Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure in which an engine case equipped with a drive device for an automatic opening / closing door is directly attached to the upper edge side body of a building opening.

[Conventional technology]

For example, automatic opening / closing doors used for entrance / exit openings in buildings such as factories and warehouses are constructed by winding a belt around a drive pulley and a driven pulley driven by a motor, connecting the door to the belt, and driving the motor to drive the door. Are automatically opened and closed, and the drive devices such as the motor, drive pulley, and driven pulley are attached to the engine case, and the engine case is generally attached to the upper edge side frame of the building opening.

[Problems to be solved by the device]

In the engine case of the type described above, the drive device generates mechanical vibrations when the door is opened and closed, and this mechanical vibration is a problem that noise is generated in the building through the upper edge side body of the building opening.

Further, in order to absorb such mechanical vibration, a well-known anti-vibration technique of a type in which the engine case is mounted in a seamless manner, that is, various components constituting a drive device mounted in the engine case are made of rubber. It is also conceivable to use a technique of attaching to the engine case via the. However, since there are many parts that make up the drive unit and the shapes are also various, there are many types of vibration-proof materials to be attached to these parts, which complicates inventory management of parts or requires time and effort to install the vibration-proof materials. Therefore, there is a problem in cost.

Therefore, the present invention solves the above-mentioned problems, and the engine case of the automatic opening / closing door can be mounted on the upper edge side body of the building opening so as to be stable and vibration-proof, and the cost of the automatic door engine is low. The purpose is to provide a case mounting structure.

[Means and Actions for Solving the Problems]

The first mounting bracket with the anti-vibration rubber facing upward and the second mounting bracket with the lateral anti-vibration rubber are mounted on the upper edge side body of the building opening, and the horizontal support part of the hanging bracket mounted on the upper part of the engine case. Is mounted on the anti-vibration rubber of the first mounting bracket and connected, and the upper and lower intermediate portions of the engine case are contacted and connected to the anti-vibration rubber of the second mounting bracket to stabilize the engine case on the body. It is designed so that it can be installed in a vibration-proof manner.

(Outline of automatic opening / closing door) As shown in FIG. 2, a pair of doors 2 and 2 are supported along an engine case 1 via a hanging door vehicle 3 so as to be able to travel left and right,
The motor attached to the engine case 1, the drive pulley,
An automatic opening / closing door is configured such that a pair of doors 2, 2 can be automatically opened / closed by a driving device 4 such as a driven pulley and a belt.

(Shape of Engine Case) As shown in FIG. 1, the engine case 1 includes an upper horizontal plate.
10, the vertical plate 11 and the lower horizontal plate 12 have a horizontally long cross-section that is roughly U-shaped,
The lower horizontal plate 12 is integrally provided in the rail portion 13 in the longitudinal direction to guide the hanging door car 3 so that it can travel freely, and the drive device 4 is attached to the vertical plate 11, and the engine case 1 has the ceiling plate 5
It is arranged higher and is attached to the upper edge side body A of the building opening in a vibration-proof manner.

A guide pin 6 is provided at the bottom of the door 2 so that the floor 7
The vehicle is guided along the guide groove 8 of FIG.

(Engine case mounting structure) As shown in FIGS. 1 and 3, a plurality of L-shaped upper horizontal reinforcing pieces 15 and lower horizontal reinforcing pieces 16 are longitudinally formed on the upper and lower edges of the vertical plate 14 by welding or the like. Are fixed to each other at predetermined intervals to form a support bracket 17, and the vertical plate 14 of the support bracket 17 is connected to the vertical plate 11 of the engine case 1 with a bolt 19 via a vibration-proof rubber 18 and is provided below the vertical plate 14. The lower lateral plate 12 of the engine case 1 is connected to a support piece 20 fixed by welding or the like by a bolt 22 via a vibration-proof rubber 21 so that the engine case 1 is vibration-proofly attached to the support fitting 17.

A lower horizontal piece 24 of a U-shaped hanging metal fitting 23 is fixed to the upper part of the support metal fitting 17, that is, an upper surface of the upper horizontal reinforcing piece 15 with a bolt 25, and a U-shaped notch is formed in an upper horizontal piece 26 of the hanging metal fitting 23. The groove 27 is formed to form a horizontal support portion, and the hanging piece 23 of the hanging piece 23 is mounted on the horizontal piece 29 of the L-shaped first mounting piece 28 fixed to the vertical surface A ₁ of the upper edge side body A via the vibration-proof rubber 30. The upper horizontal piece 26 is connected by a bolt 31, and the vertical plate 33 of the supporting metal fitting 17 is attached to the vertical piece 33 of the L-shaped second mounting fitting 32 fixed to the opening edge A ₂ of the upper edge side body A via the antivibration rubber 34. 14 is a bolt
The support fittings 17 are connected to each other at 35 and are attached to the upper edge side body A in a vibration-proof manner.

[Action]

The vertical mechanical vibrations acting on the engine case 1 are absorbed by the vibration isolating rubber 30, and the lateral mechanical vibrations are absorbed by the vibration isolating rubber 34 and are not transmitted to the upper edge side body A.

Further, since the support portion of the hanging metal fitting 23 attached to the upper part of the engine case 1 is placed on the vibration isolating rubber 30, no shearing force is applied to the vibration isolating rubber 30.

(Other Embodiments) As shown in FIG. 4, the hanging bracket 23 is directly bolted to the upper lateral plate 10 of the engine case 1 and the second mounting bracket 32 is used.
The vertical plate 33 of the engine case 1 through the anti-vibration rubber 34

The engine case 1 in FIGS. 3 and 4 is made of aluminum or aluminum alloy.

[Effect of device]

The mechanical vibration in the vertical direction of the engine case 1 is absorbed by the anti-vibration rubber 30 provided upward on the first mounting bracket 28 attached to the upper edge side body A of the building opening, and the mechanical vibration in the lateral direction is absorbed on the building opening. The second support fitting 32 attached to the frame body A is absorbed by the anti-vibration rubber 34 provided sideways, and the horizontal support portion of the suspension fitting 23 provided on the upper part of the engine case 1 is attached to the anti-vibration rubber 30. Since it is placed and connected, its anti-vibration rubber 30
Since no shearing force is applied to the engine case 1, the engine case 1 can be stably attached to the upper edge side body of the building opening without rattling, and can be attached in a vibration-proof manner.

In order to mount the engine case 1 on the upper edge side body A of the building opening in a vibration-proof manner, the engine case 1 and the first,
Only by interposing the anti-vibration rubber between the second both mounting brackets 28, 32, this installation work is simple, and the anti-vibration rubber itself can be of a simple shape, so the cost can be reduced. For example, the engine case attachment structure is useful in the case of an automatic opening / closing door that is directly attached to the upper edge side body of the entrance opening of a building such as a factory or a warehouse.
