Description

  The present invention relates to a pinch unit that can be removably attached to a support member, and more particularly to a pinch unit that pinches the laundry to dry the laundry, and a clothesliner equipped with a plurality of the pinch units.

  Pinch is mainly attached to clothes hangers as clothespins, and is widely used for clothesliners and the like.

  In a hanger using such a pinch unit, when many clothes are to be dried at the same time, it is necessary to release the clothes by holding the tip of each pinch one by one when taking in the clothes. In the case where a large number of are provided, it is very time-consuming. Also, although it is possible to take in the laundry by pulling it forcibly, it is not preferable because there is a possibility that the pinch may be broken or the laundry may be damaged.

In view of such a thing, in order to improve the effort at the time of laundry intake, in JP-A-8-206395 and JP-A-2001-190896, the power point of both of the pair of pinching pieces is taken into consideration. A configuration is disclosed in which the holding force is high when the laundry is being dried, but the holding force is low when the laundry is removed by sharing the load of the laundry.
However, even in such a configuration, in the case where a heavy item is suspended as described in the specification of Japanese Patent Application Laid-Open No. 2001-190896 (the description of FIGS. 7 and 8), the pinch is There is a risk of releasing it.

  When the hanging direction of the laundry and the pulling direction through the laundry are substantially the same direction as in the configuration of the prior art, the release force of the clamping force accompanying the pulling operation through the laundry There is a limit to the adjustment of the tension, so it is only possible to increase the spring force in the washing pinch, in which case there is a trade-off between the pulling force through the laundry and the pinching force of the pinch member And the previous problem will not be solved.

  In view of this, in the patent 4911490, the present applicant pays attention to the difference between the hanging direction at the time of washing and the pulling direction, and this difference makes it possible to solve the above-mentioned trade-off first. is suggesting.

  Here, even if the pulling direction through the laundry is changed to a different direction in the configuration of the prior art, the pinch itself rotates according to the pulling direction, so the direction of the force acting on the pinch is substantially The previous trade-off can not be resolved because it does not change.

  On the other hand, in the technology of Japanese Patent No. 4911490, the force acting on each of the pinch members (the direction of the force from the support member) is made different by suspending each pinch member with a separate suspension member. ing. Therefore, when the pulling direction through the laundry is changed to a different direction, the rotation of the pinch member on one side can be restricted, and the direction of the force acting on the pinch can be shifted.

  Furthermore, the suspension member is converted to force in the pinch releasing direction by restricting the pivoting operation of the other pinch member to be shallower than the pivoting operation of the pinch member on the rotation direction side. There is.

In addition, since it is necessary to make the above-mentioned suspension member bend so that a pinch member may be pulled to a horizontal direction, it was premised using the flexible material (resin or fiber aggregate) in consideration of the mobility. However, the use of a flexible material for the suspension member has been a hindrance with regard to the two functions of "durability" and "mounting workability".
This will be explained in order.

  First, although it is "durability", in the flexible material in this configuration as described above, when the bending portion is concentrated to a part, that portion is fatigue-deteriorated.

Moreover, in the part which is in contact with the hanger and the pinch member, it repeatedly slides and is worn locally while being loaded by the weight and tension of the laundry.
Furthermore, as a flexible member generally used, resin is not very excellent in weather resistance such as ultraviolet light in outdoor use.

  Therefore, the durability was not sufficient in long-term use where the heavy laundry is frequently dried and taken in.

  Next, although it is "attachment workability", in the above-mentioned composition, fixation (attachment) to a hanger will be performed with a portion of a flexible member, but a flexible member is deformed at the time of attachment It is easy to do so, and it becomes difficult to determine the fixing direction. Moreover, in this configuration, one side of the pinch member must be attached and the other side must be attached. Therefore, the installation operation is performed in a state in which the movement of the pinch member is restricted, and the difficulty of the operation is extremely high. Become.

  Hereinafter, the present invention will be described in detail by the embodiments shown in the drawings.

  In the first embodiment for carrying out the present invention shown in FIGS. 1 to 5, 1 is a pinch unit, and this pinch unit 1 is used to hold the object 2 as a first holding member 3a and a second holding member 3b. The pinch unit 1 is provided with a pinch member 3 for holding the object to be held W by holding the object W, and the pinch unit 1 is detachably engaged with the support member 4 for supporting the pinch member 3; A hard relay holding member 7 having an engaging portion 5 rotatably engaged with the support member 4 and rotatably holding the first holding member 3a by a rotational connection portion 6. And the flexible regulation member 8 which connects the relay holding member 7 and the second holding member 3b and restricts the rotational movement of the second holding member 3b about the rotational connection portion 6 as a fulcrum , And the pinch member 3 is The flexible restricting member 8 restricts the pivoting movement of the second holding member 3b by causing the first holding member side 3a to pivot with the dynamic connection portion 6 as a fulcrum, and the object 2 to be held Is released.

  The support member 4 is formed with a looped engaged portion 9 for engaging the engaging portion 5 of the relay holding member 7. On the other hand, the engaging portion 5 is formed in a hook shape in which a part is opened or in a snap hook shape, so that the engaging portion 9 can be attached to and detached from and rotated by the engaged portion 9. It is engaged in the engaged state. This engagement state ensures the ease of attaching the pinch unit.

In the present embodiment, when the pinch unit performs a pivoting operation with the engaging portion 5 as a fulcrum, the pinch unit contacts the support member and the pivoting is restricted. At this time, the pinch member is held in a cantilever shape by the contact portion of the support member, that is, the rotation restricting portion acting only on the relay holding member. As a result, when a force in the further rotation direction acts on the pinch member, a rotation movement toward the first holding member 3a with the rotation connection portion as a fulcrum is performed. There is.
The pinch member 3 includes a holding portion 11 for holding the object 2; a hinge portion 12 serving as a fulcrum of the pinch member 3; a spring member 13 for giving a holding force to the pinch member 3; It is configured. The tip end of the first holding member 3 a is connected to the relay holding member 7 via the pivot connection portion 6.

  In this embodiment, the relay holding member 7 is rotatably inserted into a through hole formed in the vicinity of the upper end portion of the first holding member 3a of the pinch member 3 in the present embodiment. However, a hinge mechanism or the like may be formed on the upper end portion of the first holding member 3 a of the pinch member 3, and the relay holding member 7 may be connected.

  In the present embodiment, the relay holding member 7 is formed in a strip shape of a hard and rigid material, and an engagement portion 5 engaged with the engaged portion 9 of the support member 4 is formed at one end portion. The other end is connected to the first holding member 3 a via the pivot connection 6.

  The hardness and rigidity of the relay holding material 7 may be as high as that of polypropylene resin, and materials such as synthetic resin, ceramic, metal, etc. may be used.

  Further, the shape of the relay holding member 7 is not limited to a belt shape, and may be a round rod shape, a rectangular cross section, or any shape. However, the relay holding member 7 may have any shape. With regard to the shape and the shape of the connecting hole of the pinch member 3, the turning direction of the turning connecting portion 6 turns in the direction intersecting the extending direction of the flexible restricting member 8 (in FIG. 1, the far side direction). It is formed to regulate. For example, the cross-sectional shape of the relay holding material 7 of the present embodiment and the shape of the pinch member 3 connection hole are rectangular.

  One end of the flexible restricting member 8 is attached near the rotation connection 6 of the relay holding member 7 (for example, a position within 1/2 of the pinch member length from the rotation connection 6), and the other end Is attached to the second holding member 3 b of the pinch member 3. The optimum mounting position of one end of the flexible regulating member 8 will be described later.

  Here, an invention (conventional pinch) described in Patent Document 3 (Japanese Patent Application Laid-Open No. 8-206395) will be described as an example of the force required to release the conventional pinch.

  Japanese Patent Application Laid-Open No. 8-206395 describes the load necessary for removing the laundry from the pinch for each of various configurations, including the conventional example (FIG. 6) of the prior art. According to this description, in the invention described in FIG. 1, the load required to release the laundry from the pinch is 800 g and is described in (a), (b) and (c) in FIG. The inventions described above are 875 g, 775 g, and 1075 g, respectively, and the invention described in FIG. 6 is considered to be 2850 g. The difference in load required for this separation is mainly caused by the difference in the direction of the tensile force applied to the rear end of the pinch member, since the tensile direction is basically the same.

  As can be seen from the difference in the separation load for each of these configurations, the point of the force necessary for releasing the clamping force is in the direction crossing the pulling direction through the laundry at the pinch member rear end (pinch member rear end The separation load decreases as the magnitude of the force in the direction connecting the rear end portions in (4) increases.

  The pulling force F through the laundry 2 is decomposed as the pulling force f applied to the hanging members at both ends of the pinch member, and is further converted to a force vector f2 of the pulling direction and a vector f1 of the force crossing the pulling direction. In consideration of disassembly, if the direction of the reaction force of the force supported by the hanger is made as close as possible to the direction connecting the rear end portions of the pinch member rear end portions, the force vector f1 in that direction becomes large (See FIG. 3 (a) of the present application).

  Taking this into consideration, in the configuration of the present invention, the portions to which the pulling force is applied via the object 2 are respectively in the vicinity of the rear end of the pinch member 3 to turn the pinch member 3 in the lateral direction. Since the force can be used almost as it is for releasing the holding force, the object to be held 2 which is the object to be held can be released with a further smaller force than the configuration of the aforementioned Patent Document 2.

That is, when the workpiece 2 is pulled in the lateral direction by the force F, since the relay holding member 7 is limited in rotation by the rotation restricting portion 10, the pinch member 3 is pulled with the rotation connecting portion 6 as a fulcrum Try to turn in the other direction. However, since the rotation of the second holding member 3 b of the pinch member 3 is restricted by the flexible restriction member 8, the tensile force F is applied in the connection direction of the flexible restriction member 8. Disassembling this tensile force F means that the second holding member 3b is decomposed into a force f1 for opening the holding portion 11 against the spring force of the spring member 13 and f2 in the direction orthogonal to the f1. it can. At this time, since f1 and F are vectors in substantially the same direction, the force in which the pinch member 3 is turned in the lateral direction can be used almost as it is to release the holding force (see FIG. 3B of the present application). .
On the other hand, in the conventional configuration, the longer the suspension member is, the smaller the magnitude of the force in the direction connecting the rear end portions of the rear end portions of the pinch members 3 becomes. In the configuration of the present invention, the length of the relay holding member 7 does not affect the magnitude of the force connecting the rear end portions of the rear end portions of the pinch members 3.

  Further, in the present configuration, the control of the rotation direction of the pinch member 3 on the rotation side is achieved by contact with the rotation restricting portion 10 integrally formed on the frame as the support member 4. At this time, the restriction state of the relay holding member 7 to the support member 4 acts on only the relay holding member 7 so that the pinch member 3 acts like a cantilever, so that the rear end portion of the pinch member 3 is While being able to perform rotational movement to the said 1st clamping member side which used the rotational connection part 6 provided as a fulcrum, it becomes a structure complete | finished with the mechanism by pinch unit 1 independent.

  Next, the optimum attachment position of one end of the flexible regulating member 8 (a position where the force pivoted in the lateral direction of the pinch can be used almost as it is for releasing the pinching force) is based on FIG. 4 and FIG. Will be described below.

First, the definition of symbols is as follows.
(1) r (ra, rb, rc) is the length to the end of the pinching portion of the pinch member 3 when the flexible regulating member 8 is at the attachment position P (Pa, Pb, Pc) When 3 is opened, the knob end Pm (Pm1, Pm2) of the pinch member 3 pivots on the circumference with r as the radius.
(2) d1 and d2 are differences between the locus of ra and the locus of rb and rc, which are generated when the knob end Pm1 of the pinch member 3 is rotated to Pm2. The distance d by which the end of the pinching portion of the pinching member 3 moves inward to open the pinching member 3 is generated by the difference d1, d2 of the locus on the circumference.
(3) Fm1 and Fm2 are forces for pulling the tip of the pinch member 3 in order to turn it around Pa as the fulcrum because the pinch member 3 is open. dm1 and dm2 are the moving distances. W2 is the amount of work to rotate the tip of the pinch member 3 at this time. The amount of work W2 = Fm1 · dm1 or Fm2 · dm2.
(4) W1 is the amount of work for opening the pinch member 3 by the distance S. F is the force required at that time, and D is the movement distance. The amount of work is W1 = F · D.

Next, the difference in the movement distance dm required for opening the pinch member 3 due to the difference in the attachment position P (Pa, Pb, Pc) of the flexible regulation member 8 will be described.
(1) When the pinch member 3 is rotated to open the pinch member 3, the attachment position Pa can not be attached to this position because the difference of the locus due to the rotation does not occur. Only when the arbitrary positions Pb and Pc below Pa are set as the attachment positions, the differences d1 and d2 are generated, and the opening force of the pinch member 3 is obtained.
(2) The difference is d1 <d2 due to the difference between the attachment positions Pb and Pc, and the difference becomes larger as the distance from Pa is increased. On the contrary, the difference is smaller.

Next, the difference in the force Fm (Fm1, Fm2) required for opening the pinch member 3 due to the difference in the attachment position P (Pa, Pb, Pc) of the flexible regulating member 8 will be described.
(1) The work amount for opening the pinch member 3 by an arbitrary distance S is W1 and equal to W2. This amount of work required to open at any interval S is always constant.
(2) Since the necessary amount of movement for obtaining the amount of work W1 for opening the pinch member 3 by an arbitrary distance S is D and is constant, the same amount of differences d1 and d2 for obtaining D is also necessary. Therefore, the necessary pinch member 3 rotation angle is the attachment position Pb> Pc, and the movement distance is dm1> dm2.
(3) The movement distance is dm1> dm2, and even if dm is different, since the required work amount W2 is constant, the opening force of the pinch member 3 is Fm1 <Fm2.

That is, as the mounting position is closer to Pa, the necessary force Fm may be weaker, the pulling distance dm may be longer, and the necessary pivoting angle for obtaining the dm may be larger. That is, the difference of the required force Fm by the attachment position of the flexibility control member 8 becomes the order of Pa <Pc <Pb.
That is, the mounting position Px that operates (opens) with the least possible force Fm is the most Pa that can ensure the minimum difference d that can obtain S (for example, 5 mm, the maximum expected thickness of the laundry) necessary for design specifications. It will be close. The required force Fm increases with distance from this position, and the effect of opening easily decreases.

  Pb is set so that the force Fm1 required to open the pinch opening at a maximum of 5 mm (corresponding to S) is almost minimized, and the difference in release force depending on the mounting position (Pb, Pc) of the flexible regulating member 8 is measured Compared.

As a result, as shown in FIG. 6, it was demonstrated that the attachment position Pb can be opened with a force about 40% less than Pc. Therefore, even in Patent Document 2 above, it could be released by a weak force, but it could be released by a further 40% weak force, and the pinch unit 1 of the present invention is more excellent.
In addition, the attachment position Pb is a state where the other end of the flexible regulating member 8 is attached to the first sandwiching member 3a after passing through the through hole of the second sandwiching member 3b (hereinafter referred to as the through hole). Even if it does not, it can be released by a force weaker than the through hole of Pc, and in the pinch unit 1 of the present invention, it is not necessary to make the through hole, and the flexible regulating member 8 can be simplified. In addition, in the case of through-hole through productization, the flexible regulating member 8 may move through the through-hole and may be damaged while being used for a certain period of time, but this has the effect of eliminating this.

  In addition, it has been demonstrated that the thinner laundry can be released by a weaker force. The thinner the object to be clamped, the smaller the opening of the pinch, and the smaller the opening force Fm is. This is an excellent feature that can not be realized by the prior art.

  As described above, in the present invention, since one end of the flexible regulating member 8 is attached to the frame (supporting member 4) and the other end can be released by a weaker force than in the through hole passing state, the present invention In this case, there is no need to make the other end of the flexible restricting member 8 through the through hole, and the mounting mode of the flexible restricting member 8 can be simplified.

  Also, if the other end of the flexible regulating member 8 is through the through hole, the flexible regulating member 8 may move through the through hole and may be damaged while being used for a certain period of time, There is an effect that this disappears.

[Different forms for carrying out the invention]
Next, different embodiments for carrying out the present invention shown in FIGS. 7 to 13 will be described. In the description of these different embodiments for carrying out the present invention, the same components as those of the first embodiment for carrying out the present invention will be assigned the same reference numerals and overlapping explanations will be omitted.
The second embodiment of the present invention shown in FIGS. 7 to 9 differs from the first embodiment of the present invention mainly in that the frame of the clothes dryer 14 is used as a support member 4A. In addition, even in the pinch unit 1A configured in this way, the relay holding member 7A in which the projecting rotation restricting member 15 is formed in contact with the supporting member 4A is formed. The same effect as that of the embodiment 1 can be obtained.

  In addition, when the frame of the clothes-dryer is used as a support member, the hanging direction of the laundry as shown in Patent Documents 1 and 2 is substantially the same as the pulling direction through the laundry. Because, in the case of hanging a heavy load that has to be suspended using a large number of pinch members for one laundry, the number of pinch members required to suspend the heavy load can be reduced. , Will be able to dry more laundry than before.

  In addition, when you hang a lot of laundry with plenty of clothesline, if you pull these many laundry at the same time, due to the difference in the attachment position of the pinch to the frame, the tension of the non pinched when taking in the laundry every pinch The direction is changing. In the clothes-drying tool shown in Patent Document 3, since the bending direction is not restricted, the bending direction of the first and second suspension members causes variations in the angle at which the object to be held is pulled, and According to the configuration of the present invention, the pivoting direction of the pivoting connection portion is restricted from pivoting in the direction intersecting with the extending direction of the flexible description member according to the configuration of the present invention, as compared with the portion where it is difficult to join sufficiently. Therefore, even if there is a variation in the angle at which the object to be held such as the laundry is pulled, the force for opening the flexible restricting member 8 can be sufficiently applied.

  The third embodiment for carrying out the present invention shown in FIGS. 10 and 11 mainly differs from the first embodiment for carrying out the present invention in that the magnet 16 in which the rotation restricting portion 10 is formed is used. In the pinch unit 1B configured as described above in that the pinch member 3 is connected to the support member 4B using the support member 4B having the same functions and effects as those of the first embodiment for carrying out the present invention In addition, the pinch unit 1B can be detachably attached to various magnetic articles such as a clothes drying tool having a magnetic frame and a refrigerator.

  In addition, it is good also as a supporting member which can be attached to other articles | goods instead of the supporting member which has magnetic force, such as a supporting member with an adhesion layer.

  Further, although the magnet attached to the support member has been described in the present embodiment, the support member itself may be a magnet.

  The fourth embodiment for carrying out the present invention shown in FIG. 12 and FIG. 13 is mainly different from the second embodiment for carrying out the present invention in that it has a projection-like rotation on the frame of the clothes dryer 14. Even in the pinch unit 1C configured as described above, the same effects and advantages as those of the first embodiment for carrying out the present invention can be obtained in that the support member 4C is used as the support member 4C.

  The present invention is used in the industry to manufacture pinch units.
