  In the conventional fixture, since it is substantially difficult to engage the four first locking claws and the two auxiliary locking claws with the locking projections of the rod-shaped member with the same engagement force, The first locking claw at the outer side edge of the joint recess is set as the main engaging claw, and the inner side edge of the both engaging recesses is set as an auxiliary locking claw for receiving the reaction force. .

  For this reason, in the locking structure mainly composed of the first locking claws of both engaging recesses, the mounting member and the rod-shaped member are connected with the first locking claws engaged with the locking projections of the rod-shaped member. On the other hand, when a large external force acts in the direction of the rod axis and the mounting member and the rod-like member move relative to each other along the direction of the axis of the rod due to this external force, the first force on the external force receiving side that becomes one of the relative movement directions. There is a possibility that the load concentrates on the engaging portion between the one locking claw and the locking projection of the rod-shaped member, and the engagement between the first locking claw and the locking projection of the rod-shaped member is disengaged.

  When such a disengagement phenomenon of the first locking claws occurs, the mounting position of the mounting member varies with respect to the setting mounting position of the rod-shaped member, so that the steadying of the suspended equipment in which the mounting tool is used as a component part There is an inconvenience which has a bad influence in the cross-connecting tool and the long body attachment tool.

  The present invention has been made in view of the above-described actual situation, and its main problem is that the load resistance is increased by rational modification of the engagement structure of the mounting member with respect to the rod-shaped member, and due to the external force in the rod axis direction. It is in the point which provides the fixture which can suppress the position shift movement of an attachment member.

A first characteristic configuration according to the present invention is an elastically deformable mounting member including a mounting plate portion to which another object can be mounted and an inclined plate portion extending in an inclined posture in a direction away from each other from both ends of the mounting plate portion. Among these, the both inclined plate portions can be engaged from the crossing direction with respect to the rod-shaped member having a number of locking projections by the elastic deformation operation of the mounting member toward the side where the both inclined plate portions are brought close to each other. An engagement recess is formed, and the first engagement pawl is formed in both engagement recesses and is engaged and held by the engagement protrusion of the rod-shaped member by the elastic restoring force of the attachment member. And
At least one of the attachment member and the rod-shaped member relative to each other in the rod axis direction in a state where the first locking claws of the both engaging recesses are engaged with the locking projections of the rod-shaped member. There is provided an engagement pressing means for pressing in the direction of increasing the engagement force between the first locking claw and the locking projection of the rod-shaped member.

According to the above configuration, in the state where the first locking claws of the both engaging recesses are engaged with the locking projections of the rod-shaped member, the external force in the rod axis direction acts on the mounting member and the rod-shaped member. Thus, when the attachment member and the rod-shaped member move relative to each other along the axial direction of the rod by this external force, the engagement pressing means strengthens the engagement force between at least one of the first locking claws and the locking projection of the rod-shaped member. Since it can be pressed in the direction, the load resistance by the first locking claws can be increased.
Thereby, it is possible to suppress the loss of the locking protrusions of the rod-shaped member due to the disengagement displacement of the first locking claws in the state where the external force in the rod axis direction acts as a large concentrated load.

  Therefore, the load resistance can be increased by a rational modification of providing an engagement pressing means utilizing the relative movement of the mounting member and the rod-shaped member in the direction of the rod axis, and the mounting member can be increased by an external force in the direction of the rod axis. The displacement movement can be suppressed.

  According to a second characteristic configuration of the present invention, the engagement pressing means includes a second locking claw that can be engaged with the locking projection of the rod-shaped member from the side opposite to the first locking claws. When the second locking claw is engaged with the locking projection of the rod-shaped member, the mounting member and the rod-shaped member are displaced to protrude toward the rod axis as the relative movement in the rod axis direction occurs. It is in the point comprised from the press board part.

  According to the above configuration, the mounting member and the rod-shaped member in the state where the first locking claws of the both engaging recesses and the second locking claw of the pressing plate portion are engaged with the corresponding locking protrusions of the rod-shaped member. When an external force in the direction of the rod axis acts on the member, and the attachment member and the rod-like member move relative to each other along the axis of the rod axis due to this external force, the rod-like shape is formed from the opposite side to the first locking claws. The pressing plate portion provided with the second locking claw engaged with the locking protrusion of the member is projected and displaced toward the rod axis side with the relative movement of the mounting member and the rod-shaped member in the rod axis direction. Therefore, at least one of the first locking claws can be pulled toward the rod axis side of the rod-like member to increase the engagement force between the first locking claw and the locking projection, and accordingly, the second locking claw The engaging force between the claw and the locking projection can also be increased.

  Therefore, the external force in the direction of the rod axis acting on the mounting member and the rod-shaped member can be received by being distributed to the first locking claw and the second locking claw, and the first locking claw and the second locking claw. Since each engaging force of the pawl can be strengthened at the same time, the external force in the direction of the rod axis acting on the first and second engaging claws of the mounting member and the engaging projection of the rod-like member can be reliably and strongly received. Can do.

  According to a third characteristic configuration of the present invention, the first locking claw is formed on an end edge of the engaging recess on the outer side in the rod axis direction, and the pressing plate portion is formed on the mounting member. Provided at two locations on the mounting plate portion side with respect to both first locking claws, and one pressing plate portion is accompanied by movement of the mounting member relative to the rod-shaped member in one direction along the axial direction of the rod. And the other pressing plate is configured to project and displace to the rod axis side as the mounting member relative to the rod member moves in the other direction along the rod axis direction. It is in a certain point.

  According to the said structure, the 1st latching claw formed in the outer side edge of both engagement recessed parts and the 2nd latching claw of both the press board parts engage with the latching protrusion of the rod-shaped member corresponding to them When an external force in the direction of the rod axis acts on the mounting member and the rod-shaped member in a state where the mounting member and the rod-shaped member move relative to each other along the axis of the rod axis due to the external force, the rod-shaped member For the movement of the mounting member in one direction along the axial direction of the rod axis, the pressing plate portions provided at two portions of the mounting member that are biased toward the mounting plate portion side with respect to both first locking claws One of the first locking claws is projected and displaced from the side opposite to the first locking claw to the bar shaft core side, and at least one first locking claw is drawn toward the bar shaft core side of the bar-shaped member to thereby form the first locking claw and the bar shape. The engaging force with the locking protrusion of the member is strengthened.

  For the movement of the attachment member relative to the rod-shaped member in the other direction along the axis direction of the rod, the other pressing plate portion projects and displaces from the side opposite to the first locking claw to the axis side of the rod, At least one of the first locking claws is drawn toward the rod axis side of the rod-shaped member to increase the engagement force between the first locking claws and the locking projections of the rod-shaped member.

  Therefore, the rod shaft core that acts on the first and second locking claws of the mounting member and the locking projection of the rod-shaped member regardless of the relative movement direction of the mounting member and the rod-shaped member due to external force. The external force in the direction can be received reliably and strongly.

  According to a fourth characteristic configuration of the present invention, the first locking claw is formed at an edge on the inner side in the rod axis direction of the engagement recess, and the pressing plate portion is formed on the mounting member. It is provided at two locations of the portion biased outward in the rod axis direction from both first locking claws, and one pressing plate portion is in one direction along the rod axis direction of the mounting member with respect to the rod-shaped member. Along with the movement, it projects and displaces toward the bar axis, and the other pressing plate part projects and displaces toward the bar axis along with the movement of the mounting member relative to the bar-shaped member in the other direction along the direction of the bar axis. It is in the point which is made the structure to do.

  According to the above configuration, the first locking claws formed at the inner side edges of the both engaging recesses and the second locking claws of the both pressing plate portions correspond to them, but are engaged with the locking protrusions of the rod-shaped member. When an external force in the direction of the rod axis acts on the mounting member and the rod-shaped member in a combined state, and the mounting member and the rod-shaped member relatively move along the axis of the rod axis due to this external force, For movement of the mounting member in one direction along the rod axis direction relative to the member, the mounting member is provided at two locations on the mounting member that are biased outward in the rod axis direction relative to both first locking claws. One of the pressed plate portions projects and displaces from the side opposite to the first locking claw to the rod axis side, and pulls at least one first locking claw toward the rod axis side of the rod-shaped member to thereby cause the first engagement. The engaging force between the pawl and the locking projection of the rod-shaped member is strengthened.

  For the movement of the attachment member relative to the rod-shaped member in the other direction along the axis direction of the rod, the other pressing plate portion projects and displaces from the side opposite to the first locking claw to the axis side of the rod, At least one of the first locking claws is pulled toward the rod axis side of the rod-shaped member to increase the engagement force between the first locking claw and the locking projection.

  Therefore, the rod shaft core that acts on the first and second locking claws of the mounting member and the locking projection of the rod-shaped member regardless of the relative movement direction of the mounting member and the rod-shaped member due to external force. The external force in the direction can be received reliably and strongly.

  According to a fifth characteristic configuration of the present invention, the both pressing plate portions are in an inclined posture facing the central position side of the mounting member in the axis direction of the mounting member or in an inclined posture facing both ends of the mounting member in the axis direction of the rod axis. It is in the point formed by bending from.

  According to the said structure, compared with the case where both the press board parts are comprised separately from the attachment member, reduction of a manufacturing process and simplification of a structure can be aimed at.

  According to a sixth feature of the present invention, a retaining piece for preventing contact of the rod-shaped member that is engaged with the first locking claw protrudes from the opening side of the engaging recess of the mounting member. The protruding margin of the retaining piece is formed to have a dimension substantially corresponding to the radius of the rod-shaped member or a dimension larger than that.

  According to the above configuration, the mounting member and the rod-shaped member are engaged with the engaging recesses of the mounting member and the first locking claw is engaged with the locking projection of the rod-shaped member. Even if an external force acts in the disengagement direction, the disengagement movement is reliably prevented by the contact between the retaining piece and the rod-shaped member that has a projecting dimension substantially corresponding to the radius of the rod-shaped member or a larger projecting dimension. be able to.

  According to a seventh characteristic configuration of the present invention, the engagement recess of the mounting member has an engagement state with the first locking claw on the opening side of the edge facing the first locking claw in the rod axis direction. The retaining piece for preventing the rod-like member from moving out of contact is projected and formed.

According to the above configuration, the mounting member and the rod-shaped member are engaged with the engaging recesses of the mounting member and the first locking claw is engaged with the locking projection of the rod-shaped member. When an external force in the direction of separation acts on the pin, even if the retaining piece is twisted by this external force, a first locking claw is formed on the side facing the end edge where the retaining piece is formed in the direction of the rod axis. Therefore, it can suppress that this 1st formation nail receives the influence of the deformation | transformation by twist of a retaining piece.
Therefore, it is possible to suppress a decrease in the engaging force of the first locking claws due to the twist of the retaining piece due to the external force in the separation direction.

  According to an eighth characteristic configuration of the present invention, the retaining piece is formed by being cut and raised at an end portion on the inner side in the rod axis direction of the engaging recess of the mounting member. In the vicinity, the reinforcing convex portion is bulged.

  According to the above configuration, the number of manufacturing steps can be reduced and the structure can be simplified as compared with the case where the retaining piece is configured separately from the mounting member, and such a cutting and raising method is adopted. However, the strength of the retaining piece can be sufficiently ensured by the reinforcing convex portion bulging and formed near the base of the retaining piece.

  According to a ninth feature of the present invention, the other object is one or a plurality of other mounting members that can be engaged and connected to another bar-shaped member, and the other one or a plurality of mounting members are the mounting members. It is in the point that it is pivotally connected so as to be relatively rotatable in a state of being superimposed on the mounting plate portion of the member.

  According to the above configuration, when two or more rod-shaped bodies are coupled in an intersecting posture, a plurality of attachment members having the same number of engaging portions as the maximum set coupling number in the stacked state are attached to the rod-shaped bodies to be engaged. When the engagement operation is completed by rotating the corresponding orientation posture to engage the engagement recess formed in each mounting member with the rod-shaped body to be engaged, The engagement can be maintained by utilizing the elastic restoring force of the operated mounting member.

  Therefore, since only one or a plurality of other mounting members are superposed on the mounting plate portion of the mounting member and pivotally connected so as to be relatively rotatable, while achieving weight reduction and downsizing and manufacturing cost reduction, Two or more rod-shaped bodies can be quickly and easily connected in a crossing posture, and on the mounting member side of the present invention, the external force acting on the rod axis direction acting on the mounting member and the rod-shaped member is applied to the locking projection. It can be reliably received without any defects.

[First Embodiment]
FIGS. 1-4 shows the fixture A equipped with the state which can be attached or detached with respect to the volt | bolts 1 which are an example of a rod-shaped member, such as a suspension bolt and a steady-state bolt.

  The attachment A includes an attachment plate portion 2A to which the other object B can be attached, an inclined plate portion 2B extending in an inclined posture away from each other on the same side, and both the inclined plate portions 2B. An attachment member 2 made of an elastically deformable sheet metal provided with an operation plate portion 2C that can be sandwiched and operated by a finger extending to the distal end side is provided as a main component.

  The two inclined plate portions 2B of the mounting member 2 can be engaged and disengaged with respect to the bolt 1 from the crossing direction by an elastic deformation operation by the two operation plate portions 2C toward the side where the two inclined plate portions 2B are brought closer to each other. The engaging recess 3 to be engaged is cut out in a state of opening in opposite directions on different sides of the both inclined plate portions 2B.

  Of the end edge 2a on the outer side of the bolt shaft core X direction (bar shaft core direction) in both engaging recesses 3 of the mounting member 2, an edge portion corresponding to the set engagement position of the bolt 1 is provided. A first locking claw 4 is formed that is engaged and held by a threaded portion (a thread or thread groove in one example of a plurality of locking protrusions of the rod-shaped member) 1a of the bolt 1 by elastic restoring force. One locking claw 4 is configured in an inclined posture along the spiral direction of the threaded portion 1 a of the bolt 1.

  Out of the end edges 2b on the inner side of the bolt core X direction (rod axis direction) in both engaging recesses 3 of the mounting member 2, the edge portions corresponding to the set engagement position of the bolt 1 are a pair of later-described pairs. The second locking claws 5a and 5b of the pressing plate portions 5A and 5B are configured in a non-contact state with the bolt 1.

  Bolt shaft core of the mounting member 2 and the bolt 1 in a state where the first locking claws 4 of the both engaging recesses 3 of the mounting member 2 are engaged with the threaded portion (thread or thread groove) 1a of the bolt 1 With relative movement in the X direction, an engagement pressing means 5 is provided for pressing in the direction in which the engagement force between at least one of the first locking claws 4 and the screw portion 1a of the bolt 1 is increased.

  The engagement pressing means 5 includes second locking claws 5a and 5b that can be engaged with the screw portion 1a of the bolt 1 from the opposite side of the first locking claws 4, and the second locking claws. A pair of protrusions and displacements toward the bolt shaft X side with relative movement of the mounting member 2 and the bolt 1 in the bolt shaft core X direction in a state where the screws 5a and 5b are engaged with the screw portion 1a of the bolt 1. It consists of pressing plate portions 5A and 5B.

  Each of the second locking claws 5a, 5b of the pressing plate portions 5A, 5B is inclined in a direction opposite to the direction in which the external force is applied in the direction of the bolt axis X, and cooperates with both the first locking claws 4. The second locking claws 5a and 5b are each configured in an inclined posture along the spiral direction of the screw portion 1a of the bolt 1.

  Further, the pressing plate portions 5A and 5B are located at two portions of the mounting member 2 that are biased to the mounting plate portion 2A side with respect to both the first locking claws 4; that is, with the two inclined plate portions 2B in the mounting plate portion 2A. At two locations that are biased toward the boundary side, the mounting member 2 is cut and raised in an inclined posture toward the central position in the rod axis direction.

  The protruding height from the line segment connecting the second locking claws 5a, 5b of the both pressing plate portions 5A, 5B to the surface of the mounting plate portion 2A causes the inner side edge 2b of the both engaging recesses 3 of the mounting member 2 to move. It is configured to be larger than the height from the connecting line segment to the surface of the mounting plate portion 2A.

  One pressing plate portion 5A starts from a bent base end portion on the bolt shaft X side as the mounting member 2 moves in one direction (direction of arrow a in FIG. 4) of the bolt 1 with respect to the mounting member 2. The other pressing plate portion 5B is displaced while standing up and down, and the other pressing plate portion 5B is moved along the bolt axis X direction of the bolt 1 with respect to the mounting member 2 in the other direction (direction of arrow b in FIG. 4). Thus, it is configured to project and displace while swinging up and starting from the bent base end on the bolt shaft X side.

And the 1st latching claw 4 formed in the outer side edge 2a of both the engagement recessed parts 3 in the attachment member 2 and the 2nd latching claw 5a, 5b of both the press board parts 5A and 5B respond | correspond to them. An external force in the direction of the bolt axis X acts on the mounting member 2 and the bolt 1 in a state in which the bolt 1 is engaged with a threaded portion (thread or groove) 1a. When the bolt 1 and the bolt 1 move relative to each other along the bolt axis X direction, the bolt 1 moves relative to the mounting member 2 in one direction along the bolt axis X direction (the direction of arrow a in FIG. 4). One pressing plate portion 5 </ b> A facing the direction of movement projects and displaces from the side opposite to the first locking claw 4 to the bolt axis X side.
With this projecting displacement, the bolt holding width between the tip of the second locking claw 5a and the tip of the first locking claw 4 of one pressing plate portion 5A becomes narrower, and both the first locking claws 4 are connected to the bolt 1. It will be drawn to the bolt axis X side and will bite into the screw part 1a of the bolt 1 strongly.

  In addition, since the second locking claw 5a of the one pressing plate portion 5A also bites into the screw portion 1a of the bolt 1, the first locking claw 4 and the second locking claw 5a of the one pressing plate portion 5A The bolt 1 will be held strongly.

For the movement of the bolt 1 with respect to the mounting member 2 in the other direction along the direction of the bolt axis X (the direction of the arrow b in FIG. 4), the other pressing plate portion 5B facing the direction of the movement is It projects and displaces from the opposite side to the one locking claw 4 to the bolt axis X side.
With this projecting displacement, the bolt holding width between the tip of the second locking claw 5b and the tip of the first locking claw 4 of the other pressing plate portion 5B becomes narrow, and both the first locking claws 4 are connected to the bolt 1. It will be drawn to the bolt axis X side and will bite into the screw part 1a of the bolt 1 strongly.
Moreover, since the second locking claw 5b of the other pressing plate portion 5B also bites into the screw portion 1a of the bolt 1, both the first locking claws 4 and the second locking claw 5b of the other pressing plate portion 5B are used. The bolt 1 will be held strongly.

  Accordingly, the external force in the direction of the bolt axis X acting on the mounting member 2 and the bolt 1 can be distributed and received by both the first locking claws 4 and the second locking claws 5a and 5b. Since each engaging force of the 1 locking claw 4 and the 2nd locking claw 5a, 5b can also be strengthened, both the 1st locking claw 4 and 2nd locking claw 5a, 5b of the attachment member 2, and the screw | thread of bolt 1 The external force in the direction of the bolt shaft core X acting on the portion 1a can be reliably and strongly received.

  In addition, the bolt 1 that is engaged with both the first locking claws 4 and the second locking claws 5a and 5b is provided at the opening side portion of the inner side edge 2b of the both engagement recesses 3 of the mounting member 2. A retaining piece 6 that abuts on the radially outer side and prevents the bolt 1 from coming out is prevented from protruding by being cut and raised in substantially the same direction as the inclination of the pressing plate portions 5A and 5B. The protrusion margin of the piece 6 is configured to have a dimension substantially corresponding to the radius of the bolt 1.

  The contour shape of the retaining piece 6 is a stopper surface 6a that intersects the inclined plate portion 2B of the mounting member 2 at a right angle or a steep inclination, and one side of the mounting plate portion 2A in the width direction from the top of the stopper surface 6a. And the engagement / disengagement guide surface 6b of the bolt 1 which is curved or inclined toward the center.

  Then, in a state where the bolt 1 is engaged with both the engaging recesses 3 of the mounting member 2 and the first locking claw 4 is engaged with the screw portion 1a of the bolt 1, the mounting member 2 and the bolt 1 When an external force in the direction of separation (lateral displacement force orthogonal to the direction of the bolt axis X) acts on the inner side where the retaining piece 6 is formed even if the retaining piece 6 is twisted by this external force Since the first locking claw 4 is formed on the outer side edge 2a facing the end edge 2b in the bolt axis X direction, the first forming claw 4 has an effect of deformation caused by twisting of the retaining piece 6. It can suppress receiving, and the fall of the engaging force of the 1st latching claw 4 resulting from the twist of this retaining piece 6 can be suppressed favorably.

Further, the retaining piece 6 is configured to be in contact with the bolt 1 in a state where the bolt 1 is engaged with both the engaging recesses 3 of the mounting member 2, and the first locking claw 4 is configured to be engaged with the engaging recess 3. It is comprised in the inclination attitude | position which adjoins the inner side edge 2b which opposes in the volt | bolt axis X direction toward the opening side.
Therefore, the retaining piece 6 also shares the function of receiving the displacement in the bolt axis X direction, and the first locking claw 4 also shares the function of receiving the external force in the disengaging direction.

  Further, of the two inclined plate portions 2B of the mounting member 2, the inner side edge 2c on the inner side facing the opening (engagement / disengagement port) of both engagement recesses 3 in the radial direction of the bolt 1 and the opening side of both engagement recesses 3 Along the center part between the opposite side to the side part and the side part of the side of the formation area of the pressing plate parts 5A, 5B in the mounting plate part 2A continuous to the central part, along the direction of the bolt axis X Thus, the first reinforcing convex portion 7 having a semi-circular or semi-elliptical transverse cross-sectional shape is formed to bulge.

  Further, a portion located on one diagonal line of the mounting plate portion 2A of the mounting member 2 and in the vicinity of the cut-and-raised base portion of the retaining piece 6 and the cut-and-raised base portions of the pressing plate portions 5A and 5B is linear. A second reinforcing projection 8 having a semicircular or semi-oval cross-sectional shape is formed to bulge.

  Further, a circular mounting hole 9 for the other object B and a connecting seat surface portion 10 that slightly bulges to the back surface side at the outer peripheral portion thereof are formed in the central portion of the mounting plate portion 2A of the mounting member 2.

  Next, as shown in FIG. 5, for example, the fixture A of the present invention formed as described above is suspended from a base material D such as an air conditioner, a cable rack, and a duct on a structure S such as a ceiling slab. A case will be described in which a suspension bolt 1A (an example of a bar-shaped member) to be installed and a steadying bolt 1B (an example of a bar-shaped member) disposed in a crossing posture are used as components of a cross connector.
