  However, the table disclosed in the above publication has a configuration in which a long groove is formed in the vertical direction to adjust the height of the table plate steplessly and is fixed with a bolt at a desired height position. If the bolts are loose or loose during use, and if the table plate is pressed firmly when standing up, the table plate must be lowered and the height must be adjusted again. The same applies to the case where the table board is used as an auxiliary table when standing up.If a disabled person or an elderly person presses the table board from above as an auxiliary table, the table board suddenly descends and balances the body. There was concern that it would collapse and fall. Further, in the conventional table, since the abdomen is pressed against the edge of the table plate during use, the abdomen becomes painful or painful when it is in contact with the table plate for a long time.

  The present invention has been developed in view of the above points, and the object of the present invention is to provide a table plate that can be used while sitting on a chair or wheelchair, or sitting or sitting on a bed. It can be used by adjusting the height, and even if the table plate is pressed firmly from the top, the table plate does not fall down and can be moved more easily. It is to provide a table that is not squeezed.

  In order to achieve the above-mentioned object, the present invention according to claim 1 is a pair of telescopic devices provided with a table plate and holes provided on both sides of the table plate so as to be moved up and down together with the table plate and positioned at predetermined intervals. A member and a hole corresponding to the above-described hole of each expansion / contraction member, and each expansion / contraction member is supported so as to be vertically movable, and both expansion / contraction members are inserted into the holes at a desired height position. A pair of side support members fixed via a tool, a lower support member fixed to the lower part of each side support member and connecting the both side support members, and a plurality of casters provided at appropriate positions of the lower support member The configuration is as follows.

  According to a second aspect of the present invention, there is provided a table plate, a pair of expansion / contraction members provided on both sides of the table plate and provided with holes that can be moved up and down together with the table plate and positioned at predetermined intervals, and each of the expansion / contraction members A hole corresponding to the above-mentioned hole of the member for use is provided, and each of the members for expansion and contraction is supported so as to be movable up and down, and the members for expansion and contraction are fixed at a desired height position via a fixing tool inserted into the hole. A pair of side support members, a linear lower support member fixedly provided at the lower portion of each side support member, and casters provided before and after each lower support member are provided.

  Further, the present invention described in claim 3 is a configuration of the table of the invention described in claim 1 or 2, wherein one side edge of the table plate facing the user is curved inward to provide a recess. It is.

  In the table of the present invention, it is possible to adjust the height of the telescopic member by moving it up and down so that it is easy for the user to use, so that it can be used comfortably without deteriorating the posture or being difficult to use. it can. In addition, since casters are provided, it can be easily moved and the position of the table relative to the chair can be easily adjusted by moving the table while sitting on the chair. Convenient. Further, even if the table plate is pressed firmly from above, it does not drop and the table height is lowered, and it is not necessary to adjust the height again.

  In addition, a table with a linear lower support member provided at the bottom of each side support member can be used with the table plate positioned on the bed so as to straddle the bed, and even the sick and disabled can sit on the bed. Work with tables.

  In addition, since the concave portion is provided on one side of the table board, the abdomen is not compressed by the place where the table board faces in use, and the work using the table can be performed in an easy posture.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 3 show a first example of a table 1 according to the present invention. The table 1 includes a table plate 2, a pair of telescopic members 3, a fixture 4 for height adjustment, and a pair of side supports. The member 5, the lower support member 6, the caster 7, the horizontal bar 16, and the table plate 2 and a fixture made up of a large number of bolts and nuts for connecting the members (some of the symbols in the drawings are omitted). ing. The other members excluding the illustrated fixtures are made of wood.

  More specifically, the table plate 2 is a wooden board having a slightly rounded outer peripheral edge and a slightly rectangular shape. The outer peripheral edge on one long side is formed in an arc shape and curved inward. An elliptical recess 8 is formed. In addition, through holes 10 are formed at the four corners of the table plate 2 through which bolts 9 serving as fixtures are passed. The concave portion 8 is assembled on the front side (side facing the user) when the table 1 is assembled.

  The pair of expansion / contraction members 3 is formed by assembling a longitudinal member 3a and a transverse member 3b in a rectangular frame shape, and a hole 11 for attaching the bolt 4a and nut 4b of the fixture 4 to a predetermined position of each longitudinal member 3a. Are formed in a column at a predetermined interval. Furthermore, the hole 12 which attaches another fixing tool (a symbol is abbreviate | omitted in a figure) is formed also in the upper part side of each vertical member 3a.

  The pair of side support members 5 have substantially the same shape as the above-described expansion / contraction member 3, and holes 13 and 14 are formed in the upper and lower portions of the vertical member 5a, respectively. The holes 13 on the upper side are formed at a predetermined interval in the vertical direction, that is, with the same interval as between the holes 11 of the expansion / contraction member 3 described above. The hole 13 is a through hole.

  The lower support member 6 has a U-shape in plan view (or H-shape in plan view) composed of a pair of side lower ridges 6a and a span ridge 6b provided near one end of the lower ridges 6a on both sides. . The hanging rod 6b is located in the lower part of the back side of the table 1.

  The table 1 is assembled by connecting the above-described table plate 2 and each member at a predetermined position with each fixture. And when connecting a pair of expansion-contraction member 3 and a pair of side part support member 5 with the fixing tool 4, the height of the upper surface 2a of the table board 2 is adjusted to the height which the user of the table 1 desires. Then, both members 3 and 5 are connected by the fixture 4.

  In the example shown in the figure, each of the expansion / contraction members 3 is provided with seven holes 11 in a column so that the height can be adjusted in six steps, but more holes are provided so that the height can be adjusted in seven steps or more. Also good. Of course, you may provide few holes so that height can be adjusted to five steps or less. The interval between the holes 11 in the column can be increased to form the holes 11 or can be reduced to form the holes 11. Of course, the interval between the holes 11 need not be constant. Even in this case, it is a matter of course that the positions of the holes 11 of the opposing expansion / contraction members 3 are the same.

  In the table 1 assembled by adjusting the height in this way, the user's height can be obtained by hanging the chair 15 on the chair 15 as shown in FIG. The table 1 can be used comfortably without being pressed against the abdomen by the edge of the table plate 2 during use, and without having a bad posture or being difficult to use. In addition, since the table 1 is provided with casters 7, it can be moved easily, and the position of the chair relative to the table 1 can be adjusted by moving the table 1 side during use. It is very convenient for disabled and elderly people.

  Further, in this table 1, the pair of expansion / contraction members 3 and the pair of side support members 5 are set to a desired height, and the bolts 4a correspond to the holes 13 of the side support members 5. 3, and screwed and connected to the nut 4 b inserted into the hole 11 of the expansion / contraction member 3, so that the expansion / contraction member 3 can be held even when the table plate 2 is strongly pressed from above during use of the table 1. There is no possibility that the height of the table plate 2 is lowered due to the downward displacement.

  FIGS. 4-6 is a figure regarding the table 1 concerning this invention of the 2nd example. For the sake of convenience, the reference numerals in the figure use the same reference numerals as those in the first example, and the constituent parts different from the first example will be described, and the other parts will be assigned the same reference numerals as in the first example and the description will be omitted. .

  In the table 1 of this example, the table plate 2 has a rectangular shape close to a square shape, and when attached to the expansion / contraction member 3, half of the table plate 2 protrudes outward from the end of the short side of the expansion / contraction member 3. It is a size. Further, the concave portion 8 at one long side portion of the table plate 2 has a substantially semicircular shape, and is large enough to fit around the abdomen of a person who uses the table 1 into the concave portion 8. Further, the through holes 10 to which the bolts 9 are attached are provided at both corners of the table plate 2 on the opposite side of the recess 8 and at both sides in the middle of the table plate 2. Of course, the table 1 also adjusts the table plate 2 to a desired height by extending or contracting both the expansion and contraction members 3 with respect to the both side support members 5, and connecting the members 3 and 4 with the fixture 4. Can be fixed. Other configurations are the same as those of the table of the first example described above.

  Also in the table 1 of this example, by adjusting the height of the table board 2 as described above, even a person riding in a wheelchair can enter the area of the abdomen directly into the recess 8 of the table board 2 as shown in FIG. By confronting the table 1 in this way, the table 1 that is at the height of the user can be used comfortably without any bad posture or difficulty in use. Further, since the body (around the abdomen) can be placed in the recess 8 in the table 1, the table plate 2 can be rested with an elbow when resting. Moreover, since the caster 7 is provided similarly to the 1st example, the table 1 side can be moved and the position with respect to a wheelchair can be adjusted.

  7 to 9 are diagrams relating to the table 1 according to the third embodiment of the present invention. For the sake of convenience, the reference numerals in the figure use the same reference numerals as those in the first example, and the constituent parts different from the first example will be described, and the other parts will be assigned the same reference numerals as in the first example and the description will be omitted. .

  In the table 1 of this example, the table plate 2 has a rectangular shape longer than the table plate of the first example, and the length is a little longer than the width of the bed. The horizontal bar 16 is also approximately the same length as the table plate 2. Also, linear lower support members 17 are fixed to the lower portions of the respective side support members 5 by fixtures. Casters 7 are provided before and after each lower support member 17, respectively. Further, the concave portion 8 on one long side of the table plate 2 is substantially semi-elliptical and has a size such that the abdomen of a person who uses the table 1 slightly enters the concave portion 8. Of course, this table 1 can also adjust the table board 2 to desired height by extending or contracting both the expansion-contraction members 3 with respect to the both-side support members 5. Other configurations are the same as those of the table of the first example described above.

The table 1 in this example also adjusts the height of the table plate 2 and is placed on the bed so as to straddle the bed as shown in FIG. 9, so that a letter or a book can be read while sitting on the bed. It is possible to perform work using the table 1 on the bed. Therefore, the sick person etc. can work using the table 1 without leaving the bed.
Further, since the table 1 is also provided with the casters 7, it can be moved easily, and the table board 2 can be positioned at the optimum position of the body without moving the body back and forth on the bed when in use. Of course, the table plate 2 can be separated from the body by simply pushing the table 1 after use. Further, when standing up from the bed, it is possible to stand up with a hand on the table plate 2, and the table 1 can be used with peace of mind without lowering the table plate as an auxiliary tool when standing up. Further, by installing the table 1 along the side of the bed, it is possible to use the hand with the bed as a chair, and it is not necessary to stand up from the bed and go to the place where the table is.
