  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste. In this specification, the front side in the direction from the indoor side to the outdoor side (see arrow F in the figure) is the front, the rear is the rear, and the left and right are the front.

  The opening / closing window 1 shown in FIG. 1 and FIG. 2 can open the shoji (opening / closing body) 4 attached to the window frame (fixed side member) 3 to the outdoor side by an electric opening / closing device 2, and slides sideways. A window is shown as an example.

  The window frame 3 is composed of an upper frame 3U and a lower frame 3L, and left and right vertical frames 3S and 3S. The shoji 4 is composed of an upper frame 4U and a lower frame 4L, left and right vertical frames 4S and 4S, and two front and rear glasses 4G and 4G. Since the shoji 4 is supported by the window frame 3 so that it can be opened and closed by left and right stays 5 and 5 that are configured and attached between the left and right vertical frames 3S and 3S and the left and right vertical rods 4S and 4S. The shoji 4 incorporated in 3 can be opened to the front side (outdoor).

The opening / closing device 2 includes an opening / closing mechanism 11 that opens and closes the shoji 4, an electric motor 12 that drives the opening / closing mechanism 11, and the like.
The opening / closing mechanism 11 is supported by a base body 24 attached to the lower frame 3L. The worm wheel 10 has an operation shaft 8 at the left end and extends in the left-right direction, meshes with the worm 9, and swings around the vertical axis A. The worm wheel 10 and the base end are integrated into a first swing arm 22 extending in the front horizontal plane, and the first swing arm 22 is pivotally connected to the first swing arm 22 by a pin 27 having a vertical axis. A pin 28 which is a vertical shaft attached to the other end (outside end portion) is inserted into a long hole 6A extending in the left-right direction of the window frame side metal fitting 6 and attached to the other end (outside end portion). Comprises a second swing arm 23 or the like inserted into a long hole 7A extending in the left-right direction of the shoji side metal fitting 7, and the shoji 4 can be opened and closed by rotating (forward or reverse) the operation shaft 8. .

  The opening / closing mechanism 11 can obtain a large operating force by a small torque that rotates the operating shaft 8 and can utilize a characteristic that the worm cannot be turned from the worm wheel 10 when the shoji 4 is opened. 4 is configured by worm gears 9 and 10 that can be held in an open state, but is not limited thereto, and any device that can open and close the shoji 4 by the driving force of the electric motor 12 is used. The shoji 4 may be opened and closed.

  In the opening / closing mechanism 11 (excluding the second swing arm) shown in FIGS. 3 and 4, the output shaft 26 of the electric motor 12 and the speed reducer 25 supported by the base body 24 moves the gears 18 and 19 in the gear case 30. The operation shaft 8 is rotated via the worm wheel 10 and thereby the worm wheel 10 is rotated via the worm 9 fixed to the operation shaft 8, so that the control panel can be operated by operating a remote control operation unit (not shown). The shoji 4 can be opened and closed by driving the electric motor 12 through 31.

A reduction gear 25 is attached to the electric motor 12, and the buffer sheet 13 is wound around substantially the entire outer circumference of these motors. In addition, the electric motor 12 and the speed reducer 25 are attached to the base body 24 by a rubber blind nut 16 and a bolt 17 with a bracket 15 fixed on the output shaft side through a buffer member 14. For this reason, the electric motor 12 and the speed reducer 25 do not contact the base body 24, and it is possible to suppress the vibration from being transmitted to the base body 24. Further, since the rubber blind nut 16 is in contact with the bracket 15 only in the rubber portion in this attached state, vibration transmitted from the electric motor 12 to the bracket 15 is transmitted from the bracket 15 to the base body 24 via the screw member. Can be suppressed.
Furthermore, the noise generated by the electric motor 12 and the speed reducer 25 can also be prevented from leaking to the outside by the buffer sheet 13. Further, even if the electric motor 12 collides with the base body 24 and the like due to vibration during the operation of the electric motor 12, the collision sound can be suppressed and the impact on each member due to the collision can be absorbed.
Here, like the electric motor 12, the speed reducer 25 is covered with the buffer sheet 13 and does not transmit the vibration to the base body 24. The noise and vibration of the speed reducer 25 are also soundproof and vibration-proof. It is supposed to be effective.

  The buffer sheet 13 and the buffer member 14 are rubber bodies made of polyurethane as a raw material, and the front surface and the back surface have adhesiveness. Therefore, the buffer sheet 13 and the buffer member 14 also have an effect of preventing the electric motor 12 from being displaced. Even if it does not exist, it should just have the effect | action which absorbs a vibration.

  Further, for fixing the bracket 15 and the base 24, three sets of rubber blind nuts 16 and screw members of bolts 17 are used. As a result, the electric motor 12 in the circumferential direction around the output shaft 26 and the base 24 of the bracket 15 against the reaction force transmitted from the shoji side to the output shaft 26 of the speed reducer 25 via the worm gears 9, 10, etc. The appropriate position of the electric motor 12 can be maintained without being displaced in the circumferential direction or the like with the screw member for attachment (using the rubber blind nut 16) as an axis.

  The fixing of the bracket 15 and the base 24 is not limited to the three rubber blind nuts 16 and the bolts 17 as long as the appropriate position of the electric motor 12 can be maintained. Fixing with the rubber blind nut 16 and the bolt 17 as described above, or fixing by screwing a cushioning sheet or the like between the nut and the fixed member and between the head of the bolt and the fixed member. Etc.

FIG. 5 shows an exploded perspective view of main components of the opening / closing mechanism 11 (excluding the second swing arm).
The electric motor 12 and the speed reducer 25 are wound with a buffer sheet 13 having substantially the same width as this, and the base mounting portion of the bracket 15 is positioned in a portion not covered by the buffer sheet 13 and decelerated in the hole of the motor mounting portion. The output shaft 26 of the machine 25 is inserted, and the output shaft side is fixed to the speed reducer 25 with screws.
The bracket 15 is attached to the base body 24 by a rubber blind nut 16 via a buffer member 14. That is, the buffer member 14 and the rubber blind nut 16 can fix the position of the electric motor 12 and the speed reducer 25 with respect to the base body 24 without transmitting vibration to the base body 24.

  On the other hand, the gear 18 is attached to the output shaft 26 of the speed reducer 25 so as not to rotate. The gear 18 meshes with a gear 19 that is non-rotatably attached to the operation shaft 8. A worm 9 is formed substantially at the center of the operation shaft 8, and a boss 20 and a spring 21 are attached to both ends thereof, and the operation shaft 8 is fixed to the base 24 so as to be rotatable. The worm 9 is configured so that the worm wheel 10 of the first swing arm 22 rotatably attached to the base body 24 is engaged, and the shoji 4 is opened and closed by driving the electric motor 12.

  With the above-described configuration, the opening / closing device 2 of the present embodiment has an operation sound before the shoji attachment of 43 dB (decibel) and an operation sound after the shoji installation of 48 to 53 dB. Compared with the later 70 dB), the operating noise can be remarkably reduced.

  In the above description, the case where the opening / closing window 1 is a side sliding window is shown, but the opening / closing window 1 may be a vertical sliding window, a louver window, an awning window, a skylight, or the like. In addition to electrically opening / closing the opening / closing body (shoji) of the opening / closing window 1, the opening / closing body such as a lid or a door of the storage can be used as an opening / closing device for electrically opening / closing.
