Abstract

一种电动机器3的控制踏板7,包括一连到脚支承板11且由使用者的脚操纵的可动部件9,使用者的脚跟放在脚支承板10上。当踏板7不用时,部件9降到靠在板10上,而电线8和带有插头6的电线则卷绕在作为绕线架的部件12上。

Description

电动机器的控制踏板是人们所熟知的,特别是缝纫机的控制踏板,它包括一外壳和一用使用者的脚来驱动的可动部件,这一部件作用在一可操作和调节机器速度的可变电元件上;有一根电线将踏板连到机器上。
本发明的一个目的在于使该种类型的踏板变得更为实用。
为此目的,构成本发明目的的踏板特征在于所述的部件(踏板)由能占据两个位置的一踏杆构成,其中一个位置用于运送踏板,另一位置用于控制缝纫机的速度。
附图所示为根据本发明的踏板的一个实施例。此实施例仅作说明本发明之用,不构成对本发明的限制。
图1所示为一装有本发明踏板的缝纫机。
图2所示为该踏板的侧示图。
图3所示为该踏板内部机构一部分的详细示图。
图4所示为该踏板的平面图,其中部分被剖开。
如图1所示的缝纫机和通常一样包括一底盘1,一下臂2,一竖直部分3和一带有压脚5的上臂4。
电动机器通过一插入电输出口的插头6通电,将电流供给控制踏板7,控制踏板通过电线8与缝纫机的电动机相连。
踏板7具有一通过使用者的脚操纵的可动部件9,使用者的脚跟一般放在支承板10上。这一部件9能操作机器并调整缝纫速度。
踏板7包括一外壳11,在此外壳的两侧面上各有一部件12,部件12构成可在其上分别卷绕带有插头6的电线和电线8的绕线架。
图2所示踏板7处于非使用位置,踏杆式部件9降低到板10的上方。从图中还可看到电线8卷绕在作为绕线架的部件上。最后,图2还用虚线表示出了部件9的使用位置的两个极限位置,即位置9a对应于机器的停止位置,位置9b对应于机器最大速度位置。
如图3和图4所示,可动部件9呈U形,它包括一中心杆13和两侧杆14,后者的自由端通过一杆15互连。该杆在与外壳11的侧壁连成一体的支承套16和17内作枢轴旋转。
杆15带有两凸轮18和19。
凸轮18作用在开关20上,当踏板不工作时部件9从其移至位置9a处于可运送和使踏板定位的位置时,它就作用在开关上以切断机器的供电。这样就获得了较高的安全性,可以防止机器不适时的开动,例如在使电动机通电的电元件发生故障的情况下。
呈手指形状的另一凸轮19延伸而作用在例如电位计的销子21上,销子通过位于壳体23内的弹簧22向上偏置。
可以看到,杆15还带有一具有一盲孔25的圆盘24,盲孔25中容纳一受弹簧力27作用的圆珠26,圆珠与套筒16上的一插口28啮合。
该装置形成一弹性扣爪装置以保持部件9在其运送位置内。
上述控制踏板是联系其在缝纫机上的应用而描述的,不用说,它不仅能用于上述缝纫机中,也可应用于由控制踏板控制操作的任何装置或机器上。
本发明在生产中可以有多种变化,在机器由电输出口直接供电的情况下,必须用一根电线将踏板与缝纫机相连。

Claims (5)
