Definitions

  • the invention relates to a bicycle frame with storage compartment, wherein the frame has an approximately vertical oblique head tube at the front, an approximately vertical oblique rear frame tube at the rear that accommodates a seatpost and at the lower end of which it has a bore to accommodate the axle of a chain wheel or a belt drive wheel, and near the bore of the rear frame tube it attaches to a lower frame tube that runs to the head tube obliquely and upwardly, and the parts of the frame tubes altogether surround and define a central hollow space in which the storage compartment can be placed.
  • Bicycle transport in cities is getting increasingly popular nowadays, as more and more people shift to travel by bicycle at least partly due to crowded public roads and traffic jams.
  • One of the barriers to this process is the fact that the possibility of transporting luggage on a bicycle - compared to transporting it by car - is greatly limited in terms of both the size of the luggage and the method by which it is carried on the bicycle and/or on the cyclist.
  • Undoubtedly, the awkwardness of transporting luggage has a massive impact on the daily choices of passengers concerning their preferred means of transport, which may account for the large number of people who continue to travel by car or public transport instead.
  • Smaller objects can only be transported in a bag, because these objects would otherwise fall out of the structure.
  • the size of the storage space is also limited, and the solution does not exceed the standard dimensions of a classic frame in the symmetry plane of the vehicle.
  • the DE 19723886 (CI) and DE19723887 (CI) solutions offer a storage box from a textile-like material that is placed into the first triangle. These are storage elements placed into the first triangle of a male frame, attached to the tubes surrounding the triangle. Noticeably, a very similar solution has been used since the second world war on bicycles of the German and Swiss army (under MO- 05, MO-93, and then MO- 12 registration numbers), where (most similarly) a bag has been placed into the first triangle of the bicycle that follows the shape of the frame and mounted to the frame tubes. This is another special solution, where the bag can be opened at the side.
  • the primary object of the invention is to create a bicycle with a frame that can be complemented with a centrally-positioned storage compartment that prevents the listed disadvantages, while being aesthetic and without encumbering pedalling of the cyclist.
  • the secondary object of the invention is to develop carbon fibre reinforced plastic frames in such a manner that facilitates the creation of the storage compartment along with creating the frame, both in the same technological step.
  • the invention is based on the recognition that a novel combined approach and possibilities in using the light and stiff carbon fibre or other composite materials facilitates the creation of a storage compartment in the central zone of the bicycle, in place of the first triangle between the head tube and the seat tube, that is accessible from above and that possesses the aforementioned advantageous attributes in an ideal combination.
  • the frame has an approximately vertical oblique head tube at the front and an approximately vertical oblique rear frame tube at the rear that accommodates a seatpost.
  • the rear frame tube At the lower end of the rear frame tube here is a bore to accommodate the axle of a chain wheel or a belt drive wheel, and the rear frame tube - near the aforementioned bore - attaches to a lower frame tube that runs to the head tube obliquely and upwardly, and the parts of the frame tubes altogether surround and define a central hollow space in which the storage compartment can be placed
  • the lower frame tube has a bottom part that runs towards the front in an approximately horizontal path in a predetermined length, and a curved frame section runs obliquely to the headtube from the front end of the said bottom part section
  • the storage compartment made of reinforced carbon fibre or other composite sheet, is a unit encompassing a closed space that can only be opened and accessed from the top, and said storage compartment has
  • the upper opening of the storage compartment is closed by a tilting door. Strength of the storage compartment is enhanced if the upper opening is bordered by thickened and reinforced upper edges of the side walls.
  • the luggage space can be enlarged if the bottom line of the approximately horizontal section of the bottom part is level with or lower than the horizontal lower tangent of the chain wheel or belt drive wheel.
  • the manufacturing process becomes much simpler if the storage compartment, excluding the door that closes the upper opening, is a shell structure made as one piece.
  • the frame is a uniform shell structure made with carbon fibre technology or made of another composite material, where the frame has an approximately vertical oblique part at the front to accommodate a head tube, a part to accommodate a seatpost at the rear, an approximately vertical oblique rear frame edge at the lower end of which is a bore to accommodate the axle of a chain wheel or a belt drive wheel, and the storage compartment, according to the invention, is a hollow space formed in the centre of the frame structure, which is bordered by load- bearing structural elements of the frame at the front, bottom and rear, and two slightly bowed, approximately vertical side walls that follow the frame curvatures, and there is an opening at the top of the storage compartment with a door through which luggage is placed or removed.
  • the storage compartment is aesthetic and its rainproof internal space facilitates careful transportation of luggage.
  • the storage compartment can be manufactured together with the frame in the same technological step, which decreases manufacturing costs and facilitates making a professional and beautiful product.

  • Figure 2. is a front view of an integrated female bicycle frame with central storage compartment, lowered bottom part and storage compartment door;
  • Figure 3 is a front view of an integrated bicycle Y-frame with central storage compartment and lowered bottom part;

  • the upper door 12 of the storage compartment can be opened upwards by turning around its axis of rotation 14. It can be recognized on the illustration that the bicycle frame has no upper frame tube, because the storage compartment takes its place.
  • this bicycle frame is designed between the head tube 4 and the rear approximately vertical frame tube in such a way that from the edge at the axis of rotation 18 the frame continues towards the front approximately horizontally or with a little elevation, and at the bottom, it bends up from a bottom part to the head tube 4.
  • this design such a large, slightly trapezoid space is created in the frame for the storage compartment where the necessary luggage, such as a briefcase, can easily be placed.
  • the side walls 2 form a hollow trough with the frame, or more precisely, the trough sits on the frame tube and the side walls 2 then bow outwards to provide appropriate internal space for accommodating the luggage.
  • frame parts can be made of any kind of load bearing profile instead of tubes, such as U or V profile open sections, carbon fibre reinforced spatial profile or from various parts.
  • the function of these elements is to bear the load as a whole system and to establish a strong connection between the front and the rear wheels.
  • Figure 2 illustrates the embodiment of an integrated female bicycle frame with central storage compartment, and visualizes the side walls 2 of the storage compartment surrounded by the lower edge of a chain wheel 18, the central section of a seat tube 7, the head tube 4, and the reinforced upper side wall edges 3, the side walls of which 2 attach to a lowered bottom part 17 that is a continuation of a lowered chainstay 1 1, to the head tube 4 and to the seat tube 5.
  • the shape of the storage compartment also orientates to the chain guard 10 protecting the chain wheel 9, and the upper door 13 of the storage compartment 12 is accessible by means of a zip fastener.
  • the bottom part 17 of the frame includes a horizontal section from the rear edge towards the front, and the curve of the frame only bends up towards the head tube 4 from the front edge of this horizontal section.
  • the storage compartment is not horizontal but has an oblique upper part inclining backwards so as to provide maximal convenience to female cyclists, too.
  • Figure 3 illustrates the embodiment of a bicycle Y-frame with integrated central storage compartment.
  • the storage compartment is bordered by the lower edge of the chain wheel 18 at the 5 bottom, by the upper end of the seat tube 6 at the rear and at the top, and the central part of the bottom part 15 at the front.
  • the two side walls 2 meet in such a manner that a concave groove is established between them that follow the curvatures of the side walls, the concaveness of which fits to the bent shape of the frame tube.
  • the reinforced side wall edges 3 establish the edge of the internal space and provide appropriate strength and stability.
  • the upper door 12 of the storage compartment can be opened and closed by turning it around the horizontally oriented axis of rotation 14 at the front.

  • the solution comprising the core of the invention also offers the above advantages in case of child bicycles, although in such cases, due to lower speed and lighter luggage items, one of the main functions of the storage compartment might be to store knee and elbow protectors and smaller toys. It is reasonable to store the protectors together with the bicycle because equipment stored separately is often left at home.
  • the storage compartment according to the invention replaces a traditional front or rear luggage rack or basket, then aerodynamic features of the vehicle will be improved.
  • headwind in case of a city bicycle, the additional drag incurred by the storage compartment solution is negligible, especially in the case of it replacing a front basket that does itself significantly increase the drag coefficient.
  • the body of the cyclist on the bicycle is perpendicular to the direction of travel and the potential increase in drag should be taken into account with that in mind, as the storage compartment is arranged in parallel with the plane of the direction of travel and thus the drag increase caused by it is less in the direction of travel.
