Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a television game machine, and particularly to a structure for adjusting the height thereof.

[Conventional technology]

Conventionally, video game machines installed in game centers and the like have had a configuration in which a game screen display device (monitor) is installed above a box placed on the floor. This type of video game machine has two types: a rubber type that allows you to play the game while sitting on a chair, and an upright type that allows you to play the game while standing. I was trying to change the height from the to the monitor.

Further, Japanese Utility Model Publication No. 61-103187 discloses a rubber-type box provided with extendable legs so that the height of the box from the floor can be adjusted. That is, four legs are slidably attached to a rubber-type box so as to protrude from the bottom thereof, and each of these legs is formed with a plurality of pin holes arranged in the height direction.
By selecting one of these multiple pin holes and passing the pin passed through the pin hole of the box into the selected pin hole, the leg can be fixed to the box with the desired protruding length from the bottom of the box. and
It is configured so that the height from the floor to the box, that is, the height from the floor to the monitor, can be adjusted.

[The problem that the idea aims to solve]

Conventionally, in order to configure the rubber type and the upright type, it was necessary to manufacture two types of boxes with different lengths at the bottom. For this reason, the number of manufactured parts and the number of managed parts have increased, causing an increase in costs. In addition, since the rubber type and upright type are not compatible, manufacturers must manufacture both types in advance, regardless of whether there is an order, in order to be able to respond to sudden orders. There was a problem that it became a burden. In addition, for the purchaser, for example, after purchasing the rubber type,
When the rubber type is no longer needed and the upright type is needed, a new upright type must be purchased, causing the problem that the previously purchased rubber type is wasted.

On the other hand, the video game machine disclosed in Japanese Utility Model Application No. 61-103187 can be configured as either a rubber type or an upright type by changing the length of the legs, but this configuration does not allow for height adjustment. The drawback is that the user must hold the box while inserting the pin into another pin hole, and the monitor installed in the box is heavy, making it impossible to adjust the height by one person.

In view of the above circumstances, the present invention aims to provide a video game machine that can be used as both a rubber type and an upright type, and can easily be changed between the rubber type and the upright type. It is something.

[Means to solve the problem]

In order to solve the above problems, the present invention includes a box provided with a game screen display device on the top surface and a female screw provided approximately in the center of the bottom surface, telescoping legs supporting the box, and the female screw. a base to which the lower end of a feed screw screwed onto the screw is rotatably attached; a handle provided at the upper end of the feed screw for rotating the feed screw to raise and lower the box; and a handle for raising and lowering the box by rotating the feed screw; and fixing means for fixing the leg portions to hold the display device in place, and the height of the display device can be changed by operating the handle.

[Effect]

According to the above configuration, when the feed screw rotatably attached to the base is rotated by rotating the handle, the bottom surface of the box rises or falls, and the height of the box from the floor changes. Furthermore, the length of the leg portions protruding from the bottom of the box changes in accordance with the vertical movement of the box, and by fixing the leg portions to the box, the height of the box is set at the adjustment position. This changes the height of the game screen display device from the floor.
