Description

  The invention belongs to the field of sliding boards used for surfing on snow or water, skiing on snow or water, skateboarding and the like.

  The plate is conventionally traversed between a length measured along the longitudinal direction between the first end and the second end, and between the first edge and the second edge. It has a width measured along the direction and a height measured between the sliding surface (or rolling surface) and the receiving surface.

  The board has a first end section, a central section, and a second end section from a first end to a second end.

  This plate material is finally formed of a sandwich-like panel formed of a first reinforcing material and a second reinforcing material, and having a first core disposed therebetween. These reinforcements impart mechanical properties to the majority of the plate, and the core serves to fill the voids between the two reinforcements. It is to be noted that a plate member having another structure having one or a plurality of reinforcing members may be considered.

  To operate the board, the user biases the board. Such an operation is necessary particularly when surfing on snow by snowboarding, for example, when an edge of a plate material is on a slope. If the user wishes to initiate a turn, the user may shift his body's center of gravity toward one end. Then, due to the weight of the user, the end of the plate material presses the ground and tries to slide in the direction of the slope.

  At the same time, the other elongated end also catches on the ground at the edge, and the entire plate is reversibly twisted substantially along its longitudinal axis. Since one end slides along the slope and the other end does not slide, the plate turns and changes direction.

  Obviously, it is not always easy to steer by twisting the plate, as in the case of starting to change direction. Lighter weight users do not bias the plate as strongly as heavier weight users. In addition, since the short user does not shift the center of gravity so much more than the tall user, the edge of the plate material does not catch on to follow the inclination of the slope.

  One of the objects of the present invention is to facilitate the operation of the plate, especially when the plate is turned.

  For this purpose, the present invention proposes the following sliding or rolling plate. That is, a certain length between the first end and the second end, measured along the longitudinal direction, and a certain length between the first edge and the second edge along the transverse direction. Having a certain width, measured between the running surface and the foot receiving surface, the plate having at least a first reinforcing member at the top. The plate has a first end section, a central section, and a second end section from a first end to a second end.

  A feature of this plate according to the invention is that in the central area, at least one of the stiffeners has at least one structural part which is mechanically weaker than the rest of the structure of the stiffener.

  If the structure of the reinforcing member is soft, the plate member can be deformed more with a predetermined bias or the same deformation can be performed with a smaller bias. Therefore, the deformation of the plate material becomes easier with respect to various biases. In particular, a reversible twist can be more easily created at the start of the turn.

  This makes the operation of the plate material easier as a whole.

  Other features and advantages of the present invention will be better understood by reading the following description with reference to the accompanying drawings, which show, by way of non-limiting example, how the invention can be realized. I can do it.

  Although the embodiments shown herein relate to a board for snowboarding, it should be understood that other boards suitable for performing various sports as described above may be applied.

  The first embodiment of the present invention will be described below with reference to FIGS.

  As can be seen in particular from FIG. 1, the snowboard 1 has a length measured in a known manner between the first end 2 and the second end 3 along the longitudinal direction L. The plate 1 has a width measured along the transverse direction between the first side edge 4 and the second side edge 5 and a height measured between the sliding surface 6 and the foot receiving surface 7. Having

  Of course, this transverse direction is perpendicular to the longitudinal direction L and parallel to the running surface 6.

  This plate 1 also comprises a first end section 8, a first contact line W 1, a central section 9, a second contact line W 2, from the first end 2 to the second end 3. , A second end section 10. The central section 9 itself has a first intermediate section 15, a first retaining section 16, a second intermediate section 17, a second retaining section 18, a second retaining section 18, between the contact lines W1 and W2. And three intermediate sections 19 in series.

  Each holding area 16, 18 is provided for receiving a device for holding a user's foot. Although not shown in the drawing, the foot holding device is integrally attached to the plate 1 by means such as screws. For this purpose, each holding area 16, 18 is provided with a threaded hole 20.

  Each of the contact lines W1 and W2 extends substantially in the transverse direction of the plate 1 at a position where the sliding surface 6 comes into contact with a plane when the plate 1 is on the ground without receiving shadow chopsticks from the outside. The existing line segment.

  The height of the plate 1 is as shown in the cross section in FIGS.

  Between the sliding surface 6 and the foot receiving surface 7, the plate 1 has a bottom 21, a first reinforcement 22, a core 23, a second reinforcement 24, and a protective layer 25.

  Depending on the type of plate material, the number of reinforcing materials may be changed. That is, it may be 2 or less, or 2 or more.

  The bottom 21 may be made of, for example, a plastic material containing polyethylene. The protective layer 25 may be made of, for example, a plastic material containing acetyl-butane-styrene.

  Each of the reinforcing members 22 and 24 is preferably made of resin-impregnated fibers. The fibers may be made of any material. That is, it may be made of glass fiber, carbon fiber, aramid fiber, metal fiber, or the like. The core 23 includes a low-density material such as wood or synthetic foam, and has a light mass. Of course, wood and foam may be used together.

  The reinforcing members 22 and 24 and the core 23 form a sandwich panel. The panel preferably extends at least 50% of the area of the plate, preferably over substantially the entire area. This makes the structure of the plate material uniform.

  According to the invention, in the central area 9, at least one of the stiffeners 22, 24 has a structural part in which the structure of at least a part of the stiffener is mechanically weakened compared to the rest thereof. The mechanically weakened structure facilitates reversible deformation of the plate 1.

  As can be seen from FIGS. 1-3, according to a first embodiment of the present invention, it is the second stiffener 24 that has the first portion 30 of the mechanically weakened structure. This first part 30 is in a second intermediate area 17 which is between the holding areas 16 and 18. The first portion extends along substantially the entire second intermediate section 17 from the first edge 4 to the second edge 5 and between two sets of threaded holes 20. . Localizing such a weakened portion facilitates reversible deformation between the holding areas 16 and 18 (and thus the user's feet).

  This mechanical weakness of the first portion 30 is achieved by reducing the amount of material used for the second reinforcement 24. This material reduction is achieved by removing the material, for example by machining. It is therefore sufficient to make the plate 1 using conventional reinforcements and then machine the plate, for example with a milling machine. The protective layer 25 is processed simultaneously with the reinforcing material. This technique has the advantage of being simple to fabricate.

  Of course, other techniques may be used. For example, the reinforcing member 24 may be cut out before assembling the components of the plate material.

  According to the first embodiment of the present invention, the material is reduced by performing grooving.

  The second reinforcing member 24 includes a first groove 31 located near the first side edge portion 4, a second groove 32 located substantially between the side edge portions 4 and 5, and a second It has a third groove 33 located near the side edge 5, but is not limited to this embodiment. Each of the grooves 31, 32, 33 has a substantially linear shape and is oriented substantially along the longitudinal direction L of the plate 1.

  This arrangement slightly reduces the area of the stiffener 24 in the transverse direction, but significantly reduces the area in the longitudinal direction. Thus, the plate 1 continues to significantly retain its bending resistance along the transverse pong within the second intermediate section, but within the second intermediate section, the torsional resistance along the longitudinal axis. Lose a little. Therefore, it is easier to twist the plate material along the longitudinal direction. This twist manifests itself in better performance in the operation of the board, inclining the holding sections 16, 18 or the first intermediate section 15 and the third intermediate section 19 at different angles. For this reason, the movement of the center of gravity of the user at the ends 2 and 3 of the plate material makes one of the ends 2 and 3 slide well, and in combination with this, the hooking of the other end becomes good. Therefore, it becomes easier to inscribe the plate 1 when cutting a curve.

  The groove may have a length of 5 to 50 cm, a width of several tens mm to several centimeters, and a depth of several tens mm to several centimeters.

  Each groove 31, 32, 33 passes through the stiffener 24, but this is not essential.

  Each of the grooves 31, 32, and 33 preferably has a square or rectangular cross-sectional shape, but may have another shape (for example, a rounded shape).

  In the length direction, each groove may be linear or non-linear. For example, the grooves may be curved in the longitudinal direction and may form a series of line segments, but may be spaced apart from each other or may include both curved and straight portions simultaneously.

  The number of grooves is not limited to three, and may be more or less than three.

  These grooves may be the same length or may differ in length from each other.

  A plurality of grooves may be separately arranged, or may be arranged on a straight line.

  3, three fittings 34, 35, 36 are provided in three grooves 31, 32, 33, respectively. Each fixture extends to the protective layer 25, the second reinforcement 24, and the core 23. Each fixture improves the finished condition of the receiving surface 7. Each of the fixtures 34, 35, 36 makes the structure of the plate 1 nectar so that water does not in particular enter between the core 23 and the reinforcing member 24.

  The fittings 34, 35, 36 can be made of a plastic material such as, for example, acetyl-butadiene-styrene or polyurethane.

  The fixtures 34, 35, 36 are added to the board structure, preferably by gluing. This is because the glue material makes the grooves 31, 32, and 33 into nectar. However, other techniques are also conceivable, such as, for example, techniques using a flexible attachment that is forcibly attached to form a seam.

  The fittings 34, 35, 36 may have any cross-sectional shape such as a U-shape, a solid shape, and a hollow shape. This fixture serves to reduce or avoid snow filling the grooves 31, 32, 33. In either case, the mountings can also reduce vibrations applied to the plate.

  Another embodiment of the present invention is described below. For convenience of explanation, singular points are mainly described as compared with the above-described first embodiment.

  The second embodiment will be described with reference to FIG.

  The plate member 50 is formed at a certain height by a laminated member including a bottom portion 51, a first reinforcing member 52, a core portion 53, a second reinforcing member 54, and a protective layer 55. According to the present invention, the groove 56 penetrates the protective layer 55, the second reinforcing member 54, and a part of the core 53, and is provided on the upper part of the plate member 50. Compared to the first embodiment, the fixture 57 extends only along the core and forms the bottom of the groove 56 by being flush with the second stiffener 54 near the core 53. I do.

  The structure of the plate material shown above can be manufactured by the procedure described below.

  Only the core 53 is formed, and the attachment 57 is attached. Next, the above-described laminated member is formed and disposed in a mold. When the temperature and the pressure are increased, the members constituting the plate member 50 are integrally connected to each other. Finally, the groove 56 is formed by removing the material by, for example, machining. According to this manufacturing method, the attachment 57 is arranged at a predetermined position during the intermediate work. The attachment 57 may be machined simultaneously with the groove 56, in which case the groove itself need not be machined.

  The third embodiment of the present invention will be described with reference to FIG.

  The plate 70 is formed at a certain height by a laminated member including a bottom 71, a first reinforcing member 72, a core 73, a second reinforcing member 74, and a protective layer 75. According to the present invention, the groove 76 penetrates the bottom 71 and the first reinforcing member 72 and is provided at the lower part of the plate member 70. The groove 76 is closed with a fitting 77 that prevents, inter alia, water from entering. This fitting may be made of the same or similar material as the material forming the bottom 71. This fixture has a tendency to keep the bottom 71 sliding well. The technical effect obtained by the softness of the first reinforcing member 72 is the same as the technical effect obtained by the softness of the second reinforcing member.

  A fourth embodiment of the present invention will be described with reference to FIGS.

  As can be seen in FIG. 6, the plate 90 has a first end 91, a second end 92, a first side edge 93, a second side edge 94, a sliding surface 95, and a receiving surface 96. .

  The plate 90 has a first end section 97, a first contact line W3, a central section 98, a second contact line W4, and a second end section 99.

  In the central section 98, the plate 90 has a first intermediate section 105, a first retaining section 106, a second intermediate section 107, a second retaining section 108, and a third intermediate section 109. Each holding area 106, 108 has a threaded hole 110.

  As shown in FIGS. 7 and 8, the plate member 90 includes a bottom 111, a first reinforcing member 112, a core 113, a second reinforcing member 114, and a protective layer 115 in the height direction. Including.

  Furthermore, in accordance with the invention, in the central area 98, at least one of the stiffeners 112, 114 is provided with at least one structural part that is mechanically weaker than the rest of the stiffener structure. This softness facilitates reversible deformation of the plate 90.

  As can be seen from FIGS. 6, 7 and 8, according to a fourth embodiment of the present invention, it is the second stiffener 114 having the first portion 120 of the mechanically weakened structure. This first portion 120 is contained within a second intermediate zone between the holding zones 106,108. The first portion 120 extends substantially from the first side edge 93 to the second side edge 94 and between the two pairs of threaded holes 110 over substantially the entire second intermediate section 107. Extending. This placement of the soft portion allows for reversible deformation between the holding areas 106, 108 (and thus between the user's feet).

  The second stiffener 114 has a ridge 121 that imparts mechanical weakness to the first portion 120.

  Each ridge 121 reduces the thickness in the direction in which the reinforcement 114 extends.

  The ridge groove 121 extends substantially in the longitudinal direction of the plate material 90. Some of these ridges are near the side edges 93, 94 of the plate, and others are between the side edges 93, 94.

  These ridges 121 may have different lengths, different depths, and different shapes.

  As can be clearly understood from FIG. 8, the ridge groove 121 has a rounded shape. This shape avoids or at least reduces the risk of initiating breakage of the stiffener 114. The shape is not limited to the rounded shape, and ridges having other shapes may be employed.

  As can be clearly seen from FIG. 6, the arrangement of the ridges 121 is made in accordance with a pattern reminiscent of the shape of “diaboro”. This arrangement is exemplary and may be any other arrangement.

  Plate 90 is made in a manner that can be better understood with reference to FIG.

  The bottom 111, the first reinforcement 112, the core 113, the second reinforcement 114, and the protective layer 115 are laminated in a mold 130. The mold includes a pedestal 131 and a lid 132. The mold 130 is closed, the mold is pressurized, and the temperature of the mold is increased, thereby applying a bonding force to the plate 90. The ridge groove 121 is formed by a langet (small tongue-shaped portion) 133 arranged in the lid of the mold 130. At the place where the langet 133 is pressed, the reinforcing member 114 is deformed to become the ridge 121. This phenomenon acts like a knife that cuts material by causing the pressure of the languet 133 to rise. Moreover, prior to solidification, the reinforcement 114 can be easily deformed. In fact, the stiffener 114 is a mixture of high viscosity resin and fiber. In this way, overpressure is localized. Prior to the solidification of the resin, the movement of the fibers in the reinforcement 114 causes the ridge 121 to be formed. The fibers press both sides of the ridge 121.

  It is clear that by maintaining a substantially constant thickness, the protective layer 115 naturally conforms to the shape of the reinforcement 114.

  The structure of the ridges 121 reduces the transverse extent of the stiffener 114 only slightly, but significantly reduces its longitudinal extent. Thereby, the plate 90 substantially completely preserves the bending resistance in the second intermediate section 107 along the transverse axis. However, the plate 90 loses little torsional resistance in the second intermediate section 107 along the longitudinal axis. Therefore, it becomes easier to twist the longitudinal pongee. This improves the inscribing of the plate 90 when cutting a curve.

  For all of the embodiments described above, the present invention can be implemented using a variety of materials and according to techniques known to those skilled in the art.

  Of course, the present invention is not limited to the various embodiments described above, but includes any equivalents that can fall within the scope of the utility model registration claims described at the outset.

  In particular, regarding the plate material, the portion where the soft working is performed may be either the first reinforcing material, the second reinforcing material, or both.

  For the same plate, the soft working techniques may all be uniform or may be different.

  The softened portion may extend into the retaining area or may extend beyond the retaining area.

  The present invention is not limited to snowboards, but can be applied to any kind of sliding or rolling boards having the same or similar problems to be solved.
