CROSS REFERENCE TO RELATED APPLICATION 
     This application claims the priority of Norwegian patent application Ser. Nos. 20003362 and 20003363, filed on Jun. 27, 2000, and Norwegian patent application Ser. No. 20010432, filed on Jan. 24, 2001. 
     FIELD OF THE INVENTION 
     The present invention relates to the construction of a golf bag including a wheel assembly and optionally including supporting braces for supporting the golf bag in a substantially upright position. 
     DESCRIPTION OF THE RELATED ART 
     There are known a number of different constructions for golf bags, inter alia stiff and soft ones, and there are known several devices for mounting both straps and/or wheels as well as supporting braces on such bags. 
     A general consideration concerning such golf bags is that the bags are to occupy as little space as possible when disassembled/demounted while at the same time being capable to include the golf clubs as well as the wheels and supporting braces. 
     From e.g. SE B 3.836.683 and U.S. Pat. No. 4,792,152 there is known a golf bag with an opening in its one end and a solid and impenetrable bottom in its opposite end, wherein the bag comprises a stiff frame and a holster and wherein the bag is equipped with demountable rolling wheels which, when disassembled, may be received coaxially with the frame in its bottom part. The rolling wheels are designed to be mounted in a demountable fashion on the frame, and the frame is, from its opening and to its bottom, equipped with a guiding rail for a slideable handle, and receiving the demounted wheel braces, respectively. However, although the wheels according to these constructions may be demounted and stored at the bottom or inside the golf bag, a general concern is that the accessibility of such wheels (as well as the different parts for the frame/carrier of the bag) is limited and the parts are cumbersome to handle when assembling the frame/carrier. 
     Consequently there exists a need for an improved golf bag wherein the frame and wheels are readily accessible for assembly and where the entire golf bag, when disassembled and demounted, holds up a minimum of space for transport in a convenient manner, and where the assembly of the golf bag frame together with the golf bag is done neatly and economically. 
     SUMMARY OF THE INVENTION 
     One of the aspects of the present invention is consequently to provide the golf bag with rolling wheels wherein the wheels are suited to be stored inside the bottom of the golf bag when disassembled and remounted in its storage mode, and where the golf bag furthermore includes an internal space to store struts for the wheels to be mounted onto the frame of the golf bag, and wherein the bottom section of the golf bag is formed as receiving cups which between their adjacent side walls have apertures that in is their dimensions and orientation correspond to spokes and hub in the demounted roller wheels, and preferably the roller wheels have spokes that protrude from the hub mainly in the form of a Y, and wherein the space between cups in the bottom part have a corresponding Y-shape.

     DETAILED DESCRIPTION OF THE INVENTION 
     With reference to  FIGS. 1–10 , and especially  FIGS. 1–4 , a rigid frame to be used in a golf bag according to the present invention comprises a top ring element  1  for the opening of the bag, a cup-formed bottom part  2  and an intermediate ring element  3  being located axially with respect to each other. The assembly comprises furthermore a number of axially placed walls  4 , 5 , 6 , 7  running from the top ring element  1  through the intermediate ring element  3  to the bottom part  2 . Two walls  4  converge towards each other from a central area around the axis of the frame to the external limit of the frame, wherein said external limit also is defined by e.g. the top ring element  1  and the intermediate element  3 . Two walls  5  diverge from each other from the central area towards the external limit, opposite with respect to first mentioned walls  4 , and the walls  4 , 5  are located symmetrically around a common plane of symmetry. The walls  6  and  7  are located between the walls  4  across from said plane of symmetry. Further cross walls may optionally be placed outside the walls  4  for further sectioning the volume of the bag, e.g. as indicated in dotted lines  6 ′, 7 ′ in  FIGS. 3 and 4 . The frame is surrounded by a rigid sheath or a soft or a semi-soft sheath  8 . The sheath  8 , being indicated by dotted lines, is secured conveniently to the frame. The walls  4 , 5 , 6 , 7  (and the optional further cross walls) limit, together wit the sheath  8  and the bottom part  2 , a number of rooms or pockets for storing golf clubs or other items. The central pocket serves for receiving a club with a relatively short handle, e.g. a putter, for a purpose to be explained infra under reference to  FIGS. 6 and 7 . 
     The bottom part is, in the indicated embodiment, formed as three cups  9 , 10 , 11  being reciprocally connected by an upper edge ring  12  and a hub part  13  which between their respective side walls include spaces which in their orientation and dimensions correspond to spokes  14 , and the hub  15  in the demountable wheels  16  of the bag ( FIG. 5 ). The height of the walls in the cups  9 – 11  is twice the width of the wheels  16 . The two wheels of the bag will thus, in their demounted mode, be pushed inside the bottom part  2  of the bag with spokes and hub housed in the spaces between the cups  9 – 11  in the bottom part. 
     According to the invention the frame is, from the opening and towards the bottom, equipped with leads or channels  17 ,  18 , respectively, for a extendable/retractable handle  19 , or for receiving a wheel strut  20  in the demounted mode. 
     The lead  17  for the extendable/retractable handle  19  may run from the top ring element  1  and well past the intermediate ring element  3 , whereas the leads  18  for the wheels  20  may run from the top ring element  1  to the intermediate ring element  3 . Immediately below the lower or inner end of the strut leads  18 , there is located mainly radially extending leads  21  running from the outer circumference of the intermediate ring element and inwards along the walls  5 , and serve for receiving one end of each wheel support  20 , whereas the wheels  16  of the bag with their hubs  15 , may be detachably mounted on pins at the opposite end of the supports/struts  20 . 
     The handle of the golf bag may preferably be located at the apex of the golf bag when the bag is placed in a reclined position with an angle to the ground, optionally when the golf bag is used as a pullcart. In this position the handle will be located diagonally opposite the wheels of the golf bag or the wheels of the frame, or will be located opposite the braces of the golf bag. By placing the handle in this position it is achieved the advantage the handle may be made smaller, and the handle may also be equipped with a plastic sheet or tarpaulin for protecting the golf clubs inside the bag against precipitation such as rain or snow. However, the handle may also be placed at any other convenient location, e.g. at the sides of the golf bag or optionally also as an addition to the frame to which the golf bag is mounted. 
     At the bottom or innermost in the central room being formed between the walls  4 , 5 , 6 , 7 , there is present a somewhat narrowed passage  22  ( FIG. 6 ) towards the hub part  13  in the bottom part  2  for positioning a release element  23  ( FIG. 7 ). When mounting the wheels  16  onto the cups in the bottom part  2 , the hub part  15  of the wheels pushes the release element  23  backwards. When releasing the wheels  16  from the bottom part  2 , the release element  23  is pushed out by using the handle of a golf club, e.g. a putter, a collar  23  on the release element, by acting on the edge of the narrowed opening  22 , preventing the release element to be pushed too far out. 
     In an alternative embodiment the golf bag according to the invention (or also a conventional golf bag comprising a rigid frame and a soft, semi-soft or stiff sheath and being equipped with a securing loop for a carrier strap) is equipped with at least one and preferably two extendable supporting legs being secured with a hinge to the bag or the frame. The supporting legs may include a resilient element, e.g. a spring, extending the legs and being secured by the fastening loop for the carrier strap for being pulled against the bag when operating the carrier strap. What mainly is characterising for this embodiment of the invention is that the supporting leg or legs is/are connected to the securing loop for the carrier strap through a wire or similar element which is led mainly diametrically or cordially through the upper part of the bag. In an alternative embodiment the securing loop is elongated with mutually parallel branches. Between the two branches of the securing loop there is place a glider whereto the wire is secured. This glider is designed for a sliding movement back and forth between the two parallel branches of the securing loop for loosening and tightening of the wire. 
     With reference to  FIGS. 11 and 12 , these figures show a schematic side view of the opening part of a golf bag with extendable supporting legs and a securing loop for a carrier strap, with the legs in a indrawn respective extended position. 
       FIG. 13  shows a frontal view of a securing loop with a glider for tightening the collecting wire for the supporting legs, whereas  FIGS. 14 and 15  show a side view of the securing loop in  FIG. 13  with the glider in each of the first and second positions, respectively. 
     On a golf bag in the form of a rigid sheath or in the form of a softer holster with a rigid frame, there is at the top opening  1 ′ of the bag, indicated with a dotted line, on one end arranged a securing loop  2 ′ for a carrier strap (not shown), and on the opposite side from the hinge securing point there are located two supporting legs  3 ′. When said legs are folded out from the bag, they will provide an adequate support for a bag standing in an inclined position. To prevent the supporting legs from spreading outwards when the bag is carried, the supporting legs  3 ′ are connected by e.g. a wire to the carrying loop  2 ′ for the carrier strap, so that the supporting legs  3 ′ are retracted towards the body of the bag when the bag is lifted by the carrier strap since the wire then will draw the legs in towards the bag body. The wire  4 ′ extends mainly diametrically or cordially through the upper part of the bag. When the bag again is placed on the ground, the legs may manually be extended or by there being placed a spring device  31 ′ between the bag and the legs, e.g. in connection with the legs&#39; hinges  32 ′. For preventing the legs  3 ′ from unintentionally being extended from the bag, e.g. during transport, it is convenient to provide e.g. a Velcro-strap on the bag near the free end of the support legs in their retracted, non-operative position. 
     The securing loop  2 ′ for the carrier strap is conveniently, as shown in more detail in  FIGS. 13–15 , formed elongated with reciprocally parallel branches  21 ′ between an outer, curved securing part  22 ′ for the carrier strap, and an inner end where the securing loop is hinged, at  22 ′, to the opening part  1 ′ of the bag. Between the two mutually parallel branches  21 ′ there is mounted a glider  5 ′ to which the wire  4 ′ is secured for displacement between an outer position where the wire  4 ′ through operating the securing loop  2 ′ may be loosened for extending the supporting legs  3 ′, and an inner position where the wire is tightened whereby the legs are withdrawn in towards the bag and wherein the glider  5 ′ may be locked with respect to the securing loop  2 ′. In the shown embodiment the glider is formed by two parts  51 ′, 52 ′ being mutually hinged at  53 ′ about an axis running across the parallel branches  21 ′ of the securing loop  2 ′, and so that the outer part  51 ′ of the glider  5 ′ in this locking position, lies along the inner part of the glider between and in locking position with the two parallel branches  21 ′ of the securing loop, whereas the external glider part  51 ′, when the glider is to be liberated, is turned outwards about the hinge  53 ′ and out from attachment to the securing loop branches  21 ′, whereby the glider may be displaced with respect to the securing strap.
