The present invention relates to an air distributing system. More particularly, the present invention relates to an air-vent for distributing air in an interior of a vehicle.
Air-vents inside a vehicle are known for guiding and distributing air inside the vehicle. Generally, air-vents are provided with vanes for directing air and for shutting off the vent portion. These vanes facilitate in directing and deflecting the air according to the preference of the occupants inside the vehicle. These vanes are controlled and operated using a thumb wheel which is arranged exterior to the air-vents. The thumb wheel may be operated in two direction which allows the vanes to deflect the flow of air inside the air-vent. The vanes used may be flexible and may deflect the direction of the air according to the use of thumbwheel.
Further, due to space constraint in the interior panel of the vehicle, the size of the air-vent is reduced without reducing the efficiency. The reduction in size increases the complexity in the air-vent assembly as vanes are organized and assembled inside the air-vent. Also, in certain assembly, the air-vents may be covered by an aesthetic grille. The grille may affect the direction of the air flow from the vent which reduces the effective utilization of the air-vents.
Therefore, there is a need to provide an air-vent for a vehicle interior, which overcomes few or all of the drawbacks of the existing air-vents.
An object of the present invention is to provide an air-vent for distributing air in an interior of a vehicle.
Another object of the present invention is to provide an air-vent for distributing air in an interior of a vehicle, which occupies less space for assembling the air-vent assembly.
Yet another object of the present invention is to provide an air-vent for distributing air in an interior of a vehicle, which effectively utilizes the space for operation.
One more object of the present invention is to provide an air-vent for distributing air in an interior of a vehicle, which has a lesser number of constructional elements thereby making it economical.
A further object of the present invention is to provide an air-vent for distributing air in an interior of a vehicle, which is aesthetically pleasing and is robust in construction.
According to the present invention, an air-vent for distributing air in a vehicle interior is provided. The air-vent facilitates in providing proper ventilation inside the vehicle interior. In at least some embodiments, the air-vent is provided with at least one vane arranged inside the housing for opening and closing an air channel of the air-vent. In a particular embodiment, two vanes are provided which are movable between an opening position and a closing position. The vanes may be operably connected to a thumb wheel provided on the periphery of the air-vent or on an interior panel of the vehicle such that the thumbwheel may be operated by an occupant inside the vehicle.
Further, the air-vent is provided with at least a guiding member slidably configured over a housing of the air-vent and moves in and out of the housing for directing air from the air-vent into the vehicle interior. The guiding members moves in the housing means that the guiding members are moving into the air channel, specifically moving into an air out flow opening of the air vent for directing the air into the vehicle interior. The guiding members moves out of the housing means that the guiding members are moving out of the air channel of the air vent, specifically moving outside of the air out flow opening in a non-air directing position. In the preferred embodiment two guiding members such as a first guiding member and a second guiding member are shown. Specifically, the first guiding member is configured on a top portion of the housing of the air-vent and the second guiding member is configured on a bottom portion of the housing of the air-vent. The air-vent is further provided with two guide elements and respective guide openings on the top portion and the bottom portion of the housing respectively.
The guiding members slide through the guide openings to configure a position to deflect or direct the air from the air-vent. The first guiding member slides towards the bottom portion of the housing and the second guiding member slides towards the upper portion of the housing. When the first guiding member is extended or slides into the housing of the air vent through the guide opening, air from the air-vent is directed downwards into the vehicle interior. When the second guiding member is extended or slides into the housing of the air vent through the guide opening, air from the air-vent is directed upwards into the vehicle interior. When the first guiding member is extended or slides into the housing the second guiding member may retract or slide backward over the bottom portion of the housing of the air vent. Similarly, when the second guiding member is extended or slides into the housing, the first guiding member may retract or slide backward out of the housing. There may be an intermediate position where both the guide members are in non-air directing position.
Further, each of the guiding members is operably connected to an operating wheel. The operating wheel may be arranged on an instrument panel or on an outer portion of the housing of the air-vent for operating the guiding members. The movement of the guiding members are facilitated by an operating mechanism arranged exterior to the housing of the air-vent. The present embodiment is provided with two operating mechanisms like a first operating mechanism and a second operating mechanism configured on respective sides of the air-vent. Alternatively, both the guiding member's i.e. first guiding member and second guiding member can be connected to a respective operating wheel. Thus, the in and out movement of the guiding member can be actuated individually without interfering each other. Further user can also manually extent or slide the guiding members in and out of the housing of the air vent manually without any operating wheel simply by using his/her hand.
In an embodiment, the first operating mechanism includes a gear arrangement, a first transmission arrangement and a second transmission arrangement. Similarly, the second operating mechanism also includes a gear arrangement, a first transmission arrangement and a second transmission arrangement. The first operating mechanism and the second operating mechanism are commonly connected by a first shaft and a second shaft. The operating wheel is connected only to the first operating mechanism. Upon operating the first operating mechanism, the second operating mechanism is simultaneously operated through the first shaft and the second shaft.
The operating wheel may be adapted to connect with the gear arrangement of the first operating mechanism. The operating wheel has an extended portion which is preferably having a bevel gear structure configured at a distal end of the operating wheel. The bevel gear structure positively connects with a gear arrangement. The gear arrangement is preferably a bevel gear which engages with the bevel gear structure of the operating wheel and rotates with respect to the movement of the operating wheel.
The first transmission arrangement is linked with the gear arrangement for transmitting the rotary motion of the gear arrangement to the second transmission arrangement. The first transmission arrangement is a belt and pulley arrangement which is connected to the first shaft and the gear arrangement. The second transmission arrangement is also a belt and pulley arrangement which is connected between the first shaft and the second shaft. The first transmission arrangement transmits the rotary motion of the gear arrangement to the second transmission arrangement by rotating the first shaft. As the first shaft rotates, the second transmission arrangement transmits the rotary motion to the second shaft. The first shaft and the second shaft are arranged horizontally and in parallel above and below the housing of the air-vent respectively. Upon operating the first operating mechanism, the second operating mechanism is simultaneously operated through the first shaft and the second shaft.
In the present embodiment, the first guiding member and the second guiding member are wound on the first shaft and the second shaft respectively. The guiding members slide towards or away from the air-vent upon rotating the respective shafts.
In another embodiment, the air-vent is provided with a first operating mechanism and a second operating mechanism. The first operating mechanism includes a gear, a first rack and a second rack. Similarly, the second operating mechanism also includes a gear, a first rack and a second rack. The gear is connected with an operating wheel by a first link. The rotary movement of the operating wheel is transmitted to the gear by the first link. Further, the first rack is arranged in contact with the gear and the first guiding member. The first rack reciprocates upon rotating the gear and moves translationally to slide the first guiding member to extend or retract through the guide openings.
Similarly, the second rack is arranged in contact with the gear and the second guiding member. The second rack reciprocates upon rotating the gear and moves translationally to slide the second guiding member to extend or retract towards or away from the air-vent. The first guiding member and the second guiding member move in the opposite direction. The gear is further connected to a shaft by a second link. Specifically, the second link is connected to a disc, which is connected to the shaft. The rotation of the gear moves the second link which rotates the disc thereby the shaft. The second operating mechanism is connected on the opposite end of the shaft. Upon rotation of the shaft, the second operating mechanism is operated in the respective direction to move the first guiding member and the second guiding member towards or away from the air-vent.

The present embodiment is provided with two operating mechanisms like a first operating mechanism 140 and a second operating mechanism (not shown) configured on respective sides of the air-vent 100 (refer
The operating mechanisms 140 are capable of moving in a first operating direction and a second operating direction upon operating the operating wheel 130 in a first direction and a second direction respectively. In the first operating direction, the first guiding member 110a is extended towards the air-vent 100 for directing the air from the air-vent 100. During first operating direction, the second guiding member 110b is retracted from the air-vent 100. Similarly, in the second operating direction, the operating mechanism 140 moves in the second operating direction to retract the first guiding member 110a from the air-vent and extend the second guiding member 110b towards the air-vent 100.
In an alternate embodiment (not shown), both the guiding member's 110a, 110b i.e. the first guiding member 110a and the second guiding member 110b can be connected to a respective operating wheel. Thus, the in and out movement of the guiding members 110a, 110b can be actuated individually without interfering each other. Further user can also manually extent or slide the guiding members 110a, 110b in and out of the housing of the air vent 100 manually without using the operating wheel.
In an embodiment as shown in
The operating wheel 130 is adapted to connect with the gear arrangement 142 of the first operating mechanism 140. The operating wheel 130 is having an extended portion 130a which is preferably having a bevel gear structure configured at a distal end of the operating wheel 130. The bevel gear structure positively connects with gear arrangement 142. The gear arrangement 142 is preferably a bevel gear which engages with the bevel gear structure of the operating wheel 130 and rotates with respect to the movement of the operating wheel 130.
The first transmission arrangement 144 is linked with the gear arrangement 142 for transmitting the rotary motion of the gear arrangement 142 to the second transmission arrangement 146. The first transmission arrangement 144 is a belt and pulley arrangement which is connected to the first shaft 148a and the gear arrangement 142. The second transmission arrangement 146 is also a belt and pulley arrangement which is connected between the first shaft 148a and the second shaft 148b. The first transmission arrangement 144 transmits the rotary motion of the gear arrangement 142 to the second transmission arrangement 146 by rotating the first shaft 148a. As the first shaft 148a rotates, the second transmission arrangement 146 rotates and transmits the rotary motion to the second shaft 148b. The first shaft 148a and the second shaft 148b are arranged horizontally and parallelly above and below the housing 200 of the air-vent 100 respectively. Upon operating the first operating mechanism 140, the second operating mechanism is simultaneously operated through the first shaft 148a and the second shaft 148b.

In another embodiment, as shown in
Similarly, the second rack 246 is arranged in contact with the gear 242 and the second guiding member 110b. The second rack 246 reciprocates upon rotating the gear 242 and moves translationally to slide the second guiding member 110b to extend or retract towards or away from the air-vent 100. The first guiding member 110a and the second guiding member 110b move in opposite direction. By way of non-limiting example, upon rotating the operating wheel 130 in the first direction, the gear 242 rotates and moves the first rack 244 to extend the first guiding member 110a inside the air-vent 100 as shown in
Similarly, upon rotating the operating wheel 130 in the second direction, the gear 242 rotates and moves the first rack 244 to retract the first guiding member 110a from the air-vent 100 and extents the first guiding member 110a inside the air-vent 100. Wherein the first direction of the operating wheel 130 here refers to upward rotation and the second direction is downward rotation in reference to the occupant.
Further, the gear 242 is connected to a shaft 248 by a second link 262 as shown in
Therefore, the air-vent 100 for distributing air in the vehicle interior is advantageous because it occupies less space for assembling. The air-vent 100 effectively utilizes the space for operation. Further, the air-vent 100 has lesser number of constructional elements thereby making it economical. Also, the air-vent 100 is aesthetically pleasing and is robust in construction.
