Description

[Detailed Description of the Invention] This invention relates to a mounting member that allows an engine unit of an automatic door opening/closing device to be easily and accurately mounted to a door opening of a building.

Conventionally, when installing an engine unit for an automatic door opening/closing device consisting of a motor, gearbox, control section, etc., the engine unit is first installed inside an engine case that has a roughly U-shaped cross section.
Plate-shaped coupling fittings are attached to both ends of this engine case so as to close these side ends, and then this engine case is stored in the door opening, which is formed into a substantially U-shaped cross section. This is accomplished by screwing coupling fittings fixed to the engine case to vertical members on both sides of the door opening. Therefore, the conventional method of installing the engine unit of an automatic door opening/closing device is compact and has a good appearance by making use of the blind opening for the door. No load is applied, so there is no need to create a particularly strong structure for the blinds.

By the way, the dimensions of entrances to buildings vary slightly depending on each entrance, and if the dimensional difference between the length of the engine case and the length between vertical members differs from the planned dimension, in other words, the difference between the design value and the actual construction There may be a dimensional error between the values and the actual mounting dimensions, which may require correction of the mounting dimensions during actual mounting work. In this case, in the above-mentioned conventional technology, the mounting dimensions are corrected by inserting the required number of mounting side plates having the same shape and dimensions as the joining fittings between the joining fittings attached to the engine case and the vertical members. . In practice, this is accomplished by fixing the required number of mounting side plates to the vertical members, and fixing the coupling fittings attached to the engine case to these mounting side plates. Therefore, when the dimensional error is large,
It is necessary to increase the number of mounting side plates, which increases the weight of the parts, and also requires long mounting screws. In addition, since the dimensions are adjusted by increasing or decreasing the number (thickness) of the mounting side plates, it is not possible to make continuous adjustments, and therefore it is not possible to adjust dimensions less than the thickness of one mounting side plate. There are also drawbacks. Furthermore, in the above conventional technology, when fixing the coupling fitting to the vertical member or the mounting side plate, a tool such as a screwdriver is placed inside the engine case and placed approximately parallel to the longitudinal direction of the engine case. There is also a disadvantage in terms of operation that the operation is very difficult.

This idea was made in view of the above circumstances,
To provide an engine unit mounting member for an automatic door opening/closing device, which allows correction of dimensional errors during actual construction to be easily and accurately performed without increasing costs, and improves workability. The purpose is to

This invention will be explained below with reference to the drawings. The figure shows one embodiment of this invention. As shown in the figure, the engine unit mounting member of the automatic door opening/closing device according to this invention is attached to an engine case 1 that houses the engine unit, and to both sides of the door opening. The engine case 1 is comprised of a fixture 3 that is fixed to the vertical member 2, and a connecting fixture 4 that connects and fixes the fixture 3 and the engine case 1.

The engine case 1 has a substantially U-shaped cross section, and houses therein an engine unit (not shown) consisting of a motor, gearbox, control section, etc., and has a rail-shaped edge at the front end of its lower part. This is a member that plays the role of slidably placing the door roller of the door on 1a, and is designed to be housed and fixed in a blind 5 having a substantially U-shaped cross section.

The fixing fitting 3 is formed by cutting a plate material and bending it into a substantially L shape, and its height is set to be the same as the height of the engine case 1. This fixing metal fitting 3 is attached to the inner surface 2a of the vertical member 2.
a wide fixed part (other side) 3a that is fixed in contact with the
A connecting part (one side) 3b located perpendicularly to one end of this fixed part 3a, and a mounting part 3 located perpendicularly to the inside of the upper and lower ends of this connecting part 3b.
c, 3c. The above fixed part 3a
A large diameter elongated hole 6, 6 is bored in the center of the engine unit, through which an electric wire for supplying electric power to the motor, control section, etc. of the engine unit is inserted, and on both sides of these elongated holes 6, 6, Long hole (long hole for fixing vertical member) 7 for attaching this fixing metal fitting 3 to the above-mentioned vertical member 2
Three a and three 7b are bored each. Further, bolts (bolt members) 8, 8 are screwed into the upper and lower parts of the connecting portion 3b so as to project inward.

The connecting fitting 4 is formed by pressing a plate material, and ribs 4a, 4a are formed on the upper and lower parts of the connecting fitting 4. One end (tip) of these ribs 4a, 4a is provided with a long hole (for connecting). long hole) 10,
10 are drilled. Further, a plurality of screw holes 11 are bored in the other end of the connecting fitting 4, so that it can be screwed to both ends of the engine case 1.

Note that in the above configuration, each long hole 6, 7a, 7
b, 10 are bored so that their longitudinal directions are horizontal when each member is assembled.

Next, a method of assembling the engine unit mounting member having the above structure will be explained. First, a screw receiving plate 12 having three screw holes 12a is screwed to the back surface of the vertical member 2 at a predetermined vertical position in advance. Then, attach the fixing part 3a of the fixing fitting 3 to the inner surface 2 of the vertical member 2.
a, insert the screws 13... into each elongated hole 7a or 7b, and then insert the screw holes 12a... of the receiving plate 12 into the screw holes 12a...
The fixing fitting 3 is fixed to the vertical member 2 by tightening the screws 13. At this time, the horizontal position of the fixture 3 relative to the vertical member 2 can be adjusted using the elongated hole 7a or 7b. Whether to use the long holes 7a or 7b for screwing is determined depending on the shape and dimensions of the vertical member 2. In the above configuration, holes for passing the screws 13 are formed in portions of the vertical member 2 corresponding to the screw holes 12a of the receiving plate 12, and electric wires are placed near these holes. A large diameter hole is drilled through it.

After fixing the fixing fittings 3, 3 to the vertical members 2, 2 on both sides as described above, insert a blind 5 between the vertical members 2, 2 so that the fixing fittings 3, 3 are covered by the blind 5. A hole is drilled at a predetermined position on the upper and lower surfaces of the blind 5, a screw hole 9 is drilled in the mounting portion 3c of the fixing fitting 3 to match the hole, and the screw 14 is screwed in. is connected to the fixture 3. Furthermore, at this time,
When a gap occurs between the attachment part 3c of the fixture 3 and the upper and lower surfaces of the blind 5, plate-shaped gap members 15 and 16 are interposed as shown in the figure.

On the other hand, the connecting fittings 4 are fixed to both longitudinal ends of the engine case 1 containing the engine unit with screws 17. engine case 1
After fixing the connecting fittings 4, 4 on both sides of the engine case 1, place the engine case 1 in the opening 5 and screw it into each elongated hole 10 of the connecting fittings 4, 4 and the connecting part 3b of the fixing fitting 3. Fit the bolts 8, 8. After that, screw nuts onto the bolts 8, 8, respectively, and attach the fixing fittings 3, 3 and the engine case 1.
Connect and fix. At this time, since the bolts 8, 8 protrude perpendicularly to the opening surface of the door, a sufficient working space can be secured, and the installation and fixing work of screwing and tightening the nuts is very easy to perform. At this time, even if the engine case 1 is cut to the required installation dimensions (planned dimensions), the engine case 1 and each of the fixing fittings 3, 3 do not come into contact as planned due to the installation error of the door opening. Even if there is a slight separation between the fixing bracket 3 and the connecting bracket 4,
Since the connection is made through the elongated holes 10, 10, errors can be corrected using the elongated holes 10, 10, and the fixing work will not be hindered.

As described above, the engine case 1 is attached to the vertical members 2, 2 by the fixing fittings 3, 3 and the connecting fittings 4, 4.
After fixing the engine case 1 to the blind 5 with the screws 18 and 19, the installation work is completed. The screws 18 and 19 are fixed to the nozzle 5 in order to prevent relative movement between the nozzle 5 and the engine case 1, thereby eliminating looseness between the nozzle 5 and the engine case 1. can.

As explained above, according to the engine unit mounting member of the automatic door opening/closing device according to this invention,
The following excellent advantages can be obtained.

() Since no new intervening member is required to correct dimensional errors when installing the engine unit, the weight of the mounting member does not increase even when dimensional errors are large.
