2. Description of the Related Art Since a rear part of a vehicle body of a running vehicle is in a negative pressure state, a turbulent flow is generated in the rear part of the vehicle body to wind up dust and rainwater on the road to hinder the rearward visibility and to lift the rear part of the vehicle body. This also causes the inconvenience that the traveling stability is impaired due to the occurrence of. As a measure to prevent such problems from occurring,
It has been practiced to attach a spoiler having both air flow rectifying action and lift suppressing function to the rear part of the vehicle body. This spoiler needs to have its outer shape molded into a shape calculated hydrodynamically, and since it is desirable to make it as light as possible, its material is extremely excellent in moldability and workability. , Synthetic resin with light weight and corrosion resistance is used. A typical example thereof is a reaction injection molded product or the like in which a polyurethane resin is used as a material and an insert for mounting on a vehicle body is integrally embedded.

[0003]

However, since the above-mentioned molded product has the drawback that the weight becomes heavy and the material cost and the molding cost also increase, it is relatively easy to make a hollow and lightweight molded product. It is also considered to make a spoiler by molding or rotational molding technology. However, it is difficult to embed the mounting insert integrally in such a hollow spoiler. However, the spoiler can be attached to the vehicle body without embedding the mounting insert. However, when a collision accident occurs while traveling at a relatively high speed and a strong impact force is exerted on the spoiler, those lacking the mounting insert will generate strong concentrated stress at the mounting part on the vehicle body and stress destruction at this part. It is easy to get rid of, and there is a possibility that a spoiler that is thrown off may cause harm to people and things around. Therefore, in some countries, legislation obliges the structure to prevent the spoiler from being separated from the vehicle body by the external force in the event of a collision and jumping around. Therefore, the object of the present invention is to provide a hollow spoiler made of synthetic resin for an automobile, which is constructed so that it will not separate from the vehicle body and bounce around even if its mounting part is broken by external force in the event of a collision accident. To provide a spoiler.

[0004]

To achieve the above object, an automobile spoiler according to the present invention is made of synthetic resin and has a hollow shape, and mounting portions 2 to the vehicle body are provided near both ends in the longitudinal direction thereof. Along with the spoiler body 1 provided with insertion holes 7 in the vicinity of the mounting portion 2 and through the insertion holes 7 and 7 near the both ends, the wire or the rope-shaped member is inserted into the inner space of the spoiler body 1. And the tough binding member 6, the connecting portions 10 such as loops and connecting fittings provided at both ends of the binding member 6, and the spoiler main body 1 attached to the vehicle body, A fixing means 3 for fixing the parts 10 to the vehicle body is provided. As the fixing means 3, a mounting bolt for fixing the mounting portion 2 to the vehicle body may be directed thereto, and the connecting portion 10 may be hooked on the mounting bolt 3.

[0005]

The bundling member 6 in which the inner space of the hollow spoiler is inserted in the longitudinal direction thereof is provided at both ends, and the connecting portions 10 and 1 are provided.
0 is fixed to the vehicle body by fixing means 3 and 3.
Should a collision accident occur, the impact force will be applied as concentrated stress to the mounting portion 2 of the synthetic resin spoiler, which is relatively inferior in strength, to the vehicle body, and even if this mounting portion 2 is stress-damaged, it will be tough. Since the wire-like binding member 6, the connecting portions 10 at both ends thereof, and the fixing means 3 that is fixed to the vehicle body and fixes the connecting portion 10 are unlikely to have a destructive force, the spoiler is It becomes a state of being caught by the binding material 6, and it is prevented from splashing around.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle spoiler A, in this case a rear spoiler, according to the present invention will be described below with reference to FIGS. As shown in the figure, the spoiler body 1 formed in a hollow shape is made of hard synthetic resin, and blow molding,
It is made by rotational molding, injection molding or any other suitable molding technique. The overall length is substantially equal to the lateral width of the rear part of the vehicle body, both ends are formed in a pointed shape, and are curved so as to follow the curved surface of the outer surface of the body B of the automobile. Spoiler body 1
Mounting portions 2 and 2 to the body B are integrally provided near both ends of the lower surface of the body. 1 and 2, the shape of the mounting portion 2 is drawn slightly different.

On the lower surface of each mounting portion 2, the spoiler body 1
The bracket 4 assembled with the mounting bolts 3 for mounting on the body B is mounted by the two tapping screws 5. Also, on the bottom surface of the spoiler body 1, each bracket 4
Insertion holes 7 and 7 through which a binding material 6 described below is inserted are provided adjacent to (see FIG. 2).

The bundling material 6 of this embodiment shown in FIG.
The spoiler body 1 is a stainless steel wire (or rope) having a length that allows the inner space of the spoiler body 1 to be inserted in the longitudinal direction thereof, and has a thickness of about 1.5 mm. The tying material 6 is covered with a soft tube 8 made of soft vinyl chloride or the like so that the tying material 6 does not generate contact noise when it comes into contact with the inner wall surface of the spoiler body 1. Both ends of the bundling member 6 which is inserted through the inner space of the spoiler body 1 are bent into a loop shape as shown in FIG.
Then, crimping is performed to form a loop-shaped connecting portion 10. Reference numeral 11 is a waterproof / buffering packing made of foamed neoprene rubber that is attached to the lower surface of the mounting portion 2.

In the spoiler A, the mounting bolts 3 are attached to the respective mounting portions 2 and 2 of the spoiler main body 1 as described above, and both ends of the binding member 6 in which the inner hollow portion of the spoiler main body 1 is inserted. As shown in FIGS. 1 and 2, the connecting portions 10 and 10 are hooked on the legs of the mounting bolts 3 and 3, respectively, and are completely assembled and supplied to the market. In this case, mounting bolt 3
Also serves as a fixing means of the connecting portion 10.

Next, the operation of the above configuration will be described. In order to attach the spoiler A to the upper surface of the rear portion of the body B, first, bolt holes for screwing the attachment bolts 3 are opened at the positions where the attachment portions 2 and 2 of the body B are brought into contact with each other. However, it is also possible to form a bolt hole in the vehicle body component below the body B and to place an insertion hole for the mounting bolt 3 in the body B. Then, the two mounting bolts 3 and 3 projecting from the lower surface of the spoiler body 1 are inserted into the bolt holes of the body B, and the nut 12 screwed at the tip thereof is tightened, whereby the spoiler to the body B is spoiled. Installation of A is easy.

If a vehicle equipped with the spoiler A has a collision accident while traveling at a high speed, a large concentrated stress is generated in the mounting portion 2 of the synthetic resin spoiler body 1 which is relatively inferior in toughness. There is a high possibility that the mounting portion 2 will be stress-damaged. If it is destroyed, there is a possibility that the spoiler body 1 bounces off and hits people or objects in the vicinity to cause harm. By the way, the spoiler A
Even if the spoiler body 1 is detached from the body B, both ends of the tough binding material 6 inserted into the inner space of the spoiler body 1 are screwed to the body B through the connecting portions 10 and fixed to the mounting bolts 3. The spoiler body 1 is, as it were, a binding material 6
It is in a state of being bound to body B by. Then, at the time of collision, up to this fixed portion is destroyed, and the connecting portion 10
Is unlikely to fall off the mounting bolt 3, so even if the spoiler body 1 is broken into two in the middle, it is almost certainly prevented from separating from the vehicle body and bouncing off. .

3 and 4 show another embodiment of the present invention. The difference from the above embodiment is the fixing means for fixing the mounting bolt 3 to the mounting portion 2 of the spoiler body 1.
That is, the bracket 3a that is welded to the base end (lower end) of the mounting bolt 3 and serves as the mounting base portion is integrally embedded in the mounting portion 2 when the spoiler body 1 is molded. Therefore, the troublesome work of attaching the mounting bolt 3 to the spoiler body 1 and the tapping screw 5 can be omitted.

In the above structure, the binding material 6 is not limited to the metal wire material, but may be a rope made of tough synthetic fiber, for example, and the connecting portion 10 is replaced with the loop portion of the binding material 6. It may be a metal fitting such as a metal ring. Further, by adopting a fixing structure of the binding material 6 that exerts a tensile force on both ends of the binding material 6, the soft tube 8 can be omitted. Also, the fixing structure for fixing the mounting portion 2 to the vehicle body,
Of course, the object of the present invention can be achieved even if the detailed configuration is not limited to that shown in the drawings and the design is appropriately changed.

[0014]

[Effects of the Invention] As is clear from the above description, the spoiler for automobiles according to the present invention is made of a synthetic resin having excellent molding / workability, light weight, corrosion resistance and the like in a hollow shape. In addition to the advantage of being lightweight and inexpensive, in the event of a collision accident, even if a synthetic resin spoiler with relatively low strength is destroyed by the impact force, the inner space of the hollow spoiler body The tough tying material that is inserted into the section and fixed at both ends to the vehicle body keeps the spoiler tied to the vehicle body. For this reason, the spoiler can be separated from the vehicle body and bounce off, which can almost certainly eliminate the risk of harming people and objects in the vicinity.
It also has extremely important safety advantages.
