[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. The outer box 1 is like a top bag, and is attached to a high place in a room such as an upper part of a wall or a lower part of a ceiling. The outer box 1 has an opening at the front, and a door may be attached to the opening at the front so that the door can be opened and closed as necessary. A storage body 2 is disposed in the outer box 1, and the storage body 2 is rotated via a link mechanism 3 to thereby store the storage body 2.
Can be pulled down from inside the outer box 1 to the lower front of the outer box 1.

As shown in FIGS. 1 to 7, the link mechanism 3 has one end rotatably pivotally supported on the side surface of the outer box 1 and the other end rotatably supported on the side surface of the housing 2. It is constituted by a parallel link consisting of a pivotally linked front link 4 and a rear link 5. Here, the front link 4 and the rear link 5 are both formed in a letter shape, and in a state where the storage body 2 is stored in the outer box 1, as shown in FIG. 4,
The rear link 5 is arranged so that the inner corner of each angled corner of the rear link 5 faces the opening side of the outer box 1. The front link 5 and the rear link 6 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.

As shown in FIG. 8, the housing 2 is provided with a net 14 or a plate having a bottom and a back between the left and right side plates 13 facing each other, and is fixed. . As shown in FIGS. 8 and 11, a shaft support plate 15 is fixed to an upper portion of the outer surface of the side plate 13 of the housing 2 with a fixing tool such as a screw. The shaft support plate 15 is made of a metal plate, and is attached to the front half of the upper portion of the side plate 13 at an angle such that the rear portion is upward and the front portion is downward. The upper shaft portion 16 projects outward from the upper portion of the shaft support plate 15 that is obliquely inclined, and the projecting portion 17 that projects outward from the lower portion.
And a lower shaft portion 18 protrudes outward from the protrusion portion 17.

Then, as shown in FIG.
A hole formed at the upper end of the rear link 5 is rotatably fitted to the lower shaft portion 18, and a hole formed at the upper end of the rear link 5 is rotatably fitted to the upper shaft portion 16 and mounted.
At the lower part of the side plate 19 of the outer box 1, a pivot block 20 having a shape as shown in FIG. 12 is attached by screws as shown in FIG. 10, and the front link 4 is attached to the pivot block 20. And the lower end of the rear link 5 are pivotally supported.

The pivot block 20 is integrally formed by die-casting aluminum. As shown in FIGS. 10 and 12, the support block body 20 has a damper storage section 2 for storing and mounting a damper 21 formed of a spiral spring.
And a damper housing 25 for housing and mounting a damper 24 made of an oil damper.
The main block is formed by integrally connecting an upper block section 26 provided with a connecting block section 27 which is inclined obliquely. Then, as will be described later, the dampers 21 and 24 are stored in the damper storage portions 22 and 25, respectively, and the lower ends of the front link 4 and the rear link 5 are attached by shafts, and the side plate 1 is screwed.
9, the support block 20 functions as a mounting member for mounting a damper, a cover as a cover material, and further, each lower end of the front link 4 and the rear link 5. This serves as a member for supporting the portion.

A self-supporting leg 28 hangs downward from the inclined connecting block 27, and the lower end of the self-supporting 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. here,
It is conceivable to project the entirety of the connecting block portion 27 downward so that the entirety of the connecting block portion 27 comes into contact with the bottom plate 11. However, this increases the material of the pivot support block body 20 and increases the cost. Inclined connection block 27
By partially suspending the self-supporting leg portion 28 from above, the material can be reduced and the cost can be reduced even though stable self-supporting can be achieved. A small positioning protrusion 56 projects forward from the lower end of the front end of the support block 20, and the support block 20 is biased toward the front end of the lower end in the outer box 1. At the time of mounting, the positioning small protrusion 56 is aligned with the front end edge of the opening of the outer box 1, whereby positioning of the support block 20 with respect to the outer box 1 in the front-rear direction is performed. Here, it is conceivable to align the entire upper and lower surfaces of the front end surface of the lower block portion 23 with the front end edge of the opening of the outer box 1 without providing the positioning small projections 56. Bottom plate 11
When it is made to stand on its own, the entire upper and lower surfaces of the front end surface of the lower block portion 23 may not be exactly flush with the front end edge of the opening of the outer box 1, making it difficult to see.
In such a case, there is no such fear.

At the upper end of the support block 20, there is provided a projection 53 for preventing the link from falling. As will be described later, the rear link 5 is used to prevent the link from falling when the housing 2 is housed in the outer box 1. The rear link 5 is prevented from rotating rearward by hitting the projection 53, and is prevented from falling backward in a state where the storage body 2 is stored in the outer box 1. As shown in FIGS. 9 and 10, a damper storage portion 22 is formed by recessing the inner surface side of a lower block portion 23 at the lower portion of the shaft support block body 20. 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.
A spring damper 21 composed of a spiral spring is housed in the damper housing 22. A damper locking portion 31 is provided in the damper storage portion 22, and locked portions 32 are provided at both ends of a spiral spring constituting the damper 21, respectively. 32 is locked to the damper locking portion 31, and the locked portion 3 at the other end of the spiral spring
2 is engaged with a split groove 33 provided at the tip of the shaft 30. By providing the damper 21 composed of the spiral spring in this manner, the damper 21 composed of the spiral spring becomes a resistance when the housing 2 is turned downward from the inside of the outer box 1 toward the front and down. is there.

As shown in FIGS. 9 and 10, a damper storage portion 25 is formed by recessing the inner surface side of the upper block portion 26 at the upper portion of the shaft support block body 20. The central portion of the damper storage portion 25 is formed. Is provided with a hole 34 penetrating inside and outside. A damper 24 made of an oil damper is housed in the damper housing part 25 and attached to the shaft support block body 20 with screws.
A rotating body 38 having a flange 37 is mounted on the rotating drive shaft 35 of the damper 24 composed of an oil damper so as to rotate integrally with the rotating drive shaft 35, and the cylindrical portion 39 of the rotating body 38 is connected to the shaft support block body. 20 is rotatably inserted through an oil-containing bush 42 into a hole 34 of the cylindrical portion 3.
A rectangular shaft portion 39a having a substantially rectangular cross-sectional shape and protruding from the distal end portion 9 protrudes outward from the hole. A hole 40 at the lower part of the rear link 5 is fitted into the rectangular shaft portion 39a, and a retaining plate 41 larger than the hole 40 is applied to the distal end surface of the rectangular shaft portion 39a.
1 is fixed to the rectangular shaft portion 39a so that the rear link 5 does not fall out of the rotating body 38. Here, the flange 37 of the rotating body 38 is located between the periphery on the inner surface side of the hole 40 and the case of the damper 24 so as not to come off. The rectangular shaft portion 39a protrudes outward from the shaft 30 as shown in FIG. 10, and as a result, the pivot at the lower end of the rear link 5 is larger than the pivot at the lower end of the front link 4. It is located offset to the outside.

A rectangular shaft portion 39a provided below the rear link 5.
As shown in FIG. 13, the hole 40 for inserting
The narrow portions 40a and 40b are formed so as to communicate with each other.

Thereafter, when the rear link 5 rotates in the arrow direction, the rear link 5
The rectangular shaft 39a rotates together with the link 5, and the oil damper

It acts as a resistance to turning in the direction.

By the way, when the housing 2 is completely housed in the outer box 1, the rear link 5 hits the link falling prevention projection 53 provided on the shaft support block 20, and the rearward rotation is prevented. This prevents the storage body 2 from falling backward when the storage body 2 is 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 , Back link 5
Is located above and behind the lower shaft supporting member d, and the line connecting the shaft supporting members a and b is backward when the storage body 2 is completely housed in the outer box 1. And is inclined obliquely so as to be located above, and the line connecting the shaft supporting portions c and d is obliquely inclined such that c is located rearward and above,
As a result, in a state where the storage body 2 is completely stored in the outer box 1, a force to rotate the storage body 2 toward the side of falling backward by its own weight is applied, and the storage body 2 is inadvertently rotated forward. Not to be. FIG. 13 (a) shows a state in which the housing 2 is completely housed in the outer box 1, and the angle of play α is substantially the same as the inclination angle of the line connecting the pivots c and d with respect to the vertical. Has become. Therefore, in a state where the storage body 2 shown in FIG.
In FIG. 13B, the housing 2 is moved from the outer box 1
While the storage body 2 is rotated by the angle α from the state where the storage body 2 is completely stored, the damper 21 formed of a spiral spring provided on the shaft support portion of the front link 4 becomes a resistance.
The line connecting the shaft supporting portions a and b and the line connecting the shaft supporting portions c and d are inclined, and the housing 2 is stored against the total force of the force that the storage body 2 tends to rotate by its own weight. By rotating the body 2 forward, the body 2 can be rotated, and the angle α can be rotated with a light force due to the lack of resistance of the damper 24 composed of an oil damper. Then, after the rotation of the angle α, when the line connecting the shaft supports A and B and the line connecting the shaft supports C and D exceed the vertical and are inclined in the opposite direction to the above, the own weight of the housing 2 causes the housing 2 to Acts as a force to rotate forward and downward,
After the rotation by the angle α, the rectangular shaft portion 39a rotates together with the rear link 5 as described above, and the damper 2 formed of an oil damper.
Numeral 4 functions as resistance of the rotation of the rear link 5 in the direction of the arrow in FIG. As a result, when a force that rotates the storage body 2 forward and downward by its own weight by rotating by the angle α starts to act, the damper 24
Both the damper and the damper 21 work as a resistance and move down slowly.

Here, the storage body 2 and the outer box 1 may be held by the storage state holding means 55 in a state where the storage body 2 is completely stored in the outer box 1. As shown in FIG. 3, the storage state holding means 55 includes a magnet 55a at one of the rear end of the storage body 2 and the back plate side of the outer box 1, and an iron piece 55b at the other. The housing 2 is pushed into the outer box 1 by attaching the magnetic metal and holding the housing 2 in the outer box 1 by the housing state holding means 55 in a state where the housing 2 is housed in the outer box 1. When it is stored, the storage body 2 can be surely prevented from rattling as it bounces forward, and the storage body 2 can be prevented from jumping out even during an earthquake or the like. Of course, a latch or any other holding mechanism can be employed as the storage state holding means 55.

As shown in FIGS. 1 and 14, the front link 4,
The rear link 5 has an L-shaped stopper piece 43,
In the state where the horizontal pieces 43a and 44a of the stopper pieces 43 and 44 are rotated downward to the front of the outer box 1 to the lowermost position and pulled down, The horizontal piece 44a of the stopper piece 44 of the link 5 hits the horizontal piece 43a of the stopper piece 43 of the front link 4, so that the rear link 5 cannot rotate any more. 4, the rear link 5 cannot rotate forward and downward any more, and the housing 2 is stopped at the lowest position. Here, the horizontal pieces 43a, 4
4a, a magnet 45 is provided, and the storage body 2 is turned to the lower front of the outer box 1, turned to the lowest position, pulled down and stopped, and the magnet 45 is turned to the other iron sideways. It is magnetically attached to the piece 43a (or the horizontal piece 44a). In this case, in the attached drawings, the housing 2 is
In the state of turning forward and downward and turning down to the lowest position, the horizontal piece 44a of the stopper piece 44 of the rear link 5 is moved by the magnet 45 to the side of the stopper piece 43 of the rear link 5 of the front link 4. By contacting the piece 43a, the housing 2 is stopped at the lowest position. In this way, the magnet 45 is magnetically attached to the other iron horizontal piece 43a (or the horizontal piece 44a) in a state where the storage body 2 is rotated to the lower front position of the outer box 1, rotated to the lowest position, and pulled down. By doing so, the storage body 2 stops at the lowermost position and bounces upward and does not rattle, and the storage body 2 holds the state stopped at the lowermost position.
Therefore, in the present embodiment, the magnet 45 is magnetically attached to the iron horizontal piece 43a (or the horizontal piece 44a), so that the storage body 2 is pulled down to the lowest position and the front link 4
And a rear link 5.

The holding means for holding the front link 4 and the rear link 5 in a state where the storage body 2 is pulled down to the lowest position is not limited to the magnetic attachment by the magnet 45 described above. Other latching or any other holding mechanism can be employed. By the way, in the present invention, as described above, the front link 4 and the rear link 5 are formed in the shape of a letter, and the front link 4 and the rear link in the shape of a letter in a state in which the storage body 2 is stored in the outer box 1. Since the inner corner side of each angled corner of the link 5 is arranged so as to face the opening side of the outer box 1, the storage body 2 is moved from the state of being stored in the outer box 1 to the front lower side of the outer box 1. When it is turned down and turned down, it turns so that the inner corners of the angled corners of the front link 4 and the rear link 5 that are shaped like a letter face the front end of the bottom plate 11 of the outer box 1. As shown in FIG. 7, the front link 4 is shaped like a letter in a state of being stored in the outer box 1.
The line connecting the pivots i and b is inclined diagonally so that i is located forward and below, and the line connecting the pivots c and d is oblique so that c is located forward and below. When the storage body 2 is pulled down to the front lower side of the outer box 1, the link is turned to the bottom plate 1 of the outer box 1.
1 can be lowered to a lower position as compared with the conventional example in which the link is linear, in a state where the link does not hit the front end. Further, as described above, the front link 4 and the rear link 5 are arranged so as to be shifted in the horizontal direction so as to rotate in different vertical planes parallel to each other. In addition, even if the front link 4 and the rear link 5 rotate to a position where they overlap each other, there is no problem. In this regard, the rotation range between the front link 4 and the rear link 5 is increased, and the housing 2 is moved to the outer case. 1 can be pulled down to a lower level position in front of and below. As a result, when the housing 2 is pulled down to the lower front of the outer box 1 as shown in FIG. 1, the upper end of the housing 2 is positioned forward and lower than the lower front end of the outer box 1. It is also possible to

Here, the shaft supporting portion b of one end of the front link 4 to the outer box 1 is located at the lower part of the front end of the outer box 1 as shown in the attached drawing, so that the front end of the front link 4 has a simple configuration. Link 4
Can be rotated more greatly so as to be in an obliquely lower position beyond the front end of the bottom plate 11 of the outer box 1, and at this point, the storage body 2 can be further moved to a lower level position at the lower front of the outer box 1. It can be pulled down.

By the way, when the line connecting the shaft supports A and B of the front link 4 and the line connecting the shaft supports C and D of the rear link 5 are horizontal, the moment acting on the housing 2 is maximum. Assuming that the position where the moment is maximum is the lowest position of the storage body 2, the operation force for rotating and raising in the opposite direction to store the storage body 2 in the outer box 1 requires the maximum initial operation force. However, as described above, the storage body 2 is
The line connecting the pivots at both ends of the link is tilted obliquely downward so that the pivot on the storage body 2 is at the bottom, and is pulled down to the lowest position. Means that a moment smaller than the maximum moment is acting. As a result, in the state of being pulled down to the lowest position, it can be pushed up with a light force at the beginning of pushing up when storing it again again (in this case, The return spring force by the damper 21 composed of a spiral spring also acts, so that it can be pushed up with a lighter force). Then, in a state where the housing 2 is started to be pushed up and momentum is applied, the line connecting the shaft support portions at both ends of the link is in a horizontal state. The housing 2 is pushed into the outer box 1 beyond the position where the maximum moment acts on the housing 2. Since it can be rotated, it can be smoothly returned with a light force.

The front links 4 located on both left and right sides or the rear links 5 located on both right and left sides are connected by a connecting member 9, so that both front links 4 or both rear links 5 are integrated. It can rotate in conjunction with it. In the embodiment shown in FIGS. 1 to 7, the lower portions of the left and right front links 4 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 both the left and right sides are integrally connected by the connecting member 9 made of a bar material, the link mechanism 3 is used.
The storage body 2 that rotates through the link and the bar-shaped connecting member 9 that rotates with the rotation of the front link 4 are set to have a positional relationship such that they do not collide with each other during the mutual rotation. .

As shown in FIG. 8, the lowermost portions of the front ends of the both side plates of the storage body 2 have downwardly projecting portions 61 downward.
And both ends of the handle bar 60 are rotatably attached to the downward projection 61, and the handle bar 60 is gripped by hand to perform the lifting operation by the above-described rotation of the housing 2. It is. The handle bar 60 is used to move the housing 2 to the outer box 1.
It is located slightly forward of the pivot portion B at the lower end of the front link 4 in a state of being housed therein. Therefore,
The connecting member 9 made of a bar material for connecting the lower portions of the front link 4 is disposed at a position avoiding the handle bar 60, and furthermore, as described above, the storage member that rotates via the link mechanism 3 The body 2 and the bar-shaped connecting member 9 which rotates with the rotation of the front link 4 are set so as to have a positional relationship in which they do not collide with each other during the mutual rotation.
