Description

[Detailed description of the device] << Industrial application field >> The present device is detachably attached to the front part of a bookshelf attached to a desk, and character patterns, maps, kanji, alphabets, etc. are printed on both front and back sides. The present invention relates to a study board for a study desk including a set of a plurality of sheets and a sheet holding frame detachably attached to the front portion of a bookshelf attached to a desk and detachably holding the set of sheets. .

<< Conventional Technology and Problems >> Conventionally, each of the sheets used for the study board has one side (probably the front side) as a part of a learning desk.
Various character patterns that have the function of decorating the study desk are displayed, and various maps that have the function of assisting learning and tables of Chinese characters and the like are displayed on the back side of the sheet. It was stored in the frame.

Then, when changing the sheet displayed in the display window of the sheet holding frame to the desired one, pull out all the sheets from the sheet holding frame, check the front and back of each sheet, find the desired pattern, etc., It was very troublesome because the sheets had to be mounted in the sheet holding frame again at the position adapted to the display window.

<< Purpose and Structure of the Present Invention >> The present invention has a simple structure and allows not only easy extraction and mounting of a desired sheet to the sheet holding frame, but also the contents of each sheet even when mounted on the sheet holding frame. The purpose of this study is to provide a study board of a study desk that can be seen at a glance. Its structure is composed of a set of multiple sheets and a sheet holding frame that holds the sheets. Is formed, a display window of the sheet is formed on the front surface of the sheet holding frame, while each sheet has a heading protrusion that displays the contents of the front and back such as a pattern, and each heading protrusion is a sheet. Are polymerized in the same direction on the front and back,
It is formed so as not to overlap the respective heading protrusions, and is formed so as to project outside the sheet holding frame when mounted on the sheet holding frame.

<< Example >> Hereinafter, an example is described based on a drawing.

In FIG. 1, reference numeral 1 indicates a sheet holding frame, and reference numeral 2
Shows a set of seats mounted on the seat holding frame 1.

The seat holding frame 1 is composed of a front frame 3 integrally formed of a synthetic resin material and a back plate 4 made of cardboard or the like screwed to the back side of the front frame 3.

The front frame 3 is composed of left and right upper and lower edges 31, 32, 33, 34, a display window 30 of the seat 2 is formed in the center of the front surface, and a lower end of the display window 30 has a projecting edge 35 for placing a writing instrument or the like. Are connected to the lower edge 34.

Then, on the back surface of the left and right edges 31, 32, there are formed rear projecting edges 311 and 321 smaller than the outer peripheral edges 36 and 37 in the depth direction, and inner surface edges 312 and 322 smaller than the rear projecting edges 311 and 321. There is.

Further, leg projections 341, 341 contacting the top surface of the top plate 10 of a learning desk or the like are continuously provided on the lower surface of the lower edge 34 on the left and right end portions, and the leg projections 341, 3
A lower projecting edge 342 having the same size as the outer peripheral edges 36, 37 in the depth direction is formed on the back side of the upper part of 41, and has the same size as the rear projecting edges 311 and 321 above the lower projecting edge 342. A lower rear projecting edge 343 is formed, and the rear end of the placing projecting edge 35 projects rearward to the same position as the rear ends of the inner surface edges 312 and 322.

The upper edge 33 has the same depth dimension as the inner surface edges 312 and 322, and is provided with a predetermined distance on the front side to form index holes 331 ... At the left and right ends of the upper surface, locking projections 3 that are locked from below to a locking portion 101 provided on a part of a bookshelf 100 mounted on the top plate 10 of the study desk.
32 and 332 are formed so as to project upward.

Then, the outer peripheral edges 36, 37 of the left and right edges 31, 32 and the rear projecting edges 311, 3
A connecting cylinder (not shown) to which the back plate 4 is screwed is formed at the upper and lower ends of the space 21.

The back plate 4 is made of cardboard or the like, the front surface of the peripheral end portion excluding the upper end is in contact with the rear end edges of the rear projecting edges 311, 321 and the lower rear projecting edge 343, and the left and right end surfaces and the lower end surface are outer peripheral edges. It is screwed to the back surface of the front frame 3 in a state of being positioned on the inner surface side of the rear edges 36, 37 and the lower protrusion 342.

That is, a seat mounting hole 300 for mounting the seat 2 is formed on the upper end surface of the seat holding frame 1 between the rear end of the upper edge 33 and the upper front surface of the back plate 4, and the left and right end portions of the back plate 4, A seat locking groove 40 is formed between the front surface of the lower end portion, the rear ends of the inner surface edges 312 and 322, and the rear end of the mounting projection edge 35.

In the case of the present embodiment, the sheets 2 ... Are made up of a set of three sheets, and the sheets 21, 22, and 23 are printed with predetermined patterns on both front and back sides, and the patterns are printed on the upper end. Heading protrusions 211, 212, 221, 222, 231, 232 for displaying content
Are formed.

The heading protrusions 211, 212, 221, 222, 231, 232 are seats 2
Is formed in a size projecting above the upper edge 33 in the state where it is attached to the sheet holding frame 1, and the index hole 331
Contents printed on the front and back sides are described in the parts corresponding to.

Also, the heading protrusions 211, 21 of the respective sheets 21, 22, 23
2, 221, 222, 231, 232, each having the same interval, when each sheet 21, 22, 23 is superposed in the same direction on the front and back,
In order to prevent overlapping, the heading protrusions 211 ... Are formed so as to be laterally displaced with respect to each width dimension.

The present invention is configured as described above, and the sheets 21, 22, and 23 are superposed in the same direction on the front and back sides and mounted in the seat holding frame 1 through the seat mounting holes 300 (state shown by a fourth phantom line), Heading projections 211, 212, 221, 222, 23 of each sheet 21, 22, 23
The upper portions of the reference numerals 1 and 232 project above the upper edge 33 in a state where the positions thereof are laterally displaced.

Then, at this time, a portion in which the contents of the sheet 21 or the like such as the heading protrusion 211 is described is displayed in the heading hole 331 ....

Next, when changing the picture or the like facing the display window 30 to the picture or the like described on the sheet 23, a heading hole 33 with desired contents is displayed.
When the heading protrusion 231 above 1 is pulled out upward, the desired sheet 23 is pulled out upward.

Next, the seat 23 is placed in the front row and mounted in the seat holding frame 1, and desired contents are displayed on the display window 30.

Incidentally, in the embodiment, the contents of the sheet 2 are displayed in the index holes 331 ... However, the index holes 211 ...・ ・
The contents may be displayed in the part of.

Further, in the embodiment, two heading protrusions are formed on each sheet, but it is also possible to form one heading protrusion and display the contents of the front and back sides on the left and right or on the top and bottom.

<Effect> As described above, according to the present invention, the heading protrusions are formed at different positions so that they do not overlap each other, and the contents of the sheets are displayed on the heading protrusions. The contents of each sheet can be identified at a glance even when it is mounted, and the heading protrusion protrudes outside the sheet holding frame in the mounted state, so the seat facing the display window was changed. In this case, only the desired sheet can be easily taken out from the sheet holding frame by simply pulling out the heading protrusion in which the desired content is displayed, and it is very easy to change the sheet.
