[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a clip for holding a lower end of a drain hose for drainage provided in each part of an automobile.

[0002]

2. Description of the Related Art As a conventional clip of this type, for example,
There is one shown in Japanese Utility Model Publication No. 2-45056. The conventional clip is developed to hold a lower end of a drain hose connected to a ceiling side of a sunroof vehicle, and includes a tubular main body portion into which a lower end of the drain hose is fitted, Locking means for locking the cylindrical main body portion to the mounting hole of the panel. In actual use, the cylindrical main body portion is mounted to the mounting hole of the panel via the locking means, If the lower end of the drain hose is internally fitted to the connection port, the lower end of the drain hose can be held on the panel side. Therefore, rainwater or the like on the ceiling of the vehicle is drained out of the vehicle from the drain port of the clip body through the drain hose thus held.

[0003]

However, the structure in which the lower end of the drain hose is internally fitted into the connection port of the clip main body has an advantage that it is easier to secure the watertightness of both than the externally fitted structure. However, in the conventional clip, since the lower end side of the drain hose is simply fitted inside the connection port of the cylindrical main body, the outer diameter of the drain hose and the cylindrical main body Needless to say, when the diameter difference from the inner diameter of the connection port is large, even if the diameter difference between the two is as small as possible, the lower end of the drain hose becomes cylindrical when subjected to external force such as running vibration. There has been a sufficient risk that rainwater or the like may inadvertently come off from the connection port of the main body and enter the vehicle.

[0004] Further, the conventional clip has a locking means for locking the cylindrical main body portion into the mounting hole of the panel,
The locking means itself uses the characteristics of an elastic material such as rubber to forcibly deform and lock the hole of the mounting hole while forcibly deforming it. In addition, there is a problem that the work is difficult.

[0005]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the above-mentioned problems of the conventional clip. The first invention is a plate-like member which comes into contact with the outer surface of a panel having a mounting hole. A flange portion, and a tubular pipe portion for internally fitting the lower end of the drain hose on the inner surface side of the panel, the tubular pipe portion being integrally connected to the plate flange portion at a desired angle, Plate-shaped flange of tubular pipe and tubular
Only the inner wall surface side of angle sandwiched by the outer wall surface of the pipe portion is an acute angle, pinched by and its distal end is cylindrical in accordance with the lower end wall of the drain hose in its thickness in cooperation with the inner wall surface Pipe
An elastic holding piece protruding outward from the leading edge of the portion is provided, and a locking means for locking from the inner surface side to the edge of the mounting hole of the panel is provided on the outer wall surface side. In addition, the second invention is based on the above-mentioned first invention, and is based on a cylindrical pipe portion.
Of the pipe is elastically clamped to the center axis of the cylindrical pipe.
A configuration in which the side on which the piece is provided is formed low is adopted.

[0006]

According to the present invention, when the tubular pipe portion of the clip is completely inserted into the mounting hole while the tubular pipe portion of the clip faces the mounting hole from the outer surface side of the panel, The clip itself can be attached to the mounting hole of the panel with one touch by the action of the flange-shaped flange and the locking means, so that part of the lower end wall of the drain hose is elastically connected to the inner wall surface of the cylindrical pipe part. If the lower end of the drain hose is fitted inside the tubular pipe while being sandwiched between the holding pieces, this makes it possible to easily hold the lower end of the drain hose.

However, in this holding state, a part of the lower end of the drain hose fitted inside the tubular pipe is securely held between the inner wall surface of the tubular pipe and the elastic holding piece. Therefore, even if an external force such as running vibration is applied, not only does the lower end of the drain hose not carelessly come off from the tubular pipe portion, but also the outer diameter of the drain hose may be temporarily reduced. Even if the diameter is considerably smaller than the inner diameter of the pipe,
It is possible to securely hold the lower end of the small-diameter drain hose.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to an embodiment illustrating the present invention. The clip according to the embodiment is an integrally molded product of a synthetic resin and has a mounting hole as shown in FIGS. A plate-like flange portion 1 abutting on the outer surface of the vehicle body panel and a tubular pipe portion 2 on the inner surface side of the panel, into which the lower end of the drain hose is fitted. 1 are connected integrally at a desired angle, and the inside thereof is placed in a state of communicating with the opening 1 a of the plate-like flange portion 1.

In this embodiment, a part of the wall of the lower end 7a of the drain hose 7 is formed on the inner wall surface 2a side of the tubular pipe portion 2 in cooperation with the inner wall surface 2a. An elastic clamping piece 3 to be clamped is provided at a desired distance from the inner wall surface 2a, and the tip 3a of the elastic clamping piece 3 is
And the inner wall surface 2a of the opposing outer wall surfaces of the cylindrical pipe portion 2 is formed.
On the side where the elastic holding piece 3 is provided, that is, on the outer wall surface 2c where the angle between the plate-shaped flange portion 1 and the pipe outer wall surface is an acute angle. A bead portion 4 having a locking groove 4a formed in the vicinity of the plate-like flange portion 1 and having a tapered surface gradually separated from the outer wall surface 2c in the direction and engaging the hole edge of the mounting hole H of the panel P; Outer wall 2d on the outer wall 2d
And a pair of rib walls 5 defining a space S between the rib walls 5 are formed at a desired interval, and are elastically locked between the respective rib walls 5 from the inner surface to the edge of the mounting hole H. Elastic claw 6 is provided. In this case, the distance between the elastic holding piece 3 and the inner wall surface 2a of the tubular pipe portion 2 is
It is preferable that the thickness be slightly smaller than the thickness of the drain hose 7. 3 and 4, the distal end 2b of the tubular pipe portion 2 is lower on the side where the elastic holding piece 3 is provided. That is, the surface formed by the leading edge 2b with respect to the center axis O is a surface inclined toward the elastic holding piece 3 side.

Therefore, when the lower end portion 7a of the drain hose 7 connected to the ceiling side of the sunroof vehicle is to be held by using the holding clip having such a configuration, first, the outer side OUT The engaging groove 4a of the bead portion 4 provided on one of the opposed outer wall surfaces 2c of the tubular pipe portion 2 while the tubular pipe portion 2 of the clip faces the inside of the mounting hole H.
When the cylindrical pipe portion 2 is completely inserted into the mounting hole H in a state where the corresponding hole edge of the mounting hole H is engaged therein, the elastic locking claw 6 formed on the other opposed outer wall surface 2d is formed. Is elastically locked to the hole edge of the corresponding mounting hole H while bending inward, so that the clip itself can be attached to the mounting hole H of the panel P with one touch.

Incidentally, when the clip is mounted,
The pair of rib walls 5 are pressed against the peripheral surface of the mounting hole H to effectively prevent the movement of the clip itself, and
Of the elastic locking claw 6 can be prevented while keeping the bending of the elastic locking claw 6 constant, so that not only is the mounting state of the clip itself very stable, but also the outer surface O of the panel P is thereby improved.
Water can be reliably prevented from entering the inside from the UT. Although not specifically shown, if a seal washer or the like is provided on the back surface of the plate-like flange portion 1, it goes without saying that watertightness is further ensured.

Then, finally, from the inner side IN of the panel P, the lower end wall 7a of the drain hose 7 is clamped between the inner wall surface 2a of the tubular pipe portion 2 and the elastic holding piece 3, If the lower end 7a of the drain hose 7 is forcibly fitted inside the tubular pipe portion 2, the lower end 7a
Can be held on the panel P side,
In this state, the lower end portion 7a of the drain hose 7 fitted inside the tubular pipe portion 2 is partially elastically held with the inner wall surface 2a of the tubular pipe portion 2 as shown in FIG. 3, the lower end 7a of the drain hose 7 comes off the tubular pipe 2 accidentally even if it receives an external force such as running vibration. Not only does this occur, but even if the outer diameter of the drain hose 7 is considerably smaller than the inner diameter of the tubular pipe part 2, the small diameter 7 can be securely held.
In this embodiment, the distal end portion 3a of the elastic holding piece 3 is projected outward from the distal end edge 2b of the tubular pipe portion 2. Therefore, in FIG. When fitted inside the tubular pipe portion 2, the tip 3a protruding outward serves as an insertion guide for the lower end 7a of the drain hose 7, thereby improving workability. Further, at this time, the surface formed by the distal end edge 2b of the tubular pipe portion 2 is a surface inclined to the elastic holding piece 3 side with respect to the center axis O as described above. In addition, the insertion workability is improved.

Therefore, when the drain hose 7 is securely held, rainwater or the like on the ceiling of the vehicle is efficiently drained out of the vehicle from the opening 1a of the plate-like flange 1 through the drain hose 7. However, at this time, as described above, there is no fear that the lower end portion 7a of the drain hose 7 will come off from the inside of the tubular pipe portion 2 irrespective of its outer diameter. It is possible to eliminate intrusion into the vehicle.

In the above embodiment, the lower end 7a of the drain hose 7 connected to the ceiling side of the sunroof vehicle is described as being held. However, the present invention is not limited to this. It goes without saying that the present invention can be easily applied to other drainage hoses connected to various parts such as around a trunk and an air conditioner unit. Also, the connecting angle of the tubular pipe portion 2 to the plate-like flange portion 1 is not limited to the illustrated inclination angle, and may be connected at a vertical angle in accordance with the arrangement line of the drain hose 7 or the like. Alternatively, it is sufficiently possible to connect them at another arbitrary angle.

[0015]

[Effect of the invention] As mentioned above, the present invention is similar to the conventional retaining clip, is intended to assume a configuration that fitted into the lower end of the drain hose into the tubular pipe section, but first devising
Below, an elastic holding piece is provided on the inner wall surface side of the tubular pipe portion, and a part of the lower end of the drain hose is elastically held between the elastic holding piece and the inner wall surface of the tubular pipe portion. Therefore, even if an external force such as running vibration is applied, the lower end of the drain hose does not accidentally come off from the inside of the tubular pipe portion. Can be prevented from invading. or,
This holding action of the elastic holding piece is effective not only when the drain hose itself is deteriorated and becomes thinner, but also when the outer diameter of the drain hose is considerably smaller than the inner diameter of the tubular pipe portion. However, since the small-diameter drain hose can be securely held, the flexibility of the drain hose to be held can be greatly enhanced. In addition to this, the elastic holding piece is
Inside the side where the angle between the outer wall of the pipe and the outer wall is acute
Provided only on the wall surface, and its tip is the tip of the tubular pipe.
Since it is configured to protrude outward from the edge,
Of internal fitting work to the tubular pipe of the hose itself
You can expect it.

Also, under the second invention , in addition to this,
The leading edge of the tubular pipe is aligned with the center axis of the tubular pipe.
And the side where the elastic holding piece is provided is lower
In the first invention, the synergy with the elastic holding piece
Improve the work of fitting the ren hose inside the tubular pipe.
We can expect much more.
