Hereinafter, a sliding door buffer structure having a common stopper according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The sliding door buffer structure of the present invention comprises a door leaf support frame (3), a stop damper (5), and a stop damper (7) as shown by reference numeral 1 in FIG.

Here, the door leaf support frame 3 is a part for movably supporting the inner and outer doors Di, Do that are opened and closed along the door frame F, as shown in FIGS. 3 to 6, the door frame F ) In the transverse direction, that is, in the direction of movement of the inner and outer doors (Di, Do), the bar is installed, as enlarged in Fig. 6, to the fixed frame body 11 and the moving frame body 13 again. Is composed.

Here, as shown in Figs. 3 to 6, the fixed frame body 11 is mounted and fixed along the upper edge of the door frame F to support the inner and outer doors (Di, Do) to be movable. , As shown in FIG. 6, the inner and outer door rails (15, 17) are formed to support the inner and outer door rollers (21, 23) to be rollable below the upper edge of the door frame (F), and in particular, the inner door leaf By supporting the inner door leaf roller 21 by the rail 15, the inner door leaf Di is directly supported to be movable.

In addition, the movable frame body 13 is mounted to be movable in the transverse direction along the fixed frame body 11 as shown in FIGS. 3 to 6 to support the outer door (Do) to be movable, As shown in Figure 6, the inner end adjacent to the door frame (F) is supported to be movable along the outer door leaf rail 17 through the outer door leaf roller 23 is installed on the fixed frame body (11). In addition, the door frame (F) of the moving frame body 13 and the outer end of the far side are coupled to the outer door leaf (Do), and the moving frame body 13 attaches the outer door leaf (Do) to the fixed frame body (11). Support to be movable.

The stopping damper 5 is a means for preventing the vertical frame V of the door frame F from colliding with the inner and outer doors Di, Do, as shown in FIGS. 3, 4, and 6, It is mounted on the door leaf support frame 3 so as to be disposed at both corners of the upper end of the door frame F adjacent to the vertical frame V, that is, at the first correct position. At this time, the stopping damper 5 is, as shown in Figs. 4 and 6, so that the collision site with the vertical frame V is different from each other when the door is closed, as shown in Figs. It consists of a door leaf stopping damper (5-1) and an outer door leaf stopping damper (5-2). Therefore, the inner door leaf stopping damper 5-1 prevents the inner door leaf Di from colliding with the vertical frame body V, and the outer door leaf stopping damper 5-2 is the outer door leaf Do being the vertical frame body V ) To prevent collision.

To this end, as shown in Figure 6, the inner door stop damper (5-1) is mounted on the bottom of the inner and outer door rail (15, 17), the outer door stop damper (5-2) is the inner and outer door rail It is mounted on the top of (15,17). However, the outer door stop damper 5-2 is disposed adjacent to the inner surface of the fixed frame 11 at the side of the inner and outer door rails 15 and 17 so as not to cause interference with the inner door roller 21. In addition, as shown in Figs. 4 and 6, the inner door stop damper 5-1 is arranged upside down so that the stopping protrusion 24 comes toward the inner door stopper 41 to be described later, so that the inner door stopper 41 Operation is possible. In addition, the outer door stop damper (5-2) is disposed immediately so that the stopping protrusion 24 comes toward the common stopper 45, which will be described later, so that the operation by the common stopper 45 is possible. In addition, the inner and outer door stop dampers (5-1, 5-2), as shown in Figure 6, the insertion protrusions (25) protruding from both corners of the lower end protrudes to the upper and lower surfaces of the fixed frame (11), respectively. It is fitted to the guide groove 27 and coupled to the fixing frame body 11 in a dovetail shape, and is fixed to the fixing frame body 11 by bolts 29 fastened to the ends, as shown in FIG. 3.

The stop damper (7) stops the movement of the outer door (Do) so that it can be stopped at a position spaced apart from the vertical frame (V) of the door frame (F), for example, at the center position of the door frame (F). , As a means of minimizing the impact that occurs when stopping, as shown in FIGS. 3, 5, and 6, the outer door (Do) is arranged in a position to stop midway, that is, the second fixed frame It is fixed to the sieve (11). In particular, as will be described later, the stop damper 7 prevents the movement of the common stopper 45 so that the outer door Do can stop moving at the second correct position, as shown in FIG. 6, the outer door stop damper ( 5-2) Bar mounted on the inner surface of the fixed frame 11 from above, at this time, when the common stopper 45 is closed, the movement is blocked by the outer door stop damper 5-2 and is closed. ) Also relieves the impact. To this end, the stop damper 7 is disposed upside down so that the stop protrusion 31 comes toward the common stopper 45 to be described later, so that the operation is possible by the common stopper 45.

On the other hand, the inner and outer doors (Di, Do) operate the stop damper (5) or the stop damper (7) as described above so that it is buffered and stopped by the reaction force, the stopping protrusion (24) or the stopping damper (7) of the stopping damper (5). ) Having an operating means for actuating the stop protrusion 31 of the bar, as shown in Figs. 4, 6 and 7 to operate the inner door stop damper 5-1, The inner door stopper 41 is mounted at the bottom of the roller bracket 33. At this time, the roller bracket 33 of the inner door leaf (Di) is installed in the upper corner portion toward the vertical frame body (V) of the inner door leaf (Di), as shown in FIG. 7, and the inner door leaf roller 21 is mounted. It is supposed to be. In addition, as shown in Figs. 5, 6, and 8 to operate the outer door stop damper (5-2) and the stop damper (7), the inner door roller 21 at the inner end of the moving frame body 13 ) A common stopper 45 is mounted in the adjacent area. Therefore, the common stopper 45 is to be stopped by the outer door stop damper (5-2) or the stop damper (7) while moving along the outer door (Do), the inner and outer door rails (15, 17) It is mounted on the outer surface of the moving frame body 13. At this time, the moving frame body 13 is coupled to the roller bracket 35 of the outer door (Do) as shown in Figure 8, the outer end, this roller bracket 35, like the roller bracket 33, the outer door It is installed in the upper corner toward the vertical frame (V) of (Do).

Here, the upper inner door stopper 41 is a bar that protrudes from the upper end of the inner surface of the body 42 in the form of a block shape of a rectangular parallelepiped, as shown in FIGS. 43) pressurizes the stopping protrusion 24 of the inner door stop damper 5-1 so that the inner door stopper 41 is engaged with or released from the stopping protrusion 24 by elastically lifting and lowering.

In addition, the above common stopper 45, as shown in Figs. 6 and 8, the body 46 in the form of a rectangular parallelepiped block is arranged side by side on the moving frame body 13 and attached, to the stopping protrusion 24 The wing-shaped transverse protrusion 47 protrudes horizontally toward the stopping protrusion 24 at the middle of the inner surface of the body 46 so that it can be caught. In addition, the partition-type vertical protrusion 49 in the form of a blunt dovetail protrudes upward toward the middle protrusion 31 so that the wing-shaped transverse protrusion 47 can be caught in the middle protrusion 31 in the middle of the upper surface transverse direction. Thus, the common stopper 45 is when the outer door (Do) is closed, that is, when approaching the vertical frame (V), the horizontal protrusion 47 is the stopping protrusion 24 of the outer door stop damper (5-2) As the movement speed is attenuated by being caught, collision with the vertical frame V is prevented, and finally the outer door Do is stopped at the first normal position, that is, the closed position. On the other hand, when the outer door (Do) is spaced apart from the vertical frame (V) and reaches the second correct position, the vertical protrusion 49 is caught by the middle protrusion 31 of the stop damper 7 and stops from the vertical protrusion 49 When the force applied to the protrusion 31 is less than the elastic resistance of the middle protrusion 31, the outer door leaf Do is gradually reduced in speed by the middle protrusion 31, gradually reducing its movement and stopping at the second position. do. However, after stopping, the user applies a force greater than the elastic resistance force of the middle protrusion 31, or the force applied from the vertical protrusion 49 to the middle protrusion 31 when the second normal position is reached is the middle protrusion 31 When greater than the elastic resistance of the vertical protrusion 49 is released from the middle protrusion 31, it may be further moved in the direction of travel together with the outer door (Do).

Now, when explaining the operation of the sliding door buffer structure (1) having a common stopper according to a preferred embodiment of the present invention as follows.

According to the buffer structure (1) of the present invention, when first closing the inner door (Di), the inner door stopper 41, as shown in Figs. 4 and 6, the inner door stop of the damper (5-1) It is caught on the protrusion 24, but initially combined with the stopping protrusion 24 as shown by a hidden line in FIG. 4 and moving toward the vertical frame (V), but the spring inside the inner door stop damper 5-1 and/ Alternatively, the moving speed is gradually decreased by the damping cylinder or the like, and eventually stops at the first fixed position shown by the solid line. On the contrary, when the inner door stopper 41 is opened in a closed state, it moves in a direction away from the vertical frame body V together with the stopping protrusion 24 in the solid line position of FIG. 4, but the stopping protrusion 24 at the position shown by the hidden line. ) And continues to open to the right on the drawing. At this time, the stopping protrusion 24 has elasticity and descends downward, allowing separation of the inner door stopper 41 and then returns to its original position.

On the other hand, when closing the outer door (Do), although not shown separately, as in the case of closing the inner door (Di) of Figure 4, the common stopper 45 as shown in Figure 6, the horizontal projection 47 is outside It is caught by the stopper (24) of the door stop damper (5-2) and moves toward the vertical frame (V), but its movement speed is increased by the spring and/or damping cylinder inside the outer door stop damper (5-2). It gradually decreases, and eventually stops at the first correct position. On the contrary, when the common stopper 45 is opened in a closed state, it moves in a direction away from the vertical frame body (V) together with the stopping protrusion 24, like the inner door stopper 41 of FIG. 4, but the horizontal protrusion ( As 47) separates from the stopper 24, it continues to open in the same direction. At this time, the stopping protrusion 24 similarly has elasticity and is pushed down to allow separation of the common stopper 45 and then returns to its original position.

In particular, the common stopper 45 is used not only to operate the outer door stop damper (5-2) as above, but also to operate the stop damper (7), as shown in Figure 8, at the left end of the drawing When moving to the right and catching the stopping protrusion 31 of the stopping damper 7 at the second correct position, it continues to move in the same direction with the stopping protrusion 31, but the spring and/or damping inside the stopping damper 7 Its moving speed is gradually reduced by a cylinder or the like, and it stops at a critical position shown by a hidden line. Soon after, the common stopper 45 and the middle protrusion 31 move in the opposite direction due to the reaction force of the middle protrusion 31 and pass through the second correct position, but change the direction to the opposite direction, that is, to the right. By the reaction force of (31), it converges to the second correct position and stops.

However, the common stopper 45 is in the stopped state, the user moves the outer door (Do) to apply a force greater than the elastic resistance of the stop protrusion 31 to the middle protrusion 31, or reach the second original position When the force applied to the middle protrusion 31 from the vertical protrusion 49 is greater than the elastic resistance of the middle protrusion 31, the middle protrusion 31 has elasticity and is pushed upward to prevent the separation of the common stopper 45. Allow it and return to the original position. Accordingly, the vertical protrusion 49 is released from the middle protrusion 31 at the critical position shown by the hidden line in FIG. 8, and further moves in the traveling direction together with the outer door member Do.

In this way, when the inner door leaf (Di) is closed, the inner door leaf stopper 41 is caught/released with the stopping protrusion 24 of the inner door leaf stopping damper 5-1 by the inner door leaf stopping damper 5-1. It is buffered against the vertical frame body (V), and when the door is closed, the common stopper 45 is caught/released with the stopping protrusion 24 of the outer door stop damper (5-2), and the outer door stop damper ( It is buffered against the vertical frame V by 5-2). In addition, when the outer door (Do) stops while the common stopper 45 is caught/released with the stop protrusion 31 of the stop damper 7 at the second correct position, the stop protrusion 31 by the stop damper 7 ) And the impact is alleviated.
