Floor coating liquid applying machine
First Claim
1. A machine for applying a liquid floor coating onto a floor surface, said machine comprising:
- a machine body having means for propelling said machine body along said floor surface in a propelling direction;
a liquid feed device movably mounted on said machine body for feeding a floor coating liquid to said floor surface;
a liquid applying member attached to said machine body for applying said floor coating liquid onto said floor surface;
a feed pump attached to said liquid feed device for feeding said floor coating liquid from a liquid tank to said liquid feed device;
said liquid feed device reciprocating along a transverse direction of said machine body;
said feed pump including an elastic pump tube, said elastic pump tube connecting said tank and said liquid feed device,a rotary pump member operatively connected with said elastic pump tube,at least one feed portion disposed in a rotational manner on said rotary pump member, said at least one feed portion being operable in response to rotation of said rotary pump member to elastically deform said elastic pump tube to squeeze out said liquid floor coating contained therein into said liquid feed device; and
at least one receiving portion disposed in an alternate arrangement with said at least one feed portion for causing said elastic pump tube to resile so as to introduce an additional quantity of said liquid floor coating from said liquid tank into said elastic upmp tube.

Abstract
A floor coating liquid applying machine having a propelling machine body, a liquid feed device driven to reciprocate along a transverse direction of the machine body and a liquid feed pump. The feed pump includes an elastic pump tube connecting between a liquid tank and the liquid feed device, a rotary pump member operatively connected with the elastic pump tube, a feed portion disposed along a rotational direction of the rotary pump member, with the feed portion being operable in response to rotation of the rotary pump member for causing the elastic pump tube to elastically deform to squeeze out the liquid therein into the liquid feed device and a receiver portion disposed aside the feed portion for causing the elastically deformed pump tube to resile so as to introduce further liquid from the tank into the elastic pump tube. Also, a blower opening is provided rearwardly of an applying member for feeding to the floor face hot air at about 30 to 90 degrees in Celsius and at the velocity of about 40 to 100 m/sec.
