Description

    BACKGROUND OF THE INVENTION 1. Field of the Invention
  • The present invention relates to treadmill technology and more particularly, to a running deck equipped with an endless slat belt for use in a treadmill. The invention relates also to an endless slat belt for the running deck.
    • 2. Description of the Related Art
  • U.S. Pat. No. 8,864,627 discloses a manually operated treadmill adapted to generate electrical power comprising a treadmill frame, a running belt supported upon the treadmill frame and adapted for manual rotation, and an electrical power generator mechanically interconnected to the running belt and adapted to convert the manual rotational motion of the running belt into electrical power. However, due to the use of interconnecting members to interconnect belt components of the running belt and the arrangement of rollers in the treadmill frame, this design of treadmill has the drawbacks of having a large amount of component parts and a complicated structure.
  • Referring to FIGS. 1 and 2, Taiwan Patent M404030 discloses a treadmill, which comprises a support frame 11, two turntables 12 pivotally mounted in the support frame 11 and respectively disposed adjacent to opposing front and rear sides thereof, and an endless slat belt 13 mounted around the two turntables 12. The support frame comprises two reinforcing ribs 111 located at the top side thereof. The endless slat belt 13 comprises a plurality of slats 131, a plurality of links 132 respectively pivotally connected between one respective end edge of each of two adjacent slats 131 at each of two opposite lateral sides, a plurality of rollers 133 respectively pivotally connected to the respective ends of each two adjacent links 132, and a plurality of screw bolts 134 respectively and pivotally connecting the respective rollers 133 and the respective pair of links 132 to the respective slats 131.
  • When the endless slat belt 13 is driven to rotate by an external force, the rollers 133 can be smoothly and rotatably moved along the reinforcing ribs 111. Subject to meshing engagement relationship between the turntables 12 and the endless slat belt 13, the endless slat belt 13 can be smoothly rotated around the turntables 12. Thus, the rollers 133 and the links 132 are interconnected to the slats 131, achieving a streamline configuration.
  • However, in the aforesaid prior art designs, since the rollers 133 and the links 132 are interconnected to the respective opposite end edges of the slats 131, two large spaces must be respectively provided between the two opposite inner sides of the support frame 11 and the end edges of the slats 131 for accommodating the rollers 133 and the links 132 without interfering with their movement. Thus, a large clearance d is left between each end edge of each slat 131 and the support frame 11, making the overall appearance of the treadmill less aesthetically pleasing. Further, in order to mount the screw bolts 134, the thickness t of the slats 131 must be relatively thick, and thus, the thickness and weight of the slats 131 cannot be minimized.
    • SUMMARY OF THE INVENTION
  • The present invention has been developed in view of the above identified circumstances. It is one of the main objects of the present invention to provide a running deck with an endless slat belt for a treadmill, which minimizes the thickness and weight of the slats of the endless slat belt thereof and has the characteristics of a simple structure with reduced thickness, light weight, and enhanced overall sense of beauty.
  • To achieve this and other objects of the present invention, a running deck comprises a frame and an endless slat belt. The frame comprises a plurality of opposing sliding surfaces. The endless slat belt is rotatably mounted around the frame, comprising a plurality of slats, and two chains interconnecting the slats. Each slat comprises an inner surface facing toward the sliding surfaces. Each chain comprises a plurality of chain links pivotally connected to one another and respectively joined to the respective inner surfaces of the slats, and a plurality of rollers respectively pivotally mounted in the chain links and rotatably movable along one respective sliding surface.
  • Subject to the arrangement of the chains on the inner surfaces of the slats to interconnect the slats and to slide along the sliding surfaces of the frame, the endless slat belt can be smoothly rotated around the frame, and thus, the running deck has the characteristics of simple structure, light weight and enhanced overall sense of beauty.
