Abstract
A folding-up mechanism for an electric treadmill having a single lifting motor for adjusting a platform frame to an inclined and upright position with a handrail frame moved to a storage position. The lifting motor and a drive screw are interposed between two base frames. The drive screw is screwed in a slip pipe with female thread. An intermediate tube is pivotally coupled to a rear end of the slip pipe with a front crossbar and a handrail frame coupled to the opposing end of the intermediate tube. One end of the platform frame is pivotally attached to an upright bar of the base frames while a bottom side of the platform frame is pivotally coupled to a telescopic tube, a pull rod, and a push rod that are in turn coupled to the slip pipe, the intermediate tube, and the handrail frame so that the slip pipe is movable to and fro when the lifting motor is activated to impart an in-place rotation to the drive screw, thereby achieving the expected effects.
Description
- This application is a continuation-in-part of U.S. patent application of Ser. No. 11/123,159 filed May 6, 2005.
- 1. Fields of the Invention
- The invention relates to a folding-up mechanism for an electric treadmill, and more particularly, to a folding-up mechanism having a single lifting motor for adjusting a platform frame to an inclined and upright position with a handrail frame moved to a storage position.
- 2. Description of the Related Art
- A tilting mechanism of a conventional treadmill is used to adjust the supported angle of a main frame relative to a base frame for creating a certain walking slope. Meanwhile, a fold-up mechanism is used to fold-up the main frame in a storage position for reducing the space occupied by the treadmill. Generally speaking, these can be classified into a manual and an automatic type. The present invention is an improvement of the above-mentioned mechanisms.
- U.S. Pat. No. 5,733,228 teaches a mechanism with a lifting motor, pull cable, pulley wheels and return springs to fold-up a main frame of a treadmill between two handrails. Therefore, the main frame can be lifted in a tilt and a fold-up position. Although this prior art has its original design, the mechanism requires complicated and miscellaneous components. In addition, the pull cable and the return springs are subject to fatigue and slack. This is regarded as drawbacks of this prior art.
- Another prior art U.S. Pat. No. 6,325,745 teaches a treadmill with its main frame pivotally coupled to a slide groove of a base. Meanwhile, a lifting motor pushes downwardly a supporting rod pivotally attached to the main frame. In this way, the main frame is swivelable in the slide groove to be lifted in a storage position. However, this apparatus doesn't have the function to bring the main frame in a tilt position. Besides, the lifting motor applied its driving force to only one end of the main frame so that the arm of force is evidently mechanically too short. Especially, the lifting motor is movable with the lifting action, and the lifting motor bears all loading created by the main frame. So, the lifting motor is subject to overload that would cause damage to the lifting motor.
- A further prior art U.S. Pat. No. 6,015,368 teaches a treadmill with a longer spindle and sleeve to support a rear supporting rod at a bottom end behind a main frame over a long distance to fold-up the main frame. Also, this prior art doesn't have the function of tilting the main frame. Moreover, a lifting motor has to be movable with the lifting action. Thus, it has the same disadvantages as U.S. Pat. No. 6,325,745.
- Thus, based on the above-mentioned considerations, the designer employs a flat lifting motor in cooperation with a drive screw, a slip pipe, an intermediate tube, a telescopic tube, a pull rod, a push rod, and a handrail frame to allow a platform frame to swivel on a pivotal point of an upright bar for adjusting the platform frame to an inclined and upright position with the handrail frame moved to a storage position. In this way, the lifting motor can complete the lifting action with less torque output so that the service life of the lifting motor can be extended. Moreover, the supporting force can be optimally controlled. This is the primary object of the invention.
- The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
-
FIG. 1 is a perspective view of a preferred embodiment of the invention; -
FIG. 2 is an axially cutaway view of the preferred embodiment of the invention in accordance withFIG. 1 ; and -
FIG. 3 is an axially cutaway view of the preferred embodiment of the invention in accordance withFIG. 1 , showing the action to bring a platform frame in an inclined position; -
FIG. 4 is an axially cutaway view of the preferred embodiment of the invention in accordance withFIG. 1 , showing the action to lift the platform frame toward an upright position; and -
FIG. 5 is an axially cutaway view of the preferred embodiment of the invention in an upright position with a handrail frame to be moved in a storage position. - Referring to
FIGS. 1 and 2 , a treadmill in accordance with the invention includes: - a
platform frame 10 having arear roller 13 driven by amotor 11 through adriving belt 12, therear roller 13 being active in cooperation with afront roller 14 for an in-place rotation of acontinuous belt 15; - two
base frames 20 having anupright bar 21 extending from a central point thereof, theplatform frame 10 being pivotally connected to theupright bars 21; - a lifting
motor 30 for driving adrive screw 31 to undergo an in-place rotation; - a
slip pipe 40 having a female threadedhole 41 for receiving thedrive screw 31; - an
intermediate tube 50 pivotally disposed at a distal end of theslip pipe 40, afront crossbar 51 being connected at an opposing end of theintermediate tube 50, ahandrail frame 52 extending upwardly from a rear end of theintermediate tube 50, anelectronic console 53 being fitted atop thehandrail frame 52; - a
telescopic tube 60 with both ends thereof pivotally coupled to afirst crossbar 16 at a bottom side of theplatform frame 10 and to a top side of the rear end of theslip pipe 40, respectively; - a
pull rod 70 with both ends thereof pivotally coupled to asecond crossbar 17 at a bottom side of theplatform frame 10 and to a middle portion of theintermediate tube 50, respectively; and - a
push rod 90 with both ends thereof pivotally coupled to the read end of theslip pipe 40 and to a bottom end of thehandrail frame 52, respectively. - Referring to
FIGS. 2 through 5 , the action of the aforementioned configuration is shown. Theslip pipe 40 is moved to and fro when thelifting motor 30 is activated to impart an in-place rotation to thedrive screw 31. As shown in FIGS. 2 und 3, theplatform frame 10 is adjusted to an inclined position. At this point, theplatform frame 10 is swiveled on a pivotal point A of theupright bar 21 for simulating an uphill or a flat surface. As shown in FIGS. 4 und 5, theplatform frame 10 is adjusted to an upright storage position. Referring toFIG. 3 , asleeve 61 reaches the end of thetelescopic tube 60. When theslip pipe 40 continues to move toward thelifting motor 30, thetelescopic tube 60 will gradually lift theplatform frame 10 due to the connection relationship. Since theintermediate tube 50 and theslip pipe 40 are pivotally coupled, theintermediate tube 50 can be swiveled on a pivotal point B to be lifted by thepull rod 70 until theplatform frame 10 is moved to an upright position. When theintermediate tube 50 is moved upwardly, the distance between the pivotal point C and the pivotal point B is reduced. Under the condition that the length of thepush rod 90 remains unchanged, thehandrail frame 52 will be moved toward theplatform frame 10. - In order to bring the
main frame 10 in operational position, theslide tube 40 is extended by the liftingmotor 30 in a reverse drive direction. - In light of the safety, a
protection cover 22 is accurately extended between both inverted T-bases 20 to prevent the internal transmission units from direct exposure to the outside. - In order to separate the tilting action from the fold-up action as well as to prevent the lifting
motor 30 from over-driving, asensing switch 80 is mounted at a proper place of the traveling path of thetelescopic unit 60 or theslide tube 40. Accordingly, the tilting action from the fold-up action can be effectively controlled by contact or release of thesensing switch 80. - A simple example will be described to detail the action of the
sensing switch 80 as follows: - When any
sensing switch 80 is touched during the operation of themotor 11 and the continuous movingbelt 15, it is programmed that themain frame 10 is located at a highest point of the tilting action so that no more lifting action is permitted. In this way, the liftingmotor 30 can be only operated in a reverse manner to lower the tiling angle of themain frame 10 relative to the inverted T-bases 20. Besides, thesensing switch 80 is inoperative when the continuous movingbelt 15 is out of operation. This results in a better safety in use. - The
telescopic unit 60 can be replaced by a pneumatic, a hydraulic cylinder (not shown) or other equivalent units for both enhancing the lifting effect and reducing the loading of the liftingmotor 30. - Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
