[41] 参见图 2至图 11所示, 该顶踏板结构 100包括:
[42] 一块拼装铝件 1, 该拼装铝件 1由三块铝件单体即前铝件单体 11、 中铝件单体 12 、 后铝件单体 13前后拼接而成, 在拼装铝件 i的前后端分别设有向下的边裙, 前 边裙 111设在前铝件单体 11的前侧, 后边裙 131设在后铝件单体 13的后侧;
[43] 一金属管组件 2, 该金属管组件 2是由一根直杆形状的管条釆用弯管机来弯成 U 形形状, 该金属管组件 2垫在拼装铝件 1的前侧边缘及两侧边缘的底端并处于拼 装铝件前边裙 111的内侧, 金属管组件 2与拼装铝件 1的两侧端边固定相连接; [44] 二个侧塑料件 3, 二侧塑料件 3分别卡套在金属管组件 2与拼装铝件 1的组合体的 两侧边, 并完全包覆于拼装铝件的前边裙 111与后边裙 131之间的两侧空隙。
[45] 其中:
[46] 金属管组件 2可以为铁材料的管条制作而成, 也可以为铝材料的管条制作而成
[47] 在每个铝件单体即前铝件单体 11、 中铝件单体 12、 后铝件单体 13的上端分别设 有由挤压方式成型的若干条沿横向而设的凸条 10;
[48] 在每个铝件单体即前铝件单体 11、 中铝件单体 12、 后铝件单体 13的上端面分别 设有多个按一定方式排列的且是由挤压方式成型的印花结构 14, 该印花结构 14 为菱形形状, 其菱形形状是相对于铝件单体 (即前铝件单体 11、 中铝件单体 12 、 后铝件单体 13) 的上端面向下凹陷;
[49] 侧塑料件 3的上、 下分别设有上包边 31、 下包边 32, 其上包边 31设有多个可对 应让位于铝件单体的凸条 10的缺口 311;
[50] 拼装铝件 1端边与金属管组件 2之间釆用抽芯铆钉 4铆接相固定; 侧塑料件 3的上 包边的内侧则对应设有多个用来让位于铆钉 4钉头的凹部 312;
[51] 铝件单体即前铝件单体 11、 中铝件单体 12、 后铝件单体 13分别为单层结构体;
[52] 相拼接的相邻两块铝件单体的相接边上分别设有开口向内的侧 U形端部, 前铝 件单体 11的后边与中铝件单体 12的前边相拼接, 因此, 在前铝件单体 11与中铝 件单体 12的相接边分别设有侧 U形端部 51, 即前铝件单体 11的后侧边设为侧 U形 端部 51, 中铝件单体 12的前侧边设为侧 U形端部 51, 前铝件单体 11后侧的侧 U形 端部 51与中铝件单体 12前侧的侧 U形端部 51对钩在一起而使前铝件单体 11与中铝 件单体 12拼接在一起; 同样, 中铝件单体 12的后边与后铝件单体 13的前边相拼 接, 中铝件单体 12的后边与后铝件单体 13的前边也分别设有可相互对钩的侧 U形 端部, 使中铝件单体 12与后铝件单体 13拼接在一起; 前铝件单体 11、 中铝件单 体 12、 后铝件单体 13相互拼接后即构成拼装铝件 1 ;
[53] 在相拼接的相邻两块铝件单体的相接边上还分别设有多个可相配合的卡口, 即 在前铝件单体 11的后侧边设有卡口 521, 在中铝件单体 12的前侧边设有卡口 522 , 当前铝件单体 11的后侧边与中铝件单体 12的前侧边相配合吋, 前铝件单体 11 的卡口 521对应配合于中铝件单体 12的卡口 522; 中铝件单体 12的后侧边与后铝 件单体 13的前侧边也有相互配合的卡口结构; 一小塑料盖 41用来盖在后铝件单 体 13的开孔 132处。
[54] 本发明的一种简易铝梯的顶踏板结构, 是由拼装铝件 1、 侧塑料件 3、 金属管组 件 2组装而成。 拼装铝件 1由三块铝件单体即前铝件单体 11、 中铝件单体 12、 后 铝件单体 13拼接而成, 这样, 就使得每块铝件单体的宽度较小, 使铝件单体可 以在较小吨位的铝挤压机上进行加工, 当铝件单体的角部作为拼装铝件的角部 而需要加工成圆角吋, 可以釆用冷冲压的方式进行加工。 金属管组件 2可以为铁 材料的管条制作而成, 也可以为铝材料的管条制作而成; 金属管组件 2的形状为 U形状, 是由一根直杆形状的管件釆用弯管机来弯成 U形形状, 当然, 也可以是 H形状或框形状或两根单管, 这几种形状都有至少两根管条可以分别垫在拼装铝 件 1的两侧边缘, 金属管组件 2为 U形形状后, 其三边刚好对应于拼装铝件 1的前 边和两侧边; 金属管组件 2的两侧管条可以与拼装铝件 1的两侧端边固定起来, 形成金属管组件 2与拼装铝件 1的组合体, 拼装铝件 1与金属管组件 2相固定吋, 是釆用铆钉 4方式固定, 当然, 也可以釆用其他冷冲压方式固定。 侧塑料件 3是 釆用注塑方式加工而成, 起封边的作用, 侧塑料件 3设有上包边 31、 下包边 32, 这样, 就使塑料件 3形成有凹口, 可以利用该凹口卡套在金属管组件 2与拼装铝 件 1形成的组合体的两侧边, 将拼装铝件 1的前边裙 111、 后边裙 131之间的两侧 空隙完全包住, 使顶踏板 100更加美观, 同吋, 也减少了铝材料的使用量, 降低 了产品的制作成本。 在铝件单体的表面 (即上端面) 设有多个按一定方式排列 的且是由挤压方式成型的印花结构 14, 可以是几何形状的结构比如菱形, 也可 以是三角形、 圆形等, 还可以是其他的结构比如花朵结构等, 这些印花一方面 使顶踏板更具美感, 另一方面也具有防滑的作用, 这些印花结构可以按直线进 行排列, 也可以按曲线进行排列, 或按照需要的方式进行排列。 在铝件单体的 上端设有由挤压方式成型的若干条沿横向而设的凸条 10, 这些凸条 10同样也具 有美观和防滑的双重作用, 同吋还便于侧塑料件 3的卡套。
[55] 制作吋, 先根据拼接的需要分别加工制作出三块铝件单体即前铝件单体 11、 中 铝件单体 12、 后铝件单体 13, 包括在铝件单体上加工出凸条 10、 印花结构 14、 拼接边结构以及需要的边裙等结构, 并将一根金属管条弯成金属管组件 2即 U形 形状; 然后将三块铝件单体拼成整块即拼成拼装铝件 1, 将拼装铝件 1与金属管 组件 2组合在一起, 并将拼装铝件 1的两端边与对应的金属管组件 2的两侧管条固 定在一起而构成金属管组件与拼装铝件的组合体, 最后再将两侧塑料件 3分别卡 套在金属管组件 2与拼装铝件的组合体的两端边, 利用侧塑料件 3包覆于拼装铝 件 1的前边裙 111、 后边裙 131之间的两侧空隙, 构成一顶踏板结构 100。
[56] 实施例二, 参见图 12所示, 本发明的一种简易铝梯的顶踏板结构, 与实施例一 的不同之处在于, 没有金属管组件, 顶踏板结构仅由拼装铝件 1和侧塑料件 3复 合制成, 由于不需要金属管组件, 因此, 也不需要铆钉来对拼装铝件和金属管 组件进行固定。
[57] 实施例三, 参见图 13至图 14所示, 本发明的一种简易铝梯的顶踏板结构, 与实 施例一的不同之处在于, 相拼接的相邻两块铝件单体中, 第一铝件单体 (即前 铝件单体 11) 的相接边上设有竖钩 61, 第二铝件单体 (即中铝件单体 12) 的相 接边上设有开口向上的 U形端部 62, 第一铝件单体 (前铝件单体 11) 的竖钩 61插 在第二铝件单体 (中铝件单体 12) u形端部 62的 U形口内而使相邻的前铝件单体 1 1与中铝件单体 12拼接在一起。
[58] 中铝件单体 12与后铝件单体 13的拼接处也釆用相同的结构拼接在一起。
[59] 实施例四, 参见图 15至图 16所示, 本发明的一种简易铝梯的顶踏板结构, 与实 施例一的不同之处在于, 相拼接的相邻两块铝件单体中, 第一铝件单体 (即中 铝件单体 12) 的相接边上设有开口向上的 U形端部 71并向外延伸有横钩 711, 第 二铝件单体 (即前铝件单体 11) 的相接边上设有开口向内的侧 U形端部 72并向下 延伸有竖钩 721, 第一铝件单体 (即中铝件单体 12) 的横钩 711配合在第二铝件 单体 (即前铝件单体 11) 的侧 U形端部 72的 U形口内, 第二铝件单体 (即前铝件 单体 11) 的竖钩 721配合在第一铝件单体 (即中铝件单体 12) 的 U形端部 71的 U形 口内, 使前铝件单体 11与中铝件单体 12拼接在一起。
[60] 中铝件单体 12与后铝件单体 13的拼接处也釆用相同的结构拼接在一起。
[61] 实施例五, 参见图 17至图 19所示, 本发明的一种简易铝梯的顶踏板结构, 与实 施例一的不同之处在于, 铝件单体即前铝件单体 11、 中铝件单体 12、 后铝件单 体 13分别为具有一个或多个管腔的双层结构体, 同吋, 由于双层结构其强度比 单层结构要强, 因此, 可以不要金属管组件, 当需要金属管组件进一步加强顶 踏板的强度吋, 可以选用两根单管条, 插在拼装铝件 1两侧边的管腔中, 当然, 也可以选用 H形状或 U形状或框形状的结构, 把金属管组件垫在拼装铝件 1的底端 实施例六, 参见图 20至图 21所示, 本发明的一种简易铝梯的顶踏板结构, 与实 施例一的不同之处在于, 铝件单体即前铝件单体 11、 中铝件单体 12、 后铝件单 体 13分别为具有一个或多个管腔的双层结构体, 同吋, 由于双层结构其强度比 单层结构要强, 因此, 可以不要金属管组件, 当需要金属管组件进一步加强顶 踏板的强度吋, 可以选用两根单管条, 插在拼装铝件 1两侧边的管腔中, 当然, 也可以选用 H形状或 U形状或框形状的结构, 把金属管组件垫在拼装铝件 1的底端 且相拼接的相邻两块铝件单体中, 第一铝件单体 (即中铝件单体 12) 的相接 边上设有开口向上的 U形端部 71并向外延伸有横钩 711, 第二铝件单体 (即前, i 件单体 11) 的相接边上设有开口向内的侧 U形端部 72并向下延伸有竖钩 721, 第 一铝件单体 (即中铝件单体12) 的横钩 711配合在第二铝件单体 (即前铝件单体
