The present invention relates to a joining structure for a frame of a bicycle. The present invention provides a joining structure for a frame of a bicycle having a main frame including a horizontal tube, a vertical tube, an inclined tube, a pair of seat stay tubes and a pair of chain stay tubes. One side of the horizontal tube and one side of the inclined tube are joined to a head tube cell. The other side of the horizontal tube, one side of the vertical tube and one side each of the pair of seat stay tubes are joined to a seat tube cell. The other side of the vertical tube, the other side of the inclined tube and one side each of the pair of chain stay tubes are joined to a bottom tube cell. The other side of the pair of seat stay tubes and the other side of the pair of chain stay tubes are joined to a drop-out tube cell. The abovementioned tubes and cells are joined by a joining member through a press-fitting process. The joining member is a hollow cylinder having a stopper protrusion formed at the center of an outer surface thereof. A plurality of slits is formed into a predetermined length inwardly from both ends of the joining member, respectively, extending from the center of the stopper protrusion. Each of the slits has an end with a through-hole. A plurality of sawteeth protrusions are formed inwardly from the both ends of the joining member, respectively. The sawteeth protrusions are formed at the surfaces between the stopper protrusion and the slits with through-holes, respectively. The present invention eliminates the necessity of a welding process to prevent bicycle accidents caused by faulty welding. The elimination of a welding process results in an economical advantage in a manufacturing process, and eliminates the need for expensive welding equipment. The present invention finishes a painting process for joining members such that the joining members have a variety of patterns prior to an assembly process, thus achieving an aesthetic enhancement. The present invention utilizes not only the same type of metals but also metals of different types, synthetic resins or a variety of natural materials, thus obtaining a variety of designs and an aesthetic enhancement. The present invention enables the assembly of the bicycle frame and the production of the bicycle having an independent model design.

The present invention is a well-being friendly door that is clearly distinguished from conventional doors which block off the front from the rear, and meets the needs for a healthy and happy life. The present door comprises external frame (10) configured with a frame having four angles including top, bottom, left and right, said external frame (10) inserted into base frame (10-1) such that one side is connected with door hinge (10-2), wherein vertical bar (10-5) is installed on the front and rear; metal plate (10-4) mounted with a door handle and a door lock formed on one side of said vertical bar (10-5) and the other side is cut open to form a space to the front of which is mounted safety insect net (10-7) or a plate material having a plurality of small punched holes therethrough, and to the rear of which is mounted folding door (R) that can be opened and closed; to provide insect-free ventilation, energy reduction, safety and entryway lighting.
The present invention relates to a vibration generator which comprises a unidirectional output device including a planetary gear train and a unidirectional clutch bearing, wherein a crank with an elastic body is attached to each front end of two separated drive shafts; vibration energy from a fast and powerful object is rotatably output as a reciprocating motion of the crank only in one direction irrespective of the rotation direction of an input; and a torque being rotatably output only in one direction towards the unidirectional output device serves to increase the RPM via a high speed gear and then to rotate a rotator of the generator continuously such that electric power can be obtained. Particularly, a vibration generator of the present invention is a very economical and effective device in that the crank with an elastic body attached thereto is fixed to drive shafts on both sides and receives vibration energy from an object that vibrates fast and powerfully, and that the vibration energy rotates a ring gear of the unidirectional output device comprising a planetary gear train and a unidirectional clutch and featuring separate drive shafts, as well as a rotator of the generator continuously, thereby enabling electricity generation.
