referring now to the drawings , particularly to fig1 and 2 , there is illustrated an umbrella / leash combination generally designated 10 with an umbrella canopy in closed and opened positions , respectively . the umbrella is mounted on a shaft 12 having a handle 14 at one end and a coupling 16 at its opposite end for connecting the umbrella with one end of a leash 18 . it will be appreciated that leash 18 may be releasably secured to a collar 20 on the pet , in this instance a pet dog is illustrated . in fig2 the umbrella / leash combination is illustrated with the umbrella canopy 22 in an opened position overlying the pet . while the canopy in the opened position may be circular ( as discussed hereafter ), preferably the canopy is in a generally oval configuration in plan with the major axis of the oval configured canopy extending in a vertical plane also containing the shaft 12 and handle 14 . from a review of fig1 and 2 it will be appreciated that the canopy 22 is supported by a plurality of ribs or spokes 24 which in turn are supported by a plurality of struts 25 . canopy 22 is also preferably formed of a clear plastic see - through material , preferably vinyl , although other materials including opaque materials can be used . referring now to fig3 and 4 , the shaft 12 mounts a sleeve 26 slidable axially along the shaft 12 between detented canopy opened and closed positions illustrated in fig3 and 4 , respectively . as illustrated in fig3 , the sleeve 26 is detented in the canopy opened position by a spring biased tab 28 carried by the shaft 12 . tab 28 is receivable in an opening or slot , not shown , through the sleeve 26 when the sleeve 26 is advanced to the canopy opened position . another spring biased tab 30 is carried on the shaft 12 at a location adjacent the handle 14 and , in cooperation with sleeve 26 , similarly serves to detent the sleeve 26 in the canopy closed position as illustrated in fig4 . the ribs 24 are pivotally mounted at proximal ends to sleeve 26 . the opposite distal ends of ribs 24 are secured to margins of the canopy 22 . any suitable connection between the distal ends of the ribs 24 and the canopy 22 may be utilized and is well known in the art . as illustrated in fig3 and 4 , the sleeve 26 has an annular recess 27 angled relative to shaft 12 . proximal ends of the ribs 22 are pivotally mounted to sleeve 26 in the annular recess 27 and slots are formed in the lower portion of the sleeve 26 to accommodate the pivoting movement of the ribs 22 when the umbrella is moved between canopy opened and canopy closed positions . while six ribs and six struts are illustrated in this preferred embodiment , it will be appreciated that a fewer or greater number of ribs and struts may be utilized to support the canopy . similarly , a hub 34 is mounted on shaft 12 at a location along the shaft 12 remote from the handle and on the opposite side of the sleeve 26 from the handle 14 . hub 34 is preferably fixed to the shaft but may be movable relative thereto . the hub 34 includes an annular recess 36 in which proximal ends of the struts 25 are pivotally mounted to the hub 34 . upper edge margins of the hub 34 have slots for receiving the struts 25 in the canopy closed position illustrated in fig4 . the opposite ends of struts 25 are of course pivotally connected to the ribs 22 intermediate opposite ends of the ribs . it will be appreciated that planes p 1 and p 2 passing through the annular recesses 27 and 36 of the movable sleeve 26 and hub 34 , respectively , lie in parallel planes . also it will be appreciated that the major axis of the oval shaped canopy lies in a vertical plane generally also including the shaft 12 and normal to planes ρ 1 and ρ 2 . thus the shaft 12 and the planes p 1 and p 2 passing through sleeve 26 and hub 34 in the recesses 27 and 36 form an included angle α in the vertical plane containing the major axis of the canopy 22 . the angle α preferably lies in a range of about 30 °- 60 °. it will also be appreciated that the minor axis of the oval shaped canopy extends perpendicular to the major axis and passes perpendicularly through the vertical plane containing the shaft 12 and the major axis of the oval shaped canopy . the handle 14 and coupling 16 for the leash lie on respective opposite sides of the minor axis . also , as illustrated in fig3 a , the handle 14 may comprise a straight handle 14 a as compared with the arcuate handle 14 illustrated in fig3 . additionally , the sleeve 26 may have a non - circular interior opening complementary to the shaft , or maybe be slidably detented to the shaft to prevent the canopy from twisting relative to the shaft . from a review of the drawing figures , it will be appreciated that the ribs 24 defining the generally oval shaped canopy are symmetrical about the major axis . ribs 24 along opposite sides of the canopy are , however , different in length as compared to the ribs 24 extending along the major axis of the oval shaped canopy . likewise , the struts 25 are symmetrical about the major axis . struts 25 along the opposite sides of the canopy are , however , different in length as compared with the struts parallel to the major axis . further , as illustrated in fig3 , the strut 25 a between hub 34 and the rib 24 forwardly of the minor axis is shorter than the strut 25 b extending between hub 34 and the rearwardly extending rib 24 on the opposite side of the minor axis . thus , the struts paralleling the major axis of the oval shaped canopy 22 and on opposite sides of the minor axis are unequal in length relative to one another . in use , the leash 18 is attached to the pet collar 20 and also to the distal end of the umbrella i . e ., to the coupling 16 . any suitable connection may be used . in the canopy closed position , the shaft 12 serves as part of the leash for the pet . to open the umbrella during inclement weather conditions , detent 30 is depressed enabling the sleeve 26 to be manually displaced along shaft 12 in a direction away from the handle 14 and toward the coupling 16 . upon the sleeve 26 obtaining a position along the shaft in registration with tab 28 , the tab is biased outwardly into the slot formed on the sleeve 26 to maintain the sleeve in position along the shaft with the canopy extended in the canopy opened position as illustrated in fig3 . it will be appreciated that the different lengths of the ribs 24 and the struts 26 enable the canopy 22 to open into a generally oval configuration in plan . additionally , it will be appreciated that in the canopy opened position , a vertical plane passing through the major axis also contains the shaft 12 . the included angle between the shaft 12 and the planes p 1 and p 2 preferably lies in a range of approximately 35 °- 60 °. thus the canopy extends forwardly from the individual holding the handle 14 , lies in a generally horizontal position and extends lengthwise from the individual . when it is desired to close the canopy 22 , the tab 28 is depressed releasing the sleeve 26 for manual sliding movement in a direction toward the handle where it is once again detented by the tab 30 in the canopy closed position . referring now to fig6 , there is illustrated a further embodiment of the combined umbrella / leash hereof with a canopy having a generally circular configuration . in this form , the shaft 12 a connects to the movable sleeve 26 a at the apex of the circular canopy 22 a . the shaft 12 a extends below the canopy to a fixed hub similarly as in the previous embodiment to which the struts are pivotally connected . in this form , the ribs 24 a supporting the canopy 22 a are of equal length while the struts supporting the canopy are of unequal length . this enables the circular canopy to lie in a generally horizontal orientation when in the canopy opened position with the shaft 12 a being inclined relative to the canopy . while the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment , it is to be understood that the invention is not to be limited to the disclosed embodiment , but on the contrary , is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims .
a pet umbrella combines an umbrella and a leash . the umbrella includes a shaft carrying a canopy moveable between open and closed positions . in the open position , the convex side of the canopy faces the umbrella handle . a leash is secured to the opposite end of the shaft on the concave side of the canopy . the canopy is preferably oval in plan and formed of clear plastic see - through material . the major axis of the oval defined by the canopy forms a plane with the shaft whereby the shaft forms an included angle in the plane with the shaft of less than 90 ° and preferably about 30 °- 60 °.
