20090144940
The present application is based on and incorporates herein by reference Japanese Patent Application No. 2007-315003 filed on Dec. 5, 2007.
The present invention relates to a mounting structure of a door grip wherein the door grip is mounted to a inner panel via an interior base material.
As a mounting structure for this kind of door grip, the mounting structure disclosed in Japanese Unexamined Patent Publication No. 2003-312351 has been well-known. This door grip is composed of a grip base mounted to a inner panel and a grip cover for covering the surface of the grip base. On the other hand, provided in the interior base material is a hole penetrating therethrough. In the grip base, a pair of mounting bosses that extends toward the inner panel side from the surface side of the interior base material as penetrating through said hole is provided. Screw-fixing both mounting bosses from the inner side of a compartment to the inner panel allows the grip base to be fixed to the inner panel at two points.
However, regarding the above door grip, the grip base is fixed to the inner panel merely at two points, thereby causing a trouble as below. For example, such as that the door grip is twisted regarding an axis line passing through both mounting bosses as a reference, a clearance appears between the door grip and the hole in the interior base material, or an abnormal noise generates when the door grip and the interior base material rub each other. In response to the above, preventing the generation of such a clearance and an abnormal noise by directly fixing the door grip to the interior base material can be conceived. However, the interior base material may deform by flexure due to the weak strength of the interior base material when stress in the tensional direction acts on the door grip.
An object of the present invention is to hold a door grip in a normal posture in a configuration in which the door grip is mounted to an interior base material.
The present invention relates to a mounting structure of a door grip in a door for the vehicle and comprises: an inner panel composing a door body, an interior base material arranged so as to oppose to the inner side of a compartment of the inner panel, a door grip fixed to the inner panel via the interior base material and having a pair of connecting parts to be connected to the interior base material, and a fixing member for fixing the interior base material to the inner panel, wherein the fixing member is arranged in both sides of the connecting part regarding the axis line passing through both connecting parts as a reference, and at least a pair of the fixing members is respectively provided in each connecting part.
In such configuration, when the door grip is twisted by a strong grip on the door grip, the interior base material intends to deform by flexure with a stress applied to both connecting parts. In response, the interior base material is fixed to the inner panel by at least a pair of the fixing members that is arranged in both sides of the connecting part regarding the axis line passing through both connecting parts as a reference, such that the deformation by flexure of the inner base material can be restrained, thereby preventing a twist of the door grip. As mentioned, this, also as a mounting structure of the door grip to the interior base material, allows the door grip to be held in a normal posture.
The following configuration is preferred as an embodiment of the present invention. The surface of the door grip may be covered with a skin, and both connecting parts may be screw-fixed from the outside of a compartment of the interior base material. Such configuration allows the door grip left in a state covered with a skin to be screw-fixed to the interior base material, while enhancing the design effect of the door grip since no screwing section is shown on the design surface of the door grip.
An interior part may be mounted to the inner side of a compartment of the interior base material, and the fixing member may be configured to fix the interior base material and the interior part to the inner panel. Such configuration allows the fixing member to double as a fixing member of the interior base material and of the interior part, and thereby fixing the interior base material to the inner panel with this fixing member. Consequently, the structure of the interior base material can be simplified.
A hole for attaching the interior part may be penetrated in the interior base material, and the fixing member may be provided inside of the hole. Such configuration allows the fixing member to be screw-fixed to the inner panel from the inner side of a compartment through the hole, and attaching the interior part to the hole can hide the fixing member from the outside.
A bracket may be comprised for connecting one connecting part among both connecting parts and the fixing member arranged in the side corresponding to this connecting part. Such configuration allows the door grip to be fixed to the inner panel through the bracket. Consequently, the mounting strength of the door grip can be enhanced.
According to the present invention, a door grip can be held in a normal posture in a configuration in which the door grip is mounted to an interior base material.
As referring now to
The middle board 21 to which the door grip 1 is mounted is described. On the outer surface of a compartment of the middle board 21, as shown in
As shown in
In the central part in the inner side of a compartment of the middle board 21, an armrest 50 is attached to allow an occupant seated in the seat to put his/her elbow. In addition, a door grip 30 is attached in the front of the armrest 50 in the inner side of a compartment of the middle board 21. The door grip 30 is formed so as to extend obliquely upward and be connected forward from the front end of the armrest 50.
The door grip 30 is connected to the middle board 21 at two points, where the front side connecting part is a first connecting part 31A, while the rear side connecting part is a second connecting part 31B. In the position adjacent to the front of the second connecting part 31B in the middle board 21, a first hole 24 is penetrated. A switch panel 80 (one example of “interior part” in the present invention) to which such as a switch for switching operation of a power window is attached, is fitted into the first hole 24. Additionally, inside of the first hole 24, a board fixing member (one example of “fixing member” in the present invention) 26 for screw-fixing the middle board 21 to the inner panel 10 with a fastening bolt B is provided.
On the other hand, in the position adjacent to the upper part of the first connecting part 31A in the middle board 21, an inside handle member (one example of “interior part” in the present invention) 60 is provided. In addition, in a joint part with the inside handle member 60 in the middle board 21, as shown in
The inside handle member 60 has a handle cover 61 to be fitted in the second hole 27. The handle cover 61 is screw-fixed to a base member 27A provided on the peripheral edge of the second hole 27. The handle cover 61 has a recess part which is recessed toward the outside of a compartment. A handle 62 is housed in the recess part in the handle cover 61. The handle 62 has a shape extending forward from the rear end side. The front end side of the handle 62 is rotationally manipulable regarding the rear end side as a rotation center. A cover fixing member (one example of “fixing member” in the present invention) 63 is provided so as to open in the recess part in the handle cover 61. As illustrated in
A skin is previously adhered to the surface of the door grip 30 according to the present embodiment. As mentioned, when a skin is adhered to the surface of the door grip 30, the door grip 30 cannot be screw-fixed to the inner panel 10 from the inner side of a compartment of the middle board 21. And therefore, in the present embodiment, the door grip 30 is firstly fixed to the middle board 21, and the middle board 21 is then fixed to the inner panel 10. However, the door grip 30 is fixed to the middle board 21 at two connecting parts 31A and 31B arranged in the front-rear direction of a vehicle, and furthermore, the middle board 21 has a lower rigidity than the inner panel 10. Consequently, the door grip 30 might be twisted around the axis (direction R), as illustrated in
Firstly, the definition of the axis line P1 of the door grip 30 is explained. Three first bolting parts 32A are provided in the first connecting part 31A. The first connecting part 31A and the middle board 21 are fixed to these first bolting parts 32A by the fastening bolts B by screw-fixing from the outside of a compartment. On the other hand, three second bolting parts 32B are provided in the second connecting part 31B. The second connecting part 31B and the middle board 21 are fixed to these second bolting parts 32B by the fastening bolts B by screw-fixing from the outside of a compartment. Here, when the center of gravity or the center of figure of a triangle having three first bolting parts 32A as its three vertices is a center of gravity G1 of the first connecting part 31A, and when the center of gravity or the center of figure of a triangle having three second bolting parts 32B as its three vertices is a center of gravity G2 of the second connecting part 31B, a straight line passing through both centers of gravity G1 and G2 is an axis line P1.
In the joint part with the first connecting part 31A in the middle board 21, there provided a pair of fixing members in both sides of the axis line P1, and one fixing member is composed of a clip seat 25, while the other is composed of a cover fixing member 63. And also, the first bolting part 32A and the cover fixing member 63 are connected by a metallic bracket 70.
On the other hand, in the joint part with the second connecting part 31B in the middle board 21, there provided a pair of fixing members in both sides of the axis line P1, and one fixing member is composed of a clip seat 25, while the other is composed of a board fixing member 26. And also, the second bolting part 32B and the board fixing member 26 are connected by the metallic bracket 70.
The first connecting part 31A (the first bolting part 32A), the middle board 21, and one end of the bracket 70 are fastened together from the outside of a compartment of the middle board 21 by the fastening bolt B. In addition, the clip seat 25 is fixed, with the clip 40 fitted into the opening 11 in the inner panel 10. Moreover, the cover fixing member 63, the other end of the bracket 70, and the inner panel 10 are fastened together from the inner side of a compartment of the middle board 21 by the fastening bolt B. As mentioned above, the handle cover 61 provided with the cover fixing member 63 is screw-fixed to a base member 27A of the second hole 27 that opens in the middle board 21. Additionally, the cover fixing member 63 is covered with the cover member 64, so that the bolting part of the fastening bolt B cannot be seen from the outside.
The second connecting part 31B (the second bolting part 32B), the middle board 21, and one end of the bracket 70 are fastened together from the outside of a compartment of the middle board 21 by the fastening bolt B. In addition, the clip seat 25 is fixed, with the clip 40 fitted into the opening 11 in the inner panel 10. Moreover, the board fixing member 26, the other end of the bracket 70, and the inner panel 10 are fastened together from the inner side of a compartment of the middle board 21 by the fastening bolt B. Additionally, the board fixing member 26 is covered with the armrest 50, so that the bolting part of the fastening bolt B cannot be seen from the outside.
The present invention has the above-mentioned configuration, and its action is hereinafter described. When the door grip 30 is pulled powerfully by an occupant seated in the seat, the middle board 21 intends to deform by flexure with the stress received from the first connecting part 31A, however, the clip seat 25 and the cover fixing member 63 respectively arranged in both sides of the first connecting part 31A are fixed to the inner panel 10 such that the deformation by flexure of the middle board 21 is restrained, thereby holding the door grip 30 in a normal posture. This allows to prevent a clearance between the handle cover 61 and the first connecting part 31A, as well as an abnormal noise caused by the rub between the handle cover 61 and the first connecting part 31A, from generating. Furthermore, the first connecting part 31A in the present embodiment is connected to the cover fixing member 63 by the bracket 70, so that the mounting strength of the door grip 30 can be enhanced.
On the other hand, similarly in the second connecting part 31B, the middle board 21 intends to deform by flexure with the stress received from the second connecting part 31B, however, the clip seat 25 and the board fixing member 26 respectively arranged in both sides of the second connecting part 31B are fixed to the inner panel 10 such that the deformation by flexure of the middle board 21 is restrained, thereby holding the door grip 30 in a normal posture. Furthermore, the second connecting part 31B in the present embodiment is connected to the board fixing member 26 by the bracket 70, so that the mounting strength of the door grip 30 can be enhanced.
Next, a method for assembling the door trim 1 for the vehicle is simply explained. Firstly, the handle cover 61 is fitted into the second hole 27 to be screw-fixed to the base member 27A, and then the door grip 30 and the armrest 50 are set in the center position in the inner side of a compartment of the middle board 21. Next, the armrest 50 is screw-fixed from the outside of a compartment of the middle board 21 by the fastening bolt B, and at the same time, both bolting parts 32A and 32B of the door grip 30 and one end side of the bracket 70 are screw-fixed from the outside of a compartment of the middle board 21 by the fastening bolt B.
Next, the middle board 21 with the door grip 30 mounted thereto is mounted to the inner panel 10. This mounting work is conducted by fitting the clip 40 attached to the projecting end of the clip seat 25 into the opening 11 in the inner panel 10. And then, the cover fixing member 63 and the other end of the bracket 70 are screw-fixed to the inner panel 10 from the inner side of a compartment of the middle board 21 by the fastening bolt B. Following this, attaching the cover member 64 to the handle cover 61 allows the fastening bolt B fixing the cover fixing member 63 to be hidden from the outside.
And also, the board fixing member 26 and the other end of the bracket 70 are screw-fixed to the inner panel 10 from the inner side of a compartment of the middle board 21 by the fastening bolt B. Following this, fitting the switch panel 80 into the first hole 24 allows the fastening bolt B fixing the board fixing member 26 to be hidden from the outside. In this manner, the assembly of the door trim 1 for the vehicle completes.
According to the present embodiment, as mentioned, both connecting parts 31A and 31B arranged at both ends of the door grip 30 are fixed to the middle board 21, while the middle board 21 is fixed to the inner panel 10 at four points: both clip seats 25 respectively arranged in both sides of the door grip 30 regarding the axis line P1 of the door grip 30 as a reference, the board fixing member 26, and the cover fixing member 63. Consequently, the rotational movement of the door grip 30 around the axis line P1 can be restrained even when the door grip 30 is gripped and pulled powerfully, thereby holding the door grip 30 in a normal posture.
As mentioned, the door grip 30 with a skin adhered to the surface thereof can be connected to the middle board 21, and thus, no screwing section appears on the design surface of the door grip 30. Therefore, the design effect of the door grip 30 can be enhanced. In addition, the middle board 21 is fixed to the inner panel 10 by the cover fixing member 63, thereby simplifying the mounting structure of the door grip 30.
Furthermore, the board fixing member 26 and the cover fixing member 63 are screw-fixed from the inner side of a compartment of the middle board 21 by the use of the first hole 24 and the second hole 27, and then, after the completion of the screw-fixing, the switch panel 80 and the handle cover 61 are attached so as to hide the fastening bolt B from the outside.
In addition, the use of the bracket 70 fixes the connecting part 31A in the door grip 30 and the cover fixing member 63, while connecting the connecting part 31B in the door grip 30 and the board fixing member 26, so that the mounting strength of the door grip 30 can be enhanced.
