The control device 33 performs drive control of the motor 31 and the like.

The rail base member 23 has a long shape in one direction extending in the moving direction of the door body 20. As shown in FIG. 2, the rail base member 23 includes a wall 39 fixed to a building frame or a frame member 37 fixed to the frame, and a rail projecting in a substantially horizontal direction from the lower end of the wall 39. And a support portion 40. A rail 40a on which a door wheel 41a provided on a door hanger 41 fixed to the door body 20 rolls is provided at the tip of the rail support portion 40. As shown in FIG. 2, the rail 40 a may be formed integrally with the rail support portion 40, or may be formed separately from the rail support portion 40 (not shown) and the rail support portion 40. It may be fixed to the tip.

The wall portion 39 includes an outer surface portion 43 that constitutes an outer surface on the rear surface side of the rail base member 23, and a fixing portion 44 provided on the front surface side of the outer surface portion 43. The fixing portion 44 includes a first side portion 45 formed to bend from the upper end of the outer surface portion 43 to the front surface side, and an intermediate portion in the height direction of the outer surface portion 43 (separated from the first side portion 45 in the height direction). 2nd side part 46 formed so that it might bend to a front side from a part). Both the first side portion 45 and the second side portion 46 are formed to extend in the length direction of the rail base member 23.

The first side portion 45 includes a bent portion 45a connected to the outer surface portion 43 and a front side portion 45b connected to the bent portion 45a. The bent portion 45a projects from the upper end of the outer surface portion 43 toward the front side. The front side portion 45b protrudes downward from the front end of the bent portion 45a. The front side portion 45b is parallel to the outer surface portion 43, and the bent portion 45a supports the front side portion 45b. The second side portion 46 includes a bent portion 46a connected to the outer surface portion 43 and a front side portion 46b connected to the bent portion 46a. The bent portion 46a projects from the intermediate portion of the outer surface portion 43 toward the front side. The front side portion 46b protrudes upward from the front end of the bent portion 46a. The front side portion 46b is parallel to the outer surface portion 43, and the bent portion 46a supports the front side portion 46b.

A gap extending in the moving direction of the door body 20 is formed between the lower end surface of the front side portion 45b of the first side portion 45 and the upper end surface of the front side portion 46b of the second side portion 46. Further, a space S extending in the moving direction of the door body 20 is formed between the front side part 45 b of the first side part 45 and the front side part 46 b of the second side part 46 and the outer surface part 43.

The fixing unit 44 can be used to fix the automatic door component device 48. Here, examples of the automatic door component device 48 include a motor 31, a control device 33, a terminal block 32, an electric lock (not shown), a battery (not shown), an inspection switch 51 (see FIG. 7), and the like. These devices 48 are attached to the rail base member 23 or are arranged in the vicinity of the rail base member 23. These devices 48 are devices for operating the automatic door device 10 or devices for controlling the operation of the automatic door device 10, and are devices that need to be grounded or devices that are preferably grounded. These devices 48 are supplied with commercial power or power transformed from commercial power. The automatic door component 48 is connected to a bracket made of a conductor (metal or the like) to which the ground wire 28 is electrically connected, a conductive bracket for fixing the motor 31 or the like, and the rail base member 23. Other rail base members 23 and the like are also included.

For example, FIG. 2 shows a state when the motor 31 is fixed to the fixing portion 44, and FIG. 3 shows a state when the terminal block 32 is fixed to the fixing portion 44. In order to fix the motor 31, a plate-like support member 53 (motor bracket) to which the motor 31 is fixed and a plate-like fixing member 54 are used. The fixing member 54 is inserted into the space S between the outer surface portion 43 and the

front side portions

45b and 46b. The

front side portions

45b and 46b are sandwiched between the fixing member 54 and the support member 53 positioned in front of the

front side portions

45b and 46b. In this state, the motor 31 is fixed to the fixing portion 44 of the rail base member 23 by fastening the fixing member 54 and the support member 53 to each other.

When the terminal block 32 is fixed, it can be fixed in the same manner. That is, the

front side portions

45b and 46b of the fixing portion 44 are sandwiched between the base 32a of the terminal block 32 and the fixing member 54, and in this state, the base 32a and the fixing member 54 are fastened to each other, thereby 32 can be fixed to the fixing portion 44 of the rail base member 23.

The rail base member 23 includes a conductive base material 23a (see FIG. 5) and an electrical insulating layer (hereinafter also referred to as an insulating layer) 23b formed on the surface of the base material 23a. The insulating layer 23b includes an alumite film (corrosion-resistant film, wear-resistant film) when the base material 23a is made of aluminum, and a paint film when the base material 23a is made of metal (stainless steel, iron-based material, aluminum, etc.) This corresponds to an oxide film in the case where the base material 23a is made of aluminum. These are all electrically insulating films.

In the first embodiment, the conductive base material 23a of the rail base member 23 is used as a conductor for grounding. Thereby, the number of wirings of the ground line 28 can be reduced, and the labor of wiring of the ground line 28 can be suppressed. This point will be specifically described below.

The terminal block 32 has a base 32a and a terminal portion 32b fixed to the base 32a. A ground wire 28 is electrically connected to the base 32 a of the terminal block 32. One end of the ground wire 28 is grounded. The other end of the ground wire 28 is connected to the base 32 a by a ground terminal 55. The base 32 a is electrically connected to the fixing member 54 via a bolt 56 that fastens the base 32 a and the fixing member 54. The terminal block 32 is connected not only to the ground line 28 but also to other electric lines (power line and signal line).

The fixing member 54 is made of an iron-based material. When the insulating layer 23b of the rail base member 23 is a coating film, the fixing member 54 may be copper, aluminum, or the like.

As shown in FIGS. 4A and 4B, the fixing member 54 is provided with a screw hole 54a and a protrusion 54b. The screw hole 54 a is used for screwing a bolt 56 that fastens the base 32 a and the fixing member 54. As the bolt 56 is screwed into the screw hole 54a, the protrusion 54b breaks the insulating layer 23b of the rail base member 23 and reaches the base material 23a. And as shown in FIG. 5, the protrusion 54b is arrange | positioned over the surface by the side of the base material 23a in the insulating layer 23b from the surface (surface on the opposite side to the base material 23a) of the insulating layer 23b. Thereby, the base material 23a of the rail base member 23 is in a state in which it can be electrically connected to the base 32a of the terminal block 32 via the fixing member 54. That is, the protrusion 54b functions as an insulating layer penetrating portion that penetrates the insulating layer 23b. In other words, the insulating layer 23b is destroyed at a portion where the protrusion 54b penetrates the insulating layer 23b. As a result, the base material 23a of the rail base member 23 is grounded.

On the other hand, a grounding wire 57 connected to the motor 31 is electrically connected to the support member 53 of the motor 31. That is, the support member 53 is a member that can be electrically connected to the motor 31. The fixing member 54 for fixing the motor 31 has the same configuration as the fixing member 54 used for fixing the terminal block 32. Therefore, when the support member 53 and the fixing member 54 are fastened to each other by the bolt 58, the protrusion 54b of the fixing member 54 breaks through the insulating layer 23b of the rail base member 23. That is, the protrusion 54b functions as an insulating layer penetrating portion that penetrates the insulating layer 23b. As a result, the support member 53 is electrically connected to the base material 23 a of the rail base member 23 via the fixing member 54. As a result, the motor 31 can be grounded without connecting the motor 31 to the terminal block 32 with an electric wire.

As shown in FIGS. 4A and 4B, the protrusions 54b are provided at two locations in the diagonal direction at the four corners. However, the positions of the protrusions 54b are not limited to the two corners. The protrusion 54b may be at any position as long as it is in a position facing the fixing portion 44 of the rail base member 23. Further, the number of the protrusions 54b is not limited to two, and may be one or three or more.

The protrusions 54b may be provided on both surfaces of the fixing member 54 as shown in FIG. If it does so, the front and back of the fixing member 54 will be lost, and when using the fixing member 54, the operation | work which checks the presence or absence of the protrusion 54b of an operator becomes unnecessary. Since the projection 54b may be very small, the burden of the fixing operation of the automatic door component device 48 can be reduced if the confirmation operation is unnecessary. In this case, the protrusion 54b arranged on one surface does not have a role of penetrating the insulating layer 23b.

Further, the protrusion 54 b may be provided on the support member 53 instead of being provided on the fixing member 54. Further, it may be provided on the base 32 a of the terminal block 32. The protrusion 54b in this case may be provided anywhere as long as the position faces the fixing portion 44 of the rail base member 23.

When manufacturing the automatic door device 10 of the first embodiment, the automatic door constituting device 48 such as the motor 31, the control device 33, the terminal block 32, etc. is attached to the rail base member 23. At this time, the insulating layer 23b is destroyed by the protrusion 54b, and the base material 23a of the rail base member 23 and at least one automatic door constituting device 48 are brought into conduction. Then, necessary wiring is performed. Thereby, the automatic door apparatus 10 is completed. At the construction site, for example, the ground wire 28 is connected to the terminal block 32 so that one of the base material 23a of the rail base member 23 and the automatic door component device 48 is grounded via the other. Thereby, each automatic door component apparatus 48 will be in the state earth | grounded.

As described above, in this embodiment, the protrusion 54b penetrates the electrical insulating layer 23b of the rail base member 23. Thereby, the automatic door component 48 and the base material 23a of the rail base member 23 are electrically connected. One of the rail base member 23 and the automatic door constituting device 48 is grounded via the other. Therefore, the electrical wiring for grounding the automatic door component 48 or the rail base member 23 can be reduced. As a result, the work for grounding can be facilitated. In addition, since the protrusion 54b is in a state of penetrating the insulating layer 23b, electrical connection between the rail base member 23 and the automatic door constituting device 48 can be reliably performed.

In the first embodiment, the protrusion 54b penetrates the insulating layer 23b while physically destroying it. For this reason, the pretreatment for the protrusion 54b to penetrate the insulating layer 23b becomes unnecessary. Therefore, the connection work between the base member 23a of the rail base member 23 and the automatic door constituting device 48 can be facilitated.

In the first embodiment, the automatic door constituting device 48 and the rail base member 23 can be brought into conduction by attaching the automatic door constituting device 48 to the rail base member 23. Therefore, the electrical connection work can be performed simultaneously with the mounting work of the automatic door component device 48.

Further, when the protrusions 54b are provided at a plurality of locations such as the fixing member 54, adverse effects due to the mounting state of the automatic door constituting device 48 or the fixing member 54 can be suppressed.

In addition, when the protrusions 54b are provided on the front surface and the back surface of the fixing member 54, the insulating layer 23b can be destroyed by the protrusions 54b without being affected by the orientation when the fixing member 54 is attached. Therefore, an adverse effect due to a mounting error of the fixing member 54 can be suppressed.

In addition, although 1st Embodiment demonstrated the electrical connection of the terminal block 32 and the motor 31 via the rail base member 23, it is not restricted to this. For example, the terminal block 32 and the inspection switch 51 (see FIG. 7) may be electrically connected via the rail base member 23. The inspection switch 51 is also included in the concept of the automatic door component device 48. As shown in FIG. 7, the inspection switch 51 is fixed to the rail base member 23 by fixing the switch support plate 60 that supports the inspection switch 51 to the rail support portion 40 by the fixing member 54. The switch support plate 60 is connected to an electrical wire 61 for grounding the inspection switch 51 and has an insertion hole (not shown) through which the bolt 62 is inserted.

The fixing member 54 is formed with a concave portion 54c corresponding to the shape of the rail support portion 40. The bottom surface of the concave portion 54c functions as an insulating layer penetrating portion that penetrates the insulating layer 23b of the rail base member 23. A protrusion 54b is formed. The rail support portion 40 can be held between the fixing member 54 and the switch support plate 60 by screwing the bolt 62 inserted into the insertion hole of the switch support plate 60 into the screw hole 54 a of the fixing member 54. At this time, the protrusion 54b breaks through the insulating layer 23b, and the switch support plate 60 and the base material 23a of the rail base member 23 can be electrically connected.

In the first embodiment, the protrusion 54b is provided on the fixing member 54. However, the present invention is not limited to this. For example, the protrusion 54 b may be provided on the support member 53 of the motor 31, or may be provided on both the fixing member 54 and the support member 53. The protrusion 54b may be provided on the base 32a of the terminal block 32, or may be provided on both the fixing member 54 and the base 32a. That is, the automatic door component device 48 may be provided.

In the first embodiment, the fixing portion 44 capable of fixing the automatic door component device 48 is provided on the wall portion 39 fixed to the building frame, but is not limited thereto. For example, as shown in FIG. 8, the rail base member 23 includes a wall 39 fixed to a building frame or a frame material 37 fixed to the frame, and a top 65 extending horizontally from the upper end of the wall 39. And. And the cover member 66 is connected with the top part 65 of the rail base member 23 so that rotation is possible. The cover member 66 is formed in a shape that covers the automatic door constituting device 48 such as the motor 31 and the control device 33 fixed to the rail base member 23.

The rail support portion 40 is connected to the lower end portion of the wall portion 39. On the other hand, the fixing portion 44 is provided not on the wall portion 39 but on the top portion 65. That is, the top portion 65 includes an outer surface portion 43 that forms an outer surface on the upper surface side of the rail base member 23, and a fixing portion 44 that is provided on the lower surface side of the outer surface portion 43.

The fixing portion 44 bends downward from a first side portion 45 formed to bend downward from one portion of the outer surface portion 43 and a second portion that is separated in the width direction from the partial position of the outer surface portion 43. And a second side portion 46 formed on the surface. The first side portion 45 includes a bent portion 45a connected to the outer surface portion 43 and a front side portion 45b connected to the bent portion 45a. The bent portion 45a protrudes downward from the outer surface portion 43. The front side portion 45b protrudes sideways from the lower end of the bent portion 45a. The second side portion 46 includes a bent portion 46a connected to the outer surface portion 43 and a front side portion 46b connected to the bent portion 46a. The bent portion 46a projects downward from a position away from the bent portion 45a. The front side portion 46b protrudes sideways from the lower end of the bent portion 46a. A gap extending in the moving direction of the door body 20 is formed between the front side portion 45 b of the first side portion 45 and the front side portion 46 b of the second side portion 46. Further, a space S extending in the moving direction of the door body 20 is formed between the front side part 45 b of the first side part 45 and the front side part 46 b of the second side part 46 and the outer surface part 43. And the fixing member 54 used in order to fix the automatic door components 48, such as the motor 31, is arrange | positioned in this space S. FIG.

The fixing member 54 is formed of a rectangular flat plate material as shown in FIG. Projections 54 b are formed at corners on at least one surface of the fixing member 54. The protrusion 54b is in a state of penetrating the insulating layer 23b of the rail base member 23. If the ground wire 28 is electrically connected to the fixing member 54, the connection point of the ground wire 28 can be located near a place where a large current such as the motor 31 may leak. By doing so, the possibility of electric shock can be further reduced.

(Second Embodiment)
10A and 10B show a second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same component as 1st Embodiment here, and the detailed description is abbreviate | omitted.

In the second embodiment, the protrusion 54b is formed in an annular shape. That is, when the protrusion 54b is viewed from the tip side, the protrusion 54b looks like an annular shape. However, it is not limited to an annular shape. The outer peripheral surface of the protrusion 54b may be perpendicular to the surface 54c of the fixing member 54, or may be inclined so that the width of the protrusion 54b becomes narrower toward the front side. The inner peripheral surface of the protrusion 54b is inclined so that the protrusion 54b becomes thinner toward the front side of the protrusion 54b. The inclination angle of the inner peripheral surface (inclination angle with respect to the direction perpendicular to the surface 54c) may be larger than the inclination angle of the outer peripheral surface. In order to form the protrusion 54b having such a shape, a raised portion is formed on one main surface (surface 54c) of the fixing member 54, and this portion is pressed with a tool whose tip is rounded such as a punch. That's fine. This tool press can be performed, for example, in the same process as the press work in the punching process of the fixing member 54. 10A and 10B show only a part of the fixing member 54. FIG. Accordingly, the protrusion 54 b is formed only on a part of the fixing member 54.

As shown in FIGS. 11A and 11B, the protrusion 54b may be formed in a convex shape that does not have an inner peripheral surface, instead of an annular shape. 12A and 12B, the protrusion 54b may be formed at the end of the fixing member 54. In this case, the protrusion 54 b may be formed in a shape that bends from the end of the fixing member 54. Further, the protrusion 54b may be constituted by a burr formed when the fixing member 54 is press-molded. Further, the protrusion 54b may be a tooth portion of a toothed washer (not shown). In this case, the toothed washer is disposed at a position where the through hole of the toothed washer allows the bolt to pass, and the toothed washer is sandwiched between the fixing member 54 and the fixing portion 44 of the rail base member 23 to thereby fix the fixing member. 54 is provided with a protrusion 54b.

As shown in FIG. 13, the protrusions 54 b may be formed at the four corners of the fixing member 54. In this case, by arranging a plurality of protrusions 54b, even if one point does not conduct, an effect that can be covered by another can be obtained.

The other configurations, operations, and effects are the same as those in the first embodiment, although explanations thereof are omitted.

(Third embodiment)
14A and 14B show a third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same component as 1st Embodiment here, and the detailed description is abbreviate | omitted.

In the third embodiment, unlike the first embodiment, the automatic door constituting device 48 is fixed by relatively displacing the fixing member 54 to which the automatic door constituting device 48 is fixed with respect to the rail base member 23. The fixing member 54 is connected to grounding wiring (not shown) connected to the automatic door constituting device 48. FIG. 14B shows a control device 33 as an example of the automatic door component device 48.

The fixing member 54 is provided with a screw hole 54 a that is screwed into the male screw portion of the screw 68. The front end surface 68 a of the screw 68 screwed into the screw hole 54 a contacts the inner surface of the outer surface portion 43 of the rail base member 23. When the screw 68 is further screwed in this state, the fixing member 54 presses the first side portion 45 and the second side portion 46 of the fixing portion 44 from the outer surface portion 43 side so as to leave the outer surface portion 43.

A protrusion 54 b is provided at a portion of the fixing member 54 that faces the first side portion 45 and the second side portion 46. For this reason, the protrusion 54b destroys the insulating layer 23b of the rail base member 23 by screwing of the screw 68. Thereby, the fixing member 54 and the base material 23a of the rail base member 23 can be electrically connected. Even in this configuration, the protrusion 54b functions as an insulating layer penetrating portion that penetrates the insulating layer 23b. Note that the screw 68 may not have electrical conductivity.

In the case of FIG. 14B, the protrusion 54b penetrates the insulating layer 23b by tightening the screw 68 to fix the control device 33 by the fixing member 54. For this reason, the pre-processing work for the protrusion 54b to penetrate the insulating layer 23b becomes unnecessary. Therefore, the connection work between the base member 23a of the rail base member 23 and the automatic door constituting device 48 can be facilitated. Further, electrical connection can be performed without adversely affecting the strength of the rail base member 23.

Note that the protrusion 54 b may be provided not on the fixing member 54 but on a portion of the first side portion 45 and the second side portion 46 that faces the fixing member 54.

As shown in FIGS. 15A and 15B, the protrusion 54b may not be provided. In this modification, the fixing member 54 is pressed against the fixing portion 44 of the rail base member 23 while pressing the outer surface portion 43 of the rail base member 23 with the tip of the screw 68. For this reason, the insulating layer 23b at the position pressed by the tip surface 68a of the screw 68 may be gradually removed from the portion by the screwing of the screw 68. In this case, the screw 68 is a conductive screw 68. The conductive screw 68 is not limited to the one in which the screw 68 itself is made of a conductive material, and the portion that contacts the automatic door constituting device 48 or the fixing member 54 and the base 23 a of the rail base member 23. The part which contacts has electroconductivity and should just be the structure electrically connected between both.

When the insulating layer 23b located at the tip of the screw 68 is removed from the place where it contacts the tip surface 68a, the screw 68 and the base material 23a of the rail base member 23 are in a conductive state. Since the screw 68 is in a state where it can be electrically connected to the fixing member 54, the controller 33 and the base material 23 a of the rail base member 23 can be electrically connected. Even in this case, it can be said that the insulating layer 23b is broken at a portion penetrating the insulating layer 23b. In other words, the screw 68 functions as an insulating layer penetrating portion that penetrates the insulating layer 23b.

In the case of FIG. 15B, the rail base member 23 having the electrical insulating layer 23b and the automatic door component device 48 are in a conductive state in the process of attaching the automatic door component device 48 to the rail base member 23. Therefore, the connection work can be performed simultaneously with the mounting work.

(Fourth embodiment)
FIG. 16 shows a fourth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same component as 1st Embodiment here, and the detailed description is abbreviate | omitted.

The fourth embodiment is an example in which the penetrating member 70 connected to the ground line 28 penetrates the insulating layer 23b of the rail base member 23. The ground line 28 is connected to, for example, the ground or a building frame electrically connected to the ground, and has almost no potential difference from the ground.

The penetrating member 70 is, for example, a conductive screw (tapping screw). When the penetrating member 70 reaches the base material 23a while destroying the insulating layer 23b of the rail base member 23 by the penetrating member 70, the base material 23a of the rail base member 23 is grounded. The penetrating member 70 functions as an insulating layer penetrating portion that penetrates the insulating layer 23b. If the automatic door constituting device 48 is fixed to the rail base member 23 by the method described in the first to third embodiments, the automatic door constituting device 48 causes the base member 23a and the penetrating member 70 of the rail base member 23 to move. Through the ground. For example, as shown in FIG. 17, the control device 33, which is an example of the automatic door component device 48, is in a conductive state with the penetrating member 70 via the base material 23 a of the rail base member 23.

Further, the control device 33 may be fixed to the rail base member 23 by a conductive screw 69. The screw 69 is fixed in a conductive state with the control device 33 and is in a state of penetrating the insulating layer 23b of the rail base member 23. In this case, the screw 69 functions as an insulating layer penetrating portion that penetrates the insulating layer 23b.

In FIG. 17, the electric lock 71, which is an example of the automatic door component device 48, is connected to the penetrating member 70 by being connected by the penetrating member 70 and the wiring 72. However, the present invention is not limited to this. The electric lock 71 may also be electrically connected to the penetrating member 70 via the base material 23a of the rail base member 23.

The position where the penetrating member 70 is fixed to the rail base member 23 may be anywhere. Since the end surface in the length direction of the rail base member 23 is a cut surface and there is no anodized coating, the penetrating member 70 may be fixed to that portion. In this case, it does not penetrate the alumite coating (insulating layer 23b). Of course, the penetrating member 70 may penetrate the alumite coating and reach the base material 23a.

FIG. 16 shows a case of a one-way automatic door device that opens and closes one door body 20. For this reason, one rail base member 23 is provided. On the other hand, as shown in FIG. 18, when a pair of rail base members 23 are provided, one rail base member 23 (first rail base member 23 A) is electrically connected to the ground line 28 through the penetrating member 70. It will be in the state. The first rail base member 23 A and the other rail base member 23 (second rail base member 23 B) may be connected by an electric wire 72. A penetration member 70 is provided at both ends of the electric wire 72 and penetrates the insulating layer 23 b of the rail base member 23. The second rail base member 23 is also included in the concept of the automatic door component device 48.

As shown in FIG. 19, the second rail base member 23 B may be electrically connected to the first rail base member 23 A by the connection bracket 25. An unillustrated penetrating member is fastened to reach the base material 23a of the rail base member 23, and the connection bracket 25 is fixed to the

rail base members

23A and 23B via the penetrating member. Thereby, the connection bracket 25 and each

rail base member

23A and 23B are in the state which can be conduct | electrically_connected. The penetrating member 70 may be constituted by a conductive screw (tapping screw).

As shown in FIG. 20, each of the first rail base member 23 A and the second rail base member 23 B can be electrically connected to the ground wire 28 through the penetrating member 70 connected to the ground wire 28. Good.

Instead of the configuration in which the base material 23a of the rail base member 23 is grounded via the penetrating member 70, the base material 23a of the rail base member 23 may be grounded via the grounded terminal block 32. That is, the base material 23a of the rail base member 23 may be in a state where it can be electrically connected to the terminal block 32 via the fixing member 54 as described in the first embodiment. For this reason, as shown in FIG. 21, the automatic door component device 48 (for example, the control device 33) is in a state in which it can be electrically connected to the terminal block 32 through the base material 23 a of the rail base member 23, thereby Has been. Alternatively, the automatic door component device 48 may be in a state where it can be electrically connected to the base material 23b of the rail base member 23 by a conductive screw. On the other hand, the other automatic door constituting device 48 (for example, the motor 31) may be grounded by being connected to the terminal block 32 by the electric wire 73.

In FIG. 22, a penetrating member 70 (for example, a tapping screw) is connected to a grounding wire 74 provided in an automatic door constituting device 48 such as a motor 31, and the penetrating member 70 is an insulating layer of the rail base member 23. In this example, the automatic door constituting device 48 is grounded by passing through 23b. In this case, any method may be used for grounding the base material 23a of the rail base member 23.

FIG. 23 shows the automatic door constituting device 48 and the base material of the rail base member 23 when the automatic door constituting device 48 such as the motor 31 is fixed to the rail base member 23 via a non-conductive member. This is an example in the case of conducting with 23a. As shown in FIG. 23, when a pair of

conductive sprockets

76 and 77 and a conductive chain 78 are used, a member (not shown) for supporting one sprocket (first sprocket) 76 has an insulating layer penetrating portion. (Not shown) that functions as Therefore, the first sprocket 76 is in a state where it can be electrically connected to the base material 23a of the rail base member 23 through this protrusion. The other sprocket (second sprocket) 77 is in a state where it can be electrically connected to the first sprocket 76 via the chain 78. The second sprocket 77 is slidably in contact with a ground terminal (not shown) provided in the automatic door component device 48. Thereby, the automatic door component device 48 is in a state in which it can be electrically connected to the base material 23a of the rail base member 23 via the second sprocket 77, the chain 78, and the first sprocket 76.

In the fifth embodiment, a part of the insulating layer 23b of the rail base member 23 is physically removed by a file, sandpaper, or the like. The part from which the insulating layer 23 b is removed is, for example, a part facing the fixing member 54 in the fixing part 44, or a part facing the conductive part in the automatic door component device 48. And the automatic door structure apparatus 48 and the base material 23a of the rail base member 23 can conduct | electrically_connect using the site | part from which the insulating layer 23b was removed. On the other hand, the base member 23a of the rail base member 23 is grounded by the penetrating member 70 connected to the ground line 28 penetrating the insulating layer 23b. As a result, the automatic door constituting device 48 is in a grounded state. When the automatic door component device 48 is grounded, the penetrating member 70 connected to the ground wire 28 may not be connected to the base material 23a of the rail base member 23.

In the fifth embodiment, a part of the insulating layer 23b is removed by a file or the like. Thereafter, the base 23a of the rail base member 23 and the automatic door constituting device 48 are brought into conduction by utilizing the region without the insulating layer 23b. Thereby, the automatic door apparatus 10 is completed. Then, at the construction site of the automatic door device 10, one of the base material 23a of the rail base member 23 and the automatic door component device 48 is grounded via the other.

Note that the method is not limited to the method of physically removing one region of the insulating layer 23b. Alternatively, a region of the insulating layer 23b may be removed by chemically reacting the insulating layer 23b. For example, a region of the insulating layer 23b may be destroyed with chemicals, and the insulating layer 23b in that portion may be removed. More specifically, when the insulating layer 23b is an alumite coating, chemicals such as caustic soda, hydrochloric acid, benzene, and rising water can be used. When the insulating layer 23b is a coating film, the insulating layer 23b can be removed with an organic solvent.

FIG. 25 shows an example in which the insulating layer 23b is removed where the base 32a of the terminal block 32 is attached. The method for removing the insulating layer 23b is as described above. Then, the ground wire 28 may be connected to the terminal block 32. On the other hand, even when the automatic door component device 48 other than the terminal block 32 is attached, the insulating layer 23b is removed, or the protrusion 54b that functions as the insulating layer penetrating portion penetrates the insulating layer 23b. Also good.
