Description

SADDLE FOR A BICYCLE

DESCRIPTION

Field of application

The present invention regards a saddle for a bicycle in accordance with the preamble of the independent claim.

The present saddle is inserted in the industrial field of production of bicycles and in particular in the field of components for bicycle frames, preferably of high technology type, and advantageously but not exclusively usable for a professional use, i.e. for racing bicycles or more generally for competition bicycles.

State of the art

As is known, bicycle saddles are generally formed by a rigid or semi-rigid body which constitutes the lower part of the saddle and which in the technical jargon of the field is termed with the name "hull", and by a padding, which is fixed above the hull and is for example made of an expanded elastomeric material.

The saddle is then conventionally connected to the bicycle frame by means of fixing means which are arranged below the hull. Generally, such fixing means comprise a seat post reinforcement formed by a pair of shaped bars or by a single bar bent on itself, known in the technical jargon of the field with the name "fork". This reinforcement is usually mechanically connected on the front and back to the hull of the saddle by means of screws or rivets, and in an intermediate position by means of a clamp to a steering column or seat post tube, in turn mechanically connected to the bicycle frame.

In order to decrease the weight of all the components which constitute the bicycle, especially in the case of racing or competition bikes, composite materials are currently used which in particular are carbon fiber provided with very limited weight and high mechanical performances.

For example, it is known from the patent JP H02145321 to make the seat post reinforcement of plastic reinforced in carbon fiber, or it is known from the patent CN 2737646 to make the seat post steering column of carbon fiber.

It is also known from the patent WO 2017213315 to make a saddle for a bicycle made of carbon fiber. More in detail, the saddle internally delimits an empty space obtained by means of a thin sheet of carbon fiber shaped in the form of the saddle. The saddle comprises an abutment portion on which a user sits and a support portion which is formed integral with the abutment portion and is fixed to the upper part of a seat post steering column by means of a seat post reinforcement.

It is known for example from CN 204623628 to make saddles comprising a hull made of plastic material and a cover with cushion function made of carbon fiber. The hull is connected to the seat post steering column by means of a normal fork seat post reinforcement. It is known, for example from IT 1324279, to make fork seat post reinforcements of carbon fiber possibly to be covered with a metallic reinforcement mesh at the anchorage zone of the clamp for the mechanical connection of the fork to the seat post steering column.

Also known from DE 20000745 is a bicycle saddle which comprises an abutment portion provided below a support rod integral with the abutment portion and intended to be inserted in the seat post steering column and to be fixed to the latter by means of horizontal screws. The saddle can be provided with elastic elements between the abutment portion and the support rod in order to damp stresses due to the roughness of the terrain.

Also known from NO 20110869 is a saddle made of carbon fiber, in which the abutment portion and the support portion are connected by forming, on the back and front, junction angles less than 90°, in a manner such to allow the abutment portion to have a certain elasticity with respect to the stem portion.

The saddles of known type described briefly above have in practice demonstrated that they do not lack drawbacks.

A first drawback lies in the fact that such saddles of known type do not reconcile the need for lightness with the needs for satisfactory mechanical performances, in particular with reference to the damping response that the saddle must have.

Presentation of the invention

In this situation, the problem underlying the present invention is therefore that of overcoming the drawbacks shown by the solutions of known type, by providing a bicycle saddle which has extremely limited weight.

Further object of the present invention is to provide a bicycle saddle, which is particularly strong mechanically. Further object of the present invention is to provide a bicycle saddle which optimally damps the roughness of the terrain.

Further object of the present invention is to provide a bicycle saddle which is comfortable.

Further object of the present invention is to provide a bicycle saddle which is simple to mount and is entirely reliable in operation.

Detailed description of a preferred embodiment

In accordance with the figures of the enclosed drawings, reference number 1 overall indicates a saddle for a bicycle, object of the present invention.

This is intended to be mechanically connected to the steering column or seat post tube 2 of the frame of a bicycle.

The saddle 1 comprises a hull 3 made of rigid or semi-rigid material and fixing means 4 arranged below the hull 3 and adapted to connect the latter to the seat post tube 2 of the bicycle.

More in detail, the seat post tube 2 is known to be provided with a lower end, which is usually adjustably inserted in a tubular seat of the bicycle frame, and an upper end, which carries, mechanically associated therewith, a head 2’, e.g. via welding (or only as shaped end), on which the aforesaid fixing means 4 of the saddle 1 are typically mounted.

In accordance with the idea underlying the present invention, the hull 3 is made of a composite material, i.e. preferably entirely of a single composite material such as carbon fiber, glass fiber, Kevlar etc.. For example, the composite material comprises multiple superimposed layers of carbon and Kevlar.

The hull 3 comprises two portions 30, 31 integral with, in particular obtained with superimposed layers of composite material and in particular of carbon fiber, sized and with fibers oriented in order to confer the desired mechanical performances to the different parts of the hull 3.

For example, the different layers of carbon fiber fabrics, pre-impregnated with resin, will have shapes and superimposition in order to vary the mechanical performances as a function of the areas of the hull. For example, larger thicknesses will be used, advantageously also with stronger fibers at the plate-like portion 30 in proximity to the connection with the stem portion 31, given that in such zone the load of the weight of the cyclist is transferred from the seat to the tube.

The selection of the layers or of the type of composite material, such as for example advantageously the carbon fiber and the relative resin to be used, can vary depending on the characteristics of the hull 3 that one wishes to attain and depending on the use destination of the saddle, i.e. for example for racing bikes, for mountain bikes, for professional competition bikes or for leisure bikes.

More in detail, the hull 3 comprises a sheet-like portion 30 shaped for defining the seat of the cyclist user and a stem portion 31, which is integral - without interruption - with the sheet-like portion 30, is mechanically connected to the fixing means 4, and projects below the sheet-like portion 30.

Considering, at first glance, that the sheet-like portion 30 defines a sitting plane, which in particular is substantially horizontal, the stem portion 31 is extended below said plane with a vertical component.

The stem portion 31 is shaped and sized for being elastically pliable with regard to the stresses transmitted to the hull 3 through the fixing means 4 and of course through the bicycle frame and due to the roughness of the terrain, so as to damp such stresses and facilitate the comfort of the user cyclist. Due to the present invention, the damping means which are normally integrated in the means for fixing the hull 3 to the seat post tube 2 are instead obtained with a stem portion 31 integral with the remaining sheet-like portion 30 of the same hull 3.

In this manner, the components are reduced, entirely to the advantage of the structural and mounting simplicity of the saddle 1 and in particular reducing the overall weight of the saddle 1.

The sheet-like portion 30 of the hull 3 has a main longitudinal extension which is extended, along a longitudinal extension direction Y, from an enlarged rear portion 3 A to a tapered front portion 3B.

Advantageously, the sheet-like portion 30 is provided with two lateral edges 30’, which are placed to connect the enlarged rear portion 3 A with the tapered front portion 3B and are extended, along the longitudinal extension direction Y, on two opposite sides of the sheet-like portion 30 itself.

The stem portion 31 of the hull 3 is advantageously obtained with two or more ribs 31 A, 31B.

Such ribs comprise at least two lateral ribs 31 A, 3 IB. These are preferably extended, in accordance with the illustrated embodiments, along the longitudinal extension direction Y. With such expression, it must not be intended that the two ribs 31 A, 3 IB must be parallel to the longitudinal extension direction Y but only that they have a main component in such direction in order to follow the elongated extension along such longitudinal extension direction Y that has the saddle 1.

In accordance with the embodiment of figures 1-19, the stem portion 31 comprises two lateral ribs 31 A, 3 IB, each of which is extended, along the longitudinal extension direction Y, with elongated shape, preferably without interruptions.

In accordance with the embodiment illustrated in figures 20 and 21, the ribs are lateral and there are four of them, indicated with 31 A, 31 A’, 31B, 31B\

Slots 33 can be provided in the aforesaid ribs 31 A, 31 A’, 3 IB, 3 IB’.

Of course, without departing from the protective scope of the present patent, a higher number of such ribs could also be present.

Each of the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’ is extended, in particular in the form of a wall, from an upper edge 31”, connected to the sheet-like portion 30, to a lower edge 31’.

The stem portion 31 also comprises an anchorage wall 31C, which is substantially parallel to the sheet-like portion 30 and connects the lower edges 3 G of the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’, defining a through opening 32. The latter has an extension with an axis Y’ substantially parallel to the longitudinal extension axis Y of the sheet-like portion 30 of the hull 3.

The anchorage wall 31C is engaged by the fixing means 4 in order to allow fixing the hull 3 to the tube 2.

Advantageously, the stem portion 31 is extended, along the longitudinal extension direction Y, between an open rear edge 311 and an open front edge 312, between which the through opening 3 is extended in a through manner along the axis Y’, substantially in the form of a channel. In particular, each open edge 31 A, 3 IB is defined by respective front/rear edges of the anchorage wall 31C and of the lateral ribs 31 A, 31 A’, 31B, 3 IB’.

More in detail, the through opening 32 is delimited above the sheet-like portion 30, below the anchorage wall 31C and at the sides by the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’, being extended, along the axis Y’ thereof, between two passages delimited by the corresponding open edges 311, 312 of the stem portion 31. Advantageously, the ribs 31A, 31A’, 31B, 31B’ are extended, starting from the corresponding upper edges 31”, from the corresponding lateral edges 30’ of the sheet-like plate 30 to the two lower edges 3 G of connection with the anchorage wall 31C.

Each lateral rib 31 A, 31 A’, 3 IB, 3 IB’, along its entire extension from the upper edge 31” to the lower edge 3 G, is inclined with respect to the anchorage wall 31C, defining with the latter, inside the through opening 32, an obtuse inclination angle a.

In particular, each lateral rib 31 A, 31 A’, 3 IB, 3 IB’ has the aforesaid inclination at the lower edge 3 G of connection to the anchorage wall 31C.

The inclination angle a is delimited between the internal surfaces (which face the through opening 32) of the coupling wall 31 and of the corresponding lateral rib 31 A, 31 A’, 3 IB, 3 IB’, hence extended within the through opening 32. The inclination angle a is defined on the transverse section of the stem portion 31, obtained on a plane orthogonal to the longitudinal extension direction Y. Advantageously, the aforesaid inclination angle a is substantially comprised between 175° and 100°.

Preferably, with reference to the examples of the enclosed figures, the lateral rib 31 A, 31 A’, 3 IB, 3 IB’ has transverse section variable along its extension along the longitudinal extension direction Y. Consequently, in particular, the inclination angle a varies, preferably progressively, along the extension direction Y, in particular at the lower edge 3 G of the lateral rib 31 A, 31 A’, 3 IB, 3 IB’.

In any case, the values that the inclination angle a assumes, along the extension of the lateral rib 31 A, 31 A’, 3 IB, 3 IB’ along the longitudinal extension axis Y, are always those of an obtuse angle (greater than 90° and less than 180°).

Advantageously, the inclination angle a varies, preferably in a continuous manner, between a first angle value VI comprised between 170° and 175° at the open rear edge 311 of the stem portion 31, and a second angle value V2 comprised between 100° and 140° at the open front edge 312 of the stem portion 31.

The inclination of the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’ according to the present invention ensures that the stresses that are transmitted to the stem portion 31 by the ground (through in particular the fixing means 4) or by the weight of the cyclist (through the sheet-like portion 30) always act substantially in bending the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’. Consequently, following the aforesaid stresses, the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’ are subjected to bending forces which determine appropriate elastic deformations of the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’ made of composite material, allowing damping the stresses and facilitating the comfort of the cyclist.

Advantageously, each lateral rib 31 A, 31 A’, 3 IB, 3 IB’, along its entire extension from the upper edge 31” to the lower edge 3 G, is inclined with respect to the sheet-like portion 30, defining with the latter, inside the through opening 32, an acute lateral angle

In particular, each lateral rib 31 A, 31 A’, 3 IB, 3 IB’ has the aforesaid inclination, at the upper edge 31” of connection to the sheet-like portion 30.

The lateral angle b is delimited between the internal surfaces (which face the through opening 32) of the sheet-like portion 30 and of the corresponding lateral rib 31 A, 31 A’, 3 IB, 3 IB’, hence extended within the through opening 32. The lateral angle b is defined on the transverse section of the stem portion 31, obtained on a plane orthogonal to the longitudinal extension direction Y.

Advantageously, the lateral angle b is substantially comprised between 10° and 40°. Suitably, the lateral angle b varies, preferably progressively, along the extension direction Y (in particular following the variation of the shape of the transverse sections of the lateral rib 31 A, 31 A’, 3 IB, 3 IB’), in any case maintaining acute angle values.

The acute lateral angle b between the sheet-like portion 30 and the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’ further determines a stress of the latter by means of bending forces, hence ensuring a suitable elasticity of the stem portion 31.

Advantageously, the upper edge 31” of each lateral rib 31A, 31A’, 31B, 31B’ forms a sharp edge with the corresponding lateral edge 30’ of the sheet-like plate 30, with the tip of such edge directed towards the exterior of the hull 3.

Advantageously, each lateral rib 31 A, 31 A’, 3 IB, 3 IB’ has transverse section, obtained on a plane orthogonal to the longitudinal extension direction Y, with substantially curved shape with convexity directed towards the through opening 32. In particular, therefore, each lateral rib 31 A, 31 A’, 3 IB, 3 IB’ is externally concave, being joined to the corresponding lateral edge 30’ of the sheet-like portion 30 by means of the aforesaid sharp edge.

Advantageously, the enlarged rear portion 3A of the sheet-like portion 30 is extended (along the longitudinal extension direction Y) cantilevered from the stem portion 31, and the tapered front portion 3B of the sheet-like portion 30 is extended (along the longitudinal extension direction Y) cantilevered from the stem portion 31 in the opposite direction with respect to the enlarged rear portion 3 A.

In particular, the enlarged rear portion 3 A is extended projectingly with respect to the open rear edge 311 of the stem portion 31, and the tapered front portion 3B is extended projectingly with respect to the open front edge 312 of the stem portion 31 itself.

Preferably, the enlarged rear portion 3A and the tapered front portion 3B are extended projectingly, respectively from the open rear edge 311 and from the open front edge 312, for a protrusion distance (along the longitudinal extension direction Y) greater than or equal to 1/5 of the length of the sheet-like portion 30 (along the longitudinal extension direction Y), in particular greater than or equal to about 1/4 of the length of the sheet-like portion 30, and still more particularly between about 1/4 and 1/3 of the length of the sheet-like portion 30.

The aforesaid projecting configuration of the enlarged rear portion 3 A and of the tapered front portion 3B allows such portions 3A, 3B to bend more greatly than the remaining part of the sheet-like portion 30, ensuring greater comfort for the cyclist. Advantageously, the stem portion 31 is arranged, along the longitudinal extension direction Y, in an intermediate position between the enlarged rear portion 3A and the tapered front portion 3B, in particular in a manner such to be arranged on the point of greatest application of force by the cyclist during bicycle use.

Preferably, the stem portion 31 has length, along the longitudinal extension direction Y, comprised between 20% and 45% of the length of the sheet-like portion 30.

In particular, by length of the stem portion 31 it is intended the length of the latter (between its open lateral edges 311, 312) at the upper edge 31” of the lateral ribs 31A, 31A’, 3 IB, 3 IB’.

Advantageously, the length of the stem portion 31 is reduced from the upper edges 31” to the lower edges 3 of the lateral ribs 31 A, 31 A’, 3 IB, 3 IB’.

Preferably, the length of the stem portion 31 along the lower edges 3 (which advantageously correspond to the length of the anchorage wall 31C) is comprised between 25% and 40% of the length of the sheet-like portion 30 and in particular is equal to about 33% of the length of the latter.

In accordance with the three embodiments of figures 1, 10 and 12, the fixing means 4 can provide for different configurations, even different from those exemplifyingly described above. These in any case share the same characteristic of connecting the seat post tube 2 to the stem portion 31 of the hull 3.

Preferably, in accordance with all the embodiments illustrated in the enclosed figures, the fixing means 4 comprise at least one plate 40 inserted in the through opening 32 in abutment above the anchorage wall 31C.

The abovementioned anchorage means 4 also advantageously comprise a counter-plate 41, which is mounted in abutment beneath the anchorage wall 31C of the stem portion 31 and is advantageously fixed to the plate 40 by means of screw means 42, for example by two screws in accordance with the embodiments of the enclosed drawings. Advantageously, the anchorage wall 31C is provided with at least one passage opening crossed by the fixing means 4 (in particular by the screw means 42) in order to fix the stem portion 31 to the tube 2, and in particular in order to fix the plate 40 to the counter plate 41. Adjustments of the position of the saddle 1 are provided for so that the cyclist can select the optimal position of the saddle 1. Such position is defined by the cyclist as a function of his/her physiognomy and on his/her biking comfort preferences. The adjustment of the position of the saddle 1 provides for a height adjustment, an adjustment of the tilt with respect to the seat post support and a forward and backward adjustment in order to vary the distance of the saddle with respect to the handlebar.

The height adjustment is for example obtainable in a conventional manner, by varying the length of the tube 2 part that is inserted in the provided tubular seat of the bicycle frame.

The forward or backward adjustment of the saddle with respect to the handlebar and the adjustment of the tilt of the saddle with respect to the seat post tube 2 are obtained as specified herein with respect to the preferred but non-limiting embodiments of the enclosed figures.

In order to allow adjusting the position of the hull 3 of the saddle in the longitudinal extension direction Y, the anchorage wall 31C is preferably provided with two corresponding elongated slots 310 (advantageously defining the aforesaid passage opening), which are crossed by the stems of the screws 42 in order to tighten the anchorage wall 31C and hence the hull 3 in different longitudinal positions, i.e. with the hull 3 more forward or backward.

For the adjustment of the tilt of the hull 3, the fixing means 4 advantageously comprise a curved support 43 mechanically coupled with the counter-plate 41, which allows rotating the hull 3 around a horizontal axis, orthogonal with respect to the axis of longitudinal extension Y of the saddle 1.

More in detail, in accordance with the embodiment of figure 10, such curved support 43 is made on the head T of the seat post tube 2, in particular in the form of a cylindrical pin transverse to the extension of the tube 2. This supports the counter-plate 41. The latter can be locked in the desired tilted position by means of two lateral jaws 44 connected with screws 45 to the lateral ends of the curved support 43 and susceptible of gripping two below-projecting sides 46 of the counter-plate 41.

In accordance with the embodiment of figure 12, such curved support 43 is made on the head T of the seat post tube 2 in the form of a curved guide, according to a circular arc profile. A slide 47 is engaged thereon, which is fixed with screws 48 to the counter- plate 41 in order to adjust the angular position of the hull 3 of the saddle 1.

In accordance with the embodiments of the enclosed figures, the hull 3 is provided with an elongated central slot 300 in the longitudinal extension direction Y of the same hull 3 and which in particular affects the ischial zone.

The hull 3 can also be advantageously covered by a padding layer 10 which is visible in the enclosed figures 14-19.

The invention thus conceived therefore attains the pre-established objects.
