The connection portions S arranged on the left and right sides of the communication hole G are curved so as to form a downward convexity, and are inclined such that the outer end portion is positioned higher than the inner end portion. there is As will be described in detail later, the communicating hole G is associated with the posture holding portion 22 .

In the state of use (J), the posture holding portion 22 includes a mounting surface contact portion 221 extending forward from the lower end of the main body portion 21 and whose lower surface can contact or face the mounting surface F. A document holder contacting portion 222 is provided which extends upward from the front end of the portion 221 and whose front surface can contact or face the rear surface of the document holder 1 , that is, the rear surface of the document holder body 11 .

As shown in FIG. 7, the attitude holding portion 22 can move to a position where it can cover the front side of the document holder 1 in the non-use state (K). That is, in the non-use posture (K), the placement surface contacting portion 221 and the document holder contacting portion 222 cooperate to adopt a substantially flat plate-like posture, and are positioned so as to cover the front side of the document holder 1 . It is possible.

A part of the tip edge st of the attitude holding portion 22 is configured to engage with the communication hole G in the usage attitude (J). As shown in FIGS. 3 and 6, the central portion in the left-right direction of the tip edge st, which is the upper edge of the document holder splicing portion 222, can be engaged with the communication hole G. As shown in FIG.

In other words, the upper end portion of the document holder splicing portion 222 is configured to be inserted into the communication hole G from bottom to top. As a result, the posture holding portion 22 is preferably positioned with respect to the document holder 1, and the posture of the entire bookstand A can be stabilized. 6 is an end view taken along the line XX in FIG. 3, but illustration of the pocket member 12 is omitted.

By adopting a configuration in which a part of the leading end edge st of the posture holding portion 22 can be engaged with the communication hole G, the leading end edge st of the posture holding portion 22 and the front plate member 111 constituting the document holder main body 11 are arranged. Interposition between the front plate member 111 and the rear plate member 112 becomes difficult, and damage to the connection between the front plate member 111 and the rear plate member 112 can be suitably suppressed.

When the lectern A configured as described above takes the use posture (J), the main body portion 21 of the support 2 takes a forward tilting posture. As the main body portion 21 adopts the forward tilting posture, the upper portion of the document holder main body 11 connected via the connecting portion S is flexibly deformed so as to be curved backward. will be

That is, when the lectern A transitions from the non-use state (K) to the use state (J), the body portion 21 of the support 2 shifts from the posture in which it was in contact with the document holder main body 11 to the document holder main body. 11 to a tilted posture. In conjunction with the transition of the main body portion 21, the upper portion of the flexible document holder main body 11 is deformed from a flat form to a curved form in which both side portions are located in front of the central portion. become.

As described above, the lectern A according to the present embodiment can support the document P in an upright posture with respect to the mounting surface F such as a top plate. A document holder 1 capable of holding a document P and a support 2 capable of supporting the document holder 1 in an upright position with respect to the mounting surface F are provided. The support 2 has connecting portions S which are connected to the document holder 1 so as to be positioned downward from both ends in the left-right direction toward the central portion in the left-right direction.

Therefore, it is possible to provide the lectern A that is configured to support the entire document P in a posture that allows the user to easily view it.

In other words, since the connecting portions S of the supporting member 2 are connected to the document holder 1 so as to be positioned downward from both left and right ends toward the center portion in the left and right direction, the document holder 1 moves backward. It is easy to adopt a curved form so as to form a convexity toward the edge. As a result, the document P held by the document holder 1 also tends to assume the same posture as the document holder 1, that is, it is curved so as to protrude rearward. The document P having the same posture as that of the document holder 1 can be easily viewed by the user because both sides of the front face can be easily turned inward.

Moreover, since the document holder 1 can take a curved form, it has a structure that is less likely to bend than a flat plate-shaped one. For this reason, the lectern A in this embodiment causes bending deformation with respect to the document holder 1 due to the shape of the connecting portion S of the support 2, which contributes to an improvement in overall strength. .

The upper portion of the document holder 1 has a curved shape that protrudes toward the rear. Therefore, the lower portion of the document holder 1 maintains a relatively flat shape so that it can be easily engaged with the support 2, and the intended purpose can be achieved.

A communicating hole G is provided at the boundary between the document holder 1 and the support 2, and connecting portions S are provided in pairs on the left and right sides of the communicating hole G. As shown in FIG. The support 2 includes a main body portion 21 extending from the document holder 1 toward the mounting surface F, and a main body portion 21 extending forward from the lower end of the main body portion 21 and engaging with the document holder 1 to form the main body portion 21. and a posture holding portion 22 capable of holding the posture. A portion of the tip end edge st of the attitude holding portion 22 is configured to engage with the communication hole G. As shown in FIG.

Therefore, the posture holding portion 22 is preferably positioned with respect to the document holder 1, and the posture of the entire support 2 can be stabilized. In particular, in this embodiment, by adopting a configuration in which a part of the leading edge st of the posture holding portion 22 can be engaged with the communication hole G, the leading edge st of the posture holding portion 22 can be connected to the front plate member 111 of the document holder main body 11 . and the rear plate member 112. Therefore, the connection between the front plate member 111 and the rear plate member 112 constituting the document holder main body 11 is hardly damaged.

The attitude holding portion 22 can move to a position where it can cover the front side of the document holder 1 in the non-use state (K). Therefore, the posture holding portion 22 can preferably cover the front side of the document holder 1 in the non-use state (K). Moreover, when the lectern A is not in use, it can take a compact form resembling a file, which is suitable for storage. That is, since the posture holding portion 22 of the book stand A can preferably cover the front side of the document holder 1 in the non-use state (K), the book table has a flat form that can be easily stored in a bookshelf or the like. can be adopted.

The posture holding portion 22 includes a mounting surface contact portion 221 that extends forward from the lower end of the body portion 21 and whose lower surface can contact the mounting surface F, and a front surface that extends upward from the front end of the mounting surface contact portion 221. is provided with a document holder splicing portion 222 that can be spliced to the back surface of the document holder 1. As shown in FIG.

Therefore, the posture holding portion 22 can cooperate with the body portion 21 to support the document holder 1 appropriately.

A document holder 1 forms a plate-like document holder main body 11 capable of supporting the back side of the document P, and a document housing space sp attached to the document holder main body 11 and capable of partially housing the document P. The pocket member 12 is open on one side.

For this reason, the book stand A can suitably support even a document P having a width dimension larger than that of the document holder main body 11 without difficulty. In addition, in this embodiment, the left side of the pocket member 12 is open. For this reason, even when the lectern A in the non-use state (K) is in the vertically long position, the right side wall portion 123 of the pocket member 12 functions as a bottom wall to suitably suppress the falling of the documents P. It is a thing.

That is, in the non-use state (K), the user can rotate the lectern A by 90° to the portrait orientation and treat the boundary between the body portion 21 and the orientation holding portion 22 like a back cover. At this time, the user tends to position the boundary portion, which is treated like the spine, on the left side of the user's view, like a normal file. Therefore, with the configuration according to the present embodiment, the document P held by the document holder 1 in the non-use state (K) is less likely to drop and is excellent in usability.

A document holder 1 is provided with a locking portion B capable of locking the edge of a document P. Therefore, the document P locked by the locking portion B is difficult to be displaced with respect to the document holder 1 .

The present invention is not limited to the embodiments detailed above.

Various aspects of the support can be adopted, and it is needless to say that the support is not limited to those shown in the above-described embodiments.

For example, as shown in the example of FIG. 8, the posture holding portion 22 of the support 2 may be configured. In addition, in FIG. 8, the same code|symbol is attached|subjected and demonstrated about the structure which is the same as that of embodiment mentioned above, or corresponds.

That is, in the support body 2 of another embodiment shown in FIG. 8, the posture holding portion 22 extends forward and upward from the lower end of the main body portion 21 and leans forward more than the main body portion 21 in the use state (J). and a document holder whose front surface extends downward and forward from the upper end of the forwardly inclined extending portion 221' and can contact or face the rear surface of the document holder body 11, that is, the rear surface of the document holder main body 11. A body splicing portion 222 is provided. Even with such a configuration, the posture of the lectern A can be maintained in the state of use (J) without difficulty, so that the intended purpose can be achieved.

The main body of the document holder does not have to have a structure in which the front plate member and the rear plate member are superimposed as shown in the above-described embodiment, and the document holder body is made of a flexible plate-like member. It may constitute the main body.

The support may be configured to be attached to the document holder via a hinge forming the connection.

Of course, the front plate material and the rear plate material are not limited to those bonded by spot welding. For example, the document holder main body may be configured by bonding a front plate member and a rear plate member with an adhesive.

The connection part of the support does not have to be a pair on the left and right, and for example, it may be connected to the document holder in a curved form so as to form a downward convexity. . Moreover, the connection portion of the support is not limited to a linear continuous portion, and may be intermittent. In other words, the intended purpose can be achieved if the connecting portion as a whole adopts a form in which it is connected to the document holder so as to be positioned downward toward the central portion in the left-right direction. It is.

It goes without saying that the document may be anything as long as it can be an object to be browsed. For example, the document may have any size and shape as long as it can be supported on the lectern.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the scope of the present invention.
