Embodiments for Carrying Out the Invention

[0009] A housing for storing ship-mounted electronic components generally has a vibration isolator mounted to mitigate vibrations and impacts inside the ship. Also, a vibration isolator protection jig is attached to the housing so that plastic deformation or damage does not occur to the vibration isolator due to vibrations or impacts applied to the housing or other supports during the transportation of the housing when installing the hull and before installing the hull. In the description of the embodiments and the drawings, the same elements and corresponding elements are denoted by the same reference numerals. Their names and functions are also the same or similar. The description of the elements denoted by the same reference numerals is omitted or simplified as appropriate. The expressions "upper" and "lower" refer to the direction or positional relationship determined by gravity unless the direction etc. is specified.

[0010] Embodiment 1. Hereinafter, this embodiment will be described in detail with reference to the drawings.

[0011] ***Description of the Configuration*** FIG. 1 is a front view showing an example of mounting the vibration isolator protection jig 100 according to Embodiment 1. FIG. 2 is a perspective view showing an example of mounting the vibration isolator protection jig 100. Figure 3 shows an example of the dashed line section shown in Figure 2.

[0012] The vibration-damping mount protective jig 100 is used together with the vibration-damping mount 200, the base 300, and the housing 400. The enclosure 400 houses 500 electronic components. The entire system, consisting of the vibration-damping mount protective jig 100, the vibration-damping mount 200, the base 300, and the housing 400 containing the electronic components 500, is also an electronic device installed on a ship.

[0013] As shown in Figures 1, 2, and 3, the vibration-damping mount protective jig 100 and the vibration-damping mount 200 are installed between the base 300 and the housing 400. The base 300 is positioned below both the vibration-damping mount 200 and the housing 400. As shown in Figure 2, multiple bases 300 may be attached to a single housing 400. Multiple sets of vibration-damping mount protective fixtures 100 and vibration-damping mounts 200 may be attached to a single base 300.

[0014] The configuration of the vibration-damping mount protective jig 100 will be explained using Figure 3. As shown in Figure 3, the vibration-damping mount protective jig 100 comprises an upper jig 10, a lower jig 20, and a bolt 30. A square nut (not shown) may be used with the bolt 30. At least a portion of each of the upper jig 10 and the lower jig 20 may be made of resin. In particular, the upper plate portion 11 may be made of resin.

[0015] Figure 4 is a perspective view showing an example of the upper jig 10. The upper jig 10 has an upper plate portion 11, a side plate portion 12, and an inclined portion 13.

[0016] The upper plate portion 11 has a plate-like shape. One end of the upper plate portion 11 in the longitudinal direction and one end of the side plate portion 12 in the longitudinal direction are connected such that the longitudinal direction of the upper plate portion 11 and the longitudinal direction of the side plate portion 12 intersect. The longitudinal direction of the upper plate portion 11 and the longitudinal direction of the side plate portion 12 may be perpendicular. At the connection portion between the upper plate portion 11 and the side plate portion 12, one side of the upper plate portion 11 and one side of the side plate portion 12 may be connected. In the installed state, the upper surface of the upper plate portion 11 is in contact with the lower surface of the housing 400.

[0017] The mounted state is one in which the vibration-damping mount protective jig 100 is attached to the vibration-damping mount 200 for the housing 400. The mounted state is achieved by rotating the threaded portion of the bolt 30, which passes through the elongated hole 14 and is inserted into the bolt hole 26 along the insertion direction of the bolt hole 26, in the direction of fastening of the threaded portion. In the mounted state, the upper plate portion 11 is located above the lower jig 20, and the side wall 320 is located between the side plate portion 12 and the lower jig 20. The method of protecting the vibration-damping mount 200 by attaching the vibration-damping mount protective jig 100 to the vibration-damping mount 200 constitutes a vibration-damping mount protection method.

[0018] The side plate portion 12 has a plate-like shape. The side plate portion 12 has an elongated hole 14. When installed, one side of the side plate portion 12 is in contact with the side wall 320 of the base 300 which is positioned below the housing 400. The length of the upper plate portion 11 in the shorter direction and the length of the side plate portion 12 in the shorter direction may be the same.

[0019] The elongated hole 14 is a hole surrounded by the planes of the side plate portion 12, and it penetrates from one of the two planes of the side plate portion 12 to the other. The shape of the elongated hole 14 is, for example, a rectangle and two semicircles or parts of a circle, like a running track. The threaded portion of the bolt 30 passes through the elongated hole 14. The longitudinal direction of the side plate portion 12 and the longitudinal direction of the elongated hole 14 are aligned. The length of the elongated hole 14 in the short direction is longer than the length of the threaded portion of the bolt 30 in the width direction, and shorter than the length of the head of the bolt 30 in the width direction. When the threaded portion of the bolt 30 passes through the elongated hole 14, the threaded portion is movable within the elongated hole 14 along the longitudinal direction of the elongated hole 14. When the threaded portion of the bolt 30 passes through the elongated hole 14 and is inserted into the bolt hole 26 along the insertion direction of the bolt hole 26, the head of the bolt 30 cannot pass through the elongated hole 14.

[0020] The inclined portion 13 is provided so as to connect to the upper plate portion 11 and the side plate portion 12 on the inside of the smaller of the corners formed by the upper plate portion 11 and the side plate portion 12. The inclined portion 13 is connected to the upper plate portion 11 in the longitudinal direction from one end of the upper plate portion 11 to the middle of the upper plate portion 11. The inclined portion 13 is connected to the side plate portion 12 in the longitudinal direction from one end of the side plate portion 12 to the middle of the side plate portion 12. The inclined portion 13 has a plane that fills a part of the space formed between the upper plate portion 11 and the side plate portion 12. The inclined portion 13 may be provided at one end of the upper plate portion 11 in the short direction and at the other end of the upper plate portion 11 in the same short direction. The inclined portion 13 is provided so as not to obstruct the movement of the threaded portion of the bolt 30 that passes through the elongated hole 14. The thickness of the inclined portion 13 may be set as appropriate. The inclined portion 13 has a hypotenuse that is inclined with respect to the longitudinal direction of the upper plate portion 11. A straight line along the hypotenuse intersects with a point in the upper plate portion 11 in its longitudinal direction, and also with a point in the side plate portion 12 in its longitudinal direction. In other words, a triangle may be formed by the direction along the hypotenuse of the inclined portion 13, the longitudinal direction of the upper plate portion 11, and the longitudinal direction of the side plate portion 12. The shape of the plane of the inclined portion 13 may be a triangle, a trapezoid, or another polygon. One end of the hypotenuse of the inclined portion 13 is connected to a point in the middle of the lower surface of the upper plate portion 11 in its longitudinal direction. The other end of the hypotenuse of the inclined portion 13 may be connected to a point in the middle of one of the planes of the side plate portion 12 in its longitudinal direction. The upper jig 10 may have two inclined portions 13. One of the inclined portions 13 of the upper jig 10 is connected to one end of the upper plate portion 11 in the short direction of the upper plate portion 11 and to one end of the side plate portion 12 in the short direction of the side plate portion 12. The other inclined portion 13 of the upper jig 10 is connected to the other end of the upper plate portion 11 in the short direction of the upper plate portion 11 and to the other end of the side plate portion 12 in the short direction of the side plate portion 12.

[0021] Figure 5 is a perspective view showing an example of the lower jig 20. Four inclined surfaces are formed on the side surface of the lower jig 20: a first inclined surface 21, a second inclined surface 22, a third inclined surface 23, and a fourth inclined surface 24. The term "inclined surface" is sometimes used as a general term for the multiple inclined surfaces formed on the side surface of the lower jig 20. Each inclined surface corresponds to the bottom surface of the groove formed on the symmetrical side surface of the prism. One inclined surface corresponds to one side surface of the lower jig 20. Any two inclined surfaces are formed on two non-adjacent sides of the prism. A contact surface 25 is formed between each pair of adjacent inclined surfaces. The prism is an octagonal prism as a specific example. In the mounted state, one of the inclined surfaces faces the hypotenuse of the inclined portion 13. The groove consists of two walls and a bottom surface. The groove has a notched shape. The two walls of the groove are formed at one end and the other end of the symmetrical surface of the prism in the height direction. One of the two walls corresponds to a part of the peripheral edge of the upper surface of the prism in the height direction. The other wall corresponds to a part of the peripheral edge of the lower surface of the prism in the height direction. The length between the two walls is wider than the width formed by the two inclined portions 13 of one upper plate portion 11 in the short direction of the upper plate portion 11. Therefore, when installed, the two inclined portions 13 of the upper jig 10 fit within the groove with respect to the height direction of the prism. Each bottom surface is a surface formed to conform to the side surface of the lower jig 20 corresponding to the groove portion corresponding to each bottom surface. When the two slanted edges of the two inclined portions 13 of one upper plate portion 11 are both facing each other with respect to any of the bottom surfaces, the two slanted edges can move along the inclined direction of the bottom surface. The direction of the slope of a given base is along the surface of that base and perpendicular to the height direction of the prism.

[0022] The first slope 21, the second slope 22, and the third slope 23 are each provided with bolt holes 26. The bolt holes 26 provided on each slope may span across each slope and the ground surface 25 adjacent to each slope. In addition, as shown in Figure 5, the bottom surface of the lower jig 20 may display the height when any of the ground surfaces 25 is grounded, which is the height from the grounded ground surface 25 to the starting position of the slope. In other words, when the lower jig 20 has multiple inclined surfaces, each of the multiple inclined surfaces is provided on each side of the rectangular prism, and the height from the ground surface 25 corresponding to each of the multiple inclined surfaces to the starting position of each of the multiple inclined surfaces is different from each other. Here, each of the multiple inclined surfaces is considered a target inclined surface, and when the threaded portion is inserted in the bolt hole of the target inclined surface along the insertion direction in the mounted state, the ground surface 25 corresponding to the target inclined surface is the surface of the lower jig 20 that is in contact with the upper surface of the bottom plate 310 of the base 300. In this case, the starting position of the inclined surface corresponding to the target inclined surface with respect to the ground surface 25 corresponding to the target inclined surface is the position of the target inclined surface that is closest to the ground surface 25 corresponding to the target inclined surface. In addition, between every two adjacent inclined surfaces of the multiple inclined surfaces, there is one or more sides of the rectangular prism that do not have any of the multiple inclined surfaces provided. The insertion direction of the bolt hole 26 is perpendicular to the height direction of the rectangular prism and is aligned with one of the contact surfaces 25 adjacent to the slope where the bolt hole 26 is provided. In the installed state, the threaded portion of the bolt 30 is inserted into the bolt hole 26 along the insertion direction that is aligned with the longitudinal direction of the upper plate portion 11. In the mounted state, one of the contact surfaces 25 is in contact with the upper surface of the bottom plate 310 of the base 300.

[0023] Figure 6 illustrates the differences in the starting positions of the slopes relative to each contact surface 25. In Figure 6, the bottom surface of the lower jig 20 is positioned parallel to the plane of the paper, and each slope and each bolt hole 26 located in the depth direction of the paper are shown by dashed lines.

[0024] As shown in Figure 6, the side surface of the lower jig 20 is formed such that a first inclined surface 21, a contact surface 25c, a second inclined surface 22, a contact surface 25a, a fourth inclined surface 24, a contact surface 25d, a third inclined surface 23, and a contact surface 25b are in contact in that order. The contact surface 25b and the first inclined surface 21 are in contact. Furthermore, the first slope 21 and the fourth slope 24, the second slope 22 and the third slope 23, the ground contact surfaces 25a and 25b, and the ground contact surfaces 25c and 25d are all arranged to face each other.

[0025] The bolt hole 26a is provided in the first inclined surface 21 such that the insertion direction of the bolt 30 is parallel to the ground surface 25a. The bolt hole 26b is provided in the second inclined surface 22 such that the insertion direction of the bolt 30 is parallel to the ground surface 25b. The bolt hole 26c is provided in the third inclined surface 23 such that the insertion direction of the bolt 30 is parallel to the ground surface 25c.

[0026] In the vibration-damping mount protective jig 100, as shown in Figure 3, when one of the contact surfaces 25 of the lower jig 20 is in contact with the bottom plate 310 of the base 300 (described later), the upper jig 10 is positioned on an inclined surface adjacent to the contact surface 25 that is opposite to the said contact surface 25, such that the insertion direction of the bolt 30 in the bolt hole 26 on the inclined surface is parallel to the contact surface 25 that is in contact with the base 300. Being in contact with the bottom plate 310 of the base 300 is sometimes synonymous with being in contact with the base 300.

[0027] Returning to Figure 6, Figure 6(a) shows the case where the contact surface 25a is in contact with the base 300. That is, in the state shown in Figure 6(a), the upper jig 10 is positioned on the first inclined surface 21. Figure 6(b) shows the case where the contact surface 25b is in contact with the base 300. That is, in the state shown in Figure 6(b), the upper jig 10 is positioned on the second inclined surface 22. Here, in Figure 6(b), the lower jig 20 is positioned rotated 180 degrees around the x-axis in Figure 6 from the state shown in Figure 6(a). Figure 6(c) shows the case where the contact surface 25c is in contact with the base 300. That is, in the state shown in Figure 6(c), the upper jig 10 is positioned on the third inclined surface 23.

[0028] With respect to the lower jig 20, as shown in Figure 6, the height from the contact surface 25 that is in contact with the bottom plate 310 of the base 300 to the starting position of the slope is different. The starting position of the slope is the part of the two slopes that are not in contact with the contact surface 25 that is in contact with the base 300 that is closest to the base 300. In Figure 6(a), the height from the contact surface 25a, which is in contact with the base 300, to the starting position of the first slope 21 is shown by the dashed line A. In Figure 6(b), the height from the contact surface 25b that is in contact with the base 300 to the starting position of the second slope 22 is shown by the dashed line B. In Figure 6(c), the height from the contact surface 25c, which is in contact with the base 300, to the starting position of the third slope 23 is shown by the dashed line C.

[0029] The height from the contact surface 25 in contact with the bottom plate 310 of the base 300 to the starting position of the slope shall be set according to other design requirements. For example, the height from the contact surface 25 in contact with the base 300 to the starting position of the slope may be set to the length of the free length of any vibration-damping mount 200.

[0030] Furthermore, in the lower jig 20, the inclination angle of the slope into which the bolt 30 is inserted parallel to the ground surface 25 is set to match the inclination angle of the hypotenuse of the inclined portion 13 of the upper jig 10 relative to the upper plate portion 11. As a result, when the upper jig 10 is placed on the slope, the hypotenuse of the inclined portion 13 of the upper jig 10 faces one of the slopes of the lower jig 20.

[0031] Figure 7 shows an example of the structure of the vibration-damping mount 200. The vibration-damping mount 200 has a ring 210 and a connecting portion 220. The base 300 has a bottom plate 310 and side walls 320.

[0032] The ring 210 is an elastic body that can expand and contract along the z-axis direction in Figure 7. The shape of the ring 210 is annular. The ring 210 has the function of absorbing vibrations of the housing 400.

[0033] The connecting portion 220 is a component that connects the ring 210 to other components. In Embodiment 1, two connecting portions 220 are provided for each ring 210. One of the connecting portions 220 is a member that connects the ring 210 to the housing 400. The other connecting portion 220 is a member that connects the ring 210 to the bottom plate 310 of the base 300.

[0034] The base plate 310 and the side wall 320 are formed integrally. The side walls 320 are inclined with respect to the base plate 310. In this specific example, there are two side walls 320.

[0035] The enclosure 400 houses multiple electronic components 500 inside. Connecting devices for mounting the enclosure 400 may be provided on the side or back of the enclosure 400.

[0036] ***Explanation of operation*** An example of operation when using the vibration-damping mount protective jig 100 will be explained with reference to Figures 1 and 2. Hereafter, with respect to the housing 400, the surface shown in Figure 1 will be referred to as the front, and the surface opposite the front will be referred to as the back.

[0037] First, the two bases 300 are placed with a gap between them in the x-direction in Figure 1, that is, in the width direction of the housing 400.

[0038] Next, vibration damping mounts 200 are placed on each base 300. In Embodiment 1, two vibration-damping mounts 200 are placed on a single base 300. The two vibration-damping mounts 200 are arranged side by side in the y-direction in Figure 1, i.e., in the depth direction of the housing 400, so that the compression direction of the ring 210 is aligned.

[0039] Next, the housing 400 is placed on the vibration-damping mount 200, and the vibration-damping mount 200 and the housing 400 are connected by the connection part 220.

[0040] Next, the upper jig 10 and lower jig 20 of the vibration-damping mount protective jig 100 are inserted between the base 300 and the housing 400. As shown in Figure 2, one vibration-damping mount protective jig 100 is used for one vibration-damping mount 200. With respect to the vibration-damping mount 200 positioned towards the front of the housing 400, the protective jig 100 for the vibration-damping mount is positioned towards the front of the housing 400 relative to the vibration-damping mount 200. With respect to the vibration-damping mount 200 positioned towards the rear of the housing 400, the protective jig 100 for the vibration-damping mount is positioned towards the rear of the housing 400 relative to the vibration-damping mount 200.

[0041] The two vibration-damping mounting fixtures 100, positioned towards the front and rear respectively, are both installed such that the bolts 30 are inserted into the housing 400 from the inside outwards. Furthermore, in each vibration-damping mount protective jig 100, as described above, the slanted edge of the inclined portion 13 of the upper jig 10 faces one of the inclined surfaces of the lower jig 20. In addition, the starting position of the inclined surface having bolt holes 26 parallel to the contact surface 25 that contacts the bottom plate 310 of the base 300 is aligned with the height of the contact surface 25. When the slanted edge of the inclined portion 13 of the upper jig 10 faces one of the inclined surfaces of the lower jig 20, the elongated hole 14 of the upper jig 10 faces the bolt hole 26 of the lower jig 20.

[0042] Next, the jack-up operation is performed using the vibration-damping mount protective jig 100. Figure 8 shows an example of the jack-up operation using the vibration-damping mount protective jig 100. Figure 8(a) shows the state of the protective jig 100 for the vibration-damping mount and the vibration-damping mount 200 before bolt tightening. In Figure 8(a), the ring 210 of the vibration-damping mount 200 is compressed in the compression direction due to the weight of the housing 400. Figure 8(b) shows the state of the vibration-damping mount protective jig 100 and vibration-damping mount 200 after bolt tightening.

[0043] First, the bolt 30 is inserted into the elongated hole 14 of the upper jig 10 and the bolt hole 26 of the lower jig 20. At this time, the bolt 30 is positioned above the elongated hole 14.

[0044] Next, the bolt 30 is tightened. As the bolt 30 rotates and is tightened, the upper jig 10 moves diagonally upward along the inclined portion 13. As a result, the upper plate portion 11, which is in contact with the bottom surface of the housing 400, pushes up the housing 400, that is, the vibration-damping mount protective jig 100 jacks up the housing 400. Also, as the bolt 30 rotates and is tightened, the side plate portion 12 of the upper jig 10 moves closer to the side wall 320 of the base 300. Subsequently, when the side plate portion 12 comes into contact with the side wall 320, the rotation of the bolt 30 is stopped. As a result, the height of the housing 400 is determined.

[0045] Figure 9 shows an example of a mounting configuration in which the height from the ground surface 25 to the starting position of the slope is different from that of the ground surface 25. Figure 9(a) shows the mounting state when the first inclined surface 21 faces the hypotenuse of the inclined portion 13. Figure 9(a) corresponds to the usage state of the lower jig 20 shown in Figure 6(a). Figure 9(b) shows the mounting state when the second inclined surface 22 faces the hypotenuse of the inclined portion 13. Figure 9(b) corresponds to the usage state of the lower jig 20 shown in Figure 6(b). Figure 9(c) shows the mounting state when the third inclined surface 23 faces the hypotenuse of the inclined portion 13. Figure 9(c) corresponds to the usage state of the lower jig 20 shown in Figure 6(c). As shown in Figure 9, if the identifiers of the inclined portion 13 and the inclined surface opposite each other are different, the heights of the upper plate portions 11 of each vibration-damping mount protective jig 100 relative to the base 300 will be different after jacking up.

[0046] When jacking up the housing 400, the jacking up by each vibration-damping mount protective jig 100 may be performed simultaneously, or the jacking up by one vibration-damping mount protective jig 100 may be performed sequentially, or the jacking up by two vibration-damping mount protective jig 100 located diagonally opposite each other with respect to the shape of the bottom surface of the housing 400 may be performed simultaneously and sequentially.

[0047] The housing 400 is transported with the heights of the upper plates 11 of each vibration-damping mount protective jig 100 aligned. During transport of the housing 400, the vibration-damping mounts 200 are protected from expansion and contraction due to the vibrations of the housing 400.

[0048] Once the transport of the housing 400 is complete, the vibration-damping mount protective fixtures 100 are removed. First, the connectors on the back or sides of the housing 400 are connected to the connectors at the installation site. Next, the bolts 30 of each vibration-damping mount protective fixture 100 are rotated to loosen them, and the upper fixture 10 and lower fixture 20 are removed.

[0049] When multiple housings 400 are arranged side by side in the width direction of the housings 400, the sides of each pair of housings 400 may be connected. Figure 10 shows an example of mounting the vibration-damping mount protective jig 100 when two housings 400 are connected. In this case, the height of the upper plate portion 11 of the vibration-damping mount protective jig 100 used during transport is aligned for each housing 400 by jacking it up, and the connecting parts of each housing 400 are held at the same height until the housings 400 are connected to each other.

[0050] ***Explanation of the effects of Embodiment 1*** In the vibration-damping mount protective jig 100, which includes an upper jig 10 and a lower jig 20, when the bolts 30 inserted into the elongated holes 14 and bolt holes 26 are tightened, the inclined portion 13 moves upward along the slope opposite to the inclined portion 13, jacking up the housing 400, and the height of the housing 400 is maintained when the side plate portion 12 is in contact with the side wall 320 of the base.

[0051] In other words, the height of the upper plate portion 11 relative to the base 300 in the mounted state is determined by the arrangement relationship between the side plate portion 12 and the inclined portion 13, and the height of the starting position of the inclined portion relative to the contact surface 25 that contacts the base 300. As a result, the vibration-damping mount protective jig 100 has the effect of being able to be mounted at a specified height without measuring the height. Furthermore, when multiple vibration-damping mount protective jigs 100 are properly attached to the bottom surface of the housing 400, there is no difference in height between each vibration-damping mount protective jig 100, and the bottom surface of the housing 400 can be kept parallel to the mounting surface of the housing 400.

[0052] This eliminates differences in mounting height between multiple vibration-damping mount protective fixtures 100, particularly when installing a housing 400 on a ship's hull or when connecting multiple housings 400 together. As a result, it prevents damage to connecting fixtures that are not at the correct height during housing 400 installation. Furthermore, it prevents damage to any vibration-damping mount 200 when the vibration-damping mount protective fixtures 100 are removed after housing 400 installation due to concentrated load.

[0053] Furthermore, in this embodiment, the upper jig 10 and the lower jig 20 are placed in a state where the slope and the inclined portion 13 are in contact before tightening the bolts 30. This eliminates the need to maintain the housing 400 at the height after bolt tightening using a crane or the like when jacking up the vibration-damping mount protective jig 100. Furthermore, according to this embodiment, it is no longer necessary to hold down the upper jig 10 and the lower jig 20 before tightening the bolts, thus reducing the burden during jacking up.

[0054] In addition, in the case of a vibration-damping mount protective jig 100 in which the lower jig 20 has multiple contact surfaces 25 and multiple slopes with different starting positions relative to any of the contact surfaces 25, the height of the upper jig 10 relative to the base 300 after jacking up can be changed by changing the contact surface 25 that contacts the bottom plate 310 of the base 300. This has the effect of allowing multiple heights of the housing 400 relative to the base 300 to be set with a single vibration-damping mount protective jig 100.

[0055] Furthermore, if the upper jig 10 is made of resin, it has the effect of preventing damage to the housing 400 when jacking up.
