Certain embodiments of the invention include an apparatus for creating a line. Certain embodiments of an apparatus include two or more reels having an extendable and retractable cord. Pulling the two or more reels apart allows for the creation of a line of various sizes. In certain embodiments, the two reels share a single cord. In certain embodiments, a first reel has a first cord with a first attachment end that joins with another attachment end. Certain embodiments include a reel with a magnet, allowing attachment to a magnetic surface. Certain embodiments of the invention include a system for creating a line. In certain embodiments, the system includes an apparatus, and a pin having a magnet. Certain embodiments of the pin help to change the direction of the cord.

Processes for dividing the arc of an angle and its angle into n number of equal parts. The same processes apply to dividing the arc of a wave of any amplitude into n number of equal lengths. The number of equal divisions to be derived may be either an even number or an odd number. The number of degrees in the arc of a circle or the angle of the circle, or in the arc of a wave or its amplitude, need be known.

A graphic alignment tool and a method of using the same are disclosed. The graphic alignment provides for a placement of a graphic on a substrate. The graphic alignment tool includes a T-shaped center bar having a base vertically disposed and a collar plate laterally disposed at a top end of the base. A width bar is dimensioned to laterally extend across a width of the substrate. A rod is configured to be received in each of the slot and the alignment slot to slidably retain the width bar in a squared orientation relative the T-shaped center bar. A logo grid may also be provided for alignment of a graphic on a chest area of the substrate. The logo grid may be slidably retained with the T-shaped center bar via a rod and a grid slot defined in the logo grid.

The present invention provides for a wall mountable system for automated drawing of an image upon a wall which includes a horizontal mounting track for mounting on a wall, a robot having a y-track rigidly mounted it where the robot and the mounted y-track travel along the horizontal track. An end effector, which includes a pen holding mechanism holding a pen, is in electrical communication with the robot and travels along the y-track of the robot. The present invention provides a system and device that can attach to a wall or vertical surface in a damage-free manner and draw fast any complexity or style image of custom size in both the horizontal (X) and vertical (Y) directions, that is easy to remove and transport and require small floor space to operate.

There is provided to a tilt board (1, 51, 61, 101) comprising an activity surface (3) supported by a base (5). The base comprises a front wall (7) and a rear wall (9) that extends downwardly from the activity surface by a greater distance than the front wall. The activity surface (3) comprises an activity surface surround (15) defining an aperture (17) therein and a removable activity surface insert (19) dimensioned for reception in the aperture. A plurality of interchangeable activity surface inserts (19) may be provided. The activity surface inserts (19) are also tilt adjustable relative to the remainder of the tilt board. The tilt board (1, 51, 61, 101) is provided with a circumferential flange so that the tilt board may be inserted into an aperture of a larger work surface such as a table if desired. The tilt board can be used for a range of activities, can lie flat in a larger work surface if desired, and the tilt angle can be adjusted to several angles which is highly advantageous.

A plotter includes a mounting portion, a first movement mechanism, a second movement mechanism, a processor, and a memory. The mounting portion is configured to mount with a pen containing a liquid. The first movement mechanism is configured to relatively move the mounting portion and a workpiece in a movement direction. The second movement mechanism configured to relatively move the mounting portion and the workpiece in a direction intersecting the movement direction. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring plot data, acquiring information relating to a remaining amount of the liquid of the pen, setting a relative movement speed of the mounting portion and the workpiece, and controlling the first movement mechanism and the second movement mechanism at the set movement speed, and performing drawing on the workpiece.

A line drawing tool includes a body; a reel that is rotatably provided in the body and that includes flanges on two ends of a thread winding shaft; a thread that is wound around the thread winding shaft and that is drawn out to outside of the body with powder that is enclosed in the body being adhered to the thread; and a clearance that is formed between the flanges of the reel and the body, the clearance being provided for allowing the powder that accumulates between the body and the flanges to escape.
