    Abstract: In an incubator according to the present invention, physical condition of a newborn is less likely to get out of order though a hand insertion window can easily be opened by operation with, for example, an elbow instead of a hand. A latch in a latch mechanism has a spiral face that extends to at least part of the periphery of a rotation shaft that extends along a side of a newborn chamber. A releasing member in the latch mechanism presses the spiral face of the latch by movement along the side of the newborn chamber and rotates the latch from a holding position to a releasing position for a hand insertion door. In addition, even if the latch in the latch mechanism rotates about the rotation shaft between the holding and releasing positions for the hand insertion door, the releasing member does not rotate.

    Abstract: A latching mechanism for a carrying case includes a latch body pivotally attached to a top cover of the case, a trigger pivotally attached to the latch body, and an actuator that pivots about the same axis as the trigger. The trigger is pivotable between a latching position for keeping the latch body closed, and a release position to allow the case to be opened. The actuator is pivotable toward and away from a nominal actuator position in which a panel of the actuator assumes a predetermined alignment with the latch body. A torsion spring biases the trigger toward the latching position, and through trigger/actuator contact biases the actuator into the nominal position. The trigger can move toward the release position while the actuator is held in the nominal position, to maintain the selected alignment for a more natural, intuitive latching mechanism closure.

  • Patent number: 7019233
    Abstract: The invention relates to a closing device consisting of a grip housing (10) containing a pivotably mounted grip flap (12). Said grip flap (12) is loaded by means of a restoring force (38) in the direction of its neutral position (12.1), against which force the manual actuation of the grip flap (12) must be carried out. Furthermore, an electrical switch (20) is associated with the grip housing (10), said switch comprising a spring-loaded (28) contact actuator (24). In order to provide a compact, cost-effective closing device, the restoring force (38) of the grip flap (12) can be directly generated by the spring-loading (28) of the contact actuator (24) of the electrical switch (20). In this way, separate springs are not required for the grip flap (12).

  • Patent number: 6895789
    Abstract: This lockable latch with catch for use with briefcase type fireproof safes allows the user to carry the safe by its handle (briefcase style) without the lid being locked to the body. It has both a latch and a catch that can pivot or move away from their engagement positions in a plane parallel to, and within, the body of the safe. A release button pivots the latch away from its engagement position and thereby unlatches the latch. Alternatively, a locking member can be interposed so as to prevent the latch from pivoting away from its position of engagement with the catch when the safe is locked. When the locking member is engaged and the latch is thereby locked into engagement position, the ability of the catch to temporarily pivot or move out of the way of the latch still allows the safe lid to snap shut.

  • Patent number: 4576541
    Abstract: A safety latch for a cargo platform of the type particularly adapted to be mounted on the rear of a truck's cargo body. The cargo platform is pivotally mounted along its front edge to a combined elevating/storing mechanism which is of a chain and compounding sprocket type. In this type mechanism, the chain is taut as it holds the cargo platform in horizontal position when it functions as an elevator, and the chain is taut as it is compounded when it is desired to open and close the cargo platform between vertical storage and horizontal elevator positions. The safety latch cooperates with the cargo body, the chain, and the platform to insure that the platform is latched to the cargo body in its storage position when the chain is slack, i.e., not taut. The chain is always taut when the cargo platform is in the horizontal position and used as an elevator, as well as when the cargo platform is being swung between its elevator position and its vertical position.
