Abstract

There is a joining slot under the connector, which matches the joining shaft of the framework. And there is also a socket in one end of the connector for a flat swing bar to be fixed in the connector. And in the other end of the connector is an inner fastening slot and an outer one, which is designed for the swing bar with a hook end to be fixed in the connector. Besides, there is an arc socket under the arc transverse part, with an active bolt, the swing bar with fixed jack can be connected and fixed. Because of the above-mentioned structure, the connector matches swing bars of different types to be fixed in the windshield wiper framework, and so it has great flexibility for use.

Claims

1. A windshield wiper arm connector, comprising:

an arc-shaped transverse part, a first fastening slot being formed in a lower portion of said arc-shaped transverse part, said first fastening slot being adapted to receive a connecting shaft of a windshield wiper arm, said arc-shaped transverse part further having an arced inserting slot in the lower portion thereof, the arced inserting slot receiving a pin therein for fastening said arc-shaped transverse part to the pin, so as to fix a pin-type wiper arm to the connector;

first and second side sheets disposed on opposite sides of said arc-shaped transverse part;

a spring slice formed on a rear side of said arc-shaped transverse part, and being located between said first and second side sheets;

a structure slice disposed between said first and second side sheets and above said spring slice, said structure slice having a positioning hole therein, said structure slice and said spring slice forming a socket therebetween for receiving a flat-end type wiper arm therein, wherein when the flat-end type wiper arm is received within the socket, a projecting point of the flat-end type wiper arm is receivable within the positioning hole to fix the flat-end type wiper arm in the connector;

first and second projecting blocks, each being disposed below said arc-shaped transverse part in a region in front of the first fastening slot, and each being attached to an inner side of a respective one of said side sheets, said first and second projecting blocks and said arc-shaped transverse part forming an inner fastening slot therebetween, a region outside of said first and second projecting blocks defining an outer fastening slot;

first and second baffle slices, each being disposed in front of a respective projecting block and in front of said arc-shaped transverse part, and each being attached to the inner side of a respective one of said side sheets, wherein a first sized hook-end type wiper arm is attachable to the connector by disposing a free leg of the hook-end type wiper arm in the inner fastening slot, and a second sized hook-end type wiper arm is attachable to the connector by disposing a free leg of the second sized hook-end wiper arm in the outer fastening slot, and wherein said baffle slices abut against an outer surface of a curved portion of the respective hook-end type wiper arm, and said arc-shaped transverse part abuts against an inner surface of the curved portion of the respective hook-end wiper arm, when said first sized hook-end type wiper arm is attached to the connect or and when said second sized hook-end type wiper arm is attached to the connector, to fix the respective hook-end type wiper arm to the connector.
