Abstract

The present disclosure provides a manual dexterity training device that addresses cognitive and motor skill decline through progressive therapeutic exercises. The device comprises an object configured to be manually moved, and a container with an open face defining side-A and side-B. A central vertical divider separates the sides and includes a protruding section with holes extending through face-A and face-B. Cover-A and cover-B are hingedly coupled to move between horizontal and vertical positions, each including holes for object passage. The device enables objects to move from side-A to side-B through aligned holes, providing graduated difficulty levels that help maintain independence and cognitive function in aging populations and individuals with neurological conditions.

at least a third hole extending through the cover-B and configured to passingly receive the object,

wherein the cover-B is coplanar to the open face of the container in the horizontal position, and

wherein at the vertical position, the third hole is aligned to the first hole of the central vertical divider;

wherein the object is stored in the side-A and readily movable to the side-B by passing through the first hole formed in the central vertical divider, the second hole formed in the cover-A and the third hole formed in the cover-B, and

wherein the cover-A and cover-B are independently positionable to create multiple skill-level paths for transferring objects between the side-A and side-B.

2 . The device of claim 1 , wherein the container comprises a circular bowl.

3 . The device of claim 1 , wherein the central vertical divider is removably positioned within the container.

4 . The device of claim 3 , wherein the central vertical divider snaps into position within the container.

5 . The device of claim 1 and further comprising:

a second object that is larger than the object; and

at least a fourth hole extending through the face-A and the face-B of the central vertical divider, the fourth hole configured to passingly receive the second object.

6 . The device of claim 5 , wherein:

the first hole defines a first-hole diameter; and

the fourth hole defines a fourth-hole diameter that is larger than the first-hole diameter.

7 . The device of claim 5 , wherein the object and the second object are different marbles.

8 . The device of claim 7 , wherein the different marbles have color-specific sizes.

9 . The device of claim 1 , wherein the second hole in the cover-A and the third hole in the cover-B are color-coded to correspond with the object.

10 . The device of claim 1 , wherein the cover-A and the cover-B are magnetically held in the horizontal position and the vertical position.

11 . The device of claim 1 , further comprising a shoulder bracket removably attachable to the central vertical divider,

wherein the shoulder bracket is configured to promote shoulder mobility.

12 . The device of claim 1 , further comprising sound dampening pads positioned within the container.

13 . The device of claim 1 , wherein the container has a diameter of approximately twelve inches.

14 . A method for training manual dexterity, comprising:

providing a manual dexterity training device comprising:

an object defining a shape and a size;

a container configured to readily and removably store the object, the container comprising an open face, a side-A, and a side-B;

a central vertical divider positioned within the container and separating the side-A from the side-B, the central vertical divider comprising a face-A, a face-B parallel to and offset from the face-A, and at least a first hole extending through the face-A and the face-B, the first hole sized to passingly receive the object;

a cover-A hingedly coupled to either the face-A of the central vertical divider or to the container, the cover-A being configured to move between a horizontal position and a vertical position, the cover-A comprising at least a second hole extending therethrough and sized to passingly receive the object; and

a cover-B hingedly coupled to either the face-B of the central vertical divider or to the container, the cover-B configured to move between a horizontal position and a vertical position, the cover-B comprising at least a third hole extending therethrough and sized to passingly receive the object;

positioning the object in the side-A of the container;

selecting a skill-level path from a plurality of available skill-level paths for moving the object from the side-A to the side-B; and

moving the object from the side-A to the side-B through the selected skill-level path.

15 . The method of claim 14 , wherein the plurality of available skill-level paths comprises:

a first skill-level path wherein the cover-A is positioned in the horizontal position, and the object is moved over the central vertical divider; and

a second skill-level path wherein the cover-A is positioned in the vertical position with the second hole aligned to the first hole, the cover-B is positioned in the horizontal position, and the object is moved through the second hole and the first hole.

16 . The method of claim 15 , wherein the first skill-level path provides a beginner difficulty level, and the second skill-level path provides an intermediate difficulty level.
