BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand of a table-top type full-automatic mahjong table which can be seated on a chair or the like to perform full-automatic mahjong table.

[0002]

2. Description of the Related Art A stand-up type full-automatic mahjong table is widely known, but such a stand-up type full-automatic mahjong table is suitable for being installed in a certain place. It cannot be used in Japanese rooms such as inns and hotels according to the customer's request. Therefore, the fully automatic mahjong table is configured so that the main body part of the fully automatic mahjong table is placed on a movable leg stand that can support the mahjong table at a height that can be used as a table and can be transported during use. Has been developed.

[0003]

However, according to such a table-top type full-automatic mahjong table, the full-automatic mah-jong table is used on the base, that is, a wide rectangular top board is used. Since it is placed and fixed horizontally, it requires not only a wide passage to carry it from a storage location to a room such as a Japanese-style room, but it is fully automatic especially at entrances narrower than the passage. It was inconvenient to handle the mahjong table unless it was lifted and tilted so that it could not be taken in and out. Further, there is a problem that even when not in use, a large storage area is required and only a small number can be stored. It is an object of the present invention to provide a stand for a table-top type full-automatic mahjong table that can completely solve such problems.

[0004]

In order to achieve the above object, the base of the table-top type fully automatic mahjong table of the present invention has a plane rectangular frame shape in which casters are attached to the lower ends of the four-sided short legs. The base end portion of the first support frame body extending toward the other side frame portion is pivotally attached to one side frame portion of the base body of the base body so as to be capable of undulating, and the fully automatic mahjong table is attached to the tip end of the first support frame body. Connected to the outer bottom of
An attachment piece to be fixed is rotatably attached, and a base end portion of the second support frame body is rotatably pivotally attached to the other side frame portion of the leg base main body so that the above-mentioned 1 A mounting piece to be connected and fixed to the outside of the outer bottom surface of the fully automatic mahjong table with a certain distance from the mounting piece of the support frame is rotatably attached, and further, a lever member is attached to one side frame portion of the pedestal body. It has a structure in which a base end portion is rotatably attached, and a locking projection protruding from the lower surface of the first support frame is provided on the base end portion.

In the footrest, as described in claim 2, an engaging hole member is provided at an appropriate position of the second support frame body, while the base member of the lever member is provided with a hoisting and swinging member. It is desirable to provide a lock mechanism for holding the fully automatic mahjong table in an upright state by pivotally attaching the base end of the engagement rod body whose distal end engages and disengages with the engagement hole member by movement.

[0006]

In the outer bottom surface of the fully automatic mahjong table placed on the main body of the pedestal, the first and second support frames are provided from the central portion to the outer bottom surface portion from the other side portion and the outer end portion of the other side portion. A table-top fully automatic mahjong table is constructed by connecting and fixing a mounting piece that is rotatably attached to the tip of the body by screwing or the like. From this state, when the lever member rotatably attached to the one-side frame portion of the pedestal base is depressed and pushed down while the one-side edge portion of the fully automatic mahjong table is lifted with both hands, the lever member is pushed down. The locking protrusion protruding from the base end of the first support frame moves upward and the first support frame rotates in the upright direction.

As the first supporting frame stands up, the fully automatic mahjong table is lifted in an oblique state with the mounting piece of the second supporting frame as a fulcrum, and the second supporting frame also gradually stands up following it. . When the lever member is further depressed, the first and second support frames supporting the outer bottom surface of the fully-automatic mahjong table stand up to the maximum and one side of the fully-automatic mahjong table faces upward, The side surface is lifted up to the standing state, and the other side surface facing downward is received on the leg stand and held in the standing state.

In this state, storage and transportation are carried out. However, if the fully automatic mahjong table is fixed and held in an upright state by a lock mechanism on the pedestal, the transportation can be carried out safely. Also, when in use, the fully automatic mahjong table is tilted in the opposite direction to bring it into a horizontal state, and its outer bottom surface is placed on and received by the pedestal. At this time, the fully automatic mahjong table is tilted so that it gradually becomes horizontal while controlling the sharp tilt of the table by stepping on the lever member. When the fully-automatic mahjong table is supported horizontally on the platform, the table top surface becomes the height of the table, and the mahjong tiles are accommodated and arranged in the fully-automatic mahjong table to play the game.
