Description

The present invention relates to a bicycle

static gymnastics.

  The gymnastic bicycle offered by the

  vention is of the type used in sports gymnasiums and in private homes to constitute a device

  static by means of which different exercises can be carried out

physical cices.

  Generally speaking, the gymnasium bicycle

  tick of the invention is constituted in such a way that it has three fundamental aspects, one of which relates to the chassis or frame which has a special configuration

  which will be commented on later. Another fundamental aspect

  rate of the bicycle consists of means which apply a vibration to the user when the latter acts on the

  means in question, while the third fundamental aspect

  tal of the bicycle consists of a particular form of

  means of supporting the assembly on the ground.

  With regard to the chassis or general frame of the bicycle, which constitutes the first fundamental aspect thereof, this chassis or this frame is constituted by a

  elongated and curved part whose cross-section

  dirty defines a kind of ellipsoid This part has at one of its ends a narrower part which gives rise to the formation of a small section extension

  transverse in the shape of an inverted "U", while its end

  opposite mity is extended to a semi-circular cross

  area by means of which the fixing of a

  lug secured to the corresponding support means or means

  dants This component part of the frame or chassis pre-

  path, near the semicircular crosspiece in question

  tion, a longitudinal opening provided on one of its lateral edges with notches which determine the different fixing positions of the lever for adjusting the greater or lesser resistance that the system of

pedaled.

  Near the end which has the narrower part of the part in question, from

  which constitutes the frame, are fixed collaterally-

  The ends of each of the tubular elements which, accompanying the narrower end of the part in question, are provided with a curvature which extends until their opposite ends reach another semi-circular transverse part over 11 here the other is fixed

bicycle dropout.

  From the chassis or from Cr crm emerge the pro-

  lengths or rrssondondants tubular elements at the ends of which is provided the fi -, Lor of the saddle

and handlebars respectively.

  This structure of the chassis or of the general frame of the bicycle has an extremely aesthetic appearance and in addition is of advantageous configuration compared to

  chassis or frames used in gym bicycles-

conventional nastics.

  As regards the means which apply a vibration to the user and which constitute another of the fundamental aspects of the invention, these means are designed in a simple manner and based on the existence of the conventional elements of a bicycle. gymnastics of this type, and therefore, due to the design of these means, the user can very easily place them in the active position to produce the vibration or in the inactive position to simply perform a pedaling exercise or even an exercise of rowing, all these operations can be carried out by the user from the handlebars without the need to dismount, which would interrupt the

continuity of its exercises.

  It is well known that the vibration of bicycles-

  your gymnastics statics is obtained by establishing a

  continuous contact between a bearing provided in the lower part

  of an extension derived from the handlebar structure

2545727.

  and a polygonal plate secured to the pedals This continuous contact can be achieved because the entire handlebars

  is articulated on a structure fixed to the chassis or

  dre of the bicycle, being provided a spring which elastically maintains this bearing contact between the bearing and the polygonal plate, independently of the fact that this spring

  constitutes an antagonistic spring against which it is pos-

  likely to do the rowing exercise when the rollover

  and the polygonal plateau in question are not in contact.

  However, in the vibration system described above, the means which serve to create this vibration have the peculiarity that a stud is provided on the fixed structure of the bicycle.

  mounted between two elongated notches between which

  it can move under the effect of a traction cable connected to one of the handlebars, which means that, in

  depending on the position of this stud, the bearing that

  door the lower handlebar structure will come in

  contact or not to come into contact with the poly-

  gonal, and therefore the offset may or may not produce

vibration.

  The movement of the control cable takes place in the opposite direction to the action of a small spring which tends to cause the stud in question to occupy the lowest position when it is free, a position which corresponds to the production of vibration. and in which the end of the stud is housed deep in a notch in the

  handlebar support structure, which allows, therefore,

quent, the production of vibrations.

  When, acting on the handlebar handle, the stud is placed, overcoming the force of its spring, in a high position which corresponds to pedaling without vibration, the lower structure of the handlebar, under the effect of the lower exercise spring rowing, comes into strong contact with the stud, which prevents displacement

2545727.

  of it and therefore the change of position.

  In this position, the bearing is separated from the polygonal plate and therefore the pedaling produces no vibration. When you want to make the change at

  vibration position, it is necessary to exercise prior-

  a small rowing movement on the handlebars to

  trim the handlebar support structure and the stud, this

  which allows the displacement of the latter under the ac-

  tion of the cable controlled from the handlebars.

  As can be seen in what has just been explained above, the means which create the vibration and which constitute one of the objects of the invention are based

  on the constituent and conventional elements of a bicy-

  static debt of gymnastics, and consequently,

  as a simple mechanism of high reliability and which requires little maintenance, the user has the possibility of obtaining

  a complementary vibratory exercise and to vary the exercise

  extremely simple, without having to get off the bicycle and therefore without having i

  break the rhythm of gymnastic exercise.

  The third fundamental aspect of the bicycle which constitutes the object of the invention consists in the means

  support of the respective legs of the bicycle on the ground.

  So far, static bicycles have

  of gymnastics in question, so as not to

  deteriorate the surface on which they rest and

  same time to obtain a regular support and without sliding-

  were fitted with elements in their support legs

  in the form of caps or blocks of rubber or material

  similar synthetic material which, adapting perfectly and elastically to the ground and to the small efforts of these

  gymnastic apparatus, constituted ade-

quats to their function.

  However, currently, in 254572 x gymnastics bicycles, in addition to the classic pedaling function, the vibration movement mentioned above can be obtained.

  which facilitates muscle relaxation in addition to other ca-

  similar advantageous characteristics, and therefore conventional supports are ineffective because they establish a too rigid connection between the bicycle and the gymnastic apparatus and the support surface, a rigidity which has two main defects:

  Reduced efficiency of the vibrating movement

  roof, because, since the bicycle constitutes an element practically fixed on the ground, only vibrate

  certain parts of the body, for example the arms.

  A vibration transmission to the floor, which produces in the frame of the apartments a drum effect

  extremely unpleasant, which creates noises and vibrations

tions.

  Under these conditions, taking into account these

  pects and disadvantages of the bicycle in question, there was a change in the support means, which

  are made up in such a way that the entire bicy-

  Glette is supported in a floating position which acts as a conventional support, in the case of relatively static exercises, but which constitutes an adequate support system

  in the event of vibration generating exercise, because without

  prevail the full support of the bicycle on the ground, it can vibrate as a whole, which allows to obtain a more advantageous effect on the body of the user thanks to the vibration of its whole and which allows 'get

  also a total absorption of unpleasant noises.

  In this sense, the support means in question are constituted, each of them, by two bowls located face to face which penetrate telescopically into each other and between which an elastic element has been provided, such as for example a perfectly centered coil spring To avoid disassembly of this unit, the lower cup

2545727.

  has a central rod which, penetrating a central hole

  tral on the other, allows the attachment of the assembly which is

  retained by a stud or similar element.

  The lower bearing surface of the lower bowl

  rieure has the shape of a large diameter disc which constitutes a contact stop between the two bowls and has a sufficient surface for the pressure per unit area to be minimal on the ground. there is provided below this disc an EIA-emnt of rubber, felt or a material capable of absorbing energy, which constitutes a damping comp; rs Ire and which avoids the deterioration of the delicate surfaces of support as for example floors, etc. Therefore, and taking co I 2 pt D aspects

  fundamentals of the bicycle which J constitutes the ob-

  jet of the invention, the latter has substantial advantages over apparatus or bicycles of this type, since, firstly, this bicycle is provided with an extremely static and advantageous frame, and moreover comprises a system or means of vibration of the user's body which, as indicated, are extremely

  advantageous compared to traditional vibra-

  tion, and further comprise elastic support means which make it possible to apply to the whole body of the user

a more intense vibration.

  Other features and advantages of the

  vention will be better understood on reading the description

  which will follow from an exemplary embodiment and with reference to the accompanying drawings, in which: FIG. 1 represents a perspective view

  of the part that can be considered as chassis or

  dre of the gymnastic bicycle of the invention; 2 shows a plan view of the upper part of the chassis or the frame shown in the previous figure;

2545727.

  Figure 3 shows an elevational view la-

  of the general structure of the gymnasium bicycle

  tick object of the invention, devoid of the handlebars and the corresponding saddle, although endowed with all the other elements which characterize it; FIG. 4 represents a partial view of the general structure of the bicycle which makes it possible to observe

  the detail of the means which constitute the vibrating mechanism

  roof; in this figure, the mechanism or the means in question are shown in the inactive position, that is to say in the position in which it is possible to carry out pedaling but not the vibration; FIG. 5 represents a view similar to the

  previous in which the means which constitute the

  vibratory mechanisms are in active position, the bearing being shown in contact with the polygonal plate so that during pedaling occurs the vibration; FIG. 6 shows a partial side elevation view of the structure of the bicycle in which an alternative embodiment of the means which constitute the vibratory mechanism has been provided; FIG. 7 represents a perspective view of the structure fixed to the general frame of the bicycle,

  and on which is located the stud with the corresponding spring-

  laying, stud which, depending on the position it occupies

  eg, allows or does not activate the mechanism or the vibration means; Figure 8 shows a sectional view of one of the support means connected to the corresponding tab in the rest position; FIG. 9 represents a view similar to the previous one in which the support means are in position

  active, i.e. they support the weight of the user

  sator when mounted on the bicycle.

  In the figures described above and with reference to

2545727.

  rant more precisely and firstly in Figures 1 and 2, we can see the chassis or general frame of the bicycle which is formed from an elongated piece 1

  whose cross section has the shape of an ellip-

  balance and which at one of its ends has a narrower zone 2 which creates an appendage of cross section in the shape of an inverted "U", while the piece in question 1, of curved profile, ends at its end opposite to the

  narrower zone 2 by a semi-circular cross

  area 3 to which the corresponding support leg will be fixed

  dante 4 Near the cross-member 3 of semi-circular shape

  laire, there was provided in room 1 a longitu-

  dinal 5 provided on one of its sides with a series of notches 6 in which it is possible to place and maintain the corresponding lever 7 (FIG. 3), by means of which

  can adjust pedaling resistance.

  In the end area of room 1 in the-

  which is formed the narrower part 2 and on each side thereof are arranged two tubular elements 8

  in solidarity with this narrower part which, by accompanying it

  gnant, proiongent to another transverse part of semicircular shape 3 similar to the part described above and on which is also fixed the other tab

support 4 of the bicycle.

  From the narrower end 2 of the part 1 emerges the tube 9 which, at its upper end, supports the traditional handlebar, while from an approximately central area, offset slightly towards the rear part of this part 1, emerges another tube 10 which, at its upper end, has a conical shape 11 terminated by a cylindrical appendage 12 provided

  notches 13 for fixing the saddle in question.

  It should be said that both the handlebar support tube 9

  that the saddle support tube 10 are provided with the

  clinching-corresponding allowing to obtain a set

  perfectly convenient for the user.

  In FIGS. 3 to 7 inclusive, which represent the mechanism or the means generating vibration, it can be seen how, integral with the chassis or the frame, is internally disposed an internal structure 14 in the-

  what is a pair of vertical plates 15 (fi-

  gure 7) which each have an orifice 16, the latter

  niers being located face to face to allow the passage of the axis of the pedals 17, on which is fixed a plate

  polygonal 18 which essentially constitutes the general element

vibration generator.

  On the other hand, the handlebar support tube 9 is extended downwards by an elongated part 19

  articulated in 20 on the structure 14 fixed on the general frame

  bicycle, which means that the handlebars and

  sequent its extension of elongated form 19 can topple over

  relative to the articulation point 20.

  Between the lower end of the elongated extension 19 and the lower end of the plates 15 is mounted a helical spring 21 which is disposed completely horizontally as shown in Figure 3, which allows to adjust, by means of the lever 7, the voltage

  of this spring 21 and therefore the resistance to pedaling.

  The spring 21 maintains by its own force the tube 9 of the handlebar in the normal position shown in

  Figures 3 and -4, but however the elasticity of this res-

  sort 21 allows the rotation or tilting of the tube 9 of

  handlebar support around its articulation 20 for

  put to perform rowing exercises.

  Therefore, when the mechanisms of bi-

  cyclette are in the position shown in Figures 3 and 4, it is possible to achieve, first, a

  normal pedaling, and secondly it is also possible

  rowing exercises using the rocker

  Lement commented above, of the handlebar support tube 9.

2545727.

  The elongated extension 19 of the tube 9

  of the handlebar comprises, in the same plane as the poly-

  gonal 18, -a bearing 22 capable of coming into contact with the periphery of this polygonal plate 18, so that when this contact occurs the pedaling gives rise to the vibration of the structure or of the tubular support 9 of the

  handlebars as well as the vibration of the user himself.

  In order for this vibration movement to occur, it was born

  necessary, as was said earlier, that the bearing 22 comes into contact with the periphery of the polygonal plate 18, as in the representation of FIG. 5, while in FIGS. 3 and 4, the contact in question has no not due to the interposition of a stud 23 located transversely between the two elongated openings 24 provided for this purpose in the plates 135, as can be

  see in figure 7, so that the displacement of the gou-

  jon 23 takes place from the handlebars, opposing the

  that of a spring 25 disposed between the latter and a cross member 26 which tends to cause the stud 23 to occupy the lower position inside the elongated openings 24 The spring 25 is supported between the stud 23 and the cross member 26, of the makes it coaxial with the corresponding part of the pull cable 27 actuated from the handlebars as it

was said above.

  Instead of a direct fixing of the cable 27 on the stud 23, FIG. 6 represents a variant of greater precision of adjustment, in which the end of the cable 27 is fixed to the end of a lever of the first kind 38 which has a bent shape and which is articulated centrally at point 29 on the structure 14, while, at its other end, the lever 28 in question has a fork 30 which retains the stud with some play

  23 and tends to move it in the elongated openings

  24, overcoming the force of the spring 31 fixed between the

  lever 28 and the fixed structure 14 on the frame or general frame

2545727.

  ral This solution makes it possible to tension the cable 27 so

  simpler when the user of the bicycle demands it.

  In any case, both when the cable 27 is connected to the lever 28 and when it is directly connected to the stud 23, in the position which corresponds to the absence of vibration, the stud 23 is held without any possibility of displacement by the pressure exerted by the elongated extension 19 subjected to the tension of the spring 21, the stud in question 23 being retained between the edge of the extension 19 and the respective edges of the openings of

  elongated shape 24 in which the guide is housed and guided

  jon 23, as can be seen in Figures 3 and 4 In this way, the stud 23 constitutes a stop which prevents contact between the bearing 22 and the polygonal plate 18, and therefore, when the user rotates

  the pedals 17, a normal pedaling exercise is obtained.

  When the bicycle is placed in the posi-

  tion of normal pedaling, which corresponds to FIGS. 3, 4 and 6, if one wishes to switch to the vibration position, it is first of all advisable to exercise, in the direction indicated by the arrow 31 in FIG. traction on the handlebars, to place it in the position shown in FIG. 4, to release the stud 23 so that it can move. When the stud 23 has been released from the pressure exerted on it by the elongated extension 19,

  being connected to the corresponding handle of the handlebar, the

  jon 23, under the effect of spring 25, will descend to occupy

  the lower position inside the opening of the

  lie down 24 At this time, if you stop acting on the handlebars, so that the latter recovers its position

  normal under the effect of spring 21, bearing 22 enters

  ra in contact with the polygonal plate 18, and consequently

  that pedaling will give rise to the vibration of the whole.

  Figure 5 shows the position described more

2545727.

  top and we can see how the elongated extension 19 of the tube 9 of the handlebar is provided with a large notch 32 in which the stud 23 is blocked to allow the establishment of direct contact between the bearing 22 and the polygonal plate 18, contact which will be maintained due to the action of the spring 21 which will exert a traction on the lower part of the extension 19 to maintain, as was said above, the blocking of the stud 23 in the notch 32 A To return to the normal position, it will suffice

  to act again on cable 27, after having switched over

  ler the handlebar tube and ensure that the stud 23 occupies the position shown in Figures 3, 4 and 6, in which we can see how the polygonal plate

  18 has ceased to be in contact with the bearing 22.

  The following is the description of the support means

  of the bicycle on the ground, these means being constituted by two bowls 33 and 34 located one inside the other in a telescopic manner The bowl 33 is arranged in reverse position and it is fixed by its base on the corresponding end of the lug 4, while the bowl 34 is the lower bowl in which the bowl 33 is housed. Between the two bowls, an internal spring 35 has been provided which constitutes an element

elastic energy absorption.

  The bottom e of the lower bowl 34 forms a disc 36 on which is fixed a block 37 of rubber and similar material which constitutes the non-slip means

and shock absorber on the ground -

  From the center of the disc 36 which constitutes the base of the bowl 34 emerges upward a rod 38 which crosses the center of the bottom or of the upper base of the bowl 33, with the particularity that this rod 38, near its free end, has a perforation 39 of reduced diameter in which can be accommodated a stud or similar element intended to constitute

  a means of limiting the stroke of the spring 35, acting

  thus being a device intended to maintain the whole

  seems to be in the rest position, because the leg corresponds

  dante 4 has for this purpose an opening 40 which allows a

  displacement of the bowl 33 up and down.

  In this way, when the legs 4 are subjected

  at a charge that the user is mounted on the bi-

  cyclette, the spring 35 is compressed and therefore the

  bicycle is in an intermediate position and afloat

  aunt in an elastic manner without the support transmitting

  brations on the ground, but nevertheless allowing the vibration of the whole bicycle and therefore of the whole body of the user, which gives rise to an advantageous effect on

  the entire body of the user.

  It should be added that the bottom of the lower bowl 34 may include a small ring 41 for the

  centering of the spring 35, while the disc 36 which constitutes

  titue the bottom in question exceeds relative to the perimeter of the bowl 34 to thus constitute a lower stop

  lowering bowl 33.

  Finally, it should be added that the part

  front of the frame first described defines a suf-

  fisant to mount a flywheel 42 for the pedaling exercise, and, due to the special configuration of the frame, the flywheel 42 protrudes from it and is in front of the general structure of the bicycle, which allows the mass of this steering wheel 42 to act as a counterweight during the rowing exercise which can be carried out as has been commented on in this description. Of course, various modifications can be made by those skilled in the art to the devices which have just been described only by way of nonlimiting examples.

  without departing from the scope of the invention.
