  The present invention relates to a vibrometer.

  Conventionally, a strong seismometer that measures the vibration of a structure during an earthquake has been used (for example, see Patent Document 1). This strong motion meter is attached to the installation surface of the structure (for example, the floor surface of the structure), performs vibration measurement during an earthquake, and records the measurement result.

(Details of vibration meter body and mounting base-Configuration of vibration meter body and mounting base)
First, regarding the configuration of the vibrometer main body 10, specifically, as shown in FIGS. 4A to 4C, the housing 20 of the vibrometer main body 10 has a first through hole 25a to a first through hole. A hole 25d and a second through-hole 26a to a second through-hole 26d are provided (in addition, the first through-hole 25a to the first through-hole 25d are referred to as “first when it is not necessary to distinguish them from each other”. The second through hole 26a to the second through hole 26d are collectively referred to as the “second through hole 26” when it is not necessary to distinguish them from each other.

  The first through hole 25a to the first through hole 25d are in a direction substantially perpendicular to both side surfaces between the upper surface and the lower surface of the housing 20 (that is, between the upper surface of the cover portion 22 and the lower surface of the base portion 21). It is a through-hole penetrating along (corresponding to the Z direction shown in FIG. 1). Each of the first through hole 25a to the first through hole 25d is disposed at each of the four corners of the housing 20 as viewed from the upper surface side or the lower surface side. Further, the size of the hole diameter of the first through hole 25 is arbitrary, but is set to be approximately the same as the outer diameter of the mounting pin 50 (about the hole diameter of the second through hole 26 described later). The same shall apply).

  The second through hole 26a to the second through hole 26d are provided between the front surface and the back surface of the housing 20 (that is, in the case of the second through holes 26a and 26b, between the front surface and the back surface of the base portion 21, In the case of the through-holes 26c and 26d, the through-holes pass through the cover portion 22 from the front side to the back side along a direction (corresponding to the Y direction shown in FIG. 1) substantially perpendicular to both side surfaces. Each of the second through hole 26 a to the second through hole 26 d is disposed at each of the four corners of the housing 20 as viewed from the front side or the back side.

  As for the configuration of the mounting base 60, specifically, as shown in FIG. 3, fixing portions 63a to 63d are provided on the side surface of the mounting base 60 on the vibration meter body 10 side (note that The fixing parts 63a to 63d are collectively referred to as “fixing part 63” when it is not necessary to distinguish between them.

  The fixing part 63a to the fixing part 63d are fixing means for fixing the attachment pin 50 inserted through the first through hole 25 or the second through hole 26. These fixing portions 63 a to 63 d are arranged in a portion of the side surface on the vibration meter main body 10 side of the mounting base 60 that faces the first through hole 25 or the second through hole 26. Here, with respect to the fixing of the mounting pin 50 to the fixing portion 63, for example, an end portion on the mounting base 60 side of the mounting pin 50 that is threaded is provided in the fixing portion 63. The mounting pin 50 is fixed to the fixing portion 63 by being inserted into the screw hole 64 (specifically, the screw hole 64 having a screw groove formed on the inner peripheral surface of the screw hole 64) and tightened.

  With such a configuration, the attachment pin 50 is inserted into each of the first through hole 25a to the first through hole 25d and fixed to the fixing portion 63, whereby the vibrometer on the upper surface or the lower surface of the housing 20 and the attachment base 60 is obtained. The side surface on the main body 10 side can be fixed, or the mounting pin 50 is inserted into each of the second through-hole 26a to the second through-hole 26d and fixed to the fixing portion 63. The vibration meter main body 10 side surface of the mounting base 60 can be fixed. That is, the upper surface, the lower surface, or the rear surface of the housing 20 can be selectively fixed to the common side surface of the mounting base 60 on the vibrometer body 10 side. Accordingly, the vibration meter body 10 can be attached to the installation surface W in various directions via the attachment base 60 without changing the installation angle of the vibration meter body 10 with respect to the X direction, the Y direction, or the Z direction. .

  In particular, since the housing 20 is formed in a regular hexahedron shape, for example, when the lower surface of the housing 20 and the mounting base 60 are fixed (hereinafter referred to as a first fixed state), the upper surface of the housing 20 is attached to the mounting surface. When the base 60 is fixed (hereinafter referred to as a second fixed state), the area of the contact portion of the mounting base 60 with the vibrometer body 10 can be made substantially the same. Thereby, for example, when the area of the contact portion in the first fixed state is different from that in the second fixed state (for example, when the area of the contact portion in the first fixed state is smaller than the second fixed state), It can be avoided. Specifically, when the mounting base 60 is formed based on the area of the contact portion in the first fixed state, the area of the contact portion with the mounting base 60 of the vibrometer body 10 in the second fixed state is the first. By being smaller than the fixed state, it is possible to avoid the vibration meter main body 10 from being difficult to be stably fixed to the mounting base 60. Further, when the mounting base 60 is formed based on the area of the contact portion in the second fixed state, the contact area of the mounting base 60 with the vibrometer body 10 in the first fixed state is smaller than that in the second fixed state. By becoming, it can avoid that a useless part arises in the attachment base 60 at the time of a 1st fixed state. Moreover, since the housing | casing 20 is fixed to the common side surface by the side of the vibrometer main body 10 in the attachment base 60, the attachment base 60 can be formed with a simple structure.

  In addition, the first through hole 25a to the first through hole 25d penetrating along the direction substantially orthogonal to the upper surface and the lower surface of the housing 20, or the first through hole penetrating along the direction substantially orthogonal to the front and back surfaces of the housing 20. Since the mounting pin 50 is inserted through the second through hole 26a to the second through hole 26d, for example, when the installation surface W is substantially along the X direction, the Y direction, or the Z direction, the vibrometer body 10 is When the vibration meter main body 10 is attached to the installation surface W via the attachment base 60, the side surface on the installation surface W side and the side surface opposite to the side surface are substantially along the installation surface W, and the vibration meter main body 10 has the installation surface W. The vibration meter main body 10 can be guided by the mounting pin 50 so that the side surface substantially orthogonal to the side surface is substantially orthogonal to the installation surface W. Thereby, it is a part of vibrometer main body 10, Comprising: The edge part by the side of the installation surface W in each of 1st through-hole 25a-1st through-hole 25d (or each of 2nd through-hole 26a-2nd through-hole 26d) Since the mounting pin 50 can be brought into contact with the entire region corresponding to the region extending from the end to the end opposite to the end, the vibrometer main body 10 maintains a state along the horizontal direction or the vertical direction. As a result, the centering of the vibration meter main body 10 with respect to the installation surface W can be accurately performed.

  The lower surface of the housing 20 corresponds to the “first side surface” in the claims, the upper surface of the housing 20 corresponds to the “second side surface” in the claims, and the rear surface of the housing 20 The front surface of the housing 20 corresponds to the “fourth side surface” in the claims.

(Details of vibration meter body and mounting base-shape of vibration meter body and mounting base)
Next, regarding the shapes of the vibration meter main body 10 and the mounting base 60, for example, the upper surface, the lower surface, or the back surface of the housing 20 and the side surface of the mounting base 60 on the vibration meter main body 10 side can be fitted to each other. It may be formed in a shape. Specifically, as shown in FIGS. 3 and 4A to 4C, four corners of the upper surface of the housing 20 are formed to be substantially concave than portions other than the four corners. (The same applies to the shape of the lower surface and the rear surface of the housing 20). Further, the fixing portion 63a to the fixing portion 63d provided on the side surface of the mounting base 60 on the vibrometer body 10 side are portions of the side surface facing the vibration meter main body 10 (however, the fixing portion 63a to the fixing portion 63d are excluded). ) (More specifically, a portion facing the vibration meter main body 10 is formed in a through-hole shape).

  With such a shape, the upper surface of the housing 20 (or the lower surface or the back surface of the housing 20) can be fitted to the side surface of the mounting base 60 on the vibrometer body 10 side. The alignment with respect to 60 can be easily performed.

(Details of the vibration meter body and mounting base-other configurations related to the vibration meter body)
Next, as for other configurations related to the vibration meter main body 10, for example, the side surface on the display unit 30 a to display unit 30 c side in the housing 20 and the side surface on the connection portions 40 a and 40 b side in the housing 20 are attached to the mounting base 60. It is preferable that the display unit 30a to the display unit 30c and the connection units 40a and 40b are arranged so as not to contact each other and to face each other. Specifically, as shown in FIGS. 2A to 2D, as described above, when the upper surface, the lower surface, or the rear surface of the housing 20 is fixed to the mounting base 60, the display units 30a to 30a. The display unit 30 c is disposed at the left side position in the housing 20, and the connection units 40 a and 40 b are disposed at the right side position in the housing 20. In this case, with regard to the arrangement of the light guide portion 23a to the light guide portion 23c and the connection ports 24a and 24b, for example, the light guide portion 23a to the light guide portion 23c are disposed on the left surface of the housing 20, and the connection ports 24a and 24b. Is arranged on the right surface of the housing 20.

  With such an arrangement, even when the upper surface, the lower surface, or the rear surface of the housing 20 is fixed to the side surface of the mounting base 60 on the vibration meter main body 10 side, the left surface of the housing 20 (that is, the display unit in the housing 20). 30a to the display unit 30c side) and the vibrometer main body so that the right side of the housing 20 (that is, the side surface of the housing 20 on the connection portions 40a and 40b side) is difficult to touch. 10 can be attached to the installation surface W via the attachment base 60.

(Details of vibrometer body and mounting base-other configurations related to mounting base)
Next, as for the other configuration related to the mounting base 60, for example, a configuration that can accurately mount the vibrometer body 10 substantially along the X direction, the Y direction, or the Z direction is preferable. Specifically, as shown in FIGS. 3, 5 (a) and 5 (b), an inclination adjusting portion 65 is provided at each of the four corners of the mounting base 60 as viewed from the side surface on the vibrometer body 10 side. It has been. The tilt adjusting unit 65 is tilt adjusting means for adjusting the tilt of the vibration meter main body 10 or the mounting base 60 with respect to the installation surface W. The inclination adjusting unit 65 is configured using, for example, a known bolt material. In addition, the inclination adjusting unit 65 is attached to the mounting base 60 so that the end of the inclination adjusting unit 65 on the installation surface W side (specifically, the tip of the shank portion of the inclination adjusting unit 65) contacts the installation surface W. Through screw holes 66a to 66d (specifically, through screw holes 66a to 66d having thread grooves formed on the inner peripheral surfaces of the through screw holes 66a to 66d). 66d).

  Here, with respect to the length of the inclination adjusting unit 65 in the Z direction, for example, the length of the inclination adjusting unit 65 in the Z direction is set longer than the length of the mounting base 60 in the Z direction. Accordingly, for example, as shown in FIG. 5B, when the installation surface W is inclined with respect to the X direction, the end of the inclination adjustment unit 65 on the installation surface side due to the tightening degree of the inclination adjustment unit 65. By projecting the portion to the mounting base 60, a gap can be generated between the mounting base 60 and the installation surface W. Such adjustment of the gap by the inclination adjusting portion 65 is performed independently for each of the inclination adjusting portions 65 through which the through screw holes 66a to 66d are inserted (specifically, on the low inclination side). (By adjusting the gap by the tilt adjusting unit 65 so that the tightening amount of the tilt adjusting unit 65 is larger than the tilt adjusting unit 65 on the higher tilt side), the mounting base 60 is substantially along the X direction. Further, the attachment base 60 can be attached to the installation surface W. In addition, since a gap is generated between the end of the inclination adjusting portion 65 opposite to the installation surface W side (specifically, the head portion of the inclination adjusting portion 65) and the mounting base 60, the inclination adjustment portion 65 is inclined by vibration or the like. The adjustment part 65 becomes easy to loosen. Therefore, in order to prevent such a slack of the inclination adjusting unit 65, for example, a spring material 67 (for example, a coil spring) that urges the head portion of the inclination adjusting unit 65 toward the side opposite to the installation surface W side. May be provided between the above.

  With such a configuration, the inclination of the vibration meter main body 10 with respect to the installation surface W can be adjusted, and the vibration meter main body 10 can be accurately attached substantially along the X direction, the Y direction, or the Z direction.

(installation method)
Next, a method for attaching the vibrometer 1 configured as described above will be described. FIG. 6 is a left side view showing the vibrometer 1 attached to the installation surface W in a floor-mounted state to be described later. FIG. 7 is a left side view showing the vibrometer 1 attached to the installation surface W in a ceiling-mounted state to be described later. FIG. 8 is a left side view showing the vibrometer 1 attached to the installation surface W in a wall-mounted state to be described later. Here, as shown in FIG. 6, the vibration meter 1 is attached in such a manner that the vibration meter body 10 is an installation surface W that is an installation surface W substantially along the X direction and the Y direction and is a floor surface of an office building. And the “floor mounting state” mounting method in which the vibration meter main body 10 has an installation surface W substantially along the X direction and the Y direction as shown in FIG. And a mounting method in a “ceiling-mounted state” that is attached in contact with the installation surface W, which is the ceiling surface of the office building, via the attachment base 60, and as shown in FIG. The installation method is divided into three types, that is, a substantially wall-mounted installation surface W and a “wall-mounted state” attachment method in which the installation surface W is attached to the installation surface W that is the wall surface of the office building via the attachment base 60. The floor-mounted state corresponds to the “first mounting state” in the claims, the ceiling-mounted state corresponds to the “second mounting state” in the claims, and the wall-mounted state corresponds to the claims. This corresponds to the “third attachment state”.

(Mounting method-floor placement)
First, the installation method in the floor-mounted state will be described. As shown in FIG. 6, first, the vibration meter main body 10 is fitted to the mounting base 60 so that the lower surface of the housing 20 of the vibration meter main body 10 and the side surface of the mounting base 60 on the vibration meter main body 10 side are in contact. .

  Next, the mounting pin 50 is inserted into each of the first through hole 25 a to the first through hole 25 d provided in the housing 20 and fixed to the fixing portion 63, whereby the lower surface of the housing 20 and the mounting base 60 are fixed. The vibration meter main body 10 side is fixed.

  Subsequently, the side of the mounting base 60 opposite to the vibrometer body 10 side is brought into contact with the installation surface W. While maintaining this state, the installation bolt 62 is driven on the installation surface W through each of the through holes 61 a to 61 d provided in the attachment base 60, and the penetrations provided in the attachment base 60 are provided. The attachment base 60 is attached to the installation surface W by inserting and tightening the inclination adjusting portion 65 into each of the screw holes 66a to 66d. More specifically, the front and back surfaces of the housing 20 are substantially orthogonal to the X direction, the left and right surfaces of the housing 20 are substantially orthogonal to the Y direction, and the upper and lower surfaces of the housing 20 are approximately the Y direction. The attachment base 60 is attached to the installation surface W so as to be orthogonal to each other.

  Here, regarding the placement of the installation bolt 62 onto the installation surface W, for example, as shown in FIG. 5A, when the installation surface W is substantially along the X direction, the installation of the inclination adjusting unit 65 is performed. After the inclination adjusting unit 65 is tightened until the end on the surface W side comes into contact with the installation surface W, the installation bolt 62 is driven until the head portion of the installation bolt 62 comes into contact with the mounting base 60. In this case, the entire side surface of the mounting base 60 opposite to the vibrometer body 10 is in contact with the installation surface W. In addition, as shown in FIG. 5B, when the installation surface W is inclined with respect to the X direction, the end of the inclination adjusting unit 65 on the installation surface W side is in contact with the installation surface W and vibrates. After tightening the inclination adjusting portion 65 until the meter body 10 is substantially along the X direction, the installation bolt 62 is driven until the head portion of the installation bolt 62 comes into contact with the mounting base 60. In this case, only a part of the side surface of the mounting base 60 opposite to the vibrometer body 10 side is in contact with the installation surface W (Note that this step includes a ceiling-mounted mounting method, and The same applies to the mounting method in the wall-mounted state, and will be omitted in the following description).

  Thus, in the mounting method in the floor-mounted state, the measurement direction of the first vibration sensor mounted on the circuit board of the vibrometer body 10 is substantially along the X direction, and the measurement direction of the second vibration sensor is substantially along the Y direction. And the vibrometer main body 10 can be attached to the installation surface W via the attachment base 60 so that the measurement direction of the third vibration sensor is substantially along the Z direction.

(Mounting method-ceiling mounted state)
Next, a method for mounting the ceiling-mounted state will be described. As shown in FIG. 7, first, the vibration meter main body 10 is fitted to the mounting base 60 so that the upper surface of the housing 20 of the vibration meter main body 10 and the side surface of the mounting base 60 on the vibration meter main body 10 side are in contact. .

  Next, the mounting pin 50 is inserted into each of the first through hole 25 a to the first through hole 25 d provided in the housing 20 and fixed to the fixing portion 63, so that the upper surface of the housing 20 and the mounting base 60 are fixed. The vibration meter main body 10 side is fixed.

  Thus, in the mounting method in the ceiling-mounted state, the vibration meter main body 10 can be mounted on the installation surface W via the mounting base 60 without changing the installation angle of the vibration meter main body 10 in the floor-mounted mounting method. .

(Mounting method-wall hanging)
Finally, a mounting method in the wall hanging state will be described. As shown in FIG. 8, first, the vibration meter main body 10 is fitted to the mounting base 60 so that the back surface of the housing 20 of the vibration meter main body 10 and the side surface of the mounting base 60 on the vibration meter main body 10 side come into contact. .

  Next, the mounting pin 50 is inserted into each of the second through hole 26 a to the second through hole 26 d provided in the housing 20 and fixed to the fixing portion 63, whereby the rear surface of the housing 20 and the mounting base 60 are The vibration meter main body 10 side is fixed.

  As described above, in the wall-mounted mounting method, the vibration meter main body 10 is attached via the mounting base 60 without changing the installation angle of the vibration meter main body 10 in the floor-mounted mounting method (or the ceiling-mounted mounting method). Can be attached.

(effect)
Thus, according to the present embodiment, by changing the mounting position of the vibration meter body 10 with respect to the mounting base 60 without changing the installation angle with respect to the X direction, the Y direction, or the Z direction, Since at least two or more mounting states can be taken among the floor-mounted state, the ceiling-mounted state, and the wall-mounted state, the single vibrometer 1 can be mounted on the installation surface W in various directions. As a result, there is no need to manufacture a product according to each mounting state, so the number of parts and the efficiency of manufacturing work can be reduced and the manufacturing cost can be reduced as compared with the conventional vibration meter. it can. In addition, because it is not necessary to perform inventory management and delivery management for each product according to each mounting state, it is possible to improve the efficiency of management work compared to conventional vibrometers and simplify inventory management and delivery management. Can be done.

  Further, since the vibration meter main body 10 is formed in a substantially regular hexahedron shape, for example, the area of the contact portion of the mounting base 60 with the vibration meter main body 10 in the floor-mounted state and the ceiling-mounted state (or wall-mounted state) is reduced. It can be made substantially the same. Thereby, for example, when the area of the contact portion in the floor-mounted state is different from the ceiling-mounted state (for example, when the area of the contact portion in the floor-mounted state is smaller than the ceiling-mounted state), it is possible to avoid the adverse effects that occur. it can. Specifically, when the mounting base 60 is formed based on the area of the contact portion in the floor-mounted state, the area of the contact portion with the mounting base 60 of the vibration meter main body 10 in the ceiling-mounted state is larger than the floor-mounted state. As a result, the vibration meter main body 10 can be prevented from being difficult to be stably fixed to the mounting base 60. Further, when the mounting base 60 is formed based on the area of the contact portion in the ceiling-mounted state, the contact area of the mounting base 60 with the vibration meter main body 10 in the floor-mounted state is smaller than that in the ceiling-mounted state. In addition, it is possible to avoid a useless portion from being generated on the mounting base 60 when the floor is placed. Further, the vibration is performed so that the upper surface, the lower surface, or the rear surface of the vibration meter main body 10 can be selectively fixed to the common side surface on the vibration meter main body 10 side of the mounting base 60 according to the mounting state of the vibration meter main body 10. Since the meter body 10 and the mounting base 60 are formed, the mounting base 60 can be formed with a simple structure, and the productivity of the mounting base 60 can be improved.

  In addition, the first through hole 25a to the first through hole 25d penetrating along the direction substantially orthogonal to the upper surface and the lower surface of the housing 20, or the first through hole penetrating along the direction substantially orthogonal to the front and back surfaces of the housing 20. Since the mounting pin 50 is inserted through the second through hole 26a to the second through hole 26d, for example, when the installation surface W is substantially along the X direction, the Y direction, or the Z direction, the vibrometer body 10 is When the vibration meter main body 10 is attached to the installation surface W via the attachment base 60, the side surface on the installation surface W side and the side surface opposite to the side surface are substantially along the installation surface W, and the vibration meter main body 10 has the installation surface W. The vibration meter main body 10 can be guided by the mounting pin 50 so that the side surface substantially orthogonal to the side surface is substantially orthogonal to the installation surface W. Thereby, it is a part of vibrometer main body 10, Comprising: The edge part by the side of the installation surface W in each of 1st through-hole 25a-1st through-hole 25d (or each of 2nd through-hole 26a-2nd through-hole 26d) Since the mounting pin 50 can be brought into contact with the entire region corresponding to the region extending from the end to the end opposite to the end, the vibrometer main body 10 maintains a state along the horizontal direction or the vertical direction. As a result, since the centering with respect to the installation surface W of the vibrometer main body 10 can be accurately performed, the measurement accuracy of the vibrometer 1 can be improved.

  Further, since the upper surface, the lower surface, or the rear surface of the housing 20 and the side surface of the mounting base 60 on the vibrometer body 10 side are formed in a shape that can be fitted to each other, the upper surface (or the housing) of the housing 20 is formed. The lower surface or the back surface of the body 20 can be fitted to the side surface of the mounting base 60 on the vibration meter main body 10 side, and the vibration meter main body 10 can be easily aligned with the mounting base 60. In addition, a fixing portion 63a to a fixing portion 63d are provided in a portion of the mounting base 60 facing the first through hole 25a to the first through hole 25d or the second through hole 26a to the second through hole 26d, and the fixing portion 63a to the fixing base 63 are fixed. Since the mounting pin 50 is fixed to each of the parts 63d via any one of the first through hole 25a to the first through hole 25d or the second through hole 26a to the second through hole 26d, The lower surface or the rear surface can be selectively fixed to a common side surface of the mounting base 60 on the vibration meter body 10 side, and can be in three mounting states: a floor-mounted state, a ceiling-mounted state, and a wall-mounted state. It becomes possible.

  Further, the side surfaces on the display unit 30a to display unit 30c side in the vibrometer main body 10 and the side surfaces on the connection portions 40a and 40b side in the vibrometer main body 10 do not contact the installation surface W and the mounting base 60, and Since the display unit 30a to the display unit 30c and the connection units 40a and 40b are arranged so as to face each other, for example, the side surface on the display unit 30a to the display unit 30c side of the housing 20 is easy to touch the human eye, and the housing The vibration meter main body 10 can be attached to the installation surface W via the attachment base 60 so that the side surfaces of the connection portions 40a and 40b in FIG. Is possible.

  Moreover, since the inclination adjusting part 65 for adjusting the inclination with respect to the installation surface W in the vibration meter main body 10 is provided in the mounting base 60, the inclination with respect to the installation surface W in the vibration meter main body 10 can be adjusted. It becomes possible to attach the main body 10 so as to be substantially along the X direction, the Y direction, or the Z direction.

Specifically, screw holes (specifically, screw holes having screw grooves on the inner peripheral surface of the screw holes) are formed at positions corresponding to the fixing portions 63 on the upper surface, the lower surface, and the rear surface of the housing 20. At the same time, a through hole is formed in each fixing portion 63 of the mounting base 60. Then, after the vibration meter main body 10 is fitted to the mounting base 60, a known fixing screw is inserted into the screw hole through the through hole from the side of the mounting base 60 opposite to the vibration meter main body 10 and tightened. Accordingly, the vibration meter main body 10 and the mounting base 60 may be fixed. In this case, the shape of the through hole is preferably such that the head portion of the fixing screw can be accommodated inside the through hole so that the head portion of the fixing screw does not protrude outward from the mounting base 60.
