Description

[Detailed Description of the Invention] The present invention relates to an improvement of a saddle for a bicycle, motorcycle, etc. using a board boat.

Conventionally, this type of saddle includes one using a straight boat made of steel wire and one using a plate boat made of steel plate. However, in the case of a line boat, the material itself is expensive and the cost is very high, and in the case of a board boat, the material itself is cheaper and easier to process than a line boat, and it can be made lighter, but the design There were limitations and drawbacks such as poor durability.

That is, in the conventional board boat type, as shown in FIG.
2' and 32', and are rotatably pivoted by caulking with pins 4' and 4', respectively. In this case, while the board boats 1' and 2' are fixed to the frame of a bicycle or the like, torsional stress is applied to the saddle base 3' in response to the shift of the rider's weight, etc. ', 2' cannot exhibit the torsional absorption effect like a line boat, and the torsional stress applied to the saddle base 3' acts directly on the caulked portions of the peripheral walls 32', 32' and the pins 4', 4'. , there was a risk that the caulked portion and the pins 4', 4' would be cracked or damaged.

In addition, like the conventional saddle, the thickness of the entire saddle is thick, and the peripheral wall portions 32', 3 of the saddle base 3' are thick.
In the case where the height H of 2' is formed high, the saddle base itself exhibits a moderate torsion absorption effect and can prevent cracks and damage in the caulked parts to some extent, but as with recent saddles, the overall thickness of the saddle If the saddle base is thin and the peripheral wall of the saddle base is formed low, the saddle base itself cannot be expected to have a torsion-absorbing effect, and the caulked parts are bound to crack or break, resulting in poor durability and lower product value. It will be low. In other words, in order to attach the tip of the board boat in close contact with the inner surface of the tip circumferential wall of the saddle base as in the past, it is necessary to increase the height H of the tip circumferential wall of the saddle base, and also, In order to reduce the torsional stress applied to the peripheral wall at the tip, it is necessary for the saddle base itself to absorb the torsional stress at the tip, which requires the saddle base to be formed deeply, making the saddle base larger than necessary. Due to design constraints, it cannot be used for modern light and sports cars, and for this reason, board boat-type saddles are not in practical use today.

In view of these points, the present invention takes advantage of the advantage of the material itself, which is inexpensive and lightweight, to prevent cracks and damage to the surrounding wall of the saddle base, improve durability, and increase product value. The purpose is to put a high, board-shaped saddle into practical use.

That is, in the present invention, a pivot is provided between the circumferential walls that face each other on the left and right sides on the lower surface of the distal end of the saddle base, and on this pivot, a pair of planks are provided at the intermediate part of the shaft apart from the inner surfaces of both the circumferential walls. The tip of each boat is rotatably supported, and a distance regulating means is provided between the tip of each boat and the inner surface of the peripheral wall to regulate the distance between the two, and the rear end of each boat and the saddle base are provided. A spring is provided between the bottom surface of the rear end and a mounting portion for attaching to a bicycle or the like is provided at the intermediate portion of each board.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the figure, numerals 1 and 2 are plate boats, which are formed into mutually symmetrical shapes by press working of metal plates such as steel plates, and have pivot notches 11 and 21 at their tips, respectively. Connecting part 1
2, 22 are provided, elongated holes 13, 23 for attachment to a bicycle or the like are provided in the intermediate portion, and holes 14, 24 for attachment of a spring or the like are provided in the rear end portion. The notches 11, 21
has a coaxially corresponding pivot portion 11 at its bottom.
a, 21a, one notch 11 is the pivot part 11
The positions of the openings 11b and 21b are shifted from each other in the front and rear so that the notch 21 opens forwardly and downwardly from the pivot point 21a, and the other notch 21 opens backwardly and downwardly from the pivot portion 21a.

On the other hand, the saddle base 3 includes a seat part 31 that is approximately chestnut-shaped in plan by press working of a metal plate such as a steel plate, and a peripheral wall part 3 that continues downward from the periphery of the seat part 31.
2, and shaft mounting parts 33, 34 are provided on the peripheral wall parts 32, 32 facing each other on both the left and right sides on the lower surface of the tip, and spring mounting parts 35, 36 are provided on the lower surface of the rear left and right sides. Provided integrally, the seat portion 3
A plurality of cover locking pieces 37 are integrally cut and raised on the periphery of the cover 1 or on the peripheral wall portion 32.

The board boats 1 and 2 and the saddle base 3 are each molded separately, and are individually painted and plated as required.

Therefore, when assembling the saddle, first, a pair of spacers 4 are attached to the pivot 4 as space regulating means.
1 and 42 are fitted, both ends of the pivot shaft 4 are engaged with the shaft mounting portions 33 and 34 of the saddle base 3 and fixed by caulking, screwing, or the like. The spacers 41 and 42 are usually made of synthetic resin such as nylon or metal and are formed into a cylindrical shape.

Next, the pivot notch 1 at the tip of each board boat 1, 2
1 and 21 are individually engaged with the pivot shaft 4 between the spacers 41 and 42, the tips of the respective plates 1 and 2 are moved inwardly from the inner surfaces of the peripheral walls 32 and 32 at the tips of the saddle base 3. Connecting portions 12 and 2 are rotatably supported on a pivot shaft 4 at predetermined intervals S and S, and are provided near the tips of both planks 1 and 2.
The two pieces are connected using a fastener 15 such as a screw. After that, springs 5 and 6 are attached between the rear ends of the boats 1 and 2 and the lower surface of the rear end of the saddle base 3. In this case, one end of the springs 5, 6 is locked to the spring mounting parts 35, 36 of the saddle base 3, and the other end is fixed to the spring mounting holes 14, 24 at the rear end of the board boats 1, 2 with a fastening device such as a screw. 71 and 72, and at the time of attachment, 7 is simultaneously attached between the rear ends of the boat boats 1 and 2. In addition, the elongated hole 13 in the middle part of the board boats 1 and 2,
A member such as the tower 8 is attached to 23 via the chrysanthemum bolt 81, nut 82, and chrysanthemum seat 83. Incidentally, one end of the springs 5 and 6 may be attached to the saddle base 3 using a fastener such as a bolt or a nut.

A cushion material 9 is provided on the upper surface of the saddle base 3.
1 is placed or attached, a cover 9 is placed on the saddle base 3, and the periphery of the cover 9 is fixed by cover locking pieces 37 provided on the back surface of the saddle base 3. The cushion material 91 and the cover 9 may be attached after the plates 1 and 2 and the springs 5 and 6 are attached to the saddle base 3, but according to this embodiment, the plates 1 and 2 are attached to the saddle base 3. Since a structure is adopted in which the tip is engaged with the pivot shaft 4 provided on the saddle base 3 through the notches 11 and 21, the cushion material 91 and the cover 9 are attached to the saddle base 3 first, and then the planks 1 and 2 are attached. This allows the cushion material 91 and the cover 9 to be easily attached.

When the saddle configured as described above is attached to the frame of a bicycle or the like, the boards 1 and 2 are integrally fixed to the frame by the tower 8 etc., and the saddle base 3 is attached to the board 1 and 2 with a pivot 4. and springs 5 and 6. In this state, if a load is applied to the saddle base 3 due to the rider's weight or the bounce of the vehicle body, the saddle base 3 will swing around the pivot 4 and the cushioning effect of the springs 5 and 6 will be exerted, and the following will occur. As a result, ride comfort is improved. Furthermore, when torsional stress is applied to the saddle base 3 due to the rider's weight shifting, etc., the saddle base itself exerts a torsion-absorbing effect because the saddle base 3 is formed wide at the rear end of the saddle. In addition, the cushioning action of the springs 5 and 6 is also exerted, and the torsional stress is absorbed. On the other hand, at the leading end of the saddle, although the width of the saddle base 3 is narrow, the pivot notches 11 and 21 at the leading ends of the board boats 1 and 2 are engaged and supported in the middle part of the pivot shaft 4. This pivot 4 and notch 11,
Due to the clearance with 21, the tip of the saddle base and the pivot 4 become integral and can swing up and down as shown by arrow A in Figure 4, and this swing absorbs the torsional stress applied to the tip of the saddle base. The peripheral wall portion 32 of the leading end of the saddle base,
32 is prevented from cracking or being damaged. In addition, the board boats 1 and 2, in which the connecting parts 12 and 22 are connected by the fastener 15, are connected to the pivot shaft 4 by the spacers 41 and 4 at the tip of the saddle base 3.
2, it is pivoted inwardly from the inner surfaces of the peripheral walls 32, 32 at a predetermined distance s, s so that it does not move on the shaft, so it is fixed even against left and right movement in the horizontal plane of the saddle. and no rattling will occur.

By the way, in the above embodiment, the tips of the board boats 1 and 2 are engaged with and pivoted to the pivot 4 by the notches 11 and 21, but the opening positions of both the notches 11 and 21 are shifted from each other. In addition, both the planks 1 and 2 are aligned with each other so as to face each other laterally by connecting the rear ends of the bridge 7, etc., attaching the intermediate portion to a bicycle, etc., and further connecting each other near the tip. The notches 11 and 2 at the tip of the boat are integrated.
1 will never come off axis 4.

In the above embodiment, after the tips of the plates 1 and 2 were individually pivoted on the pivot 4, the tips of the plates 1 and 2 were connected to each other by the fasteners 15. It is not particularly limited, and
The tips of the planks do not necessarily need to be connected.

As explained above, according to the present invention, by using a board boat, the cost of materials can be lowered compared to the case of a line boat, and the tip of the board boat is provided between the front end circumferential wall of the saddle base. Since the saddle is pivoted at the middle of the pivot, the height of the surrounding wall of the saddle base can be lowered, the entire saddle base can be made thinner, and it is also possible to mold the saddle base into a three-dimensionally curved shape. , it is possible to eliminate design constraints and form it into any shape. Moreover, it allows for appropriate swinging of the axis relative to the board boat,
This rocking can absorb the torsional stress applied to the circumferential wall at the tip of the saddle base, preventing cracks or damage from occurring on the circumferential wall at the tip, greatly improving the durability of the saddle base and increasing its product value. Therefore, it is possible to put a board boat type saddle into practical use.
