Description

  The present invention relates to a vehicle cover having a fine pattern on its surface.

  Most of the covers for the vehicle have a smooth surface, but some have a ridge-like uneven pattern called wrinkles. Various forms of the uneven pattern have been proposed (see, for example, Patent Document 1 (FIG. 2)).

As shown in FIG. 2 of Patent Document 1, the wrinkles are streamlined, and depending on the shape and size of the wrinkled portion, darkness occurs randomly (irregularly), and the appearance Decreases. The height of the embossment is 5 to 150 μm (paragraph number 0014). However, if the height of the embossment exceeds 100 μm, the product will not easily come off the mold. Demoldability is poor and affects productivity.
Therefore, a vehicle cover that has good appearance and good releasability is desired.

JP-A-9-29906

  An object of the present invention is to provide a vehicle cover that has good appearance and good releasability.

The invention according to claim 1 is a vehicle cover having a fine pattern on the surface,
The pattern is a polygonal arrangement of polygons,
The polygonal body includes a satin portion in which a satin pattern is provided on a first reference surface provided at a position protruding a predetermined distance from the base surface, and a second provided at a position near the base surface from the first reference surface. And a stripe portion having a straight line pattern made of a plurality of valley grooves on the reference surface.

  In the invention according to claim 2, the height of the first reference surface from the base surface is set to a range of 95 to 105 μm, the depth of the satin pattern is set to a range of 25 to 35 μm, and the depth of the valley groove The length is set in a range of 35 to 40 μm.

  In the invention which concerns on Claim 3, the pitch of the hollows which form a satin pattern is set to an unequal space | interval, the pitch of a trough is set to a fixed value, and a fixed value is 0.20 mm-0.50 mm. It is set to a range.

  In the invention which concerns on Claim 4, the area ratio of a satin part and a stripe part is set to the range of 1: (2-10), and a satin part is extension of some troughs in a plurality of troughs. It is characterized by being arranged on a line.

  In the invention according to claim 5, the polygonal body is a hexagon, the satin portion is an isosceles triangle having one side of the hexagon as a base, and the area ratio between the satin portion and the stripe portion is set to 1: 5. It is characterized by.

  The invention according to claim 6 is characterized in that the polygonal body has a size that fits in a rectangle of 6 mm in length and 10 mm in width.

  In the invention according to claim 7, the vehicle cover according to any one of claims 1 to 6 is a side cover disposed below a seat on which a fuel tank or an occupant sits in a side view of the vehicle. Further, the troughs are arranged obliquely so as to be lowered toward the front of the vehicle.

  In the invention according to claim 1, the pattern is formed by densely arranging polygonal bodies. Since the polygons are arranged closely, a regular geometric pattern is obtained and the appearance is improved. In the stripe portion, there is no anti-slip action in the direction along the trough, but the anti-slip action in the direction orthogonal to the trough is high. Further, since there is a step between the first reference surface and the second reference surface, the anti-slip action is exhibited at this step. Furthermore, since the first reference surface is subjected to a satin finish, it exhibits an antiskid action regardless of the direction.

  In the invention which concerns on Claim 2, since the depth of a satin pattern and the depth of a trough are both less than 100 micrometers, releasability is favorable. Furthermore, by making the valley groove deeper than the satin pattern, the valley groove pattern can be clarified, and the design can be further improved.

  In the invention according to claim 3, since the pitch of the recesses forming the satin pattern is set at unequal intervals and the pitch of the troughs is set to a constant value, it is possible to differentiate between the satin pattern and the striped pattern, and Can be regular and clear. The pitch of the troughs is selected from the range of 0.20 mm to 0.50 mm, but it looks dark around 0.20 mm and appears light around 0.50 mm. Therefore, the pitch of the troughs is preferably in the range of 0.20 mm to 0.50 mm from the viewpoint of contrast.

In the invention which concerns on Claim 4, the area ratio of a satin part and a stripe part is set to the range of 1: (2-10), and a satin part is extension of some troughs in a plurality of troughs. It is arranged on the line.
By increasing the area ratio of the stripe portion, the regular pattern area is increased and the appearance is improved.

Further, if the area ratio deviates from 1: (2 to 10) and the areas of the satin portion and the stripe portion are approximated, the stripe portion becomes too small to obtain a desired slip. On the other hand, when the area ratio deviates from 1: (2 to 10) and the pear-finished portion becomes small, the anti-slip action is reduced.
In this respect, by setting the area ratio of the satin portion to the stripe portion in a range of 1: (2 to 10), both the slip action by the stripe portion and the anti-slip action by the pear portion can be exhibited. .

  In addition, when the polygonal body and the neighboring polygonal body are viewed as a set, a satin pattern is inserted between the troughs. Even if an object slides along a trough, the object is stopped with a satin pattern and slides again along the next trough. That is, shapes such as sliding, stopping, sliding, stopping, etc. can be created.

In the invention according to claim 5, the polygonal body is a hexagon, and the satin portion has an isosceles triangle having one side of the hexagon as a base, so that the design property is enhanced by a regular geometric pattern.
Moreover, by setting the area ratio of the satin portion and the stripe portion to 1: 5, it is possible to easily create shapes such as slip, stop, slip, stop, and so on.

In the invention according to claim 6, the polygonal body is sized to fit in a rectangle having a length of 6 mm and a width of 10 mm. Since it is horizontally long, it approximates a streamline and provides a pattern suitable for a traveling vehicle.
In addition, since one pear surface is provided for each polygonal body, when a pattern is applied to the knee grip part, if the polygonal body is too large, the number of pear parts that contact the knee will be reduced, preventing slipping. The effect is reduced. On the other hand, if the polygonal body is too small, the satin portion becomes small and the anti-slip effect is lowered. In order to exert an anti-slip effect on the knee, the size of the polygonal body is preferably a size that fits in a rectangle having a length of 6 mm and a width of 10 mm.

In the invention according to claim 7, the vehicle cover is a side cover that is disposed below the seat on which the fuel tank or the occupant sits in a side view of the vehicle, and the side cover is inclined so that the trough is lowered forward of the vehicle. Is arranged.
If the vehicle is a motorcycle, the pattern of the present invention can be applied to a portion where the occupant knee-grips (between both knees). Movement in the height direction (vertical direction) of the knee before the knee grip can be performed along the stripe portion, and the knee can be fixed at the pear-finished portion during knee grip, and the stripe portion can move the knee in the longitudinal direction. Fixing can also be performed.

It is a right view of the vehicle provided with the cover which concerns on this invention. It is a single item figure of the cover for vehicles concerning the present invention. It is an enlarged view of a pattern. FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. It is a dimension figure of a polygon. It is an action figure of a polygon.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.

  As shown in FIG. 1, the vehicle 10 includes a front wheel 11 and a rear wheel 12, a handle 13 above the front wheel 11, and a seat 16 on which a fuel tank 14 and an occupant 15 indicated by an imaginary line sit behind the handle 13. In this order, and a motorcycle 17 having an engine 17 under the fuel tank 14.

  The vehicle 10 is further disposed along the lower side of the fuel tank 14 so as to close the space between the front cover 21 disposed around the handle 13 and the fuel tank 14 and the main frame 18 in order to prevent traveling wind toward the occupant 15. A vehicle cover 20 including a side cover 22 and a rear cover 23 extending in a direction from below the seat 16 is provided.

  The occupant 15 sandwiches the fuel tank 14 and the side cover 22 with the knees 15a during traveling. This pinching operation is called a knee grip. In order to improve the knee grip performance, it is desired that the side cover 22 is subjected to a non-slip treatment.

As shown in FIG. 2, the side cover 22 is a resin member that extends in the vehicle front-rear direction, and includes an external surface 25 and a non-external surface 26 that surrounds the external surface 25. The pattern 30 is given. Polypropylene is recommended as the resin, and the polypropylene member is molded with a JIS-S55C mold.
The form of this pattern 30 will be described in detail below.

As shown in FIG. 3, the pattern 30 is formed by densely arranging polygonal bodies 31 in a honeycomb shape. The polygon 31 is a horizontally long hexagon in this example, but may be a quadrangle or an octagon. Hereinafter, a hexagonal example will be described in detail.
That is, the polygon 31 includes first to sixth sides 32 to 37, the first side 32 and the fourth side 35 are parallel, the second side 33 and the fifth side 36 are parallel, and the third side 34 and the sixth side 37 are parallel.

  The polygonal body 31 includes a stripe portion 39 on which a straight line pattern made up of a plurality of parallel valley grooves 38 is applied, and a pear texture portion 42 on which a pear texture pattern 41 is applied. The pear texture means the surface of a pear (a kind of fruit), and the pattern on the pear surface is called a pear texture.

  In this example, the satin portion 42 is an isosceles triangle having the first side 32 as the base and the vertex 43 matching the hexagonal center (center of gravity, centroid). Of the two oblique sides of the isosceles triangle, the trough 38 is parallel to the upper oblique side 44.

  In terms of area, the polygonal body 31 can be divided (segmented) into six isosceles triangles. Then, the area ratio of the satin portion 42 and the stripe portion 39 is 1: 5. This 1: 5 is only a suitable example, and the area ratio between the satin portion 42 and the stripe portion 39 may be set in a range of 1: (2 to 10).

The adjacent polygon body 31 and the polygon body 31 are separated from the adjacent polygon body 31 by the base groove 45.
As shown in FIG. 4, a surface passing through the bottom of the foundation groove 45 is defined as a foundation surface 47. A surface set at a position protruding from the base surface 47 by a distance Z is a first reference surface 48, and a satin pattern 41 is provided on the first reference surface 48. The pitch between the recesses 49 of the satin pattern 41 is unequal.

A second reference surface 51 is set at a position away from the first reference surface 48 by the distance X2 from the base surface 47, and a trough 38 is formed in the second reference surface 51.
The distance Z is preferably set in the range of 95 to 105 μm.
The depth of the satin pattern, that is, the depth X of the recess 49 is set in the range of 25 to 35 μm.

The distance X2 is set in the range of 25 to 35 μm.
The depth Y of the valley groove 38 is set in the range of 35 to 40 μm.
The pitch Pg of the valley grooves 38, 38 is a constant value selected from the range of 0.20 to 0.50 mm.

  In the case of resin molding using a mold, if the depth of the groove is 100 μm or less, the release property is good. In this example, the depth X is 35 μm or less, the depth Y is 40 μm or less, and the depth of the foundation groove 45 is 75 μm or less by the formula of Z-X2, so that the releasability is good. .

As shown in FIG. 5, the polygonal body 31 is sized to fit in a horizontally long rectangle 52 of length a × width b. The length a is preferably 6 mm, and the width b is preferably 10 mm.
The length of the first side 32 which is the base of the isosceles triangle is 0.5 × a, and the height of the isosceles triangle is 0.5 × b. Therefore, the shape of the polygon 31 is easily determined.

The operation of the vehicle body cover described above will be described next.
In FIG. 1, an occupant 15 indicated by an imaginary line straddles the seat 16 in the stopped vehicle 10. Next, the handle 13 is grasped, and the hip point (the contact point between the seat 16 and the hip) is moved forward and backward to determine the hip point. During traveling, knee grip is performed where the side cover 22 is sandwiched between the knees 15a.

Although the hip point moves back and forth on the seat 16, the knee 15a rotates around the step 19. This rotation can be approximated by a linear motion that falls forward.
In FIG. 6, the right side of the drawing is the front, the left side of the drawing is the back, and the line G corresponds to the flow line of the linear motion that falls forward. Since the flow line G coincides with the valley groove 38, the knee 15a slides along the valley groove 38, and the knee 15a can move smoothly in the front-rear direction. Movement of the knee 15 a in the height direction (vertical direction) is prevented by the stripe portion 39.

  In addition, along the flow line G, the stripe part 39 and the satin part 42 appear alternately. At the satin portion 42, the knee 15a is stopped. That is, slip, stop, slip, stop ... appear. However, since the hip point is moved while the knee 15a is relaxed, the knee 15a is not stopped by the satin portion 42, and the knee 15a can be moved.

Next, consider the knee grip.
The area of the isosceles triangle is (3 mm × 20 mm) / 2 = 30 mm ² . The area of the polygonal body 31 is 180 mm ² which is 6 times. On the other hand, the contact surface of the knee is about 50 mm × 80 mm, and its area is about 4000 mm ² . According to the calculation of 4000/180 = 22.2, about 22 satin portions 42 contact the knee 15a. These satin portions 42 exhibit an anti-slip action.

  Therefore, by applying the polygonal body 31 of the present invention to the side cover 22 of the motorcycle, the design is improved due to the geometric pattern, and the rideability due to the ease of movement of the hip point and the ease of the knee grip. Can be improved.

The pattern of the present invention may be applied to the rear cover, the front cover, and other vehicle body covers in addition to the side cover.
The numerical values related to the dimensions, distance, and depth are suitable examples, and may be appropriately changed according to the shape, part, and application of the vehicle body cover.
Furthermore, although the vehicle is a motorcycle in the embodiment, it can also be applied to a tricycle or a four-wheel vehicle.

  The present invention is suitable for a side cover of a motorcycle.
