[0005]
[Problems to be solved by the invention]
By the way, such a conventional clip is opened against the spring force of the clip when the clip is taken in and out. However, since the clip is made only of resin, the holding force is weak, and when the clip is put in and taken out. When the opening / closing operation is frequently repeated, stress concentrates on the deformed portion of the clip and fatigue occurs, which causes a problem that the elastic force is reduced and the holding force is further reduced. Such a decrease in the holding power of the clip can be easily caused by dropping and exercising with the writing instrument inserted in the breast pocket, for example, when it is dropped or damaged, especially when the clothing cloth is thin. It happened remarkably.
[0006]
The present invention has been made in view of the above problems, and does not cause a decrease in holding force even if frequent opening and closing operations are repeated. An object of the present invention is to provide a user-friendly clip that can be used and a tool to which the clip is attached.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the clip of the present invention comprises a pair of synthetic resin clip pieces whose rear end portions are pivotally held so that the front end portions can approach and separate from each other, and an intermediate portion between the two clip pieces. And a synthetic resin operation lever having a cam shaft inserted within the opposing interval of the portion, wherein the cam shaft expands the opposing interval by a one-way rotation operation of the operation lever. When the distal ends of both clip pieces are close to each other, the unlocking claw provided on the cam shaft is fitted in at least one of the escape grooves formed in either of the clip pieces by the other direction of rotation operation of the operation lever. It is characterized in that the tip of the clip piece can be separated.
According to this feature, the mechanical pinching force by the camshaft is given, so that the holding force does not decrease even if the opening / closing operation is repeated, and the unlocking claw can be immediately fitted into the escape groove. Thus, the tip portions of both clip pieces can be easily separated by a small number of rotation operations of the operation lever.
[0008]
Further, in the clip of the present invention, it is preferable that the distal ends of both clip pieces can be approached and separated within a rotation range of about 45 degrees of the operation lever.
With this configuration, since the rotation range of the operation lever is within approximately 45 degrees, not only the rotation operation of the operation lever can be performed easily, but also the movement range of the operation lever is small. Even if there is, there is no danger of contact with other things.
[0009]
In the clip of the present invention, it is preferable that rear ends of the pair of clip pieces are fitted and held with each other.
With this configuration, the clip operation can be performed without using the engagement spring that suppresses the rear end portions of the pair of clip pieces, so that the number of components can be reduced.
[0010]
In the writing implement to which the clip of the present invention is attached, one clip piece of the above-described clip of the present invention is integrally formed with the writing implement main body or a part thereof, and the other clip piece can be moved closer to or away from the writing implement. It is characterized by having.
According to this feature, even in the case of a rod-like material such as a writing utensil, the holding force of the clip can be easily and strongly increased by cooperating with the other clip piece, if necessary, by rotating the operation lever with a small amount. As a result, it can be securely held between thin cloths such as pockets. In addition, since the holding force can be easily reduced by the reverse operation of the lever, the lever can be easily pulled out from the pocket.
[0011]
In the writing instrument to which the clip of the present invention is attached, one clip piece of the above-described clip of the present invention is attached to the writing instrument body or a part thereof, and the other clip piece can be moved closer to or away from the writing instrument. It is characterized by:
According to this feature, the writing implement main body or a part thereof and one of the clip pieces are separately attached to each other, so that the writing implement main body or a part thereof can be manufactured with different materials and colors.
[0012]
The clip board to which the clip of the present invention is attached is characterized in that one clip piece of the clip of the present invention is attached to a flat board, and the other clip piece can be moved closer to or away from the board.
According to this feature, even a large number of documents can be reliably held by the cooperation of the flat board and the other clip piece.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a perspective view showing a state in which a clip according to a first embodiment of the present invention is provided on a cap of a writing implement. FIG. 2 is a clip provided on a cap of a writing implement. FIG. 4B is a cross-sectional view illustrating a state in which the distal ends of the clip pieces are separated from each other, and FIG. 4B is a cross-sectional view illustrating a state in which the distal ends of the clip pieces approach each other by operating the operation lever. Writing instruments that are one of the objects of the present invention are ballpoint pens, mechanical pencils, felt-tip pens, and the like, and the shaft structure is a cap-type, knock-type, double-type writing instrument, and the like.
[0015]
Reference numeral 1 shown in FIGS. 1 and 2 is a clip. This clip 1 is a pair of synthetic resin clip pieces 4 whose rear end portions are pivotally held so that the front end portions can approach and separate from each other. 5 and a synthetic resin operating lever 8 having a camshaft CM inserted into the opposed space between the upper and lower holding frames disposed at the intermediate portion between the clip pieces 4 and 5.
[0016]
Specifically, one clip piece 4 is formed with a narrow through-hole 4a at a step formed at the rear thereof, and is formed at the lower end of the step to be slightly narrower than the through-hole 4a. The lower holding frame 10 is extended rearward.
[0017]
The other clip piece 5 includes a cap 2 opposed to the clip piece 4 in the case of a writing instrument, and an upper holding frame 6 disposed opposite to an upper portion of a lower holding frame 10 fitted and held at a rear end thereof. It is composed of As described above, if the cap 2 and the upper holding frame 6 have different configurations, it is possible to manufacture the cap 2 and the upper holding frame 6 with different materials and colors, but the cap 2 and the upper holding frame 6 are integrated. It may be something.
[0018]
Although the clip piece 5 is described as being configured as a cap of a writing implement, it is not particularly limited to the cap, and will be described in detail later. No.
[0019]
The upper holding frame 6 is bent downward in a U-shape, and the locking claw 6 a facing the inside of the lower rear end is fitted and held in the locking groove at the rear end of the cap 2. The upper locking claw 12 spaced forward from the rear end of the cap 2 is locked by a locking hole 6c at the front lower portion through which the 4a is inserted downward, and is integrated with the cap 2.
[0020]
A rectangular locking hole 6b is formed behind the upper holding frame 6, and a locking projection 4b formed at the rear end of the lower holding frame 10 is locked in the locking hole 6b. .
[0021]
Reference numeral 8 denotes an operation lever. The operation lever 8 has a cam shaft CM formed between both side plates at the front end formed to have the same width as one of the clip pieces 4 and has both sides behind the cam shaft CM. The rear portion of the upper holding frame 6 is inserted into the through-hole 8a formed between the plates, and the cam shaft CM is held between the lower holding frame 10 and the upper holding frame 6 disposed opposite to the upper portion. Is done.
[0022]
The cam shaft CM is formed in the center thereof in a cross-shaped cross section by narrow lock release claws 14a, 14b and lock claws 15a, 15b shorter than the lock release claws 14a, 14b. When the unlocking claws 14a, 14b are rotated 45 degrees counterclockwise (in the unlocking direction) with respect to the horizontal axis on the opposing inner surfaces of the holding frame 10, the tips of the unlocking claws 14a, 14b are fitted into contact with each other to limit the rotation range. A pair of clearance grooves 16 and 18 for regulating are formed.
[0023]
Therefore, as shown in FIG. 2A, when the operating lever 8 is rotated to a position substantially parallel to the axis of the cap 2, the tips of the unlocking claws 14a and 14b of the camshaft CM are turned into a pair of reliefs. It is positioned in the 45-degree direction by contacting the grooves 16 and 18.
[0024]
In this state, the distal ends of the other lock claws 15a and 15b rotated in the 45-degree direction release the pressing force against the opposing inner surfaces of the upper holding frame 6 and the lower holding frame 10, and the pair of escapes Since the grooves 16 and 18 are formed deeper than the lock release claws 14a and 14b, the one clip piece 4 and the other clip piece 5 can move in the opening direction by the deeply formed relief groove depth.
[0025]
Further, as shown in FIG. 2B, by rotating the operation lever 8 downward by about 45 degrees, the tips of the unlocking claws 14a, 14b are separated from the pair of escape grooves 16, 18 and simultaneously, The tips of the lock claws 15a and 15b positioned in the directions press the opposing inner surfaces of the upper holding frame 6 and the lower holding frame 10.
[0026]
The lower holding frame 10 pressed by this rotates downward with the locking projection 4b fitted and held in the locking hole 6b behind the upper holding frame 6 as a fulcrum, and the clip piece 4 moves downward. Is enlarged, and the side surface of the cap 2 which is the other clip piece 5 is pressed.
[0027]
Therefore, since the mechanical clamping force is applied by the camshaft CM, the holding force does not decrease even if the opening / closing operation is repeated, and the unlocking claws 14a, 14b are immediately fitted into the pair of clearance grooves 16, 18. By doing so, the distal ends of the clip pieces 4 and 5 can be easily separated with a small number of rotation operations of the operation lever 8.
[0028]
In addition, since the rotation range of the operation lever 8 is within approximately 45 degrees, not only can the rotation operation of the operation lever 8 be performed easily, but also because the movement range of the operation lever 8 is small, the operation lever 8 can be tilted. Even if there is, there is no danger of contact with other things.
[0029]
Further, since the rear ends of the pair of clip pieces 4, 5 are fitted and held with each other, the clip action can be achieved without using an engagement spring for suppressing the rear ends of both clip pieces 4, 5. Therefore, the number of parts can be reduced.
[0030]
The other clip piece 5 is configured as a part of the cap 2 as a writing instrument, and the one clip piece 4 is configured so as to be able to approach and separate from the side surface of the cap 2. Even in the case of such a rod-shaped member, it can be reliably held between thin cloths such as pockets by the cooperative action with one clip piece 4.
[0031]
In the above-described embodiment, the other clip piece 5 is configured as a part of the cap 2 of the writing implement. However, it is needless to say that the clip piece 5 can be applied to the main body shaft as shown in FIG. FIG. 3 is a perspective view of an integrated writing implement in which the clip of the present invention is provided on the top of the writing implement. The clip 1 of the present invention is provided on the top of the writing implement main body 2 '.
