Description

  The present invention relates to a weight scale that can be folded compactly and easily stored.

  Scales are often left on the floor when not in use, which can easily interfere with cleaning. Therefore, as a weight scale that does not get in the way when not in use, it has a base on which both feet can ride and a base storage frame that is fixed to the lower part of the side wall of a dressing room or washroom, and the front end of the base and the lower end of the base storage frame can be rotated Has been proposed (Patent Document 1). The weight scale is used by rotating the base from the base storage frame to the floor and putting it on the floor, with both feet on the base. When not in use, the base can be raised and stored in the base storage frame.

  However, since this weight scale fixes the base storage frame to the wall, if there is an object in front of the fixed base storage frame, the base cannot be brought down and the weight cannot be measured. For this reason, it was necessary to leave an empty space in front of the base storage frame, and objects could not be placed. Further, the place where the weight is measured is fixed in front of the wall to which the base storage frame is fixed, and the weight cannot be measured at a free place.

  The problem to be solved by the present invention is to provide a scale that is excellent in storability and that can measure the weight in a free place.

  In order to solve the above-mentioned problem, there is provided a load detecting means having a pair of footrests for separately placing a right foot and a left foot, detecting a load applied to the footrest and outputting a signal corresponding to the load. Provided on each of the footrests, the footrests are pivotably connected to each other so that the footrests can be overlapped with each other, and the weight is calculated based on the signal from each of the load detecting means. Provided is a folding scale that includes a calculation unit and a display unit that displays the weight calculated by the calculation unit.

This folding scale is more preferable when the following configuration is added.
1) The footrests are arranged symmetrically on the left and right, and the footrests are connected to each other by a hinge axis parallel to the symmetry axis.
2) A through-opening that overlaps with the footrests overlapped is formed in each of the footrests, and the overlapping through-openings can be suspended from a protrusion such as a door knob.
3) A detachable footrest cover is provided on the upper surface of the footrest excluding the through opening.

  When not in use, it can be reduced in size by overlapping the footrests, so that it can be easily stored and does not get in the way. Moreover, since it can be folded and carried, a body weight can be measured in a free place. Other actions and effects are described in detail in the next section.

  FIG. 1 shows an embodiment of a folding scale according to the present invention. This scale includes a right foot platform 1 on which a right foot is placed and a left foot platform 2 on which a left foot is placed. The right footrest 1 is connected to the left footrest 2 via a right arm 3 integral with the right footrest 1, a display 4, and a left arm 5 integral with the left footrest 2 in order.

  The right footrest 1 and the left footrest 2 are arranged symmetrically as shown in FIG. The right arm 3 is fixed to the display 4 at the left end, while the left arm 5 is branched at the right end to sandwich the display 4 from the side. Hinge shafts 7a and 7b are attached to the branch portions 6a and 6b sandwiching the display device 4 in parallel with the symmetry axis of the footrest, and the hinge shafts 7a and 7b are rotatably supported by the display device 4. Has been. The display 4 is formed in a dome shape as shown in FIG. 2 (b) so as not to interfere with the rotating left arm 5. Therefore, as shown in FIG. 3, the left footrest 2 can be rotated around the hinge shafts 7 a and 7 b and overlapped with the right footrest 1.

  The right footrest 1 and the left footrest 2 are respectively formed with through openings 8 and 9 penetrating vertically as shown in FIG. The through openings 8 and 9 overlap as shown in FIG. 4 when the left footrest 2 is overlapped with the right footrest 1. Therefore, the folded weight scale can be hung by hooking the through openings 8 and 9 on a projection such as a door knob. If the weight scale is suspended, the weight scale can easily enter the field of view, and it becomes easy to measure the weight regularly. Moreover, the suspended scale does not take up space and does not get in the way.

  A pressure sensor 11 is incorporated in the right footrest 1 as shown in FIG. The pressure sensor 11 outputs a signal corresponding to the detected load, and the output signal is input to the arithmetic device 10 incorporated in the display 4. A similar pressure sensor 12 is incorporated in the left footrest 2, and an output signal from the pressure sensor 12 is also input to the arithmetic device 10.

  The arithmetic device 10 calculates the weight based on the signals from the pressure sensors 11 and 12, and outputs a signal corresponding to the calculated weight. This output signal is input to the display device 13 incorporated on the upper surface of the display device 4, and the display device 13 digitally displays the weight based on the input signal.

  As shown in FIG. 6, for example, the wiring between the pressure sensor 12 and the arithmetic unit 10 is provided with a hinge shaft 7a protruding inside the display 4, and a wiring hole 14 is formed at the shaft end of the hinge shaft 7a. Then, the wiring hole 14 can be communicated with the wiring path 15 formed in the branch portion 6a of the left arm, and the signal line 16 can be passed through the wiring hole 14 and the wiring path 15.

  As shown in FIG. 7, a footrest cover 17 is attached to the upper surface of the right footrest 1 and the left footrest 2. The footrest cover 17 has holes 18 corresponding to the through openings 8 and 9 of each footrest so that the weight scale can be suspended from a doorknob or the like with the footrest cover 17 attached. It has become. The footrest cover 17 is preferably a detachable cover. In this way, the weight scale can be kept clean by washing or replacing the footrest cover 17. Further, when several types of footrest covers 17 having different colors, materials, shapes of surfaces that contact the soles, and the like are selectively used, the scale design can be adapted to the user's preference.

  Since this weight scale can be miniaturized by superimposing the right footrest 1 and the left footrest 2 on each other when not in use, it can be easily stored and does not get in the way. Moreover, since the folded weight scale can be carried, the weight can be measured in a free place.

  As shown in FIG. 8, the right foot rest 1 and the left foot rest 2 are connected to each other via the right arm 3, the display 4 and the left arm 5, which are connected to each other as shown in FIG. The right foot rest 1 and the left foot rest 2 may be overlapped on the upper side of the display 4 as shown in FIG. Further, as shown in FIG. 10, the right foot rest 1 and the left foot rest 2 may be pivotally connected to each other, and the left foot rest 2 may be rotated in parallel with the floor to overlap the right foot rest 1. In short, it is only necessary that the right footrest 1 and the left footrest 2 can be rotated and overlapped with each other.
