TECHNICAL FIELD OF THE INVENTION
The present invention relates to a motorcycle seat structure.
[0002]
[Prior art]
Conventionally, an invention relating to a tandem seat used in a motorcycle has been proposed (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-2002-145143 (FIG. 7)
[0004]
FIG. 24 is a reprint of FIG. 7 of Patent Document 1, and FIG. 24 (F) shows a seat arrangement when two people are riding, and FIG. 24 (E) shows a seat arrangement when one person is riding.
[0005]
[Problems to be solved by the invention]
Conventionally, it has been known that the passenger seat 3R is erected and provided to a driver's backrest. However, as is clear from FIG. 7E, there is no technical idea that the space behind the passenger seat 3R is used as a carrier when a single passenger is riding. Even if the luggage is placed in the rear space, there is no hook to hook the string.
[0006]
In a motorcycle with a small luggage loading area, it is desired to secure a luggage carrier on which luggage can be stably loaded.
Therefore, an object of the present invention is to provide a seat structure capable of securing a cargo bed when riding alone in a two-seater motorcycle.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, claim 1 is a motorcycle including a driver seat where a driver sits and a passenger seat where a passenger can sit,
The passenger seat is a passenger seat and a seat back that can be used for a driver's backrest by standing up when riding alone, and is provided with a hook on a back surface of which a string or the like can be hung when standing up.
[0008]
A hook that allows a string to be hung on the back when standing up is provided, so luggage can be placed in the rear space when riding alone, and this luggage can be hooked directly or indirectly by using a string, etc. . The hooks become invisible when the passenger seat and seat back are leveled, so that the appearance is not impaired.
Therefore, a stable load can be loaded, and the motorcycle of the present invention can carry a larger amount of load.
[0009]
According to a second aspect of the present invention, the motorcycle is provided with a carrier that appears when the passenger seat and the seat back are erected.
Providing the loading platform behind the driver's seat enables stable loading of luggage when a single passenger is riding.
[0010]
According to a third aspect of the present invention, the motorcycle is provided with an inverted U-shaped grab rail at a side position of the carrier.
The grab rail, which serves as a gripping member for a fellow passenger when a two-passenger rides, is formed in an inverted U-shape so that a string or rope can be passed through, and luggage can be easily fixed with the string or rope.
[0011]
According to a fourth aspect, the grab rail is attached to the vehicle body frame below the carrier.
By hiding the grab rail mounting portion under the cargo bed, the grab rail mounting portion becomes invisible, and the appearance around the grab rail can be enhanced.
[0012]
A fifth aspect of the present invention is characterized in that a storage case extending in the front-rear direction of the vehicle body is mounted under a rear frame that supports the loading platform, and a flange portion projects forward from the storage case.
Small items that are too small to be placed on the bed can be stored, and the loading capacity can be further increased by the storage box and the bed.
In addition, the flange portion projecting forward from the storage compartment can cover an apparatus such as an air secondary control valve, and can promote a reduction in the size of the vehicle body cover.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of reference numerals.
In the present embodiment, a low-floor type vehicle will be described by taking a scooter type vehicle as an example. However, the low-floor type vehicle may be any of a two-wheeled vehicle, a three-wheeled vehicle, and a four-wheeled vehicle. In short, the low-floor vehicle includes front and rear wheels in front and behind the body frame, and the main body frame extends rearward from the head pipe. Any type of vehicle may be used as long as the frame is V-shaped or U-shaped in side view so that the driver can easily straddle the main frame.
[0014]
FIG. 1 is a side view of a scooter type vehicle according to the present invention. In a scooter type vehicle 10, a steering handle 13 is attached to a head pipe 12 at a front portion of a body frame 11 so as to be steerable, and a front fork connected to the operation handle 13. The basic structure is to attach the front wheel 15 and the front fender 16 to the front wheel 14.
Then, a separate frame 18 is attached to the body frame 11, a headlight 19, a direction indicator light 21 and the like are attached to the separate frame 18, a step 22 is attached to the down tube 17, and a power unit is attached to the rear of the body frame 11. A rear wheel 24 is mounted at the rear of the power unit 23, and a driver's seat 25 is provided diagonally upward toward the front of the rear wheel 24, and a passenger seat / seat back 26 is provided above the rear wheel 24. It is a light vehicle that can be used by two people.
[0015]
In the figure, 27 is a handle post cover, 28 is a side cover, 29 is a rear cushion, 31 is a stand, and 32 is a grab rail.
[0016]
FIG. 2 is a side view of a scooter-type vehicle according to the present invention, which has been changed to a single-seat specification. The basic configuration is the same as that of FIG. This indicates that the driver 26 has been turned upright and the driver M has changed the backrest, that is, the driver M has changed the pattern to the seatback. It also indicates that luggage 33 such as a tent is loaded on the front of the separate frame 18.
[0017]
Further, not only the steering handle 13 and the grab rail 32 but also the separate frame 18, the down tube 17, the lower pipe 34 and the rear frame 35 extending from the down tube 17 are exposed.
[0018]
In a conventional scooter-type vehicle, it is common to cover the body frame with a body cover so that most of the body frame is not exposed. On the other hand, according to the present invention, most of the body frame is exposed so as to exhibit an unprecedented appearance feature.
[0019]
FIG. 3 is a perspective view of the steps adopted in the present invention. The right step 22R (R is a suffix indicating right; the same applies hereinafter) on which the driver places the right foot is a receiving plate 36 and this receiving plate 36. And a pipe 38 extending around the edge of the receiving plate 36, and a rubber plate 39 mounted on the upper surface of the receiving plate 36. The rubber plate 39 may be a soft resin plate.
The left step 22L for placing the left foot (L is a suffix indicating the left; the same applies hereinafter) is the same structure as the right step 22R, and the reference numerals are diverted, and the description is omitted.
[0020]
FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 3, and the rubber plate 39 is provided with a so-called cracked bulb-shaped latching projection 41... It shows that it can be detachably attached to the plate 36.
[0021]
Conventionally, in a flat plate type step, there is an object formed by aluminum die casting or the like. Die casting is often preferred in terms of appearance, but cost reduction is expected for vehicles of medium size or smaller.
[0022]
For this reason, a step of assembling a steel plate by welding is also employed, but is inferior to an aluminum die-casting step in weight and appearance.
In this regard, in step 22 (22L, 22R) according to the present invention, since the pipe 38 is wrapped around the edge of the receiving plate 36, the pipe 38 serves as a reinforcing material for the receiving plate 36, and the thickness and weight of the receiving plate 36 can be reduced. I can do it. As a result, it is possible to reduce the weight and cost as compared with the die-casting step while maintaining the appearance of the steps 22L and 22R.
[0023]
In addition, since the step 22 according to the present invention can be manufactured by cutting, bending, performing plastic working such as drawing, and welding the steel material, a die and a die casting machine are unnecessary, and the manufacturing cost is lower than that of the die casting step. Can be reduced.
[0024]
FIG. 5 is an exploded view of the body frame of the scooter-type vehicle according to the present invention. The body frame 11 has a main frame 43 extending from a head pipe 12 and having a V-shape or a U-shape in a side view. A rear frame 35 that constitutes a rear portion or extends rearward, a down tube 17 that hangs down from the head pipe 12, a lower pipe 34 that extends substantially horizontally following the down tube 17, and rises from the rear end of the lower pipe 34. It comprises a center frame 44 and a stay 45 connecting the center frame 44 and the rear frame 35. The lower pipe 34 is provided with cover stopper plates 46, 46.

[0026]
The separate frame 18 includes a load receiving pipe 47 on the front upper surface, a lamp support bracket 48 and a loading hook 49 on the front lower surface, cover cover plates 51 and 51 on the lower surface, and a hole 52 on the front upper surface. And a U-shaped bracket 54 on the rear lower surface.
[0027]
On the other hand, a front plate 57 having holes 56, 56 is provided on the front surface of the head pipe 12, and a rear plate 59 having holes 58 is provided on the front upper surface of the rear frame 35. The rear plate 59 is disposed near the joint 55 between the main frame 43 and the rear frame 35. The connecting portion 55 is an assembled portion of one main frame 43 and two rear frames 35, and has high rigidity. Providing the rear plate 59 in the vicinity (in the embodiment, rearward) of such a high rigidity coupling portion 55 is advantageous in strength in supporting the separate bracket 18.
[0028]
Then, the separate frame 18 can be integrated with the head pipe 12 and the main frame 43 by bolting the bracket 53 to the front plate 57 and bolting the U-shaped bracket 54 to the rear plate 59. The configuration after integration will be described with reference to FIG.
[0029]
FIG. 6 is a view for explaining the operation of the separate frame according to the present invention. The separate frame 18 is a pipe frame having a U-shape in a plan view. This is a useful frame to which the illuminating light 19 can be attached, the meter unit 61 can be attached to the load receiving pipe 47, and the parking brake levers 63 can be attached to the right of the bracket 53 via the stay 62.
[0030]
Also, for example, vehicle parts such as the direction indicator light 21, the headlight 19, the meter unit 61, the parking brake levers 63, and the like are previously mounted on the separate frame 18 (this is referred to as a small assembly). 6) to the head pipe 12 and the main frame 43 shown in FIG. 5, it is also possible to shorten the required assembly time on the assembly line.
[0031]
FIG. 7 is a side view of the body frame of the scooter-type vehicle according to the present invention, in which the separate frame 18 is attached to the head pipe 12 and the rear frame 35, and the center cover portion 64 integrally having the handle post cover 27 is covered. The side cover 28 is attached between the separate frame 18 and the lower pipe 34 with bolts 65..., And the step 22L is attached to the lower pipe 34.
[0032]
As shown in the figure, the front surface of the handle post cover 27 has a flat surface, and a structure that allows sufficient space for the loading platform in front is adopted.
In addition, a shelf 27a which is one step lower is formed at the rear and upper part of the handle post cover 27, and a combination lock device 70 (detailed structure will be described later) is attached to the shelf 27.
[0033]
FIG. 8 is a sectional view taken along line 8-8 of FIG. 7, in which the center cover 64 is attached to the cover fixing plates 66, 66 attached to the separate frame 18 by bolts 67, 67, and the bolts 65 are attached to the cover fixing plates 51, 51. , 65 indicate that the side covers 28, 28 were attached.
[0034]
If the center cover portion 64 and the side covers 28 are to be bolted to the main frame 43, a large-scale cover mounting bracket is required.
[0035]
In this regard, in the present invention, separate frames 18, 18 (the separate frame 18 is one, but two symbols are described for convenience) are disposed above the left and right lower pipes 34, 34. It is characterized in that the center cover portion 64 and the side covers 28, 28 are attached by using the body frames 18, 18 skillfully.
[0036]
As a result, the separate frames 18, 18 can be utilized for fixing luggage and the like. Further, since the center cover portion 64 and the side covers 28, 28 (referred to as vehicle body covers) are disposed inside the separate frames 18, 18, and the left and right lower pipes 34, 34, the vehicle body cover can be made compact as a whole. As a result, the weight and cost of the body cover can be reduced.
[0037]
Furthermore, since the box-shaped vehicle body cover is surrounded by the separate frames 18, 18 and the lower pipes 34, 34, a container-like outer shape of the pipe frame can be formed as a whole, and the appearance can be improved.
Further, as is apparent from the figure, a large-scale bracket for attaching the cover is not required, and the manufacturing cost of the vehicle body frame can be reduced.
[0038]
Next, a handle lock mechanism provided for theft prevention will be described. However, in the present invention, a so-called combination lock device in which a handle switch mechanism is incorporated in the combination switch is employed.
[0039]
FIG. 9 is an exploded perspective view of the combination lock device according to the present invention. The combination lock device 70 includes a key hole 71, switches (not shown because they are built in), and a pin insertion / extraction mechanism (built-in / out) for making the lock pin 72 protrude and retract. (Not shown), a unit support bracket 74 for attaching the combination / lock unit 73 to the head pipe 12, and a gate type fixed to the unit support bracket 74 with three screws 75. It comprises a bracket 76, a shutter housing 78 fixed to the portal bracket 76 by bolts 77 screwed from below, and a lock plate 81 welded and fixed to a steering shaft 79.
[0040]
The lock plate 81 has two lock holes 82A and 82B. Since the head pipe 12 is a non-rotating member and the steering shaft 79 is a rotating member, the steering wheel 79 can be locked on the head pipe 12 by locking the steering shaft 79 side. The combination lock device 70 of the present invention is based on this principle.
[0041]
In order to achieve the above principle, the combination lock unit 73 is fixed to the unit support bracket 74 provided on the back surface of the head pipe 12 with bolts 83, 83, and the combination lock unit 73 is placed over the combination lock unit 73. Attach the bracket 76. It is desirable that the shutter housing 78 be bolted to the portal bracket 76 in advance.
[0042]
FIG. 10 is a perspective view of a combination lock device according to the present invention. , 77.
[0043]
As shown in FIG. 7, the handle post cover 27 covers the head pipe 12 and the steering shaft 79. As a result, most of the combination lock device 70 in FIG. 10 is covered with the handle post cover, and only the shutter housing 78 is exposed. Since the bolts 77, 77 are not visible and the heads of the bolts 77, 77 are below, the bolts 77, 77 cannot be easily loosened from above. As a result, the shutter housing 78 is less likely to be removed, and there is no fear that the combination lock unit 73 will be damaged.
[0044]
11 (a) to 11 (c) are comparison diagrams of old and new combinations and lock devices, (a) and (b) are operation diagrams according to the present invention, and (c) is an operation diagram according to a conventional product.
(A) shows a state in which the steering shaft 79 is turned almost to the left and the lock pin 72 is inserted into the lock hole 82A.
[0045]
(B) shows a state in which the steering shaft 79 is almost fully turned clockwise and the lock pin 72 is inserted into the lock hole 82B.
The longitudinal axis of the combination lock unit 73 extends in the front-back direction of the drawing, and the longitudinal axis is substantially parallel to the steering shaft 79, and the lock pin 72 is horizontal. As a result, the distance L1 from the center of the steering shaft 79 to the outer surface of the lock plate 81 can be set short.
[0046]
(C), the longitudinal axis 202 of the combination lock unit 201 (conventional and comparative examples are denoted by reference numerals in the 200's; the same applies hereinafter), the lock pin 203 is moved up and down, and the lock plate 204 is rotated by a fan. This shows a conventional product composed of a plate. The distance L2 from the center of the steering shaft 205 to the outer surface of the lock plate 204 becomes longer. In addition, since the lock plate 204 and the combination / lock unit 201 have a large area in plan view, it is difficult to arrange other devices around the steering shaft 205.
In this respect, in the product of the present invention shown in (a) and (b), other devices can be easily arranged around the steering shaft 79.
[0047]
Next, the details of the driver's seat 25 and the passenger seat / seat back 26 of the present invention will be described. FIG. 12 is a perspective view showing the rear carrier according to the present invention, and the driver's seat 25 becomes a seat with a backrest when the passenger seat / seat back 26 is erected. By operating the lock lever 86 attached to the connecting link 85, the angle of the passenger seat / seat back 26 can be changed.
[0048]
It also shows that the rear carrier 87 and the grab rail 32 are attached to the rear frame 35.
The rear carrier 87 is made of a resin or light metal uneven plate. In the case of an uneven plate, the section modulus can be remarkably increased as compared with a flat plate, and more luggage can be loaded.
[0049]
FIG. 13 is a cross-sectional view taken along line 13 of FIG. Indicates that you can do it.
[0050]
Further, a triangular bracket 91 is extended from the round pipe-shaped rear frame 35 toward the center of the vehicle body, two holes 93 and 94 are opened in the upper surface plate 92 of the triangular bracket 91, and a rear carrier 87 is bolted into the inner hole 93. Fix with. This shows that the base 96 of the grab rail 32 is attached to the outer hole 94 with the bolt 97.
[0051]
The upper surface plate 92 of the triangular bracket 91 is set higher than the upper surface of the rear frame 35 by a distance t. The distance t is 1-2 mm. The reason for adopting such a structure is as follows.
[0052]
If a structure in which the round pipe-shaped grab rail 32 is directly attached to the round pipe-shaped rear frame 35 is adopted, the lower end of the grab rail 32 is brought into contact with the rear frame 35 and the abutting portion is welded. Alternatively, in the case of fastening with a bolt-on type as being detachable, the fastening portion appears in the appearance.
[0053]
Therefore, in the present invention, the base 96 is extended from the lower end of the grab rail 32, the tip of the base 96 is inserted under the rear carrier 87, and then bolted to the triangular bracket 91. The appearance is good because it can be attached and detached and the fastening part is not visible.
[0054]
However, a force is naturally applied to the grab rail 32, and the base 96 bends up and down. The base 96 may interfere with the rear frame 35.
Therefore, the base 96 was regarded as a cantilever, the deflection was calculated, and the distance t was set to a value exceeding the assumed deflection to prevent interference.
[0055]
FIG. 14 is a view taken in the direction of arrow 14 in FIG. 12, and shows the rear (bottom) structure of the passenger seat / seat back 26. The passenger seat / seat back 26 further surrounds a seat bottom plate (reference numeral 98 in FIG. 17 to be described later) surrounding the cushion material with a back plate 101, for example, a total of four T-shaped hooks on the upper left and right and the lower left and right. 102... Are provided.
[0056]
When no luggage is placed on the rear part of the vehicle body, the back plate 101 becomes an external appearance member, and is made of a beautiful plate material. Moreover, since the bending force is applied by the T-shaped hook 102, it is necessary to increase the rigidity. Therefore, the back plate 101 is made to be an uneven plate to increase the section modulus. The back plate 101 is suitably made of a steel plate, a resin plate, or the like, and is an external member, so that a surface treatment such as painting, plating, and coloring is performed.
[0057]
FIG. 15 is a rear view of the scooter type vehicle according to the present invention, in which the bag 103 and the skateboards 104, 104 are placed on the rear carrier 87, and the grab rail 32 and the passenger seat / seat back 26 (T-shaped hook, not shown). And that the luggage is fixed by hanging the string 105.
[0058]
If only the horizontal rear carrier 87 is used, the cargo moves back and forth due to sudden braking or the like. In the present invention, the forward movement is prevented by the presence of the passenger seat / seat back 26, and the backward movement can be prevented by hanging the string 105 on a T-shaped hook (not shown).
In this manner, a large amount of luggage can be stably carried on the rear luggage carrier 87 and transported.
[0059]
The storage compartment 106 is provided on the right side of the rear carrier 87, and the storage compartment 106 will be described later in detail.
[0060]
FIG. 16 is an explanatory view of a seat slide mechanism employed in the present invention. The driver's seat 25 of the present invention can change the front-rear position according to the driver's preference. 110 is provided at the rear of the vehicle body.
[0061]
The seat slide mechanism 110 includes left and right seat rails 111L and 111R, left and right sliders 112L and 112R slidably mounted on these seat rails 111L and 111R, and slide lock saw teeth provided on the right slider 112R. A member 113, an operation lever 114 for rotating the sawtooth member 113 to switch between a locked state and an unlocked state, cross members 115 and 116 before and after connecting the left and right sliders 112L and 112R, and a rear part of the right slider 112R. And a link 117 extending from the rear of the left slider 112L.
[0062]
The left and right sliders 112L and 112R can be freely moved back and forth.
Then, the driver's seat 25 is fixed to the left and right sliders 112L and 112R, and the passenger seat / seat back 26 is fixed to the connecting link 85 and the link 117. As a result, the driver releases the slide lock by operating the operation lever 114, moves the driver's seat 25 and the passenger seat / seat back 26 to an arbitrary front and rear position, and returns the operation lever 114 to the position. The driver's seat 25 and the passenger / seat back 26 can be fixed.
[0063]
Further, the driver or the passenger can operate the lock lever 86 to bring the passenger seat / seat back 26 into a horizontal state as shown in the figure.
[0064]
FIG. 17 is a sectional view taken along the line 17-17 in FIG. 16 (the grab rail is omitted). If the sectional structure of the passenger seat / seat back 26 is described first, the passenger seat / seat back 26 is made of a cushion material 118 such as a sponge. , A skin 119, and a seat bottom plate 98, a reinforcing bone 121 is attached to the seat bottom plate 98, legs 122, 122 are extended from the seat bottom plate 98, and tips of the legs 122, 122 are provided. This is a structure in which pads 123, 123 are attached to (lower end in the figure).
[0065]
The reinforcing bone 121 is connected to the link 117 shown in FIG.
Further, in the seat bottom plate 98, the edges 124, 124 are bulged downward so as to give the seat a sense of thickness, and a concave portion 125 is formed in the center. The recess 125 and the reinforcing bone 121 are collectively covered with the back plate 101, and the appearance when the passenger seat / seat back 26 is erected is improved.
[0066]
The legs 122, 122 are projected to positions matching the left and right inner rails 88, 88. Then, the weight of the passenger can be directly supported by the inner rails 88, 88 via the legs 122, 122 and the legs 89, 89 of the rear carrier 87. Only the compressive force acts on the legs 89, 89 of the rear carrier 87, and no bending force acts on the rear carrier 87.
[0067]
The height of the T-shaped hooks 102, 102 is set so that a gap g can be secured from the rear carrier 87. The gap g is 4 to 5 mm.
[0068]
In general, a small vehicle may employ a tiltable hook or a hook that can be moved in and out of a carrier. This is because it can be stored when not in use so that the appearance can be maintained, and when it is pulled out when in use, the hook can be made large and the strap allowance can be earned.
However, if the passenger seat / seat back 26 is overturned while the tiltable hook and the removable hook are left in the out state, the rear carrier 87 may be damaged and the hook may be damaged.
[0069]
In this regard, the present invention employs a fixed hook. With a fixed hook, there is no need to worry about forgetting to close, and there is no risk of damaging related parts. However, since the mounting space is limited, the size of the fixing hook cannot be increased. Therefore, the T-shaped hook 102 is employed. In the case of a T-shape, two right and left claws can be secured on the horizontal bar of T with the vertical bar of T as the center, and the string can be sufficiently hung on the vertical bar and the two right and left claws. That is, although the T-shaped hook is smaller than the L-shaped hook, the hanging cost of the string can be increased.
[0070]
Next, the details of the storage box 106 provided below the right side of the rear loading platform will be described.
FIG. 18 is a perspective view of the container according to the present invention. The container 106 includes a container 126 having a lateral opening 125, a flange 127 projecting forward from the edge of the opening 125 of the container 126, and the opening 127. The lid 128 includes a lid 128 that closes the lid 125, and hinges 129 and 129 that connect the lid 128 to a lower edge of the opening 125.
The container 106 is attached to the vehicle body by attaching the container 126 to the rear frame 35.
[0071]
FIG. 19 is a view taken in the direction of arrow 19 in FIG. 18 and shows that the secondary air control valve 131 is disposed behind the collar 127 of the container 106. The secondary air control valve 131 supplies an appropriate amount of air to the exhaust system of the engine, thereby promoting the combustion of the exhaust gas, burning the unburned gas remaining in the exhaust gas, and purifying the exhaust gas. Important equipment for.
[0072]
Such an important secondary air control valve 131 is generally housed in a body cover in a scooter type vehicle.
In the present embodiment, the secondary air control valve 131 is not stored in a body cover such as a side cover.
In this case, it is necessary to cover the secondary air control valve 131 with a dedicated protective cover in order to deal with flying stones from the outside. In this case, a dedicated protective cover, a mounting bracket and screws are required, and the number of parts is increased.
[0073]
In the present invention, the flange 127 is extended from the container 106 disposed in the vicinity, and the flange 127 protects the secondary air control valve 131. As a result, there is no need to newly provide a dedicated protective cover, mounting bracket, and screws, and the number of parts can be reduced.
