Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a mounting device for mounting an L-shaped metal fitting provided in an air conditioner to a hanging tool having an upper end fixed to a ceiling beam or the like.

[0002]

[Prior Art]

 FIG. 1 is an external perspective view showing a state in which a ceiling-embedded air conditioner is attached to a ceiling. In (A), 1 is provided with L-shaped metal fittings 3 on both sides, and the L-shaped metal fittings are fixed by a suspending tool 2 and a nut 4 etc. which are installed so that the upper end is fixed to a ceiling beam or the like and is lowered to the back of the ceiling. The ceiling-embedded air conditioner installed on the ceiling. Reference numeral 7 is the ceiling seen from the back of the ceiling with the parts necessary for installing the ceiling-embedded air conditioner removed. Conventionally, in order to install a ceiling-embedded air conditioner, two nuts were used for each of the four suspenders that were installed so as to hang down behind the ceiling. It was fixed by tightening the metal fittings. FIG. 1 (B) shows a conventional example, and 4 is two nuts that sandwich the L-shaped metal fitting with two washers 5 and tighten those washers from above and below. However, in the conventional method, the upper nut is in the shadow of the L-shaped metal fitting and cannot be seen, and because it is in the narrow space behind the ceiling, it is necessary to tighten the upper and lower nuts, especially when tightening the upper nut. Work such as pinching nuts with a spanner is time consuming and difficult, and there was a work problem.

[0003]

[Problems to be solved by the device]

 To install the ceiling-embedded air conditioner, use the specially shaped hole provided in the L-shaped metal fitting, and support the L-shaped metal fitting from below with one nut provided in the suspension tool. It is intended to provide a device for attaching and to be easily attached.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, in an air conditioner mounting device with a nut installed so as to hang down from the ceiling, a hole for inserting the nut attached to the hanging device into an L-shaped metal fitting, A first hole smaller than the outer diameter of the nut through which the suspending tool is inserted is formed continuously in this hole, while a locking part is provided on one side for fitting into the hole of the L-shaped metal fitting. The protruding portion provided is provided with a claw portion for locking the protruding portion on the other side at the end of the L-shaped metal fitting, and a second hole for inserting the suspending tool and a concave portion for inserting the nut are provided at substantially the center. Prepare a fixing member consisting of an elastic member provided, insert the nut attached at a predetermined position of the hanging tool into the hole of the L-shaped metal fitting, and move it to the first hole smaller than the outer diameter of the nut. After that, insert the protruding part of the fixing member into the hole of the L-shaped metal fitting, and attach the tip of the hanging tool to the second hole hole. Attach the L-shaped metal fitting to the hanging tool by inserting the nut and fitting the nut into the recess, locking the locking part to the periphery of the hole, and locking the claw part to the end of the L-shaped metal fitting. I did it.

[0005]

[Action]

 As configured above, insert the hanging tool with the nut installed in place into the lower part of the L-shaped metal fitting through the hole for inserting the nut in the L-shaped metal fitting, and then insert the nut. The air conditioner is suspended by moving the suspending tool to the first hole for supporting the nut provided continuously to the hole. Then, by inserting the protrusion of the fixing member into the hole through which the nut is inserted, the hanging tool returns to its original position, and the L-shaped metal fitting is prevented from falling off the nut of the hanging tool. In addition, by fitting the concave portion of the fixing member to the nut, unnecessary rotation of the nut that determines the mounting position in the height direction is prevented.

【Example】

 Hereinafter, a mounting device for an air conditioner according to the present invention will be described in detail with reference to the drawings. FIG. 2 is an assembly view of essential parts of a mounting device for an air conditioner according to the present invention. Reference numeral 10 is a hole for inserting the nut 4 provided in the L-shaped metal fitting 3 for inserting the portion of the nut 4 of the hanging tool 2 with the nut 4 attached at a predetermined position from the upper side to the lower side. In this figure, the suspending tool 2 with the nut 4 attached is moved to the position of the first hole 11 from the hole 10 through which the nut 4 is inserted, and the nut 4 attached to the suspending tool 2 is moved. Supports the L-shaped metal fitting 3 from below. Numeral 20 is provided on one side with a protrusion 21 having a columnar shape and having a locking portion 27 at the base for fitting into the hole 10 through which the nut 4 provided in the L-shaped metal fitting 3 is inserted, and on the other side, the L-shaped metal fitting 3 is provided. It is a fixing member made of an elastic member such as rubber, which has a claw portion 22 for locking and has a second hole 23 substantially at the center of a flat bottom portion 26. FIG. 3 is a view showing holes provided in the L-shaped metal fitting according to the present invention. Reference numeral 11 is a first hole having a hole diameter intermediate between the outer diameter of the suspending tool 2 and the outer diameter of the nut 4, which is continuous with the hole 10 through which the nut 4 is inserted. FIG. 4 is a sectional view showing an assembled state of a mounting device for an air conditioner according to the present invention. Reference numeral 24 is a hexagonal recess provided in the center of the flat bottom portion 26 of the fixing member 20 so as to be fitted therein to prevent rotation of the hexagon nut 4. The second hole 23 for inserting the hanging tool 2 is provided at the center of the recess 24.

Next, the operation will be described. It is installed so that it can be hung from the back of the ceiling, and in order to obtain a position of a predetermined height, a hanging tool 2 to which a nut 4 is previously attached is passed through a hole 10 through which the nut provided in the L-shaped metal fitting 3 is inserted, Insert the nut 4 under the L-shaped metal fitting 3 so that it appears, press it to the left in this state, and move it to the end of the first hole 11 connected to the hole 10 for inserting the nut. The hanging tool 2 and the nut 4 support the L-shaped metal fitting 3 from below. Then, the hanging tool 2 with the nut 4 attached to the predetermined position returns to the original position so that the L-shaped metal fitting 3 does not drop from the through-nut 4 through the hole 10 through which the nut is inserted. Therefore, the projection 21 of the fixing member 20 is fitted into the hole 10 through which the nut is inserted and locked, and the hexagonal recess 24 is fitted into the nut 4, thereby preventing unnecessary rotation of the nut 4. At this time, the tip portion of the hanging device 2 comes out from the second hole 23 of the flat bottom 26. At the same time, the two locking portions 27 provided in the fixing member 20 sandwich the L-shaped metal fitting 3 to fix the fixing member 20.

[0008]

[Effect of the device]

 By inserting the suspenders with nuts into the holes of the L-shaped metal fittings, the work of tightening the nuts in the back of the ceiling becomes unnecessary, and the ceiling-embedded air conditioner can be easily installed in place. Therefore, the work efficiency of the installation work can be improved.
