Description

"E GONOMIC BICYCLE SEATBOARD FOR THE GLUTEI"

FIELD OF THE INVENTION

The present invention concerns an ergonomic bicycle seatboard for the glutei which can be used to substitute conventional bicycle saddles. The ergonomic seatboard for the glutei according to the present description allows to ride a bicycle in a perfectly comfortable way, preventing any potential damage to one's health connected to or deriving from conventional saddles.

BACKGROUND OF THE INVENTION

It is known that riding a bicycle brings benefits to one's health that are universally recognized. It is however also known that riding a bicycle, in the long run, can have negative effects on the health of the urogenital area. Medical opinions of acknowledged distinction estimate that a large number of possible pathologies can derive from using conventional saddles. Apart from specific illnesses, the prolonged compression of the perineal area caused by conventional saddles can increase the risk of prolapse of the pelvic floor and, at an advanced age, of urinary incontinence. The pelvic floor, positioned between the rectum and the genitals, is the meeting area between the lower limbs, and is characterized by the presence of a high number of subcutaneous organs; it is also the area where nerve, lymph, arterial and venous fascicles intersect, and supports the urinary bladder, the intestine, the anus and, in women, the uterus. The tonicity of the pelvic floor diminishes with age and also due to prolonged pressure, such as that produced upon it by conventional saddles for bicycles.

Nowadays bicycles are equipped with conventional saddles which are positioned under the pelvic floor. As discussed above, a constant and prolonged pressure on the pelvic floor can cause damage to one's health and various collateral problems, especially on the urogenital system in men. In particular, the most frequent health problems which affect amateur and professional cyclists may be hyperfusion and paraesthesia of the penis, scrotum, prostate and the perineal area in general, and also the possible increase in PSA (Prostate Specific Antigen) values.

In particular, it is known that current known saddles do not offer any concrete alternative to seating with a continuous weight pressure on the triangle of the perineum, despite the known attenuations of this potentially damaging effect that can be obtained by using known soft cushions, gels or stuffing, or hollows of various shapes and features in the saddle. In fact, these technical solutions only partly alleviate the pressure of weight on the perineal area: they are provided in correspondence to the position of the prostate and, although they only partly relieve the prostate area, they aggravate the weight load on peripheral areas of the pelvic floor, thus producing even worse damages.

The most frequent practical advice among cyclists is to adopt the precaution of standing in the saddle, every now and then, while you are cycling, to interrupt the pressure on the pelvic floor, modifying the seating posture and thus temporarily transferring the weight onto the pelvic basin or pelvic bones. However, this is just a momentary expedient which can even be dangerous from the point of view of stability and control of the bicycle, and it is certainly not a solution.

Moreover, it is important to underline that currently known saddles do not offer any possibility of adapting the posture, obliging the body of the cyclist to assume and maintain a specific seating position, which contributes to further congest the pelvic floor, which functions perennially as the only area of the body in contact with the saddle. Consequently, conventional saddles do not provide any possibility, for the cyclist, of adapting or reacting to the characteristics of the ride made on the bicycle.

It is particularly desirable, therefore, to offer a concrete alternative to sitting with continuous and static weight pressure on the zone of the pelvic floor, finding a radically different solution.

It is therefore necessary to provide an ergonomic bicycle seatboard for the glutei which at least partly solves the disadvantages of the prior art.

The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.

SUMMARY OF THE INVENTION

The present invention is set forth and characterized in the independent claims, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.

In accordance with the above purposes, forms of embodiment described here concern an ergonomic bicycle seatboard for the glutei which overcomes the limits of the state of the art and eliminates the defects therein. According to forms of embodiment described here, the ergonomic seatboard for the glutei comprises a seating plate and a support shaft. According to forms of embodiment described here, the support shaft is attached at a fixed angle of aperture to the seating plate in order to support and position the seating plate inclined downward, so as to confer upon it stability and a downward inclination in a front direction. The seating plate will therefore have a position such that its front part will be lower than its back part, in relation to the ground, so as to generate an inclination which can constitute an adequate support zone for the gluteus muscles.

DETAILED DESCRIPTION OF SOME FORMS OF EMBODIMENT

We shall now refer in detail to the various forms of embodiment of the invention, of which one or more examples are shown in the attached drawings. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, the characteristics shown or described insomuch as they are part of one form of embodiment can be adopted on, or in association with, other forms of embodiment to produce another form of embodiment. It is understood that the present invention shall include all such modifications and variants.

Forms of embodiment described here concern an ergonomic bicycle seatboard for the glutei 10 with an inclined configuration consisting of a seating plate 12 and a support shaft 13 (see figs, lc, 4, 5, 10, 11, 12, 13 and 14 for example).

According to some forms of embodiment, which can be combined with all the forms of embodiment described here, the support shaft 13 can be attached at a fixed angle of aperture a to the seating plate 12 in order to support and position the seating plate 12, thus providing the seating plate 12 with a structure inclined downward, that is with an inclination in the front direction. The seating plate will thus have a position such that its front part will be lower than its back part, in relation to the ground, so as to generate an inclination which can constitute an adequate support zone for the muscles of the glutei.

In possible implementations, the support shaft 13 can be attached at a fixed angle of aperture a to a lower surface 20 of the seating plate 12, or, in other possible implementations, the support shaft 13 can be attached to an edge of the ultra- flat seating plate 12, for example a lower, upper or lateral edge.

According to possible forms of embodiment, with reference for example to figs, lc, 4, 5, 10, 11, 12, 13 and 14, and which can be combined with all the forms of embodiment described here, the support shaft 13 can be positioned distant from the seating plate 12, that is, it can be external to the plan bulk, or to the vertical projection of the seating plate 12, or in any case it can be provided in correspondence to the external perimeter of the seating plate 12, therefore outside the area of the seating plate 12 destined to support the glutei.

In particular, it can be provided that the longitudinal axis X of the support shaft 13 is outside the plan bulk of the seating plane 12, or lying in correspondence to the perimeter thereof, so that, in any case, the support zone of the glutei on the seating plate 12 remains outside the longitudinal axis X of the support shaft 13.

For example, figs. 10 and 11 can be used to describe example forms of embodiment in which the longitudinal axis X of the support shaft 13 is outside the bulk of the seating plate 12. Figs. 12, 13 and 14 can be used to describe example forms of embodiment in which the longitudinal axis X of the support shaft 13 is peripheral and located near the perimeter edge of the ultra- flat seating plate 12, in the example on the lower edge.

According to possible implementations, the fixed angle of aperture a can be comprised and selected in an interval between about 20° and about 60°, in particular, between about 30° and about 55°, more in particular between about 35° and about 50°, even more in particular between about 40° and about 45°, or in other possible intervals comprised or overlapping within the intervals indicated.

According to possible forms of embodiment described here, the fixed angle of aperture a can be chosen by the user, at the time of purchase for example, inside one of the angular intervals indicated above; however, this will subsequently remain fixed for the user when he/she uses the seatboard.

Forms of embodiment described here refer to an ergonomic bicycle seatboard for the glutei 10 which allows to completely discharge the pressure acting on the triangle of the perineum, achieving an ergonomic effect that better accompanies the movement of the body during use of the bicycle. In particular, with the ergonomic seatboard for the glutei 10 according to the present description, a complete transfer of the pressure of weight from the perineum triangle to the glutei area is obtained, introducing the use of a body area for support which is much less delicate from an anatomical point of view and therefore less susceptible to physical problems (see for example figs. 2a. 2b and 2c).

Possible forms of embodiment, which can be combined with all the forms of embodiment described here, can refer to an ergonomic bicycle seatboard for the glutei 10 in which the seating plate 12 and the support shaft 13 can constitute a monoblock structure. For example, figs. 12, 13 and 14 can be used to describe example forms of embodiment in which the support shaft 13 and the ultra- flat seating plate 12 are a monoblock and constitute a single piece, without excluding that also fig. 1 1 can be used to describe forms of embodiment in which the support shaft 13 and the seating plate 12 are a monoblock.

In other possible forms of embodiment, which can be combined with all the forms of embodiment described here, the seating plate 12 can be of a variable thickness, flat or even ultra- flat, such as for example described using figs. 12, 13 and 14.

In other possible forms of embodiment, which can be combined with all the forms of embodiment described here, the seating plate 12 and the support shaft 13 can define a structure formed by two main parts connectable with respect to each other, such as described for example using figs, lc, 3, 4, 5, 6, 7, 8, 9, 10 and 1 1. In particular, in possible forms of embodiment, the seating plate 12 and the support shaft 13 can therefore be two separate parts, connected to each other in a releasable manner by means of an attachment device 21. The attachment device 21 can be formed by parts of said support shaft 13 and/or the seating plate 12 and by complementary coupling elements incorporated into the ergonomic seatboard for the glutei 10 described here.

In possible forms of embodiment, the support shaft 13 can be linear support shaft 13.

In other possible forms of embodiment, which can be combined with all the forms of embodiment described here, the support shaft 13 can be a support shaft 13 with two angled arms 15, 16 with a knee structure, which can for example allow a wide-range variable adjustment to the angle of inclination (fixed angle of aperture a), so as to guarantee achieving a variably inclined position.

In possible forms o'f embodiment, which can be combined with all the forms of embodiment described here, the seating plate 12 can advantageously have an ergonomic shape, so as to substitute flat surfaces with curved surfaces, to better accommodate the shapes of the body.

The ultra- flat seating plate 12 and the support shaft 13 can be disposed with respect to each other to define a certain inclination of the seating plate 12 at a fixed angle of aperture a, which allows to obtain a plurality of important advantages, among which for example:

- immediate solution to the physical problems concerning the perineum triangle;

- immediate relief of the pelvic floor;

- improved blood flow in the whole body of the cyclist, thanks to the absence of pelvic compression, eliminating unpleasant tingling sensations in arms and legs during the effort of pedaling;

- strengthening of the glutei muscles; - strengthening of the back;

- easy to use;

- more freedom of movement, since the inclination of the seating plate 12 allows a greater liberty of posture and consequent possibility of varying the seating posture, obtainable thanks to the possibility of sliding the buttocks along the surface of the seating plate 12;

- considerable increase in cycling performance: the active support function performed by the inclined seating plate 12 acts in opposition to the centrifugal force produced by the legs during pedaling, allowing the cyclist to develop a greater thrust on the pedals.

Forms of embodiment described here concern an ergonomic bicycle seatboard for the glutei 10 which allows to completely discharge the weight which affects the pelvic floor and the perineum triangle, so that cyclists no longer have to load the perineum triangle with their weight during use of the bicycle. Using the ergonomic bicycle seatboard for the glutei 10 according to the present description, the cyclist can completely, stably, and definitively transfer his entire pressure of weight from the perineum triangle to the area of the glutei, which is a much stronger muscular area and therefore less susceptible to potential problems or physical pathologies, much less delicate from an anatomical point of view, without nerves or subcutaneous organs.

Thanks to the inclined or downward configuration of the present invention, the ergonomic seatboard for the glutei 10 according to the present invention can become an active support component during pedaling. Therefore, one possible important difference between the present invention and the state of the art is that the ergonomic seatboard for the glutei 10 according to the present description exerts an active support function on the body of the cyclist, since the body of the cyclist supports itself by itself and is only resting against the inclined ergonomic seatboard for the glutei 10, and the weight of the upper body (trunk, upper limbs and head) is partly supported directly by the lower limbs, while a conventional saddle exerts an oppressive static support, since it supports all the weight of the body passively, and the lower limbs do not contribute in any way to supporting the weight of the upper body, the weight of which is entirely entrusted to the saddle. Thanks to the ergonomic seatboard for the glutei 10 according to the present description, the cyclist no longer puts stress on the pelvic floor when using the bicycle and can exploit the area of the buttocks as a much stronger area of the body, formed essentially of muscular tissues and without nerves or subcutaneous organs and therefore without medical contraindications, to give power to the pedals.

The ergonomic seatboard for the glutei 10 according to the present description provides a structure that, thanks to the special inclination or slope, guarantees a much greater freedom of posture compared to state of the art saddles. The cyclist can therefore adapt the posture of his body to the type of route or road that he/she is doing, adjusting his/her seating position to downhill or uphill, sliding freely and as desired along the seatboard, from the lower edge to the upper edge, and vice versa, in order to react better to the characteristics of the route.

The present invention therefore, is an ergonomic seatboard for the glutei which is sensibly inclined and not a saddle with a horizontal axis, and the difference between these two elements is that the ergonomic seatboard for the glutei implies a dynamic support, in which the body of the cyclist supports itself, while a saddle implies a static support, where the saddle supports the body of the cyclist passively and integrally. Instead, in the case of the seatboard, the body is not completely supported by the seatboard, which acts only as a rear resting and support element.

According to possible forms of embodiment, for example with reference to figs. 4- 1 1 and which can be combined with all the forms of embodiment described here, an attachment device 21 can be provided, consisting of two or more parts to attach the seating plate 12 to the support shaft 13, in the case where the latter are not made of a single piece, or monoblock (as described instead in figs. 12, 13 and 14).

According to possible implementations, the attachment device 21 can be configured to attach and adjust the seating plate 12 in a longitudinally sliding manner with respect to the support shaft 13.

According to forms of embodiment described here and which can be combined with all the forms of embodiment described here, a first attachment part of the attachment device 21 can be incorporated in the seating plate 12 or provided on a lower surface 20 thereof.

In possible forms of embodiment, the attachment device 21 can comprise an anchoring insert 22, a "slider" for example, formed for example by a longitudinal bar, which represents a first attachment part of the attachment device 21, and a longitudinal guide rail 24, formed for example by a longitudinal bar with a C- shaped cross section, that represents a second attachment part of the attachment device 21 , complementary to each other. For example, the longitudinal guide rail 24 can be formed by a pair of containing fins or by a longitudinal bracket.

For example, the first attachment part of the attachment device 21 can be the anchoring insert 22 or the longitudinal guide rail 24.

In possible forms of embodiment, the attachment device 21 can be formed by a slider-type sliding system with screwing, in which the anchoring insert 22 and the longitudinal guide rail 24 cooperate reciprocally sliding with respect to each other and an attachment system 25 can be provided, such as a screwing system 25 or equivalent, which selectively and releasably locks the desired position, or other attachment system already known to the state of the art.

According to possible forms of embodiment described here, and which can be combined with all the forms of embodiment described here, a second attachment part of the attachment device 21 can be provided on or incorporated into the support shaft 13.

According to forms of embodiment described here, the second attachment part of the attachment device 21 can be complementary to the first attachment part of the attachment device 21.

For example, the second attachment part of the attachment device 21 can be the longitudinal guide rail 24 or the anchoring insert 22.

The attachment device 21 according to forms of embodiment described here can allow a secure and reliable adjustment with longitudinal sliding. In this way it can be possible to obtain a variable distance between the seating plate 12 and longitudinal axis X of the support shaft 13.

According to possible forms of embodiment described here, and which can be combined with all the forms of embodiment described here, a screwing system 25 can be provided to attach the first attachment part to the second attachment part of the attachment device 21. The screwing system 25, of which one screw 26 for example is visible in figs. 7, 9 and 10, can thus allow the longitudinal sliding of the ultra- flat seating plate 12 and support shaft 13. The screwing system 25 can for example be driven by a knob 23, which can be provided on the head of the screw 26 (see fig. 10 for example).

According to possible forms of embodiment described here, and which can be combined with all the forms of embodiment described here, the anchoring insert 22 can be a perforated anchoring insert 22 provided with a plurality of perforations 27, or attachment holes, and the longitudinal guide rail 24 can be a perforated longitudinal guide rail 24 containing an equal or different number of perforations 28. The perforations 27, 28 can be provided to accommodate the screwing system 25 for example (see figs. 7 and 9 for example). For example, the perforated anchoring insert 22 can be inserted to size and made to slide in the perforated longitudinal guide rail 24 and the user can decide which perforations 27, 28 to use for the attachment using the screw 26, thus determining the relative position between anchoring insert 22 and longitudinal guide rail 24 and finally, the exact position of the seating plate 12 in relation to the support shaft 13.

According to possible forms of embodiment described here, and which can be combined with all the forms of embodiment described here, the anchoring insert 22 and/or the longitudinal guide rail 24 can be provided with additional contour edges configured to prevent the anchoring insert 22 from undesirably detaching and separating from the longitudinal guide rail 24. In this way, it is possible to obtain an even more secure anchorage of the two attachment parts. For example, it is possible to provide a dove-tail conformation for the edges of the anchoring insert 22 and/or the longitudinal guide rail 24. Moreover, the anchoring insert 22 and the longitudinal guide rail 24 can have various forms, shapes of sizes, according to needs.

According to forms of embodiment described here, the support shaft 13 can develop in the second attachment part of the attachment device 21.

For example, in possible implementations, the second attachment part can be provided on an upper arm 15 of the support shaft 13 with two arms.

In possible implementations, the upper arm 15 can develop in the second attachment part of the attachment device 21.

In possible implementations, the seating plate 12 can comprise an anchoring insert 22 or longitudinal guide rail 24 of the attachment device 21.

For example, forms of embodiment described using figs. 6 and 7, and which can be combined with all the forms of embodiment described here, can provide the anchoring insert 22 connected to the seating plate 12 and the longitudinal guide rail 24 associated with the support shaft 13.

Other forms of embodiment, for example described using figs. 8 and 9, and which can be combined with all the forms of embodiment described here, can provide the longitudinal guide rail 24 connected to the ultra- flat seating plate 12 and the anchoring insert 22 associated to the support shaft 13.

In possible implementations, the seating plate 12 can be provided with one or more coverings 14 (see for example figs, la and lb), such as a rigid or soft cushion, or a stuffing or even a rigid or soft covering or protection which covers it, either partly or completely.

According to possible forms of embodiment, the support shaft 13 with two arms can comprise a lower arm 16 and an upper arm 15, the upper arm 15 being attached at an angled position with respect to the lower arm 16 with said fixed angle of aperture a and applied to the seating plate 12, in particular to the lower surface 20 of the seating plate 12, or along one of the edges thereof. In particular, the upper arm 15 can be positioned parallel to the lower surface 20 of the seating plate 12.

In possible implementations, the lower arm 16 can be tubular, that is, shaped like a traditional tube, which can for example be inserted in the normal seating tube with which the frame of a bicycle is typically provided.

In possible implementations, the upper arm 15 itself can be shaped like a longitudinal guide rail 24 or like an anchoring insert 22 of the attachment device 21, mating with and complementary to the corresponding anchoring insert 22 or longitudinal guide rail 24 of the seating plate 12, to be inserted and secured to the seating plate 12.

Fig. 6 is used to describe example forms of embodiment of an attachment device 21 in which the anchoring insert 22 is attached to the seating plate 12 and the longitudinal guide rail 24 is provided on the upper arm 15.

Fig. 7 is used to describe example forms of embodiment of an attachment device 21 in which the perforated anchoring insert 22, attached to the seating plate 12, and the perforated longitudinal guide rail 24 are connectable by means of a screwing system 25 provided with a screw 26.

Fig. 8 is used to describe example forms of embodiment of an attachment device 21 in which the longitudinal guide rail 24 is attached to the seating plate 12 and the anchoring insert 22 is provided on the upper arm 15.

Fig. 9 is used to describe example forms of embodiment of an attachment device 21 in which the perforated longitudinal guide rail 24, attached to the seating plate 12, and the perforated anchoring insert 22 are connectable by means of a screwing system 25 provided with a screw 26.

According to possible forms of embodiment, the lower arm 16 and the upper arm 15 can be connected to each other by means of a central hub 18 (see fig. 3 for example), which can be mobile in order to adjust the angle, or it can be fixed, if it is provided that the angle is fixed and invariable. In particular, the central hub 18 can for example be mobile to define said knee structure of the support shaft 13, allowing to easily modify the angle between the two arms, obtaining the desired inclination. In possible forms of embodiment, the central hub 18 may not be provided and the lower arm 16 and the upper arm 15 can be connected to each other rigidly (see figs. 10 and 11 for example).

As we said, the possible inclination of the upper arm 1 , and therefore of the seating plate 12, can be in an interval between about 20° and about 60°, in particular between about 30° and about 55°, more in particular between about 35° and about 50°, even more in particular between about 40° and about 45°, or in other possible intervals comprised or which overlap inside the stated intervals. Fig. 3 is used to describe example forms of embodiment of a support shaft 13 with two arms with a mobile knee structure which can allow an easy adjustment of the angle between the two arms 15, 16 of the support shaft 13, therefore determining the inclination of the seating. The lower arm 16 is provided, shaped tubular for example, the central hub 18, the upper arm 15 and the arrow shows the possibility of inclination defined by the fixed angle of aperture a.

Fig. 4 is used to describe example forms of embodiment in which the anchoring insert 22 is attached to the seating plate 12, and the upper arm 15 is shaped to define the longitudinal guide rail 24, and the central rotation hub 18 can be provided and the lower arm 16 shaped tubular for example. Fig. 5 is used to describe example forms of embodiment in which the longitudinal guide rail 24 is attached to the seating plate 12, and the upper arm 15 is shaped to define the anchoring insert 22, and the central rotation hub 18 can be provided and the lower arm 16 shaped tubular for example.

In possible other forms of embodiment, the lower arm 16 and the upper arm 15 can be rigidly connected to each other, that is, they can be a single body, and therefore the angle between lower arm 16 and upper arm 15 can be fixed, definable during production and then unchangeable during use. For example, the lower arm 16 and the upper arm 15 can be made solid with each other using known techniques, for example by welding.

Figs. 10 and 1 1 can be used to describe example forms of embodiment, which can be combined with all the forms of embodiment described here, in which the upper arm 15 and the lower arm 16 are connected to each other in a rigid and fixed manner, for example by welding.

According to forms of embodiment described here, and which can be combined with all the forms of embodiment described here, the seating plate 12 can be provided with a single, linear uniform surface.

According to other forms of embodiment described here, and which can be combined with all the forms of embodiment described here, the seating plate 12 can be divided into two or more separate deflectors.

According to forms of embodiment described here, the seating plate 12 can have a central depression 12a and two lateral wings 12b (see figs, lc, 4 and 5 for example).

According to forms of embodiment described here, the seating plate 12 can be of variable shape, both in terms of profile and shape of the depression, if provided.

According to forms of embodiment described here, the seating plate 12 and the support shaft 13, like the possible attachment device 21, if provided, can be made of various thicknesses, design, shapes, materials and sizes, according to needs. According to forms of embodiment described here, and which can be combined with all the forms of embodiment described here, in the case where the seating plate 12 and the support shaft 13 are made in a single piece or monoblock, the support shaft 13 can have a single structure, as described above, or a double, triple or multiple form, that is, with other arms 115 as well as the upper arm 15 as above, such as described using fig. 15 for example.

Fig. 16 is used to describe forms of embodiment in which the second attachment part of the attachment device is formed by a guide groove or seating 30, made in the thickness of the seating plate 12, in particular in the lower surface 20 thereof, for example by removing material, in particular milling. The guide groove 30 can carry out essentially the same function as the longitudinal guide rail 24, only that, unlike the latter, it does not protrude from the seating plate 12, but is comprised in the bulk of the seating plate 12, in that it is made in its thickness.

In this case, the anchoring insert 22 can be inserted in length sliding in the guide groove 30 and attached in the desired position selected on each occasion, using the screwing system 25 described above for example, or an equivalent system.

As seen in fig. 16, the attachment holes 28 can be obtained on the bottom of the guide groove 30 to accommodate the screws 26 of the screwing system 25. The anchoring insert 22, in this way, is embedded inside the guide groove 30, and is for example flush with the lower surface 20 of the seating plate 12, or slightly protruding therefrom.

It is clear that modifications and/or additions of parts may be made to the ergonomic seatboard for the glutei 10 as described heretofore, without departing from the field and scope of the present invention.

It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of ergonomic seatboard for the glutei 10, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
