Abstract: PURPOSE:To rotate a spur gear so as not to run on a sliding flat surface and disengage from a rack even though mounting variations of the rack and of a slide groove are produced by making coplanar a rack tooth edge and the sliding flat surface. CONSTITUTION:As a driving device is actuated manually or by an electric motor, a gear shaft 4 and spur gears 5 are rotated to force the spur gear 5 to be engaged with a rack 14c and moved vertically. Hereby, a shelf and a frame 2 are vertically moved, kept horizontally by the spur gears 5 simultaneously vertically rotated on the left and right racks 14c. Thus, a slide member 3 moved vertically in the same sliding groove 14a can smoothly be slid without any slanting and allows operation force applied on a dial to be reduced. Further, since a rack teeth edge and a sliding flat surface are flush with each other, the spur gears 5 can be rotated without running on the sliding flat surface or without being disengaged from the racks 14c even though there are produced mounting variations of the racks 14c and the sliding groove 14a, and the slide member slides on the sliding flat surface during its sliding action.

Abstract: PURPOSE:To provide the constitution, wherein even if a solenoid is designed in a high-output design, there is no breakage due to a shock at the time of suction of a plunger and the solenoid is superior in durability, of the solenoid which drives a goods carrying-out mechanism, such as an automatic vending machine. CONSTITUTION:A solenoid 10 is formed into a structure wherein a coil bobbin wound with a coil is molded by insulating coating and the molded coil bobbin is arranged in a frame body. The frame body 22 is constituted of a U-shaped member 16 and a flat plate-shaped member 15. A plunger 19 is inserted in an insertion hole formed in the coil bobbin and is abutted on a projected surface 16h of the member 16.

Abstract: PURPOSE:To prevent the rightward or leftward inclination of a shelf, to move the shelf by a relatively small force and to eliminate disturbance of entrance of food in a lower part by forming of upper and lower rollers fixed to left and right innermost parts of a frame, and so disposing the upper roller as to be brought into contact with this side of a slide groove and the lower roller as to be brought into contact with the innermost side face of the groove under the upper roller. CONSTITUTION:An upper roller 3a, a lower roller 3b and a spur gear 5 are disposed in the innermost part of a frame 2. Accordingly, the larger a load to be applied to a shelf 1 is increased, better the roller 3a is brought into contact with this face of a slide groove 14a, and the stronger the roller 3b is brought into contact with the innermost side face of the groove 14a. Since the gear 5 is strongly engaged with a rack 14b so that their rotary frictional force is increased, the frame 2 for holding the shelf 1 is tightly held at its position to eliminate dropping, lateral inclination of the shelf 1. A large force is not required to move the shelf 1 while placing food on the shelf 1, and the shelf 1 is not inclined.

Abstract: PURPOSE:To free a rack from excessive tilting and make it movable with ease by a mechanism in which an upper roller and lower roller attached to a frame for holding a rack at inmost positions at the right and the left are fitted in and held by vertical sliding grooves and gears and stoppers are provided to the frame and racks for the gears inside the refrigerator. CONSTITUTION:An upper roller 3a and a lower roller 3b are attached at an inmost position to a frame 2 for holding a rack and rolled and held in a vertical sliding groove 13a inside a refrigerator. The two rollers are put out of alignment, the upper roller 3a drawn slightly to the front and the lower roller 3b pushed slightly to the back. To the frame 2 are provided a gear 5 meshing with a rack 14 set vertically inside the refrigerator and a stopper 7 engaging with a ratchet 6. By pulling a wire 12 the stopper is put out of engagement so that the upper and lower rollers roll to vertically move with ease. After the movement, the rollers are held securely with the upper roller on the front side of the sliding groove and the lower roller on the back side; this confinement within the breadth of the sliding groove does not allow the rack to tilt excessively.

Abstract: PURPOSE:To enable an entire opening plane of a thermal insulated box to be utilized for loading or unloading items and to improve a convenience in use by a method wherein a partition member is fixed to an opening edge at a non-pivoted rear surface of a right-left opening type door, partition members for both doors are abutted to each other to make a sealed state within a refrigerator. CONSTITUTION:When a door 7A is closed, side surfaces of both partition members 18 are abutted to each other at a central part while guide projections 22 of the partition plates 18 are positioned near rear parts of guiding surfaces 16 of opposed guides 15 at an upper and a lower edges of an opening 5A of a thermal insulated box 5, and then an interior 8 of refrigerator is kept air tight. When the door 7A is opened, the partition plates 18 are pulled toward the pivoted portion of the door 7A by a spring 27, resulting in that as the door is released, the guide projections 22 are slid on the guide surfaces 16, rotated in a clockwise direction around a holding member 19A and released. When the door 7A is closed, it may operate in opposite to that of the door opening operation. In turn, as the door 7A is closed, the guide projections 22 are guided into the guide surfaces 16 of (-)-shaped recesses of the guide 15. The door is slid on the guiding surfaces 16, whereby when the door 7A is closed, side surfaces of the both partition plates 18 are abutted to each other at a central part near the rear portions.
