Abstract
A marking device or scribe for marking masonry pieces on a horizontal deck area surrounding a pool, sauna or similar below-ground construction. The device is designed for use during construction of deck areas to enable defining a border or margin a constant distance from a curved vertical edge. This marking facilitates subsequent cutting of the marked masonry pieces for removal and construction of a more aesthetic edge border. Device guide wheels follow curved vertical walls of the pool and guide a frame and attached marker that is supported on wheels on the deck. The marking device is biased against the masonry pieces to create a path line mark as the frame and guide wheels are manually move along the edge.
Claims8
A device for marking a line on horizontal surface surrounding and following a curved perimeter edge of a swimming pool, the device comprising:
- two guide wheels having a common horizontal plane and having respective vertical axes of rotation;
- a horizontal centerline passing between the guide wheels;
- two support wheels having respective horizontal rotation axes located on opposite sides of the guide wheel horizontal centerline;
- two secondary wheels having respective secondary horizontal rotation axes located on opposite sides of the guide wheel horizontal centerline;
- a rigid frame having a first end and a second end;
- the support wheels secured to the first end;
- the second end having a downwardly extending neck portion;
- the guide wheels secured to the neck portion;
- the secondary wheels secured to the frame between the guide wheels and the support wheels such that the secondary wheels and the support wheels have a common contact plane;
- a rigid handle extending generally upward from the frame to a grip configured to be grasped by a user standing on the contact plane;
- a marker extending downward from the frame, and having a horizontal marker distance dimension from the guide wheels;
- an adjustment means for altering the marker dimension over the range of three to twelve inches;
- a biasing means for biasing the marker against a horizontal surface on the contact plane;
- such that the support wheels and secondary wheels may be placed on a horizontal working surface while maintaining the guide wheels in contact with a vertical wall below the support wheels and between the support wheels and the guide wheels, while the marker is biased against the working surface.
