Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a certification device in which a shade is rotatably attached to an arm.

[Conventional technology]

Conventionally, as shown in FIGS. 5 and 6, a hinge 61 for vertical rotation is provided on an arm 51, a support shaft 54 is protruded from a movable member 53 of the hinge 61, and a shade 57 is One that is rotatably mounted has been proposed. The hinge 61 is attached to the arm 51
A receiving member 52 fixed to the receiving member 52 and a fixing screw 55
And a movable member 53 rotatably mounted with a nut 56.

The support shaft 54 is loosely fitted in the mounting hole 58 of the shade 57 and is fastened with a nut from the inside of the shade 57. The movable member 53 has a stopper pin 60 which is loosely fitted in an arc-shaped stopper groove 59 provided on the shade 57, and the rotation of the shade 57 is stopped at a predetermined rotation angle.

[Problems to be solved by the invention]

In the above configuration, the stopper pin 60 is likely to be broken because the expanded force is applied when the shade 57 is rotated by a human hand.

In addition, there is a problem that the provision of the stopper pin 60 increases the size of the hinge 61 and deteriorates the appearance. Also,
When the seed 57 is rotated, the stopper groove 59 is visible from the outside, which also deteriorates the appearance.

It is an object of the present invention to provide a certification device which can increase the strength of a stopper portion for stopping rotation of a shade and has a good appearance without the rotation stopping means being visible from the outside.

[Means for solving the problem]

This invention has a shade mounting body in which a male spindle is formed on the outer periphery and a tubular spindle is inserted and a lead wire is inserted inside, and a mounting hole through which the spindle penetrates is provided on both sides of the mounting hole on the inner surface. A shade having a pair of grooves, an outer surface of which is in contact with the shade attachment body, a U-shaped reinforcing member having a through hole through which the support shaft penetrates and a bent piece fitted at each end with the groove,
A first nut that is screwed to the support shaft and fastens the shade to the shade mounting body via the reinforcing member; and a hole having a shaft through which the support shaft is rotatably inserted, the end of which is an outer shell of the shade. A stopper that engages with the inner surface of itself and prevents rotation of the shade beyond a predetermined rotation angle, and a second screw that is screwed to the support shaft and clamps and fixes the stopper between the first nut. And two nuts.

[Action]

According to the structure of the present invention, since the stopper is engaged with the inner surface of the outer shell itself of the shade, the structure can be made relatively simple, and the stopper can be formed large to improve the strength. In addition, since the stopper is hidden inside the shade and cannot be seen from the outside, the appearance is improved. Second
Since the rotation of the stopper is restricted by tightening the nut, the shade can be fixed at an arbitrary rotation angle, and the stopper can rotate around the support shaft even if a strong force is applied to the shade. Parts are less likely to be damaged or damaged.

〔Example〕

One embodiment of the present invention will be described with reference to FIGS.

The seed 1 comprises a cylindrical upper shade 1A and a bowl-shaped lower shade B, and a decorative ring 7 is provided on the lower edge. Sade 1
The socket 3 of the lamp 2, the reflection plate 4, and the outer cylinder 5 are housed in a block, and attached to the lower shade 1 </ b> B with screws 6.

The arm 8 has a pipe shape, and a movable member 10 serving as a shade attachment body is mounted on the upper end so as to be rotatable up and down around a horizontal axis 9, and a threaded cylindrical support shaft 11 is protruded from the movable member 10. Support shaft 11
Is inserted into the mounting hole 19 on the side surface of the upper shade 1A, and the reinforcing bracket 12 and the washer 13 as the reinforcing tools are passed through the support shaft 11. By tightening the side portion of the upper shade 1A with the first nut 14 together with the reinforcing metal fitting 12 and the washer 13, the upper shade 1A is attached to the support shaft 11 so as to be vertically rotatable. The lead wire 17 of the socket 3 is inserted into the support shaft 11 and the arm 8, and is connected to the instrument body at the base end of the arm 8.

A stopper 16 is further inserted through the support shaft 11, and the stopper 16 is fixed by being sandwiched between the first nut 14 and the second nut 15 on the distal end side. The stopper 16 engages with the inner surface of the top plate 1a of the outer shell of the upper shade 1A to stop the rotation of the shade 1. As shown in FIG. 3, the stopper 16 is made of a substantially T-shaped plate material. A hole 16a is formed. The reinforcing bracket 12 is made of a plate material, and the bent pieces 12a provided on both side edges are
Freely fit between 7,18.

According to this configuration, the shade 1 can rotate up and down around the horizontal axis 9 with respect to the arm 8 and can also rotate around the support shaft 11 perpendicular to the horizontal axis 9. Thereby, the shade 1 can rotate in an arbitrary direction.

The range of rotation of the seed 1 around the support shaft 11 is regulated as follows. That is, as shown by the chain line in FIG. 4, when the shade 1 faces directly below, the stopper 16
Apart from 1A, the shade 1 can rotate freely. When the upper shade 1A turns 90 ° as shown by the solid line in the figure and turns to the side, the top plate 1a of the upper shade 1A engages with the tip of the stopper 16 and further rotation of the shade 1 is stopped. Will be blocked.

According to this lighting fixture, since the stopper 16 is engaged with the inner surface of the outer shell itself of the shade 1, the structure can be made relatively simple and the stopper 16 can be formed large to improve the strength. Further, since the stopper 16 is hidden inside the shade 1 and cannot be seen from the outside, the appearance is improved. Further, since the rotation of the stopper 16 is restricted by tightening the second nut 15, the shade 1 can be fixed at an arbitrary rotation angle, and even if a strong force is applied to the shade 1, the stopper 16 can rotate the support shaft 11.
It is possible to rotate around the instrument, so that the instrument parts are hardly damaged or damaged.

[Effect of the invention]

The lighting fixture of the present invention has a structure in which the stopper is engaged with the inner surface of the outer shell itself of the shade, so that the structure can be made relatively simple and the stopper can be formed large to improve the strength. In addition, since the stopper is hidden inside the shade and cannot be seen from the outside, the appearance is improved. Furthermore, since the rotation of the stopper is restricted by tightening the second nut,
Since the shade can be fixed at an arbitrary rotation angle and the stopper can rotate around the support shaft even when a strong force is applied to the shade, breakage or damage of the instrument parts is hardly caused.
