Shock Absorber for Doors
[15] The present invention relates to a door shock absorber, and more particularly, to a door hinge interposed on one side of various doors to enable smooth angular movement of the door, the door hinge being mounted to the door hinge to prevent sudden closing of the door. The present invention relates to the provision of a shock absorber.
[16] In general, the door hinge is interposed in various doors of the sliding type, the door through the door hinge is to enable the opening and closing action by repeating a constant angular movement from this.
[17] The door hinge has various shapes and structures according to the type and application of the door. Among them, the door hinge 1 shown in FIG. 1 is the most widely used form and is mainly used for a door made of wood for indoor use. .
[18] The door hinge 1 is formed by processing a metal member of a thin plate to form a rectangular shape, a plate-shaped hinge plate 11 having a plurality of fastening holes 10 is formed, respectively, each hinge plate 11 Is freely fastened through the hinge pin (12).
[19] As shown in FIG. 2, the door hinge 1 is fixed to the door 2 and the other side is mounted to the door frame 20 so that the door 2 can be opened and closed smoothly. 1) The assembly tolerance of each hinge plate 11 and the hinge pin 12 maintains a loose tolerance for the smooth opening and closing of the door, so that the door 2 can be easily opened and closed even with a small external force. It was.
[20] However, due to the smoothness of the door hinge (1) when the excessive external force due to the wind or carelessness of the user acts to cause a sudden closing phenomenon, a part of the body between the door 2 and the door frame 20 is injured. Frequent safety accidents occur frequently, causing a great deal of noise in the door operation by friction, causing inconvenience to people around you and others.
[21] Thus, various types and structures of door shock absorbers were devised to suppress the sudden closure of sliding doors, but the structure was complicated and the construction, maintenance and repair were difficult. The problem is that its effectiveness is low.
[22] Therefore, the present invention was created to solve the above problems, and is configured to prevent the sudden closing phenomenon of the door as a shock absorber using the hydraulic pressure generated by the fluid and orifice action through one side of the door hinge to facilitate the angular movement of the door. Its purpose is to improve construction, maintenance and repairability by simplifying and to increase user's convenience.

[25] Door cushioning device 3 of the present invention for achieving the above object is composed of a case (30) forming a cup-shaped as shown in Figures 3 and 4 and a cover 31 for closing the open side thereof. In addition, the case 30 is connected to the diaphragm piston 40, the diaphragm piston 40, and the door hinge 4 that generate a hydraulic pressure through an orifice action of a fluid, including a fluid for generating hydraulic pressure, in the case 30. A buffer pin 50 is provided in the through hole, and a spring 60 for restoring the diaphragm piston 40 is accommodated.
[26] The case 30 is a hollow cylindrical, as shown in Figure 4 is formed on one side with a flange 33 having a plurality of fixing holes 32 on the circumferential surface, the diaphragm piston 40 in the inner diameter of the flange 33 In addition, a plurality of stepping holes 34 are provided to settle the disc shaped cover 31, and a plurality of fastening holes 35 for fixing the cover 31 are formed at the stepping step 34 located at an edge thereof.
[27] The diaphragm piston 40 placed inside the case 30 to generate hydraulic pressure has a diaphragm 41 that is relatively easy to deform and a cylindrical slider 42 that facilitates orifice action of the fluid. It has a combined configuration through the fixing means 43, such as.
[28] In addition, the diaphragm 41 is disposed on the step 34 formed at one end of the case 30, and the diaphragm 41 is disposed inside the case 30 including the flow of the diaphragm 41 through the cover 31 to the outside thereof. Promote airtightness of the filled fluid.
[29] In addition, the actuator 42 combined through the diaphragm 41 and the fixing means 43 forms a constant gap (gab; 44) between the inner diameter of the case 30, and the fluid through the standard of the gap 44. The hydraulic pressure of the can be adjusted, and further interposed between the circumferential surface of the case 30 and the spring (60) required for the restoring after the buffering action of the diaphragm piston (40).
[30] The buffer pin 50, which is connected to the diaphragm piston 40 configured as described above and is provided through the door hinge 4, is composed of the head 51 and the body 52 to form a 'T' shape. The head 51 is press-fitted to one side of the diaphragm piston 40, the body 52 is configured to penetrate the case cover 31 so that a predetermined length protrudes outward.
[31] Door buffer device 3 of the present invention as described above;
[32] As shown in FIGS. 5 and 6, a bolt is fixed to one rear surface of the door hinge 4, and a portion of the buffer pin 50 protrudes through a through hole formed in the door hinge 4, thereby providing a door hinge 4. One side is fixed to the door (5), the other side is fixed to the door frame (6) is mounted by recessing the inside of the door frame (6) the shock absorber (3) interposed on the bottom of the door hinge (4).
[33] As described above, the door buffer device 3 for the door is opened due to the elastic force of the spring 60 interposed between the case 30 and the diaphragm piston 40 as shown in FIG. 6A in the open state of the door 5. The buffer pin 50 maintains a predetermined length and the door buffer device 3 maintains an initial state.
[34] In this state, as shown in FIG. 6 b), external force is applied to the door 5 by the user, such as wind, and the shock absorbing pin 50 protrudes toward one side of the door hinge 4 due to a sudden closing phenomenon of the door 5. When a normal load is applied, the buffer pin 50 moves to the rear (right side in the drawing) and pushes the diaphragm piston 40 associated with it, and the diaphragm piston 40 receives the fluid filled inside the case 30. By increasing the density by pressing the fluid orifice acts to move the fluid through the gap 44 formed on one side of the cooperator 42, a constant hydraulic pressure is generated in the fluid.
[35] As described above, the hydraulic pressure generated in the fluid lowers the moving speed of the diaphragm piston 40 including the buffer pin 50, and in this process, the shock load caused by the sudden closing of the door 5 is canceled by hydraulic pressure to offset the pressure. By doing so, the door 5 is minimized in impact and finally closes smoothly.
[36] Thus, the smooth operation of the door (5) can prevent the safety accident in which the fingers are inadvertently pinched by the inadvertent fingers, especially when closing the door (5) of children and children at home, furthermore, the operation noise of the door (5) In this extremely excluded space, there is an advantage that can suppress the occurrence of noise due to user carelessness.
[37] As described above, the door shock absorber 3 which induces the soft closing of the door 5 through a series of processes is removed from the case 30 and the load acting on the shock absorbing pin 50 disappears at the same time as the door 5 is opened. The diaphragm piston 40 includes the diaphragm piston 40 including the buffer pin 50 to be restored by the elastic force of the spring 60 interposed between the diaphragm piston 40 and the fluid distributed over the entire interior of the case 30. Keep it.
[38] As described above, the shock absorber for the door of the present invention can simplify the configuration through the diaphragm piston and the fluid to improve the use and construction, and because the mounting part is recessed inside the door frame, the appearance is not only beautiful but also semi-permanent durability. It has the advantage of excellent maintenance and repairability.
[39] In addition, due to the action of the buffer pin protruding to the door hinge is a useful invention that can prevent the safety accident that causes the user's body damage in the sudden closing phenomenon of the door by external force.
