And a second connecting portion for pivotally connecting the third engaging member around an axis parallel to the reference plane at different positions in the longitudinal direction of the member, and reinforcing to suppress bending deformation of the base member Department.

  According to this configuration, the first engagement member and the second engagement member are connected to the first connection portion of the base member so as to be relatively rotatable along the reference plane, and the second connection portion of the base member is connected to the second connection portion. The three engaging members are coupled so as to be relatively rotatable so as to intersect the reference plane. Therefore, the first rod-shaped body, the second rod-shaped body, and the third rod-shaped body that intersect with each other can be connected to each other while adjusting the intersecting angle by using one base member as an intermediary. The first engaging member, the second engaging member, and the third engaging member are all configured by elastically deformable spring plate members, and are respectively engaged and held with respect to the corresponding rod-like bodies by elastic restoring force.

The second engagement member 40 is engaged and held with respect to the brace bolt 82 </ b> A by the pair of notch-shaped recesses 44. It should be noted that the two second engaging members 40 arranged in an overlapping manner have an interval between the pair of notch-shaped recesses 44 in each of them in order to avoid interference between the two brace bolts 82A to be engaged and held. Different lengths are formed so as to be different from each other (see FIG. 7).

  The third engagement member 50 also has the same basic configuration as the first engagement member 30 and the second engagement member 40. In other words, the third engagement member 50 is configured by a belt-plate-like spring plate member that can be elastically deformed. The third engaging member 50 includes a central plate portion 51 having a hole portion 51a, a pair of inclined plate portions 53 having a notch-shaped concave portion 54 and a locking claw 55, and a pair of operation plate portions 57. I have. The third engaging member 50 is pivotally connected at the second connecting portion 25. The third engagement member 50 is engaged and held with respect to the brace bolt 82 </ b> B by the pair of notch-shaped recesses 54.

  In the cross connector 1 of the present embodiment, the first engagement member 30 and the two second engagement members 40 are connected to the first connection portion 22 of the base member 20 so as to be relatively rotatable along the reference plane P. At the same time, the third engaging member 50 is connected to the second connecting portion 25 so as to be relatively rotatable so as to intersect the reference plane P. Therefore, one suspension bolt 81, two brace bolts 82A, and one brace bolt 82B that cross each other can be connected to each other while adjusting the crossing angle, with one base member 20 being mediated. At this time, the second connecting portion 25 is located at a different position in the longitudinal direction L with respect to the first connecting portion 22 so that the first engaging member 30, the second engaging member 40, and the third engaging member 50 do not interfere with each other. Since the crossing angle of the brace bolt 82B with respect to the reference plane P including the suspension bolt 81 and the brace bolt 82A can be arbitrarily set.

  The first engagement member 30, the second engagement member 40, and the third engagement member 50 are all configured by elastically deformable spring plate members, and with respect to the corresponding bolts 81, 82A, and 82B by elastic restoring force. Since the respective members are engaged and held, the engaging and holding operation between the respective engaging members 30, 40 and 50 and the respective bolts 81, 82A and 82B can be easily performed. That is, each engagement member 30 can be obtained by repeating a series of operations of “elastic deformation of the spring plate member constituting the engagement member → relative proximity movement of the engagement member with respect to the bolt → engagement holding by elastic restoring force” four times. , 40, 50 and the bolts 81, 82A, 82B can be easily engaged and held. Therefore, it is possible to easily connect the suspension bolt 81, the brace bolt 82A that intersects the suspension bolt 81 in the reference plane P, and the brace bolt 82B that intersects the reference plane P.

  Here, in the configuration in which the second connecting portion 25 is provided at a different position in the longitudinal direction L with respect to the first connecting portion 22 as described above, the tensile force from the brace bolt 82B is applied to the third engaging member 50. When acting, a moment of force acts on the base member 20 (specifically, the second connecting portion 25). The second connecting portion 25 is provided away from the first connecting portion 22 along the longitudinal direction L to the extent that the first engaging member 30, the second engaging member 40, and the third engaging member 50 do not interfere with each other. Therefore, the moment of the acting force tends to be particularly large. When such a moment of force acts on the base member 20 (second connecting portion 25), the second connecting portion 25 is on the side opposite to the protruding side 21q (the side on which the protruding piece 23 protrudes) with the first connecting portion 22 as a fulcrum. The base member 20 is bent and deformed in a manner of being displaced to the opposite side. When the base member 20 is bent and deformed, the engagement holding force between at least one set of the engagement members 30, 40, 50 and the corresponding bolts 81, 82 </ b> A, 82 </ b> B is reduced, and in some cases, the base member 20 is detached. there is a possibility.

  Therefore, in the cross connector 1 of the present embodiment, the base member 20 is further provided with the reinforcing portion 26 in addition to the base body portion 21 having the first connecting portion 22 and the extending plate portion 24 having the second connecting portion 25. I have. The reinforcing part 26 is a part that functions to suppress the bending deformation of the base member 20. The reinforcing portion 26 may be one that suppresses deformation of the base member 20 by its inherent characteristics (for example, rigidity, strength, etc.), or the base member by cooperation with other members present in the surroundings. 20 may suppress the bending deformation. The reinforcing portion 26 may be formed integrally with the base main body portion 21 or may be a reinforcing member made of another member that is used while being fixed to the base main body portion 21.

  The reinforcing portion 26 of the present embodiment is formed integrally with the base main body portion 21 and is on the second connecting portion 25 side of the first main connecting portion 22 in the longitudinal direction L of the base main body portion 21 with respect to the suspension bolt 81. The first abutment support portion 27 is engaged from the side opposite to the base main body portion 21. In the present embodiment, the first contact support portion 27 corresponds to a “contact support portion”. More specifically, the first abutting support portion 27 as the reinforcing portion 26 is formed so as to extend from the side of the base body portion 21 and is an L-shaped bent piece integral with the base body portion 21. It consists of The first abutment support portion 27 includes a support plate portion 27A that intersects the base body portion 21 (orthogonal in this example), and a contact plate portion 27B that extends in parallel to the base body portion 21 from the distal end portion of the support plate portion 27A. Including. The support plate portion 27A is arranged so as to extend from the base main body portion 21 in the same direction as the protruding piece 23 (the direction opposite to the extension plate portion 24).

  The extension length of the support plate portion 27A from the base body 21 is set to be equal to or slightly longer than the sum of the distance between the base body 21 and the suspension bolt 81 and the diameter of the suspension bolt 81. ing. For this reason, as shown in FIGS. 5 and 6, the contact plate portion 27 </ b> B is suspended from the back side when viewed from the base body portion 21 with respect to the suspension bolt 81 engaged and held by the first engagement member 30. It contacts the bolt 81. Note that “contact” refers to a mode in which contact can be made quickly when necessary in addition to a mode in which contact is always made (for example, a mode in which contact is made quickly by relative proximity movement when a slight clearance is provided). It is a concept that also includes

  In the present embodiment, the base member 20 includes a plurality of first abutment support portions 27 provided at different positions in the longitudinal direction L of the base main body portion 21 as the reinforcing portion 26. In the present embodiment, a first first abutment support portion 27 is provided at the end of the base main body portion 21 opposite to the first connection portion 22 in the longitudinal direction L, and the first main abutment support portion 27 is provided with respect to the extension plate portion 24. A second first contact support portion 27 is provided at a position in the longitudinal direction L opposite to the first first contact support portion 27.

  By providing the pair of first abutment support portions 27 in this way, a moment of force that can act on the base member 20 (specifically, the second connecting portion 25) when a tensile force from the brace bolt 82B is applied. The suspension bolt 81 can be distributed and received at two different locations in the axial direction. For this reason, even if a relatively large moment of force acts on the base member 20 (second connecting portion 25), the bending deformation of the base member 20 is effectively suppressed or prevented. Therefore, the engagement holding force between the engagement members 30, 40, 50 and the corresponding bolts 81, 82A, 82B can be kept high. For example, even when a large vibration or the like acts, the bolts 81, 82A. , 82B can be effectively suppressed or prevented. Moreover, this effect can be obtained at a low cost by a simple modification of the structure of the base member 20.

  In the present embodiment, the base member 20 is in a state where the first abutment support portion 27 abuts against the suspension bolt 81 in addition to the first abutment support portion 27 as the reinforcing portion 26. Is further provided with a second contact support portion 29 that engages with the suspension bolt 81. The second abutting support portion 29 is formed integrally with the base main body portion 21 at the end of the base main body portion 21 opposite to the first coupling portion 22. The second contact support portion 29 is formed in a rectangular shape. The second contact support portion 29 intersects the base body portion 21 (inclined by about 45 ° in this example) and is disposed so as to extend along the longitudinal direction L of the base body portion 21. Yes. As shown in FIGS. 5 and 6, the second abutment support portion 29 is engaged and held in a notch-shaped recess 34 formed in the inclined plate portion 33 of the first engagement member 30, whereby the base main body portion 21. The suspension bolts 81 that are spaced apart from each other in the thickness direction are supported from the base body 21 side. By further including such a second contact support portion 29, the first contact support portion 27 and the second contact support portion 29 support the suspension bolt 81 from both sides in the direction orthogonal to the base body portion 21. can do. Therefore, the mounting posture of the base member 20 with respect to the suspension bolt 81 can be stabilized.

  As described above, in the present embodiment, the first engagement member 30 is connected to the base member 20 in a state where relative rotation is restricted. For this reason, when the first engagement member 30 is engaged and held with respect to the suspension bolt 81, the base member 20 also moves closer to the suspension bolt 81 side with the rotation operation of the first engagement member 30. To do. Therefore, in the present embodiment, the space S defined by the base main body portion 21 and the first contact support portion 27 is the suspension bolt 81 for the base member 20 when the suspension bolt 81 is engaged with the pair of notch-shaped recesses 34. The direction of the first abutment support portion 27 made of an L-shaped bent piece is set so as to open in a direction to accept the relative proximity movement (see FIGS. 6 and 7). In addition, in FIG. 7, the mode of the relative proximity movement (relative rotation in this example) of the suspension bolt 81 seen from the cross connector 1 side is shown. With this configuration, the suspension bolt 81 is abutted and supported by the operation for causing the suspension bolt 81 to engage and hold the first engagement member 30 and the first abutment support portion 27 additionally provided on the base member 20. Can be performed simultaneously. Therefore, workability can be improved.

  Further, in the present embodiment, as shown in FIG. 6, the corner on the opening side of the first contact support portion 27 in the rectangular second contact support portion 29 is the back side of the first contact support portion 27. It is more rounded than the corner on the support plate portion 27A side. When the surface of the corner portion on the opening side of the second contact support portion 29 welcomes the relative proximity movement of the suspension bolt 81 with respect to the base member 20, the first contact support portion 27, the second contact support portion 29, It functions as a guide surface 29a (an example of guide means) for smoothly introducing the suspension bolt 81 between them. Therefore, the suspension bolt 81 is slidably inserted between the first abutment support portion 27 and the second abutment support portion 29 at the same time as the first engagement member 30 is engaged and held by the suspension bolt 81. Even in this case, the resistance during insertion can be reduced. Therefore, workability can be improved also from this point.

  The cross connector 1 of the present embodiment is also excellent from the viewpoint of preventing erroneous operations during manufacturing (assembly) and construction. For example, at the time of manufacture, the presence of the pair of projecting pieces 23 projecting from the base main body portion 21 exhibits a function of clearly indicating the attachment site of the first engagement member 30 in the first connecting portion 22. In addition, since the extending plate portion 24 is formed in a square or a strip shape close to it, in order to pivotally connect the third engagement member 50 without interfering with the base main body portion 21, the extending plate is used. The third engagement member 50 needs to be attached to the bent outer surface side of the portion 24. For this reason, the three-dimensional shape in which the extension plate part 24 is bent with respect to the base main body part 21 exhibits a function of clearly indicating the attachment site of the third engagement member 50 in the second connection part 25. Furthermore, if the attachment site | part of each of the 1st engagement member 30 and the 3rd engagement member 50 is defined, the attachment site | part of the 2nd engagement member 40 in the 1st connection part 22 will also be decided naturally. Therefore, each engagement member 30, 40, 50 can be easily attached to the appropriate position of the base member 20, respectively.

  Further, for example, at the time of construction, the presence of the pair of protruding pieces 23 protruding from the base main body 21 exhibits a function of clearly indicating the first engaging member 30 to be engaged and held with the suspension bolt 81. For this reason, it is easy to attach the cross connector 1 to the suspension bolt 81 in an appropriate posture.
