FIG. 4 is a perspective view illustrating the use of a truck for a skateboard in accordance with a first embodiment of the present invention, andFIG. 5 is a perspective view illustrating the truck for a skateboard in accordance with the first embodiment of the present invention. - Referring to
FIGS. 4 and 5 , thetruck 200 for a skateboard in accordance with the first embodiment of the present invention is installed on the lower surface of askateboard 100 and has ashaft 300 to whichwheels 310 are coupled. - The
wheels 310 are respectively coupled to each end of theshaft 300. Acoupling part 320 having a through-hole projects from one side of the middle portion of theshaft 300, and asupport part 330 projects from the other side of the middle portion of theshaft 300. - The
truck 200 to which theshaft 300 is mounted is formed of a plate-shaped member 210. Both ends of the plate-shaped member 210 are bent to face each other and define twocenter arms 230. Thecoupling part 320 is locked to onecenter arm 230 by aconnector 400, and theother center arm 230 has apocket 232 defined therein such that thesupport part 330 can be inserted into thepocket 232. Thepocket 232 is recessed sufficiently deeply therefor. Preferably, anelastomeric element 234 such as a urethane packing is coupled in thepocket 232 so that the free end of thesupport part 330 can be placed in theelastomeric element 234. Due to the presence of thesupport part 330 inserted into thepocket 232, thewheels 310 can be reliably held in place. When a skateboard turns, since thesupport part 330 finely pivots in thepocket 232 within a predetermined range, turning can be easily conducted. - In the
truck 200 for a skateboard according to the first embodiment of the present invention, in order to form thecenter arms 230 facing each other, both ends of the plate-shaped member 210 are bent twice such that the free ends of thecenter arms 230 are inclined downward to some extent. The twocenter arms 230 are separated from the base part of the plate-shaped member 210 which is directly locked to aboard 100. When forming thecenter arms 230 by bending, the angles of thecenter arms 230 can be variously changed as desired. Thus, since a person having ordinary knowledge in the art could readily conceive of such a change in angle, it is to be noted that simply changing the angle falls within the scope of the present invention. - The
coupling part 320 projectedly formed on one side of the middle portion of theshaft 300 has the through-hole, and onecenter arm 230 associated with thecoupling part 320 has ahole 236, so that theconnector 400 is passed through the through-hole and thehole 236 and locks thecoupling part 320 to thecenter arm 230. The connector may comprise a conventional bolt or an elastic member such as a urethane rubber. Preferably, theconnector 400 having the structure shown inFIGS. 6 and 7 is used. - That is to say, the
connector 400 is composed of a washer-integratedtype bolt 410, a shock-absorbingrubber 420 and anut 430. The washer-integratedtype bolt 410 has ahead part 412 which has a rounded upper surface, and is defined with awrench groove 414 on the center portion thereof. Afastening protrusion 416 is formed on the edge of the lower surface of thehead part 412. The shock-absorbingrubber 420 is placed on the upper and lower surfaces of thecoupling part 320 of theshaft 300 and surrounds the washer-integratedtype bolt 410. Thenut 430 is locked to the thread part of the washer-integratedtype bolt 410 which passes through onecenter arm 230. In the case of theconnector 400 according to the present invention, due to the fact that thewrench groove 414 is defined on the center portion of thehead part 412 of the washer-integratedtype bolt 410, it is possible to prevent thewrench groove 412 from being deformed due to friction. Also, since thefastening protrusion 416 is formed on the edge of the lower surface of thehead part 412 of the washer-integratedtype bolt 410, the shock-absorbingrubber 420 placed under thehead part 412 can be reliably held in place. - Next, the second embodiment of the present invention will be described.
FIG. 8 is a perspective view illustrating a truck for a skateboard in accordance with a second embodiment of the present invention. Referring toFIG. 8 , in thetruck 200 for a skateboard in accordance with the second embodiment of the present invention, thecenter arms 230, which are formed by bending both ends of a plate-shapedmember 210 to face each other, are integrally connected with each other. In other words, onecenter arm 230, having defined therein apocket 232, and theother center arm 230 having defined therein a hole, are integrally connected with each other. Due to this connection structure, the durability of thetruck 200 is improved, so that shocks transferred to theshaft 300 from thewheels 310 can be easily absorbed. - In the first and second embodiments, a plate-shaped reinforcing
piece 250 is placed under thecenter arm 230, such that it is possible for thetruck 200 to sustain an increased load. - Hereinbelow, the operation principle of the truck for a skateboard according to the present invention will be schematically explained. Unlike the conventional art, in the truck for a skateboard according to the present invention, both ends of the plate-shaped
member 210 having a springing characteristic are bent to define thecenter arms 230, and theshaft 300 having wheels coupled thereto is mounted to thecenter arms 230, whereby the shock absorption capability is improved and the jumping performance of the skateboard increases. - As described above, in the present invention, the
truck 200 is formed of the plate-shaped material having substantially the same elasticity as a leaf spring, and shocks are transmitted to theshaft 300 viawheels 310 which are brought into contact with the ground and roll thereon. Shocks transferred to theshaft 300 are effectively dispersed by thecenter arms 230, so that the shocks can be reliably mitigated. - As is apparent from the above description, in the truck for a skateboard according to the present invention, a shaft having wheels coupled thereto is mounted to center arms which are formed by bending a plate-shaped member, so that shock absorption capability is improved, and the jumping performance of the skateboard increases. The structure of the truck according to the present invention can be applied not only to a skateboard but also to various vehicles having wheels, thus contributing to the leisure industry.
