A coupling instrument is provided that can easily attach or detach a main body to or from a cleaning part in a cleaning device. The coupling instrument includes a first coupling member including a bulging part having a slant part. A side peripheral part of the slant part is tapered toward a tip thereof. A first protruding part is formed in a protruding manner around the bulging part. The coupling instrument further includes a second coupling member including a fitted part in which the bulging part can be loosely fitted, and a second protruding part formed in a protruding manner around the fitted part. The second protruding part is adjacent to the first protruding part; and the second coupling member has a plurality of engaging parts arranged around the fitted part.

A surface maintenance vehicle with a compact cleaning head lift mechanism and suspension. The cleaning head lift mechanism and suspension adjust a scrub head to an operational mode and a transport mode, yet remain compact such that they are confined to specific areas of the surface maintenance vehicle.
摘要:
A device and method for regulating the pressure between a floor cleaning implement (22) and a floor, wherein the floor cleaning implement (22) is coupled to a floor cleaning machine (10). The device of one embodiment comprises a cantilevered arm (28) coupled to the floor cleaning machine (10) and a sensor (30) coupled to the cantilevered arm (28) and positioned to sense deflection or other deformation of the cantilevered arm (28). An actuator (26) is coupled between the cantilevered arm (28) and cleaning implements (22). The actuator (26) is also coupled to the sensor (30) and adapted to receive signals from the sensor (30) to cause actuation of the actuator (26). When pressure other than a predetermined amount causes the cantilevered arm (28) to deform, the sensor (30) senses this deformation and cause the actuator (26) to actuate in a direction that allows the cantilevered arm (28) to return to a position in which the pressure is within the predetermined amount.
摘要:
A riding apparatus for treating a floor surface has a main steering and drive wheels and a forwardly located seat for an operator and at least one foot rest for feet of the operator. The vehicle has a polishing and cleaning deck mounted in front of the vehicle and is operably connected to the main vehicle. A clearance gap is formed between the vehicle and the polishing and cleaning deck. The at least one foot rest has a gap therebetween for providing a line of sight for the operator through the gap to view the floor surface directly behind the deck.
