As there are frequent cases of injuries caused by fingers becoming caught between the door frame and the door frame due to the rapid closing of the door, various devices to prevent fingers from being caught between the door and the door frame are being developed. The most common method is to use magnetic force by installing a magnet on a door or door frame, and various methods have been attempted to install elastic materials (e.g. rubber, springs, etc.) that can absorb shock.
However, this method does not achieve the intended buffering function after a long period of time due to the gradually weakening magnetic force and the characteristics of the rubber materials that undergo denaturation.
Furthermore, there is no method of providing a buffering function not only when opening the door but also when closing it.
The present invention is connected to rotate in conjunction with the rotational motion that occurs during the opening and closing operation of the door, and includes a groove 1 for seating the door frame connection part of the linker that is connected to interlock with the door frame of the door, and a locking groove for controlling disconnection from the door frame.

Description

Door open and closing energy controlling device}

The present invention relates to a control device for a swing door that increases and decreases the opening and closing operation speed.

In particular, the present invention relates to an adjustment device for preventing fingers from being caught when opening or opening a door and at the same time preventing collision with a door frame other than the door due to rapid opening or opening.

As there are frequent cases of injuries caused by fingers becoming caught between the door frame and the door frame due to the rapid closing of the door, various devices to prevent fingers from being caught between the door and the door frame are being developed.

The most common is to install an elastic rubber-like material between the door and the door frame to prevent serious injuries due to the elastic material even if hand pinching occurs.

In a more active way, rapid closing of the door is prevented by installing a door hinge or shock absorber that has the function of preventing rapid closing of the door.

Registered Patent No. 10-0813876 “Built-in door hinge with spring restoring force and hydraulic buffering force” was developed. As shown in the representative diagram of Figure 1, this invention

In the door hinge provided at the lower hinge of the door and the door frame, a bracket 120 is inserted into the lower inner side of the door and is formed on one side of the lower outer peripheral surface so that it can be fixed to the door, and a hydraulic regulator 700 is installed at the upper end. ) into which the hollow housing 100 is inserted and at the bottom is rotatably coupled with a hinge holder 250 having a coupling key so as to be coupled to the bottom hinge hole 21 of the door frame 20; It is built into the housing 100, and an expansion member 210 of a predetermined thickness with an O-ring groove 212 formed on the outer peripheral surface is formed on one upper side, and the hinge holder ( a shaft 200 having an extension portion 220 that is slide-coupled to the 250 in a rotation-preventing state, and a protrusion 230 having a predetermined section of the multi-file screw portion 240 formed on the upper side; A first cylinder (600) having a pipe shape, the lower part of which surrounds the expansion member (210) and hermetically coupled inside the housing (100), and the upper part of which is integrally coupled to the hydraulic regulator (700); The first cylinder

A thrust bearing 400 placed on the upper circumferential surface of the expansion member 210 on the inside of (600); It has a pipe shape and is spaced apart from the first cylinder 600 at a predetermined distance inside the first cylinder 600, the lower end of which is placed on the upper surface of the thrust bearing 400, and the upper end of which is the hydraulic regulator 700. ) and a second cylinder (660) that is integrally coupled to the inner peripheral surface and has a spline groove (664) formed in the middle of the inner circumferential surface for one-way guidance up and down in a predetermined section; A spring (300) coupled to surround the extension portion (220) of the shaft (200), the upper end of which is fixed to the expansion member (210), and the lower end of which is fixed to the hinge holder (250); A threaded portion 520 is formed in the inner circumferential hole to be screwed with the multi-lined screw portion 240 provided on the protrusion 230 of the shaft 200, and is coupled to the spline groove 664 of the second cylinder 660 on the outer circumferential surface. A piston 500 on which splines 510 that are guided only up and down are formed, and a check valve 540 is formed at the upper center to allow fluid to move in one direction upward; The fluid in the fluid chamber provided on the upper side of the piston 500 is supplied through the first passage hole 810 formed in the hydraulic regulator 700 and the gap between the first cylinder 600 and the second cylinder 660. A flow path guide means (800) having a second flow path hole (820) for moving to a fluid chamber provided on the lower side of the piston (500); A hydraulic control screw 860 was developed to control the amount of movement of fluid through the first passage hole 810 when the hydraulic regulator 700 is coupled and rotated.

The invention has an automatic closing function using hydraulic force and a spring, but the rapid closing during the closing operation is slowed down by hydraulic power to prevent serious injuries when hands are caught.

While the above invention is a structure built into the inner frame of a door, another registered patent No. 10-0760518, “Close shock absorber for furniture doors,” is representative as shown in Figure 2.

"Relates to a door shock absorber installed in the path where doors such as furniture or sinks open and close; not only has a gap 41 between the rod 23 of the piston 20 and the cylinder 10, but also has a gap 41 on its inner wall. When the valve 40 having the oil path 47 is mounted, a protruding protrusion 50 having a plurality of oil grooves 51 along the longitudinal direction is formed at the distal end of the valve 40. A check valve 60 is mounted on the circumferential surface of the protrusion 50 to reciprocate in a sliding manner along the compression direction of the oil; the oil contained in the oil chamber 11 flows into the oil groove 51 of the protrusion 50. ) and passes through the oil path 47 and the gap 41 of the valve 40 by absorbing the external load generated during the closing process of the furniture door; collision noise generated during the closing process of the furniture door By minimizing this, a quiet indoor atmosphere is created and stability is ensured during the door closing process, leading to the development of a "furniture and door shock absorber."

In the case of the above invention, the interior of the door is installed between the door frame and the door, so that when it is suddenly closed, it collides with the tip of the piston 20, preventing a strong collision with the repulsive force of hydraulic pressure and spring.

The characteristic of the above pre-registered patent is that it uses a hydraulic cylinder and spring to prevent rapid closing during the closing operation.

However, in actual practice, the phenomenon of fingers getting caught occurs not only when the door is closed but also when it is opened. In other words, there is no door that minimizes injuries caused by pinching hands even in all cases of opening and closing the door.

The present invention absorbs and controls the rotational speed energy of the door that occurs at the beginning, middle, and end of opening in the opening and closing operation of a swing door, thereby maximizing the effect of preventing collision with the door frame due to sudden closing and opening of the door, and preventing hand entrapment. We would like to provide a control device.

The present invention specifically seeks to provide a swing door control device that can be adjusted at a desired speed by setting a pattern.

The present invention is an opening and closing energy control unit consisting of a prime controller unit (P) that primarily adjusts the opening and closing energy generated when opening and closing the door and an end controller unit (S) that adjusts the residual energy when the operation of the prime controller unit expires;

A control device for a swing door that includes the opening/closing energy control unit and is installed in conjunction with the door rotation axis to increase or decrease the opening/closing operation speed according to a set pattern was developed.

The present invention absorbs and controls the energy generated when the door is suddenly opened and closed by the prime controller and the end controller, thus preventing rapid closing or opening. In particular, the double pistons linked by two cylinders sequentially absorb and control excessive opening and closing energy at the beginning, middle, and end of opening to prevent shock caused by collision between the door frame and the door, and in particular, maximize the effect of preventing hand entrapment. .

Hereinafter, a detailed description of the present invention will be provided as a representative example with the accompanying drawings. The interlocking door exemplified in the present invention is installed on the inside of a door frame composed of an upper and lower frame and a left and right line frame. In particular, the description will be limited to a structure expressing a door that opens and closes by a hinge-like structure between the door frame and the door. However, this example does not limit the present invention to the detailed description, as the positions or arrangements of individual components may be changed without departing from the spirit and scope of the present invention. In the present invention, terms such as device, unit, and means refer to a unit that processes at least one function or operation, and is implemented through a combination of hardware or software. In the present invention, the door system refers to a collection of independent inventions that operate by assembling a damper door, a general sliding door, and guide rails, dampers, handles, hinges, hinges, sun frames, and upper and lower door frames for operating them, and the operation of the overall system. will be omitted and will be limited to the purpose and components of the invention: two controllers that control the power generated when opening and closing the door, assembly connection devices that connect the two controllers to interlock, and a connection part for installing and operating them on the door frame. Explain. Other than this limited description, descriptions of various parts such as upper, lower, left and right frames, door hinges, etc. required for general door installation are matters that are understood by ordinary experts in the field, and detailed descriptions are omitted.

The present invention includes an opening and closing energy control unit consisting of a prime controller unit (P) and an end controller unit (S) that primarily adjusts the opening and closing motion energy generated when opening and closing the door, and the opening and closing energy control unit is built into the door rotation axis. It relates to a control device for a swing door that controls the opening and closing speed consisting of an interlocking fastener installed to interlock with.

In the present invention, the controller is used to optimally control the speed and strength of the door that occurs during the opening and closing operation of the door. In the present invention, the part that is primarily controlled is called the prime controller, and then in conjunction with the prime control operation, the final control is performed. The two operations of the finishing end controller operate continuously and sequentially in conjunction with each other.

Hereinafter, the prime controller part of the present invention will be described based on Example 1, the end controller part will be explained based on Example 2, and the interlocking part for connecting them will be explained based on Example 3.

Figure 3a of the present invention is a perspective view showing the assembled state of the prime controller part of the present invention, Figure 3b is a perspective view showing the disassembled state of the crime controller part of the present invention, and Figure 3c is a perspective view showing the disassembled state of the prime controller part of the present invention. Another perspective view, Figure 3d is a front view showing the disassembled state of the prime inner cylinder and prime piston of the present invention, Figure 3e is a perspective view showing the disassembled state of the prime inner cylinder and prime piston of the present invention, Figures 3f, 3g, and 3h are The operating states of the prime inner cylinder and prime piston are explained in detail with a front view showing them.

As mentioned above, the prime controller unit (P) receives the energy generated during the opening or closing operation of the door when the door opening or closing operation begins and controls the opening and closing by passing the flow of the built-in hydraulic oil through a fine orifice. It refers to a place where energy of movement is absorbed and controlled.

More specifically,

The connection part (1) is connected to rotate in conjunction with the rotational motion that occurs during the opening and closing operation of the door, and forms a groove 1 (1a) for seating the door connection part (15d) of the linker (15) connected to interlock with the door frame of the door. Formed on the upper side,

A hydraulic oil auxiliary storage tank (3) is installed inside the cylindrical prime cylinder (2) extending long downward from the connection part,

A prime inner cylinder (4), which allows the prime piston (5) to move up and down, was installed on the lower side of the hydraulic oil auxiliary storage tank. The prime inner cylinder is filled with hydraulic oil and is configured to move the hydraulic oil through the upper and side orifices, including the hydraulic oil inlet and outlet (4a), by the up and down movement of the prime piston.

In addition, a seat groove (1d) for a spring that elastically supports the linker is formed on the lower side of the groove 1. Groove 2 (1b) formed on both sides of groove 1 is a place where a pin can be inserted to adjust the raising and lowering of the linker when fastening the door and the door frame.

The connecting portion 1 is inserted into the door frame connecting portion 15b of the linker 15 to interlock with the door frame of the door, and the door connecting portion 15d is inserted into the door side, so that fastening between the door and the door frame is achieved, and the door frame connecting portion 15b is inserted into the door side. The energy generated during the opening and closing operation is transmitted to the prime controller through the linker. Groove 2 (1b) was formed on the side of the connection portion to allow the linker to be arbitrarily attached and detached.

The locking control groove 15e of the linker is exposed to the outside. The user inserts an appropriate pin-like tool from the outside into groove 2 and then adjusts the linker up or down to unlock or unlock the connection between the door and the door frame.

The prime inner cylinder and prime piston will be described in more detail with reference to FIGS. 3D and 3E.

The prime inner cylinder (4) is,

A hydraulic oil inlet and outlet (4a) is formed at the center, downwardly open orifices (4b) are formed at the peripheral portion, and parallel open side orifices (4d) are formed at the lower peripheral portion,

Inside the prime inner cylinder (4), the prime inner piston (5) has a structure that moves up and down as a piston. The prime inner piston has a long, horizontal incision (5c) formed on the upper skirt (5a). The cut part is cut up to the bottom skirt (5a_1) to form a flow path through which hydraulic oil can move. That is, since the lower skirt (5a_1) has been cut, the hydraulic oil flowing in from the hydraulic oil inlet and outlet (4a) can move downward past the lower skirt (5a_1).

A piston shaft 5f is installed below the lower skirt 5a_1 arranged in pairs with the upper skirt 5a of the prime inner cylinder. The prime inner valve ring (5e) surrounding the outer peripheral surface of the piston shaft seals the prime inner cylinder (4) from the lower side and blocks leakage of the built-in hydraulic oil.

The prime inner piston is assembled to enable piston operation on the inner surface of the prime inner cylinder, and the flow of the hydraulic oil storage tank (3) is controlled by the lifting and lowering movements that occur during the opening and closing operation of the door, allowing rapid opening and closing. It functions as a damper to absorb energy generated when the door opens and closes during operation.

Another feature of the prime inner piston (5) of the present invention is that the skirt is installed in an upper and lower double structure.

More specifically, an upper ring (5d) was installed between the upper skirt (5a) and the lower skirt (5a_1) to enable sliding between the upper and lower skirts. Therefore, when the prime inner piston (5) moves up and down, the upper ring (5d) moves up and down, blocking the upper side of the cut-out part (5c_1) of the cut-out part (5c) when it goes down and opening it when it goes up. This is to control the flow of hydraulic oil through the cut-out opening (5c_1).

The hydraulic oil inlet and outlet (4a) is formed as an upper and lower opening with a structure that widens from the upper side to the lower side, so that the resistance is different when it flows out of the storage tank to the outside or vice versa. The operating inlet and outlet are upper and lower, but it can also be formed in the opposite way, or a structure in which a check ball supported by a spring is installed on the upper side. The selection of this configuration can be increased or decreased depending on the size and speed of the operating energy of the door to be installed.

As another feature of the present invention, rod-shaped guide protrusions (2a) are formed on both sides of the prime cylinder (2). The lower door connection part 15d of the linker 15 is assembled and fixed to the connection part 1 forming the groove 1 (1a). With this assembly structure, the connection part is fixed together with the linker fixed to the door frame, and the guide protrusion is also fixed. Therefore, when it receives the force generated by the rotation of the door, it moves horizontally along the guide slot by the fixed guide protrusion. This horizontal movement provides the function of switching the outer housing (7) to a rising, horizontal, and falling motion when the prime inner piston (5) rises and falls, that is, it provides an operation pattern when opening and closing the door. Specific explanations are provided again below.

The flow operation of the internal hydraulic oil due to the operation of the prime inner cylinder and the prime inner piston is explained by the operation examples of FIGS. 3F, 3G, and 3H.

The explanation will be made on the premise that the door is arranged as shown in Figure 3f before the opening or closing operation occurs. When the door opens (or closes), the door rotates. The prime cylinder containing the prime inner piston (5) moves up or down. Accordingly, the external housing 7 achieves a defined operation pattern such as rising, horizontal, and descending movements along the guide slot 7a. The specific situation according to this operation pattern is that as the prime inner piston moves forward in the state of FIG. 3g, hydraulic oil moves through orifices formed at the center and both ends of the prime inner cylinder as indicated by arrows A and A'. This movement is selected to be most optimal for the door to be applied by adjusting the diameter of the orifice and the viscosity of the operating oil to be used. Then, when the lowering motion occurs again, the hydraulic oil moves as shown by arrows B and B' in Figure 3h, absorbing and buffering the energy generated by the rotating motion of the door again. This action prevents sudden closing or opening when the door is opened and closed, minimizing problems such as impact on the door frame or fingers getting caught between the door frame and the door.

A specific example of a prime controller that induces the operation of the prime inner cylinder and prime inner piston of the present invention will be described with reference to the attached drawings,

"로 구성하였다. Guide protrusions (2a) on both sides of the outer peripheral surface of the prime cylinder (2) are installed to be slidable in the guiding slots (7a) of the outer housing (7). The guide slot (7a) of the outer housing (7) is structured to surround the entire outer circumference of the prime controller, and as shown, slopes downward toward both sides, but is in a balanced state near the center.

"It was composed of.

Since the inserted guide protrusion (2a) is fixed to the door frame by a linker so that it cannot be raised or lowered, the guide slot formed in the above-mentioned external housing In the form of , it induces rising, horizontal, and descending movements such as the initial rising movement of the external housing, the horizontal movement of the central part, and the final falling movement. In this operation, the prime piston (4), which is interlocked with the opening or closing operation of the door, moves upward, horizontally, and downward, so when it rises, the hydraulic oil flows through the narrow passage of the hydraulic oil inlet and outlet (4a), and the prime piston is moved by the resistance of the hydraulic oil. It prevents the rapid movement of the door, and as a result, prevents rapid opening or closing when the door is opened (or vice versa). When the horizontal motion is continued, there is no movement of the prime piston, so there is no resistance, and the door moves to its original operating state. If the lowering motion is then entered again, the flow of hydraulic oil is interrupted, preventing sudden closing (or opening). This action prevents rapid movement of the door that occurs when the door is opened (or closed).

As described above, the prime controller of the present invention absorbs the initial rapid energy in the entire process from the start of the door opening operation to the final operation, and in the middle, the door opening and closing operation is performed with the remaining absorbed energy, and then absorbs and removes the energy again. It is made up of actions. Therefore, a dual damper function is provided to block sudden opening or closing of the door not only when it is opened but also when it is closed.

As mentioned above, the present invention provides a sufficient damper function by installing the prime controller alone on various doors such as general homes and offices. However, if the opening and closing energy applied to the door is strong and adjustment is difficult, the end controller unit described below is installed to provide a sufficient damper function. A safe damper function was provided.

The unexplained symbol 5g of the prime controller has the function of blocking the lower side of the prime inner cylinder.

The end controller unit (S) of the present invention will be described based on drawings showing representative embodiments of FIGS. 4A, 4B, and 4C.

The end controller part of the present invention,

The piston shaft 5f of the prime controller part P penetrates the bottom of the external housing 7 and is assembled integrally with the upper part of the secondary cylinder 8. Since the secondary piston (8a) is built into the secondary cylinder (8), when the prime inner piston (5) moves up and down, the secondary cylinder (8) also moves up and down in conjunction with it, so the secondary piston (8a) also moves up and down. It comes true. On the upper side of the secondary cylinder, an upper fastening protrusion (8e) is installed to interlock with the prime control unit and is integrally fastened. An O-ring (8b) was placed between the secondary piston (8a) and the secondary cylinder (8) to provide appropriate resistance when the piston moves up and down. Therefore, the primary control unit operates in conjunction with the primary control unit to provide a secondary damper function by absorbing energy during the door opening and closing operation. As a result, even if there is a strong impact due to strong wind or sudden force when opening or closing the door, the impact energy can be minimized, showing a dramatic effect in preventing strong collisions between the door and the door frame and preventing hand pinching. do.

The specific operation of the end controller unit is as shown by the arrow in FIG. 4C,

With the opening and closing operation of the door, the prime inner piston (5) of the prime controller unit assembled integrally with the connection part (1) rotates as shown by arrow A. By this movement, the guide slot (7a) of the external housing is opened. " moves as shown by arrow B. This movement movement is performed forward and backward as shown by arrow C, and the prime inner piston (5) and secondary piston (8a) of the above-described prime controller part (P) move within the cylinder. When the secondary piston (8a) moves, the secondary O-ring (8b), which is in contact with the inner wall of the secondary cylinder, is in frictional contact with the inner side of the cylinder, thereby providing friction during the lifting and lowering operation by the secondary piston (8a). It absorbs the sudden rotational energy of the door again and blocks rapid closing or opening.The friction reducing material to be installed between the secondary piston (8a) and the secondary cylinder provides friction force that is appropriately selected according to the speed and size of the door when opening and closing. You can choose the optimal material to give.

Another feature of the end controller part is that a screw fastening part (8d) is installed on the lower side of the secondary cylinder (8). The screw fastening part is fastened from the outside with a conventional nut. The present invention makes it possible to arbitrarily adjust the damping function that the end controller can accept by adjusting the assembly depth when tightening the difference in various operating energies, such as the size and operating range of the door to be installed, during fastening assembly. For example, the operating range. If it is wide or the force to be received is large, increase the screw fastening height so that it can receive a strong range of interlocking motion with the prime controller part. In the opposite case, assemble it low.

The above-described primary control unit and end control unit are installed on the door frame and built into an external housing for operation, and are finally installed between the door and the door frame using caps and fixtures at the top and bottom.

Specifically, Figures 5a, 5b, and 5c illustrate the interlocking fasteners for the configuration and installation state for installing the prime controller portion and the end controller portion according to the above-described first and second embodiments on the door and door frame. Explain. The state of assembling the prime controller unit and the end controller unit, then assembling the upper cap and then assembling it into the out housing is explained with reference to FIGS. 6A, 6B, 6C and 6D.

The prime control part built in the above-mentioned external housing (7) and the end control part built in the secondary cylinder (8) are built in the controller housing (9),

The upper end of the controller housing is fastened with the upper cap (10), and the lower end is fastened to the screw fastening portion (8d) on the lower side of the secondary cylinder (8). The prime controller portion and the end controller portion are fixed to the inside of the controller housing by screwing from the outside.

The lower part of the controller housing is formed to penetrate the screw fastening portion 8d on the lower side of the secondary cylinder 8 and is fixed from the outside with a normal nut fastening.

The controller housing is installed at a part connected to the door frame, such as a door hinge or hinge, and can be configured in various ways depending on the shape and type of the door. In the present invention, the most common form, a circular shape, is exemplified.

The controller housing described above is provided with a detachment control groove (9a) on the side, and is exposed to the outside of the controller housing by this detachment control groove. The linker 15 is elastically supported in an upward direction by a spring at the bottom. Therefore, when the user performs a downward operation using a pin insertable in the locking adjustment groove 15e, the entire linker descends, and the upper part of the linker separates from the installation groove provided in the door frame, so that it can be separated from the device of the present invention. This installation performs the same function even if it is installed at the bottom rather than the top.

The linker 15 of the present invention will be described.

The linker is a door frame connecting portion (15b) penetrating the central hole of the upper cap (10),

A body (15c) extending long below the upper protrusion,

A door connection part (15d) extending long to the lower side of the body,

And it consists of rod-shaped locking adjustment grooves 15e extending and protruding from both sides of the central body.

A spring insertion hole capable of fixing a spring for elastic support is installed in the door connection part (15d), and a part of the door frame connection part is inserted into groove 1 (1a) formed in the connection part (1) of the prime controller. , the spring is inserted into the seat groove (1d) and is elastically supported. Due to the repulsive force of the spring, the linker is constantly inserted into the door frame connecting portion (15b) into the linker fastening groove (20) of the door frame, thereby establishing a connection between the door frame and the door.

As described above, once the prime controller and end controller are built-in and assembled in the controller housing (9), they are re-embedded in the out-housing (14) for final assembly to the door frame and door, and then the upper and lower parts are connected to the upper fixing member (16). Fasten with fixing member (17).

In the outer housing, a locking adjustment hole (14a) was formed so that the locking adjustment groove (15a) was exposed to the outside in order to disassemble the door by the linker described above. The locking adjustment groove 15e described above in this locking adjustment hole is always kept partially exposed to the outside, and is used when assembling or dismantling the door and door frame.

A locking protrusion is formed on one side of the controller housing 9 of the present invention, and the locking protrusion is fitted inside the out housing 14. Therefore, the controller housing and out housing are configured to operate together.

Another feature of the connection part 1 of the present invention is as shown in the partially enlarged view showing the disassembled state of FIG. 6D,

A locking protrusion (2f) is formed on the upper inner surface so that the lower end of the body (15c) of the linker is caught here. The connection and separation between the door and the door frame are accomplished by the linker. After the door and the door frame are fastened through a linker, the elasticity of the spring decreases and the linker cannot be supported upward, or when deformation occurs in the door frame or door, the linker cannot elastically support the door frame. . In this case, even if the door opens and closes, the operating energy from this rotation is not transmitted to the above-mentioned prime controllers and slips, failing to achieve the intended effect. However, the width of the lower side of the body 15c of the linker in the above-mentioned locking protrusion is configured to be larger than the locking protrusion to prevent further lowering. Therefore, further linker descent was prevented to eliminate the problem of malfunction that could occur when used for a long period of time.

Furthermore, in order to fix the linker in the correct position, a cap locking protrusion is installed on the inside of the upper cap 10. Accordingly, the linker is seated between the above-mentioned locking step (2f) and the cap locking step to prevent further upward and downward movement.

The door control device of the present invention according to the above-described configuration shows a state in which the linker 8 is assembled to the prime controller and end controller portion consisting of a prime cylinder, a prime inner cylinder, and a linker, etc., in Figure 6a, and Figure 6b shows the present invention. This is a perspective view of the linker in the assembled state. Figure 6c shows an out housing containing a prime controller unit and an end controller unit consisting of a prime cylinder, a prime inner cylinder, a secondary cylinder, and a linker, and a linker (15) in the controller housing, followed by a fixing member (11) for fixing to the door frame and door. This is a perspective view of the installed state.

In the present invention, an appropriate thrust bearing can be installed on the inside of the upper cap according to the installation situation to reduce severe resistance caused by a heavy door, and anyone skilled in the art can install these thrust bearings.

With the structure described above, even when the prime controller unit and the conventional end controller unit receive an unexpectedly strong impact during the opening or closing operation of the door, they are cushioned by the above-mentioned damper gas and the cooperative action of the hydraulic fluid by the lifting piston. It made it possible to cushion the impact more reliably. Due to this configuration, shock can be cushioned even when applied to industrial doors rather than general households, greatly expanding its use, and making it possible to provide a variety of buffer doors tailored to consumer needs.

The present invention is an opening and closing energy control unit consisting of a prime controller unit (P) that primarily adjusts the opening and closing energy generated when opening and closing the door and an end controller unit (S) that adjusts the residual energy when the operation of the prime controller unit expires. It absorbs and removes the shock between the door frame and the door that occurs when the door is suddenly closed or opened during the opening or closing operation of the door. Furthermore, it buffers the sudden closing and opening by sequentially absorbing and removing the energy of the door opening and closing operation, thereby cushioning the door frame and the door. Minimized safety accidents involving hands being caught.
