Description

可伸展且可盘卷片材
本发明涉及一种可伸展且可盘卷片材。
在其整个内容援引在此以作参考的WO-A-88/08620或WO-A-97/35706中揭示了可在盘卷状态与伸展状态之间双向成形的可伸展且可盘卷片材。图1中示出了此类片材1的一例的立体图。其中的片材1部分呈盘卷状态1a，而部分呈伸展状态1b。
根据本发明第一个方面，提供了一种可在盘卷状态与伸展状态之间双向成形的可伸展且可盘卷片材，在其至少一个表面上设有一个或多个弹性伸出物，以便当片材伸展成伸展状态时，该伸出物或各个伸出物呈现出自片材表面伸出的第一状态，而当片材滚动成盘卷状态时，该伸出物或各伸出物位于盘卷片材的各圈之间。
当片材处于伸展状态时，伸出物一般处于放松状态中，而当片材处于盘卷状态时，该伸出物将再次叠置在该表面上。该片材在提供用于环绕诸如管状物之类的另一个物体、用以例如隔热、隔声或电绝缘的壳套方面特别实用。
该表面可为内表面，并且当片材处于其伸展状态时，该伸出物或各个伸出物可自片材向内伸出。
该表面可为外表面，并且当片材处于其伸展状态时，该伸出物或各个伸出物可自片材向外伸出。
片材的内外表面上各设有至少一个伸出物，当片材处于其伸展状态时，内表面上的该伸出物或各个伸出物自片材向内伸出，并且外表面上的该伸出物或各个伸出物自片材向外伸出。
可设有第二可伸展且可盘卷片材，它具有附着在第一片材的该伸出物或至少一个伸出物的自由端上的表面，这样，该第二片材就能在盘卷状态时位于第一片材的各圈之间，而在伸展状态时籍由弹性伸出物而与第一片材的表面相隔离。
根据本发明第二个方面，提供了一种可在盘卷状态与伸展状态之间双向成形的可伸展片材，其内表面上设有附着在该可伸展片材上、或者构成该可伸展片材一部分的一个或多个弹性片状件，该弹性可使弹性片状件在片材伸展时呈现出自片材表面向内伸出的放松状态，而在片材滚动时可弯曲以位于盘卷材空隙内。
根据本发明第三个方面，提供了一种可在盘卷状态与伸展状态之间双向成形的可伸展片材，其外表面上设有附着在该可伸展片材上、或者构成该可伸展片材一部分的一个或多个弹性片状件，该弹性可使弹性片状件在片材伸展时呈现出自片材表面向外伸出的放松状态，而在片材滚动时可弯曲以位于盘卷材空隙内。
根据本发明第四个方面，提供了一种可在盘卷状态与伸展状态之间双向成形的可伸展片材，其两个表面上设有附着在该可伸展片材上、或者构成该可伸展片材一部分的一个或多个弹性片状件，该弹性可使弹性片状件在片材伸展时呈现出自片材表面向内、外伸出的放松状态，而在片材滚动时可弯曲以位于盘卷材空隙内。
根据本发明第五个方面，提供了一种可在盘卷状态与伸展状态之间双向成形的可伸展片材，其一个或两个表面上设有在该片材伸展时自表面延伸的一个或多个弹性片状件，弹性片状件的末端还附着在某个其它片材、电缆、光导纤维或其它装置上，弹性片状件在片材处于盘卷状态时位于盘卷材空隙内，而在伸展时则与片材表面相隔离，并籍由弹性自内或外表面延伸至上述表面。
以下结合附图，对本发明的实施例进行举例描述，在这些附图中：
图1是可在盘卷状态与伸展状态之间双向成形的可伸展且可盘卷片材的立体图，示出了该片材部分呈盘卷状态，部分呈伸展状态；
图2是本发明片材的第一例呈伸展状态时的端视图；
图3是图2所示片材呈盘卷状态时的局部剖视图；以及
图4是具有内外表皮(skin)的本发明片材的第二例的端视图。
请参阅图2，图中示出了本发明片材2的第一例的端视图。该片材2可在盘卷状态与伸展状态之间双向成形。图2示出了片材2处于其伸展状态2a。该片材2可根据WO-A-88/08620或WO-A-97/35706的原理来构制，或者可呈任何其它适当的形式。
在图示例中，片材2的内表面设有若干弹性伸出物2b。该伸出物2b可为沿着伸展片材2的整个长度、大致整个长度或者仅仅部分长度延伸的长片状件。例如，绕片材2的内表面一周设有彼此以120°间隔设置的三个这种类型的长伸出物2b。或者，伸出物2b可呈现短鳍状物组的形式，这些短鳍状物等角地设置在组内，并且若干个组沿着伸展片材2的整个长度、大致整个长度或者仅仅部分长度有间隔地重复设置。这些组可设置成：从末端看，不同的鳍状物2b彼此重叠，或者这些组或部分组可彼此偏置，以使鳍状物或者部分鳍状物2b沿着已伸展件2的长度有角度地隔开。
伸出物2b构成沿着片材2的长度的分隔物，以便例如当片材2环绕一管状物或其它伸展物体展开时，该伸出物2b可用于使片材2保持与管状物或其它物体的外表面相隔离的状态，由此该片材2可向该管状物或其它物体提供壳套。
当片材2从其伸展状态2a盘卷成其盘卷状态时，伸出物2b由于其弹性而弯曲，并由此变形而位于盘卷片材2的各圈3之中，如图3所示。类似地，当片材2从其盘卷状态滚动成其伸展状态2a时，伸出物2b向外弯曲成其伸展结构。
如果需要的话，可使伸出物2b位于形成在可伸展片材2的表面内的空腔中，这样当片材2处于其盘卷状态时，这些伸出物就不会增加片材的厚度。
伸出物2b可由与可伸展片材2的主体2a相同的材料制成，或者可由不同的材料制成。该伸出物2b可与可伸展片材2的主体2a一体成形，或者可籍由包括例如胶合或焊接在内的任何适当的手段附着到该主体上。较佳地，伸出物2b在它们与主体2a的接触点处对着一锐角，以便于片材2滚动成其盘卷状态。类似地，如图所示，伸出物2b较佳地以曲线离开主体2a的表面。
如图4所示，此类片材2可与WO-A-88/08620或WO-A-97/35706中所揭示的类型、或者任何其它适当类型的另一个可伸展片材结合在一起，以构成一种在伸展的同时形成一种具有双层表皮的片材4的片材，内外层或表皮4a,4b籍由弹性伸出物4c所隔离。该伸出物4c可固定在内外表皮4a,4b的其中之一或两者上、或者与其一体成形。
当从伸展状态滚动成盘卷状态时，两个表皮4a,4b一起滚动，弹性伸出物4c弯曲，以使这两个表皮在盘卷时能够靠拢。在这种情况下，提供内外表皮4a,4b的可伸展片材的拉伸及压缩挠性较佳地允许它们一起滚过所需的长度。以这种方式可增加任意数量的可伸展片材，以形成具有多层表皮的片材。
当在管状物或其它物体上展开成为壳套时、或者在上述具有多层表皮的装置的情况下，形成在可伸展片材2与其上设有或环绕着该可伸展片材的物体之间的一个或多个空腔、或者位于具有双层或多层表皮的片材4的表皮4a,4b之间的一个、部分或所有的空腔内可充满泡沫材料或其它材料，以便隔热、隔声和/或电绝缘、和/或抵抗冲击、和/或增加刚度。
需要的话，任何可伸展片材的边缘可籍由诸如焊接、拉链型连接等之类任何所需的手段暂时或永久性地进行连接或密封。当在具有多层表皮的装置4的表皮边缘上进行密封的情况下，形成一同心管，以便能进行分别的或双向的流动。
需要的话，可将能承受滚动的电缆、光导纤维、加热元件或任何其它装置装入到一个或多个可伸展片材内。
本发明将证明在设置用于保护管线或其它结构的绝缘或加热壳套方面特别实用，该壳套可在设置、或者对现有装备进行改装的同时展开在管线上，从而提供一保护性绝缘壳套，它还可安装用于监视管线状态的装置。
已具体参照图示例描述了本发明的一个实施例。然而，应当意识到的是，在本发明的范围内，还可对本发明进行多种改变及变形。例如，伸出物2b可设置在片材2的外表面上，以便向外伸出。伸出物2b可同时设置在片材的内外表面上，以便分别向内、外伸出。
