Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover that requires opening and closing of lighting equipment.

[0002]

[Prior art]

 As shown in FIG. 4, the conventional spotlight cover opening / closing mechanism has vertical legs 6a and 7a at both ends of a mounting portion 5a provided at one end of the cover, and the legs of the legs 6a and 7a are provided with square holes of the main body 2a. 4a is provided with guide pieces 8a and 9a, and guide springs 8a and 9a are provided at the ends thereof with a leaf spring 3a having a shape of a return guide and locking pieces 10a and 11a in consideration of retaining. The cover 1a is fixed to the main body 2a 1 by inserting the locking pieces 10a, 11a of the leaf spring into contact with the end surface of the square hole 4a of the main body 2a.

[0003]

[Issues to be solved by the device]

 The above-mentioned conventional spotlight cover opening / closing mechanism can open / close the cover 1a with one touch, but the cover-1a vibrates due to an external impact, and the locking pieces 10a, 11a of the leaf spring 5a fixed to the cover-1a are released. There is a problem that the square hole 4a of the main body 2a tends to pull it inward so that it is easily removed. Further, when the fitting position between the cover 1a and the main body 2a is disengaged, there is a problem that the leaf spring 5a on the side of the main body 2a which is dislocated outside the square hole 4a is largely deformed when the cover -1a is opened. There is also a problem that light leaks from the gap between the square hole 4a of the main body 2a and the leaf spring 5a. The present invention has been made in view of the above point, and the purpose thereof is to open and close the cover 1a by a simple operation so that the cover 1a cannot be opened by an external impact and the square hole 4a of the main body 2a is not opened. The purpose is to provide a spotlight cover opening / closing mechanism that does not leak light from the component and that allows easy management of the dimensions of the components.

[0004]

[Means for Solving the Problems]

 It is provided on the mating surface of the main body, with a lock fitting that is provided on the cover and slides on the mating surface of the cover to fix the cover to the main body, a cover handle that is connected to the lock fitting with the cover in between. And a locking member for engaging with the locking body, the spotlight cover opening / closing mechanism comprises a stepped flat plate-shaped sliding portion and a rising portion for connecting with a slidable handle on the outer surface of the cover. The main body side fixed portion has an opening into which the tongue piece at one end of the slide portion of the lock fitting attached to the cover side is inserted, and the tongue piece at one end of the slide portion located at the bottom of the opening is attached to the main body. There is a leaf spring that presses against the back side of the mating surface of the lock fitting, and the tongue at one end of the sliding part of the lock fitting is inserted into the opening of the main body and the handle is slid to slide the one end of the sliding part of the lock fitting. tongue To solve the problem described above by fixing the the present body - a by holding between the back surface and the leaf spring mating surface of the body cover.

[0005]

[Action]

 With the above structure, the tongue piece of the cover locking metal piece is held between the back surface of the mating surface of the main body and the leaf spring even when an external impact is applied, so that the cover cannot be easily opened. Further, since the leaf spring blocks the opening of the fixing portion on the main body side, light does not leak from the opening.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. The spotlight cover opening / closing mechanism includes a lock fitting 7 provided on the cover-1 for fixing the cover-1 to the main body 2 by sliding along the mating surface of the cover-1 and the main body 2, and the lock fitting with the cover sandwiched therebetween. A cover handle connected to the main body 2 and a main body side fixing portion which is provided on the mating surface of the main body 2 and engages with the lock metal fitting 7.

As shown in FIG. 3, the lock metal fitting 7 has a rising portion 23 on the side surface of a stepped flat plate-shaped slide portion 20 and is fixed to the slide portion 12 of the handle 3 on the outer surface of the cover with the cover-1 interposed therebetween. The slide part 20 has a stepped tongue piece 22 at one end, a fitting hole 24 at the center of the tongue piece 22, and a fitting hole 21 at the other end of the slide part 20.

The main body fixing portion inserts the tongue piece 22 at one end of the slide portion 20 of the lock fitting 7 and the tongue piece 22 of the slide portion 20 located at the bottom of the square hole 4 into the main body 2 And a flat plate-shaped leaf spring 5 that presses the rectangular hole 4 to cover the square hole 4, and a hole 24 provided in a tongue piece 22 at one end of the sliding portion 20 of the lock fitting 7 at the sliding end of the lock fitting 7. It comprises a main body 2 having a hemispherical projection 9 to be fitted on the back surface 11 of the mating surface. The cover-1 is fitted on the back surface 10 of the mating surface with the square hole 6 into which the tongue piece 22 of the lock fitting 7 is inserted, and the hole 21 provided at the slide end of the lock fitting 7 at the end of the sliding portion 20 of the lock fitting 7. It has a protrusion 8 to be fitted, and has a slide hole of the slide portion 12 of the cover handle 3 on a side surface perpendicular to the mating surface 10.

In the assembled state, the handle 3 which is provided on the side surface of the cover 1 and in which the hole 21 of the lock fitting 7 and the protruding portion 8 of the cover 1 are fitted together is rotated toward the main body to move the lock fitting 7 The tongue piece 22 of the main body 2 is inserted into the square hole 4 of the main body 2, and when the mating surface of the cover 1 and the mating surface of the main body are in contact with each other, the cover handle 3 is slid so that the tongue piece 22 of the lock fitting 7 is The cover 1 is fixed to the main body 2 by holding the cover 1 between the back surface 11 of the mating surface and the leaf spring 5 and fitting the hole 22 of the lock fitting 7 into the protrusion 9 of the main body 2.

[0010]

[Effect of device]

 In the spotlight cover opening / closing mechanism according to the first aspect, since the cover 1 and the main body 2 are fixed by the lock fitting 7, the cover is not opened due to an external impact. Further, when the cover 1 is closed, the leaf spring 5 fixed to the main body 2 receives the tongue piece 22 of the lock fitting 7, so that the impact due to the collision between the lower end surface of the cover 1 and the lower end surface of the main body 2 is absorbed. Since the leaf spring 5 has a wider space than the square hole 4, light leakage from the square hole 4 is prevented. In the spotlight cover opening / closing mechanism according to claim 2, when the lock is attached / detached, the resistance of the fitting between the projections 8 and 9 provided on the rear surface of the cover and the body mating surface and the holes 21 and 22 of the lock fitting 7 changes. Therefore, it is possible to judge the lock attachment / detachment by the touch. Further, since the hole 21 of the lock metal fitting 7 is fitted into the protrusion 8 of the cover 1 in a state where the lock metal fitting 7 is removed from the main body side fixed portion, the lock metal fitting 7 is not displaced.
