DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. A is an outlet grill attached to a hot air outlet of an oil hot air heater or the like.
Is a grill main body 1 formed in a horizontally-long rectangular shape, and a plurality (4) rotatably and horizontally fixed to the grill main body 1.
-8 wind direction adjusting blades 2, 2).

The grill main body 1 is formed by pressing a single thin metal plate to integrally form an upper side 1A, a lower side 1B, a left side 1C, a right side 1D, and a back 1E. A plurality of vertical blade pieces 3 are integrally formed in the portion 1E by cutting and raising. Further, fixed pieces 4 and 4 are integrally formed at both left and right ends of the upper side 1A and the lower side 1B, respectively.
The left side 1C and the right side 1D are fixed by spot welding.

As shown in FIG. 1, a plurality of insertion holes 5, 5 and a plurality of notches are formed in the left side portion 1C and the right side portion 1D facing each other along their longitudinal directions (up and down directions). 6 and 6 alternately, and the order is changed from the top so that one insertion hole 5 corresponds to the other notch groove 6 and one notch groove 6 corresponds to the other insertion hole 5. The insertion hole 5 is formed in a round hole, while each of the cutout grooves 6 is formed in a laterally U-shaped groove shape in which the front edge side of the grill main body 1 is opened.

As shown in FIG. 4, the wind direction adjusting blade 2 is formed by bending a single sheet of metal sheet, and the left and right ends of the wind direction adjusting blade 2 are curled into a cylindrical shape. The pivot shaft portions 2A, 2A are integrally formed. As shown in FIG. 1, the wind direction adjusting blade 2 allows the pivot shaft 2A at one end to be inserted into the insertion hole 5 and then engages the pivot shaft 2A at the other end with the cutout groove 6. By joining, the grill main body 1 is provided via the two pivot shaft portions 2A, 2A.
Are fixed to the left side 1C and the right side 1D.

Reference numerals 7 and 7 denote retaining rods disposed outside the left side 1C and the right side 1D.
Is made of a metal wire having elasticity, and the intermediate portion is alternately engaged with the pivot shaft portion 2A of each wind direction adjusting blade 2 protruding outside the left side portion 1C and the right side portion 1D, whereby each The pivot shaft portion 2A of the wind direction adjusting blade 2 is pressed against the inner portion of the notch groove 6 so that the pivot shaft portion 2A of the wind direction adjusting blade 2 does not come off from the notch groove 6, and both end portions of these retaining rods 7, 7 are provided. Are locked to locking portions 8 formed at the upper and lower ends of the left side portion 1C and the right side portion 1D, respectively.

Reference numerals 9 and 9 denote rotation restricting pieces integrally provided on the rear face 1 of the grill main body 1. The rotation restricting pieces 9 and 9 correspond to left and right ends of the wind direction adjusting blade 2. At predetermined intervals, and functions to regulate the rotation angle of the wind direction adjusting blade 2. In addition,
1 and 2, reference numerals 10 and 10 denote horizontally elongated slit-shaped engagement holes provided on the back surface portion 1 of the grill main body 1, and the engagement holes 10 are connected to the edge of a hot air outlet of a hot air heater. By engaging the pawls, the grill main body 1 can be attached to the hot air outlet.

Next, a procedure for assembling the blowout grill A will be described. First, the left side 1C and the right side 1D of the grill main body 1
After inserting one pivot shaft portion 2A of the wind direction adjusting blade 2 into the insertion hole 5 provided in the
Is engaged with the notch groove 6 provided correspondingly. Similarly,
The remaining wind direction adjusting blades 2 are assembled into the grill main body 1, and after the installation of the wind direction adjusting blades 2 is completed, the retaining rods 7, 7 project from the outside of the grill main body 1 to pivot shaft portions of the wind direction adjusting blades 2. The assembly is completed by alternately engaging with 2A and engaging both ends of the retaining rods 7, 7 with the locking portions 8, 8. The blow-out grill A assembled in this manner is incorporated into a hot-air outlet of a hot-air heater using an engagement hole 10 provided in the back portion 1 of the grill main body 1.

According to this embodiment, the insertion holes 5 are formed in both the left side 1C and the right side 1D of the grill main body 1 formed in a horizontally long rectangular shape. After alternately providing the cutout grooves 6 with the leading edge side opened, and inserting the pivot shaft portion 2A at one end of the wind direction adjusting blade 2 into the insertion hole 5,
By engaging the pivot shaft 2A on the other end side with the notch groove 6, the wind direction adjusting blade 2 is axially fixed to the grill main body 1, so that the grill main body 1 is divided into four parts, up, down, left and right, as in the prior art. It is not necessary to assemble the grill main body by connecting a plurality of wind direction adjusting blades to the left and right parts facing each other and then screwing the four parts together, and press one sheet metal sheet. As a result, the upper side 1A, the lower side 1B, and the left side 1
C, the right side portion 1D and the back surface portion 1E can be formed as one component integrally, and the screw can be unnecessary.

For this reason, the structure is simplified, the number of parts and the number of assembling steps can be greatly reduced, and the cost can be reduced. In addition, the dimensional accuracy can be increased by using an integrally molded product, and the quality can be stabilized. The target strength is also increased, and a thin metal plate can be used.

When each of the wind direction adjusting blades 2 and 2 is incorporated into the grill main body 1, one of the pivot shaft portions 2A of the wind direction adjusting blade 2 can be engaged with the cutout groove 6 from the front of the grill main body 1 by dropping. Therefore, the troublesome insertion work of inserting the pivot shaft portion 5A into the insertion hole 5 is reduced by half, and the incorporation of the wind direction adjusting blades 2 into the grill main body 1 can be performed easily and in a short time. In addition, a plurality of vertical blade pieces 3 orthogonal to the wind direction adjusting blades 2, 2 are provided on a back portion 1 E of the grill main body 1.
3 is formed integrally with the grill main body 1 by cutting and raising, so that the blowing guide function can be enhanced without increasing the number of components at all.

Further, in this embodiment, a plurality of insertion holes, 5, 5 and a plurality of notch grooves 6, 6 are formed by the left and right sides 1C, 1D.
Are provided alternately along the longitudinal direction of
Each of the wind direction adjusting blades 2 is made of metal wire
