The invention relates to an open-close mechanism which can be applied on the doors, windows of the places like public hospital, cafe, pharmacy, building entrance, doors in public and private areas, which can be also used in all door and window systems that can be opened circularly with hinge group in automotive, white goods, furniture, housing sectors, and in addition it is possible to open the doors automatically without contact, taking into account the course of the epidemic and possible risks due to the epidemic caused by other contaminations such as corona virus (covid 19).

The invention especially relates to an open-close mechanism having the functionality that the power gained by the linear motion force and it converts this power into circular motion with the help of the coordinate finder tool, although it applies force from the closest point to the hinge point of the door or window, it provides easy movement to the door/window leaf without the need for high torque, unlike existing systems, it has an ergonomic structure by positioning it at a point close to the hinge point.

Prior Art

In current applications, doors can be opened manually, as well as electrically and mechanically, with drive systems. In the previous methods, the opening and closing process is applied to the door, which exhibits a circular motion on the door by electrical and mechanical drive method, again by giving a circular motion.

The disadvantages of existing door open-close systems are explained below. Due to the circular movement, the power requirement of the drive unit increases. In the drive units used in existing systems, when an opposite force is applied in the direction of the rotation axis of the door or vice versa, there is a risk of damaging the drive units as well as damaging the safety of life and property. This situation also constitutes a violation of occupational health and safety rules. For example, it makes it impossible to open the door or window manually in the event of a fire. Although unbraked transmission systems are used in existing systems, locking and breaking of the gearbox in cases where the door needs to be opened manually in case of fire, earthquake and similar situations, and consequently the door not opening, poses a great risk in terms of life and property safety. The electrical and mechanical structures used for opening and closing the doors, are not ergonomic (dimensional, weight and installation, etc.), and they reduce accessibility due to their high cost.

In the patent research, no patent that discloses the open-close mechanism that is the subject of the invention and has a similar operating principle has not been found. However, some patents made in the same technical field are referred to below.

The patent with the application number 2016/04634, registered in the registry of the Turkish Patent and Trademark Office, describes a mechanism that operates with traditional circular motion. However, the relevant mechanism does not include converting the linear motion to circular motion with a coordinate finder tool. The movement given to the door occurs in a circular manner.

European Patent No. EP2778333B1 relates to a device for detecting obstacles in front of a motorized door. It is not similar in purpose and structure with our invention. As a result, the existence of the above problems and the insufficiency of existing solutions made it necessary to improve the door/window opening and closing mechanisms.

Object of the Invention

The main object of the invention is; contrary to existing systems, the circular motion applied to the door is given by applying a linear force, not a circular force, and to develop an opening-closing mechanism that allows an extraordinary power gain for opening and closing the doors.

Another object of the invention is to reduce the size of the mechanism and find an application place at the point close to the hinge thanks to the power gain provided by the force made with a linear movement.

Another object of the invention is to eliminate the situation of preventing the manual opening of the door due to the inseparable integrity of the connection between the door moving part and the drive unit in existing mechanisms, by presenting a design that can be separated with reverse strength associated with the pin mechanism on the door moving leaf, and in case of emergency (power cut, battery failure, etc.) allowing the door to be opened manually.

To achieve the above objectives; the open-close mechanism has been developed which has a function that turns it into action with the help of the coordinate finding tool, wherein although the door or window applies force from the closest point to the hinge point, it enables the door/window to move easily without the need for high torque, has an ergonomic structure by positioning it at a point close to the hinge point, unlike existing systems, the power gained by the linear movement force and converts this power to circular motion Explanation of the Figures

Detailed Description of the Invention

The invention relates to an open-close mechanism (1) having the functionality that the power gained by the linear motion force and it converts this power into circular motion with the help of the coordinate finding tool (1.7), although it applies force from the closest point to the hinge (C) point of the door or window, it provides easy movement to the door/window leaf (B) without the need for high torque, unlike existing systems, it has an ergonomic structure by positioning it at a point close to the hinge (C) point.

A general perspective view showing the door/window leaf (B) in the closed position with respect to the frame/wall (A) is given in Figure 1. A general perspective view showing the door/window leaf (B) in half open (intermediate position) with respect to the frame/wall (A) is given in Figure 2. A general perspective view showing the door/window leaf (B) in the open position (90 degrees opened) with respect to the frame/wall (A) is given in Figure 3.

In Figure 4, a perspective view of the inventive open-close mechanism (1) that enables the door/window leaf (B) to make circular movement and open and close by means of hinges (C) relative to the fixed frame/wall (A) is given. In Figure 5, the exploded perspective view of the inventive open-close mechanism (1) is given.

The open-close mechanism (1) comprises a fixed plate (1.1) fixedly mounted on the fixed frame/wall (A). A linear movement mechanism (1.2) is positioned on the fixed plate (1.1). A rack gear mechanism is preferably used as the linear movement mechanism (1.2). However, alternatively, different types of movement mechanisms can be used. The linear movement mechanism (1.2) consists of a rack gear (1.2.1) and a pinion gear (1.2.2).

A linear motion mechanism (1.3) is positioned on the fixed plate (1.1) at the lower part of the linear movement mechanism (1.2). The linear motion mechanism (1.3) preferably consists of a linear rail (1.3.1) and a carriage (1.3.2) that can move on the linear rail (1.3.1). However, alternatively, different types of linear motion mechanisms can be used.

In the open-close mechanism (1), the driving power is provided by a drive unit (1.4). The drive unit (1.4) is preferably an electric motor. Alternatively, pneumatic, hydraulic, electric or manually driven drive units can be used. A reducer (1.5) is used on the drive unit (1.4) that changes the torque ratio of the rotational movement by means of gears. In addition, a control unit (1.6) is used to examine and manage the behavior of the drive unit (1.4).

The drive unit (1.4) is preferably fixed on a coordinate finding tool (1.7). The coordinate finding tool (1.7) is also fixed on the carriage (1.3.2) with connection elements (1.10) wherein said carriage (1.3.2) can move linearly on the linear rail (1.3.1). The drive unit (1.4) rotates the pinion gear (1.2.2) to which it is connected, enabling the pinion gear (1.2.2) to move on the rack gear (1.2.1). Thus, the drive unit (1.4) can move forth and back (x-y) along the linear rail (1.3.1) together with the coordinate finding tool (1.7).

An inclined channel (1.7.1) is formed on the coordinate finding tool (1.7), preferably resembling an elbow form. The inclined channel (1.7.1) is in connection with a pin (1.8) fixed on the movable door/window leaf (B) by a fixing means (1.9). While the movable door/window leaf (B) comes from the closed position to the fully open position, the pin (1.8) moves along the inclined channel (1.7.1). As seen in Figure 4 and Figure 6, when the coordinate finding tool (1.7) moves linearly in the y direction, the door/window leaf (B) starts to open by moving in a circular motion. When the coordinate finding tool (1.7) stops its movement in the y direction, the door/window leaf (B) comes to a fully open position. The degree of opening is preferably 90 degrees. However, the opening degree can be adjusted to greater than 90 degrees depending on the need.

The linear movement distance made by the coordinate finding tool (1.7) on the linear rail (1.3.1) is equal to the travel distance made by the pin (1.8) in the inclined channel (1.7.1).

A start unit (1.11) represented in Figure 6 can be used to open and close the door/window leaf (B). Start unit (1.11) may be a hand sensor, button, fingerprint system, face recognition system, foot pedal etc. The start unit (1.11) sends the trigger it receives to the drive unit (1.4) and initiates the movement.

As it seen in Figure 7, the symmetrical coordinate finding tools (1.7) can be used depending on whether the hinges (C) are on the right or left side of the door/window leaf (B), namely, depending on the door opening direction.

The invention relates to a linear driven fixed or mechanical impact controlled door open-close mechanism (1) that enables doors with hinge (C) group and the like to open-close and lock without contact by creating a circular angle different from zero that can be controlled by an electrical or manual movement.

The open-close mechanism (1) is located at the point close to the hinge (C) point of doors with circular hinge group and the like. The drive to be applied to the hinge (C) group on the body at an angle of 90 degrees by means of a fixed or mechanically impact controlled pin (1.8), by means of an electrical motor or a fixed or mechanical impact controlled pin (1.8) of a shaft to which manual linear movement will be applied in forward and backward directions. It is made possible by following the coordinates that do not change in the specified circle. If the system is driven electrically by a motor, it drives the mechanism where the motor gives a forward motion through the clockwise rotating motor shaft in order to perform the door opening operation. The door, on which a thrust force is applied, moves in the opening direction by following the unchanging coordinates whose circular radius is determined and it is allowed to open at the desired angle.

The mechanism driven forward by means of the drive element controlled by the drive unit (1.4) control unit (1.6) is stopped by means of a switch or encoder and waited for the specified time, then the drive element activates to move in the opposite direction and retracts the mechanism. In the meantime, the door takes the fixed or mechanical impact controlled pin (1.8) from the existing coordinates and brings it to the specified coordinates in the closing direction.

It completes the process with the encoder or end switch. Since the mechanical impact controlled pin (1.8) on the door moves by holding on to the existing mechanism, if the reverse force is applied by the user or an obstacle to be encountered while the engine is opening or closing, it will be defeated by the applied reverse force and manual control will be achieved as a result of the escape from the relevant mechanism.

The open-close mechanism (1) having the functionality that the power gained by the linear motion force and it converts this power into circular motion with the help of the coordinate finding tool (1.7), although it applies force from the closest point to the hinge (C) point of the door or window, it provides easy movement to the door/window leaf (B) without the need for high torque, unlike existing systems, it has an ergonomic structure by positioning it at a point close to the hinge (C) point.
