ADVANTAGE OF THE INVENTION According to this invention, there exist the following effects.
(1) A clamping member in which two leaf springs having arcuate cross-sections that are outwardly convex are opposed to each other with their concave surfaces facing each other, and both ends of the leaf springs are respectively connected to hinges; Both ends of the base plate are placed in the vicinity of the hinge, one leaf spring and the base plate are integrally provided, and the one leaf spring is integrated with the base plate. The provided base plate and the remaining one leaf spring are bent outward by pressing both ends of the clamping member, and the base plate provided integrally with the one leaf spring in the open state. An object to be clamped is placed between the side and the remaining leaf spring, and by releasing the pressure, it can be restored to a straight line and closed. Since the paper clip is characterized by being sandwiched, the thickness from the base plate to the clipping member is not large, and it is possible to reduce the bulkiness when the paper is to be stored in, for example, a chest pocket. There is an effect that it can be made into a paper clip that is not bulky when it is to be stored in a breast pocket or the like (effect 1-1).
In addition, there is an effect that it is possible to make a paper clip that can be reduced in weight because it is approximately lightweight (effect 1-2).
In addition, since it is flat as a whole, it is less likely to be damaged. To reduce the risk of damage to the paper clip, and to reduce the risk of damage to the paper clip when the paper clip is stepped on by a foot or the like. To reduce the risk of damage to a paper clip when the paper clip falls on a floor or the like, and to reduce the risk of damage to the paper clip when the paper clip is stepped on by a foot or the like. (Effect 1-3).
Moreover, materials such as leaf springs, hinges, etc., can be used on the market. Since it can be processed by technology, it is relatively easy to process and can reduce the processing cost.In addition, since there is no need for molding, etc., processing is relatively easy and the processing cost can be reduced. There is an effect that it can be done (effect 1-4-1).
In addition, for example, in the central part of the base plate, it is easy to sandwich a few sheets of paper used in a commercially available memo pad or the like between the remaining leaf spring and the base plate. If it is a piece of paper, it is easy to sandwich one sheet. It is possible to hold a piece of paper used in a commercially available memo pad or the like at the relevant portion, and the tips of two eyelets or the like or hinges that are fixed to the one end of the remaining one leaf spring and the hinge. A part of the sheet and the paper come into contact with each other. 5).
Also, for example, at one of both ends of the leaf spring, if the gap between the leaf springs is not large, it may be a stack of several sheets of paper used in a commercially available notepad or the like, or a single sheet of thick paper. For example, the tips of two eyelets or a part of the hinge, which are fixed to the one end of the leaf spring and the hinge, abut against the back surface of the paper, and At the same time, the tip of the two eyelets or a part of the hinge, to which the other end of the leaf spring and the hinge are fixed, abuts against the surface of the paper, and by abutting, It is sandwiched and has a certain clamping force, and there is an effect that several sheets of paper used in a commercially available memo pad or the like, or a single sheet of thick paper, does not fall off (effect 2 -1).
(2) The leaf spring on one side and the base plate are integrally provided, and the paper clip is characterized in that the leaf spring on the one side and the base plate are fixed together. , one end of one of the leaf springs and the base plate are arranged in this order, and fixed with eyelets. Since it can be processed by a conventional technique, the processing is relatively easy, and the processing cost can be reduced (effect 1-4-2).
(3) Since the paper holder is characterized in that the base plate is inserted between the concave surfaces of the leaf springs that are opposed to each other, it can be bent outward and opened, or linearly. Even when they are restored to the original position and closed, there is an effect that each other hardly interferes with the movement of the other and that there is little movement that restrains the other (effect 1-6).
(4) The paper holder is characterized in that a holding piece for holding down the object to be held closed by releasing the pressure is provided on the side of the base plate fixed to the one of the leaf springs. For example, the hinge, one end of one of the leaf springs, the base plate, and the tip of the eyelet to which the pressing piece is fixed, or a part of the pressing piece, and the paper abut. , there is an effect that it is clamped by abutting, and a constant clamping force is improved (effect 3-1).
Further, for example, the central portion of the base plate and the tip of the eyelet or the like to which the restraining piece is fixed or a part of the restraining piece and the paper come into contact with each other. There is an effect that the clamping force is improved (effect 4-1).

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below based on the accompanying drawings, but the scope of the present invention is not limited to the embodiments described below. The effects are described so as to correspond to each of the problems described in the above section (Problems to be Solved by the Invention). The number corresponding to the number attached to each task is described. For example, the effect corresponding to (problem 1-1) in the section (problems to be solved by the invention) is described as (effect 1-1). Also, for example, the first number "1" in (Effect 1-1) represents Example 1, and the subsequent numbers represent serial numbers.

Each example, which is one embodiment of the present invention, will be described. A part of the drawing will be explained. 4, 5, 8, and 9 are cross-sectional views of the vicinity of the center, which is not fixed by eyelets and caulking.

Next, in the specification, the meanings of the terms described will be supplemented. I will write about "stopping". The term 'hold' is not written in Kojien. As for "stopping", there is a description of holding down according to Patent Technical Glossary 2nd edition (Nikkan Kogyo Shimbun).

Next, the paper clip (1), which is Example 1, will be described. The paper holder (1), which is the first embodiment, is constructed as follows in FIGS. 1 to 5. FIG. 4 and 5, two leaf springs (3A) and (3B) whose cross sections are curved in arcuate shapes (2A) and (2B) so as to project outward (arrow G1) (arrow G2) With the concave surfaces (4A) and (4B) facing each other, in FIGS. 6A) and (6B) as clamping members (7) respectively connected. It also comprises a base plate (8) on which the object to be held (11) is placed. Both ends (9A) (9B) of the base plate (8) are arranged near the respective hinges (6A) (6B). One leaf spring (3A) and a base plate (8) are integrally provided.

A part of the base plate (8) will be additionally explained. The base plate (8) of Example 1 is a thin plate-shaped soft synthetic resin, and is made of polypropylene (PP). A flexible material is used. Alternatively, the following may be done. You may form with synthetic resins, such as polyvinyl chloride (PVC), polyethylene (PE), polyethylene terephthalate (PET), and nylon. Alternatively, it may be elastic or the like. Moreover, you may process the multilayer sheet containing these. However, the material is not limited to this, and other materials may be selected as appropriate. For example, it may be metal. In addition, it is preferable to be able to bend and restore after bending. The base plate (8) is flat and planar with a thickness of about 0.5 mm. The length of the base plate (8) is about 110 mm in the longitudinal direction of the leaf springs (3A) (3B), and about 120 mm in the lateral direction of the leaf springs (3A) (3B). , A4 size vertically folded to 1/6 size paper can be sandwiched between them. Note that the length and thickness of the base plate (8) are different depending on the material of the base plate (8), and the base plate (8) may be provided as appropriate. Also, the plate thickness may be determined in consideration of deformation due to long-term use.

In Example 1, both ends (9A) and (9B) of the base plate (8) are arranged near the hinges (6A) and (6B). More specifically, the hinge (6A) and the base plate (8 ) is aligned with the edge (9A) of the base plate (8), and the hinge (6B) is aligned with the edge (9B) of the base plate (8). In other words, it can also be stated as follows. The concave surfaces (4A) and (4B) of two leaf springs (3A) and (3B) whose cross sections are curved in circular arcs (2A) and (2B) so as to be convex outward (arrow G1) (arrow G2) are With respect to the clamping member (7) in which the opposite ends (5A) (5B) (5C) (5D) of the leaf springs (3A) (3B) are respectively connected to hinges (6A) (6B), The opposite ends (5A) ( 5B), (5C) and (5D) can also be described as clamping members (7) connected to hinges (6A) and (6B) arranged on the left and right sides, respectively.

Further, the paper clip (1) of Example 1 is constructed as follows. One leaf spring (3A) and the base plate (8) are fixed.

A part of the fixation will be explained supplementarily. In FIG. 2, for example, a holding member (7) in which one end (19A) of both ends (5A) and (5B) of one leaf spring (3A) is connected to a hinge (6A) is end (19A) and hinge (6A) are fixed by eyelet (12A). At the same time, the one end (19A) and the base plate (8) are fixed together by eyelets (12A). That is, from the outside, the hinge (6A), one end (19A) of the one leaf spring (3A), and the base plate (8) are arranged in this order, and fixed by the eyelet (12A) to be integrally provided. There is. In addition, in FIG. 2, some of the symbols are omitted because it would be crowded if the symbols were further described in the figure, but the eyelets (12AA) are provided below the eyelets (12A) and are fixed in the same way. There are two vertical eyelets (12A) (12AA). Separately, one leaf spring (3A) and the base plate (8) are fixed by caulking (13A). Although the eyelet (12A) is a single-sided eyelet, it may be a double-sided eyelet. Crimping or rivets may be used instead of the eyelets (12A). Further, instead of the caulking (13A), eyelets or rivets may be used for fixation. Similarly, with respect to the clamping member (7) in which the remaining one end (19B) of both ends (5A) and (5B) of one leaf spring (3A) is connected to the hinge (6B), the remaining one end (19B) and hinge (6B) are fixed by eyelet (12B). At the same time, the remaining one end (19B) and the base plate (8) are fixed together by means of eyelets (12B). That is, from the outside, the hinge (6B), the remaining one end (19B) of the one leaf spring (3A), and the base plate (8) are arranged in this order, and are fixed by the eyelet (12B) to be integrated. It is provided. Similarly, in FIG. 2 , some of the symbols are omitted because the symbols would be too crowded if they were added to the drawing. There are two vertical eyelets (12B) and (12BB). Separately, one leaf spring (3A) and the base plate (8) are fixed by caulking (13B). Similarly, the clamping member (7) is similarly connected to hinges (6A) and (6B) at both ends (5C) and (5D) of the remaining leaf spring (3B). In FIG. 2, some of the symbols are omitted to avoid confusion if the symbols are further described in the figure. 19C) and the hinge (6A) are fixed by eyelets. The remaining one end (19D) of both ends (5C) and (5D) of the remaining leaf spring (3B) and the hinge (6B) are fixed by an eyelet.

Alternatively, the following may be done. Although not shown in particular, for example, in FIG. 2, the crimp (13A) may be moved slightly upward, a new crimp may be provided below the row, and two crimps (13A) may be formed vertically. good. The leaf spring (3A) on one side and the base plate (8) are fixed by caulking (13A). etc. may be attached and provided integrally. Alternatively, an adhesive may be used.

Further, the paper holder (1), which is the first embodiment, may be modified as follows. Although not shown in particular, for example, with respect to the clamping member (7) in which one end (19A) of both ends (5A) and (5B) of one leaf spring (3A) is connected to a hinge (6A), the one and the hinge (6A) are fixed by the eyelet (12A), but the one end (19A) and the base plate (8) are not fixed by the eyelet (12A). . That is, even if a commercially available clamping member in which the leaf spring and the hinge are already connected by eyelets is purchased, and then, for example, one of the leaf springs (3A) and the base plate (8) are fixed by caulking. good. Further, instead of caulking, eyelets or rivets may be used.

Next, the action of the paper holder (1), which is the first embodiment, will be described. 1 to 5, the base plate (8) integrally provided with the leaf spring (3A) on one side and the leaf spring (3B) on the other side are connected to both ends ( 10A) and (10B) are bent outward (arrow G1) (arrow G2) to open.

In this case, the base plate (8) integrally provided with the one leaf spring (3A) opens outward (arrow G1), and the other leaf spring (3B) opens outward (arrow G2).

An object to be clamped (11) is placed between the base plate (8) integrally provided with one leaf spring (3A) in the open state and the other leaf spring (3B). . By placing it and releasing the pressure, it can be restored to a straight line and closed. By closing, the placed object to be clamped (11) is pinched.

Further, the operation of the paper holder (1), which is the first embodiment, can be partially rephrased as follows. 1 to 5, the base plate (8) fixed to one of the leaf springs (3A) and the remaining one of the leaf springs (3B) are attached to both ends (10A) of the clamping member (7). By pressing (10B), it bends outward (arrow G1) (arrow G2) and opens. An object to be clamped (11) is placed between the base plate (8) fixed to one of the leaf springs (3A) in the open state and the other one of the leaf springs (3B).

Further, the paper clip (1) of Example 1 is constructed as follows. In FIGS. 4 and 5, the base plate (8) is inserted between the concave surfaces (4A) and (4B) of the leaf springs (3A) and (3B) facing each other. One of the leaf springs (3A) and the base plate (8) are fixed together. A spring (3A) and a base plate (8) are fixed. In addition, the part to be held (11) is placed between the base plate (8) side fixed to one leaf spring (3A) and the other leaf spring (3B). Specifically, it is between the base plate (8) on the side of the base plate (8) fixed to one of the leaf springs (3A) and the concave surface (4B) of the other one of the leaf springs (3B).

The action of the paper clip (1), which is the first embodiment, is supplemented. By releasing the pressure, it can be restored to a straight line and closed. Specifically, it is fixed to one of the leaf springs (3A) that has been bent outward (arrow G1) (arrow G2) and opened. By releasing the pressure, the base plate (8) and the remaining one leaf spring (3B) return inward (arrow U1) (arrow U2), restore linearly, and close. is made possible.

Next, leaf springs (3A) and (3B), hinges (6A) and (6B), etc. will be partially supplemented. Each of the plate springs (3A) and (3B) of Example 1 has a plate thickness of about 0.1 mm. Also, the concave surfaces (4A) and (4B) of the two leaf springs (3A) (3B) are opposed to each other, and both ends (5A) (5B) (5C) (5A) (5B) (5C) ( 5D) linearly closes the clamping member (7) connected to hinges (6A) and (6B), and two leaf springs (3A) (3B) and a base plate (8). are not integrally provided, that is, the maximum thickness of each of the hinges (6A) (6B) in a state without the base plate (8) is about 3 mm. Further, as described above, the plate thickness of the base plate (8) is about 0.5 mm. Therefore, the hinge (6A) in a state in which the holding member (7) is linearly closed and the two leaf springs (3A) (3B) and the base plate (8) are integrally provided. The thickness of each maximum portion of (6B) is approximately 3.5 mm. That is, the maximum thickness of the entire paper clip (1) of Example 1 is about 3.5 mm. The total weight of the paper clamp (1) of Example 1 in which the two leaf springs (3A) and (3B) and the base plate (8) are integrated is about 15 g.

A part of the object to be held (11) will be additionally explained. The object to be held (11) is mainly made of paper, but it may be made of sheet-shaped synthetic resin. However, the material is not limited to this, and other materials may be selected as appropriate.

Further, the paper clip (1) of Example 1 is constructed as follows. FIG. 14 is a top view of the paper clip (1) in FIG. 1 in a closed state restored to a straight line. In FIG. 14, for example, at the central portion (14) of the base plate (8), a gap (23) is generated between the remaining leaf spring (3B) and the base plate (8). Therefore, for example, it is not easy to pinch one sheet of paper used in a commercially available memo pad or the like at the relevant portion, but it is easy to pinch if several sheets of paper are piled up. Also, if it is a thick paper, it is easy to sandwich one sheet. Further, for example, at one (9A) of both ends (9A) and (9B) of the base plate (8), a gap is generated between the remaining leaf spring (3B) and the base plate (8). not. Therefore, for example, a sheet of paper used for a commercially available memo pad or the like can be sandwiched at the relevant location. Specifically, the tips of two eyelets or the like or a part of the hinge (6A) that is fixed to the one end (5C) of the remaining leaf spring (3B) and the hinge (6A), abut against the paper. By abutting against each other, the paper is pinched and has a certain pinching force, and there is an effect that even a single sheet of paper does not come off (effect 1-5).

Next, the circumstances leading to the invention will be described. A clamping member in which two leaf springs having a cross section curved in an arcuate shape so as to protrude outward are opposed to each other with their concave surfaces facing each other, and both ends of the leaf springs are connected to hinges are generally commercially available. circulates effectively. Regarding the central portion of the leaf springs, in which the concave surfaces of the clamping member are opposed to each other, there is a gap between the leaf springs when they are restored to a straight line and closed. Even if one tried to put one sheet in the gap, it was not easy to do so because the gap was larger. In addition, in the vicinity of both ends of the leaf spring where the concave surfaces of the sandwiching members are opposed to each other, although the gap between the leaf springs is small, it is possible to sandwich several stacked sheets of paper or one sheet of thick paper. However, even if a sheet of paper used in a commercially available memo pad or the like is to be sandwiched between the gaps, the gap is too large to allow it to be sandwiched. Comparing the gaps between the leaf springs in the vicinity of both ends of the holding member and the center of the leaf spring, the gap between the leaf springs in the vicinity of both ends is smaller than that in the center. Focusing on this point, the paper clip (1) of the first embodiment fills the gap by combining the leaf springs (3A) and (3B) with the base plate (8), so that even one sheet of paper can be It can be sandwiched. This has led to the effect (effect 1-5 above) that a certain holding force is provided and even a single sheet of paper does not come off. The present invention achieves the remarkable effects as described above. It is believed that the present invention is neither readily conceivable nor easily accomplished by those skilled in the art.

Next, the effect of Example 1 is added. Next, in order to describe the above-mentioned "problem to be solved by the invention" and the corresponding effect of the first embodiment, the "problem to be solved by the invention" will be reprinted below, although it is redundant.

The first subject is described. Patent Literature 1 has a problem that the thickness from the base plate to the clamping member is large and, for example, it becomes bulky when trying to store it in a breast pocket or the like. It is an object of the present invention to solve the above-mentioned problems and to provide a paper clip that is less bulky when it is to be stored in a breast pocket or the like (problem 1-1).

The effects for the first problem will be described. As described above, the paper clip (1), which is the first embodiment, consists of two leaf springs (3A) (3B) with their concave surfaces (4A) and (4B) facing each other. Both ends (5A), (5B), (5C), and (5D) of (3A) and (3B) are connected to hinges (6A) and (6B), respectively. The maximum thickness of each of the hinges (6A) and (6B) in which the leaf spring (3A) and the base plate (8) are integrally provided is about 3.5 mm. Therefore, the thickness from the base plate to the clamping member is not large, and it is possible to reduce the bulkiness of the device when it is to be stored in a breast pocket or the like. There is an effect that it can be made into a paper clip that is not bulky when it is to be stored in a breast pocket or the like (effect 1-1).

Next, the second subject will be described. Patent document 1 includes "a base plate," "a clamping member," and "a biasing member," and further, "the base plate" "comprising a pair of bearing members," "the clamping member," and "a pair of pivot shafts." There is a problem that it cannot necessarily be said to be lightweight because it includes a portion,” “further”, “the base plate”, and “a storage portion is provided”. It is an object of the present invention to solve the above problems and to provide a paper clip that can be further reduced in weight (problem 1-2).

The effect on the second problem will be described. As described above, the paper holder (1), which is the first embodiment, is the holding member (7) in which the plate spring (3A) on one side and the base plate (8) are integrally provided. The total weight of the paper clip (1) of Example 1 is about 15 g. In other words, unlike the form of Patent Document 1, the "base plate", "holding member", and "biasing member" of Patent Document 1 are not included. First of all, the ``clamping member'' does not ``include a pair of pivot shafts'', and ``further'', ``the base plate'' does not ``provide a storage part'', so it is approximately lighter than Patent Document 1. It has become. There is an effect that it is possible to make a paper clip that can be reduced in weight (effect 1-2).

Next, the third subject will be described. Patent document 1 includes "a base plate," "a clamping member," and "a biasing member," and further, "the base plate" "comprising a pair of bearing members," "the clamping member," and "a pair of pivot shafts." "Including the part", "Furthermore", "The base plate" and "A storage part are provided", so when the scissors fall on the floor, etc. In addition, when the scissors are stepped on with a foot or the like, there is a risk that a part of the scissors mainly at the relevant portion may be damaged. By solving the above-mentioned problem, when the scissors fall on the floor surface, etc., the possibility that a part of the scissors, mainly the relevant part, will be damaged is reduced, and the scissors fall on the feet, etc. It is an object of the present invention to provide a paper scissor that reduces the risk of damage to a part of the scissor mainly at that location when stepped on by a user (problem 1-3).

The effect on the third problem will be described. As described above, the base plate (8) of Example 1 is about 0.5 mm thick, flat, planar, and made of thin soft synthetic resin. With the concave surfaces (4A) and (4B) of the two leaf springs (3A) and (3B) opposed to each other, both ends (5A) (5B) (5C) (5D) of the leaf springs (3A) (3B) The clamping member (7) connected to the hinges (6A) and (6B) is linearly closed, and the plate spring (3A) on one side and the base plate (8) are integrally provided. The maximum thickness of each of the state hinges (6A) and (6B) is approximately 3.5 mm. Since the paper clip (1) of Example 1 is flat as a whole, it is less likely to be damaged. In addition, the leaf springs (3A) (3B) and the hinges (6A) (6B) are also made of metal and are less likely to be damaged. The base plate (8) is made of polypropylene (PP) and is made of a flexible material. Therefore, unlike the form of Patent Document 1, the "base plate", the "holding member", and the "biasing member" of Patent Document 1 are not included, and the "base plate" and "a pair of bearing members are included. First of all, the ``clamping member'' does not ``include a pair of pivots,'' and ``further'', ``the base plate'' does not ``provide a storage part,'' so that the paper clip falls onto the floor, etc. In this case, the paper clip is less likely to be damaged, and when the paper clip is stepped on by a foot or the like, the paper clip is less likely to be damaged. To reduce the risk of damage to a paper clip when the paper clip falls on a floor or the like, and to reduce the risk of damage to the paper clip when the paper clip is stepped on by a foot or the like. (Effect 1-3).

Next, the fourth subject will be described. Patent document 1 includes "a base plate," "a clamping member," and "a biasing member," and further, "the base plate" "comprising a pair of bearing members," "the clamping member," and "a pair of pivot shafts." There is a problem that the processing is not relatively easy because of the fact that it includes a portion,” “further”, “the base plate”, and “a storage portion is provided”, and there is concern about an increase in cost. It is an object of the present invention to solve the above problems and to provide a paper holder that can be processed relatively easily and at a reduced processing cost (problem 1-4).

The effect on the fourth problem will be described. As described above, the base plate (8) of Example 1 is flat and has a planar shape, does not require molding, etc., is relatively easy to process, and can reduce processing costs. . The base plate (8) has a plate thickness of about 0.5 mm and is made of a thin plate of soft synthetic resin. Materials such as leaf springs (3A) and (3B) and hinges (6A) and (6B) can be commercially available. With the concave surfaces (4A) and (4B) of the two leaf springs (3A) and (3B) opposed to each other, both ends (5A) (5B) (5C) (5D) of the leaf springs (3A) (3B) The clamping member (7) connected to the hinges (6A) and (6B) can also be processed by conventional techniques, so that the processing is relatively easy and the processing cost can be reduced. Further, for example, regarding the clamping member (7) in which one end (19A) of both ends (5A) and (5B) of one leaf spring (3A) is connected to a hinge (6A), the one end (19A) and hinge (6A) are fixed by eyelet (12A). At the same time, the one end (19A) and the base plate (8) are fixed together by eyelets (12A). That is, from the outside, the hinge (6A), one end (19A) of the one leaf spring (3A), and the base plate (8) are arranged in this order, and fixed by the eyelet (12A) to be integrally provided. There is. Separately, one leaf spring (3A) and the base plate (8) are fixed by caulking (13A). Since fixing can also be processed by conventional techniques, processing is relatively easy and processing costs can be reduced.

Therefore, unlike the form of Patent Document 1, the "base plate", the "holding member", and the "biasing member" of Patent Document 1 are not included, and the "base plate" and "a pair of bearing members are included. First of all, the ``clamping member'' does not ``include a pair of pivot shafts'', and ``further'', ``the base plate'' does not ``provide a storage part'', so that the processing is relatively easy and the processing cost is low. There is an effect that the paper clip can be reduced (effect 1-4-1). Alternatively, for example, a hinge, one end of one of the leaf springs, and the base plate may be arranged in this order and secured by eyelets, and the one leaf spring and the base plate may be separately secured by caulking. Therefore, the fixation can be processed by the conventional technology, so that the processing is relatively easy and the processing cost can be reduced (effect 1-4-2).

Next, the paper clip (1a), which is Example 2, will be described. 6 to 9, the paper holder (1a), which is the second embodiment, is constructed as follows. In FIGS. 8 and 9, two leaf springs (3Aa) and (3Ba) whose cross sections are curved in arcs (2Aa) (2Ba) so as to project outward (arrow G1) (arrow G2) are shown. With the concave surfaces (4Aa) and (4Ba) opposed to each other, in FIGS. 6Aa) and (6Ba) as clamping members (7a) respectively connected. It also comprises a base plate (8a) on which the object to be held (11) is placed. Both ends (9Aa) (9Ba) of the base plate (8a) are arranged near the respective hinges (6Aa) (6Ba). One leaf spring (3Aa) and a base plate (8a) are integrally provided. One leaf spring (3Aa) and the base plate (8a) are fixed.

Next, the action of the paper clip (1a), which is Example 2, will be described. The operation of the second embodiment is approximately the same as that of the paper clip (1) of the first embodiment. In FIGS. 6 and 7, the base plate (8a) integrally provided with the leaf spring (3Aa) on one side and the leaf spring (3Ba) on the other side are connected to both ends ( 10Aa) and (10Ba) are bent outward (arrow G1) (arrow G2) to open. In the open state, the object to be clamped (11) is placed between the base plate (8a) provided integrally with one of the leaf springs (3Aa) and the other one of the leaf springs (3Ba). . By putting it on and releasing the pressure, it can be restored in a straight line and closed. By closing, the placed object to be clamped (11) is pinched.

The paper holder (1a) of Example 2 is constructed as follows. One of the leaf springs (3Aa) and the base plate (8a) are fixed together. A spring (3Aa) and a base plate (8a) are fixed. In addition, the part to be held (11) is placed between the base plate (8a) side fixed to one leaf spring (3Aa) and the other leaf spring (3Ba). Specifically, it is between the plate spring (3Aa) on the side of the base plate (8a) fixed to one of the plate springs (3Aa) and the concave surface (4Ba) of the other plate spring (3Ba).

In addition, although the base plate (8a) provided integrally with one leaf spring (3Aa) is described as "side", in Example 2, this is integrally provided with one leaf spring (3Aa). The base plate (8a) is not described, but the leaf spring (3Aa) on the side of the base plate (8a) provided integrally with one of the leaf springs (3Aa) is described. Therefore, it is described as "side". On the other hand, in Example 1, the "side" of the base plate (8) provided integrally with one of the leaf springs (3A) is described, but this means that the base plate (8) is provided integrally with one of the leaf springs (3A). The leaf spring (3A) on the side of the base plate (8) is not described, but the base plate (8) provided integrally with one of the leaf springs (3A) is described. Therefore, this is also described as "side". In this way, the "side" of the base plate integrally provided on one leaf spring is connected to the base plate (8) provided integrally with the one leaf spring (3A) or to the one leaf spring (3Aa). It indicates the plate spring (3Aa) on the side of the base plate (8a) provided integrally.

The paper holder (1a) of Example 2 is constructed as follows. In FIG. 6, for example, at one (5Aa) (5Ca) of both ends (5Aa) (5Ba) (5Ca) (5Da) of leaf springs (3Aa) (3Ba), leaf springs (3Aa) (3Ba) If the gap between them is not large and several sheets of paper used in a memo pad on the market are piled up or one sheet of thick paper is easily sandwiched. Specifically, for example, the tips of two eyelets or the like or a part of the hinge (6Aa) and the paper , and at the same time, the tips of two eyelets or the like or the hinge ( A portion of 6Aa) and the surface of the paper abut. By contacting, it is clamped and has a certain clamping force, and the effect that several sheets of paper used for commercially available memo pads or the like, or a thick sheet of paper will not fall off. (Effect 2-1).

Next, a part of the paper holder (1), which is the first embodiment, will be additionally described. FIG. 12 shows that the leaf spring (3A) on one side and the base plate (8) before being integrally provided with the leaf spring (3A) on one side are pushed outward ( It is an explanatory diagram viewed from above in an open state bent in the direction of arrow G1). The remaining leaf spring (3B) is omitted for the sake of explanation. In other words, in FIG. 12, the leaf spring (3A) on one side and the base plate (8) are not provided integrally, but are made independent and free, and are partially viewed from above. There is. As shown in FIG. 12, in a state in which the one leaf spring (3A) and the base plate (8) are not provided integrally but are independent and free, both ends of the clamping member are pressed to move outward. When the base plate (8) is bent (arrow G1) and opened, a gap (20) is formed between one leaf spring (3A) and the base plate (8) at the central portion (14) of the base plate (8). It is known to occur. When both ends of the clamping member are pressed, the base plate (8) bends outward (arrow G1) at a constant speed and opens, while the leaf spring (3A) on one side At the timing, it quickly bends outward (arrow G1) and opens. When the plate spring (3A) on one side and the base plate (8) are not provided integrally but are independent and free, the plate spring is (3A) and the base plate (8) hardly interfere with each other's movement. Similarly, when the pressure is released to restore the linear shape and close, the movement of the other is hardly hindered.

Similarly, a supplementary description of a part of the paper clip (1a), which is the second embodiment, will be given. In FIG. 13, the one leaf spring (3Aa) and the base plate (8a) before being integrally provided with the one leaf spring (3Aa) are pushed outward ( It is an explanatory diagram viewed from above in an open state bent in the direction of arrow G1). The remaining leaf spring (3Ba) is omitted for the sake of explanation. In other words, FIG. 13 is a diagram showing a part of the leaf spring (3Aa) and the base plate (8a) in FIG. There is.
As shown in FIG. 13, in a state in which the one leaf spring (3Aa) and the base plate (8a) are not provided integrally but are independent and free, both ends of the clamping member are pressed to move outward. When the base plate (8a) is bent in an open state (arrow G1), on the side surface (21) excluding the central portion (14a) of the base plate (8a), between one leaf spring (3Aa) and the base plate (8a) , a gap (22) is generated. As described in Example 1, in Example 2 as well, the base plate (8a) bends outward (arrow G1) to open at a constant speed, while one leaf spring ( 3Aa) quickly bends outward (arrow G1) at a certain timing and opens, so when both ends of the clamping member are pressed, one leaf spring (3Aa) bends outward (arrow G1). At the same time, the base plate (8a) is also bent outward (arrow G1) and opened by being pushed by the bending and opening, so that the central portion of the one leaf spring (3Aa) and the base plate (8a) are bent outward (arrow G1). ) contact with the central portion (14a). Although the central portion (14a) is in contact, a gap (22) is generated between the leaf spring (3Aa) on one side and the base plate (8a) on the side surface (21) excluding the central portion (14a). In this way, in the state in which the one leaf spring (3Aa) and the base plate (8a) are not provided integrally but are independent and free, the movement of bending outward (arrow G1) to open For example, the central portion of the leaf spring (3Aa) on one side and the central portion (14a) of the base plate (8a) come into contact with each other, and the movement of the leaf spring (3Aa) on the one side is controlled by the base plate (8a). There is a movement that seems to suppress the part.

As described above, in Example 2, when the one leaf spring (3Aa) and the base plate (8a) are not provided integrally but are made independent and free, they are bent outward (arrow G1). In the opening movement, for example, the movement of the plate spring (3Aa) on one side is partially suppressed by the base plate (8a). In a state in which the spring (3A) and the base plate (8) are not provided integrally but are independent and free, in the movement of bending outward (arrow G1) to open, for example, one of the leaf springs There is little movement that the base plate (8) restrains the movement of (3A).

As described above, in Example 1, in FIGS. A plate (8) is inserted and, for example, one leaf spring (3A) is fixed to the base plate (8). A base plate (8) is arranged inward (arrow U1) side of one leaf spring (3A), and the one leaf spring (3A) and the base plate (8) are fixed. The base plate (8) is inserted between the concave surface (4A) and the concave surface (4B) of the plate springs (3A) and (3B) facing each other, and the plate spring (3A) on one side (arrow U1 ) side of the base plate (8), even if the plate spring (3A) on one side and the base plate (8) are partially fixed, the outward (arrow G1) (arrow G2) Even in the case of bending to open, or restoring to a straight line and closing, there is an effect that each other hardly interferes with the other's movement, and there is little restraining movement (effect 1-6).

As described above, the paper clip (1) of Example 1 is constructed as follows. One leaf spring (3A) and the base plate (8) are fixed. For example, one end (19A) of the one leaf spring (3A) and a hinge (6A) are fixed by an eyelet (12A), and at the same time, the one end (19A) and The base plate (8) is fixed with an eyelet (12A), and further, one leaf spring (3A) and the base plate (8) are fixed with a caulking (13A). In other words, even in the case of bending outward (arrow G1) (arrow G2) to open, or restoring linearly to close, each other hardly interferes with the other's movement, and there is little restraint. Thus, the central portion of the one leaf spring (3A) and the central portion (14) of the base plate (8) are provided so as not to adhere to each other. However, although the effect (effect 1-6) is reduced, the center portions of the one leaf spring (3A) and the center portion (14) of the base plate (8) are partially fixed to each other. well, and it works.

Regarding the paper clip (1a) of Example 2, although not shown, the central portion of the one leaf spring (3Aa) and the central portion (14a) of the base plate (8a) They may be fixed together.

Next, the paper clip (1b), which is Example 3, will be described. As described above, the paper clamp (1) of the first embodiment is, for example, one of the two ends (9A) and (9B) of the base plate (8), at one (9A), the other leaf spring There is almost no gap between (3B) and the base plate (8). Therefore, for example, a sheet of paper used for a commercially available memo pad or the like can be sandwiched at the relevant location. That is, in the paper holder (1) of the first embodiment, the tip of the two eyelets or the like is fixed to the hinge (6A) and the one end (19C) of the remaining leaf spring (3B). Or a part of hinge (6A) and paper contact|abut. By abutting, it is clamped and has a constant clamping force.

The paper clip (1b), which is Example 3, is the same as Example 1 in FIG. 10, but is further modified as follows. In addition, some symbols are omitted in FIG. As described above, they are clamped by abutting each other. In order to further improve the clamping force, the following measures are taken. In FIG. 10, a base plate (15A) is provided integrally with one of the leaf springs (3Ab) to hold down the clamped object (11) closed by releasing the pressure. 8b) side.

For example, at one end (18Ab) of both ends (9Ab) and (9Bb) of the base plate (8b), a restraining piece (15A) is provided on the inner (arrow U1) side of the base plate (8b). be. For example, for a holding member (7b) in which one end (19Ab) of both ends of one leaf spring (3Ab) is connected to a hinge (6Ab), the one end (19Ab) and the hinge (6Ab) ) are fixed by eyelets. At the same time, the base plate (8b), the restraining piece (15A), and the one end (19Ab) are fixed together by means of eyelets. That is, from the outside, the hinge (6Ab), one end (19Ab) of the one leaf spring (3Ab), the base plate (8b), and the restraining piece (15A) are arranged in this order and fixed with eyelets, It is provided integrally. As a result, for example, a hinge (6Ab), one end (19Ab) of one leaf spring (3Ab), a base plate (8b), and a restraining piece (15A) are fixed to each other. The tip or the like or a part of the restraining piece (15A) and the paper come into contact with each other. By abutting, there is an effect that it is clamped and a constant clamping force is improved (effect 3-1). Also, although not shown, the same applies to a portion of the holding member (7b) where one end (19Bb) of both ends of one leaf spring (3Ab) is connected to the hinge (6Bb).

Next, the paper clip (1c), which is Example 4, will be described. As described above, the paper clip (1) of the first embodiment is configured, for example, in the vicinity of the central portion (14) of the base plate (8) by the remaining leaf spring (3B) and the base plate (8 ), a gap (23) is generated between them. Therefore, for example, it is difficult to sandwich one sheet of paper used in a commercially available memo pad or the like, but it is possible to sandwich it by stacking several sheets of paper. In this case, in the paper holder (1) of the first embodiment, the remaining leaf spring (3B) and the paper are brought into contact with each other. By abutting, it is clamped and has a constant clamping force.

The paper clip (1c), which is Example 4, is the same as Example 1 in FIG. 11, but is further modified as follows. In addition, some symbols are omitted in FIG. As described above, they are clamped by abutting each other. In order to further improve the clamping force, the following measures are taken. In FIG. 11, a base plate (15C) is provided integrally with one of the leaf springs (3Ac) to hold down the clamped object (11) that is closed and pinched by releasing the pressure. 8c) side.

For example, in the central portion (14c) of the base plate (8c), a restraining piece (15C) is provided inward (arrow U1) (arrow U2) from the base plate (8c). The central portion (14c) of the base plate (8c) and the restraining piece (15C) are arranged in this order from the outside (arrow G1) (arrow G2) side, and are fixed by eyelets (17A) (17B) or the like to be integrated. It is purposely set. That is, for example, the ends of eyelets (17A) and (17B) or the like, or a portion of the restraining piece (15C), are fixed to the central portion (14c) of the base plate (8c) and the restraining piece (15C). and the paper come into contact with each other. By abutting, there is an effect that it is clamped and a constant clamping force is improved (effect 4-1). Further, instead of the eyelets, caulking or rivets may be used.

In Embodiments 3 and 4, the material of the restraining pieces (15A), (15B), and (15C) is a soft synthetic resin similar to that of the base plates (8b) and (8c), but other materials such as metal can also be used. good. In addition, it may be provided freely including the cross-sectional shape. Further, in Embodiment 4, the central portion (14c) of the base plate (8c) and the restraining piece (15C) may be adhered instead of the eyelets (17A) (17B).

In Example 3, for example, at one end (18Ab) of both ends (9Ab) and (9Bb) of the base plate (8b), the inner (arrow U1) (arrow U2) side of the base plate (8b) A restraining piece (15A) is provided, and in the fourth embodiment, for example, the central portion (14c) of the base plate (8c) is pushed inward (arrow U1) (arrow U2) from the base plate (8c). Although the stop piece (15C) is provided, in Example 3, unlike Example 4, it is provided at both ends of the base plate instead of at the center of the base plate, so that both ends of the clamping member can be pressed. There is no resistance due to the bending of the restraining piece (15C) that occurs when opening by bending outward (arrow G1) (arrow G2), and there is an effect that it is easy to open (effect 3-2). .

Further, the third embodiment may be modified as follows, similarly to the first embodiment. In the case of bending outward (arrow G1) (arrow G2) to open, or straightening back to closing, the movement of each other is less hindered and restrained. In addition, the central portion of the one leaf spring (3Ab) and the central portion of the base plate (8b) are provided so as not to adhere to each other. However, although the effect (effect 1-6) is reduced, the center portions of the one leaf spring (3Ab) and the center portion of the base plate (8b) may be partially fixed to each other, effects occur.

Further, the first and third embodiments may be modified as follows. The side surfaces excluding the central portion and the vicinity of the central portion of the one leaf spring (3A) (3Ab) and the central portion and the vicinity of the central portion of the base plate (8) (8b) are partially fixed to each other. good too.

Further, the fourth embodiment may be modified as follows in the same manner as the second embodiment. Regarding the paper clip (1c) of Example 4, although not shown in particular, the central part (16) of the leaf spring (3Ac) on one side and the central part (14c) of the base plate (8c) have a central The parts may be fixed to each other. That is, from the outside (arrow G1) (arrow G2) side, the central portion (16) of the one leaf spring (3Ac), the central portion (14c) of the base plate (8c), and the restraining piece (15C) are arranged in this order. They may be arranged and fixed with eyelets or the like to be provided integrally.

Further, although not shown, the paper clip (1c) of the fourth embodiment may be configured as follows. A restraining piece (15C) for restraining the clamped object (11) which is closed and pinched by releasing the pressure is provided on the side of the base plate (8c) fixed to the one leaf spring (3Ac), and Instead, a restraining portion for restraining the clamped body (11) closed by releasing the pressure is provided on the side of the base plate (8c) fixed to the leaf spring (3Ac) on one side. good too. For example, the restraining portion may partially increase the thickness of the base plate (8c) only at the central portion (14c) of the base plate (8c).
