  Thus, since the operation part proposed by patent document 1 is the structure arrange | positioned in an attachment frame, naturally the magnitude | size of an attachment frame becomes larger than an operation part. For this reason, there exists a problem that the operating device containing the attachment frame attached to the outer surface of a glass plate becomes large, looks bad, and also becomes expensive.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a blind operating device that can be reduced in size and improved in design, and can further reduce costs.

In order to achieve the above-described object, one embodiment of the present invention includes an operation unit movably provided on an outer surface of a double-glazed glass plate having a blind disposed therein, and an operation unit and at least the glass plate interposed therebetween. And a driven portion that is movably provided in the multi-layer glass and is provided with a magnet on one of the operating portion and the driven portion, and a magnet or a magnetic body on the other, and by magnetic force through the glass plate In an operating device for a blind that can rotate the rotating shaft of the blind by transmitting the motion of the operating unit to the driven unit using the adsorption force,
A groove portion is formed in the operation portion, and the groove portion extends in the movement direction of the operation portion and is disposed at a position offset from the center line of the operation portion in a direction orthogonal to the movement direction of the operation portion. Also, a magnet or a magnetic body is arranged at a position on the center line side, and guide ribs are provided on the glass plate so as to extend in the moving direction of the operation portion and to be fitted into the groove portion to guide the operation portion. Is characterized in that a stopper for restricting the movement of the operation portion beyond a predetermined amount is formed.

In addition , a guide surface is formed on the guide rib in parallel with the moving direction of the operation portion, and a locking portion that engages with the guide surface is formed in the groove portion of the operation portion, and the operation is performed by engaging the locking portion with the guide surface. The movement of the portion in the direction away from the guide rib is restricted.

In addition , the operation unit is attached to the guide rib from the front side of the glass plate.

Further , the groove portion of the operation portion can be elastically deformed, and the guide rib can be fitted by elastic deformation.

Moreover , the protrusion height dimension from the glass plate surface of an operation part is 5.5 mm or less, It is characterized by the above-mentioned.

  According to the present invention, since the position of the groove portion of the operation portion and the position of the magnet or magnetic body are shifted in the direction orthogonal to the moving direction of the operation portion, the protrusion height dimension of the operation portion can be set small, and the operation portion Can be reduced in size, and the design can be improved. The groove is set to a position offset from the center line of the operation unit in a direction orthogonal to the movement direction of the operation unit, and the magnet or the magnetic body is set to a position on the center line side of the operation unit in a direction orthogonal to the movement direction of the operation unit. Thus, the area facing the magnet or magnetic body of the driven portion can be increased while suppressing the number of parts of the magnet or magnetic body and reducing the cost, and a sufficient attracting force can be generated.

  Further, since the guide rib is fitted into the groove portion and the operation portion is guided by the guide rib, the operation device can be reduced in size and the design can be improved. Furthermore, since stoppers are provided at both end portions of the guide rib, it is possible to prevent the operation portion from falling off from the guide rib.

Embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the multi-layer glass 10 is configured by connecting up and down, left and right spacers 14 in a rectangular frame shape, and sandwiching the front and rear surfaces of the spacers 14 with two glass plates 12. The internal space 16 is defined, and a blind 20 is disposed in the internal space 16.

  The blind 20 includes a frame 22 including an upper frame 22a, a lower frame 22b, and a pair of vertical frames 22c, a rotation shaft 24 that extends horizontally in the upper frame 22a and is rotatably supported, and a rotation shaft on the rotation shaft 24. 24, a rotating drum 25 provided rotatably together with the rotating drum 25, a ladder tape 28 whose upper end is connected to the rotating drum 25 and tilts as the rotating drum 25 rotates, and the ladder tape 28 is supported in an aligned state. A plurality of slats 26, a bottom rail 30 disposed below the row of slats 26, to which the lower end of the ladder tape 28 is connected, and supported by being restricted in elevation within the lower frame 22b, and in one vertical frame 22c And a transmission shaft 32 that extends in the vertical direction and is supported so as to be rotatable and immovable up and down, and a transmission mechanism 34 provided between the transmission shaft 32 and the rotation shaft 24.

  The transmission mechanism 34 is for changing the direction of rotation at each end of the rotation shaft 24 and the transmission shaft 32 extending in directions orthogonal to each other, and is constituted by a bevel gear or a helical gear. The rotation from the transmission shaft 32 is transmitted to the rotation shaft 24. A male screw 32 a is formed on the outer peripheral surface of the transmission shaft 32, and an operating device 40 is provided to rotate the transmission shaft 32.

  The operation device 40 is provided so as to be movable on the outer surface of the glass plate 12 of the multilayer glass 10, and to be opposed to the operation unit 42 with at least the glass plate 12 therebetween and movable in the multilayer glass 10. The driven portion 44 and a guide rib 46 for slidably guiding the operation portion 42 are configured.

  2 to 4, the operation unit 42 is accommodated in a rectangular parallelepiped case 50 including a case main body 52 and a cover 54 fitted to the case main body 52, and a magnet storage portion 50 b of the case 50. And a magnet 56.

  A plurality of protrusions 50 a that protrude in the direction of the glass plate 12 are formed on the surface of the case 50 that faces the surface of the glass plate 12, and the tips of these protrusions 50 a are in contact with the surface of the glass plate 12.

  Further, the case 50 is provided with a fitting portion 50c that extends integrally from one side surface of the case main body 52 and protrudes toward the guide rib 46. The fitting portion 50c is disposed at a position offset from the center line when viewed in the horizontal direction of the case 50 (that is, the direction orthogonal to the moving direction of the operation portion 42). On the other hand, the magnet 56 accommodated in the magnet accommodating part 50b is arrange | positioned in the position containing a centerline.

  In this example, the fitting portion 50c defines a groove portion 50d extending in the vertical direction at two locations on the top and bottom, and a pair of locking portions 50e protruding in directions approaching each other are formed on the inlet side of the groove portion 50d. It is formed. The groove portion 50d can be elastically deformed by changing the distance between the pair of locking portions 50e.

 Since the positions of the magnet housing part 50b for housing the magnet 56 and the groove part 50d are not horizontally overlapped and are shifted in the horizontal direction, the height of the operation part 42 protruding from the surface of the glass plate 12 of the case 50 can be kept low. it can. Preferably, the protruding height of the operation portion 42 from the surface of the glass plate 12 is set to a predetermined dimension or less. This predetermined dimension is a size obtained by adding a gap dimension between different window sashes to the step dimension between the multilayer glass 10 and the window sash when the multilayer glass is used for the sliding window. Is preferably 5.5 mm or less.

  Further, since the magnet storage portion 50b is not divided or divided by the groove portion 50d, a large magnet can be stored in the magnet storage portion 50b, the number of magnets 56 can be reduced, and the cost can be reduced. The area facing the magnet 66 can be increased to generate a sufficient attractive force.

  As shown in FIGS. 3 and 4, the driven portion 44 is disposed so as to be slidable in the vertical direction within one vertical frame 22 c, and includes a case main body 62 and a cover 64 fitted to the case main body 62. A rectangular parallelepiped case 60, a magnet 66 accommodated in the case 60, and a spacer 68 also accommodated in the case 60 are provided. The case 50 of the operation unit 42 and the case 60 of the driven unit 44 have substantially the same size as surfaces facing each other.

  A plurality of projections 60a projecting in the direction of the vertical frame 22c facing each other are formed on the surface of the case 60 facing the vertical frame 22c, and the tips of the projections 60a are in contact with the vertical frame 22c.

  The case 60 is provided with a connecting portion 60 b that extends integrally from one side surface of the case main body 62 and protrudes in the direction of the transmission shaft 32. The coupling portion 60b is formed with a through screw hole 60c in which a female screw 60d is formed and through which the transmission shaft 32 passes, and the male screw 32a of the transmission shaft 32 is screwed into the female screw 60d of the through screw hole 60c. . Accordingly, the transmission shaft 32 that cannot move up and down can be rotated by moving the connecting portion 60b up and down.

  The guide rib 46 is fixed on the surface of the glass plate 12 on one vertical frame 22c by a fixing means such as a double-sided tape, and is at a position opposite to the side where the transmission shaft 32 is located with respect to the driven portion 44, and It arrange | positions so that a longitudinal direction may become parallel to the sliding direction of the driven part 44, ie, a perpendicular direction. The guide rib 46 has a substantially T-shaped cross-sectional shape at portions other than the upper and lower ends, and a T-shaped bottom surface 46 a is fixed to the glass plate 12 surface. Further, the upper and lower ends of the guide rib 46 are stoppers 46b and 46c fixed to the surface of the glass plate 12.

  The groove portion 50d of the operation portion 42 is fitted into the top portion 46d extending in the lateral direction of the T-shape, and the guide rib 46 is formed so that the engagement portion 50e of the operation portion 42 is engaged with the guide surface 46e on the back surface of the top portion 46d. The operation portion 42 is fitted into the groove portion 50d. The length dimension of the guide rib 46 is a size corresponding to the sliding range of the driven portion 44, that is, an angle range in which the transmission shaft 32 rotates to transmit the rotation of the entire rotation angle range to the rotation shaft 24. The sliding range of the driven portion 44 for rotation is set.

  As shown in FIG. 4A, first, the guide rib 46 is fixed on the surface of the glass plate 12 with a double-sided tape or the like. At this time, only the guide rib 46 can be fixed on the surface of the glass plate 12 while the magnetic force that can be generated between the operation portion 42 and the driven portion 44 does not act, so that the guide rib 46 can be easily positioned and fixed. Can be done.

  Next, the operation portion 42 is positioned so that the case 50 of the operation portion 42 and the case 60 of the driven portion 44 face each other and the groove portion 50d of the operation portion 42 is positioned in parallel to the top portion 46d of the guide rib 46. .

  Next, as shown in FIG. 4B, the operation portion 42 is moved toward the glass plate 12 while maintaining the posture of FIG. 4A, and the locking portion 50 e of the operation portion 42 is moved to the top portion 46 d of the guide rib 46. Press. As a result, the groove portion 50 d of the operation portion 42 is elastically deformed, and the interval between the pair of locking portions 50 e is expanded by the top portion 46 d of the guide rib 46.

  When the locking portion 50e of the operation portion 42 is further pressed in the direction of the top portion 46d of the guide rib 46, the pair of locking portions 50e of the operation portion 42 get over the top portion 46d of the guide rib 46 as shown in FIG. Move to the surface 46e side. As a result, the guide rib 46 is fitted into the groove portion 50 d and the operation portion 42 is attached to the guide rib 46. The movement of the operation portion 42 in the direction away from the guide rib 46 is restricted because the locking portion 50 e of the operation portion 42 engages with the guide surface 46 e of the guide rib 46.

  Thus, since the operation part 42 is attached to the guide rib 46 after the guide rib 46 is fixed to the surface of the glass plate 12 in advance, the operation part 42 can be attached to an accurate position.

  Also, if the operating portion 42 is slid from the end portion into the guide rib 46 and fitted, the magnet 56 of the operating portion 42 and the magnet 66 of the driven portion 44 repel each other and the driven portion 44 escapes. There is a possibility that the case 50 of the operation unit 42 and the case 60 of the driven unit 44 cannot be mounted facing each other. In addition, the stoppers 46b and 46c of the guide rib 46 may become an obstacle. However, by attaching the operation portion 42 to the guide rib 46 from the front side of the surface of the glass plate 12, the operation portion 42 can be assembled while avoiding repulsion due to the action of the magnet 56 of the operation portion 42 and the magnet 66 of the driven portion 44. 46b and 46c do not get in the way.

  As shown in FIG. 3, the operation unit 42 assembled in this way is arranged so that the magnet 56 overlaps the magnet 66 of the driven unit 44, and the operation unit 42 is operated by the magnetic force generated between the magnets 56 and 66. 42 and the follower 44 are in a state of being adsorbed to each other. Therefore, the operation unit 42 is held at a predetermined height position without falling due to its own weight. Further, when the operation unit 42 is intentionally slid in the vertical direction, the driven unit 44 slides in the vertical direction integrally with the operation unit 42, and the transmission shaft 32 rotates. The operation unit 42 slides along the guide rib 46 in the vertical direction along the guide surface 46e, but further movement is restricted by the stoppers 46b and 46c at both the upper and lower ends of the guide rib 46.

  Thus, the engagement of the locking portion 50e of the operation portion 42 and the guide surface 46e of the guide rib 46 and the stoppers 46b and 46c at the upper and lower end portions of the guide rib prevent the operation portion 42 from falling off the guide rib 46.

Next, the operation of this embodiment will be described.
As shown in FIG. 5, when the operation unit 42 is at the intermediate position in the vertical direction of the guide rib 46, the slat 26 is in a horizontal state as shown in FIG. 7. Can be seen.

  From this state, when the operation part 42 is raised along the guide rib 46, the driven part 44 is raised integrally with the operation part 42, and the transmission shaft 32 is rotated. The rotation of the transmission shaft 32 is transmitted to the rotation shaft 24, the ladder tape 28 tilts, and the slat 26 rotates. Then, when the locking portion 50e of the operation portion 42 is raised to the position where it comes into contact with the stopper 46b at the upper end of the guide rib 46, that is, the position shown by the solid line in FIG. 6, the slat 26 rotates until it is in a substantially vertical fully closed state. . Thereby, the upper and lower ends of the slats 26 adjacent to each other in the vertical direction overlap each other, and the surface of the glass plate 12 is closed by the slats 26. As a result, as shown in FIG. 8, the person's silhouette 50 and the like cannot be seen through the slats 26, and the sunlight entering the room through the glass plate 12 and the line of sight of outside persons can be blocked.

  Further, when the operation unit 42 is lowered along the guide rib 46 from the position indicated by the solid line in FIG. 6, the driven unit 44 is lowered integrally with the operation unit 42, and the transmission shaft 32 rotates in the opposite direction to that when it is raised. . As a result, the rotating shaft 24 also rotates in the opposite direction to that when it is raised, and the ladder tape 28 is tilted in the direction opposite to that when it is raised. Then, when the operating portion 42 is moved down to the position indicated by the phantom line in FIG. 6, that is, the locking portion 50e of the operating portion 42 is brought into contact with the stopper 46c at the lower end of the guide rib 46, the slat 26 is inverted vertically by 180 degrees. Fully closed. As a result, the upper and lower ends of the slats 26 adjacent to each other overlap each other in the same manner as when ascending, and the surface of the glass plate 12 is closed by the slats 26. As shown in FIG. Can be cut off, and sunlight entering the room through the glass plate 12 and the line of sight of outsiders can be blocked. However, when the slat 26 has an arcuate cross-sectional shape, the direction of the convex surface of the vertical slat 26 is reversed in the front-rear direction when the operation unit 42 is raised and lowered.

  As described above, in the present invention, since the guide rib 46 is fitted into the groove 50d of the operation portion 42 and the movement of the operation portion 42 is guided by the guide rib 46, the operation device 40 can be reduced in size. Designability can also be improved.

  The groove portion 50d of the operation portion 42 may be provided over the entire vertical length of the fitting portion 50c. However, as shown in this example, the operation portion 42 is slid with respect to the guide rib 46 by being provided at a plurality of positions. The sliding resistance at the time can be reduced. Moreover, when attaching the operation part 42 to the guide rib 46, the elastic deformation of the groove part 50d including the latching | locking part 50e can be performed easily.

  In the above embodiment, a magnet is provided in each of the operation unit 42 and the driven unit 44 and the attractive force generated by each magnet is used. However, the present invention is not limited to this, and the operation unit 42 and the driven unit are used. Either one of the parts 44 may be a magnetic material instead of the magnet, or may be a combination of a magnet and a magnetic material.

  In the above embodiment, the rotation of the slat 26 is performed following the rotation of the rotating shaft 24. However, the present invention is not limited to this. May be performed.
