Connecting member

Abstract

To provide a connecting member that can significantly improve workability. [Solution] The connecting member (1) comprises a base portion (2), a support portion (3) rotatably mounted on one side of the base portion (2), and a cover portion (4) rotatably mounted on one side of the support portion (3). When fixing the first support pillar, the support portion (3) is rotated to sandwich the first support pillar between the support portion (3) and the base portion (2), thereby fixing it. When fixing the second support pillar, the cover portion (4) is rotated to sandwich the second support pillar between the cover portion (4) and the support portion (3), thereby fixing it. This allows the first support pillar and the second support pillar to be fixed in an orthogonal state. Furthermore, assembly can be performed from one direction, and because the parts are connected, there is no need to consider the assembly procedure.

Description

[Technical Field]

[0001] The present invention relates to a connecting member. [Background technology]

[0002] BACKGROUND ART A connecting member called a cross muff (see, for example, Patent Document 1) is known as a member for fixing supports such as shafts and pipes in an orthogonal state.

[0003] However, the above-described connecting member has the following problems, which will be explained in detail with reference to Figs. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 3-257256 Summary of the Invention [Problem to be solved by the invention]

[0005] When attempting to connect a rod-shaped first shaft S1 extending in the left-right direction shown in Figure 7(a) and a rod-shaped second shaft S2 extending in the up-down direction shown in Figure 7(a) in a lattice pattern as shown in Figure 7(a), a connecting member 100 as shown in Figure 7(b) is used.

[0006] As shown in FIG. 8, the connecting member 100 is mainly composed of a main body 101, a first cover portion 102, and a second cover portion 103. As shown in FIG. 8, the main body 101 is formed in a thick, approximately circular shape, and a main body vertical groove 101b having a concave shape extending in the vertical direction is provided at the center of the right side surface 101a. Furthermore, as shown in FIG. 8, a pair of threaded bolt holes 101a1 are provided in the right side surface 101a at a distance from each other and extend through the main body vertical groove 101b in the left-right direction (from the right side surface 101a to the left side surface 101c of the main body 101). Furthermore, as shown in FIG. 8, a pair of threaded bolt holes 101b1 are provided in the main body vertical groove 101b at a distance from each other and extend through the main body vertical groove 101b in the left-right direction (from the right side surface 101a to the left side surface 101c of the main body 101). As shown in FIG. 8, a main body lateral groove 101d having a concave shape is provided in the center of the left side surface 101c of the main body 101, extending in the front-rear direction.

[0007] On the other hand, as shown in Fig. 8, the first cover part 102 is formed in a substantially semispherical shape, and a first cover lateral groove 102b having a concave shape is provided in the front-to-rear direction at the center of the right side surface 102a. Furthermore, as shown in Fig. 8, a pair of bolt insertion holes 102a1 are provided spaced apart in the right side surface 102a and penetrate in the left-right direction in the figure (from the right side surface 102a to the left side surface 102c of the first cover part 102).

[0008] On the other hand, as shown in Fig. 8, the second cover part 103 is formed in a substantially semispherical shape, and a second cover vertical groove 103b having a concave shape is provided in the center of the left side surface 103a in the up-down direction. Furthermore, as shown in Fig. 8, a pair of bolt insertion holes 103c1 are provided spaced apart in the right side surface 103c and penetrate in the left-right direction in the figure (from the right side surface 103c to the left side surface 103a of the second cover part 103).

[0009] The connecting member 100 configured as described above is assembled as follows: That is, as shown in Fig. 8, the right side surface 102a of the first cover part 102 is placed on the left side surface 101c of the main body 101, and the pair of bolts B1 are inserted into the pair of bolt insertion holes 102a1 and the pair of bolt holes 101b1, and then screwed together. In this way, the first cover part 102 is attached and fixed to the main body 101.

[0010] 8, the left side surface 103a of the second cover part 103 is placed on the right side surface 101a of the main body 101, and the pair of bolts B2 are inserted into the pair of bolt insertion holes 103c1 and the pair of bolt holes 101a1 and screwed in place. This means that the second cover part 103 is attached and fixed to the main body 101.

[0011] Thus, the connecting member 100 is assembled in the above manner, whereby the first shaft S1 and the second shaft S2 can be fixed in a perpendicular state as shown in Fig. 7(b). This point will be explained in more detail.

[0012] To fix the first shaft S1 and the second shaft S2 in a perpendicular state, first, as shown in Fig. 9(a), the first shaft S1 is fitted into the main body lateral groove 101d of the main body 101. Next, as shown in Fig. 9(b), the first shaft S1 is also fitted into the first cover lateral groove 102b. Then, as shown in Fig. 8, the right side surface 102a of the first cover part 102 is overlapped with the left side surface 101c of the main body 101, and a pair of bolts B1 are inserted into the pair of bolt insertion holes 102a1 and the pair of bolt holes 101b1 and screwed together. As a result, as shown in Fig. 9(b), the first cover part 102 and the main body 101 are attached and fixed with the first shaft S1 sandwiched therebetween, and the position of the first shaft S1 is fixed.

[0013] Next, as shown in Fig. 9(c), the second shaft S2 is fitted into the main body vertical groove 101b of the main body 101. Next, as shown in Fig. 9(d), the second shaft S2 is also fitted into the second cover vertical groove 103b, and as shown in Fig. 8, the left side surface 103a of the second cover part 103 is overlapped with the right side surface 101a of the main body 101, and the pair of bolts B2 are inserted into the pair of bolt insertion holes 103c1 and the pair of bolt holes 101a1 and screwed together. As a result, as shown in Fig. 9(d), the second cover part 103 and the main body 101 are attached and fixed with the second shaft S2 sandwiched therebetween, and the position of the second shaft S2 is fixed.

[0014] Therefore, the first shaft S1 and the second shaft S2 can be fixed in a perpendicular state using the connecting member 100 as described above.

[0015] Incidentally, when attempting to connect the first shaft S1 and the second shaft S2 in a lattice pattern as shown in Fig. 7(a) to fix them orthogonally, they will be fixed using a plurality of connecting members 100 as shown in Fig. 7(b). Therefore, in such a case, they are connected in the following manner.

[0016] First, as shown in FIG. 10(a), a plurality of main bodies 101 (three in the figure) are prepared. Then, the first shaft S1 is fitted into the main body lateral groove 101d of the main body 101. Next, as shown in FIG. 10(b), the first shaft S1 is also fitted into the first cover lateral groove 102b. Then, as shown in FIG. 8, the right side surface 102a of the first cover part 102 is overlapped with the left side surface 101c of the main body 101, and a pair of bolts B1 are inserted into the pair of bolt insertion holes 102a1 and the pair of bolt holes 101b1 and screwed together. As a result, as shown in FIG. 10(b), the plurality of first cover parts 102 and the plurality of main bodies 101 are attached and fixed with the first shaft S1 sandwiched therebetween, and the position of the first shaft S1 is fixed.

[0017] Next, it is desired to fit the second shaft S2 into the main body vertical groove 101b shown in Fig. 10(b) as shown in Fig. 11(a). However, when working with multiple main bodies 101, the main bodies 101 are placed on a flat surface such as the floor during the work. Therefore, in this state, it is not possible to fit the second shaft S2 into the main body vertical groove 101b shown in Fig. 10(b) as shown in Fig. 11(a).

[0018] 10(b), that is, after turning it over to the state shown in Fig. 11(b), the second shaft S2 is fitted into the main body vertical groove 101b. After that, although not shown, as explained above, by screwing the second cover part 103 to the main body 101, the first shaft S1 and the second shaft S2 can be connected in a lattice pattern as shown in Fig. 7(a).

[0019] However, this method has the problem that the larger the lattice frame, the more difficult the inversion work becomes, and it requires a lot of time and effort, resulting in very poor workability.

[0020] Furthermore, when fixing the first shaft S1 and the second shaft S2 to the connecting member 100 as described above, it is necessary to fix them using bolts B1 and B2 from both the left and right sides of the main body 101, as shown in Figure 8. Therefore, when a lattice frame in which the first shaft S1 and the second shaft S2 are fixed perpendicularly is installed against a wall, as shown in Figure 7(b), it is very difficult to adjust the width of the lattice frame and to remove or add the first shaft S1 and / or the second shaft S2, resulting in a problem of very poor workability.

[0021] In view of the above problems, the present invention has an object to provide a connecting member that can significantly improve workability. [Means for solving the problem]

[0022] The above object of the present invention can be achieved by the following means: Note that the parentheses indicate reference symbols of embodiments to be described later, but the present invention is not limited to these.

[0023] The connecting member according to claim 1 comprises a base portion (2), a support part (3) rotatably provided on one side of the base part (2); a cover portion (4) rotatably provided on one side of the support portion (3), By rotating the support part (3), the first support column (the first shaft S1 or the second shaft S2) is sandwiched between the support part (3) and the base part (2) to be fixed, and further, By rotating the cover part (4), the second support (second shaft S2 or first shaft S1) is sandwiched and fixed between the cover part (4) and the support part (3), thereby fixing the first support and the second support in a perpendicular state.

[0024] The connecting member according to claim 2 is the connecting member (1) according to claim 1, wherein the base portion (2) and the support portion (3) are each provided with a first groove portion (base vertical groove 2d, support portion vertical groove 3d) so that the first support column (first shaft S1 or second shaft S2) can be sandwiched therebetween; The cover part (4) and the support part (3) are each characterized by having a second groove part (support part horizontal groove 3h, cover part horizontal groove 4d) so that the second support (second shaft S2 or first shaft S1) can be sandwiched therein.

[0025] The connecting member according to claim 3 is the connecting member (1) according to claim 1 or 2, wherein the base portion (2) and the support portion (3) are each provided with a first bolt hole (base bolt hole 2g, first support portion bolt hole 3k) so that when the first support column (first shaft S1 or second shaft S2) is sandwiched between the base portion (2) and the support portion (3), the first support column can be fixed with a first bolt (bolt B3); The cover portion (4) and the support portion (3) are each provided with a second bolt hole (cover portion bolt hole 4h, second support portion bolt hole 3l) so that when the second support column (second shaft S2 or first shaft S1) is sandwiched between the cover portion (4) and the support portion (3), the second support column can be fixed with a second bolt (bolt B4), The first bolt (bolt B3) and the second bolt (bolt B4) are characterized in that the first bolt (bolt B3) is inserted into the first bolt hole (base bolt hole 2g, first support part bolt hole 3k) from the same direction, and the second bolt (bolt B4) is inserted into the second bolt hole (cover part bolt hole 4h, second support part bolt hole 3l).

[0026] A connecting member according to a fourth aspect of the present invention is the connecting member (1) according to the third aspect of the present invention, wherein the cover portion (4) is provided with a relief hole (4i) in addition to the second bolt hole (cover portion bolt hole 4h), The first bolt (bolt B3) can be operated through the escape hole (4i). [Effects of the Invention]

[0027] Next, the effects of the present invention will be described with reference to the drawings. Note that the reference symbols in parentheses are those of the embodiments described below, but the present invention is not limited to these.

[0028] According to the invention of claim 1, by rotating the support part (3), the first support column (first shaft S1 or second shaft S2) is sandwiched between the support part (3) and the base part (2) and fixed. Then, by rotating the cover part (4), the second support column (second shaft S2 or first shaft S1) is sandwiched between the cover part (4) and the support part (3) and fixed. In this way, the first support column and the second support column are fixed in an orthogonal state.

[0029] Therefore, this eliminates the need for the conventional inversion work, thereby significantly improving workability.

[0030] According to the invention of claim 2, the first support column (first shaft S1 or second shaft S2) and the second support column (second shaft S2 or first shaft S1) can be clamped simply and easily.

[0031] According to the invention of claim 3, the first bolt (bolt B3) and the second bolt (bolt B4) are inserted from the same direction, with the first bolt (bolt B3) being inserted into the first bolt hole (base bolt hole 2g, first support portion bolt hole 3k), and the second bolt (bolt B4) being inserted into the second bolt hole (cover portion bolt hole 4h, second support portion bolt hole 3l). This facilitates the width adjustment of the lattice frame and the removal or addition of the first support column (first shaft S1 or second shaft S2) and / or the second support column (second shaft S2 or first shaft S1). This further significantly improves workability.

[0032] According to the invention of claim 4, since the position can be adjusted from the same direction while maintaining the fixed state of either the first support column (first shaft S1 or second shaft S2) or the second support column (second shaft S2 or first shaft S1), it becomes easier to adjust the width of the lattice frame and to remove or add the first support column (first shaft S1 or second shaft S2) and / or the second support column (second shaft S2 or first shaft S1).This makes it possible to further significantly improve workability.

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, a connecting member according to one embodiment of the present invention will be described in detail with reference to the drawings. In the following description, when directions such as up, down, left, and right are indicated, they refer to up, down, left, and right when viewed from the front of the illustration.

[0035] <Outline of connecting members> The connecting member according to this embodiment can significantly improve workability. Specifically, as shown in Fig. 1, the connecting member 1 is mainly composed of a base portion 2, a support portion 3, and a cover portion 4. Each component will be described in detail below.

[0036] <Explanation of the base part> As shown in Fig. 2, the base portion 2 is formed in a substantially rectangular shape, and a concave base vertical groove 2d is provided in the center of the front end face 2a, extending from the upper end face 2b to the lower end face 2c of the base portion 2. As shown in Fig. 2, a pair of semicircular base rotation mounting portions 2f are integrally provided on the left side face 2e of the base portion 2, protruding outward at a distance from each other. Note that, as shown in Fig. 2, a through-hole 2f1 is provided in the center of the base rotation mounting portion 2f, penetrating it in the vertical direction.

[0037] 2, a pair of base bolt holes 2g are provided at a distance from each other so as to be diagonally positioned on the front end surface 2a of the base portion 2, and extend through the base portion 2 in the front-to-rear direction (from the front end surface 2a to the rear end surface 2h of the base portion 2). The pair of base bolt holes 2g are threaded holes into which bolts can be inserted.

[0038] <Explanation of support parts> As shown in Fig. 2, the support part 3 is formed in a substantially rectangular shape, and a concave support part vertical groove 3d is provided in the center of the front end face 3a, extending from the upper end face 3b to the lower end face 3c of the support part 3. As shown in Fig. 2, a concave support part horizontal groove 3h (see also Fig. 3(c)) is provided in the center of the rear end face 3e, extending from the left side face 3f to the right side face 3g of the support part 3. Furthermore, as shown in Fig. 2, a pair of semicircular first support part rotatable mounting parts 3i are integrally provided on the right side face 3g of the support part 3, protruding outward at a distance from each other. As shown in Fig. 2, a through-hole 3i1 is provided in the center of the first support part rotatable mounting part 3i, penetrating vertically.

[0039] Furthermore, as shown in Fig. 2, a pair of semicircular second support part rotation mounting parts 3j are integrally provided at a distance from each other and protrude outward from the upper end surface 3b of the support part 3. As shown in Fig. 2, a through-hole 3j1 is provided in the center of the second support part rotation mounting part 3j, penetrating it in the left-right direction.

[0040] Meanwhile, as shown in FIG. 2, a pair of first support bolt holes 3k are provided diagonally at a distance from each other in the front end surface 3a of the support part 3, and extend in the front-to-rear direction in the figure (from the front end surface 3a of the support part 3 to the rear end surface 3e of the support part 3). Furthermore, as shown in FIG. 2, in addition to the pair of first support bolt holes 3k, a pair of second support bolt holes 3l are provided diagonally at a distance from each other in the front end surface 3a of the support part 3, and extend in the front-to-rear direction in the figure (from the front end surface 3a of the support part 3 to the rear end surface 3e of the support part 3). The pair of first support bolt holes 3k are relief holes through which bolts can be inserted. The pair of second support bolt holes 3l are threaded holes through which bolts can be inserted.

[0041] <Cover explanation> As shown in Fig. 2, the cover part 4 is formed in a substantially rectangular shape, and a concave cover part lateral groove 4d (see also Fig. 3(c)) is provided in the center of the rear end face 4a, extending from the left side face 4b to the right side face 4c of the cover part 4. As shown in Fig. 2, a pair of semicircular cover part rotation mounting parts 4f are integrally provided on the lower end face 4e of the cover part 4, protruding outward at a distance from each other. As shown in Fig. 2, a through-hole 4f1 is provided in the center of the cover part rotation mounting part 4f, penetrating in the left-right direction.

[0042] Furthermore, as shown in FIG. 2, a pair of cover portion bolt holes 4h are provided in the front end surface 4g of the cover portion 4 so as to be diagonally spaced apart and penetrate in the front-to-rear direction in the figure (from the front end surface 4g of the cover portion 4 toward the rear end surface 4a of the cover portion 4). Furthermore, as shown in FIG. 2, in addition to the pair of cover portion bolt holes 4h, a pair of relief holes 4i are provided in the front end surface 4g of the cover portion 4 so as to be diagonally spaced apart and penetrate in the front-to-rear direction in the figure (from the front end surface 4g of the cover portion 4 toward the rear end surface 4a of the cover portion 4). Note that the pair of cover portion bolt holes 4h are relief holes that allow the head of a bolt to be inserted by sinking it. The pair of relief holes 4i are also relief holes that allow the head of a bolt to be inserted.

[0043] The above description relates to the configuration of the connecting member 1.

[0044] <Explanation of assembly of connecting parts> Thus, the connecting member 1 configured as described above is assembled as follows. That is, as shown in Fig. 2, the base rotation mounting portion 2f of the base portion 2 and the first support portion rotation mounting portion 3i of the support portion 3 are overlapped, and a rod-shaped first pin 5 is inserted into the through-hole 2f1 of the base rotation mounting portion 2f and the through-hole 3i1 of the first support portion rotation mounting portion 3i. As a result, the support portion 3 is rotatably mounted on the left side surface 2e of the base portion 2 (see Fig. 2) as shown in Fig. 1.

[0045] 2, the second support part rotation mounting portion 3j of the support part 3 and the cover part rotation mounting portion 4f of the cover part 4 are overlapped, and a rod-shaped second pin 6 is inserted into the through-hole 3j1 of the second support part rotation mounting portion 3j and the through-hole 4f1 of the cover part rotation mounting portion 4f. As a result, the cover part 4 is rotatably mounted on the upper end surface 3b of the support part 3 (see FIG. 2) as shown in FIG.

[0046] Therefore, the connecting member 1 is assembled in the manner described above.

[0047] <Explanation of examples of use of connecting members> Next, a method for fixing the first shaft S1 and the second shaft S2 shown in FIG. 7 in a perpendicular state using the connecting member 1 assembled as described above will be described.

[0048] First, the second shaft S2 is fitted into the base vertical groove 2d of the base portion 2, as shown in FIG. 3(a).

[0049] Next, as shown in FIG. 3(b), when the support part 3 is rotated toward the base part 2 (in the direction of arrow Y1) around the first pin 5 as a base point, the second shaft S2 can be fitted into the support part vertical groove 3d of the support part 3 as well, as shown in FIG. 3(c). In this state, a pair of bolts B3 shown in FIG. 3(c) are inserted into the pair of first support part bolt holes 3k and into the base bolt holes 2g shown in FIG. 2 and screwed in place. As a result, as shown in FIG. 3(c), the base part 2 and the support part 3 are attached and fixed with the second shaft S2 sandwiched between them, and the position of the second shaft S2 is fixed.

[0050] Next, as shown in FIG. 4(a), the first shaft S1 is fitted into the support portion lateral groove 3h of the support portion 3. In this state, as shown in FIG. 4(a), when the cover portion 4 is rotated toward the support portion 3 (in the direction of arrow Y2) around the second pin 6 as a base point, the first shaft S1 can also be fitted into the cover portion lateral groove 4d of the cover portion 4 as shown in FIG. 4(b). Thereafter, a pair of bolts B4 shown in FIG. 4(b) are inserted into the pair of cover portion bolt holes 4h and into the second support portion bolt holes 3l shown in FIG. 2 and screwed in place. As a result, as shown in FIG. 4(b), the support portion 3 and the cover portion 4 are attached and fixed with the first shaft S1 sandwiched therebetween, and the position of the first shaft S1 is fixed.

[0051] Thus, by doing this, the first shaft S1 and the second shaft S2 can be fixed in a perpendicular state using the connecting member 1, as shown in FIG.

[0052] Therefore, by using the connecting member 1 of the present embodiment as described above, it is not necessary to perform the conventional inversion work, and therefore workability can be improved significantly.

[0053] Furthermore, in the present embodiment, an example has been shown in which the second shaft S2 is fixed by fitting it into the base vertical groove 2d of the base portion 2 and the support portion vertical groove 3d of the support portion 3, and the first shaft S1 is fixed by fitting it into the support portion horizontal groove 3h of the support portion 3 and the cover portion horizontal groove 4d of the cover portion 4, but this is not limiting, and the first shaft S1 can also be fitted into the base vertical groove 2d of the base portion 2 and the support portion vertical groove 3d of the support portion 3, and the second shaft S2 can be fitted into the support portion horizontal groove 3h of the support portion 3 and the cover portion horizontal groove 4d of the cover portion 4. In other words, the connecting member 1 according to the present embodiment has the advantage that it can be used without having to determine its orientation or position.

[0054] On the other hand, in this embodiment, as described above, both the pair of bolts B3 shown in Fig. 3(c) and the pair of bolts B4 shown in Fig. 4(b) can be inserted from the same direction. Therefore, even if a lattice-shaped frame in which the first shaft S1 and the second shaft S2 are fixed perpendicularly is installed on the wall K as shown in Fig. 5, both the pair of bolts B3 shown in Fig. 3(c) and the pair of bolts B4 shown in Fig. 4(b) can be inserted from the same direction, which has the advantage of facilitating the width adjustment of the lattice-shaped frame and the removal and addition of the first shaft S1 and / or the second shaft S2. This further significantly improves workability.

[0055] Furthermore, in this embodiment, the cover portion 4 is provided with relief holes 4i as shown in FIG. 2. As shown in FIG. 6(a), the relief holes 4i allow access to a pair of bolts B3. That is, the pair of bolts B3 can be operated via the relief holes 4i. Therefore, to adjust the position of the second shaft S2, the pair of bolts B3 can be operated via the relief holes 4i shown in FIG. 6(a) to loosen the fastening between the base portion 2 and the support portion 3. This allows the second shaft S2 to be moved in the direction of arrow Y3 shown in FIG. 6(a), thereby enabling the position of the second shaft S2 to be adjusted. Note that the first shaft S1 remains fixed to the support portion 3 and the cover portion 4 by a pair of bolts B4 as shown in FIG. 6(a).

[0056] On the other hand, to adjust the position of the first shaft S1, a pair of bolts B4 shown in Fig. 6(b) can be operated to loosen the connection between the support part 3 and the cover part 4. This allows the first shaft S1 to be moved in the direction of arrow Y4 shown in Fig. 6(b), thereby enabling the position of the first shaft S1 to be adjusted. Note that the second shaft S2 remains fixed to the base part 2 and the support part 3 by a pair of bolts B3 as shown in Fig. 6(b).

[0057] Therefore, by providing the above-described relief holes 4i, it is possible to adjust the position from the same direction while maintaining the fixed state of either the first shaft S1 or the second shaft S2, which has the advantage of facilitating the work of adjusting the width of the lattice frame and the work of removing or adding the first shaft S1 and / or the second shaft S2. As a result, it is possible to further significantly improve workability.

[0058] <Description of Modifications> It should be noted that the shapes and the like shown in this embodiment are merely examples, and various modifications and changes are possible within the scope of the gist of the present invention as set forth in the claims. For example, the shapes of the base part 2, the support part 3, and the cover part 4 shown as examples in this embodiment are merely examples, and can be changed into various shapes.

[0059] In addition, in the present embodiment, an example has been shown in which the second shaft S2 is fixed by fitting it into the base vertical groove 2d of the base portion 2 and the support portion vertical groove 3d of the support portion 3, and the first shaft S1 is fixed by fitting it into the support portion lateral groove 3h of the support portion 3 and the cover portion lateral groove 4d of the cover portion 4, but this is not limiting and any method of sandwiching them is acceptable. However, as described above, the method of fitting them into the base vertical groove 2d of the base portion 2 and the support portion vertical groove 3d of the support portion 3, and into the support portion lateral groove 3h of the support portion 3 and the cover portion lateral groove 4d of the cover portion 4 is preferred. This is because the first shaft S1 and the second shaft S2 can be sandwiched simply and easily.

[0060] In addition, in this embodiment, a method of fixing the first shaft S1 and the second shaft S2 in a perpendicular state has been described, but this is not limited to the first shaft S1 and the second shaft S2, and can be adapted to various supports such as pipes. [Explanation of symbols]
