An embodiment of a clothespin according to the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view showing a use state of the clothespin according to the present embodiment, FIG. 2 is a perspective view of the clothespin according to the present embodiment, and FIG. FIG. 4 is a diagram illustrating the principle of operation, and FIGS. 5-1 and 5-2 are side diagrams illustrating changes in the operating state.

  The clothespin 10 according to this embodiment has a clothespin shape that is substantially U-shaped as a whole, and the base portions of the passive sandwiching body 20 and the actuating sandwiching body 30 are pivotally supported by a vertically long operation coupling body 40, respectively. In addition, the passive holding body 20 and the operating holding body 30 are separated from each other by rotating the operation connecting body 40 so that the laundry can be held between the holding bodies.

  That is, the passive clamping body 20 is formed in a narrow plate shape, and the left and right brackets 21a and 21b are erected at the base end of the passive clamping body 20 and are pivotally supported on the lower portion of the operation coupling body 40 by the pivot 41 pivoted therebetween. It is connected. Similarly, the operation clamping body 30 is also formed in a narrow plate shape, and the base end thereof is pivotally coupled to the front portion of the operation coupling body 40 via a pivotal support mechanism 31. In addition, each sandwiching body is connected to the operation coupling body 40 so that the shaft support mechanism 31 that is the base end supporting portion of the operating sandwiching body 30 is positioned in front of the pivot 41 that is the base end supporting portion of the passive sandwiching body 20. It is configured.

  With this configuration, as shown in FIGS. 4, 5-1, and 5-2, the operation coupling body 40 is rotated forward about a pivot 41 that is a pivotal support portion with the passive clamping body 20. As a result, the operating sandwiching body 30 gradually approaches the passive sandwiching body 20, the tip portion first comes into contact with the passive sandwiching body 20, then the entire surface comes into contact, and the sandwiching surfaces of each sandwiching body come into contact with each other, and It will be in a state where it can be pinched.

  Here, as shown in FIG. 3, the structure of the shaft support mechanism 31 in the case where the proximal end of the operation clamping body 30 is pivotally coupled to the front portion of the operation coupling body 40 via the shaft support mechanism 31 is a so-called hinge. The left and right brackets 33a and 33b projecting on both sides of the proximal end of the operating clamping body 30 and the support bracket 42 projecting between the front and rear of the operation connecting body 40 are provided via the pivot 31 '. It has a structure that supports and connects.

  As described above, each clamping body is connected to the operation coupling body so that the pivotal support mechanism 31 serving as the pivotal support portion of the operation sandwiching body 30 is positioned in front of the pivot 41 serving as the pivotal support portion of the proximal end of the passive clamping body 20. When the operation connecting body 40 is rotated forward, the operating holding body 30 is superposed on the pressure-bonding surface of the passive holding body 20 by a small rotation operation.

  The operation coupling body 40 is assembled in a vertical state having an angle of about 45 degrees with respect to the passive clamping body 20 from the beginning, and a surface facing the passive clamping body 20 side of the lower half is formed in a semicircular arc shape. However, the semicircular arc-shaped terminal portion forms a flat portion 40 ′ that is formed horizontally and comes into contact with the upper surface of the base end of the passive holding body 20. The connecting body 40 is prevented from rising beyond an angle of 45 degrees. That is, this angle of the operation coupling body 40 indicates an initial setting state in which each clamping body is opened.

  Further, a peripheral wall is erected on the peripheral edge of the upper surface of the operation sandwiching body 30 so that the inside thereof is hollow, and a biasing spring 60 is accommodated therein as will be described later.

  Although the structure which clamps the laundry L is formed by the operation coupling body 40 and each holding body 20 and 30 which were comprised as mentioned above, the operation clamping body 30 is a passive clamping body among these clamping bodies. In order to press-bias 20, an urging operation body 50 for urging the operation clamping body 30 to the passive clamping body 20 to be pressed and separated is arranged on the opposite side of the clamping operation of the operation clamping body 30. In addition, the base end of the biasing actuating body 50 is pivotally connected to the operation connecting body 40. That is, the urging operation body 50 is formed as a narrow plate, and is pivotally connected to the upper end portion of the operation coupling body 40 via a bracket 53 and a pivot 51 that are suspended from the base end. A biasing spring 60 is interposed between the biasing actuating body 50 and the actuating sandwiching body 30. In addition, the position of the pivot 51 serving as the pivot connection between the proximal end of the biasing actuating body 50 and the operation coupling body 40 is greater than the position of the pivot mechanism 31 serving as the pivot coupling connection between the operation clamping body 30 and the operation coupling body 40. Further, the front end of the biasing spring 60 is fixed to the front portion of the biasing operating body 50 via the front fixing portion 63, and the rear end of the biasing spring 60 is the rear portion of the operating sandwiching body 30. Accordingly, the position of the front end of the biasing spring 60 of the biasing actuating body 50 associated with the pivoting operation of the operation connecting body 40, that is, the pivot radius of the front fixing portion 63 is actuated. Since the rear end position of the urging spring 60 of the clamping body 30, that is, larger than the turning radius of the rear fixing portion 62, the urging spring 60 applies the urging force in the separation direction of each operating body at the starting position of the operation coupling body 40. Although it is functioning, the rotation of the operation connecting body 40 In accordance with the operation, the position of the front fixing portion 63 of the urging spring 60 is displaced forward to function in the direction of pulling the urging spring 60, and the urging spring 60 extends to be lower with respect to the operation sandwiching body 30. Thus, the working clamping body 30 is biased in a direction in which it is pressed against the passive clamping body 20 via the rear fixing portion 62. In this way, the operation sandwiching body 30 is pressure-biased in the direction of the passive sandwiching body 20 by the action of the biasing spring 60, and the laundry L interposed therebetween is securely sandwiched.

  A long hole 52 is formed at the rear end of the biasing operating body 50, and a regulating rod 80 is interposed between the long hole 52 and the lower part of the operation connecting body 40. The biasing force that acts in the direction in which the body 50 and the operation clamping body 30 are separated from each other is limited. It should be noted that the biasing actuating body 50 is restricted so as not to rotate more than a certain amount in accordance with the turning operation of the operation connecting body 40, that is, the advance distance is restricted along with the turning, and the passive holding body 20 of the operating holding body 30. You may make it adjust the crimping | compression-bonding degree with respect to.

  Further, a lock mechanism 70 is interposed between the urging actuating body 50 and the passive clamping body 20 to lock the state in which the operating clamping body 30 is pressed by the passive clamping body 20 via the urging actuation body 50. It is configured as possible. That is, the lock mechanism 70 pivotally supports the base end of the engagement lever 70 ′ in the middle of the passive holding body 20, and has a plurality of engagement recesses 71 at the rear edge of the engagement lever 70 ′. The joint recess 71 is configured to be able to engage with an extending portion 51 ′ on the outer side of the pivot 51 that connects the operation connecting body 40 and the biasing operating body 50. The engaging lever 70 'is configured to be urged in the engaging direction as will be described later. Therefore, after the operation coupling body 40 is rotated, the engagement lever 70 ′ is operated to engage the extension portion 51 ′ of the pivot 51 with the appropriate engagement recess 71, so that the biasing actuator 50 is fixed at a certain position. As a result, after the pressing state of the working clamping body 30 is generated via the biasing spring 60, the state is also locked.

  In the figure, reference numeral 74 denotes a pivot for pivotally attaching the proximal end of the engagement lever 70 'to the middle of the passive holding body 20, and 75 denotes a coil spring for biasing the engagement lever 70' in the engagement direction. The urging mechanism can select a leaf spring or other urging member.

  Further, elastic holding members 22 and 32 are stretched on the holding surfaces of the passive holding body 20 and the working holding body 30 to enhance the holding function of the laundry.

  FIGS. 6A and 6B show the biasing spring 60, the holding members 20, 30 and the biasing operating body 50 when the clothespin 10 of the present embodiment is actually used. The upper and lower covers that cover the urging actuating body 50 and the operation connecting body 40 are mounted so that the fingers are not pinched between the operation connecting body 40 and the operation connecting body 40. In other words, an upper cover 100 is provided that integrally covers the entire portion excluding the lower portion of the urging operation body 50, the restriction rod 80 portion at the rear portion thereof, the urging spring 60, and the upper half of the operation coupling body 40. A lower cover 200 is provided to cover the lower half of the operation connecting body 40 from below, and the opening portions of the covers facing each other are provided on one cover opening so as not to hinder the rotating operation of the operation connecting body 40. The width is made wider than the width of the other cover opening so as not to interfere with each other. In addition, a hook 250 is provided on the lower surface of the lower cover 200 so as to be hooked on the clothesline R or the like.

  As shown in FIG. 7A, the clothespin 10 of the present embodiment is preferably approximately the same size as a conventional clothespin, that is, about 60 mm in total length and 12 mm in total width. Even in such a configuration, the clothespin 10 of this embodiment can increase the holding area of the laundry in spite of a compact configuration because the holding area can be 3 to 4 times that of the conventional case. Inadvertent laundry can be prevented from falling.

  In the case of a clothespin used to pinch a relatively light and thin laundry, as shown in FIG. 7B, the size is one third to a quarter of the above size. Even so, the holding force similar to that of a conventional clothespin can be maintained, and the structure can be made more compact.

  The clothespin 10 of the present embodiment is configured as described above, and the operation of the clothespin 10 will be described together with its operation when the clothespin 10 is actually used.

  First, in order to clamp the laundry L, the operation coupling body 40 is in a raised shape and is erected at an angle of about 45 degrees with respect to the passive clamping body 20. In this state, the horizontal flat portion 40 ′ formed on the side edge of the operation coupling body 40 is in contact with the upper surface of the base end of the passive holding body 20.

  And both the operation clamping body 30 and the operation coupling body 40 are open above the passive clamping body 20. In such a state, when the operation coupling body 40 is rotated forward about the pivot 41 while the laundry L is sandwiched between the passive clamping body 20 and the active clamping body 30, from FIG. ), Each component member is displaced.

  In other words, the working sandwiching body 30 is pivoted and lowered in the direction of the lower passive sandwiching body 20, and first, the distal end portion of the working sandwiching body 30 comes into contact with the distal end portion of the passive sandwiching body 20. In this state, if the operation coupling body 40 is further rotated, the proximal end portion of the operation sandwiching body 30 gradually descends and approaches the upper surface of the passive sandwiching body 20, and at the same time, the biasing operation body 50. Also, it moves forward and displaces mainly in the tip direction while rotating downward.

  Such forward displacement of the urging actuating body 50 pulls the urging spring 60, and the actuating clamp 30 is moved in the descending direction via the rear fixing portion 62 at the rear end of the urging spring 60. 20 is pulled and urged toward the upper surface direction.

  In such a state, the operating sandwiching body 30 overlaps the upper surface of the passive sandwiching body 20 and sandwiches the laundry L placed between them, and a pressing state is generated by the biasing force of the biasing spring 60. is doing.

  If the engagement lever 70 ′ is engaged with the extension 51 ′ and locked by the lock mechanism 70 in this state, the operation coupling body 40 is required, and the passive clamping body 20, the actuation clamping body 30, and the biasing actuation body are required. 50 is fixed in a polymerized form, and the holding of the laundry L is completed.

  If necessary, it can be locked and hung on the clothesline R via a hook 250 protruding from the lower cover 200. On the other hand, when the laundry L is taken out after the clothesline is completed, first, a lock mechanism is used. When 70 is released, the tension urging of the urging spring 60 is released and the state shown in FIG. 5B is reached. If the operation coupling body 40 is raised and rotated, the passive clamping body 20 and the actuation clamping body 30 are moved. The space L is opened in the state of FIG. 5-1 (a), and the laundry L can be easily taken out.
