1. A presentation box for storing and presenting an article, the presentation box comprising:
an upper case forming a top portion of the presentation box; a lower case forming a bottom portion of the presentation box; a hinge arrangement for connecting the upper case to the lower case such that the upper case may be pivoted relative to the lower case between a closed position in which the upper case and the lower case define an enclosed volume for storing the article within the presentation box and an open position for presenting the article; a movable article mount for supporting the article to be presented in the presentation box; and an articulated linkage including a plurality of links connecting the article mount to other elements of the presentation box such that the articulated linkage moves the article mount from a stored position when the upper case is in the closed position to a presentation position that is elevated relative to the stored position when the upper case is in the open position thereby presenting the article when the upper case is moved from the closed position to the open position, the articulated linkage including a four-bar linkage and a drive link with
portions of the lower case acting as a fixed bar of the four-bar linkage with the fixed bar having a first and a second spaced apart pivot point,the movable article mount acting as a movable second bar of the four-bar linkage with the movable second bar having a first and a second spaced apart pivot point,the four-bar linkage further including a movable third bar and a movable fourth bar with both the third bar and the fourth bar having a first and a second spaced apart pivot point,the movable third bar being pivotally connected between the fixed bar and the movable second bar with the first pivot point of the third bar pivotally connected to the first pivot point of the fixed bar and the second pivot point of the third bar pivotally connected to the first pivot point of the movable second bar,the movable fourth bar being pivotally connected between the fixed bar and the movable second bar with the first pivot point of the fourth bar pivotally connected to the second pivot point of the fixed bar and the second pivot point of the fourth bar pivotally connected to the second pivot point of the movable second bar, andthe drive link having a first and a second spaced apart pivot point with the first pivot point being pivotally connected to one of the movable bars and the second pivot point being pivotally connected to other elements of the presentation box such that the drive link causes the four-bar linkage to elevate the movable article mount relative to the lower case and present the article when the upper case is moved from the closed position to the open position. |
