Description

  The present invention relates to a structure for attaching a blind operation cord to a lower plate for detachably attaching an operation cord for operating a blind shielding material to the lower plate.

  As a conventional structure for attaching a blind operating cord to a lower plate, a structure described in Patent Document 1 is known. According to this, the permanent magnet is built in the end button attached to the tip of the operation string, and the bottom plate of the blind is formed from the steel plate, so that the end button is attracted to the lower plate by the permanent magnet. Can be done. If the operation cord is operated while the end button is adsorbed on the lower plate and this adsorbed state is maintained, the operation cord can be suspended in a folded state even when the blind is pulled up to the uppermost position. The operating string does not hang down for a long time, and the operating string can be kept out of the way even when the blind is rolled up.

  However, in the mounting structure described in Patent Document 1, since it is assumed that the end button is always attracted to the lower plate, it is assumed that the length of the operation string is always a length that can be attracted to the lower plate. It has become. Therefore, the length of the operation string has a certain length, and there is a problem that when the end button is removed from the lower plate, the amount of hanging of the operation string becomes very large.

  In addition, in the mounting structure described in Patent Document 1, it is conceivable to shorten the length of the operation string so that the end button can be freely detached from the lower plate. When removed, there is a problem that the end button may be attracted to an unintended object due to the influence of the surrounding magnetic material.

  For example, when the blinds are built inside the internal window or in the double sash, the end buttons approach the frame or the shovel of the shoji. There is a problem that the end button is attracted, the end button is pulled when opening and closing the shoji and the window, the blind flutters, and contacts the surroundings.

  SUMMARY OF THE INVENTION The present invention has been made in view of such a problem. To the lower plate of the blind operation cord, the operation cord for operating the blind shielding material is detachable from the lower plate without being affected by the surrounding magnetic body. It is an object of the present invention to provide a mounting structure.

In order to achieve the above-described object, the present invention is such that the shielding material is suspended from the head box, the lower plate is provided at the lower end of the shielding material, and the operation cord is suspended from the head box to operate the shielding material. A structure for attaching the blind operation cord to the lower plate,
A magnet is provided on the lower plate, and a magnetic body is provided at the end of the operation cord. By attaching the magnetic body at the end of the operation cord to the lower plate magnet, the end of the operation cord is attached to and detached from the lower plate. It can be freely attached.

Further , the lifting / lowering cord is suspended from the head box, and one end of the lifting / lowering cord is connected to the lower end or the lower plate of the shielding material, and the other end of the lifting / lowering cord passes through the head box and is led out from the head box. An operation cord is provided, and a cord stopper is provided at the other end of the lifting / lowering cord.

Further , the lower plate is provided with means for representing the position of the magnet to the outside.

Furthermore , a buffer material is attached to the lower plate, and the magnet is built in the buffer material.

Further , positioning means for restricting the movement of the magnet in the front-rear and left-right directions is provided inside the shock-absorbing material, and the magnet is fixed so that it cannot be detached from the shock-absorbing material and the lower plate by attaching the shock-absorbing material to the lower plate. It is characterized by that.

Furthermore , the buffer material has a permeable member, and the magnet can be visually recognized from the outside through the permeable member.

  According to the present invention, since the magnet is provided on the lower plate and the magnetic body is provided at the end of the operation cord, the operation cord can be detachably attracted to the lower plate. Can be reduced. Further, when the operation cord is removed from the lower plate, the operation cord can be prevented from being influenced by the surrounding magnetic body.

In addition , the amount of drooping of the operation cord changes according to the raising and lowering of the shielding material, but even if the amount of drooping of the operation cord from the head box is reduced by raising the shielding material, the operation cord is affected by the surrounding magnetic material. It is possible to prevent the blind from being beaten.

Furthermore , since the position of the magnet can be recognized from the outside by the means for indicating the position of the magnet to the outside, the magnet and the magnetic body can be easily aligned when the operation cord is attached to the lower plate.

Furthermore , the shock absorbing material can alleviate the generation of impact sound when the lower plate comes into contact with the sash frame or the shoji, and the magnet can be provided on the lower plate at the same time by attaching the shock absorbing material to the lower plate. As a result, the number of processing steps can be reduced.

Furthermore , by attaching the buffer material to the lower plate, the magnet can be fixed to the buffer material and the lower plate so as not to fall off.

Furthermore , the position of the magnet can be confirmed from the outside through the permeable member, and when the operation cord is attached to the lower plate, the magnet and the magnetic body can be easily aligned.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The blind 10 to which the present invention shown in FIGS. 1 and 2 is applied is a horizontal blind, and a ladder cord 14 hangs down from a head box 12 fixed to a window frame or the like by a bracket 11. A large number of slats 16 as shielding members are suspended from the head box 12 in an aligned state in the vertical direction (see FIG. 3).

  A bottom rail 18 as a lower plate is disposed at the lower end of the slat 16 row, and the lower end portion of the ladder cord 14 is fixed to the bottom rail 18 by a cord holder 20. An upper end portion of the ladder cord 14 is attached to a drum (not shown) disposed in the head box 12, and is connected to a rotating shaft 21 (FIG. 5) penetrating the drum so as not to rotate relative to the side end of the head box 12. By rotating the rotary operation dial 22 disposed on the portion (right side in FIG. 1), the ladder cord 14 tilts and the slat 16 can be rotated.

  Further, a plurality of lifting cords 24 for lifting the slats 16 and the bottom rail 18 are suspended from the head box 12. One end of each lifting / lowering cord 24 is connected to the bottom rail 18 through a plurality of rows of slats 16, and the other end of each lifting / lowering cord 24 passes through the head box 12 and is arranged to the side (right side in FIG. 1). Rotated, led out of the head box 12 via a stopper 26 disposed at the end of the head box 12 and collectively connected to a cord stop 28. The other end of the lifting / lowering cord 24 led out from the head box 12 serves as an operation cord. By operating the operation cord or cord stopper 28, the stopper 26 is operated or released, so that the lifting / lowering cord 24 cannot be moved. It is possible to switch between a possible state and a movable state. By such switching operation of the stopper 26, the slat 16 and the bottom rail 18 can be moved up and down and stopped.

  As shown in FIG. 4, the cord stopper 28 provided at the end of the operation cord includes a cord stopper main body 30 to which the other end of the lifting / lowering cord 24 is locked, and a cover 31 that covers the cord stopper main body 30.

  The other end of the lifting / lowering cord 24 is inserted through an insertion hole 30a formed on the proximal end side of the cord stopper main body 30 toward the distal end, and a knot 24a is formed by a space portion 30b provided in the center of the cord stopper main body 30. Then, the cord stopper main body 30 is locked. Since the space 30b is surrounded by the cover 31, the knot 24a is not exposed to the outside. A lateral hole 30c is formed in the distal end side of the cord stopper main body 30 along the width direction thereof, and the lateral hole 30c communicates with the outside on a side peripheral surface which is the distal end side. A columnar magnetic body 32 is inserted into the lateral hole 30 c, and the magnetic body 32 is disposed at the tip of the cord stopper 28 in parallel with the width direction of the cord stopper 28. Since the end portion of the horizontal hole 30 c is closed by the cover 31, the magnetic body 32 cannot be detached from the cord stopper 28.

  An arbitrary number of cushioning members 34 are attached to arbitrary positions where the cord holder 20 of the bottom rail 18 is not disposed. The cushioning material 34 is for reducing the generation of impact sound when the bottom rail 18 abuts against a window frame or the like. The at least one cushioning material 34 is provided with a cord stopper provided with the magnetic body 32. A magnet 36 for adsorbing 28 is incorporated.

  More specifically, as shown in FIGS. 6 to 8, the inner surface of the cushioning material 34 matches the lower surface and the front and rear surfaces of the bottom rail 18 so as to surround the lower surface and the front and rear surfaces of the bottom rail 18. A protrusion 34a is formed on the inner surface of the front and rear sides of the cushioning material 34 over the entire length. As shown by the arrow in FIG. 7, the protrusion 34 a is slidably fitted in a rail-like recess 18 a formed on the front and rear surfaces over the entire length of the bottom rail 18. Further, a positioning portion 34b (positioning means) recessed in a columnar shape is formed on the inner surface on the bottom side of the cushioning material 34, and a columnar magnet 36 can be fitted into the positioning portion 34b.

  The shock absorber 34 is attached to the bottom rail 18 by fitting the recess 18a of the bottom rail 18 and the protrusion 34a of the shock absorber 34 from the side end of the bottom rail 18 as shown by the arrows in FIG. This is done by sliding the material 34 in the longitudinal direction of the bottom rail 18. Further, the cushioning material 34 provided on the side close to the operation cord is attached to the bottom rail 18 with the magnet 36 fitted in the positioning portion 34b in advance. Thereby, as shown in FIGS. 3B and 5, the magnet 36 is accommodated between the bottom surface of the bottom rail 18 and the positioning portion 34 b of the cushioning material 34, and the front, rear, left, right, and downward directions are positioned by the positioning portion 34 b. In the upward direction, the movement is restricted by the lower surface of the bottom rail 18, so that the magnet 36 is fixed so as not to fall off the cushioning material 34 and the bottom rail 18. As a result, the magnet 36 can be provided on the bottom rail 18 at the same time when the cushioning material 34 is attached to the bottom rail 18, and the number of processing steps can be reduced.

  Means for expressing the position of the magnet 36 to the outside may be provided so that the position of the magnet 36 attached to the bottom rail 18 can be seen from the outside.

  For example, one example of the means is to configure at least a part of the cushioning material 34 with a transparent or translucent transparent member. Thereby, the magnet 36 built in the buffer material 34 can be visually recognized through the buffer material 34 from the outside. Another example is to mark the outer surface of the bottom corresponding to the positioning portion 34b of the cushioning material 34 instead of configuring the cushioning material 34 with an impermeable member. As a further example, the positioning portion 34b of the cushioning material 34 can be communicated with the outside so that the magnet 36 can be directly visually recognized from the outside.

  As shown in FIG. 8, the magnetic body 32 is opposed to the position of the magnet 36 recognized from the outside, and the cord stopper 28 is brought into contact with the buffer material 34 as shown in FIG. The cord stopper 28 can be detachably attached to the bottom rail 18.

  Next, based on FIG.1 and FIG.2, operation | movement of the blind 10 which implemented this invention is demonstrated.

  As shown in FIG. 1, in order to raise the slat 16 and the bottom rail 18 from the state where the slat 16 and the bottom rail 18 are lowered to the lowest position, the cord stopper 28 is operated to release the stopper 26 and move up and down. The cord 24 is made movable, the cord stopper 28 is lowered, and the operation cord on the other end side of the lifting / lowering cord 24 hanging from the head box 12 is lowered. By being pulled by this, one end of the lifting / lowering cord 24 rises, so that the bottom rail 18 rises and the slat 16 is folded up. When the operation is stopped after being folded up to an arbitrary position, the stopper 26 is actuated to restrain the elevating cord 24 and the bottom rail 18 and the slat 16 can be stopped at that position.

  As shown in FIG. 2, when the slat 16 and the bottom rail 18 are raised to the highest position, the amount of the operation cord that is the other end of the lifting / lowering cord 24 hanging from the head box 12 increases. Therefore, when the tip of the cord stopper 28 is directed upward and brought into contact with a position where the magnet 36 of the buffer material 34 is located, the magnetic body 32 of the cord stopper 28 is attracted to the magnet 36 of the buffer material 34 and the amount of drooping is reduced. It can be reduced to about ½, and the lifting / lowering cord 24 can be prevented from getting in the way.

  The suction of the cord stopper 28 to the cushioning material 34 can be performed only when the slat 16 is completely raised, and the tip of the cord stopper 28 is placed at a position where the magnet 36 of the cushioning material 34 is located. Any height position can be used as long as the height can be brought into contact.

  Further, as shown in FIG. 2, in order to lower the slat 16 and the bottom rail 18 from the state where the slat 16 and the bottom rail 18 are raised to the highest position, the cord stopper 28 is attached from the cushioning material 34 as necessary. The cord 26 is removed and the stopper 26 is released by operating the cord stopper 28 so that the lifting / lowering cord 24 is movable, and the bottom rail 18 and the slat 16 are lowered by their own weight. At this time, since one end of the lifting / lowering cord 24 connected to the bottom rail 18 is also lowered, the other end of the lifting / lowering cord 24 is lifted by this, and the cord stopper 28 is raised to a position close to the head box 12. To do. When the bottom rail 18 and the slat 16 are lowered to an arbitrary position, the cord stopper 28 is operated to operate the stopper 26, whereby the lifting cord 24 is restrained and the bottom rail 18 and the slat 16 are stopped at that position. Can do.

  In the state shown in FIG. 1, the hanging amount of the operation cord on the other end side of the lifting / lowering cord 24 is reduced, and therefore the cord stopper 28 is removed from the bottom rail 18. Since the cord stopper 28 is only provided with the magnetic body 32 instead of the magnet, the operation cord is affected by the surrounding magnetic body when the cord stopper 28 is not restrained by the bottom rail 18 in this way. Can not be.

  9 and 10 show an example in which a blind to which the present invention is applied is attached to a window frame.

  The blind 10 is disposed in a space 44 between the inner window 40 and the outer window 42, and the head box 12 is attached to the upper window frame 46 of the inner window 40 by the bracket 11. As shown in FIG. 9, in a state where the bottom rail 18 is lowered to the lowest lowered position, the cord stopper 28 is removed from the bottom rail 18 and is located at a position close to the head box 12. Although the cord stopper 28 is located closer to the inner window 40 than the slats 16, the cord stopper 28 is provided only with the magnetic body 32, and thus is arranged inside the vertical frame such as the window frame or the inner window 40. The blind 10 is not blown when the inner window 40 is opened or closed because it is not affected by and attracted to the magnetic part such as the metal cage. On the contrary, since the magnet 36 is provided on the bottom rail 18, the magnet 36 of the cushioning material 34 and the lower window frame 48 approach each other when the bottom rail 18 is lowered to the lowest position. Is sucked or adsorbed by the lower window frame 48, and the effect of preventing the blind 10 from swinging can be obtained. Since the magnet 36 is located on the lower surface side rather than the front and rear surface side of the bottom rail 18, the bottom rail 18 is not affected by the magnetic material from the front and rear direction of the bottom rail 18 and the bottom rail 18 is stopped at an intermediate height. The blind 10 is not beaten even if the inner window 40 is opened and closed.

  Further, as shown in FIG. 10, when the slat 16 is raised, the magnetic body 32 provided on the cord stopper 28 is attracted to the magnet 36 provided on the bottom rail 18, so that the cord stopper 28 is attached to the lower surface of the bottom rail 18. The operation cord which is the other end side of the lifting / lowering cord 24 can be suspended in a folded state, and the amount of the suspension can be reduced.

  In the above example, a horizontal blind is used as a blind. However, any blind (for example, a roman shade, a pleated screen, and other blinds) can be used, and one end of the lifting / lowering cord is a shielding material. You may make it connect with the lower end of. Further, instead of using the operation code as a part of the lifting / lowering code, the operation code and the lifting / lowering code may be separate codes.
