Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a bicycle saddle device, and more particularly, to an ergonomic bicycle saddle device that effectively distributes weight to the back and buttocks.
[0002]
[Prior art]
As shown in FIG. 1, the conventional bicycle saddle 11 merely supports the buttocks of the rider. Therefore, during riding, all the gravity from the rider concentrates on the buttocks, causing the buttocks to be compressed. In addition, since no support is given to the back of the rider, there is a drawback that the back is bent by the gravity and hardly exerts force on stepping and braking as shown in FIG.
[0003]
In order to solve the above-mentioned disadvantages, a bicycle saddle device 2 as shown in FIG. 3 is commercially available. The saddle device of this bicycle is fixed to the lower end of a substantially L-shaped seat post 23 having upper and lower ends, and has a riding surface for supporting a buttocks of a rider from below. A backrest 22 fixed to the upper end and having a backrest surface for supporting the back of the rider from behind is provided. The saddle 2 of such a bicycle can support not only the buttocks but also the back of the rider. However, the front edge and the rear edge of the seat 21 are almost in the same horizontal plane, and the backrest 22 of the backrest 22 is provided. Since the surface is almost parallel to the vertical plane facing forward, the gravity from the rider is concentrated vertically on the buttocks during riding, and the back is also bent by the gravity. Therefore, in this bicycle, although the back can be leaned against the back surface of the backrest 22, practically no support is given to the back, so that the buttocks are also pressed.
[0004]
[Problems to be solved by the invention]
In view of the above, an object of the present invention is to provide a bicycle saddle device that can effectively support not only the buttocks but also the back, and can improve the comfort of riding. .
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention relates to a seatback having a backrest surface at each of the upper and lower ends of a substantially L-shaped seat post for supporting a back of a rider from behind, and a backrest for supporting a buttocks of a rider from below. In a bicycle saddle device in which a seat having a surface is fixed, a front edge of the riding surface is slightly higher than a rear edge, and an upper edge of the backrest is slightly biased behind a lower edge. The present invention provides a saddle device for a bicycle.
[0006]
In the saddle device for a bicycle according to the present invention configured as described above, the front edge of the riding surface of the seat is slightly higher than the rear edge, and the upper edge of the backrest surface is slightly biased behind the lower edge. Thereby, when the rider is seated on the seat, the center of gravity falls on the rear edge of the seat, the body leans a little by this, and the back can lean against the backrest surface. In addition to being dispersed on the buttocks and the back, pedaling and braking can be performed smoothly while the back is kept close to the backrest surface, so that the riding comfort can be improved.
[0007]
The seating surface of the seat in the bicycle saddle device of the present invention preferably has a depression in which the arc fits the buttocks and the weight applied thereto can be evenly distributed. Therefore, the present invention further provides a seat back having, at the upper and lower ends of the substantially L-shaped seat post, a backrest that supports the back of the rider from behind and a seating surface that supports the buttocks of the rider from below. In the saddle device for a bicycle, the riding surface is gradually depressed rearward from the front edge, and then rises so as to have a rear edge slightly lower than the front edge, and the backrest surface is the lower end. A saddle device for a bicycle, characterized in that it stands up slightly backward from the edge.
[0008]
The saddle device of the bicycle configured as described above not only disperses gravity to the buttocks and the back during riding, but also the riding surface gradually sinks backward from the front edge, and is slightly lower than the front edge. Since the rear edge rises, the buttocks are completely brought into contact with the riding surface, and the gravity can be evenly distributed to the left and right sides of the buttocks, so that the comfort of riding can be further improved. .
[0009]
[Embodiment of the invention]
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 4 and 5, the bicycle saddle device 3 according to the present embodiment is attached to a standing pipe 300 that rises obliquely rearward from a position slightly biased backward in the center of the bicycle frame 30. The saddle device 3 includes a substantially L-shaped seat post 6 having upper and lower ends, which is fixed to a lower end 61 of the seat post 6, and which supports a rider's buttocks from below. The seat further includes a seat 4 having a surface 43 and a backrest 5 fixed to the upper end 62 of the seat post 6 and having a backrest surface 53 for supporting the back of the rider from behind.
[0010]
When FIG. 6 is combined with FIG. 5, the riding surface 43 is gradually depressed backward from the front edge 41 and then rises so as to have a rear edge 42 slightly lower than the front edge 41. That is, the front end edge 41 of the riding surface 43 is slightly higher than the rear end edge 42, and has a depression matching the arc of the buttocks. According to the gravity distribution experiment of the buttocks, it is better that the front edge 41 of the riding surface 43 rises about 12 to 18 degrees from the horizontal plane X including the rear edge 42, but in the present embodiment, 15. 63 degrees.
[0011]
The upper edge 51 of the back surface 53 is slightly biased behind the lower edge 52. Then, according to the gravity distribution experiment of the buttocks, it is preferable that the upper edge 51 of the backrest surface 53 be separated from the front vertical plane Y including the lower edge 52 by about 12 to 18 degrees, but in this embodiment, , 15.63 degrees.
[0012]
As shown in FIG. 7, when the rider is seated on the seat 4, the front edge 41 of the riding surface 43 rises 15.63 degrees from the horizontal plane X including the rear edge 42, so that the center of gravity is on the seat 4. 4 and the body thereby leans slightly backwards, allowing the back to lean against the back surface 53 of the back 5 during riding, so that gravity can be distributed to the buttocks and back. . In addition, since the riding surface 43 is a depression corresponding to the buttocks arc, the buttocks can be completely brought into contact with the riding surface 43, and the gravity can be evenly distributed to the right and left sides of the buttocks. Therefore, during riding, the buttocks and the back can be effectively supported. Further, since the gravity is dispersed to the buttocks and the back, as shown in FIG. 8, a force is easily applied to the stepping and braking, and the riding comfort can be improved satisfactorily.
[0013]
[Effect of the invention]
As described above, in the bicycle saddle device according to the present invention, the front edge of the riding surface of the seat is slightly higher than the rear edge, and the upper edge of the backrest surface is slightly biased behind the lower edge. When the rider is seated on the seat, the center of gravity falls on the rear edge of the seat, and the body is thereby slightly tilted backward, so that the back can lean against the backrest surface. In addition to being dispersed on the back, the pedal can be smoothly stepped and braked while the back is kept close to the backrest surface, so that the riding comfort can be improved. Further, the seating surface of the seat is indented so that the arc fits the buttocks and the weight applied thereto can be evenly distributed. Since they can be dispersed, the comfort of riding can be further improved.
