Description

【０００１】
【発明の属する技術分野】
本発明は、自動車用窓等に用いるガラス板に孔（凹所及び貫通孔を含む）を複数形成するガラス板の孔開け方法及びその装置に関する。
【０００２】
【従来の技術】
この種のガラス板の孔開け装置は、ガラス板に孔開けすることのできる領域を広く確保するためにガラス板の略中心部における狭い領域をテーブルによって支持し、支持されたガラス板の孔開けすべき所定部位の近傍をクランプ手段（挟持手段）により局部的に拘束保持（挟持）し、その後、孔開け工具（穿設工具）により当該ガラス板の所定部位に孔開けを行うようになっている。
【０００３】
【特許文献１】
特開平２−８８１０９号公報
【０００４】
しかしながら、斯かるガラス板の孔開け装置では、テーブルによりガラス板の狭い領域を支持するために、孔開け工具による孔開けの際に生じ得るガラス板の撓みを抑えるべく上述のようなクランプ手段を別個に具備する必要があることから、ガラス板の孔開け装置自体の構成が複雑となってしまい、而して、ガラス板の孔開け装置の製造コストを低く抑えることが困難であると共に当該装置の定期的な整備作業も煩雑となり得る。
【０００５】
また、斯かるガラス板の孔開け装置では、孔開け工具によりガラス板に孔開けする前にクランプ手段によるガラス板の拘束保持を行うために、ガラス板の孔開け工程が増えてしまい、従って、ガラス板の孔開け工程を減らしてガラス板の孔開けを短時間で行うことが困難である。
【０００６】
【発明が解決しようとする課題】
本発明は、前記諸点に鑑みてなされたものであり、その目的とするところは、ガラス板に撓みを生じさせずに精確に孔開けすることができ、簡単な構成にして製造コストを低く抑えることができると共に整備作業をも容易に行い得、ガラス板の孔開けを短時間で行うことのできるガラス板の孔開け方法及びその装置を提供することにある。
