referring to fig1 - 3 , auxiliary bag 10 has a six - sided sleeve 12 that can be formed of leather , plastic or other appropriate materials , including a cloth tube reinforced with supporting struts . side faces 10b form an angle of about 120 degrees with the outside face 10a of auxiliary bag 10 . outside face 10a is parallel to rear face 10c . the outer face 10a of auxiliary bag 10 has a handle 36 . the upper part of auxiliary bag 10 has a reinforcing collar 14 . the bottom of auxiliary bag 10 has a cup - shaped boot 16 . boot 16 has a bottom portion 16a under an overhanging portion 16b . bottom portion 16a is sized and keyed to fit into pocket 18 . pocket 18 is a receptacle formed in base 20 of main bag 22 . main bag 22 has a main sleeve 24 whose perimeter is almost octagonal except for an auxiliary region 26 , which forms a concavity 26 bordered by ribs 28 . the upper end of main sleeve 24 is capped by a reinforcing collar 30 shown with partitions to allow segregation of golf clubs placed within the bag . a shoulder strap 38 is attached to the main bag 22 opposite region 26 . underlying shoulder strap 38 is a handle 40 , also mounted on main bag 22 . mounted in a lateral upper recess 32 of auxiliary bag 12 is a hook 34 , which is part of a holding means . another part of the holding means is eye 37 shown in fig2 as a u - shaped bracket riveted to reinforcing collar 30 between the ribs 28 in the auxiliary region 26 . in fig2 main bag 22 is shown leaning against a support bracket 42 , which is part of a golf cart ( either powered or hand drawn ). bracket 42 has a bag belt 44 designed to attach to a bag buckle ( shown hereinafter ) on the outer end of bracket 42 . referring to fig4 and 9 , main bag 22 is shown having a main buckle 46 , shown with a tab 48 reinforced with a grommet 50 . grommet 50 is held in eye 54 , which is riveted to the side of main bag 22 . a swivel joint 52 allows buckle 46 to roll 180 ° around a horizontal axis . buckle 46 is shown swung back to receive bag belt 44 from bracket 42 of the golf cart . opposite buckle 46 is a main strap 56 looped through a steel ring 58 . ring 58 fits through an eye 60 , riveted to the outside of main bag 22 . main strap 56 is shown passing through bag buckle 62 mounted on the golf cart bracket 42 . accordingly , by tightening strap 56 and belt 44 , main bag 22 can be secured to bracket 42 of the golf cart . the positions of strap 56 and buckle 46 can be exchanged when the buckle and belt on the golf cart are the reverse of that illustrated . such reversal normally exists between the right and left side of a motorized golf cart . the exchange of strap 56 and buckle 46 can be accomplished by undoing eyes 54 and 60 ( or by undoing elements 50 and 58 ). for example eyes 54 and 60 may be hollow split rings , each containing a slider that moves to close and open the split . alternatively , the eyes may be solid split rings , each having a sleeve that slides to close and open the split . still other embodiments may employ a ring having a hinged segment that swings open and closed . referring again to fig3 auxiliary bag 10 is shown mounted against main bag 22 . previously mentioned main strap 56 is now shown wrapped across the auxiliary bag 10 underneath handle 36 . the end of strap 56 is shown fastened in main buckle 46 . buckle 46 has for this reason been swung toward auxiliary bag 10 . referring to fig6 and 8 , previously illustrated main base 20 is shown having an approximately octagonal footprint . a main receptacle 64 in base 20 is encircled by a main rim 66 having six sides , two pairs of them being parallel . pocket 18 ( also referred to as an auxiliary receptacle ) is encircled by an auxiliary rim portion 68 . the rim portion 68 is at a lower elevation than main rim 66 . auxiliary boot 16 is shown as a cup - shaped member , namely a hollow polygonal prism . the overhanging portion 16b has a larger perimeter and therefore connects to lower portion 16a by means of a transition , shown as a shelf 16c . base 20 has a number of drain holes 20a for draining . similarly , boot 16 has a hole 16d for draining as well . fig8 shows auxiliary sleeve 12 inserted into the overhanging portion 16b of boot 16 to abut the shelf 16c . also , main sleeve 24 is shown inserted into the main receptacle 64 of base 20 . to facilitate an understanding of the principles associated with the foregoing apparatus , its operation will be briefly described . the golfer may arrive carrying the golf bag assembled as shown in fig3 using the shoulder strap 38 . clubs such as the putter , nine iron , sand wedge and chipping wedge may be placed in auxiliary bag 10 . the other clubs and accessories may be placed in the various compartments in main bag 22 . when the bag is placed in a golf cart , strap 56 may be undone from buckle 46 . the auxiliary bag 10 will not release immediately from main bag 22 since hook 34 is still captured in eye 37 . the bag may next be arranged as shown in fig9 . specifically , the shoulder strap 38 can be placed around the bracket 42 . then the main buckle 46 can be rolled around a horizontal axis and swung backwards to the position shown in fig9 . in this position , bag belt 44 can be inserted through the main buckle 46 as shown . at the same time , strap 56 can be inserted through the bag buckle 62 on golf cart bracket 42 . strap 56 and belt 44 can then be tightened to secure the golf bag against bracket 42 . at this time , strap 56 no longer restrains auxiliary bag 10 . accordingly , auxiliary bag 10 can be removed by lifting it with handle 36 so that hook 34 disengages eye 37 . the golfer may then carry auxiliary bag 10 to the green where the various clubs contained inside auxiliary bag 10 can be used . after such use , the auxiliary bag 10 can be returned to the main bag by inserting the lower boot portion 16a ( fig1 ) into the pocket 18 ( fig2 ) of the main bag 22 . since boot 16 is keyed to the pocket 18 , auxiliary bag 10 will always be oriented in the correct direction with handle 36 pointing outwardly and with hook 34 oriented towards the eye 37 . once the auxiliary bag 10 is positioned in approximately the correct position , it is lowered to place hook 34 into eye 34 . overhanging portion 16b then abuts the rim of pocket 18 . when the golfer is finished , the buckles 46 and 62 ( fig9 ) may be undone . the bag is not yet ready for transport since hook 34 is not secure enough . accordingly , buckle 46 is returned to its original position so that strap 56 can be inserted into buckle 46 , thereby securing auxiliary bag 10 to main bag 22 . the strap 56 provides a high degree of security from accidental removal . with the strap 56 in the transport configuration , the bag combination can be safely carried , even with handle 36 . referring to fig1 and 11 , previously illustrated reinforcing collars 14 and 30 are shown without the hook and eye described above . instead , the inside face of collar 14 is shown carrying a magnet 70 . reinforcing collar 30 is shown with a metal plate 72 . in some embodiments , the magnet and plate can be reversed . alternatively , a pair of magnets can be used instead . the magnet and plate ( or magnet to magnet combination ) is referred to as a complementary pair of magnetically attractive devices . accordingly , collars 14 and 30 can be secured by the magnetic attraction between magnet 70 and metal plates 72 . this arrangement allows the auxiliary bag to be removed without the lifting necessary when a hook is used . referring to fig1 , the previously mentioned magnets are replaced with a pair of velcro pads 74 and 76 . pad 74 is mounted in a recess in reinforcing collar 14 by gluing , riveting or otherwise . pad 76 is shown mounted on the face of reinforcing collar 30 by means of rivets 78 , although in some embodiments pad 76 may be glued instead . pads 74 and 76 will operate similarly to the previously mentioned magnet and metal plate and are referred to as a complimentary pair of adhering pads . referring to fig1 , reinforcing collar 14 of auxiliary bag 10 is shown secured to collar 30 of main bag 22 by a strap 80 . strap 80 is shown having a snap 82 that attaches to an underlying stud ( not shown ) on reinforcing collar 30 . the opposite end of strap 80 is riveted to the opposite side of reinforcing collar 30 . alternatively , snap 82 can be replaced with velcro pads or other fastening means . strap 80 may replace the previously illustrated holding means , i . e . the velcro pads , the magnet and the hook . alternatively , the strap 80 may work with those holding means and replace the previously illustrated transport strap ( strap 56 of fig3 ). referring to fig1 , 15 and 16 , the previously illustrated auxiliary bag 10 is shown outfitted with a u - shaped assembly 84 . assembly 84 has a cross member 86 connecting to a pair of legs 88 . assembly 84 is journalled to auxiliary bag 10 with trunions 90 . trunions 90 fit into matching grommet holes in the side of auxiliary bag 10 . legs 88 ( as shown in fig1 ) make an angle of about 120 ° with cross member 86 . cross member 86 acts as a stop to restrict the angular rotation of legs 88 to the approximate 90 ° degrees shown in fig1 . because trunions 90 are not mounted on the widest portion of bag 10 , legs 88 must spread outwardly to be deployed as shown in fig1 . this spreading increases the stability of the bag . thus by rotating the legs outwardly as shown in fig1 ( in full line ) the bag 10 may be placed on the ground with the collar 14 raised to facilitate removal of clubs from the auxiliary bag 10 . it is to be appreciated that various modifications may be implemented with respect to the above described preferred embodiments . while the main and auxiliary bags are shown having the general shape of a polygonal prism , in other embodiments they may have curved perimeters including elliptical perimeters . also , the bags may be attached by various means including elastic cords ( bungee cords ), and fasteners of various types such as those found in luggage , etc . also , the main and auxiliary bags can have accessory pockets of various sizes for holding golf balls , gloves , clothing , etc . also , the bags may have more handles , fewer handles or no handles at all . moreover , the pocket for holding the bottom of the auxiliary bag need not have a shape exactly matching that of the auxiliary bag and need not be keyed . furthermore , the auxiliary bag need not have an overhang to limit the extent to which the auxiliary bag descends into the pocket . also , the various dimensions illustrated and the material used can be varied depending upon the number of clubs to be carried , and the desired physical strength , durability and weight of the bag . also , while the auxiliary bag is shown smaller than the main bag , it need not be so . obviously many modifications and variations of the present invention are possible in light of the above teachings . it is therefore to be understood that within the scope of the appended claims , the invention may be practiced otherwise than as specifically described .
