Referring to theFIG. 12 andFIG. 13 , the left and right side covers 234 respectively overlap the side rails 222. Therefore, there is anopen space 235 in front of each of the side rails 222 and the upper and lower sides thereof are through-opened. In another embodiment (not shown), the side rail extends to the front end of the tread base, and a concave is shaped in the front of the side rail, thus also forms a through-opened space. - Please refer to
FIG. 16 andFIG. 16A , theouter surface 223 of theside rail 222 of thetread base 220 and theouter surface 212 of theside member 211 of thebase frame 210 are approximately on the same vertical section. Moreover, the left and right side covers 234 on the front end of thetread base 220 are nearly next to theouter surface 223 of the side rails 222. So the lateral width of thetread base 220 and thebase frame 210 is almost the same (the outer surface on the front end of thetread base 220 includes the left and right outer surface of thecover unit 223 which has the outer surface of theupper cover 232 and the side cover 233). - Referring to
FIG. 17 , thelinkage assembly 250 is coupled between thetread base 220 and thebase frame 210. Thelinkage assembly 250 includes left and right linkingmembers 251 and left andright guide members 261. In this embodiment, each of the left and right linkingmembers 251 has amain plate 252 and a guidingplate 257 which having a first end welded on the middle of themain plate 252 and a guidedportion 258 formed in the second end thereof. Themain plate 252 has afirst end 253 pivoted to thetread base 220 and asecond end 254 which has an outward extendingaxis 255 and aroller 256 connected to the extendingaxis 255 rotated via the extendingaxis 255 and movable engaged with thegroove 213. - Still Referring to
FIG. 17 , a connectingrod 259 is welded between the left and right linkingmembers 251. In this embodiment, the connectingrod 259 is mounted next to the second ends 254 of the left and right linkingmembers 251. So that the connectingrod 259 can be moved close to the ground. By using the connectingrod 259, the left and right linkingmembers 251 can be moved more stably synchronously. - Each of the left and
right guide members 261 has afirst end 262 connected to theside member 211 of thebase frame 210 and asecond end 263 laterally pivoted with the guidedportion 258 of each of the left and right linkingmembers 251. - Referring to
FIG. 15 ,FIG. 15A ,FIG. 16 andFIG. 16A , the left and right linkingmembers 251 and the left andright guide members 261 are positioned inside the outer surface of thetread base 220 andbase frame 210. Furthermore, the left and right linkingmembers 251 are more inside than the left andright guide members 261. More particularly, each of themain plates 252 of the left and right linkingmembers 251 is parallel to the inner surface of theside member 211. While the guidingplates 257 are extended upward from themain plates 252 and through theopen space 235, the top ends of the guiding plates are higher than the side rails 222. Since theguide members 261 are crossly mounted between theside members 211 of thebase frame 210 and the left and right linkingmembers 251, when the treadmill is in use, the second ends 263 of the left andright guide members 261 could pass through theopen space 235 not only whentread base 220 is in the horizontal position, but also in the inclined position. - Referring to
FIG. 17 , theincline assembly 270 includes amotor 271 and aretractable member 272. Under thecover unit 231, themotor 271 mounted on the front of thetread base 220 is controlled by theconsole 244. Theretractable member 272 includes a screw and a sleeve. One end of theretractable member 272 is coupled to an output of themotor 271, and the other end is laterally pivoted to a pivoted seat which is mounted in the middle of the connecting rod via a hole on thelower cover 233. Thus the distance between the front end of thetread base 220 and the connectingrod 259 will be increased or shortened. - When the user wants to increase the elevation of the
tread base 220, he can operate theconsol 244 to extend theretractable rod 272 of theincline assembly 270. So that the front end of thetread base 220 is depart from the connectingrod 259. At this time, combining withFIG. 18 , the second ends 254 of the left and right linkingmembers 251 move backward together with the connectingrod 259. Simultaneously, the first ends 253 of the left and right linkingmembers 251 have to raise together with thetread base 220 and the guidedportions 258 are diverted by the left andright guide members 261. On contrary, when theretractable rod 262 of theincline assembly 270 is shortened, the frond end of thetread base 220 will be pulled down by theretractable rod 262. And the front ends of the left and right linkingmembers 251 will move forward to change the left and right linkingmembers 251 from the slant state ofFIG. 18 to the flat state ofFIG. 10 . - When the user folds the treadmill, it is better to adjust the
tread base 220 to the flat state and then lift the back end of thetread base 220 upward and forward. Referring toFIG. 19 , as the left and right linkingmembers 251 are non-movable relative to thetread base 220, thetread base 220 will rotate around the guidedportions 258 of the left and right linkingmembers 251. The higher the first ends 253 of the left and right linkingmembers 251 are raised together with thetread base 220, the more backward the second ends 254 of the left and right linkingmembers 251 are moved. Until thetread base 220 is rotated to the almost vertical state (80 degrees here), the treadmill will be at the foldable state as depicted inFIG. 20 andFIG. 21 , and an area occupied by thetreadmill 1 is just the proportion of thebase frame 210. - Referring to
FIG. 11 andFIG. 20 , anair spring 280 is coupled between atransverse rod 225 mounted at the bottom of thetread base 220 and thecross rod 215. Theair spring 280 has an extending trend because of the air elasticity therein. When thetread base 220 is in the flat state, theair spring 280 is compressed. So that the user can lift thetread base 220 easily from flat to folded state with the extending force of theair spring 280. Contrary, the elasticity of theair spring 280 can buffer the gravity of thetread base 220 and makes it falling slowly. The structure and application of theair spring 280 is the prior art of the foldable treadmill. - Referring to
FIG. 14 andFIG. 22 , there is a securingunit 290 mounted on the inside surface of theleft side member 211. The securingunit 290 can pitch thetread base 220 on the folded state, avoid collapse. The securingunit 290 includes ametal lever 291. The middle of themetal lever 291 is mounted on the inside surface of theside member 211. The front end of themetal lever 291 is consisted of a semicircle downwardhatch locking end 292, and the back end is consisted of apressing end 293 controlled by the user. Besides, a spring (not shown) between the front end of thelever 291 and thebase frame 210 pulls down the front side of thelever 291 and makes it flat asFIG. 14 . When thetread base 220 is rotated to the vertical state, the extendingaxis 255 on the outside surface of theleft linking member 251 moves to the frond end of thelever 291, then the front end of thelever 291 will be extruded open and then locked, and the lockingend 292 hooks the extendingaxis 255 asFIG. 22 . So that the front end of theleft linking member 251 can not move forward and thetread base 220 will not overturn. When the user pulls thetread base 220 from folded to flat state, he has to step on thepressing end 293, then the front end will be lifted and release theaxis 255. And the frond end of theleft linking member 251 can move forward again. The structure and action of the securingunit 290 is prior art. - Here, the left and right linking
members 251 and left andright guide members 261 can achieve the same or substantial action with different mechanisms. For example, the second ends 254 of the left and right linkingmembers 251 may be at the back of the first ends 253, and the guidedportion 258 may be superimposed thefirst end 253 or further from thesecond end 254 thanfirst end 253. Similarly, the first ends 262 of the left andright guide members 261 may be in the front of the second ends 263. - Besides, the side rails 222 of the
tread base 220 are not necessary to make use of the structure described above (discontinued or carved). During production, the side rails 222 can be extended to the front end of thetread base 220. But the left and right linkingmembers 251 and left andright guide members 261 must be moved further inward to the inside surface of the side rails 222. The reason for arranging the saidopen space 235 is to set the drivingassembly 229,incline assembly 270 and electronic unit and the left and right linkingmembers 251 and left andright guide members 261 do not to occupy the space inside of theside rail 222. - In the prior foldable treadmill, the lateral width of the base frame will larger than the tread base about 20 centimeters. So that the left and right linking member and the left and right guide member can be mounted therebetween. Referring to
FIG. 15 ,FIG. 15A ,FIG. 16 andFIG. 16A , in this invention, as the left and right linkingmembers 251 and left andright guide members 261 are inside the outer surface of the side rails 222 and also inside theside members 211. The outer surface of the left and right sides of thetread base 220 is above that of thebase frame 210, and the lateral width of thebase frame 210 and tread base is similar. In another embodiment, thetread base 220 is even wider than thebase frame 210. - From the above description, comparing to the prior treadmill, for this invention, the lateral width of the
base frame 210 is not larger than thetread base 220. So the lateral width of the treadmill in this invention will be narrow with the same as tread base. For the users, these kinds of treadmills occupies less space and easily to move and stow. For business, the smaller package of the product can improve the storage and transportation, especially for the shipment with container by truck or by sea. The advantage can increase the quantity in one container and cost down. - Additionally, the
linkage assembly 250 of this preferred embodiment is similar to that of Chinese Invention Patent Application 200420002326.X, but it may use the structure of the Chinese Invention Patent Application 200420064728.2. That is to say that the left and right guide members are connected to the base frame with the connect portions. And each of the left and right guide members includes a groove guide portion, and each of the guided portion of the left and right linking members is limited to move along the groove. Of course, the other similar art of linkage assembly will be used, combining with the art in this preferred embodiment to get the same effect and advantage. - The present invention does not require that all the advantageous features and all the advantages need to be incorporated into every embodiment thereof. Although the present invention has been described in considerable detail with reference to certain preferred embodiment thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred embodiment contained herein.
