Description

码垛货盘的支梁
发明的技术领域
本发明涉及一种改进型支梁，用于主要由诸如波纹纸板或多层纸板等纸板材料制成的一类码垛货盘。这种改进型支梁具有高抗压强度和良好的侧向稳定性。
发明的背景技术
上述主要由诸如波纹纸板、多层纸板、或类似材料制成的这类码垛货盘及其制造方法，在Schmidtke的美国专利第4792325号、Quasnick的美国专利第4867074号、以及Smith的美国专利第5001991号之中作了举例说明，一般，这样一块码垛货盘包括一些细长的支梁和一些横撑件，从端头观看时它们各自具有一所需的外形。
正如这些专利中各自阐明的那样，从端头观看每一支梁具有大致为梯形的外形，这是通过折叠一块波纹纸板或多层纸板及类似材料而形成若干面板构成的，并由此确定了这种支梁对称的两个部分。其次，在每一支梁中，某些面板用粘接方式固定于其他一些面板上。
采用这种支梁的码垛货盘可以在市场上从印第安纳州克朗波因特市的盖特托板系统有限公司(Gate Pallet Systems，Inc.ofCrown Point，Indiana)买到，商标是PAYLOAD。通过改进用于这种码垛货盘中的支梁来改进码垛货盘所做的种种努力导致了本发明。
其他有关装置的码垛货盘在以下各专利中有些披露，它们是：Hermitage的美国专利第2728545号，Reberts等人的美国专利第3683822号，Melli的美国专利第4563377号，以及Atterby等人的美国专利第4802421号。
发明的概括
本发明提供一种改进型支梁，用于主要由诸如波纹纸板或多层纸板等纸板材料制成的一类码垛货盘。这种改进型码垛货盘是由一块单张的这种材料折叠而成的，以致至少具有11面面板。这些面板包括在大体铅直平面的两侧的各5面面板和一与此大致铅直平面横交的下部面板。
在大致铅直平面的两侧，有外部面板从下部面板向上伸展，还有外部面板从此向上伸展的外部面板向内伸展，朝着大致上铅直的平面伸展并与之接近。内部面板从此向内伸展的外部面板向下伸展，并朝着下部面板伸展并与之接近。还有内部面板从此向下伸展的内部面板向上且向外伸展，朝着向内伸展的外部面板伸展并与之接近，相对于向下伸展的内部面板成一锐角。还有内部面板从此向上且向外伸展的内部面板向内伸展，朝着向下伸展的内部面板伸展并与之接近。
最好是，在大致铅直平面的两侧并向内伸展的内部面板以粘接方式固定于同侧向内伸展的外部面板上。此外，最好是，在铅直平面两侧并向下伸展的内部面板以粘接方式固定于另侧向下伸展的内部面板上。
理想的是，在大致铅直平面的两侧并从下部面板向上伸展的外部面板向上且向外伸展，与下部面板成钝角。这样，这种码垛货盘支梁从端头观看大致为梯形。
许多这种改进型支梁可以便利地结合许多主要由纸板材料制成的横撑件，诸如披露在上述Schmidtke的专利之中的横撑件，以构成一种主要由纸板制成的码垛货盘。
理想的是，当此改进型支梁所结合的横撑件穿过在各向上伸展的外部面板、各向下伸展的内部面板、以及各向上且向外伸展的内部面板上面的各对中孔眼时，此横撑件以粘接方式固定于各向内伸展的内部面板。最好是，每一向内伸展的内部面板具有一个突舌，突舌伸进至少一个所述孔眼，位于横撑件上方。更好的是，每一向内伸展的内部面板具有多个突舌，伸进在向上伸展的外部面板和向个伸展的内部面板上的各对中的孔眼中，位于横撑件之上。
许多这种改进型的支梁可以另外结合一张上纸板或者上下两张纸板，如同披露于一普通拥有的、共同未决申请-1992年6月30日提出的美国专利申请系列号07/906356之中的那样，以构成一主要由纸板制成的码垛货盘。
无论是使用这些横撑件、这样一上部纸板，或者上下两张纸板，采用这种改进型支梁的主要由纸板制成的码垛货盘都具有高抗压强度和良好的侧向稳定性。
本发明的这些和其他目的、特点、以及优点从以下参照各附图所作的有关本发明的优先实施例的说明中会显而易见。
附图简要说明

图2是主要由纸板制作的码垛货盘的透视图，此盘采用三根按照本发明的改进型支梁，连同三对横撑件。
图3是按照本发明的改进型支梁的端视图，用于图2中的码垛货盘。
图4是一块波纹纸板坯件的平面视图，用于制作图2中码垛货盘的带孔眼支梁。
图5是由图4所示的纸板坯件制成的带孔眼支梁一半的局部放大图。
图6是示于图4所示的纸板坯件的一个边沿的局部放大图。
优选实施例的详细描述
如附图中所示，构成本发明的一项优先实施例的改进型支梁10用来制作一种具有高抗压强度和良好的侧向稳定性的主要由纸板制作的码垛货盘。
这样，在示于图1的一个这样的码垛货盘20之中，三根这样的支梁10结合一块带有两个向下弯折的外侧舌片24的上板22和一块带有两个向上弯折的外侧舌片28的下板26。上下板22、26以及外侧舌片24、28以粘接方式固定于各支梁10。可选择的增强带S以虚线画出。各支梁10除外，码垛货盘20类似于在上述共同末决申请中描述的码垛货盘，其内容作为参考在此引用。
同样，在示于图2的另一这样的码垛货盘30之中，三根这样的支梁10结合三对穿过这些支梁上各个孔眼34的横撑件32。这些横撑件32以粘接方式在各孔眼34的边缘处固定于各支梁10。每一横撑件32都由单张纸板材料，例如用于各支梁10的材料折叠而成，以致具有多面面板，一些这种面板在粘接方式固定于该横撑件32的其他一些面板上。每一横撑件32类似于披露于上述Schmidtke的专利之中的那些横撑件。各支梁10除外，码垛货盘30类似于披露于上述Quasnick和Schmidtke的各专利之中的那些码垛货盘。这些专利的内容作为参考在此引用。
改进型支梁10是由单张双壁的波纹纸板折叠而成的，纸板可以由带状材料或纤维材料加强。另外也可使用单壁、波纹纸板或多层纸板。
在此，指方向的用词，包括“上面的”、“下面的”、“铅直的”、“水平的”、“向上”、“向下”、“向内”、以及“向外”都是有关改进型支梁10和码垛货盘20、30在图中所示的各择优方位。改进型支梁10和码垛货盘20、30也可用于各变化的方位上。这些方向用词并不想把本发明限于上述择优方位。
如图3所示，通过折叠改进型支梁而具有11面面板，亦即在假想的大致铅直平面P两侧的各五个面板和一大致水平的下部面板40，它与平面P横交。还有，如图3所示，下部面板40由平面P等分。最好是，如图所示，改进型支梁是沿着相对于单张波纹纸板各条波纹横向延伸的各平行折叠线折叠而成的。
在平面P的每一侧，外部面板42从下部面板40向上且向外伸展，相对于下部面板40成一钝角。还有，外部面板44从此向上伸展的外部面板42向内伸展，朝着并接近平面P。接着，内部面板46从此向内伸展的外部面板44向下伸展，朝着并接近下部面板40。接着，内部面板48从此向下伸展的内部面板46向上且向外伸展，朝着并接近向内伸展的外部面板44，相对于向下伸展的内部面板46成一锐角。接着，内部面板50从此向上且向外伸展的内部面板48向内伸展，朝着并接近向下伸展的内部面板46。
如图3所示，在平面P两侧的向下伸展的内部面板46以粘接方式在两个面板46之间的一个宽阔区域52之内固定在相对侧的、向下伸展的内部面板46上。同样，在平面P两侧的向内伸展的内部面板50以粘接方式在面板50与面板44之间的一个宽阔区域54之内固定在同侧的向内伸展的外部面板44上。再有，在平面P两侧的向上且向外伸展的内部面板48以粘接方式在靠近同侧的向内伸展的外部面板44的区域56内固定于在同侧的向上且向外伸展的外部面板42。再有，在平面P的两侧用于区域54内的粘接剂和用于区域56内的粘接剂可以连续施加。
最好是，用于区域52、54、56内的粘接剂是一种所谓“冷融化”或“冷凝固”粘接剂，诸如编码第3715号或编码第3715B号，这两种都可在市场上从伊利诺州帕拉泰因的赫·波·福勒公司(H·B·Fuller Co.of Palatine，Illinois)买到。
在示于图2的码垛货盘30中，设定各孔眼34的位置以使各横撑件32刚好在相应各支梁10向内伸展的内部面板50的下面通过。最好是，采用在上一段落中指出的一种粘接剂将各横撑件32的上表面以粘接方式固定于相应各支梁的那些面板50上。
如图3所示，由于每一外部面板42都向上且向外伸展并相对于下部面板40形成钝角，所以，从端头观看改进型支梁10大体上呈梯形。其次，改进型支梁10在从端头观看时在平面P的相对两侧大体上是对称的。
如图4所示，码垛货盘30的一根具代表性的支梁10是这样制成的：压力裁断并沿着图4中各虚线所表明的折叠线折叠一块波纹纸板坯件60，并如前所述，以粘接方式把坯件60的某些面板固定于坯件60的其他一些面板上。在平面P的每一侧，向内伸展的内部面板48具有两个与接纳每一横撑件32的各对中孔眼34相关联的、沿相反方向伸出的突舌，亦即突舌62伸进在同侧的向上且向外伸展的外部面板42上的孔眼34，另一个突舌64伸进在同侧的向下伸展的内部面板46上的孔眼34。其次，采用前述的一种粘接剂将各横撑件32的上部表面以粘接方式固定于突舌62、64以及前述各面板48上。突舌62、64为各横撑件32的粘接固定提供了较大的面积。
码垛货盘20的每一支梁10类似于如上所述的码垛货盘30的每一支梁10，例外的是，孔眼34和突舌62、64可以任意选择而予以去除。在码垛货盘20中，如图1所示，孔眼34和突舌62、64就已经去除了。
无论是带有或者是不带孔眼34和突舌62、64，改进型支梁10与上述Quasnick的专利中所披露的一种具有类似的整体尺寸和具有折叠起来并以粘接方式固定的11面面板的支梁相比，在抗压强度和侧向稳定性方面都占有上风，而且所需材料较少。
改进型支梁10可以用披露于Smith的美国专利第5001991号之中的管状增强件使之更加稳定。
上述的优先实施例中可以作出各种各样的修改而不偏离本发明的范畴和精神。
