Description
- This application claims priority of Taiwanese Patent Application No. 106134499, filed on Oct. 6, 2017.
- The disclosure relates to a type of exercise equipment, and more particularly to a treadmill.
- A treadmill provides a moving platform for a user to walk at a given movement speed while staying at the same place, and may also passively resist user motion for workout purpose. A conventional treadmill disclosed in Taiwanese Utility Model Patent No. 128972 includes a plurality of spaced-apart rollers mounted rotatably between two ends of the treadmill. The conventional treadmill allows a user to walk thereon and to drive rotation of each of the rollers. Another conventional treadmill disclosed in Taiwanese Utility Model Patent No. M401455 includes a plurality of rollers mounted on a hollow frame and operable to support a conveyor belt for rotation.
- Although both the abovementioned treadmills are capable of achieving intended purpose as a moving platform, the conventional treadmill disclosed in Taiwanese Utility Model Patent No. 128972 lacks a conveyor belt, such that only the rollers that are stepped on would rotate. Consequently, adjacent rollers would have different rotational speed, making it easier for the user to lose control of the movement speed on the treadmill and potentially slip.
- However, even with the addition of a conveyer belt in the treadmill as disclosed in Taiwanese Utility Model Patent No. M401455, the conveyer belt is only able to transmit walking movement of the user into rotation of the rollers that are in direct frictional contact with the conveyor belt, which are limited to those that are right underneath the user's feet. As such, the other rollers not in direct frictional contact do not gain as much rotational speed from the conveyer belt, resulting in different rotational speed between the rollers, which may easily pull and damage the conveyer belt.
- Besides the inability to control movement speed on the treadmill, the abovementioned prior arts also lack the capability to adjust workout intensity for the user.
- Therefore, an object of the disclosure is to provide a treadmill that can alleviate at least one of the drawbacks of the prior art.
- According to the disclosure, the treadmill includes a frame unit and a roller unit. The frame unit has a front end portion and a rear end portion that is opposite to the front end portion. The roller unit includes a plurality of spaced apart rollers and a plurality of linkage members. The rollers are mounted rotatably between the front end portion and the rear end portion, each of the rollers having a roller wheel. Each of the linkage members links a corresponding adjacent pair of the rollers to drive synchronized rotation of each of the rollers.
- Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
-
FIG. 1 is a perspective view of a first embodiment of a treadmill according to the disclosure; -
FIG. 2 is an exploded perspective view of the first embodiment; -
FIG. 3 is a fragmentary partly exploded perspective view of a roller unit of the first embodiment; -
FIG. 4 is a sectional side view of the first embodiment; -
FIG. 5 is a sectional view taken along line V-V ofFIG. 4 ; -
FIG. 6 is an enlarged fragmentary view ofFIG. 5 ; -
FIG. 7 is an exploded perspective view of a second embodiment of the treadmill according to the disclosure; and -
FIG. 8 is a sectional side view of the second embodiment. - Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
- Referring to
FIGS. 1, 2 and 4 , the first embodiment of the treadmill according to the disclosure includes aframe unit 10, aroller unit 20, and adamping unit 40. - The
frame unit 10 includes abase frame 11 that has two spaced-apartside frame boards 113. Theside frame boards 113 cooperatively have afront end portion 111, and arear end portion 112 that is opposite to thefront end portion 111, and a plurality of spaced-apart roller slots 114 formed between thefront end portion 111 and therear end portion 112. Thebase frame 11 further includes a plurality ofshafts 12 that extend in an axial direction (L) and are mounted rotatably to thebase frame 11, and ahandle frame 13 mounted to thebase frame 11. - The
roller unit 20 includes a plurality of spaced-apart rollers 21 and a plurality oflinkage members 22. Therollers 21 are mounted rotatably between thefront end portion 111 and therear end portion 112 of theframe unit 10. Each of therollers 21 extends in the axial direction (L), and has acylinder body 211 that has two opposite ends and aroller wheel 212 that is mounted to one of the ends of thecylinder body 211. In addition, theroller wheel 212 of each of therollers 21 is proximate to theroller wheels 212 of a corresponding adjacent pair of therollers 21. In this embodiment, as shown inFIGS. 3 and 6 , thecylindrical body 211 of each of therollers 21 has twocoupling members 214 that engage respectively a corresponding pair of theroller slots 114 that are aligned with each other in the axial direction (L). Theroller wheel 212 of each of therollers 21 has a plurality ofannular positioning grooves 213 that are spaced apart in the axial direction (L). As shown inFIGS. 5 and 6 , each of thelinkage members 22 is configured as a toothed belt that is trained on theroller wheel 212 of a corresponding adjacent pair of therollers 21, so as to link the corresponding adjacent pair of therollers 21 to drive synchronized rotation of each of therollers 21. - The
damping unit 40 includes amounting seat 41 that is mounted to thefront end portion 111 of theframe unit 10, adamping wheel 42 that is mounted rotatably to themounting seat 41, atransmission member 43 that interconnects thedamping wheel 42 and theroller wheel 212 of one of therollers 21, a retardingmember 44 that is disposed on themounting seat 41 for creating frictional contact with thedamping wheel 42, and an adjustingmember 45 that is connected to the retardingmember 44. - Referring to
FIGS. 1, 4, 5 and 6 , therollers 21 of theroller unit 20 cooperatively define a concavetop surface 210 for supporting the user. Because theroller wheels 212 of each of the corresponding adjacent pairs of therollers 21 are linked by a corresponding one of thelinkage members 22, when the user walks on thetop surface 210 to drive rotational movement of one or more of therollers 21, allother rollers 21 would be synchronized to rotate as well. All of therollers 21 are forced to maintain the same rotational speed, whether or not the user walks fast or slowly thereon. - In addition, for the purpose of exercising, the adjusting
member 45 is operable to drive the retardingmember 44 to be proximate to or distant from thedamping wheel 42, thereby adjusting friction between the retardingmember 44 and thedamping wheel 42. As thetransmission member 43 interconnects thedamping wheel 42 and one of therollers 21, adjustment to the retardingmember 44 directly adjust rotational damping of therollers 21 as well, allowing the user to exercise with the treadmill under different workout intensity. - Referring to
FIGS. 7 and 8 , the second embodiment of the treadmill of the disclosure is similar to that of the first disclosure, with an addition of aconveyer belt 30. Theconveyor belt 30 is mounted on thebase frame 11 of theframe unit 10 and surrounds theroller unit 20. Theconveyer belt 30 is supported by theshafts 12 and theroller unit 20, and is driven by theroller unit 20 to rotate relative to theframe unit 10. Given that therollers 21 are operable to maintain synchronized rotation due to the linking oflinkage members 22, theconveyer belt 30 is able to effectively transmit walking movement of the user into rotation of therollers 21 that are in direct frictional contact with theconveyor belt 30, as well as therollers 21 that are not. Theconveyer belt 30 is also able to rotate smoothly without wearing from therollers 21. As such, the second embodiment has the same advantage as those of the first embodiment. - In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects.
- While the disclosure has been described in connection with what are considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
