Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a register of an air conditioner forming an air outlet for ventilation of a vehicle such as an automobile, and more particularly to a spherical member having a spherical register body for adjusting a direction of air blowing. Regarding registers.

2. Description of the Related Art Conventionally, various types of registers for adjusting the direction of air blown from a blower port of a vehicle have been proposed for ventilating a cabin of an automobile or the like. There is a spherical register that can be used. As shown in FIG. 3, the spherical register includes a register case 51 connected to an air vent of an automobile or the like and configured by combining two case bodies 52 and 53, and a spherical inner periphery of the register case 51. A spherical register body 54 is slidably mounted.
An air hole 55 is formed in the register body 54 and communicates with the air outlet through the inside of the register case 51.
5 is divided into a plurality of air outlets 58 by a plurality of fins 57. Each fin 57 is rotatably supported by the register main body 54, and the amount of air blow is adjusted by the amount of rotation of each fin 57.

[0003] In the spherical register, a frictional resistance material 59 such as felt is attached to the entire surface of the spherical inner periphery of the register case 51, and the sliding resistance of the register main body 54 with respect to the register case 51 is controlled by the frictional resistance material 59. Then, the register main body 54 is slid with a desired operating force to adjust the air blowing direction.

[0004]

However, in the conventional spherical register, the sliding resistance of the register main body 54 is managed by attaching a frictional resistance material 59 such as felt to the entire surface of the spherical inner periphery of the register case 51. Therefore, the operation of attaching the frictional resistance material 59 to the spherical inner periphery of the register case 51 is difficult, and the operation takes a long time, resulting in an increase in the manufacturing cost of the spherical register.

[0005] Further, since the frictional resistance material 59 is adhered to the entire surface of the spherical inner periphery of the register case, the amount of use thereof increases, which also causes an increase in the manufacturing cost of the spherical register.

Further, since the sliding resistance of the register main body 54 is controlled by applying a frictional resistance material to the entire surface of the spherical inner periphery of the register case 51, the management area becomes large and the sliding resistance can be easily controlled. There is also a problem that it is difficult to do.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a spherical resistor capable of easily controlling the sliding resistance of the register body while reducing the manufacturing cost.

[0008]

In order to solve the above-mentioned problems, a spherical register according to the present invention is characterized in that a spherical register body is slidably mounted in a two-part register case. In a spherical register for adjusting the blowing direction of air blown into the register case by sliding the main body, the register case has an elongated hole extending in the air blowing direction, and the register main body has Rotate to the register case through the elongated hole,
And a shaft portion supported so as to be freely slidable in the blowing direction, and a shaft portion protruding from the register case is restricted from rotating with respect to the register case, and rotates the register main body with a desired rotational force. The bearing is provided with a bearing that is press-fitted to such an extent that the resistor body can be pressed, and a frictional resistance material that is pressed against the register case by the bearing and that can slide the register main body with a desired sliding force in the blowing direction. This makes it possible to easily manage the sliding resistance generated between each shaft portion and each bearing when the register body rotates, simply by adjusting the press-fitting allowance for each shaft portion of each bearing. , The register body can be rotated by the action of the desired rotational force that overcomes the above. In addition, when the frictional resistance material is pressed by the bearing, the sliding resistance generated between the frictional resistance material and the register case when the register body slides in the air blowing direction can be easily managed. The register body can be slid by the action of a desired sliding force that overcomes the dynamic resistance.

According to a second aspect, in the first aspect,
The bearing has a surface shape that allows the frictional resistance material to follow the outer shape of the register case. Accordingly, when the frictional resistance material is pressed by the bearing, the frictional resistance material closely adheres to the outer shape of the register case, so that the sliding resistance of the register main body in the air blowing direction can be managed with a relatively small management area.

According to a third aspect of the present invention, in the first or second aspect, the register case is provided with two restricting portions extending in the air blowing direction with the long hole interposed therebetween.
Each of the restricting portions is engaged with a bearing press-fitted into the shaft portion to restrict rotation of the bearing with respect to the register case. Thus, the rotation of the bearing with respect to the register case can be regulated with a simple structure.

According to a fourth aspect of the present invention, in the first to third aspects, a shaft protruding from the register case is provided with a frictional resistance material fitted into the shaft and a press-fitted bearing. A circumferential groove into which a split retaining ring pressed toward the case is mounted is formed. Thus, the friction resistance material and the bearing can be fitted to the shaft portion of the register main body, and the split ring can be mounted in the circumferential groove, and the friction resistance material and the bearing can be provided to the bearing by work.

FIG. 1 is an exploded perspective view showing components of the spherical register of the present invention, and FIG. 2 is an assembled state diagram of the spherical register of the present invention.

In FIG. 1 and FIG.
Rotate the register body 2 and the register body 2
It comprises a register case 3 slidably assembled, a frictional resistance member 4 for sliding the rester body 2 at a desired sliding force f, and a bearing 5 for rotating the register body 2 at a desired rotational force f '. ing.

The register body 2 is formed into a spherical shape using a resin material such as ABS, for example, and has a plurality of air outlets 6 penetrating therethrough in parallel with each other.
Each of the air outlets 6 is formed by a plurality of vertical fins 8 and horizontal fins 9 formed at the same time as the molding of the register main body 2 so as to partition an air hole 7 penetrating through the register main body 2. Each air outlet 6 is provided on the outer periphery of the register body 2.
Are formed integrally with each other. The two shaft portions 10 are orthogonal to the extending direction and project from positions spaced from each other by an angle of 180 °. A peripheral groove 12 in which the split retaining ring 11 is mounted is formed in each shaft portion 10.

The register case 3 is formed by combining two case members 15 and 16 formed of a resin material such as ABS, for example.
A stepped hole 19 is formed by the combination of the step 16 and the ventilation hole 17 and the spherical hole 18 along the spherical shape of the register main body 2 penetrating continuously. The ventilation hole 17 of the stepped hole 19 is connected to an air vent of a vehicle (not shown) when the register case 3 is attached to the vehicle or the like. Each case body 15, 16 has a bottom 18 of a spherical hole 18 facing each other by combination.
A long hole 20 is integrally formed in each of the parts a. Each long hole 2
Reference numeral 0 denotes a direction in which air is blown into the register case 3 (in a direction orthogonal to the shaft 10 of the register body 2) and has a diameter such that each shaft 10 of the register main body 2 can rotate and slide. I have. The case body 15 has four protrusions 22 protruding from the division surface 21 with respect to the case body 16, and each protrusion 22 is formed with an engagement hole 22 a. In the case body 16, four projections 23 that fit into the engagement holes 22 a of the respective projections 22 are uniformly formed. In addition, in the vicinity of the long hole 20 of each of the case bodies 15 and 16, a long hole 2
A pair of regulating portions 24, 24 extending in the air blowing direction with 0 interposed therebetween are formed so as to protrude.

The register case 3 thus configured
By sandwiching the divided surfaces 21 of the case bodies 15 and 16 to sandwich the register body 2, the shaft portions 10 of the register body 2 penetrate through the elongated holes 20. Then, the projection 22 of the case body 15 is fitted to the projection 23 of the case body 16 to be combined, and the spherical register main body 2 is integrally assembled and held in the register case 3.
When the register main body 2 is assembled into the register case 3, the elastic tape 30 made of foamed resin or the like is interposed in the spherical hole 18 in the vicinity of the ventilation hole 17 of the stepped hole 19, so that air can be directly transferred to the register. It is prevented from flowing out from the spherical hole 18 of the case 3 to the outside. Thereby, the register main body 2 can rotate with respect to the register case 3 about each shaft 10 as an axis, and by moving each shaft 10 along each long hole 20, the register body 2 swings in the direction in which the stepped hole 19 extends. It is able to move.

The frictional resistance member 4 is made of a rough surface material such as felt or urethane. The frictional resistance member 4 is externally fitted to each shaft portion 10 protruding outside from each of the case bodies 15 and 16 of the register case 3, and The outer surfaces of the bodies 15 and 16 are in contact with each other. The bearing 5 is made of a resin material such as POM by using the outer shape of each of the case bodies 15 and 16 (each of the case bodies 1 between the respective regulation portions).
5 and 16). The sliding holes 5A are press-fitted into the respective shaft portions 10 with a predetermined press-fitting allowance. The press-fitting allowance of the bearing 5 into the shaft portion 10 is such that the register main body 2 can be rotated when a desired rotational force f ′ is applied to the register main body 2. In other words, the register main body 2 is not rotated by the operation of the desired rotational force f 'or less, and the press-fitting margin is set so that the register main body 2 can be positioned at that position. Then, the bearing 5 is connected to each case body 15, 1
6, the frictional resistance member 4 is pressed against the register case 3 so as to follow the outer shape of each of the case bodies 15, 16, and the bearing 5 itself is inserted into each of the restricting portions 24, 24. The rotation with respect to the register case 3 is regulated by engaging with the regulating portions 24, 24. Here, bearing 5
The force that presses the frictional resistance material 4 against the register case 3 by pressing the register body 2 in the air blowing direction is a desired sliding force f.
Is adjusted to a force that can slide. Next, after the frictional resistance material 4 and the bearing 5 are externally fitted and press-fitted into each shaft portion 10, the split ring 11 is mounted in the circumferential groove 12, and the frictional resistance material 4 and the bearing 5 are removed from the shaft portion 10. Stop.

Thus, the adjustment of the press-fitting allowance of each bearing 5 to each shaft 10 of each bearing 5 whose rotation with respect to the register case 3 is restricted by each of the restricting portions 24, 24 is performed.
The outer circumference of each shaft portion 10 and the sliding hole 5A of each bearing 5 when rotating
Can be easily managed, and the register main body 2 can be rotated by the action of a desired rotational force f 'that overcomes the sliding resistance F'.

When the frictional resistance member 4 is pressed by the bearing 5 so as to follow the outer shape of each of the case members 15 and 16, the adhesion between the frictional resistance member 4 and each of the case members 15 and 16 is enhanced. Each case body 15, 16 and friction resistance material 4
The sliding resistance F generated between the frictional resistance member 4 and each of the case bodies 15 and 16 when the register main body 2 slides in the air blowing direction by reducing the contact area (management area) with the register body 2 is reduced. The register body 2 can be easily slid by the action of the desired sliding force f that overcomes the sliding resistance F.

When a desired rotational force f 'is applied to the register main body 2 to rotate the register main body 2, sliding generated between the outer periphery of each shaft portion 10 and the sliding hole of each bearing 5 is performed. Since the register main body 2 is rotated around each shaft portion 10 by overcoming the dynamic resistance F ′ (frictional resistance), the register main body 2 is held at the position after the rotation by releasing the applied rotational force f ′. , Each air outlet 6 of the register body 2
Is changed.

When a desired swinging force f is applied to the register body 2 to swing the register body 2,
The register body 2 overcomes the sliding resistance F (friction resistance) generated between each frictional resistance material 4 and the outer shape of each case body 15, 16, and the register body 2 guides each shaft portion 10 through each long hole 20 while air is guided. The register body 2 is held at the position after the swing by releasing the applied swinging force f, and the direction of each air outlet 6 of the register body 2 is changed.

As described above, by rotating the register main body 2 in the rotational direction and swinging in the air blowing direction to change the direction of each air outlet 6, the air sent from the air blowing port of a car or the like can be obtained. Is blown out from the air holes 17 of the register cover 3 through the air outlets 6 of the register main body 2 in a predetermined air blowing direction, and is used for ventilation of a cabin of an automobile or the like.

Can easily manage the sliding resistance, and the register body can be rotated by the action of a desired rotational force that overcomes the sliding resistance. In addition, when the frictional resistance material is pressed by the bearing, the sliding resistance generated between the frictional resistance material and the register case when the register body slides in the air blowing direction can be easily managed. The register body can be slid by the action of a desired sliding force that overcomes the dynamic resistance. In addition, since the sliding resistance of the register body can be managed by arranging the frictional resistance material and the bearing with respect to a fixed area outside the register case, the frictional resistance material is stuck on the entire spherical inner periphery of the register case as in the related art. It is not necessary, and the amount of the frictional resistance material used can be reduced to reduce the manufacturing cost.
