  FIG. 1 is a front view showing a schematic shape of a board device according to a first embodiment of the present invention, FIG. 2 is a side view seen from the II-II line shown in FIG. 1, and FIG. It is the top view seen from the III-III line shown in FIG.

  Referring to these drawings, the wood board device 11 is obtained by engaging the wood main body 12 with the top of the wood base 13 and a support 37 attached to the top of the wood main body 12 is shown in FIG. It contacts the hull outer surface 7 indicated by the dotted line.

  The board base 13 is formed of a steel material, and a second curved plate 32 having a curved surface convex downward (corresponding to a cylindrical side wall surface) is disposed on the upper side in use, and below the second curved plate 32 Vertical plates 18a and 18b are connected to the curved surface so as to be perpendicular to the mounting surface. The lower ends of the vertical plates 18a and 18b are connected by welding or the like to the upper surface of the rectangular lower flat plate 53 arranged in parallel with the mounting surface, and the lower spacer 15 is installed on the lower surface of the lower flat plate 53. . On the upper surface of the second curved plate 32, a plurality of protrusions 35a to 35n having the same shape with a convex cross section are formed in parallel to the extending direction of the curved surface.

  The board main body 12 is formed of a steel material, and a height adjusting spacer 19 on which a support body 37 to be described later is installed is installed on the upper surface. A rectangular upper flat plate 20 is installed on the lower surface of the spacer 19. Vertical plates 17 a and 17 b are connected to the lower surface of the upper flat plate 20 by welding or the like in the vertical direction with the upper flat plate 20, and ends of the vertical plates 17 a and 17 b on the side facing the connection side with the upper flat plate 20. The portion is connected to the upper curved surface of the first curved plate 31 having a downwardly convex curved surface (corresponding to a cylindrical side wall surface). On the lower curved surface of the first curved plate 31, a plurality of protrusions 34a to 34n having the same shape and having a convex section are formed in parallel to the extending direction of the curved surface. The first curved plate 31 has a shape along the second curved plate 32.

  On the upper surface of the spacer 19 in the wood main body 12, a rectangular parallelepiped-shaped support body 37, the upper part of which is in contact with the hull outer surface 7, is disposed. Bolt holes 28a and 28b are formed in the support 37, and bolts 24a and 24b are inserted into the holes 37, respectively, and are closed by covers 27a and 27b made of an elastic material. The support body 37 is fastened to the upper flat plate 20 via the spacer 19 by the bolts 24 a and 24 b and the nuts 25 a and 25 b which are the respective pairs.

  The protrusions 35a to 35n in the second curved plate 32 have the same shape as the protrusions 34a to 34n in the first curved plate 31, and are arranged at substantially the same interval as their width. Further, one of the protrusions is set to a size that can be engaged between the other protrusions. For this reason, when it arrange | positions so that any two of the protrusions 34 may fit between adjacent protrusions 35, either of the protrusions 34 and either of the protrusions 35 may mesh | engage in the shape of a gear, The board main body 12 is locked on the board base 13.

  When this engagement state is simplified, any one convex protrusion of the protrusions 34a to 34n is engaged with one concave groove formed by any two adjacent protrusions 35a to 35n. By doing so, the board main body 12 is locked on the board base 13.

  The board device 11 shown in FIG. 1 has a fourth protrusion 34d from the left hand of the first curved plate between the protrusion 35a located at the leftmost end of the drawing and the adjacent protrusion 35b. It is mated. Similarly, each of the protrusions 35 and the protrusions 34 arranged on the right side has a relationship in which one of the protrusions 34 is fitted between two adjacent protrusions 35.

  At this time, the support 37 has a certain inclination from the upper left to the lower right in FIG. In order to make the inclination moderate, it is only necessary to shift the engagement so that the protrusion 34 fitted between the adjacent protrusions 35 becomes the protrusion 34 positioned on the left side of the state shown in the figure. If the degree is steep, it may be shifted in the opposite direction to the gentler case.

  That is, when the combination of the protrusions 34a to 34n and the protrusions 35a to 35n is changed, the inclination of the support body 37 in the board main body 12 changes at regular intervals.

  Thus, since the inclination of the support 37 can be freely adjusted within a certain range, it can be easily adjusted to a desired inclination according to the shape of the place of contact with the support 37 of the ship to be used. At the same time, it is possible to maintain the state, and a user-friendly board device is realized. In addition, the inclination of the support 37 is uniquely determined by the engagement relationship between the protrusions 34a to 34n and the protrusions 35a to 35n, and the reliability of the board device 11 is improved.

  FIG. 4 is an enlarged cross-sectional view taken along line IV-IV shown in FIG. 3 and shows the configuration of the support 37.

  Referring to the figure, a support 37 has a plurality of constraining materials 40a to 40n such as woven fabric and non-woven fabric made of fiber or resin, etc., embedded in an elastic material 39 such as rubber or synthetic resin as an elastic material. An iron plate 55 is embedded in the portion of the support 37 that is closest to the contact surface with the spacer 19. As described above, the support body 37 is formed with the bolt holes 28, and the bolts 24 for fastening with the board main body 12 are inserted into the bolt holes 28, and the bolts are formed thereon by the cover 27 made of an elastic material. By closing the hole 28, the upper surface of the portion where the bolt hole 28 is formed also becomes an elastic surface. Further, since the bolt 24 does not contact the ship, damage to the ship due to the bolt 24 is also prevented. When the load of the ship is applied, the support body 37 is deformed so as to be recessed downward along the shape of the contact surface of the ship. However, the restraining materials 40a to 40n and the iron plate 55 serve as a reinforcing material and are more durable. A highly functional board device is realized.

  FIG. 5 is a front view showing a schematic shape of a board device according to a second embodiment of the present invention, FIG. 6 is a side view seen from the VI-VI line shown in FIG. 5, and FIG. It is the top view seen from the VII-VII line shown in FIG.

  With reference to these drawings, the description of the same parts as those of the board apparatus according to the first embodiment will not be repeated, and only the differences will be described.

  First, the board device 11 is provided with two supports 37a and 37b having a relatively short width compared to the width of the board body 12 in the tilt direction. These are attached to the board main body 12 through the spacers 21a and 21b for adjusting the inclination so as to have a certain degree of inclination. For example, the support body 37a is fastened to the upper flat plate 20 by means of bolts 24a and 24b inserted into the bolt holes 28a and 28b, and nuts 25a and 25b that are paired with the spacers 21a and the height adjusting spacer 19, respectively. Has been. At this time, since the support 37a is inclined by the spacer 21a, the support 37a is not parallel to the upper flat plate 20. For this reason, taper washers 26a and 26b are arranged between the nuts 25a and 25b and the lower surface of the upper flat plate 20, and are tightened after adjusting the angle. Similarly, with respect to the support 37b, angle adjustment at the time of fastening by the bolts 24c and 24d and the nuts 25c and 25d is performed by the taper washers 26c and 26d. In this embodiment, the height adjusting spacer 19 is not always necessary and may not be provided.

  In the board apparatus 11 in this embodiment, the inclination of the contact surface of each of the supports 37a and 37b with the outer surface 7 of the hull varies according to the shape of each of the spacers 21a and 21b. For this reason, since it is possible to adjust the inclination of each of the support bodies 37a and 37b in addition to the adjustment of the inclination of the entire board main body 12, a more appropriate contact state can be obtained as compared with the board apparatus in the previous embodiment. It can be easily secured.

  Next, a method for engaging the wood main body 12 and the wood base 13 will be described.

  The point that the protrusions 34a to 34n in the first curved plate 31 of the block main body 12 and the protrusions 35a to 35n in the second curved plate 32 of the block base 13 are meshed with each other is the same as in the previous embodiment. It is. In this embodiment, as shown in FIG. 6, the first curved plate 31 and the second curved plate 32 have a wider width in the direction perpendicular to the inclination direction.

  In the first curved plate 31, openings 42 a to 42 n and openings 49 a to 49 n are formed in the outer side end portions where the protrusions 34 a to 34 n are not formed.

All of these openings have the same circular shape. Moreover, when any of the openings 42a to 42n in the first curved plate 31 and any of the openings 43a to 43n in the second curved plate 32 is in the engagement state of the wood main body 12 and the wood base 13 is in any position. Are also formed in a positional relationship penetrating on one linear axis. The positional relationship between the openings 49a to 49n in the first curved plate 31 and the openings 50a to 50n in the second curved plate 32 is the same.

  In the woodcut device 11 shown in the figure, the pin 47a is inserted into the first curved plate 31 through the third opening 42c from the left hand with respect to FIG. 5 and the leftmost opening 43a of the second curved plate 32. Is detachably attached. Similarly, the pin 47b is detachably attached in such a manner that the rightmost opening 42n of the first curved plate 31 and the third opening 43h counted from the right hand of the second curved plate are inserted. Similarly, the pins 48a and 48b are detachably attached to the openings 49a to 49n in the first curved plate 31 and the openings 50a to 50n in the second curved plate 32 on the opposite side. The pins 47a and 47b are connected to the board main body 12 via chains 44a and 44b attached to the vertical plate 17a and attached to the locking member 46a, respectively. Similarly, the pins 48a and 48b are connected to the board main body 12 via chains 45a and 45b attached to a locking tool 46b attached to the vertical plate 17b.

  Thus, by attaching the pins 47a and 47b and the pins 48a and 48b, relative movement between the wood main body 12 and the wood base 13 is prevented. For this reason, compared with the previous embodiment, the engagement state of the board main body 12 and the board base 13 is more stable, and the reliability of maintaining the contact state of the supports 37a and 37b with the hull outer surface 7 is maintained.
