Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cover mounting device for an engine case that houses a drive mechanism for opening and closing an automatic door.

Prior Art As shown in Japanese Utility Model Publication No. 53-4039, mounting brackets are fixed to a U-shaped main body and a cover, and the mounting brackets are connected to each other with screws inserted through elongated holes. A cover mounting device is known in which the cover is rotatably engaged and connected to the upper open end of the main body.

Problems to be Solved by the Invention With such a cover mounting device, the connecting length of the mounting brackets can be changed to allow the mounting brackets to be used when installing doors of different widths, and the cover can be rotated upward to attach to the main body. The drive mechanism can be easily maintained and inspected because it can be opened.

However, on the other hand, the mounting brackets attached to the main body side and the mounting brackets attached to the cover side have different shapes, increasing the number of parts, and the screws that secure the mounting brackets and the cover are visible from the outside, making it look unsightly. Moreover, the connecting part between the upper part of the cover and the upper open end of the main body becomes rattled due to vibration and generates noise.

Means and action for solving the problem One of the first and second mounting brackets has the same shape by fitting the locking piece of the cover into the upward recess formed at the upper opening end of the main body via vibration damping rubber. is fixed to the lower opening end of the main body with screws, and the other is fixed with screws that screw into the back plate inserted into the groove formed in the cover, and the screw holes and elongated holes of the first and second mounting brackets are By matching the screws and overlapping and connecting them, the first and second mounting brackets can be made into the same shape, and the screws are not visible from the outside, giving a better appearance.
Moreover, it is designed to prevent rattling due to vibration.

Embodiment The engine case 1 includes a main body 2 and a cover 3. The main body 2 is formed into a substantially U-shaped elongated member by a vertical plate 4 and upper and lower horizontal plates 5 and 6, and the upper horizontal plate 5 has an open end side. An upward recess 7 is formed in the longitudinal direction, the lower horizontal plate 6 is shorter than the upper horizontal plate 5, and a first mounting bracket 8 is fixed to the open end with screws 9.

The cover 3 has a plate shape, and a locking piece 1 is provided on the top of the cover 3.
0 is integrally formed downward through an overhanging piece 11, and a groove 12 is formed in the lower part, and the locking piece 1
0 is fitted into and engaged with the upward recess 7 via a vibration damping rubber 13 so as to be able to move up and down freely, and a second mounting bracket 14 is attached to the lower part with screws 15 and a back plate 16 inserted into the groove 12. At the same time, the first and second mounting fittings 8 and 14 are connected by screws.

The first and second mounting brackets 8 and 14 are mounted on mounting pieces 20.
The connecting piece 21 has a long L-shaped cross section, and the mounting piece 20 has a screw insertion hole 22, and the connecting piece 2
1 is formed with a screw hole 23 and a long hole 24 to have the same shape, and the mounting piece 20 of the first mounting bracket 8 is inserted into the screw 9 through a vibration damping material 25 at the lower open end of the main body 2.
screws 15 that are connected to each other and that the mounting piece 20 of the second mounting bracket 14 is screwed into the back plate 16 inserted into the concave groove 12.
is connected to the lower part of the cover 3 via the vibration damping material 26, and the connecting pieces 21 of both overlap and screw holes 2
3 and a long hole 24 are opposed to each other, and a screw 27 is screwed into the screw hole 23 from one of the long holes 24 for connection.

Since it is like this, the first and second mounting brackets 8, 1
4 can be made into the same shape, and the connecting length can be changed by the length of the elongated hole 24, so that it can be used for installing doors of different widths.

Furthermore, the screws 15 are not visible from the outside, resulting in a better appearance.

Further, since the locking piece 10 is fitted into the upward recess 7 via the vibration-absorbing rubber 13, there is no rattling due to vibration and no noise is generated.

Effects of the invention Since the connecting length of the first and second mounting brackets 8 and 14 can be changed by the length of the elongated hole 24, the first and second mounting brackets can be used in common even when installing doors of different widths.

Since the first and second mounting fittings 8 and 14 have the same shape, it is sufficient to manufacture the mounting fittings in one shape, thereby reducing manufacturing costs.

Since a vibration-absorbing rubber 13 is interposed between the upward concave portion 7 and the locking piece 10, which is the locking connection portion between the cover 3 and the main body 2, there is no rattling due to vibrations, so noise is reduced. Does not occur.
