Description of the invention: [Technical field to which the invention belongs] The present invention relates to a wheel of a bicycle. Especially for off-road ground such as ground, mud, sand, etc., and ", and bicycle tires walking on the wheel surface. The / N block is arranged in the tires [prior art] in the harsh road conditions such as mountain bikes and other places, and it can still be tight; ^ In order to walk in the wasteland or mud excellent, ㈣ safe and = plural small bumps 2. Because the walkability or controllability, the muddy property of the: match: r, etc., may be changed or changed due to the shape or configuration of the small bump 2 described above, the shape or configuration of the small bump 2 is adapted to the use of the bicycle or the round shapeΗ ^ η surface, and bicycle tires with different design patterns mentioned above. In this type of bicycle wheel, when the small projection 2 is formed from the center of the wheel surface 2 and the bicycle is driven, as shown by the dotted line in FIG. 8, The above: The large block 2 will deform in the direction opposite to the direction of travel and generate a turn = force ', so there will be a problem that the driving force cannot be efficiently transmitted to the road surface, and the-== performance is deteriorated. Therefore, the above small bumps are: the contact between the road surface and the top surface 21 of the small bumps 2 is transmitted, and the force is transmitted, while the deformation of the small bumps 2 is greatly suppressed, = 行走 the walkability of the bicycle , Maneuverability. ^ Also, the small projections 2 protruding from the above-mentioned wheel surface 10 are prone to wear or damage due to friction or load of the brakes, and the problem of reduced braking danger or turning performance decreases. Therefore, as shown in FIG. 8, the peripheral wall surface 20 of the small projection 2 is formed into an inclined surface shape that increases toward the wheel surface ιo by 200524760, thereby reducing wear or damage and improving durability. In the case of walking on mud, when the mud fills the grooves G between the small bumps 2 above, the weight of the bicycle tire increases with the degree of mud filling, and the small bumps 2 cannot hold the road tightly. , Which reduces walking and handling. In addition, there are safety issues such as slipping. Therefore, the small protrusions 2 are formed into a tapered shape, and a curved portion R is formed at the connection portion between the small protrusions 2 and the wheel surface 10 as shown in FIG. 8, so that the adhesion of mud to the small protrusions 2 can be suppressed. The gap g between the gaps and the mud filled between them can be effectively discharged, thereby improving the mud-discharging performance. [Patent Document 1] Japanese Patent Application Publication No. 5-16 2 2 [Patent Document 2] Japanese Patent Equity No. 7-28004 [Summary of the Invention] (Problems to be Solved by the Invention) However, the structure of the small bumps 2 for improving the performance described above causes side effects. Specifically, when the small bumps 2 are enlarged in order to improve the walkability or controllability, the grooves g of the small bumps 2 are narrowed, and the secretion is worsened, and the weight of the bicycle tire 1 is also increased. increase. In addition, in order to improve durability, the angle of the small projection 2 rising from the wheel surface M is changed by $ 4 / two ', and the amount of inclination of the peripheral wall surface 20 is increased, and the top surface 21 of the small projection 2 in contact with the road surface is increased. The area will become smaller, and the transmission efficiency of the driving force will be worse, rt, Γ will be worse in running or handling, and at the same time, the reduction in friction will also be reduced! Car performance or cornering performance will decrease. When the small dog block 2 described in the above-mentioned 200524760 is formed in a tapered shape to improve the sludge discharge property, the area where the small bump 2 is in contact with the road surface is reduced, which may cause poor walking or handling, and the strength of the small bump 2 is reduced. It is easy to wear or break, so the durability is also reduced. Therefore, 'the combination of structures that can improve each of the above functions makes it possible to walk! · Biocontrol! · Shengdong ij bicycle design, which is excellent in all performances such as performance, cornering performance, durability, and sludge removal, is impossible. of. So actually carry a bicycle tire! When designing, consideration should be given to each foot = vehicle use, or walking conditions such as road surface. In particular, priority should be given to performance enhancement 'to determine the shape or arrangement pattern of the small bumps 2 described above. The present invention has been developed by developers who have fewer problems than the above, and its purpose is to provide a "bicycle tire with a plurality of small bumps arranged on the wheel surface" in terms of walking, handling, braking performance, turning performance, and durability. And sludge, etc. = he is very good in nature ', and the above-mentioned performance of the pedal C does not offset each other's method) This issue "please specifically focus on the bicycle tires in the i-th paragraph," above: fish : The block is composed of a base portion protruding from the wheel surface and having a trapezoidal cross-section; it is composed of the base portion 71 and a columnar block portion, and the block portion and the base portion are connected to each other by a peripheral wall surface. In this way, the rising angle of the peripheral wall surface of the block part is smaller than 90 degrees with respect to the two: wheel surface. The 2 series forms a two-segment structure with the base part 4 and the block part 3, and the base part 4 rises from the wheel surface i. The angle of standing up is small, and the angle θ2 of the block part 3 rising from the wheel surface 10 is large. Therefore, the bicycle drive 200524760 When moving, the contact with the road surface and the bearing height 3 can be reduced, and the force of the opposite direction can be obtained. The block part Ai is supported by the base part 4. Therefore, the deformation of the block part 3 may be made in time. When braking or turning, the base part 4 may be wrong to suppress the small protrusion 2 toward Deformation in the direction of travel. Therefore, the rotation resistance caused by the deformation of the small projections 2 is reduced, and at the same time, the abrasion or damage of the small projections 2 is prevented. The angle formed, and the angle formed by the peripheral wall surface 40 of the base portion 4 and the peripheral wall surface% of the block portion 3 are all field angles. The width of the groove portion G formed between the small protrusions 2 is from the wheel. The surface 10 increases toward the front end of the small slit 2. Therefore, it is difficult for the mud to fill the groove G, and at the same time, the stuffed mud can be smoothly discharged by the deformation of the small protrusion 2 during driving. In the bicycle tire according to item 2 of the patent, "the center of the top surface of the base portion connected to the block portion is located behind the center of the bottom surface with respect to the traveling direction of the bicycle tire." According to this structure, it is located at the base portion. 4 direction forward The peripheral wall surface 40a has a large amount of inclination, and the angle formed by the above-mentioned wheel surface 10 and the peripheral wall surface 40a of the base portion 亦 is also large, so the mud is not easily attached to the above-mentioned wheel surface 10 and the base portion 4. The connecting portion C can be easily removed even when attached. In the bicycle tire of item 3 of the present invention, "the height of the above-mentioned block portion occupies one-third to one-third of the overall height of the small projection block = 0 』According to this structure, the small bumps 2 can be used to reliably grasp the road surface, so the driving force can be efficiently transmitted to the road surface, and the deformation amount of the small bumps 2 200524760 can be suppressed to be small, so it can be reduced. Rotational resistance. In item 4 of the scope of patent application of the present invention, "the above-mentioned block portion has a corner shape 7 7 and a bicycle tire corner column shape, and the plane constituting the peripheral wall surface is arranged in the direction of travel of the bicycle tire". ′. According to this structure, when the bicycle is running or braking, a load of 2 can be used to constitute the peripheral wall surface 3. The plane of the plane and the whole of the fairy: the party, therefore, the base portion 4 and the block portion 3 are not easily broken. In the "^ 13 patent scope, the sixth to the ninth, the increased tire of the bicycle tire is similar to her pottery position and gradually based on this structure." Compared to the case where the rising angle Θ 2 of the block 3 is 90 degrees, 'The peripheral wall surface 4 of the base portion 4 described above. The angle formed with the peripheral wall surface 30 of the block portion 3 is large, and the standing angle ^ of the base portion 4 is small. Therefore, the ridge of the small protrusions as a whole is larger than the rising angle θ2 of 90 degrees, so the mud is not easy to fill the grooves between the small protrusions 2 and the stuffed mud can be easily discharged. In addition, since the deformation of the block portion 3 can be suppressed to a small extent, abrasion or breakage is unlikely to occur. The bicycle tire claimed in the patent application Nos. 10 to 17 of the present application is "the above-mentioned base portion is a conical seat". According to this configuration, when a load is applied to the small projection 2 from any direction, the 'conical seat can support the block 3 in the same manner. In the bicycle tire of the present invention, please refer to the bicycle tires Nos. 18 to ㈣ of the patent, "The base part is a pyramid seat", and according to this structure, the small protrusions 41a i 41d constituting the pyramid seat are arranged in a predetermined direction. 2 'Therefore, the straight line connecting 胄 c of the base portion 4 and the block portion 3 can be used to withstand 200524760. The strength of the small protrusion 2 in a specific direction can support the load, so it can be improved. (Effects of the Invention) As described above, according to the scope of the patent application, the second system forms a columnar block 3 connected to the dog block ^ ^, and is connected to the two-layer structure which is provided on the wheel surface 10 and has a trapezoidal cross-section. With this configuration, it is possible to reduce the deformation of the block portion to the traveling direction of the pedal wheel 1 without making the small projection 2 "make the height M of the small large block small", so the rotation can be reduced. Increase in resistance or weight of bicycle tire 1. Therefore, it is excellent in walkability and handling. Even in the case of braking or turning, since the peripheral wall surface 40 of the base portion 4 can support the block portion 3, it is not necessary to reduce the area of the block portion 3 in contact with the road surface to stop the feeding protrusion 2 Worn or broken. Therefore, it has excellent braking performance, cornering performance, and durability. The angle formed by the wheel surface 10 and the peripheral wall surface 40 of the base portion 4 and the angle formed by the peripheral wall surface 40 and the peripheral wall surface 30 of the block portion 3 are both obtuse angles 2 and the small protrusions 2 The ditch G is increased toward the front end of the small projection 22, so the small projection 2 does not need to be formed in a tapered shape, and prevents mud filling, and the filled mud can be smoothly discharged. Therefore, the sludge is excellent.

According to the inventions in the 18th to 25th of the scope of the patent application, the base portion 4 is formed into a pyramid seat ', thereby increasing the strength of the small projection 2 to a load in a specific direction, and thus having excellent durability. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. 200524760 (Implementation Mode 1) Figures 1 and 2 are bicycle tires of this embodiment. The structure of bicycle tire 1 is shown in Figure 1. The small projections 2 are projected on the wheel surface 10. The base portion 4 with a trapezoidal cross-section; and the columnar block portion 3 connected to the base portion 4 and in contact with the road surface during driving form a two-layer structure, and the small projections 2 are arranged along the circumferential direction to adapt to off-road The base portion 4 and the block portion 3 are formed so that the peripheral wall surfaces 40 and 30 having different inclination angles are connected to each other via the connecting portion c. The base portion 4 is attached to a bicycle tire! Direction of travel = circle: seat, as shown in Figure 3, the center B of the top surface is;; side: = in the surface: A is to the rear. Therefore, compared to the peripheral wall surface Yang which is located at the front and left and right sides of the travelling direction Γ, the angle θ1 standing up from the wheel surface 10 is small and the amount of inclination is large. In addition, = the peripheral wall formed to the left and the right side ... with the same standing angle, the block 3 is a four-corner with a square cross-section connected to the top surface of the base portion 4. The name of the series of the third wall of the above ㈣3 is gradually inclined toward the wheel surface 10 and has a rising angle center as described above. The block 3 is arranged on a plane 31a, which With respect to the above-mentioned pedal wheel, the lamp advances in a direction, and the planes 3iG and 31d are parallel to the above-mentioned traveling direction. From the iH, the small protrusion 2 is based on the standing angle of the 4 peripheral wall surface 40 of the base portion 01 is 30 degrees, the 02A training library i + m angle Θ3 A center a Μ is 80 degrees, the rising angle of the rear peripheral wall surface 3 is made of 45-degree square silk. In addition, the height 12 200524760 N of the base portion 4 and the height M of the base portion 3 of the block portion 3 are three-fifths and two-fifths of the height Η of the tread surface, respectively. With this configuration, in the example of the bicycle tire, the block 3 having a standing angle 02 close to a right angle can be used to tightly grasp the road surface such as the sloping or muddy ground on which the bicycle is traveling. The height is less than half of the 2 degree of the small projections. Therefore, when the bicycle is driven, the deformation of the small projections 2 in the traveling direction of the block 3 and the opposite direction of the small projections 2 is suppressed to a minimum. Furthermore, the angle at which the base portion 4 rises from the wheel surface 10 is "small, and there is almost no deformation during driving, and at the same time, the block portion 3 connected by the peripheral wall surface 4G having a large amount of inclination can be supported from below. Especially in this In the structure of the example, the frontal i-plane 4Ga has a large inclination, so it can firmly support the above-mentioned block 3 for the load from the forward direction during driving. This is due to the deformation of the small projection 2 The driving resistance can be efficiently transmitted to the road surface, so the driving controllability is excellent. Also, when the load from the direction other than the traveling direction is applied to the small projection 2 during braking or turning, the above The base portion 4 can support the j block 43 to suppress the deformation of the small protrusions 2 and prevent wear or damage, so it has excellent braking performance, cornering performance, and durability. First, it is formed by the peripheral wall surface 4G of the base portion 4 The angle between two = the peripheral wall surface 40 and the contour of the block 3, so as shown in Figure 3, the groove between the small protrusions 2. PG is towards the front end of the small protrusions 2 Excellent. In particular, in the configuration of this example, the block 3 described above 13 200524760 The system is inclined so that the mud is harder to fill, and the stuffed mud is discharged more easily. As described above, in the bicycle tire example 1, the running, handling, braking performance, turning performance, durability, exhaust Any performance such as mudiness is very good. Therefore, it can be widely used in off-road bicycles with different uses or walking conditions. Furthermore, the structure of this embodiment is based on the flat heart of the peripheral wall surface relative to the bicycle tire i. The direction of travel is flat, and the block 3 is arranged in a manner parallel to the direction of travel. Therefore, the negative left and right sides of the direction of travel can be supported by the plane as a whole. Therefore, the escape base portion 4 and the block 3 are not easily broken. In addition, since the base portion 4 is a conical seat, the base portion * ^ can support the block portion 3 to suppress the deformation to a small load in any direction, so the durability is excellent (implementation type) 2) FIG. 4 shows a foot tire 0 with small bumps 2 of different structures. The small bumps 2 in this example are a base part 彳 connecting part 3 formed by a quadrangular pyramid seat, which is the same as the first embodiment. For example, as shown in FIG. 5, the above-mentioned base portion 4 is formed in a manner that the inclination of the peripheral wall surface ^ on the traveling side of the bicycle tire i is large, and the production of the peripheral wall surface θ / ι is smaller than the rear and left and right. The lateral peripheral wall surface only has the rising angle. The peripheral wall surface 40 of the base portion 4 is constructed by the plane 4lai41d14 200524760 and as shown in the figure :: Tuesday surface: flat ... The structure of this bicycle tire example 1 is the same as that of the above-mentioned embodiment 1, when driving with the same resistance wheel i, the turning operation caused by the deformation of the small projection 2 is excellent, and the driving force is efficiently transmitted to the road surface. Therefore, the walkability, as well as the 6th @chain line *, can support the block 刹车 3 by the base portion 4 even when the small projection 2 is deformed during braking or turning. Since the deformation of the small projection 2 can be suppressed to a small value, the braking performance and the turning performance are excellent. In addition, the abrasion or breakage of the small protrusions 2 can be prevented, so the durability is different. Especially in the structure of this example, the above-mentioned planes 31 a Y 31b, 41a, and 41b are arranged with respect to the running direction of the bicycle tires, and the above-mentioned planes 31c, 31d, 41c, and 41d are arranged parallel to the above-mentioned running direction. The protruding block 2 has a higher strength and superior durability compared to the above-mentioned embodiment 丨 with respect to the front, rear, left, and right loads. The grooves G between the small protrusions 2 gradually increase toward the front end of the small protrusions 2, so that it is difficult to fill the grooves G with the mud, and the stuffed mud is smoothly discharged, so the mud drainage is excellent. (Others) The bicycle tire of this embodiment is not limited to the above-mentioned bicycle tire. In the above example, the block portions 3 are all formed in the shape of a quadrangular prism. However, if 15 200524760 is a case where the base portion 4 and the block portion 3 having different standing angles are connected to form two sections, then the block portion 3 may also be Conical, or also conical or polygonal. "', But also the heart part and the outside,-the small cry block side I of the shape of MN ;: the small protrusion 2 of the same shape, so that the side of the bicycle tire has a different pattern. 16 200524760 [Simplified illustration of the figure] Section 1 The figure is a cross-sectional view of a bicycle tire according to Embodiment 1 of the present invention.
