Description

The present invention relates to a clipboard that holds a holding object such as paper in a holding portion.

Conventionally, a clipboard in which a pressing part is formed to hold paper or the like at the end of a plate-like board part has been widely used, and such a clipboard exerts a pressing force toward the board part. The holding object such as paper sandwiched between the pressing portion and the board portion is held by the pressing force.

  There are various configurations of the pressing portion, such as a configuration using a metal frame and a spring (see Patent Document 1 below). FIG. 6 shows an enlarged side view of the vicinity of the pressing portion of the conventional clipboard as described above. The clipboard of FIG. 6 has a pressing part 13 formed at the end of the board part 12 by extrusion deformation, and is used with a holding object sandwiched between the board part 12 and the tip part of the pressing part 13.

In general, when a clipboard is inserted with holding objects one by one, the holding object is slid along the board part toward the pressing part, but the pressing part exerts a pressing force toward the board part. In the case of the structure to be held, if the holding force of the holding part is loosened to try to pinch, the holding force of the holding object that has already been pinned becomes weak, and the holding object that has been pinched as the new holding object slides Moved, and a new holding object could not be sufficiently sandwiched between the holding portions, or a holding object that had already been sandwiched shifted.

JP-A-10-217661

  It is an object of the present invention to provide a clipboard that can smoothly insert a new holding object into a pressing portion without causing a problem such as a holding object that has already been inserted being shifted.

In order to solve the above problems, the present invention has the following configuration.

(1) A board part and a pressing part formed on the board part so as to be rotatable and applying a pressing force toward the board part, and one side of a penetrating part formed on a part of the board part. The holding part forming part that protrudes more toward the back side of the board part is integrally molded with a resin material, and the holding part forming part is pushed and deformed from the through part to the front side of the board part to deform the holding part. A clipboard formed, wherein the clipboard has one or more protrusions protruding toward the board at the tip of the pressing portion.

(2) The clipboard according to (1), wherein the protrusion has a substantially rectangular plate shape.

Since the clipboard of the present invention has a protruding portion that protrudes toward the board portion at the distal end portion of the pressing portion, even when the holding objects are added and pinched one by one, the holding object that has already been pinched is inserted into the protruding portion. Because it does not slip any more after it hits, even if a new holding object is slid, the holding object that was pinched does not move, and the new holding object can be pinched securely and smoothly into the holding part, and the holding object that has already been pinched Will not slip.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. However, the present invention is not limited to the following embodiments.

FIG. 1 is a front view of a clipboard as an example of an embodiment of the present invention, and FIG. 2 is a rear view of the clipboard of FIG. The clipboard 1 of FIGS. 1 and 2 includes a board part 2 and a pressing part 3. As shown in the enlarged side view of FIG. 3, the board portion 2 has a shape in which one end thereof is inclined to the front side through the curved portion 4 (shown by a hatched portion in FIGS. 1 and 2). Yes. The board part 2 is formed with a through part 5, and the pressing part 3 extends from one side of the through part 5 to the front side of the board part 2 and is pressed against the board part 2 beyond the through part 5. On the board portion side (that is, the back surface side) of the distal end portion 3a of the pressing portion, two substantially rectangular plate-like projections 6 and 6 projecting into the through portion 5 are formed. In addition, the clipboard 1 of FIG. 1 has a hole 7 for use for hanging.

  The clipboard of FIGS. 1 and 2 is formed as follows. First, as shown in an enlarged side view of the board portion 2 in which a through portion (indicated by reference numeral 5 in FIG. 1) is partially formed, and protrudes toward the back side of the board portion from one side of the through portion. The base member having the pressing portion forming portion 3 ′ is formed by integrally molding with a resin material. Next, the pressing portion 3 shown in FIGS. 1 and 2 is formed by pushing and deforming the pressing portion forming portion 3 ′ of the base member from the penetrating portion 5 to the front side of the board portion. Due to the flexibility of the resin material, the pressing portion 3 can be rotated with respect to the board portion, and since the pressing portion 3 is formed by extrusion deformation, the pressing force is applied toward the board portion 2 by the restoring force of the resin material. Have pressure.

  FIG. 5 is an enlarged side view for explaining the operation of the clipboard of FIG. As shown in FIG. 5, when the board portion end 2a above the pressing portion 3 is pressed with a finger or the like toward the back side (indicated by an arrow A in FIG. 5), it is bent due to the flexibility of the resin material. The part 4 bends to the back side, and the pressing part 3 is rotated to the front side around one side of the penetrating part (one side connecting the reference numerals 5a and 5a in FIG. 1) (indicated by an arrow B in FIG. 5). ) As a result, the tip of the pressing portion 3 that has been pressed against the board portion 2 is separated from the board portion, and a gap is generated between the tip of the pressing portion 3 and the board portion 2. When a holding object such as paper is inserted from below the board part toward the gap (indicated by arrow C in FIG. 5), the holding object that has already been sandwiched with the movement of the newly inserted holding object 8a. A force in the direction of arrow C is also applied to the target 8b, and the holding target 8b also tries to move in the direction of arrow C. However, the target 8b hits the protrusion 6 provided on the tip 3a of the pressing portion and does not move any further. Accordingly, the holding object 8a can be securely and smoothly sandwiched between the pressing portions 3 without the holding object 8b being displaced and without the movement of the new holding object 8a being hindered by the displacement of the holding object 8b. Since the conventional clipboard does not have a protruding portion, the holding object already pinched slides with the new holding object, and it is difficult to smoothly pinch the new holding object. When the force applied to the board end 2a is removed, the pressing portion 3 rotates in the reverse direction, returns to the original state, and the new holding object 8a is also held.

  In the present invention, the shape of the protrusion is preferably a substantially rectangular plate shape as in the above embodiment, but it is preferable to prevent the holding object already sandwiched from slipping. Other shapes such as a circular plate or a column may be used. Also, the number provided may be two as in the above embodiment, or three or more and one. FIG. 7 shows an embodiment in which one long rectangular plate-shaped protrusion having a width equal to the width of the pressing portion is provided.

  In the present invention, the size of the protruding portion can be appropriately set in consideration of the installation position of the protruding portion, the size of the pressing portion, and the range in which the pressing portion can be rotated from the board portion. It is necessary to set so that the object to be held can be brought into contact with the protrusion. That is, when the holding part is rotated and the tip of the holding part is separated from the board part, the tip of the protruding part reaches the front side surface of the board part or its extension surface, or the front side surface of the board part or its extension. Although it is preferable to reach the back side from the surface, it is sufficient that the shift of the object to be held can be prevented even if the tip of the protrusion is slightly away from the front side surface of the board portion or its extended surface. Moreover, when the front-end | tip of a projection part reaches | attains the back side from the front side surface of a board part, it is necessary to make it not prevent the board part standing still.

  Further, the angle of the protrusion with respect to the pressing portion is not particularly limited as long as the holding portion can be abutted against the protruding portion while the pressing portion is rotated and the tip of the pressing portion is separated from the board portion. It is effective to make the protrusion and the holding object form an angle of 90 degrees or more in a state in which the tip of the part is separated from the board part.

  The clipboard of the present invention includes a board part and a pressing part that is formed to be rotatable on the board part and applies a pressing force toward the board part, and protrudes toward the board part on the board part side of the pressing part. Other configurations such as shape and size other than the configuration having projections and extruding and forming a base member integrally molded with a resin material are not particularly limited as long as they do not hinder the operation of the present invention. Not. Since the clipboard of the present invention is formed by extruding and deforming a base member that is integrally molded with a resin material, the protrusion can be easily formed, and the pressing part is large and does not separate from the board part. The effect of providing is particularly effective. In addition, since other materials such as metal are not used, it is easy to separate and recycle. As the resin material, a material generally used for a clipboard can be used.

The clipboard of the present invention can be used particularly suitably as a clipboard for holding and storing documents, slips, memos, and other holding objects because the holding objects such as paper can be smoothly inserted into the holding portion one by one.

It is a front view of the clipboard which is an example of an embodiment of the present invention. It is a rear view of the clipboard of FIG. FIG. 2 is an enlarged side view of the vicinity of a pressing portion of the clipboard of FIG. 1. It is a side surface enlarged view which shows the state before the press part formation of the clipboard of FIG. It is a side surface enlarged view explaining the effect | action of the clipboard of FIG. It is a side surface enlarged view near the holding | suppressing part of the conventional clipboard. It is a back surface enlarged view near the holding | suppressing part of the clipboard which is the other example of embodiment of this invention.
