Don't know the given name but in my book it refers to mass produced quick bolted corner joint. Although it may be an extreemely strong jointing of the legs to rails, It is of course easy to break down when moving is necessary, but as for WWing joinery, I call it quick, easy, fast, & cheap... I have one table in my house with such leg joints and it is my grandaughter's tea set.
