Description

Specification

Technical field of portable folding port

The present invention relates to a portable port, particularly a highly safe port that can be easily folded and can be easily assembled when used.

Background art

In the conventional portable port, each part that composes the hull is separately formed, and these parts are integrated by using appropriate connecting tools, bonding, fusion, or the like, or a flat plate is provided with a folding line. Some are foldable. However, they are prone to breakage at the connection points, and in particular, repeated folds inevitably shorten the life of the folded parts due to fatigue. Many materials were made of hard plastic or rubber, and were not necessarily lightweight.

Also, in the conventional portable folding port, there was a problem that the structure for expanding from the folded state and holding the side part opened was complicated, and the assembling work could not be performed smoothly.

Disclosure of the invention

The present invention is a novel portable folding port that does not have these drawbacks. The material is lightweight by using a water-resistant flexible resin, and the port body is structurally hollow blow-molded so that Provide a port that is formed, does not require any special fittings or connecting means, and is automatically folded unlike the conventional foldable port, and can be assembled easily by expanding the shore side when used. It is assumed that.

The present invention further provides a simplified portable connection structure between a support plate and a hull sandwiched between a ship and a stern at a bow and a stern in order to maintain a widened state on a ship's stern side, thereby facilitating assembly work. Another object of the present invention is to provide a folding port. That is, the portable folding port according to the present invention is formed of a hollow blow molded body mainly made of a flexible synthetic resin that allows the left and right port sides to expand and rise from the bottom of the ship and to be freely folded back on the bottom of the ship. A rectangular rod-shaped holding material is fixed along the longitudinal direction of the side surface on each of the upper edges of the port side portions of the hull, and the support plates are detachably held between the facing holding materials. Thus, the expanded state of the port side portion is maintained. With this structure, the connection between the support plate and the hull can be easily established, and the work of expanding and opening the side of the side from the folded state can be performed very smoothly.

Further, in the portable folding port according to the present invention, a hole for a mast is provided in a support plate on the bow side, and a mast support for holding a lower end of the mast is attached to the bottom of the hull at a position directly below the hole, for sailing. The mast can be easily attached and detached. This makes it possible to enjoy both rowing by the oar and sailing by the sale.

Further, the portable folding port of the present invention is configured such that a float formed separately from the hull is attached to each side of the hull, and the hull and the float are provided with connecting projections, respectively. The two pieces of E-rings pass through the other projecting piece from the lower side of the projecting piece on the lower side to the upper side. It is fitted and then a nut is fixed. This not only allows the hull and float to be separated during transportation, but also prevents the port from falling off the projecting pieces. Since the port cannot fall off, there is no problem such as dropping the port when assembling on the sandy shore and attaching the sand to the threads due to the machine oil, making assembly impossible.

In addition, the portable folding port according to the present invention is provided with a plurality of all-clutches having a vertically rotatable ring on the upper edge of the side of the side, and a fixing piece that hooks on the base of the ring to suppress rotation. It can be configured to include. As a result, when the port is advanced by rowing using the oar, unnecessary movement and friction noise of members caused by the movement of the ring are eliminated, and the oar can be operated smoothly. Further, the portable folding port of the present invention is provided with hooks for hooking on the upper edge of the side of the board, at both ends of a flat sheet plate passing between the ridges provided from the bow side to the stern side on the inside of the hull at the corresponding positions on the left and right side. A configuration in which a body is provided can be adopted. The hook body can be made of a mouth-to-top board material, but when a person sits on the seat board and applies a load, the upper edge of the side of the boat side falls inward on both the left and right sides, making strong contact with both ends of the sheet board. Then, the position of the sheet plate is fixed.

The portable folding port according to the present invention has a length corresponding to the space at the time of opening on the side of the ship and has V-shaped cuts at both ends. An opener for maintaining the widened state of the opener is provided, and one end of the opener is extended and used as a handle, whereby the open side can be pushed open. This makes it very easy to expand the hull, especially in winter when the resin composing the hull hardens.

In the portable folding port according to the present invention, the outboard motor can be attached to the stern-side support plate to enjoy the cruising.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, an embodiment of the present invention will be described with reference to the drawings.

The hull 1 is entirely formed as a single molded body by hollow molding of a water-resistant flexible resin composition. For example, as can be seen from FIGS. 1 to 5, the overall shape is substantially a spindle shape and a cross section. The shape is almost flat elliptical. The hull 1 has a bottom 2 on one side and an incision on the other side from the bow 3 to the stern 4 along the central longitudinal direction to form left and right port sides 5,5. Both sides 5, 5 are formed by this incision They face each other through the slit 6. The hull 1 is expanded by fitting a plate 7 between the sides 5 and 5 on both sides of the stern. The stern of the hull 1 is cut off so that the sides 5 and 5 can be expanded. For this reason, the stern 3 and 4 have a cover 8 to prevent water from entering. The cover 8 has flexibility such as a waterproof cloth.

The curved connecting portion 9 between the bottom 2 and the side 5 is made slightly thicker than the other part of the hull 1 and is sufficient when the side 5 is expanded from the bottom 2 to stand up. It has resilience. For this reason, the sides 5 and 5 can be expanded and opened to the right and left outward from the slit 6 and restored from the expanded state by the restoring force of their own flexibility so that they can be folded on the bottom 2 of the ship. I have. Further, since the curved connecting portion 9 is made thicker than the other portions of the hull 1 and has sufficient flexibility and durability, even if the expanding and rising operations on the side of the side 5 and the restoring and folding operations are repeated. Does not cause damage.

Further, a pair of handles 10 are provided on the stern 3 and 4 of the hull 1 on the side of the bottom 2 of the hull, respectively, so that they can be gripped during transportation or the like and can be attached with ropes when mooring. is there. The support plate 7 is a plate material having a substantially trapezoidal shape as a whole as shown in FIG. 6 and the like, and is formed by, for example, a water-resistant resin composition. The trapezoidal shape of the bearing plate 7 corresponds to the expanded shape of the edge of the shore 5 of the stern 3, 4 when the shore 5, 5 is expanded and raised. The support plate 7 is fixed to the hull by four ports 11, and therefore a rod-shaped holder 12 for fixing the support plate 7 is fixed to the upper green inside the side part 5. The support plate 7 can be bridged and fixed between the opposed holders 12 and 12 on both sides, and serves as a holding member for the expanded state of the side portions 5 and 5 and also constitutes a bow deck. .

In addition, since both ends of the support plate 7 are relatively tightly held by the restoring force of the side portions 5 and 5, if irregularities are provided by forming a groove in the short side direction of the upper surface of the holder 12 or the like, The bearing plate 7 can be prevented from slipping and moving in the bow direction, eliminating the need for fixing with the port 11 You can also. In addition, the support plate 7 can be seated by an occupant or can be used in place of a table.

Further, as shown in FIG. 7, a hole 13 can be provided in the support plate 7 to hold the mast 14 through.

The mast 14 is inserted into the hull 1 through the hole 13 of the support plate 7, and the lower end is held by the mast support 15. As shown in FIGS. 8 and 9, the mast support 15 includes a support 16 of the mast 14 and three mounting pieces 17 formed to protrude outward from the support 16. Become. The support 16 is made of a synthetic resin like the hull 1 and has a substantially hemispherical bowl-like shape with a hole 18 through which the lower end of the mast 14 is inserted. Of course, the hole 18 is located immediately below the hole 13 of the support plate 7 as shown in FIG. 7, and the diameter thereof is substantially the same.

The edges of the hole 13 of the support plate 7 and the hole 18 of the support 16 are provided with notches 20 and 21 at the corresponding positions, into which the projections 19 provided at the lower end of the mast 14 can be inserted. . The projections 19 and the notches 20 and 21 are for retaining the mast 14, and the notches 20 of the support plate 7 are for passing the lower end of the mast 14 having the projections 19. It is. That is, the projection 19 of the mast 14 is aligned with the notch 20 of the support plate 7, and the lower end of the mast 14 is inserted into the hull 1, and the projection 19 is further aligned with the notch 21 of the support 16. Then, when the lower end of the mast 14 is inserted into the hole 18 of the support 16 and the mast 14 is rotated by an appropriate angle, the projection 19 is hooked on the edge of the hole 18 to prevent it from falling out. This also allows the mast 14 to rotate around its axis. The liner 22 should be SB inside the support 16 so that the lower end of the mast 14 does not directly touch the bottom 2 of the ship.

In the outfitting shown in Fig. 10, the boom 23 and the yard 24 are attached to the upper part of the mast 14 made of cylindrical pipe material at a slight angle from the parallel, and the jib sail 25 and the main sail 2 Although this is a special type in which 6 is arranged together, the port fitting according to the present invention is not limited to this example, and various types can be adopted. A single ridge 27 is formed from the bow 3 to the stern 4 on the inner side of the side portions 5, 5, and a seat 28 for seating can be laid between the ridges 27, 27. And so on. The sheet 28 is also formed of a water-resistant resin like the hull 1, and is formed in a trapezoid with both ends of a rectangular flat plate slightly tapered as shown in FIG. Further, a pair of retractable hooks 29, 29 are provided at both ends of the sheet 28, and as shown in FIG. In this state, the lower end of the seat 28 is located on the ridge 27, and can be slid in this state to freely change the position in the bow 3 direction or the stern 4 direction. In addition, the upper edge of the port side 5, 5 slightly narrows (especially when the occupant sits down, etc.), so that both ends slide in contact with the hull inner surface of the port side 5, generating a large friction. The position does not move, making the operation of the oar easier.

As shown in FIGS. 12 to 14, ropes 30 may be provided at both ends of the sheet 28 instead of the hooks 29. As shown in FIG. 13, two holes 31 are formed in the sheet 28 and both ends of the rope 30 are passed through the holes 31 to form a knot, so that the rope 30 can be easily fixed to the sheet 28. In order to fix such a sheet 28 to the side of the ship 5, a rope 30 is hooked on a knob port 32 attached to a port hole for an all clutch described later.

Referring back to FIGS. 1 to 5, the hull 1 is provided with floats 33 on both sides 5, 5. The float 33 has a rectangular cross section formed into a hull 1 with a rounded corner, and a projection 34 formed in the center longitudinal direction of the hull 1 is formed on the curved connecting portion 9 of the hull 1. It is fixed with Porto so that it can be attached and detached to 35 The float 34 is made of the same resin as the hull 1 and is filled with water and other ballast material to keep the light hull 1 stable. A long hole 36 is formed on the bow 3 side of the float 34. The slot 36 is used to insert the Senyuichi Board 37 during sailing so that it protrudes below the water surface to reduce the leeway of the hull 1.

When the hull 1 is not floating on the water as shown in Fig. 4, It is formed so as to hang slightly diagonally downward. This takes into account the buoyancy of the float 33 when the hull 1 is placed in the water. When the hull 1 is placed on the water, the float 33 rotates upward and becomes almost horizontal.

FIG. 15 shows a structure for attaching the float 33 to the hull 1. A port 36 is penetrated upward from the underside of the ridge 35 of the hull 1, and is retained by hanging E-rings 37, 37. A thumb screw 38 is screwed into the screw portion. By doing so, the porto 36 does not fall off during traveling or transport, even if the thumb screw 38 is loosened. There is no dropout of Porto 36. Therefore, when assembling in a sandy area by the water, the Porto 36 is dropped on the sand, and the sand adheres to the machine oil attached to the screw part. No troubles such as disappearance will occur, and the work of attaching and detaching the float 33 will not be troublesome. Of course, it is very inexpensive as compared with port insert molding.

A flat stabilizer 39 can be screwed between the projections 38, 38 provided on the stern 4 side of the float 33 (Fig. 1). It can be removed and a casserole can be attached for convenient transportation.

Further, as shown in FIGS. 16 and 17, on the stern 4 side of the side of the shore 5, a base bracket 40 for mounting a ladder and an outboard motor is mounted from above the cover 8. A mount 44 for attaching the ladder 41 and the chiller 42 or the outboard motor 43 is fixed to the base fitting 40 with a support fitting 45. Fig. 10 shows how the rudder 41 and the flyer 42 are attached, and Fig. 18 shows how the outboard motor 43 is attached.

Portholes 44 are formed in the upper edge of the side part 5 at several places so that the fixing position of the clutch 45 for attaching the oar can be easily changed. In the illustrated example, the clutch 45 is formed by rotatably connecting a ring 48 for mounting an oar between supports 47, 47 provided on a U-shaped base 46.

In this clutch 45, a base 46 is fitted to the upper edge of the side 5 and a fixing screw 49 is attached to the side. It is screwed into the porthole 4 4 of 5 and fixed, but it can be laid down as shown in Fig. 2, Fig. 19 and Fig. 20 in consideration of folding during storage. Therefore, when the rowing operation is performed by inserting the oar into the ring 48, the frictional noise of the members may be intense, and the oar may not be operated smoothly. Therefore, as shown in FIGS. 21 and 22, the ring 48 is erected, and the base plate 46 is sandwiched between the base of the ring 48 and the fixing plate 50 is hung to erect the ring 48. Since the ring 48 can be rotated horizontally in this state, no noise is generated even when the oar is mounted and operated, and the ring 48 is not damaged. Etc. can be eliminated.

FIG. 23 shows an opener 51 used for the work of expanding the side of the ship 5,5. The opener 51 has V-grooves 52 and 52 at both ends, and one end is extended to form a grip 53. The work of expanding the side sides 5, 5 using this orbner 51 will be described below. First, as shown in Fig. 24, from the state where the hull 1 is folded, put the hands on the left and right sides 5 and 5 and slightly widen them. , Keep the 5 from being broken by its own resilience. Next, the opener 51 is used almost at the center of the hull 1, specifically, just next to the all-clutch 45 at the center of the hull 1 as shown in FIG. In other words, hold the grip 5 3 of the opener 5 1 in one hand, push the other side of the grip 5 3 against the inside of the 炫 side 5 on the opposite side, and at the same time, pull the front side of the ship with the other hand as much as possible, and Fit the groove 52 inside the front side 5. Then, the hull 1 is held open by the opener 51 as shown in FIG. Then, the occupant enters the hull 1, sits down, pushes the sides 5 and 5 further with his back and feet, sandwiches the seat 28 between the sides 5 and 5, and mounts the support plate 7 between the holders 1 2 and 1 2 on the side 5 It should just fit in. Then, the restoring force of the shoreside 5, 5 is received by the seat 28 and the support plate 7, and the assembly is completed. When folding this port, it is only necessary to remove the seat 28 and the support plate 7 from the assembled state as described above. Side 5 is curved Folds naturally on the bottom 2 due to the flexible restoring force provided by the connection 9 ₍
