Abstract: A cover opening and closing mechanism includes a first cover member having a first sheet placing surface and a second cover member having a second sheet placing surface. The first cover member has a first engagement part at a distal end of the first sheet placing surface, the second cover member has a second engagement part at a distal end of the second sheet placing surface so that the first sheet placing surface is flush with the second sheet placing surface. During a process in which the first cover member swings in a close direction, a first contact part of the first cover member, which is other than the first sheet placing surface, contacts to a second contact part of the second cover member, which is other than the second sheet placing surface, before the first engagement part contacts to the second engagement part.

Abstract: A vending machine includes a storage/display region, a dispensing chamber including a product access opening, and an anti-pilfer device that prevents unauthorized removal of products from the storage/display region through the product access opening. A delivery door is provided which can be shifted from a closed position to an open position to enable the removal of products from the dispensing chamber. The anti-pilfer device includes a plate coupled to a lower portion of the delivery door. When the delivery door is moved from the closed position, the anti-pilfer plate shifts, over a guide element, into a position that prevents products from being withdrawn from the storage/display area. Preferably, the storage/display region and dispensing chamber are separated by a product door, with the anti-pilfer plate preventing the product door from opening when the delivery door is shifted from the closed position.

Abstract: A method for deactivating a defective door of a train. The method steps include: providing a first door and a first controller; providing a second door and a second controller; providing a separate remote, central activation device configured to transmit an activation signal; determining that a fault has occurred at the second door; and deactivating the second door by an activation signal transmitted from the remote, central activation device via the first controller.

Abstract: A door operating device of an air conditioner for an automobile may include a cam plate which is rotatably connected to a stationary member to rotate according to a conversion of an air conditioning mode, and a plurality of rotation lever, one end of which is coupled to respective mode door and the other one end of which is connected to a guide member formed to the cam plate to guide movement of the other end of the rotation lever in response to rotation of the cam plate, the mode doors being pivotally coupled to the stationary member, wherein opening amounts of respective mode door are regulated according to a rotation angle of the cam plate which rotates by a control member to convert the air conditioning mode.

Abstract: An access system for a building structure includes an access opening formed in the structure and a horizontally oriented track extending across the opening. Panels are slidably mounted on the track. A pulley—track system opens and closes the panels. The system is controlled with a manually operated control panel mounted on the building structure.

Abstract: A storm door (20) ventilation through a screen (50) by either or both of slidable sashes (92, 93). The storm door may also utilize a flexible member (80) to secure a liner (30, 40, 53, 54) to a side, without the use of mechanical fasteners. Sash weight balancing assemblies are utilized in a three track door.

Abstract: A vending mechanism for a cylindrical article dispenser of a type having a column of stacked cylindrical articles moved along a dispensing pathway by a force, such as by the force of gravity, is disclosed, which has an escapement mechanism which is attachable in operative alignment with a vending pathway of a column of stacked cylindrical articles. An upstream arm is pivotably attached in the escapement mechanism, having a first position blocking a portion of the vending pathway and having a second position retracted from the vending pathway to allow cylindrical articles to move past the upstream arm. A downstream arm is pivotably attached in the escapement mechanism, having a first position blocking a portion of the vending pathway and having a second position retracted from the vending pathway to allow cylindrical articles to move past the downstream arm.

Abstract: A vehicle ventilation opening is covered by a dome-shaped cover that has a pair of generally triangular oppositely disposed lateral cover openings extending from an uppermost portion of the cover. A pair of generally triangular shaped and outwardly bowed resilient doors are pivoted at opposite sides of the cover so that their adjacent but mutually spaced free end portions move between an inwardly displaced open position and a closed position wherein the free ends of the doors are at the high point of the domed cover and the doors seal against the inside of the cover at the peripheries of the openings.
