摘要:
A defrosting heater in a refrigerator with a flammable refrigerant sealed therein, including a first glass tube (53) having a heater wire (52) inside thereof, a plug (58) covering both end opening parts of the first glass tube (53) and a second glass tube (54), a lead wire (55) piercing the plug (58) and connected to an end of the heater wire (52), and a positioning plate (57) disposed on a connection part of the lead wire (55) with the heater wire (52). Flame propagation can be prevented by setting the size of a space (58b) formed by the plug (58) and the positioning plate (59) according to the sealing quantity of the flammable refrigerant and the surface temperature of the heater wire (52), and an unstable state in a defrosting mode is prevented even when the flammable refrigerant leaks.

A defrost heater, in which the strength of an insertion force needed for inserting a second glass tube in a plug is specified to be smaller than that needed for inserting a first glass tube in a plug. Thereby, dispersion in the insertion force needed for attaching the plug with a double glass tube can be reduced, and the assembling efficiency is improved.

A safety car seat for a child has a headrest vertical moving device, a shoulder belt position control device, a sleeping support position control device, a crotch belt position control device, a footrest step position control device and a moving device for changing the size or capacity of a support space for protecting the child. The shoulder belt position control device includes two holding plates that slide along two inclined elongated holes and are connected by two pivotable control arms to a control pin that slides along a vertical guide slot in the seat backrest. Upper portions of the shoulder belts pass through slit holes in the holding plates. The upper ends of the belts can be adjusted higher, wider apart and less inclined, or lower, closer together and more inclined.

A seat body forming a backrest and a seat section is made to move along an arcuate guide with respect to a base by a relative movement guiding mechanism which is formed by combination of an arcuate guide rail and a guide member moving along the guide rail. A seat section is rotatably mounted on the seat body and a coupling member is caused to engage a linear section of the guide rail, thereby maintaining the seat section at a substantially constant inclination regardless of any movement of the seat body. Thus, it is possible to maintain the seat section in a substantially horizontal state also when the angle of the backrest is adjusted, whereby the backrest can recline without interfering with a backrest of the car seat in an automobile. Thus, an uncomfortable position is avoided when a child sits in the safety seat the backrest of which is in an inclined state.

In order to allow bending of members defining the cross-directional size of a frame of a foldaway baby carriage in association with movement of members forming side surfaces of the frame, side bars rotate with respect to front legs to draw up front leg sleeves through front leg rigid links. At this time, guide pins provided in the front legs are moved in spirally extending guide grooves which are formed in the front leg sleeves, so that the front leg sleeves rotate due to the spiral extension of the guide grooves. Thus, a front leg coupling link extending across the pair of front leg sleeves is bent about bend points. A similar structure is employed in relation to a rear leg coupling member extending across a pair of rear legs and a side bar coupling member extending across a pair of side bars.

A baby's play gym for supporting suspended toys can be reconfigured to form a magazine rack or a chair. The play gym includes upwardly convex arcuate first and second side supports arranged laterally opposite one another with a spacing distance therebetween. First and second hanger bars coupling the first and second side supports with each other for hanging toys thereon extend between upper portions of the first and second side supports. Third and fourth hanger bars for hanging other toys extend between lower portions of the first and second side supports. When reconfigured as a magazine rack or a chair, a strip member is supported from at least two of the hanger bars to form a sling trough to support books and magazines or a sling seat to support a person, while the play members are removed and some of the hanger bars may be removed.

A safety car seat for a child is provided with a headrest vertical moving device, a shoulder belt position control device, a sleeping support position control device, a crotch belt position control device, a footrest step position control device and a moving device for changing the capacity of a support space for protecting the brain, the back and respiration of a child in the seat. By employing this mechanism, it is possible to provide a juvenile safety car seat enabling implementation of comfortability and safeness as well as protection of the brain, the neck and respiration of a baby based on medical criteria for the baby.

A vehicular child safety seat includes a seat main body (1A) attached to a base body (1C) in a rotatable manner. The seat main body includes a seat portion (16), a backrest (11) reclinably hinged to the seat portion, a head guard (10) tiltably hinged to the upper edge of the backrest, side guards (12, 13) protruding perpendicularly from lateral edges of the backrest, and armrests (14, 15) protruding upwardly along side edges of the seat portion. When the backrest is in its most reclined position, and the seat main body is rotated on the base body to be transverse to the longitudinal direction of the vehicle, the seat portion and backrest are substantially coplanar and horizontal to form a baby bed. When the backrest is in a more upright position, and the seat main body is rotated to face forward or rearward in the vehicle, the safety seat is suitable for an infant, toddler or older child sitting upright. Thus, a vehicular child safety seat can be provided that can be used constantly throughout the entire childhood for a baby, an infant, and a child of school age.
