The reason for and the necessity of the two parallel independent claims of the present invention for riding a bicycle.

The invention discloses a bicycle for riding and running, belongs to a general inventive concept and a bicycle with two parallel technical schemes, and is a novel bicycle which combines the bicycle movement belonging to the technical field of bicycles and the running movement belonging to the technical field of running movement. Is a novel riding bicycle which has double functions of riding and running simultaneously on one bicycle. In order to realize the general inventive concept of the present invention, the present invention includes the following two indispensable and interrelated technical solutions:

the first solution is also the first independent claim of the invention for a bicycle for running: the rear shaft 207 is connected with a lower support bearing 307, the lower support bearing 307 is connected with the rear end of the lower support 302, the lower support 302 extends upwards for a section, bends to turn to the front of the bicycle and extends for a section to be connected with the rear end of a lower support middle section circle support 311, the front end of the lower support middle section circle support 311 is connected with the lower support 302, and the lower support 302 is connected with the head pipe 202.

The first independent claim of the bicycle for running of the invention and the appended claims of items 2, 3, 4 and 5, which are produced in accordance with the first independent claim, form the key points for realizing the invention: a stent system 300. The frame system 300 is an essential bicycle riding key system for the creative dual functions of riding and running on a bicycle.

According to two of [0017] and [0018 ]: the upper circle support 301, the lower support 302, the vertical support 303, the support sling ring 305, the lower support bearing 307, the lower support middle section circle support 311, the sling 308, the sling saddle 309 and the sling belt 310 jointly form the support system 300. The bracket system 300 is a main support frame of the bicycle structure for riding and running, and is also the only support frame for connecting the front wheel 204 and the rear wheel 205 of the bicycle for riding and running; and is the point of application of the strap 308 of the present invention; is also the acting point of the riding and running dual-purpose sling saddle 309; the sling 308, the sling saddle 309 and the sling waistband 310 bear most of the weight of the human body under the combined action of the upper circle support 301, the lower support 302 and the lower support middle circle support 311, so that the legs and the feet of a runner do not bear the weight of the whole body any more, and the runner can run more easily. In view of the above, the rack system 300 is an indispensable independent claim of the present invention.

The second solution is also the second independent claim of the invention for a bicycle for running: the rear shaft 207 is connected with a lower bracket bearing 307, the lower bracket bearing 307 is connected with a lower bracket 302, the lower bracket 302 is connected with a transmission system bracket 410, the transmission system bracket 410 is connected with a transmission system underframe 408, the rear section of the transmission system underframe 408 is provided with a transmission system underframe shaft hole 409, the transmission system underframe shaft hole 409 is connected with the rear shaft 207, and the other end of the transmission system underframe 408 is connected with a middle shaft outer ring 407; the bottom bracket outer ring 407 is connected with a bottom bracket 401, and the bottom bracket 401 is connected with the bicycle transmission system 400.

The middle shaft 401, the crank 402, the pedal 403, the chain wheel 404, the chain 405, the flywheel 406, the middle shaft outer ring 407, the transmission system chassis 408, the transmission system chassis shaft hole 409 and the transmission system bracket 410 jointly form the transmission system 400.

According to item [0020], the transmission system 400 adds the innovative invention scheme of the invention on the basis of the original common bicycle transmission system: the innovative transmission system 400 is a detachable or rotatable transmission system 400, when the transmission system 400 of the present invention is rotated to the vertical position, the front wheel 204 and the rear wheel 205 are in a completely free state, the spatial distance between the two wheels has reached the length space required for the runner to run with the very long leg of a 2 m high athlete, and at this time, the state of riding the running bicycle has been changed from the conventional riding function to the running function.

According to [0020] and [0021] 2: the technical solution of the transmission system 400, which is detachable and rotatable and displaceable, is the inventive technical solution of the present invention for the bicycle of the present invention, is a key specific technical feature for solving the problem of insufficient running space of the present invention for the bicycle of the present invention, and is an essential independent claim for realizing the bicycle of the present invention. A tripod or a lower girder of a common bicycle; the fixed transmission system of the common bicycle cannot realize the desire of running on the bicycle. The running bicycle only has the support system 300, but still uses the traditional transmission system fixed on the tripod and the lower girder, and can not run due to insufficient running space; a running bicycle has only the transmission system 400 but no mounting system 300 and no room for running. The drive train 400 and the frame system 300 of the running bicycle; the structural interconnection, the interaction of the accessories, the supplement and the lack of the invention are the parallel independent claims of the combined bicycle riding device.

The transmission system 400 of the two independent claims of the present invention as a whole and the frame system 300 as a whole present a number of essential interrelationships in the technical solution of the present invention of a bicycle, and the necessary interworking for the functioning of the bicycle, providing the essential special contribution to the functioning of the bicycle of the present invention, both for riding and running, as exemplified below.

The bracket system lower bracket bearing 307 is mounted on the hub of the rear axle 207 of the running bicycle.

The driveline chassis shaft hole 409 is mounted on the hub of the rear axle 207 of the running bicycle.

The driveline flywheel 406 is mounted on the hub of the rear axle 207 of the running bicycle.

The upper end of the drive system support 410 is movably connected to the support system lower support 302.

The lower end of the transmission system bracket 410 is movably connected to the transmission system chassis 408.

The function of the bracket system lower bracket bearing 307 is to firmly connect the rear axle 207; the rear axle 207 can rotate in the lower bracket bearing 307, so that the rear axle 207 can rotate with the transmission system 400 to reach a vertical position, the transmission system 400 can be displaced, and a running space required by a runner is vacated. Mounting a bearing on the lower bracket 302; the mounting of the lower bracket bearing 307 on the hub of the rear axle 207 is an original feature for use on bicycles.

The function of the transmission system bracket 410 is to connect the bracket system lower bracket 302 and the transmission system 400 to form a firm triangular connection, and to cancel the connection at any time, so as to allow the transmission system 400 to shift, thereby making the space between the front wheel 204 and the rear wheel 205 empty for running.
