DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a smoke tube mounted on a vehicle in a passenger compartment.

[0002]

2. Description of the Related Art A vehicle is required to be provided with a smoke tube, which can be easily taken out of the cowl side trim of a cabin so that the smoke tube can be taken out immediately. Is held.

[0003] When holding the smoke tube,
Conventionally, as shown in, for example, Japanese Utility Model Publication No. 4-11882, a holding portion having an insertion hole through which the smoke tube can be inserted is integrally and horizontally protruded from the interior side of the cowl side trim. At the same time, a rib having a diameter slightly smaller than that of the smoke tube is provided on the inner peripheral surface of the insertion hole in the holding portion, and the outer peripheral surface of the smoke tube is pressed against the rib when the smoke tube is inserted into the insertion hole. Thereby, the smoke tube is inserted and held in the holding portion.

[0004]

However, according to the conventional holding structure described above, the holding portion is provided horizontally on the cowl side trim, and the smoke emission tube inserted and held in the insertion hole of the holding portion is also provided. Because it is in a horizontal position, when taking out the smoke tube from the holding portion to the rear side of the vehicle, it is necessary to extract the smoke tube in the horizontal direction along the holding portion, and it is difficult to quickly take out the smoke tube. The smoke flares are arranged horizontally below the cowl side trim and near the feet of the occupants so as not to disturb the occupants during normal times. Not only is it difficult to grasp by hand, it is difficult to extract the smoke tube in the horizontal direction near the foot while holding the smoke tube, and it is difficult to take out the smoke tube.

[0005] Further, since it is necessary to easily take out the smoke canister from the holding portion to the outside, and to securely hold the smoke holding portion in the holding portion, an accurate insertion hole or rib of the holding portion is required. Accuracy is required, and there has been a problem that the production of the holding section becomes difficult and the production cost is increased. That is, in order to reliably hold the smoke tube in the holding portion, the rib formed in the insertion hole of the holding portion may have a small diameter, and the rib may have a large pressure contact holding force with respect to the smoke tube. However, in this case, the smoke tube can be strongly held by the holding portion, but it is difficult to quickly remove the smoke tube from the holding portion. In particular, the smoke tube is Since the side trim is located near the feet of the occupant and is difficult to take out, it is more difficult to take out the smoke canister. On the other hand, in order to facilitate the removal of the smoke canister from the holding portion, it is sufficient to increase the diameter of the rib and reduce the pressure contact holding force of the rib with respect to the smoke canister. It is also conceivable that the smoke flaring may come off from the holding part without force due to inertia force at the time of sudden start, etc., and in particular, as described above, the holding part is provided horizontally on the cowl side trim, and the holding is performed. When the smoke tube is held horizontally in the insertion hole of the part, the smoke tube is more likely to come out, for example, when the vehicle is suddenly started, and when the diameter of the rib is increased, the rib and the smoke tube are There is also a problem that the backlash is easily generated between the flare and the rib due to the backlash.

Further, in the above publication, in order to enhance the holding strength of the smoke tube in the holding portion, a clip is separately attached to a rear side of the holding position of the smoke tube in the holding portion, and the clip is attached to the holding portion via the clip. Although the held rear part of the smoke tube is also engaged and held in a holding manner, in such a case, not only the number of parts is increased and the production cost is increased, but also the smoke tube is increased. The quick removal of the smoke flares becomes more difficult due to the presence of the clip when removing the smoke tube.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to securely hold a flaring cylinder at a predetermined position without the flaring tube falling out without permission, while simplifying the structure and reducing the manufacturing cost. Another object of the present invention is to provide a structure for holding a smoke canister which can quickly and easily take out the smoke canister in an emergency.

[0008]

In order to achieve the above object, the present invention relates to a structure for holding a smoke tube mounted in a vehicle interior to a vehicle, wherein the smoke tube 4 is provided on an inner side wall 2 of the vehicle interior. A holding portion 3 having an insertion hole 31 that can be inserted is formed integrally with the inner wall 2 so as to protrude into the vehicle interior, and the insertion hole 31 in the holding portion 3 is obliquely downwardly directed toward the front of the vehicle. A pressing surface 21 that elastically presses the outer peripheral surface of the smoke emission tube 4 inserted into the holding portion 3 toward the vehicle interior, on the inner wall 2 at the front portion of the holding portion 3.
Was formed.

[0009]

When the smoke tube 4 is held by the holding portion 3, the smoke tube 4 is inserted into the insertion hole 31 of the holding portion 3 so that the leading end of the smoke tube 4 faces the pressing surface 21 of the inner side wall 2. Then, the pressing surface 21 applies an elastic pressing force toward the inside of the cabin toward the front end of the smoke emitting tube 4 through the pressing surface 21, whereby the outer peripheral surface of the smoke emitting tube 4 is inserted into the insertion hole. 31 is pressed against the inner peripheral wall of the cylinder 31 so that the smoke tube 4 is reliably elastically held between the insertion hole 31 and the pressing surface 21. Therefore, when the vehicle suddenly starts, the smoke tube 4 is It is possible to reliably prevent the cylinder from slipping out of the holding portion 3 without permission.
By causing the holding portion 3 to be pressed and held with the elastic pressing force of 1, the generation of abnormal noise between the holding portion 3 and the smoke canister 4 can be reliably prevented.

Further, since the insertion hole 31 of the holding portion 3 is inclined obliquely downward toward the front of the vehicle, when the smoke tube 4 is inserted and held in the insertion hole 31, the smoke tube 4
Is held in an inclined position in which the front end side in the insertion direction is located downward, and the rear side gripped by hand when taking out the smoke canister 4 is located upward, and therefore, when the vehicle suddenly starts, etc. The smoke tube 4 can be more reliably prevented from arbitrarily coming out of the holding portion 3 to the rear side.
When taking out the smoke canister 4 from the holding portion 3 to the rear side of the vehicle, even if the smoke canister 4 is held near the foot of the occupant on the lower side of the inner side wall 2 so as not to obstruct the occupant. The user can easily grip the rear part of the smoke canister 4 located at an obliquely upper side after taking it out, and can easily grasp the smoke canister 4. Further, by pulling the smoke canister 4 grasped by hand diagonally rearward, the smoke is emitted. The smoke tube 4 can be easily and quickly taken out to the outside against the elastic pressing force of the pressing surface 21.

[0011] In addition, by simply forming the pressing surface 21 on the inner side wall 2 located on the front side in the insertion direction of the smoke canister 4, the smoke canister 4 can be reliably held.
Since it is possible to take out the smoke canister 4 to the outside quickly and easily, it is possible to reduce the manufacturing cost while simplifying the structure without increasing the manufacturing cost unlike the conventional one.

[0012]

FIG. 1 schematically shows the interior of a vehicle compartment on the front side of a vehicle, in which an inner side wall 2 of the vehicle compartment is provided in front of an opening 1 for opening and closing a front side door. In FIG. 1, a cylindrical holding portion 3 is provided on the inner surface side of a cowl side trim 2 provided on one side in the vehicle width direction of the vehicle compartment, and the smoke emitting tube 4 is held by the holding portion 3 so as to be able to be taken out.

When holding the smoke canister 4, as shown in detail in FIG. 2, the holding portion 3 is integrally formed so as to project from a part of the cowl side trim 2 toward the vehicle interior. At the same time, the holding portion 3 is inclined so that the rear side of the vehicle is at a high position and the front side of the vehicle is at a low position, and the insertion hole 31 through which the smoke emitting tube 4 is inserted into the holding portion 3 is held. In the cowl side trim 2, a part of the outer peripheral surface of the smoke emission tube 4 inserted into the holding portion 3 is inserted into the cowl side trim 2 at a position in front of the holding portion 3 while the vehicle is formed. The pressing surface 21 that elastically presses the room is formed.

More specifically, the holding portion 3 is formed integrally with the cowl side trim 2 when the cowl side trim 2 is formed of a synthetic resin. In order to enable extraction to the outside, an opening window 22 for die-cutting is formed in the formation portion of the holding portion 3 at the middle of the cowl side trim 2 in the front-rear direction, and a portion facing the opening window 22 is formed. In addition, the holding portion 3 is integrally formed so as to protrude toward the vehicle interior, and the front end side of the cowl side trim 2 at the leading end side in the insertion direction of the smoke emission tube 4 inserted into the holding portion 3, The receiving wall 23 with which the tip comes into contact when the smoke emitting tube 4 is inserted is integrally formed so as to protrude toward the vehicle interior. The front end of the smoke generating tube 4 is connected to the pressing surface 21, extends obliquely rearward from the continuous portion, and the rear end is inserted into the holding portion 3. An inclined wall 24 located outside the vehicle compartment and connected to the front end side of the holding portion 3
And the inclined wall 24 and the receiving wall 2 are integrally formed.
3, when the smoke tube 4 is not inserted into the holding portion 3, as shown by the phantom line in FIG. Further, when the smoke tube 4 is inserted into the holding portion 3, the smoke tube 4 is elastically pressed against a part of the outer peripheral surface on the distal end side of the smoke tube 4 as shown by a solid line in FIG. The pressing surface 21 for applying a pressing force to the vehicle interior side is formed.

It is preferable that the holding portion 3 has an upward inclination angle of about 5 degrees with respect to a straight line extending in the horizontal direction, so that the smoke tube 4 is taken out from the holding portion 3. Work can be done well, and
When the vehicle suddenly starts, etc., it is possible to satisfactorily prevent the smoke tube 4 from coming out of the holding portion 3 toward the rear of the vehicle.

Further, the smoke emitting tube 4 comprises a cylindrical smoke emitting tube main body 41 and a cover 42 for covering the outside of the main body 41. The main body 41 and the cover 42 are respectively provided on the rear side in the longitudinal direction. Arc-shaped engaging portion 4 swelling outward
The cover 42 is covered so as not to be detached from the main body 41 by engaging the engaging portions 43 with each other.

In the embodiment shown in FIG. 1, a projection 2 is provided at a position behind the holding portion 3 in the cowl side trim 2.
When the smoke tube 4 is inserted into and held by the holding portion 3, the engaging portion 43 provided on the smoke tube 4 is locked to the front side of the projection 24. In this case, it is possible to more reliably prevent the smoke emitting tube 4 from coming out of the holding portion 3 to the rear side due to the sudden start of the vehicle or the like via the projections 24 and the engaging portions 43.

In the above embodiment, the holding portion 3 is integrally provided on the cowl side trim 2 in an obliquely inclined shape such that the rear side of the vehicle is at a high position and the front side of the vehicle is at a low position. Although the insertion hole 31 through which the smoke emitting tube 4 is inserted is formed in the same direction as the inclination direction, the holding portion 3 is provided horizontally on the cowl side trim 2 in the present invention. The insertion hole 31 may be formed in the holding portion 3 so as to be inclined so that the rear side of the vehicle is at a high position and the front side of the vehicle is at a low position.

Next, the operation of the above configuration will be described. First, when the smoke tube 4 is held by the holding portion 3, the smoke tube 4 is inserted into the insertion hole 31 of the holding portion 3.
The insertion tip side is the pressing surface 2 of the cowl side trim 2.
2, the pressing surface 21 is pressed through the smoke emission tube 4 to the outside of the passenger compartment as shown by the solid line in FIG. An elastic pressing force directed toward the vehicle interior is applied to the front end side in the insertion direction of the smoke canister 4 on the surface 21, whereby the outer peripheral portion of the smoke canister 4 is pressed against the inner peripheral wall surface of the insertion hole 31, The smoke tube 4 is reliably elastically held between the insertion hole 41 and the pressing surface 21. Therefore, it is possible to reliably prevent the smoke tube 4 from slipping out of the holding portion 3 without permission at the time of sudden start of the vehicle, etc., and furthermore, to press the smoke tube 4 with the elastic pressing force of the pressing surface 21. By pressing and holding to the side 3, it is possible to reliably prevent generation of abnormal noise between the holding portion 3 and the smoke canister 4.

Further, since the insertion hole 31 of the holding portion 3 is inclined obliquely downward toward the front of the vehicle, when the smoke tube 4 is inserted and held in the insertion hole 31, the smoke tube 4 , The tip side in the insertion direction is positioned downward, and the rear side gripped by hand at the time of taking out the smoke canister 4 is tilted and held in a state where it is positioned upward.
When the vehicle suddenly starts, etc., it is possible to more reliably prevent the smoke tube 4 from arbitrarily falling out of the holding portion 3 to the rear side,
In addition, when taking out the smoke canister 4 from the holding portion 3 to the rear side of the vehicle, the smoke canister 4 is held near the foot of the occupant at the lower side of the cowl side trim 2 so that the smoke canister 4 does not obstruct the occupant. In this case, the user can easily grip the smoke emitting tube 4 located at the obliquely upper side after removing the smoke emitting tube 4 so that the user can easily grip the smoke emitting tube 4. Thus, the smoke canister 4 can be easily and quickly taken out to the outside against the elastic pressing force of the pressing surface 21.

[0021] Moreover, only by forming the pressing surface 21 on the cowl side trim 2 on the front side of the holding portion 3, the smoke canister 4 can be securely held.
Since it is possible to take out the smoke canister 4 to the outside quickly and easily, it is possible to reduce the manufacturing cost while simplifying the structure without increasing the manufacturing cost unlike the conventional one.

[0022]

As described above, according to the present invention, the holding portion 3 having the insertion hole 31 through which the smoke tube 4 can be inserted is provided on the inner side wall 2 of the vehicle interior with respect to the inner side wall 2. And the insertion hole 31 in the holding portion 3 is inclined obliquely downward toward the front of the vehicle, while the inner wall 2 at the front portion of the holding portion 3
Since the pressing surface 21 for elastically pressing the outer peripheral surface of the smoke emitting tube 4 inserted into the holding portion 3 toward the vehicle interior is formed, the smoke emitting tube 4 is inserted and held in the insertion hole 31 of the holding portion 3. At this time, the pressing surface 21 provided on the inner side wall 2 applies an elastic pressing force to the smoke generating tube 4, and accordingly, the smoke generating tube 4 is pressed against the insertion hole 31 side, so that the insertion hole 31 and the pressing surface 21 are pressed. The smoke flaring 4 can be reliably held elastically between, and therefore, it is possible to reliably prevent the smoke flaring 4 from slipping out of the holding portion 3 without permission at the time of sudden start of the vehicle, and the like. By pressing and holding the smoke generating tube 4 toward the holding portion 3 with the elastic pressing force of the pressing surface 21, it is possible to reliably prevent generation of abnormal noise between the holding portion 3 and the smoke generating tube 4. can do.

Since the insertion hole 31 of the holding portion 3 is inclined obliquely downward toward the front of the vehicle, when the smoke tube 4 is inserted and held in the insertion hole 31, the smoke tube 4 The tip side in the insertion direction is located at the lower side, and the rear side gripped by hand at the time of taking out the smoke canister 4 is held in the inclined position located at the upper side.
When the vehicle suddenly starts, etc., it is possible to more reliably prevent the smoke tube 4 from arbitrarily falling out of the holding portion 3 to the rear side,
In addition, when taking out the smoke canister 4 from the holding portion 3 toward the rear side of the vehicle, the smoke canister 4 is held near the foot of the occupant at the lower side of the inner side wall 2 so that the smoke canister 4 does not obstruct the occupant. Even if it is, it is easy to put a hand on the rear side of the smoke canister 4 that is positioned obliquely above and can be easily grasped, and the smoke canister 4 grasped by hand can be pulled out obliquely rearward. Thus, the smoke canister 4 can be easily and quickly taken out to the outside against the elastic pressing force of the pressing surface 21. In addition, by simply forming the pressing surface 21 on the inner side wall 2 located on the front side in the insertion direction of the smoke canister 4, the smoke canister 4 can be securely held. Since it can be taken out quickly and easily, the production cost can be reduced while simplifying the structure without increasing the production cost unlike the conventional one.
