Automatic opening and closing device for window with improved operating stability

The present invention relates to an automatic opening and closing device for a window having an improved operating stability, and more particularly to the opening and closing of the window installed on the window frame by moving the operation unit by the drive of the drive unit, the connection state between the drive unit and the operation unit In the non-driving state of the driving unit by the clutch unit to control, the connection state between the driving unit and the operating unit is dismantled to open and close the automatic opening and closing device for the window having the improved operational stability to enable the opening and closing of the window by manual operation. It is about.

In general, the window is opened and closed through manual operation, and recently, such as smoke exhaust window is installed an automatic opening and closing device to automatically close the sliding or pulling the window installed on the window frame by converting the rotational force of the electric motor into a straight transfer.

By the way, the conventional automatic opening and closing device for a window has a state in which the electric motor for generating rotational force and the electric motor for opening and closing the chain rope are always connected, so that the window provided with the automatic opening and closing device is applied to the braking resistance of the stationary motor. There is a problem that the opening and closing of the window through the manual operation is impossible.

That is, when a power failure or abnormality of the stationary motor is generated and generation of the rotational force of the stationary motor is impossible, the window cannot be opened and closed arbitrarily.

Therefore, in the field, there is a demand for the development and dissemination of a new type of automatic opening and closing device for windows capable of opening and closing windows by electric and manual operation.

On the other hand, the inventors advance and retract the first clutch member, which is fixed to the drive shaft of the drive unit, and the second clutch member, which is installed in the retraction structure on the connecting shaft of the operation unit through the Republic of Korea Patent Application No. A clutch part including a solenoid for controlling the connection state between the first clutch member and the second clutch member is provided between the driving portion and the driven portion, and the manual opening and closing function of the window, which has been difficult to achieve in the past, by connecting or dismantling these clutch members, is provided. I have it.

However, as shown in FIG. 6, a jam phenomenon in which they are fixed by local interference is intermittently between the connecting shaft 31 manufactured in a square shape and the second clutch member 42 'provided in the retracting structure on the connecting shaft. When this jam phenomenon occurs, even if the second clutch member is provided with a spring force, it is difficult to achieve a stable retraction for disengagement from the first clutch member, and this jam phenomenon causes the first clutch member and the second clutch. If the clutch member is not disassembled, a problem arises in that the manual opening and closing function of the window cannot be implemented.

Of course, if the strength of the spring disposed between the first clutch member and the second clutch member is increased, this jam phenomenon can be eliminated. However, if the strength of the spring is increased, the sole is configured to compress the spring to advance the second clutch member. The problem of increasing the capacity of the Lloyd is inevitably generated, and the increase of the solenoid capacity is required to increase the additional cost, volume, and current consumption, so that the change of the spring is not a realistic solution.

In addition, the conventional automatic opening and closing device for a window is a safety accident since the driving unit does not stop and continuously closes the window even when a human arm is caught between the window and the window frame during the closing process of the window by driving the stationary motor. May have occurred.

An object of the present invention devised by the above-mentioned request is that the electric opening and closing and manual opening and closing of the window are alternatively implemented according to the connection or dismantling of the clutch formed between the driving unit and the operating unit. It is to provide a window automatic opening and closing device to ensure the stability by disassembling the clutch for manual opening and closing of the window.

The above object is achieved by the following constitutions provided in the present invention.

Automatic opening and closing device for a window according to the present invention,

A driving unit for outputting rotational force through the power shaft; An operating unit for applying a rotational force output from the power shaft through a connecting shaft and advancing and connecting the connecting end through the rotating force to open and close a window; The first clutch member and the second clutch member are fixedly installed on one of the power shaft and the connecting shaft, the second clutch member provided in the retracting structure on the other shaft, and the second clutch member. A clutch unit including a solenoid for controlling a connection state of the clutch member; A control unit controlling driving of the driving unit and the clutch unit; And a main body forming their installation space,

On the opposing surface of the first clutch member and the second clutch member, a adherent groove for adhering the adherent protrusion and the adherent protrusion to adhere to the inner side wall of the adherent protrusion is formed to correspond to the inner side wall, and the outer wall of the adherent protrusion is adhered to. A dismantling block having a slanted inclined surface is formed between the inner walls of the attachment grooves, and the second clutch member connected to the first clutch member by the attachment to the inner walls of the attachment grooves has the disengagement block in the reverse rotation process of the power shaft. It is characterized in that it is configured to retreat by interference with the photographic oblique surface and to be disconnected from the first clutch member.

Preferably, the inner wall of the adhesion groove and the outer wall of the adhesion protrusion adhered to the attachment groove are configured to have an inclined bevel shape that gradually increases in width from the front end to the rear end, and is driven by driving of the solenoid. 2 If the power shaft rotates in one direction while the clutch member moves forward and the adhesion protrusion enters the attachment groove, the second clutch member moves forward in a state in which the second clutch member is adhered by interference between the inner wall of the attachment groove and the attachment protrusion outer wall of the inclined shape. It is configured to be connected in close contact with the first clutch member.

More preferably, the drive unit rotates the power shaft of the drive unit connected to the connecting shaft through the first clutch member and the second clutch member, which are tightly constrained through the attachment protrusion and the attachment groove in one direction to open and close the window, and then rotate in the reverse direction. Thus, the clutching state of the first clutch member and the second clutch member, which are tightly constrained through the adhesive protrusion and the adhesive groove, is released, while the second clutch member is retracted by interference with the inclined slope of the dismantling block.

In addition, a spring is disposed between the first clutch member and the second clutch member, and the retraction rod and the second clutch member of the solenoid have a force point connected to the retraction rod of the solenoid, an action point that is attached to the second clutch member, And a support point configured to support the force point and the action point in a pivoting structure.

As described above, in the present invention, the clutch unit is formed between the driving unit and the operating unit, so that the manual opening and closing of the window is possible by disassembling the driving unit and the operating unit by the clutch unit, and the slanted surface inclined to the adherent groove formed in the clutch unit. The disassembly block having a structure is arranged so that the second clutch member attached to the first clutch member is forcibly retracted by the interference with the inclined slope of the disassembly block.

In this configuration, the jam may occur intermittently between the second clutch member and the shaft, thereby eliminating the disassembly of the first clutch member and the second clutch member, thereby eliminating the problem of manual opening and closing of the window.

In the present invention, since the inclined slanted attachment grooves and the adhesion protrusions are formed between the first and second clutch members, respectively, and are engaged in a state in which they are adhered to each other during the rotation process, the continuous operation of the first clutch member and the second clutch member is performed. Since the process of continuously driving the solenoid is unnecessary to maintain the connection state, the life of the solenoid is extended by shortening the driving time of the solenoid, and the current consumption is reduced.

In addition, in the present invention, by forming a load measuring unit for measuring the load of the drive unit in the control unit, to prevent safety accidents such as pinching the arm between the window and the window frame, and also to elastically restrain the operation unit by the elastic stopping structure In addition, it is possible to prevent the window from being opened arbitrarily due to the change in the air pressure in the room caused by the operation of the air supply damper.

Opening and closing the 100, the opening and closing of the window through the chain rope 33 is a generalized technology.

However, in the present invention, as shown in FIGS. 2 and 3A, one or more position fixing grooves 34a are formed in the operation unit 30, and the stopping protrusions 11a of the elastic stopper 11 are formed in the position fixing grooves 34a. ), The driving of the operating unit 30 is elastically constrained.

Referring to the drawings, in the present embodiment, the position fixing grooves 34a are formed in the connecting end 34 connecting the window 100 and the chain rope 33 in the operating part 30, and the main body 10 An elastic stopper 11 for elastically fixing the transfer of the connecting end 34 by entering the stoppering protrusion 11a supported by the spring 11b into the position fixing groove 34a of the connecting end 34 at one point. ) Is placed.

Here, the spring 11b of the elastic stopper 11 is configured to support the rear end of the adjustment bolt 11d fastened to the case 11c, and according to the fastening amount of the adjustment bolt 11d of the stoppering protrusion 11a. The grip force is configured to be adjusted, and the change in the grip force of the stopping protrusion 11a is proportional to the elastic fixing force of the connecting end 34 and the window 100 fixed to the connecting end 34.

In this configuration, even when the power shaft 21 and the connecting shaft 31 are disassembled by the clutch unit 40 as described below, the operating unit 30 forms a state of being elastically constrained by the elastic stopper 11. Therefore, the phenomenon in which the window is randomly opened due to the change in the indoor air pressure due to the operation of the air supply damper (not shown) can be prevented.

On the other hand, the clutch 40 for setting the electric opening and closing of the window and the manual opening and closing of the window by connecting or dismantling the power shaft 21 and the connecting shaft 31, the power shaft 21 as shown in FIG. A first clutch member 41 fixed to one of the shafts and the connecting shaft 31, and a second clutch member 42 installed in the restraint structure; And a solenoid 43 for advancing and retracting the second clutch member 42 to control the connection state between the first clutch member 41 and the second clutch member 42.

Connected.

Therefore, when the advancing rod 43a of the solenoid 43 is advanced, the second clutch member 42 is advanced along the connecting shaft 31 to be in close contact with the opposing surface of the first clutch member 41.

In addition, in the present embodiment, a pair of adherent grooves 41a are formed in the opposing surface of the first clutch member 41, and the adherent grooves 41a are formed on the opposing surface of the second clutch member 42. A pair of narrower attachment protrusions 42a are formed to correspond to each other, while a spring 45 is disposed between the first clutch member 41 and the second clutch member 42.

Therefore, the window automatic opening and closing device 1 is usually of the first clutch member 41 and the operating unit 30 fixed to the power shaft 21 of the drive unit 20 by the elastic force of the spring (45). Since the second clutch member 42 installed in the connecting shaft 31 in a retracted structure is separated from each other to form a disassembled state, the user can manually open and close the window 100 without rotational resistance caused by the connection with the driving unit 20. Do.

Then, when the controller 50 advances the retraction rod 43a of the solenoid 43, the second clutch member 42 connected to the retraction rod 43a of the solenoid 43 through the lever 44 is connected to the connecting shaft.

At this time, the outer walls 42a-a of each of the adhesion protrusions 42a formed on the second clutch member 42 are the first clutch member 41. The state adhered to the inner side wall 41a-a of each adhesion groove 41a formed in this is formed.

In this state, when the control unit 50 rotates the power shaft 21 of the drive unit 20 in the forward or reverse direction, the operating unit 30 is a rotation force applied from the power shaft 21 through the connecting shaft 31. By applying the chain rope 33 and the connecting end 34 to advance the electric opening and closing of the window 100, this action is similar to the applicant's prior application.

However, the control unit 50 rotates the power shaft 21 when a load greater than or equal to the reference value is measured during the closing process of the window 100 through the load measuring unit 51 measuring the load of the driving unit 20 through the amount of current applied. Stop or rotate in the reverse direction to stop the opening and closing of the window by electric.

Therefore, the automatic opening and closing device for a window according to the present embodiment solves the safety problem as the electric closing of the window is continuously implemented even in a state where an obstacle such as a human arm is sandwiched between the window frame and the window.

The disassembly block 41a-b is formed to protrude, and as shown in FIGS. 3B and 4A, 4B, and 4C, the first clutch member (A) is adhered to the inner wall 41a-a of the attachment groove 41a. The second clutch member 42 connected with 41 is retracted by the interference with the inclined slope of the disassembling blocks 41a-b during the reverse rotation of the power shaft 21, and is connected to the first clutch member 41. Is to be dismantled.

Accordingly, even if a jam occurs between the connecting shaft 31 of the operating section 30 and the second clutch member 42 provided in the connecting shaft 31 in a forward and backward structure, the second clutch member 42 is reversed. The connection state with the first clutch member 41 is forcibly retracted due to interference with the dismantling blocks 41a-b formed in the attachment groove 41a of the first clutch member 41 fixed to the rotating power shaft 21. Dismantled.

Thus, the automatic opening and closing device 1 for a window according to the present embodiment having the retracting structure of the second clutch member 42 through such dismantling blocks 41a-b is provided between the second clutch member 42 and the shaft. Even if jamming occurs intermittently, retraction of the second clutch member 42 and disassembly of the first clutch member 41 for switching the window to the manual opening and closing state are possible.

In addition, in the present invention, as shown in FIGS. 3B, 5A, 5B, and 5C, the inner wall 41a-of the attachment groove 41a formed in the first clutch member 41 and the second clutch member 42 is provided. The shape of a) and the outer walls 42a-a of the abutment protrusion 42a are improved so that the first clutch member 41 and the second clutch member 42 mutually operate even when the solenoid 43 is not continuously driven.
