Abstract
A vacuum cleaner and a method for constructing a vacuum cleaner is disclosed. The vacuum cleaner utilizes interchangeable detent bars having different numbers of detents thereon to selectively determine the number of height adjustment selections the vacuum cleaner will have. The vacuum cleaner includes a chassis, a detent bar attached to the chassis, a cam member slidably mounted to the chassis and a wheel retainer with laterally spaced wheels thereon. The wheel retainer is pivotally mounted to chassis such that the wheels may pivot toward and away from the chassis. The wheel retainer has a cam follower surface thereon which operatively cooperates with a cam surface on the cam member to raise and lower the wheels relative to the chassis as the cam member is moved. The cam member has a finger selectively engageable with individual detents on the detent bar to selectively laterally position the cam member relative to the chassis and thereby selectively establish the height of the chassis from a floor surface. The number of selectable height positions that the vacuum cleaner has is determined by the number of detents of the particular detent bar chosen to be installed on the chassis.
