Secondly, the movement of the fourth link is restricted due to the engagement of the second recess and the first pressing member. Therefore, the fully opened door can be prevented from being moved in the closing direction due to vibration or the like. Unstable. While referring to Figures 3 and 4 above, the above-mentioned matters are 'i.e. as shown in Figure 3, even if the auxiliary plate member HB is removed', and even there is no% 2 squeeze member M2, or as It is the same as shown in Fig. 5 or Fig. 6. As will be described later, the case where the auxiliary plate member and the second pressing member M2 are attached is different from the case where the door is automatically pulled in the fully closed direction and suspended. At a predetermined position on the inner side of the auxiliary plate member HB, a notch portion TA 'provided at the door-side base portion DB can be engaged and a disengaged engagement portion TA constitutes a removable auxiliary plate member. In addition, a mountain-shaped convex portion TB serving as an engaging portion is provided at a predetermined position on the front side, and in a state of being mounted on the door-side base portion, if the open side of the storage space SP is made up and the bottom side is made down, The auxiliary plate member is attached so as to extend in the vertical direction. The upper side of the convex part KK means a direction that is almost orthogonal to the surface of the auxiliary plate member; and it forms a steep angle, and the lower side YK forms an inclined angle. The height dimension of the convex portion is equal to or less than the length of the major axis 3 (major axis diameter) of the through-hole P3BH provided in the second pressing member M2 described above minus the diameter of the pin P3B.

Description of the invention (J) Before the door is completely closed, if it is at about 25 degrees, the position is described by Generally, the door of the mechanism starts to close automatically. However, before the door is completely closed, for example, at a position about 5 before the door opening angle, the second pressing member M2 pulls the steep inclined surface KK of the convex portion, and the movement of the door is suspended. 'If the door is pushed with a predetermined force or more, the second pressing member retracts against the force of the coil spring R, and is disengaged from the engagement with the convex portion. As a result, the door can be completely closed. The second pressing The front end of the component can be disengaged from the engagement with the steep inclined surface of the convex portion by a predetermined force to form an approximately elliptical shape or Objects are smooth and thin. By engaging the convex part, the door's movement can be suspended to prevent the door from coming into strong contact with the frame to produce a loud sound. After that, in order to surpass the convex part, the predetermined force is used. When the door is pushed open, because the operating angle of the door is small (about 5 degrees), a large collision sound does not occur. For example, referring to FIG. 6, when the door in the closed state is opened, the second pressing member M2 is located at the convex portion. On the lower side, at this time, it is in contact with the gently inclined surface 但 Κ, but because the inclination is gentle, there is no great resistance, and the fourth link can surpass the convex portion TB. Therefore, the door opening operation does not cause a bad situation. However, as shown in FIG. 3, the state switch can be removed from the auxiliary plate member according to the user ’s preference if it is required to use this mechanism. Also, in the above description, the surface CS of the bearing portion JB is arc-shaped, at the second place Recesses KI, KK2 are provided, but the fourth chain link is not provided. The pin P4B can be used as a pivot to rotate. On the fourth chain link, only the second compression member M2 is used as the spring mechanism.弹 The mechanism pressed by the spring R, on the other hand, on the door side base DB The side can also be used as a hinge device with the convex part TB described. __- __18___ Appropriate paper size.

Description of the invention (丨 P) This The situation is that when people want to close the door, before the second is fully closed, the second pressing member and the convex part are engaged, which can at least reduce the force of closing the door. If the closing force is appropriate, the force of the door is suspended, and then pushed again, That is completely closed. Even if it is any of them, it has the effect of preventing the door from coming into contact with the edge of the frame and producing a loud sound. The convex portion TB is not formed on the freely detachable auxiliary plate member, and may be formed by integrally protruding inside the door-side base portion DB. In addition, the hinge device described above is usually provided with two upper and lower positions for the door. However, in this case, when the gap between the left and right doors is uneven in the upper and lower positions, as described above, by using another screw N2, the The gap can be adjusted by adjusting the position of the lower member of the frame-side base. In the above description, furniture and the like are described on the premise that they are made of sheet metal, such as steel, but they are the same even if they are wooden furniture. [Effects of the Invention] It is clear from the above description that according to the present invention, it is possible to provide a hinge device capable of more effectively using the storage space of furniture and the like.
