Abstract

An indicating mechanism is described. The mechanism is ideally suited for the indication of time but is also applicable to other indicating functions where changing information must be displayed. The mechanism is composed of a flexible belt bearing indicia and three supportive discs. As the discs are caused to rotate, the belt and any indicia on it will rotate. This rotation will be apparent to users who see or touch the indicia on the belt, thus providing an indicating function. The unique geometry of the belt gives two full circular discoidal surfaces for decoration. Typically only one of these surfaces will be visible to users as the other is disposed directly below it. This arrangement allows times within each 12 hour period in the 24 hour day cycle to be indicated uniquely while maintaining the conventional location of each AM and PM hour's representation of the clock face.

Dependent claims

A flexible belt for use as an indicator of an indicating device having a shaft mechanism which rotates about an axis during use of the device, said belt comprising:

a first discoidal side portion including a first face having a circular periphery, a circular hole in the center of the first face and a slit having two sides which extend radially across the first face from the edge of the circular hole in the center to the circular periphery of said first face;
and
a second discoidal side portion including a second face having a circular periphery, a circular hole in the center of the first face and a slit having two sides which extend radially across the second face from the edge of the circular hole in the center to the circular periphery of said second face;
and
said first side portion and said second side portion being arranged in a back-to-back relationship so that the faces thereof face in opposite directions and so that the slits thereof are positioned in registry and provide a single two-sided gap extending from the edges of the circular holes in the center of each face to the circular peripheries of the side portions;
said first and second side portions being joined to one another along each side of said two-sided gap and having means for permitting rotation of said side portions by the rotatable shaft mechanism of the indicating device such that said first and second side portions rotate in opposite directions relative to each other about an axis extending through the centers of the faces and a sector of the first side portion moves through the two-sided gap to the belt side corresponding with the face of the second side portion and a sector of the second side portion moves through the two-sided gap to the belt side corresponding with the face of the first side portion so that as the face of one side portion is viewed frontally, the face of the belt side portion being viewed disappears through the gap and the face of the opposite belt side portion appears through the gap;
and
indicia means associated with at least one of the first and second side portions for indicating the positional relationship of the first and second side portions as the side portions are rotated relative to each other as aforesaid.

In an indicating device having a shaft which is rotatable about an axis of rotation during use of the device, means for rotating the shaft about the rotation axis and an indicator associated with said shaft for movement as the shaft is rotated, the improvement comprising:

a flexible belt for use as the indicator of the device including
(a) a first discoidal side portion including a first face having a circular periphery, a circular hole in the center of the first face and a slit having two sides which extend radially across the first face from the edge of the circular hole in the center to the circular periphery of said first face and
(b) a second discoidal side portion including a second face having a circular periphery, a circular hole in the center of the second face and a slit having two sides which extend radially across the second face from the edge of the circular hole in the center to the circular periphery of said second side portion, said first side portion and said second side portion being arranged in a back-to-back relationship so that the faces thereof face in opposite directions and so that the slits thereof are positioned in registry and provide a single two-sided gap extending from the edges of the circular holes in the center of the faces to the circular peripheries of the faces, and said first and second side portions being joined to one another along each side of said two-sided gap;
means for connecting the belt to the rotatable shaft of the device for rotating said first and second side portions in opposite directions relative to each other about an axis extending through the center of and generally perpendicular to said faces so that as a sector of the first side portion moves through the two-sided gap to the belt side corresponding with the face of the second side portion a sector of the second side portion moves through the two-sided gap to the belt side corresponding with the face of the first side portion whereby as the face of one side portion is viewed frontally, the face of the belt side portion being viewed disappears through the gap, and the face of the opposite belt side portion appears through the gap;
and
indicia means associated with at least one of the first and second side portions for indicating the positional relationship of the first and second side portions as the side portions are rotated relative to each other as aforesaid.
