Abstract

PURPOSE:To prevent any erroneous assembling operation by a method wherein some louvers are arranged in the same pitch as that of each of grooves, the louvers and a frame acting as a runner are integrally formed through shafts of the louvers and a gate, the shafts of the louvers are fitted in the grooves of a housing while the assembled state being kept and then the gate of the louvers is cut. CONSTITUTION:A plurality of louvers 3 are disposed at the same pitch as a pitch P and formed by synthetic resin through an integral injection molding with a frame 4. The frame 4 also acts as a runner when the injection molding is carried out, and is connected to louvers 3 by a gate 5. When the louvers 3 are assembled in the case 1, the louvers 3 integrally formed with the frame 4 are pushed into grooves 2 of the case 1 with the shafts 3a of the louvers 3 being aligned with them so as to fit the shafts 3a of the louvers 3 into the grooves 2. The gate 5 for connecting the louvers 3 with the frame 4 is broken with a load slightly larger than that required for fitting the shafts 3a of the louvers 3 into the grooves 2. As the shafts 3a of the louvers 3 are pushed into the grooves 2 with a slight higher force, the gate 5 is cut, the frame 4 is separated from the frame 4 and then an assembly of a plurality of louvers can be completed at once.

(Problem to be solved by the invention) However, in this conventional method for assembling the louver in a ventilator, in order to assemble the louver to the housing (for example, a case or a finisher), it is necessary to first mold the louver. Workers had to assemble each louver one by one, which required a large amount of assembly man-hours.Furthermore, the shape of each louver could be different due to the arrangement, which led to problems such as incorrect assembly. Ta.

In view of such problems in the prior art, the present invention improves the workability and reduces the number of assembly steps when assembling a louver to a ventilator housing, and also eliminates the possibility of incorrect assembly of a louver with a different shape. The purpose of the present invention is to provide a method for assembling a ventilator louver without any problems.

(Means for Solving the Problems) In order to achieve the above object, in the ventilator louver assembly method of the present invention, a groove is provided in the ventilator housing into which the shaft portion of the louver is fitted, and the pitch of the groove is the same as that of the groove. A louver is arranged at the pitch, and the louver and a frame that also serves as a runner are integrally molded via the shaft of the louver and the gate, and the shaft of the louver is fitted into the groove of the housing in the integrated state, and the louver is formed. The gate cut is performed.

(Function) In the louver assembly method of the present invention configured as described above, a plurality of louvers to be attached to the housing of the ventilator are arranged in advance at a predetermined pitch to form a frame (runner).
The shaft of the louver is fitted into the groove of the housing in this integrally molded state, and the louver is separated from the frame by making a gate cut. are attached to the housing at once, and the louver can be assembled efficiently without any incorrect assembly.

(Example) The present invention will be described in detail below with reference to FIGS. 1 to 4.

In the ventilator shown in FIG. 1, a plurality of semicircular grooves 2 for fitting louvers are provided at a pitch P on the upper and lower edges of the front end of a case 1 serving as a house sink. On the other hand, a plurality of louvers 3 (embroidered louvers in this example) are arranged at the same pitch as the contacts P, and are integrally formed with the frame 4 by injection molding from a synthetic resin material. The frame 4 also serves as a runner during injection molding, and is connected to the louver 3 by a cage 5.

When assembling the louver 3 to the case 1, attach the frame 4 like this.
While keeping the louver 3 integrally molded in its integral state, align the shaft part 3a of the louver 3 with the groove 2 of the case l, and fit the shaft part 3a of the louver 3 into the groove 2 by pushing it in the direction of arrow A shown in the figure. wear. The gate 5 connecting the louver 3 and the frame 4 is set in a size and shape such that it will break under a load slightly larger than the load required to fit the shaft portion 3a of the louver 3 to 71!2. If the shaft portion 3a of the louver 3 is pushed into the groove 2 and at the same time pushed a little harder, the cage 5 is cut and separated from the frame 4 or the louver 3, completing the assembly of a plurality of louvers at once.

In this case, the frame 4 having the louvers 3 may be placed in correspondence with the case 1, and one louver 3 may be fitted to the beam 2 without cutting its gate 5, or all the louvers 3 may be fitted to the side 2.
After fitting the shaft portions 3a of the gates 3a into the grooves 2, the respective gates 5
The frame 4 may be removed by cutting.

Figures 2 and 3 are enlarged perspective views of the louver mounting portion, and as shown in the figures, the shaft portion 3a of the louver 3 has a flange 3b.
or is formed. The one in Figure 2 is a single flange, and the one in Figure 3 is a tuple flange. Each figure (a>
As shown in FIG.
It is integrally molded so that it is connected to the When assembling to the case 1, in the case of a single flange, the shaft part 3a between the main body 3C of the louver 3 and the flange 3b, and in the case of a double flange, the shaft part 3a between the two flanges 3b.
is fitted to fi2 of case 1, and the gates are further cut (cate cut) to form the state shown in Figure <b>.

Fig. 4 shows the case where the louver is assembled to the finisher 6 as a housing which is attached to the front surface of the ventilator.
will be provided. The louver 8 (horizontal louver in this example) is integrally molded with a frame 9 that also serves as a runner, and is connected by a gate 10.The louver 8 (horizontal louver in this example) is pressed into the finisher 6 in the direction of arrow B in the figure, and the shaft of the louver 8 is The process of inserting the part 8a into the arm 7, applying a load, and cutting the gate 10 is the same as in the case of FIG. 1 above. The finisher 6 in which the louvers 8 are assembled in this way forms a ventilator by being integrated with the front surface of the case 1 in which the louvers 3 shown in FIG. 1 are assembled.

(Effects of the Invention) As explained above, the ventilator louver assembly method of the present invention includes providing a groove in the ventilator housing into which the louver shaft is fitted, and arranging the louver at the same pitch as the groove. Then, the louver and the frame that also serves as a runner are integrally molded via the shaft of the louver and the gate, and the shaft of the louver is fitted into the groove of the housing in the integral state, and the gate of the louver is cut. Because it was made into
A plurality of louvers can be assembled at once, which significantly improves work efficiency and reduces assembly man-hours.

Furthermore, since the plurality of louvers are integrally molded with the frame in advance and assembled, incorrect assembly will not occur even when louvers of different shapes are assembled.
