Abstract
A coupling member for joining a first article to a second article comprising first and second elongate arms that are pivotally connectable to a main housing via ball and socket joints. Each arm has one end formed for connection to one of the articles and the other end adapted to be engaged in the ball and socket joint. A locking system is also provided to lock the arms in position with respect to the main housing after the arms have been connected between the first and second articles to create a rigid connection between the first and second articles. The pivotable nature of the coupling member allows for a connection to be made between the first and second articles to be joined without the articles being in perfect alignment whereupon the locking system is applied to create a rigid link.
Claims13
In a coating machine having a coating blade for applying a coating to a surface an elongate, flexible backing bar to support the coating blade, and a plurality of actuators for applying distorting forces along the length of the backing bar, the improvement comprising:
- a plurality of coupling members for joining the backing bar to the actuators, each coupling member comprising:
- first and second elongate arms, each having first and second ends, the first end of the first arm being adapted for attachment to the backing bar and the first end of the second arm being adapted for attachment to one of the plurality of actuators;
- a rigid main housing for joining the second ends of the first and second arms;
- a joint for pivotally connecting each of the arms to the main housing;
- and
- locking means to lock the arms in position with respect to the main housing to create a rigid connecting link having a generally longitudinal axis defined by the first and second arms for transmission of forces along the longitudinal axis between the backing bar and the one of the plurality of actuators.
In a coating machine having a coating blade for applying a coating to a surface, an elongate, flexible backing bar to support the coating blade, and a plurality of actuators for applying distorting forces along the length of the backing bar, the improvement comprising:
- at least one coupling member for joining the backing bar to an actuator comprising:
- a rigid main housing formed with joint means;
- first and second elongate arms, each arm having two ends, one end of each arm formed for connection to a different one of the backing bar and the actuator and the other end of each arm being adapted to be engaged with the joint means to permit pivotable movement of each arm with respect to the main housing;
- and
- locking means to lock the arms in position with respect to the main housing to create a rigid member having a generally longitudinal axis defined by the first and second arms for transmission of forces along the longitudinal axis between the backing bar and the actuator.
In a coating machine having a coating blade for applying a coating to a surface, an elongate, flexible backing bar to support the coating blade, and a plurality of actuators for applying distorting forces along the length of the backing bar, the improvement comprising:
- a coupling member for joining the backing bar to one of the plurality of actuators, the coupling member comprising:
- an elongate arm having ends adapted for connection to each of the backing bar and the one of the plurality of actuators;
- a joint assembly intermediate the ends of the arm that divides the arm into first and second portions and permits independent pivotal movement of each portion;
- and
- locking means to lock the arm portions into position with respect to the joint assembly to create a rigid member having a generally longitudinal axis defined by the arm portions for transmission of forces along the longitudinal axis between the backing bar and the one of the plurality of actuators.
