The door 20a, The upper side of each of the opening and closing ports 20 made up of the movable door 20b and the movable door 20c is engaged in each of the passages 11 and smoothly reciprocatingly sliding.

That is, the fixed door 30a located inside the plurality of doors 30a, 30b, and 30c is fixed to the upper chassis 10, and when the handle door 30c is opened and closed, And the middle door 30b is also opened and closed together.

20b and 20c which are attached to the upper surfaces of the slide doors 30a, 30b and 30c of the present invention and are reciprocally moved within the passageway 11 of the upper chassis 10 as shown in Fig. 10, The movable door 20c attached to the upper surface of the fixed door 30a fixed from the inside is fixed in position and the movable door 20c attached to the door 30c opened and closed at the door is opened When they are moved, the openings 20a, 20b and 20c are formed on the same horizontal plane so that the openings 20a, 20b and 20c are narrowed by the fixing table 21.

To be more specific, a rotary roller is attached to both ends of the intermediate movable opening / closing port 20b located at the intermediate portion, which is rotated by one closed-loop belt.

The belt fixed to the fixing table 21 is moved so that the rotating roller is rotated and thereby the intermediate position between the moving opening 20c and the intermediate portion connected thereto is moved The opening / closing ports 20b are connected to each other to move horizontally, and the distance between them changes.

Since the opening and closing ports 20a, 20b and 20c are fixed to the upper surfaces of the corresponding doors 30a, 30b and 30c respectively, when the handle doors 30c are opened and closed, The door 30b is also opened and closed together.

Fig. 11 shows slide openings 20a, 20b and 20c, respectively, which are smoothly reciprocated horizontally in the passage 11 of the upper chassis 10. The openings 20a, 20b, And are fixedly attached to the upper surfaces of the corresponding slide doors 30a, 30b, and 30c.

A locking protrusion 12 is protrudingly formed on one plane of a passage located at an intermediate position in the passage 11 and a locking portion 52 of a speed adjusting damper 50 is engaged with the locking protrusion 12, So that the engaging part 52 is horizontally moved when the cover 30 is opened or closed.

As shown in FIG. 12, the slide door 20, which is smoothly reciprocatingly engaged with each passage 11 of the upper chassis 10, is fully opened. A speed adjusting damper 50 is fixedly attached to a plane of the intermediate moving opening and closing port 20b positioned in the middle of the opening and closing port 20 to move together with the sliding movement of the opening and closing port 20 in the horizontal direction, The function of buffering the speed control damper 50 is added to buffer the opening speed at the starting point of opening of the closed door and to control the closing speed at the time of fully closing to buffer.

In addition, since the two fixing tables 21 are fixed to the respective rotating belts, when the movable door 20c moves horizontally, the intermediate movable door 20b of the middle portion is also moved together, and the intermediate movable door 20b The speed-adjusting damper 50 fixedly attached thereto is also moved together with the latching jaw 12 so as to be engaged or disengaged, thereby giving the door 30 a buffering function.

As shown in FIG. 13, this shows the engagement protrusion 12 attached to the plane of the intermediate passage of the passage 11 of the upper chassis 10, and the speed adjustment, which is fixedly attached to the intermediate movement opening / The damper 50 and the opening and closing port 20b are fixed to the upper surface of the slide middle door 30b so that the opening and closing port 20b is horizontally reciprocated integrally with the door when the door 30 is opened and closed .

Fig. 14A shows a state in which the door 30 is opened, and Fig. 8B shows a state in which the door 30 is being opened and a state in which the door 30 is closed.

 This is because when the door 30 is completely closed, the engaging portion 52 of the speed adjusting damper 50 fixed to the middle door 30b is caught by the engaging jaw 12, and the handle door 30c starts to be opened The spring 55 is extended and the elastic force is increased so that even if the handle 30C is strongly opened, the spring 55 of the middle door 30b It will be pulled and slowly opened.

 As a result, even if the door is strongly opened, a slow opening effect is generated, so that a buffering function is imparted and the door is stable.

When the handle door 30c and the middle door 30b are continuously opened, the speed adjusting damper 50 (see FIG. 5) fixed to the middle door 30b is detached from the engaging jaw 12, And the spring 55 is maximally extended. The damper 52 is connected to the damper 52 at the same horizontal position as the damper 52, The rod 54 will be in its maximum extended state.

The speed adjusting damper 50 is displaced from the position of the engaging jaw 12 and the speed adjusting damper 50 is moved out of the position of the engaging jaw 12 when the door 30 is continuously opened in the above state as shown in the first diagram (c) The spring 55 and the damper rod 54 are kept at the maximum stretched state and fixed to the upper portion of the door 30b and horizontally moved together.

As shown in the second diagram (d) of FIG. 14 (b), when the door is closed again in the open state of FIG. 14 (c) and the door is kept closed, the engagement portion 52 of the speed- 12, and the engaging portion 58, which is inserted into the engaging groove 53, is released from the groove 53.

 When the handle door 30c and the intermediate door 30b are closed together at a certain point in the traveling state, the engaging jaw 12 is provided with the engaging touch portion of the speed adjusting damper 50 of the intermediate door 30b, The engaging jaw 12 is completely engaged with the engaging part 52 while the engaging protrusion 57 touches the engaging groove 53. At the same time, the engaging insertion part 58 inserted and received in the engaging groove 53 is withdrawn, As the spring 55 is loosened, the damper rod 54 gradually falls into the cylinder due to the elastic restoring force.

The middle door 30b is closed even if there is no external force due to the spring force of the spring 55. The handle door 30c connected to the intermediate door 30b is naturally forced The effect that the maximum spring 55 is gradually reduced due to the damping action of the damper rod 54 is generated even if there is no force.

As a result, the middle door 30b and the handle door 30c are gradually closed like an automatic door without an external force or a power unit.

As shown in FIG. 8C, when the damper rod 54 enters the cylinder, it functions as a buffer for reducing the closing speed of the door 30 by the damping liquid pressure filled in the cylinder. Therefore, even if the handle door 30c is strongly closed, the door 55 is gradually closed by the spring 55 and the damper rod 54 from a certain point before the door frame is completely closed, so that an unpleasant feeling such as shock or noise is not generated I will not.

The speed adjusting damper of the present invention is attached to the upper surface of a door positioned at an intermediate position among a plurality of slide doors. Therefore, the conventional speed adjusting damper is less in slide pressing force than a door system attached to a handle door It is necessary.

When the door is opened by attaching a speed-adjusting damper to the door of the bar-like handle, a resistance is generated from the damper from the start of pushing the door, and a force for opening the door is further needed. The door suddenly opens, and the speed at which the door is opened unintentionally increases, thereby giving a buffering function that eliminates the phenomenon in which the door is opened and closed. However, the user is given more power than necessary, .

10 to 15, which are another embodiment of the present invention,

3 to 9, the present invention relates to a door system that provides a buffering function with less force than the conventional door system.

The damper 50 attached to the middle door 30b moves without any movement and the handle 30c is continuously opened by the handle 30c. The interconnecting intermediate door 30b is opened next and the speed adjusting damper 50 attached to the intermediate door 30b starts to operate.

Since the middle door 30b starts to move due to the acceleration generated when the handle door 30c is opened and closed, the force required for the user to open and close is added to the force of the acceleration, It will be done.

8A to 8C, when the speed regulating damper 50 is fixedly attached to the handle door 30c, the engaging jaw 12 is provided at a position where the handle door 30c is closed The handle 55 is released and the handle door 30c caught by the stopping jaw 12 is automatically rotated by the force of the spring 55 which is released on the basis of the stopping jaw 12, An automatic movement distance is generated in which the door is gradually closed.

14A to 14C illustrate another embodiment of the present invention in which a speed adjusting damper 50 is attached to the middle door 30b and the spring 55 of the speed adjusting damper 50 fixed to the middle door 30b The middle door 30b and the handle door 30c are gradually closed together at the same time and the moving distance of the handle door 30c which is automatically closed gradually by the force of the spring is twice as large as before, You will need less.

This will be described in detail as follows.

10, the moving distance of the moving door 20c attached to the handle door 30c is twice as long as the moving distance of the intermediate moving door 20b fixed to the middle door 30b. To explain this, the middle door 30b and the handle door 30c are mutually connected and moved at the same time.

This is not related to the configuration of the opening and closing port 20 made of the rotating belt shown in Fig. 10 and is a feature of the multi-slide door system in which the fixed door 30a, the middle door 30b and the pull door 30c are mutually connected It is a clear feature that the distance between the middle door 30b and the handle door 30c is twice as large even if other types of doors are used.

For example, when the middle door 30b is moved by 10 mm, the handle door 30c is moved by 20 mm.

Therefore, when the spring 55 of the speed adjusting damper 50 fixed to the intermediate door 30b is caught by the latching jaw 12, the middle door 30b and the handle door 30c The distance that the handle door 30c moves is twice as much as the distance that the middle door 30b moves when the middle door 30b is closed. Therefore, when pushing with the same force as that of the conventional door system of FIG. 10, Since the moving distance of the door 30c to be closed is doubled, the feature of the present invention is that it is characterized by a plurality of sliding doors with less pressing force.

The present invention is characterized in that the automatic moving distance at which the door is automatically closed by the elastic spring is increased to twice or more than the restoring length of the elastic spring to increase the automatic moving distance at which the door is completely closed And three doors. However, the technical scope of the present invention is also applicable to a case where there are three or more doors.

Therefore, another embodiment of the present invention is to provide a method of manufacturing a door system that requires less pushing force since a user can open and close the door with less force.

The present invention relates to a method for operating a speed adjusting damper and a latching jaw in such a manner that a speed adjusting damper is mounted on an upper end of a door to be opened and closed and a latching jaw is formed on a fixed door frame,

A further embodiment of the present invention relates to a method for operating a speed adjusting damper and a latching jaw in such a manner that a speed adjusting damper is fixedly mounted on a fixed door frame with a latching jaw mounted on the top of an open and closed door .

Therefore, FIG. 16 is a schematic view showing a state in which the mounting positions of the speed adjusting damper and the stopping jaw are changed and engaged with each other as a further embodiment of the present invention. FIG. 17 Fig. 17B is a schematic view showing a slide door which is opened and closed by a speed adjusting damper as an embodiment of Fig. 16 of the present invention. Fig. 17B is a schematic view showing a slide door opened by a speed adjusting damper.

Fig. 16 is a view showing a modification of the vertical installation position of the engagement jaw and the speed-adjusting damper in Fig. 11, and the operating principle and method are the same.

Figure 16 shows slide openings 20a, 20b and 20c which are respectively coupled in the passageway 11 of the upper chassis 10 and smoothly reciprocating horizontally. The openings 20a, 20b and 20c And are fixedly attached to the upper surfaces of the corresponding slide doors 30a, 30b, and 30c.

A speed adjusting damper 50 is protrudingly formed on one plane of a passage located at an intermediate position in the passage 11 and a locking protrusion 12 is formed on the slide opening and closing port 20b, The latching portion 52 of the speed adjusting damper 50 is hooked and the latching portion 52 is moved horizontally when the door 30 is opened or closed.

Fig. 17A shows a state in which the door 30 is opened. Fig. 17B shows a state in which the door 30 is being opened and a state in which the door 30 is closed.

 This is because when the door 30 is completely closed, the engaging protrusion 12 formed on the intermediate door 30b is engaged with the engaging portion of the speed regulating damper 50, 52 and the handle door 30c starts to be opened and the intermediate door 30b is opened at any point so that the spring 55 is stretched to increase the elastic force so that the handle door 30C Even if it is strongly opened, it is pulled by the spring 55 of the middle door 30b and is opened slowly.

 As a result, even if the door is strongly opened, a slow opening effect is generated, so that a buffering function is imparted and the door is stable.

The position of the speed adjusting damper 50 is fixed so that when the pull door 30c and the middle door 30b are continuously opened, the speed adjusting damper 50 is released from the speed adjusting damper 50, And the spring 55 is maximally extended and is connected to the same horizontal portion as the engaging portion 52. The engaging portion 58 is inserted into the engaging groove 53 formed in the downward direction, The damper rod 54 is placed in a state of being extended to the maximum length.

As shown in the first drawing (c) of FIG. 17B, when the door 30 is continuously opened in the above state, the latching jaw 12 passes through the speed adjusting damper 50 without being caught by the speed adjusting damper 50, The spring 55 of the speed adjusting damper 50 and the damper rod 54 are kept at the maximum stretched state and fixed to the upper portion of the door 30b It is being moved horizontally together.

As shown in the second diagram (d) of FIG. 17 (b), when the door is closed again in the opened state of FIG. 17 (c) and the door is kept closed, the engagement portion 52 of the speed- 12, and the engaging portion 58, which is inserted into the engaging groove 53, is released from the groove 53.

 When the handle door 30c and the intermediate door 30b are closed together at a certain point in the traveling state, the engaging jaw 12 is provided with the engaging touch portion of the speed adjusting damper 50 of the intermediate door 30b, The engaging jaw 12 is completely engaged with the engaging part 52 while the engaging protrusion 57 touches the engaging groove 53. At the same time, the engaging insertion part 58 inserted and received in the engaging groove 53 is withdrawn, As the spring 55 is loosened, the damper rod 54 gradually falls into the cylinder due to the elastic restoring force.

The middle door 30b is closed even if there is no external force due to the spring force of the spring 55. The handle door 30c connected to the intermediate door 30b is naturally forced The effect that the maximum spring 55 is gradually reduced due to the damping action of the damper rod 54 is generated even if there is no force.

As a result, the middle door 30b and the handle door 30c are gradually closed like an automatic door without an external force or a power unit.
