Definitions

  • the invention relates to a treadmill that comprises a frame, a belt section arranged on the frame and comprising a belt arranged in an endless loop around two rolls at a distance from each other, first means for turning the belt around a front roll and a back roll at a desired speed, and second means for adjusting the tilt of the belt section with respect to the horizontal, and a hand support structure extending upward from the plane of the frame in the operating position of the treadmill and comprising a support part on both sides of the frame, whereby the frame is arranged to be an element turnable in the upright position.
  • Treadmills are today very popular devices, and they are used for instance at gyms and at home for exercises related both to keeping fit and to top athletics. Treadmills provide the advantage that they make it possible to do running exercises indoors, whereby the user is independent of weather conditions and large hall space.
  • the advantage of treadmills when used for keeping fit is that they make it possible to combine exercises with some other activity, such as watching television, which in a way allows for more time for the fitness exercise, because it can be combined with some other activity, such as watching a television program.
  • the treadmill of the invention is characterized in that an auxiliary frame that turns around a transverse shaft is fastened to the frame, and arms of the auxiliary frame extend parallel to the frame towards one end of the frame so that when the frame is lifted up, the auxiliary frame turns around the transverse shaft and the ends of the arms rest against the floor and form points of support that keep the frame upright.
  • the invention can also be implemented in such a manner that two auxiliary frames are used in the structure, whereby support parts of the hand support structure are fastened at their bottom ends to the first auxiliary frame and the frame is fastened in the area of one end to the first auxiliary frame so that it turns around a first transverse shaft, whereby the invention is characterized in that a second auxiliary frame that turns around a second transverse shaft is fastened to the frame, and arms of the second auxiliary frame extend parallel to the frame towards one end of the frame so that when the frame is lifted up around the first transverse shaft, the second auxiliary frame turns around the second transverse shaft and the ends of the arms rest against the floor and form points of support that keep the frame upright.
  • the invention provides above all the advantage that by means of the invention, it is possible to provide a simple and functional structure. Due to the simple structure, the maintenance need of the treadmill is small, whereby the operating costs of the device are low. As a result of the simple structure, the weight of the device does not become unreasonable, and the handling and moving of the device is easy. Turning the treadmill of the invention upright, i.e. to the transport and/or storage position, is a light operation. Yet, the hand support structure of the treadmill of the invention is very strong. The mechanics of the treadmill of the invention are simple. The invention provides the further advantage that its structure enables the delivery of the device fully assembled and the customer need not assemble it before using it.
  • FIG. 1 is a side view of a treadmill of a first embodiment of the invention in its operating position
  • FIG. 2 is a side view of the treadmill of FIG. 1 in a situation, in which the frame is turned upright,
  • FIG. 3 shows a treadmill of a second embodiment of the invention in its operating position
  • FIG. 4 shows the treadmill of FIG. 3 in a situation, in which the frame is turned upright
  • FIG. 5 shows a situation, in which a treadmill turned upright as shown in FIG. 4 is movable sideways
  • FIG. 6 shows a situation, in which the treadmill of FIG. 3 is turned into a low storage position
  • FIG. 7 shows a situation, in which the position of FIG. 6 is made even lower.
  • FIG. 1 shows the treadmill of the invention in its operating position, i.e. running position.
  • the treadmill is arranged to rest against the floor 1 .
  • the term ‘floor’ refers herein to any support surface on which the treadmill rests.
  • Reference number 2 marks the frame.
  • a belt section 3 is arranged on the frame 2 and comprises a belt 6 arranged in an endless loop around two rolls 4 , 5 at a distance from each other, the belt forming a plane on which the user of the device runs.
  • the treadmill further comprises first means 7 for turning the belt 6 around a front roll and a back roll at a desired speed, and second means 8 for adjusting the tilt of the belt section with respect to the horizontal.
  • the first means 7 comprise for instance an electric motor and an appropriate power transmission mechanism.
  • the second means 8 can, in some applications, comprise a suitable power source and a power transmission mechanism, such as an electric motor and rack transmission, or another suitable solution.
  • the second means 8 also comprise floor supports resting against the floor. The adjustment of the tilt can preferably take place by adjusting the floor supports. The adjustment can be motor-operated or manual.
  • the treadmill further comprises a hand support structure 9 extending upward from the plane of the frame 2 in the operating position, and the hand support structure comprises a support part 10 on both sides of the frame.
  • the hand support structure can also comprise a control and/or gauge panel 11 of the device. The size and shape of the control and/or gauge panel depends for instance on the adjustment options and other functions of the device.
  • Both support parts 10 of the hand support structure 9 are joined at their bottom ends to a first auxiliary frame 12 .
  • the frame 2 is in the area of its first end fastened to the first auxiliary frame 12 so that it turns around a first transverse shaft 13 .
  • An essential factor of the treadmill of the invention is that a second auxiliary frame 15 that turns around a second transverse shaft 14 is fastened to the frame 2 . Arms 16 of the second auxiliary frame 15 extend parallel to the frame 2 towards one end of the frame. The above-mentioned detail is clearly shown in FIG. 1.
  • the second auxiliary frame 15 is fastened to the frame 2 so that when the frame 2 is lifted up around the first transverse shaft 13 , the second auxiliary frame 15 turns around the second transverse shaft 14 , whereby the ends of the arms 16 rest against the floor 1 and for points of support to keep the frame 2 in the upright position.
  • the above-mentioned operating principle is especially clearly shown in FIG. 2.
  • the second transverse shaft 14 can be located at any suitable point of the frame 2 . To locate the second transverse shaft 14 at substantially the middle of the frame, as done in the example of the figures, has been found especially advantageous.
  • At least one element 17 easing the turning movement can preferably be arranged between the frame 2 and the second auxiliary frame.
  • the element 17 can be a gas spring, for instance.
  • the idea of the gas spring is that when the back part of the frame is lifted up from the floor, the gas spring lightens the lifting by pushing downward the second auxiliary frame pivoted to the frame so that when the lifting is continued, the situation shown in FIG. 2 is achieved.
  • Support wheels 18 rotating around substantially horizontal shafts can preferably also be arranged in the area of the ends of the arms 16 to facilitate the moving of the treadmill.
  • FIGS. 3 to 7 show a second embodiment of the treadmill of the invention.
  • the same reference numbers are used for similar parts in FIGS. 3 to 7 as in FIGS. 1 and 2.
  • FIGS. 3 to 7 only uses one auxiliary frame so that in the embodiment of FIGS. 3 to 7 , the auxiliary frame 15 corresponds to the second auxiliary frame 15 of the embodiment shown in FIGS. 1 and 2.
  • the transverse shaft 14 of the embodiment shown in FIGS. 3 to 7 corresponds to the second transverse shaft of the embodiment in FIGS. 1 and 2.
  • FIGS. 3 to 7 does not have an auxiliary frame in the front part of the frame 2 , but the front part of the frame rests directly against the floor.
  • the treadmill of FIGS. 3 to 7 is turned into the upright position in a similar manner as described earlier in connection with FIGS. 1 and 2.
  • the frame is for instance lifted up from its back end, whereby the auxiliary frame 15 turns around the transverse shaft 14 and the ends of the arms 16 rest against the floor and form points of support to keep the frame in the upright position.
  • the hand support structure is arranged turnably to the frame 2 , whereby a relative turning movement is obtained between the frame and the hand support structure 9 , as shown in FIGS. 5 and 7, for instance.
  • the turning movement can, if necessary, be lightened by means of the element 17 easing the turning movement, for instance a gas spring, that is arranged between the frame 2 and the auxiliary frame 15 .
  • FIGS. 6 and 7 show an additional advantage achieved by the invention.
  • the device of the invention can be put into a low storage position, in which case the device easily fits into a low storage space.
  • the treadmill of the invention can be put into the above-mentioned low storage space by turning the hand support structure substantially parallel to the frame, as shown in FIG. 6.
  • the structure can be made even lower by also making the control and/or gauge panel 11 into a turnable part, whereby said part can be further turned substantially parallel to the frame, as shown in FIG. 7.
  • FIGS. 3 to 7 can be equipped with different support wheels depending on how the device shall be moved.
  • reference number 18 marks support wheels rotating around substantially horizontal shafts to facilitate the moving of the points of support when the device is lifted.
  • reference numbers 19 and 20 mark wheels that enable the moving of the device sideways.
  • the wheels can be made movable, like the wheels 20 in FIGS. 3 to 7 that can be lowered when the device needs to be moved sideways. Such a situation is shown in FIGS. 4 and 5. Movability can be achieved by means of a simple shaft moving in a link or by another suitable mechanism.
  • the wheels 19 and 20 can also be applied to the embodiment of FIGS. 1 and 2.
  • the support wheels can be not only fixed, but also movable solutions, whereby they can be lowered down for the move and, correspondingly, raised up when the treadmill is to remain in place.
  • the above-mentioned wheels can naturally also be made turnable around a vertical shaft and lockable to a desired position, and they can be equipped with a brake mechanism to ensure that the device remains in place.
  • the treadmill of the invention can naturally also be equipped with means for locking the frame in both the running and upright position, etc. Any means known per se can be used as the above locking means, for instance pin locking means, latch means, or the like.
  • the first and second means which rotate the belt and adjust the tilt angle of the frame, are located in the front part of the frame, and the frame is lifted upright by lifting it up from the back end.
  • the structure can also be implemented in other ways; for instance, the first and second means can also be placed in the back part of the frame, whereby the lighter front end of the frame is preferably lifted up when the frame is raised to the upright position.
