Description

Exercise apparatus
The invention relates to an exercise apparatus comprising a frame and a belt running around rollers at the front end and back end of said frame, a drive for said belt and ancillary equipment selected from the group comprising left and right handlebars, and a monitor for providing feedback or computer-generated information to a user.
Such an exercise apparatus is for instance known from the applicant's earlier patent NL 2 004 512 granted October 10, 2011. In this known exercise apparatus which is a dedicated bicycle trainer the combination is proposed of a treadmill belt and a bicycle with its front wheel and back wheel placed on the belt. In this known exercise apparatus the belt is provided with a first sensor at its forward end, and a second sensor at its backward end for detecting the front wheel and the back wheel of the bicycle respectively, which sensors are connected to a controller which provides steering signals to a first motor and/or a second motor of the belt for controlling said belt's speed, respectively said belt's slope. The controller is further arranged to effect that the belt's speed and/or the belt's slope is increased upon the first sensor detecting the front wheel of the bicycle. In another aspect the controller is arranged to effect that the belt's speed and/or the belt's slope is decreased upon the second sensor detecting the back wheel of the bicycle .
Another prior art exercise apparatus embodied as a bicycle trainer is known from W02005/035072. This apparatus is embodied with a frame and a treadmill belt and in addition a sensor which produces a signal representative of the user's position relative to at least one point on the frame. A belt rotation assembly turns the belt with a speed related to the signal. In one preferred embodiment the speed of the belt is inversely proportional to the distance between the user and the front of the treadmill.
Yet another prior, art exercise apparatus is known from FR-A-1.565.616,. This apparatus is a dedicated running exercise apparatus, comprising a frame and a belt running around rollers at the front end and back end of said frame as well as over rollers between said front end and back end rollers, and a drive for said belt. This publication is from 1968 and is very basic without handlebars on the sides and without any electronic information devices such as a monitor.
Generally speaking the known exercise apparatuses, be it bicycle trainers or running trainers are construed sturdy, making them hard to handle.
Further the requirements imposed on bicycle trainers and running trainers are guite different. Bicycle trainers have a need to quickly adjust to slight differences in speed of the cyclist. Running trainers however have to set a prescribed pace for the runner. It is for this reason that running trainers are conventionally embodied with a flywheel. A disadvantage is however that this adds to the weight of the running trainer.
It is an object of the invention to address one or more of these problems of the prior art exercise apparatuses and to propose an alternative for those existing apparatuses.
The exercise apparatus of the invention has the features of one or more of the appended claims.·
According to a first aspect of the invention the frame comprises a sandwich panel, which panel is embodied with a plastic core sandwiched between aluminium panels to provide a rigid and lightweight construction. This makes handling of the exercise apparatus very easy. Moreover the construction of the exercise apparatus of the invention is more cost-efficient.
Suitably the sandwich panel is supported by aluminium profiles on the left and right side of said sandwich panel.
To avoid any conflict in driving speed or driving torque of the applied drive(s) with reference to the driven belt, it is preferred that at least one of the rollers is an idle roller.
In another aspect of the invention which can be ap- plied independent from the above mentioned features regarding the construction of the frame, it is beneficial that at least one of the rollers is provided with a drive. This results in a very compact construction and also restricts weight of the complete apparatus .
In one preferred embodiment at least one of the rollers is provided with a direct drive. A direct drive is very suitable to embody various control strategies with corresponding effect on the control speed of the drive for the belt. This enables that an easy switchover is possible between application of the exercise apparatus as running exercise apparatus or as bicycle trainer. A suitable construction of the exercise apparatus is arranged such that at least one of the rollers is rotatably mounted on an axle, wherein on said axle and within the roller a magnetic coil or coils are provided that form part of the drive of said roller. This construction is indeed very suitable to restrict both weight and size of the exercise apparatus .
It is then further preferred that at the rollers inner circumference one or more stationary mounted magnetic elements are provided forming part of the drive of said roller .
In another aspect of the invention the drive is preferably connected to control equipment which is adjustable between a slow response speed and a quick response speed with reference to each other, wherein the slow response speed of the control equipment corresponds to use of the apparatus for running exercises, and the quick response speed of the control equipment corresponds to use of the apparatus for bicycle training.
In one preferred embodiment of the exercise apparatus of the invention comprises a sensor for monitoring a side of the belt, wherein the sensor is connected to control equipment driving at least one of the rollers so- as to keep said side of the belt positioned at a predefined position with reference to the sensor. This secures reliable operation of the exercise apparatus without danger that the belt will runoff the rollers.
It is further preferable that in use the monitor provides user information depending on the speed and/or slope of the running belt relative to a desirable position of the user on the belt. .
The invention will hereinafter be further elucidated with reference to the drawing of an exemplary embodiment of an exercise apparatus according to the invention that is not limiting as to the appended claims. - In the drawing: -figure 1 shows an exercise apparatus according to the invention with a bicycle provided on the belt of the exercise' apparatus; -figure 2 shows a longitudinal section of the frame forming part of the exercise apparatus shown in figure 1; -figures 3A, 3B, 3C, 3D and 3E show an isometric view, a top view, a side view, a frontal view and a detailed view of the frame shown in figure 2, however without rollers at its front and back end; -figures 4A, 4B, 4C and 4D show an isometric view, a frontal view, a side view, and a sectional view of it driven roller used at the front end or back end of the frame that is shown in figures 3A, 3B, 3C, 3D and 3E.
Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
Making first reference to figure 1 an exercise apparatus 1 is shown comprising a frame 2 and a belt 3 running around rollers 4, 5 at the front end 6 and back end 7 of said frame 2. At least one of the rollers, for instance the back end roller 4 is an idle roller, and at least one of the rollers, for instance the front end roller 5, is provided with a drive. This is however not essential; it can also be the other way around. The details of the preferably applied drive for the belt 3 will be further detailed in the remainder of this specification making reference to figure 4A - D.
Continuing with figure 1 the exercise apparatus 1 preferably is provided with ancillary equipment selected from the group comprising left and right handlebars 8, 9, and a monitor 10 for providing feedback or computer-generated information to a user. Computer-generated information can comprise selected outdoor tracks such as known classical trials as the Luik-Bastenaken-Luik trial or classical mountain trials such as on the Mont Ventoux in France. The user that applies the exercise apparatus 1 as a bicycle trainer then gets images relating to the said outdoor trials. It is also possible to include competitor information of other users through the Internet that is or are doing the same trial. The said feedback information may relate to speed and power consumption by the user, or heart rate and other physical data. This feedback information may be integrated with the computergenerated information.· .
With reference now to figure 2 and in particular figures 3A - 3E it is shown that the frame 2 comprises a sandwich panel 11 and that the sandwich panel 11 is supported by aluminium profiles 15, 16 on the left and right side of said sandwich panel 11. Figure 3E shows in detail the construction of the profile 15 supporting the sandwich panel 11, from which it is clear that the panel 11 is embodied with a plastic core 12 which is made of polyurethane or another suitable plastic material, which is sandwiched between aluminium panels 13, 14 to provide a rigid and lightweight construction .
Turning now to figures 4A - 4D a roller assembly 25 is shown that is provided with a drive. Usually this is the front end roller 5 shown in figure 1. The drive is preferably a direct drive and figure 4D shows that the roller 5 of the roller assembly 25 is rotatably mounted on an axle 17. The axle 17 is fixedly mounted in a suspension 21, 22 that is used for mounting the roller assembly 25 to the frame 2. The suspension 21, 22 is provided with bearings 23, 24 for the roller 5 making its rotation possible with respect to the fixedly mounted axle 17. On said axle 17 and within the roller 5, a magnetic coil or coils 18 are provided that form a constituent part of the drive of said roller 5. Further at the rollers 5 inner circumference 19 one or more stationary mounted magnetic elements 20 are provided also forming con stituent parts of the drive of said roller 5. By energizing the coils 18 a magnetic field is generated that cooperates with the magnetic elements 20 at the inner circumference 19 of the roller 5 to provide a driving force to said roller 5 with respect to the fixed axle 17 that makes it rotate in its bearings 23, 24.
Turning now again to figure 1 it is clear that the belt 3 that is guided along the driven roller 5 at the front end 6 of the frame 2 and along the idle roller 4 at the back end 7 of the frame 2, will move in accordance with the rotation of the driven roller 5.
Figure 1 further shows control equipment 25 that is connected to.the drive of the driven roller 5. This control equipment 25 is adjustable between a slow response' speed and a quick response speed with reference to each other, wherein the slow response speed of the control equipment 25 corresponds to use of the exercise apparatus 1 for running exercises, and the quick response speed of the control equipment corresponds to use of the exercise apparatus 1 for bicycle training.
Preferably the apparatus 1 comprises a sensor for monitoring a side of the belt 3, wherein the sensor is connected to control equipment 25 driving at least one of the rollers 4, 5 so as to keep said side of the belt 3 positioned at a predefined position with reference to the sensor. This is not further shown in the figures but is clear for the artisan without further elucidation with reference to a drawing.
Finally it is remarked that in use the monitor 10 may provide user information depending on the speed and/or slope of the running belt 3 relative to a desirable position of the user on the belt.
Although the invention has been discussed in the foregoing with reference to an exemplary embodiment of the apparatus of the invention, the invention is not restricted to this particular embodiment which can be varied in many ways without departing from the gist of the invention. The discussed exemplary embodiment shall therefore not be used to construe the appended claims strictly in accordance therewith. On the contrary the embodiment is merely intended to explain the wording of the appended claims without intent to limit the claims to this exemplary embodiment. The scope of protection of the invention shall therefore be construed in accordance with the appended claims only, wherein a possible ambiguity in the wording of the claims shall be resolved using this exemplary embodiment.
