DESCRIPTION
FIELD OF THE INVENTION
[00011 The present invention relates to an exercise bicycle, that is, a bicycle of the type used in gyms or private homes, allowing similar use and exercise as a conventional road bicycle.
BACKGROUND OF THE INVENTION
[OO1A] An exercise bicycle with an arched frame, crossbars, pedal shaft, mast and seat is disclosed in FR-A-2032043. An exercise bicycle with the mast, seat, and handlebar connected is disclosed in FR-A-2624751.
[0002] The object of the invention is to obtain an exercise bicycle which closely approximates the functional simulation of a conventional road bicycle.
SUMMARY OF THE INVENTION
100031 To achieve this, more specifically, the bicycle consists of a frame made from two tubes joined at their ends, which form an angle which is placed considerably higher than the ends, on which ends transverse support tubes are placed, on the end of which are stands or suction cups for support to the floor, while inside the aforementioned angle is a crossbeam, formed from two lateral flat bars, between which is placed the pedal shaft with appropriate ball bearings and with the classical drive pulley, to which any available variable braking mechanism will be connected in order to control the effort required on the pedals, this crossbeam also being stiffened by another two ascending flat bars which also emerge from the support bushings for the aforementioned ball bearings, and which reach the anterior longitudinal arm of the frame, extending to the other side as a tubular mast designed to place the traditional seat on its end so that it's position can be adjusted, and meeting a crossbeam near its top end which extends forward, thus stiffening the mast, together with a reinforcement angular bracket, also with a tubular structure, inside which [003A] According to an aspect of the present invention, there is provided an exercise bicycle, comprising:
- a frame which at the bottom ends in support crossbars;
- a bridge structure connected to the frame;
- a stand for the pedal shaft supported by said bridge structure;
la - a mast, to which the seat is directly connected, rising from said frame, said mast being connected near its upper end to an anterior-upper crossbar which extends forward;
wherein the frame is made out of an anterior tube and a posterior tube welded together at an end, defining an angle which is located on the vertical, longitudinal and mid plane of the bicycle;
an ann, associated to a support of a handlebar, is telescopically attached to the anterior-upper crossbar, and the frame is joined to the support crossbars so that it may oscillate side to side, in order for which between tubes of said frame and support crossbars are placed corresponding pairs of lateral shock absorbers, in which case the support crossbars end in suction cups for adherence to the floor.
is an arm which ends in a double handlebar which telescoping inside the bracket and which may be locked in any position, so that the handlebar can be adjusted in many ways.
100041 The main tubes of the frame can be connected to the leg-like crossbars rigidly or jointedly, in which latter case between each tube and the corresponding crossbar are placed a pair of lateral shock absorbers against which it is possible to swing the frame side to side, so as to simulate the classical movement of a road bicycle as the body rises from the seat as when climbing hills or sprinting. In this case the stands must be the aforementioned suction cups to minimise the risk of the bicycle falling sideways.
[00051 It only remains to point out that two covers forming a cowling will be affixed to the sides, hiding the moving parts of the bicycle and the bridge support structure which supports them for cosmetic reasons, for this same reason the mast and upper crossbar shall also be hidden by similar lateral covers.

PREFERRED EMBODIMENT OF THE INVENTION
[0016] In view of these figures, it can be seen how the exercise bicycle proposed is structured by a frame on which two longitudinal tubes (1) and (2) are placed along the vertical, longitudinal and horizontal plane of the bicycle, which are welded to each other at one of the ends (3) forming a slightly obtuse angle, of unequal arms, slightly arched and concave from the bottom, these tubes (1) and (2) ending in their free lower ends in respective grooved baseplates (4), for coupling to the corresponding support crossbars (5) which form the bicycle stand on the floor, being of a sufficient length to make the bicycle stable.
[0017] Both tubes (1) and (2) and support crossbars (5) may be cylindrical, as shown in the figures, or have any other cross section.
[0018] In any case, from tube (2) of the frame relatively near its posterior end begins a mast (6), slightly inclined backwards, also tubular, intended to receive on its upper end the traditional seat (7), which telescopes and can be adjusted in position, and joined to this mast (6), an anterior-upper crossbar (8) which extends forward horizontally also tubular and inside which telescopes an arm (9) which can be set in any position by conventional clamping devices (10), and to which arm (9) is joined support (11) of the handlebar, which will be dealt with below.
[0019] Anterior-upper crossbar (8) and the mast (6) are stiffened by a reinforcement bracket (12) of angular construction, joined to its anterior-lower generatrix, and also joined by its lower end to the anterior tube of the frame.
[0020] Under tube (2) and as a lower extension of mast (6) are a pair of parallel flat bars (13), which are welded on their lower ends to corresponding bushings (14), to which in tuin are welded another two flat bars (15) extending forward horizontally, and another pair of flat bars (16) extending backwards, and which respectively are joined to anterior tube (2) and posterior tube (1), forming a vertically stiffened transversal bridge in the heart of the frame, which ensures the correct functional rigidity for said bushings (14) in which are housed ball bearings (17) for the pedal shaft (18) on which the drive pulley (19) is mounted, against which will act pedals (20) by the respective shafts (21).
[0021] The structure described corresponds to a rigid bicycle, in which frame (1-2) is not able to rock sideways, and in which support crossbars (5) acting as stands end in decorative elements (22) seen in figure 9, but there also exists the option of frame (1-2) being able to swing side to side as in figures 4 to 8, in which case the grooved baseplates (4) are eliminated and replaced by either joints (23) between triangular flat bars (24) and (25) as shown in figure 5, or by elastic elements (26) as shown in figure 6.
[0022] In any case support crossbars (5) will end in suction cups (27) instead of stands (22), in order to improve the stability of the bicycle by the grip of said suction cups (27) to the floor, and also in any case each joint (23) or (26) will be connected to a pair of lateral shock absorbers (28), jointed at their ends (29) and (30), respectively, to frame (1-2) or support crossbar (5), as shown in all of figures 5, 6 and 8.
[0023] These shock absorbers (28) are meant to act only when the frame rocks against them, for which the upper end (29) of each moves in a groove (31) of frame tube (1-2) itself, which allows said end (29) to move down along tube (1-2) when it swings in the opposite direction, as shown in figure 8, without resulting in an excessive extension of the shock absorber.
[0024] Returning to the bicycle handlebar, attached to the aforementioned support (11) are two different handlebars, to be used indifferently, a U-shaped handlebar (32) on whose lateral arms are segments which first descend and finally bend forward, and an annular handlebar (33) which is also basically U-shaped and whose side ends are attached to the middle section of the first handlebar (32), said side ends converging from the middle to the far ends, as well as being bent, and having relatively near their start short auxiliary and lateral flat bars (34) on which are placed corresponding support pads (35) for the user's forearms.
[0025] The structure described is complemented by two symmetrical covers (36) and (37) which are attached to the top of tubes (1) and (2) of the frame, thus creating side panels which cover the bridge structure which supports the pedal shaft, making a cosmetic cowling out of which remain only shafts (21) and pedals (20), as seen in figure 9, while the other two symmetrical lateral covers (38) and (39) cover mast (6), anterior-upper crossbar (8) and reinforcement bracket (12) completing the lower cowling and giving the bicycle a pleasing finish.
[0026] It is not considered necessary to extend this description further for any expert in the matter to understand the scope of the invention and the advantages derived thereof.
[0027] The materials, shape, size and arrangement of the elements will be subject to variations as long as this does not cause an alteration of the essence of the invention.
[0028] The terms of this memory must always be taken in a wide and non limiting sense.
[0029] The described bicycle shall be provided with means to regulate the effort required to act on the pedals, these means not being represented as their constitution is known in itself 5 and in this type of bicycle.
[0014] Figure 8.- Shows a posterior elevation enlargement of the set shown in the previous figure, in the same position.
[0015] Figure 9.- Shows, finally, a general perspective of the finished bicycle, that is, with the handlebar and cosmetic covers.
