JP5257985B2 - Outside air introduction device attached to the window frame of automobiles - Google Patents

Description

  The present invention relates to the technical field of automobiles, and more particularly, to the technical field of taking traveling wind into a room.

  When traveling on a closed course such as a circuit with a general commercial vehicle (such as a private car), various rules are defined in order to prevent injury (see Non-Patent Document 1).

  For example, in the case of an open car, as well as wearing a helmet or seat belt, it is often necessary to attach a roll gauge assuming a fall. Further, taping may be required because headlights, tail lamps, and the like may be damaged by contact or the like, and fragments may be scattered on the road surface.

  One such rule is "Do not drive with the windows (especially the driver's seat windows) open". Experience has shown that if you are running with the window open, your hands will be reflected from the window at the time of a fall, leading to arm loss or fractures due to the momentum of the fall. Because.

  Therefore, it is necessary to attach a driver snet (net) to the window frame when traveling with the window closed or with the window opened.

  However, traveling with the windows closed inevitably heats up the room. Especially in summer, the temperature is very high and it is not possible to concentrate on driving. In severe cases, dehydration may occur. It should be noted that the problem of heat can be cleared by operating the air conditioner, but the engine power is consumed accordingly, so it is usually not operated when traveling on the circuit. In the first place, many vehicles are not equipped with air conditioners.

  On the other hand, when a driver's net is installed, a certain amount of driving wind can be taken into the room, but the outside air does not enter the room as expected because the net is stretched over the entire side glass. In addition, the visibility is hindered by the net, and there is also a problem that the net flutters due to running wind.

  The present invention has been made to solve these problems.

The present invention is an outside air introduction device that is attached to a window frame of an automobile and is sandwiched and fixed by a side glass, and is configured to fill a gap space formed between the side glass and the window frame by lowering the side glass by a certain amount. A main body portion, a first through hole formed through the main body portion in the vehicle interior / exterior direction, and formed to project outward and open forward, and communicate with the first through hole. said by the forward position than definitive outside air introduction path to the main body portion, a second through hole for releasing the interior of the air to the outside is formed by the negative pressure generated when traveling with provided and the outside air introducing passage, the It tries to solve the problem.

This outside air introducing device is attached so as to be sandwiched between the side glass and the window frame after a certain amount of the side glass of the automobile is pulled down. At this time, since the outside air introduction path projects outwardly and opens forward, the outside air is taken into the vehicle very efficiently through the outside air introduction path when the vehicle is running with the device attached. . Further, since the shape of the main body is a shape that fills the gap space between the side glass and the window frame, there is no risk that the driver accidentally puts out a hand from the window even when the vehicle falls over.
Furthermore, it is possible to prevent the interior of the vehicle from becoming an excessively positive pressure state with the introduction of outside air. If the inside of the vehicle is in an excessively positive pressure state, the introduction of outside air from the outside air introduction path is hindered, but since the air inside the vehicle is released from this second through hole, the rise in the inside pressure of the vehicle is suppressed. It is possible to introduce and ventilate outside air without waste. In other words, even when the traveling speed is the same, more outside air can be introduced into the vehicle.

  Further, a fitting groove into which the upper surface of the side glass can be fitted is formed on the lower surface of the main body portion, and the thickness of the upper surface of the main body portion may be the same as the thickness of the side glass. .

  If it does in this way, it is not necessary to prepare an attachment member separately and to fix the said external air introduction apparatus to a window frame or a side glass. That is, the outside air introduction device can be easily and reliably attached using the vertical movement of the side glass.

  In addition, it is particularly effective to form the second through hole so as to be positioned in the vicinity of the A pillar at the time of attachment. The vicinity of the A pillar (position just behind the A pillar) is in a negative pressure state due to the air flow during traveling. The negative pressure acts to pull out the air in the vehicle, and the air in the vehicle can be effectively removed.

  Moreover, you may connect a flexible pipe etc. to the vehicle inside of the said 1st through-hole.

  With such a configuration, the introduced outside air can be blown out in a desired direction, so that the outside air can be blown out at a position most comfortable for the driver.

  According to the present invention, outside air can be efficiently introduced while ensuring the safety of the driver. Also, the device can be easily attached and detached.

The figure which showed roughly the attachment procedure of the external air introduction apparatus. The figure which showed the state which attached the flexible pipe to the vehicle inside.

  Hereinafter, an outside air introduction device 10 according to an example of an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the outside air introduction device 10 is attached so as to be sandwiched between the front side glass 6 and the window frame 5 of the automobile 1. In the present embodiment, it is attached to the side of the driver's seat of the automobile 1. Of course, it may be attached to the passenger seat side, or a configuration to be attached to the rear seat side may be employed.

  The main body portion 11 of the outside air introduction device 10 is a plate-like body bent in a substantially “bent” shape when viewed from the front. That is, it is shaped so as to extend from the A-pillar 4 of the automobile 1 to the roof 3 at the time of mounting, and when the front side glass 6 is lowered by a certain amount, a gap space is formed between the front side glass 6 and the window frame 5. 20 (not shown in FIG. 1; see FIG. 6) can be filled exactly.

  Reference numeral 2 denotes a windshield, reference numeral 7 denotes a door knob, reference numeral 8 denotes a rear side glass, and reference numeral 9 denotes a door.

  As shown in FIGS. 2 to 5, an outside air introduction path 13 is formed substantially at the center of the main body 11. The outside air introduction path 13 is formed so as to project outward from the vehicle when the apparatus 10 is attached to the vehicle 1. Further, the outside air introduction path 13 has an opening 13a that opens to the front side (the front side of the automobile 1). In addition, an outside air introduction hole 12 penetrating in the vehicle interior / exterior direction is formed in the main body 11, and an outside air introduction path 13 is formed so as to communicate with the outside air introduction hole 12. That is, the outside air that has entered the opening 13 a can be blown out from the outside air introduction hole 12 toward the room through the outside air introduction path 13.

  The size and shape of the outside air introduction hole 12 can be appropriately changed as necessary. Further, the size and shape of the outside air introduction path 13 and the opening 13a can be freely changed as long as the outside air passage 13 and the opening 13a project outward and open forward (that is, as long as outside air can be actively taken in by traveling). be able to.

  Further, three escape holes (second through holes) 14 are formed in front of the outside air introduction path 13 in the main body 11. In the present embodiment, the escape hole 14 is formed so as to be located in the vicinity of the A pillar 4 (a position immediately behind the A pillar 4) in a state where the device 10 is attached. The escape hole 14 is a hole for allowing the air inside the vehicle to escape to the outside of the vehicle.

  Further, a ridge portion 15 is formed on the lower surface 11 b side of the main body portion 11. This convex part 15 is formed in each of the front side and the back side of the main-body part 11, As a result, the fitting groove 15a is formed (refer FIG. 5). The fitting groove 15a is used for attachment of the outside air introducing device 10 and has a width D2 in which the upper surface 6a of the front side glass 6 can be just fitted. That is, it is formed to be slightly wider than the thickness D3 of the front side glass 6.

  In addition, although the protruding item | line part 15 is comprised as a member integrally molded with the main-body part 11 in this embodiment, you may comprise so that another member may be bonded together.

  On the other hand, the thickness D1 of the upper surface 11a of the main body 11 is configured to be substantially the same as the thickness D3 of the front side glass 6. That is, the thickness is such that it can be fitted in a groove (groove into which the upper surface 6a of the front side glass 6 is fitted) 5a originally provided in the window frame 5 instead of the front side glass 6.

  The attachment of the outside air introduction device 10 is performed according to a procedure as shown in FIG.

  First, the front side glass 6 is lowered by a certain amount. Then, it attaches so that the external air introduction apparatus 10 may be inserted | pinched in the clearance gap 20 formed between the front side glass 6 and the window frame 5. FIG. More specifically, after attaching the upper surface 11a of the main body 11 of the outside air introduction device 10 to the groove 5a originally provided in the window frame 5 (the groove in which the upper surface 6a of the front side glass 6 is originally fitted) 5a. Then, the front side glass 6 is pulled up and fixed so that the device 10 is sandwiched between the window frame 5 and the front side glass 6. At this time, the upper surface 6 a of the front side glass 6 is fitted into a fitting groove 15 a formed in the lower surface 11 b of the main body 11.

  As described above, the outside air introduction device 10 is firmly clamped and fixed by the window frame 5 and the front side glass 6, so that the outside air introduction device 10 is not shaken by vibration or wind pressure due to traveling.

  If the vehicle travels with the outside air introduction device 10 attached as described above, fresh outside air is guided into the vehicle through the opening 13a, the outside air introduction path 13 and the outside air introduction hole 12. That is, an increase in the interior temperature can be prevented by introducing the outside air. Furthermore, the presence of the escape hole 14 prevents the interior of the vehicle from becoming an excessively positive pressure state, so that outside air can be introduced efficiently.

  Moreover, in this embodiment, since the escape hole 14 is formed in the vicinity of the A pillar 4, it is possible to efficiently escape the air in the vehicle. This is because the vicinity of the A pillar 4 (a position immediately behind the A pillar 4) is in a negative pressure state due to the air flow during traveling, and thus the air inside the vehicle is actively pulled out of the vehicle.

<Other configuration examples>

  In addition, this invention is not limited to the said embodiment, A various specific structure is employable unless it deviates from a claim.

  The material of the outside air introduction device 10 can be configured using various materials. For example, if a glass fiber reinforced plastic is used, a high strength product can be manufactured at low cost. Further, if carbon fiber reinforced plastic or Kevlar fiber reinforced plastic is used, higher strength and light weight can be realized. Further, if a transparent acrylic resin is used, the maximum field of view can be secured even if the outside air introducing device 10 is attached. Of course, other types of resins, metals, and combinations thereof can also be used.

  Further, as shown in FIG. 7, a projection 12 a is formed on the vehicle interior side of the outside air introduction hole 12, and a flexible pipe 16 capable of holding its own shape is attached to the projection 12 a, thereby introducing the introduced outside air. It is also possible to make it blow out in a desired direction. With such a configuration, the introduced outside air can be blown out in a desired direction, so that the outside air can be blown out at a position most comfortable for the driver.

  In addition, the outside air introduced into the vehicle is not only directed to the driver, but can also be prevented from malfunctioning by directing it toward a device (instruments, etc.) that is susceptible to heat in the vehicle.

  Further, the position of the escape hole 14 is not necessarily in the vicinity of the A pillar 4, and may be provided at a position behind the outside air introduction path 13, or may be provided at both of these positions. In addition, the shape and number of the escape holes 14 are not particularly limited, and the design can be changed as appropriate.

  In addition, although not shown, a lock device may be provided so that the outside air introduction device 10 is not dropped even when the outside air introduction device 10 is accidentally loosened. For example, the outside air introduction device 10 and the vehicle side may be connected with a wire or the like.

  The automobile 1 described above is a so-called “four-door” automobile, but can be similarly applied to a “two-door” automobile.

  The outside air introducing device according to the present invention is used by being attached to a window frame when traveling on a closed course such as a circuit as a hobby in a private car or the like.
