Abstract

PURPOSE:To facilitate to keep the angle of a lateral vane by a method wherein a central bearing structure is combined with ratchet pawls in case the lateral vane is long in the lengthwise direction thereof and is to be divided at the center thereof. CONSTITUTION:Divided lateral vanes 3 are inserted into the lateral vane inserting section 16 of a connecting member 5 to integrate them. A holding member 6 is inserted into the gap 18 of the connecting member, an U-groove 9 is abutted against a shaft 15 and the holding member 6 is forced into the long hole notch 12 of a bearing member 11. The stopper 7 of the holding member 6 is fitted into a square hole 13 for the stopper. The U-groove 9 and the long notch 12 constitute a circular section after assembling and become the bearing section of the shaft 15. The ratchet pawls 8 of the holding member 6 and protected and recessed section 14, formed on the circumference of a semi-circular section 17 for the connecting member 5, are arranged concentrically with the bearing section while the tip ends of the ratchet pawls 8, provided with the property of a spring, are pinched slightly by the recesses of the protruded and recessed section 14. Accordingly, the integrated lateral vanes 3 may be held in any arbitrary angle within an angle alpha deg. in accordance with the number of pitches of the protruded and recessed section 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air outlet structure of an air conditioner, and relates to a method of connecting horizontal blades in the longitudinal direction.

[Background of the invention]

As described in conventional Japanese Utility Model No. 54-158474, the wind direction angle was controlled by the recesses of the base frame at both ends and the sliding pieces at both ends of the wind direction change blade, but the blade was long in the longitudinal direction. case,
There were drawbacks such as bending and twisting in the center, and no consideration was given to long blades.

Generally, the rotation of the horizontal blade is controlled by using the elasticity of rubber or by using piano wire, but
When using rubber for the divided parts, there were problems with temperature and deterioration, and when using piano wire, there were problems with the appearance of the assembly.

[Purpose of the invention]

The present invention was invented in view of the above-mentioned problems, and it is an object of the present invention to provide an air outlet structure that does not bend even in long horizontal blades and is easy to rotate.

[Summary of the invention]

In order to achieve the above object, the present invention has an air outlet structure in which when the horizontal blades are long in the longitudinal direction VC, the center part is bent and the appearance is unsightly, and the problem is as follows.
In this bearing structure, it is difficult to maintain the angle of the horizontal blades, and this problem is solved by the combination of ratchet and ratchet pawls.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. FIG. 1 shows how the air outlet 2 and horizontal blades 3 of a conventional air conditioner 1 are attached.

FIG. 2 shows an air outlet 2, a horizontal blade 3, and a bearing member 1 according to the present invention.
1 shows the installation condition. FIG. 3 shows a catching blade 3 that is integral in the longitudinal direction. 4 to 9 show a transverse blade support device according to the present invention.

FIG. 4 shows a combined state of the divided horizontal blades 3 and the connecting member 5, which have shafts 4 at both ends.

FIG. 5 shows the holding member 6, the stopper 7, the U half +49
, a ratchet pawl 8, and a design surface 10. FIG. 6 shows a bearing member 11, in which an elongated hole notch 12 and a square hole 14 for a stopper are provided on both end faces of an opening having a U-shaped cross section.

FIG. 7 shows the continuous FM member 5, which includes a semicircular portion 17, a concave and convex portion 14 formed on the circumference of the semicircular portion 17, and an insertion portion 1.
6 at both ends.

FIG. 8 shows the assembled state, in which the horizontal blade 3 and the holding member 5 are
It is supported by the bearing member 11 and fixed by the holding member 6. FIG. 9 shows a plan assembly cross-sectional view. The operation in the above configuration will be explained.

If the longitudinal dimension of the horizontal blade 3 at the air conditioner outlet is long, the center part will bend as shown by the dotted line in Figure 3, making it unsightly.
This is even more necessary in the case of design-oriented lateral blades that are narrow and have a thin cross section.

The necessary function of the horizontal blade VC is to adjust the wind direction, and it must be held at a certain arbitrary angle.

The divided horizontal blades 3 and the horizontal blade insertion portion 16 of the connecting member 5
It is inserted into the body and made into one piece as shown in Fig. 4. After inserting the holding member 6 into the gap 18 of the connecting member, ill I 5
Apply the U-shaped groove 9 to the elongated hole notch 12 of the bearing member 11.
Slide it in and push it in.

At this time, the stoppers 7 molded at the four corners of the holding part 687)
It is attached to the square hole 13 for the stopper with a snap.

(When attaching and detaching, shrink the stopper 7 inward and remove it from the square hole.) Figure g8 shows the assembled state.
When the groove 9 and the elongated hole notch 12 of the bearing member 11 are assembled, it forms a circular part, becomes a bearing part for the shaft 15 of the connecting member 5, is rotatable at an angle α0, and is held concentrically with the bearing part. Ratchet pawl 8 of member 6 and semicircular portion 170 of connecting member 5
A concave and convex portion 14 formed on the circumference is arranged, and in accordance with this relationship, the tip of the ratchet pawl 8 (or triangular or rounded at the tip) is placed in the concave portion of the concave and convex portion 14.
It is lightly clamped, and when rotated, the latch and lock pawls are given spring properties so that the convex part fits into the next concave part with a sense of resistance. [Effects of the Invention] The above structure Therefore, the integrated horizontal blade 3 has an angle byα0
It is possible to hold any angle as many as the inner purple, 14 unevennesses, and dots, and the resistance due to wind pressure is not affected by the ratchet pawl. In addition, the material is suitable for indexability because heat-resistant and flexible materials can be freely combined. Six time keeping members are provided with a design surface 10, and the design is taken into consideration.

Since the holding member 6 is one-to-one with the horizontal blade 3, the number can be increased or decreased.
There are C degrees of freedom and standardization is achieved.

Assembly can be done from the front down the valley, and the assembly is done by fitting, so the cost is low.
