It consists of.

As shown in FIGS. 2 and 3, reference numeral 3 denotes a bearing portion, which is integrally formed with the left and right frames 2a and 2b, and is cut and raised in a pair of tongue pieces on the depth side and the front side. Provided. Reference numeral 4 denotes a roller shaft which is horizontally supported by each of the bearing portions and has one end protruding from the bearing portion on the near side. A pair of rollers 5 are provided on the depth side and the front side, respectively, and are rotatably supported between the bearing portions 3. The roller 5 has a concave groove 6 on the peripheral surface, and a spring 7 is provided between each roller 5 and the bearing 3 on the near side, and is biased so that one end of the roller shaft projects. Each roller shaft 4 is fixed at a bearing by shaft stoppers 8a and 8b.

As shown in FIG. 4, 9 is a refrigerator main body, and 10 is an inner box formed of resin. Numeral 11 denotes a foam insulation material, which is filled between the outer box and the inner box 10 of the main body 9 by foaming. Reference numerals 12 and 13 denote a pair of sliding grooves fixed to the right and left on the front side and the depth side of the inner box 10, respectively, with screws or the like (see FIG. 1).

Numeral 14 denotes a guide column, which fits into the concave groove 6 of each roller 5.

As shown in FIGS. 5 and 6, reference numeral 15 denotes a locking hole, which is provided on a side wall on the front side of the sliding groove 13 and faces one end of the roller shaft 4 protruding therefrom. An inclined surface 16 is provided at the opening 15 to facilitate insertion of the roller shaft 4.

FIG. 5 shows a state in which the shelf 1 and the frame 2 are fixed in the main body 9 of the refrigerator.
14 and is accommodated in the sliding groove 12 so that each roller shaft 4
The protruding one end on the front side of is inserted into the locking hole 15 and locked. At this time, the concave groove 6 of each roller is fixed in the front-rear direction because it is engaged with each guide post 14, and the roller shaft 4 is provided with the shaft stoppers 8a and 8b. Due to the restoring force of the spring 7 incorporated in the shaft 4 between them, a force for pushing the entire frame 2 in the direction of arrow A is fixed. In this state, as described above, the shaft 4 is inserted into the locking hole 15 and the entire shelf 1 is supported at a pair of four points on the front side and the depth side, respectively. Fixed. To move the shelf 1 up and down,

15 is disengaged, and can freely move up and down.

Further, as described above, since the roller 5 does not move in the front-rear direction due to the guide post 14, the spring 7 is compressed between the roller 5 and the bearing 3 on the near side. When the roller 5 is moved upward or downward while holding the front and left sides of the shelf in this state, the roller 5 moves upward or downward while sliding in the sliding groove 12. During the movement in the up-down direction, since the force is still applied in the direction of arrow B, there is no drop of the shelf, and each roller moves up and down along the guide pillar 14, and the shelf remains in the horizontal direction. Therefore, there is no problem even if the food is moved up and down with the food placed thereon. When the shelves 1 have been moved to the required positions, the force holding down the shelves 1 and the frame 2 is loosened, and the restoring force of the spring 7 moves in the direction of arrow A, that is, the front side, and the roller shaft 4 is locked. 15 and returns to the state shown in FIG. 5 again, and the frame 2 is fixed. If the vertical position of the shaft 4 and the locking hole 15 is shifted after moving in the forward direction, the tip of the shaft 4 moves downward by its own weight while sliding on the inclined surface 16 of the locking hole 15. Then it is hooked and fixed to the nearest locking hole.

Since each roller 5 is not displaced in the front-rear direction by the guide post 14 and is in contact with the sliding grooves 12 and 13 respectively, it is not possible for the shelf to be inclined or displaced in the left-right direction while the shelf 1 is moving up and down. Absent.

Effect of the Invention As described above, the shelf device of the present invention includes a shelf provided in a refrigerator, a frame holding the shelf, rollers, guide columns and sliding grooves engaged with the rollers, and a roller shaft. When the shelf is pressed to the depth side, the engagement between the one end of the roller shaft and the locking hole is separated, so that the rack and the frame can move in the vertical direction. When the pressure is released, it can be reengaged at a predetermined position to provide stable support. Therefore, compared to the conventional example, there is no need to remove the shelf or the frame from the inside of the refrigerator, it does not take much time, and the shelf is always kept horizontal by the engagement of the four rollers and the guide pillars.
