Abstract:
This relates to a bicycle saddle of the type that presents two identical portions ( 1, 1 ′) longitudinally symmetrical. Thanks to its special conformation, said saddle permits the cyclist to avoid the occurrence of pathologies normally caused by the use of a racing saddle of commonly known types, eliminating the crushing of the vascular structure of the perineum, as well as the testicles of male cyclists and the clitoris of female cyclists. The special geometry permits a pedaling action without causing friction of the thigh muscles, in particular the delicate and adducent muscles.

   BACKGROUND OF THE INVENTION 
   The present invention relates to a bicycle saddle. In particular, the saddle according to the invention is the result of an improvement of the saddle described in my earlier U.S. Pat. No. 7,537,281, granted May 26, 2009. 
   In order to understand the characteristics of the bicycle saddle according to the invention, and the structural ergonomic difference that distinguishes it from all other bicycle saddles available on the market today, the innovation should be presented in a context of medical science, which in the world of professional athletes, constitutes an important work instrument necessary to obtain better performance. 
   In order to demonstrate specifically what problems bicycle saddles currently available on the market can provoke for cyclists who use bicycles for long or short road distances, scientific research has been carried out in the field of Urology. 
   Many urologists in certain universities in both the United States and in Europe carried out research studies between 1986 and 2002, on the effect of the temporary, and in many cases, even the permanent lack of sensitivity in the penis, that occurs as a result of the vascular compression of the perineal structures when the cyclist is seated on the bicycle saddles that are still on the market; the data obtained from this research have been used by urologists who have deducted that the long narrow tip of the saddle is the aspect which causes the aforesaid health problems. 
   For a correct definition, we will provide summary of two scientific research surveys conducted by the most famous urologists. The first, the American urologist Irwin Goldstein, who in the research survey he conducted in 1996, already suggested that there existed a danger of impotence for men who rode bicycles. Goldstein sustained that the problem lay in the saddle; this because of the form of the saddle with the narrow hard tip which caused a pressing of the perineum (Article published in the magazine Panorama dated 29 Nov. 2001) and scientific study conducted with Nehra A., Goldstein I., Pabby A., Nugent M., Huang Y H., de las Morenas A., Krane R J., Udelson D., Saenz de Tejada I., Moreland R B. Mechanism of venous leakage: a prospective clinicopathological correlation of corporeal function and structure. J. Urol. 1996 October; 156(4)1320-9). 
   The second urologist, Ulrich Schwarzer of THE DEPARTMENT OF UROLOGY, UNIVERSITY MEDICAL CENTRE OF COLOGNE, 50924 GERMANY, conducted with Frank Sommer, Theodor Klotz, Claus Cremer, Udo Englemann, first in 1999, then again in 2002. 
   The conclusions of this study states the following: 
   It was possible to demonstrate that the most important factor for protecting the blood flow of the penis, does not depend on the amount of padding, but on the length of the saddle, which can prevent the compression of the structures of the pelvic floor, and the compression of the deep artery and vein of the penis on the pubic arch.

   SUMMARY OF THE INVENTION 
   The aforesaid documents concerning bicycle saddles, and in particular, racing bicycles saddles, do not satisfy the indications of the urological medical research for the protection of the blood flow of the penis, and furthermore, only a part of these saddles present a geometry which is compatible with the needs of the cyclist, and especially with those of professional athletes. 
   According to the data acquired above, it is obvious that a bicycle saddle must have a central channel of a suitable width in order to avoid the compression of the vascular structures of the perineum: and therefore in order to obtain this, the saddle shall be constructed in a manner so that the cyclist is supported on its structure exclusively on his gluteus muscles, the ischiatic tuberosities, and the ischial pubic rami and the saddle on its sides must have a geometry that during the pedalling action, prevents friction against the gracilis and adducent muscles. 
   The saddle according to the invention presents a seat that is uniformly distributed on the gluteus muscles, the ischiatic tuberosity, and the pubic ischium while maintaining the perineal plane free; the eagle beak tip also permits the external genitals to be free of compression. The rear width most preferred by cyclists is approximately 130-140 mm narrowing inwards to a front width of approximately 40-45 mm where the structures then slope downwards on a non-limiting angle of 30°-45° for racing bicycle saddle, and a non limiting angle of 75° for touring bicycle saddle. The geometry of the saddle according to the finding follows the shape of the thigh muscles, thus avoiding friction of the gracilis and adducent muscles that could lead to irritating problems in the lower limbs during pedalling action. In fact, it is a typical habit of professional cyclists to pedal with their knees averagely directed towards the bicycle frame in order to increase their strength and sports performance.

   DETAILED DESCRIPTION OF THE INVENTION 
   The saddle according to the invention is designed for use on racing bicycles, with non-limiting length of 27 cm, and rear width of approximately 13-14 cm, on a touring bicycle, with non-limiting length of 20 cm, and rear width of approximately 18-22 cm. 
   As can be seen in  FIG. 1  where the saddle is seen in perspective from above, the saddle presents two identical portions  1 ,  1 ′, longitudinally symmetrical, with a long central channel  20  at the front part of its median zone. Each of these identical portions presents a rear part  2 ,  2 ′, that conjointly for the racing bicycles have a non-limiting width of 13-14 cm, and a non limiting width of 18-22 cm for touring bicycles. The two parts  2 ,  2 ′ are reciprocally united by a hollow-shaped section  21 . As can be seen in particular in  FIG. 2 , their rear portion is sloped in an upward direction on an angle of approximately between 10 and 20 degrees. 
   The parts in closest proximity to the central hollow  21  of parts  2  and  2 ′ shown in the figure with reference numerals  2 ″ and  2 ′″, are substantially flat and have an overall dimension of approximately 7 cm, after which they slope downwards in relation to the vertical plane on an angle that varies between approximately 45° and 60°, terminating with the side parts  2 ″″ and  2 ′″″. 
   In the following anatomical figures, it will be made clear that the flat parts  2 ″,  2 ′″ serve to support the gluteus muscles and the ischiatic tuberosities, and vice versa on the sloped parts  2 ″″,  2 ′″″, only the gluteus muscles are supported, as can be seen in  FIG. 11 . 
   As can be seen in  FIG. 1 , but also in  FIG. 3 , at their rear intermediate zone, parts  2 ,  2 ′ are configured to resemble a recess  3 , that substantially presents a dovetail shape whose ends  5 ′,  5 ″ are at a reciprocal but non-limiting distance from each other of approximately 2.5-3 cm, terminating with a front end  5  in a semi-circular shape. In fact, the hollow  21  begins from point  5 , and as seen previously, said hollow serve as a connecting element for the two parts  2 ,  2 ′. Such hollow has a variable length between approximately 4-6 cm and a depth of approximately 1.5 cm. Its presence is fundamental in order to prevents the coccyx from touching the saddle surface, and especially in cases where the road surface is particularly uneven. 
   The fact that the coccyx does not come into contact with the saddle surface prevents micro-traumas that could occur, provoking considerable pain on the vertebral column. The rear parts  2 ″,  2 ′″, are united to the front portion  7 ″,  7 ′″, by a slight slope. At this point the saddle has a total non-limiting width of 7 cm. 
   The front portions  7 ″,  7 ′″, are inclined in an upward direction at a non-limiting angle of about 5° for racing saddles and a non limiting angle of approximately 10°-20° for touring saddles, then they are destined to approach each other considerably in a reciprocal manner until they are at a reciprocal distance of approximately 4-4.5 cm from each other, at points  8 ,  8 ′. In these zones, the side of the saddle slopes in a perpendicular direction downwards, and the corners are suitably rounded to prevent any irritating contact with the skin of the thigh. 
   The ischiatic tuberosities and ischial pubic rami are positioned above these front parts of the saddle, and therefore the ischial pubic rami support the concentrated load of the human body which is distributed in a uniform manner for its complete length on the support surface, when the cyclist is seated on the saddle according to the present invention. 
   Moreover, the ischial pubic rami are supported on the front parts  7 ″,  7 ′″, at the points  8 ,  8 ′ serve to support a part of the weight of the trunk of the human body when the cyclist&#39;s hands are positioned on the bicycle handlebars. 
   Lastly at the front terminal part of the saddle  8 ,  8 ′, where the seat of the pelvis terminates, are the sections  9 ,  9 ′, sloped downwards in an eagle-beak configuration on a non-limiting angle of 30°-45° for the racing saddle and a non-limiting angle of 75° for the touring saddle, as can be seen in  FIG. 2 . At the front end of the saddle the two sections  9 ,  9 ′ unite in a substantially semi-circular form with a diameter of approximately 4-3.5 cm to maintain the two portions  1 ,  1 ′ united at the front. 
   Such a strong slope of sections  9 ,  9 ′  FIGS. 9 ,  10 , prevents any crushing of the testicles, in the case of men, and the clitoris, in the case of women, when the saddle is in use, in compliance with the above-mentioned scientific urological research surveys. 
   Moreover, this also prevents the compression of the body of the penis, the deep dorsal artery and vein, thus maintaining normal blood flow. 
   The parts  9 ,  9 ′, which on the racing bicycle saddle are sloped downwards at a non-limiting angle of 30°-45° are of considerable help to the athlete during the final sprint, or during timing races, at the moment when he moves the pelvis forwards, to provide a minimum support for the gluteus muscles, thus preventing all compression on the anus and in particular, on the prostate. 
   On observing  FIG. 3 , it can be seen that the saddle has a particularly streamlined dynamic form. This streamlined form is able to satisfy the professional athlete in particular, since he should never feel any irritation or pain when pedalling in training and during a race. With reference to the central channel  20  in particular, at its rear end it has a semi-circular form with a diameter that varies between approximately 3 and 5 cm. 
   Moving further forward, the channel  20  narrows to a width of approximately 2.5 cm terminating at the front with a zone that also has a substantially semi-circular configuration. 
   At the rear wider part of the channel, the anus, the prostate (for male cyclists naturally) can be housed comfortably, the prostate measuring approximately 2.5 cm in diameter according to the scientific tests performed; and the pudenda arteries, dorsal veins and arteries and the body of the penis and the testicles will be positioned on parts  9 ,  9 ′. Since the central channel  20  is open, female cyclists will not be subjected to any pressure on the vagina, which maintains constant air flow, an aspect which is important for the preservation of the complex interaction between the micro-organisms that compose the vaginal flora; the vestibule, the inner and outer labia and the clitoris being positioned at the sections  8 ,  8 ′. 
   Therefore channel  20  fully satisfies all the aforesaid requirements provided in the scientific urological research survey; in fact the saddle according to the invention was subjected to scientific urological testing on 29 young healthy cyclists, with a body weight between 45 and 70 kg. and aged between 18 and 30 years old, first simply seated on the saddle of the invention for a period of 15 minutes, followed by a pedalling action on said saddle for a further 15 minutes, measuring the blood flow of the perineal structures, using a Clark type electrode positioned on the gland of the cyclist&#39;s penis. 
   The data obtained and compared with the data of the latest scientific test performed by the Urologist Schwarzer demonstrate that the saddle according to the invention is statistically superior to the saddle that had given the best results in the survey, thus demonstrating the regular blood flow of the perineal vascular structures, both when seated, as well as during pedalling action. 
   In this relation, it is important to note that when using the saddle according to the invention, male cyclists felt no friction on the anus and on all of the penis skin surface, thus preventing any eventual rashes or dermatitis caused by friction. Moreover, the testicles are maintained constantly in the air flow, thus maintaining the temperature under 37°, which is the best possible temperature for normal seminal liquid production. 
   It should also be noted that in the intermediate part of the racing saddle (see  FIG. 3 ), that is, the area defined approximately and respectively by points  16 ,  16 ″ and  16 ′,  16 ′″, the saddle has a maximum width that permits the ischiatic tuberosities and the ischial pubic rami to be supported on their internal part. 
   This aspect is important, so that the attachment of the semi-tendinous muscles, the bicipital muscles of the femur, the gracili muscles, and also the perineal nerves and lower nerves of the buttock are not compressed in any way, thus maintaining regular sanguineous circulation, and consequently also the oxidation of the muscular fibres during pedalling action. 
   Further on,  FIG. 1A : exploded view of the main saddle components according to the invention of: (A) the padding that will mainly be covered in leather, (B) the supporting shell made in nylon plus a percentage of carbon or other plastic materials, and (C) support rail made of steel tubing. 
     FIG. 2 : vertical longitudinal section we can observe the particular ergonomic form that characterises the saddle according to the invention. 
   The overlying padding  11 , with a non-limiting thickness of 1-1.5 cm, in the front area, and a non-limiting thickness of 2-10 mm at the rear is made of a two-component polyurethane elastomer foam, or compact or foam polyurethane, or styrol-butylene-styrol, or vulcanized rubber foam, or some other plastic materials suitable for the needs of the saddle of the invention; each of these materials will be used in an appropriate manner in the various models that compose the range of saddles according to the invention. These materials which constitute the padding are able to support the body weight of the cyclist when he is seated on the saddle according to the invention, thus preventing the ischiatic tuberosities and ischial pubic rami from touching the underlying support shell. 
   The underlying support shell has a non-limiting thickness of approximately 2-3 mm, and is formed to perform an ergonomic function to house the gluteus muscles and a part of the ischiatic tuberosities and, in the front areas, the ischial pubic rami; due to this design and the absolute minimum of support surface, the cyclist&#39;s body weight is uniformly distributed on every square centimeter of the surface when he is seated on the saddle according to the invention, without the cyclist feeling any crushing or bruising of delicate parts of the perineal floor and the juncture of the muscles. 
   Basically, the saddle according to the invention is a small-sized saddle for a bicycle that fulfills the requirements of the amateur cyclist as well as those of the professional athlete. 
   The support rail  13  is fixed to the shell on special seats, in the front  15 , on special pockets, at the rear  16 , on supports pre-formed on the shell. In  FIG. 4 , the positioning and blocking of the rail in points  16 , is composed in plan view of two prismatic raised elements on which will be fixated with self-threading screws two plates  22 ,  22 ′ ( FIG. 5 ) previously provided with holes for the screws, and united together by means of a plate  23 , bearing the manufacturer&#39;s trademark, which can be seen in  FIG. 11 ; a strip  18 , with a width of approximately 6 mm, and approximately 3.5 mm thick, is applied around the perimeter, and on which the final part of the leather covering of the saddle according to the invention will be later glued and stapled. 
   The support rail  13 ,  FIG. 5 , is formed in a single tube in stainless steel, aluminium, or titanium, or any other materials resistant and lightweight at the same time, with the rear part closed and facing upwards for approximately 4 cm and a width of approximately 10 cm in the upper area, and formed following the shape of the underlying surface of the saddle shell according to the invention. The saddle securely attached to the rail, which is in turn fixed to the bicycle support, remains always stable during the pedalling action of the cyclist, when the body weight is placed in an alternating manner on parts  1 ,  1 ′ of the saddle according to the invention (see  FIG. 8 ). 
   Below, with the relative drawings, are the descriptions of different ergonomic forms of the shell surface of the racing saddle and the touring saddle according to the invention. 
     FIG. 6  shows the section of the racing saddle with the dissected coxal bone above it, arranged in a pedalling position of approximately 45°;  FIG. 6A  with the ischial pubic rami compressing the saddle padding with the weight of the human body; the front surface of the shell is directed in an upward direction on a non-limiting angle of only 5° to house the ischial pubic rami, which in this position, are moved in a downward direction, while the tip of the saddle moves downward at a non-limiting angle of approximately 30° or 45° to permit the professional athlete to place his gluteus muscles on it during the final sprint or during timing races; the gluteus muscles are supported on the rear part directed upwards at a non-limiting angle of 10°-20°. 
     FIG. 7  shows the section of the touring saddle with the dissected coxal bone above it, set in a pedalling position of approximately 60°;  FIG. 7A  shows the ischial pubic rami that compress the saddle padding under the weight of the human body; the front surface of the shell is directed in an upward direction on a non-limiting angle of 10°-20° to house the ischial pubic rami which in this touring position, are moved in a upward direction, while the tip is directed downwards at a non-limiting angle of approximately 75°; the gluteus muscles are supported on the rear part directed upwards at a non-limiting angle of 10°-20°. 
     FIG. 8  shows a front view of the saddle according to the invention and a dissection of the coxal bone housed above the saddle surface of parts  1 ,  1 ′; the four quadrants—upper left hand q 1 , upper right hand q 2 , lower left hand q 3 , lower right hand q 4 , all remain in a perfectly stable position in the correct axis with the saddle during any kind of pedalling action even intense or excessive, also due to the above described support rail, thus permitting all the muscles of the lower limbs and other vital functions to interact in a uniform manner. 
     FIG. 9  shows the dissection of the perineal floor structures, the ischiatic tuberosities, ischial pubic rami, gluteus muscles and genitals, their position on the surface of the saddle; inside the channel  20 , the coccyx, anus, pudenda arteries, prostate, body of the penis, deep dorsal vein and artery of the penis, penis skin, and testicles are housed without being subject to any compression, the same principle being applied to prevent compression on the vagina, inner and outer labia and the clitoris for female cyclists. 
   In this manner the blood flow of the penis is uninterrupted during the cyclist&#39;s pedalling action.

     FIG. 10  shows the perspective view of the dissection of the coxal bone positioned on the surface of the saddle according to the invention, demonstrating how the space occupied by the body of the penis and the testicles is free of any obstruction in points  8 ,  8 ′ in  FIG. 1 , and parts  9 ,  9 ′ ( FIG. 10 ), which are directed downwards in eagle beak form in these zones at a non-limiting angle of 30°-45° for the racing saddle, and a non-limiting angle of 75° for the touring saddle. 
     FIG. 11  shows the rear view of the saddle according to the invention with the dissection of the gluteus muscles, the coccyx, and the sacrum, positioned on the surface of the saddle according to the invention; it can be seen that the coccyx is at a reasonable distance from the surface of the saddle due to the presence of the hollow  21  ( FIG. 1 ) and that the gluteus muscles find an ergonomic support on the side surfaces of the saddle that slope downwards at an approximate angle of 45°-60°. The bridge plate  23  ( FIG. 5 ) that connects the two fixing plates  22 ,  22 ′, of the rail, will be used to display the manufacturer&#39;s trademark for marketing the saddle according to the invention.

     FIG. 12  shows the plan view of the touring saddle which has a non-limiting length of 20-22 cm, and with a non-limiting width of approximately 18-20 cm at the rear part, as well as the central channel ( 20 ) ( FIG. 1 ) which has a width of approximately 4-5 cm at the rear part and a width of approximately 2.5-3 cm at the front part. 
     FIG. 13  shows a plan view of the saddle according to the finding for amateur cyclists, which has a non-limiting width of approximately 14 cm at the rear part, terminating at the front parts with a non-limiting width of 3.5-4.5; the centre line channel  20  ( FIG. 1 ) has a width of approximately 3.5 cm at the rear part and a width of approximately 2.5 cm at the front part, and a non limiting length of 27 cm, while the non-limiting length for the women&#39;s model is 25 cm. 
     FIG. 14  shows the plan view of the competition racing saddle according to the invention which has a non-limiting width of 13 cm at the rear part, and a non-limiting length of 27 cm; the figure also shows the section of the construction detail in the position of points  8  and  8 ′ ( FIG. 1 ), wherein, in this position the internal side surfaces open from a lower position in an upward direction at an angle of 30° so that in this position the central channel  20 , ( FIG. 1 ), widens in the upper part as far as approximately 3 cm. 
   This aspect is important for professional athletes, who during training and races, almost always keep their trunk in a downward facing position, and this shape of the points  8 ,  8 ′,  FIG. 1 , permits the body of the penis to be housed in a satisfactory ergonomic space, preventing any compression of the deep dorsal vein and artery of the penis. 
   To satisfy the considerable request for bicycle saddles which should be as light as possible in weight,  FIG. 15  shows a longitudinal section of the shell made of carbon material only. In order to lighten the weight even further, the rear part that projects in an upward direction has been removed from the support rail  13  ( FIG. 5 ), which is provided with the saddle of this invention, and has been replaced with two elements that form an integral part of the shell in question (see  FIG. 15A ) which move in a downward direction until they are in contact with the rear part of the rail, which has a closed form at this point, and then they are fixed in the underlying part by a suitable plate held by two extra-light metal self-threading screws.
