This end is connected to the main body 20A of the anti-vibration means 20 by fitting the loop formed on the other end of the string-like member 31 to the pin member 20C erected on the projecting portion 20B. It is Unlike the door 1, the main body 20A of the anti-vibration means 20 does not move to open or close and is immovable.

As shown in FIG. 7, the body 20A of the anti-vibration means 20 is hit by the body 17A of the upper hanging means 17 provided on the door 1 when the door 1 moves to close. When the door stop member 20D is attached and the main body 17A contacts the door stop member 20D, the door body 1 reaches the fully open position.

As shown in FIG. 10, inside the take-up reel 38, there is provided a space in which the above-mentioned spiral spring 40, which is a spiral spring, is accommodated. An outer end portion 40A of the spiral spring 40 is connected to the take-up reel 38 by a connector 41, and an inner end portion 40B is inserted into an elongated hole 35B formed in the central shaft 35, thereby It is connected to shaft 35 . Therefore, as described above, when the door 1 is moved open from the fully closed position, the string-like member 31 is let out from the driving device 30 while the take-up reel 38 is rotated. Due to the rotation of the take-up reel 38, a return spring force is accumulated in the spiral spring 40. The return spring force thus accumulated causes the take-up reel 38 to wind up the cord-like member 31, thereby causing the door 1 to move. Automatically close and move.

When the operator rotates the rotary operation member 36 by hand while the door 1 is stopped at the fully open position or the like, and rotates the central shaft 35 by this rotation operation, the swirl occurs in accordance with the rotation direction. Since the spring 40 is wound tightly or unwound, the initial spring force of the spiral spring 40 can be adjusted. It can be adjusted to an appropriate value according to the movement speed or the like.

Further, as shown in FIGS. 8 and 10, in the drive device 30 of the present embodiment, when the two rotary operation members 36 provided in the drive device 30 are rotated, the center shaft 35 is provided with a moderate rotation means 43 for allowing it to rotate moderately by a constant angle. The detent rotating means 43 is composed of a polygonal portion 44 provided on the central shaft 35 inside the case 37 and a spring member 45 elastically contacting the outer surface of the polygonal portion 44 . Since the polygonal portion 44 of this embodiment is formed by a hexagonal nut that is screwed or otherwise fixed to the outer periphery of the central shaft 35, the polygonal portion 44 is connected to the rotation operation member 36. As shown in FIGS. 11 and 12, which are schematic front views showing the relationship with the moderate rotation means 43, a hexagonal projection 44A is provided with six projections 44A in the circumferential direction of the central shaft 35 at equal intervals of 60 degrees. Department. 8, 11 and 12, the spring member 45 is in elastic contact with the two parallel outer surfaces of the polygonal portion 44, so that these outer surfaces are This spring member 45 is made of a U-shaped or substantially U-shaped plate spring that elastically clamps, and this spring member 45 is secured via a connecting member 48 by a stop member 47 that is secured to the inner surface of the case 37 by a fastener 46 . is stopped by the case 37.

Therefore, when the central shaft 35 is rotated by the rotary operation member 36, as shown in FIG. 11 and FIG. The member 45 climbs over the protrusion 44A provided on the polygonal portion 44 at an equal angle of 60 degrees around the central axis 35 by the elastic opening of the spring member 45. Since the center shaft 35 is elastically contacted with the following two parallel outer surfaces, the rotation of the central shaft 35 by the rotation operating member 36 is performed as moderate rotation by a constant angle of 60 degrees. When the spring member 45 is in elastic contact with two parallel outer surfaces of the polygonal portion 44 , the rotation of the rotary operation member 36 and the central shaft 35 is caused by the elastic clamping force of the spring member 45 . will stop.

As shown in FIG. 6, each of the two rotary operation members 36 rotated to rotate the central shaft 35 has a thickness direction corresponding to the thickness direction of the door body 1. As shown in FIG. 8, on the outer periphery of these rotary operation members 36, there are projections 36A projecting radially outward and recesses recessed radially inward. Six portions 36B are provided alternately in the circumferential direction about the central axis 35, and therefore the front shape of the rotary operation member 36 is star-shaped or substantially star-shaped. Since the six projections 36A are provided at equal intervals in the circumferential direction of the rotary operation member 36 centering on the central axis 35, these projections 36A are rotated 60 degrees around the central axis 35. This 60-degree angle is the same as the 60-degree equal angle around the central axis 35 for the six protrusions 44A of the polygonal portion 44 described above.

It should be noted that, as shown in FIG. 8, each recessed portion 36B formed in the outer peripheral portion of each rotary operation member 36 so as to be recessed toward the central axis 35 is a rotary operation member that rotates about the central axis 35 as shown in FIG. These recesses 36B, like the protrusions 36A, are also located 60° from the center axis 35, because they are provided in the central position between the two protrusions 36A that are adjacent to each other in the circumferential direction of the protrusions 36A. are provided at equal angles.

The positions of the projections 44A of the polygonal portion 44 and the positions of the projections 36A of the respective rotary operation members 36 are at the same angular positions in the circumferential direction about the central axis 35, so that these rotary operations are performed. The member 36 is attached to the extension end portion 35A of the central shaft 35 described above.

Also, as shown in FIGS. 8 and 11, when the rotation of the central shaft 35 is stopped by the moderate rotating means 43, six rotating operating members 36 are provided on the outer peripheral portion of each rotating operating member 36. The positions of the polygonal portion 44 and the rotary operation member 36 in the rotational direction with respect to the central axis 35 so that one of the concave portions 36B is located directly above or substantially above the central axis 35. is set.

Further, as shown in FIG. 6, when the driving device 30 is housed inside the door 1, two rotary shafts provided on both sides of the door 1 in the thickness direction of the driving device 30 are provided. Most of the operation members 36 except for the upper portion are housed inside the door 1 , and these rotary operation members 36 are arranged within the thickness of the door 1 . The work for housing and arranging the driving device 30 and the rotary operation member 36 inside the door 1 in this way consists of the central shaft 35 and the two rotary operation members 36 as shown in FIG. 7 and 8 show the state of the driving device 30 at this time. Of the six recessed portions 36B, one recessed portion 36B reaches directly above or substantially directly above the central axis 35, so that the two protrusions on both sides of this one recessed portion 36B are in contact with each other. A portion 36A protrudes upward from the base portion 19A of the above-described upper guide member 19 disposed on the upper portion of the door 1, as shown in FIG.

As shown in FIG. 6, the base portion 19A, together with a pair of rising portions 19B and 19C provided on the upper guide member 19 apart in the thickness direction of the door member 1, is positioned on the upper outer edge of the door member 1. Therefore, the two protrusions 36A of each rotary operation member 36 are arranged upward from the bottom formed by the base portion 19A of the recess 39. It protrudes to The projection dimension of these protrusions 36A from the bottom of the recess 39 is smaller than the depth dimension of the recess 39. As shown in FIG.

By rotating the center shaft 35 from the state shown in FIGS. 8 and 11 by the rotation operation member 36, the rotation angle of the center shaft 35 is adjusted so that the spring member 45 is a polygonal portion as shown in FIG. 44, one protrusion 36A out of the six protrusions 36A reaches a position directly above or substantially above the central axis 35. At this time, this one protrusion 36A protrudes upward from the bottom of the recess 39, and the protrusion dimension of this protrusion 36A from the bottom of the recess 39 is also smaller than the depth dimension of the recess 39. .

For this reason, in the present embodiment, the intervals in the circumferential direction about the central axis 35 of the six protrusions 36A provided on each rotary operation member 36 are irrespective of the rotation angle of the central axis 35. That is, regardless of the rotation angle of the rotary operation member 36, at least one projection 36A projects upward from the bottom of the recess 39. As shown in FIG.

The six projections 36A provided on each of the rotary operation members 36 serve as operating portions that can be operated by the operator's hand from the outside of the door 1 to rotate the rotary operation member 36. By rotating the rotary operation member 36 and rotating the central shaft 35 by these operation portions, the work for adjusting the initial spring force of the spiral spring 40 of the driving device 30 can be carried out. .

As shown in FIG. 3, this work is performed by moving the door 1 to open and stopping it at the fully open position. As a result, most of the upper portion of the door 1 reaches a position separated from the blind member 4 described above, and the driving device 30 arranged inside the door 1 and the center shaft 35 of the driving device 30 The rotary operation member 36 attached to the extended end portion 35A is arranged near the edge of the upper outer edge of the door 1 on the door bottom side. Since the spiral spring 40 reaches a position where it is not covered by the mesh member 4, the rotation operation member 36 is rotated by the protrusion 36A, which is the operation portion described above, to rotate the central shaft 35. can be easily performed without being affected by the blind member 4.

As shown in FIG. 6, the upper outer edge of the door 1 of the present embodiment is provided with a rising portion 16B of the upper frame member 16 on the side where the operator works. Of the two rotating operation members 36 provided on both sides in the thickness direction of the door 1 in the driving device 30, the operator rotates the rotating operation member 36 arranged on the side opposite to the rising portion 16B. As a result, the spring force adjusting work for the initial value of the spiral spring 40 can be performed.

Further, in the present embodiment, the operation portion operated to rotate the rotary operation member 36 is a projection projecting upward from the bottom of the recess 39 provided in the upper outer edge of the door 1 as described above. 36A, and since the projection dimension of this projection 36A from the bottom of the recess 39 is smaller than the depth dimension of the recess 39, the projection 36A can reach any position in the opening/closing movement direction of the door body 1. It is possible to prevent an unexpected external force or the like from acting on the

Also, the intervals in the circumferential direction around the central axis 35 of the six protrusions 36A provided on the outer peripheral portion of the rotary operation member 36 depend on the rotation angle of the rotary operation member 36, as described above. Regardless, since at least one protrusion 36A protrudes upward from the bottom of the recess 39, the rotation operation of the rotation operation member 36 by the protrusion 36A can be performed by any rotation angle of the rotation operation member 36. It can be implemented even if

Furthermore, the driving device 30 according to the present embodiment is provided with a moderate rotation means 43 for allowing the central shaft 35 to rotate in a constant angle of 60 degrees in a moderate manner by rotating the rotation operation member 36. The angle of 60 degrees is the same angle as the six projections 36A provided at equal angles of 60 degrees on the rotary operation member 36, so that the rotary operation member 36 can be rotated. The operator can clearly feel the rotation angle and number of rotations of the rotation operation member 36 and the central shaft 35 and perform this rotation operation.

Further, as described above, the position of the projection 44A of the polygonal portion 44 provided on the central shaft 35 and the position of the projection 36A of the rotary operation member 36 are different in the circumferential direction around the central shaft 35. Since they are in the same angular position, the operator who performs the operation of rotating the rotary operation member 36 can rotate the central shaft 35 via the rotary operation member 36 by the moderate rotation means 43 in a more tangible and moderate manner. This rotation operation work can be performed while feeling it as a rotation.

Further, on the outer peripheral portion of the rotary operation member 36, between the respective protrusions 36A, there are provided recesses 36B that are recessed on the inner diameter side, that is, toward the central shaft 35 side. Of the portions 36B, one recessed portion 36B is positioned directly above or substantially directly above the central shaft 35 when the rotation of the central shaft 35 and the rotary operation member 36 is stopped by the moderate rotating means 43, as described above. has reached the upper position. When the rotation of the central shaft 35 and the rotary operating member 36 is stopped by the detent rotating means 43 in this manner, the work for adjusting the spring force of the initial value of the spiral spring 40 is completed. Upon completion of this work, the opening and closing movement of the door 1 is performed. When the door 1 is fully closed, the door 1 is positioned as shown in FIG. Anti-vibration means 20 having an anti-vibration member 21 for preventing vibration in the thickness direction of the center axis 35, and the above-mentioned one recessed portion 36B reaching a position directly above or substantially above the central axis 35 The positional relationship between the anti-vibration means 20 and the anti-vibration means 20 is such that the recessed portion 36B reaches a position directly below or substantially directly below the anti-vibration means 20. It is possible to eliminate the interference of the rotary operation member 36 with

In other words, when the rotary operation member 36 is a circular rotary operation member 36' around the central axis 35 as indicated by the two-dot chain line in FIG. When closed, the circular rotary operation member 36' interferes with the anti-vibration means 20 or there is a risk of interference, but the rotation of the central shaft 35 and the rotary operation member 36 is stopped by the moderate rotation means 43. Since the position of one recessed portion 36B reaching a position directly above or substantially directly above the central axis 35 is positioned directly below or substantially directly below the anti-vibration means 20, The occurrence of such interference can be eliminated.

In the driving device 30 of the present embodiment, the axial direction of the central shaft 35 is the thickness direction of the door 1 as described above, and both ends of the central shaft 35 in the axial direction are located in FIGS. 10, there are extended ends 35A that extend outside the case 37 of the drive device 30, and each of these extended ends 35A has the same shape and is synchronous. Since the rotary operation member 36 that rotates is attached, the driving device 30 is provided with two rotary operation members 36 on both sides in the thickness direction of the door 1 . According to this, as described above, even if the rising portion 16B of the upper frame member 16 is provided at the upper outer edge portion of the door 1 on the side where the operator works in the thickness direction of the door 1 By operating the rotary operation member 36 on the side opposite to the rising portion 16B of the two rotary operation members 36, the spring force adjustment work of the initial value of the spiral spring can be easily performed. As for the sliding door device of this embodiment shown, for a sliding door device with opposite sides in which the opening movement direction and the closing movement direction of the door body are opposite, it is possible to selectively use the rotating operation member for rotating operation. As a result, the driving device 30 including the rotating operation member 36 can be shared for the left and right sliding door devices.
