Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical appliance mounting device for mounting an electrical appliance such as a lighting fixture on an appliance mounting piece of a ceiling rosette arranged on a mounting surface such as a ceiling.

For example, Utility Model Application No. 48-14888 and Utility Model Application No. 14888
As shown in Japanese Patent No. 48-14889, it is known that a lighting fixture is fixed to a fixture mounting piece of a ceiling rosette with screws. However, with these devices, the top surface of the lighting fixture is in contact with the ceiling rosette and the fixture mounting piece is screwed, so there is no space between the lighting fixture and the ceiling surface.
Especially in the case of elongated lighting equipment, a gap occurs over a long distance, giving the user a sense of uneasiness, and when the pull cord of the bull switch is operated, the lighting equipment oscillates, creating an even more uneasy feeling. There is a risk. On the other hand, as shown in Japanese Utility Model Application Publication No. 52-22687, a lighting fixture can be stably mounted by press-contacting the mounting portion at the top of the fixture to the mounting surface by operating an operating tool provided inside the fixture. There are known devices that prevent the above-mentioned fluctuation problem from occurring. However, in this case, the annular part of the support member having an annular part at the tip is engaged with one pawl fixed to the ceiling, and the top of the lighting fixture is inserted into the threaded part at the other end of the support member, and the above-mentioned screw is screwed. The lighting fixture is fixed by pressing it against the ceiling using a wing nut inserted through the ceiling. Therefore, this product cannot be installed on the ceiling using the existing hook ceiling on the mounting surface such as the ceiling. Moreover, since it is only fixed in one place with a screw, it has the disadvantage that it cannot be fixed firmly enough. Additionally, when installing the lighting fixture, the mounting part of the lighting fixture cannot be held in a temporarily fixed state, and the lighting fixture must be supported from below and then suddenly fixed to the mounting surface using the operating tool, so it is necessary to determine the direction of the lighting fixture. This makes the installation work troublesome.

The present invention has been made in view of the above circumstances, and has a through hole in the upper surface portion through which the ceiling rosette main body and the appliance mounting piece are inserted, and a storage area for the ceiling rosette body and the appliance attachment piece inside. a pair of frame portions disposed on the inner surface of the upper surface portion in the vicinity of the through hole;
a support having one end movably supported by the frame and having an engaging part engaging with the mounting piece at the other end; The electric appliance can be fixed to the ceiling surface in pressure contact with the support, and the installation can be easily performed by adjusting the operating tool. It is an object of the present invention to provide an improved appliance mounting device.

Reference numeral 1 denotes a sealing rosette main body, which is formed into a disc shape having plug blade insertion holes 2, 2 on its surface, and is disposed on a mounting surface 3. 4,4'
are a pair of U-shaped instrument attachment pieces that are attached to both ends in the diametrical direction and are made up of a plurality of pieces that protrude laterally from the main body 1, and are spaced apart from the attachment surface 3 and extend along the attachment surface 3. But this side 3
The open sides are facing each other. Reference numeral 5 denotes an electric appliance, which has a linear downward protrusion 5a in the center of its upper surface and has a through hole 6 through which the sealing rosette main body 1 and appliance attachment pieces 4, 4' are inserted. Moreover, it has a storage section 7 for the main body 1 and the instrument attachment pieces 4, 4' inside. 8
are a pair of frame portions disposed on the inner surface of the upper surface of the electric appliance 4 in the vicinity of the through hole 6, and protrude downward from the upper surface to form a space 9. 10,
Reference numeral 10 denotes a pair of supports, which are formed in an L-shape, one end of which is inserted into the space 9 of the frame 8, and supported by the frame 8 so as to be movable in the vertical direction. The other end of this is an engaging portion 11 consisting of a ring body.
which engages with the mounting pieces 4, 4'. The inner and outer diameters of the engaging portion 11 made of this ring body are the fifth diameter.
As shown in the figure, for example, the distance between the inner surfaces of the outer pieces 4a, 4'a of the U-shaped instrument attachment pieces 4, 4' is a, the distance between the outer surfaces is c, and the inner pieces 4b, 4'
When the distance between the outer surfaces at b is defined as b, the outer diameter of the engaging portion 6 is set to be smaller than a, and the inner diameter is set to be larger than b/2+c/2.

Reference numeral 12 denotes an operating tool, and this operating tool 12 is made of a screw, for example, and has a threaded part 13 inserted into the middle part of the supporter 10, and further inserts the tip of this threaded part 13 into the through hole 14 against the protrusion 5a. It is formed by being irremovably attached. The electric appliance 5 is, for example, a lighting device, and is formed to include a box-shaped body and a straight tube fluorescent lamp 15 installed within the body. 17 is switch, 18 is switch 17
It is a hook ceiling connected to.

Next, we will discuss the effect. The electrical appliance 5 is attached to the mounting surface 3 in the following manner. As shown in FIG. 2, supports 10, 10 are attached to the ceiling rosette main body 1, which has been previously attached to the mounting surface 3, in which the electric appliance 5 is mounted, for example, in a direction perpendicular to the protruding direction of the appliance attachment pieces 4, 4'. The engaging portion 11 is engaged with the mounting piece portions 4, 4' so as to be in the same position. When engaging, first, as shown in the fifth figure, the engaging part 1
If one side of the mounting piece 4 is placed close to the outer surface of the inner piece 4b of the other mounting piece 4, the other side can pass through the outer surface of the outer piece 4'a of the other mounting piece 4'. 'a can be viewed above. Therefore, if one side is pulled toward the outer piece 4a as shown in FIG.
The mating is completed. That is, if the outer diameter of the ring of the engaging part 11 is larger than the distance a between the inner surfaces of the outer pieces 4a, 4'a of the instrument attachment pieces 4, 4', the grooves of the attachment pieces 4, 4' Since it cannot be engaged, its outer diameter needs to be smaller than dimension a. The inner diameter of the ring of the engaging portion 11 is smaller than the sum of 1/2 of the distance c between the outer surfaces of each of the outer pieces 4a and 4'a and the distance b between the outer surfaces of each of the inner pieces 4b and 4'b. If there is, even if a part of the engaging portion 6 is placed on one mounting piece 4 and pulled toward the inner piece 4b when the engaging portion 6 is engaged, the other mounting piece 4'
Since the outer piece 4'a of the holder cannot be passed through, engagement is also not possible. Therefore, the inner diameter of the engaging portion 11 must be larger than b/2+c/2. Further, the directionality of the electric appliance 5 is determined by the support 10,
If the portions of the engaging portion 11 other than the attachment portion 10 are appropriately selected, they can be set arbitrarily. Next, by operating the operating tool 12, the electric appliance 5 can be gradually raised and brought into contact with the mounting surface 3 as the threaded portion 13 is screwed in, as shown in the fourth figure.
