  The structures of Documents 1 and 2 above can be used to adjust the air flow in the up, down, left, and right directions by changing the horizontal and vertical louvers by the driving force of a single motor. The user cannot arbitrarily set the adjustment that changes the air flow direction up and down with the horizontal louver and the adjustment that changes the air flow direction with the vertical louver. In other words, with the conventional structure, for example, the wind direction cannot be adjusted independently in the up / down direction and the left / right direction by a push button switching operation. This is not enough. Such a request can be realized by changing the horizontal and vertical louvers by the driving force of the dedicated motors (two motors). However, in that case, for example, the number of motors increases and becomes expensive, and incidental parts and wiring become complicated.

  An object of the present invention is to solve the above-described problems and make it possible to independently adjust a horizontal louver upward and downward and a vertical louver left and right using the driving force of a single motor. It is in.

  The invention of claim 1 is used when the flow direction of the pressure-fed air is varied by a horizontal louver that adjusts in the vertical direction and a vertical louver that adjusts in the left-right direction, and the adjustment member on the side of the horizontal louver; In the wind direction adjusting mechanism provided between the adjustment member on the vertical louver side and the single motor, and capable of transmitting the driving force of the motor to the adjustment members on the horizontal louver and the vertical louver side, the driving of the motor Drive gear means that rotates by force, lateral louver side gear means that provides rotational force to the lateral louver side adjustment member, vertical louver side gear means that imparts rotational force to the vertical louver side adjustment member, and lateral louver side gear means And clutch means for operatively connecting one of the vertical louver side gear means to the drive gear means, upper and lower pushbuttons corresponding to the horizontal louver, and corresponding to the vertical louver. There are a total of four push buttons, left and right push buttons, each push button also serving as a switch for the motor, and one of the vertical push button and the left and right push button is connected to the clutch means. And an input operation means which can be switched. The wind direction adjusting mechanism described above is, for example, that the motor is rotated normally or reversely by the pressed button among the push buttons, and when the pressed button can switch the operation connection of the clutch means, By changing the horizontal louver or vertical louver corresponding to the push button in a corresponding direction with switching, the horizontal louver can be adjusted independently in the upward and downward directions and the vertical louver in the left and right directions, respectively. Is.

The inventions of claims 2 to 4 specify specific examples of each means of claim 1, and the invention of claim 5 specifies application examples.
The second aspect of the present invention provides the clutch means as the clutch that is slid against the urging force in conjunction with the pressing of the push button capable of switching the operation connection among the push buttons, and slides integrally with the shaft. And a pair of intermediate gears always meshed with the corresponding lateral louver side gear means and vertical louver side gear means, and the same gear on the drive gear means side and facing the corresponding intermediate gear, respectively. A pair of bevel gears, one of which is operatively connected to the corresponding bevel gear according to the sliding of the shaft, and the other is not connected.
The third aspect of the present invention provides the clutch means further comprising: a projecting piece incorporated in one of the intermediate gear and the bevel gear and being urged in the projecting direction; It is the structure which has the power coupling means which consists of a possible engaging part.

In claim 4, as the input operation means, four switches provided corresponding to each of the push buttons, and the clutch among the push button for the vertical direction and the push button for the horizontal direction provided at the tip of the shaft. And a contact plate substantially in contact with the push button for switching the operation connection of the means, and when one of the push buttons is pressed, the switch corresponding to the pressed push button is being pressed. Only the motor can be rotated forward or backward.
-Claim 5 is a vertical louver which adjusts the flow direction of the air pressure-fed from the air conditioner to the passenger compartment side in the upward and downward directions, and the vertical direction which adjusts in the left and right directions. A vehicle ventilator that is variable depending on a louver has the wind direction adjusting mechanism according to any one of claims 1 to 4.

  According to the first aspect of the present invention, the operation connection of the lateral louver side gear means and the vertical louver side gear means to the motor side drive gear means is switched by the clutch means, and at the same time, the input operation means is in the upward, downward, left and right directions. Since the operation connection of the clutch means can be switched on one side of the push button corresponding to the horizontal louver and the push button corresponding to the vertical louver, the following operation is enabled. Here, it is assumed that the push button corresponding to the lateral louver switches the operation connection of the clutch means. In this aspect, when one of the upper and lower pushbuttons is pressed, the motor is rotated forward or reverse, and the clutch means is switched, so that the driving force of the motor is driven gear means, clutch means, lateral louver side gear. It is transmitted from the means to the lateral louver side adjusting member to enable the lateral louver to rotate forward or reverse. When one of the left and right pushbuttons is pressed, the motor is rotated forward or backward (without switching the clutch means), and the driving force of the motor is changed from the drive gear means, the clutch means, and the vertical louver side gear means to the vertical louver. The vertical louver is transmitted to the side adjustment member so that the vertical louver can be rotated forward or backward. As a result, the present invention makes it possible to independently change the horizontal louver upward and downward and the vertical louver left and right by pushing the push button using the driving force of a single motor. By arbitrarily adjusting according to the preference, the comfort can be further improved as compared with the conventional product, and the price can be suppressed because the number of motors is not increased, and problems such as wiring complexity do not occur.

In the clutch means according to claim 2, since the switching of the operation connection is made by sliding the shaft against the urging force by the pressing force of the corresponding push button among the push buttons on the input operation means side, for example, a gear or a gear train Compared with the structure that is switched by the meshing method, it is excellent in simplicity and certainty. Further, in the member relationship, for example, a shaft is disposed behind the input operation means between the drive gear means and the lateral / vertical louver side gear means, and each intermediate gear and each bevel gear are arranged around the shaft axis. By arranging the above, the whole can be made compact, or the relationship with the input operation means for switching the operation connection of the clutch can be improved.
In the power coupling means according to claim 3, when the operation connection of the clutch means is switched via the corresponding push button, the connection of the intermediate gear to each bevel gear can be reliably obtained by the engagement between the projecting piece and the engagement portion. Like that. This structure is devised because when the operation of the clutch means is switched by sliding the shaft, the intermediate gear and the bevel gear are brought into contact with and separated from each other.
In the input operation means according to claim 4, the motor can be rotated forward or backward by a total of four switches corresponding to the push buttons. Each switch is turned on by pressing the opposite push button among the push buttons, and when the push is released, the switch returns to the initial OFF state by the urging force. Thus, the return spring member is provided in the switch. However, in this structure, the two push buttons are applied to the contact plate of the shaft, so that the spring member can be omitted and the number of parts can be reduced.
In the vehicle ventilator according to the fifth aspect, the above-described effects can be provided, whereby the user can easily adjust or set the wind direction to a desired direction, which can contribute to improvement of comfort and comfort in the vehicle interior.

   The best mode of the present invention will be described with reference to the drawings. 1 and 2 show a vehicle ventilator incorporating a wind direction adjusting mechanism according to an embodiment of the invention, FIG. 1 is a schematic external view of the ventilator, and FIG. 2 is a block diagram showing the configuration of the main part thereof. 3-8 has shown the principal part of the wind direction adjustment mechanism. In FIGS. 3 and 4, a part of the gear is shown broken away for easy understanding of the member relationship. In the following description, after describing the overall outline, the structure of the main part is clarified by examples.

(Outline) In FIG. 1 and FIG. 2, the ventilator has a housing 1 having a partially opened front and back, and a horizontal louver 3 and a vertical louver 4 in which the housing 1 is supported via a holding frame 2 and the like.

The front side of the housing 1 is composed of a decorative board 1a. The decorative board 1a exposes the holding frame 2 in a large opening provided substantially at the center, and operation knobs 8 and 9 are disposed in small openings provided on the lower side and the left side of the middle of the left and right sides bordering the opening. In addition, four push buttons U, D, L, and R of the input operation means 40 provided on the right side and constituting the wind direction adjusting mechanism 10 are arranged. In this ventilator, the discharge port of the air conditioner is connected to the rear opening of the holding frame 2, and the flow of air fed from the air conditioner to the front opening side of the holding frame 2 is controlled by an operation knob. The direction of the horizontal louver 3 and the vertical louver 4 can be adjusted or set in an arbitrary direction by manual operations 8 and 9 or automatically using the wind direction adjusting mechanism 10.

  Here, the wind direction adjusting mechanism 10 includes a driving gear unit 15 that rotates by the driving force of the motor 7, a horizontal louver side gear unit 20 </ b> A that applies a rotating force to the adjusting member 5, and a vertical louver side gear that supplies a rotating force to the adjusting member 6. The means 20B, the clutch means 30 for operatively connecting one of the gear means 20A and 20B to the drive gear means 15, and switching the operation connection of the clutch means 30 while switching the motor 7 on and off. Input operation means 40. The holding frame 2 may be any frame that supports the horizontal louver 3 in a substantially horizontal arrangement and the vertical louver 4 in a substantially vertical arrangement independently and variably. The horizontal louver 3 and the vertical louver 4 are each composed of a plurality of blades 3a, 4a, but the number of the louvers is set appropriately. The adjustment member 5 is a means for adjusting the angle of the lateral louver 3 upward and downward by receiving rotational force or power from the corresponding gear means 15A (or the operation knob 8). The adjusting member 6 is a means for adjusting the angle of the vertical louver 4 leftward and rightward by receiving rotational force or power from the corresponding gear means 15B (or the operation knob 9). Conventional methods are appropriately applied as necessary to the configurations of the adjusting members 5 and 6. The motor 7 is rotated forward or reversely via a control circuit 43 by four push buttons 41 (U, D, L, R) and switches 42 (SWU, SWD, SWL, SWR) constituting the input operation means 40. . The driving force of the motor 7 is transmitted from the driving gear means 15 to the gear means 20A or the gear means 20B via the clutch means 30. The driving force of the motor 7 transmitted to the gear means 20A functions as a normal or reverse power that moves the adjusting member 5, and allows the lateral louver 3 to be adjusted upward or downward. The driving force of the motor 7 transmitted to the gear means 20B functions as normal or reverse power for moving the adjusting member 6, and makes the vertical louver 4 adjustable in the left or right direction. The operation knobs 8 and 9 are operatively connected to the output shafts 24a and 24b constituting the both gear means 20A and 20B of the wind direction adjusting mechanism 10, and the corresponding adjusting members 5 and 6 are manually moved to move sideways. The direction of the louver 3 and the vertical louver 4 is adjusted. However, the operation knobs 8 and 9 and portions related thereto may be omitted.

  The details of the motor 7 and the wind direction adjusting mechanism 10 are as follows. The main constituent members are arranged on one side of the housing 1, and include a motor holding portion (not shown) provided in the housing 1, a bearing 11 corresponding to the drive gear means 15, and gear means 15 </ b> A and 15 </ b> B. It is supported by a corresponding pair of bearings 12a, 24a, a bearing 13a corresponding to the clutch means 20, a holding piece 13b, and the like (see FIG. 3).

  The motor 7 has a worm 14 attached to the output shaft 7a. The drive gear means 15 includes a worm wheel 16 meshing with the worm 14, a bevel gear 17, a rotating shaft 18, and the like. The rotary shaft 18 is mounted with a worm wheel 16 on the upper side and a bevel gear 17 on the lower side while being supported by the bearing 11. Further, the bevel gear 17 meshes with two bevel gears 19A and 19B that transmit driving force to the clutch means 30 described later.

  The horizontal louver side gear means 20A and the vertical louver side gear means 20B are arranged up and down, and the constituent members thereof are a spur gear 21, a bevel gear 22, a rotating shaft 23, a bevel gear 24, and a spring 25 (hereinafter referred to as the following). This is almost the same in that it is called "friction clutch means". Of these, the bevel gear 24 is always in mesh with the bevel gear 22 and is rotated in synchronization with the bevel gear 22. The bevel gear 24 of the gear means 20A has a shaft 24a mounted at the center, and the shaft 24a transmits power to the adjusting means 5 on the lateral louver 3 side. The bevel gear 24 of the gear means 20B has a shaft 24b mounted at the center, and the shaft 24b transmits power to the adjusting means 6 on the vertical louver 4 side. The bevel gear 22 is attached to the corresponding end side of the rotary shaft 23. That is, the rotating shaft 23 is mounted with the bevel gear 22 on the corresponding end side and supports the spur gear 21 in a state of facing the bevel gear 22. The friction clutch means 25 is provided between the bevel gear 22 and the spur gear 21 and enables the following operation. In other words, the friction clutch means 25 rotates the spur gear 21 side with the frictional force generated between the spur gear 21 and the bevel gear 22 when the spur gear 21 rotates by receiving the driving force of the motor 7. It is possible to transmit to the bevel gear 22 side. On the other hand, when the bevel gear 22 tries to rotate with the force received from the bevel gear 24 side, it receives a load from the spur gear 21 side. When the load is larger than the set friction force, the bevel gear 22 and the spur gear The bevel gear 22 can be rotated together with the bevel gear 24. Such a structure, when the manual operation by the operation knobs 8 and 9 described above is performed at the same time, makes each adjustment means 5 and 6 in FIG. Do not be regulated by 20B.

  The clutch means 30 includes a shaft 31, a pair of intermediate gears (spur gears) 32A and 32B, a pair of bevel gears 19A and 19B provided between the intermediate gears 32A and 32B, an intermediate gear 32A and a bevel gear 19A. And power coupling means 33 provided between the intermediate gear 32B and the bevel gear 19B. Of these, the shaft 31 is supported by a holding member (not shown) so as to be slidable from the front position in FIG. 3 to the rearward position in FIG. 4, and is usually slid to the front position by the rear biasing means 26. Has been. The biasing means 26 includes a pressing shaft 27 supported by the holding piece 13b and the like, and a spring member 28 that biases the pressing shaft 27 forward. A contact plate 29 is attached to the tip of the shaft 31 in a substantially T shape. The abutting plate 29 is formed of the upper and lower push buttons U. Although it becomes long corresponding to D up and down, you may make it long right and left so that it may mention later. Each of the intermediate gears 32 </ b> A and 32 </ b> B has a mounting hole 32 a and is mounted around the shaft of the front and rear portions of the shaft 51 via the mounting hole 32 a and is slid integrally with the shaft 51. The intermediate gear 32A meshes with the spur gear 21 of the gear means 20A, and the intermediate gear 32B meshes with the spur gear 21 of the gear means 20B. Each meshing state is maintained even if the shaft 51 is slid back and forth. The bevel gears 19A and 19B are supported in a state of being fixed by bearings 13a and the like, and meshed with the same bevel gear 17 described above while penetrating the shaft 31 through the center hole so as to be relatively movable.

  As shown in FIGS. 5 to 7, the power coupling means 33 is provided at the opposing portion between the intermediate gear 32 </ b> A and the bevel gear 19 </ b> A when described on the side of the intermediate gear 32 </ b> A and the bevel gear 19 </ b> A. In this example, the engaging portion 39 is provided on the end surface 38 of the intermediate gear 32A, and the projecting piece 36 is incorporated in the end surface of the bevel gear 19A and is urged in the protruding direction by the urging member 37. Yes. The engaging portion 39 is formed by the concave portion with the end surface 38 having a concave and convex shape. A plurality of the concave portions are provided at equal intervals in the circumferential direction. The projecting pieces 36 are arranged in a pair together with the urging member 37 on the small cylindrical portion 34 provided on the corresponding end face of the bevel gear 19A. The protruding piece has a thin tip 36a and a thick base 36b. The small tubular portion 34 has openings 35 formed at two positions displaced by approximately 180 degrees in the periphery, and two through holes 34b are formed on the projecting end surface corresponding to the openings 35. When each projecting piece 36 is accommodated together with the urging member 37 in the corresponding arrangement portion in the small cylindrical portion 34 from the opening 35, it is pushed forward by the urging force of the urging member 37 and the tip 36a is passed through the through hole. Projecting outward from 34b. Therefore, when each projecting piece 36 is pushed from the tip 36 a, it is retracted into the small tube portion 34 against the urging force of the urging member 37. Reference numeral 35 a denotes a depression for the urging member in the small cylindrical portion 34.

  In the power coupling means 33 described above, when the bevel gear 19A is rotated with the tip of the projecting piece 36 entering the concave shape of the engaging portion 39, the intermediate gear 32A is reliably rotated integrally with the bevel gear 19A. The That is, when the intermediate gear 32A or 32B approaches the corresponding bevel gear 19A or 19B by the longitudinal movement of the shaft 31, the projecting piece 36 hits the end face 38 as shown in FIG. 6, and the intermediate gear 32A or 32B After approaching the corresponding bevel gear 19 </ b> A or 19 </ b> B while retracting, when the protruding piece 36 coincides with the engaging portion 39 as shown in FIG. 7, the protruding portion 36 protrudes into the concave shape of the engaging portion 39. In this way, the power coupling means 33 is devised so that the clutch means 30 switches the operation connection with the longitudinal movement of the shaft 31 so that the corresponding gears can be connected and disconnected satisfactorily.

  The input operation means 40 includes four push buttons 41 (U, D, L, R) arranged on the decorative plate 1a and four switches 42 (SWU, D) arranged corresponding to the back side of each push button 41. SWD, SWL, SWR) and a control circuit 43. The push button U and the switch SWU, the push button D and the switch SWD, the push button L and the switch SWL, and the push button R and the switch SWR are paired. Each push button 41 has a lacking portion 41a provided on the inner side and a restricting piece 41b protruding at the tip, as shown in FIG. Yes. Each push button 41 is pressed and held in the corresponding small opening 1b of the decorative plate 1a, and the restricting piece 41b is moved to the small opening 1b while the base end side is pivotally supported by the decorative frame 1a via the pivot 46. An operating position (switch 42 is rotated to the inside of the decorative board 1a when pressed from the normal position (position where the switch 42 is turned off) applied to the provided step 1d (the position where the switch 42 is turned off) in the direction of the arrow in FIG. To the ON position).

  In this structure, among the push buttons 41, the push buttons L and R are provided independently of the clutch means 30 and have a spring 45 supported by the pivot 46, and the normal force is applied by the spring 61. The position is maintained, and when it is pushed from the outside, it is rotated to the operating position against the urging force. When the pushing force is released, the push buttons L and R are returned to the normal position by the urging force of the spring 45. On the other hand, the push buttons U and D are in a state in which the abutting plate 29 of the shaft 31 is substantially in contact with the back side, and are kept in the normal position by the corresponding contacting plate 29, and when pressed from the outside, At the same time, the abutting plate 29 is pushed backward, the shaft 31 is slid in the same direction, and the operation connection of the clutch means 30 is switched. When the pressing force is released, the push buttons U and D return to the normal position by the force when the shaft 31 is slid to the original position by the urging force of the urging means 26. For example, the contact plate 29 of the shaft 31 may be turned 90 degrees to cooperate with the push buttons L and R.

  When the corresponding push button 41 is pressed, each switch 42 abuts the movable terminal 42 a against the fixed terminal 42 b and rotates the motor 7 forward or reverse via the control circuit 43. Of the switches 42, the switches SWU and SWD are provided so as not to buffer the contact plate 29 as shown in FIG. Each movable terminal 42a may be provided integrally with a corresponding push button. Each fixed terminal 42b is connected to a control circuit 43 that controls the motor 7 of FIG. The control circuit 43 is connected to the power source 44 and controls energization to the motor 7 in accordance with the switch 42 that has been selected and operated. In this example, when the push button U or the push button L is depressed, the switch SWU or SWL is turned on only while the push button U is depressed, and the motor 7 is normally rotated by the control of the control circuit 43 during this time. When the push button D or the push button R is pressed, the switch SWD or SWR is turned on only while the push button D is pressed. During this time, the motor 7 is reversed by the control of the control circuit 43. Of course, the rotation direction of the motor 18 corresponding to the switches SWU, SWD, SWL, SWR may be a combination opposite to the above.

Next, the operation of the wind direction adjusting mechanism 10 will be described.
(A) When the push button U in FIG. 3 is pressed, the contact plate 29 is pushed by the push button U. Then, the shaft 31 is slid rearward against the urging force of the urging means 26 as shown in FIG. As a result, the clutch means 30 is connected to the drive gear means 15 and the longitudinal louver side gear means 20B from the connection of the drive gear means 15 and the lateral louver side gear means 20A with the operation of the power coupling means 33 described above. Switch to. At the same time, the switch SWU corresponding to the push button U is turned on. Then, the motor 7 is rotated forward under the control of the control circuit 43. The driving force (rotation) of the motor 7 is transmitted from the worm 14 to the worm wheel 16, the bevel gear 17, the bevel gear 19 B, the intermediate gear 32 B, the spur gear 21, the friction clutch means 25, and the bevel gear 24. The power is transmitted to the adjusting means 5 on the side of the lateral louver 3 in FIG. In this structure, the pressing force of the push button U is released when the lateral louver 3 is adjusted to a target angle. Then, the shaft 31 is slid to the initial state of FIG. 3 by the urging force of the urging means 26. The push button U is pushed by the shaft 31 and returned to the normal position in FIG. 3, the switch SWU is turned off, and the motor 7 is stopped via the control circuit 43. The lateral louver 3 is maintained at an adjusted angle.

(A) When the push button D shown in FIG. 3 is pressed, the clutch means 30 is switched to the connected state between the drive gear means 15 and the vertical louver side gear means 20B as in the case of the push button U described above. At the same time, the switch SWD corresponding to the push button D is turned on, and the motor 7 is reversed via the control circuit 43. The driving force (rotation) of the motor 7 is transmitted from the worm 14 to the worm wheel 16, the bevel gear 17, the bevel gear 19 B, the intermediate gear 32 B, the spur gear 21, the friction clutch means 25, and the bevel gear 24. The power is transmitted to the adjusting means 5 on the side of the lateral louver 3 through the shaft 24b, thereby changing the lateral louver 3 downward. The pressing force of the push button D is released when the lateral louver 3 is adjusted to a target angle. Then, the shaft 31 is slid to the initial state of FIG. 3 by the urging force of the urging means 26, the push button D is pushed by the shaft 31 and returned to the normal position, the switch SWD is turned off, and the motor 7 is controlled. It is stopped via the circuit 43.

(C) In this structure, as can be seen from the above, the clutch means 30 is in the initial state of FIG. 3 when none of the full push buttons 41 is pressed. Therefore, when the push button L in FIG. 1 is pressed, the switch SWL corresponding to the push button L is turned on. Then, the motor 7 is rotated forward under the control of the control circuit 43. The driving force (rotation) of the motor 7 is transmitted from the worm 14 to the worm wheel 16, the bevel gear 17, the bevel gear 19 A, the intermediate gear 32 A, the spur gear 21, the friction clutch means 25, and the bevel gear 24. Power is transmitted to the adjusting means 6 on the side of the vertical louver 4 in FIG. 2 through the shaft 24a to vary the vertical louver 4 in the left direction. The pressing force of the push button L is released when the vertical louver 4 is adjusted to a target angle.
