  However, in the above-mentioned conventional writing board, since the width of the upper surface of the board 21 and the width of the upper surface of the bag body 23 provided on the entire back surface of the board 21 are substantially equal, the upper surface of the board 21 cannot be widened. When used, there was a problem that it might be narrow.

  In addition, the above-mentioned conventional writing board has a grip 24 to be gripped by hand at the upper end on the back side of the board 21, so that it is easy to carry, but it remains in its original shape when carried. However, it cannot be made compact, and has a problem that it is inconvenient to carry.

  Further, even in the above-described conventional portable table, the upper surface of the table plate 31 is wide because the width of the upper surface of the table plate 31 is substantially equal to the width of the upper surface of the cushion material 32 provided on the bottom surface of the table plate 31. Inevitably, there was a problem that it might become narrow at the time of use.

  In the conventional portable table, the portable table can be folded to be compact and portable. As shown in FIG. 20, this can be made compact by folding, but when trying to fold, even when physically considered, the cushion material 32 is in a more unclean state than the table plate 31. It is difficult to say that it is in an excellent design state because it protrudes, and as a portable table considering the compactness for portable purposes, it is generally only carried in a very clunky state as a portable item. The degree of completion is very low. Therefore, the structure of the portable table has a problem that it is not compact for general portability and is very inconvenient to carry.

  Therefore, the present invention solves the above-mentioned conventional problems, the upper surface of the top plate as a board or table plate is made wider than the upper surface of the cushion material, so that it does not become too narrow during use, Furthermore, even if the cushion material is a granular material such as a bead cushion, the present invention has been made for the purpose of providing a knee-mounting portable desk that can be made compact and easy to carry.

  The knee-mounting portable desk of the present invention is such that a top plate 2 that is wider than the upper surface of the cushion material 1 and can be bent is attached to the upper surface of the cushion material 1 that can be placed on the knee.

  In the knee-mounting portable desk of the present invention, a fold 5 is formed on the top plate 2 so that the fold 5 can be in a mountain fold state.

  Furthermore, the knee-mounting portable desk of the present invention is configured such that a wide portion of the top plate 2 can be bent so as to contact or approach the side surface and the lower surface of the cushion material 1.

  In the knee-mounting portable desk of the present invention, a plurality of the cushion materials 1 are attached to the top plate 2 with an appropriate interval S, and are positioned between the plurality of cushion materials 1. Thus, the fold 5 is formed in the top plate 2, and when the top plate 2 is folded by the fold 5, the plurality of cushion materials 1 are in contact with each other or approach each other.

  The knee-mounting portable desk according to the present invention is configured as described above, and the upper surface of the top plate as a board or table plate is made wider than the upper surface of the cushion material, so that it does not become too narrow during use. It became a thing.

  The cushion material 1 can be deformed into an arbitrary shape in a state in which a bag 4 is filled with a granular material 3 such as a bead cushion. In the illustrated case, the bag body 4 is open at the portion that contacts the back side of the top plate 2, and this open portion is closed by attaching the top plate 2. The portion that abuts on may be closed from the beginning, and the top plate 2 can be attached to the closed surface. One cushion material 1 can be attached to the top plate 2, or a plurality of cushion materials 1 can be attached to the top plate 2 at an appropriate interval S. The granular material 3 is not limited to bead cushions, and woody materials such as cypress, sawdust, etc. may be used.

  The top plate 2 is made of cardboard, a synthetic resin plate, or the like having sufficient strength to be used as a desk plate or a table plate. In the case shown in FIGS. 1 to 13, the top plate 2 extends over the upper surfaces of the two cushion materials 1. In addition, they are wider than their upper surfaces so that the space S is spaced apart and the surroundings protrude. Further, a crease 5 is formed in a portion where the interval S of the top plate 2 is spaced or protruded, and the fold 5 can be bent.

  The top plate 2 shown in FIGS. 1 to 4 forms two folds 5 so as to be positioned between the two cushion materials 1. Then, these folds 5 are made into a mountain fold state, and a wide part of the top plate 2, that is, a part with a gap S or a part that protrudes is bent so as to contact or approach the side surface of the cushion material 1. Then, as shown in FIGS. 3 and 4, the two cushion materials 1 are brought into contact with each other and overlapped with each other, so that a compact one is obtained. In addition, what is necessary is just to make the said space | interval S into a dimension equal to the thickness when the two cushion materials 1 are overlap | superposed in order to make the two cushion materials 1 overlap in a natural state. Further, the interval S can be made larger or smaller than the above dimensions depending on how the granular material 4 is filled in the bag body 3.

  Further, the top plate 2 is sandwiched by a clip 6 so that the bendable portion is prevented from bending. That is, the clip 6 is sandwiched so as to cross the portion where the fold 5 of the top plate 2 is formed, and the top plate 2 is bent from the fold 5 to prevent the top plate 2 from being kept flat. ing.

  As shown in FIG. 5, the clip 6 has a substantially U-shaped cross-section by folding a long elastic synthetic resin plate in the length direction and the like. As shown, the top and bottom (left and right in the figure) side edges of the top plate 2 are sandwiched so as to intersect the portion of the top plate 2 where the folds 5 are formed.

  Further, the clip 6 is provided with a projecting body 7 at a substantially central portion in the length direction, and an engaging portion 8 a is provided on the projecting body 7. The engaging portion 8b is detachable. As shown in FIG. 2, the clip 6 configured as described above can be moved up and down by attaching the engaging portion 8 a to the engaging portion 8 b of the top plate 2 with the top plate 2 sandwiched from the upper and lower side ends. It will not easily fall out of the side edge of the. Also, the clip 6 made in this way is removed from the upper and lower side edges of the top plate 2, and when the two cushion materials 1 are in contact with each other and overlapped as shown in FIGS. If it is sandwiched between the left and right side edges of the plate 2 and the engaging portions 8a are attached to each other, the cushion material 1 is maintained in an overlapping state, so that it does not flutter when carried and is easy to carry It becomes.

  The engaging portion 8a of the clip 6 and the engaging portion 8b of the top plate 2 can be a surface adhesive tape, a hook, a button or the like, but are particularly limited as long as they are detachable. There is no.

  The top plate 2 shown in FIGS. 6 to 9 is formed with three folds 5 so as to be positioned between the two cushion materials 1. Then, these folds 5 are made into a mountain fold state, and a wide part of the top plate 2, that is, a part with a gap S or a part that protrudes is bent so as to contact or approach the side surface of the cushion material 1. Then, as shown in FIGS. 8 and 9, the two cushion materials 1 come into contact with each other and overlap each other, which is compact. In addition, what is necessary is just to make the said space | interval S into a dimension equal to the thickness when the two cushion materials 1 are overlap | superposed in order to make the two cushion materials 1 overlap in a natural state. Further, the interval S can be made larger or smaller than the above dimensions depending on how the granular material 4 is filled in the bag body 3.

  The top plate 2 shown in FIGS. 10 to 13 is positioned between the two cushion members 1 while forming two folds 5 so as to be positioned on the outer sides of the two cushion members 1. In this way, two fold lines 5 are formed. And these creases 5 are made into a mountain fold state, and the wide part of the top plate 2, ie, the part which left | separated the said space | interval S, and the part which protruded, are made to contact or approach the side surface and lower surface of the cushioning material 1. 12 and 13, when the top plate 2 is sandwiched between the two cushion materials 1, the two cushion materials 1 are overlapped with each other. Become. The interval S is the same as that shown in FIGS. 1 to 4 and FIGS.

  Further, as shown in FIGS. 14 to 17, the top plate 2 is wider than the upper surfaces of the three cushion materials 1 so as to be suitable between the adjacent cushion materials 1. It is attached so as to leave a gap S. The cushion material 1 is assumed to have a lateral width of what is located in the center approximately twice the lateral width of that located on the left and right (up and down in the figure). Further, a crease 5 is formed at a portion where the space S of the top plate 2 is spaced, and the fold 5 can be bent. Then, when these folds 5 are in a mountain-folded state, and the portion with the gap S is bent so as to contact or approach the side surface of the cushion material 1, one piece as shown in FIGS. The cushion material 1 is in a state where two cushion materials 1 are overlapped side by side, resulting in a compact one. The interval S is the same as that shown in FIGS. 1-4, 6-9, and 10-13.
