BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fixture used for fixing various plate materials such as automobile garnish to a mounting base such as a body panel.

[0002]

2. Description of the Related Art As a conventional fixing device of this type, there is, for example, one disclosed in Japanese Utility Model Laid-Open No. 61-166216. Although not specifically shown, the conventional fixture uses a long bolt that is planted in a mounting base such as a body panel to fix a plate member having a through hole formed in the mounting base. It was developed on the premise that the specific structure consists of an enlarged head and a tubular body integrally molded with synthetic resin,
A pair of elastic locking claws that engage with the threaded surface of the long bolt are formed on the opposite side walls of the tubular body. Then, in actual use, after inserting the tip of the long bolt planted on the mounting base side into the through hole that is pre-drilled on the plate side and stacking the plate on the mounting base, By inserting the tubular body of the fixing tool into the through hole of the fixture and exposing the tip of the long bolt to the inside of the tubular body, the elastic surface of the tubular body is attached to the threaded surface of the bolt. Since the locking claws are elastically locked to hold the plate member between the enlarged head of the fixture and the holding state, the plate member is fixed to the mounting base. Therefore, in the conventional fixture, the plate member can be easily fixed to the mounting base simply by forming the whole into a cap shape that can be locked to the tip of the long bolt.

[0003]

However, in such a conventional fixture, since the fixing force of the plate member is to be obtained by the engagement of the pair of elastic locking claws with the screw surface of the bolt, When the fixing state is weakened by itself, the plate material may be inadvertently rattled, and when it becomes necessary to release the fixing of the plate material, forcibly pulling out the fixing tool from the tip of the long bolt, At this time, there has been a problem that the pair of elastic lock claws are scraped off by the screw surfaces and cannot be reused.

[0004]

In order to effectively solve the problem of such a conventional fixture, the present invention utilizes a spherical boss portion provided on the mounting base side to form a through hole in the mounting base. It was developed as a fixture for fixing a perforated plate material, and consists of a main member, a holding member, an operating member and a locking member, and the main member has the operating member and the locking member inside via spring pressure. A cylindrical main body that is vertically movably supported, a flange is provided at a substantially middle portion of the cylindrical main body, a guide elongated hole is formed on an upper side of the flange, and a screw part is formed on a lower side of the flange. The holding member includes a ring-shaped main body that holds the through hole edge of the plate member in cooperation with the flange of the main member, and forms a screw portion that is screwed with the screw portion at an appropriate position of the ring-shaped main body. , The ring-shaped body has a regulation part around the center opening, The member is provided with an operating head body projecting outward from the cylindrical main body of the main member, and one leg piece having a stopper projection facing the guide elongated hole and an original guide elongated hole are provided on the lower surface of the operating head body. The lock member includes a tubular main body having a stopper projection facing the guide elongated hole of the other leg, and the lower end of the tubular main body is provided with a slit. A structure is adopted in which the spherical boss portion is removably fitted into the lower end portion so that it can be expanded.

[0005]

According to the present invention, therefore, the lower side of the cylindrical main body of the main member, which previously supports the operating member and the lock member, is inserted into the through hole formed on the plate member side. ,
If the threaded portion of the tubular main body and the threaded portion of the holding member are screwed together, and the flange of the main member and the ring-shaped body of the holding member are held between the inner and outer edges of the through hole, the fixture itself Can be easily attached to the plate side. Therefore, this time, when the spherical boss portion is pushed into the tubular main body of the main member from the center opening of the holding member while pressing the operating head of the operating member, the other of the operating members is pushed by pushing the spherical boss portion. With the movement of the stopper protrusion in the guide elongated hole of the leg piece, only the lock member in the main member rises against the spring pressure, and the lower end thereof is formed at the central opening edge of the holding member. At the same time as allowing the spherical boss portion to expand into the lower end portion of the locking member while expanding apart from the restriction portion, the locking member lowers again due to the spring pressure, which causes the spherical boss portion to fall within the lower end portion of the locking member. The plate member is automatically fitted and firmly fixed to the mounting base.

When releasing the fixed state of the plate member, conversely, if only the operating head of the operating member is pulled, the stopper projection provided on one leg of the operating member is used as the main member. While moving in the guide long hole on the side, the operating member itself rises in the tubular main body of the main member.
The lock member facing the stopper projection in the guide elongated hole of the other leg of the operating member is also raised, and the lower end portion of the lock member is again formed with the regulating portion formed at the central opening edge of the holding member. This allows the spherical boss to automatically disengage from the lower end of the locking member as it is allowed to spread away from. Therefore, after that, if the fixing tool is held and the plate material is separated from the mounting base body in that state, the fixed state of the plate material can be easily released.
