(Safety equalizer of Example 1)
Hereinafter, the safety equalizer 6 according to the first embodiment will be described with reference to FIGS. 2 to 7. FIG. 2 is a perspective view showing a schematic configuration of the safety equalizer 6 of Example 1 in the horizontal blind according to the embodiment of the present invention. Here, the X-axis direction shown in FIG. 2 indicates the indoor direction of the horizontal blind, the Z-axis direction indicates the left direction of the horizontal blind, and the Y-axis direction indicates the upward direction of the horizontal blind. In FIG. 2, it is possible to configure a horizontal blind that raises and lowers the slat 3 with two lifting cords C1 and C2, and for example, a horizontal blind that lifts and lowers the slat 3 with four lifting cords C1, C2, C3, and C4 An example is shown. That is, in the safety equalizer 6 of the first embodiment shown in FIG. 2, when the horizontal blind for raising and lowering the slat 3 with the two lifting cords C1 and C2 shown in FIG. 1 is used, the lifting cords C3 and C4 are not used. And it is sufficient.

  The safety equalizer 6 according to the first embodiment shown in FIG. 2 is formed of a pair of locking members 6a and 6b that are pivotally supported around a support shaft 61 so as to be opened and closed. The pair of locking members 6a and 6b are configured in the same shape, and are provided with a locking portion 65 that holds the ends of the plurality of lifting / lowering cords C1, C2, C3, and C4 above the support shaft 61 and locks them. ing. A rotation suppressing portion 64 that suppresses the rotation of the pair of locking members 6a and 6b is formed below the support shaft.

  The rotation suppressing portion 64 is formed with a grip portion 63 that can be gripped at the side portion and can be gripped at the upper end portion. For example, the operator holds the grip part 63 with the index finger and has the side part of the rotation suppression part 64 with the thumb or other fingers, or the side part of both rotation suppression parts 64 and rotates. The suppression unit 64 can be gripped.

  The rotation suppression unit 64 has a structure that can lock one end of the operation cord 7 at the lower end thereof. For example, one end of the operation cord 7 is locked and suspended by the knotting ball 7a at the lower end of the rotation suppression unit 64. The other end of the operation cord 7 is suspended from the safety equalizer 6 and attached to the bottom rail 4 via the safety joint 8 (see FIG. 1).

  A cylindrical binding tool 62 is inserted into one end of each of the plurality of lifting / lowering cords C1, C2, C3, C4, and each binding tool 62 is locked by a knotting ball of each lifting / lowering cord C1, C2, C3, C4. ing. When the pair of locking members 6a and 6b constituting the safety equalizer 6 are in the closed state (the state shown in FIG. 2), the binding tools 62 of the plurality of lift cords C1, C2, C3, and C4 are located above the support shaft 61. It is pinched and locked by a locking portion 65 formed on the surface.

  FIG. 3 is an exploded perspective view illustrating a schematic configuration of the safety equalizer 6 according to the first embodiment. The pair of locking members 6a and 6b are configured in the same shape, and face each other alternately, and the support shaft 61 is inserted into the shaft hole portion 66 provided in each of the locking members 6a and 6b to be locked. As a result, the safety equalizer 6 is integrated.

  And the rotation suppression part 64 has the cavity part 67, The semicircle-shaped locking piece 68 which stands up from the inner bottom face of the rotation suppression part 64 is provided in the cavity part 67, and the locking piece 68 is an operation code. 7 has a locking hole 69 that can be inserted through the knotting ball 7a. In addition, an elongated insertion hole 70 through which the operation cord 7 can be inserted is provided on the bottom surface of the rotation suppressing portion 64. Therefore, for example, the operation cord 7 locked in the locking hole 69 of the locking piece 68 in the locking member 6b is inserted into the locking hole 69 of the locking piece 68 in the locking member 6a by the knot 7a. Thereafter, the locking member 6a is inserted into the long hole-like insertion hole 70 and hangs downward (see FIG. 2). Since the pair of locking members 6a and 6b have the same shape, any of the locking members 6a and 6b can lock the operation cord 7 and hang downward. The pair of locking members 6a and 6b are not limited to the example having the same shape, but other structures may be used as a structure in which the operation cord 7 can be locked and suspended downward. In the case of an application that does not need to be locked, the locking piece 68, the locking hole 69, and the insertion hole 70 may not be provided.

  In addition, when the pair of locking members 6a and 6b are not the same shape, the support shaft 61 is not a separate member, and can be configured to extend from either one of the pair of locking members 6a and 6b.

  Each end of the plurality of lifting / lowering cords C1, C2, C3, C4 is sandwiched and locked by a locking portion 65 formed above the support shaft 61 in a closed state of the pair of locking members 6a, 6b. Therefore, the shape of each locking part 65 in the pair of locking members 6a and 6b is a semi-long hole.

  In particular, a cylindrical binding device 62 attached to each end of the plurality of lifting / lowering cords C1, C2, C3, and C4 can be accommodated above the support shaft 61 in a closed state of the pair of locking members 6a and 6b. A space part is provided. As will be described in detail later, the elevating cords C1 and C2 are sandwiched and locked by a long locking common locking portion 65 provided in the upper center side and extending in the Z-axis direction ( When tension is applied between the lifting / lowering cords C1 and C2, a rotational torque is applied so that the pair of locking members 6a and 6b are opened. On the other hand, when the elevating cords C3 and C4 are provided, they are sandwiched and locked by individual locking portions 65 each having a semi-long hole extending in the X-axis direction provided at both ends of the upper part. 2 (see FIG. 2), when tension is applied between the lifting / lowering cord C3 and another lifting / lowering cord (or between the lifting / lowering cord C4 and another lifting / lowering cord), it is provided on the inner wall surface forming the space portion. The tension receiving portion 71 is configured to receive the tension related to the binding tool 62 on the inclined surface. This inclined surface is formed by a plane on the Y axis that is located approximately 45 degrees from the X and Z axes, and when the lifting cords C3 and C4 are tensioned in the X axis direction or the Z axis direction, a pair of locking members 6a. , 6b is set to be in an open state so that rotational torque works.

  FIGS. 4A and 4B are explanatory diagrams illustrating the operation of the safety equalizer 6 according to the first embodiment when the safety equalizer 6 is in the closed state. As shown in FIG. 4A, when the operation cord 7 is pulled downward during the raising / lowering operation of the bottom rail 4, the tension F <b> 1 acts on the operation cord 7. Then, as shown in FIG. 4B, the operation cord 7 is inserted into the long hole-like insertion hole 70 in the locking member 6a while being locked to the locking piece 68 in the locking member 6b by the knot 7a. Since the pair of locking members 6a and 6b are closed based on the support shaft 61, the rotational torque T2 acts. Accordingly, a rotational torque T1 acts in a direction in which the pair of locking members 6a and 6b are closed based on the support shaft 61, and therefore, a knot ball 62a is attached to each end of the plurality of lift cords C1, C2, C3, and C4. The cylindrical tying member 62 attached in (1) is sandwiched and locked by the respective locking portions 65.

  When the safety equalizer 6 is gripped and a pulling operation is performed, the force F2 that directly closes is applied, so that the rotational torques T1 and T2 are applied in the same manner as described above. , C3, and C4, a cylindrical binding device 62 attached to each end by a knotting ball 62a is sandwiched and locked by the respective locking portions 65.

  Therefore, in the safety equalizer 6 of the first embodiment, when the safety equalizer 6 or the operation cord 7 is gripped and pulled, the locking portion 65 is closed by the “lever principle” and the plurality of lifting / lowering cords C1, C2, The force which clamps and locks one end of C3 and C4 works. Since the force to pinch and lock each end of the plurality of lifting / lowering cords C1, C2, C3, and C4 works, each end of the plurality of lifting / lowering cords C1, C2, C3, and C4 is not opened, so that the operability is excellent. It has a form.

  On the other hand, FIGS. 5A, 5 </ b> B, and 5 </ b> C are explanatory diagrams illustrating the operation of the safety equalizer 6 according to the first embodiment when the safety equalizer 6 is in the open state. As shown in FIG. 5A, for example, when the bottom rail 4 is at the upper limit position and the plurality of lifting / lowering cords C1 and C2 are suspended from the head box 1 for a long time, foreign matter is interposed between the plurality of lifting / lowering cords C1 and C2. Consider the case where Ob is caught. In this case, as shown in FIG.5 (b), tension | tensile_strength F3 acts on each of several raising / lowering cord C1, C2. Then, a component force F3z in the Z-axis direction is applied to the locking portion 65 that has locked the plurality of lifting cords C1 and C2 in the direction in which the locking portion 65 is opened. As a result, as shown in FIG. 5 (c), the pair of locking members 6a and 6b rotate relative to each other in the K direction to release the locking portion 65 based on the support shaft 61 of the safety equalizer 6. The cylindrical tying member 62 attached by the knotting balls 62a of the cords C1 and C2 is released from the released locking portion 65, and the load on the foreign object Ob is removed.

  Further, even when the safety equalizer 6 is in the open state as described above, the pair of locking members 6a and 6b are not individually separated and are not further detached from the operation cord 7. For this reason, when the foreign object Ob is removed and the safety equalizer 6 is reconfigured, the operation cords for attaching one end to the bottom rail 4 and the ends of the plurality of elevating cords C1 and C2 suspended from the head box 1 7 has a structure that can be easily rebound using the pair of locking members 6a and 6b that are attached to the other end of the member 7, and there is no possibility of losing the members.

  Further, as shown in FIG. 6 (a), even if the foreign object Ob is applied only to one lifting / lowering cord (for example, the lifting / lowering cord C2) and the posture of the safety equalizer 6 is in the horizontal direction, it is shown in FIG. 6 (b). As described above, a force F3 ′ is applied to the locking portion 65 that has locked the plurality of lifting cords C1 and C2 in the direction in which the locking portion 65 is opened. As a result, as shown in FIG. 6 (c), the pair of locking members 6a and 6b rotate relative to each other in the K direction to release the locking portion 65 based on the support shaft 61 of the safety equalizer 6. The cylindrical tying member 62 attached by the knotting balls 62a of the cords C1 and C2 is released from the released locking portion 65, and the load on the foreign object Ob is removed.

  The space above the support shaft 61 in the closed state of the pair of locking members 6a and 6b has a cylindrical binding device 62 attached to each end of the plurality of lifting / lowering cords C1, C2, C3 and C4. Although it can be accommodated, when a tension acts between the lifting / lowering cord C3 and another lifting / lowering cord (or between the lifting / lowering cord C4 and another lifting / lowering cord), the binding tool 62 related to the tension is received by the inclined surface. A tension receiving portion 71 is provided. For example, in the example shown in FIG. 7, when the lifting / lowering cords C3 and C4 are pulled in the X-axis direction, when the binding tool 62 of the lifting / lowering cords C3 and C4 comes into contact with the inclined surface of the tension receiving portion 71, In order to generate a component force F5 in the Z-axis direction that opens the locking portion 65 in the portion 71, the lifting cords C1, C2, C3, and C4 are similarly opened.

  As described above, according to the safety equalizer 6 of the first embodiment, it is possible to ensure safety when a foreign object is caught between the lifting cords C1, C2, C3, and C4 to be locked. Further, the safety equalizer 6 of the first embodiment is configured in a form that can be gripped for a pulling operation, and has a force to pinch and lock each end of the plurality of lifting cords C1, C2, C3, and C4 during the pulling operation. Since it works, the ends of the plurality of lifting cords C1, C2, C3, and C4 are not opened, and the operability is excellent. In addition, according to the safety equalizer 6 of the first embodiment, the safety equalizer 6 includes the pair of locking members 6a and 6b that are pivotally supported around the support shaft 61 so that the plurality of lift cords C1, C2, C3, and the like. Not only can each end of C4 be separable, but also re-binding after each member such as the locking members 6a, 6b and the lifting / lowering cords C1, C2, C3, C4 has been separated individually. it can.

(Safety equalizer of Example 2)
Next, the safety equalizer 6 of Example 2 is demonstrated with reference to FIG.8 and FIG.9. FIG. 8 is a perspective view showing a schematic configuration of the safety equalizer 6 of Example 2 in the horizontal blind according to one embodiment of the present invention. In addition, the same reference number is attached | subjected to the component similar to Example 1. FIG. Compared to the safety equalizer 6 of the first embodiment, the safety equalizer 6 of the second embodiment has a pair of locking members 6a instead of a structure in which one end of the operation cord 7 can be locked at the lower end of the rotation suppressing portion 64. , 6b is different in that it is fitted in a closed state, and the other components are the same. Therefore, the safety equalizer 6 according to the second embodiment functions as an operation grip for operating the movement of the lifting / lowering cords C1, C2, C3, and C4.

  Also in the safety equalizer 6 of the second embodiment, the safety equalizer 6 is formed of a pair of locking members 6a and 6b that are pivotally supported around the support shaft 61 so as to be opened and closed. The pair of locking members 6a and 6b are configured in the same shape, and are provided with a locking portion 65 that holds the ends of the plurality of lifting / lowering cords C1, C2, C3, and C4 above the support shaft 61 and locks them. ing. Moreover, the rotation suppression part 64 which suppresses rotation of a pair of latching member 6a, 6b below the spindle is comprised. The rotation suppressing portion 64 is formed with a grip portion 63 that can be gripped at the side portion and can be gripped at the upper end portion. For example, the operator can hold the rotation suppressing unit 64 by holding the holding unit 63 with the index finger and holding the side of the rotation suppressing unit 64 with the thumb or other fingers.

  In the example shown in FIG. 8, the pair of locking members 6 a and 6 b are configured in the same shape, and at the lower end of the rotation suppressing portion 64, a fitting protrusion 72 and a fitting receiving portion that can be fitted to each other. 73 is formed.

  FIGS. 9A and 9B are explanatory views showing the opening / closing operation of the safety equalizer 6 according to the second embodiment. As shown in FIG. 9 (a), when the safety equalizer 6 is pulled downward when the bottom rail 4 is moved up and down, a force that directly closes works, so a pair of locking members 6a. , 6b, the fitting projection 72 and the fitting receiving portion 73 are fitted to each other, and a cylindrical binding device 62 is attached to each end of the plurality of lifting cords C1, C2, C3, C4 by a knotting ball 62a. , And are held and locked by the respective locking portions 65. The fitting projection 72 and the fitting receiving portion 73 are not easily detached unless an external force due to a foreign substance or the like is applied.

  On the other hand, for example, when the foreign matter Ob is caught between the plurality of lifting / lowering cords C1 and C2 when the bottom rail 4 is at the upper limit position and the plurality of lifting / lowering cords C1 and C2 are long suspended from the head box 1, FIG. As shown in b), tension acts on each of the plurality of lifting / lowering cords C1 and C2, and the locking portion 65 that has locked the plurality of lifting / lowering cords C1 and C2 has a direction in which the locking portion 65 is opened. Added force.
