Description
図1および図2は、第一の実施形態に係る運動案内装置の一形態を示す図であり、特に、図1は、第一の実施形態に係る運動案内装置の概略構造を説明するための斜視分断図であり、図2は、第一の実施形態に係る運動案内装置の縦断面図である。
次に、本発明が取り得る別の形態例として、図11を用いることで第二の実施形態に係る運動案内装置200についての説明を行う。ここで、図11は、第二の実施形態に係る運動案内装置の要部を示す部分斜視図であり、図中の分図(a)には段落ち加工部に対する取付部の取り付け前の状態が示されており、分図(b)には段落ち加工部に対する取付部の取り付け後の状態が示されている。なお、図11において、上述した第一の実施形態の場合と同一又は類似する部材については、同一符号を付すことで説明を省略した。
以上説明した第一および第二の実施形態に係る運動案内装置10,200では、FRPで構成された軌道本体部31の端部に段落ち加工部71を形成しておき、この段落ち加工部71が形成された箇所に嵌り込むように、金属材料から成る取付部75を接合するものであった。しかしながら、本発明の適用範囲は、軌道本体部31の端部に対してのみ適用されるものではなく、例えば、軌道レール11の縦断面略U字形の底面側であって、その長手方向に適宜間隔をおいて複数形成されるボルト取付孔に対しても適用することができる。その具体例を、図12および図13を用いて説明する。ここで、図12は、第三の実施形態に係る運動案内装置を説明するための図であり、図中の分図(a)は運動案内装置の全体構成を示す斜視図であり、分図(b)はボルト取付孔の周辺を示す要部縦断面図であり、分図(c)は軌道レールの構成部材であるFRPの特性を説明するための模式図である。また、図13は、第三の実施形態の具体的な実施事例を示す図である。
上述した第三の実施形態では、軌道レール311の縦断面略U字形の底面側であって、その長手方向に適宜間隔をおいて複数形成されるボルト取付孔311bに対して、本発明を適用した場合の形態例を示した。この第三の実施形態については、さらに別の変形形態を適用することが可能である。そこで、図15および図16を用いることで、第四の実施形態に係る運動案内装置を説明する。ここで、図15は、第四の実施形態に係る運動案内装置に用いられる軌道レールを説明するための図であり、図中の分図(a)は組み立て前の軌道レールの底面側を示す分解斜視図であり、分図(b)は組み立て後の軌道レールの底面側を示す斜視図であり、分図(c)は組み立て後の軌道レールの上面側を示す斜視図である。また、図16は、図15中の分図(c)におけるA−A断面を示す状態図に対して、締結手段であるボルトを設置した場合を示した図である。
