Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a synthetic resin core for reinforcing an armrest that is attached to the inner surface of an automobile door, and more particularly to an armrest core having a unique structure.

(Prior Art) A type of armrest that is attached to the inner surface of an automobile door has an arm receiving surface that extends from the inner surface of the door in a nearly horizontal direction, and an outer wall that descends downward from the tip of the arm receiving surface and reaches the inner surface of the door. has
In addition, there is a type in which a recess for a handhold that opens into the arm receiving surface is formed on the inner surface of the door.
FIGS. 6 and 7 show an example thereof. In the figure, 100 is the arm receiving surface, and 10
2 is an outer wall, and 104 is a recess for a handhold formed by partially recessing the arm receiving surface 100 downward.

By the way, as shown in these figures,
When an armrest is constructed of a reinforcing hard synthetic resin core and a soft synthetic resin skin covering its surface, it is difficult to form the entire armrest in one piece. As shown in FIG. 8, when attempting to integrally mold a core 108 made of hard synthetic resin, a portion 112 of the mold is wrapped in the core 108 due to the presence of the recess 104, that is, the core This is because the core body 108 becomes trapped inside the body 108, and therefore the molded core body 108 cannot be removed from the mold 112.

For this reason, conventionally the armrest 106 is divided into an upper part and a lower part, as shown in FIG. and configure
Each was manufactured separately and attached to the inside surface of the door.

(Problem that the invention aims to solve) However, if the armrest is constructed by combining separate parts in this way, each part must be manufactured separately, and the number of man-hours required to install it on the door is correspondingly large. It becomes too many.

(Means for solving the problem) The core body of the present invention was devised to solve the above problem, and its gist is that the core body extends almost horizontally from the inner surface of the automobile door. It has an arm receiving surface and an outer wall that descends downward from the tip of the arm receiving surface and reaches the inner surface of the door, and a recess for a handhold that opens into the arm receiving surface is formed on the inner surface of the door. A reinforcing core body made of hard synthetic resin in a door armrest provided with a door armrest is provided with an upper plate, a wall plate, and a recess side plate respectively disposed on the back side of the arm receiving surface, the outer wall, and the side surface of the recess. An integral hinge portion having a shape corresponding to the cross-sectional shape of the armrest and allowing the recess side plate to rotate up and down is formed in a portion extending from the upper end of the recess side plate to the wall plate. A protruding portion of a predetermined length protruding toward the other side is provided on either side of the recess side plate, a member integral therewith, or the wall plate, while a corresponding abutting portion is formed on the other side. The protruding portion and the abutting portion serve as a spacing maintaining portion for maintaining a predetermined distance between the recess side plate and the wall plate, and a fixing portion for fixing the recess side plate and the wall plate. It is in what is being done.

(Effects of action and invention) In this synthetic resin core, the recess side plate arranged on the back side of the recess side surface can be rotated up and down by the integral hinge part, so that the recess can be rotated up and down. Despite the presence of , such a core can be easily integrally molded and removed from the mold. The core body was molded in an unfolded state in which the recess side plate of the core body was rotated around the integral hinge portion, that is, the space between the recess side plate, the upper plate, and the wall plate was opened. After that, by rotating the recess side plate around the integral hinge part, it can be made into the same form as the state where it is attached to the inner surface of the door. This is because the core can be easily removed from the mold.

As described above, according to the present invention, the synthetic resin core can be easily integrally molded. Based on this, it becomes possible to construct the armrest in one piece, thereby reducing the number of parts and the number of man-hours for assembling it to the door.

By the way, when a hard synthetic resin core is molded without providing an integral hinge portion as described above, the shape of the core is determined at the time of molding, and it can be used as is for assembly as an armrest component.

However, when the above-mentioned integral hinge portion is provided, the recess side plate is rotatable at the integral hinge portion during the molding stage, and the relative positions of the recess side plate, wall plate, and top plate are not determined. That is, the shape of the core is not determined. Therefore, after molding, it is necessary to determine the relative positions of the recess side plates, wall plates, and top plate to fix the shape of the core.

In this regard, in the present invention, the interval between the recess side plate and the wall plate is regulated to a predetermined interval by the contact between the protrusion provided on either the recess side plate or the wall plate and the contact portion provided on the other side. - Since the core body is held and fixed, it is possible to easily and accurately fix the core body, which has been formed in a different form from the form at the time of assembly, into the final desired shape.

After the protruding portion and the abutting portion are fixed, the shape of the core remains unchanged, and it can be used as is for assembly as an armrest component.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

In FIG. 2, a door armrest 10 is attached to the inner surface of the door 12, and is composed of a core made of hard synthetic resin and a skin made of soft synthetic resin covering the surface of the core. This armrest 10 has an arm receiving surface 14 that extends in a substantially horizontal direction from the inner surface of the door 12, and an outer wall 16 that hangs down from its tip and further extends obliquely toward the inner surface of the door. It is adapted to be attached to the inner surface of the door 12 through the provided attachment hole 18. The armrest 10 also has a bottomed recess 20 formed by recessing a portion of the arm receiving surface 14 on the inner surface of the door downward, and this recess serves as a handhold when opening and closing the door. has been done.

The structure of the reinforcing core made of hard synthetic resin in this armrest 10 is shown in FIGS. 1, 3, and 4.
As shown in the figure. As shown in the figure, this core body 25 has a shape corresponding to the armrest 10. That is, the core body 25 includes an upper plate 22 corresponding to the arm receiving surface 14 of the armrest 10, a wall plate 24 corresponding to the outer wall 16, a recess bottom plate 26 and a recess side plate corresponding to the bottom and side surfaces of the recess 20, respectively. It has 28. A mounting portion 30 is provided on the wall plate 24 portion, and the core body 25 is attached to the inner surface of the door 12 at this mounting portion 30. Further, a tongue piece 32 as an abutting part is provided on the lower surface side of the bottom plate 26, and this tongue piece 32 is connected to the protruding part of the wall plate 24 by screws 36.
It is designed to be screwed into position 4.

On the other hand, an integral hinge part 38 is formed in which the wall thickness is partially reduced at the transition part from the recess side plate 28 to the upper plate 22, and this integral hinge part 38 allows the recess side plate to 28 can be rotated in the vertical direction, that is, can be rotated in a direction away from or toward the wall plate 24.

The protruding portion 34 is configured to protrude from the back surface of the wall board 24 by a predetermined length in the lateral direction, and by abutting and fixing the protruding portion 34 and the tongue piece 32, the wall board 24 and the recess are connected. The distance between the side plate 28 and the recessed bottom plate 26 integral therewith is defined, and they are fixed. That is, the integral hinge part 3
The hard synthetic resin core body 25 having a diameter of 8 is restrained in its final shape by the abutting and fixing of the protruding portions 34 and the tongue pieces 32.

The above core body 25 is formed by forming the recess side plates 28 and the bottom plate 26 into an expanded form as shown in FIG. 5, and then rotating the recess side plates 28 and the bottom plate 26 around the integral hinge part 38. Therefore, it can be easily manufactured. When molding the recess side plate 28 and the bottom plate 26 in an expanded form, the space between the recess side plate 28 and the wall plate 24 is open, so that it can be easily removed after the core body 25 is formed. The core body 25 that can be molded and removed from the mold is pressed into the integral hinge portion 38 until the tongue piece 32 and the protruding portion 34 come into contact with the recess side plate 28 and the bottom plate 26.
By rotating the door around the
