Description

  The present invention mainly relates to automatic opening / closing of home windows and doors.

2. Description of the Related Art Conventionally, a technique related to an automatic opening / closing device such as an office building window, a door, or a window glass of an automobile is well known.
On the other hand, the opening and closing of home windows and doors is mostly manual, and in rare cases, automatic window opening and closing devices for office buildings and the like are installed.

However, in general households, installing an automatic device for opening and closing windows, doors, etc. is disadvantageous in terms of facilities and cost.
Therefore, without installing expensive installation work or equipment on home windows, doors, etc., simply opening and closing the windows by setting a unit with a sensor on the window frame, promoting indoor ventilation and adapting to the environment It was solved by creating a low-cost automatic window opening and closing unit.

  The present invention is driven through a drive unit including a DC motor activated by a temperature sensor, a humidity sensor, a timer, or the like and a gear rotated by the motor inside a synthetic resin casing. This problem has been solved by storing a horizontal movement part composed of an operating belt roller and providing an engagement member at the tip of the horizontal movement member.

As described above, in the automatic window opening / closing unit of the present invention, a belt roller driven by a temperature sensor or a DC motor activated by a timer and a gear fitted to the motor drive shaft inside a synthetic resin casing. Since the unit body is installed in a household window frame or door, etc. without wiring equipment from an AC power supply, the engaging member provided at the tip of the operating belt roller is locked to the window frame. It can be set by simple work that only engages with the member, and at that time, the opening / closing stroke of the window can be appropriately set according to the size of the window frame, and the amount of outside air taken in can be adjusted. is there.
In addition, the sensor unit has a built-in temperature sensor, humidity sensor, human body sensor, noise sensor, and timer, so various sensors can be selected according to the home environment, and health management for the elderly, sick and infants, etc. Contribute to.
Furthermore, since the unit is compactly formed, there is an effect that it can be stored in a closet or a storage room when not in use depending on the season.

  The casing body is composed of upper and lower casings and is integrally molded with a synthetic resin. The shape of the casing body is substantially convex when viewed from the front, and the inside is hollow. A DC motor having a dry battery that can be charged as a drive source is provided at the upper part of the casing, and a gear made of synthetic resin is fitted to the tip of the rotating shaft of the motor. As the DC motor, a motor having a large torque that can respond to the gentle rotation of the gear is adopted so as to withstand the opening / closing operation of the window. In the vicinity of the motor, when the operating belt roller is operated in a state where the window is locked, an overcurrent detecting component capable of automatically returning that effectively functions to prevent the motor from being burned is disposed.

  In addition, a power switch for starting and operating the motor, a switch for pushing / retracting the driving belt roller, a switch for switching to maintenance or normal operation, and the like are disposed on one side wall of the upper casing, and a battery pack or an AC adapter. A power supply jack for connection and a sensor port for inserting a cable of a sensor unit incorporating a temperature sensor, a humidity sensor, a human body sensor, a timer, or the like are provided.

On the other hand, a rubber or synthetic resin operating belt roller with concave and convex teeth meshing with the gear teeth at the lower part of the casing has a pull-back limit lever at the top of the tip, an extrusion limit lever at the top of the rear end, and a tip at the tip. Locking tools such as detachable hooks that engage with the moving window frame are provided and are integrally molded.
Further, a pullback limit switch and a push limit switch for controlling the moving range of the operating belt roller are provided in contact with the pull limit lever and the push limit lever near the upper and lower joints of the casing, respectively.

A fixed pedestal made of metal or synthetic resin and an L-shaped working belt pedestal movable to the fixed pedestal are placed on the bottom of the casing, and the working belt roller is fixed to the L-shaped inner side wall by a fixed adhesive sheet, Polymerized and laminated in parallel with an adhesive or the like.
Further, a fixed adhesive sheet is attached to the bottom rear surface of the lower part of the casing, and the casing is fixed to an appropriate position of a window frame such as a window glass door.

  In such a configuration, maintenance and normal switches are used to perform presetting, and the motor and gears are driven by the operation of the temperature or humidity sensor or the start of a timer according to changes in room temperature or humidity, and are combined with the window frame. The driven belt roller is pulled back into the casing and the window is opened. On the other hand, the window is normally automatically closed by operating a switch according to the indoor environment.

Embodiments will be described below with reference to the drawings.
1 to 4 show an embodiment in which the basic configuration of the present invention is applied to a sliding door window.
Reference numeral 1 denotes a casing having a convex shape when viewed from the front, and is integrally formed of a synthetic resin.
