Abstract
A positioning device is provided which is adapted to be secured to the back edge of a picture frame or the like. The device comprises a pivotally mounted indicator arm adapted to freely hang in the vertical plane when the picture frame on which disposed is in a normal hung position. When the picture frame is horizontally level no portion of the indicator arm is visible from the picture front; when the picture is not level a portion of the indicator is visible to the picture viewer.
Claims8
In combination, an object such as a picture frame, mirror or the like for suspending substantially in the vertical plane having a normally visible front surface and an opposed, normally hidden rear surface;
- indicator means for indicating whether said object is desirably suspended relative to the horizontal plane mounted on said object rear surface;
- a suspension point mounted on said object rear surface on which said indicator means is supportably mounted;
- said suspension point comprising a pivot enabline said indicator means to freely hang in a predetermined manner in the vertical plane regardless of the disposition of said object relative to the horizontal plane while said object is suspended substantially in the vertical plane;
- said indicator means being located relative to the periphery of said object so as to be hidden from view when viewing the front surface of said object when said object is suspended in substantially the vertical plane with said object at a predetermined angular disposition relative to the horizontal plane;
- said indicator means being visible when viewing the front surface of said object while suspended in substantially the vertical plane when said object is not in said predetermined angular disposition relative to the horizontal plane.
In combination, an object such as a picture frame, mirror or the like for suspending in substantially the vertical plane having a normally visible front surface and an opposed, normally hidden rear surface;
- indicator means pivotally supportably mounted on said normally hidden rear surface for visibly indicating to a viewer of said first surface when said object is in a particular orientation relative to the horizontal plane while suspended in said substantially vertical plane;
- said indicator means being pivotally mounted on said normally hidden surface and hidden behind said normally visible surface when said object is suspended substantially in the vertical plane in said particular orientation, and being visible by projecting from behind the periphery of said normally visible surface when said object is suspended in the vertical plane and is not in said particular orientation relative to the horizontal plane.
In combination, an object such as a picture frame, mirror or the like for suspending in substantially the vertical plane and having a normally visible surface and an opposed normally hidden surface;
- indicator means supportably mounted on said normally hidden surface having a peripheral portion in registration with a peripheral portion of said object so as to be hidden from view when said normally visible surface is viewed with said object suspended in substantially the vertical plane and said object is suspended in a particular disposition relative to the horizontal plane;
- said indicator means being visible by projecting from behind a peripheral portion of said object when said normally visible surface is viewed with said object suspended in substantially the vertical plane and said object is not in said particular disposition relative to the horizontal plane;
- said indicator means assuming a substantially constant angular disposition relative to the vertical plane which is independent of said object disposition relative to the horizontal plane when said object is suspended in substantially the vertical plane.
