a first embodiment of the present invention shall be discussed with reference to fig1 , which illustrates a top - down view of an umbrella and its umbrella canopy 10 . the umbrella canopy 10 includes ribs 12 a and 12 b for sustaining the structure of the umbrella canopy 10 when it is fully opened , a canopy covering including canopy panels 14 disposed between the ribs , and a vertically - deployable sun shade 16 . in the present embodiment , the sun shade 16 resides underneath the panel 14 . it should be understood that more than one vertically - deployable sun shade 16 may reside underneath any or all of the additional panels of the umbrella canopy 10 . as shown in fig2 , the sun shade 16 includes a sun shade member 16 a , which can be made of various materials as described above . as one example , the sun shade member 16 a can be made of a transparent or semi - transparent material embedded with or otherwise made of an anti - ultraviolet light chemical . alternatively , the sun shade member 16 a can be made of cloth conventionally used in window coverings . one end of the sun shade member 16 a is affixed in a conventional manner to a deployment portion 16 b ( shown in phantom .) in the illustrated example , the deployment portion 16 b is a conventional spring - loaded window shade roller , and the sun shade member 16 a is wrapped around the deployment portion 16 b in a conventional manner . it should be understood that the roller shown is of a type used in conventional window coverings or the like . it should also be understood that the deployment portion 16 b and the sun shade member 16 a could also be of a type conventionally used with a set of venetian blinds , mini - shades , honeycomb blinds , pleated shades or of another type entirely . when using such a sun shade member 16 a , the sun shade 16 includes an appropriate blind support which functions as the sun shade deployment portion 16 b . an activation portion 16 c , shown in fig2 as a ring , provides a user with the ability to activate or deploy shade member 16 a from the deployment portion 16 b . the activation portion 16 c can vary depending on the nature of the deployment portion 16 b , and may be an integral part of the sun shade member 16 a . specifically , the activation portion 16 c may simply be an edge of the sun shade member 16 a , as illustrated in fig5 . further , it should be understood that the activation portion 16 c can be comprised of a mechanized system for raising and lowering the sun shade member 16 a by touch or remote control . fig1 illustrates the vertically - deployable sun shade 16 as generally parallel to the umbrella canopy periphery 18 upon opening the umbrella by an umbrella activation member ( not shown ), such as a crank . in one embodiment , the vertically - deployable sun shade 16 is permanently affixed to the rib 12 b by an attachment portion 16 d . in a preferred embodiment , the attachment portion 16 d allows the sun shade 16 to pivot and align itself generally parallel or adjacent to the rib 12 b . immediately prior to closing the umbrella canopy 10 by use of the umbrella activation member , it is required that a user move the sun shade 16 toward the rib 12 b such that the sun shade 16 lies generally parallel to the rib 12 b . a receiving member 22 connected to the rib receives a protrusion 16 e extending from the sun shade 16 such that the protrusion 16 e snaps into the receiving member and is thus firmly held in place . further , an additional receiving member 24 ( shown in phantom ) is preferably attached to the umbrella canopy periphery 18 and / or the rib 12 a for securing the sun shade 16 when it is generally parallel to the umbrella canopy periphery 18 . alternatively , the protrusion 16 e and the additional receiving member 24 can be removed and the attachment portion 16 d can provide adequate strength to hold the sun shade 16 in a position generally parallel to the umbrella canopy periphery 18 . additionally , it should be noted that the umbrella canopy 10 includes an umbrella hub 11 , as is typical of an umbrella . fig3 a through 3e illustrate an alternative embodiment which includes a structure for automatically rotating a vertically - deployable sun shade that is an integral part of an umbrella . for ease of illustration , fig3 a through 3e show the umbrella canopy of the umbrella with the umbrella covering removed . unlike fig1 , fig3 a through 3e illustrate sun shade 16 as a pleated blind . referring to fig3 a , the sun shade 16 attaches to the umbrella at each end by the attachment portions 16 d , each comprised of a retaining bracket in the illustrated example . fig3 a illustrates a raised position for the sun shade member 16 a and fig3 b shows a lowered position for the sun shade member 16 b . additionally , one of the attachment portions 16 d at a first end of the sun shade 16 is set or moveably attached to a runner 13 that is affixed to the rib 12 b . the runner 13 allows the first end of the vertically - deployable sun shade 16 to slide freely in a trajectory generally parallel to the rib 12 b , and additionally , the attachment portion 16 d at the second end of the sun shade 16 allows the second end of the sun shade 16 to rotate freely , such that as the umbrella is closed the sun shade 16 is rotated into a position substantially parallel to the ribs . the runner 13 and attachment portion 16 d are more closely illustrated in fig3 c . the progressive closing of the umbrella canopy is shown in fig3 d and 3e . referring to fig3 c , the runner 13 includes a channel or groove by which the attachment portion 16 d can be inserted into and allowed to move in a trajectory generally parallel to the rib 12 b . it should be additionally noted that the runner 13 can be an integral part of the rib 12 b . with the vertically - deployable sun shade 16 disposed in this manner , the vertically - deployable sun shade 16 is able to collapse in tandem with the ribs of the umbrella canopy 10 as the umbrella canopy 10 is closed by the umbrella activation member ( not shown .) a wire ( not shown ) embedded in or that runs generally parallel to the rib 12 b provides the work necessary for this novel operability . one end of the wire is connected to the appropriate attachment portion 16 d . the other end of the wire is attached to a cable ( not shown ) running from the umbrella activation member to the umbrella hub 11 . this cable is disposed such that an activation of the umbrella activation member to close the umbrella canopy 10 increases tension in the cable , and an activation of the umbrella activation member to open the umbrella canopy 10 releases tension in the cable . such a disposition causes the movement of one end of the vertically - deployable sun shade 16 along the runner 13 as the umbrella canopy is closed . as this occurs , each end of the vertically - deployable sun shade 16 rotates as necessary . fig3 d and 3e illustrate this movement . conversely , upon opening the umbrella canopy 10 by utilization of the umbrella activation member , the force of gravity provides for the opposite movement to occur due to a release of tension in the cable . hence , in this embodiment , there is no need for a user to manually rotate the sun shade 16 upon opening or closing the umbrella canopy 10 . in another embodiment of the invention , a vertically - deployable sun shade is provided which can attach to an umbrella or another object . referring again to fig2 , the attachment portions 16 d comprise clips that allow the sun shade 16 to be clipped on to the umbrella canopy periphery 18 . it should be understood that the clips resembling the operation and feel of a clothespin or similar device . it should be further understood that the clip can be made of many different materials , among them plastic and metal . of course , other devices can be used for the attachment portion 16 d that permit the sun shade 16 to be easily attached and detached from the umbrella canopy . fig4 illustrates the vertically - deployable sun shade 16 with clip type attachment portions 16 d . another embodiment of the present invention wherein the vertically - deployable sun shade is an integral part of the umbrella canopy is discussed with reference to fig5 . fig5 shows a front view of an umbrella wherein the vertically - deployable sun shade 16 is attached to the panel 14 at the attachment portion 16 d utilizing conventional materials and methods . in the illustrated embodiment , an activation portion 16 b is comprised of a tie , or long piece of material , including a snap fastener 28 a . a complementary portion 28 b to the snap fastener is conventionally affixed to the panel 14 . it should be readily understood that the activation portion 16 b could instead include velcro , a clip , or some other means for fastening the activation portion 16 b to the umbrella canopy 10 in order to contain the sun shade member 16 a . it should be noted that in this embodiment the activation portion 16 b also constitutes a containment portion for containing the vertically - deployable sun shade 16 in order to compactly store the vertically - deployable sun shade 16 . it should be further noted that in this particular illustrated case the deployment portion 16 b and the sun shade member 16 a are the same thing , since an edge of the sun shade member 16 a serves as the activation portion 16 c . yet another embodiment of the present invention is illustrated in fig6 . the present embodiment provides for an enclosure , wherein the enclosure is formed by a plurality of the previously described vertically - deployable sun shades 16 either integrated into an umbrella or as a temporary part thereof . fig6 illustrates the case where the sun shades 16 are not an integral part of the umbrella . in this embodiment , the aforementioned enclosure is formed from the attachment of each of the plurality of sun shades 16 to one another . because a gap may occur between the vertically - deployable sun shades 16 , an attachment strip 30 made of the same material as the sun shade member 16 a can be utilized in order to fill such gaps . the attachment strip 30 should be made of the same material as the sun shade member 16 a , although it can be made of a different material entirely . it should be understood that although the figure illustrates the use of temporary sun shades 16 , the sun shades 16 could also be integrated into the umbrella canopy 10 as previously described . each of the attachment strips 30 may be comprised of a snap fastener , a clip , velcro , or other attachment devices . in the illustrated example , the attachment strips 30 comprise velcro and the sun shades 16 include the complementary velcro components necessary for such attachment ( not shown .) it should also be noted that , preferably , the sun shade member 16 a is made of mosquito netting or a transparent or semi - transparent material . further , stakes 31 can be added to stake the sun shade portions to the ground . another embodiment of the invention in which each sun shade folds up within the umbrella canopy in an inverted “ v ” shape is shown in fig7 . in this embodiment , the sun shade includes two sun shade portions 40 ( indicated in phantom to allow underlying structure to be shown and each being the same in structure as the above described sun shade ) are each mounted to a hinged member 42 , which in turn is mounted to the umbrella ribs 44 via rod end couplings 46 that are attached to attachment points 48 . the hinged member 42 acts as a deployment structure to deploy the sun shade portions 40 into a position in which the shades of the sun shade portions 40 can be vertically deployed . fig8 illustrates the hinged member 42 in its full extended position when the umbrella canopy is up . fig9 illustrates the hinged member 42 when the umbrella canopy is down . as shown in fig8 , the hinged member 42 preferably includes a central hinge 50 including an integral tension spring 52 that helps the rod to fold into an inverted “ v ” shape shown in fig9 when the umbrella canopy is lowered down . the sun shade portions 40 are preferably mounted to provide overlap therebetween . for example , one sun shade portion 40 is preferably mounted to a front portion of one arm 54 of the hinged member 42 , while a second sun shade portion 40 is mounted to a back portion of a second arm 56 of the hinged member 42 . accordingly , the sun shade portions 40 do not interfere with one another when the hinged member 42 is moved to the inverted “ v ” position , and are moved into positions that are generally parallel with a rib of the umbrella canopy when the umbrella canopy is closed . other mounting positions are possible , for example , the sun shade portions 40 can be mounted below the first arm 54 and second arm 56 . still further , the sun shade portions 40 can be mounted such that they do not overlap , but this would be less desirable than an overlapping installation . in the above embodiments , it should be understood that additional weight provided in the vertically - deployable sun shade might be useful in windy weather conditions . therefore , the vertically - deployable sun shade of the above embodiments can additionally include a metal or otherwise appropriately heavy object in order to provide enhanced stability in windy weather conditions . in conventional umbrellas , the canopy is deployed by rotating a crank mechanism that operates to wind a line around a spindle . the line is attached to hub that moves up and down the umbrella pole . the hub is connected to the canopy deployment structure . with the crank is turned , the line pulls the hub upward to open the canopy . when lowering the umbrella , however , such conventional crank mechanisms are not designed to apply a positive force to the line to pull the canopy closed and the force of gravity is primarily relied upon to close the canopy . in the above described embodiments in which the sun shades are pulled generally vertical upon closing the umbrella , however , it would be desirable to provide a positive force when closing the umbrella canopy to help in overcoming the additional frictional forces created by pulling the sun shades to the vertical position . fig1 illustrates a bi - direction pulley system that is preferably used to open and close an umbrella canopy . a first cable 60 is attached to a spindle 62 within the body of the umbrella pole , traverses through one or more upper pulleys 64 , exits the pole at a location above the umbrella hub ( now shown ), and has an end 66 attached to the top the hub . when a crank attached to the spindle 62 is turned , the first cable 60 winds around the spindle 62 and pulls the hub up forcing the umbrella ribs and attached canopy to open . a second cable 68 is also attached to the spindle 64 on a side opposite to the first cable 60 , and is preferably separated from the first cable 60 a divider 70 provided on the spindle 62 . the second cable 68 , traverses through one or more lower pulleys 72 , exits the pole at a location below the umbrella hub and is attached to the bottom of the hub . when the crank is turned in the opposite direction , the second cable 68 is wound around the spindle 62 and applies a positive closing force to the hub through the lower pulleys 72 . in other words , the two pulley systems are oppositely wound so that one applies a positive opening force and the other applies a positive closing force the invention has been described with reference to certain preferred embodiments thereof . it will be understood , however , that modifications and variations are possible within the scope of the appended claims . for example , while the invention has been described with reference to an umbrella , the invention is also applicable to other types of shades including awning canopy or a tent canopy , as just one example . further , the invention is not limited to the specific mechanical structures illustrated in the preferred embodiments for folding the sun shades within in the canopy , but instead , is intended to cover any mechanical structure that accomplishes rotating the vertically - deployable sun shade or sun shade portions into a position generally parallel with a rib of the umbrella canopy when the umbrella canopy is closed . fig1 , for example , illustrates a further embodiment in which an actuating mechanism 80 is provided to pull sun shade portions 82 substantially vertical as shown in fig1 .
the invention adds one or more vertically - deployable sun shades to an umbrella for selectively providing shade for one or more users of an umbrella . more specifically , the sun shade resembles a conventional shade or set of blinds for covering a window . the size , shape , materials , and arrangement of the sun shade can vary according to user preferences or the intended manner or place of use .
