- a user Prior to entering the interior cavity 60 of the tub 10, a user first rotates the handle 250, 410 to ensure that the latching mechanism 240, 400 is in the unlatched position such that the door 140 can be swung open into the interior cavity 60. After opening the door 140 to allow ingress, the user may step into the interior cavity 60 of the tub 10. The door 140 is then moved to the closed position by swinging the door 140 toward the sealing face 130 of the door frame 120. As the door 140 nears the sealing face 130, the seal 170 contacts the sealing face 130. Continued movement of the door 140 toward the sealing face 130 causes the seal 170 to be compressed.
- the user turns the handle 250 to activate the latching mechanism 240, 400 and close the door 140 to create a watertight connection between the door 140 and the sealing face 130 of the door frame 120.
- Engaging the latching mechanism 240, 400 into the latching position causes the rods 270, 430 to extend away from the door cavity.
- Linear movement of the rods 270, 430 causes the latching pins 290, 480, 530 to engage the central opening of the pin receiver such that the door 140 is further drawn toward the sealing face 130.
- This causes the seal 170 to be compressed even further, thereby establishing a watertight connection that prevents leakage of water from the interior cavity 60 outside the tub 10.
