BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a register for forming an opening for blowing air-conditioning air of an air conditioner of an automobile or the like, and more particularly to a circular register.

[0002]

2. Description of the Related Art An instrument panel of an automobile is provided with a register as an opening for blowing hot and cold air from an air conditioner. As shown in FIG. 6, the register includes a cylindrical retainer 100 that forms an air flow path and a blowing opening, and a plurality of parallel horizontal fins 200 and vertical fins 201 that are swingably arranged in the retainer 100. A variable means such as a knob (not shown) that changes the angle of the horizontal fin 200 and the vertical fin 201 to the retainer to change the air blowing direction, and generally drives the variable means manually to adjust the angle of the fin. By adjusting it, the blowing direction can be adjusted.

For example, one end of each of a plurality of horizontal fins 200 is pivotally supported by a side plate 202, and the other end is connected to a connecting rod 20.
3 and are parallel to each other. Then, the side plate 202 is fixed to the retainer and the connecting rod 20 is fixed.
3 are connected to a link mechanism (not shown), and the link mechanism drives the connecting rod 203 so that all the horizontal fins 20 are connected.

[0006]

However, since the conventional register has a large number of parts as described above, the number of assembly steps and the number of production control steps are large, and the cost is high accordingly. Further, since the air passes between the plurality of fins, the wind noise due to the ventilation resistance is large, and the directivity of the blown air is not sufficient.

The present invention has been made in view of such circumstances, and has as its object to reduce the number of parts in a round register, reduce wind noise, and improve directivity.

[0008]

SUMMARY OF THE INVENTION A feature of the present invention, which solves the above-mentioned problem, is that the round register extends in the diameter direction of the cylindrical substrate constituting the air-conditioning air flow passage and the blow-out opening. A shaft member rotatably pivotally supported on the peripheral surface; a cylindrical member substantially conforming to the inner peripheral shape of the cylindrical base member; and a pivot member pivotally supported on the shaft member in a direction substantially orthogonal to the rotation direction of the shaft member. By rotating the shaft member with respect to the cylindrical base, and by rotating the cylinder member with respect to the shaft member,
The configuration is such that the airflow direction of the air-conditioning air blown from the cylindrical member is adjusted.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In a round register according to the present invention, a cylindrical base is a member to be mounted provided on an instrument panel or the like, and the other can be constituted only by a shaft member and a cylindrical member. By assembling the shaft member and the tubular member in advance, the assembling process requires only pivotal support of both ends of the shaft member to the cylindrical base, so that the number of assembling steps can be significantly reduced. Further, since the number of parts is small, the number of man-hours for production control can be reduced, and the cost can be greatly reduced.

In the round register of the present invention, air conditioning air blows out from the opening of the cylindrical member during air conditioning. By rotating the shaft member with respect to the cylindrical base and rotating the cylinder member with respect to the shaft member, the direction of the air blown from the cylinder member can be adjusted arbitrarily. Therefore, the wind direction can be adjusted without the need for the fin, which is conventionally required, so that wind noise can be reduced. Further, since the wind direction is controlled by the cylindrical member, the directivity of the blown air is also improved.

The cylindrical member may have an integral shape, but it is preferable that the cylindrical member is formed of a pair of half-shaped members so as to form a cylindrical shape. With this configuration, the pivotal support structure with the shaft member can be further simplified, and the number of assembly steps can be further reduced. Further, it is preferable that a circular plate portion substantially corresponding to the cross section of the cylindrical base is formed at the center of the cylindrical member in parallel with the shaft member.
Thereby, the round shape is further emphasized, so that the design is improved. By rotating the shaft member with respect to the cylindrical base to rotate the cylindrical member with respect to the cylindrical base, the axial direction of the plate portion is substantially parallel to the axial direction of the cylindrical base. The opening of the substrate can be closed by the plate,
The stop can be easily switched.

The shaft member may have a straight shape so that both ends can be pivotally supported on the cylindrical base. However, it is preferable that the shaft member further has, for example, an arc portion having a diameter of the straight shaft portion. With this arc portion, the round shape is further emphasized, and when the cylindrical member is formed of a pair of half-shaped members, the arc portion can hide the gap formed between the two. Therefore, the design is improved.

It is preferable that the shaft member and the cylindrical member are connected via an elastic member. Thereby, an appropriate feeling of resistance can be obtained when adjusting the wind direction, and the operation feeling is improved.
Further, a problem that the wind direction angle is shifted due to vibration or the like is also prevented. For the same reason, it is preferable that the shaft member is connected to the cylindrical base via an elastic member. As this elastic member, a leaf spring, rubber, thermoplastic elastomer,
Alternatively, a soft resin such as polyvinyl chloride or foamed urethane can be used.

In the round register of the present invention, the rotation angle of the shaft member and the cylindrical member can be 360 degrees without any limitation. However, the rotation angle is limited by providing a locking projection or the like. Is also good.

2 (FIG. 2 shows that the shaft member 20 still has the holding member 23).
The holding member 23 engages with the rectangular recess 12 formed on the inner peripheral surface of the retainer 1. Therefore, when the shaft member 2 rotates, the shaft portions 20,
The sliding contact 21 with the holding member 23 generates an appropriate resistance due to the frictional force with the holding member 23, so that the operation feeling is improved. In addition, rotation due to vibration or the like is also prevented.

A part of the ring part 22 is provided with a projection 24 protruding in the outer peripheral direction, and the rotation is restricted at a position where the projection 24 is engaged with the step part 13 provided on the inner peripheral surface of the retainer 1. It is configured to: Further, on the inner peripheral surface of the ring portion 22, three convex portions 25 projecting toward the inner peripheral side at a predetermined distance from each other and a notch portion 26 are provided.

The cylindrical member 3 includes a disk portion 30, an arc-shaped bridge portion 31 connecting left and right sides of the disk portion 30, a ridge 32 formed on the surface of the disk portion 30, and a ridge 32. And four ribs 33 connecting the bridge portion 31 and the bridge portion 31. The bridge portion 31 forms a part of a spherical surface and has an outer peripheral surface similar to the surface of the spherical surface 11 of the retainer 1. An uneven portion 34 is formed on the surface of the ridge 32.

As shown in FIG. 3, a cylindrical portion 35 and four locking plates 36 which are spaced apart from each other and project outward from the cylindrical portion 35 are provided on the surface of the disk portion 30. At the eccentric position, a rod member 37 protrudes in parallel with the central axis direction. The cylindrical member 4 also has the same disk portion 4 as the cylindrical member 3.
0, a bridge 41, a ridge 42 (not shown), a rib 43, and an uneven portion 44 (not shown) are formed.

On the surface of the disk portion 40 of the cylindrical member 4,
A ring-shaped engagement ring 45 having a smaller diameter than the disk portion 40 is formed, and the engagement ring 45 is partially formed with a plurality of grooves 46. In addition, a locking projection 47 protruding in the outer peripheral direction is formed on a part of the engagement ring 45. Further, at the center of the disk portion 40, a partially cut-out cylindrical portion 48 is formed upright from the disk portion 40.

In order to assemble the round register of the present embodiment configured as described above, first, the shaft member 2 is placed on the back surface of the disk portion 40 of the cylindrical member 4. At this time, the locking projection 47 is located between the two convex portions 25, and the ring portion 22 is disposed outside the engagement ring 45. In this state, the ends of the three convex portions 25 of the shaft member 2 abut against the outer peripheral surface of the engagement ring 45, and the shaft member 2 is guided by the outer peripheral surface of the engagement ring 45 and is rotatable. . Conversely, the cylindrical member 4 is rotatable along the ring portion 22 of the shaft member 2. However, at the position where the locking projection 47 abuts on the projection 25, the rotation is restricted.

Next, the metal spring 5 is arranged in the notch 26. Due to the elastic force of the spring 5, an appropriate resistance force is generated between the shaft member 2 and the engagement ring 45, so that the operation feeling is improved. In addition, rotation due to vibration or the like is also prevented. Then, the surface of the disk portion 30 of the cylindrical member 3 is adjusted to face the surface of the disk portion 40 of the cylindrical member 4.
At this time, the rod member 37 protruding from the disk portion 30 and the cylindrical portion 4
8 interferes with each other, so that the disk portion 30 and the disk portion 40 can be opposed to each other only in a state where the rod member 37 is engaged with the notch of the cylindrical portion 48. In this state, when the disk portion 30 and the disk portion 40 are rotated so as to twist each other, the engagement plate 36 of the disk portion 30
And the cylindrical member 3 and the cylindrical member 4 are fixed at the position where the ridge 34 and the ridge 35 overlap.

In this state, a gap exists between the disk portion 30 and the disk portion 40, and the shaft member 2 is rotatably disposed in the gap. Therefore, the outer peripheral surfaces of the disk portion 30 and the disk portion 40 and the outer peripheral surface of the ring portion 22 have an integrated circular design. Further, the curvature diameters of the bridge portions 31 and 41 and the diameters of the disk portions 30 and 40 are configured to be the same, so that they have a spherical shape as a whole. Further ridge 3
4 and the ridge 44 have an integral spindle-shaped appearance design, and the bridge portion 31 and the bridge portion 41 have an integral cylindrical appearance design. The ribs 33 and 43 look like continuous radial fins. Therefore, it shows high appearance design.

Finally, the holding members 23 are fitted and held on the shaft portions 20 and 21, respectively. The register ASSY assembled as described above is supplied to the assembly line of the automobile, and the shafts 20 and 21 are retained via the holding member 23 so that the projection 24 of the shaft member 2 is directed toward the back of the retainer 1. 1 opening. Therefore, in the round register of the present embodiment, the shaft member 2 and the cylindrical members 3 and 4 are integrally rotated by rotating about the shaft portions 20 and 21 to rotate vertically along the spherical surface 11 of the retainer 1. When the projection 24 moves, the projection 24 interferes with the step 13 on the inner peripheral surface of the retainer 1, so that the amount of rotation is regulated. That is, the cylindrical members 3 and 4 move up and down within a range of about 180 degrees, and the wind direction can be changed in the vertical direction according to the angle. Also, at the position where the projection 24 interferes with the step 13 on the inner peripheral surface of the retainer 1, the disk portions 30, 40 are almost upright and close the opening of the retainer 1, so that the blowing of the air for air conditioning is stopped. can do. Further, since an appropriate resistance force is generated due to friction between the shaft portions 20, 21 and the holding member 23, the rotation angle does not change due to vibration or the like, and the operation feeling of rotation is excellent.

On the other hand, the cylindrical members 3, 4 integrally engaged and fixed to each other with the ridges 34, 44 are rotated along the ring portion 22 of the shaft member 2 so that the cylindrical members 3, 4 Rotates right and left. Thereby, the wind direction can be changed left and right. However, at the position where the locking projection 47 abuts on the projection 25, the rotation is restricted. Since the elastic force of the spring 5 generates an appropriate resistance between the engagement ring 45 and the shaft member 2, the rotation angle does not change due to vibration or the like, and the rotation operation feeling is also improved. Are better.

Therefore, according to the round register of this embodiment, the bridge portions 31 and 41 of the cylindrical members 3 and 4 and the disc portions 30 and 40
It is possible to freely adjust the wind direction of the air-conditioning air blown from between the vertical direction and the horizontal direction. (Second Embodiment) In the first embodiment, an appropriate resistance force is generated between the shaft member 2 and the cylindrical member 4 by the elasticity of the spring 5. However, in the present embodiment, as shown in FIG.
When arranged on the outer circumference of the engagement ring 45, the projection 25 is pressed in the outer circumference direction and is elastically deformed.

With such a configuration, the shaft member 2
The projection 25 is pressed by the engagement ring 45 by its own elastic force, and an appropriate resistance force can be generated between the shaft member 2 and the cylindrical member 4 without the need for the spring 5. Embodiment 3 In this embodiment, as shown in FIG. 5, a shaft member 6 and a cylindrical member 7 are used. The shaft member 6 has a straight rod shape, and both ends thereof are horizontally supported by the retainer 1 via the holding members 23. In the center of the shaft member 6, an engagement shaft 60 projecting up and down is provided.

On the other hand, the cylindrical member 7 is the cylindrical members 3 and 4 of the first embodiment.
It has substantially the same shape as that of FIG. The disk part 70 has an engaging shaft 60 at the center.
Are provided, and a pair of boss holes 74 are formed at symmetrical positions sandwiching the locking hole 73. The other cylindrical member (not shown) has the same configuration as the cylindrical member 7 except that a boss portion that can be fitted into the boss hole 74 is formed at the position of the boss hole 74.

In the round register of this embodiment, the engagement shaft 60
Are inserted into the engagement holes 73 of the cylindrical member 7 and the other cylindrical member, respectively, so that the shaft member 6 is rotatable along the disk portion 70. Then, the boss portion is fitted into the boss hole 74 to fix the pair of cylindrical members. In this state, since the rotation is restricted at the position where the boss exists, the shaft member 6 can be rotated only at about 180 degrees.

Therefore, the round register of the present embodiment also functions in the same manner as in the first embodiment, and can freely adjust the wind direction. Further, since a gap corresponding to at least the thickness of the shaft member 6 is formed between the disk portions of the pair of cylindrical members, air can be blown through the gap. In the round register of the present embodiment, if an appropriate resistance force is applied to the rotation of the cylindrical member in the left-right direction, an elastic member is disposed on the inner periphery of the engagement hole 73 or the outer periphery of the engagement shaft 60. This can be easily performed.

[0031]

According to the round register of the present invention, the number of parts is extremely small, so that the number of assembling steps can be greatly reduced, and the cost is reduced and the reliability is improved. Further, since a plurality of movable fins as in the related art is not required, wind noise is reduced by reducing resistance, and directivity is also improved because the wind direction is controlled by the cylindrical member.
