Title: Bicycle Support and Packaging Structure and a Bicycle Packaging Method

Description:
TECHNICAL FIELD 
     The present invention relates to a bicycle support and packaging structure having the features of the first part of claim  1 , and to a method for packaging a bicycle for transportation purposes having the features of the first part of claim  18 . 
     BACKGROUND 
     Bicycling is an activity that is becoming more and more popular. Bicycles are also becoming increasingly specialized for different activities, e.g. conventional bicycles, city bikes, mountain bikes, downhill bicycles and racing bicycles. Many bicycles are even customized, i.e. individually adapted for a specific individual. The bicycles are hence often technically elaborate and expensive. Bicycles therefore need to be stored in a safe manner, in some instances without demanding too much space and without risking to be damaged in times of no use and it has become common that individuals transport their bicycles, e.g. for performing a bicycling activity, to bring the bicycle, or to have it transported separately. Therefore there is an increasing demand for a means and a method allowing storing and transportation of bicycles in a safe manner, assuring that the bicycle is well protected during storing and transportation, and also allowing packaging and transportation of the bicycle in an easy manner. 
     Several different kinds of bicycle bags or cases have been proposed. WO 2008/109986 and U.S. Pat. No. 4,991,715 show bicycle travel/storage bags or cases. Bicycle bags with hard covers are known. They, however, often suffer from the disadvantage of being bulky and heavy. 
     Bags and cases are also known which comprise a reinforcing shell and a frame structure for protecting the bicycle and to keep it safe in a given position. However, all these known devices suffer from various drawbacks. Either they are heavy and bulky, or they are lightweight devices with none or only a very poor protective capability. Many of these devices are also complex, and it requires a lot of time and skill to demount and arrange the bicycle in the transportation structure. In some cases the bike has to be demounted to a great extent, requiring even more time and skill for demounting, and, subsequently, after transportation, mounting it again. It should be noted that known bags or cases, which have a comparatively good protective capability, are large, heavy and bulky, which is impractical not only for transportation and handling purposes but also when it comes to storing the bag or case when not in use. 
     In WO 2014/003629 a bicycle transportation support and packaging structure is proposed which has the advantage of being a lightweight device which also provides for a good protection of the bicycle. Furthermore it is not space demanding or bulky during storing. A disadvantage with this known structure is, however, that it is too complex for allowing a satisfactory fast and easy arrangement of the bicycle in the structure, and for removing and mounting the bicycle after transportation. Further, stability and protective capability still need to be increased. 
     SUMMARY 
     It is therefore an object of the present invention to provide an improved bicycle support and packaging structure as initially referred to through which one or more of the above mentioned drawbacks are overcome. It is also an object of the invention to provide an improved method for packaging a bicycle for storing or transportation purposes as initially referred to through which one or more of the above mentioned problems are solved. 
     It is a particular object of the invention to provide a bicycle support and packaging structure which is easier to handle than hitherto known structures, and which provides for a good protection of the bicycle. It is particularly an object to provide a transportation support and packaging structure which is a lightweight structure. It is a particular object to provide a support and packaging structure which is demountable, and which can be easily mounted for transportation of a bicycle, and which further, at completed transport of the bike, easily can be demounted, and which in a demounted state is not bulky. 
     It is a particular object of the invention to provide a bicycle support and packaging structure which is flexible and easily adaptable for different bicycles/bicycle sizes. 
     It is another particular object to provide a support and packaging structure which is easy and cheap to fabricate. Still further it is an object to provide a support and packaging structure which can be used for bicycles of different types and having different sizes and dimensions. 
     Most particularly it is an object to provide a bicycle support and packaging structure which is easy to use in that it does not require any extensive demounting of the bicycle for safe transportation. 
     Moreover it is a particular object to provide a bicycle support and packaging structure which is capable of keeping a packaged bicycle in place, and which also is easy to transport, and even to move manually shorter distances in a mounted state with a bicycle therein. 
     Therefore a bicycle support and packaging structure as initially referred to is provided, which further has the characterizing features of claim  1 . 
     Therefore also a method having the initially features which further has the characterizing features of claim  18 . 
     Advantageous embodiments are given by the appended dependent claims. 
     It is a particular advantage of the invention that a bicycle transportation support and packaging structure is provided which, at the same time as providing for excellent protection of a bicycle arranged therein, has a low weight, allows for particularly fast and easy arranging the bicycle in the structure for transportation, and which can be demounted for storing in intermediate time periods without demanding much space, i.e. when it is not used for transportation purposes, but also for storing, shipping and delivery purposes of bicycles e.g. after fabrication.

     DETAILED DESCRIPTION 
       FIG. 1  is a schematic view of an embodiment of a bicycle support and packaging structure  100  without any covering arrangement, inner protective arrangement, wheel holding means etc. and illustrates how a partly demounted bicycle is arranged in a bicycle support and packaging structure  100  according to one embodiment of the present invention. In  FIG. 1  a cover frame structure  50  is illustrated, although the present invention also covers embodiments without any cover frame structure, or with other cover frame structures. 
     It should be clear that the bicycle (transportation) support and packaging structure  100  advantageously, but not necessarily, also comprises a covering arrangement, a shell, or a casing, (see  FIG. 7 ) and preferably also an inner protective arrangement (see  FIG. 6 ), not shown in  FIG. 1  for reasons of clarity. Different kinds of covering arrangements or casings, as well as optional protective arrangements, can be used, having different properties, as will be further described and exemplified below. The properties may be different for example depending on requirements, needs and preferences, and e.g. depending on the most relevant transportation mode, e.g. transportation by car, by bus, by airline, train or boat, costs etc. In some cases there are no covering arrangements and/or protective arrangements. 
     For mounting of the bicycle support and packaging structure onto a partly demounted bicycle, the wheels, the handlebar and the handlebar stem are removed to allow for arranging a handlebar adapter connecting arrangement  25  of a handlebar adapter arrangement  20  in place of a handlebar and a handlebar stem. The wheels (not shown in  FIG. 1 ) are kept separately, as well as other parts, e.g. chain, pedals etc. 
     The packaging and support structure  100  also comprises a saddle holder  10  for receiving the saddle mounted on a bicycle. The saddle holder  10  and the handlebar adapter arrangement  20  are connectable to, or form part of, a support or carrier structure  30 . The saddle holder  10  comprises a saddle receiving member  11  used for reception of a saddle  65  of a bicycle disposed upside down, e.g. a cushioning or concave member, and a fastening means  13 . The fastening means  13  may e.g. comprise a strap or similar for securing the saddle  65  in place on the saddle receiving member  11 . 
     In the shown embodiment, the support or carrier structure  30  comprises a support frame structure  30 . The saddle holder  10  is connected to a saddle holder connector distance element  12 , which is detachably securable to the longitudinal support frame elements  31 , 32  of the support frame structure  30  by means of screws or bolts (not shown). Each longitudinal support frame element  31 , 32  comprises a number of through holes  311 , 321  for taking up said screws for securing the saddle holder connector distance element  12  through screw holes (not shown) provided in the outer ends of the saddle holder connector distance element  12 . The screw holes in the saddle holder connector distance element  12  are particularly provided in end elements  115 , 115  (see  FIG. 2 ) provided at the outer ends of the saddle holder connector distance element  12 . 
     Depending on bicycle frame dimension the appropriate holes  311 , 321  in the longitudinal support frame element  31 , 32  can be selected with respect to corresponding appropriate holes  311 , 321  selected for a corresponding handlebar adapter connector distance element  22 . The strap  13  is connected to a bicycle saddle  65  disposed on the saddle receiving member  11 . The saddle receiving member  11  may in different embodiments be detachably or fixedly connected to the saddle holder connector distance element  12 . 
     In a similar manner the handlebar adapter arrangement  20  comprises, or is fixedly or detachably connected to, a handlebar adapter distance element  22 , the outer ends of which are provided with end elements  225 , 225  with screw holes for reception of screws for introduction into selected holes  311 , 321  in the longitudinal support frame elements  31 , 32 . Thus the distance between the saddle holder  10  and the handlebar adapter arrangement  20  can be selected through selection of appropriate holes in the longitudinal support frame elements  31 , 32  for fastening of the respective connector distance elements  12 ,  22 . 
     The handlebar adapter arrangement  20  further comprises a handlebar adapter holder element  23  comprising a block, plate or similar  23 , e.g. an integral block with a central recess or opening for reception of a handlebar adapter connecting arrangement  25 . By means of a screw  27  (see  FIG. 2 ) the handlebar adapter connecting arrangement  25  can be fixed in the opening of the handlebar adapter holder element  23  when said handlebar adapter connecting arrangement  25  has been fastened to a fork tube of a bicycle front fork, such that the fork tube is fixedly and steadily clamped in the handlebar adapter holder element  23 . In an alternative embodiment the handlebar adapter holder element  23  comprises no slot but securing takes place by means of one or more straps or similar. 
     Preferably the saddle holder  10  and the handlebar adapter arrangement  20 , particularly the handlebar adapter holder element  23 , are disposed symmetrically with respect to outer ends of the saddle holder connector distance element  12  and the handlebar adapter distance element  22  respectively. In an alternative embodiment the saddle holder  10  and the handlebar adapter connecting arrangement are disposed asymmetrically with respect to the outer ends of the saddle holder connector distance element  12  and the handlebar adapter distance element  22  respectively, e.g. if both bicycle wheels are to be kept on one and the same side of a packaging structure with a covering arrangement, and/or in case further parts of the demounted bicycle or other items are to be transported along with the bicycle, e.g. in pockets in a covering arrangement. 
     The saddle holder connector distance element  12  and the handlebar adapter distance element  22  are for example made of aluminium, plastic, steel, carbon steel or any other appropriate material, and are advantageously adapted to be releasably connectable to the support frame structure  30 , and may have the same dimensions, e.g. being identical. 
     The bicycle support and packaging structure  100  further advantageously comprises a cover frame structure  50  comprising a plurality of tubular elements  60  which are interconnected to form a first and a second cover frame section  51 , 52  adapted to laterally, upwards, rearwards and frontwards surround a bicycle frame mounted in the support and packaging structure  100  in an upside down position, when mounted onto the saddle holder  10  and the handlebar connecting arrangement  20  and act as respective, parallel side cover frame sections  51 , 52 . The cover frame sections  51 , 52  in the shown embodiment each comprises a number of straight first tubular elements  60  having a circular cross-section with a first diameter D1, and a number of straight second tubular elements  60  having a circular cross-section of a second diameter D2, said first diameter D1 in the shown embodiment being the same as said second diameter D2, and the interconnection between straight tubular elements e.g. being enabled through the use of sleeve elements  66  as will be further explained with reference to  FIGS. 5A-5D  below; and the position of a first tubular element with respect to a second tubular elements, or vice versa, is then secured by means of slidably mounted sleeves  66  which in turn can be secured by means of a spring biased element with protruding pins or similar that can be actuated through openings in the tubular elements  60  or in any other appropriate manner (see also  FIG. 4  below). In the optional cover frame structure  50  shown in  FIG. 1 , the straight first and second tubular elements have the same dimensions. 
     In alternative embodiments said first diameter D1 somewhat exceeds said second diameter D2 and no sleeves  66  are needed. Still further the diameters may be the same for all tubular elements, and they may be interconnected through any other appropriate elements. 
     A plurality of interconnecting elements  53 , e.g. connection bars, are hingedly connected via first and second hinged connector elements  531 , 532  to the tubular elements  60  via as will be further discussed below, are provided for interconnection of the two side cover frame sections  51 , 52 . 
     The bicycle support and packaging structure  100  still further comprises lower profile elements  41 , 42  serving the purposes of interconnecting the free outer, front and rear, ends of longitudinal support frame elements  31 , 32  of the support frame structure  30 , and in this embodiment providing a support for front and rear free outer ends of lower tubular elements  61 , 61 , 61 , 61  of the cover frame structure  50  and providing a protection against external shocks and friction of the entire support and packaging structure  100  during transportation. The latter is enabled through mounting said lower profile elements  41 , 42  outside the covering arrangement as will be more thoroughly discussed below, such that they will be exposed externally instead of the covering arrangement. Preferably said lower profile elements  41 , 42  are made of a resistant material, e.g. metal, for example Al-profiles, steel profiles or similar, or of plastic or carbon fiber. 
     At least one of the lower profile elements, here the rear lower profile element, is adapted for reception of roller wheels  69 , 69  that can be fastened thereto by means of screws or bolts  411 , 411 ; said screws or bolts in an advantageous embodiment also serving the purpose of fastening the rear lower profile element  41  to the support frame structure  30 . The front lower profile element  42  is also connected to the support frame structure  30  by means of screws or bolts  421 , 421 . The front lower profile element  42  is in the shown embodiment provided with studs or supports  422 , 422 . The wheels may be fixedly or removably connected at the outer end portions of the lower profile element  41  in any appropriate manner. In alternative embodiments there are no roller wheels connected to the rear lower profile element  41 , but instead to the front lower profile element  42 , or to both. The roller wheels  69 , 69  serve the purpose of allowing the packaging structure with a bicycle in a partly demounted state to be rolled, pulled or pushed. In an alternative implementation the/a pair of roller wheels might be replaced by supports, e.g. allowing sliding of the packaging structure on a surface, e.g. balls of, or covered with, a low friction material (not shown). 
     The support and packaging structure  100  in the embodiment shown in  FIGS. 1 and 2  also comprises a bottom support plate  45  comprising substantially perpendicularly disposed inner flanges  453  and outer flanges  452  (see  FIG. 2 ) releasably and adjustably connectable to the longitudinal support frame element  31 , 32  of the support frame structure  30  by means of pins and/or screws or bolts  451  ( FIG. 2 ). The bottom support plate  45  also serves the purposes of acting as a support for free lower ends of tubular elements  60 , stabilizing the frame structure, and, since it in an advantageous embodiment is mounted outside a covering arrangement also as an external protection against shocks and wear during transportation. It preferably also is made of a wear and shock resistant material, e.g. metal, particularly it comprises a steel or Al-profile or plate, or is made of plastic or carbon fiber. 
       FIG. 2  shows the support frame structure  30  more in detail. Like elements bear the same reference numerals as in  FIG. 1 , some of which will not be further discussed with reference to  FIG. 2  since they have already been discussed with reference to  FIG. 1 . 
     The handlebar adapter holder element  23  may comprise a block or similar and is adapted for reception of a handlebar adapter connecting arrangement  25  in a central opening or recess  24  in the block or similar. The block  23  comprises a slot  26  through a wall thereof into the opening  24 . A through opening crosses the wall of handlebar adapter holder element  23  with the slot  26  and also the slot  26  for reception of a screw, bolt and nut or similar  27  serving the purpose of fixing/tightening a handlebar adapter connecting arrangement  25  disposed in the opening  24  of the block  23  when said handlebar adapter connecting arrangement  25  has been connected to a head tube of a handlebar fork such that it will be fixedly and steadily clamped in the handlebar adapter holder element  23 . 
     The outer ends of the handlebar adapter distance element  22  are provided with end elements  225 , 225  with screw holes for reception of screws into selected holes  311 , 321  in the longitudinal support frame elements  31 , 32 . 
     The longitudinal support frame elements  31 , 32  in the shown embodiment each comprises three interconnected elements  3   1 ,  3   2 ,  3   3 , which merely relates to an advantageous embodiment; they may alternatively comprise but two elements or even one, or more. The main reason for using e.g. three elements, is to reduce the length of the elements allowing a demounting into shorter elements for packing and storing purposes. With such an implementation it is even possible to store the entire bicycle transportation support and packaging structure  100  in a bag with the dimensions of e.g. 30 cm×30 cm×40 cm. 
     The saddle receiving member  11  detachably or fixedly connected to the saddle holder connector distance element  12  can be of many different shapes, have different dimensions and be of different appropriate materials for receiving a saddle, and e.g. comprise a somewhat resilient damping material and/or adapted to a saddle shape etc. 
     The handlebar adapter connecting arrangement  25  preferably comprises a cylindrical connector element  25   1  with a diameter slightly exceeding that of a head tube of a handlebar fork and having a height exceeding the height thereof, e.g. 5 cm or similar, which exceeds the height of most bicycle stems. When a handlebar and a handlebar stem are removed from a bicycle, and replaced by the handlebar adapter connecting arrangement  25 , in one end thereof comprising a washer  28  with an opening for a screw, e.g. with an M6 threading as standardized for most bicycles, when screwing in the screw, the fork of the bicycle will be forced upwards, into the cylindrical connector element  25   1  and secured in place. 
     Such an embodiment will be more thoroughly explained with reference to  FIG. 3A . An alternative handlebar adapter connecting arrangement  25 ′ comprising also a washer in the opposite end of the cylindrical connector element, and intended for another type of bicycle fork, e.g. for a so called downhill bicycle, is shown in  FIG. 3B  below (for illustrative purposes illustrated also in  FIG. 2 , where a dashed leading line indicates that it is not necessary in an embodiment as in  FIG. 3A , and a cylindrical connector element  25   1  as in  FIG. 2 ). 
     The bottom support plate  45  comprises substantially perpendicularly disposed inner flanges  453  and outer flanges  452  releasably and adjustably connectable to the longitudinal support frame element  31 , 32  of the support frame structure  30  by means of at least one screw or bolt  451  and pins into element  3   3  screws or bolts. 
       FIG. 2  also shows the lower profile elements  41 , 42  somewhat more in detail, and in the present embodiment an external transverse wall  401 , 401  has a length corresponding to and somewhat, for mounting purposes, exceeds the distance between outer sides of the longitudinal support frame elements  31 , 32  when assembled to form the support frame structure  30 , a bottom wall  402 , 402  orthogonal to said external transverse wall  401 , 401 , and edge walls  403 , 403 , 403 , 403  for reception of said screws, bolts or similar  411 , 421  and interconnecting the outer edges of said external transverse walls  410  and said bottom walls  402 . 
       FIG. 2A  shows an alternative embodiment of a support frame structure  30 A. Like elements bear the same reference numerals as in  FIGS. 1 and 2 , or are not referenced, and will not be further discussed with reference to  FIG. 2A  since the functioning is the same. 
     A saddle holder or receiving element  10 A and a handlebar adapter arrangement comprising a handlebar adapter receiving element  20 A are connectable to, or form part of, the support frame structure  30 A. The saddle holder  10 A comprises a saddle receiving member  11 A fixedly or releasable connected to, or integrated with or received in, the saddle holder (connector) distance element  12 A for reception of a saddle  65  of a bicycle disposed upside down, and e.g. comprises a cushioning or concave member, and a fastening means (not shown). The fastening means may e.g. comprise a strap or similar for securing the saddle  65  in place on the saddle receiving member  11 A or the saddle holder distance element  12 A. 
     In this embodiment no element corresponding to the handlebar adapter holder element  23  of  FIG. 2  is needed, but instead the handlebar adapter distance element  22 A is adapted for reception of a handlebar adapter connecting arrangement  25 A (substantially similar to any one of the handlebar connecting arrangements described in  FIGS. 2, 3A-3D ) by means of a through, elongate slot  24 A provided in the handlebar adapter distance element  22 A and which comprises a central circular hole or opening portion  24 A′ in an upper plate of the handlebar adapter distance element  22 A and adapted to receive a handlebar adapter connecting arrangement  25 A such that the edge of the, here, circular central hole or opening  24 A′ can enter a circumferential groove or notch  25 B in the block or similar (the groove  25 B in  FIG. 2A ). The groove in which the edge is received edge is not visible, but in the shown embodiment it is similar to a further groove  25 B, which grooves  25 B, 25 B are located at a distance from each other on the cylindrical outer surface of the handlebar adapter connecting arrangement  25 A. At an opposite, in a mounted state, lower, plate of the distance element  22 A the through slot  24 A centrally comprises or is extended into a circular opening or recess  24 A″ of a smaller diameter than the upper central hole or opening  24 A′, and it is adapted to receive a screw head of a handlebar adapter connecting arrangement  25 A, e.g. as described with reference to  FIGS. 3A-3D , reference numerals  280 , 280 ′. Through holes cross side walls of handlebar adapter distance element  22 A interconnecting the upper and lower plates of the distance element  22 A, across the slot  24 A. The holes are for reception of screws, bolts and nuts or similar  27 A, 27 A serving the purpose of fixing or tightening the handlebar adapter distance element  22 A slot  24 A, and the edges of the circular hole or opening, around the handlebar connecting arrangement  25 A. Thus, the edge of the circular central slot portion  24 A′ enter the groove  25 B of the handlebar connecting arrangement  25 A and hence clamps it in position. Hence the fork or fork tube of the bicycle will be fixedly and steadily clamped in the handlebar adapter distance element  22 A via the handlebar connecting arrangement  25 A. 
     The outer ends of the handlebar adapter distance element  22 A are provided with end elements  225 , 225  with screw holes for reception of screws into selected holes  311 , 321  in the longitudinal support frame elements  31 A, 32 A such that the location of the distance element can be appropriately selected with respect to the bicycle frame. The handlebar adapter distance element  22 A is preferably made of a tubular profile element of a rectangular, square-shaped or any other appropriate cross-sectional shape, or alternatively it may be massive. 
     The longitudinal support frame elements  31 A, 32 A in the shown embodiment each comprises three interconnected frame sections  3 A, 3 B, 3 C; they may alternatively comprise but two frame sections or even one, or more. The main reason for using e.g. three sections is to reduce the length of the elements allowing them to be demounted into shorter elements for packing and storing purposes. Each outer frame section  3 A, 3 A, 3 B, 3 B comprises two interconnected L-beams, which are connected in such a manner that a leg of one L-beam is disposed on a leg of the other L-beam to form a bottom section, and the other legs or walls of the respective L-beams each form a wall section, an inner and an outer wall section extending in parallel so that an U-shaped beam is formed, upwards open and adapted to receive lower leg sections  61  of a cover frame structure; see e.g.  FIG. 4 . Two outer frame sections  3 A, 3 A; 3 B, 3 B respectively are interconnected by means of a respective intermediate frame section  3 C, 3 C comprising an U-beam or two interconnected L-beams preferably with legs of the same length and dimensions as the legs of the outer frame sections, or slightly larger legs than the legs of the outer frame section beams, and are mounted e.g. by means of screws, nuts and bolts or similar, such as to surround said legs of the outer frame sections in an overlapping region at respective inner, one another facing, ends of the first and second sections, and releasably connected thereto by means of screws, or bolts and nuts or similar in order to make the length of the frame structure  30 A, i.e. the lengths of the longitudinal support frame elements  31 A, 32 A, adjustable. Preferably the legs of the U-beams, or of the L-beams, forming the outer frame sections  3 A, 3 A, 3 B, 3 B and the intermediate frame sections  3 C, 3 C which face corresponding legs of an opposite longitudinal support frame element  31 A, 32 A, or the bicycle frame in a mounted state of the structure, are adapted to be arranged at an inner side of a protective arrangement  80  (see e.g.  FIG. 6 ), whereas the legs of the U-beams, or of the L-beams, forming the outer frame sections  3 A, 3 A, 3 B, 3 B and the intermediate frame sections  3 C, 3 C which face away from the bicycle frame in a mounted state of the structure, are adapted to be arranged at an outer side of the protective arrangement  80 . 
     The intermediate frame sections  3 C, 3 C are preferably mounted to the outer frame sections  3 A, 3 A, 3 B, 3 B by means of screws or bolts and nuts through the bottom of the U-shaped beams, or through the legs forming the bottom of the U-shaped beams, at appropriate, preferably selectable locations. 
       FIG. 2A  also shows alternative embodiments of lower profile elements  41 A, 42 A of which in the present embodiment at least one also forms a handle. At least one of the lower profile elements  41 A, 42 A is connected to an outer L-beam of the first and/or second frame sections forming an outer L-beam of the U-shaped element by means of screw, bolts an nut or similar and is arranged to form a handle. In such an embodiment the outer L-beam is displaced with respect to an inner L-beam to which it is connected to provide the U-shaped section, such as to protrude and leave room for the attachment of the outer end of the lower profile element  41 A, 42 A, and also to provide a distance between said lower profile element  41 A, 42 A and the packaging structure to allow for gripping the handle. In some embodiments both, in other embodiments only one of, the lower profile elements  41 A, 42 A is/are adapted to form a handle, and e.g. is provided with an external surface shaped or in any appropriate way adapted to function as a comfortable handle, preferably of a circular or similar cross-section, and optionally provided with additional gripping features, or gripping adapted shaped element or material. Either or both of the of the lower profile elements  41 A, 42 A may be provided with wheels, independently of also acting as a handle or not. 
     In this embodiment there is no bottom support plate as in  FIG. 2 , particularly due to the intermediate reinforcing and supporting and protecting section  3 C, which also provides an external protection to wear, shocks, friction etc. 
     The handlebar adapter connecting arrangement  25 A may be of any type substantially as described with reference to  FIGS. 3A-3D , however, it is provided with e.g. circumferential grooves  25 B. 
       FIG. 2B  schematic view from above of the handlebar adapter distance element  22 A of  FIG. 2A  showing the slot  24 A with the upper central hole or opening  24 A′ in the upper plate (referring to a mounted state) of the distance element, the smaller, lower central hole or opening  24 A″ in the lower plate of the distance element, and the heads of the adjustment screws  27 A, 27 A for tightening the openings/the slot and clamping the handlebar connecting arrangement  25 A as discussed with reference to  FIG. 2A . 
       FIG. 3A  schematically illustrates a single crown fork  250  from which the handlebar and the handlebar stem have been removed and replaced by a handlebar adapter connecting arrangement  25  comprising a cylindrical connector element  25   1 , a washer  28  and a screw  28  for fastening the handlebar adapter connecting arrangement  25  to the fork tube of the single crown fork  250 . When the screw  280  is tightened, the single crown fork tube will be drawn up due to the internal threading in the fork tube, and be secured. The handlebar adapter connecting arrangement  25  connected to the fork tube of the single crown fork  250  can then easily, when the bicycle frame is turned upside down, be introduced into the handlebar adapter holder element  23 . 
       FIG. 3B  is an enlarged view more clearly showing the handlebar adapter connecting arrangement  25  comprising the cylindrical connector element  25   1 , the washer  28  and the screw  28 . 
       FIG. 3C  schematically illustrates a dual crown fork  250 ′ from which the handlebar and the handlebar stem have been removed and replaced by a handlebar adapter connecting arrangement  25 ′ comprising a cylindrical connector element  25   1 ′, a washer  28 ′, a lower end washer  29 ′ and a screw  28 ′ for fastening the handlebar adapter connecting arrangement  25 ′ to the fork tube of the dual crown fork  250 ′. The lower end washer  29 ′ is provided to serve the purpose of a distance element, while, since the fork is a dual crown fork, the fork tube need not be drawn up and kept in place as for a single crown fork, and when the screw  280 ′ is tightened, the fork tube is simply connected to the handlebar adapter connecting arrangement  25 ′ for, when turned upside down, being introduced into the handlebar adapter holder element  23 . 
       FIG. 3D  is an enlarged view more clearly showing the handlebar adapter connecting arrangement  25 ′ comprising the cylindrical connector element  25   1 ′, the washer  28 ′, the lower end washer  29 ′ and the screw  28 ′. 
     It is an important advantage of preferred embodiments of the invention that handlebar adapter connecting arrangement is adapted to be connected to the fork head tube since the dimensions, i.e. the size of the diameter of the fork tube, generally is standardized for most bicycles, as opposed to the diameter of e.g. 
     the handlebar stem. 
     It is an advantage of the invention that the handlebar adapter ensures that the fork remains in place. The handlebar adapter connecting arrangement should be mounted before the bicycle is turned upside-down for connection to saddle holder  10  and the handlebar holder element  23 . The handlebar adapter connecting arrangement  25  maintains the position of the fork with respect to guide bearings of the frame, which otherwise might fall apart (for a single crown fork). 
       FIG. 4  is a more detailed illustration of a cover frame structure in an assembled state according to one embodiment of the invention. The first and second cover frame sections  51 , 52  are identical except for the first and second hinged connector elements  531 , 532  being arranged thereon, which are so arranged that a first connector element  531  on one of the frame sections is arranged to cooperate with a second connector element  532  disposed at a corresponding location on the other frame section.  FIG. 4  thus schematically illustrates the cover frame structure  50  comprising a plurality of tubular elements  60  which are interconnected to form the first and a second frame sections  51 , 52  adapted to laterally, upwards, rearwards and frontwards surround a bicycle frame in an upside down position, when mounted onto the saddle holder  10  and the handlebar adapter connecting arrangement  20  (see  FIGS. 1, 2 ). The frame sections  51 , 52  in the shown embodiment each comprises a number of first tubular elements  60  having a circular cross-section with a first diameter D1, and a number of second tubular elements  60  having a circular cross-section of a second diameter D2, said first diameter D1 in the shown embodiment being similar to the second diameter, and tubular elements  60  being similar, in other embodiments the first diameter D1 somewhat exceeds said second diameter D2 for alternatingly disposed tubular elements. 
     In some embodiments the first and second tubular elements have a similar diameter. Then, in one embodiment the position of a first tubular element  60  with respect to a second tubular elements  60  in, or vice versa, is secured by means of slidably mounted sleeves  66  which in turn can be secured by means of a spring biased element  68  (see  FIGS. 5A-5D ) with protruding pins  67  (see  FIG. 5D ) or similar that can be actuated through openings in the tubular elements  60  or in any other appropriate manner. Thus, for mounting of a frame section  51 , 52  tubular elements  60 , 60  of a same diameter, e.g. D2, are introduced into slidably mounted sleeves  66  of a somewhat larger diameter, e.g. D1, which in turn can be secured by means of the spring biased element  68 . Alternatively any other kind of tubular element connecting means are used, comprising a respective receiving portion for each of two tubular element ends, or in some embodiments, also or alternatively, or for but two tubular elements intended to be interconnected such as to form an angle, e.g. 90°, with each other, such as e.g. a tubular element  60  and an interconnecting element  53  as illustrated in  FIG. 4 . 
     In  FIG. 4  a plurality of interconnecting elements  53  are hingedly connected via first and second hinge connector element  531 , 532  to the tubular elements for interconnection of the two side cover frame sections  51 , 52 . 
     The side cover frame sections  51 , 52  also comprise bent tubular elements  62 , 63  which comprise first and second corner elements, in advantageous embodiments made of metal, e.g. Al, carbon fiber, plastic or any other appropriate resistant material. In alternative embodiments all tubular elements may be made of such resistant material; in still other embodiments all tubular elements, including the corner elements are made of plastic. The bent tubular elements  62 , 63  are bent so as to form a smooth bending angle, and here have a cross-section with a smaller diameter, e.g. D2, and being adapted to, at each outer end, be connected to a first tubular element  60  of a larger diameter through introduction into such elements  60 . Alternatively the have the same diameter as the straight tubular elements. The bent tubular elements  62 , 63  may in alternative embodiment be similar and also comprise a same bending angle. 
     The side cover frame sections  51 , 52  are thus formed through assembly of tubular elements  60 , 62 , 63  so as to form an upper portion  71 , a first side portion  73 , a second side portion  74 , a front portion  75  and a rear portion  76  of the cover frame structure  50 . 
     The first and second side cover portions  73 , 74  are formed by the planes formed by a plurality of assembled straight tubular elements  60  ( 61 ) and bent, interconnecting, corner tubular elements  62 , 63 . Each side cover portion  73 , 74  here comprises an upper section  711  comprising a number of tubular elements  60 , front and rear legs  731 , 734  and intermediate legs  732 , 733 , each leg here comprising assembled tubular elements  60 . 
     The lower tubular elements  60  of the respective first and second side cover portions  73 , 74  (legs  731 , 732 , 733 , 734 ) have free sections  61  arranged to end at, or adjacent, the bottom support plate  45  and the lower profile elements  41 , 42  ( FIGS. 1, 2 ). 
     Alternatively the lower tubular elements  60  are connectable or securable, fixedly or detachably, e.g. securably, to the longitudinal elements  31 , 32  ( FIG. 2 ) of the support frame structure  30  and/or to the bottom support plate  45  and the lower profile elements  41 , 42 . The connection or securing, if any, may e.g. take place using insex screws, or in any other appropriate manner. 
     The upper tubular elements of the respective first and second side portions  73 , 74  are releasably connectable to each a bent tubular element  62 , 63  comprising a corner element, preferably of Al, but alternatively of plastic, steel, any other metal or plastic, and are e.g. secured by means of the first and second hinge connector elements  531 , 532 , or as discussed above, through any other tubular element connecting means, forming a separate element or an element fixedly, e.g. pivotally, or releasably, connectable to one or more tubular elements and/or interconnecting elements. 
     The first and second side cover frame sections  51 , 52  are releasably connectable via the connection bars  53  which in the embodiment shown  FIG. 4  are pivotally connected via a first hinge connector element  531  to some of the straight tubular elements  60 . The connection bars  53  are adapted to be releasably connectable to cooperating receiving hinge connector elements  532  which are fixedly or releasably, in some embodiments also pivotally, connected to other straight tubular elements  60 . The receiving hinge connector elements  532  may in some embodiments comprise sleeves having a cross-section adapted to the cross-section of the connection bars, but somewhat larger, such that the connection bars  53  can be introduced therein and e.g. retained by means of a tight coupling, or friction. 
     Hence, for mounting of the frame structure, the connection bars  53  are here pivoted so as to form an angle of substantially 90° with the tubular elements on which they are arranged and introduced into the cooperating sleeve  532 , or in some other appropriate way connected to the cooperating receiving element. Thus a frame structure  50  is formed by two parallel side cover frame sections  51 , 52  enclosing a demounted bicycle frame in an upside-down position. 
     In one embodiment of a first connector element  531  comprises a strap  541  fixedly or detachably connected to a first tubular element  60  and partly surrounding the first tubular element  60 . Two outer end portions of the strap  541  extend in parallel and are connected to a short tubular sleeve element  540  by means of a screw or similar such that a hinged connection is provided. The short tubular sleeve element  54  can thus be pivoted or folded down to extend in parallel with the first tubular element  60  during storage when the frame structure is not in use. 
     The second connector element  532  may comprise a strap  542  with two free outer end portions partly surrounding a first tubular element  60 , and being fixed thereto by means of a screw, a bolt or shaft (not shown) crossing the first tubular element  60 , and e.g. a nut, or any other appropriate fastening means in any manner known per se, two free outer end portions thereof extending in parallel and being connected to the connection bar  53  by means of a screw (not shown), a shaft or similar such that a hinged connection is provided, such that the connection bar  53  can be pivoted around the axis formed by the screw and bolt, shaft or other appropriate connection means. The connection bar  53  can thus be pivoted or folded down to extend in parallel with the tubular element  60  for being stored when the frame structure is not in use, i.e. in a demounted state, and folded out to be substantially perpendicularly to the tubular element  60  at mounting. 
     For mounting of a frame section  51 , 52 , in an alternative, not shown embodiment, tubular elements of a smaller diameter D2 are introduced a slight distance into tubular elements  60  with a slightly larger diameter, and are blocked from being introduced therein more than a predetermined distance by means of first and second hinge connector elements  531 , 532 . 
     In advantageous embodiments a covering arrangement is connected to or associated with a cover frame structure  50  as referred to above, and the bicycle wheels  69 , 69  are held in openable pouches or pockets provided on the inner sides of said covering arrangement (see below). 
     It is an advantage that the frame structure can be extremely easily mounted/demounted, and fabricated, and that it is not space demanding in a demounted state. It comprises but two, three or four different types and /or dimensions and shapes of tubular elements  60 , 62 , 63 , and connection bars  53  which are connected or connectable to the tubular elements, along which they can be folded down, or which can be removed from tubular element connecting means for connection on two opposite sides. In alternative embodiments both first and the second connector elements  531 , 532  may comprise sleeve elements able to releasably receive a connection bar  53  there between. 
       FIG. 5A  is a schematic view of a leg  734 , according to one embodiment comprising straight tubular elements  60 , 60 , a bent tubular element  62 , a sleeve  66 , a first hinge connector element  531  and a second connector element  532  according one embodiment at an interconnection  555  between two straight tubular elements  60 , 60 , and an interconnection  554  between a straight tubular element  60  and a bent tubular element  62  at a first hinge connector element  531 . 
       FIG. 5B  is a view similar to that of  FIG. 5A  in cross-section. The position of a first tubular element  60  with respect to a second tubular elements  60 , here having the same cross-sectional dimensions, e.g. the same diameter, is in the shown embodiment secured by means of a slidably mounted sleeve  66  of a larger diameter than the tubular elements  60 , 60 . The position of the sleeve  66  can in turn can be secured by means of spring biased element  68  comprising a metal band spring with oppositely directed protruding pins  67  at the outer ends of the bent metal band or similar that can be actuated through openings  660 , in one of the tubular elements  60  (due to a blocking functionality provided by means of the second connector element  532 ), or in both tubular elements  60 , 60 , as also discussed above. Thus, if a force is applied on the pins  67 , the metal spring  68  will be compressed, the pins  67  introduced into the holes  660  in the tubular elements  60  and the sleeve  66  can be moved. At the other end, the movement of the sleeve  66  is, as referred to above, restricted by the second connector element  532  for a connecting bar  53  (not shown). Alternatively no sleeves are used but instead separate tubular element connecting means. 
       FIG. 5C  is an enlarged view of the area indicated A in  FIG. 5B  view showing the interconnection  554  more clearly, position blocking being provided by means of a blocking pin  535  or similar of the first hinge connector element  531 . 
       FIG. 5D  is an enlarged view of the area indicated B in  FIG. 5B  showing the interconnection  555  formed by the sleeve  66 , the spring biased element  68 , pins  67  etc. as discussed above at one end, and the hinge connector element  532  e.g. with a blocking pin  536  or similar at the other end. 
       FIG. 6  is a schematic illustration of a protective arrangement  80  adapted in shape to the frame of a partly demounted bicycle frame, and comprising a downwards open flexible shell or similar forming a protective bag that simply can be pulled over the partly demounted bicycle frame when disposed upside down and connected to the saddle holder and the handlebar adapter connecting arrangement and before, or after, placing it in an optional covering arrangement  90 , see  FIG. 7 . It should be clear that although lower profile elements  41 , 42  and bottom support plate  45  are illustrated in  FIG. 6 , they may alternatively be connected after arranging in a covering arrangement (see  FIG. 7 ). Still further, these elements are not necessarily mounted externally, but may also be connected to the support frame structure or form parts thereof. The protective bag  80  is preferably made of foamed polypropylene or polyethylene or another foamed material, felt, fabric or non-woven fabric. It serves the purpose of protecting the bicycle frame. It also serves the purpose of protecting the covering arrangement (see  FIG. 7 ) against dirt on the bicycle frame. It has the advantage that it is cheap and easy to fabricate and mount. It is also easily replaceable. 
       FIG. 7  is a view in perspective of a bicycle transportation support and packaging structure with an exemplary covering arrangement  90 . The covering arrangement  90  preferably is made of a fabric, e.g. of coated polyester, which in the shown embodiment is not padded or reinforced, since a protection of the bicycle frame (and wheels) is provided by means of the protective bag  80  discussed above, and wheel protecting elements (see  FIG. 8 ). In alternative embodiments the covering arrangement  90  may be partly or entirely padded or reinforced. It may for example comprise a laminated fabric with foam. It comprises a front portion  91  and a rear portion (not shown), an edge portion  92  extending to surround the first and second cover frame sections, around the corner elements, and to the location where the lower profile elements  41 , 42  are to be connected by means of screws  411 , 421  or similar in a mounted state of the structure  100 , and a bottom portion  95 . As can be seen also the bottom support plate  45  is connected externally of the covering arrangement  90  by means of screws, bolts  451  or similar. 
     The covering arrangement  90  is thus shaped to, in a mounted state, be arranged so as to surround the cover frame structure  50 , and is preferably provided with channels, straps or similar into which the tubular elements  60 , 62 , 63 , separately or partly mounted e.g. to form legs  731 , 732 , 733 , 734  (see  FIG. 4 ), are to be introduced before, or upon, mounting of the cover frame structure  50 . The respective channels have such lengths that the tubular elements easily can be introduced before being interconnected. In one embodiment there is at least a separate channel which is curved for each corner element  62 , 63 . There are also at least one separate straight channel for each upper portion, and at least one separate straight channel for each of the side portions. The corner channels are adapted to the shape of the corner elements  62 , 63  (see e.g.  FIG. 1 ). The channels may be formed by the fabric along its outer edges being folded back and sewn onto itself such that a number of channels of a desired width and at a desired distance from each other are formed, allowing the tubular elements to be easily inserted/removed, or as an alternative to channels, straps, bands or similar may be used. If only bands or straps or similar are used, there is no need for an adaptation to the shape of the tubular elements. 
     The edge portion  92  is, preferably in the middle, provided with a zip fastener  96  extending from one end to the other, i.e. at opposite ends adjacent to the bottom portion  95 , or preferably into the bottom portion, in a mounted state. 
     The inner sides of the front and rear side cover portions are not shown, but are preferably provided with closable pouches or pockets  97  (See  FIG. 8 ) adapted for reception of the bicycle wheels  89 . The pockets  97  are preferably closable by means of a respective zip fastener  98 . Flat, circular protecting elements (not shown) e.g. made of foamed polypropylene or similar, cf. the materials discussed with reference to the protective arrangement  80 , of a diameter similar to that of a wheel are preferably introduced between the wheels  89  and the side cover portions. 
     Adjacent to the upper edges of the front and rear cover portions, handle attachment means  77  for releasably receiving a handle  78  (see also  FIG. 8 ) are provided. 
       FIG. 8  is a view showing the bicycle support and packaging structure  100  in a mounted, closed state, also with part of the front cover portion  94  removed in order to illustrate a pocket or pouch  97  for a bicycle wheel  89  provided at the inner side of said front cover portion  94 . Similar elements bear the same reference numbers as in  FIG. 7 . The pocket  97  is provided with a zip fastener  98  to allow easy insertion and removal of a bicycle wheel  89 , and securing the wheel  89  in place during transportation. In an advantageous embodiment protecting elements may be inserted outside the wheel, in the pockets  97 . Alternatively a reinforcing section may be provided in the side cover portion  94 , or the wheels  89  may be inserted into protective bags before insertion into the pockets  97 , or the covering arrangement is protective in itself, e.g. padded or stiff. Many variations are possible. The rear cover portion is similar to the front cover portion  94  provided with a pocket. 
     One or more handles  78 , which are removably attached to handle attachment means  77 , and connected to the front and rear cover portions  94  may be provided. A handle may alternatively be fixedly attached to one of the side cover portions, or even to the edge portion allowing pulling/pushing the transportation support and packaging structure  100  on the wheels  69 , 69 , and allowing the zip fastener to be fully opened. 
     As discussed above, e.g. with reference to  FIG. 2A , alternatively, or additionally, on or both of the lower profile elements  41 A, 42 A are adapted to also provide the functionality of a handle. Of course additional handles may be provided on the outer side cover portions of the structure. It should be clear that the invention is not limited to the specifically illustrated embodiments, but that it can be varied in a number of ways within the scope of the appended claims. Particularly it is not limited to any particular numbers, sizes and shapes of tubular elements or elements forming the cover frame structure. It is also not limited to the use of any particular covering arrangement, or protective bag. Still further the support or carrier structure may comprise a bottom plate or a tray, or a fixed frame structure, with handlebar connecting arrangement and a saddle holder disposed adjustably with respect to one another to allow for transportation of frames of different sizes and dimensions. 
     In an alternative embodiment the saddle holder connector distance element may e.g. comprise or be provided by means of a saddle adapter comprises a saddle post connecting means e.g. comprising two clamping rods or bars disposed in parallel and adapted for being introduced into saddle post guide rails (normally used for reception of a saddle) which often are standardized such that the saddle adapter can be used for a large number of bicycles without requiring replacement of e.g. the rods. If the saddle comprises an I-beam, saddle post connecting means would have to be adapted accordingly, such saddle post connecting means e.g. being connected to a connector element which comprises two through holes through which two parallel saddle adapter distance element connecting means can be adjustably disposed, and which in some cases may be detachable. The saddle adapter thus comprises the distance element which is either fixedly or releasably connected to corresponding outer ends of respective saddle adapter distance element connecting means. The distance element then extend substantially perpendicularly to, and protrude on both sides of, the longitudinal extension of saddle adapter distance element connecting means. 
     It should also be clear that the tubular elements of the cover frame structure alternatively e.g. may comprise telescopic elements or any other type of elements, of any number, from one to more depending on transportation and storing requirements, securable in certain positions in any appropriate manner. 
     The longitudinal elements of the support frame structure may comprise telescopic elements securable in certain positions with respect to one another, or one, or two or more demountable tubular elements of any cross-sectional shape. 
     The invention is also not limited to the use of any particular materials of a covering arrangement. Further, it is also intended to cover structures wherein the covering arrangement does not comprise any pockets, but wherein the wheels are transported or kept separately, or pockets may be disposed at the outer sides of the covering arrangement. 
     In advantageous embodiments the tubular elements of the cover frame structure are made of a plastic material, or in some embodiments of carbon fiber, steel or aluminium. 
     In advantageous embodiments the longitudinal elements of the support frame structure are made of steel or aluminium or of carbon fiber, or in some embodiments even of plastic. 
     The saddle holder and handlebar connecting arrangement, or at least the connector distance elements, are preferably made of aluminium, or any metal or metal alloy or an appropriate plastic material having similar properties, but may alternatively be made of carbon fiber or steel. Aluminium has the advantage of having a low weight, providing a particularly light-weight structure, which also is cheap. 
     In an advantageous embodiment of the invention the bicycle (transportation) support and packaging structure  100  also comprises a flexible bag, e.g. having the dimensions of approximately, but not limitedly, 30 cm×30 cm×40 cm, for transportation of all the other elements forming part of the bicycle transportation support and packaging structure  100  as described above in a demounted state, which is extremely advantageous from a storing and transportation point of view. 
     Still another advantage is that the structure is easy and cheap to fabricate, and that for example only a few dimensions/shapes of tubular elements are needed for the frame structure, and that it can be used for different bicycle frames without substantial modification, particularly facilitated through connection of the handlebar adapter connecting arrangement to the head tube of the front fork tube normally is standardized, and through the saddle holder which removes the need of removing the saddle which is extremely advantageous.
