[Prior Art]

 Conventionally, it has been important to improve the temperature environment inside the vehicle compartment. For example, there is a structure in which wind cooled by an air conditioner is supplied from the upper vent into the passenger compartment in order to promote cold head heat. A movable fin for adjusting the wind direction is provided in such a vent, and an occupant can adjust the wind direction by moving the movable fin.

The above-mentioned movable fins include a plurality of horizontal fins that extend in the left-right direction to adjust the wind up and down, and are rotatable in conjunction with each other, and a vertical fin that adjusts the wind to the left and right. There are a plurality of vertical fins that extend in the direction and can rotate left and right in conjunction with each other, and these are arranged in front and rear of the vent.

In order to adjust the wind direction with such a structure, for example, a knob is attached to a horizontal fin provided on the front side so as to be movable in its extending direction with a through hole, and the knob is provided. Part of the vertical fin is engaged with a vertical fin arranged on the rear side, and the vertical direction of the horizontal fin is changed by moving the knob member up and down, and the vertical fin engaged with this is moved by moving the knob member left and right. The left and right directions of are changed.

Here, in order to prevent rattling from occurring between the picking member and the horizontal fins that support the picking member, conventionally, the picking member is provided with a through hole in either the front-back direction or the vertical direction. A pair of leaf springs urging either one of them or a deforming spring consisting of a single plate material formed by connecting the pair of springs is interposed between the picking member and the horizontal fin, and the front and rear direction thereof and The vertical urging force was adjusted.

However, when the above-mentioned pair of springs is used in a relatively narrow gap, there is a problem that the number of parts increases, the cost rises, and the assembling work becomes complicated. Further, when one deformable spring is used, the spring has a complicated shape, so that the manufacturing cost thereof rises, and the adjustment of the biasing force tends to be troublesome.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 show a blowout structure of a vehicle air conditioner to which the present invention is applied. The vent member 1 provided on the instrument panel in the front of the passenger compartment has left and right lower air outlets 2 and 3 for supplying air from the air conditioner to passengers in the driver's seat and passenger seat, and these vent members 1. Upper outlets 4 and 5 arranged above the lower outlets 2 and 3 are provided (Fig. 1). As shown in FIG. 2, a partition wall 6 separates the upper outlets 4 and 5 from the lower outlets 2 and 3. Each of the outlets 2 to 5 is connected to a duct 7 that communicates with an air conditioner (not shown). Since the outlets 2 and 4 and the outlets 3 and 5 have the same symmetrical structure, only the outlets 2 and 4 on the driver side will be described in detail below. A description of the third and fifth sides will be omitted.

The lower outlet 2 is provided with a plurality of horizontal fins 8 each extending in the left-right direction and rotatable up and down. The horizontal fins 8 are interlocked with each other by a link 10 shown in FIG. 3 and are rotatable in parallel with each other. Further, as also shown in FIG. 5, on the upstream side of the horizontal fin 8 in the duct 7, a plurality of vertical fins 11 extending in the vertical direction and rotatable left and right are provided. .. The vertical fins 11 are interlocked with each other by a link 12 shown in FIG. 5, and are rotatable in parallel with each other.

As shown in FIGS. 2 and 5, a knob member 13 is provided at an intermediate portion of the second horizontal fin 8a from the bottom. The knob member 13 has a hollow cylindrical shape, and the horizontal fin 8a penetrates through the through hole 13a. That is, the picking member 13 is movable in the left-right direction by using the horizontal fin 8a as a guide. Further, a bifurcated engaging piece 14 is projectingly provided on the knob member 13 and engages with the vertical fin 11a at the center. Therefore, when the knob member 13 is vertically rotated, each horizontal fin is interlocked and vertically rotated to adjust the wind direction in the vertical direction, and when the knob member 13 is moved in the horizontal direction, the engaging piece 14 is moved. The vertical fins 11a are driven via the vertical fins 11 and the vertical fins 11 are interlocked to rotate left and right so that the wind direction can be adjusted left and right.

As shown in FIGS. 5 and 6, in the through hole 13a of the knob member 13, a leaf spring 15 is interposed between the inner wall 13b and the horizontal fin 8a. 8a is biased backwards. Further, an engaging piece 16 is projectingly provided on the upper surface 13c of the through hole 13a of the knob member 13 and engages with the engaging hole 8b formed in the horizontal fin 8a. Here, the contact surface between the engagement piece 16 and the engagement hole 8b is an inclined surface that is inclined forward and backward, and the biasing force of the leaf spring 15 also acts in the vertical direction, that is, the picking member 13 is rearward and upward. Is urged towards. Therefore, when the knob member 13 is rotated or moved, it can be operated smoothly without causing rattling.

On the other hand, an opening / closing valve 18 is provided on the upstream side of the vertical fin 11 in the duct 7. The on-off valve 18 is rotated between a substantially vertical fully closed position (imaginary line A in FIG. 2) and a substantially horizontal fully opened position (imaginary line B in FIG. 2) about a pivot 19 extending in the left-right direction. It consists of a moving butterfly valve and gradually leans forward from the fully closed position to the fully open position, but in the duct 7 most of the wind is concentratedly supplied to the upper outlet 4 at an intermediate position ( The imaginary line C) in Fig. 2 can be taken. Here, the valve body 18a of the on-off valve 18 is spaced slightly forward from the pivot shaft 19. Therefore, when the opening / closing valve 18 is in the intermediate position, the opening area on the upper side is larger than the opening area on the lower side.

As shown in FIG. 4, a dial 22 exposed on the surface of the vent member 1 is connected to the pivot 19 via links 20 and 21, and the opening / closing valve 18 is rotated by rotating the dial 22. The opening position of can be adjusted.

When the dial 22 is actually turned to set the open / close valve 18 to the fully closed position (imaginary line A in FIG. 2), no wind is supplied from any of the outlets, and the fully open position (imaginary in FIG. 2). In the line B), the wind is supplied from both the lower outlet 2 and the upper outlet 4, that is, the wind is supplied in a desired direction depending on the direction of the passenger's head and the fins 8 and 11. It Further, when the open / close valve 18 is set to the intermediate position (imaginary line C in FIG. 2), the wind is supplied from almost only the upper outlet 4 toward the passenger's head. Here, a part of the partition wall 6 on the upper air outlet 4 side forms a baffle plate 6a. Therefore, a turbulent flow is generated in the air blown out from the upper air outlet 4, so that there is no discomfort that the wind locally hits the passenger's head.
