Physical exercise device simulating the use of a bicycle

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a physical exercise device simulating the use of a bicycle.

[0002] Physical or gymnastic devices or implements, provided with pedals allowing a user to pedal with physical movements like those of a bicycle, are already known.

[0003] These prior devices or implements conventionally comprise a supporting frame, which supports a seat, a handlebar as well as a pair of pedals, which elements are arranged with an arrangement similar to that of the seat, handlebar and pedals of a conventional bicycle.

[0004] However, this bicycle-like frame, instead of including wheels, is provided with a supporting base statically supported on a floor, so as to allow a user to perform, even in a comparatively small size closed room, gymnastic exercises, like those performed in cycling.

[0005] The above mentioned bicycle-like devices or implements are broadly diffused since they allow to perform, at any desired times, physical or gymnastic exercises, like those performed on a bicycle, without compelling the user to follow high traffic roads, and without the effects of meteorological agents.

[0006] On the other hand, notwithstanding the above mentioned advantages, the mentioned prior physical exercise devices have the drawback that they do not allow to exercise all of the body muscles which, on the contrary, would be properly exercised on a conventional bicycle.

[0007] In fact, since the construction of the prior devices is of a static type, the exercises performed thereon do not involve all of the body muscles which are involved in the use of a conventional bicycle, for example the muscles allowing the bicycle to be held in a balanced or equilibrium condition, both in a vertical attitude and in a slanted attitude, for example on curved portions of roads and the like.

[0008] In this connection it should be apparent that in a slanted position, which can not be assumed in the mentioned prior devices, the body muscles would operate in a different manner from the operation in a vertical attitude.

[0009] Document DE 29 813 828 U discloses an example of a physical exercice device.

SUMMARY OF THE INVENTION

[0010] Accordingly, the aim of the present invention is to solve the above mentioned problem, by providing a physical exercise device or implement adapted to fully simulate the use of a conventional bicycle, thereby allowing to properly exercise all of the muscles which are usually involved in the use of a conventional bicycle.

[0011] Within the scope of the above mentioned aim, a main object of the present invention is to provide such a physical exercise device which is also adapted to exercise those body muscles which, in the use of a conventional bicycle, cooperate to hold the bicycle in an equilibrium condition, both as the bicycle is driven on a rectilinear road and as it is driven on curved parts of the road.

[0012] Another object of the present invention is to provide such a physical exercise device which is very safe and reliable in operation.

[0013] Yet another object of the present invention is to provide such a physical exercise device which can be easily used in comparatively small size closed rooms.

[0014] According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a physical exercise device according to claim 1

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] With reference to the number references of the above mentioned drawing figures, the physical exercise device or implement, according to the present invention, comprises a supporting frame 1, which includes a seat 2, a handlebar 3 as well as a pair of pedals 4, which elements are arranged likewise to the arrangement of the seat, handlebar and pair of pedals of a conventional bicycle.

[0017] Thus, the frame 1 is substantially made as the prior implements simulating a bicycle.

[0018] However, differently from prior bicycle like devices, the frame 1 of the device according to the invention is provided with supporting means, allowing the frame 1 to swing, in operation, in its longitudinal middle plane and/or transversely of said longitudinal middle plane.

[0019] As is clearly shown in Figure 1, said supporting means can comprise a pair of curved elements 5a and 5b which have their bottom end portions coupled to the base 6 of the frame 1 and being arranged transversely of the longitudinal middle plane of said frame 1.

[0020] The two curved elements 5a and 5b are arranged parallel to one another and are spaced from one another along the longitudinal extension of the frame 1.

[0021] The two curved elements 5a and 5b bear by their curved side on the floor, so as to allow, in operation, the supporting frame 1 to swing transversely of its longitudinal middle plane.

[0022] As is clearly shown in Figure 3, the curved elements, which in this figure have been indicated by the reference numbers 7a and 7b, can be directly formed in the base 6 of the supporting frame 1.

[0023] Figure 2 illustrates another embodiment in which the supporting means of said frame 1, which, likewise to the embodiments shown in Figures 1 and 3 will allow the frame 1 to swing transversely of its longitudinal middle plane, comprise a curved supporting element 8, bearing by its curved side against the floor and being connected at the bottom to the base 6.

[0024] During the operation of the embodiment shown in Figure 2, the swinging of the frame 1 is obtained, instead of using a pair of curved elements 5a, 5b or 7a, 7b, by a continuous curved surface, the curvature axis thereof substantially lies in the longitudinal middle plane of the frame 1.

[0025] The base 6 is preferably formed by a pair of cross members 9a, 9b, parallel to one another and spaced from one another along the longitudinal extension of the frame 1, and being coupled at the central portion thereof by a longitudinal middle beam 10.

[0026] In the embodiment shown in Figure 6, the supporting means comprise a cup-like member 11 which is coupled, by its base, to the bottom of a plate 12, in turn connected under the base 6.

[0027] The cut-like element 11 is preferably coupled to a central region of the base 6, so as to allow the implement frame to swing in any desired directions.

[0028] In Figure 7, the supporting means comprise a pair of cup-like elements 13a and 13b, which are coupled at the bottom thereof to the base 6 and being spaced from one another along the longitudinal extension of the implement.

[0029] In Figure 8, the base 6 is pivoted to the bearing foot elements 14a and 14b about a pivot axis 15, which is substantially horizontal and lies in the longitudinal middle plane of the frame 1, so as to allow said frame 1 to swing about said pivot axis 5.

[0030] Figure 9 illustrates another embodiment in which the swinging movement of the frame 1, both longitudinally and transversely, as well as in a composite manner with respect to the mentioned two swinging directions, is obtained by four resilient bearing foot elements, comprising springs 16 spaced from one another and from the longitudinal middle plane, as well as from the transversal or cross middle plane of the frame 1.

[0031] Figure 10 illustrates yet another embodiment, similar to that shown in Figure 2, where the supporting means comprise a curved supporting element 17 which, in this case, is provided with a curvature axis perpendicular to the longitudinal middle plane of the frame 1.

[0032] Figures 11 to 14 illustrate yet another embodiment of the physical exercise device according to the present invention, in which the supporting means comprise a pair of curved supporting elements 18 and 19 which are diagonally coupled at the bottom of the base 6, so as to define two curved bearing surfaces for the base 6.

[0033] The curved supporting elements 18 and 19 cross one another at a central vertical axis of the frame 1 and define two bearing curved surfaces, having curvature axes respectively parallel and perpendicular to the longitudinal middle plane of the frame 1, to allow said frame 1 to swing both in its longitudinal middle plane and transversely of said longitudinal middle plane.

[0034] The physical exercise device according to the present invention further comprises limiting means for limiting the swinging amplitude of the frame 1.

[0035] Said swinging amplitude limiting means can merely comprise, as shown in Figure 3, side extensions of the cross members 9a and 9b of the base 6, or they can also comprise suitable extensions 20, 21 coupled to the end portions of the cross members 9a and 9b of the base 6, as shown in Figures 4 and 8.

[0036] In Figure 5, in addition to the extensions 20, side bearing foot elements 22 are moreover provided, said side bearing foot elements being coupled to the extensions 20 and projecting at the bottom thereof.

[0037] The foot elements 22, in a vertical equilibrium condition of the frame 1, are spaced from the floor, and they can be of a height adjustable type, in order to allow the swinging amplitude of the frame 1 to be easily adjusted or changed.

[0038] In the embodiment shown in Figure 8 springs 23 are provided to counter-bias the swinging movement in a set direction, or in another set direction, of the frame 1 about the pivot axis 15.

[0039] From the above disclosure and from the figures of the accompanying drawings, it should be apparent that the invention fully achieves the intended aim and objects.

[0040] In particular, the fact is to be pointed out that a physical exercise device or implement has been provided which, owing to the capability thereof of swinging longitudinally, transversely, or in a composite manner along the two mentioned swinging directions, would allow all of the body muscles to be exercised or affected, likewise in a conventional type of bicycle.

[0041] While the invention has been disclosed and illustrated with reference to several embodiments thereof, it should be apparent that the disclosed embodiments are susceptible to many modifications and variations, all of which will come within the scope of the appended claims.
