For example, the shape of the float 2, the shape of the first support member 31, the shape of the second support member 32, and the like in FIG. 1 are merely schematically represented for the sake of explanation and are shown. It is not limited to the shape.

(Embodiment 1)
[1] Overview First, an overview of the hull-mounting float device (also simply referred to as “float device”) 1 according to the present embodiment will be described with reference to FIG.

The float device 1 is a device (equipment) used by being attached to the hull B1 of a canoe or a kayak. That is, the float device 1 is not originally provided integrally with the hull B1, but is a device that is retrofitted to the hull B1. Since a wide variety of canoes or kayaks are generally distributed, the size and shape of the hull B1 to which this type of float device 1 is attached also varies. Considering the attachment to such a wide variety of hulls B1, the configuration in which the height of the float 2 (see FIG. 1) is only adjusted stepwisely and roughly as in the above-mentioned related technique is not possible. It is difficult to adjust the float 2 to the optimum height. On the other hand, the float device 1 according to the present embodiment has the following configuration, which makes it easy to adjust the float 2 to the optimum height even when it is attached to a wide variety of canoes or kayaks.

That is, as shown in FIG. 1, the float device 1 according to the present embodiment includes a float 2, a first support member 31, a second support member 32, and a coupling structure 4. The first support member 31 is attached to the float 2. The second support member 32 is attached to the hull B1 of the canoe or kayak. The coupling structure 4 couples the first support member 31 and the second support member 32. The coupling structure 4 has a guide mechanism 41 and a lock mechanism 42. The guide mechanism 41 guides the movement of the first support member 31 with respect to the second support member 32 within a predetermined range R1 (see FIG. 4A) along the height direction D1 to provide a second support in the height direction D1. The position of the float 2 with respect to the member 32 is variable. The lock mechanism 42 fixes the relative position of the first support member 31 with respect to the second support member 32 at an arbitrary position within the predetermined range R1.

According to this configuration, the float device 1 makes it possible to adjust the relative height of the float 2 with respect to the hull B1 (that is, the relative position in the height direction D1) by the coupling structure 4. Here, the coupling structure 4 guides the movement of the first support member 31 with respect to the second support member 32 within the predetermined range R1 along the height direction D1 by the guide mechanism 41. That is, the first support member 31 can move relative to the second support member 32 in the height direction D1 as long as it is within the predetermined range R1. Then, the coupling structure 4 fixes the relative position of the first support member 31 with respect to the second support member 32 at an arbitrary position within the predetermined range R1 by the lock mechanism 42. In short, the locking mechanism 42 sets the first support member 31 and the second support at an "arbitrary" position within a predetermined range R1 where the guide mechanism 41 allows the relative movement of the first support member 31 with respect to the second support member 32. Positioning with the member 32 is performed. Therefore, the relative position of the first support member 31 with respect to the second support member 32 can be finely adjusted, and the position of the float 2 with respect to the second support member 32 (hull B1) in the height direction D1 can be finely adjusted. As described above, since the position of the float 2 in the height direction D1 can be finely adjusted, it is easy to adjust the float 2 to the optimum height even when it is attached to a wide variety of canoes or kayaks.

Here, in a canoe or kayak, in general, the size is smaller, the bottom is shallower, and the total length is shorter than other ships such as boats. Degree becomes more important. For example, if the float 2 sinks too deeply with respect to the water surface (that is, the position of the float 2 is too low), the stability of the hull B1 becomes high, but the resistance of water received by the float 2 becomes too large. Therefore, it hinders the propulsive force of the hull B1. On the contrary, if the sinking condition of the float 2 with respect to the water surface is too shallow (that is, the position of the float 2 is too high), the hull B1 becomes less stable, although the hull 2 suppresses the obstruction of the propulsive force of the hull B1. It gets lower. Further, the hull B1 of a canoe or a kayak has various forms of the bottom of the hull, and the buoyancy generated in the hull B1 varies. Therefore, in order to achieve both the stability and the propulsive force of the hull B1, the float 2 It is required to optimally adjust the degree of contact between the surface and the water surface for each hull B1. Therefore, it is particularly useful for a canoe or a kayak that the position of the float 2 in the height direction D1 can be finely adjusted and the float 2 can be easily adjusted to the optimum height as in the present embodiment. be.

That is, when the float device 1 is attached to the hull B1, the float 2 projects (projects) in the left-right direction D2 from at least one of the port side (left side surface) and the starboard side (right side surface) of the hull B1. It is arranged so as to improve the stability of the posture of the hull B1 on the water.

As used herein, "canoe or kayak" means a small vessel including a Canadian canoe or various kayaks. In particular, "kayaks" include various types of kayaks such as sit-on-top kayaks, folding kayaks, sea kayaks and river kayaks. In the present embodiment, as an example, a case where the float device 1 is used (attached) to a kayak (fishing kayak) used for kayak fishing will be described, but the float or kayak in which the float device 1 is used will be described. It is not intended to limit the types.

The "position of the float 2 with respect to the second support member 32" referred to in the present disclosure is the so-called "height of the float 2" and corresponds to the height of the float 2 from the water surface. In the present embodiment, the "position of the float 2 with respect to the second support member 32" is represented by the distance H1 (see FIG. 1) between the second support member 32 and the float 2 in the height direction D1. More specifically, the distance H1 between the center of the second support member 32 in the height direction D1 and the center of the first support member in the height direction D1 is set to "the position of the float 2 with respect to the second support member 32". Is defined.

The term "parallel" as used in the present disclosure means, in addition to the case where two straight lines on one plane do not intersect with each other no matter how long they are extended, that is, the angle between the two is exactly 0 degrees (or 180 degrees). , It means that the angle between the two is within an error range of about several degrees (for example, less than 10 degrees) with respect to 0 degrees. Similarly, the term "orthogonal" as used in the present disclosure means that the angle between the two parties intersects exactly at 90 degrees, and the angle between the two parties is about several degrees (for example, less than 10 degrees) with respect to 90 degrees. It means that the relationship is within the error range of.

In the present embodiment, as an example, the outer peripheral shape of the cross section orthogonal to the longitudinal direction of the horizontal bar portion 321 (see FIG. 2) described later is a square shape (rectangular shape).

[3] Details Next, the details of the float device 1 according to the present embodiment will be described with reference to FIGS. 1 to 6. In this embodiment, as described above, the hull B1 is a kayak used for kayak fishing. Here, in particular, it is assumed that the float device 1 is attached to the hull B1 of the sit-on type kayak. In FIG. 1 and the like, a part of the hull B1 is shown by an imaginary line (dashed-dotted line).

The float device 1 according to the present embodiment is directly attached to the hull B1 by using mounting screws (including bolts) (including bolts) (not shown). That is, the float device 1 can be removed from the hull B1 by removing the mounting screws. In this way, the float device 1 is retrofitted to the hull B1 in a state of being removable from the hull B1. In the present embodiment, with the float device 1 attached to the hull B1, the float 2 is on the port side of the hull B1, that is, the left hand side when the occupant (user) of the hull B1 looks at the bow (that is, the front). It is arranged so as to project (project) to the left (to the right in FIG. 1) along the left-right direction D2 from the left side surface of the hull B1.

As shown in FIGS. 1 and 2, the float device 1 includes a float 2, a first support member 31, a second support member 32, and a coupling structure 4. Further, the float device 1 is, for example, a float device such as a screw (including a bolt), a washer, a nut, etc. that connects a second support member 32 and a guide mechanism 41 (a tubular member 51 described later). Further, a fastener for connecting the components of 1 is provided. However, these fasteners are merely one means for fastening the components to each other, and can be replaced by means such as welding, integral molding, or adhesion. Therefore, in FIG. Illustration of these fasteners is omitted as appropriate.

Further, in the present embodiment, the material of most of the parts except the float 2 and the tightening screw 53 in the float device 1 is metal. However, due to the nature of being used on the surface of the water, the parts of the float device 1 naturally include metal parts such as SUS (or plated metal parts) that take into consideration performance such as waterproofing and rust prevention. Used. On top of that, the materials, thickness, and the like of the parts of the float device 1 are set so as to maintain sufficient strength required for each.

The float 2 is a part that generates buoyancy with respect to water, and is, for example, a part made of a resin such as polyethylene. The shape of the float 2 itself can be changed as appropriate, but is formed, for example, into a shape having a length along the traveling direction of the hull B1, that is, the front-rear direction D3.

The first support member 31 is a component attached to the float 2. As shown in FIG. 2, the first support member 31 has an insertion portion 311, a cover plate 312, a screw 313, and a fastener 314. The insertion portion 311 is made of a metal tubular member (hollow pipe). The insertion portion 311 has a length in a direction orthogonal to the height direction D1 (here, the left-right direction D2). In the present embodiment, the insertion portion 311 is a cylindrical round pipe, and the outer peripheral shape of the cross section orthogonal to the longitudinal direction (here, the left-right direction D2) of the insertion portion 311 is circular (round shape). The insertion portion 311 is integrated with the rod-shaped member 52 of the guide mechanism 41 described later, and the insertion portion 311 and the rod-shaped member 52 as a whole are formed in an L shape. Here, of the L-shaped round pipe, the short side portion along the left-right direction D2 is the insertion portion 311 and the long side portion along the height direction D1 is the rod-shaped member 52.

The insertion portion 311 is inserted into the opening hole 21 penetrating the float 2 in the left-right direction D2. The cover plate 312 is made of metal, for example, and is attached to the float 2 so as to cover the periphery of the opening hole 21 of the float 2 from above. The screw 313 is fastened to the screw hole 315 formed in the insertion portion 311 through the cover plate 312 to prevent the first support member 31 from rotating with respect to the float 2. The fastener 314 is made of, for example, a metal band or the like, and is fixed so as to tighten the cover plate 312 and the insertion portion 311 in a state where the cover plate 312 and the insertion portion 311 are inserted. As a result, the first support member 31 is fixed to the float 2 with the insertion portion 311 inserted into the opening hole 21 of the float 2.

The second support member 32 is a component mounted on the hull B1. As shown in FIG. 2, the second support member 32 has a horizontal bar portion 321, a joint metal fitting 322, a screw with a knob 323, and a stay 324. The horizontal bar portion 321 is made of a metal tubular member (hollow pipe). The horizontal bar portion 321 has a length in a direction orthogonal to the height direction D1 (here, the left-right direction D2). The outer peripheral shape of the cross section orthogonal to the longitudinal direction (here, the left-right direction D2) of the horizontal bar portion 321 is non-circular. As described above, since the outer peripheral shape of the cross section of the horizontal bar portion 321 is non-circular, the rotation of the horizontal bar portion 321 with respect to the hull B1 is suppressed, and the inclination of the float 2 with respect to the hull B1 is easily suppressed. In the present embodiment, as an example, the horizontal bar portion 321 is a square tubular pipe, and the outer peripheral shape of the cross section orthogonal to the longitudinal direction of the horizontal bar portion 321 is a quadrangular shape (rectangular shape).

The horizontal bar portion 321 is fixed to the hull B1 by the joint metal fitting 322 and the screw with knob 323. The joint metal fitting 322 is, for example, a convex joint metal fitting, and both ends in the longitudinal direction are fixed to the hull B1 with mounting screws in a state where the horizontal bar portion 321 is sandwiched between the joint metal fitting 322 and the hull B1. At this time, a gap (space) is formed between the convex central portion of the joint metal fitting 322 and the hull B1 (upper surface), so that the horizontal bar portion 321 is inserted into this gap. The screw with knob 323 is fastened to the screw hole 325 formed in the horizontal bar portion 321 through the joint metal fitting 322, and fixes the joint metal fitting 322 and the horizontal bar portion 321.

In the present embodiment, two joint fittings 322 and two screws with knobs 323 are provided, and the horizontal bar portion 321 is fixed to the hull B1 at two locations in the longitudinal direction (left-right direction D2) of the horizontal bar portion 321. Specifically, as shown in FIG. 1, the joint metal fitting 322 is fixed to the upper surface of the gunwale (deck side) of the hull B1, and the horizontal bar portion 321 is placed on the upper surface of the gunwale (deck side) of the hull B1. In this state, the second support member 32 is attached to the hull B1. Therefore, by removing the mounting screws, the horizontal bar portion 321 can be removed from the hull B1 together with the joint fitting 322.

Further, even if the joint metal fitting 322 is left on the hull B1 side, the horizontal bar portion 321 can be removed from the hull B1 by removing the screw with knob 323. That is, the joint metal fitting 322 is fixed to the hull B1 by operating the horizontal bar portion 321 so as to be pulled out from the gap between the convex central portion of the joint metal fitting 322 and the hull B1 along the left-right direction D2. Until then, the horizontal bar portion 321 can be removed from the hull B1. In this case, the horizontal bar portion 321 is operated so as to be inserted along the left-right direction D2 with respect to the gap between the convex central portion of the joint metal fitting 322 and the hull B1, and the screw with knob 323 is tightened. Then, the horizontal bar portion 321 can be attached to the hull B1. Since the screw with knob 323 can be operated by hand without using a tool, the horizontal bar portion 321 can be attached to and detached from the hull B1 without using a tool as long as the joint metal fitting 322 is left on the hull B1. be.

Further, in the present embodiment, a plurality of screw holes 325 (here, four) for tightening the screw with knob 323 are prepared for one screw with knob 323. That is, a plurality of screw holes 325 are formed along the longitudinal direction (horizontal direction D2) of the horizontal bar portion 321. By tightening the screw with knob 323 to any screw hole 325 among the plurality of screw holes 325, it is possible to adjust the mounting position of the joint metal fitting 322 in the longitudinal direction of the horizontal bar portion 321. That is, the mounting position of the joint metal fitting 322 can be adjusted to a position corresponding to the width of the left and right gunwales (deck side) of the hull B1.

Alternatively, a screw (female screw) may be formed in the hole through which the screw with a knob 323 in the joint fitting 322 is inserted. In this case, the screw with knob 323 is tightened to the joint fitting 322 so that the tip of the screw with knob 323 penetrating the joint fitting 322 presses the horizontal bar portion 321 against the hull B1 so that the horizontal bar portion 321 It is fixed to the hull B1. As a result, regardless of the presence or absence of the screw hole 325, the horizontal bar portion 321 is attached to the left and right gunwales (deck side) of the hull B1 by the joint metal fitting 322 at an arbitrary position in the longitudinal direction (horizontal direction D2) of the horizontal bar portion 321. Can be installed. Further, a metal spacer may be inserted between the tip of the screw with knob 323 and the horizontal bar portion 321 and the tip of the screw with knob 323 may press the horizontal bar portion 321 against the hull B1 via the metal spacer.

The horizontal bar portion 321 is integrated with the tubular member 51 of the guide mechanism 41 described later, and the horizontal bar portion 321 and the tubular member 51 as a whole are formed in a T shape. The stay 324 is a component for connecting the horizontal bar portion 321 and the tubular member 51, and in the present embodiment, two L-shaped stays 324 are provided. The long sides of each of these two stays 324 are fixed to both sides of the height direction D1 of one end (left end in this embodiment) in the longitudinal direction (left-right direction D2) of the horizontal bar portion 321 with screws, and are short. The side portion is fixed to the outer peripheral surface of the tubular member 51 with a screw.

The connection structure 4 is a structure for connecting the first support member 31 and the second support member 32. As shown in FIG. 2, the coupling structure 4 has a guide mechanism 41 and a lock mechanism 42. In the present embodiment, the guide mechanism 41 includes a cylindrical member 51 and a rod-shaped member 52. The rod-shaped member 52 is inserted into the tubular member 51 along the height direction D1. The guide mechanism 41 guides the movement of the first support member 31 with respect to the second support member 32 by moving the rod-shaped member 52 in the tubular member 51 along the height direction D1. The lock mechanism 42 fixes the relative position of the first support member 31 with respect to the second support member 32 by restricting the movement of the rod-shaped member 52 with respect to the tubular member 51 in the height direction D1.

Hereinafter, a more detailed configuration of the coupling structure 4 will be described with reference to FIGS. 3 to 5. 3 to 5 are front views in which a part of the coupling structure 4 is broken, and in FIG. 3, the rod-shaped member 52 (and the first support member 31) is shown by an imaginary line (dashed-dotted line). There is.

Both the tubular member 51 and the rod-shaped member 52 are made of a metal tubular member (hollow pipe). Both the tubular member 51 and the rod-shaped member 52 have a length in the height direction D1. In the present embodiment, the tubular member 51 and the rod-shaped member 52 are both cylindrical round pipes, and are orthogonal to the longitudinal direction (here, the height direction D1) of each of the tubular member 51 and the rod-shaped member 52. The outer peripheral shape and inner peripheral shape of the cross section are circular (perfect circular shape). Since the rod-shaped member 52 is inserted into the tubular member 51, the outer diameter of the rod-shaped member 52 is equal to or smaller than the inner diameter of the tubular member 51. In this embodiment, in particular, the outer diameter of the rod-shaped member 52 is set to be smaller than the inner diameter of the tubular member 51 so that a gap is formed between the outer peripheral surface of the rod-shaped member 52 and the inner peripheral surface of the tubular member 51. .. However, the difference between the outer diameter of the rod-shaped member 52 and the inner diameter of the tubular member 51 so that the rod-shaped member 52 does not tilt significantly with respect to the tubular member 51 when the rod-shaped member 52 is inserted into the tubular member 51. Is set small. Further, the rod-shaped member 52 is longer than the tubular member 51. Therefore, as shown in FIG. 3, when the rod-shaped member 52 is inserted into the tubular member 51, the rod-shaped member 52 protrudes from at least one end surface in the longitudinal direction (height direction D1) of the tubular member 51. Become.

With the above-described configuration, when the rod-shaped member 52 is inserted into the tubular member 51, the tubular member 51 and the rod-shaped member 52 can move relatively in the height direction D1, while in the height direction D1. Relative movement in the orthogonal left-right direction D2 and front-back direction D3 is restricted. That is, according to the guide mechanism 41, the rod-shaped member 52 can be moved only along the height direction D1 in the cylindrical member 51. In other words, the relative movement of the rod-shaped member 52 with respect to the tubular member 51 in the height direction D1 is guided by the cylindrical member 51 and the rod-shaped member 52.

Here, in the present embodiment, as described above, the tubular member 51 is coupled to the horizontal bar portion 321 of the second support member 32 (at the stay 324), and the rod-shaped member 52 is the first support member 31. It is coupled (integrated) to the insertion portion 311. Therefore, for example, when the rod-shaped member 52 moves along the height direction D1 with respect to the tubular member 51 while the position of the tubular member 51 is fixed, the first support member 31 coupled to the rod-shaped member 52 The position of D1 in the height direction of is changed. On the contrary, when the cylindrical member 51 moves along the height direction D1 with respect to the rod-shaped member 52 in a state where the position of the rod-shaped member 52 is fixed, the second support member 32 coupled to the tubular member 51 The position in the height direction D1 changes. As a result, the guide mechanism 41 guides the movement of the first support member 31 with respect to the second support member 32 by moving the rod-shaped member 52 along the height direction D1 in the tubular member 51. ..

Further, in the present embodiment, the guide mechanism 41 further has a tightening screw 53 in addition to the cylindrical member 51 and the rod-shaped member 52. As shown in FIGS. 4A and 4B, the tightening screw 53 is fastened to the screw hole 521 formed in the rod-shaped member 52 through the elongated hole 512 formed in the tubular member 51. FIG. 4B is a view of FIG. 4A from one side of the left-right direction D2 (left side of FIG. 4A), that is, a right side view of the periphery of the coupling structure 4 of the float device 1, and the tightening screw 53 is an imaginary line (two). It is shown by the dotted line). The elongated hole 512 is formed in a part of the circumferential direction of the tubular member 51 (in the present embodiment, the right side surface of the tubular member 51), and is extended along the longitudinal direction (height direction D1) of the tubular member 51. ing. The screw hole 521 is formed in a part of the rod-shaped member 52 in the circumferential direction (in the present embodiment, the right side surface of the rod-shaped member 52).

Therefore, the tightening screw 53 can move in the elongated hole 512 along the height direction D1 in a state where the tightening screw 53 is loosely tightened with respect to the screw hole 521 (hereinafter referred to as “temporarily tightened state”). Therefore, if the tightening screw 53 is in the temporarily tightened state, the tubular member 51 and the rod-shaped member 52 can move relatively in the height direction D1, while the rod-shaped member 52 in the tubular member 51 can move. Rotation is regulated. That is, according to the tightening screw 53, it is only possible to directly move the rod-shaped member 52 in the tubular member 51 along the height direction D1, and the rod-shaped member 52 is twisted in the tubular member 51 ( Rotation) is also suppressed. Further, in the temporarily tightened state of the tightening screw 53, the rod-shaped member 52 can move relative to the tubular member 51 only within the movable range of the tightening screw 53 in the elongated hole 512. Here, since the movable range (top dead center and bottom dead center) of the tightening screw 53 in the height direction D1 is defined by the length of the elongated hole 512, the rod-shaped member 52 moves relative to the tubular member 51. The range will also be defined by the length of the slot 512. Therefore, as shown in FIG. 4A, the predetermined range R1 which is the movable range of the first support member 31 with respect to the second support member 32 is determined according to the length of the elongated hole 512.

Further, in the present embodiment, as shown in FIG. 2, a plurality of screw holes 521 (here, four) in which the tightening screw 53 is tightened are prepared. That is, a plurality of screw holes 521 are formed along the longitudinal direction (height direction D1) of the rod-shaped member 52. By tightening the tightening screw 53 to any screw hole 521 among the plurality of screw holes 521, it is possible to adjust the mounting position of the tightening screw 53 in the longitudinal direction of the rod-shaped member 52. That is, in the longitudinal direction of the rod-shaped member 52, a predetermined range R1 which is a movable range of the first support member 31 with respect to the second support member 32 can be set at a position corresponding to the screw hole 521. As an example, the length of the elongated holes 512 in the height direction D1 is set to 100 mm, and the pitch (interval) of the plurality of (here, four) screw holes 521 is set to 47 mm. As a result, it is possible to secure a substantially wide range of movement of the first support member 31 with respect to the second support member 32.

Further, the lock mechanism 42 moves the rod-shaped member 52 relative to the tubular member 51 along the height direction D1 by the guide mechanism 41, and then determines the relative position of the rod-shaped member 52 with respect to the tubular member 51. Fix (lock). That is, in a state where the lock mechanism 42 is not acting, the guide mechanism 41 allows the rod-shaped member 52 to move relative to the cylindrical member 51 as described above, and the lock mechanism 42 acts to restrict the movement. (It is forbidden. As a result, the relative position of the first support member 31 with respect to the second support member 32 is fixed, and the relative position of the float 2 with respect to the hull B1 in the height direction D1 (height H1 of the float 2) is positioned. ..

In the present embodiment, the lock mechanism 42 is composed of, for example, parts such as a metal band that clamps an object (cylindrical member 51 and rod-shaped member 52). That is, the lock mechanism 42 is annular and clamps the object by a tightening operation that reduces the inner diameter thereof. Specifically, as shown in FIG. 3, a notch-shaped opening in which only a part in the circumferential direction of the tubular member 51 opens in a part in the longitudinal direction (height direction D1) of the tubular member 51. 511 is formed. In the present embodiment, as an example, the opening 511 is formed on the left side surface of the tubular member 51.

As shown in FIG. 3, the lock mechanism 42 is attached to the outer peripheral surface of the tubular member 51 in accordance with the position of the opening 511 so that a part of the circumferential direction fits into the opening 511. Therefore, by the tightening operation of the lock mechanism 42, the tubular member 51 and the rod-shaped member 52 are clamped in a bounded manner by the lock mechanism 42 that has entered from the opening 511, and the relative position of the rod-shaped member 52 with respect to the tubular member 51. Is fixed. That is, the rod-shaped member 52 in the tubular member 51 is sandwiched between the lock mechanism 42 that has entered from the opening 511 and the inner peripheral surface of the tubular member 51 in the left-right direction D2, and is the inner circumference of the tubular member 51. Since it is pressed against the surface, movement in the height direction D1 is restricted (prohibited). In the present embodiment, two lock mechanisms 42 are provided, and the cylindrical member 51 and the rod-shaped member 52 are clamped at two locations in the longitudinal direction (height direction D1) of the tubular member 51. Specifically, as shown in FIG. 3, openings 511 are formed on both sides of the elongated hole 512 in the tubular member 51 in the height direction D1 and are locked at positions corresponding to the respective openings 511. The mechanism 42 is attached.

According to the float device 1 having the above-described configuration, if the tightening screw 53 is in the temporarily tightened state, the user can use the direction (downward) of the arrow D11 with respect to the tubular member 51 as shown in FIG. 4A. The height H1 of the float 2 can be adjusted by freely moving the rod-shaped member 52 in the direction (upward) of the arrow D12. At this time, the rod-shaped member 52 moves steplessly and continuously with respect to the cylindrical member 51, so that the first support member 31 with respect to the second support member 32 can be positioned at any position within the predetermined range R1. The relative position of can be adjusted. As a result, the position of the float 2 with respect to the second support member 32 (and the hull B1) in the height direction D1 can be adjusted steplessly and continuously, and the height H1 of the float 2 can be finely adjusted.

Further, the user can temporarily hold the height H1 of the float 2 by further tightening the tightening screw 53 from the temporarily tightened state (hereinafter referred to as "finally tightened state") at a desired position. can. That is, when the tightening screw 53 is in the fully tightened state, even if the locking mechanism 42 is not provided, a part of the tubular member 51 is sandwiched between the tightening screw 53 and the rod-shaped member 52, so that the strength is to some extent. , The relative position of the rod-shaped member 52 with respect to the tubular member 51 can be held. Therefore, the user does not have to continue to support the first support member 31 or the float 2 by adjusting the height H1 of the float 2 to a desired height and then setting the tightening screw 53 to the final tightening state. , The height H1 of the float 2 at that time can be maintained.

Then, the user clamps the cylindrical member 51 and the rod-shaped member 52 by performing a tightening operation of the lock mechanism 42, as shown in FIG. As a result, the relative position of the rod-shaped member 52 with respect to the tubular member 51 is fixed (locked), and the relative position of the float 2 with respect to the hull B1 in the height direction D1 (height H1 of the float 2) is fixed. .. At this time, if the tightening screw 53 is in the final tightening state and the height H1 of the float 2 is temporarily held, the user can perform the tightening operation of the lock mechanism 42 using both hands and lock the float. The tightening operation of the mechanism 42 becomes easy.

As described above, in the float device 1 according to the present embodiment, the guide mechanism 41 includes the tubular member 51 and the rod-shaped member 52, so that the mechanism is relatively simple and robust, and the second support member 32. It is possible to guide the movement of the first support member 31 with respect to. As for the lock mechanism 42, it is sufficient to restrict the movement of the rod-shaped member 52 with respect to the tubular member 51 in the height direction D1, so that the second support is provided by a relatively simple and robust mechanism such as a metal band as an example. The relative position of the first support member 31 with respect to the member 32 can be fixed.

By the way, in the present embodiment, as shown in FIG. 6A, the tubular member 51 is coupled to the second support member 32, and the upward protrusion amount A1 and the downward protrusion amount A2 with respect to the second support member 32 are formed. It's different. That is, the horizontal bar portion 321 of the second support member 32 is connected to the tubular member 51 by the stay 324, but the horizontal bar portion 321 is located at a position deviated from the center of the tubular member 51 in the height direction D1. Is combined with. In the example of FIG. 6A, the upward protrusion amount A1 of the tubular member 51 from the second support member 32 is smaller than the downward protrusion amount A2 of the tubular member 51 (A1 <A2). As a result, as shown in FIG. 6B, the height H1 of the float 2 can be significantly changed when the tubular member 51 is turned upside down and combined with the rod-shaped member 52. That is, by reversing the direction of the cylindrical member 51 to be combined with respect to the rod-shaped member 52, the height H1 of the float 2 can be adjusted beyond the movable range (predetermined range R1) in the state of FIG. 6A. ..

[4] Modification Example 1 has exemplified the float device 1 attached to the hull B1 of the sit-on type kayak, but of course, the present invention is not limited to this example, and for example, the float device to the hull B1 of the sit-in type kayak. 1 may be attached. Assuming such a case, the mounting structure of the second support member 32 (horizontal bar portion 321) to the hull B1 can be appropriately changed as shown in FIG. 7A, for example. In the example of FIG. 7A, the second support member 32 has a scissors metal fitting 326, a fastener 327, a screw 328, and a screw with a knob 329 instead of the joint metal fitting 322 and the screw with a knob 323.

In this configuration, as shown in FIG. 7B, the base end portion of the scissors fitting 326 is fixed to the horizontal bar portion 321 with the fastener 327, and the tip portion of the scissors fitting 326 is fixed to the horizontal bar portion 321 with the screw 328. It is in a state of floating from. In this state, the screw with knob 329 is tightened to the insert nut 330 in the horizontal bar portion 321 through the scissors metal fitting 326, so that one of the hull B1 is between the tip portion of the scissors metal fitting 326 and the horizontal bar portion 321. The horizontal bar portion 321 is fixed to the hull B1 so as to sandwich the portion. At this time, the second support member 32 is attached to the hull B1 from the inside of the cockpit in the hull B1 so as to sandwich the opening peripheral edge of the cockpit with a pair of scissors metal fittings 326. It is preferable that the horizontal bar portion 321 itself corresponds to both the mounting structure using the joint metal fitting 322 and the mounting structure using the scissors metal fitting 326.

In the first embodiment, an example in which the float 2 is attached to only one side (port side) of the left-right direction D2 with respect to the hull B1 is shown, but the present invention is not limited to this example, and for example, the float 2 is attached to the hull B1. It may be attached only to the other side (starboard side) of the left-right direction D2. Further, the float device 1 may be provided with a plurality of floats 2. For example, when two floats 2 are provided, the float device 1 may be provided on both the port side and the starboard side with respect to the hull B1. The float 2 may be attached. Further, it is not essential that the float 2 is attached so as to project to one side (port side) of the hull B1 in the left-right direction. It may be attached so as to come out.

Further, in the first embodiment, the tubular member 51 is coupled to the second support member 32 (horizontal bar portion 321), and the rod-shaped member 52 is coupled to the first support member 31 (insertion portion 311). This configuration is not mandatory. That is, for example, the cylindrical member 51 may be coupled to the first support member 31, and the rod-shaped member 52 may be coupled to the second support member 32.

Further, the coupling structure 4 guides the movement of the first support member 31 with respect to the second support member 32 in the predetermined range R1 along the height direction D1 by the guide mechanism 41, and at an arbitrary position within the predetermined range R1. Any configuration may be used as long as the relative position of the first support member 31 with respect to the second support member 32 is fixed by the lock mechanism 42, and the configuration is not limited to the configuration shown in the first embodiment. For example, as the lock mechanism 42, a clamp component other than the metal band may be used. As another example, the lock mechanism 42 may be configured to restrict the movement of the rod-shaped member 52 by expanding the diameter of a part of the rod-shaped member 52 in the tubular member 51. Further, the guide mechanism 41 and the lock mechanism 42 may be realized by one mechanism. For example, by rotating the rod-shaped member 52 having a screw (male screw) formed on the outer peripheral surface in the tubular member 51 having a screw (female screw) formed on the inner peripheral surface, the rod-shaped member 52 is moved to D1 in the height direction. The relative position of the first support member 31 with respect to the second support member 32 may be fixed by moving the rod-shaped member 52 and stopping the rotation of the rod-shaped member 52. As another example, the guide mechanism 41 and the lock mechanism 42 may be realized by a gear system using, for example, a worm gear and a rack.

Allows one-touch mounting of tool 2.

Specifically, both the fixing portion 61 and the attaching / detaching portion 62 are made of a metal tubular member (hollow pipe). Both the fixed portion 61 and the detachable portion 62 have a length in a direction orthogonal to the height direction D1 (here, the left-right direction D2). The fixed portion 61 and the detachable portion 62 are both square tubular pipes, and the outer peripheral shape of the cross section orthogonal to the longitudinal direction of each of the fixed portion 61 and the detachable portion 62 is a quadrangular shape (rectangular shape). The fixing portion 61 is fixed to the hull B1 by the joint metal fitting 322 and the screw with knob 323 (see FIG. 9). On the other hand, in the detachable portion 62, one end portion (left end portion in the present embodiment) in the longitudinal direction (left-right direction D2) is coupled to the tubular member 51 (at the stay 324).

When the attachment / detachment portion 62 is attached to the fixing portion 61, the fixing portion 61 and the attachment / detachment portion 62 are arranged side by side in the height direction D1 so as to be parallel to each other, and the attachment / detachment portion 62 is above the fixing portion 61. Located (see Figure 9). In short, in the present embodiment, basically, the function of the horizontal bar portion 321 in the first embodiment is provided separately in the fixed portion 61 and the detachable portion 62. In other words, the horizontal bar portion 321 in the first embodiment is divided into two parts (fixing portion 61 and attachment / detachment portion 62), and can be attached with one touch as an attachment structure between the fixing portion 61 and the attachment / detachment portion 62. Structure is adopted.

The first one-touch joint 63 is fixed to the upper surface of the fixing portion 61. The second one-touch joint 64 is fixed to the lower surface of the detachable portion 62. The first one-touch joint 63 and the second one-touch joint 64 are paired one-touch joints that are also used for connecting metal pipes to each other, for example. The fixing screw 65 with a knob is tightened to the insert nut 611 in the fixing portion 61 through the through hole 621 of the attaching / detaching portion 62.

According to the above configuration, in the first one-touch joint 63 and the second one-touch joint 64, as shown in FIG. 9, the second one-touch joint 64 becomes the first one-touch joint 63 along the axial direction (height direction D1). By pressing, they are connected (connected) to each other. In short, in the example of FIG. 9, the user operates the detachable portion 62 to which the second one-touch joint 64 is fixed so as to be pressed downward from above the fixed portion 61 to which the first one-touch joint 63 is fixed. As a result, the first one-touch joint 63 and the second one-touch joint 64 can be connected (connected) to each other. With the first one-touch joint 63 and the second one-touch joint 64 coupled, the user tightens the fixing screw 65 with a knob to the insert nut 611 in the fixing portion 61 to attach the attachment / detachment portion 62 to the fixing portion 61. On the other hand, fix it securely.

When removing the attachment / detachment portion 62 from the fixing portion 61, the user removes the fixing screw 65 with a knob from the fixing portion 61 (insert nut 611), and further releases the connection between the first one-touch joint 63 and the second one-touch joint 64. The disconnection of the first one-touch joint 63 and the second one-touch joint 64 is realized by, for example, an operation of pulling up the flange portion of the second one-touch joint 64 (upward).

It is possible. Then, when attaching the float 2 to the hull B1, the attachment / detachment portion 62 may be attached to the fixing portion 61 by a one-touch operation of pressing the attachment / detachment portion 62 against the fixing portion 61 in one direction (downward in this embodiment). Therefore, the float 2 can be attached to the hull B1 with a simple operation. Further, even if the connection between the first one-touch joint 63 and the second one-touch joint 64 is released by the fixing screw 65 with a knob, the detachable portion 62 can be reliably fixed to the fixing portion 61. Since the fixing screw 65 with a knob can be operated by hand without using a tool, in the configuration of the present embodiment, the float 2 can be attached to and detached from the hull B1 without using a tool.

The various configurations described in the second embodiment can be appropriately combined with the various configurations (including modifications) described in the first embodiment. For example, as shown in FIG. 10, the attachment structure of the fixing portion 61 to the hull B1 may be an attachment structure using scissors metal fittings 326. That is, in the modified example shown in FIG. 10, instead of the joint metal fitting 322, the same scissors metal fittings 326, fasteners 327, screws 328, and screws with knobs 329 as in FIGS. 7A and 7B described as the modified examples of the first embodiment are used. The fixing portion 61 is attached to the selection B1 using the above. In this case, it is preferable that the fixing portion 61 itself corresponds to both the mounting structure using the joint fitting 322 and the mounting structure using the scissors fitting 326.
