[Prior Art] The door opening and closing device is generally provided with a frame-side mounting structure attached to the inner surface of one side of the frame formed in a box shape, and is attached to the openable and closable frame. a door-side attachment member on the back surface of the door opening in the front surface; and a 'first and second link. One end portion of each of the first and second links is rotatably coupled to the frame side mounting member, and each of the other end portions is rotatably coupled to the door side mounting member. Therefore, the frame-side attachment member, the door-side attachment member, the first link, and the second link are configured to form a four-node link mechanism, whereby the four-node link mechanism door is coupled to close the frame. Opening and closing between the position and the open position. (Problems to be Solved by the Invention) In the above-described conventional door opening and closing device, the fan-side mounting member, the i-th link, and the second reading member are provided. The door system forms a parallel link mechanism. Therefore, the link mechanism is in a posture when it is maintained at the closed position, and thus, for example, the door is placed in the posture of the child. The field door is moved up and down in the up and down direction. When the door is moved in the open position 097142338 200930880, the upper end of the door will protrude greatly from the frame upwards, and when the door is opened and closed in the left and right direction, the left and right ends of the door will be greatly moved from the frame to the left and right. In order to solve the above problem, the ith aspect of the present invention includes: a frame body having an open box shape at the front portion; and a door leaf, a fan The opening and closing device is provided on the frame in an openable and closable manner; the above (10) is in a closed position in which the opening portion of the frame body is closed along the front surface portion of the frame body; and the door leaf is completely The door opening is located at one end side of the center of the frame, and the door leaf is opened at an open position of the opening of the frame body located at the other end side; and the movable device is such that the special emblem is μ, +. When the day β is that the door leaf is located at the open position, the door-end portion is inclined away from the front portion of the frame body toward the front from the front end portion. The door leaf is tilted. In this case, the door leaf is closed. One of the above-mentioned (four) portions facing the end of one of the frames, when the light is from the closed position toward the open position to the predetermined intermediate position, from the other end side of the upper body On the other hand, the other side is separated from the frame body and moves, and the movement of the door leaf from the intermediate position to the opening position of the opening position is from the end side of the frame body (4). In order to solve the above problems, a second aspect of the present invention includes a mounting member and is attached to a box-shaped housing having an opening at a front portion; and, = 09 7142338 200930880 The fan side mounting member is attached to the first and second links of the opening of the frame, and one of the ends is rotatably centered on the mutually parallel ... and the ? The other end portion of the frame body is connected to the first and second rotation axes parallel to the i-th and second rotation axes, and the middle and the right rotation axis are rotatably coupled to the door leaf side. The second rotation axis is disposed from the opening of the frame body [when the 〇-swing axis is at the closed position = the other end of the frame is opposite to the door-to-door portion] the first rotation The shaft is disposed on the upper end side by the second crane shaft, and the third rotation shaft is disposed on the one end side of the upper=fan by the fourth swinging gamble. In the door opening and closing device, the 1st, the /] side is installed. The member, the door-side anti-seismic member, and the four-node link mechanism of the two-body 旋 are configured to satisfy the moving distance ratio of the third rotation when the fan is rotated from the closed position to the upper position. The moving distance in front of the fourth rotation axis is more; In this case, it is preferable that the fourth link mechanism is configured such that the third rotation axis is configured to satisfy the condition that is often located before the fourth rotation axis regardless of the rotation position of the door leaf. Further, the length of the distance between the second and second rotation axes plus the distance between the third and third rotation axes is set to be longer than the third and fourth rotation axes _ plus the second and fourth The length of the rotation _ is longer, and the door 097142338 5 200930880 fan sequentially arranges the second rotation axis and the third position on the line between the closed position and the open position, and the third rotation The above-described four-node link mechanism is constituted by the shaft, and the above (the effect of the invention) is based on the (4)th release position of the present invention having the above-described characteristic configuration, that is, the door leaf is located at the frame], the fan is located at the opening _, and the door is largely separated. Tilt, so the face: the direction toward the one end, the other end of the body can be made smaller. When the projection of the one end of the one-piece projection from the frame protrudes to the open position according to the second state position of the present invention having the above-described characteristics, the movement of the fan from the fifth rotation to the front β of the fourth rotation axis is caused. When the door is in the upright position, the door leaf is longer: therefore, it is located in the closed ❹ and will be inclined, so that the W of the door leaf in the open position greatly leaves the front side of the frame from the front end of the frame. And tilted. Therefore, the same as the first aspect, the amount of protrusion of the door-end portion from the frame can be made small. [Embodiment] The following is a description of the best form of the invention of the W-type Langshi County. Fig. 1 to Fig. 12 show an embodiment of the storage device of the present invention.

When the door 3 is in the open position, as shown in Fig. 5, the entire door leaf 3 is located on the upper end side (one end side) of the center of the frame body 2 in the vertical direction of the Z. Thereby, the door leaf 3 can be opened to open the opening portion of the lower side (the other end side). Further, when the door leaf 3 is in the open position, the upper end portion of the door leaf 3 is largely inclined away from the front end portion with respect to the front side of the frame body 2. In the door opening and closing device 4, the door leaf 3 is moved from the closed position to the open position as described above, and i are provided between the frame 2 and the left and right sides of the door 3. The two door leaf devices 4 and 4 provided on the left and right sides are configured to be bilaterally symmetrical. Therefore, only the door leaf device of the side is described. The door closing device 4 has a tow side mounting member 4 (four) side mounting member 42, a second link 43 and a second link 44. The frame side mounting member 41 is made of a metal plate material, and is attached to the inner side surface of the left and right sides of the frame 2 and close to the opening portion. The mounting member 41 is mounted on the frame side, and the first, the _ 2 rotating shaft 45, the * □ 2 rotating shaft 45, and the * connecting rods 43 and 44 of the horizontal 097142338 7 200930880 are rotatably connected to the second 2 邛^知邛 (hereinafter referred to as the base end portion, and the other end portions of the first and second flails 43, 44 are referred to as the front end portion). The second link: 3, the second front end portion is rotatably coupled to the closed fan side mounting member 42 by the first tilting shafts 47, 48 which are parallel to the first and second rotary pomelo members 45, 46. ^This fine is made up of the frame side mounting member 4 (the door leaf side mounting member commits the first 1, Φ: 2 connection # 43, 44 to form the four-node linkage mechanism RL this - four-section linkage mechanism R, 俾姑1 The frame-side attachment member 41 is fixed to the fixing system of the frame body 2 by the field. The p-door side plate member 42 is attached to the face 3a by the coupling tool 6. The coupling device 6 is like It is known to be used in such a door opening and closing device = a moving hinge, etc., and since it is not the focus of the present invention, it is erected, but it is formed with respect to the door side mounting member 42, the fan' The position of the attack can be slightly adjusted in the up, down, left, and right directions, and the front and rear directions of the door 3 can be finely adjusted to the frame 2. The busy body side mounting member 41 and the first link 43 are One end portion of the pneumatic spring A moving spring 7 is rotatably coupled to the frame side mounting member 41 by an axis '49 parallel to the first rotating shaft 45. Pneumatic spring 7 - 碥° The cymbal is rotatably coupled to the movable member 8 provided on the first link 43 by a shaft 50 parallel to the shaft 49. The pneumatic spring 7 is the door leaf 3 When the position is between the closed position and the predetermined neutral position on the open position side of the predetermined distance, the first link 43 is rotated clockwise in the figure 097142338 8 200930880 = 丄 and the door 3 is further From the open position side toward the closing position between the closed position and the neutral position, the door leaf 3 is automatically moved to the closed position when the door leaf 3 is moved between the closed position and the neutral position from the open position side toward the closed position side according to its own weight. When the position is in the neutral position, the shafts 49, 50 and the first rotating shaft are in a straight line. Therefore, the pressing force of the pneumatic spring 7 does not have the effect of rotating the dusting force on the first link 43. When the door 3 When the self-closing position side is more than the neutral position toward the open position side, the service spring 7 is rotated counterclockwise as shown in FIG. 2 to press the first link 43 and apply pressure to the open position side of the fan 3. 'The pressure applied to the pneumatic spring that presses the side of the open position of the fan 3, the force of the door leaf 3 moving from the neutral position toward the open position to the predetermined equilibrium position is the force that moves the door leaf 3 toward the closed position side by its own weight.

In addition, when the door leaf 3 is over the equilibrium position from the closed position side to the open position side, the pneumatic ridge 7 of the door leaf 3 is pressed toward the open position side. The applied pressure is stronger than the force of the door 3 to the closed position side. Therefore, when the door leaf 3 exceeds the equilibrium position, it automatically moves to the open position. Further, the movable member 8 can adjust the rotation of the first link 43 of the pneumatic spring 7 by adjusting the position of the movable member 8 in the direction in which the first rotary shaft 45 and the shaft 50 are coupled: The pressure, and even the pressure applied to press the door leaf 3 from the closed position side toward the open position side can be adjusted. The pneumatic spring 7 is provided between the frame side mounting member 41 and the second link 44. 097142338 9 200930880 Further, instead of the pneumatic spring 7, other pressing means such as a tension spring or a compression magazine may be used. As shown in Fig. 9, the both ends of the reinforcing plate 9 are attached to the first rotating shaft 45 and the second rotating shaft 46, respectively. Thereby, the reinforcing plate 9 can reinforce the frame side mounting member 41. As shown in Fig. 11, the decorative cover 10 is attached to the frame side mounting member 41. Thereby, the decorative cover 10 can be shielded so that the frame side attachment member 41, the base end portions of the first and second links 43, 44, the pneumatic cymbal spring 7, and the reinforcing plate 9 are as small as possible from the outside. An abutting member 31 is provided at a lower end portion of the door leaf 3. When the abutment member 31 moves from the open position side to the closed position, the abutment member 3 comes into contact with a stopper (not shown) provided on the casing 2. Thereby, the closed position of the door leaf 3 is restricted. On the other hand, as shown in Fig. 5, when the door leaf 3 is moved from the closed position side to the open position, the abutting member 31 comes into contact with the second link 44. Thereby, the open position of the door leaf 3 is restricted. As shown in Fig. 12, a bracket 11 is fixed to the first link 43, and a damper mechanism 12 is provided on the bracket 11. The damper mechanism 12 has a cylinder 12a; the base end portion of the #12b' is movable in the axial direction thereof and is accommodated on the cylinder 12a', and the end portion protrudes from the cylinder wa. When the rod 12b relatively moves in the direction of entering the inside of the cylinder 12a, the damper mechanism 12 has a function of suppressing the moving speed to a low speed. The cylinder i2a of the salt shaker mechanism 12 is movably provided on the bracket 11 in the axial direction. In addition, the rod 12b is fixed in the bracket 11 and, therefore, 097142338 200930880 In the damper mechanism 12, the cylinder 12a actually moves relative to the rod 12b. As shown in FIG. 1, when the door leaf 3 is moved from the open position side toward the closed position side and is located just before the predetermined distance from the closed position, the cylindrical jaw 2a is abutted against the abutment portion provided on the frame side mounting member 41. 41a. As a result, the rod 12b relatively enters the cylinder 12a while the cylinder 12a moves. Therefore, the movement of the cylinder 1 from the abutting portion 41a to the closing position of the door leaf 3 can suppress the moving speed to the closed position side of the door leaf 3 to a low speed. Therefore, the abutting member ❹ 31 does not collide with the stopper of the casing 2 at a high speed, and the impact due to the collision can be prevented. Further, as shown in FIG. 4, when the door leaf 3 moves from the closed position side toward the open position side and reaches the lion's open position before the predetermined turning direction, the round 枉 is positioned inside the wa and the cylinder 12a is moved from the abutting portion 44 to the inside.

Further, the first and second rotations 097142338 200930880 are disposed on the upper end side of the center in the upper and lower directions of the casing 2, and the 'third and fourth rotation shafts 47, 48 are disposed in the closed position. The lower side of the center of the door 3 in the vertical direction. Therefore, in addition to the distance between the i-th rotation axis 45 and the third rotation axis 47 and the distance between the second rotation axis and the fourth rotation axis 48, when the door leaf 3 is located In the open position, the lower end of the door leaf 3 can be positioned as far as possible. Further, the four-node link mechanism R is moved between the door 3 and the open position from the closed position, and the third rotary shaft 47 is often located above the fourth rotary shaft 48, and is configured to satisfy the third position therebetween. The condition that the rotation shaft 47 moves greatly forward than the fourth rotation shaft 48. In order to achieve this, the four-bar linkage r is a four-node linkage other than a parallel rod. That is, as shown in FIG. 当, when the distance between the centers of the first rotation shaft 45 and the second rotation shaft 46 is set as the first inter-axis distance L1, the first rotation shaft 45 and the third rotation shaft are caused. The distance between the centers between 47 is the second inter-axis distance L2, and the distance between the centers of the second rotation shaft 46 and the fourth rotation shaft 48 is defined as the third inter-axis distance L3, so that the third rotation shaft 47 is provided. When the distance between the centers of the fourth rotation shaft 48 and the fourth rotation axis 48 is the fourth axial distance L4, the first to fourth axial distances L1 to L4 can be defined under any of the conditions L1, L4, L2, and L3. . Further, in this embodiment, the four-node link mechanism R is configured to satisfy the following conditions. 097142338 12 200930880 L1>L4 L2> L3 L1 + L2> L3 + L4 - Further, the distance between the second and third axes L2, L3 is set to be larger than the distances between the first and fourth _ axes L1, L4 . Further, when the door leaf 3 is in the closed position, the distance between the first and second rotation shafts 45 and 46 in the front-rear direction and the vertical direction is greater than the third and fourth rotation shafts 47 and 48 in the front-rear direction and the vertical direction. The distance is longer. Further, when the door leaf 3 is in the closed position, the first rotation axis 45 is located later than the third rotation axis 47, and the second rotation axis 46 is located later than the fourth rotation axis 48. When the door leaf 3 is coupled to the casing 2 by the door opening and closing device 4 having the above configuration, as shown in FIGS. 1 to 6, the third rotating shaft 47 is moved from the closed position toward the open position, and the third rotating shaft 47 is closer to the fourth rotating shaft. 48 moves greatly forward. In other words, the distance between the third rotation shaft 47 and the fourth rotation shaft 48 in the front-rear direction becomes larger as the movement of the door leaf 3 from the closed position toward the open position becomes larger. As a result, the upper end portion of the door leaf 3 is inclined away from the front end 2a of the casing 2 toward the front side greatly away from the lower end portion. Further, as the door leaf 3 is opened from the closed position, the inclination angle of the position side is also increased. When the door leaf 3 moves further toward the open position side and reaches the predetermined intermediate position shown in Fig. 4, the second, fourth and third rotation axes 46, 48, 47 are arranged in a straight line. The door leaf 3 is moved from the closed position to the intermediate position, and the upper end portion of the door leaf 3 moves forward on the one hand and upwards on the other hand. However, when the door leaf 3 is moved further toward the open position side, the 帛4 rotation shaft 48 is positioned to be larger than the connection line connecting the second knob 46 and the third rotation sleeve 47! The side of the shaft 45 is rotated, and the upper end of the door 3 moves toward the front side and moves downward as the side moves toward the open position of the door 4 3 . As a result, the increase ratio of the inclination angle of the fan 3 is also increased with respect to the predetermined turning angle of the second link 43, 44. Therefore, the door leaf 3 can increase the inclination angle of the door leaf 3 when it reaches the open position. ❹ When the door leaf 3 is moved to the open position, the door leaf 3 is tilted, so that the amount of protrusion of the upper end portion of the door leaf 3 protruding upward from the frame 2 can be suppressed to be small. Further, the present invention is not limited to the above-described embodiments, and may be modified as appropriate without departing from the scope of the invention. For example, in the above-described embodiment, when the door leaf 3 moves from the closed position toward the open position side, the moving distance of the third rotating shaft 47 to the front is determined to be a forward movement of the fourth rotating shaft 48. The distance is longer, and when the door 3 reaches the open position, the full moving distance of the third rotating shaft 47 to the front is longer than the full moving distance of the fourth rotating shaft 48, and the door is opened from the closed position. The position moves only between the predetermined strips, and the movement of the door leaf 3 from the closed position toward the open position side is such that the moving distance of the third expanding shaft 47 to the front is configured to be longer than the fourth rotating shaft 48. It can be shorter. SHIPPING (Industrial Applicability) 097142338 14 200930880 The present invention can provide a relatively large space in front of the opening of the casing, and can be applied to a storage device having a narrow space on the side of the casing. The opening of the temple is very open.
