Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a tilting device for a treadmill.

[0002]

[Prior Art]

 Conventionally, as a tilting device for the treadmill 13, as shown in FIG. 7, a screw rod having a caster 14 at the lower end and grounded to the floor is provided at the front part of the treadmill frame 15 at right angles to the frame. It was generally known that the treadmill body was tilted by lifting the front part of the gantry by attaching it to and rotating the screw rod to feed it downward.

Further, as another structure, a tilting device for a treadmill such as US Pat. No. 4,591,147 shown in FIGS. 8 to 9 is also known. That is, in the treadmill of this structure, the arm 17 and the slide rod 18 are used to lower the protruding portion on the upper surface of the treadmill. However, with this structure, when setting an arbitrary inclination. In this method, the nut 19 is loosened and the slide rod 18 is adjusted manually.

Further, as another structure, a tilting device for a treadmill such as US Pat. No. 4,792,134 shown in FIGS. 10 to 11 is also known. That is, in the treadmill having this structure, the drive motor 20, the worm gear 21, the worm 22, the arc-shaped worm gear 23, and the shaft 24 are used to lower the protrusion of the upper surface of the treadmill.

[0005]

[Problems to be solved by the device]

 However, these conventional tilting devices for treadmills have the following problems to be solved. That is, among these conventionally known treadmills, a screw rod having a caster 14 as shown in FIG. 7 grounded to the floor through the lower end is attached to the front part of the base of the treadmill 13 at a right angle to the base, The structure in which the treadmill body is tilted by lifting the front part of the gantry by rotating the screw rod and sending it downwards requires a relatively long screw rod in order to obtain an inclination of about 25%. .. Therefore, when the treadmill 13 is returned to the horizontal state, the threaded rod protrudes from the upper surface of the treadmill body, which impairs the appearance and is dangerous even if the user falls down. Although a cover 16 has been devised to cover the treadmill drive device and the screw rod, it requires a considerably large cover as shown in the figure, which gives a feeling of pressure to the user and is unpopular. It had drawbacks. Therefore, there has been an idea to store the threaded rod in a pipe-shaped handrail, but since the threaded rod protrudes vertically, there are various design restrictions, and a treadmill with a smart design is supplied. I had a problem saying I couldn't do it.

Further, in the case of the tilting device of the treadmill 13 such as US Pat. No. 4,591,147 shown in FIGS. 8 to 9, it is possible to lower the protruding portion on the upper surface of the treadmill, but The adjustment had to be done manually. In addition, since the slide rod 18 is adjusted to fix it to an arbitrary inclination and then the nut 19 is tightened and fixed, the user cannot adjust the inclination by himself / herself while using the treadmill.

Further, in the case of the tilting device for the treadmill 13 as shown in US Pat. No. 4,792,134 shown in FIGS. 10 to 11, the protruding portion on the upper surface of the treadmill can be lowered similarly to the above-mentioned treadmill. However, in the treadmill having this structure, since the drive motor 20, the worm gear 21, the worm 22, the arc-shaped worm gear 23, and the shaft 24 are used, the structure becomes complicated and the arc-shaped worm gear 23 is used, so that the treadmill is used. There is a problem that the cost of the pedestal 13 is too high and the cost is high because the arcuate arm 23 having a special shape is used.

In view of these conventional drawbacks, the present invention simplifies the structure for inclining the treadmill mount and improves the parts used to reduce the protrusion on the upper surface of the treadmill. It is intended to provide a tilting device for a treadmill that is easy to take and durable.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention arranges a tilting device combining a drive motor, a nut, a screw rod, etc. at the end of a treadmill base, and rotates a tilting arm at the lower end of the screw rod. A roller mounted on the upper end of the tilting arm is movably fitted to a sliding guide formed on the end of the mount, and the tilting arm moves up and down the screw rod. When the tilting arm is tilted together, the roller at the upper end of the tilting arm slides in the sliding guide, and the caster attached to the lower end of the tilting arm rolls on the ground surface. As a result, the treadmill tilting device is characterized in that the pedestal can be vertically tilted.

[0010]

[Action]

 In the present invention, the tilt arm is rotatably attached to the lower end of the screw rod, and the roller provided on the upper end of the tilt arm is fitted to the sliding guide formed on the mount. Since the screw rod is used in this manner, the screw rod can be shortened by approximately 50% as compared with the conventional one. Therefore, the cover that covers the treadmill drive unit and the overall design can be made compact, and the degree of freedom in design can be improved.

Further, in the present invention, by using the sliding guide, the screw rod can be always moved up and down in the direction perpendicular to the pedestal. Therefore, the structure is simpler than the method disclosed in US Pat. Nos. 4,591,147 and 4,792,134, and it is not necessary to separately manufacture and use a specially shaped part, which reduces the cost. It will be possible to supply treadmills that are durable and durable.

Further, in the present invention, as compared with US Pat. No. 4,591,147, since a drive motor for tilting is used, the user can operate the switch at hand while using the treadmill. Thus, the inclination of the treadmill can be arbitrarily changed within the range of 0 to 25% and used.
