Abstract
A sliding door and floor guide assembly including a floor guide and at least one door panel including a pin guide assembly, and a guide shoe. The guide shoe has a curved bottom surface and the rail has a corresponding curved upper surface so that the two surfaces can engage one another. The pin guide assembly includes a spring that exerts a downward force to keep the guide shoe and rail in contact with one another. The guide shoe also includes at least one beveled surface adjacent the region where the guide shoe and rail engage. This beveled surface causes debris on the rail to be moved away from the rail when the door is opened or closed so that the debris does not interfere with the operation of the sliding door.
Claims18
A sliding door comprising:
- a door panel;
- a floor guide;
- a pin guide assembly connected with a bottom of the door panel;
- a guide shoe connected with the pin guide assembly;
- and
- a lock-stop connected with the floor guide;
- wherein the guide shoe includes a concave mating surface, wherein the floor guide includes a rail having a convex mating surface shaped to correspond with the mating surface of the guide shoe, wherein the mating surfaces of the guide shoe and floor guide are in sliding contact with one another, wherein the guide shoe further comprises two beveled surfaces on opposing terminal ends of the guide shoe arranged along a direction of travel of the guide shoe along the rail;
- and wherein at least one of the beveled surfaces of the guide shoe engages with an engagement surface of the lock-stop to prevent the guide shoe from disengaging from the floor guide, such that when the at least one beveled surface is engaged with the engagement surface at least a portion of the beveled surface is between the engagement surface and the floor guide.
