Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the fins for a register described in Patent Document 1 require an adhesion step to adhere the decorative member with an adhesive, resulting in a problem of high manufacturing cost. Further, although the fins for a register described in Patent Document 2 can attach the decorative member without requiring an adhesion step, the decorative member is fitted by a protrusion and a recess, and is simply pressed against the edge of the fin from the front to fit the protrusion and the recess. Therefore, when the decorative member is touched by an operator or receives an external force, or due to aging or the like, if the mutual fitting becomes loose, the decorative member may come off.

[0006] The problem to be solved by the technology of this specification is made in view of the above points, and an object is to provide a fin for a register that can easily attach a decorative member to the fin and can effectively prevent the decorative member from accidentally coming off.

Means for Solving the Problem

[0007] In the fin for a register according to an embodiment of this specification, an air outlet is provided at the downstream end of a retainer having a ventilation path, and fins are pivotally supported at the air outlet via a support shaft so as to be rotatable. In the fin for a register in which a decorative member is fitted along the longitudinal direction of the fin at the downstream side edge of the fin, The decorative member is formed in a substantially semi-cylindrical shape with an arc on the downstream side, and an accommodation recess for accommodating and fitting the downstream side edge of the fin is provided inside. A plurality of partition walls are provided in the short direction in the accommodation recess, and locking claws that are inserted into and locked to the fin project rearward near both ends in the longitudinal direction, respectively. The fin is provided with a fitting convex portion that is fitted into the accommodation recess at the downstream side edge portion. The fitting convex portion is provided with a plurality of notch recesses in which the fitting convex portion is notched, and locking walls that contact the partition walls project forward in the notch recesses. Insertion holes into which the locking claws are inserted are provided rearward at the downstream side edge portions near both ends in the longitudinal direction, respectively. On the side where each of the locking wall of the fin and the partition wall of the decorative member is in contact, a locking recess and a locking convex portion are provided so as to be mutually lockable.

[0008] Here, the front and rear of the register indicate that the downstream side where the adjusted air flows is the front and the upstream side is the rear. According to the fins for the register according to the embodiment of the present specification, the decorative member can be attached to the fins by inserting the locking claws near both longitudinal ends of the decorative member into the insertion holes of the fins. Therefore, the fins for the register can easily attach the decorative member to the fins. Further, the fitting convex portion of the fin fits into the accommodation concave portion of the decorative member, and the locking concave portion and the locking convex portion provided on the sides where the locking wall of the fin and the partition wall of the decorative member are in contact with each other are fitted and locked to each other. Therefore, the decorative member can be firmly fitted to the fins, and accidental detachment of the decorative member can be effectively prevented.

[0009] Here, in the fins for the register, a through hole that penetrates outward in the longitudinal direction of the fin is communicatively provided from the rear end of the insertion hole of the fin. A configuration can be adopted in which a protrusion is provided at the rear end of the locking claw of the decorative member toward the outside in the longitudinal direction of the decorative member.

[0010] According to this, when the decorative member is fitted to the fins, the protrusion enters the through hole, and accidental detachment of the decorative member can be effectively prevented.

[0011] Further, in the fins for the register, a configuration can be adopted in which an inclined surface that narrows the insertion hole from the outside toward the rear is provided on the outer side behind the insertion hole.

[0012] According to this, when the decorative member is fitted to the fins, the inclined surface can elastically deform the locking claw and the protrusion inward, so that the decorative member can be easily attached to the fins.

[0013] Further, in the fins for the register, a configuration can be adopted in which an engaging concave portion and an engaging convex portion for positioning are provided on the inner surfaces of the fitting convex portion of the fin and the accommodation concave portion of the decorative member so as to be mutually engageable.

[0014] According to this, when the decorative member is fitted to the fin, the positioning engaging concave portion and the engaging convex portion can facilitate the positioning of the decorative member on the fin.

[0015] Further, in the above register, the fitting convex portion can be configured such that a rib shape is provided in the thickness direction of the fitting convex portion.

[0016] According to this, the rib shape can act as a contact rib of the decorative member, and positioning during assembly and rattling prevention of the decorative member can be performed.

Mode for Carrying Out the Invention

[0019] Hereinafter, the fin for a register according to the embodiment of this specification will be described with reference to FIGS. 1 to 12. Note that the scope of the present invention is not limited to the scope disclosed in the embodiment. Also, in this specification, the direction of the register and the fin for the register is as shown in FIG. 1. The side having the air outlet 81 of the bezel 8 is taken as the front, and the air inlet 22 side of the ventilation path 21 in the retainer 2 is taken as the rear. The up, down, left, and right are the up, down, left, and right when the register is viewed from the front side. In the illustration, F represents the front, B represents the rear, U represents the upper, D represents the lower, L represents the left, and R represents the right. Also, from the adjusted air flow, the front may be expressed as the downstream side and the rear as the upstream side. Further, based on the center of the fin 31 or the register, it may be expressed as the inside or the outside.

[0020] As shown in FIGS. 1 and 2, the fin for a register according to the embodiment is used for the front movable louver 3 provided at the air outlet 81 of the register. Among the three fins 31 constituting the front movable louver 3, the decorative members 50 are respectively fitted to the downstream edge portions of the upper and lower fins 31.

[0021] As shown in FIGS. 1 and 2, the retainer 2 serving as the housing of the register is a substantially rectangular tubular housing provided with a ventilation path 21 inside. A louver housing portion 23 is provided on the front side, and a front movable louver 3 for adjusting the wind direction up and down is disposed on the air outlet 81 side in the louver housing portion 23, and a rear movable louver 7 for adjusting the wind direction left and right is disposed behind (inside) it.

[0022] The front movable louver 3 has three fins 31 arranged in the left - right direction (horizontal direction) with an interval vertically. Each fin 31 is rotatably held with respect to the bearing plates 39 arranged on the left and right via the support shafts 31a on both sides. A link bar 38 is connected to the connecting shaft 31b protruding from one end of each fin 31, and all the fins 31 can change their directions synchronously up and down. An operation knob 11 is externally fitted to the central fin 31 so as to be slidable left and right. When the operator places a finger on the operation knob 11 to tilt the front movable louver 3 up and down and slide it in the left - right direction, the rear movable louver 7 described later is tilted left and right.

[0023] As shown in FIGS. 1, 3, and 4, among the three fins 31 of the front movable louver 3, decorative members 50 are fitted to the downstream - side ends of the upper and lower fins 31 along the longitudinal direction of the fins 31. Each component constituting the register is formed of a black - based synthetic resin, and the decorative member 50 is, for example, silver - plated as a color different from the black - based system.

[0024] As shown in FIGS. 11 and 12, the decorative member 50 has a substantially semi - cylindrical shape with the left - right direction as the axial direction, the front side forming a semi - circle of an arc, and a receiving recess 51 provided at the rear side (upstream side) which is opened by cutting the cylinder in the axial direction. The receiving recess 51 is fitted to the fitting convex portion 32 of the fin 31 to accommodate the fitting convex portion 32. Locking claws 55 inserted into and locked to the fin 31 protrude rearward near both longitudinal ends of the decorative member 50, and two partition walls 53 are provided in the short - hand direction in the receiving recess 51 between the locking claws 55. The partition walls 53 are provided so as to trisect the receiving recess 51 between the locking claws 55 left and right.

[0025] As shown in Fig. 11, the locking claws 55 project rearward from near both ends of the decorative member 50, are inserted into the insertion holes 34 of the fins 31, and lock the decorative member 50 to the fins 31. A reinforcing rib 55b connecting the locking claws 55 and the inner side of the decorative member 50 is provided on the inner side in the left-right direction on the root side of the front end of the locking claws 55. The reinforcing rib 55b prevents the locking claws 55 from breaking against the lateral deflection of the locking claws 55 when the decorative member 50 is fitted to the fins 31. A protrusion 55a is provided extending outward in the left-right direction from the rear end of the locking claws 55. As shown in Fig. 4, the protrusion 55a can enter the through hole 34b of the fin 31 when the decorative member 50 is fitted to the fin 31, effectively preventing the decorative member 50 from accidentally coming off the fin 31.

[0026] As shown in Figs. 11(D), (E), and 12, the partition wall 53 is a partition provided in the short side direction within the accommodation recess 51. The accommodation recess 51 is separated into three by the two partition walls 53. Locking protrusions 53a capable of locking to the locking recesses 33a of the locking walls 33 of the fins 31, which will be described in detail later, are provided on the outer wall surfaces in the left-right direction of the partition wall 53. By the locking protrusions 53a locking to the locking recesses 33a of the locking walls 33, the decorative member 50 can be firmly fitted to the fins 31, preventing the decorative member 50 from coming off the fins 31.

[0027] An engaging protrusion 57 projecting downward is provided on the upper inner surface of the middle accommodation recess 51 among the three accommodation recesses 51 arranged side by side left and right. By fitting the engaging protrusion 57 into an engaging recess 37 provided above the fitting protrusion of the fin 31, which will be described later, the positioning of the decorative member 50 to the fin 31 can be facilitated.

[0028] The fin 31 is a flat plate body that is long in the left - right direction and can be inclined vertically around the support shaft 31a. As shown in FIGS. 1 and 3, a decorative member 50 is fitted on the downstream side (front side) in the longitudinal direction (left - right direction). As shown in FIG. 10, insertion holes 34 into which the locking claws 55 of the decorative member 50 are inserted are respectively provided on the downstream - side (front - side) edges near both ends in the longitudinal direction of the fin 31, facing backward. As shown in FIG. 10, on the downstream - side edge of the fin 31 connecting the left - and - right support shafts 31a, a fitting projection 32 that fits into the accommodation recess 51 of the decorative member 50 is provided. The fitting projection 32 is provided with two notch recesses 33b that notch the fitting projection 32 so as to trisect the fitting projection 32 in the left - right direction. In the notch recesses 33b, locking walls 33 that contact the left - and - right - direction outer wall surfaces of the partition wall 53 of the decorative member 50 project toward the downstream side (front side).

[0029] As shown in FIG. 4, the insertion hole 34 is for inserting the locking claw 55 of the decorative member 50 to lock the decorative member 50 to the fin 31. As shown in FIG. 12(B), a through - hole 34b that penetrates outward in the longitudinal direction of the fin 31 is communicatively provided from the rear end of the insertion hole 34. When the decorative member 50 is fitted to the fin 31, the protrusion 55a of the locking claw 55 of the decorative member 50 enters the through - hole 34b, so that the decorative member 50 can be effectively prevented from being inadvertently detached from the fin 31. An inclined surface 34c that narrows the insertion hole 34 from the outside toward the rear is provided on the outer side rear of the insertion hole 34. Thereby, when inserting the locking claw 55 of the decorative member 50 into the insertion hole 34 during fitting the decorative member 50 to the fin 31, the inclined surface 34c can elastically deform the locking claw 55 together with the protrusion 55a inward, so that the decorative member 50 can be easily fitted to the fin 31.

[0030] The locking wall 33 has a locking recess 33a that protrudes toward the downstream side (front side) within the notch recess 33b and engages with the locking protrusion 53a of the partition wall 53 of the decorative member 50 on the inner side in the left - right direction of the locking wall 33. When the decorative member 50 is fitted onto the fin 31, as shown in FIG. 4, the partition wall 53 of the decorative member 50 contacts the inner side in the left - right direction of the locking wall 33, and the locking protrusion 53a of the partition wall 53 is fitted and locked into the locking recess 33a of the locking wall 33. Therefore, the decorative member 50 can be firmly fitted onto the fin 31.

[0031] The fitting protrusions 32 are cut out by two notch recesses 33b, and three fitting protrusions 32 are formed. When the decorative member 50 is fitted onto the fin 31, as shown in FIGS. 12 and 4, the three fitting protrusions 32 are respectively received and fitted into the three receiving recesses 51 of the decorative member 50. Also, an engaging recess 37 is provided above the middle fitting protrusion among the three fitting protrusions 32 arranged side - by - side left - right, which engages with the engaging protrusion 57 provided on the inner surface of the receiving recess 51 of the fin 31. By fitting the engaging protrusion 57 into the engaging recess 37, the fin 31 can be easily positioned when the decorative member 50 is fitted onto the fin 31.

[0032] As shown in FIGS. 10(D) and (E), rib shapes 32a are provided one by one above and below the left - right end fitting protrusions 32 and two by two above and below the central fitting protrusion 32 from the thickness direction of the fitting protrusion 32 to the front side of the fin 31. The rib shapes 32a act as abutting ribs of the decorative member 50, performing positioning in the up - down and front - rear directions during assembly and preventing rattling of the decorative member 50 after assembly.

[0033] To attach the decorative member 50 to the fin 31, first, as shown in FIG. 12(A), the decorative member 50 is placed in front of the fin 31 so that the locking claws 55 protruding rearward from the decorative member 50 are inserted into the insertion holes 34 of the fin 31.

[0034] Next, attach the decorative member 50 to the fin 31 such that the locking claw 55 is inserted into the insertion hole 34, and the two left and right partition walls 53 of the decorative member 50 are fitted into the notch recesses 33b inside the locking wall 33 of the fin 31. At this time, by engaging the engaging convex portion 57 of the decorative member 50 with the engaging concave portion 37 of the fin 31, the attachment position of the decorative member 50 with respect to the fin 31 is determined, and the partition wall 53 is guided to fit into the notch recess 33b inside the locking wall 33, enabling easy positioning and attachment of the decorative member 50 to the fin 31.

[0035] By strongly pressing the decorative member 50 against the fin 31, the locking claw 55 penetrates into the back (rear side) of the insertion hole 34. When it penetrates and the tip of the locking claw 55 abuts against the inclined surface 34c on the outer side of the rear of the insertion hole 34, the locking claw 55 is elastically deformed inward together with the protrusion 55a, and the protrusion 55a enters the through hole 34b that penetrates outward from the rear end of the insertion hole 34, whereby the decorative member 50 is fitted to the fin 31.

[0036] At this time, the rib shape 32a provided on the fitting convex portion 32 of the fin 31 fits into the accommodation recess 51 of the decorative member 50, and the rib shape 32a provided on the front side of the fin 31 from the fitting convex portion 32 determines the vertical and front-rear attachment positions of the decorative member 50 with respect to the fin 31 and prevents rattling of the decorative member 50.

[0037] During fitting, the decorative member 50 is such that the inclined surface 34c causes the locking claw 55 to be passively elastically deformed inward, and the protrusion 55a crosses the inclined surface 34c and enters the through hole 34b, so that the decorative member 50 can be easily attached to the fin 31. Also, since the protrusion 55a enters the through hole 34b, the fin 31 can effectively prevent accidental detachment of the decorative member 50.

[0038] When the decorative member 50 is fitted onto the fin 31, the fitting convex portion 32 of the fin 31 is fitted into the accommodation recess 51 of the decorative member 50, and the locking convex portion 53a and the locking concave portion 33a provided on the sides where the partition wall 53 of the decorative member 50 and the locking wall 33 of the fin 31 are in contact with each other are fitted and locked to each other. Therefore, the decorative member 50 can be firmly fitted onto the fin 31.

[0039] As shown in FIG. 2, the rear movable louver 7 has five rear fins 71 arranged at intervals in the vertical direction. Each rear fin 71 is rotatably held with respect to the bearing plates 79 arranged vertically via upper and lower support shafts 71a. Further, a link bar 78 is connected to a connecting shaft 71b protruding from one end of each rear fin 71, and all the rear fins 71 are structured such that their directions can be changed left and right synchronously.

[0040] On the front portion of the central rear fin 71 of the rear movable louver 7, an engaging portion 77 such as a rack member is provided, which engages with an engaged portion 12 such as a rack member provided at the rear portion of the operation knob 11. When the operation knob 11 is slid left and right, the direction of the rear fins 71 of the rear movable louver 7 is adjusted left and right.

[0041] Thereby, the operation knob 11 adjusts the direction of each fin 31 of the front movable louver 3 up or down by its vertical rotation operation, and adjusts the left - right direction of the rear fins 71 of the rear movable louver 7 left or right via the engaging portion 77 by the left - right sliding operation of the operation knob 11.

[0042] The register having the above - described configuration is mounted on an instrument panel or a dashboard portion inside an automobile such that the air inlet 22 at the rear end of the retainer 2 is connected to a ventilation duct (not shown). Although the illustration at the time of mounting is omitted, a bezel 8 provided with the air outlet 81 of the register having the above - described configuration is fitted and mounted on the instrument panel or the dashboard. The air sent from the ventilation duct is blown out through the air outlet 81 from the ventilation path 21 inside the retainer 2.

[0043] When adjusting the blowing direction of the air upward or downward, when the operation knob 11 is operated upward or downward, the fins 31 of the front movable louver 3 rotate about the left and right support shafts 31a thereof, and the direction thereof changes vertically, and the blowing direction of the air is adjusted vertically. When adjusting the blowing direction of the air left and right, when the operation knob 11 is slid right or left, the rear fins 71 of the rear movable louver 7 rotate about the upper and lower support shafts 71a thereof, and the left and right directions thereof change within a predetermined angle range, and the blowing direction of the air is adjusted left and right.

[0044] According to the register according to the embodiment of the present specification, by inserting the locking claws 55 near both ends in the longitudinal direction of the decorative member 50 into the insertion holes 34 of the fins 31, the decorative member 50 can be attached to the fins 31. Therefore, the fins 31 for the register can easily attach the decorative member 50 to the fins 31. Further, the fitting convex portion 32 of the fins 31 is fitted into the accommodation recess 51 of the decorative member 50, and the locking convex portion 53a and the locking concave portion 33a provided on the side where the partition wall 53 of the decorative member 50 and the locking wall 33 of the fins 31 are in contact with each other are fitted and locked to each other. Therefore, the decorative member 50 can be firmly fitted to the fins 31, and accidental detachment of the decorative member 50 can be effectively prevented.

[0045] In addition, as other embodiments, the fins for the register of the embodiment can be implemented in the following forms.

[0046] For the fins (fins 31) for the register of the embodiment, although the decorative member 50 is formed of a black synthetic resin and is silver-plated for decoration, the decoration is not limited to silver plating, and other color plating or painting can be performed. Further, the decorative member 50 can have a color different from that of other members by changing the color of the synthetic resin itself to be formed.

[0047] For the fins (fins 31) for the register of the embodiment, although the shape on the downstream side including the decorative member 50 is substantially linear, the shape on the downstream side including the decorative member 50 can be curved or have an angle.
