  2. Description of the Related Art Conventionally, as a round register having a cylindrical air outlet, for example, a register having a round rotation louver that can rotate around a central axis along the air blowing direction of the air outlet is disclosed in Patent Document 1 below. Is known by.

JP 2004-249936 A

  This register includes a retainer and a bezel formed in a cylindrical shape, and a substantially cylindrical rotation louver is rotatably disposed inside the bezel and the retainer. The rotating louver is formed by pivotally supporting one or more movable fins on the inner side of the cylindrical frame so as to be rotatable about an axis parallel to the front surface of the cylindrical frame, that is, an axis perpendicular to the blowing direction. The inner side of the bezel and the retainer is rotatably fitted.

  The bezel is molded into a ring shape with a synthetic resin, and the bezel is fitted to the front part of the retainer by engaging the locking pieces on the bezel side with the locking claws. The stop piece has a locking portion for locking the locking claw formed therein as a rectangular opening hole.

  By the way, since the bezel forms the design part of the register, the bezel made of synthetic resin may be plated. However, when the bezel having the structure as described above is plated, there is a problem for the following reasons. Cracks tend to occur on the piece.

  That is, as shown in FIG. 9, the ring-shaped bezel 51 has a locking portion 52 formed in a ring shape with an inner rectangular opening hole 53 as a locking portion for locking the locking claw on the retainer side. Yes. For this reason, when the bezel 51 is formed by injection molding of synthetic resin, the material flows in the cavity so as to go around the annular portion from both sides of the rectangular opening hole 53 of the locking piece 52. At this time, the material flow in the two directions is incompletely fused at the location where the flow heads merge, and a streak-like weld line is likely to occur at such a portion of the locking piece 52. .

  The weld line is a portion where poor strength is likely to occur. In particular, when the bezel 51 is plated, when the locking piece 52 is covered with the plating film, the weld has a poor strength due to the contraction force of the plating film. Concentrate on the line. For this reason, a weld line is generated in the locking piece 52 of the bezel, and when the locking piece 52 of the bezel 51 is locked to the locking claw on the retainer side in a plated state, the locking piece 52 is cracked. Is likely to occur.

  For this reason, when plating the bezel 51 in the register manufacturing process, as shown in FIG. 10, a plating resist solution is applied in advance to the locking pieces 52 of the bezel 51 to form the plating resist film R. In addition, the plating process is performed so that the latching piece 52 is not plated. However, the step of applying the plating resist solution is an operation in which the operator manually applies the plating resist solution, which requires a large number of work steps and time, resulting in an increase in manufacturing cost.

  An object of the present invention is to solve the above-described problems, and to provide a register that can simplify the manufacturing process and can prevent cracks that are likely to occur in the locking pieces of the plated bezel. And

  In order to achieve the above object, the register of the present invention is a register in which a synthetic resin bezel is fitted to the front part of the retainer, and the bezel is plated. The bezel is provided with a plurality of locking pieces to be locked to the locking claws, and the locking pieces are substantially L-shaped and non-annular.

  According to this invention, since the locking piece is formed in a substantially L shape and a non-annular shape, when the bezel is formed by injection molding of synthetic resin, the material enters the cavity so that the material wraps around the annular portion from both sides of the locking piece. The phenomenon of flowing through does not occur. For this reason, the weld line caused by the poor fusion of the material generated at the part where the flow heads of the materials flowing in the two directions join together does not occur in the locking piece part, and even when the bezel is plated, the strength The defective part does not occur. Therefore, when plating the bezel, there is no need to apply the plating resist solution to the locking piece, and the plating resist solution application process can be eliminated, reducing the number of work steps and time, and reducing the manufacturing cost. can do. Further, since the substantially L-shaped locking piece is easily bent and is easily bent and locked at the time of locking, the locking piece can be prevented from cracking.

  Here, the locking pieces of the register bezel are formed of a pair of L-shaped locking pieces opposed to each other, and can be configured to be locked from both sides of the locking claws. According to this register, the pair of locking pieces can be locked from both sides of the locking claw of the retainer, and the bezel can be firmly fitted to the retainer.

  Further, the retainer is formed in a cylindrical shape, while the bezel is formed in a ring shape and is fitted to the front portion of the retainer, and a rotating louver is rotatably disposed inside the bezel and the retainer. The rotating louver pivotally supports one or more movable fins inside the cylindrical frame so as to be rotatable about an axis parallel to the front surface of the cylindrical frame, that is, an axis perpendicular to the air blowing direction. A frame is rotatably fitted inside the bezel and the retainer, the locking claw is projected on the front outer periphery of the retainer, and the locking piece is located on the back side of the ring-shaped bezel. It can be set as the structure provided so that it may protrude.

  According to the register of the present invention, the manufacturing process can be simplified, and cracks that are likely to occur in the latching pieces of the plated bezel can be prevented.

It is a perspective view of the conventional bezel. It is an expansion partial perspective view of the conventional bezel.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a round register provided in a passenger compartment of an automobile, and FIG. 4 is an exploded perspective view of the register. In general, this register has a cylindrical rotating louver 2 mounted in a cylindrical retainer 1 so as to be rotatable around an axis parallel to the air blowing direction. The first movable fin 21 and the second movable fin 22 are pivotally supported in the air outlet 5 so as to be pivotable about an axis perpendicular to the central rotational shaft 6 of the rotational louver 2, and when fully closed, The adjacent first movable fin 21 and second movable fin 22 rotate to a state where the blowout port 5 is shielded while forming the overlapping portion 213 (FIG. 5) that overlaps each other, thereby closing the blowout port 5. Configured as follows. A ring-shaped bezel 3 is fitted to the front portion of the retainer 1, and the bezel 3 is plated in consideration of the appearance of the front of the register.

  As shown in FIG. 4, the front part of the cylindrical retainer 1 is formed so as to be opened as a whole, and the rear cylindrical part 12 at the rear part is provided with a honeycomb-shaped mesh part 4 for preventing small objects from falling. It is provided so as to cover. The front cylindrical portion of the retainer 1 is formed with a larger diameter than the rear cylindrical portion 12, and as shown in FIG. 5, the cylindrical frame 20 of the rotating louver 2 is rotatably inserted therein. It has become.

  Further, an operation load applying portion 9 is formed at a step portion at the boundary between the front cylindrical portion and the rear cylindrical portion 12 of the retainer 1. The operation load applying unit 9 is formed by continuously arranging a large number of tooth shapes on the circumference, and an elastic leg member 26 (described later) attached to the cylindrical frame 20 has elasticity to the operation load applying unit 9. Accordingly, when the rotating louver 2 is operated, an appropriate operation load is applied, and the rotating louver 2 can be rotated and stopped with a sense of moderation.

  As shown in FIGS. 1 to 3, the locking claws 11 are provided at three positions on the front outer peripheral surface of the retainer 1 so as to lock the locking pieces 31 of the bezel 3 at intervals of about 120 degrees. It is done. The bezel 3 is formed so that the locking pieces 31 protrude to the back side at three positions corresponding to the locking claws 11 on the outer peripheral portion thereof. As shown in FIG. 7, the locking piece 31 is formed in a shape in which an edge of a rectangular opening hole provided in a portion protruding to the back side of the bezel 3 is cut at the rear portion. The locking piece 31 is composed of a pair of substantially L-shaped locking pieces opposed to each other, and has a shape for locking it from both sides of the locking claw 11. In this way, by making the locking piece 31 substantially L-shaped and non-annular, when the bezel 3 is injection-molded with synthetic resin, a weld line is not generated at the position of the locking piece 31.

  In addition, as shown in FIG. 8, the latching piece can also be made into the substantially L-shaped latching piece 41 of only one side. Also in this case, since the locking piece 41 is non-annular as described above, a weld line does not occur in the locking piece 41 when the bezel 3 is formed.

  In other words, since the locking pieces 31 and 41 are substantially L-shaped and non-annular, when the bezel 3 is molded by injection molding of synthetic resin, the material enters the cavity so that the material wraps around the annular portion from both sides of the locking piece. The phenomenon of flowing through does not occur. For this reason, the weld line caused by the poor fusion of the material generated at the portion where the flow heads of the materials flowing in the two directions join is not generated at the portions of the locking pieces 31 and 41, and the bezel 3 is plated. Even when a plating film is formed on the surface, a portion with poor strength does not occur.

  Therefore, when the bezel 3 is plated, there is no need to apply a plating resist solution to the locking pieces 31 and 41, and the plating resist solution application process can be eliminated, reducing the work man-hours and working time. Manufacturing cost can be reduced. Further, since the substantially L-shaped locking piece 31 is easily bent and is easily bent and locked at the time of locking, the locking pieces 31 and 41 can be prevented from cracking.
