PROBLEM TO BE SOLVED: To provide a bed apparatus capable of smoothly tilting an upper frame, while preventing backlash in the left/right and front/back directions when tilting the upper frame of the bed apparatus with a simple configuration.SOLUTION: The bed apparatus includes: lifting/lowering mechanisms in the lower part of the upper frame at a head side and a foot side respectively, where the head-side and foot-side lifting/lowering mechanisms are connected to each other, and a first lifting/lowering mechanism of the head-side and foot-side lifting/lowering mechanisms is connected to the upper frame by hinges a transmission member that transmits the lifting/lowering motion of a second lifting/lowering mechanism of the head-side and foot-side lifting/lowering mechanisms and a guide mechanism that, when lifting/lowering, regulates left/right motion of the upper frame with respect to the lifting/lowering mechanisms and guides the front/back motion in a prescribed manner.COPYRIGHT: (C)2015,JPO&INPIT【課題】 ベッド装置の上部フレームを傾ける際の左右及び前後へのガタつきを簡単な構成で防止してスムーズに上部フレームを傾動させることができるベッド装置を提供する。【解決手段】 上部フレームの下方には、頭側及び足側それぞれに昇降機構が設けられ、前記頭側及び足側それぞれの昇降機構同士が連結され、頭側及び足側のうちの第1の昇降機構が該上部フレームにヒンジ結合され、頭側及び足側のうちの第2の昇降機構の昇降動を伝える伝達部材と、昇降時に昇降機構に対しての上部フレームの左右動を規制しかつ前後動を所定に誘導するガイド機構とを設けたことを特徴とするベッド装置。【選択図】図3
