Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fastener used when a plurality of objects are fastened and fixed using mounting screws.

For example, as shown in FIG. 1, when fixing the mounted body 2 to the mounting body 1 using mounting screws 3,
Positional accuracy of the mounting position on the object 2 to be mounted may be required. In such a case, if the dimensional accuracy of the mounting body 1 and the mounted body 2 is high, there will be no problem, but if the dimensional accuracy is poor and a gap is created between the mounting body 1 and the mounted body 2. In this method, a spacer 4 is interposed between the mounting body 1 and the mounted body 2 to regulate the mounting position. Note that 5 is a washsha.

However, if the thickness dimension of the spacer 4 is determined in advance, it is not possible to absorb various dimensional errors that occur between the mounting body 1 and the mounted body 2. There is an inconvenience that spacers of various sizes must be prepared in advance. In addition, if you cannot reach the back sides of both attached objects 2,
Since it is extremely difficult to insert and hold the spacer 4 in the gap between the two, the workability is poor, and sometimes it is impossible to insert the spacer.

The present invention was devised to eliminate such inconveniences, and its purpose is to provide a fastener with infinite dimensions that can deal with gaps of various dimensions that occur between the mounting body and the mounted body, which are not in a parallel positional relationship. Moreover, such a fastener can be easily positioned between the mounting body and the mounted body.

The present invention will be explained in detail below based on an embodiment shown in FIGS. 2 to 5.

1 is the mounting body, 2 is the mounted body, and both are the second
As shown in the figure, they are assembled in a non-parallel positional relationship. Reference numeral 6 denotes a fastener to be fixed in position within the gap created between the attaching body 1 and the attached body 2, and this fastener 6 includes an outer member 7, an intermediate member 8, and It consists of an inner member 9. This outer member 7 includes a collar portion 7 ₁ provided at one end and a locking claw portion 7 ₂ provided at the other end.
The intermediate member 8 has a female screw portion 8 on the inner peripheral surface.
A pair of support parts ₈₂ are provided protruding from the outside of the cylindrical body forming the intermediate member 8, and the intermediate member 8 is rotatably pivotally connected to the outer member ₇ via the support parts ₈₂ . It is something that The inner member 9 has a male screw portion ₉₁ formed on the outer circumference and screwed into the female screw portion ₈₁ , an abutment portion ₉₂ formed on one end, and a mounting screw 3 formed on the inner circumference. It has an insertion hole ₉₃ . Note that 1' is a screw portion formed in advance on the mounting body 1, and 2' is a through hole formed on the mounting body 2.

Next, the function of the fastener 6 will be described with reference to FIGS. 4 and 5. 4 and 5 are cross-sectional views of the fastener 6 shown in the second figure, cut along a plane passing through the center of the fastener and parallel to the plane of the drawing. First, the outer member 7 of the fastener 6, which is formed by screwing the inner member 9 onto the female screw portion ₈₁ of the intermediate member 8 which is pivotally attached to the outer member 7, is inserted into the through hole 2' of the object to be attached 2, and the outer member 7 is Tsuba 7 of member 7
₁ and the locking claw portion ₇₂ , it is clamped and fixed within the through hole 2' of the object to be attached 2 (see FIG. 4). Next, the intermediate member 8 is fixed so that its central axis C is connected to the threaded portion 1' of the mounting body 1.
outer member 7 around axis B so as to coincide with the axis of
The insertion hole 9 of the inner member 9
When the mounting screw ₃ is frictionally inserted into the inner member 3 and rotated, the frictional coupling force between the mounting screw 3 and the inner member 9 is greater than the threaded coupling force between the intermediate member 8 and the inner member 9. Since the inner member 9 is also large, the inner member 9 rotates relative to the intermediate member 8 as the mounting screw 3 rotates, and the inner member 9 is fed out, so that the contact portion ₉₂ of the inner member 9 contacts the mounting body. 1, the inner member 9 is no longer rotated (see FIG. 5). Then, when the mounting screw 3 is further rotated, this mounting screw 3 screws into the threaded part 1' formed on the mounting body 1, and when the mounting screw 3 is completely screwed in, the mounting body 1 and the mounted body 2 are separated. Fastener 6 and mounting screw 3
It is fixed integrally through the. Therefore, according to this fastener 6, since the inner member 9 is extended according to the gap created between the attaching body 1 and the attached body 2, a fastener that can be adjusted steplessly according to the gap is provided. It is possible. Furthermore, since the fastener according to this embodiment can be engaged and held in advance with the object to be attached, there is no need to take pains to keep the fastener in place within the gap, as is the case with conventional spacers, and there are advantages such as providing a fastener with good workability. .

As described above, in the present invention, the outer member 7 is fixed near the edge of the through hole 2' drilled in the attached body 2.
and a cylindrical intermediate member 8 which is pivotally attached to the outer member 7 via a pivot member ₈₂ so as to be swingable within the through hole 2' and has a female threaded portion ₈₁ formed on its inner circumferential surface. , a male threaded portion 91 is formed on the outer circumferential surface of the intermediate member 8, which is movably screwed into the female threaded portion ₈₁ on the inner circumferential surface of the intermediate member ₈ until the contact portion ₉₂ abuts the surface of the mounting body 1; and a cylindrical inner member having an inner circumferential surface with an inner diameter that can be engaged with the mounting screw 3 screwed into the threaded portion 1' of the mounting body 1 with a stronger coupling force than the threaded coupling force with the intermediate member 8. According to this fastener, even when the object to be attached 2 has to be attached in an inclined positional relationship with respect to the attaching body 1, this fastener can be used to attach it at multiple points. If the mounted body 2 is fixed to the mounting body 1, the mounted body 2 can be fixed to the mounting body 1 without play, which has the effect of improving the design constraints of the mounting body and the mounted body. .

Furthermore, according to this fastener, the dimensions can be increased or decreased steplessly by following the width of the gap created between the mounting body and the mounted object, and the dimension can be adjusted steplessly when the mounting screw is screwed in. Since this is done automatically, there is an effect that the workability of joining the object to be attached to the attachment body is excellent.
