Description

  The present invention relates to an assembly-type learning desk that can adjust the top board according to the growth of school children.

  There is a desk that allows the top and bottom to be moved up and down because the growth desk grows quickly and quickly even if it is purchased according to the body shape, as a learning desk for growing school children (Patent Document 1).

  However, since the support plate is attached to the top plate, the top plate increases in weight, and the adjustment work becomes large, and it is difficult to perform the adjustment work alone.

  Therefore, a learning desk that can be easily assembled and adjusted by one person has been desired.

Japanese Patent No. 3474731

  The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. That is, the object is to allow the top plate or the like to be easily moved up and down, and to allow the height to be adjusted by one person.

  By doing in this way, the height of the top plate according to the growth of the schoolchild can be easily adjusted.

  In order to solve such problems, the present invention comprises a top plate, a side plate and a reinforcing plate, and a plurality of top plate mounting holes are arranged in the vertical direction of the side plate, and the rear top plate mounting hole A reinforcing plate mounting hole is provided in the rear portion in parallel with the top plate mounting hole so that the height of the top plate can be adjusted.

  Also, in order to be able to use the top plate tilted, a top plate diagonal position mounting hole is provided in front of the rear top plate mounting hole so that it is equidistant from the front top plate mounting hole and the rear top plate mounting hole. Yes.

  Since this invention is such a structure, the height of a top plate can be adjusted only by fixing a top plate, a side plate, and a reinforcement board.

  In addition, the reinforcing plate can be used as a footrest or a shelf if the reinforcing plate is provided vertically, and the lower reinforcing plate is L-shaped in cross section.

  In this way, the present invention does not simply change the position of the top plate, but can change the position of the reinforcing plate, so the strength increases due to the synergistic effect of the top plate and the reinforcing plate, and it can be used with confidence. be able to.

  In addition, the top plate is not only located in parallel, but also can be moved in an oblique direction, which is convenient when drawing a picture.

  An embodiment will be described with reference to the drawings. In FIG. 1, 1 is a top plate, 2 is a pair of left and right side plates, 3 is a reinforcing plate, and 4 is a shelf.

  Front and rear fixing holes 11 and 12 in which demon nuts are embedded are provided on the left and right sides of the top plate 1. In addition, an oblique position fixing hole 13 in which a demon nut is embedded is provided in the front part of the rear fixing hole 12.

  In the side plate 2, a plurality of top plate mounting holes 21, 22 are arranged at a fixed pitch in the vertical direction, and the reinforcing plate mounting holes 23 are arranged in parallel with the top plate mounting holes at the rear of the rear top plate mounting holes 22. Is provided. A plurality of top plate oblique position mounting holes in the vertical direction at positions corresponding to the oblique position fixing holes 13 when being rotated upward about the front fixing hole 11 at the front portion of the rear top plate mounting hole 22 24 are arranged at a constant pitch.

  The reinforcing plate 3 includes fixed holes 31 and 32 in which demon nuts are embedded in the vertical direction at the same interval as the interval between the reinforcing plate mounting holes 23 of the side plate 2.

  The shelf 4 is configured to have an L-shaped cross section composed of a vertical plate 4A and a horizontal plate 4B. The vertical plate 4A is provided with a fixing hole 41 in which a demon nut is embedded at a position coinciding with the reinforcing plate mounting hole 23, The plate 4B is provided with a fixing hole 42 in which a demon nut is embedded at a position coinciding with the rear top plate mounting hole 22.

  Then, the front and rear fixing holes 11 and 12 of the top plate 1 may be matched with the top plate mounting holes 21 and 22 of the side plate 2 at a height according to the height of the schoolchild and tightened with the screws 5.

  Note that when the front fixing portion 11 of the top plate 1 is screwed to an appropriate position of the front top plate mounting hole 21 to be inclined forward, the top plate oblique position mounting hole above the front fixing portion 11 is used. The top plate can be tilted forward by screwing the diagonal position fixing hole 13 of the top plate to 24.

  It is a perspective view of the present invention.   It is a side view of this invention.   It is a side view of the top plate used by this invention.   It is a side view of the reinforcement board used by this invention.   It is a side view of the shelf used by this invention.
