Definitions

  • the present invention relates to a 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.
  • the object of the invention is to obtain a exercise bicycle which closely approximates the functional simulation of a conventional road bicycle.
  • 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 is an arm which ends in
  • 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.
  • the stands must be the aforementioned suction cups to minimise the risk of the bicycle falling sideways.
  • Figure 1. Shows, in a perspective sketch, the frame or basic structure of the exercise bicycle.
  • Figure 2. Shows a side elevation of the objects shown in the above figure, on which the pedal shaft and accessories have been installed.
  • Figure 3. Shows an enlarged cross section of the objects shown in the previous figure, along the A-B line of said figure.
  • Figure 4.- Shows a side elevation of the objects of figure 1, in the specific case where the structure is able to rock laterally.
  • Figure 5. Shows an enlarged posterior elevation of the objects of the previous figure, according to an embodiment in which the frame is jointed with the supports.
  • Figure 6. Shows a similar view to figure 5 but corresponding to an embodiment in which the frame is joined to the transverse supports by elastic elements.
  • Figure 7. Shows an enlargement in side elevation of the back part of the objects in figure 4, with the frame swinging side to side, allowing to see the slot which makes one shock absorber disconnected while the other supports the oscillation.
  • Figure 8.- Shows a posterior elevation enlargement of the set shown in the previous figure, in the same position.
  • Figure 9. Shows, finally, a general perspective of the finished bicycle, that is, with the handlebar and cosmetic covers.
  • 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 crossbars (5) which form the bicycle stand on the floor, being of a sufficient length to make the bicycle stable.
  • Both tubes (1) and (2) and crossbars (5) may be cylindrical, as shown in the figures, or have any other cross section.
  • 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), a bar (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.
  • 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.
  • the structure described corresponds to a rigid bicycle, in which frame (1-2) is not able to rock sideways, and in which 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.
  • 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 crossbar (5), as shown in all of figures 5, 6 and 8.
  • 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.
  • 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.
  • 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), crossbar (8) and reinforcement bracket (12) completing the lower cowling and giving the bicycle a pleasing finish.
  • 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 and in this type of bicycle.
