High pressure cleaning vessel with a space saving door opening/closing apparatus
First Claim
1. A dry cleaning apparatus for removing a contaminant from a substrate using a pressurized cleaning fluid comprising, in combination:
- a substrate cleaning vessel having a door which permits access to the interior of the cleaning vessel,a frame including a base member and at least one side arm attached to the base member for carrying the cleaning vessel door, the base member being slidably attached to the cleaning vessel for substantially horizontal movement relative to the cleaning vessel;
a first actuator carried by the cleaning vessel and operatively connected to the frame for moving the frame in a substantially horizontal direction relative to the cleaning vessel such that the cleaning vessel door moves between a closed position wherein the door engages the opening in the front wall of the cleaning vessel and an intermediate position wherein the door is positioned substantially in front of the cleaning vessel; and
a second actuator carried by at least one of the side arms and operatively connected to the cleaning vessel door for moving the door in a substantially vertical direction relative to the cleaning vessel and the frame between the intermediate position and an open position.

Abstract
An apparatus for opening and closing a door of a pressure cleaning vessel for a dry cleaning system which requires minimal clearance to operate is provided. The apparatus includes a frame slidably attached to the cleaning vessel and having a base member with a pair of attached upstanding side arms which carry the door of the cleaning vessel. The apparatus further includes a first horizontal actuator carried by the cleaning vessel and operatively connected to the frame for moving the frame in a substantially horizontal direction relative to the cleaning vessel such that the door of the cleaning vessel moves between a closed position and an intermediate position wherein the door is substantially in front of the cleaning vessel. A second vertical actuator carried by at least one of the side arms and operatively connected to the door moves the door in a substantially vertical direction relative to the cleaning vessel and the frame between the intermediate position and an open position. Additionally, a shield may be provided on the upper side of the door in order to substantially block access to the area below the cleaning vessel when the cleaning vessel door is in the open position.

-
a substrate cleaning vessel having a door which permits access to the interior of the cleaning vessel, a frame including a base member and at least one side arm attached to the base member for carrying the cleaning vessel door, the base member being slidably attached to the cleaning vessel for movement relative to the cleaning vessel in a direction substantially perpendicular to the front wall of the cleaning vessel, a first actuator carried by the cleaning vessel and operatively connected to the frame for moving the frame relative to the cleaning vessel in a direction substantially perpendicular to the front wall of the cleaning vessel such that the cleaning vessel door moves between a closed position wherein the door engages the opening in the front wall of the cleaning vessel and an intermediate position wherein the door is positioned substantially in front of the cleaning vessel; and a second actuator carried by at least one of the side arms and operatively connected to the cleaning vessel door for moving the door relative to the cleaning vessel and the frame in a direction substantially parallel to the front wall of the cleaning vessel between the intermediate position and an open position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
