Japanese Examined Patent Publication No. 62-36913

  However, although the lever structure described in Patent Document 1 makes it easy to transmit the lifting force to the lever by grasping the gripping portion of the lever, there is a problem that the tip end side of the lever is easily caught on the legs or clothing of the occupant. Therefore, instead of a stick-shaped lever, a lever in which the inner surface of the lever facing the vehicle body is formed along the outer surface of the vehicle body cover has been devised. Thereby, the lever can be brought close to the vehicle body cover so as not to catch the occupant's legs and clothes, but a finger cannot be put between the lever and the vehicle body cover. For this reason, there is a problem that the lever cannot be gripped stably and the operability of the lever is poor.

  The present invention has been made in view of this point, and an object of the present invention is to provide a lever structure for a saddle-ride type vehicle that can stably grip a lever and improve operability.

  The lever structure of the saddle riding type vehicle according to the present invention is a lever structure in which a lever is arranged outside the vehicle body cover below the seat, and the inner side surface of the lever facing the vehicle body side is formed along the outer surface of the vehicle body cover. The lever includes a grip portion that is gripped by at least a fingertip and a raised portion that protrudes from the grip portion to support the palm.

  According to this configuration, since the palm is supported by the raised portion, the lever can be gripped using not only the fingertip but also the entire palm, and the lever can be stably operated. Moreover, since the lever can be brought close to the vehicle body cover by causing the inner surface of the lever to be along the outer surface of the vehicle body cover, it is possible to make it difficult for the occupant's legs and clothing to be caught by the lever.

  In the lever structure of the saddle riding type vehicle according to the present invention, a part of the raised portion is interposed between a palm thumb ball and the vehicle body cover. According to this configuration, even when the lever and the vehicle body cover are brought close to each other, it is possible to prevent the thumb ball from rubbing against the surface of the vehicle body cover during the lever operation.

  Further, in the lever structure of the saddle riding type vehicle according to the present invention, the raised portion has a stepped portion recessed toward the vehicle body side along the thumb ball of the palm in a state where the lever is gripped. According to this configuration, the lever is easily gripped by fitting so that the thumb ball is wrapped around the outer surface of the stepped portion. Further, it becomes easy to press the thumb ball against the raised portion, and the gripping position of the lever is stabilized and the shift of the gripping position is restricted.

  Further, in the lever structure of the saddle riding type vehicle according to the present invention, the raised portion has a regulating surface that comes into contact with the distal end side or the proximal end side of the palm thumb ball when the lever is gripped. According to this configuration, since the deviation of the gripping position of the lever toward the distal end side or the proximal end side is restricted, it is difficult for the hand to come off the lever during the lever operation, and the operability of the lever can be improved.

  In the lever structure for a saddle-ride type vehicle according to the present invention, the lever has a protruding portion that protrudes in a direction opposite to the raised portion at a tip portion of the grip portion. According to this configuration, since the position of the hand is determined by the raised portion and the protruding portion, it is difficult for the hand to come off the lever during the lever operation, and the operability of the lever can be improved. Further, since the tip of the lever is widened up and down as much as the protrusion is provided, it is possible to make it difficult for the occupant's legs and clothes to be caught on the tip of the lever.

  In the lever structure of the saddle riding type vehicle according to the present invention, the lever operates a parking brake device that maintains a braking state during parking. According to this configuration, a stable operation is possible even in a parking brake device having a large force for lever operation.

  According to the lever structure of the straddle-type vehicle of the present invention, by providing the grip portion with a raised portion that supports the palm, the lever can be stably gripped and the operability can be improved.

FIG. 1 is a left side view of the motorcycle according to the present embodiment. FIG. 2 is a perspective view of the periphery of the lever according to the present embodiment. In the following drawings, the front of the vehicle body is indicated by an arrow FR, and the rear of the vehicle body is indicated by an arrow RE.

  As shown in FIG. 1, a scooter type motorcycle 1 is configured by attaching various covers as a vehicle body exterior to a vehicle body frame (not shown) made of steel or aluminum alloy. The motorcycle 1 is provided with a front cowl 21 so as to protect the front of the rider, and a leg shield 22 is provided on the back side of the front cowl 21 for protecting the leg of the rider. A step board 23 extends rearward from the lower end of the leg shield 22, and a rider seat 31 and a seat cowl 24 are provided below the pillion seat 32 behind the step board 23.

  In the scooter type motorcycle 1, a footrest space in which a leg portion of an occupant is placed in front of the rider seat 31 is formed by the leg shield 22 and the step board 23. The footrest space is divided into left and right by a center console 25 located at the center in the vehicle width direction. The center console 25 extends in the front-rear direction so as to connect the leg shield 22 and the seat cowl 24. By placing the rider's legs in the left and right footrest space so as to straddle the center console 25, the left and right legs are protected from running wind and the like.

  On the front side of the vehicle body, a pair of front forks 41 are supported so as to be able to swing left and right via a steering shaft (not shown) provided on a head pipe (not shown). Above the pair of front forks 41, a handle bar 43 for steering the front wheels 42 is provided. The handle bar 43 on the left side of the vehicle body is provided with a brake lever 44 for the rear wheel 56, and the handle bar 43 on the right side of the vehicle body is provided with a brake lever (not shown) for the front wheel 42. A front fender 45 is installed at the lower part of the pair of front forks 41 so as to rotatably support the front wheel 42 and cover the upper part of the front wheel 42.

  The front wheel 42 is provided with a brake caliper 47 that sandwiches the brake disc 46 and the brake disc 46. A headlamp 48 is provided in front of the front cowl 21, and a windscreen 26 for windbreak is provided above the headlamp 48. A rider seat 31 and a pillion seat 32 are connected to the seat cowl 24 at the rear of the center console 25 at the center of the vehicle body. A luggage space (not shown) for storing a helmet or the like is provided on the back side of the rider seat 31.

  As shown in FIG. 2, a parking brake lever 33 is provided below the rider seat 31. The occupant can lock and release the parking brake by pulling the lever 33 upward in the sitting posture. The lever 33 is formed in a thin wall and is disposed so as to be accommodated in a recess 241 formed in the seat cowl 24. For this reason, since the protrusion of the lever 33 from the outer surface of the seat cowl 24 is suppressed, the occupant's legs and clothes can be restrained. The lever 33 is formed with a raised portion 34 that supports the palm. The raised portion 34 grips the lever 33 using not only the fingertip but also the entire palm, so that the operability of the lever 33 is improved. Details of the lever 33 will be described later.

  Returning to FIG. 1, a passenger's grab bar 51 is provided in the vicinity of the pillion seat 32 on the side of the seat cowl 24. A tail lamp 52 and a rear fender 53 are provided at the rear portion of the seat cowl 24. An engine (not shown) mounted on a vehicle body frame (not shown) is housed inside the seat cowl 24.

  A transmission case 54 that functions as a swing arm is connected to the lower side of the rear part of the vehicle body so as to be swingable in the vertical direction. Is attached. Inside the transmission case 54 is housed a belt-type continuously variable transmission in which a drive belt is stretched between a drive pulley on the engine side and a driven pulley on the rear wheel 56 side. The transmission is shifted by changing the winding radius of the drive belt. The rear wheel 56 is rotationally driven by transmission of power from the engine via a drive belt.

  The engine is suspended from the body frame in a state where the cylinder is tilted in a substantially horizontal direction with the cylinder facing forward. Air is taken into the engine via an intake pipe (not shown), and air and fuel are mixed by a fuel injection device and supplied to the combustion chamber. Exhaust gas after combustion in the combustion chamber is exhausted from the muffler 57 through an exhaust pipe (not shown) extending below the engine. Heat from each part of the engine is cooled by a radiator (not shown) disposed inside the front cowl 21 on the front side of the vehicle body.

  The lever periphery will be described in detail with reference to FIGS. FIG. 3 is a left side view around the lever according to the present embodiment. FIG. 4 is a view in which the rider seat and the seat cowl are omitted from FIG.

  As shown in FIGS. 3 and 4, the parking brake lever 33 is arranged in a region immediately below the rider seat 31 so that the lever can be operated in a seated posture state. Below the rider seat 31, a seat cowl 24 is recessed toward the luggage space, and a recess 241 in which the lever 33 is disposed is formed. Thus, the parking brake device exposes the lever 33 in the recess 241 of the seat cowl 24 and houses the drive mechanism 37 coupled to the lever 33 in the seat cowl 24.

  In the drive mechanism 37, an arm 373 provided with a lever 33 is rotatably supported via a rotation shaft 372 on an arm bracket 371 fixed to a seat frame 10 which is a part of a vehicle body frame (not shown). . The arm 373 is a substantially crank-shaped metal plate. A substantially half portion on one end side is accommodated in the seat cowl 24, and a substantially half portion on the other end side is exposed in the recess 241. One end of an arm 373 in the seat cowl 24 is rotatably supported by an arm bracket 371, and a lever 33 is attached to the other end of the arm 373 outside the seat cowl 24. Therefore, the lever 33 is swung up and down with one end of the arm 373 in the seat cowl 24 as a fulcrum.

  A parking brake cable 374 is fixed to the arm 373. The cable 374 extends toward the lock mechanism of the parking brake device, and the locking and unlocking of the lock mechanism is switched by the swinging operation of the lever 33. In the present embodiment, the parking brake is locked by raising the lever 33. Further, the parking brake is unlocked by further lifting the lever 33 to the maximum position, and when the lever 33 is released, the lever 33 returns to the initial position by the action of a biasing means (not shown).

  The lever 33 is formed in a substantially Z shape in side view, with a raised portion 34 protruding upward on the proximal end side of the grip portion 35 extending in the longitudinal direction of the vehicle body, and a protrusion 36 protruding downward on the distal end side of the grip portion 35. ing. The lever 33 is formed thin in the vehicle width direction and is disposed so as to be accommodated in the recess 241. The lever 33 is formed to follow the streamline shape of the seat cowl 24. Specifically, the outer surface shape of the lever 33 is formed so as to be continuous with the ridgeline 242 that forms the outer surface shape of the seat cowl 24. Therefore, the lever 33 is formed so as to be seen as a part of the seat cowl 24 in a side view, and has a design that does not give an uncomfortable appearance.

  An inner side surface 331 of the lever facing the vehicle body in a cross-sectional view is formed along the outer surface 243 of the seat cowl 24 in the recess 241 (see FIG. 6). With this configuration, the lever 33 is brought close to the outer surface 243 of the seat cowl 24, and the protrusion of the outer surface 332 of the lever 33 is suppressed, so that the lever 33 is difficult to be caught by the leg portion when riding. On the other hand, the lever 33 is disposed along the outer surface 243 of the seat cowl 24, so that the fingertip does not enter the gap between the inner surface 331 of the lever 33 and the outer surface 243 of the seat cowl 24. It cannot be grasped.

  Therefore, in the lever 33 of the present embodiment, the grip 35 is widened in the vertical direction, and the feeling of close contact with the lever 33 is improved without increasing the thickness of the lever 33. As a result, the depth of the recess 241 of the seat cowl 24 can be reduced by an amount corresponding to the reduction in the thickness of the lever 33, and the decrease in the capacity of the luggage space due to the recess 241 can be minimized. As described above, even in the lever structure in which the lever 33 is disposed along the outer surface 243 of the seat cowl 24, a sufficient luggage space is secured inside the seat cowl 24 while leaving the lever 33 easy to grasp.

  The raised portion 34 is raised in a mountain shape upward on the proximal end side of the grip portion 35. The raised portion 34 is formed so as to contact the thumb ball at the base of the thumb and support the palm in a state where the lever 33 is gripped. The raised portion 34 is formed with a regulating surface 341 that is inclined so as to become higher toward the proximal end side of the grip portion 35. The regulation surface 341 regulates displacement of the thumb ball toward the proximal end side of the grip portion 35 by contacting at least a part (tip side or proximal side) of the thumb ball 30 with the lever 33 being gripped. doing.

  The raised portion 34 is formed with a stepped portion 342 that is recessed toward the vehicle body (see FIG. 6). The step portion 342 has an outer surface shape that follows the thumb ball 30 in a state where the lever 33 is gripped. Since the thumb ball 30 forms a bulge at the base of the thumb, the lever 33 is easily gripped by fitting so that the thumb ball 30 is wrapped around the outer surface of the stepped portion 342. In addition, it becomes easy to press the thumb ball 30 against the raised portion 34, the gripping position of the lever 33 is stabilized, and the shift of the gripping position is restricted.

  A part of the raised portion 34 is interposed between the thumb ball 30 and the outer surface 243 of the seat cowl 24 (see FIG. 6). Therefore, even if the lever 33 and the seat cowl 24 are brought close to each other, the thumb ball 30 does not come into contact with the outer surface 243 of the seat cowl 24, and the thumb ball 30 contacts the outer surface 243 of the seat cowl 24 when the lever 33 is operated. There is no rubbing.

  The protruding portion 36 protrudes in a mountain shape downward on the distal end side of the grip portion 35. The protrusion 36 is in contact with the side surface of the index finger in a state where the lever 33 is gripped, and restricts the displacement of the hand toward the distal end side of the gripper 35. Thus, since the position of the hand is determined by the raised portion 34, the protrusion 36, the regulating surface 341, and the stepped portion 342, the positional displacement of the hand in the front-rear direction is restricted, and the hand is difficult to come off from the lever 33 during the lever operation. Thus, the operability of the lever 33 is improved. In the lever 33 according to the present embodiment, the positional deviation of the hand is regulated by the raised portion 34, the protruding portion 36, the regulating surface 341, and the stepped portion 342, but even if the positional deviation of the hand is regulated by any of them. Good. For example, the lever 33 may be provided with only the raised portion 34 or the protruding portion 36, and only the positional deviation toward the rear or the front may be restricted.

  Further, the lever 33 is widened up and down as much as the protrusion 36 is provided, so that the occupant's legs, clothing, etc. are caught on the distal end side of the lever 33 compared to the case where the distal end side of the lever 33 is thin. It becomes difficult. Furthermore, in the top view, the outer surface 332 of the lever 33 is formed along the outer surface 243 of the seat cowl 24, and has a design that does not cause a sense of incongruity on the outer ring (see FIG. 7). At this time, since the distal end side of the lever 33 is formed following the outer surface 243 of the seat cowl 24, it is difficult for leg portions, clothing, etc. to be caught by the lever 33.

  The lever operation will be described in detail with reference to FIGS. FIG. 5 is an explanatory diagram of lever operation according to the present embodiment. FIG. 6 is a sectional view around the lever according to the present embodiment. FIG. 7 is a top view of the periphery of the lever according to the present embodiment. FIG. 8 is an explanatory diagram of lever positions according to the present embodiment. FIG. 5A shows a parking brake released state, and FIG. 5B shows a parking brake locked state. 6A is a cross-sectional view taken along line XX in FIG. 5A, and FIG. 6B is a cross-sectional view taken along line YY in FIG. 5A. 5 to 7, the passenger's hand is indicated by a two-dot chain line for convenience of explanation.

  As shown in FIG. 5A, when the occupant grips the lever 33, the upper surface of the grip portion 35 is pressed by the belly of the thumb, and the lower surface of the grip portion 35 is hooked by the remaining four fingertips. At this time, the thumb ball 30 (see FIG. 6) at the base of the thumb is supported by the raised portion 34 formed on the proximal end side of the grip portion 35, and the projection 36 is formed on the distal end side of the grip portion 35. Touched from the front. The positional displacement of the thumb ball 30 to the rear is restricted by the restriction surface 341 of the raised portion 34, and the positional deviation of the remaining four fingertips is restricted to the front by the projection 36. The raised portion 34 and the projecting portion 36 determine the position of the hand of the lever 33 and make it difficult to remove the hand from the lever 33 during the lever operation.

  6A and 6B, the palm thumb ball 30 is supported by the step 342 of the raised portion 34. The outer surface of the step portion 342 is formed along the bulge of the thumb ball 30, and the thumb ball 30 is encased in the outer surface of the step portion 342. As a result, the bulge of the thumb ball 30 fits into the raised portion 34 and the gripping position of the lever 33 is stabilized. The range from the thumb to the thumb ball 30 is strongly pressed against the upper surface of the lever 33, and the lever 33 is gripped using the thumb ball 30 as well as the thumb. In addition, the grip portion 35 is formed wide in the vertical direction so as to eliminate a gap between the lever 33 and the palm. Therefore, the lever 33 is gripped not only by the fingertip but also by the entire palm.

  Also in the top view shown in FIG. 7, the palm thumb ball 30 fits the step portion 342. Since the thumb ball 30 fits in the step 342 of the lever 33 in a cross-sectional view and a top view, the swelling of the thumb ball 30 does not interfere with the grip of the lever 33, and conversely, the grip position of the lever 33 is easily determined. It has become. Part of the raised portion 34 is interposed between the thumb ball 30 and the seat cowl 24 to prevent contact between the thumb ball 30 and the seat cowl 24.

  Then, the lever 33 in the lower position shown in FIG. 5A is pulled up to the upper position as shown in FIG. 5B. The lever 33 rotates (rotates) about the rotating shaft 372 of the drive mechanism 37 to actuate (lock) the parking brake device (see FIG. 4). At this time, a force acts on the distal end side of the lever 33 in the direction of pulling up from below with a fingertip, and a force pressed by the thumb ball 30 acts backward on the proximal end side of the lever 33. During the lever operation, the index finger is hooked on the protrusion 36 on the distal end side of the lever 33 and the positional deviation of the forward hand is restricted, and on the proximal end side of the lever 33, the thumb ball 30 is connected to the raised portion 34. It is pushed back by the regulating surface 341 and the rearward displacement is regulated. As described above, the positional deviation of the hand in the front-rear direction of the lever operation is prevented, the hand is hardly detached from the lever 33, and the operability of the lever 33 is improved.

  As shown in FIG. 8, the lever 33 is operated between a lower position P1 before the operation and an upper position P3 after the operation, with a horizontal position P2 at which the grip portion 35 is horizontal. That is, since the operation range of the lever 33 is set across the horizontal position P2, the angle at which the wrist is bent when the lever 33 is operated is not biased upward or downward. Therefore, the lever 33 can be operated using a wide range of movement of the wrist in the vertical direction, and the operability of the lever 33 is improved.

  As described above, according to the present embodiment, since the palm is supported by the raised portion 34, the lever 33 can be gripped using not only the fingertip but also the entire palm, and the lever 33 can be operated stably. be able to. In addition, the positional deviation of the hand in the front-rear direction is restricted by the raised portion 34 on the proximal end side of the gripping portion 35 and the protrusion portion 36 on the distal end side of the gripping portion 35, and it is difficult for the hand to come off the lever 33 during the lever operation. ing. Further, since the lever 33 is formed along the outer surface shape of the seat cowl 24, the design is good, and the legs and clothes of the occupant are not easily caught on the lever 33.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited.
