To this end, the present invention comprises a leaf spring which is placed such that both ends thereof come in close contact with the inner surface of a saddle panel and the center portion thereof is spaced apart from the inner surface of the saddle panel, wherein the inner surface of the center portion of the leaf spring comes in close contact with the rear end of a saddle rail, whereby when an impact occurs, the leaf spring is bent toward the inner side of the saddle panel to thereby absorb the impact.

Description

Bike saddle with support and cushioning

The present invention relates to a bicycle saddle, and more specifically, when the rider is seated on the saddle, while riding by pedaling, there is little buffering, while maintaining solidity, and when an instantaneous shock occurs on the tire while riding, the saddle is momentarily buffered. It is possible, of course, that this cushioning allows you to easily adjust and use the degree of cushioning according to the rider's physical condition and riding conditions by pedaling.

In general, the saddle of a bicycle is made of a panel made of thick leather or plastic or carbon that is injection-molded to form the basic frame of the saddle, and a vinyl, leather, artificial leather or carbon that covers the panel, or to realize softness therein. For this purpose, it consists of a cover on which the elastic sheet is laminated and a saddle rail that is fixed to the back surface of the panel to support and support the saddle, and the saddle rail is detachably mounted to the seat post by a seat clamp.

In addition, as for the overall shape of the saddle, a narrow saddle nose is provided in the front, and a wide saddle blade is provided in the rear of the saddle nose to support both hips of the rider on the saddle blade.

Therefore, the structure of these saddles is the length or width of each saddle nose or the angle of the saddle nose bending forward depending on the case of a road bike, mountain bike, triathlon, or racing bike, or depending on the rider's body shape or riding situation. And the width of the saddle wing is also different.

In addition, the structure of the saddle has recently been removed to prevent pain caused by compression of the prostate when riding a bicycle for a long time, and to relieve pain in the center of the perineum, especially from the physiological structure of women. A saddle in the form of a cutaway (wide spreading form while going in one direction) or a form that opens in a rectangle is provided to prevent pressure on the prostate area and prevents blood flow to the prostate area from dropping even when riding for a long time. For this reason, the saddle rail also uses a rail type that is bent in a form where the wire is spaced apart at a certain distance along the removed part of the saddle.

Therefore, according to this structure, the pressure on the prostate of the rider has been relieved to some extent, but the pain on both sides of the buttocks, which is the most complaining of saddle pain to riders, has not been solved.

Therefore, a coil spring was mounted on the lower wing of the saddle, that is, the back side of the panel, so that the hips supported by the wing of the saddle could be cushioned according to the shock generated during riding.

However, the pain on both sides of the buttocks is not only such an impact, but also the pain that occurs because the flow of blood purification due to the pressure generated when riding a bicycle for a long time on the buttocks in close contact with the saddle wing is not smooth.

Therefore, these coil springs exhibit some cushioning effect in a short riding time, but when riding for a long time, it may cause more severe pain due to the adverse effect of concentrating the contact between the seat bone and a specific part of the saddle wing. .

In addition, this coil spring is in the form of a coil, and the shape of the buffer is repeated in the form of a wave, which is pointed out as a complaint for riders who require instant acceleration or instantaneous acceleration when stopping, especially for triathlon or racing.

In addition, such a coil spring has a problem that it cannot satisfy the buffering and maintenance of the acceleration state by repeated fluctuations in the momentary strong buffering, and it is also impossible to arbitrarily adjust the degree of buffering.

In other words, since the coil spring repeats contraction and expansion as much as each coiled gap, the saddle that supports most of the rider's weight is swung up and down during an instant shock, causing the rider's center of gravity to be shaken, causing the saddle to bobbing. It is also the cause of the acceleration decrease due to the phenomenon.

Therefore, recently, while the saddle rail bent with wire is mounted on the back side of the saddle panel, the saddle rail is directly attached to the seat post using a seat clamp. However, the disadvantage of this is that when an impact occurs, the impact remains unchanged. Is passed on.

Therefore, in recent years, as an elastic guiding means, a wire bent in a ⊃ shape is additionally used by connecting it to the saddle rail. However, the elastic guiding means uses a certain thickness to support the rider's weight, etc. Not only the effect is halved, but also the saddle and the seatpost are separated too much by these elastic guide means, and the possibility of unnecessary flow and assembly due to the number of connecting parts (saddle rail and elastic guide means, elastic guide means and seat post) In addition to the discomfort of the body, there is a problem that impairs the aesthetics, and the height between the seatpost and the saddle is unnecessarily increased, which can cause safety problems.

Therefore, the present invention is to solve the conventional problem by supporting the saddle to be supported without shaking up and down with a certain strength during maneuvering, and reacting to the shock when the shock is transmitted, only instantaneous buffering is possible, but the buffering is not repeated.

In addition, it is intended to be able to easily adjust the degree of buffering according to the rider's physical condition or pedaling condition.

To this end, the present invention is in a state in which both ends of the leaf spring are in close contact with the rear surface of the saddle panel and the center portion is located apart from each other, and the rear end of the saddle rail is in close contact with the rear end of the saddle rail. It is possible to buffer by bending inward.

In addition, as both ends of the leaf spring are in close contact with the rear surface of the saddle panel, an inner inlet by an outer wall is provided so that the central portion is separated from each other, and both ends of the leaf spring are in close contact with the inner wall forming the inner inlet, so that the central portion of the leaf spring is in close contact with the saddle panel. I made it apart.

In addition, when the inner inlet is formed by the outer wall, both ends of the leaf spring are made of paper or transverse according to the shape of the rear end of the saddle rail, and the plate spring is inserted into the inner wall of the inner inlet so that it does not escape from the inner inlet during buffering action. The rear end of the saddle rail is provided with an opening in the inner inlet so that the rear end of the saddle rail can be raised and lowered while having a support surface or a support groove.

In addition, a cover is wrapped around the rear end of the saddle rail, which is in close contact with the back surface of the leaf spring inserted into the inner inlet, and fixed.

In addition, a filler made of a bufferable material is inserted into the inner inlet to block unnecessary buffering of the leaf spring and to prevent separation.

Therefore, in the present invention, the rear end of the saddle rail, which is fixed to the seat post, is supported at the lower end of the saddle rail fixed to the seat post. When an impact occurs on the wheel, it is transmitted to the saddle rail and transmitted to the saddle rail. The leaf spring adhered to the rear end of the car is bent toward the saddle panel and buffered, causing the rider to feel the shock to a minimum, and due to the nature of the leaf spring, the cushioning is not repeated, There is no rocking, so you can keep the momentary acceleration possible.

In addition, such cushioning is possible to arbitrarily adjust the desired buffering force by varying the thickness or the number of stacked leaf springs according to the maneuvering condition or the weight condition of the rider.

In addition, by filling the inner inlet where the central part of the leaf spring is spaced apart, it is possible to improve the fixing power of the leaf spring while removing the fine buffer of the leaf spring.

The best form for the implementation of the present invention is positioned so that both ends of the leaf spring 40 are in close contact with the rear surface of the saddle panel 10 on which the rider sits, and the center of the leaf spring 40 is spaced apart from the rear surface of the saddle panel. The rear end of the saddle rail 20 is located in close contact with the rear surface of the center of the separated leaf spring, and the rear end of the saddle rail 20 is in close contact with the rear surface of the center of the leaf spring when an impact occurs. It is a bicycle saddle with support and cushioning that is fixed so that it is not separated from the road.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

1 to 11, in the configuration of the present invention, both ends of the leaf spring 40 are located in close contact with the rear surface of the saddle panel 10 on which the rider sits, and the center of the leaf spring 40 is a saddle. It is spaced apart from the rear surface of the panel, and the rear end of the saddle rail 20 is located in close contact with the rear surface of the center of the separated leaf spring, and the rear end of the saddle rail 20 is fixed to the rear surface of the center of the leaf spring. For this, a fixing means is used.

That is, in the coupling structure of the present invention, only both ends of the plate spring 40 are in close contact with the rear surface of the saddle panel 10, and the central portion thereof is spaced apart from the rear surface of the saddle panel, and the central portion of the plate spring 40 On the back side, the rear end 21 of the saddle rail 20 is fixed in close contact.

At this time, various means for fixing can be used.

Therefore, in a state in which both ends of the leaf spring are in close contact with the rear surface of the saddle panel 10, only the central portion thereof is separated from the rear surface of the saddle panel 10, and the rear end of the saddle rail 20 is located on the rear surface of the central portion of the leaf spring. Since it is fixed in close contact, when an impact occurs on the wheel while riding, the rear end 21 of the saddle rail 20 pushes up only the central part of the leaf spring 40 to the inside of the saddle panel 10. The saddle panel can be cushioned by the bending of.

At this time, it is preferable that the front end 22 of the saddle rail 20 is fixed so that flow does not occur with the front end of the saddle panel 10, and this fixing is performed by the leaf spring 40 according to the rider's physical condition or riding condition. It is good that the saddle rail 20 is fixed so that it can be easily detached for adjusting the elastic force.

In addition, in order to be spaced apart from the rear surface of the saddle panel 10, the central portion of the leaf spring 40 is, in one embodiment of the present invention, the rear surface of the saddle panel 10, and the leaf spring 40 conforms to the shape of the saddle rail. Therefore, it is to be provided with an inner inlet 31 that can be inserted in a length form selectively in the form of paper or horizontally so as not to be separated.

10 and 11 show that the rear end of the saddle rail is vertical so that the leaf spring is mounted to be horizontally positioned to cross it, and Figs. 1, 2 and 5, 6 show that the rear end of the saddle rail is transverse to cross it. It shows a state mounted to be positioned.

In the present invention, the inner inlet 31 is integrally configured with the protruding outer wall 30, and the outer wall has an opening 32 so that the saddle rail 20 can be lifted while pressing the plate spring 40 when an impact occurs. It is optionally provided on both or on either side.

At this time, the inner surface 32a constituting the opening 32 may be guided while being in close contact with the rear end of the saddle rail 20 so as to be able to move up and down at the correct position.

In addition, the opening 32 should be opened with a width to accommodate the rear end of the saddle rail.

In addition, in the inner inlet 31, the plate spring is inserted in the form of paper or transverse, so that the inner wall of the inner inlet portion has a constant width so that the plate spring is not separated from the inner wall of the plate spring. Is to do.

At this time, the support surface 33 is configured in the form of a support groove 33a so that the three sides of both ends of the leaf spring 40 are inserted so that they do not flow. Even in the case of action, the leaf spring 40 can be made to block the flow of the left and right.

At this time, it is possible to more flexibly induce the bending of the leaf spring 40 by configuring the boundary portion where the support surface 33 or the support groove extends to the inner inlet portion as a curved surface 34, thereby further reducing the occurrence of friction noise. It will be possible.

In addition, in this state, the plate spring 40 is supported by being supported from the bottom to the top by the rear end of the saddle rail 20, and is also supported by the supporting surface or the supporting groove (33a) to prevent separation from both sides as well as below. However, in order to induce the aesthetic appearance or close contact between the saddle rail and the leaf spring, the cover 50 is provided to prevent separation of the leaf spring in case of repetitive impact or the occurrence of the leaf spring.

At this time, the cover is coupled so that it is in close contact with the rear end of the saddle rail, which is in close contact with the rear surface of the central part of the leaf spring, so that unnecessary flow can be blocked during buffering.

In addition, as shown in Figs. 6 to 8, when the cover is not deeply inserted into the support surface or the support groove provided on the inner wall of the inner inlet, for example, the shape of the saddle panel is sharpened. In this case, when the outer wall is configured to protrude from the rear surface of the saddle panel to form the inner inlet, if the protrusion is formed low, the rear end of the saddle rail in close contact with the rear surface of the central part of the leaf spring is formed by the outer wall. In the case of protruding upward even in the state of being inserted into the part, it can be solved by protruding and fixing the inner recess 51 so that the rear end of the saddle rail can be inserted into the cover.

In addition, in the case of configuring the inner inlet 31 in the present invention, the inner inlet is not separately formed on the inner wall of the inner inlet, but the inner inlet is inclined downward and the plate spring is positioned at the top. When the rear end 21 of the saddle rail is placed on the rear side of the central part and then fixed with a cover, the leaf spring can be more easily bent.

In this case, if the filling material 60 is filled in the inner inlet so that the leaf spring can be fixed more firmly, the flow of the leaf spring is prevented, and the buffering force is not generated even when a small impact is transmitted, and another supplementable buffer The function can be implemented and unexpected flow of the leaf spring can be prevented.

Of course, such a filling material can be applied even in a state where a support surface or a support groove is provided on the inner wall of the inner inlet.

The filler in the present invention is a rubber material or silicone capable of buffering while having a filling function, if possible, and of course, various materials can be selected and used for the same function and use.

In the present invention, the outer wall is formed to implement the inner inlet, but as shown in Fig. 8, the outer wall is provided with a support surface or a pair of protrusions 30a having a support groove in a shape facing each other, and a distance corresponding to the length of the plate spring In this case, the same effect can be generated even when the cover is provided with an outer wall, and in this case, when the cover is combined with the opening 51 provided, as well as preventing the plate spring from separating, the saddle rail can be raised and lowered. Of course, the object of the present invention can be sufficiently achieved.
