DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing apparatus for a sliding door used indoors of a house, for example.

[0002]

2. Description of the Related Art Conventionally, as this type of automatic opening / closing device for a sliding door, for example, one disclosed in Japanese Utility Model Publication No. 7-52310 is known. This automatic opening / closing device is configured by housing a drive device such as a motor, a speed reduction mechanism, and a controller in an engine box disposed above a sliding door body. The engine box has an outdoor cover plate and
It comprises a base plate on the indoor side, and a pair of left and right attachment members that are located at the outer ends of the cover plate and the base plate and that attach these to the vertical frame of the sliding door frame. In this case, the cover plate decorates the exterior of the engine box and also serves as an inspection door of the drive device, and the base plate decorates the interior of the engine box and also serves as a support member of the drive device.

Each mounting member is fixed to a vertical frame, and a pair of mounting protrusions for mounting a cover plate and a pair of mounting protrusions for mounting a base plate are formed on the surface of the mounting member. The base plate is screwed to the pair of mounting protrusions from the inside, and the cover plate is screwed to the pair of mounting protrusions from the outside. Therefore, the mounting screws are hidden on the base plate side, but are exposed on the cover plate side.

[0004]

In such a conventional automatic opening / closing device for a sliding door, the driving device is covered from inside and outside the room by a cover plate and a base plate. When maintenance is performed, the driving device also serves as an inspection door. Remove the cover plate. That is, maintenance of the driving device is performed from one side of the driving device. For this reason, it is difficult to perform maintenance at a portion located on the base side of the drive device, and it is necessary to arrange components of the drive device in consideration of maintenance from one direction, and the drive device is structurally limited. There was a problem.

An object of the present invention is to provide an automatic opening / closing device for a sliding door in which the driving device is not restricted in structure and can improve the maintainability of the driving device.

[0006]

SUMMARY OF THE INVENTION An automatic sliding door opening and closing apparatus according to the present invention is an automatic sliding door opening and closing apparatus for opening and closing a sliding door body mounted on a sliding door frame. An engine unit that opens and closes, an indoor cover that covers the engine unit from the indoor side, an outdoor cover that covers the engine unit from the outdoor side, and a cover mounting member for attaching the indoor and outdoor cover to the sliding door frame. And the cover mounting member is detachably mounted in a fitting manner.

[0007] According to this configuration, the outdoor cover and the indoor cover that cover the engine unit are detachably attached to the cover mounting member in a fitting manner, so that both the outdoor cover and the indoor cover are easily attached. When the inner and outer covers are removed, at least the front and back surfaces of the engine unit are exposed, making maintenance extremely easy. In addition, by making the outdoor cover and the indoor cover a detachable structure with a fitting type,
The mounting screws are not exposed, and the design is good.

In this case, it is preferable that the sliding door is a single sliding door, and the main drive unit of the engine unit is disposed at a portion facing the opening of the single sliding door.

The width of the single sliding door in the expected direction of the sliding door frame is approximately twice as large as the opening between the opening and the retracted portion. For this reason, by disposing the main drive unit of the engine unit in the opening, it can be disposed in a large space with depth, and the space inside the indoor and outdoor covers can be effectively utilized. At the same time, the degree of freedom in arranging the components of the main drive unit itself can be increased.

In these cases, each of the indoor and outdoor covers preferably has a cover body and an engaging member fixed to the inner surface of the cover body and engaged with and disengaged from the cover mounting member.

According to this structure, since each of the indoor and outdoor covers has the cover main body and the engaging member, the cover main body can be constituted by a member mainly composed of decoration, while the engaging member is It can be composed of a member mainly having an engagement / disengagement structure. Therefore, both the inner and outer covers can have both good engagement and disengagement functions and good decorativeness.

In these cases, the cover mounting member includes a pair of left and right outdoor cover mounting members to which the outdoor cover is attached at both outer ends and which is fixed to the vertical frame of the sliding door frame. It has a pair of left and right indoor cover mounting members that are attached and fixed to the vertical frame of the sliding door frame, and each indoor and outdoor cover mounting member is formed in a symmetrical shape toward the engaging member, preferable.

According to this configuration, the cover mounting member has the pair of left and right outdoor cover mounting members for the outdoor cover and the pair of left and right indoor cover mounting members for the indoor cover. Can be firmly attached with both ends, and the indoor and outdoor covers can be attached to arbitrary positions in the expected direction. In addition, since each of the indoor and outdoor cover mounting members is formed in a symmetrical shape toward the engagement member, the right and left hands may be generated when the indoor and outdoor cover mounting members are used by inverting left and right. Instead, the indoor and outdoor cover mounting members can be formed of the same shape.
