Patent number: 11918848Abstract: Proposed is a slat having a truss structure, the slat including: a main body provided with a stepping part which receives the load of a user, and a coupling part which is formed on both sides of the stepping part and may be fixed to a track belt; and a truss part connected to the stepping part so as to distribute the load applied to the main body. Thus, since the load applied to the stepping part is distributed by a diagonal member part and a chord member part of the truss part, the bending of the main body caused by the load is minimized, and thus damage to the main body caused by the load may be prevented.Type: GrantFiled: June 8, 2020Date of Patent: March 5, 2024Inventors: Bo Young Chang, Min Wung Kim

Patent number: 8037721Abstract: In a foreign materials filtering apparatus and a washing machine having the same, a filter unit is not exposed to inside of a washing tub thus not to directly come in contact with laundry, thereby preventing the filter unit and laundry from being damaged and enhancing the entire appearance. Also, the foreign materials filtering apparatus is modularized to facilitate a detachable mounting, thereby enhancing the user's convenience. Additionally, the amount of washing water passing through the foreign materials filtering apparatus is increased by controlling a flowing direction of washing water. Furthermore, foreign materials of washing water are prevented from being introduced into a gap between a washing water circulating duct and a filter unit, thereby enhancing a washing effect.Type: GrantFiled: March 4, 2008Date of Patent: October 18, 2011Assignee: LG Electronics Inc.Inventors: Sang-Hee Yoo, Jong-Deuk Bae, Bo-Young Chang, Young-Bae Park, Ji-Maeng Kim, Soo-Jin Jung, Ae-Na Jo

Patent number: 8020413Abstract: In a foreign materials filtering apparatus and a washing machine having the same, owing to a detachable mounting structure between a handle and a front filter and between a rear filter and the front filter, foreign materials collected in a foreign materials filtering space can be easily cleaned. Accordingly, can be solved the conventional problem that a net filter has to be kept inside out at the time of a cleaning process, resulting in causing a user's hands to become dirty. Also, can be solved the conventional problem that there is a difficulty in removing foreign materials from the net filter due to a fibrous characteristic of the net filter.Type: GrantFiled: March 4, 2008Date of Patent: September 20, 2011Assignee: LG Electronics Inc.Inventors: Sang-Hee Yoo, Jong-Deuk Bae, Bo-Young Chang, Young-Bae Park, Ji-Maeng Kim, Soo-Jin Jung, Ae-Na Jo
