Description

  The present invention relates to a vehicle assist grip provided on, for example, a roof side portion or a pillar portion in an automobile interior for supporting an occupant's body and a mounting structure thereof.

  As a structure of this type of conventional vehicle assist grip, for example, a structure described in Patent Document 1 has been proposed. In the structure of the assist grip for a vehicle described in Patent Document 1, the leg has a grip portion and leg portions provided at both ends of the grip portion and is formed in a substantially U shape. The part is provided with a tiltable recess on the outer peripheral part of the vehicle body mounting seat surface. In the structure of the assist grip for a vehicle, an attachment portion into which an attachment screw is inserted is formed in the leg portion, and a lid body that covers the attachment portion and the attachment screw is attached via a hinge portion. These lids and hinges are formed integrally with the legs.

  According to the structure of the conventional vehicle assist grip, when the vehicle is covered with the interior material by the mounting screw, when the vehicle receives an unexpected impact, the vehicle assist grip itself is used as a fulcrum. It is said that the above-mentioned impact can be absorbed and dispersed and relaxed by tilting displacement (see, in particular, FIG. 5 of Patent Document 1).

JP 2000-103276 A

  However, the structure of a conventional vehicle assist grip represented by Patent Document 1 is not limited to the case where an unexpected impact is applied. For example, when a load is applied due to the weight of an occupant, the assist grip is more or less attached. Since it will be bent and deformed from the fixed part by the screw, the lid cannot follow the deformation of the assist grip, and the lid will be disengaged and the lid will open, and the appearance will be impaired. There was a problem of being. This is based on the fact that the hinge portion of the lid is set at the farthest position toward the load loading position of the assist grip.

  Here, depending on the specifications or grade of the interior of the automobile, a predetermined gap may be secured between the vehicle body panel to which the assist grip is screwed and fixed and the interior material covering the body panel. Then, for example, at the attachment position of the assist grip formed of a relatively hard resin material, a metal collar corresponding to the size of the gap is used to fill the gap between the vehicle body panel and the interior material. Then, the assist grip is screwed and fixed to the vehicle body panel, but in this case as well, the lid may open as described above.

  The present invention has been made paying attention to such a problem, and provides an assist grip for a vehicle and a mounting structure thereof in consideration of being able to prevent the lid from opening when a load is applied.

  In the first aspect of the invention, the vehicular assist grip is formed so as to protrude from both end surfaces in the longitudinal direction of the grip body with a stepped portion that functions as a handle portion, and the front end surface is formed. From a direction opposite to the protruding direction of the boss part on the same axis as the boss part, a boss part functioning as a seating surface to the vehicle body panel, an attachment hole formed penetrating along the axial direction of the boss part A receiving recess that is formed to open to the outside and receives the head of the screw member inserted into the mounting hole, and is bent at a position corresponding to the opening edge of the receiving recess and the end surface of the grip body. And an end cap which is hinged so as to close the opening of the housing recess.

  More specifically, as described in claim 2, an inner bottom surface of the housing recess is formed on the opposite side of the end surface of the grip body from the protruding direction of the boss portion, and is attached to the inner bottom surface. It is assumed that the hole is open and the inner bottom surface is a seating surface of the head of the screw member inserted into the mounting hole.

  Alternatively, as described in claim 3, the inner bottom surface of the housing recess is formed on the protruding direction side of the boss portion from the end surface of the grip body, and the mounting hole is opened on the inner bottom surface, It is assumed that the inner bottom surface is a seating surface of the head of the screw member inserted into the mounting hole.

  In addition, as described in claim 4, each of the boss part, the hinge part, and the end cap is integrally formed of a resin material together with the grip body.

  Furthermore, as defined in claim 5, the angle formed between the center line that bisects the thickness of the grip body and the tip surface of the boss portion is set to an acute angle while being orthogonal to the longitudinal direction of the grip body. It shall be.

  As the attachment structure of the vehicle assist grip, as described in claim 6, an interior material is disposed on the surface side of the vehicle body panel, and an end surface of the grip body is disposed on the interior material, and a boss portion is provided. The front end surface is seated on the vehicle body panel, and the end surface of the grip body and the front end surface of the boss are seated and fixed to the vehicle body panel by a screw member inserted into the mounting hole. Suppose that

  More specifically, as described in claim 7, it is assumed that interior materials are arranged on the surface side of the vehicle body panel with a gap therebetween.

  Therefore, in at least the invention according to claim 1, the assist grip is screwed and fixed with the tip surface of the boss portion seated on the vehicle body panel, while the end cap is located away from the tip surface of the boss portion. It will be hinged with. Therefore, when the load is loaded, the assist grip is bent and deformed with the seating portion of the boss portion with respect to the vehicle body panel as a fulcrum, so that the end cap can follow the deformation of the assist grip as a whole. This prevents the end cap from opening when a load is applied.

  According to the first and second aspects of the present invention, the end cap is not opened when a load is applied to the assist grip, and the appearance is good.

  According to the third aspect of the present invention, the seating portion of the boss portion with respect to the vehicle body panel and the seating surface of the head of the screw member with respect to the boss portion come close to each other. There is an advantage that the state can be maintained more stably.

  According to the invention described in claims 6 and 7, the stepped portion formed by the end face of the grip body and the boss portion is seated on the interior material covering the vehicle body panel. It will be a thing.

These respectively show enlarged sectional views along the line AA in FIG. 3 is an enlarged perspective view of a portion Q in FIG. 1, and FIG. 4 is an enlarged sectional view taken along line BB in FIG.

  As shown in FIGS. 1 and 2, the assist lip 1 is attached to the roof side corresponding portion or the pillar corresponding portion in the vehicle cabin with a predetermined inclination posture. At the mounting position of the assist grip 1, the vehicle body panel is a vehicle body strength member (a roof side rail corresponds to a roof side equivalent part, and a pillar inner panel corresponds to a pillar equivalent part) 2. The vehicle body panel 2 is covered by arranging a flexible or flexible interior material 3 such as garnish with a predetermined gap G therebetween.

  In the present embodiment, as shown in FIG. 2, the both ends of the assist grip 1 in the longitudinal direction are seated on the interior material 3, and the boss portion 6 described later is seated on the vehicle body panel 2, and the boss portion The vehicle body panel 2 is firmly fastened and fixed to the vehicle body panel 2 by mounting bolts 11 penetrating the vehicle 6. The assist grip 1 is formed mainly of a grip body 4 that functions as a handle portion. As shown in FIG. 1, the grip body 4 has a solid circular or oval cross-sectional shape, and has a substantially arched shape so that a necessary space can be ensured between the grip body 4 and the interior material 3 when the occupant grips the grip body 4. It is formed as a shape or a horizontally long deformed U-shape.

  Both ends in the longitudinal direction of the grip body 4 function as mounting bases 5 for the vehicle body panel 2, and both end surfaces 5 a functioning as seating surfaces for the interior material 3 of the mounting base 5 are cylindrical. The boss portion 6 is formed to protrude. Here, as shown in FIG. 2, if the vehicle body panel 2 and the interior material 3 covering the vehicle body panel 2 are parallel to each other, the end surface 5a of the mounting base portion 5 on which the boss portion 6 is projected is also formed. A boss portion 6 that is parallel to the interior material 3 and has a slightly smaller diameter than the both end surfaces 5a is formed with a stepped portion S. As shown in the figure, the center line L1 that bisects the thickness of the grip body 4 while being orthogonal to the longitudinal direction of the grip body 4 in the inclined posture (the direction perpendicular to the paper surface in FIG. 2) and the end surface of the mounting base 5 If the angle θ1 formed by 5a and the angle θ2 formed by the center line L1 and the vehicle body panel 2 are both defined as the mounting angle of the assist grip 1 (θ1 = θ2), the mounting angles θ1, θ2 of the assist grip 1 are defined. Is set to have an acute angle.

  As shown in FIGS. 1 and 2, the mounting base 5 at both ends of the grip body 4 is above the boss 6, that is, on the same axis as the boss 6, opposite to the protruding direction of the boss 6. A housing recess 7 for a mounting bolt 11 to be described later is formed so as to open to the outside from the direction. Furthermore, as shown in FIG. 2, the opening of the receiving recess 7 is located at a position corresponding to the end face 5 a of the mounting base 5 on the opening edge of the receiving recess 7 in the direction opposite to the protruding direction of the tilted grip body 4. An end cap 8 for closing the cover is extended through a thin hinge 9. FIG. 1 shows a state in which both end caps 8 are opened.

  More specifically, as shown in FIG. 3 in addition to FIG. 2, the end cap 8 is formed integrally with the grip body 4 together with the hinge portion 9 by using, for example, a hard resin material. 7, and a shape that matches the opening edge portion 7, and can be bent from the hinge portion 9. Further, as shown in FIG. 3, the opening edge of the accommodating recess 7 is formed in a so-called stepped shape, and the end cap 8 is fitted so as to receive the thickness of the end cap 8 at the opening edge. It comes to match.

  As shown in FIGS. 2, 3, and 4, the inner bottom surface 7 a of the accommodating recess 7 is parallel to the end surface 5 a of the mounting base 5 and is shared as one end surface of the boss portion 6. The inner bottom surface 7 a of the housing recess 7 is located on the opposite side of the protruding direction of the boss 6 from the end surface 5 a of the mounting base 5 when the end surface 5 a of the mounting base 5 is used as a reference. And the attachment hole 10 is formed so that the boss | hub part 6 may be penetrated to the axial center direction from this inner bottom face 7a. The front end surface 6a of the boss 6 through which the mounting hole 10 is formed is parallel to the end surface 5a of the mounting base 5, and the end surface 5a of the mounting base 5 is seated on the interior material 3 as shown in FIG. At the same time, the front end surface 6a of the boss portion 6 is set to be seated on the vehicle body panel 2.

  Then, as shown in FIGS. 2 and 3, with the end cap 8 opened, a mounting bolt 11 as a screw member is inserted into the mounting hole 10, and the head 11a is inserted into the inner bottom surface 7a of the housing recess 7. The assist grip 1 is firmly fixed by being fastened to the nut 12 on the vehicle body panel 2 side while being seated on the body. In this state, the end cap 8 is bent toward the grip body 4 to close the opening of the housing recess 7 so that the space of the housing recess 7 is concealed from the outside together with the head 11 a of the mounting bolt 11. The nut 12 is, for example, a weld nut type, and is welded and fixed to the vehicle body panel 2 side in advance.

  Here, as shown in FIGS. 3 and 4, main body side locking claws 13 are formed to project from both inner wall surfaces of the housing recess 7, while cap side locking claws 14 are formed on the back surface of the end cap 8. Protrusions are formed. Then, when the end cap 8 is closed, the main-side locking claw 13 and the cap-side locking claw 14 mesh with each other or engage with each other so that the closed state of the end cap 8 is self-held. It has become.

  Therefore, according to such a structure of the assist grip 1, the fastening and fixing state by the mounting bolt 11 described above is as shown in FIG. In this state, when a load is applied to the grip body 4, the vehicle body panel 2 on which the boss 6 is seated functions as a strength member and bears the load applied to the grip body 4. . However, even if the end surface 5 a of the mounting base 5 is seated so as to be in close contact with the interior material 3, this is only for improving the appearance and imparting design properties, so that the interior material 3 loads the grip body 4. There is no direct bearing of the applied load.

  For example, when a load F is applied substantially orthogonal to the center line L1 shown in FIG. , Θ2 is bent and deformed in the direction of the load F to reduce the angle θ2.

  That is, FIG. 5 is a diagram for explaining the behavior when the load load F of FIG. 2 is applied. As shown in FIG. 5, when the load load F is applied, the grip body 4 is substantially 5 is bent and deformed generally in the direction of the arrow M from the root portion with respect to the vehicle body panel 2, and a state indicated by a broken line R in FIG. And the mounting base 5 end surface 5a located near the head 11a of the mounting bolt 11 by the gap G formed between the vehicle body panel 2 and the interior material 3, and the interior material 3 on which the end surface 5a is seated, It follows the bending deformation of the grip body 4 as a whole as described above. In FIG. 5, the protrusion E in FIG. 2 is not shown. Further, the state shown by the broken line R in FIG. 5 is exaggerated for easy understanding.

  This is exactly the same for the end cap 8, that is, the end cap 8 is positioned closer to the head 11 a of the mounting bolt 11 by the gap G than the front end surface 6 a of the boss portion 6. Are connected via a hinge portion 9 at a position corresponding to the end face 5a. Therefore, the hinge portion 9 and the end cap 8 also follow the bending deformation in the direction of arrow M as the entire grip body 4 with the tip surface 6a of the boss portion 6 as a fulcrum portion or root portion, and the load F is Even if it acts, the closed state of the end cap 8 is maintained.

  Thereby, even if the hinge portion 9 of the end cap 8 is set at the farthest position toward the load load position on the assist grip 1, the end cap 8 follows the bending deformation of the grip body 4 as in the past. There will be no situation where you can't open it.

  The direction of the load F shown in FIG. 2 is merely an example for explaining the behavior, and it goes without saying that the load may be applied from a direction that is not necessarily perpendicular to the center line L1 in practice. Yes.

  FIG. 6 shows an enlarged cross-sectional view of a portion equivalent to FIG. 5 as a second embodiment for carrying out the vehicle assist grip according to the present invention. In FIG. 6, parts that are the same as those in FIG. 5 are given the same reference numerals, and redundant descriptions are omitted.

  In the second embodiment shown in FIG. 6, as is apparent from comparison with FIG. 5, the space of the accommodation recess 17 for the mounting bolt 21 that is a screw member is extended to the boss portion 6 side. The inner bottom surface 17a is set so as to be positioned on the vehicle body panel 2 side beyond the position of the end surface 5a of the mounting base portion 5, that is, on the protruding direction side of the boss portion 6. In addition, the space of the accommodation recessed part 17 extended to the boss | hub part 6 side is set to the magnitude | size which can accommodate the said head 21a, without interfering with the head 21a of the attachment bolt 21. FIG. Further, the inner bottom surface 17a of the housing recess 17 functions as a seating surface of the head 21a of the mounting bolt 21, as in the first embodiment shown in FIG.

  Therefore, also in this second embodiment, when the load is applied to the grip body 4 in the same direction as the load F in FIG. 2, the entire grip body 4 has the tip surface 6a of the boss 6 as a fulcrum or root. Will be bent and deformed in the direction of the arrow M to be in the state indicated by the broken line R, and the same effect as in the first embodiment will be obtained.

  Further, in the second embodiment shown in FIG. 6, the inner bottom surface 17 a of the housing recess 17 that functions as a seating surface of the head 21 a of the mounting bolt 21 is provided in the vehicle body as compared with the first embodiment of FIG. 5. Since it is set at a position closer to the panel 2, there is an advantage that the fastening and fixing state of the assist grip 1 by the mounting bolt 21 can be maintained more stably.
