Abstract
A universal roller unit for a treadmill having a supporting frame and a platform. The supporting frame includes a front and a rear bar at the bottom thereof. A roller is pivotally connected to both ends of the front bar. A universal roller unit is attached to the middle part of the rear bar. When the treadmill is in a flat operational position, the universal roller unit may be attached to the side wall of the rear bar; when the treadmill is in a folded storage position, the universal roller unit may be pushed outwards to allow the universal roller to contact with the ground so that the universal roller and the rollers take the responsibility of supporting the whole weight of the treadmill and move the treadmill stably and freely in any direction.
Description
- 1. Fields of the Invention
- The invention relates to a roller unit for a treadmill, and more particularly, to a roller unit having improved convenience in use.
- 2. Description of the Prior Art
- Rollers fitted at the bottom of treadmills are used to facilitate a smooth movement of the treadmill, thereby achieving the laborsaving effect. A typical product is disclosed in U.S. Pat. No. 5,672,140 that describes roller sets are axially and pivotably arranged at one end of the ground-touching cross bars at both sides of the bottom of the treadmill while the roller sets in storage position are not in contact with the ground. In use, the roller sets are used as a pivoting point to incline the main body of the treadmill so as to facilitate the movement of the treadmill. Although this prior art can exactly reach the expected effect, it's difficult for weak people to incline the heavy treadmill during its whole movement. Even, this could lead to an unnecessary accident.
- Besides, the design of four rollers directly and permanently in contact with the ground can be seen in U.S. Pat. No. 5,372,559. However, this kind of structure will cause an unexpected sliding or shaking when the treadmill is operated. As a result, the safety of the user is seriously affected and it gradually becomes extinct on the market.
- In order to effectively resolve the above-mentioned problems, a support member is provided at proper position of the roller set so as to increase the frictional resistance with the ground. This structure is disclosed in U.S. Pat. No. 6,090,016. However, a swinging see-saw effect will be created when the treadmill is moved on an uneven surface, thereby leading to inconvenience and difficulty of the horizontal adjustment.
- In consideration of the above-mentioned, the inventor of the present invention thinks that the displacement of the treadmill is not a regular action. In operational position, it's not required to use the roller sets. In storage position, it's not necessarily required to shift the treadmill. As a result, partial roller sets can be stored and kept away from the ground so as to eliminate the unexpected sliding shift. In brief, all rollers are pulled out only when it's really required to displace the treadmill. It's therefore an object of the invention to provide a room for accommodating a universal roller unit at the side wall of a rear bar of the supporting frame, thereby eliminating potential drawbacks of the conventional treadmill in respect of the design and the application.
- 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 treadmill with a universal roller unit in accordance with the invention; -
FIG. 2 is a side view of the treadmill ofFIG. 1 in a flat operational position; -
FIG. 3 is a perspective exploded view of the universal roller unit and the supporting frame in accordance with the invention; -
FIG. 4 is a side view of the treadmill ofFIG. 2 in a folded position, showing that the front bar of the supporting frame tilts to the side; -
FIG. 5 is a side view of the treadmill ofFIG. 2 in a folded position, showing that the universal roller is swiveled outwardly in an operational position; and -
FIG. 6 is a side view of the treadmill ofFIG. 2 in a folded position, showing that the universal roller is in contact with the ground. - Referring to
FIGS. 1, 2 and 3, atreadmill 10 in accordance with the invention includes: - a supporting
frame 20 positioned at the front end of aplatform 30, ahandrail 21 and anelectric console 22 being disposed above the supportingframe 20, a front and arear bar frame 20, aroller 25 being provided at both ends of thefront bar 23, respectively, auniversal roller unit 40 being provided in the middle of therear bar 24; - a
platform 30 in rectangular shape having acontinuous belt 32 driven by a motor transmission unit (not shown) and movable around theplatform 30, asupport bar 34 being fitted to the bottom of the rear end of theplatform 30. By assembling the above-mentioned components, theplatform 30 on the supportingframe 20 can be folded in an upright storage position or in a flat operational position. - The
universal roller unit 40 includes: - an
angle iron 41 attached to the side wall of therear bar 24 in cooperation with afastening element 42 and acompression pin 43; - a
compression pin 43 passing through aborehole 26 in therear bar 24, thecompression pin 43 having different outer diameters, theborehole 26 also having different inner diameters at both ends thereof so that an unexpected detachment of thecompression pin 43 from theborehole 26 can be avoided; and - a
universal roller 44 in cooperation with apivot 45 and twospring elements 46 pivotally connected to a positioningear 27 under theborehole 26 of therear bar 24. - In the ordinary state, the
universal roller 44 is upwardly swiveled to contact with a corresponding end of thecompression pin 43. - When the
platform 30 is in flat operational position, theuniversal roller unit 40 is attached to the side wall of therear bar 24 without contact to the ground. When theplatform 30 is in folded position, as shown inFIGS. 4 through 6 , the operator may push theangle iron 41 together with thecompression pin 43 in the direction of theuniversal roller 44. In this way, theuniversal roller 44 is swiveled to the ground. Meanwhile, the operator put thetreadmill 10 down to allow theuniversal roller 44 to contact with the ground. At that time, theuniversal roller 44 and therollers 25 at both sides of thefront bar 23 take the responsibility of supporting the whole weight of thetreadmill 10 and move thetreadmill 10 stably and freely in any direction. - To bring the
universal roller unit 40 back to the storage position, thetreadmill 10 is required to tilt to the side while theangle iron 41 is pulled back in the reverse direction. - 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.
