Abstract

PROBLEM TO BE SOLVED: To easily release the fixed holding of a positioning part in a stud bolt installation position and fixedly hold the part again by connecting a fixing member to a screw part of a stud bolt to be rotatable in the circumferential direction by a holding member fixed to a positioning member to hold the part in a fitting position. SOLUTION: A wire harness is fixed and held to a stud bolt for connecting a head part 23 to the locking part 13 side of a band part 23 to be rotatable in the circumferential direction of a screw part of the stud bolt to fix the head part 23. By the pressure applied at the time of locating a groove-like part 25 in an open space part 33 of a plate-like part 32 and pushing the head part 23 toward an opening part 34 to abut on a slant face of a projection 35, elastic deformation is caused to widen the space between both sides of the open space part 33 so that connection is made unseparably from the opening part 34 by the projection 35. Thus, a hexagon socket of a wrench is fitted in a tool mounting part 26 of the head part 23 rotatably connected to the plate-like part 32, and the screw part is rotated in the separating direction to easily release engagement.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing and holding a positioning component and a method for releasing the holding of the positioning component, and more particularly to a method for easily removing a positioning component fixed and held on stud bolts.

[0002]

2. Description of the Related Art Conventionally, in order to position and fix a component at a designed position, a stud bolt is installed at the mounting position, and a fixing holder fixed to the positioning component is attached to a thread portion of the stud bolt. Generally, the positioning component is held and fixed at the mounting position by engaging and fixing.

As shown in FIG. 7, for example, as shown in FIG. 7, a linear body such as a wire harness for a vehicle is bound by a band portion 2 of a binding band 1 and the binding band 1 is fixed. A fixed holder structure is conceivable in which the head part 3 integrally formed with the stud bolt 7 is engaged with and fixed to the stud bolt 7 shown in FIG.

In this fixed holder structure, as shown in FIG. 8 (a), when a wire harness 9 bound by a binding band 1 is attached to a design position such as a vehicle panel 8 on which a stud bolt 7 is installed. A stud bolt 7 is inserted into the head portion 3 of the binding band 1 to be installed and locked and fixed. At this time, as shown in FIG. 8 (b), while the elastic portion 4a of the elastic deformation portion 4 formed by cutting out the outer peripheral portion of the interior hole is expanded, the head portion 3 has the engaging projection 4b at the tip thereof.
The wire harness 9 can be fixedly held at the mounting position of the vehicle panel 8 by engaging the stud bolt 7 with the thread portion (groove) of the stud bolt 7 and locking the movement in the returning direction so that the wire harness 9 cannot be pulled out. .

[0005]

However, in such a conventional fixed holding, once the stud bolt 7 is used.
When the head portion 3 of the binding band 1 is fixed to the vehicle, the head portion 3 cannot be pulled out from the stud bolt 7. Therefore, to remove the wire harness 9 from the vehicle panel 8, the binding band 1 is removed using a tool or the like. Must be cut off or the head 3 must be broken. For this reason, it is not possible to temporarily test the wiring harness 9 with the wiring harness 9 fixed, and it is also impossible to recycle the wire harness 9 while being bound with the binding band 1. Further, there is a problem that the binding band 1 obtained by cutting the band portion 2 remains on the vehicle panel 8 side, and the work of removing the binding band 1 is heavy.

In the case of a vehicle panel 8 on which a wire harness 9 is routed, there are many places where workability is extremely poor, for example, at the foot of a driver's seat or around an engine room. There is a demand for a simple and reliable structure.

Therefore, the present invention makes it possible to easily fix and hold the positioning component at the position where the stud bolt is installed, and to easily release the fixed holding, so that the fixed holding and recycling can be performed again. An object of the present invention is to provide a fixed holding structure to be realized and a fixed holding release.

And a holding member for holding the fixing member in a mounting position, wherein the holding member connects the fixing member so as to be rotatable in a circumferential direction with respect to a thread portion of the stud bolt.

According to a second aspect of the invention for solving the above-mentioned problems, in addition to the configuration of the first aspect, the fixing member is formed in a tool mounting shape on a side opposite to the interior part in which the stud bolt is installed. And a groove-shaped portion extending in the circumferential direction between the holding member and the tool mounting portion, while the holding member positions the groove-shaped portion of the fixing member in the opening to face the interior portion and the tool mounting portion. And a plate-shaped portion for rotatably holding the fixing member, and the plate-shaped portion is opened to the outside by an open space that extends outward with a width approximately equal to the outer diameter width of the groove-shaped portion. In addition to the above, at the opposing portions defining the open space portion, opposing projections are formed at intervals smaller than the outer diameter width of the groove-shaped portion.

[0010] A third aspect of the present invention for solving the above-mentioned problems is as follows.
In addition to the configuration of the first aspect, the fixing member is formed in a tool mounting shape on a side opposite to the interior portion in which the stud bolt is installed, and extends circumferentially between the interior portion and the tool mounting portion. While having the groove-shaped portion, the holding member has a groove-shaped portion of the fixing member positioned in the opening, and is opposed to both the interior portion and the tool mounting portion so that the holding member is rotatably held by the plate shape. Having a portion, the plate-shaped portion has a structure that can be separated from each other and can be divided, and when separated from each other, the opening portion can be opened outward with an outer diameter width of the groove-shaped portion. It is a feature.

On the other hand, a fourth invention for solving the above-mentioned problem is:
The fixing member is engaged with the stud bolt and fixed to the holding member connected to the fixing member by using the fixing holder adopting the fixing holding structure according to any one of claims 1 to 3. A method of releasing the fixed holding of the positioning component fixedly held at the mounting position where the stud bolt is installed in the state, wherein the holding member is rotated in the circumferential direction with respect to the threaded portion of the stud bolt, thereby holding the stud bolt. Without changing the posture of the stud bolt, the fixing member is guided by the threaded portion of the bolt in the direction of disengaging from the stud bolt to disengage the stud bolt, and together with the fixing member and the holding member, the positioning component is moved to the mounting position. The fixed holding is released.

In the first and fourth aspects of the present invention, the fixing member is connected to the holding member fixed to the positioning component, and without changing the posture of the positioning component and the holding member, without changing the posture of the stud bolt. Can be rotated in the revolving direction with respect to the stud bolt, and can be sent in the pulling-out direction by the screw portion thereof and detached from the stud bolt. Therefore, the positioning component can be easily removed from the mounting position without breaking the fixing member and the holding member.

In the second, third and fourth aspects of the invention, the holding member fixed to the positioning component has the groove-shaped portion between the interior portion of the fixing member and the tool mounting portion in the open space of the plate-shaped portion. Then, by pushing into the opening beyond the projection (first invention), the space between the interior part of the fixing member and the tool mounting part is provided in the opening in which the plate-shaped part is divided and opened to the outside. After the groove-shaped part is positioned, the opening is closed (third invention), so that the plate-shaped part faces the interior part and the tool mounting part, thereby allowing relative rotation. It can be connected to a fixing member fixed to the stud bolt. Further, the fixing member can be rotated with a general tool by the tool mounting portion. Therefore, the connection between the fixing member and the holding member can be performed before or after the fixing member is engaged and fixed to the stud bolt, and the fixing member fixed to the stud bolt can be connected to the holding component fixed to the positioning component. The stud bolt can be rotated in the circumferential direction with respect to the threaded portion without changing the postures of the positioning component and the holding member in the state of being connected to the stud bolt.
