Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a globe mounting structure for a chandelier type lighting fixture in which a glass globe is covered with a round fluorescent lamp.

[Background Art] Conventional globe mounting structures for this type of lighting equipment include, for example, as shown in FIG. 7, the center of the lower surface of the globe A is supported by a thumbscrew B, or as shown in FIG. In some cases, the glove A can be removed by loosening the screw D that fixes the glove holder C and sliding it in the direction of the arrow.
However, in all of these structures, when removing screws B or D, it is necessary to hold glove A with one hand, and since glove A cannot be held with both hands, there is a risk of the glove falling. As a countermeasure for this, in the model shown in Fig. 8, an auxiliary piece E is provided on the glove holder C as shown in Fig. 8b, and the glove A
This was done by supporting the lamp with the auxiliary piece E before removing it to prevent the lamp from falling due to inadvertence, but this made the removal procedure complicated and the lamp replacement took much time and effort.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to provide a glove mounting structure for a chandelier type lighting device that allows the glove to be attached and removed while holding the glove with both hands. There is something to do.

[Disclosure of the invention] Therefore, the globe mounting structure of the lighting equipment according to the invention includes a mounting plate 2 on which the lamp 1 is mounted on the lower surface;
A globe holder 3 whose base end is pivoted around the periphery of the mounting plate 2 and can be rotated horizontally, and the mounting plate 2
a cover body 4 which is horizontally rotatably attached to the upper side and which holds the inner edge of the glove 5 between the tip of the glove holder 3 that protrudes outward from the periphery of the attachment plate 2; and the attachment plate. 2. The upper bent piece 10a at the tip is horizontally rotatable on the lower surface of 2.
The cover body 4 includes a locking fitting 10 that protrudes upward through a through hole 12 provided in the cover body 4. A pin 8 is provided protruding from the periphery to pass through a long hole 7 provided along the circumferential direction, and when the glove holder 3 rotates as the cover body 4 rotates, the tip of the glove holder 3 is rotated. The lock fitting 10, which rotates integrally with the cover body 4, has an engaging portion with a downwardly bent piece 13 provided on the edge of the mounting plate 2. The glove 5 and the cover body 4 can be separated from the lower bent piece 13 by pressing down the upper bent piece 10a. The glove holder 3 can be easily removed from the inner edge of the glove 5 by rotating the two together.

[Example] Fig. 1 is a bottom view of the lighting fixture according to the present invention, Fig.
The figure shows a longitudinal cross-sectional view. The mounting plate 2, which constitutes the main body of the instrument with the lamp 1 attached to its lower surface, has its central part suspended from the tip of the arm 9, and the peripheral part of the mounting plate 2. The base end of the glove holder 3 is horizontally rotatably supported on the upper surface, and the tip 3a of the glove holder 3 protrudes outward beyond the periphery of the mounting plate 2 and is placed on the upper side of the mounting plate 2. The peripheral part of the cover body 4 attached so as to be horizontally rotatable and the glove holder 3
The inner edge portion of the glove 5 is held between the tip portion 3a and the tip portion 3a. A long hole 6 is provided in the middle part of the glove holder 3 along its longitudinal direction, and an arcuate hole 7 is provided in the peripheral part of the mounting plate 2 along the circumferential direction. A pin 8 is provided to protrude from the lower surface of the cover body 4 and extends through the arcuate hole 7 .

FIG. 2 shows a cross section taken along the line A-A' in FIG. 1, and the inner edge 5a of the glove 5 is held between the peripheral edge of the cover body 4 and the tip 3a of the glove holder 3. In this state, when the glove 5 and cover body 4 are held between both hands and rotated horizontally, the glove holder 3 rotates to the position shown by the two-dot chain line in FIG. Since the glove 5 is disengaged from the inner edge 5a of the glove, the glove 5 can be removed downward. FIG. 3 shows this state, that is, a cross section taken along line BB' in FIG. In addition, in Figures 1 and 2,
R ₁ indicates the inner diameter of the inner edge portion 5a of the glove, and R ₂ indicates the inner diameter of the hanging peripheral wall 4a of the cover body 4.

The tip part 3a of the glove holder 3 has the markings shown in Fig. 4a.
As shown in FIG. 3, a stepped portion is formed on which the inner edge portion 5a of the glove is placed, and a stepped portion is formed on the periphery of the mounting plate 2 to prevent the glove holder 3 from lifting off the top surface of the mounting plate 2. A matching cut-and-raised piece 3b is provided. FIG. 4b shows a locking fitting 10 for locking the cover body 4 against accidental rotation while holding the glove 5. A pin 8 is inserted into the shaft hole 11 provided at one end of the locking fitting 10. passes through the upper bent piece 10a and projects upward from a through hole 12 provided in the cover body 4 at the other end, and as shown in FIGS. 1 and 5, the upper bent piece 10a and the side edge 10b are the hole 12 of the cover body 4 and the lower bent piece 1 of the edge of the mounting plate 2, respectively.
3, the cover body 4 is locked. When it is desired to remove the glove 5, the upper bent piece 10a is pushed down slightly, so that the lock fitting 10 gets over the lower bent piece 13 and becomes freely rotatable, releasing the locked state.

Further, a collar body 114 is formed by fitting an E-ring to the lower end of the pin 8, and by interposing a compression spring 15 between the collar body 14 and the mounting plate 2, the cover body 4 and Attach the inner edge of the glove to the bracket 3.
An elastic force is applied to pinch a. Therefore, as in the embodiment shown in FIG. 6, it is also possible to attach gloves 5 whose inner edge portions 5a have different thicknesses.
The compression spring 15 is adapted to push up a lock fitting 10 which is disposed on the lower surface of the mounting plate 2 and is pivotally supported by a pin 8.

[Effects of the invention] As described above, in the present invention, when the cover body rotates, the glove holder also rotates, so that the tip of the glove holder engages and disengages from the inner edge of the glove. The glove can be put on and taken off simply by holding the glove together with the cover body in both hands and rotating it, and there is no need to operate the screws while supporting the glove with one hand as in the past.
In order to securely support the glove and prevent it from falling, and to prevent the cover body from inadvertently rotating, it is necessary to press down on the upper bent piece of the locking metal fitting to disengage the locking metal fitting from the mounting plate. Since the lamp cannot be rotated, there is an advantage that lamp replacement work can be performed easily and safely.
