Vertical engagement hydraulic tool coupler

A quick release and attachment assembly for coupling a work implement to a construction machine at remote ends of a first member having a lower coupler pin boss and a second member having an upper coupler pin boss, comprising:

• a first attachment means connectable to the work implement;
• a second attachment means releasably connected to the first attachment means, the second attachment means including a body portion and a pair of vertical plates connected to the body portion in a spaced relationship wherein the pair of vertical plates each include a pin mounting opening defined at first and second end portions, the pin mounting openings having a substantially rectangular shape and including a clamp portion extending therefrom and terminating at a pair of spaced flanges defining a coaxial opening therethrough;
• means for connecting the second attachment means to the upper and lower coupler pin bosses including a pair of pins and a bolt assembly, the pair of pins each include a cylindrical central portion extendable through the upper and lower coupler pin bosses and terminating at substantially rectangular end portions fitted within the rectangular shaped openings in each of the pair of vertical plates and the bolt assembly extends through the coaxial openings in each of the spaced flanges for fixing the end portions of the pins within the rectangular shaped openings in each of the pair of vertical plates;
• a retainer mechanism releasably connected on the end portions of the pins for holding the second attachment means on the pair of pins.

A quick release and attachment assembly for coupling a work implement to a construction machine, comprising:

• a first member having a mounting end connectable with the construction machine and a supporting end opposite the mounting end, the supporting end defining a lower coupler pin boss formed at the supporting end and having first and second ends;
• a second member having a mounting end connected with the first member and a supporting end opposite the mounting end, the supporting end defining an upper coupler pin boss integral with the supporting end and having first and second ends corresponding with the first and second ends of the lower coupler pin boss and spaced therefrom;
• and
• a pair of non-connected coupler assemblies each having a housing and a vertical plate fixedly connected to the housing, the vertical plate of one of the pair of coupler assemblies connected respectively at the first ends of the lower and upper coupler pin bosses and the vertical plate of the other of the pair of coupler assemblies connected respectively to the second ends of the lower and upper coupler pin bosses to define a spatial relationship between the pair of coupler assemblies extending between the vertical plates, the connection between the pair of coupler assemblies and the lower and upper pin bosses being such that the lower and upper pin bosses extend completely across the spatial relationship between the pair of coupler assemblies for abutment of the respective first and second ends of the lower and upper pin bosses with the respective vertical plates.
