turning now to the drawings , particularly fig1 to 3 , the convertible bag of the present invention is generally designated by the numeral 10 and includes two principal components , a carry bag 12 and a staff bag component 14 . the carry bag component 12 is best shown in fig3 and is generally of conventional construction having an elongate tubular body 16 with a base 18 at the lower end and a collar 20 at the upper end . the body 16 may be of any suitable material such as cloth or synthetic fabric . the base 18 is generally formed of a rigid plastic material having a bottom plate 22 and a cylindrically extending lip or flange 24 . the upper collar 20 is similarly conventional and may be fabricated from a rigid plastic material and may include one or more transversely extending dividers for maintaining the golf clubs in a separated position . a pocket 28 is affixed to the exterior of the body 16 having zipper 30 to provide access to the interior of the pocket . a smaller sub - pocket , not shown , is accessed by fastener or zipper 30 . a carry strap 34 is secured at its upper end to a ring 36 secured to the collar 20 . the opposite end of the carry strap 34 is secured to the bag at a location above pocket 28 at a ring 38 . typically the ends of the strap 34 are provided with snap hooks so that the carry strap may be detached from the bag at rings 36 and 38 . a carrying handle 40 is secured to the front side of the carry bag . the handle is a molded plastic component having a lower end 42 secured to the body of the bag . the upper end of the carrying handle 44 is secured to the bag at a location below the collar and is formed having a groove or undercut portion 48 upwardly disposed as shown in fig3 . the groove serves to receive or seat the attachment strap as will be more fully explained hereafter . thus , the carry bag 12 is generally of conventional construction and may serve as a light weight , compact bag for the storage of golf clubs within the body 16 and accessory items such as balls and other equipment in the pocket 28 . carry bag 12 has utility as a stand - alone bag for this purpose . the carry bag may include a conventional stand or tripod 45 which , when retracted , would nest against the staff component of the bag system . however , if the golfer desires to add the benefit of a larger staff - type bag , the staff component 14 may be secured to the carry bag as shown in fig1 . the staff component 14 has a base 50 with a bottom plate 52 and a peripherally extending wall or flange 54 . the base defines an internal receptacle 56 configured to snugly receive the exterior of the base of the carry bag . preferably a rib or projection is provided in receptacle 56 to prevent relative rotation of the two bag components when assembled . a generally u - shaped sleeve 60 extends vertically from the base 50 . the sleeve has opposite vertical edges 62 and 64 which are oppositely positioned and configured so as to snugly engage the opposite sides of the body 16 of the carry bag . the upper end of the sleeve terminates at a location immediately below the collar 20 of the carry bag when the carry bag is seated in the staff bag component . as best seen in fig2 and 4 , a large vertical compartment 70 is secured to the sleeve extending substantially the length of the sleeve and the length of the carry bag . the compartment 70 has opposite sides 72 , 74 and rear surface 75 . surface 75 carries an elongated closure 76 , shown as a zipper , extending from the top of the compartment to the bottom . the compartment may be fabricated from any suitable material such as a fabric or synthetic material . appropriate insignia 80 may be placed on one or both of the surfaces 72 or 74 such as the name of the bag manufacturer , here indicated by the trademark &# 34 ; profound &# 34 ;. personalization of the insignia by use of an insert will be explained hereafter with reference to fig9 to 11 . in order to provide additional storage capacity , one or more additional pockets 90 are associated with the staff bag components . the pocket 90 is positioned at the bottom end of the staff bag component opposite the sleeve 50 . the pocket is shown as being secured to the base by one or more l - shaped arms 92 . as seen in fig1 when the carry bag and staff bag components are assembled , the pocket 90 assumes a position tightly engaging the front of pocket 28 of the carry bag to provide additional storage capacity and to provide the multiple pocket appearance of a staff bag . the attachment of the carry bag to the staff bag is accomplished by first seating the base of the carry bag in the base of the staff bag with the handle 40 and the carry strap 34 disposed outwardly as shown in fig1 and 3 . assembly is completed by securement of attachment means which are shown in fig1 and 2 as a strap 100 secured to the sleeve 60 at its upper end . in addition , a quick - release buckle 102 is secured to the opposite side of the sleeve near its upper end . the strap and buckle may be engaged by appropriate pivotal movement of lever 104 of the buckle . thus , to secure the carry bag in place , strap 100 is extended about the body of the carry bag near its upper end with a portion of the edge of the strap engaging or being seated in groove 48 . the free end of the strap is then passed through the buckle and lever 104 closed to tightly lock the bags together . this method of attachment is simple , convenient and does not require multiple fastening operations and is basically a lateral insertion operation termed &# 34 ; side entry &# 34 ;. conversion between carry bag and staff bag does not require transfer of golf club or golf equipment . all of the golfer &# 39 ; s basic golf equipment can be maintained in the carry bag portion of the convertible golf bag . the same carry strap and handle that are an integral part of the carry bag are also used as part of the assembled staff bag . the carry bag and the staff bag can be designed using materials and colors and designs to achieve a wide variety of cosmetic effects . further , contrary to prior art convertible bags , a portion of the body of the carry bag , including the pockets , handle and strap , form a portion of the body of the combination bag . the side entry insertion of the carry bag into the staff component has many advantages . lifting the carry bag to a vertical position above the staff component is not required as it is with concentrically positioned combination bags . with the side entry feature , the carry bag can easily be removed from the staff bag when the bags are on a golf cart , in a locker or a car trunk , avoiding excessive lifting . the large vertically extending compartment 14 of the staff component may be used for storage of various equipment and accessory items . if desired , compartment 14 may be used to store an integrally - mounted , collapsible pull cart . in the stored position , the pull cart and its components are fully contained within the large compartment . referring to fig4 through 8 , the pull cart is generally designated by the numeral 125 and has a frame assembly consisting of a vertical bar or rod 126 and a pair of spaced - apart arcuate members 127 and 128 which are secured to the arm and are also secured to the rigid sleeve 60 by a plurality of fasteners 130 such as wing nuts or other easy release fasteners . the entire cart assembly may be detached from the sleeve by removing fasteners 130 . as indicated above , the foldable pull cart 125 is an optional accessory item which can be included as part of the staff bag component if desired by the user . a handle 135 is pivotally secured near the top of the frame member 126 at pivot and locking assembly 131 . in the use position , the arm is extended and locked as shown in fig8 . the end of the arm 135 terminates at a padded grip handle 136 . a pair of spaced - apart stub shafts 140 and 142 extend from the upper surface of the arm and in the stored position extend rearwardly as seen in fig6 and 7 . &# 34 ; rearwardly &# 34 ; as used herein refers to toward the rear surface 75 of the staff bag . in the position shown in fig8 a holder 148 for a score card may be attached to the shaft 140 , 142 . axle support arms 150 and 152 are pivotally secured at their upper end to the frame member 126 . the axle support arms 150 and 152 each terminate at a short stub axle 154 . in the use position , the arms 152 and 154 are swung rearwardly to move them outwardly through opening 76 from their stored position . struts 160 and 162 extend from the frame member 126 to arms 150 and 152 , respectively , and serve to lock the axle support arms in the use position . in the stored position as shown in fig5 the handle , struts and axle arms are foldably disposed toward the rear of the storage compartment . the wheels 165 and 166 are each provided with conventional quick - release mechanism 168 . in the stored position , the wheels are secured to stub shafts 140 , 142 maintained in the position shown in fig5 . when the cart is to be placed into use , the wheels are removed from the stub shafts 140 , 142 and the cart unfolded as described above . once unfolded , the wheels 165 , 166 are attached to the axles at the lower end of the axle arms 150 , 152 by their respective quick - release mechanisms 168 . when the pull cart is in the use position as shown in fig8 the bag can be conveniently manually transported by the golfer . closure 76 may be partially closed . however , it will be appreciated that a portion of the closure must remain open to accommodate the protrusion of the cart . as seen in fig6 a tab or strap 170 may be provided to maintain the lower portion of the material of compartment 75 from engaging the ground when the pull cart is being used . the tab is connected to the frame to elevate the lower end of the compartment above the ground . as mentioned above , the staff bag and pull cart may be detached from the carry bag when the golfer wishes to use only the carry bag . further , if the golfer wishes to having the added capacity of the storage compartment for storage of golf equipment , accessories and clothing , the golf cart , which is an optional item , may be detached at fasteners 130 . garment sleeves 180 and 182 are provided in compartment 14 for storage of items such as rain wear and sweaters . the present invention also facilitates personalization of golf bags . many times , golfers prefer to have a particular insignia on the golf bag , such as the golfer &# 39 ; s name , a particular golf manufacturer &# 39 ; s logo , or identification of the golfer &# 39 ; s school or organization . personalization of bags has been difficult because this usually requires special order as embroidery or application of graphics to the bag normally must be done by the manufacturer prior to assembly of the bag . with the present bag , as shown in fig9 to 11 , a surface of one of the bag components can be conveniently personalized by the insertion of insert 200 . in fig9 and 10 , the staff bag component of the bag 14 is shown which on surfaces 70 and 72 is provided with a peripherally extending cover flap 202 which is shown as being generally trapezoidal in shape but which can be any suitable shape such as oval , square , etc . the flap 202 is fabricated of suitable fabric material and has an outer edge 204 which is secured to the bag by any suitable method such as stitching , adhesive bonding or dielectric bonding . the inner edge 205 is free so that a continuous flap is established . the underside of the flap 202 is provided with fastener components 210 at spaced - apart intervals . the fastener components are preferably one portion of a loop and pile fastener such as the type sold under the trademark velcro . the insert 200 has a configuration generally conforming to the configuration of the cover 202 . the outer surface of the insert 200 is provided with fastener components 212 which will matingly engage the portions 210 on the cover . suitable indicia 220 are printed , sewn , painted , embroidered or otherwise applied to the panel . as shown in fig1 , the indicia consists of the name of the golfer . in fig9 the indicia shown consists of the identification of a golf equipment manufacturer which would normally be applied to the bag when it is manufactured . if the golfer does not desire personalization of the bag , the golf equipment manufacturer &# 39 ; s insignia 80 remains visible . however , if the golfer wishes to personalize the bag , the golfer would remove the manufacturer &# 39 ; s insert 200a ( fig1 ) and apply the insert 200 as shown in fig1 by inserting it beneath the free edges of the flap 202 and securing the fastener components 210 and 212 . the advantage is that personalization does not have to be accomplished by special order of the entire bag . rather the golfer , when purchasing the bag , would simply order an insert with the selected indicia which insert would be custom made and would be sent to the golfer by the manufacturer . the golfer can then easily insert the personalized insert in the manner shown in fig1 . in many instances , golfers will either by choice or due to the vagaries of weather , find themselves playing in a shower or rain storm . in such a situation , most player &# 39 ; s first concern is to protect the golf clubs to keep them dry . rain covers or hoods of various types are provided for this purpose . as an alternative , many golfers carry towels with them which they will simply throw over the top of the golf bag . the present invention , as an accessory , provides a unique golf bag rain cover which has its own bag . as seen in fig1 , the rain cover 250 has an exterior pouch 252 defining an interior pocket having transversely extending opening 254 . a flap 256 extends across the opening 254 . the flap has one component of a loop and hook fastener 258 thereon and the pouch has a mating fastener section 259 thereon below the opening 254 . when the rain cover is to be deployed , the fastener sections 258 and 259 are separated and the flap 256 lifted . an elongate sleeve 260 may then be extended from the opening 254 . the sleeve 260 is secured to the inner side of the rear of the pouch . sleeve 260 is fabricated from any suitable material such as synthetic waterproof fabric or a plastic film . the rain shield is then reversed to the use position as shown in fig1 so the pouch 252 now occupies a position within the sleeve . in this position , elongate flap 275 extends over the opening 262 being stitched along its upper edge to the sleeve . the flap is shown as being generally trapezoidal having a fastener member 276 at its lower end which cooperatively mates with fastener member 278 at the lower end of the opening or slit 262 . the rain shield is secured at the upper end of the carry bag as shown in fig1 and 17 . preferably the carry bag has a mounting rod 280 which may be a solid rod or , as shown , is a telescopic rod 282 secured by brackets 284 . the upper end of rod 280 carries attachment section 285 which when inserted through the open lower end of the sleeve will attach to one of the fastener sections 258 , 259 on the pouch . thus , the rod can be extended to the desired height above the clubs in the bag and the sleeve attached to the upper end of the rod so that it will drape down over the upper edge of the bag to protect the golf clubs and to keep moisture from entering into the interior of the golf bag . the sleeve is maintained out of contact with the clubs for easier club removal and insertion . when it is desired to remove a club , flap 275 may be detached and lifted upwardly and a club removed through longitudinally extending slot 262 . fig1 to 20 show another system for attaching the staff and carry bag components 14 and 12 . the upper end of the sleeve 60 of the staff bag is provided with a lip 300 which defines a downwardly opening hook 302 . the carry bag has a flange 306 which defines an upwardly opening hook 308 which is engageable in hook 302 of the staff bag . engagement is accomplished by placing the base 16 of the carry bag into the receptacle 56 of the base of the staff component as seen in fig2 . applying downward manual force will depress plate 310 against springs 312 sufficiently to allow hooks 302 and 308 to engage . when the force is released , the spring 312 will maintain the bags in engagement at hooks 302 and 308 . in fig2 another attachment system is shown in which the carry bag 12 has a latch pin 220 with an annular groove 222 which is releasably receivable in inverted keyhole - shaped slot 225 in sleeve 60 of the staff bag component . it will be noted that the same or similar components have been designated with the same numerals throughout this specification . while the principles of the invention have been made clear in the illustrative embodiments set forth above , it will be obvious to those skilled in the art to make various modifications to the structure , arrangement , proportion , elements , materials and components used in the practice of the invention . to the extent that these various modifications do not depart from the spirit and scope of the appended claims , they are intended to be encompassed therein .
