## Background
CROSS REFERENCE
The present application is a continuation-in-part, application of U.S. patent application Ser. No. 11/307,240, filed on Jan. 27, 2006, now abandoned, of which the entire disclosure is incorporated herein.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a bicycle saddle.
2. Description of the Related Art
Modern bicycle saddles preferably include a padding comprised of a first resilient section and a second resilient section, with the first resilient section being softer than the second resilient section such that the first resilient section provides more cushioning effect than the second resilient section. Furthermore, the first resilient section primarily supports the external genital of a rider and thereby reducing the pressure placed on the perineum. Examples of such bicycle saddles are disclosed in U.S. Pat. No. 5,165,752 to Terry, U.S. Pat. No. 5,387,024 to Bigolin and U.S. Pat. No. 6,149,230 to Bontrager.
However, a problem with these modem saddle designs is the expandability of the first pad is limited by the fact that the second resilient section completely surrounds the edge of the first resilient section. Furthermore, each of Terry, Bigolin and Bontrager discloses a seat cover applied over the padding. The seat cover can also limit the expandability of the first pad, thereby reducing the buffering effect of the first resilient section.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
SUMMARY OF THE INVENTION
A bicycle saddle includes a frame and a padding placed over the frame. The padding includes a leading edge, a trailing edge and a recessed supporting surface defined therein for receiving an elastic element. The elastic element includes leading and trailing edge portions for receiving the leading and trailing edges of the padding respectively. The elastic element further includes two side edges extending longitudinally between the leading and trailing edge portions exposed from the recessed supporting surface so that when the bicycle saddle is subject to a force of weight transmitted from a rider, the elastic element can extend transversely to the longitudinal direction between leading and trailing edge portions thereof without confinement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 through 3 in conjunction with FIG. 5, a bicycle saddle 10 in accordance with a first embodiment of the present invention is substantially wedge-shaped and includes a narrow front portion 14 and a flared rear portion 15. The narrow front portion 14 becomes progressively narrower towards its front end. The bicycle saddle 10 is comprised of a frame 11, a padding 12, an elastic element 20 and a suspension rail 16.
The frame 11 is also substantially wedge-shaped and has substantially the same dimension as the bicycle saddle 10.
The padding 12 is made of a resilient material and is placed over the frame 11 so as to define a sitting surface having a leading edge and a trailing edge, a height and a recessed support surface 17 disposed intermediate the leading and trailing edges. The recessed support surface 17 includes a height lower than that of the sitting surface and is adapted to receive the elastic element 20. The elastic element 20 is slidably installed on the recessed support surface 17.
The elastic element 20 has a depth and is made of a resilient material that is softer than the padding 12 so as to provide more cushioning effect. The elastic element 20 has a first surface 21 providing a part of the sitting surface that the rider sits on. The elastic element 20 further includes a second surface 22 adapted to be securely received by the recessed support surface 17. In addition, the elastic element 20 includes a leading edge portion 23, a trailing edge portion 24 and two side edges 25 extending longitudinally therebetween. The leading and trailing edge portions 23, 24 conform to the extreme forward end and extreme rear end of the recessed support surface 17, respectively, and the side edges 25 are exposed from the recessed supporting surface 17.
As best seen from FIGS. 4 and 6, if the rider sits on the bicycle saddle 10, the elastic element 20 will be in a sagged condition, and, its side edges 25 will extend transversely (in a direction as indicated by arrows) to the overall longitudinal direction of the bicycle saddle 10 and therefore extends beyond the side portions of the outermost perimeter of the recessed support surface 17.
FIGS. 7 and 8 show a second embodiment of the bicycle saddle 10′ of the present invention, wherein like numerals are designated to denote like components of the first embodiment, but bearing a prime. The bicycle saddle 10′ is differentiated from the first embodiment in that the elastic element 20′ includes air 28′ filled therein. The elastic element 20′ further includes an air inlet mouth 26′ adapted to receive a valve 27′. The valve 27′ is connectable to a pumping apparatus (not shown), with the pumping apparatus capable of charging the air 28′ into the elastic element 20′ and discharging the air 28′ outwardly of the elastic element 20′.
FIG. 9 shows when a plurality of evenly distributed forces (designated as F) are applied to the elastic element 20′, the elastic element 20′ will get sagged and extend transversely outwards beyond the outermost perimeter of the recessed support surface 17′.
FIGS. 10 to 12 show a third embodiment of the bicycle saddle 10′′ of the present invention, wherein like numerals are designated to denote like components of the first embodiment, but bearing a double prime. The bicycle saddle 10′′ is comprised of a frame 11′′ and an elastic element 20′′. The frame 11′′includes a front pad 111′′, two rear pads 112′′ and a connective portion 113′′ for connecting the front pad 111′′ to the two rear pads 112′′. A space 114′′ is defined between the front pad 111′′ and the two rear pads 112′′ above the connective portion 113′′. A space 115′′ is defined between the rear pads 112′′.
The length L of the two rear pads 112′′ is no larger than 120 mm. In the preferred embodiment, the length L of the two rear pads 112′′ is 120 mm. The width T of the connective portion 113′′ is no larger than 50 mm. In the preferred embodiment, the width T of the connective portion 113′′ is 40 mm. The depth of the space 114′′, i.e., the distance from a plane defined by the pads 111′′ and 112′′ to the top of the connective portion 113′′, is marked with “H.” The depth H of the space 114′′ is no larger than 30 mm. In the preferred embodiment the depth H of the space 114′′ is 30 mm.
The elastic element 20′′ is installed on the connective portion 113′′ in the space 114′′. The elastic element 20′′ can support external genitals of a rider without excessively pressing the same. The elastic element 20′′ is softer than the front pad 111′′ and the two rear pads 112′′ of the frame 11′′. The elastic element 20′′ can be attached to the frame 11′′ by adhesion, gluing, injection molding or in any other proper manner. The elastic element 20′′ includes two portions 201′′ extending beside the outer side of the perimeter of the front pad 111′′ and a front concave edge 204′′ for receiving the front pad 1ll′′. The elastic element 20′′ further includes two portions 202′′ extending beside the outer side of the perimeter of the two rear pads 112′′ and two rear concave edges 205′′ for receiving the two rear pads 112′′ respectively. In addition, the elastic element 20′′ includes an extensive portion 203′′ between the rear concave edges 205′′. The extensive portion 203′′ of the elastic element 20′′ is located between the two rear pads 112′′ within the space 115′′. Thus, the bicycle saddle 10′′ is aesthetically pleasant, and the connection of the elastic element 20′′ to the frame 11′′ is firm. The extensive portion 203′′ of the elastic element 20′′ can adequately support riders without excessively pressing them.
The width t of the elastic element 20′′ is identical to the width T of the connective portion 113′′. The thickness h of the elastic element 20′′ is marginally smaller than the depth H of the space 114′′.
FIGS. 13 and 14 show a rider bearing on the bicycle saddle 10′′. The rider's hips are supported on the two rear pads 112′′. The length L of the two rear pads 112′′ is no larger than 120 mm so that the rider's hips can be well supported and that the rider can feel comfortable.
While the rider is pedaling with legs, the rider's thighs are located beside the connective portion 113′′ and the elastic element 20′′. The width T of the connective portion 113′′ is identical to the width t of the elastic element 20′′ that is no larger than 50 mm so that the rider's thighs will not rub against the connective portion 113′′ and the elastic element 20′′. The slim profile of the saddle makes the saddle look advanced, modem and appealing to customers.
Moreover, the rider's external genitals are located on the elastic element 20′′ that is softer than the pads 111′′ and 112′′ of the frame 11′′. Hence, the external genitals can be supported without being excessively pressed so that the external genitals will not be hurt because of fierce vibration. The thickness h of the elastic element 20′′ is marginally smaller than the depth H of the space 114′′. However, the elastic element 20′′ is thick enough to buffer the external genitals.
Thus, in view of forgoing, it is therefore an advantage of the present invention to provide a bicycle saddle 10, 10′, 10′′ which comfortably supports the external genitals of a rider
It is another advantage of the present invention to provide a bicycle saddle that provides good aeration to the rider.
It is yet another advantage of the present invention to provide an elastic element 20, 20′ adapted to extend beyond the outermost perimeter of the recessed support surface 17, 17′ and thereby avoid inducing discomfort to the rider.
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of invention and the scope of invention is only limited by the scope of accompanying claims.
