摘要： A floor sweeper is constructed from a single integral plastic housing having a top and downwardly extending rear and end walls. The front end portion of the housing is uniquely formed with the front edge of the top set back from the sweeper periphery, said edge merging into an integral deflector which extends downwardly beneath the housing adjacent the rotary brusy. The lower extremity of the deflector is connected to the front peripheral housing portion by an integral platform which, together with the deflector, forms an elongated transversely extending trough-like channel on the upper exposed side of the housing front end. The channel has end walls which are spaced inwardly from the housing end walls to form downwardly facing wheel-receiving recesses. The front sweeper wheels are freely mounted on the ends of an axle which extends through the channel and its end walls, with the wheels being trapped within their respective recesses. The channel is provided with a removable cover of flexible stretchable material, both for appearances sake and to prevent dust and debris from entering the channel. The cover is resilient and further serves as a bumper for the front of the sweeper. A dust pan is disposed behind the rotary brush, with the top side of the pan bottom forming a floor having a raised transverse rib which helps prevent shifting of dust and debris either toward or away from the brush. The under side of the rib beneath the pan forms a slot which receives the axle for the rear sweeper wheels.
摘要翻译：地板清扫机由具有顶部和向下延伸的后壁和端壁的单个整体塑料外壳构成。外壳的前端部分是唯一地形成有从清扫器周边设置的顶部的前边缘，所述边缘汇合成一体的偏转器，该偏转器在壳体的下方向下延伸，邻近旋转的刷子。偏转器的下端通过一体的平台连接到前周边壳体部分，该平台与偏转器一起在壳体前端的上部暴露侧上形成细长的横向延伸的槽状通道。通道具有从壳体端壁向内隔开的端壁，以形成向下的轮容纳凹部。前清扫车轮自由地安装在轴的端部上，车轴通过通道及其端壁延伸，车轮被捕获在它们各自的凹部内。通道设置有柔性可拉伸材料的可移除盖，用于外观，并防止灰尘和碎屑进入通道。盖子是弹性的，并且还用作清扫机前部的保险杠。一个防尘盘设置在旋转刷的后面，锅底的顶侧形成具有升高的横向肋的底板，这有助于防止灰尘和碎屑朝向或远离刷子移动。在锅底下方的肋的下侧形成一个槽，其接收用于后部清扫车轮的车轴。
