Description

[Technical Field]

[0001] The present invention relates to an assembly structure for constructing sections that are primarily used for racing or practicing bicycles, skateboards, etc. [Background technology]

[0002] In bicycle racing such as BMX or skateboarding, sections of various shapes are installed individually or in combination, such as banks which are inclined sections, quarter ramps which are quarter curved sections, semi-cylindrical vertical ramps, bowls which are sections hollowed out in the shape of a curved bowl, etc., and for sections that are not permanently installed, prefabricated structures that can be easily assembled are used. Regarding such prefabricated structures, the following configuration is disclosed in Patent Document 1, which will be mentioned later.

[0003] Figure 10 is a side view of the assembly structure disclosed in Patent Document 1, in which 100 is a course formation body, which is a unit for forming an appropriate course. In Figure 10, two course formation bodies 100, 100 are fixed, and one forms a slope course and the other a flat course, as will be described later.

[0004] The course formation structure 100 for a slope course is equipped with a metal base frame 160 that is roughly L-shaped in side view, and a pair of bow-shaped support members 110 (110) are supported in an inclined position by this base frame 160. A sliding surface material 170 is attached to the support members 110 (110) so as to straddle both support members 110 (110). On the other hand, the course formation structure 100 for a flat course is equipped with a roughly cubic base frame 160, and a flat sliding surface material 170 is fixed to the ceiling of the base frame 160.

[0005] A plurality of wheels 180, 180, . . . and a plurality of jack bolt members 190, 190, . . . are attached to the bottom of each of the base frames 160, 160, so that the base frames 160, 160 can be easily moved and fixed.

[0006] These course forming bodies 100, 100 have connecting opposing surfaces K, K that are to be assembled by abutting against each other. A short cylindrical male part 130 is disposed on one of the connecting opposing surfaces K, K, and a female part 150 having a recessed part 140 is disposed on the other, and when the connecting opposing surfaces K, K are brought close to each other and the male part 130 is inserted into the female part 150, in the completed insertion state, positional deviation between the connecting opposing surfaces K, K in the up / down and left / right directions is restricted.

[0007] In such an assembled structure, the course formation bodies 100, 100 can be moved easily and quickly using the wheels 180, 180, ..., and the course formation bodies 100, 100 can be smoothly aligned with each other by inserting the female parts 150 into the male parts 130. In addition, installation can be done safely and easily using the jack bolt members 190, 190, .... Therefore, the layout of the course (section) can be changed safely by a small number of people without the need for construction vehicles such as cranes or skilled techniques.

[0008] However, in such an assembly structure, the sliding surface material 170 is mounted on a pair of parallel-arranged, bow-shaped support members 110 (110), so while it can be easily applied to the quarter ramp-type section mentioned above, it has been difficult to apply it to, for example, the bowl-type section mentioned above.

[0009] Therefore, in the past, to form such a bowl-shaped section, multiple bow-shaped vertical members were arranged and fixed at a predetermined interval, multiple bow-shaped horizontal members were erected and temporarily fixed between adjacent vertical members at predetermined height positions so that they were horizontal to each other, and then both ends of each horizontal member were welded and fixed to the erected vertical members repeatedly, and then face members were fixed to the front side of the horizontal members. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Japanese Patent Application Publication No. 2018-201794 Summary of the Invention [Problem to be solved by the invention]

[0011] However, in such conventional assembled structures, it was necessary to repeatedly erect and temporarily fasten multiple horizontal members at multiple predetermined height positions so that they were horizontal to each other, and then to weld both ends of each horizontal member to the erected vertical members, which required a lot of effort and a long time to complete the assembly.

[0012] The present invention has been made in view of the above circumstances, and provides an assembly structure that can be assembled easily and in a short time even if it is a bowl-shaped section. [Means for solving the problem]

[0013] (1) The assembled structure of the present invention is an assembled structure formed by assembling a plurality of vertical members and a plurality of horizontal members in a grid pattern and fixing surface members of an appropriate shape onto them, characterized in that the vertical members have a strip-shaped first body and a plurality of first mating recesses provided at an appropriate distance in the longitudinal direction of the first body, and the horizontal members have a strip-shaped second body and a plurality of second mating recesses provided at an appropriate distance in the longitudinal direction of the second body, and are configured so that the vertical members and horizontal members are assembled by mating the first mating recesses with the second mating recesses.

[0014] The assembled structure of the present invention is constructed by assembling a plurality of vertical members and a plurality of horizontal members in a grid pattern, and fixing appropriately shaped surface members onto the grid. Here, the vertical members have a strip-shaped first main body, and this first main body has a plurality of first fitting recesses provided at appropriate distances along its length. Similarly, the horizontal members have a strip-shaped second main body, and this second main body has a plurality of second fitting recesses provided at appropriate distances along its length. The assembled structure is configured so that the vertical members and horizontal members are assembled by fitting the first fitting recesses and the second fitting recesses together.

[0015] As mentioned above, in the prior art, multiple vertical members were arranged and fixed at a predetermined interval, and multiple horizontal members were each temporarily erected between adjacent vertical members at a predetermined number of height positions so that they were horizontal to each other, and then both ends of each horizontal member were welded and fixed to the erected vertical members repeatedly. However, in the assembled structure of the present invention, the vertical members and horizontal members are assembled by engaging the first mating recess provided in the first main body that constitutes the vertical member with the second mating recess provided in the second main body that constitutes the horizontal member, so that the horizontal member can be arranged at a predetermined height position of the vertical member with a single touch.

[0016] In addition, the vertical members and horizontal members can be formed into any desired shape, so sections of various shapes, including bowl-shaped ones, can be assembled easily and quickly. Here, the vertical members and horizontal members are assembled by fitting the first fitting recesses provided on the first body with the second fitting recesses provided on the second body, so that the horizontal members are prevented from shifting either vertically or horizontally after fitting, so the task of assembling the vertical members and horizontal members into a lattice pattern can be carried out quickly and with high precision.

[0017] (2) The assembly structure according to the present invention is characterized in that the first body and the second body are both formed in an arch shape, the first mating recess is provided on the inside of the arch of the first body, and the second mating recess is provided on the outside of the arch of the second body.

[0018] In the assembled structure of the present invention, the first and second bodies are both formed in an arched shape, with the first mating recess on the inside of the arch of the first body and the second mating recess on the outside of the arch of the second body, so that a bowl-shaped framework can be formed simply by assembling the vertical members and horizontal members in a lattice pattern. Therefore, even bowl-shaped sections can be assembled easily and in a short time.

[0019] (3) The assembly structure according to the present invention is characterized in that one end of the first body has a flat portion on the outer side of the arch, and the vertical member is arranged so that one end of the first body is on the lower side in the height direction.

[0020] In the assembled structure of the present invention, a flat portion is provided on one end of the first main body, on the outer side of the arch. The vertical members are arranged such that one end of the first main body is positioned lower in the height direction, so that the flat portion of the first main body abuts against the installation surface of the assembled structure. Therefore, the assembled structure installed on the installation surface is highly stable because the flat portion of the first main body constituting the vertical member abuts against the installation surface. When the assembled structure is applied to bicycle racing or the like, the safety of the race can be ensured.

[0021] (4) The assembled structure according to the present invention is characterized by comprising a plurality of supporting frame members for supporting the vertical members in an appropriate posture.

[0022] The assembled structure of the present invention includes a plurality of supporting frame members that support the vertical members in an appropriate position. That is, a plurality of vertical members and a plurality of horizontal members are assembled in a lattice pattern, and the vertical members are supported in an appropriate position by the plurality of supporting frame members. This allows the vertical members and horizontal members assembled in a lattice pattern to be easily and quickly positioned in an appropriate position.

[0023] (5) The assembly structure according to the present invention is characterized in that each of the supporting frame members has a plurality of arm sections that support different height positions of the vertical members, and a first connecting section that connects the corresponding arm sections is provided on the outer side of the arch of the first body at the position where each arm section supports, and each arm section has a second connecting section that connects to the corresponding first connecting section.

[0024] In the assembled structure of the present invention, each of the aforementioned supporting frame members is provided with a plurality of arm portions that support the vertical members at different height positions, so that each of the vertical members and horizontal members assembled in a lattice pattern can be supported in an appropriate posture.

[0025] Furthermore, a plurality of first connecting portions are provided on the outer side of the arch of the first body at positions where the arms are supported, connecting the corresponding arms. Meanwhile, each arm is provided with a second connecting portion that connects to the corresponding first connecting portion. This allows the vertical members to be easily and quickly connected to the support member in an appropriate position by connecting each first connecting portion to the corresponding second connecting portion. Therefore, the vertical members and horizontal members assembled in a lattice pattern can be easily and quickly held and fixed in an appropriate position.

[0026] (6) The assembly structure according to the present invention is characterized in that the first connecting portion and the corresponding second connecting portion are formed so as to be able to be superimposed on each other, and each of the first connecting portion and the second connecting portion has a through hole that communicates with the first connecting portion and the second connecting portion when the first connecting portion and the second connecting portion are superimposed on each other.

[0027] In the assembly structure of the present invention, the first connecting portion and the corresponding second connecting portion are molded so that they can be overlapped with each other, and each of the first connecting portion and the second connecting portion has a through hole that communicates with the first connecting portion and the second connecting portion when they are overlapped. Therefore, by inserting a bolt or the like into both of the communicating through holes, the first connecting portion and the second connecting portion can be easily and quickly connected.

[0028] On the other hand, the first connecting portion and the corresponding second connecting portion are formed, for example, in a tongue shape so that they can be overlapped with each other, and this allows them to be easily overlapped with each other.

[0029] The first connecting portion and the corresponding second connecting portion may be provided with meshing projections and recesses at their opposing portions, thereby further strengthening the connection between the first connecting portion and the second connecting portion.

[0031] The assembly structure according to the present invention will be described in detail with reference to the drawings. The assembly structure described in this embodiment is an example for explaining the gist of the present invention, and it goes without saying that the present invention includes modifications and alterations within the scope of the gist of the present invention.

[0032] Fig. 1 is an external perspective view showing an assembly structure according to the present invention, in which 7 denotes a curved panel. Meanwhile, Fig. 2 is a perspective view showing the configuration of the assembly structure S before the panel 7 shown in Fig. 1 is attached, in which 4 denotes a support member that supports the panel 7 shown in Fig. 1. Furthermore, Fig. 3 is a perspective view showing the configuration of the assembly structure S before the support member 4 shown in Fig. 2 is attached, and shows the skeleton of the assembly structure S. The assembly structure S according to the present invention will be described in detail using Figs. 1 to 3.

[0033] As shown in Figure 3, the assembly structure S of the present invention is composed of a plurality of arched vertical members 1, 1, ... arranged radially, and a plurality of arched horizontal members 2, 2, ... arranged at appropriate distances in the longitudinal direction of the vertical members 1, 1, ...

[0034] FIG. 4 is a perspective view of the vertical member 1 shown in FIG. As shown in Figure 4, the vertical member 1 has a first body 11 formed by shaping a strip of plate material into a bow shape, and the vertical member 1 is designed to be used with the width direction of the first body 11 aligned vertically. At one end of the first body 11, the depth dimension from the outside to the inside of the bow decreases toward the end, and a flat portion 12 is provided on the outer side of the bow, so that the end of the first body 11 is shaped like a sharp sword.

[0035] On the inside of the arched shape of the first main body 11, a plurality of first fitting recesses 14, 14, ... for fitting the cross member 2 (see FIG. 3) are provided at predetermined distances in the height direction of the first main body 11 and in an orientation approximately parallel to the flat portion 12. On the other hand, on predetermined positions on the outside of the arched shape of the first main body 11, a plurality of tongue-shaped (three in FIG. 4) first connecting portions 15, 15, 15 for connecting and fixing to a carrying frame member 6 (see FIG. 2) described below are respectively protruded, and each of the first connecting portions 15, 15, 15 has a through hole 16, 16, 16 for passing a bolt therethrough.

[0036] FIG. 5 is a perspective view of the cross member 2 shown in FIG. As shown in Figure 5, each of the horizontal members 2, 2, ... is made by shaping a strip of plate material into an arch shape and includes second bodies 21, 21, ... of different lengths, and each horizontal member 2, 2, ... is used in an orientation where the width direction of the second bodies 21, 21, ... is approximately parallel to the ground surface of the assembled structure. Each of the second bodies 21, 21, ... has the same curvature as each other, but is shaped to a length that corresponds to the height position of the vertical member 1 to which it is attached.

[0037] In addition, on the outer side of the arch shape of each second main body 21, 21, ..., a plurality of second mating recesses 24, 24, ... for mating with the first mating recess 14 of the vertical member 1 described above are provided at a predetermined distance in the longitudinal direction of the second main body 21, 21, ...

[0038] Figure 6 is a partially enlarged perspective view showing the state of the vertical member 1 and the horizontal member 2 before assembly, and will be used to describe in detail the first fitting recess 14 and the second fitting recess 24. In this figure, parts corresponding to those shown in Figures 4 and 5 are assigned the same numbers.

[0039] As shown in Figure 6, the first fitting recess 14 is arranged in a generally rectangular shape at an angle to the central axis of the first main body 11, extending from the inside of the arch of the first main body 11 to a position near the outside, and the portion facing the mouth of the first fitting recess 14 on the inside of the arch of the first main body 11, which is located on the other end side of the first main body 11, has a rounded tip.

[0040] On the other hand, the second fitting recess 24 is provided in a rectangular shape extending from the outer side of the arch of the second main body 21 to around the central axis of the second main body 21 in a radial manner from the center of the arch of the second main body 21.

[0041] To assemble the vertical member 1 having such a first body 11 and first mating recess 14 and the horizontal member 2 having the second body 21 and second mating recess 24, as shown in Figure 6, the vertically arranged first body 11 and the horizontally arranged second body 21 are aligned so that the first mating recess 14 and the second mating recess 24 face each other, and then, as shown in Figure 7, the second mating recess 24 and the second body 21 are inserted and fitted into the first mating recess 14, and the first mating recess 14 and the first body 11 are inserted and fitted into the second mating recess 24.

[0042] In this way, by fitting the second body 21 into the first fitting recess 14, the first body 11 and the second body 21 are restricted from shifting relative to each other in the vertical direction. Similarly, by fitting the first body 11 into the second fitting recess 24, the first body 11 and the second body 21 are restricted from shifting relative to each other in the horizontal direction.

[0043] On the other hand, as mentioned above, the tip of the part facing the mouth of the first mating recess 14 on the inside of the arch of the first main body 11, which is located on the other end side of the first main body 11, is rounded, so that it is possible to prevent injury to the fingers of the worker when inserting and mating the second mating recess 24 and the second main body 21 into the first mating recess 14 as mentioned above.

[0044] The depth dimension of the first body 11, the width dimension of the second body 21, and the depth dimensions of the first mating recess 14 and the second mating recess 24 are set to values ​​such that when the second mating recess 24 and the second body 21 are mated into the first mating recess 14, the inner arch of the second body 21 does not protrude outward from the inner arch of the first body 11.

[0045] FIG. 8 is a plan view of the support member 4 shown in FIG. As shown in Fig. 8, the support member 4 has a strip-like shape in a plan view and a bow-like shape in a side view, and the length of the support member 4 is approximately the same as the length of the first main body 11 constituting the vertical member 1 described above. The support member 4 is also bent to have a curvature that corresponds to the curvature of the inside of the bow-like shape of the first main body 11. Meanwhile, the support member 4 has a plurality of screw holes 43, 43, ... for fixing the face member 7 shown in Fig. 1 opened at appropriate intervals in the longitudinal direction.

[0046] In such an assembled structure S, as shown in Fig. 3, a plurality of vertical members 1, 1, ... and a plurality of horizontal members 2, 2, ... are assembled in a curved lattice shape, and then, as shown in Fig. 2, each of the vertical members 1, 1, ... and each of the horizontal members 2, 2, ... are supported by one or more (three in Fig. 2) supporting frame members 6, 6, 6 so that the other end of the vertical members 1, 1, ... is at a predetermined height position. The assembly order of the vertical members 1, 1, ... and the horizontal members 2, 2, ... will be described later.

[0047] Next, as shown in Fig. 2, the support members 4 are fixed to the inside of the arched shape of the first main bodies 11 constituting each of the vertical members 1 so that the inside of the first main bodies 11 abuts against the approximate center in the width direction of the support members 4. The support members 4 can be fixed to the vertical members 1 by any appropriate method, such as welding or bolt and nut fastening.

[0048] Then, as shown in Figure 1, the surface material 7 formed in a curved bowl shape is placed on each of the support members 4, 4, ..., and the surface material 7 is fixed to the support members 4, 4, ... by threading multiple screws that have passed through this surface material 7 into each of the screw holes 43, 43, ... (see Figure 8) opened in the support members 4, 4, ...

[0049] Although FIG. 1 shows a case where a single piece of panel 7 is used, the present invention is not limited to this, and it goes without saying that a plurality of panel members each having a triangular shape when viewed from the front can be used.

[0050] Here, the supporting frame member 6 will be described. As shown in Figure 2, the supporting frame member 6 comprises an L-shaped frame body 60 with an upright tip, which has a reclining bottom 65, a first arm 61 erected at the base end of the bottom 65, and a third arm 63 erected at the tip of the bottom 65. A brace 66 is interposed between the first arm 61 and the bottom 65 of the frame body 60, and a second arm 62 of an appropriate length is erected at an appropriate angle midway along the length of the brace 66. The height positions of the tips of the first arm 61 to third arm 63 are such that the tip of the first arm 61 is highest, followed by the second arm 62 and the third arm 63 in that order.

[0051] Tongue-shaped second connecting portions 67, 67, 67 protrude from the tips of the first arm portion 61 to the third arm portion 63, respectively, to correspond to the first connecting portions 15, 15, 15 of the vertical member 1 described above, and each second connecting portion 67, 67, 67 is provided with a through hole 68, 68, 68 through which a bolt can be passed.

[0052] As shown in Figure 2, the carrying frame members 6,6 are positioned on the vertical members 1,1 arranged on both sides of the vertical members 1,1,... and horizontal members 2,2,... assembled in a roughly fan lattice shape, so that the first connecting portions 15,15,15,15,15,15 of the vertical members 1,1 and the second connecting portions 67,67,67,67,67,67,67 of the carrying frame members 6,6 overlap each other, and bolts (not shown) are passed through the through holes 16,16,16, 68,68,68 of the paired first connecting portions 15,15,15,15,15,15 and second connecting portions 67,67,67,67,67,67, and nuts threaded onto each bolt are tightened to fix the vertical members 1,1 and the carrying frame members 6,6 to each other.

[0053] In the same manner as above, another supporting frame member 6 is fixed to the vertical member 1 arranged near the center of the vertical members 1, 1, . . . and horizontal members 2, 2, .

[0054] As a result, the vertical members 1, 1, ... and horizontal members 2, 2, ... assembled in a roughly fan lattice shape are supported in a predetermined position by the supporting frame members 6, 6, 6. At this time, as described above, since the flat portions 12, 12, ... are provided on one end of the first main bodies 11, 11, ... constituting the vertical members 1, 1, ..., on the outside of the arch shape, the flat portions 12, 12, ... come into contact with the installation surface, providing high stability, and when the assembled structure S is applied to bicycle competitions, etc., the safety of the competition can be ensured.

[0055] Next, an example of the procedure for assembling the vertical members 1, 1, ... and the horizontal members 2, 2, ... will be described. In this example, a case will be described in which seven vertical members 1, 1, ... and four horizontal members 2, 2, ... are used.

[0056] 9 is an explanatory diagram illustrating an example of the assembly order of a plurality of vertical members 1, 1, ... and a plurality of horizontal members 2, 2, .... In the drawing, the circled numbers indicate the assembly order.

[0057] As shown in Figure 9, the vertical members 1, 1 to be positioned at both ends are arranged in predetermined radial positions, and the horizontal member 2 with the shortest length dimension is aligned so that the first fitting recess arranged at the bottom of both vertical members 1, 1 faces the two second fitting recesses arranged on both sides of the horizontal member 2.Then, the second fitting recess and the second main body 21 of the horizontal member 2 are inserted and fitted into the first fitting recesses of both vertical members 1, 1, and the first fitting recess and the first main body 11 are inserted and fitted into the second fitting recess, and both vertical members 1, 1 and the horizontal member 2 are fixed to each other by welding or screwing, etc.

[0058] Next, the remaining vertical members 1,1, ... are arranged radially between the two fixed vertical members 1,1, and as before, they are aligned so that each first mating recess arranged at the bottom of each vertical member 1,1, ... faces each of the remaining second mating recesses of the horizontal member 2, and then the second mating recess and second main body 21 of the horizontal member 2 are inserted and mated into the first mating recess of each vertical member 1,1, ..., and the first mating recess and first main body 11 are inserted and mated into the second mating recess, thereby fixing the remaining vertical members 1,1, ... and the horizontal member 2 to each other.

[0059] Then, the next short horizontal member 2 is aligned so that the first fitting recesses arranged in the second row of each of the vertical members 1, 1, ... face the second fitting recesses arranged in the horizontal member 2, and then the second fitting recesses and second main body 21 of the horizontal member 2 are inserted and fitted into the first fitting recesses of each of the vertical members 1, 1, ..., and the first fitting recesses and first main body 11 of each of the vertical members 1, 1, ... are inserted and fitted into the second fitting recesses, thereby fixing each of the vertical members 1, 1, ... and the horizontal member 2 to one another. By performing the same operation for the remaining horizontal members 2, 2, each of the vertical members 1, 1, ... and each of the horizontal members 2, 2, ... are assembled.

[0060] In such an assembled structure S, a plurality of vertical members 1, 1, ... each having an arch-shaped first body 11 is provided with a plurality of first fitting recesses, and a plurality of horizontal members 2, 2, ... each having an arch-shaped second body 21 is also provided with a plurality of second fitting recesses, and by fitting the corresponding first fitting recesses into the corresponding second fitting recesses, the vertical members 1, 1, ... and the horizontal members 2, 2, ... can be assembled easily, quickly, and with high precision into a bowl-shaped lattice pattern. Therefore, even bowl-shaped sections can be assembled easily and quickly.

[0061] In this embodiment, the second connecting portions 67, 67, 67 are respectively protruded from the tips of the first arm portion 61 to the third arm portion 63, but the present invention is not limited to this, and it goes without saying that the second connecting portions 67, 67, 67 may be provided at appropriate positions in the longitudinal direction of the first arm portion 61 to the third arm portion 63.
