2. Description of the Prior Art FIG. 3 is a perspective view of a general van-type vehicle 1 having a double door 5 at the rear of a packing box. 2. Description of the Related Art Conventionally, a double door 5 as shown in FIG. The door is suspended from an entrance frame 6 via a hinge 7 so as to be openable and closable. A seal structure 20 is provided between the door and the gate frame material and in a gap between the doors to prevent rainwater and dust from entering the cargo room. The closed state is maintained by the engagement between the cams provided on the upper and lower ends and the cam keeper provided on the portal frame material side. FIG. 4 is a partial cross-sectional view showing the seal structure of the double door 5 at the section opening after the packing box, which is closed by a pair of double doors that can be opened and closed by a hinge (not shown) attached to the gate frame material. .
Usually, this type of door is formed by laminating or sandwiching a plate-like core material 53 made of wood, a composite material, or the like between an outer plate 51 and an inner plate 52 made of an aluminum alloy or a synthetic resin. And a seal member 21 attached to the outer peripheral edge of the panel and hermetically closing a gap between the door and the gate frame material.

[0003] The sealing member 21 is made of vinyl chloride resin or EP.
An elastic body made of a material such as DM and formed in a substantially H-shape or an h-shape in the thickness direction. FIG. A fixed portion 22 and a seal portion 23 are respectively opened in opposite directions, and a seal portion made of a flexible material is fused and fused in an H shape based on a fixed portion made of a hard material. The sealing material at the end of the left door in the figure has an H-shaped cross section at the end, and the long tongue-shaped piece 25 outside the H-shape.
Comes into close contact with the outside of the sealing material fixing portion of the other door, and the inner short tongue-shaped piece 26 comes into contact with and comes into contact with the end face of the other door sealing material fixing portion. The sealing material at the other end of the door has an h-shaped cross section at the end, and the h-shaped tongue 27 is in close contact with the inside of the H-shaped sealing material. As shown in the partial cross-sectional view of FIG. 4, the door has an elastically deformable outer long tongue-shaped piece 25 provided on the sealing portion of the sealing material between the door and the portal frame 6 on the outer surface of the portal frame 6. In addition to the close contact, the inner short tongue-shaped piece 26 is in close contact with the inner end surface of the door frame material, thereby maintaining airtightness.

In general, the seal portion of the door of the luggage compartment has such a structure, but in order to maintain the hermeticity of the seal portion, the seal portion between the doors and the state in which the door is strongly pressed between the door and the gate frame material. In particular, if the door is closed in summer, when the temperature is high, the door frame material and the sealing material that are in pressure contact with each other will cause a bonding phenomenon such as adhesion between the sealing material and the sealing material, causing a large resistance when opening the door. May accompany. Such opening resistance of the door is due to the physicochemical adhesion phenomenon at the contact interface of these sealing materials, and is caused not only by a filler or a chemical substance such as a plasticizer contained in the sealing material, but also by the pressure contact of the sealing material. This is a phenomenon that also affects the paint film and surface shape on the body side, and is not limited to double doors, but also seals for flip-up doors and the overlap between the lower end of the L-shaped roof of a wing car and the upper end of the fan. This also occurs in the sealing material and the like applied to the sheet. If such an adhesive phenomenon occurs over the entire sealing material at the outer peripheral edge of the door even if the adhesive force itself is small, the open area resistance becomes large due to the large area as a whole. When this occurs, there is a possibility that the seal member may be damaged or the opening / closing drive unit may be hindered. Therefore, it has been demanded that the door can be smoothly opened and closed without such an adhesive phenomenon.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such a problem, and it has been proposed to prevent the adhesion of a sealing portion of a door such as a shipping carton of a van-type vehicle to prevent the door from being adhered. It is an object of the present invention to provide a sealing structure which reduces the resistance at the time of opening and does not impair the sealing effect. It is another object of the present invention to reduce the opening resistance of a door easily and inexpensively without changing the structure of a conventional sealing material.

[0006]

According to the present invention, in order to achieve the object, in a sealing material for sealing a door and an entrance frame or doors, a large number of fine notched strips are formed on a pressure contact surface of the sealing material. A sealing material for a door of a van-type vehicle packing box or the like characterized by being formed, and the sealing material has a tongue-shaped piece, which is sealed by the tongue-shaped piece and the notched strip. The height of the line is approximately 0.1 to 0.2 mm.

[0007]

[Function] By forming a large number of fine notches on the press-contact surface of the seal material, the seal material is a press-contact surface on which fine streaks are formed, and the surfaces of the seal members are pressed against each other or a member to be pressed such as a gate frame. , So that the same sealing effect as before is maintained, and the application of the striations makes the contacted portion by pressing become a line from the surface, and is distributed along a fine striation under a strong pressing force. Due to the distribution of the pressing force, the adhesion is prevented, and the opening resistance of the door is significantly reduced. Further, by forming a large number of fine notches on the press-contact surface of the tongue of the sealing material having the tongue, the height of the notches of this notch can be set to approximately 0.1-0. By setting the thickness to 2 mm, a sealing effect and an adhesion preventing effect can be effectively exhibited.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing one embodiment. FIG. 1A shows an H-shaped sealing material in which the peripheral portion of the door panel 50 is inserted into the fixing portion 22 and fixed. On the inner press-contact surface of the long tongue-like piece 25 of the sealing material, a number of notched fine strips 30 are formed parallel to the longitudinal direction from the tip of the seal material to the base portion, and the outer press-contact of the short tongue-like piece 26 is formed. The surface is similarly formed with a number of similar notched striations from the tip to the base. FIG. 1B shows an h-shaped sealing material. On the inner surface of the tongue-shaped piece 27, a number of fine jagged lines 30 are formed in the same manner in the longitudinal direction toward the tip side. . The height of these notched strips is not a ridge having a height of 1 to several mm as provided in a conventional sealing material or the like, but is a fine line having a height of about 0.1 to 0.2 mm. When the door or the like is closed, a large number of such fine stripes are formed on the entire pressure-bonded surface of the sealing material or the frame material to be pressed against. Since these striations are fine as described above, they do not exhibit a sealing action by themselves, but the sealing material formed with these many striations without hindering the sealing action of the conventional sealing material is , Exerts its original sealing action.

Since these seal materials are formed by engraving a large number of fine streaks in the above-mentioned conventional seal material, the conventional H material as shown in FIG. 5A is used. When the sealing material door is closed by applying to the pressure contact surface of the seal material of the letter and h shape, as shown in FIG. Of the h-shaped tongue-like piece 27 of the h-shaped sealing material is in close contact with the end outer surface of the h-shaped tongue-like piece 27, and the pressure-contacting face of the short tongue-shaped piece 26 that has formed the plurality of striations is the The sealing member 22 is pressed against the end face of the fixed portion 22 serving as a base portion of the sealing material and closely adheres. On the other hand, the press-contact surface of the h-shaped tongue 27 of the h-shaped sealing material provided on the other door is formed so as to be in close contact with the inner surface of the H-shaped sealing material. Therefore, the sealing effect by the press contact surface having the fine striations formed in such a close contact structure can prevent the above-mentioned adhesion phenomenon and reduce the opening resistance of the door without impairing the conventional sealing effect at all. it can. FIG. 5 (b) shows a sealing member attached to a recess of a door frame member 55 using an extruded aluminum profile panel 50. This sealing material is covered by the frame member 55 and is exposed to the outside. However, since the long tongue-shaped piece 25 of the sealing material is in close contact with the outside of the portal frame material 6 and the short tongue-shaped piece 26 is in close contact with the end face of the portal frame material, the present invention is applied to these press-contact surfaces. By applying a structure in which a large number of fine stripes are formed, a sealing effect can be exhibited, and similarly, the opening resistance can be reduced by the effect of many fine stripes.

Regarding the effect of reducing the opening resistance of the door formed with these notched fine lines, the seal portion length 400
mm H and h-shaped sealing material was provided at both ends to make a double door, the door was sealed at room temperature, and the opening resistance after a certain period of time was measured. It is reduced to about 1/3 of that of the thing.
When the resistance at opening after heating and sealing for a certain period of time was measured, the resistance at the first opening of both the product of the present invention and the conventional product was greater than that at the time of sealing at room temperature. However, the open resistance of the product of the present invention was about ２〜 to １ ／ of that of the conventional product.

In the conventional door seal material, one or more ridges are formed in the longitudinal direction of the seal material. However, these ridges prevent leakage of the seal material itself. It is intended and has a height of 1 to several mm, and has a sealing action by its deformation. The sealing material which is the object of the present invention seals the sealing material by strongly pressing the sealing material against each other or the frame material or the like at the pressure contact surface of the sealing material. The strip itself is crushed and deformed, and the effect of preventing adhesion cannot be exhibited.

FIG. 2 (a) shows a sealing structure of a superposed portion of a lower end of an L-shaped roof 61 of a wing vehicle and an upper end of a fan 60, and two semi-cylindrical cross sections on the left and right sides on the top of the fan. The sealing members 21 are spaced apart from each other with their cylindrical protrusions facing upward, and the cylindrical protrusions are placed downward on the lower end surface of the L-shaped roof in correspondence with the two sealing members. When the same semi-cylindrical sealing material 21 is disposed toward the vehicle and the L-shaped roof of the wing wheel is closed and the side of the cargo compartment is closed by closing the fan, the sealing material meshes up and down and comes into close contact. Even in the sealing material having such a close contact structure, the opening resistance can be reduced without impairing the sealing effect by forming a large number of fine notches in these press contact surfaces.
In such a wing wheel, since the entire length of the seal portion is long and the contact area is extremely large, and the load on the opening / closing drive mechanism is large, the reduction in opening resistance has a great effect. FIG. 2B shows a sealing structure of a wing wheel. The L-shaped sealing material 65 at the end of the L-shaped roof 61 includes a long tongue-shaped piece 25 and a short tongue-shaped piece 26. Are formed on the surface in close contact with each other. Such a tongue-like piece can also exhibit the same sealing effect and opening resistance reduction effect as described above.

[0013]

As described above, in the present invention, in the structure of the conventional sealing material, the sealing effect of the sealing material is formed by forming a large number of fine notches in the press contact surface. The resistance at the time of opening can be reduced by preventing the adhesion phenomenon without impairing the opening resistance, and the resistance at the time of opening can be effectively reduced by a simple structure. In addition, because of its simple configuration, it can be widely applied to conventional sealing materials made of a material such as rubber or resin, and it is a matter of course that the type of the door and the like is not limited to the double door type. That is, even if it is a sliding type or a lid type, any type of sealing material can be applied as long as the sealing material is pressed against and causes an adhesion phenomenon. The resistance at the time of opening the lid can be reduced.
