  By the way, in the technical example of Patent Document 1, two screw fixings are required for attaching the side cap, and the screws are inserted from the front and obliquely upward of the shutter case installed at a high place, so that the mounting workability is not good. . For example, it may take time to align the screw with the screw hole, or it may be necessary to fix the screw using a ladder for working at high places. In the technical example of Patent Document 2, the side cover can be attached with a single decorative screw, but the insertion direction is lateral, and the attachment workability is not good. In addition, the decorative screw and the surrounding side cover cap are always visible, and the design is deteriorated. Furthermore, in common with both technical examples, there is a possibility that the screw or the decorative screw may be accidentally dropped or lost during the side cap attaching operation.

  The present invention has been made in view of the above-described problems of the background art, and provides a shutter device that can easily and reliably perform the work of attaching and detaching the side cap to the side surface of the shutter case and has excellent design. Is a problem to be solved.

  Further, the shaft hole has a female screw on the inner periphery and is arranged in the vertical direction at the mounting position, and the shaft member has a male screw on the outer periphery of the shaft portion and is inserted into the shaft hole from below. It is preferable that the screw is engaged with a female screw and is moved by screwing in the axial direction.

  Furthermore, it is preferable that the shaft portion of the shaft member is always inserted without dropping from the shaft hole.

  Further, the receiving part and the restricting part are formed by a plate-shaped standby member that is bent with a slot that is wider than the outer diameter of the shaft part of the shaft member and narrower than the outer diameter of the head part. It is preferable that they are integrally formed.

  In the shutter device of the present invention, when the supported portion of the side cap is engaged with the support portion of the case main body, the side cap is suspended and supported and swings to the mounting position. At this time, if the shaft member is inserted into the shaft hole to such an extent that the shaft portion does not fall off in advance, the shaft member is received by the receiving portion. Thereafter, when the shaft member is moved in the axial direction, the restricting portion restricts the detachment of the shaft member, so that the attachment of the side cap is completed. In other words, the installation work performed by the operator is only required to perform the work of engaging the supported part with the support part and the work of moving the shaft member in the axial direction, and the side cap can be attached very easily and reliably. . If the reverse procedure is followed, the side cap can be removed very easily and reliably.

  In addition, since the shaft member, shaft hole, receiving portion, and restricting portion can be arranged on the side surface of the case body or the inner surface of the side cap and hidden by the side cap, the appearance of the shutter case can be improved and the design can be improved. Excellent. Further, since the shaft member can be inserted into the shaft hole in advance at a low place, the troublesome work of aligning the shaft member with the shaft hole at a high place is not required, and the attaching operation is further facilitated and ensured.

  Further, in the aspect in which the case main body has the side bracket, the side cap can be attached to and detached from the side bracket very easily and reliably.

  Furthermore, in a mode in which the shaft hole has a female screw and is arranged in the vertical direction, and the shaft member has a male screw and is inserted into the shaft hole from below, the shaft member is rotationally driven from below so that the mounting work is performed. The burden of working at height is reduced.

  Furthermore, in the aspect in which the shaft portion of the shaft member is always inserted into the shaft hole, there is no possibility that the shaft member is accidentally dropped or lost.

  Furthermore, in the aspect in which the receiving portion and the restricting portion are integrally formed by the standby member, the side cap can be reliably attached and detached even with a simple member configuration, and the manufacturing cost of the fixing portion can be reduced.

A slat 97 </ b> B at the upper end of the shutter curtain 96 is locked to the winding body 94. The individual slats 97 can be opened and closed and are provided with a blind function.

  The shutter case 92 includes a case body 2, a pair of left and right side caps 31 and 32, and a fixing portion 5 that fixes and attaches the side caps 31 and 32 to the side brackets 41 and 42 of the case body 2. After the case body 2 is installed at the installation location, the side caps 31 and 32 are attached to the side brackets 41 and 42. FIG. 2 is a perspective view showing the structure of the shutter case 92, and internal members such as the winding body 94 are not shown. In FIG. 2, the left side cap 31 is removed from the left side bracket 41, and the right side cap 32 is fixedly attached to the right side bracket 42 not visible in FIG.

  As shown in FIGS. 1 and 2, the case main body 2 includes a pair of left and right side brackets 41 and 42 and a case cover 21. The side brackets 41 and 42 are substantially plate-like members provided with a support portion for supporting the winding body 94, a mounting seat for fixing the electric drive device 99, a part of the fixing portion 5 described in detail later, and the like. . The side brackets 41 and 42 are formed by punching and bending the case plate using a press. The side brackets 41 and 42 are directly fixedly attached to a housing such as a wall surface on the back side of the sheet of FIG. 1 or indirectly fixedly attached via a base member. The left and right side brackets 41 and 42 are disposed above the left and right guide rails 91, respectively, and are spaced apart from each other and parallel to each other.

  The left and right side brackets 41 and 42 are symmetrical to each other, and will be described in detail below using the left side bracket 41 as an example. The upper edge of the side bracket 41 is bent toward the center of the shutter device 1 to form an upper edge flange 411 (shown in FIG. 2). Support portions 414 and 415 formed by rectangular holes are provided at two locations on the upper edge flange portion 411.

  The case cover 21 corresponds to the top plate and the front plate of the shutter case 92. The case cover 21 is formed by bending a rectangular thin plate wider than the width of the shutter curtain 96 from the horizontal direction to the vertical direction. Both edges in the width direction of the case cover 21 are attached from the upper edge to the front edge of the left and right side brackets 41 and 42. The case cover 21 and the pair of left and right side brackets 41 and 42 define the storage chamber 93 described above, and the shutter curtain 96 is held to be extendable.

  The winding body 94 is disposed in the accommodation chamber 93 and is supported by the left and right side brackets 41 and 42 so as to be rotatable around the axis AX. The winding body 94 can wind the shutter curtain 96 around the outer peripheral surface.

  The electric drive device 99 is disposed in a cylindrical internal space of the winding body 94, and one end on the left side in FIG. 1 is fixed to the side bracket 41. The electric drive device 99 has a drive motor 9A capable of switching between normal rotation and reverse rotation. A rotation transmission member 9B provided on the output shaft of the drive motor 9A rotates the inner periphery of the winding body 94. When the drive motor 9 </ b> A rotates in the forward direction, the winding body 94 is driven to rotate in the forward direction, and the shutter curtain 96 extends from the storage chamber 93. When the drive motor 9 </ b> A is reversed, the winding body 94 is driven to be reversed, and the shutter curtain 96 is wound up and accommodated in the accommodation chamber 93. Although omitted in FIGS. 1 and 2, the power supply line for supplying power to the electric drive device 99 and other control lines are routed using the space outside the side bracket 41.

  The pair of left and right side caps 31 and 32 are substantially rectangular lid members, and are attached to attachment positions outside the side brackets 41 and 42. The left and right side caps 31 and 32 are symmetrical to each other, and will be described in detail below using the left side cap 31 as an example. The upper edge, front edge, and rear edge of the side cap 31 are bent to form an upper edge flange 311, a front edge flange 312, and a rear edge flange 313 (see FIG. 2). The side cap 31 covers the side bracket 41 by having the flange portions 311, 312, and 313 on the three sides of the rectangle, and protects the end face of the electric drive device 99 and the wiring locations of the power supply line and the control line. Further, the side cap 31 also plays a role of improving the appearance of appearance.

  Claw-like supported portions 314 and 315 formed by bending downward are provided at two locations on the upper edge flange portion 311 of the side cap 31. 2, the supported portions 314 and 315 are engaged with the support portions 414 and 415 of the upper edge flange portion 411 of the side bracket 41. Accordingly, the side cap 31 is supported by being suspended from the side bracket 41 and swings to the attachment position.

  The fixing part 5 is a part for fixing the side cap 31 to the side bracket 41 as indicated by a broken line arrow R3 in FIG. The fixing portion 5 is disposed near the front side of the lower portions of the side cap 31 and the side bracket 41. The fixed portion 5 includes a shaft member 51, a shaft hole 52, and a standby member 53. Since the structure of the fixing part 5 is the same on both the left and right sides of the shutter case 92, the fixing part 5 on the left side in FIG. FIG. 3 is a perspective view showing the shaft hole 52 formed in the side cap 31. FIG. 4 is a perspective view showing the shaft member 51 inserted into the shaft hole 52 of the side cap 31. FIG. 5 is a perspective view showing the standby member 53 provided on the side bracket 41.

  As shown in FIG. 2, the shaft hole 52 is provided on the inner surface of the lower portion of the side cap 31 facing the front side bracket 41 and will be described in detail below. As shown in FIG. 3, the cylindrical member 523 is held at a location where two arm members 521 and 522 extending in a C shape from the inner surface of the side cap 31 are united. The cylindrical member 523 is held away from the inner surface of the side cap 31, and the axis AY extends in the vertical direction parallel to the inner surface. A shaft hole 52 is formed through the axial center of the cylindrical member 523 in the direction of the axis AY. The shaft hole 52 has a female screw (not shown) on the inner periphery.

  As shown in FIG. 4, the shaft member 51 is a screw member including a head 511 and a shaft portion 512. The shaft portion 512 has a male screw (not shown) on its outer periphery, and is screwed with the female screw of the shaft hole 52. The head portion 511 has a larger diameter than the shaft portion 512 and can be shaped to be rotated by a general plus driver or minus driver. Note that the rotational driving shape of the head 511 may be a hexagonal shape rotated by a spanner or other shapes. The shaft portion 512 of the shaft member 51 is inserted into the shaft hole 52 of the side cap 31 from below and screwed in the direction of the axis AY, so that the entire shaft member 51 moves upward.

  After the shaft member 51 is screwed into the shaft hole 52 and rises, a C-ring 513 is fitted around the shaft portion 512 that protrudes above the shaft hole 52 as shown in FIG. The C ring 513 rotates integrally with the shaft portion 512 and cannot enter the shaft hole 52. The fitting operation of the C-ring 513 can be performed in advance at the manufacturing plant, not at the installation location. Further, even when the fitting operation of the C ring 513 is performed at the installation location, it can be performed at a low location in advance. The fitting position of the C-ring 513 is appropriately set based on the height relationship with the standby member 53 described later. With the C ring 513, the shaft portion 512 of the shaft member 51 is always in an inserted state without dropping from the shaft hole 52. FIG. 3 illustrates a state in which the shaft portion 512 is screwed back to the limit of the shaft hole 52 and the C ring 513 is in contact with the upper surface of the cylindrical member 523. The shaft member 51 does not descend any further.

  As shown in FIG. 2, the standby member 53 is provided toward the side cap 41 toward the front side of the lower end of the side bracket 41 and will be described in detail below. As shown in FIG. 5, the standby member 53 has a plate shape and includes a horizontal portion 531 extending from the lower end of the side bracket 41 and a vertical portion 532 bent downward from the middle. Further, a slot 533 having a groove width A is formed from the horizontal portion 531 to the vertical portion 532. The groove width A is wider than the outer diameter of the shaft portion 512 of the shaft member 51 and narrower than the outer diameter of the head portion 511.

  The slot 533 of the waiting member 53 corresponds to a receiving portion of the present invention that receives the shaft member 51 inserted into the shaft hole 52 from the side surface direction perpendicular to the axis AY direction. The vertical portion 532 of the standby member 53 corresponds to a restricting portion that restricts the detachment of the head portion 511 of the shaft member 51 that has been received in the receiving portion and moved in the axis AY direction of the shaft hole 52.

  Next, a method for attaching the side cap 31 in the shutter device 1 of the embodiment configured as described above will be described. FIG. 6 is an enlarged front view of the fixed portion 5 showing a state in which the supported portions 314 and 315 of the side cap 31 are supported by the support portions 414 and 415 of the side bracket 41 and the side cap 31 swings toward the mounting position. FIG. FIG. 7 is an enlarged front view of the fixing portion 5 showing a state in which the side cap 31 swings to the attachment position. FIG. 8 is an enlarged front view of the fixing portion 5 showing a state in which the attachment of the side cap 31 is finished.

  The operator first looks at the side cap 31 and confirms that the shaft member 51 is screwed down from the shaft hole 52 and is lowered. Next, the operator engages the supported portions 314 and 315 of the side cap 31 with the support portions 414 and 415 of the side bracket 41 and suspends the side cap 31. Then, as indicated by a broken line arrow R4 in FIG. 6, the side cap 31 automatically swings due to its own weight and reaches the attachment position shown in FIG. At this time, since the shaft member 51 is sufficiently lowered, the head portion 511 passes under the vertical portion 532 of the standby member 53, and the shaft portion 512 passes through the slot 533.

  If the shaft member 51 is not lowered sufficiently, the head portion 511 comes into contact with the vertical portion 532 of the standby member 53 and the side cap 31 cannot reach the attachment position. In this case, the operator may rotate the head 511 of the shaft member 51 in the screwing direction by work from below to sufficiently lower the shaft member 51.

  In the situation of FIG. 7, the worker rotates the head 511 of the shaft member 51 in the screwing direction by work from below. Then, the shaft member 51 rises in the shaft hole 52 as shown by a broken line arrow R5 in FIG. In FIG. 8, the head portion 511 of the shaft member 51 abuts or approaches the lower surface of the horizontal portion 531 of the waiting member 53, and becomes substantially the same height as the vertical portion 532. Since the groove width A of the slot 533 of the vertical portion 532 is narrower than the outer diameter of the head portion 511, the vertical portion 532 restricts the separation of the head portion 511. Thereby, the attachment of the side cap 31 is completed.

  Further, when removing the side cap 31 for maintenance or the like, a procedure reverse to the attachment may be performed. That is, in the attached state of FIG. 8, the worker first rotates the head 511 of the shaft member 51 in the screwing direction by working from below, so that the head 511 of the shaft member 51 is perpendicular to the standby member 53. Lower than part 532. As a result, the shaft member 51 can pass through the slot 533. Next, the operator lifts the side cap 31 while swinging, removes the supported portions 314 and 315 from the support portions 414 and 415, and the removal operation is completed.

  According to the shutter device 1 of the embodiment, the attachment work performed by the worker includes the work of engaging the supported parts 314 and 315 with the support parts 414 and 415, and the axis member AY by rotationally driving the shaft member 51 at the attachment position. It only takes two tasks to move in the direction. Therefore, the work of attaching the side cap 31 to the side bracket 41 can be performed very easily and reliably. Moreover, if the reverse procedure is followed, the removal work of the side cap 31 can be performed very easily and reliably.

  Further, the operation of inserting the shaft member 51 into the shaft hole 52 and fitting the C-ring 513 into the shaft portion 512 can be performed in advance at the manufacturing factory, or can be performed at a low place at the installation location. Therefore, the troublesome work of aligning the shaft member 51 with the shaft hole 52 at a high place becomes unnecessary, and the attaching work becomes even easier and more reliable. Further, the shaft portion 512 of the shaft member 51 is inserted into the shaft hole 52 and is prevented from dropping by the C ring 513. Therefore, the operator has no fear of dropping or losing the shaft member 51 by mistake. Further, since the worker performs the mounting work by rotating the shaft member 51 from below, the burden on the high place work is reduced.

  In addition, since the shaft member 51, the shaft hole 52, and the standby member 53 are hidden by the side cap 31, they are not visible from the outside. Therefore, the appearance of the shutter case 92 can be improved and the design is excellent. Further, the receiving member and the restricting portion can be integrally formed by the standby member 53. Therefore, even if it is a simple member structure, the side cap 31 can be attached or detached reliably, and the manufacturing cost of the fixing | fixed part 5 can be reduced.

  Contrary to the embodiment, even when the standby member 53 is provided in the side cap 31 and the shaft hole 52 and the shaft member 51 are provided in the side bracket 41, the same operation and effect are produced. Moreover, the structure of the fixing | fixed part 5 of this invention is not limited to the fixing method of the side cap 31, For example, it can apply also to the fixing method of the lower edge of the case cover 21. FIG. Various other applications and modifications are possible for the present invention.
