Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a blow-out mode changing slide device for rotating a vertical louver for adjusting a wind direction in different directions by sliding a slide plate. Is.

(Prior Art) In the above prior art, as shown in FIG. 9, the cam groove 9'of the slide plate 8'has the same width from the top to the bottom, and it projects on the lower surface of the intermediate portion of the swing link 4 '. The pin 10 'provided is adapted to come into contact with and slide on all side edges of the cam groove 9'.
Furthermore, since each pin 10 'that rotates in a different direction for each vertical louver is controlled by the cam groove 9'to change the blowout mode, the sliding resistance between the pin 10' and the cam groove 9'becomes extremely large, and the slide is performed. The plate 8'has a problem in that it is wavy in the vertical direction and is loosened due to wear to hinder smooth operation.

(Problems to be solved by the invention) In the above-mentioned prior art, a simple slide mechanism is used, but each vertical louver is controlled by a cam groove so that each vertical louver individually rotates in different directions in order to change the blowing mode. Therefore, there is a problem in that excessive resistance is applied to the cam groove and the slide plate corrugates in the vertical direction, causing play due to wear and hindering smooth operation.

The present invention aims to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms a pin on a swinging link for individually rotating a vertical louver for adjusting the wind direction, and forms a curved cam groove for regulating the position of the pin. In a blowout mode changing device in which a slide plate having front and rear corresponding to each vertical louver is slidably moved back and forth along the base of the main body, the cam of the slide plate made of wear-resistant resin is used. The width of the both edges of the groove is tapered so that it goes upwards,
It is characterized in that the uppermost edge is an R surface, a minute clearance is provided between the pin and the pin, and a bead is projected in parallel with the guide rail on the upper surface of the slider of the slide plate that fits in the guide groove and that faces the slider. is there.

(Embodiment) 1 is a case of an automobile air conditioner, in which three horizontal louvers 2 are vertically arranged in a front opening, and six vertical louvers 3 are arranged behind the horizontal louvers 2.

Reference numeral 4 denotes a swinging link arranged corresponding to each vertical louver 3, the base of which is a pin 5 which is pivotally attached to the case base 1a, and the tip of which is a pin 6 below the vertical louver 3. Reference numeral 7 is a rotary shaft of the vertical louver 3. 8 is a slide plate, a case base 1a
A cam groove 9 is formed on the lower surface for restricting the rotating direction of each vertical louver 3, and a pin 10 protruding from the lower surface of the intermediate portion of the swing link 4 is inserted therein. Reference numerals 11 and 12 denote guide rails disposed on both sides of the slide plate 8. A crank-shaped bracket 11a is integrally formed on the right guide rail 11 on the outside, and a reinforcing ring 11b is protruded above the bracket 11a. It is fitted into a boss 13 provided on the lower surface of the case base 1a and is fixed integrally with a screw 14. 11c is the guide rail 1
1 With a linear guide groove formed in the front-back direction of the upper surface, a slider 15 protruding from the lower surface of the slide plate 8 is fitted, and a linear bead 16 is projected in the front-back direction of the upper surface facing the slider 15. It is in contact with the lower surface of the case base 1a. The left guide rail 12 has a flat plate shape, and a reinforcing ring 12b is projected outwardly and upwardly. The guide rail 12 is fitted into a boss 18 projecting on the lower surface of the case base 1a and is integrally fixed with a screw 19. Reference numeral 12c is a linear guide groove formed on the upper surface of the guide rail 12 in the front-rear direction.
Is fitted in and is in contact with the lower surface of the case base 1a having a linear bead 21 projecting in the front-back direction of the upper surface of the slider 20. twenty two
Is a motor, and 23 is a pinion for interlocking the drive of the motor 22 and meshes with a rack 24 formed on one side of the slide plate 8.

According to the present invention, in the slide device for changing the blowing mode as described above, the widths of both side edges of the cam groove 9 of the slide plate 8 made of wear-resistant resin are extended upward as shown in FIGS. 7 and 8. Sliding of the slide plate 8 fitted into the guide grooves 11c, 12c with a tapered surface 9a narrowed down, an uppermost edge 9b as an R surface, and a minute clearance of about 0.1 to 0.05 mm provided between the pin 10 and the pin 10. Guide rails 1 with beads 16 and 21 on the opposite upper surfaces of the children 15 and 20
It projects in parallel with 1,12.

Next, the operation will be described. When the motor 22 rotates forward and backward, the slide plate 8 slides back and forth along the guide rails 11 and 12, and the cam grooves 9 rotate the vertical louvers 3 in different predetermined directions to change the blowing mode. Hour slide plate 8
On both sides of each cam groove 9 of the above, a force is partially applied to the right or left by each pin 10, but the pin 10 is the R surface of the uppermost edge of the cam groove 9.
Only 9b is slid in contact with a small gap of about 0.1 to 0.05 mm, the bead formed on the upper surface of the slide plate facing the slider contacts and slides against the case substrate, and the slide plate 8 is resistant. Since the slide plate 8 is formed of a resin having good wear properties and slipperiness, the slide plate 8 slides smoothly without waviness up and down.

(Effect) According to the present invention, a pin is formed on the swing link for individually rotating the vertical louvers for adjusting the wind direction, and a curved cam groove for restricting the position of the pin is provided at the front and rear in correspondence with each vertical louver. In a blowout mode changing device in which the slide plate is slidably moved back and forth along the base of the main body, a slide plate made of wear-resistant resin is provided so that the width of both side edges of the cam groove is increased upward. A tapered surface, the top edge of which is an R surface, and a minute clearance is provided between the pin and a bead protruding parallel to the guide rail on the upper surface of the slider of the slide plate that fits in the guide groove. Therefore, since the vertical louvers rotate in different directions individually to change the blowing mode, it is possible to prevent the slide plate from waving up and down and to smoothly slide the slide plate.
