As a result, the stopper projection 51 rises in the storage shelf 3 while being in sliding contact with the surface of the stopper guide rail 9 in FIG. In this way, the stopper convex portion 51 is always urged in the direction of projecting out of the housing 50, so that when it reaches the concave portion 6, it can be in the “locked state”. Even if it is desired to stop the storage shelf 3 again at the lowered position before reaching the upper concave portion 6 after raising the 3 once, the raising / lowering stop operation can be performed without any trouble.

When the stopper convex portion 51 is locked to the upper concave portion 6 from the “lock standby state” shown in FIG. 6B, the “lock state” as shown in FIG. Stop at the storage position shown in b). When the operation of the handle 4 by the user is released and the hand is released from the lever 70, the operation relay member 53 is slid upward by an urging force acting above a compression spring provided on the lever 70. Then, the urging means of the release portion 54 acts, the release portion 54 rotates about the release shaft 54 a as the rotation shaft, the locking portion 54 b is locked to the locking opening 53 a, and the operation relay member 53 and the slider portion 52 are engaged. Are connected. Therefore, the “locked state” in the same state as in FIG. 5A can also be realized in the concave portion 6 formed above.
Here, the case where the storage shelf 3 is raised from the lowered position (see FIG. 1) to the stored position (see FIG. 2B) has been described. However, when the storage shelf 3 is lowered from the storage position to the lowered position, it is needless to say that the lock state can be released by the release by the lock release means 7.

  According to the above configuration, the storage shelf 3 can be stopped at the storage position and the lowered position regardless of the load weight of the storage shelf 3 or the fluctuation of the load weight. When the storage shelf 3 in the stopped state is moved up and down, the locked state is released by grasping the unlocking means 7 provided on the handle 4, so that the unlocking operation can be performed with one hand, and the storage shelf 3 is moved upward or downward. Slide up and down to move up and down. Therefore, the raising / lowering operation of a storage shelf and the stop operation in a predetermined position can be performed smoothly, and the raising / lowering storage apparatus 1 with good usability can be realized. Moreover, since the stopper member 5 is provided on the outer surface 31b of the both side plates 31 and 31 of the storage shelf 3, the storage shelf 3 can be safely stopped at a predetermined position, and the lifting and lowering storage device 1 is also safe. be able to.

As described above, the shape and configuration of the lifting and lowering storage device 1 according to this embodiment are not limited to the illustrated examples. Further, the configuration of the lock mechanism of the storage shelf 3 and the unlocking means 7 is not limited to the illustrated example, and the formation position of the recess 6 and the installation position of the protruding pin 8 are not limited to the illustrated example. Further, the lifting and lowering storage device 1 may be provided on an upper wall surface of a kitchen floor cabinet or the like, and may be used as a storage, or may be applied to a tableware dryer. And it goes without saying that it is not limited to the elevating and lowering storage device 1 installed in the kitchen and may be installed in a living room or the like.
In some of the drawings, some of the detailed reference numerals attached to other drawings are omitted.
