Latches and associated devices, including galley carts, are disclosed. An aircraft galley cart in accordance with an embodiment of the invention can include a body having a payload compartment and sized to move along an aircraft seat aisle. A door can be attached to the body to be movable between an open position and a closed position. A latch can be coupled to at least one of the door and the body, and at least a portion of the latch can be movable between a secured position and an unsecured position. When the latch is in the secured position, the door can be secured with the latch releasably coupling the door and the body together at fewer than three locations. When the latch is in the unsecured position, the door can be movable from the closed position to the open position.

The invention claimed is: 1. An aircraft galley cart, comprising: a body having a payload compartment, the body being sized to move along an aircraft seat aisle; a plurality of wheels attached to the body; a generally rigid door pivotably attached to the body and movable between an open position and a closed position; and a latch having: a receptacle unit attached to one of the body and the door, the receptacle unit having an aperture with a chamfered entrance; a guide coupled to the other of the body and the door, the guide having a first channel and a second channel generally parallel to the first channel, the guide further having a first surface and a second surface facing toward the first surface; a slider with a grip portion configured to be manipulated by a user, the slider being carried by the guide and movable relative to the guide between a secured position and an unsecured position, wherein the aperture of the receptacle is positioned between the first and second surfaces of the guide when the slider is in the secured position; a first member carried by the slider, received in the first channel of the guide and having a chamfered end; a second member carried by the slider and received in the second channel of the guide, the first member (a) being received in the aperture of the receptacle unit and (b) extending entirely through the aperture and into an opening in the second surface of the guide when the slider is in the secured position to releasably secure the door relative to the body at only a single location, the first member being external to the aperture when the slider is in the unsecured position, the first member being the only one of the first and second members to be received by the receptacle unit; and a forcing device positioned to force the slider toward the secured position. 2. The galley cart of claim 1 wherein the door includes a frame portion and a panel portion carried by the frame portion, the frame portion being attached to the panel portion to resist bending of the panel portion. 3. The galley cart of claim 1 wherein the latch is the only latch releasably securing the door to the body of the galley cart. 4. The galley cart of claim 1 wherein door is pivotable relative to the body about a pivot axis, and wherein the door has a first edge generally transverse to the pivot axis and a second edge spaced apart from the first edge and generally transverse to the pivot axis, and wherein the latch engages the body at only a single location between the first and second edges, the single location extending over less than the distance between the first and second edges. 5. The galley cart of claim 1 wherein the latch further includes a detent mechanism positioned to provide audible, tactile or both audible and tactile feedback when the latch moves from the unsecured position to the secured position. 6. The galley cart of claim 1 wherein the payload compartment includes shelves positioned to carry food items. 7. A method for using an aircraft galley cart, comprising: moving a galley cart along an aircraft seat aisle; preparing the galley cart for access by moving a door latch of the galley cart from a secured position to an unsecured position; opening the door of the galley cart after moving the door latch to the unsecured position; accessing a body of the galley cart through the open door; closing the door of the galley cart; and at least restricting access to the galley cart by moving the door latch from the unsecured position to the secured position, with the door latch releasably coupling the door to the body of the galley cart at only a single location, wherein moving the door latch includes: contacting a slider portion of the latch, the slider portion being operatively coupled to the door; moving the slider portion of the latch relative to a guide portion of the latch against a force provided by a forcing device that forces the latch torward the secured position so that a first member of the slider portion slides along a first guide path of the guide portion and a second member of the slider portion slides along a second guide path of the guide portion, the first and second guide paths being generally parallel to each other; allowing the forcing device to drive the first member along the first guide path into and through an aperture of a receptacle unit carried by the body of the galley cart, and into an opening in the guide portion of the latch, while the receptacle is positioned between the first guide path and the opening, without having the second member engage with or disengage from the receptacle unit. 8. The method of claim 7 wherein door is pivotable relative to the body about a pivot axis, and wherein the door has a first edge generally transverse to the pivot axis and a second edge spaced apart from the first edge and generally transverse to the pivot axis, and wherein moving the door latch from the unsecured position to the secured position includes releasably securing the door to the body of the galley cart at only a single location between the first and second edges, the single location extending over less than a distance between the first and second edges. 9. The method of claim 7, further comprising receiving audible, tactile or both audible and tactile feedback when the latch moves from the unsecured position to the secured position.
