Description

[Detailed Description of the Invention] This invention relates to a liquid sealing device for liquid-tightly fixing a weather strip attached to the folded portion of a folding door for a vehicle.

Conventionally, when assembling a weather strip to this type of folding door, the weather strip _W1 was fastened to the edge of the folded part _n1 using a screw B and a stopper T, for example, as shown in Figure 1A. In some cases, there is a disadvantage that the strength near the through hole h inserted to insert the screw b deteriorates and cracks that cause water leakage occur due to repeated opening and closing. As shown, when the flange part f ₁ of the folded part n ₂ is clamped by the clamping parts k ₁ and k ₁ of the weather strip w ₂ and this clamping state is fixed with a metal clip c, this clip c and the flange part There are drawbacks such as rust forming on f ₁ and deterioration of _{the assembly stability and liquid tightness of weather strip w 2.Furthermore ,} as shown in Fig _. When the weather strip _w3 is clamped by the clamping portion _k2 , there is a drawback that not only does the number of assembly steps increase, but also the number of steps required when replacing the weather strip is complicated.

In view of the above-mentioned drawbacks, the purpose of the present invention is to provide a liquid sealing device for a vehicle folding door, which can stably assemble a weather strip to the folded part of the folded door and reliably seal the folded part with liquid. It is to be.

Next, the first embodiment of the present invention will be explained with reference to the drawings. In the drawing, D is a folding door for opening and closing an opening opened on one side of the vehicle by bending it into a folded shape. , 1 is a center folding part in the center of the folding door D, and locking edges 2, 2 each having a substantially T-shaped cross section are vertically arranged in a groove shape along both opposing edges of the folding door D. There is.

Numerals 3 and 3 denote weather strips attached to the locking edge 2 of the folded part 1, respectively, which are molded from a flexible elastic material such as rubber, and are attached to the outer surface of the locking edge 2 to prevent the weather strip from being attached to the locking edge 2 of the folded part 1. A hollow closing part 4 is provided vertically to seal the joining area of the first part 1, and two proximal end edges 4a, 4a of the closing part 4 are arranged in parallel oppositely to each other to sandwich the locking edge 2. A pair of clamping parts 5, 5 are formed which are connected to each other, and each clamping part 5 has a vertically perpendicular engagement hole 6 having a substantially rectangular cross section.

Reference numeral 7 denotes a liquid-sealed clip which is straddled in a clamp-like manner over the upper ends of both clamping parts 5 and inserted into both engaging holes 6 in order to press the upper ends of both clamping parts 5 against the engaging edges 2, respectively. The clip is molded from a non-rusting material such as synthetic resin, and comprises a pair of legs 8, 8 which are arranged side by side and are each formed in an approximately quadrangular pyramid shape so as to be tightly fitted into the engaging holes 6 of both clamping parts 5 and removable therefrom to seal the engaging holes 6. A connecting piece 9 is bridged to the upper ends of both leg pieces 8 and is integrally connected to the clip, and both leg pieces 8 are inserted into the upper ends of both engaging holes 6 so that the liquid-sealed clip 7 is straddled over the upper ends of both clamping parts 5, and the vicinity of the upper end of the engaging edges 2 is clamped by both clamping parts 5.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the weather strip 3 attached to the edge of the half-folded part 1 of the half-folded door D has a locking edge 2 which is vertically installed on the edge of the half-folded part 1 and has a substantially T-shaped cross section. A closing part 4 installed vertically to be attached to the side surface, and a pair of clamping parts 5 arranged in parallel to hold the locking edge 2 and connected to both proximal end edges 4a of the closing part 4. The liquid seal clip 7 is provided to bridge the upper ends of both clamping parts 5 and press the upper ends of both clamping parts 5 to the locking edge 2. A pair of leg pieces 8 are formed in parallel to fit into the upper ends of the respective bored engagement holes 6 to seal the engagement holes 6, respectively.

Therefore, when attaching the weather strip 3 to the folded part 1, both clamping parts 5 are clamped to the locking edge 2, and then both leg pieces 8 of the liquid seal clip 7 are inserted into both engaging holes 6 of both clamping parts. When the weather strip 3 is press-inserted so as to straddle the liquid seal clip 7, the weather strip 3 can be easily and stably assembled to the locking edge 2, reducing the number of assembly steps.
As a result of restricting the expansion of the weather strip 3, the clamping state of both clamping parts 5 to the locking edge 2 is ensured.
It has the advantage of reliably sealing the bonding interface between the locking edge 2 and the locking edge 2, and preventing water from entering during rain or when washing the vehicle.

In particular, since the liquid seal clip 7 is made of a non-rusting material, rust can be prevented near the contact area between the locking edge 2 and the liquid seal clip 7, and both leg pieces 8 of the liquid seal clip 7 can be prevented from forming. Since both the engaging holes 6 are sealed in a plug-like manner at This has the effect of suppressing the deterioration of the clamping force of the clamping parts 5 over time due to repeated opening and closing of the folding door D by pressing the clamping pieces 5 into the grooves of the locking edge 2 in a filling manner.

Next, a second embodiment of the present invention will be explained according to FIG. 5. In this embodiment, a liquid seal clip 7A is used.
Both leg pieces 8A, 8A are formed in the shape of a step with a sawtooth longitudinal section, and a connecting piece 9A connecting the upper ends of both leg pieces 8A is an umbrella so as to cover the vicinity of the upper end surface of both clamping parts 5A. It is formed in the shape of

This prevents the leg pieces 8A from coming out of the engagement holes 6A, thereby stabilizing the straddling state of the liquid-sealing clip 7A, and further reliably preventing water from overflowing or flooding from the upper end of the weather strip 3A. be.

Note that other functions and effects are substantially the same as those in the first embodiment, and therefore their explanations will be omitted.

That is, the present invention provides a weather strip that is attached to the edge of the folded part of a folded door, and is attached to the outer surface of a locking edge that is vertically provided on the edge of the folded part and has a substantially T-shaped cross section. and a pair of clamping parts arranged in parallel to clamp the locking edge and connected to both proximal end edges of the closure part. The liquid-sealing clip, which is provided to bridge the upper end and press the upper ends of both clamping parts to the locking edge, has upper ends of both engaging holes respectively drilled in both clamping parts. 1 arranged in parallel in order to fit into each and seal both engagement holes respectively.
By forming a pair of leg pieces, the weather strip can be easily and stably assembled to the folded part, and the liquid tightness of the folded part can be improved. This is an extremely practical idea as a liquid sealing device for doors.
