安全、容易に行うことができるようにする点にある。In these conventional shade attachment structures, each locking piece provided on the instrument body is brought into contact with the annular engagement portion of the shade attached to the instrument body. As a result, the shade is retracted to the non-locking position, so that there is an advantage that the shade can be attached to the instrument body by a one-touch operation of pushing the shade into the instrument body side. However, according to the former case of the related art, when the shade is attached, the second inclined cam surface for releasing the lock formed on each locking piece prevents the annular locked portion of the shade from coming off and locking the shade. In order to prevent the falling of the
It is necessary to increase the elastic biasing force of each locking piece outward in the radial direction of rotation, and as a result, a large operating force is required even when removing the shade. Especially, since this kind of lighting equipment is installed on the ceiling surface, when removing the shade,
I will apply a detaching force downwards to the Sade,
As a result, depending on how the force is applied and how the shade is held, the shade may fall out of the hand as a reaction when the lock is released. Further, in the case of the latter of the related art, each locking piece on the instrument body side is brought to the non-locking position against the elastic biasing force by abutting with the unlocking cams provided at a plurality of positions of the shade. As the elastic biasing force of each locking piece is increased outward in the radial direction of rotation to enhance the fall prevention function, a large operating force is required to remove the shade, near the ceiling surface. The work of removing the shade, which is performed at a relatively high place, is likely to be unstable. The present invention has been made in view of the above-mentioned circumstances, and the object thereof is that while the work of attaching the shade can be performed by one-touch operation, the work of removing the shade is safe with a small operation force, The point is that it can be done easily.

ある。In order to achieve the above object, according to the present invention, there is provided a shade mounting structure for a lighting fixture in which a shade is attached to and detached from a fixture body and relatively rotatable. Locking pieces elastically projecting outward in the radial direction of rotation are provided at a plurality of positions on the shade mounting portion of the main body. A shade is formed by abutting the inclined cam surface that retreats the locking piece to the non-locking position against the elastic biasing force with the contact with the annular locking portion and the annular locked portion of the shade. A locking surface that locks the retainer is formed, and the annular locking portion of the shade allows the passage of the locking piece only when the shade is in a specific phase with respect to the instrument body. A notch for release is formed, and further, the device body and shade When the locking piece moves to the notch of the annular locking portion with relative rotation, a resistance applying means for applying rotational resistance to the shade is provided. The actions and effects of the are as follows.

る。[Operation] When the shade is attached to the instrument body, if the shade is pushed toward the instrument body, the annular locking portion of the shade is brought into contact with the inclined cam surface of each locking piece provided on the instrument body side. The respective locking pieces are retracted to the non-locking position against the elastic biasing force. Then, when the annular locked portion of the shade passes the locking piece, each locking piece again projects to the locking position by the elastic biasing force, and the annular locked portion of the shade contacts the locking surface of each locking piece. It is locked and held in the state that it does not come off. In addition, when removing the shade from the device body, when the shade is rotated with respect to the device body, rotation resistance is added by the resistance applying means immediately before the notch on the side of the shade moves to the locking piece, and the shade is removed. It is possible to perceptually recognize that the position has been reached. Then, when it is rotated a little from that state, the notch portion on the side of the shade and the respective locking pieces on the side of the instrument main body are aligned with each other, and the shade can be pulled out by its own weight.

に行うことができるようになった。Therefore, while the respective locking pieces provided on the instrument body side are biased by the elastic force capable of securely retaining and holding the shade, the rotation resistance due to the resistance applying means causes the rotation of the instrument body and the shade. It is sufficient that a minute one is sensuously recognizing that the locking piece moves to the notch of the annular locking portion with the relative rotation with respect to. Therefore, while the work of attaching the shade can be done with a one-touch operation by pushing in the same way as in the past, it is possible to reduce the operation force when removing the shade, and it is possible to perform relatively high places near the ceiling surface. It is now possible to safely and easily remove the shade.

If a stopper surface that abuts the locking piece transferred to the notch is formed at the portion of each elastic body facing the notch, the shade should be removed reliably and easily. There is an effect that can be. That is, when removing the shade, the rotating operation is performed while pressing the shade against the instrument body side, but at this time, the locking piece transferred into the cutout portion contacts the stopper surface of the elastic body and further rotation operation is not possible. Since it is blocked, the locking piece does not pass through the notch as it is, and the shade can be removed reliably and easily.

とができる効果がある。Further, as described in claim 3, the resistance applying means elastically attaches the locking piece within the range of the locking action area at positions near both ends of the notch in the rotation direction. When the projection is provided on the shade so as to retreat against the power, it has the following effect. That is, at the time of removing the shade, if the shade is pressed against the main body of the device and rotated, the protrusion provided on the shade causes the locking piece to retreat within the range of the locking action area against the elastic biasing force. It is possible to perceptually recognize that the shade has reached the removal position due to the increase in the rotation operation resistance at this time. Therefore, there is an effect that the resistance applying means for sensually recognizing that the shade has reached the removal position can be easily configured by utilizing the biasing structure of the locking piece.

Has the following effects. That is, since the projection on the side of the shade passes through the locking piece and at the same time, the locking piece projects again due to the elastic biasing force in the cutout portion, the protruding locking piece and the stopper for the projection located on the lower side in the rotation direction. When the surface touches, further rotation of the shade is blocked, and when the pressing force of the shade is released at that point, the shade will come out under its own weight. Therefore, the locking piece does not pass through the notch as it is, and the shade can be removed reliably and easily.
