BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service lid which is attached to a panel of, for example, a ceiling-embedded air conditioner or the like, by using screws, facing upward.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional ceiling-mounted air conditioner to which a service lid is attached.

The service lid 21 is the service lid 2.
1 is fitted in a set screw hole 23 through which a set screw 25 for attaching the downward facing panel 26 of the ceiling-embedded air conditioner is inserted, and a groove 33 formed in a cross section of an opening 29 of the panel 26. The projection 22 is provided.

The panel 26 is covered with a suction grill 27 during operation of the air conditioner. An air filter 28 is fitted in the panel 26. The panel 26 has the service lid 21 on the panel 26.
Is provided with a screw hole 30 into which a setscrew 25 for mounting is mounted. Further, the panel 26 is fixed to the air conditioner main body 35 with a panel fixing screw 31. Inside the opening 29 of the panel 26, an electrical equipment box 32 and switches are provided.

The service lid 21 is the service lid 2.
By fitting the projection 22 of No. 1 into the groove 33 of the opening 29 of the panel 26 and screwing the set screw 25 through which the set screw hole 23 of the service lid 21 is inserted into the screw hole 30 of the panel 26 from below. , Is attached to the panel 26 from the lower side to the upper side.

In addition, the service lid 21 loosens the set screw 25 and sets the set screw 25 into the screw hole 3 of the panel 26.
0 and remove the protrusion 22 of the service lid 21
It is removed from the panel 26 by pulling it out of the groove 33 of the opening 29 of the panel 26.

[0007]

By the way, in order to remove the conventional service lid 21 from the panel 26, the set screw 25 is completely loosened from the screw hole 30 of the panel 26, and the service lid 21 is removed. The set screw 25 supporting the above from below must be removed from the screw hole 30. Therefore, the service lid 2
1 to remove from the panel 26, the set screw 2
When 5 is completely loosened, the set screw 25 and the service lid 21 try to drop downward at the same time, which causes a problem that workability is very poor.

The set screw 25 and the service lid 21 are also provided.
If the worker cannot receive the setscrew 25 and the service lid 21 from the lower side when both and are trying to drop at the same time, the service lid 2 is dropped due to the drop.
1 damage, scratches and scratches on the floor and a set screw 2
Problems such as loss of 5 occur.

Therefore, an object of the present invention is to provide a service lid which can be detached without loosening the mounting screws and has good workability for removal.

[0010]

To achieve the above object, the service lid of the present invention has a diameter larger than the diameter of the shank of the mounting screw and smaller than the diameter of the head of the screw. The shaft part of the screw is slidable while connecting the mounting hole of diameter, the mounting hole of larger diameter than the head part of the screw, and the mounting hole and the mounting hole of the screw. And a connecting hole.

[0011]

When the service lid having the above structure is to be removed from the object to which the service lid is attached, first, the service lid is fitted into the hole for attachment to fix the service lid to the object to be attached. Loosen the screw for a little. Then, the service lid is slid so that the shaft portion of the screw slides up to the removal hole along the connection hole that connects the attachment hole and the removal hole. Then, since the removal hole is larger than the head of the screw, the service lid can be easily removed from the screw and the attachment target. In this way, the service lid can be removed from the object to be mounted without completely loosening the mounting screws. Therefore, especially when removing the service lid screwed from the underside of the mounting object by the mounting screw, both the mounting screw and the service lid can be separated from the mounting object at the same time. Therefore, it is possible to avoid the situation of falling and improve the workability of removal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. FIG. 1A shows a service lid 1 of the present invention and a panel 6 facing downward of a ceiling-embedded air conditioner to which the service lid 1 is attached. The service lid 1 has a set screw 5 for attaching the service lid 1 to the panel 6.
Panel-shaped set screw hole 3 for inserting the
Is provided with a cover portion 2 for covering the panel fixing screws 11 for fixing the above to the air conditioner body (not shown). As shown in FIG. 1 (B), the daruma-shaped set screw hole 3 has a diameter larger than the diameter of the shaft portion of the set screw 5 and smaller than the diameter of the head portion of the set screw 5 for mounting. The hole 3a, the detaching hole 3b having a diameter larger than the diameter of the head of the set screw 5, the attaching hole 3a and the detaching hole 3b are connected, and the shaft portion of the set screw 5 is connected. Comprises a slidable connecting hole 3c.

When removing the service lid 1 from the panel 6, first, the service lid 1 is fitted to the mounting hole 3a and screwed into the screw hole 10 of the panel 6, and the service lid 1 is attached to the panel 6. Slightly loosen the set screw 5 that is fixed. Then, the service lid 1 is slid so that the shaft portion of the set screw 5 slides along the coupling hole 3c to the hole 3b for removal. Then, since the removal hole 3b is larger than the diameter of the head of the set screw 5, the service lid 1 can be easily removed from the set screw 5 and the panel 6. In this way, the service lid 1 can be removed from the panel 6 without completely loosening the set screw 5. Therefore,
When removing the service lid 1 screwed to the panel 6 from the lower side of the panel 6 by the set screw 4, it is possible to avoid a situation in which both the set screw 5 and the service lid 1 drop from the panel 6 at the same time. It becomes easy for the operator to perform the removal work with one hand, and the removal workability can be improved.

[0014]

As is apparent from the above description, the service lid of the present invention has a mounting hole having a diameter smaller than the diameter of the head of the mounting screw and a mounting hole larger than the head of the screw. Since it has a connecting hole that connects the hole for mounting and the hole for mounting, when loosening, loosen the screw a little and move the head of the screw to the position of the hole for detaching. It can be slid and easily removed from the screw. Thus, the service lid of the present invention can be removed from the object to be attached without completely loosening the attachment screw. Therefore, especially when removing the service lid screwed from the underside of the mounting object by the mounting screw, both the mounting screw and the service lid can be separated from the mounting object at the same time. Therefore, it is possible to avoid the situation of falling and improve the workability of removal.
