and outer halves  62  and  64 , respectively. Similar to tightening knob  42  previously discussed, such elements are preferably made from a composite material such as reinforced polycarbonate (or other type of composite) or other suitable material. A threaded nut  66  is preferably installed in the positioning knob  60  during manufacture. When the positioning knob  60  is tightened on threaded shaft  32  at or about second end  36 , the umbrella portion  15  is held in the chosen position. The user is able to adjust the angle of the umbrella portion  15  relative to the stroller  12  depending on the direction of the rain and/or for the placement of the mounting device on the particular stroller.  FIG. 1  shows an example of the umbrella portion  15  positioned generally parallel to the ground.  FIG. 2  shows an example of the umbrella portion  15  positioned at roughly a 45 degree angle with respect to the ground. It is to be appreciated that such particular positioning as shown in  FIGS. 1 and 2  is shown for example purposes only and is not meant to be limiting upon the scope of the present invention and that the umbrella portion  15  may be positioned at other angles other than those shown. As shown in  FIG. 3 , the user can also turn the umbrella 180 degrees from the position shown in  FIG. 1  so that the umbrella portion  15  can be stored on the stroller  12  in a downward position when not in use. Preferably, the positioning knob  60  is manufactured to only loosen a selected amount and thus cannot be removed from the threaded shaft and potentially lost by a user. 
     Continuing to refer to  FIG. 4 , lower section  20  of shaft  18  is preferably formed from first and second halves  70  and  72 , respectively. During manufacture, first half  70  and second half  72  are fused together with a shaft ring  74  to create a hollow cylindrical tube in which the upper section  22  of telescoping shaft  18  can then be inserted. Shaft ring  74 , which is fused to the upper end of the two halves  70 ,  72  reinforces the fusing of the two halves and provides a generally smooth transition for upper section  22  to slide therein. 
     Lower section  20  of telescoping shaft  18  includes a concentric ring portion  80  at the opposite end of the shaft ring  74 . The concentric ring portion  80  of second half  72  includes a number of depressed detents  82  arranged in a circular manner. The depressed detents  82  correspond to a number of raised buttons  84  disposed on first clamp member  30 . When assembled, each of the number of buttons  84  snap into a corresponding one of the number of detents  82 , thus allowing the angle of umbrella portion  15  to be adjusted by loosening, adjusting, and retightening of positioning knob  60 . 
     In the example embodiment shown in  FIG. 4 , each of the halves  70 ,  72  of lower section  20  are provided with a number of recessed apertures  90  spaced at generally equal intervals. In a preferred embodiment, such apertures are spaced generally one inch apart, with finger access to allow umbrella height adjustment for users. Upper section  22  of telescoping shaft  18  is fitted with a spring loaded button  92  that is inserted into the lower section  20  of telescoping shaft  18 . The button  92  locks into one of the multiple recessed apertures  90  as selected by a user according to user height and preference. 
     It should be appreciated that an umbrella that attaches to a stroller to provide protection for the user in inclement weather has been described, with reference to preferred embodiments illustrated in the accompanying drawings, but that other modifications may be made to this preferred embodiment. It will be appreciated that the present invention is not limited to those precise embodiments, and that various changes and modifications may be made thereto by one of ordinary skill in the art without departing from the scope or spirit of the invention, which is defined in the following claims. 
     In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word “comprising” or “including” does not exclude the presence of elements or steps other than those listed in a claim. In a device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The word “a” or “an” preceding an element does not exclude the presence of a plurality of such elements. In any device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The mere fact that certain elements are recited in mutually different dependent claims does not indicate that these elements cannot be used in combination.
