fig2 illustrates front view of a protective cover 102 . in an embodiment , the protective cover 102 can be an umbrella or an umbrella like device . in another embodiment , the protective cover 102 includes a canopy portion 202 and a shaft portion 204 . the canopy portion 202 of the protective cover 102 can further include an upper portion 206 and a lower portion 208 . in an embodiment , the upper portion 206 of the canopy 202 can be made of an suv and a permeable textile material and the lower portion 208 of the canopy 202 can be made of a clear permeable textile . the upper portion 206 , through an suv and permeable textile based material , provides a durable and rigid support to the protective cover 102 and is made of suitable , weather - proof material to bear conditions like harsh rain drops , frozen precipitation etc . the lower portion 208 of the canopy 202 , on the other hand , is made of a transparent material to allow the operator or caregiver of the stroller 104 clear visibility . in an embodiment , the upper portion 206 and the lower portion 208 can be placed over each other so as to create a vented hood design for the canopy 202 . such design ensures a secure exit of incoming wind , thereby preventing the protective cover 102 from inverting against the force of wind . the shaft portion 204 of the protective cover 102 , in an embodiment , comprises a central shaft 210 , a telescoping means 212 , a flexible metal tubing 214 , an attachment device 216 and a flared end piece 218 . in an embodiment , the central shaft 210 can comprise of two or more central shaft components , with one shaft component being slidably movable within the recess of the other component . the different shaft components of the central shaft 210 can be joined at the telescoping means 212 . referring to fig2 , shaft component 210 b of central shaft 210 is slidable against the recess of slide components 210 a as is explained in detail in fig6 . the central shaft 210 is preferably made of aluminum and metal so as to provide a lightweight yet stiff protective cover which is durable and weather - proof . in another embodiment , the telescoping means 212 can be provided at a point where two shaft components of the central shaft 210 meet . the telescoping means 212 is a rotating sleeve that allows for adjustment of umbrella height . twisting the telescoping means 212 in an anti - clockwise manner loosens the connection between the two shaft components allowing for the two shaft components to slide freely . an operator can then adjust the length of the central shaft 210 as per his / her convenience . once the desired length is achieved , the telescoping means 212 can be twisted in a clock - wise manner to hold the shaft components of the central shaft 210 in their current position . the length adjusting feature is particularly useful for users of different heights who want the protective cover to be matching to their heights . this feature can also be useful under circumstances where one needs to adjust the height of the protective cover 102 depending upon the intensity of wind or rain . in another embodiment , the flexible metal tubing 214 can be provided at a shaft component of the central shaft 210 to allow for small adjustments in the direction of the protective cover 102 . functionally , moving the protective cover 102 bends the flexible metal tubing 214 . the metal tubing 214 retains its shape until it is bent into another position . thus , the flexible metal tubing 214 provides an axis of maneuvering the direction of the protective cover 102 . in yet another embodiment , the attachment device 216 provided on the shaft portion 204 further comprises of an inner clamp 220 and an outer clamp 222 . the attachment device 216 is a means to attach the protective cover 102 to the body of the carriage 104 , also referred to as stroller and / or baby carriage . a dual clamp mechanism , as is described below with reference to subsequent figures , can be configured to the attachment device 216 to provide separate clamps to attach , respectively , to the central shaft 210 of the protective cover 102 and the carriage body 104 . the positioning of the two clamps in close vicinity and on the same device ensures that this arrangement is clutter free and occupies a minimum possible space . the dual clamp mechanism also provides an additional benefit of swirling a closed protective cover 102 around the inner clamp axis for easy storage . the attachment device 216 can be designed to be comfortably attached to any type of carriage . in yet another embodiment , the flare end 218 towards the end of the central shaft 210 is designed so as to provide a smooth edge to an operator using the protective cover 102 . the flare end 218 can , preferably , be of a tapering nature and be made of smooth polymeric material . fig3 illustrates side view 300 of the attachment device 216 according to an embodiment . the inner clamp 220 , also referred to as upper clamp 220 hereinafter , can be configured to attach to the shaft portion 204 of the protective cover 102 and provide a firm grip to the protective cover 102 while the outer clamp 222 , also referred to as the lower clamp 222 hereinafter , can be configured to attach to the carriage body 104 , thereby providing a firm grip to the carriage 104 . this gives the operator of the carriage 104 an advantage to not engage his hands to hold the protective cover 102 and instead use his hands to maneuver the carriage 104 . the clamps , 220 and 222 , can be rotated around their own axis and their clockwise or anticlockwise twisting can tighten or loosen their respective attachment to central shaft 210 of the carriage body 104 . the tightening and loosening of the inner clamp 220 can be particularly helpful in setting a preferred orientation for the protective cover 102 . in yet another embodiment , the attachment mechanism can also be used with other carriage 104 and / or strollers . fig4 illustrates different orientations 400 of a protective cover 102 achieved through a clamp mechanism according to an embodiment . orientations 400 can include different orientations 402 , 404 , and 406 of the central shaft 210 , and hence of the protective cover 102 , achieved due to differential rotation of the central shaft 210 brought about by loosening the inner clamp 220 . once the desired orientation is set , the inner clamp 220 can be tightened in its position . the outer clamp 222 can remain attached to the carriage body 104 during the whole exercise . in a preferred embodiment , the clamps are made of heavy duty plastic and aluminum . orientation 402 demonstrates an open position of the protective cover 102 and the orientation 406 demonstrates the closed position of the protective cover 102 . fig5 illustrates a side view 500 of a baby carriage 104 with a protective cover 102 in closed position according to an embodiment . referring to fig5 , the inner clamp 220 enables an operator to place the closed protective cover 102 at a location adjacent to the main body of the carriage 104 . the closed protective cover 102 , when not in use , can be rotated around the inner clamp 220 and placed sideways to a handle or bar of the carriage 104 . the inner clamp 220 enables a 360 ° rotation of the closed protective cover 102 . further , the handle or bar can be configured to provide a strap 502 to keep the closed protective cover 102 at its position . this offers a simplistic and clutter free arrangement to store the protective cover 102 when not in use . also , when desired to use , the mechanism offered , as disclosed in the embodiment described above , to open the protective cover is simple and easy - to - follow . the operator , in such cases , can free the strap 502 and rotate the protective cover 102 along the inner clamp 220 axis to an upright position and open the protective cover 102 . the direction and height of the protective cover 102 can then be adjusted according to the embodiments described above . the clamping mechanism of the present invention , thus , provides an advantage not only in terms of space and convenience of use to an operator , but , functionally , by allowing an operator to adjust the height and bend of the protective shield as well as providing a complete flexibility of rotating the protective cover by 360 degree , also offer novel solution to the operator . fig6 illustrates a mechanism 600 to adjust the length of the central shaft 210 using the telescopic means 212 according to an embodiment . at 602 , the central shaft 210 is provided with distinct shaft components 210 a and 210 b joined at the telescopic means 212 . the telescopic means 212 , as mentioned above , is a sleeve which can be twisted to effect a loosening or tightening the connection between the two shaft components allowing them to slide freely against each other . at 602 , the telescopic means 212 is loosened to ease the connection between the shaft components 210 a and 210 b so as to enable the shaft component 210 b to be slidable against the recess of shaft component 210 a . at 604 , the length of the central shaft 210 is adjusted by allowing just the right length of the shaft component 210 b to slide against the recess of shaft component 210 a . at 606 , once the desired length is achieved , the telescoping means 212 is tightened to hold the shaft components of the central shaft 210 in their current position .
