DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle skull seat cover device which can be attached to and detached from the seat of a motorcycle skull which is operated by a driver across a vehicle body.

[0002]

2. Description of the Related Art FIG. 10 shows a general structure of a motorcycle skull 1. A front wheel 3 and a rear wheel 4 to which a steering wheel 6 is connected are suspended from a vehicle body 2 on which an engine and the like are mounted, and the vehicle is driven by a steering operation of a driver sitting on a seat 5 across the vehicle body 2.

Here, the seat 5 is made of an elastic member (for example, a sponge) 5T covered with the seat 5S in terms of riding comfort.
And the upper surface 5A is horizontal, tapered and wide. In particular, the seat 5 (5S) of the motorcycle skull frequently used for business use is wide.

[0004]

However, the sheet 5S
Is made of synthetic artificial leather (for example, vinyl leather or the like) which is rich in waterproofness, and therefore, when parked under the scorching sun, the temperature rises remarkably. For example, high heat of 70 ° C. or more is obtained. Therefore, it is painful to straddle this. Moreover, the human body (buttock) of the driver is almost in direct contact with the thigh seat 5 (seat 5S) via the pants. Further, the heat source of the seat 5 tends to radiate heat through a human body having a high thermal conductivity above and close to the lower sponge (5T).
Thus, for example, a mailman must withstand long periods of high temperature pain while traveling.

SUMMARY OF THE INVENTION An object of the present invention is to provide a seat cover device for a motorcycle skull capable of producing a cooling effect without causing a driver to come into direct contact with a hot seat and generating an air flow between the seat and the driver when the vehicle starts running. Is to provide.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a motorcycle skull seat cover device which can be attached to and detached from the seat of a motorcycle skull which is operated by a driver across a vehicle body.
A planar outer shape is formed in a shape corresponding to the planar outer shape of the seat, and a frame member made of an endless wire rod, while engaging necessary portions with the frame member in a space surrounded by the frame member. A cushion made of a coiled member stretched, a seat cover formed by joining a front surface cloth and a back surface cloth so that the frame member and the cushion can be accommodated, and attaching / detaching means formed so that the seat cover can be attached to and detached from the seat; It is selected so that at least a large part of the surface cloth is formed of a coarse cloth having a high air permeability, and an air flow layer can be secured between the buttocks of the driver seated with the cushion and the upper surface of the seat. A motorcycle scull seat cover device which has vertical rigidity and is formed so that outside air flowing in from the front side of the surface cloth during traveling can flow out of the rear side while flowing through the air fluidized bed. A.

In this invention, the attaching / detaching means (for example, a string)
Attach the seat cover to the seat using. The back cloth is in direct contact with the seat, but the front cloth is non-contact because it is through the cushion. That is, even if the upper surface of the seat is hot, the coarse surface cloth is unlikely to become hot.

Here, even if the driver sits on the surface cloth while straddling the vehicle body, an air fluidized layer is secured between the driver and the upper surface of the seat due to the rigidity of the cushion. No contact. Moreover, since the cushion is formed by stretching the coil-shaped member, the volume is small and the heat storage capacity is small, so that the heat sensitivity to the human body can be almost ignored. Therefore, the driver does not suffer from the high temperature while sitting.

Further, the planar shape of the seat cover is equivalent to the planar shape of the seat, and the cushion has flexibility of the coil-shaped member, so that the cushion can follow the vertical elastic deformation of the seat itself as a whole. Moreover, since the frame member is made of a wire,
The entire seat cover adapts to the three-dimensional shape of the seat. In other words, it fits in the straddling posture. Therefore, sitting comfort is also good.

[0010] Further, when the vehicle starts traveling, outside air from the front side flows in through each coarseness of the surface cloth, flows through the air fluidized bed in the cushion, and rapidly cools (heat-cools) the high temperature of the seat and the human body. It flows out rearward through each grain of the surface cloth. Therefore, since the seating temperature can be further reduced and there is no stuffiness, further comfortable running can be assured.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. Book seat cover device 10
As shown in FIGS. 1 to 7, the frame member 20 and the cushion 3
0, the seat cover 40, and the attachment / detachment means 50, and at least most of the surface cloth 41 is made of a coarse (4
1) It is formed of a cloth and has a vertical rigidity selected so as to secure an air fluidized layer 31S between the human body (buttock) of the driver on which the cushion 30 is seated and the upper surface 5A of the seat. The outside air flowing in from the front F side of the surface cloth 41 is formed so as to flow out of the rear R side while flowing through the air fluidized bed 31S.

The motorcycle skull 1 is the same as that of the conventional example (FIG. 10), and is used by being attached to the seat 5. However, the motorcycle skull itself is not limited to the case of FIG. For example, the present invention can be applied to an electric bicycle and an electric tricycle.

In FIG. 3, the frame member 20 is formed of an endless wire rod 21 having a planar outer shape corresponding to the planar outer shape of the seat 5 (a tapered rear wide saddle type). More specifically, the wire 21 is bent using a bending machine having, for example, three rollers, and one end 22 and the other end 23 are connected to a joint 24.
And connected endlessly. The frame member 20 is entirely deformable due to its flexibility when an external force is applied. This is to make it easier to adjust to the three-dimensional form of the seat 5. In consideration of this point, the joint 24 is provided at a position (linear portion) where only the axial force is applied. The ends 22 and 23 may be connected by welding or the like. Of course,
The connection position is not limited to the above-described linear portion.

In this embodiment, the frame member 20 is made of a carbon-containing iron wire having a diameter [d shown in FIG. 4A] of 2.9 mm. The material may be spring steel or the like. Also,
A pipe may be used instead of muku. Joint 24
Is made of iron, but may be steel, synthetic resin, or the like.

The cushion 30 is provided in a space S surrounded by the frame member 20 shown in FIGS. 3 and 4A. ) Is made up of a coil-shaped member 31 which is stretched (transposed) while engaging.

More specifically, the coil-shaped member 31 is formed as shown in FIG.
A carbon-containing iron wire 34 having a diameter of 0.9 mm shown in FIG.
S was coated with a coating material (vinyl) 34C, and was made from a wire 34W having an outer diameter d1 of 1.35 mm. A winding machine was used. That is, as shown in FIG.
The coil-shaped member 31 having a length of 0 mm and a total length of 4 m was formed.

The covering material 34C is made of a carbon-containing iron wire 34S.
In order to prevent the temperature from rising and prevent the temperature from being transmitted to the seated driver. Another purpose is to eliminate the possibility that rust adheres to the pants.

Then, one end of the coil-shaped member 31 is
The frame member 20 not yet connected by the joint 24 is fitted from one end 22 to the other end 23 and fitted over the entire length of the frame member 20. Subsequently, it is engaged with another portion of the frame member 20 across the space S, and thereafter, it is engaged with another portion of the frame member 20 or the middle of the coil-shaped member 31,
Finally, the other end is locked in another part of the frame member 20 or in the middle of the coil-shaped member 31. In addition, the portions where the coil members cross each other are engaged (engaged).

Thus, as shown in FIGS. 1 and 4A,
A single coil-shaped member 31 having a total length of 4 m is stretched (transferred) to the frame member 20, and a spider web-shaped cushion 3 is provided in the space S.
0 can be formed and held. Therefore, since the cushion 30 has a small volume and a small heat storage capacity, the heat sensitivity to the human body can be almost ignored.

However, there are cases in which the stability of seating is low and the establishment of the air fluidized bed 31S is not complete. Accordingly, in this embodiment, the entire cushion 30 held by the frame member 20 is pressed to a height H1 (vertical dimension in the figure) of, for example, 11 mm as shown in FIG. Is flattened. After the press is released, the height H2 shown in FIG.
(For example, 17 mm).

That is, the up-down rigidity of the cushion 30 is selected so that the air-fluidized bed 31S having a height H1 to H2 can be secured between the seated driver's body (buttock) and the upper surface 5A of the seat. Of course, the flexibility of the cushion 30 is not lost.

The seat cover 40 is a bag formed by joining a front cloth 41 shown in FIG. 5 (A1) and a rear cloth 44 shown in FIG. 5 (C1) so that the frame member 20 and the cushion 30 can be accommodated. The material of each cloth may be natural fiber or chemical fiber. In addition, the processing method can be appropriately selected from, for example, a woven fabric and a knitted fabric shown in FIG. 6A and an injection molded product shown in FIG. 6B.

Regardless of the material and processing method, at least a large part of the surface cloth 41 has a rough surface 42 having a high air permeability.
Should be a cross. In this embodiment, for both cloths 41 and 44, a knitted fabric of coarse 42 and 45 excellent in air permeability of a synthetic resin (polypropylene) shown in FIG. The back cloth 44 is also made of coarse 45 with excellent ventilation.
Since the knitted fabric is used, the cooling effect of the seat 5 during traveling can be further promoted.

However, since the back cloth 44 does not directly contact the driver, it may be fine or blind. For example,
The use of a rubber seat can further enhance the adhesion of the seat 5 (seat 5S).

In FIGS. 1, 5 and 7, the coarse 42,
45 is exaggerated (enlarged) for convenience of explanation and simplification of illustration.

The front cloth 41 and the back cloth 44 are the upper part of the front cloth 41 shown in the upper half of FIG. 5B and the lower part of the back cloth 44 hatched for the lower half. The part to be formed is sewn using an edge material (for example, a vinyl sheet) 47. However, the rear wide portion is sewn after the frame member 20 incorporating the cushion 30 is inserted.

Note that a part of the surface cloth 41 is shown in FIG.
For example, a reinforcing sheet 43 made of synthetic artificial leather or the like for improving durability as shown in FIG. Generally, it is preferable to provide them at the front and / or the rear.

As shown in FIG. 5 (C 2), a synthetic leather 48 having a string hole 49 can be attached to the back cloth 44. This is for the convenience of the configuration of the attaching / detaching means 50 described later.

The attachment / detachment means 50 includes a seat cover 40 (41, 41).
44) is attached to and detached from the seat 5. In this embodiment, the rubber band 51 on the front side and the rubber band 5 on the rear side shown in FIG.
2 are formed. Therefore, the elastic band 5
Easily attach to the seat 5 using the elasticity of 1,52
Can be removed.

It should be noted that, for example, depending on the form of the seat 5, for example,
As shown in FIG. 7B, the front side may be a string 51L, and as shown in FIG. 7C, the rear side may be a string 52L. Of course, the structure of the attachment / detachment means 50 is not limited to the above example. The string hole 49 of the synthetic artificial leather 48 shown in FIG. 5 (C2) may be used, or a rocking band structure or the like may be adopted. However, according to this embodiment [FIG. 7 (A)], attachment / detachment is easy and it can be realized at low cost.

According to the seat cover device 10 of this embodiment, the seat cover device 10 is attached to the seat 5 using the attaching / detaching means 50 as shown in FIG. Although FIG. 2A is simply displayed for convenience of description, in this embodiment, the frame member 20 is located below the upper surface 5A of the seat 5 as shown in FIG. 2B. . That is, since the entirety of the seat cover device 10 can be adapted to the form of the seat 5 by the flexibility of the cushion 30 (coil-shaped member 31), it is difficult to separate from the seat 5, and the cushion 30 and the seat 5 (elasticity, member 5T) Can be integrally displaced in the vertical direction. That is, it is possible to easily follow the elastic deformation of the seat 5 during traveling.

In this sense, in FIG. 5, the front cloth 41 and the back cloth 44 have the same planar outer shape. However, in order to make the seat cover 40 slightly concave, the front cloth 41 must be formed on the back cloth. It is preferable to cut the cloth larger than the cloth 44. In the practice of this standard shape, the surface cloth 41 side is enlarged by about 1 cm over the entire circumference.

In any case, the back cloth 44 is attached to the seat 5
(Sheet 5S) is directly in contact, but is not in contact with surface cloth 41 via cushion 30. In other words, even when the upper surface 5A of the seat 5 is hot due to being parked in the hot sun, the surface cloth 41 of the rough surface 42 is unlikely to be hot.

Here, even when the driver sits on the surface cloth 41 while straddling the vehicle body 2, the rigidity of the cushion 30 secures the air flow layer 31S between the driver and the upper surface 5A of the seat. There is no direct contact with the hot seat 5 (5S, 5A). Moreover, since the cushion 30 is formed by stretching the coil-shaped member 31, the volume is small and the heat storage capacity is small, so that the heat sensitivity to the human body can be almost ignored. Therefore, the driver does not suffer from the high temperature while sitting.

The planar shape of the seat cover 40 is the same as the planar shape of the seat 5, and the cushion 30 has the flexibility of the coil-shaped member 31, so that the cushion 30 can follow the vertical elastic deformation of the seat 5 itself. In addition, the frame member 20 is
Therefore, the entire seat cover conforms to the three-dimensional shape of the seat 5, that is, fits in a straddling posture. Therefore, sitting comfort is also good.

Further, when the vehicle starts traveling, as shown in FIG. 1 and FIG. 2, outside air from the front F side flows in from each coarse surface 42 of the surface cloth 41 and the air fluidized layer 3 in the cushion 30.
While flowing 1S and rapidly cooling (air cooling) the high temperature of the seat 5 and the human body, it flows out to the rear R side through each coarse portion 42 of the surface cloth 41. Therefore, since the seating temperature can be further reduced and there is no stuffiness, further comfortable running can be assured.

In addition, the back cloth 44 (coarse 45)
Since it is the same as the surface cloth 41 (coarse 42), the seat 5
(Sheet 5S) can be rapidly cooled. Therefore, the high temperature state is not carried over until the next parking. Further, at the time of parking, the seat cover device 10 can be detached from the seat 5 by releasing the attaching / detaching means 50, so that the high temperature pain at the time of re-boarding can be more completely avoided.

According to this embodiment, the frame member 20, the cushion 30, the seat cover 40, and the attaching / detaching means 50 are provided.
The body cloth (buttocks) of the driver on which most of the surface cloth 41 is formed of a coarse (42) cloth with high air permeability and the cushion 30 is seated, and the seat upper surface 5
A has a rigidity in the vertical direction selected so that the air fluidized bed 31S can be secured between itself and the surface cloth 41 (42) during traveling.
The outside air flowing in from the front F side is formed so as to be able to flow out of the rear R side while flowing through the air fluidized bed 31S, so that the driver does not directly contact the high-temperature seat 5 and becomes The cooling effect can be caused while causing the air flow with the driver. Therefore, comfortable driving can be performed without suffering from high-temperature pain.

The frame member 20 is made of an elastically deformable wire 2
1 and the seat cover device 10
The whole can be adapted to the form of the seat 5 and the seat 5
(Elastic member 5T) can easily follow elastic deformation during traveling. Therefore, since a sense of unity with the seat 5 can be maintained, a stable running without a sense of incongruity can be guaranteed.

The cushion 30 is made of a coil-like member 31.
Is pressed and flattened in a state of being assembled in the frame member 20, so that a stable air fluidized bed 31S can be established, and there is no local protrusion, and sitting comfort is good.

The height of the cushion 30 is 17
mm (H2) and 11 mm (H1) when seated,
The radiation heat of the seat 5 can be prevented from being transmitted to the human body.

Further, since the cushion 30 is covered with the covering material 34C, the temperature of the coil-shaped member 31 can be suppressed from increasing, and the temperature does not propagate to the human body. Even if rust is generated on the coil-shaped member 31, it does not adhere to the pants.

Further, since the surface cloth 41 is made of a knitted fabric having a coarse texture 42, it is comfortable to sit while obtaining sufficient air permeability. For example, knitting of hemp or paper can further improve sitting comfort.

The back cloth 44 is also the front cloth 41.
(Coarse 42), the seat cover 40 is made of a knitted material having the same coarse 45 as that of the seat 5 (seat 5).
It becomes easy to adjust to S), and the high temperature of the sheet 5S can be efficiently cooled.

Further, the attaching / detaching means 50 is provided with the rubber band 5
Since it is formed from 1,52, it can be easily attached to and detached from the seat 5, and the cost is low. Therefore, it is easy to remove it during parking. On the other hand, since the seating portion (surface cloth 41) of the seat cover 40 is made of a coarse-knit polypropylene knit, even if it is wet with rain while wearing it, the seat can be immediately seated without any problem.

In the above embodiment, the cushion 3
The method (structure) of holding (embedding) the 0 in the frame member 20 is as follows.
The frame member 20 and the coil-shaped member 31 forming the cushion 30 are used to form a so-called spider web, but the present invention is not limited to this. For example, as shown in FIG. 8A, the coil-shaped member 31 fitted in the frame member 20 is provided with a plurality of auxiliary frame members 28 provided inside the coil-shaped member 31. (See FIG. 9 (B)) and fitting each other sequentially, or as shown in FIG. 9, each end of a plurality of short coil members 31 is locked on both sides of the frame member 20 and It is a structure etc. that makes the middle of each other dangle. In this way, a dense cushion 30 can be created.
