Abstract

PROBLEM TO BE SOLVED: To obtain a shock display method in which a generated shock can be recorded with a pen without using a power supply by a method wherein the pen is attached to a weight and the position to which the weight is turned is recorded. SOLUTION: A weight 3 which comprises a pen 16 is suspended at a fulcrum 1 situated on a scale plate 10 so as to be freely rotatable by a suspension body 17 which is composed of a thin rod. When a shock is generated from the outside in this state, the weight 3 is turned, and the pen 16 records a track 16a on the scale plate 10. Then, the suspension body 17 is returned to its original vertical state immediately after its rotation, and the pen 16 is placed to a state that a shock input level is recorded on the scale plate 10 as the track 16a. That is to say, according to the swing of the weight 3, the track is recorded with the pen 16, and the level of the shock can be displayed without using a power supply.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock display method and a shock sensor, and more particularly to a novel improvement for recording a generated shock with a pen without using a power supply.

[0002]

2. Description of the Related Art For example, a structure shown in FIG. 3 has been conventionally used as this kind of shock sensor. That is, the weight 3 is swingably provided on the support portion 1 having the fulcrum via the suspension 2.
Is provided with a strain gauge 4. A power source 5 is connected to the strain gauge 4, and an output signal 4 a of the strain gauge 4 is input to a digital display 6 and displayed. Accordingly, when a shock occurs, the weight 3 rotates together with the suspension body 2 as shown in FIGS. 3A and 3B, so that the output signal 4a from the strain gauge 4 during this rotation.
Is converted into a display signal by a processing circuit (not shown) in the display 6 and is digitally displayed.

[0003]

Since the conventional shock sensor is configured as described above, there are the following problems. That is, in the above-described conventional configuration, since the shock signal, which is the output signal obtained from the strain sensor, is displayed on the display, it is impossible to perform the display without using the power supply.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, the present invention provides a shock display method and a shock sensor in which a generated shock is recorded by a pen without using a power supply. The purpose is to:

[0005]

A shock display method according to the present invention is directed to a shock sensor for detecting a shock by means of a weight suspended via a suspension at a fulcrum on a scale plate. This is a method of recording the position where is turned.

More specifically, there is a method using a spring as the suspension body.

More specifically, there is a method using a thin rod as the suspension.

A shock sensor according to the present invention is a shock sensor for detecting a shock by a weight suspended from a fulcrum on a scale plate via a suspension body. The shock sensor has a pen on the weight, and the pen is moved by the movement of the weight. Is moved and its locus is recorded on the scale plate.

[0009] More specifically, the suspension body is constituted by a spring.

[0010] More specifically, the suspension body is formed of a thin rod.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a shock display method and a shock sensor according to the present invention will be described below in detail with reference to the drawings. The same or equivalent parts as those in the conventional example will be described with the same reference numerals. In FIG. 1, reference numeral 1 denotes a fulcrum located on the scale plate 10, and the fulcrum 1 has a weight 3 having a pen 16 suspended from a spring or a thin rod as shown in FIG. The body 17 is rotatably suspended.

Next, the operation will be described. First, when a shock is applied from the outside in the state of FIG. 1A, the weight 3 moves and rotates as shown in FIG.
The pen 16 mounted on the scale plate 10 records the locus 16a. The suspension body 17 immediately returns to the original vertical state after the rotation, but is configured so that the pen 16 records the shock input level on the scale plate 10 as the locus 16a as shown in FIG. I have.

[0013]

Since the shock display method and the shock sensor according to the present invention are configured as described above, the following effects can be obtained. That is, since the locus of the weight can be recorded by the pen in accordance with the swing of the weight, the shock level can be displayed without requiring any power supply, and an inexpensive shock sensor can be provided.
