Description

TECHNICAL FIELD The present invention relates to a measuring tool and a measuring stand used for measuring the distance of a gap in the body of a vehicle.

In order to prevent wind and rain from entering the interior of the vehicle, or to reduce noise, etc., the opening and closing parts of the vehicle where the back door, side door, etc. A sealing member (weather strip rubber) is attached. In addition, the gap (between the seal surfaces) between the seal surface on the main body side and the seal surface of the mating member such as the door must be provided with an appropriate clearance in order to ensure the sealing performance of the weatherstrip rubber.

In order to appropriately set the distance between the seal surfaces (the distance between the seal surfaces), the distance between the seal surfaces is measured at a plurality of locations along the circumference of the opening/closing portion. The distance between the sealing surfaces must be measured when the mating member such as a door is closed with respect to the main body. In addition, since the weatherstrip rubber is attached so as to surround the periphery of the opening of the main body, it is necessary to measure the distance between seal surfaces at many positions around the periphery of the opening.

The gap between the sealing surfaces is the distance between the two members and is also the internal gap between the main body and the door, so it cannot be directly seen from the outside when the door is closed. Further, for example, the distance between the sealing surfaces of the main body and the back door is about 20 to 30 mm, and it is extremely difficult to directly measure the distance using a laser measuring device, vernier caliper, or the like. Furthermore, the distance between the seal surfaces may have an error in the actual size value with respect to the designed distance due to various factors such as the reaction force of the back door support member and the load of the door. On the other hand, the distance between the sealing surfaces is required to be measured with high precision in order to ensure the sealing performance of the weatherstrip rubber.

Conventionally, when measuring the actual size value of the distance between the seal faces, it was mainly done using a material that is plastically deformable (hereinafter sometimes referred to as "clay etc.") such as clay and silicon. . Specifically, first, clay or the like is kneaded to an appropriate size and prepared. Next, clay or the like is molded into a long and narrow shape and attached to the opening periphery of the main body, after which the doors and the like are opened and closed. Then, take out the plastically deformed clay or the like (plastically deformed material) sandwiched between the main body and the mating member, and use the plastically deformed material as a substitute for the seal surface using a measuring instrument such as a vernier caliper. do. In one measurement operation, clay or the like is attached to about four locations around the opening and deformed, and the predetermined positions of the plastically deformed object are measured. In one measurement operation, measurements are performed at about 50 locations around the opening. By repeating such work, the separation distance between the seal surfaces is measured.

As a technique for measuring the distance between seal surfaces, Patent Document 1 below discloses a seal surface dimension measuring device having a body-side target board, a door-side target board, a laser beam irradiation unit, a stereo camera, and an image processing unit. It is The overall device for measuring the inter-seal surface dimension of Patent Document 1 uses the target marks on the body and door side target boards to reproduce the cross-sectional shape of the body and door side seal surfaces in the same state as when the door is closed. It is said that the dimension between the sealing surfaces can be measured accurately and in a short time because it can be positioned as accurately as possible.

JP 2013-50363 A

However, the sealing surface dimension measuring device of Patent Document 1 merely reproduces the same state as when the door is closed by image processing for the cross-sectional shape on the body side and the cross-sectional shape on the door side. Therefore, the actual distance between the body and the door (dimension between the sealing surfaces) cannot eliminate errors from the actual dimensions. Furthermore, the seal-to-seal dimension measuring device of Patent Document 1 requires a large number of devices, resulting in a high cost.

In addition, the conventional method for measuring the seal face distance using clay or the like has problems such as the number of man-hours required for measurement and unstable measurement accuracy. Specifically, in the conventional method for measuring the distance between the sealing surfaces, there is a problem that the number of man-hours increases due to the work for preparing the clay, such as kneading and molding the clay for each measurement work. In addition, the back door is pushed away from the body by the reaction force of clay, etc., and errors occur in the measured values. It is necessary to repeat the measurement work. Therefore, there is a problem that the number of measurement man-hours increases further.

In addition, in the conventional method of measuring the distance between the seal faces, plastically deformed clay or the like was used as a substitute for the seal face and measured using a vernier caliper. There is a problem that variations occur depending on the person who measures, and the part to be measured cannot be measured accurately and stably.

Furthermore, after the clay or the like is attached to the opening periphery of the body body, the door is temporarily moved from the locked position toward the body body side by pressing (overstroke) at the time of locking when the door is closed. Therefore, there is a problem that the clay or the like is crushed and the distance between the sealing surfaces does not match, resulting in an error, and being affected by overstroke.

Furthermore, the measured values are not stable due to various factors such as familiarity, feeling, tricks, how to close the door, measurement angle, and the amount of force applied during measurement. There is a problem that it is necessary to repeat the measurement work in consideration of such variations in the measured values, and the number of man-hours for the measurement increases more and more.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a measuring tool and a measuring stand that reduce the number of man-hours in the measuring work and contribute to improving the measuring accuracy when measuring the clearance of the body gap such as between seal surfaces.

A measuring tool according to the present invention, which is provided to solve the above-described problems, is a measuring tool for measuring the distance between a body main body and a lid-like member forming an opening/closing part of a vehicle, wherein the gap between the body main body and the lid-like member is When one of them is a structure A and the other is a structure B, the body main body can and a displacement pin capable of making a stroke so that the stroke amount changes according to the distance of the gap; a regulating member that regulates the stroke of the displacement pin in the closed state in which the lid-like member is closed with respect to the body; It has a regulation operation part for operating a regulation member, and a connection part that connects the regulation member and the regulation operation part, and the connection part is composed of a wire part that is set to be deformable.

Therefore, according to the measuring tool of the present invention, the influence of overstroke and the like can be eliminated, and the distance between the main body and the lid member can be measured with high accuracy.

Further, according to the measuring tool of the present invention, the length of the entire measuring tool can be measured as the distance between the seal surfaces. In other words, with the measuring tool of the present invention, the portion to be measured is naturally limited. Therefore, according to the measuring instrument of the present invention, it is possible to avoid variations in the position of the object to be measured depending on the operator, and to measure the part to be measured accurately and stably. Furthermore, when measuring the distance between the main body and the lid-like member using the measuring tool of the present invention, the length of the entire measuring tool can be obtained accurately. As a result, measurement accuracy can be improved by eliminating variations in measurement performed by different people, compared to the case of performing measurement work using vernier calipers or the like.

Moreover, the measuring tool of the present invention can reduce the influence of reaction force compared to clay or the like. Therefore, the measuring tool of the present invention can attach many measuring tools and measure many points in one measuring operation. As a result, the measuring tool of the present invention can reduce man-hours required for the measuring work.

A measuring tool 10 and a measuring table 60 according to an embodiment of the present invention will be described below with reference to the drawings.

The measuring tool 10 is used to measure the distance between the gaps of the body 2 forming the outer shape of the vehicle 1 . As shown in FIG. 1, a vehicle 1 has an outer shape formed by a plurality of bodies 2 including a main body 4, a back door 6 (lid-shaped member), a side door 7 (lid-shaped member), and the like. Further, as shown in FIGS. 1 and 2, the vehicle 1 has an opening/closing portion 3 in which a back door 6 is attached to the opening 4a of the body 4 so that the back door 6 can be opened and closed. A flange 4c is formed at the edge 4b of the opening 4a of the main body 4. As shown in FIG.

As shown in FIG. 3, when the back door 6 is closed, the flange 4 c is provided with a seal member for blocking the gap between the main body 4 and the back door 6 to prevent the entry of wind and rain or suppress noise. A weatherstrip rubber 8 is attached. In the following description of the present embodiment, a case where the measuring tool 10 is used to measure the distance between the body 4 and the back door 6 will be described.

The measuring tool 10 is used to measure the distance between the main body 4 forming the opening/closing portion 3 of the vehicle 1 and the back door 6 . As described above, the weatherstrip rubber 8 is attached to the main body 4 side of the opening/closing portion 3 . Moreover, the weather strip rubber 8 is attached so as to close the gap between the body main body 4 and the back door 6 that is formed when the back door 6 is closed. The measuring tool 10 is used to measure the distance between the sealing surface F1 on the main body 4 side and the sealing surface F2 on the back door 6 side.

In the following description, the space between the sealing surface F1 on the side of the main body 4 and the sealing surface F2 on the side of the back door 6 may be referred to as "between the sealing surfaces S". Further, the distance between the sealing surface F1 of the body main body 4 and the sealing surface F2 of the back door 6 may be described as "a distance D1 between the sealing surfaces".

The distance D1 between the sealing surfaces varies depending on the type of the vehicle 1 and the like, but is a gap of about 20 to 30 mm. Moreover, since the gap S between the sealing surfaces is an internal gap of the body 2, it cannot be directly visually recognized from the outside. Therefore, it is extremely difficult to directly measure the distance D1 between the seal surfaces using a measuring instrument such as a vernier caliper. On the other hand, in order to properly attach the weatherstrip rubber 8, it is necessary to appropriately set the distance D1 between the sealing surfaces over the entire peripheral portion of the opening 4a. The measuring tool 10 forms a distance D2 that coincides with the seal face distance D1 and is used as a measuring surrogate for measuring the seal face distance D1. Each configuration of the measuring tool 10 will be described below.

As shown in FIGS. 4 and 5, the measuring tool 10 has a base portion 20, a stroke pin 40 (displacement pin), a spring 48 (biasing member), and a wire screw 50. As shown in FIGS. The measuring instrument 10 has a structure in which a spring 48 is housed in the base portion 20 and the stroke pin 40 is attached to the base portion 20 while being biased by the spring 48 .

As shown in FIG. 8, the measuring tool 10 attaches the base portion 20 to the main body 4 (construction A), and brings the stroke pin 40 into contact with the back door 6 (construction B) to obtain the distance between the sealing surfaces. A distance D2 that coincides with D1 can be formed.

As shown in FIG. 4 , the base portion 20 has a main body portion 22 and a magnet member 38 , and is detachable from the body 2 such as the main body 4 by the magnetic force of the magnet member 38 . The magnet member 38 is formed with a base end surface 20a that forms the bottom surface of the base portion 20 and contacts the main body 4 (construction A). The magnet member 38 has a substantially U-shape and is provided so as to close the bottom surface 22 a of the main body 22 .

In the description of the measuring tool 10 below, the direction substantially perpendicularly crossing the base end surface 20a may be described as the "stroke direction X". In some cases, the side of the base end surface 20a in the stroke direction X is simply referred to as the "base end side", and the side opposite to the base end side is simply referred to as the "distal end side".

As shown in FIG. 5, the body portion 22 is formed with a fitting portion 28 which is formed in a deep concave shape from the base end side to the tip end side. Further, the main body portion 22 is provided with a screw mounting portion 24 having a female screw groove. A thumbscrew 26 (locking tool) is attached to the screw attachment portion 24 . The flange 4c is fitted into the fitting portion 28, and the base portion 20 is positioned with respect to the main body 4 by attaching the thumbscrew 26 to the screw fitting portion 24 and bringing it into contact with the flange 4c.

As shown in FIG. 5, the body portion 22 is formed with a stroke hole 30 penetrating along the stroke direction X from the bottom surface 22a to the upper surface 22b. A stepped portion 32 is formed in the middle of the stroke direction X in the stroke hole 30 . A region inside the stroke hole 30 is divided into a first region 34a on the proximal end side and a second region 34b on the distal end side with the stepped portion 32 as a boundary. The wall surface of the second region 34b is formed so as to be in surface contact with the peripheral surface of the stroke pin 40. As shown in FIG. In other words, the wall surface of the second region 34b is formed so as to maintain the posture of the stroke pin 40 along the stroke direction X while allowing the stroke pin 40 to be displaced. A spring 48 is accommodated in the first region 34a. In addition, the stroke pin 40 is arranged in the second region 34b with the tip portion 44 taken out of the main body portion 22. As shown in FIG. The first region 34 a is closed by attaching the magnet member 38 to the main body 22 .

As shown in FIG. 6, a screw hole 36 is formed in the side surface 22d of the body portion 22. As shown in FIG. A female screw groove is formed on the inner peripheral surface of the screw hole 36 . The screw hole 36 is formed to reach the stroke hole 30 from the side surface 22d. Moreover, the screw hole 36 is formed so as to extend in a direction intersecting with the stroke direction X. As shown in FIG. A screw hole 36 is also formed in a side surface 22e of the body portion 22 opposite to the side surface 22d. A screw portion 52 of a wire screw 50 to be described later is attached to the screw hole 36 .

As shown in FIG. 5 , the stroke pin 40 (displacement pin) is a pin member attached to the base portion 20 . The stroke pin 40 has a proximal end portion 42 arranged on the proximal end side in the longitudinal direction and a distal end portion 44 arranged on the distal end side. Further, the stroke pin 40 has a flange portion 46 formed like a flange. The base end portion 42 and the flange portion 46 are housed in the first region 34a. Further, the tip side of the stroke pin 40 is arranged in the second region 34b. The movement of the stroke pin 40 toward the distal end side is restricted at the position where the flange portion 46 and the stepped portion 32 contact each other. Thereby, the measuring tool 10 prevents the stroke pin 40 from falling off from the base portion 20 .

A spring 48 is attached to the base end portion 42 of the stroke pin 40 to bias the stroke pin 40 toward the distal end side. Further, the stroke pin 40 can be retracted toward the base end surface 20a against the biasing force of the spring 48. As shown in FIG. In other words, the stroke pin 40 can be stroked along the stroke direction X. Further, as described above, the outer peripheral surface of the stroke pin 40 is in surface contact with the wall surface of the second region 34b. Therefore, the stroke pin 40 can be displaced in the stroke direction X while maintaining a posture along the stroke direction X. As shown in FIG. In other words, the displacement pin 40 makes a stroke against the biasing force of the spring 48 by coming into contact with the back door 6, and can change the stroke amount, which is the amount of displacement in the stroke direction X with respect to the base portion 20. It is

The spring 48 (biasing member) is a spring member provided to bias the stroke pin 40 in a direction away from the base end surface 20a. The spring 48 is housed in the first region 34a while being attached to the base end portion 42 of the stroke pin 40. As shown in FIG.

In the operation of measuring the distance D1 between seal surfaces, an error may occur in the distance D1 between seal surfaces depending on the spring constant of the spring 48 and the number of measuring tools 10 attached. Specifically, when the spring constant of the spring 48 is large or when a large number of measuring tools 10 are used, the back door 6 is pushed away from the main body 4 by the reaction force of the spring 48, and the seal surface Distance D1 may increase. Therefore, the spring 48 is desirably selected so as to have little influence of the reaction force, considering the load displacing the back door 6, the allowable error, the number of the measuring tools 10, and the like.

For example, assuming that the allowable range of error in the measurement value due to the reaction force of the biasing member is 0.1 mm, the spring 48 is the load required to displace the back door 6 of the vehicle to be measured by 0.1 mm. , and the number of measuring tools 10 to be used at the same time, it is desirable to select a spring constant within a predetermined range.

A wire screw 50 is provided to restrict and allow displacement of the stroke pin 40 . The wire screw 50 is provided as a single wire member. At both ends of the wire screw 50, a screw portion 52 (regulating member) having a thread groove is formed at one end, and a rotating portion 54 (regulating operation portion) capable of performing a rotating operation is provided at the other end. . In the wire screw 50, the threaded portion 52 and the rotating portion 54 are connected via a wire portion 56 (connecting portion). In other words, the wire screw 50 is provided so as to separate the threaded portion 52 and the rotating portion 54 . A tube 58 that covers the wire portion 56 is attached to the wire screw 50 .

The threaded portion 52 (regulating member) is attached to the threaded hole 36 of the base portion 20 . The threaded portion 52 restricts the displacement of the stroke pin 40 and enables the stroke pin 40 to be positioned in the stroke direction X by pressing the threaded tip portion 52 a against the stroke pin 40 . Further, the threaded portion 52 allows displacement of the stroke pin 40 by separating the threaded tip portion 52 a from the stroke pin 40 .

The rotating portion 54 (restriction operation portion) is provided to perform a displacement restriction operation for restricting displacement of the stroke pin 40 by the screw portion 52 . More specifically, when the rotating portion 54 is rotated in the positive direction, torque is applied to the threaded portion 52 via the wire portion 56 to move the threaded portion 52 from the threaded hole 36 to the inside of the body portion 22 . The threaded tip portion 52a is brought into contact with the stroke pin 40 by advancing. As a result, the stroke pin 40 is pressed against the threaded portion 52 and its displacement in the stroke direction X is restricted. When the rotating portion 54 is rotated in the opposite direction, the threaded portion 52 is retracted to the outside of the body portion 22 to separate the threaded tip portion 52 a from the stroke pin 40 . As a result, the stroke pin 40 is released from the pressure of the threaded portion 52 and allowed to move in the stroke direction X. As shown in FIG. By rotating the rotating portion 54 in a predetermined direction, the displacement of the stroke pin 40 is restricted (displacement restricted state) and the displacement of the stroke pin 40 is permitted (displacement permitted state). can be switched. In other words, the measuring tool 10 can perform a displacement restricting operation for restricting the displacement of the stroke pin 40 by rotating the rotating portion 54 (regulating operation portion).

The wire portion 56 (connecting portion) is provided to separate the rotating portion 54 from the threaded portion 52 and transmit the torque generated by the rotating operation to the rotating portion 54 to the threaded portion 52 .

Next, a specific example of the measuring table of the present invention will be described. FIG. 7 is a perspective view showing a state in which the measuring tool 10 is set on the measuring table 60 according to the embodiment of the present invention. The measuring table 60 is used for measuring the distance D2 from the base end surface 20a of the measuring tool 10 to the tip portion 44 in a series of operations for measuring the inter-seal surface distance D1.

The measurement table 60 has a stacking table 62 , a measuring device attachment portion 64 , a positioning portion 66 and two wire support portions 68 . The measuring table 60 is attached to a plate-like stacking table 62 having a flat surface so that a measuring device attachment portion 64 is erected. It should be noted that the measuring table 60 can set two measuring tools 10 thereon.

The positioning portion 66 has a first member 66a having a substantially dogleg shape in plan view, and a second member 66b and a third member 66c having substantially rectangular shapes. The measuring tool 10 is arranged so that the tip portion 44 is directly below the measurement starting point C of the laser measuring device T by setting it in contact with the second member 66b and the third member 66c. In other words, the positioning portion 66 functions as a guide portion for setting the measuring tool 10 to the measurable position.

A wire support 68 is provided to support the wire screw 50 of the measuring tool 10 . A concave portion 68 a is formed in the wire support portion 68 . The wire support portion 68 supports the wire portion 56 with the concave portion 68 a and functions as a member for preventing displacement of the measuring tool 10 due to the load of the wire portion 56 and moss.

The measuring device attachment portion 64 is provided to enable attachment of a distance measuring device such as a laser measuring device T (not shown in FIG. 7). When the laser measuring device T is attached to the measuring device attachment portion 64 , the irradiation portion (measurement starting point C) of the laser measuring device T is arranged directly above the tip portion 44 of the measuring tool 10 .

Next, a series of operations for measuring the distance D1 between seal surfaces will be described with reference to FIG. When measuring the distance D1 between seal surfaces, first, the measuring tool 10 is attached to the main body 4 side with the back door 6 opened. More specifically, a plurality of (for example, about 4 to 10) measuring tools 10 are attached to the flange 4c of the main body 4. As shown in FIG. In addition, it is desirable that the measurement tool 10 is arranged so that the measured values are not biased, taking into consideration the reaction force of the spring 48 . For example, it is desirable that the measuring tools 10 be arranged on the left and right sides of the vehicle 1 in the same number (for example, four on the right side and four on the left side) with respect to the edge 4b of the opening 4a. As a result, it is possible to prevent the influence of the reaction force of the spring 48 from deviating to either the left or the right side and reducing the measurement accuracy.

When the measurement tool 10 is attached to the main body 4 , the measurement tool 10 is in a state in which the screw tip 52 a is separated from the stroke pin 40 . That is, the measuring tool 10 is attached to the main body 4 in a state in which the stroke pin 40 is allowed to be displaced in the stroke direction X (displacement allowed state).

As shown in FIG. 8, the measuring tool 10 is attached to the main body 4 by the magnetic force of the magnet member 38. As shown in FIG. The measuring instrument 10 is fixed to the main body 4 by fitting the flange 4c into the fitting portion 28 and bringing the tip of the butterfly screw 26 into contact with the flange 4c. In this manner, the measuring instrument 10 is attached so that the base end surface 20a formed on the magnet member 38 is substantially in surface contact with the main body 4, and the engagement between the flange 4c, the fitting portion 28, and the thumbscrew 26 is achieved. It is positioned in place by the structure.

After attaching the measuring tool 10 to the main body 4, the back door 6 is closed. As shown in FIG. 8, when the back door 6 is locked, the back door 6 temporarily moves toward the main body 4 within a range from the lock position P1 to the displaceable position P2 (see the phantom line in FIG. 8). It moves (over stroke) and returns to the locking position P1 when the back door 6 is locked. At this time, the tip portion 44 of the stroke pin 40 is temporarily displaced toward the base end surface 20a as the back door 6 moves. Further, when the back door 6 returns to the lock position P1, the stroke pin 40 is displaced toward the front end side by the biasing force of the spring 48 to a position where the front end portion 44 and the back door 6 come into contact with each other.

In this way, regardless of the magnitude of the influence of overstroke, the measuring instrument 10 is configured such that the distance D2 between the base end surface 20a and the tip portion 44 is the distance D1 between the seal surfaces when the back door 6 is maintained at the lock position P1. can be matched with As a result, the measuring tool 10 can reduce the error caused by the influence of the overstroke in the work of measuring the distance D1 between the seal surfaces.

When the back door 6 is closed, the rotating portion 54 (restriction operating portion) of the wire screw 50 is pulled out from between the body main body 4 and the back door 6 . When the rotating portion 54 of the wire screw 50 is rotated, the screw portion 52 (restricting member) enters the screw hole 36, and the screw tip portion 52a eventually comes into contact with the outer peripheral surface of the stroke pin 40 and presses it. When the threaded tip portion 52a presses the outer peripheral surface of the stroke pin 40, the displacement of the stroke pin 40 in the stroke direction X is restricted and positioned in the stroke direction X (displacement restriction state).

After positioning the stroke pin 40 in the stroke direction X, the back door 6 is opened and the measuring tool 10 is removed from the main body 4 . In the measuring tool 10 removed from the main body 4, the distance D2 from the base end surface 20a to the tip end portion 44 is kept in agreement with the inter-seal surface distance D1.

Next, the distance D2 from the proximal end surface 20a of the measuring instrument 10 to the distal end portion 44 is measured. Specifically, as shown in FIG. 9, the measuring tool 10 is set on the measuring table 60, and the distance D2 from the proximal end surface 20a to the distal end portion 44 is measured. In addition, it is desirable to measure the distance D3 from the irradiation portion (measurement starting point C) of the laser measuring device T to the stacking table 62 in advance. The measuring tool 10 is set on the measuring table 60, and the distance D4 from the measurement starting point C to the tip 44 of the measuring tool 10 is measured by the laser measuring device T. FIG. A value obtained by subtracting the distance D4 from the distance D3 is calculated as the distance D2 from the proximal end surface 20a of the measuring tool 10 to the distal end portion 44. FIG.

The measured value of the distance D2 obtained by the above procedure agrees with the measured value of the distance D1 between the sealing surfaces where the measuring tool 10 is arranged. In this way, in the operation of measuring the distance D1 between the seal surfaces using the measuring tool 10 and the measuring table 60, the measured value of the distance D1 between the seal surfaces can be obtained accurately and efficiently.

In the series of measuring operations for the distance D1 between the seal surfaces, the measuring operation is performed by attaching the measuring tool 10 to the main body 4 in the state where the weatherstrip rubber 8 is not attached in the first measuring operation, and the second measuring operation is performed. The measuring work may be performed by attaching the measuring tool 10 while the weather strip rubber 8 is attached in the work. In addition, as shown in FIG. 10, in the work of measuring the distance D1 between the sealing surfaces, a part of the weatherstrip rubber 8 is cut and intermittently arranged, and the measuring tool is placed between the weatherstrip rubbers 8 and 8. 10 may be attached for measurement work. This makes it possible to measure the distance D1 between the seal surfaces in a state closer to that of the actual vehicle.

Although the embodiments of the measuring tool and measuring table of the present invention have been described above, the measuring tool and measuring table of the present invention are not limited to the above-described embodiments.

For example, in the above-described embodiment, the measuring tool 10 is used for measuring the distance S between the sealing surfaces of the body main body 4 and the back door 6, but the measuring tool 10 of the present invention is It may be used to measure other gaps in the body 2 such as the distance S between the sealing surfaces of the side door 7 and the side door 7 .

In the measuring tool 10 described above, an example is shown in which the screw member (screw portion 52) is used as the configuration for regulating the displacement of the stroke pin 40. The displacement of the stroke pin may be regulated.
