Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acceleration / deceleration visual recognition apparatus and an acceleration / deceleration visual recognition method capable of visually recognizing a value of a horizontal component of acceleration or deceleration.

[0002]

2. Description of the Related Art Conventionally, in a vehicle or the like, a device described in Japanese Utility Model Publication No. 58-32415 (hereinafter, referred to as a device) that enables a driver to grasp the value of the acceleration or deceleration of the vehicle at that time is known. The invention is described in Japanese Utility Model Laid-Open Publication No. 57-42909 (hereinafter referred to as “device B”), and Japanese Patent Publication No. Hei 5-5016.
No. 06 (Japanese Patent Application No. 2-515116) (hereinafter referred to as "device C") is known. The basic configuration or principle of these devices is as follows.

The basic idea of the device of the invention is that a mechanism that rotatably supports a point other than the center of gravity of the weight and provides a pointer at a position other than the rotation axis of the weight is: One that is arranged in the traveling direction of the car or the like and the left or right direction of the car or the like ”. With this configuration,
In a state where no acceleration or deceleration is applied, the pointer indicates a predetermined reference position (hereinafter, referred to as “zero point”) on a scale fixed to an automobile or the like. Next, when acceleration or deceleration acts on this device, an inertial force acts on the center of gravity of the weight in a direction opposite to the direction of acceleration or the like, due to the acceleration or the like.
For this reason, the weight rotates about the rotation axis as the rotation center, and the pointer also rotates accordingly. The device of the present invention attempts to read the value of acceleration or the like by reading the movement angle or movement amount of the pointer with a scale.

On the contrary, the basic principle of the device of the invention B is opposite to that of the invention A in that the pointer is fixed to an automobile or the like, and the scale is constituted by the same mechanism as that of the invention A. is there. With this configuration, in a state where no acceleration or deceleration is applied, the zero point of the scale member matches the position of the fixed pointer. Next, when acceleration or deceleration acts on this device, an inertial force acts on the center of gravity of the weight in a direction opposite to the direction of acceleration or the like, due to the acceleration or the like. For this reason, the weight rotates about the rotation axis as the rotation center, and the scale member is accompanied by the rotation. The device of the invention 2 attempts to read the value of acceleration or the like by reading the movement angle and movement amount of the scale member with a pointer.

The basic principle of the device of the invention C is that "a truncated cone-shaped hollow chamber is filled with a liquid and air bubbles are enclosed, and an electric resistance sensor is arranged on a flat ceiling portion of the hollow chamber". . With this configuration, when acceleration or deceleration acts on the device, the bubbles move in contact with the flat ceiling portion of the hollow chamber due to the acceleration or the like. The resistance sensor detects the change, and the Wheatstone bridge circuit converts the change in current into a change in resistance. Based on this, an arithmetic circuit or the like calculates and outputs an acceleration value.

[0006]

However, the above-described conventional apparatus has the following disadvantages.

First, the device of the invention (a) needs to be stationary at zero when no acceleration or the like is applied, and it is necessary to rotate according to the acceleration or the like when applied. In response to the former requirement, the weight must be heavier than a certain amount. This is because if the weight is light, even if a slight force is applied, the pointer largely swings. On the other hand, in response to the latter requirement, the weight must be lighter than a certain amount. This is because if the weight is heavy, the sensitivity to move in response to the inertial force is reduced. Therefore, the device of this invention must solve the conflicting demands of the above, and adopting an intermediate value can only provide a halfway solution to either of the requirements. There was a problem.

Further, the device of the invention A is basically a "pendulum" mechanism, so once it swings to one side, it also swings to the opposite side by its reaction, and then performs a pendulum motion (vibration). Therefore, the value indicated by the pointer is inaccurate and has little meaning unless this vibration is attenuated and returned to zero.

Further, as described above, the device of the invention (2)
Since only the fixed member and the movable member in the device of the invention A are reversed and the basic principle is exactly the same as that of the device of the invention A, it has exactly the same disadvantages as those of the device of the invention A described above. doing.

Although the device of the invention C is considered to be capable of quantitatively measuring the acceleration value and the like, it is over-spec (excessively high quality) as an accessory for an automobile or the like. Since an electronic circuit or the like is required, the price is extremely high, and there is a drawback that it is hardly accepted by consumers as accessory articles for automobiles and the like. In addition, a power supply for driving sensors and electronic circuits is indispensable, and if it is fixed to an instrument panel of an automobile or the like, the power supply can be secured by a battery for an automobile. There is a problem that it is necessary to carry batteries and the like.
In addition, there is also a problem in that the device has precise components such as a sensor and an electronic circuit, and thus has a high probability of failure.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of an acceleration / deceleration visual recognition device according to the present invention will be described in detail with reference to the drawings.

(1) First Embodiment FIG. 1 is a diagram showing a configuration of an acceleration / deceleration visual recognition device according to a first embodiment of the present invention. FIG. 1 (A) is a top view and FIG.
(B) has shown the sectional view, respectively.

As shown in FIG. 1, the acceleration / deceleration visual recognition device 101 includes a substantially disc-shaped value visual recognition unit 11 and a direction visual recognition unit 21.

The value recognition unit 11 includes a bottom plate 111 and an upper plate 11.
2 has a substantially one-convex lens-like hollow airtight container, a holding liquid 113 filled in the container, and a bubble 114 sealed in the holding liquid 113.

The bottom plate 111 is made of a transparent material such as glass or transparent acrylic resin, and is a member formed in a substantially circular flat plate shape. On the lower surface of the bottom plate, a substantially concentric acceleration / deceleration value scale 115 as shown in FIG. 1A and a cross-shaped reference line 117 forming an angle of 90 degrees with each other are formed by drawing, press molding or engraving. Is formed. Also,
The upper surface plate 112 is made of a transparent material such as glass or transparent acrylic resin, and has a circular horizontal projection shape, a convex spherical shape on the upper surface, and a partial spherical shell shape with a concave spherical surface on the lower surface (inner surface). . The bottom plate 111 and the top plate 112 are bonded to each other at their outer peripheral edges with an adhesive or the like. A substantially annular convex portion is formed on the outer peripheral edge of the bottom plate 111. The holding liquid 113 is a transparent liquid such as water or alcohol.

The direction visually recognizing part 21 is a substantially dish-shaped container 211.
A magnetic needle shaft support 212 disposed at the center of the inner bottom surface of the container 211, a magnetic needle shaft 213 rotatably supported by the magnetic needle shaft support 212, and a magnetic needle 214 attached to the magnetic needle shaft 213. Have.

The above-mentioned container 211 is made of a synthetic resin material or a metal material, and has a substantially circular flat plate-like bottom portion, and a substantially cylindrical side portion vertically erected from the outer peripheral edge of the bottom portion. It is an open member. An azimuth scale 2 for dividing a circle into eight as shown in FIG.
15 are formed by drawing, press molding, engraving, or the like. Of these azimuth scales, an angle of 90
The four graduations are set to match the reference line 117 described above.

In the vicinity of the upper end of the side of the container 211,
A fitting groove is formed in which the annular convex portion on the outer periphery of the bottom plate 111 of the value recognition portion 11 can be fitted. Magnetic needle shaft support 21
2 is formed in a substantially cylindrical shape whose upper end face is closed,
An opening for inserting the magnetic needle shaft 213 is formed at the center of the closed upper end surface. The lower end of the magnetic needle shaft 213 is formed in a pointed needle shape, and the magnetic needle shaft 213 is supported at one point by the lower end, and the periphery of the magnetic needle shaft 213 is
And is rotatable. Further, the magnetic needle shaft 212
A protrusion for preventing the magnetic needle shaft 213 from being detached from the magnetic needle shaft support portion 212 is provided in the middle of. Magnetic needle 21
Reference numeral 4 denotes an arrow-shaped member having an N magnetic pole and an S magnetic pole.

The acceleration / deceleration visual recognition device 101 has the above-mentioned components, and the acceleration / deceleration visual recognition device 101 is provided above the direction visual recognition unit 21.
1 are stacked. Next, the operation of the acceleration / deceleration visual recognition device 101 will be described.

The above-described direction visual recognition section 21 has the same function as a normal magnetic needle type compass. Further, since the top plate 112, the holding liquid 113, and the bottom plate 111 of the value visual recognition unit 11 are transparent, the user can easily visually recognize the magnetic needle 214 from above the acceleration / deceleration visual recognition device 101. Therefore, the user can hold the whole of the acceleration / deceleration visual recognition device 101 in his / her hand and adjust the rotation as needed, thereby setting the N
The magnetic pole may be aligned with the “north” position of the azimuth scale 215. If this state is reached, it means that the azimuth of the entire acceleration / deceleration visual recognition device 101 has been accurately adjusted.

When no acceleration or deceleration is applied, the value recognition unit 11 has the same function as a normal bubble level. Therefore, next, when the user holds the entire acceleration / deceleration visual recognition device 101 in his hand and appropriately adjusts the inclination, the center of the bubble 114 is viewed from above.
The center point where the cross-shaped reference line 117 intersects (hereinafter, referred to as “reference position”) can be matched. When this state is reached, it means that the entire acceleration / deceleration visual recognition device 101 is in an accurate horizontal state.

When the user checks the acceleration / deceleration visual recognition device 1 in the above state.
01, the acceleration / deceleration viewing device 10
When acceleration or deceleration acts on 1, the bubble 114 in the value recognition unit 11 moves in the same direction as the horizontal component vector of the applied acceleration or deceleration. The concentric acceleration / deceleration value scale 115 has a unit of acceleration or deceleration value, for example, km / h / sec (h: time, sec: second), g (= 9.80 m / sec ² ), or gal. (= 1c
Any one of the numerical values in m / sec ² ) or a combination thereof is described. Therefore, by reading the acceleration / deceleration value scale 115 near the position where the bubble 114 has moved, the user can visually recognize the value of the horizontal component of the acceleration or deceleration at that time. If the direction in which the bubble 114 has moved from the reference position is read from the azimuth scale 215 of the direction recognition unit 21, the direction of the horizontal vector of the acceleration or deceleration at that time can be visually recognized. If the angle (in units of 360 degrees) is also described on the azimuth scale 215, the direction of acceleration / deceleration can be visually recognized quantitatively.

As described above, the reason why the bubble 114 moves in the same direction as the horizontal component vector of the acceleration / deceleration when the acceleration / deceleration is applied is that the retained liquid 113 in the value recognition unit 11 is caused by the acceleration / deceleration. The inertial force acts in the direction opposite to the direction of acceleration / deceleration. Therefore, the retained liquid 113 tends to move in the direction opposite to the direction of the acceleration / deceleration as a whole.
Since the bubbles 114 are not independent components of the holding liquid 113 but are a kind of cavity formed in the holding liquid 113, the bubbles 114 are pushed in the opposite direction by the above-described movement of the holding liquid 113. That is, by this, the bubble 114 becomes
It will move in the same direction as the acceleration / deceleration direction,
Since 12 is maintained in the horizontal direction, it eventually moves in the same direction as the direction of the horizontal component vector of the acceleration / deceleration. The movement of the bubble 114 is very sensitive, and moves almost instantaneously from the reference position by a distance corresponding to the value of the acceleration or the deceleration during the period in which the acceleration or the deceleration is applied.

The bubbles 114 always move upward in the holding liquid 113 by buoyancy. Therefore, when the horizontal state is maintained and no acceleration or deceleration is applied, it is determined that the bubble is located at the reference position, which is the highest point of the inner surface of the upper surface plate 112, from the balance of the physical force. 114 is the most stable state. Further, the retained liquid 113 serves as an appropriate damper (braking means) for the movement of the bubble 114, and has a function of preventing the bubble 114 from vibrating around the reference position. Therefore, when acceleration or deceleration stops working,
The bubble 114 returns to the reference position almost instantaneously and does not vibrate near the reference position.

As described above, according to the acceleration / deceleration visual recognition device 101 of the first embodiment, (1) since the configuration is simple and no electric circuit or power supply is required, the cost is low and the device is portable. It is easy and does not break down. (2) The response to acceleration / deceleration (response) is quick and does not generate vibration, so that visual recognition is easy and accurate. (3) Since the value recognition portion 11 is formed in a substantially uniconvex lens shape as a whole, the bubble 11
4 and each scale are enlarged, so that the visual recognition is easier. There is an advantage.

(2) Second Embodiment Next, a second embodiment of the present invention will be described. FIG.
FIG. 2A is a diagram illustrating a configuration of an acceleration / deceleration visual recognition device according to a second embodiment of the present invention. FIG. 2A is a top view, and FIG.
Shows cross-sectional views, respectively.

As shown in FIG. 2, the acceleration / deceleration visual recognition device 102 includes a substantially columnar value visual recognition unit 12 and a substantially disk-shaped direction visual recognition unit 22.

The value recognition unit 12 includes a cylindrical body 121 and a top plate 1.
22, a holding liquid 123 filled in the container, a floating body 124 sealed in the holding liquid 123, and a mooring member 1 for mooring the floating body 124.
26.

The above-mentioned cylindrical body 121 is made of a transparent material such as glass or transparent acrylic resin, and has a substantially circular flat bottom and a substantially cylindrical side vertically set up from the outer peripheral edge of the bottom. , The upper part of which is open. This cylindrical body 12
At the center of the inner bottom surface of the anchor 1, a mooring member supporting portion 121a having a substantially spherical empty space is provided. Also, the top plate 122
Consists of a transparent material such as glass or transparent acrylic resin,
The horizontal projection shape is circular, the upper surface is formed in a convex spherical shape, and the lower surface is formed in a substantially uniconvex lens shape having a planar shape. On the lower surface of the upper surface plate 122, a substantially concentric acceleration / deceleration value scale 125 as shown in FIG. 2A and a cross-shaped reference line 127 forming an angle of 90 degrees with each other are drawn or press-formed or engraved. And the like. Further, the vicinity of the upper end of the side portion of the cylindrical body 121 and the upper surface plate 122 are bonded to each other at an outer peripheral edge thereof with an adhesive or the like. A substantially annular concave portion is formed on the outer peripheral edge of the lower portion of the cylindrical body 121, and can be stacked on the direction recognition portion 22.

The holding liquid 123 is a transparent liquid such as water or alcohol. Further, a fluorescent colorant is mixed in the holding liquid 123.

The floating body 124 is made of a material having a sufficiently small specific gravity, for example, wood or the like, compared to the retained liquid 123, and is formed in a spheroidal shape having little underwater resistance in the floating body moving direction. In the center of the lower part of the floating body 124, a mooring member 126
Are joined. The mooring member 126 is a wire-like member made of a synthetic resin material or a metal material, and has a predetermined rigidity. The lower end 126a of the mooring member 126 is formed in a spherically swollen shape, and fits into a substantially spherical empty space of the mooring member supporting portion 121a at the center of the inner bottom surface of the cylindrical body 121 to form a universal joint-like mechanism. doing.
With such a configuration, the floating body 124 is
It can swing around the center.

The direction visually recognizing part 22 is a substantially dish-shaped container 221.
A magnetic needle shaft support 222 disposed at the center of the inner bottom surface of the container 221, a magnetic needle shaft 223 rotatably supported by the magnetic needle shaft support 222, and a magnetic needle 224 attached to the magnetic needle shaft 223. Have. An orientation scale 225 for dividing a circle into eight as shown in FIG. 2A is formed on the bottom upper surface of the container 221 by drawing, press molding, engraving, or the like. Among these azimuth scales, four scales forming an angle of 90 degrees with each other are set so as to match the above-mentioned reference line 127. The configuration and operation of the direction visual recognition unit 22 are based on the acceleration / deceleration visual recognition device 101 of the first embodiment.
Since the configuration and operation of the direction visual recognition unit 21 are the same, description thereof will be omitted.

Next, the operation of the acceleration / deceleration visual recognition device 102 will be described.

The above-described direction visual recognition unit 22 has the same function as a normal magnetic needle type compass. Further, since the upper surface plate 122, the holding liquid 123, and the cylindrical body 121 of the value visual recognition unit 12 are transparent, the user can easily visually recognize the magnetic needle 224 from above the acceleration / deceleration visual observation device 102. Therefore, the user can hold the entire acceleration / deceleration visual recognition device 102 in his / her hand and adjust the rotation appropriately, so that the N magnetic pole of the magnetic needle 224 can be matched with the “north” position of the azimuth scale 225. In this state, it means that the azimuth of the entire acceleration / deceleration visual recognition device 102 has been accurately adjusted.

When no acceleration or deceleration is applied, the value recognition unit 12 has the same function as a normal bubble level. Therefore, the user then holds the entire acceleration / deceleration visual recognition device 102 in his / her hand and adjusts the inclination appropriately, so that the center of the floating body 124 intersects the center point of the cross-shaped reference line 127 (hereinafter referred to as “reference position ").) When this state is reached, it means that the entire acceleration / deceleration visual recognition device 102 has been placed in an accurate horizontal state.

When the user checks the acceleration / deceleration viewing device 1
02, the acceleration / deceleration visual recognition device 10
When the acceleration or deceleration acts on 2, the floating body 124 in the value recognition unit 12 moves in the same direction as the horizontal component vector of the applied acceleration or deceleration. The concentric acceleration / deceleration value scale 125 has the acceleration / deceleration value scale 1 of the first embodiment.
Numerical values similar to 15 are described. Therefore, if the user reads the acceleration / deceleration value scale 125 near the position where the floating body 124 has moved, the user can visually recognize the value of the horizontal component of the acceleration or deceleration at that time. Also,
The direction in which the floating body 124 has moved from the reference position is determined by the direction recognition unit 22.
By reading from the azimuth scale 225, the direction of the horizontal vector of the acceleration or deceleration at that time can be visually recognized. If the angle (in units of 360 degrees) is also described in the azimuth scale 225, the direction of acceleration / deceleration can be visually recognized quantitatively.

As described above, the reason why the floating body 124 moves in the same direction as the horizontal component vector of the acceleration / deceleration when the acceleration / deceleration acts is completely different from the case of the acceleration / deceleration visual recognition device 101 of the first embodiment. Similarly, with the acceleration / deceleration, an inertial force acts on the retained liquid 123 in the value recognition unit 12 in a direction opposite to the direction of the acceleration / deceleration, and the retained liquid 12
3 is to move in the direction opposite to the direction of acceleration / deceleration as a whole.
Is displaced in the opposite direction by the above movement of the holding liquid 123. For this reason, the floating body 124 moves in the same direction as the direction of the acceleration / deceleration, and the entire apparatus is maintained in the horizontal direction, so that the floating body 124 eventually moves in the same direction as the direction of the horizontal component vector of the acceleration / deceleration. It becomes.

The floating body 124 always moves upward in the retained liquid 123 by buoyancy. Therefore, when the horizontal state is maintained and no acceleration or deceleration is applied, the floating body 124 may be located at the reference position that is the highest point from the viewpoint of the balance of the physical force.
Is the most stable state. Further, the holding liquid 12
Reference numeral 3 designates an appropriate damper (braking means) for the movement of the floating body 124 and the mooring member 126, and has a function of preventing the floating body 124 from vibrating around the reference position. For this reason, when acceleration or deceleration stops acting, the floating body 1
24 returns to the reference position promptly and does not vibrate near the reference position.

As described above, according to the acceleration / deceleration visual recognition device 102 of the second embodiment, (1) since the configuration is simple and no electric circuit or power supply is required, the cost is low and the device is portable. It is easy and does not break down. (2) The response to acceleration / deceleration (response) is quick and does not generate vibration, so that visual recognition is easy and accurate. (3) Since the upper surface plate 122 of the value viewing portion 12 is formed in a substantially one-convex lens shape, when viewed from above by the user, the floating body 124 and the respective scales are enlarged, and the visibility is easier. (4) Since the fluorescent coloring agent is mixed in the holding liquid 123 of the value recognition unit 12, the floating body 1
24 is easier to see. There is an advantage.

(3) Third Embodiment Next, a third embodiment of the present invention will be described. FIG.

Is filled with a putty or the like for preventing liquid leakage.

The upper plate 132 is made of a transparent material such as glass or transparent acrylic resin, and is formed in a substantially circular flat plate shape. Also, near the upper end of the side of the cylindrical body 130,

The configuration and operation of 3 are the same as the configuration and operation of the direction visual recognition unit 21 in the acceleration / deceleration visual recognition device 101 of the first embodiment, and a description thereof will be omitted.

Next, the operation of the acceleration / deceleration visual recognition device 103 will be described.

The above-described direction visual recognition section 23 has the same function as a normal magnetic needle type compass. Further, since the upper surface plate 132, the holding liquid 133, and the cylindrical body 130 of the value visual recognition unit 13 are transparent, the user can easily visually recognize the magnetic needle 234 from above the acceleration / deceleration visual recognition device 103. Therefore, the user can hold the entire acceleration / deceleration visual recognition device 103 in his / her hand and adjust the rotation appropriately, so that the N magnetic pole of the magnetic needle 234 can be matched with the “north” position of the azimuth scale 235. In this state, it means that the direction of the entire acceleration / deceleration visual recognition device 103 has been accurately adjusted.

When no acceleration or deceleration is applied, the value recognition unit 13 has the same function as a normal level. Therefore, next, this acceleration / deceleration visual recognition device 103
The user can hold the entire body in his hand and adjust the inclination appropriately, so that the center of the rolling element 134 can be made to coincide with the center point where the cross-shaped reference line 137 intersects (hereinafter, referred to as “reference position”). . When this state is reached, it means that the entire acceleration / deceleration visual recognition device 103 has been accurately placed in a horizontal state.

When the user checks the acceleration / deceleration visual recognition device 1
03, the acceleration / deceleration viewing device 10
When acceleration or deceleration acts on 3, the rolling element 134 in the value recognition unit 13 moves in the direction opposite to the horizontal component vector of the applied acceleration or deceleration. On the concentric acceleration / deceleration value scale 135, the same numerical values as those on the acceleration / deceleration value scale 115 of the first embodiment are described. Therefore, by reading the acceleration / deceleration value scale 135 near the position where the rolling element 134 has moved, the user can visually recognize the value of the horizontal component of the acceleration or deceleration at that time.
When the direction in which the rolling element 134 has moved from the reference position is read from the azimuth scale 235 of the direction recognition unit 23, the direction of the horizontal vector of the acceleration or deceleration at that time is regarded as the direction opposite to the moving direction of the rolling element 134. You can see it.
If the angle (in units of 360 degrees) is also described on the azimuth scale 235, the direction of acceleration / deceleration can be visually recognized quantitatively.

The reason why the rolling element 134 moves in the direction opposite to the horizontal component vector of the acceleration / deceleration when the acceleration / deceleration acts as described above is that the value recognition unit 13
Inertial force acts on the rolling element 134 in the direction opposite to the direction of acceleration / deceleration, and the rolling element 134 rolls in the direction opposite to the direction of acceleration / deceleration. Since it is maintained, it eventually moves in the direction opposite to the direction of the horizontal component vector of the acceleration / deceleration.

In addition, the rolling element 134 always moves downward in the retained liquid 133 due to gravity.
Therefore, when the horizontal state is maintained and no acceleration or deceleration is applied, it is determined that the rolling element 13 is located at the reference position which is the lowest point from the viewpoint of the balance of the physical force.
4 is the most stable state. Also, the holding liquid 1
Reference numeral 33 denotes an appropriate damper (braking means) for the movement of the rolling element 134, and has a function of preventing the rolling element 134 from vibrating around the reference position. Therefore, when the acceleration or the deceleration stops acting, the rolling element 134 quickly returns to the reference position and does not vibrate near the reference position.

As described above, according to the acceleration / deceleration visual recognition device 103 of the third embodiment, (1) since the configuration is simple and no electric circuit or power supply is required, the price is low and the device is portable. It is easy and does not break down. (2) The response to acceleration / deceleration (response) is quick and does not generate vibration, so that visual recognition is easy and accurate. (3) Since the upper surface plate 132 of the value viewing portion 13 is formed in a substantially one-convex lens shape, when viewed from above by the user, the rolling elements 134 and the respective scales are enlarged, so that the visibility is easier. (4) Since the fluorescent coloring agent is mixed in the holding liquid 133 of the value viewing portion 13, when the user sees from above, the rolling elements 134 can be more easily viewed. (5) Since a paint or a thin film having high light reflectivity is applied or stuck on the upper surface of the inner bottom surface of the cylindrical body 130, it is easier for the user to visually recognize the rolling elements 134 when viewed from above. Become. There is an advantage.

(4) Fourth Embodiment Next, a fourth embodiment of the present invention will be described. FIG.
FIG. 4A is a diagram showing a configuration of an acceleration / deceleration visual recognition device according to a fourth embodiment of the present invention. FIG. 4A is a front view, and FIG.
Shows a side sectional view near the center, and FIG. 4C shows a top view.

As shown in FIG. 4, this acceleration / deceleration visual recognition device 104 is a value visual recognition unit 1 capable of visually confirming the acceleration / deceleration in one direction.
4 is provided.

The value recognition portion 14 has a substantially “U” -shaped support frame portion 141, an arc-shaped member 142 provided between two side portions of the support frame portion 141, and externally fitted to the arc-shaped member 142. The sliding member 144 is provided.

The support frame 141 is made of a synthetic resin material, a metal material, wood, stone, or the like, and has a substantially rectangular flat bottom portion and a substantially rectangular flat shape vertically set up from two edges of the bottom portion. "Ko" with two sides
It is a letter-shaped member. As shown in FIG. 5C, a substantially scaled acceleration / deceleration value scale 145 perpendicular to the direction in which the arc-shaped member 142 extends is drawn, press-formed, or engraved on the upper surface of the bottom of the support frame 141. And the like.

The arc-shaped member 142 is a wire-shaped member made of a synthetic resin material or a metal material, has a predetermined rigidity,
It is formed in a concave curve shape, for example, in an arc shape that is convex downward.

The sliding member 144 is made of a synthetic resin material or a metal material and is formed in a spheroidal shape, and has a substantially arc-shaped opening through which the arc-shaped member 142 can be inserted in the axial direction. With such a configuration, the sliding body 144 is configured to be slidable along the arc-shaped member 142. Also,
The collimation line 14 extends around the center of the sliding body 144.
4a is formed by drawing, press molding, engraving, or the like.

Next, the operation of the acceleration / deceleration visual recognition device 104 will be described.

First, the longitudinal direction of the acceleration / deceleration visual recognition device 104 is adjusted to match the direction of the acceleration / deceleration. next,
The level of the acceleration / deceleration visual recognition device 104 is adjusted by a level or the like so as to be in an accurate horizontal state.

The user checks the acceleration / deceleration visual recognition device 1 in the above state.
04, the acceleration / deceleration viewing device 10
When the acceleration or deceleration acts on the sliding member 144, the sliding member 144 of the value visual recognition unit 14 causes the arc-shaped member 142 to be in the opposite direction to the horizontal component vector of the applied acceleration or deceleration.
Move along. The scale-like acceleration / deceleration value scale 145 describes the same numerical values as the acceleration / deceleration value scale 115 of the first embodiment. For this reason, the user can use the sliding body 144.
By reading the acceleration / deceleration value scale 145 near the position where has moved, the value of the horizontal component of the acceleration or deceleration at that time can be visually recognized quantitatively.

As described above, the reason why the sliding body 144 moves along the arc-shaped member 142 in the direction opposite to the horizontal component vector of the acceleration / deceleration when the acceleration / deceleration acts is that the value visualization unit is associated with the acceleration / deceleration. Inertial force acts on the sliding member 144 in the direction opposite to the direction of acceleration / deceleration, and the sliding member 144 slides in the direction opposite to the direction of acceleration / deceleration. Since it is maintained, it eventually moves in the direction opposite to the direction of the horizontal component vector of the acceleration / deceleration.

The sliding body 144 always moves downward on the arc-shaped member 142 by gravity.
Therefore, when the vehicle is maintained in the horizontal state and no acceleration or deceleration is applied, it may be determined that the slider is located at the reference position (the position on 145a), which is the lowest point, based on the balance of the physical force. The moving body 144 is in the most stable state. The sliding frictional resistance with the arc-shaped member 142 becomes an appropriate damper (braking means) for the movement of the sliding body 144, and prevents the sliding body 144 from vibrating around the reference position (a position on the 145a). It has the function of doing. For this reason, when acceleration or deceleration stops acting, the sliding body 14
4 quickly returns to the reference position (the position on 145a) and does not vibrate near the reference position.

As described above, according to the acceleration / deceleration visual recognition device 104 of the fourth embodiment, (1) since the configuration is simple and no electric circuit or power supply is required, the cost is low and the device is portable. It is easy and does not break down. (2) The response to acceleration / deceleration (response) is quick and does not generate vibration, so that visual recognition is easy and accurate. (3) Since the collimation line 144a is formed around the center of the sliding body 144, when the user sees from above, the sliding body 1
The visual recognition of 44 becomes easier. There is an advantage.

(5) Fifth Embodiment Next, a fifth embodiment of the present invention will be described. FIG.
FIG. 5A is a diagram showing a configuration of an acceleration / deceleration visual recognition device according to a fifth embodiment of the present invention. FIG. 5A is a front view, and FIG.
Shows side views, respectively.

As shown in FIG. 5, the acceleration / deceleration visual recognition device 105 is a value visual recognition unit 1 capable of visually confirming the acceleration / deceleration in one direction.
5 is provided.

The value recognition unit 15 includes a support base 150 and a substantially “U” -shaped tube 151 supported by the support base 150.
And working liquids 153a and 153b sealed in the tube 151.

The above-mentioned tube 151 is a member made of a transparent material such as glass or transparent acrylic resin, and has a circular or square cross section and a substantially “B” side shape. As shown in FIG. 5 (A), a substantially scaled acceleration / deceleration value scale 155 perpendicular to the extension axis direction of the pipe is drawn, press-formed or engraved on the side surface of the pipe 151. Is formed.

The one working liquid 153a is a liquid mixed with a fluorescent coloring agent. Also, the other working liquid 153b
Is a transparent liquid having a lower specific gravity than the working liquid 153a.

Next, the operation of the acceleration / deceleration visual recognition device 105 will be described.

First, the longitudinal direction of the acceleration / deceleration visual recognition device 105 is adjusted so as to match the direction of the acceleration / deceleration. next,
The level of the acceleration / deceleration visual recognition device 105 is adjusted by a level or the like so as to be in an accurate horizontal state.

The user checks the acceleration / deceleration visual recognition device 1 in the above state.
05, the acceleration / deceleration viewing device 10
5, when the acceleration or deceleration acts on the working liquid 153a.
Of the two liquid surfaces, the front liquid surface descends in the direction of the horizontal component vector of the applied acceleration or deceleration,
The liquid level at the rear rises. Scale-like acceleration / deceleration value scale 155
, The same numerical values as the acceleration / deceleration value scale 115 of the first embodiment are described. For this reason, if the user reads the acceleration / deceleration value scale 155 near the position where the liquid level has dropped, for example, the user can visually recognize the value of the horizontal component of the acceleration or deceleration at that time.

As described above, the reason why the level of the working liquid 153a moves downward or upward in a predetermined direction with respect to the horizontal component vector of the acceleration / deceleration when the acceleration / deceleration acts is as follows. 15 working liquids 153a and 1
An inertial force acts on the 53b in the direction opposite to the direction of the acceleration / deceleration, and the working liquids 153a and 153b try to move in the direction opposite to the direction of the acceleration / deceleration, so that the entire apparatus is maintained in the horizontal direction. Therefore, in the end, the liquid level in front drops in the direction of the horizontal component vector of the acceleration / deceleration,
The liquid level at the rear will rise.

The working liquids 153a and 153b are
In the tube 151, it always tries to move downward by gravity. Therefore, when the horizontal state is maintained and no acceleration or deceleration is applied, from the balance of the physical force, the reference position which is the same liquid level position as the center of the working liquids 153a and 153b is determined from the balance of the physical force. Positioning at 155a is the most stable state for both working liquids 153a and 153b. In addition, both working liquids 153a and 153a
The sliding frictional resistance between 3b and the inner surface of the pipe is determined by
It acts as an appropriate damper (braking means) for the movements of a and 153b, and serves to prevent the working liquids 153a and 153b from vibrating around the reference position 155a. Therefore, when acceleration or deceleration stops working,
The liquid levels of the working liquids 153a and 153b quickly return to the reference position 155a, and do not vibrate near the reference position 155a.

As described above, according to the acceleration / deceleration visual recognition device 105 of the fifth embodiment, (1) since the configuration is simple and no electric circuit or power supply is required, the price is low and the device is portable. It is easy and does not break down. (2) The response to acceleration / deceleration (response) is quick and does not generate vibration, so that visual recognition is easy and accurate. (3) While the working liquid 153a is mixed with the fluorescent colorant, the working liquid 153b is a transparent liquid, so that it is very easy to visually check the liquid level between the two. There is an advantage.

As described above, the acceleration / deceleration visual recognition device of each of the above embodiments has a sufficient acceleration / deceleration visual recognition effect by itself. However, for example, when the mobile body moves diagonally upward when used in a mobile body such as an automobile, the device itself or a user holding the device inclines together with the mobile body. In such a state, it may be difficult to obtain an accurate value only by reading the scale value of the acceleration / deceleration value viewing device.

In order to solve the above-mentioned problem, it is only required that the acceleration / deceleration visual recognition device can always be kept horizontal.
An example of an apparatus for this will be described below.

FIG. 6 is a perspective view showing the configuration of a mounting device for mounting the acceleration / deceleration visual recognition device of each of the above embodiments on a vehicle. 7 is a diagram showing the configuration of the mounting device shown in FIG. 6, in which FIG. 7 (A) shows a top view and FIG. 7 (B) shows a side view.

As shown in these figures, this mounting device 3
00 is a mounting part 301 that can be mounted on the mounting location, a tilt adjustment part 302 that can be adjusted to a horizontal state when mounted, a horizontal maintaining part 303 that can always maintain a horizontal state by tilting a moving body or the like, The acceleration / deceleration visual recognition device holding unit 304 capable of holding the above-described acceleration / deceleration visual recognition device is provided.

The mounting portion 301 is a substantially disk-shaped disk-shaped portion 31.
1 and a substantially “U” -shaped gripping portion 312. A holding projection 314 for holding an adjustment plate 321 to be described later is formed on the disc-shaped portion 311. In addition, the gripper 3
12 is provided with a fixing bolt 313 for fixing to a mounting portion such as a plate portion.

The tilt adjusting section 302 is provided with the disc-shaped section 3 described above.

The horizontal maintaining portion 303 is swingable by a support column 331 erected on the adjustment plate 321, a substantially annular support ring 332 supported by the support column 331, and the support ring 332. The movable ring 333 is supported. The movable ring 333 is provided with two substantially columnar rotating pins 333a on both sides so as to pass through the center of the ring. In addition, these rotation pins 333a are provided on the support ring portion 332.
Semi-cylindrical support recess 33 for swingably supporting
2a is formed. In addition, the movable ring 333 has a rotation pin 343 provided on a holding portion main body 341 described later.

3b is formed.

Have been. The holding section main body 341 is made of a metal material or the like, and is configured to be heavy.

The axial direction of 3 and the axial direction of the rotation pin 333a are set to be orthogonal to each other.

With the above configuration, the mounting device 3
When 00 is tilted, the holding portion main body 341 is directed to a vertical direction because it is a kind of weight. This movement corresponds to the rotation pin 343, the movable ring 333, and the rotation pin 3
It is followed by the movement of 33a. Therefore, the upper surface of the holding concave portion 342 of the holding portion main body 341 is always kept horizontal.

In the initial state, when the mounted part such as the moving body is inclined in the initial state, the three adjusting screws 322 of the inclination adjusting part 302 are moved in and out to adjust the horizontal state. .

However, as described above, when acceleration or deceleration acts, inertial force acts on everything. The holding section main body 341 is no exception, and even if the weight is extremely large, the upper surface of the holding recess 342 is inclined by a small angle due to the addition of inertia. For this reason, this mounting device 3
When the acceleration / deceleration visual recognition device is mounted at 00, it is preferable to set the acceleration / deceleration value scale of the acceleration / deceleration visual inspection device in consideration of this inclination, or to perform correction using a table or the like.

When the mounting device 300 as described above is used, the acceleration / deceleration visual recognition device can be supported almost accurately in a horizontal state, and it is possible to eliminate an error in the reading value of the acceleration / deceleration visual recognition device.
