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 on a back and a buttock.
[0002]
[Prior art]
As shown in FIG. 1, the conventional bicycle saddle 11 merely supports the rider's buttocks, so that during the ride, all the gravity from the rider is concentrated on the buttocks and presses the buttocks, In addition, since it does not give any support to the back of the rider, as shown in FIG. 2, there is also a drawback that the back is bent by its gravity and it is difficult to exert force on the stepping and braking.
[0003]
In order to solve the above drawbacks, a bicycle saddle device 2 as shown in FIG. 3 is commercially available. The saddle device of the bicycle is fixed to the lower end of a substantially L-shaped seat post 23 having upper and lower ends, and has a seat 21 having a riding surface that supports a rider's buttocks from below, and the seat post 23 A backrest 22 fixed to the upper end and having a backrest surface that supports the back of the rider from behind is provided. Such a bicycle saddle 2 can support not only the buttocks of the rider but also the back, but the front edge and the rear edge of the seat 21 are substantially on the same horizontal plane, and the backrest 22 has a backrest. Since the plane is almost parallel to the forward-facing vertical plane, during riding, the gravity from the rider concentrates vertically on the buttocks, so the back also bends due to the gravity. Therefore, in this bicycle, although the back portion can be brought close to the backrest surface of the backrest 22, practically no support is given to the back portion, so the hip portion is still compressed.
[0004]
[Problems to be solved by the invention]
In view of the above, an object of the present invention is to provide a saddle device for a bicycle that can effectively support not only the buttocks but also the back, and can improve the riding comfort. .
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a backrest having a backrest surface that supports the back of the rider from behind at the upper and lower ends of a substantially L-shaped seat post, and a rider that supports the rider's buttocks from below. In a bicycle saddle device in which a seat having a surface is fixed, a front end edge of the riding surface is slightly higher than a rear end edge, and an upper end edge of the backrest surface is slightly behind a lower end edge. A bicycle saddle device is provided.
[0006]
In the bicycle saddle device of the present invention thus configured, the front end edge of the riding surface of the seat is slightly higher than the rear end edge, and the upper end edge of the backrest surface is slightly behind the lower end edge. Thus, when the rider sits on the seat, the center of gravity falls to the rear edge of the seat, and the body can tilt slightly backwards, and the back can be brought close to the backrest surface. Not only is it distributed to the buttocks and the back, but also the pedaling and braking can be performed smoothly with the back approaching 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 is preferably a depression that allows the arc to fit the buttocks so that the weight applied thereto can be evenly distributed. Accordingly, the present invention further provides a seat having a backrest having a backrest surface supporting the back of the rider from behind and a riding surface supporting the buttocks of the rider from below at the upper and lower ends of the substantially L-shaped seat post. In the bicycle saddle device, the riding surface is gradually recessed from the front edge to the rear, and then rises so that the rear edge is slightly lower than the front edge, and the backrest surface is the lower edge. Provided is a bicycle saddle device characterized by standing up slightly from the edge.
[0008]
The bicycle saddle device configured in this way not only distributes gravity to the buttocks and the back during riding, but the riding surface gradually sinks backward from the front edge, and is slightly lower than the front edge. Since it stands up so that the rear edge becomes, the buttock can be completely applied to the riding surface, and the gravity can be uniformly distributed on the left and right sides of the buttock, so that the riding comfort can be further improved. .
[0009]
[Embodiment of the Invention]
Hereinafter, more 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 this embodiment is attached to a standing pipe 300 that rises obliquely backward from a position slightly deviated to the rear of the central portion of the bicycle frame 30. The saddle device 3 includes a substantially L-shaped seat post 6 having both upper and lower ends, and is fixed to a lower end 61 of the seat post 6 and supports a rider's buttocks from below. 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 that supports the back of the rider from behind are further provided.
[0010]
Further, when FIG. 6 is combined with FIG. 5, the riding surface 43 gradually rises backward from the front end edge 41 and then rises so that the rear end edge 42 is slightly lower than the front end edge 41. That is, the front end edge 41 of the riding surface 43 is slightly higher than the rear end edge 42 and is a recess that matches the arc of the buttocks. According to the gravity distribution experiment of the buttocks, the front end edge 41 of the riding surface 43 should rise from about 12 to 18 degrees from the horizontal plane X including the rear end edge 42. In this embodiment, however, 15. It was set to 63 degrees.
[0011]
Further, the upper end edge 51 of the backrest surface 53 is slightly behind the lower end edge 52. According to the gravity distribution experiment of the buttocks, the upper end edge 51 of the backrest surface 53 should be separated from the forward vertical plane Y including the lower end edge 52 by about 12 to 18 degrees, but in this embodiment, 15.63 degrees.
[0012]
As shown in FIG. 7, when the rider sits on the seat 4, the front end edge 41 of the riding surface 43 rises 15.63 degrees from the horizontal plane X including the rear end edge 42, so that the center of gravity is 4 falls to the rear edge 42 of the body, and the body tilts back slightly, so that the back can be brought close to the backrest surface 53 of the backrest 5 while riding, so that gravity can be distributed to the buttocks and back. . In addition, since the riding surface 43 is a depression that matches the arc of the buttocks, the buttocks can be completely applied to the riding surface 43, and gravity can be uniformly distributed on the left and right sides of the buttocks. Therefore, it is possible to effectively support the buttocks and the back during riding. Furthermore, since gravity is distributed to the buttocks and the back, as shown in FIG. 8, it is possible to easily apply force to the stepping and braking, and to improve the comfort of riding.
[0013]
[Effect of device]
As described above, in the bicycle saddle device according to the present invention, the front end edge of the riding surface of the seat is slightly higher than the rear end edge, and the upper end edge of the backrest surface is slightly behind the lower end edge. When the rider sits on the seat, the center of gravity falls to the rear edge of the seat and the body tilts back slightly, so that the back can be brought close to the backrest surface, so that gravity can be applied during riding. In addition to being distributed to the back portion, the pedaling and braking can be performed smoothly with the back portion approaching the backrest surface, so that the riding comfort can be improved. In addition, the seating surface of the seat is a depression that allows the arc to fit the buttock and the weight applied to it is evenly distributed, so that the buttock is completely applied to the riding surface and the gravity is evenly distributed on the left and right sides of the buttock. Since it can be dispersed, the comfort of riding can be further improved.
