Frame for bicycle, connector and bicycle

#This application is the United States national phase of International Application No. PCT/NL2018/050279 filed Apr. 26, 2018, and claims priority to Dutch Patent Application Nos. 2018795 filed Apr. 26, 2017, and U.S. Pat. No. 2,020,780 filed Apr. 17, 2018, the disclosures of which are hereby incorporated by reference in their entirety.

#The present invention relates to a frame for a bicycle comprising a tube construction for providing fastening options for further parts of the vehicle, such as a steering pen, saddle pen and fastening means for a rear wheel. Furthermore, the present invention relates to a bicycle comprising the frame according to the present invention.

#It is a purpose of the present invention to provide novelty features relating to arranging of accessories or parts providing functional improvements to the bicycle in a frame. To this end, the present invention comprises a frame for a bicycle comprising a tube construction for providing fastening options for further parts of the vehicle, such as a steering pen, saddle pen and fastening means for a rear wheel, the tube construction comprising: a top tube, substantially extending in horizontal direction, a saddle tube, downwardly extending from a tube intersection with the top tube, from a fastening to the top tube at a substantially rear side thereof, a bottom tube, extending from a tube intersection with the saddle tube at substantially an underside of the saddle tube towards a connection at the top tube forwardly arranged relative to the fastening of the settled tube to the top tube, a head tube arranged at an angle by means of a tube intersection connected to the top tube, wherein the bottom tube extends to a predetermined distance above the upper side of the top tube, crossing the top tube at a tube intersection, and wherein the head tube is fastened to the bottom tube above the top tube.

#Further advantages, features and details of the present invention will be further elucidated on the basis of a description of one or more embodiments with reference to the accompanying figures. Similar yet not necessarily identical parts of different preferred embodiments are indicated with the same reference numerals.

#FIG. 1 relates to a schematic representation in side view of a first preferred embodiment according to the present invention.

#FIG. 2 relates to a schematic representation in side view of a further preferred embodiment according to the present invention.

#A first preferred embodiment according to the present invention relates to a frame one. This frame comprises a tube construction comprising a bottom tube 3, a top tube 2, a head tube 4 and a saddle tube 5, with also a bottom stay 6 and a top stay 7.

#The tubes are preferably welded together and are preferably aluminum tubes that are welded by means of aluminum welding. Hereby, tube intersections are formed where the tubes are crossing each other and welded together. The tube interconnection 10 is formed by the top tube with the saddle tube. The tube intersection 8 is formed by the top tube and the bottom tube. The tube intersection 9 is formed by the head tube with the top tube. The tube intersection 11 is formed by the saddle tube with the bottom tube. The tube intersection 12 is formed by the head tube with the bottom tube. The naming of the bottom tube is chosen based on the history of naming tubes of a substantially triangular frame. The present invention relates to a frame comprising an X shape wherein the X is formed by the bottom tube and the top tube. It is an important object of the X shape to have the bottom tube extend to above the top tube in order to provide a relatively long bottom tube for being able to accommodate a relatively long battery. Further goals and advantages are described in the above.

#To this end, at the location of the tube intersection, material of a tube is removed such that it does not extend in the inner space of the tube intersection. Because of this, for example a battery pack can be slid in the tube while this is not hindered by a crossing tube at the location of a tube intersection. Providing of such an hindered passage is not a requirement with all tube intersections. In many preferred embodiments, the bottom tube extends at the location of the tube intersection with the top tube. Because of this, a certain firmness of the bottom tube is maintained at the location of the tube intersection with the top tube.
