[Industrial applications]

 The present invention relates to a learning desk that can be used by children of lower grades to adults according to their physique at each stage.

[0002]

[Prior art]

 Conventionally, when children of lower grades use a learning desk that has a top plate fixed to a certain height according to the size of an adult, the chair should be raised above the height normally used by adults. At this time, since the children's feet do not touch the floor surface, to prevent this, the height of the footrest plate can be adjusted between the left side of the cabinet and the left leg of the desk, which is also placed on the right side of the desk. I set it up, put my feet on it, and used it on the floor.

Then, as the physique of the child becomes larger, the height of the chair is made lower, and accordingly, the supporting height of the footrest plate is also made lower, and the physique is sufficient so that the child does not need the footrest plate. At that time, the footboard was removed and used.

That is, even if the tabletop has a constant height, it can be used according to the physique by adjusting the heights of the chair and the footrest plate, but the presence of the cabinet makes it possible to use the seating position of the user. Is limited, the range of use of the tabletop is the same for both lower grades and adults (actual size of the tabletop), depending on the opposite side of the cabinet position. Therefore, there is a problem that the usability is poor.

[Problems to be solved by the device]

 The present invention aims to solve the above problems. In other words, the present invention can be used by children of lower grades according to their physique, and if their physique becomes larger, their seating position will change, and the top plate will have a wide range (actual range of use) according to their physique. It is an object of the present invention to provide a learning desk that can obtain the above, and is not affected by the range of use of the tabletop regardless of whether it is left-handed or right-handed.

[0006]

[Means for solving the problem]

 It can be stored under a desk and the top plate of the desk, has a movable cabinet with casters on the bottom surface, and a footrest plate supported by the legs of the cabinet and desk. A cabinet connecting hole and a plurality of foot mounting plate height adjusting holes having a predetermined pitch in the vertical direction are formed in two rows in the front and rear, while the left and right side plates of the cabinet for connecting corresponding to the cabinet connecting holes. A footrest supporting hole is formed corresponding to the through hole and the footrest height adjusting hole.

[0007]

[Action]

 According to the above means, the cabinet can be connected to either the left or right side of the inner surface of the legs of the desk according to the user's right-handedness or left-handedness, and the footrest plate can be attached to either the left or right side of the cabinet. In addition, the cabinet does not move by being connected to the legs of the desk, and it supports the footrest plate stably and can be used for children of lower grades. Also, since the cabinet has casters on the bottom surface and is movable, it can be used outside the desk by disconnecting the legs and removing the foot plate, so that it can be used at the center between the left and right legs of the desk. You can sit down and use the top surface of the top plate in a comfortable position and widely.
