## Title
Adjustable flex saddle for a bicycle or a motorcycle

## Abstract

A saddle on which an individual is seated while riding a bicycle or a motorcycle. The saddle includes a flexible base to support the rider's weight and a stationary nose cap attached to the flexible base. One end of a bumper retaining block is pivotally and detachably connected to the nose cap. A resilient bumper is located between the flexible base and the bumper retaining block. A pair of rails which runs along the bottom of the flexible base is attached to the bicycle/motorcycle. The pair of rails is coupled to the bumper retaining block to push the block towards the flexible base with the resilient bumper sandwiched therebetween. The bumper retaining block can be detached from the stationary nose cap so that the resilient bumper can be replaced by a bumper having a different density to selectively control the flexibility of the base.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is related to Provisional Patent Application No. 61/950,952 filed Mar. 11, 2014.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an adjustable flex saddle to support the weight of one riding a bicycle or a motorcycle. The saddle has a replaceable resilient bumper that is sandwiched between a bumper retaining block and a flexible saddle base to selectively control the stiffness of the saddle.
2. Background Art
A saddle is a well known component of a bicycle or a motorcycle on which a rider is seated. However, the weight to be supported by the saddle can change dramatically depending upon the rider. That is to say, the stiffness of the conventional saddle experienced by the rider is the same regardless of the rider's weight. Moreover, different riding conditions (e.g., smooth roadways or mountainous terrain) may necessitate that the stiffness of the saddle be adjusted to suit the experience and comfort of the rider. Therefore, what would be desirable is a means carried by the saddle to enable a rider to be able to selectively and continuously adjust the stiffness of his saddle to take into account his weight, riding conditions and comfort. In this same regard, being able to adjust the stiffness of the saddle would be advantageous to accommodate the weights of different riders when the bicycle/motorcycle is shared or if the saddle is transferred from one bicycle/motorcycle to another.
SUMMARY OF THE INVENTION
In general terms, an adjustable flex saddle is disclosed to be used by one riding a bicycle or a motorcycle. The adjustable flex saddle includes a flexible saddle base upon which the rider's weight is supported. Extending across the bottom of the saddle base between the front and the rear thereof is a pair of detachable saddle rails. The rails are connected to a clamp by which the adjustable flex saddle is correspondingly connected to the bicycle or motorcycle. Affixed to the front of the saddle base is a stationary end cap. Located adjacent the end cap at the front of the saddle base is a bumper retaining block. A first end of the bumper retaining block has an open mouth and the opposite end has a coupling tail which is pivotally and detachably connected to the stationary end cap by means of a pivot pin so that the bumper retaining block is rotatable relative to the end cap. First ends of the pair of saddle rails are joined together to form a round nose which is removably received in the open mouth at the first end of the bumper retaining block. The opposite free ends of the pair of saddle rails are removably received by holes formed in respective rail holders which project from the rear of the flexible base.
A replaceable elastomeric bumper that is preferably manufactured from a resilient (e.g., rubber) material is located between the flexible saddle base and the bumper retaining block. When the round nose of the saddle rails is removably received by the open mouth of the bumper retaining block, the bumper retaining block is held over and pushed towards the replaceable bumper by which the bumper is compressed against the saddle base. The density (i.e., hardness) of the bumper controls the flexibility of the base and the stiffness of the saddle. When it is desirable to change the flexibility of the saddle base to suit the needs of the rider, the pivot pin is first removed so that the bumper retaining block can be disconnected from the stationary end cap to permit the pair of saddle rails to be detached from their connection between the bumper retaining block and the rail holders. The replaceable bumper can then be removed from the adjustable flex saddle and replaced by a different bumper having a different density by which to enable the rider to selectively adjust the flexibility of the flexible base and the stiffness of the saddle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring concurrently to FIGS. 1-6 of the drawings, there is shown a preferred embodiment for an adjustable flex saddle 1 of the kind on which an individual is seated while riding a bicycle. Although the saddle 1 referred to above is ideally used by one riding a bicycle, the advantages of this invention are also applicable to saddles used by those riding motorcycles. As will be explained in greater detail hereinafter, one seated on the saddle, whether it is used on a bicycle or a motorcycle, will be able to selectively adjust the stiffness of the saddle to suit his particular riding requirements.
Located at the top of the adjustable flex saddle 1 is a seat 3 upon which the rider's pelvis is supported. The saddle seat 3 (best shown in FIGS. 5 and 6) is typically manufactured from a comfortable cushion (e.g., foam) material. The saddle seat 3 is often surrounded by an outer protective and decorative cover 5 that is manufactured from leather, or the like. Lying underneath the seat 3 of the adjustable flex saddle 1 is a base 7. The saddle base 7 is typically manufactured from a relatively stiff but flexible (e.g., nylon or carbon fiber) material. The saddle seat 3 and the saddle base 7 are attached to and lie one above the other.
A pair of elongated detachable rails 9 and 10 run longitudinally along the bottom of the saddle base 7 from one end thereof to the other. The saddle rails 9 and 10 are preferably manufactured from a flexible metallic material having a spring memory. First ends of the rails 9 and 10 are co-extensively (i.e., continuously) joined to one another to form a round nose 12. The opposite free ends of the rails 9 and 10 are removably received by respective (e.g., molded) rail holders 14 and 16 which are spaced from one another and project from the rear of the saddle base 7. Each of the rail holders 14 and 16 has a hole 18 and 20 formed therein (best shown in FIG. 4) within which to slidably and removably receive the free end of a corresponding one of the saddle rails 9 and 10. The saddle rails 9 and 10 are connected to the bicycle by means of a conventional seat clamp (designated 50 and shown in phantom lines in FIG. 2).
As an important detail of the adjustable flex saddle 1, a bumper retaining block 24 (best shown in FIGS. 4-6) lies adjacent and is coupled to a stationary U-shaped end cap 26 that is affixed to the front of the saddle base 7. The bumper retaining block 24 has an open mouth 28 (best shown in FIG. 4) located at one end thereof and an outwardly-extending coupling tail 30 at the opposite end. The U-shaped end cap 26 has a cavity 32 formed therein within which to receive the coupling tail 30 of the bumper retaining block 24 such that the end cap 26 surrounds coupling tail 30. A removable coupler (e.g., a pivot pin 34, or the like) extends through each of the end cap 26 and the coupling tail 30 which is surrounded by the end cap. Thus, the coupling tail 30 of the bumper retaining block 24 is pivotally and detachably connected to the stationary end cap 26 to enable block 24 to rotate relative to the end cap 26 towards and away from the saddle base 7 (best shown in FIG. 6).
As another important detail of this invention, a replaceable elastomeric bumper 36 is located below the rotatable bumper retaining block 24 at the front of the saddle base 7. The bumper 36 is preferably manufactured from a resilient (e.g., rubber) material having a spring memory and an ideal thickness of about 5-6 mm.
A bumper recess 38 (best shown in FIG. 4) is formed (e.g., molded) at the front of the saddle base 7 so as to lie above the bumper retaining block 24 and establish a seat within which the replaceable bumper 36 is received. After the bumper 36 is located within the bumper recess 38, the round nose 12 of the saddle rails 9 and 10 is moved into the mouth 28 of the bumper retaining block 24. The bumper retaining block 24 is then pivotally and detachably connected to the end cap 26 by means of the removable pivot pin 34, such that the block 24 is held over and against the bumper 36. By virtue of the bumper retaining block 24 rotating around the pivot pin 34, the resilient bumper 36 will be compressed against the saddle base 7, such that impact forces generated during a ride will be better absorbed by the saddle base which communicates with the block 24 by way of the saddle rails 9 and 10.
In this same regard, the bumper 36 can be removed from the bumper recess 38 and replaced by another bumper from a group of elastomeric bumpers manufactured from resilient materials having different densities. That is, should the rider wish to reduce the flexibility of the saddle base 7 of the adjustable flex bicycle saddle 1, he can select a denser and harder bumper from the group of resilient bumpers to be seated within the bumper recess 38 above the bumper retaining block 24 at the front of the base 7. In cases where the rider wishes to increase the flexibility of the saddle base 7 of the saddle 1, he can select a different bumper having a reduced density in order to customize the stiffness of the saddle to suit his riding needs.
FIGS. 5 and 6 of the drawings show the adjustable flex bicycle saddle 1 after a replaceable bumper 36 that meets the needs of the rider has been selected and seated in the bumper recess 38 at the front of the saddle base 7. The free ends of the detachable rails 9 and 10 are pushed inwardly of the holes 18 and 20 formed in the rail holders 14 and 16 at the rear of the saddle base 7. The round nose 12 at which the rails 9 and 10 are joined together and which lies opposite the free ends is removably received inwardly of the open mouth 28 of the bumper retaining block 24. With the bumper retaining block 24 pivotally and detachably connected to the stationary end cap 26, the pair of detachable rails 9 and 10 will be suspended between the rail holders 14 and 16 and the bumper retaining block 24 at opposite ends of the saddle base 7. The round nose 12 of rails 9 and 10 pushes the bumper retaining block 24 towards the replaceable bumper 36 to be compressed against the saddle base 7.
Should a new rider be seated on the adjustable flex saddle 1 or the conditions of the riding path change, it may be desirable to change the flexibility of the saddle base 7 by replacing the bumper 36 that is currently being held against the saddle base. To accomplish the foregoing, and referring particularly to FIGS. 4-6 of the drawings, the pivot pin 34 is first removed, and the bumper retaining block 24, with the round nose 12 of the rails 9 and 10 still coupled thereto, is withdrawn from the stationary end cap 26. The detachable rails 9 and 10 are then pulled out of their prior attachment between the rail holders 14 and 16 and the bumper retaining block 24.
The rider may now simply remove the original resilient bumper 36 from its bumper recess 38 and replace the original bumper with a different bumper having the density required to change the flexibility of the saddle base 7 and the stiffness of the saddle 1 to respond to the weight of the rider. After the new bumper is in place, the rotatable bumper retaining block 24 is once again pivotally and detachably coupled to the stationary end cap 26 so as to be held down against the saddle base 7 with the new bumper sandwiched therebetween. The same or a different pair of rails 9 and 10 can be detachably connected between the retaining block 24 and the rail holders 14 and 16 in the manner previously explained.
