Description

The present invention relates to an actuator device for moving an object such as a window or a door in a horizontal direction or a vertical direction.

The windows of buildings, such as ordinary houses, are opened and closed by sliding the glass doors of sliding windows or the glass doors of upper and lower windows by hand. The opening and closing operation is not limited to windows, but is also performed on entrances, indoor doors, and drawer cases of indoor chests of drawers. However, some windows and doors are heavy, and slippage becomes worse due to deterioration over time, making it difficult to open and close, which is a heavy burden especially for elderly people and the like. In addition, when a person receiving nursing care or rehabilitation at home or in a hospital wants to open a window to replace the air in the room, it is difficult to open and close the window by himself / herself. I had to do it with help.

Against this background, as a device for assisting the opening / closing operation of windows and doors, for example, a sliding door to which an opening / closing assisting force device is added (Patent Document 1) and a device to which a balance weight is added to assist opening / closing up and down (Patent Document 2). , A device that assists opening and closing by using power supplied from a solar cell panel (Patent Document 3) and the like have been proposed.

On the other hand, lifters and stair lifts are known as devices for lifting objects such as luggage and heavy objects upstairs in a three-dimensional warehouse of a building or a house.

The tape composite 20 is pulled out for a predetermined length against the spring force of the mainspring 13 (after being pulled out, the pulled-out state is locked by the lock mechanism attached to the mainspring 13), and is supported by the moving body support portion 30 at the tip. This is for moving the moving body horizontally or vertically, and a plurality of metal tape members 21 to 23 having a curved cross section (three in the illustrated example) are combined in a vertically stacked manner. ing. In each of the metal tape members 21 to 23, the middle metal tape member 22 offsets the tip rearward of the lower metal tape member 21 on the lower metal tape member 21 whose rear end is connected to the spring end of the spring spring 13. The upper metal tape member 23 is arranged on the middle metal tape member 22 with its tip offset to the rear of the middle metal tape member 22.

The tape composite 20 has a gutter-shaped cross section, and by using a plurality of metal tape members 21 to 23 stacked on top of each other, the length (distance) for ensuring uprightness and horizontality is greatly extended until buckling. A metal tape member with a tape width of 22 mm and a gutter-shaped cross section was used, and a moving body with a load of 100 g was placed on the tip of the metal tape member to support it horizontally and cantilevered. However, it was 1020 mm when two sheets were stacked, and 1350 mm when three sheets were stacked. Further, when a metal tape member having a tape width of 22 mm and a gutter-shaped cross section was used, a folded portion was provided at the tip thereof, the folded portion was folded back in a U shape, and a moving body having a load of 100 g was placed on the folded portion to support the seat vertically. The length until bending was 1000 mm in the case of one sheet, 1900 mm in the case of stacking two sheets, and 2000 mm in the case of stacking three sheets.

In these metal tape members 21 to 23, the middle metal tape member 22 and the upper metal tape member 23 are overlapped on the upper surface of the lower metal tape member 21 in a state where the lower metal tape member 21 is pulled out by the maximum amount.

Each of the delivery belts 41, 41 is wound between the pulleys 43, 43 integrated with the front and rear rotating shafts 42, 42, which are rotatably supported between the left and right bearings 44, 44 attached to the inner surface of the outer box 70. ing.

The delivery guide unit 40 is provided with a transmission gear (not shown) between the drive shaft of the motor 50 and the rotary shafts 42, 42, and the driving force in the forward / reverse direction from the motor 50 is applied to the rotary shafts 42, 42. With respect to the moving body supported by the moving body support portion 30A at the tip, the moving body is sent out for a predetermined length while applying a predetermined pushing output to the tape composite 20 to move the moving body in the horizontal or vertical direction. Further, by stopping the drive of the motor 50, the tape composite 20 delivered for a predetermined length can be locked to a predetermined length.

The motor 50 electrically drives the tape composite 20 against the spring force of the mainspring 13 inside the take-up portion 10 by turning on the switch, and is determined when the motor 50 is stopped by turning off the switch. The long-delivered tape composite 20 is locked. Further, when rewinding the tape composite 20 delivered for a predetermined length, the drive by the motor 50 is also used. The switch may be turned on and off with a remote remote controller.

The tip of the tape composite 20 is folded back in a U shape via the folded guide portion 60, and a box-shaped moving body support portion 30A is arranged so as to surround the tip folded portion 20A. The folded guide portion 60 has a pair of guide rollers 61, 61 that come into contact with the back surface of the tape complex 20 at a certain distance to fold the tip of the tape complex 20 in a U shape, whereby the end of the tape complex 20 is folded back. The tape composite 20 is held in a structure that does not easily buckle without twisting the folded-back portion 20A.

Of the tape composite 20, the folded end 21a of the outermost metal tape member 21 is fixed to the upper surface 70a of the outer box 70 by the fixing member 31. The folded ends 22a and 23a of the middle and innermost metal tape members 22 and 23 are free ends, so that the inner ring difference between the metal tape members 21 to 23 in the tip folded portion 20A is released.

The moving body support portion 30A is supported by the rotating shafts 62, 62 of the pair of guide rollers 61, 61, and the composite tape member 20 is fed by the feeding guide portion 40 and at the same time moves in the feeding direction. The moving body support portion 30A is, for example, a sliding door type glass door (sliding window) that slides left and right on a rail as a moving body that moves horizontally, and a door that is pivotally supported between upper and lower hinges and rotates freely. It is mounted and supported on a glass door (upper and lower windows) that slides up and down on the left and right crosspieces as a moving body that moves vertically at the upper end.
