That is, the bent portion 4b of the front link 4 is bent in the direction opposite to the bent portion 4a. Then, in a state where the storage body 2 is most pulled down from inside the outer box 1 to the lower front part of the outer box 1, the upper edge of the front link 4 is lower than the lower edge of the rear link 5 as shown by the imaginary line in FIG. , And the inner corner of the angled corner of the bent portion is set to face the rear link 5 side. The front link 4 and the rear link 5 are displaced in the lateral direction (left and right directions in FIGS. 4 and 5) so as to rotate in different vertical planes parallel to each other. [0010] As shown in Fig. 8, the housing 2 has a plate 14 having a bottom portion and a back portion provided between the left and right side plates 13 facing each other, and is fixed. The front and upper portions are open. FIG.
As shown in (1), a shaft support plate 15 is fixed to the upper portion of the outer surface of the side plate 13 of the storage body 2 with a fixing tool such as a screw.
The shaft support plate 15 is made of a metal plate, and has an upper shaft portion 16 protruding from a rear portion of an upper portion of the shaft support plate 15 toward the side, and a projecting length longer than the upper shaft portion 16 at a lower front portion. A long lower shaft portion 18 protrudes toward the side. Then, as shown in FIG. 11, a hole formed at the upper end of the front link 4 is rotatably fitted into the lower shaft portion 18 and attached. The hole formed at the upper end of the rear link 5 is connected to the upper shaft portion. 16 so as to be freely rotatable. As shown in FIGS. 9 and 13A, the lower end of the front link 4 and the lower end of the rear link 5 are rotatably supported at the lower part of the inner surface of the side plate 19 of the outer box 1. The shaft support block body 20 is attached. The attachment of the pivot block 20 to the side plate 19 will be described later in detail. The shaft support block body 20 is integrally formed by die casting of aluminum. The inner surface side of the shaft support block body 20 (that is, the side plate 1)

3 and an upper block 2 provided with a damper storage recess 25 for storing and mounting a damper composed of an oil damper 24.
6 are integrally connected to each other by a connection block 27 that is inclined obliquely to form a main body. Then, as described later, the spiral spring 21 and the oil damper 24 are housed in the damper housing recesses 22 and 25, respectively, and the lower ends of the front link 4 and the rear link 5 are attached by shafts, and are attached to the side plate 19 by screws. By mounting the pivot block 20, the pivot block 20 serves as a mounting member for mounting a damper,
It has a role as a cover material to cover, and a role as a member for supporting the lower ends of the front link 4 and the rear link 5. A self-supporting leg 28 hangs downward from the inclined connecting block 27, and the lower end of the self-standing leg 28 and the lower block 23 are at the same level. When the support block body 20 is attached to the lower part of the inner surface of the side plate 19 of the outer box 1, the lower end of the self-supporting leg 28 and the lower block part 23 are placed on the upper surface of the bottom plate 11 of the box body 1 so that the support block body is mounted. The support block 20 can be self-standing and can be easily mounted on the lower portion of the inner surface of the side plate 19 of the outer box 1. A small positioning protrusion 56 projects forward from the lower end of the front end of the pivot block 20.
When the boss is biased toward the front end of the lower end in the outer case 1, the positioning small protrusion 56 is aligned with the front end edge of the opening of the outer case 1, so that the front and rear of the shaft support block body 20 with respect to the outer case 1 is adjusted. Direction positioning is performed. Next, the mounting of the pivot block 20 inside the side plate 19 of the outer box 1 will be described. 9 and 1
5 shows an embodiment in which the pivot block 20 is attached to the inside of the side plate 19 of the outer box 1. That is, as shown in FIG. 9, a plurality of wood screw insertion holes 60 are provided in the shaft support block 20 so as to penetrate both sides, and one or a plurality of bolt screw holes 61 penetrate in both sides. It is provided as follows. On the other hand, the side plate 19 of the outer box 1 is provided with a retaining hole 64 that opens on the inner surface side. The retaining hole 64 may be a through hole, but a bottomed hole that is opened only on the inner surface side of the side plate 19 so as not to be seen from the outside of the side plate 19 is preferable in appearance. Then, the lower ends of the front link 4 and the rear link 5 are attached to the pivot block 20 (in this case, it is preferable that the upper ends of the front link 4 and the rear link 5 are attached to the pivot plate 15). ), The pivot block 20 is arranged at the front end of the lower inner surface of the side plate 19, the positioning small projection 56 is positioned in accordance with the front edge of the opening of the outer box 1, and a bolt screw is provided inside the outer box 1. The bolt 63 is screwed into the joint hole 61, the tip end of the bolt 63 is inserted into the retaining hole 64 opened inside the side plate 19, and the pivot support block body 20 is held with respect to the side plate 19 in a positioned state. Further, a wood screw 62 inserted from a plurality of wood screw insertion holes 60 provided in the shaft support block body 20 is fixed to the side plate 19. In this way, the bolt 63 is screwed into the bolt screwing hole 61 so that the bolt 63
Is inserted into the retaining hole 64 opened inside the side plate 19, so that even if the wood screw 62 is loosened, the bolt 63 inserted into the retaining hole 64 causes the shaft support block body 20 to Is not dropped from the side plate 19. In this embodiment, one or a plurality of bolts 63 are screwed from the inside of the outer case 1 into the bolt screw holes 61 provided in the shaft support block body 20, and the tips of the bolts 63 are placed inside the side plate 19. Since a simple configuration in which the shaft support block body 20 is inserted into the opened retaining hole 64 is sufficient, it is possible to easily prevent the support block body 20 from falling off at low cost. Further, since the tip of the bolt 63 is inserted into the retaining hole 64 and the support block 20 is positioned and held, it can be fixed by the plurality of wood screws 62. It can be easily and reliably fixed to the position. Of course, after fixing with the wood screw 62, the bolt 63 may be screwed into and the leading end of the bolt 63 may be inserted into the retaining hole 64. A projection 53 for preventing the link from falling down is provided at the upper end of the shaft support block 20, and the housing 2 is housed in the outer box 1 as described later. As a result, the front link 4 hits the link fall prevention protrusion 53 to prevent the front link 4 from rotating rearward, and prevents the storage body 2 from falling backward when the storage body 2 is stored in the outer box 1. A stopper 54 is provided on the side surface of the front lower end portion of the shaft support block body 20, and the front link 4 is moved in the maximum withdrawn state when the storage body 2 is pivoted to the front lower part of the outer box 1 and withdrawn. The front link 4 is kept in the maximum lowered state by hitting the stopper 54 so that the front link 4 cannot rotate downward any more. As shown in FIG. 9, FIG. 10 and FIG. 13 (a), a damper accommodating recess 22 is formed by recessing the inner surface side of the lower block portion 23 below the shaft support block body 20. A hole 29 penetrating in and out is provided at the center of the storage recess 22.
The shaft 30 is inserted into the hole 29, and the lower end of the front link 4 is rotatably supported on the shaft 30 to be attached thereto. A spring damper including a spiral spring 21 is housed in the damper housing recess 22. A damper engaging portion 31 is provided in the damper accommodating concave portion 22, and locked portions 32 are provided at both ends of the spiral spring 21 constituting the damper. The portion 32 is locked to the damper locking portion 31, and the locked portion 32 at the other end of the spiral spring 21 is locked to the split groove 33 provided at the tip of the shaft 30. Thus, the spiral spring 21
When the storage body 2 is pivoted downward from the inside of the outer box 1 forward and downward, the spiral spring 21
The damper is made to be a resistance. Here, simply by locking the locked portions 32 at both ends of the spiral spring 21 with the damper locking portion 31 and the split groove portion 33, the spiral spring 21 is displaced in the axial direction of the shaft 30 and the outer case 1
In some cases, abnormal noise may be generated by rubbing against the side plate 19 or the like, or the locking strength may not be sufficiently exhibited. Therefore, in the present invention, as shown in FIG. The push nut 50 is attached to the shaft 30 on both sides of a portion where one end of the shaft is locked to the shaft 30. As shown in FIG. 13B, the push nut 50 is formed by projecting a plurality of resilient spring pieces 50b on the inner peripheral edge of the ring body 50a. The spring piece 50b is easily attached by being pressed against the shaft 30, thereby preventing the spiral spring 21 from moving in the axial direction of the shaft 30, and causing the spiral spring 21 to move in the axial direction and rub against other members. The generation of abnormal noise due to noise is prevented, and the locking state is maintained at a constant state to secure the locking strength. In addition, a washer 50c impregnated with oil is interposed between the push nut 50 and the spiral spring 21 so as to improve the sliding property of the contact portion with the spiral spring 21 to reduce the friction. . As shown in FIGS. 9, 10 and 13A, a damper accommodating recess 25 is formed by recessing the inner surface side of the upper block portion 26 of the upper portion of the shaft support block 20. A hole 34 penetrating inward and outward is provided at the center of
Is provided. A damper made up of the oil damper 24 is housed in the damper housing recess 25 and is attached to the shaft support block body 20 with screws. A rotary drive shaft 35 of the damper composed of the oil damper 24 is rotatably inserted into a hole 34 of the shaft support block body 20 through a bush 42 containing oil. It protrudes in the direction. The rear link 5 is attached to the rotary drive shaft 35. Here, as shown in FIG. 12 and FIG.
A plurality of screw insertion holes 38a and a plurality of positioning holes 38b are provided at the lower end of the rotary drive shaft 35. A plurality of screw holes 37a and a plurality of positioning bosses 37b Is provided. And the positioning hole 38b
The screw 42 is inserted from the screw insertion hole 38a in a state where the boss 37b is fitted and positioned in the screw hole 37a, and is screwed and fixed to the screw hole 37a. Here, as described above, the positioning holes 3
By inserting the screw 42 from the screw insertion hole 38a and screwing it into the screw hole 37a in a state where the boss 37b is fitted in the 8b and positioned, not only can the screw 42 be easily inserted and screwed, but also When the rear link 5 rotates, the positioning hole 38b and the boss 37b are fitted to prevent the rear link 5 from rotating in the rotational direction between the rear link 5 and the rotary drive shaft 35. The rear link 5 is stably connected to the rotary drive shaft 35 for a long time without loosening the threaded portion of the screw 42.
It can be fixed to Further, the pivot portion at the lower end of the rear link 5 is shifted from the pivot portion at the lower end of the front link 4 in the direction away from the side plate 19 of the outer box 1. Therefore, with respect to the side plate 13 of the housing 2, the pivot portion at the upper end of the front link 4 is located at a position shifted from the side plate 13 of the storage body 2 more than the pivot portion at the lower end of the rear link 5. In addition, the outer side of the shaft support portion of the lower shaft portion 18 that rotatably attaches the upper end portion of the front link 4 to the storage body 2 side is the outermost portion of the storage body 2. And, this lower shaft portion 18
The cap 58 is attached to the shaft supporting portion to cover the outside of the shaft supporting portion. The cap 58 is formed of a flexible material, such as rubber or soft synthetic resin, which is more flexible than the rear part of the door which is attached to the front surface of the outer box 1 so as to be freely opened and closed. In this manner, by attaching the cap 58 to the shaft support portion of the lower shaft portion 18 and covering the outside of the shaft support portion, the door of the outer box 1 can be erroneously opened in a state where the storage body 2 is pulled down to the front lower side of the outer box 1. Even if the door is closed, the back surface of the door hits the cap 58, so that it does not hit the portion rotatably attached to the link storage body 2 and does not damage the back surface of the door.
It has become. When the housing 2 is completely housed in the outer box 1, the front link 4 abuts against the link falling prevention projection 53 provided on the pivot block 20 to prevent the rearward rotation. This prevents the storage body 2 from falling backward when stored in the outer box 1. Then, in a state where the storage body 2 is completely stored in the outer box 1, as shown in FIG. 3, the shaft supporting portion A on the front link 4 is located above and behind the lower shaft supporting portion B, and The upper supporting portion c on the rear link 5 is located above and behind the lower supporting portion d, and a line connecting the supporting portions a and b in a state where the storage body 2 is completely housed in the outer box 1. Is inclined obliquely so that a is located rearward and upward, and the line connecting the shaft supports c and d is obliquely inclined such that c is located rearward and upward, and as a result, With the body 2 completely stored in the outer box 1,
Due to its own weight, a force is exerted to turn to the side that is going to fall backwards, so that it does not inadvertently turn forward. Here, the storage body 2 and the outer box 1 may be held by the storage state holding means in a state where the storage body 2 is completely stored in the outer box 1. As the storage state holding means, for example, the rear end of the storage body 2 or the outer box 1
A magnet is attached to one of the back plate portions and a magnetic metal such as an iron piece is attached to the other, and the housing 2 is housed in the outer box 1 while the housing 2 is housed in the outer box 1. By holding the storage state in the storage case, when the storage body 2 is pushed into the outer box 1 and stored, the storage body 2 can be prevented from rattling forward by bouncing forward. Also, it is possible to prevent the storage body 2 from jumping out even in the event of an earthquake or the like. Of course, a latch or any other holding mechanism can be employed as the storage state holding means. When the housing 2 is pulled down from the outer box 1 forward and downward, the front link 4 hits the stopper 54 and is held so that the front link 4 does not descend further. (That is, a state where the storage body 2 is pulled down to the lowest position). In this state, the lower edge of the rear link 5 is located above the upper edge of the front link 4 with a gap therebetween, as shown by the imaginary line in FIG.
The lower end edge of the rear link 5 is located above the upper end edge of the rear link 5, and the gap width M therebetween is set to be about 20 mm. By setting the gap width M between the upper end edge of the front link 4 and the lower end edge of the rear link 5 to about 20 mm in this manner, the upper end edge of the front link 4 and the rear link 5 in the maximum retracted state of the housing 2. The finger is not packed between the lower edge and the lower edge (that is, the thickness of the finger is smaller than 20 mm, and the finger is not pinched if a gap of about 20 mm is provided). here,
As described above, the front link 4 is bent in the shape of a letter, and the storage body 2 is pulled down from the inside of the outer box 1 to the front lower part of the outer box 1. Is set so that the inner corner of the front link 4 faces the rear link 5 side, so that the gap between the front link 4 and the rear link 5 when pulled down most is smaller than that without the bent portion 4b. In the case of securing a gap width of about 20 mm, which does not allow the fingers to be packed, the front link 4 and the rear link 5 can be pulled down to a lower position, and thereby, from the lower end of the outer box 1 to the lower end of the storage body 2 By taking the length H long, the storage body 2 can be pulled down to a lower position, so that storage items can be easily taken in and out of the storage body 2. Further, a stopper 54 for preventing the further rotation by the front link 4 hitting at the position where the storage body 2 is rotated forward and downward from the outer box 1 and pulled down to the lowest position is provided on the shaft support block. Since the vicinity of the end of the front link 4 on the side of the outer box 1 is abutted against the stopper 54, the position of the stopper 54 becomes a high position that is difficult to reach. , And there is no danger of stuffing fingers. In the present invention, as described above, the ends of the front link 4 and the rear link 5 on the side of the shaft support portion to the shaft support block 20 are bent in an elliptical shape. In the state where the storage body 2 is housed in the outer box 1, the front link 4 and the rear link 5 are each formed with the bent portions 4 a, 5 a of the angled corners. Inner corner is outer box 1
Are arranged so as to face the opening side of the outer box 1. When the storage body 2 is turned down toward the front lower side of the outer box 1 from the state of being stored in the outer box 1, the front link 4 and the rear link 5 3, the inner corners of the angled corners of the U-shaped bent portions 4a and 5a are turned so as to face the front end of the bottom plate 11 of the outer box 1, and as a result, as shown in FIG. The line connecting the pivots a and b of the front link 4 which is shaped like a letter while being housed in is inclined obliquely so that the a is located forward and below, and the line connecting the pivots c and d is C can be pivoted to a position inclined obliquely so as to be located forward and below, so that when the storage body 2 is pulled down to the front lower side of the outer box 1, the link is moved to the bottom plate 11 of the outer box 1. The lowermost position, where the link does not hit the tip of the link, can be lowered to a lower position compared to the conventional example where the link is linear. It is those that can. The lower portions of the front links 4 on both the left and right sides are integrally connected by a connecting member 9 made of a bar material. Here, as described above, when the lower portions of the front links 4 on the left and right sides are integrally connected by the connecting member 9 made of a bar material, the housing 2 that rotates via the link mechanism 3 and the rotation of the front link 4 The bar-shaped connecting member 9 which rotates with the movement is set so as not to collide with each other during the mutual rotation. According to the first aspect of the present invention, as described above, the shaft support block is provided with the wood screw insertion hole and the bolt screw hole, and the side plate is opened on the inner surface side. A retaining hole is provided, and the wood screw inserted from the wood screw insertion hole provided in the shaft support block body is fixed to the side plate inside the outer box, and a bolt is screwed into the bolt screw hole to prevent the tip of the bolt from coming off. Since the bolt is inserted into the hole, even if the wood screw is loosened, the presence of the bolt inserted into the retaining hole prevents the shaft support block from falling off the side plate of the outer box with a simple configuration.
