Description

Technical Field

[0001] The present invention mainly relates to an assembled structure for constituting sections used for competitions or practices such as bicycles or skateboards.

Background Art

[0002] In bicycle competitions such as BMX or skateboard competitions, various shapes of sections are provided singly or in combination, such as a bank which is an inclined section, a quarter ramp which is a 1 / 4 curved surface section, a vertical ramp which is a semi-cylindrical shape, and a bowl which is a section hollowed out in a bowl shape. For sections that are not permanent, an assembled structure that can be easily assembled is used. Regarding such an assembled structure, the following configuration is disclosed in Patent Document 1 described later.

[0003] FIG. 10 is a side view of the assembled structure disclosed in Patent Document 1. In the figure, reference numeral 100 denotes a course former which is a unit for forming an appropriate course. In FIG. 10, two course formers 100, 100 are fixed. As will be described later, one forms an inclined course and the other forms a flat course.

[0004] The course former 100 related to the inclined course includes a metal base frame 160 having a substantially L-shaped side view, and a pair of arcuate support members 110(110) are supported in an inclined posture by the base frame 160. A sliding surface material 170 is attached on the support members 110(110) so as to straddle both support members 110(110). On the other hand, the course former 100 related to the flat course includes a substantially 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 bottoms of both base frames 160, 160, respectively, so that the movement and fixation of the base frames 160, 160 can be facilitated.

[0006] Such course-forming bodies 100, 100 have connecting opposing surfaces K, K that are to be assembled by contacting each other. One of the connecting opposing surfaces K, K is provided with a short cylindrical male part 130, and the other is provided with a female part 150 having a recessed part 140. 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, the positional displacement of the connecting opposing surfaces K, K in the vertical and horizontal directions is restricted.

[0007] In such an assembled structure, the course forming bodies 100, 100 can be moved easily and quickly by wheels 180, 180, ... and the course forming bodies 100, 100 can be smoothly aligned with each other by inserting the female part 150 and the male part 130. Furthermore, they can be installed safely and easily by jack bolt members 190, 190, ... Therefore, the layout of the course (section) can be changed safely by a small number of people, even without construction vehicles such as cranes or skilled personnel.

[0008] However, in such an assembled structure, the sliding surface material 170 is installed on a pair of parallel-arranged arch-shaped support members 110 (110), so it can be easily applied to the quarter-ramp type section described above, but it was difficult to apply to the bowl-shaped section described above, for example.

[0009] Therefore, conventionally, to form such a bowl-shaped section, multiple arch-shaped vertical members were arranged and fixed at predetermined intervals, and multiple arch-shaped horizontal members were temporarily erected between adjacent vertical members at predetermined height positions so that they remained horizontal to each other. Then, the ends of each horizontal member were welded and fixed to the erected vertical members, and this process was repeated. Finally, face panels were fixed to the front side of these sections. [Prior art documents] [Patent Documents]

[0010] [Patent Document 1] Japanese Patent Publication No. 2018-201794 [Overview of the project] [Problems that the invention aims to solve]

[0011] However, in such conventional prefabricated structures, multiple horizontal members had to be temporarily erected and fixed at predetermined height positions so that they remained horizontal to each other, and then both ends of each horizontal member had to be welded and fixed to the erected vertical members. This process was repeated, requiring a great deal of effort and time to complete.

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

[0013] (1) The assembled structure according to the present invention is an assembled structure comprising a plurality of vertical members and a plurality of horizontal members assembled in a grid shape, and a surface material of an appropriate shape fixed thereon, wherein the vertical members comprise a strip-shaped first body and a plurality of first fitting recesses provided at appropriate distances in the longitudinal direction of the first body, and the horizontal members comprise a strip-shaped second body and a plurality of second fitting recesses provided at appropriate distances in the longitudinal direction of the second body, and the vertical members and horizontal members are assembled by fitting the first fitting recesses and the second fitting recesses together. Furthermore, the assembled structure according to the present invention is characterized in that both the first body and the second body are formed in an arch shape, the first fitting recess is provided on the inside of the arch shape of the first body, and the second fitting recess is provided on the outside of the arch shape of the second body. Moreover, the assembled structure according to the present invention is characterized in that, after assembling the vertical members and horizontal members in a lattice shape by fitting the first fitting recess and the second fitting recess together, a strip-shaped support member that supports the surface material is fixed to the inside of the arch shape of each first body.

[0014] In the assembled structure of the present invention, a plurality of vertical members and a plurality of horizontal members are assembled in a grid pattern, and surface members of an appropriate shape are fixed on top of them. Here, the vertical members are provided with a strip-shaped first body, and a plurality of first fitting recesses are provided on this first body at appropriate distances along its longitudinal direction. Similarly, the horizontal members are provided with a strip-shaped second body, and a plurality of second fitting recesses are provided on this second body at appropriate distances along its longitudinal direction. The assembled structure is configured such 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 conventional technology, multiple vertical members are arranged and fixed at predetermined intervals, and multiple horizontal members are erected and temporarily fixed between adjacent vertical members at predetermined height positions so that they maintain a horizontal position relative to each other. Then, the ends of each horizontal member are welded and fixed to the erected vertical members, and this process is repeated. However, in the assembled structure according to the present invention, the vertical members and horizontal members are assembled by fitting together a first fitting recess provided on the first main body constituting the vertical member and a second fitting recess provided on the second main body constituting the horizontal member. Therefore, the horizontal members can be positioned at a predetermined height position of the vertical members with a single touch.

[0016] In addition, these vertical and horizontal members can be molded into appropriate shapes, and therefore, even sections of various shapes, including bowl-shaped sections, can be assembled easily and quickly. Here, the vertical and horizontal members are assembled by fitting together the first fitting recess provided in the first body and the second fitting recess provided in the second body. Since the horizontal members are prevented from shifting in either the vertical or horizontal direction after fitting, the assembly of the vertical and horizontal members in a grid pattern can be carried out quickly and with high precision. Furthermore, in the assembled structure of the present invention, both the first and second main bodies described above are formed in an arch shape, and the first fitting recess is provided on the inside of the arch shape of the first main body, and the second fitting recess is provided on the outside of the arch shape of the second main body. Therefore, a bowl-shaped skeleton is formed simply by assembling the vertical members and horizontal members in a lattice pattern. Consequently, even a bowl-shaped section can be assembled easily and quickly. Moreover, in the assembled structure of the present invention, after assembling the vertical members and horizontal members in a lattice pattern by fitting the first fitting recess and the second fitting recess together, a strip-shaped support member that supports the surface material is fixed to the inside of the arch shape of each first main body.

[0017] (2) The assembled structure according to the present invention is Each of the support members has multiple screw holes for fixing the surface material. It is characterized by the following:

[0018] In the assembled structure of the present invention, as described above Each support member has multiple screw holes for fixing the aforementioned surface material. .

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

[0020] In the assembled structure of the present invention, at one end of the first main body described above, a flat portion is provided on the arcuate outer side. And since the vertical member is arranged with one end of the first main body on the lower side in the height direction, the flat portion of the first main body abuts on the installation surface of the assembled structure. Therefore, the assembled structure installed on the installation surface has high stability because the flat portion of the first main body constituting the vertical member abuts on the installation surface, and when the assembled structure is applied to bicycle racing or the like, the safety of the racing can be ensured.

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

[0022] In the assembled structure of the present invention, a plurality of supporting frame members that support the above-described vertical member in an appropriate posture are provided. That is, a plurality of vertical members and a plurality of horizontal members are assembled in a grid pattern, and the vertical members are supported in an appropriate posture by the plurality of supporting frame members. Thereby, each vertical member and each horizontal member assembled in a grid pattern can be placed in an appropriate posture easily and in a short time.

[0023] (5) The assembled structure according to the present invention is characterized in that each of the supporting frame members includes a plurality of arm portions that respectively support different height positions of the vertical member, and on the arcuate outer side of the first main body at the positions supported by the respective arm portions, first connecting portions for connecting the corresponding arm portions are provided, and each arm portion is provided with a second connecting portion for connecting to the corresponding first connecting portion.

[0024] In the assembled structure of the present invention, since each of the above-described supporting frame members includes a plurality of arm portions that respectively support different height positions of the vertical member, each vertical member and each horizontal member assembled in a grid pattern can be supported in an appropriate posture.

[0025] Also, on the outer side of the arcuate shape of the first main body, at the positions supported by each arm portion, a plurality of first connecting portions for connecting the corresponding arm portions are provided respectively. On the other hand, each arm portion is provided with a second connecting portion for connecting to the corresponding first connecting portion. By connecting each first connecting portion and the corresponding second connecting portion to each other, the vertical member can be easily and quickly connected to the supporting member in an appropriate posture. Therefore, each vertical member and each horizontal member assembled in a lattice shape can be easily and quickly held and fixed in an appropriate posture.

[0026] (6) In the assembled structure according to the present invention, the first connecting portion and the corresponding second connecting portion are formed so as to be able to overlap each other, and through holes that communicate with each other when both are overlapped are provided in both the first connecting portion and the second connecting portion respectively.

[0027] In the assembled structure of the present invention, the first connecting portion and the corresponding second connecting portion described above are formed so as to be able to overlap each other, and through holes that communicate with each other when both are overlapped are provided in both the first connecting portion and the second connecting portion respectively. Therefore, by inserting a bolt or the like through the two 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 as to be able to overlap each other, whereby the two can be easily overlapped.

[0029] In addition, concavo-convex portions that mesh with each other may be provided at portions where the first connecting portion and the corresponding second connecting portion face each other. Thereby, the connection between the first connecting portion and the second connecting portion can be made stronger.

[Figure 10] This is a side view of the assembled structure disclosed in Patent Document 1. [Modes for carrying out the invention]

[0031] The assembled structure according to the present invention will be described in detail with reference to the drawings. It should be noted that the assembly structure described in this embodiment is merely an example illustrating the spirit of the present invention, and the present invention may include modifications and alterations that do not depart from its spirit.

[0032] Figure 1 is an external perspective view showing the assembled structure according to the present invention, where 7 is a bowl-shaped surface material. On the other hand, Figure 2 is a perspective view showing the configuration of the assembled structure S before the surface material 7 shown in Figure 1 is attached, where 4 is a support member that supports the surface material 7 shown in Figure 1. Furthermore, Figure 3 is a perspective view showing the configuration of the assembled structure S before the support member 4 shown in Figure 2 is attached, showing the skeleton of the assembled structure S. The assembled structure S according to the present invention will be described in detail using these Figures 1 to 3.

[0033] As shown in Figure 3, the assembled structure S according to the present invention is composed of a plurality of arch-shaped vertical members 1,1,... arranged radially, and a plurality of arch-shaped horizontal members 2,2,... arranged at appropriate distances from the vertical members 1,1,... in the longitudinal direction.

[0034] Figure 4 is a perspective view of the vertical member 1 shown in Figure 3. As shown in Figure 4, the vertical member 1 comprises a first body 11 formed by shaping a strip of sheet metal into an arc shape, and the vertical member 1 is used in a position where the width direction of the first body 11 is vertical. At one end of the first body 11, a flat portion 12 is provided on the outer side of the arc shape, with the depth dimension from the outside to the inside of the arc shape decreasing towards the end, and the first body 11 has a sharp, knife-like shape at this end.

[0035] On the inside of the arched shape of the first body 11, a plurality of first fitting recesses 14, 14, ... for fitting the horizontal member 2 (see Figure 3) are provided at a predetermined distance in the height direction of the first body 11 and in a position substantially parallel to the flat portion 12. On the other hand, at predetermined positions on the outside of the arched shape of the first body 11, a plurality of tongue-shaped first connecting portions 15, 15, 15 (three in Figure 4) for connecting and fixing to the carrying frame member 6 (see Figure 2), which will be described later, are provided, and through holes 16, 16, 16 for passing bolts through each first connecting portion 15, 15, 15.

[0036] Figure 5 is a perspective view of the horizontal member 2 shown in Figure 3. As shown in Figure 5, each horizontal member 2,2,... is formed by shaping a strip of sheet metal into an arc shape and comprises second bodies 21,21,... of different lengths. Each horizontal member 2,2,... is used in a position where the width direction of the second bodies 21,21,... is approximately parallel to the ground surface of the assembled structure. Each second body 21,21,... has the same curvature, while being shaped to a length corresponding to the height position of the vertical member 1 on which it is installed.

[0037] Furthermore, on the outer surface of each second body 21, 21, ..., there are multiple second fitting recesses 24, 24, ... provided at predetermined distances in the longitudinal direction of the second body 21, 21, ... for fitting into the first fitting recess 14 of the vertical member 1 mentioned above.

[0038] Figure 6 is a partially enlarged perspective view showing the state of the vertical member 1 and horizontal member 2 before assembly. The first fitting recess 14 and the second fitting recess 24 described above will be explained in detail using Figure 6. Note that the parts in this figure that correspond to the parts shown in Figures 4 and 5 are numbered the same way.

[0039] As shown in Figure 6, the first fitting recess 14 is provided in a substantially rectangular shape, positioned obliquely to the central axis of the first body 11, extending from the inner side of the arched shape of the first body 11 to a position near the outer side. The portion of the first fitting recess 14 facing the opening on the inner side of the arched shape of the first body 11, and located on the other end side of the first body 11, has its tip rounded.

[0040] On the other hand, the second fitting recess 24 is provided in a rectangular shape extending from the outer edge of the second body 21 to the central axis of the second body 21, with the recess radiating outwards from the center of the second body 21's arch shape.

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

[0042] By fitting the second body 21 into the first fitting recess 14 in this manner, the vertical displacement of the first body 11 and the second body 21 relative to each other is restricted. Similarly, by fitting the first body 11 into the second fitting recess 24, the lateral displacement of the first body 11 and the second body 21 relative to each other is restricted.

[0043] On the other hand, as mentioned above, the tip of the part of the first body 11 that faces the opening of the bow-shaped inner first fitting recess 14 and is located on the other end of the first body 11 is rounded, so as mentioned above, it is possible to prevent injury to the fingers of the worker when inserting and fitting the second fitting recess 24 and the second body 21 into the first fitting recess 14.

[0044] Furthermore, the depth dimension of the first body 11, the width dimension of the second body 21, and the depth dimensions of the first fitting recess 14 and the second fitting recess 24 are set such that when the second fitting recess 24 and the second body 21 are fitted into the first fitting recess 14, the arched inner surface of the second body 21 does not protrude outward from the arched inner surface of the first body 11.

[0045] Figure 8 is a plan view of the support member 4 shown in Figure 2. As shown in Figure 8, the support member 4 has a strip-like shape in plan view and an arched shape in side view, and the length of the support member 4 is approximately the same as the length of the first main body 11 that constitutes the vertical member 1 described above. Furthermore, the support member 4 is bent to match the curvature of the arched inner surface of the first main body 11. On the other hand, the support member 4 has a plurality of screw holes 43, 43, ... for fixing the facing material 7 shown in Figure 1, which are provided at appropriate intervals along its longitudinal direction.

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

[0047] Next, as shown in Figure 2, support members 4,4,... are fixed to the inside of the arched first bodies 11,11,... that constitute each vertical member 1,1,... so that the inside of the first bodies 11,11,... abuts against the support members 4,4,... at approximately the center in the width direction of the support members 4,4,.... The support members 4,4,... can be fixed to the vertical members 1,1,... by welding, bolts and nuts, or other appropriate methods.

[0048] Then, as shown in Figure 1, the bowl-shaped facing material 7 is placed on each of the support members 4,4,... and the facing material 7 is fixed to the support members 4,4,... by screwing multiple screws that pass through the facing material 7 into the screw holes 43,43,... (see Figure 8) provided in the support members 4,4,....

[0049] Although Figure 1 shows the case where a single, integrated surface material 7 is used, the present invention is not limited to this, and it goes without saying that multiple surface materials with a triangular shape in front view can be used.

[0050] Now, let's describe the support frame member 6. As shown in Figure 2, the support frame member 6 comprises an L-shaped frame body 60 with an upright tip, the frame body 60 having a horizontally positioned bottom 65, a first arm portion 61 erected at the base end of the bottom 65, and a third arm portion 63 erected at the tip of the bottom 65. A brace portion 66 is interposed between the first arm portion 61 and the bottom 65 of the frame body 60, and a second arm portion 62 of appropriate length is erected at an appropriate angle at an intermediate position in the longitudinal direction of the brace portion 66. The height positions of the tips of these first arm portion 61 to third arm portion 63 are such that the tip of the first arm portion 61 is the highest, followed by the second arm portion 62 and then the third arm portion 63, in descending order.

[0051] At the tips of the first arm section 61 to the third arm section 63, tongue-shaped second connecting sections 67, 67, 67 are provided to protrude in accordance with the first connecting sections 15, 15, 15 of the aforementioned vertical member 1, and through holes 68, 68, 68 are provided in each of the second connecting sections 67, 67, 67 for passing bolts through.

[0052] Then, as shown in Figure 2, the vertical members 1,1,... and horizontal members 2,2,... are assembled in a roughly fan-shaped grid, and the supporting frame members 6,6 are positioned on both sides of the vertical members 1,1,... so that the first connecting parts 15,15,15,15,15 of the vertical members 1,1 and the second connecting parts 67,67,67,67,67 of the supporting frame members 6,6 are aligned so that they overlap. Bolts (not shown) are passed through the through holes 16,16,16, 68,68,68 of the paired first connecting parts 15,15,15,15,15 and second connecting parts 67,67,67,67,67,67, and nuts are screwed onto each bolt to secure the vertical members 1,1 and the supporting frame members 6,6 to each other.

[0053] Furthermore, in the same manner as before, other support frame members 6 are fixed to the vertical members 1, which are positioned near the center of the vertical members 1,1,... and horizontal members 2,2,... assembled in a roughly fan-shaped grid.

[0054] As a result, the vertical members 1,1,... and horizontal members 2,2,... assembled in a roughly fan-shaped grid are supported in a predetermined position by the supporting frame members 6,6,6. At this time, as described above, flat parts 12,12,... are provided on the outer side of the arc shape at one end of the first main body 11,11,... that constitutes the vertical members 1,1,..., so that each flat part 12,12,... contacts the installation surface, providing high stability, and when the assembled structure S is applied to cycling competitions, the safety of the competition can be ensured.

[0055] Next, we will explain an example of the assembly procedure for the vertical members 1,1,... and horizontal members 2,2,... mentioned above. In this example, we will explain the case where seven vertical members 1,1,... and four horizontal members 2,2,... are used.

[0056] Figure 9 is an explanatory diagram illustrating an example of the assembly order of multiple vertical members 1,1,... and multiple horizontal members 2,2,.... The circled numbers in the figure indicate the assembly order.

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

[0058] Next, the remaining vertical members 1,1,... are arranged radially between the two fixed vertical members 1,1. As before, the first fitting recesses located at the bottom of each vertical member 1,1,... are aligned with the remaining second fitting recesses of the horizontal member 2. Then, the second fitting recesses and second body 21 of the horizontal member 2 are inserted and fitted into the first fitting recesses of each vertical member 1,1,..., and the first fitting recesses and first body 11 are inserted and fitted into the second fitting recesses, thereby fixing the remaining vertical members 1,1,... and the horizontal member 2 to each other.

[0059] Next, the short horizontal member 2 is positioned so that the first fitting recesses located on the second row of each vertical member 1,1,... face each other, and the second fitting recesses located on the horizontal member 2 face each other. Then, the second fitting recesses and second body 21 of the horizontal member 2 are inserted and fitted into the first fitting recesses of each vertical member 1,1,... and the first fitting recesses and first body 11 of each vertical member 1,1,... are inserted and fitted into the second fitting recesses, thereby fixing each vertical member 1,1,... and the horizontal member 2 to each other. The same operation is performed for the remaining horizontal members 2,2 to assemble each vertical member 1,1,... and each horizontal member 2,2,....

[0060] In such an assembled structure S, multiple vertical members 1,1,... each having a bow-shaped first body 11 are provided with multiple first fitting recesses, and multiple horizontal members 2,2,... each having a bow-shaped second body 21 are also provided with multiple second fitting recesses. By fitting the corresponding first fitting recesses and second fitting recesses together, each vertical member 1,1,... and each horizontal member 2,2,... can be assembled in a bowl-shaped lattice pattern easily, quickly, and with high precision. Therefore, even a bowl-shaped section can be assembled easily and quickly.

[0061] In this embodiment, the case in which second connecting portions 67, 67, 67 are provided protruding from the tips of the first arm portion 61 to the third arm portion 63 has been described. However, 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 along the longitudinal direction of the first arm portion 61 to the third arm portion 63.
