Abstract
A treadmill comprises a frame (10) having a base suitable to receive a support deck (20) located between a front roller and a rear roller, and an endless belt (30) wound around the front and rear rollers with the support deck (20) arranged between an upper portion and a lower portion of the endless belt (30), as well as a device (40) for detecting the temperature due to the heat generated by the friction between the endless belt (30) and the support deck (20), the device (40) being connected to a control unit that activates signalling means to show the user that a preset temperature threshold has been reached, hi this way, the user knows when it is necessary to lubricate the support deck without having to remember to do it at preset intervals or having to rely on imprecise indirect signals calculated on the basis of the operating time or of the total distance covered.
Description
'TREADMILL WITH DEVICE FOR SIGNALLING THE NEED TO LUBRICATE THE SUPPORT DECK'
FIELD OF THE INVENTION The present invention relates to a treadmill with a device for signalling the need to lubricate the support deck, and in particular with a device that employs a temperature probe to detect the friction between the support deck and the endless belt.
BACKGROUND OF THE INVENTION A conventional treadmill generally includes a rectangular frame, two transverse rollers supported on the frame, a support deck located between the two rollers and an endless belt wound around the two rollers and driven by the user's push or more preferably by a driving device including a motor suitable to drive the front roller. The user walks on the endless belt and the support deck exerts its supporting function, with the endless belt sliding thereon with a certain friction particularly at the point where the user's foot presses the endless belt onto the support deck.
To prevent damage to the endless belt it is therefore necessary to provide a periodical lubrication of the support deck that in top-of-the-line treadmills is even automatic, i.e. there is provided a device that keeps the support deck constantly lubricated whereby the treadmill is "self-lubricating".
Such a device, however, is expensive and therefore restricted to top-of-the- line models, whereas in most treadmills there is not provided any signalling of the need to lubricate the support deck or said signalling is only indirect, since it is calculated on the basis of the operating time or of the total distance covered.
In the first instance it is obvious that the correct operation of the treadmill depends on the possibility that the user remembers to carry out the lubrication at the preset intervals, but also the indirect signalling is risky and imprecise because the consumption of lubricant is affected by various factors that are not taken into consideration, such as the speed of the endless belt, the user's weight, the more or less hot and/or dusty environment where the treadmill operates and so on.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a treadmill with a device for signalling the need to lubricate the support deck which overcomes the above- mentioned drawbacks. This object is achieved by means of a treadmill wherein said device employs a temperature probe to detect the friction between the support deck and the endless belt.
The present invention will become more evident from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig.l is a partially exploded view showing the treadmill of the present invention with the device for signalling the need to lubricate the support deck;
Fig.2 is a partial perspective see-through view showing the above- mentioned treadmill;
Fig.3 is a partial longitudinal sectional view showing the above-mentioned treadmill; and
Fig.4 is an enlarged view of a detail of the treadmill corresponding to the dotted circle of Fig.3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to said figures, there is seen that a treadmill according to the present invention conventionally comprises a frame 10 having a rectangular base and two posts extending from the front end of the base so as to be connected to a handlebar and a control panel (not shown). A support deck 20 is located within frame 10 on a plurality of cushioning pads 50, and an endless belt 30 is wound around the two front and rear rollers with the support deck 20 arranged between an upper portion and a lower portion of the endless belt 30.
The novel aspect of the present treadmill resides in the presence of a temperature detection device 40, comprising a temperature probe 41 operatively connected to the control unit of the treadmill through a wire 42. Probe 41 is
preferably arranged in a recess 21 formed in the bottom side of the support deck 20 at a substantially central position, where the user is generally located, so as to be adjacent to the region of maximum friction between the endless belt 30 and the support deck 20. By measuring the temperature due to the heat generated by the friction in that region it is possible to directly detect the amount of friction and therefore the need to lubricate the support deck 20. To this purpose, the signal of the temperature detected by probe 41 is transmitted through wire 42 to the control unit that upon reach of a preset threshold commands the activation of a visual and/or acoustic signal on the control panel, to show the user that the support deck 20 needs to be lubricated.
If the user ignores the signal and the temperature continues to rise, it is preferably provided that upon reach of a second temperature threshold the control unit stops the motor to prevent damage to the treadmill. While we have shown and described the above embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention as defined by the appended claims.
In particular, the temperature probe 41 may be of any kind and may be located even at another position, or there may be provided multiple probes. For example, in combination with or instead of probe 41 arranged in recess 21, an optical temperature sensor arranged directly inside the control panel could be used.
Claims
1. Treadmill comprising a frame (10) having a base suitable to receive a support deck (20) located between a front roller and a rear roller, as well as an endless belt (30) wound around said front and rear rollers with said support deck (20) arranged between an upper portion and a lower portion of said endless belt (30), characterized in that it further includes a device (40) for detecting the temperature due to the heat generated by the friction between the endless belt (30) and the support deck (20), said device (40) being operatively connected to a control unit of the treadmill, as well as signalling means controlled by said control unit to signal the user upon reach of a preset temperature threshold.
2. Treadmill as claimed in claim 1, characterized in that said temperature detection device (40) includes at least one temperature probe (41) connected to the control unit through a wire (42).
3. Treadmill as claimed in claim 2, characterized in that the temperature probe (41) is arranged in a recess (21) formed in the bottom side of the support deck (20).
4. Treadmill as claimed in claim 3, characterized in that the recess (21) is formed at a substantially central position of the support deck (20).
5. Treadmill as claimed in claim 1, characterized in that said temperature detection device (40) includes at least one optical temperature sensor arranged directly inside the control panel of the treadmill.
6. Treadmill as claimed in any of the preceding claims, characterized in that the endless belt (30) is driven around the front and rear rollers by a motor.
7. Treadmill as claimed in the preceding claim, characterized in that the control unit is provided with a second temperature threshold upon reach of which it stops the motor that drives the endless belt (30).
