Description

Technical Field

[0005]

[0001] The present invention relates to a connecting member and an assembled frame.

Background Art

[0002] Conventionally, examples of assembled frames include goals for soccer, handball, hockey, etc., and targets for baseball and golf swing practice. In these, a plurality of pole members are connected by connecting members (corner members), and a net is stretched over the assembled frame. Some of these are used not only outdoors but also indoors for mini-soccer games, etc., and are used not only for competitions but also for games. For such goalposts or assembled frames for targets, for example, a modular sports net assembly as shown in Patent Document 1 has been proposed.

[0003] In Patent Document 1, there is disclosed a modular sports net assembly that can be easily assembled, arranged on a relatively flat ground, and disassembled for storage. It includes a tubular frame structure formed in the shape of a square prism, and a plurality of intermediate pole segments interconnect a plurality of corner units (connecting members). Each of the corner units has a protruding pole receiving portion extending along at least three independent axes, and each pole receiving portion receives the end of an intermediate pole segment.

[0004] On the other hand, another example of an assembled frame includes a decorative shelf or a mounting table on which a shelf board is laid across the assembled frame to place various articles, or a storage box that stores various articles with or without wall boards provided around the frame. For such assembled frames for mounting or storage, for example, an assembled frame of a distribution box as shown in Patent Document 2 has been disclosed.

[0005] Patent Document 2 discloses an assembly-type frame for a power distribution box that is particularly easy to assemble and can be disassembled, comprising an upper frame consisting of four horizontal posts and four corner members (connecting members) at the top, and a lower frame consisting of four horizontal posts and four corner members at the bottom, the upper frame and the lower frame being connected via four vertical posts, the corner members connecting two adjacent horizontal posts by screwing means, and heads being installed at both the upper and lower ends of each vertical post. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2002-253722 [Patent Document 2] Official Gazette No. 3179243 [Overview of the project] [Problems that the invention aims to solve]

[0007] However, the corner unit in Patent Document 1 includes protruding pole receiving portions extending along at least three independent axes (vertical and two horizontal directions), and is not a configuration that corresponds to connecting two pole members. Similarly, the corner member in Patent Document 2, although different in configuration from the corner unit in Patent Document 1, is similar in that it connects three pole members extending vertically and two horizontal directions. Therefore, in both Patent Document 1 and Patent Document 2, when only two pole members are connected, the portion provided for the third pole member is exposed and unused, which becomes an obstacle to use. Furthermore, in order to connect only two pole members without excess or deficiency, it becomes necessary to prepare a separate connecting member, which is another problem. The above problems apply to all connecting members used in the assembly of goal kits, shelves, chairs, tables, playground equipment (swings, jungle gyms, etc.), etc., when they are constructed using modular frames, in addition to the "net assembly" mentioned in Patent Document 1 and the "box" mentioned in Patent Document 2.

[0008] The present invention has been made in view of the above-mentioned problems, and aims to provide a connecting member that can easily and reliably connect pole members regardless of the number of members in one embodiment, and an assembly-type frame using the same. [Means for solving the problem]

[0009] To achieve the above objective, the present invention is understood by the following configuration. (1) A first aspect of the present invention is a connecting member for connecting a plurality of pole members, comprising: a first support portion that supports the longitudinal direction of a first pole member with its bottom surface; a second support portion connected so as to intersect with the first support portion and supporting the longitudinal direction of a second pole member with its bottom surface on the side of the superior angle when viewed from the bottom surface of the first support portion; a first contact portion disposed on one side of the first support portion along the longitudinal direction of the first pole member and abutting the first pole member on its side; and a second contact portion disposed on one or the other side of the second support portion along the longitudinal direction of the second pole member and abutting the second pole member on its side, wherein at least one of the first support portion and the first contact portion has a through portion on its respective bottom surface or side, and at least one of the second support portion and the second contact portion has a through portion on its respective bottom surface or side.

[0010] Here, the first support portion and the second support portion may each have at least one through portion and a protrusion on their respective bottom surfaces, and the first contact portion and the second contact portion may each have at least one through portion and a protrusion on their respective side surfaces.

[0011] Furthermore, the first support portion and the second support portion, as well as the first contact portion and the second contact portion, may be formed in a flat plate shape.

[0012] Furthermore, the first support portion and the second support portion, as well as the first contact portion and the second contact portion, may be formed in a curved plate shape.

[0013] Furthermore, the structure may also include reinforcing parts arranged to diagonally connect the inner surfaces of the inferior angle sides of the first support part and the second support part.

[0014] A second aspect of the present invention is an assembly frame comprising a plurality of pole members and a connecting member for connecting the plurality of pole members.

[0015] Here, the pole member has pole penetrations that intersect in cross-section with each pair of opposing wall surfaces, and when assembling the pole member and the connecting member, the pole penetrations of the pole member and the penetrations of the connecting member may be aligned. Furthermore, the pole member has multiple pole penetration points, An assembly-type frame formed in a rope tensioning shape by engaging multiple hook members with the pole penetration portion and engaging a rope between the multiple hook members, The hook member has an insertion portion that is detachably inserted into the pole penetration portion, It may also have a rope-locking portion extending from the insertion portion. Furthermore, the insertion portion may have a pivoting piece, and by elastically deforming the pivoting piece, the insertion portion may be configured to be locked to the pole penetration portion and to be released from that state. Furthermore, a length adjustment device may be provided for the rope stretched across the hook member. [Effects of the Invention]

[0016] According to the present invention, in one embodiment, a connecting member that can easily and reliably connect pole members regardless of their number, and an assembly-type frame using the same can be provided. [Brief explanation of the drawing]

[0018] Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as "embodiments") will be described in detail based on the attached drawings. In the embodiments and drawings, the front-front direction is described as the X direction, the left-right lateral direction as the Y direction, and the up-down vertical direction as the Z direction, but please note that these three directions are considered relative to each other.

[0019] (An example of a modular frame) First, with reference to Figures 1 to 7, an example of an assembled frame 1 using the connecting member 20 according to the first embodiment described later will be explained. As shown in Figures 1 to 7, the assembled frame 1 comprises a plurality of pole members 10 and a plurality of connecting members 20 that connect the plurality of pole members 10. The pole members 10 and the connecting members 20 are fastened together with bolts and nuts 30. The connecting member 20 used in the first embodiment will be described in detail in a later section.

[0020] Figure 1 shows a front perspective view of the assembly frame 1, Figure 2 a rear perspective view, Figure 3 a front view, Figure 4 a rear view, Figure 5 a top view, Figure 6 a bottom view, and Figure 7 a right side view. The left side view appears symmetrically to the right side view in Figure 7.

[0021] The modular frame 1 shown in Figures 1 to 7 is intended for use as a goal kit in a mini soccer game, but it is not limited to this. It can also be used as a goal for soccer, handball, hockey, etc., or as a target for baseball or golf practice. Furthermore, shelves can be placed across the assembled modular frame 1 to create a display shelf or stand for various items, or the frame can be made into a storage box for various items with or without wall panels. In addition, it can be applied to various modular frames such as chairs, tables, and playground equipment (swings, jungle gyms, etc.).

[0022] Referring to Figures 1 to 7, the pole members 10, in a front view (X direction), include a total of 11 pole members: upper left pole member 10a, upper rear pole member 10b, upper right pole member 10c, upper front pole member 10d, vertical left front pole member 10e, vertical left rear pole member 10f, vertical right rear pole member 10g, vertical right front pole member 10h, lower left pole member 10i, lower rear pole member 10j, and lower right pole member 10k. As this is intended for a goal in a mini soccer game, there is no pole member 10 at the lower front. When used as a goal, the assembled frame 1 is covered with netting on the top, left and right sides, and back, except for the front. In the following, when referring to the pole members 10 without specifying their positions, they will be referred to as pole member 10, and when referring to the pole members 10 with a specified position, they will be referred to as pole member 10a, etc.

[0023] Each pole member 10 is connected by a connecting member 20. Here, at the six corners connecting pole members 10a, 10d, and 10e; 10a, 10b, and 10f; 10b, 10c, and 10g; 10c, 10d, and 10h; 10i, 10j, and 10f; and 10j, 10k, and 10g, three pole members 10 are connected by two connecting members 20. On the other hand, at the two corners connecting pole members 10e and 10i, and 10h and 10k, two pole members 10 are connected by one connecting member 20.

[0024] One connecting member 20 (first connecting member) connects two pole members 10 (first pole member and second pole member), as will be described in more detail later. However, at the six corners where the three pole members 10 meet, another connecting member 20 (second connecting member) is used to connect one of the two pole members 10 (first pole member or second pole member) connected by the first connecting member to the third pole member 10 (third pole member).

[0025] Here, the pole member 10 has pole penetrations 11 that intersect in cross-sectional view, penetrating each of the opposing pairs of walls. In Figures 1 and 2, the one penetrating one pair of walls is referred to as pole penetration 11a, and the one penetrating the other pair of walls is referred to as pole penetration 11b. As will be described later, these pole penetrations 11 are used for fastening with bolts and nuts 30 in correspondence with the penetrations 21a and other parts provided on the connecting member 20, or for fitting with the protrusions 21b and other parts provided on the connecting member 20. In this specification, a "penetration provided in a pole member" is referred to as a "pole penetration." A "penetration provided in a connecting member" is simply referred to as a "penetration." If necessary, the names of the parts in which each "penetration" and "protrusion" is formed, as described in the [Explanation of Symbols] section below, may also be included, for example, penetration 21a (first contact penetration) and protrusion 21b (first contact protrusion). Furthermore, the pole penetration section 11 can also be used to attach a net by tying attachment strings when the assembled frame 1 is used as a goal or target, or to span shelves when used as a shelf or storage box. When the assembled frame 1 is used as a goal or target, strings or ropes of a suitable material for nets can be passed through the pole penetration section 11 of the vertical and horizontal pole members 10 to weave a net. Moreover, in the case of a chair, for example, the seat and backrest surfaces can be formed by passing strings or wide fabrics through the pole penetration section 11 of the vertical and horizontal pole members 10. In this way, the assembled frame 1 can be used for a variety of purposes by passing strings, ropes, wide fabrics, etc. through the pole penetration section 11 of the pole members 10.

[0026] The material of the pole member 10 is not particularly limited, and can be wood, metal, resin, etc. However, for use in games such as mini soccer games or indoors, wood is preferably used due to its appropriate weight, ease of manufacture, and ease of assembly. Of course, it can also be made of steel, PVC, etc. Regarding the shape of the pole member 10, Figures 1 to 27 show one with a square cross-section, but it is not limited to this. The cross-section may be a square with rounded or beveled corners, a hexagon, or a circle. When the cross-section of the pole member 10 is square, the two pole penetrations 11a and 11b will intersect in a cross shape in cross view. When the cross-section is hexagonal, if there are two penetrations like pole penetrations 11a and 11b, they may intersect in an X shape, and if there is one more penetration, making a total of three, they may intersect in an asterisk shape. When the cross-section of the pole member 10 is circular, it may be cross-shaped, X-shaped, asterisk-shaped, etc., depending on the desired number of penetrations.

[0027] Here, we will explain an example where the pole member 10 is made of wood. For example, in the case of wood, in addition to 2x2 lumber (38mm x 38mm) with a square cross-section, 2x4 lumber (38mm x 89mm) with a rectangular cross-section may be used, but a square cross-section is preferable because its orientation does not matter, thus improving the workability of assembly. In this specification, except for Figures 28 to 31, an example using 2x2 lumber is shown, where the first pole penetrations 11a and 11b from the end of the pole member 10 are located at a position of 19mm, which is half of 38mm, and the pitch between the pole penetrations 11a and 11b is 38mm. By setting the position of the first pole penetrations 11a and 11b at 19mm from the end, the pole members 10 can be connected neatly without gaps when connected in a T-shape. However, the dimensions are not limited to these sizes. If the timber is a square timber with a square cross-section, the position of the first pole penetrations 11a and 11b from the end is set to half the side length, and the pitch between the pole penetrations 11a and 11b is set to the side length, allowing connection to be made in a position close to any desired location. Note that the spacing between the penetrations 21a etc. and the protrusions 21b in the connecting members 20, 40, 50, and 60 described below is set to 38 mm, matching the pitch between the pole penetrations 11a and 11b, assuming that 2x2 timber is used as the pole member 10.

[0028] (Connecting member according to the first embodiment) Next, with reference to Figures 8 to 15, the connecting member 20 according to the first embodiment will be described. As shown in Figures 8 to 15, the connecting member 20 includes a first contact portion 21, a second contact portion 22, a first support portion 23, a second support portion 24, and a reinforcing portion 25. The connecting member 20 is assumed to be a pole member 10 with a square cross-section, and the first support portion 23 and the second support portion 24, as well as the first contact portion 21 and the second contact portion 22, are formed in a flat plate shape. Here, an embodiment with a reinforcing portion 25 is shown, but the reinforcing portion 25 may be provided as needed, taking into consideration the application of the assembled frame 1 and the material and strength of the connecting member 20. The same applies to the connecting member 40 according to the second embodiment, the connecting member 50 according to the third embodiment, and the connecting member 60 according to the fourth embodiment, which will be described later.

[0029] Figure 8 shows a front perspective view of the connecting member 20, Figure 9 shows a rear perspective view, Figure 10 shows a front view, Figure 11 shows a rear view, Figure 12 shows a top view, Figure 13 shows a bottom view, Figure 14 shows a left side view, and Figure 15 shows a right side view.

[0030] As described above, one connecting member 20 connects two pole members 10, with the first support portion 23 supporting the longitudinal direction of the first pole member 10 at its bottom surface, and the second support portion 24, which is connected so as to intersect with the first support portion 23, supporting the longitudinal direction of the second pole member 10 at its bottom surface. Here, the bottom surface of the second support portion 24 refers to the bottom surface on the superior angle side when viewed from the bottom surface of the first support portion 23. Furthermore, the bottom surface is the surface on which the side of the pole member comes into contact with the first support portion 23 and the second support portion 24 when the side of the pole member is supported by the first support portion 23 and the second support portion 24. Figures 8 to 15 illustrate a configuration in which the first support portion 23 and the second support portion 24 intersect at a right angle R. However, in order to achieve the desired shape of the assembled frame 1, the lower angle side of the first support portion 23 and the second support portion 24 may be made acute or obtuse.

[0031] The first contact portion 21 is located on one side of the first support portion 23 along the longitudinal direction of the first pole member 10, and when viewed from the front (X direction), it abuts the wall surface of the first pole member 10 on its side. The second contact portion 22 is located on one side of the second support portion 24 along the longitudinal direction of the first pole member 10, and abuts the wall surface of the second pole member 10 on its side. Here, the side of the first support portion 23 on which the first contact portion 21 is located and the side of the second support portion 24 on which the second contact portion 22 is located refer to the same side (the front side in both Figures 8 and 10).

[0032] The reinforcing portion 25 is arranged to diagonally connect the inner surfaces of the inferior angle sides of the first support portion 23 and the second support portion 24. In each figure, the reinforcing portion is shown to be formed in such a way that it covers the connection portion of the first support portion 23 and the second support portion 24 in a triangular pyramidal shape, but other configurations are also possible. For example, a plate-like or rod-like structure may be placed across the connection portion of the first support portion 23 and the second support portion 24.

[0033] The first support portion 23 has a through portion 23a on its bottom surface, on the end furthest from the second support portion 24, and similarly, the second support portion 24 has a through portion 24a on its bottom surface, on the end furthest from the first support portion 23. These through portions 23a and 24a correspond to the pole through portions 11a and 11b provided on the pole member 10 and are used for fastening with bolts and nuts 30.

[0034] The first contact portion 21 has a through portion 21a on its side surface, on the end furthest from the second contact portion 22, and similarly, the second contact portion 22 has a through portion 22a on its side surface, on the end furthest from the first contact portion 21. These through portions 21a and 22a are also used for fastening with bolts and nuts 30, corresponding to the pole through portions 11a and 11b provided on the pole member 10.

[0035] In addition, the above describes an embodiment in which through-holes 23a, 21a, 24a, and 22a are provided on the bottom surface of the first support portion 23, the side surface of the first contact portion 21, the bottom surface of the second support portion 24, and the side surface of the second contact portion 22. However, taking into account the intended use of the assembled frame 1 and the material and strength of the connecting member 20, it is also possible to have at least one of the first support portion 23 and the first contact portion 21 have through-holes 23a and 21a on their respective bottom or side surfaces, and at least one of the second support portion 24 and the second contact portion 22 have through-holes 24a and 22a on their respective bottom or side surfaces. In other words, the through-hole 23a on the bottom surface of the first support portion 23 and the through-hole 24a on the bottom surface of the second support portion 24 may be combined as follows: the through-hole 23a on the bottom surface of the first support portion 23 and the through-hole 22a on the side surface of the second contact portion 22; the through-hole 21a on the side surface of the first contact portion 21 and the through-hole 24a on the bottom surface of the second support portion 24; and the through-hole 21a on the side surface of the first contact portion 21 and the through-hole 22a on the side surface of the second contact portion 22. The same applies to the connecting member 40 according to the second embodiment, the connecting member 50 according to the third embodiment, and the connecting member 60 according to the fourth embodiment, which will be described later.

[0036] In Figure 8 and other figures, the through-holes 23a, 21a, 24a, and 22a are shown as circular holes with closed edges penetrating the bottom surface of the first support portion 23, the side surface of the first contact portion 21, the bottom surface of the second support portion 24, and the side surface of the second contact portion 22, respectively, where they are provided. However, the shape is not limited to this. For example, the through-holes 23a, 21a, 24a, and 22a may also be slits penetrating the respective surfaces on which they are provided. The through-holes 23a, 21a, 24a, and 22a are used for fastening with bolts and nuts 30 in correspondence with the pole through-holes 11a and 11b provided on the pole member 10. However, even with slits, the same effect as with circular holes can be obtained by fastening with bolts and nuts 30, and it is also possible to flexibly adjust the position with respect to the pole member 10. The shape of the slit is not particularly limited; for example, it may be U-shaped with the ends furthest from the center open, or oval-shaped with the periphery closed.

[0037] In addition to the above, the first support portion 23 has a protrusion 23b on its bottom surface that projects inward from the connecting member 20 (towards the pole member 10) and is closer to the second support portion 24. Similarly, the second support portion 24 has a protrusion 24b on its bottom surface that projects toward the pole member 10 and is closer to the first support portion 23. These protrusions 23b and 24b fit into pole penetration portions 11a and 11b provided in the pole member 10. As a result, the first support portion 23 and the second support portion 24 are fastened to the pole member 10 by the penetration portions 23a and 24a, and together they provide the same effect as two-point fastening in the connection between the pole member 10 and the connecting member 20, preventing rattling.

[0038] Furthermore, the first contact portion 21 has a protrusion 21b on its side that projects toward the pole member 10, on the side closer to the second contact portion 22, and similarly, the second contact portion 22 has a protrusion 22b on its side that projects toward the pole member 10, on the side closer to the first contact portion 21. As a result, the first contact portion 21 and the second contact portion 22 are fastened to the pole member 10 by the through portions 21a and 22a, and together they provide the same effect as two-point fastening in the connection between the pole member 10 and the connecting member 20, preventing rattling. Consequently, the connection between the pole member 10 and the connecting member 20 is in the form of four-point fastening by two-point fastening at the first support portion 23 and two-point fastening at the first contact portion 21 (or two-point fastening at the second support portion 24 and two-point fastening at the second contact portion 22).

[0039] Hereinafter, we have described an example in which the through-parts 21a, 22a, 23a, and 24a are located on the far end side when viewed from the intersection of the first support part 23 and the second support part 24, and the protrusions 21b, 22b, 23b, and 24b are located on the near end when viewed from the intersection of the first support part 23 and the second support part 24 (see Figure 11 in particular). However, the positions of the through-parts 21a, 22a, 23a, and 24a and the protrusions 21b, 22b, 23b, and 24b are not limited to this. For example, if the connecting member 20 is relatively large in size relative to the pole member 10, the through-parts 21a, 22a, 23a, and 24a and the protrusions 21b, 22b, 23b, and 24b may be located in opposite positions.

[0040] Furthermore, while the above describes an example in which one through portion 21a, 22a, 23a, 24a and one protrusion 21b, 22b, 23b, 24b are provided on the first contact portion 21, the second contact portion 22, the first support portion 23, and the second support portion 24, the number of these is not limited to this. For example, if the connecting member 20 is relatively large in size relative to the pole member 10, at least one of the first contact portion 21, the second contact portion 22, the first support portion 23, and the second support portion 24 may be extended to provide multiple through portions (for example, multiple through portions 21a, 21a on the first contact portion 21) and multiple protrusions (for example, multiple protrusions 21b, 21b on the first contact portion 21).

[0041] Thus, depending on its size and the strength required for the assembled frame 1, the connecting member 20 can be formed such that the first support portion 23 and the second support portion 24 each have at least one through portion 23a, 24a and a protrusion 23b, 24b on their respective bottom surfaces, and the first contact portion 21 and the second contact portion 22 each have at least one through portion 21a, 22a and a protrusion 21b, 22b on their respective sides. The same applies to the connecting member 40 according to the second embodiment, the connecting member 50 according to the third embodiment, and the connecting member 60 according to the fourth embodiment, which will be described later.

[0042] As shown in Figures 10, 13, and 14, the connecting member 20 has the following tapered edges formed on the inferior angle side connecting the first support portion 23 and the second support portion 24: an edge T1 tapered toward the tip at a position corresponding to the first contact portion 21, an edge T3 tapered toward the tip at a position corresponding to the second contact portion 22, and an edge T2 tapered toward the tip at a position corresponding to the continuous portion of the first contact portion 21 and the second contact portion 22.

[0043] The material of the connecting member 20 is not particularly limited, and can be made of wood, metal, or resin. However, under conditions of use for play or indoors, such as in goal kits for mini soccer games, resin can be suitably used due to its light weight, ease of manufacture, and ease of assembly. When the connecting member 20 is made of resin, the reinforcing part 25 may be made of metal depending on its shape (for example, rod-shaped). Furthermore, although the figures show the connecting member 20 corresponding to a pole member 10 with a square cross-section, it is not limited to this. The cross-sections of the first contact part 21 and the first support part 23, the second contact part 22 and the second support part 24 may be, for example, a square with rounded or beveled corners, or a circle (including an arc-shaped curve), depending on the cross-section of the pole member 10.

[0044] (Connecting member according to the second embodiment) The connecting member 40 according to the second embodiment will be described with reference to Figures 16 and 17. As shown in Figures 16 and 17, the connecting member 40 includes a first contact portion 41, a second contact portion 42, a first support portion 43, a second support portion 44, and a reinforcing portion 45.

[0045] Figure 16 shows a front perspective view of the connecting member 40, and Figure 17 shows a rear perspective view.

[0046] The connecting member 40 is basically the same as the connecting member 20, but as shown in Figures 16 to 17, on the inferior angle side connecting the first support portion 43 and the second support portion 44, unlike the connecting member 20, a plate-like portion T4 is provided from the first contact portion 41 to the second contact portion 42, instead of edges T1, T3, and T2, on the inferior angle side connecting the first support portion 43 and the second support portion 44, which is formed in a material-removing manner. The other elements are the same as the connecting member 20 according to the first embodiment, so the explanation will be omitted by simply changing the reference numerals of the corresponding elements (for example, the through portion 21a and protrusion 21b provided on the first contact portion 21 according to the first embodiment will be read as the through portion 41a and protrusion 41b provided on the first contact portion 41 according to the second embodiment).

[0047] (Assembly Instructions) The following describes the procedure for assembling the modular frame 1, using the connecting member 20 of the first embodiment with reference to Figures 18 to 23. The same applies when using the connecting member 40 according to the second embodiment, or the connecting member 50 according to the third embodiment and the connecting member 60 according to the fourth embodiment, which will be described later. Although Figures 18 to 23 illustrate a connection method different from the connection method of the connecting member 20 shown in Figures 1 to 7 (the position where it is attached to the pole member 10; the same applies hereinafter), any connection method is acceptable. There is no difference in the function and effect of the connecting members 20, 40, 50, and 60. In this respect, the ability to select the connection method in this way demonstrates the flexibility to flexibly adapt the connection method using the connecting members 20, 40, 50, and 60 according to the usage conditions of the modular frame 1.

[0048] First, as shown in Figure 18, three pole members 10 (here, pole members 10 cut to a shorter length for illustrative purposes are shown), two connecting members 20, and three bolts and nuts 30 are prepared as components for the assembled frame 1.

[0049] Next, as shown in Figure 19, two pole members 10, a first pole member 10i and a second pole member 10j, are arranged horizontally in an L-shape, and the first connecting member 20 is positioned at their ends. At this time, the first connecting member 20 is positioned to support the first pole member 10i on the first support portion 23, so that its end does not exceed the connection portion between the first support portion 23 and the second support portion 24, and to support the second pole member 10j on the second support portion 24, so that its end does not exceed the connection portion between the second support portion 24 and the first support portion 23. At this time, the through portion 23a of the first support portion 23 and the through portion 24a of the second support portion 24 on the first connecting member 20 are located in positions corresponding to the pole through portion 11b of the first pole member 10i and the pole through portion 11b of the second pole member 10j, respectively.

[0050] Next, as shown in Figure 20, the third pole member 10f is positioned vertically in the space between the ends of the first pole member 10i and the second pole member 10j. At this time, the second connecting member 20 supports the second pole member 10j on the first support portion 23 so that its end does not exceed the connection portion between the first support portion 23 and the second support portion 24, and supports the third pole member 10f on the second support portion 24 so that its end exceeds the connection portion between the second support portion 24 and the first support portion 23. At this time, the through portion 23a of the first support portion 23 and the through portion 24a of the second support portion 24 on the second connecting member 20 are located in positions corresponding to the pole through portion 11a of the second pole member 10j and the pole through portion 11b of the third pole member 10f, respectively. Although it is a blind spot in Figure 20, at this time, the through-hole 22a of the second contact portion 22 of the second connecting member 20 is in a position corresponding to the pole through-hole 11a of the third pole member 10f (see Figures 21 and 22 below).

[0051] Next, as shown in Figure 21, the first connecting member 20 is fastened to the first pole member 10i and the second pole member 10j via the through-holes 23a and 24a of the first connecting member 20 using bolts and nuts 30. Then, the second connecting member 20 is fastened to the third pole member 10f via the through-hole 22a of the second connecting member 20 using bolts and nuts 30.

[0052] Here, Figure 22 shows the state immediately before assembling the third pole member 10f. Figure 23 shows a magnified view of the second connecting member 20 in Figure 22. As shown in both figures, the second contact portion 22 of the connecting member 20 is provided with a through portion 22a and a protrusion 22b, as described above. As shown in Figure 20, the through portion 22a and the pole through portion 11a of the third pole member 10f are fastened together with a bolt and nut 30, but at that time, the protrusion 22b fits into a pole through portion 11a that is separate from the pole through portion 11a fastened with the bolt and nut 30 and is located below it. This provides the same effect as two-point fastening in the connection between the pole member 10 and the connecting member 20, and prevents rattling.

[0053] (Connecting member according to the third embodiment) Referring to Figures 24 to 27, the connecting member 50 according to the third embodiment will be described. As shown in Figures 24 and 25, the connecting member 50 includes a first contact portion 51, a second contact portion 52, a first support portion 53, a second support portion 54, and a reinforcing portion 55.

[0054] Figure 24 is a front perspective view of the connecting member 50, Figure 25 is a rear perspective view, Figure 26 is a front perspective view illustrating the assembly of the connecting member 50 and the pole member 10, and Figure 27 is a rear perspective view.

[0055] As shown in Figures 24 and 25, the connecting member 50 differs from the connecting member 20 according to the first embodiment and the connecting member 40 according to the second embodiment in that the first contact portion 51 of the first support portion 53 is located on one side along the longitudinal direction of the first pole member 10, and when viewed from the front (X direction), it contacts the wall surface of the first pole member 10 on its side. The second contact portion 52 is located on the other side along the longitudinal direction of the first pole member 10 of the second support portion 54, and contacts the wall surface of the second pole member 10 on its side. Here, one side of the first support portion 53 on which the first contact portion 51 is provided and the other side of the second support portion 54 on which the second contact portion 52 is provided refer to the sides on opposite sides of the first support portion 53 and the second support portion 54 (in Figures 24 and 25, the first contact portion 51 is on the front side and the second contact portion 52 is on the back side).

[0056] Other aspects are the same as those of the connecting member 20 according to the first embodiment, so the explanation will be omitted by simply changing the reference numerals of the corresponding elements (for example, changing the through portion 21a and protrusion 21b provided on the first contact portion 21 according to the first embodiment to the through portion 51a and protrusion 51b provided on the first contact portion 51 according to the third embodiment).

[0057] The procedure for assembling the connecting member 50 and the pole member 10 is the same as for the connecting member 20 according to the first embodiment and the connecting member 40 according to the second embodiment, but an example of assembling two pole members 10i and 10j is shown in Figures 26 and 27.

[0058] (Connecting member according to the fourth embodiment) Referring to Figures 28 to 31, the connecting member 60 according to the fourth embodiment will be described. As shown in Figures 28 and 29, the connecting member 60 includes a first contact portion 61, a second contact portion 62, a first support portion 63, a second support portion 64, and a reinforcing portion 65.

[0059] Figure 28 is a front perspective view of the connecting member 60, Figure 29 is a rear perspective view, Figure 30 is a front perspective view illustrating the assembly of the connecting member 60 and the pole member 12, and Figure 31 is a rear perspective view.

[0060] As shown in Figures 24 and 25, the connecting member 60 differs from the connecting member 20 according to the first embodiment, the connecting member 40 according to the second embodiment, and the connecting member 50 according to the third embodiment. It is assumed to be a pole member 12i, 12j (see Figures 30 and 31) with a circular cross-section, and the first support portion 63 and the second support portion 64, as well as the first contact portion 61 and the second contact portion 62, are formed in a curved plate shape. Here, in Figures 28 and 29, similar to the connecting member 20 according to the first embodiment and the connecting member 40 according to the second embodiment, one side of the first support portion 63 on which the first contact portion 61 is disposed and one side of the second support portion 64 on which the second contact portion 62 is disposed are on the same side (in Figures 28 and 29, both are the back side). However, similar to the connecting member 50 according to the third embodiment, the first contact portion 61 may be disposed on one side of the first support portion 63, while the second contact portion 62 may be disposed on the other side of the second support portion 64.

[0061] Other aspects are the same as those of the connecting member 20 according to the first embodiment, so the explanation will be omitted by simply changing the reference numerals of the corresponding elements (for example, changing the through portion 21a and protrusion 21b provided on the first contact portion 21 according to the first embodiment to the through portion 61a and protrusion 61b provided on the first contact portion 61 according to the third embodiment). However, in the connecting member 60, since the first support portion 63, the second support portion 64, the first contact portion 61, and the second contact portion 62 are formed in a curved plate shape, the through portions 63a, 64a, 61a, and 62a provided on each of them are provided with flat heads on the outside of the connecting member 60 (opposite side from the pole member 12) for convenience in fastening the bolts and nuts 30. Furthermore, the pole members 12i and 12j have pole penetration portions 13, 13a, and 13b, similar to the embodiment described above.

[0062] The procedure for assembling the connecting member 60 and the pole member 12 is the same as for the connecting member 20 according to the first embodiment and the connecting member 40 according to the second embodiment, but an example of assembling two pole members 12i and 12j is shown in Figures 30 and 31. Note that the bolts and nuts 30 are not shown in Figures 30 and 31.

[0063] (Assembly frame according to the fifth embodiment) The assembly frame according to the fifth embodiment will be described with reference to Figures 32 to 36. The assembled frame 1 according to this embodiment relates to an assembled frame 1 in which a rope 76 is stretched between a plurality of pole members 10 when the assembled frame 1 is constructed using the connecting members according to each of the above embodiments. First, each pole member 10 is configured to have multiple pole penetrations 11 in the direction in which the pole member 10 extends (longitudinal direction). It is preferable to set the pitch of the pole penetration portion 11 to be the same as the width of the pole member 10. Furthermore, it is preferable that the pole penetration portions 11 are provided at regular intervals in the longitudinal direction of the pole member 10, and more preferably that they are provided over the entire longitudinal area of ​​the pole member 10. Then, multiple pole members 10, each having multiple pole penetration sections 11, are combined using connecting members to form an assembly-type frame 1, which is a structure on which a rope 76 can be stretched.

[0064] The shape and structure of the prefabricated frame 1 are not particularly limited, but it is often composed of a frame body enclosed by pole members 10 on its outer edge. A rectangular shape is frequently used for such a frame body. Figure 32 is a front view showing an example of a modular frame. This prefabricated frame 1 has a base frame 71, and a pair of pole members 10 are erected as a column frame 72 at the center in the front-to-back direction of the base frame 71. An upper frame 73, an intermediate frame 74, and a lower frame 75 are then fixed to the column frame 72 with the aforementioned connecting members. This prefabricated frame 1 forms a structure similar to a screen. In the prefabricated frame 1 shown in Figure 32, a small rectangular first frame 77 is formed on the upper side, and a larger rectangular second frame 78 is formed on the lower side. The prefabricated frame 1 is constructed by using hook members 80, ropes 76, and length adjusters 81 to stretch the ropes 76 between the two frame bodies 77 and 78.

[0065] Note that this prefabricated frame 1 is a structure shown for illustrative purposes, and the overall shape will differ depending on the intended use of the prefabricated frame 1 to which each rope 76 is stretched. For example, the structure of the prefabricated frame 1 will change depending on the intended use of the items to which the rope 76 is stretched, such as goal kits as shown in Figure 1 of the first embodiment, locking plates (not shown) for suspending various items from the rope 76, furniture such as chairs, storage boxes, and tables (not shown), or play equipment (not shown).

[0066] Figure 33 is a perspective view showing one example of the hook member configuration attached to a pole penetration, Figure 34 is a perspective view of the hook member, and Figure 35 is a side view of the hook member. The hook member 80 has at least an insertion portion 83 that is detachably inserted into and locked in the pole penetration portion 11, and a rope locking portion 84 that extends from the insertion portion 83. The hook member 80 also has a main body portion 92 that connects the insertion portion 83 to the rope locking portion 84. In the configurations shown in Figures 33 to 35, the insertion portion 83 is an insert having a length of more than half, preferably approximately the same length as, the length of the pole penetration portion 11, and the vertical cross-sectional shape of the insertion portion 83 is formed to be circular, just like the shape of the pole penetration portion 11.

[0067] As shown in Figures 33 and 35, the hook member 80 is described with reference to the front-to-back direction X, the side-to-side direction Y (left-to-right direction), and the up-to-down direction Z. The main body 92 has a base portion 85 extending downward from the base side of the insertion portion 83, a support portion 87 extending rearward from the base portion 85 parallel to the insertion portion 83, and a hanging portion 88 extending downward from the end of the support portion 87. A rope locking portion 84 is connected to the hanging portion 88. In addition, there is a detachment prevention portion 89 projecting upward from the front side of the rope locking portion 84. The shape of the component extending from the insertion portion 83 to the base portion 85, support portion 87, and hanging portion 88, and connected to the rope locking portion 84, is roughly S-shaped or roughly figure-five. In the configuration shown in Figures 33 to 35, the base portion 85 is provided with a tongue portion 90 extending downward, and this tongue portion 90 has a surface facing the tip of the rope locking portion 84. The presence of the tongue portion 90 on the base portion 85 makes it easier to grasp the hook member 80, and thus easier to insert the insertion portion 83 into the pole penetration portion 11.

[0068] Furthermore, a gap 91 is formed between the tip of the rope locking portion 84 and the tongue portion 90 through which the rope 76 passes. The rope 76, which is held in place by the rope locking portion 84, is less likely to fall out due to the anti-slip portion 89 and the tongue portion 90. Furthermore, a pivoting piece 93 is formed on the insertion portion 83, extending from the tip end towards the base end, and swings vertically with the tip end as the base. By elastically deforming this pivoting piece 93, the insertion portion 83 can be positioned in a state where it is locked to the pole penetration portion 11 and in a released state. This configuration allows the insertion portion 83 to be stably maintained in the pole penetration portion 11 while also being detachable. The rope locking portion 84 is preferably provided on the inner surface side of the frame formed by the pole member 10, and more preferably on the side facing the inner surface of the frame. The presence of the rope locking portion 84 on the inner surface side of the frame allows the rope 76 to be stretched inside the frame without protruding from the outer surface of the pole member 10. The hook member 80 has at least one insertion portion 83. While the hook member 80 often has one or two insertion portions 83, a configuration with three or more can be adopted when a large force is applied to the rope. Furthermore, a configuration can be adopted in which two insertion parts 83 are provided facing each other so that the insertion part 83 can be inserted into two opposing pole penetration parts 11 as needed.

[0069] Figure 36 is a perspective view showing an example of a length adjustment device. As shown in Figure 32, the length adjuster 81 is a component that allows for easy adjustment of the length of the rope stretched between the starting hook member 80a and the ending hook member 80b. As shown in Figure 36, the length adjustment device 81 is constructed by providing two rope insertion holes 95 in a roughly oval plate 94, and bending one end of the roughly oval plate 94 at a predetermined angle. Furthermore, length adjusters 81 are provided at both ends of a single rope 76, and the rope is doubled at the length adjuster 81 to form a loop-shaped section 96. By securing these two ring-shaped portions 96 to the starting point hook member 80a and the ending point hook member 80b of the frame, a rope tensioning shape is formed that allows for length adjustment of the rope 76. Furthermore, the length adjustment device 81 does not have to be configured as shown in Figure 36; any length adjustment device that allows the length of the rope 76 to be adjusted appropriately with simple operation can be used.

[0070] This section explains the assembly process and advantages of the modular frame 1. (1) The pole members 10, each having a pole penetration portion 11, are assembled with connecting members to form a pre-fabricated frame 1 of a predetermined shape. (2) In order to achieve a rope tension shape that matches the intended use, multiple hook members 80 are attached to predetermined positions in the pole penetration portion 11. (3) One loop portion 96 made by the length adjustment device 81 is attached to the rope locking portion 84 of the starting hook member 80a, and the other loop portion 96 is attached to the ending hook member 80b to create a rope tension shape. If at least one intermediate hook member 80c is provided between the starting hook member 80a and the ending hook member 80b, the rope 76 is attached to the rope locking portion 84 of the intermediate hook member 80c in a continuous, straight line manner to create the desired rope tension shape.

[0071] Furthermore, the construction of a rope-tensioned structure will be explained using the modular frame shown in Figure 32 as an example. In Figure 32, one hook member 80 is attached to each of the areas of the pair of column frames 72 corresponding to the first frame 77, and six hook members 80 are attached laterally to the upper frame 73 and intermediate frame 74 corresponding to the first frame 77. In the first frame 77, the rope locking portions 84 of the total of 14 hook members 80 are all attached to the inner surface of the first frame 77. In this configuration, a rope 76 is stretched horizontally across a pair of hook members 80 provided on the column frame 72. For the 12 hook members 80 on the upper frame 73 and intermediate frame 74 corresponding to the first frame 77, two adjacent hook members 80 on the upper frame 73 are designated as the starting hook member 80a and the ending hook member 80b, respectively, and two hook members 80 attached to the intermediate frame 74 at opposing positions are designated as intermediate hook members 80c, and the rope 76 is attached in sequence along a path resembling a single continuous line. As a result, a rope-tensioned shape can be formed within the first frame 77, with one horizontal rope and six vertical ropes stretched across it. For the second frame 78, one hook member 80 is attached to each of the areas of the pair of column frames 72 and intermediate frame 74 corresponding to the second frame 78, and two hook members 80 are attached to the lower frame 75. Then, a rope 76 is stretched diagonally between the hook members 80, and multiple ring-shaped parts 96 are attached to the rope-locking parts 84 of the hook members 80, thereby forming a rope tensioning shape resembling a star polygon.

[0072] (4) When creating a rope tensioned shape, if there is excess length of rope 76, or if slack in rope 76 or the tension of rope 76 needs to be adjusted, this can be easily done by adjusting the length of the double rope using the length adjustment tool 81. Furthermore, if you wish to modify the rope tensioning shape after assembling the modular frame 1, you can do so by adding or removing hook members 80, or by changing the tensioning method. (5) Furthermore, the assembly frame 1 can be disassembled into individual pole members 10 and connecting members, so a new assembly frame 1 of a different shape can be constructed using the disassembled members. Also, since the hook member 80 can be detachably attached to the pole penetration portion 11 of the pole member 10, the hook member 80 can also be used in the new assembly frame 1.

[0073] Furthermore, the assembly frame according to the fifth embodiment can also be constructed using or without the connecting members 20, 40, 50, and 60 described in the first to fourth embodiments. In those cases as well, the assembly frame will be constructed by combining multiple pole members, each having multiple pole penetrations. Examples of such modular frames include: A pole member having multiple pole penetration points, It comprises multiple hook members, a rope, and a length adjuster for the rope, A prefabricated frame formed into a rope tensioning shape by the aforementioned hook member, The pole penetration portions are provided at regular intervals in the longitudinal direction of the pole member. The hook member has an insertion portion that is detachably inserted into the pole penetration portion, Having a rope locking portion extending from the insertion portion, A modular frame characterized by the following: There is. Furthermore, as a method for manufacturing prefabricated frames, for example, A pole member having multiple pole penetration points, It has multiple hook members and a rope, A method for manufacturing an assembled frame formed into a rope tensioning shape by the aforementioned hook member, The pole penetration portions are provided at regular intervals in the longitudinal direction of the pole member. The hook member has an insertion portion that is detachably inserted into the pole penetration portion, It has a rope locking portion extending from the insertion portion, The hook member has a starting point hook member, an ending point hook member, and at least one intermediate hook member. A method for manufacturing an assembly frame, characterized in that the rope is secured to the rope-locking portion of the intermediate hook member in a single continuous line to form the rope-tensioned shape, There is.

[0074] Although the present invention has been described above using the first to fifth embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the first to fifth embodiments. It will be obvious to those skilled in the art that various modifications or improvements can be made to the first to fifth embodiments. Furthermore, it is clear from the claims that such modified or improved forms may also be included in the technical scope of the present invention. [Industrial applicability]

[0075] The connecting member and the assembled frame using the same according to the present invention allow pole members to be easily and reliably connected regardless of the number of pole members using a single type of connecting member. This makes it possible to provide various structures with an assembled frame structure, such as goal kits for soccer, targets for baseball and golf practice ranges, display shelves, stands, storage boxes, chairs, tables, and playground equipment (swings, jungle gyms, etc.), which is extremely useful in industry.
