1. Field of the Invention
The present invention relates generally to board games and, more specifically, to a mathematically-based game comprising a game board having four parallel rows of eight depressions for retaining game pieces such as marbles. Game pieces are arranged by each player in the depressions which are disposed within their area of play. The players then sequentially manipulate the game pieces around the game board according to mathematical calculations with the objective of eliminating all of the opponent's game pieces.
The present invention requires the user to apply addition, subtraction, thinking and reasoning thereby promoting the concentration, creativity and problem-solving abilities of the players. Furthermore, the attributes of the present invention can prove useful as a learning and a therapeutic tool for children with attention deficit disorder or learning disabilities, senior citizens, people suffering from depression and other like conditions.

A modular arrangement for supporting any one of a wide variety of sizes of reading and other materials at a freely selectable location in relation to any selected one of a wide variety of local environments, such as chairs, sofas, tables and the like is disclosed and includes an expansible reading material holding assembly along with a plurality of support mechanisms each accepted for attachment to a different class of local environment and an arrangement for coupling the holding assembly to a select one of the support mechanisms to provide limited manual adjustability of the elevation of the holding assembly relative to the selected support mechanism as well as a limited amount of manual adjustability of the holding assembly, from vertical to horizontal, as may be preferenced by the various users. In the horizontal attitude the holding assembly functions as a table. The coupling means may include an articulated arm comprising a pair of arm members journaled together at respective first ends for unrestricted angular movement in a generally horizontal plane with one of the arms having its second end pivotably attached to the support mechanism and the other of the arms having its second end pivotably supporting the material holding assembly. The material holding assembly may include lateral extension portions and telescopic risers movable in generally orthogonal directions to expand and contract the reading material support area.
The present device is an improved table for attachment to the frame of a chair. The improved table comprises, in general, a table top including a first table top half and a second table top half; cooperative holding devices for holding the table halves together to establish a unitary condition of the table top; a first crank for rotatably supporting the first table top half for rotation about a first substantially vertical axis; a first mounting tube for rotatably supporting the first crank for rotation about a second substantially vertical axis offset from the first vertical axis, a first bracket for attaching the first mounting tube to the frame of the chair; a second crank for rotatably supporting the second table top half for rotation about a third substantially vertical axis; a second mounting tube for rotatably supporting the second crank for rotation about a fourth substantially vertical axis offset horizontally from the third vertical axis, and a second bracket for attaching the second mounting tube to the frame of the chair. The dimensions of the components of the table and the distances between certain pivot axes can be selected so that parallel movement of the table top can be accomplished. However, if the dimensions of the chair are such that will not permit the above mentioned dimensions to be selected, under certain conditions the table top may be moved from a forward most position to a rearward most parallel position by skewing the table top as it is moved.
An assembly for mounting a table, tray or other removable component to a chair to support a laptop computer or other appliance includes a socket that can be permanently mounted in the chair arm and a bracket or mounting assembly that can be mounted on the bottom of the removable component. The socket includes a sleeve with a collar mounted on the top of the sleeve. The collar surrounds the area around a hole in the chair arm through which the socket sleeve extends. The sleeve is attached to an internal frame member. A spring biased plug shifts within a cavity in the sleeve. A rigid pin located on the bottom of the removable component is inserted through a central opening in the collar into the cavity, forcing the plug into the sleeve. The table is firmly supported by the socket, but it is free to rotate in a horizontal plane.
A tray 5 is supported on a chair arm, bed-rail or other support by a pair of adjustable bent arms 1 and has one or a pair of detachable telescopic legs 6 mounted in rear sockets 4. One or more straps 11 with weighted ends may assist retention or can be used to hold a book on the tray.
A device for supporting a book comprises a book support in the form of a board 2 with a shelf 4 and a clip 3, a mounting plate 5 and an extensible arm 6. The extensible arm is hinged to the book support by a bushing which enables the book support to be adjusted to the convenience of the user. When in use the plate 5 may be mounted on a wall beside a bed or chair and an open book can be placed on the board with the bottom of the book resting on the shelf and the top of the book held in clip 3. The device may also be used for writing as well as reading. It can be folded away when unused by contracting the arm 6.
While these chair/desk combinations may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
The present invention discloses a mathematically-based game comprising a game board having four parallel rows of eight depressions for retaining game pieces such as marbles. Game pieces are arranged by each player in the depressions which are disposed within their area of play.

Another object of the present invention is to provide a board game wherein each player has the two rows nearest them designated as their area of play.
Yet another object of the present invention is to provide a board game wherein each player initially has two game pieces residing in each depression in their area of play.
Still yet another object of the present invention is to provide a board game wherein play is initiated by each player rearranging their 32 game pieces within the depressions located in their play area according to their choosing.
Another object of the present invention is to provide a board game wherein the players use addition, subtraction, thinking and reasoning to calculate the movement of the game pieces into the play area of the opponent with the objective to eliminate all of the opponents game pieces.
Another object of the present invention is to provide a chair/desk combination that is simple and easy to use.
Yet another object of the present invention is to provide a chair/desk combination that is inexpensive to manufacture and operate.
