Description

[0001]
[Field of the Invention]
The present invention relates to a bicycle having a saddle and a saddle thereof.
[0002]
[Prior art]
Conventional bicycle saddles contain a cushion member between a saddle base and a saddle top.
A coil spring is provided downward at the rear portion of the lower surface of the saddle base, and a boat line is provided across the tip of the saddle base and the coil spring. The boat line is provided with a yakura for fixing the saddle to the seat post.
[0003]
[Problems to be solved by the invention]
The boat wire and the coil spring are formed of a metal wire and need plating treatment for rust prevention.
Further, even if plating is performed, corrosion due to rust cannot be completely prevented, and there is a case where the erosion portion is broken by an impact. In addition, there is a problem in the material of the metal wire itself, and the wire may be broken even if the corrosion has not progressed.
Metal boat wires and coil springs are heavy. Efforts have been made to reduce the weight of bicycles, especially for electric bicycles that add weight to the battery and motor, but there is no alternative to metal boat wires or coil springs. Was.
[0004]
If the thickness in the height direction of the cushion member interposed between the saddle base and the saddle top is increased to about 50 mm, the same cushioning property can be obtained by omitting the coil spring and the boat line.
However, since the cushion member is only covered with the soft saddle top, when a force acts on the cushion member left, right, front and back, the cushion member cannot be prevented from swinging. For this reason, at the time of petting, each time the rider alternately extends the leg downward, the cushion member also sways to the extended leg side. Accordingly, the center of gravity of the rider moves left and right due to the petering, so that the petering is not stabilized, that is, the running of the bicycle is not stabilized.
The present invention solves the problem of using a coil spring or a metal boat wire and the problem of increasing the thickness of a cushion member at a glance, and provides a bicycle saddle capable of riding comfortably and stably, and the saddle. Bicycles are to be revealed.
[0005]
[Means to solve the problem]
The saddle according to the present invention is a saddle in which the cushion member (4) is accommodated in a space (20) between the saddle base (2) and the saddle top (3), wherein the saddle base (2) and the boat (5) are combined. The saddle base (2) has a downwardly protruding portion (22) which is not easily deformed on both sides of the rear portion of the saddle base (2), and the inside of the protruding portion (22) has no partition with respect to the space (20). The hollow chamber (23) is also filled with the cushion member (4a).
[0006]
[Action and effect]
When the rider of the bicycle straddles the saddle (1), the positions of the coccyx of the rider correspond to the rear sides of the saddle (1). The overall height of the cushion members on both sides at the rear of the saddle base (2) is increased by the thickness of the cushion member (4a) filled in the raised portion (22) of the saddle base (2), and the cushioning property in the vertical direction is increased. Has improved. Therefore, it is possible to prevent a strong impact from acting on the tailbone. The presence of the cushion member (4a) in the raised portion (22) of the saddle base (2) has a cushioning property comparable to that of the conventional saddle base (2) even if the coil spring that elastically supports the entire saddle base (2) is omitted. Can be made.
[0007]
The portion of the cushion material having a greater thickness than before is accommodated in a protruding portion (22) formed integrally with the saddle base (2) and not easily deformed. Left and right and back and forth shaking are prevented. Therefore, the whole cushion member does not sway left and right during petering, and stable petering with little movement of the center of gravity of the rider can be performed, and the running of the bicycle is stabilized.
[0008]
Further, the conventional metal boat wire is a synthetic resin board boat in the present invention, and the conventional metal coil spring is a raised portion (22) of a synthetic resin saddle base (2) in the present invention. Since the cushion member (4a) filled in the raised portion (22) is replaced, it is possible to contribute to weight reduction of the entire saddle. Also, unlike conventional metal boat wires and metal coil springs, plating for rust prevention is not necessary, and there is no problem of breakage due to corrosion.
The raised portion (22) of the saddle base (2) can be integrally formed with the saddle base (2) when the saddle base (2) is injection-molded, and a special process for forming the raised portion (22) is not necessary. Absent.
