Description

Long fin for register

The present invention is arranged in a horizontal direction at an air outlet of an air-conditioning register provided in a vehicle or the like, and is arranged so as to be rotatable in the vertical direction. The present invention relates to a register long fin that adjusts the wind direction in the vertical direction, and particularly to a register long fin provided with a decorative member at the front end of the long fin.

Conventionally, there has been proposed a register fin in which a register fin used for an air conditioning register is partially decorated.
For example, Japanese Patent Application Laid-Open No. 2010-202108 describes a register fin composed of a plate-shaped fin main body and a pair of fin covers assembled so as to sandwich the fin main body from both sides.

In such a register fin, the fin main part is coated on the entire fin main part, and the fin cover can be assembled with the fin main part exposed to the passenger compartment side so that it faces the passenger compartment side. It is possible to obtain a register fin having high design properties in which only a portion is decorated by plating or the like.

JP 2010-202108 A

However, in the conventional register fin, a plurality of engagement holes are formed in the fin main body, and a plurality of engagement claws are formed in each fin cover. The fin covers are assembled by engaging the engaging claws of the fin covers.

The conventional register fin is constructed by assembling fin covers on both sides of the fin main body, so that high rigidity can be maintained, but it inevitably increases the cost and the thickness of the register fin. Will increase. Since the register fin is used in a limited space in the register, it is not preferable to increase the thickness of the register fin, and the register fin itself becomes an obstacle of the wind blown from the register. It becomes difficult to adjust the wind direction.

Further, since the register fin is assembled by simply engaging the engaging claw portion of the fin cover with the engaging hole of the fin main body portion, when a load is applied to the register fin, the fin main body portion covers the fin cover. May come off.

Furthermore, the decoration of the register fins is performed by plating the entire fin main body part and exposing a part of the fin main body part from each fin cover to the passenger compartment side. It is very wasteful to apply plating or the like to the entire structure, which also leads to high costs.

The present invention has been made to solve the above-described problems in the prior art, and it is possible to adjust the wind direction of the wind appropriately by forming a thin thickness while maintaining high rigidity, and a decorative member. An object of the present invention is to provide a low-cost long fin for a register that can reliably prevent the detachment from the fin body.

In order to achieve the above object, the long fin for a register according to claim 1 of the present application is rotatably disposed between a pair of side walls opposed to each other by a retainer in the register, from the register toward the outside. A long fin for a register that adjusts the wind direction of the blown wind in the vertical direction, and is provided at a resin-like long fin body formed in a plate shape and a front edge of the long fin body. A decorative member made of resin, and is formed by two-color molding in which the decorative member is secondarily formed on the long fin body after primary molding of the elongated fin body, and is long at the time of the primary molding. The long fin body is formed with a groove portion that enters inward from the front edge thereof, and at the central portion in the length direction of the long fin body is formed with a gate hole through which the resin of the decorative member flows. Next molding The resin of the decorative member is characterized in that it is introduced into the groove from the gate hole.

The long fin for a register according to claim 2 of the present application is the long fin for a register according to claim 1, wherein the long fin body is made of glass fiber reinforced resin.

When the long fin body and the decorative member are molded in two colors to form the long fin for the register, the long fin for the register according to claim 1 is formed at the time of the primary molding of the long fin main body. The elongated fin body is formed with a groove that enters the inner side from the front edge thereof, and a gate hole into which the resin of the decorative member flows is formed at the center in the longitudinal direction of the elongated fin body. Since the resin for the decorative member flows into the groove portion from the gate hole during the secondary formation of the decorative member with respect to the long fin body, the decorative member is firmly formed by the groove portion at the front edge of the long fin body. The decorative member can be surely prevented from being detached from the elongated fin main body, and any color of the decorative member resin can be used. Molding It can be.

Further, the gate hole formed in the long fin body is formed at the center in the length direction of the long fin body, and the resin for the decorative member has groove portions from the gate hole toward both sides of the gate hole. Since the resin flow pressure is equalized on both sides of the gate hole, the decorative member resin is evenly distributed in the groove with good fluidity while keeping the resin flow pressure low. Can be made. Thereby, the moldability of the decorative member can be improved and the occurrence of molding unevenness can be prevented.

The long fin body is formed in a single plate shape, and the decorative member is only fixed to the front edge of the long fin body, so that the entire length of the register long fin is made thin. be able to. The long register fins configured as described above can appropriately adjust the wind direction of the wind without becoming an obstacle of the wind blown from the register.

As described above, the long fin for the register is composed of the long fin main body and the decorative member fixed to the front end edge of the long fin. A long fin can be realized.

In the long fin for a register according to claim 2 of the present application, since the long fin main body is formed of glass fiber reinforced resin, high rigidity can be maintained even when the long fin main body is thinly formed. In addition, even when a load is applied, deformation or the like does not occur.

A pair of registers 3 according to the present embodiment is disposed below the display. A pair of registers 4 are also provided on the left and right sides of the instrument panel 1, but these registers 4 do not use long fins and have a known configuration.

2, the register 3 according to the present embodiment has a rectangular shape when viewed from the front, and includes a retainer 6 having a cylindrical ventilation portion 5 having a substantially rectangular cross section. Various components constituting the register 3 are accommodated in the retainer 6, and an air outlet 7 communicating with the ventilation portion 5 is formed on the front side (the front side in FIG. 2) of the retainer 6. Has been.

Between the pair of side walls 8 and 8 (only one side wall 8 is shown in FIG. 2) which defines the air outlet 7 in the retainer 6 and opposes each other in the left-right direction, the long length according to the present embodiment. The fin 9 is rotatably arranged. The long fins 9 are used to adjust the wind direction of the wind blown outward from the air outlet 7 in the vertical direction. A knob 10 that is slidably attached to the long fin 9 is provided at a substantially central portion of the long fin 9. As shown in FIG. 2, the knob 10 is composed of an upper knob member 10A and a lower knob member 10B, and is inserted between a lower portion of the upper knob member 10A and an upper portion of the lower knob member 10B. A long fin 9 is inserted into a recess (described later) so that the knob 10 can slide.
The configuration of the knob 10 will be described later.

A vertical fin mechanism 12 for rotating a plurality of vertical fins 11 integrally in the left-right direction via a known link mechanism is disposed behind the long fin 9 at the air outlet 7. Each vertical fin 11 of the vertical fin mechanism 12 is rotated in the left-right direction corresponding to the slide in the left-right direction of the knob 10 by a known gear mechanism provided between the knob 10 and blown out from the air outlet 7. It is used to adjust the wind direction of the generated wind in the left-right direction.

Subsequently, the configuration of the long fin 9 will be described with reference to FIGS. The long fin 9 includes a resin-made long fin main body 13 formed in a plate shape and a resin decorative member 14 provided at the front end edge of the long fin main body 13.

Support shafts

15, 15 extend from both ends of the elongated fin body 13, and each of these support shafts 15 is provided with a support hole (not shown) formed in each

side wall

8, 8 of the air outlet 7. ) Is supported so as to be rotatable. In addition,

knob support portions

16 and 16 for slidably supporting the knob 10 are formed at the rear end portion of the long fin body 13, and each knob support portion 16 has, as shown in FIG. A concave groove 17 is provided.

The long fins 9 configured as described above are formed by so-called two-color resin formation. In order to mold the long fin 9 in two colors, first, polybutylene terephthalate (PBT) mixed with glass fiber is poured into a primary mold for molding the long fin main body 13 to form the long fin main body 13. Is primary molded. The long fin body 13 formed in this way is shown in FIGS.

In the elongated fin main body 13 after the primary molding, as shown in FIG. 6, a groove 18 is formed so as to enter the inner direction from the front end. The groove portion 18 is a cavity for secondary molding of the decorative member 14, and is formed wide at the central portion 19 in the length direction of the long fin body 13, and narrower as it goes from the central portion 19 to both end portions. Is formed. A gate hole 20 that communicates with the groove 18 is formed in the central portion 19.

The long fin body 13 that has been primarily molded as described above is disposed in the secondary forming mold, and a resin material in which aluminum powder is kneaded with polybutylene terephthalate is injected from the gate hole 20. As a result, the resin material flows from the gate hole 20 through the central portion 19 of the groove portion 18 into both end portions of the long fin body 13.

At this time, as shown in FIG. 5 and FIG. 6, a groove portion 18 is formed which enters inward from the front end edge of the long fin body 13 at the time of primary molding of the long fin body 13 and the long fin body 13. A gate hole 20 into which the decorative member molding resin material flows is formed in the central portion 19 in the length direction of the main body 13, and the decorative member resin material is gated during the secondary formation of the decorative member 14 with respect to the elongated fin main body 13. Since it flows into the groove portion 18 from the hole 20, the decoration member 14 is firmly fixed to the long fin body 13 at the groove portion 18 at the front end edge of the long fin body 13. Separation from the long fin body 13 can be reliably prevented, and two-color molding can be performed regardless of the resin material used for the decorative member.

Further, the gate hole 20 formed in the long fin body 13 is formed in the central portion in the length direction of the long fin body 13, and the resin for the decorative member passes from the gate hole 20 to both sides of the gate hole 20. Since the length of the resin flow path is equalized on both sides of the gate hole 20, the resin for the decorative member is allowed to flow with good fluidity while keeping the resin flow pressure low. It can be distributed evenly throughout. Thereby, the moldability of the decoration member 14 can be improved and the occurrence of molding unevenness can be prevented.

Since the long fin body 13 is formed in a single plate shape and the decorative member 14 is only fixed to the front edge of the long fin body 13, the total thickness of the long fin 9 is reduced. It can be formed thin. The long fins 9 configured as described above can appropriately adjust the wind direction of the wind without becoming an obstacle of the wind blown from the register 1.

As described above, the long fin 9 is composed of the long fin body 13 and the decorative member 14 fixed to the front end edge thereof. The number of parts is minimized, and the cost is low and the decorative property is high. The long fin 9 can be realized.

Since the long fin body 13 is formed of a glass fiber reinforced resin in which glass fibers are mixed into polybutylene terephthalate, it can maintain high rigidity even when the long fin body 13 is thinly formed. Even when a load is applied, deformation or the like does not occur.

Next, the configuration of the knob 10 that is slidably supported by the long fin 9 will be described with reference to FIGS. Here, as described with reference to FIG. 2, the knob 10 includes the upper knob member 10 A and the lower knob member 10 B, and holds the knob 10 slidably with respect to the long fin 9. Since the upper knob member 10A basically plays the main role, the following description will focus on the upper knob member 10A.
10 A of upper knob members are formed in the substantially square shape by planar view, and are integrally formed from the rear part 22 which inclined upward toward the back side continuously from the horizontal part 21 and a horizontal part. A decorative member 23 is provided at the front edge of the horizontal portion 21 so as to surround the front edge.

As shown in FIG. 8, an insertion recess 24 into which the long fin 9 is inserted is formed on the back surface of the upper knob member 10A. In the insertion recess 24, as shown in FIG. 9, both

end portions

25, 25 of the decorative member 23 are arranged on the front side, and the projecting sliding formed on both sides of the lower portion of the rear portion 22 on the rear side. Protrusions 26 are disposed.

In order to slidably hold the upper knob member 10 A with respect to the long fin 9, the sliding

protrusions

26, 26 of the upper knob member 10 A are formed in the

concave grooves

17, 17 formed on the back surface of the long fin 9. While being inserted, it is inserted into the insertion recess 24 of the upper knob member 10A. As a result, both

end portions

25, 25 of the decorative member 23 provided on the upper knob member 10A abut on the decorative member 14 provided on the front end side of the long fin 9, and each sliding projection 26 is in the corresponding groove. 17 is inserted and held. As a result, the upper knob member 10 A is slidably held on the long fin 9 within the range of the length of each recess 17.

The upper knob member 10A configured as described above is formed by forming two colors of resin as in the case of the long fins 9 described above. In order to mold the upper knob member 10A in two colors, first, a resin material formed by mixing polybutylene terephthalate (PBT) and ABS resin is poured into a primary mold for molding the knob body excluding the decorative member 23. Primary molding of the knob body. In the knob body molded in this way, a groove for the decorative member 23 is integrally formed, and the groove serves as a cavity for secondary molding of the decorative member 23.

The knob body primary-molded as described above is arranged in a secondary mold, and a resin material in which aluminum powder is kneaded with polybutylene terephthalate is provided near the end 25 of the decorative member 23 in the secondary mold. Inject from the gate hole. As a result, the resin material flows into the groove of the knob body from the gate hole.

At this time, at the time of the primary molding of the knob body, a groove for the decorative member 23 is formed in the knob body, and the resin material for the decorative member flows into the groove portion from the gate. It is firmly fixed to the knob body at the groove at the front edge of the rim, so that it is possible to reliably prevent the decorative member 23 from being detached from the knob main body, and how the resin material for the decorative member is used. Even a simple resin material can be two-color molded.

As described above, the upper knob member 10A is composed of the knob main body and the decorative member 23 fixed to the front end edge of the upper knob member 10A. Can be realized.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the above-described embodiment, a resin material in which polybutylene terephthalate (PBT) is reinforced with glass fiber is used as a molding resin material for the long fin body 13, but the present invention is not limited to this. As long as the rigidity required for the long fins 9 can be maintained, for example, a resin material in which polytrimethylene terephthalate resin (PTT) is reinforced with glass fiber, polycarbonate resin (PC), or the like can be used.

Moreover, in the long fin 9 which concerns on the said embodiment, when performing the secondary shaping | molding of the decoration member 14 with respect to the long fin main body 13 after a primary shaping | molding, it decorates on the front end surface of the long fin main body 13 The secondary molding of the decorative member 14 was performed so that the member 14 was in close contact, but in this case, burrs and the like on the molding occurred on both the upper and lower surfaces in the vicinity of the front end surface of the long fin body 13. Since the appearance may be deteriorated, the undercut portion 30 may be formed at the time when the long fin body 13 is primarily formed as shown in FIG. If it does in this way, the burr | flash etc. on a shaping | molding will generate | occur | produce in the slope 31 of the undercut part 30, the secondary formation of the decoration member 14 is performed, the elongate fin 9 is formed, the front side of the decoration member 14 When (from the right side in FIG. 12) is viewed from the direction of arrow A, the burrs and the like generated on the slope 31 are shielded by the decorative member 14 so that they cannot be seen at all, and the appearance is good.

The present invention makes it possible to adjust the wind direction appropriately by forming a thin thickness while maintaining high rigidity, and to reliably prevent the decorative member from detaching from the fin body. A long fin for a register with low cost can be provided, and its industrial effect is great.
