Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for holding clothes, documents, etc. therebetween.

[0002]

2. Description of the Related Art Conventionally, as a clip, for example, a clothespin has a substantially V-shape with two holding pieces, and the spring force of a spring always closes a holding opening at one end. Are known.

In a clip having such a structure, in use, a force is applied to an input portion on the opposite side of the holding opening to insert the object to be held with the holding opening in an open state and then applied to the input portion. By removing the applied force, the clamping port is closed and the object to be clamped is clamped by the spring force.

[0004]

In the above-mentioned conventional clip, when an object is pinched in the holding opening, a) operation for applying a force to the input section, and b) removing the force applied to the input section. 2) operation had to be performed continuously.

[0005] However, such a continuous operation is complicated, and it has been desired to improve usability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and it has been made extremely easy to improve the usability by eliminating the need to continuously perform two operations when clipping an object with a clip. It is intended to be achieved by a simple configuration.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 connects an intermediate portion in which two holding pieces are separated from each other so as to be relatively rotatable, and a spring force of a spring member. By using a leaf spring as the spring member, in a clip configured to close a holding opening formed by one end of both holding pieces and to hold an object to be held in the holding opening, The leaf spring has a length such that the displacement of the intermediate portion when the intermediate portion is flexed is larger than the distance between the intermediate portions of the holding pieces, and both ends of the leaf spring rotate the holding piece. Is mounted between the two holding pieces while being attached to the inside of one of the holding pieces while straddling the center of the holding piece and the intermediate portion is pressed against the inside of the other holding piece with a predetermined or more spring force. And

[0008] In this clip, the leaf spring is pressed against the inside of the other holding piece with a predetermined or more spring force. At this time,
The interval between the two holding pieces is such that one expands across the center of rotation and the other narrows, and accordingly, the most bulging position of the leaf spring is biased toward the side where the interval is widening. Thus, the spring force of the leaf spring acts in such a direction as to further widen the side where the interval between the two holding pieces is widened, and maintains that state. Then, from this state, when the both holding pieces are relatively rotated so that the interval on the opposite side becomes wider, contrary to that, the most bulging of the middle portion of the leaf spring according to the change of this interval. The position moves to the opposite side across the center of rotation. Therefore, the spring force of this leaf spring is
On the contrary, it works in the direction of further expanding the newly widened side, and maintains that state. Therefore, the clip of the present invention can be maintained in any of the opened state and the closed state of the holding opening at one end. When such a clip of the present invention is used, when the clip opening is maintained open as in a general clip and an input is made to open the clip opening, the interval between both clipping pieces is increased. In a state in which the gap on the side of the holding opening is narrower than the opposite side with respect to the center of movement, the spring force of the leaf spring acts in a direction to close the holding opening, so if input is removed from this state, The clip opening can be closed to hold an object. In this case, the clip can be used in the same manner as a conventional clip.

On the other hand, when the force is applied without removing the input, and the interval on the side of the holding opening is wider than the interval on the opposite side, the spring force of the leaf spring acts to open the holding opening. That is, the clip is maintained in a state where the clip opening is opened. Therefore, the next time an object is pinched, only one operation of inputting an input in the direction to close the pinch opening portion needs to be performed.

In addition, as described in claim 2, claim 1
In the clip described above, the attachment position of the both ends of the leaf spring to the holding piece is the distance from the attachment position of the end on the side of the holding opening to the center position of the rotation, opposite to the holding opening. It is preferable to set the distance shorter than the distance from the attachment position of the end portion to the center position of rotation. Thereby, the most swelled position of the intermediate portion of the leaf spring is easily arranged on the opposite side to the holding opening with respect to the center position of rotation, that is, the direction in which the spring force of the leaf spring closes the holding opening. And the closed state is easily maintained.

[0011] Further, as described in claim 3, claim 1
In the clip described in (2), it is preferable that both ends of the leaf spring are attached to the holding pieces by locking the holding pieces in locking grooves formed in the width direction of the holding pieces. Therefore, the work of attaching the leaf spring is easier than the case where the work involves fixing work such as screwing.

Further, as described in claim 4, claim 3
In the above-described clip, it is preferable that three or more of the locking grooves are formed so that the attachment position of at least one end of the leaf spring can be changed. Therefore, by arbitrarily selecting the attachment positions at both ends of the leaf spring, the relationship between the swelling position of the intermediate portion of the leaf spring toward one of the holding pieces and the center position of rotation is arbitrarily selected. It is possible to arbitrarily adjust the direction in which the spring force of the leaf spring acts to rotate the holding piece and the degree of the force, and the work locks the end of the leaf spring and the locking groove. It can be done with only simple tasks.

[0013] Also, as described in claim 5, claim 1 is
In the clip according to any one of (4) to (4), an engagement groove which engages with a side edge of the leaf spring and regulates movement of the leaf spring in the width direction is formed inside the holding piece to which the leaf spring is pressed. Is preferred. In the clip of the present invention, the contact position of the intermediate portion of the leaf spring with respect to the holding piece moves when operated, but at this time, the operation is stable without the leaf spring moving in the width direction.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of the clip of the embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a bottom view thereof, FIG. 4 is a side view thereof, and FIG.
FIG. 5 is a sectional view taken along line S5-S5 of FIG. 4, and the clip CL according to the embodiment includes two holding pieces 1 and 2 and one leaf spring 3;
It has. Each of the holding pieces 1 and 2 is formed of a resin. A connecting projection 2a is provided at the center of one holding piece 2 and the connecting projection 2a is provided at the center of the other holding piece 1.
a are extended from both left and right sides, and pins 4 are inserted into connection holes provided in these 2a, 1a, 1a, and the two holding pieces 1, 2 are relatively rotated. It is movably connected.

Further, a clip opening portion 11 is provided at one end of the clip CL so that the holding surfaces 1b, 2b formed at one end of the both holding pieces 1, 2 face each other and come into contact with each other.
The other ends of the holding pieces 1 and 2 are gripping portions 1d and 2d, which are input points of the operating force. A lateral groove is formed in each of the holding surfaces 1b and 2b in the width direction. A hole 2e is formed through the grip 2d.

On the inner surface of the holding piece 2, a plurality of locking grooves 2f, 2 are formed on both sides of the connecting projection 2a.
g is formed in the width direction, and the leaf spring 3 is engaged with the retaining grooves 2f, 2g at both ends so as to straddle the pin 4, which is the center of rotation, between the sandwiching pieces 1, 2. Have been. Further, in the present embodiment, when the plate spring 3 is bent at both ends by being locked in the locking grooves 2f and 2g and the center portion is bent upward in FIG. It is set to a length just enough to press against. In the example shown in FIG. 1, the distance from the locking position of the leaf spring 3 to the locking groove 2g to the pin 4 is greater than the distance from the locking position to the locking groove 2f to the pin 4. As a result, the position of the bulge point 3a of the leaf spring 3 that bulges upward is more likely to be located on the left side in the figure than the pin 4.

As shown in FIGS. 4 and 5, an inner surface of the holding piece 1 is engaged with the leaf spring 3 in the width direction to prevent the position of the leaf spring 3 from shifting in the width direction. A mating groove 1c is formed.

Next, how to use the clip CL will be described.

A) Normal usage method First, a usage method similar to that of a conventional clip will be described.

As is well known, when a force is applied so as to sandwich the grips 1d and 2d from the state in which the holding opening 11 shown in FIG. 1 is closed, the clip CL deforms the leaf spring 3 while
Open the holding opening 11. At this time, as shown in FIG. 1, when the interval between the holding pieces 1 and 2 is wider on the left side in the figure than the pin 4 as shown, the spring force of the leaf spring 3 is increased at the position of the bulging point 3a. It works so as to widen the interval between the holding pieces 1 and 2. Therefore, when the force applied to both grip portions 1d and 2d is weakened or removed, the two holding pieces 1 and 2 of the clip CL operate in the direction to close the holding opening 11 as shown in the drawing. After the holding opening 11 is opened once, the inserted one can be held between them.

(B) A method of using the gripping opening 11 to maintain the open state The force is continuously applied to both gripping portions 1d and 2d, and the interval between the gripping pieces 1 and 2 is on the right side of the pin 4 in FIG. When it spreads further, the position of the bulging point 3a of the leaf spring 3 moves to the right side of the pin 4 in FIG. In this state, the spring force of the leaf spring 3 acts in a direction to separate the two holding portions 1b and 2b. Therefore, the clip CL
Is maintained in a state where the holding opening 11 is opened.

Thereafter, when an object is to be inserted into the opening 11,
After an object is sandwiched between the holding openings 11, a force is applied from the outside so as to sandwich the holding portions 1b and 2b to relatively rotate the two holding pieces 1 and 2, whereby the expansion of the leaf spring 3 is caused. When the position of the outgoing point 3a moves to the left of the pin 4 in FIG. 1 in FIG. 1, the spring force of the leaf spring 3 acts so as to widen the gap between the grip portions 1d and 2d, and the opening portion 11 closes. Can be maintained.

As described above, when an object is to be clamped after the holding opening 11 is maintained in the open state, only one operation of applying a force to the holding opening 11 from the outside is required. Therefore, a plurality of objects to be clamped are respectively connected to a plurality of clips C.
In the case of sandwiching with L, a plurality of clips CL are respectively maintained in the above-described open state in advance, and thereafter, after each object to be held is sandwiched between each of the opening portions 11, each of the clip openings is provided for each of the clips CL. One operation of applying a force to close the portion 11 can be performed continuously, and the holding can be performed in a short time.

As described above, the clip CL of the present embodiment can be maintained in any one of the two states: the holding state in which the holding opening 11 is closed, and the opening state in which the holding opening 11 is open. The gripping part 1 can be
a method of sandwiching an object by two operations of an operation of applying a force to d and 2d and an operation of weakening the force;
At the time of holding, the method of holding the object to be held by only one operation can be properly used, and the usability can be improved.

In order to improve the usability, it is not necessary to add a configuration such as a stopper for maintaining an open state as compared with the conventional structure.
It is composed of three members, one holding piece 1 and 2 and one spring (leaf spring 3), and the effect of improving the usability with a simple configuration can be obtained.

Further, in the clip CL according to the present embodiment, since a plurality of locking grooves 2f and 2g are formed, by changing the locking position of the leaf spring 3, the clip CL acts to close the holding opening 11. The spring force to be applied can be appropriately changed, and the effect that the usability can be further improved can be obtained. For example, when the locking position of the leaf spring 3 is moved away from the pin 4 from the state shown in FIG.
The force for closing the holding opening 11 is weakened, and the force for closing the holding opening 11 increases when the position where the leaf spring 3 is locked to the locking groove 2f is brought closer to the pin 4 in the drawing.

In addition, since the both side edges of the intermediate portion of the leaf spring 3 are engaged with the engaging grooves 1c in the width direction, the position of the bulging position 3a of the leaf spring 3 moves the pin 4 as described above. When the leaf spring 3 is moved in the left-right direction in FIG.
2 does not move in the width direction, and the operation is stable.

[0029]

As described above, in the clip according to the present invention as set forth in claims 1 to 5, a leaf spring is provided between the two holding pieces, and this leaf spring is bent when its intermediate portion is bent. The displacement of the intermediate portion is long enough to be larger than the distance between the intermediate portions of the holding pieces, and both ends of the holding portion are placed inside one holding piece across the center of rotation of the holding piece. It is configured to be attached between the two holding pieces in a state where it is worn and the intermediate portion is pressed against the inside of the other holding piece with a predetermined or more spring force, so that the holding opening at one end is opened. An effect is obtained that a novel clip that can be maintained in any of the closed states can be provided by a simple configuration including two holding pieces and one leaf spring, which is the same as the conventional clip. In the clip of the present invention,
When holding the object after keeping the holding mouth part open,
It is sufficient to perform only one operation of inputting the input in the direction to close the holding opening, and the effect that the usability can be improved can be obtained.

According to the second aspect of the present invention, the position at which both ends of the leaf spring are attached to the holding piece is determined by the distance from the attachment position of the end on the holding opening side to the center of rotation. Since the distance from the attachment position of the end opposite to the holding opening to the center of rotation is set shorter, the spring force of the leaf spring easily acts in the direction to close the holding opening, and this closed state is set. It is easy to maintain, and the effect of improving usability can be obtained.

According to the third aspect of the present invention, both ends of the leaf spring are attached to the holding pieces by locking the holding pieces in locking grooves formed in the width direction of the holding pieces. The work of attaching the leaf spring is easier than in the case where the work involves fixing work such as screwing, and the effect of improving productivity and reducing costs can be obtained.

Further, in the invention according to claim 4, three or more locking grooves are formed and the attachment position of at least one end of the leaf spring can be changed, so that the attachment positions of both ends of the leaf spring can be changed. By arbitrarily selecting, it is possible to obtain the effect that the direction in which the spring force of the leaf spring acts to rotate the holding piece and the degree of the force can be arbitrarily adjusted. This can be effected by a simple operation of only locking the end of the groove and the locking groove.

According to the fifth aspect of the present invention, the inside of the holding piece to which the leaf spring is pressed is engaged with the side edge of the leaf spring to restrict the movement of the leaf spring in the width direction. Since the groove is formed, when the contact position of the intermediate portion of the leaf spring to the holding piece moves, the leaf spring does not move in the width direction, the operation is stable, and the effect that the product quality can be improved can be achieved. can get.
