In other words, a course Q (sometimes called a floor or a section) in which the sliding sports equipment S can run is formed by assembling a plurality of course forming bodies 1 and 1 so as to be brought into contact with each other (connected adjacently). To do.

As shown in FIGS. 1 and 2, a short cylindrical male portion 3 is disposed on one of the connection facing surfaces K and K of the course forming bodies 1 and 1 to be assembled in contact with each other. The female part 2 having a concave recess 80 having a circular cross section is inserted into the male part 3 so as to be freely inserted and removed.
The male part 3 is provided in the lower part (lower side member 18) of the base frame 10 of one course formation body 1. FIG.
The female part 2 is provided in the lower part (lower side member 18) of the base frame 10 of the other course forming body 1.

  As shown in FIGS. 3 and 4, the male portion 3 has the same shape and size (same shape and same size) as the short metal cylindrical member 6 having the insertion portions 60 and 60 at both ends and the female portion 2. And a base 5.

  The short columnar member 6 has tapered guide surfaces 61, 61 that are reduced in diameter toward the outer ends on the outer peripheral surfaces of the insertion portions 60, 60, straight reference outer peripheral surfaces 62, 62 for alignment, have. Furthermore, screw holes 67 and 67 are provided along the axis La of the short columnar member 6 at both ends (both end surfaces of the insertion portions 60 and 60).

As shown in FIGS. 4 and 5, the base portion 5 and the female portion 2 are composed of a metal short cylindrical receiving member 8 that is the same component.
The receiving member 8 (the base portion 5 and the female portion 2) includes a tapered guide inner peripheral surface 81 that decreases in diameter from the opening edge toward the inside of the hole, and a hole inner end of the guide inner peripheral surface 81. A straight reference inner peripheral surface 82 formed continuously at the edge, and a tapered inner peripheral surface 83 formed continuously from the hole inner end edge of the reference inner peripheral surface 82 and having a diameter decreasing toward the inside of the hole; And a hole bottom surface 84.
The receiving member 8 has a bolt shaft portion insertion hole 87 that is coaxially arranged with the recessed portion 80 and communicated with the recessed portion 80.

  The receiving member 8 is fixed to a vertical surface mounting member 17 fixed to the back surface of the lower side member 18 of the base frame 10 by a plurality of screw members in a horizontally projecting manner. The mounting member 17 is plate-shaped and has a bolt mounting through hole 17 a communicating with the bolt shaft portion insertion hole 87 of the receiving member 8.

As shown in FIG. 4, the male portion 3 is shortly inserted into the recessed portion 80 of the base portion 5 by inserting one of the insertion portions 60 and 60 of the short cylindrical member 6 into the reference inner peripheral surface 82 of the recessed portion 80. The reference outer peripheral surface 62 of the cylindrical member 6 corresponds, and the recessed portion 80 and the short cylindrical member 6 are arranged coaxially. Further, in the male part 3, the bolt member 7 inserted through the bolt shaft part insertion hole 87 is screwed into one screw hole part 67, and one of the insertion parts 60, 60 of the short columnar member 6 is inserted into the recessed part 80. Is configured to be freely inserted and separated.
In the example shown in the figure, a gap is formed between the end surface of the short cylindrical member 6 and the hole bottom surface 84 of the base 5, but they may be brought into contact with each other.
Further, in the illustrated example, a gap is formed between one tapered guide surface 61 of the short columnar member 6 and the tapered inner peripheral surface 83 of the base portion 5, but they may be brought into contact with each other.

  And as shown in FIG. 3, when the course formation bodies 1 and 1 are brought into contact with each other in an appropriate arrangement (assembled), the axial center La of the male part 3 (the short columnar member 6 and the base part 5), The axial center Lb of the female part 2 is provided so as to be coaxial.

As shown in FIG. 6, the lower end portion of the jack bolt member 13 is set to the upper position from the installation surface G, and the plug is ready for insertion (running) by the wheels 12.
Then, the course forming bodies 1 and 1 are moved by the operator's hand, and the course to be assembled so that the axial center La of the male part 3 and the axial center Lb of the female part 2 are coaxial. The connection facing surfaces K and K of the formed bodies 1 and 1 are brought close to each other. Even if the axial center La of the male part 3 and the axial center Lb of the female part 2 are slightly displaced from the coaxial center position, the tapered guide surface 61 of the male part 3 (the other of the short cylindrical members 6), The male part 3 is inserted into the female part 2 while the guide inner peripheral surface 81 of the female part 2 is in sliding contact with each other and is guided coaxially (alignment). That is, the course forming bodies 1 and 1 are arranged at appropriate positions.

  Here, in the vicinity of the male part 3 and the female part 2 of the connection facing surfaces K, K that are brought close to each other, contact surfaces 10d, 10d serving as assembly completion criteria (former contact completion criteria) are provided. Provided. More specifically, the contact surface 10d is the vertical surface (front surface) of the lower side member 18 corresponding to the connection facing surface K. That is, the surface of the lower side member 18 on which the male part 3 or the female part 2 is provided is the contact surface 10d, so that the operator can look at the insertion of the male part 3 and the female part 2 when the male part 3 and the female part 2 are inserted. It is possible to safely perform the insertion work without greatly changing the posture. For example, compared to the case where the contact surfaces 10d and 10d are provided on the hole bottom surface 84 of the female portion 2 and the end surface of the male portion 3 (the other of the short cylindrical members 6), the course forming bodies 1 and 1 are connected to each other. It is easy (at a glance) to know how close it should be, and the insertion work can be performed smoothly. Further, since the receiving member 8 is fixed via the mounting member 17 with the back surface of the lower side member 18 as a reference, it is easy to obtain insertion dimension accuracy and alignment (assembly) accuracy, and manufacture is also easy.

Then, as shown in FIG. 7, the male part 3 (the other insertion part 60 of the short cylindrical member 6) is inserted into the recessed part 80 of the female part 2 to a predetermined depth, and the contact surfaces 10d, 10d. It will be in the insertion state which mutually contact | abutted.
The reference inner peripheral surface 82 of the female part 2 and the reference outer peripheral surface 62 of the male part 3 correspond to each other (positioned), and the connection facing surfaces K and K (course forming bodies 1 and 1) are vertically and horizontally The positional deviation in the direction is restricted (positioning in the vertical and horizontal directions has been performed).
In order to facilitate the explanation of the present invention, the left and right direction is called with the approaching / separating direction (axial direction) of the male part 3 and female part 2 as the front-rear direction. Therefore, the direction of the whole course, the sliding direction, and the left and right direction of the rider do not necessarily match. That is, the posture in use is not limited based on the direction. Moreover, the approach to each other is not limited to the case where both move, but includes the case where one is fixed and the other is approached. In other words, it only needs to be relatively close.

  Then, from the insertion completion state (completed body contact completion state) of FIG. 7, the bolt member 7 inserted through the bolt shaft portion insertion hole 87 of the female portion 2 is moved to the other screw hole portion 67 of the short columnar member 6. By screwing, the insertion completion state is maintained (see FIG. 3).

Here, a connecting through-hole into which a connecting bolt is inserted is provided in each of the connection facing surfaces K and K of the course forming bodies 1 and 1 to be assembled with each other. The connecting through-hole penetrates the protruding piece member fixed to the base frame 10.
And in the insertion completion state, the through hole for connection of one connection facing surface K corresponds to the through hole for connection of the other connection facing surface K (becomes a communication state). The connecting bolts are inserted into both connecting through holes and the nut members are screwed together, thereby fixing the course forming bodies 1 and 1 to each other (bolt / nut coupling).
Further, the jack bolt member 13 is extended so that the lower end portion is brought into contact with the installation surface G, and the wheel 12 is slightly lifted from the installation surface G to prevent the wheel 12 from traveling. Further, the jack bolt member 13 is expanded and contracted to make fine adjustments such as leveling out. And as shown in FIG.1 and FIG.2, it will be in the assembly completion state in which the sliding sport equipment S can drive | work.

  Here, the male-female insertion structure of the male part 3 and the female part 2 described above can be freely changed. That is, the base 5 of the male part 3 and the female part 2 have the same shape and dimensions (consisting of the receiving member 8 that is the same part), and as shown in FIG. 8, the outer peripheral shape of the short columnar member 6 is , With respect to the longitudinal center line J, it has a line-symmetric shape, and the screw hole portions 67, 67 at both ends have the same screw standard (screw type, screw nominal diameter, screw pitch, screw thread shape, screw thread winding direction are the same) ). The bolt members 7 and 7 screwed to the short columnar member 6 have the same screw standard.

For example, in the male part 3 shown in FIG. 4, if the short columnar member 6 is removed (removed) from the receiving member 8 (base part 5) as shown in FIG. 8, the base part 5 is connected to the female part 2. Become.
Then, if a short cylindrical member 6 in a detached state as shown in FIG. 8 is inserted into the female part 2 (receiving member 8) shown in FIG. 5, the female part 2 becomes the base part 5 if screwed with the bolt member 7. The male part 3 is formed in the other course forming body 1.
Therefore, if the short cylindrical member 6 is attached to and detached from the receiving member 8 according to the male and female one part provided on the mating connection facing surface K, the male and female one part provided on the mating connection facing surface K is provided. The male and female other part which can respond to can be formed. That is, the desired course forming bodies 1 and 1 can be aligned with each other without worrying about sex.

Further, the course forming body 1 has a plurality of connection facing surfaces K, K, and the female portion 2 or the male portion 3 is disposed on each connection facing surface K (the receiving member 8 is disposed). In addition, a plurality of other course forming bodies 1 are configured to be capable of regulating positional deviation (positioning in the vertical and horizontal directions) by the male and female insertion structure with respect to one course forming body 1.
For example, as shown in FIG. 2, a total of four other course forming bodies 1 are provided with a female part 2 or a male part 3 for one course forming body 1 so as to be aligned.

Next, another example of the female part 2 and the male part 3 shown in FIG. 9 will be described.
The other example shown in FIG. 9 is different from FIGS. 1 to 8 in that the shape of the recessed portion 80 is different, the reference inner peripheral surface 82 is longer, and the tapered inner peripheral surface 83 (FIGS. 3, 4, and 5). Reference) is omitted. Further, the shape of the outer peripheral surface of the short columnar member 6 is different, the taper guide surface 61 is small, and the reference outer peripheral surface 62 is lengthened. Therefore, the manufacturing is facilitated, and the corresponding area between the reference inner peripheral surface 82 and the reference outer peripheral surface 62 is widened, and the backlash can be reduced. Other configurations and operational effects are the same as those of the above-described embodiment.

  Further, as shown in FIG. 1, the course forming body 1 in which the sliding surface material 11 is attached to the base frame 10 in a concave shape when viewed from the side supports the back surface of the sliding surface material 11 (via the buffer plate material 14). An arc-shaped sliding surface support member 15 is provided. The sliding surface support member 15 and the base frame 10 are connected via a turnbuckle 19 so that the curvature radius R of the surface (sliding surface) of the sliding surface material 11 can be adjusted.

And have.
The upper portion of the sliding surface support member 15 is fixed to the upper portion of the side frame portion 10v, and the lower portion of the sliding surface support member 15 is fixed to the tip portion of the lower frame portion 10w.
Then, one screw portion 19a of the turnbuckle 19 is connected to the upper and lower intermediate portion of the sliding surface support member 15 (member supporting the upper and lower intermediate portion of the sliding surface material 11), and the other screw portion 19b of the turnbuckle 19 is connected. Is connected (attached via a connecting member) to the lower frame portion 10w of the base frame 10.

  By providing the turnbuckle 19, the expansion / contraction deformation (change in the radius of curvature R) of the sliding surface material 11 due to heat, moisture, or the like can be finely adjusted (corrected). For example, as shown in FIG. 11, a plurality of downward-curved concave course forming bodies 1, 1 are assembled adjacent to each other in parallel, and the sliding surface material 11 of another course forming body 1 adjacent to each other is assembled. When a step is generated between the two, the turnbuckle 19 can minimize the step and provide a smooth and safe running surface.

  Further, the shape of the course forming body 1 (the shape, area, posture, and height position of the sliding surface) is free, and the side-viewing quadrantal shape that forms the downward curved concave sliding surface shown in FIG. 1 ( In addition to the square pipe type (Box type, Mini Box type, Manny Pad type, block type, etc.) that forms a rectangular or belt-like water smooth running surface, the side view triangle type that forms an inclined running surface (Quarter pipe type) (Bank type, Bank Large type, Gap type, etc.), rectangular parallelepiped type (Angle Grind Box type, etc.) that forms an inclined sliding surface in a planar view, a substantially T-shaped cross section (Bench type or Table type), upwardly curved convex A dome shape that forms a cylindrical sliding surface, and a cylindrical shape that forms a circular horizontal sliding surface.

Further, the layout of the course Q (sometimes called a floor or a section) composed of a plurality of course forming bodies 1 and 1 is also free.

Angle Grind Box type course formers 1 and 1 are arranged at both ends in the longitudinal direction of the course former 1 respectively. A Hubby Ledge type is installed, and a Manny Pad type course forming body 1 is connected to the middle part in the longitudinal direction. In addition, although not shown, two Quarter pipe type courses are omitted. Spine type in which formations 1 and 1 are connected in a mountain shape, explanation is omitted, but Hip type, R to R type, Bank to Bank type, Flat Bank type, Bank to R type, A Frame Grind Box type, Manual Pad Type, Stair Ramp type, Mini Ramp type, Vertical Ramp type, Wall Ramp type, Wave Ramp type, Pyramid Ramp-θ1 type, Pyramid Ramp-θ2 type, Snake type and the like.
