Abstract: A heater on which a food plate can be supported includes a frame having three arms with holding hooks thereon which grip the food plate and includes, in the center of the frame, a heating candle. A spacing support is provided on the frame and supports a ring provided on an adjacent heater frame during vertical stacking of the heaters. An apertured plate is pivotally supported on the frame. The apertured plate can be swung out of the inner region of the frame, whereby stacking of the heaters is facilitated. The frame also supports a wind-guard member disposed around the candle. A protective member is preferably provided around the apertured plate. A supplemental device can be mounted on the frame to grip plates larger than can be gripped by the holding hooks.

Abstract: An adjustable multi-purpose stationary exercise bicycle is disclosed. The bicycle has a frame provided with a pedal mechanism and with a first seat located at a level higher than the pedal mechanism. An additional component is provided, having a second seat and a member which is movable between a portion in which it forms a backrest for the second seat and another portion in which it forms an extension of the surface area of the second seat so that a user can lie thereon. The additional component is connectable with the frame in a plurality of positions. The novel device makes it possible for the arms or legs of a user to be located in horizontal or vertical orientation ahead of, behind or above the pedal mechanism while the arms or legs are used to operate the mechanism and thus to provide exercise for the user who may be seated or in a lying position.
