Next, the handling method of the storage drainage shelf 1 having the above-described configuration and the operation of each part will be described with reference to the drawings.
FIG. 5: has shown the schematic perspective view seen from the downward direction for demonstrating the accommodation state of the storage-type drainage shelf concerning this invention.
In the figure, the storage-type draining shelf 1 is stored in the horizontal direction with the draining shelf 3 folded into the arm 2.

Moreover, FIG. 6 has shown the schematic sectional drawing seen from the side for demonstrating the accommodation state of the storage-type drainer shelf concerning this invention.
In the figure, the storage drainer 1 has a base 4 fixed to a front plate 122 of a fluorescent lamp box 12 to which a fluorescent lamp 121 is attached by a wood screw 123.
The arm 2 receives an urging force from the operating link 21 and the arm operating spring 23, and rotates in the closing direction and maintains the storage state rotated in the horizontal direction.
At this time, the convex portion 521 of the lock key 52 biased in the direction of the arm connection rivet 42 is in contact with the sliding surface 511 of the lock cam 51.

The pin 33 of the draining shelf 3 is inserted into both the pin groove 203 of the arm 2 and the pin locking groove 521 of the lock key 52.
Here, the stopper portion 522 b of the pin groove 203 and the pin locking groove 521 constitutes the shelf locking means 6. That is, in a state where the arm 2 is rotated downward and is not locked by the locking means 5, the convex portion 521 of the lock key 52 comes into contact with the sliding surface 511 of the lock cam 51, and by this contact, the lock key 52 is locked. Is moving in a direction opposite to the biasing direction (left side in the figure). For this reason, the stopper portion 522 b of the pin locking groove 521 blocks a part of the inlet of the pin groove 203, and the gap “W” between the left end surface of the pin groove 203 and the pin locking groove 521 is larger than the diameter D of the pin 33. It becomes smaller (D> W) and the pin 33 is locked in the pin groove 203 and cannot come out.
Accordingly, when the arm 2 is stored and while the arm 2 is rotating, the state in which the draining shelf 3 is folded over the arm 2 is reliably maintained. It is possible to prevent such a problem that the shelf 3 is accidentally pushed upward and the fluorescent lamp 121 is damaged.
Although not shown, a stover is provided so that the arm 2 does not rotate and contacts the fluorescent lamp 121.

FIG. 7: has shown the schematic perspective view seen from the near side for demonstrating the retractable draining shelf rotated to the downward direction concerning this invention.
In the figure, the retractable drainage shelf 1 has the arm 2 and the drainage shelf 3 rotated downward (vertical state) by pulling the arm handle 35 obliquely downward on the front side.
In order to rotate the arm 2 and the draining shelf 3 downward, it is necessary to rotate against the urging force generated by the operating link 21 and the arm operating spring 23. The urging force is appropriately adjusted. By doing so, it can be rotated with a small force.

Moreover, FIG. 8 has shown the schematic sectional drawing seen from the side for demonstrating the rotation state of the draining shelf of the storage-type draining shelf concerning this invention.
In the drawing, the retractable drainage shelf 1 has an arm 2 held in a vertical state, and the drainage shelf 3 is rotated in the horizontal direction.
When the arm 2 and the draining shelf 3 are rotated downward (vertical state) and the convex portion 521 of the lock key 52 is removed from the sliding surface 511, the storage type draining shelf 1 is moved to the key operating spring 53. The urging force moves upward, and the convex portion 521 is locked to the locking portion 512 of the lock cam 51. Thereby, even if the arm handle 35 is released, the arm 2 is maintained in a vertical state against the urging force acting on the arm 2.

When the lock key 52 is moved upward, the stopper portion 522b of the pin locking groove 522 is moved upward, so that the locking of the pin 33 to the pin groove 203 is released and the pin locking that constitutes the cam mechanism is performed. The pin 33 is pushed out in the rear side direction by the lower surface 522b of the groove 522. When the pin 33 comes out of the pin groove 203, the draining shelf 3 receives gravity and rotates in the opening direction and is held in a horizontal state by the support stay 37. Here, the draining shelf 3 can be slowly opened by the frictional resistance by the spring washer 313.
When the arm 2 is rotated to the vertical state, the link connecting rivet 22 abuts on the lower end surface of the operating link long hole 205 to prevent the arm 2 from rotating further to the front side.

FIG. 9: has shown the schematic perspective view seen from the front side for demonstrating the use condition of the draining shelf concerning this invention.
In the drawing, the storage-type drainage shelf 1 is locked in a vertical state only by performing one operation of pulling the arm handle 35 in the storage state in the opening direction of the arm 2 (diagonally below the front side). At the same time, the draining shelf 3 is pushed out to the back side and rotated in the opening direction of the shelf to become a horizontal state, which can be set in a use state.

FIG. 10: has shown schematic sectional drawing seen from the side for demonstrating accommodation operation | movement of the draining shelf concerning this invention.
In the figure, the storage-type drainage shelf 1 is configured such that the user holds the shelf handle 36 in use and rotates the drainage shelf 3 in the shelf closing direction (upward on the front side) so that the pin 33 is pinned. The groove 203 is inserted. At this time, since the lower surface 522a of the pin locking groove 522 of the lock key 52 is pushed by the pin 33, the lock key 52 moves downward. When the lock key 52 moves downward against the urging force of the key operating spring 53, the convex portion 521 of the lock key 52 is disengaged from the engaging portion 412 of the lock cam 51, and the stopper portion 522 b is in the pin groove 203. The inlet 33 is partially blocked, and the pin 33 is locked inside the pin groove 203.

  Further, when the convex portion 521 is detached from the locking portion 412, the retractable drain shelf 1 is automatically rotated in the opening direction by the arm 2 receiving the urging force of the operating link 21 and the arm operating spring 23. try to. At this time, the user is momentarily acted upon by the urging force, and usually the hand holding the shelf handle 36 is pulled by a small distance upward on the back side. In the state where the convex portion 521 is disengaged from the engaging portion 412 of the lock cam 51, the convex portion 521 can be rotated by a minute angle in the closing direction. Then, the retractable drainage shelf 1 is brought into a state in which the convex portion 521 of the lock key 52 is in contact with the sliding surface 511 of the lock cam 51 by the rotation of the minute angle, and the urging force by the operating link 21 and the arm operating spring 23 is obtained. In response to this action, it automatically rotates in the closing direction to maintain the stored state. At this time, the arm 2 is rotated at an appropriate rotation speed by the rotary damper 44.

  It should be noted that the user can release the shelf handle 36 when the convex portion 521 is in contact with the sliding surface 511 of the lock cam 51, that is, when the user feels that the convex portion 521 is slightly pulled by the urging force. Then, even if the shelf handle 36 is released, the retractable drainer shelf 1 prevents the trouble that the pin 33 is locked by the stopper portion 522b and the drainer shelf 3 is opened. 3 can be automatically stored by the urging force.

As described above, in the storage drainage shelf 1 of the present embodiment, the user rotates the shelf handle 36 in the use state in the closing direction of the shelf, and is further pulled by the arm 2 receiving the biasing force by a small distance. Thus, the arm 2 and the drainage shelf 3 can be stored in the horizontal direction.
The operation of pulling the arm 2 that has received the biasing force by a minute distance is normally performed unconsciously. Therefore, the operation of the draining of the used state is performed by one operation of rotating the shelf handle 36 in the shelf closing direction. The shelf 3 can be stored.

Although the preferred embodiment of the foldable storage shelf of the present invention has been shown and described, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.
For example, it is not limited to a storage-type drainage shelf, but a storage shelf that is used while it is frequently used and stored, or a storage shelf that requires a large force to store heavy. Can also be applied.
