A door assembly for an aircraft includes a door, a door handle, a door hinge, a support assembly, and a lifting assembly. The door handle is rotatable between an unlatched position and a latched position. The support assembly rotatably mounts the door hinge to the door. The lifting assembly includes a latch cam, a lift track, and a latch idler. The latch cam is mounted to the door handle. The latch cam is rotatable with the door handle about the door handle rotational axis. The latch cam forms an eccentric roller path extending about the door handle rotational axis. The latch idler includes a first roller and a second roller. The first roller is disposed on a lift track of the support assembly and configured to roll along the lift track. The second roller is disposed within the eccentric roller path. The latch idler is mounted to the door. The latch idler is configured to lift the door as the door handle rotates from the latched position to the unlatched position.

Enclosures for an electrical apparatus include a housing comprising a back and first and second spaced apart sidewalls extending outwardly from the back and providing an interior space and a door pivotably attached to the housing, the door having a primary body with a bottom having a bottom flange and first and second laterally spaced apart side flanges. The bottom flange and the side flanges have a folded inwardly extending edge joining first and second parallel wall segments that are orthogonal to the primary body of the door. The enclosure can also include at least one slot extending through the first and second parallel wall segments of the bottom flange and/or a retention bracket attached to an inner surface of the door that engages the housing.

A lockable enclosure includes a housing and an access door. The access door includes a hinge portion connected with a first side wall of the housing and is pivotable about the hinge portion between closed and open positions. When the access door is in the closed position, the hinge portion of the access door is slideable for sliding movement of the access door between a latching position in which a first latch portion of the access door engages a corresponding second latch portion of the housing to secure the access door in the closed position, and a release position in which the first interlock portion disengages from the second interlock portion to permit pivoting movement of the access door from the closed position to the open position. The access door further comprises at least one locking feature configured to secure the closed access door in the latching position.

A door for closing a chamber opening in a chamber wall of a vacuum chamber in relation to a surrounding space, in which the vacuum chamber is located, includes a door housing arranged, a closing member arranged in the surrounding space, and a rod, to which the closing member is connected. A first movement of the rod, through which the closing member is displaced from an open position into an intermediate position, occurs as a displacement of the rod in a longitudinal axis direction, and a second movement of the rod subsequent thereto is a displacement at an angle to the longitudinal axis or a pivoting about a pivot axis which is perpendicular to the longitudinal axis from the intermediate position into a closed position. The rod is moveably mounted via the bearing elements, that are arranged in an inner space of the door housing that is sealed with respect to the surrounding space or is connected to the surrounding space via a passage, with a filter, extending through a housing wall of the door housing. The rod is guided out of the inner space in a sealed manner.

Enclosures for an electrical apparatus include a housing comprising a back and first and second spaced apart sidewalls extending outwardly from the back and providing an interior space and a door pivotably attached to the housing, the door having a primary body with a bottom having a bottom flange and first and second laterally spaced apart side flanges. The bottom flange and the side flanges have a folded inwardly extending edge joining first and second parallel wall segments that are orthogonal to the primary body of the door. The enclosure can also include at least one slot extending through the first and second parallel wall segments of the bottom flange and/or a retention bracket attached to an inner surface of the door that engages the housing.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A cattle squeeze chute door opening assembly includes a cattle squeeze chute including a lateral wall that has an open end for having an animal extending therethrough. A door frame is attached to the cattle squeeze chute adjacent to the open end. The door frame includes a door support post spaced from the lateral wall. A space between the lateral wall and the door support post defines an access portal. The door frame including an upper frame member and a lower frame member. A gate is pivotally couple to door support post and is positionable in an open position or in a closed position. The gate has a lower edge positioned adjacent to the lower frame member. A foot actuator is mounted on the door frame. The gate is lifted upwardly and moved from a closed position to an open position when the foot actuator is actuated.

A cattle squeeze chute door opening assembly includes a cattle squeeze chute including a lateral wall that has an open end for having an animal extending therethrough. A door frame is attached to the cattle squeeze chute adjacent to the open end. The door frame includes a door support post spaced from the lateral wall. A space between the lateral wall and the door support post defines an access portal. The door frame including an upper frame member and a lower frame member. A gate is pivotally couple to door support post and is positionable in an open position or in a closed position. The gate has a lower edge positioned adjacent to the lower frame member. A foot actuator is mounted on the door frame. The gate is lifted upwardly and moved from a closed position to an open position when the foot actuator is actuated.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A shower door hinge mechanism (201) for a half-height shower door, operable to lift the shower door (203) to remove any contact between the bottom seal element (209) and the shower floor area (203). The hinge mechanism (201) comprises first and second co-operable hinge parts (204, 205) mountable to a shower door (203), and a manually-operable element (206) engageable with at least one of the first and second parts (204, 205) such that operating the manually-operable element (206) causes one of the first and second parts (204, 205) to be moved into a raised position relative to the other. Shower door apparatus (202) comprising the hinge mechanism (201), and a shower door installation (301) comprising the shower door apparatus (202). A method of enabling a shower door (203) to be lifted to enable rotation of the shower door (203) free of contact with the shower area floor.
