Supporting mechanism of side washing brush in car washing device

Abstract

Abstract PURPOSE:To make it possible to add abutting pressure of being substantially constant on front and rear sides of a vehicle, by swingably supporting bearing means, adapted to hold a pair of rotary shafts of right and left side washing brushes, by means of a pallalelogram link via shafts, which are horizontal and perpendicular to the moving direction of a running frame. CONSTITUTION:In a running frame 1, which runs on tracks 25, 25' by means of driving wheels 11, 11' and follower wheels 12, 12', a pair of right and left main swing arms 15, 15' and a pair of right and left sub-swing arms 16, 16 are supported respectively by pairs of perpendicular shafts 17, 17' and 18, 18'. A pair of link elements 14, 14' are supported by perpendicular shafts 19, 19; and 20, 20' at respective tip ends of arms 15, 15' and 16, 16' to from pallalelogram links. The link elements 14, 14' are adapted to rotatably support horizontal shafts 6, 6' held fixedly by bearing means 3, 3', which hold the rotary shafts of side washing brushes 2, 2'. Between the arms elongated vertically from ends of the horizontal shafts 6, 6', and the link elements 14, 14'. a pair of upper and lower compression springs 24, 24' are interposed so as to hold the washing brushes 2, 2' such that they are in their vertical positions.
