Description

[Detailed description of the invention] (Field of industrial application) This invention is an improvement of game boards such as portable shogi boards and Go boards that can be folded in half to make it compact or opened to use as a single board. Regarding.

(Prior art) Conventionally, a half-sized body was connected by a hinge made by wrapping the inner edges of a pair of small pieces around a shaft, so that it could simply be folded in half, that is, in an open state (a state that can be used for play). Portable game boards such as shogi boards and Go boards that use hinges without a mechanism for maintaining them are known.

(Problems to be solved by the invention) The portable shogi board mentioned in the above conventional technology,
Game boards such as Go boards do not have a mechanism to keep the hinges open, so if you are traveling and are playing Shogi, Go, etc. with the small board open, you may accidentally turn it upside down. Pieces on the board fold into the state,
There were undesirable defects such as disrupting the arrangement of stones, etc.

The object of the present invention is to provide a new game board that eliminates the above-mentioned defects.

(Means for Solving the Problems) In order to achieve the above object, the game board according to the present invention has a pair of small plates 1, 1' which are superimposed so that the tips of the small plates 1, 1' are The legs 3 are constructed by mutually bearing the shafts 2, and each of the small plates 1,
Rod shaft parts 4, 4' are integrally provided on the side edge of the proximal end of the leg part 1' and extend in opposite outward directions on a straight line perpendicular to the shaft metal 2 when the leg part 3 is in the closed state. The obtained hinge bodies 7, 7' and a pair of tubular bodies each having a shaft hole 8 whose inner width and depth are slightly smaller than those of the rod shaft parts 4, 4', and having attachment parts 6, 6' on the side surfaces. bearing member 5,
5' and a pair of half-sized bodies 9, 9' which form a board for games such as a shogi board when placed side by side,
Bearing members 5, 5' are fixed to the back sides of both ends of the inner sides of these half-sized bodies 9, 9' in a position on a line perpendicular to the inner sides, and these bearing members 5 , 5' has a hinge main body 7 in the shaft hole 8,
7' is fitted, and in this fitted state, the center of the shaft metal 2 of the hinge main body 7, 7' is located directly below the abutment line of the inner side, and the hinge main body 7, 7' is inserted. The leg portions 3 of the rods 4, 7' are raised along the vertical plane including the butt line, and each state of the raised shape is controlled by the force between the outer surface of the rod shaft portions 4, 4' and the square groove-shaped shaft hole 8. It was intended to be maintained through close contact.

(Embodiment) In the illustrated embodiment, the leg portion 3 is constructed by overlapping a pair of small plates 1, 1' and mutually bearing the tips of these small plates 1, 1' by a shaft metal 2. On the proximal side edge of each of the small plates 1, 1', there is a rod shaft with an elliptical cross section extending in the opposite outward direction on a straight line orthogonal to the shaft metal 2 when the legs 3 are in the closed state. The parts 4 and 4' are integrally provided to form the hinge main bodies 7 and 7', and separately there is a square groove-shaped shaft hole 8 whose inner width and depth are slightly smaller than the above-mentioned ellipse. A pair of inverted plate-shaped half-sized bodies 9, 9 which form a shogi board when the tubular bearing members 5, 5' having screw attachment parts 6, 6' are arranged side by side separately. ', respectively, and the two sides of the bearing members 5, 5' are located on a line perpendicular to the inner sides on the back side of both ends of the inner sides of the half-sized bodies 9, 9'. At the same time, the rod shaft portions 4, 4' of the hinge bodies 7, 7' are fitted into the square groove-shaped shaft holes 8 of the respective pairs of bearing members 5, 5'. The center of the shaft metal 2 of the hinge main body 7, 7' is located directly below the abutment line of the inner side, and the hinge main body 7,
The leg portion 3 of 7' can be raised along the vertical plane including the butt line, and each state of the raised shape can be compared to the rod shaft portions 4, 4'.
The outer surface of the shaft hole 8 and the square groove-shaped shaft hole 8 are held together by force. In addition, numeral 11 in the figure indicates a retaining portion.

(Function) When the leg part 3 is in the upright state, the shaft metal is oriented parallel to the abutment line, allowing the opening and closing of the leg part 3, and when the leg part 3 is in the lying state, the shaft metal 2 is oriented parallel to the abutment line. The legs are oriented perpendicularly, making it impossible to open and close the legs.

(Effects of the invention) Since the game board according to the invention has the above-mentioned configuration, when the legs 3 are in the folded state, there is no possibility that the board will accidentally break into a ``F'' shape during play. It has the excellent effect of completely achieving the intended purpose.
