Abstract

螺旋状加热软管(10、12)利用两个特征来增加柔性。第一个特征是编织的铜加热元件(14)，所述编织的铜加热元件(14)相对于现有技术的固体铜加热元件具有增大的柔性。所述元件螺旋形地缠绕软管，且利用防湿层(16)保持在适当的位置。第二个特征为螺旋状扭结(18)，所述螺旋状扭结(18)就位于软管(10、12)附接到歧管(20)的点之前。螺旋状特征通过螺旋状支撑件(22)产生，所述螺旋状支撑件(22)从终止点向后大约24英寸处开始扭曲。螺旋特征的作用是减少围绕两个供应软管(10、12)的中性轴线(26)的惯性力矩。

Description

螺旋状加热软管
技术领域
本申请要求于2007年9月11日提交的序号为60/971,346的美国申请的优先权，其内容在这里通过参考并入本发明。
背景技术
需要加热软管用于喷射各种材料，比如快速凝固的泡沫。这种软管往往相对缺乏柔性并且使操作者难于控制。
发明内容
螺旋状加热软管利用两个特征来增加柔性。第一个特征是编织的铜加热元件，所述编织的铜加热元件相对于之前的固体铜加热元件具有增大的柔性。所述元件螺旋地缠绕软管，且利用防湿层保持在适当的位置。第二个特征是螺旋状扭结，所述螺旋状扭结就位于所述软管附接到歧管的点之前。螺旋状特征通过螺旋状支撑件产生，所述螺旋状支撑件从终止点向后大约24英寸处开始扭曲。螺旋状特征的作用是减少围绕两个供应软管的中性轴线的惯性力矩。为使传统的加热软管弯曲，一个供给软管必须在另一个供应软管处于张紧状态时压缩。通过在弯曲期间使软管彼此交叉并滑过，弯曲期间唯一的刚性感觉来自软管本身的刚度。
螺旋状加热鞭状软管的优点是，从左到右枢转喷枪所需的力从20磅(lbs)力降低到5磅力。这种力的降低会使喷洒设备具有防止臂腕疲劳的有益效果。测试结果显示，相对于类似结构的不带有螺旋状特性的软管，在柔性上的增加达到了400％。
根据以下结合附图作出的说明，本发明的这些和其他目的和优点将更加充分地显现，其中在所有附图中相同的附图标记表示相同或相似的部件。
附图说明
图1示出本发明的螺旋状加热软管。
图2示出螺旋状支撑件。
具体实施方式
第一螺旋状加热软管10和第二螺旋状加热软管12利用两个特征来增加柔性。第一个特征是编织的铜加热元件14，所述编织的铜加热元件14相对于现有技术的固体铜加热元件具有增大的柔性。所述元件螺旋地缠绕软管，且利用防湿层16保持在适当的位置。第二个特征是螺旋状扭结18，所述螺旋状扭结18就位于软管10和12附接到歧管20的点之前。螺旋状特征通过螺旋状支撑件22产生，所述螺旋状支撑件22从终点向后大约24英寸处开始扭曲。螺旋状特征的作用是减少围绕两个供应软管10和12的中性轴线26的惯性力矩。为使传统的加热软管弯曲，一个供应软管必须在另一个供应软管处于张紧状态时压缩。通过在弯曲期间使软管彼此交叉并滑过，弯曲期间唯一的刚性感觉来自软管本身的刚度。
螺旋状加热鞭状软管的优点是，从左到右枢转喷枪所需的力从20磅力降到5磅力。这种力的降低会使喷洒设备具有防止臂腕疲劳的有益效果。测试结果显示，相对于类似结构的不带有螺旋状特性的软管，在柔性上的增加达到了400％。
可预期的是，可以对于加热软管进行各种改变和改进，而不偏离如通过以下权利要求限定所限定的本发明的精神和范围。

Claims (4)
