Abstract: PURPOSE:To prevent a shelf from being inclined and move the shelf with a small force by a method wherein a rising part, a sliding member at a deep place of a frame for holding the shelf having a lower rib and a shaft are provided, these members are provided with a stopper mechanism for stopping a rotation of a shaft and a rack engaged with gears fixed at both ends of the shaft is provided. CONSTITUTION:A shelf 1 is comprised of a mounting part 1a, a rising part lb around the mounting part and a rib 1c. When the shelf 1 is moved up and down, at first, an operator's side of a lever 10 is lifted up and rotated, resulting in that a claw 7a of a stopper 7 is not engaged with a projection 6a of a ratchet 6 and then gears 5 fixed at both ends of a shaft 4 can be rotated while being engaged with a rack 19. Then, a frame 2 is directly moved up and down to a target position along a rail 18. As the lever 10 is released, the claw 7a of the stopper 7 is engaged with the projection 6a of the ratchet 6 under an action of a stopper spring 9, resulting in that the ratchet 6 and the gears 5 fixed to the shaft 4 may not be rotated and they are fixed there.

Abstract: PURPOSE:To prevent an abnormal sound from being generated by a method wherein a driving gear, a turning gear, a gear shaft and spur gears are rotated under a rotation of a dial, a rack is moved up and down and can be rotated and moved up and down concurrently on right and left racks and material quality of the driving gear and the turning gear is made of resin containing oil therein for either one or both of gears. CONSTITUTION:When a dial 6 is rotated, a dial shaft 7 and a driving gear 8 are rotated. Thus, a turning gear 9 is rotated and spur gears 5 at both sides are rotated together with a gear shaft 4. Right and left spur gears 5 are fixed to the gear shaft 4 and rotated in the same manner to each other, so that they may be moved up and down in the same manner at the right and left sides of the shelf 1 and no positional displacement in right and left heights occurs. Since the turning gear 9 combined with the driving gear 8 made of polyacetar is molded by resin containing plyacetal, an abnormal noise during transmittance of a driving power is prevented from being generated and in addition since lubricant oil is independently dispersed, resulting in that lubricant oil is not consumed a smooth sliding caused by the effect of lubrication can be attained.

Abstract: PURPOSE:To attain a position setting of a dial shaft by a method wherein a driving gear, a turning gear, a gear shaft and spur gears are rotated under a rotation of a dial, a rack upper shelf is moved up and down, it may be moved up and down while being held horizontal, and in addition, a stopper arranged in a dial shaft and a rib for position setting arranged at a frame are provided. CONSTITUTION:When a dial 6 is rotated, a dial shaft 7 and a driving gear 8 are rotated. Then, a turning gear 9 engaging with the driving gear 8 is rotat ed, and spur gears 5 at both sides are rotated together with a gear shaft 4. Right and left spur gears 5 are fixed to a gear shaft 4 and are rotated in the same manner to each other, so that a shelf 1 is moved up and down in the same manner at right and left sides and no positional displacements in right and left heights occurs. In the event that the dial shaft 7 is apt to move in a direction A, a stopper part 7a is abutted against a position setting rib 7c. A stopper shaft 7b is not moved due to its fixing at a fixing rib 2f for a frame 2b and thus the dial shaft 7 is restricted by the position setting rib 7c against a movement in a direction A.

Abstract: PURPOSE:To prevent an inclination of right and left side of the shelf member and enable the shelf to be moved with a low force by a method wherein a driving ear, a rotating gear, a sliding groove for slidably holding a sliding member and holding it and a rack engaged with a spur gear formed in a right and left deep direction in a refrigerator adjacent to the sliding groove are arranged. CONSTITUTION:A frame 2 is formed such that a spur gear 5, a driving gear 8 and a rotating gear 9 are covered from above and below from within the refrigerator. When a shelf 1 is moved up or down, at first a dial 6 is rotated to cause a dial shaft 7 and the driving gear 8 to be rotated. Thus, the rotating gear 9 engaged with the driving gear 8 is rotated and then a gear shaft 4 and both side spur gear 5 are rotated. At this time, the spur gears 5 are moved while being engaged with the rack 14b through the gear shaft 4. Since the right and left spur gears 5 are fixed to the gear shaft 4 and rotated in the same direction, it is moved up and down at the right and left sides of the frame 2, i.e., the shelf 1 and no displacement of the right and left heights is produced. Under a state in which the shelf 1 is stopped, the driving gear 8 and the rotating gear 9 may form a stopping mechanism and even if foods are placed on the shelf 1, the shelf, may not be lowered.
