Description

The present invention relates to a ball clip device, and more particularly to a ball grip device in which there is no friction between a paper material and a wall when sandwiched.

Patent Document 1 discloses a paper clip that sandwiches paper between a sphere and a wall. Specifically, the paper is sandwiched between the sphere and the wall, and the paper is pressed horizontally against the wall by the sphere on the inclined surface. In this structure, when the paper is inserted into the paper clip, the friction between the paper and the wall is large and the paper is easily deformed. Further, the force of the sphere pushing the paper is as small as about 4.3 g when the angle of the inclined surface is 60 degrees and the force of pushing the paper against the wall is 10 g. The thickness of the paper is 0.07 mm for thin paper and about 0.25 mm for postcards. Japanese paper that is hard to tear has a thickness of about 0.15 mm. Therefore, a structure that does not cause friction with the wall when inserting the paper is desired. Further, a structure capable of increasing the pressing force even with the same sphere is desired.

An object of the present invention is to provide a ball grip device that does not come into contact with a wall when inserted and can increase the pressing force of a ball that presses a paper material.

The ball clip device according to the present invention has a plurality of block bodies having a vertical surface formed on one side and an inclined surface formed on the other side, arranged in one direction, and the upper portions connected by rail members, and the block body. A lower support plate attached to the bottom of the block body, a first ball arranged between the block body and the block body and supported in contact with the vertical surface and the lower support plate, and an arrangement between the block body and the block body. The second ball, one side of which is in contact with the outer peripheral surface of the first ball and the other side of which is in contact with the inclined surface to be supported, and the lower support plate are separated from each other, and a paper formed on the lower portion of the block body. A paper insertion port is provided, and a line (m) connecting the center of the first ball and the center of the second ball is arranged so as to face diagonally downward, and paper inserted from the insertion port. The material is sandwiched between the first ball and the second ball, and is held by a pressing force of the second ball in an obliquely downward direction.

Enclosing plates are provided on both side surfaces of the block body, and the surrounding plates prevent the first ball and the second ball from falling off, and the paper material can be inserted between the first ball and the second ball. It is characterized in that they are separated from each other so as to be.

The first ball and the second ball are glass balls.

According to the ball clip device of the present invention
(1) Since the structure is such that the paper material is sandwiched between the first ball and the second ball, the paper material does not come into contact with the wall, and deformation and wrinkles of the paper material at the time of insertion can be prevented.
(2) The second ball is brought into contact with the outer peripheral surface of the first ball at an angle, and the line (m) connecting the center of the first ball and the center of the second ball is arranged so as to face diagonally downward. The pressing force with which the second ball presses the paper material can be made larger than when the paper material is pressed horizontally against the vertical wall.
(3) As the plurality of block bodies, a block body having a vertical surface formed on one side and an inclined surface formed on the other side can be commonly used.
(4) Since a plurality of block bodies are linearly attached to the rail member, a large number of paper materials can be sandwiched and suspended. It can handle the number of paper materials to be hung.

Since the surrounding plates are provided on both side surfaces of the block body, it is possible to prevent the first ball and the second ball from falling off from the side surface. It is easier to manufacture than when a groove is formed in the block body to hold the ball. For example, even if the diameter of the ball is changed, it can be used as it is, depending on the size of the internal space.

Since the first ball and the second ball are made of glass balls, they have durability and chemical resistance as compared with plastic. There is no concern about corrosion compared to stainless steel balls. The glass ball is lighter than the steel ball, and where the diameter of the second ball is large, it is possible to prevent the size of the glass ball from increasing due to the pressing force pointing diagonally downward.

Hereinafter, the ball clip device of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of the ball clip device 100 according to the present invention. The ball clip device 100 includes a plurality of block bodies 5 whose upper portions are connected by a rail member 8, first balls 1 and second balls 2 arranged between the two block bodies 5, and a lower support plate 4. Consists of including. The block body 5 has a vertical surface 7 formed on one side and an inclined surface 6 formed on the other side. Further, the block bodies 5 are arranged so as to face one direction, and the vertical surface 7 and the inclined surface 6 are arranged so as to face each other. At least two block bodies 5 are required, and a plurality of block bodies 5 are arranged.

The first ball 1 is arranged between the block bodies 5 and 5, and is supported in contact with the vertical surface 7 of the block body 5 and the upper surface of the lower support plate 4. The second ball 2 is arranged between the block bodies 5 and 5, and one side is in contact with the outer peripheral surface of the first ball 1 and the other side is in contact with and supported by the inclined surface 6 of the block body 5. Since the surrounding plates 3 are provided on both front and rear surfaces of the block body 5, the first ball 1 and the second ball 2 are prevented from falling to the outside. The space between the blocks 5 and 5 is the place where the paper material 10 is sandwiched. Therefore, the lower support plates 4 are separated from each other in the left-right direction, and an insertion port 9 for the paper material 10 is formed in the lower portion of the block body 5. The paper material 10 inserted from the insertion port 9 is sandwiched between the first ball 1 and the second ball 2 and is held in a suspended state.

FIG. 2 is a cross-sectional view (plan view) taken along the line AA of FIG. The surrounding plate 3 is also separated from each other in the left-right direction, and the inserted paper material 10 can be inserted to the upper part. In this embodiment, the diameter of the second ball 2 is larger than the diameter of the first ball 1. Specifically, the second ball 2 is a glass ball having a diameter of 25 mm and a weight of 19.4 g, and the first ball 1 is a glass ball having a diameter of 17 mm and a weight of 6.5 g. The inserted paper material 10 is sandwiched between the first ball 1 and the second ball 2.

FIG. 3 is a diagram showing an example of using the ball clip device 100 according to the present invention. A plurality of block bodies 5 are attached to the two rail members 8, and sandwich the upper left and right two places of the paper material 10. The ball clip device 100 can be used to suspend Japanese paper and accelerate drying after dyeing (prints, etc.).

FIG. 4 is an explanatory diagram showing the movements of the first ball 1 and the second ball 2. (A) shows the case where the paper material 10 is inserted, and (B) shows the case where the paper material 10 is removed. As shown in (A), the paper material 10 is inserted into the insertion port 9, further pushed up, the paper material 10 is sandwiched between the first ball 1 and the second ball 2, and the second ball 2 is the thickness of the paper material 10. , 0.07 to 0.25 mm is raised to bring the paper material 10 into a suspended state. In the suspended state, since the second ball 2 is on the inclined surface 6, the paper material 10 is pressed against the first ball 1 by the weight of the second ball 2. The bottom of the second ball 2 is in a state of being separated from the upper surface of the lower support plate 4 when the paper material 10 is not inserted. As shown in (B), when the paper material 10 is pulled out, the paper material 10 is pulled out downward. If there is a certain pulling force, the second ball 2 rotates by friction, so that the paper material 10 can be pulled out.

FIG. 5 is an explanatory diagram of the pressing force when the paper material 10 is sandwiched. Let F be the weight of the second ball 2, let θ be the angle of the inclined surface 6, and let θ'be the angle formed by the line m connecting the center of the first ball 1 and the center of the second ball 2 with the horizontal line. The second ball 2 holds the paper material 10 by a pressing force (Fa) in the diagonally downward direction (direction indicated by the line m). The second ball 2 presses the inclined surface 6 with a pressing force (Fb). Assuming that the diameter of the first ball 1 is d1 and the diameter of the second ball 2 is d2, the line m can be directed diagonally downward by setting the length L to be smaller than d1 + d2. Even if d1 and d2 have the same diameter, if the length L is set to be smaller than d1 + d2, the line m can be directed diagonally downward. Even if the second ball 2 has the same diameter as the first ball 1, it can be arranged in such a positional relationship.

FIG. 6 is a diagram showing another usage example of the ball clip device 100 according to the present invention.
The number of rail members 8 may be one, and the paper material 10 can be curved to sandwich the upper left and right two places.

According to this embodiment, (1) the paper material does not come into contact with the wall, so that deformation and wrinkles of the paper material can be prevented. (2) Since the paper material is sandwiched between the first ball and the second ball and the second ball presses the paper material diagonally downward, the pressing force can be further increased even for the same ball. (3) Since a plurality of block bodies are attached to the rail member, a large number of paper materials can be sandwiched and hung. (4) A glass ball (marble) having chemical resistance can be used for the first ball and the second ball. It plays an effect such as.

The present invention is suitable as a ball clip device for suspending a large number of paper materials.
