Description of the Invention: [Technical Field] The present invention relates to a hinge, particularly for a furniture, having a hinge portion that can be fixed to a door or a flap that is pivotable via at least one lever The rotation is supported on one side, wherein the side portion is held on a mounting plate, and the mounting plate can be mounted on a specific one, wherein the chain has at least one closing spring to extend the hinge portion in a stretching range The inner pre-stressing is to a closed position, and the chamber is provided with an open spring, and the hinge portion is prestressed in an open direction in an open direction. [Prior Art] EP 1 7 1 1 674 discloses a hinge having a side portion that can be fixed to the body and a hinge portion that is supported in a pivotable manner. There is a spring supported on the bar # mechanism to make the key portion (4), which moves the hinge portion in an open range to the open direction, and cannot prevent the movement of the key = cyanine (4) the force is out of control - until one The maximum open door is placed at t. On the other hand, a heavy-weight door can only be moved to a lesser or slower position: Release: This makes it more difficult to cooperate with a snap-in mechanism to lock the door member in a closed position. SUMMARY OF THE INVENTION It ensures the purpose of opening. One of the features of the present invention Accordingly, the object of the present invention is to provide a hinge, and can be easily operated, and can be used in conjunction with different hinges for the purpose of utilizing the patented scope 1 201139825 hinge. According to the invention, the hinge has at least one closing spring that prestresses the hinge portion to a closed position within a stretched range, and at least one open spring is provided to pre-stress the hinge portion in an open direction in an open direction. The closing range overlaps at least partially with the open range, such that the door from the closed or flipped position # ΓOpen spring"# high stress is relieved by the tension spring, so the opening process can be more evenly extended to a desired opening The angle is up. This range of angles that contribute to opening can be adjusted on the "opening spring". Of course, the open spring can be adjusted to be neutral, so that the chain is closed with its closing spring and only the action of the door spring is implemented. This combination of the closing cam and the open spring can also be used in different ranges. For example, for automatic stretching, this action can help open when it reaches a certain open position of the hinge. In addition, the open spring can be adjusted using a pressure point mechanism such that a door or flap is pressed to a predetermined open position, such as at 90. The opening angle. According to another design, the spring force of the open spring and/or the closing spring can be adjusted. Thus, when the two springs and the spring force they cause are heavy, the spring force is adjusted. In addition, the range of action of each spring can be adjusted. Preferably, in the in-closed position, the open spring prestresses the key portion in the opening direction, and the spring force of the open spring is greater than the & spring force of the tension spring. In this case, for example, a snap-in mechanism is provided to fix the hinge portion or a member connected thereto in a closed position. These snap-in mechanisms are used for doors without handles (they release the latch by pressing the door in.) The open spring then presses the door a range of angles. For example, the 201139825 open spring should be designed to compress a 4-yellow type. For example, in the form of a coil spring, it can be accommodated in the hinge portion. The foot spring is recognizable and the retaining edge is provided. The 'open spring can be wound around the linearly movable guiding element, which can be supported to be movable in one turn. Package 3 - pin, ^ P ^ t ik m , so it is ensured that the guiding element is used for good linear guidance, and the Λ" 0 is not used as an internal guide, but also a tubular external guide. In order to make the hinge structure tight, the guide Αβ , ^ ^ 忑 guides one side of the guide member to support the side ' and the opposite side supports a rotatable manner, and the steering member The support 70 is rotated when the hinge portion is rotated in the hinge portion. Thus, the length change of the guiding mechanism from the e-guide 7 can be optimally adjusted by the rotation of the steering member. The re-guided element can also be fixed to the steering element. The position is not changed to change the spring characteristic accordingly. According to a preferred embodiment, the open elastic and the stretched elastomer are adjusted such that the hinge = in an open range (from any angle to a maximum (1).) Open side: The ideal is 25. Because the door can swing into the space without interference, 'this aspect is sufficient. For example, when the plate is carried straight, the door can be pressed by hand. ' lL ^ ° This is the function of the hinge to pivot the door at a wide angle range after the latch is released. In addition, a combination of the two oppositely acting cartridges can be used to preset an equilibrium position. Depending on the size of the door and the size of the door, the door tends to swing to the same opening angle 'where the opening angle can be adjusted with an open spring. In order to optimally adjust the spring force of the open spring and/or the closing spring', at least - Adjust the components to adjust the range of the open spring. Here the 'open spring can also be taken from the hinge when necessary, so the 201139825 hinge can be easily converted into a hinge with only one closed spring. In addition, the hinge can be provided with a damper without an open spring, so that it has great flexibility. The present invention will be described in detail below with reference to the accompanying drawings. [Embodiment] A hinge (1) includes a hinge portion (2) fixed to a door (3) of a raft or another member. The can hinge (2) is pivotally held on one side (4), side ( 4) fixed on a specific (6) or a other component by a mounting plate (5). The side portion (4) can be oppositely used by a first adjusting mechanism (35) and a second adjusting mechanism (36). The movement of the mounting plate (5) allows the door (3) to be adjusted relative to the position of the home (6). The adjustment mechanism (35) (36) can be used to move the side (4) in two or three different directions. alignment. The hinge portion (2) is rotatably supported on the side portion (4) by means of a "portable lever" and a "guide lever" (8), wherein the carrying lever (7) is rotatably connected via a The shaft (11) is supported on the hinge portion (2) and supported on the side portion (4) via a shaft (丨2). The guiding lever (8) has a cantilever (Ausleger, English: cantilever) (13) adjacent to the shaft (12), and a rotating shaft (14) of a lever (15) is formed on the cantilever (13). The opposite end of the lever (15) is rotatably supported on a shaft (16) of a steering member (17). The steering member (17) is supported on the side portion (4) about a rotating shaft (18). The steering element (17) comprises a pin (19) which is coupled to a guiding element (2). Here, the pin (19) and the shaft (16) are provided on the opposite sides of the rotating shaft (18). The guiding element (20) comprises a pin portion (21) which is connected to the pin (B〇lzen, English: 201139825 bolt) (19) and has a pin (SHft, English: pin) (23), the pin It is housed in a weir (24), and in addition, the pin portion (21) has a radially protruding ring (22), and an open spring (27) is supported on the ring, which is held in the pin portion by a coil spring (21). Between and 匣 (24). An annular projection (25) is formed on the crucible (24), and one end of the opening spring (27) is supported on the projection (25). The open spring (27) presses the hinge portion in the open direction via the deflecting element (17), the lever (15) and the guiding lever (8) which are connected in the middle. Conversely, the closing spring (3〇) acts in the closed position. The closing spring (3()) contains the middle winding section leg (3 1 ) and the leg is supported on a pin (32). Further, the second leg (33) of the tension spring (30) is supported on the shaft (18) or on another member to prestress the chain portion (2) in the closing direction. Further, the side portion (4) is fixed to the mounting plate (5) by a hook (38) and a spring-stressed mounting hook (37). Figure 2 shows the door (3) in a slightly open position. By dragging the door (7): the pin (23) is partially pulled from the cymbal (24), thus opening the load-discharging portion of the ejector (9). Conversely, the 'tension spring (10) pivots, and the legs (3 and (33) are correspondingly rotated by an angle to each other. By the further opening movement of the door (3), the position shown in Fig. 3 can be achieved. At this position, the door (3) opens about 90. The open magazine (27) is more elongated," the middle lock is pulled out more from the H (24), so the load of the open bomb is further increased; When Η (3) moves in the closing direction, the open bullet (7) must be shrunk. However, starting from the 4 opening angle of the door (3), the stretching elastic (9) = the initial action, and the door is pressed to the closed position. However, the amount of turns of the open spring (9) is greater than the force of the tension spring (30), so that the door (3) is pressed in the open direction at a predetermined angle range (for example, Θ201139825 between 关闭. (closed position) and 50. In the closed position, the 'door (3) is held by the engaging mechanism not shown, and the engaging mechanism can release the latch by pressing the door (3). In Fig. 3, a ring is formed on the cymbal (24). The end section (25,) has a "running bevel" (28) formed thereon. Thus, the guiding member (2) can be easily attached to the pin (26). The coordinate diagram is a relationship between the spring force of the coupling door and the opening angle of the hinge portion (2), and the spring force of the open spring decreases as the opening angle becomes larger, and can be ignored when the opening angle is from 55. The spring (3〇) is used to generate a moment in the closing direction on the hinge portion (2), wherein the maximum torque is generated in the range of 15 to 30. The torque is also negligible from about 55. Thus, The hinge portion (2) causes a moment of engagement, which is used to press the hinge (2) up to an angle D (in the range between 15 and 25), and the hinge portion (2) In the range of D and about 55., it is pressed in the closing direction. If the door is closed, until the point D, it is kept closed by the resultant force of the ridge, and there is only one 〇. In the closing range, the user has to overcome the combined force of the opening. Point D can be adjusted in a wide range by using an open spring (27) and a closing spring (3〇) for different applications. Displaying the guiding element (20), wherein the spring of the open spring (27) The opening spring (27) is supported on the pin portion (21) of the protruding ring (22), and on the opposite side, between the annular protrusion (25) and the end of the open spring (27) With-ring (4G), for example - spring ring, so the open spring (27) is compressed more tightly, and the length is shortened 'so that a large spring force acts on the 201139825 pin section (2 1) and The additional mechanical transmission element obtains the hinge portion (2) in a larger direction with a larger moment. Figures 6A and 6B show another possible adjustment of the guiding element (2〇), wherein the annular projection at the 匣 (24) (25) having a first passage (41) for receiving the pin (26) and a second passage (42) for receiving the pin passages (41) and (42) § at an angle to each other, particularly at right angles The depth X of the channel (4丨) is larger than the channel (42). Here, '匣(24) can be deflected by 90. Mounted on the pin (26), the deeper channel (41) or channel (42) can be selectively engaged with the pin (26). Correspondingly, the distance between the annular projection (25) and the projection (22) on the pin portion (21) is shortened or lengthened by the value of X. Thus the length L1 of the open spring (27) and the spring force are correspondingly changed accordingly. . Another embodiment for varying the spring force is shown in Figure 7, wherein a thread (44) is formed in the region of the crucible (25) adjacent to the disc-shaped projection (25). An internal threaded projection (25) is provided on the thread (44). The thread (44) is provided with an adjustment wheel (45) having an internal thread which is axially adjustable by rotation. One end of the open spring (27) is supported on the adjusting wheel (45), and the opposite end is supported on the annular projection (22) of the pin portion (21). Figure 8 shows another possible way of adjusting the length of the open spring (27), where a threaded section (46) is formed on the pin portion (25), on which an internally threaded adjustment wheel (22' is provided. ). By turning the adjustment wheel, an axial adjustment is made, so that the open spring (27) can be compressed or relaxed by the adjustment wheel (22). Here, the length between the pin (19) and the pin (26) remains constant. Of course, the adjustment mechanisms shown in Figs. 5 to 8 can also be combined with each other, and other adjustment mechanisms can be provided to change the prestress of the open spring (27). 201139825 In addition, the force of the 'tension spring (30) can be adjusted by the relevant adjustment mechanism.
