Description

  The present invention relates to an assist grip that is provided in a passenger compartment of an automobile and supports a human body by gripping. More specifically, the present invention relates to an assist grip that includes a coil spring and is urged along the wall surface of the passenger compartment when not in use to reduce the amount of protrusion into the passenger compartment.

  An assist grip is provided in the automobile compartment for the passenger to support the body. Some of these assist grips are of a fixed type, but in recent years, many of the assist grips have been used along the wall surface of the passenger compartment when not in use and are rotated and gripped during use. This rotation type assist grip has a substantially U-shaped grip body having a longitudinal shape and a recess for hinges on both side bases, a hinge member rotatably held in the recess for hinge, and a hinge member, A coil spring that is interposed between the grip body and urges the hinge member in a direction in which the hinge member is housed in the hinge recess, and a hinge member that is held by the hinge member and engaged with an engagement hole formed in the vehicle body. And a clip to be fixed to.

  In this rotating type assist grip, the hinge member is fixed to the vehicle body by a clip, and when not in use, the grip body is in a state along the wall surface of the passenger compartment due to the urging force of the coil spring, and the amount of protrusion into the passenger compartment is small. ing. In use, the grip body is rotated about the rotation axis of the hinge member against the urging force of the coil spring to protrude into the vehicle interior. By doing so, the grip body can be gripped and the body can be supported.

  For example, in Japanese Patent Laid-Open No. 2006-175990 or Japanese Patent Laid-Open No. 2006-117074, a pair of leg portions each having a through-hole is formed in a hinge member, and left and right walls facing each other of the side wall of the hinge recess of the grip body are formed. In addition, assist grips having through holes have been proposed. According to this assist grip, the through holes formed in the hinge member and the hinge recess are arranged coaxially, and the hinge member is rotatably held in the hinge recess by inserting the metal pin member. Is done.

  However, in the assist grip described above, the end face of the pin member is exposed on the outer surface of the hinge recess. Further, when the grip body is rotated during use, the pin member is visually recognized between the pair of leg portions of the hinge member. Therefore, since the metallic luster of the pin member is visually recognized, there is a problem that the appearance is poor. Furthermore, in the above-described assist grip, in order to prevent the pin member from coming off, the pin member is fixed by being knurled or the like and press-fitted into the through hole of the hinge recess. Therefore, the above-described assist grip has a problem that the press-fitting man-hour of the pin member is large and the assembling workability is poor.

  Therefore, in Special Table 2009-501663, shafts that protrude outward are integrally formed on the pair of leg portions of the hinge member, and shaft holes are formed on the left and right inner surfaces facing each other of the side wall of the hinge recess. And the assist grip which hold | maintained the hinge member to the recessed part for hinges by rotating a shaft part to a shaft hole is proposed. By doing in this way, a pin member becomes unnecessary, and since the end surface of a processus | protrusion is not visually recognized, it looks good.

  JP-T-2009-501663 describes that a spring case containing a coil spring is held between a pair of leg portions of a hinge member so as to perform a return function of the grip body.

Japanese Unexamined Patent Publication No. 2006-175990 JP 2006-117074 A Special table 2009-501663

  However, in the assist grip described in Patent Document 3, since the shaft portion is engaged with the shaft hole while the pair of leg portions of the hinge member is elastically deformed in a direction close to each other, there is a problem that the assembly workability is poor. is there. Moreover, since the shaft portion is made of resin, there is a problem that the strength is lower than that of a metal pin member. Furthermore, there is no specific description regarding the fixing structure of the spring case, and it is assumed that the spring case falls off.

  The present invention has been made in view of such circumstances, and is excellent in workability when assembling the hinge member to the hinge recess, has a good appearance, can reliably prevent the parts from falling off, and has strength in use. It is a problem to be solved to make an assist grip with high.

A feature of the assist grip of the present invention that solves the above problems is that a grip body having a longitudinal shape and having hinge recesses on both side bases, a hinge member rotatably held in the hinge recesses, and a hinge member, A coil spring that is interposed between the grip body and urges the hinge member in a direction in which the hinge member is housed in the hinge recess, and a hinge member that is held by the hinge member and engaged with an engagement hole formed in the vehicle body. An assist grip having a clip to be fixed to
The recess for hinge has bearing holes that do not penetrate the side walls on the inner surfaces of the pair of side walls facing the rotation axis direction of the hinge member, respectively.
The hinge member includes a case recess, a through hole formed in one of the pair of side walls facing the rotation axis direction of the case recess, and a shaft protrusion that protrudes outward from the other of the pair of side walls coaxially with the through hole. And the shaft protrusion is inserted into one bearing hole and the through hole is accommodated in the hinge recess so as to communicate with the other bearing hole,
A pin member that penetrates the through hole and the other bearing hole is inserted into the recess for the case, and the hinge member is arranged so as to be rotatable with respect to the pair of bearing holes by arranging the shaft protrusion and the pin member coaxially. And
A spring case having a shaft portion through which a coil spring is inserted is rotatably held in the recess for the case together with the hinge member. The coil spring has one end engaged with the spring case and the other end engaged with the grip body. Energizing the hinge member through the spring case in the direction in which it is stored in the hinge recess,
Each of the side wall of the spring case and the side wall of the case concave portion includes a slide concave portion and a slide convex portion that guide the sliding movement to the case concave portion of the spring case by engaging each other,
The slide concave portion has a restricting portion that allows the slide convex portion to rotate after the slide convex portion slide-engages and regulates the rotation of the slide convex portion,
When the spring case in which the coil spring is inserted into the shaft portion is stored in the recess for the case, the urging force is stored in the coil spring by the slide convex portion slidingly moving in the slide concave portion. The spring case is fixed to the recess for the case by rotating the part and contacting the restricting part and restricting the rotation of the slide convex part ,
The restricting portion protrudes toward the slide recessed portion in a direction intersecting with the sliding direction of the slide recessed portion and the slide projecting portion, and the slide projecting portion is slid by rotating and being locked to the restricting portion. The movement in the direction of coming out of the recess is restricted .

  According to the assist grip of the present invention, one end of the pin member is inserted into a bearing hole that does not penetrate, and the other end of the pin member is covered with the hinge member and the spring case. The pin member is not visually recognized from the outside and has a good appearance. Moreover, since both ends are supported by the shaft projection protruding from the hinge member and the pin member and the grip body is rotated, sufficient strength can be ensured by using a metal pin member. Furthermore, it is easy to assemble the coil spring, the pin member, and the hinge member, and the number of assembling steps can be reduced.

  Then, one end of the coil spring engages with the spring case and the other end engages with the grip body, so that the hinge member is biased through the spring case in a direction of being accommodated in the recess for hinge. Therefore, the spring case is pressed toward the case recess by the urging force of the coil spring, so that the spring case is prevented from falling off from the case recess.

  Further, the slide convex portion or the slide concave portion is rotated by the urging force after the slide movement, and the rotation of the slide convex portion is regulated by the slide convex portion coming into contact with the regulating portion, and the spring case is regulated by the urging force of the coil spring. Since it is also pressed, it is possible to further prevent the drop-out from the case recess.

  If the restricting portion has a shape that protrudes toward the slide recess in a direction intersecting the sliding direction of the slide recess and the slide protrusion, the slide protrusion rotates and is locked to the restricting portion. The movement in the direction in which the slide convex portion comes out of the slide concave portion is restricted, and the spring case can be more reliably prevented from falling off.

  In order to assemble the assist grip of the present invention, first, the pin member is disposed in the case recess of the hinge member, inserted into the through hole of the case recess, and held so that the tip of the pin member does not protrude outward. Keep it. The hinge member is then housed in the hinge recess. At this time, the axial projection of the hinge member is engaged with one of the bearing holes, and the end of the hinge member on the side of the through hole is located at a position protruding from the hinge recess, and the hinge member is in an oblique state with respect to the hinge recess. To do. The hinge member can be easily accommodated in the hinge recess by pressing the end of the hinge member on the through hole side toward the hinge recess. Thereafter, the pin member is pressed toward the bearing hole and inserted into the other bearing hole of the hinge recess.

  Alternatively, the hinge member may be first housed in the recess for the hinge, and then the pin member may be disposed in the recess for the case and inserted so as to penetrate from the through hole of the recess for the case to the other bearing hole of the recess for the hinge. .

  The clip may be attached to the hinge member in advance or may be attached after the hinge member is stored.

  Next, a spring case with a coil spring inserted through the shaft is inserted into the case recess of the hinge member. At this time, one end of the coil spring engages with the spring case, and the other end engages with a part of the hinge recess of the grip body. Therefore, the coil spring can be wound with the insertion of the spring case, and after insertion, one end of the coil spring urges the spring case toward the recess for the case, so that the spring case is stably brought into the recess for the case. Retained.

  It is preferable that one end of the pin member protrudes from the through hole into the case recess, and the end surface of the pin member faces the end surface of the shaft portion of the spring case. If it does in this way, since movement of a pin member is controlled by an axis part, it can prevent that a pin member slips out from the other bearing hole. Therefore, it is not necessary to fit the pin member into the bearing hole, and the assembly man-hour can be reduced. Moreover, the shape error at the time of molding of each member can be absorbed by the gap between both end faces, and play can be prevented. Furthermore, if the pin member is made of metal, even if the end surface of the pin member and the end surface of the shaft part of the spring case are in sliding contact with each other when the grip body is rotated, different materials are slidably in contact with each other, preventing the generation of abnormal noise. can do.

  The spring case has a two-part structure of a bottomed cylindrical main member having a shaft portion and a sub member fixed to the main member. The sub member has an opening into which the tip of the shaft portion is inserted and a pin member is opened. When the spring case with the coil spring inserted through the shaft portion is stored in the recess for the case, the tip of the pin member protruding from the through hole is guided by the guide groove. Thus, it is preferable to configure so as to face the tip of the shaft portion exposed to the opening. In this way, the coil spring can be easily stored, and the spring case can be easily stored in the case recess. The coil spring can be wound and the urging force can be stored only by inserting the spring case in one direction toward the case recess.

  The spring case has a convex portion that is coaxial with the shaft portion and protrudes on the opposite side of the extending direction of the shaft portion, and the hinge member has a concave portion that does not penetrate the other of the right and left side walls of the concave portion for the case. Preferably they are engaged with each other. By doing so, it is possible to further prevent the spring case from dropping from the case recess.

  The assist grip assembled in this way is fixed to the vehicle body via the hinge member by engaging a clip attached to the hinge member with an attachment hole formed in the vehicle body. Since the hinge member is biased by the coil spring through the spring case in the direction in which the hinge member is housed in the hinge recess, the grip body is in a state along the wall of the passenger compartment, and the amount of protrusion into the passenger compartment is small. When the grip body is rotated during use, the urging force is further stored in the coil spring, so that the occupant can feel that it is supported with an appropriate load, and the feeling of use is excellent.

  In addition to the above-described configuration, the assist grip of the present invention further includes a slide recess and a slide that allow sliding movement to the hinge recess of the spring case by engaging the side wall of the spring case and the sidewall of the hinge recess with each other. Each of the slide recesses is provided with a protrusion, and the slide recess is rotatable after the slide protrusion is slidably engaged, and has a restricting portion for restricting the rotation of the slide protrusion, and a spring case in which the coil spring is inserted into the shaft portion. The urging force is stored in the coil spring when the slide convex portion slides in the slide concave portion when stored in the case concave portion, and the slide convex portion rotates by the urging force after the slide movement, and the slide convex portion becomes the regulating portion. The spring case is fixed to the concave portion for the case by restricting the rotation of the slide convex portion in contact with.

  With this structure, the spring case automatically rotates by a predetermined angle by the urging force stored by the slide convex portion slidingly moving in the slide concave portion during assembly, and the slide convex portion becomes the restricting portion. By abutting, rotation is restricted and the spring case is pressed by the restricting portion. Accordingly, it is possible to reliably prevent the spring case from dropping from the case recess.

  Further, the restricting portion protrudes toward the slide recessed portion in a direction intersecting with the sliding direction of the slide recessed portion and the slide protruding portion, and the slide projecting portion rotates from the slide recessed portion by rotating and contacting the restricting portion. It is preferable that the movement in the direction of pulling out be restricted. By doing in this way, dropping from the case concave portion of the spring case can be more reliably prevented by the restricting portion.

  Hereinafter, embodiments of the present invention will be described specifically by way of examples.

  FIG. 1 is an exploded perspective view of the assist grip of this embodiment. The assist grip includes a resin grip body 1. The grip body 1 has a substantially U-shape consisting of a rod-shaped grip portion and a pair of base portions, and base portions 10 are formed at both ends in the extending direction of the grip portion (hereinafter referred to as the left-right direction).

  FIG. 2 shows the left hinge member 2. A through-hole 24 is formed in the right side wall that is inside the base 10 of the case recess 22. A concave groove-shaped guide portion 25 is formed on the inner peripheral surface of the left side wall where the through hole 24 is not formed, and a concave portion 26 that does not penetrate through the bottom portion of the guide portion 25 and the concave portion 26 gradually toward the end portion. Grooves 27 that are deeper are formed. The guide portion 25 includes a guide rail 251 and a guide rail 252 that is opposed to the guide rail 251 with a space therebetween.

  Here, as shown in an enlarged view in FIG. 3, the guide rails 251 and 252 have a narrowed portion 253 in which the distance between the guide rails 251 and 252 becomes narrow at the center, and the distance between the guide rails 251 and 252 increases toward the outside from the narrowed portion 253. It has a diameter part 254 and a back side enlarged diameter part 255 whose interval increases from the narrowed part 253 toward the back. In addition, a restriction projection 256 that protrudes toward the entrance-side enlarged portion 254 of the guide rail 252 is formed on the entrance-side enlarged portion 254 of one guide rail 251.

  A shaft projection 28 (see FIG. 6) is formed integrally with the left side wall of the hinge member 2 so as to be coaxial with the through hole 24 and project outward. A chamfered portion 280 is formed at the tip of the shaft protrusion 28. A pair of ribs 200 are formed on both sides of the through hole 24 on the outer surface of the right side wall, and a curved chamfered portion 201 is formed on the portion of the outer surface of the right side wall facing the case recess 22. ing. The chamfered portion 201 may be a planar cutout portion.

  The cover member 3 includes a cap portion 30 that is engaged and held with the base portion 20 of the hinge member 2 and a pair of holding plates 31 that protrude from the cap portion 30. A locking claw 300 is formed on the cap 30 and is locked with cover locking portions 202 formed on both sides of the hinge member 2. The pair of holding plates 31 are inserted into a rectangular space formed by the frame portion 21. The cover member 3 is used for permanent fixing after the assist grip is temporarily fixed to the vehicle body panel.

  The hinge member 2 holds a metal clip 4 shown in FIG. The clip 4 is formed by bending a metal plate having spring elasticity into a substantially U-shaped cross section, and an engaging portion having an L-shaped cross section that engages inside the frame portion 21 of the hinge member 2 at each end. 40 is formed, and the bulging part 41 is provided between the engaging part 40 and the U-shaped bent part so as to be elastically deformable in a direction approaching each other and in a direction away from each other. Recessed locking portions 42 that are locked to edges of rectangular holes provided in a vehicle body panel (not shown) are formed. In addition, a locking claw 43 is formed in two at the tip of each bulging portion 41.

  A resin spring case 5 is housed and held in the case recess 22 of the hinge member 2. As shown in FIG. 4, the spring case 5 includes a bottomed cylindrical main member 50 and a sub member 51 integrated with the main member 50, and a coil spring 6 is accommodated therein.

  A shaft portion 52 through which the coil spring 6 is inserted is integrally formed inside the main member 50, and an engagement protrusion 55 is formed on the outer peripheral surface of the main member 50. Further, as shown in FIG. 5, a ring-shaped convex portion 53 and a rectangular guide protrusion 54 are formed on the outer surface of the bottom portion of the main member 50.

  The length of the short side of the guide protrusion 54 is formed equal to the distance from the apex of the restricting protrusion 256 to the guide rail 252, and is formed equal to the distance between the guide rail 251 and the guide rail 252 in the narrowed portion 253.

  The sub member 51 has an opening 56 with which the tip of the shaft portion 52 is engaged, and an engagement hole 57 with which the engagement protrusion 55 is engaged. A fan-shaped notch 58 communicating with the opening 56 is formed on the end surface of the sub member 51.

  To assemble the spring case 5, first, the coil spring 6 is inserted through the shaft portion 52 and inserted into the main member 50. At this time, the short end 60 of the coil spring 6 is inserted into the main member 50, and the other end 61 bent in an L shape projects from the main member 50. Next, while the shaft portion 52 is inserted into the opening 56 of the sub member 51, the engagement protrusion 55 and the engagement hole 57 are engaged to couple the main member 50 and the sub member 51. The other end 61 of the coil spring 6 bent in an L shape protrudes from the gap formed between the main member 50 and the sub member 51 and is movable in the circumferential direction, but one end 60 is the inner wall of the main member 50. , The rotation of the coil spring 6 is restricted.

  Similarly to the left side, the hinge member 2 is accommodated and held rotatably in the right hinge recess 11. However, an oil damper 7 is housed and held in the case recess 22 of the hinge member 2 instead of the spring case 5. The oil damper 7 has a linear rib 70 at the tip of the damper shaft, and an engaging convex portion 71 is formed on the outer peripheral surface of the outer case. The right hinge member 2 has a recess (not shown) that engages with the rib 70 on the inner peripheral surface of the right side wall of the case recess 22, and the damper shaft of the oil damper 7 is hinged by the rib 70 engaging with the recess. 2 is fixed to the recess 22 for the case. Further, the engagement convex portion 71 engages with the damper locking portion 14, whereby the outer case of the oil damper 7 is fixed to the hinge concave portion 11.

  Therefore, when the grip body 1 is rotated with respect to the hinge member 2, the damper shaft of the oil damper 7 is rotated with respect to the outer case, and is rotated so as to give an appropriate rotation resistance.

  Now, when assembling each component configured as described above, first, the metal pin member 8 is disposed in the case recess 22 of the pair of hinge members 2 as shown in FIG. The pin member 8 has a large-diameter portion 80 at the tip, and the large-diameter portion 80 is inserted into the through hole 24 so that the tip is held by the hinge member 2 so as not to protrude outside the hinge member 2. . The hinge member 2 holding the pin member 8 is inserted into the hinge recess 11 of the grip body 1.

  At this time, as shown in FIG. 6, the shaft projection 28 of the hinge member 2 is engaged with one of the bearing holes 12 and the end of the hinge member 2 on the through hole 24 side is located at a position protruding from the hinge recess 11. The hinge member 2 is inclined with respect to the recess 11 for use. And the edge part by the side of the through-hole 24 of the hinge member 2 is pressed toward the recessed part 11 for hinges. Then, the hinge member 2 is guided by the chamfered portion 280 and the chamfered portion 201, so that the hinge member 2 can be easily accommodated in the concave portion 11 for the hinge as shown in FIG. The hole 12 communicates.

  Next, as shown in FIG. 7, the pin member 8 is pressed toward the bearing hole 12 and fitted into the other bearing hole 12. As a result, the pin member 8 has a large-diameter portion 80 at the tip fixed to the other bearing hole 12, and the hinge member 2 is rotatably held in the case recess 22 by the shaft projection 28 and the pin member 8. As shown in FIG. 8, the end of the pin member 8 opposite to the large-diameter portion 80 slightly protrudes into the case recess 22.

  In the present embodiment, the large-diameter portion 80 of the pin member 8 is fitted and fixed to the other bearing hole 12, but the structure is such that the pin member 8 not having the large-diameter portion 80 is simply inserted into the bearing hole 12. You can also

  Subsequently, as shown in FIG. 8, the spring case 5 in which the coil spring 6 is housed and the main member 50 and the sub member 51 are coupled is housed in the case recess 22 of the hinge member 2. At this time, as shown in FIG. 9, the spring case 5 is arranged so that the guide protrusion 54 faces the guide portion 25. First, the guide protrusion 54 does not interfere with the restricting protrusion 256, and the enlarged diameter portion on the entrance side of the guide rail 252. It is inserted so as to be guided to H.254. After the tip of the guide protrusion 54 passes through the narrowed portion 253, the guide protrusion 54 is inserted while being guided by the deeper diameter enlarged portion 255 of the guide rail 251. With the insertion of the guide protrusion 54, the other end 61 of the coil spring 6 is brought into contact with and pressed against the spring locking portion 13, whereby a biasing force is stored in the coil spring 6. Further, the ring-shaped convex portion 53 is guided by the groove portion 27, and the end portion of the pin member 8 is guided by the fan-shaped notch-shaped guide groove 58 at the end opposite to the guide projection 54, while the spring case 5 is stored.

  In the final stage of storing the spring case 5, as shown in FIG. 12, the ring-shaped convex portion 53 is engaged with the concave portion 26, and the distal end surface of the pin member 8 is slightly different from the distal end surface of the shaft portion 52. The spring case 5 is housed in the case recess 22 in a state of being opposed to each other with a gap. At this time, as shown in FIG. 10, the guide protrusion 54 is in contact with the back side enlarged diameter portion 255 of the guide rail 251 and the entrance side enlarged diameter portion 254 of the guide rail 252.

  Next, when the pressing of the spring case 5 is released when the insertion is completed, the guide protrusion 54 is rotated about 10 degrees clockwise by FIG. 10 by the urging force from the one end 60 of the coil spring 6, and as shown in FIG. Then, it abuts against the surface of the restricting projection 256 and abuts against the inner diameter enlarged portion 255 of the guide rail 252 to restrict the rotation.

  Therefore, the spring case 5 is pressed against the hinge member 2 by the urging force of the coil spring 6, the guide protrusion 54 is pressed against the guide rail 252, and the end face of the guide protrusion 54 is locked by the restriction protrusion 256. The spring case 5 is fixed integrally with the hinge member 2.

  The clip 4 is held by the hinge member 2 and then attached to the vehicle body panel in the assist grip of this embodiment assembled in this way. First, the tongue piece portion 23 of the hinge member 2 is inserted between the pair of engaging portions 40 of the clip 4, and the frame portion 21 is penetrated while holding the pair of engaging portions 40 close to each other. Engage with the back side. Thereafter, when the clip 4 is press-fitted into a rectangular hole (not shown) formed in the vehicle body, the pair of bulging portions 41 are elastically deformed so as to approach each other, and when the bulging portions 41 penetrate the rectangular holes, the bulging portions are caused by elastic reaction force. The shape of 41 is restored, the concave locking portion 42 is locked to the edge of the rectangular hole, and the assist grip is temporarily fixed to the vehicle body panel. Thereafter, the pair of holding plates 31 of the cover member 3 are inserted into the frame portion 21 from the back side of the hinge member 2 to prevent the pair of bulged portions 41 of the clip 4 from approaching each other, and the assist grip is attached to the vehicle body panel. The cover member 3 and the hinge member 2 are fixed by the engagement between the locking claw 300 and the cover locking portion 202.

  Therefore, as shown in FIG. 12, the assist grip of this embodiment is in a state in which one end portion of the pin member 8 is fitted into the bearing hole 12 that does not penetrate and the other portion is covered by the hinge member 2 and the spring case 5. For this reason, even when the assist grip is used, the pin member 8 is not visually recognized from the outside, and the appearance is good. In addition, the grip body 1 rotates about the shaft projection 28 and the pin member 8 protruding from the hinge member 2, so that sufficient strength can be secured by using the metal pin member 8. Furthermore, the assembly of the coil spring 6 and the pin member 8 is extremely easy, and the number of assembly steps can be reduced.

  Furthermore, according to the assist grip of the present embodiment, the spring case 5 can be more reliably prevented from falling off due to the interference between the guide protrusion 54 and the restricting protrusion 256.
