Abstract

The present invention is to provide a connecting device for a windshield wiper having no support frame and hook type windshield wiper arm, which comprises a chassis, a saddle hood, a sliding cover and a connector; By means of buckling two insetting juts on the sliding rails with two insetting holes on the left side panel and right side panel of said chassis, said sliding cover can quickly sliding out away said saddle hood in buckling fixed position unable to detach off each other; Thereby, during dismounting and mounting procedure of the hook head on the hook-type wiper arm with said connector, not only without any help in holding said sliding cover from anyone else but also eliminating the interference of bumping from said sliding cover sliding back unwillingly only one person can easily and quickly complete all process.

Claims

1. A connecting device for a windshield wiper having no support frame and hook type windshield wiper arm comprises:

a chassis, which being pressed of rigid metal, comprises a bottom panel, a left side panel and a right side panel, wherein two fixing holes are perforated in said bottom panel;

said left side panel and right side panel being symmetrical and parallel vertical panels having a same shape and being longitudinally juxtaposed apart along first and second long sides respectively of said bottom panel with a horizontal cross fixing spindle straddling thereupon;

a pair of symmetrical and parallel front panels being disposed on a front end of said left side panel and right side panel, respectively, and each having an insetting hole formed therein;

a pair of symmetrical and parallel vertical ledge panels being extended on both front ends of said front panels and each having a top side, each top side having a snap-fitting groove formed therein;

said bottom panel forming first and second long jointing sides, respectively, with said left side panel and right side panel, each long jointing side having a pair buckling grooves formed therein;

a saddle hood, which being an unitary extruded molded hollow cuboid of a plastic material, comprises a left hood panel, a right hood panel, a vertical rear hood panel and a horizontal straddle panel, wherein;

Said left hood panel and right hood panel are a pair of symmetrical and parallel vertical panels of same shape being longitudinally juxtaposed apart;

in which;

A pair of horizontal left and right sliding grooves being formed by two parallel arrays of some juts in up and down juxtaposition, are created on both corresponding insides at a middle section of the saddle hood;

A pair of left and right ceiling ledges are protruded inwards from corresponding top surfaces at the middle section thereupon;

a pair of snap-fitting noses are disposed on each corresponding inside near a bottom edge thereupon to match with said pair of buckling grooves;

Said vertical rear hood panel joins a rear end of each of said left hood panel and right hood panel together to form an integral and continuous closed area;

Said horizontal straddle panel spans across and is joined to said left and right hood panels near a respective front end of each of said left hood panel and right hood panel, such that a open mouthpiece is formed; and

a sliding cover, which being a unitary extruded molded body of a plastic material, comprises a left cover plate, a right cover plate, a front cover plate, a top cover plate, a pair of sliding rails and a pair of pressing tongues, wherein;

Said left cover plate and right cover plate are a pair of symmetrical and parallel vertical panels of same shape being longitudinally juxtaposed apart having front edges and top edges jointed together with the front cover plate and top cover plate respectively;

said pair of sliding rails are symmetrical and parallel and are longitudinally juxtaposed apart extending backwards from corresponding insides at a bottom portion of said left cover plate and right cover plate with each sliding rail having an insetting jut being respectively set near a respective distal free end of each sliding rail;

a pair of symmetrical and parallel elastic buckling hooks juxtaposed apart and extending vertically downwards from an inner side of said top cover plate corresponding to a respective front fixed end of each of said sliding rails thereupon;

said pair of symmetrical and parallel pressing tongues also juxtaposed apart and extending vertically downwards in the inner side adjacent to a rear edge of said top cover plate; and

a connector, which being an unitary extruded molded cuboid of a plastic material, comprises symmetrical and parallel vertical left and right side plates having a same shape and being longitudinally juxtaposed apart and having top edges joined together with a horizontal body plate to define an integral body, wherein;

A pair of symmetrical buckling noses are juxtaposed apart on an inside at a front end of said left side plate and right side plate respectively such that together with said body plate, a containing space is formed;

A round groove with a downwardly facing opening is formed on a front end of said body plate, which is located at a middle section of said left side plate and right side plate.

2. A connecting device as recited in the claim 1, wherein a direction arrow is marked on a top surface of said top cover plate of said sliding cover;

and an anti-sliding grid is respectively formed on an outer surface of said left cover plate and right cover plate.
