[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bush used for inserting and assembling bolts and the like when tightening bolts and the like, wherein the bush is formed by assembling a pair of bush members having the same size and shape. The present invention also relates to the provision of a bush in which legs protruding from a hole edge of a flange-shaped plate in an annular row shape can be engaged and disengaged from each other.

[0002]

2. Description of the Related Art Since a member to be assembled by inserting a bolt or the like is fragile, an edge of a mounting hole of the bolt or the like is easily damaged.
In the case of difficulty in mounting, for example, a bolt or the like used for assembling the window glass of the automobile with the frame of the elevating device, and the edge of the mounting hole of the window glass through which the bolt or the like is inserted are brought into direct contact with each other to form the window glass. Conventionally, a bush is generally used when assembling a bolt or the like so that the hole edge of the mounting hole is not damaged.

The mounting structure of the elevating glass holding portion according to Japanese Utility Model Laid-Open No. 63-112919 is typical of this type of bush. In this mounting structure, the bush is
The first bush is divided into a bush and a second bush, and a first locking projection is formed near the tip of the outer surface of the cylindrical locking portion of the first bush, and near the tip of the inner surface of the cylindrical locking portion of the second bush. After forming the second locking projection and inserting the cylindrical locking portions of both bushes into the mounting holes provided in the window glass, the first bush and the second bush are integrated with the two locking projections,
A bush of this kind has a temporary fixing effect when assembling a mounting hole for a window glass, while forming an insertion cylinder portion such as a bolt.

[0004]

However, this conventional bush has required further improvement mainly in the following three points. First, in this conventional bush, the first
Since the first bush having the locking projection outside the cylindrical locking portion and the second bush having the second locking projection inside the cylindrical locking portion constitute a bush,
The first bush or the second bush cannot form a bush. For this reason, it was necessary to take care not to select bushes that do not engage with each other when assembling the window glass. For example, considerations should be given to placing both bushes in the vicinity of the line by classifying them, consideration for securing space for the vicinity of the line, and furthermore,
Attention has been paid to color-coding both bushes, and a rational solution has been desired. Secondly, even if such considerations are taken, there is an inevitably inconvenience of selecting bushes that cannot be locked. Third, dividing the bush member constituting the bush into two types of parts has necessitated the production of two types of molds for the production of the parts, which has hindered the cost reduction of this type of bush.

Accordingly, the present invention solves the above-mentioned problem of the bush, that is, there is no possibility of selecting bush members that do not engage with each other when assembling the window glass. It is an object of the present invention to provide a bush made of a bush member which does not need to be taken into consideration and can be produced at a low cost, and which can be manufactured at low cost, after being inserted into a mounting hole of a window glass, and locked together in this hole. .

[0006]

In order to achieve the above-mentioned object, according to the present invention, a bush is formed by projecting a flange-like plate having a through hole such as a bolt and the like along a hole edge of the flange-like plate. A pair of bush members having a plurality of leg pieces of the same size and the same shape, wherein the distance between the leg pieces is made equal, and the other bush member has the other between the leg pieces of one bush member. The leg of the bush member is inserted and assembled from the tip side of the leg, and the assembled leg constitutes a cylindrical portion,
In addition, each of the side edges on the width side of the leg piece, which are in contact with each other, has an engaging means consisting of a convex portion and a concave portion, and the engaging means and the leg piece base on the tip end side of the leg piece have And the distance between the engaging means on the base side of the leg and the distal end of the leg is the same.

[0007]

In the bush according to the present invention, a plurality of bush members are provided on a pair of bush members constituting the bush so as to protrude along the hole edge of the flange-shaped plate at equal intervals from the flange-shaped plate. It has leg pieces of the same size and the same shape, and the leg piece of the other bush member is inserted between the leg pieces of one bush member from the tip side of the leg piece so that it can be assembled. Since the engagement means is provided on the width side edges of the pieces that are in contact with each other, the pair of bush members are inserted from both sides of the mounting hole formed in the window glass or the like, and the bush members are engaged with each other. It is assembled in the mounting hole in the temporarily fixed state.
