[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an engine case of an automatic door.

[0002]

2. Description of the Related Art A drive pulley and a driven pulley are mounted on an engine case, a belt is wound around the drive pulley and the driven pulley, a suspension mounted on a door is brought into contact with a rail upper surface of the engine case, and the door and the belt are connected. 2. Description of the Related Art There is known an automatic door in which a drive pulley is driven by a motor to move the door along a rail of an engine case. In such an automatic door, when vibration of a drive unit such as a motor and a drive pulley is transmitted to a vertical frame supporting an engine case, the vibration is transmitted to a building to which the automatic door is attached and noise is generated. As shown in Japanese Patent Application Laid-Open No. 61-117877, an engine case is mounted through a cushioning material so as to prevent the vibration of the drive unit from being transmitted to the vertical frame. I have to.

[0003]

However, when the door of the automatic door is suspended from the engine case in a cantilever state, the load is applied to the engine case in a direction inclined by the weight of the door itself. Is to be fixed to the vertical frame via the cushioning material at both ends by the mounting bolts. In such a case, the vibration generated in the engine case is transmitted to the vertical frame via the mounting bolts. .

Accordingly, an object of the present invention is to provide an engine case mounting structure for an automatic door which can solve the above-mentioned problems.

A side plate is attached to the longitudinal end of the engine case, and a support bracket is attached to the vertical frame so as to face the vertical end surface of the side plate, between the support bracket and the vertical end surface of the side plate and to the side plate. With cushioning material interposed between the vertical frame.

[Operation] The engine case can be prevented from tilting and vibration can be prevented from being transmitted to the vertical frame.

[0005]

[Embodiment] As shown in FIG. 1, a blind 2 is connected to a vertical frame 1 by a screw, and the blind 2 is composed of a vertical plate 3 and upper and lower horizontal plates 4,5.
, A cover 6 is attached to the upper horizontal plate 4, and a gap 7 is formed between the lower horizontal plate 5 and the cover 6.
An engine case 10 is provided in the blind 2, and the engine case 10 is formed into a U-shaped long material by a vertical plate 11 and upper and lower horizontal plates 12 and 13, and a rail 14 is provided at an opening end of the lower horizontal plate 13. Are provided integrally, and a suspension wheel 17 is attached to the door 15 via a hanger 16, and the suspension wheel 17 is in contact with the upper surface of the rail 14 to suspend the door 15 in a cantilever state. A side plate 18 is attached to the longitudinal end of the engine case 10 with screws or the like.
The upper and lower support brackets 19 face the upper and lower sides of the vertical end face on the opening side,
Numerals 20 are attached to the vertical frame 1 with bolts 21, respectively, and cushioning members 22 are provided between the upper and lower support members 19, 20 and the vertical end surfaces of the side plates 18 and between the side plate 18 and the vertical frame 1.
The upper and lower support brackets 19 and 20 include a mounting piece 23 and a holding piece 24.
As shown in FIG. 2, the attachment piece 23 is attached to the vertical frame 1 via bolts 21 via the back plate 25, the pressing piece 24 faces the vertical edge of the side plate 18, and the lower support fitting 20 The cover 6 is attached with screws 27 as shown in FIG. 3, and the cushioning member 22 is composed of a vertical plate-like portion 28 and upper and lower horizontal portions 29, 29, as shown in FIG. The vertical plate-like portion 28 is pressed between the side plate 18 and the vertical frame 1, and the upper and lower horizontal pieces 29, 29 are connected to the vertical edge of the side plate 18 and the upper and lower support fittings 1.
It is press-fitted between the holding pieces 24 of 9, 20. Reference numeral 30 denotes a notch for passing an electric wire, and an electric wire is disposed in the notch 30 in the electric wire passage hole 31 of the vertical frame 1. A cushioning material 32 is interposed between the seamless vertical plate 3 and lower horizontal plate 5 and the vertical plate 11 and lower horizontal plate 13 of the engine case 10, respectively. The upper and lower support members 19 and 20 may be integrated.

[0006]

[Effect of the Invention] The inclination of the engine case 10 is adjusted by the side plate 18,
It can be prevented by the cushioning material 22 and the supporting bracket, and only the cushioning material is provided between the side plates 18 attached to both longitudinal ends of the engine case 10 and the vertical frame 1, and the vibration from the engine case 10 is transmitted to the vertical frame 1. Can be prevented.
