Description

[Detailed description of the invention] <Industrial application field> This invention relates to a weight scale suitable for elderly people who are unsteady on their feet, disabled people, etc. (hereinafter referred to as "elderly people, etc.").

<Prior Art> A conventional example of this type of weighing scale main body 1 is shown in FIG.

This scale body 1 includes a scale 3 and a handrail portion 17.
It consists of

The scale 3 includes a base part 5, a step part 9, and a display part 13.
It is a spring type automatic display type consisting of.

The base part 5 is installed horizontally on the floor 7.
It includes support legs 6 that are extendable and retractable.

The step section 9 is box-shaped and is mounted on the base section 5 via a spring (not shown). and,
Pressure-sensitive sensors 11 are disposed at each of the four corners between the base section 5 and the step stool section 9. Each pressure sensor 1
1 outputs a weight signal corresponding to the downward load applied to the step stool 9 when a person steps on it.

The display section 13 is attached to the front end surface of the base section 5 via a rod 15. This display section 13 has a built-in arithmetic device (not shown). and,
The weight signals output from each pressure-sensitive sensor 11 are input to this calculation device, and the average value thereof is calculated. The arithmetic device then outputs a display signal corresponding to the average value to the display unit 13. The display unit 13 digitally displays a numerical value corresponding to this display signal.

The handrail portion 17 is a pipe bent into a substantially U-shape, and the opening side of the U-shape is connected to both sides of the step stool portion 9. Such a handrail portion 17 is provided for the elderly and the like to grasp. Then, if an elderly person etc.
7, the weight of the grip will be transmitted to the step stool section 9 via the handrail section 17. Furthermore, even if an elderly person steps on one side of the step stool section 9 in order to grasp the handrail section 17 (the step section 9 will be tilted), the average value of the pressure-sensitive sensors 11 arranged at the four corners will be calculated. Therefore, the weight of elderly people etc. can be measured accurately.

<Problem to be solved by the invention> However, in the scale body 1 having the above configuration,
When an elderly person or the like leans on the handrail portion 17, there is a risk that the scale body 1 will tilt and eventually fall.

Furthermore, the weight scale 3 is required to have a predetermined height (approximately 10 cm) in order to accommodate the pressure sensor 11, etc. This height becomes an obstacle for elderly people and others to climb onto the step stool section 9.

<Means for Solving the Problems> This invention is an auxiliary device for weight scales that has been devised in view of the above problems. The scale is comprised of a base part installed on the floor, a step part that moves up and down with respect to the base part, and a display part that displays a numerical value according to the downward load applied to the step part. and a handrail portion attached to the scale, the auxiliary device being attached to the scale body, the auxiliary device comprising: an auxiliary platform having a sloped surface continuous from the step portion to the floor; A guard part that is fixed and placed above the step stool in a position that does not interfere with the human body during weight measurement, and that interferes with at least one of the handrail or the human body when the scale is tilted to prevent the scale body from tipping. and,
It is characterized by consisting of.

<Example> Hereinafter, this invention will be explained in more detail based on an example.

Note that the same members as those described in the conventional example are given the same reference numerals, and their explanations will be partially omitted.

First Embodiment (FIG. 1) The auxiliary device 40 of this embodiment is applied to the weighing scale main body 21.

The scale body 21 consists of a scale 3 and a handrail portion 25. The weight scale 3 has a base part 5 having the same configuration as the conventional example,
It includes a step stool section 9 and a display section 13. Of course, the weight scale 3 is not limited to such a spring-type automatic display type, and a balance type can also be applied.

The handrail portion 25 is composed of a base portion 27 that is approximately T-shaped in plan view and is attached to the step stool portion 9, a vertical column 29 that is attached to both sides of the base portion 27, and horizontal columns 31 and 33 that are attached to the vertical column 29 in two stages above and below. be done. Grips 32 are mounted on both ends of the upper horizontal post 31. Engagement protrusions 34 facing downward are formed at both ends of the lower horizontal column 33.

This handrail portion 25 is connected to the weight scale 3 connected in advance.
In order to attach the auxiliary device 40 later, the whole can be integrated and made detachable from the scale 3, or the base 27 can be fixed to the scale 3 in advance and the vertical column 29 can be attached to the scale 3. It is preferable to make it detachable from the base 27.

The auxiliary device 40 includes an auxiliary stand 41 and a guard portion 45.

The auxiliary stand 41 is a right triangular prism-shaped member,
The surface corresponding to the hypotenuse of the right triangle becomes a slope surface 43 that connects the step portion 9 of the weight scale 3 and the floor surface 7. It is preferable that this slope surface 43 is subjected to a non-slip treatment, such as by being covered with rubber. Further, the slope surface 43 is not limited to a flat surface as shown in the figure, but may be a curved surface depending on the elderly or the like.

Two guard parts 45 are provided on both sides of the auxiliary stand 41.
It is composed of a vertical pillar 47 fixed one by one, and horizontal pillars 51 and 53 attached to the vertical pillar 47 in two stages above and below. Each of the horizontal columns 51 and 53 is continuous with each of the horizontal columns 31 and 33 of the handrail portion 25 of the scale body 21. The engagement ring 5 is attached to the end of the lower horizontal column 53 on the scale body 21 side via an L-shaped connecting rod 55.
7 is installed.

The auxiliary device 40 can also be connected to the side of the scale 3. In this case, the handrail section 25 is the display section 1
It will be arranged in parallel to 3.

Note that a flange 44 extends from the lower edge of the surface of the auxiliary stand 41 facing the scale body 21. The rear support leg 6 of the scale body 21 is placed on this flange 44 . Furthermore, the engagement protrusion 34
By fitting the and engagement ring 57 together, the weight scale main body 21 and the auxiliary instrument 40 are removably connected. Of course, both can be fixedly connected.

According to the auxiliary device 40 having such a configuration, an elderly person or the like can easily climb onto the step portion 9 of the weighing scale 3 by climbing along the slope surface 43. On the other hand, this means that the step portion 9 can be made higher, and in this respect, the degree of freedom in designing the weight scale 3 is improved.

At this time, the guard portion 45 of the auxiliary device 40 serves as a handrail for the elderly and the like. However, since the handrail portion 25 of the scale body 21 and the guard portion 45 of the auxiliary device 40 are connected by the engagement protrusion 34 and the engagement ring 57, an elderly person or the like may not grasp onto the grip 32 when measuring weight. However, the load is not transmitted to the guard portion 25. Therefore, accurate weight measurement can be performed.

In addition, when an elderly person or the like leans on the handrail portion 25 and the scale body 21 is tilted, the handrail portion 25
interferes with the guard part 45, and the guard part 45 acts as a stopper for the handrail part 25. Therefore, the scale body 21 will not fall over. In order to ensure that the guard portion 45 functions as a stopper, it is preferable to fix the auxiliary stand 41 to the floor surface. It is also preferable that the auxiliary stand 41 be made wider than the weight scale 3.

Second example FIG. 2 shows an auxiliary device 60 according to another embodiment.

The same members as those in the previous embodiment are given the same reference numerals, and their explanations will be partially omitted.

In this embodiment, the guard portion 6 of the auxiliary instrument 60
5, a human body interference portion 66 having a U-shape in plan view is provided from the horizontal column 51.

When the scale body 21 is tilted, this human body interference part 66 interferes with the body of an elderly person etc.
This prevents it from eventually collapsing.

This human body interference part 66 is connected to the horizontal column 31 of the handrail part 25 so as not to interfere with the body of an elderly person when measuring weight.
It is preferable to arrange it below and/or outside.

Incidentally, if such a human body interfering part is provided in the auxiliary instrument of the first embodiment, it is possible to more reliably prevent the weight scale main body 21 from falling over.

<Functions and effects of the invention> As explained above, the auxiliary device of this invention has the following effects:
An auxiliary platform is provided with a sloped surface that continues from the step to the floor, and is fixed to the auxiliary platform and is placed above the step in a position that does not interfere with the human body during weight measurement, and when the scale is tilted. and a guard portion that interferes with at least one of the handrail or the human body to prevent the scale body from tipping.

With the auxiliary device configured in this manner, an elderly person or the like can climb onto the step portion of the scale by climbing along the rope surface of the auxiliary platform. Therefore, even if the step stool is high, elderly people can climb onto it without difficulty.

In other words, the weighing scale body of this invention is easy to use for elderly people and the like.

In addition, since the guard part supported by the auxiliary stand is placed above the step part of the scale, even if an elderly person leans over the handrail part of the scale body, the guard part will be placed on the handrail. The weighing scale acts as a stopper by interfering with the human body such as the body or the elderly, and prevents the scale body from ultimately falling over.

In other words, the auxiliary device of this invention improves the safety of the scale itself.
