Abstract: A stoppage-maintaining device for maintaining a baby carriage either in a folded or an unfolded state. The handle bar is pivotally connected to a rear leg by a pivoting stoppage-maintaining bar. The stoppage-maintaining bar has two concave grooves on two surfaces which are alternately engageable, as the bar rotates, with a protrusion on an upper end of a stopper sliding on the rear leg. Also, extending upwardly from the stopper is an engagement plate which, when overlapped with an elastic plate on the rear leg, prevents the rotation of the stoppage-maintaining bar from its unfolded state. The engagement plate is biased toward the elastic plate.

Abstract: A bicycle ergometer includes an eddy current brake having a rotor assembly including an iron material having a carbon content of 0.12% or less and a silcon content of 0.35% or less, a stator provided in the rotor assembly, a plurality of exciting coils provided on the stator, and a power source for energizing the exciting coils. The ergometer includes an input panel for inputting physical attributes of the user, e.g., age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user's heart rate in a predetermined range. The method of using the ergometer enables a user to select a physical strength program and a weight reduction program with the selected program reflecting the age, sex, and the present physical condition of the user.

Abstract: A reclining mechanism for controlling the inclination angle of a back rest in a baby carriage includes a horizontal cross bar connected to two vertical frame bars to form a U-shape. On the back of the backrest, a rack having several horizontal grooves can selectively engage the cross bar. A vertically movable releasing plate has inclined surfaces so that the cross bar can be raised out of the grooves against the biasing force of a pressure plate. The cross bar is connected to a head protection plate which rotates and closes off the top of the back rest when the back rest is reclined by sliding the cross bar down the rack.

Abstract: A bicycle ergometer includes an eddy current brake having a flywheel rotor assembly including an inner part of iron material having a carbon content of 0.12% or less and a silicon content of 0.35% or less, a stator provided inside the rotor assembly, a plurality of exciting coils provided on the stator, and a power source for energizing the exciting coils. The outer part of the flywheel rotor can be made of concrete. The ergometer includes an input panel for inputting physical attributes of the user, e.g., age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user's heart rate in a predetermined range.

Abstract: A rehabilitation training device and method in which a target heart rate is input, the heart rate is measured and a load in an ergometer operated by the person undergoing rehabilitation is changed accordingly. There are four steps in the training: (1) warm up--the load is increased to have the heart rate linearly approach the target value; (2) automatic--the load is varied to maintain the heart rate at the target; (3) interval--the load is alternated between its average value in the automatic step and a fraction thereof, and (4) cool-down-the load is gradually decreased.

Abstract: A wheel caster for a baby carriage in which a caster body is rotatable about a holder attached to a leg of the carriage. A stopper pivots in the caster body and is engagable with a vertical groove in the holder to prevent further rotation. The stopper has bosses which fit into vertical grooves in opposed arms of the caster body. Interiorly facing partial collars are formed in the arms beneath the grooves. Tabs on the stopper are engaged beneath the collars so that the stopper can not be removed but can nonetheless be easily assembled.

Abstract: A reversible cover for a baby seat with a three-dimensional seat support, comprising a core of foamed urethane with a smooth side and a side with hills and valleys and a cover around the core. The cover is made of air breathing seersucker on the smooth side of the core and is made of soft, insulating pile on the hill-and-valley side. The cover closely conforms to the seat support and can be reversed with the pile side being used during the winter and the seersucker side during the summer.

Abstract: A combination baby carriage and shopping cart in which the main baby carriage part comprises foldable front and rear leg bars and a handle bar. A soft basket is supported by a U-shaped frame pivoting at its front on the baby carriage. The rear of the basket has a folding panel or belt which, when folded, is attachable at its middle to an upper portion of the baby carriage backrest so as to collapse the basket.

Abstract: A collapsible body support structure is provided having a pair of parallel support legs, a transverse bar and a substantially U-shaped carrier frame. The transverse bar contains at least two bar sections pivotally connected together. The transverse also includes end portions, which are secured to the support legs. The substantially U-shaped carrier frame includes a bight arm formed of at least two carrier sections which are pivotally connected together and have a pair of parallel arms. The parallel support legs have end portions. Pivot supports are pivotally mounted on the upper end portions of the support legs for pivotal movement of the carrier frame between the stored position adjacent to the support legs and an extended position. Spring-biased stopper plates are pivotally connected to the support legs for retaining the carrier frame in the extended position.
