Description

[Detailed description of the invention] A. Field of industrial application The invention relates to a synthetic resin holder that removably holds the side edges of various papers, newspapers, pamphlets, etc. This issue concerns improvements to No. 111510.

(b) Prior Art The holder of the above-mentioned application had to be made thin and stylish in order to reduce the production cost as much as possible and increase the overall product price when actually manufactured.

C. Problems to be solved by the invention However, in actual production, the flexible connection part of the holder described above is press-formed at once from the same material as the front long piece and the back long piece. The rigidity of both long pieces and the flexibility of the connecting portion are contradictory to each other, and there is a certain limit to providing appropriate flexibility to the connecting portion.

Furthermore, if both elongated pieces are closed without holding paper, a gap is likely to be formed between the contacting inner surfaces of both elongated pieces, which increases toward the center, which is not desirable in terms of appearance.

D. Means for Solving the Problem Therefore, in the present invention, a large number of cuts are intermittently formed in the connecting portion to improve the flexibility of the connecting portion, while the inner surface where the two long pieces contact is In order to further improve the function, at least one long piece is provided with a bulging surface that gradually bulges out toward the center.
A measuring scale is attached along the holder body, and a plurality of protrusions are provided to prevent the U-shaped form from slipping.

Hereinafter, the gist of the present invention will be explained based on the embodiments shown in the drawings.

Embodiment FIG. 1 is a perspective view of the holder of the present invention in an open state, and FIG. 2 is a partially cutaway perspective view of the holder in its closed state.

In the drawings, 1 is a front side long piece, 2 is a back side long piece, and a U-shaped frame 4 with a pivot 3 on the back side long piece is fitted into the thin parts 1c and 2c as shown in the second figure. The surfaces of both long pieces 1 and 2 and the surface of the U-shaped frame 4 are made to be on the same plane. Both long pieces 1,
The flexible connecting portion 5 of No. 2 is provided with a large number of notches 6 as shown in the first figure to improve the flexibility of the connecting portion 5, and at least the inner surface central portion 1a of the front side long piece 1 or the back side long piece 2 or By gradually expanding 2a, the gap between the long pieces 1 and 2 described above is eliminated.

Furthermore, in the present invention, a measuring scale 7 is provided along the longitudinal direction of the holder, while a U-shaped frame 4 is provided with a measuring scale 7.
A large number of parallel protrusions 8 are raised on the surface thereof, and furthermore, a long groove 9 is bored in the center of the inner surface of the back long piece 2, and through holes 10, 10 for passing the string are provided.

F. Function In the holder of the present invention having the above configuration, when opening, the U-shaped frames 4, 4 are each rotated approximately 90 degrees around the shaft support 3 as shown in the first figure, and the front long piece 1 is opened. It is opened via the connecting part 5, the required paper etc. is inserted and closed, and the U-shaped frame 4 is rotatably fitted.

At this time, since the flexibility of the connecting part 5 is improved by the cuts 6, 6, etc., the opening and closing operation becomes smooth, and the clamping pressure against the paper is increased due to the extremely gradual bulging surface of the inner central part 1a or 2a. to ensure gripping, and both long pieces 1 and 2 when there is no paper.
This eliminates the gap between

G. Effect of the invention As described above, according to the invention, by providing the notches 6, 6... in the connecting portion 5, both the long pieces 1, 2
opening and closing more smoothly, and the bulging surface of the inner central part 1a or 2a can eliminate the gap that tends to occur between the central contact surfaces of both long pieces 1, 2, while the protrusions 8, 8... It has a number of advantages, such as facilitating the operation of the frame 4 and making it possible to carry out simple measuring by means of the measuring scale 7, and the practical benefits are significant.

Claims (1)

[Scope of utility model registration request] A U-shaped frame that controls the opening and closing of both long pieces of the holder main body, which is composed of a front long piece and a back long piece that can be opened and closed via a flexible connection part, is pivotally supported at both ends of the holder main body, and the front side and the back side are In a holder in which a thin part is formed at the end of the long piece so that the U-shaped surface and the surface of each long piece become flat surfaces when the U-shaped frame is fitted, the flexible connecting part In addition to drilling a large number of notches, a bulging surface is gradually provided at least on the front side or the back side long piece, or at the center of the inner surface of both long pieces, to fill the gap that occurs between the two long pieces in the closed state with no object to be held. The holder is characterized in that a measuring scale is provided along the length of the holder body, and a protrusion for preventing slipping is provided on the U-shaped frame.
