Description

[Technical Field]

[0001] The present invention relates to a register device for blowing air from an air conditioner or from outside the vehicle into a vehicle compartment. [Background technology]

[0002] Patent Document 1 below discloses a register device installed on a vehicle instrument panel. This register device includes a register body having an air passage, multiple upstream fins arranged on the upstream side of the air passage, a single downstream fin arranged on the downstream side of the air passage, and an operation knob for operating the upstream fin.

[0003] The ventilation passage of the register body is shaped so that the horizontal dimension is larger than the vertical dimension.

The downstream fin has five flat plate sections extending left and right inside it, and these flat plate sections are arranged parallel to each other in the vertical direction.

[0004] The upstream fins are supported on the upper and lower walls of the downstream fin so as to be rotatable about respective rotation axes extending in the vertical direction, and are arranged side by side in the left-right direction. The operating knob is supported on the flat plate portion of the downstream fin and is slid left and right, thereby rotating the upstream fins. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 61-128058 Summary of the Invention [Problem to be solved by the invention]

[0006] In the cash register of Patent Document 1, the operating knob straddles the flat plate portion in the vertical middle of the second fin and is inserted between the flat plate portions above and below it. This increases the vertical size of the operating knob, which not only impairs the design but also hinders the formation of a horizontally elongated, flattened ventilation passage in the cash register body. [Means for solving the problem]

[0007] The present invention has been made to solve at least one of the above problems, and one aspect of the present invention provides a vehicle register device comprising a register body, a plurality of first fins, a single second fin, and an operating knob. The register body has an air passage having a dimension in a second direction perpendicular to the first direction that is larger than a dimension in the first direction. The first fins are each supported on the register body so as to be rotatable about a first rotation axis extending in the first direction, and are arranged side by side in the second direction. The second fin is disposed closer to the air outlet of the ventilation passage than the first fin, is supported on the register body so as to be rotatable about a second rotation axis extending in the second direction, and extends in the second direction. The operation knob is supported on the second fin so as to be slidable in the second direction, and rotates the first fin as it slides. The second fin has a pair of flat plate portions extending parallel to each other in the second direction, and the operating knob is inserted between the pair of flat plate portions so as to fit between the pair of flat plate portions in the first direction.

[0008] According to the above configuration, the pair of flat plate portions of the single second fin look like two fins, and the operation knob is inserted between the pair of flat plate portions and fits between the pair of flat plate portions in the first direction, improving design. Because the operation knob is formed flat so that it fits between the pair of flat plate portions in the first direction, the ventilation passage of the register body can be formed into a flat shape whose dimension in the second direction is larger than that in the first direction.

[0009] Preferably, an air passage is formed between the pair of flat plate portions, and the operation knob can form the air passage on both sides, one side, or the other side in the second direction of the operation knob by sliding.

[0010] Preferably, an air inlet extending in the second direction is formed upstream between the pair of flat plate portions of the second fin, corresponding to the sliding area of ​​the operating knob, and the operating knob can be slid to open both ends, one end or the other end of the air inlet in the second direction to form the air passage.

[0011] Preferably, the second fin has a slide support portion provided on one of the pair of flat plate portions for slidably supporting the operation knob, and the slide support portion has a dimension in the second direction smaller than that of the operation knob. [Effects of the Invention]

[0012] According to the present invention, the design of the register device can be improved and the ventilation passage of the register body can be formed in a flat shape. [Brief explanation of the drawings]

[0014] An embodiment of the present invention will be described below with reference to Figures 1 to 7. The cash register device shown in Figures 1 and 2 is installed on the instrument panel (interior panel) of a vehicle, and blows out temperature-controlled air from an air conditioner and air from outside the vehicle into the passenger compartment. In the following description of the cash register device, the front, rear, left, and right of the cash register device are defined based on the front, rear, left, and right of the vehicle.

[0015] The register device 1 includes a register body 10, a plurality of upstream fins (first fins) 20, a single downstream fin (second fin) 30, and an operation knob 40. As shown in Figures 1, 3, and 4, the register body 10 has a cylindrical main portion 11 extending in the front-to-rear direction, a bracket 12 for supporting the upstream fin 20, and two brackets 13, 13 for supporting the downstream fin 30.

[0016] The register body 10 has an internal ventilation passage 14. The ventilation passage 14 has a flat shape in which the dimension in the up-down direction (second direction) is larger than the dimension in the left-right direction (first direction), and the register body 10 has a horizontal trapezoidal shape when viewed from the front. The upstream end of the ventilation passage 14 serves as an air inlet 15, which is connected to an air conditioning unit or a duct 2 extending from the outside of the vehicle body, and the downstream end serves as an air outlet 16, which is connected to an opening 3a formed in the instrument panel 3.

[0017] The bracket 12 is annular and has flanges 12a on the left and right sides of the air outlet 16, and these flanges 12a are engaged with the end face of the main part 11 on the air outlet 16 side. Left and right wall parts 12b are connected to the flanges 12a, respectively, and extend to the middle of the ventilation channel 14 toward the air inlet 15. The brackets 13, 13 are respectively fastened to the upper and lower parts of the main part 11 on the air outlet 16 side. The bracket 12 and the brackets 13, 13 form a part of the air outlet 16.

[0018] 1 and 3, five upstream fins 20 are provided in this embodiment, and are arranged in the ventilation passage 14 approximately midway between the air inlet 15 and the outlet 16. Each upstream fin 20 is plate-shaped with its plate surface facing up and down, and is arranged spaced apart from each other in the vertical direction. As shown in FIG. 4, each upstream fin 20 is supported by support shafts 21 protruding on the left and right sides thereof on the left and right wall portions 12b of the bracket 12 of the register main body 10, and is rotatable around a rotation axis L1 (first rotation axis) passing through the support shafts 21.

[0019] 1, each upstream fin 20 has a connecting pin 22 parallel to the rotation axis L1 behind the left support shaft 21. A connecting link 23 extending in the vertical direction is rotatably connected to each connecting pin 22. This allows all the other upstream fins 20 to tilt in synchronization with the tilting of one upstream fin 20.

[0020] 1 and 3, one of the five upstream fins 20 (the second upstream fin 20 from the bottom in this embodiment) has a notched end on the air outlet 13 side and a transmission shaft 24 extending in the left-right direction. The transmission shaft 24 is connected to an operation knob 40, as will be described later.

[0021] The downstream fin 30 is disposed closer to the outlet 16 side of the upstream fin 20 in the air passage 14, and has a flat, hollow shape. As shown in Figures 1, 6 and 7, the downstream fin 30 has a pair of flat plate portions 31, 32 that extend parallel to each other in the vertical direction, with the plate surfaces of the flat plate portions 31, 32 facing left and right.

[0022] The pair of flat plate portions 31, 32 are connected at their upper and lower parts by connecting plate portions 33, 34. An air inlet 35 is formed in the vertical center of the upstream side of the downstream fin 30, extending vertically and sandwiched between the flat plate portions 31, 32. The upper and lower parts of the air inlet 35 are closed, and the air inlet 35 is formed to correspond to the sliding area of ​​an operation knob 40, which will be described later. An air outlet 36 is formed downstream of the downstream fin 30 by the flat plate portions 31, 32 and the connecting plate portions 33, 34. Therefore, an air passage is formed between the pair of flat plate portions 31, 32 within the downstream fin 30.

[0023] Support shafts 37, 37 protrude upward and downward from the connecting plate portions 33, 34, respectively, and as shown in Figure 3, the downstream fin 30 is supported on the upper and lower brackets 13, 13 of the register main body 10 by the upper and lower support shafts 37, 37, and can rotate around a rotation axis L2 (second rotation axis) passing through the support shafts 37, 37.

[0024] The upper connecting plate portion 33 has an engagement pin 38 parallel to the rotation axis L2 at the rear side of the support shaft 37. The engagement pin 38 slidably engages with a restriction groove 13a formed in the upper bracket 13. The restriction groove 13a extends in an arc centered on the rotation axis L2, and the rotation range of the downstream fin 30 is restricted by the restriction groove 13a.

[0025] As shown in FIG. 7, one flat plate portion 31 of the downstream fin 30 is provided with a slide support portion 50 at a position corresponding to the air inlet 35. The slide support portion 50 slidably supports the operation knob 40 (described later), and as shown in Fig. 5(B), has a base portion 51, a slide support piece 52, and a marker piece 53. The base portion 51 is formed in a flat plate shape extending from one flat plate portion 31 toward the other flat plate portion 32. The slide support piece 52 extends in a cantilevered manner from the tip of the base portion 51 toward the air inlet 35. The marker piece 53 extends in a cantilevered manner from the tip of the base portion 51 toward the air outlet 36.

[0026] The operating knob 40 is used to rotate the upstream fin 20 and the downstream fin 30, has a flat shape, is supported by the slide support portion 50 of the downstream fin 30, and has a knob body 41 and a supported member 42, as shown in Figure 3.

[0027] The knob body 41 has a shape in which the width narrows from one end on the supported member 42 side to the other end, and the width of the knob body 41 is formed to be larger than the vertical length of the slide support portion 50 of the downstream fin 30. The thickness of the knob body 41 is formed to be approximately the same as the distance between the pair of flat plate portions 31, 32 of the downstream fin 30, as shown in FIG.

[0028] As shown in Figures 5(B) and 6, the knob body 41 is formed in a generally L-shaped cross section and has a bottom wall 41a at its tip end, with long walls 41b and short walls 41c extending from the left and right ends of the bottom wall 41a. As shown in Figure 6, restriction walls 41d, 41d are provided to close the upper ends and lower ends of the long wall 41b and short wall 41c, and each restriction wall 41d extends to the tip of the long wall 41b. A locking hole 41e is formed at the tip of each restriction wall 41d and is used to attach the supported member 42.

[0029] Each restriction wall 41d has an abutment portion 41f provided closer to the bottom wall 41a than the locking hole 41e. As will be described later, the base portion 51 of the slide support portion 50 abuts against the abutment portion 41f, thereby restricting the sliding range of the operation knob 40. A notch 41g is formed in the center of the tip of the long wall 41b in the vertical direction.

[0030] When the operation knob 40 is configured by attaching the supported member 42 to one end of the knob body 41 , the supported member 42 is slidably supported by the slide support portion 50 of the downstream fin 30 . 6, the supported member 42 is formed to be elongated in the vertical direction and has hook-shaped locking protrusions 42a, 42a at its upper and lower ends. These locking protrusions 42a, 42a are locked into locking holes 41e, 41e of the knob main body 41, and the supported member 42 is attached to the knob main body 41.

[0031] The thickness (length in the left-right direction) of the supported member 42 is also formed to be approximately the same as the distance between the pair of flat plate portions 31, 32, similar to the knob body 41. Therefore, the operating knob 40 is accommodated between the flat plate portions 31, 32 in the left-right direction.

[0032] 5(B) and 6, the supported member 42 has a slide fitting portion 42b with a generally U-shaped cross section on the downstream side of the middle portion in the vertical direction. A press-fitting protrusion 42c is provided on at least one opposing surface of the slide fitting portion 42b.

[0033] Here, the assembly of the knob body 41 and the supported member 42 to the downstream fin 30 will be described. To support the operating knob 40 on the downstream fin 30, the supported member 42 is attached to the knob body 41 as follows: The knob body 41 is brought close from the marker piece 53 side so that the slide support portion 50 is sandwiched between them, and the supported member 42 is brought close from the slide support piece 52 side, and the notch 41g of the knob body 41 and the slide fitting portion 42b of the supported member 42 are aligned in position.

[0034] 5(B), the short wall 41c of the knob body 41 is inserted between one flat plate portion 31 and the marker piece 53, and the long wall 41b is inserted between the other flat plate portion 32 and the marker piece 53. At this time, the short wall 41c and the long wall 41b are in contact with the flat plate portions 31 and 32, respectively.

[0035] The tip of the long wall 41b is located between the slide support piece 52 and the flat plate portion 32, and the tip of the long wall 41b and the slide support piece 52 are press-fit into the slide fitting portion 42b. In addition, the locking protrusions 42a, 42a of the supported member 42 are locked into the locking holes 41e, 41e of the knob body 41. In this way, the operation knob 40 supported by the slide support piece 52 is formed.

[0036] The tip of the long wall 41b and the slide fitting portion 42 are able to slide up and down while being in pressure contact with the slide support piece 52, and thus the operation knob 40 is able to slide up and down relative to the downstream fin 30. The sliding range of the operation knob 40 is restricted by the vertical end faces of the base portion 51 abutting against the abutment portions 41f of the upper and lower restriction walls 41d of the knob body 41, as shown in FIG.

[0037] The operation knob 40 is provided with a fork portion 60 as a means for interlocking with the upstream fin 20 . The fork portion 60 extends upstream from the supported member 42 of the operation knob 40, and the base end of the fork portion 43 is attached so as to be sandwiched between two mounting portions 42d, 42d provided spaced apart in the vertical direction on the upstream side of the supported member 42. Each mounting portion 42d has a bearing shape, and the base end of the fork portion 60 is pivotally supported by the mounting portions 42d, 42d. This allows the fork portion to tilt left and right.

[0038] The tip of the fork portion 60 is bifurcated and has a slit 61 extending in the front-rear direction. The transmission shaft portion 24 of the upstream fin 20 is inserted into this slit 61 so as to be rotatable and movable.

[0039] Therefore, when the operation knob 40 is slid up and down along the flat plate portions 31, 32 of the downstream fin 30, the transmission shaft portion 24 moves up and down, and accordingly, the upstream fin 20 having the transmission shaft portion 24 rotates about the rotation axis L1, and further, all the other fins 20 rotate via the connecting link 23. As a result, the air outlet direction is adjusted up and down. When the operation knob 40 is moved left and right, the downstream fin 30 rotates about the rotation axis L2, and the air outlet direction is adjusted left and right.

[0040] The operation of the register device 1 will now be described. 1 and 3, the operation knob 40 is in the reference position, and the upstream fin 20 is approximately horizontal. At this time, the operation knob 40 opens the upper end of the air inlet 35 of the downstream fin 30, and an air passage is formed above the operation knob 40.

[0041] When the operation knob 40 is slid upward from the reference position, the upstream fins 20 face upward, the upper and lower ends of the air inlet 35 are opened, and air passages are formed above and below the operation knob 40. When the operation knob 40 is slid further upward, the base portion 51 and the abutment portion 41f of the lower restriction wall 41d come into contact, restricting the upward sliding, closing the upper end of the air inlet 35, and forming an air passage below the operation knob 40.

[0042] When the operation knob 40 is slid downward from the reference position, the upstream fins 20 face downward and the upper end of the air inlet 35 opens more. When the operation knob 40 is slid further downward, the base portion 51 comes into contact with the abutment portion 41f of the upper restriction wall 41d, restricting the downward sliding. At this time, the upstream fins 20 close the ventilation passage 14, as shown in FIG. 2.

[0043] According to the above embodiment, the pair of flat plate portions 31, 32 of the downstream fin 30 look like two fins, and the operation knob 40 is inserted between the flat plate portions 31, 32 and fits between the flat plate portions 31, 32 in the left-right direction, improving the design. Furthermore, since the operation knob 40 is formed flat so as to fit between the flat plate portions 31, 32 in the left-right direction, the ventilation passage 14 can be flattened in the left-right direction.

[0044] The present invention is not limited to the above-described embodiment, and can be modified as appropriate within the scope of the invention. In the above embodiment, the left-right direction and the up-down direction are defined as the first direction and the second direction, respectively. However, the up-down direction may be defined as the first direction and the left-right direction may be defined as the second direction. [Industrial Applicability]

[0045] The present invention can be applied to a register device for blowing air from an air conditioner or the outside of a vehicle into a vehicle compartment. [Explanation of symbols]
