Abstract
Description
脚部1の底面とキャスタホイール2の接地面を一致させ、他の片側を持ち上げないときは4脚とも接地し、持ち上げたとき初めてキャスタホイール2が全重量を支えるようにすると、位置固定性がよくなり、対荷重性もキャスタなしの場合と等しくなる。(図1参照)
キャスタにはホイール2の軸4の方向が自由に変わる自在型のものと、軸方向固定型のものがある。そのいずれを選択するかは単方向移動を目的とするか、平面内移動を自在にすることを目的とするかによって変わる。
2 キャスタホイール
3 キャスタホルダー
4 キャスタ軸
5 取り付け用螺子釘
6 脚木部きりかぎ
7 床面
8 机、椅子等の脚を傾ける方向
Claims (2)
- 片側2脚の外側にキャスタをつけた四脚の机または椅子。
- キャスタを取り付けた脚部の外側下面を切り欠いて,他側を持ち上げたときキャスタホイールのみ接地するようにした、請求項1記載の机又は椅子。
