Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a grommet that is used by being spray-painted with a paint such as vinyl chloride sol after being assembled to a member to be attached such as an automobile floor panel.

(Prior art) A grommet is a grommet in which a screw insertion hole is provided in the center and a leg part having an engaging part for preventing the grommet from coming off is hung from the lower surface of the head part (for example, Utility Model Publication No. 54-22839). If a grommet like this is sprayed with a thick coat of paint such as vinyl chloride sol after being assembled to a member to be mounted such as a floor panel, the head will be covered with the paint and the screw insertion hole will also be sprayed. There was a problem in that the grommet was difficult to confirm the position of the grommet when screwing the tatupin screw into the grommet, and the workability was poor.

(Problems that the invention attempts to solve) This invention solves these conventional problems,
This grommet was completed with the aim of making it possible to easily confirm the position of the screw insertion hole in the center even if a thick coating of paint is sprayed onto the member to be attached after attachment.

(Means for solving the problem) The present invention has a body part provided with a locking part on the outer surface, which is vertically provided on the lower surface of the head with a screw insertion hole in the center, and the screws on the upper surface of the head. This is characterized in that an enlarged step is formed at the edge of the insertion hole.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings. First, in the first embodiment shown in FIG.
is a body part with a rectangular cross section that is vertically disposed on the lower surface of the head 1, and the body part 3 has a cylindrical shape with a screw insertion hole 2 in the center, and has an obliquely outward facing surface on the opposite outer surface. A locking portion 4 for preventing slipping off is provided, which includes a pair of locking claw portions 4a. As shown in the figure, there is an enlarged stepped portion 5 at the tip of the screw insertion hole 2 on the top surface of the head 1.
is formed. Further, reference numerals 6 and 6 denote a pair of left and right thin plate-like wing plate parts stretched over the upper edge of the head 1, and when vinyl chloride sol is applied, the wing plate parts 6 protrude from the painted surface. This shows that the grommet is buried between , and 6. Moreover, since these vane plate parts 6, 6 are thin plate-like parts that are easily flexible, there will be no inconvenience when attaching other members.

Next, the second and third embodiments shown in FIGS. 2 and 3 are different from the first embodiment in the body portion 3 and the locking portion 4, but are otherwise the same. I will only explain. In the second embodiment shown in FIG. 2, the body 3 is formed by inwardly bendable body pieces 3a, 3a, which are divided into two by a slit 7 provided upward from the lower end. Further, the locking portion 4 is formed by forming the outer surface of each body piece portion 3a into a tapered surface 4b having a bulging shape. In the third embodiment shown in FIG. 3, the body 3 is made of a square cylinder with a bottom, and the locking part 4 is made of a protrusion 4c projecting from the wall surface 3c of the cylinder 3b. has been done.

(Function) As shown in FIG. 1, the body 3 is fitted into a substantially rectangular fitting hole 12 previously provided in a member 11 to be mounted, such as a floor panel, and The locking part 4 provided on the outer surface of the body part 3 prevents it from coming off even when the body part 11 is reversed, and it is spray-painted with a paint such as vinyl chloride sol for rust prevention.
Thereafter, by inserting a tatsu pin screw into the screw insertion hole 2 transparently provided in the center of the head 1 and pushing the body 3 apart, it is strongly engaged with the member 11 to be attached, and the member for attaching small parts, etc. It is the same as a conventional grommet in that it is screwed on. However, since the grommet according to the present invention has an enlarged stepped portion 5 formed at the edge of the screw insertion hole 2 on the top surface of the head 1, a paint such as vinyl chloride sol is spray-painted to prevent rust. Since the enlarged stepped portion 5 is not completely closed even if the grommet is painted, the position of the grommet can be easily confirmed after painting. Further, the enlarged step portion 5 to which the paint 13 is attached and the screw insertion hole 2 are smoothly connected by the paint 13, and the enlarged step portion 5 functions as an enlarged diameter portion for groping with respect to the screw insertion hole 2. It also has the advantage of making it easy to insert screws with pins. Moreover, since the pair of left and right wing plates 6, 6 which are easily flexible are stretched over the upper edge of the head 1, when the vinyl chloride sol is applied, the wing plate parts 6 protrude from the painted surface. By clearly indicating that the grommet is buried between 6 and 6, it is no longer necessary to search for the grommet position when inserting the tut pin screw, and the efficiency of the work of inserting the tut pin screw can be further improved. can. Moreover, since the flexible wing plate portions 6, 6 are easily bent, they do not interfere with other operations.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
Since a pair of flexible wing plates are attached to the upper edge of the head, even if the head is buried in the coating when vinyl chloride sol is applied, the wing plates protrude from the painted surface and a grommet is formed between the two wing plates. In addition to clearly indicating that the screw is buried, the enlarged step formed at the edge of the screw insertion hole prevents the screw insertion hole from being blocked, making it easier to locate the screw insertion hole. Confirmation can be made easily, and since this enlarged stepped portion also acts as an enlarged diameter portion for searching, the efficiency of the screw insertion work of the tutpin screw can be improved. In addition, since both wing plate parts are easily bent, they do not interfere with other work.

Therefore, the present invention has great practical value as it solves the problems of conventional grommets.
