Description

The present invention relates to a register used as an air outlet of an air conditioner in a vehicle interior, and particularly to a register in which a barrel having a substantially circular air outlet is rotated freely up, down, left and right in a cylindrical retainer. ..

Conventionally, as a round register having a circular air outlet in a cylindrical frame, a cylindrical barrel is supported in the cylindrical frame so as to be tiltable up, down, left and right around the center of the air outlet. The register is known in Patent Document 1 below.

In this round register, a cylindrical nozzle housing is inserted into the cylindrical housing so as to be tiltable up, down, left and right, a plurality of blade plates are radially arranged in the nozzle housing, and a knob provided in the center is rotated. It is a structure that rotates the blade plate by operating it.

However, in this conventional register, since it is necessary to attach a pad made of felt or non-woven fabric to the inner peripheral surface of the cylindrical housing, the man-hours for assembling including the pad attaching work increase, and the manufacturing cost increases. There was a problem of bulking. In addition, for pads made of felt or non-woven fabric, the operating load varies greatly from product to product due to variations in the pad attachment position and fiber density, and the cushioning properties and thickness of the pads change over time. There was a problem that the nozzle housing was loose and the operating load was easily changed.

On the other hand, in the above-mentioned cited document 2, instead of the above-mentioned pad, a round register having a structure in which a spacer made of a soft resin is attached to an inner peripheral surface of an outer cylindrical case is proposed. This register is an operation in which a cylindrical housing is inserted into a cylindrical case, and a plurality of fins are rotatably arranged radially around a shaft support member arranged in the center of the cylindrical housing and provided in the center. Turn the knob to rotate the radial fins. Further, protrusions are projected from the outer peripheral portion of the cylindrical housing at intervals of about 90 degrees, and these protrusions are brought into contact with the inner side surfaces of the four spacers mounted in the cylindrical case to make the cylindrical housing cylindrical. It is configured to hold in the case so that it can be tilted up, down, left and right.

A recess is provided on the inner peripheral surface of the four spacers attached to the inner peripheral surface of the cylindrical case, and the protrusions on the outer peripheral portion of the cylindrical housing are movably fitted in the recess.

Since this spacer is made of soft resin, the cylindrical housing can be held in the cylindrical case without rattling, but the tips of the protrusions protruding radially around the cylindrical housing are inside the concave groove. Since the cylindrical housing moves while sliding with each other, the range in which the cylindrical housing rotates is limited to the range in which the protrusions move in the recesses provided on the inner side surface of the spacer. Moreover, since the cylindrical housing is supported by the four protrusions, there is a problem that a not a little gap is generated between the outer cylindrical case and the inner cylindrical housing, and air leakage occurs from the gap.

When assembling this register, a spacer is fitted into each recess provided on the inner peripheral surface of the cylindrical case, and in that state, a pre-assembled cylindrical housing having fins and shaft support members is placed in the cylindrical case. insert.

At this time, the cylindrical housing is inserted into the cylindrical case while a plurality of protrusions protruding from the outer peripheral portion of the cylindrical housing are brought into contact with the concave grooves of the plurality of soft spacers. Since it is soft, the position is likely to shift during assembly work, and the spacer located above is likely to fall. For this reason, there is a problem that the assembling work takes time and the assembling workability tends to deteriorate.

An object of the present invention is to solve the above-mentioned problems, and to provide a register which has good assembly workability, can prevent rattling of a barrel, and can reduce air leakage from a gap between a retainer and a barrel. And.

In the present embodiment, the annular gap member 2 is divided into two gap pieces 20A and two gap pieces 20B, and the upper gap piece 20A shown in FIG. 16 and the lower part shown in FIG. 17 are formed. The gap piece 20A is made symmetrically, and the gap piece 20B shown in FIG. 15 is shared by the left part and the right part. The ring gap member 2 can also be formed, and the size, shape, and number of each divided gap piece can be arbitrarily changed.

Further, as described above, the gap pieces 20A and 20B of the annular gap member 2 can be molded using a normal synthetic resin material, but a material having good slipperiness such as a fluororesin or a polyamide resin is desirable. Further, the thermoplastic elastomer can be used to form the gap pieces 20A and 20B, and an appropriate operating load can be applied to the rotation operation of the barrel 1 while preventing rattling.

When assembling the register having the above configuration, first, the barrel inner cylinder 12 is fitted into the barrel outer cylinder 11 of the barrel 1, as shown in FIG.

Further, the bulging portions 21 of the gap pieces 20A and 20B of the annular gap member 2 abut with elastic force on the outer peripheral surface of the barrel outer cylinder 11 of the barrel 1 located inside, and come into contact with the inner peripheral surface of the retainer 3. Since the barrel 1 is assembled, the barrel 1 is elastically supported from the outer peripheral portion in the retainer 3, and rattling of the barrel 1 due to a dimensional error within the tolerance range appearing for each product can be prevented. Furthermore, the barrel can be rotated and operated with a constant operating load without causing rattling for a long period of time.

Further, since ordinary synthetic resin that can be elastically deformed can be used for the gap pieces 20A and 20B, the assembly workability is good, and the register can be manufactured efficiently and at low cost. Further, since the annular gap member 2 is attached in an annular combination between the inner peripheral surface of the retainer 3 and the outer peripheral surface of the barrel 1, the gap between the inner peripheral surface of the retainer 3 and the outer peripheral surface of the barrel 1 is substantially eliminated.
