DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Fig. 1 is a perspective view showing a state in which T1 and T2 are connected using a component connecting fitting P1 according to a first embodiment of the present invention, and Figs. 2 to 5 are diagrams for explaining the component connecting fitting P1 of the first embodiment. As shown in these figures, the component connecting fitting P1 of the first embodiment is used when connecting a first connection target component T1 and a second connection target component T2, which are connection target components such as beams.

[0030] The component connecting fitting P1 of this first embodiment comprises, as basic components, a first clamp 11 for holding (clamping) a first connection target component T1, a second clamp 12 for holding (clamping) a second connection target component T2, and a metal rivet 13 as a clamp connecting device for connecting both clamps 11, 12. Furthermore, in this embodiment, the first and second clamps 11, 12 both have the same configuration, and each comprises a metal clamp body 2 and a metal fastener 5.

[0031] The clamp body 2 has a U-shaped configuration formed integrally with both side plate parts 3, 3 arranged approximately in parallel and an intermediate plate part 4 connecting the base ends of the both side plate parts 3. This clamp body 2 is configured so that connection target members T1, T2 can be accommodated in a U-shaped recess 20 formed between the both side plate parts 3, and is configured so that the connection target members T1, T2 accommodated in the U-shaped recess 20 can be clamped by being sandwiched between the both side plate parts 3, as described below.

[0032] Both side edges and tip edges of both side plate parts 3 of clamp body 2 and both side edges of intermediate plate part 4 are bent inward to form bent hem parts 31, 41. Furthermore, the bent hem parts 31 of both side edges of both side plate parts 3 are formed with sawtooth notches to form anti-slip parts 39.

[0033] The intermediate plate portion 4 is formed with through holes 42 penetrating the intermediate plate portion 4. A total of five through holes 42 are provided, one in the center and four around it, in other words, the five through holes 42 are arranged like the dot symbol of the number "5" on a die.

[0034] Each of the side plate parts 3 also has one in the center and four around it, for a total of five through holes 32, and similarly to the above, the five through holes 32 are arranged like the dot symbol of the number "5" on a die. Between the side plate parts 3, the five through holes 32 are arranged facing each other.

[0035] A countersunk portion 33 is formed on the outer surface of the side plate portions 3, closer to the tip side than the through hole 32. A square support hole 34 is formed in the countersunk portion 33 of one of the side plate portions 3. Furthermore, the other side plate portion 3 is formed with a notch 35 that extends from the countersunk portion 33 to the tip edge and opens to the tip side.

[0036] 4 and 5, in the clamp body 2 of this embodiment, in a natural state where it is not constrained by the fastener 5 as described later, the distance between the two side plates 3 is gradually increased from the base end to the tip end. In other words, the opening angle of the two side plates 3 with respect to the intermediate plate 4 is greater than 90°, and the two side plates 3 are arranged in an inverted V-shape or a tip-opening shape that opens slightly outward.

[0037] On the other hand, the fastener 5 includes a bolt 51 and a nut 55 into which the bolt 51 is screwed.

[0038] The nut 55 is composed of a bag-shaped long nut and has a tubular portion 56 with a female thread engraved on its inner surface, and a large-diameter anti-slip portion 57 formed at the end (non-receiving end) of the tubular portion 56 opposite the end that receives the bolt 51.

[0039] The cylindrical portion 56 of the nut 55 is inserted into the support hole 34 from the outer surface side of one of the side plate portions 3 of the clamp body 2, and the retaining portion 57 is disposed in the counterbore portion 33, thereby assembling the nut 55 to one of the side plate portions 3. In this assembled state, the cylindrical portion 56 of the nut 55 is supported in a swingable manner in the support hole 34, and the nut 55 is configured to be swingable along the notch direction of the notch portion 35 of the other side plate portion 3 (the up and down direction in FIG. 4). Furthermore, the retaining portion 57 of the nut 55 is configured to be reliably accommodated in the counterbore portion 33, and the end face of the retaining portion 57 does not protrude outward from the outer surface of the one side plate portion 3.

[0040] Bolt 51 has shank 52 with a male thread engraved on its outer circumferential surface, and large-diameter head 53 formed on the end (non-insertion end) opposite the insertion end of shank 52. Shank 52 of bolt 51 is inserted into cylindrical portion 56 of nut 55, and the male thread of shank 52 is screwed into the female thread of cylindrical portion 56, thereby assembling bolt 51 to nut 55 and forming fastener 5.

[0041] The support hole 34 in one of the side plate portions 3 is formed to a size that allows the shaft portion 52 of the bolt 51 and the tubular portion 56 of the nut 55 to pass through, but does not allow the head portion 53 of the bolt 51 and the anti-slip portion 57 of the nut 55 to pass through.

[0042] In this fastener 5, when the bolt 51 is loosened and the nut 55 is swung together with the bolt 51 as described above, the shaft 52 of the bolt 51 can be inserted into and engaged with the notch 35 of the other side plate 3, or removed from the notch 35. The fastener 5 is thus supported on one side plate 3 so as to be swung, and the other end of the fastener 5 (the non-inserted end of the shaft 52) ​​can be engaged and disengaged with the notch 35 based on the swinging operation. Furthermore, when the bolt 51 is released from the notch 35, the fastener 5 is moved overall toward the support hole 34 as described below, and the tip sides of the both side plate parts 3 in the U-shaped recess 20 are opened (see FIG. 6B).

[0043] In this embodiment, when the shaft portion 52 of the bolt 51 is securely received within the cutout portion 35 , the end face of the head portion 53 is configured not to protrude outward from the outer surface of the other side plate portion 3 .

[0044] Furthermore, when the bolt 51 is rotated in the tightening direction while the bolt 51 is engaged in the notch 35, the overall length of the fastener 5 becomes shorter, and accordingly, both side plate portions 3 close inward against their elastic force so as to narrow the gap, and the connection target members T1, T2 contained in the U-shaped recess 20 are clamped by both side plate portions 3. On the other hand, when the bolt 51 is rotated in the loosening direction, the overall length of the fastener 5 becomes longer, and accordingly, both side plate portions 3 open outward against their elastic restoring force so as to widen the gap, and the clamping by both side plate portions 3 of the connection target members T1, T2 contained in the U-shaped recess 20 is released.

[0045] In this manner, in this embodiment, the spacing between the two side plate portions 3 can be adjusted based on the rotation operation of the bolt 51, and this adjustment makes it possible to clamp or release the connection target members T1, T2 arranged between the two side plate portions 3.

[0046] In addition, in this embodiment, a long nut is used as the nut 55 of the fastener 5, so regardless of the amount by which the bolt 51 is screwed into the nut 55, for example, even if the bolt 51 is screwed into the nut 55 a large amount, the insertion side end of the bolt 51 will not penetrate through the non-receiving side end of the nut 55 and be positioned outside. Therefore, it is possible to prevent the end of the fastener 5 from protruding outward from the outer surfaces of the both side plate portions 3.

[0047] In this embodiment, the nut 55 of the fastener 5 is provided on one side plate portion 3, and the bolt 51 is provided on the other side plate portion 3, but this is not limited to this, and in the present invention, the bolt 51 may be provided on one side plate portion 3, and the nut 55 may be provided on the other side plate portion 3.

[0048] As described above, the first clamp 11 and the second clamp 12 have the same configuration as each other, including the clamp body 2 and the fastener 5. The two clamps 11, 12 are connected by a rivet 13, which serves as a clamp connector, as described below.

[0049] First, the outer surface of the intermediate plate portion 4 of the first clamp 11 and the outer surface of the intermediate plate portion 4 of the second clamp 12 are arranged to face each other and overlap each other. In this case, an axis perpendicular to the facing surfaces of the intermediate plate portions 4, 4 of both clamps 11, 12 and passing through the center of the intermediate plate portions 4, 4 is set as a central axis X (see FIG. 3), and the intermediate plate portions 4, 4 are fixed to each other by riveting in a twisted state in which the first clamp 11 is shifted in phase by 90° from the second clamp 12 about this central axis X. In other words, the first clamp 11 and the second clamp 12 are fixed to each other by riveting in a state in which the opening direction D1 of both end openings provided at both ends of the U-shaped recess 20 of the first clamp 11 and the opening direction D2 of both end openings provided on both sides of the U-shaped recess 20 of the second clamp 12 are arranged to be perpendicular to each other.

[0050] When riveting, the rivets 13 are inserted into two of the diagonally arranged through holes 32 out of five through holes 32 provided in the intermediate plate portions 4, 4, and the ends of the insertion sides of the rivets 13 are crimped to fix them in place. In this manner, the first clamp 11 is fixed in a state where it is twisted 90° relative to the second clamp 12, thereby forming the component connecting fitting P1 of the first embodiment.

[0051] In the member connecting fitting P1 of the first embodiment, unlike the third embodiment described below, the first clamp 11 cannot be rotated about the central axis X relative to the second clamp 12.

[0052] In the component connecting fitting P1 having this configuration, the opening direction D1 of both end openings provided on both sides of the U-shaped recess 20 of the first clamp 11 and the opening direction D2 of both end openings provided on both sides of the U-shaped recess 20 of the second clamp 12 are arranged perpendicular to each other. Furthermore, the opening directions D1 and D2 are each arranged perpendicular to the central axis X.

[0053] In this first embodiment, when the first connection target member T1 is connected using the member connecting fitting P1, as shown in FIG. 6A, in a state where the bolt 51 of the fastener 5 in the first clamp 11 is loosened, the fastener 5 is swung outward (upper side in FIG. 6A) to remove the bolt 51 from the notch 35. Next, as shown in FIG. 6B, the fastener 5 is moved toward the one side plate 3 while being inserted into the support hole 34 of the one side plate 3, and the bolt head 53 of the fastener 5 is moved to the position of the support hole 34 of the one side plate 3. This opens the tip side (upper side in FIG. 6B) of both side plate parts 3 in the U-shaped recess 20 of the first clamp 11. In this state, the bolt head 53 is hooked to the peripheral portion of the support hole 34 of the one side plate part 3, so that the fastener 5 can be reliably prevented from falling off the clamp body 2.

[0054] Next, the first connection target member T1 is accommodated in the U-shaped recess 20 of the first clamp 11 from its open tip end, and then the fastener 5 is pulled out toward the other side plate 3, and the bolt head 53 is inserted into the notch 35 of the other side plate 3 and latched. Thereafter, the bolt 51 is tightened to narrow the width of both side plates 3, and the first connection target member T1 is clamped by both side plates 3. This allows the first connection target member T1 to be connected and fixed to the first clamp 11 of the member connecting fitting P1.

[0055] Needless to say, the second clamp 12 clamps the second connection target member T2 in a similar manner.

[0056] When the two connection target members T1, T2 are connected in this manner using the member connecting fitting P1, the two connection target members T1, T2 are arranged perpendicular to each other when viewed along the central axis X, as shown in FIG.

[0057] On the other hand, when releasing the connection between the connection target members T1, T2, the bolt 51 is loosened, the side plate portions 3 are widened, the bolt 51 is removed from the notch portion 35, and the fastener 5 is inserted into the support hole 34 while being moved toward one of the side plate portions 3 to engage the bolt head 53 in the support hole 34. In this manner, the tip side of the U-shaped recesses 20 of the clamps 11, 12 can be opened, and the connection target members T1, T2 can be removed from the U-shaped recesses 20 through the open portion.

[0058] In the component connecting fitting P1 of this embodiment configured as described above, the two connection target components T1, T2 can be easily connected with high positional accuracy simply by accommodating the two connection target components T1, T2 in the U-shaped recesses 20 of both clamps 11, 12 and tightening the bolt 51.

[0059] In addition, in this embodiment, when both clamps 11, 12 are in their natural state where the constraint by the fastener 5 is released, that is, when the bolt 51 is removed from the cutout portion 35 and the fastener 5 is moved toward the support hole 34 to open the tip side of the U-shaped recess 20, the side plate portions 3 are open in a forward-opening manner, so that the connection target members T1, T2 can be easily inserted and removed from the U-shaped recess 20 between the side plate portions 3, making the connection work of the connection target members T1, T2 even easier.

[0060] Furthermore, when fastener 5 is moved toward support hole 34 and the tip side of U-shaped recess 20 is opened, bolt head 52 of fastener 5 hooks onto the periphery of support hole 34, preventing fastener 5 from falling off from clamp body 2. Since fastener 5 can be prevented from falling off in this way, it is possible to reliably prevent inconveniences such as having to reattach fastener 5 or losing fastener 5, improving convenience.

[0061] Furthermore, in the component connecting fitting P1 of this first embodiment, a long nut is used as the nut 55 of the fastener 5, so regardless of the amount of tightening of the bolt 51, the insertion end of the bolt 51 will not be positioned so as to protrude through the nut 55. This prevents a problem in which the protruding bolt end would interfere with the connection of the connection target components T1, T2, and makes it possible to perform the connection work of the connection target components T1, T2 even smoother.

[0062] Furthermore, in this embodiment, a countersink portion 33 is formed on the outer surfaces of both side plate portions 3 so that the head 53 of the bolt 51 and the anti-slip portion 57 of the nut 55 are securely accommodated within the countersink portion 33. This prevents the bolt head 53 and the nut anti-slip portion 57 from protruding from the outer surface of the clamp body 2. This also makes it possible to more reliably prevent problems such as the protruding portions interfering with the connection of the connection target members T1, T2, and makes it possible to perform the connection work of the connection target members T1, T2 even smoother.

[0063] Furthermore, in the component connecting fitting P1 of this first embodiment, the upper edge 34a of the inner peripheral edge of the square-hole-shaped support hole 34, which supports the fastener 5 so that it can swing freely, is formed in an arc shape (see Figures 2 and 5, etc.), which allows the fastener 5 to swing smoothly and facilitates the operation of attaching and detaching the fastener 5 to the cutout portion 35, thereby facilitating the component connecting work.

[0064] <Second embodiment> Fig. 7 is a perspective view showing a component connecting fitting P2 according to a second embodiment of the present invention. As shown in the figure, the component connecting fitting P2 of this second embodiment differs from the component connecting fitting P1 of the first embodiment in that, whereas in the component connecting fitting P1 of the first embodiment, the first clamp 11 is fixed in a twisted state with a phase shift of 90° around the central axis X relative to the second clamp 12, in the component connecting fitting P2 of the second embodiment, the first clamp P1 is fixed in a non-twisted state with the phases about the central axis X aligned relative to the second clamp P2.

[0065] In the member connecting fitting P2 of the second embodiment, the first clamp 11 is disposed in a non-twisted state with respect to the second clamp 12, so that the opening direction D1 of both end openings of the U-shaped recess 20 in the first clamp 11 and the opening direction D2 of both end openings of the U-shaped recess 20 in the second clamp 12 are disposed parallel to each other. Therefore, the first connection target member T1 held by the first clamp 11 and the second connection target member T2 held by the second clamp 12 can be disposed parallel to each other.

[0066] In the member connecting fitting P1 of the second embodiment, similarly to the first embodiment, the first clamp 11 cannot be rotated about the central axis X relative to the second clamp 12.

[0067] The other configuration of the member connecting fitting P2 of the second embodiment is similar to that of the member connecting fitting P1 of the first embodiment described above, so the same or corresponding parts are given the same reference numerals and repeated explanations will be omitted.

[0068] The member connecting fitting P2 of the second embodiment can also provide the same effects as those of the first embodiment.

[0069] <Third embodiment> Fig. 8A is a front view of a component connecting fitting P3 according to a third embodiment of the present invention, and Fig. 8B is an exploded view thereof. As shown in both figures, the component connecting fitting P3 of this third embodiment differs from the component connecting fittings P1, P2 of the first and second embodiments in that, whereas in the component connecting fittings P1, P2 of the first and second embodiments, the first clamp P1 is fixed relative to the second clamp P2 in a state in which rotation about the central axis X is restricted, in the component connecting fitting P3 of this third embodiment, the first clamp P1 is attached to the second clamp P2 so as to be rotatable about the central axis X.

[0070] That is, in this third embodiment, a rotating shaft plate 14 is disposed on the inner surface of the overlapping intermediate plate portions 4 of both clamps 11, 12, and one rivet 13 is inserted through a central hole of the rotating shaft plate 14 and a central through-hole 42 of the intermediate plate portion 4 and is fixed by crimping. In this way, the first clamp 11 is attached to the second clamp 12 so as to be relatively rotatable about the axis of the rivet 13 (central axis X).

[0071] The other configuration of the member connecting fitting P3 of the third embodiment is similar to that of the member connecting fittings P1, P2 of the first and second embodiments described above, so the same or corresponding parts are given the same reference numerals and repeated explanations will be omitted.

[0072] In the component connecting fitting P3 of this third embodiment, the first clamp 11 is configured to be freely rotatable relative to the second clamp 12, so that the first connection target component T1 held by the first clamp 11 can be freely rotatably connected to the second connection target component T2 held by the second clamp 12, and the two connection target components T1, T2 can be connected in a variety of forms.

[0073] The member connecting fitting P3 of the third embodiment can also provide the same effects as those of the first and second embodiments.

[0074] <Modification> In the above embodiment, the connection target members T1 and T2 are described as square timbers, but the connection target members are not particularly limited in the present invention, and connection target members other than square timbers may be connected. For example, round bars, plate materials, etc. may be connected, and further, members other than wood-based connection target members such as wood, for example, connection target members made of plastic or metal may be connected.

[0075] In the above embodiment, a case has been described in which a long nut is used as the nut 55 of the fastener 5, but this is not limited thereto, and in the present invention, a general nut having a short axial length may be used as the nut.

[0076] In the above embodiment, the bolt 51 of the fastener 5 has a male thread engraved along almost the entire length of the shaft 52. However, this is not limited to this. In the present invention, as shown in FIG. 9, the bolt 51 may have a knurled structure in which a mesh-like knurl 52a is provided on a part of the shaft 52 (the part close to the head 53). [Industrial Applicability]

[0077] The member connecting fitting of the present invention can be suitably used when connecting and fixing members to be connected, such as beams, to each other when assembling or stacking the members to be connected into a predetermined shape. [Explanation of symbols]
