Abstract:
1. A display device comprising: an elongate track extending from a back end to a front end; a pusher carried on the track for reciprocal sliding movement between rearward and forward positions; a first spring biasing the pusher forward toward the front end of the elongate track; and a second spring configured to be nondestructively disengageable with the back end of the elongate track in first and second conditions, wherein when the second spring is engaged with the back end of the elongate track in the first condition, the second spring biases the pusher rearward toward the back end of the elongate track simultaneous to the first spring biasing the pusher forward toward the front end of the elongate track so that the pusher is being biased forward by a first net forward force and when the second spring is disengaged from the back end of the elongate track in the second condition, the second spring does not bias the pusher rearward or forward and the first spring continues to bias the pusher forward toward the front end of the elongate track so that the pusher is being biased forward by a second net forward force that is greater than the first net forward force.
