Description

  The present invention relates to an accessory worn by a board sailor when performing windsurfing, and more particularly to a waist harness for windsurfing.

  Windsurfing is a sport in which a rig is attached to a board and the power of wind is used to glide lightly on the surface of the water. The board running on the surface of the water mainly consists of board and skeg. The rig that receives wind mainly includes a sail that directly receives wind, a mast that is attached to the board and supports the sail, and a boom that operates the sail around the mast. Board sailors place their feet on the board while sliding on the surface of the water, hold the boom with both hands and operate the sail's direction, angle of inclination, etc. It may be difficult to endure and operate efficiently. Therefore, the board sailor wears an attachment with a hook on the waist, and hooks the hook on a harness line provided at a predetermined position of the boom, thereby making it easy to deposit weight on the boom. Such wearing devices are roughly classified into a waist harness that can be worn on the waist and a seat harness that can be worn on the hip, depending on the part where the board sailor is worn.

  While sliding, a very large force and load are applied to the harness, but the conventional waist harness, in particular, lacks rigidity, so the back and abdominal muscles do not support the load whenever the lumbar region is twisted or distorted. The burden on the lower back of the board sailor was very heavy.

  Furthermore, in addition to the lack of rigidity at the waist part of the conventional waist harness, the support of the harness to the board sailor was only the waist belt and the waist area, effectively preventing the hook from rising. I couldn't.

  Conventionally, there is a seat harness that can prevent the phenomenon of the hook being lifted. With this seat harness, the force applied to the hook is received not only at the waist but also at the hip. In the conventional seat harness, since the thigh belt is hung from the hip portion to the front lower portion of the waist belt with respect to both thigh portions of the board sailor, it is possible to prevent the hook itself from rising. However, since the thigh is always pulled upward by the thigh belt when worn, the freedom of the lower body greatly restricts its movement.

  Accordingly, one object of the present invention is to provide a waist harness that can reduce the burden on the waist by increasing the rigidity of the waist.

  Another object of the present invention is to provide a waist harness that can prevent the hook from rising without providing a thigh belt in a conventional seat harness and does not restrict the movement of the lower body at all. It is.

  According to one aspect of the present invention, a central part and a body of the board sailor are integrally extended from the central part in both directions in order to support the hips of the board sailor as a reinforcing part. For windsurfing consisting of a waist part consisting of a pair of side waist parts supporting up to the vicinity of the flank, and a pair of waist belts each of which is fixed to the side waist part and fastened at the other end near the abdomen of the board sailor In the harness, there is provided a windsurfing harness characterized in that a carbon material is included as one of the plurality of materials constituting the polymer.

  In the windsurfing harness, the carbon material may be attached to at least one surface of another material among the plurality of materials constituting the polymer.

  In the windsurfing harness, it is preferable that the carbon material is adhered to the entire surface of the other material among the plurality of materials constituting the polymer with an epoxy resin or the like.

According to another aspect of the invention,
A central part for supporting the hips of the board sailor and a board sailor extending in both directions integrally from the central part having a reinforcing part containing a carbon material as one of a plurality of materials constituting the polymer. A waist part composed of a pair of side waists supporting up to the vicinity of the flank;
A pair of waist belts, each one end being fixed to the side waist and the other end being fastened near the abdomen of the board sailor,
A hip portion provided integrally below the central portion for supporting the hip of a board sailor;
A hip extension extending integrally from the hip portion and separated from the side waist;
A pair of hip belts, one end of which is fixed to each of the hip extensions, and the other ends are fastened near the lower abdomen of the board sailor,
A windsurfing harness characterized by comprising:

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a windsurfing waist harness 10 according to a first embodiment of the present invention as viewed from the waist side. FIG. 2 is a view when the waist harness 10 is worn on the mannequin as viewed from the side. In FIG. 2, the left side of the drawing is the ventral side, and the right side is the waist side. The windsurfing harness 10 of the illustrated embodiment is integrally extended from the waist part of the board sailor, more specifically, a wide central part 12 that supports the hip part, and both sides of the central part 12, A pair of waist belts that support from the waist to a part of the abdomen, and one side is firmly sewn to the side waist part 13 and the other ends are fastened near the abdomen of the board sailor; Consists of. In the drawing, this waist belt is not drawn, but is fastened to each other in the vicinity of the abdomen of the board sailor by, for example, a surface fastener. Reference numeral 16 indicates a hook for hooking to a harness line provided at a predetermined position of the boom at the time of sliding. The hook 16 is fixed to the waistside portion 13 of the harness 10 by a hook belt indicated by reference numeral 14.

  Although the conventional waist harness can be said to be almost the same as that of the first embodiment described above, the windsurfing harness 10 according to the present invention and the conventional harness support the center of the hips of the board sailor. The internal configuration or structure of the portion 12 is greatly different. Although the conventional harness is not shown, the central portion typically has a foamed resin core that also functions as a slightly thicker cushion between the inner skin and the outer skin that directly touch the waist, and rigidity is provided. For this reason, a plastic plate for the purpose of polymerization is superposed and stitched around its periphery. In the conventional harness, since the rigidity was obtained by the plastic plate, sufficient rigidity could not be achieved. Therefore, every time the hips were twisted or distorted during sliding, the back and abdominal muscles had to be supported, and the burden on the hips was very heavy.

  A feature of the windsurfing harness 10 according to the present invention is that it includes a carbon material as one of the polymers. As an example, a carbon material is attached to a conventional plastic plate with an epoxy resin as an example. The carbon material may be attached to either the front side or the back side of the plastic plate, but may be attached to both sides if necessary. Furthermore, as the sticking mode, it is most common to put it on the entire surface of the plastic plate. However, considering the necessary strength and flexibility, the plastic plate is partially spaced, for example, at an appropriate interval. It may be applied in a stripe shape. As another aspect, a carbon plate made of a carbon material can be used as it is instead of the plastic plate. In addition to the plastic plate, a carbon plate can be additionally used.

  FIG. 3 is an example of a cross-sectional view of the central portion 12 of the windsurfing harness 10 of the present invention, and shows a cross section of an embodiment in which a carbon material is adhered to the surface of a plastic plate. Specifically, the polymer of the harness 10 according to the present invention has a cloth inner skin 22 that directly touches the waist, a foamed resin core 24 that mainly functions as a cushioning material, and a carbon material 25 that is a feature of the present application. It consists of a polymer of a plastic plate 26 and a cloth outer skin 28. In the drawing, for the sake of illustration and explanation, a space is shown between the members. However, in an actual polymer, the members may be in contact with each other. The carbon material 25 is light in weight, hard, and has a feature that is extremely rich in flex properties. By using the plastic plate 26 to which the carbon material 25 having such characteristics is attached as one of the superposition members constituting the central portion 12, the force received by the hook 16 is reduced to the waist portion, particularly the center thereof. Since the plastic plate 26 to which the carbon material 25 constituting the portion 12 is adhered is supple, the twist and distortion of the entire harness can be efficiently prevented. As a result, the necessity for the board sailor to support the load with the back and abdominal muscles during the sliding is greatly reduced, and the burden on the waist is reduced.

  FIG. 4 is a view of a state in which the windsurfing harness 30 according to the second embodiment of the present invention is worn on a mannequin as viewed from the side. In the figure, the left side of the drawing is the abdomen and the right side is the waist. A difference from the waist harness 10 of the first embodiment shown in FIGS. 1 and 2 is that a hip portion 36 having a cushion core material for supporting a hip of a board sailor is provided at the lower portion of the center portion 32 below the waist portion. Hip extension portions 37 that are integrally provided so as to be bent with respect to the central portion 32 of the lip portion and that extend from the opposite sides of the hip portion 36 to the front side of the lumbar portion 33 and forward. And a pair of hip belts 38, 38 are provided at the tip of the extension 37. The configuration of the central portion 32, the side waist portion 33, and the pair of waist belts 34, 34 is the same as the center portion 12, the side waist portion 13, and the waist belt of the harness 10 of the first embodiment described above. The structure of the polymer in the central portion 32 is the same as that of the first embodiment shown in FIG. That is, as an example, a plastic plate in which a carbon material is bonded to an plastic plate with an epoxy resin is used as one of the constituent members constituting the polymer. Reference numeral 39 indicates a hook, and the hook 39 is fixed to the harness 30 using a hook belt 40 or the like.

  By adopting the configuration of the second embodiment described above, the force F applied from the harness line to the hook 39 during the sliding is surely in the directions indicated by the arrows Fa and Fb in FIG. Since it is dispersed, it is possible to efficiently prevent the harness from rising without using a crotch belt like a conventional seat harness. Therefore, the movement of the lower body of the board sailor is not restricted.

FIG. 1 is a perspective view of a windsurfing harness according to a first embodiment of the present invention when viewed from the waist side. FIG. 2 is a view of the harness wearing state according to the first embodiment of the present invention as seen from the side. FIG. 3 is a cross-sectional view showing the structure of the polymer at the center of the waist portion of the harness according to the present invention.
