Description

  The present invention relates to a grip mounted on a motorcycle such as a passenger grip.

  A grip for a passenger of a motorcycle to grip is generally a metal molded with a resin, or a grip formed only with a metal. When a metal is molded with a resin, since the metal and the resin are integrally formed, it is difficult to recycle, and there is a risk that the resin will crack due to the difference in thermal expansion coefficient between the metal and the resin. In the case of forming only with metal, the weight is increased, painting is required, and the cost is increased. In addition, there is one in which a grip is formed of a hard synthetic resin and a gripping comfort is improved by disposing a flexible filling member in a recess provided to prevent sink marks (Patent Document 1).

  As shown in FIG. 6, the locking structure including the locking groove 58 and the locking claw 70 is configured so that the locking claw 70 provided on the second cover 38 is located inside the upper opening edge 50 of the first cover 36. By passing through the locking groove 58 of the first cover 36 through the first cover 36 and the second cover 38, the first cover 36 and the second cover 38 are polymerized without being relatively displaced.

  Next, a method for assembling the grip 30 will be described. First, the metal core 34 in FIG. 5A is placed on the back surface of the first cover 36, the mounting piece 42 of the metal core 34 is aligned with the upper concave portion 48, and the boss 54 of the first cover 36 is moved to the metal core 34. Fit into the through hole 40a. Thereby, the metal core 34 is positioned. As shown in FIG. 8, a slight radial gap S <b> 1 is generated between the through hole 40 a of the core metal 34 and the boss 54 of the first cover 36, and the outer edge of the core metal 34 and both covers 36. , 38 are also formed between the opening edges 50 and 64. As a result, the difference in coefficient of thermal expansion between the cored bar 34 and the covers 36 and 38 is absorbed, and the covers 36 and 38 are prevented from being damaged due to thermal deformation. Furthermore, since the dimensional error of the covers 36 and 38 is also absorbed, the assemblability of the grip 30 is improved.

  Subsequently, the second cover 38 is put on the first cover 36 so that the locking claw 70 of the second cover 38 shown in FIG. 6 is locked in the locking groove 58 of the first cover 36. Since the first and second covers 36 and 38 are made of resin and have elasticity, when the second cover 38 is pressed against the first cover 36, both the covers 36 and 38 are deformed, and the locking claw 70. Enters the locking groove 58. As a result, positioning in the direction along the opening edges 50 and 64 of both covers 36 and 38 is performed in a state where the opening edges 50 and 64 of the first and second covers 36 and 38 are overlapped with each other. In this state, polymerization is performed so that the opening edge 50 of the first cover 36 is placed on the outside of the opening edge 64 of the second cover 38.

  In the state where the opening edge portions 50 and 64 are overlapped with each other in this manner, as shown in FIG. 8, the connecting member 72 is inserted into the bolt insertion hole 68 a of the second cover 38 through the washer 74 and the collar 76, The metal core 34, the first cover 36, and the second cover 38 are firmly connected by being screwed into the insert nut 56 fitted to the boss 54 of the first cover 36. In this way, the connecting member 72 is inserted from below, and the connecting member 72 is not exposed to the outer surface of the upper first cover 36, so the appearance is not impaired. Further, in this embodiment, a recessed portion 68b that is recessed upward is formed around the bolt insertion hole 68a in the lower second cover 38, and the head of the connecting member 72 and the washer 74 are connected to the side of the vehicle body. It is difficult to see from. Furthermore, since the connection part by the connection member 72 is provided in the vicinity of both ends in the longitudinal direction of the grip part 30a of the grip 30, the degree of freedom of the shape of the center grip part 30a is increased, and the grip part 30 can be easily gripped.

  In a state where the core metal 34, the first cover 36 and the second cover 38 are connected, the first main surface F 1 of the main body piece 40 of the core metal 34 contacts the tip 52 a of the upper rib 52 of the first cover 36. The second main surface F2 of the main body piece 40 of the metal core 34 and the tip 66a of the lower rib 66 of the second cover 38 come into contact with each other, so that the metal core 34 is between the first and second covers 36, 38. To be sandwiched.

  Next, an example of a method for attaching the grip 30 to the vehicle body will be described. As shown in FIG. 9 which is a side view, the grip 30 is fastened together with a fastening member 80 such as a bolt together with a tail cover 32 to a bracket 78 fixed to the rear frame 4.

The collar 84 is fitted into the bolt insertion hole 42 a of the attachment piece 42 of the grip 30 and the through hole 82 a of the grommet 82, and the fastening member 80 is inserted into the collar 84 and fixed to the bracket 78. The grip 30 is attached to the vehicle body by being screwed to the weld nut 86. A washer 88 and a damper 90 made of an elastic member are interposed between the head of the fastening member 80 and the mounting piece 42. Since the passenger seat 24 (FIG. 2) is mounted above the mounting portion, the mounting portion cannot be seen from the outside. The attachment method of the grip 30 is not limited to this, and for example, the grip 30 may be attached directly to the rear frame 4 without using the grommet 82, the washer 88, the damper 90, and the like.

  In the above configuration, the cored bar 34, which is a portion attached to the vehicle body in the grip 30 shown in FIGS. This eliminates the need to unnecessarily increase the size of the grip 30 or provide a reinforcing material, thereby reducing the size and simplifying the manufacturing cost. Further, since the metal cored bar 34 and the first and second covers 36 and 38 made of resin are separate bodies, each member can be attached and detached for easy recycling. Since the insert nut 56 (FIG. 5A) provided in the first cover 36 is press-fitted, it can also be removed, so that the recyclability is not impaired.

  Further, since both the covers 36 and 38 and the cored bar 34 are connected by the connecting member 72 shown in FIG. 8, the both covers 36 and 38 and the cored bar 34 are firmly connected, and the connecting member 72 is also connected. It is easily disassembled by removing and improves recyclability.

  Further, since the connecting member 72 is inserted from below and no through hole is formed in the upper surface of the first cover 36 located above, rainwater and the like can be prevented from entering the grip 30 and the appearance is also impaired. I can't.

  Since the first cover 36 is located above the second cover 38 and the upper opening edge 50 of the first cover is placed outside the lower opening edge 64 of the second cover 38, The upper opening edge portion 50 located at the outer side becomes the outer side, and this also prevents rainwater and the like from entering the covers 36 and 38.

  The opening edges 50, 64 of the first and second covers 36, 38 are locked by a locking claw 70 provided in the second cover 38 in a locking groove 58 provided in the first cover 36. As a result, the displacement between the covers 36 and 38 is prevented.

  The cored bar 34 has a plate-like flat main body piece 40, and an upper rib 52 and a lower rib 66 that contact the flat main body piece 40 stand on the inner surfaces of the first and second covers 36 and 38, respectively. Since the cored bar 34, the first cover 36, and the second cover 38 are connected, the cored bar 34 is stably held in a sandwich shape between the first and second covers 36, 38. Is done. As a result, rattling between the cored bar 34 and the covers 36 and 38 is eliminated, so that even when the motorcycle is running, a collision sound between the cored bar 34 and the covers 36 and 38 due to vibration is suppressed. . Furthermore, since the ribs 52 and 66 are erected on the inner surfaces of the covers 36 and 38, the strength of the covers can be increased.

  In addition to the passenger grip, the present invention can also be applied to a vehicle body pulling grip 100 shown by a two-dot chain line in FIG. 1 that is gripped when raising the center stand and pulls up the rear portion of the vehicle body.

  As described above, the preferred embodiments of the present invention have been described with reference to the drawings, but various additions, modifications, or deletions can be made without departing from the spirit of the present invention. For example, in this embodiment, the locking groove 58 is provided in the first cover 36 and the locking claw 70 is provided in the second cover 38, but the reverse may be possible. Further, in this embodiment, the insert nut 56 is press-fitted into the boss 54 of the first cover 36 and the core metal 34 and the first and second covers 36 and 38 are connected by the connecting member 72 such as a bolt.
