Description

[Technical field]

[0001] The technical field of the register described in this specification relates to a register used in an air outlet for ventilation or air conditioning in an automobile interior, in which a barrel and a movable louver are arranged in front of and behind each other within the ventilation passage of a retainer. [Background technology]

[0002] A widely used register for adjusting air blowing in a vehicle cabin is one in which a barrel and a movable louver are arranged in front of and behind each other inside a retainer that forms an air passage, and when air is blown out from the air outlet, the angle of the blades of the barrel and the rear fins of the movable louver are changed to adjust the air blowing direction up, down, left, and right. As an example of this type of register, the following Patent Document 1 describes a register with an elongated air outlet that is long in the longitudinal direction and short in the lateral direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-70399 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the conventional register described in Patent Document 1 has three blades arranged in the short direction on the barrel, with the middle one crossing the center of the air outlet, and the blade crossing the center is equipped with an operation knob for adjusting the angle of the barrel and the rear fin of the movable louver. Therefore, the conventional register had the problem that the blade crossing the center of the air outlet mars the design and has a large impact on air conditioning performance, such as increasing pressure loss.

[0005] The present invention has been made in consideration of the above-mentioned points, and has an object to provide a register that can improve design and reduce the impact on air conditioning performance. [Means for solving the problem]

[0006] The register according to the embodiment of the present specification is provided with an elongated air outlet that is long in the longitudinal direction and short in the lateral direction at the downstream end of an air passage, and a barrel that can be tilted in the lateral direction of the air outlet and a movable louver having a rear fin that can be tilted in the longitudinal direction are arranged in front and rear in the air passage from the downstream side. The barrel is a frame body in which an air guide passage is provided in the front-rear direction, and is formed of two longitudinal blades arranged at both ends in the lateral direction and two lateral side walls arranged at both ends in the lateral direction, A connecting frame that connects the blades together is provided in the short direction inside the barrel, and an operating knob is provided on the front side of the connecting frame for tilting the barrel and the movable louver to adjust the air blowing direction.

[0007] Here, the front and rear of the register indicate the downstream side where the conditioned air flows into the vehicle cabin as the front, and the upstream side where the conditioned air is introduced as the rear. According to the register according to the embodiment of the present specification, the barrel is formed of a frame body in which an air guide passage is provided, and the operation knob is provided on the front side of a connecting frame that connects the short sides of the barrel inside the frame body. Therefore, when viewed from an operator inside the vehicle cabin, the rear connecting frame is hidden behind, and the operation knob appears to be floating inside the barrel frame body, improving the design. In addition, since only the connecting frame equipped with the operation knob is provided inside the barrel air guide passage, the impact on air conditioning performance can be reduced.

[0008] Here, in the register, the operation knob is provided with an operation shaft portion on the upstream side for tilting the movable louver, a knob support portion is provided on the connecting frame so as to be long in the longitudinal direction, and a long and narrow opening is provided on the knob support portion so as to be long in the longitudinal direction, and the operation knob is inserted into the long and narrow opening so as to be slidable in the longitudinal direction; The movable louver has a linking portion to which the operating shaft portion is linked, provided on one of the rear fins, The operating shaft portion of the operating knob is linked to the linking portion, and when the operating knob is slid in the longitudinal direction, the orientation of the rear fins of the movable louver is adjusted in the longitudinal direction.

[0009] With this, the operating shaft portion of the operating knob is linked to the linking portion of the movable louver, and when the operating knob is slid in the longitudinal direction, the orientation of the rear fins of the movable louver can be adjusted in the longitudinal direction.

[0010] In the register, the operation knob may be provided so as to cover and conceal the elongated opening from the front side.

[0011] According to this, the operation knob covers and conceals the elongated opening from the front side, thereby improving the design.

[0012] In the register, a recess having an arc-shaped cross section in the front-rear direction may be formed on the inner surface of the blade.

[0013] This can improve the directionality of the airflow when the barrel is tilted in the short direction relative to the air outlet.

[0014] In the register described above, the connecting frame may be arranged at a position overlapping one of the rear fins in the front-rear direction when the movable louver is in a neutral state.

[0015] With this, when viewed from the front, the connecting frame overlaps with one of the rear fins, thereby improving the design.

[0016] In the register, the frame body forming the barrel is composed of a front frame member and a rear frame member, and is joined at the front and rear, The connecting frame has T-shaped fixing parts at both ends, The fixing portion may be configured to be clamped and assembled between the front frame member and the rear frame member.

[0017] This allows the connecting frame to be easily assembled to the barrel. Effect of the Invention

[0018] According to the register of this specification, the operating knob appears to float within the frame of the barrel, improving the design, and since only the connecting frame with the operating knob is provided within the air guide of the barrel, the impact on air conditioning performance can be reduced.

[0020] Hereinafter, a register according to an embodiment of the present specification will be described with reference to Figs. 1 to 10. The scope of the present invention is not limited to the scope disclosed in the embodiment. As shown in Figs. 1 to 3, the register 1 according to the embodiment has an elongated air outlet 61 that is long in the left-right direction (longitudinal direction) and short in the up-down direction (short-side direction) at the downstream end of the ventilation passage 2a in the retainer 2 through which the conditioned air flows, and a barrel 3 that tilts up and down for adjusting the wind direction and a movable louver 5 having a rear fin 50 that tilts left and right are arranged in the front and rear directions in the ventilation passage 2a. The barrel 3 is a frame body in which an air guide passage 3a is provided in the front-rear direction, and is formed of two longitudinal blades 30 arranged side by side on both ends in the short-side direction, and two lateral side walls 31 arranged side by side on both ends in the longitudinal direction. A connecting frame 43 that connects the blades 30 together is provided in the short direction inside the barrel 3, and an operation knob 4 that adjusts the air blowing direction by tilting the barrel 3 and the movable louvers 5 is provided in front of the connecting frame 43. Each part that constitutes the register 1, including the operation knob 4, is made of black synthetic resin.

[0021] In this specification, the orientation of the register 1 is as shown in Figures 2 and 3, with the side having the air outlet 61 of the bezel 6 as the front, and the side of the air intake 22 of the ventilation passage 2a in the retainer 2 as the rear. Up, down, left, right and up are those when the register is viewed from the front side, and as used in the drawings, F indicates the front, B indicates the rear, U indicates the top, D indicates the bottom, L indicates the left, and R indicates the right. Also, based on the regulated air flow, the front may be expressed as the downstream side and the rear as the upstream side. Furthermore, based on the ventilation passage 2a in the retainer 2 or the air guide passage 3a in the barrel 3, the inside and outside may be expressed.

[0022] 2 and 3, the retainer 2, which is the housing of the register, is a generally rectangular cylindrical housing with an air passage 2a provided inside, with a louver housing section 23 provided at the front, a barrel 3 that adjusts the air direction up and down disposed on the downstream side (front side) of the louver housing section 23, and a movable louver 5 that adjusts the air direction left and right disposed on the upstream side (rear side) of the barrel 3. The blades 30 of the barrel 3 and the rear fins 50 of the movable louver 5 are disposed in perpendicular directions.

[0023] 4, the barrel 3 is composed of a frame body in which an air guide passage 3a is provided in the front-rear direction, and the blades 30 in the left-right direction (longitudinal direction) are arranged on both upper and lower ends, and the blades 30 are connected to each other at both left and right ends by side walls 31 to form a frame body. The barrel 3 is disposed immediately inside the air outlet 61, and a tilting shaft 31a is provided on each of the left and right side walls 31, and the barrel 3 is axially supported by the tilting shaft 31a to be tiltable in the up-down direction (short side direction) relative to the louver housing section 23.

[0024] 9, the blades 30 have recesses 34 that are recessed in an arc-shaped cross section in the front-rear direction and extend in the left-right direction (longitudinal direction) on the air guide passage 3a side, which is the inner surface (the lower surface in the upper blade 30, and the upper surface in the lower blade 30) of the barrel 3. As a result, when the barrel 3 is tilted up-down (transverse direction), the air flowing in the air guide passage 3a is guided in the air blowing direction by the recesses 34, so that the register 1 can improve the directivity of the air blowing.

[0025] As shown in Figs. 2 and 4, the barrel 3 is provided with a connecting frame 43 on the left side in the up-down direction to connect the upper and lower blades 30, and the operation knob 4 for adjusting the air blowing direction by tilting the barrel 3 and the movable louver 5 is provided on the front side of the connecting frame 43. As shown in Figs. 5 and 6, the connecting frame 43 is provided with a knob support portion 43c that is long in the left-right direction, and the knob support portion 43c is provided with a long and narrow opening 43a that opens long in the left-right direction, and a flange 4a that is extended to the rear of the operation knob 4 is inserted into the long and narrow opening 43a from the front. The operation knob 4 (flange 4a) is accommodated in the long and narrow opening 43a so as to be slidable left and right. The operation knob 4 is disposed on the front side of the connecting frame 43 and covers the long and narrow opening 43a from the front side. Therefore, when viewed from the operator inside the vehicle cabin, the long and narrow opening 43a is covered by the operation knob, and the connecting frame 43 disposed on the rear side of the operation knob 4 is hidden behind the operation knob 4 and is difficult to see. Therefore, as shown in FIG. 2, the operation knob 4 appears to be floating within the frame of the barrel 3, thereby improving the design of the register 1.

[0026] As shown in Fig. 3, the frame body forming the barrel 3 is composed of a front frame member 35 and a rear frame member 36, and is formed by joining the front frame member 35 and the rear frame member 36 to each other from the front to the rear. A plurality of locking claws 35a are provided on the rear side of the front frame member 35, and a plurality of locking claw receivers 36a corresponding to the locking claws 35a are provided on the front side of the rear frame member 36, and the front frame member 35 and the rear frame member 36 are joined by the locking claws 35a being locked to the locking claw receivers 36a. Clamping holes 35b, 36b for clamping the connecting frame 43 are provided on the upper and lower left sides of the front frame member 35 and the upper and lower left sides of the rear frame member 36, respectively, and T-shaped fixing portions 43b at both the upper and lower ends of the connecting frame 43 are clamped by the clamping holes 35b, 36b, and the connecting frame 43 is clamped and assembled to the barrel 3.

[0027] As shown in Fig. 5, the size of the operation knob 4 is such that the vertical (up and down) length is longer than the vertical length of the elongated opening 43a, and the horizontal (left and right) length is longer than the horizontal length of the elongated opening 43a. Therefore, as shown in Fig. 8(B), even when the operation knob 4 is slid to the right as far as possible with respect to the elongated opening 43a, the operation knob 4 covers the left side of the elongated opening 43a from the front. Also, as shown in Fig. 8(C), even when the operation knob 4 is slid to the left as far as possible, the operation knob 4 covers the right side of the elongated opening 43a from the front. Therefore, the elongated opening 43a is covered by the operation knob 4 from the operator inside the vehicle, which improves the design of the cash register 1.

[0028] As an example, if the size of the operation knob 4 is 8 mm in height and 50 mm in width and the size of the elongated opening 43a is 6 mm in height and 35 mm in width, then since the sliding width of the operation knob 4 is 15 mm or less, the elongated opening 43a will be covered by the operation knob 4 even when the operation knob 4 is slid left and right. In this example, the size of the opening of the air guide passage 3a of the barrel 3 is 20 mm in height and 150 mm in width.

[0029] As shown in Fig. 5(D), when the operation knob 4 is inserted into the elongated opening 43a, the engagement claw receiver 4b at the rear end of the flange 4a protrudes rearward from the elongated opening 43a, and a joint member 45 is connected to the engagement claw receiver 4b at the rear. An operation shaft portion 46 that operates the movable louver 5 is connected to the rear of the joint member 45 (Fig. 4(D)).

[0030] As shown in Figures 6 and 9, a load-applying member 44 is built into the flange 4a, and when the flange 4a (operation knob 4) slides left and right, the load-applying member 44 abuts against the elongated opening 43a, so that the operation knob 4 slides with an appropriate operating load applied, and malfunction due to vibration, etc. can be prevented.

[0031] 6, the joint member 45 has a generally rectangular parallelepiped shape, and is provided with an engagement claw 45b extending downward from the upper side of the center in the left-right direction at the front, and abutment claws 45c are provided on the left and right sides of the engagement claw 45b. The engagement claws 45b of the joint member 45 are fitted into the engagement claw receivers 4b of the operation knob 4 from above, and the abutment claws 45c come into contact with the left and right back surfaces 4c of the engagement claw receivers 4b, so that the joint member 45 is connected to the rear of the operation knob 4. By fitting the engagement claws 45b into the engagement claw receivers 4b of the operation knob 4 from above, the joint member 45 connected to the operation knob 4 can be made compact, and space can be saved from the operation knob 4 to the operation shaft portion 46.

[0032] 5(B)-(D), support pieces 45a are provided on the left and right sides of the rear of the joint member 45, and the support pieces 45a clamp an engagement shaft 46a extending left and right from the front end of the operation shaft portion 46 so as to be rotatable in the vertical direction (FIG. 4(D)). By being clamped by the joint member 45 so as to be rotatable in the vertical direction, the engagement shaft 46a rotates up and down relative to the barrel 3 as shown in FIG. 9, and the engagement between the operation shaft portion 46 and a linkage portion 51 described later is maintained, and the movable louver 5 can be operated by the operation knob 4.

[0033] The operating knob 4 is connected to the movable louver 5 via the operating shaft portion 46, and the operator can place his / her finger on the operating knob 4 to tilt the barrel 3 up and down, and slide it left and right to tilt the movable louver 5 left and right.

[0034] The connecting frame 43 is fixed to the barrel 3, and is disposed at a position overlapping in the front-rear direction with the second rear fin 50 from the left of the movable louver 5 in the neutral state, as shown in Fig. 8(A). As a result, when the register 1 is viewed from the front, the connecting frame 43 appears to overlap with one of the rear fins 50, improving the design of the register 1.

[0035] As shown in Fig. 7, the movable louver 5 has seven vertical rear fins 50 arranged side by side at intervals, and each rear fin 50 is rotatably supported by upper and lower support shafts 50a in shaft holes 53a of bearing plates 53 (Fig. 3) arranged above and below. Also, a connecting shaft 50b protruding from one end of the rear of each rear fin 50 is connected to a connecting hole 52a of a link bar 52, so that all the rear fins 50 can change their orientation from left to right in synchronization.

[0036] The movable louver 5 has a circular linking portion 51 provided in front of the second rear fin 50 from the left, and the operating shaft portion 46 connected to the rear of the operating knob 4 engages with the linking portion 51, so that when the operating knob 4 is slid left or right, the orientation of the rear fin 50 of the movable louver 5 is adjusted left or right.

[0037] As a result, by rotating the operating knob 4 up and down, the orientation of the barrel 3 is adjusted up or down, and by sliding the operating knob 4 left or right, the orientation of the movable louver 5 is adjusted left or right via the linkage part 51.

[0038] The register 1 having the above configuration is mounted on the instrument panel or dashboard of an automobile so that the air intake 22 at the rear end of the retainer 2 is connected to a ventilation duct (not shown). Although not shown in the mounting state, the bezel 6 having the air outlet 61 of the register having the above configuration is fitted and mounted on the instrument panel or dashboard. Air sent from the ventilation duct passes through the ventilation passage 2a in the retainer 2 and the air guide passage 3a, and is blown out from the air outlet 61 into the passenger compartment of the automobile.

[0039] When the barrel 3 is in a neutral state, the airflow in the ventilation passage 2a moves straight as shown in Fig. 9(A). A connecting frame 43 equipped with an operation knob 4 is provided in a portion of the left-right direction in the air guide passage 3a of the barrel 3, and in this portion, as shown in Fig. 9(A), the presence of the operation knob 4 and the connecting frame 43 may affect the air conditioning performance. However, in most of the left-right direction in the air guide passage 3a of the barrel 3, as shown in Fig. 10, the operation knob 4 and the connecting frame 43 are not disposed in the air guide passage 3a of the barrel 3, and the effect on the air conditioning performance is reduced.

[0040] When adjusting the air blowing direction upward, as shown in Fig. 9(B), by operating the operation knob 4 upward, the barrel 3 having the blade 30 tilts upward via the connecting frame 43, and the air blowing direction is adjusted upward. When adjusting the air blowing direction downward, as shown in Fig. 9(C), by operating the operation knob 4 downward, the barrel 3 tilts downward via the connecting frame 43, and the air blowing direction is adjusted downward.

[0041] When adjusting the air blowing direction to the right, as shown in Fig. 8(B), sliding the operation knob 4 to the right causes all the rear fins 50 of the movable louvers 5 to tilt to the right via the operation shaft portion 46, the linking portion 51, and the link bar 52, and the air blowing direction is adjusted to the right. When adjusting the air blowing direction to the left, sliding the operation knob 4 to the left causes all the rear fins 50 of the movable louvers 5 to tilt to the left, and the air blowing direction is adjusted to the left. When the operation knob 4 is slid all the way to the left, the rear fins 50 overlap on the left and right, blocking the ventilation passage 2a, and the air blowing direction is shut out, as shown in Fig. 8(C).

[0042] According to the register 1 according to the embodiment of the present specification, the barrel 3 is formed of a frame body in which the air guide passage 3a is provided, and the operation knob 4 is provided on the front side of the connecting frame 43 that connects the short sides of the barrel 3 inside the frame body. Therefore, when viewed from an operator inside the vehicle cabin, the rear connecting frame 43 is hidden behind, and the operation knob 4 appears to be floating inside the frame body of the barrel 3, improving the design. In addition, only the connecting frame 43 equipped with the operation knob 4 is provided inside the air guide passage 3a of the barrel 3, so that the impact on air conditioning performance can be reduced. The register 1 of the embodiment can also be embodied in the following forms.

[0043] In the register 1 of the embodiment, the barrel 3 is formed by joining the front frame member 35 and the rear frame member 36 at the front and rear and sandwiching the connecting frame 43, which is a separate member, from above and below to form a frame body, but it is also possible to use a barrel in which the frame body forming the barrel 3 and the connecting frame 43 are integrally molded. This allows the number of parts constituting the register 1 to be reduced.

[0044] This is particularly suitable for the case of using a barrel in which the frame body and the connecting frame 43 are integrally molded, and the recesses 34 in the blade 30 that are recessed in an arc-shaped cross section can be formed as recesses 34A that are recessed in an arc-shaped cross section that forms a smooth curve, as shown in Fig. 11. This can further improve the directionality of the air blown when the barrel 3 is tilted in the short direction relative to the air outlet 61.

[0045] In the embodiment of the register 1, each part constituting the register 1, including the operation knob 4, is made of a black synthetic resin, but the operation knob 4 can be plated or painted in another color, such as silver plating. This makes the operation knob 4 look like it is floating more in the barrel frame, further improving the design.

[0046] In the register 1 of the embodiment, the connecting frame 43 of the barrel 3 is arranged so as to overlap in the front-to-rear direction with the second rear fin 50 from the left of the movable louver 5 in the neutral state, but the connecting frame 43 can be arranged at a position where it overlaps in the front-to-rear direction with any of the rear fins 50 of the movable louvers 5. For example, the connecting frame 43 (operation knob 4) can also be arranged so as to overlap in the front-to-rear direction with the fourth rear fin 50 from the left of the movable louver 5, which is the center of the register 1 in the left-to-right direction.

[0047] In the register 1 of the embodiment, one connecting frame 43 of the barrel 3 is provided at approximately the center in the left-right direction of the knob support portion 43c, but two can be provided on the left and right of the knob support portion 43c. In this case, the two connecting frames 43 can be arranged so that they overlap in the front-rear direction with the two adjacent connecting frames 43 that are lined up on the left and right of the rear fin 50 in the neutral state.
