Problems solved by technology

[0005] However, in the conventional connecting member, when the connecting and fixing process of the two plate members is completed, the top end of the shaft portion of the pin largely protrudes outward from the top edge of the separated leg piece.
Therefore, when another process is performed at the rear side of the protruding end, if the worker mistakenly pushes the top end of the shaft portion of the protruding pin or when installing another part said another part abuts against the protruding If the top end of the shaft portion of the pin is removed, the connecting member may be disengaged from the mounting hole of the plate member or the pin may be returned to the temporarily engaged state although the connecting member is not disengaged.
Therefore, the connecting and fixing process of the plate elements needs to be performed again, or the plate elements may be conveyed to the next process without noticing that the connecting and fixing state of the plate elements has been released

Embodiment Construction

[0031] Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 , the connecting element in this embodiment is also composed of a grommet 1 and a pin 2 like the conventional connecting element. Both the grommet and the pin are integrally made of synthetic resin. The grommet 1 has a flange portion 3 in the shape of a large disc and a leg portion 4 in the shape of a cylinder. The pin 2 has a small disc-shaped head part 5 and a cylindrical shaft part 6 .

[0032]As shown in FIGS. 2A and 2B , in the grommet 1 , an insertion hole 7 for inserting the shaft portion 6 of the pin 2 therein is formed from the center of the flange portion 3 to the inside of the foot portion 4 . The foot part 4 is divided into pieces by four slits 8 so that the pieces can be opened outwards. At the inner surface of the expanded top end side of each divided leg piece 4a is formed an engaging nail 9 that engages with an engaging surface ...

Abstract

A jointing member has a grommet and a pin. The grommet includes a flange portion and a leg portion capable of being opened, in which an insertion hole is formed from the center of the flange portion to the inner portion of the leg portion, and an engagement nail is formed at the inner surface of the leg portion. The pin includes a head portion and a shaft portion to be inserted into the insertion hole, in which an engagement surface and a lock surface each engaging with the engagement nails are formed at the shaft portion. In the jointed and fixed state of panel members, when an unexpected external force is applied to the tip end of the shaft portion of the pin, the engagement nail engages with the lock surface of the pin.

Description

technical field [0001] The present invention relates to a connection element consisting of a grommet and a pin, wherein two plate elements can be connected from at least one direction by a one-touch operation to fix the two plate elements. Background technique [0002] Although not specifically shown, the connecting elements are conventionally formed of grommets and pins. Each of the grommet and the pin is integrally made of synthetic resin. The grommet has a flange portion and a foot portion, wherein an insertion hole for inserting a shaft portion of a pin described later is formed from the center of the flange portion to the inside of the foot portion. The leg portion is divided into a plurality of pieces by slits so that the pieces can be opened outward, and at the inner surface of each divided leg piece is formed an engagement with a large-diameter groove of a pin described later. nail. The pin has a head portion and a shaft portion, wherein a large-diameter groove fo...
