Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a saddle attached to a bicycle, motorcycle, etc.

(Prior Art) Usually, a boat line forming a mounting portion of the saddle is attached to the saddle base, and a coil spring is interposed between the boat line and the saddle base. Conventionally, a bolt for attaching a coil spring is provided protruding from the back of the saddle base, and a hook-shaped end formed at one end of the coil spring is fitted onto the bolt, and the nut is tightened to secure the one end of the coil spring. was installed on the saddle base. However, fitting the nut onto the bolt located inside the coil spring and tightening it requires special tools and skilled techniques, so it has long been desired to have a structure that allows for easy installation. .

For this reason, as shown in Japanese Utility Model Application Publication No. 55-73484, a seat part consisting of an arc-shaped peripheral wall and a presser piece protruding from the upper part is provided on the back surface of the saddle base. After inserting the hook-shaped end portion into the peripheral wall with the coil spring tilted diagonally through the formed opening, the coil spring is straightened and fixed to the boat line, thereby attaching the coil spring to the saddle base. Installation is in progress. However, with this configuration, the coil spring must be tilted diagonally to fit the hook-shaped end portion, so the coil spring cannot be installed with the coil spring and boat line fixed in advance, and the bolts and nuts cannot be attached. After the coil spring is loosened and the coil spring is attached to the catch, the coil spring and boat line must be fixed again, making the installation work complicated. Especially in the case where the spring member is integrally connected to the rear end of the boat line, it is not possible to tilt only the spring member, and the mounting hole of the catch for attaching the spring member must be made larger. No. In addition, since the hook-shaped end inserted into the seat is partially abutted against the peripheral wall of the seat and the holding piece, when the saddle receives a load, a force is applied to this part. acts in a concentrated manner, and the hook-shaped end part and the catch seat part strongly rub against each other, producing noise, and the catch part is easily damaged or the hook-shaped end part easily falls off from the catch seat part. There was a problem.

(Purpose of the invention) The present invention was made in order to solve the above problems, and can be easily attached to the saddle base without using special tools or tilting the spring member. A bicycle that can stably lock a member to a saddle base, and can prevent the generation of noise, damage to the holding part of the saddle base, and the terminal part of the spring member falling off from this holding part. The company provides saddles such as:

(Structure of the invention) The invention comprises a saddle base made of elastic synthetic resin, a boat line attached to the lower surface of the saddle base, and a spring member provided at the rear end of the boat line. The saddle has a pair of front and rear upright walls on the back surface of the saddle base, and a top plate connecting the tips of the two upright walls, and at least one side end in the left and right direction is open and the spring member is attached to the saddle base. A holding part is provided protrudingly provided with a mounting hole into which the terminal part of the spring member is inserted, and a locking part for preventing the spring member from coming off is provided protrudingly at a position away from the holding part and facing the opening part. A space is formed near the mounting hole in which the end portion of the spring member can be fitted into the mounting hole while the saddle base is elastically deformed and curved in a direction that causes the peripheral portion of the saddle base to protrude toward the surface of the saddle. The distance between the holding part and the locking part and the height of the locking part are set so that

(Example) In Fig. 1, reference numeral 1 denotes a saddle base made of a synthetic resin material having elasticity such as nylon resin. The surrounding wall portion 3 is integrally formed by injection molding or the like. The outer peripheral surface of the saddle base 1 is covered with an outer cover 4 made of vinyl resin or the like, and a cushion material made of foamed urethane or the like is interposed between the seat portion 2 and the outer cover 4.

The seat part 2 of the saddle base 1 is formed with a seat part 7 at the tip of the back surface into which the tip of the boat line 6 is inserted and locked, and on the left and right of the rear end there are coils as shown in FIG. Holding portions 10 into which terminal portions 9 of springs 8 are fitted and held are each integrally formed.
The holding part 10 has a pair of upright walls 11, 11 in the front and back.
and a top plate 12 that connects the tips of the upright walls 11, 11 to form a tunnel shape, and has a width and height large enough to allow the terminal portion 9 to be inserted into the tunnel; A mounting hole 13 is provided whose outer end in the left and right direction is open. That is, the width of the mounting hole 13 is formed to be slightly larger than the outer shape of the end portion 9 formed by circularly curving the tip of the coil spring 8, and the height of the mounting hole 13 is slightly larger than the wire diameter of the coil spring 8. It is formed.

On the outside of the holding part 10, a locking part 14 is provided which abuts the rear end of the terminal part 9 inserted into the mounting hole 13 and locks the coil spring 8 to prevent it from coming off. The opening is provided in a protruding manner opposite to the opening at a position away from the opening. The distance W between the holding part 10 and the locking part 14 and the height H of the locking part 14
As shown in FIG. 3, the seat portion 2 of the saddle base 1 is elastically deformed and curved in a direction that causes the peripheral portion of the saddle base 1 to protrude toward the surface of the saddle, and then the end is inserted into the mounting hole 13. The size is set to form a space into which the portion 9 can be inserted. That is, by curving the saddle base 1, the holding portion 10
By shifting the position of the locking portion 14 in the height direction and expanding and deforming the distance W to W ₁ , the locking portion 14 is Its position and height H are set so that it does not get in the way. Therefore, if the distance W between the holding part 10 and the locking part 14 is made larger than in the illustrated example, the height H of the locking part 14 can be made a little higher, and conversely, if the distance W is made smaller, the height H of the locking part 14 can be made a little higher. It is necessary to keep the height H of the locking portion 14 lower than in the illustrated example. Further, since the curvature of the seat portion 2 changes depending on the strength of the saddle base 1, the distance W and the height H of the locking portion 14 are set to optimum values according to this curvature.

In the above configuration, the first step is to assemble the saddle.
As shown in the figure, after inserting the tip of the boat line 6 into the seat part 7 with the coil spring 8 fixed together with the coil spring 15 through the bolt 16 and nut 17 over the rear end of the boat line 6, the above-mentioned Saddle base 1 to 3rd
As shown in the figure, the coil spring 8 is held in a curved state using a jig or the like, and the end portion 9 of the coil spring 8 is inserted into the attachment hole 13 from the outside of the holding portion 10. in this case,
By using the elasticity of the coil spring 8 to expand and deform the coil spring 8 so that the left and right coil spring end portions 9, 9 are expanded outward from the saddle, both end portions 9, 9 are held at the holding portion 10 at the same time. It can be kept inside. Further, by providing a tapered surface for guiding the terminal portion 9 at the insertion side end of the attachment hole 13, the terminal portion 9 can be inserted more smoothly.

In this way, with the seat portion 2 curved by utilizing the elasticity of the saddle base 1, the holding portion 10 is
Since a space is formed in which the end portion 9 of the coil spring 8 can be inserted into the mounting hole 13 of The end portion 9 of the coil spring 8 can be easily inserted into the attachment hole 13 and attached to the holding portion 10. Moreover, if the saddle base 1 is returned to its original shape after performing the above-mentioned installation work, the locking part 14 will come into contact with the rear end of the terminal part 9, and this terminal part 9 will be inserted into the holding part 10. It will be maintained stably. That is, the terminal portion 9 is firmly held in contact with the inner surfaces of both upright walls 11 of the holding portion 10, the wall surface of the top plate 1, the wall surface of the locking portion 14, and the lower surface of the saddle base 1, respectively. It becomes. Moreover, when using the saddle,
Since the load mainly acts in the direction in which the peripheral part of the saddle base 1 is pressed toward the back side of the saddle, and the saddle base 1 is biased in the direction opposite to the state shown in FIG. The terminal portion 9 is the locking portion 14
are pressed into contact with each other and are securely held within the holding portion 10.

Furthermore, if the holding portion 10 is formed in advance so that the mounting hole 13 is straight when the saddle base 1 is in the above-mentioned curved state, the terminal portion 9 of the spring member 8 can be inserted smoothly, and
When the saddle base 1 is returned to its normal state from the curved state, the middle part of the mounting hole 13 is deformed to protrude toward the surface of the saddle, as shown in FIG. 4, and the terminal part 9 and the holding part 10 are This prevents the end portion 9 from wobbling and stably holds the holding portion 10.
can be held. Furthermore, as shown in FIG. 5, by providing a curved surface 15 corresponding to the outer peripheral surface of the coil spring 8 on the side surface of the locking part 14, the terminal part 9 can be more stably held within the holding part 10. Can be done.

In addition, in the above embodiment, an example was explained in which the plate-shaped locking part 14 was provided protruding from the back surface of the saddle base 1, but a structure in which a plurality of columnar projections were provided protrudingly in place of the above-mentioned locking part 14 may also be used. . In addition, the above-mentioned holding part 1
It is also possible to have a structure in which the opening of the mounting hole 13 formed at 0 is continuous with a part of the top plate 10 or the like. Furthermore, instead of the seat part 7 that holds the tip of the boat line 6, a mounting structure consisting of the holding part 10 and the locking part 14 may be adopted.

Further, in the above embodiment, the locking portions 14 are provided on the outer sides of both the holding portions 10, 10, and the end portions 9 of the coil springs 8 are symmetrically inserted into the mounting holes 13 of the holding portions 10 from the outer sides. Although configured to be inserted, the terminal portion 9 may be inserted in either the left or right direction of the holding portion 10.

Further, the structure of the present invention can also be adopted in a sports type bicycle saddle in which a spring member is integrally connected to the rear end portion of the boat line 6.

(Effects of the invention) As explained above, the present invention allows the boat line and the spring member to be connected together, without using any special tools, etc., and by utilizing the elasticity of the saddle base. Can be installed. Moreover, when the spring member is installed, the rear end of the spring member end comes into contact with the locking part, and this end is stably held within the holding part formed on the back surface of the saddle base, so that the end part does not come off. Another advantage is that rattling of the spring member can be effectively prevented.
