Description

The present invention relates to a horizontal shield feather blind that is provided on an upper hook and moves and holds a moving hook up and down, and a shaft of a winding drum of a lifting / lowering string, and a notched hook on a notched hook band hanging from above. The present invention relates to a scissor operating device for rotating a horizontal axis of a scissor movement holding device, such as a shaft of a moving gear in a mobile scissor meshing with a belt.

Conventionally, a moving rod of a horizontal shielding feather blind that is vertically adjusted and held by an elevating string or a thin metal tape that is suspended from a rod moving device provided in an upper fixed rod is generally widely used.

An earlier application of the same applicant as the present application, Japanese Patent Application No. 2003-314148, shows an operation means using a knurled hand band with a heel movement holding device using a knurled band like a toothed belt. Has been. On the horizontal shaft that is rotatably supported in the rod, the rod movement holding device and the operation gear are fixedly provided at a distance from the rod movement holding device.

Japanese Patent Application No. 2003-314148. Japanese Patent Application No. 2004-085819.

In the scissors operating device shown in Japanese Patent Application No. 2003-314148, the slack side of the hand strap is fallen and retracted due to the weight of the detent piece disengaged from the strap when the scissors are moved. It is pushed into the hollow surface of the case by force. Therefore, when pulling up the kite in a hurry, the slack side of the hand strap is pulled downward due to the inertia resistance of the strap due to its rapid movement, resistance due to contact, etc., so that the return stop is pushed forward unexpectedly. Thus, there may be a problem such that the tooth surface formed on the front side of the detent piece comes into contact with the inner surface on the pulling side of the hand strap. Therefore, if the force in the direction in which the return stop piece falls and retreats is increased by using a spring or the like, there is a limit because the return stop piece is easily detached.
An object of the present invention is to provide a scissor operating device capable of a detent operation that is reliable and stable without being affected by the moving speed of the operating band in view of the drawbacks of the scissor operating device as described above. It is.

In order to achieve the above object, the present invention provides a horizontal shielding feather blind including a horizontal shaft that is rotatably supported in a housing and is partially connected to a heel movement holding device.

It is characterized in that a stop piece is hung by the stop operation portion of the operation band.
Here, in (1), the fact that rotation is coupled to the horizontal axis via at least... Means that the operation gear is directly fixed to the horizontal axis and coupled to rotation. is there. In addition, in (2), the operating band may be separated from the hanging part on the pulling side and the hanging part on the other slack side, but it is preferable that the operation band be joined in a ring shape or a ring shape as much as possible. .
Further, in (3), the guide means for the stop piece can be arbitrarily selected by those skilled in the art, such as an arm part that is rotatably supported by the support shaft, or a guide groove formed in the case and a convex part of the stop piece that fits into the guide groove. It can be selected and provided.
Further, the stopping means of the stopping piece in (4) is a means for applying a force for retracting the stopping piece using an elastic body such as its own weight or a spring, that is, a force in the releasing direction. Any choice can be made.

To achieve this.

The blind of the horizontal shielding wing shown in FIGS. 1 to 3 is provided with a horizontal shaft 9 having a square shaft section rotatably supported by the bearing 7 and the bearing of the rod operating device 8 in the upper rod 1. There is provided a scissor operating device 8 including a scissor movement holding device 6 and a scissor stopping means provided in parallel therewith. On the horizontal shaft 9, the pair of cylinders 10 are connected to the position corresponding to the band 3 so that the pair of cylinders 10 can slide on the horizontal axis through the rectangular holes of the shaft center and rotate simultaneously with the shaft. The heel band 3 is a toothed belt having a notch on its surface side, and its lower end is coupled to the moving ridge 2. The upper side of the cylinder 10 is wound around the outer periphery of the cylindrical body 10 in a spiral manner and then unwound to move the moving rod 2 in parallel, and the rod moving and holding device 6 is configured to hold it in parallel. . The horizontal shielding wings 5 are held by a pair of wing holding strings 4 suspended from the wing operating means 33 of the friction ring fitted on the cylinder 10 in the upper rod 1 and the moving rod 2 is formed, and the shielding adjustment surface A is formed. Yes. On the right side of the horizontal shaft 9, there is an operation case 11 of the rod operating device 8 fixed to the upper rod 1, and an operation gear 13 having a support shaft 12 that fits freely in the operation case 11 is provided. A small gear 25 is integrally formed at the left end of the operation gear 13. The small gear 25 is meshed with an internal gear 35 that is tightly fitted to a gear boss 19 fixed to the right end of the horizontal shaft 9, and the horizontal shaft 9 is connected to the rotation. An operation band 14 of a toothed belt connected in a ring shape is engaged with and wound around the operation gear 13. The portion of the operation band 14 that hangs down from the front side of the operation gear 13 becomes the moving operation unit 15 on the pull side where the weight of the rod is heavy when the rod is operated. On the other hand, the portion that hangs down the rear side of the operation gear 13 forms a stop operation portion 16 on the slack side that hangs down through the guide surface 23 of the push lever 22. In the space below the operation gear 13, there is a stop piece 17 that swings back and forth. The stopper piece 17 is integrally formed so as to protrude toward the operation gear side at the end of the arm portion 20 that is freely swingably fitted to the support shaft 12 portion on the right side of the operation gear 13 via a bearing. It is guided by the part 20 and swings around the horizontal axis 9. The stop piece 17 is formed with a hook tooth surface 18 that meshes with the notch of the operation band on the front side surface, and a pressing surface 19 of the pushing lever is formed on the rear side. The stop piece 17 is retracted by its own weight when the hooking tooth surface 18 is disengaged from the notch of the operation band. A lever pin 21 that is horizontally fixed to the left and right of the operation case 11 is provided below the stopper piece 17, and an extrusion lever 22 that is rotatably supported by the lever pin 21 is provided. The push lever 22 has a convexly curved band guide surface 23 that receives the hanging portion on the rear side of the operation band 14 and guides it downwardly on the front side of the pin hole. A lever portion 26 having a pushing portion 24 is provided at the extended position. Here, the pushing portion 24 is formed in a lateral pin shape. The coil portion is fitted into the portion of the lever pin 21 that supports the push lever 22, one leg is inserted below the belt guide surface 23 of the push lever, and the other leg is received by the lower part of the operation case 11. There is a return spring 29 for lever return means. Therefore, as shown in the drawing, the pushing lever 22 is always kept in a state where the lever portion 26 hits the rear wall of the operation case 11 and rises backward. In the operation case 11, a front wall surface 27 extending downward is formed in the front portion of the operation gear 13. The front wall surface 27 functions as a receiving surface for holding the operation band 14 and holding it between the hooking tooth surface 18 when the hooking tooth surface 18 of the stopper piece 17 pushes the operation band 14. An inner guide wall 28 of the inner guide means is formed in the lower part of the movement space of the stop piece 17 and its front end surface protrudes somewhat forward from the hook tooth surface 18 when the stop piece is retracted. The inner guide means is not absolutely necessary, but serves to prevent the inner side from coming into contact with the tooth surface 18 when the movement operation unit 15 is not sufficiently inclined during the heel movement operation. It also serves to prevent the inside of the hanging part on the pulling side of the operation band and the hanging part on the slack side.
In the state shown in FIG. 2, when the moving operation unit 15 of the operation band 14 is pulled downward as indicated by an arrow 30, the stop piece 17 moves backward with its hook tooth surface 18 removed from the notch of the operation band 14. The surface 19 is kept in a position where it hits the pushing portion 24. Then, the operation gear 13 rotates in the direction of the arrow to rotate the internal gear 35 in the direction of the arrow, and rotates the cylinder 10 through the horizontal shaft 9 to move the band 3 and the moving rod 2 upward as indicated by the arrow 31. . If the moving operation unit 15 is returned upward, the moving rod 2 moves downward with its weight. Thus, the moving rod 2 can be moved up and down by operating the movement operation unit 15. When the stop operation unit 16 is pulled downward as indicated by an arrow 32 while the movement operation unit 15 is kept in that position, the band guide surface 23 of the push-out lever 22 is moved by the return spring 29 as shown by an imaginary line in FIG. The force is overcome and tilted downward, and the pushing portion 24 pushes the stopper piece 17 forward. Then, the hanging tooth surface 18 of the stopper piece 17 presses the operating band 14 against the front wall surface 27 while engaging the notch. By loosening the pulling force on the moving operation unit 15 side while keeping the stop operation unit 16 side in that state, the operation band 14 strongly pulls the stop piece 17 upward by the weight of the moving rod 2 side and It locks itself between the hanging tooth surfaces 18. In this way, the moving rod 2 is held at that position. By finely operating the movement operation unit 15 side and the stop operation unit 16 side, the moving rod 2 can be finely moved. The inclination of the horizontal shielding wing 5 can be finely adjusted by finely moving the wing operating means 33 fitted on the cylinder 10. As a result, regardless of the speed of the moving operation by the moving operation unit 15, the lever portion 26 of the push-out lever is maintained in the state of rising backward by the force of the return spring 29, and the detent operation is stable and stable in operation. Can be obtained.

FIGS. 4 to 5 show another embodiment, in which a moving rod 2a is fixed on a horizontal shaft 9a supported on a frame in a freely movable manner on a set of rod bands 3a suspended from the upper portion. A moving gear 34 that meshes with the band 3a is provided, and a rod movement holding device 6a that moves and holds the rod 3a via the moving gear 34 is provided. The saddle operating device 8a shown here is basically the same as that described above except for the gear transmission mechanism portion between the operating gear 13a and the horizontal shaft 9a. In the following description of the embodiments, the same parts as those in the above-described example are denoted by the same reference numerals with a, b, and c suffixes, and detailed description thereof will be omitted, and different parts will be mainly described. An operation gear 13a is provided on a support shaft 12a fixed in the operation case 11a. A small gear 25a is integrally formed on the left side of the operation gear 13a. The small gear 25a is meshed with a large gear 35a that is tightly fitted on the horizontal shaft 9a at the same position, and the operation gear 13a is coupled to the horizontal shaft 9a so that the rotation direction is opposite to each other. Yes. Therefore, when the moving operation portion 15a of the operation band 14a is pulled downward as indicated by an arrow 30a, the stopper piece 17a is moved away from the operation band 14a. The operation gear 13a rotates in the direction of the arrow and rotates the large gear 35a and the horizontal shaft 9a in the direction of the arrow. The moving gear 34 rotates with the rotation of the horizontal shaft 9a, and the moving rod 2a moves upward on the rod band 3a as indicated by an arrow 31a.竿 Moving operation and detent operation are the same as the previous example. Here, the inner guide means is composed of an inner guide roller 28a fitted to a pin fixed horizontally in the operation case 11a, and the contact movement of the moving operation portion 15a of the operation band is smoother.

6 to 7 show an embodiment in which the operating gear of the eaves operating device is directly fixed to the horizontal axis of the upper eaves and is rotationally connected. The saddle operating device 8b has an operating gear 13b fixed on the horizontal shaft 9b in an operating case 11b fixed to the upper flange 1b. Guide walls 20b extending in a key groove shape in the direction of movement of the stopper piece are provided on the walls of the left and right operation cases 11b of the movement space of the stopper piece 17b formed under the operation gear. On the other hand, the left and right side surfaces of the stopper piece 17b are provided with key-shaped guide protrusions 19b that fit into the guide grooves 20b, and a guide means for the stopper pieces is formed. Therefore, the stop piece 17b moves back and forth while being guided by the guide groove 20b in the movement space. Here, the pushing lever 22b has lever returning means of a return weight 29b extending rearward on the rear side of the pin hole. The return weight 29b also serves as a detent when it comes into contact with the upper surface of the bottom wall of the upper flange 1b when the push lever is fully inclined rearward. The saddle movement holding device 6b shown here is provided with a set of winding gears 34b fixedly at a position facing the collar band 3b on the horizontal shaft 9b, and the lower side of the winding gear 34b is coupled to a moving rod. The belt 3b is wound so as to hang down from the rear side to the front side. Therefore, the moving rod moves up and down and stops by rotating and stopping the horizontal shaft 9b. The details of the heel movement operation and the detent operation are the same as in the previous two examples.

FIG. 8 shows an embodiment in which the operation gear of the rod operating device is attached to the front surface of the upper rod at a right angle to the horizontal axis. A support shaft 12c is fixed to the operation case 11c fixed to the front portion of the upper rod 1c in a direction perpendicular to the horizontal shaft 9c, and the operation gear 13c is freely fitted to the support shaft 12c. A small bevel gear 25c is integrally formed on the rear side of the operation gear 13c and meshes with a large bevel gear 35c fixed on the horizontal shaft 9c. Therefore, when the moving operation portion 15c of the operation band 14c is pulled downward as indicated by an arrow 30c, the stop piece 17c is moved away from the operation band 14c and retreated, and the operation gear 13c is rotated in the direction of the arrow to be level with the large bevel gear 35c. The shaft 9c is turned in the direction of the arrow. The cylindrical body 10c, together with the horizontal shaft 9c, winds up the heel band and raises the moving rod coupled to the lower part thereof. Thus, the moving rod moves up and down and stops by rotating and stopping the horizontal shaft 9c. The details of the heel movement operation and the detent operation are the same as in the previous example.
The kite operation device of the present invention operates the kite movement holding device by providing an operation gear directly on the horizontal axis of the kite movement holding device or on another shaft and connecting the rotation via an arbitrary transmission mechanism. You can do that.

The scissor operating device of the present invention is widely used in horizontal shielding blade blinds equipped with a scissor movement holding device of a method in which a scissor band is wound around a cylinder or the like, or the scissors themselves move on the scissors band by a moving gear or the like.
