The door hanger 28 is provided with a door wheel 28a, and the door wheel 28a rolls on a linear rail 29 described later. When the belt member 26 travels so as to go around, the door 18 moves linearly in the width direction of the opening 12 along the linear rail 29 so as to open and close the opening 12.

  The exterior body 21 includes a fixed side member 32, a cover member 33, and fixing means 34 (see FIG. 7) for fixing the cover member 33 to the fixed side member 32. The fixed side member 32 is configured to be fixed to the wall 11 of the building, and is fixed to the front side surface of the frame member 13. A space having a rectangular cross section in the direction perpendicular to the moving direction of the door body 18 is formed in the exterior body 21 by the fixed side member 32 and the cover member 33.

  The fixed side member 32 includes a superposed portion 35 that is superimposed on the front side surface of the frame member 13, and a top portion 36 that protrudes horizontally from the top surface of the superposed portion 35. The stationary member 32 constitutes the back wall and the upper surface portion of the exterior body 21. The overlapping portion 35 has a vertical width smaller than the found width of the frame material 13, and the outer surface of the overlapping portion 35 is formed in a flat shape. The top portion 36 projects from the overlapping portion 35 toward the front side (the side away from the frame material 13 to which the exterior body 21 is attached). The outer surface (upper surface) of the top part 36 is formed horizontally. Therefore, the overlapping portion 35 is located on the back side in the exterior body 21.

  The overlapping portion 35 is formed with an insertion hole 35a through which a screw 38 for fixing the frame material 13 is inserted. A linear rail 29 is formed integrally with the overlapping portion 35. The linear rail 29 is formed so as to protrude from the inner surface of the overlapping portion 35, and is formed over the entire length direction of the overlapping portion 35 (the width direction of the opening 12 and the moving direction of the door 18). Yes.

  The stationary member 32 is integrally formed with a groove portion 40, a support portion 41, a locking portion 42, and a receiving portion 43. The groove portion 40, the support portion 41, the locking portion 42, and the receiving portion 43 are formed over the entire length direction of the fixed side member 32 (the width direction of the opening 12 and the movement direction of the door body 18).

  The groove part 40 is comprised by the dovetail groove, and has a pair of drooping parts 40a and 40b which protruded below from the inner surface of the top part 36, and the bottom part 40c which connects the lower ends of this pair of drooping parts 40a and 40b. . The pair of drooping portions 40 a and 40 b are arranged at a distance from each other in a direction orthogonal to the length direction of the fixed side member 32. The gap between the hanging portions 40a and 40b can be inserted through the head of a fastener such as a bolt 52a. An opening 40d extending along the moving direction of the door body 18 is formed in the bottom portion 40c. A screw portion of a bolt 52a having a head inserted between the hanging portions 40a and 40b is inserted into the opening 40d.

  The support portion 41 includes a support portion main body 41a protruding downward from an end portion of the top portion 36 (an end portion opposite to the overlapping portion 35), and a lateral side from the lower end portion of the support portion main body 41a toward the groove portion 40 side. And a mounting portion 41b that protrudes into the body. The placement portion 41 b is located below the bottom portion 40 c of the groove portion 40. The support portion 41 is provided at a distance from one drooping portion 40b (the drooping portion 40b located on the side opposite to the overlapping portion 35; the drooping portion 40b on the side away from the frame member 13).

  The locking portion 42 includes a locking portion main body 42a protruding from the support portion main body 41a toward the front side (a side away from the frame material 13 to which the exterior body 21 is attached), and a lower side from the end of the locking portion main body 42a. It has a claw portion 42b projecting toward it and is formed in a bent shape.

  The receiving portion 43 protrudes from the support portion main body 41 a toward the front side at a position below the locking portion 42. The protrusion width of the receiving portion 43 from the support portion main body 41a is larger than the protrusion width of the locking portion 42 from the support portion main body 41a. The end surface of the receiving portion 43 functions as a receiving surface 44 with which the cover member 33 abuts.

  The cover member 33 has a vertical portion 46 and a horizontal portion 47 extending in the horizontal direction from the lower end portion of the vertical portion 46, and is formed in an L-shaped cross section. The cover member 33 constitutes a front wall and a lower surface portion of the exterior body 21. Although not shown in the drawings, side covers that cover the end portions of the exterior body 21 in the longitudinal direction are respectively attached to both end portions of the cover member 33 in the longitudinal direction.

  A locked portion 48 is formed integrally with the vertical portion 46 of the cover member 33. The locked portion 48 protrudes laterally from the inner surface of the vertical portion 46 toward the back side and is bent substantially vertically upward from the end portion thereof, and the locked portion main body 48a. Claw part 48b formed at the upper end of 48a. The vertical width of the locked portion 48 is formed to be slightly larger than the gap width between the claw portion 42 b of the locking portion 42 and the receiving portion 43. Therefore, in order to attach the cover member 33 to the fixed side member 32, the cover member 33 is rotated from the posture in which the lateral portion 47 (locked portion main body 48a) faces downward to the posture in which the lateral portion 47 faces horizontal. It is necessary to install it. Therefore, the cover member 33 cannot be removed from the fixed member 32 simply by moving the cover member 33 in the horizontal direction.

  As shown in FIGS. 2A to 4, some components of the drive mechanism 20 are fixed to the stationary member 32 by a plate member 51. The plate member 51 is connected to a rectangular flat plate-shaped fixed plate portion 51a in which an insertion hole 51c for inserting a bolt 52a is formed, and a mounting portion 51b that is bent vertically from the fixed plate portion 51a and hangs down from the fixed plate portion 51a. And have. Note that an insertion hole through which the bolt is inserted is also formed in the attachment portion 51b.

  As shown in FIG. 2B, the motor 23 which is a component of the drive mechanism 20 is attached to the fixed member 32 by plate members 51 provided on both sides in the length direction. The plate member 51 is fixed to the fixed side member 32 by fasteners (bolts 52a and nuts 52b). Specifically, as shown in FIG. 3, the bolt 52 a inserted through the insertion hole 51 c of the fixed plate portion 51 a of the plate member 51 is inserted into the gap between the hanging portions 40 a and 40 b of the groove portion 40. At the same time, the screw part is arranged in a posture extending downward from the head. The head of the bolt is formed in a rectangular shape, for example, so that it does not rotate when the nut 52b is screwed into the threaded portion of the bolt 52a. And the screw part is penetrated by the insertion hole 51c of the fixed board part 51a. In this state, the fixing plate portion 51a is sandwiched between the nut 52b located below the fixing plate portion 51a and the bottom portion 40c of the groove portion 40, and the nut 52b is screwed into the screw portion.

  As shown in FIG. 2A, the attachment members 53 of the driven pulley 25, which is a component of the drive mechanism 20, are attached to the stationary member 32 by plate members 51 provided on both sides in the length direction. As shown in FIG. 4, the configuration of the plate member 51 that fixes the attachment member 53 of the driven pulley 25 to the fixed side member 32 is the same as the configuration of the plate member 51 that fixes the motor 23 to the fixed side member 32.

  As shown in FIGS. 3 and 4, the fixing plate portion 51 a has an end portion on the overlapping portion 35 side (frame material 13 side) fixed to the groove portion 40, while the other end portion is a mounting portion 41 b of the support portion 41. Is placed. The fixed plate portion 51a is in a horizontal posture in this state. That is, the mounting portion 41b is positioned below the bottom portion 40c of the groove portion 40 by an amount corresponding to the thickness of the fixed plate portion 51a. Thereby, the fixed plate part 51a is horizontal. By adopting a configuration in which the end portion of the fixed plate portion 51a is placed on the placement portion 41b, the operator needs to hold the plate member 51 when the nut 52b is screwed into the screw portion of the bolt 52a. Disappears. Therefore, the work load can be reduced.

  The end portion of the fixed plate portion 51 a is in contact with the side surface of the support portion 41. That is, in FIG.3 and FIG.4, the edge part of the fixing plate part 51a is contact | abutted to the support part 41 from the left side, and the position of the left-right direction of the fixing plate part 51a is determined by this. Since the left-right direction coincides with the direction in which the drive shaft of the motor 23 extends and the width direction of the belt member 26, the position of the motor 23 and the attachment member 53 of the driven pulley 25 in the direction in which the drive shaft extends (width direction of the belt member 26). Is fixed at a predetermined position by the fixed plate portion 51a (plate member 51). In addition, the motor 23 is arranged in such a posture that the drive shaft to which the drive pulley 24 is attached projects from the main body of the motor 23 toward the linear rail 29 side. Therefore, it is possible to prevent the relative positional relationship between the belt member 26 positioned at a predetermined position with respect to the linear rail 29 and the driving pulley 24 and the driven pulley 25 from shifting in the left-right direction in FIGS. 3 and 4. it can.

  As shown in FIGS. 3 and 4, the automatic door device 10 is provided with pressing means 55 that presses the fixed plate portion 51a against the placement portion 41b. The pressing means 55 includes a male screw member 55a that is screwed into the screw hole 51d of the fixed plate portion 51a, and a nut 55b that is screwed into the male screw member 55a. The male screw member 55a is screwed into the screw hole 51d of the fixed plate portion 51a, and the distal end portion of the male screw member 55a is in contact with the inner surface of the top portion 36. By rotating the male screw member 55a in this state, the upward protrusion amount of the male screw member 55a from the fixed plate portion 51a gradually increases. As a reaction, the fixed plate portion 51a is pressed against the placement portion 41b. The nut 55b is used to prevent the male screw member 55a from rotating and to maintain a pressing force on the mounting portion 41b. The nut 55b can be omitted.

  Since the fixed plate portion 51a is placed on the placement portion 41b, a part of the weight of the fixed plate portion 51a rests on the placement portion 41b. In the present embodiment, in addition to its own weight, a pressing force by the pressing means 55 is applied to the mounting portion 41b. For this reason, even if the length dimension of the fixed plate portion 51a (the length dimension in the moving direction of the door body 18) is reduced, the mounting member 53 of the motor 23 and the driven pulley 25 is fixed by the fixed plate portion 51a (plate member 51). It is fixed stably.

  As shown in FIG. 5, an attachment member 57 of the controller 56 can be fixed to the groove portion 40. The controller 56 controls the opening / closing drive of the door body 18 by the drive mechanism 20. The attachment member 57 of the controller 56 has a flat plate-like fixing portion 57a in which an insertion hole is formed, and an attachment portion 57b that hangs down from an end portion of the fixing portion 57a. The attachment member 57 is fixed to the groove part 40 by inserting the bolt 52a attached to the groove part 40 through the insertion hole of the fixing part 57a and screwing the nut 52b. The controller 56 is attached to the attachment portion 57b.

  As shown in FIGS. 3 to 5, the drive mechanism 20 and the controller 56 are arranged on the front side (the side far from the wall body 11 and the frame material 13) with respect to the movement region of the door body 18. Since the motor 23, the driving pulley 24, the driven pulley 25, the belt member 26, and the controller 56 are on the front side of the door body 18 and the door hanger 28, when performing the maintenance work by removing the cover member 33 from the fixed side member 32, The door 18 and the door hanger 28 do not interfere with the work.

  As shown in FIG. 6, an activation sensor 59 can be attached to the exterior body 21. The activation sensor 59 is, for example, an infrared activation sensor, and can be fixed to the cover member 33 so that the detection portion 59a is exposed from an opening formed in the lateral portion 47 of the cover member 33.

  As shown in FIG. 7, the fixing means 34 for fixing the cover member 33 to the fixed side member 32 includes a fixing member 61 whose one end (upper end) is fastened to the fixed side member 32, other than the fixing member 61. And a screw 62 as a fixture for fastening the end (lower end) to the cover member 33. One end of the fixing member 61 is fixed to the groove 40 by fasteners 63a and 63b. Specifically, one end portion of the fixing member 61 extends horizontally along the bottom portion 40c of the groove portion 40, and has a horizontal portion 61a formed with an insertion hole through which the screw portion of the bolt 63a is inserted. And a vertical portion 61b extending upward along the hanging portion 40b. A bolt 63a is attached to the groove portion 40, and a horizontal portion 61a of the fixing member 61 is sandwiched between a nut 63b and a bottom portion 40c that are screwed into a screw portion of the bolt 63a. With this configuration, one end of the fixing member 61 is fixed to the groove 40. A gap is formed between one drooping portion 40 b adjacent to the vertical portion 46 and the vertical portion 46.

  The fixing member 61 extends downward from one end portion, and is bent in the horizontal direction at the other end portion (lower end portion) of the fixing member 61. A fastening hole 61 c for fastening the screw 62 is formed at the other end of the fixing member 61. The screw 62 is inserted into a screw hole (insertion hole) 47 b of a recess 47 a formed in the lateral portion 47 of the cover member 33. The screw 62 is arranged so that the screw 62 is not conspicuous from the outside by arranging the head in the recess 47a.

  Here, a method of attaching the cover member 33 to the fixed side member 32 will be described.

  In order to attach the cover member 33 to the fixed side member 32, the locked portion 48 is locked to the locking portion 42 in a state where the cover member 33 is inclined so that the lateral portion 47 (locked portion main body 48 a) faces downward. It is inserted into the gap between the claw part 42 b and the receiving part 43. Then, the claw portion 48 b of the locked portion 48 is engaged with the claw portion 42 b of the locking portion 42. When the cover member 33 is rotated in the direction in which the tip of the lateral portion 47 rises in a state where the claw portion 48 b of the locked portion 48 is engaged with the claw portion 42 b of the locking portion 42, the vertical portion 46 of the cover member 33. Of the fixed side member 32 comes into contact with the tip end surface (receiving surface 44) of the receiving portion 43. When the vertical portion 46 comes into contact with the receiving surface 43, as schematically shown in FIG. 8A, the cover member 33 is in a state before the horizontal portion 47 becomes horizontal. That is, if the vertical portion 46 is in a natural state when the cover member 33 is in contact with the tip surface (receiving surface 44) of the receiving portion 43, the vertical portion 46 is slightly inclined. At this time, the screw hole 47 b of the lateral portion 47 is slightly displaced to the front side (side away from the linear rail 29) with respect to the fastening hole 61 c of the fixing member 61. Then, the vertical portion 46 is elastically bent by applying a force to the vertical portion 46 so that the lower end portion of the vertical portion 46 moves toward the linear rail 29, thereby fastening the screw hole 47 b of the horizontal portion 47 to the fixing member 61. The screw 62 is fastened in this state according to the hole 61c (see FIG. 8B). Therefore, the receiving surface 44 is pressed from the cover member 33 when the cover member 33 is fixed to the fixed side member 32 by the fixing means 34. In other words, the cover member 33 is maintained in an elastically deformed state by fastening the cover member 33 to the lower end portion of the fixing member 61 with the screws 62. Accordingly, the screw 62 causes the cover member 33 to generate a force that presses the receiving surface 44 of the stationary member 32. The screws 62 fix the cover member 33 to the fixed side member 32 so that a force that the cover member 33 presses the receiving surface 44 is generated. At this time, the locked portion 48 is locked to the locking portion 42 of the fixed side member 32.

  As shown in FIG. 9, a wiring pressing member 65 for holding wiring such as signal lines and power supply lines can be fixed to the fixed side member 32. As shown in FIG. 10, the wiring pressing member 65 is an integrally molded product made of resin, and includes a wiring insertion part 66, a flat plate part 67, and a preliminary insertion part 68. The wiring insertion part 66 forms a space through which wiring passes between the top part 36 and the wiring part 66. The flat plate portion 67 is formed integrally with the wiring insertion portion 66, and a pair of claw portions 67a for engaging with the groove portion 40 are provided upright. The preliminary insertion portion 68 is a part for forming a preliminary space. The flat plate portion 67 is disposed along the bottom portion 40 c when the wiring pressing member 65 is mounted in the groove portion 40.

  The pair of claw portions 67a includes a base portion 67b erected from the flat plate portion 67, and an overhanging portion 67c that protrudes away from the end portion of the base portion 67b. The distance between the outer surfaces of both bases 67b is slightly larger than the width of the opening 40d of the groove 40. On the other hand, the width of the base portion 67 b is smaller than the width of the opening 40 d of the groove portion 40. For this reason, when the claw portion 67a is attached to the groove portion 40, the claw portion 67a is inserted into the opening 40d so that the width direction of the base portion 67b coincides with the width direction of the opening 40d of the groove portion 40. Then, by rotating the wiring holding member 65 by 90 degrees, the base portion 67b of the claw portion 67a is engaged with the bottom portion 40c of the groove portion 40. At this time, the base 67b is slightly deformed. The distance between the outer surfaces of both base portions 67b is formed to be slightly larger than the width of the opening 40d of the groove portion 40. For this reason, the wiring pressing member 65 can be fixed without using a fixing tool or the like, and the wiring pressing member 65 can be prevented from moving.

  The wiring insertion portion 66 includes a vertical portion 66a extending downward from one end portion of the flat plate portion 67, a horizontal portion 66b extending in the horizontal direction from the lower end portion of the vertical portion 66a, and an inclined portion extending obliquely upward from the end portion of the horizontal portion 66b. 66c. The end of the inclined portion 66c is engaged with the upper surface of the mounting portion 41b. When the wiring holding member 65 is attached to the groove portion 40, a space is formed between one hanging portion 40 b of the groove portion 40, the support portion main body 41 a, and the top portion 36. Since wiring can be inserted into this space, this space can function as a wiring duct. Since this wiring space is located in front of the moving region of the door body 18, the workability of the wiring work can be improved.

  The wiring insertion portion 66 has two through holes 66d. The through hole 66d can be used to insert a binding member (not shown) for binding the wiring.

  The preliminary insertion portion 68 includes a first holding portion 68a and a second holding portion 68b. The first holding portion 68 a extends downward from the other end portion of the flat plate portion 67 in parallel with the vertical portion 46, and is bent toward the vertical portion 46 at the lower end portion thereof. The second holding portion 68b extends from the vertical portion 46 to the first holding portion 68a side. The tip of the first holding part 68a and the tip of the second holding part 68b are close to or in contact with each other. A space having a rectangular cross section is formed by the vertical portion 46 and the preliminary insertion portion 68 of the wiring insertion portion 66. This space can be preliminarily used as a space through which the wiring is inserted.

  As shown in FIG. 11, a wiring fixing member 69 for fixing the wiring can be attached to the fixed side member 32. The wiring fixing member 69 includes a screw member 69a, a plate-like fixing portion 69b, and a nut 69c. The screw member 69a has a head portion inserted into the groove portion 40 and a male screw portion. The fixing portion 69b has an insertion hole through which the male screw portion is inserted, and is disposed in contact with the bottom portion 40c of the groove portion 40 and the placement portion 41b. The nut 69c is screwed into the male screw portion. A binding member 70 for fixing the wiring can be wound around the fixing portion 69b. The fixed member 32 is formed with a through hole 32a for drawing the wiring out of the exterior body 21 (see FIGS. 2B and 11).

  In addition, the terminal block 72 can also be fixed to the groove part 40 (refer FIG. 2B). Similarly to the controller 56, the terminal block 72 can be attached to the groove portion 40 using the attachment member 73.

  As described above, in the present embodiment, the cover member 33 is fixed to the fixed side member 32 by the fixing means 34 while being pressed by the fixed side member 32 on the receiving surface 44. For this reason, even when the exterior body 21 is vibrated when the door 18 is driven by the drive mechanism 20, the cover member 33 and the fixed side member 32 vibrate integrally, so that the cover member 33 is fixed side member. It is possible to avoid vibration separately from 32. For this reason, it is possible to prevent the noise generated when the cover member 33 vibrates relative to the stationary member 32. Therefore, it is not necessary to use a gasket for preventing vibration (preventing noise) of the cover member 33. For this reason, it is possible to prevent noise while adopting a configuration in which the cover member 33 is attached to the fixed side member 32 in a state where no gasket is interposed.

  Moreover, in the present embodiment, when the cover member 33 is fixed to the fixed side member 32 by the fixing means 34 (see FIG. 7), the cover member 33 is elastically deformed. For this reason, the cover member 33 is fixed to the stationary member 32 by using a force that the cover member 33 attempts to return to the natural state. That is, the receiving surface 44 is pressed by the elastic force of the cover member 33. Therefore, it is possible to reliably prevent the cover member 33 from making a sound by vibrating relative to the stationary member 32.

  In the present embodiment, the cover 48 is in a state where the locked portion 48 is locked to the locking portion 42 of the fixed side member 32, and the screw hole 47 b is shifted from the position of the fastening hole 61 c of the fixed member 61.

In this embodiment, the side surface of the support portion 41 functions as a receiving surface 44 that is pressed from the cover member 33.

  In this embodiment, when the screw 62 inserted through the screw hole 47b of the cover member 33 is tightened into the fastening hole 61c of the fixing member 61, the cover member 33 is displaced upward as a whole. Along with this, the wedge portion 77 formed on the inner surface of the vertical portion 46 of the cover member 33 enters a clearance having a triangular cross section formed between the support portion 41 and the pressing portion 75 in the fixed side member 32. . The gap is formed in a triangular shape with a narrower width on the back side (upper side). For this reason, as the wedge portion 77 enters the back of the gap, the force that presses the side surface (receiving surface 44) of the support portion 41 increases. Therefore, in a state where the screw 62 is screwed into the fastening hole 61 c of the fixing member 61, a force is generated that the cover member 33 presses the receiving surface 44. In this state, the cover member 33 is fixed to the fixed side member 32. ing.
