Description

[Detailed description of the invention] The present invention relates to an opening/closing panel holding device for a blow-off grill used in a cassette type fan coil unit, etc., and its purpose is to easily open and close the opening/closing panel for inspection, repair, etc. shall be.

Conventionally, in cassette type fan coil units etc. that are mounted on the ceiling, a blowout grille is installed on the ceiling surface, but this blowout grille is provided between the suction side and the blowout side for inspection and operation (valve). An opening/closing panel is provided for this purpose, but conventionally, one side of this opening/closing panel is secured with a hinge, and the other is generally secured with a screw. However, this method of screwing has the drawbacks that it takes time and effort to open and close, that the screws that have been removed can be lost, and that the threads of the screws can become flattened after long-term use.

The present invention is intended to eliminate the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 1 to 5. In Figures 1 to 4, 1 is the main body of the air conditioner which is a cassette type fan coil unit, 2 is the outlet grill which is the lower surface or ceiling surface of the main body 1, and 3 is the suction port provided in the outlet grille 2. , 4 is the air outlet, 5 is the suction port 3, and the air outlet 4.
This is an opening/closing panel installed between the This opening/closing panel 5 is an opening/closing panel provided for inspecting and operating filters, valves, etc. (none of which are shown) inside the main body 1. 6 is the hinge side that serves as a fulcrum, and 7 is the locking side that opens and closes. 8,8'
is the horizontal frame, 9 and 9' are the vertical frames, 10 is the suction grill, 1
Reference numeral 1 denotes a blow-off grill, 12 a hook provided at two places on the opening/closing panel 5, 13 a hook groove cut out toward the end 14 where the hook 12 is provided, and 15 a hook 1.
The folding piece 16 provided with 2 is a hanging device and is shown in detail in FIG. Reference numeral 17 denotes a hook angle having a U-shaped cross section and provided with this hook device 16. In FIG. 4, 18 is the hook angle 17.
Through holes 21 provided in the left piece 19 and the right piece 20,
The sliding shaft inserted in 22, 23 when opening and closing,
24 is the small diameter part where the hook part groove 13 is inserted, 25 is the E-ring A which becomes the stopper, 26 is this E-ring A25.
and a slide portion provided between the right piece 20 and the right piece 20.
7 is an E-ring B provided for controlling the coil spring 28. Spring 28 is E-ring B
27 and the left piece 19 is a compression coil spring that expands and contracts.

In the above configuration, valve operation, filter inspection, etc. are performed by opening and closing the opening/closing panel 5 of the main body 1. At the time of opening and closing, the opening/closing panel 5 is closed as shown in FIG. At this time, since the sliding shaft 18 is biased in the direction of arrow X by the coil spring 28, the hanging portion 12
is the position of the stop 29 of the sliding shaft 18. Therefore, the relationship between the hole of the hanging part 12 and the shaft diameter of the stop part 29 is such that the opening/closing panel 5 is held by being inserted with the hole diameter of the hanging part 12 being slightly enlarged. Next, when opening the opening/closing panel 5, push the push part 23 in the direction opposite to the arrow
5 is pushed in until it hits the right piece 20, and at the same time,
The narrow diameter portion 24 of the sliding shaft 18 slides to the position of the hook portion 12 of the bending piece 15, and the hook portion 12
The opening/closing panel 5 can be opened by passing through the small diameter part 24 through the hanging groove 13 and being removed from the sliding shaft 18. At this time, the E-ring B27 is pushing the coil spring 28 toward the left piece 19 by the amount of the slide, and a force is constantly acting to return it to the right side 20.

Next, after operations, inspections, etc. are completed, the panel 5 can be opened and closed again.
To close the pusher 23, push the pusher 23 toward the right piece 20 by the amount of the slider 26, then insert the hook groove 13 from the narrow diameter section 24 while keeping it pressed, and then press the pusher 23 toward the right side 20. Release part 23. By releasing the coil spring 28, the E-ring B27 is pushed, and the hanging part 12 is inserted into the stop part 29, and the opening/closing panel 5 is held in the closed state. be.

FIG. 5 shows another embodiment, and the numbers shown in FIG. 5 refer to the same numbers as those shown in FIG. 4. That is, in FIG. 5, the portion of the stop portion 29 where the hanging portion 12 is stopped and held is tapered, and the holding portion is held by the tapered stop portion 29. In this embodiment, the coil spring 28 provided between the E-ring B27 and the left piece 19 is always connected to the gap 30, that is, the right piece 20.
Since a pressing force is applied to the side, the tapered stop part 29 and the hook part 12 are in a state where a pressing force is applied on the circular line at one end of the hook part 12, and they are always in close contact with each other. Therefore, the opening/closing panel 5 does not wobble at all.

Further, the opening/closing operation of the opening/closing panel 5 is performed in the same manner as in the embodiment shown in FIG.

Therefore, it exhibits practical effects such as being able to be opened and closed easily as in the embodiment shown in FIG. 4 without being affected by vibrations.

In this way, the present invention provides a sliding shaft in the through hole provided in the hanging part angle, and has a narrow diameter part at one end through which the push part and the hanging part groove on the opening/closing panel side pass, and a stop part where the hanging part is stopped and held. and a slide part 26, and by pushing the push part by the distance of the slide part, the hanging part of the opening/closing panel is removed and pulled out from the narrow diameter part, so the opening/closing operation is easy. It is easy to put on and can be opened and closed with a single touch. In addition, compared to the conventional screw fastening type, there is no need for a screwdriver, there is no fear of losing screws or crushing the screw threads, and there are practical effects such as improved aesthetics.
