    • The present invention relates to a method for molding rubber blocks by combining rubber chips and a urethane binder, and more specifically to a molding method for rubber blocks whereby it is possible to improve the processing time and the physical properties of the product by introducing high-temperature steam during molding. The present invention has advantageous effects in that the molding can take place in a short time without affecting the physical properties of the product even in situations involving heavy molded products, and in that there is no risk of ignition due to self-heating even if the finished products are kept stacked.
    • 本发明涉及一种通过将橡胶片和氨基甲酸酯粘合剂组合而成的橡胶块的成型方法,更具体地说涉及一种橡胶块的成型方法,通过引入高分子化合物,可以提高加工时间和物性, 成型时温度蒸汽。 本发明的优点在于,即使在重型成型品的情况下,成型也可以在短时间内进行而不会影响产品的物理性能,即使在自发热的情况下也不会发生点火的危险 成品堆放。

    • The present invention relates to a roller board, and more particularly, to a pedal-driven roller board that converts a reciprocating motion of pedals formed on the board into a rotational motion to drive a gear, so that a user can drive the board without kicking the ground. Furthermore, the pedal-driven roller board includes a derailleur, so that a user can conveniently control the speed of the pedal-driven roller board. Moreover, a user can develop and strengthen his/her muscles by pedaling the pedal-driven roller board. To this end, a pedal-driven roller board according to the present invention includes: a handle disposed at the front side of a board to steer a front wheel; a rear wheel at the rear side of the board; and two pedals formed on the top surface of the board to drive the rear wheel. Further, the pedal-driven roller board includes: a link having an end hinged to the bottom surface of a pedal; a driving gear formed on an end of a crankshaft connected through a shaft to the other end of the link to convert a reciprocating motion of the pedal into a rotational motion; a clutch gear engaged with the driving gear to rotate, and selectively connected to one of either a first speed gear or a second speed gear to rotate same; a first connecting gear and a second connecting gear, which rotatably engage with the first speed gear and the second speed gear, respectively, and are installed on an end of a connecting shaft; a transmission gear installed on both ends of the connecting shaft and rotated by torque transmitted through the connecting shaft from the first and second connecting gears; and a rotation gear engaging with the transmission gear to rotate, and connected to the rear wheel through a rotation shaft to transmit the torque from the transmission gear to the rear wheel.
    • 更具体地说,涉及一种踏板驱动辊板,其将形成在踏板上的踏板的往复运动转换为旋转运动以驱动齿轮,使得用户可以在不踢踏板的情况下驱动板 地面。 此外,踏板驱动辊板包括拨链器,使得用户可以方便地控制踏板驱动辊板的速度。 此外,用户可以通过踩踏踏板驱动的辊板来开发和加强他/她的肌肉。 为此,根据本发明的踏板驱动辊板包括:设置在板的前侧以控制前轮的手柄; 位于板后侧的后轮; 并且在板的顶表面上形成两个踏板以驱动后轮。 此外,踏板驱动辊板包括:具有铰链到踏板的底表面的端部的连杆; 驱动齿轮,其形成在通过轴连接到所述连杆的另一端的曲轴的端部上,以将踏板的往复运动转换成旋转运动; 离合器齿轮与所述驱动齿轮啮合以旋转,并且选择性地连接到第一速度齿轮或第二速度齿轮中的一个以使其旋转; 第一连接齿轮和第二连接齿轮,其分别与第一速度齿轮和第二速度齿轮可旋转地接合,并且安装在连接轴的端部上; 传动齿轮安装在连接轴的两端并通过连接轴从第一和第二连接齿轮传递的转矩转动; 以及与所述变速齿轮啮合的旋转齿轮旋转,并且通过旋转轴连接到所述后轮,以将所述转矩从所述变速齿轮传递到所述后轮。
