Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle or seat used for supporting a user of a device such as a bicycle, a tricycle or an exercise machine which obtains a power source from a foot or a leg of a rider.

[0002]

Cycling is a useful and rewarding exercise for many people. Bicycles provide not only recreation and exercise but also transportation, among others. Conventional seats, which are attached to most bicycles in use today, are designed in one piece and consist of a wide part for sitting and a narrow "corner" part. This horn-shaped protrusion is located in front of the seat to allow the rider's legs to move upward in the seat to make pedaling more comfortable.

One of the problems with conventional seats for pedal operating devices is the inability to provide the rider with adequate comfort. The conventional seat supports the rider's weight inefficiently and causes considerable friction between the seat and the rider's legs. This makes the rider uncomfortable, and limits the amount of time that the rider can ride the bicycle within a time range in which the rider can be patient. In addition, some people find it particularly uncomfortable to ride a bicycle for a short time, especially those who are old, heavy, and suffer from symptoms such as hemorrhoids.

Conventional seats are designed to slide the rider's legs down along the sides of the seat. This requires that the angled projections be made small in order to secure a passage for the legs. However, since the seat has to support the rider of the bicycle, the supporting portion of the seat is set to be larger than the angular protrusion, and the upper thigh is placed under the rider's hip. Larger seats are designed to provide more support for the rider, but such seats also limit rider movement, causing more friction and causing discomfort to the rider. become.

Attempts have been made to solve the above-mentioned problems of the conventional seats. A sheet having two divided members or a divided sheet is designed in various forms, some of which have an adjustable sheet width, and some of which have or do not have angular protrusions. Alternatively, there is a type in which a member divided into two parts is moved up and down as the rider's legs move up and down.

Furthermore, as disclosed in US Pat. No. 4,541,668, proposed by Luau, while one of the two split members is biased downward by the rider's pedaling action. Has a design in which the other member is mechanically moved upwards. Other designers have been careful to design components to more uniformly support the rider's weight, as disclosed by Baker et al. In U.S. Pat. No. 4,387,925. Design to reduce the friction between the rider's legs and the horns by specially modifying the horns, as disclosed in U.S. Pat. No. 4,512,608, which Ernerni proposes. Has been done.

[0007]

According to the seat described above, the comfort can be improved to some extent, but all the points required for the pedal operating device seat cannot be satisfied. Traditional seats are totally unacceptable to some people, and some types are unacceptable. Although a split seat without angular projections is a clear improvement, no seat has yet been designed that fully meets the cyclist's requirements for comfortable and effective seats. Therefore, the pedal operating device seat of the present invention has been made in view of the above-mentioned problems, and an object thereof is to reduce friction between a rider and a seat during riding. Another object of the present invention is to provide a vehicle seat that can move in three different directions during the paddling operation to reduce friction between the rider and the seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention is shown in FIGS.
2B and FIGS. 3 and 4. FIG. 1A is a perspective view of the first embodiment of the present invention. 2A is a front view of the first embodiment of FIG. 1A, and FIG. 3 is an exploded view of the embodiment of FIGS. 1A and 2A, omitting the supporting portion.

Referring to FIGS. 1 to 3, a bicycle seat assembly 10 includes left and right seat bodies 12 and 14 that are identical to each other. These left and right sheet bodies are shaped so as to generally follow the contours of the buttocks and upper thighs of the human body. Attachment means 16 is used to attach the seat assembly described above to a bicycle or other device. The mounting means 16 is, for example, inserted into the receiving side of the mounting column as shown in FIGS. 1A and 2A for a bicycle (not shown) or other device. As shown in FIGS. 1B and 2B, the attachment means 16 can also be made from a flexible material that is larger in shape than the outline of a standard seat strut (shown by the dashed lines in the figure). The mounting means 16 may also include a seat post receiving portion 19 into which the seat post 17 is inserted. This attachment means 16 is subsequently fixed to the seat column using known fastening means, for example a nut and bolt combination 5.

The shaft body 18 passes through the shaft body mounting hole 21 and the column cover member 20, and is attached to the column cover member 20 by mounting bolts 22 and other fastening means. The sheet bodies 12 and 14 are attached to the shaft body 18 as described with reference to FIGS. 4 and 5 described later, and are made swingable around the longitudinal axis of the shaft body 18. There is.

As can be seen from FIGS. 1 to 3, the mounting bolts 22 for the support column cover member penetrate the terminal end of the support column cover member 20, penetrate the shaft 18 and are screwed into the mounting means 16. There is. The bearing 24 and the washer 26 are attached to this mounting means 16
May be provided between the column support member and the column cover member 20 to provide smoother rotation of the column cover member.
The washer 26 may be omitted.

The column cover member 20 is directly attached to the mounting means 1.
6 may be attached. In addition, the support lid member 20 and the shaft body 18 are attached to the mounting means 16 by a bearing 24 and a washer 26.
When the support member 20 is loosely attached with or without the support member 20, the support member 20 and the shaft member 18, and the sheet members 12 and 14 are attached to the assembly member 1 as a whole.
It becomes rotatable around the 6 axis. Therefore, the cotter pin 28 prevents the mounting bolt 22 from rotating carelessly so that only the column cover member 20 can rotate.

Next, FIGS. 4 and 5 are a side view and a bottom view of the sheet body of the first embodiment shown in FIGS. 1 and 2, respectively. Preferably, the rear part of the sheet body 12 of FIGS. 1 and 2 is heavier than the front part. By making the weight distribution non-uniform in this way, the above-mentioned sheet body is set screw 5 when the load is not acting on the sheet body.
4 can be urged to move with respect to the back surface of the slot 52 provided with 4. On the other hand, since the sheet body 14 is formed completely symmetrically with the sheet body 12, the above-described mounting method can be applied.

The shaft body 18 is a bearing insertion portion 50 of the seat body 12.
Can be inserted into. Slot 52 of sheet body 12
Is provided with a screw 54 (such as a set screw) so that a part thereof is screwed onto the shaft body 18,
The sheet body can be rotatable within a range where the screw 54 can move within the slot 52. In this way, the sheet body 1
The length of the slot 52 is determined in order to set the rotation amount by which the 2 rotates about the shaft 18. Also, the screw 54
Is preferably provided long enough so that the tip portion thereof protrudes from the bottom surface of the sheet body 12 to regulate the above rotation.

The operation of the seat assembly 10 described with reference to FIGS. 1 to 5 will be described with reference to FIGS. 6 to 8. Figure 6
FIG. 6 is a perspective view of the embodiment described in FIGS. 1 to 5, showing a state in which a rider on the seat assembly 10 has moved the left and right paddles to the 12 o'clock and 6 o'clock positions. 7 and 8 (a rider is omitted) are a side view and a top view of the seat position in a part of the pedaling operation, respectively. When the rider is in the position shown, the left leg is fully extended, while the right leg is in a state of starting to push down the pedal downward.

The left seat body 12 of the seat assembly 10 moves backward and moves downward due to the movement of the left thigh due to the pivotal support portions of the seat described above. As a result, between the left foot and the left seat body 12. Almost no friction occurs. Also,
The supporting shaft 18 retracts toward the rear of the center line of the bicycle as the seat assembly rotates about the mounting means 16, and the left seat 12 also moves toward the rear of the center line of the bicycle, similarly. Since the vehicle rotates around the body 18, the rider's weight is substantially evenly distributed on the left seat body 12.

At this time, most of the weight of the riders of men and women is supported by the left leg, and it is not necessary to support the left seat body 12 of the seat, so that the left seat body 12 is far away from the left leg. As described above, since the weight is evenly distributed and the pressure generated on the rider's legs and buttocks during riding can be removed, there are no pressure points that bother the rider. The operation opposite to the operation described above is performed simultaneously (12:00 and 6
Occurs on the bicycle, seat and right side of the rider (in the time position). That is, the right seat body 14 is directed upward and forward in the bicycle traveling direction, and the weights of the rider's buttocks and legs are substantially evenly distributed to the right seat body 14.

As will be apparent from FIGS. 6-8 and the above description, seat assembly 10 is in constant condition as it is directly involved in the rider's motion during pedaling. Since the seat assembly 10 operates along with the movements of the rider's legs and buttocks during pedaling, the seat assembly 10 is supported when support is required, and is retracted when support is no longer required. The seat assembly 10 can maintain a substantial contact with the rider's leg and buttocks at the same point during the entire pedaling operation. By operating in this way, the friction between the rider and the seat can be reduced, so that the rider can be further comfortable.

Are provided so as to penetrate through the mounting holes 123 of the support column lid member that are formed perpendicularly to the surface portion 125 of the mounting means 116.

As described above, the upper end 11 of the mounting means 116
Since 7 is cut obliquely, the surface portion 125 has an elliptical shape as shown in FIG. 9B. According to this configuration, the seat assembly 110 has the effect of always being positioned at the optimum position when the rider is not placed. That is, most of the weight of the seat is directed toward the rear of the bicycle, so that the seat is naturally swung by the action of gravity so that the front part of the seat is directed forward and the rear part of the seat is directed rearward. When using the above configuration, the longest part of the attachment means 116 is positioned so as to face forward as shown in FIG.
