摘要:
A scale, especially a bathroom scale, comprises a base (10), a platform (11) and, arranged therebetween, a weighing mechanism comprising a U-shaped supporting bar (34) which is attached to the base (10) and supports indicating elements of the weighing mechanism. The mechanism also comprises two pairs of levers (12, 13) which support the platform (11). All four levers (12, 13) are at one end pivotally mounted on or in the vicinity of the corners of the base (10). The levers (12) of one pair of levers form a V-shaped lever part (15) by extending in V-shape from a plate (14) which is supported by a spring (30) included in the weighing mechanism, the spring being arranged on a longitudinally adjustable upright (31) resting against the base. The levers (13) of the other pair of levers are, at their end (21) operatively connected to the lever part, formed with a downwardly open recess (22) which rests against a corresponding, upwardly open recess (23) in the levers (12) of the lever part (15). When mounting the scale, the U-shaped supporting bar (34) is premounted with its indicating elements included in the weighing mechanism, the V-shaped lever part (15), the spring (30) included in the weighing mechanism and the associated longitudinally adjustable upright (31) are assembled to a unit, and the different parts of the base (10) are mounted in the succession: the U-shaped supporting bar (34), the lever part (15) and the two short levers (13).
摘要:
The scale is of limited height and utilizes Z-shaped flexures between the load frame and support frame. The scale can be placed in a hospital bed for weighing bedridden patients or for monitoring weight variations in bedridden patients. A cart is provided for transporting the scale from place to place and includes an inclined ramp from which the scale may be readily moved onto a bed.
