[Prior art]
As a fixing tool that can be attached and detached with one touch, the one described in Japanese Utility Model Laid- Open No. 55-113620 is known. The one-touch type fixing tool described in this publication is effective as a fixing tool for attaching a wire mesh to a window glass of a vehicle, etc., and attaching sockets (female joints) to approximately four corners of the wire mesh, A socket (male joint) is fixed on the vehicle side, positioned around the vehicle window, and the socket body housing chambers attached to the four corners of the wire mesh are aligned with the plug fixed on the vehicle side. When the main body is pressed against the vehicle side, the plug enters the storage chamber and engages with a ball protruding into the socket main body storage chamber. When the metal mesh is further pressed in this state, the plug resists the spring provided in the storage chamber. Thus, the movable body moves and the ball engages with the engaging portion formed on the plug body, so that the socket and the plug can be connected. In order to remove this connection state, the plug can be removed from the socket by pulling out the operation member provided on the socket side.
[0003]
[Problems to be solved by the invention]
However, the fixing tool as described above may be operated in the pushing direction when connecting and fixing the plug and the socket, but when separating the both, an operation of pulling the operation member provided on the socket is required, For example, when such a fixture is applied to a cover of a large luminaire mounted on the ceiling, for example, when removing the luminaire, two workers hold the both ends of the luminaire cover while holding the operation member of the fixture. There is a problem that it is necessary to perform an operation of pulling, and it is difficult for a single operator to easily remove the cover of the lighting fixture. In addition, the movable body of the socket must be placed in a state of protruding from the surface of the cover, which is not suitable for a place where lighting is important because the aesthetics are impaired and the influence of the movable body occurs.
[0004]
Therefore, the present invention provides a fixing tool that can connect and fix the plug and the socket only by the operation in the pushing direction, and can separate the plug and the socket by the same pushing operation again. It aims at solving.
In the present invention, the plug and socket can be connected and fixed by the initial pressing operation, and both can be easily separated by performing the same pressing operation on the fixture in the connected state. For this reason, when this fixing tool is used for a large luminaire, the cover of the luminaire can be easily removed from the ceiling by one worker, and the cover can be easily attached to the luminaire by one worker. Therefore, it is possible to easily clean the luminaire or replace the fluorescent lamp.
[0005]
