Description

  The present invention relates to a mounting device for a ceiling-embedded device for mounting a device on a ceiling.

  In recent years, it has become widespread to install equipment on the ceiling surface embedded in the ceiling of a building, and there has been an increasing demand for equipment for mounting equipment with good workability that can easily reinforce the ceiling opening for installing the equipment. Yes.

  Conventionally, what was disclosed by patent document 1 was known as this kind of attachment apparatus.

  Hereinafter, the configuration will be described with reference to FIGS. 11 and 12.

  As shown in the figure, a plate-shaped scissor fitting 101 having a hole 101a formed in the center is provided so as to be foldable into two by forming hinge portions 102 on both sides across the hole 101a. Is folded into two and inserted from below into an embedding hole 103 for device placement formed in the ceiling 104, spreads on the upper surface of the ceiling 104, and the temporary fixing piece 105 is folded along the cut surface of the embedding hole 103. The scissors fitting 101 is temporarily fixed in the embedding hole 103.

  Then, the base 107 having an opening 107a formed at the center and to which equipment (not shown) is attached is tightened by screwing the mounting screw 106 into the screw hole 101b of the scissor fitting 101, and the flange 107b of the base 107. By sandwiching the ceiling 104 with the scissors fitting 101, the base 107 on which the device is mounted is disposed in the embedding hole 103 of the ceiling 104.

Japanese Utility Model Publication No. 5-11718 (paragraphs 0006 to 0009, FIG. 1 and FIG. 3B)

  In such a conventional apparatus for mounting a ceiling-embedded instrument, the scissor fitting 101 has to be formed with a hinge portion 102 for folding, and the construction becomes complicated. After insertion, the workability is poor because it must be spread on the top surface of the ceiling 104.

  The present invention solves such a conventional problem, and is an attachment device provided on a peripheral upper surface of a ceiling attachment opening to which a ceiling-embedded device is attached. The attachment opening has a simple configuration. An object of the present invention is to provide an attachment device that can reinforce the periphery of the machine and has good workability.

  In order to achieve this object, the ceiling-mounted device mounting apparatus of the present invention has a mounting opening for mounting the device with a flat mounting plate and a device in which an opening for inserting the device is formed in the center. A mounting device for sandwiching the formed ceiling, wherein the mounting plate is formed with a cut portion connecting an outer peripheral end portion and the opening, and the cut end portions forming the cut portion are separated from each other to form one cut From the end, it is inserted into the mounting opening of the ceiling and is placed on the upper surface of the ceiling, thereby achieving the intended purpose.

  According to the present invention, the flat mounting plate in which the opening for inserting the device is formed in the central portion is formed with the cut portion connecting the outer peripheral end portion and the opening, and the cut end portions forming the cut portion are formed between the cut end portions. And by inserting into the ceiling mounting opening from one cut end and placing it on the top surface of the ceiling, the periphery of the ceiling mounting opening can be reinforced with a simple configuration, The effect which provides the attachment apparatus of the apparatus with the effect that workability improves can be acquired.

Mounting apparatus ceiling-mounted device of the present invention is a mounting apparatus for clamping by a flat mounting plate and the device forming an opening for inserting the device into the central portion, the ceiling forming a mounting opening of the device The mounting plate is formed with a cut portion connecting an outer peripheral end portion and the opening, the cut end portions forming the cut portion are separated from each other, and the ceiling plate is mounted from one cut end portion. It is configured to be inserted into the opening and placed on the top surface of the ceiling, and the mounting plate is inserted into the mounting opening from one cut end and rotated in the space of the mounting opening. The mounting plate can be placed on the top surface of the ceiling simply by inserting it to the end, and the periphery of the mounting opening of the ceiling can be reinforced with a simple configuration, and the workability is improved.

Also, having thereon a projecting portion on the inner peripheral edge of the opening of the intake with plates, alignment after insertion into ceiling mounting plate, by aligning the mounting opening of the protrusions and the ceiling It can be done easily and the workability is further improved.

Further, to form a pre-Symbol incisions stepwise, which has a structure in which the cut ends overlap together, when fixing the mounting plate with screws to the ceiling, even a screw is threaded into the notches, It will be screwed into the overlapping cut end, and the mounting plate can be securely fixed to the ceiling regardless of the screwing position.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
