Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover structure,
More specifically, the present invention relates to a cover structure that can maintain a closed posture in which a front plate member and a back plate member that are openable and closable are combined.

[0002]

2. Description of the Related Art Conventionally, notepads have been used in offices and the like. This paper clip is constructed by fixing a binding tool on the inner surface side of the cover, and the cover structure has a back plate member to which the binding tool is fixed along the upper edge, and a left-right direction of the back plate member. It is composed of a front plate member connected to one end side, and can be opened and closed by interposing a bendable hinge portion between the front plate member and the back plate member. When using such a paper clip, the upper end of the writing paper is bound by a binding tool while the writing paper is placed on the back plate member, and the back plate member is used as a base plate for writing. When not in use, the front plate member is folded to a position where it covers the writing paper.

However, in the case of a paper clip provided with a front plate member, the front plate member is kept in an open position with respect to the back plate member and the presence of the front plate member interferes with the writing operation described above. You must keep it from becoming. In this case, it is necessary to open to the position where the outer surface side of the front plate member overlaps the outer surface side of the back plate member, but this state must be held by the hand opposite to the hand for writing. Therefore, there is an inconvenience of giving a fatigue feeling to the holding hand. This is because the front plate member and the back plate member are composed of a single resin sheet material, and the resin sheet material has sufficient hardness to have a planar shape, and the front plate member is always present. And the inner surface of the back plate member are configured so as to maintain a state in which they overlap each other.

Therefore, there is a cover structure of a type in which a front plate member and a back plate member are connected to each other by an easily bendable intermediate sheet material. However, with such a cover structure,
Since the front plate member and the back plate member must be separately provided and connected to each other by the intermediate sheet material, there is an inconvenience that the assembly work of the parts is inevitably required.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised in view of such inconvenience, and an object thereof is to reduce the number of parts and to use a front plate member and a back plate member during use. It is to provide a cover structure that can be held by hand with each outer surface combined with each other.

Another object of the present invention is to adopt a cover structure that allows the outer surfaces of the front plate member and the back plate member to be easily opened to a position where they are aligned substantially parallel to each other.

[0007]

In order to achieve the above object, the present invention is a front plate which is composed of a single resin sheet which can always maintain a planar shape and which can be opened and closed via a hinge portion. A main body including a member and a back plate member; and a holding member supported by the main body and capable of holding a closed posture in which the front plate member and the back plate member are combined, the hinge portion includes the front plate member and the back plate. The holding member is provided so as to be opened to a position where the outer surfaces of the members are aligned substantially parallel to each other, and the holding member is provided so as to be able to maintain the position where the outer surfaces of the front plate member and the back plate member are opposed to each other. ing. According to such a configuration, for example, when the cover structure is adopted for the paper clip, the front plate member may hang or get in the way when writing on the back plate member while holding the main body by hand. Instead, the outer surface of the front plate member and the outer surface of the back plate member can be comfortably held in the hand. Moreover, since the main body is made of one resin sheet, it is possible to simplify the main body without the conventional assembly work.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The holding member according to the present invention is composed of a stretchable band-shaped or string-shaped member, and the both ends of the band-shaped or string-shaped member are spread over two positions of a front plate member or a back plate member. It is preferable to adopt a configuration of being supported. In such a configuration, for example, when the strip-shaped or string-shaped member is supported at two positions on the back plate member, the strip-shaped or string-shaped member is hung around the outer surface of the front plate member to thereby remove the front plate member and the back plate. The closed posture of the member can be maintained. On the other hand, by opening the front plate member and the back plate member and hanging the strip-shaped or string-shaped member around the inner surface of the front plate, it is possible to maintain the position where the outer surfaces of the front plate member and the back plate member face each other. By doing so, it is possible to easily hold the front plate member and the back plate member in the closed postures and the respective outer surfaces in a combined position only by changing the position where the belt-shaped or string-shaped member is wound.

Further, it is possible to adopt a construction in which a writing instrument support portion is provided on the belt-shaped or cord-shaped member. According to this, the writing tool can be supported on the main body by using the strip-shaped or string-shaped member without using a separate member. For example, when the present invention is applied to a paper clip or a file, the writing tool and the paper are used. Can be associated with and held together.

Furthermore, the hinge portion may be configured to include a plurality of bending lines extending substantially parallel to each other, and these bending lines may be formed on each of the front and back surfaces. With such a configuration, when the front plate member and the back plate member are opened and closed, the hinge portion can be flexibly deformed by the action of the bending line. Accordingly, it is possible to smoothly perform the work of holding the outer surfaces of the front plate member and the back plate member at the positions facing each other while maintaining the planar shapes of the front plate member and the back plate member.

The clip 17 is a known clip which can hold the writing paper P by sandwiching the writing paper P (see FIG. 2) between the pressing member 32 and the base member 31.

Next, a method of using the paper clip 10 will be described.

When the front plate member 12 and the back plate member 13 are closed from the open state, from the state shown in FIG.
The front plate member 12 and the back plate member 13 are folded so that the inner surfaces thereof match. At this time, the two folded-back portions 1 near the center
When the hinge portion 11 is bent from 8 and a large amount of the writing paper P is sandwiched between the clips 17, as shown in FIG. 5 (A), the left and right widths of the folding lines 18 on the inner surface side are narrowed, and the outer surface is The left and right widths of the folding lines 18 on the side are expanded to form the hinge portion 11 in a substantially semi-circular shape in cross section. On the other hand, when the writing paper P is small, as shown in FIG. 5B, the hinge portion 11 is bent by the two folded-back portions 18 near the center. Then, as shown in FIG. 1, the belt-shaped member 25 positioned on the outer surface side of the back plate member 13
The front plate member 12 and the back plate member 13 are hung on the outer surface side of the front plate member 12 by pulling them while picking them up.
The closed posture is maintained.

Further, as shown in FIG. 6, the front plate member 1
After forcibly bending the outer surfaces of 2 and the back plate member 13 so as to match each other, the belt-shaped member 25 is hung around the inner surface side (lower surface side in FIG. 6) of the front plate member 12. At this time, the front plate member 12 tries to open in a direction away from the back plate member 13, but is regulated by the tension of the belt-shaped member 25, and the front plate member 1
