Description

  SUMMARY OF THE INVENTION An object of the present invention is to provide an auxiliary tool that makes it easy to see books, visual media such as tablet PCs, and other general documents, and is advantageous for use such as writing on a table. And

  A book stand has existed for a long time, but it seems that a book stand that can be used on a table is not used much because it requires space saving and a simple structure.

  On the other hand, tablet PCs have started to spread recently, but tablet PCs are heavy for their size and are inconvenient to hold for a long time, and when used together with PCs, other books and documents As in the case of books, the workability is reduced by arranging everything flat on the table.

  Whether it is a book, a tablet PC, or any other document, it would be convenient if each could be installed stably at an easy-to-view angle on the table, but until now there is no product that can be used in an easy-to-use style. It seems that is the actual situation.

  Each of the above-mentioned patent documents showing prior art is a table-type writing stand intended for simplicity, but in common, it is close to or more than the occupied area of a book, a tablet, a clipboard or the like. In addition to having a mounting plate with an area, a base that supports it from the back on the table (support rod, plate), and possibly a base plate that combines both the mounting plate and the support, in some cases It is common to have a mechanical structure that joins common components. In other words, regardless of whether it is actually connected together or separated, it has a mechanical coupling part of two or more parts, so that the coupling part that adjusts the angle moves or moves the coupling part itself This leads to some instability factors (collapse of structure, ease of falling down, ease of breakage) and the size of the occupied space.

  In many cases, the angle can be adjusted, but the range of adjustment is quite limited, and it seems that it is not possible to realize a cover that can cover a low angle close to flat to a steep angle close to a right angle.

  Furthermore, if the weight of the load is large, it must be strong enough to support it. If the strength of the load plate is small or the clipboard format that supports several document sheets is like a tablet or large book There are cases where it is not possible to deal with heavy objects.

  The above four points, that is, instability caused by having a structure with a mechanical variable part, fragility, a large occupied area or a large occupied space are required, an angle adjustment range is limited, and a heavy object It is an object of the present invention to solve these four points.

  A cylinder (1 in FIG. 1 represents a cross-sectional view) of a cylinder (not necessarily a cylinder as described in the claims, but represented as a cylinder in the text as a representative example) vertically. Is placed so that the ridgeline of the cylinder is in contact with the top of the table, and the load is placed on the flat surface (hereinafter referred to as the main plane), so that the tilt of the load can be reduced by simply moving the main body back and forth. Can be adjusted steplessly in the middle angle range (a, b in FIG. 1).

  In this case, there is a possibility that the load will slide down or the body position may be shifted back and forth simply by placing the load, so in the case of a book, in the case of a book, the page press (2) or the stopper that stops the slide ( 6) Or other components for fixing the main body and the load are necessary.

  Usually, the components to be pressed from the top are elements attached to many bookshelves, such as book page holding clips, and in the case of the present invention, the attached components such as clips on the left and right sides of the main body are fixed. It can be realized by adding (hereinafter referred to as page press as a representative example).

  The elements (11 and 12 shown in FIG. 4) that are not fixed from above, but are fixed to or connected to the mounting surface of the main body and the mounting object, such as a magnetic material and a magnetic adsorbing material, a pair of surface fasteners, pins and pin holes 15 is also possible. In this case, the length of the column body can be made shorter than the lateral width of the mounted object, further saving space. It seems that surface fasteners are already used for fixing to wall surfaces, etc. on tablet PCs etc., but for books etc. that can not be directly attached with this type of fixing element, the conventional type in which the main body is mounted in some way A method of mounting or mounting the fixed material or the connecting structure on a mounting plate corresponding to only the mounting plate portion of the book stand and mounting the mounting object indirectly is also possible (FIG. 4).

  In the following description, the mounting plate is simply mounted as shown at 15 in FIG. 4 or is mounted as shown at 15 in FIG. 6 in addition to a structure in which the mounted load is fixed by some other page pressing mechanism. It also means a material that is integrated with an object and functions as a mounting plate.

  For example, when there is a weight such as a tablet PC and there is no need to hold the page, it can be replaced by a stopper (6). In that case, a structure that pulls out from the main body like a tape measure can be attached to the main body. Possible (Fig. 3). In the case of this figure, the stopper is joined to a sheet (cloth or the like). This type of stopper is not necessary if the mounting portion with the column body can be fixed, but conversely, by using this stopper, it is not necessary to bond the adhesive material to the mounted object or the mounting plate.

  When the inclination is set to a steep angle (c in FIG. 1), the center of gravity comes behind the fulcrum of the column, and as a result, it falls back. In this case, the main body column body is supported behind (c-1), or a support body composed of a column body different from the main body that supports the main body column body at a position where the main body column body is raised from the table top surface is combined. Can realize a steep angle (c-2). Alternatively, the steep angle can be realized by inserting a spacer between the main body column and the mounted object without tilting the main body column to a steep angle (FIG. 7). Various additional structures are conceivable for achieving steep angles, but the use of a back support or spacer can maintain consistency with the simple structure of the present invention. This support or spacer is a column like the body, but these columns (3, 16) need not have the same length as the columns of the body.

  If the back support (3) of this column body is a material having a certain degree of friction coefficient as in the case of the main body, it is considered that it is fixed only by being in close contact with the cylindrical portion of the main body (c-2 in FIG. 1). ), A method of providing a pin (4) as a connecting mechanism for securely fixing, and fitting the pin into a pin hole (5) provided in the main body (c-1 in FIG. 1) and the like.

  This back support is necessary when the tilt angle is large and the entire center of gravity including the load comes behind the fulcrum, but it is small even when it is ahead of the fulcrum. Therefore, it is possible to prevent backward rotation when pressed (b in FIG. 1).

  On the other hand, in the case of a steep angle such that the center of gravity is behind the fulcrum, it is possible to stably support the main body column in a shape that can be supported at a position where it is lifted from the table top (c-2 in FIG. 1). .

  In the present invention, the stability can be basically obtained by bringing the center of gravity of the entire body to the front, and the fulcrum of the main body columnar body located further rearward. It is possible to move the fulcrum backward by enlarging the main body column, but on the other hand (3) At the same time as (1) it becomes impossible to adjust to a low angle, (2) bulk and weight increase, (3) There is a disadvantage that the center of gravity of the main body column moves backward, so it is meaningless to make the column larger than necessary. However, in order to bring the position of the center of gravity forward, it is possible to use a heavy material in the foreground by making the back cavity as shown in FIG.

  As intended, it does not occupy a place on the desktop, is simple in structure and is not easily damaged, and supports a wide range of practical and wide-ranging tilt angles (books, clipboards, tablet PCs, and other visual media). A desktop writing stand is realized.

Sectional drawing which shows an example of the structure which moves the gravity center of a main body column to this side.

  As the page presser, various existing structures such as various clips can be considered, and an example is shown in the section of the embodiment.

  When fixing on both sides of the mounted object, it is usually necessary to fix both sides, but the width of the mounted object usually varies. Therefore, the left and right sides can be separated into a two-body structure. (The figure is omitted).

  Instead of the left and right two-body structure, it is also possible to provide a stretchable structure that can adjust the left and right length. (The figure is omitted because there are various possibilities).

  FIG. 2 shows an example in which an elastic body is used as a page presser for fixing a load. The elastic body part to be pressed directly can be realized by using a spring, a cushion material, or both.

  If a rotatable roller is used for the part that directly touches the load, it will be easier to respond to page turning of the book.

  In the case where a hard material such as a tablet PC that has little change in thickness is targeted, it can be considered that only a cushion material can be used.

  In the case of a tablet PC or the like that uses an adhesive material (11, 12) without using a page press or the like, it is composed only of elements whose cross section is shown in FIG. The horizontal width of the main body column (1) can be made shorter than that of the mounted object, and the horizontal width of the back support (3) can be made shorter than that of the main body column.

  Various methods such as pins, rails, grooves (FIG. 4) and the like are conceivable as a mechanism for connecting the mounting plate that can fix the mounted object to the main body (1).

  FIG. 3 is a cross-sectional view of an example of a system using a stopper. Cloth etc. can be used as a raw material of the sheet | seat (13) which is adhere | attached on the stopper (6), unwound from the core (14) accommodated in the main body (1), and pulled out.

  FIG. 4 is an example of a method of using a dedicated mounting plate on which a mounted object is placed. In this embodiment, a large number of grooves carved on the contact surfaces of both the column of the main body and the mounting plate are engaged so that they are connected like a gear. In this connection method, the bite is disengaged by lifting the mounting plate, and it is fixed by placing it on the position where the groove and the mountain bite, so it cannot be slid continuously.

  One of the merits of using this type of mounting plate is that the center of gravity can be moved toward the front, that is, downward. By bringing the center of gravity forward by combining the material and structure, the tilt angle can be adjusted to a steeper angle without using a back support.

  As another merit, it is possible to add a mechanism according to the purpose of the mounted object, such as a page presser, to the mounting plate itself. Disadvantages include that it is bulky and increases in weight by the mounting plate, and is inferior to other methods in portability.

  FIG. 5 shows an embodiment in which the support can be raised so that the load can be lifted away from the table top. Although it is suitable when a fixing material such as a hook-and-loop fastener is used, the angle adjustment range is limited as compared with the case where the mounted object contacts the table top surface.

  Even when using the mounting plate as shown in FIG. 4, it is possible to lift the mounted object to a high place away from the table top surface by the back support, but the weight increases, so that compared to the case of using a fixing material. This further limits the range of adjustment of the angle. In addition, a stronger coupling mechanism and a stronger and more stable support are required.

  Also when it fixes by the page press added to the both ends of the main body like FIG. 2, a mounted object can be maintained in the high place away from the table top surface by the back support body. Also in this case, the angle adjustment range is limited, and at the same time, in order to prevent slipping down, there is a need to more firmly fix with the page presses at both ends.

  In the case of a mounting plate (Fig. 6) that functions as a mounting plate by being integrated with the mounting object, it can be made of a flexible, thin and lightweight material such as rubber, so it is lifted to a high location away from the table top surface. In some cases, it may be steeper than a thick and heavy mounting plate.

  When the steep angle is realized by using the spacer (16), it becomes somewhat unstable, and there is a possibility of falling when the upper part is strongly pressed. Therefore, it is desirable to use the back support (3) together.

  It is thought that the range in which the reading stand can be used for all office work and reading on the table will dramatically expand.

  Furthermore, since it is suitable for tablet PCs that have recently become widespread, it can be expected that the usefulness of tablet PCs will increase.
