Description

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

[Background Art] Conventional globe mounting structures for this type of lighting equipment include, for example, one in which the center of the lower surface of globe A is supported by a thumbscrew B, as shown in FIG.
Or, as shown in Fig. 7, the glove holder C
In some cases, the glove A can be removed by loosening the screw D that secures it 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 against this problem, in the case of the one in Fig. 7, an auxiliary piece E is provided on the glove holder C as shown in Fig. 7b, and the glove A is once received by this auxiliary piece E before being removed. Although this prevents the lamp from falling, there was a problem in that the procedure for removing the lamp was complicated and replacing the lamp was time-consuming.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to attach a glove to a chandelier-type lighting device that allows the user to put on and take off the glove while holding the glove with both hands. It is there to provide structure.

[Disclosure of the invention] Accordingly, the present invention is such that the base end of the globe holder 3 is horizontally rotatably supported on the upper surface of the peripheral part of the mounting plate 2 whose central part is suspended and the lamp 1 is mounted on the lower surface. The tip of the glove holder 3 is made to protrude outward beyond the periphery of the mounting plate 2, and the periphery of the cover body 4 attached to the upper side of the mounting plate 2 and the tip are connected to the glove edge and the above. A long hole 6 is formed along the longitudinal direction in the middle part of the glove holder 3, and an arc-shaped hole 6 is formed along the circumferential direction in the peripheral part of the mounting plate 2. A pin 8 protruding from the lower surface of the cover body 4 is passed through the hole 7, and by rotating the cover body 4 and rotating the glove holder 3 with the pin 8, the tip of the glove holder 3 is inserted. In a globe mounting structure for a lighting device in which a part can be freely engaged with and disengaged from an inner edge of a globe 5, a lock fitting 10 is attached to an intermediate part of a lock fitting 10 which is slidably contacted with the lower surface of a mounting plate 2 horizontally around the pin 8 as an axis. , a protrusion 10b is formed which engages with the edge of the mounting plate 2 or the engagement hole 13 provided in the mounting plate 2 when the glove holder 3 and the glove 5 are engaged and disengaged. An upwardly bent piece 10a provided at the tip protrudes upward from a through hole 12 provided in the cover body 4, and by holding the glove 5 and the cover body 4 between both hands and rotating them together,
The glove holder 3 is characterized in that it can be easily engaged with or disengaged from the inner edge of the glove 5, and that it can be locked in the engaged or disengaged state.

[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. Note that a collar body 14 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 the receiving metal fitting are connected. 3 and 3, an elastic force is applied to pinch the inner edge portion 5a of the glove, so that it is also possible to attach gloves 5 having inner edge portions 5a of different thicknesses. Further, in FIGS. 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. The upper bent piece 10a at the other end protrudes upward from the through hole 12 provided in the cover body 4 to serve as a lock release operation part, and the glove 5 is locked to the glove holder 3. In this state, as shown in FIGS. 1 and 5, the protrusion 10b formed at the intermediate portion engages with the notch 2a provided at the edge of the mounting plate 2, and as shown in FIG. As shown by the imaginary lines in , when the glove 5 is detached from the glove holder 3, the protrusion 10b engages with the engagement hole 13 formed in the mounting plate 2, and in each state. The cover body 4 is designed to be locked. If it is desired to release the locked state, the upper bent piece 10a protruding from the upper surface of the cover body 4 may be slightly pushed down with a finger. Further, as shown in FIG. 4b, if the engagement side of the protrusion 10b is provided with an inclination angle α, the engagement with the edge of the mounting plate 2 can be made more secure.

[Effects of the invention] As described above, in the present invention, the tip of the globe holder pivoted around the periphery of the mounting plate can protrude or retract outward from the periphery of the mounting plate, and this tip and the cover body The inner edge of the glove is sandwiched between the inner edge of the glove and the peripheral edge of the glove so that the glove can be freely engaged and disengaged, and a cover is provided in the long hole provided in the glove holder and the arc-shaped hole provided in the mounting plate. A pin protruding from the underside of the body is passed through and the glove holder is rotated by this pin when the cover body is rotated, so the glove can be rotated by holding the glove together with the cover body with both hands. This has the advantage that lamp replacement work can be done easily, as there is no need to operate the screws while supporting the glove with one hand as in the conventional method. Since a protrusion is formed that engages with the edge of the mounting plate or the engagement hole provided in the mounting plate when the receiving bracket and the glove are engaged and disengaged, there is no risk that the glove once engaged may fall due to vibration etc. In addition, there is an advantage that there is no risk of the glove holder fitting rotating with the glove removed and causing trouble in putting on the glove.
