Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a connection device that improves the workability of connection and that can be used selectively depending on the type of ceiling rosette.

(Prior art) Conventionally, when hanging lighting equipment from a ceiling, an exposed ceiling rosette, for example, is attached to the ceiling, and a removable ceiling cap is attached to the rosette. Electrical connections and hanging of the lighting fixtures were made through the. In addition, in order to ensure the safety of hanging heavy lighting equipment, a separate hook is attached to the ceiling surface, and the hanging cord is secured to this to suspend the fixture. As disclosed in Japanese Patent No. 60385, there is known a structure in which a locking member for locking a hanging cord protrudes from the lower surface of a ceiling cap. however,
In the former case, it is necessary to attach the parts separately, which is economically disadvantageous and also impairs workability.In the latter case, the locking member is exposed, resulting in poor appearance and the same problem. There is also the problem that the fixtures become slanted and rotate, making it difficult to align them with the direction of the room.

(Problems to be solved by the invention) As mentioned above, attaching a hook to the ceiling when hanging a lighting fixture is less economical and less workable, and it is also necessary to provide a locking member protruding from the ceiling cap. is inferior in appearance and causes trouble in operation.

Therefore, the present invention was devised to eliminate the above-mentioned problems, and to provide a connecting device that can be used for different purposes regardless of whether the ceiling rosette is an exposed type or a recessed type, and also allows for easy connection work. The purpose is to provide.

[Structure of the idea]

(Means for Solving the Problems) In the connecting device of the present invention, a sealing cap is removably attached to a ceiling rosette and has an engaging portion protruding from its lower surface, and an insertion hole corresponding to the engaging portion is formed in the sealing cap. In addition to providing a ceiling cover with a ceiling rosette, if the ceiling rosette is an exposed type, the engaging part protrudes from the insertion hole of the cover, and if the ceiling rosette is a recessed type, the engaging part is housed. It is configured by placing the

(Function) When suspending an instrument with an exposed ceiling rosette, an engaging part with a pair of hooks is attached to the bottom surface of the sealing cap attached to the ceiling rosette, and an engaging part with a pair of hooks is attached to the ceiling cover. The connection cord led out from the cap is inserted into the cord insertion hole provided on the inner bottom surface of the cap, and the engagement portion is protruded from the insertion hole opposite to the engagement portion, and the connection cord is provided upright on the inner circumferential side of the cord insertion hole. By tightening the connection cord at the stop, the ceiling cover can be fixed and the periphery of the opening can be brought into close contact with the ceiling surface. Therefore, there is no need to provide a special hook on the ceiling surface, the appearance is good, and the device can be prevented from rotating. In addition, in the case of a recessed ceiling rosette, if the appliance is suspended by the locking claws attached to the rosette and the opening periphery of the ceiling cover is tightly fixed to the underside of the ceiling rosette, the sealing cover can be attached to the ceiling cap and its underside. Since the engaged portion is housed within the sealing cover and is not exposed to the outside, the installation operation is extremely easy and the appearance is excellent.

(Example) Hereinafter, details of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a rectangular hanging ceiling rosette, which is attached to a ceiling surface 2. 3 is a sealing cap that is detachably attached to the ceiling rosette 1;
The locking contact pieces 4 shown in FIG. An electric cord 5 connected to the cap 4 is led out from a screw hole 6 provided at the center of the lower surface of the cap 3. Reference numeral 7 denotes an engaging portion, and a ring-shaped base plate 10 has a through hole 9 at the top for insertion of the cord 5 and mounting screw 8.
and a pair of locking legs 12, 12 which extend downward from the edge and have curved hooks 11, 11 at their tips, and are mounted by means of mounting screws 8 so as to protrude from the lower surface of the cap 3. It is worn. Reference numeral 13 designates a cylindrical sealing cover with a bottom, the bottom surface of which is provided with insertion holes 14, 14 through which the locking legs 12, 12 can be inserted, at positions opposite to the locking legs 12 of the engaging portion 7 ; The central part has a locking part 17 that is elastically divided by an insertion hole 15 for the cord 5 and a slit 16 that stands inward from the periphery thereof. The sealing cover 13 can be fixed in an appropriate position by tightening the cord 5.
A pair of ribs 18 project from the inside of the cover 13 and are fitted into the sealing rosette 1 and the cap 3 to prevent the sealing cap 3 from undesired rotation. Reference numeral 19 denotes a lighting fixture that is suspended by a hanging fixture 21.

FIG. 2 shows the mounting structure of the ceiling cover 13 when the ceiling rosette 1' is of a recessed type, and other parts that are the same as those in FIG. 1 are given the same symbols. Since the locking claws 20, 20 for hanging the instrument 19 are attached to the rosette 1' in advance, the hanging tool 21 is attached to the locking claws 20 and the instrument 19 is suspended. Therefore, if the sealing cover 13 is installed so as to accommodate the sealing cap 3 and the engaging part 7 , and the cord 5 is tightened at an appropriate position by the locking part 17, the sealing cover 13 is closed.
can be fixed to the lower surface of the rosette 1'.

[Effect of idea]

As detailed above, the present invention includes a sealing cap that is removably attached to a ceiling rosette, an engaging portion protruding from the bottom surface of the cap, and an insertion hole provided at a position opposite to the engaging portion. A sealing cover is a connecting device formed so that the engaging part protrudes from the insertion hole when the ceiling rosette is an exposed type, and the engaging part is housed when the ceiling rosette is a recessed type. Because of this, it is possible to use different types of ceiling rosettes, such as exposed or recessed types, and they can be protected by the same ceiling cover, and it is economical because there is no need for separate locking fittings. Improved workability can also be obtained. Furthermore, in the case of the exposed type, the hanging tool of the instrument can be locked to the engaging portion protruding from the lower surface of the cover, which increases safety and prevents the instrument from rotating. Note that fine adjustment of the direction of the instrument can be performed by rotating the engaging portion.

In addition, when using a recessed rosette, the device can be hung by the hook on the rosette, so the protruding engagement part can become a nuisance and cause trouble, but since it can be stored inside the ceiling cover, the appearance It has various advantages such as improved performance.
