Description

[Brief explanation of the drawing]

The drawings are all related to this invention; Fig. 1 is a front view showing the general structure of a general simple scale to which this invention is applied, and Fig. 2 is a main part side showing the first embodiment. A cross-sectional view, FIG. 3 is a side cross-sectional view of the main part showing the second embodiment, and FIGS.
The figures show an example of the weighing operation of the first embodiment, and Fig. 4 shows the case when the weight on the tray is zero, Fig. 5 shows the case when only the tare is placed, and Fig. 6 shows the state shown in Fig. 5. When the zero position of the scale and plate is aligned with the pointer, Figure 7 is a front view of the scale plate showing the case where the object to be weighed is put into the air chamber in the state shown in Figure 6, and Figures 8 to 11 are An example of the weighing operation of the second embodiment is shown in FIG.
The figure shows the case when only the tare is loaded, the figure 10 shows the case when the semi-fixed pointer is moved to the zero position of the movable scale plate in the condition shown in figure 9, and the figure 11 shows the case when the object to be weighed is placed inside the tare in the condition shown in figure 10. Front view of the scale plate showing the case where the 12th
Figures to Figure 22 show the third embodiment, Figure 12 is a schematic front view of a simple scale, Figure 13 is a case where the weight indication is based on a movable pointer, and Figure 14 is a case where the weight indication is also based on a movable scale plate. 15 to 22 are front schematic views showing the weighing operation in the example of FIG.
The figure shows when the weight on the tray is zero, Fig. 16 shows when a tare is placed, Fig. 17 shows when only the pointer is returned to the zero position, and Fig. 18 shows when the rack is aligned with the pinion in Fig. 17. Figure 19 shows the state shown in Figure 18 when the object to be weighed is placed in the tray, and Figure 20 shows the state shown in Figure 19 when the weight on the tray is reduced to zero. , FIG. 21 shows 1. when the rack and pinion are disengaged following the state shown in FIG. 20. FIG. 22 is a front view of the scale plate showing the case where the rack and pinion have returned to engagement following the state shown in FIG. 21. 14...Object to be weighed, 17...Biasing mechanism, T...Mechanism for returning the display to the zero position.

Claims (2)

[Scope of utility model registration request] (1) Displaying the weight of the object to be weighed by mechanical means.
A simple scale characterized in that the scale is equipped with a mechanism for returning the display to the zero position while the scale is in a balanced state to which the weight has been added. (2) As the mechanism for returning the display to the zero position, a biasing mechanism is provided that returns the display to the zero position by a biasing force ρ that is sufficiently weak compared to the balanced force of the frame. A simple scale according to claim 1 of the utility model registration claim.
