Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a barrel-shut type register device in which a conditioned air outlet is closed by the top or bottom wall of a barrel provided with horizontal fins, and particularly relates to such a barrel-shut type register device. The present invention relates to a technique for facilitating opening and closing operations of an air outlet in a device.

(Background Art) In general, a barrel-shut type register device has a barrel equipped with a large number of horizontal fins between a top wall and a bottom wall that is rotatable around a horizontal axis in a housing that forms a vent for conditioned air. It has an arranged structure. By rotating the barrel around the horizontal axis, the air outlet is closed by the top wall or bottom wall of the barrel, and by blocking the air outlet with the top wall or bottom wall of the barrel. , to prevent conditioned air from blowing out from the outlet.

By the way, in such a barrel-shut type register device, the rotation operation of the barrel for opening and closing the air outlet is performed with fingers.
In the conventional register device, the rotation operation of the barrel when opening and closing the air outlet was performed by fingers over the entire rotation stroke. For this reason, when opening and closing the air outlet, the rotation angle (rotation stroke) of the barrel that must be rotated by fingers is large, making the operation of opening and closing the air outlet more troublesome.

In addition, in particular, in order to improve the design when the outlet is closed, if the top or bottom wall of the barrel that closes the outlet is not provided with a protrusion for rotational operation, the barrel Pressing the upper or lower end of the top wall or bottom wall with your finger will rotate the barrel from the closed position to the open position and open the air outlet. At this point, the gap between the barrel and the housing becomes so narrow that you can no longer fit your fingers in, so you have to change the position of your fingers during the rotation operation and rotate the barrel in two stages. There was a problem.

(Problem to be solved) The present invention was developed against the background of the above, and the problem to be solved is that a protrusion for rotating the barrel is provided on the top or bottom wall of the barrel. regardless of whether it is
Provides a barrel-shut type register device that makes it easy to open and close an air outlet, especially to open and close an air outlet, which allows the barrel to smoothly rotate from a closed position to an open position just by slightly rotating the barrel once with a finger. It's about doing.

(Solution Means) In order to solve this problem, in the present invention, a large number of horizontal fins are provided between the top wall and the bottom wall in the housing forming the outlet for conditioned air as described above. A barrel equipped with a barrel is arranged to be rotatable around a horizontal axis, and the air outlet is closed by the top wall or the bottom wall of the barrel by rotating the barrel around the horizontal axis. A barrel-shaft type register device configured to prevent blowing out of conditioned air from the outlet includes (a) a rotating member rotatably provided integrally with the barrel, and (b) a portion of the rotating member. (c) an engaging protrusion provided on one of the rotating member and the link member; and (c) an engaging protrusion provided on one of the rotating member and the link member, and and an engagement groove formed in the housing, and in a range where the barrel rotates between a closed position that closes the outlet of the housing and a predetermined open position that opens the outlet, the engagement protrusion and Based on the engagement with the engagement groove, the rotation member and the link member are rotated in conjunction with each other around their respective rotation axes, while the rotation angle of the barrel from the closed position is determined by the predetermined angle. an engaging means that allows the rotating member to rotate within a predetermined rotation angle range without rotation of the link member when the rotation angle is larger than that in the open position; d) A rotation range that prevents the link member from rotating beyond the rotation range that is allowed to rotate as the barrel rotates between the closed position and the predetermined open position. and (e) when the rotational position of the link member is biased in any direction from a turnover position set in the middle of the rotational range regulated by the rotational range restriction means; The link member is configured to include a turnover spring means for biasing the link member in the biased direction.

(Function) In the barrel shaft type register device having such a configuration, when the barrel is in the closed position where the top wall or the bottom wall closes the air outlet, the biasing force of the turnover spring means is rotated through the link member. As a result of the action on the moving member, the barrel is biased to its closed position by the biasing force of the turnover spring means and stably held in its closed position. The closed position of the barrel is defined by a rotation range regulating means for regulating the rotation range of the link member.

To rotate the barrel from the closed position to the open position, place your finger on the top or bottom wall of the barrel that blocks the air outlet, and rotate the barrel until the link member passes the turnover position. make it move. In this way, the barrel automatically rotates based on the biasing force of the turnover spring means until the rotation of the link member reaches the open position of the outlet defined by the rotation range regulating means. It will be done.

Therefore, if the amount of rotation of the barrel until the link member exceeds the turnover position is set small in advance, it is possible to automatically rotate the barrel to the open position by slightly rotating the barrel from the closed position. Therefore, regardless of the presence or absence of a protrusion for rotational operation, that is, even if the protrusion for rotational operation is omitted to improve the design when the air outlet is closed. The outlet can be opened with an extremely simple operation of pressing the barrel once with a finger.

Note that when the link member has been rotated beyond the turnover position to a position where further rotation is prevented by the rotation range regulating means, the rotating member can be rotated without any rotation of the link member. By rotating the barrel around the horizontal axis, the vertical blowing direction of the conditioned air can be freely adjusted within a preset range.

(Example) In order to clarify the present invention more specifically, an example of the application of the present invention to a barrel-shut type register device for an automobile will be described in detail below with reference to the drawings.

First, in FIGS. 1 to 3, reference numeral 2 denotes a bezel as a housing, which has a cylindrical structure with a longitudinal rectangular end surface long in the horizontal direction, and one opening of which is used to blow out conditioned air. It is said to be Exit 4. Further, in those figures, 6 is a barrel having a longitudinal rectangular cylindrical shape, which is one size smaller than the bezel 2, and as shown in FIG. is the side wall 10,1 of the bezel 2
Rotation shafts 12, 12, which serve as horizontal shafts, are rotatably disposed through the shafts 0 and 12, respectively, and are connected to each other in a non-rotatable manner. As a result, the barrel 6 can be rotated integrally with the rotating shafts 12, 12 within the bezel 2 around the axes of the rotating shafts 12, 12. .

Here, when the conditioned air is being blown out from the outlet 4 of the bezel 2, there is an opening on the side where the conditioned air is blown out between the top wall 14 of the barrel 6, which is positioned on the upper side and the bottom side, respectively, and the bottom wall (not shown). A plurality of lateral fins 18 are provided parallel to the top wall 14 and the bottom wall. As a result, when the air outlet 4 is in the open state, by rotating the barrel 6 around the rotation shafts 12, the blowing direction of the conditioned air blown out from the bezel 2 can be adjusted in the vertical direction. It's getting old.

Moreover, between the upper wall 14 and the bottom wall of the barrel 6,
Like a normal register device, a plurality of vertical blades 26 are rotatably supported on the top wall 14 and the bottom wall by upper and lower support shafts (not shown), and are connected to each other by connecting members. . By rotating the vertical blades 26 about their respective spindles when the air outlet 4 is open, the blowing direction of the conditioned air blown from the bezel 2 can be adjusted in the horizontal direction. There is.

Here, as clearly shown in FIGS. 1 and 3, the rotation of the barrel 6 about the rotation axes 12, 12 causes the bezel 2 to harmonize with the upper wall 14 of the barrel 6. The air outlet 4 can be blocked, and by blocking the air outlet 4 of the bezel 2 with the upper wall 14 of the barrel 6, blowing out of conditioned air from the outlet 4 of the bezel 2 is prevented. I'm starting to be able to do it. In other words, it is now equipped with an air-shut function.

Note that the upper and lower ends of the air outlet 4 of the bezel 2 are defined by inward flange parts 30 and 32, respectively, and these inward flange parts 30,
Seals 34 and 36 made of foamed urethane or the like are affixed to the back side of the holder 32, respectively. and a bezel 2 formed by the upper wall 14 of the barrel 6.
When the air outlet 4 is closed, the end of the barrel 6 is pressed directly against the upper seal 34, while the barrel 6 is extended from the upper wall 14 against the lower seal 36. The uppermost horizontal fin 18 is pressed against its tip.

By the way, one end of the rotating shaft 12 that rotatably supports the barrel 6 with respect to the bezel 2 protrudes outward from the side wall 10 of the bezel 2, as shown in FIG. The protruding end thereof is fixedly attached to the base end of a longitudinal rotating arm 38 as a rotating member. As a result, the rotating arm 38 and the barrel 6 can be integrally rotated about the axes of the rotating shafts 12, 12.

A boss 40 is provided on the outer surface of the side wall 10 of the bezel 2, on which the rotating arm 38 is disposed, at a predetermined distance apart from the location where the rotating shaft 12 is disposed.
Further, a boss 42 is provided upright at a predetermined distance from the location where the boss 40 and rotation shaft 12 are provided. A link member 44 is rotatably attached to the boss 40 with a screw 41, and the link member 44 is provided at one end.
4, and the other end thereof is engaged with the boss 42 with a screw 43, and a turnover spring 46 is disposed.

Here, the link member 44 has a structure in which two long and short arms 48, 50 are connected at a substantially right angle, and is rotatably attached to the boss 40 at the connecting portion of the arms 48, 50. . and,
In the attached state, the arm 48 is superimposed on the outer surface of the rotating arm 38, and the arm 48
Rotating arm 3 at engagement hole 52 formed in 8
It is engaged with an engagement pin 54 that is provided upright on the outer surface of the tip portion of the holder 8 .

More specifically, the engagement hole 52 formed in the arm 48 of the link member 44 is connected to the arm 48 of the link member 44.
It is formed to extend in the longitudinal direction. Based on the fact that the engagement pin 54 moves in the engagement hole 52 in the longitudinal direction of the arm 48,
Rotation of the rotation arm 38 and, by extension, rotation of the barrel 6 is allowed.

Here, the proximal end portion of the arm 48 of the engagement hole 52 is a straight portion 56 of a predetermined length, and the distal end portion of the arm 48 is an arcuate portion 58 of a predetermined length. As a result, in the range of rotation of the rotation arm 38 in which the engagement pin 54 moves within the linear portion 56 of the engagement hole 52, the link member 44 moves around the boss 40 to engage the rotation arm 38. In addition, in the rotation range of the rotation arm 38 in which the engagement pin 54 moves within the arcuate portion 58 of the engagement hole 52, the rotation of the link member 44 is prevented. The rotary arm 38 is configured to be able to rotate independently without any movement.

Here, the straight portion 5 of the engagement hole 52 is
The rotation range of the barrel 6 in which the engagement pin 54 moves within the upper wall 14 of the barrel 6 is
the closed position where the conditioned air is closed, and the open position where the blowing direction of conditioned air is the lowest point (hereinafter simply referred to as the open position).
In order to correspond to the rotation range of the barrel 6 between
The linear portion 56 of the engagement hole 52 is formed, and the rotation range of the barrel 6 in which the engagement pin 54 moves within the arcuate portion 58 of the engagement hole 52 is vertical in the blowing direction of conditioned air. The arcuate portion 58 of the engagement hole 52 is formed to correspond to the rotation range of the barrel 6 that is adjusted in the direction.

In addition, as shown in FIG. 3, the side wall 10 of the bezel 2 has a rotation position that is higher than the rotation position when the barrel 6 is rotated to the closed position that closes the air outlet 4 of the bezel 2. In order to prevent the link member 44 from rotating, a stopper pin 60 that comes into contact with the arm 48 of the link member 44 to prevent further rotation of the link member 44 is provided and is shown in FIG. , the link member 44 is moved beyond the rotational position when the barrel 6 is rotated to the open position.
The arm 4 of the link member 44 is
A stopper pin 62 that comes into contact with 8 and prevents further rotation of the link member 44 is provided upright, and the rotation range of the link member 44 is regulated by these stopper pins 60 and 62. .
That is, here, those stopper pins 60,
62 constitutes a rotation range regulating means for regulating the rotation range of the link member 44.

Further, here, as is clear from FIGS. 1 and 3, the tip of the arm 48 of the link member 44 has a curved shape corresponding to the shape of the arcuate portion 58 of the engagement hole 52.

On the other hand, a locking protrusion 64 is formed on the other arm 50 of the link member 44 at its tip. The turnover spring 46 is disposed with both ends thereof being locked by the locking protrusion 64 and the boss 42, and here, as shown in FIG. When the link member 44 is rotated from the closed position toward the open position by a preset rotation angle and reaches the middle part of the rotation range defined by the stopper pins 60 and 62, the turnover spring 46 The urging force is prevented from acting on the link member 44 as a rotational force.

In other words, this rotational position is the turnover position of the turnover spring 46, and the stopper pin 6 is lower than the turnover position.
At the rotational position of the link member 44 that has moved to the 0 side, a rotational force is applied to the link member 44 in the direction of rotating the link member 44 toward the stopper pin 60 based on the biasing force of the turnover spring 46. and the stopper pin 6 is lower than the turnover position.
At the rotational position of the link member 44 moved to the second side, a rotational force is applied to the link member 44 in the direction of rotating the link member 44 toward the stopper pin 62 based on the biasing force of the turnover spring 46. It's getting old.

In the register device having such a configuration, the upper wall 14
When the barrel 6 is rotated to the closed position where it closes the air outlet 4 of the bezel 2, the link member 44 is rotated based on the biasing force of the turnover spring 46.
is biased to the abutting position against the stopper pin 60, so that the barrel 6 is biased to its closed position by the biasing force acting on the pivot arm 38 from the link member 44 via the engagement pin 54. Therefore, even if vibrations or the like are input, the barrel 6 is stably held in the closed position, and the air-shut condition of the register device is maintained well.

On the other hand, in order to rotate the barrel 6 from the closed position to the open position and blow out conditioned air etc. from the outlet 4 of the bezel 2, as shown in FIG. The upper wall 1 of the barrel 6 that closes the
Press the upper end (rear end) of link member 4 with your finger.
The barrel 6 is rotated until the position 4 exceeds the turnover position.

If the barrel 6 is rotated until the link member 44 exceeds the turnover position, the turnover spring 4
The barrel 6 is automatically rotated to the open position by the biasing force of the register device 6. Therefore, compared to a conventional register device in which the barrel 6 is rotated from the closed position to the open position entirely by fingers. , barrel 6 by finger
The amount of rotation is reduced, making it easier to open the air outlet 4.

Moreover, the register device of this embodiment has a bezel 2
Although the upper wall 14 that closes the air outlet 4 is not specially provided with a protrusion for rotating the barrel 6, the design can be improved when the air outlet 4 is closed. As described above, by slightly rotating the barrel 6 with your fingers, the barrel 6 can be rotated from the closed position to the open position without changing the pressing position of your fingers on the barrel 6. Compared to this type of conventional register device, opening the air outlet becomes much easier.

Note that when the barrel 6 is rotated to the open position, the link member 44 is held in the abutting position against the stopper pin 62 by the biasing force of the turnover spring 46; Since the engaging pin 54 is able to move within the engaging hole 52 (arc shaped portion 58) without rotation of the rotating arm 3.
8, furthermore, the barrel 6 can be rotated independently, so the barrel 6 can be rotated by the rotation axis 12,
By independently rotating it around 12 degrees, the blowing direction of conditioned air can be freely adjusted in the vertical direction.

As explained above, the register device of the present embodiment has a design that can be improved when the air outlet 4 is closed without providing a protrusion for rotation operation on the upper wall 14 of the barrel 6 that closes the air outlet 4 of the bezel 2. Although the system is designed to improve performance, the barrel 6 can be easily rotated from the closed position to the open position of the air outlet 4 by simply pressing the finger once and slightly rotating the barrel 6. In addition, when the barrel 6 is rotated to the closed position where the upper wall 14 closes the air outlet of the bezel 2, the barrel 6 is stabilized in the closed position. It has the advantage of being able to maintain

Note that, as is clear from the above description, in this embodiment, the engagement pin 5 erected on the rotating arm 38 is
4 constitutes an engagement protrusion of the engagement means, and
The engagement hole 52 of the link member 44 with which the engagement pin 54 is engaged constitutes an engagement groove of the engagement means.

One embodiment of the present invention has been described in detail above, but
This is a literal example, and it goes without saying that the present invention should not be construed as being limited to this specific example.

For example, in the embodiment, the air outlet 4 of the bezel 2
The rotation of the link member 44 in the direction of closing the bezel 2 was defined by the contact of the link member 44 with the engagement pin 60 erected on the side wall 10 of the bezel 2. The regulating means for regulating the rotation of the link member 44 does not necessarily have to directly prevent the rotation of the link member 44, but may prevent the rotation of the barrel 6, the rotation arm 38, etc. Therefore, the rotation of the link member 44 may be indirectly prevented.

Further, in the embodiment, the rotation of the link member 44 in the direction of opening the air outlet 4 of the bezel 2 causes the link member 44 to come into contact with the engagement pin 62 erected on the side wall 10 of the bezel 2. However, such an engaging pin 62 does not necessarily need to be provided. Even if such an engagement pin 62 is not provided, the rotation of the link member 44 in the above direction is inevitably prevented based on the engagement of the engagement pin 54 with the circular arc portion 58 of the engagement hole 52. This is because that. In this case, the engagement means made up of the engagement hole 52 and the engagement pin 54 also serves as part of the rotation range regulating means for regulating the rotation range of the link member 44.

Furthermore, in the embodiment described above, the engagement hole 52 as an engagement groove is provided on the link member 44 side, while the engagement pin 54 as an engagement protrusion is provided on the rotation arm 38 side as a rotation member. However, it is also possible to configure the engagement means by providing the engagement groove on the rotating member side and the engagement protrusion on the link member side.

Further, in the above embodiment, the rotating member (rotating arm), the link member, the turnover spring means, etc. were provided on the outside of the side wall of the housing (bezel). It is also possible to configure a register device having a function similar to that of the above embodiment by providing it in the space between the register device and the register device. In this case, the side wall 8 of the barrel 6 can be used as the rotating member.

Further, in the above embodiment, an example was described in which the present invention was applied to a register device for an automobile in which the outlet for conditioned air was blocked by the upper wall of the barrel.
It is also possible to apply the present invention to a register device in which the outlet for conditioned air is closed by the bottom wall of a barrel, and it is also possible to apply the present invention to register devices other than those for automobiles.

Although it is omitted to list specific examples one by one, it goes without saying that the present invention can be implemented with various changes, modifications, improvements, etc. within the scope of the invention.

(Effect of the invention) As is clear from the above explanation, according to the barrel-shaft type register device according to the invention, the barrel can be rotated slightly by pushing with a finger the top wall or bottom wall of the barrel that blocks the conditioned air outlet. The barrel can be automatically rotated from the closed position that closes the air outlet to the open position by simply moving the air outlet, which has the advantage that opening the air outlet is extremely easy. is in the closed position,
Since the barrel is biased to its closed position by the biasing force of the turnover spring means, there is an advantage that the air shaft condition is stably maintained.
