DETAILED DESCRIPTION OF THE INVENTION
• Referring to the drawings and initially toFIGS. 1-3, a treadmill in accordance with the preferred embodiment of the present invention comprises a main body1, and an angle adjustingdevice2 mounted on the main body1.
• The main body1 includes twoupright bars11, twobottom rods12, aholding bar13, twoside rods14, an uppertransverse rod15, a lowertransverse rod16, aroller17, asupport board18, and abelt19. Thesupport board18 is mounted between the twoside rods14, and thebelt19 is mounted on thesupport board18. The uppertransverse rod15 is located between the twoside rods14.
• The angle adjustingdevice2 is mounted between theholding bar13 and each of the twobottom rods12 and includes asupport seat21, anangle adjuster22, abolt23, and asocket24.
• Thesupport seat21 is a triangular hollow body mounted on a respective one of thebottom rods12. Thesupport seat21 has a front side provided with afirst cover plate212 and a rear side provided with asecond cover plate214. Thesupport seat21 has two side walls each formed with an arc-shaped guide slot213 to function as an adjusting track of thebolt23.
• Theangle adjuster22 is mounted between theholding bar13 and the support seat21 (or a respective one of the bottom rods12) and includes a first connectingsection225 secured to theholding bar13 to move therewith, and a second connectingsection226 secured to thesupport seat21 and pivotally connected to the first connectingsection225. Preferably, the second connectingsection226 of theangle adjuster22 is secured to an inner side of thesecond cover plate214 of thesupport seat21. Thus, theholding bar13 is pivotally mounted on thebottom rods12 by theangle adjuster22.
• Theangle adjuster22 has an inside provided with agear222, anelastic member223, and alocking pawl224. Thelocking pawl224 of theangle adjuster22 is engaged with thegear222 to adjust the angle between the first connectingsection225 and the second connectingsection226.
• Thesocket24 is mounted between the two side walls of thesupport seat21, and thebolt23 is extended through theguide slots213 of thesupport seat21, thesocket24 and the front end of each of the twoside rods14 and is screwed into an end of the uppertransverse rod15, so that the uppertransverse rod15 is combined with the twoside rods14 by thebolt23. At this time, thebolt23 is located above and rested on theholding bar13 extended into thesupport seat21 as shown inFIG. 2.
• In operation, referring toFIGS. 4-7, when theholding bar13 is moved upward by the user, thebolt23 is moved upward by theholding bar13, so that the uppertransverse rod15 and the front ends of the twoside rods14 are moved upward by thebolt23 so as to adjust the angle of thesupport board18 mounted between the twoside rods14. At this time, the first connectingsection225 of theangle adjuster22 is secured to theholding bar13 to move therewith, and thelocking pawl224 of theangle adjuster22 is engaged with thegear222 to fix the lifting angle of the first connectingsection225 so as to fix and adjust the angle of thesupport board18 mounted between the twoside rods14. Alternatively, as shown inFIGS. 4 and 5, when thegear222 of theangle adjuster22 is rotated to its end, theelastic member223 springs thelocking pawl224 away so that the first connectingsection225 is returned to the original position.
• As shown inFIGS. 7 and 8, when thebolt23 is unscrewed from the uppertransverse rod15, the front ends of the twoside rods14 are released from the uppertransverse rod15, so that the twoside rods14 and thesupport board18 are lifted toward theupright bars11 to move upward from the position as shown inFIG. 7 to the position as shown inFIG. 8 to fold thesupport board18 so as to reduce the volume of the treadmill when not in use, thereby facilitating storage and transportation of the treadmill. At this time, thesupport board18 is perpendicular to thebottom rods12.
• Referring toFIGS. 9-12, theangle adjuster22 is mounted between the lowertransverse rod16 and a respective one of the twoside rods14, wherein the first connectingsection225 is secured to the lowertransverse rod16 to move therewith, and the second connectingsection226 is secured to a respective one of the twoside rods14. Thus, when the lowertransverse rod16 is moved inward, the rear ends of the twoside rods14 are moved upward so as to adjust the angle of thesupport board18 mounted between the twoside rods14.
• Accordingly, when theholding bar13 is moved upward by the user, thebolt23 is moved upward by theholding bar13, so that the uppertransverse rod15 and the front ends of the twoside rods14 are moved upward by thebolt23 so as to adjust the angle of thesupport board18 mounted between the twoside rods14. In addition, the user only needs to hold and lift theholding bar13 so as to adjust the angle of the support board, thereby facilitating the user adjusting the angle of the support board.
• Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
